Description

[Detailed description of the invention] [Industrial application field] This invention relates to a deodorizing sheet for a kotatsu using a deodorizing agent.

[Conventional technology]

Conventionally, kotatsu have been widely used as a means of heating rooms in winter. There are kotatsu types with a heater attached to the back of the top plate of the yagura, as well as kotatsu types with a heater installed at the foot of the kotatsu, such as horigokotatsu, and in both cases, the yagura is used by covering it with a futon.

[Problem that the invention attempts to solve]

In conventional kotatsu, the interior is covered with a futon, so it is almost sealed, so when you put your feet inside to warm up, the smell of feet and other bad odors fills the room, making it unpleasant.

[Means for solving problems]

The deodorizing sheet for kotatsu of this invention consists of a heat-reflecting cover that is placed on the kotatsu tower and has a bag-like structure using a heat-reflecting material on at least the lower surface and has small holes in the lower surface, and this heat-reflecting cover. and a deodorizer housed inside.

[Effect]

According to this idea, the deodorizer is housed in a heat-reflecting cover that is placed on top of the kotatsu, and a small hole is drilled in the bottom of the heat-reflecting cover, so that the bad odor inside the kotatsu rises upward along with the warm air. It enters the heat reflective cover through the small hole and is deodorized by the deodorizing agent. Therefore, bad odors inside the kotatsu can be efficiently removed. Furthermore, by using the heat reflective cover, the thermal efficiency within the kotatsu can also be increased.

〔Example〕

An embodiment of this invention will be described based on FIGS. 1 to 4. FIG. 1 is a bottom view of the deodorizing sheet for a kotatsu according to this embodiment, and FIG. 2 is a cross-sectional view taken along the line -2.

As shown in FIGS. 1 and 2, the deodorizing sheet of this embodiment has a bag-shaped heat reflective cover 1 using two heat reflective materials 4, 4 made of thermoplastic resin sheets with aluminum vapor-deposited. At the same time, a deodorizer 3 is housed inside the heat reflective cover 1.

The heat reflective cover 1 is formed by overlapping the two heat reflective sheets 4, 4 and fixing the peripheral edges 1a together by heat fusion. As shown in FIG. 2, a plate-shaped elastic material 5 made of sponge or the like is housed inside the heat reflective cover 1, and the deodorizer 3 is housed in a notch 6 provided in the elastic material 5. Ru. The notch 6 is formed at a position corresponding to the small hole 2 partially provided in the heat reflecting material 4 on the lower surface. Therefore, when the deodorizing agent 3 is accommodated in the notch 6, the deodorizing agent 3 will be located above the small hole 2.

The heat reflective cover 1 containing the deodorizer 3 in this manner is placed on the kotatsu tower. FIG. 3 shows the state in which the deodorizing sheet according to this example is used. As shown in Figure 3, the heat reflective cover 1
It has almost the same dimensions as the top plate of Hayagura 7, and covers the top plate. And this heat reflective cover 1
Futon 8 is placed on top of . The top plate of the tower 7 is formed in a lattice shape, such as a parallel grid, supported by legs 9 at the four corners, and a heater 10 is installed on the lower surface of the center.
will be installed. Therefore, the small hole 2 formed on the lower surface of the heat reflective cover 1 needs to be formed in a position where it will not be blocked by the legs 9 or the heater 10.
In this embodiment, as shown in FIG. 1, small holes 2 are formed at four locations slightly inward from the four corners of the heat reflective cover 1. However, if the heater 10 is not installed on the lower surface of the top plate of the tower 7 (for example, a sunken kotatsu), it goes without saying that a small hole may be provided in the center.

With this structure, when the kotatsu is in use, unpleasant odors such as foot odor that remain inside the kotatsu rise upward along with the warm air inside the kotatsu, and the heat reflective cover 1
It enters the heat reflective cover 1 through the small hole 2 provided on the lower surface of the deodorizer 3 and is captured by the deodorizer 3. Moreover, since the heat reflective cover 1 is made of the heat reflective material 4, it is convenient for reflecting the warm air rising upward and increasing the thermal efficiency within the kotatsu.

The deodorizer 3 is made of two breathable sheets 11, 11 made of paper, nonwoven fabric, etc., as shown in FIG. 4A.
A bag 12 formed by fixing the periphery of the container is filled.
In this case, it is preferable to temporarily fix the bag 12 within the notch 6 with adhesive tape or the like (not shown) so that the bag 12 does not move within the heat reflective cover 1 . As the deodorizing agent 3, in addition to the conventionally used activated carbon, powdery or granular ones such as "Daimushyu" manufactured by Dainichiseika Kagyo Co., Ltd. can be used. Since these deodorizers 3 usually need to be replaced after use for February to March, the periphery of the heat reflective cover 1 has a structure that can be partially opened and closed (for example, a chuck mechanism).
It is preferable that

In addition, if the deodorizer 3 does not need to be replaced, as shown in FIG. The fused bag body 15 is filled with the air permeable sheet 11.
The bag body 15 is thermally fused to the edge of the notch 6 of the heat reflective material 4 or the elastic material 5 using a thermoplastic resin sheet 13 that is longer than the above, so that the deodorizer 3 is completely prevented from moving. You can.

In this embodiment, the heat reflective material 4 is used on both sides of the heat reflective cover 1, but the heat reflective material 4 may be used only on at least the bottom surface.

[Effect of idea]

According to this idea, the deodorizer is stored inside the heat-reflecting cover with small holes drilled in the bottom surface and is placed on top of the kotatsu tower. can be removed efficiently. In addition, the heat-reflecting cover reflects heat rays and increases the heat efficiency inside the kotatsu.

The deodorizer is housed inside the heat-reflecting cover, so it does not come into direct contact with the human body and cause discomfort, and it does not get in the way when you put your hands or feet inside the kotatsu.
