DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0053] In the description of the embodiments of this application, 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 a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0054] In the description of the embodiments of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application 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 a limitation on the present application.

[0055] In the description of the embodiments of the present application, “plurality” means two or more, unless otherwise precisely and specifically specified.

[0056] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0057] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0058] As mentioned in the background technology, currently, there are many electrical devices in the SVG room, which generate a lot of heat when working. In the existing technology, fans are added to the ventilation ducts to draw outdoor air into the room to dissipate heat in the SVG room.

[0059] However, in some application scenarios, such as when the SVG room is set up in a relatively harsh environment or encounters rainy or snowy weather, a large amount of water vapor in the air enters the SVG room through the ventilation ducts. Even impurities such as dust and dust in the environment enter the SVG room. The dust and water vapor adhere to the electrical equipment, causing corrosion and aging of the electrical equipment, affecting the operation of the electrical equipment.

[0060] High humidity levels in SVG rooms can directly or indirectly cause electrical equipment to short-circuit, leading to tripping. Excessive dust can also cause false alarms in SVG smoke detectors. Extensive monitoring data shows that, for example, during the autumn and winter months, when the average daily humidity is 85%, the smoke detectors experience 57 false alarms and an average annual trip rate of 4. Consequently, SVG rooms frequently trip due to high dust flow, frequent false smoke alarms, high average humidity levels in autumn and winter, and high electrical equipment failure rates, posing a serious threat to the safe and stable operation of the SVG rooms.

[0061] Based on the above technical problems, the present invention provides a ventilation structure for installation on a ventilation duct connecting the indoor and outdoor spaces of an SVG. The structure comprises a mounting assembly, a dust filter assembly, a fan assembly, and a dehumidification mechanism. The fan assembly draws outdoor air into the room. During this process, the dust filter assembly first filters the air, removing dust from the air. The dehumidification mechanism includes an air deflector and a condensation assembly, with the air deflector disposed between the condensation assembly and the fan assembly. A portion of the condensation assembly is configured to come into contact with the air and condense water vapor into water droplets.

[0062] In this way, air filtered by the dust filter is guided by the air guide plate and then comes into contact with the condensation assembly. Water vapor in the air condenses into water droplets on the condensation assembly, thereby dehumidifying the air entering the room. This not only purifies the air entering the SVG room but also dehumidifies it, increasing air dryness and reducing humidity inside the SVG room, thus ensuring the normal operation of the SVG's electrical equipment. With this setup, the humidity inside the SVG room can be reduced to 63%, reducing the number of false smoke alarms caused by excessive dust and high humidity to zero, and the number of annual trips to zero.

[0063] Compared with the traditional setting method, the ventilation structure provided in the embodiment of the present application can reduce the failure rate of electrical equipment in the SVG room and ensure the normal operation of the SVG room.

[0064] It should be noted that in this technical solution, the ventilation duct can be any ventilation duct in any house, building, facility, etc., and can be a channel opened in the wall or a pipe made of different materials that runs through the wall. Its main function is to connect the indoor and outdoor spaces to achieve air circulation. The specific structure of the ventilation duct is not limited in this embodiment of the application. This embodiment of the application only uses the SVG room as an example for description.

[0065] It should be noted that Figures 1 to 4 The schematic diagram of each component in the ventilation structure is shown. The specific structure of the remaining components in the ventilation structure is not limited to Figures 1 to 4 of examples.

[0066] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0067] Reference Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides a ventilation structure for installation on a ventilation duct for indoor ventilation, including a mounting member 100, a dust filter assembly 200, a fan assembly 300 and a dehumidification mechanism 400.

[0068] The mounting member 100 is used to be inserted into the ventilation duct. Specifically, the outer wall of the mounting member 100 is set to a shape that matches the inner wall of the ventilation duct to facilitate the installation of the mounting member 100. In order to improve the stability of the mounting member 100, the mounting member 100 and the ventilation duct can be an interference fit.

[0069] The mounting member 100 has a ventilation cavity 110 therein, and the dust filter assembly 200 is connected to the mounting member 100 . The dust filter assembly 200 is used to filter the air entering the ventilation cavity 110 .

[0070] The dehumidification mechanism 400 includes an air guide plate 410 and a condensing assembly 420 .

[0071] In order to improve space utilization, the fan assembly 300 , the air guide plate 410 and the partial condensation assembly 420 are all arranged in the ventilation cavity 110 .

[0072] The fan assembly 300 is disposed between the dust filter assembly 200 and the air guide plate 410 , and the air guide plate 410 is disposed between the condensation assembly 420 and the fan assembly 300 .

[0073] Of course, the fan assembly 300 can also be arranged in the ventilation duct, as long as the fan assembly 300 can provide suction force to draw outdoor air into the room.

[0074] The partial condensing component 420 is used to contact with the air and condense the water vapor in the air into water droplets.

[0075] The fan assembly 300 is configured to draw outdoor air into the ventilation cavity 110 so that the air is filtered by the dust filter assembly 200 and then enters the room after contacting a portion of the condensation assembly 420 through the air guide plate 410.

[0076] In the above embodiment, outdoor air, under the action of the suction force provided by the fan assembly 300, first passes through the filtering action of the dust filter assembly 200 to remove dust and other impurities in the air, and then contacts the air guide plate 410. Under the guidance of the air guide plate 410, the air is blown to the partial condensation assembly 420, condenses into water droplets on the partial condensation assembly 420, and is finally blown into the room. In this way, the dust and water vapor in the air entering the room are filtered out compared to the outdoor air. While improving the air purification level in the SVG room and making the SVG room clean, it can also reduce the air humidity in the SVG room, thereby reducing the corrosion damage of electrical equipment in the SVG room due to high air humidity.

[0077] In a possible implementation, the condensation assembly 420 includes a condensation plate 421 and a Peltier effect module 422 .

[0078] The condensation plate 421 is arranged in the ventilation cavity 110, and the Peltier effect module 422 has a cold end and a hot end. The temperature of the cold end is lower than that of the hot end. The cold end of the Peltier effect module 422 abuts against and is electrically connected to the condensation plate 421 to reduce the temperature of the condensation plate 421.

[0079] The hot end of the Peltier effect module 422 is arranged outdoors to dissipate heat for a portion of the Peltier effect module 422 .

[0080] In specific implementation, the Peltier effect module 422 is a closed loop composed of two different metals based on the Peltier effect. When a DC power supply 4221 is present in the loop, a temperature difference will be generated between the joints of the two different metals. At this time, the position with lower temperature is connected to the condensation plate 421, which can reduce the temperature of the condensation plate 421 and thereby achieve condensation of water vapor in the air.

[0081] In one possible implementation, refer to Figure 1 、 Figure 3 and Figure 4 As shown, the Peltier effect module 422 includes a DC power supply 4221 , a first conductor 4222 , a second conductor 4223 , a first heating plate 4224 and a second heating plate 4225 .

[0082] The first conductor 4222 and the second conductor 4223 are made of different materials. The first conductor 4222 and the second conductor 4223 have a cold end and a hot end respectively. The cold end of the first conductor 4222 and the cold end of the second conductor 4223 are both in contact with and electrically connected to the condensation plate 421 .

[0083] The first heating plate 4224 and the second heating plate 4225 are respectively in contact with and electrically connected to the hot end of the first conductor 4222 and the hot end of the second conductor 4223 .

[0084] The DC power supply 4221 , the first heating plate 4224 , the first conductor 4222 , the condensing plate 421 , the second conductor 4223 and the second heating plate 4225 form a closed loop.

[0085] The first heating plate 4224 and the second heating plate 4225 are both arranged outdoors.

[0086] In the above embodiment, the DC power supply 4221, the first heating plate 4224, the first conductor 4222, the condenser plate 421, the second conductor 4223, and the second heating plate 4225 form a closed circuit. Due to the Peltier effect, the temperatures of the first and second heating plates 4224 and 4225 increase, while the temperature of the condenser plate 421 decreases. Both the first and second heating plates 4224 and 4225 are located outdoors, which facilitates heat dissipation for the first and second heating plates 4224 and 4225. It should be noted that the first and second conductors 4222 and 4223 are related technologies in this field. Simply by ensuring that the first and second conductors 4222 and 4223 are made of different materials, the condenser plate 421 can maintain a low temperature due to the Peltier effect. This application does not limit the specific structures of the first and second conductors 4222 and 4223. Of course, since water droplets condense on the condenser plate 421, which also serves as a conductor, the surface of the condenser plate 421 where water droplets can condense is coated with an insulating coating to prevent short circuits.

[0087] In one possible embodiment, the dehumidification mechanism 400 further includes an air guide plate 410. A vent 4211 is defined on the condensation plate 421. The projection of the vent 4211 toward the air guide plate 410 is located within the air guide plate 410. A gap is provided between the air guide plate 410 and the inner wall of the ventilation cavity, allowing air to pass through the gap and enter the vent 4211. In this way, all air in the ventilation cavity 110 must contact the condensation plate 421 before being discharged into the room through the vent 4211 on the condensation plate 421. This helps improve the condensation efficiency of water vapor in the air and allows more water vapor to condense.

[0088] Of course, when the condensed water droplets reach a certain amount, they need to be discharged in time. For this purpose, at least one water guide groove 4212 and a water collecting groove 4213 connected to the water guide groove 4212 are provided on the condensation plate 421 .

[0089] A drainage channel 120 is defined in the mounting member 100 , and the drainage channel 120 connects the ventilation cavity 110 and the outside.

[0090] The water collecting groove 4213 is connected to the drainage channel 120 so that the water droplets condensed on the condensation plate 421 are discharged to the outside through the water guide groove 4212, the water collecting groove 4213 and the drainage channel 120.

[0091] In the above embodiment, water droplets condensed on condensation plate 421 are guided by water guide grooves 4212 and flow into water collection grooves 4213. Water collection grooves 4213 are connected to drainage channel 120 and are then discharged to the outside through drainage channel 120. Water guide grooves 4212 are arranged in an annular shape, and multiple water guide grooves 4212 are spaced apart to help improve the flow of water on condensation plate 421. Water collection grooves 4213 are located at the bottom of condensation plate 421 and communicate with drainage channel 120, allowing water on condensation plate 421 to flow into water collection grooves 4213 under its own gravity.

[0092] In a specific implementation, in order to prevent the water droplets condensed on the condensation plate 421 from dripping into the ventilation cavity 110 , a water retaining strip 423 is provided around the condensation plate 421 to prevent the water droplets from falling from the condensation plate 421 into the ventilation cavity 110 .

[0093] In a possible implementation, the dust filter assembly 200 includes a filter frame 210 , a filter element 220 , and a plurality of air guide strips 230 .

[0094] The filter frame 210 is connected to the mounting member 100 .

[0095] The filter frame 210 has an installation cavity communicated with the ventilation cavity 110 , and the filter element 220 is disposed in the installation cavity and faces one side of the ventilation cavity 110 to filter air.

[0096] The air guide strips 230 are connected to two opposite inner side walls of the installation cavity.

[0097] In the above embodiment, outdoor air first comes into contact with the air guide strips 230. These strips reduce the air's velocity and guide it, effectively filtering out dust from the air. Specifically, the cross-section of the air guide strips 230 is S-shaped. This S-shaped strip effectively reduces the air's velocity and guides it, reducing the velocity of the air entering the room and effectively filtering out dust and moisture from the air.

[0098] In one possible embodiment, the filter element 220 is filter cotton, which can effectively filter fine particles such as dust and smoke in the air. The filter cotton can be integrated with the air guide strip 230, or it can be set on the side of the installation cavity facing the ventilation cavity 110. If it is set on the side of the installation cavity facing the ventilation cavity 110, in order to improve the stability of the filter cotton, a wire mesh (not shown in the figure) is also provided on the filter frame 210 to clamp the filter cotton between the wire mesh and the filter frame 210, and it can also facilitate the disassembly and replacement of the filter cotton.

[0099] In a possible embodiment, the filter frame 210 further has a plurality of mounting portions 240 , and the end of the mounting member 100 facing the outside has a flange 130 .

[0100] The filter frame 210 is detachably connected to the flange 130 via the mounting portion 240 .

[0101] In this way, the filter frame 210 is detachably connected to the mounting member 100 . When the dust filter assembly 200 needs to be repaired or the filter element 220 is replaced after working for a period of time, the filter frame 210 can be conveniently removed through the mounting portion 240 .

[0102] In addition, the end of the mounting member 100 facing the outdoors has a flange 130. It can be understood that the flange 130 is arranged on the outer peripheral side of the ventilation duct and also has a sealing and dust-proof effect, thereby improving the airtightness between the ventilation duct and the mounting member 100.

[0103] In one possible implementation, the fan assembly 300 includes a driving member 310 , a transmission member 320 , a mounting frame 330 , a mounting shaft 340 , and a plurality of blades 350 .

[0104] The mounting frame 330 is disposed in the ventilation cavity 110 , the mounting shaft 340 is rotatably connected to the mounting frame 330 , the blade 350 is connected to the mounting shaft 340 , and the transmission member 320 connects the driving member 310 and the mounting shaft 340 .

[0105] The driving member 310 is connected to the mounting member 100 . The driving member 310 is configured to drive the mounting shaft 340 to rotate via the transmission member 320 , thereby driving the blades 350 to rotate.

[0106] Here, the driving member 310 drives the installation shaft 340 to rotate through the transmission member 320, and the installation shaft 340 drives each blade 350 to rotate, thereby providing suction force to the air, and driving the air flow through the rotation of the blade 350. This structure is relatively simple, helps to reduce costs, and this mechanism is easy to install.

[0107] In addition, the transmission member 320 includes a first pulley 321 , a second pulley 322 and a transmission belt 323 .

[0108] One of the first pulley 321 and the second pulley 322 is connected to the driving member 310, and the other is sleeved on the mounting shaft 340. The first pulley 321 and the second pulley 322 are connected by a transmission belt 323. In the drawings, the first pulley 321 is connected to the driving member 310, and the second pulley 322 is sleeved on the mounting shaft 340.

[0109] Here, belt transmission is achieved by setting a transmission belt 323, which has a simple structure, low cost, and easy installation. It has overload protection, improves safety, is easy to maintain, operates stably, and also has the effect of saving space.

[0110] It should be noted that the first pulley 321 and the second pulley 322 here are related technologies in this field, and their specific structures are not limited here.

[0111] In one possible embodiment, the driving member 310 is an electric motor, and its rotation speed is selected to be 350r / min to 450r / min. The motor can be set in the ventilation cavity 110 or on the mounting member 100. The embodiment of the present application does not limit the setting position of the motor.

[0112] The implementation principle of a ventilation structure in an embodiment of the present application is as follows: a ventilation structure is set in the ventilation duct of the SVG room, including a mounting member 100, a dust filter assembly 200, a fan assembly 300 and a dehumidification mechanism 400. The mounting member 100 is used to be inserted into the ventilation duct, and the mounting member 100 has a ventilation cavity 110 inside. The dust filter assembly 200 is connected to the mounting member 100, and the dust filter assembly 200 is used to filter the air entering the ventilation cavity 110. The dehumidification mechanism 400 includes an air guide plate 410 and a condensation assembly 420. The fan assembly 300, the air guide plate 410 and the partial condensation assembly 420 are all set in the ventilation cavity 110. The fan assembly 300 is set between the dust filter assembly 200 and the air guide plate 410, and the air guide plate 410 is set between the condensation assembly 420 and the fan assembly 300. The partial condensation assembly 420 is used to contact with the air and condense the water vapor in the air into water droplets. The fan assembly 300 is configured to draw outdoor air into the ventilation chamber 110, so that after being filtered by the dust filter assembly 200, the air passes through the air guide plate 410 and contacts the partial condensation assembly 420 before entering the room. Thus, under the suction force provided by the fan assembly 300, the outdoor air is first filtered by the dust filter assembly 200, removing dust and other impurities from the air. The air then contacts the air guide plate 410 and is guided by the air guide plate 410 to the partial condensation assembly 420, where it condenses into water droplets before finally being blown into the room. Thus, the air entering the room is more dust- and water-repellent than the outdoor air, improving the air purification level and cleanliness of the SVG room while also reducing the air humidity inside the SVG room, thereby reducing corrosion and damage to electrical equipment inside the SVG room caused by high air humidity.
