Description

  The present invention relates to an indoor unit of an air conditioner in which a side fan unit is attached to a side surface of an indoor unit body.

  As an indoor unit of an air conditioner, there has been proposed one in which side fan units are attached to both left and right side surfaces of the indoor unit body (Patent Document 1). These left and right side fan units are for generating an airflow that has not been heat-exchanged, in addition to the heat-exchanged airflow that is blown from the indoor unit body. The airflow generated by the side fan unit is the airflow in which the indoor air sucked from the suction port of the side fan unit is blown out from the air outlet as it is by the sirocco fan built in the side fan unit. At this time, if the position of the air outlet of the side fan unit is changed in the vertical direction so that the air outlet is directed downward or forward, the direction of the air flow can be changed in the vertical direction. Also, if a left / right airflow direction plate is attached to the air outlet, the direction of the air flow can be changed to the left / right direction.

  Therefore, in this indoor unit, it is possible to control the heat-exchanged airflow blown from the blowout port of the indoor unit body by the airflow blown from the blowout port of the side fan unit. For example, during cooling operation, it is possible to mix the cool airflow blown from the air outlet of the indoor unit body with the airflow blown from the air outlets of the left and right side fan units to prevent the cold air from directly hitting the human body. it can. Further, during the heating operation, the warm airflow blown out from the air outlet of the indoor unit main body is spread from above by the airflow blown out from the air outlets of the left and right side fan units, so that it can warm up every corner of the room.

  As described above, in the indoor unit 100 of this embodiment, the front covers 322 of the left side fan unit 300L and the right side fan unit 300R are separated from the front face 230 of the indoor unit main body 200 by the distance L1 in the direction of the back face 260 and the back face 260 of the back face 260. Since the recess is attached to the side, when the indoor unit 100 is viewed from the front, the width of the entire indoor unit 100 in the left-right direction looks small and the appearance is improved. Further, since the right lateral edge 321a of the front panel 231 projects laterally, a part of the lateral edge 321a can be used as a handle portion 231b for causing the front panel 231 to move forward. Since this handle portion 231b cannot be seen from the front surface, the appearance is improved also on this surface. The same applies to the left lateral edge of the front panel 231.

  Each of the left side fan unit 300L and the right side fan unit 300R has a side fan main body 310 and a filter plate 320 incorporated on the side surface thereof. Then, the indoor air is sucked through a large number of first suction holes 321e formed in the filter plate 320, which will be described later, and the sucked air is discharged into the room from the air outlet 316 of the lower surface 315d of the housing 313, which will be described later. Blow out. A left / right airflow direction plate 317 is attached to a part of the air outlet 316, and the left / right airflow direction plate 317 can deflect the blowing direction to the left / right direction.

  Next, as an example of the side fan unit 300R, an exploded perspective view thereof is shown in FIG. 6, and a sectional view thereof is shown in FIG. The side fan body 310 includes a housing 313 in which a motor 311 and a sirocco fan 312 that is rotated by the motor 311 are incorporated, and a protective plate that prevents a finger or the like from hitting the sirocco fan 312 when the filter plate 320 is removed. It has a holder 315 for incorporating the side fan main body 310.

  The housing 313 has a front surface 313a formed in a curved shape such that a central portion 313a3 projects forward (to the left in FIG. 6) from an upper portion 313a1 to a lower portion 313a2. Further, the motor 311 is attached to the main body side surface portion 313b facing the indoor unit main body 200. A suction port 313c1 is formed on a side surface portion 313c which is an external surface. Further, an air guide passage 313e is formed in a portion extending from the periphery of the sirocco fan 312 to the air outlet 316 of the lower surface portion 313d. Left and right wind direction plates 317 are incorporated in the air outlet 316. 313f is an upper surface portion and 313g is a rear surface portion.

  The protection plate 314 covers the suction port 313c1 of the side surface portion 313c of the housing 313 so that a finger is not inserted into the suction port 313c1. A large number of second suction holes 314a are formed in the protective plate 314, and the periphery of the protective plate 314 is attached to the side surface portion 313c of the housing 313 by a plurality of screws B1.

  The holder 315 includes a side surface portion 315a that covers a part of the outer side surface portion 313c of the housing 313, an upper surface portion 315b that covers the upper surface portion 313f of the housing 313, a rear surface portion 315c that covers a rear surface portion 313g of the housing 313, and a housing. The lower surface 315d has a lower surface 315d that covers a portion of the lower surface 313d except the air outlet 313d1. The side surface portion 315a is formed in a U shape in a right side view of FIG. 6 so that the second suction hole 314a of the protection plate 314 is exposed. A guide slot 315e for guiding and holding the insertion of the filter plate 320 is formed between the side surface portion 315a and the side surface portion 313c of the housing 313. Further, the back surface shape of the back surface portion 315c, that is, the back surface shape of the side fan unit 300R is formed in a convex curved shape corresponding to the concave curved shape of the wall surface 221b of the right cutout portion 221 of the indoor unit main body 200. There is.

  The filter plate 320 is formed of a filter portion 321 that is inserted into the guide slot 315e of the side fan body 310, and a front cover 322 as a decorative panel integrally molded with the front edge 321a of the filter portion 321. The front cover 322 is bent and continuous from the front edge 321a of the filter part 321 to cover the front part 313a of the housing 313 of the side fan main body 310 in FIG.

  In the filter portion 321, a large number of first suction holes 321e covered with a mesh filter sheet 323 described below are regularly arranged in a portion surrounded by an upper edge 321b, a rear edge 321c, and a lower edge 321d. The entire array portion 321f is formed in a circular shape. The front cover 322 has a convex curved shape in which a central portion 322c projects forward (to the left in FIG. 6) from an upper portion 322a to a lower portion 322b so as to fit into the front surface portion 313a of the housing 313 of the side fan main body 310. Is formed in. In addition, a concave handle 322e is formed on the right side surface 322d of the front cover 322.

  As shown in FIG. 8, on the outer surface 313b3 of the main body side surface portion 313b of the housing 313 of the side fan main body 310 of the side fan unit 300R (that is, on the side facing the side surface 221a of the right cutout portion 221 of the indoor unit main body 200). The first decorative portion 313b1 is formed from the side of the front surface 313a of the housing 313 to the side of the upper surface 313f. A second decorative portion 313b2 is formed from the rear surface 313g side of the housing 313 to the lower surface 313d side. That is, the first decorative portion 313b1 and the second decorative portion 313b2 have a right cutout shape of the right side surface 220 of the indoor unit main body 200 when the right side fan unit 300R rotates from the first rotating position to the second rotating position. It is formed in a portion that does not face the portion 221 and is exposed. In addition, the first decoration portion 313b1 and the second decoration portion 313b2 have a plurality of concentric concave grooves centering on a rotation center of the housing 313 described later, that is, a rotation axis P2 described later of the right side fan unit 300R in the radial direction. It has a ripple pattern formed in a line.

  Therefore, when the side fan unit 300R rotates from the first rotation position to the second rotation position, the main body side surface of the housing 313 of the side fan main body 310 of the side fan unit 300R is in the period from the start of rotation to the end of rotation. The first decorative portion 313b1 of the back surface 313b3 of the portion 313b is exposed from the upper surface 240 of the indoor unit main body 200, and the second decorative portion 313b2 is exposed from the lower surface 250 of the indoor unit main body 200. The appearance is improved in comparison. Particularly, since the first decoration portion 313b1 and the second decoration portion 313b2 are formed in a ripple shape along the rotation direction of the right side fan unit 300R, an image matching the rotation operation of the right side fan unit 300R is recalled. It becomes easier and the appearance is improved in this respect.

  Further, on the back surface 313b3 of the main body side surface portion 313b of the housing 313 of the side fan unit 300R, no ripple shape is formed except for the first decorative portion 313b1 and the second decorative portion 313b2. It is possible to form a ripple shape on the entire surface of the main body side surface portion 313b of the housing 313, but this makes it difficult to perform die cutting when forming the housing 313 by resin molding, resulting in defective molding. Cheap. However, when only the first decorative portion 313b1 and the second decorative portion 313b2 are provided as in the present embodiment, the die cutting becomes easy, and no defective molding occurs.

  FIG. 9 shows an enlarged view of a portion A surrounded by a dotted line in FIG. 313c2 is an upper lateral guide slope formed on the side surface portion 313c of the housing 313. The upper lateral guide slope 313c2 approaches the rear side surface plate 313b from the side of the upper end portion 315a1 of the side surface portion 315a close to the upper surface portion 315b of the holder 315 toward the front surface portion 313a of the housing 313 in FIG. It has a sloped surface. As a result, the lateral width of the insertion path of the filter portion 321 of the filter plate 320 into the upper introduction portion 315e1 of the guide slot 315e of the holder 315 becomes wider, and the upper end portion 321c1 of the filter portion 321b of the filter plate 320 can be inserted from the left-right direction. It's easy. That is, the upper lateral guide slope 313c2 guides the insertion of the upper end portion 321c1 of the rear edge 321c of the filter portion 321 from the left-right direction.

  An enlarged view of the portion B surrounded by the dotted line in FIG. 6 is shown in FIG. 313c3 is a lower vertical guide slope formed on the side surface portion 313c of the housing 313. The lower vertical guide slope 313c3 is inclined downward in FIG. 10 from the lower tip 315a2 of the side surface 315a close to the lower surface 315d of the holder 315 toward the front surface 313a of the housing 313. It is growing. As a result, the vertical width of the insertion path of the filter portion 321 of the filter plate 320 into the lower introduction portion 315e2 of the guide slot 315e of the holder 315 becomes wider, and the lower end portion 321c2 of the filter portion 321b of the filter plate 320 is vertically inserted. Has become easier. That is, the lower vertical guide slow path 13c3 guides insertion of the lower end portion 321c2 of the trailing edge 321c of the filter portion 321 from the vertical direction.

  Here, the filter unit 321 will be described in detail with reference to FIGS. 11 and 12. FIG. 11 is a diagram showing the shape of the peripheral edge portion 321f1 provided around the array portion 321f so as to form the contour of the array portion 321f in which a large number of first suction holes 321e are regularly arrayed. The opening area of the first suction holes 321e of the peripheral portion 321f1 of the array portion 321f is smaller than the opening area of the first suction holes 321e other than the peripheral portion 321f1 of the array portion 321f, and the peripheral portion 321f1, that is, the array portion 321f. The contours of the are less noticeable and the appearance is improved.

  More specifically, the opening diameter of the first suction holes 321e1 other than the peripheral edge portion 321f1 of the array 321f is 6 mm, which is the maximum, but the opening diameter is smaller than 6 mm on the inner side 321f11 of the peripheral edge portion 321f1, and on the outer side 321f12. The diameter of the opening is gradually decreasing. That is, the opening area becomes smaller in the order of the first suction holes 321e1, 321e2, 321e3, 321e4, 321e5 shown in FIG. 11, and the opening diameter of the outermost first suction hole 321e5 is, for example, about 2 mm. As a result, a gradation is formed on the peripheral portion 321f1. Therefore, as compared with the case where all the first suction holes 321e are formed of small holes having the same opening area, the peripheral edge portion 321f forming the contour of the array portion 321f becomes less conspicuous and the appearance is improved.

  In addition, a fixing pin extraction hole 321g for fixing the filter sheet 323 at the time of resin molding is formed in or around the outermost first suction holes 321e5 in the circumferential direction. The opening diameter of the vent hole 321g is, for example, about 1 mm, which is about the same as the opening diameter of the first suction hole 321e5 and becomes inconspicuous, so that the appearance is also improved in this aspect.

  The filter plate 320 is molded of resin, and the filter portion 321 of the filter plate 320 is between the upper mold 410 and the lower mold 420 as shown in FIG. 12, which is a cross-sectional view taken along line C1-C2 of FIG. Then, a mesh-shaped filter sheet 323 positioned by the fixing pins 421 of the lower mold 420 is interposed, and then resin is injected between the upper mold 410 and the lower mold 420 to form it. Although the number of fixing pins 421 is one in FIG. 12, a plurality of fixing pins 421 are provided in order to stretch the filter sheet 323 in the mold. Therefore, the traces of the fixing pin 321 are exposed as holes 321g in the filter portion 321.

  Further, the protective plate 314 that covers the suction port 313c1 of the housing 313 of the side fan main body 310 is attached to the housing 313 with a screw B1, and the screw B1 is the first suction hole 321e of the filter portion 321 of the filter plate 320. Is covered by the peripheral edge portion 321f1 of the array portion 321f. For this reason, the screw B1 becomes inconspicuous, and the appearance is also improved in this aspect.

  The right side fan unit 300R is assembled by assembling the sirocco fan 311, the motor 312, the protective plate 314, the holder 315, and other necessary parts in the housing 313 of the side fan main body 310, and then, as shown in FIG. Starting from the rear edge 321c of the plate 320, the filter part 310 is placed in the guide slot 315e of the holder 315 of the side fan body 310, and the front cover 322 of the filter plate 320 completely covers the front part 313a of the side fan body 310. Push in.

  At this time, when the lower edge 321d side of the rear edge 321c of the filter portion 321 of the filter plate 320 is inserted into the lower portion 315e2 of the guide slope 315e of the side fan body 310, the front cover 322 of the filter plate 320 is moved downward. By tilting, the lower end portion 321c2 of the trailing edge 321c can be placed on the lower vertical guide slope 313c3.

  In this way, the lower edge 321d of the rear edge 321c of the filter portion 321 of the filter plate 320 is placed on the lower vertical guide slope 313c3. Then, the upper end portion 321c1 of the rear edge 321c of the filter portion 321 of the filter plate 320 is inserted into the upper portion 315e1 of the guide slope 315e of the side fan body 310. At this time, the entire filter plate 320 can be tilted toward the front surface portion 313a of the side fan body 310 along the upper lateral guide slope 313c2.

  Therefore, when the filter portion 321 of the filter plate 320 is inserted into the guide slot 315e of the holder 315 of the side fan 310, the filter portion 321 of the filter plate 320 can be easily aligned with the guide slot 315e, and the filter of the filter plate 320 can be easily aligned. The operation of inserting the part 321 into the holder 315 becomes easy.

  By the above insertion work of the filter plate 320 into the side fan main body 310, the filter portion 321 of the filter plate 320 is incorporated in a state of being located in front of the protective plate 314 of the side fan main body 310. Then, as described above, the right side fan unit 300R is attached to the step portion 221 of the right side surface 220 of the indoor unit body 200.

  At this time, the front surface 313 a of the side fan body 310 is covered by the front cover of the filter plate 320. Then, the rear end 322a1 of the upper portion 322a of the front cover 322 of the filter plate 320 abuts on the front end 315b1 of the upper surface portion 315b of the housing 313 of the side fan main body 310. Further, the rear end 322b1 of the lower portion 322b of the front cover 322 of the filter plate 320 abuts the front end 315d1 of the lower surface portion 315d of the housing 313 of the side fan main body 310.

  Therefore, the line D1 of the seam where the rear end 322a1 and the front end 315b1 abut is exposed on the upper surface and side surfaces of the right side fan unit 300R but not on the front surface, as shown in FIGS. Further, the line line D2 of the joint where the rear end 322b1 and the front end 315d1 abut each other is also exposed on the lower surface or side surface of the right side fan unit 300R but not on the front surface, as shown in FIGS. Therefore, on the same side as the front surface 230 of the indoor unit 100 in the right side fan unit 300R, only the front cover 322 of the filter plate 320 appears and the lines D1 and D2 do not appear, so that the appearance is improved.

  However, since the line D2 is on the lower surface of the side fan unit 300R, it can be seen when the indoor unit 100 is looked up from below. However, the line D2 serves as a ridgeline of the boundary between the front surface 230 and the lower surface 250 of the indoor unit main body 200. Since it is lined up with the line D3, no discomfort occurs.

  Further, when the side fan unit 300R rotates between the first rotation position and the second rotation position described above, the curved back surface portion 315c of the holder 315 of the side fan unit 300R causes the right side surface 220 of the indoor unit body 200 to move. It rotates along the curved wall surface 221b of the right cutout portion 221. Therefore, the image of the arc of the side fan unit 300R can be maintained, and the appearance is improved.

  When removing the filter plate 320 from the side fan main body 310 of the right side fan unit 300R, hook a finger on the recessed hand portion 322e formed on the right side surface 322d of the front cover 322 of the filter plate 320, and then the front ( The filter plate 320 can be pulled out by pulling it to the left in FIG. As a result, only the filter plate 320 can be cleaned or replaced.

  The sirocco fan rotation axis P1 which is the center of rotation of the sirocco fan 312 of the right side fan unit 300R, and the side fan which is the center of rotation of the right side fan unit 300R with respect to the right cutout portion 221 of the right side surface 220 of the indoor unit body 200. It does not coincide with the rotation axis P2. That is, as shown in FIG. 13, from the front cover 322 of the filter plate 320 of the right side fan unit 300R, that is, the distance X1 from the front surface of the right side fan unit 300R to the sirocco fan rotation axis P1, and from the same front surface side fan rotation. The distance X2 to the axis P2 is set to X1 <X2, and the sirocco fan rotation axis P1 is closer to the front cover 222 than the side fan rotation axis P2.

  Further, from the upper surface portion 315b of the holder 315 of the housing 313 of the side fan main body 310, that is, the distance Y1 from the upper surface of the right side fan unit 300R to the sirocco fan rotation axis P1 and the same upper surface from the side fan rotation axis P2. Y2 is set to Y1 <Y2, and the side fan rotation axis P2 is farther from the upper surface portion 315b than the sirocco fan rotation axis P1.

  As shown in FIG. 13, when the right side fan unit 300R is in the first rotation position described above, and as shown in FIG. 14, when the right side fan unit 300R is rotated about the side fan rotation axis P2 in the second rotation position described above. The upper corner portion 322a2 of the upper portion 322a of the front cover 322 of the filter plate 320 projects upward. However, the protruding distance L2 from the upper surface 240 of the indoor unit main body 200 in the upward direction of the upper corner portion 322a2 becomes smaller than when the side fan rotation axis P2 is located at the same position as the sirocco fan rotation axis P1. Therefore, the amount of protrusion of the upper corner portion 322a2 is reduced, so that the appearance of the indoor unit 100 is improved. Further, since the protrusion amount of the corner portion 322a2 is small, the indoor unit 200 can be brought close to the ceiling 600 when the indoor unit 100 is attached to the wall surface 500 in the room. That is, since the distance L3 between the upper surfaces 240 of the indoor unit main bodies 200 can be reduced, the degree of freedom in mounting the indoor unit 100 on the wall surface 500 is increased.

  Further, since the sirocco fan rotation axis P1 is shifted in the direction of the front surface portion 313a of the housing 313 with respect to the side fan rotation axis P2, as shown in FIG. 7, the back surface portion 313g of the housing 313 and the sirocco fan rotation shaft are rotated. The distance L4 between P1 becomes large compared with the case where the sirocco fan rotation axis P1 corresponds to the side fan rotation axis P2. Therefore, since the air guide passage 313e arranged inside the rear surface portion 313g of the housing 313 can be enlarged in the left-right direction in FIG. 7, the cross-sectional area of the air guide passage 313e can be increased, and the sirocco fan 312 can have a larger cross-sectional area. Blower resistance can be reduced.
