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 inner tank is heated. A through hole is bored in the tank at a position corresponding to the heat sensitive section, and the temperature inside the roasting chamber is sensed through the through hole to control the temperature.

However, in this type of configuration in which heat is sensed through a through hole, since there is a gap between the inner tank and the outer tank, 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 made in view of these points, and one embodiment thereof will be described below with reference to the drawings. 1 is an oven main body, and an outer tank 3 is disposed inside 2 with a space therebetween,
A door body 4 is pivotally attached to the front opening so that it can be opened and closed. A control panel 5 is formed on one side of the front, on which knobs such as a time switch, temperature regulator, and power switch are mounted.

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. Roasting heaters 8, 8 are strung above and below inside the inner tank 6, and the terminal receivers 9 of the heaters are formed on the side wall surface 10 of the outer tank 3. the inner tank 6 at a position corresponding to
A heater connection port 11 is formed in the opening. Therefore, in the heaters 8, 8, after arranging the inner tank 6 in the outer tank 3, inserting the heater 8 into the heater connection port 9, and then inserting the terminal receiving part 9, which is provided in the outer tank 3, 9 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 body 13 is provided on the side wall 10 of the outer tank 3. It is attached to a mounting piece 14 connected to the heat-sensitive section 12 and can be adjusted by an adjustment knob 14 provided on the surface wall of the control panel 5.

Thus, the heat sensitive part 12 is attached to the side wall 1 of the outer tank 3.
The mounting piece 14 at one end is positioned on the outer surface side of the outer tank 3, and the temperature regulator main body 13 is attached to the mounting piece 14.
is attached in a heat conductive manner, and a heat sensing piece 15 at the other end is formed to extend toward the front opening side with a gap S provided between it and the side wall 10 of the outer tank 3.

On the other hand, the inner tank 6 is provided with a protrusion 17 that bulges outward at a proper position on the side wall 16 so that the heat-sensitive part 12 is located in the inner tank, and the heat-sensitive part 17 is formed on the rear wall of the protrusion. When the inner tank 6 having such a structure is housed in the outer tank 3, the heat sensitive part 12 is inserted into the slit 1.
8 and is located in the inner tank 6. Therefore, the heat sensing portion 12 can reliably sense the temperature inside the inner tank 6 without being affected by the convection heat generated in the gap 19 formed between the outer tank 3 and the inner tank 6.

In the present invention, a gap is formed between an outer tank having an open front surface, an inner tank inserted into and removed from the outer tank, and a side wall of the outer tank, and a gap is formed to extend toward the front opening side. a heat-sensitive part of a temperature regulator that controls the energization of the roasting heater; a protruding part that bulges outward to accommodate the heat-sensitive part in the side wall of the inner tank; The heat sensitive part is located within the protruding part and does not protrude into the inner tank even when it is stored in the inner tank and the outer tank. Therefore, even if objects to be roasted or shelves are stored in the inner tank, they will not hit the heat-sensitive part and cause damage, and the protruding part will also prevent the thermal influence of convective heat generated within the gap on the heat-sensitive part. It is something that can be prevented. Since the heat-sensitive portion is directly exposed to the inside of the inner tank, the temperature inside the inner tank can be accurately detected.
