Description

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

A sunken kotatsu with slats 3 installed in a hearth box 1 has conventionally been formed as shown in FIG. 7.

That is, in this case, the heater storage recess 20 is provided in the center of the lower surface of the furnace box 1, and the slats 3 are placed on the slat mounting surface 5 formed on the bottom surface of the furnace box 1 at the opening periphery of the heater storage recess 20. The periphery of the

However, in this case, the height of the slat 3 is constant when it is placed on the slat mounting surface 5, so families with many children or families without children can place the slat 3 in a kotatsu. When placing one's feet on the kotatsu, there is a problem in that the slats 3 are either too low or too high, resulting in poor posture when entering the kotatsu.

Furthermore, as mentioned above, since the peripheral edge of the slat 3 is placed directly on the slat mounting surface 5, there is no gap between the lower surface of the slat 3 and the slat mounting surface 5 over the entire circumference. The hot air from the heater 6 in the heater storage recess 20 mainly passes through the perforated plate 15 of the drainboard 3 and rises above the drainboard 3.
Hot air cannot rise from the periphery of the grates 3 along the inner wall of the furnace box 1, and the hot air cannot directly act on the legs placed on the periphery of the grates 3, Heating efficiency was not very good.

The present invention was developed in view of the above points, and allows the height of the slats in the hearth box to be easily changed according to the family structure, allowing the user to enter the horigotatsu in a comfortable position. Moreover, it is an object of the present invention to provide a sunken kotatsu which can raise the hot air in the heater storage recess from the periphery of the grates and can sufficiently circulate the hot air around the feet.

That is, the present invention has a furnace box 1 installed under the floor with an opening on the top surface, a heater storage recess 20 in which the heater 6 is stored in the center of the bottom surface, and a heater storage recess 20 that is curved downward. The bottom surface of the box 1 is used as a slat mounting surface 5, and a plurality of recessed fitting parts 2 are provided in the slat mounting surface 5.
A plurality of slatted legs 4 are provided on the lower surface of the slatted slat 3 arranged inside, and when the slatted slatted 3 is placed in the furnace box 1 in a predetermined direction, each slatted leg 4 and each recessed fitting part 2 correspond vertically. When the slatted slatted foot 4 is placed on the slatted slat mounting surface 5 and the slatted slatted foot 3 is turned horizontally by 90° or 180° from this state, the slatted slatted foot 4 and each recessed fitting portion 2 are moved upward and downward, respectively. By setting the arrangement relationship between the slatted legs 4 and the recessed fitting parts 2 so that all the slatted legs 4 are fitted into each recessed fitting part 2 correspondingly, and drilling the predetermined position, the recessed fitting parts 2 and the slatted legs 4 are set. This is the positional relationship between the slat feet 4 placed on the slat mounting surface 5 and the slat feet 4
The above object is achieved by allowing the grates to be placed in the furnace box 1 in any state in which the grates are inserted and fitted into the recessed fitting portions 2.

The present invention will be explained in detail below using examples.

FIGS. 1 and 2 show a first embodiment, in which a furnace box 1 with an open top is made of synthetic resin and has a uniform thickness, and the center of the bottom is concavely curved as a heater storage recess 20. A heater 6 and a heater box 7 made of a galvanized iron plate are stored in the heater storage recess 20.

A recessed fitting part 2 is formed on the slat mounting surface 5 around the heater storage recess 20 of the furnace box 1 by concavely bending the bottom surface of the furnace box 1.

The recessed fitting part 2 is made up of four recessed grooves 21, and by forming the recessed grooves 21 with a concave curve on the bottom surface of the furnace box 1, the furnace box 1 can be reinforced by the rib effect of this recessed curve.

Each of the grooves 21 is formed in parallel, and the width of each groove is medium.

The furnace box 1 thus formed is attached to a notch between the joists 9 and the floor plate 10 between the large drawers 8 and 8 using the locking flange piece 11 at the upper end.

12 is a stile placed on the locking collar piece 11, and 13 is a tatami mat.

The grates 3 are formed by attaching grates 4 to the lower surface of a large number of parallel grates 14, and the grates 3 are formed in a square shape, with a perforated plate 15 made of a flocked metal plate in the center. It is.

In addition, the slatted legs 4 are installed non-parallelly at positions corresponding to the four grooves 2 on the bottom of the furnace box 1, and the width of the slatted legs 4 is sandwiched between the groove widths of the grooves 21. The length of the groove 21 is longer than the width of the groove 21.

This drainboard 3 is formed to be slightly smaller than the inner circumference of the furnace box 1, and when installing the drainboard 3 in the furnace box 1, first position the drainboard feet 4 parallel to the grooves 21, and then place the drainboard 3 inside the furnace box 1. When placed on the slat mounting surface 5, the slat feet 4 are completely recessed into the recessed grooves 21 as shown in FIG.

Also, rotate this drainboard 3 by 90 degrees on the horizontal plane, and
When the slat 3 is placed in the furnace box 1 with the slat 3 placed perpendicular to the groove 21, the slat foot 4 is stably placed on the slat mounting surface 5 at the upper surface position of the groove 21 as shown in FIG. This means that the gridiron 3 can be installed at a higher position than the bottom surface of the furnace box 1.

FIG. 3 shows a second embodiment, and FIGS. 3a and 3l) are a plan view of the furnace box 1 and a side view of the slat 3, respectively.
are formed on the bottom surface of the furnace box 1 so as to be parallel but asymmetrical with respect to the longitudinal centerline l, and the slatted legs 4 are attached parallel to the positions corresponding to the grooves 21.

Therefore, if the grates 4 are inserted into the grooves 21, the grates 3 can be installed at a lower position, and if the grates 3 are rotated 90 degrees on the horizontal plane, the grooves 21 will be perpendicular to the grates 4, so the upper surface of the grooves 21 will be positioned. If it is placed in the groove 2 and rotated 180 degrees,
1 is formed asymmetrically, so the concave groove 21 and the slatted foot 4 are
The slatted legs 4 are placed on the slatted slat mounting surface 5 so that the slatted slats do not fit into each other even if they are parallel to the slatted slats 3, and the slatted slats 3 can be installed at a higher position than the bottom surface of the furnace box 1.

FIG. 4 shows a third embodiment, and FIG. 4 a and l) are a plan view of the furnace box 1 and a side view of the slat 3, and
A recess 22 is formed as a recess fitting part 2 on the bottom surface of the slat 3 at a point asymmetrical position with respect to the center point P, and the slatted foot 4 is attached to the slat 3 at a position corresponding to and fitting with the recess 22.

Therefore, by fitting the slatted legs 4 into the recesses 22, the slats 3 can be installed at a lower position, and by rotating the slats 3 by 90° or 180°, the recesses 22 are formed asymmetrically, so that the recesses 22 and slats can be placed in a lower position. The slat mounting surface 5 does not fit with the legs 4.
The slatted legs 4 are placed on top, and the slatted slats 3 can be installed at a higher position than the bottom surface of the furnace box 1.

In any of the above embodiments, the slatted legs 4 are arranged so as to form a sufficient fulcrum so that when the slatted slat 3 is placed on the slatted slat mounting surface 5, it is placed stably without wobbling. It is.

FIGS. 5 to 6 show a fourth embodiment, in which two opposite sides of the grating mounting surface 5 around the heater storage recess 20 of the furnace box 1 are shown.
The sides are recessed to form a recessed fitting part 2, and a pair of slat feet 4 are attached between the lower surfaces of both ends of a large number of parallel slat boards 14 to form a slat 3.

However, if both ends of the slatted legs 4 are fitted into the recessed fitting parts 2 using levers, the slatted slats 3 can be installed at a lower position. If it is placed on the slat mounting surface 5, the slat 3 can be installed at a higher position than above.

In this case, both ends of the slatted board 14 located at both ends of the slatted foot 4 of the slatted board 14 are cut off to form cutout portions 30, and 31 is a convex rib on the bottom surface of the furnace box 1.

Returning again to FIGS. 1 and 2, 16 is a tower, formed by standing legs 19 between a top plate 17 and a middle stile 18.
It is installed on the furnace box 1 by arranging the middle stile 19 on the inner periphery of the stile 12.

The height between the upper surface of the top plate 17 of the tower 16 and the lower surface of the middle stile 18 is the upper surface of the slat board 14 when it is recessed into the groove 21 of the slat foot 4 and the slat 3 on the bottom of the furnace box 1 is installed as shown in FIG. The dimensions are set to be the same as the height between the upper end of the furnace box 1, and when storing the tower 16 when it is not in use, such as in the summer, the slats 3 are installed on the furnace box 1 as shown in Figure 1, and the stile 12 is removed. After that, when the tower 16 is housed in the hearth box 1, the height of the top plate 17 will match the height of the top of the hearth box 1, and the floor plate 1
The lower surface of the tatami mat 13 on 0 and the upper surface of the top plate 17 are on the same surface,
This means that the tatami can be laid on the top plate 17 flush with the tatami 13 on the floorboard 10.

In this way, the slatted legs 4 are inserted into the grooves 2 of the furnace box 1, preventing lateral movement, and the tower 16 can be placed on the slats 3 stored in the furnace box 1 in a stable state, resulting in a stable state. It will be possible to store Teyagura 16.

Of course, the height between the upper surface of the top plate 17 of the tower 16 and the lower surface of the middle stile 18 is adjusted by placing the grating feet 4 on the grating mounting surface 5 at the upper surface position of the groove 21, and adjusting the height between the bottom surface of the furnace box 1 as shown in FIG. The height may be set to be the same as the height between the upper surface of the slat plate 14 and the upper end of the furnace box 1 when the slat 3 is placed at a higher position.

Incidentally, the side peripheral wall of the furnace box 1 is slightly expanded upwardly so that the drainboard 3 can be easily pulled out upwardly.

As described above, in the present invention, a plurality of recessed fitting portions are provided in the slat mounting surface of the furnace box at the opening periphery of the heater storage recess, and a plurality of recessed fitting portions are provided on the lower surface of the slats disposed inside the furnace box. When the slat feet are provided and the slats are placed in the furnace box in a predetermined direction, each slat foot and each recessed part do not correspond vertically, and the slat feet are placed on the slat mounting surface, and When the slats are rotated from this state by 90' or 180° horizontally, each slat foot and each recessed fitting part correspond vertically, and the slatted legs are recessed so that all the slatted legs are fitted into each recessed fitting part. Now that we have set the positional relationship with the fitting part, we can choose between three conditions: the slatted foot can be fitted into the recessed part simply by horizontally rotating the slatted part, or the slatted foot cannot be fitted into the recessed part. can be installed in the furnace box, and there are two positions: a low position where the slatted foot is inserted into the recessed fitting part, and a high position where the slatted foot is not inserted into the recessed fitting part and the slatted foot is placed on the slatted surface. Two sets of high and low slats can be installed inside the furnace box, and the height of the slats can be adjusted to suit the family structure, such as raising the slats for families with many children and lowering the slats for families without children. By adjusting the height of the slats to a height suitable for placing one's feet, one can enter the horigotatsu in a comfortable position.

In addition, if the slats are installed in the furnace box so that the slatted feet are placed on the slatted surface, the bottom surface of the slatted slats will not be placed directly on the slatted surface. A gap corresponding to the thickness of the slat foot is formed between the lower surface of the slat periphery and the slat mounting surface in the part,
Through this gap, the hot air in the heater storage recess below the slats can be drawn out above the slats, and the hot air can be circulated around the slats above the slats. It is something that can be heated.
