The air filter 10 is arranged above the suction grille 9, one end side of which is detachably supported by the case 3 via a rotary stopper 15 and the other end side of which is held by a holding portion 16 formed on the case 3. It is hooked on and off.

[0008]

[Problems to be solved by the device]

 However, according to the above-described conventional configuration, since the suction grill 9 and the air filter 10 are supported by different support members, the number of parts is large, the number of molding and assembly processes is large, and the manufacturing cost is high. In addition, the structure is complicated and it takes a relatively long time to attach and detach the air filter.

The present invention has been made in view of such a situation, and the supporting members for the suction grill and the air filter are made common, thereby reducing the number of parts, reducing the manufacturing cost and simplifying the structure. It is an object of the present invention to provide a ceiling-embedded air conditioner that can be attached and detached easily.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a ceiling-embedded air conditioner in which an air filter and a suction grill are supported vertically on a lower surface of a case of an indoor unit that is buried in the ceiling. Each one end side of the suction grille is removably hooked to the stepped hooking portion of one elastic support plate that is hung below the case, and the other end side of the suction grill is hinged to the case. The air filter is rotatably supported, and the other end of the air filter is removably hooked on the holding portion of the case.

[0011]

[Action]

 When opening and closing the suction grille, first, the lower end of the support plate is elastically moved in a direction away from the suction grille, and one end of the suction grille is disengaged from the hook portion of the support plate. As a result, the suction grill becomes vertically rotatable on one end side with the hinge portion on the other end side serving as a fulcrum.

Therefore, one end of the suction grill can be opened by rotating it downward, and can be closed by rotating it upward and hooking it on the support plate.

On the other hand, when attaching or detaching the air filter, first, the suction grill is opened. Then, when removing the air filter, the air filter is curved or slid toward the other end side so that one end thereof is separated from the support plate. With this, when the support on one end side of the air filter is released, the other end side may be pulled out from the holding portion of the case while rotating the one end side downward.

In addition, when inserting the air filter, contrary to the above, after the other end side is hooked to the holding portion, one end side is raised and when it is raised to the position of the hooking portion of the support plate, It may be curved or slid toward the other end, and one end thereof may be supported by the hook portion.

Therefore, according to the present invention, since the supporting member for supporting the suction grill and the one end side of the air filter is made common, the number of parts can be reduced as compared with the conventional one, thereby reducing the manufacturing cost and the structure. In addition, the air filter can be easily attached / detached, and the required functionality at the time of use such as filter replacement can be sufficiently ensured.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

Since the overall schematic configuration is the same as that shown in FIG. 5, this figure is also used for the description of the present embodiment, and the description of the same components as the conventional one will be omitted.

In the present embodiment, as shown in FIGS. 1 and 2, the suction grille 9 and the air filter 10 which are provided in parallel at the lower part of the case 3 of the indoor unit in parallel in the upper and lower sides have a common end (left end) side. It is supported by one support plate 21.

The support plate 21 is made of an elastic material and has an inverted L-shaped cross section. The upper piece 21 a is fixed to the lower surface of the case 3 by a fitting 22 such as a screw, and the hanging piece 21 b is attached to the suction port 8. It is located at the side edge and protrudes below the case 3.

On the surface of the hanging piece portion 21b on the suction port 8 side (right side), upper and lower stepped hooking portions 23 and 24 are formed, and the lower end of the hanging piece portion 21b is gradually thinned. It has a taper shape.

Then, one end of the air filter 10 is hooked on the upper hook 23 and one end of the suction grill 9 is hooked on the lower hook 24.

The other end of the suction grill 9 is in contact with the panel 5 of the case 3 and has a hinge 25 on the other end thereof. The hinge portion 25 is configured such that, for example, a curved locking member 25a inserted into a hole of the panel portion 5 is used as a supporting means, and a portion of the other end portion of the suction grill 9 which is in contact with the panel portion 5 serves as a fulcrum. As a result, one end side of the suction grill 9 can be rotated in the vertical direction.

On the other hand, the other end side (right end side) of the air filter 10 is removably hooked while being inserted into a channel-shaped holding portion 26 formed at the lower end of the case 3. The air filter 10 may be configured to be elastically bendable, or may be slidable to the other end side in the holding portion 26, for example, so that one end side portion is pressed toward the other end side. The one end side of the support plate 21 can be removed from the hook portion 23 of the support plate 21.

Further, as shown in FIG. 1, the air filter 10 is composed of a net portion 10a and a frame 10b having a substantially U-shaped cross section that fits and holds a peripheral portion of the net portion 10a. The frame 10a is made of aluminum, for example, and is integrally joined to the peripheral portion of the net portion 10a with a hot melt adhesive 27.

If the inner surface of the frame 10b is flat, the hot melt adhesive 27 has problems such as flowing out at the time of filling and peeling at the joint after solidification due to its weak adhesion to aluminum. Therefore, in this embodiment, a protrusion 28 is provided on the inner surface of the frame 10b by extrusion molding, the net 10a and the frame 10b are combined, and then the hot melt adhesive 27 is injected and solidified inside the protrusion 28. Are joined together.

As a result, the hot melt adhesive 27 is prevented from flowing out at the time of injection and is filled with the protrusions 28 as boundaries, so that the adhesive injection work can be performed easily and quickly, and the finished shape is improved. Also, even if the adhesive force with the frame 10b is weak, there is no risk of separation after solidification, and the adhered state can be secured, the immovable state can be maintained against external force, and noise such as chatter noise due to vibration is also effective. To prevent it.

Next, the operation will be described.

When opening and closing the suction grille 9, first, the lower end of the hanging piece portion 21b of the support plate 21 is pushed in the direction away from the suction grille 9, that is, to the left to elastically deform the suction grille 9. One end of the grill 9 is removed from the hook 24. As a result, the suction grill 9 is in a state in which one end side is vertically rotatable about the hinge portion 25 on the other end side as a fulcrum.

Therefore, as shown in FIG. 3, it can be opened by rotating one end side of the suction grill 9 downward, and as shown in FIG. 2, it is rotated upward to support plate 21. It can be closed by hanging it on.

On the other hand, when the air filter 10 is attached or detached, the suction grill 9 is opened as shown in FIG. When removing the air filter 10, the air filter 10 is curved or slid toward the other end so that one end thereof is separated from the support plate 21. As a result, when one end side of the air filter 10 is released from the hook portion 23, the other end side is rotated from the holding portion 26 of the case 3 while rotating the one end side downward as shown by a phantom line in FIG. Just pull it out.

Further, when the air filter 10 is inserted and attached, the other end side is hooked on the holding part 26, and then one end side is raised to the position of the hooking part 24 of the support plate 21. When it rises, it may be curved or slid toward the other end, and one end thereof may be supported by the hook portion 24.

According to the present embodiment, one end of the suction grill 9 and one end of the air filter 10 are commonly supported by the single supporting member 21, so that the number of parts can be reduced as compared with the conventional one, and thus, the manufacturing is possible. The cost can be reduced and the structure can be simplified.

Moreover, the opening / closing of the suction grille 9 and the attaching / detaching operation of the air filter 10 can be easily performed, and the necessary functionality at the time of use for filter replacement can be sufficiently ensured.

In this embodiment, since the lower end of the hanging piece 21 of the support plate 21 is tapered, the tapered surface serves as a guide when the suction grill 9 is closed or the air filter 10 is inserted. Work can be done smoothly.
