Description

[Detailed Description of the Invention] <Industrial field of application> The present invention is a glass shelter provided in an opening or the like of a building filled with foamed resin particles to shield indoors and outdoors from heat, light, and line of sight. Moreover, the present invention relates to a solar heat utilization device that extracts the foamed resin particles and takes in sunlight into the room.

<Prior Art> As a conventional solar heat utilization device, there is a so-called passive system that directly takes in and uses sunlight incident from a window or the like.

That is, as a device for filling the foamed resin particles in the glass shelter, air pressure is applied to a storage tank that stores the foamed resin particles by a blower, and the air pressure causes the foamed resin particles to be pressure-fed from the feed pipe to the glass shelter, and inside the glass shelter. Fill by dropping. Then, the air in the storage tank is evacuated by the suction action of the blower, and the foamed resin particles in the glass shelter are extracted through the continuous return pipe below the glass shelter and returned to the storage tank.

<Problems to be solved by the invention> However, in the above device, when a plurality of independent glass shelters are provided, the glass shelters are sequentially filled and withdrawn from the glass shelter closer to the storage tank, and the foamed resin particles are distant from the glass shelter far away. May remain without being completely withdrawn. A similar problem also occurs due to the difference in the length of the return pipe connecting the storage tank and the glass shelter and the resistance inside the pipe.

For this reason, it is impossible to ensure the simultaneous filling and drawing with respect to a plurality of glass shelters, which also reduces the efficiency of solar heat utilization.

<Means for Solving Problems and Their Actions> Therefore, in the present invention, the drawing tube is provided with a sensor and a damper for opening and closing the tube by the sensor, and the sensor detects the flow state of the foamed resin particles in the drawing tube. As soon as there is no flow, the damper is closed and only the glass shelter is pulled out.

Therefore, since the air is not sucked from the glass shelter that has been completely drawn, the air suction force of the other glass shelters is not weakened, and the foamed resin particles can be completely drawn.

<Example> Hereinafter, the solar heat utilization apparatus of the building of this invention is demonstrated in detail based on drawing.

The figure is a schematic diagram showing the device of the present invention.

The main components of this apparatus are a storage tank 1 for storing expanded resin particles, a plurality of glass shelters 2a, 2b ... In which the expanded resin particles are filled, and further, for filling and extracting expanded resin particles. It is composed of a blower W and various pipes P1 to P5 for connecting the constituent members.

The storage tank 1 is a box having a sufficient volume to store the foamed resin particles. On the other hand, the glass shelters 2a and 2b
Is disposed in the south opening of the building and forms a predetermined space with a plurality of glass plates. Each of the glass shelters 2a, 2b ... Has a shape corresponding to the size of the room and the opening.

The upper portions 21 of the glass shelters 2a, 2b ... And the lower portion 11 of the storage tank are connected by a feed pipe P1. Further, the pull-out pipes P2a and P2b are attached to the lower portion 22 of each glass shelter 2a.
And the return pipe P2 connected to the drawing pipes P2a and P2b is connected to the upper part 12 of the storage tank.

The feed pipe P1 is provided with a switching damper A1 and the withdrawal pipe P1.
2a and P2b are provided with dampers B1 and B2, respectively, and sensors S1 and S2 are provided between the damper B1 and the glass shelter 2a and between the damper B2 and the glass shelter 2b in the extraction pipes P2a and P2b, respectively. The sensors S1 and S2 are optical sensors and the like, and detect the presence or absence of foamed resin particles flowing in the tube.

On the other hand, the blower W has its air intake port w1 connected to the storage tank upper portion 12 through a pipe P3. Further, the middle of the pipe P3 is opened to form an air supply port w2, the damper A2 is provided there, and the damper B3 is provided in the vicinity of the upper part 12 of the storage tank. Further, the air discharge port w3 of the blower W and the feed pipe P1 are connected by a pipe P4, and a damper A3 is provided on the blower W side of the pipe P4.
And the exhaust port w3 is connected to the exhaust port w4 by a damper B4.

Further, the pipe P4 and the damper B3 are connected by a pipe P5, and the damper A4 is provided on the pipe P5.

The foamed resin particles filled and discharged in the storage tank 1 are commonly called pellets and have a diameter of about 6 to 8 mm, and are made of foamed polyethylene or the like and have extremely high heat insulating properties.

Usually, these particles are subjected to antistatic treatment in order to prevent electrostatic charge.

The filling and withdrawing operations of the solar heat utilization apparatus having the above configuration will be described.

First, when the start switch (not shown) of the blower W is turned on,
The switching damper A1 and the dampers A2, A3 and A4 are in the open state. On the other hand, the other dampers B1, B2, B3, B
4 is also interlocked and is closed.

Therefore, when the blower W is driven, the air from the air supply port w2 reaches the air intake port w1 via the pipe P3, and is sent to the storage tank 1 from the discharge port w3 via the pipe P5. Then, the pellets are compressed in the storage tank 1 from above and the pellets are pressure-fed to the feed pipe P1. Next, the pellets sequentially pressure-fed from the feed pipe P1 are the upper portions 21 of the glass shelters 2a, 2b ...
It is thrown in from. When the inside of each of the glass shelters 2a and 2b is filled with pellets, a sensor (not shown) works to stop the drive of the blower W. As a result, the foamed resin particles filled in the glass shelters 2a and 2b form an adiabatic barrier layer, which thermally blocks indoors and outdoors.

Next, when pulling out the pellets from the glass shelters 2a, 2b ..., When a pulling switch (not shown) is turned on, the dampers B1, B2 and B3, B4 are opened. On the other hand, the dampers A2, A3 and A4 are closed. Therefore, the air in the storage tank 1 is sucked from the air intake port w2 of the blower W via the pipe P3 and discharged from the exhaust port w4. Accordingly, the storage tank 1 has a negative pressure. As a result, the pellets in the glass shelters 2a, 2b ...
Return pipes P2a, P because dampers B1, B2 are open
It is pulled out from each lower part 22 via 2b.

In such a state, if the glass shelter 2a is closest to the storage tank 1 and the internal resistance of the return pipe P2 is small, the foamed resin particles in the glass shelter 2a are extracted first and First, the foamed resin particles do not flow. If this state is detected by the sensor S1 and the damper B1 is closed, air is not sucked into the glass shelter 2a, and air is sucked by the blower W with respect to the glass shelter 2b ... Only done. Next, when the foamed resin particles in the glass shelter 2b are exhausted, the damper B2 is closed by the sensor S2, and the pulling-out operation is performed in the same manner thereafter, and a sufficient suction force can be exerted on the last glass shelter 2n.

In order to fill the foamed resin particles in the glass shelters 2a, 2b ... Again, by turning on a storage switch (not shown), the pellets in the storage tank 1 are blown by the blower W in the same manner as described above via the feed pipe P1. It is thrown in from the upper part 21 of 2.

<Effects of the Invention> As described above, the solar heat utilization apparatus of the present invention does not suck air from the glass shelter that has been completely drawn when the foamed resin particles are drawn from the glass shelter, so that the foamed resin particles are filled. A sufficient suction force can be exerted on the glass shelter that is in use, so that even if the return pipe is far from the storage tank and the internal resistance of the return pipe is large, complete filling and withdrawing operations can be performed without leaving foamed resin particles. It can be performed.
