[0036] 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.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0040] like Figure 1 As shown, this embodiment provides a dishwasher, including a base structure, a housing, a door 20, an inner tub (not shown), a spray mechanism (not shown), and a heat pump assembly (not shown). The base structure is connected to the housing, forming a cavity with a front opening. The door 20 is movably connected to the housing to open or close the cavity. The spray mechanism, heat pump assembly, and inner tub are all disposed within the cavity. The inner tub is fixed to the base structure, forming a washing chamber. A loading / unloading port is provided on the front side of the inner tub, through which tableware or cookware to be washed can be placed into the washing chamber. At least the 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 heat pump assembly is located below the inner tub and is used to heat the washing water. When the dishwasher is operating, the washing water is heated by the heat pump assembly and enters the spray mechanism, and is then sprayed onto the tableware or cookware to be washed, achieving the purpose of cleaning.

[0041] The heat pump assembly includes a compressor, an evaporator 31, and a condenser. The evaporator 31, compressor, 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 31 absorbs heat from the environment to raise the temperature of the refrigerant. The heated refrigerant is then compressed by the compressor 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.

[0042] In order for the evaporator 31 to exchange heat with the ambient air, the base structure needs to be equipped with a vent, through which the low-temperature air after exchanging heat with the evaporator 31 is discharged.

[0043] Combination Figure 2 and Figure 3 As shown, the base structure includes a base 11, which is a groove structure with an open top. The heat pump assembly is installed inside the base 11. An inner vent 111 is provided on the front side of the base 11, which is directly opposite the evaporator 31 inside the base 11, so that the low-temperature air after heat exchange with the evaporator 31 can be discharged through the inner vent 111.

[0044] To ensure aesthetic appeal, users typically install a kickboard 12 on the front of the base 11 to match the interior environment. However, due to the operational requirements of the heat pump components, a custom-made, ventilated kickboard 12 is necessary, increasing costs.

[0045] To address the aforementioned issues, the base structure also includes a kick plate 12, which is positioned on the front side of the base 11. The kick plate 12 has an outer ventilation opening 1211 that communicates with the inner ventilation opening 111 to meet ventilation requirements. This base structure comes with a kick plate 12, eliminating the need for additional customization by the user and reducing customization costs.

[0046] To prevent the exhaust airflow from flowing freely between the kick plate 12 and the base 11 and affecting the exhaust efficiency, the kick plate 12 includes a circumferentially arranged air guide frame 122 surrounding the outer vent 1211. The air guide frame 122 extends from front to back to pass through the inner vent 111 and contact the evaporator 31. By providing the air guide frame 122, the airflow passing through the evaporator 31 can be directly guided through the air guide frame 122 and through the outer vent 1211, thereby improving the exhaust effect.

[0047] In addition, the air guide frame 122, in conjunction with the inner ventilation port 111, can also position the kick plate 12, improve the positioning accuracy of the kick plate 12, and facilitate the assembly of the kick plate 12 and the base 11.

[0048] In this embodiment, the evaporator 31 is provided with fins facing the outer ventilation port 1211, and the air guide frame 122 abuts against the fins. After sufficient heat exchange through the fins, the air directly enters the air guide frame 122, preventing the airflow from flowing arbitrarily between the base 11 or the base 11 and the kick plate 12, thus providing good airflow guidance and facilitating smooth exhaust.

[0049] In other embodiments, the outer vent 1211 can also be used as an air intake, that is, the outside air with a higher temperature comes into contact with the evaporator 31 through the outer vent 1211 and the air guide frame 122, exchanges heat and is then discharged.

[0050] In this embodiment, the kick plate 12 is provided with multiple through holes, which form an outer ventilation opening 1211. Specifically, the kick plate 12 includes a front plate 121, multiple through holes are provided on the front plate 121, and an air guide frame 122 is provided on the back of the front plate 121, with the multiple through holes located within the space enclosed by the air guide frame 122.

[0051] Compared to setting a single large through hole, setting multiple through holes to form an outer ventilation opening 1211 can not only meet the ventilation requirements, but also prevent large-sized debris from entering the base 11, thus avoiding affecting or damaging the normal operation of the internal structural components of the base 11.

[0052] Combination Figures 1-4 As shown in this embodiment, the through holes are hexagonal, and multiple through holes are arranged in multiple rows and columns, with adjacent rows of through holes staggered, so that the positions of the skirting board 12 with through holes have a honeycomb structure. This arrangement can make full use of space, increase the number of through holes, ensure ventilation, and also help improve the structural strength of the skirting board 12.

[0053] In other embodiments, the shape of the through hole can also be circular, triangular, or rectangular, etc., and the specific shape and arrangement can be set according to actual needs.

[0054] When the dishwasher door 20 is closed, it is positioned above the kick plate 12, with the front surface of the door 20 flush with the front surface of the kick plate 12 for improved appearance. When the door 20 is open, the top of the kick plate 12 is exposed, which can easily cause debris or water to fall between the front panel 121 and the base 11, and is also unsightly.

[0055] To solve the above problems, in this embodiment, the kick plate 12 also includes a top plate 123. The top plate 123 is connected to the top of the front plate 121 and extends from front to back. The top plate 123 can cover the gap between the front plate 121 and the base 11 from the top, so that the appearance of the door 20 is cleaner when it is opened, and prevents debris or water from falling between the front plate 121 and the base 11.

[0056] Optionally, the skirting board 12 also includes a base plate 125, which is connected to the bottom end of the front panel 121 and extends from front to back. By providing the base plate 125, the gap between the front panel 121 and the base 11 can be blocked from the bottom side, preventing debris from the indoor floor from entering between the front panel 121 and the base 11 from the bottom.

[0057] like Figure 4As shown, the base 11 also includes multiple stiffening plates 126, which are disposed on the back of the front plate 121 to improve the structural strength of the kick plate 12 and prevent it from being damaged by impacts. In this embodiment, the stiffening plates 126 extend vertically, and the multiple stiffening plates 126 are arranged horizontally. Some of the stiffening plates 126 connect the top plate 123 and the bottom plate 125, some connect the top plate 123 and the air guide frame 122, and some connect the bottom plate 125 and the air guide frame 122, thus avoiding the air guide frame 122.

[0058] In other embodiments, the number, extension direction, and arrangement of the stiffening plates 126 can be adjusted according to actual needs. For example, multiple stiffening plates 126 can be arranged in a cross pattern to improve the structural strength of the skirting board 12.

[0059] To facilitate replacement or cleaning of the baseboard 12, the baseboard 12 and the base 11 are detachably connected. Users can replace the baseboard 12 according to their interior decoration needs, or remove the baseboard 12 for cleaning.

[0060] The kickboard 12 also includes a fixing part 124, which is connected to the back of the front panel 121. Two fixing parts 124 are provided, one on each of the left and right ends of the front panel 121, making the kickboard 12 roughly U-shaped when viewed from above. The opening of the U-shaped kickboard 12 faces rearward. The fixing parts 124 are used to connect to the base 11. By providing two fixing parts 124 connected to the base 11, and with the fixing parts 124 located at the left and right ends of the front panel 121, the kickboard 12 can be evenly stressed, resulting in a good fixation between the kickboard 12 and the base 11.

[0061] To facilitate the assembly and disassembly of the kick plate 12, in this embodiment, the fixing part 124 is inserted into the base 11 and connected by fasteners. The insertion and engagement of the fixing part 124 and the base 11 enables the initial positioning of the kick plate 12 and the base 11, and, combined with the U-shaped structure of the kick plate 12, the operation is simple; the fasteners securely connect the fixing part 124 and the base 11, providing good fixation and convenient operation.

[0062] Combination Figure 2 and Figure 4 As shown, a connector 113 is provided on the base 11, and a connector groove 1241 is provided on the fixing part 124. During assembly, the kick plate 12 is placed on the front side of the base 11, and the connector 113 is aligned with the connector groove 1241. Then, the kick plate 12 is moved closer to the base 11 in the front-back direction, and the connector 113 is inserted into the connector groove 1241 to complete the positioning.

[0063] To make the base structure more aesthetically pleasing, clearance notches 112 are provided on both the left and right sides of the front end of the base 11. The clearance notches 112 are used to accommodate the fixing part 124 so that after the kick plate 12 is assembled with the base 11, the kick plate 12 and the base 11 form a more regular cuboid structure with a more beautiful appearance.

[0064] In this embodiment, the clearance notch 112 has a first surface extending in the front-back direction and a second surface extending in the left-right direction, and the connector 113 is disposed on the first surface. To ensure engagement with the connector slot 1241, the rear side of the connector slot 1241 and the side facing the wind guide frame 122 in the left-right direction are both open, so that when the kick plate 12 moves in the front-back direction, the connector 113 can smoothly enter the connector slot 1241. After the connector 113 engages with the connector slot 1241, it can position the kick plate 12 in the left-right direction, the front-back direction, and the up-down direction.

[0065] In some embodiments, the connector 113 may also be disposed on the second surface, and correspondingly, the connector slot 1241 may only form an opening on the rear side.

[0066] In some embodiments, the connector 113 may be disposed on the fixing part 124 or formed directly by the fixing part 124. Correspondingly, the insertion groove 1241 is disposed on the base 11, which can also realize the insertion positioning.

[0067] In this embodiment, the fastener is a screw, which passes through the fixing part 124 and engages with the plug 113 to fix the kick plate 12 to the base 11.

[0068] Alternatively, each fixing part 124 can be connected to the connector 113 by at least two screws to improve the fixing effect.

[0069] The fasteners cooperate with the fixing part 124. Since the fixing part 124 is on the side of the kick plate 12, when the dishwasher is installed indoors, the dishwasher is generally embedded in the kitchen cabinet. The fasteners can be covered by the cabinet, so that only the front panel 121 of the kick plate 12 is an external part, making the dishwasher more aesthetically pleasing.

[0070] In this embodiment, the kickboard 12 is a one-piece molded structure to reduce the number of parts, improve assembly efficiency, and reduce costs.

[0071] In some embodiments, such as Figure 5 As shown, the front panel 121 is provided with mounting holes, and the grille 127 is detachably installed in the mounting holes, forming an outer ventilation opening 1211. By setting the grille 127 to form the outer ventilation opening 1211, the grille 127 can realize ventilation and also block debris.

[0072] To facilitate cleaning of the grille 127 and reduce the intensity of disassembly and assembly, the grille 127 is detachably connected to the front panel 121, so as to facilitate the disassembly and cleaning of the grille 127.

[0073] like Figure 5 As shown, the grille plate 127 is snapped and fixed to the front plate 121. Exemplarily, the edge of the grille plate 127 is provided with at least two hooks 1271, which can engage with the slots on the back of the front plate 121 to fix the grille plate 127 to the front plate 121, making disassembly convenient.

[0074] Optionally, the latch 1271 includes a latching arm and a protrusion. One end of the latching arm is connected to the grid plate 127, and the other end of the latching arm has a protrusion protruding towards the inner wall of the mounting hole. When the grid plate 127 is assembled with the front plate 121, the latching arm can undergo elastic deformation so that the protrusion can pass through the mounting hole and extend into the rear side of the front plate 121 to cooperate with the latching slot.

[0075] In this embodiment, the dishwasher also includes a fan, which is installed inside the base 11. The fan can drive the external airflow of the dishwasher into the base 11 to exchange heat with the evaporator 31, and can discharge the low-temperature air after heat exchange to the outside of the dishwasher through the external vent 1211.

[0076] In this embodiment, the dishwasher also includes a water tank assembly and a washing pump, both mounted on the base structure and located below the inner tub. The water tank assembly includes a water tank and a water distribution valve. The water tank communicates with the washing chamber inside the inner tub 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 various 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, where it is heated. The heated washing water then enters the spray mechanism through the water distribution valve for spray cleaning.

[0077] Specifically, the condenser includes a first fluid channel and a second fluid channel. The compressor outlet 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 31, and the outlet of the evaporator 31 is connected to the inlet of the compressor, 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.

[0078] In this embodiment, the condenser includes a heat exchange tube, and a first fluid channel and a second fluid channel are formed inside the heat exchange tube. For example, the heat exchange tube includes an inner tube and an outer tube that are nested together. A first fluid channel is formed between the inner tube and the outer tube, and a second fluid channel is formed inside the inner tube. Alternatively, 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.

[0079] To facilitate drainage, the dishwasher also includes a drain pump housed within the base 11 and 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 extends to the outside of the dishwasher via a pipe.

[0080] It should be noted that the spraying mechanism, water distribution valve, compressor, evaporator 31, condenser, washing pump and drain pump are all existing technologies in the field, and will not be described in detail in this embodiment.

[0081] 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.
