Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner separated into an indoor unit and an outdoor unit, and more particularly to the internal structure of the indoor unit.

[0002]

2. Description of the Related Art An air conditioner equipped with a refrigerating cycle apparatus for cooling an air-conditioned room or switching to heating to perform an air-conditioning operation is generally composed of an indoor unit and an outdoor unit. ing. In the indoor unit,
The indoor heat exchanger and the blower are housed and arranged, and are attached to the wall surface of the air-conditioned room. In the outdoor unit, cycle components such as a compressor, an outdoor heat exchanger, a blower, and an expansion valve are housed and arranged, and naturally, they are arranged outside a house.

In such an air conditioner, since the compressor that easily emits operating noise is inside the outdoor unit, the person in the air-conditioned room is not affected by the noise. That is, quiet and comfortable air conditioning can be obtained.

However, the outdoor unit accommodating and arranging the compressor inevitably has an excessive weight and a large size.
It is extremely disadvantageous in the form of a house where it is difficult or difficult to secure an installation space outdoors.

For example, a structure in which an outdoor unit is hung at a high place of a veranda in a condominium or the like, and an installation space is substantially unnecessary is often used, but it occupies a space in the vicinity of a person's head and looks good. It's bad, and it's necessary to always use nerves in terms of risk prevention.

[0006]

SUMMARY OF THE INVENTION In order to avoid the excessive weight and the increase in size of such an outdoor unit,
The compressor housed in the outdoor unit was moved to the indoor unit, leading to the idea of eliminating the above-mentioned problem.

The problem here is the internal structure of the unit body that constitutes the indoor unit. That is, the indoor heat exchanger, the blower, and the compressor are newly housed in the unit body.

The compressor always radiates heat during the refrigeration cycle operation. When the compressor is housed in the unit main body, if this heat is mixed with heat exchange air during the cooling operation, it becomes an extra cooling load and power consumption is wasted.
The heat of the compressor must be cut off.

Specifically, it is necessary to accommodate the indoor heat exchanger and the blower in the same space, and to accommodate the compressor in a space different from this. Of course, each space part
Partitioned from each other.

In the conventional structure in which the compressor is not housed in the indoor unit, the inlet and outlet are formed on the front surface of the unit body, while the rear plate is provided on the rear surface.
This rear plate is bent along the back of the blower,
The lower end is connected to the outlet and constitutes a part of the fan casing.

On the other hand, it is conceivable to partition the compressor chamber with a partition plate separate from the rear plate in order to newly accommodate the compressor in the indoor unit. In this case, a gap is apt to appear between the rear plate and the partition plate, and heat and noise accompanying the operation of the compressor leak from this to the indoor heat exchanger side, and are guided to the room to be air-conditioned together with the heat exchange air. There is a decrease in efficiency and an increase in noise.

Further, in terms of the ventilation efficiency of the indoor blower, it is necessary to smoothly connect the partition plate of the compressor chamber to the fan casing, but since these are separate bodies, there is a problem with accuracy in smoothly connecting them. And
Poor assembly.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to suppress the leakage of noise accompanying the operation of the compressor on the assumption that the compressor is housed and arranged in the indoor unit. In addition, it is an object of the present invention to provide an air conditioner that has a structure that improves the air blowing efficiency of the air blower and that does not impair the assemblability.

[0014]

In order to satisfy the above object, an air conditioner of the present invention is an air conditioner comprising an indoor unit and an outdoor unit as claimed in claim 1, wherein the inside of the unit body of the indoor unit is And a partition plate integrally formed, which is divided into a blower chamber opened on the front side of the unit main body to accommodate and arrange the blower, and a compressor chamber opened on the rear side of the unit main body to accommodate and arrange the compressor. .

According to a second aspect of the present invention, the partition plate according to the first aspect is integrally provided with a reinforcing rib that also serves as a straightening plate, on the side of the fan chamber that faces both the fan chamber and the compressor chamber. Is characterized by.

According to a third aspect of the present invention, in the unit body according to the first aspect, an electric component chamber formed in one side portion of the partition plate for accommodating and arranging electric components and a refrigeration cycle formed in the other side portion of the partition plate. And a cycle parts chamber for accommodating and arranging parts.

[0017]

[Function] Since the partition plate is integrally formed so that the blower chamber is opened to the front side of the unit body and the compressor chamber is opened to the rear side of the unit body, the noise accompanying the operation of the compressor is transmitted to the blower chamber. It is possible to obtain a form that does not leak and that maintains good blowing characteristics.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the air conditioner of the present invention will be described below with reference to the drawings. As shown in FIG. 5A, the air conditioner is divided into an indoor unit 1 and an outdoor unit 2. The indoor unit 1 is attached and fixed to an upper portion of a wall surface of an air-conditioned room (not shown) by an appropriate means.
The outdoor unit 2 is installed and arranged on the outdoor ground (not shown).

These indoor unit 1 and outdoor unit 2
Are connected to each other by a communicating body 3 in which a refrigerant pipe and a power cord are bundled, and these constitute an air conditioner. As will be described later, by accommodating the compressor in the indoor unit 1, as compared with the conventional configuration in which the compressor is accommodated in the outdoor unit, the power supply control circuit and the room provided on the outdoor unit side. The signal line connected to the unit is unnecessary.

The outdoor unit 2 accommodates and arranges an outdoor heat exchanger (not shown) and refrigeration cycle parts such as an outdoor blower and an expansion valve. As shown in FIGS. 1 to 3, the unit main body 1A of the indoor unit 1 is composed of a front panel 4 and a rear plate main body 5, inside of which an indoor heat exchanger 6 and , Indoor blower 7
The compressor 8 and the like are housed and arranged.

A suction port 9 is formed in the front panel 4, and a suction grill 10 is provided therein. An outlet 11 is opened along the lower portion of the suction grill 10. A louver 12 is provided at the outlet 11.

The indoor heat exchanger 6 is arranged inside the front panel 4 so as to face the entire area of the suction grill 10. This indoor heat exchanger 6 has a large number of fins arranged side by side with a narrow gap, and penetrates the heat exchange pipes therethrough,
And meandering.

A drain tray 13 is provided with a gap from the lower end of the indoor heat exchanger 6. This drain saucer 13
Also forms a part of the blowout port 11, and serves as a nose of the blowout air passage 14 formed on the blowout side of the indoor blower 7.

The rear plate body 5 has a rectangular frame shape which is continuous with the rear opening of the front panel 4. A partition plate 15 is integrally installed over the upper and lower frame portions and in the portions excluding the left and right side portions.

That is, the partition plate 15 has a sectional shape that is substantially S-shaped in a side view. The left and right sides are closed by a closing plate 16 provided from the partition plate 15 to the rear edge of the frame part.

By such a partition plate 15, a lower space 17 having an opening facing the front surface is provided on the lower side of the partition plate, and an upper part having an opening facing the rear surface is provided on the upper side. The space portion 18 and the space portion 18 are formed.

The indoor blower 7 is arranged in the lower space 17 and is referred to as a blower room. This blower room 1
Since 7 also serves as a lower side portion of the blowout air passage 14, it is also a fan casing, and its end portion is connected to the blowout port 11.

In particular, as shown in FIG. 1, the indoor blower 7 is composed of a fan motor 7M and a cross flow fan 7F fitted to the rotating shaft of the fan motor. Only the cross flow fan 7F is located in the blower chamber 17.

The fan motor 7M is located at a position projecting outward from one end of the blower chamber 17, and has a cross flow fan 7F.
The bearing 18 that pivotally supports the free end of the fan is located at a position projecting outward from the other end of the blower chamber.

The cross-flow fan 7F is located on the back side of the indoor heat exchanger 6, and the axial length thereof is substantially the same as the width dimension of the indoor heat exchanger 6 and faces them. Therefore,
The width dimension of the blower chamber 17 which is the width dimension of the partition plate 15,
The cross-flow fan 7F and that of the indoor heat exchanger 6 substantially coincide with and face each other.

On the other hand, the compressor 8 is housed and arranged in the upper space portion 18 formed by the partition plate 15, and this space portion is called a compressor chamber. The compressor 8 is
This is a horizontal type so-called helical compressor whose axial direction is oriented horizontally. Here, both end portions are supported by the upper end portion of the partition plate 15 by a support tool (not shown).

A plurality of reinforcing ribs 19 ... Are present at predetermined intervals in the width direction on the blower chamber side of the partition plate 15 which is an intermediate portion of the partition plate 15 facing both the blower chamber 17 and the compressor chamber 18. And then be prepared as one.

That is, since the compressor 8 which is heavy in weight is supported on the upper end portion of the partition plate 15 via the support, the rigidity of the partition plate must be increased.
The partition plate 15 itself has a substantially S-shaped cross section to obtain a certain degree of rigidity, but in order to obtain a higher rigidity, the reinforcing ribs 19 ... Are integrally provided.

Since each of the reinforcing ribs 19 protrudes along the shape of the partition plate 15, the reinforcing ribs 19 have a rectifying function of the air blow obtained especially with the rotation of the cross flow fan 7F. That is, the reinforcing rib 19 also serves as the current plate.

There is a space formed by the closing plate 16 and the side plate of the rear plate body 15 at one side part (left side part in FIG. 1) of the partition plate 15 and this is formed in the electric part chamber 20.
Call. In the electric component room 20, the fan motor 7 is installed.
F, a drive circuit 21 for electrically controlling the drive of the compressor 8,
A main control circuit 22 that receives air conditioning conditions such as an instruction signal from a remote control panel such as a remote controller and a temperature signal detected by a temperature sensor and controls the operating state to an optimum operating state is housed.

The drive circuit 21 and the main control circuit 22 are electrically connected using the necessary code lines, and the compressor 8 and the drive circuit 21 are also electrically connected using the necessary code lines.

At the other side portion (right side portion in FIG. 1) of the partition plate 15, there is a space formed by the closing plate 16 and the side plate of the rear plate body 15, which is called a cycle parts chamber 23. A refrigeration cycle component 24 such as a four-way valve except the compressor 8, the indoor heat exchanger 6 and the outdoor heat exchanger is housed in the cycle component chamber 23.

The indoor unit 1 is constructed in this way. When the air conditioning operation is started, the compressor 8 radiates heat and operation noise occurs. This compressor 8 has a unit body 1
In A, the compressor chamber 18 which is the space on the back side of the partition plate 15
Is housed in.

The partition plate 15 is an integrally molded product and is provided from the upper end portion to the lower end portion of the rear plate body 5, and there is no room for generating a gap in the middle thereof. Therefore, heat and noise of the compressor 8 do not leak into the air-conditioned room through the front panel 4, an extra cooling load is not applied, and silent operation can be obtained.

The fan chamber 17 of the partition plate 15 also serves as a fan casing, so that particularly high assembly accuracy is not required and the air blowing efficiency of the fan 7 can be improved. Since the blower chamber 17 and the compressor chamber 18 are partitioned by the partition plate 15 which is an integrally molded product, it is not necessary to prepare a separate member.
Easy to assemble.

Since the partition plate 15 is provided with the reinforcing ribs 19 which also serve as the current plate, there is no problem in the supporting rigidity of the heavy compressor 8 and the heat exchange air can be smoothly blown to the air-conditioned room.

The compressor 8 can be arranged substantially in the center of the unit main body 1, so that the balance is improved and the installability is improved. Dew tends to adhere to the cycle components 24 housed in the cycle component chamber 23 during the refrigeration cycle operation. On the other hand, the electric components 21 and 22 arranged in the electric component chamber 20 are reluctant to intrude and attach dew (water) from the viewpoint of preventing electric leakage.

In the above-mentioned structure, the partition plate 1 includes the cycle component chamber 23 in which dew is easily generated and the electric component chamber 20 in which dew is disliked.
Since they are arranged on both sides of 5 and separated from each other by a large distance, it is possible to surely prevent the electric leakage of the electric parts 21 and 22.
The reliability can be improved.

The compressor 8 is of a horizontal type with its axial direction oriented horizontally, and is arranged in parallel in the upper space of the cross flow fan 7F via the partition plate 15 so that it is a dead space of the unit body 1A. The upper space of a certain cross-flow fan 7F can be effectively used, the height of the unit body 1A can be reduced, and the weight balance can be improved.

Further, since the compressor 8 and the cross flow fan 7F have the same axial direction, the vibration of the unit main body 1A is reduced as compared with the case where the compressor 8 and the cross flow fan 7F are arranged so as to have different axial directions.

Since the electric component chamber 20 is provided with the drive circuit 21 for electrically driving and controlling the compressor 8, these are arranged close to each other. The drive circuit 21 and the main control circuit 22 that controls the entire air conditioner are also arranged close to each other. Therefore, the mutual transmission / reception system can be simplified, and the design of the electric control system and the actual wiring work can be simplified as compared with the conventional system in which the compressor is housed in the outdoor unit.

In FIG. 5B, the compressor is attached to the outdoor unit 30.
Shows the air conditioner of the model (conventional) housed in. The width dimension W2, the height dimension H2, and the depth dimension S2 of the outdoor unit 30 are much larger than the width dimension W1, the height dimension H1, and the depth dimension S1 of the outdoor unit 2 of the present invention shown in FIG. .

In other words, the outdoor unit 30 of the conventional model
Compared with the above, the outdoor unit 2 of the present invention can be greatly downsized in the vertical and horizontal directions and the depth, the installation space can be reduced, the weight can be reduced, and the supporting structure can be simple.

Comparing the indoor unit 1 of the present invention with the indoor unit 40 of the conventional structure, the height dimension H3 and the width dimension W3 of the indoor unit 2 of the present invention are the height dimension H4 and the width of the indoor unit 40 of the conventional structure. It is almost equal to the dimension W4.

However, the depth dimension S3 of the indoor unit 1 of the present invention is unavoidably larger than the depth dimension S4 of the indoor unit 40 of the conventional structure because the compressor 8 is newly accommodated and arranged. However, this difference is minimal, and the projected feeling of the air-conditioned room (which is also a feeling of pressure on the person in the air-conditioned room) can be suppressed as much as possible.

After all, in the indoor unit 1 of the present invention, only the depth dimension is slightly increased as compared with the indoor unit 40 of the conventional structure, but this is unnoticeable at first glance and gives an unpleasant feeling. It is certain that it will not be reached.

In the above embodiment, the partition plate 15
Although the lower space formed by the above is the blower chamber 17 whose front surface is open and the upper space is the compressor chamber 18 whose rear surface is open, the present invention is not limited to this.

For example, the indoor unit shown in FIGS. 4A and 4B may be used. In this case, the indoor heat exchanger 50 is formed in an inverted V shape, the front heat exchanger 50a is inclined upside down, and the rear heat exchanger 50 is projected and inclined to the back side. Suction ports 9 and 9a are provided on the front surface side and the upper surface side of the unit main body 51 according to the form of the heat exchanger 50.

Since it is the indoor heat exchanger 50 as described above, a space for housing the compressor 8 cannot be secured on the upper side of the unit main body 51. Therefore, although the partition plate 52 here does not have an S-shape, it is possible to partition the space portion having the front opening and the space portion having the back opening, and the indoor blower 7 is accommodated in the space having the front opening. Blower room 53
However, a compressor chamber 54 accommodating the compressor 8 is obtained in the space of the rear opening. With such a configuration, the same operational effect as the above-described embodiment can be obtained.

In this embodiment, the electric component chamber 20 and the cycle component chamber 23 are shown left-right reversed from the above-described embodiment, but the actual operation and effect are the same. Since other configurations are the same, the same numbers are given here and a new description is omitted.

[0056]

As described above, the present invention provides claim 1.
In the above, since the inside of the unit main body of the indoor unit is divided into a blower room opening to the front side of the unit main body and a compressor room opening to the rear side of the unit main body by an integral partition plate, the operation of the compressor is accompanied. The effects of preventing heat radiation and noise leakage, avoiding an increase in cooling load, achieving quiet operation, improving air blowing efficiency, and avoiding deterioration of assemblability are achieved.

In the second aspect of the present invention, since the partition plate is integrally provided with a reinforcing rib that also functions as a straightening plate on the side of the fan chamber opposite to both the fan chamber and the compressor chamber, the rigidity of the partition plate is increased. Is obtained, the supporting strength of the compressor can be secured,
And the rectifying effect of heat exchange air is obtained.

According to a third aspect of the present invention, the compressor has a central portion of the unit main body, an electric component chamber for accommodating and disposing electric components on one side,
Since the cycle component chamber for accommodating and arranging the refrigeration cycle component is disposed on the other side, the arrangement balance is improved and the installability is improved. The cycle parts that generate dew and the electrical parts that hate dew are placed in the most distant part in the unit body, and accidents of the electrical parts caused by dew can be reliably prevented.
The reliability can be improved.
