TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gas grill door opening / closing device that heats a cooking product such as fish in a grill storage.
[0002]
[Prior art]
Conventionally, gas table stoves are equipped with a gas grill in the center that can heat and cook cooked items such as fish.When the dish is slid forward while the cooked item is placed on the grill, the gas grill door automatically moves accordingly. There is a known type that can easily take out a cooked product without being obstructed by a door because the door jumps upward.
For example, as shown in FIGS. 6, 7 and 8, a gas grill disclosed in Japanese Utility Model Laid-Open No. 5-42912 has a grill 10 on which cooking items are placed, and a tray 1 which is slid forward with the grill 10 being pulled out. And a burner 15 that heats the cooked product by burning the gas, and a grill storage 5 for accommodating them. The grill storage 5 includes a guide rail 6 on a bottom wall 5a and a grill door 2 on a front opening side wall 7 thereof.
A substantially L-shaped connecting member 12 is fixed to both sides of the inside of the grill door 2, and at one end of the connecting member 12, a support shaft 11 serving as a rotation fulcrum of the connecting member 12 is provided, and at the other end, a shaft hole is provided. 12a are provided. The support shaft 11 is supported by the front opening side wall 7, and both ends of the arm portion 3 bent in a U-shape are fitted into the shaft holes 12a. An elongated hole-shaped guide hole 33 is opened in the sliding direction in the inner side of the grill storage side wall 5b in correspondence with the intermediate straight portion 3b of the arm portion 3, and the straight portion 3b is inserted.
A hook 14 is provided on the front side of the grill storage side wall 5b. A spring 4 is stretched between the straight 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 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 upward with the support shaft 11 as a fulcrum of rotation. Power is needed. Therefore, it is designed such that a predetermined force (a load force due to the own 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 taken in and out of the grill storage 5.
[0003]
[Problems to be solved by the invention]
However, in order to stably hold the flipped-up grill door 2, it is necessary to increase the urging force of the spring 4, and if it is too strong, the saucer 1 gets over the stopper 20 due to slight vibration or the like. There is a danger that it will jump out of the storage position. In addition, in order to securely lock the stopper 20, it is necessary for the tray 1 to largely climb over the protrusion of the lock, and the operability at that time is not good.
An object of the present invention is to solve the above-mentioned problem and to obtain stable operability.
[0004]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a grill door door opening / closing apparatus, which is provided at a front opening of the grill chamber and pivots up and down about a support shaft to open and close in a one-sided manner. An urging means for urging the grill door in the opening direction, a tray sliding in and out of the grill chamber in the reciprocating direction, and a pan which is rotatable about a fulcrum different from the spindle of the grill door. A connecting member attached to the fulcrum and extending from the fulcrum in the depth direction of the grill warehouse to abut against the back surface of the pan to interlock the opening / closing operation of the grill door and the advancing / retreating operation of the pan; A grill chamber having a guide hole that opens in a long hole shape extending in the reciprocating direction and guides the arm portion of the connecting member so as to abut on the back surface of the tray with a stroke from full closing to full opening of the grill door. Door opening and closing device, Serial guide hole, and summarized in that the forming direction and a shape which is inclined from the pan forward and backward direction only near the closed position of the grill door.
[0005]
With the grill opening / closing door opening / closing device of the present invention having the above-described configuration, the grill door is automatically opened and closed in conjunction with the sliding of the pan when the pan is slid in the advancing / retreating direction and put in and out of the grill storage. The grill door is vertically urged in the opening direction at the front opening of the grill warehouse while being urged in the opening direction by the urging means, and opens and closes in a one-way manner with the support shaft as a fulcrum. The tray interlocks the grill door by abutting the arm portion of the connecting member on the back surface, and the arm portion slides in an elongated hole (guide hole) opened in the grill warehouse side wall and extending in the tray advancing / retreating direction.
The arm slides through the guide hole, and the grille door opens and closes in that section from fully open to fully closed. The grill door is constantly urged in the opening direction by the urging means, and even in the closed position, a load is applied to the connecting member in the opening direction. However, since the guide hole guiding the arm portion of the connecting member is inclined only in the vicinity of the closed position from the pan moving direction, this load is mostly received by the side wall of the long hole and moves in the pan moving direction. The added amount is reduced. Therefore, it is possible to prevent the connecting member from being moved from the closed position due to the load in the tray moving direction and the tray being popped out or the grill door being opened due to a slight vibration or the like.
When the urging force is large, for example, a mechanism for locking the movement of the pan at the grill cabinet closed position may be provided. In such a case, the load applied to the lock mechanism is reduced.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of a grille door opening / closing device of the present invention will be described below with reference to the drawings.
1 to 5 are schematic configuration diagrams of an operation main portion of a door opening / closing device of a gas grill 40 as a first embodiment. FIG. 1 is a side view, and FIG. FIG. 3 is an explanatory view of a state in which the tray 1 is pulled out to the front, FIG. 4 is a front sectional view, and FIG. 5 is a plan view. Since the gas grill 40 differs from the conventional gas grill described above only in the shape of the guide hole 13 of the grill storage side wall 5b, in order to avoid duplication, the same components are given the same reference numerals and detailed description is omitted.
A substantially L-shaped connecting member 12 is fixed to the inside of the grill door 2 of the gas grill 40, and at one end of the connecting member 12, a support shaft 11 serving as a pivot point of the connecting member 12 is provided, and at the other end, a shaft hole is provided. 12a are provided. The support shaft 11 is supported by the front opening side wall 7, and both ends of the arm portion 3 bent in a U-shape are fitted into the shaft holes 12a. An elongated guide hole 13 is opened in the inner side of the grill storage side wall 5b in the sliding direction corresponding to the middle straight portion 3b of the arm portion 3, and the straight portion 3b is inserted (see FIGS. 2 and 3). . The guide hole 13 is formed as a substantially L-shaped long hole in which a slide portion 13a extending in the slide direction and an inclined portion 13b whose tip changes its direction from the slide direction and is inclined upward.
[0007]
When the tray 1 is pulled out toward the user (FIG. 2 → FIG. 3), the grill door 2 starts to open, and in a fully opened state, the linear portion 3b of the arm portion 3 fits into the end of the slide portion 13a, and further movement is performed. Will be suspended. The pan 1 is separated from the linear portion 3b of the arm 3 and further moves to a position (not shown).
On the other hand, in a state where the tray 1 is pushed all the way back, as shown in FIG. 2, the linear portion 3b of the arm portion 3 fits into the end of the inclined portion 13b, the spring 4 becomes the longest, and the linear portion 3b is moved forward ( The maximum load is applied to the straight portion 3b by urging in the leftward direction in FIG. At this time, since the inclined portion 13b changes the direction from the sliding direction and is inclined, most of the biasing force is received by the hole wall of the guide hole 13, and the component force in the direction parallel to the hole wall is small. Therefore, the force applied to the back surface 1a at the back of the saucer 1 (the force for pulling the saucer 1 forward) when the linear portion 3b attempts to return to the inclined portion is also reduced. With such a small force, the pan 1 does not move due to the stopper 20 that locks the movement of the pan 1, so that the pan 1 jumps out or the grill door 2 opens due to the movement of the arm 3 from the closed position. Is prevented.
Further, at the position where the grill door 20 is closed, a large force is not required for the lock, and the lock is stabilized.
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, in this embodiment, the guide hole 13 is substantially L-shaped (the inclined portion 13b is inclined upward), but may be inverted L-shaped (the inclined portion is inclined downward). Further, although the straight portion 3b of the arm portion 3 bent in a U-shape is inserted into the guide hole 13, the shape is not limited to such a shape, and a shape separated right and left without the straight portion 3b may be used. In this case, the arm portion 3 is formed of two right and left arms which are bent at right angles, and each of which is inserted into the guide hole 13 and abuts on the back surface 1 a of the tray 1. There is an advantage that the configuration of the unit 3 is simplified.
[0008]
【The invention's effect】
In the grill storage door opening and closing device of the present invention, in the closed position, most of the load urged in the opening direction of the grill door is received by the inclined guide hole, and the force for moving the tray is reduced. Therefore, it is possible to prevent the tray from jumping out and the grill door from being opened. Also, when the lock mechanism is provided on the tray, a large force is not required for locking. Therefore, it is safe, easy to use, and has improved durability.
