[0061] refer to Figures 1-4 This application proposes a washing device, which includes an inner cavity housing 100, a support base 300, a top cover housing 200, a drive assembly 400, and a drain impeller 460.

[0062] The support base 300 is located below the inner cavity housing 100, and the top cover housing 200 is located above the inner cavity housing 100. The power mechanism on the drive assembly 400 is installed in the top cover housing 200 above the inner cavity housing 100.

[0063] 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.

[0064] Specifically, a downwardly extending drainage recess 161 is formed on the bottom wall 160 of the washing machine, and a drainage impeller 460 is connected in the drainage recess 161. The drainage recess 161 is located in the middle of the bottom wall 160 of the washing machine, and a drainage interface 162 is provided on the side wall of the drainage recess 161, and a drainage pipe is connected to the outside of the drainage interface 162.

[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] A shelf 140 is horizontally installed at the bottom of the washing chamber, which is used to support baby bottles waiting to be cleaned.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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 components 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.

[0074] The drive assembly 400 provides power for the washing and / or draining process of the washing equipment. The drive assembly 400 includes a drive member 410 and a transmission member 440, and a drain impeller 460 is connected to the bottom of the transmission member 440.

[0075] The driving component 410 is specifically a drive motor, which is installed in the inner cavity of the top cover. The driving component 410 is arranged vertically in the inner cavity of the top cover, and the output end of the driving component 410 extends downward to the outer side of the top cover shell and is detachably connected to the transmission component 440 installed in the washing inner cavity.

[0076] For details, please refer to the following: Figure 2 , Figure 4as well as Figure 7 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 drainage impeller 460. When the top cover shell 200 is connected to the inner cavity shell 100, the first docking part 420 is connected to the second docking part 430 so that the drive component 410 drives the drainage impeller 460 to rotate.

[0077] 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.

[0078] 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.

[0079] Since the drive unit 410 involved in the washing equipment is a low-power drive motor, which is relatively light in weight, 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.

[0080] 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.

[0081] The outer side of the support stand 110 is also provided with multiple hanging ears for hanging the receiving and cleaning items.

[0082] 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.

[0083] When the top cover shell 200 is connected to the inner cavity shell 100 from top to bottom, each mating protrusion on the first mating part 420 is inserted into the corresponding mating recess, thereby realizing the connection between the first mating part 420 and the second mating part 430.

[0084] refer to Figure 2 , Figure 4 as well as Figure 8 In other embodiments, a drain impeller 460 is connected to the end of the transmission member 440 for draining water from the washing chamber after washing is completed.

[0085] The drainage recess 161 is located directly below the transmission member 440, and the drainage impeller 460 is located inside the drainage recess 161.

[0086] The direction of the drain interface 162 is consistent with the tangent direction of the drain recess 161, and the whole has 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.

[0087] refer to Figure 5 The bottom of the transmission component 440 has an assembly end, and an assembly cut surface 441 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 461 adapted to the shape of the assembly end is formed on the connecting part.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] In some embodiments of this application, the bottom of the transmission member 440 is connected to a cleaning impeller 450, which is located above the drain impeller 460 and is used to provide power for spraying the washing water of the washing equipment.

[0095] refer to Figures 9-10 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.

[0096] 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 into the washing cavity.

[0097] 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.

[0098] 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.

[0099] For details, please refer to the following: Figure 8 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.

[0100] The upper housing 630 and the lower housing 640 are connected by welding to improve the sealing of the connection.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] The spray support 631 is integrally formed with the upper housing 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.

[0108] The water intake of this washing equipment is from top to bottom. A water pump 500 is also installed in the inner cavity of the top cover. The water pump 500 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.

[0109] During washing, the water inlet pump 500 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.

[0110] Combination Figure 6In other embodiments, in order to improve the cleaning effect, the present application also provides a water heating element 310 in the mounting cavity of the support base 300, and a bottom mounting port 163 is provided on the washing bottom wall 160. The water heating element 310 extends into the washing cavity through the bottom mounting port 163 for heating the washing water.

[0111] In other embodiments, reference again Figure 5 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.

[0112] refer to Figure 6 The installation cavity is also equipped with a drain valve 320, which is connected to the drain pipe to prevent wastewater from flowing back into the drain pipe. A solenoid valve 321 is also connected to the drain valve 320 to control the opening and closing size and opening and closing time of the drain valve 320, thereby improving the safety of the opening and closing of the drain valve 320.

[0113] refer to Figures 7-14 In 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 230 is provided on the lower surface of the top cover shell. The control part is connected to the first signal part 230. 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 310 and the drain valve 320.
