Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window unit having not only a lighting function but also a heat insulating / shading function depending on whether or not resin particles are filled in a filling space between opposed inner and outer sashes.

[0002]

2. Description of the Related Art Conventionally, as this type of window unit, for example, a unit described in Japanese Patent Publication No. 7-59870 is known. This window unit constitutes a filling space between a pair of transparent plates opposed to each other, and in this filling space, spherical resin particles are freely dropped from a storage tank to be filled, and the filled resin particles are sucked by a suction device. The lower end of the filling space is configured to be suction-collected to the storage tank via the collection passage.

In this case, the suction device is provided in the storage tank, and the recovery passage extends from the lower side of the filling space to the storage tank through the left side. The bottom plate that defines the lower end of the filling space has a plurality of recovery ports connected to the recovery passage, while the storage tank has an introduction port connected to the recovery passage. When the suction device is driven, the pressure in the storage tank is reduced, and the resin particles in the filling space are sucked into the storage tank from the inlet through the recovery port and the recovery path.

[0004]

In such a conventional window unit, since resin particles are sucked from one side of the storage tank, the resin particles are unevenly accumulated in the storage tank on the left and right sides. Specifically, many resin particles accumulate near the suction device. In this way, if the resin particles accumulate unevenly on the left and right, when the resin particles are dropped freely, even if the suction device side is full in the filling space, there is a shortage of resin particles on the introduction port side and a space is generated. I will. Further, since the collection passage is formed on one side of the transparent plate, the design of the unit as a whole is poorly balanced.

It is an object of the present invention to provide a window unit in which collected resin particles are uniformly accumulated in a storage tank in the left and right directions without impairing the design of the entire unit.

[0006]

The window unit of the present invention comprises:
The resin particles filled by the free fall into the filling space between the inner and outer turrets arranged opposite to each other are sucked from the lower end of the filling space and guided to the storage tank arranged above the filling space, so that the inside of the filling space is filled. In the window unit for collecting the resin particles, a pair of recovery ports facing the lower left and right ends of the filling space, a pair of inlets formed in the left and right side plates of the storage tank, and disposed on the left and right sides of the filling space, A pair of collection passages having one end communicating with each collection port and the other end communicating with each introduction port,
A suction device that communicates with a suction port formed at the left and right intermediate portion of the storage tank and suctions resin particles in the filling space into the storage tank through both the recovery ports, both the recovery passages, and both the introduction ports; It is characterized by.

[0007] According to this configuration, when the suction device is driven, the pressure in the storage tank is reduced, and the resin particles in the filling space are divided into left and right sides from the one filled at the lower end, and the collecting port, the collecting passage, and the introducing port. Through the storage tank. In this case, in the storage tank, the resin particles are introduced from the left and right inlets, so that the resin particles are relatively uniformly accumulated (accumulate) in the storage tank in the left-right direction. In addition, since the collection passages are provided on the left and right sides of the filling space, the left and right balance of the unit itself is not impaired in design. Furthermore, since the resin particles are separated and collected on the left and right, it is not always necessary to provide a suction passage on the lower side.

In this case, it is preferable that the suction device is constituted by a single blower.

According to this configuration, even if the structure is such that the resin particles are sucked and collected by two systems on the left and right sides, it is possible to suppress an increase in cost.

In these cases, in the storage tank, the introduction port and the suction port are arranged so as not to face each other.
preferable.

According to this configuration, in the storage tank, the suction air serving as a medium for transporting the resin particles flows from the inlet to the suction port, but the inlet and the suction port are arranged in a non-opposed state. Therefore, the suction air tends to be turbulent. For this reason, the resin particles transported by the suction air fall relatively widely, and are uniformly distributed in the storage tank. Therefore, the resin particles are uniformly accumulated in the storage tank in the left-right direction.

In these cases, the left and right middle portions of the storage tank are formed with a recessed portion that is recessed in the front-rear direction.
preferable.

According to this configuration, the resin particles are relatively easy to accumulate in the left and right intermediate portions of the storage tank where the suction port of the suction device is located, but are quantitatively regulated by the recessed portions. Accumulates uniformly in the storage tank in the left-right direction. In addition, a suction device and its suction duct can be provided in the recess.

An inclined plate 49 is provided above a part of the outer lower frame 22b that defines the lower end of the filling space 4.
Are arranged.

The filling means 5 is provided above the fitting window 2 and is provided at a boundary between the storage tank 10 and the filling space 4. A shutter 11 is provided, and a shutter opening / closing mechanism 12 for opening and closing the shutter 11 is provided. And
The shutter opening / closing mechanism 12 is disposed in a space below the storage tank 10 in the tank cover 8.

As shown in FIG. 4 and FIG.
1 is a fixed plate 51 configured as a part of the outer upper frame 21b as a portion corresponding to the top plate of the filling space 4 described above, a movable plate 52 disposed above the fixed plate 51,
It comprises a movable plate 52 and a connecting plate 53 for connecting the shutter opening / closing mechanism 12. Above the fixed plate 51, a pair of side plates (part of the outer upper frame 21b) 54, 54 connected to the lower end of the storage tank 10 are provided.
The depth around the shutter 11 is regulated by the pair of side plates 54. The movable plate 52 is mounted between the pair of side plates 54, and slides on the fixed plate 51 in the left-right direction to open and close.

The connecting plate 53 has a base end at the movable plate 52.
And is connected to the shutter opening / closing mechanism 12 through a slit 55 formed in the front side plate 54 (see FIG. 6). The slit 55 extends in the left-right direction, and the connecting plate 53 reciprocates along the slit 55 with the opening / closing operation of the shutter opening / closing mechanism 12.

The movable plate 52 includes an upper plate portion 52a and a pair of side plate portions 52b which are suspended from both ends of the upper plate portion 52a.
52b, the upper plate (upper plate) 52a is larger than the diameter of the resin particles A and is separated from the fixed plate (lower plate) 51. In the upper plate portion 52a of the movable plate 52, a plurality of upper drop openings 56 are formed at equal intervals.
Numeral 6 has the same shape, and is formed in a rectangular shape over the entire width before and after the upper plate portion 52a. Further, on the lower surface of the upper plate portion 52a, fin members 58 are vertically provided via holding members 57 at left and right opening edges forming the respective upper drop openings 56. The holding member 57 is formed in a substantially “C” -shaped cross section, and is fixed to the lower surface of the upper plate portion 52a in a downward state. The fin member 58 is formed of a flexible member such as rubber or soft resin and has a substantially “T” -shaped cross section. The fin member 58 has a length inscribed in the front-back direction with the movable plate 52, is held by the holding member 57 at the upper end, and slides on the upper surface of the fixed plate 51 at the lower end.

The fixed plate 51 also has a movable plate 52
Similarly, a plurality of lower drop openings 59 are formed at equal intervals, and each upper drop opening 59 is formed in a square and the same shape. In this case, the lower drop opening 59 is formed somewhat longer in the sliding direction (left-right direction) than the upper drop opening 56 (see FIG. 5), so that the resin particles A fall smoothly. . The movable plate 52 with respect to the fixed plate 51
The lower drop opening 59 and the upper drop opening 56 are completely displaced from each other in an open position (FIG. 5A) where the left and right centers of the upper drop openings 56 coincide with each other. It reciprocates (opens and closes) with the closed position (FIG. 5C). In the open position, the storage tank 10 and the filling space 4 communicate with each other through the upper drop openings 56 and the lower drop openings 59, and the resin particles A are allowed to fall. The filling space 4 is closed and the falling of the resin particles A is prevented.

In the upper plate portion 52a of the movable plate 52, the length in the left-right direction of each upper drop opening 56 is formed slightly shorter than the length between adjacent upper drop openings 56. Similarly, the length in the left-right direction of each lower drop opening 59 is formed slightly shorter than the length between adjacent lower drop openings 59. Therefore, as shown in FIG. 5, when the movable plate 52 is moved to the open position, the fin member 58 is in contact with the opening edge of the fixed plate 51 and guides the resin particles A to drop ( FIG. Similarly, when the movable plate 52 is moved to the closed position, the fin member 58 is in contact with the opening edge of the fixed plate 51 and the resin particles A
Is prevented from falling to the lower drop opening 59 side (FIG. 3 (c)).

Here, the opening / closing operation of the shutter 11 will be briefly described with reference to FIG. When the movable plate 52 moves in the opening direction indicated by the arrow in the drawing from the closed state (closed position) in FIG. 9C, the resin particles A between the movable plate 52 and the fixed plate 51 are pushed by the fin members 58. , And falls from the lower drop opening 59. at the same time,
The upper drop opening 56 faces directly above the lower drop opening 59, and the lower drop opening 59 and the upper drop opening 56 match as shown in FIG. Of course, this opening operation is performed instantaneously. When the lower drop opening 59 and the upper drop opening 56 match, the storage tank 10 and the filling space 4 communicate vertically, and
The resin particles A in the storage tank 10 fall freely into the filling space 4 by their own weight.

By the way, since the fin member 58 is formed of a member having flexibility, in the opening operation, the resin particles A between the movable plate 52 and the fixed plate 51 are pushed in a sweeping manner. At this time, the resin particles A are
The fin member 58 is appropriately curved to avoid being pinched between the lower end of the fixing plate 51 and the upper surface of the fixed plate 51. Further, even if this state cannot be avoided and the resin particles A wrap around to the back side of the fin member 58 (FIG. 9A), the resin particles A fall from the lower drop opening 59 by the subsequent closing operation (FIG. 9A). (B)).

On the other hand, the open state (open position) of FIG.
Then, when the movable plate 52 moves in the closing direction indicated by the arrow in the figure, the upper drop opening 56 is displaced with respect to the lower drop opening 59 (FIG. 6 (b)). 51 comes into contact with the edge of the opening to be in a closed state. In this state, each fin member 58 prevents the resin particles A from falling.

As described above, the upper plate 5 of the movable plate 52
2a and the fixing plate 51 are spaced apart from each other,
Since the fin members 58 are provided on the lower surface of the movable plate 52 on both sides of the upper drop opening 56, the resin particles A are formed between the fin members 58 and the fixed plate 51 with the opening and closing operation of the shutter 11. Even if the resin particles A are pinched, the resin particles A are not pinched between the upper plate portion 52a of the movable plate 52 and the fixed plate 51 or between the upper drop opening 56 and the lower drop opening 59. Therefore, poor opening / closing of the shutter 11 and a locked state can be avoided. In this embodiment, the movable plate 52 is provided above the fixed plate 51.
Is disposed, but it may be disposed on the lower side. In such a case, it goes without saying that the fin member 58 is attached to the lower side of the fixed plate 51. The shape of the upper and lower drop openings 56 and 59 may be oval, circular, or the like.

As shown in FIG. 6, the shutter opening / closing mechanism 12
The opening operation solenoid 62 and the closing operation solenoid 63 are disposed on the support plate 61 in the opening and closing direction of the shutter 11, and the opening operation link 64 connected to the plungers 62a and 63a of the solenoids 62 and 63, respectively.
And a closing operation link 65, and both links 6
The distal ends of the connecting plates 4 and 65 are rotatably attached to the lower surface of the connecting plate 53 via brackets 66. The two solenoids 62 and 63 are connected to the control means 7. When the open operation solenoid 62 is excited by the control signal from the control means 7 while the closing operation solenoid 63 is demagnetized,
The opening operation link 64 is pulled, and the shutter 11 is opened,
Conversely, when the closing operation solenoid 63 is excited while the opening operation solenoid 62 is demagnetized, the closing operation link 65 is pulled and the shutter 11 is closed.

Since the closing state of the shutter 11 is in a steady state, the closing operation solenoid 63 and the closing operation link 65 may be replaced by an urging means such as a spring.
On the other hand, the timing for closing the shutter 11 that has been opened is when the resin particles A are completely filled in the filling space. This timing measures the average time during which the resin particles A are filled in the filling space. The timer control may be performed in consideration of the safety factor, or the filling of the resin particles A may be detected and controlled by a sensor or the like. However, the automatic closing operation and the manual closing operation may be switched, and the shutter 11 may be manually closed. In such a case, the filling of the resin particles A is stopped halfway, so that the awning of the fitting window 2 can be adjusted.

On the other hand, an open detection switch 67 for detecting the fully open state of the shutter 11 is provided on the side of the open operation solenoid 62 and a completely closed state of the shutter 11 is provided on the side of the close operation solenoid 63 with the reciprocating connecting plate 53 interposed therebetween. Are respectively provided. The two detection switches 67, 68 are connected to the control means 7,
If the opening detection switch 67 is not turned on by the opening operation of the opening operation solenoid 62 as a trigger, the opening operation solenoid 62 is opened again, and the closing operation of the closing operation solenoid 63 is used as a trigger to turn off the closing detection switch 68. Causes the closing operation solenoid 63 to close again.

Thus, it is possible to avoid a state in which the shutter 11 does not completely open and close due to some trouble. It is preferable that the restart operation and the reclosing operation are repeated until each of the detection switches 67 and 68 is turned on. However, the number of times of this re-operation is counted, and when the count value exceeds a predetermined number, the operation is performed. May be stopped and an alarm may be issued. The detection switch 6
Instead of 7, 68, an optical sensor such as a photo interrupter may be used.

As shown in FIG. 7, the storage tank 10 constituting the recovery means 6 is composed of a main storage portion 71 protruding forward and a drop introduction portion 72 connected to the lower side of the main storage portion 71. . The depth dimension before and after the drop introduction part 72 is formed to be substantially the same as the depth dimension before and after the filling space 4, and the left and right width dimensions are formed to be substantially the same as the left and right width dimensions of the filling space 4. I have. Thereby, the storage tank 10
The inside resin particles A can be smoothly guided to the filling space 4. The bottom plate 73 constituting the main storage section 71 is inclined downward toward the drop introduction section 72, and
The resin particles A inside can be smoothly guided to the drop introduction section 72.

At the intermediate position of the storage tank 10, the recess 7
The suction device 14 is provided in the recess 74. In addition, a suction port 76 connected to the suction device 14 is formed in an upper part of the front plate 75 constituting the recess 74. On the other hand, the upper ends of the left and right side plates 77, 77 of the storage tank 10 are respectively provided with the above-mentioned collection passages 13
Are formed. That is, the suction port 76 opens rearward, and the two introduction ports 78,
Numerals 78 open in the left-right direction.

In the collecting operation for collecting the resin particles A in the storage tank 10, the suction device 14 is driven with the shutter 11 closed. When the suction device 14 is driven, air in the storage tank 10 is sucked through the suction port 76,
The pressure inside the storage tank 10 becomes negative. When the pressure inside the storage tank 10 becomes negative, the air in the filling space 4 flows into the storage tank 10 through both the inlets 78, 78, and is conveyed by the air so that the resin particles A are stored in the storage tank 10 It is sucked in.

As shown in FIG. 1 and FIG.
Numeral 3 is formed inside rectangular hollow members 27, 27 arranged on both sides of the filling space 4, respectively. Each collection passage 13
The upstream end (lower end) communicates with the lower end of the filling space 4 via a recovery port 79 formed in each square hollow member 27, and the downstream end (upper end) communicates with the above-described introduction port 78. To the upper end of the storage tank 10. That is, the left and right sides of the lower end of the filling space 4 and the left and right sides of the upper end of the storage tank 10 communicate with the collection passages 13 and 13, respectively.
The resin particles are separated into right and left from the lower end of the filling space 4 and sucked into the storage tank 10.

On the other hand, as shown in FIGS. 1 and 7, the suction device 14 includes a blower 81 disposed in the space below the storage tank 10 inside the tank cover 8, and the suction port 76 and the blower 81. And the suction duct 82 is disposed so as to fit into the recess 74 of the storage tank 10. Suction duct 82
Is connected to the control means 7 and the control means 7
N-OFF control is performed. The suction port 76 has a net 8 to prevent the resin particles A from being sucked into the blower 81.
0 is provided.

Here, referring to FIGS. 1 and 7,
The operation of collecting the resin particles A will be briefly described. When the suction device 14 is driven from the state in which the filling space 4 is filled with the resin particles A and the shutter 11 is closed, the air in the filling space A is simultaneously sucked into the left and right collection passages 13 and 13. Riding, the resin particles A are guided to the storage tank 10.
At this time, the two inlets 78, 78 and the suction port 76 are arranged in a non-opposed state, and the recess 74 becomes an obstacle, so that the air flow in the storage tank 10 becomes turbulent, and the respective inlets 78 Are transported toward the suction port 76. Moreover, the resin particles A have two inlets 7.
Since it flows into the storage tank 10 from 8, 78, it accumulates uniformly in the storage tank 10.

That is, the collected resin particles A are accumulated and stored in the storage tank 10 at substantially the same level in the left-right direction. Therefore, when the shutter 11 is opened and the resin particles A are dropped into the filling space 4 from this state, the resin particles A are uniformly reduced in the right and left directions and are uniformly dropped in the left and right directions.
Therefore, the filling space 4 is uniformly filled with the resin particles A in the left and right directions, and finally the filling state is such that no gap is formed in the upper part.

Since the resin particles A in the filling space 4 are separated into right and left parts and are simultaneously collected, the resin particles A can be collected in a short time. However, for that purpose, the collection passages 13 are required on the left and right sides of the filling space 4, whereby the design balance on the left and right sides of the window frame 9 itself is good, and the width of each vertical frame 23 is extremely wide. Nothing.

When the resin particles A are collected on the corn, the resin particles A are conveyed by air. However, the resin particles A are smoothly collected without leaving the resin particles A in the filling space 4. Therefore, it is essential to create a good air flow in the filling space 4. Therefore, as shown in FIGS. 8 and 9, in this embodiment, the upper ventilation port 47 is formed by utilizing the gap between the upper frame 42 of the outer shroud 3 b and the outer upper frame 21 b of the window frame 9. Is composed. Further, a plurality of lower ventilation holes 48 are formed in the lower frame 43 of the outer sash 3b so as to positively generate air flow also at the lower end of the filling space 4. Further, by utilizing the weight of the resin particles A, the resin particles A can be smoothly guided to the two recovery ports 79, 79 on a part of the outer lower frame 22 b defining the lower end of the filling space 4. Is provided with an inclined plate 49.

The upper vent 47 is open to the outside air and corresponds to the left and right widths of the upper end of the filling space 4. I do. For this reason, the air flows uniformly downward in the left-right direction, and the resin particles A decrease uniformly in the left-right direction. At this time, since the lower vent 48 is appropriately closed by the resin particles A filled in the lower part of the filling space 4, the inflow of air from the lower vent 48 is suppressed.

Each lower vent 48 is provided with a lower frame 43 of the outer shoji 3b.
And a communication hole 48b formed in the partition plate of the lower frame 43. The main lower ventilation port 48a communicates with the communication port 48b through the hollow portion of the lower frame 43, and the communication port 48a
b is open to the outside air. When the resin particles A are reduced to the level of the main lower vents 48a at the time of recovery, air flows in from the main lower vents 48a. In this state, the remaining amount of the resin particles A is considerably small, and the resin particles A are sucked into the recovery port 79 by the air from the main lower vents 48a while fluttering. In the state where the air flows in from the lower ventilation port 48, the air is in a short circuit state, so that the flow of the air from the upper ventilation port 47 is extremely small.

The inclined plate 49 is formed in a chevron shape, with the left half inclined toward the left collecting port 79 and the right half inclined toward the right collecting port. When collecting, the inclined plate 49
The upper resin particle A is inclined by the weight of the resin particle A from the upper side.
And are pushed out by the left and right recovery ports 79, 79. In the final stage of the recovery, the air is rolled on the inclined plate 49 while being swept by the air from the lower ventilation port 48 and is sucked into the recovery port 79.

As described above, until the final stage of recovery, air mainly flows in from the upper vent 47, and in the final stage, air mainly flows in from the lower vent 48. Therefore, the resin particles A are smoothly transported, and the resin particles A do not remain in the filling space 4. In particular, the resin particles A do not remain even in the left and right intermediate portions of the filling space 4 where the resin particles A are likely to remain due to the interaction between the lower vent 48 and the inclined plate 49. Further, since the filling space 4 is always in communication with the outside air through the upper ventilation port 47 and the lower ventilation port 48, the filling space 4
No dew condensation occurs on the members defining the above. Note that, in the plurality of lower vents 48, it is preferable that the lower vent 48 in the middle portion between the left and right of the filling space 4 in which the resin particles A easily remain is formed larger than the lower vents 48 in other parts. The shape of the lower ventilation port 48 may be circular or elliptical.

As shown in FIG. 1, the control means 7 comprises a control device main body 91 composed of a CPU and the like built in a control box 92, and a controller 93 connected thereto. The storage tank 10 is disposed inside the tank cover 8 in a space below the storage tank 10. The controller 93 is provided with push buttons for “fill” and “collect”, and the shutter open / close mechanism 12 and the suction device 14 are operated by the controller 93. When the suction device 14 is driven to collect the resin particles A from the filling space 4, the storage tank 10
Air flows in slightly. For this reason, the shutter 11
When the suction device 14 is stopped, the resin particles A fall down the filling space 4 and remain at the lower end when the suction device 14 stops. Therefore, it is preferable that the suction device 14 be restarted for a short time by timer control.
