[0031] It should be noted that, during operation, when installing the filter 3, first place the filter 3 on the support unit 4, the support unit 4 can make a certain angle between the filter 3 and the air source heat pump body 1, then adjust the position of the fixing unit 5 to move it out of the air inlet 11, and then flip the filter 3 along the support unit 4, so that the filter 3 is placed inside the air inlet 11, and the side of the filter 3 is in contact with the inner wall of the air inlet 11, and then adjust the fixing unit 5 to move it to the outside of the air inlet 11, and then After that, the fixing unit 5 fixes the filter 3. When the filter 3 is disassembled, the fixing unit 5 is unscrewed and then moved out of the air inlet 11, and then the filter 3 is pulled outward, and then the filter 3 is removed from the supporting unit 4. By setting up this device, the disassembly and assembly of the filter 3 can be completed quickly, and the filter 3 can be fixed at the outside of the air inlet 11. When affected by external wind force, it is not easy to shake in the air inlet 11, thereby reducing the possibility of damage caused by collision and improving the service life of the entire device.

[0032] In one embodiment, a mounting frame 2 for mounting the support unit 4 is fixedly provided at the lower end of the air inlet 11;

[0033] The support unit 4 includes a fixed plate 41 fixed on the mounting frame 2, a support frame 42 fixed on the upper end of the fixed plate 41, a support rod 43 passing through the support frame 42, and a rotating plate 44 sleeved on the support rod 43. A slot 441 for placing the filter net 3 is provided on the side of the rotating plate 44 away from the support rod 43.

[0034] This design, see Figure 7A threaded groove is provided on one side of the support rod 43, and a nut is threadedly connected on the threaded groove, which can facilitate fixing the support rod 43 to the support frame 42, and the rotating plate 44 is transitionally matched with the support rod 43. When subjected to external force, the rotating plate 44 can rotate along the support rod 43, thereby changing the angle of the slot 441, and inserting the filter 3 into the slot 441. The filter 3 fits the inner wall of the slot 441 and can be tightly fixed to the rotating plate 44. After the filter 3 is installed, the filter 3 is rotated, the rotating plate 44 rotates along the support rod 43, and then installed in the air inlet 11.

[0035] In one embodiment, a baffle 45 for limiting the rotation angle of the filter 3 is provided on one side of the mounting frame 2 located inside the air source heat pump body 1 .

[0036] This design, see Figure 7 When the filter 3 moves into the air inlet 11 , it abuts against the baffle 45 . The baffle 45 can limit the position of the filter 3 and install the filter 3 to a specified stability, that is, vertically set inside the air inlet 11 .

[0037] In one embodiment, the fixing unit 5 includes a fixing ring 51 fixed to the air source heat pump body 1 , a screw 52 threadedly connected to the inside of the fixing ring 51 , and a limiting plate 54 arranged on the screw 52 for limiting the filter 3 .

[0038] This design, see Figure 6 The limiting plate 54 is fixed to the screw 52. The limiting plate 54 is rotated to move it out of the air inlet 11. After the filter 3 is installed inside the air inlet 11, the limiting plate 54 is rotated, the screw 52 is threadedly engaged with the fixing ring 51, and then the limiting plate 54 moves to the side close to the filter 3, and then the filter 3 is abutted and fixed to complete the fixing work of the filter 3.

[0039] In one embodiment, a rotating block 53 is fixedly provided on one side of the screw rod 52 located outside the air source heat pump body 1 , and a limiting plate 54 is movably sleeved on the screw rod 52 .

[0040] This design, see Figure 6 At this time, the limit plate 54 is movably sleeved on the screw rod 52, and the rotating block 53 is rotated. The rotating block 53 is threadedly connected with the fixing ring 51, and then the rotating block 53 drives the limit plate 54 to move toward the side close to the filter 3, so that the limit plate 54 is abutted and fixed with the filter 3. The inner side of the air inlet 11 is provided with a side edge for supporting the filter 3, which can work together with the limit plate 54 to squeeze and fix the filter 3 between the side edge and the limit plate 54, thereby improving the stability of the installation of the filter 3.

[0041] In one embodiment, a contact plate 55 for fixing the filter screen 3 is disposed on one side of the limiting plate 54 close to the filter screen 3 .

[0042] This design, see Figure 6 The abutment plate 55 can easily penetrate into the interior of the air inlet 11 to improve the stability of fixing the filter screen 3.

The condenser 16 is connected to the evaporator 14 through an expansion valve 17. An air outlet 12 is opened at the upper end of the outer shell, and a fan 13 is arranged inside the air outlet 12.

[0044] This design, see Figure 5 When the air source heat pump body 1 is running, the evaporator 14 absorbs heat energy from the environment, and the compressor 15 inhales low-temperature and low-pressure medium gas, which is compressed by the compressor 15 into a high-temperature and high-pressure gas state and enters the condenser 16. The high-temperature medium releases heat to heat the hot water, and passes through the expansion valve 17 to become a low-temperature and low-pressure gas. It enters the evaporator 14 to absorb heat and then enters the compressor 15 again for high-temperature compression to start the next round of heat generation, and this cycle is repeated to achieve the purpose of continuous heating.
