  • the air cleaner is mounted by directly securing the same to an end plate of the indoor heat exchanger with screws or by inserting the same into a heat exchange pipe constituting the indoor heat exchanger, as disclosed in Japanese Patent Laid-Open No. 3-59327.
  • the air cleaner is secured by screw fixing to the end plate of the indoor heat exchanger or by insertion into the heat exchange pipe.
  • the indoor heat exchanger is joined to a rear plate with screws or engaged to an engaging portions provided for the rear plate so as to be secured.
  • the indoor heat exchanger is usually disposed such that its upper portion is inclined rearwards, that is, the upper portion is inclined toward the rear plate.
  • the air cleaner is joined to the front surface of the upper portion of the heat exchanger.
  • various means such as the engagement and screw fixing, it is preferable that screw fixing is employed to firmly secure the air cleaner.
  • a most usual structure is arranged such that an end of the air cleaner is secured to the end plate of the heat exchanger with screws.

  • a heat exchanger having all of the features of claim 1. Since the present invention is structured such that the securing means secures both of the heat exchanger and the air cleaner, the number of elements can be reduced. Moreover, appropriate intervals can be maintained among the heat exchanger, the air cleaner and the rear plate. Therefore, the assembling operation can be facilitated and the assembling accuracy can be improved.
  • an embodiment of the present invention is structured such that the fixing screws are inserted in the same direction when the air cleaner is joined to the front surface of the upper portion of the indoor heat exchanger having the upper portion which is inclined rearwards, the workability can be improved.

  • the air cleaner 12 having the above-mentioned structure forwards projects over the front heat exchanger section 5a, the width of the air cleaner 12 being the same as that of the front heat exchanger section 5a.
  • FIGS. 1A and 1B show a structure for joining the air cleaner 12 and the indoor heat exchanger 5 to the rear plate 4 by dint of the securing means K.
  • the securing means K is constituted by a securing plate 21 which is a metal and plate-like member and which is formed by bending, for example, a steel plate; and a plurality of fixing screws 22a to 22c which are fixing members.
  • the air cleaner 12 and the indoor heat exchanger 5 are integrally connected and secured to the securing plate 21. Moreover, the indoor heat exchanger 5 and the air cleaner 12 are joined and secured to the rear plate 4 through the securing plate 21.
  • the securing plate 21 is disposed above the indoor heat exchanger 5. That is, the securing plate 21 is disposed from the upper portion of the front surface of the front heat exchanger section 5a, which constitutes the indoor heat exchanger 5, to the upper portion of the back side of the sub-heat-exchanger section 5c through the top end of the rear heat exchanger section 5b.
  • the securing plate 21 is bent to be formed along end plates T disposed at the two ends of each of the heat exchanger sections 5a to 5c.
  • the end plate T of the front heat exchanger section 5a and the securing plate 21 are joined and secured to each other by the fixing screw 22a.
  • the fixing screw 22a is inserted from a diagonally upward portion.
  • the rear plate 4 has an upward portion 23 inclined diagonally.
  • An end 21a of the bent portion of the securing plate 21 which is placed on the end plate T on the back side of the sub-heat-exchanger section 5c is bent so that the end 21a of the bent portion is placed on the upper surface of the upward portion 23.
  • the end 21a of the bent portion of the securing plate 21 and the rear plate 4 are joined and secured to each other by the fixing screw 22b.
  • the fixing screw 22b is inserted from a diagonally upward position, similarly to the fixing screw 22a.
  • the indoor heat exchanger 5 has the structure that the front heat exchanger section 5a and the rear heat exchanger section 5b form the inverted V-shape, a space S is necessarily formed on the back of the rear heat exchanger section 5b.
  • the space S can be used as a working space for inserting/removing the fixing screw 22b between the securing plate 21 and the upward portion 23.
  • an end of the securing plate 21 adjacent to the front heat exchanger section 5a is bent so as to be brought into contact with a joining flange 25 formed integrally with the air cleaner 12.
  • the fixing screw 22c is used to join and secure the joining flange 25 and the end 21b of the bent portion of the securing plate 21 to each other.
  • the joining flange 25 is stood erect in a substantially perpendicular direction.
  • the end 21b of the bent portion of the securing plate 21 arranged to be brought into contact with the joining flange 25 is bent perpendicularly. Therefore, the fixing screw 22c for joining and securing the joining flange 25 and the end 21b of the bent portion of the securing plate 21 is inserted in a substantially horizontal direction.
  • the air cleaner 12 and the indoor heat exchanger 5 are integrally connected to each other by the securing means K incorporating the securing plate 21 and the fixing screws 22a to 22c. Moreover, the air cleaner 12 and the indoor heat exchanger 5 are joined and secured to the rear plate 4 through the securing plate 21.
  • the lower portion of the air cleaner 12 is positioned in close contact with the end plate T of the front heat exchanger section 5a and joined and secured to the same by a fixing screw 22d. Since the front heat exchanger section 5a has the above-mentioned shape, the fixing screw 22d is inserted in a substantially horizontal direction. As a result, each fixing screw 22d for joining and securing the upper and lower portions of the air cleaner 12 are inserted horizontally.
  • claw portions 51 projecting over the case body 50 toward the front heat exchanger section 5a disposed on the rear of the case body 50 are integrally formed at another end of the air cleaner 12 in the lengthwise direction. That is, the claw portions 51 are formed at positions opposite to the direction into which the screws for securing the securing plate 21 are inserted.
  • Each of the claw portions 51 has somewhat elasticity so as to be interposed and secured when the claw portions 51 are pushed from a forward position into a position between the two vertical heat exchange pipes P.
  • Air introduced through the first suction opening 15a is introduced into the air cleaner 12. That is, air allowed to pass through the deodorizing filter 14 is deodorized by the deodorizing filter 14. On the other hand, fine and floating dust in air allowed to pass through the electric dust collector 13 are electrically charged in the electric charge portion so as to be captured and gathered. As a result, cleaned air is introduced into the front heat exchanger section 5a constituting the indoor heat exchanger 5 so that heat exchange is performed.
  • Air sucked through the second suction opening 15b is directly introduced into the front heat exchanger section 5a so that heat exchange is performed. Air sucked through the suction opening 3a is introduced into the sub-heat-exchanger section 5c and the rear heat exchanger section 5b so that heat exchange is performed.
  • Air subjected to heat exchange in the heat exchanger sections 5a to 5c is guided from the cross-flow fan 8 to the draft duct 9, and then allowed to pass through the blowout opening 10 so as to be blown out into the room which must be conditioned. Air subjected to heat exchange is circulated in the above-mentioned passage so as to be introduced into the air cleaner 12 and the indoor heat exchanger 5. Thus, air can be cleaned and conditioned as required.
  • the securing means K incorporating the securing plate 21 and the fixing screws 22a to 22c integrally connect and secure both of the indoor heat exchanger 5 and the air cleaner 12 to the rear plate 4, the number of required elements can be reduced. Moreover, adequate intervals among the indoor heat exchanger 5, the air cleaner 12 and the rear plate 4 can be maintained.
  • the securing plate 21 is the metal plate, satisfactory strength can be realized. If an iron plate is employed, the cost of the element can be reduced. Moreover, satisfactory durability and strength can be realized.
  • the securing plate 21 Since the securing plate 21 is disposed above the indoor heat exchanger 5, drain water generated in the indoor heat exchanger 5 does not reach the securing plate 21. Therefore, generation of rust on the securing plate 21 can be prevented.
  • the fixing screw 22c between the securing plate 21 and the air cleaner 12 is inserted in the substantially horizontal direction. Therefore, even if an upper working space is insufficiently small because the indoor unit is joined to the surface of a portion of a wall adjacent to the ceiling of a room which must be conditioned, removal of the air cleaner 12 from the main body 1 or joining of the same to the main body 1 can easily be performed when maintenance is performed.
  • Both of the upper portion and the lower portion of the air cleaner 12 are secured to the front heat exchanger section 5a with the fixing screws 22d.
  • the air cleaner 12 is secured with screws at two positions, that is the upper and lower positions. Therefore, the air cleaner 12 can firmly be joined and secured. Since the fixing screws 22c and 22d are inserted in the substantially horizontal direction, the operation for attaching/detaching the air cleaner 12 can easily be performed when maintenance is performed.
  • the other end of the air cleaner 12 is arranged such that the claw portions 51 are simply inserted into a position between the heat exchange pipes P of the front heat exchanger section 5a so as to be secured. Therefore, when the fixing screw 22d which secures the end of the air cleaner 12 is removed after which the case body 50 is pulled forwards, the claw portions 51 are removed from the heat exchange pipe P. Thus, complete removal of the air cleaner 12 can significantly easily be performed.
  • both of the fixing screw 22a between the end plate T of the front heat exchanger section 5a and the securing plate 21 and the fixing screw 22b between the upward portion 23 of the rear plate 4 and the securing plate 21 are inserted in the diagonally upward direction, that is, the same direction. Therefore, attachment/detachment of the securing plate 21 can easily be performed when maintenance is performed.
  • the indoor heat exchanger 5 is formed into the inverted V-shape and the space S between the rear heat exchanger section 5b and the rear plate 4 is used to secure the securing plate 21 and the upward portion 23 of the rear plate 4 with the screws. Therefore, a large working space can be maintained when maintenance or the like is performed. Thus, the space S can effectively be used.
  • An embodiment of the present invention has the following characteristics in addition to the securing means K.
  • an opening 30 for piping is formed at each of right and left ends of the front panel 20, the right and left ends being corners between the side surface and the bottom surface of the front panel 20.
  • a panel bushing 31 is received in the opening 30 for piping so that the opening 30 for piping is closed.
  • FIG. 6 shows a detailed structure of the panel bushing 31.
  • the panel bushing 31 is made of the same material as that of the front panel 20. Also the color and thickness of the panel bushing 31 are the same as those of the front panel 20.
  • the panel bushing 31 has an L-shape.
  • Slits 32 which can be knocked out if necessary, are provided for each surface.
  • a hooking claw 33 projects over the leading end of each surface.
  • guide members 34 are integrally formed on the two sides of the hooking claw 33.
  • Each of the hooking claws 33 and the guide members 34 are detachable with respect to the ends of the piping opening 30 of the front panel 20. Therefore, the panel bushing 31 can be removed from the front panel 20, if necessary.
  • sub-pipes and electric wires are drawn out from either of the right portion or the left portion of the main body 1.
  • either of the sub-pipe or the electric wire may be drawn out from either of the side portion and the other element may be drawn out from the other side portion.
  • the panel bushings 31 are provided for both of the right end and the left end of the front panel 20 such that removal is permitted if necessary.
  • the openings 30 for piping can be opened to permit either of the right-hand piping and wiring structure and the left-hand piping and wiring structure.
  • a structure for preventing looseness which is caused from a repulsion of the sub-pipe H in the indoor unit may be employed.
  • the rear plate 4 is joined to an anchoring plate 35 which is previously joined to the surface of a wall of a room which must be conditioned.
  • a space Sa is formed between the anchoring plate 35 and a rear portion of the lower portion of the rear plate 4.
  • the sub-pipe H extending from the indoor heat exchanger, a drain hose D extending from the front drain pan 6 or an electric wire (not shown) are accommodated in parallel with one another in the space Sa.
  • the outer surface of the sub-pipe H is cooled and thus the outer surface is easily frosted. Since low temperature drain water flows through the drain hose D, the outer surface of the drain hose D can easily be cooled and frosted.
  • a heat insulating member 36 arranged to be bonded to the outer surface of the rear plate 4 is interposed among the sub-pipe H, the drain hose D and the rear plate 4.
  • the sub-pipe H and the drain hose D are accommodated in the space Sa in the above-mentioned state, the sub-pipe H and the drain hose D are accommodated in an undesirably small space. Since the sub-pipe H is a metal pipe and the anchoring plate 35 is joined and secured to a surface W of a wall of a room which must be conditioned, repulsion of the sub-pipe H is concentrated to the lower portion of the rear plate 4. That is, the lower end of the rear plate 4 is separated from the anchoring plate 35 in the above-mentioned state. That is, looseness takes place.
  • the lower end of the anchoring plate 35 is forwards bent and as well as bent rearwards in a diagonal direction so that a support flange 37 is formed.
  • the lower end of the rear plate 4 is extended rearwards so that the space Sa for accommodating the sub-pipe H and the drain hose D is closed.
  • An end of the extended portion is bent so that a bent member 38 which is in close contact with the support flange 37 is formed.
  • the bent member 38 and the support flange 37 are connected and secured to each other by a fixing screw 22. Therefore, the fixing screw 22 firmly secures the lower end of the rear plate 4 to the lower end of the anchoring plate 35. Therefore, even if repulsion is generated from the sub-pipe H which is accommodated in the space Sa, looseness of the lower end of the rear plate 4 can be prevented.
  • the lower end of the front panel 20 is extended until the lower end is brought into contact with the surface W of the wall of the room to shield the fixing screw 22.
