Description

  The present invention relates to a grill door that opens and closes a grill of a stove with a grill.

  As this kind of grill door, a metal door frame that closes the grill cabinet is provided, and a window portion into which a glass plate is fitted is formed on the door frame so that the inside of the grill cabinet can be seen, and the lower position of the window portion There is known one provided with a grip portion made of synthetic resin (for example, see Patent Document 1). When opening and closing the grill door, an opening / closing operation is performed by holding the grip portion.

  By the way, when the grill door is opened to open the grill cabinet, the upper edge of the door frame is exposed, so the user's hand touches the upper edge of the door frame when taking out grilled fish or other food from the grill cabinet. Cheap. And since a door frame becomes hot by the radiant heat from the heat source in a grill warehouse, when a user touches the upper edge of a door frame accidentally, he may feel heat and may give a user discomfort. .

  On the other hand, there is a grill door of this type in which a heat insulating material made of silicon rubber is provided on the upper edge of the door frame (see, for example, Patent Document 2). According to this, the heat when the user touches the upper edge of the door frame can be reduced, but the heat insulating material made of silicon rubber is soft and used when putting food in and out of the grill. Because it is easy to come off when a person's hand touches it, it is not convenient.

  In view of this, it is conceivable that the upper edge member formed of a hard synthetic resin covers the upper edge of the door frame, and the upper edge member is securely fixed to the door frame with a screw member or the like to prevent inadvertent detachment.

However, as described above, the metal door frame is heated by the radiant heat from the heat source in the grill cabinet. However, the upper edge of the door frame is in the length direction of the upper edge (left and right as viewed from the front of the grill). ) In the central portion is particularly hotter than the left and right sides, and the temperature distribution in the length direction of the upper edge becomes non-uniform. And, when the upper edge member made of hard synthetic resin is provided on the upper edge of the door frame with non-uniform temperature distribution in this way, it is synthesized from the difference in expansion coefficient due to heat between the door frame and the upper edge member. There is a possibility that the upper edge member made of resin may be deformed. That is, when both ends in the length direction of the upper edge member are fixed to the door frame by a pair of screw members, the central portion that is hottest is located between the screw members, so the central portion of the upper edge member is the door. Deforms to lift from the frame. For this reason, not only the appearance of the grill door is lowered, but also the durability of the upper edge member is lowered.
JP 2004-173780 A (FIG. 2) Japanese Patent Laying-Open No. 2003-93242 (FIG. 2)

  In view of the above points, the present invention provides an upper edge member made of hard synthetic resin that reduces discomfort caused by heat when a user's hand touches the upper edge of a metal door frame. It is an object of the present invention to provide a grill door that can be provided without deterioration of the property.

  In order to solve this problem, according to the present invention, in a grill door that opens and closes a front opening of a grill cabinet provided on a stove with a grill, a window portion that allows the inside of the grill cabinet to be visually recognized from the outside is formed. And a metal door frame that contacts the opening edge of the grill cabinet and closes the grill cabinet, and is fixed along the upper edge of the door frame that is not in contact with the opening edge of the grill cabinet. It is provided between the upper edge member made of hard synthetic resin and the upper edge member and the door frame over the entire length of the upper edge member. And a heat diffusion member made of a highly conductive material.

  According to the present invention, by providing the upper edge member along the upper edge of the door frame, even if the metal door frame is heated by the radiant heat from the heat source in the grill cabinet, the user's hand is directly An unpleasant feeling due to heat when the user touches the upper edge member can be reduced by the upper edge member made of a synthetic resin which prevents the door frame from being touched and has a lower thermal conductivity than metal. Further, in the state where the opening of the grill cabinet is closed by the door frame, the upper edge member is not in contact with the opening edge of the grill cabinet, so that heat is transferred from the opening edge of the grill cabinet to the upper edge member. Is suppressed. And by making the upper edge member made of a hard synthetic resin, the upper edge member can be firmly attached to the door frame using, for example, a screw member or the like, and inadvertent detachment due to user contact is prevented. At the same time, it is possible to reliably prevent the user from contacting the upper edge of the door frame from which the upper edge member is removed.

  Further, a heat diffusion member made of a material having higher thermal conductivity than the door frame is interposed between the door frame and the upper edge member. According to this, the heat which goes to a top edge member from a door frame can be spread | diffused, and the deformation | transformation by the heat of a top edge member can be suppressed. That is, since the door frame is made of metal and the upper edge member is made of synthetic resin, the thermal expansion coefficient differs between the door frame and the upper edge member. When the metal door frame receives radiant heat from the heat source in the grill cabinet, the central portion of the upper edge in the length direction is particularly hot at the upper edge of the door frame as compared to the left and right sides. Distribution becomes uneven. At this time, the heat transmitted from the door frame is dispersed right and left because the heat diffusion member has higher thermal conductivity than the door frame. Thereby, the heat transmitted from the door frame to the upper edge member is made uniform in the length direction of the upper edge member, and the transmitted heat is reduced, so that the deformation of the upper edge member due to the heat is extremely reduced. Therefore, according to the present invention, it is possible to obtain a heat diffusion effect by the heat diffusion member, suppress deformation of the upper edge member, and prevent deterioration of the appearance and durability of the grill door.

  Further, in the present invention, the heat diffusing member includes an interposed part that is interposed between the door frame and the upper edge member and is in close contact with the door frame, and the upper edge member. It is preferable to provide a standing wall that rises in a non-contact state at the opening edge of the grill cabinet along the side wall on the grill cabinet side.

  According to this, the heat transmitted from the door frame to the upper edge member by the interposed portion of the heat diffusing member is not only made uniform in the length direction of the upper edge member, but also in contact with the opening edge of the grill cabinet. A heat dissipation effect is obtained by the standing wall that stands up in a state, and the heat diffusion effect by the heat diffusion member is increased, so that deterioration of the appearance and durability of the grill door can be more reliably prevented.

  Moreover, in this invention, it is preferable that the recessed part recessed in the direction away from this grill warehouse is formed in the longitudinal direction center part in the side wall which faces the said grill warehouse of the said upper edge member. By forming the concave portion on the upper edge member, the upper edge member can be provided with a shape that is easy to use because the concave portion becomes a relief and is difficult for the user to touch. In addition, the upper edge member can reduce the contact area with the door frame in the portion where the recess is formed, and can further reduce heat transfer from the door frame.
