[0036] Embodiment 1

[0037] like Figures 1 to 5 As shown, this embodiment provides a washing device, wherein the washing device can be a dishwasher. In other embodiments, the washing device can be a device for washing other items, but is not limited thereto.

[0038] For ease of understanding, a dishwasher is used as an example for explanation. In this embodiment, the dishwasher includes a base 100, an inner tank 200, a washing component 300 and a heat pump component 400, wherein the inner tank 200 is arranged above the base 100; the washing component 300 includes a washing pipeline 310, and the washing pipeline 310 is used to supply washing water to flow into the inner tank 200; the heat pump component 400 includes an evaporator 410, a compression pump 420, a condenser 430 and a throttling device 440 connected in a closed loop in sequence, and a refrigerant pipe 450 for circulating refrigerant is connected between the evaporator 410 and the compression pump 420, the evaporator 410 is arranged on the peripheral side of the inner tank 200, and the condenser 430 is located at the bottom of the inner tank 200 and is used to heat the washing water in the washing pipeline 310.

[0039] In the above arrangement, the various components of the heat pump assembly 400 are dispersedly arranged, wherein the condenser 430 is arranged at the bottom of the inner tank 200 for heating the washing water in the washing pipeline 310, and the larger evaporator 410 is arranged on the peripheral side of the inner tank 200, thereby reducing the overall height of the dishwasher, thereby helping to save kitchen space and improve user experience.

[0040] Considering that in the existing dishwasher, other structures such as the respirator 110 are installed on the left side of the inner tank 200 , in some embodiments, the evaporator 410 is disposed on the right side of the inner tank 200 .

[0041] In some embodiments, when in use, if the kitchen stove is wide, that is, the distance between the wall and the staff is large, the evaporator 410 can be set at the rear side of the inner pot 200. In some embodiments, if the opening of the inner pot 200 is not on the front side, the evaporator 410 can also be set at the front side of the inner pot 200.

[0042] In order to improve the heat absorption efficiency of the evaporator 410, in some embodiments, the washing assembly 300 includes a box 411, the evaporator 410 is placed in the box 411, the box 411 is installed on the right side of the inner tank 200, and the box 411 can hold a heat exchange liquid. The above arrangement ensures that the box 411 does not occupy the overall height of the dishwasher, and can be used in a kitchen with a narrow stove. A water level sensor 412 is provided in the box 411, and the water level sensor 412 is used to detect the heat exchange liquid in the box 411. In some embodiments, the heat exchange liquid can be water.

[0043] In some embodiments, the box body 411 is fitted with the inner liner 200. Specifically, the box body 411 is a flat structure, and the side wall with the largest area is fitted with the inner liner 200. The above arrangement helps to improve the efficiency of the box body 411 in absorbing heat from the inner liner 200, and further improves the ability to supply heat to the evaporator 410. The box body 411 is provided with a first channel 413, and the inner liner 200 is provided with a second channel. The first channel 413 and the second channel are directly opposite, and the box body 411 and the inner liner 200 are connected through the first channel 413 and the second channel. In the height direction of the dishwasher, the position of the first channel 413 is located above the middle position of the box body 411. The above arrangement can ensure the volume of the box body 411.

[0044] The box body 411 is provided with a water tank inlet and a water tank outlet, the water tank inlet is connected to the external water pipe 130, the water tank outlet is connected to the inner tank 200 through the drain pipe 120, and the drain pipe 120 is connected in series with a drain valve 121. When the water in the box body 411 needs to be replaced, the drain valve 121 is opened, so that the water in the box body 411 flows into the inner tank 200 and is discharged from the inner tank 200.

[0045] Further, the inner tank 200 is provided with a water inlet, the water outlet end of the external water pipe 130 is connected to the inlet of the three-way valve 131, one water outlet of the three-way valve 131 is connected to the water tank inlet through a first pipe 132, and the other water outlet of the three-way valve 131 is connected to the water inlet through a second pipe 133. The three-way valve 131 has two working states. When the three-way valve 131 is in the first state, the external water pipe 130 is connected to the inner tank 200, and when the three-way valve 131 is in the second state, the external water pipe 130 is connected to the box body 411.

[0046] In this embodiment, the compression pump 420 is arranged on the base 100 and is located below the inner tank 200. The refrigerant pipe 450 between the evaporator 410 and the compression pump 420 is partially passed through the gap between the base 100 and the inner tank 200. The arrangement of the refrigerant pipe 450 helps to save the length of the refrigerant pipe 450 on the one hand; on the other hand, the height of the dishwasher will not be increased. Since the base 100 of the existing dishwasher has enough space to accommodate the compression pump 420, the placement of the compression pump 420 does not increase the height of the dishwasher.

[0047] During assembly, the evaporator 410 needs to be set on the base 100 first, and then the base 100 connected with the evaporator 410 is transferred to another station for assembly of other workpieces. In some embodiments, one end of the refrigerant tube 450 is located below the inner tank 200, and the other end of the refrigerant tube 450 is located on the peripheral side of the inner tank 200, and at least the refrigerant tube 450 is a flexible tube at the corner of the inner tank 200. In other words, at least the refrigerant tube 450 is a rubber tube at the corner of the inner tank 200, which can be elastically bent and deformed. The above arrangement allows the dishwasher to place the evaporator 410 flat on the base 100 during assembly and turnover, so as to reduce the height of the evaporator 410, reduce the occupied space, and improve the safety of the evaporator 410.

[0048] In this embodiment, the condenser 430 includes adjacent washing chamber 431 and refrigerant chamber 432. The washing chamber 431 is connected in series to the washing pipeline 310. The refrigerant chamber 432 is used to circulate the refrigerant. The refrigerant chamber 432 is connected in series between the compression pump 420 and the throttling device 440. The condenser 430 integrates the washing chamber 431 and the refrigerant chamber 432, thereby reducing the number of parts, simplifying the installation process, and improving assembly efficiency.

[0049] To improve the heating efficiency of the washing water, in some embodiments, the refrigerant cavity 432 surrounds the outer circumference of the washing cavity 431 .

[0050] Furthermore, the condenser 430 includes a first side wall 433 and a second side wall 434, the first side wall 433 is cylindrical and encloses a washing cavity 431, the second side wall 434 is cylindrical and covers the outer periphery of the first side wall 433, and the first side wall 433 and the second side wall 434 enclose a refrigerant cavity 432. The above arrangement allows only one layer of the first side wall 433 to separate the refrigerant cavity 432 and the washing cavity 431, which is conducive to improving the heat exchange efficiency.

[0051] Furthermore, the condenser 430 includes a flow divider 435, which is disposed between the first side wall 433 and the second side wall 434 and spirally wound around the periphery of the axis of the washing cavity 431, and divides the refrigerant cavity 432 into a spiral flow channel. The above arrangement allows the refrigerant to spirally wind around the periphery of the washing cavity 431 after entering the refrigerant cavity 432, thereby making the heat exchange between the refrigerant and the washing water more uniform and thorough.

[0052] A water cup 210 is disposed below the inner liner 200 , and the water cup 210 is used to collect the liquid in the inner liner 200 .

[0053] Regarding the series connection of the condenser 430, in some embodiments, the washing pipeline 310 includes a first connecting tube, a second connecting tube and a third connecting tube, the first connecting tube is connected between the water cup 210 and the washing cavity 431, the second connecting tube is connected between the washing cavity 431 and the water pump 220, and the third connecting tube is connected between the water pump 220 and the spray arm 320 of the washing component 300.

[0054] The condenser 430 is installed between the water outlet of the water cup 210 and the water pump 220, making full use of the structure of the existing dishwasher without changing the original structural layout.

[0055] Specifically, the condenser 430 has a first inlet and a first outlet connected to the washing cavity 431, one end of the first connecting tube is connected to the water cup 210, and the other end is connected to the first inlet, one end of the second connecting tube is connected to the first outlet, and the other end is connected to the water inlet of the water pump 220, one end of the third connecting tube is connected to the water outlet of the water pump 220, and the other end is connected to the inlet of the spray arm 320.

[0056] The bottom of the water cup 210 is provided with a water outlet, one end of the waste water pipe 230 is connected to the water outlet, and the other end is connected to the downpipe outside the dishwasher. The waste water pipe 230 is connected in series with a waste water pump 240 for discharging water in the inner tank 200.

[0057] 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.
