Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

Referring to fig. 1-5, the present invention provides a ceiling-mounted blower 100, comprising: the device comprises a shell 1, a volute fan 2, an access panel 3, a pressure plate screw 4, a pressure plate 5, a spring 6 and an air deflector 7.

The shell 1 is provided with an access hole 11, an air inlet 12 and an air outlet 13. In this embodiment, the housing 1 is a rectangular parallelepiped structure, and the air inlet 12 and the air outlet 13 are respectively opened at two opposite sides of the housing 1 and are communicated with the inside of the housing 1. The access opening 11 is opened at the other side of the housing 1.

The volute blower 2 is mounted inside the housing 11. The axial direction of the air inlet end of the volute fan 2 is perpendicular to the air inlet direction of the air inlet 12, and the air outlet end of the volute fan 2 is communicated with the air outlet 13. The side surface of the shell corresponding to the air inlet end of the volute fan 2 is not the same as the side surface of the shell provided with the access hole 11.

For example, the access opening 11 is disposed on the left side or the right side of the casing 1, the air inlet 12 and the air outlet 13 are disposed on the front side and the rear side of the casing 1, respectively, and the air inlet end of the volute blower 2 is opposite to the upper side and/or the lower side of the casing 1.

In this embodiment, preferably, the volute blower 2 is a volute blower with a double air inlet channel structure, i.e. the two opposite sides of the volute blower are respectively provided with one air inlet end.

The access panel 3 covers the shell 1 and completely covers the access opening 11.

The pressing plate screws 4 comprise a plurality of screws which are respectively fixed on the outer side of the shell 1 and surround the access hole 11, and the pressing plate screws are located on the outer side of the access plate 3.

In this embodiment, clamp plate screw 4 include four and equally divide set up in the relative both sides of access panel 3 are located access panel 3 is with two of one side clamp plate screw 4 is the interval each other. Of course, the number is not limited to this, and generally, after the two-way valve is arranged, the fixing stability is reasonable, and the opening or closing efficiency is fast.

The pressing plate 5 is matched with the pressing plate screws 4, and one end of each pressing plate 5 is sleeved on one pressing plate screw 4 and is in rotating connection with the pressing plate screw 4. That is, the pressing plate 5 is sleeved on the pressing plate screw 4, penetrates through the pressing plate 5 through the screw rod part of the pressing plate screw 4, and is limited to the pressing plate 5 by the screw head part of the pressing plate screw 4.

The pressing plate 5 is rotated to enable the free end of the pressing plate 5 to be positioned outside the pressing plate 5, and the pressing plate 5 can be abutted against the maintenance plate 3 and limited and locked by rotating and screwing the pressing plate screw 4; can make clamp plate 5 leave access panel 3 in order to cancel the spacing locking to access panel 3 through rotating unscrew clamp plate screw 4, at this moment, rotate clamp plate 5's free end outside being located 5 scopes of clamp plate, then can remove clamp plate 5, and clamp plate screw 4 and clamp plate 5 all need not follow casing 1 and pull down, and then realize quick convenient opening or close access panel 3, the effectual maintenance convenience that has improved.

One end of the spring 6 is fixed on the shell 1 and is positioned on the periphery of the access opening 11, and the other end of the spring 6 is abutted against the access panel 3. When making clamp plate 5 leave from access panel 3 in order to cancel the spacing locking to access panel 3 through rotating unscrewing clamp plate screw 4, access panel 3 is backed up to spring 6 because of the elastic restoring force that is recovered its compression deformation production by access panel 3 compression, further more convenient the opening access panel of rapider.

In this embodiment, the springs 6 include two springs and are disposed at an interval on the same side of the access opening 11. Only need set up spring 6 in one side of access hole promptly, with one of them side auto-eject of access panel 3, can conveniently open.

Preferably, in the present embodiment, one side of the casing 1 provided with the access opening 11 is recessed to form a yielding groove 8, and the size of the yielding groove 8 is matched with the access panel 3. The access hole 11 runs through the groove 8 that steps down sets up, spring 6 is located step down the inslot 8, access panel 3 accept in step down the inslot 8 and will spring 6 compresses, clamp plate screw 4 is located step down outside the groove 8, through rotating clamp plate screw 4 makes clamp plate 5 butt in the outside of access panel 3 or with access panel 3 separation. The setting up of groove 8 of stepping down provides guide structure when installing for access panel 3 on the one hand, further improves maintenance efficiency, and on the other hand provides accommodating space for access panel 3 for the whole outward appearance uniformity of hoist and mount formula forced draught blower is better.

The air deflector 7 is fixed on one side, close to the air inlet 12, of the volute fan 2, so that the air entering the air inlet 12 can be directly guided to the air inlet end of the volute fan 2 through the air deflector 7, and the phenomenon that the entering air generates large wind resistance through the structural edge angle of the outer side of the volute fan 2 is avoided, and therefore the air pressure influences the air outlet effect and generates wind noise and influences the user experience effect is reduced.

Specifically, the air deflector 7 includes a first plate 71 facing the air inlet 12 and spaced apart from the volute blower 2, and two second plates 72 extending from two opposite sides of the first plate 71 to two sides adjacent to the inlet end of the volute blower 2 and fixed to the volute blower 2. More preferably, first board 71 is the arc structure, second board 72 is dull and stereotyped structure, first board 71 with second board 72 is smooth transition, further strengthens aviation baffle 7's water conservancy diversion effect, and then the air inlet wind pressure and the silence effect of effectual assurance.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
