Abstract

PURPOSE:To effectively operate the extermination of ticks, especially, epidermic ticks, which inhabit especially in bedding clothes such as bedding, cushion and blanket by providing a rolling limit setting mechanism to freely set the width position of compressed rolling motion and a hot air circulating mechanism to send and circulate hot air at 50-90 deg.C to a non-permeable bag body which is covered by these mechanisms. CONSTITUTION:The hot air at 50-90 deg.C is sent and circulated from the hot air circulating mechanism into the non-permeable bag body and to the bedding, cushion and blanket, etc., which are objects to be dried, the compressed rolling motion is executed with a compressive roller and slave roller in a compressing mechanism. In such a case, when the above mentioned objects to be dried are compressed, the air of high humidity included in bedding cotton in an internal part is turned out. When the compression is removed and the bedding is restored to original thickness, since the hot air supplied from the hot air circulating mechanism is sucked in, the temperature of the internal part is immediately raised for an object to be dried and the objects can be dried in a state >=50 deg.C. Accordingly, the ticks living in the object are exterminated without any escape.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to futons, cushions, blankets, etc., especially in bedding.
The present invention relates to a method and a device for exterminating mites such as Dermatophagoides mites, which breed and cause various harms to the human body.

[Conventional technology] In recent years, as research on allergic asthma has progressed, it has been discovered that the causes of allergic asthma differ from person to person, such as mold and pollen, but the majority of causes are found in indoor dust. It became known as a tick. By the way, the above-mentioned mites are thought to be Dermatophagoides nigricans, etc., and they also eat the food spilled on the tatami mats, but their favorite food is human dander, and they become more active in hot and humid environments. The place to satisfy is the futon.

It is said to be found especially in bedding, such as cushions and blankets.

On the other hand, according to the recent housing situation, with the increasing number of buildings made of reinforced concrete, especially in housing complexes, the indoor airtightness tends to become highly humid, making it suitable for the above-mentioned Dermatophagoides mites. It tends to be a habitat.

Therefore, from the viewpoint of environmental hygiene as well as the above-mentioned circumstances,
In particular, there is a demand for extermination of the above-mentioned Dermatophagoides mites, etc., which infest futons, and five various proposals have been made.

First, when removing mites from futons, etc., it was done by thoroughly drying the futons. In this sense, futons have traditionally been handled by drying them by drying them with insects, but this method was primitive and dependent on the weather, and also took a long time. Therefore, in recent years, for various reasons, as a means of drying futons, etc., a means of drying futons etc. by blowing @ air onto the futons etc. using a hot air blower device called a so-called futon dryer etc. is often used. It looks like this.

On the other hand, in addition to drying futons and the like, there is also a method of directly exterminating dust mites by vacuuming them using an fa vacuum cleaner.

rProblems to be Solved by the Invention] As described in the prior art, methods for removing mites from futons and the like include drying them with warm air using a so-called futon dryer, and directly suctioning mites with a vacuum cleaner. There was a way to get rid of it. Furthermore, in addition to the one or more extermination methods, there is also a method of extermination using insecticides, etc., but with this method, the insecticide remains inside the futon cotton and the odor remains, and it is more or less harmful to the human body. Harmful, especially for people with allergic asthma.

If the trachea becomes sensitive, it can even cause seizures and have an adverse effect.

Currently, it is not possible to make real eyebrows, and the same is true for other methods.

First of all, the method using a vacuum cleaner can suck and exterminate the dust mites on the surface of the futon, but it has the disadvantage that it is completely ineffective against the dust mites that live inside the hot and humid cotton of the futon. there were. However, fl
! There have been reports that frequent suction cleaning with a scavenger suppresses the proliferation of mites and alleviates allergic asthma attacks, but this cannot be said to be a fundamental extermination of mites.

Next, there is the case where hot air drying is performed using a conventional futon dryer, but here the main purpose is to dry the futon with warm air, and there is a possibility that the direct purpose is not to exterminate dust mites. Ta. That is, many conventional futon dryers are of the portaple type, and the configuration is that indoor air is sucked into the futon dryer, and the air is warmed by a hot air blower consisting of an air blower and a heater installed inside the futon dryer. J
A warm air blowing mat is sandwiched between the futon spread on the bed and another futon, and the futon is dried while applying heat, by drying the futon as described above.

The humidity inside the futon decreases, making it difficult for dust mites to grow. Furthermore, it is said that the Dermatophagoides mites will die if heated at a temperature of 50° C. or higher for several minutes.

However, when drying using the futon dryer, only the surface of the futon is dried, and since the futon cotton inside is entangled with loose fibers, it has extremely high heat retention properties, and the futon dryer does not dry the futon. - It was difficult for the increase in surface temperature due to drying to be transmitted to the inner cotton of the futon.

Therefore, from the point of view of mite extermination, the mites that were present near the surface of the futon in contact with the warm air blowing mat at the beginning of drying will move into the relatively low-temperature cotton of the futon as the heating and drying progresses. When the futon drying is finished and the temperature drops, the habitat range returns to its original size, so some conventional futon dryers have the disadvantage that they are not effective in exterminating mites.

Therefore, the present invention has been made in view of the above drawbacks,
Dust mites that live in bedding, especially futons, cushions, blankets, etc.
The object of the present invention is to provide a method for exterminating bedding, etc., and a device therefor, which is particularly effective in exterminating Dermatophagoides mites.

[Means for Solving the Problems] Therefore, the present inventor attempted to achieve the above object by based on the following viewpoints.

In other words, it lives in bedding, such as futons, cushions, and blankets.
Mites cause various harms to the human body.

In particular, studies on the ecology of the Dermatophagoides mites have revealed that heating them at temperatures of 50°C or higher for several minutes will kill them.

Therefore, in order to exterminate the above-mentioned Dermatophagoides mites, it is sufficient to heat and dry the bedding, etc. where they live. conduction is extremely poor, and even though the surface temperature rises considerably due to heating and drying, the temperature inside the futon cotton does not rise that much and a high humidity state is maintained. In addition, mites, which are arthropods, are small, with a body length of about 0.1 to 0.5 mm, but they move freely inside the futon cotton, so to exterminate the mites, it is necessary to
It is necessary to uniformly heat and dry the interior of the bedding, etc. mentioned above.

As a result of various experiments, the inventor of the present invention applied external pressure to the bedding to expel the high-temperature air contained inside it, and then after removing the pressure, When the fibers such as futon cotton inside the bedding are restored.

If you supply hot air with high temperature and low humidity to the outside.

It was discovered that the above-mentioned bedding could be uniformly heated and dried in a short period of time by sucking this, and this led to the completion of the present invention.

In light of the above, the gist of the present invention is to have the following configuration.

That is, two guide rails are arranged parallel to each other in the longitudinal direction of the base frame, and a compression roller is attached to the guide rail in a horizontal direction and performs a rolling motion, and a Between the driven rollers,
A compression mechanism in which a compressing rolling motion is performed by the compression roller and a driven roller when a futon, cushion, blanket, etc. to be dried is sandwiched, and a width position of the compression rolling motion can be freely set. The gist of the present invention is to consist of a rolling limit setting mechanism, and a hot air circulation mechanism that blows and circulates hot air at 50 to 90 degrees Celsius through an air-impermeable bag covered with these mechanisms.

This is a mite extermination device for bedding, etc., and a mite extermination method such as 9-m, in which the mite extermination device exterminates mites.

[Function] Next, the function of the present invention will be explained. 1. By operating the tick extermination device according to the present invention, hot air of 50 to 90 °C is blown and circulated from the hot air circulation mechanism into the non-breathable bag body. When you get to know each other, there is mutual pressure! By means of the first mechanism, the objects to be dried, such as futons, cushions, and blankets, are subjected to compression rolling motion by the compression roller and the driven roller, and at this time, the objects to be dried are compressed.

The high humidity air contained in the futon cotton inside is expelled, and when the compression is removed and the original thickness is restored, the hot air supplied from the hot air circulation mechanism as described above is sucked in. As a result, the internal temperature of the material to be dried increases rapidly, and the material to be dried can be dried at a temperature of 50° C. or higher.

Therefore, the mites living in the material to be dried have no place to escape and die.Furthermore, the dryer is able to dry the material in a shorter time than conventional dryers of this type. It is.

[Example] The present invention will be explained in detail below based on the example shown in the drawings.

First, FIG. 1 is a partially cross-sectional side view for explaining the outline of the tick extermination device according to the present invention.
The figure is a plan view showing the same ←1 cross section. In this embodiment, the material to be dried was a futon, but as will be described later, there is no problem in using a cushion other than a futon, such as a blanket.

First, as shown in the figure, a futon 15, which is an object to be dried, is placed inside a guide rail 2 arranged parallel to the longitudinal direction on a base frame l.

Furthermore, one edge portion in the longitudinal direction of the futon 15.

It is sandwiched between the compression roller 3 and the driven roller 4, and! It is held by a holding tool 5 provided at the longitudinal end of the base frame l.

Further, the other edge portion is similarly held by the holding tool 5'. Here, the clamping tool 5.5'
Because a part of it is made of strong rubber or elastic materials such as springs, it can be dried even if the length of the material to be dried changes in the longitudinal direction.

The material to be dried is placed on the base frame 1.

Reference numerals 7 and 8 in Fig. 1 are a right-hand limit switch 7 and a left-hand limit switch 8, respectively, which indicate the rolling range of the compression roller 3 that rolls along the guide rail 2. The right limit switch 7 and the left limit switch 8 are connected to a motor 9, and either end of the bracket 16 in the longitudinal direction that rolls together with the compression roller 3 is connected to the right limit switch 7 and the left limit switch 8. When it comes into contact with either the left limit switch 7 or the left limit limit switch 8, the rotation of the motor 9 is reversed, and the bracket 16 and the compression roller 3 roll. It is assumed that the setting position of the switch 8 is freely adjustable in the longitudinal direction. Therefore, even when drying a cushion smaller than the futon 15, the right-end limit switch 7 and the left-end limit switch 8 are set to a rolling range suitable for the length of the cushion.

Next, within the base frame 1, a motor 9 and a screw shaft 11 are arranged so as to transmit the rotation of the motor 9 via a belt 1O.
As shown in the figure, a circulation dryer 12 is provided, and this circulation dryer 12 blows dry hot air from a blower duct 13, sucks in humid air from a suction duct 14, dehumidifies and heats the air, and blows the air again. The structure is such that air is blown from the duct 13. Furthermore, if the intake air temperature reaches the upper limit setting temperature (90° C.) or higher, the heater of the circulating dryer 12 shall be stopped, and the upper limit setting i8! If the temperature drops by 5°C or more from 90°C.

The heater is energized again. Further, the air blowing duct 13 and the air suction duct 14 are provided so as to open at the ends of the base frame 1 in the longitudinal direction, respectively.

Next, FIG. 3 is an enlarged view of the main part of FIG. 1, and FIG. 4 is a side view showing a partial cross section of FIG. 3. As shown in FIG. 1, the screw shaft 11 has a movable screw A bracket 16 with a hole is screwed together, and a compression roller 3 is attached to the bracket 16, and connecting rods 17 are fixed and erected at both ends of the compression roller 3, and are driven by the connecting rods 17. A roller 4 is pivoted. Here, in order to be able to change the distance between the compression roller 3 and the driven roller 4, that is, the pivoting position of the driven roller 4,
The connecting rod 17 can be changed depending on the thickness of the object to be dried.
As shown in the figure, a bearing groove 18 is provided on the third floor.

In addition, in FIGS. 1 and 2, the reference numeral 19 indicates the support rod 19.
The supporting rods 19 are inserted into the holes provided at the four corners of the upper surface of the base frame 1 to form a framework, and the non-breathable bag body 6 is stretched. Further, although not shown, the non-breathable bag 6 is provided with an entrance that can be easily opened and closed with a zipper so as not to interfere with taking in and taking out the items to be dried.

On the other hand, to briefly explain its operation with the above configuration,
The futon 15 has already been placed on the base frame 1, and one of the four longitudinal parts of the futon 15 is sandwiched between the compression roller 3 and the driven roller 4, and is also pinched by the clamping tool 5. The other end of 15 is held by the holding tool 5 and stretched on the base frame 1. When the mite extermination device according to the present invention is activated, the circulation dryer 12 and the motor 9 are activated, and the circulation dryer 12 blows dry hot air from the air duct 13 into the non-breathable bag body 6. Air is blown, while air suction duct 1
Highly humid air is sucked in from 4. The rotational force of the motor 9 is transmitted to the screw shaft 11 by the V-belt 10, thereby causing the bracket I6 and the compression roller 3. The driven roller 4 moves while compressing the futon 15, and the bracket 16
Mituto switch 7 as long as either end of the longitudinal direction is on the right side.
Alternatively, when the left limit switch 8 is contacted, the direction of rotation of the motor 9 is reversed due to the connection with the motor 9, thereby causing the bracket 16, the compression roller 3 and the driven roller 4 that are pivoted thereon to rotate in the opposite direction. It is something that allows you to move to.

[Effects of the Invention] Since the eleventh invention is configured as described above, it produces the effects described below.
