[Industrial application field]

In this invention, a heater is installed in the main body of the cooking device, and the conductive heat from the heater is placed on top of the heater. An electric cooker equipped with a plate with good thermal conductivity that cooks food by heating. It is related to.

0002

[Conventional technology]

An example of a conventional electric cooker will be described with reference to figures. As shown in FIG. 5, the conventional electric cooker has a heater 22 at the bottom of the cooker main body 21. is arranged in the upper part of the cooking device main body 21 (above the heater 22). It is made of aluminum with good thermal conductivity and has a textured surface that cooks food using conductive heat. A plate 23 treated with fluorocarbon is placed, and is connected to the cooking device main body 21 and the heater. A heat shield plate 24 was disposed between the heat shield plate 22 and the heat shield plate 22 .

0003 A temperature adjustment knob 25 is provided on the upper side of one end of the cooking device main body 21, and A thermistor (not shown) is arranged below the rate 23, and the resistance of the thermistor is changed. A control unit (not shown) detects the temperature change and controls the energization of the heater 22 to adjust the temperature. The temperature of the plate 23 was adjusted to the temperature adjusted by the knot knob 25. Further, as shown in FIG. 6, the plate 23 and the heater 22 are integrally formed. Some did.

[Problem that the idea aims to solve]

If you have an electric cooker with the above configuration, the temperature will be adjusted using the temperature control knob. In order to control the temperature of the heater, the control section performs temperature control by intermittent power supply to the heater. However, when I put the food on the plate and started cooking, As a result, the temperature of the plate drops rapidly.

[0005] The control unit detects the resistance change of the thermistor at this time and adjusts the temperature of the plate. I tried to energize the heater to raise the temperature, but it was not adjusted again with the temperature control knob. Cooking takes a very long time to raise the temperature of the plate above to the desired temperature. There are problems with time delays and wasted power consumption.

[0006] The electric cooker of the present invention was created in view of the above problems, and takes advantage of the characteristics of oil. Improve the heat storage effect of the plate, shorten cooking time and save power consumption. This is the purpose.

[0007]

[Means to solve the problem]

In order to achieve the above objectives, the electric cooker of the present invention has the following features: A heater is installed in the cooker body, Thermal conductivity that allows food to be cooked by conductive heat from the heater on top of the heater. Place a good plate, forming a hollow part in the plate; Oil is sealed in the hollow part to form an oil layer.

[0008]

[Effect]

The electric cooker with the above configuration heats the plate by energizing the heater, and also heats the plate. The oil in the oil layer of the plate is heated, and when the plate reaches the cooking temperature, the food is heated. Place on a plate and cook. At this time, the heat from the plate is absorbed by the food, but due to heat accumulation in the oil in the oil layer. To cook food without rapidly lowering the temperature of the plate.

【Example】

An embodiment of the electric cooking device of the present invention will be described with reference to FIGS. 1 to 3. The electric cooker of the present invention includes a cooker body 1 and a cooker placed on the upper part of the cooker body 1. It is composed of a plate 2 and a lid 3 that covers the plate 2. The cooking device main body 1 has a heater 4 disposed in the lower part of the cooking device main body 1. (above the heater 4), the food is heated and cooked by conductive heat from the heater 4. The above plate is made of aluminum with good thermal conductivity and has a Teflon-treated surface. 2, and a heat shield plate 5 is arranged between the cooking device main body 1 and the heater 4. are doing.

0010 The plate 2 has a hollow center portion, and oil is sealed in the hollow portion to form an oil layer 6. is formed at the top corner of the plate 2 to hold excess when used when cooking food. An oil groove 7 for storing oil is formed.

[0011] Further, a plate detection switch for detecting the placement of the plate 2 on the cooking device main body 1 is also provided. A switch 8 is provided, and an operating portion 9 is provided at the upper end of one end of the cooking device main body 1. This operation unit 9 includes a temperature sensor 10 for detecting the temperature of the heater 4 and a temperature sensor 10 for temperature adjustment. and a knob 11, the temperature of which is adjusted by the temperature adjustment knob 11. Controls the temperature of port 2. The lid 3 is made of glass and has handles 12 on both sides. The lid 3 covers the plate 2 on top of the cooking device main body 1 when cooking food. This is to prevent oil etc. from scattering during cooking.

0012 The operation of the electric cooker having the above configuration will be explained. First, when the plate 2 is placed on the cooking device main body 1, the plate detection switch 8 is activated. When the placement of rate 2 is detected, it turns on and the temperature is set using the temperature adjustment knob 11 of the operation section 9. The heater 4 is energized by a control unit (not shown), and the plate 2 and the oil layer are heated. Heat the oil from Step 6.

[0013] At this time, the temperature of the heater 4 is detected by the temperature sensor 10, and the temperature of the heater 4 is detected by the temperature sensor 10. Based on the detection result, the control section controls the energization of the heater 4 to control the plate 2. Maintains temperature at set temperature.

[0014] When the temperature of the plate 2 reaches the set temperature, the cooked food is placed on the plate 2. Place the lid on, attach the lid 3, and start cooking. At this time, the heat of the plate 2 is taken away by the food and the oil layer 6 of the plate 2 is absorbed. Since the temperature of the oil is high, the temperature of the plate 2 increases due to the heat of the oil in the oil layer 6. This prevents the temperature from dropping suddenly like in conventional methods, allowing you to cook food in a short cooking time. It is possible to heat the food and save power consumption.

[0015] Furthermore, although the above-mentioned electric cooker has the plate 2 and the heater 4 separate, FIG. The plate 2 and the heater 4 may be integrally formed as shown in FIG.

[0016]

[Effect of the idea]

The electric cooker of this invention has a hollow plate and oil is filled in the hollow part. Since it forms an oil layer, when cooking the food, it is difficult to place the food on the plate. However, due to the heat of the oil in the oil layer that was heated by the heater, the The temperature of the plate does not drop suddenly like in the past, and the temperature of the plate can be raised again. It does not require a long time to heat up the temperature and can shorten the cooking time of food. It is possible to reduce power consumption.
