Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a special vehicle for drying tatami mats while applying appropriate heat to exterminate tatami pests.

Background of the invention In today's residential environment, it is almost impossible to dry tatami mats naturally. Moreover, with the spread of heating devices, it has become easy for tatami pests, especially mites, to infest the inside of tatami mats.

PRIOR ART Chemicals have traditionally been used to exterminate mites on tatami mats. However, even if the drug is sprayed, its effect cannot be maintained for a long time.
In addition, it is difficult for the effect to reach the inside of the tatami mat, making it almost impossible to completely exterminate dust mites and the like.

Purpose of the invention and means of solution Therefore, the purpose of the invention is to thermally exterminate tatami pests, especially mites, in consideration of the above-mentioned circumstances.
Furthermore, it is desirable to be able to carry out thermal extermination in a mobile manner.

Therefore, the present invention installs a drying chamber on the car body, holds a large number of tatami mats in a non-contact state with a tatami support frame in this drying chamber, and dries them with hot air while airtight. During the drying process, heat is used to efficiently exterminate pests, especially mites, inside the tatami in a single hour.

Configuration of the Embodiment FIGS. 1 and 2 show a tatami drying car 1 according to the present invention. This tatami drying car 1 is equipped with a drying chamber 3 in a car body 2. This drying chamber 3 is equipped with, for example, a double-opening door 4 on the back side.
Further, it is connected to a hot air generator 7 such as a burner through a duct 6 of a hot air intake 5 at the lower front side of the vehicle body 2. This hot air generator 7 is installed on the vehicle body 2 similarly to the drying chamber 3, and can be operated from the outside. Note that this drying room 3 is
It communicates with the outside air through a hot air suction duct 8 and an exhaust duct 9 provided in the ceiling.

The tatami drying car 1 also includes a tatami support frame 10 made of a metal pipe inside the drying chamber 3. This tatami support frame 10 is composed of a plurality of leg frames 11, a plurality of partition frames 12 provided between these leg frames, and a plurality of receiving shafts 13 provided below these.

The leg frame 11 is formed of stainless steel pipe or the like into an approximately inverted U shape, and has a wheel 14 at one lower end, and a mounting plate 15 at the other lower end. There is. Further, the partition frames 12 have almost the same shape as the leg frames 11, are provided at appropriate intervals between the leg frames 11, and are arranged between the tatami mats 20.
It divides the space to support the. Further, the receiving shaft 13 is fixed in a state where it is stretched over the lower crosspiece 18 below the leg frame 11 and the partition frame 12, and between the leg frame 11 and the partition frame 12, and between the two adjacent For example, two or one roller 16 is rotatably supported in each space divided between the partition frames 12. Note that the leg frame 11 and the partition frame 12 are reinforced at one end by upper and lower horizontal bars 17 so as not to fall. Among these, the upper horizontal rail 17 also serves as a stopper for the tatami.

The tatami support frame 10 is removably attached inside the drying chamber 3. At the time of this installation, the wheels 14 move along the guide rails 19 provided at both ends of the drying chamber 3.
is pushed inside through the opening. In this process, since the guide rail 19 restricts the movement of the tatami support frame 10 in the width direction, the tatami support frame 10 moves to a predetermined position while being regulated to a predetermined position inside the drying chamber 3. . In this state, the mounting plate 15 is attached to the bottom surface of the drying chamber 3 by means such as screws.

Effects of the Invention The tatami drying vehicle 1 of the present invention can be moved close to the tatami mats 20 to be dried by its operation. Therefore, the drying chamber 3 is opened by the opening/closing door 4, and a plurality of tatami mats 20 are stored in the tatami support frame 10 inside the drying chamber 20, leaning against each other and not in contact with each other, as shown in FIG. I will do it. At the time of storage, the tatami 20 rides on the rollers 16 and is pushed into the tatami support frame 10 while rolling on the rollers 16, so the tatami 20 can be stored outside the car with a small force.
Moreover, it can be done efficiently. In this way, the tatami mats 20 to be dried are not in contact with each other.
It is stored inside the tatami support frame 10.

In this state, the door 4 is closed to seal the drying chamber 3, and then the hot air generator 7 is activated to heat the inside of the drying chamber 3 to approximately 100 degrees with hot air, and this condition is maintained for 30 minutes or more. , lasting up to 2 hours. At this time, since the tatami support frame 10 supports the tatami mats 20 without contacting each other and while forming a space between the tatami mats 20 for hot air to enter, the heat of the hot air is uniformly applied to each tatami mat 20. pervasive.
Therefore, most of the 20 tatami mats inside the drying room 3
Uniform drying and heating are possible.
The hot air after heating is discharged from the hot air suction duct 8 to the outside via the exhaust duct 9. Note that the heat generation temperature of this hot air generator 7 is automatically adjusted by an automatic temperature controller. During this drying process, the central portion of each tatami mat 20 is heated to a temperature of 60° C. or higher. During this heating, pests, especially mites, inside the tatami are completely killed by the heat.

Note that if the tatami mat 20 to be heated is made of a synthetic resin material, the temperature inside the drying chamber 3 is set to a temperature lower than that of a normal tatami mat, depending on the thermal characteristics of the material. .

Modified example of the invention In the above embodiment, the wheel 14 is attached to one side of the leg frame 11, and the attachment plate 15 is provided on the other side, but the tatami support frame 10 is not provided with the attachment plate 15 or the wheel 14 at the front and rear. Therefore, it is not limited to the structure as in the embodiment.

Effects of the invention In this invention, since the drying chamber for drying tatami mats is attached to the vehicle, the tatami mats can be dried in a position close to the tatami mats to be dried. Since the tatami mats are supported while forming a hot air circulation space between them, the drying efficiency of the tatami mats (heating efficiency of the tatami mats) is good, and it becomes possible to exterminate parasitic pests on the tatami mats in a short time.

In particular, the present invention has the following unique effects. The tatami mats inside the drying room are supported by the tatami support frame while creating a hot air circulation space between the tatami mats.
The drying efficiency of tatami mats (heating efficiency of tatami mats) is good, and it is possible to exterminate parasitic pests, especially mites, from tatami mats in a short time. In addition, the rotation of the rollers allows the tatami mats to be put in and taken out with light force while being supported by the frame so that they do not fall over, making it easy to put in and take out the tatami mats, and the tatami mats can be stored neatly in the drying room. .
