Technical Field

[0001] The present application belongs to the field of electrical appliance technology, and specifically relates to a fresh air module and an air conditioner. Background Art

[0002] The fresh air module is connected to the outside through a fresh air duct passing through a wall hole to draw fresh air from outside into the room to improve the indoor air quality. In order to filter the outdoor fresh air, a filter component will be set in the fresh air module.

[0003] However, in the prior art, air leakage is likely to occur between the filter assembly and the housing of the fresh air module, thus affecting the air volume. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a fresh air module and an air conditioner, which aim to at least solve the technical problem of air leakage between the filter assembly and the shell of the fresh air module, thereby affecting the air volume.

[0005] The technical solution of the utility model is:

[0006] A fresh air module is special in that it includes: a shell, which is provided with an installation opening and a accommodating cavity, and is provided with an air inlet and an air outlet; a fan assembly, which is arranged in the accommodating cavity; a filter assembly, which is passed through the installation opening and installed in the accommodating cavity, and is located between the air inlet and the air outlet; a first sealing member, which is sleeved on the filter assembly and is used to seal the gap between the filter assembly and the installation opening.

[0007] Since the shell is provided with an installation opening and a accommodating cavity, and is provided with an air inlet and an air outlet, the fan assembly is arranged in the accommodating cavity. Therefore, when fresh air is to be introduced, the fan assembly is driven, and the outdoor fresh air enters the room through the air inlet and the air outlet, so that fresh air from the outdoor can be introduced into the room, thereby improving the indoor air quality and user comfort. Since the filter assembly is installed in the accommodating cavity through the installation opening and is located between the air inlet and the air outlet, when fresh air is to be introduced, the filter assembly can filter the fresh air to remove particulate matter in the outdoor fresh air, thereby further improving the indoor air quality and user comfort. Since the first sealing member is sleeved on the filter assembly and is used to seal the gap between the filter assembly and the installation opening, the first sealing member can seal the gap between the filter assembly and the installation opening, thereby effectively preventing the airflow in the accommodating cavity from leaking or cross-flowing through the gap between the filter assembly and the installation opening, thereby avoiding abnormal noise, ensuring air volume, and improving user experience. At the same time, it can also prevent external impurities from entering the accommodating cavity through the gap between the filter assembly and the installation opening, thereby ensuring the safety of the equipment in the accommodating cavity.

[0008] In some embodiments, the first sealing member is at least partially located within the installation opening to ensure a sealing effect of the first sealing member.

[0009] In some embodiments, the filter assembly includes: a support seat; a support frame connected to the support seat; a filter element, arranged in the support frame and located in the accommodating cavity; wherein the first sealing element is sleeved on the support seat to ensure the sealing effect of the first sealing element.

[0010] In some embodiments, the fresh air module also includes: a limiting ring, connected to the shell and arranged in the installation port; wherein the first sealing component is partially arranged between the limiting ring and the support seat to further ensure the sealing effect of the first sealing component.

[0011] In some embodiments, the fresh air module further includes: a protective member connected to the shell and located outside the accommodating cavity; wherein the support seat is at least partially located inside the protective member to ensure the safety of the support seat.

[0012] In some embodiments, the fresh air module also includes: two second seals, which are located on both sides of the filter assembly, between the filter assembly and the inner wall of the accommodating cavity, and extend away from the installation port to achieve sealing between the filter assembly and the inner wall of the accommodating cavity.

[0013] In some embodiments, the fresh air module further includes: a third seal located between the filter assembly and the inner wall of the accommodating cavity; wherein the third seal is arranged opposite to the first seal to achieve sealing between the filter assembly and the inner wall of the accommodating cavity.

[0014] In some embodiments, one of the filter assembly and the housing is provided with a buckle, and the other is provided with a slot, and the buckle can be locked in the slot to facilitate connection between the filter assembly and the housing.

[0015] In some embodiments, the filter assembly is tilted in the accommodating cavity to ensure the purification effect of the filter assembly.

[0016] Based on the same utility model concept, the utility model also provides an air conditioner, including the fresh air module. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0040] The fresh air module and air conditioner provided in this embodiment are intended to at least to some extent solve the technical problem of air leakage between the filter assembly and the housing of the fresh air module, which affects the air volume.

[0041] Figure 1 Schematic diagram of the structure of the fresh air module in some embodiments; Figure 2 for Figure 1 Cross-sectional view of the fresh air module; Figure 3 for Figure 1 Schematic diagram of the installation of the filter components of the fresh air module; Figure 4 for Figure 3Cross-sectional view of the fresh air module. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The fresh air module of the embodiment of the present application includes: a shell 10, a fan assembly 20, a filter assembly 30 and a first sealing member 40. The shell 10 is provided with an installation opening 101 and a receiving cavity 102, and is provided with an air inlet 103 and an air outlet 104. The fan assembly 20 is arranged in the receiving cavity 102. The filter assembly 30 is passed through the installation opening 101 and installed in the receiving cavity 102, and is located between the air inlet 103 and the air outlet 104. The first sealing member 40 is sleeved on the filter assembly 30 and is used to seal the gap between the filter assembly 30 and the installation opening 101.

[0042] The installation opening 101 , the air inlet 103 and the air outlet 104 are all in communication with the accommodating cavity 102 .

[0043] The installation opening 101 is located between the air inlet 103 and the air outlet 104 .

[0044] The first sealing member 40 may be a rubber sealing ring.

[0045] Since the shell 10 is provided with an installation port 101 and a receiving cavity 102, and is provided with an air inlet 103 and an air outlet 104, the fan assembly 20 is arranged in the receiving cavity 102, so when fresh air is to be taken in, the fan assembly 20 is driven, and the outdoor fresh air enters the room through the air inlet 103 and the air outlet 104, so that outdoor fresh air can enter the room, improve the indoor air quality, and improve the user comfort. Since the filter assembly 30 is provided through the installation port 101 and installed in the receiving cavity 102, and is located between the air inlet 103 and the air outlet 104, when fresh air is to be taken in, the filter assembly 30 can filter the fresh air to remove particulate matter in the outdoor fresh air, further Indoor air quality is improved step by step, and user comfort is improved. Since the first sealing member 40 is sleeved on the filter assembly 30 and is used to seal the gap between the filter assembly 30 and the installation port 101, the first sealing member 40 can seal the gap between the filter assembly 30 and the installation port 101, and can effectively prevent the airflow in the accommodating chamber 102 from leaking or flowing through the gap between the filter assembly 30 and the installation port 101, thereby avoiding abnormal noise, ensuring air volume, and improving the user experience. At the same time, it can also prevent external impurities from entering the accommodating chamber 102 through the gap between the filter assembly 30 and the installation port 101, thereby ensuring the safety of the equipment in the accommodating chamber 102.

[0046] In some embodiments, since the first seal 40 can seal the gap between the filter assembly 30 and the installation port 101, if the temperature difference between indoor and outdoor is large, condensation water appears in the accommodating cavity 102, the condensation water can be prevented from dripping into the room through the gap between the filter assembly 30 and the installation port 101, thereby improving the user experience.

[0047] Figure 5 for Figure 1 Installation diagram of the filter assembly of the fresh air module; Figure 6 for Figure 5 A magnified diagram of the fresh air module. Figure 5 and Figure 6 In some embodiments, in order to ensure the sealing effect of the first seal 40, the first seal 40 is at least partially located in the installation port 101, and the first seal 40 is limited by the inner wall of the installation port 101 to form a tight and stable sealing interface, thereby ensuring the stability of the gap between the sealing filter assembly 30 and the installation port 101.

[0048] In some embodiments, the first seal 40 can be entirely located within the installation opening 101 , and the first seal 40 can be shielded by the inner wall of the installation opening 101 to prevent the first seal 40 from being exposed to the outside, thereby ensuring the safety of the first seal 40 and ensuring aesthetics.

[0049] Combine Figure 5 and Figure 6 In some embodiments, to ensure the sealing effect of the first sealing member 40, the filter assembly 30 includes: a support base 301, a support frame 302, and a filter element 303. The support frame 302 is connected to the support base 301. The filter element 303 is disposed within the support frame 302 and is located within the accommodating cavity 102. The first sealing member 40 is sleeved on the support base 301.

[0050] In some embodiments, when the filter assembly 30 is installed in the accommodating cavity 102, the support frame 302 enters the accommodating cavity 102 through the installation port 101, and the support seat 301 can apply pressure to the first seal 40 to ensure that the contact between the first seal 40 and the installation port 101, the support seat 301 and the support frame 302 is closer, reducing or eliminating potential gaps, thereby improving the sealing effect and preventing gas leakage. Moreover, by directly applying pressure to the first seal 40 through the support seat 301, no additional tools or steps are required to ensure the correct installation and sealing of the first seal 40, which simplifies the installation process, reduces the difficulty of installation, and reduces the risk of sealing failure due to improper installation.

[0051] In some embodiments, the support seat 301 can be integrally formed with the support frame 302, so that there are no additional connectors or seams between the support seat 301 and the support frame 302, thereby reducing potential weaknesses and ensuring the structural strength of the filter assembly 30. Moreover, during the manufacturing process, the one-piece molding can ensure precise alignment and fit between the support seat 301 and the support frame 302, reducing the risk of performance degradation or failure due to assembly errors, improving accuracy and reliability, and at the same time, simplifying the manufacturing process, reducing the assembly steps and the number of parts required, and reducing production costs and manufacturing cycles.

[0052] Combine Figure 5 and Figure 6 In some embodiments, to further ensure the sealing effect of the first sealing member 40, the fresh air module further includes a retaining ring 50. The retaining ring 50 is connected to the housing 10 and disposed within the mounting opening 101. Part of the first sealing member 40 is disposed between the retaining ring 50 and the support seat 301.

[0053] In some embodiments, when the filter assembly 30 is installed in the accommodating cavity 102, the support frame 302 enters the accommodating cavity 102 through the installation port 101 and the limiting ring 50, and the support seat 301 can interfere with the first seal 40, applying pressure to the first seal 40 so that the first seal 40 is squeezed between the support seat 301 and the limiting ring 50, forming a tight and uniform sealing interface, reducing the gap between the first seal 40 and the limiting ring 50, the support seat 301 and the installation port 101, enhancing the elastic deformation ability of the first seal 40, thereby improving the sealing performance and effectively preventing leakage. At the same time, the limiting ring 50 can support the support seat 301 to achieve the limitation of the support seat 301, which can ensure that the support seat 301 can accurately reach the predetermined position during the installation process, reduce the risk of sealing performance degradation or failure due to installation errors, improve the installation accuracy and sealing performance, ensure the accurate installation position of the support seat 301, and ensure the stability of the position of the support seat 301 after installation, which can reduce the movement or deformation of the support seat 301 caused by vibration, impact or external force, thereby enhancing the structural stability of the entire filter assembly 30.

[0054] In some embodiments, the operator only needs to align the support frame 302 with the installation opening 101 and, guided by the retaining ring 50, push it into the accommodating cavity 102. During this process, the support base 301 naturally contacts and applies pressure to the first sealing member 40, so that the first sealing member 40 is pressed against the retaining ring 50. The seal can be installed and sealed without any additional operation or tools, which reduces the difficulty of installation and improves installation efficiency.

[0055] In some embodiments, to ensure that the support frame 302 enters the accommodating cavity 102 through the installation opening 101 and the limiting ring 50 , the area of ​​the end surface of the support frame 302 facing away from the support seat 301 is less than or equal to the area of ​​the inner circle of the limiting ring 50 .

[0056] In some embodiments, in order to ensure that the support seat 301 can press the first seal 40 onto the limiting ring 50, the area of ​​the end of the support seat 301 facing the support frame 302 is larger than the area of ​​the end of the support frame 302 facing the support seat 301. Along the installation direction of the filter assembly 30, the projection of the limiting ring 50 on the shell 10 at least partially overlaps with the projection of the support seat 301 on the shell 10, so that the limiting ring 50 can support the support seat 301.

[0057] In some embodiments, the limit ring 50 can be integrally formed with the shell 10, so that there are no additional connectors or seams between the limit ring 50 and the shell 10, thereby reducing potential weaknesses and ensuring structural strength. Moreover, during the manufacturing process, one-piece molding can ensure precise alignment and fit between the limit ring 50 and the shell 10, reducing the risk of performance degradation or failure due to assembly errors, improving accuracy and reliability, and at the same time, simplifying the manufacturing process, reducing the assembly steps and the number of parts required, and reducing production costs and manufacturing cycles.

[0058] Combine Figure 5 and Figure 6 In some embodiments, to ensure the safety of the support base 301, the fresh air module further includes a protective member 60. The protective member 60 is connected to the housing 10 and is located outside the accommodating cavity 102. The support base 301 is at least partially located within the protective member 60. The protective member 60 provides an additional physical barrier for the support base 301, preventing external objects or environmental factors from colliding with the support base 301. This reduces performance degradation or failures caused by accidental damage and extends the service life of the filter assembly 30.

[0059] In some embodiments, to facilitate the transport and installation of the filter assembly 30, a gripping groove 305 is provided on the end surface of the support base 301 facing away from the support frame 302. The presence of the gripping groove 305 provides the operator with a clear and comfortable gripping point. When the entire filter assembly 30 needs to be transported, the operator can easily apply force through the gripping groove 305, thereby moving the equipment more stably and efficiently, reducing instability during transportation and reducing the risk of accidental dropping or damage. When installing the filter assembly 30, the operator can use the gripping groove 305 to stably operate the support base 301, making it easier to align the filter assembly 30 with the installation port 101 and install it in the designated position, reducing the difficulty and complexity of the installation process and improving installation efficiency.

[0060] Figure 7 for Figure 1 Schematic diagram of the structure of the filter component of the fresh air module. Figure 1 and Figure 7 In some embodiments, in order to achieve a seal between the filter assembly 30 and the inner wall of the accommodating chamber 102, the fresh air module further includes two second seals 70. The two second seals 70 are respectively located on both sides of the filter assembly 30, and between the filter assembly 30 and the inner wall of the accommodating chamber 102, and extend in a direction away from the installation opening 101, forming a sealed barrier that can effectively prevent unfiltered air from bypassing the filter assembly 30 and directly entering the interior of the fresh air module, thereby improving the air purification effect and the overall performance of the system. At the same time, the second seals 70 can cover all potential gaps between the filter assembly 30 and the inner wall of the accommodating chamber 102, ensuring no air leakage and ensuring smooth ventilation.

[0061] In some embodiments, to achieve sealing, the second sealing member 70 includes a first sealing portion 701 and a second sealing portion. The first sealing portion 701 is connected to the filter assembly 30, and the second sealing portion is connected to the inner wall of the accommodating chamber 102. One of the first sealing portion 701 and the second sealing portion is provided with a first sliding groove, and the other is slidably disposed within the first sliding groove to form a sealed barrier, which can effectively prevent unfiltered air from bypassing the filter assembly 30 and directly entering the interior of the fresh air module, thereby improving the air purification effect and the overall performance of the system.

[0062] In some embodiments, one of the first sealing portion 701 and the second sealing portion is provided with a first slide groove, and the other is slidably arranged in the first slide groove, which can guide the installation of the filter component 30 in the accommodating cavity 102. The operator can more easily install the filter component 30 in the accommodating cavity 102 without the need for complicated adjustment or alignment steps, thereby simplifying the installation process and improving installation efficiency.

[0063] Figure 8 for Figure 7 Bottom view of the filter assembly. Figure 1 and Figure 8 In some embodiments, in order to achieve a seal between the filter assembly 30 and the inner wall of the accommodating chamber 102, the fresh air module further includes a third seal 80. The third seal 80 is located between the filter assembly 30 and the inner wall of the accommodating chamber 102. The third seal 80 is arranged opposite to the first seal 40, which can effectively prevent unfiltered air from bypassing the filter assembly 30 and directly entering the interior of the fresh air module, thereby improving the air purification effect and the overall performance of the system. At the same time, the third seal 80 can cover all potential gaps between the filter assembly 30 and the inner wall of the accommodating chamber 102, ensuring no air leakage and ensuring smooth ventilation.

[0064] In some embodiments, to achieve sealing, the third sealing member 80 includes a third sealing portion 801 and a fourth sealing portion. The third sealing portion 801 is connected to the filter assembly 30, and the fourth sealing portion is connected to the inner wall of the accommodating chamber 102. One of the third sealing portion 801 and the fourth sealing portion is provided with a second slide groove, and the other is slidably disposed within the second slide groove to form a sealed barrier, which can effectively prevent unfiltered air from bypassing the filter assembly 30 and directly entering the interior of the fresh air module, thereby improving the air purification effect and the overall performance of the system.

[0065] Combine Figure 5 In some embodiments, in order to facilitate the connection between the filter assembly 30 and the shell 10, one of the filter assembly 30 and the shell 10 is provided with a buckle 304, and the other is provided with a slot 105. The buckle 304 can be locked in the slot 105. The operator only needs to align the buckle 304 with the slot 105 and press it lightly to complete the connection without using additional tools or complicated operating steps. Moreover, it can ensure that the filter assembly 30 can be accurately positioned at the predetermined position during the installation process, thereby ensuring the installation accuracy of the filter assembly 30.

[0066] In some embodiments, when the buckle 304 is engaged with the slot 105, a secure connection is formed between the buckle 304 and the wall of the slot 105, capable of withstanding certain tensile and shear forces. This effectively prevents the filter assembly 30 from loosening or falling off due to vibration or external forces during use, thereby ensuring the stability of the connection between the filter assembly 30 and the housing 10. Furthermore, compared to traditional screw fastening methods, the connection between the buckle 304 and the slot 105 makes disassembly and maintenance of the filter assembly 30 much easier. Operators only need to lift the filter assembly 30 to separate the buckle 304 from the slot 105, and then remove the filter assembly 30 from the housing for cleaning, replacement, or repair, making disassembly and maintenance easier.

[0067] In some embodiments, the filter assembly 30 may be provided with a buckle 304, and the housing 10 may be provided with a slot 105. In this case, the buckle 304 is provided on the support frame 302 of the filter assembly 30. Of course, in other embodiments, the housing 10 may be provided with a buckle 304, and the filter assembly 30 may be provided with a slot 105.

[0068] In some embodiments, in order to ensure the safety of the fan assembly 20, the filter assembly 30 is located between the air inlet 103 and the fan assembly 20. The filter assembly 30 can effectively intercept impurities such as dust, particulate matter, hair, etc. in the air, and can prevent impurities from reaching the fan assembly 20, thereby reducing the risk of contamination and damage to the fan assembly 20 and ensuring the service life of the fan assembly 20.

[0069] In some embodiments, in order to ensure the purification effect of the filter assembly 30, the filter assembly 30 is tilted in the accommodating cavity 102 so that there is a predetermined angle between the filter surface of the filter assembly 30 and the gas flow cross-section. That is to say, the filter surface of the filter assembly 30 is not perpendicular to the airflow direction, and forms a certain angle. In this way, without increasing the external dimensions of the existing equipment, the ventilation area of ​​the filter surface can be effectively increased to ensure the filtering effect. Similarly, under the premise of achieving the same ventilation volume, the wind resistance can be reduced accordingly, and the functional parameters of the fresh air module can be improved.
