[Industrial applications]

  The present invention relates to an air conditioner, and more particularly, to a bell mouth of a ceiling-embedded air conditioner. Regarding holding structure.

[0002]

[Prior art]

  A ceiling-embedded air conditioner according to a conventional example has a lower portion opened with reference to FIG. 5 together with FIG. The fan 2 and the heat exchanger 3 surrounding the fan 2 are arranged in the box-shaped main body 1 and the heat exchange is performed. The open surface is covered with a shielding member 4 in contact with the lower surface of the container 3, and the fan 2 is attached to the shielding member 4. And a discharge port 6 between the main body 1 and the suction port 5. 5 is covered with a bell mouth 7, one end is fixed to the lower end of the main body 1, and the other end is supported by a support rod 8. While pressing the shielding member 4 against the heat exchanger 3 by the four held support plates 9, The bell mouth 7 is fixed to the support plate 9 from below by screws.

[0003]

[Problems to be solved by the device]

  However, when removing the bell mouth for maintenance, inspection, repair, etc., The bell mouth will drop the moment you remove the screw, and hold the bell mouth when installing it. Since it is necessary to screw it in, it is necessary for two people to work together. When you perform it with one hand, hold the bell mouth with one hand and remove or install the screw with the other hand. Since it is easy to lose the rabbit head screw, it takes extra time to search There was a drawback that the construction time was long and the construction cost was high.

[0004]

[Means for Solving the Problems]

  In order to solve the above-mentioned problems, in the present invention, the inside of a box-shaped main body whose lower part is opened A fan and a heat exchanger surrounding it are installed on the bottom of the heat exchanger. Is covered with a shielding member, and the shielding member is provided with an intake port facing the fan. An air conditioner that has a discharge port between the main unit and the suction port covered with a bell mouth. In addition, a plurality of support plates for holding the shielding member from below are provided, and the bell mau is attached to this. Locking means for fixing the belt and locking the peripheral portion of the bell mouth to one of the supporting plates. It is characterized by comprising.

[0005]

[Action]

  One end of the bell mouth is locked by the support plate and does not fall.

[0006]

【Example】

  Hereinafter, an embodiment of an air conditioner according to the present invention will be described with reference to FIGS. 1 to 4. 1 is a sectional view of the present air conditioner, FIG. 2 is a bottom view thereof, and FIG. 1 is a sectional view taken along line AA of FIG. It represents. As shown in the figure, the box-shaped main body 1 with the lower part opened has a The heat exchanger 3 is likewise hung down around it. Same heat exchange A shield member 4 which is in contact with the lower surface of the container 3 and also serves as a dew tray faces the fan 2 and has an intake port 5 A perforation is provided and a discharge port 6 is provided between the main body 1 and the main body 1 to cover the open surface. And this suck The entrance 5 is covered with a bell mouth 7. FIG. 3 is an enlarged bottom view of the main part, and FIG. 4 which is a BB arrow view of the above, the shielding member 4 has two screws at one end. Fixed to the main body 1 with the other end fixed to the main body 1 and provided at the lower end of the hanging support rod 8. Is pressed against the heat exchanger 3 from below by the four support plates 9 fixed to the screws with nuts. There is. One of the support plates 9 is provided with a locking portion that locks the peripheral portion of the bell mouth 7. Has been. That is, as shown in FIGS. 3 and 4, at the lower end of the inner peripheral vertical wall of the support plate 9. Is provided with a locking claw 9a that projects obliquely upward, and a base located above the locking claw 9a. A rectangular locking hole 7a is formed in the peripheral portion of the luma mouth 7. Also, it is clear from FIG. As can be seen, the suction port 5a near the support plate provided with the locking claw 9a of the locking means. The peripheral portion 7b of the bell mouth, which is provided with the locking hole 7a and the It

[0007]   Therefore, when mounting the bell mouth 7, as shown in FIG. b to the inlet port 5a of the irregular shape, and the bell mouth 7 as shown by the chain double-dashed line in FIG. The locking hole 7a of the bell plate 7 is locked to the locking claw 9a of the support plate 9 to prevent the falling, Are fixed to the support plate 9 with screws. On the contrary, when removing, it faces the support plate with locking means. If you remove the screws from the support plate last, you can use the bell when you remove the last screw. The mouse 7 is locked by the locking means and does not fall. Also, with the bell mouth 7 locked The service may be carried out while it is suspended.

[0008]

[Effect of device]

  Since the support plate and bell mouth are provided with locking means, pull out the last screw when removing Even if the bell mouth does not drop, you can perform services etc. with it locked. As a result, the work can be done easily by one person. And the suction port is modified so that the position of the locking means can be easily identified. Thus, it is possible to achieve the effect of reducing the working time.
