DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner provided with a ventilation fan unit.

[0002]

2. Description of the Related Art FIG. 4 is a schematic sectional view showing an indoor unit of a separation type air conditioner as a conventional example of the air conditioner. Inside the main body casing 41, there is provided an indoor heat exchanger 42 configured by connecting the front side heat exchanger 49 and the rear side heat exchanger 50 in an inverted V-shape. A cylindrical cross-flow fan 43 is arranged so as to be sandwiched between the inverted V-shapes of the indoor heat exchanger 42. Further, the back of the cross flow fan 43, the cross flow fan 4
Scroll part 40 for guiding the air flow generated by 3 to the room
Are formed.

FIG. 3 is a transparent front view of the indoor unit.
In the following, the right side shown in FIG.
Similarly, the left side shown in the figure is simply referred to as “left side”. As shown in the figure, the cross flow fan 43 is arranged along the lower part of the front side heat exchanger 49 so that the axial direction thereof extends left and right. A fan motor 45 is provided on the right side of the indoor heat exchanger 42. The cross flow fan 43 is driven to rotate by the fan motor 45. An auxiliary pipe 46 is drawn out from the right side of the indoor heat exchanger 42. The auxiliary pipe 46 includes a liquid pipe and a gas pipe which form a refrigerant circuit with an outdoor unit (not shown). The auxiliary pipe 46 is further heat-insulated to form a communication pipe 48. As shown in FIG. 4, the communication pipe 48
0 Body casing 4 through the piping processing space on the back side
1 are arranged from the right side to the left side. The communication pipe 48 is drawn out of the room through a through hole 39 provided on the left side surface of the main casing 41. In the space on the right side of the indoor heat exchanger 42, electrical components such as a microcomputer and a power amplifier for driving a motor are arranged, and a ventilation fan unit 44 is further provided. The ventilation fan unit 44 sucks indoor air and discharges the air outside the room. A ventilation duct 47 for that purpose is connected to the ventilation fan unit 44. This ventilation duct 47 is also provided from the right side to the left side of the main body casing 41 through the back side of the scroll portion 40 as shown in FIG. And the above ventilation duct 4
7 is drawn out of the room through the through hole 39.

[0004]

In the above-mentioned air conditioner, both the connecting pipe 48 and the ventilation duct 47 need to be drawn out from one side of the main body casing 41 to be disposed between the room and the outside. This facilitates the processing of the communication pipe 48 and the ventilation duct 47 having a hole, thereby improving the installation workability. However, when trying to pull out both the auxiliary pipe 46 and the ventilation duct 47 from one side of the main body casing 41 in this manner, in the indoor unit, the communication pipe 48 and the ventilation duct 47 are connected from right to left in the main body casing 41. Both must be arranged in parallel. Therefore, a large piping processing space must be secured in the main body casing 41,
This hinders downsizing of the indoor unit.
Also, as described above, a pipe processing space is secured on the back side of the scroll section 40, and the communication pipe 48 and the ventilation duct 4
In the case of a structure in which both of them are provided, the following problem occurs. That is, if the pipe processing space is small and the ventilation duct 47 and the communication pipe 48 cannot be completely accommodated therein, the indoor unit rises from the wall 38 after the installation of the indoor unit, and the installation workability is rather deteriorated. It will be.

On the other hand, when the through-hole 39 is provided on the right side of the main body casing 41 for convenience of installation, neither the ventilation duct 47 nor the communication pipe 48 needs to pass through the back side of the scroll portion 40. Therefore, the above problem does not occur. However, even in such a case, the fan motor 45, the ventilation fan unit 44, and the electrical components are unevenly located on the right side of the indoor heat exchanger 42. Therefore, there is a problem that the weight of the indoor unit is biased to the right and the balance is lost, which causes abnormal vibration.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to make it possible to reduce the size of equipment and to suppress occurrence of abnormal vibration. It is to provide a simple air conditioner.

In an air conditioner in which both the auxiliary pipe 6 and the ventilation duct 7 are drawn out of the main casing 1, the ventilation fan unit 4 is provided on the heat exchanger 2 on the side opposite to the auxiliary pipe drawing side. And

In the air conditioner of the first aspect, even if the auxiliary pipe 6 and the ventilation duct 7 are drawn out of the main body casing 1 from either side of the heat exchanger 2, one side of the heat exchanger 2 is provided. It is possible to arrange only one of the auxiliary pipe 6 and the ventilation duct 7 from the other side to the other side. In addition, the ventilation fan unit 4 and the auxiliary pipe 6 make it possible to achieve weight balance.

In the air conditioner according to a second aspect of the present invention, there is provided a heat exchanger 2 having an outlet side of an auxiliary pipe 6 disposed inside and outside the main body casing 1 on one side thereof. And a ventilation fan unit 4 configured to connect a ventilation duct 7 disposed through the inside and outside of the main body casing 1, and the auxiliary pipe 6 and the ventilation from either side of the heat exchanger 2. In the air conditioner in which both of the ducts 7 are drawn out of the main casing 1, the auxiliary pipe 6 is inserted into the pipe processing space behind the scroll.
And only one of the ventilation duct 7 is made to pass therethrough.

In the air conditioner of the second aspect, when the auxiliary pipe 6 and the ventilation duct 7 are drawn out of the main body casing 1 from either side of the heat exchanger 2, the heat exchanger 2

[0011]

Next, specific embodiments of the air conditioner of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a transparent front view showing an indoor unit of the air conditioner. Hereinafter, the right side shown in the figure is simply referred to as “right side”, and the left side similarly shown in the figure is simply referred to as “left side”. An indoor heat exchanger 2 is provided in the main casing 1, and the indoor heat exchanger 2 includes a front heat exchanger 9 and a rear heat exchanger (not shown) as in the above-described conventional example. Are connected in an inverted V-shape. And, as it is sandwiched between the inverted V-shaped of this indoor heat exchanger 2,
A cylindrical cross flow fan 3 is arranged. Further, a scroll portion (not shown) for guiding the airflow generated by the cross flow fan 3 into the room is formed at the back of the cross flow fan 3. The cross flow fan 3 extends along the lower part of the front heat exchanger 9,
It is arranged so that its axial direction extends left and right.
A fan motor 5 is provided on the right side of the indoor heat exchanger 2, and the fan motor 5 drives the cross flow fan 3 to rotate.

An auxiliary pipe 6 is drawn out of the indoor heat exchanger 2 from the right side thereof. The auxiliary pipe 6 includes a liquid pipe and a gas pipe which form a refrigerant circuit with an outdoor unit (not shown). A communication pipe 8 is formed by covering the auxiliary pipe 6 with heat. This connection pipe 8
Is disposed from the right side to the left side of the main body casing 1 through a piping processing space on the back side of the scroll portion. A through-hole 10 provided on the left side surface of the main body casing 1

On the other hand, on the left side of the indoor heat exchanger 2,
A ventilation fan unit 4 is provided. The ventilation fan unit 4 sucks room air and discharges the air outside the room. For that purpose, a ventilation duct 7 through which exhaust gas flows is connected to the ventilation fan unit 4. The exhaust duct 7 is drawn out of the room from the through hole 10.

In the indoor unit, the through hole 10 is provided on the left side surface of the main body casing 1, and the ventilation fan 4 is disposed on the left side of the indoor heat exchanger 2. Since the auxiliary pipe 6 is drawn out from the right side of the indoor heat exchanger 2, the communication pipe 8 is provided from the right side to the left side of the main casing 1. However, the exhaust duct 7 is drawn out of the main casing 1 from a through hole 10 provided in the vicinity of the ventilation fan 4 without being disposed on the left and right inside the main casing 1. Therefore, only the connecting pipe 8 is provided in the pipe processing space formed on the back side of the scroll portion. Therefore, even when the pipe processing space formed in the main body casing 1 is relatively small, the communication pipe 8 can be securely accommodated in this space, and a problem that the indoor unit rises from the wall after installation may occur. Absent. Therefore, downsizing of the device can be achieved while ensuring good installation workability. Further, since the ventilation fan 4 is disposed on the left side of the indoor heat exchanger 2, the weight can be balanced with the fan motor 5, the auxiliary pipe 6, and the electrical components disposed on the right side of the indoor heat exchanger 2. Therefore, it is possible to suppress the occurrence of abnormal vibration due to the weight balance collapse.

FIG. 2 shows a modification of the indoor unit. In this indoor unit, the through hole 10 is provided on the right side surface of the main body casing 1. Therefore, the ventilation duct 7 is provided from the left side to the right side of the main casing 1 through the piping processing space on the back side of the scroll portion. On the other hand, the communication pipe 8 is not disposed on the back side of the scroll portion, and is drawn out of the through hole 10 to the outside as it is. In this case, since only the ventilation duct 7 is provided in the piping processing space in the main body casing 1, even when this space is relatively small, the ventilation duct 7 can be securely accommodated, and the indoor unit rises from the wall after installation. There is no problem such as. Therefore, good installation workability is not impaired while miniaturizing the equipment. Further, the occurrence of abnormal vibration due to the weight balance collapse can be suppressed in the same manner as described above.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be variously modified and implemented within the scope of the present invention. In the above description, the present invention is applied to a wall-mounted indoor unit. However, according to the present invention, it is possible to prevent the ventilation duct and the communication pipe from being disposed in an overlapping manner in the main body casing, thereby making it possible to reduce the size of the device. Even when the present invention is applied to a machine, the excellent effect can be obtained.
In the above description, a ventilation fan unit for discharging indoor air to the outside is used, but a ventilation fan unit for exchanging indoor air with outdoor air may be used. Further, in the above embodiment (claim 1), the auxiliary pipe and the ventilation fan unit are arranged on both sides of the heat exchanger, but as shown in FIG.
Both the auxiliary pipe and the ventilation fan unit are arranged on one side of the heat exchanger, and only one of the auxiliary pipe and the ventilation duct passes through the pipe processing space, and the other is in an appropriate place such as above the heat exchanger. In this case as well, it is possible to prevent the ventilation duct and the connecting pipe from being disposed in an overlapping manner in the main body casing, whereby the size of the device can be reduced. The effect that can be obtained is obtained.

[0018]

According to the air conditioner of the first aspect of the present invention, regardless of which side of the main casing, the auxiliary pipe and the ventilation duct are drawn from one side of the heat exchanger to the other side. What is done can be either the auxiliary pipe or the ventilation duct only. Therefore, it is avoided that the auxiliary pipe and the ventilation duct are arranged overlapping in the main body casing, and it is possible to reduce the size of the device. In addition, since the weight is balanced between the auxiliary pipe and the ventilation fan unit, it is possible to suppress abnormal vibration caused by uneven distribution of weight.

In the air conditioner according to the second aspect of the present invention, regardless of which side of the main casing, the auxiliary pipe and the ventilation duct are drawn, the heat exchanger is provided from one side to the other side. Only the auxiliary pipe or the ventilation duct is provided, and therefore, it is avoided that the auxiliary pipe and the ventilation duct are disposed to be overlapped in the main body casing, and the size of the device can be reduced. .
