Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower bed which cools a bed environment by blowing air.

2. Description of the Related Art A conventional blower bedding of this type includes an air supply device 14 including an air supply pipe 13 having a plurality of air discharge pores 12 as shown in FIGS. 3A and 3B, and the air supply device. An air compressor 15 for sending air to the core 14 and a core material 17 having a plurality of small projections 16 on the surface thereof.
The air compressed by is blown out from the air discharge hole 12 to blow air to the human body.
(For example, Japanese Laid-Open Patent Publication No. 58-121917) Problems to be Solved by the Invention However, in the above-mentioned configuration, since the pipe is used for the ventilation path, it is difficult to fold and the storability when not in use However, since the pipes are connected in series, the amount of air blown out will differ between the position near the air compressor and the position far from it, and the compressor must be used to ensure a sufficient amount of air because the air flow path cannot be made large. In addition, there is a problem that noise and vibration during driving are large, which becomes a factor that disturbs sleep.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a comfortable sleeping environment by using bedding that is lightweight and has a good storability.

Means for Solving the Problems In order to solve the above problems, the blown bed of the present invention has a first mat layer having an end portion and a plurality of groove portions penetrating the end portion on the back surface, and the first mat layer. A first cloth that is in close contact with the entire surface of the mat layer and has a size larger than that of the first mat layer, and a second mat that is in close contact with the surface of the first cloth layer and has the same size as that of the first mat layer. A layer and a second fabric that is in close contact with the surface of the second matte layer and that is about the same size as the first fabric.
From the second fabric to the second matte layer and the first
A plurality of blow-out holes penetrating through the fabric to the position of the groove of the first mat layer, and the first and second fabrics provided at the lower side of the second mat layer 3 cloth, an air passage formed by the first cloth and the third cloth, an opening provided in a part of the air passage, an air blowing unit, the opening and the air blowing unit. It is composed of a duct for communication.

Operation According to the present invention, the air blown by the blower means is filled in the ventilation passage through the duct to form a kind of chamber, and is sent to the groove portion on the back surface of the mat from the blowout holes of each part of the mat. Air can be blown out evenly. Moreover, since it is lightweight, it can be easily moved, stored, and installed.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 and FIG. 2, 1 is a blower, 2 is a first mat layer using hard cotton of a chemical fiber, and the surface of the first mat layer 2 is a non-breathable first cloth. 3, the second mat layer 4 using hard cotton having a good hygroscopic property, and the second fabric layer 5 having a good hygroscopic property are sequentially laminated and integrated by ultrasonic processing from the end to the end of the first mat layer 2. Is provided with a plurality of groove portions 6, and at the position of the groove portions 6, a plurality of blowout holes penetrating from the first mat layer 2 to the second fabric 5 are provided.
The first cloth 3 and the second cloth 5 have a larger area than the first mat layer 2 and the second mat layer 4, and the first cloth 3 and the second cloth 5 are surrounded by a non-woven fabric. The first cloth 3 and the third cloth 8 form a ventilation passage 9 by being brought into close contact with the breathable third cloth 8. Further, a circular opening 10 is provided in a part of the ventilation passage 9 and is composed of a flexible duct 11 connecting the opening 10 and the blower 1.

In the above structure, since the mat portion is made of a flexible material, it is easy to store and has good hygroscopicity due to the use of hard cotton, which causes discomfort even when the user sweats. Never.

In addition, when the groove is formed on the back side of the first mat layer by ultrasonic processing, the groove is formed on the front side of the second mat layer, and the front side has unevenness, so that the user and the bedding surface are in close contact. Since it does not have any airflow, it is comfortable to use even in summer.

In addition, here, hard cotton of scientific fiber was used for the mat layer,
It may be molded with resin such as urethane foam.

Further, it is clear that depending on the processing method, the effect of blowing air can be sufficiently obtained even if the surface of the second mat layer has no unevenness or another uneven shape.

Next, another embodiment of the present invention will be described. The difference from the above-mentioned example is that the second mat layer is subjected to antibacterial / deodorant processing and uses a fiber having a good hygroscopic property. Since the generation of unpleasant odor and the generation of unpleasant odor are prevented, even a bedridden person can comfortably use it.

EFFECTS OF THE INVENTION As described above, according to the blown bed of the present invention, the following effects can be obtained.

(1) Since the groove portion is provided on the back surface of the mat, the groove portion can have a sufficient size as a ventilation path.
An air blower with low air resistance in the ventilation path and a low noise blower can blow air enough to make the human body feel cool.

(2) The air blown by the blower means fills the ventilation passage through the duct to form a kind of chamber, and is blown from the groove to the groove on the back of the mat from here, so that it is evenly blown to each part of the mat. The airflow is evenly distributed to each part, which has the effect of giving a cool feeling to the whole body.
