The present invention installs a control member for controlling the supply of energy and a control member for reducing the amount of energy in proportion to the temperature when the thermosensitive element of the energy supply path connected to the heat source detects a predetermined high temperature. In particular, the present invention relates to an operation control device of a frying cooker designed to maintain a proper temperature in frying cooking.

In a conventional gas cooker, a thermosensitive element is brought into contact with a bottom of a pan or other cooking utensil to sense the temperature of the bottom, and when the thermosensitive element detects a constant temperature of the cooker, the supply of energy to a heat source heating the cooking utensil is stopped. Formulas are generally known.

In this case, the thermosensitive element is formed at a position away from the heat source so as to reliably take only the temperature of the cooking utensil without directly receiving heat from the heat source. In the case of tempura cooking, especially temporo (food fried in oil with flour dough), for example, 230 ℃ is detected in the thermo sensor to cut off the heat source. The temperature in the vicinity of the cooking zone with which the thermosensitive element is in contact shows the temperature characteristics as indicated in A of FIG. 3A, but the temperature in the cooking zone that the flame directly touches when the gas burner is used as the heat source is the solid line of FIG. As indicated by the mark B, it may go up to 380 ℃, the ignition point of the frying oil, which leads to a fire report. This phenomenon is particularly likely to occur when the amount of oil is low.

In order to prevent this, it is also considered to lower the operating temperature of the thermosensitive element, but according to this, when the temperature of the cooking utensil reaches the set temperature during normal frying, the heat source is disconnected and the temperature of the oil rapidly decreases when the frying pan is put into the oil. It is difficult to lower down to 180 ° C, which is suitable for frying, and it is difficult to quickly raise it to a temperature of 180 ° C.

The present invention, in view of this phenomenon, by installing a control member for stopping the supply of energy and a control member for reducing the supply of energy in proportion to the temperature when the thermosensitive element of the energy supply path connected to the heat source detects a predetermined high temperature Its purpose is to obtain a device without any unreasonable points. A heat source 1 such as a gas burner is brought into contact with the bottom of a cooking appliance 2 such as a pot heated by the heat source 1 and according to the temperature of this bottom surface. In the case where the thermosensitive element 3 which operates correspondingly is provided, and the control member 5 which moves according to this thermosensitive element 3 is formed in the energy supply path 4 of the gas etc. which connected to the salt source 1, The thermosensitive element 3 is composed of a first thermosensitive element 3a and a second thermosensitive element 3b operating at a higher temperature than the first thermosensitive element 3a, and the control member 5 is subjected to the first thermostat. Temperature increases by moving in response to element 3a And a second control member 5b for controlling the supply of energy to be reduced, and a second control member 5b that moves in correspondence with the second temperature sensing element 3b and cuts off the supply of energy at a predetermined high temperature. do.

As shown, the valve is opened by the electromotive force of the thermocouple 6 which uses a gas burner as the heat source 1 and heats the flame of the burner 1 as the second control member 5b in the gas passage which is an energy supply path of the gas burner. Installed an electronic safety valve to keep it open.

In addition, the circuit 7 for inducing the electromotive force of the thermocouple 6 is such that the gas passage 4 is closed while the circuit 7 is opened by the operation of the bimetallic thermosensitive element 3b.

On the other hand, in the accompanying drawings, 8 denotes a switch provided side by side with the temperature sensing element 3 of the circuit 7 so that the circuit 7 is operated as necessary regardless of the operation of the temperature sensing element 3b.

In addition, a first control is provided in the gas passage 4 as the first control valve member, and the control member 5a is connected to the conduit 9 in the liquid container in the liquid-expandable first thermosensitive element 3a. The pressure actuating member, such as a diaphragm having a liquid chamber on the rear side, is operated to increase the pressure in the gas passage 4 when the pressure in the liquid chamber increases.

For example, when the first temperature sensing element 3a senses 200 ° C, the first control member 5a starts to reduce the amount of gas and the second temperature sensing element 3b senses 230 ° C. When the switch 8 is turned off when the second control member 5b is closed, the internal temperature of the cooking appliance 2, which is already heated by the ignition heat of the burner 1, is gradually increased. Will rise.

At this time, when the temperature near the first temperature sensing element 3a reaches 200 ° C., the first control member 5a starts to reduce the amount of gas, and the thermal power is weakened, so that the temperature rise of the oil becomes smooth as in the dotted line C of FIG.

In this state, since the temperature of the oil is very high, the temperature near the temperature-sensitive element of the cooking zone further increases to close the second control member 5b when the temperature reaches 230 ° C, the set temperature of the second temperature-sensitive element 3b. Shut off the supply completely.

As a result, the temperature of the oil can be pressed at about 360 ° C. which is equal to or lower than the flash point, and at the same time, the operation of the second temperature sensing element 3b is delayed, that is, the burner 1 is turned off. It is possible to prevent ignition by

Thus, this invention consists of the thermosensitive element 3 consisting of the 1st thermosensitive element 3a and the 2nd thermosensitive element 3b etc. which operate at the temperature higher than this 1st thermosensitive element 3a, and this control part 5 is comprised. The control unit 5 is moved in correspondence with the first thermosensitive element 3a, and the energy supply amount is increased when the temperature rises, which is composed of the first control member 5a, the second control member 5b, and the like. The first control member (5a) to control the side to reduce the temperature and the second control member (5b) for completely stopping the energy supply at a predetermined high temperature moving in accordance with the second temperature sensing element (3b) heat source ( 1) This operation not only stops at the predetermined temperature, but also controls its operation even at the intermediate temperature so that the temperature rise can be relatively slow, preventing only a part of the oil in the cooking zone from being heated excessively. Will be digested There is an effect that it can fry cooking.
