TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an induction heating device for displaying an output level by a light emitting element when a heating output is operated.
[0002]
[Prior art]
Conventionally, an induction heating device capable of adjusting the level of an output level is provided with a plurality of light emitting elements for displaying the level of the output level, and the number of light emitting elements is changed every time the output level changes, thereby improving visibility and operability. There is something that is raised to improve usability.
[0003]
That is, as shown in FIG. 3, a plurality of light emitting elements 21 whose number of lighting increases or decreases according to the magnitude of the heating output level are arranged at the front upper portion of the induction heating device main body 20, and the output is adjusted on the front surface of the main body 20. The knob 22 is slidably arranged left and right, and the output adjustment knob 22 is slid left and right along the slide groove 22a to increase or decrease the number of light-emitting elements 21 to notify the user of a change in heating output. was there. In addition, 23 is a cooking pot. (For example, Japanese Patent Publication No. 6-65127)
Further, there is a type in which the output adjustment knob 22 is formed into a dial type, and the number of lighting of the light emitting elements is increased or decreased by rotating the dial type output adjustment knob to notify a user of a change in heating output. (For example, JP-A-56-32393, JP-A-11-2412)
In addition, a dial-type output adjustment knob and a plurality of light-emitting elements are provided on the front of the main body, and the number of light-emitting elements is increased or decreased by rotating the dial-type output adjustment knob to notify the user of the change in heating output. There was also. (For example, Japanese Utility Model Publication No. 56-72500)
In recent years, with the aging of the population, an induction heating device using electricity as a heat source instead of a gas stove has been greatly increased, particularly from the viewpoint of safety. This device includes one or more stoves, and further includes a plurality of light emitting elements for indicating the level of the output level for each stove. In many cases, the sound is reported.
[0004]
[Problems to be solved by the invention]
The above-described conventional induction heating apparatus includes a plurality of light emitting elements as described above to improve the usability. However, unlike a gas stove, the intensity of the heating power (output) cannot be visually confirmed. There is a problem that it is difficult to understand the image of the gas, such as low heat, medium heat, high heat, etc., by simply increasing or decreasing the number of lighting of the elements, and it is difficult to understand the strength of the thermal power.
[0005]
As shown in FIG. 3, since the number of lighting of the light emitting elements 21 is increased or decreased by sliding the lever-type output adjusting knob 22 to the left or right, a multi-stage output display by a plurality of light emitting elements 21 is performed. If the number of the elements 21 is not counted, the magnitude of the output is difficult to understand, and the magnitude of the output is difficult to understand how much heating power is in gas fire.
[0006]
Further, there is a drawback that cleaning is difficult when oil and the like during cooking adhere to the unevenness of the output adjustment knob 22 and the slide groove 22a for guiding the output adjustment knob 22.
[0007]
Further, in the case where the output adjustment knob is set to a dial type and the number of lighting of the light emitting element is increased or decreased by rotating the dial type output adjustment knob, the operation is difficult because the position of the output adjustment knob and the light emitting element are separated. There was a disadvantage.
[0008]
Also, as in the former case, since the output is displayed in multiple stages using a plurality of light-emitting elements, it is difficult to understand the magnitude of the output unless the number of light-emitting elements is counted. There was a drawback that it was difficult to tell if it was thermal power.
[0009]
Further, there is a drawback that cleaning is difficult when oil or the like during cooking adheres to the unevenness of the output adjustment knob or the groove around the output adjustment knob.
[0010]
[Means for Solving the Problems]
The present invention has been made to solve the above-described problems, and specifically, includes a plurality of light emitting elements whose number of lighting increases or decreases according to the level of the output level at the front part of the upper surface of the main body, and the light emitting element has an output level. Each of the heat power indicators is arranged so as to face the classified light emitting element, and is also used as a switch for changing the lighting number of the classified light emitting element.
[0011]
Further, the switch is constituted by a sheet key switch.
[0012]
Accordingly, since there is a switch of the heat power indicator near the light emitting element, the output adjustment operation is easy.
[0013]
In addition, it is possible to easily adjust the degree of fire, which is the same as the convenience of using a gas stove, and it is easy to use, and the adjustment within the standard of the thermal power can be set finely.
[0014]
Further, compared to lever-type or rotary-type adjustment knobs, the thermal power does not greatly change due to erroneous operation, and it is easy to use.
[0015]
Further, since the switch for the thermal power is flat, even if oil or the like adheres during cooking, cleaning is easy.
[0016]

[0018]
In the figure, reference numeral 1 denotes a main body of the induction heating device, and 2 denotes a food placing table which constitutes an upper surface of the main body 1, on which an induction heating coil (not shown) is installed. Reference numeral 3 denotes a pot placed on the upper surface of the food placing table 2, which is heated by the induction heating coil. Reference numeral 4 denotes a power switch provided on the front right side of the main body 1. Reference numeral 5 denotes an on / off key provided on the front left side of the main body 1. After the power switch 4 is turned on, pressing the on / off key 5 causes heating. Begin.
[0019]
Reference numeral 7 denotes an output display unit arranged at the front of the upper surface of the main body 1. As shown in FIG. 2, a heating output level 8 indicated by numerals from 1 to 11 and each of the output levels 8 The light-emitting element 9 is provided below the light-emitting element 9 and the reference value 10 is displayed below the light-emitting element 9.
[0020]
When the output power level 8 is 1 stage, the heat level 10 is a low heat 10a, a low heat 10b from 2 to 4 stages, a medium heat 10c from 5 to 7 stages, a high heat 10d from 8 to 10 stages, and a high fire 10d from 8 to 10 stages, and 11 stages. It is divided into high power 10e and five classification groups, and is displayed in an expression according to the heating power of the gas stove which is easy to be used by the user for many years.
[0021]
In addition, the five classification groups of the heating power guide 10, which are the low heat 10a, the low heat 10b, the medium heat 10c, the high heat 10d, and the high power 10e, also serve as switches for changing the number of lighting of the classified light emitting elements 9. . This switch is composed of a sheet key switch, and is electrically connected to the light emitting element 9 and a control unit (not shown) in the main body 1.
[0022]
Reference numeral 11 denotes a sound generator incorporated in the main body 1. In this embodiment, the boundary of the five classification groups of the low heat 10a, the low heat 10b, the medium heat 10c, the high heat 10d, and the high power 10e of the above-described heat power indicator 10 is defined by the light emitting element 9. A sound is emitted when the number of lights of moves.
[0023]
Further, as described above, the sounding body 11 can emit a different sound when the lighting number of the light emitting element 9 moves on the boundary of the classification group of the thermal power guide 10 as described above.
[0024]
Further, the output level at the start of heating, that is, the seven stages may be set to the output used for the most dishes, and a sound may be emitted only at the start of heating and when the light-emitting element 9 moves its output.
[0025]
In the above configuration, the user places the pot 3 on the food placing table 2 of the main body 1, turns on the power switch 4, and then presses the on / off key 5 to start heating.
[0026]
After that, one of the switches of the low heat 10a, the low heat 10b, the medium heat 10c, the high heat 10d and the high power 10e of the heat power reference 10 is pressed to adjust the output level (heat control).
[0027]
Now, when it is desired to set the output level 8 to the seventh stage of the medium heat 10c and start the heating, when the switch of the medium heat 10c is pressed, the light emitting element 9 is set to the output level 8 as shown in FIG. Lighting is sequentially performed from the stage to the seventh stage to start heating.
[0028]
Next, when it is desired to switch the output level 8 from any of the eight levels of the high heat 10d to the ten levels, the switches of the high heat 10d are sequentially pressed, and the boundary of the classification group of the medium heat 10c to the high heat 10d of the thermal power reference 10 is obtained. The number of lighting of the light emitting element 9 moves. At this time, the sounding body 11 emits a sound to notify the user that the medium heat 10c has shifted to the high heat 10d. Then, the light-emitting element 9 is turned on when the output level 8 is within the range of 8 to 10 levels in the high-fire 10d group. Note that no sound is emitted when the number of lights increases or decreases within the high flame 10d.
[0029]
Conversely, when the heat power reference 10 is changed from the medium heat 10c to the low heat 10b and further to the low heat 10a, the switch is pressed to light the light emitting elements 9 of each classification group. At this time, when the lighting number of the light emitting element 9 moves on the boundary of each classification group, the sounding body 11 emits a sound, and informs the user that it has shifted to the low heat 10b and the low heat 10a. Then, no sound is emitted when the number of lights increases or decreases in the output level 8 from seven levels to five levels of the medium heat 10c and four levels to two levels of the low heat 10b in each classification group.
[0030]
In the adjustment of the heating power reference 10, when the output level 8 is set to the seventh step of the medium heat 10c, in the above embodiment, the light emitting elements 9 are sequentially turned on from the first step to the seventh step of the output level 8. However, this is not always necessary, and the lighting may be performed only in the light emitting element 9 in the fifth to seventh steps of the output level 8.
[0031]
The same applies to the case of the low heat 10a, low heat 10b, medium heat 10c, high heat 10d and high power 10e.
[0032]
Further, the thermal power reference 10 does not necessarily need to be divided into five classification groups, and for example, the high heat 10d and the high power 10e may be one.
[0033]
Further, the sounding body 11 may emit a different tone when the number of lighting of the light emitting elements 9 moves on the boundary of the classification group of the thermal power guide 10.
[0034]
Further, the output level at the start of heating, that is, the seven stages of medium heat 10c is set as the output used for the most dishes, and a sound is emitted only at the start of heating and when the lighting of the light emitting element 9 moves the output. It may be.
[0035]
As described above, the user can easily heat and cook at the desired output level 8 by pressing the switch of the heat reference 10 in the classification group of the low heat 10a, the low heat 10b, the medium heat 10c, and the high heat 10d of the heat reference 10. Can be.
[0036]
In addition, since there is a switch of the thermal power indication 10 near the light emitting element 9 by this, the output adjustment operation is easy.
[0037]
In addition, it is possible to easily adjust the degree of fire similar to the convenience of using the gas stove, to facilitate the use, and to finely set the adjustment within the reference value of the thermal power 10.
[0038]
Further, compared to lever-type or rotary-type adjustment knobs, the thermal power does not greatly change due to erroneous operation, and it is easy to use.
[0039]
Further, since the switch of the thermal power reference 10 is flat, even if oil or the like adheres during cooking, cleaning is easy.
[0040]
With the above configuration, even when a gas stove is replaced with an induction heating device, the output can be easily adjusted and the induction heating device can be used easily, similarly to a gas stove which is easily used and used for many years.
