産業上の利用分野
本発明は、一般家庭において使用する炊飯器に
関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker for use in general households.
従来例の構成とその問題点
従来、この種の炊飯器においては、第１図に示
すように、本体１に外鍋２を固定し、この外鍋２
の外側面には透孔３を設け、この透孔３には突出
して内鍋４に当接する熱感知素子５を設けてい
た。この熱感知素子５は取付台６により支持され
て、外鍋２の下面の適当な位置にビス等により固
定されたものが一般的であつた。なお７はガラス
繊維等の断熱材である。しかし、この構成では、
熱感知素子５を取替える必要が生じたとき、本体
１をひつくり返して、ビスを取り除いた後に取付
台６をはずして熱感知素子５を交換する必要があ
るため、重い本体１を逆にひつくり返さねばなら
ない不便があつた。また、熱感知素子５は、飯を
保温するときに経験的に、内鍋４に当接する位置
は決まつており、この位置は従来の炊飯器におい
ては取付台５の長さ、すなわち、ビスで取り付け
る位置より熱感知素素５が、内鍋４に当接するま
での長さは各容量の炊飯器により変えていた。Conventional structure and its problems Conventionally, in this type of rice cooker, as shown in FIG. 1, an outer pot 2 is fixed to a main body 1,
A through hole 3 was provided on the outer surface of the container, and a heat sensing element 5 was provided in the through hole 3 to protrude and come into contact with the inner pot 4. This heat sensing element 5 was generally supported by a mounting base 6 and fixed at an appropriate position on the lower surface of the outer pot 2 with screws or the like. Note that 7 is a heat insulating material such as glass fiber. However, with this configuration,
When it becomes necessary to replace the heat sensing element 5, it is necessary to turn the main body 1 over, remove the screws, remove the mounting base 6, and replace the heat sensing element 5, so the heavy main body 1 must be turned over. I had the inconvenience of having to return it. Further, the position where the heat sensing element 5 contacts the inner pot 4 when keeping rice warm is determined empirically, and in conventional rice cookers, this position is determined by the length of the mounting base 5, that is, the screw The length from the installation position until the heat sensing element 5 contacts the inner pot 4 was varied depending on the capacity of the rice cooker.
このため、従来ある種々の容量、例えば0.6
炊、1.0炊、1.5炊、1.8炊、2.3炊、3.6
炊……5.4炊のそれぞれに対して長さを変えて
いるため多くの種類が必要であり、またその金型
製作、検査あるいは、工程での誤まつた取付台６
の組立など、様々な問題があつた。 For this reason, various conventional capacitances, e.g. 0.6
Cooking, 1.0 cooking, 1.5 cooking, 1.8 cooking, 2.3 cooking, 3.6
Cooking...5.4 Since the length is different for each type of cooking, many types are required, and in addition, mold manufacturing, inspection, or incorrect installation during the process.6.
There were various problems such as assembly.
また、保温兼用電気釜（以下、ジヤー炊飯器と
称する）においては、外鍋２の外側に断熱材７を
設けているため、取付台６により断熱材７が外鍋
２に充分密着しなく、保温に対して不利であつ
た。これは、断熱材７がガラス繊維でできてお
り、このガラス繊維に含まれる空気量により断熱
効果が良くなることは良く知られているが、取付
台６により断熱材７が薄くなり、断熱効果が悪く
なるからであつた。 In addition, in the heat-retaining electric rice cooker (hereinafter referred to as a jar rice cooker), since the heat insulating material 7 is provided on the outside of the outer pot 2, the heat insulating material 7 does not come into close contact with the outer pot 2 due to the mounting base 6. It was disadvantageous for heat retention. This is because the heat insulating material 7 is made of glass fiber, and it is well known that the amount of air contained in this glass fiber improves the heat insulating effect. This was because it would make things worse.
以上述べたように、取付台６が外鍋２の底面で
ビス等により取り付けることは、種々の問題があ
つた。 As described above, attaching the mounting base 6 to the bottom surface of the outer pot 2 with screws or the like has various problems.

するものである。Purpose of the Invention The present invention solves these conventional problems, prevents incorrect insertion during assembly of the mounting base, reduces various procedures from ordering parts to inspection, and simplifies mold production. The present invention provides a rice cooker that is easier to assemble and has better heat retention performance.

うに外側に拡ろがる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, reference numeral 8 denotes a negative characteristic thermistor that senses heat, and is insulated and protected by a heat-resistant tube 11 made of soft resin or the like. This negative characteristic thermistor 8 is supported on the inner surface side of the connector 12 with a sensor holder 9 interposed between the connector 12 and the sensor mounting plate 10. connector 1
2 is in contact with the outer periphery of the inner pot 4 and conducts the heat of the food to be heated, such as rice water, in the inner pot 4 to the negative characteristic thermistor 8 . 13 is a mounting base for fixing the sensor mounting plate 10 to the outer surface of the outer pot 2;
In order to prevent heat conduction to 0, it is made of resin or the like with poor heat conduction. 14 is a protrusion provided on the mounting base 13;
5 is a through hole provided in the mounting base 13, and 16 is a through hole provided in the side wall of the outer pot 2, into which the protrusion 14 is fitted. 17 is a through hole provided in the side wall of the outer pot 2 and communicates with the through hole 15. Reference numeral 18 denotes a through hole into which the protrusion 19 of the connector 12 is fitted, and is provided on the side wall of the outer pot 2. A rivet 20 is inserted into the through holes 17 and 15, and has a cylindrical shape with two stages of large and small diameters, with the tip 22 on the small diameter side.
The tip is divided into four parts, and by pushing in the push rod 21, a protrusion 23 provided on the inner surface of the tip 22 can be removed.
Due to the presence of , the four-divided portion expands outward as shown in FIG.
よつてセンサ取付板１０および取付台１３はリ
ベツト２０により外鍋２に固定される。 Therefore, the sensor mounting plate 10 and the mounting base 13 are fixed to the outer pot 2 by the rivets 20.
したがつて炊飯器の容量によつて外鍋２の透孔
１６，１７，１８を決定すればセンサ取付板１０
および取付台１３は同一種類の部品ですべての機
種に対応することができる。 Therefore, if the through holes 16, 17, 18 of the outer pot 2 are determined depending on the capacity of the rice cooker, the sensor mounting plate 10
The mounting base 13 can be made of the same type of parts and can be used with all models.
また炊飯器本体を従来のように逆にしてビスを
外す必要はなく、押込棒２１を引き抜くことによ
り負特性サーミスタ８を備えた取付板１０を外す
ことができる。 Further, there is no need to reverse the rice cooker body and remove the screws as in the conventional case, and the mounting plate 10 provided with the negative characteristic thermistor 8 can be removed by pulling out the push rod 21.
また普通の炊飯器の場合は設けられていない
が、ジヤー炊飯器の場合には設けられている断熱
材７は、センサ取付部のみを外鍋２より外すこと
になるから保温性能については従来の場合よりも
断熱効果を有効に使うことができる。 In addition, the heat insulating material 7, which is not provided in ordinary rice cookers but is provided in the case of jar rice cookers, is not as good as the conventional one in terms of heat retention performance because only the sensor attachment part has to be removed from the outer pot 2. The insulation effect can be used more effectively than in the case of
なおリベツト２０は、樹脂により構成すること
により熱伝導を少なくすることができるので、保
温性能の向上につながる。 Note that by forming the rivet 20 from resin, heat conduction can be reduced, leading to improved heat retention performance.
