Abstract

PURPOSE:To make a user's general needs satisfiable by providing a means in which a temperature of a cooking plane is detected to control a current for heating the cooking plane and next controlling the current so that a maximum cooking temperature is obtained at the beginning of turning on a start switch. CONSTITUTION:A temperature of a heater for a cooking purpose is detected by a temperature detection means 3. When a start switch 1 is turned on, an initial temperature setting means, in which a desired cooking temperature is set, is operated to give its output to a heater turning-on/off means 5 through a temperature setting means 2. On the other hand, a signal generated by turning on the switch 1 is inputted to the heater turning-on/off means 5, and a heater current is controlled to obtain a maximum cooking temperature for a prescribed period just after the switch is turned on. User's general needs that the maximum cooking temperature is wanted at the beginning of the cooking can be satisfied accordingly. Hence, the user can cook without correcting a scale of temperature used at the last time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric hot plate used in ordinary households.

(Prior Art) Conventional electric hot plates use a bimetallic thermostat temperature controller called a control master to adjust the temperature by adjusting a pointer to a desired scale using a rotary knob.

(Problems to be Solved by the Invention) With the configuration of the conventional electric hot plate described above, even when the user cooks fried noodles, etc. (using the highest temperature), the keep-warm temperature (lowest temperature) is used at the end of cooking. After use, I often simply pull out the power plug and leave the pointer scale at the last temperature used.

However, with electric hot plates, the temperature initially used is generally the highest temperature, so the next user must turn the temperature knob on the temperature controller again to set the temperature to the highest temperature when first using it. , which was time-consuming.

The present invention is a patent characterized in that it provides an electric hot plate in which the set temperature is initially automatically set to the highest temperature when the start switch is pressed.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a start switch that starts heating the cooking surface, a heater that heats the cooking surface, and a temperature of the cooking surface. temperature detection means for detecting; temperature setting means for setting the temperature of the cooking surface;
heater on/off means for turning on/off the heater to maintain the temperature of the cooking surface at the temperature set by the temperature setting means based on outputs from the temperature setting means and the temperature detection means; and when the start switch is pressed; and initial temperature setting means for initially setting the set temperature of the temperature setting means to a maximum temperature.

(Function) According to the above configuration, when the user presses the start switch, the set temperature is automatically set to the maximum temperature that is often used. There is no need to reset the temperature settings, and you can use it as is, so it is hassle-free and extremely easy to use.

(Example) An electric hot plate according to an example of the present invention will be explained with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing the configuration of an electric hot plate according to an embodiment of the present invention, and FIG. 2 is an operation flowchart of the electric hot plate according to the same embodiment. In FIG. 1, 1 is a start switch that starts heating the cooking surface, 2 is temperature setting means for setting the temperature of the cooking surface, 3 is temperature detection means for detecting the temperature of the cooking surface, 4 is initial temperature setting means, 5 is heater power supply/disconnection means, 6 is heater, T
is the cooking surface temperature, T8 is the set temperature, TL is the minimum temperature, TH
is the highest temperature.

When the start switch 1 is pressed, the initial temperature setting means 4 outputs an output to the temperature setting means 2 to set the set temperature to the maximum temperature. When the start switch 1 is pressed, the heater on/off means 5 uses the outputs from the temperature setting means 2 and the temperature detection means 3 as input, and turns on and off the heater 6 to set the temperature of the cooking surface to the temperature set by the temperature setting means 2. Adjust so that it stays the same.

With the above configuration, when the start switch 1 is pressed, the set temperature is first set to the maximum temperature.

Next, the operation will be explained.

When the start switch is pressed in step 11, the set temperature T8 is set to the maximum temperature T, l in step 12. If the set temperature T8 is not changed in step 13, step 14
In step 15, the heater 6 is energized until the cooking surface temperature T reaches the set temperature TS. If the set temperature TS is changed to a temperature between the minimum temperature TL and the maximum temperature Ta in step 16, the process returns to step 14, the heater 6 is energized, and the cooking surface temperature T reaches the set temperature 18 or higher in step 15. Then, the power supply to the heater 6 is stopped in step 17, and if the set temperature TS is not changed in step 18, step 19 is performed.
Wait until the cooking surface temperature T falls below the set temperature TS. If the set temperature T8 is changed in step 18, step 20
The set temperature TS is set to a new temperature, and the process returns to step 19. When the cooking surface temperature T becomes lower than the set temperature T8, the process returns to step 13, and steps 14 and 1
In step 5, the heater 6 is energized until the cooking surface temperature T reaches the set temperature T8.

The cooking surface temperature T is adjusted as described above, but the set temperature T
If T8 is not changed at all, the temperature will be automatically adjusted at the set temperature originally set by the initial temperature setting means 4, that is, the maximum temperature T8.

(Effects of the Invention) According to the present invention, when the start switch is pressed, the set temperature is initially set to the highest temperature that is most often used, so the user does not pay attention to temperature adjustment until almost the end of use. Since there is no need to distribute the information, it does not take much time and is extremely easy to use.
