JP-A-10-290747

しかしながら、上述したような炊飯器では、ちょっとしたはずみで火力調節レバー１３に触れただけで火力調節位置が変わり易く、常に同じ火力調節位置で同一炊飯することが難しいという問題があった。
特に、飲食店等で使用される業務用の炊飯器では、同一量で同一品質のご飯を何回も炊く必要があるため、一旦決めた火力が変化してしまうことは大きな問題となっていた。
本発明は上記課題を解決し、一旦決めた火力がずれることのない炊飯器を提供することを目的とする。 However, in the rice cooker as described above, there is a problem that it is difficult to change the heating power adjustment position simply by touching the heating power adjustment lever 13 with a slight momentum, and it is difficult to always cook the same rice at the same heating power adjustment position.
In particular, in a commercial rice cooker used in restaurants, etc., it is necessary to cook the same amount of rice with the same amount many times, so it has been a big problem that the heating power once determined changes. .
This invention solves the said subject and aims at providing the rice cooker which the thermal power once decided does not shift | deviate.

上記課題を解決する本発明の請求項１記載の炊飯器は、
炊飯量に応じて火力を調節する火力調節レバーの設定操作に連動してバーナへの燃料ガス供給量を調節する火力調節手段を備えた炊飯器において、

For this reason, even if the thermal power adjustment lever is accidentally touched, the thermal power adjustment lever does not move, and rice can always be cooked in a desired state.

また、本発明の請求項２記載の炊飯器は、火力調節レバーが動くスリット状開口に棒板状の固定手段を嵌合することによって、火力調節レバーの位置を固定して、バーナの火力を固定する。このように簡単な構成によって、火力調節レバーの調節位置固定が可能となるので、安価に実施できる。
しかも、スリット状開口を塞いでいるため、スリット状開口からごみやほこりが器具内に入り込むことも防止できるし、開口部がなくなることにより、器具の外観がすっきりとまとまりデザイン性も向上する。 Moreover, the rice cooker of Claim 2 of this invention fixes the position of a thermal-power adjustment lever by fitting a stick-plate-shaped fixing means to the slit-shaped opening to which a thermal power adjustment lever moves, and the thermal power of a burner is fixed. Fix it. Since the adjustment position of the heating power adjusting lever can be fixed by such a simple configuration, the heating power adjusting lever can be implemented at low cost.
In addition, since the slit-shaped opening is closed, dust and dust can be prevented from entering the instrument from the slit-shaped opening, and the appearance of the instrument is neatly organized and the design is improved by eliminating the opening.

一旦決めた火力調節位置で常に同一火力で同一品質の炊飯を可能にするという目的を、大きなコストアップすることなく実現した。 The goal of enabling cooked rice of the same quality with the same thermal power at the thermal power adjustment position once decided was realized without increasing the cost.

以上説明した本発明の構成・作用を一層明らかにするために、以下本発明の炊飯器の好適な実施例について説明する。
本発明の実施例１としての炊飯器１は、図１に示すように、米、水を収納する釜２と、釜２を燃焼加熱するバーナ３と、バーナ３へ燃料ガスを供給するガス供給部４と、点火・消火・火力調節を操作する操作部５とからなる。このバーナ３には、点火操作と連動して燃料ガスへ着火する点火器６と、燃料ガスを放出して点火を補助する点火パイロットバーナ７とが設けられるとともに、燃焼熱によって熱起電力を発生する熱電対９が設けられる。 In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the rice cooker of the present invention will be described below.
As shown in FIG. 1, a rice cooker 1 as Example 1 of the present invention includes a pot 2 for storing rice and water, a burner 3 for burning and heating the pot 2, and a gas supply for supplying fuel gas to the burner 3. The unit 4 and an operation unit 5 for operating ignition / extinguishing / heating power adjustment. The burner 3 is provided with an igniter 6 that ignites the fuel gas in conjunction with the ignition operation, and an ignition pilot burner 7 that discharges the fuel gas to assist the ignition, and generates a thermoelectromotive force by the combustion heat. A thermocouple 9 is provided.

ガス供給部４には、上流より、点火レバー１０による点火操作により押動されてガス流路を開き、燃焼時に熱電対９による熱起電力によって開弁状態に保持されるマグネット式安全弁１１と、同じく、点火操作によりガス流路を開閉するメイン弁１２と、後述する火力調節レバー１３による上下のスライド操作によりバーナ３への燃料ガス流量を調節するニードル弁１４とが設けられ、その下流でバーナ３に連通されている。
また、マグネット式安全弁１１とメイン弁１２間の流路から一つの流路が分岐され、この流路は点火パイロットバーナ７へ連通している。また、この分岐路には、流路を開閉する点火パイロット弁１５が設けられる。 From the upstream, the gas supply unit 4 is pushed by an ignition operation by an ignition lever 10 to open a gas flow path, and a magnet-type safety valve 11 that is kept open by a thermoelectromotive force by a thermocouple 9 during combustion, Similarly, there are provided a main valve 12 that opens and closes a gas flow path by an ignition operation, and a needle valve 14 that adjusts the flow rate of fuel gas to the burner 3 by an up and down sliding operation by a heating power adjusting lever 13 to be described later. 3 is communicated.
One flow path is branched from the flow path between the magnet type safety valve 11 and the main valve 12, and this flow path communicates with the ignition pilot burner 7. In addition, an ignition pilot valve 15 that opens and closes the flow path is provided in this branch path.

操作部５には、点火操作が行われる点火レバー１０と、火力調節が行われる火力調節レバー１３とが設けられる。点火レバー１０は、点火操作によってマグネット式安全弁１１、メイン弁１２、点火パイロット弁１５を開弁し、センサ部１８の感温メタル２７を釜底に当接し、点火器６を作動するように設けられる。
また、火力調節レバー１３は、調節操作によってニードル弁１４の開度を変えてバーナ３への火力を調節するように設けられる（図２に炊飯器の外観図、図３に火力調節レバー部の拡大図を示す）。尚、点火レバー１０は、点火操作によって停止位置から終端位置まで押動され、手を離すと点火パイロット弁１５を閉弁し、マグネット式安全弁１１の閉弁を自由とする位置まで戻って係止され、メイン弁１２の開弁を保つ関係に設けられる。 The operation unit 5 is provided with an ignition lever 10 that performs an ignition operation and a thermal power adjustment lever 13 that performs thermal power adjustment. The ignition lever 10 is provided to open the magnet type safety valve 11, the main valve 12, and the ignition pilot valve 15 by an ignition operation, abut the temperature sensitive metal 27 of the sensor unit 18 on the bottom of the hook, and operate the igniter 6. It is done.
Further, the heating power adjusting lever 13 is provided so as to adjust the heating power to the burner 3 by changing the opening of the needle valve 14 by adjusting operation (FIG. 2 is an external view of the rice cooker, and FIG. Enlarged view is shown). The ignition lever 10 is pushed from the stop position to the end position by the ignition operation. When the ignition lever 10 is released, the ignition pilot valve 15 is closed, and the magnet safety valve 11 is returned to a position where the valve is free to be locked. The main valve 12 is kept open.

ここで、火力調節レバー１３について、図３、図４、図５を用いて説明する。尚、図４は、図３中の一点鎖線Ａ−Ａでの断面図であり、図５は、図３中の一点鎖線Ｂ−Ｂでの断面図である。
火力調節レバー１３は、器体パネル前面下部に、垂直方向に開口されたスリット孔１９を挿通して設けられる。火力調節レバー１３の先端には、つまみ２０が取り付けられる。スリット孔１９の周りには、火力調節レバー１３の調節位置に対する最適な炊飯量が表示される（２０合、１６合、１２合、８合）。
そして、火力調節レバー１３をスリット孔１９内を手で上下にスライドさせることにより、炊飯量に応じた所望の火力となるようにニードル弁１４の開度が変えられる。 Here, the heating power adjusting lever 13 will be described with reference to FIGS. 3, 4, and 5. 4 is a cross-sectional view taken along one-dot chain line AA in FIG. 3, and FIG. 5 is a cross-sectional view taken along one-dot chain line BB in FIG.
The thermal power adjusting lever 13 is provided in the lower part of the front surface of the body panel by inserting a slit hole 19 opened in the vertical direction. A knob 20 is attached to the tip of the thermal power adjustment lever 13. Around the slit hole 19, the optimal amount of rice cooking with respect to the adjustment position of the heating power adjustment lever 13 is displayed (20 go, 16 go, 12 go, 8 go).
And the opening degree of the needle valve 14 is changed so that it may become the desired heating power according to the amount of rice cooking by sliding the heating power control lever 13 up and down by the inside of the slit hole 19 by hand.

また、本実施例の炊飯器１には、図６に示すように、火力調節レバー１３の調節位置を固定するための、器具本体とは別部材からなる固定部材２１が備えられる。この固定部材２１は、スリット孔１９に嵌合可能な棒板状に成型された樹脂部材であり、上部と下部がそれぞれ中間部２２よりも幅広に形成され、上段部２３と下段部２４とが全周にわたって形成される。中間部２２及び下段部２４は、中空に形成され、断面が略コの字状となる。このため、中間部２２や下段部２４を横から押すと樹脂が弾性変形して内側に狭まり、押すのを止めると復元力によって元の形に戻る。
また、中間部２２の幅は、スリット孔１９の幅とほぼ同じ幅に形成される（ここでいう幅とは、火力調節レバー１３のスライド方向に対して直交する方向をいう）。中間部２２の長手方向の長さもスリット孔１９の長さとほぼ同じ長さに形成される。 Moreover, as shown in FIG. 6, the rice cooker 1 of a present Example is equipped with the fixing member 21 which consists of a member different from the instrument main body for fixing the adjustment position of the thermal-power adjustment lever 13. As shown in FIG. The fixing member 21 is a resin member molded into a bar plate shape that can be fitted into the slit hole 19, and the upper and lower portions are formed wider than the intermediate portion 22, and the upper step portion 23 and the lower step portion 24 are formed. It is formed over the entire circumference. The intermediate portion 22 and the lower step portion 24 are formed in a hollow shape and have a substantially U-shaped cross section. For this reason, when the intermediate portion 22 and the lower step portion 24 are pushed from the side, the resin is elastically deformed and narrows inward, and when the pushing is stopped, the original shape is restored by the restoring force.
Further, the width of the intermediate portion 22 is formed to be substantially the same as the width of the slit hole 19 (the width here means a direction orthogonal to the sliding direction of the heating power adjusting lever 13). The length in the longitudinal direction of the intermediate portion 22 is also formed to be approximately the same as the length of the slit hole 19.

固定部材２１の表面には、複数の炊飯量目盛り線２５（２０合、１６合、１２合、８合）が設けられ、各炊飯量目盛り線２５の位置には、分断用のスリット２６がその両側を残して設けられ、各炊飯量目盛り位置で二つの部材に分断できるようになっている（図７）。また、炊飯量目盛り線２５もスリット状に開口されている。このスリット状の開口の幅は、火力調節レバーの板厚とほぼ同じ幅に形成される。
そして、この分断した二つの固定部材２１を火力調節レバー１３を中心として火力調節レバー１３の両側を挟み込むようにして、スリット孔１９に嵌め込むことによって、火力調節レバー１３の調節位置が固定できる。 A plurality of rice cooking scale lines 25 (20 go, 16 go, 12 go, 8 go) are provided on the surface of the fixing member 21, and a slit 26 for dividing is provided at each rice cooking scale graduation line 25. It is provided leaving both sides, and can be divided into two members at each cooked rice scale position (FIG. 7). Moreover, the rice cooking amount scale line 25 is also opened in a slit shape. The width of the slit-like opening is formed to be approximately the same as the thickness of the heating power adjusting lever.
The adjustment position of the thermal power adjusting lever 13 can be fixed by fitting the divided two fixing members 21 into the slit holes 19 so as to sandwich both sides of the thermal power adjusting lever 13 with the thermal power adjusting lever 13 as the center.

次に、点火・消火時の各部の動作を図１に基づいて説明する。
停止状態では、センサ部１８は釜底面から離脱しているためにメイン弁１２を閉弁している。この状態で、点火レバー１０に押圧操作がされると、マグネット式安全弁１１、メイン弁１２、点火パイロット弁１５が順次開弁し、センサ部１８を釜底に押しつけて吸着させるとともに、点火器６を作動する。そして、この一連の動作により、燃料ガスがバーナ３、点火パイロットバーナ７に供給されて点火する。また、マグネット式安全弁１１には燃焼炎に臨む熱電対９からの発生電流が流れ、この熱起電力によってマグネット式安全弁１１が開弁保持される。更に、センサ部１８は感温メタル２７の吸着力が戻しバネ２８の力に打ち勝って釜底に吸着し、釜底との当接状態が保持される。
この押圧操作の後、手を離すと、点火レバー１０が、メイン弁１２を開弁したまま、点火パイロット弁１５を閉じるとともに、マグネット式安全弁１１の閉弁を自由とする位置まで戻って係止され、燃焼が継続される。 Next, the operation of each part during ignition / extinguishing will be described with reference to FIG.
In the stop state, the sensor unit 18 is detached from the bottom surface of the hook, and therefore the main valve 12 is closed. In this state, when the ignition lever 10 is pressed, the magnet safety valve 11, the main valve 12, and the ignition pilot valve 15 are sequentially opened, and the sensor unit 18 is pressed against the bottom of the hook to be adsorbed, and the igniter 6 Actuate. By this series of operations, the fuel gas is supplied to the burner 3 and the ignition pilot burner 7 to ignite. Further, a current generated from the thermocouple 9 facing the combustion flame flows through the magnet safety valve 11, and the magnet safety valve 11 is held open by this thermoelectromotive force. Further, in the sensor unit 18, the adsorption force of the temperature-sensitive metal 27 overcomes the force of the return spring 28 and adsorbs to the bottom of the hook, and the contact state with the bottom of the hook is maintained.
When the hand is released after this pressing operation, the ignition lever 10 closes the ignition pilot valve 15 with the main valve 12 open, and returns to the position where the magnet-type safety valve 11 can be freely closed and locked. And combustion continues.

また、消火に際しては、点火レバー１０を持ち上げることによって点火レバー１０が停止位置まで戻り、メイン弁１２が閉じて消火をする。 Further, when extinguishing the fire, the ignition lever 10 is returned to the stop position by lifting the ignition lever 10, and the main valve 12 is closed to extinguish the fire.

また、炊飯時には、火力調節レバー１３でバーナ３の火力を調節することにより、ニードル弁１４の開度が調節され各炊飯量に応じた最適な火力でおいしくご飯を炊くことができる。例えば、１６合のお米を炊く場合には、火力調節レバー１３を１６合と表示されている火力調節位置にセットする。
そして、このように好みの火力に火力調節レバー１３をセットした後に、図８に示すように、固定部材２１を二つの部材に破断し（この場合には、１６合の炊飯量目盛り線２５の位置のスリット２６で破断）、それぞれの固定部材２１を火力調節レバー１３をスライド方向の両側から挟み込むようにしてスリット孔１９に嵌め込むことによって、火力調節レバー１３の火力調節位置をメカ的に固定することができる。
この際、固定部材２１の下段部２４からスリット孔１９内に押し込んでいくと、固定部材２１が中空なため、下段部２４及び中間部２２が樹脂の弾性変形により内側に狭まってスリット孔１９内に固定部材２１が入り込んでいく。さらに押し込んでいき下段部２４がスリット孔１９に完全に押し込まれると、カチッと音がして中間部２２がスリット孔１９にはまり込んで（図９、図１０参照）、スリット孔１９の隙間を塞いで火力調節レバー１３の動きを禁止するのである。この際、下段部２４がスリット孔１９の幅よりもひろいため、抜け止めとなる。 Moreover, at the time of rice cooking, the opening degree of the needle valve 14 is adjusted by adjusting the heating power of the burner 3 with the heating power adjusting lever 13, and the rice can be cooked deliciously with the optimum heating power according to the amount of rice cooking. For example, when cooking 16 rice, the thermal power adjustment lever 13 is set to the thermal power adjustment position displayed as 16 go.
Then, after setting the heating power adjustment lever 13 to the desired heating power in this way, as shown in FIG. 8, the fixing member 21 is broken into two members (in this case, the 16-cooked rice cooking scale 25 The position of the heating power adjustment lever 13 is mechanically fixed by fitting each fixing member 21 into the slit hole 19 so that the heating power adjustment lever 13 is sandwiched from both sides in the sliding direction. can do.
At this time, when the fixing member 21 is pushed into the slit hole 19 from the lower step portion 24, the fixing member 21 is hollow, so that the lower step portion 24 and the intermediate portion 22 are narrowed inward due to elastic deformation of the resin, and the inside of the slit hole 19. The fixing member 21 enters into. When the lower step portion 24 is further pushed into the slit hole 19 further, a click is made and the intermediate portion 22 fits into the slit hole 19 (see FIGS. 9 and 10), and the gap between the slit holes 19 is reduced. The movement of the heating power adjustment lever 13 is prohibited by closing. At this time, since the lower step portion 24 is wider than the width of the slit hole 19, it is prevented from coming off.

以上説明したように、本実施例の炊飯器１によれば、一旦好みの火力にセットした後に、スリット孔１９に固定部材２１を嵌め込むと、火力調節レバー１３の火力調節位置を固定することができ、常に同一火力で同一品質の炊飯が可能となる。しかも、スリット孔１９に固定部材２１を嵌め込むといった簡単な構成で火力を固定できるため、大きなコストアップをすることなく安価に実施できる。
さらに、スリット孔１９を塞いでいるため、スリット孔１９からごみやほこりが器具内に入り込むことも防止できるし、開口部がなくなることにより、器具の外観がすっきりとまとまりデザイン性も向上する。
また、炊飯量目盛り線２５のスリット状開口の幅と火力調節レバー１３の板厚とを同一寸法としておくことで、火力調節レバー１３の上下両側も固定部材２１で覆うことができ、一層見栄えが良くなる。さらに、このスリット状開口の長さと火力調節レバー１３の幅を同一寸法にすれば、火力調節レバー１３の周囲を完全に覆うことができる。 As explained above, according to the rice cooker 1 of the present embodiment, after setting the thermal power once to the desired thermal power, when the fixing member 21 is fitted into the slit hole 19, the thermal power adjustment position of the thermal power adjustment lever 13 is fixed. It is possible to cook rice of the same quality with the same heating power. In addition, since the heating power can be fixed with a simple configuration in which the fixing member 21 is fitted into the slit hole 19, it can be carried out inexpensively without increasing the cost.
Furthermore, since the slit hole 19 is closed, dust and dust can be prevented from entering the instrument from the slit hole 19, and the appearance of the instrument is neatly organized and the design is improved by eliminating the opening.
In addition, by setting the width of the slit-shaped opening of the rice cooking scale 25 and the thickness of the heating power adjustment lever 13 to be the same size, both the upper and lower sides of the heating power adjustment lever 13 can be covered with the fixing member 21, so Get better. Furthermore, if the length of the slit-shaped opening and the width of the thermal power adjusting lever 13 are the same, the periphery of the thermal power adjusting lever 13 can be completely covered.

以上本発明の実施例について説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。 Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various modes without departing from the gist of the present invention.
