Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a gas stove mainly used for cooking food by heating.

(B) Conventional technology In recent years, a thermocouple has been used in a burner for a stove to detect misfire of the burner.
As shown in Japanese Patent Publication No. 1, the positioning is performed by the support portion integrally formed with the burner head, and the burner head has a complicated shape. Further, a combination of the burner for the stove and a temperature sensor for detecting the temperature of an object to be heated such as a cooking pot is disclosed in, for example, Japanese Utility Model Laid-Open No. 59-186628, in which case the supporting portion is simply constructed. However, the strength when a load is applied to the burner head is a problem.

(C) Problems to be solved by the present invention The present invention aims to fix a thermocouple for detecting misfire and abnormal combustion of a burner and a temperature sensor for detecting the temperature of an object to be heated easily and surely.

(D) Means for Solving the ProblemsThe present invention provides a downward projection on the bottom surface of the burner head of the burner for the stove, and inserts this projection into the engagement hole of the burner support plate to position the burner head. In this case, a supporting plate having an engaging hole which is opposed to the engaging hole and into which the protrusion is engaged is fixed to the upper surface of the burner supporting plate, and the burner for the stove is misfired at one end of the supporting plate. And a temperature sensor for detecting the temperature of the food to be cooked, which is located at the other end of the burner head and is located in the vent hole at substantially the center of the burner head.

(E) Action The engagement hole of the support plate is positioned opposite to the engagement hole of the burner support plate, the support plate is fixed to the upper surface of the burner support plate, and the thermocouple and the temperature sensor are fixed by the support plate, A projection provided with a burner for the stove on the bottom surface of the burner head is inserted into an insertion hole of the support plate and positioned to align the thermocouple and the temperature sensor with the burner head.

(F) Embodiment An embodiment of the present invention will be described first with reference to FIG.
Is a main body of a gas table stove with a grill, in which burners (2) and (3) for the stove are arranged on the left and right of the upper surface, and the inside of the burner and the grill (4) are formed. And the above body (1)
On the front surface of the stove are provided burners for stoves (2) and (3), cock knobs (5), (6) and (7) for blinking a grill burner (not shown), and a grill door (8).

Further, as shown in FIG. 2, the one stove burner (2) is provided with a vent hole (9) in the vertical direction at the substantially central portion of the burner head (2) ', as is well known. Burner head
A plurality of protrusions (10) and (11) having different heights are provided at the bottom end of (2) ′ so as to project downward, and the long protrusions (10) are included in the burner support plate.
Engage in the engaging hole (13) formed in (12).

As shown also in FIG. 3, (14) is screwed (15) (15) onto the portion of the burner support plate (12) including the engaging hole (13), and the engaging hole (13) is fixed. A support plate having an engaging hole (16) in which the protrusion (10) is opposed to each other, and a flame hole (2) ″ provided at the outer peripheral portion of the burner head (2) ′ at one end (14) ′. The mounting portion (18) for supporting the thermocouple (17) is bent so as to face the other end, and the other end (14) ″
An upper insertion hole (20) through which a cylindrical temperature sensor (19) accommodating a sensor such as a thermistor is placed at the upper end of the inside of the ventilation hole (9) at approximately the center of the ventilation hole (9), and the end is lowered. The end portion (21) is bent to form a lower insertion hole (22) through which the lower portion of the temperature sensor (19) is inserted.

On the other hand, the temperature sensor (19) is located below the upper insertion hole (20) and penetrates the spring pin (23), and a coil spring (21) is formed between the spring pin and the other end (21) of the support plate (14). twenty four)
Is attached to the support plate (14) and is always biased upward by the support plate (14), and is located inside the ventilation hole (9).
5) is stuck.

Reference numeral (26) is a hole cover integrally attached to the other end (14) ″ of the support plate (14) by spot welding or the like.
The cover (25) of (9) is connected to the cylindrical part (27) surrounding the upper insertion hole (20) from the lower end, and the upper end of the upper insertion hole (20) extends from the other end.
Support plate cover part (28) covering the support plate (14) over the (21)
Is formed.

Further, as shown in FIG. 4, the mounting portion (18) is formed by bending an engaging piece (30) which is engaged with the upper engaging groove (29) of the thermocouple (17) at the upper end, and A holding wall (31) is provided upright to surround the low temperature part (17) 'of the thermocouple (17) and guide the engaging piece (30) into the engaging groove (29). Bending piece (3) that prevents the thermocouple (17) from coming off from the storage groove (32) formed by the holding wall and the engaging piece (30) in place.
3) is formed, and this bent piece is a thermocouple in the storage groove (32).
Fold (17) after engaging.

Thus, the burner (2) for the stove has the protrusion (10) while inserting the temperature sensor (19) into the vent hole (9) of the burner head (2) '.
Is inserted into the engagement hole (16), the thermocouple (17) and the temperature sensor (19) are securely positioned and the burner support plate (12)
Placed on. In addition, the broth etc. that flowed through the pan (34) to the temperature sensor (19) traveled along the upper surface of the cover (25) and dropped from the lower end thereof, and then fell down along the outer peripheral surface of the hole cover (26),
The penetration into the insertion hole (23) and the attachment to the spring (24) are prevented.

(G) Effect of the Invention With the configuration of the present invention, the burner head of the burner for the stove can be reliably aligned with the thermocouple for detecting the misfire of the burner and the temperature sensor for detecting the temperature of the heated object. Prevent erroneous detection of thermocouple and temperature sensor.
