Abstract

PURPOSE:To enable to correctly sense the temperature on the bottom of a cooking pot always by a sensor, by providing a metal fitting to hold a sensor under a metal fitting to hold a heater, separated from the metal fitting to hold a heater. CONSTITUTION:A stove heater 11 is welded to projections 14 and 15 provided on a metal fitting 13 to hold a heater. Accordingly, the temperature in the metal fitting 13 rises extremely higher than that in metal fittings 16 and 17 to hold a heater which are separately provided. In this case, the other end of a metal fitting 24 to hold a sensor is hung on the metal fitting 13 in order to largely decrease conduction of heat from the stove heater 11. Therefore, only a small amount of conductive heat is transmitted to a sensor 20 from the metal fitting 13 through metal fittings 24 and 22 holding a sensor. Besides, a polygon part 23 in the center of a metal fitting 22 holding a sensor is molded in the shape so as to be linearly contacted to a sensor holding cylinder 18, so that heat is hardly conducted to the sensor holding cylinder 18 through the metal fitting 22 holding a sensor.

付勢されている。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. It is configured in an inverted triangular shape with a flat surface so as to make a lot of contact with the bottom of the pot 12,
A heater support fitting 13 extending toward the center is disposed on the lower surface thereof, and a protrusion 1 provided on the heater support fitting 13 is provided.
The stove heater 11 is supported by caulking at 4.16. 16,1a is the heater support fitting 1
These heater support metal fittings 16 and 17 are provided symmetrically with respect to the heater support metal fitting 13, so that the outer periphery of the stove heater 11 is approximately equally spaced. The other ends of these heater support fittings 16, 1 extend toward the outer periphery of the stove heater 11, and 018, which supports the lower surface of the stove heater 11, is connected to the stove heater 11. 11 is a sensor holding cylinder arranged in the center, 19 is a sensor holding cylinder 1
A sensor 20 made of a thermistor for detecting the temperature at the bottom of the cooking pot 12 is provided inside the sensor cover 19, and the sensor cover 19 is always kept upward by a spring 21, that is, It is urged in a direction away from the upper end of the sensor holding cylinder 18.

強固なものにしている。Reference numeral 22 denotes a sensor holding fitting having a polygonal part 23 in the center, which holds the sensor holding cylinder 18 by sandwiching it between the polygonal part 23, and both ends thereof are attached to the separate heater supporting fittings 16. .17, and is fixed to the heater support fittings 16 and 17. Reference numeral 24 denotes an FC sensor holding fitting having one end fixed near the tip of the polygonal portion 23 of the sensor holding fitting 22, and the other end of this sensor holding fitting 24 having a U-shaped hook portion 26 as shown in FIG. The hook portion 26 is hooked into the groove portion 26 provided below the heater support fitting 13 to firmly maintain the relative position of the sensor cover 19 with respect to the stove heater 11.

タ１１の熱による影響はきわめて少ないものである。In the above configuration, the stove heater 11 is caulked with the protrusion 14.15 provided on the heater support metal fitting 13, so the temperature of the heater support metal fitting 13 is much higher than the temperature of the separate heater support metal fitting 16.17. It is expensive,
Therefore, as described above, by hooking and locking the other end of the sensor holding fitting 24 to the heater supporting fitting 13, the heat of the stove heater 11 becomes conductive heat, and is transferred from the heater supporting fitting 13 to the sensor holding fitting 24. The polygonal part 23 in the center of the sensor holding fitting 22 is in line contact with the sensor holding cylinder 18, which can extremely reduce the possibility of the transmission of the signal to the sensor 20 via the sensor holding fitting 22. Therefore, this sensor holding metal fitting 22
□Also, since the separate heater support fittings 16 and 17 are simply mounting the stove heater 11, this heater The temperature of the support fittings 16 and 17 is low, so this heater support fitting 16.17
Even if the sensor holding fitting 22 is fixed to the sensor holding fitting 22, the influence of the heat from the stove heater 11 is extremely small.

易に行なえる。As shown in FIG. 4, the broken sensor holding fittings 22 and 24 are configured to have a substantially U-shape with the middle part between the polygonal part 23 in the center and the end part lowered downward, and A plurality of holes 27 are provided in each intermediate portion to reduce the heat conduction cross-sectional area and to increase the heat dissipation area by using the holes 27. The heat is transmitted from the heater support fittings 13, 16.17 to the sensor holding fittings 22.24, and as a result, the sensor 20 is affected by the heat of the stove heater 11, causing an arbitrary temperature rise. The sensor 2o is capable of accurately detecting the temperature at the bottom of the cooking pot 2. Also, the heater support fittings 13, 16, 17
On the other hand, since the sensor holding fittings 22 and 24 are also almost integrated, the position of the sensor cover 19 with respect to the stove heater 11 is precisely determined, and therefore it is possible to maintain high detection accuracy and to When the heater 11 is moved, the sensor cover 19 also moves together with the sensor cover 19, making it easy to clean the stove heater 11.
