Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for controlling mites living on futons and the like used in homes, inns, and the like.

BACKGROUND OF THE INVENTION In recent years, as houses have become more airtight, indoor temperatures and humidity have become higher. As a result, dust mites are increasingly found indoors. It is said that 90% of childhood illnesses are caused by dust mites, and the majority are caused by dust mites attached to bedding. Therefore, by controlling the mites that attach to bedding, most cases of childhood mites can be prevented. Washing the futon is a method for controlling dust mites attached to the futon, but washing and drying a large futon requires a lot of effort and is troublesome. In addition, dust mites are sensitive to heat, so in business, a large simple dryer is used to heat the futon, but futons are a type of insulator, and while mites on the outer skin can be easily removed, dust mites inside the futon can be removed. This requires heating for a long time, which increases costs. However, it is not practical to install it at home. Therefore, the most commonly used method at home is to use a vacuum cleaner to suck it up. However, it takes a considerable amount of time to control mites from one futon, and even if it takes a long time, it is not possible to completely control mites. Therefore, it is necessary to vacuum for a long time every day, which requires a lot of effort.

Furthermore, since the vacuum cleaner was applied strongly from above the futon, the fabric of the futon was damaged.

Problems to be Solved by the Invention As mentioned above, there is currently no suitable means for controlling mites living on futons.

The present invention aims to provide a device for easily and reliably controlling mites living on futons.

Means for Solving the Problems In order to solve the above problems, the present invention attempts to control dust mites by pressurizing a futon and heating it in this state.

Function: In the present invention, mites can be easily removed using the following device. In other words, mites are generally sensitive to heat. Although it varies slightly depending on the type of mite, for example, heating it to 50°C can kill it in a few minutes. However, since a futon is an insulating material with a built-in air layer, heating only raises the temperature on the surface. Therefore, in order to heat the inside to the specified temperature, you must heat it for a long time or set the heating device to a high temperature. I needed to. However, in the present invention, the futon is easily stored and the futon is pressurized, so the amount of air contained within the futon is reduced and its thickness is reduced. When heated in this state, heat is easily transferred to the entire futon by conduction, and the temperature can be reached to kill the mites on the entire futon.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a mite control device according to an embodiment of the present invention. In this embodiment, the pressurizing device 1 includes a device 3 for tightening the plate-shaped body 2.

Furthermore, in this embodiment, a heating device 4 is provided inside the plate-shaped body 2 and is integrated therewith. In FIG. 1, a futon 5 is folded in two and placed between the plate-like bodies 2. Thereafter, the futon 5 is pressurized by the pressurizing device 1, and air is removed from the futon 5, reducing its thickness. The plate-like body 2 is preferably made of a heat-resistant material and is less likely to deform due to temperature rise. For tightening, device 3 is the first
In the figure, the futon 5 can be easily pressurized by tightening the upper plate-like body with bolts.

Since the purpose of the tightening device 3 is to pressurize the futon 5, any tightening device other than the combination of bolts and nuts as in this embodiment may be used as long as it serves this purpose. The heating device 4 is a surface heater provided inside the plate-shaped body 2 (on the side where the futon 5 is located), and is equipped with a safety device and a temperature control device, but these are not shown in the figure because they are not the main factors of the present invention. It is omitted. In this embodiment, since no heat insulating material is provided on the sides of the futon 5, the side surfaces of the futon 5 will be difficult to heat unless the heater extends to the outside of the futon 5.
Dust mites gather in this area, making it difficult to kill them. Further, if a heat insulating layer is provided on the plate-like body 2 to prevent the heat of the heater from escaping to the outside of the plate-like body 2, the thermal efficiency will be improved.

Examples of heating will be described below.

Fold the futon 5 in half (approximately 1rd) and place it between the L plate-like bodies 2, pressurize the futon with a tool, and reduce the thickness to 1 of the initial thickness.
The pressure was increased to /3. In this state, when the heater is heated (350W for the lower plate, 400W for the upper plate), the entire futon 5 can be easily heated by conduction because the futon 5 contains almost no air layer. The temperature in the center of the futon reached 60℃ in minutes. This state is about 1
It was held for 5 minutes to kill the mites. That is, the number of mites that were approximately 20,000 before heating decreased to less than 100 after heating. Furthermore, when the same procedure was carried out without applying pressure, the temperature at the center of the futon 5 did not reach 60° C. even after about one hour. Furthermore, the side temperature of the futon 5 was 35°C. In this case, the number of mites was 20,000 before heating, but it was confirmed that about 5,000 mites were still alive after heating.

As described above, according to the device of the present invention, mites can be easily killed. However, since the dead bodies of mites cannot be disposed of, it is even more effective to suck up the dead bodies with a vacuum cleaner. Further, according to the method of the present invention, the futon is kept in a good dry state. In other words, after the heat treatment of the present invention, dust mites are less likely to grow.Therefore, as mentioned above, there is no need to collect dust mites with a vacuum cleaner even if the futon is heated every day. However, once every 10 days or twice a month is sufficient.

Example 2 In Example 1, the temperature rise on the sides of the futon 5 is delayed.

In this embodiment, as shown in FIG.
is arranged. This heat insulating material 6 is preferably made of flexible urethane foam.

The heat insulating material 6 may be inserted after the futon 5 is pressurized, or the futon 5 and the heat insulating material 6 may be placed in advance and then both may be pressurized at the same time. In this embodiment, since heat dissipation is reduced, the area of the heater may be reduced. When heat treatment was performed under the same conditions as the heat treatment in Example 1,
Almost the same results as in Example 1 were obtained.

Embodiment 3 In this embodiment, as shown in FIG. 3, the pressurizing device 1 and the heating device 4 are separate. The heating device 4 is a flexible aluminum laminate film to which a heater wire is attached. Example 1 A futon 5 is wrapped around this heating device 4.
Heated under the same conditions. As a result, it was possible to control mites in almost the same manner as in the example. Also, the temperature rise is futon 5
Because of the good adhesion between the heating device 4 and the heating device 4, it was possible to substantially shorten the time by about 10%. Further, in this embodiment, a passage is required for moisture evaporated by heating to escape to the outside.

Example 4 As shown in FIG. 4, the futon 5 is placed in a container 7.

A plate-shaped body 2° constituting the heating device 1 is placed on the futon 5 and pressure is applied to this plate-shaped body 2''.When a predetermined pressure is applied, it is fixed with a fixing bar 3°.In this embodiment, the container The plate-like body 2'' is fixed by inserting the fixing bar 3' into a hole provided at an appropriate position in the container 7 and the plate-like body 2''.The heating device 4 is integrated into the container 7 and the plate-like body 2''. Although the heater used in the heating device 4 is not particularly limited, it is preferable to use a self-control heating element (PTC heater) because the temperature distribution becomes constant. Moreover, there is no problem in providing the heater on the side surface of the container 7, and in this case, the heating time can be shortened. Furthermore, by providing the container 7 with a heat insulating layer, it is possible to prevent heat from being released.

When the heat treatment was carried out under the conditions shown in Example 1 using the apparatus shown in FIG. 4, the mites could be killed in the same manner as in Example 1. Further, in this example, since there is little heat dissipation, the heating time can be substantially reduced by 20 to 30%.

In the above explanation, we have shown how to easily store futons and prevent dust mites on futons, but as you can see from the above explanation, it is also possible to prevent dust mites in bedclothes other than futons such as blankets, sheets, pillows, cushions, etc. is also valid.

Effect of the invention As described above, according to the present invention, the following effects can be obtained.

That is, in the present invention, since the futon is pressurized and the air in the futon is expelled before heating, the entire futon can be easily brought to a predetermined temperature in a short time. Therefore, mites hiding in the futon can be reliably controlled. Also,
By heating, the moisture contained in the futon can be easily removed and the futon can be brought into a good dry state.

As described above, by using the apparatus of the present invention, a comfortable and clean futon can be obtained.
