Description

Technical Field

[0001] This utility model belongs to the field of green energy-saving technology, and in particular relates to a shoe cabinet air bag assembly and a shoe cabinet with positive pressure external sewage exhaust and negative pressure internal environment jet drying. Background Technology

[0002] The prior art discloses a shoe cabinet air bag assembly (publication number CN116066384A) that uses positive pressure external exhaust air and negative pressure internal environment for jet drying of shoe soles. This assembly is installed inside the shoe cabinet, and features an air inlet structure, an air outlet structure, and a shoe opening jet structure connected to the air bag cavity. An exhaust unit is installed at the air inlet structure. Under the exhaust action of the exhaust unit, air inside the shoe cabinet is drawn into the air bag cavity through the air inlet structure, creating positive pressure. The air under positive pressure is divided into two paths, one of which is discharged through the air outlet structure, ensuring that the inside of the shoe cabinet is always under negative pressure. The system uses a single centrifugal fan to prevent the leakage of stale air from inside the shoe cabinet. Another airflow is directed through the shoe opening jet structure to the corresponding shoe opening below. After being reflected by the sole, the jet diffuses, slows down, and flows back in the ventilation blind spot at the front of the shoe, carrying away the sweaty air from the sole and flowing out of the shoe opening. This air then merges with the fresh air entering the shoe cabinet from the environment and is drawn back into the exhaust unit, starting a new cycle. This technology uses only one centrifugal fan to achieve "positive pressure external exhaust of stale air and negative pressure internal jet drying," preventing the leakage and pollution of stale air from inside the shoe cabinet to the external environment, resulting in excellent drying, dehumidification, and deodorization effects.

[0003] However, this existing technology still has some technical problems that need to be improved, such as:

[0004] ① An electric damper is still required. This technology uses the opening and closing of the electric damper to achieve two operating modes: large-volume external exhaust and internal circulation drying. The electric damper increases the manufacturing cost and maintenance complexity of the shoe cabinet.

[0005] ② There is still energy waste. This technology uses an electric heating module to heat the air to achieve jet drying of the shoe sole. However, the electric heating module is located at the air inlet of the centrifugal fan, which causes the internal circulating drying airflow injected into the shoe sole and the external exhaust airflow discharged into the outdoor atmosphere to be heated at the same time. The heat carried away by the external exhaust airflow is obviously a waste of energy. Utility Model Content

[0022] The wall of the first positive pressure chamber is provided with a through hole for assembling the air outlet structure. One end of the air outlet structure is placed inside the first positive pressure chamber, and the other end passes through the through hole.

[0023] The second positive pressure chamber is provided with a number of air outlet holes for discharging airflow; the air outlet holes are connected to the jet unit.

[0024] Furthermore, the air outlet structure is a narrow-diameter throttling sewage pipe with a small inner diameter and a long length, which has a throttling effect on the external sewage exhaust air.

[0025] Preferably, the narrow-diameter throttling sewage pipe is a coilable and / or retractable pipe.

[0026] Preferably, the narrow-diameter throttling sewage pipe is composed of multiple detachable narrow-diameter pipe segments connected together.

[0027] Furthermore, the horizontal cross-section of the cavity is square, circular, elliptical, or triangular.

[0028] Furthermore, the cavity is square and is also provided with a second partition; the second partition, together with the airflow-passing partition and / or the electric heating unit, separates the cavity into a first positive pressure cavity and a second positive pressure cavity that are interconnected.

[0029] The second positive pressure chamber is L-shaped; the bottom plate of the second positive pressure chamber is provided with several air outlet holes for discharging airflow, which are connected to the jet unit.

[0030] Furthermore, the air outlet is connected to the jet unit via a pipe; the pipe is a coilable and / or retractable and positionable pipe.

[0032] The shoe cabinet air bag assembly is located at the top inside the shoe storage cavity; the air intake of the exhaust unit is connected to the shoe storage cavity and is used to draw air from the shoe storage cavity into the cavity to form a positive pressure cavity.

[0033] A fresh air inlet is provided on the bottom plate or side plate of the shoe cavity;

[0038] Furthermore, the shoe cabinet is provided with multiple shoe storage cavities, and at least two shoe storage cavities are provided with the shoe cabinet air bag assembly; each of the air outlet structures is connected to the external sewage pipe of the shoe cabinet through an external sewage exhaust check valve.

[0039] A method for using a shoe cabinet with positive pressure external exhaust and negative pressure internal environment jet drying includes the following steps:

[0040] When the extraction unit is activated, it draws in air from the shoe cavity, pressurizes it, and discharges it into the cavity of the shoe cabinet air intake assembly. The airflow discharged into the cavity runs along two paths:

[0041] Part of the airflow, after being depressurized by the air outlet structure, enters the sewage pipe outside the shoe cabinet and is discharged into the outdoor atmosphere, achieving positive pressure external sewage exhaust; the shoe-holding cavity inside the shoe cabinet, connected to the air intake of the exhaust unit, generates negative pressure, which pulls the outside air of the shoe cabinet into the shoe-holding cavity through the fresh air inlet, preventing the polluted air in the shoe-holding cavity from being discharged into the indoor environment outside the shoe cabinet.

[0042] Another part of the airflow flows through the electric heating unit and / or jet unit, and blows air towards the soles of the shoes inside the shoe cavity through several jet nozzles. The stale air and sweat vapor emitted by the shoes and boots are then combined with the fresh air from outside the shoe cabinet that is supplied from the fresh air inlet. The fresh air is then drawn in again by the exhaust unit, pressurized and discharged into the cavity to start a new cycle.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] This invention provides a shoe cabinet with a positive pressure external exhaust and a negative pressure internal environment for waste air, which utilizes the flow resistance of a narrow-diameter throttling sewage pipe to adjust the proportion of waste air exhaust. Compared with existing technologies, it has outstanding substantive features and significant progress:

[0045] ① Improve reliability, economy, and accessibility

[0046] This invention replaces the electric damper in the prior art with a narrow-diameter throttling sewage pipe, enabling the parallel operation of two modes: positive pressure external sewage exhaust and negative pressure internal environment jet drying. This significantly reduces the manufacturing cost and technical complexity of the shoe cabinet, and greatly improves its technical reliability, economy, and popularity.

[0047] ② The shoe cabinet has been improved to accommodate external exhaust pipes for polluted air.

[0048] This invention features a longer, narrow-diameter throttling sewage pipe. During shoe cabinet installation, the length of the narrow-diameter throttling sewage pipe is compensated and corrected by referring to the inner diameter, length, and airflow resistance of the external sewage exhaust pipe. This allows for adjustment and control of the proportion of external sewage air volume in the total exhaust volume of the centrifugal fan. If the external sewage exhaust pipe is short, has a large diameter, and low resistance to the sewage airflow, the narrow-diameter throttling sewage pipe in the first positive pressure chamber is kept longer; conversely, it is kept shorter. By setting a longer, narrow-diameter throttling sewage pipe in the first positive pressure chamber for cutting and shortening, this invention increases the adaptability of the shoe cabinet's positive pressure external sewage exhaust negative pressure internal environment jet drying system to different external sewage exhaust pipe layouts, structures, lengths, and resistances.

[0049] ③ Reduced heat loss in the shoe drying cabinet

[0050] This invention places a narrow-diameter throttling sewage pipe in the first positive pressure chamber of the shoe cabinet and places the electric heating module in the through hole in the partition between the first and second positive pressure chambers of the shoe cabinet; the sewage air discharged by the narrow-diameter throttling sewage pipe is not heated, and all the heated air enters the second positive pressure chamber and is injected into the sole of the shoe; compared with the prior art, it eliminates the energy waste caused by heating the external sewage air and reduces the heat loss of the drying shoe cabinet.

[0063] Example 1

[0064] like Figures 1-3 As shown, a shoe cabinet air vent assembly includes a positive pressure cavity 1, which forms a flow channel for airflow.

[0065] The extraction unit 2 is connected to the cavity and is used to draw air into the cavity to form a positive pressure chamber;

[0066] Air outlet structure 3 is located in the cavity and connected to the outside of the cavity, and is used to exhaust part of the air inside the cavity;

[0067] Jet unit 4 is connected to the cavity and is used to expel air from the cavity;

[0068] The controller is used to control the operation of the shoe cabinet air conditioning assembly.

[0069] The cavity 1 is equipped with a baffle 11 that allows airflow and an electric heating unit 12, which are used to divide the cavity 1 into two connected positive pressure chambers.

[0070] Two interconnected positive pressure chambers, namely the first positive pressure chamber 13 and the second positive pressure chamber 14, are used to form a flow channel for airflow.

[0071] In this embodiment, the cavity 1 is rectangular and is also provided with a second partition 15; the second partition 15, together with the airflow-passing partition 11 and the electric heating unit 12, divides the cavity into a first positive pressure cavity 13 and a second positive pressure cavity 14 that are interconnected.

[0072] The second positive pressure chamber 14 is L-shaped;

[0073] The extraction unit 2 is located in the first positive pressure chamber 13 and is used to draw air into the chamber to form two positive pressure chambers;

[0074] The air outlet structure 3 is disposed in the first positive pressure chamber 13 and is used to discharge part of the air in the first positive pressure chamber;

[0075] The jet unit 4 is connected to the second positive pressure chamber 14 and is used to discharge the air in the second positive pressure chamber.

[0076] In this embodiment, the extraction unit 2 is selected from a centrifugal fan, and more specifically, a backward-inclined external rotor centrifugal fan.

[0077] The first positive pressure chamber 13 is provided with an air inlet 131 for assembling the exhaust unit 2, and the air inlet of the exhaust unit 2 is matched with the air inlet 131.

[0078] The wall of the first positive pressure chamber 13 is provided with a through hole for assembling the air outlet structure 3. One end of the air outlet structure 3 is placed in the first positive pressure chamber, and the other end passes through the through hole.

[0079] The bottom plate of the second positive pressure chamber 14 is provided with several air outlet holes 141 along the long side of the shoe cabinet for discharging airflow; the air outlet holes 141 are connected to the jet unit 4. The jet nozzle of the jet unit 4 is directed toward the shoe opening of the shoes to be dried in the shoe placement cavity of the shoe cabinet.

[0080] In this embodiment, the air outlet structure 3 is a narrow-diameter throttling sewage pipe with a small inner diameter and a long length, which has a throttling effect on the external sewage exhaust air.

[0081] Small-diameter throttling sewage pipes are coilable and / or retractable pipes.

[0082] This embodiment features a longer, narrow-diameter throttling sewage pipe. During shoe cabinet installation, the length of the narrow-diameter throttling sewage pipe is compensated and corrected based on the inner diameter, length, and airflow resistance of the external sewage exhaust pipe. This allows for adjustment and control of the proportion of external sewage air volume in the total exhaust volume of the centrifugal fan. If the external sewage exhaust pipe of the shoe cabinet is short, has a large diameter, and low resistance to the sewage airflow, the narrow-diameter throttling sewage pipe in the first positive pressure chamber is kept longer; conversely, it is kept shorter. This invention increases the adaptability of the shoe cabinet's positive pressure external sewage exhaust negative pressure internal environment jet drying system to different external sewage exhaust pipe layouts, structures, lengths, and resistances by setting a longer, narrow-diameter throttling sewage pipe in the first positive pressure chamber for cutting and shortening.

[0083] Example 2

[0084] This implementation shares the same technical principle as Example 1. Both are based on the principle of "using only one centrifugal fan to simultaneously drive two air paths: positive pressure external exhaust air and negative pressure internal environment jet drying." Three cavities are set up: a first positive pressure cavity 13, a second positive pressure cavity 14, and a shoe placement cavity 51. A narrow-diameter throttling exhaust pipe is installed in the first positive pressure cavity 13 instead of the electric damper in the prior art. Furthermore, the electric heating unit 12 is placed in the airflow channel after the first positive pressure cavity 13 to reduce the heat carried by the external exhaust air.

[0085] like Figure 4 As shown, the difference in this embodiment is that the cavity of the second positive pressure chamber 14 along the long side of the shoe cabinet is located from the rear of the first positive pressure chamber 13 in embodiment 1 to the front of the first positive pressure chamber 13. During operation, part of the airflow in the first positive pressure chamber 13 flows through the electric heating unit 12, is heated and becomes dry air with reduced relative humidity and increased drying capacity, and then flows into the second positive pressure chamber 14. It passes through several jet nozzles located at the bottom of the second positive pressure chamber 14 and located in front of the shoe cabinet along the long side of the shoe cabinet, and is injected into the shoe opening of the shoes to be dried, heating and drying the shoes and removing the dirty air and foot sweat vapor in the shoes. Then it is combined with the fresh air from outside the shoe cabinet that is replenished from the fresh air inlet and is sucked in again by the centrifugal fan to start a new cycle.

[0086] The narrow-diameter throttling sewage pipe route is composed of multiple detachable narrow-diameter pipe sections connected together.

[0087] Example 3

[0088] This implementation shares the same technical principle as Example 1. Both are based on the principle of "using only one centrifugal fan to simultaneously drive two air paths: positive pressure external exhaust air and negative pressure internal environment jet drying." Three cavities are set up: a first positive pressure cavity 13, a second positive pressure cavity 14, and a shoe placement cavity 51. A narrow-diameter throttling exhaust pipe is installed in the first positive pressure cavity 13 instead of the electric damper in the prior art. Furthermore, the electric heating unit 12 is placed in the airflow channel after the first positive pressure cavity 13 to reduce the heat carried by the external exhaust air.

[0089] like Figure 5 As shown, the difference in this embodiment is that the horizontal cross-section of cavity 1 is circular.

[0090] The cavity 1 is equipped with a baffle 11 that allows airflow to pass through, which is used to divide the cavity 1 into two connected positive pressure cavities.

[0091] The air outlet 141 is connected to the jet unit 4 via a pipe; the pipe is a coilable and / or retractable and positionable pipe.

[0092] Example 4

[0093] like Figure 6-7 As shown, a shoe cabinet with positive pressure external exhaust air and negative pressure internal environment jet drying is provided by the shoe cabinet air bag assembly of Embodiment 1. The shoe cabinet has 2 layers and 2 shoe placement cavities.

[0094] The shoe cabinet air bag assembly is located at the top inside the shoe cavity 51; the air intake of the exhaust unit 2 is connected to the shoe cavity 51 and is used to draw the air from the shoe cavity 51 into the cavity 1 to form a positive pressure cavity.

[0095] A fresh air inlet 511 is provided on the bottom plate or side plate of the shoe cavity 51;

[0096] In this embodiment, the fresh air inlet 511 is located away from the exhaust unit 2.

[0097] The jet unit 4 is used to expel the air from the cavity 1 and blow air toward the sole of the shoe in the shoe cavity 51;

[0098] The air outlet structure 3, together with the external sewage pipe of the shoe cabinet, is used to exhaust some of the air inside the cavity 1.

[0099] The air outlet structure 3 is equipped with an external sewage return valve 31.

[0100] Given that athlete's foot is contagious, this embodiment uses a shoe cabinet with a single-layer positive pressure external exhaust and negative pressure internal environment jet drying technology. This could lead to the mixing of polluted air discharged from the shoes of different family members placed in the same shoe compartment 51 during the drying process. If the polluted air discharged from the shoes of family members with athlete's foot is mixed and then circulated during the drying process, it could enter the shoes of healthy family members, causing cross-infection of athlete's foot bacteria. This embodiment uses a double-layer structure with positive pressure external exhaust and negative pressure internal environment jet drying shoe cabinet. The shoes of healthy family members and those with athlete's foot are placed in separate layers, in two different shoe compartments where the drying airflow operates independently. Furthermore, an external exhaust check valve 31 is installed at the connection point between the narrow-diameter throttling exhaust pipe of the first positive pressure 13 corresponding to each shoe compartment and the external exhaust pipe of the shoe cabinet. This prevents the external exhaust air of the drying layer from flowing back into the shoe compartment of the stopped drying layer, thus preventing cross-infection of athlete's foot bacteria.

[0101] The external sewage air check valve 31 in this embodiment can be gravity-driven, spring-driven, or electric.

[0102] A method for using a shoe cabinet with positive pressure external exhaust and negative pressure internal environment jet drying includes the following steps:

[0103] The exhaust unit 2 is activated, drawing in air from the shoe cavity 51, pressurizing it, and then discharging it into the cavity 1 of the shoe cabinet air bag assembly. The airflow discharging into the cavity 1 runs along two paths:

[0104] Part of the airflow, after being depressurized by the air outlet structure 3, enters the sewage pipe outside the shoe cabinet and is discharged into the outdoor atmosphere, achieving positive pressure external sewage exhaust; the shoe cavity 51 inside the shoe cabinet, which is connected to the air intake of the exhaust unit 2, generates negative pressure, which pulls the air outside the shoe cabinet into the shoe cavity 51 through the fresh air inlet 511, preventing the polluted air in the shoe cavity 51 from being discharged into the indoor environment outside the shoe cabinet.

[0105] Another part of the airflow flows through the electric heating unit and / or jet unit 4, and blows air towards the soles of the shoes inside the shoe cavity through several jet nozzles. The stale air and sweat vapor emitted by the shoes and boots are then combined with the fresh air from outside the shoe cabinet that is replenished from the fresh air inlet 511, and are drawn back into the cavity by the exhaust unit 2, pressurized and discharged, to start a new cycle.

[0106] Example 5

[0107] like Figure 8 As shown, the shoe cabinet in this embodiment, which uses a positive pressure external exhaust air and a negative pressure internal environment jet drying system, is similar to that in embodiment 4. The difference is that the shoe cabinet has multiple layers and multiple shoe placement cavities 51; each shoe placement cavity 51 is equipped with a shoe cabinet air package assembly; and each air outlet structure 3 is connected to the external sewage pipe of the shoe cabinet through an external sewage exhaust air check valve 31.

[0108] This embodiment features multiple shoe drying layers, each independently implementing positive pressure external exhaust air and negative pressure internal environment jet drying, resulting in a larger shoe drying capacity and greater flexibility.

[0109] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
