Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance that is used in general households and whose cooking pot and heat source can be separated.

2. Description of the Related Art A conventional cooking device of this type has a structure as shown in FIG. In FIG. 3, reference numeral 1 denotes a cooking device main body on which a sheathed heater 2 is placed, and numeral 3 denotes a watt controller that controls the amount of power consumed by the sheathed heater 2.

Problems to be Solved by the Invention Generally, when cooking eggs using high-pressure cooking, where the temperature inside the pot is about 120°C, the temperature is too high and the cooking cannot be done properly, and when cooking white rice, the egg turns gray. There were problems such as storage. In addition, low-pressure cooking is required for dishes in which the temperature inside the pot is 5 to 10 degrees Celsius lower than the 100 degrees Celsius used in high-pressure cooking, for dishes where you want to reduce the amount of simmering or retain some of the texture. However, with such a conventional configuration, when a pressure cooker or the like is mounted for low-pressure cooking, the heat must be adjusted within a range where the weight does not operate, but the temperature inside the pot is Accurate low-pressure cooking is difficult because it is not known whether it is present or not. Also, even if you reduce the weight of the weight and lower the operating temperature, you still need to check that the weight has worked and manually adjust the firepower to reduce the amount of steam ejected, and therefore automatically There have been problems such as difficulty in performing accurate low-pressure cooking.

The present invention solves these problems, and aims to provide a cooker that can automatically detect the movement of the weight, control power consumption, and maintain an optimal low-pressure cooking temperature. That is.

Means for Solving the Problems In order to solve the above problems, the present invention provides a sensor section having a sensor that contacts the bottom surface of the pressure cooker in the center of the cooking hot plate, and the pressure caused by the operation of the weight. The temperature balance inside the pot is sensed using output fluctuations of the sensor, and the power consumption of the cooking hot plate is controlled so as to maintain a temperature 5 to 10 degrees Celsius lower than the equilibrium temperature. be.

Function: According to this configuration, it is sensed that the weight operates and the temperature inside the pressure cooker reaches an equilibrium state, and the temperature decreases by 50% from the equilibrium temperature.
Since the temperature is maintained at ~10°C lower, cooking can be automatically performed at the optimum low pressure cooking temperature.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2. In the figure, 1o is a heating plate 1 for cooking on the top.
1 is the cooking device body on which it is placed; 12 is the cooking hot plate 11;
It is a sensor part provided in the center of the sensor 13 inside.
is provided.

14 is a coil spring that urges the sensor 13 to the bottom of the pressure cooker 15; 16 is a steam outlet provided on the lid 1;
Reference numeral 18 denotes a weight, which has a conical portion 18a inside thereof, and forms a valve by bringing it into contact with the steam outlet 16. 19 uses the output fluctuation amount of the sensor 13 to sense the equilibrium of the internal temperature of the pressure cooker 16 due to the operation of the weight 18, and controls the cooking temperature to maintain the temperature 5 to 10 degrees Celsius lower than the equilibrium temperature. A control circuit 20 controls the power consumption of the hot plate 11, and 20 is a power switch.

The operation in the above configuration will be explained. power switch 20i
When turned ON, the cooking hot plate 11 becomes energized, and the temperature rises to heat the pressure cooker 15. pressure cooker 16
The temperature of the sensor 13 in contact with the bottom surface of the pressure cooker 15 increases in accordance with the temperature B inside the pressure cooker 15, as shown in FIG. 2A. When the temperature B inside the pressure cooker 16 reaches the temperature at which the weight 18 operates, steam is blown out from the steam outlet 16, so the pressure cooker 1
The rate of increase in the temperature B within 6 becomes smaller and eventually reaches an equilibrium state. Furthermore, the temperature A of the sensor 13 also increases at a slower rate. The temperature of A when the temperature rise value Δt for 6 seconds is 0.2℃ or less is defined as the equilibrium temperature T, and from this T 5 to 1
The control circuit 19 controls the power consumption of the cooking hot plate 11 so as to maintain the temperature T' which is 0° C. lower.

Effects of the Invention As described above, according to the present invention, the heating plate for cooking automatically senses the temperature equilibrium in the pressure cooker due to the operation of the weight, and maintains the temperature 5 to 10 degrees Celsius lower than the equilibrium temperature. Since the power consumption is controlled, low-pressure cooking can be performed automatically at the optimal temperature. In addition, even if the temperature sensed at the bottom of the pot changes due to changes in the steel used, the balance of temperature inside the pot is sensed and controlled, so there is no negative effect on optimal low-pressure cooking. can also be obtained.
