Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a heat-retaining basket used to store and keep warm objects such as bread.

PRIOR ART AND PROBLEMS This type of heat-retaining basket has heretofore been used exclusively for this purpose, and has a form and structure that cannot be applied to keeping boiled food in a cooking container warm. On the other hand, there is also a thermal insulation plate that holds boiled food in a cooking container and keeps it warm, but this is not suitable for storing bread in its own regular container and keeping it warm. do not have. Even if bread is placed in a cooking container and placed on a heat insulating plate to keep it warm, it does not look good.

Means for Solving the Problem Therefore, in this invention, in order to solve the above problem, a heat insulating plate having a heat insulating heating surface on the upper surface,
A container for objects to be kept warm, which has a storage chamber for storing objects to be kept warm, and a skirt wall that is bent outward from an upward opening thereof to a side circumference of the object storage chamber, Attachment/detachment is performed by engaging the engaging part provided at the lower edge of the skirt wall with the locking part on the heat insulating plate side while the bottom of the heat insulating object storage chamber is in contact with the heat insulating heating surface of the heat insulating plate. Can be freely combined and integrated.

Function The container for objects to be kept warm is formed by the engagement part provided at the lower edge of the skirt wall that is bent outward and downward from the upward opening of the object storage chamber and the locking part on the heat insulation plate side. The heat insulating plate is removably connected and integrated with the heat insulating plate at the bottom of the object storage chamber and receives heat conduction from the heating surface of the heat insulating plate to keep the stored object warm.

Therefore, since a heat insulating space is formed between the skirt wall and the side circumference of the object storage chamber, the function of the heat insulating plate as the heat source for insulating the object container is enhanced. This heat insulating plate can be separated from the container for the object to be kept warm and used alone to receive boiled food and the like together with the cooking container and keep it warm. In addition, the container for keeping warm objects separated from the heat insulating plate can also be used to store uncooked bread, etc., but by forming the skirt wall with a material with low thermal conductivity and heat insulation, the container itself can be It can also be used as a handle.

In either case, the skirt wall has a simple structure of just bending the periphery of the object to be kept warm, and can also be used as an exterior case to cover the periphery of the object to be kept warm.

Embodiment To explain the first embodiment shown in FIG. In this placed state, the heat insulating plate A and the container B for the object to be kept warm are integrally connected to each other by the outer circumferential handle 4 of the heat insulating plate A so as to be detachable from each other.

The heat-retaining plate A has a heat-retaining heating plate 7 applied from below to the upper opening edge 6 of a frame body 5 made of synthetic resin, on which the handle 4 is integrally formed on both sides, and a surface heater is installed on the lower surface of the heat-retaining heating plate 7. 8 and is pushed upward and held by a leaf spring 11 acting between it and a heat shield plate 10 screwed 9 to the frame body 5. Legs 12 are integrally molded at several locations on the lower surface of the outer periphery of the frame 5, and rubber seats 1 are attached to the lower ends of the legs 12.

The engaging tool 20 is made of metal or other elastic material, and has an operating piece 20b integrally formed in a V-shaped bent portion.

If the skirt wall 15 around the heated object storage chamber 2 is made of synthetic resin, glass, or other suitable low thermal conductivity and heat insulating material, heat radiation to the surroundings can be suppressed, and the skirt wall 15 can be separated from the heated object container B. When used alone, it can be used as a handle for the container itself. bottom 3
In this case, unevenness 21 is formed to prevent objects to be kept warm, such as bread, from coming into close contact with each other. 22 is a heater protection plate.
