TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dew receiving structure of a rice cooker (including a rice cooker).
[0002]
[Prior art]
When the lid is opened after the rice cooker has finished cooking rice, dew condensation adhering to the inner surface of the lid may flow down the inner surface of the lid and accumulate in the hinge at the rear of the main body of the rice cooker. It is well known that a rice cooker is provided with a dew receiving structure in order to prevent the dew from spilling outside. In recent years, in order to prevent such dew condensation from occurring, a lid heater is generally provided.However, in order to avoid an increase in product cost due to the provision of the lid heater, a small-capacity low-cost rice cooker is used. Adopts a structure in which only the above-mentioned dew receiving structure is provided without providing a lid heater. Patent Documents 1 to 3 show examples of conventionally known dew receiving structures.
[0003]
On the other hand, in order to make the rice cooker portable, an inverted U-shaped handle is attached to the left and right sides of the rice cooker body so as to be swingable, and is usually laid down on the rear side of the body. There is conventionally known an apparatus that is started up and carried (see Patent Document 4).
[0004]
Note that the portable rice cooker disclosed in Patent Document 4 does not have a dew receiving structure. In addition, the structure for supporting the handle that has been tilted backward has a structure in which a step is provided on the outer surface of the rice cooker main body, and the handle is placed on the step, and the support piece of the handle protrudes from the rear surface of the main body. It does not have a set configuration

[Problems to be solved by the invention]
With respect to the structure in which the dew receiving case is engaged with the main body in the dew receiving structures in Patent Documents 1 to 3, in the case of Patent Document 1, a leaf spring is attached to the dew receiving storage portion, and the side surface of the dew receiving case is attached. By pressing, a part of the other side surface is engaged with the main body. However, according to this configuration, a leaf spring is required, and there is a problem that the number of components increases.
[0007]
In the case of Patent Literature 2, since the dew receiving case is configured to be inserted into the storage portion from obliquely rear of the main body, it cannot be adopted when there is a protrusion such as a handle support piece above the storage portion.
[0008]
In the case of FIG. 3 of Patent Document 3, a convex portion provided on the left and right side pieces at the upper end of the dew receiving case and a concave portion provided on a cover screwed thereover are detachably engaged by bending. However, there is a problem that a cover, which is an independent component, is required to provide the concave portion for bending. Further, the one shown in FIG. 4 of the document is designed so that the groove of the dew receiving case is fitted to the horizontal guide rib on the main body side, but since it is a structure that slides in the front-rear direction, There is a problem of getting out without permission.
[0009]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a rice cooker provided with a handle, in which there is no increase in the number of components, and a dew receiving structure that can be easily locked.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention relates to a rice cooker main body, a lid attached to a hinge portion of the main body so as to be openable and closable, a handle slidably attached to left and right side surfaces of the main body, and the main body. A dew receiving case detachably attached to a rear surface of the main body, a support piece for supporting the handle, which is tilted rearward, is protruded from a rear surface of the main body, and a dew collecting groove including the hinge portion is formed on an upper surface of the main body. At the same time, a drain hole is provided at the bottom of the dew gathering groove at the hinge portion, a storage portion is provided below the drain hole toward the rear of the main body, and an open storage portion is provided at a lower portion of the support piece. In the dew receiving structure of the rice cooker in which the dew receiving case is housed, a configuration is provided in which a concave and convex engaging portion is provided between the lower surface of the support piece and the opposing surface of the dew receiving case so as to be mutually engaged and disengaged with a click feeling. .
[0011]
According to the above configuration, when the lid is opened after the rice cooking, the dew attached to the inner surface of the lid flows down into the dew collecting groove of the main body, and falls into the dew receiving case from the drain hole. When removing the dew receiving case, if a slight force is applied to pull it out rearward, the concave / convex engaging portion is disengaged, and is pulled rearward from the storage portion of the main body. Conversely, when the dew receiving case is mounted, if it is inserted into the storage portion from the rear of the main body and a slight force is applied, the concave / convex engagement portion engages with a click feeling and is held in the storage portion.
[0012]
It is possible to adopt a configuration in which the concave and convex engaging portions are mutually engaged and disengaged by bending. There is a merit that the design can afford only the dimensions to bend.
[0013]
Further, the dew receiving case has a rear end surface that is flush with the rear surface of the main body, and a case auxiliary portion that projects rearward within the width of the support piece is provided on the rear end surface. A configuration may be adopted in which the portion serves as a grip portion of the dew receiving case, and the above-mentioned concave and convex engaging portion is provided on the case auxiliary portion and a support piece facing the case auxiliary portion.
[0014]
Further, it is possible to adopt a configuration in which the hinge portion provided on the main body includes a pair of left and right hinge support portions, and the opening width of the dew receiving case is formed inside the left and right hinge support portions. Further, a configuration may be adopted in which the size of the dew collecting groove is formed so as to include the opening of the dew receiving case within the range of the drain hole provided in the dew collecting groove.
[0015]

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of the rice cooker as viewed obliquely from behind. As can be seen from this figure, the rice cooker comprises a main body 1, a lid 3 attached to a hinge portion 2 at a rear end thereof so as to be openable and closable, and an inverted U-shaped handle attached to both right and left sides of the main body 1 so as to swing. 4 and a dew receiving case 5 detachably attached to the rear surface of the main body 1. The handle 4 is mounted close to the upper edge 6 of the main body 1, and one side edge of the handle 4 substantially coincides with the upper edge 6 of the main body 1 in a state where the handle 4 is tilted backward (FIGS. 3 and 4B). reference). A support piece 7 for horizontally supporting the handle 4 tilted rearward is provided below the hinge portion 2 on the rear surface of the main body 1 so as to protrude rearward by integral molding. The support piece 7 is formed in a plate shape having a substantially semi-elliptical planar shape (see FIG. 4A). Below the support piece 7, a storage section 8 formed of a rectangular recess opened rearward is provided on the rear surface of the main body 1, and the dew receiving case 5 is removably stored from the rear.
[0016]
As shown in FIG. 3, a dew gathering groove 9 is formed near the hinge 2 on the upper surface of the main body 1, that is, behind the rice cooker 10. The dew gathering groove 9 is provided with a gentle slope so as to descend as it approaches the hinge part 2, and a drain hole 11 is provided at the bottom of the dew gathering groove 9 in the hinge part 2.
[0017]
As shown in FIG. 4 (a), the hinge portion 2 is formed in a U-shape with a transverse cross section opened forward, and has hinge support portions 2a, 2a on both left and right sides thereof. The lid 3 is attached to be openable and closable by a hinge shaft 12 inserted between 2a. The drain hole 11 has a rectangular shape surrounded by a U-shaped hinge portion 2, and a vertical passage 13 having a rectangular cross-sectional shape is provided inside the main body 1 (see FIG. 4B). ), The lower end of which is open to the upper surface of the storage section 8. A guide rib 14 in the front-rear direction is provided on the inner side surface at the boundary between the passage 13 and the storage portion 8, and regulates the upper end surface of the dew receiving case 5. Further, two guide ribs 15 in the front-rear direction are provided on the bottom surface of the storage section 8 to reduce frictional resistance when the dew receiving case 5 is inserted or pulled out. The drain hole 11 may be formed by a plurality of holes. In that case, only one passage 13 is provided in common to these holes. In either case of a single hole or a plurality of holes, these size relationships are set so that the opening of the dew receiving case 5 is included in the range of the opening.
[0018]
A case auxiliary portion 16 is provided on the rear end surface of the dew receiving case 5 to protrude rearward (see FIG. 2). The case auxiliary portion 16 has a U-shaped upper end edge 17 protruding rearward from the center of the rear end edge of the dew receiving case 5, and its depth is approximately half the depth of the dew receiving case 5. , Open upward and inward. With the dew receiving case 5 stored in the storage part 8, the depth of the storage part 8 and the width of the dew receiving case 5 in the front-rear direction are set such that the rear end face is flush with the rear end face of the main body 1. The case auxiliary portion 16 protrudes from the rear end surface of the main body 1, and the amount of protrusion is formed so as to fall within the range of the size of the support piece 7 in a plane. The case assisting portion 16 protruding from the rear end surface of the main body 1 serves as a grip portion, and the dew receiving case 5 can be gripped by pinching both side surfaces thereof with fingertips.
[0019]
The lower surface of the support piece 7 and the upper edge of the case auxiliary portion 16 are vertically opposed to each other, and a pair of convex portions 18 are formed on both upper side edges of the case auxiliary portion 16 and are opposed to this. A pair of recesses 19 are formed on the support piece 7 side. The recess 19 is formed by a bending portion 21 formed by thinning a part of the support piece 7 and a hole 22 formed between the bending portion 21 and the rear end surface of the main body 1 (FIG. 4C). )reference). When the dew receiving case 5 is inserted into the storage portion 8, the convex portion 18 pushes up the bending portion 21 and advances, and is engaged with the hole 22 with a click feeling, thereby preventing the dew receiving case 5 from falling out. Can be The projections 18 and the depressions 19 form an uneven engagement portion.
[0020]
The bending part 21 may be provided on the case auxiliary part 16 side as shown in FIG. In this case, the convex portion 18 is formed at the tip of the bending portion 21, and the concave portion 19 on the support piece 7 side is formed only by the hole 22.
[0021]
The presence of the bending portion 21 has an advantage that the design of the concave-convex engaging portion can have a margin, but if the molding accuracy is controlled to be high, the bending portion 21 is omitted, and the convex portion 18 and the hole 22 or the convex portion 18 are formed. The concave-convex engagement portion may be formed by a simple concave portion.
[0022]
As shown in FIG. 4B, the opening width of the storage portion 8 is formed to have a width equal to the interval L between the hinge support portions 2a, 2a. In addition, as shown in FIG. 5A, when the interval L between the hinge portions 2 is formed to be relatively larger than the opening width of the storage portion 8, and the opening width is formed so as to be included in the range of the interval L. There is also. On the other hand, as shown in FIG. 5B, when the opening width of the storage portion 8 is larger than the interval L between the hinge portions 2, the gold is provided between the upper portion of the storage portion 8 and the bottom surface of the dew gathering groove 9. Since the thick portion 23 (so-called “wall”) is generated due to the technology of the molding, there is an inconvenience of causing sink marks. Therefore, it is desirable that the width of the opening of the storage portion 8 is formed so as to match or be included in the interval L of the hinge portion 2.
[0023]
The rice cooker according to the embodiment is as described above. When the lid 3 is opened after the rice is cooked, the dew on the inner surface of the rice cooker flows down into the dew collecting groove 9, passes through the drain hole 11 through the passage 13, and enters the dew receiving case 5. Fall. In order to remove the dew accumulated in the dew receiving case 5, the user grips both side surfaces of the case assisting portion 16 with a fingertip and applies a slight force, and the convex portion 18 comes out of the hole 22, disengages and engages. The receiving case 5 can be extracted. When returning the empty dew receiving case 5 to its original state, when it is inserted into the storage part 8, the convex part 18 bends the bending part 21 and engages with the hole 22 with a click feeling. The case 5 is held in a retaining state.
