[0005]   Therefore, the purpose of the present invention is to reduce the number of parts and the number of assembly steps, and The purpose is to provide a ceiling cassette type air conditioner that can achieve high efficiency.

[0006]

[Means for Solving the Problems]

  In order to achieve the above-mentioned object, the present invention is to house the air conditioner main body in the ceiling, Place the drain pump on the drain pan that receives the drain water generated in the heat exchanger in the body. In the ceiling cassette type air conditioner, the suction port of the drain pump is surrounded. The drain filter and drain plug are integrally formed and attached to the drain pan. Is characterized by.

[0007]

[Action]

  Since the drain filter and drain plug are integrally formed, the number of parts and assembly work The number can be reduced and the cost can be reduced.

[0008]

【Example】

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0009]   1 and 2 showing a first embodiment of the present invention, 1 is an air conditioner in a ceiling 2. This is a ceiling cassette type air conditioner in which the Japanese machine main body 3 is stored and installed. The body 3 has a casing 4 whose lower part is open, in which a motor 5 Sirocco fan 6, which blows air upward from below by driving The heat exchangers 7 and the like located on both sides of the fan 6 are arranged.

[0010]   The lower part of the inside of the casing 4 is covered with a heat insulating material and the central part is an air intake port. A drain tray 9 is provided which is opened as 8 and receives drain water generated in the heat exchanger 7. In the lower part of the casing 4, a suction grill 10 that covers the suction port 8 is detachably attached, Moreover, the ceiling panel 12 on which the blowout louver 11 is formed is attached.

[0011]   Then, the drain pump 13 is arranged on the drain tray 9, and the drain tray 9 is As shown in FIG. 3, the drain filter 1 surrounding the suction port 13a of the drain pump 13 4 is attached in a state of being integrally formed with the drain plug 15. Drain filter 14 has a cylindrical shape with a bottom, and a cylindrical drain plug 15 is in communication with the center of the bottom. Are integrally formed with. A large number of small holes 14a are formed on the side wall of the drain filter 14. And a plurality of openings 14b are formed in the bottom as shown in FIG. this The drain filter 14 is a drain plate with the drain plug 15 penetrating the drain plate 9. It is mounted on the upper surface of the plate 9 and fixed by filling the opening 14b with an adhesive. The rubber plug 16 is attached to the drain plug 15 protruding from the bottom of the drain tray 9 from the outside. Is inserted.

[0012]   According to the ceiling cassette type air conditioner 1 configured as described above, the drain filter 14 and the drain plug 15 are integrally formed, the number of parts and the number of assembling steps Can be reduced and cost can be reduced.

[0013]   5 to 7 show a second embodiment of the present invention. Ceiling cassette in this embodiment In the cot type air conditioner 1, the portion 17 of the drain tray 9 where the drain pump 13 is located is This split part 17 is detachably attached to the drain tray 9 from the lower surface. It has been burned.

[0014]   More specifically, the drain pump 13 is mounted on the ceiling of the casing 4. It is attached to the mounting base 18 with screws 19. The drain plate 9 has a drain pump 13 An opening 20 that is located directly below and larger than the drain pump 13 is formed. A step portion 21 having an enlarged diameter is formed on the outer peripheral edge of the opening 20. The dividing unit 1 7 is formed in a shape that engages with the opening 20, and the split portion 17 has a substantially central portion. A drain plug 15 is provided. It should be noted that the dividing unit 17 is provided with the first embodiment. In, the drain filter 14 integrally formed with the drain plug 15 may be mounted. .

[0015]   In order to attach the dividing portion 17 to the drain pan 9 with the screw 22, the peripheral edge of the dividing portion 17 A screw hole 23 is formed in the portion, and the screw 22 is screwed into the step portion 21 of the drain tray 9. The insert metal fitting 24 is attached. In addition, in the step portion 21 of the dividing portion 17, A packing 25 for sealing is attached to the opposite mounting surface.

[0016]   According to the above configuration, when performing maintenance of the drain pump 13, the ceiling panel If the suction grill 10 of 12 is removed and the split portion 17 of the drain tray 9 is removed, The pump 13 can be easily removed from the mount 18 for maintenance. Since it is not necessary to remove the ceiling panel 12 and the entire drain tray 9, workability is improved. The time required for maintenance can be greatly reduced.

[0017]

[Effect of device]

  In summary, according to the present invention, the drain filter and the drain plug are integrally formed. Therefore, the number of parts and the number of assembling steps are reduced, and the cost can be reduced.
