  • the cross flow fan 83 is driven to rotate by a fan motor 85 disposed at the right-hand side of the indoor heat exchanger 82.
  • By rotating the cross flow fan 83 indoor air is sucked into the indoor heat exchanger 82 from its front side. After heat exchange is carried out in the indoor heat exchanger 82, conditioned air is blown into a room from a lower part of the indoor heat exchanger 82.
  • An auxiliary piping 86 extends from the right-hand side of the indoor heat exchanger 82 in Fig. 28 .
  • the auxiliary piping 86 is composed of a liquid pipe and a gas pipe forming a refrigerant circuit between them and an outdoor unit (not shown). After the auxiliary piping 86 is pulled out from the indoor heat exchanger 82, the auxiliary piping 86 is disposed at the right-hand side of the indoor heat exchanger 82. Then, the auxiliary piping 86 is covered with a heat insulation to form a connection pipe 88.
  • the connection pipe 88 is disposed at a rear part of the casing body 81 from the right-hand side thereof to the left-hand side thereof.
  • An electric/electronic parts case 90 for accommodating electric/electronic component parts such as a microcomputer, a power amplifier for driving the motor, and the like is disposed at the right-hand side of the auxiliary piping 86 in such a manner that the electric/electronic parts case 90 does not interfere with an air path.

That is, unlike the conventional art, there is no need for providing the indoor unit casing with a particular space for disposing the electric/electronic parts at the lateral sides of the indoor unit casing. Therefore it is possible to reduce the longitudinal dimension of the indoor unit and make the indoor unit compact.
  • the indoor unit of the present invention has a larger space for disposing a heat exchanger and a fan than the conventional indoor unit. Therefore, the indoor unit of the present invention has improved air-conditioning performance over the conventional indoor unit.

Further the electric/electronic parts unit is disposed in a region located between the indoor heat exchanger and the front panel, i.e., the electric/electronic parts unit is disposed in an air path. In this case, however, because the sectional area of the electric/electronic parts unit is small, it is possible to suppress the increase of the resistance to air. Further at cooling and warming operation times, it is possible to cool the electric/electronic parts unit with circulation air and improve the reliability of the electric/electronic parts.
  • the electric/electronic parts unit may be disposed in a region positioned at a rear side of an indoor unit.

  • the electric/electronic parts unit 14 is composed of a plurality of printed circuit boards, and the printed circuit boards are mounted on the same substrate and electrically connected to each other.
  • the electric/electronic parts unit 14 is constructed in this manner, from the viewpoint of making the electric/electronic parts unit 14 compact and facilitating handling thereof, it is preferable that the electric/electronic parts unit 14 is formed in the shape of a pillar as a whole.
  • the electric/electronic parts unit 14 may be composed of a plurality of units 14a, 14b, and 14c which are displaced from each other both in the longitudinal direction and in a direction (air flow direction) intersecting with the longitudinal direction. Constructing the electric/electronic parts unit 14 in this manner increases the degree of freedom in selecting the mounting positions of the units 14a, 14b, and 14c, whereby the units are disposed in appropriate positions according to the kind of an air conditioner.

  • the electric/electronic parts unit 14 is disposed in an air path 33 located between the front-side heat exchanger 2 and the front panel 7. In this case, because the sectional area of the electric/electronic parts unit 14 is also small as in the case of the above-described electric/electronic parts unit 14, it is possible to suppress the increase of the resistance to air flow.
  • the electric/electronic parts unit 14 is long and narrow and disposed symmetrically in its longitudinal direction. Thus if the electric/electronic parts unit 14 makes resistance to air flow at the inlet side, the resistance to air flow will not be unbalanced between the left-hand side and the right-hand side. Thus it is possible to prevent occurrence of a disadvantage such as generation of condensation on a rotor.
  • the indoor heat exchanger 4 inside the indoor unit casing 1 is constructed by combining the front-side heat exchanger 2 and the rear-side heat exchanger 3 with each other in the shape of an inverted letter "V" as in the above-mentioned case.

  • the electric/electronic parts unit 14 performs a function of sealing the junction portion of the front-side heat exchanger 2 and the rear-side heat exchanger 3, which dispenses with the use of a sealing material.
  • the manufacturing cost can be reduced.
  • the electric/electronic parts unit 14 By providing the electric/electronic parts unit 14 with two functions, a necessary space is reduced accordingly. This also makes it possible to make the indoor unit compact and improve the air-conditioning performance. Further in these cases, at cooling and warming times, the electric/electronic parts unit 14 can be cooled with the circulation air and the reliability of the electric/electronic parts can be improved.
  • the present invention can be implemented by separately providing a sealing member. In this case, too, it is possible to obtain the advantage that the indoor unit can be made compact and the air-conditioning performance can be improved.
  • the electric/electronic parts unit 14 is disposed in back of the rear-side heat exchanger 3 in the indoor unit casing 1. Because in the indoor unit casing 1, the electric/electronic parts unit 14 is disposed in the rear side region of the indoor unit which is a dead space, spaces inside the indoor unit casing 1 can be more effectively utilized. Consequently it is possible to make the indoor unit more compact or further improve the air-conditioning performance.
  • the electric/electronic parts unit 14 is disposed in a region behind the scroll portion 10 constructing a rear wall of an outlet passage. Because in the indoor unit casing 1, the electric/electronic parts unit 14 is disposed in the rear region behind the scroll portion 10, of the indoor unit, which is a dead space, the space inside the indoor unit casing 1 can be more effectively utilized. Consequently it is possible to make the indoor unit more compact or further improve the air-conditioning performance. In this case, the electric/electronic parts unit 14 is disposed outside the air circulation path in the indoor unit casing 1. Consequently it is possible to prevent the electric/electronic parts unit 14 from increasing a resistance to air flow directly. Therefore deterioration of the air-conditioning performance owing to the installation of the electric/electronic parts unit 14 is suppressed.

For example, utilizing a spare space extending inside the indoor unit casing 1 in its longitudinal direction, an electric/electronic parts unit 14 having an increased proportion of a dimension in the longitudinal direction may be disposed along the spare space. By thus doing, the electric/electronic parts unit 14 can be disposed in various spaces in sections as viewed in a direction perpendicular to the longitudinal direction of the indoor unit casing 1.
  • the indoor unit of the present invention has a larger space for disposing the heat exchanger 4 and the fan 9 than the conventional indoor unit. Therefore, the indoor unit of the present invention has improved air-conditioning performance over the conventional indoor unit. It is meant by the "increased proportion of a dimension in the longitudinal direction" that a dimension in the longitudinal direction is larger than dimensions in the other two directions orthogonal to the longitudinal direction. The value of the proportion does not matter. It is preferable that the proportion of the longitudinal dimension of the electric/electronic parts unit 14 is set larger than the proportion of the longitudinal dimension of the indoor unit casing 1.
  • the electric/electronic parts unit 14 in a region which adjoins the air outlet 11 and the air inlet 8, at a position above the air outlet 11 and between the drain pan 13 and the front panel 7 ( Fig. 4 ), in an air passage between the drain pan 13 and the front panel 7 ( Fig. 20 ), in the junction of the front-side heat exchanger 2 and the rear-side heat exchanger 3 ( Figs. 21 , 22 ), in a position at the rear side of the indoor unit casing 1 ( Fig. 23 ), or in a region behind the scroll portion 10 ( Fig. 24 ).
  • the electric/electronic parts unit 14 is composed of a plurality of separate constituent units 14a, 14b, and 14c, as shown in Figs. 16 and 17 , which are spaced from each other, it is preferable to increase proportions of the longitudinal dimensions of each constituent unit 14a, 14b, and 14c and also the proportion of the total longitudinal dimension of the entire layout of the constituent units.
  • a sealing member may be additionally provided. The advantage of reduction of the indoor unit size or improvement of the air-conditioning performance can be obtained even in this case.
  • the position above the air outlet 11 and between the drain pan 13 disposed below the heat exchanger 4 and the front panel 7 of the indoor unit casing 1 is a region which should be a dead space to prevent the outlet side and the inlet side from being short-circuited.
  • the indoor unit casing 1, the air outlet 11, the air inlet 8, and the electric/electronic parts unit 14 may have any configuration or shape. But by using the elongate indoor unit casing 1, forming the air outlet 11 and the air inlet 8 such that they extend laterally, and disposing the electric/electronic parts unit 14 along the air outlet 11, the effect of utilizing the space effectively can be displayed to a higher extent. Consequently the indoor unit can be made more compact or the air-conditioning performance can be improved further.
  • the electric/electronic parts unit 14 can be disposed such that the electric/electronic parts unit 14 performs an additional function of sealing the junction of the front-side heat exchanger 2 and the rear-side heat exchanger 3 ( Figs. 21 , 22 ).
  • the sealing material can be dispensed with and the manufacturing cost can be reduced.
  • the electric/electronic parts unit 14 has the two functions, a necessary space decreases accordingly.
  • the indoor unit can be made compact or the air-conditioning performance can be improved.
  • the electric/electronic parts unit 14 is disposed at an inner rear region of the indoor unit which is indeed a dead space within the indoor unit casing 1 ( Fig. 23 ), or at an outer rear position of the indoor unit casing 1 ( Fig. 24 ), the spaces inside the indoor unit casing 1 can be more effectively utilized.

  • the electric/electronic parts unit 14 is configured to have the shape of a thin plate, as shown in Figs. 25 and 26 , the electric/electronic parts unit 14 can be disposed at an inner rear position of the indoor unit casing 1 or at an outer rear position of the indoor unit casing 1.
  • the electric/electronic parts unit 14 can be shaped to be square, rectangular, rod-shaped, etc.
  • the electric/electronic parts unit 14 can be composed of a plurality of vertically elongate units, which are disposed separately from each other as shown in Fig. 26 .
  • the electric/electronic parts unit 14 is disposed either at a rear position, of the indoor unit, which is a dead space inside the indoor unit casing 1, or disposed at a rear position outside of the indoor unit casing 1, spaces inside the indoor unit casing 1 can be more effectively utilized. Consequently the indoor unit can be made more compact or the air-conditioning performance can be improved further.
  • the electric/electronic parts unit 14 is disposed at the rear side of the indoor unit casing 1, if the electric/electronic parts unit 14 is embedded in the scroll portion 10 composed of a foamed synthetic resinous material, as shown in Fig. 27 , the spaces inside the indoor unit casing 1 can be more effectively utilized without increasing the resistance to air flow inside the air flow path. Consequently the indoor unit can be made more compact or the air-conditioning performance can be improved further.
  • the indoor heat exchanger 4 inside the indoor unit casing 1 is disposed in almost all regions of the indoor unit casing 1 or of the air outlet 11. Constructing the indoor heat exchanger 4 in this manner makes it possible to increase the effective area of the heat exchanger 4 inside the indoor unit casing 1 and thereby improve the air-conditioning performance. If the performance of the air conditioner of the present invention is the same as that of the conventional air conditioner, the indoor unit casing 1 of the present invention can be made smaller than the conventional indoor unit casing.
  • the size of the indoor heat exchanger 4 does not refer to the size of only a portion thereof having plate fins, but the size of the indoor heat exchanger 4 including not only the plate fins but also a U-shaped heat transfer pipe disposed at one side thereof and a flow-dividing pipe or shunt disposed at the opposite side. It is preferable to mount the electric/electronic parts unit 14 removably. In this case, it is possible to improve assembling and maintenance performance.
  • the electric/electronic parts unit 14 is disposed, with its disposing direction orthogonal to each plate fin of the indoor heat exchanger 4. According to this construction, even if a circulation air flow is turbulent owing to the disposition of the electric/electronic parts unit 14, the direction of the turbulence is parallel to the plate fin-disposing direction. Thus, turbulence would not increase a circulation resistance when the air flow passes the plate fins. Consequently it is possible to prevent deterioration of the air-conditioning performance. Further the electric/electronic parts unit 14 is disposed orthogonally to the plate fins, the internal construction is symmetrical and thus the manufacturing cost can be reduced.
  • the longitudinal dimension of the fan mechanism including the fan 9 and the fan motor is almost equal to the lateral dimension of a fan mechanism of the indoor heat exchanger 4.
  • This construction allows the fan 9 and the indoor heat exchanger 4 to display their capabilities to the maximum.
  • the dimension of the indoor heat exchanger 4 in its longitudinal direction, or the lateral dimension of the indoor heat exchanger 4 means a total dimension including not only the dimension of the portion having the plate fins but also the dimensions of portions of the U-shaped heat transfer pipes disposed at both ends thereof.
  • the type of the indoor unit of the air conditioner is not limited to the wall-mounted type, but includes various types such as a floor-standing type, a ceiling-mounted built-in type, etc.
  • the longitudinal direction may be a left-to-right direction, a vertical direction or a horizontal direction, as viewed from a user.
  • the expression of "laterally elongate" used herein means w/h>1, where h is a vertical length and w is a lateral length.
