Description

The present invention relates to a cooking device in which an inner frame member is attached to a through hole formed in a top plate.

Conventionally, in a cooking device such as a stove, it is known that an operation knob for igniting and adjusting the thermal power is provided on the top plate. By providing the operation knob on the top plate, operability is improved, but on the other hand, it is necessary to form a through hole in the top plate for penetrating the operation shaft of the operation knob. Foreign matter may invade.

Therefore, in order to prevent foreign matter from entering through the through hole of the top plate, an inner frame member is attached to the through hole (see Patent Document 1 below). This inner frame member has a tubular portion that stands above the top plate at a position corresponding to the inner edge of the through hole, and a brim-shaped portion that projects outward from the lower end of the tubular portion and abuts on the upper surface of the top plate via packing. It has a department.

The tubular portion that stands above the top plate blocks spills and the like flowing on the top plate and prevents them from entering the through holes. Further, the packing between the brim-shaped portion and the upper surface of the top plate prevents intrusion of boiling spills or the like from between the brim-shaped portion and the upper surface of the top plate.

Japanese Unexamined Patent Publication No. 2012-87953 (Fig. 5)

However, according to the above-mentioned conventional inner frame member, there is a disadvantage that the brim-shaped portion is exposed on the top plate and becomes conspicuous, and the flat and smooth appearance of the top plate is deteriorated. Further, if an adhesive is filled between the flange-shaped portion and the upper surface of the top plate in order to fix the inner frame member to the top plate, excess adhesive protrudes from the periphery of the collar-shaped portion, which is not preferable in appearance. Further, even if the brim-shaped portion is in close contact with the upper surface of the top plate, a step is formed along the outer periphery of the brim-shaped portion. If there is such a step on the upper surface of the top plate, not only is dirt easily attached to the step portion, but there is also the inconvenience that it takes time and effort to remove the partial dirt on the step.

In view of the above points, it is an object of the present invention to provide a cooking apparatus that does not deteriorate the appearance of the top plate, reduces the adhesion of dirt, and is easy to clean.

In order to achieve such an object, the present invention heats a housing having an open upper surface, a top plate covering the upper surface of the housing, and an object to be heated on the top plate supported in the housing. A heating portion, a rotation operation shaft extending upward of the top plate via a through hole formed in the top plate for operating the heating portion, and an annular shape attached to the through hole via an adhesive. In the cooking apparatus including the inner frame member of the above, the inner frame member is connected to a tubular wall that covers the inner peripheral peripheral surface of the through hole from the inside over the entire circumference and the lower edge of the tubular wall. A flange-shaped portion extending along the lower surface of the plate is provided, and a first filling portion for filling an adhesive is formed between the collar-shaped portion and the lower surface of the top plate, and the tubular wall and the through hole are formed. A second filling portion to be filled with an adhesive is formed between the inner edge peripheral surface of the surface, and the boundary between the tubular wall and the flange-shaped portion is formed from the first filling portion to the second filling portion, or It is characterized in that a suppressing portion for suppressing the flow of the adhesive exceeding a predetermined amount from the second filling portion to the first filling portion is provided.

According to the present invention, the inner frame member is attached to the through hole of the top plate by adhering a collar-shaped portion connected to the lower edge of the tubular wall to the lower surface of the top plate. As a result, the brim-shaped portion is not exposed on the upper surface of the top plate as in the conventional case, and no step is generated on the upper surface of the top plate due to the brim-shaped portion. Therefore, it is possible to provide a cooking apparatus that does not deteriorate the appearance of the top plate, reduces the adhesion of dirt, and is easy to clean.

Then, not only the adhesive of the first filling portion between the collar-shaped portion and the lower surface of the top plate is filled, but also the second filling portion between the cylindrical wall and the inner edge peripheral surface of the through hole is adhered. By filling with the agent, the inner frame member can be adhered and fixed relatively firmly to the through hole of the top plate, and the inner frame member can be reliably prevented from being inadvertently removed during cleaning or the like. be able to.

Further, the inner frame member is provided with a restraining portion at the boundary between the cylindrical wall and the flange-shaped portion. The restraining portion is, for example, an adhesive that goes from the first filling portion to the second filling portion when the inner frame member is inserted into the through hole of the top plate after applying the adhesive to the lower surface of the top plate or the upper surface of the upper portion of the collar. Suppresses the flow exceeding a predetermined amount (appropriate amount according to the size of the second filling portion). As a result, the adhesive of the first filling portion does not excessively flow toward the second filling portion in excess of a predetermined amount, and the adhesive of the second filling portion flows from between the cylindrical wall and the through hole to the top plate. It is possible to prevent it from overflowing. Therefore, the excess adhesive is not exposed from the periphery of the tubular wall onto the top plate, and it is possible to prevent the appearance from being deteriorated by the excess adhesive.

Further, the restraining portion is, for example, a place where the adhesive goes from the second filling portion to the first filling portion when the inner frame member is inserted into the through hole of the top plate after applying the adhesive to the outer peripheral surface of the tubular wall. Suppress the flow exceeding the fixed amount. When the inner frame member is inserted into the through hole of the top plate after applying the adhesive to the outer peripheral surface of the tubular wall, excess adhesive is scraped off from the outer peripheral surface of the tubular wall by the lower end of the through hole of the top plate. In this way, it flows toward the first filling portion. At this time, if a large amount of adhesive is scraped off from the outer peripheral surface of the tubular wall, the amount of adhesive in the second filling portion becomes small, and there is a possibility that the space between the tubular wall and the through hole cannot be reliably closed. By suppressing the flow of the adhesive from the second filling portion to the first filling portion in excess of a predetermined amount, the suppressing portion can surely close the space between the cylindrical wall and the through hole.

Further, in the present invention, the collar-shaped portion of the inner frame member surrounds the annular sealing surface that faces the lower surface of the top plate and forms the first filling portion, and the outer periphery of the sealing surface. It is characterized by having a ridge that protrudes upward and abuts on the lower surface of the top plate.

The adhesive filled in the first filling portion by the sealing surface is regulated by the ridges in the outward flow of the sealing surface, flows in the circumferential direction of the sealing surface, and is made uniform in the first filling portion. As a result, the collar-shaped portion of the inner frame member can be reliably adhered to the lower surface of the top plate.

By the way, if the ridges regulate the flow of the adhesive to the outside, when the amount of the adhesive filled in the first filling portion exceeds the required amount, the excess adhesive in the first filling portion becomes the first. 2 There is a risk of flow toward the filling part. When a large amount of excess adhesive flows to the second filling portion, the adhesive of the second filling portion overflows on the top plate, which is not preferable in appearance.

Therefore, it is preferable that the collar-shaped portion of the inner frame member includes a discharge portion for discharging the adhesive exceeding a predetermined filling amount in the first filling portion to the outside of the collar-shaped portion. According to this, the excess adhesive in the first filling portion is discharged from the discharging portion without going to the second filling portion, and it is possible to prevent the adhesive from overflowing onto the top plate.

It is explanatory cross-sectional view which shows the process of mounting an inner frame member on a top plate, FIG. 4A shows before mounting, and FIG. 4B shows after mounting. The perspective view which shows the modification of the inner frame member.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a gas stove 1 which is an embodiment of the cooking apparatus of the present invention. The gas stove 1 of the present embodiment includes a top plate 2 made of heat-resistant tempered glass that covers the upper surface of a housing (not shown), a gas burner 3 (heating portion), and a knob member 4. In addition, a trivet 5 surrounding the gas burner 3 is placed on the top plate 2. Although not shown, a cooking container (heated object) such as a pot containing cooked food is placed on the trivet 5.

As shown in FIG. 2, the knob member 4 is attached to a rotation operation shaft 6 projecting upward from the top plate 2. The rotation operation shaft 6 is provided in a gas cock (not shown) below the top plate 2, and extends upward through a through hole 7 formed in the top plate 2. The gas cock is provided with an ignition switch, and by operating the rotation operation shaft 6, the gas burner 3 can be ignited and extinguished, and the amount of fuel supplied to the gas burner 3 can be adjusted.

A circular inner frame member 8 is inserted into the through hole 7 of the top plate 2. As shown in FIG. 3, the inner frame member 8 includes a cylindrical tubular wall 9 and an annular plate-shaped flange portion 10.

As shown in FIGS. 2 and 3, the cylindrical wall 9 has a shape that covers the inner peripheral peripheral surface of the through hole 7 from the inside over the entire circumference and extends upward of the top plate 2. The collar-shaped portion 10 is continuously and integrally provided on the lower edge of the tubular wall 9, and has a shape that extends along the lower surface of the top plate 2. At the boundary between the tubular wall 9 and the brim-shaped portion 10, a restraining portion 11 projecting outward is formed. As shown in FIG. 4A, the restraining portion 11 includes corner portions 11a and is formed in a stepped shape. Then, as shown in FIG. 4B, a part of the upper surface 11b from the corner portion 11a of the suppressing portion 11 faces the peripheral lower surface of the through hole 7 of the top plate 2.

Further, as shown in FIG. 3, the flange-shaped portion 10 includes a flat sealing surface 12 and a ridge 13 protruding so as to surround the outer periphery of the sealing surface 12. The ridge 13 protrudes to a size such that the top portion abuts on the lower surface of the top plate 2 (see FIG. 2). Further, a plurality of notches 14 (discharging portions) are formed in a part of the ridge 13.

As shown in FIG. 4B, the sealing surface 12 of the flange-shaped portion 10 and the lower surface of the top plate 2 form a first filling portion 16 which is a space for filling the adhesive 15. The tubular wall 9 and the peripheral surface of the inner edge of the through hole 7 form a second filling portion 17, which is a space for filling the adhesive 15. As the adhesive 15, an adhesive having heat resistance and sealing properties such as a silicone-based sealing material is adopted.

The inner frame member 8 having the above configuration is fixed to the top plate 2 as follows. That is, as shown in FIG. 4A, first, the adhesive 15 is applied around the through hole 7 on the lower surface of the top plate 2.

Next, as shown in FIG. 4B, the cylindrical wall 9 is inserted through the through hole 7, and the flange-shaped portion 10 is pressed against the lower surface of the top plate 2. The adhesive 15 penetrates between the cylindrical wall 9 that becomes the second filling portion 17 and the inner edge peripheral surface of the through hole 7 by receiving pressure contact between the lower surface of the top plate 2 and the sealing surface 12 in the first filling portion 16. ..

At this time, the adhesive 15 from the first filling portion 16 to the second filling portion 17 passes through the restraining portion 11 in which the distance between the inner frame member 8 and the top plate 2 is narrower than the other portions. , The flow is suppressed to exceed a predetermined amount. The restraining portion 11 has a shape that limits the passing amount of the adhesive 15 to a predetermined amount or less (an appropriate amount according to the size of the second filling portion 17). That is, a part of the upper surface 11b of the restraining portion 11 approaches (or comes into contact with) the lower surface of the top plate 2 to limit the amount of passage of the adhesive 15 to an appropriate amount.

As a result, the adhesive 15 is prevented from overflowing onto the top plate 2, and the second filling portion 17 is in a state where an appropriate amount of the adhesive 15 is filled.

Further, the adhesive 15 of the first filling portion 16 is restricted by the restraining portion 11 and at the same time restricted by the ridges 13, and spreads uniformly along the sealing surface 12. At this time, if the amount of the adhesive 15 in the first filling portion 16 is excessive, the excess adhesive 15 is discharged from the notch 14, and the adhesive 15 in the first filling portion 16 is adjusted to an appropriate amount. Will be done.

In this way, since the excess adhesive 15 of the first filling portion 16 is discharged by the notch 14, the excess adhesive 15 does not flow into the second filling portion 17, and the second filling portion 17 is adhered. The appropriate amount of agent 15 is maintained. Therefore, the adhesive 15 does not overflow on the top plate 2 and is not exposed, and the good appearance of the top plate 2 is maintained.

Further, as shown in FIG. 2, the flange-shaped portion 10 is adhered to the lower surface of the top plate 2 and is not exposed on the upper surface of the top plate 2, so that a refreshing impression can be given to the user. ..

Then, the inner frame member 8 is firmly adhered and fixed to the top plate 2 and securely attached to the through hole 7, and the cylindrical wall 9 extending upward from the through hole 7 causes spillage from the through hole 7 or the like. The flow can be reliably prevented.

In the present embodiment, the restraining portion 11 included in the inner frame member 8 has a shape in which the upper surface 11b projects toward the lower surface side of the top plate 2 and faces the lower surface side, as shown in FIG. 4B. The shape of the restraining portion is not limited to this, and any shape may be used as long as it can be limited to an appropriate amount when the adhesive 15 flowing from the first filling portion 16 to the second filling portion 17 passes through. For example, the restraining portion may be shaped so that the outer peripheral corner portion 11a faces the lower end corner portion of the through hole 7 of the top plate 2.

Further, in the present embodiment, as the discharge portion of the present invention, as shown in FIG. 3, notches 14 are provided in a part of the ridges 13 (4 locations in the present embodiment), but the first filling portion 16 When the filling amount of the adhesive 15 to the adhesive 15 is relatively small, as shown in FIG. 5, the ridges 13 may be provided so as to be continuous over the entire circumference of the flange-shaped portion 10, and the notch 14 may not be provided. .. Further, the discharge portion of the present invention is not limited to the notch 14, and for example, although not shown, a through hole may be provided in a part of the sealing surface 12 near the ridge 13 to serve as the discharge portion.

Further, in the present embodiment, as shown in FIGS. 4A and 4B, after applying the adhesive 15 around the through hole 7 on the lower surface of the top plate 2, the tubular wall 9 of the inner frame member 8 is formed through the through hole. Although the case of inserting through the inner frame member 8 has been described, in addition to this, after applying an adhesive to the outer periphery of the tubular wall 9 of the inner frame member 8, the tubular wall 9 of the inner frame member 8 is inserted into the through hole 7. It may be. In this case, the adhesive 15 of the second filling portion 17 flows toward the first filling portion 16, but the suppressing portion 11 limits the flow of the adhesive 15 so that the adhesive of the second filling portion 17 flows. It is possible to prevent an excessive outflow of 15. Therefore, it is possible to prevent the filling amount of the adhesive 15 into the second filling portion 17 from being too small.

Further, in the present embodiment, the gas stove 1 having the gas burner 3 as a heating unit is mentioned as a cooking device, but the cooking device of the present invention is not limited to this, and is suitably adopted for, for example, an IH stove or the like. Can be done.
