Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device in which, for example, a stove is provided in the center of a table, and the heating of a cooking plate above the stove can be automatically controlled.

Generally, in order to successfully perform baking without failure on a cooking plate, it is necessary to control the calorific value of the heat source during baking so that the cooking plate is always at a temperature suitable for the baked product.

When this control is done manually, it is not only troublesome, but also requires relying on intuition, which sometimes results in control errors and failures such as burning the baked product.

For this reason, we have been devising a means to detect the temperature of the cooking plate using a temperature sensor and automatically control heating.

The temperature detecting means for this cooking plate is a temperature detecting body that is brought into contact with the back surface of the cooking plate, but since the temperature detecting body is located on the side of the burner of the stove,
This corresponds to the position of the blade at the center of the back of the cooking plate, and in the case of a shoe king table, where a lid plate is fitted onto the top of the stove instead of the cooking plate, the blade is positioned downward by the thickness of the lid plate. I have to let it happen.

Therefore, the temperature sensing element is located at a position offset from the center of the back surface of the cooking plate and faces the cooking plate with a slight gap between them, so it is necessary to provide a protrusion on the cooking plate that contacts the temperature sensing element in order to measure heat conduction. be.

By the way, the cooking plate is removed from the top of the stove when cleaning or when the stove is not in use.When setting the stove to the lower side for cooking, if the direction is reversed, the protrusion of the cooking plate will not come into contact with the temperature sensor. This means that the desired heating control cannot be achieved.

. The main objective of the present invention is to provide a heating cooker that can perform baking without the above-mentioned troubles and failures.

According to the present invention, a cooking plate is removably provided above the heat source, and a temperature sensing body for detecting the temperature of the cooking blend is provided on the side of the heat source and below the cooking plate, and the temperature sensing body detects the temperature. The cooking plate is configured to control the amount of heating by the cooking plate, and on the back side of the cooking plate, each one of them projects at symmetrical positions with respect to one vertical plane and one of them
A plurality of protrusions are provided which always come into contact with the temperature sensing body.

In the heating cooker configured as described above, there are a plurality of protrusions at symmetrical positions on the back side of the cooking plate, and even if the cooking plate is set on the stove with its orientation changed, one protrusion always detects the temperature. The device is in contact with the body and performs the desired heating control, solving the conventional problems and making it possible to create a heating cooker that is easy to use.

Embodiments of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a table, and a heating cooker 3 is attached to an opening 2 in the center.

A heat source 9 is provided inside the heating cooker 3.

This heat source 9 employs a U-shaped gas burner.

A temperature sensor 16 is provided on the side of the heat source 9, and the temperature sensor 16 is connected to a flow rate control valve 18 provided on the gas path from the appliance plug 18 to the heat source 9.

The temperature sensor 16 is, for example, of a liquid expansion type, and operates the flow rate control valve 18 by expanding or contracting the liquid due to the detected temperature, thereby automatically controlling the increase or decrease of the calorific value of the heat source 9. It is.

A soup saucer 13 is provided on the upper surface of the cooking device 3, and a through hole 14 is provided in the soup saucer 13 to allow heat to be transmitted upward.

4 is a cooking plate detachably set on the heat source 9, the overall shape is almost symmetrical with respect to at least one vertical plane, and has legs 5 at the four corners, and is supported on the soup saucer 13 by the legs 5. At the same time, protrusions 10 and 11 that protrude downward are formed at symmetrical positions with respect to the vertical plane, and one of the protrusions 10 and 11 is connected to the temperature sensor 16.
It is designed to be in contact with

The temperature sensor 16 detects the temperature of the cooking plate 4 and automatically controls the amount of heat generated by the heat source 9.

Preferably, the cooking plate 4 is made of a material with excellent heat conductivity, such as aluminum, which has advantages such as uniform heat distribution and faster response to the temperature sensor 16. There is.

6, 7.8 are reinforcing ribs and heat soaking ribs formed on the back surface of the cooking plate 4.

With the configuration of the embodiment described above, the cooking plate 4 is placed on the heat source 9.
At the time of setting, the temperature sensing body 16 comes into contact with the protrusion 10 or the protrusion 11 to detect the temperature of the cooking plate 4, and automatically controls the calorific value of the heat source 9 via the flow rate control valve 17.

As a result, the cooking plate 4 is maintained at a temperature that allows the baked product to be finished well.

The protrusions 10 and 11 are formed at symmetrical positions with respect to one vertical plane of the cooking plate 4, so that misalignment between the temperature sensor 16 and the protrusions 10 and 11 due to missetting of the cooking plate 4 on the heat source 9 can be avoided. prevent contact.

That is, the temperature sensor 16 is set to the side of the heat source 9, that is, at a position offset from the center 15 of the cooking device 3, so as to receive as little heat from the heat source 9 as possible, and the protrusions 10 and 11 Since it is located on the back side of the plate 4 and is not visible during setting, for example, if only one protrusion 10 is formed, the cooking plate must be placed so that the protrusion 10 faces the temperature sensor 16. 4 is not necessarily set on the heat source 9, and it is conceivable that the cooking plate 4 may be mistakenly set on the heat source 9 with the protrusion 10 located on the opposite side that does not face the sensing body 16. In this state, the temperature sensing body 16 does not come into contact with the protrusion 10, so the heat source 9 is not controlled.

However, since the protrusions 10 and 11 are formed at symmetrical positions with respect to one vertical plane on the back surface of the cooking plate 4, no matter which direction the cooking plate 4 is set, the temperature sensor 16
Since it always comes into contact with either one of the protrusions 10 and 11,
The above-mentioned inconvenience does not occur.

The present invention has great practical value in a heating cooker in which the calorific value of the heat source is automatically controlled by a temperature sensor, since loss of control does not occur due to missetting of the cooking plate. .
