Technical Field
[0001] The present invention relates to a dehumidifier. More particularly, the present invention
relates to dehumidifier in which a flow path of air circulating along a plurality
of heat exchangers is formed in a closed-circuit.
Background Art
[0002] Generally, a dehumidifier is an appliance that sucks damp air into a case, allows
the sucked damp air to pass through a heat exchanger to remove moisture from the sucked
air, and discharge the air from which the moisture is removed to an indoor space,
thereby lowering the humidity in the indoor space.
[0003] The dehumidifier of the related art functions to perform a dehumidifying operation
in an air conditioner that has a compressor and other components to form a cooling/
heating cycle. Therefore, the dehumidifier has relatively lower dehumidifying efficiency
and causes the increase of the weight of the air conditioner.
[0004] Further, the dehumidifier of the related has a water tank built therein. Therefore,
in order to dump out the water from the water tank, the user has to separate the water
tank from the dehumidifier after stopping an operation of the dehumidifier and removing
a dehumidifier case. This is troublesome for the user.
[0005] JP2002 326012A discloses a dehumidifier having a drain pan located under an evaporator to catch
condensation forming on the evaporator.
[0006] WO 2006/135171 discloses a dehumidifier upon which the preamble of appending claim 1 is based.

Technical Problem
[0007] An object of the present invention is to provide a dehumidifier that is light and
compact while having an adsorption member for adsorbing moisture contained the air,
a plurality of heat exchangers, and a heater assembly for heating a circulation air.
[0008] Another object of the present invention is to provide a dehumidifier that is configured
to easily dump out condensed air.
Technical Solution
[0009] To achieve these objects and other advantages and in accordance with the purpose
of the invention, as embodied and broadly described herein, there is provided a dehumidifier
according to claim 1.
Advantageous Effects
[0010] According to the dehumidifier of the present invention, since the dehumidifier is
independently provided from an air conditioner, no compressor is required and thus
a weight of the product can be reduced. Further, the dehumidifying efficiency can
be enhanced.
[0011] Further, the support and water tank is provided under the main body and the water
tank is configured to be separated from the support in a side direction. When the
water tank is separated from the dehumidifier, the condensed water is temporally stored
in the drain pan. Accordingly, it is easy to dump out the water from the water tank
and there is no need to stop the operation of the dehumidifier during dumping out
the water from the water tank.

Best Mode for Carrying Out the Invention
[0013] Reference will now be made in detail to the preferred embodiments of the present
invention, examples of which are illustrated in the accompanying drawings. The invention
may, however, be embodied in many different forms and should not be construed as being
limited to the embodiments set forth herein; rather, these embodiments are provided
so that this disclosure will be thorough and complete, and will fully convey the concept
of the invention to those skilled in the art.
[0014] Fig. 1 is a perspective view of a dehumidifier according to an embodiment of the
present invention.
[0015] Referring to Fig. 1, a dehumidifier of this embodiment includes a main body 100 for
receiving a plurality of major components and a water container 300 and a support
310 that are disposed under the main body 100.
[0016] The main body 100 includes a main body case 110 formed in a rectangular container
having opened top and bottom and a top panel 120 mounted on the top of the main body
case 110.
[0017] The front case 110 defining front, rear, left, and right sides of the main body 100.
That is, the front case 110 includes a front panel 112 defining the front side, a
rear panel 114 (see Fig. 6) defining the rear side, a right panel 116 defining the
right side, and a left panel 118 defining the left side.
[0018] The front, rear, left, and right panels 112, 114, 118, and 116 are integrally formed
with each other such that the top and bottom of the main body case 110 are opened.
Accordingly, the bottom of the main body case 110 is closed by a main body base 150
that will be described hereinafter.
[0019] Fig. 2 is a first side exploded perspective view of the dehumidifier of Fig. 1, Fig.
3 is a second side exploded perspective view of the dehumidifier of Fig. 1, Fig. 4
is a front perspective view of an internal structure of the dehumidifier according
to an embodiment of the present invention, and Fig. 5 is a rear perspective view of
the internal structure of the dehumidifier of Fig. 4. In addition, Fig. 6 is an exploded
perspective view of a main case and top panel of the dehumidifier according to an
embodiment of the present invention and Fig. 7 is a rear perspective view of an inner
heat exchanger of the humidifier according to an embodiment of the present invention.
[0020] Referring to Figs. 2 through 7, the top panel 120 defines an outer appearance of
the top of the main body 100. The top panel 120 is installed to be spaced apart from
an upper end of the main body case 110 with a predetermined gap.
[0021] Accordingly, the gap between the top panel 120 and the upper end of the main body
case 110 functions as an air outlet 122 through which the air is discharged.
[0022] In more detail, an edge of the top panel is installed to be spaced apart from the
upper end of the main body case 110 with a predetermined gap. That is, as shown in
the drawings, a predetermined gap is formed between the edge of the top panel 120
and the front, rear, left and, right panels 112, 114, 118, and 116. That is, as described
above, the air outlet 122 through which the dehumidified air is discharged is formed.
[0023] For descriptive convenience, air that is introduced from an external side (an indoor
space) of the dehumidifier into an interior side of the dehumidifier and subsequently
discharged into the indoor space will be referred to as 'air. In addition, air circulating
along a plurality of heat exchangers 200, 210, and 220, a recovery assembly 160, and
a heater assembly, which will be described later, will be referred to as 'circulation
air.
[0024] Spacing projections 124 are provided between the top panel 120 and the main body
case 110 to form the gap between the top panel 120 and the main body case 110. The
spacing projections 124 is formed having a predetermined height to support the top
panel 120, thereby allowing the top panel 110 to maintain a predetermined space from
the upper end of the main body case 110.
[0025] The spacing projections 124 protrude upward from the upper end of the main body case
110. In more detail, the spacing projections 124 are formed on respective corners
of the upper end of the main body case 110. Each of the spacing projections 124 is
formed in a thin cylindrical shape. That is, the top panel 120 is provided at four
corners of the bottom surface with projection grooves 126 corresponding to the spacing
projections 124. The spacing projections 124 are fixedly inserted in the corresponding
projection grooves 126.
[0026] The main body case 110 is provided at one surface (right surface) with air inlets
128 through which the air is introduced. That is, the air inlets 128 are formed on
the right panel 116. The air inlets 128 define passages along which the air is introduced
into the main body case 110. Each of the air inlets 128 may be formed in a slit shape
extending in a horizontal direction.
[0027] Alternatively, each of the air inlets 128 may be formed in a slit shape extending
in a vertical direction. Instead of forming the air inlets on the right panel 116,
a separate air inlet grille may be detachably installed on the right panel 116.
[0028] A barrier 130 dividing an interior space of the main body 100 into front and rear
spaces is provided in the main body 100. That is, the barrier 130 is bent at a plurality
of portions. That is, as shown the drawings, when viewed from the top, the barrier
130 is formed in' '-shape.
[0029] The barrier 130 is provided at a right end portion with a rearward extending portion
130a that is vertically bent rearward. The rearward extending portion 130a is further
bent rightward to form a rightward extending portion 130b. The rightward extending
portion 130b is further bent at a predetermined angle to form an inclined end portion
130c.
[0030] The inclined end portion 130c is formed having an acute angle with respect to an
extending line of the rightward extending portion 130b and contacts a rear end of
the right panel 116 and a right end of the rear panel 114. Therefore, the inclined
end portion 130c allows the external air introduced through the air inlet of the right
panel 116 to be effectively introduced into a front portion of the barrier 130.
[0031] The barrier 130 is configured to have a height that is same as or less than a height
of the main body case 110. Accordingly, a gap is formed between an upper end of the
barrier 130 and the top panel 120. The reason for forming the gap between the upper
end of the barrier 130 and the top panel 120 is to allow the dehumidified air to flow
upward at a rear side of the barrier 130 and subsequently flows to the front side
of the barrier 130 through the gap between the barrier 130 and the top panel 120.
Therefore, the dehumidified air can be discharged to an external side through the
gap between the top panel 120 and the front panel 112.
[0032] A rearward recess 132 having a predetermined size is formed on the barrier 130. The
rearward recess 132 is formed at a center of the barrier 130 and recessed rearward.
A heater assembly 170, a blower fan 246, and an inner heat exchanger 200 are installed
in the rearward recess 132.
[0033] The rearward recess 132 is provided at a center with a central through hole 134.
The central through hole 134 functions as a passage through which the air flows from
the front side of the barrier 130 to the rear side of the barrier 130.
[0034] A motor support 136 is formed on a central portion of the central through hole 134.
The motor support 136 is a portion on which the blower motor 240, the blower fan 246,
and the heater assembly 170 are mounted.
[0035] The motor support 136 is formed on a central portion of the central through hole
134 and a plurality of support guides 136' (four support guides) extending in a radial
direction is formed on the motor support 136. Therefore, the motor support 136 is
integrally formed with the barrier 136.
[0036] An adsorption motor receiving portion 138 is formed on a side of the motor support
136. The cylindrical adsorption motor receiving portion 138 is formed on a left-upper
half of the central through hole 134. The adsorption motor receiving portion 138 is
a portion on which an adsorption motor 176 is mounted. The adsorption motor receiving
portion 138 is formed in a cylindrical shape opened frontward. The adsorption motor
receiving portion 138 may be integrally formed on the rearward recess 132.
[0037] The rearward recess 132 is provided with a heater receiving portion 140. The heater
receiving portion 140 is a portion on which the heater assembly 170 is mounted. The
heater receiving portion 140 is formed on a left portion of the rearward recess 132.
Heater guides for supporting upper and lower ends of the heater assembly 170 is formed
to extend frontward from the rearward recess 132.
[0038] A recovery receiving portion 144 is formed above the heater receiving portion 140.
A predetermined space is defined above the heater guide 142 of the barrier 130 to
form the recovery receiving portion 144. The recovery assembly 160 is installed in
the recovery receiving portion 144.
[0039] The barrier 130 is provided with an air outlet 146 opened frontward. The air outlet
146 is a portion through which the circulation air is discharged. The air outlet 146
is formed on a right lower end of the rearward recess 132 of the barrier 130. Therefore,
the circulation air discharged front side through the air outlet 146 is introduced
into the inner heat exchanger 200.
[0040] A cylindrical air inlet 146' is formed extending from a right portion of the barrier
130. That is, as shown in the drawing, the cylindrical air inlet 146' is formed extending
rightward from a right lower end of the barrier 130. The air inlet 146' is a portion
for guiding the circulation air discharged from a side heat exchanger 220, which will
be described later, to an interior side of the barrier 130.
[0041] The air inlet 146' and the air outlet 146 communicate with each other. Therefore,
the circulation air introduced into the barrier 130 through the air inlet 146' is
discharged again through the air outlet 146.
[0042] The airflow guide 148 is formed on a rear surface of the barrier 130. The airflow
guide 148 functions to guide the flow of the air that is forcedly directed by the
blower fan 246. That is, airflow guide 148 allows the air discharged in a circumferential
direction by the blower fan 246 to flow toward the left upper portion. The blower
fan 246 is integrally formed extending from the rear surface of the barrier 130.
[0043] The airflow guide 148 includes a circular guide portion 148' enclosing an outer side
of the blower fan 246 and an upper guide portion 148" formed extending upward from
the circular guide portion 148'. The circular guide portion 148' is a portion for
primarily guiding the air discharged in the circumferential direction by the blower
fan 246. The upper guide portion 148" is a portion for allowing the air guided leftward
by the circular guide portion 148' to flow upward.
[0044] A main body base 150 is provided on a lower end of the barrier 130. The main body
base 150 is formed in a rectangular plate shape to define a bottom of the main body
100 and support a plurality of components including the barrier 130.
[0045] A drain pan receiving portion 152 is formed on the main body base 150. That is, the
drain pan receiving portion 152 is formed extending upward from a portion near a right
end of the main body base 150. A drain pan that will be described later is received
in the drain pan receiving portion 152.
[0046] The drain pan receiving portion 152 is provided with a plurality of insertion holes
154, 156, and 158. The insertion holes 154, 156, and 158 are portions in which a plurality
of water guide members 206, 216, 222', 224', and 226' formed on lower ends of the
heat exchangers 200, 210, and 220 are inserted.
[0047] In more detail, the side insertion holes 154 are formed on a right top surface of
the drain pan receiving portion 152. The side water guide members 222, 224', and 226'
are inserted in the respective sideward insertion holes 154. The side insertion holes
154 include first, second, and third insertion holes 154a, 154b, and 154c. The first,
second, and third water guide members 222', 224', 226' are respectively inserted in
the first, second, and third insertion holes 154a, 154b, and 154c.
[0048] The front insertion hole 156 is formed at the left side of the side insertion hole
154. The front water guide member 216 of the front heat exchanger 210 is inserted
in the front insertion hole 156.
[0049] The inner insertion hole 158 is further formed at the left side of the front insertion
hole 156. That is, the drain pan receiving portion 152 is stepped such that the left
side is relatively lower than the right side. The inner insertion hole 158 is formed
on the left side of the drain pan receiving portion 152. The inner water guide member
206 of the inner heat exchanger is inserted in the inner insertion hole 158.
[0050] A recovery assembly 160 is mounted on the front surface of the barrier 130. That
is, the recovery assembly 160 is inserted from a front side into the recovery receiving
portion 144 formed near the upper end of the barrier 130.
[0051] The recovery assembly 160 is enclosed by the case. Although not shown in the drawings,
the recovery assembly 160 includes a recovery fan and a recovery motor. A recovery
inlet 162 is formed on a front surface of the recovery assembly 160 and a recovery
outlet 164 is formed on the left side.
[0052] The recovery inlet 162 is formed in a circular shape corresponding to the inner outlet
204 formed on the inner heat exchanger. The recovery outlet 164 is formed extending
left-downward from the recovery assembly 160. The recovery outlet 164 is formed in
a rectangular pillar shape.
[0053] A fan-shaped heater assembly 170 is mounted on the front surface of the barrier 130.
The heater assembly 170 functions to heat the circulation air circulating along the
heat exchangers 200, 210, and 220. Accordingly, the heater assembly includes a heater
(not shown) that generates hot air using electricity fed from the external side. The
circulation air heated by the heater assembly 170 is fed to the adsorption member
182 to vaporize the moisture adsorbed in the adsorption member 182.
[0054] A heater outlet 172 is formed on the front surface of the heater assembly 170. A
heater inlet 174 is formed on the rear surface of the heater assembly 170. The heater
outlet 172 is a portion through which the high temperature circulation air, which
is heated while passing through the heater assembly, is discharged frontward of the
heater assembly 170. The heater inlet 174 is a portion to which the recovery outlet
164 of the recovery assembly 160 is coupled. The heater outlet 172 is formed in a
fan-shape.
[0055] An adsorption motor 176 is mounted on a rear side of the right end of the heater
assembly 170. The adsorption motor 176 provides rotational force to the adsorption
assembly 180 and is received in the adsorption motor receiving portion 138 of the
barrier 130. An adsorption shaft 176' that is a rotational shaft of the adsorption
motor 176 is installed to project frontward after passing through the right end of
the heater assembly 170. Accordingly, the adsorption assembly 180 is fixed on the
front end of the adsorption shaft 176'.
[0056] The adsorption assembly 180 is installed in front of the barrier 130. The adsorption
assembly 180 includes an adsorption member 182 for adsorbing the moisture contained
in the air and an adsorption case 184 for fixing and supporting the adsorption member
182.
[0057] The adsorption member 182 may be formed of paper. That is, the adsorption member
182 is formed in a circular shape as a whole. An internal structure is formed in a
honeycomb shape such that a plurality of through holes are horizontally formed.
[0058] In more detail, the adsorption member 182 is formed by rolling a two-layer paper
in a honeycomb shape so that the through holes can be formed. Subsequently, the rolled
paper is dipped in the adsorption solution so that the adsorption solution is applied
on a surface of the rolled paper. As described above, since the adsorption solution
is applied on the surface of the adsorption member 182, the moisture contained in
the air is adsorbed in the adsorption member 182 and thus the moisture is removed
from the air.
[0059] The adsorption case 184 includes an edge portion 184a enclosing the outer portion
of the circular adsorption member 182, a central portion 184b supporting a central
portion of the adsorption member 182, and a plurality of connecting portions 184c
connecting the edge portion 184a to the central portion 184b.
[0060] A front end of the adsorption shaft 176' of the adsorption motor 176 is fixedly connected
to the central portion 184b. Therefore, the adsorption case 184 and the adsorption
member 182 can rotate with a constant speed in accordance with a torque of the adsorption
motor 176.
[0061] The adsorption member 182 and the adsorption case 184 are fixedly mounted on the
front surface of the barrier 130 by the adsorption frame 190. The adsorption frame
190 is fixed on the front surface of the barrier 130 by, for example, a screw, in
a state where it receives the adsorption member 182 and the adsorption case 184.
[0062] A hot air guide 192 is formed on a left portion of the adsorption frame 190. The
hot air guide 192 is formed in a fan-shape corresponding to the heater assembly 170.
The hot air guide 192 protrudes frontward from the front surface of the adsorption
frame 190.
[0063] The hot air guide 192 functions to guide the circulation air, which is heated while
passing through the heater assembly 170, to the front heater exchanger 210. Therefore,
the hot air guide 192 is opened rearward so that the circulation air can be introduced
therein. The hot air guide 192 has an opened right side and an opened lower end so
that the heated circulation air can be introduced into a front air inlet 212 of the
front heat exchanger 210.
[0064] Sealing members 194 are respectively provided on upper and lower ends of the hot
air guide 192. That is, the sealing members 194 are formed of an elastic material
such as rubber and provided on respective rear surface of the upper and lower ends
of the hot air guide 192.
[0065] The sealing member 194 functions to block a gap defined between the adsorption frame
190 and the adsorption member 182. Therefore, the high temperature circulation air
flowing through the hot air guide 192 is not leaked through the gap defined between
the adsorption frame 190 and the adsorption member 182.
[0066] The inner heat exchanger 200 is installed on the barrier 130. That is, the inner
heat exchanger 200 is vertically installed on a right portion of the rearward recess
of the barrier 130. The inner heat exchanger 200 allows the circulation air in the
inner heat exchanger 200 and the air flowing rearward through the central through
hole 134 to heat-exchange with each other. The inner heat exchanger 200 is provided
with a plurality of air through holes provided in the form of slits.
[0067] The inner heat exchanger 200 is provided at a rear surface with inner inlet 202 and
inner outlet 204 through which the air is introduced and discharged.
[0068] The inner inlet 202 is formed on a rear-lower end of the inner heat exchanger 200.
The inner inlet 202 is coupled to the air outlet formed on the barrier 130. Accordingly,
the inner inlet 202 has a corresponding size to the air outlet 146. The circulation
air discharged through the air outlet 146 is guided into the inner heat exchanger
200 through the inner inlet 202.
[0069] The inner outlet 204 is formed on a rear-upper end of the inner heat exchanger 200.
The inner outlet 204 allows the circulation air in the inner heater exchanger 200
to be introduced through the recovery inlet 162 of the recovery assembly 160. Accordingly,
the inner inlet 204 is coupled to the recovery inlet while having a corresponding
size and shape to the recovery inlet 162.
[0070] An inner water guide member 206 is further formed on a lower end of the inner heat
exchanger 200. That is, the inner water guide member 206 formed in a thin cylindrical
shape is formed extending downward from the lower end right side of the inner heat
exchanger 200. The outer diameter of the inner water guide member 206 has a corresponding
side to an outer diameter of the inner insertion hole 158 of the drain receiving portion
152. Therefore, the inner water guide member 206 is inserted and mounted in the inner
insertion hole 158.
[0071] The front heat exchanger 210 is further installed in front of the barrier 130. The
front heat exchanger 210 is installed in front of the adsorption frame 190 to enclose
the right side of the adsorption frame 190. Accordingly, the external air introduced
into the adsorption assembly 180 heat-exchanges while passing through the front heat
exchanger 210.
[0072] The front heat exchanger 210 is bent rearward at its right end so that it has a ┘
-shape when viewed from a top. A plurality of air passing hole provided in the form
of slits are formed on left and right sides of the front heat exchanger.
[0073] A left central portion of the front heat exchanger 210 is partly recessed rightward.
The front inlet 212 is formed through the left central portion of the front heat exchanger
210. The front inlet 212 corresponds to right and lower ends of the hot air guide
192. Therefore, the front inlet 212 closely contacts the right and lower ends of the
hot air guide 192 of the adsorption frame 190 so that the circulation air heated by
the hot air guide 192 is guided into the front heat exchanger 210.
[0074] A front outlet 214 is formed on a right upper end of the front heat exchanger 210.
That is, a right end of the front heat exchanger 210 is bent rearward. The front outlet
214 is formed on a right side upper end of the bent portion of the front heat exchanger
210. The circulation air introduced into the front heat exchanger 210 through the
front inlet 212 is discharged through the front outlet 214. The air discharged through
the front outlet 214 is introduced into the side heat exchanger 220.
[0075] A front water guide member 216 is formed extending downward from a right-lower end
of the front heat exchanger 210. The front water guide member 216 functions to guide
the condensed water generated in the front heat exchanger 210 downward. The front
water guide member 216 is inserted in the front insertion hole 156 of the drain pan
receiving portion 152. Accordingly, the front water guide member 216 is formed in
a thin cylindrical shape having an outer diameter corresponding to an inner diameter
of the front insertion hole 156.
[0076] The side heat exchanger 220 is installed on a front-right portion of the barrier
130. That is, the side heat exchanger 220 is installed at the right side of the front
heat exchanger 210. Like the inner and front heat exchangers 220 and 200, the side
heat exchanger 220 functions to allow the interior and exterior airs to heat-exchange
with each other.
[0077] The side heat exchanger 220 is a portion at which the air introduced through the
inlet 128 of the right panel 116 primarily heat-exchanges. The side heat exchanger
220 includes three heat exchange units. That is, the side heat exchanger 220 includes
first, second, and third heat exchange units 222, 224, and 226 that are vertically
installed in a line.
[0078] The first heat exchange unit 222 is a portion where the external air introduced through
the air inlet 128 heat-exchanges primarily. As shown in the drawing, the first heat
exchange unit 222 is formed in a rectangular shape and provided at a left side rear-lower
end with a first outlet 222a.
[0079] The first outlet 222a is a portion through which the circulation air is discharged.
The circulation air discharged through the first outlet 222a is introduced through
the air inlet 146' of the barrier 130. Accordingly, the first outlet 222a is coupled
to the air inlet 146' while having a corresponding size and shape to the air inlet
146'.
[0080] A first inlet 222b is formed on a front end upper portion of a left side of the first
heat exchange unit 222. That is, the first inlet 222b is formed diagonally with respect
to the first outlet 222a. The first inlet 222b functions as an inlet through which
the circulation air is introduced into the first heat exchange unit 222.
[0081] The second heat exchange unit 224 is provided at a left side of the first exchange
unit 222. The air passing through the first heat exchange unit 222 further heat-exchanges
at the second heat exchange unit 224. A second outlet 224a is formed on an upper-front
end of the right side of the second heat exchange unit 224.
[0082] The circulation air in the second heat exchange unit 224 is discharged through the
second outlet 224a. The second outlet 224a is coupled to the first inlet 222b while
having a corresponding size to the first inlet 222b. Therefore, the circulation air
discharged through the second outlet 224a is introduced into the first heat exchange
unit 222 through the first inlet 222b.
[0083] A second inlet 224b is formed on a rear-upper end of a left side of the second heat
exchange unit 224. The second inlet 224b is formed to correspond to a third outlet
226a to allow the circulation air to be introduced into the second heat exchange unit
224.
[0084] The third heat exchange unit 226 is provided at a left side of the second heat exchange
unit 224. The air passing through the first and second heat exchange units 222 and
224 heat-exchanges thirdly at the third heat exchange unit 226. The third heat exchange
unit 226 has a shape corresponding to the second heat exchange unit 224 and is provided
at a rear-upper end of a left side with a third outlet 226a.
[0085] The third outlet 226a has a corresponding size and shape to the second inlet 224b
and is coupled thereto. Accordingly, the circulation air discharged through the third
outlet 226a is introduced into the second heat exchange unit 224 through the second
inlet 224b.
[0086] A third inlet 226b is formed on a front upper end of a left side of the third heat
exchange unit 226. The third inlet 226b is a portion through which the circulation
air is introduced into the third heat exchange unit 226. The third inlet 226b has
a corresponding shape and size to the front outlet 214 of the front heat exchanger
210 and is coupled thereto.
[0087] Side water guide members 222', 224' and 226' that are formed in a thin cylindrical
shape are respectively formed extending downward from the respective first, second,
and third heat exchange units 222, 224, and 226. That is, the first, second, and third
heat exchange units 222, 224, and 226 are respectively provided at front-lower ends
with the side water guide members 222', 224', and 226' extending downward by a predetermined
length.
[0088] The side water guide members 222', 224', and 226' are provided to guide the condensed
water in the side heat exchanger 220 downward. The side water guide members 222',
224', and 226' are respectively inserted in the side insertion holes 154 formed thorough
the drain pan receiving portion 152 of the main body base 150. Therefore, outer diameters
of the side water guide members 222', 224', and 226' correspond to the respective
diameters of the first, second, and third insertion holes 154a, 154b, and 154c.
[0089] The side water guide members 222', 224', and 226' are respectively referred to as
first, second, and third side water guide members. The first side water guide member
222' is formed extending downward from the lower end of the first heat exchange unit
222 and inserted in the first insertion holes 154a. The second side water guide member
224' is formed extending downward from the lower end of the second heat exchange unit
224 and inserted in the second insertion hole 154b. The third water guide member 226'
is formed extending downward from the lower end of the third heat exchange unit 226
and inserted in the third insertion hole 154c.
[0090] A shielding plate 230 for dividing the space in front of the barrier into upper and
lower spaces is provided. The shielding plate 230 is formed with a flat plate to divide
the front space of the barrier into the upper and lower spaces.
[0091] The shielding plate 130 blocks a gap between the front panel 112 and the barrier
130 and a gap between the right panel 116 and the barrier 130 so as to prevent the
intake air from being mixed with the exhaust air. That is, the shielding plate 130
functions to prevent the external air introduced through the air inlet 128 from being
mixed with the air discharged to the external side (indoor space) through the air
outlet 122.
[0092] A blower motor 240 is installed in rear of the barrier 130. The blower motor 240
provides torque to the blower fan 246 using electricity supplied from the external
side. The blower motor 240 is installed on a rear side of the motor support 136 of
the barrier 130. The blower motor 240 is provided with a motor shaft 242 transmitting
the torque and extending rearward.
[0093] The blower motor 240 is supported by a motor mount 244. That is, the cylindrical
blower motor 240 is fixed on a rear side of the barrier 130 by the motor mount 244.
The motor mount 244 is formed to enclose the blower motor 240 and fixed on the rear
surface of the barrier 130 by, for example, a screw. Accordingly, the blower motor
240 is fixed on the rear side of the barrier 130 in a state where it is received in
the motor mount 244.
[0094] A blower fan 246 is installed on an outer portion of the blower motor 240. The blower
fan rotates by the torque of the blower motor 240 to forcedly generate an air current.
That is, the blower fan is mounted on a rear end of the motor shaft 242 protruding
rearward of the blower motor 240 and is rotated together with the rotation of the
motor shaft 242.
[0095] The drain pan 250 is received in the lower portion of the drain pan receiving portion
152. The drain pan 250 temporally collects the condensed water falling through the
water guide members 206, 216, 222', 224', and 226'. The drain pan has a corresponding
shape to the drain pan receiving portion 152.
[0096] The drain pan 250 is provided with a drain hole 252 through which the collected water
is drained to the water tank 300. The drain hole 252 is selectively opened by a drain
unit 254.
[0097] The drain unit 254 is provided in the form of a cantilever to open the drain hole
252 when the water tank 300 is installed on the support 310 and to close the drain
hole 252 when the water tank 300 is not installed on the support 310. The following
will describe the drain unit 254 in more detail.
[0098] The water tank 300 and the support 310 are provided under the main body base 150.
[0099] The water tank 300 stores the water (condensed water) generated in the heat exchangers
200, 210, and 220. That is, the water drops condensed in the heat exchangers 200,
210, and 220 fall into the water tank 300 through the drain pan 250 and are stored
therein.
[0100] The water tank 300 is installed between front and rear supporting portions 314' and
314" of the support 310. The water tank 300 is installed to be taken out sideward
(leftward or rightward). The water tank 300 is formed in a rectangular box shape having
an opened top.
[0101] The support 310 is provided to support the main body 100, including the support base
312 and the supporting portion 314. The support base 312 is a portion that directly
contacts a floor of a building. The support base 312 is formed in a rectangular flat
plate.
[0102] The supporting portion 314 includes a front end supporting portion 314' protruding
upward from a front end of the support base 312 and a rear end supporting portion
314" protruding upward from a rear end of the support base 312.
[0103] The drain pan 250 is provided on the upper end of the support 310. That is, the drain
pan 250 is provided on the right end of the front end supporting portion 314' to guide
the water discharged from the heat exchangers 200, 210, and 220 to the water tank
300.
[0104] That is, the water falling from the water guide members 206, 216, 222', 224' and
226' formed on the lower end of the heat exchangers 200, 21, and 220 are collected
in the drain pan 250 and subsequently falls to the water tank 300.
[0105] Fig. 8 shows the barrier 130 in detail.
[0106] Referring to Fig. 8, coupling guides 320 and 322 for fixing the side heat exchanger
220 are horizontally formed on front-upper and front-lower ends of the right extending
portion 130b of the barrier 130. That is, the upper coupling guide 320 is horizontally
formed near the upper end of the right extending portion 130b and the lower end coupling
guide 322 is horizontally formed near the lower end of the right extending portion
130b.
[0107] Upper and lower coupling grooves 320' and 322' are respectively formed on right surfaces
of the upper and lower coupling guides 320 and 322. Coupling members 334 and 336 that
will be described below are respectively inserted in the upper and lower end coupling
grooves 320' and 322'. Therefore, male threads with which screws can be engaged may
be formed on inner surfaces of the upper and lower coupling grooves 320' and 322".
[0108] Fig. 9 shows a state where the adsorption motor assembly 176 and the inner heat exchanger
200 are mounted on the barrier 130 of Fig. 8. That is, Fig. 9 illustrates a state
where the adsorption motor assembly 176 is inserted in the adsorption motor receiving
portion 138. The inner heat exchanger 200 is closely fixed on a right portion of the
rearward recess 132. The inner heat exchanger 200 is mounted on the rearward recess
132 of the barrier 130 by the screws.
[0109] Figs. 10, 11, and 12 illustrate the side heat exchanger 220 in more detail. That
is, Fig. 10 is a perspective view of the side heat exchanger of the dehumidifier according
to an embodiment of the present invention and Figs. 11 and 12 are respective first
and second side exploded perspective views of the side heat exchanger of Fig. 10.
[0110] As shown in the drawings, the first, second, and third heat exchangers 222, 224,
and 226 are coupled to each other by coupling units 340 and 342 that will be described
below. At least one of the first, second, and third heat exchangers 222 and 224, and
226 are fixedly mounted on the barrier 130.
[0111] In more detail, one of upper and lower ends of at least one of the first, second,
and third heat exchangers 222 and 224, and 226 are fixed to the barrier 130 by coupling
members 334 and 336 that will be described below. In Figs. 10, 11, and 12, a case
where one of the upper and lower ends of the first heat exchanger 222 is fixed on
the barrier 130 is illustrated by way of example.
[0112] As shown in the drawings, a rear-upper end of the first heat exchanger 22 extends
upward to form the upper end coupling portion 330 and a rear-lower end of the first
heat exchanger 222 extends downward to form the lower end coupling portion 332.
[0113] The upper end coupling portion 330 is provided with an upper end through hole 330'
and the lower end coupling portion 332 is provided with a lower end through hole 332'.
The upper end through hole 330' and the lower end through hole 332' are holes in which
the coupling members 334 and 336 will be inserted.
[0114] The side heat exchanger 220 is fixedly mounted on the barrier 130 by the coupling
member 334 and 336. That is, the coupling members 334 and 336 that are screws fix
the side heat exchanger 220 on the barrier 130. However, the coupling members 334
and 336 are not limited to the screw. Other types of coupling members may be used.
[0115] The upper end coupling member 334 is inserted in the upper end coupling groove 320'
and the lower end coupling member 336 is inserted in the lower coupling groove 322'.
The upper and lower coupling members 334 and 336 pass respectively through the upper
and lower end through holes 330' and 332' of the first heat exchanger 222 and are
coupled to the upper and lower coupling grooves 320' and 322'.
[0116] Meanwhile, the first, second, and third heat exchangers 222, 224, and 226 are coupled
to each other by the coupling units 340 and 342.
[0117] The coupling units 340 and 342 include a coupling projection 340 and a projection
coupling groove 342 that are correspondingly formed to one surfaces of the heat exchangers
222, 224, and 226 and coupled to each other. That is, the projection coupling groove
342 and the coupling projection 340 are respectively formed on a left surface of the
first heat exchanger 222 and a right surface of the second heat exchanger 342 and
coupled to each other. The projection coupling groove 342 and the coupling projection
340 are respectively formed on a left surface of the second heat exchanger 224 and
a right surface of the third heat exchanger 226. Further, the projection coupling
groove 342 and the coupling projection 340 are respectively formed on corners of surfaces
of the respective heat exchangers 222, 224, and 226.
[0118] In more detail, the projection coupling grooves 342 are formed extending leftward
from a rear0upper end of the left surface of the first heat exchanger 222. The projection
coupling groove 342 is formed in a thin cylindrical shape. Therefore, the coupling
projections 340 are snap-fitted in the projection coupling grooves 342.
[0119] Therefore, an inner diameter of the projection coupling groove 342 may be equal to
or slightly less than an outer diameter of the coupling projection 340.
[0120] The projection coupling grooves 342 are formed extending leftward from a front-lower
end of the left surface of the first heat exchanger 222. This projection coupling
grooves 342 have an identical structure to those formed on the first heat exchanger
222.
[0121] The projection coupling groove 342s are further formed extending leftward from a
rear side of the left surface of the first heat exchanger 222. That is, the projection
coupling grooves 342 are formed above the first outlet 222a. On the other hand, the
projection coupling groove 342 is not formed on an upper end of the left surface of
the first heat exchanger 222 since the first inlet 222b formed on the front-upper
end of the left surface of the first heat exchanger 222 functions as a coupling unit
that is coupled to the second outlet 224a formed on the right surface of the second
heat exchanger 224.
[0122] The coupling projections 340 are formed extending rightward from corners of the right
surface of the second heat exchanger 224. As shown in the drawing, the coupling projections
340 are formed in a circular pillar shape and formed to correspond to the projection
coupling grooves 342 formed on the left surface of the first heat exchanger 222. That
is, the coupling projections 340 are formed on a rear-upper and, a rear-lower end,
and a front-lower end of the right surface of the second heat exchanger 224.
[0123] The projection coupling grooves 342 are formed on respective corners of the left
surface of the second heat exchanger. That is, the projection coupling grooves 342
are formed on front-lower end, front-upper end, and a rear-lower end of the left surface
of the second heat exchanger 224.
[0124] No projection coupling groove 342 is formed on a rear upper end of the left surface
of the second heat exchanger 224 since the second inlet 224b functions as the coupling
unit that is coupled to the third outlet 226a of the third heat exchanger 226.
[0125] The coupling projections 340 are formed on respective corners of the right surface
of the third heat exchanger. The coupling projections 340 formed on the right surface
of the third heat exchanger 226 are formed to correspond to the projection coupling
grooves 342 formed on the left surface of the second heat exchanger 224.
[0126] Figs. 13 and 14 illustrate the drain pan in more detail.
[0127] As described above, the drain pan 250 is provided with a drain pipe 252 extending
rearward from a rear surface. The drain pipe 252 guides the condensed water stored
in the drain pan 250 to the water tank 300. The drain pipe 252 is selectively opened
and closed by the drain unit 254. The drain pipe 252 is formed of a thin pipe and
a rear end of the drain pipe 252 is selectively closed by the drain unit 254.
[0128] The drain unit 254 includes a closing cap 254a for selectively closing the rear end
of the drain pipe 252, a drain lever 254b controlling the movement of the drain cap
254a, a hinge shaft 254c functioning as a central axis of the drain lever 254b, a
contact projection 254b selectively contacting the water tank 300, and a return spring
254e applying torque in a direction to the drain lever 254b.
[0129] The drain cap 254a is formed in a circular shape having a size corresponding to a
rear end of the drain pipe 252. The drain cap 254a is formed of an elastic material
such as rubber. Therefore, when the water tank 300 is separated from the support 310,
the drain cap 254a closely contacts the rear end of the drain pipe 252.
[0130] The drain lever 254b is formed in a 0-shape when viewed from top. The drain cap 254a
is installed on a left surface of the rear end (in Fig. 13) of the drain lever 254b
and the contact projection 254d is formed extending downward from a lower portion
of the right end of the drain lever 254.
[0131] The hinge shaft 254c is integrally formed on a central portion of the drain lever
254b formed in the □-shaped to function as a rotational shaft of the drain lever 254b.
The upper and lower ends of the hinge shaft 254c are rotatably mounted on a hinge
guide 254f formed extending rearward from a rear surface of the drain pan 250.
[0132] The contact projection 254d is formed in a cylindrical shape and selectively contacts
an upper edge of the water tank 300. That is, the contact projection 254d moves while
contracting a front end of the edge of the water tank 300 to rotate clockwise when
viewed from the top.
[0133] The return spring 254e is a spring for returning the contact projection 254d. That
is, after the contact projection 254d rotates clockwise by being pushed by the edge
of the water tank 300 and the water tank 300 is removed from the support 310, the
return spring applies torque to the contact projections such that the contact projection
254d rotates counterclockwise (when viewed from the top) to return to a state shown
in Fig. 13.
[0134] Fig. 15 is a schematic view of an air flow state in rear of a barrier of the humidifier
according to an embodiment of the present invention, Fig. 16 is a view illustrating
a circulation air flow path in Fig. 2, and Fig. 11 is a view illustrating a circulation
air flow path in Fig. 2.
[0135] An operation of the above-described dehumidifier of the present invention will be
described hereinafter with reference to Figs. 15 through 18.
[0136] Referring first to Fig. 15, external air is introduced into the dehumidifier through
a side surface (right surface) of the dehumidifier. The air dehumidified in the dehumidifier
is discharged to the external side (indoor space) through an upper end of the dehumidifier.
That is, the dehumidified air is discharged through the gap between the top panel
120 and other panels.
[0137] In more detail, when the blower motor 240 is driven, the blower fan 246 rotates by
the torque of the blower motor 240.
[0138] When the adsorption motor assembly 176 is driven, the adsorption assembly 180 rotates
by the torque of the adsorption motor 176 and thus the recovery fan (not shown) provided
in the recovery assembly 180 also rotates to generate a current of the circulation
air. At this point, the torque generated by the adsorption motor 176 is lower than
the torque generated by the recovery motor or the blower motor 240. Therefore, the
adsorption assembly 180 rotates with a relatively low RPM.
[0139] At this same time, the heater (not shown) provided in the heater assembly is driven
by the external power to heat the air.
[0140] Meanwhile, as the blower fan 246 rotates, sucking force is generated in the dehumidifier
and thus the external air (air in the indoor space) is introduced into the main body
case 110 through the air inlet 128 of the right panel 116 (see ① in Fig. 15).
[0141] The external air introduced into the main body case 110 passes through the side heat
exchanger 220 as indicated by ② in Fig. 15. That is, the air passes successively through
the air passing holes provided in the form of slits on the first, second, and third
heat exchange units 222, 224, 226.
[0142] At this point, the air outside of the side heat exchanger 220 is heat-exchanged with
the air inside of the side heat exchanger 220. Accordingly, a temperature of the air
outside of the side heat exchanger 220 increases by the hot circulation air in the
side heat exchanger 220.
[0143] The air passing through the side heat exchanger 220 passes through the front heat
exchanger 210 as shown in Fig. 15. That is, the external air flows from the right
and front sides of the front heat exchanger 210 to the rear side of the front heat
exchanger 210. At this point, the airs inside and outside of the front heat exchanger
210 are heat-exchanged with each other.
[0144] The air passing through the front heat exchanger 210 passes through the adsorption
member 182 as indicated by ④ in Fig. 15. Therefore, the moisture contained in the
air is adsorbed in a surface of the adsorption member 182. Therefore, the air becomes
more dry air.
[0145] The external air passing through the adsorption assembly 180 passes through the inner
heat exchanger 200 as indicated by ⑤ of Fig. 15. Likewise, the airs inside and outside
of the inner heat exchanger 200 are heat-exchanged with each other and thus a temperature
of the air is further increased.
[0146] The air passing through the inner heat exchanger 200 flows to the rear side of the
barrier 130 through the central through hole 134 of the barrier 130 as indicated by
⑥ of Fig. 15. The air directed to the rear side of the barrier is discharged in a
radial direction by the blower fan 246 and guide by the airflow guide 148.
[0147] The airflow guide 148 encloses the outer side of the blower fan 246 and has a left
end extending upward. Thus, the air discharged by the blower fan 246 flows toward
the left upper portion of the barrier 130 as indicated by ⑦ of Fig. 15.
[0148] Describing the airflow state by the airflow guide 148 in more detail with reference
to Fig. 16, the air discharged in the circumferential direction by the blower fan
246 is guided by the circular guide portion 148" and directed leftward (rightward
in Fig. 16) as indicated by (7a).
[0149] Subsequently, the air flows upward by the upward guide portion 148", and as indicated
by (7b), the air passes through the gap between the upper end of the upward guide
portion 148" and the left panel 118.
[0150] The air passing through the gap between the upper end of the upward guide portion
148" and the left panel 118 is partly directed to a front side of the barrier 130
through the gap between the upper end of the barrier 130 and the top panel 120. That
is, since the gap is formed between the top panel 120 and the upper end of the barrier
130, as indicated by (7c), the air in rear of the barrier 130 flows toward the front
side of the barrier 130.
[0151] As described above, the air ascended by the airflow guide 148 flows to the front
side of the barrier 130. At this point, the shielding plate 230 in front of the barrier
130 blocks the downward flow of the air so that the air guided upward by the airflow
guide 148 cannot be introduced again into the adsorption assembly 180. That is, the
air direction upward by the airflow guide 148 flows to the lower side of the shielding
plate 230 so as not to be mixed with the air that is being introduced from the external
side.
[0152] The air directed upward is dispersed toward the edge of the top panel 120 and discharged
through the air outlet 122. That is, as indicated by ⑧ of Fig. 15, the air is discharged
to the external side through the air outlet 122 defined by the gap between the top
panel and the main body case 110. The method for discharging the air through the air
outlet 122 defined by the gap provided in the form of slits is called a line diffuser
method.
[0153] The flow of the circulation air in the heat exchangers 200, 210, and 220 will now
be described with reference to Figs. 17 and 18.
[0154] The circulation air path formed along the heat exchangers 200, 210, and 220 is formed
in a closed circuit. That is, unlike the above-described air (i.e., air introduced
from the indoor space to the dehumidifier), the circulation air in the heat exchangers
200, 210, and 220 is not replaced but continuously circulate along a closed fluid
path to heat-exchange with the external air.
[0155] Describing in more detail, the circulation air directed from the recovery assembly
160 is, as indicated by □, introduced into the heater assembly 170 through the heater
inlet 174 connected to the recovery outlet 164.
[0156] The circulation air introduced into the heater assembly 170 is heated by a heater
(not shown) and directed frontward as indicated by □ through the heater outlet 172.
The circulation air directed frontward through the heater outlet 172 passes through
the adsorption member 182. At this point, the high temperature circulation air discharged
through the heater outlet 172 vaporizes the moisture adsorbed in the adsorption member
182.
[0157] That is, as the adsorption member 182 rotates with a low RPM by the adsorption motor
176, the moisture contained in the air passing through the adsorption member 182 is
adsorbed in the adsorption member 182. At this point, as the high temperature circulation
air passes through the adsorption member 182 as described above, the moisture adsorbed
in the adsorption member 182 is vaporized and thus removed from the adsorption member
182.
[0158] In addition, since the heater outlet 172 is formed in the fan-shape, the adsorption
member 182 affected by the high temperature circulation air discharged through the
heater outlet 172 becomes a range (fan-shape) corresponding to the heat outlet 172.
However, since the adsorption member 182 keeps rotating with the low RPM by the adsorption
motor 176, the adsorption member 182 entirely contacts the high temperature circulation
air discharged through the heater outlet 172 when a predetermined time has elapsed.
[0159] The circulation air passing through the adsorption member 182 is introduced into
the hot air guide 192 of the adsorption frame 190 and subsequently directed into the
front heat exchanger 210 through the front air inlet 212 of the front heat exchanger
210 as indicated by □.
[0160] The circulation air directed into the front heat exchanger 210 is heat-exchanged
with the external air. That is, as described above, the circulation air is heat-exchanged
with the external air which is introduced through the air inlet 128 and flows along
an external side of the front heat exchanger 210.
[0161] In more detail, since the circulation air in the front heat exchanger 210 is higher
in a temperature than the external air, the external air flowing along an outer side
of the front heat exchanger 210 takes the heat of the circulation air in the front
heat exchanger 210. Therefore, the temperature of the circulation air in the front
heat exchanger 210 is lowered and thus the moisture contained in the circulation air
is condensed and flows downward.
[0162] The circulation air passing through the front heat exchanger 210 is, as indicated
by □, introduced into the side heat exchanger 220. That is, the circulation air in
the front heat exchanger 210 is directed to the third heat exchange unit 226 through
the front outlet 214 and subsequently introduced into the third heat exchanger 226
through the third inlet 226b. Subsequently, the circulation air passes through the
second heat exchanger 224 and then to the first exchange unit. At this point, the
external air outside of the side heat exchanger 220 takes the heat from the circulation
air and thus the moisture contained in the circulation air is condensed.
[0163] The air passing through the side heat exchanger 220 is introduced into the inner
heat exchanger 200. In more detail, the circulation air discharged through the first
outlet 222a of the first heat exchanger 222 is, as indicated by □, introduced into
the barrier through the air inlet 146' formed through the barrier 130. The circulation
air is, as indicated by □, introduced into the inner heat exchanger 200 through the
air outlet 146 and the inner inlet 202.
[0164] Like the side and front heat exchangers 220 and 210, the circulation air introduced
into the inner heat exchanger 200 is heat-exchanged with the external air. That is,
after passing through the adsorption member 182, the circulation air is heat-exchanged
with the air directed to a rear side of the barrier through the central through hole
134 of the barrier 130.
[0165] Accordingly, the circulation air in the inner heat exchanger 200 is cooled and thus
the moisture contained in the circulation air is condensed and discharged downward.
[0166] The circulation air passing through the inner heat exchanger 200 is, as indicated
by □, introduced into the recovery assembly 160. That is, since the inner inlet 204
of the inner heat exchanger 200 is coupled to the recovery inlet 162 of the recovery
assembly 160, the circulation air in the inner heat exchanger 200 is introduced into
the recovery assembly 160.
[0167] The circulation air introduced into the recovery assembly 160 is forcedly directed
by the recovery fan (not shown) into the heater assembly 170 through the recovery
outlet 164 as indicated by □.
[0168] Through the above-described process, the circulation air circulates along the closed
flow path in which the heat exchangers 200, 210, and 220 are arranged, thereby completing
one cycle.
[0169] The condensed water generated by the heat exchange between the external air and the
circulation air must be removed frequently by the user.
[0170] Describing the above-described process in more detail, the condensed water generated
by the temperature difference in the heat exchangers 200, 210, and 220 falls down
along the inner walls of the heat exchangers 200, 210, and 220 and is collected in
the drain pan 250. That is, since the water guide members 206, 216, 222', 224', and
226' protruding downward are formed on the lower ends of the heat exchangers 200,
210, and 220 and communicate with the inside of the drain pan 250 by being inserted
in the insertion holes 154, 156, and 158 of the drain pan receiving portion 152, the
condensed water generated in the heat exchangers 200, 210, and 220 is collected in
the drain pan 250 through the water guide members 206, 216, 222', 224', ad 226'.
[0171] The condensed water collected in the drain pan 250 falls into the water tank 300.
That is, the condensed water that is temporarily collected in the drain pan 250 falls
into the water tank 300 through a hole formed through a side of the drain pan 250.
[0172] When a certain amount of condensed water is collected in the water tank 300 through
the above-described process, the user takes the water tank out in a side direction
and dumps out the water from the water tank.
[0173] Fig. 19 illustrates an operation state of the drain unit 254 provided in the drain
pan 250. That is, Fig. 19 shows a state where the drain pipe 252 is opened as the
water tank 300 is inserted into the support 310.
[0174] In more detail, when the water tank 300 is separated from the support 310, as shown
in Fig. 13, the drain pipe 252 is closed by the closing cap 254a. Therefore, the condensed
water falling through the water guide members 206, 216, 222', 224', and 226' of the
heat exchangers 200, 210, and 220 are collected in the drain pan 250.
[0175] Further, when the water tank 300 is inserted into the support 310 from the left side
of the support 310, this state is shown in Fig. 19. That is, from the state shown
in Fig. 13, the right end of the water tank 300 contacts the contact projection 254d.
At this point, since a corner portion of the right end of the water tank 300 is rounded,
the contact projection 254d slides along the edge of the water tank 300 to be positioned
on the front end edge of the water tank as shown in Fig. 19.
[0176] Then, the drain lever 254b rotates clockwise (when viewed from the top) as shown
in Fig. 19, and thus the closing cap 254a moves away from the rear end of the drain
pipe 252 to open the drain pipe 252. Accordingly, the condensed water collected in
the drain pan 250 falls to the water tank 300 through the drain pipe 252.
[0177] Next, when the water tank 300 is separated leftward from the support 310, the drain
lever 254b rotates counterclockwise by the rotational force of the return spring 254e
and thus the closing cap 254a closes the rear end of the drain pipe 252. Therefore,
the water collected in the drain pan 250 cannot be drained out through the drain pipe
252.
[0178] It will be apparent to those skilled in the art that various modifications and variations
can be made in the present invention. Thus, it is intended that the present invention
covers the modifications and variations of this invention provided they come within
the scope of the appended claims.
Industrial Applicability
[0179] The above-described dehumidifier is light while improving the dehumidifying efficiency
and making it easy to drain the condensed water. Therefore, the industrial applicability
of the present invention is very high.
