Description

TECHNICAL FIELD 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 main body.

As an indoor unit of an air conditioner, there has been proposed an indoor unit in which side fan units are attached to both left and right side surfaces of the main body of the indoor unit (Patent Document 1). These left and right side fan units are for generating non-heat-exchanged airflows separately from the heat-exchanged airflows blown out from the indoor unit body. The airflow generated by this side fan unit is an airflow in which room air sucked from the intake port of the side fan unit is directly blown out from the outlet port by the sirocco fan built into 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 faces downward or forward, the direction of the airflow can be changed in the vertical direction. Also, if a left-right airflow direction plate is attached to the outlet, the direction of the airflow can be changed in the left-right direction.

Therefore, in this indoor unit, the heat-exchanged airflow blown out from the air outlet of the indoor unit main body can be controlled by the air flow blown out from the air outlet of the side fan unit. For example, during cooling operation, the cold airflow from the outlet of the indoor unit and the airflow from the outlets of the left and right side fan units can be mixed to prevent the cold air from hitting the human body directly. can. Also, during heating operation, the warm air currents blown out from the air outlets of the indoor unit main body are pushed out from above by the air currents blown out from the air outlets of the left and right side fan units, so that every corner of the room can be warmed.

Also, a motor 311 is attached to a body-side side surface portion 313b facing the indoor unit body 200 . A suction port 313c1 is formed in the side surface portion 313c that serves as an external surface. An air guide passage 313e is formed in a portion extending from the circumference of the sirocco fan 312 to the outlet 316 of the lower surface portion 313d. A left/right airflow direction plate 317 is incorporated in the air outlet 316 . 313f is the upper surface portion, and 313g is the rear surface portion.

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

The holder 315 includes a side portion 315a that covers a portion of the outside of the side portion 313c of the housing 313, a top portion 315b that covers the top portion 313f of the housing 313, a rear portion 315c that covers the rear portion 313g of the housing 313, and a housing. 313 has a lower surface portion 315d that covers a portion of the lower surface portion 313d of 313 excluding the outlet 313d1. The side surface portion 315a is formed in a U shape when viewed from the right side in FIG. 6 so that the second suction hole 314a of the protection plate 314 is exposed. A guide slot 315e is formed between the side surface portion 315a and the side surface portion 313c of the housing 313 to guide the insertion of the filter plate 320 and hold it. Further, the rear surface shape of the rear portion 315c, that is, the rear surface shape of the side fan unit 300R is formed into 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 inserted into the guide slot 315e of the side fan main body 310 and a front cover 322 as a decorative panel integrally formed on the front edge 321a of the filter portion 321. As shown in FIG. The front cover 322 is continuous from the front edge 321a of the filter section 321 so as to cover the front section 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-like filter sheet 323, which will be described later, are regularly arranged in a portion surrounded by an upper edge 321b, a rear edge 321c, and a lower edge 321d. The entire arrangement portion 321f is formed in a circular shape. The front cover 322 has a convex curved shape in which a central portion 322c protrudes forward (to the left in FIG. 6) from an upper portion 322a to a lower portion 322b so as to fit into the front portion 313a of the housing 313 of the side fan main body 310. is formed in Further, the right side surface 322d of the front cover 322 is formed with a recessed handle portion 322e.

As shown in FIG. 8, on the outer surface 313b3 of the body-side side surface portion 313b of the housing 313 of the side fan body 310 of the side fan unit 300R (that is, the side facing the side surface 221a of the right notch-shaped portion 221 of the indoor unit body 200). A first decorative portion 313b1 is formed from the front surface portion 313a side of the housing 313 to the upper surface 313f side. A second decorative portion 313b2 is formed from the rear surface 313g side of the housing 313 to the lower surface 313d side. In other words, the first decorative portion 313b1 and the second decorative portion 313b2 are formed in the right notch shape of the right side surface 220 of the indoor unit body 200 when the right side fan unit 300R is rotated from the first rotational position to the second rotational position. It is formed in an exposed portion that does not face the portion 221 . Further, the first decorative portion 313b1 and the second decorative portion 313b2 have a plurality of concentric concave grooves extending in the radial direction around the center of rotation of the housing 313, that is, the rotation axis P2 of the right side fan unit 300R, which will be described later. It is a ripple shape formed so as to line up.

Therefore, when the side fan unit 300R rotates from the first rotation position toward the second rotation position, the side surface of the side fan body 310 of the side fan unit 300R on the body side of the housing 313 of the side fan body 310 during the period from the start of the rotation to the end of the rotation. The first decorative portion 313b1 on 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 portion 250 of the indoor unit main body 200. Appearance is improved in comparison. In particular, since the first decorative portion 313b1 and the second decorative portion 313b2 are formed in a wavy shape along the rotation direction of the right side fan unit 300R, an image matching the rotation of the right side fan unit 300R is imagined. It will be easier and the appearance will be improved in this aspect as well.

Further, on the rear 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. Although it is possible to form a ripple shape on the entire surface of the body-side side surface portion 313b of the housing 313, this makes it difficult to remove the mold 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, mold removal is facilitated and molding defects do not occur.

FIG. 9 shows an enlarged view of a portion A surrounded by a dotted line in FIG. 313c2 is an upper horizontal guide slope formed on the side surface portion 313c of the housing 313. As shown in FIG. The upper horizontal guide slope 313c2 is arranged from the upper end portion 315a1 of the side surface portion 315a near the upper surface portion 315b of the holder 315 toward the front surface portion 313a of the housing 313 in FIG. It has a sloping surface. As a result, the 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 is widened, 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 has become easier. 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.

FIG. 10 shows an enlarged view of the portion B surrounded by the dotted line in FIG. A lower vertical guide slope 313c3 is formed on the side surface portion 313c of the housing 313. As shown in FIG. This lower vertical guide slope 313c3 is inclined downward in FIG. 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 is widened, and the lower end portion 321c2 of the filter portion 321b of the filter plate 320 is inserted from the vertical direction. has become easier. That is, the lower vertical guide slow path 13c3 guides the insertion of the lower end portion 321c2 of the rear edge 321c of the filter portion 321 from the vertical direction.

Here, the filter section 321 will be described in detail with reference to FIGS. 11 and 12. FIG. FIG. 11 is a diagram showing the shape of a peripheral portion 321f1 provided around the array portion 321f so as to form the outline 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 in the peripheral edge portion 321f1 of the array portion 321f is smaller than the opening area of the first suction holes 321e other than the peripheral edge portion 321f1 of the array portion 321f. The outline of the image is less noticeable and the appearance is improved.

More specifically, the first suction holes 321e1 other than the peripheral edge portion 321f1 of the array 321f have the maximum opening diameter of 6 mm, but the opening diameter is smaller than 6 mm at the inner side 321f11 of the peripheral edge portion 321f1, and is smaller than 6 mm at the outer side 321f12. The diameter of the opening becomes progressively smaller. That is, the opening area decreases in the order of the first suction holes 321e1, 321e2, 321e3, 321e4, and 321e5 shown in FIG. Thereby, a gradation is formed on the peripheral portion 321f1. Therefore, compared to the case where all the first suction holes 321e are formed with small holes having the same opening area, the peripheral edge portion 321f forming the outline of the array portion 321f is less conspicuous, and the appearance is improved.

In addition, a fixing pin hole 321g for fixing the filter sheet 323 at the time of resin molding is formed in the circumferential direction of the outermost first suction holes 321e5 or in the vicinity thereof. 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.

The filter plate 320 is molded of resin, and the filter portion 321 thereof is located between the upper mold 410 and the lower mold 420 as shown in FIG. Then, a mesh filter sheet 323 positioned by fixing pins 421 of the lower mold 420 is interposed, and resin is injected between the upper mold 410 and the lower mold 420 to form. Although one fixing pin 421 is shown in FIG. 12, a plurality of fixing pins are provided in the mold for stretching the filter sheet 323 . Therefore, the trace of the fixing pin 321 is exposed to the filter portion 321 as a through hole 321g.

Furthermore, the protective plate 314 covering 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. is covered by the peripheral portion 321f1 of the array portion 321f. For this reason, the screw B1 becomes less conspicuous, and the appearance is improved in this aspect as well.

The right side fan unit 300R is assembled by assembling the sirocco fan 311, the motor 312, the protection plate 314, the holder 315, and other necessary parts into the housing 313 of the side fan main body 310, and then attaching the filter as shown in FIG. With the rear edge 321c of the plate 320 leading, the filter portion 310 is inserted into the guide slot 315e of the holder 315 of the side fan body 310 until the front cover 322 of the filter plate 320 completely covers the front portion 313a of the side fan body 310. push in.

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

Thus, 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 main body 310. As shown in FIG. At this time, the entire filter plate 320 can be tilted toward the front surface portion 313a of the side fan main body 310 along the upper lateral guide slope 313c2.

Therefore, when inserting the filter portion 321 of the filter plate 320 into the guide slot 315e of the holder 315 of the side fan 310, it becomes easy to align the filter portion 321 of the filter plate 320 with respect to the guide slot 315e. The operation of inserting the portion 321 into the holder 315 is facilitated.

By inserting the filter plate 320 into the side fan main body 310 as described above, the filter portion 321 of the filter plate 320 is assembled in a state positioned in front of the protection plate 314 of the side fan main body 310 . As described above, the right side fan unit 300R is attached to the stepped portion 221 of the right side surface 220 of the indoor unit main body 200. As shown in FIG.

At this time, the front portion 313 a of the side fan main body 310 is covered with 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 hits the front end 315b1 of the upper surface portion 315b of the housing 313 of the side fan main body 310. As shown in FIG. Also, the rear end 322b1 of the lower portion 322b of the front cover 322 of the filter plate 320 hits the front end 315d1 of the lower surface portion 315d of the housing 313 of the side fan main body 310. As shown in FIG.

Therefore, the seam line D1 where the rear end 322a1 and the front end 315b1 meet is exposed on the top surface and side surface of the right side fan unit 300R, but not on the front surface, as shown in FIGS. Also, the line line D2 where the rear end 322b1 and the front end 315d1 meet is exposed on the bottom and side surfaces of the right side fan unit 300R, but not on the front surface, as shown in FIGS. Therefore, only the front cover 322 of the filter plate 320 appears on the same side of the right side fan unit 300R as the front surface 230 of the indoor unit 100, and the lines D1 and D2 do not appear, thereby improving the appearance.

However, since the line D2 is located on the lower surface of the side fan unit 300R, it can be seen when the indoor unit 100 is viewed from below. Since it is aligned with the line D3, there is no sense of incongruity.

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 moves toward the right side surface 220 of the indoor unit main body 200. rotates along the curved wall surface 221b of the right notched portion 221 of the . Therefore, the arc image 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 your finger on the recessed grip portion 322e formed on the right side surface 322d of the front cover 322 of the filter plate 320 and then forward ( 6), the filter plate 320 can be pulled out. As a result, only the filter plate 320 can be cleaned or replaced.

A sirocco fan rotation axis P1 that is the center of rotation of the sirocco fan 312 of the right side fan unit 300R, and a side fan that is the center of rotation of the right side fan unit 300R with respect to the right notched 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, the distance X1 from the front cover 322 of the filter plate 320 of the right side fan unit 300R, that is, from the front surface of the right side fan unit 300R to the sirocco fan rotation axis P1, and the side fan rotation from the same front surface. 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.

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

When the right side fan unit 300R is rotated from the first rotational position as shown in FIG. 13 to the second rotational position about the side fan rotation axis P2 as shown in FIG. , an upper corner portion 322a2 of the upper portion 322a of the front cover 322 of the filter plate 320 protrudes upward. However, compared to the case where the side fan rotation axis P2 is at the same position as the sirocco fan rotation axis P1, the upward protrusion distance L2 of the upper corner portion 322a2 from the upper surface 240 of the indoor unit main body 200 is smaller. Therefore, the appearance of the indoor unit 100 is improved by reducing the protrusion amount of the upper corner portion 322a2. In addition, when the indoor unit 100 is attached to the indoor wall surface 500, the indoor unit 200 can be brought closer to the ceiling 600 by reducing the projection amount of the corner portion 322a2. That is, since the distance L3 between the upper surfaces 240 of the indoor unit body 200 can be reduced, the degree of freedom of the mounting height of the indoor unit 100 on the wall surface 500 is increased.

Furthermore, since the sirocco fan rotation axis P1 is shifted toward the front surface portion 313a of the housing 313 from the side fan rotation axis P2, as shown in FIG. The distance L4 between P1 becomes larger than when the sirocco fan rotation axis P1 coincides with 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 horizontal direction in FIG. Air blow resistance can be reduced.
