[0006] Patent Document 1: Japanese Patent No. 6311308 Summary of the invention

[0007] Problems to be solved by the invention

[0008] Like furniture such as tables and sofas placed indoors, indoor units installed on the upper part of the wall will affect the aesthetics of the room. In addition, since it is installed protruding from the wall, it sometimes gives the user a sense of oppression. The front panel of the indoor unit of Patent Document 1 is made into a curved surface that protrudes toward the inner side of the room in the center and bends toward the wall on the left and right sides, thereby alleviating this sense of oppression. However, the left and right ends of the front panel are separated from the wall, so although the protrusion (size) is smaller than that of a flat front panel, it is still a shape that protrudes sharply from the wall.

[0009] An object of the embodiment is to provide an indoor unit of an air conditioner which has good aesthetics and can alleviate a sense of oppression when mounted on an upper wall surface.

[0010] The indoor unit of the air conditioner of technical solution 1 comprises: an indoor unit body, which holds an indoor heat exchanger and an indoor fan and is mounted on a wall surface; and a front panel, which covers the front of the indoor unit body. The front panel includes a side portion and another side portion in a direction orthogonal to the up-down direction of the wall surface, and includes a central portion located between the one side portion and the other side portion. The one side portion and the other side portion have shapes that are bent from a portion connected to the central portion toward the wall surface, and a portion that is closer to the front of the bent portion extends to the position of the wall surface at an acute angle relative to the wall surface.

[0023] Hereinafter, one embodiment of the indoor unit of the present invention will be described with reference to the drawings.

[0024] like Figure 1 As shown, a mounting plate 2 made of a high-strength component such as a metal plate is installed on the indoor wall 1 by fastening with screws, and the mounting plate 2 is roughly positioned in the center and hung with a main body (also called a rear body) 10, and the lower part of the main body 10 is further fastened to the mounting plate 2 by screws as needed to fix it.

[0025] The main body 10 includes a plate-shaped rear plate 11 made of a synthetic resin molded part for installation on the installation plate 2, and various components such as an indoor heat exchanger 12, an indoor fan 13 described later, and an electrical component box 14 are installed at a predetermined position of the rear plate 11. The rear plate 11 has a rectangular shape that is long in a direction (left-right direction) perpendicular to the vertical direction of the wall surface 1, and has a predetermined thickness in a direction away from the wall surface 1.

[0026] After the main body 10 is mounted on the mounting plate 2, as shown in FIG. Figure 2 As shown, a sub-body (also referred to as a front body or a front cover) 20 made of a synthetic resin molded part is installed so as to cover the front side of the main body 10. During this installation, the sub-body 20 is firmly fixed and held to the rear plate 11 by inserting the inner periphery of the sub-body 20 into the outer periphery of the rear plate 11 and screws (not shown) are omitted. The indoor unit body 80 is formed by these main body 10 and sub-body 20.

[0027] like Figure 3 As shown in the enlarged form in FIG. 1 , the replica body 20 includes a side portion (left side portion) 21 and another side portion (right side portion) 22 in a direction (left-right direction) perpendicular to the vertical direction of the wall surface 1, and includes a central portion 23 located between the side portion 21 and the other side portion 22. Figure 2 As shown, one side portion 21 and the other side portion 22 have shapes that are bent toward the wall surface 1 from a portion connected to the center portion 23 , and a portion forward of the bent portion extends to the wall surface 1 at an acute angle relative to the wall surface 1 .

[0028] Specifically, if Figure 4 As shown, one side portion 21 includes a side surface 21a and a flat side surface 21b, the side surface 21a is curved from a portion connected to the central portion 23 to the wall surface 1 with a curvature of radius R1, the side surface 21b extends from the side surface 21a to the position of the wall surface 1, and the end edge approaches or abuts against the wall surface 1 at an acute angle Q1. The other side portion 22 includes a side surface 22a and a flat side surface 22b, the side surface 22a is curved from a portion connected to the central portion 23 to the wall surface 1 with a curvature of radius R2, the side surface 22b extends from the side surface 22a to the position of the wall surface 1, and the end edge approaches or abuts against the wall surface 1 at an acute angle Q2.

[0029] The radius R1 and the radius R2 are set to be equal to each other and are equal to or less than approximately 85 degrees. The acute angle Q1 and the acute angle Q2 are set to be equal to each other and are equal to or less than approximately 53 degrees.

[0030] like Figure 3 and Figure 4 As shown, the sub-body 20 includes an upper portion 24 extending from the upper edges of each of the one side portion 21, the central portion 23, and the other side portion 22 to the wall surface 1 side and in contact with the wall surface 1, and includes a lower portion 25 extending from the lower edges of each of the one side portion 21, the central portion 23, and the other side portion 22 to the wall surface 1 side and in contact with the wall surface 1. In addition, the sub-body 20 has an air intake port 26 from the central portion 23 to the upper portion 24, and a mesh filter 27 for dust removal is detachably held at a position corresponding to the air intake port 26. In addition, the sub-body 20 has an air outlet 28 at the lower portion 25. Along with being mounted on the main body 10, the air outlet 28 is closed by a vertical baffle 17 of the main body 10 described later so as to be openable and closable.

[0031] In the upper surface portion 24 of the secondary body 20, a portion connected to the side surface 21a of the one side portion 21 has a curved shape along the curved shape of the side surface 21a, and a portion connected to the side surface 21b of the one side portion 21 has a straight shape along the plane shape of the side surface 21b. In the upper surface portion 24 of the secondary body 20, a portion connected to the side surface 22a of the other side portion 22 has a curved shape along the curved shape of the other side portion 22, and a portion connected to the side surface 22b of the other side portion 22 has a straight shape along the plane shape of the side surface 22b. The upper portions of each of the one side portion 21 and the other side portion 22 are connected to the upper surface portion 24 with a gentle inclination.

[0032] Similarly, in the lower portion 25 of the secondary body 20, a portion connected to the side surface 21a of the one side portion 21 has a curved shape along the curved shape of the side surface 21a, and a portion connected to the side surface 21b of the one side portion 21 has a straight shape along the planar shape of the side surface 21b. In the lower portion 25 of the secondary body 20, a portion connected to the side surface 22a of the other side portion 22 has a curved shape along the curved shape of the other side portion 22, and a portion connected to the side surface 22b of the other side portion 22 has a straight shape along the planar shape of the side surface 22b.

[0033] Two insertion holes 29 are formed on the side 21b of the one side portion 21, and two insertion holes 29 are formed on the side 22b of the other side portion 22. Fixing members such as screws 40 are inserted through these insertion holes 29. The inserted screws 40 pass through the notches 11a formed at the four corners of the rear plate 11 of the main body 10, and are screwed into four positions 1a on the upper part of the wall surface 1. Through the screwing of these screws 40, the end edges of the side 21b of the one side portion 21 and the side 23b of the other side portion 22 are pressed against the wall surface 1 in a state where the four corners of the rear plate 11 of the main body 10 are sandwiched between the wall surface 1, and the main body 10 and the sub-body 20 are fixed to the wall surface 1 in a mutually connected state. That is, the assembly of the main body 10 and the sub-body 20, that is, the indoor unit body 80, can be fixed in a state of being closely attached to the wall surface 1 without floating from the wall surface 1. The indoor unit body 80 and the front panel 30 described later have their ends on both sides extended to the wall surface 1, so they are long in the left-right direction. In addition, the mounting plate 2 is made smaller in lateral width to reduce the material as much as possible. The lateral dimension of the actual mounting plate 2 is roughly the same as the width dimension of the indoor heat exchanger 12 or the indoor fan, or is shorter than it. Therefore, the two sides of the indoor unit body 80 extend to the side more significantly than the mounting plate 2. Therefore, the two sides of the indoor unit body 80 are easy to float in the direction away from the wall surface 1. In response to this, by performing the screw fixing as described above, it is possible to prevent the indoor unit body 80 from floating relative to the wall surface 1. In addition, the fixing by the screw 40 can be implemented as needed according to the installation conditions.

[0034] In addition, depending on the material of the wall surface 1, it may be difficult to screw the screw 40 into the wall surface 1. Even in this case, since the outer peripheral edge of the rear plate 11 and the inner peripheral edge of the secondary body 20 are fastened and engaged by the screws, no large gap is generated between the end edges of the one side portion 21 and the other side portion 22 and the wall surface 1. Therefore, the additional fixing by the screw 40 is implemented as needed according to the installation situation.

[0035] As the sub-body 20 is mounted on the main body 10, the space inside the other side portion 22 becomes a storage space for the electrical component box 14. The side surface 22a of the other side portion 22 has an opening 22c for exposing the cover of the electrical component box 14. The cover of the electrical component box 14 can be opened and closed through the opening 22c. The electrical component box 14 matches the curved shape of the side surface 22a of the other side portion 22 and is mounted in a state inclined relative to the thickness direction of the main body 10.

[0036] In addition, if Figure 3As shown, the lower portion 21ax of the side surface 21a of the one side portion 21, the lower portion 21bx of the side surface 21b, the lower portion 23x of the central portion 23, the lower portion 22ax of the side surface 22a of the other side portion 22, and the lower portion 22bx of the side surface 22b become the mounting area of ​​the strip-shaped elastic member 70 described later. In addition, only the lower portion 23x of the central portion 23 may be set as the mounting area of ​​the strip-shaped elastic member 70.

[0037] In addition, if Figure 3 As shown, the lower portion 21ax of the side 21a, the lower portion 23x of the central portion 23, and the lower portion 22ax of the side 22a are respectively formed with locking holes 71 at positions above the region where the elastic member 70 is installed. Fig.10 The locking claws 35 shown are inserted into these locking holes 71 and are loosely held.

[0038] After the sub-body 20 is mounted on the main body 10, a white, milky white or light yellow front panel (also called a decorative panel or grille panel) 30 made of an integrally formed synthetic resin is mounted to cover the front side of the sub-body 20. In this way, the indoor unit of the air conditioner is composed of the main body 10, the sub-body 20 and the front panel 30. The front panel 30 has a side portion 31, a center portion 33, and another side portion 32 that are substantially the same in shape as the side portion 21, the center portion 23, and the other side portion 22 of the sub-body 20, and is mounted to the sub-body 20 in a detachable manner through a pair of ribs 34, 35 mounted on the upper edge of the front panel 30.

[0039] Figure 4 The figure shown at the top of FIG. 1 is a figure showing a state where the indoor unit main body (main body 10+sub body 20) 80 is mounted on the wall surface 1 as viewed from above. Figure 4 The figure shown in the middle part of is a figure observing the state where the entire indoor unit (main body 10+sub body 20+front panel 30) is installed on the wall surface 1 from the front. Figure 4 The figure shown at the bottom of FIG. 1 is a figure showing a state where the entire indoor unit is mounted on the wall surface 1 as viewed from below.

[0040] In the front panel 30, the side portion 31 includes a curved side 31a which is the same as the side 21a of the side portion 21 of the replica body 20, and includes a flat side 31b which is the same as the side 21b of the side portion 21 of the replica body 20. That is, the side portion 31 includes a side 31a which is curved toward the wall surface 1 at a curvature of a radius R1 from a portion connected to the central portion 33, and a flat side 31b which extends from the side 31 to the position of the wall surface 1, and the end edge of the side 31b approaches or abuts against the wall surface 1 at an acute angle Q1. The central portion 33 has the same planar shape as the central portion 23 of the replica body 20. The other side portion 32 includes a curved side 32a which is the same as the side 22a of the other side portion 22 of the replica body 20, and includes a flat side 32b which is the same as the side 22b of the other side portion 22 of the replica body 20. That is, the other side portion 32 includes a side surface 32a and a planar side surface 32b, wherein the side surface 32a is bent toward the wall surface 1 with a curvature of a radius R2 from a portion connected to the central portion 33, and the side surface 32b extends from the side surface 32a to the position of the wall surface 1, and the end edge approaches or abuts against the wall surface 1 at an acute angle Q2.

[0041] In addition, although the central portion 33 is set to a flat shape, it can also be set to a gentle curved surface with a large curvature in the left-right direction. In addition, regarding the connection portion between the side surface 31a and the side surface 31b, the connection portion between the side surface 31b and the central portion 33, the connection portion between the side surface 32a and the side surface 32b, and the connection portion between the side surface 32b and the central portion 33, the lines along the up-down direction indicating the connection portion are drawn in the drawings, but the connection portions of the multiple surfaces actually have a roughly smooth curved surface shape. Therefore, the changes in the curvature and surface shape of the surface of each connection portion are basically not conspicuous, and no clear lines appear in the appearance of each connection portion.

[0042] like Figure 3As shown in the figure, the ribs 34 and 35 for mounting the front panel 30 on the secondary body 20 have protrusions 34a and 35a for locking at the front end. When mounting on the secondary body 20, as shown by the thick arrows, the ribs 34 and 35 are pushed in opposite directions by human operation while being inserted into the slit 41 formed on the upper part of the one side 21 of the secondary body 20 and the slit 42 formed on the upper part of the other side 22. After the insertion, if the operation of pushing the ribs 34 and 35 is released, the ribs 34 and 35 return to the original state due to the elasticity of the synthetic resin itself. With this, the protrusions 34a and 35a of the ribs 34 and 35 are engaged with the locking parts on the inner side of the slits 41 and 42, and the upper edge of the front panel 30 is freely rotatably locked on the upper part of the secondary body 20. By pressing the front panel 30 toward the central portion 23 of the secondary body 20 in this locked state, and inserting the later-described locking claws 35 existing in the lower portion of the back side of the front panel 30 into the locking holes 71 of the secondary body 20 and engaging with the later-described hooks 72, the front panel 30 is installed relative to the secondary body 20. In the state where the front panel 30 is installed to the secondary body 20, the left and right ends of the front panel 30, that is, the left and right ends of the side surfaces 31b and 32b, are in contact with the wall surface, or extend to the wall surface 1 to a position where there is only a very small gap.

[0043] On the other hand, the engagement between the locking claw 35 and the hook 72 is a loose engagement maintained by the elasticity of the locking claw 35 and the hook 72 made of synthetic resin, so the front panel 30 can be easily removed from the secondary body 20 by performing the operation opposite to that during installation.

[0044] As described above, the main body 10, the sub-body 20 and the front panel 30 constitute the indoor unit.

[0045] One side portion 31 and the other side portion 32 of the front panel 30 are respectively bent from the portion connected to the central portion 33 toward the wall surface 1 side, and the portion in front of the bent portion extends to the wall surface 1 at an acute angle relative to the wall surface 1. Therefore, in appearance, the indoor unit is integrated with the wall surface 1 in a manner that it bulges smoothly from the wall surface 1 and is roughly flush with the wall surface 1. In addition, even if the indoor lighting shines on the indoor unit, it is difficult to produce a shadow of the indoor unit on the wall surface 1. These points improve the aesthetics of the indoor unit and can greatly alleviate the sense of oppression of the indoor unit installed on the upper part of the wall surface on the user.

[0046] Moreover, when the indoor unit is installed on the wall, the indoor unit body 80, that is, the front of the sub-body 20 in the indoor direction is covered by the front panel 30 as a whole. Therefore, compared with the previous situation that only the front of the indoor unit body is covered by the front panel 30 and the two sides of the body 80 are exposed to the room, the left and right sides of the indoor unit body 80 are covered by the front panel 30 as a whole, so the two sides of the indoor unit body 80 will not be dirty by dust, etc. Instead, dust, etc. will adhere to the front of the front panel 30, but the front panel 30 is composed of a smooth surface all the way to the wall, which is easy to clean, and can be easily removed in the case of serious dirt, and can be washed with tap water, etc. after removal, which is more hygienic.

[0047] [About fabric parts]

[0048] The front panel 30 can be used as is, but can be installed as needed. Figure 5 The decorative fabric (cloth) component 50 shown. The fabric component 50 has a rectangular shape of substantially the same size as the front panel 30, and by being installed on the front panel 30 to cover the surface of the front panel 30, the fabric component 50 of various colors and patterns can be prepared to further improve the aesthetics of the indoor unit.

[0049] Thus, by selecting the fabric member 50 , it is possible to match the color tone to blend into the wall surface so as to be inconspicuous, or conversely make it conspicuous.

[0050] When installing the fabric component 50, a strip-shaped four-sided Velcro (first-sided Velcro) 61 is installed at the periphery of the back side of the fabric component 50 by, for example, sewing with thread, and a four-sided Velcro (second-sided Velcro) 62 is also installed at the periphery of the back side of the front panel 30 by, for example, double-sided tape.

[0051] That is, Figure 6 As shown in FIG. 1 , a strip-shaped surface fastener 61 is sewn to one side edge 51, the other side edge 52, the upper edge 53, and the lower edge 54 of the back of the fabric member 50. Next, as shown in FIG. Figure 7 As shown in FIG. 1 , one side edge 51 and the other side edge 52 of the fabric member 50 are bent from the front side to the back side, and then Figure 8 As shown in the figure, the upper edge 53 and the lower edge 54 of the fabric member 50 are bent from the front side to the back side. Then, the two ends of the bent piece of the upper edge 53 are sewn and joined to the overlapping parts 55 and 56 of the one side edge 51 and the other side edge 52, and the two ends of the bent piece of the lower edge 54 are sewn and joined to the overlapping parts 57 and 58 of the one side edge 51 and the other side edge 52.

[0052] By folding and sewing, pockets are formed on the four sides of the back side of the fabric component 50 for mounting to the front panel 30 , and the surface fastener 61 on the inner side of the pocket is placed opposite to the back side of the fabric component 50 .

[0053] The surface fastener 61 is, for example, a ring-shaped fastener formed by many ring-shaped fibers arranged in a ring shape, and the surface fastener 62 is, for example, a hook-shaped fastener formed by many hook-shaped fibers arranged in a ring shape. By pressing the two together, the two are engaged with each other, and by pulling the two apart, the engagement between the two can be released.

[0054] When the fabric component 50 is installed on the front panel 30, the periphery of the front panel 30 is received into the bag-shaped portion of the fabric component 50, and the folded piece of the periphery of the fabric component 50 is pressed against the periphery of the front panel 30, so that the surface fastener 61 on the side of the fabric component 50 is engaged with the surface fastener 62 on the side of the front panel 30. Through this engagement, the fabric component 50 can be firmly installed on the front panel 30. It is advisable to use a fabric with low elasticity for the fabric component 50. If the elasticity is high, it is difficult to install it on the front panel 30. However, the fabric with low elasticity will cause the fabric to be easily twisted or wrinkled during assembly. However, with respect to the front panel 30 of this embodiment, the R of its curved surface portion is large, and the inclination to the wall surface 1 is also relatively gentle, and the installation surface of the fabric component 50 becomes a convex surface. Furthermore, the front panel 30 is an integrally molded part of synthetic resin, and the material itself undergoes elastic deformation and has a restoring force to return to its original shape, so that the fabric component 50 is unlikely to be twisted or wrinkled after installation and can be installed neatly and simply.

[0055] The state where the front panel 30 with the fabric member 50 is installed on the secondary body 20 and the structure in the main body 10 are shown in cross section. Fig. 9 In Fig. 9 The engagement state of the surface fasteners 61 and 62 is shown in an enlarged manner. Fig.10 middle. Fig. 9 and Fig.10 Each of them is a longitudinal section at a substantially central portion of the indoor unit.

[0056] The main body 10 forms the indoor heat exchanger 12 into a "コ" shape folded into three from the front to the back, and an indoor fan 13 is arranged on the inner side of the indoor heat exchanger 12, and left and right baffles 16 and up and down baffles 17 are arranged in sequence on the air path from the indoor fan 13 to the air outlet 28.

[0057] The lower portions 21ax, 21bx, 23x, 22ax, and 22bx of the sub-body 20 are provided with elastic members 70 made of a strip of sponge or the like, which are elastically deformable by being pressed and are substantially airtight.

[0058] The lower portions 21ax, 23x, and 22ax of the elastic member 70 are provided with the same Figure 3 The locking holes 71 shown are such that when the front panel 30 is mounted on the secondary body 20, a plurality of protruding locking claws 35 formed on the back side of the front panel 30 enter these locking holes 71. The locking claws 35 that have entered overcome the elastic biasing force of the hooks 72 disposed at positions corresponding to the locking holes 71 to temporarily push the hooks 72 upward, and engage with the hooks 72 under the elastic restoring force of the pushed hooks 72. Through this engagement, the installation of the front panel 30 relative to the secondary body 20 is completed.

[0059] When the front panel 30 with the fabric member 50 attached is attached to the secondary body 20, at least the outer peripheral surface of the folded piece of the bag-shaped portion of the fabric member 50 abuts against the elastic member 70, and the ventilation into the secondary body 20 is cut off by this abutment. Fig.10 As shown by the middle arrow, even if the air blown out from the air outlet 28 and the surrounding air want to flow into the lower part of the secondary body 20, this undesirable situation of these air flowing into the secondary body 20 and the main body 10 can be prevented. Thus, unnecessary condensation in the secondary body 20 and the main body 10 can be avoided.

[0060] The state where the front panel 30 without the fabric member 50 is mounted on the secondary body 20 is shown in cross section together with the structure in the main body 10. Fig.11 In Fig.11 The contact state between the surface fastener 62 and the elastic member 70 is shown in FIG. Fig.12 middle.

[0061] In this case, the peripheral edge of the back surface of the front panel 30 and the surface fastener 62 abut against the elastic member 70, and the ventilation into the secondary body 20 is cut off by this abutment. Fig.12 As shown by the middle arrow, even if the air blown out from the air outlet 28 and the surrounding air want to flow into the lower part of the sub-body 20, it is possible to prevent the air from flowing into the sub-body 20 and the main body 10. Fig.10 and Fig.12 By comparison, it can be seen that in the case where the fabric member 50 is installed Fig.10 In the case of Fig.12 In contrast, the elastic member 70 is compressed and thinned by the thickness of the fabric member 50. By using such a compressible elastic member 70, ventilation into the secondary body 20 can be cut off when the fabric member 50 is mounted on the front panel 30 and when the fabric member 5 is not mounted on the front panel 30.

[0062] In addition, when the fabric member 50 is attached to the front panel 30, dust and the like adhere to the fabric member 50 rather than the front panel 30. As described above, the fabric member 50 can be easily installed and removed, so when it is seriously dirty, the fabric member 50 can be removed from the front panel 30, and only the fabric member 50 can be washed or cleaned, which is more hygienic.

[0063] [Modifications]

[0064] In the above embodiment, the curvature of the side 21a of one side portion 21, i.e., the radius R1, and the curvature of the side 22a of the other side portion 22, i.e., the radius R2, are set to the same value, but may be set to different values ​​depending on the shape of the indoor space and the configuration position of the indoor unit.

[0065] In the above embodiment, the angle between the side surface 21b of the one side portion 21 and the wall surface 1, i.e., the acute angle Q1, and the angle between the side surface 22b of the other side portion 22 and the wall surface 1, i.e., the acute angle Q2, are set to the same value, but they may be set to different values ​​according to the shape of the indoor space and the configuration position of the indoor unit, etc. However, in such a modified example, the appearance of the indoor unit is asymmetrical in shape.

[0066] In addition, in the above embodiment, the surface fastener 61 installed on the fabric member 50 is set to a ring type, and the surface fastener 62 installed on the front panel 30 is set to a hook type, but the shape of the surface fastener can also be reversed. In the case of reversal, when the front panel 30 without the fabric member 50 is installed on the secondary body 20, the surface fastener that abuts against the elastic member 70 becomes a ring-shaped surface fastener installed on the front panel 30, and the abutment against the elastic member 70 becomes weak, which can improve the durability of the elastic member 70.

[0067] In addition, the above-mentioned embodiments and variations are proposed as examples and are not intended to limit the scope of the invention. The new embodiments and variations can be implemented in various other ways, and various omissions, rewrites, and changes can be made without departing from the scope of the invention. These embodiments and variations are included in the main purpose of the invention protection scope, and are included in the invention described in the claims and the scope of their equivalents.
