Description

[Detailed description of the invention] [Technical field] This invention relates to a horigotatsu whose main body is installed under the floor.

[Background technology]

Traditionally, hori-kotatsu (hori-kotatsu), which has a main body under the floor and a heater box at the bottom, have been widely used.

In the winter, such a horigotatsu is used for heating by placing a futon or the like over a low table placed on the top and placing a top plate on top of it, using the heat source of a heater box placed at the bottom.

Then, in the summer, you can store the low table under the floor and hide the top opening of the horigotatsu body with tatami mats, etc.
Alternatively, the futon is removed and the heat source is turned off, but in either case, the interior of the unit under the floor is sealed and the cold air from under the floor cannot be used effectively.

[Purpose of invention]

The purpose of this invention is to provide a horigotatsu that can effectively utilize the cool air from under the floor during the summer.

[Disclosure of invention]

The Horigotatsu of this invention is equipped with a main body that is installed under the floor and has an opening in the wall, and a mutually replaceable heat insulation panel and ventilation panel that are detachably attached to the opening of the main body.

In this way, according to this invention, a heat insulating panel or a ventilation panel is removably attached to the opening in the wall of the main body, and the heat insulating panel and ventilation panel are configured to be interchangeable. By attaching an insulating panel to the bottom and installing a heater box at the bottom, it can be used for heating as usual. On the other hand, in the summer, the insulation panel can be removed and a ventilation panel installed in the opening, allowing cool air from under the floor to be taken in. This allows you to cool your feet by putting your feet inside the main body, and further helps to reduce the temperature inside the room.

Embodiment An embodiment of this invention will be explained based on FIGS. 1 to 4. In other words, as shown in Figure 1, this Horigotatsu is placed under the floor and has two openings on the wall.
The main body 1 is provided with a main body 1, and a heat insulating panel 3 and a ventilation panel 4 which are removably attached to an opening 2 of the main body 1 and are mutually replaceable.

As shown in FIG. 1, the main body 1 is made of a heat insulating material, and has a top plate 6 on its upper surface.
A heater box (not shown) serving as a heat source is arranged at the bottom of the low table 5 on which the table 5 is placed. Further, 7 is a stile provided in the opening of the floor 8. Furthermore, a large opening 2 is provided in the peripheral wall 9 of the main body 1.
A heat insulating panel 3 or a ventilation panel 4 is removably attached to the opening 2 as shown in FIGS. 2 and 3, and the heat insulating panel 3 and ventilation panel 4 are
and are configured to be interchangeable.

As shown in FIG. 2, the heat insulating panel 3 is a panel with high heat insulating properties, and is fixed to the periphery of the opening on the outer surface of the main body 1 with wood screws 15 or the like, and is attached to a mounting plate 10 protruding into the opening by fasteners 11. Fixed.
The fixing tool 11 is a butterfly screw having a butterfly-shaped head 11a, and is inserted into a screw insertion hole 19 provided in the heat insulation panel 3 and screwed into a screw hole 10a provided in the mounting plate 10 to attach the heat insulation panel 3. It is fixed to the plate 10.
Furthermore, a cap 16 is fitted into the entrance of the screw insertion hole 19 on the inner surface of the heat insulating panel 3, and the mounting plate 1
A packing 18 is interposed between 0 and the heat insulating panel 3. Further, a decorative frame 14 having a T-shaped cross section is attached to the periphery of the inner surface of the heat insulating panel 3 to hide the gap between the main body 1 and the insulating panel 3. A packing 17 is interposed between the main body 1 and the decorative frame 14.

As shown in FIGS. 3 and 4, the ventilation panel 4 includes a frame 13 having a screw insertion hole 19, and a plurality of vertical elliptical shapes arranged in the frame 13 to face each other and correspond to each other. It is formed from a movable plate 12b having ventilation holes 20, 21 and a fixed plate 12a. The movable plate 12b is slidably held within rails 12c that protrude above and below a fixed plate 12a fixed within the frame 13. The size of the ventilation opening 20 of the fixed plate 12a can be adjusted by adjusting the slide of the movable plate 12b.

The method for attaching the ventilation panel 4 to the main body 1 is exactly the same as that for attaching the heat insulation panel 3, so the same components as shown in FIG. do.

In this way, the heat insulating panel 3 or the ventilation panel 4 is removably attached to the opening 2 provided in the peripheral wall 9 of the main body 1, and the heat insulating panel 3 and the ventilation panel 4 are configured to be interchangeable. is attached to perform heating as before, and in summer, the insulation panel 3 is removed and a ventilation panel 4 is attached, allowing cold air from under the floor to be taken into the room. Also,
Since the ventilation panel 4 has adjustable ventilation openings, appropriate ventilation can be adjusted.

Note that the size of the opening 2 in the wall surface of the main body 1 is not particularly determined, and the opening 2 may be provided at the bottom, or may be provided in a part of the wall surface without being provided in the entirety.

[Effect of idea]

According to the Horigotatsu of this invention, a heat insulating panel or a ventilation panel is removably attached to the opening provided in the wall of the main body, and the heat insulating panel and the ventilation panel are configured to be interchangeable. By attaching a heat insulating panel to the opening and installing a heater box at the bottom, it can be used for heating as usual. On the other hand, in the summer, the insulation panel can be removed and a ventilation panel installed in the opening to let in the cool air from under the floor, allowing the user to put their feet inside the unit to cool their feet and further reduce the temperature inside the room. effective.
