[0002] Existing fresh air air purifiers are used to chemically decompose various air pollution particles to improve air cleanliness and achieve purification functions. Air pollution particles include PM2.5, dust, pollen, odor, formaldehyde, etc. At the same time, since traditional air purifiers can only perform internal circulation indoors and cannot discharge indoor polluted air outdoors, fresh air air purifiers achieve the fresh air function by inputting fresh air from outdoors into the room. However, in winter or summer, the temperature difference between indoor and outdoor is large, and heat recovery of the air is required. Existing fresh air air purifiers cannot solve the thermal efficiency problem and increase energy consumption. Similar technologies can refer to Chinese utility model patent CN207262695U.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of the present utility model is to provide a fresh air air purifier that can effectively solve the above technical problems. When the bypass mode is turned on, the cold and hot air do not exchange temperatures, while when the bypass mode is turned off, cold and hot air are exchanged, thereby reducing energy consumption.

[0026] Example: Figure 1-6 As shown, the utility model discloses a first embodiment of a fresh air air purifier, which includes: a purification body 100 that can be placed on a horizontal surface and has a return air port 122, an air supply port 142, a fresh air port 162, and an exhaust port 182; a return air cavity 120 located in the purification body 100 and connected to the return air port 122; an air supply cavity 140 located in the purification body 100 and connected to the air supply port 142; a fresh air purifier 162 located in the purification body 100 and connected to the fresh air purifier 16 ... A fresh air chamber 160 connected to the outlet 162, an exhaust chamber 180 located in the purification body 100 and connected to the exhaust outlet 182, a heat pump core 200 arranged in the purification body 100 and located between the air supply chamber 140 and the fresh air chamber 160, a bypass valve 460 arranged in the fresh air chamber 160 and connected to one side of the heat pump core 200, a fresh air fan 320 arranged in the return air chamber 120, and an exhaust fan 340 arranged in the exhaust chamber 180.

[0027] Purifier 100 also includes a partition 150 positioned between return air chamber 120 and fresh air fan 320, located on one side of heat pump core 200, and having a partition through-hole 152. Partition through-hole 152 is located at the top of partition 150 and is used to install rivets, rivet nuts, or coils. Fresh air inlet 162 is located above exhaust port 182, while air supply port 142 is located above return air inlet 122.

[0028] The heat pump core 200 is located between the return air chamber 120 and the exhaust air chamber 180. The heat pump core 200 extends perpendicular to the horizontal plane and has a hexagonal cross-sectional shape.

[0029] The fresh air fan 320 and the exhaust fan 340 are three-phase AC permanent magnet synchronous motors with outer rotors.

[0030] This embodiment also includes a return air filter 420 arranged adjacent to the air supply chamber 140 and located on one side of the heat pump core 200, a fresh air filter 440 arranged adjacent to the fresh air chamber 160 and located on one side of the heat pump core 200, a water receiving tray 500 located at the bottom of the heat pump core 200, a drain pipe 520 one end of which is connected to the water receiving tray 500 and the other end of which is located outside the purification body 100, and a main controller 600 located between the return air outlet 122 and the exhaust outlet 182.

[0031] The purifier body 100 further includes a front access panel 110 disposed at the bottom of the water receiving tray 500, a peripheral side panel 130 for shielding the purifier body 100, and a top panel located on top of the peripheral side panel 130. The front access panel 110 is used for maintenance of the wall-mounted device.

[0032] The main controller 600 has at least two operating modes: 1) The fresh air fan 320 starts operating, drawing outdoor air into the room through the supply vent 142. The exhaust fan 340 then starts operating, drawing indoor air out through the exhaust vent 182. Water generated by the heat pump core 200's heat exchange process enters the water tray 500 and is discharged through the drain pipe 520. 2) The fresh air fan 320 starts operating, drawing outdoor air into the room through the supply vent 142. This air then passes through the bypass valve. The exhaust fan 340 then starts operating, drawing indoor air directly out through the exhaust vent 182, bypassing the bypass valve. During this time, the heat pump core 200 is inoperative. For example, in winter, the cool outdoor air passes through the heat pump core 200, exchanging temperature with the warm indoor air. By the time it enters the room, it's already warmer, reducing air conditioning efficiency. In the bypass mode, outdoor air is drawn directly into the room, bypassing the heat pump core 200.

[0033] The utility model has the advantages that when the bypass mode is turned on, the temperature exchange between the cold and hot air does not occur, while when the bypass mode is turned off, the cold and hot air are exchanged, thereby reducing energy consumption.

[0034] The above are only preferred implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
