Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a tower for household electric kotatsu.

(Prior art) Conventional household electric kotatsu that use an infrared heater as a heat source, as seen in Japanese Utility Model Application Publication No. 59-9232, have an infrared heater covered with a protective net on the bottom surface of the top frame of the tower body. Since they are usually installed facing downwards, the internal space of the tower body becomes narrower due to the infrared heaters.

(Problem that the invention aims to solve) By the way, the height of a typical Yagura Kotatsu is about 36 to 42 cm, which is about the same as the height of a chiyabudai, so the distance between the protective net of the infrared heater and the floor is about 20 cm. When I tried to cross my legs or move my legs under the kotatsu, my legs touched the protective net, making it uncomfortable.

(Means for Solving the Problems) The present invention relates to an electric kotatsu tower that solves the above-mentioned problems.A window hole is provided in the ceiling frame of the tower body, and a reverse side for storing a heat source is installed in the window hole. The box body is installed with its upper part including its heat shielding upper base rising above the top surface of the ceiling frame part, and the upper part of the inverted box body for storing heat sources is attached to the bottom part of the top frame part of the tower main body. The device is characterized in that it is mounted and supported by a top plate having a recess into which it is loosely fitted.

(Function) This kind of electric kotatsu tower is made by storing a heat source such as an infrared heater in the inverted box for storing the heat source, and then removing the top plate, covering the main body of the tower with a kotatsu futon, and placing the ceiling on top of it. Just put a board on it and use it.

(Embodiment) Next, the present invention will be explained in detail with reference to the illustrated embodiment. 1 is a tower main body whose wall thickness is approximately 2
A window hole 3 of about 35 cm square for housing a heat source is provided in the center of the ceiling frame part 2, which is about 3.5 cm square. Reference numeral 4 is an inverted box for storing a heat source attached to the window hole 3, and the upper opening of the rectangular wooden frame with a height of approximately 4 cm is closed with a heat-insulating upper bottom 5 such as a heat-resistant board. , about 2 cm of the upper part 4a is the top frame part 2
It is raised from the top of the. 6 Hayagura main body 1
The top plate is mounted and supported on the top surface of the top frame portion 2 of the device, and a peripheral frame material 6b with a thickness of about 2 cm is fixed to the lower surface periphery of the top plate main body 6a with a thickness of about 2 cm. It has a recess 7 into which the upper part 4a of the box body 4 is loosely fitted. In addition, in the first embodiment shown in FIG.
and a cord storage part 8, and the four corners thereof are attached to the upper ends of the legs 9 using screws 10 and engaging pins 11. However, in the second embodiment shown in FIG. An engagement groove is provided in the middle of the girder 12 that connects the heat source 9, and the spar 9 is attached by engaging the peripheral edge of the plate material provided with the window hole 3 for attaching the heat source and the cord storage section 8.

With this structure, the heat source is stored in the inverted box 4 for storing the heat source, making it an electric kotatsu, and the top plate 6 is used as an electric kotatsu.
When used by removing the kotatsu futon from the tower body 1 and placing the top board 6 on top of it, the heat source is attached to the window hole 3 provided in the center of the top frame 2, and the upper end is connected to the top frame. 2, the lower surface of the heat source does not protrude further downward than the lower surface of the ceiling frame 2, thereby reducing the space between the floor and the heat source. This has the advantage of creating ample space within the tower body 1.
Further, since the heat shielding upper base 5 is interposed between the heat source and the top plate 6, the top plate 6 will not be overheated.

(Effect of the invention) As is clear from the above description, the present invention has an inverted box body for storing a heat source attached to a window hole provided in the ceiling frame so that its upper end rises above the ceiling frame. The heat source is installed inside the inverted box to form a sufficient distance between the heat source and the floor, and the upper part of the inverted box for housing the heat source is raised from the top of the ceiling frame by an amount corresponding to this height. By absorbing it into the concave part of the recessed top plate, the overall height remains the same as the conventional one.It has the advantage of being simple in structure and can be provided at low cost, but it also has the problems of conventional electric kotatsu towers. The practical value is extremely great as it solves the problem.
