The present invention relates to a wind direction change device for an air conditioner that performs air conditioning.

Conventionally, in the indoor unit of a wall-mounted type separate air conditioner used for home use, the wind direction changing device is formed by combining the up and down flaps for setting the wind direction in the up and down direction, and the left and right flaps for setting the wind direction in the left and right directions, and arranging them in the air vent of the indoor unit. .

There are a method of operating the upper and lower flaps by fixing the left and right flaps attached to the air passage, and a method of changing the position of the left and right flaps in conjunction with the operation of the upper and lower flaps.

In the method in which the left and right flaps are fixed, the left and right flaps are fixed to the upstream side of the air passage to allow the air to be changed left and right, and the upper and lower flaps are provided on the downstream side thereof. In this case, generally, the structure which can connect the some blade which comprises a left-right flap using a connection member, and can direct a some wing | blade in the same direction by changing the direction of a some wing | blade is used.

On the other hand, in the method of changing the position of the left and right flaps in conjunction with the operation of the upper and lower flaps, the left and right flaps are attached to the upper and lower flaps fixed to the air vents, and when the wind direction is changed upward, the left and right flaps are positioned downstream of the air passage, When changing to the direction, the left and right flaps are comprised so that the air flow path may be located upstream. Also in this case, in the left and right flaps, a plurality of left and right wings are connected by a connecting member.

By the way, the conventional wind direction change apparatus of the air conditioner had the following problems. That is, in the manner in which the positions of the left and right flaps are fixed, the left and right flaps are always arranged upstream of the air passage of the blower regardless of the operation of the up and down flaps, so that the blowing resistance increases and the wind direction changing effect is small. . In addition, in the method of attaching the left and right flaps to the upper and lower flaps and changing the position of the left and right flaps in conjunction with the operation of the upper and lower flaps, when the upper and lower flaps are upward, the left and right flaps are largely extended to the upper portion of the tuyeres with the rotation of the upper and lower flaps. As a result, a blowing area in which the left and right flaps do not exist in the lower part of the tuyere is generated. Therefore, especially in a state where the airflow amount is small during the cooling operation, since the cold air that has cooled has a large specific gravity, most of the airflow passes through the lower portion of the tuyeres, and it is difficult to divide the cold air from side to side, thereby deteriorating the wind direction change effect.

An object of the present invention is to provide an air conditioner change device for an air conditioner, in which the left and right flaps are always moved to the mainstream of the blower in association with the operation of the upper and lower flaps, thereby improving the wind direction change effect. will be.

In order to solve the said subject, the airflow direction changing apparatus of the air conditioner of this invention is a blowhole which consists of a heat exchanger and a blower fan, the fan case installed downstream of the blower fan, and the up-and-down flap which changes the wind direction installed in the blowerhole up and down. And a left and right flap for changing the wind direction from side to side, and in conjunction with the up and down rotation of the up and down flaps, the left and right flaps are configured to be moved upstream or downstream in the blowing direction in parallel with the fan case of the air outlet.

With this configuration, in conjunction with the upper and lower flaps, since the left and right flaps are always located at the mainstream of the blower, a portion where the wind does not strike the left and right flaps is not generated in the lower portion of the blower port, so that the right and left supply of the wind is secured. In addition, even when the top and bottom flaps are fully opened, the left and right flaps are arranged to move in the direction where the wind blows, so that the air passage resistance can be reduced and the wind direction change effect can be improved.

In addition, the left and right flaps provided with a plurality of left and right wings having a wing shaft, a plurality of left and right wings rotatably supported in the left and right direction by the wing shaft, and a support having a support axis of rotation in a predetermined portion, and extending from the upper and lower flaps, And a support arm provided with a support hole for rotatably supporting the support shaft rotating shaft of the support.

With this configuration, the left and right blades are rotatable in the left and right directions, and the support of the left and right flaps rotates in the support holes even when the upper and lower flaps are operated in the vertical direction through the rotating shaft provided on the support arm. Do not move. As a result, the position of the left and right flaps in the tuyere is stabilized, and the wind direction changing action can be improved.

Moreover, it is a structure provided with the coupling shaft which extends from the support body at predetermined distance with the support shaft rotation axis of a support body, and the guide arrange | positioned at a ventilation port and hold | maintains a coupling shaft so that a movement is possible.

With this configuration, when the upper and lower flaps operate in the vertical direction, the left and right flaps can move along the guide groove while interlocking with the support arms provided on the upper and lower flaps. As a result, by making the shape of the guide groove similar to the shape of the lower surface of the fan case, it is possible to move parallel to the fan case and further improve the wind direction changing effect.

In addition, since the left and right flaps are configured to connect a plurality of left and right wings together and rotate in the same direction, the direction change of the left and right wings can be changed by changing one of the left and right wings.

As shown in the figure, the upper and lower flaps 12 are a plurality of support arms 25-which are provided at a predetermined position on the lower surface side of the upper and lower wings 24 having a horizontally long flat plate shape and the upper and lower wings 24. 1, 25-2). Support arms 25-1 and 25-2 are provided with support holes 26 with an open front, and are located at support arms 25-2 located at both ends of the upper and lower flaps 12, and at the center portions. The support arms 25-2 are provided with rotation shafts 27 that are spaced apart from the support holes 26 by a predetermined distance toward the outside, respectively.

A pair of left and right flaps 13 are assembled to the upper and lower flaps 12 to complete the wind direction changing device 11, and FIG. 3 shows the right half of the wind direction changing device 11. Therefore, the upper and lower blades 24 of the upper and lower flaps 12 are cut and shown in the center, and the rotating shaft 27 provided on the support arm 25-2 is also cut and shown.

The center stage 28 is arrange | positioned by being fixed to the stabilizer 3 in the left-right direction center part of the tuyeres 10. In the center stand 28, a coupling hole 29 for rotatably supporting the rotation shaft 27 provided on the support arm 25-2 positioned at the center of the upper and lower flaps 12, and a coupling shaft provided in the support stand 15. A bow-shaped guide groove 30 to which the 23 is coupled is formed. The rotating shaft 27 is rotatably coupled to the coupling hole 29 to support the rotation of the upper and lower flaps 12, and the coupling shaft 23 is movably coupled to the guide groove 30 to engage the support 15. The shaft 23 is configured to be movable along the guide groove 30. In the present embodiment, the guide groove 30 is used, but may be a through hole, a groove, a guide bar, or the like for guiding the movement of the coupling shaft 23.

Next, the assembling of the wind direction changing device 11 and the assembling to the air vent 10 will be described with reference to the drawings. First, as shown in FIG. 3, the pair of left and right flaps 13 blocked and assembled in the state shown in FIG. 2 is supported by the support arm of the upper and lower flaps 12 with the support rotation shaft 21 provided on the support 15. The wind direction changing device 11 consisting of the upper and lower flaps 12 and the left and right flaps 13 is completed by inserting and engaging the support holes 26 provided in the 25-1 and 25-2.

Next, the wind direction changing device 11 is inserted into the air vent 10 of the air conditioner. At this time, the rotating shaft 27 provided in the support arm 25-2 of the center part as shown in FIG. 4 is rotatably engaged with the engaging hole 29 provided in the center stand 28, and also the engaging shaft 23 is carried out. ) Is inserted into the guide groove (30).

Moreover, the rotating shaft 27 provided in the support arm 25-2 on the opposite side to the center stand 28 of the up-and-down flap 12 is an axial hole (not shown) provided in the side wall 9 of the left and right sides of the tuyere 10. It is inserted into and rotatably axially supported.

In addition, the wind direction changing device 11 is connected to a rotation shaft of a drive motor made of a stepping motor on either of the rotation shafts 27 on both the left and right ends of the upper and lower flaps 12 so as to automatically rotate in the vertical direction.

In addition, the operation | movement of the wind direction change apparatus by the said structure is demonstrated using FIGS. 5A-5C.

5A to 5C show the operating conditions of the wind direction changing device 11. 5A shows a state where the upper and lower flaps 12 are closed, FIG. 5B shows a state where the upper and lower flaps 12 are opened to the middle, and FIG. 5C shows a state where the upper and lower flaps 12 are fully opened.

The air conditioner is in a closed state as shown in FIG. 5A in the stopped state, and is controlled from the middle state of FIG. 5B to the fully open state of FIG. 5C up and down in order to control the cold wind blown upward during the cooling operation. I'm shaking. On the other hand, in the heating operation state, the first operation is performed for a while in the fully open state shown in Fig. 5C, and during the stable operation, the intermediate air in Fig. 5B is set in order to control the blowing air in the downward direction.

At this time, as the upper and lower flaps 12 open in the upward direction, the left and right wings 14 of the left and right flaps 13 are substantially parallel to the fan case 2 near the tuyeres 10, as indicated by the arrow A. FIG. It moves from the upstream side to the downstream side while moving downward to maintain the distance d with the fan case 2 as indicated by arrow B. FIG. At this time, the movement distance of the left and right flaps 13 is adjusted by the distance between the rotation shaft 27 of the support arm 25-2 and the support hole 26 shown in FIG. 3, and in this embodiment, the upper and lower flaps 12 ) Is set to a distance at which the left and right flaps 13 do not deviate from the air passage 6, even when the) is fully open.

In addition, the operation | movement of the left and right wing | wing 14 of the left-right flap 13 is a distance of the support shaft rotation axis 21 of the support stand 15 and the engagement shaft 22, and the attachment angle of the engagement member 22 to the support stand 15. It is regulated by the shape of the guide groove 30. That is, when the up-and-down flap 12 is made upward, each support arm 25-1, 25-2 rotates around the rotating shaft 27, and the left-right flap 13 inserted in the support hole 26 is carried out. ) Moves to the downstream side in the blowing direction while rotating the support axis of rotation (21) of the support (15). The coupling shaft 23 extends through the coupling member 22 on the support rotation shaft 21, and the coupling shaft 23 also moves downstream in the blowing direction with the movement of the support rotation shaft 21. Coupling shaft 23 is coupled to the guide groove 30 installed in the center stage 28 is moved along the shape of the guide groove (30). Accordingly, the left and right wings are controlled by controlling the movement position of the left and right flaps 13 by the shape of the guide groove 30, and the shape of the left and right wings 14 moves substantially in parallel with the fan case 2. (14) can be moved downstream in the blowing direction in parallel with the fan case (2). In addition, these parts can be realized by assembling resin molded parts and the like, and can be realized by a simple configuration without increasing the number of parts. Therefore, assembly can be simplified and manufacturing costs can be reduced.

According to the above configuration, regardless of the opening degree of the upper and lower flaps 12, the left and right wings 14 can always be located in the mainstream portion of the air passage 6 in front of the wind power outlet. Change is certainly done. In particular, even when the upper and lower flaps 12, such as at the time of weak blowing in the cooling operation, are completely opened, the left and right wings 14 of the left and right flaps 13 are located in the air passage 6 without deviating from the air vent 10. , The air blowing always hits the left and right wings 14, the wind direction change effect is made sure, efficient cooling operation can be made. Moreover, even if the up-and-down flap 12 operates up and down, since the left-right flap 13 is located in the main part of the air flow path 6, stable operation can be implemented without a sudden change of air flow resistance.

In addition, in the present embodiment, the shape of the guide groove 30 and the length of the coupling member 22 or the support 15 of the left and right wings 14 of the left and right flaps 13 are moved in parallel with the fan case 2. Although the attachment angle between the shaft and the coupling member 22 is set, it can be freely changed by the shape of the ventilation passage 6 formed by the stabilizer 3 and the fan case 2 or the like.

In the present embodiment, the coupling shaft 23 and the guide groove 30 are described as a means for moving the left and right wings 14 of the left and right flaps 13 to an optimal position in the blowing direction. It is good also as a structure which slides using a means, for example a cogwheel.

In addition, although the coupling shaft 23 and the guide groove 30 were arrange | positioned in the center part of the tuyeres 10 in this embodiment, this part may be arrange | positioned at the side wall 8 side of the both ends of the tuyeres 10. .

In addition, in this embodiment, although the up-down flap 12 was demonstrated by the structure which automatically rotates to a vertical direction by a drive motor, you may rotate manually without using a drive motor. In addition, although the left and right wings 14 of the left and right flap main body l3 were also demonstrated to be connected by the connecting rod l6 for rotating by interlocking from side to side, each left and right wing | wing independently was not used without the connecting rod 16. You may rotate (14).

As described above, according to the present invention, the left and right flaps are always moved upstream and downstream of the blower in parallel with the fan case of the blower in conjunction with the up and down rotation of the up and down flaps, so that the left and right flaps are always the mainstream of the blower. Move to negative position. As a result, the left and right sides of the blower can be surely provided without causing a portion that does not hit the left and right flaps in the lower portion of the blower port, thereby improving the wind direction changing effect and stabilizing the blower.

Moreover, according to this invention, the operation | movement of the left-right flap which interlocks with an up-and-down flap can be arbitrarily realized by combination of member shapes, and can be set freely according to the shape of a ventilation path.

In addition, since the assembly of these members can be realized by the configuration of joining the resin members, the assembly can be simplified and realized at low manufacturing cost without increasing the number of parts.
