Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sunken kotatsu, and particularly relates to an improvement in one in which a heater is attached to the bottom of the hearth box.

(Conventional technology) Conventional horigotatsu had a heating box installed in a position dug into the bottom of the hearth box attached to the floor opening, but in recent years, with the development of thin heaters, flat hearth boxes have been installed. A heater is mounted on the bottom of the furnace box, and the overall depth of the furnace box is reduced.

In this case, since the heater is placed on the bottom of the furnace box so as to protrude upward, a footrest is provided at a predetermined distance from the bottom of the furnace box to prevent feet from directly touching the heater. At the same time, the slats are used as a footrest to make it more comfortable to sit on.

(Problem that the invention aims to solve) However, when the horigotatsu is not in use and the turret is stored inside the hearth box, the top of the yagura will be raised from the hearth box due to the relationship between the position of the drainboards in the hearth box and the height of the turret. It sticks out upwards, making it impossible to draw tatami on the hearth box. For this reason, the turret is disassembled and stored in the furnace box, but there are problems in that the storage operation is complicated and damage is likely to occur at the assembly joints. In addition, if the slats are removed and the turret is placed directly on the bottom of the furnace box for storage, the heater head will be placed at the bottom of the turret because the heater protrudes upward from the bottom of the furnace box by the thickness of the heater. The heater sticks out, and the heater gets in the way of storing parts and accessories such as frames inside the furnace box. Therefore, there is a problem in that a separate mounting member is required above the heater to prevent loads and shocks from being applied to the heater, resulting in increased costs.

The present invention was made in view of the above points, and its purpose is to easily and completely store the tower etc. in the furnace box without disassembling the tower, etc., and to store parts such as the stile. To provide a sunken kotatsu whose heater is not damaged when stored.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention includes a furnace box installed in the floor opening and having a flat bottom, and a furnace box installed in the center of the bottom. a heater, a grating body disposed at a predetermined distance from the bottom of the furnace box and supported by a support member, a stile disposed at the upper peripheral edge of the furnace box, and a stile installed on the furnace box. In the horigotatsu, the supporting member has a width equal to or greater than the height of the heater minus the thickness of the lower frame of the turret. It is attached to the bottom so that it can be rolled over, and the depth of the furnace box is set to match the sum of the height of the turret, the thickness of the slatted body, and the width of the support member. .

(Function) With the above configuration, in the present invention, the support member that supports the slatted body is attached to the furnace box so that it can be rolled over, so when the horigotatsu is not in use, the support member can be rolled over to make the turret. By moving the mounting position downward in parallel, the storage space within the furnace box is expanded, and the tower can be easily stored within the furnace box. Also,
The width of the supporting member is set to be equal to or greater than the value obtained by subtracting the thickness of the bottom frame of the turret from the height of the heater, and the depth of the furnace box is the sum of the turret height, the thickness of the slatted body, and the width of the supporting member. Since they are set to match, if you draw tatami on the hearth box with the turret stored inside the hearth box,
This tatami is supported by the turret and is flush with other tatami placed around the area where the horigotatsu is installed.
Furthermore, since the heater does not protrude into the lower part of the turret when the turret is stored, it will not be damaged by stored parts such as frames, and will not get in the way of storage.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 shows a sunken kotatsu A according to an embodiment of the present invention, in which 1 is a rectangular parallelepiped box-shaped hearth box attached to a floor opening having a rectangular planar shape. A stile 2 made of four stile members arranged in a rectangular shape is placed on the upper edge of the hearth box 1 so as to be flush with the tatami 3.
plays the role of an opening frame.

Further, the lower frame 6 of the turret 5 is locked to the turret locking tool 4 that protrudes inward from the side surface of the stile 2, and the furnace box 1
A tower 5 is installed on top. The turret 5 has an upper end,
It is composed of an upper frame 7 and a lower frame 6 each having a rectangular frame structure arranged at the lower end thereof, and leg parts 8, 8, . There is.

At a predetermined distance from the bottom 1a of the furnace box 1, there are support members 10, 10 extending in the front-rear direction that stand on the upper surface of the bottom 1a on both left and right sides in FIG. It is supported by and placed in a horizontal position. The support member 10 is
As shown in enlarged detail in Fig. 2, it has a generally rectangular cross section, and the inside of the lower part is cut out in an arc shape to make it easier to roll over. It is installed so that it can be rolled over in the direction of the arrow in the figure. Reference numeral 12 is a crosspiece to which each of the drainboard members is attached at regular intervals, and the crosspiece 12 also serves as a stopper for preventing the support member 10 from rolling over. Here, the depth h of the furnace box 1 is
is provided so as to match the sum (a+b+c) of the width a of the support member 10, the height b of the turret 5, and the thickness c of the slatted body 9.

The thickness c of the drainboard body 9 is the distance from the upper surface of the drainboard member to the lower surface of the crosspiece, and when a stopper for preventing the support member 10 from overturning is separately attached, it is the distance to the lower surface thereof. Reference numeral 13 denotes a thin heater placed below the grate body 9 and on the upper surface of the bottom 1a of the furnace box 1.

Next, to explain the functions and effects of the above embodiment,
As shown in FIG. 3, when the horigotatsu A is not in use and the turret 5, etc. is to be stored, first lift the slatted body 9 upward and remove it, thereby disengaging the connection between the crosspiece 12 and the supporting member 10. Remove the support members 10, 1
0 inward (in the direction of the arrow in the figure). Then, the turret 5 is placed on the overturned support members 10, 10, and the stile 2 is removed, and the turret 5 is placed diagonally on the lower frame 6 of the turret 5, and then stored. Furthermore, the drainboard bodies 9 are sequentially placed on the tower 5. By such a procedure, the tower, the saw, etc. can be easily stored in the furnace box 1 without disassembling them.

Moreover, in this case, the depth h of the furnace box 1 corresponds to the sum (a+b+c) of the width a of the support member 10, the height b of the turret 5, and the thickness c of the slat body 9.
The upper surface of the slatted body 9 on the tower 5 housed in the furnace box 1 is at the upper end height position of the furnace box 1. For this reason, furnace box 1
When the tatami mat 14 is placed on top, the tatami mat 14 is supported by the slatted body 9 or the turret 5 without using any size adjustment member, and the other tatami mats 3 around the place where the horigotatsu A is installed.
This makes it possible to simplify the storage operation.

Furthermore, when the turret 5 etc. are stored in the furnace box 1, the heater 13 does not protrude above the lower frame 6 of the turret 5, so it does not get in the way of storage, and when stored, The heater 13 will not be damaged by parts such as the frame 2.

In addition, as shown in FIG. 4, the height b of the tower 5 is
If the distance s from the upper end of the slat body 9 to the upper end of the stile 2 is the same, by placing the turret 5 on the slat body 9, the turret 5 can be moved without locking the upper frame 7 to the turret locking tool 4. It can be stored flush with Tatami 3. In addition, when the height b of the turret 5 is set to be less than the distance s from the upper end of the slat body 9 to the upper end of the stile 2, the turret 5 can be folded by locking the upper frame 7 of the turret 5 to the turret locking tool 4. Therefore, the horigotatsu A can be stored in accordance with the height of the turret, the dimensions and shape of the turret locking tool 4, and the turret upper frame 7.

In the above embodiment, the height of the heater 13 is equal to or less than the width a of the support member 10; If it is less than the total thickness of the frame 2
It goes without saying that it is possible to store items such as the above, and to achieve the same functions and effects as those of the above embodiments.

(Effects of the invention) As described above, according to the invention, the support member that supports the footrest grates in the furnace box is attached to the furnace box or the grates so as to be able to roll horizontally, and the width of the support member is set at the height of the heater. Since it is set to be equal to or less than the value obtained by subtracting the thickness of the bottom frame of the turret, and the sum of the width of the support member, the height of the turret, and the thickness of the slats matches the depth of the hearth box, there is no problem with the horigotatsu. When in use, by turning the support member sideways, the tower, slats, etc. can be easily stored inside the furnace box without disassembling it, and tatami mats can be dug on top of the furnace box without using any dimension adjustment members. It can be pulled flush with the tatami around the tatami area. Also, since the heater is protected by the support member,
Parts such as frames can be stored well without damaging the heater.
