  A predetermined amount of water (cooling water) can be stored inside the water tank 20, and the generated steam is condensed, liquefied and recovered. Here, although the case where the water tank 20 is arrange | positioned at the front side of the lower housing | casing 11 is shown as an example, it is not limited to this. Both ends of the steam conduit 30 are opened, one end communicates with the inner lid 13 (small hole of the inner lid 13), and the other end communicates with the water tank 20, so that the steam generated in the inner pot 21 is conducted to the water tank 20. It is something to be made. The steam conduit 30 may be configured to communicate with a plurality of conduits. The vapor conduit 30 is preferably detachable from the upper lid 12 for maintenance and cleaning.

  FIG. 3 is an explanatory diagram for explaining the position of the center of gravity when viewed from the side surface of the rice cooker 100. Based on FIG. 3, the position of the center of gravity of the rice cooker 100 is such that the heated object 1 is accommodated and water is stored, and the heated object 1 is not accommodated and no water is accumulated. The state will be described as an example. FIG. 3A shows a state in which the maximum amount of the object to be heated 1 is accommodated in the inner pot 21 and the maximum amount of water is stored in the water tank 20, and FIG. The state to which the to-be-heated material 1 is not accommodated is shown, and the water is not stored in the water tank 20, respectively.

FIGS. 3 (a) in the center of gravity of the entire rice cooker 100 A ₁ is accommodated article to be heated 1 and water the maximum amount, the upper lid 12 B is fitted with the inner lid 13 and the vapor conduit 30 for example ( The center of gravity position of the lower housing 11 of about 1.0 kg, for example, about 2.1 kg, and the heated object 1 of about 2.1 kg in the inner pan 21 of about 0.4 kg of D _1, for example. The center of gravity of the entire inner pan 21 in the accommodated state, E is the center of gravity of the control board 31 of, for example, about 0.5 kg, F is the center of gravity of the heating means 32 of, for example, about 1.0 kg, and G ₁ is, for example, about The center-of-gravity positions of the entire water tank 20 in a state where about 1.0 kg of water is stored in the 0.5 kg water tank 20 are shown.

In FIG. 3 (b), the cooker 100 of the center of gravity of the whole position A ₂ is not accommodated article to be heated 1 and water, the center of gravity of the inner bowl 21 in D _2, for example, about 0.4 kg, G ₂ is For example, the center of gravity of a water tank 20 of about 0.5 kg is shown. Note that B, C, E, and F are the same as those in FIG. As can be seen from FIG. 3, the center of gravity A ₁ of the rice cooker 100 in a state where the maximum amount of the heated object 1 is accommodated in the inner pot 21 and the maximum amount of water is stored in the water tank 20 is the heated object 1. Is located in the front side of the rice cooker 100 as compared with the gravity center position A ₂ of the rice cooker 100 in a state where the water is not stored in the water tank 20.

  When the rice cooker 100 is carried in a state where the maximum amount of the heated object 1 is accommodated in the inner pot 21 and the maximum amount of water is stored in the water tank 20, the heated object 1 is transferred from the inner pot 21. The possibility of leakage from the water tank 20 increases. When the heated object 1 and the water leaks inside the lower housing 11, or worse soil the inside lower housing 11, so that the or gets wet. If it does so, it will cause the damage of electrical components, such as a control board, and the deterioration of the sanitary surface inside the lower housing | casing 11. Therefore, in Embodiment 1, the handle 35 (main body handle portion) is attached to a position in consideration of safety when carrying the rice cooker 100 (described in detail in FIG. 4).

  FIG. 4 is an explanatory diagram for explaining the attachment position of the handle 35 provided in the lower housing 11. Based on FIG. 4, will be described in detail how to determine the mounting position of the handle 35 is a feature of the first embodiment (predetermined positions of both sides of the lower housing 11). On both sides of the lower housing 11 constituting the main body 10 of the cooker 100, rotatably configured handle 35 is adapted to be mounted along its sides. This handle 35 functions as a handle when carrying the rice cooker 100.

  In FIG. 4, the upper stage ((a), (b) and (c)) of the rice cooker 100 in which the maximum amount of heated object 1 is accommodated in the inner pot 21 and the maximum amount of water is stored in the water tank 20. The handle 35 (rotation fulcrum of the handle 35) is attached at a predetermined position, and the state when the rice cooker 100 is lifted is shown in the lower stage ((d), (e) and (f)) in the inner pot 21 and the object 1 to be heated. The state at the time of attaching the handle | steering-wheel 35 to the predetermined position of the rice cooker 100 which is not accommodated and the water is not stored in the water tank 20, and raised the rice cooker 100 is each shown. As described with reference to FIG. 3, the position of the center of gravity of the rice cooker 100 as a whole changes depending on whether the object to be heated 1 is accommodated and whether water is stored. The determination of the attachment position of the handle 35 will be described with reference to the case where the handle 35 is attached to these barycentric positions.

4A shows a state when the handle 35 is attached to A ₂ (see FIG. 3B) and the rice cooker 100 is lifted, and FIG. 4B shows A ₁ (see FIG. 3A). When the handle 35 is attached and the rice cooker 100 is lifted, when the handle 35 is attached to a position above the A _{1 in} FIG. 4C on the vertical line of A ₁ and the rice cooker 100 is lifted. Each state is shown. These are heated object 1 is accommodated in rice cooker 100 water is stored is on a vertical line of A ₁ or A _1, by attaching the handle 35 to the position where the upper side of the A _1, Even if the rice cooker 100 is lifted, it can be kept horizontal and stable. On the other hand, by attaching the handle 35 to the A _2, gradient larger on the front side when lifted cooker 100, it can be seen that not stable.

4 (c) shows the state when the handle 35 is attached to A ₂ and the rice cooker 100 is lifted, and FIG. 4 (d) shows the state when the handle 35 is attached to A ₁ and the rice cooker 100 is lifted. Figure 4 (e) is on the vertical line of a _1, shows a handle 35 attached to a position where the upper side of the a _1, the state at the time of lifting the rice cooker 100, respectively. These not been heated object 1 is accommodated in rice cooker 100 water is not stored, by attaching the handle 35 to the A _2, it can be seen that the stable lift the rice cooker 100. On the other hand, by attaching the handle 35 to the A _1, large inclination on the rear side when lifted cooker 100, it can be seen that not stable. Further, on the vertical line of A _1, by attaching the handle 35 to the position where the upper side of the A _1, it can be seen that slightly tilts upon lifting the rice cooker 100.

  In the rice cooker 100 in which the article to be heated 1 is not accommodated and water is not stored, the inside of the lower housing 11 is not soiled or wetted even if it is slightly inclined. Since the water tank 20 is accommodated in the lower housing | casing 11, if the rice cooker 100 is carried in the state where water is stored, there exists a possibility that water may overflow. If water overflows from the aquarium 20, not only will the safety of the control device or the like be lost, but also germs will propagate there, and hygiene will be lost. Therefore, the stability when lifting the rice cooker 100 in which the article to be heated 1 is accommodated and water is stored is more important.

Therefore, the cooker 100, the position shown in FIG. 4 (c) and (f), i.e., on the vertical line of A _1, a handle 35 attached to the upper a position than A _1, consideration to safety and hygienic properties It is supposed to be. In other words, the rotation fulcrum of the handle 35 is attached on the vertical line passing through A ₁ and above A ₁ . Therefore, even in the state where the heated object 1 is accommodated in the inner pot 21 and the water is stored in the water tank 20, the rice cooker 100 can be stably moved with the handle 35. . The attachment position of the handle 35 is preferably on the vertical line, but may be slightly deviated from the vertical line as long as it is within an allowable range.

In addition, since the handle 35 is attached at a position above A ₂ , the predetermined inclination can be maintained even when the heated object 1 is not accommodated and water is not stored. , Stability is not reduced. In other words, even when the heated object 1 is not accommodated in the inner pot 21 and the water is not stored in the water tank 20, the rice cooker 100 is stable in a state of being almost horizontal with the handle 35. Can be moved to.

  Also, when brought into position of the handle 35 in the vertical direction, the handle 35 may be provided with a lock mechanism for restricting rotation along the sides of the cooker 100. Then, since the fulcrum of rotation of the rice cooker 100 is not the attachment position of the handle 35 but the position where the handle 35 is gripped becomes the fulcrum of rotation of the rice cooker 100, the inclination when the rice cooker 100 is lifted is made smaller. can do. In addition, the handle | steering-wheel 35 does not specifically limit the shape, a magnitude | size, a material, etc., What is necessary is just what a user can hold and lift the rice cooker 100. FIG.

Embodiment 2. FIG.
FIG. 5 is a schematic diagram for explaining a rice cooker 200 according to the second embodiment. FIG. 6 is a perspective view for explaining the rice cooker 200. Based on FIG.5 and FIG.6, the characteristic matter of the rice cooker 200 which concerns on Embodiment 2 is demonstrated in detail. In the second embodiment, differences from the first embodiment will be mainly described, and the same parts as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted. The rice cooker 200 according to the second embodiment is configured such that the water tank 20 can be easily attached and detached. 5 and 6 show an example in which the water tank 20 is accommodated on the front surface side of the lower housing 11.

  FIG. 5A shows a schematic longitudinal sectional view in a state where the upper lid 12 is closed, and FIG. 5B shows a schematic longitudinal sectional view in a state where the upper lid 12 is opened. As shown in FIG. 5, the water tank 20 is supported in the accommodation space 22 of the lower housing 11 by an elastic body 51 that urges the water tank 20 from the lower direction to the upper direction. That is, the water tank 20 is always pushed upward. And the water tank 20 is hold | maintained in the predetermined position by the fixing device 52 (FIG. 5 (a) and FIG. 6 (a)). The fixing device 52 is provided in a part of the upper part of the water tank 20 and is configured to restrict and release the upward movement of the water tank 20 by being inserted into and removed from a recess 53 formed on the lower housing 11 side. .

  And the restriction | limiting of the movement of the upper direction of the water tank 20 is cancelled | released, ie, the fixing device 52 is extracted from the recessed part 53, the water tank 20 moves upwards (pops up), and the upper end part of the water tank 20 is the lower housing | casing 11. (Fig. 5 (b) and Fig. 6 (b)). That is, the rice cooker 200 can easily hold the water tank 20 in the lower housing 11 and can be easily detached from the lower housing 11. The fixing device 52 is preferably operable only when the upper lid 12 is opened. That is, it is preferable that the fixing device 52 is installed inside the lower housing 11 so that the water tank 20 can be attached and detached only when the upper lid 12 is opened.

  If it does in this way, it will become impossible to remove the water tank 20 accidentally during the rice cooking operation of the rice cooker 200, etc., and only the water tank 20 will come off and an accident that steam will be exhausted outside the rice cooker 200 unexpectedly. Can be prevented. Therefore, safety is improved and convenience is improved. Further, the restriction and release of the movement of the water tank 20 in the upper direction by the fixing device 52 may be interlocked with the opening and closing of the upper lid 12. For example, when the upper lid 12 is closed, the water tank 20 is pushed into the upper lid 12, the fixing device 52 is inserted into the concave portion, the movement in the upper direction is restricted, the holding space 22 is held, and the upper lid 12. When opening the door, it is preferable that the restriction is released and the head is moved upward. In this way, safety and convenience can be further improved.

  Further, a protrusion (flange) 55 that locks around the opening of the lower housing 11 is formed on the periphery of the upper end of the water tank 20. This is because the protrusion 55 provided on the periphery of the upper end of the water tank 20 is in contact with the periphery of the opening of the lower housing 11 while the water tank 20 is being held, so that the water tank 20 can be taken out more easily. That is, when the holding state of the water tank 20 is released, the water tank 20 is moved upward by the elastic body 51, and the protrusion 55 is separated from the periphery of the opening of the lower housing 11. Since the user can grasp the water tank 20 through the projection 55, the convenience is greatly improved. Further, the protrusion 55 can also function as a slip stopper. In addition, it may comprise so that the upper surface of the water tank 20 may be covered with a cover part, and the projection part 55 may be formed in a cover part. Moreover, the protrusion part 55 may be formed in a part of upper end part periphery of the water tank 20, and may be formed in all.

  The water tank 20 may be made of a transparent material. This is because if the water tank 20 is made of a transparent material, the state of dirt inside the water tank 20 can be easily recognized, and the cleaning performance can be greatly improved. Also, a resin material in which a certain amount of antibacterial material or sterilizing material (for example, silver or guanidine-based material) is mixed with the lid of the water tank 20 and the steam conduit 30 that is submerged in the water that is extended and stored in the water tank 20. It is good to comprise. In this way, it is not necessary to mix the antibacterial material or the sterilizing material into the water tank 20 main body, and the transparency of the water tank 20 main body is not impaired. Therefore, the propagation of bacteria in the water tank 20 can be suppressed, the visibility in the water tank 20 can be maintained, and convenience is greatly improved. Note that only one of the lid of the water tank 20 or the steam conduit 30 may be made of a resin material mixed with an antibacterial material or a sterilizing material.

  FIG. 7 is an explanatory diagram for explaining an example of the accommodation space 22 of the lower housing 11. Based on FIG. 7, an example of the accommodation space 22 of the lower housing | casing 11 is demonstrated in detail. FIG. 7A is a perspective view showing a state in which the front side of the lower housing 11 is viewed from above, and FIG. 7B is a schematic longitudinal sectional view of the rice cooker 200 showing a state in which the upper lid 12 is closed. FIG. 7C shows a schematic longitudinal sectional view of the rice cooker 200 showing a state where the upper lid 12 is opened. As described in the first embodiment, when water leaks into the lower housing 11, the inside of the lower housing 11 is wetted. This increases the possibility of damage to electrical components such as the control board. Then, even if water leaks from the water tank 20, the through-hole part 56 is formed in the accommodation space 22 bottom face of the lower housing | casing 11 so that it can drain to the rice cooker 200 exterior.

  The through-hole portion 56 is preferably formed with an opening area larger than that of the rice grain. If it does so, while being able to drain the leaked water, even if the to-be-heated object 1 and garbage enter into the accommodation space 22 of the lower housing | casing 11 in the state which removed the water tank 20, the to-be-heated object 1 or the Garbage and the like can be easily removed out of the rice cooker 200 (lower housing 11), and the cleanability is improved. In addition, it is good to set it as the opening area which can prevent entry of an insect etc. Further, a mesh filter or the like may be provided in the through-hole portion 56 to prevent insects and the like from entering.

  FIG. 8 is a longitudinal sectional view of the rice cooker 200 showing a state in which the upper end portion of the water tank 20 is inclined. Based on FIG. 8, the shape of the water tank 20 is demonstrated. In FIG. 8, the upper end portion of the water tank 20 is inclined so as to face downward toward the front side. In other words, the height of the wall surface of the rear side of the tub 20 (back side), with each other to greater than the height of the wall surface of the front side (front side). By carrying out like this, it can be made to leak to the front side of the water tank 20, and it considers safety more. Further, a notch may be formed in the front side wall surface of the water tank 20 so that water leaks to the front side of the water tank 20.

  FIG. 9 is an explanatory diagram for explaining another example of the accommodation space 22 of the lower housing 11. Based on FIG. 9, another example of the accommodation space 22 of the lower housing 11 will be described in detail. 9A is a schematic longitudinal sectional view showing a state where the water reservoir 57 is installed, and FIG. 9B is a schematic longitudinal sectional view showing a state where the water reservoir 57 is moved upward. Yes. As shown in FIG. 9, a recess 58 in the receiving space 22 the bottom surface of the lower housing 11, so as to detachably mount the puddle 57 in the recess 58.

  That is, instead of forming the through-hole portion 56, a recess 58 is formed, and the water reservoir 57 is attached to the recess 58 so that the water reservoir 57 receives water leaked from the water tank 20. Since the water reservoir 57 is detachable from the recess 58, the water reservoir 57 can be removed when the received water has accumulated a predetermined amount, and the received water can be discarded. Therefore, the parts other than the water reservoir 57 are not wetted and the safety is taken into consideration. Moreover, since the water pool part 57 is also detachable, it can be cleaned as appropriate, and the cleanability is not deteriorated. Although not shown, the control board or the like if so provided at a position away from the receiving space 22 of the lower housing 11, can be provided with further safety considerations.

  FIG. 10 is an explanatory diagram for explaining a position where a note is attached. Based on FIG. 10, a description will be given of the attachment position of a caution note (here, “high temperature caution display”) for alerting the user. 10A is a perspective view showing a state in which the upper lid 12 is closed, and FIG. 10B is a perspective view showing a state in which the upper lid 12 is opened. The cautionary note must be affixed in the vicinity of the steam outlet and is generally affixed to the upper surface of the upper lid 12. However, since the rice cooker 200 collects the steam in the water tank 20, the steam is not discharged from the upper lid 12. Therefore, the rice cooker 200 can attach a precautionary note to a predetermined position on the upper surface of the water tank 20 (a position on the lower surface side of the upper lid 12 that cannot be seen when the upper lid 12 is closed).

  If a note is attached to the appearance of the rice cooker 200, that is, the upper surface of the upper lid 12, the design is greatly impaired.
