Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for exterminating Dermatophagoides mites, etc., which occur and breed in futons, cushions, blankets, etc., and especially in bedding, and which cause various harm to the human body. It is related to the device.

[Prior Art] In recent years, as research on allergic asthma has progressed, it has become clear that the causes of allergic asthma differ from person to person, and can be caused by mold or pollen, for example, but the majority of the causes are found in indoor dust. It has become known that these mites are By the way, the above-mentioned mites are thought to be Dermatophagoides mites, etc., and they also eat food spills and hair on tatami mats, but their favorite food is human dander.
Activity increases in hot and humid environments, and places that meet these conditions include futons, cushions, blankets, etc.
It is said to be especially found in bedding.

On the other hand, according to the recent housing situation, especially with the increasing number of buildings made of reinforced concrete such as housing complexes, indoor environments tend to be highly airtight and hot and humid. It tends to be a habitat.

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

First, when removing mites from futons, etc., it was done by thoroughly drying the futons.
In this sense, when handling futons, people had traditionally dried them by drying them with insects, but this method was primitive and depended on the weather, and it took a long time. . Therefore, in recent years, for various reasons, a method of drying futons, etc. by blowing warm air onto them using a warm air blower called a futon dryer has become increasingly popular. It is becoming more and more common.

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

[Problems to be Solved by the Invention] As described in the prior art, there are two methods of removing mites from futons, etc.: drying them with hot air using a so-called futon dryer, and directly suctioning mites with a vacuum cleaner. I found a way to get rid of it. Furthermore, in addition to the above methods of extermination, methods of extermination using insecticides, etc., can be considered, but with this method, the insecticide remains inside the futon cotton, leaving an odor and causing more or less human body damage. It is also harmful to patients, especially those with sensitive tracheas, such as those with allergic asthma, and can even cause attacks and have an adverse effect, so it has not been put to practical use at present. The same applies to other methods.

First of all, the method using a vacuum cleaner has the disadvantage that, although it is able to suction and exterminate dust mites on the surface of the futon, it is completely ineffective against dust mites that live inside the hot and humid cotton of the futon. It was hot. However, although there are reports that frequent suction cleaning with a vacuum cleaner suppresses the proliferation of mites and alleviates allergic asthma attacks, it is difficult to say that it completely eliminates mites. be.

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 the direct purpose is not to exterminate dust mites. It was hot. That is, many conventional futon dryers are portable, and their configuration is to suck indoor air into the futon dryer, warm the air with a warm air blower consisting of an air blower and a heater installed in the futon dryer, A mat that blows hot air is inserted between a futon spread on a folded mattress and another futon, and the futon is dried while applying heat. The humidity inside the futon decreases, making it difficult for dust mites to live there. Furthermore, it is said that the Dermatophagoides mites will die if heated for several minutes at a temperature of 50°C or higher.

However, when drying with the above-mentioned futon dryer, only the surface of the futon is dried, and since the futon cotton inside is in a state where fine fibers are intertwined, it has extremely good heat retention, 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 inside of the futon cotton.

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 pine at the beginning of drying, move into the relatively low-temperature cotton of the futon as the heating and drying progresses. When the futon drying process is finished and the temperature drops,
Since the habitat range of the mites will be restored to its original range, conventional futon dryers have the drawback of not being effective in exterminating mites.

Therefore, the present invention was made in view of the above-mentioned drawbacks, and provides a method for exterminating mites from bedding, etc., which is effective in exterminating mites, especially Dermatophagoides mites, living in bedding such as futons, cushions, and blankets. The purpose is to provide such equipment.

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

In other words, in order to exterminate mites, especially Dermatophagoides mites, which inhabit bedding such as futons, cushions, and blankets and cause various harm to the human body, research on their ecology has shown that heating at a temperature of 50 degrees Celsius or higher for a few minutes can It is known that he will die.

Therefore, in order to exterminate the above-mentioned Dermatophagoides mites, it is sufficient to heat and dry the bedding, etc. in which they live, but it is not necessary to heat and dry the bedding etc. in which they live. Bedding and the like have extremely poor conduction of heat, 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, although mites, which are arthropods, are small with a body length of about 0.1 to 0.5 mm, they move freely inside the bedding, so exterminating the mites includes the inside of the bedding mentioned above. It is necessary to heat and dry evenly.

As a result of various experiments, the inventor of the present invention applied external pressure to the bedding to expel the high humidity air contained inside it, and then removed the pressure. Later, when the fibers such as futon cotton inside the bedding are restored, by supplying high-temperature, low-humidity hot air to the outside, this can be sucked in and the bedding can be uniformly heated and dried in a short time. This discovery 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.

In other words, there are 2 parallel lines in the longitudinal direction of the base frame.
A book guide rail is arranged, and the material to be dried is placed between a compression roller that is engaged in a direction that horizontally extends the guide rail and performs rolling motion, and a driven roller that follows the movement of the compression roller. A compression mechanism that performs compression rolling motion by the compression roller and a driven roller when a futon, cushion, blanket, etc. is sandwiched therein; and a rolling limit setting mechanism that allows the width position of the compression rolling motion to be freely set. and a hot air circulation mechanism that blows and circulates hot air at a temperature of 50 to 90 degrees Celsius through a non-breathable bag covered with these mechanisms. This is a mite extermination method for bedding, etc., in which mites are exterminated using the mite extermination device.

[Function] Next, to explain the function of the present invention, by operating the tick extermination device according to the present invention,
From the hot air circulation mechanism, air is heated from 50℃ to 90℃ inside the non-breathable bag.
℃ hot air is now blown and circulated, and the compressing mechanism applies compression rolling motion to the items to be dried, such as futons, cushions, blankets, etc., by the compression roller and driven roller. At this time, when the material to be dried is compressed, the high humidity air contained in the futon cotton inside is expelled, and when the compression is removed and the material is restored to its original thickness,
As the hot air supplied from the hot air circulation mechanism is sucked in as described above, the internal temperature of the material to be dried rapidly rises, raising the temperature to 50°C.
Drying can now be done in the above conditions.

Therefore, the mites living in the material to be dried have no place to escape and die.Furthermore, this type of dryer is designed to be 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 exterminating device according to the present invention, and then FIG. 2 is a partially cross-sectional plan view. Here, in this embodiment, the material to be dried is a futon, but as will be described later, there is no particular problem if it is a cushion, a blanket, etc. other than a futon.

First, as shown in the figure, a futon 15 which is an object to be dried
is placed on the inside of a guide rail 2 arranged parallel to the longitudinal direction on the base frame 1, and furthermore, one longitudinal edge of the futon 15 is placed between the compression roller 3 and the driven roller 4. It is sandwiched and held by a holding tool 5 provided at the longitudinal end of the base frame 1 . Further, the other edge portion is similarly held by the holding tool 5'. Here, since a part of the clamping tools 5, 5' is made of strong rubber or an elastic material such as a spring, even if the longitudinal length of the object to be dried changes, Objects are stretched onto the base frame 1.

Reference numerals 7 and 8 in the figure are a right limit switch 7 and a left limit switch 8, respectively, which set 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 the longitudinal end of the bracket 16 that rolls together with the compression roller 3 is connected to the right limit switch 7 or the left limit switch. 8
When the motor 9 comes into contact with either of them, the rotation of the motor 9 is reversed, and the bracket 16 and the compression roller 3 are made to roll, and the setting positions of the right limit switch 7 and the limit switch 8 are freely adjustable in the longitudinal direction. Suppose there is. Therefore, futon 1
Even when drying a cushion smaller than 5, the right limit switch 7 and the left limit switch 8 are set to a rolling range suitable for the length of the cushion.

Subsequently, a motor 9 and a screw shaft 11 are mounted on a V-belt 10 in the base frame 1.
It is arranged to transmit the rotation of the motor 9 via the motor 9, and a circulating dryer 12 is provided as shown. This circulation dryer 12 has a structure in which dry hot air is sent through a blower duct 13, moist air is sucked in through a suction duct 14, the air is dehumidified and heated, and the air is sent again through the blower duct 13. Furthermore, if the intake air temperature reaches the upper limit set temperature (90°C) or higher, the heater of the circulation dryer 12 shall be stopped, and if the temperature drops by 5°C or more from the upper limit set temperature (90°C) Then, 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.
FIG. 4 is a side view showing a partial sectional view of FIG. 3. As shown in the figure, a bracket 16 with a movable screw hole is screwed into the screw shaft 11, and a compression roller 3 is pivotally attached to the bracket 16, and connecting rods 1 are attached to both ends of the compression roller 3.
7 is fixed and erected, and the connecting rod 1
A driven roller 4 is pivotally attached to 7. Here, in order to be able to change the distance between the compression roller 3 and the driven roller 4, that is, to change the pivoting position of the driven roller 4 depending on the thickness of the material to be dried, the connecting rod 17 has a structure as shown in the figure. A bearing groove 18 is provided in the three-stage shaft.

In FIGS. 1 and 2, reference numeral 19 indicates support rods 19, and the support rods 19 are inserted into perforations provided at the four corners of the upper surface of the base frame 1 to stand up to form a framework. shall be upholstered. Further, although not shown, the non-breathable bag 6 is provided with an entrance that can be easily opened and closed with a fastener so as not to interfere with taking in and out the materials to be dried.

On the other hand, to briefly explain the operation of the above configuration, the futon 15 is already placed on the base frame 1, and one longitudinal end of the futon 15 is sandwiched between the compression roller 3 and the driven roller 4. The other end of the futon 15 is held by the clamping tools 5 and stretched over the base frame 1. Here, when the mite extermination device according to the present invention is operated, the circulation dryer 12 and the motor 9 are operated, and depending on the circulation dryer 12, the air duct 13
Drier hot air is blown into the non-breathable bag 6, while highly humid air is sucked in from the air suction duct 14. The rotational force of the motor 9 is transmitted to the screw shaft 11 by the V-belt 10, whereby the bracket 16, the compression roller 3, and the driven roller 4 move while compressing the futon 15. When either tip in the longitudinal direction contacts the right limit switch 7 or the left limit switch 8, the direction of rotation of the motor 9 is reversed due to the connection with the motor 9, thereby causing the bracket 16 and its shaft to The compression roller 3 and driven roller 4 that are attached to the roller 4 move in opposite directions.
