[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0045] Hereinafter, the air outlet component 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0046] like Figure 1-Figure 5 As shown, the air outlet component 100 includes a housing 1 and a fan 2. The housing 1 has a fan cavity 1a. Figure 5 A first air inlet 1b and an air outlet 1c which are respectively connected to the fan cavity 1a are formed on the shell 1; the fan 2 includes a wind wheel 21 arranged in the fan cavity 1a, so that when the fan 2 is working and the first air outlet 1c is opened, the wind wheel 21 rotates to allow the air flow to enter the fan cavity 1a from the first air inlet 1b and flow to the air outlet 1c.

[0047] The air outlet component 100 also includes an air outlet duct member 3, and there are multiple air outlet duct members 3, each of which has an air outlet cavity 3a, and each of which is formed with an outlet 3b connected to the air outlet cavity 3a. The multiple air outlet duct members 3 are replaceably connected to the air outlet 1c, and in at least two of the air outlet duct members 3, the number of outlets 3b and at least one of the air supply directions at the outlet 3b are different. In this way, when the air outlet duct member 3 is connected to the air outlet 1c, that is, the air outlet cavity 3a is connected to the air outlet 1c, the air flow of the fan cavity 1a flows from the air outlet 1c to the air outlet cavity 3a and is delivered from the outlet 3b; since the multiple air outlet duct members 3 are replaceably arranged, and in at least two of the multiple air outlet duct members 3, the number of outlets 3b and at least one of the air supply directions at the outlet 3b are different, the air outlet component 100 can have different air supply effects.

[0048] Therefore, the air outlet component 100 can replace different air outlet duct parts 3 so that the air outlet component 100 has different numbers of outlets 3b and / or different air supply directions at the outlets 3b, so as to meet the user's different needs for air volume and / or air supply direction. Therefore, through the overall structural layout design of the air outlet component 100, under the premise that the overall internal structure of the shell 1 and the fan 2 remains unchanged, the air outlet 1c can be coordinated with different air outlet duct parts 3 to achieve different air supply effects of the air outlet component 100, so that multiple air outlet duct parts 3 can be replaced on the same shell 1 structure, that is, by replacing the single component of the air outlet duct part 3 to achieve a variety of air supply effects of the air outlet component 100, the air outlet component 100 can be derived in multiple ways with the shell 1 as the main body, thereby avoiding the need to design multiple molds of the air outlet components 100 with different air supply effects separately. Only different air outlet duct parts 3 need to be replaced, which is beneficial to reducing the mold opening cost of the air outlet component 100, and can realize mass production of the air outlet component 100, effectively reducing production cost and production time.

[0049] Compared with some technologies, the air outlet components use a separate front air outlet or a separate rear air outlet. When different products are diffracted between different platforms, it is impossible to switch normally while ensuring that the indicators remain unchanged, and basically the module needs to be reopened; while in the embodiment of the present application, only different air outlet duct components 3 need to be replaced, and other components can remain unchanged. Seamless switching can be achieved on the same module (including the shell 1), which is suitable for the derivation of platform products.

[0050] The following takes two air outlet duct members 3 as an example. In the two air outlet duct members 3, the number of outlets 3b and one of the air supply directions at the outlets 3b are different.

[0051] For example, there are two air outlet duct members 3, namely, a first air outlet duct member 3 and a second air outlet duct member 3. Figure 1 and Figure 2The first air outlet duct piece 3 and the second air outlet duct piece 3 respectively have an outlet 3b, the outlet 3b of the first air outlet duct piece 3 faces the rear side of the air outlet component 100, and the outlet 3b of the second air outlet duct piece 3 faces the front side of the air outlet component 100. When the first air outlet duct piece 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the rear side; when the second air outlet duct piece 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the front side. Therefore, the air outlet component 100 can replace the first air outlet duct piece 3 and the second air outlet duct piece 3, so that the air outlet component 100 can realize rear side air delivery or front side air delivery. Of course, the air supply direction at the outlet 3b of the first air outlet duct piece 3 and the air supply direction at the outlet 3b of the second air outlet duct piece 3 are not limited to this, and it is only necessary to make the air supply directions at the outlets 3b of the two different; for example, the outlet 3b of the first air outlet duct piece 3 and the outlet 3b of the second air outlet duct piece 3 are both set forward, the airflow direction at the outlet 3b of the first air outlet duct piece 3 blows forward horizontally, and the airflow direction at the outlet 3b of the second air outlet duct piece 3 blows forward inclined (for example, inclined downward or inclined upward).

[0052] For example, combining Figure 2 and Figure 3 , the first air outlet duct member 3 has one outlet 3b, and the second air outlet duct member 3 has two outlets 3b. When the first air outlet duct member 3 or the second air outlet duct member 3 is connected to the air outlet 1c, the air outlet component 100 can supply air from the corresponding outlet 3b, and the air supply range of the second air outlet duct member 3 is greater than the air supply range of the first air outlet duct member 3. Therefore, the air outlet component 100 can replace the first air outlet duct member 3 and the second air outlet duct member 3 so that the air outlet component 100 has different air supply ranges. Of course, the number of outlets 3b of the first air outlet duct member 3 and the number of outlets 3b of the second air outlet duct member 3 are not limited to this, and the number of outlets 3b of the two only needs to be different; for example, the first air outlet duct member 3 has three outlets 3b, and the second air outlet duct member 3 has one or two outlets 3b, etc.

[0053] For example, combining Figure 2 and Figure 3The first air outlet duct piece 3 has an outlet 3b, which faces the front side of the air outlet component 100, and the second air outlet duct piece 3 has two outlets 3b, one of the two outlets 3b faces the rear side of the air outlet component 100, and the other outlet 3b faces the front side of the air outlet component 100. When the first air outlet duct piece 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the front side; when the second air outlet duct piece 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the front and rear sides. Therefore, the air outlet component 100 can replace the first air outlet duct piece 3 and the second air outlet duct piece 3, so that the air outlet component 100 has different air supply effects of delivering air to the rear side and delivering air to both the front and rear sides.

[0054] The following takes three air outlet duct members 3 as an example, in which two of the air outlet duct members 3 have different numbers of outlets 3b and at least one of the air supply directions at the outlets 3b, and the remaining one has the same structure as one of the two air outlet duct members 3 mentioned above.

[0055] For example, there are three air outlet duct members 3, which are respectively the first air outlet duct member 3, the second air outlet duct member 3 and the third air outlet duct member 3. Figure 1-Figure 3 , the first air outlet duct member 3 and the second air outlet duct member 3 each have an outlet 3b, the outlet 3b of the first air outlet duct member 3 faces the rear side of the air outlet component 100, and the outlet 3b of the second air outlet duct member 3 faces the front side of the air outlet component 100, and one of the first air outlet duct member 3 and the second air outlet duct member 3 has the same structure as the third air outlet duct member 3, that is, the number of outlets 3b and the air supply direction at the outlet 3b are the same; when the first air outlet duct member 3 is connected to the air outlet 1c, the air outlet component 100 can supply air toward the rear side, and when the second air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can supply air toward the front side; when the third air outlet duct component 3 is connected to the air outlet 1c, the third air outlet duct component 3 has the same structure as the first air outlet duct component 3, and the air outlet component 100 can supply air toward the rear side, or the third air outlet duct component 3 has the same structure as the second air outlet duct component 3, and the air outlet component 100 can supply air toward the front side.

[0056] For another example, the first air outlet duct piece 3 has one outlet 3b, the second air outlet duct piece 3 has two outlets 3b, and one of the first air outlet duct piece 3 and the second air outlet duct piece 3 has the same structure as the third air outlet duct piece 3; when the third air outlet duct piece 3 has the same structure as the first air outlet duct piece 3, the air supply ranges of the first air outlet duct piece 3 and the third air outlet duct piece 3 are the same, and the air supply range of the second air outlet duct piece 3 is larger than the air supply ranges of the first air outlet duct piece 3 and the third air outlet duct piece 3. Of course, the third air outlet duct piece 3 can also have the same structure as the second air outlet duct piece 3.

[0057] Similarly, in the first air outlet duct member 3 and the second air outlet duct member 3, the number of outlets 3b and the air supply direction at the outlets 3b are different. One of the first air outlet duct member 3 and the second air outlet duct member 3 has the same structure as the third air outlet duct member 3, which will not be repeated here.

[0058] It can be understood that one of the first air outlet duct component 3 and the second air outlet duct component 3 has the same structure as the third air outlet duct component 3, and a certain redundant design can be achieved, so that the third air outlet duct component 3 can be used as a redundant component to facilitate replacement of the damaged first air outlet duct component 3 or the second air outlet duct component 3, thereby improving the stability of the assembly production of the air outlet component 100.

[0059] The following takes three air outlet duct members 3 as an example. Among the three air outlet duct members 3, any two air outlet duct members 3 have different numbers of outlets 3b and different air supply directions at the outlets 3b.

[0060] For example, there are three air outlet duct pieces 3, namely the first air outlet duct piece 3, the second air outlet duct piece 3 and the third air outlet duct piece 3. For the first air outlet duct piece 3 and the second air outlet duct piece 3, the two have different numbers of outlets 3b, for the second air outlet duct piece 3 and the third air outlet duct piece 3, the two have different numbers of outlets 3b, and for the first air outlet duct piece 3 and the third air outlet duct piece 3, the two have different numbers of outlets 3b; or, for the first air outlet duct piece 3 and the second air outlet duct piece 3, the air supply directions at the outlets 3b of the two are different. Similarly, for the second air outlet duct piece 3 and the third air outlet duct piece 3, the air supply directions at the outlet 3b of the two are different, and for the first air outlet duct piece 3 and the third air outlet duct piece 3, the air supply directions at the outlet 3b of the two are different; or, for the first air outlet duct piece 3 and the second air outlet duct piece 3, the air supply directions at the outlet 3b of the two are different, and for the second air outlet duct piece 3 and the third air outlet duct piece 3, the two are different in the number of outlets 3b, and for the first air outlet duct piece 3 and the third air outlet duct piece 3, the two are different in the number of outlets 3b; and so on.

[0061] The following takes three air outlet duct members 3 as an example. Among the three air outlet duct members 3, any two air outlet duct members 3 have different numbers of outlets 3b and different air supply directions at the outlets 3b.

[0062] For example, there are three air outlet duct members 3, which are respectively the first air outlet duct member 3, the second air outlet duct member 3 and the third air outlet member 100. Figure 1-Figure 3The first air outlet duct member 3 has one outlet 3b, the second air outlet duct member 3 has two outlets 3b, and the third air outlet duct member 3 has three outlets 3b. The outlet 3b of the first air outlet duct member 3 faces the rear side of the air outlet component 100, and the two outlets 3b of the second air outlet duct member 3 face the front side of the air outlet component 100, and one of the two outlets 3b is located above the other. One of the three outlets 3b of the third air outlet duct member 3 faces the rear side of the air outlet component 100, and the other two outlets 3b face the front side of the air outlet component 100. b is toward the front side of the air outlet component 100, and one of the two outlets 3b is located above the other. When the first air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the rear side; when the second air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the front side, and the air delivery range toward the front side is larger; when the third air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can deliver air toward the front and rear sides, and the air delivery range of the air outlet component 100 is larger and the air delivery directions are more. Therefore, the air outlet component 100 can have different air delivery effects on the front side, the rear side, or both the front and rear sides, and different air delivery ranges by replacing the first air outlet duct component 3, the second air outlet duct component 3, and the third air outlet duct component 3.

[0063] Of course, when there are three air outlet duct members 3, two of the air outlet duct members 3 have different numbers of outlets 3b and air supply directions at the outlets 3b, and two of the air outlet duct members 3 have different numbers of outlets 3b and air supply directions at the outlets 3b.

[0064] For example, combined with Figure 1-Figure 3 , the first air outlet duct member 3 and the second air outlet duct member 3 respectively have an outlet 3b, the third air outlet duct member 3 has two outlets 3b, the outlet 3b of the first air outlet duct member 3 faces the rear side of the air outlet component 100, the outlet 3b of the second air outlet duct member 3 faces the front side of the air outlet component 100, one of the two outlets 3b of the third air outlet duct member 3 faces the rear side of the air outlet component 100, and the other outlet 3b faces the front side of the air outlet component 100; when the first air outlet duct member 3 is connected When the air outlet 1c is connected, the air outlet component 100 can supply air toward the rear side; when the second air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can supply air toward the front side; when the third air outlet duct component 3 is connected to the air outlet 1c, the air outlet component 100 can supply air toward the front and rear sides. Therefore, the air outlet component 100 can replace the first air outlet duct component 3, the second air outlet duct component 3, and the third air outlet duct component 3, so that the air outlet component 100 has different air supply effects on the front side, the rear side, or both the front and rear sides.

[0065] In addition, the number of the air outlet duct members 3 may be four or more.

[0066] It is worth noting that the air outlet component 100 can be applied to the air conditioner 200, for example, the air outlet component 100 is used for cooling or heating air supply of the air conditioner 200, or the air outlet component 100 is used for fresh air supply of the air conditioner 200. Of course, the application scenarios of the air outlet component 100 are not limited thereto, for example, it can be applied to other air outlet devices or equipment, such as an air purifier, etc.

[0067] According to the air outlet component 100 of the embodiment of the present invention, the air outlet component 100 can replace different air outlet duct parts 3 so that the air outlet component 100 has different numbers of outlets 3b and / or different air supply directions at the outlets 3b, so as to meet the user's different needs for air volume and / or air supply direction. Therefore, under the premise that the overall internal structure of the shell 1 and the fan 2 remains unchanged, the air outlet 1c can be coordinated with different air outlet duct parts 3 to achieve different air supply effects of the air outlet component 100, so that multiple air outlet duct parts 3 can be replaced on the same shell 1 structure, that is, the air outlet component 100 can have multiple air supply effects by replacing the single component of the air outlet duct part 3, so that the air outlet component 100 can be derived in various ways with the shell 1 as the main body, which is beneficial to reducing the mold opening cost of the air outlet component 100, and can realize mass production of the air outlet component 100, effectively reducing production cost and production time.

[0068] In some embodiments, Figure 1 and Figure 2 As shown, the multiple air outlet duct members 3 include a first air outlet duct member 31 and a second air outlet duct member 32. The air supply direction at one of the outlets 3b of the first air outlet duct member 31 is opposite to the air supply direction at one of the outlets 3b of the second air outlet duct member 32. Therefore, the air outlet component 100 can have a different air supply direction by replacing the first air outlet duct member 31 and the second air outlet duct member 32, so that the air conditioner 200 has different air supply areas.

[0069] In the above technical solution, the first air outlet duct member 31 has one or more outlets 3b, and the second air outlet duct member 32 has one or more outlets 3b. The number of outlets 3b of the first air outlet duct member 31 and the number of outlets 3b of the second air outlet duct member 32 can be equal or different.

[0070] For example, in Figure 1 and Figure 2In the example, the first air outlet duct member 31 or the second air outlet duct member 32 is connected to the air outlet 1c of the housing 1, and the first air outlet duct member 31 and the second air outlet duct member 32 both have an outlet 3b, the outlet 3b of the first air outlet duct member 31 supplies air toward the rear side, and the outlet 3b of the second air outlet duct member 32 supplies air toward the front side. Alternatively, the first air outlet duct member 31 and the second air outlet duct member 32 both have two outlets 3b, one of the two outlets 3b of the first air outlet duct member 31 supplies air toward the front side, and the other outlet 3b supplies air toward the rear side, and the two outlets 3b of the second air outlet duct member 32 both supply air toward the front side, and one of the outlets 3b is located above the other outlet 3b.

[0071] In some embodiments, Figure 1-Figure 3 As shown, the plurality of air outlet duct members 3 include a first air outlet duct member 31, a second air outlet duct member 32 and a third air outlet duct member 33. The outlet 3b of the first air outlet duct member 31 is configured to be arranged along a first direction (eg Figure 1 The outlet 3b of the second air outlet duct member 32 is configured to supply air in the forward direction (in the front-to-back direction), the outlet 3b of the second air outlet duct member 32 is configured to supply air in the reverse direction along the first direction, the outlet 3b of the third air outlet duct member 33 is multiple, and one of the outlets 3b of the third air outlet duct member 33 is configured to supply air in the forward direction along the first direction, and the other outlet 3b is configured to supply air in the reverse direction along the first direction. Thus, by replacing the first air outlet duct member 31, the second air outlet duct member 32, and the third air outlet duct member 33 at the air outlet 1c of the air outlet component 100, the air outlet component 100 can have different air supply effects of supplying air in the forward direction, supplying air in the reverse direction along the first direction, and supplying air in both the forward direction and the reverse direction along the first direction.

[0072] Among them, "forward" and "reverse" do not refer to a specific direction, but are relative concepts; taking the first direction as the front-to-back direction as an example, the forward air supply along the first direction is the forward air supply, and the reverse air supply along the first direction is the backward air supply, or the forward air supply along the first direction is the backward air supply, and the reverse air supply along the first direction is the forward air supply. Of course, the first direction is not limited to the front-to-back direction, for example, the first direction can also be the left-right direction, or the up-down direction.

[0073] In addition, in the above technical solution, the number of outlets 3b of the first air outlet duct member 31 is one, two or more, the number of outlets 3b of the second air outlet duct member 32 is one, two or more, and the number of outlets 3b of the third air outlet duct member 33 can be two, three or more.

[0074] Among them, Figure 4 and Figure 5As shown, the air outlet cavity 3a of the third air outlet duct member 33 has an air outlet main path 33a, a first air outlet branch 33b and a second air outlet branch 33c. The first air outlet branch 33b is connected to the air outlet main path 33a and one of the outlets 3b, and the second air outlet branch 33c is connected to the air outlet main path 33a and the other outlet 3b. Thus, the airflow in the duct cavity flows from the air outlet 1c to the air outlet main path 33a, and the airflow in the air outlet main path 33a is divided into the first air outlet branch 33b and the second air outlet branch 33c and is sent out from the corresponding outlet 3b.

[0075] For example, in Figure 4 and Figure 5 In the example, the third air outlet duct member 33 has two outlets 3b, one of which faces the front and the other faces the rear. The air outlet 1c of the shell 1 is connected to the main air outlet path 33a, and the air flow can flow from the air outlet 1c to the main air outlet path 33a. The main air outlet path 33a is connected to the first air outlet branch 33b and the second air outlet branch 33c. The first air outlet branch 33b is connected to the outlet 3b facing the front, and the second air outlet branch 33c is connected to the outlet 3b facing the rear. In this way, the air outlet component 100 can achieve the air supply effect of supplying air to the front and rear sides; at this time, one of the first air outlet duct member 31 and the second air outlet duct member 32 is configured to supply air forward, and the other is configured to supply air backward.

[0076] In some embodiments, Figure 3 and Figure 5 As shown, the third air outlet duct member 33 has two outlets 3b. At the intersection of the first air outlet branch 33b and the second air outlet branch 33c, the cross-sectional area of ​​the first air outlet branch 33b is smaller than the cross-sectional area of ​​the second air outlet branch 33c. Therefore, at the intersection, the cross-sectional area of ​​the air flow of the first air outlet branch 33b is smaller than the cross-sectional area of ​​the air flow of the second air outlet branch 33c. Then, the air supply volume of the corresponding outlet 3b of the first air outlet branch 33b is smaller than that of the corresponding outlet 3b of the second air outlet branch 33c. The air supply volume can reduce the noise generated by the first air outlet branch 33b, which is beneficial to improving the user experience and comfort. At the same time, compared with some technologies that reduce noise by sacrificing the air supply volume of the air duct, in the embodiment of the present application, although the air supply volume of the first air outlet branch 33b is relatively small, the second air outlet branch 33c can also supply air, so as to take into account the sound quality and air supply volume of the air outlet component 100 at the same time, so as to make the air outlet component 100 achieve large air volume and low noise air supply, so as to effectively solve the user pain point problem.

[0077] When the air outlet component 100 is used in the air conditioner 200, the outlet 3b corresponding to the first air outlet branch 33b can face the user, and the outlet 3b corresponding to the second air outlet branch 33c can face away from the user. The cross-sectional area of ​​the first air outlet branch 33b is smaller than the cross-sectional area of ​​the second air outlet branch 33c, so that the noise transmitted from the outlet 3b of the first air outlet branch 33b to the user is less. In addition, the noise transmitted from the outlet 3b of the second air outlet branch 33c is away from the user, which can reduce the noise transmitted from the second air outlet branch 33c to the user.

[0078] For example, combined with Figure 3 and Figure 5 The third air outlet duct member 33 is connected to the air outlet 1c of the shell 1, and the third air outlet duct member 33 includes two outlets 3b, one of which can supply air toward the front side (supply air toward the user), and the other outlet 3b can supply air toward the rear side. The first air outlet branch 33b is connected to the front outlet 3b, and the second air outlet branch 33c is connected to the rear outlet 3b. At the intersection of the first air outlet branch 33b and the second air outlet branch 33c, the cross-sectional area of ​​the first air outlet branch 33b is smaller than the cross-sectional area of ​​the second air outlet branch 33c. Then, the air flow rate of the main air outlet path 33a flowing to the first air outlet branch 33b is smaller than the air flow rate of the main air outlet path 33a flowing to the second air outlet branch 33c. Therefore, the noise of the first air outlet branch 33b is smaller than the noise of the second air outlet branch 33c, thereby reducing the noise transmitted to the side where the user is located, thereby improving the user's comfort and experience.

[0079] Optionally, the cross-sectional area of ​​the first air outlet branch 33b gradually increases along the air flow direction in the first air outlet branch 33b, so as to further reduce the noise of the first air outlet branch 33b to a certain extent.

[0080] Of course, in a usage scenario where the noise requirement is not high, at the intersection of the first air outlet branch 33b and the second air outlet branch 33c, the cross-sectional area of ​​the first air outlet branch 33b can also be equal to the cross-sectional area of ​​the second air outlet branch 33c.

[0081] In some embodiments, Figure 5 As shown, the air outlet 1c is formed on the housing 1 in the second direction (eg Figure 1 On one side of the vertical direction in the middle, at the intersection of the first air outlet branch 33b and the second air outlet branch 33c, the first air outlet branch 33b is in the third direction (for example Figure 1The width in the left and right directions in the middle is A1, the width in the second direction of the first air outlet branch 33b is H1, the width in the third direction of the second air outlet branch 33c is A2, the distance between the intersection and the air outlet 1c in the second direction is H2, 0.15≤A1 / A2≤0.5, 0.2≤H1 / H2≤0.45, so that the ratio of the cross-sectional area of ​​the first air outlet branch 33b to the cross-sectional area of ​​the second air outlet branch 33c is within a reasonable range, so that the air flow diverted from the main air outlet path 33a to the first air outlet branch 33b is smaller than the air flow of the second air outlet branch 33c, thereby ensuring that the airflow in the second air outlet branch 33c is the main supply airflow, and the airflow in the first air outlet branch 33b is the auxiliary supply airflow, thereby improving the air supply efficiency of the air outlet component 100 and at the same time, helping to reduce the noise of the first air outlet branch 33b and improve the comfort of the user.

[0082] Optionally, the ratio A1 / A2 of the width of the first air outlet branch 33b in the third direction to the width of the second air outlet branch 33c in the third direction can be 0.15, 0.2, 0.3, 0.35, 0.4, or 0.5, etc.; the ratio H1 / H2 of the width of the first air outlet branch 33b in the second direction to the distance between the intersection position and the air outlet 1c in the second direction can be 0.2, 0.25, 0.3, 0.4, or 0.45, etc.

[0083] In some embodiments, Figure 5 As shown, the housing 1 includes a volute tongue 1g, which defines a side edge of the air outlet 1c in the third direction, and a diffusion angle α is formed between the two opposite side walls of the air outlet main path 33a in the third direction, 12°≤α≤30°. As a result, along the flow direction of the airflow, the cross-sectional area of ​​the air outlet main path 33a (the cross-sectional area of ​​the airflow flow) gradually increases, so that the airflow flowing from the air outlet 1c into the air outlet main path 33a can be smoothly decelerated, so as to effectively form a static pressure zone in the air outlet main path 33a, so that the airflow is more smoothly diverted from the outlet mainstream to the first air outlet main path 33a and the second air outlet main path 33a, which is conducive to reducing the noise of the first air outlet branch 33b and the second air outlet branch 33c and improving the comfort of the user.

[0084] It can be understood that the main air outlet path 33a is located between the air outlet 1c and the intersection position, and in the air flow direction of the air outlet cavity 3a, the cross-sectional area of ​​the main air outlet path 33a gradually increases, so that the distance between the two opposite side walls of the main air outlet path 33a in the third direction gradually increases, so that a diffusion angle α is formed between the two opposite side walls of the main air outlet path 33a in the third direction, which can slow down the air flow speed of the main air outlet path 33a, so that the air flow flows smoothly along the wall surface of the main air outlet path 33a to the first air outlet branch 33b and the second air outlet branch 33c.

[0085] It can be understood that the volute tongue 1g defines the air outlet 1c, and the volute tongue 1g is located on the airflow path of the airflow in the fan chamber 1a to the air outlet 1c. The volute tongue 1g can guide part of the airflow into the working cycle of the fan 2. Therefore, the volute tongue 1g can reduce part of the wind resistance of the airflow, which is beneficial to reduce noise.

[0086] In the embodiment of the present application, the connection method between the housing 1 and the air outlet duct member 3 is not specifically limited. Figure 1-Figure 3 As shown, a sliding structure is formed on one side edge of the air outlet 1c in the third direction, and the sliding structure and the air outlet duct member 3 are slidably cooperated to disassemble and assemble the air outlet duct member 3, which facilitates the assembly of the shell 1 and the air outlet duct member 3 and ensures that the connection between the air outlet duct member 3 and the shell 1 is reliable.

[0087] For example, the sliding structure is located at the air outlet 1c, a sliding groove is formed in the sliding structure, and a sliding rail is formed on one side of the air outlet duct member 3 that cooperates with the transfer structure. The sliding rail and the sliding groove cooperate to facilitate the installation of the air outlet duct member 3 and realize the connection and cooperation between the air outlet duct member 3 and the shell 1.

[0088] In some embodiments, Figure 5 and Figure 6 As shown, at least a portion of the circumferential cavity wall of at least one air outlet duct member 3 has a noise reduction structure 4. The noise reduction structure 4 can effectively absorb the noise in the air outlet duct member 3 to reduce the air supply noise of the air outlet duct member 3, improve the sound quality of the air outlet component 100, reduce the impact of noise on the user, and help improve the user's comfort.

[0089] Optionally, at least a portion of the circumferential cavity wall of at least one of the first air outlet duct member 31, the second air outlet duct member 32, and the third air outlet duct member 3 has a noise reduction structure 4. Of course, in other examples, if there are four or more air outlet duct members 3, at least a portion of the circumferential cavity wall of at least one of the remaining air outlet duct members 3 except the first air outlet duct member 31, the second air outlet duct member 32, and the third air outlet duct member 3 has a noise reduction structure 4.

[0090] For example, in Fig.14 In the example, the air outlet duct member 3 with the noise reduction structure 4 has significantly reduced noise in the air outlet component 100 compared to the air outlet duct member 3 without the noise reduction structure 4.

[0091] In some embodiments, Figure 5 and Figure 6 As shown, when at least a portion of the circumferential side cavity wall of the third air outlet duct member 3 has a noise reduction structure 4, at least a portion of the circumferential side cavity wall of the first air outlet branch 33b has a noise reduction structure 4, and / or at least a portion of the circumferential side cavity wall of the second air outlet branch 33c has a noise reduction structure 4.

[0092] Among them, at least a portion of the surrounding side cavity wall of the first air outlet branch 33b has a noise reduction structure 4, and the noise reduction structure 4 can effectively absorb the noise in the first air outlet branch 33b to reduce the air supply noise of the first air outlet branch 33b, improve the sound quality of the air outlet component 100, reduce the impact of noise on the user, and help improve the comfort of the user; at least a portion of the surrounding side cavity wall of the second air outlet branch 33c has a noise reduction structure 4, and the noise reduction structure 4 can effectively absorb the noise in the second air outlet branch 33c to reduce the air supply noise of the second air outlet branch 33c, and can also improve the sound quality of the air outlet component 100, reduce the impact of noise on the user, and help improve the comfort of the user.

[0093] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0094] For example, combined with Figure 1 and Figure 4 The cross section of the first air outlet branch 33b and the second air outlet branch 33c is a quadrilateral structure, the peripheral side cavity wall of the first air outlet branch 33b and the peripheral side cavity wall of the second air outlet branch 33c respectively include four side cavity walls, each of the four side cavity walls of the first air outlet branch 33b has a noise reduction structure 4, and three of the four side cavity walls of the second air outlet branch 33c respectively have a noise reduction structure 4. Among them, the multiple noise reduction structures 4 of the first air outlet branch 33b are arranged at intervals, and the multiple noise reduction structures 4 of the second air outlet branch 33c are arranged at intervals.

[0095] In some embodiments, Figure 5-Figure 6 and Fig.10 As shown, the noise reduction structure 4 includes an inner plate 41 and an outer plate 42. The inner plate 41 is used to define the wall surface of the air outlet cavity 3a, and a plurality of noise reduction holes 41a are formed on the inner plate 41. The outer plate 42 is arranged on the outer side of the inner plate 41, and the outer plate 42 and the inner plate 41 define a noise reduction cavity 4a. The noise reduction holes 41a are connected to the noise reduction cavity 4a, and the noise reduction holes 41a and the noise reduction cavity 4a that are connected to each other can form a Helmholtz silencer, so that part of the air in the noise reduction cavity 4a is rubbed back and forth in the noise reduction holes 41a to consume sound energy when the noise propagates. As a result, the noise reduction structure 4 can effectively reduce noise. At the same time, the double-layer partition design of the inner plate 41 and the outer plate 42 can play a role in sound insulation to isolate the noise in the air outlet cavity 3a to a certain extent, thereby effectively achieving the noise reduction effect and further reducing the noise. In some embodiments, as Figure 6 and Fig.10As shown, the equivalent diameter of the noise reduction hole 41a is d, 3mm≤d≤15mm, so that the equivalent diameter of the noise reduction hole 41a is within a suitable range to ensure that the noise is reflected multiple times in the noise reduction hole 41a, so that the noise reduction hole 41a can effectively absorb the noise. Optionally, the equivalent diameter d of the noise reduction hole 41a can be 3mm, 4mm, 5mm, 8mm, 12mm, or 15mm, etc.

[0096] It is understandable that the shape of the noise reduction hole 41a is not limited, for example, it can be circular, elliptical, or quasi-circular or polygonal (such as a pentagon, etc.), etc. When the noise reduction hole 41a is a circular hole, the equivalent diameter of the noise reduction hole 41a is the diameter of the noise reduction hole 41a.

[0097] In some embodiments, Fig.10 As shown, a plurality of noise reduction holes 41a are formed on the inner plate 41, and the opening rate of the inner plate 41 is s, 0.24≤s≤0.8, so that the noise reduction structure 4 has a good noise reduction effect, while taking into account the weakening effect of the noise reduction holes 41a on the inner plate 41, thereby taking into account the structural strength and reliability of the inner plate 41. Optionally, the opening rate s of the inner plate 41 can be 0.24, 0.3, 0.35, 0.4, 0.6, or 0.8, etc.

[0098] It should be noted that the porosity is the ratio of the total area of ​​the sieve holes on the sieve plate to the area of ​​the open area (also called the effective mass transfer area). The porosity of the inner plate 41 can be understood as the ratio of the area occupied by the noise reduction holes 41a on the inner plate 41 to the surface area of ​​the thickness side of the inner plate 41.

[0099] In some embodiments, Figure 6 As shown, the thickness of the outer plate 42 is t1, 2mm≤t1≤4mm, so as to ensure that the outer plate 42 has sufficient thickness, which can improve the strength of the air outlet duct member 3, and is conducive to protecting the safety of the air outlet duct member 3. At the same time, the sound insulation ability of the outer plate 42 can be improved to a certain extent. Optionally, the thickness t1 of the outer plate 42 can be 2mm, 2.5mm, 3mm, or 4mm, etc.

[0100] Optionally, the outer plate may be a plastic member or the like.

[0101] In some embodiments, Figure 6 and Fig.10 As shown, the noise reduction structure 4 also includes a sound absorbing member 5 (such as sound absorbing cotton, which can be optionally a sound absorbing sponge or a sound absorbing glass fiber sponge, etc.). The sound absorbing member 5 is arranged in the noise reduction cavity 4a and the sound absorbing member 5 covers a plurality of noise reduction holes 41a, so that the sound absorbing member 5 can further absorb noise to reduce the noise in the air outlet cavity 3a and improve the user's comfort.

[0102] It should be noted that the sound absorbing member 5 has countless interconnected pores. When the sound waves are incident on the surface of the sound absorbing member 5, they will enter the interior of the material along the pores, stimulate the air in the pores to vibrate, and produce relative movement between the vibrating air and the fixed ribs of the sound absorbing member 5. Due to the viscosity of the air, corresponding viscous resistance is generated in the pores, forcing this relative movement to produce friction loss and convert into heat energy, thereby achieving the sound absorption effect.

[0103] It is worth noting that the operation of the fan 2 (such as the rotation of the wind wheel 21, etc.) and the flow of air in the housing 1 are noise sources. The noise is transmitted from the air outlet 1c in the fan chamber 1a to the air outlet chamber 3a, and then radiated from the outlet 3b to the room. In this application, a noise reduction structure 4 is arranged on the propagation path of the noise, and the noise reduction effect is achieved through the sound-absorbing effect of the multiple noise reduction holes 41a formed by the inner plate 41, the sound-absorbing effect of the sound-absorbing member 5, and the sound insulation effect of the double-layer partition structure of the inner plate 41 and the outer plate 42, so that the air supply at the outlet 3b has a significant noise reduction effect.

[0104] In some embodiments, Figure 6 As shown, the thickness of the sound absorbing member 5 is t2, 3mm≤t2≤30mm, to ensure that the sound absorbing member 5 has a suitable thickness and can absorb noise well. Optionally, the thickness t2 of the sound absorbing member 5 can be 3mm, 5mm, 10mm, 20mm, or 30mm.

[0105] In some embodiments, Figure 4 As shown, the first air inlet 1b is suitable for being connected to the outdoors, so that the first air inlet 1b is constructed as a fresh air inlet, so that fresh air from the outdoors can flow from the first air inlet 1b to the fan chamber 1a and be sent out from the corresponding outlet 3b, so that the air outlet component 100 can introduce fresh air from the outdoors into the indoors, reduce the turbidity of the indoor air, and realize the circulation of indoor and outdoor air, which is beneficial to improving the comfort of the users.

[0106] The shell 1 is also formed with a second air inlet 1d connected to the fan chamber 1a, and the second air inlet 1d is suitable for being connected to the room so that the second air inlet 1d is constructed as an indoor air inlet. In this way, the indoor air can flow from the second air inlet 1d to the fan chamber 1a and be sent out from the corresponding outlet 3b to realize the circulation of indoor air.

[0107] For example, in Figure 4In the example, the shell 1 is formed with a first air inlet 1b and a second air inlet 1d, the first air inlet 1b and the second air inlet 1d are respectively connected to the fan chamber 1a, the first air inlet 1b is located on the upper side of the second air inlet 1d, the first air inlet 1b is connected to the outdoors through the fresh air duct 6, and the second air inlet 1d is connected to the indoors, thereby, the air outlet component 100 can introduce outdoor fresh air into the indoors through the first air inlet 1b to realize indoor and outdoor air circulation and improve the freshness and comfort of the indoor air; the air outlet component 100 can send the indoor air out from the corresponding outlet 3b through the second air inlet 1d to realize indoor air circulation.

[0108] In other embodiments of the present application, the first air inlet 1b may also be adapted to be connected to the indoor air, so that the first air inlet 1b is configured as an indoor air inlet.

[0109] In some embodiments, Figure 12-13 As shown, an air inlet cavity 1e is also formed in the shell 1. The air inlet cavity 1e is connected to the upstream of the fan cavity 1a in the direction of air flow. The first air inlet 1b is connected to the fan cavity 1a through the air inlet cavity 1e. The air first flows to the air inlet cavity 1e and then to the fan cavity 1a through the first air inlet 1b, and then flows to the air outlet cavity 3a and is delivered from the corresponding outlet 3b.

[0110] The air outlet component 100 also includes a purification component 5, which includes a purification core 51 (such as a HEPA net) arranged in the air inlet chamber 1e, and the windward surface of the purification core 51 is a curved surface structure. In other words, the side surface (i.e., the windward surface) of the airflow entering the purification core 51 is a curved surface structure. It should be noted here that the windward surface of the purification core 51 can be a continuous surface, for example, it can be a fitting surface composed of multiple points. Of course, the windward surface of the purification core 51 is a curved surface structure, which can be determined according to the specific material selection of the purification core 51. For example, the purification core 51 can include an ordinary filter screen, a high-efficiency air filter core (i.e., HEPA), an IPD, etc. As a result, the effective purification area of ​​the purification core 51 can be increased, thereby improving the purification efficiency of the purification core 51.

[0111] Thus, the air flows from the first air inlet 1b to the air inlet chamber 1e and passes through the purification component 5 (for example, the purification core 51), so that the purification component 5 can purify the air (the purification may include at least one of filtering, disinfecting and sterilizing the air), thereby improving the indoor air quality and helping to improve the user's comfort.

[0112] For example, combined with Fig.12 and Fig.13, the windward side of the purification core 51 (i.e., the side surface where the airflow enters the purification core 51) is arranged toward the first air inlet 1b, and the leeward side of the purification core 51 (i.e., the side surface where the airflow flows out of the purification core 51) is arranged toward the inlet of the fan chamber 1a. Thus, the airflow flows from the first air inlet 1b to the purification core 51, then from the purification core 51 to the fan chamber 1a, and then from the fan chamber 1a to the air outlet chamber 3a and flows from the corresponding outlet 3b to the room. The overall flow path is short, with few turns, small flow wind resistance, large air volume, low noise, and smoother airflow.

[0113] Optionally, the purification component 5 is configured to be suitable for entering and exiting the air inlet chamber 1e through the drawer opening 1f on the housing 1. Therefore, when installing the purification component 5, the purification component 5 can be pushed into the housing 1 through the drawer opening 1f and adapted to the air inlet chamber 1e. When disassembling the purification component 5, the purification component 5 can be pulled out from the drawer opening 1f, so that the purification component 5 can be cleaned or the purification core 51 can be replaced. Therefore, the purification component 5 can be disassembled and assembled without disassembling the housing 1, which is convenient for users to disassemble and assemble the purification component 5.

[0114] In some embodiments, Fig.12 As shown, the windward surface and the leeward surface of the purification core 51 are curved surface structures with the same bending direction, that is, the center of the windward surface and the center of the leeward surface are located on the same side of the thickness of the purification core 51. For example, the thickness direction of the purification core 51 is the front-to-back direction, and the center of the windward surface and the center of the leeward surface are both located on the same side of the thickness of the purification core 51 and both are located on the same straight line parallel to the front-to-back direction, so that the purification core 51 is an arc-shaped plate with a length centerline extending along the curve. In other words, the side surface of the purification core 51 where the airflow flows into the purification core 51, that is, the windward surface, is a curved surface structure, and the side surface of the purification core 5131 where the airflow flows out of the purification core 5131, that is, the leeward surface, is also a curved surface structure, and the purification core 51 is an arc-shaped plate with a length centerline extending along the curve. As a result, the structure of the purification core 51 is simple and easy to process.

[0115] Optionally, the curved surface is understood in a broad sense, and a non-plane is a curved surface, for example, it may be a spherical surface, a cylindrical surface, or a surface formed by a plurality of planes being bent and connected.

[0116] In some embodiments, in combination Fig.12 and Fig.13 As shown, the shell 1 may have an arc track, and the purification component 5 cooperates with the arc track to slide smoothly along the arc track and enter and exit the air inlet cavity 1e through the drawer opening 1f on the shell 1. That is, when installing the purification component 5, the purification component 5 can be pushed into the shell 1 through the drawer opening 1f and slid to the working position along the arc track. When removing the purification component 5, the purification component 5 can be pulled along the arc track and pulled out from the drawer opening 1f, so that the purification device can be cleaned, replaced, etc.

[0117] As a result, the purification component 5 is convenient for disassembly and assembly, which is conducive to the cleaning and replacement of the purification component 5, and ensures that the purification component 5 can slide along the set arc track during the disassembly and assembly process, ensuring the smoothness and stability of the pull-out, avoiding the occurrence of sliding jams, jams and other problems. In addition, through the design of the arc track, the external space occupied by the purification component 5 after being pulled out of the shell 1 can be further saved. In other words, only a smaller operating space is required to smoothly pull out the purification component 5.
