Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a deep fryer used for frying tempura.

[Summary of the invention]

The present invention allows a cook to know the temperature state and overheating state of tempura during frying without taking up much space by incorporating a tempura oil temperature reporting device into the handle of a tempura frying pan.

[Conventional technology]

Conventionally, devices have been known to control the temperature of food cooked on gas stoves, etc., but all of these devices are built into gas appliances and measure the temperature of food indirectly; for example, they use infrared rays. Methods such as detecting radiant temperature using sensors are used.

[Problem that the invention seeks to solve]

When frying tempura, the temperature of the oil has an important relationship with the quality of the tempura, and it is also known that if the temperature of the tempura oil gets too high, there is a risk of it catching fire. However, when measuring the temperature of tempura oil using a conventional indirect method such as measuring radiant temperature, in addition to the temperature of tempura oil, the radiant temperature of the part of the pan that does not contain oil (the amount of oil and (It varies depending on the size of the pot.) Errors occur due to the influence of the temperature of the gas flame, etc. Therefore, at present, a tempura oil temperature detection device has not yet been put into practical use.

The present invention aims to provide a deep fryer equipped with a frying oil temperature reporting device for accurately measuring the temperature of the cooking oil and informing a cook of the temperature state of the cooking oil.

[Means for solving problems]

The present invention is a tempura oil temperature reporting device that measures the oil temperature by directly inserting a temperature sensor (temperature sensing element) such as a thermistor, thermocouple, or resistance thermometer into the tempura oil, and reports the temperature status of the tempura oil. It was designed to be incorporated into the handle of a tempura pot.

[Effect]

Since the temperature of the tempura oil is directly monitored, there is no error, and a tempura frying pan equipped with a reliable tempura oil temperature reporting device that does not require any particular space can be obtained.

In this embodiment, a device housing section is further added to the end of the original handle (3) of the pot. In the examples shown in FIGS. 1 and 2, the position of the sensor is fixed, but in the example shown in FIG. 3, the position of the sensor can be articulated in the vertical direction. FIG. 4 is a partial sectional view showing an example of the adjusting means. In the same figure, (34) is a projection provided on the handle (3) and having a hole through which the sensor tube (4) passes, and is threaded on the outer periphery.

It has a hole through it. To adjust the sensor position, carefully tighten the gasket fastener (15) and tighten the sensor tube (4).
) and hold it in an appropriate position, then tighten the gasket tightener (15
), the sensor tube (4) will be fixed in that position.

Next, we will discuss the temperature detection/sound generation circuit mounted on the printed circuit board. When using a thermistor as a temperature sensor, the resistance value of the sensor changes depending on the temperature value, so this can be used to design a temperature detection/sound generation circuit. FIG. 5 shows the principle of an example of a basic temperature detection/sound generation circuit. In the figure, E is a battery, SW is a switch,

For example, the temperature of tempura oil is 170°C, just before the appropriate temperature of 180°C.
To detect this, by adjusting and setting the values of resistors R1, R2, and R3, the output of COM can be set to a high level when the temperature reaches 170°C, which turns on transistor TR and turns on buzzer BZ. can ring. Furthermore, in order to detect a temperature that is more generous than the dangerous temperature of 370° C. for tempura oil, for example, 240° C., a comparison circuit 21 having a similar configuration is used.

〔Effect of the invention〕

As explained above, the present invention has the following remarkable practical effects.

(b) A tempura oil temperature reporting device that detects the temperature by dipping the temperature sensor directly into the tempura oil is built into the tempura pot, so when using the tempura pot, the cook can check the exact temperature of the tempura oil. By knowing this, you can use your time effectively and with peace of mind.

(b) Since the tempura oil temperature reporting device is built into the handle of the pot, it does not take up space and is easy to handle and use.
