Description

Technical Field

[0001] The utility model relates to the technical field of diffusers, and in particular to a diffuser for preventing condensed water. Background Art

[0002] When the central air conditioner is in use, the temperature-regulated air is delivered into the room. The diffuser is an indoor air outlet of the air conditioner, usually installed on the ceiling. Common shapes are square or round. Its function is to make the air flow entering the room flow evenly and dispersedly.

[0003] Generally speaking, a diffuser is provided with multiple circles of blades inside, and a flow channel for airflow is formed between two adjacent circles of blades, guiding the airflow to disperse and flow in all directions.

DETAILED DESCRIPTION

[0032] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-7 As shown, the utility model provides a diffuser for avoiding condensation water, comprising a housing 1, wherein a plurality of blades 11 are arranged inside the housing 1, wherein the outer ends of the outermost blades 11 are in contact with the inner wall of the housing 1, and flanges 7 are fixedly arranged at the bottom ends of the other blades 11 except the two outermost blades 11;

[0034] A bottom plate 2 is fixedly provided at the bottom end of the housing 1, a baffle frame 3 is fixedly provided at the outer end of the bottom plate 2, a plurality of funnel-shaped grooves 4 are opened at the outer end of the baffle frame 3, and the outer opening area of ​​the funnel-shaped groove 4 is larger than the inner opening area;

[0035] By arranging a plurality of blades 11 inside the housing 1, a passage for air circulation is formed between two adjacent blades 11, and a horizontal flange 7 is arranged at the bottom end of the plurality of inner blades 11, so that the air in the middle part can flow horizontally after being blown out, so as to draw in the indoor air. However, since the flange 7 is not arranged at the bottom end of the two outer blades 11, the air outside will be blown out downwards and will not flow close to the ceiling. There is a certain space between the airflow and the ceiling to draw in the indoor air, so as to avoid the blown cold air from approaching the ceiling and the metal keel on the ceiling to generate condensed water, thereby avoiding the adverse effect of the condensed water on the ceiling and the metal keel.

[0036] At the same time, a baffle frame 3 is arranged on the outside of the bottom plate 2. The baffle frame 3 can effectively prevent the air blown out from the inside of the shell 1 from diffusing horizontally along the ceiling to avoid condensation on the ceiling. The funnel-shaped groove 4 on the baffle frame 3 has a small inner opening, and it is difficult for the air to flow from the inside to the outside. The outer opening is larger, and the external air is more likely to flow to the inside of the baffle frame 3, without affecting the suction of indoor air.

[0037] In order to directly observe the direction of airflow near the ceiling, Figure 2 , 5 As shown, a plurality of wind direction components 9 are provided at the bottom end of the base plate 2, and the wind direction components 9 include a storage tube 901 fixed at the bottom end of the base plate 2, and a plurality of streamers 903 are provided inside the storage tube 901, and the bottom end of the streamer 903 extends to the bottom of the storage tube 901, and the wind direction components 9 are located on the outside of the outer shell 1.

[0038] The wind direction assembly 9 also includes a fixed shaft 902 located inside the storage tube 901. Both ends of the fixed shaft 902 are arranged on the inner wall of the storage tube 901 through a rotating shaft. One end of the fixed shaft 902 extends to the outside of the storage tube 901 and is fixed with a handle.

[0039] The top end of the ribbon 903 is wound around the outer end of the fixed shaft 902 , and the bottom end of the storage tube 901 is provided with a plurality of notches corresponding to the ribbon 903 , and the bottom end of the ribbon 903 extends to the bottom of the storage tube 901 through the corresponding notches.

[0040] By turning the handle, the fixed shaft 902 is driven to rotate, and the length of the ribbon 903 at the bottom of the storage tube 901 is adjusted as needed to make it of appropriate length. The ribbon 903 is located on the outside of the opening at the bottom end of the shell 1 and close to the ceiling. If the airflow at the ceiling position is still flowing horizontally, the ribbon 903 will float in the horizontal direction. If the airflow is away from the ceiling, the ribbon 903 will float downward at an angle. The floating direction of the ribbon 903 is roughly the same as the airflow direction near the ceiling, so that the airflow direction at this position can be intuitively observed.

[0041] The air entering the room should be as clean and odor-free as possible. Figure 3 , 4 As shown, a cover plate 5 is provided at the top of the housing 1 by bolts, an air duct 6 is fixedly provided at the top of the cover plate 5, and a detachable filter 8 is provided at the bottom opening of the air duct 6 for filtering impurities in the air.

[0042] The housing 1 is provided with a threaded ring 16, which is fixed to the bottom end of the cover plate 5, and the bottom end of the threaded ring 16 is provided with a storage bottle 14 through a threaded sleeve;

[0043] The storage bottle 14 is filled with spices, and the spices can be selected from common fragrance essential oils in life. The outer end of the storage bottle 14 is provided with a plurality of air holes 15 for distributing fragrance, which plays a role in reducing peculiar smell in the air.

[0044] After the temperature of the air is adjusted by the air conditioner, it enters the housing 1 through the air duct 6 and is finally blown into the room. Before entering the housing 1, the air is first filtered by the filter 8. When passing through the inside of the housing 1, the fragrance in the storage bottle 14 will emit fragrance. The fragrance enters the housing 1 through the air vent 15 and is recalled and mixed with the air, and then blown into the room, making the indoor air fresher and avoiding odor in the room.

[0045] In order to facilitate the removal and cleaning of the blade 11, Figure 2 , 3 As shown in , 6 and 7, a fixing frame 10 is provided at the bottom end of the base plate 2 by bolts, a plurality of support plates 1001 are fixedly provided inside the fixing frame 10, and an elastic pad 1002 in contact with the bottom end of the flange 7 and the bottom ends of the two outermost blades 11 is fixedly provided at the top end of the support plate 1001.

[0046] A plurality of detachable fixing beams 12 are provided on the inner wall of the shell 1 , and the blades 11 are clamped between the fixing beams 12 and the elastic pads 1002 , so that each blade 11 is fixed inside the shell 1 .

[0047] A plurality of fixing beams 12 are fixedly provided on the inner wall of the outer shell 1, and a fixing frame 10 is provided on the baffle frame 3 at the bottom end of the outer shell 1, and a support plate 1001 and an elastic pad 1002 are provided on the fixing frame 10, and the blades 11 are fixed by clamping up and down. After removing the fixing frame 10, the blades 11 inside the outer shell 1 can be removed for easy cleaning, maintenance and replacement.

[0048] During use, the condensed water on the blades 11 and flanges 7 also needs to be cleaned. Figure 3 , 6 As shown, an external shaft 18 is provided inside the outer shell 1, and a sleeve 17 is provided at the outer end of the external shaft 18 through a bearing sleeve. One end of the fixed beam 12 is fixedly connected to the outer end of the sleeve 17, and a plurality of fan blades 13 fixed to the outer end of the external shaft 18 are provided on the top of the sleeve 17. The flowing air drives the fan blades 13 and drives the external shaft 18 to rotate.

[0049] The bottom end of the circumscribed shaft 18 extends to the bottom of the flange 7 and is provided with a detachable fixing plate 19. The top end of the fixing plate 19 is fixed with a sponge strip 20 that contacts the bottom end of the flange 7 and the bottom ends of the two outermost blades 11. The sponge strip 20 is soft in texture and can wipe and absorb condensed water.

[0050] When air flows through the outer shell 1, the fan blades 13 are driven to rotate and drive the external shaft 18. The external shaft 18 drives the fixed plate 19 and the sponge strip 20 to rotate at the bottom of the outer shell 1. During the rotation of the sponge strip 20, it rubs against the bottom end of the flange 7 and the two outermost blades 11, thereby wiping and absorbing the condensed water generated on its surface to prevent the condensed water from dripping.

[0051] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
