Abstract

PURPOSE: To prevent a substance to be cooked from being scorched in such a way to decide the power of a heater by a method wherein luminance of a display lamp is controlled according to the thermal power level set at a heater. CONSTITUTION: When a desired thermal power level is inputted to a thermal power setting part 1, a heater 4 is controlled to a desired thermal power according to a thermal power level, inputted to the thermal power setting part 1, by a thermal power control part 2. Luminance of a display lamp 5 is controlled according to the thermal power level inputted to the thermal power setting part 1 by a luminance control part 3. Luminance control is effected in such a manner that luminance of the display lamp 5 is brightened in proportion to the thermal power level with the increase of the thermal power level from a low value to a high value. This constitution decides the power of the heater 4 from luminance of the display lamp 5 and prevents a substance to be cooked from being scorched.

The conventional electric stove is
When using a material that does not emit light even when the heater is energized, the strength of the heat power is determined only by the number of LEDs that are lit, so be accustomed to determining the fire level based on the amount of flame such as gas. It was very difficult for the cooks to use. In addition, although the line of sight when actually cooking is concentrated on the food to be cooked, the conventional electric stove has a display LED on the side surface of the main body, which indicates the strength of the heating power of the heater. In order to confirm the display LED, it is necessary to move the line of sight to the side surface of the main body, and for example, the cooking operation may be stopped.

The present invention has been made in order to solve the above problems, and is provided with a pseudo-flame display lamp whose brightness changes according to the heating power of the heater, and the strength of the heater depends on the brightness of the display lamp. The purpose is to obtain an electric stove that can be judged. Further, even if the line of sight of the cook is concentrated on the food, the display lamp is attached at a position where the change in the brightness of the display lamp can be easily understood while concentrating on the food.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a control block diagram of an electric stove, and FIG. 5 is a diagram showing a change in brightness of a display lamp according to a heating power level.
In the figure, 1 is a heating power setting unit, 2 is a heating power control unit, and 3 is a brightness control unit, and controls the display lamp 5 so that the brightness of the display lamp 5 increases as the heating power level increases.

Next, the operation will be described. As in the conventional case, when the desired thermal power level is input to the thermal power setting unit 1,
The thermal power control unit 2 controls the heater 4 to have a desired thermal power according to the thermal power level input to the thermal power setting unit 1. Further, the brightness control unit 3 controls the brightness of the display lamp 5 as shown in FIG. 5 according to the thermal power level input to the thermal power setting unit 1.
The brightness control is performed so that the brightness of the display lamp 5 becomes brighter in proportion to the heating power level as the heating power level changes from weak to strong.

Example 2. FIG. 2 is a control block diagram showing another embodiment of the present invention. In the first embodiment, the brightness of the display lamp 5 is controlled in accordance with the heating power level signal input from the heating power setting unit 1. However, in the second embodiment, the heater temperature sensor 6 detects the temperature of the heater 4. Then, the brightness of the display lamp 5 is controlled by the brightness controller 3 in accordance with the temperature detected by the heater temperature sensor 6 as shown in FIG. The brightness control is performed so that the brightness of the display lamp 5 becomes brighter in proportion to the detected temperature as the detected temperature of the heater temperature sensor 6 changes from low to high.

Embodiment 3. FIG. 3 is a sectional view of an electric stove showing Embodiment 3 and FIG. 4 is a partial top view of the electric stove. In the figure, 4 is a heater, and 5 is a display lamp, which is provided so as to surround the outside of the heater 4. 6 is a heater temperature sensor, and 7 is a reflector, which reflects the light of the display lamp 5. Reference numeral 8 denotes a heat insulating case, which is a tray shape having a U-shaped cross section in this embodiment, and an insulating material 9 and a heater 4 are provided inside. 10 is a top plate which is made of heat-resistant glass and on which cooking utensils are placed. Reference numeral 11 denotes a reflected light transmitting portion, which is made of transparent glass and is provided on the side surface of the heat insulating case 8. Reference numeral 12 denotes a cooking section, which is located directly above the heater 4. Since the indicator lamp 5 is attached to the outside of the heat insulating case 8, the indicator lamp 5 has a structure that is not easily affected by the heat of the heater 4. Further, since the display lamp 5 arranged so as to surround the outer periphery of the heat insulating case 8 is covered with the reflector 7, the heat insulating case 8, and the top plate 10, the display lamp 5
Light and reflected light are on the top plate 1 above the indicator lamp 5.
Not only can 0 be transmitted and irradiated, but also the cooking part 12 can be irradiated through the reflected light transmitting part 11 as shown by the arrow in FIG. With the above configuration, the strength of the heater 4 during cooking can be recognized by the change in the brightness of the display lamp 5. Further, since the indicator lamp 5 is provided on the outer periphery of the cooking section 12, even when the cook's field of view is concentrated on the food, the strength of the heater can be confirmed by the pseudo flame of the indicator lamp. Furthermore, since the light of the indicator lamp irradiates the cooking section through the transmitting section, the surrounding area of the cooking section and the interior of the cooking section are illuminated over a wide area. Since it is easy to recognize the thermal power state, it is a very convenient device for the cook.

[0017]

As described above, according to the present invention, the brightness of the display lamp is controlled according to the change in the thermal power state even in the electric stove using the heater whose change in the amount of light emission is small even when the power is turned on. The indicator lamp exerts the effect of pseudo flame,
The strength of the heater can be seen from the brightness of the display lamp, and even if you mistakenly start cooking with the heater strong, you can recognize that the heater is strong with the brightness of the display lamp and burn the food. It can be prevented.

Since the brightness of the display lamp changes in accordance with the change in the heat power level of the heat power setting section, the set heat power level is instantly reflected in the change in the brightness of the display lamp, and the temperature can be easily controlled.

Since the brightness of the display lamp changes in accordance with the temperature of the heater, the temperature of the heater can be accurately grasped by the change in the brightness of the display lamp, so that the usability is improved in cooking where the amount of cooking heat greatly affects.

Since the indicator lamp is provided in the vicinity of the heater so that the light of the indicator lamp is radiated to the outside of the housing through the plate, it is possible to confirm the change in the luminance of the indicator lamp from the top surface of the plate when the food is placed on the plate. .
