The specific meanings need to be understood in the context.

[0038] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0039] As people's living standards gradually improve, their requirements for indoor building comfort, building energy efficiency, and indoor air quality are also getting higher and higher. Air handling units can regulate and control the quality of indoor air, thereby providing a comfortable and healthy environment for indoor occupants.

[0040] In order to prevent bacteria in the outside air from entering the room, a sterilization device is usually installed in the air handling unit in related technologies. The sterilization device can effectively eliminate bacteria in the outside air, thereby improving the air quality and ensuring the health and safety of the indoor environment.

[0041] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an air handling unit 200 in the related art. Air handling unit 200 may include a housing 010, within which a fresh air duct 011 may be formed. Housing 011 is provided with an air inlet 012 and an air outlet 013, which are connected to both ends of fresh air duct 011, respectively. Thus, outside air can enter fresh air duct 011 through air inlet 012 and enter the room through air outlet 013.

[0042] Continue to refer to Figure 1 The air handling unit 200 may also include a filter 020, a surface cooler 030, a humidifier (not shown in the figure), a dehumidifier 050, a fan 060 and a heater 070. The filter 020, the surface cooler 030, the humidifier, the dehumidifier 050, the fan 060 and the heater 070 may all be arranged inside the casing 010.

[0043] For example, Figure 1As shown, from the air inlet 012 to the air outlet 013, the shell 010 can be sequentially divided into a fresh air section 014, a filtering section 015, a surface cooling section 016, a fan section 017, an equalization section 018, an electric heating section 019, and a supply air section 0110. The fresh air section 014 is provided with the air inlet 012 at one end away from the filtering section 015, and external air can enter the fresh air section 014 from the air inlet 012.

[0044] The filter 020 can be arranged in the filtering section 015, and the filter 020 can remove dust and impurities in the external air when the external air passes through the filtering section 015.

[0045] The surface cooler 030 can be arranged in the surface cooling section 016, and the surface cooler 030 is usually provided with low-temperature cooling medium circulating in the interior after starting to work. When air flows through the surface of the cooler, heat is transferred from the air to the cooling medium, so that the air is cooled. In hot weather, the staff can start the surface cooler 030 to reduce the temperature of the air entering the room.

[0046] The fan 060 can be arranged in the fan section 017, and the fan 060 can drive external air to enter the room along the fresh air channel 011 after starting to work, to provide fresh air for the room. The equalization section 018 can be provided with a flow guide plate or a diffuser and the like, so as to adjust the direction and speed of air flow, and make the air more evenly distributed in the entire pipe cross section.

[0047] The electric heating section 019 is provided with a heater 070 in the interior, and the heater 070 can heat the air passing through the surface of the heater 070 after starting to work. In this way, in cold weather, the staff can start the heater 070 to heat the air entering the room, so as to keep the indoor temperature in a suitable range.

[0048] In order to ensure the cleanliness of the air entering the room, in the related art, for example, Figure 1 As shown, the air handling unit 200 usually further includes a sterilization device 080. The sterilization device 080 usually includes an ultraviolet sterilization lamp, and light emitted by the ultraviolet sterilization lamp can penetrate the cell wall of microorganisms, damage the DNA structure in the interior, and cause the microorganisms to be unable to reproduce and grow, so as to achieve the effect of inactivation, and the ultraviolet sterilization lamp has good killing effect on various bacteria, viruses and even part of fungi.

[0049] In the existing air handling unit, the ultraviolet sterilization lamp is usually directly installed on the inner wall of the shell 010 of the air handling unit 020, and the shell 010 has poor protection effect on the ultraviolet sterilization lamp, and the ultraviolet sterilization lamp is easy to be damaged in the process of transportation.

[0050] Based on this, the embodiment of the present application provides an air handling unit, as shown in Figure 2 As shown,Figure 2 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100.

[0051] As shown in Figure 3 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100. Figure 3 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100.

[0052] In actual applications, the air inlet 12 is usually arranged outdoors, and the air outlet 13 is usually arranged indoors. Air from the outside can enter the fresh air channel 11 from the air inlet 12 and be discharged into the room from the air outlet 13.

[0053] It can be understood that, in actual applications, the air handling unit 100 can include filters, surface coolers, humidifiers, dehumidifiers, fans, and heaters, etc. to achieve the basic functions of the air handling unit 100.

[0054] In order to purify the air entering the room, in some embodiments, as shown in Figure 4 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100. Figure 4 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100.

[0055] In some embodiments, as shown in Figure 4 A structure diagram of an air handling unit 100 is provided in some embodiments. The air handling unit 100 can include a housing 1. In actual applications, the components of the air handling unit 100 can be arranged inside the housing 1, and the housing 1 can provide protection for the components of the air handling unit 100.

[0056] In actual applications, since the containment cavity 811 is formed inside the protective member 81 and the sterilization member 82 is arranged inside the containment cavity 811, the protective member 81 can protect the sterilization member 82 inside the containment cavity 811, thereby reducing damage to the sterilization member 82 during transportation.

[0057] It can be understood that the sterilization assembly 8 can form a separate module, and the staff can set different numbers of sterilization assemblies 8 according to the size of the section of the fresh air channel 11, and each sterilization assembly 8 is independent of each other. In this way, when a certain sterilization assembly 8 is damaged, the staff can quickly replace the damaged part, improving the maintenance efficiency.

[0058] Moreover, compared with the traditional setting form, the sterilization assembly 8 of the application divides the sterilization unit of the air handling unit into multiple independent individuals, and during transportation, the staff can protect each independent unit, i.e., the single sterilization assembly 8, separately, and the sterilization assembly 8 is not easy to be damaged during transportation.

[0059] Since the protection piece 81 is provided with the first inlet 812 and the first outlet 813 which are in communication with the containing cavity 811, the air entering the fresh air channel 11 can pass through the containing cavity 811. In this way, the sterilization piece 82 located in the containing cavity 811 can sterilize the air passing through the containing cavity 811.

[0060] For example, the sterilization piece 82 can be an ultraviolet sterilization lamp, which is arranged in the containing cavity 811 and can emit ultraviolet rays after being powered on, thereby sterilizing the air passing through the containing cavity 811.

[0061] In order to ensure the sterilization effect, in some embodiments, as shown in Figure 5 , Figure 5 For the structure schematic view of the sterilization assembly 8 provided by the embodiments of the application, the number of sterilization pieces 82 can be multiple. In this way, multiple sterilization pieces 82 can be arranged at different positions in the containing cavity 811, thereby ensuring the sterilization effect of the sterilization piece 82 on the air in the containing cavity 811.

[0062] In order to facilitate the disassembly and installation of multiple sterilization pieces 82, in some embodiments, as shown in Figure 6 , Figure 6 For the structure schematic view of the sterilization assembly 8 provided by the embodiments of the application, the sterilization assembly 8 can also include a mounting piece 83. The mounting piece 83 is arranged in the containing cavity 811 and is detachably connected with the protection piece 81, and multiple sterilization pieces 82 are mounted on the mounting piece 83.

[0063] Since multiple sterilization pieces 82 are mounted on the mounting piece 83, and the mounting piece 83 is detachably connected with the protection piece 81, when it is necessary to repair and replace the sterilization piece 82, the staff can detach the mounting piece 83 from the protection piece 81, so as to take out the mounting piece 83 together with the sterilization piece 82 from the containing cavity 811. After the mounting piece 83 is taken out from the containing cavity 811, the protection piece 81 will not interfere with the maintenance work of the staff, and the staff can detach the sterilization piece 82 from the protection piece 81.

[0064] To realize the detachable connection between the mounting member 83 and the protection member 81, in some embodiments, as shown in Figure 6 the accommodating cavity 811 extends along the first direction X, and two ends are formed with a first inlet 812 and a first outlet 813.

[0065] As shown in Figure 7 , Figure 7 Figure 3 is a third structure diagram of the sterilization assembly 8 provided by the embodiments of the present application, and the sterilization assembly 8 can further include a plurality of limiting members 84. Along the first direction X, the plurality of limiting members 84 are respectively arranged at two ends of the protection member 81 and movably connected with the protection member 81.

[0066] At least a part of the plurality of limiting members 84 is used to move to a part of the first inlet 812 and oppositely arranged with the mounting member 83 to limit the mounting member 83 from sliding out. In this way, when a part of the plurality of limiting members 84 moves to a part of the first inlet 812, the mounting member 83 can be limited to slide out of the accommodating cavity 811 from the first inlet 812. Figure 6 ).

[0067] As shown in Figure 8 , Figure 8 Figure 4 is a fourth structure diagram of the sterilization assembly 8 provided by the embodiments of the present application, and at least a part of the plurality of limiting members 84 is used to move to a part of the first outlet 813 and oppositely arranged with the mounting member 83 to limit the mounting member 83 from sliding out. In this way, when a part of the plurality of limiting members 84 moves to a part of the first outlet 813, the mounting member 83 can be limited to slide out of the protection member 81 from the first outlet 813.

[0068] According to the above, the plurality of limiting members 84 can respectively limit the mounting member 83 from sliding out of the accommodating cavity 811 from the first inlet 812 and the first outlet 813, so as to fix the mounting member 83 in the accommodating cavity 811.

[0069] In some embodiments, the plurality of limiting members 84 is also used to move to avoid the first inlet 812 and the first outlet 813. In this way, the plurality of limiting members 84 no longer limits the mounting member 83 from sliding, and the mounting member 83 can slide out of the accommodating cavity 811 from the first inlet 812 or the first outlet 813.

[0070] In some embodiments, as shown in Figure 7 and Figure 8As shown, the plurality of limiting members 84 are rotatably connected with the protection member 81. In this way, the staff can rotate the plurality of limiting members 84, so as to change the positions of the plurality of limiting members 84, facilitating the staff to move the plurality of limiting members 84 to positions shielding the first inlet 812 or the first outlet 813, so as to limit the installation member 83 from sliding out of the accommodating cavity 811, or to move the limiting members 84 to positions avoiding the first inlet 812 or the first outlet 813, so as to enable the installation member 83 to be taken out of the accommodating cavity 811.

[0071] In some embodiments, as shown in Figure 9 Figure 9 For the fifth structural schematic diagram of the sterilization assembly 8 provided by the embodiments of the present application, the installation member 83 can include a first installation member 831 and a second installation member 832. The second installation member 832 is oppositely arranged with the first installation member 831, one end of the plurality of sterilization members 82 is connected with the first installation member 831, and the other end is connected with the second installation member 832. In this way, the first installation member 831 and the second installation member 832 can support the two ends of the sterilization members 82, so as to fix the positions of the sterilization members 82.

[0072] In some embodiments, as shown in Figure 10 Figure 10 For the sixth structural schematic diagram of the sterilization assembly 8 provided by the embodiments of the present application, the first installation member 831 is formed with a first opening 8311, and the first opening 8311 is in communication with the accommodating cavity 811. As shown in Figure 11 Figure 11 For the seventh structural schematic diagram of the sterilization assembly 8 provided by the embodiments of the present application, the second installation member 832 is formed with a second opening 8321, and the second opening 8321 is in communication with the accommodating cavity 811.

[0073] In actual application, the arrangement of the first opening 8311 and the second opening 8321 can reduce the obstruction of the first installation member 831 and the second installation member 832 to the air passing through the accommodating cavity 811, and the external air can smoothly pass through the accommodating cavity 811.

[0074] As shown in Figure 9 The installation member 83 can further include a connecting member 833, one end of the connecting member 833 is connected with the first installation member 831, and the other end is connected with the second installation member 832. In this way, the connecting member 833 can support the first installation member 831 and the second installation member 832, so as to keep the first installation member 831 and the second installation member 832 at a fixed distance, avoiding the first installation member 831 and the second installation member 832 from pressing the sterilization members 82.

[0075] In order to reduce the dust entering the accommodating cavity 811, in some embodiments, as shown in Figure 10 ​​​As shown, the peripheral wall of the first mounting member 831 abuts against the inner wall of the accommodating cavity 811. In this way, the first mounting member 831 can block one end of the accommodating cavity 811, and air can only pass through the first opening 8311.

[0076] like Figure 12 As shown, Figure 12 This is the eighth structural diagram of the sterilization component 8 provided in the embodiment of the present application. The sterilization component 8 may further include a first filter 85. The first filter 85 is connected to the first mounting member 831 and is located away from the second mounting member 832 ( Figure 11 ), the first filter screen 85 covers the first opening 8311.

[0077] In actual use, the sterilization element 82 is located between the first mounting member 831 and the second mounting member 832. When outside air passes through the accommodating chamber 811 in the direction from the first mounting member 831 to the second mounting member 832, the outside air is first filtered by the first filter 85 before coming into contact with the sterilization element 82. This removes dust and impurities remaining in the outside air, preventing them from affecting the sterilization element 82.

[0078] In some embodiments, as Figure 11 The peripheral wall of the second mounting member 832 is in contact with the inner wall of the accommodating cavity 811. In this way, the second mounting member 832 can block the outlet of the accommodating cavity 811 away from the end of the first mounting member 831, and air can only pass through the second opening 8321.

[0079] like Figure 13 As shown, Figure 13 This is the ninth structural diagram of the sterilization assembly 8 provided in an embodiment of the present application. The sterilization assembly 8 may further include a second filter 86. The second filter 86 is connected to the second mounting member 832 and is located on a side of the second mounting member 832 away from the first mounting member 831. The second filter 86 covers the second opening 8321.

[0080] During actual application, the sterilization component 82 is located between the first mounting component 831 and the second mounting component 832. When the outside air passes through the accommodating cavity 811 along the direction from the first mounting component 831 to the second mounting component 832, the second filter 86 can intercept some harmful substances entering the accommodating cavity 811 between the first mounting component 831 and the second mounting component 832, thereby increasing the duration of the sterilization component 82's action on the harmful substances to ensure the cleanliness of the air entering the room.

[0081] For example, the sterilization member 82 can be an ultraviolet sterilization lamp, the first mounting member 831 can be located at one end of the protection member 81 close to the air inlet 12, and the second mounting member 832 can be located at one end of the protection member 81 close to the air outlet 13. In this way, the first filter screen 85 can remove dust and impurities in the external air, preventing dust and impurities from entering the containing cavity 811 and accumulating on the surface of the sterilization member 82. The second filter screen 86 can block the air in the containing cavity 811, increasing the time length of harmful substances in the air in the containing cavity 811, thereby ensuring the sterilization effect of the sterilization member 82 on the air.

[0082] In some embodiments, as shown in Figure 12 A first containing groove 8312 can be formed at the first opening 8311, and the first containing groove 8312 is arranged around the first opening 8311. The first filter screen 85 is inserted into the first containing groove 8312, and the first containing groove 8312 can provide a setting position for the first filter screen 85.

[0083] It can be understood that when part of the limiting member 84 is rotated to a position that partially shields the first inlet 812, the limiting member 84 can simultaneously abut against the first mounting member 831 and the first filter screen 85. In this way, the limiting member 84 can also limit the first filter screen 85 from being separated from the first containing groove 8312.

[0084] When the limiting member 84 is rotated to a position that avoids the first inlet 812, the worker can take out the first filter screen 85 from the first containing groove 8312, facilitating the worker to replace the first filter screen 85.

[0085] In some embodiments, as shown in Figure 13 A second containing groove 8322 can be formed at the second opening 8321, and the second containing groove 8322 is arranged around the second opening 8321. The second filter screen 86 is inserted into the second containing groove 8322, and the second containing groove 8322 can provide a setting position for the second filter screen 86.

[0086] It can be understood that when part of the limiting member 84 is rotated to a position that partially shields the first outlet 813, the limiting member 84 can simultaneously abut against the second mounting member 832 and the second filter screen 86. In this way, the limiting member 84 can also limit the second filter screen 86 from being separated from the second containing groove 8322.

[0087] When the limiting member 84 is rotated to a position that avoids the first outlet 813, the worker can take out the second filter screen 86 from the second containing groove 8322, facilitating the worker to replace the second filter screen 86.

[0088] In some embodiments, as shown in Figure 12As shown, the mounting member 83 may further include a first mounting portion 834 connected to the first mounting member 831. The first mounting portion 834 is disposed in the first opening 8311, partially shielding the first opening 8311.

[0089] like Figure 13 As shown, the mounting member 83 may further include a second mounting portion 835, which is disposed in the second opening 8321, partially blocking the second opening 8321, and interlocking with the first mounting portion 834 ( Figure 12 ) relative settings.

[0090] The two ends of the plurality of sterilization elements 82 are respectively connected to the first mounting portion 834 and the second mounting portion 835. In this way, the connection between the first mounting portion 834 and the second mounting portion 835 can provide a mounting position for the plurality of sterilization elements 82.

[0091] For example, Figure 13 as well as Figure 12 As shown, the first mounting portion 834 and the second mounting portion 835 can be connected by interwoven mounting rods 836, and a clamping portion 837 is formed at the intersection of the mounting rods 836. The two ends of the sterilization element 82 can be respectively clamped into the clamping portions 837 formed on the first mounting portion 834 located in the first opening 8311 and the second opening 8321.

[0092] Because the first mounting portion 834 and the second mounting portion 835 are composed of interwoven mounting rods 836, resistance to air flow is reduced, facilitating air flow through the first opening 8311 and the second opening 8321. Because both ends of the sterilization element 82 are engaged within the engaging portions 837 formed on the first mounting portion 834 and the second mounting portion 835 within the first opening 8311 and the second opening 8321, it is easy for personnel to remove the sterilization element 82 from the mounting member 83.

[0093] In order to reduce the noise of the air handling unit 100, in some embodiments, as Figure 14 As shown, Figure 14 The tenth structural diagram of the sterilization assembly 8 provided in the embodiment of the present application, the protective member 81 includes a sound-absorbing layer 814 and a protective layer 815. The sound-absorbing layer 814 has an accommodating cavity 811 formed therein and a first inlet 812 ( Figure 6 ) and the first outlet 813( Figure 6 ).

[0094] In actual application, the sound-absorbing layer 814 can be made of a sound-absorbing material. In this way, the sound-absorbing layer 814 can weaken the transmission of sound, thereby reducing the sound transmitted from the accommodating cavity 811 to the outside, thereby reducing the air handling unit 100 ( Figure 2 )

[0095] The protective layer 815 is located on a side of the sound-absorbing layer 814 away from the accommodating cavity 811 and is disposed around the peripheral wall of the sound-absorbing layer 814. In this way, the protective layer 815 can wrap up the sound-absorbing layer 814, thereby protecting the sound-absorbing layer 814.

[0096] In some embodiments, as Figure 14 As shown, the sound-absorbing layer 814 includes an inner protective layer 8141 and a porous sound-absorbing layer 8142. The inner protective layer 8141 is formed with a receiving cavity 811 and a first inlet 812 ( Figure 6 ) and the first outlet 813( Figure 6 ).

[0097] The porous sound-absorbing layer 8142 is located on the side of the inner protective layer 8141 away from the accommodating cavity 811 and is disposed around the peripheral wall of the inner protective layer 8141. The protective layer 815 is located on the side of the porous sound-absorbing layer 8142 away from the accommodating cavity 811 and is disposed around the peripheral wall of the porous sound-absorbing layer 8142. Thus, the porous sound-absorbing layer 8142 is sandwiched between the inner protective layer 8141 and the protective layer 815, and the inner protective layer 8141 and the protective layer 815 can effectively protect the porous sound-absorbing layer 8142.

[0098] For example, the porous sound-absorbing layer 8142 can be a sound-absorbing cotton layer. The sound-absorbing cotton contains a large number of tiny pores. When sound waves pass through these pores, the sound wave energy is converted into heat and dissipated. At the same time, the presence of these pores causes air molecules to vibrate within the pores, thereby consuming the energy of the sound waves. It is understood that the porous sound-absorbing layer 8142 can also be made of other materials, as long as they can effectively reduce the transmission of sound. For example, the porous sound-absorbing layer 8142 can also be a foam sound-absorbing board.

[0099] In some embodiments, the inner protective layer 8141 may be provided with a plurality of muffler holes 8143. After the sound waves enter the muffler holes 8143, they are reflected and refracted inside the muffler holes 8143. Multiple reflections will cause the energy of the sound waves to gradually dissipate, thereby achieving a sound-absorbing effect.

[0100] In order to improve the sterilization effect of the sterilization component 8, in some embodiments, the surface of the inner protective layer 8141 close to the accommodating cavity 811 can be coated with a reflective material. The reflective material can improve the reflection of ultraviolet rays by the inner protective layer 8141, thereby improving the sterilization effect of the sterilization component 8 on the air in the accommodating cavity 811.

[0101] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any change or replacement within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
