Abstract

PURPOSE:To surely control an electric current applied to a heating unit and to prevent a mistake in the time of throwing in cooking materials by detecting an infrared ray radiated from a heating receptacle having a heating unit by a sensor to control an electric current applied to the heating unit. CONSTITUTION:A heating unit 1 is disposed in the peripheral portion of the bottom of a heating receptacle 2, a thin wall portion 11 is formed in the substantially central portion of the heating receptacle 2, and an infrared ray temperature sensor 10 is fitted to the bottom of a body to receive an infrared ray R therefrom. Carrying handles 5 are provided on the body 7, and further legs 6 and a temperature display portion g are provided thereon. Though the temperature of oil 8 suddenly drops from a preset temperature T2 when materials are put in the receptacle (A point), the temperature of the thin wall portion 3 follows to drop, so that an electric current is applied to the heating unit 1 by onoperation of the infrared ray temperature sensor 10. When the oil temperature suddenly rises from T1 and returns to a preset temperature T2 (E point), the temperature of the thin wall portion 3 is detected by an infrared ray temperature sensor 11 and an electric current applied to the heating unit 1 is cut off to keep the preset temperature T2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric frying device for cooking tempura and the like.

2. Description of the Related Art A conventional electric frying device has a structure as shown in FIG. 3, for example. That is, a heat receiving section 103 is installed in a heating container 102 equipped with one heating element 101, and this heat receiving section 10
3 was equipped with a thermostat 7 104, and the heating container 102 was supported by a body 107 having a handle 106 and legs 106.

Problems to be Solved by the Invention In such a conventional configuration, the thermostat 104 that detects the temperature of the oil 8 in the heating container 102 and controls the energization to the heating element 101 is connected to the heat receiving part 103 located near the heating element.
Since the thermostat 104 receives heat transfer from both the oil 108 and the heating element 101, especially when the material is put into the oil 10B as shown in FIG.
(point), the oil temperature drops by T, 4C from the set temperature T2, and the thermostat 104 turns on, energizing the heating element 101, but due to the influence of heat transfer from the heating element 101, the oil temperature drops to T2. Before reaching this point, the temperature of the thermostat 104 rises and turns off (point B in Figure 4). Thereafter, while repeating this ON/OFF operation during the frying period (1), the oil temperature setting value reaches 2 (Fig. 4 G, D).
As shown in point E), if the oil temperature is below the set temperature from the time the ingredients are added until the frying process is complete, and the time to fry the food is long, do not cook tempura, etc. Not only was there a problem with not being able to deep-fry, but there was also the inconvenience of having to judge when to add ingredients because there was no oil temperature display.

The present invention solves these problems by quickly recovering the oil temperature to the set temperature even if the oil temperature drops due to material input, and displaying the oil temperature on the display to avoid mistakes in the timing of material input. The purpose is to provide an electric frying cooker.

Means for Solving the Problems In order to solve the above problems, the present invention detects infrared rays emitted from a heating container equipped with a heating element with an infrared temperature sensor to control the energization of the heating element, and This electric frying cooker is configured to display the temperature detected by the infrared temperature sensor on the display section.

Function: In the electric frying device having the above configuration, the temperature detected by the infrared temperature sensor has very little heat transfer from the single heating element, and faithfully follows the change in oil temperature, so the energization to the heating element can be controlled reliably. . Moreover, since the accurate oil temperature is displayed, it is possible to avoid mistakes in the timing of adding materials.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, 2 is a heating container, and a heating element 1 is disposed around the bottom. A thin wall portion 111r is formed at the bottom center of the heating container 2, and an infrared temperature sensor 10 is attached to the bottom of the body 7 so as to receive infrared rays R from the thin wall portion 11. The body 7 is provided with a carrying handle 5, as well as legs 6 and a temperature display section 9.

In the above configuration, as shown in FIG. 2, when the material is introduced (point M), the temperature of the oil 8 suddenly drops from the set temperature T2, but the temperature of the thin walled part 3 also falls following this, so the infrared temperature When the sensor 10 is turned on, the heating element 1 is energized, and the oil temperature rises, then rapidly rises and recovers to the set oil temperature T2 (
At point E), the infrared temperature sensor 11 detects the temperature of the thin wall portion 3, and the heating element 1 is energized +1OFFl to maintain the set temperature T2. Furthermore, the oil temperature detected by the infrared temperature sensor is displayed on the display. Note that the thin wall portion 3 is less affected by the heat transfer of the heating element 1, and therefore emits infrared rays corresponding to the temperature of the oil.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
An infrared temperature sensor that detects infrared rays emitted from the heating container controls the supply of electricity to the heating element while detecting the temperature of the oil, so it is possible to accurately detect changes in oil temperature while controlling the supply of electricity to the heating element. Since the energization can be controlled, the conventional problem of energization to the heating element being turned off before the oil temperature has recovered is resolved, and tempura, etc. can be fried appropriately, and the temperature of the oil can be displayed on the display. This eliminates the disadvantage of adding ingredients at the wrong time, making it possible to provide an extremely useful electric frying device.
