The blade 18 has a first wing 19 and a second wing 20 spaced 90 degrees apart from each other with respect to the center of rotation. The first wing 19 and the second wing 20 are each in the shape of a semi-disc, and two semi-discs are combined in an L-shape. However, a certain region of the portion that meets at the center of rotation is recessed outward have. That is, a recessed portion 22 of a 1/4 sphere shape is formed between the first wing 19 and the second wing 20. The space is extended by the depressed portion 22 in a certain region of the rotation center where the first wing 19 and the second wing 20 contact with each other and the fluid can smoothly move through the expansion space 22a have. This will be described later with reference to FIG.

A motor shaft connecting portion 23 having a motor shaft connecting hole 23a is formed at an upper portion of a rotation center where the first wing 19 and the second wing 20 contact with each other and a lower shaft connecting hole 24a is formed at a lower portion And a lower shaft connection portion 24 is provided. That is, the motor of the driving unit 25 is interlocked with the motor shaft connecting hole 23a, and the lower shaft 13a of the lower case 13 is fitted into the lower shaft connecting hole 24a. Therefore, a virtual straight line connecting the motor shaft connecting portion 23 to the lower shaft connecting portion 24 becomes the rotation center (rotation axis) of the blade 18.

FIG. 6 is a view for explaining the channel connection state according to the rotational position of the blade 18. FIG. 6 (a), when the first wing 19 and the second wing 20 of the blade 18 are straddled at both ends of the flow path C 17, the flow path C 17 is shut off and the flow path A ( 15 and the flow path B 16 are connected. 6 (b), when the blade 18 rotates and the first wing 19 and the second wing 20 are attached to both ends of the flow path A 15, the flow path A 15 is blocked and the flow path B (16) and the flow path C (17) are connected. 6 (c), when the first wing 19 and the second wing 20 are placed on both ends of the flow path B 16, the flow path B 16 is blocked and the flow path A 15 and the flow path C 17 are connected. 6 (d), when the first wing 19 and the second wing 20 are located on the inner side of the duct connecting portion 11 and on the surface facing the flow path C 17, the flow paths of the flow paths A 15, Both the flow path B 16 and the flow path C 17 are connected. The blade 18 can be controlled so that the variable damper unit 10 according to the present embodiment is applied to any device so that the various flow path connection states shown in Fig.

A motor (not shown) for rotating the blade 18 may be a stepping motor capable of rotating at a predetermined angle according to a pulse signal. The blade 18 rotates in units of 90 degrees, (A) to (d) of FIG. Of course, various types and control methods can be applied to motors in addition to stepping motors.

Although the first wing 19 and the second wing 20 constituting the blade 18 are shown in an L-shape in which they are spaced 90 degrees apart from each other, the flow path A 15, the flow path B 16, It is possible to shut off the specific flow path and connect the remaining flow paths even if the angle of the first blade 19 and the second blade 20 is 90 degrees or less.

The optional damper unit 10 according to the embodiment of the present invention described above with reference to FIGS. 1 to 6 is advantageous in that various flow paths can be selected only by rotation of the single blade 18. In addition, in order to smoothly move the fluid, 18 are formed with depressed portions 22.

That is, referring to FIG. 7, if the first wing 19 and the second wing 20 are coupled with each other as shown in FIG. 7 (b) It gets stuck. Therefore, the fluid that has entered the clogged part must first collide with the first wing 19 or the second wing 20, and the flow is interrupted. 7 (a), if the depressions 22 are formed at the portions where the first wings 19 and the second wings 20 are in contact with each other, the first wings 19 and the second wings 20 A part of the center of rotation of the contacting portion extends. Therefore, a substantial part of the fluid can move smoothly through the expansion space 22a without colliding with the vanes 19 and 20 in the movement path of the fluid.

As described above in detail, the selective damper unit 10 according to the embodiment of the present invention is able to select the flow path while rotating the L-shaped blade 18 at intervals of 90 degrees, . This optional damper unit 10 can be applied to various devices for interrupting the flow of fluid, and can exert a particularly powerful effect when applied to an air conditioning system.

Hereinafter, an example in which the selectable damper unit 10 according to the embodiment of the present invention described with reference to Figs. 1 to 7 is applied to the bypass air conditioning system will be described.

8 is a view for explaining a bypass air conditioning system using a selectable damper unit according to the first embodiment of the present invention. 8, the bypass air-conditioning system using the selectable damper unit according to the embodiment of the present invention includes a ventilator 100, optional damper units 10 and 10 ', a plurality of pipes 210, 220, 230 and 240, 250 and a controller 260.

First, the ventilator 100 includes a main body 110, a heat exchange element 119, a first fan 117, and a second fan 118.

The main body 110 having a predetermined space therein has a substantially rectangular parallelepiped shape (of course, a shape is not limited), and the first connecting portion 111 and the second connecting portion 112 are arranged upward in the outdoor direction, And a third connection part 113 and a fourth connection part 114 are provided downward in the indoor direction. The fifth connection part 115 and the sixth connection part 116 are provided on the left side of the drawing. The first connecting part 111 to the sixth connecting part 116 serve as passages for allowing air to flow into and out of the main body 110.

A heat exchanging element 119 is installed inside the main body 110. The inside of the main body 110 is divided into a first ventilation space 120 and a second ventilation space 120, (121). That is, the first ventilation space 120 extends from the first connection part 111 to the third connection part 113, and the second ventilation space 121 extends from the second connection part 112 to the fourth connection part 114.

The heat exchange element 119 installed in the main body 110 is a structure for preventing heat loss by crossing the indoor air and the outdoor air. The heat exchanging element 119 has a wide variety of types, one of which is shown in Fig. Referring to FIG. 9, the heat exchanging element 119 may be designed so that different passages are formed by stacking a flat plate and a bent plate, and the passages are orthogonal to each other.

When the outdoor air and the indoor air flow into the respective passages of the heat exchanging element 119, the outdoor air and the room air do not directly collide with each other or are mixed with each other by the flat plate material and the bent plate material. The heat exchanging element 119 shown in FIG. 9 is only one example, and its shape, material and structure are very diverse, and the heat exchanging element applicable to the present invention is not limited to a specific kind.

Referring again to FIG. 8, a first fan 117 is installed in the first connection part 111 and a second fan 118 is installed in the fourth connection part 114 in the main body 110. The first fan 117 and the second fan 118 are rotated by a rotational power generated by a fan driving motor (not shown) to generate a flow of air. Specifically, the first fan 117 generates the air flow in the outdoor direction at the first connection portion 111, and the second fan 118 generates the air flow in the indoor direction at the fourth connection portion 114.

A first selectable damper unit 10 is installed outside the second connection portion 112 of the main body 110 and a second selectable damper unit 10 'is provided on the third connection portion 113. Detailed configuration of the first selectable damper unit 10 and the second selectable damper unit 10 'can be seen from FIGS. 1 to 7, and in FIGS. 8 and 10, the first selectable damper unit 10' (10) and the second selectable damper unit (10 ').

The flow path A 15 of the first selectable damper unit 10 is connected to the outdoor side and the flow path B 16 is connected to the second connection portion 112 and the flow path C 17 is connected to the second bypass piping 220 ). The flow path A 15 'of the second selectable damper unit 10' is connected to the third connection portion 113, the flow path B 16 'is connected to the indoor side, and the flow path C 17' And is connected to one side of the bypass pipe 210.

In addition, the other side of the second bypass pipe 220 is connected to the fifth connection part 115, and the other side of the first bypass pipe 210 is connected to the sixth connection part 116. Here, the fifth connection part 115 is provided at a position adjacent to the second fan 118. That is, the fifth connection part 115 shares the second ventilation space 121 together with the second fan 118 and the fourth connection part 114. The sixth connection portion 116 is provided at a position adjacent to the first fan 117. Accordingly, the sixth connection part 116 shares the first ventilation space 120 together with the first fan 117 and the first connection part 111. [

The first connection unit 111 is connected to the outdoor unit through the outdoor connection pipe 230 and the fourth connection unit 114 is connected to the indoor unit through the indoor connection pipe 240.

The first fan 117 and the second fan 118 are operated by receiving a control signal from the controller 250 according to a user command input through the controller 260. The first and second fans 117, The rotational position of the blades 18 and 18 'of the optional damper unit 10' is also determined by a control signal transmitted from the controller 250 according to a user command input through the controller 260.

That is, the user can select the general ventilation mode, that is, the heat exchange ventilation mode or the bypass ventilation mode through the controller 260.

If there is a large difference between indoor and outdoor temperature, such as summer or winter, heat loss is unconditional if ventilation is performed. Therefore, when the heat exchange ventilation mode is set through the controller 260, the operation is performed as shown in FIG.

That is, the blade 18 of the first selectable damper unit 10 and the blade 18 'of the second selectable damper unit 10' are in a state as shown in FIG. 6 (a) And the flow path A (15, 15 ') and the flow path B (16, 16') are connected.

When the first fan 117 and the second fan 118 operate in this state, the room air passes through the flow path B 16 'and the flow path A' 15 'of the second selectable damper unit 10' And enters the first ventilation space 120 inside the main body 110 through the third connection part 113. [ Then passes through the heat exchange element 119 and is discharged to the outside through the first connection part 111 and the outdoor connection pipe 230.

In addition, the outdoor air passes through the flow path A 15 and the flow path B 16 of the first selectable damper unit 10 and flows into the second ventilation space 121 inside the main body 110 through the second connection portion 112 Enter. Similarly, the outdoor air passes through the heat exchange element 119 and then flows into the room along the fourth connection part 114 and the indoor connection pipe 240.

When the heat exchange ventilation mode is set through the controller 260, the blades 18 and 18 'of the first selectable damper unit 10 and the second selectable damper unit 10' are positioned as shown in FIG. 8, A heat exchange ventilation mode is established in which the heat exchange element 119 crosses to perform heat exchange.

On the other hand, the outdoor air can be directly introduced into the room in the season when the indoor / outdoor temperature difference is not large. The operating state of the bypass air conditioning system in this case is shown in Fig.

The blade 18 of the first selectable damper unit 10 cuts off the flow path B 16 and connects the flow path A 15 and the flow path C 17 as shown in FIG. 6C.

6 (b), the blade 18 'of the second selectable damper unit 10' blocks the flow path A 15 'and connects the flow path B 16' and the flow path C 17 ' State.

When the first fan 117 and the second fan 118 operate in this state, the room air passes through the flow path B (16 ') and the flow path C (17') of the second selectable damper unit 10 ' And enters the first ventilation space 120 inside the main body 110 through the first bypass pipe 210 and the sixth connection part 116. That is, the indoor air enters through the third connecting part 113 and is not moved to the first connecting part 111 via the heat exchanging element 119, but is transferred to the first fan 117 through the first bypass pipe 210, And is immediately discharged to the outside through the first connection part 111 and the outdoor connection pipe 230 by the suction force of the first fan 117. [

In addition, the outdoor air passes through the flow path A (15) and the flow path C (17) of the first selectable damper unit 10 and flows through the second bypass pipe 220 and the fifth connection part 115 The second ventilation space 121 is opened. Likewise, the outdoor air does not pass through the second connection part 112 and pass through the heat exchanging element 119 but directly through the second bypass pipe 220 to the fifth connection part 115 adjacent to the second fan 118 And flows into the room along the fourth connection part 114 and the indoor connection pipe 240 by the suction force of the second fan 118.

That is, when the bypass ventilation mode is set through the controller 260, the blades 18 and 18 'of the first selectable damper unit 10 and the second selectable damper unit 10' are positioned as shown in FIG. 10, Without direct heat exchange.

8 through 10, the bypass air conditioning system using the selectable damper unit according to the first embodiment of the present invention does not need to greatly change the design of the interior by extending the existing ventilator. In other words, only the installation of the optional damper unit 10, 10 'and the bypass piping 210, 220 is required while maintaining the state of the existing ventilation device as much as possible, and the blade 18 of the optional damper unit 10, 10' , 18 ') only by changing the rotational position, it is possible to operate both the heat exchange ventilation mode and the bypass ventilation mode.

In addition, since the air for bypassing is not supplied through a fan which stops moving, but is supplied and exhausted through a separate bypass pipe, there is no air loss, and the motor for driving the fan always operates only in the originally designed rotational direction, There is no possibility of damage to motor and control PCB due to reverse current.

On the other hand, the heat exchange ventilation mode and the bypass ventilation mode may be set according to the user command input through the controller. However, after the indoor and outdoor temperature differences are different from each other, And operate in bypass ventilation mode if the temperature difference is within a certain range.

Further, the optional damper unit 10 described above has the T-shaped flow path formed in the duct connecting portion 11, and the L-shaped blade 18 having the 90-degree interval corresponding thereto rotates at 90- The angle of the first wing 19 and the second wing 20 of the blade 18 may be 90 degrees or less even if the flow path size is small as described above. And further, the flow path formed in the duct connecting portion 11 may be formed in a shape other than a T-shape.

For example, three flow paths are formed in a Y-shape having 120-degree intervals. In this case, if the angles of the first wing 19 and the second wing 20 of the blade 18 are designed to block a specific one of the Y-shaped flow paths, the remaining two flow paths are selectively connected It is possible. Of course, the blade 180 in this case may be rotated at an interval of 120 degrees to change the flow path connection.

That is, the optional damper unit to be dealt with in the present invention simplifies the control by allowing the specific flow path to be closed and the remaining flow paths to be connected only by rotating the single blade, And should not focus on the shape or the angle of the first wing 19 and the second wing 20. Of course, when the flow type of the selective damper unit 10 is different, a method of connecting the pipes to the respective flow paths may be different.

11 is a view for explaining a bypass air conditioning system using a selectable damper unit according to a second embodiment of the present invention. The bypass air conditioning system shown in Fig. 11 is similar to the bypass air conditioning system according to the first embodiment described with reference to Figs. 8 to 10, but differs in the structure in which the selective damper unit and the pipes are connected to the ventilation apparatus.

The air conditioning system shown in FIG. 11 will be described in more detail as follows. The bypass air conditioning system according to the second embodiment includes a ventilator 300, a first selectable damper unit 10, a plurality of pipes 410, 420, 430 and 440, a controller 450 and a controller 460.

The ventilator 300 includes a main body 310, a heat exchange element 319, a first fan 317, and a second fan 318.

The main body 310 is provided with a first connecting portion 311 and a second connecting portion 312 upward in an outdoor direction with reference to FIG. 11, and a third connecting portion 313 and a fourth connecting portion 314, Respectively. In addition, a fifth connection portion 315 is provided on the left side of the drawing. Unlike the main body 110 of the first embodiment, the main body 310 of the present embodiment is not provided with the sixth connection portion. Of course, even if the sixth connecting portion is provided, it is not used in the second embodiment.

The flow path A 15 of the first selectable damper unit 10 is connected to the outdoor side and the flow path B 16 is connected to the first connection portion 311 and the flow path C 17 is connected to the bypass piping 410 It is connected with one side. Here, the other side of the bypass pipe 410 is connected to the fifth connection part 315.

The second connection unit 312 of the main body 310 is connected to the outside through the outdoor connection pipe 420 and the third connection unit 313 and the fourth connection unit 314 are connected to the first indoor connection pipe 430 2 < / RTI > indoor connection pipe (440).

The first fan 317 and the second fan 318 that generate a flow of air are installed in the first connection part 311 and the fourth connection part 314, respectively. The air flow generated in accordance with the operation of the first fan 317 and the second fan 318 can be inferred through the first embodiment and the description of the heat exchange element 319 is also superseded.

In the first embodiment, the first fan 117 and the second fan 118 operate together in the heat exchange ventilation mode and the bypass ventilation mode, but the second embodiment operates differently according to the mode.

That is, the user selects the heat exchange ventilation mode through the controller 460 or sets the bypass ventilation mode so that the control unit 450 outputs the signal according to the mode to the first fan 317, the second fan 318, To the damper unit 10 so as to generate an air flow. An operation state according to each mode will be described below.

When the user sets the heat exchange ventilation mode, the blade 18 of the first selectable damper unit 10 shuts off the flow path C (17) (as shown in Fig. 6 (a) A 15 and the flow path B 16 are connected to each other. Also, in the heat exchange ventilation mode, a signal is output from the controller 450 so that the first fan 317 and the second fan 318 are both operated.

Accordingly, the room air is discharged to the outside through the first indoor connection pipe 430, the third connection part 313, the heat exchange element 319, the first connection part 311, and the first selectable damper unit 10, Is introduced into the room through the outdoor connection pipe 420, the second connection portion 312, the heat exchange element 319, the fourth connection portion 314, and the second indoor connection pipe 440. That is, indoor and outdoor air crosses at the heat exchange element 319 to perform heat exchange.

On the other hand, when the bypass ventilation mode is set in the controller 460, the blade 18 of the first selectable damper unit 10 cuts off the flow path B 16 (as shown in FIG. 6C ) State and connects the flow path A 15 and the flow path C 17 to each other.

At this time, the first fan 317 is not operated and only the second fan 318 is operated. The outdoor air introduced through the flow path A 15 of the first selectable damper unit 10 flows into the bypass pipe 410 through the flow path C 17 and flows through the fifth connecting portion 315 to the second ventilation (A space extending to the second connecting portion 312 and the fourth connecting portion 314), and then is directly supplied to the room through the fourth connecting portion 314 and the second indoor connecting pipe 440. That is, bypass operation is performed for the bypass ventilation mode, more specifically, the operation for supplying air to the room outdoors.

In this case, there is a possibility that outdoor air may flow through the second connection part 312 due to the operation of the second fan 318. When a second damper is installed in the second connection part 312 to operate the air supply bypass ventilation mode, If the connecting portion 312 is to be cut off, no air inflow through the second connecting portion 312 occurs.

Of course, even if the second connection portion 312 is opened, the first connection portion 311 is blocked by the blade 18 of the first selectable damper unit 10, and furthermore, the first fan 317 is stopped The flow of air does not occur in the first ventilation space connecting the first connection portion 311 and the third connection portion 313. That is, according to the operation of the second fan 318, even if outdoor air passes through the second connection part 312 and then passes through the heat exchange element 319, since there is no air flow through the first ventilation space, 319) does not occur, meaning that the air supply bypass function of outdoor air is maintained anyway.

In addition, a sixth connection portion 516 is provided on the left side of the drawing. Unlike the main body 110 in the first embodiment, the main body 510 of the present embodiment is not provided with the fifth connecting portion. Of course, even if the fifth connection portion is provided, it is not used in the third embodiment.

The flow path A 15 'of the second selectable damper unit 10' is connected to the fourth connection portion 514, the flow path B 16 'is connected to the indoor side and the flow path C 17' (Not shown). The other side of the bypass pipe 610 is connected to the sixth connection part 516.

The first connection part 511 and the second connection part 512 of the main body 510 are connected to the outside through the first outdoor connection pipe 620 and the second outdoor connection pipe 630, Is connected to the room through the indoor connection pipe (640). The first fan 517 and the second fan 518 are installed in the first connection part 511 and the fourth connection part 514, respectively.

The operation of the bypass air-conditioning system according to the third embodiment will now be described.

When the user sets the heat exchange ventilation mode, the blade 18 'of the second selectable damper unit 10' blocks the flow path C 17 '(as shown in FIG. 6 (a) And the flow path A 'and the flow path B' are connected to each other.

At this time, the second fan 518 is not operated and only the first fan 517 is operated. Accordingly, the room air introduced through the flow path B 'of the second selectable damper unit 10' flows into the bypass pipe 610 through the flow path C '17' and flows through the sixth connection part 516 Enters a first ventilation space (a space extending to the first connection portion 511 and the third connection portion 513), and then is directly discharged outdoors through the first connection portion 511 and the first outdoor connection pipe 620. That is, the bypass operation is performed in the bypass ventilation mode, more specifically, the operation of venting the room outdoors.

In this case, there is a possibility that room air may flow into the room through the third connecting part 513 by operating the first fan 517. Even if the third connecting part 513 is opened, the fourth connecting part 514 is connected to the second selectable damper unit Since the second fan 518 is stopped by the blade 18 'of the first fan unit 10' and further the second fan unit 518 is stopped, the second fan unit 518 is stopped by the second ventilation space connecting the second connection unit 512 and the fourth connection unit 514 No air flow occurs. That is, even if the indoor air flows through the third connection part 513 and then passes through the heat exchange element 519 according to the operation of the first fan 517, since there is no air flow through the second ventilation space, And the exhaust bypass function of the indoor air is maintained.
