Technical
[0001] The disclosure relates to the field of dehumidifiers, more particularly to a method
and device for controlling drainage of a dehumidifier, and a dehumidifier.
Background
[0002] Condensed water produced during normal working of a dehumidifier is usually collected
in a water collecting device. A drainage mode commonly adopted by the water collecting
device refers to: directly draining water off by means of the water collecting device
or a continuous drainage port. The above-mentioned drainage mode cannot seriously
affect a user during normal use. However, when the dehumidifier is located at a low
place but water needs to be drained to a high place, the above-mentioned drainage
mode is not applicable. At present, in view of this, water is usually drained from
the low place to the high place by means of power generated by a power device.
[0003] The working principle of the power device built in the dehumidifier is that: water
obtained by dehumidification is collected in the water collecting device, when a water
level of the water collecting device reaches a certain height, the power device is
started, and water is drained by means of the power device; and when the water level
descends to a certain height, the power device stops working. According to this working
mode, the water level in the water collecting device needs to be detected. When detection
of the water level is abnormal, water is unlikely to drain off from the dehumidifier.
In addition, when the detection of the water level has errors, the detection of the
water level is inaccurate, which may cause incomplete drainage. The above-mentioned
situation is likely to make the dehumidifier faulty.
[0004] An effective solution has not been proposed yet currently for the problem that water
is unlikely to drain off from the dehumidifier in the related art.
Summary
[0005] The embodiments of the disclosure mainly aim to provide a method and device for controlling
drainage of a dehumidifier, and a dehumidifier, which are used to solve the problem

of the power device reaches a fourth preset period, the power device to stop operating;
recording the number of operating times of the power device under the preset working
mode; judging whether the number of the operating times reaches a preset value or
not; and returning, when it is determined that the number of the operating times does
not reach the preset value, to execute a step of detecting the stopping period when
the power device stops operating.
[0009] In an example embodiment, when it is determined that the number of the operating
times reaches the preset value, the method for controlling the drainage further comprising:
returning to execute a step of detecting whether the compressor operates or not, and
zeroing the number of the operating times under the preset working mode.
[0010] In an example embodiment, the fourth preset period and the second preset period have
a same duration, the preset value is determined in a following mode: detecting humidity
of an environment where the dehumidifier is located; and determining the preset value
according to the humidity.
[0011] To this end, according to an embodiment of the disclosure, a device for controlling
drainage of a dehumidifier is provided, comprising: a first detecting element, configured
to detect, when a compressor of the dehumidifier is powered on, whether the compressor
operates or not; a first controlling element, configured to control, when it is detected
that the compressor stops operating, a power device of the dehumidifier to start draining
water off after a first preset period; a second detecting element, configured to detect
an operation period of the power device; a first judging element, configured to judge
whether the operation period reaches a second preset period or not; and a second controlling
element, configured to control, when it is determined that the operation period reaches

to control, when it is detected that the compressor does not start operating, the
dehumidifier to enter a state of being powered off.
[0013] In an example embodiment, the third controlling element comprises: a detecting component,
configured to detect a stopping period when the power device stops operating, wherein
the stopping period is a period within which the power device stops operating; a first
judging component, configured to judge whether the stopping period reaches a third
preset period or not; a first controlling component, configured to control, when it
is determined that the stopping period reaches the third preset period, the power
device to start draining water off; a second controlling component, configured to

the preset value, the stopping period when the power device stops operating.
[0014] In an example embodiment, the first detecting element is further configured to detect,
when it is determined that the number of the operating times reaches the preset value,
whether the compressor operates or not, and zero the number of the operating times
under the preset working mode.
[0015] In an example embodiment, the fourth preset period and the second preset period have

of the dehumidifier is powered on, whether the compressor operates or not, control,
when it is detected that the compressor stops operating, the power device to start
draining water off after the first preset period, and control the power device to
stop operating after the second preset period.
[0017] According to the embodiments of the disclosure, when the compressor of the dehumidifier
is powered on, it is detected whether the compressor operates or not. When it is detected
that the compressor stops operating, the power device of the dehumidifier is controlled
to start draining water off after the first preset period. When drainage time of the
power device reaches the second preset period, the power device is controlled to stop
operating, i.e., to stop draining water off. In such a way, by controlling the starting
time and stopping period of the power device by means of time, the problem that water
cannot be drained from the dehumidifier due to abnormal water level detection is solved,
thereby achieving the effect of controlling the dehumidifier to drain water off by
means of time instead of water level detection.

Detailed description of the embodiments
[0019] It is important to note that the embodiments in the application and the characteristics

embodiments in detail.
[0020] In order to make those skilled in the art better understand the solutions of the

[0021] It is important to note that the specification and claims of the disclosure and terms
'first', 'second' and the like in the above-mentioned drawings are used to distinguish
similar objects, and do not need to describe a specific sequence or a precedence order.
It will be appreciated that data used in such a way may be exchanged under appropriate
conditions, in order that the embodiments of the disclosure described herein can be
implemented in a sequence other than sequences graphically shown or described here.
In addition, terms 'include' and 'have' and any inflexions thereof are intended to
cover non-exclusive inclusions. For instance, it is not limited for processes, methods,
systems, products or devices containing a series of steps or units to clearly list
those steps or units, and other steps or units which are not clearly listed or are
inherent to these processes, methods, products or devices may be included instead.
[0022] The embodiments of the disclosure provide a method for controlling drainage of a
dehumidifier. The method may be used for controlling the dehumidifier to drain water
off. The dehumidifier may include a compressor, a power device, a water collecting
device, a controller, and other components, and may also include a timing device such
as a timer. Drainage control of the dehumidifier according to the embodiments of the
disclosure may be executed by means of the controller of the dehumidifier.
[0023] Fig. 1 is a flowchart of a method for controlling drainage of a dehumidifier according
to an embodiment of the disclosure. As shown in Fig. 1, the method for controlling
the drainage includes the following steps.
[0024] Step S102: When a compressor of a dehumidifier is powered on, it is detected whether
the compressor operates or not.
[0025] The compressor of the dehumidifier is powered on, i.e., the compressor is started.
Under this state, the compressor may be standby, i.e., the compressor is energized
but does not work, or the compressor may be in an operation state namely a dehumidification
working state. When the compressor is de-energized, it may be shown that the dehumidifier
does not execute a dehumidification operation. In this case, water may not be drained
off. When the compressor is energized, it is detected whether the compressor operates
or not. When the compressor operates, the dehumidifier is collecting, via a water
collecting device, water obtained by treating air by the compressor. When the compressor
stops operating, since the compressor is energized, it is shown that the compressor
may stop operating after dehumidification reaches a certain extent, and may be standby.
[0026] Step S104: when it is detected that the compressor stops operating, a power device
of the dehumidifier is controlled to start draining water off after a first preset
period.
when it is detected that the compressor stops operating, the power device is controlled
to start draining water off after the first preset period. Alternatively, when it
is detected that the compressor stops operating, i.e., the compressor is standby,
a controller controls a timer to start timing. When time measured by the timer reaches
the first preset period, the timer returns a timing reaching signal to the controller,
and after receiving the signal, the controller controls the power device to start
draining water off. Certainly, the control may also inquire the measured time of the
timer, and when it is inquired that the measured time reaches the first preset period,
the power device is controlled to start draining water off. Wherein, the first preset
period may be determined according to the model of the dehumidifier and environment
parameters.
[0027] Step S106: An operation period of the power device is detected.
[0028] After the power device starts draining water off, the controller detects the operation
period of the power device namely drainage time. The operation period may be started
by means of the timer after the power device starts operating.
[0029] Step S108: It is judged whether the operation period reaches a second preset period
or not.
[0030] Step S110: When it is determined that the operation period reaches the second preset
period, the power device is controlled to stop operating.
[0031] After the power device is started, it is unnecessary to be draining water off all
the time. Therefore, after the operation period of the power device is detected, it
is judged whether the operation period reaches the second preset period. When so,
the power device may be controlled to stop operating, thereby preventing the power
device from operating all the time to waste electric energy. If not, the power device
continuously operates. Wherein, the second preset period may be determined according
to the model of the dehumidifier, and may also be determined according to parameters
such as a drainage amount of the dehumidifier within unit time and a usual water collecting
amount in the water collecting device. When the operation period of the power device
reaches the second preset period, it is shown that water in the water collecting device
has been drained off or water drainage reaches a certain amount.
[0032] According to the embodiments of the disclosure, when the compressor of the dehumidifier
is powered on, it is detected whether the compressor operates or not. when it is detected
that the compressor stops operating, the power device of the dehumidifier is controlled
to start draining water off after the first preset period. When drainage time of the
power device reaches the second preset period, the power device is controlled to stop
operating, i.e., to stop draining water off. In such a way, by controlling the starting
time and stopping period of the power device by means of time, the problem that water
cannot be drained from the dehumidifier due to abnormal water level detection is solved,
thereby achieving the effect of controlling the dehumidifier to drain water off by
means of time instead of water level detection.
[0033] It is important to note that 'operate' and 'stop operating' of the compressor in
the embodiments of the disclosure occur when the compressor is energized.
[0034] Fig. 2 is a flowchart of an example method for controlling drainage of a dehumidifier
according to an embodiment of the disclosure. As shown in Fig. 2, after Step S110,
the method for controlling the drainage further includes the following steps.
[0035] Step S212: It is detected whether a compressor starts operating. When it is detected
that the compressor starts operating, Step S214 is executed. Otherwise, Step S216
is executed.
[0036] Step S214: A power device is controlled to operate in a preset working mode.
[0037] Step S216: A dehumidifier is controlled to enter a state of being powered off.
[0038] Alternatively, after the power device is controlled to operate for a second preset
period, it is detected whether the compressor starts operating. When the compressor
starts operating, the power device is controlled to operate in a preset working mode,
wherein the preset working mode may be one of the following modes.
[0039] Mode 1: The power device is controlled to operate once at a preset time interval
when the compressor operates, each operation lasting for a set operation period. For
example, the power device starts operating at an interval (10min), operates for 5min,
waits for 10min, and then continues operating for 5min.
[0040] Mode 2: After stopping for a period of time, the power device starts operating, and
keeps operating until the compressor stops operating.
[0041] When it is detected that the compressor does not start operating, the dehumidifier
is controlled to be powered off. Water in the water collecting device has been drained
off from operation starting to operation stopping of the power device, at this time,
the compressor still does not start operating, it is shown that the dehumidifier still
does not execute a dehumidification operation, so the dehumidifier may be controlled
to be powered off, thereby avoiding the problem of energy waste due to the fact that
the dehumidifier continuously operates but does not execute the dehumidification operation.
[0042] In the embodiments of the disclosure, the step that it is detected whether the compressor
starts operating may be executed in an operation process of the power device. In an
example embodiment, when it is detected that the compressor does not start operating,
after the power device operates for the second preset period, the dehumidifier is
controlled to be powered off. When it is detected that the compressor starts operating,
after the power device operates for the second preset period, the power device may
be controlled to operate in a preset working mode.
[0043] Fig. 3 is a flowchart of another example method for controlling drainage of a dehumidifier
according to an embodiment of the disclosure. Step S102 to Step S212 and Step S216
in the drainage control method are identical to Step S102 to Step S212 and Step S216
as shown in Fig. 2 in sequence, which will not be elaborated. As shown in Fig. 3,
the step that the power device is controlled to operate in a preset working mode includes
the following steps.
[0044] Step S2141: a stopping period at which the power device stops operating is detected,
wherein the stopping period is a period within which the power device stops operating.
[0045] Step S2142: It is judged whether the stopping period reaches a third preset period.
When it is determined that the stopping period reaches the third preset period, Step
S2143 is executed. Otherwise, it is continuously judged whether the stopping period
reaches the third preset period.
[0046] Step S2143: The power device is controlled to start draining water off.
[0047] Step S2144: After the operation period of the power device reaches a fourth preset
period, the power device is controlled to stop operating. After the power device stops
operating, the power device is re-started after the third preset period, and after
the operation period of the power device reaches the fourth preset period, the power
device is controlled to stop operating, wherein the third preset period and the fourth
preset period may be set according to the model of the dehumidifier.
[0048] Step S2145: The number of operating times of the power device under a preset working
mode is recorded. The number of the operating times under the preset working mode
is the number of times of operation starting of the power device under the preset
working mode, the number of the operating times does not include the number of previous
operation starting of the power device under the preset working mode.
[0049] Step S2146: It is judged whether the number of the operating times reaches a preset
value. When it is determined that the number of the operating times does not reach
a preset value, Step S2141 is re-executed.
[0050] The number of the operating times of the power device under the preset working mode
is compared with the preset value, it is judged whether the number of the operating
times reaches the preset value, when the number of the operating times does not reach
the preset value, the stopping period after the power device stops operating previously
is continuously detected, and when the stopping period reaches the third preset period,
the power device is controlled to start operating and the number of the operating
times is recorded. The operation is repeatedly executed until the number of the operating
times of the power device reaches the preset value.
[0051] According to the embodiments of the disclosure, after it is detected that the compressor
starts operating, the power device is controlled to work in the above-mentioned preset
working mode. That is, the power device is controlled to operate once at an interval
namely the third preset period, each operation lasting for the fourth preset period
until the power device operates for the preset value. Thus, it can be ensured that
after the compressor starts operating, the power device is controlled to operate according
to time, thereby draining water off from the water collecting device, and achieving
the aim of timely drainage.
[0052] Alternatively, as shown in Fig. 3, when it is determined that the number of the operating
times reaches the preset value, Step S102 is returned to be executed, and the number
of the operating times under the preset working mode is zeroed. The number of the
operating times under the preset working mode is zeroed, in order that when the power
device re-enters the preset working mode, the count of repeated operation starting
is re-recorded.
[0053] Alternatively, the fourth preset period and the second preset period in the above-mentioned
embodiment have a same duration. That is, lasting time for operation of the power
device at each time is identical. Thus, a control policy of the power device can be
simplified. The preset value of operation of the power device may be determined in
the following modes: detecting humidity of an environment where the dehumidifier is
located; and determining the preset value according to the humidity.
[0054] Alternatively, the preset value which is set may be stored on a memory of the dehumidifier
according to a corresponding relation between the humidity of the environment and
the preset value. For example, when the humidity is 90%, the corresponding preset
value is 5. Thus, after the humidity of the environment where the dehumidifier is
located is detected, the corresponding preset value may be found from the memory according
to the humidity, thereby determining the number of operating times of the power device
to be achieved under the preset working mode.
[0055] Fig. 4 is a flowchart of a further example method for controlling drainage of a dehumidifier
according to an embodiment of the disclosure. As shown in Fig. 4, the drainage control
method includes the following steps.
[0056] Step S401: Under a water pump mode, it is detected whether a compressor stops. The
water pump mode may be called as a power mode. That is, a power device is in an energized
operable state. When so, it is shown that the compressor stops operating, and Step
S402 is executed. Otherwise, it is shown that the compressor operates, and Step S401
may be continuously executed.
[0057] Step S402: Stopping period at which the power device stops operating is detected.
When the compressor stops for Xmin namely a first preset period in the embodiments
of the disclosure, Step S403 is executed.
[0058] Step S403: The power device operates for T
pump, that is, the power device operates for a second preset period.
[0059] Step S404: It is detected whether the compressor operates. if so, Step S405 is executed.
Otherwise, the dehumidifier is controlled to be powered off.
[0060] Step S405: The power device stops operating for T
stop, that is, the power device stops operating for a third preset period.
[0061] Step S406: It is judged whether n is equal to K, where n may refer to the number
of operating times of the power device when the compressor operates, and K is a preset
value in the above-mentioned embodiments of the disclosure. When n is equal to K,
Step S407 is executed. Otherwise, n is added with 1, and Step S403 is re-executed.
[0062] Step S407: It is detected whether the compressor stops. if so, n is zeroed, and Step
S402 is re-executed. Otherwise, it is continuously detected whether the compressor
stops.
[0063] Alternatively, when a power mode of the machine is started, during normal working
namely starting of the compressor, a controller detects the starting/stopping situation
of the compressor. When it is detected that the compressor stops operating, a timer
measures time for Xmin, and then the power device starts draining water off, the power
device operates for T
pump, and then stops operating. At this time, the controller detects whether the compressor
is started. When the compressor is not started, the entire machine enters a power-off
state. When the compressor is started, the power device stops for T
stop, and then the power device is re-started to continue operating for T
pump and stops. The operation is repeated for K times, K being determined by the humidity
of the dehumidifier (e.g., when the humidity is 90%, K=5). After the operation is
repeated for K times, the controller will continuously detect the starting/stopping
situation of the compressor. When the compressor re-stops operating, the operation
is repeated again.
[0064] The embodiments of the disclosure also provide a drainage control device of a dehumidifier.
The functions of the device may be achieved by means of the dehumidifier. It is important
to note that the drainage control device of the dehumidifier according to the embodiment
of the disclosure may be configured to execute the drainage control method of the
dehumidifier provided by the embodiments of the disclosure, and the drainage control
method of the dehumidifier provided by the embodiments of the disclosure may also
be executed by means of the drainage control device of the dehumidifier provided by
the embodiments of the disclosure.
[0065] Fig. 5 is a schematic diagram of a device for controlling drainage of a dehumidifier
according to an embodiment of the disclosure. As shown in Fig. 5, the drainage control
device of the dehumidifier includes: a first detecting element 10, a first controlling
element 20, a second detecting element 30, a first judging element 40, and a second
controlling element 50.
[0066] The first detecting element 10 is configured to detect, when a compressor of a dehumidifier
is powered on, whether the compressor operates or not.
[0067] The compressor of the dehumidifier is powered on, i.e., the compressor is started.
Under this state, the compressor may be standby, i.e., the compressor is energized
but does not work, or the compressor may be in an operation state namely a dehumidification
working state. When the compressor is de-energized, it may be shown that the dehumidifier
does not execute a dehumidification operation. In this case, water may not be drained
off. When the compressor is energized, it is detected whether the compressor operates
or not. When the compressor operates, the dehumidifier is collecting, via a water
collecting device, water obtained by treating air by the compressor. When the compressor
stops operating, since the compressor is energized, it is shown that the compressor
may stop operating after dehumidification reaches a certain extent, and may be standby.
[0068] The first controlling element 20 is configured to control, when it is detected that
the compressor stops operating, a power device of the dehumidifier to start draining
water off after a first preset period.
[0069] When it is detected that the compressor stops operating, the power device is controlled
to start draining water off after the first preset period. Alternatively, when it
is detected that the compressor stops operating, i.e., the compressor is standby,
a controller controls a timer to start timing. When time measured by the timer reaches
the first preset period, the timer returns a timing reaching signal to the controller,
and after receiving the signal, the controller controls the power device to start
draining water off. Certainly, the control may also inquire the measured time of the
timer, and when it is inquired that the measured time reaches the first preset period,
the power device is controlled to start draining water off. Wherein, the first preset
period may be determined according to the model of the dehumidifier and environment
parameters.
[0070] The second detection 30 is configured to detect operation period of the power device.
[0071] After the power device starts draining water off, the controller detects the operation
period of the power device namely drainage time. The operation period may be started
by means of the timer after the power device starts operating.
[0072] The first judging element 40 is configured to judge whether the operation period
reaches a second preset period or not.
[0073] The second controlling element 50 is configured to control, when it is determined
that the operation period reaches the second preset period, the power device to stop
operating.
[0074] After the power device is started, it is unnecessary to be draining water off all
the time. Therefore, after the operation period of the power device is detected, it
is judged whether the operation period reaches the second preset period. When so,
the power device may be controlled to stop operating, thereby preventing the power
device from operating all the time to waste electric energy. If not, the power device
continuously operates. Wherein, the second preset period may be determined according
to the model of the dehumidifier, and may also be determined according to parameters
such as a drainage amount of the dehumidifier within unit time and a usual water collecting
amount in the water collecting device. When the operation period of the power device
reaches the second preset period, it is shown that water in the water collecting device
has been drained off or water drainage reaches a certain amount.
[0075] According to the embodiments of the disclosure, when the compressor of the dehumidifier
is powered on, it is detected whether the compressor operates or not. When it is detected
that the compressor stops operating, the power device of the dehumidifier is controlled
to start draining water off after the first preset period. When drainage time of the
power device reaches the second preset period, the power device is controlled to stop
operating, i.e., to stop draining water off. In such a way, by controlling the starting
time and stopping period of the power device by means of time, the problem that water
cannot be drained from the dehumidifier due to abnormal water level detection is solved,
thereby achieving the effect of controlling the dehumidifier to drain water off by
means of time instead of water level detection.
[0076] Alternatively, the drainage control device further includes: a third detecting element,
configured to detect, in the process of controlling the power device to operate, whether
the compressor starts operating or not; a third controlling element, configured to
control, when it is detected that the compressor starts operating, the power device
to operate in a preset working mode; and a fourth controlling element, configured
to control, when it is detected that the compressor does not start operating, the
dehumidifier to be powered off.
[0077] Alternatively, after the power device is controlled to stop operating, it is detected
whether the compressor starts operating. When the compressor starts operating, the
power device is controlled to operate in a preset working mode, wherein the preset
working mode may be one of the following modes.
[0078] Mode 1: The power device is controlled to operate once at a preset time interval
when the compressor operates, each operation lasting for a set operation period. For
example, the power device starts operating at an interval (10min), operates for 5min,
waits for 10min, and then continues operating for 5min.
[0079] Mode 2: After stopping for a period of time, the power device starts operating, and
keeps operating until the compressor stops operating.
[0080] When it is detected that the compressor does not start operating, the dehumidifier
is controlled to be powered off. Water in the water collecting device has been drained
off from operation starting to operation stopping of the power device, at this time,
the compressor still does not start operating, it is shown that the dehumidifier still
does not execute a dehumidification operation, so the dehumidifier may be controlled
to be powered off, thereby avoiding the problem of energy waste due to the fact that
the dehumidifier continuously operates but does not execute the dehumidification operation.
[0081] In the embodiments of the disclosure, the step that it is detected whether the compressor
starts operating may be executed in an operation process of the power device. Wherein,
when it is detected that the compressor does not start operating, after the power
device operates for the second preset period, the dehumidifier is controlled to be
powered off. When it is detected that the compressor starts operating, after the power
device operates for the second preset period, the power device may be controlled to
operate in a preset working mode.
[0082] Alternatively, the third controlling element includes: a detecting component, configured
to detect stopping period at which the power device stops operating, the stopping
period being a period of time within which the power device stops operating; a first
judging component, configured to judge whether the stopping period reaches a third
preset period or not; a first controlling component, configured to control, when it
is determined that the stopping period reaches the third preset period, the power
device to start draining water off; a second controlling component, configured to
control, after the operation period of the power device reaches a fourth preset period,
the power device to stop operating; a recording component, configured to record the
number of operating times of the power device under a preset working mode; and a second
judging component, configured to judge whether the number of the operating times reaches
a preset value or not, wherein the detecting component is further configured to detect,
when it is determined that the number of the operating times does not reach the preset
value, the stopping period at which the power device stops operating.
[0083] After the power device stops operating, the power device is re-started after the
third preset period, and after the operation period of the power device reaches the
fourth preset period, the power device is controlled to stop operating, wherein the
third preset period and the fourth preset period may be set according to the model
of the dehumidifier.
[0084] The number of the operating times under the preset working mode is a count of operation
starting of the power device under the preset working mode, the count excluding a
count of previous operation starting of the power device under the preset working
mode.
[0085] The number of the operating times of the power device under the preset working mode
is compared with the preset value, it is judged whether the number of the operating
times reaches the preset value, when the number of the operating times does not reach
the preset value, stopping period after the power device stops operating previously
is continuously detected, and when the stopping period reaches the third preset period,
the power device is controlled to start operating and the number of the operating
times is recorded. The operation is repeatedly executed until the number of the operating
times of the power device reaches the preset value.
[0086] According to the embodiments of the disclosure, after it is detected that the compressor
starts operating, the power device is controlled to work in the above-mentioned preset
working mode. That is, the power device is controlled to operate once at an interval
namely the third preset period, each operation lasting for the fourth preset period
until the power device operates for the preset value. Thus, it can be ensured that
after the compressor starts operating, the power device is controlled to operate according
to time, thereby draining water off from the water collecting device, and achieving
the aim of timely drainage.
[0087] Alternatively, the first detecting element is further configured to detect, when
it is determined that the number of the operating times reaches the preset value,
whether the compressor operates or not, and zero the number of the operating times
under the preset working mode. The number of the operating times under the preset
working mode is zeroed, in order that when the power device re-enters the preset working
mode, the count of repeated operation starting is re-recorded.
[0088] Alternatively, the fourth preset period and the second preset period have a same
duration. That is, lasting time for operation of the power device at each time is
identical. Thus, a control policy of the power device can be simplified.
[0089] The drainage control device further includes: a third detecting element, configured
to detect humidity of an environment where the dehumidifier is located; and a determining
element, configured to determine the preset value according to the humidity.
[0090] Alternatively, the preset value which is set may be stored on a memory of the dehumidifier
according to a corresponding relation between the humidity of the environment and
the preset value. For example, when the humidity is 90%, the corresponding preset
value is 5. Thus, after the humidity of the environment where the dehumidifier is
located is detected, the corresponding preset value may be found from the memory according
to the humidity, thereby determining the number of operating times of the power device
to be achieved under the preset working mode.
[0091] The embodiments of the disclosure also provide a dehumidifier. The dehumidifier may
be configured to execute the drainage control method according to the embodiment of
the disclosure, and may also be configured to implement the drainage control device
according to the embodiment of the disclosure. Specifically, the drainage control
method according to the embodiment of the disclosure may be executed by means of a
controller of the dehumidifier.
[0092] The dehumidifier includes: a compressor; a power device; a timer, configured to measure
a first preset period and a second preset period; and a controller, connected to the
compressor, the power device and the timer separately, and configured to detect, when
the compressor of the dehumidifier is powered on, whether the compressor operates
or not, control, when it is detected that the compressor stops operating, the power
device to start draining water off after the first preset period, and control the
power device to stop operating after the second preset period.
[0093] It is important to note that the process of controlling drainage by the controller
of the dehumidifier according to the embodiment of the disclosure may refer to the
drainage control method according to the embodiment of the disclosure, which will
not be elaborated herein.
[0094] As shown in Fig. 6, the dehumidifier further includes: a water collecting device
605, a joint device 604, a water tube 602, and a water outlet 603. The water collecting
device 605 is connected to a water way via the joint device 604, water is guided to
a power device 601 by using the water tube 602, and the water flows to the water outlet
603 by means of the power device 601 and is drained off finally.
[0095] In an example embodiment, the condensed water produced during normal working of the
dehumidifier will be collected in the water collecting device 605. When water is drained
off by using the power device 601, the power device 601 is controlled to start or
stop under the control of a time program of the controller (not shown in the figure).
When the power device 601 is started, the water in the water collecting device 605
flows to the power device 601 via the joint device 604 and the water tube, and the
power device 601 drains the water off to the water outlet 603 via the water tube 602
for drainage.
