[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] like Figures 1 to 6As shown, this embodiment provides a washing appliance. In this embodiment, the washing appliance can be a dishwasher. In other embodiments, the washing appliance can be a device for washing other objects to be washed. The present invention is not limited to this. For ease of understanding, the dishwasher in this embodiment is used as an example for explanation. The dishwasher includes a base 100, an inner tank 200, a water pump 300, a housing 400, an evaporator 500 and a fan 600, wherein the inner tank 200 is arranged above the base 100; the water pump 300 is arranged on the base 100, and the water pump 300 is used to pump washing water into the inner tank 200; the housing 400 is fixed to the inner tank 200, and the housing 400 has a containing cavity and a first inlet and a second inlet connected to the containing cavity; the second inlet of the housing 400 is connected to the tap water pipe 1000. The evaporator 500 is connected; the evaporator 500 is arranged in the accommodating cavity of the box body 400; the first inlet of the box body 400 is connected to the air outlet of the fan 600, and the air inlet of the fan 600 is connected to the outside atmosphere and away from the inner tank 200; the air blown into the box body 400 by the fan 600 and the tap water entering the box body 400 can provide heat for the evaporator 500; the evaporator 500 and the condenser 510 cooperate to heat the washing water entering the inner tank 200; the water pump 300 can directly heat the washing water.

[0046] The above-mentioned arrangement realizes three heating methods for washing water, and solves the problem of heating washing water by a single method through the water pump 300. Compared with direct heating by the water pump 300, heating washing water by heat from air and tap water is more energy-efficient and helps to achieve energy conservation and emission reduction.

[0047] When working, multiple working modes can be implemented according to the settings of the above structure. Next, different working modes are introduced in combination with different application scenarios.

[0048] In the first implementation of this embodiment, when the temperature of the tap water is lower than the indoor air temperature, illustratively, the temperature of the tap water is lower than the first preset temperature, and the air temperature is greater than or equal to the first preset temperature. In the above environment, heat is provided to the washing water in three stages. In the first stage, air is drawn into the box 400 by the fan 600, and the washing water is heated by the evaporator 500 and the condenser 510; in the second stage, tap water is injected into the box 400, and the washing water is directly heated by the water pump 300; in the third stage, when the tap water temperature rises to the second preset temperature, the water pump 300 stops heating the washing water, starts the evaporator 500 and the condenser 510, and heats the washing water.

[0049] In a second implementation manner of this embodiment, when the temperature of the tap water is greater than the first preset temperature, the tap water is directly used to provide heat to the evaporator 500 , and combined with the condenser 510 to heat the washing water.

[0050] In the third implementation mode of this embodiment, when the tap water and air temperatures are both lower than the first preset temperature, the washing water is heated in two stages, wherein, in the first stage, the washing water is heated by the water pump 300; in the second stage, tap water is injected into the box body 400, and after the temperature of the inner tank 200 rises, the tap water temperature in the box body 400 is heated to a temperature exceeding the second preset temperature, the water pump 300 stops heating the washing water, starts the evaporator 500 and the condenser 510, and heats the washing water.

[0051] The first preset temperature may be 15°C-25°C, and the second preset temperature may be 15°C-50°C.

[0052] It should be noted that the switching of the working modes in the above three embodiments can be automatically switched according to the temperature or manually switched. Among them, when automatically switching according to the temperature, it is necessary to set a temperature sensor to measure and compare the temperatures of the tap water and the air respectively. When it is necessary to manually switch the working mode, three buttons can be directly set, and the switching of different working modes can be achieved by pressing different buttons. Specifically, the working mode in the first embodiment can be applicable to winter, when the tap water temperature is low and the indoor temperature is high. The working mode in the second embodiment is applicable to summer, when the tap water temperature is high. The working mode in the third embodiment is applicable to winter, when the tap water temperature is low and the air temperature is low.

[0053] In order to reduce the cost of the dishwasher and simplify the working logic, in other embodiments, the heating function of the water pump 300 may not be provided, and only the fan 600 and tap water may be used to provide heat to the evaporator 500. Of course, in some embodiments, only the fan 600 may be provided or only tap water may be used to provide heat to the evaporator 500.

[0054] In order to reduce the height of the dishwasher, in some embodiments, the box body 400 is disposed on the peripheral side of the inner tank 200. In this embodiment, in order to improve the heat transfer efficiency, the box body 400 is fitted with the inner tank 200, and the temperature in the inner tank 200 can be transferred to the box body 400. The first side surface of the box body 400 is fitted with the second side surface of the inner tank 200, and the area of ​​the first side surface accounts for 20%-80% of the area of ​​the second side surface.

[0055] The fan 600 is arranged on the top wall of the inner liner 200, and the box 400 is installed on the side wall of the inner liner 200. A fluid channel is connected between the fan 600 and the box 400. The fluid channel is located at the corner of the inner liner 200, and the corner of the inner liner 200 where the fluid channel is installed is rounded. With the arrangement of the above structure, the large space at the corner of the inner liner 200 is effectively utilized. Without increasing the size of the whole machine, the cross-sectional area of ​​the fluid channel can be maximized, thereby maximizing the amount of air blown into the box 400. Among them, the corner of the fluid channel is prepared according to the corner of the inner liner 200.

[0056] The box body 400 includes a box bottom 410 and a cover body 420. The box bottom 410 is fixed to the side wall of the inner container 200. The cover body 420 is covered on the box bottom 410 and encloses a receiving cavity. The evaporator 500 is located in the receiving cavity. The above arrangement simplifies the manufacturing process of the box body 400, reduces the cost, and facilitates assembly.

[0057] The box body 400 further includes an air cover 430, which is arranged on the groove of the box bottom 410 to enclose a fluid channel, and the fluid channel is connected between the air outlet of the fan 600 and the first inlet of the box body 400. The box bottom 410 is provided with convex ribs 411 arranged at intervals, and a groove is formed between two convex ribs 411. The provision of the convex ribs 411 also helps to increase the structural strength of the box bottom 410.

[0058] The evaporator 500 includes a heat dissipation pipe, which is arranged in a serpentine shape in the accommodating chamber. The above arrangement can effectively increase the contact area between the evaporator 500 and the air or tap water in the accommodating chamber with limited space, thereby improving the heat exchange efficiency of the evaporator 500.

[0059] The evaporator 500 includes a plurality of fins, and the fins are arranged in the accommodating cavity at intervals. Specifically, the fins are arranged in the accommodating cavity at intervals. The above arrangement can effectively increase the surface area of ​​the evaporator 500 in the accommodating cavity with limited space, so that it can contact with more air or tap water, thereby improving the heat exchange efficiency of the evaporator 500.

[0060] In order to reasonably utilize the structure of the existing dishwasher and reduce the scope of modification, the compression pump 520 of the dishwasher is arranged on the base 100 and is located below the inner tank 200, and the condenser 510 of the dishwasher is arranged below the inner tank 200. Since the base 100 of the existing dishwasher has enough space to accommodate the compression pump 520 and the condenser 510, the placement of the condenser 510 and the compression pump 520 does not increase the height of the dishwasher.

[0061] The refrigerant pipe 530 between the evaporator 500 and the compression pump 520 is partially inserted into the gap between the base 100 and the inner tank 200. The arrangement of the refrigerant pipe 530 helps to save the length of the refrigerant pipe 530 and does not increase the height of the dishwasher.

[0062] A throttling device 540 is provided between the evaporator 500 and the condenser 510. It should be noted that the working principle of the evaporator 500, the condenser 510 and the compression pump 520 cooperating with each other to complete the heating of the washing water is well known to those skilled in the art, so it will not be repeated here.

[0063] During assembly, the evaporator 500 needs to be set on the base 100 first, and then the base 100 connected with the evaporator 500 is transferred to another station for assembly of other workpieces. One end of the refrigerant pipe 530 between the evaporator 500 and the compression pump 520 is located below the inner tank 200, and the other end of the refrigerant pipe 530 is located on the peripheral side of the inner tank 200, and at least the part of the refrigerant pipe 530 at the corner of the inner tank 200 is a flexible pipe. In other words, at least the refrigerant pipe 530 at the corner of the inner tank 200 is a rubber tube, and the rubber tube can be elastically bent and deformed. The above arrangement allows the dishwasher to place the evaporator 500 flat on the base 100 during assembly and turnover, so as to reduce the height of the evaporator 500, reduce the occupied space, and improve the safety of the evaporator 500.

[0064] To improve the air supply efficiency of the fan 600, in some embodiments, a plurality of fans 600 and a plurality of first inlets are provided, and the plurality of fans 600 are spaced apart in the inner tank 200, and the air outlet of each fan 600 is connected to the corresponding first inlet.

[0065] The water pump 300 pumps the washing water to the spray arm 320 in the inner tank 200 through the conduit 310. The spray arm 320 rotates to spray the washing water onto the dishes to be washed in the inner tank 200 to clean the stains.

[0066] Among them, an exhaust port is provided at the bottom of the box body 400, and the air blown into the box body 400 by the fan 600 can flow out from the exhaust port after cooling. Cooling means that the air cannot effectively provide heat to the evaporator 500. Exemplarily, the air in the box body 400 is discharged after the temperature is lower than 10°C or 15°C. A solenoid valve is provided at the exhaust port, and the solenoid valve controls the opening and closing of the exhaust port. When cold air needs to be discharged, the exhaust port is opened.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
