Description

Technical Field

[0001] The utility model belongs to the field of fan coil units, and in particular relates to an energy-saving fan coil unit. Background Art

[0002] A fan coil unit is a device that integrates heating, ventilation and air conditioning functions. It is usually used in commercial buildings, industrial facilities, residences and other places. It is equipped with coils for heat exchange connected to external heating and cooling equipment and fans for air supply. The fresh air from the outside is sent into the fan coil unit through pipes, and the cold fluid or hot fluid in the built-in coil exchanges heat with the sent air to achieve air heating or cooling. The treated air is then transported to various areas of the building through the built-in fan to achieve cooling or heating effects. In order to prevent dust, pollutants, pollen, bacteria and other particles in the air from entering the room, an isolation net is generally installed at the connection between the fresh air supply pipe and the fan coil unit to filter, so as to improve the indoor air quality and keep the environment clean. A blocked or dirty filter will cause air flow to be obstructed, reduce system efficiency and increase energy consumption. Therefore, the isolation net needs to be cleaned regularly to ensure the normal operation of the fan coil unit.

[0003] The existing fan coil unit filter is usually installed by bolting. When the isolation net is disassembled and cleaned regularly, it is necessary to use bolting tools to assist in installation and disassembly. The loading and unloading process is relatively cumbersome, which greatly wastes the manpower cost of disassembly and cleaning.

[0004] Therefore, the filter of the fan coil unit is installed by bolting. When the isolation net is disassembled and cleaned regularly, a bolt tightening tool is needed to assist in installation and disassembly. The loading and unloading process is very cumbersome, which wastes the labor cost of cleaning. Energy-saving fan coil units are developed. The filter of the fan coil unit adopts an installation structure that automatically locks with a spring, which facilitates quick and tool-free disassembly and assembly of the filter, saving the labor cost of disassembly and cleaning the filter. Utility Model Content

[0005] In order to overcome the problem that the existing fan coil unit filter is installed by bolting, when the isolation net is regularly disassembled and cleaned, it is necessary to use bolting tools to assist in the installation, and the process is cumbersome and wastes labor costs during loading and unloading.

[0006] The technical solution of the utility model is: an energy-saving fan coil unit, including a fan coil unit body, a thermal insulation sleeve, a dustproof net assembly, a dustproof net sealing structure, a dustproof net mounting structure, a pull-out unlocking structure, and a sealing cap plug. The fan coil unit body is inlaid with a dustproof net assembly, a dustproof net sealing structure is arranged below the dustproof net assembly, an elastically telescopically locked dustproof net mounting structure is arranged on the side of the dustproof net assembly, a pull-out unlocking structure is arranged at the end of the dustproof net mounting structure, and a sealing cap plug is arranged on the side of the pull-out unlocking structure.

[0007] Preferably, the thermal insulation sleeve layer uses the low thermal conductivity of the polyurethane material to slow down the rate of internal heat loss, thereby insulating the fan coil and reducing the energy consumption required for temperature control. The slot-type design of the dust screen assembly makes it easy to install the dust screen without disassembling the pipeline, thereby simplifying the steps of disassembling and assembling the dust screen. The dust screen sealing structure uses the silicone sealing pad on the sealing eaves to block small gaps through extrusion and deformation after the dust screen is installed, thereby reducing heat loss in the fan coil unit. The dust screen installation structure uses a spring to push the plug post to facilitate rapid locking of the dust screen moved to the installation position. The pull-out unlocking structure quickly pulls out the plug post to unlock through the pull-out button connected to the plug post, which is convenient for the user to quickly disassemble the dust screen frame. The sealing cap plug uses the elasticity of the silicone sleeve layer to facilitate deformation after being inserted into the pull-out opening to block small gaps through extrusion and deformation, thereby reducing heat loss in the fan coil unit.

[0008] Preferably, the outside of the fan coil unit body is wrapped with a thermal insulation layer of a matching shape except for the connecting pipe interface. The thermal insulation layer is made of polyurethane foam. The low thermal conductivity of the thermal insulation layer made of polyurethane foam reduces the heat loss rate inside the fan coil unit body, reduces the energy consumption required for the fan coil unit body to control the internal temperature to be constant, and achieves an energy-saving effect.

[0009] Preferably, the dustproof net assembly includes a dustproof net slot, a dustproof net frame, and a dustproof net body. A dustproof net slot is opened under the fan coil unit body. A dustproof net frame with a matching appearance is slidably connected to the inner side of the dustproof net slot, and the dustproof net body is fixedly connected to the inside of the dustproof net frame. By inserting the dustproof net frame into the inner slot of the dustproof net in a pull-out installation method, the dustproof net can be easily installed without disassembling the pipeline, which simplifies the steps of disassembling and assembling the dustproof net and saves the time of disassembling and assembling the dustproof net.

[0010] Preferably, the dustproof net sealing structure includes a sealing eave and a sealing groove. The sealing eave is fixedly connected to the lower end of the dustproof net frame. A sealing gasket made of elastic silicone is fixedly connected to the upper surface of the sealing eave. A sealing groove matching the sealing eave is opened on the outer periphery of the notch of the dustproof net groove. After the dustproof net is installed, the silicone sealing gasket on the sealing eave is squeezed against each other by the sealing eave and the sealing groove, so that the silicone sealing gasket is deformed to block the tiny gap at the connection, thereby reducing heat loss in the fan coil unit and playing a role of heat preservation, thereby saving energy consumption for temperature control inside the fan coil unit body.

[0011] Preferably, the dustproof net installation structure includes a post placement groove, a locking post, a spring structure, and a locking groove. The inner wall of the dustproof net groove is provided with a post placement groove, and a locking post with a matching shape is slidably connected inside the post placement groove. A spring structure is connected between the post placement groove and the locking post. A locking groove is provided on the side wall of the dustproof net frame at a position corresponding to the post placement groove. The locking post is pushed by the spring structure. When the dustproof net frame reaches a predetermined installation position, the locking post is automatically pushed into the locking groove to quickly lock the dustproof net frame, thereby saving labor costs during the installation of the dustproof net.

[0012] Preferably, the pull-out unlocking structure includes a pull-out opening, a connecting column, and a pull-out button. A pull-out opening is opened through the inside of the column placement groove, and a connecting column is slidably connected in the pull-out opening. One end of the connecting column is fixedly connected to the locking column, and the other end of the connecting column is fixedly connected to the pull-out button. The locking column is pulled out of the locking slot by pulling the pull-out button connected to the connecting column, thereby releasing the lock of the locking column, facilitating quick disassembly of the dustproof net and reducing the labor cost required for disassembly of the dustproof net.

[0013] Preferably, a sealing cap plug that matches the pull-out opening is fixedly connected to the side of the pull-out button, and the sealing cap plug and the outside of the pull-out button are wrapped with a sheath of elastic silicone material. Due to the elasticity of the silicone sheath of the sealing cap plug, after the sealing cap plug is inserted into the pull-out opening, the deformation caused by the extrusion of the side wall of the pull-out opening can be used to block the tiny gaps on the contact surface, thereby reducing heat loss in the fan coil unit and playing a role of heat preservation, thereby saving energy consumption for temperature control inside the fan coil unit body.

[0014] Beneficial effects of the utility model:

[0015] 1. The thermal insulation sleeve uses the low thermal conductivity of polyurethane material to slow down the internal heat loss rate, thereby insulating the fan coil and reducing the energy consumption required for temperature control. The slot-type design of the dust screen component is convenient for installing the dust screen without dismantling the pipeline, simplifying the steps of disassembling and assembling the dust screen. The dust screen sealing structure uses the silicone sealing pad on the sealing eaves to deform through extrusion after the dust screen is installed to block the small gaps, thereby reducing the heat loss in the fan coil unit. The dust screen installation structure uses a spring to push the plug post, which is convenient for quickly locking the dust screen moved to the installation position. The pull-out unlocking structure quickly pulls out the plug post to unlock through the pull-out button connected to the plug post, which is convenient for users to quickly disassemble the dust screen frame. The sealing cap plug uses the elasticity of the silicone sleeve layer to deform through extrusion after being inserted into the pull-out opening to block the small gaps, thereby reducing the heat loss in the fan coil unit.

[0016] 2. The pull-out dust screen makes it easy to replace the dust screen without dismantling the surrounding pipes, saving the labor cost when replacing the dust screen.

[0017] 3. Use the spring to push the locking pin. When the dust screen frame is in the correct installation position, the locking pin is automatically inserted into the locking groove for locking installation, saving the labor cost when installing the dust screen.

[0018] 4. Use the pull button to pull the locking pin, so that the user can control the locking pin from the outside of the fan coil unit to pull it out of the locking slot and unlock it, saving the labor cost when disassembling the dust screen.

[0019] 5. The sealing cap plug and the sealing silicone pad on the sealing eaves are used to block the gap through elastic deformation, slowing down the heat loss inside the coil unit, achieving a heat preservation effect and saving energy consumption for temperature control inside the fan coil unit.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-2 The utility model provides an embodiment: an energy-saving fan coil unit, comprising a fan coil unit body 1, a thermal insulation sleeve 2, a dustproof net assembly 3, a dustproof net sealing structure 4, a dustproof net mounting structure 5, a pull-out unlocking structure 6, and a sealing cap plug 7. The fan coil unit body 1 is inlaid with a dustproof net assembly 3, a dustproof net sealing structure 4 is arranged below the dustproof net assembly 3, a dustproof net mounting structure 5 with elastic telescopic locking is arranged on the side of the dustproof net assembly 3, a pull-out unlocking structure 6 is arranged at the end of the dustproof net mounting structure 5, and a sealing cap plug 7 is arranged on the side of the pull-out unlocking structure 6. By adopting a mounting structure that automatically buckles and locks the filter of the fan coil unit using a spring, it is convenient to quickly disassemble and assemble the filter without tools, saving the labor cost when disassembling and cleaning the filter.

[0029] See also Figure 3 , 46. In the present embodiment, the outside of the fan coil unit body 1 is wrapped with a thermal insulation layer 2 having a matching shape except for the connection pipe interface. The thermal insulation layer 2 is made of polyurethane foam. The dustproof net sealing structure 4 includes a sealing eave 401 and a sealing groove 402. The lower end of the dustproof net frame 302 is fixedly connected to the sealing eave 401, and the upper surface of the sealing eave 401 is fixedly connected to a sealing pad made of elastic silicone. The outer periphery of the notch of the dustproof net groove 301 is provided with a sealing groove 402 matched with the sealing eave 401. The side of the pull-out button 603 is fixedly connected with a sealing cap 7 matched with the pull-out opening 601. The outer sides of the sealing cap 7 and the pull-out button 603 are wrapped with a sleeve layer of elastic silicone. The low thermal conductivity of the thermal insulation layer 2 made of polyurethane foam can reduce the internal heat of the fan coil unit body 1. The heat loss rate of the fan coil unit body 1 is reduced, and the energy consumption required for controlling the internal temperature of the fan coil unit body 1 to be constant is reduced, thereby achieving energy-saving effect. After the dustproof net is installed, the silicone sealing pad on the sealing eaves 401 is squeezed against each other between the sealing eaves 401 and the sealing groove 402, so that the silicone sealing pad is deformed to block the small gap at the connection, thereby reducing the heat loss in the fan coil unit body 1 and playing a role of heat preservation, thereby saving the energy consumption of the internal temperature control of the fan coil unit body 1. Through the elasticity of the silicone material sleeve layer of the sealing cap plug 7, it is convenient to use the extrusion of the side wall of the withdrawal port 601 to deform after the sealing cap plug 7 is inserted into the withdrawal port 601 to block the small gap on the contact surface, thereby reducing the heat loss in the fan coil unit body 1 and playing a role of heat preservation, thereby saving the energy consumption of the internal temperature control of the fan coil unit body 1.

[0030] See also Figure 4-6In this embodiment, the dustproof net assembly 3 includes a dustproof net slot 301, a dustproof net frame 302, and a dustproof net body 303. A dustproof net slot 301 is provided below the fan coil unit body 1. A dustproof net frame 302 having a matching shape is slidably connected to the inner side of the dustproof net slot 301. The dustproof net frame 302 is fixedly connected to the dustproof net body 303. The dustproof net installation structure 5 includes a column placement slot 501, a locking column 502, a spring structure 503, and a locking slot 504. The inner wall of the dustproof net slot 301 is provided with a plug-in column placement slot 501, and a locking plug-in column 502 with a matching shape is slidably connected inside the plug-in column placement slot 501. A spring structure 503 is connected between the plug-in column placement slot 501 and the locking plug-in column 502. A locking slot 504 is provided at a position corresponding to the plug-in column placement slot 501 on the side wall of the dustproof net frame 302. The pull-out unlocking structure 6 includes a pull-out opening 601, a connecting column 602, and a pull-out button 603. The plug-in column placement slot 501 is connected to the inner wall of the dustproof net frame 302. The pull-out opening 601 is provided, and a connecting column 602 is slidably connected in the pull-out opening 601. One end of the connecting column 602 is fixedly connected to the locking column 502, and the other end of the connecting column 602 is fixedly connected to the pull-out button 603. By inserting the dustproof net frame 302 into the inner groove of the dustproof net for pull-out installation, it is convenient to install the dustproof net without disassembling the pipeline, which simplifies the steps of disassembling and assembling the dustproof net and saves the dustproof net disassembly and assembly. The locking column 502 is pushed by the spring structure 503. When the dustproof net frame 302 reaches the predetermined installation position, the locking column 502 is automatically pushed and inserted into the locking groove 504 to quickly lock the dustproof net frame 302, saving the labor cost when installing the dustproof net. The pull-out button 603 connected to the connecting column 602 is used to pull the locking column 502 out of the locking groove 504, thereby releasing the lock of the locking column 502, facilitating the quick disassembly of the dustproof net and reducing the labor cost required for disassembly of the dustproof net.

[0031] When working, first, when the dust screen needs to be disassembled and cleaned, one hand holds the lower end of the sealing eaves 401 at the lower end of the dust screen frame 302 from below, and the other hand pinches the handle of the pull-out button 603 and pulls it outward, so that the pull-out button 603 drives the connecting column 602 to slide outward in the pull-out opening 601, thereby driving the locking plug column 502 to be pulled out from the locking groove 504, so that the locking plug column 502 contracts and compresses the spring structure 503 toward the inside of the plug column placement groove 501. At this time, the dust screen frame 302 that loses its lock slips out of the dust screen groove 301 due to free fall due to gravity and falls into the user's hand. Then the other hand releases the pull-out button 603, so that the locking plug column 502 is automatically pushed back by the spring structure 503, and the dust screen is disassembled;

[0032] After the dust screen is cleaned, the user holds the lower end of the sealing eaves 401 at the lower end of the dust screen frame 302 with one hand, and pinches the handle of the pull button 603 with the other hand and pulls it outward, so that the pull button 603 drives the connecting column 602 to slide outward in the pull opening 601, thereby contracting the compression spring structure 503 with the locking plug 502 toward the inside of the plug slot 501, until the locking plug 502 is completely retracted into the plug slot 501, and then the other hand pushes the sealing eaves 401 upward, so that the dust screen frame 302 moves upward and is inserted into the dust screen slot 301 The sealing eave 401 is completely immersed in the sealing groove 402, so that the silicone sealing pad on the upper surface of the sealing eave 401 is squeezed and deformed to block the small gap on the contact surface. Then, the pull-out button 603 is released, so that the spring structure 503 automatically pushes the locking plug 502 to insert into the locking groove 504, and the installation net is locked. Then, the handle of the pull-out button 603 is pinched to completely insert the sealing cap plug 7 on the side of the pull-out button 603 into the pull-out opening 601, so that the side wall of the pull-out opening 601 squeezes the pull-out button 603 and deforms to block the small gap on the contact surface.

[0033] The fan coil unit body 1 uses the FP-WA model. When the fan coil unit body 1 is running, the low thermal conductivity of the heat insulation sleeve 2 made of polyurethane foam reduces the heat loss rate inside the fan coil unit body 1, and cooperates with the silicone sealing pad connected to the upper end of the sealing eaves 401 and the silicone sleeve around the sealing cap 7 to produce extrusion deformation to block the gap, thereby reducing the heat loss inside the fan coil unit body 1, and jointly reducing the energy consumption required for the fan coil unit body 1 to control the internal temperature to be constant, thereby achieving energy-saving effect.

[0034] Through the above steps, the slot-type design of the dustproof net component 3 is convenient for installing the dustproof net without disassembling the pipeline, simplifying the steps of disassembling and assembling the dustproof net, and the dustproof net installation structure 5 pushes the plug post through the spring, which is convenient for quickly locking the dustproof net moved to the installation position, and the pull-out unlocking structure 6 quickly pulls out the plug post to unlock through the pull-out button 603 connected to the plug post, which is convenient for the user to quickly disassemble the dustproof net frame 302, and solves the problem that the filter net of the existing fan coil unit is installed by bolt screwing. When the isolation net is regularly disassembled and cleaned, it is necessary to use a bolt screwing tool to assist in the installation, and the process is cumbersome and wastes labor costs during loading and unloading.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
