2. Description of the Related Art In an indoor unit of an air conditioner (hereinafter referred to as "air conditioner") that performs air conditioning in a room, the air in the room is sucked by the rotation of a fan such as a cross flow fan. The air sucked into the indoor unit passes through the heat exchanger and is blown out indoors as air-conditioned air. The fan provided in the indoor unit of such an air conditioner is provided close to the heat exchanger, and is long according to the length of the heat exchanger. Further, the rotating shaft of the fan is attached substantially parallel to the heat exchanger.

In an indoor unit of an air conditioner, indoor air is sucked in through a suction port provided in a grill provided on the front surface of the main body of the outdoor unit, and is blown out through a blowout port provided adjacent to the suction port. It has become. At this time, in order to make the indoor unit compact, air is inverted into a substantially U shape inside the indoor unit. For this reason, in the indoor unit, the heat exchanger is arranged obliquely, and a suction frame curved along the flow of air is provided on the suction side of the heat exchanger.

Further, in the indoor unit, the outlet side of the fan casing is formed in a duct shape in order to efficiently guide the air passing through the heat exchanger toward the outlet. The fan is arranged in the outlet side of the duct-shaped fan casing.

By the way, the air conditioner is classified into an exposed type such as a wall-mounted type which is exposed and mounted on the wall surface, and an embedded type which hides the indoor unit in the ceiling or the like.

By the way, the cross flow fan 30 is housed on the outlet side 34 of the fan casing which is formed in a duct shape from the heat exchanger 28 toward the grill 26.

As shown in FIG. 2 and FIG. 2, a fan accommodating portion 50 for accommodating the cross flow fan 30 is provided on the blowout side 34 of the fan casing. The fan housing portion 50 is formed with flange portions 100 and 102 that oppose both ends of the cross flow fan 30 in the axial direction, and has an upper portion formed in an arc shape in accordance with the outer shape of the cross flow fan 30. .

One flange portion 100 (specifically, FIG.
On the left side of the paper of FIG. 4), a bearing accommodating portion 54 in which a cylindrical recess is formed is provided (see FIG. 4A). FIG.
As shown in (A), a bearing member 64 is housed in the bearing housing portion 54. As shown in FIG. 6, in the bearing member 64, a bearing 74 is inserted at the center of a base portion 66 formed of an elastic member such as rubber in a substantially columnar shape.

As shown in FIGS. 3 (B) and 4 (A),
One rotation shaft 76A of the cross flow fan 30 is inserted into the bearing 74. By inserting this bearing member 64 into the bearing accommodating portion 54 on the blowout side 34 of the fan casing, the cross shaft 76A is crossed via the rotation shaft 76A. One end of the flow fan 30 in the axial direction is supported.

Further, as shown in FIG. 2, the fan housing portion 50 is provided on the other rotary shaft 76B of the cross flow fan 30.
The other flange portion 102 of the rotary shaft 76B corresponds to the opening portion 51 formed in the flange portion 102.
Is inserted. The drive shaft of the fan motor 36 is integrally rotatably connected to the rotary shaft 76B of the cross flow fan 30. That is, as shown in FIG. 4B, an engaging pin 78 that is orthogonal to the axial direction is provided on the rotary shaft 76B of the crossflow fan 30 so as to project from the rotating shaft 76B. The drive shaft is engaged and can rotate integrally. In addition, the cross flow fan 30
The fan motor 36 and the fan motor 36 are easily separated from each other by relatively separating them from each other along the axial direction.

The flange portion 10 of the fan accommodating portion 50 is also included.
Reference numerals 0 and 102 restrict movement of the crossflow fan 30 along the axial direction. By connecting the drive shaft of the fan motor 36 to the rotation shaft 76B, the crossflow fan 30 is provided in the fan housing portion 50 at a predetermined position. Is positioned at the position.

As shown in FIG. 1, the fan motor 36 is
It is attached to the casing 14 separately from the cross flow fan 30 via the motor retainer 80. Therefore, if the motor retainer 80 is removed, the connection between the fan motor 36 and the cross flow fan 30 can be released.

On the other hand, as shown in FIGS. 2, 4 (A) and 5, the outlet side 34 of the fan casing has a heat exchanger 28.
Side frame body 82 and the outlet frame 84 on the downstream side in the outlet direction. The frame main body 82 is arranged so as to extend from the heat exchanger 28 to the upper portion of the fan housing portion 50, and is fixed to the heat exchanger 28 and the casing 14. The frame main body 82 receives the air passing through the heat exchanger 28 from the upper part to the middle part of the fan housing part 50.
The duct for guiding toward the cross flow fan 30 is formed.

The outlet frame 84 is used for the fan housing section 5.
It is arranged from the lower part of 0 toward the open surface of the casing 14, and is detachably connected to, for example, the frame main body 82, the heat exchanger 28, the casing 14 and the like by screws or the like.

As shown in FIG. 3 (C), the outlet frame 84 has a substantially U-shaped plane by a guide plate 86 arranged on the opposite side of the heat exchanger 28 and a pair of legs 88A and 88B. The pair of legs 88A and 88B are respectively provided at their tips at both ends in the longitudinal direction of the heat exchanger 28. Therefore, the outlet frame 84 forms a duct with the heat exchanger 28 from the vicinity of the cross flow fan 30 toward the grill 26, and the heat exchanger 28
The air that has passed through the lower portion and the air delivered by the cross flow fan 30 are guided toward the room 18 along the guide plate 86.

Further, the flange portion 10 of the fan housing portion 50
Reference numerals 0 and 102 respectively denote the division parts 1 on the frame body 82 side.
00A and 102A, and the split portions 100B and 102B on the outlet frame 84 side. Along with this, the bearing accommodating portion 54 formed on the flange portion 100 is also divided.

The dividing parts 100B and 102B, which are divided on the side of the outlet frame 84, are the cross flow fan 30.
The flange portion 10 in a substantially fan shape with an angle θ around the axis of
It has a shape in which 0 and 102 are cut out (see FIG. 4B). Therefore, by removing the divided portion 100B of the flange portion 100 from the divided portion 100A, the bearing housing portion 54 is partially opened, but the base portion 6 of the bearing member 64 is formed.
The angle θ is set so that the opening width along the diametrical direction of 6 is shorter than the diameter dimension of the base 66. As a result, the bearing member 64 does not separate from the bearing housing portion 50 only by removing the outlet frame 84. That is, the cross flow fan 30 is prevented from being detached when the outlet frame 84 is removed.

By elastically deforming the base portion 66 of the bearing member 64, the rotary shaft 76A of the cross flow fan 30 is fitted into the bearing member 6 through the opening formed in the bearing housing portion 50.
It is designed so that it can be removed together with 4. Further, this allows the crossflow fan 30 to move along the axial direction, so that the rotation shaft 76B of the crossflow fan and the fan motor 36 are disconnected, and the crossflow fan 30 is removed from the fan housing portion 50. You can

It is needless to say that such an angle θ is not more than 180 degrees, and it is preferable that the angle is small so that the base 66 does not elastically deform and easily forms an opening that does not easily come out. In addition, it is preferable that the base portion 66 is suppressed within a range in which it can elastically deform. To this end, the base 66
The angle θ may be set in accordance with the elasticity characteristic of the base 66, or the material of the base portion 66 and the like may be selected so that the elastic force matching the angle θ can be obtained.

On the other hand, as shown in FIGS. 2 and 4 (A),
The lower end portion of the outlet frame 84 (the end portion on the side opposite to the arrow H direction, the end portion on the lower side of the paper surface of each drawing) is integrally formed with a part of the side plate 90 of the casing 14 that opposes the width direction (arrow W direction). Are linked to. In addition, the side plate 90 is the casing 14
It is removable from. As shown in FIG. 5, by removing the side plate 90 from the casing 14, a gap through which the outlet frame 84 and the cross flow fan 30 can pass between the ceiling plate 22 and the heat exchanger 28 at the peripheral edge of the opening 24. To be able to form.

As a result, in the indoor unit 12 of the air conditioner 10, the crossflow fan 30 can be removed from the casing 14 and pulled out by removing the outlet frame 84.

Next, the operation of this embodiment will be described.

Air conditioner 1 installed on the ceiling in the room
In the indoor unit 12 of 0, the crossflow fan 30 is driven to rotate by driving the fan motor 36,
The air is sucked into the casing 14 from a suction port (not shown) formed in the central portion of the grill 26. The air sucked into the casing 14 is guided to the heat exchanger 28 by the suction side 32 of the fan casing and passes through this heat exchanger 28. By the refrigeration cycle between the heat exchanger 28 of the indoor unit 12 and the outdoor unit, the suctioned air is conditioned.

The air that has passed through the heat exchanger 28 is guided to the blow-out side 34 of the fan casing by the rotation of the crossflow fan 30, and is sent out to the room 18 from the blow-out port (not shown) provided in the grill 26. This allows the air conditioner 10 to harmonize the air in the room 18.

Next, attachment / detachment of the cross flow fan 30 from the indoor unit 12 of the air conditioner 10 will be described.

To remove the cross flow fan 30 in the indoor unit 12 of the air conditioner 10, the drain pan 38 is removed after removing the grill 26. As a result, as shown in FIG. 3 (A), the heat exchanger 28 inside the casing 14 appears, and the outlet frame 84 below the outlet side 34 of the fan casing is provided between the heat exchanger 26 and the casing 14. Then, a part of the cross flow fan 30 appears between the outlet frame 84 and the heat exchanger 28.

In the next work, the outlet frame 84 is taken out. This outlet frame is made possible by releasing the engagement with the frame body 82, the heat exchanger 28, and the casing 14. As a result, the side plate 90 integrated with the outlet frame 84 can also be removed.

If the side plate 90 cannot be removed from the casing 14, the outlet frame 84 is pulled out from the narrow space between the casing 14 and the heat exchanger 28. It is difficult to remove the mouth frame 84. On the contrary,
In the indoor unit 12 of the air conditioner 10, the side plate 90 at the lower end portion of the casing 14 is integrated with the outlet frame 84 and can be removed from the casing 14. Therefore, the space between the casing 14 and the heat exchanger 28. Instead, the outlet frame 84 can be pulled out using a relatively large space between the heat exchanger 28 and the ceiling plate 22, which makes the work extremely simple.

In this way, by making a part of the casing 14 removable, it is possible to suppress interference with other parts when taking out the parts mounted inside the casing 14 from the inside of the casing 14 and to extremely suppress the parts. Can be easily removed.

In the blowout side 34 of the fan casing, by removing the blowout port frame 84, a part of the bearing accommodating portion 54 to which one rotating shaft 76A of the crossflow fan 30 is attached is opened. Since the opening width is smaller than the diameter dimension of the bearing member 66, the cross flow fan 30 does not come off in this state.

Next, when removing the cross flow fan 30, the base portion 66 of the bearing member 64 housed in the bearing housing portion 54 is elastically deformed, and the outlet frame 84 is formed.
The bearing member 64 is pulled out from the opening formed by removing the. The crossflow fan 30 attached to the bearing member 64 is also pulled out by the child, and if the rotation shaft 76B of the crossflow fan 30 is disengaged from the fan motor 36, the crossflow fan 30 is blown from the blowout side 34 of the fan casing. The flow 30 can be withdrawn.

That is, the cross flow fan 30 is rotated from the bearing housing 54 to the rotary shaft 76 of the cross flow fan 30.
By pulling out A, the cross flow fan 30 is pulled out from between the flange portions 100 and 102. As a result, the cross flow fan 30 can move along the axial direction, and the connection between the rotary shaft 76B and the fan motor 36 is released. At this time, since the fan motor 36 is attached via the motor retainer 80 separately from the crossflow fan 30, the fan motor 36 does not accidentally come off and fall off when the crossflow fan 30 is removed. . Further, since the fan motor 36 does not come off together with the crossflow fan 30, the removal of the crossflow fan is a light work requiring no labor.

After that, the crossflow fan 30 is to be pulled out from the inside of the casing 14. However, since the side plate 90 at the lower end portion of the casing 14 is removed integrally with the outlet frame 84, the crossflow fan 30 is fixed to the ceiling plate. Two
A relatively large space between 2 and the heat exchanger 28 can be used for withdrawal. When installing the cross flow fan 30, it may be carried out in the reverse order of removal.
In the indoor unit 12 of the air conditioner 10, the cross flow fan 3
Installation of 0 is also extremely easy.

As described above, in the air conditioner 10, the side plate 9 at the lower end portion of the casing 14 is integrated with the outlet frame 84.
By removing 0, it becomes extremely easy to take out not only the outlet frame 84 but also the crossflow fan 30 from the casing 14. In addition, in the indoor unit 12,
The outlet side 34 of the fan casing is divided into a frame body 82 and an outlet frame 84, and the outlet frame 84
The crossflow fan 30 can be easily pulled out from the blowout side 34 of the fan casing.

Further, the fan motor 36 does not come off when the cross flow fan 30 is removed. The fan motor 36 is heavier than the cross flow fan 30 and may be detached integrally with the cross flow fan 30.
If the fixation of the fan motor 36 becomes unstable by removing the cross flow fan 30, there is a possibility that a problem such as the fall of the fan motor 36 may occur. On the other hand, in the indoor unit 12 of the air conditioner 10, since the fan motor 36 is attached by the motor retainer 80 separately from the cross flow fan, the fan motor 36 does not accidentally come off.

The present embodiment described above shows an example of the present invention, and the air conditioner 10 does not limit the configuration of the air conditioner to which the present invention is applied. For example, although the ceiling cassette type air conditioner 10 is used as the air conditioner in the present embodiment, the present invention is not limited to this, and other embedded type air conditioners, as well as exposed type air conditioners such as wall hanging type air conditioners, etc. The present invention may be applied to. That is, by making the blow side of the fan casing accommodating the fan such as the cross flow fan 36 separable, the fan can be taken out and removed from the blow side of the fan casing, and the installation work can be performed very easily. ,
Maintainability is greatly improved.

Further, when the casing is integrally housed in the casing of the indoor unit, a part of the casing can be attached and detached as necessary to secure a sufficient working space for removing the parts such as the fan. be able to.

[0060]

As described above, according to the present invention, it is extremely easy to remove the fan accommodated on the outlet side of the fan casing by dividing the outlet side of the fan casing accommodating the fan and taking it out. I have to. Further, according to the present invention, when the casing is integrally housed, a part of the casing is also removed, so that the casing does not narrow the working space and the fan can be easily removed.

Further, according to the present invention, the connection between the drive means and the fan can be released by simply removing the outlet, so that only the fan can be taken out easily and the maintainability is remarkably improved. It has an excellent effect that it can be improved.
