Abstract

PURPOSE:To operate a blower with the volume of its exhaust blast readily switched to an appropriate exhaust blast volume according to the volume of the consumed gas and improve the easiness of operation and safety by providing a control device which controls the blast volume of the blower by the signal sent from a sensor provided in a gas piping which is for detecting the flow rate of gas. CONSTITUTION:When a gas kitchen range 8 is operated, at first a sensor 7 detects the flow rate of the gas to send a signal to a control device 6, and then the most suitable exhaust blast volume is calculated by the control device 6, and an electric motor 2 is operated by an output corresponding to the most suitable exhaust blast volume, and the range hood is operated automatically in optimum operation. And, the state of use of the gas kitchen range is thereby found, and when the flow rate of the gas changes, the output of the motor 2 is accordingly automatically adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a range hood for exhausting oil smoke from a kitchen where gas cooking appliances are used.

Prior Art Conventionally, this type of range hood generally had a configuration as shown in FIG. That is, a blower 14 having a built-in electric motor 12 and blades 13 is provided in a box-shaped hood main body 11 with open front and bottom surfaces, and a front hood 16 is provided to cover the front surface of the hood main body 11. A switch 16 is provided on the front surface of the front hood 15, and the exhaust air volume is changed by operating the switch 16.

Problems to be Solved by the Invention In such a conventional configuration, the exhaust air volume must be changed each time the lower gas range 17 is used by operating the switch 16 on the front of the front hood 15. It is often very troublesome, and sometimes the switching operation is not performed or the operation is not appropriate, resulting in insufficient exhaust air volume compared to the amount of gas consumed, resulting in unsafe conditions. .

The present invention solves these problems, and provides a range hood that can easily switch to an appropriate exhaust air volume according to the amount of gas consumed and operate the blower, thereby improving operability and safety. The purpose is to

Means for Solving the Problem In order to solve this problem, the present invention provides a range equipped with a control device that controls the exhaust air volume of a blower based on a signal sent from a sensor that detects the flow rate of gas provided in a gas pipe. It consists of a hood.

Effect: With this configuration, the sensor sends a signal to the control device in accordance with the gas flow rate, and the control device uses this signal to control the blower to operate at an appropriate exhaust air volume.

Example Hereinafter, one embodiment of the present invention will be described based on FIG.

In the figure, reference numeral 1 denotes a hood body, which has a box-like shape with an open front and bottom surface, and is provided with a blower 4 having a built-in electric motor 2 and blades 3 inside. A front hood 5 is provided to cover the front surface of the hood body 1. A control device 6 is built inside the front hood 6, and is connected to a sensor provided in a gas pipe for detecting the flow rate of gas.

In the above configuration, when the gas stove 8 is operated, the sensor 7 first detects the gas flow rate and sends a signal to the control device 6. Next, the control device 6 calculates the optimal exhaust air volume and outputs the gas accordingly. The electric motor 2 is operated, and the range hood is automatically operated optimally. If the usage status of the gas stove changes and the gas flow rate changes, the output of the electric motor 2 is automatically adjusted accordingly.

Note that the output adjustment of the motor may be performed by well-known methods such as tap switching using a stator winding or adjustment by controlling an input power source, and the type thereof is not limited.

Effects of the Invention As described above, according to the present invention, by automatically changing the exhaust air volume of the blower according to the gas flow rate, an appropriate exhaust air volume can be obtained without any trouble. This solves the problem of insufficient exhaust air volume caused by mistakes, and significantly improves operability and safety.
