御幅がさらに大きくなるものであつた。 Conventionally, when adjusting the temperature of an electric pot, electric kettle, hot plate, etc., a plug-in thermostat has been used to turn the power on and off. FIG. 1 shows a plan view of an electric cooker, such as a conventional hot plate, showing that a heater 2, such as a sheathed heater, is cast or installed on the back side of a heat plate 1 made of aluminum or the like with good heat conduction. A hot plate 1 is formed. hot plate 1
A pair of leg handles 4 are attached to the ends of the heating plate 1 , and both ends of a heater 2 are provided on the other side of the heating plate 1 so as to converge from the back side of the heating plate 1 . FIG. 2 is a sectional view of the back surface of the hot plate 1 showing both ends of the heater 2;
FIG. 1 and FIG. 2 are shown together. The ends of the converged heaters 2 are parallel to each other, and the ends of the heaters 2 face one side of the hot plate and are directly connected to plug pins 11 in the case 5 that receives the plug-in thermostat 6. In the conventional example shown in FIG. 2, the terminal 14 of the heater 2 and the plug pin 11 are connected through the gaskets 13 at each end of the heater 2. Some are indirectly connected to the plug pin 11 of the case 5. The ends of the heaters 2 are parallel to each other, and on the back surface of the hot plate 1 between the ends of the heaters 2, there is a space between the ends of the heater 2 and parallel to both ends of the heater 2.
A cylindrical body 10 is provided into which a heat-sensitive rod 7 of a plug-in thermostat is inserted. In the conventional example shown in FIG.
5 is provided on the circumferential surface of the heater 2. and,
The plug-in thermostat 6 is provided with a temperature adjustment dial 8 on the top surface, a heat-sensitive rod 7 protrudes from the side surface, and holes are provided on both sides of the heat-sensitive rod 7 into which the plug pin 11 in the case 5 is inserted. When the plug pin 11 is inserted into this hole, power is supplied from the power cord 9 of the plug-in thermostat. The heat-sensitive rod 7 is the cylindrical body 1 of the heat plate 1
0, detects the temperature of the hot plate 1 heated by the heater 2, and converts the heat received by the heat-sensitive rod 7 in the plug-in thermostat 6 into mechanical operation,
The contacts of the plate-shaped thermostat are operated to control the power on and off in a slow or rapid manner. Conventionally, fast-acting plug-in thermostats 6 have a wide on/off range, with a temperature range of about 10
℃, and the temperature control range was too wide, which was inconvenient for temperature control in electric cookers.
Furthermore, if the control width, that is, the on/off width, is made small, problems such as chattering occur, which is unfavorable in terms of performance. That is, the temperature of the hot plate 1 is transmitted through the cylindrical body 10 and sensed by the heat-sensitive rod 7;
Since it is separated from both ends of the heater 2, the temperature of the hot plate 1 cannot be quickly sensed and transmitted to the heat-sensitive rod 7. With conventional slow-acting thermostats, the control range was small, so there was no need for prompt sensing, but with fast-acting thermostats, the thermostat itself has a large control range, so the temperature control range of the appliance is even wider. It was something like that.

りでなく、理想的な表面温度特性が得られる。 The present invention is an electric cooker devised to eliminate the above-mentioned drawbacks. Fig. 3 is a sectional view of the back side of the heating plate 1 of the electric cooker showing an embodiment of the present invention; Fig. 1;
The same members in FIG. 2 will be explained using the same reference numerals. Both ends of the heater 2 are provided converging on one side end of the back surface of the hot plate 1, and a plug-in thermostat 6 is installed on the back surface of the hot plate 1 between both ends of the heater 2. A cylindrical body 10 through which the heat-sensitive rod 7 is inserted is provided, and one heater 2 end is provided closer to the cylindrical body 10 than the other heater 2 end. In the embodiment shown in FIG. 3, the effective heat generating part of the end of the heater 2, that is, the part of the heat generating line 12, which is provided adjacent to the heater 2, is arranged to face the vicinity of the cylindrical body 10.
Furthermore, one end of this heater 2 is bent and placed closer to the other end. In addition, in FIG. 3 showing the embodiment, both ends of the heater 2, like a sheathed heater, connect the heating wire 12 and the terminal 14, and directly connect the terminal 14 and the plug pin 11, and connect the heater 2 end and the terminal 14. Although the terminal 14 is housed in the case 5 via the packing 13, an electric cooking device connected to the terminal 14 of the heater 2 and the plug pin 11 via a lead wire can also have the configuration of the present invention. moreover,
The hot plate 1, the cylindrical body 10, and the thick casting part 15 of the heater 2 may be formed integrally, or
A separate piece may be fixed to the hot plate 1 using means such as brazing or caulking. In the above electric cooker, when the cylindrical body 10 of the hot plate 1 is placed close to one end of the heater 2, from the time and temperature characteristic diagram in FIG. 4, A is the temperature characteristic of the plug-in thermostat,
B is the electric cooker temperature characteristics. a is the off point of the plug-in thermostat 6, and b is the on point. By placing one end of the heater 2 close to the cylinder 10, the temperature is earlier than that of the hot plate 1 other than both ends of the heater 2. The temperature is raised to 100%, and the 6 plug-in thermostat circuits are shut off. When the heater 2 is cold, the heat generated at both ends of the heater 2 does not rise as the other parts follow suit, so the heat quickly dissipates and the cooling speed increases, allowing the plug-in thermostat 6 to have a wide on/off range. was corrected, and there was a difference of about 10℃,
It can range from about 4°C to 5°C. Based on the above principle, the range of temperature rise and fall of the plug-in thermostat 6 becomes large, and the operating range can be corrected. Therefore, the temperature of the hot plate 1 exhibits characteristics out of phase with respect to the plug-in thermostat 6, and the control width becomes small. Then, the noise level generated between the contacts of the plate-shaped thermostat of the plug-in thermostat 6 is drastically reduced, and inconveniences such as radio wave interference are eliminated. Furthermore, it has the feature that the initial temperature overshoot, which was conventionally large, can be reduced, and not only can heat loss due to excessive heating be reduced, but also ideal surface temperature characteristics can be obtained.
