Referring to this, there is provided a temperature sensing apparatus for a gas stove, which comprises a sensor housing, a lid portion exposed above the sensor housing and abutting against the bottom surface of the cooking vessel, And a fixing bracket fixed to the outer circumferential surface of the pipe to fix the pipe to a predetermined position of the gas range. The fixing bracket has one end located in the sensor housing, And the other end exposed to the lower end of the pipe to transmit a temperature signal of the cooking vessel delivered through the lid unit.

When the cooking vessel is placed on the upper part of the gas range so that the bottom of the cooking vessel is seated on the lid unit after the fixing bracket is fixed at a predetermined position in the gas range, the sensor housing is guided to the pipe, .

Here, when the lid is pressed by the cooking vessel, the lid outputs the temperature of the cooking vessel through the lead wire, and the temperature signal output to the lead wire is transmitted to the control unit.

At this time, when the temperature of the cooking container is raised to a predetermined temperature or higher by sensing the temperature signal in the control unit, the supply of the gas supplied to the gas cooking stove is cut off and the flame is burned.

However, in the above-mentioned Patent Document 1, the lead wire exposed to the lower end of the pipe rises upward and downward and rubbes against the lower end of the pipe, and the continuous lead of the lead wire is peeled off and electric damage may occur. Particularly, The lead wire is fixed to the end of the pipe, and the lead wire is fixed to the end of the pipe, and when the sensor housing is moved by the fixing of the lead wire, tensile force is generated in the lead wire to break the lead wire, The bending portion of the lead wire is damaged or broken, so that it is troublesome to carry out the maintenance from time to time and the reliability of the product is deteriorated.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Referring to FIGS. 1 to 4, the sensing unit 100 is formed in a hollow shape with a bottom open and a thermally conductive plate 101 at an upper end thereof.

The sensing unit 100 senses the temperature of the cooking container and outputs a temperature signal through the lead 300.

The sensing unit 100 is guided by the shaft shaft 200 and is moved up and down.

The heat conduction plate 101 is brought into contact with the bottom surface of a cooking vessel (not shown) raised on a gas range (not shown) to receive the temperature of the cooking vessel.

The sensing unit 100 is formed at a lower end portion of the sensing unit 100 to block penetration of the soup falling downward on the outer circumferential surface of the sensing unit 100 into the sensing unit 100, (102).

The soup infiltration stopper (102) guides the soup flowing downward through the sensing unit to be radially spread and fall down to the bottom of the sensing unit (100).

The shaft shaft 200 is installed such that the upper end thereof is inserted into the sensing unit 100 and the other end thereof is exposed to the lower end of the sensing unit 100. The belt shaft 200 is formed with a strip- And a supporting protrusion 202 is formed along the inner circumferential surface corresponding to the groove 201.

The shaft shaft 200 guides the upward and downward movement of the sensing unit 100.

The extension grooves 201 prevent the broth from sticking to the lower end of the shaft shaft 200 by making the broth flowing downward on the shaft shaft 200 high.

The supporting protrusion 202 supports the outer circumferential surface of the lead wire 300 and blocks the sharp bending in a state of being in contact with the lower end of the shaft shaft 200.

The shaft shaft 200 extends downward from the support shaft 202 of the shaft shaft 200 at a lower end thereof and extends in a downwardly projecting light structure so that the outer circumferential surface of the lead shaft 300 extends downward from the lower end of the shaft shaft 200, And an expansion portion 203 is formed to prevent the contact portion from coming into contact.

The expansion portion 203 is formed to have a diameter that is relatively larger than the inner diameter of the shaft shaft 200 to prevent the outer surface of the bent lead 300 from contacting the lower end of the shaft shaft 200.

One end of the lead wire 300 is inserted into the shaft shaft 200 and the other end of the lead wire 300 is exposed to the lower portion of the shaft shaft 200. The outer circumferential surface of the lead wire 300 is connected to the support shaft portion 202 of the shaft shaft 200 And transmits the temperature signal measured by the sensing unit 100.

One end of the lead wire 300 is located inside the shaft axis 200 and receives a temperature signal transmitted to the heat conductive plate 101. The other end of the lead wire 300 is connected to a control unit (not shown) And transmits a signal to a control unit (not shown).

When the cooking vessel is placed on the sensing unit 100 exposed above the gas range, the bottom surface of the cooking vessel is brought into close contact with the heat conductive plate 101 of the sensing unit 100, And is moved downward with respect to the shaft axis 200 while being pushed downward by the load of the cooking vessel.

At this time, the lead wire 300 exposed to the lower end of the shaft shaft 200 moves downward in accordance with the upward / downward movement of the sensing unit 100, and is bent in a direction in which the control unit is installed.

That is, the lead wire 300 is pushed by the sensing unit 100 to be exposed at the lower end of the shaft shaft 200, and is bent to be curved in a direction in which the control unit is supported by the support protrusion 202.
