Embodiment 1
[0049] Such as Figure 1 to Figure 13 As shown, the embodiment of the present invention provides a fresh air device, and the fresh air device includes: a casing and a heat exchange assembly.
[0050] Specifically, an air outlet 4 and an air suction port 2 are provided on one side of the housing, and this side is suitable for being installed indoors. The other side is provided with an air inlet 14 and an air outlet 12, and this side is suitable for being arranged outdoors. The heat exchange assembly is arranged in the casing. In the embodiment of the present invention, the heat exchange assembly includes a frame 22, a compression device and a total heat exchanger 17 arranged in the frame 22, and the total heat exchanger 17 is provided with a first heat exchange air channel 23 and a The second heat exchange air passage 37. Such as Figure 8 As shown, the air outlet 4, the first heat exchange air channel 23 and the air inlet 14 communicate to form an air inlet channel, and th...

In the working process of the fresh air equipment, under the action of external force, when a compression device compresses a total heat exchanger through a sealing part, the sealing part is unfolded along with compression of the total heat exchanger and folded along with springback of the total heat exchanger; the unfolded part of the closed part is suitable for preventing air flow of the compressed part of the total heat exchanger from passing through, and the uncompressed part of the total heat exchanger conducts gas heat and humidity exchange through the air inlet channel and the air exhaust channel. According to the embodiment, when the air volume is adjusted or the air flow direction is changed, the total heat exchanger is directly compressed through the closed part of the compression device, and the air heat and the moisture content can be adjusted through the uncompressed part in the total heat exchanger, so that an air adjusting valve does not need to be additionally arranged in the fresh air equipment; therefore, the internal wind resistance of the fresh air equipment can be reduced, and meanwhile, a gas flow field in the fresh air equipment is kept uniform.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a fresh air device. Background technique [0002] The fresh air system is based on sending fresh air into the room with special equipment on one side of the closed room, and then exhausting it from the other side to the outside by special equipment. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. It is connected to the indoor air distributor through pipes, and the outdoor fresh air is continuously sent into the room through pipes from one side to meet the fresh and high-quality air required by people's daily life. Then the other side uses a specially designed exhaust fan to discharge to the outside, forcing the formation of a fresh air flow field indoors. [0003] The fresh air system is usually equipped with a total heat exchanger. The working principle of the total heat exchanger is: when working, the indoor exhau...
