Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is an electrical device that allows the set temperature of the appliance body to be obtained in two stages using one temperature controller with one point adjustment. Regarding cooking utensil sets.

(Prior Art) In a conventional electric cooker set, for example, the electrical connection to the heating element of the appliance body a of a hot plate as shown in FIG. 9 is made by a connector b with a thermostat mechanism shown in FIG. There is. Plug receiver d of connector b to terminal part c, c on device body a side,
d, and the heat-sensitive rod e on the connection part b side to the 11th
As shown in the figure, it was inserted into the heat sensitive part f on the side of the main body a of the instrument to sense the temperature of the plate surface and control the surface temperature. That is, the set temperature of the appliance body a of the electric cooker is regulated by the position of the heat-sensitive part f, and temperature control is performed by one-step adjustment.

(Problem to be solved by the invention) However, the desired cooking surface temperature may differ depending on the material to be cooked. For example, if the adjustment is in one stage and it is on the low temperature side, it becomes necessary to cook on the high temperature side. In this case, it becomes difficult to adjust the temperature.

Therefore, as seen in Japanese Utility Model Application Publication No. 50-137497, for example, a heat sensitive part is provided near the power supply terminal of an electric cooker and is connected to the main body of the cooker in a thermally conductive manner. includes a temperature sensing part thermally connected to the heat sensing part near the connector, a temperature controller that controls the power supply to the connector at one point in response to the temperature of this temperature sensing part, and a set temperature of this temperature controller. An electric cooker set is known which is provided with a dial for adjusting the temperature. This device controls the temperature of the main body of the device by appropriately adjusting a dial, but the configuration of the temperature controller and dial is complicated and expensive, and adjustment is also troublesome.

Furthermore, by using two temperature controllers with one-point adjustment, two
Stepwise control inevitably requires complicated and expensive equipment.

Therefore, the problem of the present invention is to provide an electric cooker set that can control the set temperature of the electric cooker in two stages using one connector having one temperature controller for one-point adjustment. be.

[Structure of the idea]

(Means for Solving the Problems) The electric cooker set of the present invention has a terminal portion on the outer surface of the electric cooker body, and first and second terminals connected to the appliance body with different degrees of heat conductivity. The heat-sensitive parts 2 are arranged symmetrically on both sides of the terminal part, and the connector is designed so that it can be connected to the terminal part even if the connector is turned upside down at will. can be connected to any heat-sensitive part.

(Function) Even if the temperature of the main body of the device is the same, a heat sensitive part with easy heat conductivity has good heat conduction, so the temperature becomes relatively high, and a heat sensitive part with poor heat conductivity has poor heat conduction, so it becomes relatively low temperature. Therefore, if both heat-sensitive parts are controlled to have the same temperature, the main body of the instrument will be relatively low temperature in the case of a heat-sensitive part with easy heat conductivity, and the main body of the instrument will be relatively high in the case of a heat-sensitive part with poor heat conductivity. become. Therefore, even if temperature controllers with the same control temperature are used, two temperature settings can be obtained for the appliance main body depending on which heat-sensitive part is made to be sensitive.

(Example) Hereinafter, the details of the present invention will be explained with reference to Examples of the present invention with reference to FIGS. 1 to 5. A is an electric cooker such as a hot plate, and 1 is this electric cooker A.
The appliance body has a cooking surface 2 on the top surface, a heating element 3 embedded in the bottom, and two terminals integrally branched from the appliance body 1 near the terminal part 4 led out from the heating element 3, as described later. Heat sensitive parts 5 and 6 are provided. Reference numeral B denotes a connector with a built-in temperature controller that is detachably attached to the main body 1 of the device. Inside the base 7, a temperature controller 8 for one-point temperature adjustment, such as a thermostat, is incorporated, and the temperature of this temperature controller 8 is incorporated. The sensing portion 9 is formed in the shape of a block, and is provided so as to protrude from the front surface of the base body 7 so as to be biased toward one side of the front and back directions of the base body 7 (vertical direction in the figure). Reference numerals 10 and 10 denote a pair of connectors electrically connected to the terminal portions 4 and 4 on the instrument main body 1 side. The temperature sensing section 9 is connected to this connector 1.
They are arranged in the front and back direction with a constant step difference α of 0 and 10.

Among the heat sensitive parts 5 and 6, the first heat sensitive part 5 protrudes downward near the side edge of the instrument main body 1, and the terminal part 4
The temperature sensing section 9 can be contacted well above the. Further, the second heat sensing portion 6 is integrally projected downward from the bottom surface near the side edge of the device main body 1 and is bent into an L shape, so that the temperature sensing portion 9 can make good contact below the terminal portion 4. It's becoming like that. The steps between both heat sensitive parts 5 and 6 and the terminal part 4 are all arranged symmetrically with respect to the terminal part 4 at α,
By inserting the connector B upside down with the connectors 10, 10 as the center, the temperature sensing portion 9 selectively contacts any one of the first heat sensing portion 5 and the second heat sensing portion 6 described above. I'm starting to be able to do it. However, as is clear from the figure, the length of the first heat-sensitive section 5 from the device body 1 is significantly shorter than that of the second heat-sensor section 6, so that heat is not well conducted from the device body 1. , so the temperature is high. In comparison, the second heat-sensitive section 6 has a longer length from the instrument main body 1, so heat conduction is poor and the temperature is relatively low.

Next, we will discuss the effect. First, as shown in the second diagram, the temperature sensing part 9 of the connector B is brought into contact with the first heat sensing part 5 which has relatively good heat conduction from the cooking surface 2, and the connectors 10, 10 When the cooking surface 2 is inserted and connected to the terminal portions 4, 4, the temperature of the cooking surface 2 can be controlled by the relatively low temperature _T1 of its temperature characteristics as shown in FIG. Also, the third
If the connector B is reversed and connected as shown in the figure, the temperature sensing part 9 will be connected to the second heat sensing part 6 which has relatively poor heat conduction.
Since the cooking surface 2 is in contact with the cooking surface ₂ , the temperature of the cooking surface 2 can be controlled by the temperature T2 having a relatively high temperature characteristic.

In this way, the temperature sensing part 9 of the one-point adjustment connector B
The first and second heat sensitive parts 5, 6 of electric cooker A
By bringing a desired one of them into contact, it becomes possible to adjust the set temperature in two stages, making it possible to cook at a set temperature that suits the cooking material.

6 to 8 show other embodiments of the present invention. In the embodiment described above, the temperature sensing portion 9 was formed in the shape of a block and was disposed so as to protrude from the base surface 7. The invention is not limited to this, but a rod-shaped temperature sensing portion 9a may be used as shown in FIG. 6, and both ends thereof may be supported inside the base body 7. In addition, corresponding to this, the heat sensitive part on the side of the device main body 1 is the seventh one.
As shown in FIG. 8, the temperature sensing portions 5a and 6a have approximately semicircular concave portions on their end faces, and the temperature sensing portion 9a is connected to the first heat sensing portion 5a or the first heat sensing portion 5a in a direction approximately perpendicular to the insertion direction. The second heat sensitive part 6a may be brought into contact with the second heat sensitive part 6a. This allows for smooth attachment and detachment of the device to the main body of the device, and since the temperature sensing portion is located inside, it is protected from drop shocks, etc., and the set temperature can be stabilized over a long period of time. Furthermore, since there is no protruding part in packaging etc., it can be easily carried out.
