  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The following embodiments are specific examples of the present invention and do not limit the technical scope of the present invention.

<Configuration of air conditioning indoor unit 1>
FIG. 1 is a perspective view of an air-conditioning indoor unit during operation stop. FIG. 2 is a perspective view of the air conditioning indoor unit during operation. 1 and 2, the air conditioning indoor unit 1 is a wall-hanging type, and a casing 10, a side member 24, and a movable panel 31 are mounted on a main body 20 as members that form an outer shell.

(Casing 10)
FIG. 3 is a cross-sectional view of the air conditioning indoor unit. The casing 10 forms a substantially rectangular three-dimensional space by the front surface portion 101, the upper surface portion 102, and the lower surface portion 103, and the frame 11, the indoor heat exchanger 12, the fan 13, and the filter 21 are accommodated in the three-dimensional space. Yes. In addition, the upper surface portion 102 is provided with a suction port 18 (see FIGS. 1 and 2) composed of a plurality of slits. Furthermore, the blower outlet 19 (refer FIG. 2) is provided from the lower part of the front-surface part 101 to the front part of the lower surface part 103. FIG.

  The indoor heat exchanger 12 and the fan 13 are attached to the frame 11. The indoor heat exchanger 12 exchanges heat with the passing air. The fan 13 blows the air taken in from the suction port 18 against the indoor heat exchanger 12 and then blows it out to the air outlet 19. The air outlet 19 is provided with a horizontal flap (not shown) for guiding the air to be blown out. The horizontal flap can be driven by a motor 171 to change not only the air blowing direction but also open and close the air outlet 19 on the lower surface portion 103 side.

  A filter 21 is disposed between the front surface portion 101 and the upper surface portion 102 of the casing 10 and the indoor heat exchanger 12. The filter 21 removes dust contained in the air flowing toward the indoor heat exchanger 12.

(Side member 24)
FIG. 4 is a perspective view of the side member immediately before being attached to the casing. In FIG. 4, the side member 24 is attached so as to cover the side of the casing 10, and bears the appearance of the casing 10 in a side view. Furthermore, the side member 24 has a laminated structure, and a first layer portion 241 that places importance on design is disposed on the outside, and a second layer portion 242 that supports the first layer portion 241 is disposed on the inside. ing. The first layer portion 241 is made of aluminum alloy, and the second layer portion 242 is made of ABS resin. The material of the first layer portion 241 is not limited to the aluminum alloy, and may be other metals such as stainless steel. In the present embodiment, since the aluminum alloy is light and has corrosion resistance and is suitable for long-term use, it is employed as the material of the first layer portion 241.

  The side member 24 is not perpendicular to the installation surface of the main body 20, and in particular, the second layer portion 242 has a curved shape having a substantially S-shaped cross section in the horizontal direction and projects outward from the front end. A front curved surface 242a that curves inward, and a rear curved surface (not shown) that curves so as to enter inside from the end of the front curved surface 242a toward the rear end.

  The first layer portion 241 is not attached to the entire surface of the second layer portion 242 but is attached in a range from the rear end of the second layer portion 242 to the maximum protruding portion of the front curved surface 242a. Note that the rear end of the second layer portion 242 is an end on the side close to the installation surface of the main body 20, and the opposite end is the front end.

(Mounting structure of casing 10 and side member 24)
Further, a screwing portion 242b is provided in the vicinity of the front end of the second layer portion 242, and a through-hole through which the screw 90 passes in the depth direction of the main body 20 is formed in the screwing portion 242b. Further, a claw portion 242 c is provided at the rear end of the second layer portion 242.

  On the other hand, a mounting portion 10 d is provided in front of the side end portion of the casing 10 at a position corresponding to the screwing portion 242 b of the side member 24. A screw hole into which the screw 90 is screwed in the depth direction of the main body 20 is formed in the mounting portion 10d. Furthermore, a hole 10c is provided behind the side end portion of the casing 10 so that the claw 242c of the second layer portion 242 is hooked.

  When the side surface member 24 rotates with the contact point between the claw portion 242c and the hole portion 10c as a fulcrum, the side member 24 stops at a position where the through hole of the screwing portion 242b and the screw hole of the mounting portion 10d on the casing 10 side meet. With this mounting structure, the operator can naturally position and fix the side member 24 to the casing 10 by simply rotating the claw portion 242c of the side member 24 until it hits the casing 10 by using it as a hinge. Since the screwing portion 242b of the side member 24 is screwed to the attachment portion 10d of the casing 10 in the depth direction of the main body 20, the positional deviation in the front-rear direction is naturally eliminated, and the side member 24 and the casing 10 are eliminated. The boundary between and becomes beautiful.

  Conversely, when the operator removes the side member 24 from the casing 10, the operator removes the screw 90 and then rotates the claw 242 c of the side member 24 outward by using the claw 242 c of the side member 24 as a hinge. Just pull out from 10c.

  Thus, since the side member 24 is attached to the casing 10 by a detachable attachment structure, for example, when the hole for extracting the pipe is not necessary due to the transfer of the air conditioning indoor unit, it is the same as before the hole is made. The side member 24 can be replaced. As a result, a state in which a hole remains in the corner portion of the casing 10 as in the conventional case or a state in which a trace of a treatment for eliminating the hole remains is avoided, and the design is not deteriorated.

(Movable panel 31)
1 and 2, the movable panel 31 creates a unique design by a front part 31a having a flat shape and side parts 31b continuously formed rearward from both ends of the front part 31a. In addition, the front part 31a and the side part 31b are integrally formed. The front part 31 a covers the entire front part 101 of the casing 10, and the side part 31 b covers the front half of the side member 24.

  As shown in FIG. 1, when the air conditioning indoor unit 1 is not in operation, the front portion 31 a of the movable panel 31 bears the front appearance of the air conditioning indoor unit 1. Further, since the side surface portion 31 b of the movable panel 31 covers the front half of the front curved surface 242 a of the side surface member 24, the side surface appearance is borne by the side surface portion 31 b of the movable panel 31 and the first layer portion 241 of the side surface member 24. That is, the outline of the air conditioner indoor unit 1 in the operation stop state includes the front part 31 a of the movable panel 31, the side part 31 b of the movable panel 31, the first layer part 241 of the side member 24, and the upper surface part 102 of the casing 10. The lower surface portion 103 of the casing 10 is configured.

<Features>
(1)
As described above, when the side member 24 rotates with the contact point between the claw portion 242c and the hole portion 10c as a fulcrum, the through hole of the screwing portion 242b and the screw hole of the mounting portion 10d on the casing 10 side are aligned. Since the structure stops at the position, the side member 24 is detachable from the casing 10. Therefore, when the hole for piping drawing processed previously by the relocation of the air conditioning indoor unit or the like becomes unnecessary, it can be replaced with the side member 24 equivalent to that before the hole is made.

(2)
Since the installation operator can screw the screwing portion 242b of the side member 24 toward the depth direction of the main body 20 with respect to the mounting portion 10d of the casing 10, the position in the front-rear direction is naturally determined, and the side surface The boundary between the member 24 and the casing 10 becomes clean.

<Other embodiments>
In the said embodiment, since the side member 24 is a 2 layer structure of the metal 1st layer part 241 and the resin 2nd layer part 242, the appeal power to a user's aesthetics by the 1st layer part 241 is Get higher. However, it is highly likely for the installation worker that it is difficult to perform a drilling operation when a through hole for pulling out a pipe is formed in the side member 24. Therefore, the applicant has proposed that the first member having the through hole 24a through which the pipe passes and the second member not having the through hole 24a are aligned as the form of the side member 24.

  FIG. 5 is a perspective view of the first form of the side member, and FIG. 6 is a perspective view of the second form of the side member. Since the installation worker can prepare both the first and second side members 24 in advance when installing the air conditioning indoor unit, the side surface of the first embodiment can be used when pulling out the piping from the side. When the member 24 is used and it is not necessary to pull out the pipe from the side, the side member 24 of the second form can be used. By doing so, the design of the side surface is not impaired. Further, the operator does not need to make the through hole 24a in the side member 24, and the workability is good.

  However, since there may be installation conditions in which piping cannot be pulled out from the side, the lower surface portion 103 of the casing 10 is preferably a resin member. This is because drilling at the installation site is possible and it is convenient for the installation operator.

  In addition, since it is not rational to manufacture separate molds for the first and second forms of the side member 24, the mold for molding the side member 24 corresponds to the through hole 24a of the first form. It is preferable that a nesting fixing portion for incorporating the nesting is provided at a position where the nesting is performed.

  Fig.7 (a) is a fragmentary sectional view of the resin molding die of the 2nd layer part corresponding to the 1st form of a side member, (b) is the 2nd layer part corresponding to the 2nd form of a side member. It is a fragmentary sectional view of this resin molding die. 7A and 7B, a mold 300 is a resin molding mold common to both the first form and the second form. The mold 300 includes a nesting fixing portion 301 that can be incorporated in either the first nesting 401 or the second nesting 402.

  As shown in FIG. 7A, the first nest 401 has a pin portion 401a for forming the through hole 24a. Further, as shown in FIG. 7B, the second insert 402 does not have a pin portion like the first insert 401. Therefore, the second layer portion 242 formed by a mold in which the first insert 401 is fixed to the insert fixing portion 301 is used for the first form of the side member 24, and the second insert 402 is fixed to the insert fixing portion 301. The second layer portion 242 formed by the formed mold is used for the second form of the side member 24.

  Moreover, Fig.8 (a) is a fragmentary sectional view of the press die of the 1st layer part corresponding to the 1st form of a side member, (b) is the 1st layer corresponding to the 2nd form of a side member. It is a fragmentary sectional view of the press die of a part. 8A and 8B, a mold 350 is a press mold common to both the first form and the second form. The mold 350 includes a nesting fixing portion 351 that can be incorporated in either the first nesting 451 or the second nesting 452.

  As shown to Fig.8 (a), the 1st nest | insert 451 has the pin part 451a for forming the through-hole 24a. Further, as shown in FIG. 8B, the second insert 452 does not have a pin portion like the first insert 451. Therefore, the first layer portion 241 formed by a mold in which the first insert 451 is fixed to the insert fixing portion 351 is used for the first form of the side member 24, and the second insert 452 is fixed to the insert fixing portion 351. The first layer portion 241 molded with the molded mold is used for the second form of the side member 24. For this reason, compared with the case where a metal mold | die is provided for every form of a side member, metal mold | die cost is restrained low.

  As described above, according to the present invention, the pipe is drawn out from the side of the main body, which is useful when it is desired to avoid the previous trace of the pipe from being noticed by the transfer work or the like.
