BACKGROUND 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, the condensation that has adhered to the inner surface of the lid may flow down the inner surface of the lid and accumulate on the hinge portion at the rear of the main body of the rice cooker. In order to prevent this dew from spilling outside, it is well known in the art to provide a dew receiving structure in the rice cooker. In recent years, a lid heater is generally provided in order to prevent such condensation from occurring, but in a rice cooker with a small capacity and a low price in order to avoid an increase in product cost due to the provision of the lid heater. Adopts a structure in which only the above-mentioned dew receiving structure is provided without providing a lid heater. An example of a conventionally known dew receiving structure is shown in Patent Documents 1 to 3.
[0003]
On the other hand, in order to make the rice cooker portable, inverted U-shaped handles are swingably attached to the left and right sides of the main body of the rice cooker, and are usually tilted to the rear side of the main body. In the past, there has been known one that is configured to be carried and carried (see Patent Document 4).
[0004]
In addition, the portable rice cooker shown by the said patent document 4 is not equipped with the dew receiving structure. In addition, the structure that supports the handle that has been tilted rearward has a structure in which a step is provided on the outer surface of the main body of the rice cooker, and the handle is placed on the step. The support piece of the handle protrudes from the rear surface of the main body. The configuration is not set

[Problems to be solved by the invention]
In the dew receiving structure in Patent Documents 1 to 3, in view of the structure for engaging the dew receiving case with the main body, in the case of Patent Document 1, a leaf spring is attached to the dew receiving storage part, By pressing, a part of the other side surface is engaged with the main body side. However, according to this configuration, a leaf spring is required, which causes a problem of increasing the number of parts.
[0007]
In the case of Patent Document 2, since the dew receiving case is inserted into the storage portion from obliquely behind the main body, it cannot be adopted when there is a protruding portion such as a handle support piece at the upper portion of the storage portion.
[0008]
In the case of FIG. 3 of Patent Document 3, the convex portions provided on the left and right side pieces at the upper end of the dew receiving case and the concave portions provided on the cover screwed thereon are detachably engaged by bending. However, there is a problem that a cover which is an independent part is required in order to provide a concave recess for bending. In addition, what is shown in FIG. 4 of the same document is adapted to fit the groove of the dew receiving case to the horizontal guide rib on the main body side, but is a structure that slides in the front-rear direction. There is a problem of getting out without permission.
[0009]
Then, this invention makes it a subject to provide the dew receiving structure which did not increase of components and was able to be easily latched in the rice cooker provided with the handle.
[0010]
[Means for Solving the Problems]

And providing a drainage hole at the bottom of the dew collecting groove in the hinge part, and providing a storage part below the drainage hole toward the rear of the main body and opened at the lower part of the support piece. In the dew receiving structure of the rice cooker that houses the dew receiving case, a configuration is adopted in which an uneven engagement part that engages and disengages with a click feeling is provided between the lower surface of the support piece and the opposing surface of the dew receiving case. .
[0011]
According to said structure, if a cover is opened after rice cooking completion, the dew condensation adhering to the inner surface will flow down into the dew collecting groove of a main body, and will fall in a dew receiving case from a drainage hole. When removing the dew receiving case, if a slight force is applied to pull the dew receiving case backward, the concave / convex engaging portion comes off and is pulled backward from the housing portion of the main body. When the dew receiving case is mounted, conversely, when a slight force is applied by inserting the dew receiving case from the rear side of the main body, the concave / convex engaging portion is engaged with a click feeling and held in the storage portion.
[0012]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of the rice cooker as viewed obliquely from the rear. As can be seen from this figure, the rice cooker has a main body 1, a lid 3 attached to the hinge 2 at the rear end thereof so as to be freely opened and closed, and an inverted U-shaped handle attached to both the left and right sides of the main body 1 so as to be swingable. 4 and a dew receiving case 5 detachably attached to the rear surface of the main body 1. The handle 4 is attached 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 when tilted rearward (FIGS. 3 and 4B). reference). Further, a support piece 7 for horizontally supporting the handle 4 tilted backward 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 portion 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 detachably stored from the rear.
[0016]
As shown in FIG. 3, a dew collecting groove 9 is formed on the upper surface of the main body 1 in the vicinity of the hinge portion 2, that is, behind the rice cooking pot 10. The dew collecting groove 9 has a gentle slope so as to descend as it approaches the hinge portion 2, and a drain hole 11 is provided at the bottom of the dew collecting groove 9 in the hinge portion 2.
[0017]
As shown in FIG. 4 (a), the hinge portion 2 is formed in a U-shape whose cross section is opened forward, and has hinge support portions 2a and 2a on both left and right sides thereof. The lid 3 is attached to be freely opened and closed by a hinge shaft 12 inserted between 2a and 2a. The drainage hole 11 has a rectangular shape surrounded by a U-shaped hinge portion 2, and a longitudinal passage 13 having a rectangular cross-sectional shape is provided inside the main body 1 (see FIG. 4B). ), And the lower end is opened to the upper surface of the storage portion 8. A guide rib 14 in the front-rear direction is provided on the inner side surface of the boundary portion between the passage 13 and the storage portion 8 to restrict 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 portion 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 with these holes. In either case of a single hole or a plurality of holes, the size relationship is 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 protruding rearward is provided on the rear end surface of the dew receiving case 5 (see FIG. 2). The case auxiliary portion 16 has a U-shaped upper edge 17 protruding rearward from the center of the rear edge of the dew receiving case 5, and the depth thereof is substantially half of the depth of the dew receiving case 5. , Open upward and inward. In a state where the dew receiving case 5 is stored in the storage unit 8, the depth of the storage unit 8 and the width in the front-rear direction of the dew receiving case 5 are set so that the rear end surface thereof is flush with the rear end surface of the main body 1. The case auxiliary portion 16 protrudes from the rear end surface of the main body 1, and the protrusion amount is formed so as to be within the range of the size of the support piece 7 in a plan view. The case auxiliary 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 with fingertips.
[0019]
The lower surface of the support piece 7 and the upper edge of the case auxiliary portion 16 are close to each other and face each other, and a pair of convex portions 18 are formed on both side edges of the upper portion of the case auxiliary portion 16, and face each other. A pair of recesses 19 is formed on the support piece 7 side. The concave portion 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 part 8, the convex part 18 pushes up the bending part 21 and is engaged with the hole 22 with a click feeling, thereby preventing the dew receiving case 5 from coming off. It is done. The convex and concave portions 18 and the concave portions 19 form a concave and convex engaging 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]
If there is a bending part 21, there is an advantage that there is a margin in the design of the concave-convex engaging part, but when the molding accuracy is managed with high accuracy, the bending part 21 is omitted, and the convex part 18 and the hole 22 or the convex part 18 The concave / convex engaging 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 with a width equal to the interval L between the hinge support portions 2a and 2a. In addition, as shown in FIG. 5A, the interval L of the hinge portion 2 is formed to be relatively larger than the opening width of the storage portion 8, and the opening width is included in the range of the interval L. There is also. On the other hand, as shown in FIG. 5 (b), when the opening width of the storage portion 8 is larger than the interval L of the hinge portion 2, the metal between the upper portion of the storage portion 8 and the bottom surface of the dew collecting groove 9 Since the thick part 23 (so-called “thickening”) is generated due to the molding technique, there is a disadvantage that causes sink marks. Therefore, it is desirable to form the opening width of the storage portion 8 so as to coincide with or be included in the interval L of the hinge portion 2.
[0023]
The rice cooker of the embodiment is as described above. When the lid 3 is opened after the completion of rice cooking, the dew condensation on the inner surface flows down to the dew collecting groove 9 and enters the dew receiving case 5 from the drain hole 11 through the passage 13. Fall. In order to eliminate the dew accumulated in the dew receiving case 5, if a slight force is applied by pinching both side surfaces of the case auxiliary portion 16 with a fingertip, the convex portion 18 comes out of the hole 22 and is disengaged to release the dew. The receiving case 5 can be extracted. When returning the empty dew receiving case 5 to the original state, when the dew receiving case 5 is inserted into the storage portion 8, the convex portion 18 bends the bending portion 21 and engages the hole 22 with a click feeling. The case 5 is held in a retaining state.
[0024]
【The invention's effect】
As described above, the present invention has a configuration in which a concave and convex engaging portion that engages and disengages with a click feeling is provided between the lower surface of the support piece that supports the handle that is tilted backward and the opposing surface of the dew receiving case. The dew receiving case can be stored and retained in the rice cooker main body in a non-detaching state without adding parts. Further, a bending function can be added to the concave-convex engaging portion without using another component such as a spring.
[0025]
If the opening of the storage portion is set so as to be included inside the hinge support portion (including the case where it coincides with the interval of the hinge support portion), there is no problem in the molding technique and a good finish can be obtained.
