Description

Technical Field

[0001] This application relates to the field of cabinet technology, specifically to a multi-layer shoe cabinet with directional air supply at the shoe opening and air extraction at the shoe toe. Background Technology

[0002] Currently, shoe cabinets and shoe drying equipment are widely used in homes, dormitories, and other places, mainly for storing, dehumidifying, drying, deodorizing, and sterilizing shoes to improve their comfort and hygiene. Existing technologies primarily achieve these functions by integrating heating elements, ventilation fans, and disinfection modules. Specifically, heating elements are usually installed at the bottom, back, or sides of the cabinet, increasing the internal temperature through heat conduction and radiation to accelerate moisture evaporation; ventilation systems are mostly located at the top or back of the cabinet, using fans to exchange air inside and outside the cabinet, with some high-end devices combining heating to create hot air circulation; sterilization and deodorization often employ ultraviolet lamps or photocatalytic modules, using ultraviolet light to destroy the structure of microorganisms or catalytically decompose odor molecules.

[0003] However, existing technologies still have the following shortcomings: Poor airflow directionality and low drying efficiency: Existing ventilation methods are mostly non-directional diffusion, making it difficult for airflow to effectively penetrate the shoe surface and enter the shoe cavity, resulting in uneven humidity distribution inside the shoe, incomplete dehumidification, long processing time, and high energy consumption.

[0004] Photocatalytic treatment poses safety and environmental risks: existing methods directly irradiate the shoe surface with light, which can easily cause aging and damage to the shoe materials; at the same time, the ozone and organic intermediates generated during the photocatalytic process lack collection and purification treatment, which can easily diffuse into the indoor environment, causing secondary pollution and posing health risks.

[0005] Lack of negative pressure closed-loop control and unreasonable airflow path: The existing system does not have a differential pressure feedback mechanism, which cannot maintain a stable negative pressure environment in the shoe cavity, resulting in unstable airflow dynamics. This may damage the shoe surface due to excessive negative pressure or affect the drying effect due to insufficient negative pressure. In addition, the airflow path is mostly limited to the space inside the cabinet and does not achieve directional flow, resulting in low airflow utilization efficiency.

[0006] In summary, existing technologies have significant shortcomings in airflow organization, purification, and system control, and there is an urgent need for a shoe cabinet system that can achieve directional airflow, efficient purification, and closed-loop control. Summary of the Invention

[0007] To achieve directional airflow, efficient purification, and closed-loop control in a shoe cabinet, in a first aspect, embodiments of this application provide a multi-layer shoe cabinet with directional airflow at the shoe opening and extraction at the shoe toe, comprising a cabinet body, wherein the cabinet body is provided with: A multi-layer shoe rack, which enters a tilting mode after the automatic door of the shoe cabinet is closed; The fan, heater, and distribution chamber are located at the bottom of the cabinet. The air drawn in by the fan is heated by the heater and then enters the distribution chamber. The slit-type air outlets are provided on each layer of the shoe rack. The slit-type air outlets are connected to the distribution cavity, and their air outlet direction is set towards the shoe openings of the shoes placed on the shoe rack. An air extraction head is installed at the corresponding shoe toe position on each layer of the shoe rack; A sealed exhaust channel is connected to each exhaust head, and an exhaust fan is installed downstream of the sealed exhaust channel. When the exhaust fan is running, a negative pressure zone is formed at the exhaust head. A detachable photocatalytic device and a detachable exhaust gas treatment device are connected in series in the sealed exhaust channel; A tail gas detector is installed at the outlet of the sealed exhaust channel; A circulating air channel connecting the exhaust gas detector outlet and the distribution chamber, wherein a circulating air inlet and a circulating air outlet are respectively provided at both ends of the circulating air channel; Control center; The negative pressure zone formed during the operation of the exhaust fan induces the airflow from the slit-type air outlet to enter the shoe cavity through the shoe opening and flow directionally to the toe position. After being drawn out by the air extraction head, it enters the sealed exhaust channel. The extracted air flows through the photocatalytic device and the exhaust gas treatment device in sequence for purification treatment before reaching the exhaust gas detector. The exhaust gas detector sends a detection signal to the control center. When the detection result reaches a preset specific value, the control center controls the gas to enter the circulating gas channel through the circulating gas inlet and return to the distribution chamber through the circulating gas outlet to achieve recycling. When the detection result does not reach the preset specific value, the control center controls the gas to be discharged outside the cabinet under the action of the exhaust fan.

[0008] In one possible implementation, the shoe rack has an inclination angle of 15° to 30°, and the air outlet of the slit-type air outlet is tilted upward relative to the horizontal plane by 15° to 30°.

[0009] In one possible implementation, the preset specific values ​​include: a volatile organic compound (VOC) concentration of 300-600 ppb, an ozone (O3) concentration of 50-80 ppb, and a relative humidity (RH) of 45-55%.

[0010] In one possible implementation, the control center is configured to: open the recirculation inlet to allow gas to flow back to the distribution chamber when the detection result of the exhaust gas detector reaches a preset specific value; and close the recirculation inlet and allow gas to be discharged from the cabinet when the detection result does not reach the preset specific value.

[0011] In one possible implementation, the sealed exhaust channel is physically isolated from the shoe cavity space to prevent cross-contamination of gases between different layers of the shoe cavity.

[0012] In one possible implementation, when the exhaust fan is running, the negative pressure zone formed at the toe of the shoe works together with the airflow delivered from the slit-type air outlet to form a unidirectional directional airflow from the shoe opening to the toe.

[0013] In one possible implementation, the shoe rack has a support structure at the rear to prevent the shoes from slipping off when the rack is tilted.

[0014] In one possible implementation, the control center is also used to adjust the air volume of the exhaust fan based on the detection signal from the exhaust gas detector.

[0015] Secondly, embodiments of this application provide a method for directional air supply to the shoe opening and extraction to the shoe toe of a shoe cabinet, applicable to the first aspect of shoe cabinets, including: The negative pressure zone created by the exhaust fan induces the airflow from the slit-type air outlet to enter the shoe cavity through the shoe opening and flow directionally to the toe area. After being drawn through the extraction head, the air enters a closed exhaust channel; the extracted air flows through the photocatalytic device and the exhaust gas treatment device for purification before reaching the exhaust gas detector. The exhaust gas detector sends a detection signal to the control center. When the detection result reaches a preset specific value, the control center controls the gas to enter the circulating gas channel through the circulating air inlet and return to the distribution chamber through the circulating air outlet to achieve recycling. When the detection result does not reach the preset specific value, the control center controls the gas to be discharged outside the cabinet under the action of the exhaust fan.

[0016] Thirdly, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the above-described method for directional air supply at the shoe opening and air extraction at the shoe toe.

[0017] This application provides a multi-layer shoe cabinet with directional air supply at the shoe opening and suction at the shoe toe. The cabinet includes: a multi-layer shoe rack, which tilts after the automatic door closes; a fan, heater, and distribution chamber located at the bottom of the cabinet, where air drawn in by the fan is heated by the heater and then enters the distribution chamber; a slit-type air outlet on each shoe rack, connected to the distribution chamber, with its airflow direction directed towards the shoe opening of the shoes placed on the rack; a suction head at the corresponding shoe toe position on each shoe rack; a sealed exhaust channel connected to each suction head, with an exhaust fan downstream of the sealed exhaust channel, creating a negative pressure zone at the suction head during operation; a detachable photocatalytic device and a detachable exhaust gas treatment device connected in series within the sealed exhaust channel; and exhaust gas treatment at the outlet of the sealed exhaust channel. The system includes: a detector; a circulating air channel connecting the outlet of the exhaust gas detector to the distribution chamber, with a circulating air inlet and a circulating air outlet at each end; a control center; wherein, the negative pressure zone formed by the exhaust fan induces the airflow from the slit-type air outlet to enter the shoe cavity through the shoe opening and flow directionally to the toe position, where it is extracted by the extraction head and enters the sealed exhaust channel; the extracted air flows sequentially through the photocatalytic device and the exhaust gas treatment device for purification before reaching the exhaust gas detector; the exhaust gas detector sends a detection signal to the control center; when the detection result reaches a preset specific value, the control center controls the gas to enter the circulating air channel through the circulating air inlet and return to the distribution chamber through the circulating air outlet for recycling; when the detection result does not reach the preset specific value, the control center controls the gas to be discharged outside the cabinet under the action of the exhaust fan. The shoe cabinet of this application achieves directional air supply, high-efficiency purification, and closed-loop control. Attached Figure Description

Detailed Implementation

[0019] The present invention will be described in detail below through embodiments.

[0020] Currently, shoe cabinets and shoe drying equipment are widely used in homes, dormitories, and other places, mainly for storing, dehumidifying, drying, deodorizing, and sterilizing shoes to improve their comfort and hygiene. Existing technologies primarily achieve these functions by integrating heating elements, ventilation fans, and disinfection modules. Specifically, heating elements are usually installed at the bottom, back, or sides of the cabinet, increasing the internal temperature through heat conduction and radiation to accelerate moisture evaporation; ventilation systems are mostly located at the top or back of the cabinet, using fans to exchange air inside and outside the cabinet, with some high-end devices combining heating to create hot air circulation; sterilization and deodorization often employ ultraviolet lamps or photocatalytic modules, using ultraviolet light to destroy the structure of microorganisms or catalytically decompose odor molecules.

[0021] However, existing technologies still have the following shortcomings: Poor airflow directionality and low drying efficiency: Existing ventilation methods are mostly non-directional diffusion, making it difficult for airflow to effectively penetrate the shoe surface and enter the shoe cavity, resulting in uneven humidity distribution inside the shoe, incomplete dehumidification, long processing time, and high energy consumption.

[0022] Photocatalytic treatment poses safety and environmental risks: existing methods directly irradiate the shoe surface with light, which can easily cause aging and damage to the shoe materials; at the same time, the ozone and organic intermediates generated during the photocatalytic process lack collection and purification treatment, which can easily diffuse into the indoor environment, causing secondary pollution and posing health risks.

[0023] Lack of negative pressure closed-loop control and unreasonable airflow path: The existing system does not have a differential pressure feedback mechanism, which cannot maintain a stable negative pressure environment in the shoe cavity, resulting in unstable airflow dynamics. This may damage the shoe surface due to excessive negative pressure or affect the drying effect due to insufficient negative pressure. In addition, the airflow path is mostly limited to the space inside the cabinet and does not achieve directional flow, resulting in low airflow utilization efficiency.

[0024] In summary, existing technologies have significant shortcomings in airflow organization, purification, and system control, and there is an urgent need for a shoe cabinet system that can achieve directional airflow, efficient purification, and closed-loop control.

[0025] Firstly, see [the following] Figure 1 This application provides a multi-layer shoe cabinet with directional air supply at the shoe opening and air extraction at the shoe toe, including a cabinet body, wherein the cabinet body is provided with: The multi-layer shoe rack 17 enters a tilting mode after the automatic door 15 of the shoe cabinet is closed.

[0026] The shoe rack 17 has a support structure at the rear to prevent the shoes from slipping off when the rack is tilted.

[0027] The fan 01, heater 02 and distribution chamber 03 are installed at the bottom of the cabinet. The air drawn in by the fan 01 is heated by the heater 02 and then enters the distribution chamber 03.

[0028] The slit-type air outlet 04 is provided on each layer of the shoe rack. The slit-type air outlet is connected to the distribution cavity 03, and its air outlet direction is set towards the shoe opening of the shoe placed on the shoe rack.

[0029] The shoe rack 17 has an inclination angle of 15° to 30°, and the air outlet 04 has an air outlet direction that is tilted upward relative to the horizontal plane by 15° to 30°.

[0030] After the airflow comes out of the distribution chamber, it is guided by the air outlet channel wall and sprayed out along the channel direction.

[0031] The advantage of this design is that it creates a reverse airflow, increasing the uniformity of drying: airflow enters from the lower part of the shoe opening and must overcome gravity to diffuse upwards to reach the higher part of the shoe toe. This reverse path allows hot air to stay inside the shoe cavity longer and circulate fully, preventing the airflow from directly short-circuiting from the shoe opening to the exhaust vent, ensuring that the deep parts of the shoe, such as the toe, are also dried evenly. Furthermore, with the toe pointing upwards and the shoe opening downwards, air intake and ventilation are easier. If there is residual sweat or condensation inside the shoe, it will naturally flow to the lower part of the shoe opening and be quickly carried away by the airflow or dripped off, preventing water from accumulating at the toe. If not tilted (e.g., laid flat), moisture tends to accumulate at the lowest point of the shoe toe, leading to localized dampness. At an angle less than 15°, airflow resistance is low but short-circuiting is easy, and the water-wicking effect is not significant; at an angle greater than 30°, although the exhaust at the toe is more thorough, the heavy heel may cause the shoe to slip backwards, or slippers and other low-cut shoes may easily fall off. 15°-30° is a safe range for balancing ventilation and slip prevention.

[0032] An air extraction head 11 is installed at the corresponding shoe toe position on each layer of the shoe rack.

[0033] Because the toe is slightly raised, the vent can fit more closely to the toe area, making it easier to seal and connect.

[0034] A sealed exhaust channel 14 is connected to each exhaust head 11. An exhaust fan 06 is provided downstream of the sealed exhaust channel 14. When the exhaust fan 06 is running, a negative pressure zone is formed at the exhaust head 11.

[0035] The shoe cabinet provided in this embodiment has an air extraction opening (i.e., an air extraction head 11) at the shoe toe. Multiple air extraction openings are connected to a sealed exhaust channel. An exhaust fan is provided downstream of the exhaust channel to create negative pressure and achieve simultaneous air extraction from each shoe toe.

[0036] The sealed exhaust channel 14 is physically isolated from the shoe cavity 05 to prevent cross-contamination of gases between different layers of the shoe cavity.

[0037] When the exhaust fan 06 is running, the negative pressure zone formed at the toe of the shoe and the airflow delivered by the slit-type air outlet 04 work together to form a unidirectional airflow from the shoe opening to the toe.

[0038] Airflow enters through the shoe opening and penetrates the shoe cavity, transporting moisture and volatile pollutants inside the shoe to the toe area, creating a true penetrating wind that runs through the entire shoe.

[0039] A detachable photocatalytic device 13 and a detachable exhaust gas treatment device 12 are connected in series in the sealed exhaust channel 14.

[0040] The extracted gas from inside the shoe enters a sealed exhaust channel isolated from the shoe cavity. The channel is equipped with a photocatalytic purification unit and an exhaust gas treatment unit. Before leaving the channel, the exhaust or reused gas must be filtered, adsorbed, and disinfected by the photocatalytic purification unit and the exhaust gas treatment unit to ensure the cleanliness and safety of the gas and prevent cross-contamination between shoe cavities.

[0041] The exhaust gas detector 10 is installed at the outlet of the sealed exhaust channel 14.

[0042] A circulating air channel 08 is connected to the outlet of the exhaust gas detector 10 and the distribution chamber 03. The two ends of the circulating air channel 08 are respectively provided with a circulating air inlet 07 and a circulating air outlet 09.

[0043] Control Center 16.

[0044] The negative pressure zone formed by the exhaust fan 06 during operation induces the airflow sent from the slit-type air outlet 04 to enter the shoe cavity 05 through the shoe opening and flow in a direction to the toe position. After being drawn out by the air extraction head 11, it enters the sealed exhaust channel 14. The extracted air flows through the photocatalytic device 13 and the exhaust gas treatment device 12 in sequence for purification treatment before reaching the exhaust gas detector 10.

[0045] See Figure 2 This diagram illustrates the airflow into the shoe cavity in this application. The induction process utilizes fluid dynamics principles such as pressure difference and wall adhesion to change the direction of airflow, passively drawing it into a specific area. Airflow, obliquely directed upwards from a slit-type outlet, is drawn into the shoe cavity by the induction effect of the low-pressure area near the shoe opening. The shoe opening acts as a natural guide lip, thus creating a directional airflow from the shoe opening to the toe. This process involves no forced deflection of the airflow; it relies on the synergistic effect of the airflow direction and pressure gradient.

[0046] This application creates a true airflow through the shoe rather than just air supplied and exhausted within the cavity. The bottom distribution cavity and directional air supply through slits, combined with air extraction at the toe, form an airflow path from the shoe opening through the shoe cavity to the toe, significantly improving the air renewal rate and dehumidification speed inside the shoe. Existing technologies often use cavity ventilation, which can easily cause airflow to short-circuit within the cavity and make it difficult to eliminate localized damp spots. This application, through its directional air supply and toe extraction airflow design, ensures that the airflow must pass through the inside of the shoe cavity, thereby improving drying and dehumidification efficiency and shortening processing time. Furthermore, this application's embodiments ensure that the gas must pass through a closed processing link in the shoe's air purification system. This system requires the extracted air from inside the shoe to pass through a closed photocatalytic reaction section and exhaust gas treatment unit before being discharged or reused, preventing photocatalytic byproducts (such as ozone or partially oxidized intermediates) from directly leaking into the room, thus improving the system's safety and reliability. Unlike solutions that place the light source or coating directly in the shoe cavity, this application completes purification and series exhaust gas treatment in an independent gas phase channel, significantly reducing indoor emission risks and facilitating centralized treatment, online monitoring, and maintenance / replacement.

[0047] The exhaust gas detector 10 sends a detection signal to the control center 16. When the detection result reaches a preset specific value, the control center 16 controls the gas to enter the circulating gas channel 08 through the circulating air inlet 07 and return to the distribution chamber 03 through the circulating air outlet 09 to achieve recycling. When the detection result does not reach the preset specific value, the control center 16 controls the gas to be discharged outside the cabinet under the action of the exhaust fan 06.

[0048] The preset specific values ​​include: volatile organic compound (VOC) concentration of 300-600 ppb, ozone (O3) concentration of 50-80 ppb, and relative humidity (RH) of 45-55%.

[0049] These parameters are a quantitative combination of multi-dimensional safety indicators, ensuring that the circulating gas is both safe and energy-efficient, reflecting precise control over gas quality.

[0050] This application provides a multi-layer shoe cabinet with directional air supply at the shoe opening and suction at the shoe toe. The cabinet includes: a multi-layer shoe rack, which tilts after the automatic door closes; a fan, heater, and distribution chamber located at the bottom of the cabinet, where air drawn in by the fan is heated by the heater and then enters the distribution chamber; a slit-type air outlet on each shoe rack, connected to the distribution chamber, with its airflow direction directed towards the shoe opening of the shoes placed on the rack; a suction head at the corresponding shoe toe position on each shoe rack; a sealed exhaust channel connected to each suction head, with an exhaust fan downstream of the sealed exhaust channel, creating a negative pressure zone at the suction head during operation; a detachable photocatalytic device and a detachable exhaust gas treatment device connected in series within the sealed exhaust channel; and exhaust gas treatment at the outlet of the sealed exhaust channel. The system includes: a detector; a circulating air channel connecting the outlet of the exhaust gas detector to the distribution chamber, with a circulating air inlet and a circulating air outlet at each end; a control center; wherein, the negative pressure zone formed by the exhaust fan induces the airflow from the slit-type air outlet to enter the shoe cavity through the shoe opening and flow directionally to the toe position, where it is extracted by the extraction head and enters the sealed exhaust channel; the extracted air flows sequentially through the photocatalytic device and the exhaust gas treatment device for purification before reaching the exhaust gas detector; the exhaust gas detector sends a detection signal to the control center; when the detection result reaches a preset specific value, the control center controls the gas to enter the circulating air channel through the circulating air inlet and return to the distribution chamber through the circulating air outlet for recycling; when the detection result does not reach the preset specific value, the control center controls the gas to be discharged outside the cabinet under the action of the exhaust fan. The shoe cabinet of this application achieves directional air supply, high-efficiency purification, and closed-loop control.

[0051] In one example, the control center 16 is configured to: when the detection result of the exhaust gas detector 10 reaches a preset specific value, open the recirculation air inlet 07 to allow the gas to flow back to the distribution chamber 03; when the detection result does not reach the preset specific value, close the recirculation air inlet 07 and allow the gas to be discharged from the cabinet.

[0052] The control center 16 is also used to adjust the air volume of the exhaust fan 06 according to the detection signal of the exhaust gas detector 10.

[0053] Understandably, if the exhaust gas detector fails to meet the required standards, the control center will increase the exhaust fan speed to accelerate gas removal from the cabinet. This feature enables dynamic closed-loop control, adjusting the extraction intensity based on gas quality, thus saving energy while maintaining a stable negative pressure environment.

[0054] The shoe cabinet system in this embodiment is a double-entry, double-exit, recirculating system. During operation, the automatic door 15 of the shoe cabinet closes automatically, and the tiltable shoe rack 17 enters the tilt mode with a tilt angle of 15°-30°. The rear of the shoe rack is equipped with a small partition or support structure to prevent shoes from slipping off the rack. The fans 01 on both sides of the bottom draw in air, which is heated by the heater 02 and then enters the bottom distribution chamber 03 to distribute the heated air to each layer. The air is then delivered to the shoe opening through the slit-type air outlets 04 on each layer in an upward tilt relative to the horizontal plane. The airflow enters from the shoe opening and penetrates the shoe cavity, transporting moisture and volatile pollutants inside the shoe to the toe position.

[0055] Under the negative pressure generated by the exhaust fan 06, the air inside the shoe is actively drawn out by the suction head 11 and enters the sealed exhaust channel 14 isolated from the shoe cavity space. The drawn air passes through the series-connected detachable photocatalytic device 13 and detachable exhaust gas treatment device 12 in the exhaust channel to remove the by-products and odors generated during the photocatalysis process. The treated exhaust gas passes through the exhaust gas detector 10. If it does not reach a specific value, it is all drawn out by the exhaust fan 06. The exhaust speed can be adjusted according to the exhaust gas detector.

[0056] When the exhaust gas detector 10 reaches a specific value, part of the treated gas is recycled. This gas enters the recirculation inlet 07, passes through the recirculation channel 08, and is discharged into the distribution chamber through the recirculation outlet 09, thus achieving a closed-loop circulation of gas inside the shoe cabinet. This circulation mode effectively reduces system energy consumption and heat loss within the cabinet, thereby improving overall operating efficiency.

[0057] The working route of the shoe cabinet in this application is as follows: fan 01 → heater 02 → distribution chamber 03 → slit-type air outlet 04 → shoe opening → shoe toe → exhaust head 11 → sealed channel 14 → detachable photocatalytic device 13 → detachable exhaust gas treatment device 12 → emission / reuse.

[0058] See Figure 3 This is a schematic diagram of the gas circulation route in this application. After the gas is extracted by the extraction head 11, it flows vertically upward under the action of the exhaust fan 06. At the same time, the detachable photocatalytic device 13 and the detachable exhaust gas treatment device 12 treat the extracted gas. The exhaust gas is detected by the exhaust gas detector 10. If it is qualified, it enters the circulation gas channel 08 and flows back to the distribution chamber 03 for reuse. If it is unqualified, it is discharged from the cabinet.

[0059] Secondly, embodiments of this application provide a method for directional air supply to the shoe opening and extraction to the shoe toe of a shoe cabinet, applicable to the first aspect of shoe cabinets, including: The negative pressure zone created by the exhaust fan 06 induces the airflow from the slit-type air outlet 04 to enter the shoe cavity through the shoe opening and flow directionally to the toe position. After being drawn through the suction head 11, the air enters the sealed exhaust channel 14; the extracted air flows through the photocatalytic device 13 and the exhaust gas treatment device 12 for purification treatment before reaching the exhaust gas detector 10. The exhaust gas detector 10 sends a detection signal to the control center 16. When the detection result reaches a preset specific value, the control center 16 controls the gas to enter the circulating gas channel 08 through the circulating air inlet 07 and return to the distribution chamber 03 through the circulating air outlet 09 to achieve recycling. When the detection result does not reach the preset specific value, the control center 16 controls the gas to be discharged outside the cabinet under the action of the exhaust fan 06.
