[0002] With the continuous advancement of technology and the continuous improvement of people's living standards, household cleaning equipment has gradually become an essential appliance, especially for families with mothers and babies. Baby bottles are an essential baby product for these families, and it is necessary to clean narrow-mouthed bottles, cups, and other irregularly shaped items such as nipples.

[0003] Existing cleaning equipment typically houses the water pump and drying components within a base at the bottom of the washing chamber. This poses a risk of water leakage within the washing chamber, potentially affecting the operation of the components. Furthermore, the components housed within the base are inconvenient to maintain and costly to repair. To address these issues, a design is proposed that mount the cleaning drive unit and drying components within a top cover housing, which is positioned above the inner chamber housing. However, since the top cover housing contains the drive unit and drying components, vibrations may occur during operation. Simply placing the top cover housing over the inner chamber housing could lead to displacement of the top cover housing, causing issues with the connection of the drive unit and the proper functioning of the drying component.

[0090] Specifically, the movable locking tongue 730 is used to engage with the lower part of the locking part 130 to achieve the connection between the top cover housing 200 and the inner cavity housing 100.

[0091] In some embodiments of this application, combined with Figure 18 The top cover shell 200 is racetrack shaped, and the washing peripheral wall includes a straight section 101 and an arc section 102. The movable locking tongue 730 is provided on the arc section 102.

[0092] refer to Figures 3-5 The linkage assembly 720 includes a rotating rod 721, an active linkage 722, a linear linkage 723, and a driven linkage 724. The rotating rod 721 is rotatably connected in the rotating hole 280 of the top cover housing 200 along the vertical direction.

[0093] The rotating rod 721 includes a first end and a second end. The first end of the rotating rod 721, which extends to the upper surface of the top cover housing 200, is connected to the operating part 710. The second end of the rotating rod 721, which extends to the lower surface of the top cover housing 200, is connected to one end of the active connecting rod 722 through an eccentric protrusion 7212.

The straight connecting rod 723 is movably connected to the lower surface of the top cover housing 200 along the direction of approaching or away from the center of the arc segment 102 through a guide assembly.

[0094] Combination Figure 6 A connecting surface 7211 is formed on the outer wall of the first end of the rotating rod 721. A connecting sleeve is formed at the bottom of the operating part 710. The inner wall of the connecting sleeve is adapted to the first end of the rotating rod 721 to achieve synchronous rotation of the operating part 710 and the rotating rod 721. An operating handle is provided on the top of the operating part 710 for convenient hand operation by the user.

[0095] refer to Figure 18 The guide assembly includes a guide recess 7231 formed on the straight connecting rod 723 and a guide protrusion 270 formed on the lower surface of the top cover housing 200, wherein the guide recess 7231 and the guide protrusion 270 are connected in a mating manner.

[0096] Alternatively, the guide assembly may include a guide protrusion 270 formed on the straight link and a guide recess 7231 formed on the lower surface of the top cover housing 200.

[0097] The straight connecting rod 723 is symmetrically provided with driven connecting rods 724 on both sides. The other end of each driven connecting rod 724 is connected to the movable locking tongue 730. The movable locking tongue 730 is arc-shaped, and the other end of the movable locking tongue 730 is rotatably connected to the lower surface of the top cover shell 200.

[0098] A downwardly protruding rotating shaft 290 is provided at a corresponding position on the lower surface of the top cover housing 200, and the other end of the movable locking tongue 730 is rotatably connected to the rotating shaft 290.

[0099] Combination Figure 7 On the outer side of each movable latch 730 (that is, on the side away from the center of the arc segment 102 along the horizontal direction), a plurality of snap-fit ​​protrusions 731 are provided at intervals. A movable limiting part 260 is formed on the lower surface of the top cover housing 200. A limiting hole 261 is formed in the movable limiting part 260 along the horizontal direction. As the movable latch 730 moves, the snap-fit ​​protrusions 731 can be moved and connected to the corresponding limiting hole 261.

[0100] Specifically, in the locked state, the engaging protrusion 731 extends from the limiting hole 261 to the outside of the movable limiting part 260 and engages with the lower side of the corresponding locking part 130.

[0101] In the unlocked state, the snap-fit ​​protrusion 731 retracts into the limiting hole 261 and separates from the locking part 130.

[0102] The locking and unlocking process of the locking device 700 is described in detail below:

[0103] Combination Figure 16 After the item to be cleaned is placed into the washing chamber, the user places the top cover 200 on the inner chamber housing 100. The racetrack-shaped structure of the top cover 200 and the inner chamber housing 100 facilitates positioning.

[0104] After the top cover housing 200 moves down into place, the user operates the operating part 710 located above the top cover housing 200. Under the action of the linkage assembly 720, combined with... Figure 20 The movable locking tongue 730 rotates at an angle about the rotation shaft 290 on the lower surface of the top cover housing 200 along the direction close to the movable limiting part 260 until the locking protrusion 731 is engaged in the limiting hole 261.

[0105] When it is necessary to open the top cover housing 200, the user rotates the operating part 710 in the opposite direction, and the movable locking tongue part 730 rotates at an angle about the rotation shaft 290 in the direction away from the movable limiting part 260, so that the locking protrusion 731 disengages from the limiting hole 261.

[0106] In some embodiments of this application, in order to match the path of the snap-fit ​​protrusion 731 moving into or out of the limiting hole 261 and to avoid interference between the snap-fit ​​protrusion 731 and the side wall of the limiting hole 261, this application designs that each snap-fit ​​protrusion 731 has a transition arc surface on the side near the driven connecting rod 724, so that the snap-fit ​​protrusion 731 can smoothly move into or out of the limiting hole 261.

[0107] In other embodiments, the guide protrusion 270 is provided with a limiting end 271 at one end away from the outer wall of the top cover housing 200, for limiting the maximum displacement of the straight connecting rod 723 in the direction of moving closer to the center of the arc segment 102.

[0108] To facilitate user installation and removal of the top cover housing 200, in some embodiments of this application, a handle portion 210 is provided on the top cover housing 200, an operating recess is formed between the handle portion 210 and the top cover housing 200, and an operating portion 710 is disposed in the operating recess.

[0109] The operating recess is specifically located on the inner side of the handle 210 near the center of the arc segment 102, that is, the two operating recesses are arranged opposite each other.

[0110] The operation units 710 are respectively provided in the operation recesses and are used to control the movable locking tongue 730 on the corresponding side.

[0111] The operating part 710 includes a locked state and a disengaged state. In the locked state, the operating part 710 is retracted into the operating recess and contacts the side wall of the operating recess, and the movable locking tongue 730 engages with the locking part 130. In the disengaged state, the operating part 710 rotates to the outside of the operating recess until the operating part 710 rotates until the straight connecting rod 723 contacts the limiting end 271, and the movable locking tongue 730 separates from the locking part 130.

[0112] Of course, the specific relative positions of the operating part 710 and the operating recess can be determined based on the initial installation position of the operating part 710 and can be changed according to the user's actual operating habits.

[0113] refer to Figure 8 In order to protect the locking device 700, this application also provides a sealing plate 740 on the lower surface of the top cover housing 200, and the sealing plate 740 covers the outside of the connecting rod assembly 720.

[0114] The sealing plate 740 is equipped with fasteners such as fastening screws, which are fixed to the lower surface of the top cover housing 200 to prevent the locking device 700 from being affected by washing water.

[0115] The top cover shell 200 is connected to the inner cavity shell 100 via a locking device 700. The user controls the position of the movable locking part 730 through the operating part, thereby connecting or separating it from the locking part 130 on the washing inner cavity to fix the position of the top cover shell 200. During the operation of the washing equipment, the vibration generated by the drive component 410, the drying component 500, etc., will not affect the connection state between the top cover shell 200 and the inner cavity shell 100, which helps to improve the stability of the connection and avoids the abnormal operation of the drive component 410 and the drying component 500 due to misalignment caused by vibration.

[0116] refer to Figure 11 A shelf 140 is horizontally installed at the bottom of the washing chamber to support baby bottles waiting to be cleaned.

[0117] A support stand 110 is vertically arranged in the washing cavity. One end of the support stand 110 is connected to the bottom of the washing cavity, and the other end extends upward to the upper part of the washing cavity.

[0118] The support base 300 is located at the bottom of the inner cavity housing 100. The support base 300 is a housing structure with an opening at the top. An installation cavity is formed between the support base 300 and the washing bottom wall 160 of the inner cavity housing 100.

[0119] The top cover housing 200 has a top cover inner cavity, which is a closed chamber structure. The drive assembly 400 is partially installed in the top cover inner cavity. Compared with other washing equipment, the main power components of the washing equipment involved in this application are installed in the top cover inner cavity.

[0120] The top cover housing 200 specifically includes a housing body and a cover plate that is detachably connected to the equipment body. During installation, after the power components and other parts are fixed in the inner cavity of the top cover, the cover plate is placed on top of the housing body to seal the inner cavity of the top cover.

[0121] refer to Figure 2 , Figure 9 , Figure 10 The drive assembly 400 provides power for the washing and / or drainage process of the washing equipment. The drive assembly 400 includes a drive member 410 and a transmission member 440. The drive member 410 is specifically a drive motor, which is disposed in the inner cavity of the top cover. The drive member 410 is arranged vertically in the inner cavity of the top cover. The output end of the drive member 410 extends downward to the outer side of the top cover shell and is detachably connected to the transmission member 440 disposed in the washing inner cavity.

[0122] The transmission component 440 is rotatably connected to the support stand 110. The output end of the drive component 410 is provided with a first docking part 420, the upper end of the transmission component 440 is provided with a second docking part 430, and the lower end of the transmission component 440 is connected to a cleaning impeller 450 and / or a drainage impeller 460. When the top cover housing 200 is connected to the inner cavity housing 100, the first docking part 420 is connected to the second docking part 430 so that the drive component 410 drives the cleaning impeller 450 and / or the drainage impeller 460 to rotate.

[0123] In order to protect the transmission component 440, the support stand 110 is designed as a straight cylindrical structure with a through support cavity inside. The transmission component 440 is specifically a transmission rod, which is disposed in the support cavity. The upper part of the transmission rod extends to the upper part of the support stand 110, and the second docking part 430 is located above the support stand 110.

[0124] Before washing, the top cover shell 200 is removed from the inner cavity shell 100. During removal, the first docking part 420 and the second docking part 430 are separated. Then, the baby bottle waiting to be cleaned is placed in the washing inner cavity. Finally, the top cover shell 200 is fixed to the inner cavity shell 100, and the first docking part 420 and the second docking part 430 are reconnected. The drive member 410 drives the transmission member 440 to rotate, which in turn drives the washing impeller 450 and / or the drain impeller 460 below to rotate, so as to achieve the purpose of washing or draining.

[0125] Since the drive unit 410 involved in the washing equipment is a low-power drive motor, it is relatively light in weight. Therefore, the process of disassembling and assembling the top cover shell 200 from the inner cavity shell 100 will not place a great burden on the operator.

[0126] Alternatively, in some other embodiments, a door may be provided on the side wall of the inner cavity housing 100 to facilitate the user in taking and placing items to be cleaned.

[0127] The first docking part 420 and the second docking part 430 are detachably connected by mechanical coupling. Specifically, the first docking part 420 has multiple docking protrusions distributed around its periphery, and the second docking part 430 has an upward-opening docking cavity. The side wall of the docking cavity has multiple vertically arranged docking recesses, and the docking protrusions and docking recesses correspond one-to-one.

[0128] When the top cover shell 200 is connected to the inner cavity shell 100 from top to bottom, each docking protrusion on the first docking part 420 is inserted into the corresponding docking recess, thereby realizing the connection between the first docking part 420 and the second docking part 430.

[0129] In some embodiments of this application, the bottom of the transmission member 440 is connected to a cleaning impeller 450, which provides power for spraying washing water from the washing equipment.

[0130] refer to Figure 13 , Figure 14 A spray assembly 600 is provided in the washing cavity. The spray assembly 600 includes a spray pump housing and a spray arm 610. The spray pump housing is specifically connected to the bottom wall 160 of the washing machine. An inner cavity is formed inside the spray pump housing. A cleaning impeller 450 is installed in the inner cavity of the pump housing. A transmission member 440 extends from the top of the spray pump housing into the inner cavity of the pump housing. The cleaning impeller 450 is fixed on the transmission member 440. As the transmission member 440 rotates, the cleaning impeller 450 rotates accordingly.

[0131] A spray support 631 is provided above the spray pump housing, and a spray arm 610 is rotatably connected to the spray support 631. Spray holes are provided on the spray wall for outputting washing water to the washing inner cavity.

[0132] refer to Figure 15 The pump casing cavity includes a water collection section 601 and water passages 602 arranged around the water collection area. The cleaning impeller 450 is arranged inside the water collection section 601. Each water passage 602 extends outward along the tangent direction of the water collection section 601, forming a circular involute structure with the water collection section 601. The spray support section 631 is arranged at the end of the water passage 602.

[0133] The inner cavity of the pump casing is formed inside the spray pump casing, and the overall shape of the spray pump casing is adapted to the inner cavity of the pump casing.

[0134] For details, please refer to the following: Figure 14 The spray pump housing includes an upper housing 630 and a lower housing 640, which are detachably connected. A spray support 631 is formed on the upper housing 630.

[0135] The upper housing 630 and the lower housing 640 are connected by welding to improve the sealing of the connection.

[0136] The pump casing cavity is connected to the washing cavity, and the lower housing 640 is provided with an opening to allow the washing water in the washing cavity to enter the pump casing cavity.

[0137] In some other embodiments, a filter element 150 is also provided between the spray pump housing and the spray arm 610. The filter element 150 has filter holes (not shown) to filter residue and prevent clogging of the drain pipe.

[0138] A support platform 164 is provided at a lower position in the washing cavity. The support platform 164 is specifically an annular protrusion on the side wall of the washing cavity, and the filter screen 150 is connected to the support platform 164 on its periphery.

[0139] In some embodiments, two water passages 602 are provided around the water collection section 601. The two water passages 602 are symmetrically arranged on both sides of the water collection section 601, and the two water passages 602 extend in the same direction on the water collection section 601. The offset direction of each water passage 602 relative to the water collection section 601 is consistent with the rotation direction of the cleaning impeller 450, so that when the cleaning impeller 450 rotates, the water flow is guided into each water passage 602, and finally sprayed out from the spray arm 610 into the washing cavity.

[0140] Each water passage 602 is connected to a spray arm 610 at its end. The spray arm 610 is rotatably connected to the spray support 631 so that when the washing water is sprayed out from the spray arm 610, the spray arm 610 rotates relative to the spray support 631 under the reaction of the water flow, thereby improving the uniformity of washing.

[0141] The spray arm 610 is also equipped with an upwardly extending spray column 620. The top of the spray column 620 is equipped with a water outlet. The upper part of the spray column 620 is used to support small-diameter items such as baby bottles to be cleaned. The washing water output from the water outlet on the spray column 620 can be directly delivered to the inner cavity of the baby bottle to be cleaned, so as to achieve the purpose of cleaning the inner cavity.

[0142] The spray support 631 is integrally formed with the upper shell 630. The spray support 631 is a through cylindrical structure. Water passage holes are formed on the side wall of the spray support 631. Water in the water passage 602 is transported to the spray arm 610 through the spray support 631.

[0143] refer to Figure 10 as well as Figure 12 In some other embodiments, the end of the transmission member 440 is connected to a drain impeller 460 for draining water from the washing chamber after washing is completed.

[0144] Specifically, a downwardly extending drain recess 161 is formed on the bottom wall 160 of the washing machine. The drain recess 161 is located in the middle of the bottom wall 160 of the washing machine. A drain interface 162 is provided on the side wall of the drain recess 161, and a drain pipe is connected to the drain interface 162.

[0145] The direction of the drain interface 162 is consistent with the tangent direction of the drain recess 161. The drain interface 162 and the drain recess 161 form a circular involute structure. When the cleaning impeller 450 and the drain impeller 460 are connected to the transmission component 440 at the same time, the tangent direction of the drain interface 162 on the drain recess 161 is opposite to the deflection direction of the water passage 602 relative to the water collection part 601.

[0146] The bottom of the transmission component 440 has an assembly end, and an assembly cut surface is formed on the outer wall of the assembly end. The drainage impeller 460 includes a connecting part and drainage blades formed around the connecting part. An assembly hole adapted to the shape of the assembly end is formed on the connecting part.

[0147] During the cleaning process, both the cleaning impeller 450 and the drainage impeller 460 rotate along the first direction. At this time, the water in the water collection part 601 enters the water passage 602. When the drainage impeller 460 rotates along the first direction, the water flow direction is opposite to the opening direction of the drainage interface 162, and no drainage is performed.

[0148] During the drainage process, both the cleaning impeller 450 and the drainage impeller 460 rotate in the second direction. At this time, the water flow direction in the water collection part 601 is opposite to the opening direction of the water passage 602, and no water enters the water passage 602. The water flow direction in the drainage recess 161 is opposite to the opening direction of the drainage interface 162. The water in the drainage recess 161 enters the drainage pipe through the drainage interface 162 under the action of the drainage impeller 460.

[0149] In other words, the drainage recess 161 is located directly below the transmission member 440, and the drainage impeller 460 is located at the bottom of the transmission member 440. The drainage impeller 460 is rotatably connected in the drainage recess 161 and is used to discharge washing water from the drain pipe.

[0150] The drain pipe extends along the tangent of the drain recess 161, and the extension direction of the drain pipe is opposite to the extension direction of each water passage.

[0151] During washing, the transmission component 440 drives the washing impeller and the drain impeller 460 to rotate in the first direction, and the washing water in the water collection part 601 enters the water passage part under the action of the washing impeller.

[0152] During drainage, the transmission component 440 drives the washing impeller and the drainage impeller 460 to rotate in a second direction opposite to the first direction, and the water in the drainage recess 161 enters the drainage pipe under the action of the drainage impeller 460.

[0153] The water inlet of this washing equipment is from top to bottom. A water inlet pump 800 is also installed in the inner cavity of the top cover. The water inlet pump 800 is connected to a water supply pipe and a water inlet pipe. The water supply pipe is used to connect to an external water source, and the water inlet pipe is connected to the inner cavity of the washing equipment.

[0154] During washing, the water inlet pump 800 is turned on, and the washing water input through the water supply pipe is transported from the water inlet pipe to the washing inner cavity. Under the action of the cleaning impeller 450, the washing water enters the water passage 602 and is sprayed out from the spray arm 610.

[0155] In other embodiments, in order to improve the cleaning effect, a water heating element is also provided in the mounting cavity of the support base 300, and a bottom mounting port 163 is provided on the bottom wall 160. The water heating element extends into the washing cavity through the bottom mounting port 163 for heating the washing water.

[0156] refer to Figure 2 , Figures 16-18 In some embodiments of this application, the washing equipment is further provided with a drying component 500 for drying the washed baby bottles and the like.

[0157] The drying assembly 500 includes a fan component 510, an air inlet duct 520, and a return air duct 530. The fan component 510 is disposed in the inner cavity of the top cover. The air inlet duct 520 and the return air duct 530 are connected and fixed to the top cover housing 200, which is connected to the washing inner cavity.

[0158] A through-flow air duct is formed inside the support upright 110. One end of the air inlet pipe 520 is fixedly connected to the fan component 510, and the other end extends to the bottom of the top cover shell 200 for communication with the air duct. One end of the return air pipe 530 is connected to the washing inner cavity through the return air port 532, and the other end is connected to the outside.

[0159] The top cover housing 200 is provided with an air inlet 220 and an air outlet 230. The air inlet 220 is used to connect the inner cavity of the top cover with the outside world, so that the airflow from the outside can enter the inner cavity of the top cover and be transported to the air duct through the fan component 510 and the air inlet pipe 520.

[0160] The other end of the return air duct 530 is fixedly connected to the air outlet 230 on the top cover housing, and is used to output the airflow from the washing chamber to the outside.

[0161] Specifically, in combination Figure 11 The support stand 110 has a connecting air port 111 on its side wall. The end of the air inlet pipe 520 that extends into the washing cavity is an open structure. The size of the connecting air port 111 is adapted to the end opening structure of the air inlet pipe 520. After the top cover shell is installed on the washing shell, the connecting air port 111 is connected to the end of the air inlet pipe 520, realizing the connection between the air inlet pipe 520 and the air duct.

[0162] To improve the accuracy of the connection, a positioning area is formed between the ends of the air inlet duct 520 and the return air duct 530 that extend into the washing cavity. The support stand 110 is located in the positioning area. The cross-sectional shape of the support stand 110 along the horizontal direction is rectangular. The ends of the air inlet duct 520 and the end of the return air duct 530 are located on both sides of the support stand 110.

[0163] In other embodiments, reference is made to... Figure 17 The end of the return air duct 530 is provided with a sealing end 531, and the return air inlet 532 on the return air duct 530 faces the top cover housing 200. That is, the return air inlet 532 is located above the return air duct 530 to prevent washing water from entering during the washing process.

[0164] refer to Figure 16 To prevent foreign objects from entering the inner cavity of the top cover or the air outlet duct from the air inlet 220 and the air outlet 230, air outlet grilles are also provided on the air inlet 220 and the air outlet 230 of the top cover shell 200.

[0165] Alternatively, in some other embodiments, the side wall of the top cover housing 200 is provided with a plurality of air inlets 220 and a plurality of air outlets 230. The air inlets 220 and air outlets 230 are arranged in an array on the top cover housing 200 to reduce the size of a single air inlet 220 and air outlet 230 while ensuring the air intake and air output, so as to prevent foreign objects from entering.

[0166] An air vent 112 is provided on the side wall of the support stand 110. The air vent 112 is located at the lower part of the support stand 110. The airflow in the air duct is delivered to the washing inner cavity through the air vent 112 provided at the bottom of the support stand 110, so that the drying airflow dries the cleaned baby bottles from bottom to top, ensuring that the inner cavity of the baby bottles waiting to be cleaned is dry.

[0167] Combined again Figure 13In some embodiments, in order to facilitate the fixing of the bottom of the support stand 110, the support stand 110 is fixed to the spray pump housing at the bottom of the washing cavity. Specifically, an upwardly extending fixing part 632 is formed on the spray pump housing. The fixing part 632 is also a sleeve structure. The fixing part 632 is adapted to the size of the support stand 110. The support stand 110 is detachably connected to the fixing part 632.

[0168] The fixing part 632 is provided with a plurality of through mating holes 633 on its periphery. The mating holes 633 correspond one-to-one with the air outlets 112. During the drying process, under the action of the fan 510, the drying airflow passes through the air duct and is output from the mating holes 633 and the air outlets 112 to the washing cavity.

[0169] In order to further increase the capacity of the washing cavity and facilitate the fixing of bottle caps, handles, etc., this application provides a plurality of hanging ears 113 on the outer wall of the support stand 110. Bottle caps, handles, etc. can be directly hung on the hanging ears 113, thereby improving the cleaning effect and increasing the bottle capacity.

[0170] In other embodiments, reference again Figure 11 The shelf 140 is also provided with a support frame 141. The support frame 141 is located on the side of the shelf 140, close to the inner wall of the washing cavity. The support frame 141 includes a support upright beam 1411 and a support crossbeam 1412. The bottom wall of the support upright beam is connected to the shelf 140. A support arc surface is formed on the support crossbeam to support the items to be cleaned, improve the cleaning effect, and avoid the items to be cleaned from stacking together and forming cleaning dead corners.

[0171] refer to Figure 17 In some embodiments of this application, the air inlet duct 520 includes an inclined section that is angled to the support stand 110, and a vertically arranged one-way valve 522 is provided in the inclined section for controlling the one-way delivery of the drying airflow in the air inlet duct 520 to the washing inner cavity.

[0172] The one-way valve 522 is specifically a baffle structure that is vertically installed in the inclined section. The top of the baffle is hinged to the top wall of the inclined section so that the baffle can only be opened in one direction towards the opening of the air inlet pipe.

[0173] An airflow heating element 521 is also provided in the air inlet duct 520 to heat the dry airflow passing through the air inlet duct 520.

[0174] A drain valve is also installed inside the cavity, which is connected to the drain pipe to prevent wastewater from flowing back into the drain pipe.

[0175] refer to Figure 19 , Figure 20In addition to the mechanical coupling between the first mating part 420 and the second mating part 430, the top cover shell 200 and the inner cavity shell 100 also have signal coupling. A control part is formed on the top cover shell 200, and a first signal part 250 is provided on the lower surface of the top cover shell. The control part is connected to the first signal part 250. A second signal part 120 is installed on the inner cavity shell 100. The second signal part 120 is connected to the water heating element and the drain valve. When the top cover shell 200 is installed on the inner cavity shell 100, the first signal part 250 is connected to the second signal part 120. The control part is configured to control the switching of the water heating element and the drain valve.

[0176] Specifically, a female connector is formed at the lower end of the first signal section 250, and a male connector is formed at the upper end of the second signal section 120. When the top cover housing 200 is installed on the inner cavity housing 100, the male connector is inserted into the female connector to realize the connection between the first signal section 250 and the second signal section 120.

[0177] Specifically, the second signal unit 120 is fixed to the inner cavity housing 100 by a mounting bracket 121. The mounting bracket 121 is located on the outside of the inner cavity housing 100, and the bottom of the mounting bracket 121 extends into the inner cavity.

[0178] refer to Figure 21 A vertically extending wiring recess 170 is formed on the outer wall of the inner cavity housing 100. The wiring recess 170 extends toward the washing inner cavity. A wiring cavity is formed between the mounting bracket 121 and the wiring recess 170. The wiring harness connecting the second signal unit 120 and the water heating element and drain valve is arranged in the wiring cavity. That is, the wiring harness extends from top to bottom through the wiring cavity to the mounting cavity and connects with the water heating element, drain valve, etc.

[0179] The top cover housing 200 is also provided with a power supply connector 240, which is connected to a power supply harness. The power supply harness is connected to the drive component 410 and the fan component 510 respectively. In addition, a power supply plug can also be provided in the first signal section 250 inside the top cover cavity, which is connected to the power supply socket in the second signal section 120.
