  As a register for adjusting the air blowing of the air conditioner, the laterally movable louver and the longitudinally movable louver are arranged in the bezel or retainer forming the ventilation path so as to be perpendicular to each other, and air is supplied from the air outlet provided in the bezel. A resistor that adjusts the air blowing direction by changing the angle of each fin of the horizontally movable louver and the vertically movable louver is used for air conditioning of automobiles.

  2. Description of the Related Art In recent years, a register used for air conditioning for automobiles has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a small number of front movable fins of about 1 to 3 are provided inside the air outlet. In some cases, a thin register is manufactured mainly from design and design demands. Such a register is known, for example, from Patent Document 1 below.

JP 2002-103954 A

  In this type of thin register, about 1 to 3 front movable fins are arranged along the longitudinal direction inside a slender air outlet, and a number of rear movable fins are arranged upstream of the front movable fins. These are pivotally supported in the short direction perpendicular to the front movable fin, and are arranged in parallel in the longitudinal direction at intervals. However, because the air outlet of the register is elongated in the longitudinal direction and short in the lateral direction, the air flow blown from the ventilation path toward the air outlet is compressed in the lateral direction to generate a contracted flow In particular, the phenomenon that the directivity of the wind when the rear movable fin is shaken in the longitudinal direction is easily deteriorated due to the contracted flow.

  That is, a conventional register having such an elongated air outlet is usually long in the longitudinal direction and short in the front direction of the air passage 71 formed in the case body 70 of the register, as shown in FIG. A short elongated air outlet 72 is provided, and a small number of front movable fins 73 are arranged along the longitudinal direction inside the air outlet 72, and on the upstream side of the front movable fins 73, A large number of rear movable fins 74 are arranged in a direction orthogonal to the front movable fins 73.

  However, such a so-called slit type register has an air blowing outlet 72 that is elongated in the longitudinal direction and short in the lateral direction as shown in FIG. The compressed air flow is compressed in the short direction, and contraction flow is likely to occur. Particularly, when the rear movable fin 74 is swung left and right, that is, in the longitudinal direction, in the vicinity between the rear movable fin 74 and the front movable fin 73, An air flow compressed, that is, a flow of air compressed in the vertical direction is likely to occur.

  For this reason, when the front movable fin 73 is swung up and down and the rear movable fin 74 is swung left and right, that is, in the longitudinal direction, the direction of the air flow is returned by the contracted flow, so that the wind is difficult to bend and the rear movable fin 74 There existed a subject that the directivity of the wind when changing the direction of the fin 74 was easy to deteriorate.

  In addition, a damper plate is usually provided in the register in order to block the ventilation path, but the space in the register necessary for the damper plate, or the increase in the number of parts and the number of parts associated with the part. Is a problem.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a register that can improve wind directivity and can block an air passage with a simple structure.

In the register according to the present invention, an elongated air outlet that is long in the longitudinal direction and short in the lateral direction is provided at a front portion of the ventilation path in the case body, and the ventilation along the longitudinal direction in the vicinity of the air outlet is provided. A chevron ridge having an inclined surface on the upstream side is formed on both inner side surfaces in the road along the longitudinal direction, and the direction of the inclined surface of the chevron ridge is directed to the upstream side of the ventilation path. The chevron ridges are formed so as to bend and blow out the air flow in the ventilation path toward the center of the air outlet, and a plurality of front fins are disposed in the short direction on the upstream side of the chevron ridges. A front movable louver provided along the longitudinal direction is disposed, and the front fin is pivotally supported via a support shaft along the short side direction , and is arranged in parallel at intervals in the longitudinal direction. A back movable having one back fin that changes the wind direction in the short direction in the ventilation path upstream of the front movable louver. Over bar is, is rotatably supported via a support shaft along the longitudinal direction, to vent air passage wall surface of the upstream side near the該奥movable louvers and rear chevron convex stripes along the longitudinal direction The rear movable louver is protruded, and the air flow contracted by the rotation of the rear fin is bent in the direction opposite to the short direction bending by the rear fin by the mountain-shaped ridge to shorten the wind direction. The rear movable louver is configured to change in the hand direction, and when the inner fin is rotated to the vicinity of the maximum inclination angle, the end of the inner fin is in contact with the inner wall of the ventilation path to block the ventilation. It was configured as described above.

  According to the present invention, the wind direction can be changed to the short direction by turning only one back fin. For example, when the back fin is directed in the short direction, for example, obliquely upward, it flows through the ventilation path. The air flow is first bent and contracted obliquely upward in the short direction by the back fin, passes through the front movable louver in a contracted state, and changes the wind direction in the longitudinal direction according to the direction of the front movable louver, In that state, the air flow is then deflected and bent obliquely downward in the short direction through the chevron ridges and blown from the air outlet.

  For this reason, the current transformation part which changes a wind direction to a short direction (for example, up and down), the location of a back fin turns into a contraction part, and the part of a mountain-shaped protruding item | line becomes a deflection part, and a wind direction is made into a short direction (for example, diagonally downward) Or, the current changing operation when bending upward) is divided into the contracted flow by the back fin and the deflection by the chevron.

For this reason, when the air flow passes from the movable louver through the chevron ridge, the contracted flow (compressed air flow) decreases, thereby turning the front movable louver and changing the wind direction in the longitudinal direction. The phenomenon that the wind direction is returned by the contracted flow is reduced. For this reason, even in the case of a slit type register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, the direction of the front movable louver is set in the longitudinal direction while the back fin is shaken in the lateral direction. When shaken, the wind is not returned by the contracted flow, and the direction of the wind can be favorably changed according to the direction of the front movable louver to improve the directionality of the wind.
In addition, since the Okuyama shaped ridge protrudes along the longitudinal direction on the inner wall of the ventilation path near the upstream side of the inner movable louver, when the inner fin of the inner movable louver tilts, It is possible to effectively deflect the air flow along the direction in the tilt direction of the back fin and improve the directivity of the wind.

  In addition, the back movable louver blocks the ventilation path when the back fin is rotated to the vicinity of the maximum inclination angle, so there is no need to provide a damper plate in the register for closing the ventilation path, and there is no space for it. This can reduce the size of the case body and reduce the number of parts.

  Here, the above-mentioned chevron ridges are continuously formed on the opposite sides of the inner surface in the vicinity of the air outlet with the same cross section in the longitudinal direction of the air outlet, and further, on the downstream side of the chevron It is preferable to form the surface in a shape that is open so as to expand toward the front. According to this, it is possible to improve the directivity of the wind when the direction of the movable fin of the movable louver is changed while the back fin is shaken in the short direction.

  According to the register of the present invention, when the direction of the front movable louver is swung in the longitudinal direction while the direction of the rear movable louver is swung in the short direction, the wind is not returned by the contracted flow, and the front movable louver The wind direction can be changed favorably according to the direction of the wind, and the directivity of the wind can be improved. Further, the air blowing can be blocked by the turning operation of the back movable louver.

It is a front view of the register | resistor which shows one Embodiment of this invention. It is II-II sectional drawing of the register. It is a III-III sectional view of the register. It is a longitudinal cross-sectional view when a wind direction is turned to the short side direction upper side. It is a longitudinal cross-sectional view when the wind direction is directed downward in the short direction. It is a longitudinal cross-sectional view of a state in which the rear movable louver is rotated to block the ventilation path. It is sectional explanatory drawing of the conventional register | resistor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of the register, and FIGS. 2 and 3 show sectional views thereof. The case body 1 of the register is formed in a substantially rectangular parallelepiped thin box shape, and the ventilation passage 3 having a low height is formed inside, so that a so-called slit type register is formed. An air inlet is formed at the end opening of the air passage 3 in the case body 1, and in order to blow out the air passing through the air passage 3 on the front surface of the air passage 3, as shown in FIG. An air outlet 2 is formed.

  As shown in FIGS. 1 and 2, the air outlet 2 is formed in a flat and elongated slit shape, and is formed in a horizontally long rectangle that is long in the longitudinal direction (left and right direction) and short in the lateral direction (vertical direction). On the upper wall surface and the lower wall surface immediately inside the air outlet 2, ridges 6 and 7 are provided along the longitudinal direction of the air outlet 2.

  The upper and lower chevron ridges 6 and 7 are formed along the longitudinal direction on both upper and lower surfaces immediately inside the air outlet 2, and the height of each chevron ridge 6 and 7 is the embodiment of this drawing. The height of the air outlet 2 (the length of the short side in the vertical direction) is about 9%, and depending on the height of the air outlet 2, the height may be about 7 to 12%. it can.

  Further, the upper and lower chevron ridges 6 and 7 are formed with inclined surfaces 6a and 7a on the upstream side thereof. The inclined surfaces 6a and 7a on the upstream side of the chevron ridges 6 and 7 are each formed such that the inclined direction faces the front fin 51 of the front movable louver 5, and the inclined surfaces 6a and 7a of this embodiment are formed. The inclination angle with respect to the horizontal line is set to about 45 ° here, but can be set to about 35 ° to 55 ° depending on the height (length in the short direction) of the air outlet 2.

  As shown in FIG. 3, the chevron ridges 6 and the chevron ridges 7 are formed symmetrically with respect to the horizontal center line of the air outlet 2 at the opposite upper and lower portions of the inner wall surface of the air outlet 2. The Further, the chevron ridges 6 and the chevron ridges 7 are formed continuously in the longitudinal direction with the same cross section having a substantially triangular shape.

  On the other hand, the downstream surface of the chevron ridges 6, 7, that is, the surface on the front side of the register, opens so as to spread forward, that is, to widen forward and obliquely downward, upper and lower It is formed as a front inclined surface. As shown in FIGS. 4 and 5, the chevron ridge 6 and the chevron ridge 7 are blown out from the air outlet 2 when the downstream end of the back fin 81 of the back movable louver 8 is directed upward or downward. The air flow direction is bent downward or upward.

  That is, when the downstream end of the back fin 81 of the back movable louver 8 is directed upward (obliquely upward), the airflow flowing through the ventilation path 3 flows along the vicinity of the upper wall surface as shown in FIG. The angled surface 6a of the angle ridge 6 is bent downward and blown obliquely downward.

  On the other hand, when the downstream end of the back fin 81 is directed downward (obliquely downward), the airflow flowing through the ventilation path 3 flows along the vicinity of the lower wall surface as shown in FIG. It strikes the inclined surface 12a of the strip 7 and is bent upward and blown obliquely upward.

  Further, when blowing air obliquely downward or obliquely upward, the wind is well guided by the front inclined surface that is opened so as to spread forward, and the wind is directed without being disturbed by the edge of the opening. It is like that.

  Furthermore, as shown in FIG. 3, an Okuyama-shaped ridge 11 protrudes along the longitudinal direction on the upper wall surface 1a of the ventilation path 3 in the case body 1, and an Okuyama-shaped ridge is formed on the lower wall surface 1b. 12 protrudes along the longitudinal direction. The upper and lower back mountain-shaped ridges 11, 12 have substantially the same triangular cross section and are arranged to face each other at the upper part and the lower part in the ventilation path 3.

  Further, the back movable louver 8 has a function of blocking the ventilation path. When the back fin 81 is rotated to the maximum inclination angle (here, about 60 ° with respect to the horizontal axis), the top and bottom ends of the back fin 81 The part can contact the upper wall surface 1a and the lower wall surface 1b of the air passage 3. Thereby, the back movable louver 8 can close the ventilation path 3 and block the ventilation, and the back fin 81 is formed in a shape and size that can close the ventilation path 3. Although not shown, a sponge sheet or the like may be attached to the upper and lower ends of the back fin 81 so that the air passage 3 can be sealed and closed without a gap.

  The back fin 81 of the back movable louver 8 is linked to a dial knob (not shown), and changes the direction of the back fin 81 in the short direction according to the turning operation. The rear movable louver 8 can also be linked to a motor-driven variable wind direction device. By the operation of the variable wind direction device, the back fin 81 is shaken in the short direction, and the wind direction is set in the short direction of the air outlet 2. It can also be changed (up and down in this register).

  Furthermore, between the angle-shaped ridges 6 and 7 and the inner movable louver 8 in the ventilation path 3 of the case body 1, that is, on the upstream side of the angle-shaped ridges 6 and 7 and immediately downstream of the inner movable louver 8. The front movable louver 5 having the front fin 51 is disposed in a direction orthogonal to the back movable louver 8.

  As shown in FIGS. 1 and 2, the front movable louver 5 has a plurality of front fins 51 that can be rotated via a support shaft 52 extending in the short direction and arranged in parallel at intervals in the longitudinal direction. The air flow that is configured and contracted through the rear movable louver 8 is configured to change the wind direction in the longitudinal direction of the air outlet 2 according to the direction of the front fin 51.

  The front fins 51 of the front movable louver 5 are arranged vertically in the vertical direction (short direction) of the air outlet 2, and the support shafts 52 are short on the upper end and lower end of each front fin 51. Projected in the direction. The front fins 51 have their support shafts 52 fitted in shaft holes formed at intervals between the upper wall and the lower wall of the case body 1 and are pivotally supported so as to be laterally lateral in a front view. The direction of each front fin 51 is changed.

  As shown in FIG. 3, the crank portion 53 is connected to the support shaft 52 of each front fin 51 of the front movable louver 5, and one link member 55 is connected to the shift shaft 54 of all the crank portions 53. When one front fin 51 of the front movable louver 5 is rotated, all the front fins 51 are rotated in the same direction to change direction. The front fin 51 of the front movable louver 5 is linked to a dial knob (not shown), and is rotated so as to change the direction according to the rotation operation, so that the wind direction is changed to the longitudinal direction of the air outlet 2. Yes. The front movable louver 5 can also be linked to a motor-driven variable wind direction device. In this case, the wind direction is changed in the longitudinal direction of the air outlet 2 by the operation of the variable wind direction device (right or left direction in this register). To change structure.

  When changing the blowing direction upward, the register having the above configuration rotates the downstream end portion of the back fin 81 of the back movable louver 8 so as to face obliquely downward as shown in FIG.

  As a result, the air flow flowing through the ventilation path 3 is bent and contracted obliquely downward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the front fins 51 and changes the wind direction in the longitudinal direction (left and right direction) according to the direction of the front movable louver 5, and in this state, the air flow flowing through the ventilation path 3 is near the lower wall surface. It flows along, bends upward by hitting the inclined surface 7a of the lower chevron ridge 7, and is blown obliquely upward from the air outlet 2.

  On the other hand, when changing the blowing direction downward, as shown in FIG. 5, the inner fin 81 of the inner movable louver 8 is rotated so that its downstream end is directed upward.

  As a result, the air flow flowing through the ventilation path 3 is bent and contracted obliquely upward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the front fins 51 and changes the wind direction in the longitudinal direction (left and right direction) in accordance with the direction of the front movable louver 5, and in this state, the air flow flowing through the ventilation path 3 is near the upper wall surface. It flows along and is bent downward by hitting the inclined surface 6a of the upper chevron 6 and is blown obliquely downward from the air outlet 2.

  In this way, in the current-transforming portion that changes the wind direction in the short direction (vertical direction), the back movable louver 8 portion becomes a contraction portion, and the chevron ridges 6 and 7 portions become deflection portions, thereby shortening the wind direction. The current-transforming operation when bending obliquely downward or upward in the hand direction is divided into contraction by the rear movable louver 8 and deflection by the chevron ridges 6 and 7. For this reason, when the air flow passes from the front movable louver 5 through the chevron ridges 6 and 7, the contracted flow (compressed air flow) is reduced, whereby the front movable louver 5 is rotated to move the wind direction. The phenomenon that the wind direction is returned by the contracted flow is reduced when the is changed to the left and right longitudinal direction.

  For this reason, even in a register having an elongated air outlet 2 that is long in the longitudinal direction and short in the lateral direction, the direction of the front movable louver 5 is changed with the direction of the rear movable louver 8 being shaken in the lateral direction. When shaken in the longitudinal direction, the wind is not returned by the contracted flow, and the direction of the wind can be favorably changed according to the direction of the front movable louver 5 to improve the directionality of the wind.

  On the other hand, when blocking the ventilation of the ventilation path 3, the back knob 81 of the back movable louver 8 is rotated to the maximum inclination angle by operating a dial knob (not shown) or the like. At this time, as shown in FIG. 6, the upper and lower end portions of the back fin 81 abut against the upper wall surface 1 a and the lower wall surface 1 b in the ventilation path 3, the ventilation path 3 is closed, and ventilation is blocked.

  Thus, since the back fin 81 of the back movable louver 8 is rotated to block the ventilation path 3, it is not necessary to install a damper plate on the upstream side of the back movable louver 8, and the space for it is reduced. Thus, the case body of the register can be reduced in size. In addition, the number of parts such as a damper plate can be reduced.

  In the above embodiment, in the case body 1 having the horizontally long air outlet 2 and having a vertically short shape, the front fins 51 of the front movable louver 5 are arranged in parallel in the vertical direction as shown in FIG. The rear fins 81 of the rear movable louver 8 are arranged along the horizontal horizontal direction, but they are rotated 90 degrees, the case body is formed in a vertically long shape, and a vertically long slit-like air outlet is provided. Provided on the case body, the front fin of the front movable louver is arranged along the horizontal horizontal direction, which is the short direction of the air outlet, and the rear fin of the inner movable louver is along the longitudinal direction, which is the longitudinal direction of the air outlet It can also be provided. In this case, the ridges on the inner side of the air outlet are provided in the longitudinal direction along the longitudinal direction of the air outlet.
