The structure is fixed to the decorative panel.

Japanese Unexamined Patent Publication No. 2000-104944

The suction port structure of Patent Document 1 uses a hanging structure such as a reel or a wire, but in order to reduce the cost and the labor of construction, such a hanging structure is not used. It is preferable to fix the suction port structure only by locking. However, as in Patent Document 1, in a locking form in which the convex portion of the elastic member is hooked on the elastic member engaging hole and the suction port structure hangs from the decorative panel, the suction port structure is generated due to the influence of dimensional tolerance or the like. Since there is a vertical gap between the air conditioner and the decorative panel, the suction port structure may vibrate up and down due to vibration of the motor that rotates the fan of the air conditioner, causing noise. ..

An object of the present invention is to provide an air conditioner capable of suppressing the generation of noise due to rattling of a decorative member even when the decorative member exposed on the indoor side is fixed by locking.

In order to solve the above problems, the air conditioner according to the present invention is an air conditioner installed on the ceiling and having a built-in motor for rotating a fan, and is a main body of the air conditioner and a decorative member exposed to the indoor side. A decorative member having a locking portion that protrudes upward from the back surface side of the decorative member, and an attached member that is attached to the ceiling and the decorative member is locked and fixed, and the engagement of the decorative member. A mounted member having an opening in which a stop portion is locked is provided, and the locking portion has a plurality of bulging portions that bulge outward at a tip portion on the upper side. The ceiling and the attached member are configured to be sandwiched between the bulging portion and the peripheral edge portion of the decorative member, and the lower surface of the bulging portion is inclined downward toward the outside. And.

In the air conditioner according to the present invention, since the lower surface of the bulging portion is inclined downward toward the outside, as compared with the case where the lower surface of the bulging portion is not inclined downward toward the outside of the opening. , The shortest distance in the vertical direction between the lower end of the bulging portion and the peripheral edge portion of the decorative member can be kept small. As a result, the attached member and the ceiling can be sandwiched between the bulging portion and the decorative member. By creating the sandwiched state in this way, even if vibration is generated by the motor of the fan or the like, it is possible to suppress the rattling of the decorative member in the vertical direction, so that the generation of noise can be suppressed.

Further, in the air conditioner according to the present invention, it is also preferable that the locking portion connects the bulging portion and the back surface of the decorative member and has a leg portion having a bent portion in a part thereof. ..

In this preferred embodiment, since the bent portion is formed between the bulged portion and the back surface of the decorative member in the locking portion, when the bulged portion is inserted into the opening, the bent portion is deformed into a leg portion centered on the bent portion. Can be caused. Therefore, the deformation can be caused not at the base of the leg but at a position closer to the bulge in the leg. As a result, when the bulging portion of the locking portion is inserted into the opening, it becomes easy to temporarily raise and incline the lower surface of the bulging portion outward. Therefore, when the bulging portion is inserted into the opening, the locking portion can be locked to the opening with a smaller insertion amount, and the locking workability can be improved.

Further, in the air conditioner according to the present invention, the locking portion is provided on the inner side of the peripheral portion of the decorative member and closer to the peripheral edge portion, and the plurality of bulging portions are provided on the decorative member. The locking portion is provided so as to face each other along the outer peripheral direction, and the locking portion has a leg portion connecting the bulging portion and the back surface of the decorative member, and the lower surface of the bulging portion is an outer surface of the decorative member. It is also preferable that the inner side is located lower than the side.

In this preferred embodiment, the stress concentration on the outer surface portion of the lower surface of the bulging portion, which is closer to the peripheral edge portion of the decorative member, can be relaxed, and the stress applied to the leg portion can be equalized.

Further, in the air conditioner according to the present invention, in a state where the plurality of bulges are locked to the openings, the plurality of bulges are not reduced in distance between the plurality of bulges. It is also preferable to provide a separation distance regulating member that maintains the separation distance between the parts to a predetermined distance or more.

In this preferred embodiment, the separation distance regulating member prevents the tip ends of the plurality of bulges locked in the openings from being displaced inward, so that the lower end of the bulge and the decorative member It is possible to prevent the vertical distance from the peripheral portion from becoming large. Therefore, it is possible to suppress rattling of the decorative member in the vertical direction for a long period of time.

According to the air conditioner of the present invention, even when the decorative member exposed to the indoor side is fixed by locking, it is possible to suppress the generation of noise due to the rattling of the decorative member.

Further, the two bulging portions 21 are locked to one corresponding opening portion 19, and the bulging portion 21 opens in a state where the locking portion 17 is locked to the opening portion 19. It is configured to bulge outward from the portion 19. The outer surface 212 of the bulging portion 21 that bulges outward from each other in this way is located outside the outer surface of the leg portion 23. Further, the lower surface 211 of the bulging portion 21 is configured to be inclined downward toward the outside.

The leg portion 23 has a bent portion 25 substantially at the center in the height direction. In the pair of legs 23, the distance between the lower part below the bent part 25 (on the root side) is smaller than the distance between the upper part above the bent part. The upper part of the leg portion 23 is bent outward from the lower part.

A corner is formed between the lower surface of the bulging portion 21 and the outer surface of the leg portion 23.

The leg portion 23 has elasticity and functions like a leaf spring that elastically deforms when an external force is applied to the bulging portion 21.

As shown in FIG. 5, the locking portion 17 is provided with a connecting tool 27 as a separation distance regulating member. The connector 27 connects the pair of bulging portions 21 so that the separation distance between the pair of bulging portions 21 locked to the opening 19 does not change. Here, the separation distance represents a distance between arbitrary portions located at the same height on the inner surface or the outer surface of the pair of bulging portions 21.

The connector 27 is integrally molded with the bulging portion 21 of any one of the pair of bulging portions 21. That is, the connector 27 is integrally molded with the same resin material as the locking portion 17. The connector 27 may be configured separately from the locking portion 17.

FIG. 6 is a side view on the right side of the locking portion 17 shown in FIG.

With the locking portion 17 locked to the opening 19 of the attached member 11, the lower surface 211 of the bulging portion 21 comes into contact with the upper surface of the peripheral edge of the opening 19 of the attached member 11. The broken line shown in FIG. 6 represents the position of the upper surface of the attached member 11.

In FIG. 6, the right side of the locking portion 17 is the inner side of the frame-shaped attached member 11 and the frame-shaped decorative member 9, and the left side is the outer side of the attached member 11 and the decorative member 9. When the bulging portion 21 is viewed from the outer surface side, the lower surface 211 of the bulging portion 21 is inclined with respect to the upper surface (broken line) of the attached member 11, and is inside the lower surface 211 of the bulging portion 21. The side portion 211b is located below the outer portion 211a. The inclination angle of the lower surface 211 of the bulging portion 21 with respect to the upper surface of the attached member 11 is, for example, 1 ° or less. If the inclination of the lower surface 211 is formed by a draft that always occurs when the decorative member 9 is integrally molded by injection molding, it is not necessary to perform post-processing to provide the inclination after molding, which increases the manufacturing cost. It can be suppressed. Further, when the lower surface 211 is inclined by such a method, it is preferable to set the inclination angle of the lower surface 211 to 0.5 ° or more in consideration of the ease of removing the molded product from the mold.

Subsequently, a method of locking the locking portion 17 to the opening 19 will be described.

7 (a) to 7 (c) are schematic views for explaining a method of locking the locking portion 17 of the decorative member 9 with the opening 19 of the attached member 11. FIG. 7A shows a state before the bulging portion 21 is inserted into the opening 19. FIG. 7B shows a state after the bulging portion 21 is inserted into the opening 19. FIG. 7C shows a state in which two bulging portions 21 locked to the opening 19 are connected by a connecting tool 27.

As shown in FIG. 7A, before the locking portion 17 is inserted into the opening 19, the two bulging portions 21 are brought into a second state in which they are not connected by the connecting tool 27.

Subsequently, the locking portion 17 is inserted into the opening 19 so that the two bulging portions 21 enter the opening 19. At that time, as shown by the broken line in FIG. 7B, the outer surface 212 of the two bulging portions 21 comes into contact with the peripheral edge 20 of the opening 19, and the separation distance between the two bulging portions 21 decreases as they are inserted. As a result, the two bulging portions 21 are inserted into the opening 19. The change in the separation distance between the two bulging portions 21 is caused by the bending degree of the bending portion 25 becoming smaller (the bending becomes looser) due to the elastic deformation.

As shown by the solid line in FIG. 7B, after the two bulging portions 21 enter the opening 19, the elastically deformed bent portion 25 is restored to the original degree of bending, and the two bulges are restored. When the lower surface 211 of the portion 21 rides on the upper surface of the attached member 11, the lower surface 211 of the bulging portion 21 is caught on the peripheral edge 20 of the opening 19, and the locking portion 17 is locked to the opening 19. ..

Then, as shown in FIG. 7C, the connecting tool 27 is rotated to fit the fitting concave portion 28 of the connecting tool 27 and the fitting convex portion 22 provided at the upper end of the bulging portion 21. By connecting the two bulging portions 21 (first state), the locking operation of the locking portion 17 to the opening 19 is completed.

8 (a) to 8 (c) are schematic views for explaining a method of attaching the decorative member 9 to the attached member 11. FIG. 8A shows a state before the locking portion 17 is inserted into the opening 19, and FIG. 8B shows the state after all the locking portions 17 are inserted into the corresponding openings 19. The state is shown, and FIG. 8C shows a state after connecting the two bulging portions 21 in each of the locking portions 17 by the connecting tool 27.

By locking all the locking portions 17 to the corresponding openings 19 in the order shown in FIG. 8, the decorative member 9 is attached to the attached member 11 which is previously fixed to the peripheral edge portion 31 of the opening 29 by a screw or the like. Can be locked and fixed.

The work of fixing the attached member 11 to the ceiling 3 and the work shown in FIGS. 7 (a) to 7 (c) and 8 (a) to 8 (c) are performed before the ceiling 3 is assembled to the upper part of the bathroom 1. Will be. Therefore, the work of inserting the bulging portion 21 into the opening 19 and the work of connecting the two bulging portions 21 by the connecting tool 27 can be performed at the operator's hand.

FIG. 9 is an enlarged view of a portion B surrounded by a broken line in FIG. 8 (c). Further, FIG. 10 is a side sectional view of the locking portion 17 of FIG. 8C when the air conditioner 5 is attached to the ceiling 3 as viewed from the right side. As shown in FIGS. 9 and 10, the outer end of the flange portion 12, which is the peripheral edge of the frame-shaped decorative member 9, is pressed against the surface of the ceiling 3 at the peripheral edge of the ceiling opening 29. The lower surface of the flange portion 12 functions as a decorative surface that hides the edge of the ceiling opening 29.

Further, one locking portion 17 is provided on the inner side of the flange portion 12 of the decorative member 9 and at a position closer to the flange portion 12 (near the flange portion 12), and is shown in FIG. As described above, the outer end of the lower surface 211 of the bulging portion 21 is pressed against the upper surface of the attached member 11.

Therefore, the ceiling 3 and the attached member 11 are sandwiched between the flange portion 12 of the decorative member 9 and the lower surface 211 of the bulging portion 21. The restoring force due to the elastic deformation of the flange portion 12 gives a force to sandwich the ceiling 3 and the attached member 11 between the bulging portion 21 and the flange portion 12.

In the present embodiment, the ceiling 3 and the attached member 11 are sandwiched between the bulging portion 21 whose lower surface 211 is inclined outward and the flange portion of the decorative member 9 in this way. Even if the air conditioner main body 7 vibrates due to rotation, driving of a motor that rotates a fan, or the like, it is possible to suppress rattling of the flange portion 12 of the decorative member 9 in the vertical direction and suppress the generation of noise.

Further, in the present embodiment, in the locking portion 17, the bent portion 25 is formed between the bulged portion 21 and the back surface of the decorative member 9, so that the bent portion 21 is bent when the bulging portion 21 is inserted into the opening 19. The leg portion 23 can be deformed around the portion 25. Therefore, the deformation can be caused not at the base of the leg portion 23 but at a position closer to the bulging portion 21 in the leg portion 23. As a result, when the bulging portion 21 of the locking portion 17 is inserted into the opening 19, the lower surface of the bulging portion 21 temporarily rises outward as shown by the broken line in FIG. 7B. It becomes easier to make it tilted. Therefore, when the bulging portion 21 is inserted into the opening 19, the locking portion 17 can be locked to the opening 19 with a smaller insertion amount, and the locking workability can be improved.

Further, in the present embodiment, in a state where the plurality of bulging portions 21 are locked to the opening 19, the plurality of bulging portions 21 are separated from each other so that the separation distance between the plurality of bulging portions 21 is not reduced. A connecting tool 27 for maintaining the distance to a predetermined distance or more is provided. With such a simple configuration, in a state where the plurality of bulging portions 21 are locked to the opening 19, the plurality of bulging portions 21 locked to the opening 19 are displaced inward. Therefore, it is possible to prevent the decorative member from falling. Further, the shortest vertical distance L between the lower end of the bulging portion 21 and the flange portion 12 covering the peripheral edge portion 31 of the ceiling opening 29 in the decorative member 9 is aging due to deformation of the locking portion 17 or the like. It does not become large, and it is possible to suppress rattling of the decorative member 9 in the vertical direction for a long period of time.

Further, in the present embodiment, the connecting tool 27 is integrally formed with one of the two bulging portions 21, and the connecting tool 27 connects the two bulging portions 21. It is configured to rotate so that the first state and the second state in which the two bulging portions 21 are not connected can be selected. Therefore, when connecting the two bulging portions 21, there is no risk that the connecting tool 27 will fall or the connecting tool 27 will be lost, and thus the workability when attaching the decorative member 9 to the attached member 11 will be improved. be able to. Further, when the plurality of bulging portions 21 are inserted into the opening portion 19, the insertion is facilitated by setting the second state, and even when the connecting tool 27 is integrally formed with the bulging portion 21. Workability when engaging the decorative member 9 is not reduced.

Further, in the present embodiment, as shown in FIG. 10, the inner side portion 211b of the decorative member 9 on the lower surface 211 of the bulging portion 21 is positioned below the outer side portion 211a of the decorative member 9. ing. More specifically, the lower surface 211 of the bulging portion 21 is configured to be inclined downward from the outer side to the inward side of the decorative member 9 in a direction orthogonal to the outer peripheral direction of the decorative member 9. Therefore, the pressing force on the upper surface of the attached member 11 is higher in the inner side portion 211b than in the outer side portion 211a. The outer side portion 211a is floating from the upper surface of the attached member 11 or is in contact with the inner side portion 211b with a weaker force.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited thereto, and various modifications can be made based on the technical idea of the present invention. For example, the number of bulging portions 21 provided per one locking portion 17 is not limited to two. A plurality of bulging portions may be provided at predetermined intervals in the circumferential direction for each locking portion 17. In this case, the separation distance regulating member may be configured to maintain the separation distance of the plurality of bulging portions at a predetermined distance or more so that the plurality of bulging portions do not displace inward with each other.
