Description

[Detailed description of the invention] This invention relates to a sunroom for residential use.

Traditional sunrooms receive sunlight by
Since we only installed a window made of light-transmitting material such as glass on the south side, it is necessary to open and close the window to replenish oxygen, and it is not possible to keep the space inside the sunroom in an oxygen-enriched state at all times. Therefore, it could not be said that sufficient conditions were provided for people who needed a large supply of oxygen, such as the sick. This project aims to provide a sunroom that can solve these problems.

The proposed sunroom will be explained below with reference to FIGS. 1 and 2.

In Figure 1, 1 is a sunroom space created to receive a lot of sunlight, and a partition window 11 that partitions this space 1 from the outdoors is made of a light-transmitting material such as glass. . Reference numeral 12 denotes a partition wall such as aluminum sash that partitions the room 1 and the room 2 located inside the room 1.

As shown in FIGS. 1 and 2, the aluminum sash 12 has a drum 3 vertically installed therein, which constitutes an air passage extending in the vertical direction.
At the upper end of the side wall of this drum 3, a first opening 31 serving as one passage opening of the air passage is formed. Inside the drum 3, a circular oxygen selective permeable membrane 4 matching the inner diameter of the drum 3 is provided so as to close the air passage. Here, the oxygen selective permeable membrane is made of, for example, a polymer that has the property of selectively permeating oxygen from a side with a high oxygen partial pressure to a side with a low oxygen partial pressure. To describe this property in more detail, when air is forcibly supplied to one side of the oxygen selectively permeable membrane, oxygen in the air diffuses to the surface of the membrane, and as a result, the concentration of oxygen on one side of the membrane increases. The concentration of oxygen becomes higher than that on the surface side, forming a concentration gradient, and as a result, oxygen moves from the high concentration side to the low concentration side due to the diffusion effect.

Further, in this example, as shown in FIG. 2, in order to reinforce the oxygen selectively permeable membrane 4, a reinforcing membrane 41 through which air can freely permeate is provided on the underside of the oxygen selectively permeable membrane 4.

A second opening 32 is formed at the bottom of the drum 3 as the other air passage opening.
An air compressor 5 serving as an air supply means for supplying air to the oxygen selectively permeable membrane 4 is connected to this opening 32 via a supply pipe 51 .

Further, a suction pipe 52 is connected to the suction side of the air compressor 5, and the suction pipe 52 is disposed in the chamber 2, for example, and the suction port is located inside the aluminum sash 12.

For example, the air compressor 5 has a pressure of 3
It is possible to use one with a capacity of Kg/cm ² and a capacity of 50/mm. It is preferable to attach a filter 53 for removing dust to the suction pipe 52 as shown in FIG. 2, and this has the advantage that clogging of the oxygen selective permeation membrane 4 and the reinforcing membrane 41 can be suppressed. There is. Furthermore, an exhaust port 6 is formed at the bottom of the drum 3 for discharging air that does not pass through the oxygen selective permeation membrane 4 out of the air supplied into the drum 3 by the air compressor 5, This exhaust port 6 is connected to an exhaust pipe 61 whose outlet is located outdoors.

In an embodiment with such a configuration, by operating the air compressor 5, the air in the room 2 is sucked through the suction pipe 52 and guided into the drum 3, that is, into the air passage through the supply pipe 51. , is supplied to the oxygen selectively permeable membrane 4.

Therefore, as mentioned earlier, oxygen in the air is transferred to one surface of the oxygen selectively permeable membrane 4 (the surface opposite to the opening 31).
The oxygen concentration on one side becomes higher than the oxygen concentration on the other side, and as a result, oxygen selectively moves to the other side and permeates through this membrane 4.

And actually other components other than oxygen in the air,
For example, nitrogen, carbon dioxide, etc. also permeate through the oxygen selective permeation membrane 4, but due to the above-mentioned action, the permeation rate of oxygen is large, so the oxygen concentration of the air that permeates through this membrane is, for example, 25 to 30% by volume, which is normal. This value is considerably higher than the oxygen concentration of air (approximately 21% by volume).

As air with high oxygen concentration flows into the sunroom space 1 through the opening 31,
The oxygen concentration in the sunroom space 1 increases. On the other hand, among the air introduced into the drum 3, the air that has not passed through the oxygen selective permeable membrane 4 is removed from the exhaust port 6.
and is discharged to the outdoors via the exhaust pipe 61.

Since the proposed sunroom is like this, it has the effect of naturally increasing the amount of oxygen in the interior space 1 without opening or closing the window 11, and the oxygen-enriched air is supplied from above the drum 3. Room space 1
Since light oxygen is supplied to the oxygen selectively permeable membrane 4
Since the air rises from the air and is supplied into the sunroom space 1, the supply of oxygen is good and the oxygen-enriched air is supplied near the head of the human body.
There is an effect that this air can be suctioned well.
