Description

Technical Field

[0001] This utility model belongs to the technical field of shoe washing machine, and relates to a softening device for a shoe washing machine, especially a rapid steam softening device for a shoe washing machine. Background Technology

[0002] Shoes made of textiles and fabrics, such as sneakers and athletic shoes, are difficult to clean after getting stained, and it is time-consuming and laborious. With the popularization of automated home appliances, shoe washing machines have gradually been launched and updated, entering the field of vision of young people. Young people are starting to choose shoe washing machines to replace manual cleaning of shoes.

[0003] Existing shoe washing machine technologies mainly include converted brush-type washing machines, ultrasonic shoe washing machines, and high-pressure spray shoe washing machines. Among these, converted brush-type washing machines have long washing times, cause significant wear and tear on the shoe surface due to the brushes, and are prone to cross-contamination of bacteria due to inadequate disinfection. Ultrasonic shoe washing machines are highly dependent on the shoe's shape, material, and detergent. They often fail to thoroughly clean complex-shaped shoes or stubborn stains in small crevices. Furthermore, some materials are less sensitive to ultrasonic waves and are difficult to clean. High-pressure spray shoe washing machines rely on high-pressure fine water jets to rinse the shoe surface. This non-contact cleaning method reduces the risk of cross-contamination; however, it cannot effectively soften stubborn stains and its cleaning effect on the inside of the shoe is generally limited. Utility Model Content

[0004] The purpose of this invention is to provide a rapid steam softening device for shoe washing machines, in order to solve the technical problems in the prior art that are greatly affected by shoe fabric, are prone to cross-contamination, and cannot effectively soften stubborn stains on the shoe surface, resulting in poor cleaning effect.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A rapid steam softening device for a shoe washing machine includes a main housing, a cleaning inner tank and a control unit mounted on the main housing, and a water inlet unit, a pumping unit, a steam generation and delivery unit, and a temperature control unit, all electrically connected to the control unit. One end of the water inlet unit is connected to an external water source via a pipeline, and the other end is connected to the steam generation and delivery unit via a pipeline through the pumping unit. Multiple steam nozzles are evenly arranged on the side wall of the cleaning inner tank, and a water outlet pipe extending from the main housing is provided at the bottom of the cleaning inner tank. The steam outlet of the steam generation and delivery unit is connected to the multiple steam nozzles via a high-temperature, high-pressure explosion-proof pipe. The temperature control unit is electrically connected to the steam generation and delivery unit and communicatively connected to the control unit.

[0007] The water inlet unit includes a water inlet pipe and a solenoid valve. The water inlet of the water inlet pipe extends out of the main housing and connects to an external water source. The solenoid valve is mounted on the water inlet pipe and is electrically connected to the control unit.

[0008] The pumping unit includes an electromagnetic pulse pump electrically connected to the control unit. The two ends of the electromagnetic pulse pump are respectively connected to the outlet of the electromagnetic valve and the inlet of the steam generation and delivery unit through pipelines.

[0009] The steam generation and delivery unit includes a steam furnace and a steam distributor. The steam furnace is electrically connected to the control unit. The steam outlet of the steam furnace is connected to the steam inlet of the steam distributor through a high-temperature and high-pressure explosion-proof main pipe. Each steam outlet of the steam distributor is connected to multiple steam nozzles through a high-temperature and high-pressure explosion-proof branch pipe.

[0010] The temperature control unit includes a temperature controller and a temperature probe. The temperature controller is disposed on the outer surface of the steam furnace, connected in series with the heating tube of the steam furnace, and electrically connected to the control unit.

[0011] The temperature probe is located on the side wall of the upper part of the cleaning inner tank and is electrically and communicatively connected to the control unit.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a rapid steam softening device for a shoe washing machine. By setting up a steam generation and delivery unit, the inhaled water is rapidly heated to generate high-temperature, high-pressure steam. This high-temperature steam is then distributed and rapidly sprayed into the inner cavity of the cleaning tank through high-temperature, high-pressure explosion-proof pipes and steam nozzles, enabling a steam bath within the tank. The control unit uses feedback signals from a temperature probe to control the water inlet speed of the solenoid valve and the duty cycle of the steam furnace heating pipe using a thermostat, maintaining the steam bath temperature within the cleaning tank at a constant 55°C. This softens stains and allows them to quickly blend with the washing liquid, thus assisting the shoe washing machine in effectively removing stubborn stains from shoes.

[0013] The technical solution provided by this utility model can precisely adjust the water intake, generate steam quickly and efficiently, control the temperature accurately and with a small temperature gradient, achieve high mixing efficiency with detergent, and has strong cleaning power. It is suitable for cleaning textile and fabric shoes such as travel shoes and sports shoes that are difficult to clean, and is suitable for widespread application in shoe washing machines.

[0018] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, this utility model provides a rapid steam softening device for a shoe washing machine, which includes a main housing 1, a cleaning inner tank 2 and a control unit 3 disposed on the main housing 1, and a water inlet unit, a pumping unit, a steam generation and delivery unit, and a temperature control unit, all electrically connected to the control unit 3. One end of the water inlet unit is connected to an external water source via a pipeline, and the other end is connected to the steam generation and delivery unit via a pipeline through the pumping unit, for supplying water to the steam generation and delivery unit.

[0020] In order to provide the shoes with uniform high-temperature steam, in this embodiment, multiple steam nozzles 4 are evenly arranged on the side wall and bottom surface of the cleaning inner liner 2. A water outlet pipe extending out of the main shell 1 is arranged in the middle of the bottom of the cleaning inner liner 2. The arrangement of the steam nozzles 4 makes the steam inner liner a steam bath for cleaning shoes. The shoes are placed upside down in the cleaning inner liner 2. The bottom steam nozzles 4 are used to spray high-temperature steam into the inside of the upside-down shoes to clean and soften the stains inside the shoes. The side steam nozzles 4 are used to spray high-temperature steam onto the sides of the shoes to clean and soften the stains on the outer surface of the shoes.

[0021] The steam outlet of the steam generation and delivery unit is connected to multiple steam nozzles 4 via high-temperature, high-pressure, explosion-proof pipes. These nozzles heat and vaporize the liquid water supplied by the water inlet unit into high-temperature steam, which is then ejected at high speed from the steam nozzles 4 through the high-temperature, high-pressure, explosion-proof pipes, providing a high-temperature, humid environment for cleaning the interior of the inner tank 2. The temperature control unit is electrically connected to the steam generation and delivery unit and communicatively connected to the control unit 3. It controls the duty cycle of the heating element in the steam delivery unit, regulates heating, and works in conjunction with the control unit 3 to prevent the steam generation and delivery unit from dry-burning.

[0022] Furthermore, in this embodiment, the water inlet unit includes a water inlet pipe 5 and a solenoid valve 6. The inlet of the water inlet pipe 5 extends out of the main housing 1 and connects to an external water source. The solenoid valve 6 is mounted on the water inlet pipe 5 and electrically connected to the control unit 3. The pumping unit includes an electromagnetic pulse pump 7 electrically connected to the control unit 3. The two ends of the electromagnetic pulse pump 7 are respectively connected to the outlet of the solenoid valve 6 and the inlet of the steam generation and delivery unit through pipelines. The solenoid valve 6 and the electromagnetic pulse pump 7 are used to regulate the water intake of the steam generation and delivery unit, which, in conjunction with the high-power heating element of the steam generation and delivery unit, rapidly generates steam.

[0023] Furthermore, the steam generation and delivery unit in this embodiment includes a steam furnace 8 and a steam distributor 9. The steam furnace 8 is electrically connected to the control unit 3. The water inlet of the steam furnace 8 is connected to the electromagnetic pulse pump 7 via a pipeline. The steam outlet is connected to the steam inlet of the steam distributor 9 via a high-temperature and high-pressure explosion-proof main pipe 10. Each steam outlet of the steam distributor 9 is connected to multiple steam nozzles 4 via a high-temperature and high-pressure explosion-proof branch pipe 11.

[0024] To facilitate monitoring the steam temperature inside the inner tank 2 and to allow the control unit 3 to comprehensively regulate the water inlet rate and heating element duty cycle of the steam furnace 8, the temperature control unit in this embodiment includes a temperature controller 12 and a temperature probe 13. The temperature probe 13 is mounted on the upper side wall of the inner tank 2, electrically and communicatively connected to the control unit 3, and is used to monitor the steam temperature inside the inner tank 2 and feed the temperature signal back to the control unit 3. The temperature controller 12 is electrically connected to the control unit 3, mounted on the outer surface of the steam furnace 8, and connected in series with the heating element of the steam furnace 8. The control unit 3 controls the temperature controller 12 to adjust the heating power of the steam furnace 8 based on the feedback signal from the temperature probe 13, and simultaneously adjusts the water supply rate of the solenoid valve 6.

[0025] The working principle of the technical solution provided in this embodiment is as follows:

[0026] Control unit 3 uses solenoid valve 6 to control the water supply and electromagnetic pulse pump 7 to regulate the water flow into steam furnace 8. This allows the water entering steam furnace 8 to rapidly form high-temperature steam under the influence of the high-power heating element. The expanding steam, generating pressure, flows through high-temperature, high-pressure explosion-proof main pipe 10 into steam distributor 9. After being split by steam distributor 9, the steam is rapidly sprayed from the steam nozzles 4 on the bottom and sides of the cleaning inner tank 2 through high-temperature, high-pressure explosion-proof branch pipes 11. This fills the cavity inside the cleaning inner tank 2 with high-temperature steam, thus providing a steam bath for the shoes inside. Temperature probe 13 inside the cleaning inner tank 2 monitors the steam temperature in real time. Control unit 3 adjusts the heating power of electromagnetic pulse pump 7 and steam generator based on the feedback data from temperature probe 13, maintaining the steam bath temperature inside the cleaning inner tank 2 at approximately 55℃. This temperature effectively promotes the rapid softening of stains and their integration with detergent, enhancing the stain removal effect of the shoe washing machine.
