[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner which cools or heats air in a heat exchanger to harmonize the indoor air.

[0002]

2. Description of the Related Art In an air conditioner, a refrigerant circulates between an outdoor unit including a compressor, an outdoor heat exchanger and an outdoor unit fan, and an indoor unit including an indoor heat exchanger and an indoor unit fan. However, the refrigerant flowing through each heat exchanger is cooled or heated by repeating vaporization and condensation by heat exchange with the outside air or the indoor air.

The indoor unit in such an air conditioner includes a wall-mounted indoor unit installed on a wall, a ceiling-embedded indoor unit installed by being embedded in a ceiling in a room, and a floor-standing indoor unit. There is a unit. In particular,
The ceiling-embedded indoor unit is effective in providing a wide and clean indoor space because there are no protrusions into the room.

As an example of such an indoor unit, the internal structure of a ceiling-embedded indoor unit will be described with reference to FIG. FIG. 5 is an exploded perspective view partially showing the internal structure of an indoor unit of a conventional air conditioner. In addition,
Although the configuration shown in the figure is described upside down with respect to the actual installation direction, the contents described below will be described based on the figure.

In the figure, reference numeral 15 is a tangential fan (indoor unit fan), 16 is a fan motor, 17 is a bearing, 20 is a base, 21 is a fan fixing seat, and 22 is a base.
Is a motor fixing seat, and 23 is a motor cover (motor fixing member).

The base 20 is integrally molded with a material such as a resin and is formed as a component of a casing having an external shape of an air conditioner. In addition, this base 2
There is also a case where a cosmetic skin is further attached to the outside of 0.
The inner wall surface (the side shown in the figure) of the base 20 is divided into a ventilation space F for circulating the sucked air and a motor installation space M to which the fan motor 16 and the like are attached. The wall W2 is formed. Further, a wall portion W1 is formed on the end side of the base 20 with the ventilation space F interposed therebetween so as to face the partition wall W2.

A tangential fan 15 (hereinafter referred to as "indoor unit fan") is installed in a ventilation space F formed by a wall W1 and a partition wall W2, and one end of this indoor unit fan 15 is a wall part. It is attached to the fan fixing seat 21 formed on W1. A bearing 17 and a holding plate 18 are used to attach the fan fixing seat 21 and the indoor unit fan 15, and the indoor unit fan 15
Is rotatably supported at one end thereof.

Further, the other end of the indoor unit fan 15 located on the partition wall W2 side is rotatably supported by a fan motor 16 provided in a motor installation space M separated by the partition wall W2. The fan motor 16 is fitted into a motor fixing seat 22 that is integrally molded with the base 20, and the shaft 16a of the fan motor 16 has the shaft 16a.
By being inserted in 5, the indoor unit fan 15 is rotatably supported.

Next, the motor fixing seat 22 for fitting and fixing the fan motor 16 will be described in detail. A semi-arcuate recess H1 is formed in the motor fixing seat 22 in accordance with the shape of the fan motor 16, and two wall portions W22a and W22b are formed so as to surround the recess H1. Of these two wall portions W22a and W22b, one is a wall portion W22a that is flush with the partition wall W2, and above this, a vibration damping rubber 16b (vibration damping material) provided in the fan motor 16 described later is provided. A semi-circular cutout 22a for inserting is formed. Further, of the two wall portions W22a and W22b described above, the other is the wall portion W22b which is separated from the above-described wall portion W22a by a dimension corresponding to the dimension of the fan motor 16 in the thrust direction (excluding the shaft 16a), Similarly, a semi-circular cutout 22b into which the anti-vibration rubber 16b provided in the fan motor 16 is fitted is also formed here.

Then, these notches 22a, 22b
By fitting the anti-vibration rubbers 16b provided on both sides of the fan motor 16, respectively, the fan motor 16 is constrained and fixed by the motor fixing seat 22.

Thus, the wall portions W22a and W22 are
Since b is provided at a predetermined interval, the fan motor 16
Does not shift in the thrust direction, and the shaft 16a serving as an output shaft for transmitting power is reliably connected to the indoor unit fan 15.

Further, the fan motor 16 is attached to the motor fixing seat 2
A motor cover 23, which is superposed on the motor fixing seat 22, is attached in order to ensure a close contact with the motor fixing seat 22. this is,
The indoor unit is mounted in order to prevent the fan motor 16 from falling off from the motor fixing seat 22 due to a wall-mounted type, a ceiling-embedded type, or the like.

The motor cover 23 is formed in an arc shape according to the external shape of the fan motor 16, and has a plurality of holes 2 at both ends for attaching to and detaching from the motor fixing seat 22.
3c is formed. These holes 23c are formed in accordance with the screw holes 22c of the motor fixing seat 22 described above. In addition, the motor fixing seat 2 is attached to the motor cover 23.
Similar to 2, the notch 23b for fitting the anti-vibration rubber 16b is formed. Further, the motor cover 23 is formed with a wall portion W23a that is flush with the partition wall W2. The vibration isolating rubber 16b is also formed on the wall portion W23a.
Is formed with a notch (not shown).

The indoor unit fan 15 is attached to the base 20 with the shaft 16a of the fan motor 16 inserted. This is because, after the indoor unit fan 15 and the fan motor 16 are housed, the arrangement interval between the indoor unit fan 15 and the fan motor 16 is such that the motor fixing seat 22 and the wall portion W.
This is because it is uniquely determined by the arrangement of the partition wall W2 from 1 and cannot be attached to the base 20 unless the shaft 16a is inserted.

The fan motor 16 fitted in the motor fixing seat 22 is then covered with a motor cover 23 and fixed with screws or the like. With such a configuration, one end of the indoor unit fan 15 on the fan motor 16 side is rotatably supported, and the other end on the opposite side is rotatably supported by the holding plate 18 and the bearing 17, as described above. The indoor unit fan 15 is rotationally driven according to the output of the fan motor 16.

An indoor heat exchanger (not shown) is attached to the base 20 after the indoor unit fan 15 is attached. This indoor heat exchanger is formed so as to cover the indoor unit fan 15 in accordance with the width dimension of the ventilation space F, and is screwed and attached to the wall portion W1 and the partition wall W2 forming the ventilation space F. .

As described above, the base 20 has a plurality of devices such as the indoor unit fan 15, the fan motor 16, and the indoor heat exchanger attached to the base 20 and is a component of the indoor unit. Assembled parts are mainly composed of.

[0018]

However, in the indoor unit of the air conditioner configured as described above, the indoor unit fan 15 needs to be attached to the base 20 with the shaft 16a of the fan motor 16 inserted. Therefore, these interfere with each other, and for example, it is difficult to remove the fan motor 16 and the indoor unit fan 15 individually during maintenance.

For example, the replacement work when only the fan motor 16 needs to be replaced because the fan motor 16 has failed will be described. When an operator removes the surface panel (not shown) facing the indoor side having the air intake port and the air outlet port, the indoor heat exchanger fixed to the base 20 and the motor cover 23 covering the fan motor 16 are removed. Exposed. Of course, the indoor unit fan 15 is latent on the back side of the indoor heat exchanger.

When the motor cover 23 screwed by an operator's hand is removed to remove the fan motor 16, the fan motor 16 fitted in the motor fixing seat 22 is exposed. At this time, since the fan motor 16 is fitted in the motor fixing seat 22 so as not to shift in the thrust direction, the shaft 16a of the fan motor 16 cannot be pulled out from the indoor unit fan 15. That is, the fan motor 16 cannot be removed from the motor fixing seat 22 only by removing the motor cover 23.

Therefore, the operator is obliged to pull out the fan motor 16 together with the indoor unit fan 15 from the base 20. However, in order to pull out the indoor unit fan 15, it is necessary to remove the indoor heat exchanger covering the indoor unit fan 15. Therefore, the operator first removes the indoor heat exchanger from the base 20.

By removing the indoor heat exchanger, the indoor unit fan 15 can be moved in the radial direction, whereby the fan motor 16 is removed from the motor fixing seat 22 together with the indoor unit fan 15. And shaft 1
6a is pulled out, and the fan motor 16 is removed from the base 20, that is, the indoor unit.

As described above, in order to remove the fan motor 16, it is necessary to remove the indoor unit fan 15 and also the indoor heat exchanger, which is a heavy burden on the operator at the time of maintenance such as a failure, and many It took time.

Particularly, in the case of a ceiling-embedded indoor unit,
Since the worker is to work near the ceiling, it is more difficult to remove the fan motor 16, the indoor unit fan 15, the indoor heat exchanger, and the like while facing upward, as compared with the wall-mounted indoor unit. Becomes More specifically, in order to remove the fan motor 16, the worker removes the motor cover 23 while suppressing the indoor heat exchanger and the refrigerant pipes connected to the indoor heat exchanger. Remove the fan motor 16 while supporting it. Then, the fan motor 16 to be replaced is replaced and returned to the original state. In this way, the weight of all the devices to be removed becomes a burden on the worker, and the problem of maintainability is further exposed in the ceiling-embedded indoor unit.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an indoor unit of an air conditioner in which the maintainability of each device provided inside the indoor unit is improved.

By providing a fitting portion for fitting the fan motor in the motor fixing member, the fan motor is attached to the motor fixing member and they are easily integrated. As a result, when the fan motor moves to the gap portion, the motor fixing member moves together with the fan motor if the motor fixing member is in the state of being removed from the motor fixing seat. Then, when the motor fixing member is removed from the motor fixing seat, the fan motor is also removed from the motor fixing seat together with the motor fixing member.

According to a fifth aspect of the present invention, in the indoor unit of the air conditioner according to the fourth aspect, the fitting portion of the motor fixing member is provided with a protective member for absorbing vibrations provided in the fan motor. The feature is that the vibration material is fitted.

That is, the fan motor is fitted and fixed in the motor fixing member via the vibration-proof material provided in itself, and vibrations from the fan motor are prevented from being largely transmitted to the motor fixing member. It will be absorbed by the swing material. In many cases, the vibration damping material is generally made of a flexible material, and in this case, the vibration damping material can flexibly cope with the fitting of the fan motor and the motor fixing member without any margin. . Thereby, the work at the time of fitting is facilitated, and the adhesion is maintained high even after fitting.

According to a sixth aspect of the present invention, in the indoor unit of the air conditioner according to any one of the third to fifth aspects, the motor fixing member has at least the fitting portion in plan view. The feature is that it is divided into two parts.

Since the motor fixing member is divided, the fan motor is constrained by each part. Further, since the motor fixing member is divided at the fitting portion, the fan motor is not forced to fit into the fitting portion, and the fan motor and the motor fixing member can be more properly attached.

The indoor heat exchanger 6 shown in FIG. 1 is located below the indoor unit fan 15 and is constructed by combining two indoor heat exchangers 6a and 6b. The indoor heat exchanger 6 is attached to the base 30 at both ends in the longitudinal direction.

Next, the internal structure of the indoor unit will be described with reference to FIG. In addition, although the drawings (FIGS. 2 to 4) shown below are described upside down with respect to the actual installation direction, the contents described below will be described based on the drawings. . In the figure, reference numeral 30 is a base, 32 is a motor fixing seat, and 33 is a motor cover (motor fixing member).

Base 30 provided in the indoor unit
Is integrally molded with a material such as resin, and an inner wall surface (the side shown in the drawing) is formed with an arc-shaped wall surface or an inclined wall surface. The shape of such a wall surface is formed in order to allow the sucked air to flow smoothly,
It constitutes the ventilation space F. The ventilation space F functions as a ventilation passage by installing the indoor unit fan 15, the indoor heat exchanger 6 (see FIG. 1), etc. in the base 30.

The ventilation space F described above is provided on the base 30.
And a motor installation space M for mounting the fan motor 16 and the like
A partition wall W2 that is divided into and is formed. Further, a wall portion W1 located on the end side of the base 30 is formed so as to face the partition wall W2 with the ventilation space F interposed therebetween.

The above-mentioned indoor unit fan 15 is provided in the ventilation space F located between the wall W1 and the partition wall W2, and one end of this indoor unit fan 15 has the wall W1.
It is attached to the fan fixing seat 31 formed in. The bearing 17 and the restraining plate 18 are used for attachment to the fan fixing seat 31, and one end of the indoor unit fan 15 is rotatably supported by these.

The other end of the indoor unit fan 15 located on the partition wall W2 side has a motor installation space M separated by the partition wall W2.
It is supported by the fan motor 16 installed in the. The fan motor 16 is fitted into a motor fixing seat 32 that is integrally molded with the base 30, and the shaft 16 a of the fan motor 16 is inserted into the indoor unit fan 15 to rotatably support the indoor unit fan 15. To be done.

Next, the structure of the motor fixing seat 32 and the motor cover 33 for fitting and fixing the fan motor 16 will be described. The motor fixing seat 32 is integrally molded with the base 30, and a semi-arcuate recess H formed at that time is formed.
Equipped with 2. Further, both ends 32 of the motor fixing seat 32
Four screw holes 32c are formed in d and are provided for screwing a screw used when attaching a motor cover 33 described later.

Further, a wall portion W32a forming the same plane as the partition wall W2 is formed between the ventilation space F provided with the indoor unit fan 15 and the recess H2. This wall W32a
Is formed to have a half height of the fan motor 16 according to the shape of the recess H2, and the fan motor 1 is formed on the upper portion thereof.
The cutout 32a is formed in accordance with the shape of the anti-vibration rubber 16b provided in FIG.

The motor cover 33 is divided into two parts, one of which is an upper motor cover 34 formed in a semi-circular shape so as to cover the half surface of the fan motor 16.
The other is a side motor cover 35 that covers one side surface of the fan motor 16 (a side surface that does not include the shaft 16a).
The side motor cover 35 is mounted on the end side of the upper motor cover 34 with a screw 34d, and the mounting angle is a right angle.

The upper motor cover 34 is provided with a wall portion W34a which is flush with the partition wall W2 when it is attached to the motor fixing seat 32. The lower portion of the wall portion W34a conforms to the shape of the vibration-proof rubber 16b of the fan motor 16. A notch (not shown) that has been removed is formed. As described above, the wall portion W32a of the motor fixing seat 32 and the wall portion W34a provided on the upper motor cover 34 overlap with each other so that they are flush with the partition wall W2 and the ventilation space F and the motor installation space. It is shielded from M. Further, a notch 34a is formed on the wall surface of the upper motor cover 34 on the side where the side motor cover 35 is attached, the notch 34a being removed in accordance with the shape of the vibration isolation rubber 16b of the fan motor 16.

The side motor cover 35 has a flat plate shape,
A notch 35a is formed in a portion combined with the upper motor cover 34 so as to be removed in conformity with the shape of the anti-vibration rubber 16b included in the fan motor 16. Thus, each of the notches 34a, 35a described above is
The upper motor cover 34 and the side motor cover 35 are combined to form a circular hole having substantially the same size as the anti-vibration rubber 16b.
6 functions as a fitting portion 36 when the motor cover 33 is attached to the motor cover 33. Therefore, by fitting the anti-vibration rubber 16b so as to be sandwiched in the fitting portion 36, the fan motor 16 and the motor cover 33 can be easily integrated.

Further, the attachment / detachment structure of the fan motor 16 and the structure of the motor fixing seat 32 will be described in detail with reference to FIG. 3 which is a cross section of the motor fixing seat 32 and the motor cover 33. The conventional motor fixing seat 22 sandwiches and restrains both sides of the fan motor 16 so that the fan motor 16 does not move in the thrust direction (see FIG. 5). The motor fixing seat 32 shown in this embodiment is the same as the conventional motor fixing seat 22.
Unlike the structure of the above, the recess H2 and the ventilation space F2
The wall portion W32a which is separated from the above is a portion indicated by a length dimension L including a portion where the motor cover 33 is combined. That is, in the motor fixing seat 32,
The structure is not provided with a wall or the like that holds the fan motor 16 on the indoor unit fan 15 side and restrains it.

As shown in FIGS. 3 (a) and 3 (b), the width of the recess H2 into which the fan motor 16 is actually fitted is equal to the length dimension of the fan motor 16 in the thrust direction (excluding the shaft 16a). It has no structure for restraining the fan motor 16 at its end. As a result, the motor cover 33 is screwed to the motor fixing seat 3
2 is not fixed, the fan motor 16
Can move to the right side of the drawing together with the motor cover 33 (see FIG. 3B). This movable space on the motor fixing seat 32 forms the gap portion G (see FIG. 3A) according to the present invention.

As shown in FIG. 3B, the fan motor 1
When 6 moves in the thrust direction, the shaft 16a of the fan motor 16 inserted into the indoor unit fan 15 is pulled out, and the connection state between the fan motor 16 and the indoor unit fan 15 is released. Due to the structure of the motor cover 33, the fan motor 16 is removed from the motor fixing seat 32 without being interfered by the indoor unit fan 15 while being covered with the motor cover 33.

As described above, since the motor fixing seat 32 restrains the fan motor 16 in the thrust direction only by the wall portion W32a, the fan motor 16 is movable only in the direction away from the indoor unit fan 15, and is not separated. The motor cover 33 mainly serves to hold down the fan motor 16 on the indoor unit fan 15 side.

When the fan motor 16 is moved,
The motor cover 33 can have a function of temporarily holding the fan motor 16 (see FIG. 2). More specifically, when the motor cover 33 is moved in the thrust direction of the fan motor 16, the screw holes 32 that overlapped each other
c and the hole 34c again coincide with each other while gradually shifting. At this time, the screw motor 32 is simply screwed into the screw hole 32c from the overlapped hole 34c, so that the shaft 16a of the fan motor 16 is pulled out from the indoor unit fan 15. Retained. By temporarily holding the fan motor 16 on the base 30 side, the burden on the operator when only the indoor unit fan 15 is replaced is reduced, and the indoor unit fan 15 and the indoor heat exchange are performed. The function of removing the device 6 is particularly effective.

According to the indoor unit configured as described above, the fan motor 16 can be moved away from the indoor unit fan 15 at the same time as the motor cover 33 is removed, and the shaft 16a can be moved to the indoor unit. By being pulled out from the fan 15, the indoor unit fan 15
The fan motor 16 can be easily removed from the base 30 without interfering with the. This eliminates the need to remove the indoor heat exchanger 6 and the indoor unit fan 15 when only the fan motor 16 is removed, and the maintainability of the indoor unit can be greatly improved.

The fan motor 1 is attached to the motor cover 33.
Since 6 is attached and configured, the number of parts when removing the fan motor 16 is reduced, and the work is simplified and the work time is shortened. Also,
The close contact between the motor cover 33 and the fan motor 16 is enhanced, and the fan motor 16 can be more reliably fixed to the base 30 side.

Further, since the motor cover 33 is separable by the fitting portion 36, the fan motor 16 is prevented from being forcibly fitted into the motor cover 33 and damage to the motor cover 33 or the fan motor 16 is prevented. Thus, the fan motor 16 can be easily and appropriately attached to the motor cover 33.

As a modified example of this embodiment, the following configuration may be adopted. FIG. 4 is a diagram illustrating a mounting state of the fan motor 16 showing a modified example of the present embodiment, and FIG. 4A is a motor fixing seat 32 ′ and a motor cover showing a state in which the fan motor 16 is fixed. 33 'is a cross-sectional view, and (b) is a cross-sectional view of the motor fixing seat 32' and the motor cover 33 'showing the fan motor 16 removed.

In the figure, reference numeral 32 'is a motor fixing seat having a recess H2', 33 'is a motor cover formed as one component, and 37 is a detachable rib. Note that the other components are denoted by the same reference numerals and the description thereof is omitted.

The width of the recess H2 'into which the fan motor 16 is actually fitted is formed to be longer than the length dimension of the fan motor 16 in the thrust direction (excluding the shaft 16a), and the marginal space is the gap G. It is functioning. Further, on the recess H2 ′ in the gap G, a detachable rib 37 that is screwed is provided. The attachment / detachment rib 37 is formed in a semicircular plate shape according to the shape of the recess H2 ′, and is detachably attached to the motor fixing seat 32 ′ by screwing a screw.

Unlike the structure of the motor cover 33 described above, the motor cover 33 'is composed of one component, and the wall surface formed in the vertical direction on the paper surface has a vibration-proof rubber 16b for the fan motor 16. The stepped portion S formed in conformity with the shape of is provided.

The fan motor 16 is restrained on one side by the wall portion W32a of the motor fixing seat 32 'and the wall portion W34a of the motor cover 33', and on the other side by the motor cover 33 including the detachable rib 37 and the stepped portion S. By being suppressed by the wall surface of the ', it is restrained so as not to shift in the thrust direction so as to be separated from the indoor unit fan 15.

When removing the fan motor 16, the screwed motor cover 33 'is removed.
Further, by removing the attachment / detachment rib 37, the fan motor 16 moves above the motor fixing seat 32 ′ to the indoor unit fan 15
It is possible to move in a direction away from. As a result, the shaft 16a of the fan motor 16 does not interfere with the indoor unit fan 15, so the indoor unit fan 15 and the indoor heat exchanger 6
The fan motor 16 can be removed without removing (see FIG. 2).

Even if the attaching / detaching rib 37 is not provided,
Since the fan motor 16 is accurately fixed by the motor cover 33 ', the fan rib 16 may not have the attaching / detaching rib 37 in particular.

With this structure, the fan motor 16 can be relatively easily removed while the fan motor is accurately fixed by the attachment / detachment rib 37.

The indoor unit of the air conditioner of the present invention described above has the following effects. According to the first aspect of the present invention, the motor fixing seat into which the fan motor is fitted is provided with the gap portion that allows the fan motor to be separated from the indoor unit fan. Therefore, by moving the fan motor to the gap portion, the fan is moved. The connection between the motor and the indoor unit fan can be released. Therefore, the indoor unit fan and the fan motor can be changed to a state where they do not interfere with each other, and the maintainability of the indoor unit can be improved.

According to the second aspect of the present invention, since the detachable detachable ribs for holding the fan motor so as not to separate from the indoor unit fan are provided in the gap, it is appropriate if the detachable ribs are provided. The fan motor can be restrained, and when the fan motor is removed, the connection between the fan motor and the indoor unit fan can be released to improve the maintainability of each.

According to the third aspect of the present invention, since the motor fixing member that covers the fan motor and can be attached and detached is provided on the motor fixing seat, the movable fan motor is connected to the indoor unit fan. The state can be guided more reliably.

According to the fourth aspect of the present invention, since the fitting portion into which the fan motor is fitted is formed in the motor fixing member, the close contact between the fan motor and the motor fixing member is enhanced, and the fan motor is further improved. Can be securely fixed to the base. Further, since the fan motor and the motor fixing member are simply integrated, the number of parts can be reduced during work such as removal, and the efficiency of maintenance work can be improved.

According to the fifth aspect of the present invention, since the vibration isolator included in the fan motor is fitted in the fitting portion, vibrations of the fan motor are less likely to be transmitted to the motor fixing member.
Improves the durability of surrounding parts and equipment. Further, when the vibration-proof material is made of a relatively flexible material, the vibration-proof material can be easily fitted into the fitting portion, and the adhesion at the time of fitting is improved. At the same time, it is possible to prevent the fan motor and the motor fixing member from being damaged when fitting into the fitting portion.

According to the sixth aspect of the present invention, since the motor fixing member is divided so as to divide the fitting portion in plan view into two parts, the fan motor can be properly covered with the motor fixing member in each part. Further, the work of fixing the fan motor while covering it with the motor fixing member can be facilitated. Therefore, the fan motor is not forcibly fitted into the motor fixing member, and damage to the fan motor and the motor fixing member can be avoided.
