[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stove having a stove body provided with at least one gas burner and a top plate provided with a flat portion covering an upper portion of the stove body.
[0002]
[Prior art]
In a conventional stove of this type, there is known a cover provided so that the burner portion is not exposed to the outside when not used. For example, Japanese Utility Model Publication No. 58-91606 and Japanese Utility Model Publication No. 61-138117 disclose a plate-like cover that covers the entire top plate of the stove using a hinge at the rear of the stove body so as to be freely opened and closed. It has been. In such a stove with a conventional cover, the weight of the cover is heavy, and a biasing means such as a spring is attached to the hinge portion to prevent the cover from closing rapidly due to its own weight, and the cover is biased 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]
[Problems to be solved by the invention]
In the stove provided with the above-described conventional cover, the cover is urged in the opening direction. Therefore, even when the cover is closed, the cover is slightly opened by the urging force, and a gap is generated between the cover and the stove. If a gap is generated between the cover and the stove with the cover closed as described above, not only is the design undesirable, but dust and insects may enter the cover through the gap.
[0004]
In view of the above problems, an object of the present invention is to provide a stove that can be opened and closed with a small force and that does not cause a gap between the cover and the stove.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, a stove according to the present invention is a stove having a stove body provided with at least one gas burner and a top plate provided with a flat portion covering the upper portion of the stove body. A continuous convex part surrounding the burner is formed, a plate-like cover that fits within the range surrounded by the convex part is detachably provided on the top plate, and the positioning block is within the range surrounded by the convex part. Provided on the flat part of the plate, when the cover is attached, the cover is placed on the positioning block so that a gap is formed between the flat part and the cover, and within the range surrounded by the convex part Then, when the virtues are placed on the flat portion, the virtues are positioned on the side surface of the positioning block .
[0006]
Instead of covering the entire stove with one cover as in the conventional stove, the cover is made smaller and lighter by covering one stove with one cover. Further, since the cover is set so as to be within the range surrounded by the convex portions, it is difficult to form a gap between the convex portions and the cover.
[0007]
In addition, 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 a gap is formed between the flat portion and the cover. If the cover is formed, the flat portion and the cover do not adhere to each other, and a large force is not required particularly when the cover is removed.
[0008]
In addition, when the five virtues are placed on the flat portion within the range surrounded by the convex portions, the five virtues may be positioned on the side surface of the positioning block.
[0009]
In addition, if the upper end of the convex part and the upper surface of the cover are almost the same height when the cover is attached, the flatness is reduced with the cover attached, and the design is excellent. .
[0010]
By the way, when the burner is ignited with the cover in place, 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 prohibiting means for prohibiting ignition of the burner may be provided when the cover is attached.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, reference numeral 1 denotes a cooking table 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 that can be moved by fixing legs on the lower surface. The cooking table top plate 1 has a double structure in the present embodiment, and is composed of an upper first cooking table top plate and a lower second cooking table top plate. A controller 3 controls the operation of the drop-in stove 2. This figure shows a state where the cover 6 is set on the drop-in stove 2.
[0012]
Referring to FIG. 2, H is a mounting hole, a circular mounting hole is formed in the first cooking table top plate 11, and a rectangular mounting hole is opened in the second cooking table top plate 12. . The outer shape of the stove body 4 is rectangular, and when the stove body 4 is inserted into the attachment hole H from below, it enters the rectangular attachment hole established in the second cooking table top plate. Since the mounting hole opened in the step is formed to be slightly smaller in diameter than the circumscribed circle of the mounting hole opened in the second cooking table top plate 12, the four corners of the stove body 4 interfere, and the stove body 4 becomes the first cooking table. It does not enter the mounting hole of the top plate 11. In addition, since the shape of the attachment hole of the 1st cooking table top plate 11 differs from the shape of the attachment hole of the 2nd cooking table top plate, the 2nd cooking table top plate protrudes in the attachment hole of the 1st cooking table top plate. It becomes the same structure as that. The mounting flange 41 is inserted into the mounting hole of the first cooking table 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 a screw 42.
[0013]
Incidentally, the stove body 4 is provided with a connector 43 and a power supply plug 44 for being electrically connected to the controller 3. 45 is a gas supply port into which the gas supply pipe is screwed. The stove body 4 incorporates an internal flame type gas burner 46 in which flame holes are arranged in parallel inside the annular burner.
[0014]
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. Next, the top plate 5 is set. The top plate 5 is formed with a flange portion 51 extending outward at the upper end. When the top plate 5 is set from above with respect to the mounting hole of the first cooking table top plate 11, the flange portion 51 is formed on the upper surface of the first cooking table top plate. The top plate 5 is engaged and held by the upper surface of the first cooking table top plate.
[0015]
Referring to FIG. 3, the outer peripheral edge of mounting flange 41 rises upward to form a cylindrical wall portion. On the other hand, a packing 51a made of silicon rubber is attached to the lower surface of the flange portion 51 of the top plate 5 in order to improve adhesion to the upper surface of the first cooking table top plate. When the top plate 5 is set, the upper end 41a of the cylindrical wall portion comes into strong contact with the packing 51a. When the tip 41a comes into contact with the packing 51a in this way, the hot air generated by the burner combustion is cut off and does not act on the cooking table top plate 1 along the lower surface of the top plate 5.
[0016]
The top plate 5 is composed of a metal fitting integrally formed with a flange portion 51 and a glass plate 52 attached to the fitting with a silicon caulking agent 53. An appropriate positioning block 54 is attached to the upper surface of the glass plate 52. In the present embodiment, the number of positioning blocks is three. However, the number may be an appropriate number. 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 position of the uppermost part of the top plate 5 substantially coincide. In this Embodiment, the level | step difference between the flange part 51 and the upper surface of the 1st cooking stand top plate 11 was able to be 1.7 mm.
[0017]
In FIG. 2, reference numeral 7 denotes virtues. When cooking is not performed, the virtues 7 are not used, and the cover 6 is set on the top 5 as shown in FIG. 1. A cover sensor 8 is attached to the glass plate 52 of the top plate 5. Referring to FIG. 4, this cover sensor 8 includes a pin 81 that is biased upward and is held so as to be movable up and down, and a micro switch 82 that 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. When the cover 6 is set, the pin 81 is pushed down by the cover 6 and the micro switch 82 is turned on. Then, a microcomputer (not shown) built in the stove body 4 detects that the cover 6 is set, and prohibits the gas burner from being ignited even if the controller 3 performs an ignition operation.
[0018]
When cooking, a knob 61 provided in the center of the cover 6 so as to be retractable is protruded, and the cover 6 is removed from the top plate 5. Then, Gotoku 7 is set in the center of the top board 5. Referring to FIG. 5, Gotoku 7 is used when using a cooking utensil such as a normal size pot or kettle. A foot 71 made of a plurality of heat-resistant resins is attached to the lower surface of the five virtues 7 so that the glass plate 52 of the top plate 5 comes into contact with the glass plate 52 so that the glass plate 52 is not damaged. In addition, a funnel-shaped inclined portion 72 is provided at the center of Gotoku 7 so that when the cooking utensils are spilled, the spilled portion 72 guides the boiling to the center. Although not shown in the figure, the guided spillage or the like is collected in a tray provided on the stove main body 4 and removed as necessary. Alternatively, a hole may be formed in the cover 6 without providing the knob 61, and the cover 6 may be detached from the top plate 5 by hooking a finger into the hole.
[0019]
When the cover 6 is removed in this way, the pin 81 of the cover sensor 8 is raised and the micro switch 82 is turned off, so that the microcomputer determines that the cover 6 has been removed and the controller 3 performs an ignition operation. The gas burner 46 is ignited.
[0020]
By the way, when using a large pan or the like much larger than Gotoku 7, Gotoku 7 is not stable. In that case, the large virtues 9 are placed on the glass plate 52 of the top plate 5 for cooking. The large virtues 9 are formed by welding a plurality of claws 91 to the inner periphery of the ring 92. At that time, the inner end face of the positioning block 54 regulates the outer periphery of the ring 92, and positioning is performed so that the virtues 9 are located at the center of the top plate. When all cooking is finished, the virtues 7 and the large virtues 9 are removed, and the cover 6 is set on the top board 5. In addition, even when using the large Gotoku 9, the Gotoku 7 is cooked while attached to the top plate.
[0021]
In the above embodiment, the glass plate 52 and the cover 6 of the top plate 5 are made of glass, but ceramic, metal, or other appropriate materials can be used.
