Further, a reinforcing rib 1d is provided between the auxiliary wall 1b and the auxiliary wall 1c, and a reinforcing rib continuous with the inner surface of the outer peripheral wall 1a is not formed between the auxiliary wall 1b and the outer peripheral wall 1a . Thus, it is possible to have stable well firmly increased strength of the reinforcing walls 1b and 1c are, to avoid "shrinkage" occurs in entailment body 1 outer peripheral wall 1a for molding the reinforcing ribs 1d, body 1 is prevented from impairing the appearance.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a handle structure of a main body in a cooker according to the present invention will be described with reference to the accompanying drawings in which the embodiment is applied to a hot plate.
FIG. 1 is a longitudinal sectional view of the entire hot plate, and FIG. 2 is an exploded perspective view of the hot plate shown in FIG. In the hot plate shown in FIGS. 1 and 2, a dish-shaped heat shield plate 2 is detachably mounted on a main body 1, a heater 3 is fixedly mounted on the heat shield plate 2, and cooking is performed above the heater 3. The body 4 is to be arranged.
[0008]
The main body 1 can be integrally formed of a synthetic resin material or the like. The heat-insulating plate 2 and the cooked body 4 are housed in the body 1 that is integrally molded, and the outer peripheral portion that is easy to touch with human hands is hardly heated. That is, the main body 1 formed in a dish shape for accommodating the heat shield plate 2 and the cooked body 4 has an outer peripheral wall 1a which is continuous at the upper end and which appears as an external appearance. At this time, the outer peripheral wall 1a is formed in a hakama shape whose lower part is opened, thereby enabling integral molding with a synthetic resin material. The structure of the synthetic resin hot plate main body having the guard function by the outer peripheral wall 1a is conventionally known and widely used, and is called a main body or a main body guard.
[0009]
As shown in FIG. 3, two auxiliary walls 1b and 1c are molded inside the outer peripheral wall 1a in parallel with the outer peripheral wall 1a at both left and right ends in the longitudinal direction, as shown in FIG. By holding the outer peripheral wall 1a and the two auxiliary walls 1b and 1c by hand, a handle portion having a soft contact with the fingers is formed. Further, a reinforcing rib 1d is provided between the two auxiliary walls 1b and 1c which are formed in parallel with the outer peripheral wall 1a, so that the handle has strength and a sense of stability. The reinforcing rib 1d in the illustrated example is formed between the auxiliary walls 1b and 1c, and is not formed between the outer peripheral wall 1a of the main body 1 and the auxiliary wall 1b. As a result, the influence of "sink" generated at the time of molding does not appear on the surface of the outer peripheral wall 1a, and the appearance of the main body 1 is not spoiled.
[0010]
In order to make the heat shield plate 2 detachable from the main body 1, in the hot plate in the illustrated example, the legs 5 project from the back surface of the heat shield plate 2 so that the legs 5 fit into the recesses 6 formed in the main body 1. I have. The heater 3 is fixed to the upper surface of the heat-insulating plate 2 formed in a dish shape by the metal fitting 7 so that the cooked body (plate) 4 disposed above the heater 3 can be heated. The electrode portion of the heater 3 fixed to the heat shield plate 2 penetrates the side wall 2 a of the heat shield plate 2, protrudes out of the device, and is provided with a plug receiver 8 and a temperature controller 9. The power is supplied, and the temperature of the cooked body 4 is detected by the heat-sensitive bar 10 of the temperature controller 9 so that the temperature of the cooked body 4 can be maintained at a desired set temperature. Handles 11 and 11 are mounted at opposed positions in the longitudinal direction of the cooking body 4.
[0011]
Steps 12, 12 are formed at opposite positions in the longitudinal direction of the main body 1 so that the handles 11 fixed to the cooking body 4 can fit into the main body 1 without floating. Further, a convex portion 13 is formed on the inner side surface of the step portion 12, and the convex portion 13 is engaged with a concave portion 14 formed on the handle 11, so that the cooking body 4 intersects with the handle 11 (vertical direction). I try not to move. As a result, the cooking body 4 can always be attached to the fixed position of the main body 1, the clearance between the cooking body 4 and the main body 1 can be maintained at a predetermined interval over the entire circumference, and when the cooking body 4 approaches, Abnormal heating of only a part of the main body 1 is eliminated.
[0012]
Since the heater 3 is fixed to the heat shield plate 2, the heat shield plate 2 and the heater 3 are integrally attached and detached. That is, as described above, the heater 3 is also mounted by fitting the leg 5 of the heat shield plate 2 into the recess 6 of the main body 1, but simply fitting the leg 5 into the recess 6 is sufficient. Not stable. Therefore, the engagement step 15 is further formed on a part of the step 12 of the main body 1, and the plug 3 of the heater 3 is fitted therein to stabilize the heater 3 at a fixed position. Specifically, the ridges 16, 16 are vertically provided on the side surface of the plug receiver 8. The protrusion 16 is stabilized by being inserted from above into the concave groove 17 vertically provided on the side surface of the engagement step portion 15.
[0013]
As the specific shape of the convex portion 13 formed in the step portion 12 and the concave portion 14 of the handle 11 that engages with the convex portion 13, in the illustrated embodiment, a projecting convex portion 13 is provided at the center of the lower end of the step portion 12 of the main body 1. The concave portion 14 which is formed and engages with the convex portion 13 is formed as a cutout portion which is a lower end portion of the side surface of the handle 11 and from the inside to the central portion thereof is deleted. Therefore, when the left and right grips 11 are fitted into the steps 12, respectively, the cooked body 4 is positioned and mounted without deviation without rattling or free movement.
[0014]
In addition, in the drawing, reference numeral 18 denotes a downward stick-like projection formed on a part of the handle 11, which is inserted into the set hole 19 of the plug receiver 8 when the cooking body 4 is mounted, and the projection 18 is inserted. The temperature controller 9 can be mounted. The projections 18 formed on the handle 11 are formed on both handles so that the cooking body 4 can be used regardless of the direction in which it is mounted. For this reason, a recess 20 in which the projection 18 is fitted is formed in the step 12 on the side where the plug cover 8 is not located. The fitting between the projection 18 and the recess 20 is also effective as an engagement means between the main body 1 and the cooking body 4.
[0015]
The hot plate described above can separate the main body 1, the heat shield plate 2 on which the heater 3 is set, and the cooking body 4 from each other for cleaning and other handling, and reliably maintain a predetermined positional relationship in a combined state. It is set and can be used for cooking. During or immediately after cooking, there is a possibility that the cooked body 4 may be carried in a hot state. The cooked body 4 may be carried only, or the entire cooker may be carried. Handle by holding the handle 11 of No. 4.
[0016]
On the other hand, when carrying the entire hot plate or the main body 1 from which the cooked body 4 is removed, the user handles the main body 1 formed in a hakama shape with his / her finger on the lower end of the outer peripheral wall 1a. As shown in FIG. 3, auxiliary walls 1b and 1c are arranged inside the outer peripheral wall 1a at the lower end of the outer peripheral wall of the main body 1, particularly at both left and right ends which are assumed to be handle portions. Therefore, the load of the entire hot plate applied when lifting is applied to the finger where the lower end surface of the outer peripheral wall is in contact with the lower end surfaces of the auxiliary walls 1b and 1c. That is, since the load of the hot plate is dispersed and applied to the fingers, even if the outer peripheral wall 1a is thin, it can be carried without causing pain to the fingers. In this case, the auxiliary wall is more effective by a plurality auxiliary walls 1b and Ri is Na large strength of the entire handle portion by reinforcing ribs 1d between the auxiliary wall 1c is provided, carrying with confidence it is Ru can be.
[0017]
Although the hot plate in the illustrated example has a square shape, a cooker such as a hot plate or an electric pan often uses a round shape. Further, those in which a heat shield plate and a heater are fixed to a main body are widely used. Therefore, the present invention can be widely used as the main body structure of such a cooking device.
[0018]
【The invention's effect】
According to the handle structure of the main body of the cooking device according to the first aspect of the present invention, the outer peripheral wall of the main body is formed in a skirt shape, and cooking such as a hot plate for accommodating a cooking body or a heat shield plate in an inner portion than the outer peripheral wall is performed. In the case of carrying the container with the fingers placed on the lower end of the outer peripheral wall of the main body, even if the outer peripheral wall is thin, the load applied to the fingers is distributed to the lower end of the outer peripheral wall and the lower end of the auxiliary wall, so that pain is caused. You can carry it with confidence without feeling. At this time, since there are a plurality of auxiliary walls provided on the inner portion of the outer peripheral wall, the load of the entire cooker applied to the fingers is distributed to the lower end of the outer peripheral wall and the lower ends of the plurality of auxiliary walls, and the auxiliary wall and the auxiliary Since the strength of the auxiliary wall can be improved by the reinforcing rib provided between the walls, a sense of stability is further increased, and the portable device can be carried with confidence. Further, since no reinforcing rib is formed between the auxiliary wall disposed inside the outer peripheral wall and the outer peripheral wall, the occurrence of sink marks due to the formation of the reinforcing rib can be avoided, and the appearance can be prevented from being affected.
