Description

Technical Field

[0001] The present invention belongs to the technical field of air source heat pumps, and in particular relates to an air source heat pump intake pipe structure and an air source heat pump. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to transfer heat from a low-level heat source to a high-level heat source. It can convert low-level heat energy that cannot be directly utilized into usable high-level heat energy, thereby saving some of the high-level energy. However, during the fresh air purification process of the air source heat pump, a large amount of dust will accumulate on the walls of the air inlet duct due to long-term use of the duct, thus affecting the fresh air purification effect of the air source heat pump. The long-term accumulated dust is also easy to fall off, clogging the filter or affecting the internal structure of the equipment. Therefore, it is necessary to improve the air inlet duct used for fresh air purification of the air source heat pump.

[0003] A Chinese patent with application number 201910510657.5 disclosed an air source heat pump intake pipe structure that is convenient for dust removal, including a pipe body; a rectangular groove and a screw groove are provided at the bottom of the inner wall of the pipe body; a rectangular hole is provided on the bottom surface of the rectangular groove; a screw is rotatably connected in the screw groove; the pipe body is connected to a dust removal ring through the screw; the interior of the dust removal ring is a hollow structure; an annular groove is provided on the circumferential side of the dust removal ring, and an annular scraper is provided inside; a dust collecting pipe matching the rectangular groove is fixedly connected to the circumferential side of the dust removal ring. The present invention solves the problem that dust easily accumulates on the inner wall of the air intake pipe of the existing air source heat pump, affecting the use of the equipment, by arranging a dust removal ring in the pipe body and using the annular scraper on the dust removal ring to clean the inner wall of the pipe body, thereby improving the reliability of the equipment; at the same time, the collected dust is discharged from the air intake pipe through the rectangular hole, so that the air intake pipe can be cleaned without stopping the air source heat pump, thereby improving the use efficiency of the equipment; although the above-mentioned device can clean the dust on the inner wall of the air intake pipe, the above-mentioned device cannot dredge the clogged filter holes, and there is also a situation where the filter holes are clogged and affect the normal operation of the air source heat pump. Therefore, the present application designs an air source heat pump air intake pipe structure. Summary of the Invention

The movement of the fixed frame drives the first pivot arm and the second pivot arm to rotate in the opposite direction until the ends of the first pivot arm and the second pivot arm contact the inner angle of the fixed groove, limiting the rotation of the first pivot arm and the second pivot arm. It also serves the purpose of limiting the locking plate to prevent the locking plate from moving, and finally fixing the filter barrel in the intake pipe.

When the air enters the intake pipe from the through hole, the fan blades can be driven to rotate, and the rotation of the fan blades drives the rotating shaft to rotate. The rotation of the rotating shaft drives the rotating rod to rotate, and the rotation of the rotating rod drives the scraper to rotate. During the operation of the air source heat pump, the scraper continuously scrapes the inner wall of the filter barrel, thereby ensuring the cleanliness of the inner wall of the filter barrel and reducing the risk of impurities in the air clogging the filter holes.

[0015] An air source heat pump includes the air inlet pipe structure shown above.

[0016] The beneficial effects of the present invention are: 1) This device can not only scrape away impurities on the inner wall of the intake pipe, but also dredge the clogged filter holes under the action of the dredging component. The driving member is used to drive the crankshaft to rotate. The rotation of the crankshaft can drive the first movable ring and the second movable ring to move toward the middle at the same time. In the process of the first movable ring and the second movable ring moving toward the middle, the air in the space formed by the first movable ring, the second movable ring and the installation cavity will be compressed, forcing the compressed air to be discharged from the filter holes on the filter component, thereby dredging the clogged filter holes.

[0017] 2) The filter assembly of this device can filter out impurities in the air, preventing impurities from entering the interior of the air source heat pump and causing damage to the internal components of the air source heat pump, thereby increasing the service life of the air source heat pump.

[0019] 4) The locking member of the device is used to fix the filter assembly to the inside of the installation cavity and the air inlet pipe, and can ensure that the filter assembly is always in a stable state during operation. Since the fixing plate is fixedly installed on the side wall of the guide hole, the locking plate is inserted into the positioning hole, and the fixing cylinder is rotated to drive the locking plate to rotate in the guide hole until the fixing plate enters the fixing groove from the through hole. Continuing to rotate the fixing cylinder will compress the first rotating arm and the second rotating arm, so that the first rotating arm and the second rotating arm rotate around the hinge of the first rotating arm and the second rotating arm. When the first and second rotating arms are in the fixed groove, the second spring resets and drives the sliding frame to move toward the side close to the fixed plate. The movement of the fixed frame drives the first rotating arm and the second rotating arm to rotate in the opposite direction until the ends of the first and second rotating arms contact the inner angles of the fixed groove, limiting the rotation of the first and second rotating arms, and also serving the purpose of limiting the locking plate to prevent the locking plate from moving, and finally fixing the filter barrel in the intake pipe.

[0020] 5) The setting of the limiting column of this device increases the contact area between the first rotating arm, the second rotating arm and the inner wall of the fixed groove on the locking plate, ensuring the normal operation of the first rotating arm and the second rotating arm. The setting of the movable plate and the third spring can ensure that the limiting columns on the first rotating arm and the second rotating arm are always located at the inner corner of the fixed groove, preventing the first rotating arm and the second rotating arm from sliding out of the through hole due to vibration during operation, thereby ensuring the normal operation of the filter barrel.

[0021] 6) The setting of the sliding frame of the device can drive the first rotating arm and the second rotating arm to rotate, thereby releasing the restriction of the first rotating arm and the second rotating arm on the locking plate, and ensuring the normal unlocking of the locking member.

[0022] 7) The setting of the sliding hole of this device can serve the purpose of guiding the sliding plate on the one hand, and on the other hand, it can also serve the purpose of limiting the sliding plate, preventing the limit plate from moving a large distance and detaching from the guide rod, thereby ensuring the normal operation of the sliding plate. The setting of the pushing block facilitates the movement of the sliding plate.

[0023] 8) The setting of the scraper assembly of this device can scrape off impurities on the inner wall of the filter barrel, reduce the risk of impurities in the air clogging the through holes, and ensure the normal operation of the filter barrel. When air enters the air inlet pipe from the through hole, it can drive the fan blades to rotate, and the rotation of the fan blades drives the rotation of the rotating shaft, and the rotation of the rotating shaft drives the rotation of the rotating rod, and the rotation of the rotating rod drives the scraper to rotate. During the operation of the air source heat pump, the scraper continuously scrapes the inner wall of the filter barrel, ensuring the cleanliness of the inner wall of the filter barrel and reducing the risk of impurities in the air clogging the filter holes.

[0024] 9) The setting of the rubber pad of this device can prevent the gas from flowing out from the first movable ring, the second movable ring, the filter barrel and the inner wall of the installation cavity respectively, ensuring that the compressed gas can dredge the filter holes, thereby improving the dredging efficiency. The setting of the guide block and the guide groove can, on the one hand, guide the first movable ring and the second movable ring, and on the other hand, prevent the first movable ring and the second movable ring from shaking, thereby ensuring the normal operation of the first movable ring and the second movable ring.

[0025] 10) The setting of the fixed shell of this device can protect the dredging component and also facilitate the installation of the device. The driving member can drive the crankshaft to rotate. The rotation of the crankshaft drives the first push-pull rod and the second push-pull rod, and at the same time drives the first movable ring and the second movable ring to move, ensuring that the dredging component can dredge the clogged filter holes, thereby ensuring the normal operation of the device.

[0046] In this embodiment, Figure 2 As shown, a plurality of first springs 102 distributed in a circle are also provided on the step 101.
