Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a household hot plate.

BACKGROUND OF THE INVENTION Conventional hot plate control devices control energization of heaters embedded in the plate based on the set control temperature when the user sets one of the control temperatures of a plurality of plates. It was common to control the temperature of the plate.

Problems to be Solved by the Invention With such conventional hot plate control devices, the temperature is controlled using only one preset control temperature. The problem was that the control temperature had to be changed, making it inconvenient to use.

In view of the above problems, the present invention notifies the user of the end of cooking, and then automatically changes the control temperature of the plate.
The purpose is to improve usability.

Means for Solving the Problems In order to solve the above problems, the present invention provides a heater embedded in a plate for heating food, a temperature sensor for measuring the temperature of the plate, and a control temperature setting for the plate. a temperature setting means for notifying the user; a storage means for storing a control process of the hot plate; is set, and when the control temperature is reached, it is output to the notification means, and then the temperature of the plate is lowered to a predetermined temperature by energizing with constant electric power.
Thereafter, when the temperature rises to a predetermined temperature, the control means outputs an output to the notification means and controls the set temperature of the plate to be automatically changed.

Function: With the above-described configuration, the present invention performs a predetermined setting and notifies the user when the temperature of the plate reaches the preset control temperature, thereby notifying the user that food is to be added. When the plate temperature drops to a predetermined temperature by placing food on the plate, and then rises to a predetermined temperature, the notification means notifies the completion of the food, and at the same time automatically changes the set control temperature. control.

Embodiment FIG. 1 is a block diagram showing an embodiment of the hot plate control device of the present invention. In FIG. 1, 1 is a temperature setting means for setting the control temperature of the plate, 2 is a heater embedded in the plate that heats the food to be cooked, 3 is a temperature sensor that measures the temperature of the plate, and 4 is the start and end of cooking. 6 is a storage means for storing the control stroke of the plate; 6 is a storage means for storing a control stroke of the plate; and 6 is a storage means for outputting an output to the notification means 4 when a predetermined setting is made by the temperature setting means 1 and the control temperature is reached. Thereafter, when the temperature of the plate drops to a predetermined temperature despite the constant power supply and then rises to a predetermined temperature, an output is sent to the notification means 4 and the set temperature is changed. It is a control means.

FIG. 2 is a circuit diagram showing a specific configuration of an embodiment of the hot plate control device of the present invention. In Figure 2, 1
1 is a temperature setting switch that sets the control temperature of the plate;
12P'i is a heater embedded in the plate that heats the food; 15 is a temperature sensor that measures the temperature of the plate;
16 is a Mu/D converter that converts the output of the temperature sensor 16 into Mu/D; 17 is a buzzer that notifies the start and end of cooking; 13 is a relay that energizes the heater 12; and 14 is a device that drives the relay 13. relay drive unit, 18
is an input section 181L that inputs the outputs of the temperature setting switch 11 and the M/D converter 16, a storage section 180 that stores the control stroke of the hot plate, and outputs to the relay drive section 14 and the buzzer 17. The output section 18d performs
Then, a predetermined setting is made by the temperature setting switch 11, and when the control temperature is reached, the buzzer 17 is output, and after that, the temperature of the plate reaches the predetermined temperature even though electricity is supplied with constant power. The microcomputer is equipped with a control section 18b that outputs an output to the buzzer 17 when the temperature drops and then rises to a predetermined temperature, and controls the set temperature to be changed.

Next, the operation of the microcomputer 18 will be explained.

FIG. 3 shows the main part of the 70-chart of the microcomputer 18. Step 21 in Figure 3
Then, the temperature setting key 11 is inputted, and in step 22 it is determined whether or not the temperature setting key 11 has been inputted. If there is no input, the process goes to step 24. If the key is available, the hot plate is turned off in step 23. Soften the control temperature by one and return to step 21. In step 24, it is determined whether the input of the temperature setting key 11 has been completed, and if it has not been completed, the process returns to step 21. When the process is completed, in step 25, the set control temperature determines whether the auto menu (control process point for automatic cooking) has been selected;
If Auto Menu is not selected, step 26
to control the temperature of a regular hot plate. If it has been selected, input to the temperature sensor 16 is performed in step 27. In step 28, it is determined whether the first temperature control point (set temperature) has been passed, and if it has not passed, power is output in step 35. If passed, step 2
At step 9, it is determined whether or not the buzzer 17 has sounded, and if it has not sounded, the buzzer 17 is sounded at step 30 to notify that cooking can be started. If the buzzer 17 sounds in step 29, it is determined in step 31 whether the second temperature control point (temperature below the set temperature) has been passed, and if it has not passed, constant power is applied to the heater 12 in step 35. do. If it has passed, it is determined in step 32 whether the third temperature control point (temperature equal to or higher than the set temperature) has been passed, and if it has not passed, constant power is continued to be supplied to the heater 12 in step 36. If it has passed, in step 33 the setting point is switched from the auto menu to the low temperature control point of the normal hot plate. Next, in step 34, the buzzer 17 is sounded to notify that the auto menu has ended. In step 36, the heater 12 is energized with thermal power at the controlled temperature at that time. After step 36, return to step 21, and from step 21 to step 3.
Repeat step 6. The temperature control points have a relationship of first temperature control point≧third temperature control point≧second temperature control point.

Effects of the Invention As is clear from the above examples, the present invention has the following effects.

(1) Since the time to start cooking can be easily determined and the time to finish cooking is notified, there is no need to check the cooking status during cooking, which improves usability.

(If you change the control temperature to a low temperature after completing 2 cooking, you can keep the food warm without burning it.
