Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an insecticidal device 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 systems, indoor rooms tend to be more tightly sealed, making it easier for tatami pests, especially mites, to infest the insides of tatami mats.

PRIOR ART Chemicals have traditionally been used to exterminate mites on tatami mats. However, even if the chemical is sprayed, its effect does not reach the inside of the tatami, and the condition cannot be maintained for a long period of time.
It has become almost impossible to completely exterminate ticks and other insects.

On the other hand, various experimental results show that heat can be used to exterminate pests, especially mites. This type of thermal extermination can be done by storing tatami mats inside a heating chamber.
By heating to a temperature of at least 65° C. or higher for a period of time, mites can be almost completely killed.

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 therein, and heating the tatami mats. However, since it is difficult to transport tatami mats in and out of high-rise residential buildings, there is a need for indoor heat-killing methods.

OBJECT OF THE INVENTION Therefore, an object of the present invention is to enable the extermination of tatami pests, especially mites, by heating easily indoors.

SUMMARY OF THE INVENTION Therefore, the present invention places a base plate approximately the same size as one tatami mat in a tatami room, leans a plurality of tatami mats on top of it in a non-contact state, and then It is covered with a heat-resistant cover, and hot air is blown into the inside by 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 devices for tatami mats are designed so that they can first raise one tatami mat indoors, then install it on that area, and store other surrounding tatami mats on the base plate. Therefore, such insecticidal work on tatami mats is carried out only inside the tatami room to be heated, so it can be carried out without any problem even in urban houses or densely populated residential areas.

1 to 3 show an insect killing device 1 for tatami mats according to the present invention.

This insect killing device 1 for tatami mats 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 by, for example, bending a pair of pipes into an inverted U-shape, and integrally includes a plurality of downward protrusions 6 on its upper horizontal portion. These protrusions 6 are formed with a pitch 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 removably fitted into vertical mounting holes 8 formed at the four corners of the base plate 3 at their lower ends. 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
They are provided facing each other on the short sides of the two, and are prevented from falling over by a support 9 which is stretched over the upper end portion as necessary.

The cover 4 is made of heat-resistant cloth or the like and is shaped like a tent-like bag. Connectors 10, such as open fasteners, are attached to the hem of the cover 4 and the outer periphery of the base plate 3.
attached by sewing or other means. Therefore, after the cover 4 is placed over the pair of support frames 2, it can be connected to the base plate 3 in a sealed manner by means of the hem connectors 10.

On the other hand, this cover 4 forms a hot air inlet 11 that widens toward the end on one side, and a flexible exhaust pipe 13 at the hot air outlet 12 on the other side.
is connected to. The hot air generator 5 is installed, for example, on a truck, and can be connected to the hot air intake 11 at the hot air outlet 14.

Effect of the Invention The above-mentioned tatami insect killing device 1 is used in the following method.

First, the insect killing device 1 for tatami mats is disassembled into each component and brought into a room with tatami mats to kill insects. Then, it is assembled into the state shown in FIG.

First, raise the tatami mat 7 in the center of the room, for example,
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 by the protrusions 6 so that they do not fall down.

Next, the support 9 is stretched between the pair of support frames 2, and then the cover 4 is placed on top of the support 9, and the hem part 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
wraps a plurality of tatami mats 7 in a sealed state to 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 pipe 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 heat the inside to about 100°C. 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, heats the inside of the tatami mats 7 to 65° C. or more, heats the inside of the tatami mats 7, and thermally completely kills pests, especially mites, inside. 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 heat and kill insects on most of the tatami mats 7.

After heating, the internal hot air is discharged from the hot air outlet 12 to the outside through the exhaust tube 13. 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, which automatically adjusts the temperature of the hot air. The sensor part of this temperature regulator is not limited to the inside of the hot air generator 5,
For example, it may be attached to the support frame 2 or to the inner ceiling of the cover 4.

In addition, if the tatami mat 7 to be heated is made of synthetic resin material, depending on the thermal characteristics of the material,
The heating temperature is set lower than that of regular tatami mats.

Other Embodiments 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-shaped one, and may be formed of a lattice-like frame, for example. It can also be configured. In that case, the cover 4 can also be configured as a complete hexahedron in order to close the lower part of the lattice-shaped base plate 3.

Further, the connecting device 10 is not limited to an open fastener, but may be constructed of a snap button, a hook, or other similar devices.

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 performed indoors. Therefore, the work of carrying in and out the tatami from the room can be omitted,
You can efficiently kill insects on tatami mats.

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 heating and insect killing efficiency of the tatami mats is improved.

Furthermore, since the tatami mat is wrapped by the base plate and cover during heating, and the hot air inside is exhausted to the outside, it is possible to prevent pests from remaining indoors.
