Description

Technical Field

[0001] This invention relates to the field of shoe washing technology, and in particular to a shoe washing machine. Background Technology

[0002] Current fully automatic shoe washing machines generally employ a single structure of brush friction, pure water washing, and low-speed air drying, resulting in a limited washing and care method. High-end air-drying models on the market completely abandon centrifugal structures, relying solely on slow air drying at room temperature using fans. Water has a significant weight and limited penetration capacity, leaving hard-to-clean areas such as shoe linings, tongue layers, and mesh seams. Simple water washing can easily damage shoes, leave detergent residue, result in slow drying, and cause musty odors and mold growth. All shoe washing machines on the market use airflow only for post-drying, never utilizing high-pressure airflow as an active cleaning medium, nor employing a pneumatically driven rotating shaft structure. The industry generally suffers from a polarization, relying either on simple water washing and centrifugal drying or pure air drying; no model achieves a three-in-one architecture combining water and air synergistic cleaning, high-speed centrifugal dehydration, and clean hot air drying.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0025] Please see Figure 1-3This invention provides a technical solution: a shoe washing machine, comprising a body 1 and a washing chamber 2 located within the body 1. The body 1 can be made of various materials, such as metal sheets formed by stamping, welding, or riveting, or high-strength engineering plastics formed by injection molding. The washing chamber 2 is an independent container, and to enhance heat preservation and sound insulation, it adopts a double-layer structure. The washing chamber 2 is equipped with an adaptive locking shoe rack 3, an integrated air-water washing and care mechanism, and a centrifugal dehydration component that drives and cooperates with the adaptive locking shoe rack 3. The upper end of the washing chamber 2 is also equipped with an annular convection air duct mechanism. The adaptive locking shoe rack 3 can be made of metal or high-strength plastic. The structural design allows for the placement and locking of shoes of any size to prevent them from falling off during high-speed rotation. The integrated air-water washing and care mechanism includes multiple nozzles 4, which can be fixed to the side wall of the washing chamber 2. The centrifugal dehydration component is connected to the adaptive locking shoe rack 3 via a transmission mechanism. When in operation, it can drive the shoe rack to rotate at high speed, thereby achieving rapid dehydration of the shoes. The annular convection air duct mechanism consists of multiple air ducts 5, which are arranged in a ring on the top inner wall of the washing chamber 2. The design of the annular convection air duct mechanism aims to guide the airflow to form uniform convection within the washing chamber 2 to improve drying efficiency and uniformity.

[0026] To achieve integrated air-water washing and care, the nozzle 4 includes an air outlet pipe 40 and a water outlet pipe 41. The water outlet pipe 41 is fitted inside the air outlet pipe 40. The air outlet pipe 40 is connected to a high-pressure air pump, and the water outlet pipe 41 is connected to a high-pressure water pump. By connecting the high-pressure air pump to the air outlet pipe 40, the integrated air-water washing and care mechanism is ensured to receive a sufficient and pressurized air source, thereby realizing the functions of blowing, drying, or assisting in cleaning the shoes. At the same time, the high-pressure water pump connected to the water outlet pipe 41 provides a high-pressure water flow to the washing and care mechanism, which can effectively rinse away stains on the shoe surface and improve cleaning efficiency. The structural design of the water outlet pipe 41 being fitted inside the air outlet pipe 40 allows the high-pressure water flow to be enveloped or accompanied by the high-pressure airflow when sprayed, forming an air-water mixed spray. This air-water mixed spray method, on the one hand, utilizes the impact force of the airflow to enhance the removal of stains by the water flow; on the other hand, the introduction of airflow can improve the atomization effect of the water flow, cover a wider area, reduce water droplet splashing, and help accelerate the initial drying of the shoes after washing. This synergy makes the washing and care process more efficient and thorough, and the junction of the air outlet pipe 40 and the water outlet pipe 41 is sealed.

[0027] The adaptive locking shoe rack 3 includes a central support shaft 30, with several shoe hanging positions on the side of the central support shaft 30. Each shoe hanging position includes a pneumatic shoe locking device located on the side of the central support shaft 30 and a corresponding shoe placement plate 31. The shoe placement plate 31 is connected to the side of the central support shaft 30. A limiting plate 32 is provided on the middle surface of the shoe placement plate 31 for slidingly engaging with it to tighten and limit the shoes. A limiting groove is provided in the middle of the shoe placement plate 31, wherein the lower end of the limiting plate 32 is in limiting sliding engagement with the limiting groove. A transmission cylinder is also provided inside the central support shaft 30. The driving end of the transmission cylinder is connected to the limiting plate 32 through a transmission rod to drive the limiting plate 32 to slide along the limiting groove. The shoe placement plate 31 is also hollow to avoid the accumulation of wastewater during the washing process.

[0028] The pneumatic shoe-locking device includes a drive unit located in the central support shaft 30 and a shoe-locking clamp assembly that is driven by the drive unit for locking and limiting the shoe. The shoe-locking clamp assembly includes a connecting rod 33 connected to the drive end of the drive unit. The connecting rod 33 extends from the side of the central support shaft 30 and slides between the central support shaft 30 for limiting. The shoe-locking clamp assembly also includes a clamp 34 hinged to the connecting rod 33. A rotary cylinder is provided between the clamp 34 and the connecting rod 33. The rotary cylinder is used to control the rotation of the clamp 34. In the initial state, there is no angular deflection between the clamp 34 and the connecting rod 33. The drive unit includes, but is not limited to, actuators such as cylinders. When it is necessary to wash the shoes, first place the shoes on the shoe placement plate 31 with the heels close to the central support shaft 30. The rotary cylinder drives the clamp. Rotation 34 causes the clamping plate 34 to extend into the shoe opening. At this time, the driving component drives the connecting rod 33 to retract, thereby causing the clamping plate 34 to move synchronously. Since the heel is close to the central support shaft 30, as the clamping plate 34 moves synchronously with the connecting plate, it will gradually move closer to the central support shaft 30 until the heel is clamped between the clamping plate 34 and the central support shaft 30, thus completing the initial locking of the shoe. When the shoe is placed on the shoe plate 31, the toe is facing the limiting plate 32. Therefore, after the shoe clamping plate assembly initially locks the shoe, the transmission cylinder continues to drive the limiting plate 32 to move closer to the central support shaft 30 until the limiting plate 32 is pressed against the toe, thereby further locking the shoe and ensuring that the shoe will not fall off during high-speed rotation.

[0029] By setting the adaptive locking shoe rack 3, the shoe washing machine can be used for shoes of any size and can lock and limit shoes of any size to ensure that they will not loosen and fall off due to high-speed rotation during the washing process.

[0030] Furthermore, pressure sensors are provided on the side of the clamping plate 34 and the limiting plate 32 facing the shoe. The pressure sensors can sense the clamping force of the clamping plate 34 and the limiting plate 32 on the new shoe, thereby preventing the shoe from being damaged by excessive clamping force or the shoe from being easily loosened due to insufficient clamping force.

[0031] The centrifugal dehydration assembly includes a drive shaft 6 located at the bottom of the cleaning chamber 2. The drive shaft 6 is connected to the central support shaft 30. After cleaning and rinsing, the centrifugal dehydration assembly starts to work. The drive shaft 6 at the bottom of the cleaning chamber 2 drives the entire self-adaptive locking shoe rack 3 and the shoes on it to rotate at high speed through the transmission connection with the central support shaft 30. Due to the centrifugal force, the water inside and on the surface of the shoes is quickly thrown out and discharged through the drainage structure at the bottom of the cleaning chamber 2. This high-speed centrifugal dehydration method can significantly shorten the dehydration time, reduce the water content of the shoes, and prepare for the subsequent drying stage.

[0032] A large amount of wastewater is generated during the washing and dehydration process. If the wastewater cannot be discharged in a timely and effective manner, it may cause water accumulation inside the washing chamber 2, affecting the washing effect and even breeding bacteria, reducing the hygiene performance and service life of the equipment. To address this, this application further proposes that the bottom of the washing chamber 2 is provided with a support base 20, and the support base 20 has a drainage layer inside. The surface of the support base 20 has several through holes 21, which are connected to the drainage layer. The drainage layer has a drain outlet 22 connected to it, and the drain outlet 22 is equipped with a drain valve. By setting the support base 20 at the bottom of the washing chamber 2 and integrating the drainage layer, through holes 21, drain outlet 22 and drain valve inside the base, an efficient wastewater management system is constructed. When the shoe washing machine is washing and centrifugally dehydrating, the water sprayed by the air-water integrated washing and care mechanism and the wastewater generated during washing will collect at the bottom of the washing chamber 2. This wastewater will flow smoothly into the drainage layer inside the support base 20 through the several through holes 21 on the surface of the support base 20. The drainage layer utilizes its internal structural design to guide the collected wastewater to the area of ​​the drain outlet 22. When wastewater needs to be discharged, the wastewater can be discharged from the shoe washing machine by opening the drain valve at drain outlet 22. This structural design allows the wastewater in the cleaning chamber 2 to be collected and discharged in a timely and effective manner, avoiding the accumulation of wastewater in the chamber, thus ensuring the cleanliness and hygiene of the cleaning environment, and providing a good foundation for subsequent dehydration and drying steps, ensuring the smooth and efficient operation of the shoe washing machine as a whole.

[0033] The support base 20 includes a mounting base 23 in the middle, housing a servo motor. A drive shaft 6 is connected to the drive end of the servo motor. A central support shaft 30 is positioned above the mounting base 23. By placing the mounting base 23 in the middle of the support base 20 and integrating the servo motor inside, the drive mechanism is compacted and protected. The servo motor, as a power source, is connected to the drive shaft 6, providing precise and controllable rotational power to the centrifugal dehydration components. This configuration allows for fine adjustment of the rotation speed and acceleration during the dehydration process according to actual needs, thereby optimizing the dehydration effect and reducing potential damage to shoes. Simultaneously, placing the servo motor inside the support base 20 effectively prevents the motor from being directly exposed to the humid environment of the cleaning chamber 2, extending the motor's lifespan and improving the overall reliability of the equipment. The central support shaft 30, positioned above the mounting base 23, ensures stable support and rotation of the self-adaptive locking shoe rack 3, forming a clear functional division with the bottom drive mechanism, resulting in a compact and stable centrifugal dehydration system. This integrated drive system ensures high dehydration efficiency and precision while also enhancing the structural stability and durability of the shoe washing machine. The machine achieves precise, efficient, and controllable drive of the centrifugal dehydration components. The precise speed and torque control provided by the servo motor allows the dehydration process to be optimized based on the shoe's material and humidity, thereby improving dehydration efficiency and reducing damage to the shoes. Simultaneously, integrating the drive mechanism within the support base 20 effectively protects the motor from moisture corrosion, extending the equipment's lifespan and making the overall structure more compact and stable. The central support shaft 30, positioned above the mounting base 23, ensures stable rotation of the shoe rack and good coordination with the drive mechanism, further improving dehydration performance and equipment reliability.

[0034] To reduce noise during equipment operation, a sound insulation layer 24 is provided on the side of the cleaning chamber 2. The sound insulation layer 24 is filled with foamed sound-insulating medium. The air outlet pipe 40 passes through the sound insulation layer 24 and extends out from the side of the cleaning chamber 2. By providing a sound insulation layer 24 on the side of the cleaning chamber 2 and filling it with foamed sound-insulating medium, the aim is to effectively suppress the noise generated during the operation of the shoe washing machine. When the shoe washing machine, especially the integrated air-water washing mechanism, is working, the high-pressure airflow and water jets, as well as the vibration of mechanical parts, generate sound waves. When these sound waves propagate to the side wall of the cleaning chamber 2, they encounter a barrier formed by the sound insulation layer 24 and the foamed sound-insulating medium. The sound insulation layer 24, through its material density and structural characteristics, can reflect and block part of the sound wave propagation; while the foamed sound-insulating medium filled inside the sound insulation layer 24, with its porous structure, causes the sound waves entering it to be reflected and scattered multiple times in the pores, and to rub against the medium material, converting sound energy into heat energy, thereby achieving the absorption and attenuation of sound waves. This combination significantly reduces the transmission of noise to the external environment of the shoe washing machine. Through the above structural configuration, the operating noise of the shoe washing machine can be effectively controlled during washing and care operations, providing users with a quieter and more comfortable operating environment.

[0035] In actual cleaning, due to the varying sizes and shapes of shoes and the relatively fixed positions of the nozzles 4 within the cleaning chamber 2, uneven cleaning coverage may occur, making it difficult to thoroughly clean some areas. Furthermore, the pipes connecting the nozzles 4 may be easily damaged or have their movement restricted due to rigid connections during frequent use or when adjustments are needed. Therefore, each nozzle 4 is equipped with a drive cylinder for transmission. Both the air outlet pipe 40 and the water outlet pipe 41 use corrugated pipes at their ends extending from the side wall of the cleaning chamber 2. Each nozzle 4 corresponds to one shoe hanging position. By configuring an independent nozzle 4 for each shoe hanging position and connecting the nozzle 4 to the drive cylinder, and by using corrugated pipes at the ends of the air outlet pipe 40 and the water outlet pipe 41 extending from the side wall of the cleaning chamber 2, precise control of shoe cleaning and flexibility in pipe connections are achieved. When the shoe washing machine starts the cleaning program, the drive cylinder drives the corresponding nozzle 4 to move or oscillate precisely according to the preset cleaning mode or shoe type. For example, the cylinder can bring the nozzle 4 closer to specific areas such as the shoe upper, sole, or collar, ensuring that the integrated air-water washing and cleaning mechanism can accurately spray high-pressure gas and water to every corner of the shoe. During this process, because the air outlet pipe 40 and water outlet pipe 41 use corrugated pipes, these pipes can freely bend and extend as the nozzle 4 moves, effectively avoiding fatigue damage or loosening of connections caused by frequent pipe movement, ensuring stable delivery of the air-water medium. This design allows each shoe in the hanging position to receive thorough and targeted cleaning, significantly improving the uniformity and thoroughness of the cleaning, and solving the problem of uneven cleaning coverage caused by traditional fixed nozzles 4. Through the above technical solutions, the shoe washing machine can achieve precise and efficient cleaning of shoes. The introduction of the drive cylinder means that the nozzle 4 is no longer fixed but can be dynamically adjusted according to cleaning needs, thus overcoming the limitations of uneven cleaning coverage of traditional fixed nozzles 4 and ensuring that all parts of the shoe are thoroughly cleaned. The use of corrugated pipes effectively solves the problems of wear, breakage, or leakage that may be encountered by the pipes during the movement of the nozzle 4, improving the reliability and service life of the system. In addition, the design of one shoe hanging position for each of the four nozzles not only improves the targeting and efficiency of cleaning, but also significantly enhances the overall cleaning performance and user experience of the shoe washing machine.

[0036] A negative pressure extraction layer is provided between the inner wall of the cleaning chamber 2 and the sound insulation layer 24. This layer has a negative pressure suction port 25 connected to it, and a negative pressure fan connected to the suction port 25. The inner wall of the cleaning chamber 2 also has several air inlets 26 connected to the negative pressure extraction layer. By creating this layer between the inner wall of the cleaning chamber 2 and the sound insulation layer 24, and by continuously extracting air from it using the suction port 25 and the fan, a negative pressure environment is created inside the negative pressure extraction layer. When water mist or moisture generated inside the cleaning chamber 2 attempts to permeate outwards, because the pressure inside the negative pressure extraction layer is lower than the pressure inside the cleaning chamber 2, this moisture and water mist are preferentially drawn into the negative pressure extraction layer and discharged outside the shoe washing machine through the suction port 25 and the fan. This design effectively establishes a moisture barrier between the cleaning chamber 2 and the sound insulation layer 24, preventing moisture from entering the interior of the sound insulation layer 24 and thus protecting the dryness and integrity of the sound insulation medium. This negative pressure dehumidification mechanism, working synergistically with the sound insulation layer 24, not only ensures the shoe washer operates with low noise, but more importantly, it maintains the long-term performance of the sound insulation material, preventing a decrease in sound insulation effect and material damage due to moisture, thereby extending the service life of the shoe washer. Furthermore, by applying negative pressure, a convection channel is formed between the annular convection duct mechanism at the upper end of the cleaning chamber 2 and the negative pressure layer, thereby accelerating the dehydration and drying of the shoes.

[0037] A humidity sensor is also added to the negative pressure air intake 25. By adding the humidity sensor, the humidity in the airflow can be detected, thereby reasonably controlling the working time of the annular convection duct.

[0038] The machine body 1 has a cabin door 10 at its upper end, equipped with safety protection devices including touch-sensitive switches and infrared anti-pinch switches. The cabin door 10 can be made of transparent or semi-transparent impact-resistant material to allow users to observe the internal cleaning process. Specifically, the safety protection devices on the cabin door 10 can be implemented as follows: multiple pressure-sensitive touch-sensitive switches can be embedded in the inner edge of the cabin door 10, i.e., the sealing strip area in contact with the machine body 1. These switches are connected in series or parallel to the control unit of the shoe washing machine. When the cabin door 10 is closing, if an object is present in the door gap, preventing the door from closing completely, the pressure-sensitive resistor will detect the pressure and change its resistance value, thereby triggering a safety signal. Simultaneously, the transmitter and receiver of a through-beam infrared anti-pinch switch can be installed on both sides of the cabin door 10. When the cabin door 10 begins to close, the infrared transmitter continuously emits an infrared beam, and the receiver continuously receives it. If an object (such as a user's hand) blocks the infrared beam, the receiver will not receive the signal and will immediately send an anti-pinch signal to the control unit. Upon receiving any safety signal from a piezoresistive touch switch or a through-beam infrared anti-pinch switch, the control unit will immediately instruct the door drive mechanism to stop closing and may further execute the door to open in the reverse direction to a safe position to ensure user safety.

[0039] The beneficial effects of this invention are as follows: By integrating the adaptive locking shoe rack 3, the air-water integrated washing and care mechanism, the centrifugal dehydration component, and the annular convection air duct mechanism, it achieves water-air coordinated cleaning, high-speed centrifugal dehydration, and efficient drying. It effectively covers complex structural areas such as shoe lining, tongue interlayer, and mesh gaps, avoiding material deformation and delamination caused by prolonged soaking. It has the advantages of increasing the cleaning coverage, shortening the dehydration time, and reducing physical damage. Moreover, the adaptive locking shoe rack 3 can ensure the locking limit of shoes of any size, thereby greatly improving the overall versatility.
