2. Description of the Related Art Conventionally, gas table stoves are provided with a gas grill in the center for heating and cooking foods such as fish, and when the food tray is slid toward the front while the foods are placed on a grill, the accompanying effect is increased. There has been known a type of gas grill in which a door of a gas grill automatically jumps upward, so that the door is not obstructed and the food can be easily taken out. For example, the gas grill disclosed in Japanese Utility Model Laid-Open No. 5-42912 has a grill 10 on which cooking products are placed, as shown in FIGS.
And a tray 1 which is slid out toward the front with the grill 10 placed thereon, and a burner 1 which burns gas to heat the cooked product.
5 and a grill storage 5 for storing these. The grill storage 5 includes a guide rail 6 on a bottom wall 5a thereof and a grill door 2 on a front opening side wall 7 thereof. A substantially L-shaped connecting part 12 is fixed to both sides inside the grill door 2, and one end of the connecting part 12 is a support shaft 1 serving as a pivot of the connecting part 12.
1 is provided with a shaft hole 12a at the other end. The support shaft 11 is
Both ends of the arm portion 3 bent in a U-shape are fitted into the shaft hole 12 a while being fixed to the front opening side wall 7. A slot-shaped guide hole 33 is opened in the back of the grill storage side wall 5b in the sliding direction corresponding to the intermediate straight portion 3b of the arm portion 3, and the straight portion 3b is inserted. A hook 14 is provided in the front of the grill storage side wall 5b. A spring 4 is stretched between the linear portion 3b of the arm 3 and the hook 14 and the grill door 2 is flipped up through the arm 3. Bias in the direction. The straight portion 3b of the arm portion 3 abuts on the back surface 1a of the tray 1, and the tray 1 is also urged in the pulling-out direction. The bottom wall 5a at the entrance of the grill 5 is provided with a protruding stopper 20 for restricting the tray 1 from jumping out by the urging force of the spring 4 and determining the storage position. The spring 4 prevents the grill door 2 from returning downward and closing when the pan 1 is pulled out to the front and the grill door 2 is flipped up with the support shaft 11 as a fulcrum of rotation. Power is needed. Therefore, it is designed so that a predetermined force (a load force due to the weight of the grill door 2 or more) is urged at the point where the tray 1 is pulled out to the predetermined position. With such a configuration, the tray 1 slides along the guide rail 6 and the grill door 20 automatically opens and closes accordingly, so that the tray 1 can be easily put in and out of the grill storage 5.

[0003]

However, in order to stably hold the grilled door 2 that has been flipped up, it is necessary to increase the urging force of the spring 4. Then, the saucer 1 must be pushed in so as to resist the force. In particular, the closer the position is to the storage position, the stronger the tension of the spring becomes, and a greater pressing force must be applied. Also, a stopper 20 is provided so that the tray 1 does not protrude from the storage position toward the front,
The configuration becomes complicated. The grill opening and closing device of the present invention,
It is an object of the present invention to solve the above problems and to obtain good operability even with a simple configuration.

According to a first aspect of the present invention, there is provided a door opening / closing apparatus for a grill storage which is provided at a front opening of the grill storage and rotates vertically about a support shaft as a fulcrum. A grill door that opens and closes in a one-sided manner, a tray that slides in and out of the grill chamber in the reciprocating direction, and a pan that slides in and out of the grill chamber; and a pivot point that is rotatably attached to a fulcrum at a position different from the spindle of the grill door. An arm portion extending in the depth direction of the grill warehouse contacts a back surface of the pan to link an opening / closing operation of the grill door and an advance / retreat operation of the pan, and an arm of the coupling member provided on the back surface of the pan And an opening for opening the side wall of the grill warehouse in the direction of the pan forward and backward, and the arm of the connecting member is engaged with the pan by a stroke from fully closed to fully open of the grill door. Guide to engage the joint A guide hole that is inclined from the direction in which the pan moves only in the vicinity of the opening position of the grill door, thereby guiding the arm section to the inclined portion while the pan is being pulled out, and engaging the arm section with the engaging section. And disengagement with the arm, and support the arm portion with the inclined portion to hold the grill door fully open.

In the grill opening / closing apparatus of the present invention having the above-described structure, when the tray is slid into and out of the grill storage, the grill door is automatically opened and closed in conjunction with the sliding of the tray. The grill door pivots up and down about a support shaft at a front opening of the grill storage and opens and closes in a one-sided manner. The saucer interlocks the grill door by engaging the arm of the connecting member with the engaging portion provided on the back surface, and the arm of the connecting member has an elongated hole (guide hole) opened in the grill warehouse side wall. Slide. The arm slides through the guide hole, and the grille door opens and closes in that section from fully open to fully closed. At this time, since the guide hole for guiding the arm portion of the connecting member is inclined only in the vicinity of the open position from the pan advance / retreat direction, by guiding the connecting member to the inclined portion, the grill door is fully opened and the arm portion is further opened. Even when the engagement with the engaging portion is released, the load from the connecting member is received by the side wall of the guide hole, so that the connecting member does not return in the pan closing direction with a load about the same as the weight of the door. That is, it is possible to prevent the connecting member from automatically moving from the open position and to close the grill door, and it is possible to hold the door in a fully opened state. Therefore, when the tray is pulled out of the grill storage or taken out of the grill storage, the grill door is kept open, so that the grill door is not obstructed and simple. Also, when the tray is re-inserted into the grill storage, the grill door is similarly not obstructed and the tray is slid to the back of the grill storage. The arm portion is engaged, the arm portion returns from the inclined portion of the guide hole to the tray receiving / retreating direction portion, and the grill door closes while storing the tray, so that it is easy to use. In a conventional automatic door opening / closing device of the type urged in the door opening direction by a spring, a mechanism for locking the movement of the pan at the storage position of the pan is provided. Even with a simple configuration without a mechanism, it is possible to automatically open and close the grill door and hold it fully open.
