[0001] The invention belongs to the technical field of exhaust equipment, and in particular relates to an exhaust device for a dry cleaning room. Background Art

[0002] A dry cleaning room is a place dedicated to dry cleaning operations, primarily using chemical solvents to clean clothing, fabrics, and other items. It's suitable for fabrics that are sensitive to water, prone to shrinkage, or deformation, or are made of unusual materials, such as wool, silk, fur, and suits. The solvents typically used are tetrachloroethylene and petroleum olefin. For some special stains, unconventional solvents such as sulfuric acid, hydrochloric acid, or acetone may also be used. Because unconventional solvents are highly hazardous and volatile, the dry cleaning room must be ventilated during use to prevent harm from inhalation.

[0003] The current exhaust method is to open windows and use natural wind for ventilation. However, with the increasing frequency of daily use of hazardous solvents, natural ventilation can no longer meet the requirements. This independent mechanical exhaust device can effectively meet the needs.

[0007] Preferably, the exhaust system includes an exhaust duct, one end of which is located in the confined space and is connected to the first low-pressure cavity on the wall panel. An adsorption box is provided at the end of the exhaust duct located outside the confined space, and an adsorption filler is fixedly installed in the adsorption box. An exhaust fan is fixedly installed on the side wall of the adsorption box, and the exhaust fan is used to extract the gas in the confined space. When the gas in the exhaust duct passes through the adsorption box, it will pass through the adsorption filler.

[0008] This arrangement connects the exhaust system to the wall panel's first low-pressure chamber via the exhaust duct, efficiently extracting gas from the confined space. The adsorption box and adsorption packing effectively remove harmful substances from the gas, preventing environmental pollution. The exhaust fan provides stable suction force, ensuring smooth gas flow. Furthermore, the design of the gas passing through the adsorption packing prolongs contact time, enhances adsorption efficiency, and ensures cleaner exhaust gas.

[0010] With this setup, the air inlet duct draws in air from the outside, and the regulating components within the conditioning box precisely control the temperature and humidity of the air entering the space to meet the needs of different environments. The filter element removes impurities from the air, ensuring the quality of the air entering the space. Air inlets are evenly distributed along the sidewalls of the duct, ensuring that the treated air is evenly distributed throughout the confined space, preventing localized poor air quality.

[0011] Preferably, the control system includes an inlet temperature sensor, an exhaust temperature sensor and a gas concentration sensor electrically connected to the control panel, the control panel and the gas concentration sensor are both located in the confined space, the gas concentration sensor is used to detect the target gas concentration in the confined space, the inlet temperature sensor is located in the air inlet pipe at the air inlet, and is used to collect the inlet temperature data of the air sent into the confined space, and the exhaust temperature sensor is located in the first low-pressure chamber, and is used to collect the exhaust temperature data discharged from the confined space.

[0012] This setup enables real-time monitoring of key parameters within the confined space through a variety of sensors. Gas concentration sensors promptly detect target gas concentrations, providing a basis for the control system to adjust intake and exhaust air. Inlet and exhaust temperature sensors monitor intake and exhaust air temperatures, respectively, helping to precisely control the temperature environment within the space. The control panel coordinates the intake and exhaust systems based on data from these sensors, achieving intelligent and precise environmental control.

[0014] With this setup, the tabletop and wall panels are bolted together, ensuring structural stability. Sealing strips are installed at the joints to effectively prevent air leakage and ensure the airtight seal of the suction assembly. The support frame provides additional support for the tabletop, enhancing the structural load-bearing capacity and extending its service life while also ensuring the proper functioning of the suction assembly.

[0015] Preferably, first air suction holes are provided on the side walls of the wall panel above and below the table top.

[0016] With this configuration, first suction holes are located on both the upper and lower sides of the wall panels, expanding the suction range. They not only absorb exhaust gas near the desk, but also capture gas at different heights in the space, effectively treating the air in the entire enclosed space and improving the effectiveness and comprehensiveness of air purification.

[0017] Preferably, the plurality of air suction components are evenly distributed on the inner wall of the enclosed space, and the materials of the air suction components, the air inlet pipe and the air exhaust pipe are all modified polyvinyl chloride.

[0018] This configuration ensures that the modified PVC material exhibits excellent corrosion resistance and stability, is also anti-static, and adapts to diverse environmental conditions. Using this material for the suction components, air inlet ducts, and exhaust ducts extends the equipment's lifespan and reduces maintenance costs. The evenly distributed suction components optimize airflow distribution within the space, further improving air handling efficiency.

[0019] Preferably, the filter element is made of cotton fiber, and the adsorption filler is activated carbon.

[0020] With this setup, the cotton fiber filter element has excellent filtration performance, effectively intercepting dust and impurities in the air, ensuring the quality of the air entering the room.

[0021] Preferably, a sub-control solenoid valve is respectively provided at the connection between each suction component and the exhaust duct, and the sub-control solenoid valve is electrically connected to the control panel. An indicator light and a sub-control switch are fixedly provided on the wall panel, and the indicator light and the sub-control switch are both electrically connected to the sub-control solenoid valve.

[0022] This configuration allows for independent control of each suction component. Workers can use the separate control switches to select the appropriate solenoid valve for each suction component to exhaust harmful gases based on their specific work location. Indicator lights provide intuitive visibility into the suction component's operating status. This improves the system's flexibility and adaptability, ensuring it meets operational needs while also saving energy and reducing consumption, ultimately lowering production costs.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1-6As shown, a dry cleaning room exhaust device includes an air intake system 1, an exhaust system 2, and a control system 4. The output of the air intake system 1 and the input of the exhaust system 2 are located in the same enclosed space 5, forming a closed-loop air circulation path. The enclosed space 5 is the dry cleaning room. The air intake system 1 delivers treated air into the enclosed space 5, and the exhaust system 2 exhausts the gas in the enclosed space 5. The two systems work together through the control system 4. The control system 4 adjusts the air supply volume and air temperature of the air intake system 1 and the exhaust volume of the exhaust system 2 based on the environmental parameters of the enclosed space 5 to ensure stable air quality in the enclosed space 5.

[0030] The air inlet system 1 in the confined space 5 is provided with a number of air suction components, such as Figure 5 and Figure 6 As shown, the suction assembly includes a wall panel 23 and a table panel 24. The wall panel 23 is set on the inner wall of the enclosed space 5 and is provided with a first low-pressure chamber 30 therein. A plurality of first suction holes 25 are opened on the side wall of the wall panel 23 located within the enclosed space 5. The table panel 24 is set on the side wall of the wall panel 23 with the first suction holes 25 and is provided with a second low-pressure chamber 27 in communication with the first low-pressure chamber 30. The top surface of the table panel 24 is provided with a plurality of second suction holes 26 in communication with the second low-pressure chamber 27. When the exhaust system 2 is in operation, the first low-pressure chamber 30 and the second low-pressure chamber 27 form a negative pressure, and the gas in the enclosed space 5 enters the first low-pressure chamber 30 and the second low-pressure chamber 27 respectively through the first suction holes 25 and the second suction holes 26, and is then discharged by the exhaust system 2, thereby achieving efficient collection of the gas in the enclosed space 5.

[0031] Specifically, first suction holes 25 are provided on the sidewalls of the wall panel 23 above and below the table top 24, allowing the wall panel 23 to absorb air both above and below the table top 24. This structure expands the suction range of the wall panel 23, collecting air at different heights around the table top 24 and reducing air retention near the table top 24. Together with the second suction holes 26 on the table top 24, this creates a suction area surrounding the table top 24, further improving suction efficiency.

[0032] like Figure 2As shown, the exhaust system 2 includes an exhaust duct 22. One end of the exhaust duct 22 is located within the enclosed space 5 and communicates with the first low-pressure chamber 30 on the wall panel 23. The other end is located outside the enclosed space 5 and is provided with an adsorption box 29. Adsorption filler 28 is fixed in the adsorption box 29, and an exhaust fan 21 is fixed to the side wall. When the exhaust fan 21 is in operation, the gas in the enclosed space 5 is drawn into the adsorption box 29 through the first low-pressure chamber 30 and the exhaust duct 22. As the gas passes through the adsorption filler 28, harmful substances therein are adsorbed, and the purified gas is discharged by the exhaust fan 21. In this structure, the exhaust duct 22 is directly connected to the first low-pressure chamber 30, ensuring that the gas collected by the suction component can quickly enter the exhaust system 2. The provision of the adsorption box 29 purifies the exhaust gas to prevent pollution of the external environment. The exhaust fan 21 provides power for the entire exhaust process, ensuring exhaust efficiency.

[0033] The air intake system 1 includes an air intake duct 13, one end of which is located outside the confined space 5 and is fixed with a regulating box 14, an regulating component 12 and a filter element 16 are provided in the regulating box 14, an air intake fan 11 is provided on the side wall, and the filter element 16 is located between the air intake fan 11 and the regulating component 12; the other end of the air intake duct 13 is located in the confined space 5, and a plurality of air inlets 15 are opened on the side wall of the air intake duct 13 located in the confined space 5.

[0034] When the air intake fan 11 is operating, outside air is drawn into the conditioning box 14. It is first filtered by the filter element 16 to remove impurities, and then the temperature and humidity are adjusted by the conditioning assembly 12. The treated air is then delivered into the enclosed space 5 through the air intake pipe 13 and air inlet 15. The provision of the filter element 16 ensures the cleanliness of the air entering the enclosed space 5. The conditioning assembly 12 can adjust the air temperature and humidity according to demand. The air intake fan 11 provides power for the air intake process, and the multiple air inlets 15 ensure that air is evenly delivered into the enclosed space 5. They work together with the exhaust system 2 to maintain the air pressure balance within the space.

[0035] The control system 4 includes an inlet temperature sensor 44, an exhaust temperature sensor 43, and a gas concentration sensor 42 electrically connected to a control panel 41. The control panel 41 and the gas concentration sensor 42 are both located within the enclosed space 5. The gas concentration sensor 42 is used to detect the target gas concentration within the enclosed space 5. The inlet temperature sensor 44 is located within the air inlet duct 13 at the air inlet 15 and is used to collect inlet air temperature data. The exhaust temperature sensor 43 is located within the first low-pressure chamber 30 and is used to collect exhaust air temperature data. The gas concentration sensor 42 transmits the detected target gas concentration data to the control panel 41. When the concentration exceeds a set threshold, the control panel 41 controls the air inlet system 1 and the exhaust system 2 to increase operating power. The temperature data collected by the inlet temperature sensor 44 and the exhaust temperature sensor 43 provides a basis for the regulating component 12. The control panel 41 controls the regulating component 12 to adjust the inlet air temperature and humidity based on the difference between the inlet and exhaust air temperatures to maintain a stable temperature within the enclosed space 5.

[0036] The tabletop 24 is bolted to the wall panel 23, with a sealing strip 31 at the joint. A support frame 20, fixed to the bottom of the tabletop 24, is fixed to the wall panel 23 below the tabletop 24. This bolted connection ensures a secure connection between the tabletop 24 and the wall panel 23 and facilitates assembly and disassembly for maintenance. The sealing strip 31 seals the joint, preventing gas leakage and maintaining the negative pressure in the first and second low-pressure chambers 30 and 27. The support frame 20 provides auxiliary support for the tabletop 24, enhancing its load-bearing capacity and stability and preventing damage to the tabletop 24 due to excessive force.

[0037] Several suction components are evenly distributed along the inner wall of the confined space 5. The suction components, air inlet duct 13, and exhaust duct 22 are all made of modified polyvinyl chloride. This even distribution of suction components effectively collects gas from all areas within the confined space 5, preventing localized gas accumulation. Modified polyvinyl chloride is corrosion-resistant, strong, lightweight, and anti-static, making it suitable for environments where chemical gases may be present, such as dry cleaning rooms. This extends the life of the equipment while reducing its overall weight and simplifying installation.

[0038] Filter element 16 is made of cotton fiber, and adsorbent filler 28 is activated carbon. The cotton fiber filter element 16 has excellent air permeability and filtration performance, effectively intercepting particulate matter and other impurities in the air. It is also low-cost and easy to replace. Activated carbon, as adsorbent filler 28, has a rich pore structure and strong adsorption capacity, effectively absorbing harmful components and odors in the exhaust gas, improving the gas purification effect.

[0039] The working process of this embodiment is as follows: the staff turns on the exhaust device through the control panel 41. When turned on, the exhaust fan 21 will start to rotate and draw out the indoor air through the exhaust pipe 22; the air inlet fan 11 will also rotate to transport the outdoor air into the room.

[0040] When the staff is performing cleaning operations on the table top 24, the harmful gases evaporated by the solvent will be sucked into the first low-pressure chamber 30 through the first suction hole 25 on the wall panel 23, and will also be sucked into the second low-pressure chamber 27 through the second suction hole 26 on the table top 24, and then enter the first low-pressure chamber 30 from the second low-pressure chamber 27. The harmful gases entering the first low-pressure chamber 30 will enter the adsorption box 29 along the exhaust pipe 22 under the action of the exhaust fan 21, and then in the process of passing through the adsorption filler 28 in the adsorption box 29, the activated carbon will absorb the odor and some chemicals in the harmful gases. The absorbed gases will be integrated into the outdoor air after passing through the exhaust fan 21.

[0041] During operation, if the volatilization amount of harmful gases exceeds the current exhaust volume of the exhaust system 2, they will accumulate. When the concentration of the accumulated harmful gases is too high, it will be detected by the gas concentration sensor 42, and the collected information will be sent to the control panel 41. The control panel 41 will control the speed of the exhaust fan 21 to increase the exhaust volume to achieve rapid discharge of harmful gases.

[0042] While the exhaust fan 21 is working, the air inlet fan 11 will also start working, sucking outdoor air into the regulating box 14. The air entering the regulating box 14 will first pass through the filter element 16, and the particulate impurities in the air will be filtered through the cotton fiber material. The filtered air will enter the regulating component 12, and the regulating component 12 will adjust the temperature and humidity of the air. When the temperature and humidity of the air are adjusted, it will be transported into the room through the air inlet pipe 13; and the exhaust temperature sensor 43 installed in the first low-pressure chamber 30 will collect the temperature data of the exhaust gas, and the air inlet temperature sensor 44 installed at the air inlet 15 will collect the temperature data of the gas transported to the room, and the indoor temperature can be dynamically adjusted by comparing the two temperature data. If the regulating component 12 adjusts the gas temperature to the set parameters and delivers it to the room, the air inlet temperature sensor 44 will detect that the gas temperature is within the set parameter range. When the temperature of the gas inhaled by the first low-pressure chamber 30 is lower than the set parameter range, it means that the indoor temperature is too low. At this time, the control panel 41 will control the regulating component 12 to increase the temperature, thereby ensuring that the room can be adjusted to the optimal temperature.

[0043] It should be noted that the parameters of the air inlet fan 11 and the exhaust fan 21 in this embodiment are the same, so the air supply volume and the exhaust volume area are equal under the same rotation speed, so that the indoor pressure can be balanced.

[0044] Example 2: Based on Example 1, a separate solenoid valve 34 is provided at the connection between each suction component and the exhaust duct 22. The separate solenoid valve 34 is electrically connected to a control panel 41. An indicator light 33 and a separate switch 32 are fixed to the wall panel 23, and both the indicator light 33 and the separate switch 32 are electrically connected to the separate solenoid valve 34. The separate solenoid valves 34 can be individually controlled via the control panel 41. When a certain area does not require strong exhaust, the separate solenoid valve 34 of the corresponding suction component can be closed to reduce energy consumption. The separate switch 32 is easy to operate manually, and the indicator light 33 can display the operating status of the separate solenoid valve 34, i.e., whether it is open or closed, so that the operator can intuitively understand the operating status of each suction component. In conjunction with the control panel 41, flexible control of the suction components can be achieved.

[0045] The working process of this embodiment: When the number of staff is small, it would be a waste to start the exhaust system 2 as a whole. At this time, separate control is performed by installing a separate control solenoid valve 34 and a separate control switch 32 on each suction component. The staff adjusts the control mode to separate control through the control panel 41, and then turns on the separate control solenoid valve 34 through the separate control switch 32. At the same time, the air intake fan 11 and the exhaust fan 21 will also be started. The staff can adjust the speed of the exhaust fan through the control panel 41 to adjust the suction volume, and the control panel 41 will also adjust the speed of the air intake fan 11 at the same time, so that the air intake volume of the air intake fan 11 is the same as the exhaust volume of the exhaust fan 21 to balance the indoor gas pressure.

[0046] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
