Description

Technical Field

[0001] This utility model belongs to the field of building heating and ventilation equipment technology, and in particular relates to a high-efficiency ventilation device for building heating and ventilation. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a component of buildings. In academic classification, it is officially called heating, gas supply, ventilation, and air conditioning engineering, which includes three aspects: heating, ventilation, and air conditioning. Functionally, it is an indispensable part of future homes. Among them, ventilation devices are of paramount importance in building HVAC. Damage to ventilation devices will prevent effective air exchange between the HVAC system and the outside air, affecting the efficiency of HVAC. Therefore, the ventilation devices in building HVAC cannot be compromised. A search revealed that patent application number 201920940696.4 discloses a general-purpose high-efficiency ventilation device for building heating, comprising a housing, a ventilation cavity at the upper end of the housing, a mounting frame at the upper end of the ventilation cavity, a fixing bracket and an air pump on the lower side wall of the ventilation cavity, an air suction hood at the inlet end of the air pump, an air outlet hood at the outlet end of the air pump, an activated carbon plate and a ventilation plate inside the housing, the activated carbon plate being positioned above the ventilation plate, the ventilation plate being positioned above the air suction hood, L-shaped mounting seats being positioned above the left and right ends of the activated carbon plate, ventilation holes being provided on the ventilation plate, and a safety door being provided outside the housing.

[0003] However, during actual use, the applicant found that the fan in the device was installed in the mounting frame. Due to the lack of an air filtration structure at the fan, it was unable to filter dust, resulting in a large amount of dust covering the fan, which would reduce the service life of the fan. In view of this, we propose a high-efficiency ventilation device for building heating. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A high-efficiency ventilation device for building heating includes a ventilation box 1. A filter plate 4 is fixedly fastened to the bottom of the front end of the ventilation box 1 by an internal hexagonal screw 8. A limit slot 12 is opened at the bottom of the front end of the ventilation box 1. Limiting blocks 41 are symmetrically arranged on the front and rear sides of the filter plate 4, and the limiting blocks 41 are connected to the limit slot 12. One end of the internal hexagonal screw 8 passes through a stepped hole opened on the front side of the ventilation box 1 and is screwed into a threaded hole opened on the filter plate 4. An air intake fan 9 is fixedly installed on the inner wall of the ventilation box 1 near the filter plate 4. A fixing plate 5 is fixedly connected to the bottom of the ventilation box 1 on the rear side of the filter plate 4. An electric push rod 2 is fixedly installed on the rear side of the fixing plate 5. The electric push rod 2 and the air intake fan 9 are connected to the filter plate 4. The fans 9 all utilize existing commercial technology and are controlled by an external controller, so they will not be described in detail here. The telescopic end of the electric push rod 2 moves through the fixed plate 5 and is fixedly connected to the movable frame 6. The top of the movable frame 6 is locked and fixed with the dust cleaning brush frame 7 by the locking bolt 63. The top of the movable frame 6 has a T-shaped mounting groove 62. The lower part of the dust cleaning brush frame 7 is slidably installed in the T-shaped mounting groove 62. The upper end of the locking bolt 63 is screwed into the threaded hole at the bottom of the dust cleaning brush frame 7. The brush on the upper part of the dust cleaning brush frame 7 cleans along the cleaning end face of the filter plate 4. By installing the air intake fan 9 inside the ventilation box 1 and filtering the air entering the ventilation box 1 through the filter plate 4, dust can be prevented from falling. To extend the service life of the low-intake fan 9, the electric push rod 2 drives the moving frame 6 forward, which in turn moves the cleaning brush frame 7 forward. The cleaning brush frame 7 cleans the dust from the bottom filter end face of the filter plate 4, ensuring better ventilation of the filter plate 4. The cleaning brush frame 7 can be removed from the moving frame 6 by unscrewing the locking bolt 63 from its bottom for cleaning. Guide sleeves 3 are symmetrically fixed to the fixing plates 5 on both sides of the electric push rod 2. Guide rods 61 are symmetrically fixed to the rear side of the moving frame 6. The rear end of the guide rods 61 moves through the fixing plates 5 and slides along the guide sleeves 3. During use, the air intake fan 9 can be driven to rotate, allowing... Outside air enters the ventilation box 1 after being filtered by the filter plate 4, and is then guided to the building's HVAC ventilation ducts through the ventilation box 1. The moving frame 6, along with the dust removal brush frame 7, can be moved forward at regular intervals by driving the electric push rod 2. The dust removal brush frame 7 cleans the dust on the bottom filter end face of the filter plate 4, ensuring that the filter plate 4 can maintain efficient ventilation. When it is necessary to disassemble and clean the filter plate 4 and the dust removal brush frame 7, the filter plate 4 can be slid out of the limiting slot 12 by unscrewing the hexagonal screw 8 from the filter plate 4. The dust removal brush frame 7 can be slid out of the T-shaped mounting slot 62 by unscrewing the locking bolt 63 from the bottom of the dust removal brush frame 7, allowing for disassembly and cleaning.

[0022] A protrusion 11 is fixedly installed on the top of the ventilation box 1 above the inlet fan 9. An outlet air duct 111 is opened in the protrusion 11. An outlet fan 10 is fixedly installed on the inner wall of the front end of the outlet air duct 111. The outlet fan 10 is a commercially available technology and is controlled by an external controller, so it will not be described in detail here. The outlet fan 10 is located directly above the filter plate 4. The rear end of the protrusion 11 is located behind the inlet fan 9, and the outlet air duct 111 communicates with the interior of the ventilation box 1. The dust removal brush holder 7... During the cleaning process of filter plate 4, by turning off the inlet fan 9 and turning on the outlet fan 10, air can be blown towards filter plate 4 to blow away the dust swept off filter plate 4, which can further improve the dust removal effect of filter plate 4. During the dust removal process of filter plate 4 by dust removal brush frame 7, the inlet fan 9 can be turned off and the outlet fan 10 can be turned on. At this time, the outlet fan 10 rotates and blows air towards filter plate 4, blowing away the dust swept off filter plate 4, which improves the dust removal effect of filter plate 4.

[0023] Working principle: During use, the intake fan 9 is driven to rotate, allowing outside air to pass through the filter plate 4 and enter the ventilation box 1. The air is then guided through the ventilation box 1 to the building's HVAC ductwork. The electric push rod 2 can be driven periodically to move the movable frame 6, along with the cleaning brush frame 7, forward. The cleaning brush frame 7 cleans the dust on the bottom filter surface of the filter plate 4, ensuring efficient ventilation. During the cleaning process, the intake fan 9 can be turned off and the exhaust fan 10 can be turned on. At this time, the blower 10 rotates and blows air toward the filter plate 4, blowing away the dust swept off the filter plate 4 and improving the dust removal effect of the filter plate 4. When it is necessary to disassemble and clean the filter plate 4 and the dust removal brush holder 7, the filter plate 4 can be slid out of the limit slot 12 by unscrewing the internal hexagonal screw 8 from the filter plate 4. The dust removal brush holder 7 can be slid out of the T-shaped mounting slot 62 by unscrewing the locking bolt 63 from the bottom of the dust removal brush holder 7, and the dust removal brush holder 7 can be disassembled and cleaned.
