Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature control device for an electric oven. Generally, the temperature control of electric ovens is
A heat sensitive part of a temperature controller provided on the inner wall of the roasting chamber senses the temperature of a heater installed in the roasting chamber, and controls the energization of the heater.

However, in recent years, the inner tank serving as the roasting chamber has been designed to be detachable from the outer tank, making it easier to remove the inner tank from the outer tank and clean it.
With this type of removable configuration, it is impossible to install a temperature controller in the inner tank, which is the roasting chamber.In general, the heat-sensitive part of the temperature controller is attached to the inner wall of the outer tank, and the temperature controller is attached to the inner wall of the outer tank. A through hole is bored at a position corresponding to the heat sensitive part,
The temperature is controlled by sensing the temperature inside the roasting chamber through the through hole.

However, in this type of configuration in which heat is sensed through a through hole, there is a gap between the inner tank and the outer tank, so convective heat is generated in the gap and convective heat is also added to the heat sensing part that senses heat through the through hole. Accurate temperature sensing was not possible.

The present invention has been developed in view of these points, and one embodiment of the invention will be described below with reference to the drawings. Reference numeral 1 denotes an oven body, an outer tank 3 is disposed within an outer box 2 with a gap, and the front opening of the oven body is shown. A door body 4 is pivotally attached to the door so that it can be opened and closed. A control panel 5 is formed on one side of the front surface, and a time switch, a temperature regulator, a power switch, etc. are mounted on the control panel 5.

Reference numeral 6 denotes an inner tank that is removably inserted into the outer tank 3, and the inner tank also forms the roasting chamber 7. Heaters 8, 8 for roasting are suspended in the inner tank 6, and the butterfly receiving portion 9 of the heater is formed on the inner wall surface 10 of the outer tank 3, and the terminal receiving portion 9 is formed on the inner wall surface 10 of the outer tank 3. A heater connection port 11 is formed in the inner tank 6 at a corresponding position. Therefore, the heaters 8, 8 are arranged in the inner tank 6 within the outer tank 3.
After arranging the heater 8, the heater 8 is inserted into the heater connection port 9, and then inserted into the terminal receiving portions 9 provided in the outer tank 3 to complete the installation.

Reference numeral 12 denotes a heat-sensitive part of a temperature regulator that controls the energization of the heaters 8, 8 suspended in the roasting chamber 7. The temperature regulator main body 13 is provided on the inner wall surface 10 of the outer tank 3. control panel 5
Adjustment knob 1 attached to the inner wall of the
4 allows adjustment.

Since the heat sensitive part 12 is for sensing the temperature inside the inner tank 6, a through hole 15 is provided in the inner tank 6 at a position corresponding to the heat sensitive part 12.
A cylindrical wall 16 facing the outer tank 3 is formed at the periphery of the through hole. Therefore, outer tank 3
The structure is such that the heat sensitive section 12 faces within the frame of the cylindrical wall 16 with the inner tank 6 disposed therein.

A rising wall 17 is also formed at the peripheral edge of the heat-sensitive section 12 provided in the outer tank 3, and the rising wall 17 has an opening 18 at its front position, that is, on the side where the door body 4 is located. The cylindrical wall 16 formed in the inner tank 6 is fitted into the raised wall 17. That is, by inserting the inner tank 6 into the outer tank 3 from the opening side, the cylindrical part 16 formed in the inner tank 6 is slid and inserted through the opening 18 of the rising wall 17, and the fitted state shown in FIG. 3 is achieved. This is the result. However, the gap 19 formed between the outer tank 3 and the inner tank 6
The convection heat generated in the cylindrical wall 16 and the rising wall 17
As a result, the heat sensing portion 12 senses the hot air inside the roasting chamber 7.

As described above, the present invention comprises an outer tank whose front opening is opened and closed by a door body, an inner tank which is equipped with a heater to form a roasting chamber and which is inserted and removed from the front opening, and an inner side of the outer tank. a heat sensitive part of a temperature regulator that is provided on a wall surface and controls electricity supply to the heater; and a rising wall that is formed on an inner wall surface of the outer tank so as to surround the heat sensitive part and that is open on the front opening side. and a through hole bored in the side wall surface of the inner tank at a position corresponding to the heat sensitive part, and a through hole inserted through the opening part and into the rising wall so as to cover the heat sensitive part at the periphery of the through hole. When inserting the inner tank into the outer tank, the cylindrical wall slides to guide the inside of the rising wall, making insertion easy and transparent. The hole can be reliably opposed to the heat-sensitive part, and the effect of heat convecting in the gap between the inner tank and the outer tank on the heat-sensing part is completely suppressed by the double walls of the upright wall and the cylindrical wall. It is something that can be prevented.
