Description

  The present invention relates to a stove provided with five virtues for placing a cooking container such as a pan above the stove burner.

Gas stove tops are recently popular for their flat shape due to their ease of cleaning and aesthetics. Examples of such a flat top plate include a glass plate and a stainless steel plate (see, for example, Patent Document 1).
JP 2001-193946 A

However, because the top plate is loaded with virtues and cooking pots, when it is made flat so that it cannot be drawn, etc., a certain amount of thickness is required. There was a problem that a small hole could not be provided.
In recent years, gas stoves that have been made low in virtues and shortened the distance between the cooking pot and the stove burner to improve thermal efficiency have become mainstream, but in the vertical direction, as before. Providing protrusions and holes for rotation prevention and positioning also raises the problem that the height of the five virtues increases and the distance cannot be shortened.
An object of the present invention is to solve the above-mentioned problems and to prohibit the rotation of the virtues even in a stove provided with a flat top plate that cannot form a small hole for stopping the rotation of the virtues.

The stove according to claim 1 of the present invention for solving the above-mentioned problems is
Place the five virtue mounting rings around the burner opening where the stove burner provided on the top plate is installed, and place the five virtues consisting of multiple virtue claws and the five virtue rings supporting the five virtue claws In the positioning stove,
By forming a protrusion extending in the lateral direction from the outer peripheral end on the back surface of the Gotoku ring, forming a recess on the outer peripheral side surface of the Gotoku mounting ring, and engaging the protrusion with the recess, The gist is to prohibit the rotation of the five virtues.

The stove according to claim 1 of the present invention having the above-described configuration is provided with a rotation stop of the virtues by engaging a protrusion formed on the back surface of the virtuosity ring with a recess formed on the outer peripheral lateral surface of the virtuosity mounting ring. It can be performed. At this time, since the protrusion is formed by extending in the horizontal direction and the protrusion and the recess are engaged in the horizontal direction, the height of the virtues can be kept low, and the distance between the stove burner and the cooking pan is reduced. Thus, it is possible to improve the thermal efficiency.
In addition, if the protrusion and the recess are not firmly engaged, the virtues will float from the virtues mounting ring, which will also prevent misplacement of the virtues.

And positioning is performed.

As shown in FIG. 4, the five virtues 6 are the five virtue claws 30 on which the cooking pan is placed, and the annular virtues on which the five virtue claws 30 are placed and surround the main flame outlet 9 of the annular stove burner 4. It consists of a ring 31.
The five virtue claw portions 30 are integrally formed by an annular claw connecting ring 32 and five five virtue claws 33 standingly joined to the claw connecting ring 32. The virtuosity claw 33 is a sharp streamline, and the tip extends outward. Further, the lower end of the virtuosity claw 33 is formed with a two-step projection 34 and is inserted into and fixed to a through hole 35 formed in the claw coupling ring 32. A small protrusion 36 is formed at the forefront of the protrusion 34.

The Gotoku ring 31 is processed by press molding of a single ring plate, and the inner peripheral side is inclined downward toward the center of the ring, and the inside is dropped into a stepped shape to form a claw mounting portion 37. is doing. On the innermost side of the claw placement portion 37, when the virtuosity claw portion 30 is placed on the claw placement portion 37, a small protrusion 36 of the virtuosity claw 33 is fitted to position the virtuosity claw portion 30. Are provided in five locations.
On the outer peripheral side of the virtually ring 31, a flat portion 39 is formed extending substantially horizontally toward the outside.
As shown in FIG. 5, two hook pieces 40 are formed in each of the two positions at the opposite positions of the outer peripheral portion of the back surface of the virtually ring 31 in the inner lateral direction.

Then, the five virtues 6 are formed by placing the five virtue claw parts 30 on the claw placing part 37 of the five virtue ring 31. At this time, the most-advanced small protrusion 36 of the two-stage protrusion 34 formed at the lower end of the virtuosity claw 33 fits into the positioning groove 38 provided in the virtuosity ring 31, thereby positioning the virtuosity claw 30. At the same time, the rotation of the five virtue claw portion 30 is stopped.
Further, the virtues 6 are positioned on the top plate 2 so as to surround the periphery of the stove burner 4 by placing the virtuosity ring 31 on the boiling ring 15. At this time, the virtually ring 31 has the flat portion 39 placed on the highest portion of the boiled ring 15, that is, on the convex portion 21, and is supported at six points of the convex portion 21.
Further, the hook 40 on the back surface of the gorgeous ring 31 is placed so as to be at the same position as the hollow portion 22 of the boiling ring 15, and the two hook pieces 40 are fitted on both sides of the hollow portion 22 to hook the hook piece 40. Is engaged with the recess 22.

  As shown in FIG. 6, the juice receiving tray 5 is provided with a central opening 41 through which the annular mixture chamber 7 of the burner body 8 is inserted, and a juice receiving portion 42 for receiving the soup that overflows from the cooking pan is formed around it. Is done. The soup pan 5 is supported by the burner body 8 by placing the periphery of the central opening 41 on the flange 11 of the burner body 8. The central opening 41 is formed with a notch 43 for inserting the electrode 12 and the thermocouple 13.

As described above, according to the stove 1 of the present embodiment, the ring-shaped packing that prevents the intrusion of the broth into the burner opening 3 has a double structure of the upper packing 16 and the lower packing 17, and the top plate 2 Since the lower packing 17 in contact is made of a material having excellent sealing properties, it is possible to surely prevent the broth from entering the burner opening 3 from the surroundings. And since the upper packing 16 which contacts the gotoku ring 31 heated by being exposed to the flame of the stove burner 4 through the boiled ring 15 is made of a material having excellent heat resistance, the heat resistance of the entire ring-shaped packing is assured. Improves durability and improves durability. As a result, it is possible to reliably prevent the broth from entering the burner opening 3 over a long period of time. In addition, since the five virtue rings 31 and the boiled ring 15 are point contacts by the convex portions 21, heat transfer to the upper packing 16 is also suppressed, and the durability performance is further improved.
Further, the upper packing 16 and the lower packing 17 are formed by sandwiching a ring-shaped packing composed of two packings of the upper packing 16 and the lower packing 17 between the boiled ring 15 and the flat plate 19 and bending the holding piece 24 between them. It does not come apart and can be easily and reliably integrated.
And since the upper packing 16 and the lower packing 17 are inserted | pinched from the upper and lower sides, the adhesiveness of the lower packing 17 and the flat plate 19 increases, and the penetration | invasion of broth can be prevented more reliably.

In addition, since the Gotoku ring 31 is placed on the convex portion 21 of the boiled spill ring 15, the contact area between the Gotoku ring 31 and the boiled spilled ring 15 is reduced. That is, since the five virtue rings 31 and the boiled ring 15 are in point contact, a space for blocking heat around the convex portion 21 can be secured. For this reason, it is possible to suppress heat transfer from the Gotoku ring 31 to the boiled spilled ring 15, to prevent the heat of the flame of the stove burner 4 from diffusing through the Gotoku ring 31, and to improve thermal efficiency. . Furthermore, since the heat transfer to the flat plate 19 through the boiling ring 15 can be prevented, the top plate 2 can be used safely without being heated. In addition, in order to prevent heat transfer between the spilled ring 15 and the flat plate 19, instead of using any special separate member (for example, a heat-resistant sheet), the spilled ring 15 is convex by pressing. Since it is a simple structure which only provides 21, manufacturing cost can be suppressed and it can implement at low cost.
Moreover, since the convex part 21 for making the Gotoku ring 31 and the boiled spilled ring 15 to be in point contact is provided on the side of the boiled ring 15, the Gotoku ring 31 touched by human eyes is not uneven and has a design. good. Moreover, since the Gotoku ring 31 does not have irregularities, it can be formed in a flat shape, and boiled juice or the like is less likely to adhere, and cleaning is easy.

Further, by engaging the hook piece 40 formed on the back surface of the gorgeous ring 31 and the recess 22 formed on the lateral surface of the boiling ring 15, a flat that cannot be processed to stop the rotation of the virtually 6. Even on the top plate having the shape, it is possible to prevent the rotation of Gotoku 6 well. Moreover, since the hook piece 40 is formed to extend in the horizontal direction and the hook piece 40 and the recess 22 are engaged in the horizontal direction, the height of the five virtues 6 can be kept low, and the stove burner 4 It is possible to improve the thermal efficiency by reducing the distance from the cooking pot.
Furthermore, if the hook piece 40 and the recess 22 are not firmly engaged, the virtues 6 are lifted from the spilled ring 15, so that the misplacement of the virtues 6 can be prevented.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
For example, in this embodiment, the five virtues 6 can be divided into the five virtue claw portions 30 and the five virtue rings 31, but the five virtue claws 33 may be directly erected and joined to the five virtue rings 31 to integrally form the five virtues 6. .
