Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cooking device used in general households.

Conventional structure and problems thereof Conventionally, in this type of cooker, as shown in Figs. On the back side, a heating element 2 is arranged with the central part on the opposite side of the wiring part bent beyond the center line of the pot 1, and a wiring board 3 is provided to wire this heating element 2 to the power supply side. An automatic temperature regulator 4 which has a heat-sensitive rod 4a that energizes the heating element 2 via a wiring board 3 and senses its temperature, and controls the temperature of the pot 1, and a heat-sensitive device into which the heat-sensitive rod 4a is inserted. It was common to have a bar holder 5 on the back side of the pot 1. however,
In this configuration, when the heating element 2 is energized, wiring terminals are generally embedded in the vicinity 2a of the heat-sensitive rod receiver 5 of the heating element 2, so almost no heat is generated; Since the temperature of the receiver 5 is rising only due to the conduction heat _H1 from the other part 2b of the heating element 2, the temperature rise is delayed compared to the central part of the pot 1.
And an automatic temperature controller 4 inserted into the heat-sensitive rod holder 5
Since the heat is further delayed from being transferred to the heat-sensitive rod 4a, the temperature near the center of the pot 1 is extremely high when the automatic temperature regulator 4 is activated. As the temperature of the entire pot 1 becomes uniform due to conduction heat, the temperature of the pot 1 decreases and approaches the set temperature of the automatic temperature controller 4. By the way, if you measure the relationship between the temperature at the center of pot 1 and the energization time,
In the conventional configuration described above, in order to raise the temperature of the pot 1 more than necessary, the automatic temperature regulator 4 is activated first and it takes time for the temperature of the pot 1 to reach the appropriate temperature. Therefore, it is not easy to use and the electricity bill is high, making it extremely uneconomical. Furthermore, since the temperature of the pot 1 is extremely high, the surface treatment of the components and the pot also has poor durability, resulting in a problem that the product cannot withstand long-term use.

Purpose of the invention The purpose of the invention is to solve these conventional problems and provide a cooker that is easy to use, economical, and has excellent durability.

Structure of the invention In order to achieve the above object, the cooking device of the invention has the following features:
A metal pot, a heating element arranged on the back side of the pot and having the central part on the opposite side of the wiring section bent beyond the center line of the pot, and a wiring board for wiring the heating element to the power source side. , an automatic temperature regulator that controls the temperature of the pot, which has a heat-sensitive rod that energizes the heating element through the wiring board and senses its temperature; and an automatic temperature regulator that is provided on the back side of the pot. The heating element has a heat-sensitive rod holder into which a heat-sensitive rod is inserted, and the bent portion of the heating element and the heat-sensitive rod holder are connected. According to this configuration, heat from the high-temperature heating element is transferred to the heat-sensitive rod holder. Because the heat is transferred directly to the heat-sensitive rod, the temperature of the heat-sensitive rod holder rises quickly, and as a result, the heat conduction to the heat-sensitive rod of the automatic temperature controller also becomes faster, which means that there is a delay in the temperature adjustment mechanism working like in the past. Therefore, the temperature of the pot will not become abnormally high.

In addition, with the above configuration, the time required for the automatic temperature regulator to first operate and bring the temperature of the pot to the appropriate temperature is short, making it easy to use and reducing electricity costs, making it very economical. . Furthermore, the temperature of the pot does not become abnormally high, and the component parts and surface treatment of the pot do not deteriorate due to heat, resulting in excellent durability.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 3 and 4,
Reference numeral 11 is a metal pot whose surface is treated with fluorine resin (not shown), and 12 is a heating element arranged on the back side of the pot 11. It is bent beyond the center line of 11.
13 is a wiring board for wiring the heating element 12 to the power supply side;
Reference numeral 4 denotes an automatic temperature regulator that supplies electricity to the heating element 12 via the wiring board 13. The automatic temperature regulator 14 has a heat-sensitive rod 14a that senses temperature, and controls the temperature of the pot 11. Reference numeral 15 denotes a heat-sensitive rod holder provided on the back surface of the pot 11, into which the heat-sensitive rod 14a of the automatic temperature controller 14 is inserted. The bent portion 12a of the heating element 12 and the heat-sensitive rod holder 15 are connected to each other.

The operation in the above configuration will be explained. First, electricity is applied to the heating element 12 via the automatic temperature controller 14 and the wiring board 13 to raise the temperature of the pot 11. The heat H ₂ generated at the bent portion 12a of the heating element 12 is transmitted to the heat-sensitive rod 14a via the heat-sensitive rod holder 15, and when the temperature reaches the appropriate temperature, the automatic temperature regulator 14 operates to turn off the power. Then, when the temperature falls below a certain temperature, the automatic temperature regulator 14 works again and the power is turned on, and this operation is repeated thereafter. Therefore, heat is directly transmitted to the heat-sensitive rod holder 15 from the heating element bent portion 12a, which has a high temperature, so that the temperature of the heat-sensitive rod holder 15 increases quickly, and accordingly, the heat is transferred to the heat-sensitive rod 14a of the automatic temperature controller 14. Since heat conduction becomes faster, there is no delay in the operation of the temperature regulator 14, and the temperature of the pot 11 does not become abnormally high. By the way, if we measure the relationship between the temperature at the center of the pot 11 and the energization time, it will be as shown in FIG. Since the automatic temperature controller 14 works to bring the temperature of the pot 11 to the appropriate temperature in a short time, it is easy to use and the electricity bill is low, so it is very economical. Further, since the temperature of the pot 11 does not become abnormally high, the component parts and the surface treatment of the pot 11 are not deteriorated by heat, and therefore durability performance can be improved.

In the above embodiment, a porcelain-embedded heating element was used as the heating element, but as shown in FIGS. Alternatively, the heating element 12 may be cast integrally with the pot 11. Further, although the square pot 11 is used in the above embodiment, the same effect can be obtained by using a round or oval pot.

Effects of the Invention As is clear from the above embodiments, the cooking device of the present invention particularly connects the bent part of the heating element and the heat-sensitive rod holder, thereby improving the thermal responsiveness of the pot and the automatic temperature controller. As a result, it is easy to use because it takes a short time for the automatic regulator to start working and bring the temperature of the pot to the appropriate temperature, and it is very economical because the electricity bill is low. It is something. Furthermore, since the temperature of the pot does not become abnormally high, the component parts and the surface treatment of the pot will not deteriorate due to heat, and as a result, durability performance can be improved.
