Description

  The present invention relates to a cooking device using a glass plate as a top plate (top plate).

  Conventionally, as this type of gas stove, for example, Patent Literature 1 discloses a gas stove in which an operation portion is provided on the front surface of a stove body to operate a gas burner. Since this gas stove has an operating part on the front, it is not affected by the heat from the gas burner, but in a so-called drop-in type gas stove where the stove body is embedded in the opening of the counter top, the operating part is the counter top. There is a problem that the operability is poor because it is located below.

Therefore, for example, Patent Literature 2 discloses a gas stove in which an operation unit is provided on the top plate of the gas stove. On the other hand, there is one that employs a glass plate as a top plate that covers the upper surface opening of the stove body. The glass top plate is awarded for its cleanliness and resistance to dirt.

It was. Here, for example, it is conceivable to fix the metal plate 19 to the back surface of the glass plate 12 with an adhesive, but the adhesiveness of the adhesive to the glass plate 12 is not so high, and there arises a problem that the fixing strength is lowered. . However, with the configuration of this example, even if an adhesive is used, the attachment destination is a metal, so that sufficient fixing strength is ensured, and the metal plate 19 can be fixed with high fixing strength. Further, if the peripheral edge of the metal plate 19 is sandwiched between the glass plate 12 and the horizontal plate portion 13 s of the frame body 13, the fixing strength is further increased.

According to this embodiment, the following effects can be obtained.
(1) Since the metal plate 19 covering the back surface of the glass plate 12 is fixed to the gas stove 1 by being supported by the horizontal plate portion 13 s of the frame body 13, it is not necessary to use an adhesive composition on the glass plate 12. The metal plate 19 can be fixed with high fixing strength. Further, if the glass plate 12 which is a relatively heavy member is used as a weight and the metal plate 19 is sandwiched between the glass plate 12 and the frame body 13, the metal plate 19 can be fixed with higher fixing strength. can do.

  (2) The gas-type gas stove 1 is easily heated around by the flames of the gas burners 5 and 6, but the metal plate 19 is disposed, so that the heat of the gas burners 5 and 6 can be hardly transmitted to the glass plate 12. .

  (3) Since the bent part 23 which protrudes from the upper surface of the glass plate 12 is formed at the hole edge of the burner hole part 20, even if the spilling occurs from the cooking pot, the bent part 23 is blocked. The spillage does not flow from the burner opening 14 into the main body case 2.

  (4) Although a shock is applied to the burner opening 14 when placing a pan or the like on the virtues 15, a protective ring 24 is attached to the burner opening 14, so even if an impact is applied when placing a pan or the like, the burner opening 14 14 is hardly scratched.

  (5) Since the ribs 22 are formed on the metal plate 19, the metal plate 19 can be provided with rigidity. Even if the metal plate 19 is thermally expanded, the rib 22 acts to change the entire area. Since it becomes difficult to produce, the area change (area expansion) by thermal expansion can be suppressed.

(6) Since the metal plate 19 is locked to the protective ring 24, the metal plate 19 is in a state of being vertically regulated by the protective ring 24, so that bending near the burner opening 14 is less likely to occur.
In addition, this embodiment is not limited to the above, You may change into the following aspects.

  As shown in FIG. 13, the folded portion 41 may be formed at the distal end of the folded portion 23 by folding the distal end of the folded portion 23 inward toward the center of the burner opening 14. In this case, there is no need for a sharp portion at the tip of the bent portion 23.

  -Fixing of the metal plate 19 is not limited to the structure which supports a periphery between the glass plate 12 and the frame 13. For example, as shown in FIG. 14, in the horizontal plate portion 13s of the frame body 13, a pair of groove portions 42 are provided on the side end surfaces 13u facing each other, and the edge of the metal plate 19 is fitted therein to fix the metal plate 19.

In this case, an operation shaft opening 44 for passing the operation shaft 43 a of the knob switch 43 is formed in the glass plate 12, and the operation shaft hole 45 is formed in the metal plate 19 in accordance with the operation shaft opening 44. Although it is provided, the bent portion 46 may be formed at the hole edge of the operation shaft hole. Therefore, the bent portion 46 acts as a blocking stopper so that the spilled portion does not enter the main body case 2 from the operation shaft opening 44. Further, a folded portion 47 may be provided at the upper end of the bent portion 46.

  The support between the glass plate 12 of the metal plate 19 and the frame body 13 may use a method of fixing the metal plate 19 to the horizontal plate portion 13s of the frame body 13 with a screw 48 as shown in FIG. .

  The metal plate 19 is not limited to be supported at its periphery, and it is sufficient that at least two opposing sides are supported. That is, the metal plate 19 may be supported by the horizontal plate portions 13s of the front frame piece 13a and the rear frame piece 13b as in the previous examples. In this case, it may be configured to be supported by a part of the two sides.

-The structure which only puts the metal plate 19 on the glass plate 12 of the metal plate 19 and the horizontal plate part 13s of the frame 13 may be sufficient.
The metal plate 19 is not limited to covering the entire back surface of the glass plate 12, and may be only a part if the components in the main body case 2 are hidden.

The frame body 13 is not necessarily provided with the support piece 13k, but may have a configuration in which the support plate 13k is not provided and the metal plate 19 is supported by the flush horizontal plate portion 13s.
As a method for suppressing heat conduction to the glass plate 12, for example, a plurality of vent holes 49 or side holes of the ribs 22 are formed in the metal plate 19 as shown by a two-dot chain line in FIG. The heat conduction to the glass plate 12 may be suppressed by generating an air flow (convection) between the metal plate 19 and the metal plate 19. Further, even if the metal plate 19 is heated by the heat from the gas burners 5 and 6 and the thermal expansion occurs, the ventilation hole acts to make it difficult for the entire area to change, so the area change due to thermal expansion (area expansion) Can be suppressed.

The gas burners 5 and 6 are not limited to the internal flame type, but may be an external flame type with the flame outlet facing outward.
-The number of gas burners 5 and 6 is not necessarily two, and may be other than this.
The optical sensor is not limited to an element that emits and receives infrared light, and may be an element that can project and receive visible light, for example. The detection means is not limited to the optical sensor, and for example, a capacitance switch that operates by changing the capacitance on the top plate may be used.

The metal plate 19 is not limited to a plated steel plate, and may be a material such as a stainless steel plate.
The heating cooker is not limited to a gas type, and may be an electromagnetic type that generates current by flowing an electric current through a coil to generate electromagnetic force, and heats the pot by heat generated by the electromagnetic force. The cooking device is not limited to a gas type or an electromagnetic type, and may be a chrome heater type cooking device.

Next, technical ideas that can be grasped from the above-described embodiment and other examples will be described below together with their effects.
(1) A heat insulating material (25a, 25b) is interposed between the glass plate and the protective ring. In this case, even if the protective ring becomes hot, it is difficult to transfer the heat to the glass plate.
