Description

[Detailed explanation of the idea] The present invention relates to a gas cooker.

B. Prior Art Some recent gas cookers have a lid that covers the top surface of the gas cooker connected to the gas cooker so that it can be opened and closed using a hinge mechanism or the like, for the purpose of improving aesthetics or the like.

When the gas cooker equipped with the above-mentioned lid is not in use, the lid is closed to cover dirt on the heating means such as a gas burner and the top surface of the main body of the gas cooker, thereby improving the appearance of the gas cooker.

In the above gas cooker, when the heating means is used, the lid is opened to expose the heating means, but even if phenomena such as oil splashing occur during cooking, the lid prevents stains from splashing of oil etc. Since it functions as a member, it can contribute to maintaining the aesthetic appearance of a wall surface, etc.

By the way, gas cookers with conventional lids are equipped with a locking mechanism that maintains the lid in an open position so that the lid does not close due to wind pressure or contact with the cook during cooking. However, if an attempt is made to close the lid by mistake while it is locked in the open position, problems such as damage to the locking mechanism and deformation of the lid arise.

(b) Purpose of the invention The purpose of the present invention is to provide a gas cooker having a lid mechanism that will not be damaged by the above-mentioned erroneous operation.

C. Structure of the invention The present invention provides a gas cooking device 1 in which a heating means is exposed to the top surface of the gas cooking device 1. At the same time, a spring member 5 is incorporated into the hinge mechanism 4 to always bias the lid 3 in the open direction, and a pin 7 provided at the center of the central front edge of the lid 3 is connected to the lid 3 that covers the lid 3. The lid 3 is attached to the main body of the gas cooker 1 by means of a lower hook 10 of a lock lever 8 which is attached to the lid 3 through the connector and bent inward at both ends into a hook shape, and which swings around the pin 7. The gist is a gas cooking appliance 1 provided with a lock mechanism 6 that locks and releases the lock by pushing in the upper part of the lock lever 8.

D. Embodiment FIGS. 1A and 1B are a side view and a front view illustrating the device of the present invention.

In FIGS. 1A and B, the top plate 2 of the gas cooker 1
A heating means such as a gas burner (not shown) is arranged substantially horizontally above, and a lid 3 having substantially the same dimensions as the top surface of the top plate 2 is attached to the top plate 2 .

The lid 3 is connected to the rear edge of the top plate 2 via a hinge mechanism 4 so as to be openable and closable, and the hinge mechanism 4 includes a coil spring that constantly biases the lid 3 toward the open position. A first spring member 5 such as the like is attached. Further, a locking mechanism 5 is provided at the center of the front edge of the lid 3 for locking the lid 3 to the top plate 2 in the closed position.

FIG. 2 is a partially cutaway side view illustrating the structure of the lock mechanism 6. As shown in FIG.

In FIG. 2, the locking mechanism 6 is attached to the lid 3 via a pin 7 provided in the center, has both ends bent inward into a hook shape, and swings like a seesaw with the pin 7 as the center of rotation. A lock lever 8 is provided, and when the lid body 3 is in the closed position, the lock lever 8
The closed position is maintained by a second spring member 9 which engages the lower front edge 2a of the top plate 2 with a hook portion at the lower end of the top plate 2 and urges it toward the locked position. That is, the lower hook 10 of the lock lever 8 engages with the lower front edge 2a of the top plate 2 when the lid 3 is in the closed position, and holds the lid 3 in the closed state under the bias of the second spring member 9. do. Further, the bent end of the upper end of the lock lever 8 always comes into contact with the lower surface of the lid body 3 and closes the opening of the recess 12 except when the lock lever 8 is swinging.

Hereinafter, the procedure for opening and closing the lid 3 in the device of the present invention will be explained.

When opening the lid 3 to use the gas cooker 1, the upper part 11 of the lock lever 8 is pressed in the direction shown by arrow P in FIG. Due to this pressing, the upper part 11 of the lock lever 8 is pushed into the recess 12 provided in the lid body 3, and in conjunction with this, the remaining part of the lock lever 8 swings in the direction shown by the arrow P' using the pin 7 as a fulcrum. Lower hook 1 of the lock lever 8
0 and the lower front edge 2a of the top plate 2 are released. Therefore, the lid 3 is automatically rotated to the open position by the elastic restoring force of the first spring member 5, and is held in the open position in which the heating means is exposed on the top surface of the top plate 2.

In addition, when closing the lid 3, the lid 3 is manually pushed up to near the closed position, and the lid 3 is closed while pressing the upper part 11 of the lock lever 8. When the pressing operation of the upper part 11 of the lock lever 8 is stopped after the lid body 3 is completely closed, the second spring member 9
Due to the elastic restoring force, the lock lever 8 automatically displaces its lower hook 10 toward the lock position, and finally engages the lower hook 10 with the lower front edge 2a of the top plate 2. . Therefore, the lid body 3 is connected to the first spring member 5
It is reliably locked in the closed position against the elastic restoring force in the opening direction due to

In a preferred embodiment of the present invention, the means for reinforcing the elastic restoring force by the first spring member 5 includes a spring-biased protrusion between the top plate 2 and the lid body 3, a fitting hole for the protrusion, etc. A click stop mechanism can be provided.

Further, as a further embodiment of the present invention, gas is supplied to the heating means by pressing down the lid 3 in the closing direction in conjunction with the opening/closing operation of the lid 3 in the main body of the gas cooker 1. It is also possible to install a safety device to stop the operation.

E. Effects of the invention While conventional gas cooker lids are locked in the open position, the gas cooker lid according to the present invention is locked in the closed position.
Accidents such as damage to the lock mechanism or deformation of the lid due to the closing operation of the lid in the open position can be reliably prevented.

Furthermore, the lid of the gas cooker stands upright at the rear with a hinge incorporating a spring that is always biased in the opening direction, so there is no risk of the lid closing unexpectedly due to wind etc. without causing any inconvenience,
It is also effective in preventing contamination of the rear wall of gas cookers.
Moreover, to close the lid, simply pull the lid down at the end, operate the locking mechanism using the lock lever in the center of the front with one hand, and lock it safely and securely at the bottom of the front edge, making opening and closing operations extremely convenient. , it is possible to provide an easy-to-use gas cooker.
