Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove having a stove body having at least one gas burner and a top plate having a flat portion covering an upper portion of the stove body.

[0002]

2. Description of the Related Art It is known that a conventional stove of this kind is provided with a cover so that the burner portion is not exposed to the outside when it is not used. For example, the actual development Sho 58-916
According to No. 06 and No. 61-138917,
It is known that a plate-like cover that covers the entire top plate of the stove is attached to the rear part of the stove body using a hinge so that the cover can be opened and closed. In the case of a stove equipped with such a conventional cover, the cover has a heavy weight, and in order to prevent the cover from rapidly closing due to its own weight, a biasing means such as a spring should be attached to the hinge part to bias the cover in the opening direction. This prevents the cover from closing rapidly and allows the cover to be opened and closed with a small force.

[0003]

In the conventional stove provided with the cover, since the cover is biased in the opening direction, the cover is slightly opened by the biasing force even when the cover is closed, and the space between the cover and the stove is increased. There is a gap in. If there is a gap between the cover and the stove with the cover closed,
Not only is it unfavorable in terms of design, but dust and insects may get into the cover through the gap.

In view of the above problems, it is an object of the present invention to provide a stove that can be opened and closed with a small force and has no gap between the cover and the stove.

[0005]

In order to solve the above problems, a stove according to the present invention has a stove body having at least one gas burner, and a top plate having a flat portion for covering the top of the stove body. In the above, a continuous convex portion surrounding one burner is formed on the top surface of the top plate, and a plate-like cover that fits within the range surrounded by the convex portions is detachably provided on the top plate.

The cover is made smaller and lighter by covering one stove with one cover instead of covering the whole stove with one cover as in the conventional stove. Also,
Since the cover is set so that it fits within the range surrounded by the convex portion, it is difficult to form a gap between the convex portion and the cover.

Further, when the positioning block is provided on the flat portion of the top plate within the range surrounded by the convex portions and the cover is attached, the cover is placed on the positioning block and the flat portion and the cover are attached. If you create a gap between them,
The flat portion and the cover do not come into close contact with each other, and a large force is not required particularly when removing the cover.

Further, when the Gotoku is placed on the flat portion within the range surrounded by the convex portions, the Gotoku may be positioned on the side surface of the positioning block.

Further, if the upper end of the convex portion and the upper surface of the cover are substantially level with the cover attached, there is little unevenness in the state with the cover attached, which is excellent in design. It becomes a thing.

By the way, when the burner is ignited with the cover, the cover becomes hot. In such a case, a sensor for detecting the state where the cover is attached may be provided, and an ignition inhibiting means for inhibiting ignition to the burner when the cover is attached may be provided.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, reference numeral 1 is a cooktop top plate to which a drop-in stove 2 according to the present invention is attached. The cooking table top plate 1 may be fixed to the kitchen, or may be a table whose legs are fixed and movable on the lower surface. This cooktop top plate 1 has a double structure in the present embodiment, and is composed of an upper first cooktop top plate and a lower second cooktop top plate. A controller 3 controls the operation of the drop-in stove 2. This figure shows a state in which the cover 6 is set on the drop-in stove 2.

Referring to FIG. 2, H is a mounting hole,
A circular mounting hole is formed on the first cooktop top plate 11,
A rectangular mounting hole is formed in the second cooktop top plate 12. The outer shape of the stove main body 4 is rectangular, and when the stove main body 4 is inserted into the mounting hole H from below, the stove main body 4 is inserted into the rectangular mounting hole formed in the second cooktop top plate, but the first cooktop top plate 11 The mounting holes opened in the 2nd cooktop top plate 1
Since it is formed to have a diameter slightly smaller than the circumscribing circle of the mounting hole formed in No. 2, the four corners of the stove body 4 interfere and the stove body 4 does not enter the mounting hole of the first cooktop top plate 11. Since the shape of the mounting holes of the first cooktop top plate 11 is different from the shape of the mounting holes of the second cooktop top plate, the second cooktop top plate projects into the mounting holes of the first cooktop top plate. The structure will be the same as that done. The mounting flange 41 is inserted into the mounting hole of the first cooktop top plate 11 from above so as to be placed on the upper surface Ha of the protruding portion. Then, the mounting flange 41 and the stove body 4 are fastened to each other with screws 42.

By the way, the stove body 4 is provided with a connector 43 for electrically connecting with the controller 3 and a plug 44 for supplying power. Reference numeral 45 is a gas supply port into which the gas supply pipe is screwed. The stove body 4 has a built-in internal flame type gas burner 46 in which flame holes are arranged inside the annular burner.

When the stove body 4 and the mounting flange 41 are screwed to each other as described above, the mounting flange 41 is engaged with and held by the upper surface Ha of the protruding portion. Then, the top plate 5 is set in that state. The top plate 5 is formed with a flange portion 51 that extends outward at the upper end. When the flange portion 51 is set from above into the mounting hole of the first cooking table top plate 11, the flange portion 51 is on the upper surface of the first cooking table top plate. Engaged and the top plate 5 is held by the top surface of the first countertop plate.

With reference to FIG. 3, the outer peripheral edge of the mounting flange 41 rises upward to form a cylindrical wall portion. On the other hand, a packing 51a made of silicone rubber is attached to the lower surface of the flange portion 51 of the top plate 5 in order to improve the adhesion with the upper surface of the first cooktop top plate. And top plate 5
Is set, the upper end 41a of the cylindrical wall portion strongly abuts on the packing 51a. When the tip 41a comes into contact with the packing 51a in this way, the hot air generated by the combustion of the burner is shut off and does not act on the cooking table top 1 along the lower surface of the top plate 5.

The top plate 5 is a metal fitting integrally formed with a flange portion 51, and the silicon caulking agent 5 is attached to the fitting.
And a glass plate 52 attached by 3. An appropriate positioning block 54 is attached to the upper surface of the glass plate 52. Although the number of positioning blocks is three in this embodiment,
The number may be appropriately determined. When the cover 6 is set, the cover 6 is placed on the positioning block 54, and the upper surface of the cover 6 and the uppermost position of the top plate 5 are substantially aligned with each other.
In the present embodiment, the flange portion 51 and the first cooktop top plate 1
The step difference with the upper surface of 1 could be 1.7 mm.

In FIG. 2, 7 is Gotoku, and when not cooking, this Gotoku 7 is not used and the cover 6 is set on the top plate 5 as shown in FIG. The cover sensor 8 is attached to the glass plate 52 of the top plate 5. With reference to FIG. 4, the cover sensor 8 is composed of a pin 81 which is biased upward and is held so as to be vertically movable, and a micro switch 82 which is turned on and off by the vertical movement of the pin 81.
The upper end of the pin 81 protrudes upward from the glass plate 52 of the top plate 5, and when the cover 6 is set, the pin 81 will cover the cover 6
The micro switch 82 is turned on by pressing the switch. Then, a microcomputer (not shown) built in the stove body 4 detects that the cover 6 is set, and prohibits ignition of the gas burner even if an ignition operation is performed by the controller 3.

In the case of cooking, a knob 61, which is provided at the center of the cover 6 so as to be retractable, is projected so that the cover 6 is covered with the top plate 5.
Remove from. Then, set Gotoku 7 in the center of the top plate 5. Referring to FIG. 5, Gotoku 7 is used when using a cooking utensil such as a pot or a kettle of a normal size. This Gotoku 7
Feet 71 made of a plurality of heat-resistant resins are attached to the lower surface of the glass plate 52, and the glass plate 52 of the top plate 5 is prevented from being damaged by the foot 71 coming into contact with the glass plate 52. Further, a funnel-shaped inclined portion 72 is provided at the center of the Gotoku 7 and is configured to guide the spilled substance to the center by the inclined portion 72 when spillage or the like occurs from the cooking utensil. Although not shown, the boiled spills and the like that have been guided are collected in a tray provided in the stove body 4 and are removed as necessary. Alternatively, a hole may be formed in the cover 6 without providing the knob 61, and a finger may be caught in the hole to remove the cover 6 from the top plate 5.

When the cover 6 is removed in this manner, the pin 81 of the cover sensor 8 rises and the micro switch 82 is turned off. Therefore, the microcomputer determines that the cover 6 has been removed, and the ignition operation from the controller 3 is performed. Then, the gas burner 46 is ignited.

By the way, when using a large pot or the like much larger than Gotoku 7, Gotoku 7 is not stable. In that case, the large Gotoku 9 is placed on the glass plate 52 of the top plate 5 for cooking. The large-sized Gotoku 9 is formed by welding a plurality of claws 91 to the inner circumference of the ring 92. At that time, the inner end surface of the positioning block 54 regulates the outer periphery of the ring 92, and the Gotoku 9 is positioned so as to be located at the center of the top plate. When all the cooking is completed, the Gotoku 7 and the large Gotoku 9 are removed and the cover 6 is set on the top plate 5. Even when using the large-sized Gotoku 9, the Gotoku 7 is cooked while being attached to the top plate.

In the above embodiment, the glass plate 5 of the top plate 5 is used.
Although 2 and the cover 6 are made of glass, ceramics, metals, or other appropriate materials can be used.
