Abstract

PURPOSE:To facilitate watching of a display part, by a method wherein a control state is outputted to a display means to change over the graduation of display of a control state, outputting a display content, by means of a mode changed over by a control mode switching means. CONSTITUTION:It is decided by a control mode switching means 13 by means of an input from a change-over switch 21 whether the control mode of a control means 12 is a power control mode or a temperature regulation control mode, and the control system of a control means 12 is switched. A liquid crystal drive means 16 displays it in a control state display ares 101 of an LCD 15 according to information on a control state by the control means 12. When a control mode is a power control mode and a power is set to, for example, high, all blocks are lighted ON, and when a power is set to '4', all five blocks from the left are lighted ON. Meanwhile, when a control mode is a temperature regulation mode and a set temperature is 14 deg.C, a third block from the left is lighted ON, and the rest is lighted OFF. During the power control mode, a power graduation 102 is lighted ON by a graduation display switching means 17, and a temperature graduation 103 is lighted OFF. Meanwhile, during the temperature regulation mode, the temperature graduation 103 is lighted ON and the power graduation 102 is lighted OFF.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric range used as kitchen equipment in ordinary households.

2. Description of the Related Art As shown in FIG. 4(a), a conventional electric range of this type uses light emitting diodes 1 to 6 to indicate the power control status using bars, and a scale printed near these light emitting diodes. was used to read the power control status. In addition, in the temperature adjustment control mode, the set temperature is as shown in Figure 4 (b).
), setting 2 was performed based on the position of the dial knob 7 and the scale printed around it.

Problems to be Solved by the Invention In such a conventional configuration, a scale is printed in advance, and the light emitting diodes 1 to 1 corresponding to the printed scale are
Since the setting status is displayed by lighting the dial knob 6 or by changing the position of the dial knob 7, it is difficult to see the print and make settings in a dark place. In addition, there are two modes: power control mode and temperature adjustment control mode.
Two types of display mechanisms are required; in this case, the power control mode scale is visible even in temperature adjustment control mode, so a display device is required to display which control mode is currently set. It had problems such as:

The present invention solves the above-mentioned problems, and allows the output display section in the power control mode and the set temperature display section in the temperature adjustment control mode to be shared and displayed on one display device. The purpose of the present invention is to provide an electric range that can display the currently set control mode by exclusively displaying the corresponding scale display, and that has an easy-to-read and clear display section. It is.

Means for Solving the Problems In order to achieve the above objects, the electric range of the present invention includes a heating means that completely heats the heater, a control means that controls this heating means, and a control mode of this control means that is set to a power control mode. a control mode switching means for switching to one of the temperature adjustment control modes; a display means comprising a liquid crystal display element;
temperature detection means for detecting the temperature of the bottom of the pot when the control means is in a temperature adjustment control mode; a liquid crystal display and driving means for displaying the control state of the control means on a display means; The display device is equipped with a scale display switching means for switching all the scales of the display means.

Operation According to the above configuration, the liquid crystal driving means outputs the control state performed by the control means to the display means, and the scale display switching means outputs the display contents according to the mode switched by the control mode switching means. Since the entire scale of the display can be switched, the display section is easy to see and neat.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of an electric range according to an embodiment of the present invention, in which 11 is a heating means for heating the heater by energizing it, 12 is a control means for controlling the heating means 11, and 13 is a control means. 12 is a control mode switching means for switching the control mode between the power control mode and a temperature adjustment control mode in which the temperature is controlled using the temperature detection means 14 as an input; 15 is a display for displaying all the control states performed by the control means 12; It is constituted by a liquid crystal display element (hereinafter referred to as LCD). 16 is a liquid crystal driving means for driving the display means 16; 17 is a scale display switching means for switching the scale of the control state displayed on the display means 16 according to the control mode selected by the control mode switching means 13;

FIG. 2 shows a circuit diagram of the electric range. Reference numeral 18 is an AC power source, and the heating means 11 is composed of a heater 19, a relay contact 20&, and a relay coil 20b. Since the relay coil 20b is energized and controlled by the control means 12, the relay contacts 20& are controlled to open and close. As a result, current flows from the AC power supply 18 to the heater 19, so that the heater 19 is controlled to be energized and heated. Further, the control mode switching means 13 determines the control mode of the control means 12 as power control mode or temperature adjustment control mode based on the input from the changeover switch 21, and switches the control method of the control means 12, for example, the power control mode. In the control mode, the control means 12 controls the duty of the relay coil 20b"i according to the electric power set by the changeover switch 21, and controls the energization of the heater 19. On the other hand, in the temperature adjustment control mode, the thermistor is activated in the temperature detection means 14. 22 detects the temperature of the bottom of the pot placed on the heater 19 until the temperature reaches the temperature set by the changeover switch 21.

The relay coil 20b is energized, and when the temperature reaches the set temperature or higher, the energization to the relay coil 20b is stopped. In the liquid crystal drive means 16, the third
These are displayed in the control status display area 101 of the LCD 1s shown in the figure. When the control mode is the power control mode, for example, when the power setting is high, all of them light up, and when the power setting is "4", 6 from the left are all lit.

On the other hand, when the control mode is the temperature adjustment mode, for example, when the set temperature is set to 140°C, the third block from the left is lit and the remaining blocks are turned off. Further, reference numerals 0102 and 103 in FIG. 3 are scales in the control status display area 101 that displays the control status described above, and the power scale 102 lights up in the power control mode by the scale display switching means 1 in FIG. 2, and the temperature scale 103 goes out. On the other hand, in the temperature adjustment control mode, the temperature scale is 10.
3 lights up, and the power scale 102 goes out.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Since it is equipped with a scale display switching means that switches the scale of the display means according to the mode switching of the control mode switching means, the control state display during power control mode and the control state display during temperature adjustment mode control are displayed in the same control state display area. The temperature control status can be displayed, and the scale display is exclusively displayed, so
You can see at a glance which mode the current mode is set to, and as a result, there is no need to display the currently set mode, so it has a very clean design. This has practical effects such as the ability to obtain.
