Air conditioners using pneumatic solar heat collectors that generate warm air using solar heat are increasingly being used. In addition, in such a device, there is a main space that requires comfortable air conditioning such as a living room or children's room, and a secondary space that is not normally air-conditioned such as a hallway, staircase, or entrance, or an indoor space such as a living room or children's room. In some cases, such as in a heat storage tank that stores hot air for heating at night, etc., it is necessary to automatically distribute surplus air to another location depending on the amount of hot air needed in one location. be. There are also cases where it is necessary to shut off or fully open the air flow path.

[Purpose of invention]

The present invention is equipped with rotary blades that tilt according to the amount of airflow, and a driving tool that can forcefully tilt the rotary blades, so that hot air can be distributed to other places according to the amount of hot air flowing to one place, and can be distributed as appropriate. The object of the present invention is to provide a metering damper for an air-type solar heat collector that can meet the above requirements by opening and closing hot air.

[Disclosure of invention]

Hereinafter, the metering damper (hereinafter referred to as metering damper) 10 of the pneumatic solar heat collector of the present invention will control the amount of air in the hallway, hand-washing room, entrance, etc. An embodiment of the present invention will be described based on the drawings, taking as an example a case in which the present invention is adopted in an air conditioner 1 that utilizes solar heat and is capable of discharging the surplus warm air into a slave space 4 such as the like.

An air conditioner 1 that uses solar heat connects an air-type solar heat collector 2 in parallel to an indoor main space 3 and a subordinate space 4, and also reduces the amount of hot air blown into the main space 3 and removes the surplus. A metering damper 10 according to the present invention is disposed to blow out warm air of 100% to the slave space 4.

The air-type solar heat collector 2 houses a heat collecting plate 22 that can collect solar heat and heat the air inside the box body 21, which is arranged on a sloped roof and whose upper part is covered with a transparent plate. .

The main space 3 is where family members enter for a relatively long time,
In this example, upstairs and downstairs rooms 3A and 3B, which are living rooms, children's rooms, etc. that require comfortable air conditioning, are treated as the main space 3.

In addition, in subordinate space 4, the presence time of the householder is relatively short,
Although air conditioning is preferable, this is an indoor space that is usually left unconditioned, and in this example, entrance 4A,
A washroom 4B and a hallway 4C are set as secondary spaces 4.

In addition, the pneumatic solar heat collector 2 is provided with an air outlet 23 and an air inlet 24 by cutting out the bottom of the box part 21 at its upper and lower positions.
There are vents 26 provided in the rooms 3A and 3B,
A feeding duct 27 which is open at 26 and has a fan F interposed therebetween is connected thereto.

In addition, the feed duct 27 has an entrance 4A and a washroom 4.
A branch duct 30 equipped with vents 29 .

Therefore, the feed duct 27 and the branch duct 30 are air flow paths 7 that connect the air outlet 23 of the pneumatic solar heat collector 2 to the main space 3 and the sub space 4 in parallel via the fan F. is formed.

Also, the air inlet 24 has rooms 3A, 3B, and entrance 4.
The circulation ducts 33 and 34, which are equipped with vents 32 that open in A, the washroom 4B, and the hallway 4C, are the branch pipes 3.
5.

Further, the branch duct 30 has a rotary blade 11 near the branch point that tilts according to the amount of air;
A metering damper 10 according to the present invention is provided, which includes a driving tool 12 for forcibly driving the damper 10 of the present invention.

As shown in FIG. 4, the metering damper 10 includes a rectangular base cylinder 13 which is provided with connecting flanges at both ends and has a rectangular shape that can cross the base cylinder 13 and substantially shield the base cylinder 13. The plate-shaped rotary blade 11 is supported and attached by the support portion 14. The support portion 14 is a straight shaft body and can protrude from one side wall of the base tube 13.
Further, a biasing tool 15 having a lever 15B to which a weight 15A is fixed in a variable position is attached to the protruding end.

The support portion 14 includes, for example, the cylindrical driving tool 12 which is pivotally connected to the base tube 13 by bosses protruding from both side walls thereof.
By being loosely fitted therein, the driving tool 12 is pivotally supported by the base cylinder 13, and therefore, the driving tool 12 is arranged concentrically with the support section 14.

Further, the rotating blade 11 is fixed to the support part 14 while being deviated upward from the center, and in the vertical state where the lower end of the back surface abuts the protruding piece 13A provided on the lower plate of the base cylinder 13, 13 can be covered inside.

The drive tool 12 is made relatively rotatable by forming cutouts 16, 16 at symmetrical positions into which the protrusion of the rotary blade 11 from the support section 14 is loosely fitted. Furthermore, the opening angle of the notch 16 is set within the tilting angle range of the rotary blade 11 that tilts from the vertical state against the biasing member 15, depending on the air flow rate.

Further, in the standard state, the driving tool 12 has the rotating blade 11
However, the notches 16 are positioned so that they can freely rotate within the tilting angle range from the vertical position. Therefore, as the wind pressure of the wind passing through the base tube 13 increases, the rotating blade 11
It can tilt against its own eccentric load.

Further, as shown in FIG.
The first pushing portion 18A, which is the edge of the rotary blade 11 in this direction, can be opened until the rotating blade 11 is approximately parallel to the central axis of the base tube 13.

Further, by rotating the driving tool 12 in a direction opposite to the tilting direction of the rotary blade 11, the second push portion 18B, which is the edge of the notch portion 16 in this direction, is rotated as shown in FIG. The wings 11 can be forcibly tilted to a vertical position that closes the base cylinder 13. Moreover, by separating the gap formed by the notch 16 between the first and second pushing parts 18A and 18B, when the notch 16 faces downward, the rotary blade 11 can be moved as described above.
can be freely tilted within the tilting angle range defined by the notch 16 from the vertical state.

The drive tool 12 protrudes from the other side wall, and a rotating means 19 consisting of a reduction motor is attached to the protruding end. As the rotation means 19, in addition to those that can be operated remotely, such as a cylinder and a solenoid, it is also possible to use ones that can be operated manually, such as a lever.

Further, as shown in FIG. 8, the metering damper 10 has a driving tool 12 formed in the shape of a straight shaft, and a support section 14 that is fitted over the driving tool 12 and is also formed as a cylinder having a notch 16. In addition, the pushing part 18 has the first and second
The pushing portion can also be formed by a single projecting piece that contacts both end edges of the notch portion 16 on both sides and projects from the drive tool 12.

Further, in this case, the support part 14 may be formed in a ring shape and configured to be supported on the driving tool 12 at an appropriate position.

The metering damper 10 is installed so that the tilting direction of the rotating tool 11 is directed toward the downstream side of the branch duct 30.

A damper 28 is attached to the vent 26, which can close the vent 26 and adjust its opening area.

Further, as the fan F, a relatively inexpensive quantitative fan that discharges a fixed amount of air is used.

[Effect]

The weight of the weight 15A of the biasing tool 15 and the mounting position on the lever 15B are adjusted, and the ventilation holes 26, 2 are adjusted.
6 is fully opened, the metering damper 10
is set so that the rotating tool 11 comes into contact with the protruding piece 13A and closes the air flow path 7 passing through the branch duct 30.

Therefore, during the winter solar radiation, when both the rooms 3A and 3B are used and the vents 26 and 26 are fully opened, as shown in FIG. is sealed.

On the other hand, as shown in FIG. 3, when the vent 26 of the room 3B is tilted or closed in the direction in which the damper 28 is closed, the resistance of the feed duct 27 increases, and therefore the wind pressure acting on the metering damper 10 increases. By doing so, the rotating blade 11 is tilted. Therefore, the branch duct 30 can be opened and the surplus hot air from the pneumatic solar heat collector 2 can be blown out into the slave space 4 .

If necessary, the resistance of the rotary blades 11 to the branch duct 30 can be significantly reduced by making the rotary blades 11 horizontal as shown in FIG. 6 using the driving tool 12. Moreover, the branch duct 30 can also be closed.

Note that the eccentric load of the rotating blade 11 and the biasing tool 15
This forms a main biasing stage that urges the rotary blade 11 in a direction that brings the rotating blade 11 into contact with the protruding piece 13A to close the air flow path. However, when the eccentric load is large, the biasing tool 15 is It may be omitted, or the weight 15A may be attached to the rotary blade 11.

Further, the metering damper 10 of the present invention is shown in FIG.
Air conditioner 1A that uses solar heat and includes a heat storage tank 9
It can also be used for

The device 1A connects the air outlet 23 of the pneumatic solar heat collector 2 with a feed duct 27 with a fan F and a damper D1 interposed therebetween to the heat storage tank 9 via the metering damper 10 according to the present invention. There is. Also, feeding duct 2
7 is electrically connected to the room R via the damper D2, and the metering damper 10 is connected to the auxiliary fan F1.
A bypass duct 40 is connected in parallel with the damper D3 and the damper D3. Note that a circulation duct 33 extending from the air inlet 24 is connected to the room R and the heat storage tank 9.

In such a device 1A, warm air is discharged into the room R by fully opening the damper D1 and opening the damper D2 only by a necessary amount. Also metering damper 10
In response to wind pressure that reduces the amount of hot air flowing out to the damper D2, the rotary blades 11 tilt, supplying surplus hot air to the heat storage tank 9 and storing heat therein. In addition, heat storage tank 9
opens the dampers D3 and D2 and opens the auxiliary fan F1.
The stored heat can be taken out to the room R by driving the .

Further, the metering damper 10 drives the driving tool 12, and the sixth
By tilting the rotary blades 11 to the open state shown in the figure and opening only the damper D1, the entire amount is fed to the heat storage tank 9. Also, the metering damper 1 is controlled by the rotary blade 11.
0 and open only the dampers D1 and D2, it is also possible to discharge the entire amount of warm air into the room R.

Therefore, when supplying hot air only to the heat storage tank 9, the flow resistance can be reduced by flipping up the rotary blades 11.

[Effect of idea]

In this way, the metering damper of the present invention consists of rotary blades that are arranged in the air flow path into which warm air from the pneumatic solar collector is blown, and that tilt according to the volume of the hot air; Since it is equipped with a drive device that can tilt between open and closed states, it can be used in main spaces such as living rooms, hallways,
Depending on the volume of hot air blown into an air-conditioned area, such as a secondary space such as a washroom, a room, or a heat storage tank, it can be used to discharge the excess air volume to other areas, increasing the efficiency of hot air usage and discharging it as appropriate. Close the air flow path,
It can be opened, and therefore the device can be simplified compared to the case where rotating blades and switches are used together, reducing device cost and improving workability.
