Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Field of Application) The present invention relates to a wind direction grill for an air conditioner, and in particular, it is possible to set the wind direction according to the model of the air conditioner, and also to set each grill plate. This invention relates to a wind direction grill for an air conditioner that can be integrally linked to adjust the wind direction.

(Prior Art) Generally, as an indoor unit of an air conditioner, a QlltI type as shown in the fifth prisoner is known.

This indoor unit main body 21 consists of a housing 22 and a front panel 23, and a suction port 24 in which vertical and horizontal bars are installed is provided at the upper front of the front panel 23. Further, a horizontally elongated air outlet 25 is provided at the lower part of the air inlet 24, and a wind direction grill 26 as shown in FIG. 6 is disposed inside this air outlet 25. This wind direction grill 26 is made up of a plurality of grill plates 27, 27 attached to the air outlet, and controls the direction of the blowing air such as cold air blown into the room from the heat exchanger 28 in the main body via the blower 29. It can be adjusted up, down, left and right.

FIG. 7 shows a part of this wind direction grill, in which a rotating pin 30 and a connecting pin 31 are formed at separate positions on the upper end of the grill plate 27, 27.

A rotatable cut portion 30a is provided at the tip of the rotary pin 30.
is formed so that it can be fitted into a mounting hole (not shown) in the upper frame of the air outlet. Therefore, this rotation pin 30 plays the role of a support shaft that supports the grill plate 27.

Further, as shown in FIG. 7, the connecting pin 31 has a connecting rod 32 that holds each grill plate 27 in parallel through the mounting hole 33.
The connecting rod 32 and the grill plates 27 and 27 form a parallel link.

As a result, by changing the direction of some of the grill plates, the entire wind direction of the grill can be changed to the same direction at once, and the wind direction can be adjusted easily and uniformly.

(Issue 8 to be solved by the invention) However, in the above-mentioned wind direction grill, each grill plate is oriented in parallel, so if the direction of the grill plate is changed and the air direction is largely deflected left and right, the ventilation area in the direction of air blowing increases. small(
There is a problem in that the ventilation resistance increases, the air volume decreases, and the wind noise increases.

Furthermore, when the amount of air blown is small, there is also the problem that the distance the air reaches is small and the cold air etc. cannot be sufficiently distributed indoors.

Furthermore, when expanding left and right, there is a dead zone at the end of each group of grill plates through which the air does not pass, and there is a possibility that the air blowing efficiency may decrease.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the problems of the conventional techniques described above, to easily set the wind from the outlet to expand or narrow it, and to easily adjust the direction of the entire wind direction grill. Our purpose is to provide a wind direction grill for air conditioners.

[Structure of the invention]

(Another Means for Solving the Problems) In order to achieve the above object, the present invention provides a structure in which a plurality of grill plates rotatably supported on a support shaft can be rotated by connecting pins formed on the grill plates. At least one or more straight lines connected to a connecting rod and connecting the connecting pin and the support shaft constitute a parallel link that integrally deflects and adjusts the grille plate. The connecting pin is formed at a position eccentric from the grill plate so that the grill plate is eccentric from the straight line forming the parallel link.

(Function) According to the present invention, a plurality of grill plates rotatably supported on a support shaft are rotatably connected to a connecting rod by a connecting pin formed on the grill plate, and the connecting pin and the above-mentioned At least two or more straight lines connecting the support shaft and the connecting rod constitute a parallel link that integrally deflects and adjusts the grille plate, and at least one or more grille plates constitute the parallel link. The connecting pin is formed at a position eccentric from the grill plate so that it is eccentric from the straight line, so that the air sent from the outlet can be spread over a wide area, or when the air volume is low, it can be narrowed down. The wind direction grills can be arranged to extend the distance, and the orientation of each grill plate can be adjusted in conjunction with each other.

(Embodiment) An embodiment of the wind direction grill for an air conditioner according to the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1.2.3 indicates a grill plate, and this grill plate 1.2.3 is rotated to the upper frame of the air outlet (not shown) by a rotation pin 4 having a structure similar to that of the conventional example. Possibly supported. A connecting pin 5 is formed at the upper end of the grill plate 1 at a position away from the rotation pin 4 and in the same plane as the thickness of the grill plate. Further, at the position where the connecting pin is attached at the upper end of the grill plate 2, an overhanging portion 2a is integrally formed toward the grill plate 1, and the connecting pin 5 is attached to the upper surface of the overhanging portion 2a on the thick part of the grill plate. It protrudes eccentrically by a predetermined amount from the center.

On the other hand, the grill plate 3 has an overhang 3 in a shape and position symmetrical to the overhang 2a of the grill plate 2 with respect to the plane of the grill plate.
A connecting pin 5 is also provided on the upper surface of the overhanging portion 3a and protruding from the thick portion of the grill plate by a predetermined amount.

Furthermore, the connecting pin 5.5 of the grill plate 1.2.3...
are fitted into mounting holes 7.7 bored in the connecting rod 6 at intervals equal to the mounting spacing of the rotation pins 4, whereby the grill plate 1.2.3 is fitted as shown in Fig. 2. As shown in , the outlet side is slightly expanded, forming a trapezoidal link as a whole.

At this time, each of the rotation pins 4.4 and the connecting pins 5.
5... and the longitudinal center line of the connecting rod 6 maintain a geometrically parallel positional relationship with each other, and constitute a parallel link.

Therefore, with this arrangement of the wind direction grill, the blowing air is blown out so that it spreads from side to side, and as a result, even when the indoor unit is installed on the wall in the longitudinal direction of the room, the blowing air such as cold air can be directed to the corner of the room. It can be sent to many people. Also,
Even if the tip of the air outlet is widened by the above-mentioned parallel link, the direction of each grill plate can be adjusted in an integrated manner by the link mechanism.

Next, a modification of the above-described embodiment will be described in which the grill plate 2 and the grill plate 3 are replaced to form a wind direction grill.

In FIG. 3, the grill plate 2 and the grill plate 3 are arranged interchangeably and connected by a connecting rod 6 to form a link. Incidentally, since the connecting rod 6 described above can be the same as that shown in FIG. 2, no additional parts are required.

According to this arrangement of the wind direction grill, the reach of airflow such as that sent from a so-called silent type air conditioner, which has a small air volume and a low wind speed, can be extended. Further, in this case, the airflow direction adjustment to the left and right using the grill plate can also be adjusted in an integrated manner using parallel links.

In the above embodiments, a wind direction grill having a symmetrical structure with respect to the grill plate 1 has been shown, but as another embodiment, a wind direction grill in which the eccentricity of the connecting pin provided on the grill plate gradually increases will be described.

Figure 4 shows a state in which grill plates with slightly different eccentricities of the connecting pins are connected using the connecting rod, and grill plates 8.9.10
The connecting pins are arranged so that the eccentricity of the connecting pins gradually increases.

For this reason, the interval between the two grill plates 9.10 on the right side is slightly wider than the interval between the grill plates 8.9 on the left side. By arranging the grill plate in this manner, it is possible to improve the sideward wind deflection characteristics while reducing the ventilation resistance at the wind direction grill.

In the above embodiment, a wind direction grill in which three grill plates are configured as one set of links has been described, but it is also possible to connect a larger number of grill plates provided with connecting pins having different eccentricities.

Further, in this embodiment, the rotation pin and the connecting pin are formed at the upper end as a support part of the grill plate, but this support part may be provided at the lower end of the grill plate or on both sides of the upper and lower ends. do not have.

Furthermore, in order to integrally deflect the wind direction grill to the left and right, instead of manually rotating one rotation pin using a drive motor built into the air conditioner, or rotating one rotation pin at one end of the connecting rod. It is also possible to add reciprocating motion, and in this case, it is also possible to adjust the wind direction using a remote control.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a parallel link is configured to integrally adjust the deflection of the grill plate via a connecting rod, and at least one grill plate constitutes the parallel link. Since the connecting pin is formed at a position eccentric from the grill plate so that it is eccentric from the straight line, a wide range of wind directions can be set depending on the model and application, and multiple grill plates can be linked together to easily adjust the wind direction. This has effects such as being able to make adjustments.
