Description

Indoor unit of air conditioner

The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner having a door assembly capable of moving the door cover in a vertical direction to open and close the front discharge port.

The separate air conditioner may include an indoor unit disposed indoors, an outdoor unit disposed outdoors, and cool, heat, or dehumidify the indoor air through a refrigerant circulating in the indoor unit and the outdoor unit.

The indoor unit of the separate air conditioner includes a stand type indoor unit installed upright on the indoor floor according to the installation form, a wall-mounted indoor unit installed on the indoor wall, and a ceiling type indoor unit installed on the indoor ceiling.

In the indoor unit of the conventional separate air conditioner, since the indoor fan is disposed in the cabinet, there is a problem that air-conditioned air cannot be discharged to a long distance.

Korean Patent No. 10-1191413 has been provided with a circulator for flowing the air around the indoor unit at a long distance.

However, although the air circulator described in Korean Patent No. 10-1191413 is installed in the indoor unit, the air circulator does not directly flow the air conditioner, but provides a function of flowing the indoor air above the indoor unit at a long distance.

Since the air circulator does not directly flow the air-conditioned air, the air circulator cannot supply the air-conditioned air to the target area, and thus, there is a problem in that the air-conditioned target area cannot be selectively air-conditioned.

On the other hand, Korean Patent Laid-Open No. 10-2017-0010293 has an opening formed in a cabinet of an indoor unit, and a door unit for opening and closing the opening is disposed. The door unit of Korea Patent Publication No. 10-2017-0010293 is movable in the front-rear direction and blocks the opening when the indoor unit is not in operation, and the door unit is moved forward to open the opening when the indoor unit is in operation.

However, Korean Patent Laid-Open No. 10-2017-0010293 (hereinafter referred to as Prior Art 1) opens and closes the opening by moving the door unit forward and backward, but is discharged through the opening because the door unit is located in front of the open opening. There is a problem that impedes the flow of air. That is, opening of the opening by the door unit of the prior art 1 is not suitable for flowing air at a long distance.

In addition, Korean Patent Laid-Open No. 10-2017-0010293 (hereinafter referred to as Prior Art 2) only advances the door to open the opening, and since the blower fan is located inside the outer panel, the air flowed by the blower fan appears. It generates resistance with the structure inside the panel, which causes a lot of flow loss in flowing air at a long distance.

On the other hand, the Chinese Utility Model 203375535 U (hereinafter referred to as prior art 3) discloses a structure capable of rotating the axial fan within a predetermined angle range. However, in the axial fan of the prior art 3, since both sides of the axial fan are fixed to the rotating shaft, only the motion of rotating based on the rotating shaft disposed on both sides can be realized. Prior art 3 has a problem in that it is not possible to rotate the axial flow fan in other directions not provided by the rotation shaft. That is, the prior art 3 has a problem in that it is rotatable only in the vertical direction provided with the rotating shaft or rotates only in the left and right directions.

When the door cover assembly is moved in the up and down direction, since both the left and right sides are supported by two gear driving motors, the door cover assembly is moved up and down, thereby minimizing operation noise due to the difference in movement distance between both sides of the door cover assembly.

Through the vertical movement of the door cover assembly, since the door cover assembly is hidden inside the door assembly, it is possible to minimize the front and rear thickness of the door assembly.

The fan housing assembly penetrates through the front discharge port of the door assembly and protrudes out of the door assembly, thereby minimizing the moving distance of the fan housing assembly.

In the projection state, since the door cover assembly is located under the fan housing, the moving distance of returning the door cover assembly to the front discharge port can be minimized.

When the front discharge port is closed, the door cover assembly is located in front of the steering grill, it is possible to minimize the moving distance of the fan housing assembly.

Since the first ball hinge 3610 and the second ball hinge 3620 may be rotated independently of each other, the first ball hinge 3610 and the second ball hinge 3610 may correspond to the tilting of the steering grill 3450.

The remote fan assembly 400 provides a projection state further drawn forward than the front surface 200a of the door assembly 200 through the front discharge port 201. The direction of the steering grill 3450 is steered in the projection state.

In the projection state, the front end 3502a of the steering grill 3450 protrudes more than the front surface 200a of the door assembly 200, and the front end 3452a of the steering grill 3450 and the front surface of the door assembly 200. 200a forms a protruding length P. That is, the protruding length P may be half of the thickness of the front and rear direction of the steering grill 3450.

When in the projection state, half of the outer surface 3651 of the steering grill 3450 is located outside the front discharge port 201, and the other half is located inside the front discharge port 201.

In particular, when the projection state, the outermost (3451a) of the outer surface (3451) of the steering grill (3450) is disposed on the same line as the front discharge port 201 or the front surface (200a) of the door assembly 200. It is preferable.

At this time, the steering cover 3454 of the steering grill 3450 forms an angle of 15 degrees with respect to the central axis C1. The steering angle of the steering grill 3450 may be controlled according to the moving distance of the moving rack 1020.

The relationship between the steering direction of the steering grill 3450, the moving rack 1020 of the first steering assembly 1001, and the moving rack 1020 of the second steering assembly 1002 is as follows.

Table 1

When the steering grill 3450 is steered to the left with respect to the central axis C1, only the second steering assembly 1002 is operated in this embodiment. The moving rack 1020 of the first steering assembly 1001 is positioned at an initial position, and the moving rack 1020 of the second steering assembly 1002 is backward. In this case, the steering grill 3450 is rotated to the left about the joint assembly 1100.

When the steering grill 3450 is steered to the right with respect to the central axis C1, only the second steering assembly 1002 is operated in this embodiment.

The moving rack 1020 of the first steering assembly 1001 is positioned at an initial position, and the moving rack 1020 of the second steering assembly 1002 is advanced. In this case, the steering grill 3450 is rotated to the right about the joint assembly 1100.

When the steering grill 3450 is steered upward with respect to the central axis C1, only the first steering assembly 1001 is operated in this embodiment.

In the projection state, the moving rack 1020 of the first steering assembly 1001 is reversed, and the moving rack 1020 of the second steering assembly 1002 is positioned at an initial position. In this case, the steering grill 3450 is rotated upward with respect to the joint assembly 1100.

When steering the steering grille 3450 downward with respect to the central axis C1, in this embodiment, only the first steering assembly 1001 is operated.

In the projection state, the moving rack 1020 of the first steering assembly 1001 is advanced and the moving rack 1020 of the second steering assembly 1002 is positioned at an initial position. In this case, the steering grill 3450 is rotated downward about the joint assembly 1100.

That is, when steering the steering grille 3450 upward, downward, leftward or rightward with respect to the central axis C1, in the present embodiment, the first steering assembly 1001 or the second steering assembly 1002 is used. Only one works.

Next, when steering the steering grille 3450 diagonally with respect to the central axis C1, both the first steering assembly 1001 and the second steering assembly 1002 are operated.

For example, when steering the steering grill 3450 in the lower left diagonal direction with respect to the central axis C1, in the projection state, the moving rack 1020 of the first steering assembly 1001 is advanced and the The moving rack 1020 of the second steering assembly 1002 is reversed. In this case, the steering grill 3450 is rotated to the lower left side about the joint assembly 1100.

When the steering grill 3450 is steered in a diagonal direction in the upper right side with respect to the central axis C1, the moving rack 1020 of the first steering assembly 1001 is reversed and the second steering assembly 1002 The moving rack 1020 is advanced.

Although not shown, when the steering grill 3450 is steered in the upper left diagonal direction with respect to the central axis C1, the moving rack 1020 of the first steering assembly 1001 is reversed, and the second steering assembly is rotated. The mobile rack 1020 of 1002 is reversed.

Although not shown, when the steering grill 3450 is steered in a diagonal direction in the lower right side with respect to the central axis C1, the moving rack 1020 of the first steering assembly 1001 is advanced and the second steering assembly is rotated. The moving rack 1020 of 1002 is advanced.

6 to 11 illustrate the maximum movement of the moving rack 1020 of the first steering assembly 1001 or the moving rack 1020 of the second steering assembly 1002.

The degree of steering may be adjusted by adjusting the forward or backward distance of each of the moving racks 1020.

In addition, the steering assembly 1000 according to the present exemplary embodiment immediately steers when the steering assembly 1000 is switched from each steering state to any other steering state.

When steering is changed from the left steering of FIG. 6 to the right diagonal direction of FIG. 11, the moving rack 1020 of the first steering assembly 1001 is retracted from an initial position, and the second steering assembly 1002 is moved. The rack is advanced in the reverse position.

As such, the steering assembly 1000 according to the present exemplary embodiment has an advantage of allowing the steering grill 3450 to immediately change steering from the current steering direction to the target steering direction.

Since the steering grill 3450 can be steered immediately, even if the indoor target area is changed in real time, direct wind can be provided to the target area.

For example, if the location of the occupants is determined in real time through the camera module, and the direct wind tracking mode is selected, direct wind may be provided to the occupants even if the occupants move indoors.

On the contrary, when the direct wind avoidance mode is selected, the direct wind can be provided to avoid the position where the occupants are located in the region where the temperature difference between the target temperature and the indoor temperature is large.

<Projection Status and Steering Status>

In order to provide the projection state in this embodiment, the advance distance of the fan housing assembly 3400 by the actuator 3470 is 80 mm.

In the projection state, the front end 3450a of the steering grill 3450 protrudes forward than the front surface 200a of the front panel 210. In this embodiment, the protruding length Q is 30 mm.

The front surfaces of the door assembly 200 and the cabinet assembly 100 should be spaced at least a predetermined interval (2 mm in this embodiment). Since the fan housing assembly 3400 is to be located a predetermined distance behind the front surface of the cabinet assembly 100, the front and rear thicknesses of the door assembly 200 should be substantially less than 298 mm.

In the projection state, the steering grill 3450 is preferably located at the front surface 200a in the front-rear direction. Thus, the front and rear lengths of the outer surface 3651 of the steering grill 3450 may be 60 mm. The length of the outer surface 3451 of the steering grill 3450 is 68 mm, and the radius of curvature of the outer surface 3651 is 152.5 degrees. When viewed from the side cross-section, the outer surface of the steering grill 3450 may be formed of a portion of the concentric circles around the radius of curvature.
