The first air duct 110 has a first air inlet 111 and a first air outlet 112, and the first air inlet 111 and the first air outlet 112 are adapted to be respectively communicated with the inner container of the dishwasher; the second air duct 120 has a second air inlet 121 and a second air outlet 122, and the second air inlet 121 and the second air outlet 122 are respectively communicated with the outside. The heat exchanger 200 is disposed on the body 100, and the heat exchanger 200 is respectively communicated with the first air duct 110 and the second air duct 120. The first fan 310 is disposed in the first air duct 110, and the second fan 320 is disposed in the second air duct 120.
Therefore, the first fan 310 controls the water vapor in the inner container to enter the first air duct 110 through the first air inlet 111, and flow into the inner container from the first air outlet 112 after heat exchange with the heat exchanger 200; meanwhile, the second fan 320 draws air from the external environment through the second air inlet 121, so that the air exchanges heat with the heat exchanger 200 and is finally discharged to the external environment. In this way, the gas containing water vapor is condensed while flowing through the heat exchanger 200, and the released heat is absorbed by the outside air flowing through the heat exchanger 200, that is, the water vapor is condensed by the outside air, so that the drying system can be configured using a limited space.
According to the drying device 10 for the dish washer, disclosed by the embodiment of the invention, the purpose of continuously reducing the humidity of the gas in the inner container is achieved, the drying effect is improved, the condensation of the gas containing the water vapor on a cabinet or the ground is avoided in the drying process, and the user experience is improved.
In short, the drying device 10 for a dishwasher according to the embodiment of the present invention can solve the technical problems existing in the related art, and has the advantages of good drying effect, high drying efficiency, small occupied space, and good user experience.
According to some embodiments of the present invention, as shown in fig. 1, a portion of the heat exchanger 200 is located in the first air duct 110, and another portion of the heat exchanger 200 is located at the second air inlet 121. In this way, the water vapor in the first air duct 110 may exchange heat with the portion of the heat exchanger 200, and the external air may exchange heat with the other portion of the heat exchanger 200, so that the external air may exchange energy with the water vapor in the first air duct 110, and the occupied space is reduced.
Further, as shown in fig. 1, the first air duct 110 includes a first transition section 113, a heat exchange section 114, a second transition section 115, and a device mounting section 116 in a direction from the first air inlet 111 to the first air outlet 112, the portion of the heat exchanger 200 is located at the heat exchange section 114, and the first fan 310 is located at the device mounting section 116. That is, the portion of the heat exchanger 200 is located upstream of the first fan 310 in the air flow direction, so that heat exchange is more sufficient and drying effect is better.
Advantageously, as shown in fig. 1, the first transition section 113 is used to communicate the first air inlet 111 and the heat exchange section 114, where the highest position of the first transition section 113 is higher than the highest position of the first air inlet 111, for example, the first transition section 113 is generally U-shaped, an end of the first transition section 113 adjacent to the first air inlet 111 is located above the first air inlet 111, the air flow from the first air inlet 111 to the first transition section 113 gradually flows upwards, and the air flow from the first transition section 113 to the heat exchange section 114 gradually flows downwards. In this way, water during washing may be prevented from directly entering the heat exchanger 200 from the first air inlet 111.
Advantageously, as shown in fig. 1, the heat exchange section 114 is a straight section, and a drain opening 117 is provided at the bottom of the heat exchange section 114 for draining condensed water accumulated at the bottom of the heat exchange section 114. For example, a water storage tank may be provided at the bottom of the heat exchange section 114 for storing condensed water, a drain port 117 is provided in the water storage tank, the drain port 117 is connected to a hose, and the condensed water is smoothly led out to a water cup or a drain pipe by the hose.
Optionally, as shown in fig. 1, the second transition section 115 extends from the heat exchange section 114 obliquely upward relative to the vertical to prevent condensate from entering the first fan 310.
In some embodiments of the present invention, as shown in fig. 1, the portion of the heat exchanger 200 includes a plurality of first fins 210, the plurality of first fins 210 being arranged in a width direction of the first air path 110, each first fin 210 extending in a length direction of the first air path 110.

For example, the plurality of first fins 210 are connected to each other to form a corrugated shape, and the plurality of second fins 220 are connected to each other to form a corrugated shape.
Wherein the plurality of second fins 220 may be arranged in two layers on the plurality of first fins 210. That is, the heat exchanger 200 includes a plurality of first fins 210 positioned at the middle layer and a plurality of second fins 220 positioned at opposite sides of the middle layer, respectively, such that the gas containing water vapor condenses while flowing through the plurality of first fins 210 positioned at the middle layer, the released heat is transferred to the two second fins 220 positioned at the outer side, the outside air absorbs heat while flowing through the second fins 220, thereby achieving heat and cold exchange, and then the outside air is discharged again and the gas having reduced humidity is introduced into the inner container again.
Advantageously, as shown in fig. 3, the heat exchanger 200 further includes a heat exchange plate 230, wherein the heat exchange plate 230 has a heat exchange cavity therein, a plurality of first fins 210 are disposed in the heat exchange cavity, and a plurality of second fins 220 are distributed on opposite side surfaces of the heat exchange plate 230. That is, the first fin 210 located in the middle layer is separated from the two second fins 220 by the heat exchange plates 230, respectively, to improve the heat exchange effect. For example, the heat exchange plate 230 is a metal member, and surfaces of the heat exchange plate 230 facing the first fin 210 and the second fin 220 are both planar.
It will be appreciated that the number of layers of the first fins 210 and the second fins 220 is not particularly limited, and the number of layers of the first fins 210 into which water vapor is introduced and the number of layers of the second fins 220 into which outside air is introduced are also not particularly limited, as long as the extending directions of the first fins 210 and the second fins 220 are satisfied so as not to obstruct the flow of air.
According to some embodiments of the present invention, the drying device 10 for a dishwasher further comprises: the heater 400 is arranged on the device mounting section 116, and the heater 400 is arranged between the first fan 310 and the first air outlet 112 so as to heat the air flow to be introduced into the liner, thereby playing a role in hot air drying and enhancing the drying effect. For example, the heater 400 may be a PTC heater, and the heater 400 may be turned on when quick and efficient drying is required, and the heater 400 may be turned off when an economical drying mode is required.

The temperature controller 430 is connected to at least one of the heating plate 410 and the third fin 420, i.e., the temperature controller 430 may be connected to the heating plate 410 or the third fin 420, and the temperature controller 430 may be connected to the heating plate 410 and the third fin 420, respectively. The wire harness 440 is connected to the heating plate 410 to achieve heating of the heating plate 410.
When the heater 400 is turned on, the temperature of the heating plate 410 is increased and heat is transferred to the third fin 420, and the dehumidified gas flows through the third fin 420 and takes away the heat, and then enters the inner container from the first air outlet 112, so that hot air drying is realized. The first fin 210, the second fin 220 and the third fin 420 may be metal pieces, so as to ensure a good heat exchange effect.
