Embodiment 1

[0017] Refer to attached figure 1 with 2 . The present invention comprises an exhaust cavity 1 and an air suction cavity 2. A volute 3, a centrifugal wind wheel 4 and a motor 5 are arranged in the exhaust cavity. The rotation path of the shell is provided with an exhaust port 7a leading to the outdoor and one or more exhaust ports leading to the room in cooperation with the volute exhaust port 6; The air suction port 8a leading to the outdoor and the air suction port leading to the room are paired with each other. The air suction chamber is provided with a damper 9 for switching the air suction port.

[0018] As an air duct, the volute can provide higher wind pressure, and the volute can also be replaced by other shaped casings, such as circular casings.

[0019] The present invention is provided with box body 11, and is divided into above-mentioned suction cavity and exhaust cavity by dividing plate 12, dividing plate is provided with air inlet 13, and volute air inlet 10 ...

Embodiment 2

[0026] Refer to attached image 3 , 4 . This embodiment is an outdoor installation type for two bedrooms, so the air-collecting pipe piece may not be connected to the air inlet leading to the outside and the exhaust port of the exhaust cavity.

[0027] Such as image 3 As shown, the rotatable damper is two circular arcs. In this way, when the damper is in the state that the air inlet leading to the outside is opened, the air inlet leading to the room is closed. By rotating the volute, the outlet is aligned with a certain air inlet. The exhaust port of the room can inhale fresh outdoor air for the room. When the state of the damper is that the suction port leading to the outside is closed, the damper opens the suction port of all rooms. By rotating the volute, it is aligned with the The outdoor exhaust port can discharge indoor dirty air to all rooms.

[0028] Others are the same as embodiment 1. The same parts in the two embodiments have the same reference numerals in the...

Abstract

The air exchanger includes air exhaust cavity, air sucking cavity and volute rotating driving mechanism. The air exhaust cavity is provided with volute, eccentric blower and motor, as well as exhaust port to outdoor and one or several exhaust ports to indoor. The air sucking cavity has air sucking port to the outdoor paired with the exhaust port to outdoor and air sucking ports to the indoor paired with the exhaust ports to indoor ,as well as air door for opening and closing the air sucking ports, and is communicated with the inlet port to the volute. The present invention can exhaust stagnant air from indoor and suck in fresh air from outdoor without altering the rotation direction of blower, has high wind pressure, great air exchange amount and high speed, and can realize the air exchange control to single or several rooms.

Description

technical field [0001] The invention belongs to an air exchanging device, in particular a ventilator designed to discharge indoor dirty air and inhale outdoor fresh air. Background technique [0002] Present ventilator can be divided into two classes, and a class is the ventilating fan that can only discharge indoor foul air outdoors, and another kind is the ventilator that both can discharge indoor dirty air and can inhale outdoor fresh air. For the latter type of ventilator, the current ventilation pressure is too small, and it can only achieve air exchange in a single room. For example, the blade type ventilator uses the positive and negative rotation of the blade to meet the requirements of air intake and exhaust. But therefore the exhaust efficiency of the fan blades is greatly reduced, and the wind pressure is too small to meet the requirements of a large amount of indoor and outdoor air and rapid exchange.
