Abstract
The utility model discloses a local and remote control's exhaust fan, the characteristic is that local switch connects first control line one end, first control line other end connection director, and the one end of remote switch contact and connection second control line is equipped with to the controller bottom surface, and the exhaust fan wiring board is connected to the second control line other end, and the terminal surface before the exhaust fan casing is installed to the exhaust fan wiring board, is equipped with the fan of airing exhaust in the exhaust fan casing. The first control line is connected to the local switch 1. The exhaust fan is an exhaust fan with more than one speed level. The local switch is also connected to an external power source. The remote switch contact is conducted with the first control line, and the remote switch contact is conducted with the air exhaust fan. Bathroom and bathroom exhaust fans have 2 functions, one is the whole-room ventilation requirement; one is to rapidly remove the odor. The former can be remotely controlled by an intelligent system, and the speed is low or stopped; the latter is high speed operation. After the exhaust fan is controlled according to the mode, the high-speed operation time is reduced, and the effects of saving energy and ensuring the indoor environment are achieved.
Description
Technical Field
The utility model belongs to heating and ventilating air conditioner field, especially a local and remote control's exhaust fan.
Background
In the prior art, exhaust fans of bathrooms and toilets are arranged on ceilings, and can be manually selected to run at a low speed and a high speed according to the use condition so as to achieve the purpose of use control. However, the exhaust air quantity can affect the use effect of the dehumidification system, so that the high speed can be selected when people use the dehumidification system, and the low speed or the shutdown can be selected by the remote system under the automatic control when no people use the dehumidification system.
Disclosure of Invention
The utility model aims at improving the exhaust volume of bathroom and bathroom exhaust fan when the people use, and when not using, the humidity control effect in the whole building is guaranteed to the low-speed that becomes. The local and remote control exhaust fans are divided into 3 parts, and one part is a double-speed exhaust fan; one part is a control box; and a part is a key switch. The control box is connected with a power supply, a fan, a remote control signal and a local switch. When the local switch is on, the high-speed running is realized. When the local switch is off, the operation is controlled remotely and is low-speed or stopped.
The technical solution of the utility model is that, a local and remote control's exhaust fan, including local switch, first control line, the remote switch contact, a controller, the second control line, the exhaust fan wiring board, exhaust fan casing and the fan of airing exhaust, 2 one ends of its characterized in that local switch 1 connection first control line, 2 other end connection director 4 of first control line, the one end of remote switch contact 3 and connection second control line 5 are equipped with to 4 bottom surfaces of controller, 5 other end connection exhaust fan wiring boards 6 of second control line, exhaust fan wiring board 6 installs the terminal surface before exhaust fan casing 7, the fan 8 of airing exhaust is equipped with in the exhaust fan casing 7.
The first control line 2 is connected to the local switch 1.
The exhaust fan 8 is an exhaust fan of one or more speed stages.
The local switch 1 is also connected to an external power supply.
The remote switch contact 3 is in conductive communication with the first control line 2.
The remote switch contact 3 is conducted with the exhaust fan 8.
Compared with the prior art, the utility model has the advantages of as follows:
1. bathroom and bathroom exhaust fans have 2 functions, one is the whole-room ventilation requirement; one is to rapidly remove the odor. The former can be remotely controlled by an intelligent system, and the speed is low or stopped; the latter is high speed operation.
2. After the exhaust fan is controlled according to the mode, the high-speed operation time can be reduced, and the effects of saving energy and better ensuring the indoor environment are achieved.
Drawings
Fig. 1 is a schematic view of the assembly front view of the present invention.
Reference numerals: the remote switch comprises a local switch 1, a first control line 2, a remote switch contact 3, a controller 4, a second control line 5, an exhaust fan wiring board 6, an exhaust fan shell 7 and an exhaust fan 8.
Detailed Description
The invention will be further described with reference to the accompanying drawings
In the embodiment 1, under the normal working condition, the exhaust fan 8 is connected to the controller 4, the local switch 1 is turned on, and the exhaust fan 8 runs at a high speed; and (3) closing the local switch 1, operating the exhaust fan 8 according to a remote switch signal, and turning off the exhaust fan 8 when the local switch is turned on and turning off the exhaust fan 8 when the local switch is turned off.
The above embodiments are provided for illustrative purposes only, and are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the appended claims.
