Description

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

  A front opening of a grill cabinet such as a gas stove is opened and closed by a grill door. The grill door is configured by inserting a glass plate into a window opening formed in a metal door frame. Here, as the grill door, the lower end of the grill door is fixed to the front end of the grill pan that is freely retractable into the grill cabinet, and the grill pan is pulled out from the grill pan by pulling the grill door forward. To do.

  In such a grill warehouse, when the cooked food such as grilled fish is taken out from the grill warehouse, the grill door and the grill pan are pulled forward. At this time, the upper end of the door frame is exposed and the user's hand is It is easy to touch. The door frame is heated by radiant heat and conduction heat from the heat source in the grill cabinet, so if the user accidentally touches the upper end of the door frame, it will become hot and may cause discomfort to the user. .

  In this type of grill door, a heat insulating material made of silicon rubber is provided at the upper end of the door frame (see, for example, Patent Document 1).

JP 2003-93242 A

  With what is shown by patent document 1, although the heat when a user touches the upper end part of a door frame can be eased, the heat insulating material made from silicon rubber is soft, and cooking to a grill warehouse Since it is easy to come off when the user's hand touches it when putting in and out things, it is not easy to use.

  Further, it is conceivable that the upper edge of the door frame is covered with an upper edge member formed of a hard synthetic resin, and the upper edge member is securely fixed to the door frame with a screw member or the like to prevent inadvertent detachment. Even if the upper edge member is made of a hard synthetic resin, the heat felt by the user when the user accidentally touches the upper end of the door frame is not sufficiently reduced.

  The present invention was invented in view of the above-described conventional problems, and the object of the present invention is to provide a grill door that can sufficiently reduce the heat felt by the user even when the user touches the upper end of the door. The issue is to provide.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to a grill cabinet in which a grill cabinet is housed in a device main body, and a space for heat insulation is provided between the outer upper surface of the grill cabinet and the device main body. A grill door that opens and closes a front opening, wherein the grill door is in contact with a peripheral edge of the front opening of the grill cabinet and closes the front opening, and rearward from the upper end of the door main body. A closed position in which the grille door closes the front opening, and a heat insulating member that covers the upper surface of the flange while maintaining a gap between the flange extending toward the upper surface and the upper surface of the flange The flange portion and the heat insulating member are immersed in the heat insulating gap when positioned at the position.

  Since the heat insulating member is provided with a gap between the upper surface of the heel portion, heat conduction from the heel portion is suppressed, and the temperature of the heat insulating member is hardly increased, and cooking is performed in the grill cabinet. When the grill door is located at the closed position where the front opening is closed, both the flange portion and the heat insulating member are immersed in the heat insulation gap provided between the outer shell upper surface of the grill cabinet and the device main body. The temperature rise is further suppressed.

  In other words, the temperature of the heat insulation gap provided between the outer surface of the outer wall of the grill cabinet and the main body of the device is lower than that in the grill cabinet, and the temperature of the heel part that is immersed in the gap for heat insulation increases. It is suppressed. In addition, when cooking is performed in the grill cabinet, when the grill door is slightly opened from the closed position where the front opening is closed, a small amount of hot air overflows from the grill door periphery to the outside of the grill cabinet. Although the temperature near the upper end of the grill door rises due to the hot air that flows, the overflow of the hot air from the vicinity of the upper end of the grill door is suppressed by immersing both the flange portion and the heat insulating member in the gap for heat insulation. The temperature rise near the upper end of the door is further suppressed.

  The invention according to claim 2 is the invention according to claim 1, wherein the protrusions extending in the front-rear direction at the left and right ends of the upper surface of the heat insulating member are provided so as to protrude upward from the upper surface of the heat insulating member. It is characterized by.

  Thus, even when the grill door is slightly shifted upward when the grill door is in the closed position, the protrusion protruding upward from the upper surface of the heat insulating member acts as a spacer, and the device main body A gap can be ensured between the upper surface of the heat insulating member and the temperature rise of the heat insulating member is further suppressed.

  That is, although there is a gap for heat insulation between the outer shell upper surface of the grill cabinet and the device main body, the temperature of the device main body facing the outer shell upper surface of the grill cabinet increases as the temperature of the outer shell upper surface of the grill cabinet increases. Is. Then, when the temperature of the device main body facing the outer upper surface of the grill is increased, the protrusion acts as a spacer so that the upper surface of the heat insulating member does not directly contact the device main body and the temperature of the heat insulating member increases. Is further suppressed. Moreover, since the protrusions extending in the front-rear direction are provided at the left and right ends of the upper surface of the heat insulating member, the user extends in the front-rear direction when taking out the food to be cooked from the grill net to be provided at the rear part of the grill door. There is little risk of touching the ridges.

  Furthermore, since the protrusions acting as spacers extend in the front-rear direction on the upper surface of the heat insulating member, the grill door can be easily opened and closed even if this protrusion contacts the device body.

  The invention according to claim 3 is characterized in that, in the invention according to claim 1 or claim 2, a front end edge ridge projects from the front end edge of the heat insulating member upward. .

  Thus, when a clearance is secured between the equipment body and the top surface of the heat insulating member in order to prevent the top surface of the heat insulating member from coming into direct contact with the equipment body, it is formed between the upper end of the grill door and the equipment body. The belt-like gaps can be filled or covered with the front edge ridges, and a good aesthetic appearance can be obtained.

  Since the heat insulating member is provided with a gap between the upper surface of the flange portion, heat is not easily transmitted from the flange portion, the temperature of the heat insulating member is not easily increased, and the grill is in a state where cooking is performed in the grill cabinet. When the door is located at the closed position where the front opening is closed, both the flange and the heat insulating member are immersed in the heat insulating gap provided between the outer shell upper surface of the grill cabinet and the main body of the device. The rise is further suppressed.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In the embodiment shown below, the grill is a grill provided in the gas drop-in stove 1 with a grill shown in FIG. 1, but it may be a single grill without a stove, or at least a cooking device equipped with a grill. There is no particular limitation.

  The gas drop-in stove with a grill 1 includes a device body 11 that has front, back, left, and right side surfaces and opens upward, and a top plate 12 that closes the opening upward toward the rear of the device body 11. Near the front of the main body 11, the device main body 11 does not open upward, and the upper portion is covered by the front top surface 15 of the device main body. The top plate 12 is made of glass in the present embodiment, but is not particularly limited. The top plate 12 is provided with a plurality of stove portions having a stove burner 13.

  In the gas drop-in stove 1 with a grill, a grill cabinet having a grill burner (not shown) as a heat source is provided. The grill warehouse is composed of a housing that opens forward, and in this embodiment, the forward opening is connected to an opening of substantially the same shape that is formed in a substantially central portion of the front surface of the device main body 11 in the left-right direction. Thus, the front opening 10 communicates with the front of the gas drop-in stove 1 with a grill. The front opening 10 is closed by the grill door 2 so as to be opened and closed. The grill door 2 will be described later. Although not shown, a grill pan is provided at the rear of the lower part of the grill cabinet, and a grill net is placed on the grill pan to place the cooked food. It is configured to be heated. An exhaust passage for exhausting the combustion exhaust gas of the grill burner to the outside of the grill warehouse is continuously provided on the rear side of the grill warehouse so as to extend upward, and the combustion exhaust gas of the grill burner is passed to the rear portion of the top plate 12 through the exhaust passage. It is configured to lead to the formed exhaust outlet 14. The grill burner includes an upper burner that heats the upper surface of the food to be placed on the grill and placed on the grill, and a pair of left and right lower burners that heat the lower surface of the food to be placed on the bottom of the grill. The upper and lower burners and one of the upper and lower burners may be used, and are not particularly limited. In addition to the grill burner, the heat source may be one that does not rely on combustion, such as a heater that radiates radiant heat when energized.

  On both sides of the grill door 2 on the front surface of the apparatus main body 11, a stove burner 13 and a grill burner operation section 7 are provided.

  Hereinafter, the grill door 2 will be described with reference to FIGS. 2 to 7. The grill door 2 has a metallic door main body 21, a metal flange 22 extending rearward from the upper end of the door main body 21, and a gap 24 between the upper surface of the flange 22. The main body is composed of a heat insulating member 23 made of resin that covers the upper surface of the portion 22. The heat insulating member 23 is fixed to the upper end portion of the door body 21 together with the flange portion 22 by screws. Moreover, the material of the door main body 21, the collar part 22, and the heat insulation member 23 shows an example used by the present Example, and the structure of this invention is not limited to the said material.

  At both the left and right ends of the upper surface of the heat insulating member 23, a protrusion 25 extending in the front-rear direction is provided to protrude upward, and a front end edge protrusion 3 is provided to protrude upward from the front end edge of the heat insulating member 23.

  As shown in FIGS. 4 to 6, a metal collar 22 is extended to the upper end of the door body 21 by screwing toward the rear, and a gap 24 is maintained between the upper surface of the collar 22. When the heat insulating member 23 is screwed together with the flange portion 22 and the door body 21 comes into contact with the peripheral edge 4 of the front opening 10 of the grill cabinet, both the flange portion 22 and the heat insulating member 23 are the outer upper surface 31 of the grill cabinet. And a space 16 for heat insulation formed between the front surface 15 and the front top 15 of the apparatus body.

  The heat-insulating gap 16 suppresses the temperature rise of the apparatus main body front top surface 15 due to the heat of the outer upper surface 31 of the grill cabinet, which becomes high when the grill is used. No. 16 has a temperature lower than that in the grill.

  When the grill is used, the temperature of the door main body 21 rises due to a rise in the temperature in the grill cabinet. When the cooking on the grill is completed, the user takes out the fish to be cooked. Since the rear side of the upper end of the grill door 2 that is likely to be touched by mistake is covered with a heat insulating member 23 made of resin with a gap 24 between the upper surface of the flange portion 22, Heat that is difficult for the heat to be transmitted to the rear side of the upper end of the grill door 2, that is, the rear side of the heat insulating member 23, is felt by the user.

  When the grill is used, the door main body 21 does not come into contact with the peripheral edge 4 of the front opening 10 of the grill cabinet, and there is a slight gap 41 between the door main body 21 and the peripheral edge 4 of the front opening 10 of the grill storage. In this case, the hot air in the grill is leaked from the gap 41. However, since the flange 22 and the heat insulating member 23 are both immersed in the gap 16 for heat insulation, the hot air overflowing from the gap 41 is After flowing below the flange portion 22, it once flows to the rear side of the heat insulation gap 16, and then wraps around from the rear side of the heat insulating member 23 to the upper surface side of the heat insulating member 23, and is then discharged to the front of the gas drop-in stove 1 with a grill. The

  On the other hand, when the grill 22 is not provided with the flange portion 22 and the heat insulation member 23 that are immersed in the heat insulation gap 16, the door body 21 contacts the peripheral edge 4 of the front opening 10 of the grill cabinet. If there is a slight gap 41 between the door body 21 and the peripheral edge 4 of the front opening 10 of the grill cabinet, the hot air overflowing from the gap 41 once passes below the flange portion 22 as described above. Since there is no increase in the passage resistance of the overflowing hot air that flows to the rear side of the heat insulation gap 16 and then wraps around from the rear side of the heat insulation member 23 to the upper surface side of the heat insulation member 23, the heat insulation gap 16 The amount of overflowing hot air is increased as compared with the case where the immersive flange 22 and the heat insulating member 23 are provided, and the temperature at the upper end of the grill door 2 is increased.

  That is, when the flange 22 and the heat insulating member 23 are inserted into the heat insulating gap 16, the grill door 2 is compared with the case where the flange 22 and the heat insulating member 23 are not provided. The temperature at the top is reduced.

  The hot air overflowing from the gap 41 between the front opening 10 of the grill warehouse first hits the flange 22 and then flows below the flange 22 to the rear side of the heat insulation gap 16 once. Since the hot air overflowing in between is lowered in temperature and then circulates to the upper surface side of the heat insulating member 23, there is no problem with respect to heat resistance even if the heat insulating member 23 is generally made of a material such as a resin having a low heat resistant temperature.

  Furthermore, generally, the heat source for the grill is provided on the rear side of the peripheral edge 4 of the front opening 10 of the grill warehouse, and the outer upper surface 31 of the grill warehouse on the rear side of the peripheral edge 4 of the front opening 10 of the grill warehouse. The heat propagated from the top surface of the device main body to the top surface of the device main body 15 due to heat conduction increases the temperature of the top surface 15 of the device main body. The protrusion 25 extending in the front-rear direction is a spacer even when the grill door is slightly displaced upward when the grill door is in the closed position due to manufacturing variations or the like. As a result, it is avoided that the upper surface of the heat insulating member 23 near the center in the left-right direction is in direct contact with the top front surface 15 of the apparatus main body, and the temperature rise near the center of the heat insulating member 23 in the left-right direction is further suppressed.

A front edge ridge 3 is projected from the front edge of the heat insulating member 23 upward. When a clearance is secured between the front surface 15 of the front of the apparatus body and the upper surface of the heat insulation member 23 in order to avoid the upper surface of the heat insulation member 23 from directly contacting the top surface 15 of the apparatus body, the grill door 2 Can be filled or covered with the front edge ridge 3 to reduce the temperature of the upper end of the grill door 2 and have a good aesthetic appearance as described above. can get.
