Description

[Detailed description of the invention] This invention relates to a heat-retaining mat that is designed to block heat radiated from the surface of a liquid such as a bathtub, and further relates to a heat-retaining mat that can be folded compactly when not in use. .

Conventionally, bathtub lids have been used in bathtubs, but since the lids are used by being stretched between the edges of the bathtub, a gap is created between the lid and the surface of the liquid such as hot water in the bathtub, which prevents leakage from the liquid surface. Heat dissipation occurred and much of the heat was wasted and was released into the air gap. Furthermore, the lid itself was not made with sufficient consideration to retain the heat of the liquid in the bathtub, so it lacked airtightness and was also made of inadequate material, allowing a lot of heat to be released into the atmosphere. In addition, this invention solves the above-mentioned drawbacks by selecting a shape and material that are placed directly on the surface of the liquid in the tank and are extremely effective in preventing heat from being released into the atmosphere, as well as transporting the liquid. This relates to a heat insulating mat that can be folded for convenient storage and storage, and can not only shorten the heating time for boiling water, but also delay the cooling of the water for those who use the water at different times. The purpose is to be able to fold it into a compact size when not in use, and to be extremely easy to handle.

This will be explained below with reference to the drawings.

FIG. 1 is a cross-sectional view of a heat-retaining mat 1 of this invention. The thickness of the cross-section is about 30 mm, and the core material is styrofoam 2, and the surface is surrounded by a vinyl sheet 3. Styrofoam 2
It has excellent heat insulation properties and is lightweight, so it has a heat insulation effect and is easy to handle. Furthermore, since the surface is surrounded by a vinyl sheet, even if dirt or dust is attached, it can be easily removed.

The above Styrofoam 2 is adjacent to other Styrofoam 2', 2'' on both sides, and is connected by connecting vinyl sheets 6, 7 at the lower end 4 on one side and at the upper end 5 on the other side. The connecting vinyl sheets 6 and 7 are preferably formed integrally with the vinyl sheet 3, and the upper and lower parts are joined by welding, sewing 8, 9, etc. The joining parts are flexible. Since there are bent parts 10 and 11, the second
It can be bent as shown in the figure. The appropriate width of the bent portion is about 15 to 30 mm so that welding and sewing can be done easily. The heat-retaining mat 1 having the above structure can be placed directly on the surface of a liquid such as hot water in a bathtub 12, as shown in FIG.

Due to the bent portions 10 and 11, even if the width of the bathtub 12 in the lateral direction is slightly different, it can be adjusted by the width of the bent portion.

4 shows another embodiment, in which a flexible fin 13 is formed continuously with the vinyl sheet 3 over the entire lower end of the thermal mat 1 in the lengthwise and widthwise directions, making it possible to fully accommodate bathtubs of all sizes, and by folding the fin 13 along the bathtub wall toward the bottom of the bathtub, it is possible to more effectively prevent heat from escaping from the corners of the bathtub. Also, a cut section 14 is formed in the fin 13 to enable it to be folded in the same manner as above.

This invention having the above-mentioned configuration can efficiently prevent the temperature of the liquid in the bathtub from dropping during boiling water, and can efficiently block heat dissipation from the surface of the liquid after boiling water. In addition, if the heat retention mat 1 body is bent at the bent part 1
It is easy to handle because it can be bent at 0.11 degrees, and even if the size of the bathtub is slightly different, it can be adjusted using the bent portion.

Furthermore, since flexible fins 13 are formed on the entire vertical and horizontal ends of the heat-insulating mat 1, it can accommodate bathtubs of different sizes than those mentioned above.
This effectively prevents heat dissipation within the bathtub.
