The rib 35 in contact with the heat-sensitive rod 33 is formed to have a length approximately equal to the protruding length of the heat-sensitive rod 33.

Problems to be Solved by the Invention In such a conventional electric cooker, when the shapes of the cooking plate 34 and the sheathed heater 32 are enlarged, heat is not transferred to the vicinity of the heat-sensitive rod 33 arranged at the end of the cooking plate 34. There was a problem in that the supply was reduced, the heat-sensitive rod 33 became difficult to sense heat, and the temperature regulator 31 could no longer adjust the temperature.

Therefore, the first object of the present invention is to provide an electric cooker that can improve the heat supply to the heat-sensitive rod even if it is large in size, and can easily adjust the temperature.

A second object is to provide an electric cooker that can efficiently transmit heat from a sheathed heater to increase the amount of heat supplied for temperature control.

A third object is to provide an electric cooker having a cooking plate that increases the temperature of the ribs in contact with the heat-sensitive rod in order to further increase the amount of heat supplied for temperature control.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a first means that includes a heating section main body having a reflecting plate therein, and a heater body disposed on the reflecting plate with both ends facing in one direction. a sheathed heater, a temperature regulator having a heat-sensitive rod protruding between both ends of the sheathed heater, and a cooking board that is removably placed on the sheathed heater; and the heat-sensitive rod are thermally conductively supported by a support member. The second means includes a sheathed heater having an inward protrusion that protrudes inward, and a bottom portion that is substantially parallel to the heat-sensitive bar, extending from both sides of the heat-sensitive bar to near the inward protrusion of the sheathed heater. It has ribs.

Effects of the present invention With the configuration of the first means described above, the heat at the end of the sheathed heater can be efficiently transmitted to the heat-sensitive rod via the support member, making it easier to control the temperature. Further, with the configuration of the second means, the heat from the inwardly protruding portion of the sheathed heater is transmitted to the heat-sensitive rod through the ribs, so that temperature control is further facilitated.

EXAMPLE Hereinafter, a first example of the present invention will be described with reference to FIG.

As shown in the figure, a reflecting plate 2 is provided inside the heating section main body 1, and the reflecting plate 2 has a shape similar to a wrench whose center part protrudes inward.
A sheathed heater 3 formed in a shape is fixed by a fixing member 4, and both ends are arranged in one direction, and the heating section main body 1 is provided with a temperature regulator 5, and the temperature regulator 5 is equipped with a sheathed heater 3. A heat-sensitive rod 6 protruding between the ends of the sheathed heater 3 is provided, and the ends of the heat-sensitive rod 6 and the sheathed heater 3 are thermally conductively supported by a support member 7 formed in a substantially U-shape that is in contact with both. There is.

To explain the operation in the above configuration, the sheathed heater 3
Since the heat at both ends of is transmitted to the support member 7, and from the support member 7 to the heat-sensitive rod 6, the heat-sensitive rod 6 can easily sense the heat of the sheathed heater 3, making temperature control easier. Therefore, even if the heating section main body 1 becomes large and the heat-sensitive rod 6 becomes difficult to receive the heat radiated from the sheathed heater 3, the heat of the sheathed heater 3 is transmitted to the heat-sensitive rod 6 via the support member 7, and the temperature is controlled by the temperature regulator 5. Adjustments can be made accurately.

Next, a second embodiment of the present invention will be described with reference to FIG. Note that the same parts as in the first embodiment are given the same numbers and detailed explanations will be omitted.

As shown in the figure, a contact portion 11 of a support member 10 that transmits heat from the sheathed heater 3 to the heat-sensitive rod 6 contacts the heat-sensitive rod 6.
is formed into a planar shape that matches the surface shape of the heat-sensitive rod 6.

With the above configuration, the surface of the contact portion 11 of the support member 10 comes into contact with the heat-sensitive rod 6, so that heat conduction from the sheathed heater 3 to the heat-sensitive rod 6 is good, and temperature control can be performed accurately.

Next, a third embodiment of the present invention will be described with reference to FIG. Note that the same parts as in the first embodiment are given the same numbers and detailed explanations will be omitted.

As shown in the figure, an inwardly protruding portion 3'' of the sheathed heater 3 is almost parallel to the heat-sensitive rod 6 at the bottom of the cooking board 20, which is removably placed on the sheathed heater 3, from both sides of the heat-sensitive rod 6.
A rib 22 extending to the vicinity is provided.

With the above configuration, the inward protrusion 3" of the sheathed heater 3
Since the heat from the heat sensor 116 is transmitted to the heat sensitive rod 6 through the ribs 22, the amount of heat transmitted to the heat sensitive rod 6 increases, making temperature control easier.

Effects of the Invention As is clear from the above description of the embodiments, the present invention has a support member that thermally and dynamically holds both ends of the sheathed heater and the heat-sensitive rod of the temperature regulator, so that the present invention can be enlarged and the sheathed heater can be Even if the amount of heat that reaches the heat-sensitive rod decreases, heat can be supplied to the heat-sensitive rod by transmitting the heat at both ends of the sheathed heater to the heat-sensitive rod, and the temperature can be controlled even if the main body is large.

Furthermore, the supporting member having a contact portion that makes planar contact with the heat-sensitive rod efficiently transfers heat from both ends of the sheathed heater to the heat-sensitive rod, increasing the amount of heat supplied and making temperature control easier.

Furthermore, since the rib shape of the cooking board extends to the inward protrusion of the sheathed heater, the temperature of the ribs increases, the amount of heat supplied to the heat-sensitive rod increases, and temperature control becomes easier.
