Description

Technical Field

[0001] This invention relates to the field of drum shoe washing machine technology, specifically a dual-drum shoe washing and drying integrated machine. Background Technology

[0002] With the improvement of living standards, people's requirements for personal hygiene and household cleaning equipment are increasing. Shoe washing machines, as a type of household appliance specifically designed for cleaning shoes, are gradually gaining market favor due to their ability to free up hands and improve cleaning efficiency. Existing shoe washing machines are generally divided into single-drum and double-drum structures. Double-drum shoe washing machines, in particular, have become an important direction for technological development because they can separate inner and outer shoes for washing, simultaneously handle shoes of different materials or colors, and improve washing efficiency.

[0003] Currently, the basic structure of dual-drum shoe washing machines on the market includes the machine body, two independent washing drums, a drive system, a water inlet system, a drainage system, and a heating and drying system. To improve the user experience, most mid-to-high-end shoe washing machines integrate a wash-dry function, which uses a heating and drying component to generate hot air to dry the shoes after washing and dehydration.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6 This embodiment of a dual-drum washer-dryer shoe washing machine includes a frame 1, a damper 2 inside the frame 1, a drum shell 3 on the damper 2, a drum 4 inside the drum shell 3, an air inlet 5 and an air return vent 6 symmetrically arranged on the drum shell 3, a counterweight 7 at the bottom of the drum shell 3, a heating element 11 on the drum shell 3, a cover plate 9 fixedly installed on the left side of the frame 1, a door 10 on the cover plate 9, a brushing mechanism 8 inside the door 10 and the drum 4, an ultraviolet lamp 14 embedded in the drum shell 3, a support frame 15 inside the frame 1 and located on the right side of the drum shell 3, a suspension spring 13 fixedly installed on the frame 1 with one end fixedly connected to the drum shell 3, and a filter element 12 on the heating element 11.

[0022] In this embodiment, the filter assembly 12 includes a filter box 121, an air supply pipe 122, an air guide pipe 123, a filter screen 124, a cleaning chamber 125, an L-shaped water collection plate 126, a condenser pipe 127, a drain pipe 128, a condensation mechanism 129, and a cleaning mechanism. The filter box 121 is disposed inside the frame 1 and above the heating assembly 11. The top of the filter box 121 is connected to an air supply pipe 122, one end of which is connected to the heating assembly 11. The bottom of the filter box 121 is connected to an air guide pipe 123, one end of which is connected to the return air vent 6. The interior of the filter box 121 is fixed. A filter screen 124 is installed. A cleaning chamber 125 is embedded at the bottom front of the filter box 121. An L-shaped water collection plate 126 is fixedly installed inside the filter box 121 and above the filter screen 124. A condenser pipe 127 is fixedly installed inside the filter box 121 and above the L-shaped water collection plate 126. A drain pipe 128 is fixedly installed on the front of the filter box 121. The drain pipe 128 passes through the filter box 121 and extends to the L-shaped water collection plate 126. A condensation mechanism 129 is provided on the back of the filter box 121. Cleaning mechanisms are provided on both sides of the filter box 121.

[0023] Specifically, the filter 124 can effectively intercept debris generated during the shoe washing process, preventing debris from entering the heating component 11 and causing corrosion of the heating component 11.

[0024] In this embodiment, the condensation mechanism 129 includes a pump body 1222, a refrigeration box 1223, a semiconductor refrigeration chip 1224, and a connecting pipe 1225. The pump body 1222 and the refrigeration box 1223 are fixedly installed on the back of the filter box 121. The liquid outlet of the pump body 1222 is connected to one end 127 of the condenser tube, and the refrigeration box 1223 is connected to the other end of the condenser tube 127. The liquid inlet of the pump body 1222 is connected to the refrigeration box 1223. The semiconductor refrigeration chip 1224 is embedded on the refrigeration box 1223.

[0025] It should be noted that the hot end of the thermoelectric cooler 1224 is located outside the cooling box 1223, while the cold end of the thermoelectric cooler 1224 is in contact with the coolant inside the cooling box 1223.

[0026] Specifically, turning on the semiconductor cooling chip 1224 cools the coolant, and starting the pump 1222 delivers the cooler coolant to the condenser tube 127. The hot and humid air generated during drying comes into contact with the cooler condenser tube 127, producing condensate that adheres to the outer wall of the condenser tube 127. The condensate drips onto the L-shaped water collection plate 126 and is discharged through the drain pipe 128. The air, now free of moisture, returns to the heating assembly 11 through the air supply pipe 122, thus performing a rapid drying operation for the shoes.

[0027] In this embodiment, the cleaning mechanism includes a cleaning box 1216, a cleaning plate 1218, a slide rail 1210, a lifting plate 1211, a motor 1212, a threaded rod 1213, a threaded slider 1214, and a pusher block 1215. The slide rail 1210 is fixedly installed on both the front and back sides of the filter box 121. The lifting plate 1211 is slidably installed on the slide rail 1210.

A threaded slider 1214 is fitted onto the external thread of the threaded rod 1213. The opposite side of the threaded slider 1214 is fixedly connected to the cleaning box 1216. The cleaning plate 1218 is slidably installed on the cleaning box 1216, and the cleaning plate 1218 abuts against the filter screen 124. A pusher block 1215 is fixedly installed on the top of the threaded slider 1214.

[0028] Specifically, the motors 1212 on both sides are started simultaneously, rotating the threaded rod 1213. The threaded rod 1213 drives the threaded slider 1214 to move the filter box 121 horizontally. The cleaning plate 1218 on the filter box 121 scrapes off the impurities attached to the filter screen 124, thus achieving the purpose of automatically cleaning the filter screen 124.

[0029] In this embodiment, the cleaning box 1216 has a receiving cavity 1217, the cleaning plate 1218 is slidably installed in the receiving cavity 1217, a telescopic spring 1219 with one end fixedly connected to the cleaning plate 1218 is fixedly installed inside the receiving cavity 1217, and the cleaning box 1216 has a cleaning door 1220.

[0030] Specifically, the extension spring 1219 ensures that the cleaning plate 1218 remains in contact with the filter screen 124; opening the cleaning door 1220 allows for the removal of impurities collected in the cleaning box 1216.

[0031] In this embodiment, the side of the lifting plate 1211 that contacts the pushing block 1215 is set as an arc surface.

[0032] Specifically, the curved surface design ensures that the lifting plate 1211 will not cause obstruction when the push block 1215 moves left and right.

[0033] In this embodiment, the heating assembly 11 includes a heating shell, a heating wire, a fan, and a nozzle. The heating wire and the fan are arranged sequentially from left to right inside the heating shell. The nozzle is connected to the left side of the heating shell and is connected to the air inlet pipe 5. The air inlet of the drum fan is connected to the air supply pipe 122.

[0034] Specifically, the heating element is turned on, and the fan is started to deliver hot air to the air nozzle. The hot air is then blown into the drum of shoes that have been washed, through the air inlet pipe 5, to quickly dry the shoes.

[0035] In this embodiment, a sealing block 1221 is fixedly installed at the bottom of the filter screen 124, and the sealing block 1221 is in contact with the cleaning box 1216.

[0036] Specifically, the sealing block 1221 is designed to ensure that impurities do not enter the cleaning box 1216 when adsorbing impurities, and the sealing block 1221 has bevels on both sides, which does not affect the movement of the lifting plate 1211.

[0037] In this embodiment, the brushing mechanism 8 includes a door brush 81, a wall brush 82, and a bottom brush 83.

[0038] Specifically, the door brush 81, wall brush 82, and bottom brush 83 can thoroughly clean the shoes without any blind spots, achieving the goal of washing without any dead angles. In addition, the wall brush 82 is designed with a wave shape that is high in the middle and high on both sides, which is based on the contour of the shoes and can reduce damage to the shoes during washing.

[0039] The working principle of the above embodiments is as follows: (1) Put the shoes that need to be cleaned into the roller 4, start the machine, and under the action of the brush mechanism 8, the shoes will be rolled and brushed.

[0040] (2) After the shoes are washed, turn on the heating wire and start the fan to deliver hot air to the air nozzle. The hot air is then blown into the drum of the shoes through the air inlet pipe 5 to perform a quick drying operation. (3) The filter screen 124 can effectively intercept the debris generated during the shoe washing process, preventing the debris from entering the heating component 11 and causing corrosion of the heating component 11; (4) Simultaneously start the motors 1212 on both sides to rotate the threaded rod 1213. The threaded rod 1213 drives the threaded slider 1214 to move the filter box 121 horizontally. The cleaning plate 1218 on the filter box 121 scrapes off the impurities attached to the filter screen 124, thus achieving the purpose of automatically cleaning the filter screen 124.
