Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner having left and right wind direction plates at an outlet.

  Conventionally, an air conditioner having left and right wind direction plates at the air outlet of the air passage, for example, the front end side of the left and right wind direction plates is made of a soft material so that it can be deformed in an arc shape in the left and right direction. There is known one that can smoothly change the blowing direction of the blown air left and right by curving the side to the left and right (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 2-76512 (FIGS. 1 to 5)

  As described above, the conventional air conditioner can deform the front end side of the left and right airflow direction plates in the left-right direction into an arc shape, so that the flow can be bent left and right in a smooth arc shape with a small resistance. However, since the length along the wind flow direction of the left and right wind direction plates is constant, it is necessary to reduce the radius of the arc in order to expand the range of change of the wind direction (widen the blowing wind direction in the left and right direction). In that case, the wind path resistance becomes large and the air does not flow smoothly, and the blowing wind speed does not increase. Such a problem can be improved if the rear end side of the right and left wind direction plates can be formed of a soft material, but is difficult in manufacturing.

  The technical problem of the present invention is to facilitate manufacture, to widen the blowing air direction without increasing the air path resistance, and to increase the blowing air speed.

Air conditioner according to the present invention, a plurality of installed air outlet air passage, the air conditioner having a wind horizontally directing plate which controls the wind direction sent out from the air outlet to the outside, on the windward side of the wind horizontally directing plate The auxiliary left and right wind direction plates are provided to direct the wind carried in the air path toward the left and right wind direction plates, and the plurality of left and right wind direction plates are rotatably attached to the base, and each left and right wind direction plate attached to the base The windward side end portion is connected to a connecting member that constitutes a link mechanism together with the base so as to be interlocked, and the auxiliary left and right wind direction plates are fixed to the connecting member .

  In the air conditioner according to the present invention, the auxiliary left and right wind direction plates provided on the windward side of the left and right wind direction plates are easy to manufacture. In addition, this auxiliary left and right wind direction plate can direct the wind that is carried in the wind path to the left and right wind direction plate, so that the blowing wind direction can be widened and the blowing wind speed can be increased without increasing the wind path resistance. Thus, even if the number of rotations of the blower is small, the wind can be blown away.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing an overall configuration of a main body of an air conditioner according to an embodiment of the present invention, FIG. 2 is a sectional view of the main body in side view, FIG. 3 is a perspective view showing a drain pan assembly, and FIG. 3 is an enlarged view of the left and right wind direction plate assembly which is part A of FIG. 3, FIG. 5 is a bottom view of the left and right wind direction plate assembly when FIG. 4 is viewed from below, and FIG. 6 is the relationship between the wind direction plate and the flow of wind. It is a schematic diagram which shows schematically.

  The air conditioner of the present embodiment is installed on the wall of a room where the main body 1 is air-conditioned. As shown in FIGS. 1 and 2, the main body 1 includes a front panel 1a that covers the front and upper surfaces of the main body, a housing side surface portion 1b, and a housing back surface portion 1c. And the suction inlet 2 is formed in the upper surface part of the front panel 1a, Furthermore, the mesh-like filter 3 and the heat exchanger 4 which remove dust are arrange | positioned in the upstream of the cross-flow fan 5 which is a blower.

  As shown in FIG. 2, a drain pan assembly 6 having a shape extending near the impeller of the once-through fan 5 is provided below the heat exchanger 4. The drain pan assembly 6 separates the suction side flow path E1 on the upstream side of the impeller and the blowout side flow path E2 on the downstream side, and configures the front side of the discharge side flow path E2 from the impeller to the outlet 7. Thus, the water droplets dripped from the heat exchanger 4 can be temporarily stored. Moreover, the back side of the blowout side flow path E2 from the impeller to the blower outlet 7 is constituted by a spiral guide wall 8, and the guide wall 8 is integrated with the housing back face portion 1c.

  Further, as shown in FIGS. 3 to 5, a plurality of left and right wind direction plates 10 and a plurality of vertical wind direction plates 11 (FIG. 2) are attached to the outlet 7 of the outlet side flow path E2, that is, the lower part of the drain pan assembly 6. ing. Among them, the vertical wind direction plate 11 is configured to be removable from the drain pan assembly 6 so that cleaning can be easily performed.

  Further, the left and right wind direction plates 10 are rotatably attached to the base 12, respectively, and the windward end portions of the left and right wind direction plates 10 attached to the base 12 are connected to each other by the connecting members 13 that form a link mechanism together with the base 12. It is connected and can be linked.

  Further, the auxiliary left and right winds that are carried on the windward side of the left and right wind direction plates 10, that is, the connecting member 13, as shown in FIGS. 5 and 6, are directed toward the left and right wind direction plates 10. A wind direction plate 14 is fixedly installed. Two auxiliary left and right wind direction plates 14 are arranged for each left and right wind direction plate 10. These two auxiliary left and right wind direction plates 14 are set so that the distance between them becomes narrower toward the leeward side as shown in FIGS. 5 and 6 and the left and right wind direction plate connecting portions in the connecting member 13 are sandwiched. . As a result, the wind passing between the two auxiliary left and right wind direction plates 14 contracts toward the left and right wind direction plates 10 located on the leeward side, so that the flow velocity increases.

  Here, the auxiliary left and right wind direction plates 14 are set to the same specifications as the left and right wind direction plates 10 and are manufactured by integral injection molding. Thereby, it is not necessary to newly manufacture a mold for manufacturing the auxiliary left and right wind direction plates 14, and it is possible to suppress an increase in cost.

  In the air conditioner of the present embodiment configured as described above, the air sucked from the suction port 2 at the upper part of the front panel 1a is subjected to heat exchange by passing through the heat exchanger 4. Thereafter, the cross-flow fan 5 is rotated to be sent to the outside from the blowout port 7 toward the blowout direction controlled by the left and right wind direction plates 10 via the blowout side flow path E2. At that time, the wind that is carried in the air passage toward the air outlet 7 enters between the two auxiliary left and right wind direction plates 14 arranged on the windward side of the left and right wind direction plates 10 and passes between them. In the meantime, the flow velocity is increased by the contracted flow effect, and is further forced to the left and right wind direction plates 10. For this reason, it is possible to allow more wind to flow along the left and right wind direction plates 10 than in the past, to widen the blowing air direction without increasing the wind path resistance, and to increase the blowing wind speed. Even if the rotational speed of the blower is small, the wind can be blown away. On the contrary, in the case of the left and right wide blowing equivalent to the conventional case, the rotational speed of the blower can be reduced, and the amount of heat exchange can be reduced by the amount of air flow reduced, thereby saving energy.

  In the above-described embodiment, the case where two auxiliary left and right wind direction plates 14 are arranged for each left and right wind direction plate 10 has been described as an example. However, the present invention is not limited to this example. May be installed every other left and right wind direction plate 10, and one auxiliary left and right wind direction plate 14 may be arranged for each left and right wind direction plate 10. Even in such a case, the intended purpose can be achieved.
