It can be understood that the specific embodiments described herein are only used to explain the utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0037] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements.

In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0040] This embodiment provides a heat pump dishwasher, including a body, a spray mechanism, a water pump, and a heat pump assembly. The body includes a base 200, an inner tub located above the base 200, and a water cup. A washing chamber is formed within the inner tub, which can hold tableware or cookware to be washed. The washing chamber is connected to the water cup. Both the water pump and the heat pump assembly are located on the base 200. The water inlet of the water pump is connected to the water cup, and the water outlet of the water pump is connected to the heat pump assembly. The heat pump assembly is connected to the water cup to form a heating circuit for the washing water. The heated washing water flows through the water cup to the spray mechanism, which sprays water into the washing chamber to clean the tableware or cookware. Heating the washing water with the heat pump assembly and then using the heated water to spray and clean the cookware or tableware results in good cleaning performance. The heat pump assembly has high energy efficiency, which helps reduce energy consumption.

[0041] The heat pump assembly includes a compressor, an evaporator, and a condenser. The evaporator, compressor, and condenser are sequentially connected to form a circulating heat exchange channel for the heat exchange medium. A washing water channel is provided within the condenser, and this channel is connected to both a water pump and a water cup. The heat exchange medium in the circulating heat exchange channel can exchange heat with the washing water in the washing water channel, transferring heat to the washing water and thus heating it.

[0042] When the dishwasher is running, the wash water is pressurized by the water pump and enters the wash water channel in the condenser, where it exchanges heat with the heat exchange medium. After being heated, the wash water returns to the water cup 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 returns to the water cup. This cycle continues until the washing process is complete.

[0043] The heat pump dishwasher also includes a computer board assembly 100, which is used to control the start and stop of modules such as the heat pump assembly inside the heat pump dishwasher, so that the modules inside the heat pump dishwasher can work together.

[0044] Because heat pump dishwashers increase the power load of compressors and other components, the computer board components 100 generate a lot of heat when they are working, and natural heat dissipation is no longer sufficient to meet the usage requirements.

[0045] To solve the above problems, such as Figure 1 As shown, in this embodiment, the computer board assembly 100 includes a computer board 20, a computer board housing, and a fan 30. The computer board 20 is disposed inside the computer board housing, which has a heat dissipation inlet and a heat dissipation outlet 114. The fan 30 is disposed on the computer board housing, and its air outlet 32 ​​is connected to the heat dissipation inlet. When the computer board assembly 100 is started, the fan 30 starts, driving the air outside the computer board housing through the heat dissipation inlet into the computer board housing to dissipate heat from the computer board 20. The air is then discharged outside the computer board housing through the heat dissipation outlet 114, so that the heat generated by the computer board 20 during operation is dissipated to the outside of the computer board housing with the airflow, thereby achieving the purpose of heat dissipation.

[0046] In this embodiment, the fan 30 is arranged to drive the air flow to force the air flow to flow to the computer board 20, so that the computer board 20 can be cooled at a high cooling efficiency, and the temperature of the computer board 20 can be quickly reduced, so that the computer board assembly 100 can meet the use requirements.

[0047] In order to avoid increasing the space occupied by the computer board assembly 100 after the fan 30 is arranged, the outer wall of the computer board box is concave to form a positioning groove 111, and the fan 30 is arranged in the positioning groove 111. Correspondingly, the heat dissipation inlet is arranged in the positioning groove 111, so that the air outlet 32 of the fan 30 and the heat dissipation inlet are in communication. By arranging the positioning groove 111, the space inside the computer board box can be used to install the fan 30, so that the influence of the fan 30 on the overall size of the computer board assembly 100 is reduced, so as to avoid affecting the overall size of the heat pump dishwasher.

[0048] Optionally, after the fan 30 is arranged in the positioning groove 111, the top surface of the fan 30 can be flush with the top surface of the computer board box, or slightly lower or higher than the top surface of the computer board box, so that the overall size of the computer board assembly 100 is basically the same as the size of the computer board box, so as to further reduce the size of the computer board assembly 100.

[0049] Optionally, the positioning groove 111 can be formed by bending the plate material in the computer board box. That is, the thickness of each side wall in the computer board box can be substantially the same, the outer wall of the computer board box forms the positioning groove 111, and the inner wall of the computer board box forms a protruding structure at the corresponding position, so as to avoid increasing the thickness of the plate material of the computer board box, thereby saving costs.

[0050] Specifically, the computer board 20 includes a circuit board 21 and a plurality of devices arranged on the circuit board 21. The heights of the devices in the computer board 20 are different. In order to avoid interference between the protruding structure formed on the inner wall of the computer board box at the corresponding position of the positioning groove 111 and the devices, the circuit board 21 is provided with a first mounting area and a second mounting area, the first mounting area is opposite to the positioning groove 111, and the height of the device on the first mounting area is lower than the height of the device on the second mounting area. By optimizing the mounting positions of the devices on the circuit board 21, the devices with a high height are staggered with the positioning groove 111, and the devices with a low height are arranged correspondingly with the positioning groove 111, so as to avoid structural interference, and the space on the circuit board 21 can be fully utilized.

[0051] In this embodiment, the positioning groove 111 is arranged at the top of the computer board box. In other embodiments, the positioning groove 111 can also be arranged at the side or bottom of the computer board box.

[0052] Optionally, the heat dissipation inlet is arranged on the circumferential side wall of the positioning groove 111. It can be understood that, since the positioning groove 111 is formed by concave in the side wall of the computer board box, the side wall of the positioning groove 111 extends downward from the top surface of the computer board box, and is arranged opposite to at least part of the devices on the circuit board 21. Arranging the heat dissipation inlet on the side wall of the positioning groove 111 can make the heat dissipation inlet opposite to at least part of the devices on the circuit board 21, so that the airflow entering the computer board box through the heat dissipation inlet can contact at least part of the devices, thereby improving the heat dissipation effect.

[0053] To improve the heat dissipation effect, the computer board 20 further comprises a heat dissipation fin 22 arranged on the circuit board 21, the heat dissipation fin 22 is opposite to the heat dissipation inlet, so that the airflow can pass through the heat dissipation fin 22 and better carry the heat generated by the computer board 20 out of the computer board box, thereby ensuring the heat dissipation effect.

[0054] To form convection in the computer board box to improve the heat dissipation effect, the heat dissipation inlet and the heat dissipation outlet 114 on the computer board box are opposite, that is, the heat dissipation fin 22 is located between the heat dissipation inlet and the heat dissipation outlet 114, and after the airflow carries heat through the heat dissipation fin 22, it is directly discharged through the heat dissipation outlet 114, thereby improving the ventilation effect of the computer board box to improve the heat dissipation effect.

[0055] In the embodiment, the axis of the fan 30 is perpendicular to the bottom surface of the positioning groove 111, the air inlet 31 of the fan 30 is arranged on the axial end surface of the fan 30, and the air outlet 32 of the fan 30 is arranged on the circumferential side wall of the fan 30. That is, the fan 30 is arranged transversely, the axial dimension of the fan 30 is small, thereby reducing the depth requirement of the positioning groove 111, making the structure of the computer board box and the fan 30 more compact, and being conducive to controlling the size of the computer board box.

[0056] To facilitate the after-sales maintenance of the computer board assembly 100, the fan 30 and the computer board box are detachably connected to facilitate assembly and disassembly.

[0057] In the embodiment, the fan 30 and the computer board box are clamped and fixed, which is convenient to disassemble and assemble, and the fixing structure is simple. Specifically, the first clamping arm 115 is formed on the side wall of the positioning groove 111 and extends upward, and the first clamping arm 115 can be clamped with the top of the fan 30 to limit the fan 30 in the positioning groove 111, avoiding the fan 30 from being separated from the positioning groove 111.

[0058] The first clamping arm 115 comprises a first extension arm, and a clamping protrusion is arranged at the top end of the first extension arm and faces one side of the positioning groove 111. When the fan 30 needs to be installed into the positioning groove 111, the fan 30 first contacts the clamping protrusion and exerts a force on the clamping protrusion, the force is transmitted to the first extension arm through the clamping protrusion, and the first extension arm is driven to bend and deform to the outside of the positioning groove 111 to avoid the fan 30, so that the fan 30 can be installed into the positioning groove 111 by passing the clamping protrusion; after the fan 30 enters the positioning groove 111, the force of the fan 30 on the first extension arm gradually decreases, the first extension arm resets, the clamping protrusion abuts against the top surface of the fan 30, and a downward force is exerted on the top surface of the fan 30 to prevent the fan 30 from separating from the positioning groove 111, thereby fixing the fan 30 and the computer board box.

[0059] Optionally, the clamping protrusion has a first guide inclined surface extending from the top to the bottom of the clamping protrusion, and the first guide inclined surface is inclined downward to the center of the positioning groove 111. In this way, when the fan 30 is installed, the fan 30 can slide along the first guide inclined surface, so that the fan 30 has a horizontal separation to the outside of the positioning groove 111, and the first extension arm is more easily bent and deformed.

[0060] In this embodiment, two first clamping arms 115 are arranged, one first clamping arm 115 is formed by extending upward from the side wall of the positioning groove 111, and the other first clamping arm 115 is arranged in the positioning groove 111, and the two first clamping arms 115 are oppositely arranged to respectively cooperate with the opposite two ends of the fan 30, so that the fixing effect is good.

[0061] In other embodiments, the number of first clamping arms 115 can be more than two, for example, three, four or more, and the first clamping arms 115 can all be formed by extending from the side wall of the positioning groove 111 or all be arranged in the positioning groove 111. The specific number and arrangement position can be adjusted according to actual needs, and this embodiment is not limited.

[0062] In order to reduce the assembly difficulty of the fan 30 and the computer board box, a positioning column 116 is arranged in the positioning groove 111, and a positioning hole is arranged on the fan 30, and the positioning column 116 is arranged in the positioning hole. When the fan 30 is installed, the positioning column 116 and the positioning hole are matched to realize the positioning of the fan 30 and the computer board box, the installation angle of the fan 30 is guided, the assembly difficulty is reduced, and the fixing effect of the fan 30 and the computer board box is improved.

[0063] In this embodiment, two positioning columns 116 are arranged and are diagonally arranged to improve the positioning effect of the fan 30. In other embodiments, the number and arrangement mode of the positioning column 116 can be adjusted according to actual needs.

[0064] In other embodiments, the positioning post 116 can be set on the fan 30, and correspondingly, the positioning hole is set on the computer board box, which can also realize the positioning of the fan 30 and the computer board box.

[0065] like Figure 1 As shown, the computer board box includes a detachable bottom shell 12 and a top cover 11, which form an inner cavity in which the computer board 20 is disposed. The detachable connection between the bottom shell 12 and the top cover 11 facilitates after-sales maintenance of the computer board 20 inside the inner cavity.

[0066] In this embodiment, the bottom shell 12 and the top cover 11 are snapped together and fixed, making assembly and disassembly convenient. Specifically, the top cover 11 is provided with a second snap-fit ​​arm 112, and the second snap-fit ​​arm 112 is provided with a snap-fit ​​hole 1121. The bottom shell 12 is provided with a snap-fit ​​protrusion 121. When assembling the top cover 11 and the bottom shell 12, the snap-fit ​​protrusion 121 is snapped into the snap-fit ​​hole 1121, thereby fixing the top cover 11 and the bottom shell 12 together.

[0067] like Figure 1 As shown, the bottom shell 12 includes a bottom plate and a first circumferential sidewall surrounding the circumferential edge of the bottom plate. The first circumferential sidewall is connected to the bottom plate to form a groove structure with an open top. A latching protrusion 121 is provided on the outer wall of the first circumferential sidewall. The top cover 11 includes a top plate and a second circumferential sidewall surrounding the circumferential edge of the top plate. The second circumferential sidewall is connected to the top plate. A second latching arm 112 is formed on the second circumferential sidewall. When the top cover 11 and the bottom shell 12 are assembled, the first circumferential sidewall is located inside the second circumferential sidewall, so that the latching hole 1121 on the second latching arm 112 can engage with the latching protrusion 121. This arrangement facilitates latching engagement and, on the other hand, guides the assembly of the top cover 11 and the bottom shell 12 through the nesting of the first and second circumferential sidewalls, achieving initial positioning of the top cover 11 and the bottom shell 12 and facilitating assembly.

[0068] Optionally, two opposing cracks 113 are provided on the second circumferential sidewall. The cracks 113 extend upward from the bottom surface of the second circumferential sidewall. The portion of the second circumferential sidewall located between the two cracks 113 forms a second snap-fit ​​arm 112. The second snap-fit ​​arm 112 is connected to the second circumferential sidewall only at its top and has a certain deformation capacity to facilitate the second snap-fit ​​arm 112 to cooperate and be fixed with the snap protrusion 121.

[0069] Optionally, at least two second snap-fit ​​arms 112 are formed on the second circumferential sidewall to increase the connection points between the top cover 11 and the bottom shell 12 and improve the fixing effect. For example, each side of the second circumferential sidewall is provided with at least one second snap-fit ​​arm 112. For example, the top plate is generally rectangular, and the second circumferential sidewall includes four sides, each side being provided with one or two second snap-fit ​​arms 112.

[0070] In some embodiments, the second clamping arm 112 can be arranged on the first circumferential side wall, and correspondingly, the clamping protrusion 121 can be arranged on the second circumferential side wall, and the first circumferential side wall can be nested outside the second circumferential side wall.

[0071] In order to enable the upper cover 11 to be mounted on the bottom shell 12 at a specified angle and to prevent mistaken assembly, one of the second circumferential side walls is provided with a positioning notch 117, and the first circumferential side wall is provided with a positioning protrusion 124 which is inserted into the positioning notch 117. Through the cooperation of the positioning protrusion and the positioning notch 117, on the one hand, the positioning of the upper cover 11 and the bottom shell 12 can be achieved, facilitating assembly; on the other hand, the positioning protrusion and the positioning notch 117 can prevent mistaken assembly, enabling the upper cover 11 and the bottom shell 12 to be assembled at a unique specified angle, and ensuring the positional relationship between the heat dissipation inlet and the heat dissipation fins 22 and between the positioning groove 111 and the first mounting area.

[0072] In some embodiments, the positioning notch 117 can be arranged on the first circumferential side wall, and correspondingly, the positioning protrusion 124 can be arranged on the second circumferential side wall.

[0073] In the present embodiment, the protruding ribs extending in the circumferential direction on the outer wall of the first circumferential side wall can abut against the bottom surface of the second circumferential side wall, so as to limit the nesting depth of the first circumferential side wall and the second circumferential side wall, avoid interference between the devices on the computer board 20 and the inner wall of the upper cover 11, and thus ensure the reliability of the computer board 20.

[0074] In order to simplify the structure, the positioning protrusion 124 can be formed by surrounding protruding ribs. For example, part of the protruding ribs are surrounded to form an inverted U-shaped structure, so as to form the positioning protrusion 124 which extends into the positioning notch 117. In other embodiments, the protruding ribs can be surrounded to form other shapes, as long as they can cooperate with the positioning notch 117.

[0075] In order to facilitate after-sales maintenance of the computer board 20, the computer board 20 can be detachably arranged in the computer board box. Specifically, at least two supporting members 125 are arranged in the computer board box, and the computer board 20 is lapped on the supporting members 125, so that the computer board 20 is arranged in a spaced manner with the bottom surface of the computer board box. The bottom surface of the computer board 20 can also be provided with devices, so as to avoid damage caused by bumping. A U-shaped hole is arranged on the circumferential side wall of the computer board box, and the part of the computer board box located in the U-shaped hole forms a resilient abutting arm 123. The resilient abutting arm 123 can abut against the computer board 20 on the supporting member 125, so as to fix the computer board 20 through the cooperation of the resilient abutting arm 123 and the supporting member 125. In the present embodiment, the supporting member 125 and the resilient abutting arm 123 are both located in the bottom shell 12.

[0076] In order to improve the fixing effect of the resilient abutting wall on the computer board 20, a thickened portion is formed at the bottom end of the resilient abutting wall, and the thickened portion protrudes towards the inside of the computer board box, so as to increase the contact area between the resilient abutting arm 123 and the computer board 20, thereby reducing the stress received by the computer board 20.

[0077] Optionally, the side of the thickening part facing the inner side of the computer board box is provided with a second guide slope, which is inclined from top to bottom towards the inner side of the computer board box. When the computer board 20 is installed, the edge of the computer board 20 abuts against the second guide slope and slides along the second guide slope. The computer board 20 has a horizontal force on the second guide slope towards the outer side of the computer board box, which can push the elastic abutting arm 123 to bend and deform towards the outer side of the computer board box, so that the computer board 20 can move to the lower side of the elastic abutting arm 123 by passing the thickening part, and the assembly is completed.

[0078] In order to facilitate the after-sales maintenance of the computer board assembly 100 as a whole, the computer board assembly 100 and the base 200 are detachably connected. As shown in Figure 1 and Figure 2 The outer wall of the bottom shell 12 is provided with a fixing part 122, which is fixedly connected with the base 200 by a fastener. Optionally, the fastener can be a screw.

[0079] Since the inner container is located above the base 200 and blocks most of the structure of the base 200, in order to disassemble and assemble the computer board assembly 100 separately without disassembling the whole machine, in the embodiment, the base 200 surrounds a mounting slot, and the sidewall of the base 200 is provided with a mounting port 201, the computer board assembly 100 can be mounted into the mounting slot through the mounting port 201, and the fixing part 122 is fixed with the edge of the mounting port 201, so as to facilitate the disassembly and assembly of the computer board assembly 100 on the outer side of the base 200.

[0080] In order to further improve the heat dissipation effect, in the embodiment, the air inlet 31 of the fan 30 and the heat dissipation outlet 114 are both in communication with the outer side of the base 200. Specifically, the air inlet 31 of the fan 30 and the heat dissipation outlet 114 are both in communication with the mounting port 201, so that the airflow in the heat dissipation process enters and exits through the mounting port 201, reducing the number of openings on the base 200, and at the same time, the airflow carrying heat can be discharged out of the base 200, so as to avoid affecting the temperature of other structures in the base 200.

[0081] Since the top end surface of the fan 30 is the air inlet 31, in order to facilitate the external airflow of the base 200 to be attracted by the fan 30, the inner wall of the mounting port 201 is provided with a rib plate 202, which abuts against the outer wall of the computer board box, so as to form an air inlet gap between the computer board box and at least part of the inner wall of the mounting port 201, and the air inlet 31 of the fan 30 is in communication with the air inlet gap.

[0082] In the embodiment, the rib plate 202 is arranged on the top inner wall of the mounting hole, so that the air inlet gap is located at the top of the computer board box, facilitating the communication between the air inlet gap and the air inlet 31 of the top surface of the fan 30.

[0083] Optionally, the installation opening 201 is provided with a plurality of parallel and spaced apart rib plates 202, the plurality of rib plates 202 extend along the through direction of the installation opening 201, the plurality of rib plates 202 can form the air inlet gap and improve the uniformity of the force acting on the computer board box, and improve the stability of the computer board box.

[0084] In some embodiments, the rib plate 202 can be arranged on the computer board box, and the rib plate 202 abuts against the installation opening 201 to form the air inlet gap.

[0085] In order to facilitate the air flow carrying heat to pass through the installation opening 201 and discharge outside the base 200, the heat dissipation outlet 114 on the computer board box is arranged on the side wall of the computer board box facing the installation opening 201, so that the heat dissipation outlet 114 can be located in the installation opening 201 to facilitate the discharge of the heat dissipation air flow. In the embodiment, the installation opening 201 is located on the rear side of the base 200, that is, the side of the heat pump dishwasher away from the machine door, and correspondingly, the heat dissipation outlet 114 is located on the rear side wall of the computer board box.

[0086] Optionally, the heat pump dishwasher further comprises a temperature detection member for detecting the ambient temperature outside the computer board box, and the computer board 20 is electrically connected with the temperature detection member, the heat pump assembly and the fan 30 to control the working parameters of the heat pump assembly and the fan 30.

[0087] For example, when the temperature detection member detects that the ambient temperature around the computer board box is high, the working frequency or heating rate of the heat pump assembly is reduced to reduce the heat dissipation to the surrounding environment when the heat pump assembly is working, so as to reduce the temperature of the working environment of the computer board 20, avoid the computer board 20 from malfunctioning due to the too high ambient temperature, and improve the reliability of the computer board 20.

[0088] For example, when the temperature detection member detects that the ambient temperature around the computer board box is low, the heat pump assembly generates less heat, that is, the power frequency or heating rate of the heat pump assembly is low, or the heat pump assembly is not started, at this time, the load of the computer board 20 is small, and the heat generated by the working of the computer board 20 is small, and the fan 30 can not be started, or the fan 30 is controlled to start at a low frequency power, so as to reduce the power consumption and reduce the noise.

[0089] Optionally, the temperature detection member can be a temperature sensing resistor or other structure capable of detecting temperature.
