Abstract

The present invention discloses a shoe cabinet air bag assembly for jet drying shoe soles under a positive pressure external exhaust and negative pressure internal environment. The air bag assembly is installed in the shoe cabinet body, and an air inlet structure, an air outlet structure and a shoe mouth jet structure connected to the internal air bag cavity are respectively provided on the air bag assembly, and an exhaust unit is installed at the air inlet structure. Under the exhaust action of the exhaust unit, the air in the shoe cabinet body is drawn into the air bag cavity through the air inlet structure to form a positive pressure. The air under the positive pressure state is divided into two paths. One path is discharged through the air outlet structure. The interior of the shoe cabinet body is always in a negative pressure state, which blocks the dirty air inside the shoe cabinet from leaking to the outside. The other path of air is ejected to the corresponding shoe mouth below through the shoe mouth jet structure. After being reflected by the sole of the shoe, the jet diffuses, slows down and refluxes in the ventilation blind area in front of the shoe sole. Then, the sweat-soaked air in the shoe sole is carried out of the shoe mouth, achieving a good drying, dehumidifying and deodorizing effect.

[0036] At least one shoe and boot processing layer and a plurality of shoe and boot storage layers are provided in the shoe cabinet; the shoe cabinet air bag assemblies are mounted on the back plate and / or top plate of the shoe and boot processing layer in a one-to-one correspondence.

[0037] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0038] 1. The shoe cabinet operates under negative pressure throughout the entire process without leaking dirty air. One embodiment of the present invention installs an air bag assembly into the shoe cabinet, and respectively provides an air inlet structure, an air outlet structure, and a shoe mouth jet structure connected to the air bag cavity therein on the air bag assembly, and installs an exhaust unit at the air inlet structure. Under the exhaust action of the exhaust unit, the air inside the shoe cabinet is drawn into the air bag cavity through the air inlet structure and forms a positive pressure in the air bag cavity. The air under the positive pressure state is divided into two paths, one of which is discharged through the air outlet structure. Under the exhaust action of the exhaust unit and the exhaust action of the air outlet structure, the interior of the shoe cabinet is always in a negative pressure state, and no dirty air will leak out of the shoe cabinet throughout the entire process. The ambient air outside the shoe cabinet will be pressed into the shoe cabinet under the action of atmospheric pressure to provide fresh air.

[0039] 2. Jet air outlet, good drying, dehumidification and deodorization effects---Under the extraction action of the extraction unit, the air in the shoe cabinet is drawn into the air bag cavity through the air inlet structure and forms a positive pressure in the air bag cavity. The other air under the positive pressure state is ejected to the corresponding shoe opening below through the shoe opening jet structure; the cross-section of the air bag cavity is large, so that the inlet pressure of each shoe opening jet structure on the air bag assembly is the same and stable, and the temperature, humidity and speed of the air (jets) injected into the sole of the shoe by each shoe opening jet structure are the same or similar. After being reflected by the sole of the shoe, the jet diffuses, slows down and refluxes in the ventilation blind area in front of the sole of the shoe, and then carries the sweat-soaked air in the sole of the shoe out of the shoe opening, achieving good drying, dehumidification and deodorization effects.

[0040] 3. The internal circulation air path is short and the efficiency is high---When the air inside the shoe cabinet circulates internally, the exhaust unit inhales the air inside the shoe cabinet and pressurizes it into the air bag assembly. The air bag assembly is in a positive pressure state. The air in the air bag cavity is injected into the soles of each shoe through each jet nozzle and then discharged outside the shoe, and then flows back to the air intake of the exhaust unit, completing a complete internal circulation process; the air internal circulation path is short, the resistance along the way is small, and the circulation efficiency is high.

DETAILED DESCRIPTION

[0056] The following is a detailed description of the shoe cabinet air bag assembly for jet drying shoe soles in a positive pressure external exhaust and negative pressure internal environment proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0057] Example 1

[0058] See Figures 1 to 5 、 Figures 9 to 11 In one embodiment, a shoe cabinet air bag assembly for jet drying shoe soles in a positive pressure external exhaust air negative pressure internal environment is used to be configured in a shoe cabinet body 9, including an air bag assembly 1 and an exhaust unit.

[0059] The air bag assembly 1 is designed to be installed in the shoe cabinet body 9. The air bag assembly 1 contains an air bag cavity, and is equipped with an air inlet structure connected to the ventilation cavity. The air bag assembly 1 is also equipped with an air outlet structure that connects the ventilation cavity to the outside world. In addition, the bottom surface of the air bag assembly 1 is equipped with several shoe opening jet structures that communicate with the air bag cavity. The shoe opening jet structures correspond one-to-one with the placement of shoes and boots in the shoe cabinet body 9.

[0060] The exhaust unit is installed correspondingly to the air inlet structure, and is used to input the air in the shoe cabinet body 9 into the air bag cavity through the exhaust unit structure.

[0061] Under the exhaust action of the exhaust unit, the air in the shoe cabinet body 9 is drawn into the air bag cavity through the air inlet structure and forms a positive pressure in the air bag cavity. The air under the positive pressure state is divided into two paths.

[0062] The air is jetted through the shoe opening jet structure to the corresponding shoe opening below. The cross-section of the air bag cavity is large, so that the inlet pressure of each shoe opening jet structure on the air bag assembly 1 is the same and stable. The temperature, humidity and speed of the air (jets) injected into the sole of the shoe by each shoe opening jet structure are the same or similar. After being reflected by the sole, the jet diffuses, slows down and refluxes in the ventilation blind area in the front of the sole of the shoe, and then carries the sweat-soaked air in the sole of the shoe out of the shoe opening, which has a good drying, dehumidifying and deodorizing effect.

[0063] The other way is discharged through the air outlet structure, and under the extraction effect of the extraction unit and the exhaust effect of the air outlet structure, the interior of the shoe cabinet body 9 is always in a negative pressure state, and no dirty air will leak out from the shoe cabinet body 9 during the whole process. The ambient air outside the shoe cabinet will be pressed into the shoe cabinet body 9 under the action of atmospheric pressure to provide fresh air.

[0064] The specific structure of the shoe cabinet air bag assembly for jet drying shoe soles in a positive pressure external exhaust and negative pressure internal environment of this embodiment is further described below:

[0065] In this embodiment, the aforementioned exhaust unit may be a forward-inclined multi-blade centrifugal fan 2 or a backward-inclined outer rotor centrifugal fan 10 .

[0066] When the exhaust unit is a forward-inclined multi-blade centrifugal fan 2, the air inlet structure is an air inlet opened at any end of the air bag assembly 1 in the length direction of the shoe cabinet body 9. The air bag assembly 1 can be specifically configured to include a back panel, a top panel, an arc-shaped panel, and two side panels. The back panel, the top panel, and the arc-shaped panel are sequentially connected to form a columnar space extending in the horizontal direction. The two side panels are respectively arranged on both sides of the columnar space and are respectively connected to the back panel, the top panel, and the arc-shaped panel to form a sealed air bag cavity. The air inlet can be opened on any of the above-mentioned side panels, and the forward-inclined multi-blade centrifugal fan 2 can also be fixed to the side panel.

[0067] When the exhaust unit is a backward-inclined outer rotor centrifugal fan 10, the air inlet structure can be an air inlet opened on the bottom surface of the air bag assembly 1. The backward-inclined outer rotor centrifugal fan 10 is installed in the air bag cavity and is arranged corresponding to the air inlet. In this case, the air bag assembly 1 can specifically include a front plate, a top plate, a back plate, and a bottom plate connected in sequence. The four plates cooperate to form a columnar space, and side plates are also arranged on both sides to form a sealed air bag cavity. Specifically, a recessed portion can extend downward from the bottom plate, and the air inlet is opened in this recessed portion. The backward-inclined outer rotor centrifugal fan 10 can be arranged in this recessed portion, and the air in the shoe cabinet body 9 is sucked in through the air inlet and thrown into the air bag cavity.

[0068] In this embodiment, the shoe cabinet air bag assembly may further include an electric auxiliary heating unit 3. The electric auxiliary heating unit 3 is provided at the air inlet channel of the exhaust unit and is used to heat the air entering the air bag cavity.

[0069] Specifically, in the case of a forward-inclined multi-blade centrifugal fan 2, the electric auxiliary heating unit 3 can be installed on the side panel corresponding to the forward-inclined multi-blade centrifugal fan 2 to heat the air drawn into the forward-inclined multi-blade centrifugal fan 2. In the case of a backward-inclined outer rotor centrifugal fan 10, the electric auxiliary heating unit 3 can be installed on the bottom surface of the bottom plate, opposite the air inlet, to heat the air drawn into the air inlet.

[0070] In this embodiment, the above-mentioned air outlet structure may specifically include an air outlet 5 and a positive pressure sewage discharge pipeline 8 opened on the air bag assembly 1.

[0071] The first end of the positive pressure sewage pipe 8 is connected to the air outlet 5; the second end of the positive pressure sewage pipe 8 passes through the shoe cabinet body 9, and the second end of the positive pressure sewage pipe 8 is connected to the building exhaust pipe or extends out of the building facade.

[0072] Specifically, the air outlet structure may further include a damper assembly 6 for adjusting the air outlet flow rate.

[0073] The damper assembly 6 includes a driver 601 and a damper slide 602. A slide rail extending to the air outlet 5 is provided on the inner wall of the air bag cavity. The damper slide 602 is slidably connected to the slide rail to close the air outlet 5. The driver 601 is disposed within the air bag cavity, and the output end of the driver 601 is connected to the damper slide 602, driving the damper slide 602 toward or away from the air outlet 5.

[0074] Furthermore, an air outlet hole 603 is provided on the damper slide 602, and the cross-sectional area of ​​the air outlet hole 603 is significantly smaller than the cross-sectional area of ​​the positive pressure sewage pipe 8, so that when the damper closes the air outlet 5, air can still be output from the wind bag cavity through the air outlet hole 603 and the air outlet 5, maintaining a slightly negative pressure state inside the shoe cabinet body 9.

[0075] In this embodiment, the shoe opening jet structure includes a jet port 4 and a jet nozzle 7 formed on the bottom surface of the air bag assembly 1. The first end of the jet nozzle 7 is connected to the jet port 4, and the second end of the jet nozzle 7 is arranged toward the shoe opening where the shoe is placed.

[0076] The jet nozzle 7 may contain a thin-diameter pipe with a very small flow cross-section, so that the air in the air bag cavity can be injected into the sole of the shoe through the shoe opening in the form of a jet.

[0077] Example 2

[0078] See Figure 6 、 Figure 7 、 Figure 12 and Figure 13 This embodiment provides an operating method for the shoe cabinet air bag assembly for jet drying shoe soles in a negative pressure internal environment with positive pressure external exhaust air in the first embodiment. The aforementioned air flow regulating unit is the damper assembly 6 in the first embodiment.

[0079] In drying mode, the damper slide 602 slides to the air outlet 5, and the positive pressure air in the air bag cavity is output through the air outlet 603 on the damper slide 602. The air flow rate is small, and the exhaust unit and the electric auxiliary heating unit 3 are activated. The slightly warm hot air is pressed into the air bag assembly 1 by the exhaust unit. The main air is injected into the shoe opening of the corresponding shoe or boot through the shoe opening jet structure and decelerated and diffused in the sole of the shoe. It carries the sweat and moisture in the sole of the shoe and is discharged from the shoe opening and collected in the shoe cabinet body 9. It is heated again by the electric auxiliary heating unit 3 and then sucked into the exhaust unit again to start the next cycle. In drying mode, the air bag assembly 1 in the positive pressure state continuously discharges a small amount of air in the air bag assembly 1 to the outdoors through the small air flow rate adjusted by the air outlet 603, causing the air in the shoe cabinet body 9 to continuously decrease, so that the shoe cabinet body 9 is continuously in a slightly negative pressure state.

[0080] In the exhaust mode, when the air in the air bag assembly 1 absorbs moisture from the soles of shoes and the humidity reaches a threshold, or when the preset time interval of the drying mode expires, the electric auxiliary heating unit 3 stops heating, the damper slider 602 slides away from the air outlet 5, and the positive pressure air in the air bag cavity is discharged through the air outlet 5 at a high air flow rate. The extraction unit continues to operate, extracting and pressurizing the dirty air from the soles of shoes and the shoe cabinet body 9, injecting it into the air bag assembly 1, and then exhausting it to the outdoors through the air outlet structure at a high air flow rate regulated by the air flow control unit. In the exhaust mode, because the dirty air is largely pressurized and discharged, the negative pressure in the shoe cabinet body 9 becomes even lower, pulling the ambient air outside the shoe cabinet into the shoe cabinet body 9 at a rapid rate.

[0081] Example 3

[0082] See Figure 8 and Figure 14 This embodiment provides a shoe cabinet that uses the shoe cabinet air bag assembly for jet drying of shoe soles under the positive pressure external exhaust air and negative pressure internal environment of the above-mentioned embodiment one.

[0083] At least one shoe and boot treatment layer and several shoe and boot storage layers are provided in the shoe cabinet. The shoe and boot treatment layer is used for drying, dehumidifying and deodorizing shoes and boots.

[0084] The shoe cabinet air bag assemblies are mounted one-to-one on the back and / or top panels of the shoe treatment layer. When using a forward-inclined multi-blade centrifugal fan 2, the air bag assembly 1 can be mounted to the back panel of the shoe treatment layer via the back panel; when using a backward-inclined outer rotor centrifugal fan 10, the air bag assembly 1 can be mounted to the top panel of the shoe treatment layer via the top panel.

[0085] Usually, the shoe and boot processing layer is used to place some frequently worn shoes and boots, so it is generally set on the top layer or upper part of the shoe cabinet for daily use. In order to allow fresh air to enter the shoe cabinet body 9 smoothly, a fresh air vent for allowing external air to enter can be opened at the bottom layer or lower part of the cabinet body.

[0086] Therefore, the shoe cabinet of this embodiment has the functions of dehumidifying, deodorizing, drying and storing shoes and boots, and meets the needs of shoe and boot care and storage at the same time.

[0087] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the scope of protection of the present invention.
