[0064] refer to Figures 1-2 This application proposes a washing device, which includes an inner cavity housing 100, a top cover housing 200, and a drying assembly 500. The top cover housing 200 is disposed above the inner cavity housing 100, and the drying assembly 500 is disposed in the top cover housing 200.

[0065] The top cover housing 200 is provided with a handle 210 for easy handling by the user to detach the top cover housing 200 from the inner housing 100.

[0066] Specifically, the inner cavity housing 100 includes a washing peripheral wall and a washing bottom wall 160, which together form a washing inner cavity with an opening at the top. The top cover housing 200 is installed at the opening at the top of the washing inner cavity to seal the washing inner cavity.

[0067] The bottom of the inner cavity housing 100 is provided with a support base 300. 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.

[0068] The washing equipment involved in this application can be single-layered or double-layered. Single-layered washing equipment refers to a washing inner cavity with only an inner cavity shell 100 single-layer shell structure on the outside.

[0069] A double-layer washing device refers to a double-shell structure formed on the outside of the washing inner cavity. In this application, the inner cavity shell 100 is specifically the inner tank. An outer shell (not shown) is also provided on the outside of the inner cavity shell 100 according to actual usage requirements. An outwardly extending connecting edge is formed on the upper side of the inner cavity shell 100. The inner cavity shell is connected to the outer shell through the connecting edge. The bottom of the outer shell is connected to the support base 300 or integrally formed with the support base 300.

[0070] 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.

[0071] Combination Figure 3 An air duct is formed inside the support upright 110, and a connecting air outlet 111 is formed on the side wall of the support upright 110.

[0072] The drying assembly 500 includes a fan component 510 and an air inlet duct 520. The fan component 510 is disposed in the inner cavity of the top cover, and the air inlet duct 520 is connected and fixed to the top cover housing 200, which is connected to the washing inner cavity.

[0073] 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.

[0074] Specifically, one end of the air inlet duct 520 is fixedly connected to the fan component 510, and the other end extends to the bottom of the top cover housing 200 for communication with the air duct. The dry airflow in the air inlet duct 520 enters the bottom of the washing chamber through the air duct and air outlet 112, and is transported from bottom to top to dry the objects.

[0075] In some embodiments of this application, an air outlet is provided at the upper position of the inner cavity housing 100. After the fan 510 is started, the airflow generated is transported to the washing inner cavity through the air inlet pipe 520 to dry the cleaned baby bottles and other items. The dried airflow is output from the air outlet on the inner cavity housing 100.

[0076] In some other embodiments of this application, the drying assembly 500 further includes a return air duct 530, which is fixed to the top cover housing 200. As the top cover housing 200 moves, an air outlet 230 is provided on the top cover housing 200. One end of the return air duct 530 is connected to the air outlet 230, and the other end is connected to the washing inner cavity.

[0077] The return air duct 530 is equipped with a return air inlet 532, and the airflow in the washing chamber enters the return air duct 530 and is finally output to the outside.

[0078] 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.

[0079] The connecting air vent 111 is provided on the side wall of the support stand 110 and is used to connect with the air inlet duct 520 when the top cover shell 200 is connected. The airflow in the air inlet duct 520 is delivered to the air duct through the connecting air vent 111.

[0080] Specifically, the end of the air inlet duct 520 extending into the washing chamber has an open structure, and the size of the connecting air port 111 is adapted to the open structure of the end of the air inlet duct 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 duct 520, realizing the connection between the air inlet duct 520 and the air duct.

[0081] The drying assembly 500 is installed in the top cover housing 200, located above the inner cavity housing 100. This helps improve safety during the washing and drying process, prevents damage to the fan component 510 caused by leakage of washing water in the washing cavity, and makes it easier for operators to inspect and maintain.

[0082] 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.

[0083] In other embodiments, reference is made to Figure 3 , Figure 4 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.

[0084] 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.

[0085] Alternatively, in other embodiments, refer again to Figure 1 The top cover housing 200 is also provided with multiple air inlets 220 and multiple air outlets 230 on its side wall. 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.

[0086] Refer again Figure 3 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.

[0087] 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.

[0088] 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.

[0089] refer to Figure 2 , Figure 6 , Figure 7 The top cover shell 200 has a top cover cavity, which is a closed chamber structure. In addition to the drying component 500, the top cover cavity also has a drive component 400. Compared with other washing equipment, the main power components of the washing equipment involved in this application are installed in the top cover cavity.

[0090] The top cover housing 200 specifically includes a housing body and a cover plate that can be detachably connected to the equipment body. During installation, after the working parts such as the fan component 510 and the drive component 400 are installed 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.

[0091] 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.

[0092] 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.

[0093] In order to protect the transmission component 440, the support stand 110 is designed as a straight cylindrical structure. The transmission component 440 is specifically a transmission rod, which is installed in the air duct. 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] refer to Figures 9-11 A spray assembly 600 is provided in the washing cavity. The spray assembly 600 includes a filter screen 150, a spray pump housing, and a spray arm 610. The filter screen 150 is horizontally arranged above the washing bottom wall 160. Specifically, a support platform 164 is formed on the washing bottom wall 160, and the filter screen 150 is arranged on the support platform 164. The middle position of the washing bottom wall 160 is recessed downward, and a gap is formed between the filter screen 150 and the middle position of the washing bottom wall 160.

[0101] The spray pump housing is mounted on the filter screen 150, and an inner cavity is formed inside the spray pump housing. The cleaning impeller 450 is installed inside the inner cavity of the pump housing. The 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.

[0102] 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.

[0103] Combination Figure 9 In 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.

[0104] 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.

[0105] refer to Figure 11 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.

[0106] 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.

[0107] For details, please refer to the following: Figure 10 In some embodiments, the spray pump housing includes an upper housing 630 and a lower housing 640, which are detachably connected, and a spray support 631 is formed on the upper housing 630.

[0108] The upper housing 630 and the lower housing 640 are connected by welding to improve the sealing of the connection.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] refer to Figure 2 , Figure 7 as well as Figure 10 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.

[0117] Specifically, in combination Figure 8 A downwardly extending drainage recess 161 is formed on the bottom wall 160 of the washing machine.

An assembly hole adapted to the shape of the assembly end is formed on the connecting part.

[0120] 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.

[0121] 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.

[0122] 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.
