Fresh air blower

Abstract

The invention relates to the technical field of air purification, in particular to a fresh air blower for heating fresh air. The fresh air blower comprises a shell, a main machine and a controller, wherein an outdoor air inlet and a fresh air outlet are formed in the shell; the main machine is located in the shell and comprises an induced draft fan and a heating device, and the heating device is close to the fresh air outlet; and the controller is electrically connected with the induced draft fan and the heating device. According to the fresh air blower, the main machine comprises the heatingdevice, and the heating device can be used for heating outdoor air entering a room, so that the problem that when the fresh air blower is used in winter, the indoor temperature is reduced is solved; and meanwhile, the heating device can also play a role in raising the indoor temperature to the temperature required by a user according to the needs of the user, and the experience of the user is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a fresh fan. Background technique [0002] The fresh air fan has an independent exhaust and air supply system. The polluted air is exhausted to the outside through the exhaust outlet, exhaust duct and exhaust fan, and the outdoor fresh air is sent into the room through the induced fan, air inlet duct and air inlet. . Because it is different from the cooling function of the air conditioner, the comfortable and clean air is especially favored by users during the changing seasons and daily indoor air circulation. [0003] However, in winter in the north, especially in the Northeast, since the minimum outdoor temperature is between minus 30 and minus 40, although the fresh air fan can realize the circulation of indoor air and outdoor air and reduce the carbon dioxide content in the house, it will also cause the indoor temperature to fluctuate. The problem is reduced by the...

Problems solved by technology

[0003] However, in winter in the north, especially in the Northeast, since the minimum outdoor temperature is between minus 30 and minus 40, although the fresh air fan can realize the circulation of indoor air and outdoor air and reduce the carbon dioxide content in the house, it will also cause the indoor temperature to fluctuate. The problem of reducing the intake of outdoor air

[0004] Therefore, it is necessary to propose a fresh air blower, which can solve the difficult problem in the prior art that the temperature of the fresh air released in the fresh air blower is lower than the temperature of the indoor air.
