Abstract

PURPOSE:To promote the evaporation of water content for providing a comfortable sleep even without utilizing a fan and air conditioner by utilizing the gas permeability and ventilating property a mattress itself has. CONSTITUTION:A bed is provided with a gas permeable stand 1 supported spaced from a floor and a gas permeable mattress 4 placed on the stand 1. The stand 1 for supporting the mattress 4 thereon needs to have the gas permeability. A chair-like structure for example is used for the structure having the gas permeability. The stand 1 is supported spaced from a floor on which to bed is placed and needs to be spaced from the floor so that natural smooth convection is generated. For example, the chair-like stand 1 having meshes and gas permeability is held in a position about 40cm high from the floor by legs 2, 3. A lattice board having polyethylene resin cylinders arranged in the net-like form is laid on the stand 1 to provide a bed 4. The smooth progress of evaporation of water content in the lower side of the mattress 5 provides a comfortable sleep.

ある。Whether it is a futon or a Western-style bed, in the hot and humid summer of Japan, sleepiness is unavoidable, and it tends to rely on forced air blowing and cooling by a fan or an air conditioner. However, it is difficult to obtain comfortable sleep, and there is a drawback that it is easy to catch an air condition and a cold.

を完成した。[Means for Solving the Problem] The apparent moisture diffusion coefficient of the futon is 1/10 of the value in the air even if it is underestimated. Therefore, if this value can be utilized, it will evaporate even in an environment called tropical night in summer. The amount of latent heat radiated by is supposed to reach about 1/3 of the amount of sensible heat radiated. Therefore, it was thought that a comfortable bed can be obtained by promoting heat dissipation by latent heat under the futon, and as a result of research, the bed of the present invention was completed.

In the conventional mattress, the material is required to have a hygroscopic property, but in the case of the present invention, the moisture absorption is not so important because the moisture evaporates smoothly, and rather the air permeability is important. Of course, a mat made of various combinations of these materials may be used.

活かせる。[Function] When the heat is high, the water evaporating from the body moves through the mat to the room air under the bed without permeating the skin as sweat. Since the floor of the room and the bed of the bed are sufficiently open, moisture is easily diffused into free space by the naturally existing draft (convection) in the room air. Since the mat has good breathability, the effect of the draft extends partially into the interior of the mat. This effect is particularly great when the mat is made of a porous hollow elastic body or an open-cell porous elastic body. The smooth diffusion of water promotes heat transfer that dissipates the heat generated by the body as latent heat. Due to this effect, the rise in body temperature during hot weather and the wetting of the skin are suppressed, and comfort and hygiene can be maintained. Further, since it utilizes the natural draft and the promotion of water movement, it is effective even if the use of a cooling device or an air blowing device is eliminated. Further, since water evaporation is an innate function of the human body and is voluntarily performed according to the degree of necessity only when it is necessary to promote heat dissipation, the amount of evaporation is small when the need for heat dissipation is small. .. In the bed according to the present invention, since this function is utilized to the maximum, unlike the case of cooling or blowing air, it does not become too cold. As a result, it is a moderate bed for people who are not physically strong or who suffer from air conditioner disease, and healthy people can effectively utilize their physiological functions.

る。If an ordinary mattress is used as the mat, or if a mat made of a porous hollow elastic material or an open-celled porous elastic material is placed on the lower surface of the mat and an ordinary mattress is placed on the mat, the moisture can be absorbed. Due to the ease of use, the moisture that has conventionally stayed on the lower side of the comforter and was easily absorbed by the comforter cotton is dissipated, and the wetness of the comforter is suppressed. Since the moisture is smoothly dissipated, even if the material of the mattress, which has traditionally required hygroscopicity to have a low hygroscopicity, can be used practically, and then the futon contains a small amount of moisture and is easy to dry. Is. The maintenance work is reduced when used in a cold environment where condensation easily occurs, or when the product is used continuously for a long period of time.

を設けた。EXAMPLE As shown in FIG. 1, a breathable pedestal 1 having a grid-like mesh of 5 cm square was set up by legs 2 and 3 to be about a height from the floor.
On the bed held at a position of 40 cm, a mesh-shaped cylinder (diameter about 2 cm, length 90 cm) made of polyethylene resin called Air Cyclone (sold by Nishikawa Sangyo Co., Ltd.) was lined up and laid as a child's bed. I set it to 4. Kakemono 5 is a polyester cotton summer coat. It was carried out in a constant temperature and constant humidity room, but a windshield was provided so that the wind from the ceiling would not be directly applied to the subject 6.

In addition, the humidity of the skin (A), the temperature and humidity of the upper side of the rug (B), and the temperature and humidity of the lower side of the rug (C) were measured so that the transport phenomenon could be examined. Some also measured skin heat flux and room temperature and humidity.

First, a vinyl sheet was attached to the back surface of the base 1 to prevent evaporation, and then the vinyl sheet was peeled off after about 3 hours to allow evaporation.

と言う説があるから、この値は好ましい結果と言える。The change in humidity was found to be different between experiments. The temperature made a very simple and distinct universal change. Until the vinyl sheet was peeled off, the temperature gradually increased at all three points, and when the sheet was peeled off, the temperature at C dropped all at once, and at the other two points, the slight temperature difference gradually decreased. Figure 3 shows the changes in skin temperature before and after peeling the sheet. Inferring from the rate of temperature decrease seen in the figure, the final skin temperature decrease due to peeling the sheet is 2-3 ° C. The temperature in the bed when you are getting comfortable sleep is 33 ℃
Therefore, it can be said that this value is a desirable result.

You can get a good night's sleep.
