Description

【0001】
【発明の属する技術分野】
本発明は、誘導加熱装置の出力操作時に出力レベルを音と発光素子によって報知する報知機構に関するものである。
【0002】
【従来の技術】
従来、出力レベルの大小を調節できる誘導加熱装置において、出力レベルの大小を表示する複数の発光素子と、この発光素子の出力レベルの大小に応じて音を発する発音体とを備え、発光素子の点灯数が変化する毎に音を発して視認性、操作性を上げ、使い勝手を向上させるようにしたものがある。
【0003】
すなわち、図3に示すように、出力表示部20を例えば1から11段階までの数字で表された出力レベル21と、この出力レベル21の夫々の数字に対応してその下部に設けられた発光素子22とで構成し、出力調節ツマミ(図示せず)を左右に回すと、出力レベル21の数字と発光素子22が1個づつ変わる毎に発音体23から単一音を発してユーザーに出力変化を報知していた。(特公平6−65127号公報)
また、出力レベルの大小を表示する複数の発光素子と報知手段とを備え、加熱の開始時のみ報知手段を鳴動させるものもあった。(実開昭59−139997号公報)
さらに、実開昭56−72500号公報に示すように、加熱出力の各設定値に対応して複数個の発光素子を設けたり、実開昭55−47193号公報に示すように、電力設定手段で設定したレベルに応じて出力レベルを表示する表示素子を備えたものもあった。
【0004】
近年では、高齢化に伴い、特に安全性の点からガスコンロに代わって電気を熱源とする誘導加熱装置が大きく伸びてきている。この装置には1個または複数個のコンロ部を備えており、さらに、個々のコンロ部に対して出力レベルの大小を表示する複数個の発光素子を備えて、この発光素子の点灯数の増減に伴い音を報知しているものが多い。
【0005】
【発明が解決しようとする課題】
上記従来の誘導加熱装置においては、使い勝手をさらに良くするために上記したように発光素子や発音体を備えているが、ガスコンロとは違って火力(出力)の強さを目で確認できないため、発光素子の点灯数の増減に伴って報知音を鳴動させるだけではガスの弱火や中火、強火等のイメージがわかりにくく、火力の強さがわかりにくいという問題があった。
【0006】
【課題を解決するための手段】
本発明は、上記課題を解決するものであり、具体的には、出力レベルを複数段階調節可能な誘導加熱コイルと、これら出力レベルの段階に対応して設けられ、出力レベルの段階に応じて点灯数が増減される数の発光素子と前記出力レベルが変化したときに音を発する発音体とを備え、前記出力レベルは複数の前記出力レベルの段階からなるグループに分けられていて、前記誘導加熱コイルの出力レベルの段階が設定される際、異なる前記グループの出力レベルの段階に設定されるときには、前記発光素子の点灯数が増減されるとともに前記発音体は音を発し、前記グループ内で異なる出力レベルの段階が設定されるときには、前記発光素子の点灯数が増減され前記発音体は音を発しないようにしたものである。
【0007】
また、発音体は、誘導加熱コイルの出力レベルの段階が設定される際に、前記グループの一つである強火グループと該強火グループよりも出力レベルの低い段階の中火グループとの間と、この中火グループと該中火グループよりも出力レベルの低い段階の弱火グループとの間で、設定される出力レベルの段階が変わるときに音を発するようにしたものである。
【0008】
上記のように、出力レベルを火力目安ごとに分類し、かつ、その分類された火力目安を本体の上面前部に表示することにより、ガスコンロの使い勝手と同様の火加減が簡単に調節でき、使いやすい誘導加熱装置とすることができる。
【0009】
【発明の実施の形態】
以下、本発明の一実施例を図面中の図1及び図2に従って説明する。
【0010】
図1は本発明の誘導加熱装置の斜視説明図、図2はその出力レベルと発光素子部出力表示部の説明図である。
【0011】
1は誘導加熱装置の本体、2は本体1の上面を構成する食品載置台で、その下面に誘導加熱コイル(図示せず)が設置されている。3は食品載置台2の上面に載置された鍋で、前記誘導加熱コイルにより加熱される。4は本体1の前面右側に設けられた電源スイッチ、5は本体1の前面左側に設けられた入/切キーで、電源スイッチ4を入れた後、この入/切キー5を押すと加熱が始まる。6は出力レベル(火加減)を調節する出力調節ツマミで、電源スイッチ4と入/切スイッチ5の間に設けられ、右に回すと出力レベルが大きくなり(火力が強くなる)左に回すと出力レベルが小さくなる(火力が弱くなる)。
【0012】
7は本体1の上面前部に配置された出力表示部で、図2に示すように、1から11段階までの数字で表された加熱の出力レベル8と、この出力レベル8の夫々の数字に対応してその下部に設けられた発光素子9及びこの発光素子9の下部に表示された火力目安10とで構成されている。
【0013】
火力目安10は、出力レベル8が1段階ではとろ火10a、2段階から4段階までは弱火10b、5段階から7段階までは中火10c、8段階から10段階までは強火10d、そして11段階ではハイパワー10eと5つの分類グループに分かれており、使用者に長年の使用で馴染みやすいガスコンロの火力にあわせた表現で表示されている。
【0014】
11は本体1内に組み込まれた発音体で、本実施例では、上記火力目安10、すなわち、とろ火10a、弱火10b、中火10c、強火10d及びハイパワー10eの5つの分類グループの境界をこえて発光素子9の点灯数が増減するときに音を発するようになっている。
【0015】
また、この発音体11は、上記のように火力目安10の分類グループの境界をこえて発光素子9の点灯数が増減するときに異なった音を発することができる。
【0016】
また、発光素子9の点灯数が最大に達したときと最小に達したとき及び最大以上と最小以下の出力設定を行ったときにも異なった音を発することができる。
【0017】
さらに、加熱開始時の出力レベル、すなわち7段階を最も多くの料理に使用する出力とし、この加熱開始のとき及び発光素子9の点灯がその出力から変わるときのみ音を発することもできる。
【0018】
上記の構成において、使用者が本体1の食品載置台2上に鍋3を載置し、電源スイッチ4を入れた後、入/切キー5を押して加熱を開始する。
【0019】
その後、出力調節ツマミ6を操作して出力レベル(火加減)を調節する。右に回すと出力レベルが大きくなり(火力が強くなる)左に回すと出力レベルが小さくなる(火力が弱くなる)。
【0020】
今、出力レベル8を7段階目の中火10cで加熱を開始したのち、強火10dに切り替えたい場合には出力調節ツマミ6を右に回すと、火力目安10の中火10cから強火10dの分類グループの境界をこえて発光素子9の点灯数が増加する。このときに発音体11は音を発し、中火10cから強火10dに移ったことを使用者に知らせる。そして、強火10dグループ内で出力レベル8が8段階から10段階で点灯数が増減するときには音は発しない。
【0021】
逆に、出力ツマミ6を左に回して火力目安10を中火10cから弱火10b、さらにはとろ火10aにした場合には、各分類グループの境界をこえて発光素子9の点灯数が減少するときに発音体11は音を発し、弱火10b、とろ火10aに移ったことを使用者に知らせる。そして、各分類グループ内で出力レベル8が中火10cの7段階から5段階及び弱火10bの4段階から2段階に点灯数が増減するときには音は発しない。
【0022】
上記の火力目安10の調節において、発音体11は、火力目安10の分類グループの境界をこえて発光素子9の点灯数が増減するときに異なった音色を発するようにしてもよい。
【0023】
また、発光素子9の点灯数が最大に達したときと最小に達したとき及び最大以上、最小以下の出力設定を行ったときにも異なった音色を発してもよい。
【0024】
さらに、加熱開始時の出力レベル、すなわち中火10cの7段階を最も多くの料理に使用する出力とし、この加熱開始のとき及び発光素子9の点灯がその出力をこえるときのみ音を発するようにしてもよい。
【0025】
さらに、火力が最小以下、最大以上に調節を行ったときは、さらに異なった音を発して火力がそれ以上可変できないことを促すようにしてもよい。
【0026】
このように、使用者は火力目安10のとろ火10a、弱火10b、中火10c、強火10dの分類グループ内での点灯数増減では音を発しないようにし、分類グループ間をこえて増減する場合には音を発して火力の大きさが変わったことを促すため、火力目安の境界が非常にわかりやすいものである。
【0027】
なお、火力目安10のハイパワー10eは、強火10dまでの表示の場合にはなくても良い。
【0028】
上記の構成により、ガスコンロから誘導加熱装置に買い換えた場合でも、長年使用して馴染みやすいガスコンロ同様に出力調節が簡単にでき、使いやすい誘導加熱装置とすることができる。
【0031】
【発明の効果】
以上説明したように、本発明によれば、長年使用して馴染みやすいガスコンロの使い勝手と同様の火加減が簡単に調節でき、使いやすい誘導加熱装置とすることができる。
【0032】
また、この出力が変わるときに音を変えること等により火力目安の境界がさらに分かり易くなるものである。

Conventionally, an induction heating apparatus capable of adjusting the level of an output level includes a plurality of light emitting elements that display the level of the output level, and a sounding body that emits sound according to the level of the output level of the light emitting element. There is one that emits a sound every time the number of lights changes, improving visibility and operability, and improving usability.
[0003]
That is, as shown in FIG. 3, the output display unit 20 has an output level 21 represented by numbers from 1 to 11, for example, and light emission provided below the output level 21 corresponding to each number of the output level 21. When the output adjustment knob (not shown) is turned to the left or right, a single sound is emitted from the sound generator 23 and output to the user each time the number of the output level 21 and the light emitting element 22 change one by one. I was informed of the change. (Japanese Patent Publication No. 6-65127)
In addition, there are some which include a plurality of light emitting elements that display the magnitude of the output level and an informing means, and cause the informing means to ring only at the start of heating. (Japanese Utility Model Publication No. 59-139997)
Further, as shown in Japanese Utility Model Laid-Open No. 56-72500, a plurality of light-emitting elements are provided corresponding to each set value of the heating output, or as shown in Japanese Utility Model Laid-Open No. 55-47193, power setting means is provided. Some have a display element that displays an output level in accordance with the level set in (1).
[0004]
In recent years, with the aging, induction heating devices that use electricity as a heat source instead of a gas stove are growing greatly from the viewpoint of safety. This apparatus is provided with one or a plurality of stove sections, and further includes a plurality of light emitting elements for displaying the magnitude of the output level for each stove section. Many of them are reporting sound.
[0005]
[Problems to be solved by the invention]
In the conventional induction heating device, in order to further improve the usability, the light emitting element and the sounding body are provided as described above, but unlike the gas stove, the strength of the thermal power (output) cannot be visually confirmed, There is a problem in that it is difficult to understand the image of low, medium, and high heats of gas simply by sounding a notification sound as the number of light emitting elements is turned on and off, and it is difficult to understand the strength of the thermal power.
[0006]
[Means for Solving the Problems]
The present invention is intended to solve the above problems, specifically, a plurality of steps adjustable induction heating coil output level, provided corresponding to these output level stages, depending on the stage of the output level and multiple light-emitting element number lighting is increased or decreased, and a sounding body that emits a sound when the output level is changed, the output level is not divided into groups of a plurality of stages of the output level When the output level stage of the induction heating coil is set, when the output level stage of the different group is set, the number of lighting of the light emitting elements is increased and decreased, and the sounding body emits a sound, When different output level stages are set in the group, the number of lighting of the light emitting elements is increased or decreased so that the sound generator does not emit sound .
[0007]
In addition, the sounding body, when the stage of the output level of the induction heating coil is set, between a high-fire group that is one of the groups and a medium-fire group that is at a lower output level than the high-fire group, A sound is generated when the level of the set output level changes between the medium-fire group and the low-fire group at a lower output level than the medium-fire group .
[0008]
As described above, by classifying the output level for each thermal power standard and displaying the classified thermal power standard on the front of the top surface of the main unit, it is possible to easily adjust the heating level similar to the convenience of the gas stove. It can be an easy induction heating device.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 in the drawings.
[0010]

[0011]
Reference numeral 1 denotes a main body of the induction heating apparatus, and 2 denotes a food placing table that constitutes the upper surface of the main body 1, and an induction heating coil (not shown) is installed on the lower surface thereof. 3 is a pan placed on the upper surface of the food placing table 2 and is heated by the induction heating coil. 4 is a power switch provided on the front right side of the main body 1, and 5 is an on / off key provided on the left side of the front surface of the main body 1. After the power switch 4 is turned on, pressing this on / off key 5 causes heating. Begins. 6 is an output adjustment knob that adjusts the output level (fire control), and is provided between the power switch 4 and the on / off switch 5. When turned to the right, the output level increases (fire power increases) and to the left The output level becomes small (fire power becomes weak).
[0012]
Reference numeral 7 denotes an output display unit arranged at the front surface of the upper surface of the main body 1. As shown in FIG. 2, the heating output level 8 represented by numbers from 1 to 11 and the numbers of the output level 8 are shown. Corresponding to the light emitting element 9 provided in the lower part thereof and the thermal power standard 10 displayed in the lower part of the light emitting element 9.
[0013]
The firepower standard 10 is that when the output level 8 is 1 stage, the low fire 10a is obtained from the 2nd stage to the 4th stage, the low fire 10b, from the 5th stage to the 7th stage, the medium fire 10c, from the 8th stage to the 10th stage, the high fire 10d, and at the 11th stage. It is divided into high power 10e and five classification groups, and is displayed in an expression that matches the firepower of a gas stove that is familiar to the user over many years of use.
[0014]
Reference numeral 11 denotes a sounding body incorporated in the main body 1. In this embodiment, the thermal power standard 10 is exceeded, that is, the boundaries of the five classification groups of the hot fire 10a, the low fire 10b, the medium fire 10c, the high fire 10d, and the high power 10e. number lighting of the light emitting element 9 is adapted to emit a sound when the increase or decrease Te.
[0015]
Further, the sounding body 11 can emit different sounds when the number of lighting elements 9 increases or decreases beyond the boundary of the classification group of the thermal power standard 10 as described above.
[0016]
Also, different sounds can be emitted when the number of lighting of the light emitting elements 9 reaches the maximum and minimum, and when the output setting is set to the maximum and minimum.
[0017]
Furthermore, an output level at the start of heating, that is, an output that uses seven stages for the most dishes, and a sound can be emitted only at the start of heating and when the lighting of the light emitting element 9 changes from the output.
[0018]
In the above configuration, the user places the pan 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.
[0019]
Thereafter, the output adjustment knob 6 is operated to adjust the output level (fire level). Turning it to the right increases the output level (increases the thermal power), and turning it to the left decreases the output level (decreasing the thermal power).
[0020]
If you want to switch to the high fire 10d after starting the heating at the output level 8 at the 7th medium heat 10c, turn the output control knob 6 to the right to classify the fire level 10 from the medium fire 10c to the high fire 10d. The number of lighting of the light emitting element 9 increases beyond the group boundary. At this time, the sounding body 11 emits a sound to inform the user that the medium fire 10c has shifted to the high fire 10d. No sound is emitted when the number of lights increases or decreases in the high fire 10d group when the output level 8 is 8 to 10.
[0021]
On the contrary, when the output knob 6 is turned counterclockwise to change the fire power guide 10 from the medium fire 10c to the low fire 10b, and further to the fire 10a, when the number of lighting of the light emitting elements 9 decreases beyond the boundary of each classification group The sounding body 11 emits a sound to inform the user that it has moved to the low heat 10b and the low heat 10a. In each classification group, no sound is emitted when the number of lighting levels increases or decreases from the seventh level of the medium fire 10c to the fifth level and from the fourth level of the low heat 10b to the second level.
[0022]
In the adjustment of the thermal power guideline 10 described above, the sounding body 11 may emit a different tone when the number of lighting elements 9 increases or decreases beyond the boundary of the classification group of the thermal power guideline 10.
[0023]
Also, different timbres may be emitted when the number of lighting elements 9 has reached the maximum, when it reaches the minimum, and when the output setting is greater than or less than the maximum.
[0024]
Furthermore, the output level at the start of heating, that is, the output that uses the seven stages of the medium flame 10c for the most dishes is used, and a sound is emitted only at the start of heating and when the lighting of the light emitting element 9 exceeds the output. May be.
[0025]
Furthermore, when the heating power is adjusted below the minimum and above the maximum, a different sound may be emitted to encourage that the heating power cannot be changed any more.
[0026]
In this way, when the user increases or decreases the number of lighting within the classification groups of the hot fire 10a, the low fire 10b, the medium fire 10c, and the high fire 10d of the firepower standard 10, and increases or decreases between the classification groups. Because it emits sound and encourages the magnitude of the firepower to change, the boundary of the firepower guideline is very easy to understand.
[0027]
Note that the high power 10e of the firepower standard 10 may not be required in the case of displaying up to the high fire 10d.
[0028]
With the above configuration, even when a gas stove is replaced with an induction heating device, the output can be easily adjusted in the same manner as a gas stove that has been used for many years and is easy to get used to.
[0031]
【The invention's effect】
As described above, according to the present invention, it is possible to easily adjust the amount of fire similar to the convenience of a gas stove that has been used for many years and is easy to use, and it is possible to provide an easy-to-use induction heating apparatus.
[0032]
Further, by changing the sound when this output changes, it becomes easier to understand the boundary of the thermal power standard.
