Description

Technical Field

[0001] The utility model relates to the field of air purifiers, in particular to an air outlet structure and an air purifier. Background Art

[0002] As human pollution to the environment becomes more and more serious and air quality becomes worse and worse, air purifiers have gradually become popular. Traditional air purifiers have limited air supply distance and cannot deliver clean air to a long distance, resulting in a slow air purification speed in the entire room.

[0003] In order to solve this problem, in the related art, there is an air purifier with a fan function, which includes a fan and a filter element. When in use, the fan drives the external air into the air purifier, passes through the filter element to be purified into clean air, and then blows out of the air purifier, thereby generating a purified airflow. In this way, the air purifier can send clean air to a longer distance through the fan, thereby increasing the air purification speed. However, the air purifier has only one fan, and the air output of a single fan is small, which is difficult to meet the user's demand for large air volume. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides an air outlet structure of an air purifier, which is used to solve the problem of how to increase the air outlet volume.

[0032] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the air outlet structure and the air purifier in the embodiment. Figure 2 : is a longitudinal cross-sectional view of an air outlet structure and an air purifier in an embodiment, wherein the air outlet structure comprises a purification module 1 , a fan module 2 and a casing 3 .

[0033] The housing 3 has a first air outlet 31 and a second air outlet 32 ​​on the same side.

[0034] The purification module 1 is installed in the housing 3, and the purification module 1 includes a first wind wheel 11 and a first driving member 12. The first driving member 12 is connected to the first wind wheel 11, and the first driving member 12 drives the first wind wheel 11 to rotate, so that the first wind wheel 11 generates a purified airflow flowing toward the first air outlet 31.

[0035] The fan module 2 is installed in the housing 3, and the fan module 2 includes a second wind wheel 21 and a second driving member 22. The second driving member 22 is connected to the second wind wheel 21, and the second driving member 22 drives the second wind wheel 21 to rotate, so that the second wind wheel 21 generates a fan airflow flowing toward the second air outlet 32. The second wind wheel 21 and the first wind wheel 11 have the same rotation direction, and the purified airflow and the fan airflow have the same outflow direction.

[0036] When the air outlet structure of the above technical solution is used on an air purifier, starting the first driving member 12 can drive the first wind wheel 11 to rotate. The rotation of the first wind wheel 11 drives the air to flow and blow out toward the first air outlet 31 after purification, thereby forming a purified airflow, thereby realizing the air purification function; and starting the second driving member 22 can drive the second wind wheel 21 to rotate. The rotation of the second wind wheel 21 drives the air to flow and blow out toward the second air outlet 32, thereby forming a fan airflow, thereby realizing the fan function. The fan airflow can bring the purified airflow to a farther place, thereby expanding the air purification range and improving the purification efficiency. Among them, the purification module 1 and the fan module 2 can be started to blow air separately, and can also be started to blow air at the same time. The damage of one of the fans does not affect the use of the other fan, and when the purification module 1 and the fan module 2 are started at the same time, the first wind wheel 11 and the second wind wheel 21 have the same direction, and the first air outlet 31 and the second air outlet 32 ​​are located on the same side (that is, the air outlet directions are consistent), so that the outflow directions of the purified airflow and the fan airflow are the same. In this way, the air outlets of the purification module 1 and the fan module 2 can be superimposed on each other, effectively increasing the air outlet of the air purifier, and effectively avoiding the air outlet irregularities and abnormal noises caused by the collision of the two airflows.

[0037] The first driving member 12 and the second driving member 22 may both use existing rotation driving devices such as motors, and the second wind wheel 21 may use an existing crossflow wind wheel.

[0038] See also Figure 1 As shown, in one embodiment of the casing 3, the casing 3 has an air outlet surface 33 and a ventilation duct 34 for connecting the purification module 1 and the fan module 2, the first air outlet 31 is opened on the air outlet surface 33, the air outlet surface 33 is inclined from bottom to top and extends toward the inside of the casing 3, and the air outlet surface 33 is located between the first wind wheel 11 and the ventilation duct 34. In this way, the air outlet surface 33 is located on the path of the purified air flow flowing from the first wind wheel 11 toward the ventilation duct 34, so that most of the purified air flow can flow out directly from the first air outlet 31, greatly shortening the path of the purified air flow flowing out of the air purifier, thereby reducing air flow loss and increasing the air outlet of the purification module 1, and a small part of the purified air flow can continue to flow upward from the ventilation duct 34 into the fan module 2, and driven by the fan airflow to flow out toward the second air outlet 32; wherein, the air outlet surface 33 can also guide the purified air flow to flow out of the first air outlet 31 obliquely upward so as to merge with the fan airflow flowing out of the second air outlet 32, and the ventilation duct 34 can facilitate the mixing of the fan airflow and the purified airflow, both of which are conducive to the fan airflow to bring the purified air to a farther place, thereby improving the purification effect, and both can further avoid the uneven air outlet and abnormal noise caused by the collision of the two airflows.

[0039] See also Figure 2 and Figure 3 As shown, Figure 3 It is a transverse cross-sectional view of the air outlet structure and the air purifier in the embodiment. On the basis of the above embodiment, an air inlet grille 35 and an air outlet grille 36 are installed on the casing 3 by screwing or integral connection, and the opening of the air outlet grille 36 is configured as a second air outlet 32. The air inlet grille 35 and the air outlet grille 36 are relatively distributed on both sides of the second wind wheel 21, and the air inlet grille 35 and the air outlet grille 36 are both connected to the fan module 2. In this way, since the flow path of air flowing from the purification module 1 to the fan module 2 is long, the air flow loss is large. If the air for generating the fan airflow is only supplied to the fan module 2 through the ventilation duct 34, the wind force of the fan module 2 may be insufficient, especially when the purification module 1 is turned off and the fan function is realized alone. It is difficult for a large amount of external air to enter the ventilation duct 34 from the purification module 1 and then enter the fan module 2. Therefore, an air inlet grille 35 is added to the fan module 2. The rotation of the second wind wheel 21 can drive the external air to enter the fan module 2 directly from the air inlet grille 35, rather than only from the ventilation duct 34. This greatly shortens the path for the air to enter the fan module 2 and reduces the air flow loss, so that the fan module 2 can output a large air volume and realize the fan function.

[0040] The ventilation duct 34 is located outside the second wind wheel 21, and the central axis of the second wind wheel 21 can deviate from the central axis of the first wind wheel 11, and the distance between the central axis of the second wind wheel 21 and the air outlet grid 36 can be smaller than the distance between the central axis of the second wind wheel 21 and the air inlet grid 35. In this way, the purified airflow spirally flows upward from the ventilation duct 34 into the fan module 2, and can also assist the eccentrically distributed second wind wheel 21 and the first wind wheel 11 to rotate in the same direction.

[0041] See also Figure 2 and Figure 3 As shown, on the basis that the external air can enter the fan module 2 through the air inlet grille 35, two guide plates 38 are installed in the housing 3 by means of integral connection or screw connection, and an air inlet channel 39 is formed between the two guide plates 38. The air inlet channel 39 is located between the air inlet grille 35 and the second wind wheel 21, and is used to guide the external air to flow from the air inlet grille 35 toward the second wind wheel 21. And the air inlet direction of the air inlet channel 39 is inclined with the radial direction of the second wind wheel 21. In this way, the air inlet channel 39 can limit the air inlet flow direction of the external air entering the fan module 2 from the air inlet grille 35 to be the same as the fan airflow direction generated inside the fan module 2, so that the two can be merged and blown out together, and can also avoid abnormal noise caused by airflow collision.

[0042] See also Figure 2 , Figure 3 and Figure 4 As shown, Figure 4: is a stereoscopic diagram of the first wind wheel in the embodiment. In one embodiment of the first wind wheel 11 and the second wind wheel 21, the first wind wheel 11 includes at least two first blades 111, each of the first blades 111 is spaced apart around the central axis of the first wind wheel 11, a first air passage 112 is formed between two adjacent first blades 111, and the first air passage 112 is connected to the first air outlet 31. The second wind wheel 21 includes at least two second blades 211, each of the second blades 211 is spaced apart around the central axis of the second wind wheel 21, a second air passage 212 is formed between two adjacent second blades 211, and the second air passage 212 is connected to the second air outlet 32. Among them, the first blades 111 and the second blades 211 are both in an arc-shaped structure, the first blades 111 are bent and extended from the outside of the first wind wheel 11 to the inside in the direction of rotation of the first wind wheel 11, and the second blades 211 are bent and extended from the inside of the second wind wheel 21 to the outside in the direction of rotation of the second wind wheel 21. In this way, when the first wind wheel 11 and the second wind wheel 21 rotate in the same direction, the first wind wheel 11 drives the air to spiral upward into the first wind wheel 11 along the direction of rotation, and then flows out from the first air duct 112 toward the first air outlet 31 to form a purified airflow, and the second wind wheel 21 drives the air to enter the second wind wheel 21 from the second air duct 212 on one side of the second wind wheel 21, and then passes through the second wind wheel 21 from the second air duct 212 on the other side of the second wind wheel 21 along the direction of rotation, and flows out toward the second air outlet 32 ​​to form a fan airflow, wherein the first fan blades 111 and the second fan blades 211 can facilitate the airflow to flow on the arc surface along the same direction of rotation through their own arc-shaped structures, thereby reducing the noise and air flow loss when the first wind wheel 11 and the second wind wheel 21 rotate, which is beneficial to increasing the air supply volume of the first wind wheel 11 and the second wind wheel 21, and is beneficial to improving the energy efficiency of the purification module 1 and the fan module 2.

[0043] See also Figure 2 and Figure 4As shown, on the basis of the above embodiment, the first wind wheel 11 also includes a bottom plate 113 and a cover plate 114, the middle part of the bottom plate 113 has an air outlet 115, each first blade 111 is fixed between the bottom plate 113 and the cover plate 114 by welding or integral connection, and each first blade 111 is located directly above the air outlet 115, the bottom surface of the cover plate 114 is arched downward and is arc-shaped to guide the purified airflow in the first air duct 112 to flow upward along the bottom surface of the cover plate 114. And the first air outlet 31 is not lower than the cover plate 114, and is lower than the second air outlet 32. The housing 3 also has a plurality of air inlet holes 37, the air inlet holes 37 are connected to the air outlet 115, and the air inlet holes 37 are not higher than the air outlet 115. In this way, when the first wind wheel 11 rotates, it drives the external air to spiral upward through the air inlet 37 and the air outlet 115 in sequence into the first wind wheel 11, and then flows out from the first air duct 112 toward the first air outlet 31 to form a purified airflow. During this flow process, the first fan blade 111 and the cover plate 114 cooperate to guide the purified airflow to spirally flow out of the first air duct 112 obliquely upward along the curved surface of the first fan blade 111 and the bottom surface of the cover plate 114, and flow to the first air outlet 31. After flowing out of the first air outlet 31 obliquely upward, it can also merge with the fan airflow located above, so that the fan airflow can bring the purified airflow to a farther place to improve the purification effect. Among them, the curved bottom surface of the cover plate 114 can also reduce the flow loss of air, which is conducive to increasing the air supply volume of the first wind wheel 11 and improving the energy efficiency of the purification module 1.

[0044] The above-mentioned air outlet 115 can be a gradually expanding opening, the diameter of the air outlet 115 gradually increases vertically upward, and the inner wall of the air outlet 115 bends and extends upward along the axis. In this way, it is beneficial for the purified airflow to flow along the inner wall of the air outlet 115 to the first air duct 112 and reduce the flow loss of air.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model also provides an air purifier, including the above-mentioned air outlet structure. The specific implementation process of the air outlet structure can refer to the above description, and this embodiment will not be repeated here. Since the air outlet structure has the above-mentioned technical effects, the air purifier having the air outlet structure also has the corresponding technical effects.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
