Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an insecticidal method and apparatus for exterminating tatami pests, particularly tatami mites.

Background of the Invention In today's residential environment, it is almost impossible to dry tatami mats naturally. Moreover, with the spread of air conditioning and heating equipment,
As indoor rooms tend to be more tightly sealed, tatami pests, especially mites, are more likely to infest the interior of tatami mats.

BACKGROUND ART Chemicals have traditionally been used to exterminate mites on tatami mats. However, even if a chemical is sprayed, its effect does not reach the inside of the tatami mat, and the condition cannot be maintained for a long period of time, making it almost impossible to completely exterminate dust mites. There is.

On the other hand, various experimental results show that heat can be used to exterminate pests, especially mites. Such thermal extermination can almost completely kill the mites by storing the tatami in a heating chamber and heating it to a temperature of at least 65° C. for a certain period of time.

However, such a heating chamber cannot be brought into a normal home, so it is almost impossible to kill insects by heating indoors.

On the other hand, it is possible to heat the tatami mats outdoors by providing a heating chamber in a car or the like, storing the tatami mats inside the chamber, and heating the tatami mats. However, in high-rise residential buildings, etc., it is difficult to bring in and take out tatami mats, so a heating method for killing insects indoors is desired.

OBJECT OF THE INVENTION Accordingly, an object of the present invention is to make it possible to easily exterminate tatami pests, especially mites, indoors by heating.

SUMMARY OF THE INVENTION Therefore, the present invention places a plywood board approximately the same size as a single tatami in a tatami room, leans multiple tatami mats on top of it in a non-contact manner, and then heats the tatami mats. It is covered with a plastic cover, and hot air is blown into the inside using a hot air generator. This hot air heats all the tatami mats inside the cover with uniform heat distribution, thermally killing pests, especially mites, inside the tatami mats before being discharged to the outside of the cover.

Such insecticidal methods and insecticidal devices specifically for tatami mats are made by first removing one tatami mat indoors, and then installing it on that area.
It is designed so that other surrounding tatami mats can be stored in plywood. Therefore, since this type of insecticidal work on tatami mats is carried out only inside the tatami room to be heated, it can be carried out without any problem even in urban houses or densely populated residential areas.

Structure of the Embodiment FIGS. 1 to 3 show a blue insecticidal device 1 of the present invention.

This blue insecticidal device 1 consists of a pair of support frames 2, a base plate 3, a cover 4, and a hot air generator 5.

The support frame 2 is formed, for example, by bending a pair of pipes into an inverted U-shape, and is provided with a plurality of downwardly directed protrusions 6 between them at the upper horizontal portion thereof. These protrusions 6 are formed with a pinch approximately equal to the thickness of the tatami mat 7, and are provided to hit the upper end of the tatami mat 7 in a leaning state and hold it in a state where it does not fall down.

The pair of support frames 2 are vertically attached to the 68 formed at the four corners of the base plate 3 at the lower end.
It is removably fitted. This base plate 3 has a rectangular shape that is approximately the same size as the tatami mat 7, and is formed to be slightly thicker than the tatami mat 7. In this way, the pair of support frames 2 are provided facing each other on the short sides of the base plate 3, and are prevented from falling over by the support frames 1-9 stretched over the upper end portions, if necessary.

Further, the cover 4 is formed into a tent-like bag shape from heat-resistant cloth or the like. A connector 10 such as an open fastener is attached to the hem portion of the cover 4 and the outer peripheral portion of the base plate 3 by sewing or other means. Therefore, cover 4
After being covered with the pair of support frames 2, the base plate 3 can be connected to the base plate 3 in a sealed state by means of the hem connector 10.

On the other hand, the cover 4 forms a hot air inlet 11 that widens toward the end on one side, and is connected to a flexible exhaust pipe 13 at the hot air outlet 12 on the other side. The hot air generator 5 is installed, for example, on a trolley, and the hot air intake is located at the hot air outlet 14.
It is now ready to connect to 1.

Effect of the Invention The above-mentioned tatami insect killing device 1 is used by the following method. First, this blue insect killing device 1 is disassembled into each component and brought into a tatami room where insects are to be killed. Then, it is assembled into the state shown in FIG.

First, for example, the tatami mat 7 in the center of the room is raised and the base plate 3 is installed in that part. Then, after attaching the pair of support frames 2 to the base plate 3 in a leaning state, in addition to the first tatami 7 raised, the surrounding tatami mats 7 are successively peeled off, and while being laid down on the base plate 3, It is placed in a leaning position. At this time, as shown in FIG. 2, all the tatami mats 7 are held in a non-contact state with each other and are held in a state that they do not fall down by the projections 6.

Next, the support 9 is stretched between the pair of support frames 2, and the cover 4 is placed over the top of the support frames 2, and the bottom portion of the cover 4 is fixed to the circumferential surface of the base plate 3 using the connector 10. In this way, the base plate 3 and the cover 4 hermetically enclose the plurality of tatami mats 7 and form a space inside. Then, the hot air outlet 14 of the hot air generator 5 is connected to the hot air intake 11, and the hot air exhaust tube 13 is led out of the hot air exhaust space, for example, the outside of the room.

After doing this, the hot air generator 5 is operated to send hot air into the space inside the cover 4 to raise the internal temperature to 100°C.
Heat to a moderate temperature. This state is maintained for, for example, 30 minutes or more and up to 2 hours. At this time, the hot air enters between the plurality of tatami mats 7 and heats the inside of the tatami mats 7 to 65°C or more, heating the inside of the tatami mats 7 and completely thermally killing the pests inside, especially the mites. . Since the tatami mats 7 are propped up in a non-contact state, the heat of the hot air is uniformly distributed to all the tatami mats 7. Therefore, it is possible to uniformly dry and heat insects to most of the tatami mats 7.

After heating, the internal hot air flows from the hot air outlet 12 to the exhaust pipe 13.
After that, it is discharged outside. If the exhaust resistance is large, an exhaust fan is interposed in the middle of the long exhaust pipe 13. This hot air generator 5 is equipped with an automatic temperature controller inside and automatically adjusts the temperature of the hot air. The sensor portion of this temperature regulator is not limited to the inside of the hot air generator 5, but may be attached to the support frame 2, or to the inner ceiling portion of the cover 4, for example.

Note that if the tatami mat 7 to be heated is made of a synthetic resin material, the temperature during heating is set to a temperature lower than that of a normal tatami mat, depending on the thermal characteristics of the material.

Modifications of the Invention In the embodiments described above, the bottom of the cover 4 is closed by the base plate 3, but the base plate 3 is not limited to a plate-like structure, but may also be constructed of a lattice-like frame, for example. In that case,
The cover 4 can also be constructed as a complete hexahedron in order to close the lower part of the lattice-shaped base plate 3.

Moreover, the above-mentioned connecting tool 10 is not limited to an open fastener.
It may also consist of snap buttons or hooks or other similar items.

Effects of the Invention In the present invention, since the heating device for killing insects on tatami mats is assembled inside the room, extermination of tatami pests and drying of tatami mats can be easily carried out indoors. This eliminates the need to bring in and take out tatami mats from the room, making it possible to kill insects on tatami mats more efficiently.

When heating the tatami mats, multiple tatami mats are supported by the support frame in a non-contact manner, so the heat is evenly distributed and the tatami heating and insect killing efficiency are improved.

Furthermore, since the tatami is wrapped in plywood and a cover during heating, and the hot air inside is exhausted to the outside, it is possible to prevent pests from remaining indoors.
