Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an opening/closing range hood in which a ventilation fan is turned on or off by opening and closing a door on the front of the hood body.

(Prior Art) Recently, kitchens are increasingly being constructed using system kitchens that can be freely laid out to suit the space and the lifestyle of the user.

This system kit is made by combining many different parts according to the user's preference, so the range hood is also an openable type with the front door of the hood body opening and closing, rather than the conventional boot type, in order to harmonize with other parts. A range hood is used.

In this opening/closing type range hood, the ventilation fan is turned on or off by opening and closing the door on the entire surface of the hood body.

However, this range hood had the inconvenience of having to close the door every time it was used because the ventilation fan would not stop operating unless the door was closed.

(Problems to be Solved by the Invention) The problem to be solved by the invention is that the ventilation fan always operates when the door is opened, and furthermore, the operation of the ventilation fan is stopped even when the door is open.

(Means for solving the problem) The technical means of the present invention to solve the above problem is that the hood body has a door switch that turns the ventilation fan ON or OFF depending on the opening and closing movement of the door, and The idea is to provide a tumbler switch that turns the ventilation fan on when the ventilation fan moves.

(Operation) According to the above means, as shown in Fig. 1, when the door is closed, the tumbler switch is ON, but since the door switch is OFF, the ventilation fan does not operate, and when the door is open, the door switch is ON. but
Since it is turned on and the tumbler switch is also turned on, the ventilation fan operates. If you manually turn off the tumbler switch while this door is open, you can stop the ventilation fan and restart it.
It can be activated by turning it ON.

When the door is closed, the tumbler switch is turned on, but since the door switch is turned off, the ventilation fan stops operating, and both switches that open the door are turned on again, and the ventilation fan is activated.

(Example) An embodiment of the present invention will be described based on the drawings.

In the figure, A is the hood body and B is the exhaust unit.

The hood main body A is a substantially rectangular box with the entire lower surface open, and the front plate is attached to the upper end of the box via a hinge etc. to form a door a, and the lower side of the door a can be pulled or returned. By doing so, it opens and closes centering on the upper end, and when the door a is pulled open, it forms almost the same shape as a boot, and when it is returned and closed, it forms a rectangular box.

An exhaust unit B is installed inside the hood main body A, a filter (not shown) is installed in front of the exhaust unit B, and a door switch 2 and a tumbler switch 3 are installed on the outside of the side surface b, respectively.

The exhaust unit B is composed of a casing 4, a ventilation fan 1 including a fan such as a turbo fan or a Sirotskov fan housed in the casing 4, and a motor 5 that drives and rotates the fan. At the same time, an exhaust duct 6 is connected to the upper surface.

The door switch 2 is a conventionally known device that is turned on and off by sliding a switch button 2a, and is electrically connected to the motor 5 in the exhaust unit B, and is mounted near the door a on the upper side b of the hood main body A.

The tumbler switch 3 is a conventionally well-known switch, and like the door switch 2, the tumbler switch 3 is connected to the exhaust unit B.
The motor 5 and the door switch 2 are electrically connected to each other in the electric circuit, and are provided near the door a at the bottom of the side b of the hood main body A.

When door a is closed, the switch button 2a is pressed on the back of door a and turned off, so the ventilation fan 1 is stopped. Conversely, when door a is opened, the switch button 2a protrudes. The operation of the ventilation fan 1 becomes ON.

On the other hand, the tumbler switch 3 is in the ON state due to the projection _a1 provided on the back side of the door, and this does not change even when the door a is opened.

Furthermore, tumbler switch 3 is turned on manually,
It is possible to turn off the fan, and when the switch 3 is turned on with the door a open, the ventilation fan 1 will operate.
When set to OFF, the operation will stop.

Then, when door a is closed, door switch 2 is
When the tumbler switch turns OFF, the tumbler switch 3
is always in the ON state.

(Effects of the invention) Since the invention has the above configuration, the ventilation fan always operates when the door of the retractable range hood is opened, and even if the door is open, the ventilation fan can be stopped or started by operating the tumbler switch. I can do it.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and FIG. 1 is a side view of the range hood with the door open, and FIG. 2 is an electric circuit diagram. In the figure, A... Hood body, B... Exhaust unit, 1... Ventilation fan, 2... Door switch, 3...
Tumbler switch.

Claims (1)

[Scope of utility model registration request] The hood body is equipped with an exhaust unit inside and has a front door that can be opened and closed, and is electrically connected to the exhaust unit, so that opening the door turns on the ventilation fan in the exhaust unit, and closing the door turns on the ventilation fan. A range hood that is provided with a door switch that turns off, and a tumbler switch that closes the circuit by closing the door between the circuit of the exhaust unit and the door switch.
