Description

[Detailed description of the invention] This invention is a heat insulating frame used for gas stoves, which prevents condiment containers, chopsticks, etc. placed on the gas stove from being damaged by the heat of the cooking flames or catching fire. The purpose is to prevent accidents and increase the efficiency of heat utilization during cooking.

Traditionally, people often cook with plastic seasoning containers and chopsticks left on the gas stove, and these items can get damaged by the heat of the cooking flames or burst into flames if they are carelessly left on the stove for a long time. There were fears that such things would occur.

This invention was made to prevent the above-mentioned accidents and also to improve the heat utilization efficiency during cooking.Next, the details of this invention will be explained based on the drawings which are examples.

Reference numeral 1 denotes a heat insulating frame for a gas table in the shape of an inverted pyramidal cylindrical cylinder with smooth corners, and is composed of 22 rear frame members and 32 front frame members having substantially the same shape. The rear frame member 2 is made of a metal plate or thick metal foil,
It is formed by protruding locking pieces 4 from both ends of the upper and lower side edges of a dogleg-shaped member having the required length and width, and opening a plurality of air holes 6 at appropriate positions on the plate surface (foil surface). The front frame member 3 is
The shape of the locking piece 4 is such that the locking piece 4 projects to the upper edge of the narrow portion 5 with the upper edge of one end of the rear frame member 2 removed, and the shape other than this portion is the same as that of the rear frame member 2. Locking piece 4
These protrude like tongues from the upper and lower edges, but depending on the condition of the frame material, they may be formed during molding, or as shown in Figure 4, notches 7 may be formed at key points on the upper and lower edges of the frame member, and the gaps between the notches may be formed. It is also possible to form the shape by bending the side edges of the shape. The narrow part 5 is a part where a frame edge recess is formed to prevent the handle from getting stuck when cooking using a frying pan or the like, and the shape of the part 5 is set so that the required recess can be formed even when there is the most overlap. The air holes 6 are a plurality of small holes opened in the lower frame surface excluding both ends and the center of the frame member. In constructing the heat shielding frame 1, the center portions of the frame members 2, 2, 3, and 3 are smoothly bent into an L shape, and both ends of these are overlapped, and the inner frame members to be overlapped are The overlapping portion is configured to be slidable by folding the locking pieces 4 outward and the locking pieces 4 of the outer frame member inward.
(The front frame members 3, 3 are bent in opposite directions when bent into the L shape so that the narrow portions 5 of each other can be overlapped.) This invention has the above-mentioned shape and structure, and is suitable for gas stoves. When in use, the size of the frame is adjusted by sliding the overlapping part of the heat shield frame 1 so that an appropriate space can be provided around the side of the cooking pot etc. to provide an exhaust path for combustion gas. , place it on the gas table with the narrow part 5 facing forward.

This prevents heat radiation of the combustion gas rising and being discharged from the side periphery of the pot to the outside of the heat shield frame 1, and prevents heat damage and flames of seasoning containers, chopsticks, etc. placed nearby. In addition, the heat shield frame 1 has a frame surface inclined outward to facilitate upward discharge of combustion gas, and by using this heat shield frame 1, discharge of combustion gas is prevented and incomplete combustion in the combustion section is prevented. I don't even invite you. In addition, the heat shield frame blocks heat radiation outside the frame, improving heat utilization efficiency during cooking.

On the other hand, as the combustion gas rising inside the frame is discharged, the heat shield frame 1 that blocks the flame heat of the combustion gas sucks cold air from outside the frame through a plurality of air holes 6 opened in the frame surface, and this air flows into the frame. Since it rises while cooling the inner surface, it does not easily reach a high temperature state where it loses its heat shielding effect even during long cooking.

As mentioned above, this invention is effective in heat shielding and improving heat utilization efficiency, and the three-dimensional heat shielding frame 1 can be constructed from two types of planar frame members with approximately the same shape. It has the advantage of being simple to manufacture and easy to provide, such as being able to accommodate any type of cooking pot through sliding adjustment, and has great practical effects.

Claims (1)

[Scope of utility model registration request] A dogleg-shaped member having the required length and width, formed from a metal plate or thick metal foil, is provided with locking pieces 4 at both ends of the upper and lower edges, and a plurality of air holes are provided at appropriate locations on the plate surface (foil surface). It consists of 22 rear frame members each having a hole 6, and 32 front frame members each having a locking piece 4 on the upper edge of a narrow part 5 with the upper edge of one end of the member 2 removed. When constructing the heat shielding frame 1 having an inverted pyramidal cylindrical shape, the central portions of the frame members 2, 2, 3, and 3 are smoothly bent into an L shape, and both ends of these are overlapped, and the overlapping inner frame members are A heat insulating frame for a gas table characterized in that the locking pieces 4 of the outer frame member are folded back outward and the locking pieces 4 of the outer frame member are folded back inward to make the overlapping portion slidable.
