Abstract
The utility model relates to a bidirectional air exchange fan used for purifying indoor air. The structure of the utility model comprises an air blow wind shell and an air exhaust wind shell, wherein, barrel type vane wheels which are also named as through flow vane wheels are installed in the two wind shells, and a motor is installed on the right end of the air exhaust wind shell. The two wind shells are connected with a partition type air inlet and outlet passage, and the partition type air inlet and outlet passage is connected with a partition type air suction and exhaust hood through wall holes. The utility model adopts a design that the air blow wind shell and the air exhaust wind shell mutually rotate at an alternate angle to realize that one motor and one barrel type vane wheel can realize a bidirectional air exchange function; when the bidirectional air exchange fan exhausts indoor turbid gas, outdoor fresh air is led into a room, and one motor and one vane wheel realize effects of saving energy and lowering noise.
Description
The utility model is a kind of ventilation fan, particularly is used for the improvement of air purifier and ventilating fan.
In order to purify the air of a room, air purifier and ventilating fan kind are a lot of in the market.Because air purifier is indoor type, so peculiar smell and the floating dust of air purifier in can only the clean room, and can't reduce the carbon dioxide index.Outdoor carbon dioxide index is about 0.5%, and indoor as closing the doors and windows, the family of 3-5 mouth indoor carbon dioxide index in one night can surpass 3%.Ventilating fan can be discharged indoor gas, and improving room air, but the gas that replenishes during air draft all enters from door, window slit, thereby kicks up a large amount of dust.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned air purifier and ventilating fan, and what a kind of new construction was provided only finishes the dual direction ventilating fan that purifies the air of a room with two-way ventilation with cartridge type impeller of a motor.
The utility model is to realize like this.Dual direction ventilating fan, include the air-supply crust of weathering 1. with the air draft crust of weathering 2., the cartridge type impeller is installed 3. in the air-supply crust of weathering and the air draft crust of weathering, 4. air draft crust of weathering right-hand member installs motor, 6. the air-supply crust of weathering is connected with cellular-type turnover air channel with the air draft crust of weathering, and 7. cellular-type turnover air channel is connected with cellular-type suction fan housing again.
The utility model adopts cartridge type impeller of a driven by motor, to reach energy savings and to reduce noise result.The air-supply crust of weathering and the air draft crust of weathering, cellular-type turnover air channel and cellular-type suction fan housing with 90 ° of two mutual alternate angles are realized the fresh air in the suction chamber and discharge indoor muddy gas volume equating also two bursts of air-flow mutually noninterferes substantially.Cellular-type turnover air channel also makes easy for installation, cellular-type suction fan housing can guarantee to discharge gas can not be inhaled into indoor, again can be rainproof and worm, bird enter pipeline.
Description of drawings:
1. the blow crust of weathering, 2. the air draft crust of weathering, 3. cartridge type impeller, 4. motor, 5. shell, 6. cellular-type turnover air channel, 7. cellular-type suction fan housing.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is perspective view that the utility model removes shell.
Embodiment: dual direction ventilating fan, include the air-supply crust of weathering and 1. reach the negative shell of air draft 2., the cartridge type impeller is installed 3. in two crusts of weathering, 4. air draft crust of weathering right-hand member installs motor, 6. two crusts of weathering are connected with cellular-type turnover air channel, 7. cellular-type turnover air channel installing hole on by wall is connected with cellular-type suction fan housing, shell is installed at last 5..
Claims (2)
1. a dual direction ventilating fan includes the cartridge type impeller and 3. reaches motor 4., it is characterized in that the cartridge type impeller outer be equipped with the air intake crust of weathering 1. with the air draft crust of weathering 2.; The air intake crust of weathering and the air draft crust of weathering change an alternate angle mutually.
2. according to the described dual direction ventilating fan of claim 1, it is characterized in that 6. cellular-type turnover air channel has the separate gas stream dividing plate with cellular-type suction fan housing in 7..
