[0003]
[Problems to be solved by the invention]
However, in the above configuration, it is easy to remove the central panel for cleaning or the like, but the rotation shaft for opening and closing the central panel is a method of rotating around one axis. There is a problem in that the center panel cannot be extended to the outer side, and the center panel cannot be configured in a form other than a form covering only the center part of the decorative panel.
In the present invention, in view of the above-described problems, the central panel is supported by L-shaped links having rotation shafts at both ends, so that the entire lower part can be covered by the central panel, and cleaning is performed. An object of the present invention is to provide a ceiling-embedded air conditioner in which a central panel can be easily removed for reasons such as the above.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is provided with a panel provided with a suction port in the center and a blower outlet provided with a wind direction change plate on the four sides around the suction port on the lower surface of the main body casing embedded in the ceiling surface. The air passage connecting the suction port and the blower outlet formed in the main body casing surrounds the blower and the blower composed of a motor and a fan having a vertical drive shaft facing the suction port. In a ceiling-embedded air conditioner provided with a heat exchanger arranged as follows:
The panel is disposed in the lower part of the main body casing and has a square frame-like panel frame that pivotally supports the four-side wind direction changing plates, and a plurality of suction opening holes are formed in the center covering the lower part of the panel frame. And a central panel formed with rectangular outlets on the four sides and a decorative frame that surrounds the outer periphery of the central panel in a square frame shape,
A filter is disposed in the center of the back surface of the central panel, and a first shaft portion at one end of a pair of L-shaped links is pivotally supported on one side of the central panel so that the same pair of L-shaped links is provided. The second shaft portion at the other end of each of the two is detachably locked to a pair of locking claws formed on one side of the panel frame, and the second shaft portion is on the side between the pair of locking claws. It is the structure which provided the press convex part which protrudes in the direction.
[0005]
Further, provided on the back of the four corners of the central panel is a corner reinforcing bracket that reinforces the four corners by screwing on a screw boss formed on the back of the central panel. The first shaft portion of the L-shaped link is rotatably supported so as to be sandwiched between a U-shaped shaft support portion formed at one end and a rib formed on the back surface of the center panel.
[0006]
Further, the L-shaped link is constituted by the first shaft portion that connects both ends of the left and right L-shaped portions and the left and right L-shaped portions, and the second shaft portion including the pressing convex portion. The steel wire is bent and formed.
[0007]
Moreover, it has the structure which provided the linear finger hook part in the front end side of the said press convex part.
[0008]
Furthermore, it has the structure which faced | matched the both ends of the steel wire which forms the said L-shaped link in the approximate center of said 1st axial part.

[0012]
As shown in FIGS. 4, 6 and 7, 35 and 36 are at least left and right formed on one side of the panel frame 16 detachably locking the shaft portion 37 at the other end of the L-shaped link 30. A pair of locking claws and its locking projection.
Since the central panel 19 can be removed by removing the second shaft portion 37 at the other end of the L-shaped link 30 from the locking claw 35, the central panel 19 is cleaned and washed in an easy posture. be able to.
[0013]
As shown in FIGS. 4 and 6, when the central panel 19 is opened, the central panel 19 hangs downward with the second shaft portion 37 pivotally supported by the locking claw 35 as a support shaft. As shown in FIG. 8, the gap d between the central panel 19 and the decorative frame 22 can be set small by the action of the L-shaped link 30 when the central panel 19 is closed as shown in FIG. At the same time, the central panel 19 can be formed larger outside the position of the locking claw 35.
[0014]
Next, the first embodiment of the L-shaped link of the present invention shown in the cross-sectional view of the main part in FIG. 6, the cross-sectional view of the main part in FIG. 7 and the perspective view of the L-shaped link in FIG. .
Reference numeral 38 denotes left and right L-shaped portions of the L-shaped link 30, and 39 is a pressing convex portion that protrudes laterally from the second shaft portion 37 between at least the pair of left and right engaging claws 35.
The L-shaped link 30 includes the first shaft portion 31 that connects both ends of the left and right L-shaped portions 38 and the left and right L-shaped portions 38, and the second shaft portion including the pressing convex portion 39. 37 is formed by bending a steel wire, and both ends 40 of the steel wire are abutted at the approximate center of the first shaft portion 31.
[0015]
As shown in FIG. 6, after the central panel 19 is opened, the second shaft portion 37 is moved by pressing the pressing convex portion 39 of the L-shaped link 30 with a finger or the like in the direction of arrow F in the figure. It can be easily removed from the locking claw 35 over the locking projection 36, and the central panel 19 can be easily removed.
[0016]
The L-shaped link 30 includes the first shaft portion 31 that connects both ends of the left and right L-shaped portions 38 and the left and right L-shaped portions 38, and the second shaft portion including the pressing convex portion 39. 37 can be formed by bending a steel wire, so that only one type of parts is required and an inexpensive configuration can be achieved.
[0017]
By adopting a configuration in which both ends 40 of the steel wire are abutted at substantially the center of the first shaft portion 31, the U-shaped shaft support portion 28 of the corner portion reinforcing bracket 24 is placed on one side of the center panel 19. Since both ends 40 of the steel wire, which are likely to be structurally weak, can be disposed in a fixed and pivotally supported portion, the L-shaped link 30 is hardly deformed when the central panel 19 is opened and closed. be able to.
[0018]
Next, a second embodiment of the L-shaped link of the present invention shown in the perspective view of the L-shaped link of FIG. 9 will be described in detail.
Reference numeral 41 denotes a linear finger hook portion formed on the tip side of the pressing convex portion 39 protruding from the second shaft portion 37.
When the second shaft portion 37 is removed from the locking claw 35, a finger or the like can be hooked on the linear finger hooking portion 41, so that the pressing convex portion 39 can be easily pressed, and the second shaft The part 37 can be easily removed from the locking claw 35.
[0019]
【The invention's effect】
As described above, according to the present invention, the center panel can be supported by the L-shaped links having the rotation shafts at both ends, whereby the center panel can be configured to cover the entire lower portion, and the cleaning can be performed. For this reason, it becomes a ceiling-embedded air conditioner where the center panel can be easily removed.
