[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment provides a dishwasher, including an inner tub, a water collection assembly 10, a spray mechanism, and a heat pump assembly. A washing chamber is formed within the inner tub, which can hold tableware or cookware to be washed. At least one spray end of the spray mechanism is located within the washing chamber, and the spray mechanism is used to spray washing water into the washing chamber. The water collection assembly 10 includes a water cup and a water distribution valve 12. The water cup is located below the inner tub and communicates with the washing chamber. The water distribution valve 12 is connected to both the water cup and the spray mechanism. The heat pump assembly and the water collection assembly 10 form a circulating heating channel. When the dishwasher is operating, the washing water first enters the water cup, is heated by the circulating heating channel, flows to the water distribution valve 12, and then enters the spray mechanism to spray the tableware or cookware in the washing chamber. The washing water on the tableware or cookware flows to the bottom of the washing chamber and returns to the water cup. This cycle is repeated to achieve water recycling and improve water utilization.

[0047] The heat pump assembly includes a compressor, an evaporator, and a condenser module. The evaporator, compressor, and condenser module are connected in sequence to form a circulating heat exchange channel for the heat exchange medium. The heat exchange medium in the circulating heat exchange channel can exchange heat with the washing water to transfer heat to the washing water and achieve the function of heating the washing water.

[0048] When the dishwasher is running, the wash water enters the condenser module and exchanges heat with the heat exchange medium in the condenser module. After being heated, the wash water enters the water distribution valve 12 and then enters the spray mechanism. The spray mechanism sprays the wash water onto the dishes or cookware in the washing chamber. The wash water on the dishes or cookware collects at the bottom of the washing chamber and flows back into the water cup. This cycle continues until the washing process is complete.

[0049] Since both the washing water and the heat exchange medium need to pass through the condenser module, and the condenser module is connected to refrigerant pipes to realize the entry and exit of the heat exchange medium, it occupies a large space, encroaches on the placement space of other parts, reduces the product's functional expandability, and makes installation relatively complicated.

[0050] To solve the above problems, such as Figures 1-3As shown, in this embodiment, the condenser module includes a condenser 20, a support member 30, and refrigerant pipes. The condenser 20 includes a first fluid channel and a second fluid channel. The first fluid channel is connected to the water collection assembly 10 so that washing water enters the first fluid channel for heating. The inlet and outlet ends of the second fluid channel are connected to the compressor and evaporator respectively via refrigerant pipes to form a circulating heat exchange channel, allowing the heat exchange medium to enter the second fluid channel to heat the washing water. The support member 30 supports and elevates the condenser 20 so that at least a portion of the space below the condenser 20 forms an installation space, within which at least a portion of the refrigerant pipes are installed. By elevating the condenser 20 and utilizing the space below it to place the refrigerant pipes, compared to the prior art where the refrigerant pipes and condenser 20 are laid flat, the horizontal space occupied by the condenser module within the dishwasher can be reduced, resulting in a more compact structure. This avoids affecting the placement space of other components, facilitates product functional expansion, and simplifies installation.

[0051] In addition, raising the condenser 20 can reduce the distance between the condenser 20 and the water collection assembly 10, making it easier for the two to connect, reducing the length of the pipe between them, which helps to save space and reduce costs.

[0052] Specifically, the dishwasher includes a base 70, an inner tub disposed above the base 70, and a support member 30 disposed on the base 70. The support member 30 is capable of lifting the condenser 20 off the surface of the base 70, so that the condenser 20 is located above the base 70, and there is a gap below the condenser 20 to form an installation space.

[0053] In this embodiment, the support member 30 includes a base plate 31 and a support part 32. The base plate 31 is disposed on the base 70, and the support part 32 protrudes from the base plate 31. The bottom end of the support part 32 is connected to the base plate 31, and the top end of the support part 32 supports the condenser 20. An installation space is formed between the condenser 20 and the base plate 31.

[0054] Optionally, the base plate 31 can be fixed to the base 70 to improve the stability of the condenser module. For example, the base plate 31 can be fixed to the base 70 by fasteners such as screws, or the base plate 31 can also be fixed to the base 70 by snap-fit ​​or magnetic adsorption.

[0055] In order to create an installation space below at least part of the condenser 20, the top of the support 32 contacts only a portion of the surface of the condenser 20, so that the part of the condenser 20 that does not contact the support 32 is suspended, thereby creating an installation space.

[0056] In this embodiment, the support 32 is a support plate with a relatively small thickness, so that the area of ​​the condenser 20 that is not in contact with the support plate is large, thereby forming a larger installation space. To reduce costs, the support plate can be a hollow structure to reduce material usage and the weight of the support 30.

[0057] To improve the support effect of the support member 30 on the condenser 20, two support parts 32 are provided. The two support parts 32 are parallel and spaced apart. The two support parts 32 work together to support the condenser 20 to prevent the condenser 20 from shaking.

[0058] In other embodiments, the number of support portions 32 may be three, four or more, and the specific number of support portions 32 may be set according to actual needs.

[0059] like Figure 1 and Figure 2 As shown, the condenser 20 includes heat exchange tubes, each comprising at least two main heat exchange sections arranged in parallel and a connecting section connecting adjacent main heat exchange sections. A support section 32 is perpendicular to the main heat exchange sections and can support all the main heat exchange sections. This configuration allows the heat exchange tubes to have a curved structure, which reduces the size of the heat exchange tubes while ensuring sufficient contact area for heat exchange. This, in turn, reduces the footprint of the condenser 20.

[0060] In this embodiment, there are two main heat exchange sections. The connecting part connects the same end of the two main heat exchange sections, so that the heat exchange tube is roughly U-shaped. The main heat exchange section extends along the first direction, and the two main heat exchange sections are arranged along the second direction. The supporting part 32 extends along the second direction to support the two main heat exchange sections.

[0061] To improve the stability of the condenser 20, a positioning groove is provided at the top of the support 32 corresponding to each main heat exchange section. The main heat exchange section is located in the positioning groove to make the position of the condenser 20 more stable. Specifically, two positioning grooves are provided at intervals on each support 32, and each positioning groove corresponds to one main heat exchange section.

[0062] Optionally, the shape of the positioning groove is adapted to the shape of the main heat exchange section to improve the positioning and support effect. For example, the main heat exchange section is cylindrical, and correspondingly, the positioning groove is an arc-shaped groove.

[0063] To ensure the stability of the condenser 20's position, the condenser module also includes a fixing member 40. The fixing member 40 is detachably connected to the support member 30, and the condenser 20 is clamped and fixed between the fixing member 40 and the support member 30. When installing the condenser 20, first place the condenser 20 on the support member 30, insert the two main heat exchange sections into their corresponding positioning slots, and then connect the fixing member 40 to the support member 30 to fix the condenser 20 and improve its stability.

[0064] Optionally, the fastener 40 includes a semi-ring structure, which is fitted around the main heat exchange section and clamps the condenser 20 onto the support 30, providing a good fixing effect. The semi-ring structure is adapted to the outer contour shape of the main heat exchange section, increasing the contact area between the semi-ring structure and the main heat exchange section and improving the fixing effect.

[0065] In this embodiment, the condenser 20 includes two main heat exchange sections. Correspondingly, the fixing member 40 includes two semi-ring structures. The two semi-ring structures can be an integral structure or a separate structure, as long as they are fixed to the support member 30, thereby achieving the purpose of fixing the condenser 20.

[0066] like Figure 3 As shown, the support member 30 also includes a fixing post 33 protruding from the base plate 31. The fixing member 40 is connected to the fixing post 33 by fasteners to achieve a detachable connection between the fixing member 40 and the support member 30. Optionally, the fastener is a screw.

[0067] like Figure 3 and Figure 4 As shown, the refrigerant piping includes a medium inlet pipe 81a and a medium outlet pipe 81b. The medium inlet pipe 81a is connected to the inlet end of the second fluid channel and is used to connect to the compressor. The medium outlet pipe 81b is connected to the outlet end of the second fluid channel and is used to connect to the evaporator. The heat exchange medium enters the second fluid channel of the condenser 20 through the medium inlet pipe 81a, exchanges heat with the washing water, and then flows out through the medium outlet pipe 81b. To reduce the space occupied, at least a portion of the medium inlet pipe 81a and at least a portion of the medium outlet pipe 81b are located within the installation space to reduce the footprint of the condenser module.

[0068] Optionally, the refrigerant piping also includes a connecting pipe 82. For example... Figure 4 As shown, the heat exchange tubes form a second fluid branch within the main heat exchange section, and adjacent second fluid branches are connected by a connecting pipe 82 to form a second fluid channel. The connecting pipe 82 is located within the installation space to reduce the footprint of the condenser module.

[0069] Specifically, the heat exchange tube includes an inner tube 22 and an outer tube 21. The inner tube 22 includes at least two parallel main tube sections and a connecting tube section connecting two adjacent main tube sections. The outer tube 21 is sleeved outside the main tube sections. A first fluid channel is formed inside the inner tube 22, and a second fluid branch is formed between the main tube section and the outer tube 21. The connecting tube is connected to the outer tube 21.

[0070] To improve the heat exchange efficiency between the washing water and the heat exchange medium, the inner tube 22 can be made of metal, as metal has good thermal conductivity, which is beneficial for improving heat exchange efficiency. Optionally, the inner tube 22 can be made of copper. Optionally, the outer tube 21 can be a corrugated pipe.

[0071] To facilitate the placement of the medium inflow pipe 81a, medium outflow pipe 81b, and connecting pipe 82 within the installation space, a medium inlet, a medium outlet, and a connecting port are provided on the side of the heat exchange tube facing the support member 30. The medium inlet is connected to the medium inflow pipe 81a, the medium outlet is connected to the medium outflow pipe 81b, and the connecting port is connected to the connecting pipe 82, so that the medium inflow pipe 81a, medium outflow pipe 81b, and connecting pipe 82 are located below the condenser 20, thus facilitating their placement within the installation space.

[0072] To ensure that the washing water can flow in the circulating heating channel, the dishwasher also includes a washing pump 60, which is connected to the condenser 20 and the water cup to drive the flow of washing water.

[0073] In this embodiment, the washing pump 60 is located between the outlet of the water cup and the inlet of the first fluid channel in the condenser 20, which helps to improve the driving effect of the washing pump 60 on the washing water in the water cup. In other embodiments, the washing pump 60 can be located between the water distribution valve 12 and the outlet of the first fluid channel in the condenser 20, which can also achieve the function of driving the flow of washing water.

[0074] like Figure 2 and Figure 3 As shown, the condenser module also includes a first hose 51 and a second hose 52. The first hose 51 connects the inlet end of the first fluid channel and the outlet of the washing pump 60, serving as the condenser's water inlet pipe; the second hose 52 connects the outlet end of the first fluid channel and the water distribution valve 12, serving as the condenser's water outlet pipe. By setting the first hose 51 and the second hose 52, the initial positioning of the condenser 20 can be achieved. Since the first hose 51 and the second hose 52 can deform within a certain range, they can also provide a certain amount of space for the condenser 20 to be placed on the support 30, ensuring that the condenser 20 can be placed on the support 30.

[0075] like Figure 2 As shown, in order to make the dishwasher structure more compact, the water cup is located on one side of the condenser 20 along the second direction, and the washing pump 60 is located on one side of the condenser 20 along the first direction. This arrangement can reduce the size of the water collection assembly 10, the condenser module and the washing pump 60 along the first and second directions, making the structure more compact.

[0076] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
