Description

Technical Field

[0001] The utility model relates to the technical field of ventilation systems, and more specifically, to an exhaust structure for a dressing room. Background Art

[0002] At present, the exhaust system of the locker room is full exhaust, with a ventilation frequency of 3 times / h, and there are many forms: one is to install a side wall exhaust fan on the side wall of the locker room to exhaust the entire locker room; the other is to install an exhaust port, exhaust duct, and exhaust fan to exhaust the locker room, and the exhaust port is generally arranged above the locker room, flush with its ceiling. Full exhaust only exhausts the entire space of the locker room, and cannot effectively remove the odor emitted from the shoe cabinet in the locker room. In view of this situation, we should study and invent an exhaust system dedicated to the shoe cabinet in the locker room. To this end, we propose a locker room exhaust structure. Utility Model Content

[0005] A dressing room exhaust structure comprises a shoe cabinet, an exhaust air deflector, an exhaust branch pipe, an exhaust passage, an exhaust main pipe, a box-type duct exhaust fan, and exhaust rainproof shutters, wherein the exhaust air deflector is arranged on the top of the shoe cabinet and completely covers the shoe cabinet; the exhaust air deflector is an umbrella-shaped air deflector; exhaust branch pipes are vertically arranged at equal intervals on the exhaust air deflector, the exhaust branch pipes are connected to the exhaust main pipe, and the exhaust main pipe is provided with a box-type duct exhaust fan; the outlet of the exhaust main pipe is connected to the exhaust rainproof shutters, and the exhaust rainproof shutters are installed on the outer wall.

[0006] Furthermore, an air volume regulating valve is installed on the exhaust branch pipe.

[0007] Furthermore, the back plate of the shoe cabinet is used as a ventilation hole plate or the bottom plate of the shoe cabinet is used as a ventilation hole plate.

[0008] Furthermore, when the back panel of the shoe cabinet is set as a ventilation hole panel, an outer back panel needs to be set outside the ventilation hole panel, and an exhaust channel is formed between the ventilation hole panel and the outer back panel.

[0009] Furthermore, mesh holes are arranged on the ventilation hole plate, and the mesh holes are metal mesh holes; the mesh holes have a size of Φ20 and are evenly arranged on the entire plate surface.

[0010] Furthermore, the shoe cabinet back panel and the outer back panel form an exhaust passage, forming a negative pressure cavity.

[0011] Furthermore, the exhaust branch pipe is a Ф50 branch pipe; the wind speed at the louver outlet of the exhaust rainproof louver is not greater than 3m / s.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model can force local exhaust of shoe cabinets, which are the main source of odor in the dressing room; it is particularly suitable for removing odor in dressing rooms for changing shoes in public places such as clean production workshops, bathrooms, stadiums, swimming pools, etc. The exhaust air deflector has an umbrella-shaped design that prevents the dirty air from overflowing, and gathers the airflow at the top of the umbrella. The inner surface of the deflector is smooth, which reduces the local resistance of the exhaust system, and has no dead angles, greatly reducing the retention space of dirty gas.

[0019] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Example

[0021] See attached Figure 1-Figure 3 A dressing room exhaust structure of this embodiment includes a shoe cabinet 1, an exhaust air deflector 2, an exhaust branch pipe 4, an exhaust channel 7, an exhaust main pipe 8, a box-type duct exhaust fan 9, and an exhaust rainproof louver 10. The exhaust air deflector 2 is arranged on the top of the shoe cabinet 1 and completely covers the shoe cabinet 1; the exhaust air deflector 2 is an umbrella-shaped hood; exhaust branch pipes 4 are vertically arranged at equal intervals on the exhaust air deflector 2, and the exhaust branch pipes 4 are connected to the exhaust main pipe 8, and the exhaust main pipe 8 is provided with a box-type duct exhaust fan 9; the outlet of the exhaust main pipe 8 is connected to the exhaust rainproof louver 10, and the exhaust rainproof louver 10 is installed on the outer wall.

[0022] Specifically, an air volume regulating valve 5 is installed on the exhaust branch pipe 4 .

[0023] The back plate of the shoe cabinet 1 is used as the ventilation hole plate 3 or the bottom plate of the shoe cabinet 1 is used as the ventilation hole plate 3 .

[0024] When the back plate of the shoe cabinet 1 is set as a ventilation hole plate 3, an outer layer back plate 6 is required to be set outside the ventilation hole plate 3, and an exhaust channel 7 is formed between the ventilation hole plate 3 and the outer layer back plate 6; Figure 2 A back plate 6 is added to the outside of the ventilation hole plate 3 to form an exhaust channel 7, forming a negative pressure cavity. The dirty air is extracted by the exhaust branch pipe 4, and the exhaust volume of each shoe cabinet is adjusted together with the air volume regulating valve 5.

[0025] See also Figure 3 The exhaust air deflector 2 is an umbrella-shaped air deflector, and its opening angle is preferably 45°. For shoe cabinets with larger side lengths, the umbrella-shaped air deflector can be set in sections. The umbrella-shaped design of the exhaust air deflector prevents the dirty air from overflowing, and gathers the airflow at the top of the umbrella. The inner surface of the deflector is smooth, which reduces the local resistance of the exhaust system and has no dead angles, greatly reducing the retention space of dirty gases. This exhaust air deflector is a closed air hood, not open on all four sides, and is integrated with the shoe cabinet, which effectively ensures the removal of dirty gases in the shoe cabinet. The wind speed of this exhaust hood is 0.3~0.5m / s. The umbrella-shaped cover is provided with a skirt, and the height of the skirt is h1=0.25√F (F is the hood opening area)

[0026] Continue to see Figure 4 In the dressing room shoe cabinet exhaust structure of the present embodiment, mesh holes are arranged on the ventilation hole plate 3, and the mesh holes are metal mesh holes; the mesh holes are Φ20 in size and are evenly arranged on the entire plate surface.

[0027] See also Figure 1, the schematic elevation diagram of the shoe cabinet exhaust structure in the dressing room, the dirty air in the shoe cabinet 1 is emitted to the shoe cabinet exhaust channel 7 through the ventilation hole plate 3, and then discharged to the outdoor rainproof shutter 10 through the umbrella-shaped exhaust shroud 2, the exhaust branch pipe 4, the exhaust main pipe 8, and the box-type duct exhaust fan 9. When the shoe cabinets are arranged in an array, the umbrella-shaped shroud can be set in sections, and each exhaust branch pipe needs to be equipped with an air volume regulating valve to adjust the air volume of the shroud of each shoe cabinet and maintain the wind balance of the exhaust system.

[0028] This new model can force local exhaust of shoe cabinets, which are the main source of odor in the dressing room; it is particularly suitable for removing odor in dressing rooms for changing shoes in public places such as clean production workshops, bathrooms, stadiums, swimming pools, etc. The exhaust air deflector has an umbrella-shaped design that prevents the dirty air from overflowing, and makes the air flow gather at the top of the umbrella. The inner surface of the deflector is smooth, which reduces the local resistance of the exhaust system, and there is no dead angle, which greatly reduces the retention space of dirty gas.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
