Description

[Detailed description of the invention] (Field of industrial application) The present invention is a locking device for a hot plate in a grilled food cooker, which is provided to prevent falling objects such as juice from cooking from directly touching the heat source. Regarding.

(Prior art) A plurality of burners and other elongated heat sources are arranged in parallel at intervals in the main body of the device, and a plurality of hot plates made of glass, metal, etc. The heating plate is installed on a pair of flanges facing each other in the longitudinal direction of the plate, and each heating plate is locked in a position covering each heat source, thereby preventing falling objects such as juice from cooking from directly touching the heat source. BACKGROUND OF THE INVENTION Locking devices for hot plates in grill cookers have been known for some time. In such a locking device, if the hot plate is simply installed on a flat flange, the position of the hot plate may shift, so a locking part is provided on the flange to lock the hot plate in a position that covers the heat source. There is. For example, as shown in FIG. 5, such a locking portion may be formed by welding a U-shaped member c with an open top surface to a flange b, and forming a locking portion by fitting a hot plate into the opening of the U-shaped member c. There are some that are designed to be locked.

(Problems to be Solved by the Invention) When the heat source is activated for cooking, the flange b is heated by the heat source, so the flange b thermally expands. By the way, in the conventional device equipped with the locking part shown above, the flange b protrudes from the main body, so the base part is restrained by the main body but the edge is not. Due to stress, it deforms significantly in a waving manner upward or downward. As a result, the hot plate supported by the flange b also displaces up and down, causing the problem that the position of the hot plate relative to the food to be cooked and the heat source deviates from the preset position. In addition, a plurality of U-shaped members c are attached to the flange b.
Since the parts must be welded to each other, there are also problems in that the number of parts is large and the machining process is complicated.

(Means for Solving the Problems) The present invention aims to provide a device that eliminates the above-mentioned disadvantages, and includes a plurality of burners and other elongated heat sources arranged side by side at intervals in the main body of the device. ,
A plurality of hot plates made of glass, metal, etc. are installed on a pair of flanges that protrude from the inner surface of the device body and face each other in the longitudinal direction of the heat source, and the respective locking portions provided on the flanges The hot plate is locked in a position covering each heat source, characterized in that each locking part is formed with a concave part or a convex part that is integrally formed with the flange and reaches the edge of the flange. .

(Function) Even if the flange is heated and thermal stress is applied to it, the thermal stress is absorbed by each locking part consisting of a concave or convex part that reaches the edge of the flange, and the edge of the flange does not curve upward or downward. .

(Example) Referring to the drawings, 1 indicates a rectangular instrument main body with an open top surface, 2 indicates a plurality of elongated heat sources longitudinally extending in the front and back direction provided in the instrument main body 1, and the heat sources 2 Three pipe-type Bunsen burners 2a are arranged on the right side when viewed from the front, and three ceramic plate-type infrared burners 2b are arranged side by side with a gap between them on the left side when viewed from the front. A hot plate 3a made of a metal plate is arranged above each pipe burner 2a so as to cover the upper surface thereof, and an infrared transmitting glass plate 3a is arranged above each infrared burner 2b so as to cover the upper surface thereof. A hot plate 3b is provided to prevent falling objects such as juice from cooking from directly touching each burner 2a, 2b. Each hot plate 3a, 3b is attached to the appliance body 1 by a pair of flanges 1b, 1b protruding from the top plate 1a of the appliance body 1 so as to face each other in the longitudinal direction of the heat source 2. A plurality of convex portions 4, 4 that rise gently by drawing process using a press are formed so as to reach the edges of the flanges 1b, 1b, and this pair of front and rear flanges 1b, 1b are formed.
This is done by erecting the hot plates 3a, 3b such that both ends of the hot plates 3a, 3b are engaged with the front and rear convex portions 4, 4.

In this case, even if a large number of locking portions are provided, all the locking portions can be provided in one step by press working, etc., and the processing process does not become complicated.
Further, since the thermal expansion of the flanges 1b, 1b can be absorbed by each of the convex portions 4, 4, which are locking portions, the flanges 1b, 1b are not bent or deformed vertically. Further, since the convex portions 4, 4 rise gently from the flanges 1b, 1b, the flanges 1b, 1b
can be easily cleaned. Furthermore, since the convex portions 4, 4 are formed by drawing, they serve as reinforcement for the flanges 1b, 1b.

In addition, 5 indicates a gridiron which is provided above the hot plates 3a, 3b and on which the food to be cooked is placed. 2 can be adjusted. Also, 6 is a Bunsen burner 2a and an infrared burner 2b.
and indicate a partition plate installed in an adjacent part. By the way, the top plate 1a has screws 8 inserted through the daruma holes 7.
so that it can be detachably fixed to the instrument body 1,
The entire top plate 1a is prevented from being deformed such as warping due to thermal expansion.

(Effect of the invention) As described above, according to the invention, the flange has
A concave or convex portion reaching the edge is integrally formed,
By using the concave portions or convex portions as locking portions, even if thermal stress is applied to the flange, the thermal stress is absorbed by each locking portion, and even if the flange is heated due to the start of operation of a heat source, etc., the end of the flange is The edges do not curve upward or downward, and the position of the hot plate relative to the food to be cooked or the heat source does not deviate from the preset position. In addition, even when a large number of locking portions are provided, all the locking portions can be formed in one step by press working, etc., and the manufacturing steps are not complicated and costs can be reduced.
