[0039] A multi-stage air-drying device for a box washing machine, see [link / reference] Figures 1 to 13 It includes at least one air-drying device 1 and one drying device 2 connected to the main body 6 of the washing machine. The main body 6 of the washing machine is located at the front end of the air-drying device 1 and the air-drying device 1 is located at the front end of the drying device 2. The number of air-drying devices 1 and drying devices 2 can be selected according to the user's needs. For example, it can be a sequential combination of one air-drying device 1 and one drying device 2, or a sequential combination of two air-drying devices 1 and one drying device 2, etc.

[0040] A transmission device 3 is installed at the bottom of the air-drying device 1 and the drying device 2. The transmission device 3 continuously conveys turnover boxes or baking trays to the air-drying device 1 and the drying device 2. The transmission device 3 is a chain drive mechanism and the turnover boxes or baking trays are fixed by the clamping column 31 and the height-adjustable pressure rod 32.

[0041] The air drying device 1 includes: a housing 11 and a fan 12 disposed on the top of the housing 11. The housing 11 has an inlet 111, an outlet 112, and a channel 113 communicating with the inlet 111 and the outlet 112. The air outlet 121 of the fan 12 is connected to the channel 113. In the air drying device 1, the air inlet 122 of the fan 12 is connected to the channel 113 so that a loop is formed between the channel 113 and the fan 12, and the air is circulated for air drying.

[0042] The drying device 2 includes a housing 21 and a fan 22 disposed on the top of the housing 21. The housing 21 has an inlet 211, an outlet 212, and a channel 213 communicating with the inlet 211 and the outlet 212. The air outlet 221 of the fan 22 is connected to the channel 213. In the drying device 2, the air inlet 222 of the fan 22 is connected to a heating element 23, which is connected to the channel 213, so that a loop is formed between the channel 213, the fan 22, and the heating element 23. By setting the connection relationship between the channel 213, the fan 22, and the heating element 23, and by using the method of connecting the heating element 23 to the air inlet 222 of the fan 22, a loop is formed between the channel 213, the fan 22, and the heating element 23, which reduces heat loss and saves energy.

[0043] The system employs a multi-stage air-drying and drying method. First, it uses a heatless air-drying method to dry most of the water stains on the turnover box. Then, it uses a combination of drying and air-drying to thoroughly solve the problem of water stains on the turnover box after cleaning, effectively ensuring the dryness of the turnover box and meeting the user's needs.

[0044] In this embodiment, in order to prevent heat dissipation, multiple flexible baffles 4 are connected to the inlets 111 and 211 and the outlets 112 and 212 respectively to form a curtain for shielding 111, 211 and the outlets 112 and 212. By connecting multiple baffles 4 to 111, 211 and the outlets 112 and 212 respectively to form a curtain for shielding 111, 211 and the outlets 112 and 212, heat dissipation of the circuit is prevented, and energy consumption is further saved.

[0045] In this embodiment, an air duct assembly 13 is provided in the channel 113. The air duct assembly 13 is the prior art. The air duct assembly 13 has an air inlet 131 and an air outlet 132. The air inlet 131 is connected to the air outlet end 121 of the fan 12. The air outlet 132 faces the corners and surfaces of the turnover box or baking tray conveyed by the transmission device 3 through the channel 113. An air duct assembly 24 is provided in the channel 213. The air duct assembly 24 has an air inlet 241 and an air outlet 242. The air inlet 241 is connected to the air outlet end 221 of the fan 22. The air outlet 242 faces the corners and surfaces of the turnover box or baking tray conveyed by the transmission device 3 through the channel 213.

[0046] Furthermore, in the drying device 2, the air duct assembly 24 includes an air duct housing 243, which forms a container channel 244 through its front and rear sides. The air duct housing 243 is provided with an air inlet chamber 245 and an air outlet chamber 246 communicating with the air inlet chamber 245. An air inlet 241 is provided on the air duct housing 243 corresponding to the air inlet chamber 245, and an air outlet 242 is provided on the air duct housing 243 corresponding to the air outlet chamber 246 and faces the container channel 244. On the air duct housing 243, a guide plate 247 is connected to the air outlet 242.

[0047] Furthermore, the air outlet chamber 246 has an upper air outlet chamber 2461, a lower air outlet chamber 2462, and side air outlet chambers 2643 and 2644 that are respectively connected to the left and right sides of the upper air outlet chamber 2461 and the lower air outlet chamber 2462. The upper air outlet chamber 2461, the lower air outlet chamber 2462, and the side air outlet chambers 2463 and 2464 surround the container channel 244. The air outlets 242 are respectively set on the air duct housings 243 corresponding to the upper air outlet chamber 2461, the lower air outlet chamber 2462, and the side air outlet chambers 2463 and 2464, and face the container channel 244. By setting a separate air duct assembly 24, the air outlet of the fan 22 is dispersed. The air outlets 242 set on the upper, lower, left, and right sides of the air outlet chamber 246 ensure the uniformity and stability of the air outlet, resulting in a better drying effect.

[0048] Furthermore, the number of air outlets 242 in the upper air outlet cavity 2461 is less than the number of air outlets 242 in the side air outlet cavities 2463 and 2464, the number of air outlets 242 in the side air outlet cavities 2463 and 2464 is less than the number of air outlets 242 in the lower air outlet cavity 2462, and the size of the air outlets 242 in the upper air outlet cavity 2461 is smaller than the size of the air outlets 242 in the side air outlet cavities 2463 and 2464. The air outlet 242 of air chambers 2463 and 2464 is smaller than the air outlet 242 of the lower air outlet 2462. Because the air outlet 242 of the upper air outlet 2461 is closer to the air inlet 245, followed by the air outlets 242 of the side air outlets 2463 and 2464, and finally the air outlet 424 of the lower air outlet 2462, the airflow at the air outlet 242 of the upper air outlet 2461 is stronger than that at the side air outlet 2462. The air outlets 242 of 463 and 2464 are next in importance, and the air outlet 242 of the lower air outlet 2462 is last. By setting the number of air outlets 242 of the upper air outlet 2461 less than the number of air outlets 242 of the side air outlets 2463 and 2464, and the number of air outlets 242 of the side air outlets 2463 and 2464 less than the number of air outlets 242 of the lower air outlet 2462, the uniformity of airflow from the upper, lower, left, and right air outlets is ensured, resulting in good airflow performance. Furthermore, by setting the size of the air outlet 242 of the upper air outlet 2461 to be slightly smaller, the air outlets 242 of the side air outlets 2463 and 2464 to be next in importance, and the air outlet 242 of the lower air outlet 2462 to be last, the uniformity and stability of airflow from each air outlet are further ensured, resulting in good air-drying performance.

[0049] In this embodiment, the heating unit 23 includes a housing 231 with a heat exchange cavity 2311. The heat exchange cavity 2311 is connected to the channel 213.

The heat exchange tube assembly 232 has a heat medium inlet 2321 and a heat medium outlet 2322, so that heat medium is introduced through the heat medium inlet 2321 and discharged from the heat medium outlet 2322. The heat medium is hot steam, which heats the air entering the heat exchange cavity 2311. By introducing heat medium into the heat exchange tube assembly 232 through the heat medium inlet 2321 and discharging it from the heat medium outlet 2322, the air entering the heat exchange cavity 2311 is heated, thus solving the safety hazard problem and ensuring safety and reliability.

[0050] Furthermore, the heat exchange tube assembly 232 includes at least one heat exchange tube group 2323. The number of heat exchange tube groups 2323 is selected according to the dryness and wetness requirements of the container. The heat exchange tube group 2323 is slidably and detachably connected to the shell 231. Specifically, an installation port 2312 is opened in the shell 231, and a sealing plate 2313 is connected to the installation port 2312.
