Description

  The present invention relates to a grill door that opens and closes a front opening of a grill cabinet provided on a stove with a grill.

 Conventionally, this type of grill door is known in which an upper edge member is provided along the upper edge of the door body (see Patent Document 1 below).

  The door body is made of a metal door frame that closes the grill cabinet, a window portion in which a glass plate is fitted so that the inside of the grill cabinet can be seen, and a gripping portion for the user to grip when opening and closing the grill cabinet. And.

  The upper edge member is made of synthetic resin or the like, and is provided to reduce discomfort due to heat when the user accidentally touches the upper edge of the grill door that has become hot. Also, a ventilation path for circulating cooling air is formed inside the door body, and a cooling air discharge hole communicating with the ventilation path inside the door body is provided in the upper edge member, thereby providing a ventilation path inside the door body. The upper edge member is also cooled by the air that has passed.

JP 2012-42106 A

  However, the cooling air that passes through the air passage inside the door body cools the door body prior to cooling the upper edge member. For this reason, the cooling air passing through the discharge hole of the upper edge member is already in a high temperature state, and the temperature of the upper edge member cannot be sufficiently lowered.

  In view of the above, it is an object of the present invention to provide a grill door that can reliably suppress an increase in the temperature of an upper edge member and can reduce discomfort due to heat when touched by a user.

In order to achieve such an object, the present invention is a grill door for opening and closing a front opening of a grill cabinet provided on a stove with a grill, and abuts against the opening edge of the grill cabinet to close the grill cabinet. a door body which, Bei example the upper edge member of oblong shape provided along the entire length of the upper portion of the door body, the upper edge member is at both ends in the longitudinal direction, connecting to connected and fixed to the door body The upper edge member is provided at a cover portion that covers the upper end portion of the door main body through a gas-permeable gap and at both ends in the longitudinal direction of the cover portion, and is connected to the door main body. A pair of connecting portions, and the door body includes an extending portion extending from a part of an upper end thereof toward the cover portion of the upper edge member, and the extending portion is connected to the connecting portion. one of the covering portion of the upper edge member to limit the bending deformation of the covering portion at different positions The Rukoto is an engagement shape to, the covering portion is characterized in that it comprises the abutting portion in a part of said cover portion when the curved deformation.

  The upper edge member prevents the user from directly touching the upper edge of the door body. Furthermore, the said cover part of an upper edge member has covered the upper end of the door main body through the space | gap which can ventilate. Thereby, the heat of a door main body becomes difficult to be directly transmitted to a cover part, and the temperature rise of an upper edge member can be suppressed.

  However, since the cover part of the upper edge member is provided in a long range along the upper edge of the door body between the connecting parts connected to the door body, a small amount of heat is transmitted from the door body. However, there is a risk that curved deformation such as warping may occur due to the use of the grill over a long period of time. And when such a curved deformation occurs in the upper edge member, not only is it not preferable in appearance, but the gap between the upper end of the door main body and the cover portion becomes narrow, and there is a possibility that the heat insulation effect due to the gap is reduced. .

  Therefore, in the present invention, the extension portion is provided at the upper end of the door body, and the bending deformation of the cover portion is limited by locking the extension portion to a part of the cover portion. Thereby, the temperature rise of an upper edge member can be suppressed reliably.

  As described above, according to the present invention, it is possible to reliably suppress an increase in the temperature of the upper edge member and to reduce discomfort due to heat when the user touches it.

  Further, in the present invention, the door body includes a metal door frame in which a window portion is formed and a glass plate attached to the front surface of the window portion, and the upper edge member is an upper portion of the door frame. The door frame covers the outer surface on the upper end side of the glass plate at a predetermined distance from the outer surface, thereby forming a gap between the outer surface on the upper end side of the glass plate and the door frame. It is characterized by including a gap forming portion.

  The glass plate attached to the window allows the inside of the grill to be visible, but heat is easily stored by using the grill. In the present invention, by providing the gap forming portion in the door frame, the gap between the outer surface on the upper end side of the glass plate and the door frame can be made into a heat insulating layer by air. According to this, transmission of heat from the door frame to the glass plate can be suppressed, and radiant heat from the glass plate can also be reduced. Therefore, the influence of the radiant heat from the glass plate on the upper edge member attached to the upper part of the door frame can be reduced, and the temperature rise of the upper edge member can be reliably suppressed.

  An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the grill door 1 of this embodiment is provided in the center part of the front side of the stove 2 with a grill, and the grill store | warehouse | chamber 3 (a part is shown in FIG. 3) provided in the inside of the stove 2 with a grill. Open and close the front of (shown).

  In the stove 2 with grill, a stove top plate 5 is provided on the top of the stove body 4, and the stove top plate 5 is provided with stove burners 6 and 7 exposed above. On both sides of the grill door 1 on the front side of the stove 2 with grill, there are operating knobs 8 and 9 for igniting, adjusting the thermal power and extinguishing the stove burners 6 and 7 and a grill burner (not shown) in the grill cabinet 3. An operation knob 10 is provided for performing ignition, thermal power adjustment, and fire extinguishing.

  As shown in FIGS. 2 and 3, the grill door 1 includes a door body 11 and an upper edge member 12. The door body 11 includes a door frame 13 made of a metal such as iron or stainless steel, a front panel 14 made of heat-resistant synthetic resin, and a rectangular glass plate 15.

  The door frame 13 is formed with a window portion 16 that allows the inside of the grill cabinet 3 to be visually recognized. A glass plate 15 is fitted and supported on the front surface of the door frame 13. The glass plate 15 covers the front surface of the window portion 16 in a state where the inside of the grill cabinet 3 is visible.

  An inner surface plate 17 is integrally provided below the window portion 16 of the door frame 13. The front panel 14 is positioned below the glass plate 15 and connected to the inner surface plate 17 of the door frame 13 by a plurality of screw members 18.

  As shown in FIGS. 1 and 3, a grip portion 19 is provided on the front side of the front panel 14, and the grill door 1 can be opened and closed by gripping the grip portion 19. Although not shown, the grill door 1 is connected to the front end of a support frame that supports the grill and the soup pan received in the grill cabinet 3. By opening and closing the grill door 1, the grill net and the juice tray are put in and out, and a cooked item such as fish is placed on the grill net.

  When pulling out the grill door 1 to take out grilled fish or the like from the grill cabinet 3, the user's hand or the like may accidentally touch the upper edge of the grill door 1. Therefore, in order to reduce discomfort due to heat when the user touches the upper edge of the grill door 1, an upper edge member 12 is provided over the entire upper edge of the door body 11.

  The upper edge member 12 is formed of a synthetic resin having heat resistance such as polyphenylene sulfide resin (PPS). As shown in FIGS. 2 and 4, the upper edge member 12 includes connecting portions 20 at both ends in the longitudinal direction, and is connected and fixed to both ends of the upper edge of the door frame 13 by screw members 21. The upper edge member 12 may be made of a material having high heat resistance, such as ceramic, in addition to the synthetic resin member.

  Between the connecting portions 20 of the upper edge member 12, a cover portion 22 that covers the upper end portion (upper end surface and upper front surface) of the door frame 13 via a ventilable gap is formed. A standing wall 23 is formed on the front edge of the cover 22.

  The air gap between the upper end portion of the door frame 13 and the cover portion 22 not only provides heat insulation by air, but also allows the cooling effect to be obtained by passing air between the door frame 13 and the cover portion 22. Furthermore, even when the user touches the upper edge member 12, the contact area when the upper edge of the upright wall 23 is touched is small, and the unpleasant feeling of heat when using the grill can be reduced.

  As shown in FIG. 3, the upper edge member 12 projects forward from the glass plate 15 that is the front surface of the door body 11. Thereby, the air which raises along the front surface of the glass plate 15 can be smoothly taken in into the space | gap between the door frame 13 and the cover part 22, and the cooling effect of the upper edge member 12 by an airflow improves.

  Moreover, the upper part of the window part 16 in the door frame 13 covers the outer surface on the upper end side of the glass plate 15 with a predetermined distance. Thus, a gap is formed between the outer surface on the upper end side of the glass plate 15 and the upper portion of the window portion 16 in the door frame 13 (gap forming portion 24). A relatively large heat insulating layer is formed by air. The distance between the upper portion of the window 16 in the door frame 13 and the outer surface on the upper end side of the glass plate 15 is equal to or greater than the thickness dimension of the glass plate 15 in the present embodiment, but is not limited thereto. It suffices if the air gap forming part 24 can be formed so that a sufficient air insulation layer can be obtained within a range in which the appearance of the main body 11 is maintained.

  The air insulation layer of the gap forming part 24 reduces heat transfer from the door frame 13 to the glass plate 15. For this reason, since the temperature rise of the upper end part of the glass plate 15 is suppressed and the radiant heat from the glass plate 15 becomes difficult to reach the upper edge member 12, the temperature rise of the upper edge member 12 at the time of grill use can be suppressed.

  As shown in FIGS. 3 and 5, an extended portion 25 extending toward the front above the glass plate 15 is formed at the upper end portion of the door frame 13 to which the upper edge member 12 is attached. The extending portion 25 is bent downward at a position ahead of the glass plate 15, and a claw piece 26 having a width in the left-right direction smaller than that of the extending portion 25 is formed at the front end of the extending portion 25.

  The cover portion 22 of the upper edge member 12 is integrally provided with a small protrusion 27 (corresponding to a part of the cover portion 22 that locks the extending portion 25 in the present invention) on the back surface thereof. The small protrusion 27 is formed with an insertion hole 28 for inserting and locking the claw piece 26 of the extending portion 25 of the door frame 13 from above. In the manufacturing process of the grill door 1, the operation of inserting the claw pieces 26 into the insertion holes 28 is performed in a previous process of connecting the connecting portion 20 to the door frame 13.

  In the present embodiment, the insertion holes 28 are formed in the small protrusions 27 provided on the back surface of the cover portion 22 so that the claw pieces 26 are locked. However, the back surface of the cover portion 22 is horizontally directed backward. When the protruding portion is formed, a hole such as the insertion hole 28 may be formed in the protruding portion to lock the claw piece 26.

  As shown in FIGS. 3 and 6, in a state where the claw piece 26 is inserted into the insertion hole 28, a very slight gap is formed between the inner surface of the insertion hole 28 and the claw piece 26. Thereby, the heat of the door frame 13 is suppressed from being transmitted to the upper edge member 12 as much as possible. When the cover portion 22 is curved and deformed by heat, the small protrusion 27 on the back surface of the cover portion 22 comes into contact with the extension portion 25 while the deformation amount is small, or the claw piece 26 is formed on the inner surface of the insertion hole 28. Or the like, and further deformation is limited.

  Specifically, when a curved deformation occurs so that the central portion of the cover portion 22 rises upward, the small protrusion 27 on the back surface of the cover portion 22 rises following this deformation. When it slightly rises, it is brought into contact with the leading edge that is wider than the claw piece 26 of the extending portion 25, and curving deformation such that the central portion of the cover portion 22 rises upward is suppressed. When a curved deformation occurs such that the central portion of the cover portion 22 is recessed rearward (door frame 13 side), the small protrusion 27 on the back surface of the cover portion 22 moves rearward following this deformation. Since the inner surface of the insertion hole 28 comes into contact with the claw piece 26 when the protrusion 27 is slightly moved, the bending deformation is suppressed so that the central portion of the cover portion 22 is recessed backward. As a result, it is possible to prevent a situation in which the curved portion is greatly deformed so that the central portion of the cover portion 22 is recessed backward, and the gap between the cover portion 22 and the door frame 13 can be prevented from becoming narrow.

  In the present embodiment, a very small gap is formed between the inner surface of the insertion hole 28 and the claw piece 26 in a state where the claw piece 26 is inserted into the insertion hole 28. The insertion hole 28 and the claw piece 26 may be formed in a shape in contact with each other. In this case, heat is transmitted from the claw piece 26 contacting the insertion hole 28 to the small protrusion 27 even if the cover 22 is not curvedly deformed, but the curved deformation due to the heat of the cover 22 is strongly suppressed. be able to.

  With the above configuration, in the grill door 1 of the present embodiment, a wide space is secured between the door frame 13 and the glass plate 15 of the door main body 11 and the cover portion 22 of the upper edge member 12, so that mutual contact portions are obtained. In addition to being extremely small, the gap is prevented from becoming narrow due to the deformation of the upper edge member 12. Thereby, the temperature rise of the upper edge member 12 can be suppressed reliably, and the discomfort due to the heat when the user touches the upper edge member 12 can be reduced.
