[0001] The present invention relates to a dishwasher comprising a heat pump.
[0002] In dishwashers, heat pumps are used for decreasing the energy consumption and improve
the drying performance. In heat pump dishwashers, the heat pump is composed of the
compressor, the condenser, the throttle valve and the evaporator. The components of
the heat pump are connected via a pipe line and the heat pump operates by means of
the cycle fluid in the line. The condenser is a tube bundle having a hot surface and
enables the water to be heated by being positioned in the washing liquid of the dishwasher.
The evaporator has a cold surface and is positioned so as to contact the ambient air.
The evaporator absorbs heat from the environment and provides the heat transfer to
the compressor and the condenser. In this type of heat pump systems, for heating the
water, the compressor is operated to enable the condenser to heat the water, and the
evaporator is enabled to absorb heat from the environment to support the condenser
which heats the water. In order to ensure the continuity of the operation of the heat
pump, the evaporator continuously absorbs heat from the environment, and, while using
the heat for the heat pump, causes the discharged air to cool down. The cooled-down
air is discharged after passing through the evaporator. The section through which
the cold air is discharged is positioned at the rear side of the dishwasher. The cold
air remaining between the mounting gap and the dishwasher increases in time so as
to cover the entire rear side. This causes heat exchange between the washing tub and
the cold air, adversely affecting the washing and drying performance. Moreover, the
accumulation of cold air between the mounting gap and the dishwasher leads to deformation
in the kitchen furniture.
[0003] In the state of the art German Patent Document No.
DE3600820, a dishwasher is disclosed, comprising protective members which are mounted to the
sides of the body and which protect the kitchen furniture from steam.
[0004] In the state of the art German Patent Document No.
DE102019100004, a dishwasher is disclosed, comprising sealing element which is arranged or can be
arranged between the rear wall of the dishwasher and an adjacent room wall above the
air outlet.
[0005] The aim of the present invention is the realization of a dishwasher with improved
washing and drying performance.
[0006] The dishwasher realized in order to attain the aim of the present invention, explicated
in the first claim and the respective claims thereof, comprises a body; a washing
tub which is disposed in the body and wherein the kitchen items to be washed are placed;
and a heat pump which is disposed between the washing tub and the body. The heat pump
comprises a first heat exchanger which absorbs heat from the environment so as to
enable the water used in the washing step to be heated; a second heat exchanger which
transfers the heat received from the first heat exchanger to the washing tub; and
a compressor which performs the refrigerant cycle between the first heat exchanger
and the second heat exchanger.
[0007] The dishwasher of the present invention comprises a closure member which prevents
the air, the heat of which is absorbed by the heat pump, from being delivered behind
the body. By means of the closure member, the cooled-down air is not delivered behind
the body. Thus, the heat exchange with the interior of the washing tub is prevented,
and the heat in the washing tub is insulated.
[0008] According to the present invention, the dishwasher comprises the closure member which
is disposed on the lower edge of the body between the body and mounting gap where
the body is disposed. By positioning the closure member at the lower edge of the body,
the rising of the cold air and the heat exchange with the washing tub are prevented.
[0009] According to the present invention, the dishwasher comprises the closure member which
is a shutter opening in one direction. One edge of the closure member in the form
of a shutter can open in one direction by making a constant circular movement on the
body. Thus, the area behind the dishwasher can be reached when desired. However, the
cold air is prevented from reaching behind the dishwasher.
[0010] In an embodiment of the present invention, the dishwasher comprises the closure member
having dimensions which can be adjusted depending on the distance between the body
and the mounting gap. Thus, during any mounting, the dimensions of the closure member
can be changed depending on the dimensions of the mounting gap and the dishwasher.
Consequently, the space between the mounting gap and the body is completed closed.
[0011] In an embodiment of the present invention, the dishwasher comprises the closure member
in the form of an accordion. Thanks to being in the form of an accordion with foldable
surfaces, the closure member can be adjusted depending on the distance between the
mounting gap and the body. Moreover, since the surface area increases, the cold air
is enabled to hit a larger surface area, thus dampening any noise.
[0012] In an embodiment of the present invention, the dishwasher comprises the closure member
which is manufactured from a layered insulation material. The insulation material
can be easily separated from the areas predetermined by the manufacturer, and thus
the dimensions thereof can be adjusted.
[0013] In an embodiment of the present invention, the dishwasher comprises a spring which
is disposed between the mounting gap and the body, and the closure member which moves
depending on the spring. The spring shortens and lengthens depending on the distance
between the mounting gap and the body, thus the dimensions of the closure member can
be changed.
[0014] In an embodiment of the present invention, the dishwasher comprises a screw which
is disposed between the mounting gap and the body, and the closure member which moves
depending on the screw. The screw moves depending on the distance between the mounting
gap and the body, thus the dimensions of the closure member can be changed.
[0015] By means of the present invention, a dishwasher is realized, comprises a closure
member which completely closes the distance between the mounting gap and the body.

[0018] The dishwasher (1) comprises a body (2); a washing tub (3) that is disposed in the
body (2) and wherein the washing process is performed; and a heat pump (7) which is
arranged under the washing tub (3) and which has a first heat exchanger (4) enabling
the water to be used in the washing step to be heated by drawing heat from the environment,
a second heat exchanger (5) transferring the heat received from the first heat exchanger
(4) to the washing water and a compressor (6) fluidly connected to the first heat
exchanger (4) and the second heat exchanger (5) so as to realize the refrigerant cycle.
By means of the heat pump (7), the air in the washing tub (3) is dehumidified and
sent back into the washing tub (3). Thus, the water droplets remaining on the kitchen
items in the washing tub (3) after the washing process can be removed more quickly,
thereby improving the drying performance
[0019] The dishwasher (1) of the present invention comprises a closure member (8) which
prevents the air cooling down as the heat pump (7) draws the heat of the ambient air
from being delivered behind the body (2). The first heat exchanger (4) draws heat
from the environment and transfers the same to the second heat exchanger (5) to heat
the water. Therefore, the temperature of the air leaving the first heat exchanger
(4) decreases. By means of the closure member (8), the delivery of the cooled-down
air behind the body and the heat exchange with the washing tub (3) are prevented.
Thus, the heat in the washing tub (3) is insulated.
[0020] In an embodiment of the present invention, the dishwasher (1) comprises the closure
member (8) which is disposed on the lower edge of the body (2) between the body (2)
and the mounting gap where the body (2) is disposed. The dishwasher (1) is mounted
to the mounting gap present in the environment. The closure member (8) closes the
distance between the mounting gap and the body (2). The closure member (8) is mounted
to the lower edge of the body (2). Thus, the cold air is prevented from accumulating
and rising towards behind the body (2).
[0021] In an embodiment of the present invention, the dishwasher (1) comprises the closure
member (8) which is a shutter (9) mounted on the body (2) so as to open in one direction.
The closure member (8) can be a shutter (9) which is fixed on the body (2) at one
side and which can rotate about the fixed side. The shutter (9) opens in one direction.
Thus, the cold air is prevented from being delivered behind the body (2) while the
service staff can easily reach the area behind the body (2) in case of a malfunction.
In an embodiment of the present invention, the dishwasher (1) comprises the closure
member (8) which can be adjusted depending on the distance between the body (2) and
the mounting gap. The distance between the mounting gap and the body (2) changes depending
on the dimensions of the mounting gap and the dimensions of the body (2). Therefore,
by means of the closure member (8) having adjustable dimensions, the distance between
the mounting gap and the body (2) can be completely closed.
[0022] In an embodiment of the present invention, the dishwasher (1) comprises the closure
member (8) in the form of a foldable accordion. Thanks to being in the form of an
accordion having foldable surfaces, the closure member (8) can be adapted to various
dimensions. Moreover, since the surface area is increased, noises which may be caused
by air flow are dampened.
[0023] In an embodiment of the present invention, the dishwasher (1) comprises the closure
member which is manufactured from a layered insulation material. By means of the layered
structure, the dimensions of the closure member (8) can be changed depending on the
distance between the mounting gap and the body (2). By means of the insulation material,
heat insulation is provided while dampening the noises caused by air flow.
[0024] In an embodiment of the present invention, the dishwasher (1) comprises a spring
(10) which is disposed between the mounting gap and the body (2), and the closure
member (8) which moves depending on the spring (10). The spring (10) shortens and
lengthens depending on the distance between the mounting gap and the body (2), thus
the dimensions of the closure member (8) can be changed.
[0025] In an embodiment of the present invention, the dishwasher (1) comprises a screw (11)
which is disposed between the mounting gap and the body (2), and the closure member
(8) which moves depending on the screw (11). The screw (11) moves depending on the
distance between the mounting gap and the body (2), thus the dimensions of the closure
member (8) can be changed.
[0026] By means of the present invention, a dishwasher (1) is realized, wherein the air
cooled down by the heat pump (7) is prevented from being delivered behind the body
(2) by means of the closure member (8) disposed between the mounting gap and the body
(2) and wherein heat insulation is provided. The closure member (8) can be adjusted
depending on the distance between the body (2) and the mounting gap such that no space
remains therebetween. Thus, the heat exchange between the cold air and the washing
tub (3) is prevented, increasing the washing and drying performance.
