Description

  The present invention relates to an air conditioner such as an air conditioner or an air purifier that has a wind direction control plate for wind direction control and needs to improve the reach distance of air blowing.

  Conventionally, in an air conditioner, for example, an indoor unit of an air conditioner, in order to change the wind direction in the vertical direction, one or two wind direction control plates called upper and lower blast plates are provided near the outlet.

  In order to improve the comfort of the customer's room where the air conditioner is installed, when cooling, the angle of the upper and lower honey is raised so that the cold air flows toward the ceiling and does not hit the customer directly To.

  In addition, during heating, the angle of the upper and lower honey is directed downward so that warm air flows toward the floor so that the entire room is warmed.

  In order to improve this function, for example, as disclosed in Patent Document 1, the rotation axis of the upper honey is provided at the upper limit of the outlet, and at the same time, the lower rotator is provided at the lower limit of the outlet. ing.

  By adopting such a configuration, as shown in FIG. 9 showing the conventional method during heating and as shown in FIG. 10 showing the conventional method during cooling, the air flow is changed by sandwiching the gas flow. (See Patent Document 1).

JP 2010-101504 A

  However, in the configuration described in the above-mentioned Patent Document 1, in both the warm and cool cases, the upper and lower lanes are deflected in the wind direction with respect to the main flow direction of the gas flow generated by the cross flow fan and the casing. Therefore, it is difficult to earn a large reach of the cooling air and the heating air.

  Further, when the state of the air flow with respect to the honey which becomes the draft resistance with respect to the main flow direction of the gas is observed in detail, the bending of the upper and lower honey is simplified with respect to the main flow direction 14 of the gas as shown in FIG. If the angle of the wind direction 15 to be set is the target angle 16, the entrance angle 17, the exit angle 18 and the target angle 16 are all the same angle, and since the angles are steep, peeling occurs on the back surface of the honey 19, The dynamic pressure loss of gas flow increases. As a result, the reach distance of the airflow passing through the rear surface of the honey 19 is particularly decreased, and it is difficult to earn a large reach distance of the cooling air and the heating air.

  The present invention solves the above-mentioned conventional problem, suppresses fluid separation on the back surfaces of the upper and lower honey, suppresses dynamic pressure loss of gas flow, makes it possible to greatly increase the reach distance of the gas, It aims at providing the air-conditioning equipment which can contribute to the improvement of comfort.

  In order to solve the above-described conventional problems, the present invention provides an air conditioner including a blowout channel and upper and lower hoods disposed at an outlet portion of the blast channel, wherein the upper and lower skirts are sub-flaps at a downstream end thereof. The sub-flaps have a chord length that is a quarter of the chord length connecting the upstream end and the downstream end of the upper and lower honey, and the upper and lower skirts and the sub-flaps are independent of each other. Thus, the configuration is operable.

  According to the above configuration, assuming that the angle of the wind direction to be bent with respect to the main flow direction of the gas flow is a target angle, first, the so-called entrance angle for tilting the upper splash angle with respect to the main flow direction is greater than the target angle. Arrange them to be smaller. Next, it is possible to arrange the sub flap connected to the upper frame so that the angle of the sub-flap is inclined with respect to the main flow direction so that the so-called exit angle is equal to the target angle. As a result, it is possible to suppress the fluid separation on the upper and lower back surfaces of the wafers, independently adjust the exit angle required for the wind direction by the sub-flap, and adjust the wind direction to the target angle. Since the chord length is one-fourth of the chord length connecting the upstream end and the downstream end of the upper and lower honeycombs, the flow friction resistance of the airflow due to the sub-flap can be minimized. That is, as compared with the conventional method, the dynamic pressure loss of the gas flow and the flow frictional resistance are suppressed, and it is possible to greatly increase the reach distance of the gas.

  The present invention suppresses the dynamic pressure loss and flow frictional resistance of the gas flow, makes it possible to greatly increase the reach distance of the gas, and can provide an air conditioner that improves the comfort of the living space.

  1st invention is an air-conditioning apparatus provided with the blowing flow path and the upper and lower honey-and-bowl arrange | positioned at the exit part of the blowing flow path, Comprising: The said upper and lower honey_wheel connects a subflap to the downstream end, This subflap The chord length that is a quarter of the chord length connecting the upstream end and the downstream end of the upper and lower honey is configured, and the upper and lower honey and the sub flap are configured to be independently operable. . According to the above configuration, assuming that the angle of the wind direction to be bent with respect to the main flow direction of the gas flow is a target angle, first, the so-called entrance angle for tilting the upper splash angle with respect to the main flow direction is greater than the target angle. Arrange them to be smaller. Next, it is possible to arrange the sub flap connected to the upper frame so that the angle of the sub-flap is inclined with respect to the main flow direction so that the so-called exit angle is equal to the target angle.

As a result, it is possible to suppress fluid separation on the back surfaces of the upper and lower honeycombs, and to independently adjust the exit angle required for the wind direction by the sub-flap so that the wind direction can be adjusted to the target angle. Since the chord length of the chord length connecting the upstream end and the downstream end of the upper and lower honey is a quarter of the chord length, it is possible to minimize the flow frictional resistance of the air flow caused by the sub-flap. That is, as compared with the conventional method, the dynamic pressure loss of the gas flow and the flow frictional resistance are suppressed, and it is possible to greatly increase the reach distance of the gas.

  According to a second invention, in the first invention, the upper and lower skirts are rotatably supported by a honey support shaft having one end portion on the upstream side connected to the drive shaft and the other end portion fixed to the blow-off passage. The sub-flap is rotatably supported at the outlet of the blow-off channel, and the sub-flap is pivotally supported on both sides of the downstream end of the upper and lower honey so that the sub-flap is rotatably connected to the upper and lower honey. Further, pulleys are attached and fixed to both the hook support shaft for supporting the upper and lower springs and the flap shaft of the sub-flap, and a power transmission member such as a wire is constructed so as to draw a figure 8 between the pulleys. Thus, the configuration is such that the upper and lower springs and the sub pulley are linked via the both pulleys.

  According to this configuration, when a driving device such as a motor is driven, the upper and lower honeys rotate around the rotation shaft, and the sub-flap provided on the downstream side of the upper and lower honeys is connected to the power transmission member such as a wire and each pulley. It rotates in conjunction with each other, and the vertical direction and the sub-flap are inclined at different angles to change the wind direction. At this time, the upper and lower honey pulleys are fixed to the blow-out flow path, and the upper and lower honey pulleys and the sub-flap pulley are such that a power transmission member such as a wire that links the two draws a figure of eight. Since it is inserted into the pulley, for example, in the case of upward airflow operation, if the upper and lower honey is upward, the sub-flap is further upward, whereas in the case of downward airflow operation, the sub-flap is further It goes down. This makes it possible to use only one drive device for increasing the gas reach distance, which can greatly contribute to cost reduction.

  According to a third aspect of the present invention, in the first or second aspect of the invention, a plurality of upper and lower honey with sub-flaps are arranged at the top and bottom at the outlet portion of the blowout flow path, and the wind direction is determined by the upper and lower honeys on the upper and lower sides. By controlling, the effect of the first invention can be further enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking as an example the case of application to an air conditioner. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a configuration diagram of an air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is an explanation showing the flow of gas by simplifying the upper and lower heaters of the air conditioner according to Embodiment 1.

  In FIG. 1, this indoor unit of an air conditioner includes a horizontally long crossflow fan 1, a heat exchanger 2 disposed so as to surround the crossflow fan 1, and a front tongue portion 3 adjacent to a front lower portion of the crossflow fan 1. The front-side casing 4 is provided, and the back-side casing 6 is provided with a back-side tongue portion 5 close to the back side of the cross flow fan 1. Further, the indoor unit 7 includes an upper and lower honey 10 at the outlet 9 of the blow-out flow path 8 constituted by the front casing 4 and the rear casing 6, and a sub-flap 11 at the downstream end of the upper and lower honey 10. Is connected. The upper and lower honeycombs 10 and the sub-flaps 11 are configured to rotate independently. Further, the sub-flap 11 has a chord length l that is a quarter of the chord length L connecting the upstream end and the downstream end of the upper and lower honey 10.

  In the above configuration, the flow of airflow in the air conditioner will be described with reference to FIG.

As shown in FIG. 2, when the angle of the wind direction 15 to be bent with respect to the main flow direction 14 of the gas flow is a target angle 16, first, an entrance angle 17 that tilts the angle of the upper and lower honey 10 with respect to the main flow direction. Is arranged to be smaller than the target angle 16.

  Next, the sub-flap 11 connected to the upper and lower honeycombs 10 can be arranged so that the angle of the sub-flap 11 is inclined with respect to the main flow direction 14 and the exit angle 18 is equal to the target angle 16.

  In this way, the gas flow is gently deflected, and the fluid separation on the back surface of the upper and lower honey layers, which has occurred in the conventional example shown in FIG. 10, can be suppressed. By adjusting independently by the flap 11, it becomes possible to adjust the wind direction to the target angle 16, and the gas can reach farther. Further, since the sub-flap 11 has a chord length that is a quarter of the chord length connecting the upstream end and the downstream end of the upper and lower susceptors 10, the sub-flap 11 is generated when the air flow is deflected by the sub-flap 11. Flow frictional resistance can be minimized. Accordingly, the effect of minimizing the flow frictional resistance is also added, so that it is possible to further increase the reach distance of the gas.

  FIG. 3 is a relational diagram showing the length Ld of the gas reaching distance to the ratio of the chord length l of the sub-flap 11 to the chord length L of the upper and lower honeycombs 10 shown in FIG. It is.

  As can be seen from this figure, by setting the chord length of the sub-flap 11 within the range of l0 <l <1 / 4L, it is possible to reach the maximum reach distance LdMax without substantially reducing the reach distance of the gas. It is possible to earn a large distance. As described above, the chord length l of the sub-flap 11 that greatly affects the gas blowing angle from the outlet 9 of the blow-out flow path 8 is less than or equal to ¼ of the chord length L of the upper and lower honey 10. Since the contact time and area of the gas deflected at 10 with the gas sub-flap 11 are small, the gas flow frictional resistance is also reduced. It can be done.

  As described above, the air conditioner of the present embodiment can suppress the dynamic pressure loss and the flow friction resistance of the gas flow, and can greatly increase the reach distance of the gas, as compared with the conventional method. .

(Embodiment 2)
4 is a configuration diagram of the air conditioner according to Embodiment 2, FIG. 5 is an exploded sectional view taken along line aa in FIG. 4, and FIG. 6 is a sectional view taken along line bb in FIG.

  In FIG. 4, this air conditioner includes an upper and lower honey 10 near the outlet 9 of the blowout flow path 8 of the indoor unit 7, and a sub-flap 11 on the downstream side of the upper and lower honey 10.

  In FIG. 5, the upper and lower honeycombs 10 are connected to a drive shaft 23 a from a drive device 23 such as a motor, which is fixed to the blowout flow path frame 22 on one side of the upstream rotation axis 21. Further, the other upstream end of the upper and lower honey 10 is rotatably supported by a honey support shaft 24 fixed to the blowout flow channel frame 22 and protruding from the blowout flow channel frame 22. And the bearing 26 which receives the flap axis | shaft 25 of the sub flap 11 is provided in the downstream both sides of the said upper / lower frame 10.

  On the other hand, the sub-flap 11 has a flap shaft 25 fixed on a rotation axis 27 on the upstream side thereof, and the flap shaft 25 is rotatably supported on a bearing 26 of the upper and lower honey 10. Free and rotatable.

  Here, a pulley 28 is attached to one side of the flap shaft 2 of the sub-flap 11, and the sub-flap 11 and the pulley 28 are fixed by a D-cut or the like so as to rotate together.

  On the other hand, a pulley 29 of the upper and lower honey 10 is fixedly attached to one of the honey support shafts 24 that pivotally support the upper and lower honey 10, and the pulley 29 is fixed to the blowout flow channel frame 22. It is in a fixed state without rotating with the rotation of the upper and lower honey 10.

  FIG. 6 is a cross-sectional view showing a cooperative configuration of the upper and lower honey 10 and the sub flap 11.

  In FIG. 6, the pulley 28 of the sub-flap 11 and the pulley 29 of the upper and lower slots 10 are connected by a power transmission member (hereinafter referred to as a wire) 30 such as a wire, and the wire 30 draws a figure of eight. Further, the pulley 28 and the pulley 29 are installed.

  In the air conditioner configured as described above, when the driving device 23 such as a motor is driven, the upper and lower honey 10 rotates about the honey shaft 24. Further, since the pulley 28 provided on one flap shaft 25 of the sub-flap 11 is fixed to the sub-flap 11, if the drive is transmitted to the pulley 28 by the wire 30, the sub-flap 11 is It will rotate centering on the bearing 26 with which it was equipped.

  Here, even if the upper / lower honey 10 receives a driving force in a certain rotation direction by the driving device 23, the pulley 29 of the upper / lower honey 10 does not rotate because it is fixed to the blowout flow channel frame 23 of the indoor unit body. In other words, when viewed from the upper and lower honey 10, the pulley 29 appears to rotate in the reverse direction relative to the rotation direction of the upper and lower honey 10.

  The pulley 29 of the upper and lower honeycombs 10 and the pulley 28 of the sub-flap 11 are connected by a wire 30, and the wire 30 is installed on the pulleys 29 and 28 so as to draw a figure 8, so that FIG. In the case of upward airflow operation (b), the sub-flap 11 is further upward when the upper / lower frame 10 is upward, and conversely, in the case of downward airflow operation (b), the upper / lower frame 10 is directed downward. The sub flap 11 will be further downward.

  This makes it possible to deflect the gas from the blowout flow path 8 in a desired direction, suppress the dynamic pressure loss and flow frictional resistance of the gas flow, and at the same time can greatly increase the reach distance of the gas, The upper and lower honey 10 and the sub-flap 11 can be driven with a single driving device 23, and the cost can be greatly reduced.

  In this embodiment, a wire is exemplified as the power transmission member 30 installed on each of the pulleys 28 and 29. However, this may be a timing belt or a rubber as long as it can transmit power. It ’s good.

(Embodiment 3)
