These constituent parts are arranged inside a casing comprising a front surface grille assembly 10, a front surface panel 11, a bottom frame 12, and the like.
  • the bottom frame 12 is fixed to an indoor wall and the like by mounting it to a mounting plate 15 fixed to an indoor wall surface.
  • An upper inlet 10a having slits is provided in the upper surface of the front surface grille assembly 10, and a front surface inlet 11a is also provided at the top and sides of the front surface panel 11.
  • Air cleaning air filters 17 are arranged on the inside of these inlets 10a,11 a.
  • an outlet for blowing out the airflow generated by the fan rotor 3 is formed at the front bottom part of the front surface grille assembly 10.
  • the fan rotor 3 is arranged in a fan housing part 12a formed in the bottom frame 12, with one end being attached to the bottom frame 12 via a bearing 13, and the other end being coupled to the rotational shaft of a motor 14.
  • This motor 14 is fixed to the bottom frame 12 by a motor fixed member 16.
  • the heat exchanger 4 is provided so that it surrounds the front, upper, and rear upper parts of the fan rotor 3, and is also split into a front side heat exchanger 141 and a rear side heat exchanger 142, each having an effective length L.
  • a front side heat exchanger 141 and a rear side heat exchanger 142 each having an effective length L.
  • numerous heat radiating fins are attached to a heat transfer pipe bent a plurality of times at both the left and right ends, the air sucked in from the upper inlet 10a and the front surface inlet 11 a by the drive of the fan rotor 3 is made to pass through to the fan rotor 3 side, and heat is exchanged between the air and the refrigerant that passes through the inside of the heat transfer pipe.
  • the heat exchanger 4 is connected via the refrigerant piping to the refrigerant piping from the outdoor unit.
  • a drain pan assembly 18 that includes a front drain pan, a vane for adjusting the direction of the blown out air, and the like.
  • the effective length of a front side heat exchanger and a rear side heat exchanger of a heat exchanger may not necessarily be the same.
  • the indoor unit of the above pair type air conditioner as shown in FIG. 1 and FIG. 2 and the indoor unit employed by a multi-split type air conditioner that connects a plurality of indoor units in parallel to one outdoor unit were conventionally designed separately. Given this situation, attempts are recently being made to standardize parts between pair type indoor units and multi-split type indoor units. Although the specifications for the heat exchanger often differ between a pair type and a multi-split type, the standardization of the casing parts and the like is conceivable.
  • the indoor unit of a multi-split type air conditioner is often internally provided with a motor operated valve because the plurality of indoor units are separately started and stopped, and controlled.
  • This motor operated valve serves the role of adjusting the amount of refrigerant flowing in the heat exchanger of the indoor unit, and generates a relatively loud noise, such as when the refrigerant expands in the liquid-gas mixture state.
  • a noise source of the motor operated valve and the like which are parts inherent to the multi-split type indoor unit, is arranged inside a regular pair type casing
  • the refrigerant piping bank in the pair type indoor unit is arranged in the space on the side of the centrally disposed heat exchanger.
  • the abnormal noise will cease if it is a pair type indoor unit, although it is assumed that abnormal noise from the motor operated valve and the like will leak out into the room if it is a multi-split type indoor unit.
  • JP-A-09-280597 discloses to cover refrigerant circuit parts with a sound proofing plate fixed to a heat exchanger and a water pan.
  • An indoor unit of an air conditioner according to the invention comprises the features of claims 1.
  • the present invention herein is constituted so that the effective length of the rear side heat exchanger is less than the effective length of the front side heat exchanger, and a prescribed space is created on the backside of the indoor unit. Furthermore, refrigerant circuit parts, such as the motor operated valve and the distributor that generate relatively loud sounds when changing the flow of the refrigerant, are arranged in that space. Thus, because the refrigerant circuit parts that constitute noise sources herein are arranged in the space on the backside inside the indoor unit, the amount of sound leaking out to the front side of the indoor unit is reduced, thus suppressing discomfort to people in the room.
  • the indoor unit is constituted so that the effective length of the rear side heat exchanger is less than the effective length of the front side heat exchanger, then the length of the fan rotor is matched to the front side heat exchanger, whose effective length would normally be thought to be long. Consequently, the abovementioned space (space created by the difference in the effective lengths of the front side heat exchanger and the rear side heat exchanger) is contiguous to a part of the fan rotor. In this case, even if nothing is provided between that space and the fan rotor, there is a risk that air will flow from the abovementioned space directly into the fan rotor without passing through the heat exchanger.
  • the partition plates are arranged between the space, wherein the refrigerant circuit parts are arranged, and the fan rotor, the problem of air flowing into the fan rotor without passing by the indoor heat exchanger is suppressed.
  • the indoor unit of the air conditioner may be the indoor unit of an air conditioner comprising an outdoor unit and a plurality of indoor units.
  • the refrigerant circuit parts arranged in the space, created because the effective length of the rear side heat exchanger is less than the front side heat exchanger, includes at least a motor-operated valve.
  • the motor operated valve is provided for adjusting the amount of refrigerant flowing to the plurality of indoor units.
  • the motor operated valve which is usually built into the indoor unit of a multi-split type air conditioner, is arranged in the space on the backside inside the indoor unit, which easily confines noise.
  • the motor operated valve sometimes generates a relatively loud abnormal sound when adjusting the amount of refrigerant; however, because it is arranged herein in the abovementioned space, which tends not to leak sound out of the indoor unit, a loud abnormal sound is no longer heard by people in the room.
  • the indoor unit may further comprise a metal member that covers the space wherein the refrigerant circuit parts are arranged.
  • the space is further covered by a metal member. Accordingly, even in a case where a loud abnormal noise generated from the refrigerant circuit parts passes through the casing, which is usually made of resin, and leaks out of the indoor unit, the leakage of that abnormal noise out of the indoor unit can be suppressed by the noise insulating effect of the metal member.
  • the indoor unit may further comprise a drain pan that receives drain water falling from the heat exchanger. Further, the lower ends of the (partition plates) windbreaking members extend to the drain pan.
  • This drain pan is arranged below the lower end of the front side heat exchanger and below the lower end of the rear side heat exchanger, and receives the drain water; it is also widely used in conventional indoor units.
  • An indoor unit of an air conditioner according to one embodiment of the present invention is used in a multi-split type air conditioner, as shown in FIG. 3 .
  • a multi-split type air conditioner 91 a plurality of indoor units 93 - 96 are connected to one outdoor unit 92.
  • the outdoor unit 92 and the indoor units 93 - 96 are connected by connecting parts 99a - 99d comprising refrigerant piping and a transmission line.
  • Four indoor units 93 - 96 are respectively arranged in separate rooms in, for example, a home, a building, or a store.
  • FIG. 4 depicts a refrigerant circuit 190 of the multi-split type air conditioner 91.
  • the refrigerant circuit 190 comprises one outdoor unit 92, four indoor units 93 - 96 connected in parallel to the outdoor unit 92, and refrigerant piping.
  • the outdoor unit 92 comprises a compressor 20, a four-way switching valve 21, an outdoor heat exchanger 22, an accumulator 23, and the like.
  • a discharge pipe thermistor 24 is attached to the discharge side of the compressor 20 for detecting the discharge pipe temperature on the discharge side of the compressor 20.
  • the outdoor unit 92 is provided with an outside air thermistor 25 for detecting the outside air temperature, and an outdoor heat exchange thermistor 26 for detecting the temperature of the outdoor heat exchanger 22.
  • Each of the indoor units 93 - 96 has the same constitution. The following explains the indoor units 93 - 96 using the indoor unit 93 as an example.
  • the indoor unit 93 comprises an indoor heat exchanger 4a and a motor-operated valve (expansion valve) 33a mutually connected in series.
  • the motor-operated valve 33a is provided on the refrigerant exit side of the indoor heat exchanger 4a and adjusts the amount of refrigerant flowing to the indoor heat exchanger 4a.
  • the indoor unit 93 respectively comprises a room temperature thermistor 31 a for detecting the indoor temperature, and an indoor heat exchange thermistor 32a for detecting the temperature of the indoor heat exchanger 4a.
  • a liquid pipe thermistor 34a for detecting the liquid pipe temperature between the indoor heat exchanger 4a and the motor-operated valve 33a is provided in the piping between the indoor heat exchanger 4a and the motor-operated valve 33a.
  • a gas pipe thermistor 35a is provided on the gas pipe side (refrigerant entrance side) of the indoor heat exchanger 4a for detecting the refrigerant temperature passing therethrough internally.
  • the other indoor units 94, 95, 96 are likewise constituted the same as the indoor unit 93, and their indoor heat exchangers, motor operated valves, and various thermistors are assigned equivalent symbols in FIG. 4 .
  • the indoor units 93 - 96 used in the multi-split type air conditioner 91 have built-in motor-operated valves 33a - 33d.
  • the following explains the indoor unit used in the multi-split type air conditioner, using the indoor unit 93 as an example, and focusing on the arrangement of the parts.
  • the indoor heat exchanger 4a that partially covers the front, upper, and rear parts of a fan rotor 3 principally comprises a front side heat exchanger 41 and a rear side heat exchanger 42, as shown in FIG. 5 and FIG. 6 .
  • the rear side heat exchanger 42 has an effective length that is less than the front side heat exchanger 41, and an end part 42b on a motor 14 side thereof is positioned closer to the central portion in the latitudinal direction of the indoor unit 93 than an end part 41b of the front side heat exchanger 41 (refer to FIG. 5 ).
  • a relatively large space SP is ensured on the outer side of the rear side heat exchanger 42 (the side on the motor 14 side).
  • the width dimension of this space SP is substantially the same dimension as the difference in the effective lengths of the front side heat exchanger 41 and the rear side heat exchanger 42, and is 100 - 150 mm.
  • a structure is employed in the indoor unit 93 wherein an upper end 41 a of the front side heat exchanger 41 is slightly spaced apart from an upper end 42a of the rear side heat exchanger 42, and a connecting plate 43 extends therebetween.
  • This connecting plate 43 integrates the front side heat exchanger 41 and the rear side heat exchanger 42 as the indoor heat exchanger 4a, and serves the role of preventing the unfortunate passage of the air from above the indoor heat exchanger 4a to the fan rotor 3 below without passing through the front side heat exchanger 41, the rear side heat exchanger 42, and the like.
  • the motor-operated valve 33a in the indoor unit 93, the motor-operated valve 33a, refrigerant piping 133 that connects to the motor-operated valve 33a, and a distributor 39 that divides the flow of refrigerant exiting the motor-operated valve 33a to each of the heat transfer passageways of the indoor heat exchanger 4a, and the like, are arranged in the space SP created by the difference in the effective lengths of the front side heat exchanger 41 and the rear side heat exchanger 42. As shown in FIG. 5 , the motor-operated valve 33a is arranged laterally to improve maintainability.
  • the space SP is enclosed by a metal cover 50, a vertical partition plate 44, and a lateral partition plate 45.

  • This metal cover 50 is provided principally for the purpose of isolating noise.
  • the vertical partition plate 44 and the lateral partition plate 45 are plate-shaped members made of metal and provided to prevent the leakage of air that flows into the space SP out to the fan rotor side.
  • the vertical partition plate 44 is positioned above the fan rotor 3, and partitions the space surrounding the fan rotor 3 and the space SP wherein the motor-operated valve 33a and the like are arranged.
  • the lateral partition plate 45 is a substantially triangular member that extends perpendicularly frontward from the end part 42b on the space SP side of the rear side heat exchanger 42, and the sides abut orthogonally with the end part 42b of the rear side heat exchanger 42, the end part on the space SP side of the connecting plate 43, and the end part of the vertical partition plate 44.
  • a front drain pan 61 is arranged below the lower end of the front side heat exchanger 41, and a rear drain pan 62 is arranged below the lower end of the rear side heat exchanger 42, respectively.
  • These drain pans 61, 62 form a bottom frame and a drain pan assembly having a constitution the same as the conventional bottom frame 12 and drain pan assembly 18 in FIG. 2 , and serve the role of receiving the drain water that drips downward from the indoor heat exchanger 4a and the like.
  • a drain route 63 is formed below the portion where the abovementioned vertical partition plate 44, the lateral partition plate 45, and the end part 42b on the space SP side of the rear side heat exchanger 42, which surround the space SP, intersect so that the drain water from that portion does not drip down to the fan rotor 3.
  • This drain route 63 is structured so that a metal plate is bent at the intersecting portion of the vertical partition plate 44 and the lateral partition plate 45 (a part of the vertical partition plate 44, a part of the lateral partition plate 45, or separate members mounted to these partition plates 44, 45), and so that its cross-section is pocket-shaped.
