Problems solved by technology
[0016] Because of this structure, the switch and each electric motor are connected through a plurality of relays and relay contacts, so the wiring work for connecting the switch and the electric motor is troublesome.
[0017] In addition, it is costly due to the need for multiple relays and multiple relay contacts

Embodiment Construction
[0053] according to Figure 1 to Figure 7 The first embodiment will be described.
[0054] figure 1 It is a schematic front view of an intake / exhaust ventilation hood. On an upper surface 20a of a ventilation hood 20, a curtain 21, an exhaust blower 22, and an intake blower 23 are provided.
[0055] The suction side of the above-mentioned exhaust blower 22 opens in the ventilation hood, and the discharge side communicates with an unshown exhaust duct through an exhaust damper 24 .
[0056] The intake side of the intake air blower 23 communicates with an unillustrated intake duct through the intake damper 25 , and the discharge side communicates with the opening 21 a of the curtain 21 .
[0057] A switch device 30 is provided on the front surface 20b of the above-mentioned ventilation cover 20 .
[0058] This switch device 30 includes a weak wind switch 31 , a medium wind switch 32 , a strong wind switch 33 , a cutoff switch 34 , and a light bulb switch 35 .
[0059] If an...

The wiring operation connecting switch and electrical motor is simplified at the same time that two electrical motors and an electrical appliance can be operated at same time by operating a switch. Therefore, a first and a second contact points of strong wind switch connect to high-speed circuit of the two electrical motors, a first and a second contact points of middle wind switch connect to middle-speed circuit of the two electrical motors, one of the strong wind switch and the middle wind switch is held at ON position, meantime, which is cut off with switch to be OFF, and is linked with thestrong wind switch and the middle wind switch, an additional switch is set to operate ON, OFF, which is linked to the electrical motor (other electrical appliance), thus by operating any one of the strong wind switch, the middle wind switch and the cutting off switch, the two electrical motors and an electrical appliance can be controlled, the wiring operation is simple if connect the contact points of strong wind switch and middle wind switch to high-speed circuit and middle-speed circuit of the two electrical motors.
Description
technical field [0001] The present invention relates to an electric device control device and a switch device for controlling the operation of an electric device equipped with a plurality of electric motors, such as an intake and exhaust ventilator cover, through ON and OFF operations of a switch. Background technique [0002] In Japanese Unexamined Patent Publication No. 10-19331, an intake and exhaust ventilation hood is disclosed. [0003] This ventilation hood is provided with: the blower for exhaust that is driven by the electric motor for exhaust, the blower for intake that is driven by the electric motor for intake, and is opened by the electric motor that is arranged on the discharge side of the blower for exhaust. The closed exhaust damper and the intake damper opened and closed by the electric motor arranged on the suction side of the above-mentioned air intake blower. [0004] Moreover, by opening the intake damper and the exhaust damper, driving the exhaust blow...
