Description

  The present invention relates to an air outlet adjustment register used for an air outlet of an air conditioner such as an automobile, and more particularly to a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction.

  As a register for air blowing adjustment used for air outlets for air conditioning of automobiles, etc., a laterally movable louver and a longitudinally movable louver are arranged in front and rear in a bezel or retainer that forms a ventilation path, and provided on the bezel A resistor that adjusts the air blowing direction by changing the angle of each fin of the laterally movable louver and the longitudinally movable louver when air is blown from the air outlet is generally used in air conditioning of automobiles.

  As this type of register, a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and provided with a few movable fins on the inside of the air outlet is mainly designed and It may be produced from design demand. Such a register is known, for example, from Patent Document 1 below.

JP 2002-103954 A JP 2009-160981 A

  Since the register having the elongated air outlet has an elongated shape that is long in the longitudinal direction and short in the lateral direction, the number of movable fins that are long in the longitudinal direction is inevitably about 1 to 3. Since the number of the air blower outlets is reduced and the short direction of the air outlet is narrowed, and the front movable fin is disposed at the narrowed air outlet, the pressure loss due to the front movable fin during blowing is likely to increase.

  Further, in such a register having a long and narrow air outlet in the longitudinal direction, when the number of fins along the longitudinal direction is as small as, for example, about one or two, the direction of the fin is changed to the short side of the air outlet. Even if the direction is changed up and down or left and right along the direction, it is difficult to sufficiently change the direction of the wind in that direction, and the directivity of the wind tends to deteriorate.

  Therefore, according to Patent Document 2, the present applicant arranges one front movable fin on the inner side of the air outlet in a register provided with an elongated air outlet that is long in the longitudinal direction and short in the lateral direction. We have proposed a register designed to reduce the pressure loss during blowing and to improve the directivity of the wind.

  However, in this register, one front movable fin is arranged along the longitudinal direction inside the air outlet, and the front movable fin is rotated around a support shaft parallel to the longitudinal direction, Although it is possible to improve the directivity of the wind when the direction of the fin is changed by adjusting the wind direction, the front movable fin is arranged in the ventilation path to reduce the pressure loss at the time of blowing. There was a limit and further improvement was desired.

  The present invention solves the above-described problems, and in a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, the movable fin is completely eliminated, the structure is simplified, and the air is blown. It is an object of the present invention to provide a register that can reduce the pressure loss and can adjust the wind direction well.

The air flow blocking members of the first flow channel, the central flow channel, and the second flow channel are selectively blocked to selectively perform the first flow channel, the central flow channel, or the second flow. Blowing through the road, changing the wind direction in the short direction of the air outlet ,
The first blower blocking member and the second blower blocking member are selectively blocked to change the air direction in the longitudinal direction of the air outlet .

  According to the present invention, the air flow from the air outlet is selectively performed by blowing air through the first flow channel, the central flow channel, or the second flow channel without providing the movable fin in the flow channel of the register body. Therefore, it is possible to adjust the wind direction with a simple structure and to blow air with little pressure loss.

Further, by selectively blocking the first blower blocking member and the second blower blocking member, the direction of the wind blown from the air outlet through the central channel is changed to the longitudinal direction of the air outlet. be able to.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 6, this register has a case-like register body 1, and is provided with a three-layered flow path inside as a ventilation path. An air outlet 2 is provided. As shown in FIG. 1, the air outlet 2 in front of the register is formed in a flat and elongated slit shape, and is a horizontally long rectangle that is long in the longitudinal direction (horizontal direction in the left and right) and short in the lateral direction (vertical direction). . Here, the L direction shown in FIG. 1 is the longitudinal direction, and the S direction is the short direction.

  In the register body 1, as shown in FIG. 3, the first flow path 3, the central flow path 4, and the second flow path 5 are parallel to the longitudinal direction of the air outlet 2 as a three-layer flow path. The first flow path 3 and the second flow path 5 are formed in three layers on the top and bottom along the plane, with the central flow path 4 interposed therebetween. A partition wall 3a is provided between the first channel 3 and the central channel 4, a partition wall 5a is provided between the second channel 5 and the central channel 4, and the central channel 4 is partitioned by the partition walls 3a and 5a. Both side portions are formed as plate-like spaces surrounded by the side walls of the register body 1. The first flow path 3 is formed as a plate-like space in the register body 1 above the central flow path 4 via the partition wall 3a, and the second flow path 5 is registered below the central flow path 4 via the partition wall 5a. A plate-like space is formed in the main body 1. Moreover, the front-end | tip part (downstream side front-end | tip) of the 1st flow path 3, the center flow path 4, and the 2nd flow path 5 is respectively long and long in the longitudinal direction similarly to the shape of the air blower outlet 2, and is short and short shape. Is formed.

  As shown in FIG. 2, the outer shape of the tip of the register body 1 is narrowed in the short direction, and a slit-like air outlet 2 that is elongated in the longitudinal direction is formed in front of the tip. The As shown in FIG. 3, the front end portion of the first flow path 3 formed in the register main body 1 communicates with the air blowout outlet 2 through the upper inclined flow path 7 that converges on the air blowout opening 2. The tip of 5 communicates with the air outlet 2 through the lower inclined flow path 8 that converges on the air outlet 2. The front end of the central channel 4 is formed so as to communicate with the immediately preceding air outlet 2 through the channel space 6 that follows the upper inclined channel 7 and the lower inclined channel 8.

  Furthermore, the tip of the lower partition 3a of the first channel 3 forming the central channel 4 and the tip of the upper partition 5a of the second channel 5 are tapered as shown in FIG. The surfaces 3b and 5b are formed so as to protrude into the channel space 6, and an upper inclined channel 7 and a lower inclined channel 8 are formed outside the inclined surfaces 3b and 5b.

  As a result, the air flow flowing through the central flow path 4 is blown forward from the air outlet 2 with less pressure loss, and the air flow flowing through the first flow path 3 is inclined with the upper inclined flow path 7. The airflow that passes through the surface 3b and changes the wind direction obliquely downward is blown, and the airflow that flows through the second flow path 5 passes through the lower inclined flow path 8 and the inclined surface 5b and is blown with the wind direction changed obliquely upward. It has become. When the first flow path 3 and the central flow path 4 are open, the air flow in the central flow path 4 is bent obliquely downward by the air flow in the first flow path 3 in the central flow path space 6, The air is well guided from the outlet 2 obliquely downward. When the second flow path 5 and the central flow path 4 are open, the air flow in the central flow path 4 is bent obliquely upward by the air flow in the second flow path 5 in the central flow path space 6, It is guided obliquely upward from the outlet 2 and blows air.

  As described above, in order to selectively blow air through the first flow path 3, the central flow path 4, or the second flow path 5, as shown in FIGS. The upper damper 11, the first center damper 12, the second center damper 13, and the lower damper 14 are disposed on the upstream side of the central flow path 4 and the second flow path 5, respectively, as blower blocking members. The upper damper 11 is rotatably supported in the first flow path 3 via a support shaft 11a, and is disposed so as to be able to block the air flow in the first flow path 3. The lower damper 14 is pivotally supported in the second flow path 5 via a support shaft 14a, and is disposed so as to be able to block the blowing of the second flow path 5.

  Therefore, by opening and closing the upper damper 11 and the lower damper 14, it is possible to blow using only the first flow path 3 or the second flow path 5, thereby changing the wind direction upward or downward. Can do. That is, when only the upper damper 11 is opened, an air flow flows only in the first flow path 3, and it is blown obliquely downward from the air outlet 2 through the upper inclined flow path 7 at the tip. In addition, when only the lower damper 14 is opened, an air flow flows only in the second flow path 5, which passes through the lower inclined flow path 8 at the tip and is blown obliquely upward from the air outlet 2. The blowing direction from the blower outlet 2 is changed to the short direction.

  As shown in FIGS. 5 and 6, two fixed fins 18 are fixed in a divergent shape for the air blowing guide in the first flow path 3, and two sheets of the fixed fins 18 are also fixed in the second flow path 5. The fixed fin 19 is fixed in the same form.

  On the other hand, as shown in FIG. 4, the central damper is divided into a first central damper 12 and a second central damper 13 that are divided into left and right, and the left first central damper 12 is a support shaft 12a in the central flow path 4. And the right second central damper 13 can be pivotally supported in the central flow path 4 via a support shaft 13a. In addition, the air flow on the right side of the central flow path 4 can be blocked.

  Further, as shown in FIG. 4, a plurality of fixing fins 9 are fixed in the central flow path 4 so as to form a flow path that widens toward the left and right fronts. 1 When the central damper 12 is opened and the second central damper 13 on the right side is closed, the air flow passing through the central flow path 4 is bent to the left side and is blown from the air outlet 2. On the other hand, when the second central damper 13 on the right side is opened and the first central damper 12 on the left side is closed, the air flow passing through the central flow path 4 is bent to the right side and is blown from the air outlet 2. That is, by switching the opening and closing of the first central damper 12 and the second central damper 13, the blowing direction in the longitudinal direction (left-right direction) of the central flow path 4 and the longitudinal direction of the first flow path 3 and the second flow path 5. The blowing direction of can be changed.

  Although not shown, the upper damper 11, the first center damper 12, the second center damper 13, and the lower damper 14 are provided with an opening / closing drive mechanism for driving the opening / closing thereof, either manually or by motor drive. The support shaft of each damper is rotationally driven to open and close the upper damper 11, the first center damper 12, the second center damper 13, and the lower damper 14.

  Next, the operation of the register having the above configuration will be described with reference to FIGS. The register is attached to an instrument panel or a dashboard portion in an automobile by connecting a back side air inlet to a ventilation duct (not shown). The resistor air outlet 2 is exposed on the front of the instrument panel and dashboard, but there are no visually conspicuous movable fins inside the air outlet 2, and the air outlet 2 is designed to be very long and simple. , The design of the front is innovative and excellent.

  When air is blown straight to the front of the register, the upper damper 11 of the first flow path 3 and the lower damper 14 of the second flow path 5 are shown in FIGS. Is closed, and the first central damper 12 and the second central damper 13 of the central flow path 4 are opened to blow air. As a result, as shown in FIGS. 7A and 7B, the air flow introduced into the central flow path 4 of the register body 1 is straightened through the central flow path 4. It progresses toward 2 and it blows straight in the front direction of a register | resistor from the air blower outlet 2 located in the front. Although the air blowout port 2 is formed in a slit shape in the lateral direction, since there is no movable fin in the central flow path 4 or the flow path space 6 at the tip thereof, there is little pressure loss at the time of air blowing, and air is blown efficiently and satisfactorily. can do.

  On the other hand, in this state, when the air is swung to the right, for example, the first central damper 12 on the left side is closed as shown in FIG. As a result, the air flow passes through the portion of the second central damper 13 on the right side of the open central flow path 4, and the fixed fins 9 of the right central flow path 4 are inclined to the right. The air is swung in the right direction and is blown toward the diagonal right side of the air outlet 2 in the longitudinal direction. On the other hand, when swinging leftward in the air blowing direction, the right second central damper 13 is closed and the left first central damper 12 is opened as shown in FIG. 7-2 (c). As a result, the air flow passes through the left first central damper 12 portion of the open central flow path 4, and the fixed fins 9 of the left central flow path 4 are inclined to the left. The air is swung leftward and is blown toward the left side of the longitudinal direction of the air outlet 2.

  On the other hand, when the wind is swung downward in the front lateral direction of the register, as shown in FIG. 9, the upper damper 11 of the first flow path 3 is opened, and the first central damper 12 and the second center of the central flow path 4 are opened. The damper 13 is opened and the lower damper 14 of the second flow path 5 is closed to blow air. As a result, as shown in FIG. 9, the air flow passes through the open first flow path 3 and the central flow path 4, and the air flow passing through the first flow path 3 flows from the upper inclined flow path 7 to the flow path space. When passing through 6, the air flow through the central flow path 4 is bent obliquely downward. As a result, the air flow passing through the central flow path 4 is bent obliquely downward, and the air flow passing through the first flow path 3 is blown obliquely downward from the air outlet 2.

  When one of the first central damper 12 or the second central damper 13 of the central flow path 4 is closed in this air blowing state, as shown in FIGS. 7A and 7B (b) and (c). Since the air flow passing through the central flow path 4 is swung to the right or left in the longitudinal direction, the wind directed obliquely downward is bent to the right or left in the longitudinal direction.

  On the other hand, when the wind is directed further downward than the above-described downward wind, as shown in FIG. 8, the upper damper 11 of the first flow path 3 is opened, and the first central damper 12 of the central flow path 4 is The second central damper 13 and the lower damper 14 of the second flow path 5 are closed and blown. As a result, as shown in FIG. 8, the air flow passes only through the open first flow path 3 and passes through the flow path space 6 from the upper inclined flow path 7, so that the wind direction is further strengthened obliquely downward. It is bent and blown from the air outlet 2 obliquely downward. Thus, even when the air blowing direction is directed downward, there is no movable fin in the first flow path 3, the upper inclined flow path 7 or the flow path space 6. be able to.

  On the other hand, when the wind is directed to the upper front side of the register, the lower damper 14 of the second flow path 5 is opened and the first central damper 12 and the second central damper 13 of the central flow path 4 are opened as shown in FIG. Open and close the upper damper 11 of the first flow path 3 to blow air. Thus, as shown in FIG. 11, the air flow passes through the open second flow path 5 and the central flow path 4, and the air flow passing through the second flow path 5 flows from the lower inclined flow path 8 to the flow path space. When passing through 6, the air flow through the central flow path 4 is bent obliquely upward. As a result, the air flow passing through the central flow path 4 is bent obliquely upward, and the air flow passing through the second flow path 5 is blown obliquely upward from the air outlet 2.

  In this state, when one of the first central damper 12 or the second central damper 13 of the central flow path 4 is closed, as shown in FIGS. 7-1 and 7-2 (b) and (c), The air flow passing through the central flow path 4 is bent to the right or left in the longitudinal direction, and the wind directed obliquely upward is directed to the right or left in the longitudinal direction.

  On the other hand, when the wind is further greatly shaken to the upper front side, as shown in FIG. 10, the lower damper 14 of the second flow path 5 is opened, and the first central damper 12, the second central damper 13 of the central flow path 4, and The upper damper 11 of the first flow path 3 is closed and blown. As a result, as shown in FIG. 10, the air flow passes through the open second flow path 5 and passes through the flow path space 6 from the lower inclined flow path 8, whereby the wind direction is further bent obliquely upward, Air is blown obliquely upward from the air outlet 2. Even when the air flow is bent upward and the air is blown, the second flow path 5, the lower inclined flow path 8 or the flow path space 6 has no movable fin. Can blow.

  As described above, the movable fin is not provided in the flow path of the register body 1, and air is selectively blown through the first flow path 3, the central flow path 4, or the second flow path 5, so Since the air blowing direction can be changed up and down (short direction) or left and right (longitudinal direction), it is possible to adjust the air direction with a simple structure and perform air blowing with little pressure loss. .

  In the above embodiment, the damper is used as the air blowing blocking member, and the damper is rotated to open and close the flow path, and the air blowing direction is changed, but the film or the sheet is used and the flow path is changed by sliding it. It can be opened and closed.

  Moreover, in the said embodiment, although the register | resistor which had the air blower outlet 2 of the shape elongated in the horizontal direction which was long in the horizontal horizontal direction and was short in the up-down vertical direction was made into the state rotated 90 degree | times, the vertical vertical direction The first flow path, the central flow path, and the second flow path are parallel to the longitudinal direction of the air blower outlet in the register main body having an air blower outlet that is long and short in the lateral direction and elongated in the vertical direction. It can also be formed in three layers along a vertical plane. In this case, by selectively blowing air to the first and second flow paths, the blowing direction of the air outlet changes to the left and right.
