Description

[Detailed explanation of the idea] The present invention relates to a heat-extinguishing boiling device.

It is common knowledge that when heat-extinguishing boiling equipment has several recesses installed vertically in the oil tank, when heating from below, convection occurs in the oil only at the heating points due to the presence of the recesses, making it difficult to heat the entire oil evenly. there were.

Therefore, in the past, a method was used in which the entire oil tank was heated as shown in FIG.

However, when the oil tank is made of a metal container (one with good thermal conductivity) and the convection phenomenon of oil during heating is observed in detail, the convection of oil flows even along the circumferential surface of the recess, making the above common sense invalid. It turned out that.

From this point of view, the present invention provides a heat-extinguishing boiling device that can maintain the oil temperature at a constant temperature with an efficient amount of heat and perform proper cooking.

Next, one embodiment of the heat-dissipating boiling device according to the present invention will be described based on the drawings (FIGS. 2 and 3).

The drawing shows a removable closing lid 3 of a metal oil tank 2 containing non-flammable oil 1 with several cylindrical recesses 5 into which a boiling container 4 (e.g., vacuum container No. 650809) is fitted, In a heat-extinguishing boiling device that heats from below with a burner 6, there is a burner 6 that heats a part (area) of the back surface of the oil tank 2, and an oil temperature sensor connected to a thermostat 7 at a position in the oil tank 2 that is not above the burner 6. This figure shows a heat-extinguishing and boiling device in which the 8 is floatingly installed.

An inclined reflector plate 10 having exhaust holes 9 is provided at the back of the burner 6 to efficiently utilize heat.

Further, a bimetal thermometer 11 for oil temperature is installed in the oil tank 2 at a position far from the burner 6.

The burner 6 is set at a temperature (1
50°C).

When used, the automatic ignition dial 61 ignites the burner 6 and further ignites the pilot burner 60.

Eventually, when the oil temperature reaches the set temperature, the thermostat 7 is activated in response to an instruction from the sensor 8, and the set temperature is maintained by repeatedly extinguishing and igniting the oil.

Even if the burner 6 is reduced to heat a narrow portion of the oil tank 2, the temperature can be evenly transferred through heat conduction in the metal oil tank 2 and convection as shown by arrow A.

The above-mentioned partial area means that almost the entire back surface of the oil tank 2 is unnecessary, and in the embodiment apparatus, the entire temperature can be made uniform even with an area that is about one-eighth.

Although it depends on the number of recesses 5, approximately 1/4 to 1/8 is sufficient.

Incidentally, the burner 6 is preferably located at the rear of the apparatus for cooking purposes.

By reducing the area of the burner 6, the amount of wasted heat can be significantly reduced, making it extremely economical and reducing the product price.

Furthermore, since the number of burners 6 has been reduced, in order to ensure that the set temperature is evenly applied to a large number of recesses 5, an oil temperature sensor 8 is floated at a far position not above the burner 6 so as not to come into contact with the oil tank 2. The thermostat 7 is designed to function based on the temperature at a location that is not above the burner 6.

Furthermore, since the thermometer 11 that detects the oil temperature is also located away from the burner 6, it is convenient to be able to check the lowest oil temperature.

Since it is sufficient for a heat-extinguishing boiling device that the temperature of all the recesses is uniformly constant, the present invention, which adopts the minimum necessary configuration that meets this requirement, is extremely rational and economically practical. It has a certain value.
