Description

Technical Field

[0001] The present invention relates to the technical field of ceiling fans, and particularly to a ceiling fan capable of purifying air.

Background Art

[0002] Currently, traditional ceiling fans only have the function of air circulation and cannot purify indoor pollutants. And independent air purifiers have problems such as occupying floor space and having a limited air flow circulation range. Therefore, in the prior art, there has emerged a combination of an air purifier and a ceiling fan, which solves the problems of the existing traditional air purifier occupying floor space and the ceiling fan only having the function of air circulation.

[0003] The traditional approach is generally to simply adjust the shape of the air purifier and then combine it with the ceiling fan. For example, a ceiling fan with an air sterilization and purification function disclosed in the patent application number "202220386332.8" directly sets the air purification mechanism at the bottom of the ceiling fan to purify the air. Its air inlet is located on the side, and after purification, it flows out from the bottom, which is similar to most practices in the market. However, the wind force is relatively low directly below the ceiling fan, and the purified air will be drawn back into the interior from the air inlet by the fan in the air purification mechanism, making it difficult to achieve circulation and resulting in an unsatisfactory air purification effect. Moreover, the air purification mechanism is stationary, and dust is likely to accumulate at the air inlet, making it inconvenient to clean.

Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a ceiling fan capable of purifying air. By setting an air purification mechanism at the bottom of the ceiling fan and setting the air inlet on the windward surface of the fan blades, the air intake can be increased, the problem of dust accumulation at the air inlet can be solved, and the air inlet can be far away from the air outlet, which can solve the problem that after the air is purified, it flows back into the air inlet again and it is difficult to circulate the purified air.

[0005] To solve the above technical problem, the present invention provides a ceiling fan capable of purifying air, including a ceiling fan body and an air purification mechanism provided at the bottom of the ceiling fan body;

[0006] The ceiling fan body includes an outer rotor motor, a plurality of fan blades and a hanging assembly. The outer rotor motor includes a rotor assembly and a stator assembly. One end of the hanging assembly is connected to the stator assembly, and the other end is connected to the ceiling. The plurality of fan blades are connected to the rotor assembly;

[0007] The air purification mechanism includes a purification chamber connected to the lower part of the stator assembly for purifying air. An air inlet communicating with the purification chamber is provided on the windward surface of the root of each fan blade. An air outlet for discharging the purified gas to below the fan blades so that the fan blades can disturb the discharged gas is formed at the bottom and / or the bottom side of the purification chamber.

[0008] A blower is further provided in the purification chamber to facilitate pumping the gas before purification into the purification chamber and discharging the purified gas.

[0009] For a ceiling fan capable of purifying air as described above, the included angle between the windward surface at the root of the fan blade and the horizontal plane is a, and it satisfies: 90° ≤ a < 180°.

[0010] For a ceiling fan capable of purifying air as described above, the purification chamber is composed of a chamber shell provided at the lower part of the stator assembly, a filter element provided in the chamber shell, and a chamber cover connected to the bottom of the chamber shell. The chamber shell and the chamber cover form a filtration chamber. A plurality of through holes communicating the air inlet and the filtration chamber are formed around the chamber shell. The filter element is cylindrical and vertically arranged in the filtration chamber. The air outlet is provided on the chamber cover, and the blower is provided in the middle of the filter element and connected to the top of the filtration chamber.

[0011] For a ceiling fan capable of purifying air as described above, a limiting portion that is hermetically fitted with the bottom of the filter element extends inwards from the upper part of the edge of the chamber cover.

[0012] For a ceiling fan capable of purifying air as described above, a dust-proof net is detachably provided at the air inlet.

[0013] For a ceiling fan capable of purifying air as described above, a first sterilization chamber is formed between the filter element and the chamber shell, and a first sterilization component is provided in the first sterilization chamber.

[0014] For a ceiling fan capable of purifying air as described above, a second sterilization chamber is formed in the middle of the filter element, and a second sterilization component is provided in the second sterilization chamber.

[0015] For a ceiling fan capable of purifying air as described above, the bottom side of the chamber cover extends to the bottom of the root of the fan blade.

[0016] For a ceiling fan capable of purifying air as described above, the air outlet gradually decreases from inside to outside and is inclined towards the lower area of the fan blade.

[0017] For a ceiling fan capable of purifying air as described above, the filter element includes at least one of a negative ion dust removal filter screen, an aldehyde removal filter screen, and a deodorant filter screen.

[0018] Compared with the prior art, the ceiling fan capable of purifying air according to the present invention has the following advantages:

[0019] 1. The present invention sets the air inlet on the windward side of the fan blade, and the fan blade rotates to fill the air into the purification chamber, thereby increasing the air intake. The fan in the air evolution mechanism is then used to extract air, and the unpurified air can be quickly drawn into the purification chamber for purification, thereby improving the purification efficiency. Setting the air inlet on the fan blade can increase the air intake, and a low-power fan can also achieve an excellent air extraction effect, thereby saving costs.

[0020] 2. The present application can reduce dust accumulation by setting the air inlet on the windward side of the fan blade, thereby reducing the cleaning frequency and facilitating maintenance.

[0021] 3. The air inlet of the present application is far away from the air outlet, which will not cause the problem of the air flowing back to the air inlet after purification, and the purified air can be circulated throughout the house.

Detailed implementation manners

[0040] The following will describe the implementation manners of the present invention in detail with reference to the accompanying drawings.

[0041] As Figures 1-11 shown, the present invention includes a ceiling fan capable of purifying air, including a ceiling fan body 1 and an air purification mechanism 2 provided at the bottom of the ceiling fan body 1. The ceiling fan body 1 includes an outer rotor motor 10, several fan blades 3 and a hanging assembly 4. The outer rotor motor 10 includes a rotor assembly 11 and a stator assembly 12. One end of the hanging assembly 4 is connected to the stator assembly 12, and the other end is connected to the ceiling. Several fan blades 3 are connected to the rotor assembly 11. The hanging assembly 4 includes a hanger 40 connected to the ceiling and a suspension rod 41 for connecting the hanger 40 and the stator assembly 12, and further includes an upper cup 42 connected to the hanger 40 for covering the hanger 40. The air purification mechanism 2 includes a purification chamber 20 connected to the lower part of the stator assembly 12 for purifying air. An air inlet 30 communicating with the purification chamber 20 is provided on the windward surface of the root of each fan blade 3. An air outlet 21 for discharging the purified gas to below the fan blade 3 so that the fan blade 3 can disturb the discharged gas is formed at the bottom and / or the bottom side of the purification chamber 20. In this application, preferably, the air outlet 21 is arranged on the bottom side of the purification chamber 20.

[0042] A fan 22 is further provided in the purification chamber 20 for facilitating the suction of the gas before purification into the purification chamber 20 and the discharge of the purified gas.

[0043] In this application, the air purification mechanism 2 is combined with a ceiling fan, and the air inlet 30 of the purification chamber 20 is arranged on the windward surface of the root of the fan blade 3. When the ceiling fan is started, air is poured into the purification chamber 20 from the air inlet 30 for purification. Combined with the use of the fan 22, the gas can be further drawn into the purification chamber 20 for purification, increasing the air intake. And through the fan, the purified gas can be blown outwards to the lower part of the fan blade 3, and the ceiling fan disturbs the purified air to realize the whole-room circulation and improve the purification efficiency.

[0044] Since the fan blade 3 is always rotating, the air inlet 30 is not likely to accumulate dust, and the air inlet 30 is far from the air outlet 21, which will not cause the problem that the air flows back to the air inlet 30 after being purified.

[0045] Moreover, after the fan 22 is provided, the air can be purified even when the ceiling fan is not started, which is more in line with the usage situation of consumers.

[0046] In addition, the air inlet 30 is arranged on the windward surface of the fan blade 3, and the front of the fan blade 3 generally faces the ground so that air supply can be realized when the fan blade 3 rotates. In this way, it is not easy for dust to accumulate at the air inlet 30.

[0047] Such as Figure 11 As shown, as a further solution of this embodiment, the included angle between the windward surface at the root of the fan blade 3 and the horizontal plane is a, then: 90° ≤ a < 180°. In this application, the included angle a between the windward surface at the root and the horizontal plane is set to be greater than or equal to 90° and less than 180°, so that dust will not settle at the air inlet 30, and the cleaning frequency can be reduced.

[0048] Such as Figures 6 to 11As shown in the figure, as a further solution of this embodiment, the purification chamber 20 is composed of a chamber shell 23 provided at the lower part of the stator assembly 12, a filter element 24 provided in the chamber shell 23, and a chamber cover 25 connected to the bottom of the chamber shell 23. The chamber shell 23 and the chamber cover 25 form a filtration chamber 26. A plurality of through holes 27 communicating the air inlet 30 and the filtration chamber 26 are formed around the chamber shell 23. The filter element 24 is cylindrical and vertically arranged in the filtration chamber 26. The air outlet 21 is provided on the chamber cover 25. The fan 22 is provided in the middle of the filter element 24 and is connected to the top of the filtration chamber 26. Among them, the filter element 24 includes at least one of a negative ion dust removal filter screen 240, a formaldehyde removal filter screen 241, and a deodorant filter screen 242. In this embodiment, the filter element 24 is composed of a negative ion dust removal filter screen 240, a formaldehyde removal filter screen 241, and a deodorant filter screen 242 arranged in sequence from outside to inside, so that the functions of dust removal, formaldehyde removal, and deodorization can be realized. It should be noted that the through holes 27 are communicated with the air inlet 30 of the fan blade 3. When the fan blade 3 is started, air flows from the air inlet 30 to the through holes 27 and then enters the filtration chamber 26. Because air continuously pours in from the air inlet 30, the pressure at the through holes 27 is greater than the pressure in the filtration chamber 26. Therefore, without starting the fan 22, the gas can also flow into the filtration chamber 26 for filtration and discharge the filtered gas.

[0049] As Figure 8 , Figure 9 shown, as a further solution of this embodiment, a limiting portion 250 that is hermetically fitted with the bottom of the filter element 24 extends inward from the upper part of the edge of the chamber cover 25. By providing the limiting portion 250 to cooperate with the bottom of the filter element 24, the filter element 24 does not directly cooperate with the bottom of the chamber cover 25, and the purified air can diffuse outward, facilitating the fan blade 3 to disturb the purified air. Further, the bottom side of the chamber cover 25 extends to the bottom of the blade root of the fan blade 3. This can prevent the purified air from flowing back into the channel through the gap between the chamber cover 25 and the fan blade 3, and can also play a certain role in obstructing the air, preventing the air entering from the air inlet 30 from quickly flowing away through the gap between the fan blade 3 and the chamber cover 25. In order to make the sealing effect better, the connection between the blade roots of adjacent fan blades 3 can also be set to be tightly connected.

[0050] In this embodiment, in order to facilitate the replacement and installation of the filter element 24, the chamber cover 25 and the chamber shell 23 are connected by a threaded connection. And because the filter element 24 is cylindrical, during installation, the filter element 24 is directly placed on the limiting portion 250 of the chamber cover 25, and then it can be rotated to align with the chamber shell 23 to complete the installation. In order to enhance the sealing performance, sealing rings can be provided at the upper and lower ends of the filter element 24. The sealing rings are not shown in this application. After the chamber cover 25 is fixed, the upper and lower ends of the filter element 24 can be hermetically connected to the limiting portion 250 and the inner top of the chamber shell 23 through the sealing rings.

[0051] In addition, in order to make the flow rate of the purified gas when flowing out of the air outlet 21 faster and make the purified gas be disturbed by the fan blades 3, the air outlet 21 is set to gradually decrease from inside to outside, and the air outlet 21 is inclined towards the lower area of the fan blades 3. In this way, the purified air can be blown to the lower part of the middle section of the fan blades 3, enabling the purified air to circulate quickly.

[0052] As Figure 3 shown, as a further solution of this embodiment, a dust-proof net 31 is detachably provided at the air inlet 30. By providing the dust-proof net 31, most of the dust can be pre-filtered, and mosquitoes and flies can also be prevented from entering the air inlet 30.

[0053] As Figure 6 、 Figure 7 shown, as a further solution of this embodiment, a first sterilization chamber 5 is formed between the filter element 24 and the cavity shell 23, and a first sterilization component 50 is provided in the first sterilization chamber 5. A second sterilization chamber 51 is formed in the middle of the filter element 24, and a second sterilization component 52 is provided in the second sterilization chamber 51. In this embodiment, by providing the first sterilization component 50, the air before purification can be sterilized, preventing bacteria from remaining in the filter element 24. And a second sterilization chamber 51 is formed in the middle of the filter element 24, and the second sterilization component 52 is used for re-sterilization, further improving the sterilization effect. It should be noted that the first sterilization component 50 and the second sterilization component 52 can be ultraviolet lamps or ozone sterilization can also be used.
