Abstract

PROBLEM TO BE SOLVED: To improve the fitting property and assembly property of a seal packing, and to improve the adhesion sealing performance with a counter top. SOLUTION: The inside and the surrounding of a seal packing 14 are covered with sponge rubber 12 and solid rubber 13, respectively, thus making soft the inside of the seal packing 14, allowing the surrounding to have a sealing property, enabling the seal packing 14 to be inserted easily regardless of the scattering of the shape dimensions of the surrounding of the top plate, and hence improving assembly working efficiency. Also, the area to a kitchen counter 1 can be constantly glued and sealed against the warpage of the surrounding of the top plate.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal packing for a top plate of a cooking appliance.

[0002]

2. Description of the Related Art FIG. 3 is a plan view of a conventional built-in type cooking device, in which a stove burner 2 is disposed on an upper surface of a kitchen counter 1, and a top having four corner portions 3 and four straight portions 4 is provided. A plate 5 is placed, and a seal packing 6 made of silicone rubber is provided on the outer periphery of the top plate 5. FIG. 4 is a main cross-sectional view of FIG. 3 and shows a main part of a mounting portion of the top plate 5 and the seal packing 6. A vertical piece 7 around the top plate 5 is bent inward to form a hook shape. Then, the insertion piece 8 of the seal packing 6 is press-fitted and held in the hook-shaped space of the top plate 5, and the bottom surface 9 is attached to the opening 1 of the kitchen counter 1.
0 is mounted on the outer peripheral upper surface.

[0003] Reference numeral 10 denotes a hollow portion provided at the center of the cross section of the insertion piece 8, which facilitates insertion of the seal packing 6 into a hook-shaped space of the top plate 5. Further, the bottom portion 8 tightly seals the gap between the top plate 5 and the kitchen counter 1 to prevent spills during heating and water during cleaning from entering the opening 10 of the kitchen counter 1. I have.

[0004]

This type of built-in cooker is frequently used daily, and it is required that the cooker has good spillage and cleanability during heating cooking. Although the vertical piece 7 around the top plate 5 is bent inward to form a hook shape, the entire outer circumference of the top plate 5 is long and the bending is not stable, so that the hook at the corner portion 3 and the straight portion 4 is not formed. There was a variation in the shape, and in the corner portion 3, the insertion portion was wide and the fitting and holding with the seal packing 6 could be loosened in some cases. In addition, straight part 4
In this case, the insertion portion is narrow, so that it is difficult to insert the insertion piece 8 of the seal packing 6, or the insertion portion is wide, and there are places where the fitting is loose. Further, the warp around the top plate 5 and the combustion of the stove burner 2 increase the warp of the top plate 5 to form a gap between the seal packing 6 and the kitchen counter 1. Had the problem of flowing into

[0005]

According to the present invention, in order to solve the above-mentioned problems, the inside of a seal packing is formed by covering with sponge rubber and the periphery thereof is coated with solid rubber.

According to the present invention, the seal packing can be easily inserted into the top plate, and the seal packing can be tightly sealed with the kitchen counter without coming off.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a top plate is arranged around the upper surface of a kitchen counter opening, a seal packing is provided on the outer periphery of the top plate, the inside of the seal packing is made of sponge rubber, and the periphery is solid rubber. This makes it easy to assemble the top plate and the seal gasket, prevents the seal gasket from coming off during cleaning, and makes it possible to always tightly seal with the kitchen counter.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in the conventional example shown in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof will be omitted.

(Embodiment 1) FIG. 1 is a sectional view of a top plate and a seal packing portion in which a top plate according to Embodiment 1 of the present invention is placed on a kitchen counter. In FIG. 1, a top plate 5 having a hook-shaped cross section is placed on an upper surface of an opening 10 of a kitchen counter 1 by bending a surrounding vertical piece 7 inward.

A sponge rubber 12 is interposed between the top plate 5 and the kitchen counter 1 and a seal packing 14 formed by covering the periphery with a solid rubber 13 is interposed between the top plate 5 and the kitchen counter 1. Seal tightly. The seal packing 14 has a hollow hole 15 in the center of the cross section, and is composed of an insertion piece 16 and a bottom face 17 located on the lower surface of the top plate 5. The formed insertion piece 16 is attached to the vertical piece 7 of the top plate 5. It is inserted into the hook-shaped inner space bent inward while receiving compression, and is attached to the top plate 5.

FIG. 2 is a detailed view of the seal packing 14 of FIG. Next, the operation will be described. The seal packing 14 has a sponge rubber 12 inside and a solid rubber 13
The inside is soft and has excellent cushioning properties, and the surrounding area is covered with the solid rubber 13 so that the inside is not broken and has excellent sealing properties. Seal packing 14
Is inserted into the hook-shaped inner space of the top plate 5 by being compressed. However, since the inside is formed of the sponge rubber 12, it is soft, rich in compression, easy to insert, and resilient. The seal packing 14 is firmly held on the top plate 5 by force and adheres to the inside of the top plate 5.

Further, in the hook shape in which the vertical piece 7 of the top plate is bent inward, the sponge rubber 12 inside the seal packing 14 is soft even if the shape of the corner portion 3 and the straight portion 4 is varied.
Can be easily inserted even if the insertion portion is narrow, the assembling property can be improved, and the seal packing 14 can be prevented from coming off.

On the other hand, the bottom portion 17 located on the lower surface also has a soft top surface 5 because the sponge rubber 12 is soft.
Is compressed only by the load of, and adheres tightly to the kitchen counter 1. Even if the top plate 5 warps, the elastic force of the sponge rubber 12 always adheres to the kitchen counter 1. In addition, since the periphery is covered with the solid rubber 13, the sealing performance against boiling over can be ensured.

[0014]

As described above, according to the present invention, since the inside of the seal packing is formed by covering with sponge rubber and the surroundings with solid rubber, the inside is soft and the surroundings have sealing properties. The seal packing can be easily inserted into the top plate even with respect to the variation in the shape and dimensions around the plate, so that the assembling workability can be improved and separation can be prevented.

[0015] Also, against the warpage around the top plate, the inside of the seal packing is rich in elasticity with sponge rubber, and the periphery is covered with solid rubber, so that it can be tightly sealed with the kitchen counter. .
