It has a structure that transmits to rotatably supported plate-shaped movable parts such as louvers and dampers. Then, by the transmitted driving force, the inclination of each component is changed to change the blowing direction (up and down, left and right) of the blown air blown from the blowout port, and the suction air is efficiently sucked in from the suction port. Or change the amount of air blown through the air duct.

[0005]

However, these conventional fluid control devices are all mechanical drive structures for transmitting external power to a movable part through a transmission mechanism, so that the number of parts is considerably high. Was required, and the structure was complicated. In addition, there is a drawback that the ventilation resistance is large when changing the wind direction.

The present invention has been made in view of such circumstances, and an object thereof is to reduce fluid flow and ventilation resistance with a simple structure which does not require a drive source and a transmission mechanism. Another object of the present invention is to provide a fluid control device which can be changed and is excellent in small size and light weight.

[0007]

In order to achieve the above object, a fluid control device according to a first aspect of the present invention opens and closes the flow passage with one end fixed and the other end free end in the flow passage through which the fluid flows. Direction, the plate-like polymer gel actuator that can be bent in a direction that opens and closes the flow passage according to an applied electric field, and a power supply voltage to the polymer gel actuator to supply the high voltage. The molecular gel actuator is provided with an application unit for applying an electric field and a unit for operating the application unit.

It is possible to control the flow of fluid. Moreover, since the polymer gel actuator bends smoothly, the ventilation resistance when changing the flow of fluid is reduced. According to the fluid control device of the second aspect, due to the bending deformation of the polymer gel actuator, the polymer gel actuator itself becomes a kind of outlet louver. Thereby, the wind direction of the blown air can be changed. According to the fluid control device of the third aspect, due to the bending deformation of the polymer gel actuator, the polymer gel actuator itself becomes a kind of inlet louver. This makes it possible to efficiently suck in the intake air.

According to a fifth aspect of the fluid control device, the polymer gel has a bending amount according to the direction and strength of the applied electric field, and the free end side opens and closes the flow passage with the fixed side as a fulcrum. It causes a bending movement while drawing a smooth curve.

According to the fluid control device of the sixth aspect,
It is possible to set a curved curved surface for each polymer gel actuator. In other words, it is possible to perform bending that cannot be obtained by one polymer gel actuator, for example, bending motion that draws different curved surfaces for each polymer gel actuator. This increases the degree of freedom of the curved surface shape of the polymer gel actuator. According to the fluid control device of the seventh aspect, it is possible to prevent unnecessary exposure in the portion of the polymer gel actuator to which the power supply voltage is supplied.

A fan casing 4 in which the blow-out passage 3a is extended
At the inner portion, an indoor fan 6 configured by a cross flow fan is provided along the left-right direction. The right end of the indoor fan 6 is connected to an output shaft of a fan motor 6a installed in a device accommodating chamber (not shown) located between the right side wall of the air passage 4 and the right side wall of the main body 1. . by this,
By operating the fan motor 6a, the air in the room is sucked through the suction ports 2a and 2b and blown out into the room through the air outlet 3.

Further, each of the first and second suction ports 2a, 2b
On the further downstream side, an indoor heat exchanger 7 that is bent in a substantially V shape is provided so as to face the opening, and heat is exchanged with the indoor air flowing through the air passage 5.

A front opening type suction louver 8, 8 composed of, for example, two strip-shaped plates is provided between both end edges of the first suction port 2a.
Is rotatably supported. The suction louvers 8 and 8 close the first suction port 2a when the indoor unit is not operated, and open the first suction port 2a when the indoor unit is operated to guide the suction air. Is done.

A large number of left and right louvers 9, which are connected to each other by synchronizing links (not shown), are arranged side by side in the longitudinal direction on the indoor fan 6 side of the outlet passage 3a. Each of the left and right louvers 9 is rotatably supported by the end wall of the blowout passage 3a, and the turning direction of the left and right louvers 9 can change the blowing direction of the outlet 3 in the left and right directions.

At the air outlet 3 on the opposite side, as shown in FIG. 2, two upper and lower louvers 10, 10 composed of, for example, strip-shaped blades are arranged in parallel in the vertical direction in two stages. However, the blowing direction of the outlet 3 can be changed in the vertical direction. The present invention is applied to these upper and lower louvers 10, 10.

That is, each of the upper and lower louvers 10, 10 comprises a polymer gel actuator 10a. In particular,
This polymer gel actuator 10a is a gel part 1 that, when an electric field is applied, is stimulated by the electric field to cause a bending motion.
It is composed of 0b.

The bending motion of the gel part 10b utilizes the electric response of the polymer gel. That is, sodium acrylate-acrylamide copolymer gel (hereinafter referred to as P
When a direct current electric field is applied by arranging (referred to as AA gel) a rod shape in parallel between the pair of electrodes and by applying a DC electric field, the PAA gel exhibits a characteristic of bending. FIG. 1 shows such a gel part 10b (polymer gel actuator 10).
The structure of the upper and lower louvers 10 constructed in a) is shown.

Explaining the gel part 10b,
In FIG. 1, reference numeral 11 is a strip-shaped polymer gel. For the polymer gel 11, for example, a PVA-PAA gel is used as an electric field-flexible gel having high mechanical strength.
PVA-PAA gel is a water solution in which completely saponified polyvinyl alcohol and linear polyacrylic acid are dissolved.
It is prepared by repeatedly freezing and thawing a DMSO mixed solution. 12 is this strip-shaped PVA
-A pair of parallel electrodes arranged on both sides of the PAA gel in close proximity to the side surfaces.

The entire periphery of the PVA-PAA gel is covered with a PVA gel 13 containing sodium carbonate and water as an electrolytic substance so as to embed these parallel electrodes 12, 12.

As a result, the parallel electrodes 12, 12 and the PVA
-The electrolyte portion 14 is configured between each side of the PAA gel. At the same time, the entire parallel electrodes 12, 12 to which the power supply voltage is applied are covered with an insulating material (PVA gel 13).

PVA-PAA prepared by PVA gel 13
Due to the wrapping of the gel, the gel component 10 as shown in FIG.
b is formed in an outer shape suitable for changing the wind direction in the vertical direction, for example, a band plate having a wing-shaped cross section, and constitutes a main body of the vertical louver 10.

The gel part 10b (polymer gel actuator 10a) thus constructed is supple like a living body, and when an electric field is applied from the parallel electrodes 12 and 12, the structure shown in FIG.
As indicated by the two-dot chain line, the characteristic of bending in the thickness direction by drawing a smooth curved surface with the same curvature is exhibited.

As shown in FIG. 2, the gel part 10b is arranged laterally along the blowing direction, for example.
Of the two widthwise ends of the gel part 10b, one end facing the indoor fan 6 side is fixed to the blowout air passage 3a by the support tools 15, 15 and the other end is a free end.

As a result, the gel part 10b is bent in the air in the vertical direction (corresponding to the direction of opening and closing the flow passage of the present application) of the air outlet 3 with the fixed side as a fulcrum in the air as the electric field is applied. It is possible.

Then, this gel component 10bb parallel electrode 1
A direct current variable power source 16 (corresponding to an applying means of the present application) installed in the equipment accommodating chamber together with the fan motors 2 and 12 is connected to the polymer gel actuator 10.
A DC electric field of various voltages can be applied to a.

The DC variable power source 16 is connected to an operating section 18 (both correspond to a means for operating an applying means) via a controller 17. The controller 17 is provided in advance with PVA-PAA corresponding to each wind direction in the vertical direction.
The function to change the direction of DC electric field (direction of polarity of applied voltage) and strength required to bend the gel is set. That is, the bending amount of the PVA-PAA gel can be adjusted.

As a result, the gel part 10a can be bent and deformed in accordance with the set wind direction from the operation section 18. That is, it functions as the upper and lower louvers 10 (exit louvers).

In the indoor unit thus constructed, however, when the vertical air direction is changed, for example, when horizontal blowing is changed to downward blowing, the operating unit 18 is set to downward blowing.

Then, the control signal is output from the controller 17 to the variable DC power supply 16 according to the wind direction, and the parallel electrodes 1
A DC voltage having a direction and strength corresponding to the set wind direction is applied to Nos. 2 and 12. Horizontally oriented PVA-PA
The A gel causes a downward bending motion as indicated by the chain double-dashed line in FIG. 2 according to the applied DC electric field.

That is, in each PVA-PAA gel, the free end side of the tip side bends downward in a smooth curve with the fixed side as a fulcrum, forming a curved surface suitable for downward blowing. At this time, each part of each PVA-PAA gel moves precisely according to the DC electric field. Then, the gel part 1
0b changes from a shape suitable for horizontal blowing to a shape suitable for downward blowing. Following the shape of this gel part 10b,
Cold air and hot air that have passed through the indoor heat exchanger 7 blown out from the blowout port 3 are blown downward. Thus, the polymer gel actuator 10a which itself deforms only by an electric signal,
With 10a, it is possible to change the vertical wind direction of the blown air.

Therefore, it is possible to control the flow of blown air (fluid) with a simple structure that does not require a motor or link mechanism that causes problems such as complexity, size, and weight, and that requires a minimum number of parts. You can

Moreover, the polymer gel actuator 10a
According to the upper and lower louvers 10 configured as described above, it is possible to prevent a problem caused by an increase in ventilation resistance, which is a problem in the conventional louver structure for rotating a flat plate louver.

That is, in the conventional louver that changes the wind direction by rotating the flat plate, the flat plate only tilts, so that depending on the direction, the air flow resistance is increased, which leads to a reduction in the air volume, and the air-conditioning capacity decreases as well as the air-conditioning capacity. This causes a reduction in the warm air reach during heating operation, but the gel part 10
According to the upper and lower louvers 10 configured by b, the smooth curved surface shape can be changed according to the situation, so that unnecessary increase in ventilation resistance can be prevented. Moreover, the link mechanism for transmitting the driving force to the louver is in the air passage and has ventilation resistance. However, since the link mechanism is unnecessary, the ventilation resistance is also eliminated.

Further, the polymer gel actuator 10a
Since the whole is covered with an insulating material, dust in the air does not adhere to the surface of the polymer gel actuator 10a due to charging. FIG. 4 shows a second embodiment of the present invention.

This embodiment is a modification of the first embodiment, in which the parallel electrodes 12, 12 constituting the upper and lower louvers 10 are not entirely insulated, but a part of the parallel electrodes 12, 12 is insulated. Is.

Specifically, the parallel electrodes 12 made of PVA gel,
In order to prevent the parallel electrode 12 from being exposed, the gel part 10b is formed so as not to cover 12 and the insulator 20 made of an insulating material such as plastic is inserted into the tip part (end part on the free side) of the gel part 10b. It is intended to surely insulate the tip portion of the gel part 10b, which is considered necessary, and to increase the strength. FIG. 5 shows a third embodiment of the present invention.

This embodiment is a modification of the first embodiment, and is not a single gel part but a plurality of gel parts 10x, 10y,
10z is connected in series to form a polymer gel actuator 10a having a function as an upper and lower louver (exit louver).

Specifically, the polymer gel actuator 10a includes three gel parts 10x to 10z in the blowout path 3a via an insulating connector 22 (insulating portion) made of, for example, plastic. It has a structure connected along the blowing direction. And these gel parts 10x-1
With the controller 17 connected to 0z, each gel part 10
The b is independently bent. Here, in such a combination of a plurality of gel parts 10x to 10z, a curved curved surface can be set for each gel part 10x to 10z.

That is, it is possible to perform a bending motion which cannot be obtained by one gel part 10b, for example, a bending motion in which a different curved surface is drawn for each gel part 10x to 10z. In particular,
The gel part 10z on the fixed side (right side) and the gel part 10x on the free end as shown by the chain double-dashed line in FIG. 5 are planes, and only the middle gel part 10y is curved, such as a plane and a curved surface. Bending in combination with is possible. That is,
Polymer gel actuator 10 with a high degree of freedom of bending movement
a is obtained.

Therefore, this polymer gel actuator 1
According to the upper and lower louvers 10 composed of 0a, it is possible to obtain a high wind direction conversion characteristic, which the upper and lower louvers 10 using one gel part 10b do not have. FIG. 6 shows a fourth embodiment of the present invention.
An example of is shown. In the present embodiment, the present invention is applied not to the upper and lower louvers 10 of the air outlet 3 but to a plurality of left and right louvers 9 (outlet louvers) arranged in the left and right direction of the air outlet 3.

That is, the left and right louvers 9 of this embodiment have the same structure as that of the gel part 10b having the structure described in the first embodiment, provided not in the horizontal direction but in the vertical direction. In addition, 23 shows the support tool 15 which supports the same gel component 10b on the upper wall of the outlet 3a.

As in the case of the upper and lower louvers 10 of the first embodiment described above, the left and right louvers 9 of the PVA-PAA gel of each gel part 10b draw a smooth curve in the leftward or rightward direction by the applied DC electric field. Flexing to the right,
The shape is changed to a shape suitable for blowing to the left and right, and the same effect as that of the first embodiment is obtained. In addition,
The left and right louvers 9 may also have the insulating structure as described in the second embodiment and the connecting structure using a plurality of gel parts as described in the third embodiment. FIG. 7 shows a fifth embodiment of the present invention. In this embodiment, this invention is applied to the suction port 2
It is applied to the two suction louvers 8 (inlet louvers) in a.

Specifically, the suction louver 8 has a structure in which the gel part 10b having the structure described in the first embodiment is used as it is. When the indoor unit is not operating, the chain double-dashed line in FIG. The closed louver 8 and the upper surface of the main body 1 are in a closed state as shown by, and when the indoor unit is in operation, the intake louver 8 is bent and deformed as shown by the solid line in the figure to guide the intake air. The shape is changed to a suitable shape. The base portion of the suction louver 8 is supported by a support tool (not shown). Of course, the left and right louvers 9 may also have the insulating structure as described in the second embodiment and the connecting structure using a plurality of gel parts as described in the third embodiment. 8 and 9 show a sixth embodiment of the present invention. In this embodiment, the present invention is applied not to the indoor unit but to a flow rate control valve for controlling the flow rate of the blown air flowing in the duct of the blower system. To describe the present embodiment, reference numeral 30 in the drawing denotes a duct (corresponding to the flow passage of the present application), one end of which is connected to the inlet and the other end is connected to the outlet.

On each upper and lower wall of the duct portion between the inlet and the outlet, a vane 31 constituted by the polymer gel actuator 10a having the constitution described in the first embodiment,
31 is projected toward the center. In addition, 31a shows the support tool which the vane 31 supports. Each vane 31,3
A DC variable power supply 16, a controller 17, and an operation unit 18 are connected to the one parallel electrode 12, 12 as in the first embodiment.

As a result, when the operating portion 18 is operated, as in the first embodiment, the vanes 31, 31 are moved from the fully closed state shown in FIG. 9A to the fully opened state shown in FIG. 9C. The flow rate of the blown air flowing through the duct 30 can be varied by causing a bending deformation in the. Note that FIG.
(B) shows the state of the vanes 31, 31 which are bent and deformed in the middle between the fully closed state and the fully opened state.

That is, the polymer gel actuator 10
The a and 10a deform themselves only by an electric signal, and the deformed polymer gel actuators 10a and 10a can adjust the flow rate of the blown air.

Therefore, as described in the first embodiment above, a mechanical structure that causes problems such as complexity, large size, and heavy weight is not required, and the number of air parts is minimized. The flow can be controlled easily. Moreover, vane 3
Since No. 1 and No. 31 are smoothly bent, the flow is less disturbed and no sound is generated.

As a matter of course, the insulating structure as described in the second embodiment and the connecting structure by a plurality of gel parts as described in the third embodiment may be used for the vanes 31, 31. .

In the above embodiment, the present invention is
The present invention has been applied to the device for controlling the air flow in the indoor unit and the device for controlling the air flow in the air duct, but it is not limited to this, and it goes without saying that it may be applied to a device for controlling a fluid such as another liquid. Absent.
