Abstract

PURPOSE:To simplify handling and further enhance safety by installing a temperature sensor in a recessed part of a heater unit so that it may stand and detecting a bottom temperature of a cooking pan by way of top glass. CONSTITUTION:A cooking utensil casing 21 having an opening in the upper part is provided with top glass 22 which covers the opening. Furthermore, a heater unit 26 is installed to the opening in a part of which is formed a recessed part 27. A temperature sensor 28 is installed to the recessed part 27 so that it may stand. A temperature detection section 29 installed to the tip is arranged to come to contact with the rear side of the top glass 22, which allows the temperature detection section 29 to detect the temperature of a cooling pan 31 by way of the top glass 22. At the same time, the top 16a of the heater unit 26 is brought into contact with the rear side of the top glass 22, which minimizes the heat leakage from the heater unit 26. Therefore, this construction protects the temperature detection section 29 so that it may not be subjected to the noise-related temperature effect.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention uses a halogen lamp as a heating source, and
The present invention relates to an electric heating cooker having a temperature control function.

BACKGROUND OF THE INVENTION Conventionally, this type of electric heating cooker is as shown in Fig. 2.
A top glass 2 is provided at the opening of the cooking device casing 1 having an open top, covering the opening, and a bottomed container-shaped heater case 3 having an oval planar shape is installed inside the opening of the cooking device casing 1.
A heater unit 6 is provided, which includes a heat insulating material 4 provided at a predetermined thickness on the inner bottom surface and inner peripheral surface of the heater case 3, and halogen lamps 5 mounted inside at regular intervals. Further, a socket 9 into which the jack 8 of the temperature probe 7 is inserted and connected is provided in one corner of the cooking device casing 1, and this socket 9 is connected to a control circuit 10 which controls the heater unit 6 based on the detection signal of the temperature probe 7.

Further, the sensor portion 11 of the temperature probe 7 can be detachably inserted into the cooking pot 12.

When cooking with the electric heating cooker configured as described above, place the cooking pot 12 on the top glass 2, insert the sensor part 11 of the temperature probe 7 into the cooking pot 12, and Connect the jack part 8 of 7 to the socket 9. The control circuit 10 detects the temperature of the food in the cooking pot and controls the power to the heater unit 6 to adjust the temperature.

Problems to be Solved by the Invention However, with the above configuration, in order to adjust the temperature, the jack part 8 of the temperature probe 7 must be connected to the socket 9, and the sensor part 11 must be inserted into the cooking pot 12. Therefore, there was a problem that the connection work was troublesome for the user.

Further, there was also a constraint that the cooking pot 12 had to be a special pot into which the temperature probe 7 could be inserted. Furthermore, since the temperature probe 7 is exposed above the top glass 2, it may become a nuisance for the user or may cause unforeseen situations such as accidentally dropping tempura ingredients into the oil if touched during cooking. This poses a problem that requires careful attention from a safety standpoint.

The present invention solves the above-mentioned problems, and eliminates the troublesome work of connecting a temperature probe and the constraints such as using a special pot.The present invention also eliminates the troublesome work of connecting a temperature probe and the use of a special pot. The purpose is to provide a heating cooker.

Means for Solving the Problems In order to solve the above problems, the present invention provides a cooking device casing with an open top, a top glass provided to cover the opening of the cooking device casing, and the above-mentioned 1! A heater that is disposed within the opening of the cooking device casing and whose upper surface is in contact with the back surface of the top glass, and whose planar shape is mostly circular and has a recessed part that is recessed inward. The heater unit includes a temperature sensor located in the recessed portion of the heater unit, and a temperature sensor having a temperature detecting portion in contact with the back surface of the top glass.

According to the above-described configuration, the present invention detects the temperature of the cooking pot through the top glass by a temperature sensor located in the recess of the heater unit installed inside the opening of the cooking device casing covered with the top glass, Since the control circuit controls the power of the heater unit to adjust the temperature, the temperature probe is not exposed on the top glass, and the troublesome work of connecting the temperature probe and the constraints of using a special pan can be eliminated. It is easy to handle and highly safe.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

In FIG. 1, 21 is a cooker casing with an opening at the top, 22 is a top glass provided to cover this opening, and 30
is a control circuit, and the configuration of these members is the same as in the conventional example. Reference numeral 26 denotes a heater unit disposed in the opening of the cooking device casing 21, and the heater case 23 is shaped like a bottomed container, which is mostly circular in plan view and has a recessed part 27 formed inwardly in a part thereof. and a heat insulating material 24 provided with a predetermined thickness on the inner bottom surface and inner peripheral surface of the heater case 23,
It is composed of halogen lamps 25 which are heat sources mounted inside at regular intervals, and the upper surface 26a thereof is in contact with the back surface of the top glass 22.

Reference numeral 28 denotes a temperature sensor, which is positioned upright in a recessed portion 27 formed in the heater unit 26, and a temperature detecting portion 29 disposed at its tip is in contact with the back surface of the top glass 2. This temperature sensor 28 is connected to a control circuit 30 that controls the power of the heater unit 26.

To explain the operation in the above configuration, the cooking pot 31 is placed on the heater unit 26 via the top glass 22, and the halogen lamp 25 is energized to start cooking. For example, if this cooking involves frying food, when the oil temperature reaches a temperature suitable for frying, the temperature detecting section 29 of the temperature sensor 28 detects the oil temperature via the top glass 22, and the temperature control circuit 30 operates to turn on the power of the halogen lamp 25. control.

Here, since the temperature sensor 28 is disposed in a recess 27 formed in the heater unit 26, the temperature detection part 29 of the temperature sensor 28 detects the temperature of the cooking pot 31 placed on the heater unit 26. It faces the bottom surface, and the temperature detection section 29 can detect the temperature of the cooking pot 31, that is, the oil temperature, through the top glass 22.

Furthermore, since the upper surface 26a of the heater unit 26 is in contact with the back surface of the top glass 22, less heat leaks out of the heater unit 26, and the influence of temperature noise on the temperature detection section 29 is also reduced.

As described above, according to the electric heating cooker of the embodiment of the present invention,
Since the temperature sensor 28 is disposed in the rich part 27 formed in the heater unit 26, the temperature detection part 29 of the temperature sensor 28 faces the bottom surface of the cooking pot 31 placed on the heater unit 26. The temperature of the cooking pot 31 can be detected through the top glass 22, and
Since the temperature sensor 28 is not exposed on the top glass 22, the electric cooking device is easy to handle and highly safe.

Effects of the Invention As is clear from the above-mentioned embodiments, according to the present invention, the temperature is increased in the rich portion of the heater unit whose planar shape is mostly circular and has a partially inward recessed portion. Since the sensor is positioned upright and configured to detect the temperature at the bottom of the cooking pot through the top glass, the temperature probe is not exposed on the top glass, and there is no need to worry about the troublesome work of connecting the temperature probe. It is possible to eliminate the constraint of using a pot, and provide an electric heating cooker that is easy to handle and highly safe.
