Description

  The present invention relates to an air conditioner, and more specifically, it is possible to smoothly extend a short air passage with a simple configuration, and to improve the air blowing performance with a vertical wind direction plate having strength and easy movement. Related to the structure.

  As shown in FIG. 3 (A), a conventional air conditioner has an up-and-down air direction plate that increases the amount of air blown in a substantially horizontal direction so that air conditioning can be performed more effectively. A heat exchanger C and a blower fan D are provided in an air passage connecting the suction port A and the air outlet B, and at least one vertical wind direction plate E is pivotally supported by the air outlet B so as to be rotatable. In the air conditioner, the upper and lower wind direction plates E are provided before and after the air outlet B, and two upper and lower air direction plates E are provided, and the two upper and lower wind direction plates E are provided in association with each other and driven. When the two up-and-down wind direction plates E are rotated to a substantially horizontal position by the linkage means and the drive means, the lower up-and-down wind direction plate E is moved to the outlet B as shown in FIG. There is disclosed a configuration in which the rear guider F constituting the lower part is arranged substantially on the extension. (E.g., see Patent Document 1.).

  However, since the lower up-and-down wind direction plate E is partly formed in a substantially flat plate shape, as shown in FIG. Depending on the angle, the rear guider F cannot be extended smoothly, and the part has a steep angle or a stepped portion. Therefore, the rear guider F flows along the rear guider F. There was a possibility that air could not be smoothly deflected up and down and air blowing performance was deteriorated.

  Further, as shown in FIGS. 3 (A) to 3 (C), the two upper and lower airflow direction plates E have their respective width dimensions corresponding to the vertical dimension of the air outlet B shortened. The problem was that it was difficult to understand the movement. Thus, for example, in the case of a single vertical airflow direction plate, the cost can be reduced by reducing the number of members, while the width dimension corresponding to the vertical dimension of the outlet B is increased to increase the thickness dimension. Otherwise, there was a risk of insufficient strength.

  Alternatively, as shown in FIG. 4, the traveling direction of the front guide portion b that guides the conditioned air to the front lower side in the air flow path a, as conditioned air can reach all corners of the room and can reduce noise. Wind direction variable portions c and d that change the wind direction in the front are provided, and the static pressure distribution in the vicinity of the wind direction variable portions c and d when the conditioned air is sent out from the outlet e directly downward or rearward and downward is the front guide portion b. The wind direction is variable so that it has a high static pressure part f higher than the static pressure, and the isostatic line of the high static pressure part f is formed along the flow direction of the conditioned air flowing facing the wind direction variable parts c and d. There has been disclosed a configuration in which the portions c and d are arranged and the air flow path a is extended by the wind direction variable portions c and d (for example, see Patent Document 2).

However, the wind direction variable parts c and d are arranged so that the isobaric lines of the high static pressure part f are formed along the flow direction of the conditioned air flowing facing the wind direction variable parts c and d. There is a problem that the structure becomes complicated due to the necessity of providing an arm portion g for rotating the wind direction variable portion c.

  Accordingly, the present invention has been made to solve the above-described problems, and the object thereof is to widen a short air passage smoothly with a simple configuration without gaps, and to make it easy to understand the movement during rotation. Even so, an object of the present invention is to provide an air conditioner provided with an up-and-down wind direction plate having a structure having strength to improve the air blowing performance.

  In order to achieve the above-described object, the present invention has the following characteristics in order to improve the air blowing performance by including an up-and-down air direction plate that can smoothly extend the air passage without gaps with a simple configuration.

A heat exchanger and a blower fan are provided in an air passage connecting the suction port and the air outlet, and a vertical air direction plate is pivotally supported by the air outlet, and the air outlet is closed when the vertical air direction plate is stopped. In an air conditioner that is opened during rotation,
The up-and-down wind direction plate is formed in an S-shaped cross section and is provided in the vicinity of a rear guider that constitutes the air outlet, and an auxiliary pivot part that is provided in the vicinity of a front guider that constitutes the air outlet. It is pivotally supported and has a convex surface portion projecting rearward at the lower portion close to the rear guider when stopped, and a convex surface portion projecting forward at the upper portion.

  According to the present invention, it is possible to smoothly extend a short air passage with a simple configuration without a gap, and includes an up-and-down wind direction plate having a configuration having strength even with a wide dimension in which movement at the time of rotation is easy to understand, An air conditioner that can improve the blowing performance can be provided.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory view of an air conditioner according to the present invention, (A) is an external perspective view, (B) is a cross-sectional view, and FIG. 2 is an explanatory view of a main part of the air conditioner according to the present invention. FIG. 4B is a cross-sectional view showing a state in which the air outlet is closed by the vertical wind direction plate when the operation is stopped, and FIG. 5B shows a state where the vertical wind direction plate is rotated to a substantially horizontal position around the pivotal support near the rear guider during the cooling operation. It is sectional drawing, (C) is sectional drawing which shows the state which rotated the up-and-down wind direction board to the substantially vertical position centering on the auxiliary | assistant pivot part of the front guider vicinity at the time of heating operation.

  As shown in FIGS. 1 (A) and 1 (B), an air conditioner according to the present invention has a heat exchanger 3 that exchanges heat between the suction air and an air passage that connects the suction port 1 and the air outlet 2; A blower fan 4 is provided for sending heat-exchanged air to the outlet 2.

  A left and right wind direction plate group 5 which is connected to each other and deflects the wind direction in the left and right direction is pivotally supported by the air outlet 2, and an upper and lower wind direction plate 7 which deflects the wind direction in the vertical direction is pivoted. It is supported.

  The up-and-down airflow direction plate 7 is pivotally supported by a pivotal support 6 provided in the vicinity of the tip of the rear guider 2a that constitutes the lower wall of the blower outlet 2. During the cooling operation, the pivotal support 6 is provided. By rotating to a substantially horizontal position about the center, the rear guider 2a has a function of extending the cold air in a substantially horizontal direction.

  The up-and-down wind direction plate 7 is pivotally supported by an auxiliary pivot portion 6 ′ provided in the vicinity of the front end portion of the front guider 2b that constitutes the upper wall of the outlet 2, and during heating operation, By rotating to the substantially vertical position around the auxiliary pivot 6 ', the front guider 2b is extended through the curved surface while being deflected in the substantially vertical direction, so that warm air can be blown downward. It has become.

  In order to reduce the size of the air conditioner, the air passage from the blower fan 4 to the air outlet 2 tends to be shortened, particularly when the thickness is reduced. By making it possible to extend the air passage easily and smoothly without increasing the number of components, the air blowing performance can be improved.

  Therefore, the up-and-down wind direction plate 7 is formed in an S-shaped cross section as shown in FIG. 1 (B), so that the rear guider 2a and the front guider 2b can be extended almost without gaps, and the outlet 2 The function is to provide a function that can smoothly deflect the wind direction in the vertical direction.

  Thereby, it becomes an air conditioner which can extend a short ventilation path without gap with a simple structure, and can improve ventilation performance.

  Moreover, the said up-and-down wind direction board 7 becomes the structure which strengthened intensity | strength by having been formed in the cross-section S character shape, and, by this, for example, it is necessary to provide several reinforcement ribs for reinforcing intensity | strength in a back surface As a result, the amount of material used can be reduced to reduce costs and weight.

  Further, since the vertical wind direction plate 7 is formed in an S-shaped cross section, the surface of the lower part shown in FIG. 1 (B) becomes concave, and the both sides of the blower outlet 2 are connected to the concave surface. By forming the surface of the front surface in a concave shape, it is possible to realize a design that makes it appear as if the entire portion has a slim feeling.

  Further, since the vertical wind direction plate 7 is formed in an S-shaped cross section, the light irradiated on the convex portion on the surface is easily reflected, but the concave portion is shaded. At the time of movement, the convex portions and concave portions on the surface can be identified at a glance, and the fact that they are rotating can be easily visually recognized.

  Next, based on FIG. 2 (A) thru | or FIG.2 (C), operation | movement of the said up-and-down wind direction board 7 is demonstrated below.

  When the operation is stopped, the vertical wind direction plate 7 closes the outlet 2 as shown in FIG.

  When the operation is stopped with the blower outlet 2 closed, the up-and-down wind direction plate 7 has a convex portion protruding rearward at the lower portion close to the rear guider 2a and protrudes forward at the upper portion close to the front guider 2b. This prevents the inside from being seen through the air outlet 2 and, as described above, a slim feeling across the lower surface of the up-and-down wind direction plate 7 and the surfaces of both sides thereof. Will be given.

  At the time of cooling operation, the up-and-down wind direction plate 7 rotates around the pivotal support portion 6 to open the outlet 2 as shown in FIG. Is brought close to the front end portion of the rear guider 2a constituting the blowout port 2, and the front end portion of the rear guider 2a is extended by the up-and-down airflow direction plate 7 with almost no gap to guide the blown air.

  At that time, since the up-and-down wind direction plate 7 has a convex portion protruding upward at the base end portion 7a close to the rear guider 2a, even if there is some variation in the angular range during rotation, The air can be extended so that the blown air flowing along the rear guider 2a can be smoothly guided.

  Further, since the up-and-down airflow direction plate 7 has a convex surface portion projecting upward at the base end portion 7a adjacent to the rear guider 2a and is formed in an S-shaped cross section, the base plate along the rear guider 2a. The blown air guided to the end portion 7a is efficiently blown out in a substantially horizontal direction while being deflected slightly upward as it goes from the base end portion 7a toward the tip end portion.

  Since the pivot 6 is provided in the vicinity of the tip of the rear guider 2a, the vertical wind direction plate 7 rotated to a substantially horizontal position during cooling operation has a base end 7a at the tip of the rear guider 2a. It will be close to without any gaps.

  At the time of heating operation, the up-and-down wind direction plate 7 rotates around the auxiliary pivot 6 ′ to open the outlet 2 as shown in FIG. By bringing 7a 'close to the front end portion of the front guider 2b constituting the blowout port 2, the front end portion of the front guider 2b is extended while being deflected downward by the vertical wind direction plate 7 substantially without any gap. It will be able to guide the blown air.

  At that time, the up-and-down wind direction plate 7 formed in an S-shaped cross section has a convex surface portion whose front surface protrudes forward at the base end portion on the side close to the front guider 2b. By the concave surface portion on the back surface side, the blown air flowing along the front guider 2b can be smoothly deflected downward.

  Further, since the vertical wind direction plate 7 is formed in an S-shaped cross section, the blown air guided to the base end portion on the side close to the front guider 2b along the front guider 2b While being deflected slightly forward as it goes from the end toward the tip 7a ′, it is efficiently blown down along the tip 7a ′.

  Since the auxiliary pivot 6 'is provided near the front end of the front guider 2b, the vertical wind direction plate 7 rotated to a substantially vertical position during the heating operation has a base end at the front guider 2b. It will be in close proximity to the tip of the tube with almost no gap.

  As described above, according to the present configuration, the short air passage can be smoothly extended without gaps with a simple constitution, and the air blowing performance can be improved. The air conditioner is provided with an up-and-down wind direction plate having the above-described configuration so that the blown air flowing through the blow-out port 2 can be effectively deflected.
