Description

本発明は、ガス炊飯器に関する。 The present invention relates to a gas rice cooker.

従来、ガスの燃焼熱により炊飯を行うガス炊飯器が知られている（例えば、特許文献１参照）。例えば、商用電源を用いないガス炊飯器では、点火スイッチが操作されると、ガス通路が開き、ガスバーナの炎孔部からガスが噴出され、このガスが操作によって生じる火花により点火され、バーナの燃焼が開始され、米と水が収容された内釜が熱せられる。この火花は、例えば、圧電点火装置によって生じさせることができる。圧電点火装置は、点火スイッチの操作によって圧電素子から生じる起電力に基づき、火花を発生させる。温度を検出する感熱ヘッドが内釜の底面に接触しており、内釜の温度が所定温度に達すると、ガス通路が閉じて燃焼が停止され、炊飯が完了する。 2. Description of the Related Art Conventionally, a gas rice cooker that cooks rice by combustion heat of gas is known (see Patent Document 1, for example). For example, in a gas rice cooker that does not use a commercial power source, when an ignition switch is operated, the gas passage opens and gas is ejected from the flame port of the gas burner, and this gas is ignited by sparks generated by the operation, causing the burner to burn. is started and the inner pot containing rice and water is heated. This spark can be generated, for example, by a piezoelectric igniter. A piezoelectric ignition device generates a spark based on an electromotive force generated from a piezoelectric element by operating an ignition switch. A thermal head that detects the temperature is in contact with the bottom surface of the inner pot, and when the temperature of the inner pot reaches a predetermined temperature, the gas passage is closed, combustion is stopped, and rice cooking is completed.

上部筐体４には内周面の上部から内方に張り出した、内釜支持部４５が設けられる（図３参照）。内釜支持部４５は平面視略リング状である。内釜支持部４５の内縁部の内径が、内釜８のフランジ部８１の外径よりも小さく、且つ内釜８の胴部８０の外径よりも大きい。従って、内釜８は、内釜支持部４５にて吊り下げられて支持され、且つ蓋部５を開いた状態で、上部筐体４の内側に着脱自在に設けられる。 The upper housing 4 is provided with an inner hook support portion 45 projecting inward from the upper portion of the inner peripheral surface (see FIG. 3). The inner hook support portion 45 is substantially ring-shaped in a plan view. The inner diameter of the inner edge portion of the inner hook support portion 45 is smaller than the outer diameter of the flange portion 81 of the inner hook 8 and larger than the outer diameter of the body portion 80 of the inner hook 8 . Therefore, the inner hook 8 is suspended and supported by the inner hook supporting portion 45, and is detachably provided inside the upper housing 4 with the lid portion 5 opened.

ここで、ガス炊飯器１の炊飯時の動作を簡単に説明する。使用者により下部筐体３の点火スイッチ３１が押し下げられると、ガス量調節装置７７に設けられたガス弁が開弁する。バーナ７２にガスが供給される。イグナイタ７４は、点火スイッチ３１の押し下げられることにより動作し、イグナイタ７４の点火部７４１から火花を生じる。該火花によって、バーナ７２の炎孔部７２１から噴出するガスが点火される。温度センサ７５の熱感知部７５１がガスの燃焼熱を検出する。温度センサ７５の熱により生じた電力により該ガス弁が開弁状態で維持され、バーナ７２は燃焼状態が維持される。内釜８が熱せられ、炊飯が開始する。内釜８の底部が所定の温度に達すると、感熱ヘッド７３が該所定の温度を検出し、該ガス弁が閉弁される。バーナ７２へガスが供給されなくなり、バーナ７２の燃焼が停止し、炊飯が完了する。 Here, the operation of the gas rice cooker 1 when cooking rice will be briefly described. When the user pushes down the ignition switch 31 of the lower housing 3, the gas valve provided in the gas amount control device 77 is opened. Gas is supplied to the burner 72 . The igniter 74 operates when the ignition switch 31 is pushed down, and sparks are generated from the ignition portion 741 of the igniter 74 . The spark ignites the gas ejected from the flame hole portion 721 of the burner 72 . A heat sensing portion 751 of the temperature sensor 75 detects the combustion heat of the gas. Electric power generated by the heat of the temperature sensor 75 keeps the gas valve open and the burner 72 kept burning. The inner pot 8 is heated and rice cooking starts. When the bottom of the inner pot 8 reaches a predetermined temperature, the thermal head 73 detects the predetermined temperature and the gas valve is closed. Gas is no longer supplied to the burner 72, combustion of the burner 72 is stopped, and rice cooking is completed.

Further, the length of the case rib 108 in the left-right direction is the same as the length of the upper surface of the fixing portion 101 in the left-right direction. An upper end portion of the case rib 108 is formed substantially horizontally. With the battery case 10 fixed to the upper wall portion 711 of the support member 71 , the pair of case ribs 108 are brought into tight contact with the lower surface of the upper wall portion 711 . Therefore, the battery case 10 can be fixed to the lower surface of the upper wall portion 711 without rattling.

電池ケース１０の支持部材７１への取り付け方法の一例を説明する。作業者は、電池ケース１０の装着口１０２を下向きにした状態で、支持部材７１の上壁部７１１の下側に配置する。そして、上壁部７１１の仮固定スリット７１４に対し、電池ケース１０の鉤部１０４を位置決めし、上壁部７１１の上壁部孔７１５に対し、電池ケース１０のケース固定筒部１０５の上端部を位置決めする。次いで、仮固定スリット７１４に対して鉤部１０４を下方から挿入して、上壁部７１１に鉤部１０４の係止部１０４Ａを係合させて仮固定する。ケース固定筒部１０５の上端部及び一対のケースリブ１０８を上壁部７１１に密着して当接する。さらに、上壁部孔７１５を介してケース固定筒部１０５のケース固定孔１０５Ａに螺子７１６にて締結する。電池ケース１０は、支持部材７１に固定される。 An example of a method of attaching the battery case 10 to the support member 71 will be described. The operator places the battery case 10 below the upper wall portion 711 of the support member 71 with the mounting opening 102 facing downward. Then, the hook portion 104 of the battery case 10 is positioned with respect to the temporary fixing slit 714 of the upper wall portion 711 , and the upper end portion of the case fixing cylindrical portion 105 of the battery case 10 is positioned with respect to the upper wall portion hole 715 of the upper wall portion 711 . position. Next, the hook portion 104 is inserted into the temporary fixing slit 714 from below, and the engaging portion 104A of the hook portion 104 is engaged with the upper wall portion 711 for temporary fixing. The upper end portion of the case fixing tubular portion 105 and the pair of case ribs 108 are in close contact with the upper wall portion 711 . Further, the screw 716 is fastened to the case fixing hole 105A of the case fixing tubular portion 105 through the upper wall portion hole 715 . Battery case 10 is fixed to support member 71 .

図８、図９を参照し、ガード部材１１の構造を説明する。なお、本実施形態では、説明の便宜上、下部筐体３に固定されたガード部材１１の向きで説明する。ガード部材１１は、プラスチック製である。ガード部材１１は、耐水性、耐熱性を有することが望ましい。ガード部材１１は、下部筐体３に固定された状態で、内側に電池ケース１０を配置する（図４、図１０参照）。 The structure of the guard member 11 will be described with reference to FIGS. 8 and 9. FIG. In this embodiment, for convenience of explanation, the direction of the guard member 11 fixed to the lower housing 3 will be explained. The guard member 11 is made of plastic. The guard member 11 preferably has water resistance and heat resistance. The guard member 11 has the battery case 10 arranged inside thereof while being fixed to the lower housing 3 (see FIGS. 4 and 10).

ガード部材１１は、筒状部１１０、張出部１１１、突出部１１２、ガード固定孔１１３、及びテーパ部１１４を有する。筒状部１１０は、略角筒状で、外周の大きさが下部筐体３の開口部３４の大きさより若干小さい程度で、ほぼ等しい大きさである。また、筒状部１１０の内周の大きさは、電池ケース１０の収容部１００の前後左右方向の大きさより若干大きい程度で、ほぼ等しい大きさである。従って、筒状部１１０の板厚は、下部筐体３の開口部３４と収容部１００の外周面との隙間の幅より若干短い程度で、ほぼ等しい長さである。筒状部１１０の高さは、収容部１００の高さと略同一である。 The guard member 11 has a tubular portion 110 , an overhanging portion 111 , a projecting portion 112 , a guard fixing hole 113 and a tapered portion 114 . The cylindrical portion 110 has a substantially square cylindrical shape, and the size of the outer periphery is slightly smaller than the size of the opening 34 of the lower housing 3, but substantially the same size. In addition, the size of the inner periphery of the tubular portion 110 is slightly larger than the size of the storage portion 100 of the battery case 10 in the front, rear, left, and right directions, and is substantially the same size. Therefore, the plate thickness of the cylindrical portion 110 is slightly shorter than the width of the gap between the opening 34 of the lower housing 3 and the outer peripheral surface of the housing portion 100, and has a length that is substantially equal. The height of the tubular portion 110 is substantially the same as the height of the housing portion 100 .

張出部１１１は、筒状部１１０の下端部から外方に張り出して設けられ、平面視略矩形状である。張出部１１１の左側の外周部は緩やかに湾曲する円弧状に形成される。張出部１１１の上面は、略水平である。張出部１１１の大きさは、ガード部材１１が下部筐体３の底部に固定された状態で、下部筐体３の底部から側方に張り出さず、脚部３３及び空気孔３５等に干渉しない。張出部１１１の左側の外周部は緩やかに湾曲しており、下部筐体３の底部から張り出さない。筒状部１１０の内壁面の下端部と張出部１１１との接続部には、筒状部１１０側から張出部１１１側に向かって拡がるように外側に傾斜するテーパ部１１４が設けられる。 The protruding portion 111 protrudes outward from the lower end portion of the cylindrical portion 110 and has a substantially rectangular shape in plan view. The outer peripheral portion on the left side of the projecting portion 111 is formed in a gently curving arc shape. The upper surface of the projecting portion 111 is substantially horizontal. The size of the projecting portion 111 is such that when the guard member 11 is fixed to the bottom of the lower housing 3 , it does not project sideways from the bottom of the lower housing 3 and does not interfere with the legs 33 and the air holes 35 . do not do. The outer peripheral portion on the left side of the protruding portion 111 is gently curved and does not protrude from the bottom portion of the lower housing 3 . A tapered portion 114 is provided at the connecting portion between the lower end portion of the inner wall surface of the tubular portion 110 and the overhanging portion 111 so as to extend outward from the tubular portion 110 toward the overhanging portion 111 .

突出部１１２は、張出部１１１の下面における左側の外周部に設けられ、下方に突出している。突出部１１２の下方に突出する長さは、脚部３３より短い。ガード部材１１が下部筐体３の底部に固定された状態では、突出部１１２は、下部筐体３底部の外周部側に位置する。 The protruding portion 112 is provided on the left outer peripheral portion of the lower surface of the overhanging portion 111 and protrudes downward. The downward protruding length of the projecting portion 112 is shorter than that of the leg portion 33 . When the guard member 11 is fixed to the bottom of the lower housing 3 , the protrusion 112 is positioned on the outer peripheral side of the bottom of the lower housing 3 .

ガード固定孔１１３は、張出部１１１の右前方角部に設けられる。なお、下部筐体３の底部には、ガード固定孔１１３に対応する位置に筐体側孔（図示略）が設けられる。ガード固定孔１１３は、ガード部材１１が下部筐体３に固定された状態で、下部筐体３底部の中央側に位置する。従って、ガード固定孔１１３は、下部筐体３の底部を伝ってきた吹き零れ等の水が接触し難い位置にある。よって、ガード固定孔１１３を介してガード部材１１を下部筐体３に対して固定する螺子３７（図２参照）が腐食することを防止できる。 The guard fixing hole 113 is provided at the right front corner of the projecting portion 111 . A housing-side hole (not shown) is provided in the bottom of the lower housing 3 at a position corresponding to the guard fixing hole 113 . The guard fixing hole 113 is located on the central side of the bottom of the lower housing 3 when the guard member 11 is fixed to the lower housing 3 . Therefore, the guard fixing hole 113 is located at a position where it is difficult for water, such as blowing over, to come in contact with the bottom of the lower housing 3 . Therefore, the screws 37 (see FIG. 2) that fix the guard member 11 to the lower housing 3 via the guard fixing holes 113 can be prevented from corroding.

ガード部材１１の下部筐体３の底部への取り付け方法を説明する。作業者は、下部筐体３の底部を上方に向けた状態で、ガード部材１１の筒状部１１０の上端部が下向きにした状態で該底部の上側に配置する。そして、該底部に設けられた開口部３４に対し、ガード部材１１の筒状部１１０を上方から位置決めする。上記の通り、筒状部１１０の板厚は、下部筐体３の開口部３４と収容部１００の外周面との隙間の幅より若干短い程度で、ほぼ等しい長さである。よって、筒状部１１０は、開口部３４の内縁部と収容部１００の外周面との隙間を遊挿可能である。 A method of attaching the guard member 11 to the bottom of the lower housing 3 will be described. With the bottom portion of the lower housing 3 facing upward, the operator places the cylindrical portion 110 of the guard member 11 above the bottom portion with the upper end portion facing downward. Then, the cylindrical portion 110 of the guard member 11 is positioned from above with respect to the opening portion 34 provided in the bottom portion. As described above, the plate thickness of the cylindrical portion 110 is slightly shorter than the width of the gap between the opening 34 of the lower housing 3 and the outer peripheral surface of the housing portion 100, and has substantially the same length. Therefore, the tubular portion 110 can be loosely inserted into the gap between the inner edge portion of the opening portion 34 and the outer peripheral surface of the housing portion 100 .

そして、開口部３４の内縁部と収容部１００の外周面の夫々が、該隙間に対して筒状部１１０を挿入する際に、筒状部１１０のガイドとして機能させることができる。筒状部１１０を該隙間に挿入する。ここで上記の通り、張出部１１１の上面は略水平であり、下部筐体３の底部も開口部３４周辺で略水平である。従って、筒状部１１０を該隙間に挿入していくと、張出部１１１の上面が下部筐体３の底部と密着して重なる。このとき、ガード固定孔１１３は、下部筐体３に設けられた筐体側孔と重なり配置されるので、ガード固定孔１１３を介して筐体側孔に螺子３７を締結する。これにより、ガード部材１１は、下部筐体３の底部に固定される。 Each of the inner edge of the opening 34 and the outer peripheral surface of the accommodating portion 100 can function as a guide for the tubular portion 110 when the tubular portion 110 is inserted into the gap. The tubular portion 110 is inserted into the gap. Here, as described above, the upper surface of the projecting portion 111 is substantially horizontal, and the bottom portion of the lower housing 3 is also substantially horizontal around the opening 34 . Therefore, when the tubular portion 110 is inserted into the gap, the upper surface of the protruding portion 111 closely contacts and overlaps the bottom portion of the lower housing 3 . At this time, the guard fixing hole 113 is arranged to overlap the housing side hole provided in the lower housing 3 , so the screw 37 is fastened to the housing side hole through the guard fixing hole 113 . The guard member 11 is thereby fixed to the bottom of the lower housing 3 .

ガード部材１１は、下部筐体３に固定された状態で、筒状部１１０の内側に電池ケース１０を配置する。上記の通り、筒状部１１０の板厚は、下部筐体３の開口部３４と収容部１００の外周面との隙間の幅より若干短い程度で、ほぼ等しい長さである。従って、筒状部１１０は、開口部３４の内縁部と収容部１００の外周面との隙間を塞ぐ。また、筒状部１１０の高さは、収容部１００の高さと略同一であるので、筒状部１１０は、収容部１００の外周面の全体を取り囲む。よって、筒状部１１０は、収容部１００の前壁及び後壁に夫々設けた一対のケース孔１００Ｂを取り囲むことができるので、ケース孔１００Ｂにおいて外部に露出する電池当接部１０３Ａの一部を覆い隠すことができる。 The guard member 11 arranges the battery case 10 inside the tubular portion 110 while being fixed to the lower housing 3 . As described above, the plate thickness of the cylindrical portion 110 is slightly shorter than the width of the gap between the opening 34 of the lower housing 3 and the outer peripheral surface of the housing portion 100, and has substantially the same length. Therefore, the tubular portion 110 closes the gap between the inner edge portion of the opening portion 34 and the outer peripheral surface of the housing portion 100 . Moreover, since the height of the cylindrical portion 110 is substantially the same as the height of the housing portion 100 , the cylindrical portion 110 surrounds the entire outer peripheral surface of the housing portion 100 . Therefore, the cylindrical portion 110 can surround the pair of case holes 100B provided in the front wall and the rear wall of the housing portion 100, respectively, so that a portion of the battery contact portion 103A exposed to the outside in the case hole 100B can be partially covered. can be covered up.

上記構成を備えるガス炊飯器１において、下部筐体３の底部には開口部３４が設けられ、開口部３４の内側には、電池の装着口１０２を下向きにした姿勢で電池ケース１０が収容して設けられる。よって、使用者は、下部筐体３の底部に設けられた開口部３４を介して装着口１０２から電池をそのまま取り出し、又はそのまま装着できるので、電池着脱時の作業性が向上する。また、内釜８から水が吹き零れて筐体２の外周面に付着しても、開口部３４が底部にあるので、開口部３４を介して電池ケース１０の内側に水が侵入し、電池と接触するリスクを軽減できる。従って、漏電や電池の劣化を防ぐことができる。 In the gas rice cooker 1 having the above configuration, an opening 34 is provided at the bottom of the lower housing 3, and the battery case 10 is accommodated inside the opening 34 with the battery mounting opening 102 facing downward. provided. Therefore, the user can take out the battery directly from the mounting opening 102 through the opening 34 provided at the bottom of the lower housing 3 or mount the battery as it is. Also, even if water blows out of the inner pot 8 and adheres to the outer peripheral surface of the housing 2, since the opening 34 is located at the bottom, the water enters the inside of the battery case 10 through the opening 34, causing the battery to run out of water. reduce the risk of coming into contact with Therefore, electric leakage and deterioration of the battery can be prevented.

また、電池ケース１０を下部筐体３の底部に設けたことで、開口部３４を介して露出する電池ケース１０を目立たなくできるので、ガス炊飯器１の美観を向上できる。なお、電池ケース１０の収容方法として、下部筐体３の内側に電池ケース１０を設けてスライドして取り出す方式もあるが、本実施形態においては、下部筐体３の底部に設けた開口部３４から電池を直接取り出すことができるので、スライド機構を必要としない。その分だけ省スペース化が可能であるので、下部筐体３を小型化できる。 In addition, by providing the battery case 10 at the bottom of the lower housing 3, the battery case 10 exposed through the opening 34 can be made inconspicuous, so that the appearance of the gas rice cooker 1 can be improved. As a method for accommodating the battery case 10, there is a method in which the battery case 10 is provided inside the lower housing 3 and is slid out. Since the battery can be taken out directly from the battery, there is no need for a slide mechanism. Since space can be saved by that amount, the lower housing 3 can be made smaller.

さらに、下部筐体３の底部の開口部３４には、ガード部材１１が固定される。ガード部材１１は、開口部３４の内側において電池ケース１０の収容部１００の外周面を取り囲む筒状部１１０を有する。即ち、電池当接部１０３Ａの一部が収容部１００のケース孔１００Ｂを介して露出しているが、筒状部１１０は露出部分を覆う。仮に内釜８から吹き零れた水が、筐体２の側面を伝って下方に流れ、下部筐体３の底部側に流れた場合でも、筒状部１１０が水を遮る。よって、電池ケース１０内の電池及び該露出部分に水が接触するのをさらに防止できる。 Furthermore, the guard member 11 is fixed to the opening 34 at the bottom of the lower housing 3 . Guard member 11 has a tubular portion 110 surrounding the outer peripheral surface of housing portion 100 of battery case 10 inside opening portion 34 . That is, a part of the battery contact portion 103A is exposed through the case hole 100B of the housing portion 100, but the cylindrical portion 110 covers the exposed portion. Even if water blowing out of the inner pot 8 flows downward along the side surface of the housing 2 and flows to the bottom side of the lower housing 3, the cylindrical part 110 blocks the water. Therefore, it is possible to further prevent water from contacting the batteries and the exposed portions in the battery case 10 .

さらに、下部筐体３の内側には、支持部材７１が設けられる。支持部材７１は、下部筐体３の開口部３４の内側において、電池ケース１０の装着口１０２が開口部３４に対向した状態で、電池ケース１０を支持する。ガード部材１１の筒状部１１０は、開口部３４の内縁部と電池ケース１０における収容部１００の外周面の隙間に挿入され、支持部材７１に支持された収容部１００を内側に配置する。従って、開口部３４の内縁部と収容部１００の外周面との隙間を筒状部１１０で埋めることができる。これにより、筐体２の側面及び下部筐体３の底部を伝って流れた吹き零れた水等が、開口部３４の内縁部と収容部１００の外周面との隙間を介して、電池ケース１０に到達してしまうのを防止できる。従って、電池ケース１０内の電池及び収容部１００より露出した導電性部材である電池当接部１０３Ａに水が接触するのをさらに防止できる。 Furthermore, a support member 71 is provided inside the lower housing 3 . The support member 71 supports the battery case 10 inside the opening 34 of the lower housing 3 with the mounting opening 102 of the battery case 10 facing the opening 34 . The tubular portion 110 of the guard member 11 is inserted into the gap between the inner edge of the opening 34 and the outer peripheral surface of the housing portion 100 in the battery case 10, and arranges the housing portion 100 supported by the support member 71 inside. Therefore, the gap between the inner edge portion of the opening 34 and the outer peripheral surface of the housing portion 100 can be filled with the cylindrical portion 110 . As a result, the water or the like that has flowed down along the side surface of the housing 2 and the bottom of the lower housing 3 can flow through the gap between the inner edge of the opening 34 and the outer peripheral surface of the housing 100 and into the battery case 10. can be prevented from reaching Therefore, it is possible to further prevent water from coming into contact with the battery in the battery case 10 and the battery contact portion 103A, which is a conductive member exposed from the housing portion 100 .

さらに、電池ケース１０は、支持部材７１によって開口部３４の内側において支持されるので、開口部３４の内側における位置が固定される。よって、開口部３４の内縁部と収容部１００の外周面との隙間を確保できる。そして、ガード部材１１を下部筐体３に固定する際、開口部３４の内縁部と収容部１００の外周面の夫々が、筒状部１１０を挿入するガイドとして機能する。これにより、開口部３４の内縁部と収容部１００の外周面との隙間に筒状部１１０を挿入するだけで、筒状部１１０の内側に収容部１００が配置されるので、ガード部材１１を下部筐体３の底部に対して容易に位置決めして固定できる。 Furthermore, since the battery case 10 is supported inside the opening 34 by the support member 71 , the position inside the opening 34 is fixed. Therefore, a gap between the inner edge portion of the opening 34 and the outer peripheral surface of the housing portion 100 can be secured. When the guard member 11 is fixed to the lower housing 3 , the inner edge of the opening 34 and the outer peripheral surface of the accommodating portion 100 function as guides for inserting the cylindrical portion 110 . Accordingly, simply by inserting the tubular portion 110 into the gap between the inner edge portion of the opening 34 and the outer peripheral surface of the accommodating portion 100, the accommodating portion 100 is arranged inside the tubular portion 110, so that the guard member 11 can be removed. It can be easily positioned and fixed to the bottom of the lower housing 3 .

さらに、本実施形態では、筒状部１１０の下端部より張出部１１１が外方に張り出し、且つ下部筐体３の底部に対して下方から重なって設けられる。張出部１１１は、下部筐体３の底面と重なっているので、下部筐体３の底部を伝ってきた吹き零れた水等が開口部３４を介して下部筐体３の内側に侵入を防止できる。従って、電池ケース１０内の電池及び収容部１００より露出した導電性部材である電池当接部１０３Ａに水が接触することをさらに防止できる。 Furthermore, in the present embodiment, the protruding portion 111 protrudes outward from the lower end portion of the cylindrical portion 110 and overlaps the bottom portion of the lower housing 3 from below. Since the protruding portion 111 overlaps the bottom surface of the lower housing 3, it prevents water, etc. that has flowed down the bottom of the lower housing 3 from entering the inside of the lower housing 3 through the opening 34. can. Therefore, it is possible to further prevent water from coming into contact with the battery in the battery case 10 and the battery contact portion 103A, which is a conductive member exposed from the housing portion 100 .

さらに、突出部１１２が、張出部１１１の外周部の一部に、下方に突出して設けられる。突出部１１２は、下部筐体３の外周面を伝ってきた吹き零れた水等がまず張出部１１１と接触する位置に設けられる。突出部１１２は、開口部３４を介して下部筐体３の内側に水が侵入するのを遮り、水を下方に滴下させ易くする。また、水を多く使用する炊事場であって、下部筐体３の底部に水が飛散してきた場合でも、突出部１１２が壁となる。従って、電池ケース１０内の電池及び収容部１００より露出した導電性部材である電池当接部１０３Ａに水が接触することをさらに防止できる。 Further, a protruding portion 112 is provided on a part of the outer peripheral portion of the overhanging portion 111 so as to protrude downward. The projecting portion 112 is provided at a position where the water or the like that has flowed over the outer peripheral surface of the lower housing 3 first contacts the projecting portion 111 . The protruding portion 112 prevents water from entering the inside of the lower housing 3 through the opening 34 and makes it easier for the water to drip downward. Moreover, even when water splashes on the bottom of the lower housing 3 in a kitchen that uses a lot of water, the projecting portion 112 serves as a wall. Therefore, it is possible to further prevent water from coming into contact with the battery in the battery case 10 and the battery contact portion 103A, which is a conductive member exposed from the housing portion 100 .

さらに、電池ケース１０の収容部１００から突出した端子部１０３のハーネス接続部１０３Ｂの上面は、下部筐体３の内側に設けられた支持部材７１の上壁部７１１によって覆われている。従って、仮に内釜８から吹き零れた等の水が受け皿９でも受けきれず、溢れて下部筐体３の内側に流れ伝ってきても、上壁部７１１によって、導電性部材であるハーネス接続部１０３Ｂと水との接触を防止できる。また、電池ケース１０を支持する構造を、バーナ７２等の主要な部品を支持する支持部材７１と別に設けるのではなく、支持部材７１に固定して共用させることによって、部品点数を増やすことなく、下部筐体３内において電池ケース１０を支持できる。 Further, the upper surface of the harness connection portion 103B of the terminal portion 103 protruding from the housing portion 100 of the battery case 10 is covered with the upper wall portion 711 of the support member 71 provided inside the lower housing 3 . Therefore, even if water, such as water that has blown out of the inner pot 8, cannot be received by the receiving pan 9 and overflows and flows inside the lower housing 3, the upper wall 711 prevents the harness connecting portion, which is a conductive member. Contact between 103B and water can be prevented. In addition, the structure for supporting the battery case 10 is not provided separately from the support member 71 that supports main components such as the burner 72, but by fixing it to the support member 71 and sharing it, it is possible to reduce the number of components without increasing the number of parts. The battery case 10 can be supported inside the lower housing 3 .

なお、本発明は上記実施形態に限定されるものではなく、種々の変更が可能である。例えば、図１０に示すように、上記実施形態のガード部材１１の筒状部１１０は、電池ケース１０の収容部１００を取り囲むが、収容部１００のみならず、電池ケース１０の収容部１００から突出した端子部１０３のハーネス接続部１０３Ｂまでを取り囲んでよい。 The present invention is not limited to the above embodiments, and various modifications are possible. For example, as shown in FIG. 10 , the tubular portion 110 of the guard member 11 of the above embodiment surrounds the housing portion 100 of the battery case 10 , but protrudes not only from the housing portion 100 but also from the housing portion 100 of the battery case 10 . It may surround the terminal portion 103 up to the harness connection portion 103B.

図１１を参照し、ガード部材１１の変形例であるガード部材１２の構造を説明する。ガード部材１２は、筒状部１２０、張出部１２１、突出部１２２、及びガード固定孔１２３を有する。なお、張出部１２１、突出部１２２、及びガード固定孔１２３は、ガード部材１１の、張出部１１１、突出部１１２、及びガード固定孔１１３と夫々対応し、同様の構造であるため、説明は省略する。筒状部１２０は、その高さ以外の形状は全てガード部材１１の筒状部１１０と同一である。ガード部材１２を下部筐体３に取り付けた状態において、筒状部１２０は、支持部材７１の上壁部７１１と干渉せずに、電池ケース１０の収容部１００のみならず、該収容部１００から上方に突出した一対のハーネス接続部１０３Ｂまでも取り囲むことができる。これにより、ガード部材１２は、電池当接部１０３Ａのみならず、ハーネス接続部１０３Ｂに水が接触するのを防止できる。 The structure of a guard member 12, which is a modified example of the guard member 11, will be described with reference to FIG. The guard member 12 has a tubular portion 120 , an overhanging portion 121 , a projecting portion 122 and a guard fixing hole 123 . The overhanging portion 121, the projecting portion 122, and the guard fixing hole 123 correspond to the overhanging portion 111, the projecting portion 112, and the guard fixing hole 113 of the guard member 11, respectively, and have the same structure. are omitted. The tubular portion 120 has the same shape as the tubular portion 110 of the guard member 11 except for its height. In a state where the guard member 12 is attached to the lower housing 3 , the cylindrical portion 120 does not interfere with the upper wall portion 711 of the support member 71 , so that not only the storage portion 100 of the battery case 10 but also the storage portion 100 can be secured. A pair of harness connection portions 103B protruding upward can also be surrounded. Accordingly, the guard member 12 can prevent water from contacting not only the battery contact portion 103A but also the harness connection portion 103B.

ガード部材１１（１２）は、張出部１１１（１２１）を省略してもよい。この場合、筒状部１１０（１２０）の下端部が下部筐体３の開口部３４より下方に突出している。これにより、吹き零れた水等が下部筐体３の底部に伝ってきた場合に、筒状部１１０（１２０）が、電池ケース１０への水の侵入を遮り、水を下方に滴下させ易くなる。また、水を多く使用する炊事場であって、飛び散った水が下部筐体３の底部に付着した場合でも、筒状部１１０（１２０）が電池ケース１０に対する壁となる。従って、電池ケース１０内の電池及び収容部１００より露出した導電性部材である電池当接部１０３Ａに水が接触することを防止できる。 The guard member 11 (12) may omit the projecting portion 111 (121). In this case, the lower end of the tubular portion 110 (120) protrudes downward from the opening 34 of the lower housing 3 . As a result, when water or the like blows up and reaches the bottom of the lower housing 3, the tubular portion 110 (120) blocks the entry of water into the battery case 10, making it easier for the water to drip downward. . Further, even in a kitchen where a lot of water is used and splashed water adheres to the bottom of the lower housing 3 , the tubular portion 110 ( 120 ) acts as a wall against the battery case 10 . Therefore, it is possible to prevent water from coming into contact with the battery in the battery case 10 and the battery contact portion 103A, which is a conductive member exposed from the housing portion 100 .
