For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] The present invention will be further described in detail below through specific embodiments in conjunction with the drawings.

[0040] See Figure 1 and Figure 2 This embodiment provides a drying device, which includes a first channel 100, a second channel 200, a third channel 300, a confluence channel 400, and a blower 500. Among them, the air inlet of the blower 500 communicates with the outside, the air inlet ends of the first channel 100 and the second channel 200 are both communicated with the air outlet of the blower 500, the air outlet end of the first channel 100 and the air inlet end of the third channel 300 are arranged at intervals and are both communicated with the inner cavity of the dishwasher, the air outlet ends of the second channel 200 and the third channel 300 are both communicated with the confluence channel 400, and the confluence channel 400 communicates with the outside.

[0041] After the dishwasher finishes washing, the blower 500 is started. The blower 500 can suck the dry air from the outside and discharge it into the first channel 100 and the second channel 200. Among them, the dry air in the first channel 100 can enter the inner cavity of the dishwasher along the first channel 100, so that the air pressure in the inner cavity increases; the dry air in the second channel 200 can be discharged to the outside through the confluence channel 400, so that a certain negative pressure environment is formed in the confluence channel 400. In this way, the humid air in the inner cavity will flow along the third channel 300 to the confluence channel 400 under the action of the air pressure difference, and mix with the dry air outside in the confluence channel 400 and finally be discharged. Thus, the humid air in the inner cavity will gradually be replaced by the dry air from the outside, the humidity of the inner cavity of the dishwasher can be reduced, it is not easy to breed bacteria and generate peculiar smells, and furthermore, the tableware in the inner cavity of the dishwasher is not easy to be contaminated.

[0042] It should be noted that the blower 500 in the drying device provided in this embodiment can not only provide the power to extract the humid air in the inner tank, but also provide the power to inject dry air into the inner tank, achieving the effect of dual use of one machine. In this way, not only can the cost be saved, but also the energy consumption can be reduced.

[0043] Preferably, a heat-conducting baffle 600 is arranged in the third channel 300, and the heat-conducting baffle 600 is connected to the side wall of the third channel 300 in contact with the outside, so that the heat-conducting baffle 600 can dissipate its own temperature into the cold air outside through the side wall of the third channel 300 in contact with the outside. In this way, the heat-conducting baffle 600 can be maintained at a lower temperature; the heat-conducting baffle 600 is arranged at an angle with the flow direction of the third channel 300. Thus, the humid air passing through the third channel 300 will hit the heat-conducting baffle 600, and at least part of the water vapor in the humid air will condense into condensed water on the heat-conducting baffle 600 with a lower temperature. In this way, the temperature and humidity of the air discharged to the outside can be reduced, and the impact on the external environment can be reduced; in addition, if there is a cabinet beside the dishwasher, reducing the temperature and humidity of the discharged air can reduce the damage to the cabinet.

[0044] Preferably, the heat-conducting baffle 600 is placed perpendicular to the flow direction of the third channel 300, that is to say, the surface with the largest area on the heat-conducting baffle 600 is perpendicular to the flow direction of the third channel 300, so as to improve the condensation effect of the water vapor in the third channel 300.

[0045] Furthermore, one end of the heat-conducting baffle 600 is connected to the side wall of the third channel 300 close to the dishwasher body, and the other end of the heat-conducting baffle 600 is connected to the side wall of the third channel 300 away from the dishwasher body. Thus, not only is it convenient to increase the area of the heat-conducting baffle 600 and improve the condensation efficiency, but also the connection strength between the heat-conducting baffle 600 and the third channel 300 can be improved.

[0046] Preferably, a plurality of heat-conducting baffles 600 can be arranged, and the plurality of heat-conducting baffles 600 are arranged at intervals along the ventilation direction of the third channel 300, so as to increase the total contact area between the heat-conducting baffles 600 and the humid air, improve the condensation efficiency of the water vapor in the humid air, further reduce the temperature and humidity of the air discharged to the external environment, and reduce the impact on the external environment.

[0047] Particularly, a metal sheet, a plastic sheet or a semiconductor refrigerator can be used as the above-mentioned heat-conducting baffle 600.

[0048] In the specific structure of the drying device, a partition plate 700 and two side plates 800 are provided. Among them, the two side plates 800 are arranged at intervals relatively. The partition plate 700 is connected between the two side plates 800. Thus, the space between the two side plates 800 can be divided into several parts by the partition plate 700, forming a first channel 100, a second channel 200, a third channel 300 and a confluence channel 400.

[0049] Furthermore, in the specific structure of the drying device, a surrounding plate can also be provided to connect the edges of the two side plates 800, forming a box similar to a cuboid, which is more beautiful.

[0050] Specifically, an air inlet 810 and an air outlet 820 are opened on the side plate 800. Among them, the air inlet 810 is at the air inlet end of the third channel 300, and the air outlet 820 is at the air outlet end of the first channel 100. Both the air inlet 810 and the air outlet 820 are communicated with the inner tank of the dishwasher to realize the communication between the first channel 100 and the third channel 300 and the inner tank.

[0051] Preferably, a condensate drain hole 830 is opened on the side plate 800, and the partition plate 700 is used to guide the condensate generated in the third channel 300 and the confluence channel 400 to the condensate drain hole 830, so as to smoothly drain the condensate through the condensate drain hole 830 and prevent the condensate from accumulating in the drying device.

[0052] Furthermore, the above-mentioned condensate drain hole 830 can be set to be communicated with the inner tank of the dishwasher. Thus, the condensate generated in the third channel 300 and the confluence channel 400 of the drying device can flow back to the inner tank through the condensate drain hole 830. When the drying is about to be completed or after the drying is completed, the drainage function of the dishwasher can be used to drain the residual water (including condensate) in the inner tank from the inner tank, without the need to additionally set a condensate recovery structure, which is convenient for cost saving and thus saves the manpower and time required for manually cleaning the condensate recovery structure.

[0053] It should be noted that the condensate in the third channel 300 can also flow back to the inner tank through the air inlet on the side plate 800.

[0054] Specifically, the two ends of the above-mentioned heat conduction baffle 600 can be fixedly connected to the two side plates 800 respectively.

[0055] In addition, a heating device 900 can also be installed in the first channel 100 to heat the cold air entering the first channel 100 by using the heating device 900, so that the air entering the inner tank from the first channel 100 is at a relatively high temperature. Thus, the drying effect in the inner tank can be optimized.

[0056] Specifically, a PTC heater, a heating wire or a heating tube can be used as the above-mentioned heating device 900.

[0057] The above-mentioned heating device 900 can be fixed on the side plate 800.

[0058] Specifically, the air outlet end of the first air duct of the drying device can be communicated with the bottom of the dishwasher inner tank, and the air inlet end of the third air duct of the drying device can be communicated with the top of the dishwasher inner tank.

[0059] Correspondingly, this embodiment also provides a dishwasher, which includes the above-mentioned drying device.

[0060] Therefore, the dishwasher provided in this embodiment has all the advantages of the above-mentioned drying device, is not prone to breeding bacteria and generating peculiar smells. Furthermore, the tableware in the dishwasher inner tank is not easily contaminated; in addition, it also has the advantages of low cost and low energy consumption.

[0061] In summary, the present invention discloses a drying device and a dishwasher, which overcome many technical defects of traditional dishwashers. The drying device and the dishwasher provided in this embodiment can make it not easy to breed bacteria and generate peculiar smells in the dishwasher inner tank. Furthermore, the tableware in the inner tank is not easily contaminated. In addition, it also has the advantages of low cost and low energy consumption.

[0062] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
