Abstract

PURPOSE:To make a temperature of a cooking plane maximum at the beginning of using a hot plate by providing the following two means: a first means in which a heating temperature of the cooking plane is detected and it is controlled to be a prescribed one, and a second means in which application of power is detected and then a maximum temperature is set. CONSTITUTION:A temperature of a heater 7 functioning as a cooking plane is detected by a temperature detection means 4. This temperature detected by the means 4, a temperature set by a temperature setting means 3, and output information of power detection means 2 which detects whether power is applied or not, are outputted together to a heater turning-on/off means 6. A power application signal of the power detection means 2 is used to make an initial temperature setting means 5 generate an output signal which allows a temperature setting means 3 to set a maximum temperature. User's needs that a hot plate generally requires the maximum temperature upon the initial using of it can be satisfied, and there can be saved such a nuisance that a temperature knob of a temperature controller is turned again to adjust its scale to the maximum temperature at the beginning of using the hot plate.

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),
At the end of cooking, the keep-warm temperature (lowest temperature) is often used, and after use, the needle scale is often left at the last used keep-warm temperature simply by unplugging the power plug.

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.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electric hot plate in which the set temperature is initially automatically set to the maximum temperature when the power plug is inserted into an outlet.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a power supply detection means for detecting that a power supply is connected, a heater for heating a cooking surface, and a heater for heating a cooking surface. temperature detection means for detecting the temperature of the cooking surface; temperature setting means for setting the temperature of the cooking surface;
heater on/off means for turning the heater on or off so as 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; The apparatus further includes an initial temperature setting means for initially setting the set temperature of the temperature setting means to the maximum temperature when the connection is detected.

(Function) With the above configuration, when the user turns on the power, the present invention
Since the set temperature is automatically set to the highest temperature that is often used, in most cases there is no need to reset the temperature setting at the beginning, and you can use it as is, saving you time.
It is also very 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 both figures, 1 is a power supply, 2 is a power supply detection means for detecting that the power supply is connected, 3 is a temperature setting means for setting the temperature of the cooking surface, and 4 is a temperature detection means for detecting the temperature of the cooking surface. , 5 is initial temperature setting means, 6 is heater on/off means, 7 is heater, T is cooking surface temperature, Ts is set temperature, T
L is the lowest temperature, T and l are the highest temperature.

When the power supply detection means 2 detects the connection of the power supply 1, the initial temperature setting means 5 outputs an output to the temperature setting means 3 to set the set temperature to the highest temperature. When the power supply detection means 2 detects the connection of the power supply 1, the heater ON/OFF means 6 controls the temperature setting means 3.
With the output from the temperature detecting means 4 as input, the heater 7 is turned on and off to adjust the temperature of the cooking surface to be maintained at the temperature set by the temperature setting means 3. In this way, when the power source 1 is connected, the set temperature is first set to the maximum temperature.

Next, the operation will be explained.

When the power source 1 is connected in step 11, the set temperature T8 is set to the maximum temperature T in step 12. If there is no change in the set temperature T8 in step 13, the heater 6 is energized in steps 14 and 15 until the cooking surface temperature T reaches the set temperature Ts. If the set temperature T3 is changed to a temperature between the lowest temperature TL and the highest temperature T□ in step 16, the process returns to step 14, the heater 6 is energized, and the step 1
When the cooking surface temperature T becomes equal to or higher than the set temperature T8 in step 5, the power supply to the heater 6 is stopped in step 17, and if the set temperature T8 is not changed in step 18, the cooking surface temperature T becomes lower than the set temperature Ts in step 19. wait until Step 1
If the set temperature Ts is changed in step 8, the set temperature Ts is set to a new temperature in step 20, and the process returns to step 19. When the cooking surface temperature T becomes equal to or lower than the set temperature Ts, the process returns to step 13, and steps 14 and In step 15, the heater 6 is energized until the cooking surface temperature T reaches the set temperature TS.

The cooking surface temperature T is adjusted as described above, but the set temperature T
If s is not changed at all, the temperature will be automatically adjusted at the set temperature initially set by the initial temperature setting means 5, that is, the maximum temperature TM.

(Effects of the Invention) According to the present invention, when the power plug is inserted into an outlet, the set temperature is initially set to the highest temperature that is most often used. There is no need to pay attention to adjustment, so it is hassle-free.
It is also extremely easy to use.
