Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a wind-hole base of a blower for an air conditioner, particularly to one possible to be combined quickly with a ceiling, having two outlets and an inlet so as to facilitate check and repair the wind-hole base when necessary.

[0003] 2. Description of the Prior Art

[0004] A conventional wind-hole base 8 for a central air conditioner shown in FIGS. 1 and 2, uses windpipes 81 connected to a main machine to circulate cool air and retrieve hot wind back. And an outlet 82 or an inlet 83 is provided at an end exit of each windpipe 81, performing air circulation to every room at the same time. Each room may have a steel frame 6 fixed on the ceiling for mounting the outlet 82 and the inlet 83 thereon. So the more the outlets 82 and the inlets are provided, the more the steel frames 6 have to be provided, complicating constructing processes and subsequent difficulty involved in maintenance and repair after they are finished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] A preferred embodiment of a wind-hole base of a blower for an air conditioner in the present invention, as shown in FIGS. 3, 4 and 5, includes a faceplate 1, a cover plate 2, two fix plates 3, and two wind outlet cases 4 as main components combined together.

[0015] The faceplate 1 has an outlet 10 provided respectively in two lengthwise opposite sides, wind guiding leaves adjustably fitted inside each outlet 10, plural combine holes 100 bored in a lengthwise wall, an inlet 11 formed in an intermediate portion, plural insert grooves 110 (FIG. 4 also referred) and engage holes 111 formed at diverse positions in an inner wall defining the inlet 11, link holes 112 of different shapes (such as rectangular, circular, etc.) provided in a circumferential edge of the inlet 11, a lengthwise grid plate 12 fixed to close on the inlet 11, and a filter net 13 positioned between the inlet opening 11 and the grid plate 12. The grid plate 12 has insert projections 120 extending outward from a lengthwise side, and so does the filter net 13 have insert projections 130, as shown in FIGS. 3 and 5. Further, an elongate connector 14 is respectively fixed on two lengthwise opposite sides of the faceplate with screws 7, having a threaded rod 140 extending upward.

[0016] The cover plate 2 is combined on the inlet 11 of the faceplate 1, shaped as an inverted case, having circumferential lip edges 20 to fit closely in an inner circumferential edge of the inlet 11 of the faceplate 1, plural insert projections 21 extending out from a lengthwise side to fit in the insert grooves 110 of the inlet opening 11, plural engage blocks 22 formed to extend down from the other lengthwise side and plural posts 23 each with a center screw hole formed downward near the relative engage blocks 22 to fit in the link holes 112 of the inlet 11 or screwed together with the faceplate 1 with screws 7. Besides, the cover plate 2 has plural outlet holes 24 spaced apart for connecting windpipes 5.

[0017] The two elongate fix plates 3 are fixed across on the steel frame 6 mounted on the ceiling, combined with the connectors 14 of the faceplate 1, having an elongate slot 30 respectively in two end portions for the threaded rod 140 to pass through to adjust their own position, fixed with screws 31 in place, and in addition, the screws 31 can adjust the gap between the faceplate 1 and the steel frame 6 as well.

[0018] The two wind outlet cases 4 are fixed respectively to close up on the two outlets 10 of the faceplate 1 by means of screws 7, having a surrounding wall of a certain thickness and height and made of heat insulating material (for example, foam) to keep inner temperature, a rectangular opening 41 formed in a bottom side, plural combine holes 42 bored in the wall around the opening 41 and screwed with the combine holes 100 of each outlet 10. Further, a circular outlet hole 43 is formed in an intermediate portion of each wind outlet case 4, and a connect member 44 is provided to combine with the wall around the outlet hole 43 for easily connecting with a wind pipe 5, having a fix plate 440 bored with plural screw holes 441 at an inner side so as to fix the connect member 44 with the wind outlet case 4 with screws 7. Further, the connect base 44 has many elastic plates 442 formed in an outer end of the two sides, and each elastic plate 442 has a projecting insert edge 443 to connect with the wind pipe 5 easily.

[0019] In assembling, referring to FIGS. 3-6, firstly fix the cover plate 2 in the inlet 11 of the faceplate 1, with the insert blocks 21 inserting in the insert grooves 110 of the faceplate 1, and with the engage blocks 22 inserting in the link holes 112 of the inlet opening 11 as shown in FIG. 5. Or the posts 23 with a center screw hole are made to pass through the link holes 112 and then screwed from under with screws 7 to fix the cover 2 with the faceplate 1. Next, the grid plate 12 and the filter net 13 are combined firmly under the inlet II with the insert projections 120 and 130 fitting in the insert grooves 110 and engage holes 111. Then the wind outlet cases 4 are screwed on the outlets 10 of the faceplate 1. When the wind-hole base is to be mounted on a ceiling, the two elongate plates 3 are placed across the steel frame 6, as shown in FIGS. 3 and 4, and then the threaded rods 140 of the connector 14 are made to pass through the elongate slots 30, and fixed firmly with the screws 31. Next, the wind pipes 5 are connected to the connect member 44 of the wind outlet cases 4 and the outlet holes 20 of the cover plate 2, finishing assembly of the wind-hole base either for sending wind out or sucking wind in, as shown in FIGS. 5 and 6.

[0020] Provided the wind-hole base or the wind pipes have to be checked or repaired, first remove the grid plate 12 and the filter net 13, and push open the cover 2 by pricking the engage blocks 22 off the insert grooves 110 or loosen the screws off the post 23. Now a worker can go through the inlet 12 in the wind-hole base for check or repair. Or a worker can adjust the location of the connectors 14 connecting the elongate fix plates 3 and the faceplate 1. Thus, maintenance or repair can be carried out easily.

[0021] The invention has the following advantages as can be understood from the aforesaid description.

[0022] 1. Its assembly can be performed quickly and easily

[0023] 2. It has a structure of both wind sending-out and sucking-in.

[0024] 3. Its maintenance or repair may be carried out with convenience.

[0025] 4. The faceplate can be adjusted vertically in the gap against the ceiling (or the steel frame) and also moved laterally by means of the connector and the fix frame with screws to alter its location if necessary.

[0026] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
