Description

[Detailed explanation of the idea] This invention relates to a home kotatsu.

A conventional, common home kotatsu has pillars at each of the four outer corners of the lower surface of the top plate, and an infrared lamp type heater attached to the center of the lower surface of the top plate. However, with this conventional home kotatsu, there were problems such as the pillars getting in the way and the heater's guard net hitting the feet when inserting one's feet into the kotatsu or lying down inside the kotatsu. . Particularly when a large number of people (for example, five or more people) are entering the kotatsu at the same time and they have to insert their feet from near the corners, the pillars get in the way and make it difficult to enter. In addition, with home kotatsu that use infrared lamp heaters, there is a problem that the temperature difference between the location near the heater and the location far away is too large, so if you go to the location directly below the heater, only that part becomes too hot.
There was also the problem that exposing bare feet to the heat rays of infrared lamps for long periods of time could cause minor burns.

In addition, there have traditionally been kotatsu types in which the main body of the kotatsu is installed on a concave space formed in the floor for placing the feet, but with such type of kotatsu, the place where the home kotatsu can be installed is limited. As I put it away,
There was a problem in that the construction work to form the recessed chamber in the floor was troublesome.

In view of the above-mentioned problems with the conventional home kotatsu, this invention has a relatively simple structure, and also prevents the pillars and heater guard nets from getting in the way when entering or entering the kotatsu. To provide a home kotatsu which can be heated to an appropriate temperature state with almost uniform atmospheric temperature and which can be used for other purposes such as a dining table or a reception table when not heated.

In the home kotatsu of this invention, the kotatsu body is constructed by supporting the top plate above the bottom plate and only the central part of the bottom surface of the top plate with a single pillar, so that when entering the kotatsu or entering the kotatsu. In addition to keeping the pillars out of the way and making it possible to insert your feet from anywhere around the kotatsu (even from the corners), by laying an electric carpet on the top of the bottom plate, almost the entire inside of the kotatsu is covered. By making it possible to heat the kotatsu to a uniform and comfortable temperature, and by removing the electric carpet when not using it for heating, this home kotatsu also looks great when used for other purposes such as a dining table or reception table. It is characterized by the fact that it does not deteriorate.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The home kotatsu of the embodiment shown in FIGS.
The kotatsu main body 1 is supported by one support 6, and an electric carpet 2 is removably laid on the upper surface of the bottom plate 4.

The bottom plate 4 and the top plate 5 are formed into a substantially square shape with a predetermined area removed from each of the four corners of each of the plates 4 and 5. Note that the bottom plate 4 and the top plate 5 are formed to have approximately the same area.

The support column 6 is configured to be expandable and retractable by a metal expandable double tube (an upper tube 11 and a lower tube 12).
The upper end of the upper tube 11 and the lower end of the lower tube 12 of the strut 6 are provided with male threads 11a and 12a, respectively.

A threaded cylinder 14 is formed in the center of the bottom plate 4 and has a female thread engraved thereon that engages with a male thread 12a at the lower end of the lower strut tube 12.

A threaded cylinder 15 is formed in the center of the lower surface of the top plate 5 to be screwed into a male thread 11a at the upper end of the upper column tube 11. The top surface of the top plate 5 is finished with a rubber-based material to prevent the table stand from slipping when a table stand or the like is placed on top of the top plate 5.

The kotatsu main body 1 is assembled as follows. That is, first, the male thread 12a at the lower end of the lower column tube 12 is screwed into the screw tube 14 formed in the center of the bottom plate 4, and then the upper portion of the column is inserted into the screw tube 15 formed in the center of the lower surface of the top plate 5. The male screw 11a at the upper end of the tube 11 is screwed together, and then the lower end of the upper tube 11 is inserted into the upper opening of the lower tube 12 to a specified depth, and the upper tube 11 and the lower tube 12 are connected. The two tubes 11 and 12 are assembled by connecting and fixing them to each other by inserting a common pin 10 between them. The height of the top plate 5 can be adjusted by changing the overlapping length of the upper tube 11 and the lower tube 12. Further, an adjustment screw 17 is provided at a portion near the outer periphery of the bottom plate 4 to finely adjust the height so that the outer periphery of the bottom plate 4 touches the floor surface. I am trying to make minor adjustments to the height of 4.

The electric carpet 2 has an area that protrudes outward from each side (four sides) of the bottom plate 4 by a predetermined width. The parts of the electrical carpet 2 that protrude outward from each side of the bottom plate 4 (parts 2a) can be folded inward into two as shown by 2a' in FIG. 2B. The protruding portion 2a of the outer panel of the carpet 2 where people do not sit can also be folded inward.

This electric carpet 2 can be removed from the kotatsu body 1 during seasons when heating is not required. Incidentally, reference numeral 18 is an electric appliance plug of the electric carpet 2.

To explain an example of the use of the home kotatsu shown in FIG. 1A and FIG. It is used by covering it and further placing a ready-made kotatsu base plate 21 on top of it. In the usage example shown in Fig. 2A, when inserting your feet into the kotatsu, no matter where you insert them from any position on the outer circumference of the kotatsu body 1 (for example, from a corner), your feet will not hit any obstacles (posts). , it can be used in a relaxed state. Furthermore, since the pillars 6 are located in the center of the kotatsu body 1, the pillars 6 do not get in the way even when the user enters the kotatsu and lies down. Furthermore, since the electric carpet 2 heats the kotatsu almost uniformly from the entire lower part of the kotatsu, the entire inside of the kotatsu is heated to a comfortable temperature that is almost uniform. In addition, if you use electric carpet 2 for heating,
The entire inside of the kotatsu can be heated almost uniformly, resulting in better thermal efficiency than conventional infrared lamps.

In addition, when this home kotatsu is not used for heating, it can be used as a dining or reception table by placing a dining or reception table 22 on top of the top plate 5 as shown in FIG. It can also be used for other purposes. In this case, the table stand 22
It is preferable to fix it on the top plate 5 with a fastener 23 or the like. Furthermore, when this home kotatsu is used as a dining table or reception table, the appearance will not deteriorate if the electric carpet 2 is removed.

Next, to explain the effects of the present invention, the home kotatsu of the present invention has the following effects.

(1) Since the top plate 5 of the kotatsu body 1 is supported only at the center of its lower surface by a single post 6, the post 6 does not get in the way when you insert your feet into the kotatsu or when you enter the kotatsu. It can be used in a relaxed state. In particular, even when a large number of people use the kotatsu at the same time, such as when inserting their feet into the corner of the kotatsu, there is no problem of the pillars getting in the way, unlike the conventional four-legged home kotatsu.

(2) Since the electric carpet 2 is used as a heating heat source, the entire inside of the kotatsu can be heated to an almost uniform comfortable temperature, and unlike conventional infrared lamps, heating can be done at different locations within the kotatsu. This eliminates the problems of being too hot (located directly under the infrared lamp) or under-temperature (located on the outer periphery of the kotatsu).

(3) The electric carpet 2 is removable, so if you use this home kotatsu for other purposes other than heating (for example, when using it as a dining table or reception table), you can attach the electric carpet 2.
If you remove it, it won't look bad.
