  In view of the above points, an object of the present invention is to provide a grill door that can smoothly open and close the grill door by reducing discomfort due to heat received by a user touching the panel member.

  In order to achieve such an object, the present invention is a grill door that is provided on a stove with a grill and is capable of opening and closing the front opening of the grill cabinet, and a window portion that allows the inside of the grill cabinet to be viewed from the outside is formed. A door frame, a glass plate held in the window portion of the door frame, a panel member connected to the door frame located on the lower edge side of the glass plate, and provided in front of the panel member In the grill door comprising a gripping member, the gripping member extends from the panel member with a predetermined gap and extends along the panel member, and from both ends of the gripping part toward the panel member. And a connecting portion connected to the panel member at the front end thereof, wherein the panel member includes a hollow portion that forms a heat insulating air layer inside the front side of the gripping member side. .

  According to the present invention, since the heat insulating air layer is formed by the hollow portion in the interior of the panel member near the front surface, the heat received from the heat source in the grill box is suppressed from being transmitted to the front surface side of the panel member. It is possible to prevent the surface of the panel member on the holding member side from becoming high temperature. Thus, even when the fingertip touches the panel member when gripping the grip portion of the grip member, the user can perform the opening / closing operation of the grill door without causing discomfort due to heat.

  In the present invention, the panel member includes a base portion that supports the gripping member by connecting the connecting portions of the gripping member, and a front plate that covers a front surface of the base portion on the gripping member side, The portion is formed by covering a recess formed on the front surface of the base portion with the front plate.

  According to the present invention, since the heat insulating air layer is formed by the concave portion between the front plate and the base portion, the heat received from the heat source in the grill box is suppressed from being transmitted from the base portion to the front plate. And the front plate can be prevented from becoming hot. As a result, even when the fingertip touches the front plate when gripping the grip portion of the grip member, the user can open and close the grill door without causing discomfort due to heat. In addition, the hollow portion can be formed simply by forming a recess in the base portion and covering it with a front plate, and the structure is simple and the manufacture is easy.

  Moreover, in this invention, it is preferable that the said hollow part is formed in the position facing the grip part of the said holding member. When the user grips the grip portion of the grip member to open and close the grill door, the user's fingertip is most likely to touch the front surface of the panel member at a position facing the grip portion of the grip member. Therefore, by forming the hollow portion at a position where the fingertip of the user is most easily touched on the panel member, i.e., at a position facing the grip portion of the gripping member, the base portion is heated by heat received from the heat source in the grill box. Even if it becomes hot, the heat transfer to the front surface of the panel member at the position where the user's fingertip is most easily touched can be suppressed by the heat insulating air layer in the hollow portion.

  And when a hollow part is comprised with the recessed part of a base | substrate part and the front plate which covers this recessed part, it provides a recessed part with respect to the whole front side of a base | substrate part by providing the air layer for heat insulation by a recessed part only in a required position. Can be made relatively small, and a decrease in strength of the base body can be prevented. Furthermore, a surface other than the concave portion on the front side of the base portion can be obtained relatively wide. For example, when the front plate is bonded to the base portion using a surface other than the concave portion, the adhesive is applied to a relatively wide range. Therefore, it is advantageous that the attachment state of the front plate to the base body can be strengthened.

  In the present invention, it is preferable that the panel member is provided with an air flow passage through which air inside the hollow portion can be discharged to the outside of the panel member. According to this, when the heat from the grill is transmitted to the panel member and the air in the hollow portion is expanded, the expanded air can be released to the outside of the panel member through the air flow passage. Therefore, for example, the deformation of the panel member accompanying the expansion of air in the hollow portion can be prevented, and the appearance of the panel member can be kept good.
