Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stovetop burner that is equipped with a temperature sensor that measures the temperature of the bottom of pots, kettles, etc. and can boil and cook tempura dishes at a fixed temperature.

[0002]

[Prior Art]

 A conventional example of this type of stove burner will be described with reference to FIG. The stove burner 10 has a slit-shaped main flame port 160 formed between the outer circumference of the main body 110 and the outer circumference of the burner head 120, and has a considerable gap with the sensor cover 130 in the central hole 18. The temperature sensor 2 accommodating the temperature sensitive element 21 is inserted through and installed so as to project on the cylindrical sensor cover 130, and the temperature sensitive element 21 is a main flame a formed in the main flame port 160. The influence of heat on the pan was very small, and the temperature sensor 2 was designed to accurately detect the bottom surface temperature of the pot, the pot 3, etc., that is, the cooking temperature. In the figure, reference numeral 150 is an air hole for the combustion air of the flame a.

[0003]

[Problems to be solved by the device]

 In most of the above-described conventional stove burners, most of the air rising in the center hole 18 easily passes between the temperature sensor 2 and the sensor cover 130. As a result, the combustion air flowing through the air holes 150 formed in the lower portion of the sensor cover 130 and flowing into the main flame a was extremely reduced.

[0004]

[Means for Solving the Problems]

 An embodiment of a stove burner according to the present invention will be described below with reference to FIGS. It is formed on the peripheral wall of a cylindrical sensor cover 13 formed at the center of the burner head 12 and formed at the upper side, and an air hole 15 is provided at the same position as the main flame port 16 or at a slightly upper position. A flange-shaped orifice 14 is formed and installed inside the cylindrical sensor cover 13 above the air hole 15, and the temperature sensor 2 in which the temperature sensitive element 21 is embedded in the tip of the narrow through hole 141 of the orifice 14. Is inserted through. Further, in FIGS. 3 and 4, since the central flame port 17 that is opened to the upper inside of the stove burner 2 is formed, in this case, the air hole 15 is directly in front of the central flame port 17 or slightly above it. It is formed.

[0005]

[Action]

 Since the air flow is suppressed by the flange-shaped orifice 14, most of the rising air from the central hole 18 is guided to the air hole 15 and sufficient combustion air is supplied to the flame a of the main flame port 16 so that combustion is performed. It will not be defective. Alternatively, in the case where the central flame port 17 is additionally provided, the rising air is similarly guided to the flame b of the central flame port 17 and is sufficient for the flame b and the flame a of the main flame port 16. Combustion air is supplied.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

A burner head 12 having a central hole 18 is fitted and attached to the burner body 11 of the stove burner 1, and a cylindrical sensor cover 13 extending integrally upward is formed to have substantially the same diameter as the body portion. Has been done. A state in which the temperature sensor 2 is supported by a support rod 22 so as to be vertically slidable on the axis of the sensor cover 13, the temperature measuring element 21 is embedded in the tip portion, and the pot 3 is placed on the tip portion. And is placed so as to closely contact the pot 3 with elasticity. Slit-shaped and radial main flame ports 16 are formed in the lower outer portion of the burner head 12 so as to communicate with the gas chamber 19. On the peripheral wall of the cylindrical sensor cover 13, there are three air holes 15 at equal intervals in the circumferential direction at the same position as the main flame port 16 or at the upper position of the main flame port 16 for combustion from the inside of the main flame port 16. It is used for ventilation holes. Further, a flange-shaped orifice 14 is formed in the upper part of the air hole 15, and the temperature sensor 2 penetratingly mounted in the central hole 18 of the orifice 14 is penetrated with a slight gap 141 and rises. The air flow is suppressed by the orifice 14. In FIG. 3, a central flame port 17 is formed on the inner upper surface of the burner head 12 so as to communicate with the gas chamber 19 and formed at three locations at equal intervals in the circumferential direction, three inside and one outside. In the cylindrical sensor cover 13, air holes 15 are formed at three positions at equal intervals in the circumferential direction at positions substantially facing the flame b formed in the central flame opening 17.

The pot 3 thus placed has a bottom of a flame a formed on the main flame mouth 16 provided on the outer periphery of the stove burner 1 or a flame formed on the central flame mouth 17 provided on the inside. Most of the combustion air heated by b and rising from the central hole 18 by the draft force is captured by the orifice 14 and bent, and is reliably guided to the flame a or flame b through the air hole 15. Therefore, sufficient combustion air can be obtained and combustion failure does not occur. Further, unlike the conventional case, the center of the bottom surface of the pan 3 is cooled by the ascending air, and the temperature is not lowered.

[0009]

[Effect of the device]

 In the stove burner according to the present invention, the main flame opening is formed on the outer peripheral portion of the burner head or the central flame opening is formed on the inner side of the burner head, so that heating is performed uniformly by the internal and external flames. An air hole is provided at a position corresponding to the main flame port provided on the outer peripheral portion or the central flame port provided on the inner side of the peripheral wall of the cylindrical sensor cover extending above the center of the stove burner, and Since an orifice is provided on the inner periphery of the cylindrical sensor cover at the top, almost all the air rising in the center hole is reliably guided to the air hole, and there is no shortage of combustion air, and the pot, pot It provides an effective stove burner with a temperature sensor that does not cool or cool the bottom of the stove.
