Embodiment 1

[0055]

[0056] Such as figure 1 As shown, the present embodiment provides a fresh air conditioner. The fresh air conditioner includes an exhaust device 1. The exhaust device 1 includes an exhaust pipe 11 and an exhaust box 12. The exhaust pipe 11 and the exhaust box 12 are connected to form an exhaust channel. One end of the exhaust passage communicates with the room, and the other end communicates with the outside; a baffle 13 is provided at the junction of the exhaust pipe 11 and the exhaust box 12; the baffle 13 can be controlled to rotate to open and close the exhaust passage; when the baffle When the plate 13 opens the exhaust channel, the indoor air is discharged to the outside through the exhaust channel, and the rotation angle of the baffle plate 13 can be adjusted to maximize the flow cross-sectional area of ​​the exhaust channel to ensure the air volume; when the baffle plate 13 is closed, the exhaust air During passage, the outdoor air is prevented from pouring i...

Embodiment 2

[0093] The difference in Embodiment 1 is that by "controlling the fan 17 to operate at a fixed operating power, and controlling the baffle 13 to open at different rotation angles according to actual needs", the wind speed in the exhaust duct is adjusted; the baffle 13 has multiple rotation angles, Specifically, the included angle between the main body surface of the baffle plate 13 and the end surface of the first air inlet 1221 includes the first rotation angle a1, the second rotation angle a2 and the third rotation angle a3, and they increase sequentially, 0°≤ a1<35°, 35°≤a2<70°, 70°≤a3<100°.

[0094] The fresh air air conditioner also includes an angle sensor for detecting the rotation angle of the baffle 13; the turbidity sensor detects the indoor air turbidity H0 and transmits it to the controller; the controller rotates the baffle and operates the fan based on the indoor air turbidity H0;

[0095] When the indoor air turbidity H0 is less than the first preset turbidity H...

Abstract

The invention provides a fresh air conditioner and a control method. The fresh air conditioner comprises an air exhaust device; the air exhaust device comprises an air exhaust pipe and an air exhaust box which are sequentially connected and form an air exhaust channel; a baffle is arranged in the air exhaust channel; when air exhaust is not needed, the baffle closes the air exhaust channel under the action of a driving motor, so that outdoor air is prevented from entering a room through the exhaust channel; when air needs to be exhausted, the baffle opens the exhaust channel under the action of the driving motor, so that indoor air is exhausted to the outside through the exhaust channel under the action of a draught fan; when the turbidity degree of the indoor air is not serious, the draught fan operates at a first-stage operation power; and when the turbidity degree of the indoor air is serious, the draught fan operates at a second-stage operation power. According to the fresh air conditioner and the control method, the structure is simple, the automation degree is high, the operation power of the draught fan can be adjusted, the high air outlet amount is guaranteed, indoor turbid air is rapidly exhausted out of the room, and the indoor air quality is improved; and when the air is not exhausted, the baffle effectively seals the air exhaust channel, so that the outdoor air is prevented from flowing backwards into the room.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a fresh air conditioner and a control method. Background technique [0002] With the continuous development of the air-conditioning industry, an air conditioner with the function of exchanging and blowing fresh air has been introduced on the market; the fresh air device of the air conditioner can enter the fresh air from the outside into the room, and the exhaust device of the air conditioner can filter the dirty air in the room and discharge it. Put it outside, and complete the replacement of fresh air to blow fresh air; but when the air conditioner is not exhausted, the outdoor air will be poured into the room through the exhaust device. Some people propose to install a windshield in the exhaust channel. When the air conditioner is exhausting, under the action of the exhaust pressure of the fan, the windshield rotates along the wind direction and the exhaus...
