Description

Technical Field

[0001] The utility model relates to the field of air source heat pumps, in particular to an air source heat pump for heating and cooling. Background Art

[0002] According to the second law of thermodynamics, heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but work must be done to transfer heat from a low-temperature object to a high-temperature object. The heat pump system realizes the transfer of energy from a low-temperature object to a high-temperature object. It obtains energy from the natural environment at the cost of spending a part of high-quality energy (electricity), and supplies heat to users together with the spent high-quality energy.

[0003] During the use of the ultra-low temperature air source heat pump, water needs to continuously enter the ultra-low temperature air source heat pump. After searching, the Chinese patent announcement number: CN220250374U discloses an air source heat pump water filter device, which relates to the field of water filtering technology, including an air source heat pump body, the air source heat pump body includes a mounting box seat, and a water filter assembly is arranged on the outer side of the mounting box seat. The water filter assembly includes a Z-type connecting pipe, and a water quality filter component is installed in the middle of the Z-type connecting pipe. The scheme can connect and fix the Z-type connecting pipe between the metal box and the water delivery pipe through the connecting flanges respectively installed at both ends of the Z-type connecting pipe. When the water is introduced into the interior of the metal box through the Z-type connecting pipe, the particulate impurities in the water can be filtered through the filter element installed between the first connecting tube and the second connecting tube, which can prevent the particulate impurities in the water from entering the interior of the metal box and causing the water delivery branch pipe to be blocked, and can ensure the smooth operation of the air source heat pump, thereby reducing the possibility of damage to the air source heat pump due to blockage of the water delivery branch pipe.

[0004] The above-mentioned prior art solutions have the following defects. In the above-mentioned technical solution, when filtering water during the use of the air source heat pump, since the air source heat pump needs to continuously filter the water during continuous operation, this method used to filter the water of the air source heat pump requires frequent replacement of the filter element. However, since the filter element is fixed in two connecting tubes with a flange and multiple bolts in the above-mentioned technical solution, it is inconvenient to replace the filter element during water filtration in the air source heat pump. It is inconvenient to take out the filter element for quick replacement while the air source heat pump is running to maintain the continuous operation of the air source heat pump. In addition, it is inconvenient to take out the dust removal mesh plate inside the connecting screw ring, and the connecting screw ring needs to be rotated multiple times to be taken out for cleaning. Therefore, an air source heat pump for heating and cooling is proposed to solve the above problems. Utility Model Content

The top of the multi-way connecting pipe 5 is threadedly connected with a fixing sleeve 6, which can support the upper opening plate 7, and the upper opening plate 7 is arranged inside the fixing sleeve 6. The bottom of the multi-way connecting pipe 4 is threadedly connected with a fixing sleeve 8, which can support the lower opening plate 9, and the lower opening plate 9 is arranged inside the fixing sleeve 8. The lower opening plate 9 can seal the interior of the fixing sleeve 8, so that after the new filter element 13 enters the multi-way connecting pipe 4 from the inside, it is not easy for the water flow to impact and open the bottom of the fixing sleeve 8. The front and back sides of the opening plate 7 and the lower opening plate 9 are fixedly connected with a fixing rod 10, and the fixing rod 10 can make the lower opening plate 9 and the upper opening plate 7 as the center for rotation. The inner walls of the fixing sleeve 1 6 and the fixing sleeve 2 8 are provided with a receiving opening 11, and the receiving opening 11 can receive the fixing rod 10. The fixing rod 10 is movably connected inside the receiving opening 11.

[0035] Reference Figure 3-5 The sealing assembly includes a sealing gasket 14, the number of which is four. The four sealing gaskets 14 are fixedly connected to the bottom of the upper opening plate 7 and the top of the lower opening plate 9 respectively. The sealing gasket 14 can ensure the sealing between the upper opening plate 7 and the lower opening plate 9 and the multi-way connecting pipe 2 5 and the multi-way connecting pipe 1 4 respectively, so that the water inside the multi-way connecting pipe 1 4 and the multi-way connecting pipe 2 5 overflows from between the upper opening plate 7 and the lower opening plate 9; the limiting assembly includes a limiting ring 15, which is located on the outer side of the filter element 13, and the limiting ring 15 can ensure the sealing between the rubber The rubber ring 16 is used for support; the inner wall of the limiting ring 15 is fixedly connected with a rubber ring 16, which can limit the filter element 13 inside the multi-way connecting tube 1 4 and the multi-way connecting tube 2 5, so that the filter element 13 is stably placed inside the multi-way connecting tube 1 4 and the multi-way connecting tube 2 5 to filter the water body, and the inner side of the rubber ring 16 is in contact with the outer side of the filter element 13; the top of the fixed sleeve 6 is threadedly connected with a sealing cover 17, and the sealing cover 17 is located on the top of the upper opening plate 7, and the sealing cover 17 can reinforce and seal the top of the fixed sleeve 6.

[0036] Working principle: After the user starts the air source heat pump body 1 and allows the water to flow through the multi-way connecting pipe 1 4 and the multi-way connecting pipe 2 5, the impurities in the water are filtered by the filter core 13 inside the multi-way connecting pipe 1 4 and the multi-way connecting pipe 2 5 to prevent the impurities from entering the interior of the air source heat pump body 1. When the air source heat pump body 1 is in use, when it is necessary to take out the filter core 13 from between the multi-way connecting pipe 1 4 and the multi-way connecting pipe 2 5 for replacement, first insert the new filter core 13 from the bottom of the fixed sleeve 2 8 through the top of the lower open plate 9 into the interior of the fixed sleeve 2 8, so that the lower open plate 9 drives the fixing rod 10 in the fixed sleeve 2. After the receiving opening 11 of the inner wall of the sleeve is rotated, and the fixing rod 10 rotates to elastically twist the torsion spring 12 inside the fixing sleeve 8, the lower opening plate 9 continues to clamp the filter element 13, so that the top of the filter element 13 passes through the limiting ring 15 and the rubber ring 16 at the top of the fixing sleeve 8 and contacts the old filter element 13 in the multi-way connecting pipe 4, and after the old filter element 13 is lifted up, the sealing cover 17 is rotated to open the top of the fixing sleeve 6, so that the old filter element 13 contacts the bottom of the upper opening plate 7, and then the upper opening plate 7 is pushed around the fixing rod 10 at the receiving opening 11. The internal rotation twists the torsion spring 12, and after the upper opening plate 7 flips upward, the old filter element 13 moves up and is removed from the top of the fixed sleeve 6, and after the new filter element 13 enters the multi-way connecting pipe 1 4 and the multi-way connecting pipe 2 5, the old filter element 13 is pushed and replaced while the filtering position of the old filter element 13 is replaced, so that the new filter element 13 can filter the water entering the gas source heat pump body 1 from the multi-way connecting pipe 2 5 and the multi-way connecting pipe 1 4 while taking out the old filter element 13. This method of replacing the filter element 13 can replace the filter element 13 without affecting the gas source heat pump body 1. The air source heat pump body 1 enters the water body, so that the filter element 13 can be replaced without stopping the air source heat pump body 1, thereby achieving the replacement of the filter element 13 without affecting the water intake work of the air source heat pump body 1, and when the dust removal net plate 3 inside the blower 2 needs to be taken out, first pull the sealing cover 17 upwards, so that the sealing cover 17 drives the tightening spring piece 20 to move out from the inside of the clamping mouth 19, so that the fixed cover 18 is moved out from the top of the blower 2, and the dust removal net plate 3 can be pulled out from the inside of the blower 2 for cleaning, thereby achieving the effect of facilitating the removal of the dust removal net plate 3 for cleaning.
