Abstract

PROBLEM TO BE SOLVED: To reduce the breadthwise dimension of a unit body to miniaturize an indoor unit for an air-conditioner, by interposing a partition panel installed as a setting tool of a motor between one end face of the breadthwise direction of a heat exchanger and an electric parts box. SOLUTION: A partition panel 26 is formed as a unit in the first setting tool 22 of motor and interposed between a heat exchanger 7 and an electric parts box 31. Accordingly, auxiliary pipes 32 installed at the end face of the heat exchanger 7 are prevented from touching the electric parts box 31 owing to the partition panel 26 and hence, the condensed drain on the auxiliary pipes 32 is prevented from flowing along the electric parts box 31. Although the auxiliary pipes project from the end face of the heat exchanger with different lengths from one another, since the partition panel 26 is positioned between the heat exchanger 7 and the electric parts box 3, the distance therebetween can be sufficiently lessened. And since the partition panel 26 is bent, the deadspace under the auxiliary pipes 32 is reduced and hence, the unit body 1 can be miniaturized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner in which a heat exchanger and an electric parts box are arranged side by side in a widthwise direction in a unit body.

[0002]

2. Description of the Related Art Generally, an air conditioner used at home is divided into an indoor unit and an outdoor unit, and these units are connected to each other by a refrigerant pipe and electric wiring. In such an air conditioner, there is a particularly high demand for downsizing the indoor unit.

The indoor unit has a unit body,
A heat exchanger is arranged in the unit body along the width direction. An auxiliary pipe that connects the refrigerant pipe of the heat exchanger to the refrigerant pipe of the heat exchanger of the outdoor unit is located on one end surface in the width direction of the heat exchanger. In recent years, this auxiliary pipe has a large number of protrusions from the end surface of the heat exchanger due to the multi-passage due to the miniaturization of the heat exchanger, and the different protruding dimensions are used to connect the auxiliary pipes so that they do not overlap. ing. Further, electric component boxes are arranged at predetermined intervals on one end side in the width direction of the heat exchanger with the auxiliary pipe interposed therebetween.

A drain pan is provided below the heat exchanger in the unit body so as to receive the drain dropped from the heat exchanger and the auxiliary pipe. The width dimension of the drain pan is formed larger than the width dimension of the heat exchanger so that the drain dropped from the auxiliary pipe can be reliably received.

However, since the protruding size of the auxiliary pipe from the end face of the heat exchanger is not constant, the width of the drain pan is set to have a sufficient margin. Therefore, it has been unavoidable that the width dimension of the unit body increases due to the increase in the width dimension of the drain pan.

Further, when the auxiliary pipe protruding from the end face of the heat exchanger comes into contact with the electric parts box arranged on the side of the heat exchanger, the drainage condensed on the auxiliary pipe flows through the electric parts box. is there.

Therefore, conventionally, for safety, it has been performed to increase the distance between the heat exchanger and the electric component box more than necessary, which also causes the width dimension of the unit main body to increase. Was there.

Further, when the auxiliary pipe projects from the end face of the heat exchanger, drain drops from the auxiliary pipe, so that electric parts and the like cannot be arranged in the space below the auxiliary pipe. Since the space becomes a dead space, the unit itself may have become larger by that amount.

[0009]

As described above, in the conventional indoor unit, the width of the drain pan is unnecessarily increased because the auxiliary pipes provided on the end faces in the width direction of the heat exchanger have different protruding sizes. Since the size of the unit was increased or the electric component box was installed on the side of the heat exchanger with an unnecessary gap, the width of the unit body was sometimes increased.

The present invention has been made based on the above circumstances, and an object thereof is to provide an indoor unit for an air conditioner in which the width dimension of the unit main body can be reduced to achieve miniaturization. Especially.

However, by providing the partition body 26, even if the above interval is reduced, the auxiliary pipe 32
Since it comes into contact with the partition body 26 and does not come into contact with the electric component box 31, it is possible to make the interval sufficiently small. Since the space can be reduced, the width dimension of the unit body 1 can be reduced accordingly.

By bending the partition 26, the dead space S in the lower portion of the auxiliary pipe 32 can be reduced. If the dead space S can be reduced, the unit body 1 can be downsized accordingly.

Further, a holding portion 35 is provided on the inner surface of the partition 26 facing the end surface of the heat exchanger 7, and the auxiliary pipe 32 is held by the holding portion 35. Therefore, the auxiliary pipe 32 can be reliably positioned, so that not only the drain dropped from the auxiliary pipe 32 can be reliably collected, but also the stress applied to the auxiliary pipe 32 at the time of installation can be reduced.

Further, the projection 26 provided on the outer surface of the partition 26
The distance between the partition 26 and the electric component box 31 can be kept constant by b. That is, since the minimum necessary interval can be secured by bringing the protrusion 26b into contact with the side surface of the electric component box 31, no wasteful space is generated to secure the interval.

Further, the second holding the fan motor 13
The motor holder 23 is provided with a compound mark 45 to position the fan motor 13 in the circumferential direction.
It is possible to make the position of the lead wire lead-out portion 13c projectingly formed on the outer peripheral surface thereof constant. If the position of the lead wire lead-out portion 13c can be made constant, a space for the lead wire lead-out portion 13c can be secured in a predetermined place at a necessary minimum.
This can also save space.
