Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purifier with dual fans and dual air ducts. Background Technology

[0002] With societal development, people have increasingly higher demands for air quality. Currently, air purifiers are devices used to remove pollutants (such as particulate matter, formaldehyde, odors, bacteria, etc.) from indoor air, improving air quality. Air purifiers are widely used in homes, offices, shopping malls, factories, and other places. As living standards improve, people also have higher requirements for the aesthetics, purification capabilities, and noise levels of air purifiers.

[0003] Air purifiers typically consist of a housing and components such as a fan and filter located within it. The housing has an air inlet and an air outlet. An air inlet grille is usually installed at the air inlet of the housing; the grille serves a protective function, such as preventing debris from entering the air purifier and preventing users from accidentally touching the internal structure.

[0004] However, because air purifiers generate fan noise and internal turbulence noise during operation, the hollow structure in the grille at the air inlet directly exposes the sound source, thus directly transmitting the noise to the external environment. This results in the air purifier being quite noisy during operation, affecting the user experience. Utility Model Content

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

These descriptions are appropriate when these elements are in the positions shown in the drawings.

[0050] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a structural schematic diagram of an air purifier (hereinafter referred to as "air purifier") with dual fans and dual air ducts provided in this embodiment of the utility model. Figure 2 yes Figure 1 The diagram shown is an exploded structural diagram of an air purifier. Figure 3 yes Figure 1 The diagram shown is a structural schematic of an air purifier from another perspective. Figure 4 yes Figure 3 The diagram shown is a cross-sectional view of an air purifier along the A1-A2 position. Figure 5 yes Figure 1 The diagram shown is a structural schematic of an air purifier from another perspective. Figure 6 yes Figure 5 The diagram shown is a cross-sectional view of an air purifier along the B1-B2 section. It can be understood that... Figure 6 The black arrows in the diagram indicate the direction of gas flow. The air purifier may include: a housing 10 and two fan assemblies 20.

[0051] The equipment housing 10 may include a mounting housing 11 and a guide cover 12. The mounting housing 11 has a front air inlet k1 and two opposite side air outlets k2. The guide cover 12 is installed outside the front air inlet k1 of the mounting housing 11 and can block the front air inlet k1. An annular air inlet channel x1 is formed between the guide cover 12 and the mounting housing 11, and the annular air inlet channel x1 communicates with the front air inlet k1. The annular air inlet channel x1 and the front air inlet k1 form a continuous airflow channel, so that outside air can enter the gap between the guide cover 12 and the mounting housing 11 from the annular air inlet channel x1, and then enter the interior of the mounting housing 11 from the front air inlet k1.

[0052] Both fan assemblies 20 are installed within the device housing 10. The air inlets of both fan assemblies 20 are connected to the front air inlet k1 of the housing 11, and the air outlets of both fan assemblies 20 are connected to two side air outlets k2, respectively. The axes of the two fan assemblies 20 can be parallel, and their arrangement direction can be perpendicular to the axis of either fan assembly 20. Thus, by having the two fan assemblies 20 discharge air from the two side air outlets k2, the air purifier achieves bidirectional airflow, improving both the air purifier's and the overall performance. Furthermore, the parallel arrangement of the two fan assemblies 20 reduces the overall thickness of the air purifier. For wall-mounted air purifiers, this further reduces the space occupied and enhances the user experience.

[0053] In one exemplary embodiment, the air intake path of the air purifier can be as follows: external airflow enters the front air intake k1 of the mounting housing 11 through the annular air intake channel x1 between the guide cover 12 and the mounting housing 11, and after passing through the front air intake k1 of the mounting housing 11, it enters the two fan assemblies 20 located inside the mounting housing 11, and flows out from the two side air outlets k2 of the mounting housing 11 under the drive of the two fan assemblies 20.

[0054] In this embodiment of the invention, by fitting the mounting housing 11 and the air guide cover 12 with a gap, the air purifier's air intake function is achieved while simultaneously shielding the fan assembly 20 inside the mounting housing 11, thereby improving the air purifier's aesthetics. Furthermore, the relatively uniform air intake distribution within the annular air intake space avoids turbulent noise caused by localized high-speed airflow. In addition, the air guide cover 12 physically shields the air purifier's internal noise (such as fan noise and duct turbulence noise). For example, the sound waves of internal noise cannot directly escape from the front air outlet. Blocked by the air guide cover 12, some sound waves need to detour through the annular air intake channel x1 before escaping, while others are reflected by the air guide cover, increasing the length and complexity of the internal noise propagation path. This causes the noise to gradually attenuate during transmission, achieving a noise shielding effect.

[0055] In summary, this utility model embodiment provides an air purifier including a housing 10 and two fan assemblies 20. The housing 10 includes a mounting housing 11 and a guide cover 12. The mounting housing 11 has a front air inlet k1 and two opposite side air outlets k2. The guide cover 12 can block the front air inlet k1, and there is an annular air intake channel x1 between the guide cover 12 and the mounting housing 11, communicating with the front air inlet k1. Thus, through the clearance fit between the mounting housing 11 and the guide cover 12, the air intake function of the air purifier is realized while improving the aesthetics of the air purifier. Furthermore, the uniform distribution of air intake through the annular air intake channel can optimize the airflow distribution and avoid turbulent noise caused by local high-speed airflow. The guide cover 12 can also physically block the internal noise of the air purifier (such as fan noise and duct turbulence noise), achieving a noise shielding effect. This can solve the problem of high noise during operation of air purifiers in related technologies, thereby improving the user experience.

[0056] In addition, by using two fan assemblies 20 to discharge air from two side air outlets k2 respectively, the air purifier can achieve bidirectional air discharge function, improve the performance of the air purifier and the whole machine, and the two fan assemblies 20 arranged side by side can reduce the overall thickness of the air purifier.

[0057] Please refer to Figure 2 and Figure 4In one optional embodiment, the mounting housing 11 may have a front end face d1, with a front air inlet k1 formed in the middle region of the front end face d1, and a guide cover 12 connected to the front end face d1. The front end face d1 gradually slopes towards the fan assembly 20 from the outside in. The front end face d1 may be annular; for example, the front end face d1 may have an outer ring edge and an inner ring edge. The inner ring edge may be the edge of the front air inlet k1, and in a direction parallel to the axial direction of the fan assembly 20, the inner ring edge is located on the side of the outer ring edge closer to the fan assembly 20.

[0058] Thus, by tilting the front end face d1 of the mounting housing 11, the gas flow channel at the annular air inlet channel x1 gradually increases along the gas flow direction, forming a gradually expanding flow channel structure, which can reduce the airflow resistance at the annular air inlet channel x1, optimize the gas flow characteristics, and thereby improve the air volume performance of the air purifier.

[0059] For example, the included angle α between the front end face d1 and the first plane s1 can be in the range of 10° to 60°. For example, the included angle α between the front end face d1 and the first plane s1 can be 10°, 15°, 20°, 45° or 60°. The first plane s1 can be a virtual plane perpendicular to the axis of the fan assembly 20.

[0060] Please refer to Figure 4 In an optional embodiment, the device housing 10 may further include a plurality of connectors 13 located between the flow guide cover 12 and the mounting housing 11, and arranged around the front air inlet k1 of the mounting housing 11. The two ends of each connector 13 are fixedly connected to the flow guide cover 12 and the mounting housing 11, respectively. For example, the connector 13 may be a connecting rod, and the two ends of the connecting rod may be welded to the flow guide cover 12 and the mounting housing 11, respectively. Alternatively, the flow guide cover 12, the plurality of connectors 13, and the mounting housing 11 may be an integrally formed structure.

[0061] In one optional embodiment, the two ends of the connector 13 are respectively connected to the air guide cover 12 and the mounting housing 11, and the connector 13 is detachably connected to at least one of the air guide cover 12 and the mounting housing 11. For example, the connector 13 can be a connecting bolt, with both ends threadedly connected to the air guide cover 12 and the mounting housing 11. Alternatively, the air guide cover 12 and the mounting housing 11 can be connected by a snap-fit ​​or magnetic connection via the connector 13. Thus, since the air guide cover 12 is a detachable structure, it facilitates cleaning the internal space of the air purifier, thereby improving the user experience.

[0062] Please refer to Figure 2 and Figure 7 , Figure 7 yes Figure 3The diagram shows a cross-sectional structure of an air purifier along the C1-C2 position. In an optional embodiment, the mounting housing 11 may include an outer shell 111 and an inner shell 112 installed in the outer shell 111. The air purifier also includes a filter assembly 30. The inner shell 112 has a receiving groove c1 on the side facing the air guide cover 12. The opening of the receiving groove c1 is a front air inlet k1. The bottom of the receiving groove c1 has two vents k3, which are respectively connected to the air inlets of two fan assemblies 20. The filter assembly 30 is located in the receiving groove c1.

[0063] Installing the filter assembly 30 in the receiving groove c1 can improve the stability of the filter assembly 30 and increase the distance between the filter assembly 30 and the guide cover 12, thereby making the airflow entering the filter assembly 30 more uniform. For example, the filter assembly 30 may include a high efficiency particulate air filter (HEPA) filter, a HEPA filter with activated carbon composite filter, a formaldehyde removal filter, or an electrostatic dust removal filter, etc.

[0064] Please refer to Figure 2 , Figure 4 and Figure 8 , Figure 8 yes Figure 3 The diagram shows a cross-sectional view of an air purifier along the D1-D2 position. In an optional embodiment, the groove wall of the receiving recess c1 has a first opening k4, and the outer shell 111 has a second opening k5 corresponding to the first opening k4. The mounting shell 11 also includes a replacement cover 113. The first opening k4 and the second opening k5 are used for the filter assembly 30 to pass through. The replacement cover 113 is movably mounted at the second opening k5 of the outer shell 111. For example, the replacement cover 113 can be snapped to the outer shell 111 or rotated through a rotating structure, so that the replacement cover 113 can open or close the second opening k5. During the use of the air purifier, the user can open the replacement cover 113 and remove the filter assembly 30 to be replaced from the mounting shell 11 through the first opening k4 and the second opening k5. Then, the filter assembly 30 to be used is sent into the receiving recess c1 of the inner shell 112 through the second opening k5 and the first opening k4, thus simplifying the replacement of the filter assembly 30.

[0065] In one exemplary embodiment, the replacement cover 113 can be a separate structure from the filter assembly 30, or the replacement cover 113 can be fixedly connected to the filter assembly 30, or the replacement cover 113 can be an integral structure with the filter assembly 30.

[0066] Please refer to Figure 2 , Figure 5 and Figure 9 , Figure 9 yes Figure 5 The diagram shows a cross-sectional view of the air purifier along the E1-E2 position. In an optional embodiment, the mounting housing 11 further includes two airflow rectifier grilles 14, which are respectively fixed at the two vents k3. The airflow rectifier grilles 14 can be used to rectify the airflow to reduce non-uniformity and eddies entering the fan assembly 20, thereby improving fan performance and reducing noise. Exemplarily, by rectifying the airflow, the airflow rectifier grilles 14 make the upstream airflow of the fan cleaner, effectively improving aerodynamic performance and reducing noise; in addition, the airflow rectifier grilles 14 can also serve as a motor mounting bracket, providing stable support. In an exemplary embodiment, the airflow rectifier grilles 14 and the inner housing 112 can be fixedly connected by bolts, or the airflow rectifier grilles 14 and the inner housing 112 can be an integral structure.

[0067] Please refer to Figure 9 In one optional embodiment, any one of the rectifier grilles 14 may include multiple rectifier blades 142; the multiple rectifier blades 142 are arranged around the axis of the fan assembly 20, and all the multiple rectifier blades 142 are streamlined. For example, the bending direction of the rectifier blades 142 may be opposite to the rotation direction of the fan. By setting a streamlined rectifier grille 14 at the air inlet of the fan assembly 20, the airflow passing through the rectifier grille 14 can better match the flow state of the fluid before entering the fan assembly 20, forming a pre-swirl effect, reducing the flow loss at the leading edge of the blades in the fan assembly 20, avoiding airflow separation on the suction surface of the blades in the fan assembly 20, which is beneficial to improving the air volume and the efficiency of the fan assembly 20.

[0068] In one exemplary embodiment, any one of the rectifier grilles 14 may also include a central section, with a plurality of rectifier blades 142 arranged around the central section 141 and fixedly connected to the central section 141. The central section 14 can provide installation space for the drive motor in the fan assembly 20.

[0069] Please refer to Figure 6 In an optional embodiment, the inner shell 112 may further include two receiving portions 1121 and two arc-shaped air duct portions 1122. The air purifier also includes two outlet guide structures 40. The two receiving portions 1121 are respectively covered on the outside of the two fan assemblies 20. The two arc-shaped air duct portions 1122 are respectively located between the two fan assemblies 20 and the two side air outlets k2, and one end of any arc-shaped air duct portion 1122 is connected to the receiving portion 1121, and the other end is connected to the side air outlet k2.

[0070] The fan assembly 20 may include a drive motor and a centrifugal impeller. The motor drives the centrifugal impeller to rotate, generating suction to draw airflow axially and radially into the volute. The axis of the fan assembly 20 may be the axis of the centrifugal impeller. In this embodiment, the volute includes a receiving portion 1121 and an arc-shaped air duct portion 1122.

[0071] Two outlet guide structures 40 are respectively installed in two arc-shaped air duct sections 1122. Due to the large back pressure of the fan assembly 20 during operation, the airflow near the volute tongue is prone to backflow. Furthermore, the significant difference in cross-sectional area between the air inlet and outlet of the arc-shaped air duct section 1122 can easily lead to insufficient airflow diffusion, resulting in uneven wind speed distribution. By installing outlet guide structures 40 in the outlet section of the arc-shaped air duct section 1122, the backflow near the volute tongue can be reduced. Simultaneously, the airflow in the arc-shaped air duct section 1122 is slowed and diffused, resulting in a more uniform wind speed at the outlet of the arc-shaped air duct section 1122, thereby reducing noise at the outlet.

[0072] Please refer to Figure 10 , Figure 10 This is a schematic diagram of the internal structure of another air purifier provided in an embodiment of the present invention. In an optional embodiment, any outlet guide structure 40 may include at least one outlet guide vane group 41, and any outlet guide vane group 41 includes at least one outlet guide vane 411. When the outlet guide structure 40 includes multiple outlet guide vane groups 41, the multiple outlet guide vane groups 41 are arranged along the gas flow direction in the arc-shaped air duct 1122, and the number of outlet guide vanes 411 in the multiple outlet guide vane groups 41 gradually increases along the gas flow direction. In this way, by arranging multiple layers of outlet guide vanes 411, the airflow deceleration and diffusion are more sufficient, and the air velocity at the air outlet is more uniform. For example, the difference between the cross-sectional area at the air inlet and the cross-sectional area at the air outlet of the arc-shaped air duct section 1122 can be proportional to the number of outlet guide vane groups. When the difference between the cross-sectional area at the air inlet and the cross-sectional area at the air outlet of the arc-shaped air duct section 1122 is small, one outlet guide vane group can be provided in the arc-shaped air duct section. When the difference between the cross-sectional area at the air inlet and the cross-sectional area at the air outlet of the arc-shaped air duct section 1122 is large, multiple outlet guide vane groups can be provided in the arc-shaped air duct section.

[0073] In one exemplary embodiment, the outlet guide vane 411 may be fixedly connected to the housing 111. For example, the outlet guide vane 411 may be welded or snapped to the housing 111, or the outlet guide vane 411 and the housing 111 may be an integral structure.

[0074] Please refer to Figure 11 , Figure 11This is a schematic diagram of another air purifier provided by an embodiment of the present utility model. In an optional embodiment, the outer shell 111 may have multiple mounting slots c2 on the side opposite to the air guide cover 12. The multiple mounting slots c2 are used to cooperate with the bracket to connect and install the air purifier on the wall.

[0075] The bracket can be fixedly installed on the wall. Multiple mounting slots (c2) can include multiple horizontal slots and multiple vertical slots, allowing the air purifier to be installed in different orientations according to actual needs.

[0076] For example, after the air purifier is installed on the wall, the air outlet direction of the air purifier can be up and down; or, the air outlet direction of the air purifier can be left and right. Users can flexibly adjust the installation method and direction of the air purifier according to the needs of the installation environment. This utility model embodiment does not limit this.

Furthermore, it is understood that when an element is referred to as "on top of" another element, it can be directly on the other element, or there may be intermediate elements. Additionally, it is understood that when an element is referred to as "below" another element, it can be directly below the other element, or there may be more than one intermediate element. Furthermore, it is also understood that when an element is referred to as "between" two elements, it can be the only layer between the two elements, or there may be more than one intermediate element.
