[0034] like Figure 1 As shown, this embodiment provides a dishwasher, including a base 30, an inner tub 10, a spray mechanism, and a heat pump assembly 40. The inner tub 10 is disposed above and fixed to the base 30, and a washing chamber is formed inside the inner tub 10. A loading / unloading port is provided on the front side of the inner tub 10, through which tableware or cookware to be washed can be placed into the washing chamber. At least the spraying end of the spray mechanism is located inside the washing chamber, and the spray mechanism is used to spray washing water into the washing chamber; the heat pump assembly 40 is used to heat the washing water. When the dishwasher is operating, the washing water is heated by the heat pump assembly 40 and then enters the spray mechanism, and is sprayed onto the tableware or cookware to be washed, achieving the purpose of cleaning.

[0035] The heat pump assembly 40 includes a compressor 42, an evaporator 41, and a condenser. The evaporator 41, compressor 42, and condenser are connected end-to-end to form a circulating medium channel for heat exchange. The heat exchange medium in the circulating heat exchange channel can exchange heat with the wash water to transfer heat to the wash water, thereby heating the wash water. Specifically, the evaporator 41 absorbs heat from the environment to raise the temperature of the refrigerant. The heated refrigerant is then compressed by the compressor 42 to obtain a high-temperature, high-pressure refrigerant. The high-temperature, high-pressure refrigerant enters the condenser and exchanges heat with the wash water, thereby heating the wash water.

[0036] In this embodiment, the heat pump assembly 40 is disposed on the base 30 and located below the inner liner 10. The heat pump assembly 40 is installed using the space between the base 30 and the inner liner 10, resulting in a compact structure that makes efficient use of the dishwasher's internal space.

[0037] In existing technologies, fixing the evaporator 41 generally requires adding two plastic housings, which are fitted onto the evaporator 41 and fixed to the base 30. This fixing method occupies a large space, is costly, and makes the disassembly and assembly of the evaporator 41 complex, time-consuming, and inconvenient for after-sales maintenance.

[0038] To solve the above problems, in this embodiment, a decorative piece 20 is provided between the inner liner 10 and the base 30 to cover the gap. The decorative piece 20 and the base 30 cooperate to restrict the position of the evaporator 41, so as to fix the evaporator 41, save space, and do not require additional parts, which is low in cost and easy to disassemble and assemble.

[0039] Specifically, the decorative piece 20 is detachably connected to the front bottom of the inner tank 10, and the bottom end of the decorative piece 20 extends to the base 30 to cover the assembly gap between the inner tank 10 and the base 30, thereby enhancing the appearance. The decorative piece 20 is located between the evaporator 41 and the base 30, meaning that the decorative piece 20 and the base 30 are arranged vertically, and the two work together to restrict the position of the evaporator 41, thus fixing the evaporator 41 without the need for additional structures to fix the evaporator 41, reducing the number of dishwasher parts and helping to reduce costs. When maintenance of the evaporator 41 is required, only the decorative piece 20 needs to be removed to expose the evaporator 41, thus facilitating after-sales maintenance.

[0040] To improve the fixing effect of the evaporator 41, the decorative part 20 is provided with a positioning structure. The positioning structure is used to cooperate with the evaporator 41 to limit the position of the evaporator 41 and improve the fixing effect of the evaporator 41.

[0041] In this embodiment, the positioning structure on the decorative part 20 is a limiting groove. The top end of the evaporator 41 can extend into the limiting groove. The limiting groove restricts the position of the top end of the evaporator 41, thereby achieving the effect of overall positioning and fixing of the evaporator 41.

[0042] Optionally, the limiting groove can be configured as a contour groove of the evaporator 41, that is, the shape of the limiting groove can be adapted to the outer contour shape of the top of the evaporator 41. For example, the evaporator 41 is generally rectangular, and correspondingly, the limiting groove is a rectangular groove. The size of the rectangular groove is equal to or slightly larger than the size of the top of the evaporator 41, so as to improve the positioning effect of the evaporator 41.

[0043] In other embodiments, the positioning structure on the decorative element 20 may be a protrusion that mates with the evaporator 41. Exemplarily, the positioning structure on the decorative element 20 includes a plurality of protrusions arranged circumferentially around the evaporator 41, the plurality of protrusions surrounding a space that accommodates the top end of the evaporator 41 for positioning and fixing the evaporator 41.

[0044] In this embodiment, as Figure 2 As shown, the decorative component 20 includes an upper blocking portion 21, a connecting portion 22, and a positioning portion 23. The upper blocking portion 21 is used to connect to the inner liner 10, and extends from top to bottom and rearward. The top end of the connecting portion 22 is connected to the upper blocking portion 21, and the bottom end of the connecting portion 22 is connected to the positioning portion 23. The connecting portion 22 extends generally vertically. The positioning portion 23 extends forward from the connecting portion 22, and the front end of the positioning portion 23 is connected to the base 30. The positioning portion 23 is used to abut against the evaporator 41.

[0045] Specifically, the top of the upper shield 21 is located at the front side of the bottom end of the inner liner 10 and is connected to the inner liner 10. The upper shield 21 extends rearward, providing installation space for the positioning part 23 in the front-rear direction, facilitating the engagement of the positioning part 23 with the evaporator 41. The connecting part 22 extends approximately vertically, covering the gap between the inner liner 10 and the base 30, as well as structural components. The positioning part 23 extends from back to front, covering the top of the evaporator 41 so that it abuts against the evaporator 41, and also connecting the edge of the base 30, thereby decorating the space between the inner liner 10 and the base 30.

[0046] To facilitate the assembly and disassembly of the decorative element 20, the top end of the decorative element 20 can be fixed to the inner liner 10 using fasteners such as screws. In some embodiments, the top end of the decorative element 20 can be fixed to the inner liner 10 by snap-fit ​​or magnetic adsorption.

[0047] like Figure 1 As shown, a fixing member 11 is provided on the inner liner 10. The fixing member 11 extends downward from the inner liner 10 and is used for detachable connection with the base 30 to fix the inner liner 10 to the base 30. For example, the fixing member 11 can be a fixing plate. The base 30 is provided with a plug-in groove, and the fixing plate can be inserted into the plug-in groove to fix the inner liner 10 above the base 30.

[0048] In this embodiment, the decorative part 20 and the fixing part 11 are detachably connected to avoid adding holes to the inner liner 10, which would affect the strength and sealing effect of the inner liner 10.

[0049] In some embodiments, the decorative element 20 may also be detachably connected to the base 30, for example by screws, or by snap-fit, plug-in or adsorption.

[0050] To improve the fixing effect of the evaporator 41, a positioning structure can be provided on the base 30. The positioning structure is used to cooperate with the evaporator 41 to limit the position of the evaporator 41 and improve the fixing effect of the evaporator 41.

[0051] Combination Figure 2 and Figure 3 As shown, the positioning structure on the base 30 includes multiple limiting members 31, which form a space to accommodate the bottom end of the evaporator 41. The bottom end of the evaporator 41 is inserted into this space to position the evaporator 41 in the horizontal direction and constrain the evaporator 41 to move in the horizontal direction.

[0052] Since condensate will form on the surface of the evaporator 41 during operation, in order to prevent condensate from entering the interior of the evaporator 41, the limiting member 31 includes a support part 311 and a limiting part 312 connected to each other. The support part 311 is disposed on the base 30 and is used to abut against the bottom surface of the evaporator 41 to lift the evaporator 41 away from the surface of the base 30. The limiting part 312 extends vertically and is used to abut against the circumferential side wall of the evaporator 41 to restrict the evaporator 41 from moving in the horizontal direction.

[0053] Optionally, each side wall of the evaporator 41 is provided with a limiting member 31 to fix the position of the evaporator 41 in the horizontal direction.

[0054] In this embodiment, the evaporator 41 is disposed at one end of the base 30 near the front side, so that the evaporator 41 is disposed close to the decorative piece 20, thereby facilitating the fixing of the evaporator 41 by the decorative piece 20 and the base 30.

[0055] In this embodiment, the dishwasher also includes a water tank assembly 50 and a washing pump. Both the water tank assembly 50 and the washing pump are mounted on the base 30 and located below the inner tank 10. The water tank assembly 50 includes a water tank and a water distribution valve. The water tank communicates with the washing chamber inside the inner tank 10 and is used to temporarily store washing water. The water distribution valve connects the water tank and the spray mechanism, and is used to distribute the washing water to the spray pipes of the spray mechanism according to a certain pattern and proportion. The inlet end of the washing pump is connected to the water tank, and the outlet end of the washing pump is connected to the condenser. The condenser is connected to the water distribution valve. The washing pump drives the washing water through the condenser, so that the washing water is heated in the condenser. The heated washing water enters the spray mechanism through the water distribution valve for spray cleaning.

[0056] Specifically, the condenser includes a first fluid channel and a second fluid channel. The outlet of the compressor 42 is connected to the inlet of the first fluid channel, the outlet of the first fluid channel is connected to the inlet of the evaporator 41, and the outlet of the evaporator 41 is connected to the inlet of the compressor 42, forming a circulating medium flow channel. The inlet of the washing pump is connected to the water tank, the outlet of the washing pump is connected to the inlet of the second fluid channel, and the outlet of the second fluid channel is connected to the water distribution valve, forming a circulating heating flow channel.

[0057] In this embodiment, the condenser includes a heat exchange tube, within which a first fluid channel and a second fluid channel are formed. The heat exchange tube is approximately U-shaped. The U-shape of the heat exchange tube reduces the footprint of the condenser and, by extending the length of the heat exchange tube, ensures sufficient heat exchange area to improve the heating effect on the washing water.

[0058] For example, the heat exchange tube includes an inner tube and an outer tube nested together, with a first fluid channel formed between the inner tube and the outer tube, and a second fluid channel formed inside the inner tube; or, a second fluid channel is formed between the inner tube and the outer tube, and a first fluid channel is formed inside the inner tube.

[0059] To facilitate drainage, the dishwasher also includes a drain pump connected to the sink. When activated, the drain pump drains water from the sink outside the dishwasher. For example, the inlet of the drain pump is connected to the sink, and the outlet of the drain pump extends to the outside of the dishwasher via a pipe.

[0060] It should be noted that the spraying mechanism, water distribution valve, compressor 42, evaporator 41, condenser, washing pump and drain pump are all existing technologies in the field, and will not be described in detail in this embodiment.
