CONSTITUTION:The sunken frame 13 having a depth B is arranged within a concave section 12 provided in the floor surface 11. The depth B of the sunken frame 13 is about 250-300mm. which is somewhat shorter than the length of one's legs. Numeral 14 designated the strut arranged at nearly the center of the bottom surface of the sunken frame 13 and a heater 15 is arranged within the strut 14. Numeral 16 designates the ceiling plate placed on the strut 14 and the size of the ceiling plate is made a little smaller than that of the opening 17 of the sunken frame 13 with the periphery of the ceiling plate lying inwardly of the periphery of the opening 17. As the depth of the sunken frame 13 is made to be 250-300mm., one can feel very easy with the foot warmer because he can put the soles of his feet to the bottom surface of the sunken frame 13 even when he stretches his legs within the sunken frame 13 while he sits on the floor surface 11. Further, as the ceiling plate 16 is made smaller than the opening of the sunken frame 13, one's kees do not come into contact with the ceiling plate 16 even if one is of large build.

However, in the conventional Horikotatsu with such a configuration, the legs 6 of the tower 5 get in the way and are inconvenient to enter and exit.
It was also very troublesome to clean the inside of the board frame 3. Furthermore, board frame 3
The depth is 360 to 400 mm, and when you sit on the floor 1 and put your feet into the board frame 3 in the recess 2, the soles of your feet will reach the bottom of the board frame 3.

It is equipped with a board frame of 00zyx, a support placed on the bottom of the board frame and equipped with a heating device, and a top plate placed on the support and smaller than the opening of the horisuite, and has the legs of a conventional tower. can be eliminated.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 11 is a floor surface, and 12 is a recess provided in this floor surface 11 into which a plate frame 13 having a depth dimension B is recessed. This dimension B is slightly shorter than the length of the human shin, and is approximately 250 to 300 mm. Reference numeral 14 denotes a support post disposed approximately at the center of the bottom of the plate frame 13, and a heating device 15 is provided inside thereof. Reference numeral 16 denotes a top plate placed on the pillar 14, and its size is slightly smaller inward than the periphery of the opening 17 of the plate frame 13.

In this way, since the depth of the board frame 13 is set to 250 to 300 mm, even if you extend your legs within the board frame 13 while sitting on the floor 11, you can easily touch the soles of your feet on the bottom of the board frame 13. It's easy. In addition, since the top plate 16 is made smaller than the opening 17 of the board frame 13, even if a large person sits down, his or her knees will not hit the top board 16, as shown in FIG. The inside is very easy to clean, coupled with the removal of the legs.

As described in detail, the present invention involves placing a support within a shallow board frame, and placing a top board smaller than the opening of the hole on top of the support, which allows the user to take a comfortable posture within the board frame. can.
