Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] As people's living standards improve, their demands for indoor air quality are also increasing. Air conditioners, as crucial devices for regulating indoor temperature and humidity, are prone to harboring bacteria, mold, and other microorganisms, affecting indoor air quality and human health. To address this issue, a technological solution has emerged: incorporating ultraviolet (UV) sterilization modules into the indoor unit of air conditioners. These modules emit ultraviolet light, effectively killing bacteria, viruses, and other microorganisms in the circulating air inside the air conditioner, thus improving indoor air quality.

[0003] However, the ultraviolet (UV) sterilization module in the indoor unit of an air conditioner poses certain safety hazards. Specifically, when users or repair personnel remove the filter for cleaning and maintenance, if the UV sterilization module is still operational, they may be directly exposed to high-intensity UV radiation. UV radiation is highly harmful to human skin and eyes; prolonged or high-intensity UV exposure can lead to skin burns, eye damage, and even increase the risk of skin cancer. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the related technologies, this application provides an air conditioner indoor unit to solve the problem that the ultraviolet sterilization module is still in working condition when users or maintenance personnel are cleaning and maintaining it.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides an air conditioner indoor unit, which includes:

[0006] The housing has an installation cavity formed inside it, and the housing is provided with an air inlet and an air outlet communicating with the installation cavity.

[0007] A fan is disposed within the mounting cavity, and the fan is used to draw air from outside the housing into the mounting cavity through the air inlet;

[0008] A filter screen, which is detachably disposed at the air inlet, is used to filter the air drawn into the air inlet;

[0009] A heat exchanger is disposed in the mounting cavity and is used to exchange heat with the air in the mounting cavity. The fan is also used to blow the heat-exchanged air out of the mounting cavity through the air outlet.

[0010] A power supply module is disposed within the mounting cavity, and a power supply conductor is disposed on the power supply module;

[0011] A sterilization module is disposed within the mounting cavity, and a sterilization conductor is disposed on the sterilization module;

[0012] A conductive component is disposed on the filter screen, and the conductive component conducts the power supply conductor and the sterilization conductor.

[0013] With this configuration, both the power supply module and the sterilization module are located within the mounting cavity of the housing, and the conductive component is located on the filter screen. Since the conductive component can conduct power to the power supply conductor on the power supply module and sterilization conductor on the sterilization module, when the filter screen is located at the air inlet, the conductive component can conduct power to both the power supply conductor and the sterilization conductor. In this way, the power supply module can supply power to the sterilization module, thereby enabling the sterilization module to work and perform sterilization.

[0014] During the cleaning and maintenance of the indoor unit of an air conditioner, when the filter is removed from the air inlet, the filter can move the conductive component. As the conductive component moves, it disconnects the power supply conductor and the sterilization conductor, thereby de-energizing the sterilization module and stopping its operation. In this case, if the sterilization module is an ultraviolet sterilization module, the stopped sterilization module will not release ultraviolet rays, thus preventing users or maintenance personnel from being exposed to ultraviolet radiation during the cleaning and maintenance of the indoor unit, protecting their health.

[0015] Optionally, the conductive component is configured to conduct the power supply conductor and the sterilization conductor when the filter is disposed at the air inlet, and the conductive component is further configured to disconnect the power supply conductor and the sterilization conductor when the filter is removed from the air inlet.

[0016] With this configuration, when the filter is placed at the air inlet, it can further ensure that the power supply conductor and the sterilization conductor are connected by the conductive component, thereby further ensuring that the sterilization module can perform sterilization work.

[0017] During the cleaning and maintenance of the indoor unit of the air conditioner, when the filter is removed from the air inlet, the sterilization module will be powered off, which will further prevent users or maintenance personnel from being exposed to ultraviolet radiation when cleaning and maintaining the indoor unit of the air conditioner, and further protect the health and safety of users or maintenance personnel.

[0018] Optionally, the power supply conductor includes a positive terminal and a negative terminal;

[0019] The sterilization conductor includes a first sterilization conductor and a second sterilization conductor, the second sterilization conductor being spaced apart from the first sterilization conductor, the first sterilization conductor being electrically connected to the positive terminal, and the second sterilization conductor being electrically connected to the negative terminal;

[0020] The conductive component is inserted between the first sterilization conductor and the second sterilization conductor, and is in electrical contact with the first sterilization conductor and the second sterilization conductor, respectively.

[0021] With this configuration, since the conductive component is inserted between the first and second sterilization conductors, it not only facilitates the switching of the power supply conductor and the sterilization conductor, but also allows maintenance personnel to easily inspect and replace the sterilization module when it malfunctions.

[0022] Optionally, the sterilization conductor further includes a third sterilization conductor, which is spaced between the first sterilization conductor and the second sterilization conductor;

[0023] The conduction component includes:

[0024] A first plug is inserted between the first sterilization conductor and the third sterilization conductor, and is in electrical contact with the first sterilization conductor and the third sterilization conductor;

[0025] The second plug is provided independently of the first plug. The second plug is inserted between the second sterilization conductor and the third sterilization conductor and is in electrical contact with the second sterilization conductor and the third sterilization conductor.

[0026] With this design, since the first and second plugs are independently configured, when the filter is removed from the air inlet, as long as one plug disengages from the sterilization conductor during operation, the power supply circuit of the entire sterilization module will be cut off, causing the sterilization module to stop working. This is equivalent to setting up double protection. Compared to a single-plug design, it more reliably prevents the sterilization module from remaining operational during cleaning and maintenance. Therefore, when the sterilization module is an ultraviolet sterilization module, it can minimize the risk of users or maintenance personnel being exposed to ultraviolet radiation, further protecting personnel safety.

[0027] Optionally, a first channel is formed between the first sterilizing conductor and the third sterilizing conductor, with a first port and a second port at the two ends of the first channel extending in the direction of extension, the first port being for the first plug to be inserted into the first channel; the first sterilizing conductor and the third sterilizing conductor are spaced apart along a first direction, the first channel having a first dimension in the first direction, and the first dimension of the first port being larger than the first dimension of the second port; and / or,

[0028] A second channel is formed between the second sterilizing conductor and the third sterilizing conductor. The two ends of the second channel in the extension direction are a third port and a fourth port, respectively. The third port is for the second plug to be inserted into the second channel. The second sterilizing conductor and the third sterilizing conductor are spaced apart along a second direction. The second channel has a second dimension in the second direction. The second dimension of the third port is larger than the second dimension of the fourth port.

[0029] This design, with the first and third ports being larger than the second and fourth ports respectively, guides the insertion of the first and second plugs. The larger ports provide more space when the plug is near the channel, making it easier to align the plug and reducing insertion difficulty. Especially during filter installation, users or maintenance personnel can easily insert the plug without precise alignment, improving installation efficiency.

[0030] Optionally, the first plug includes a first insertion section, the first insertion section being diamond-shaped; and / or,

[0031] The second plug includes a second insertion section, which is diamond-shaped.

[0032] This design allows the diamond shape to act as a guide during insertion. Specifically, when the first or second plug approaches the corresponding first or second channel, the tip of the diamond-shaped insertion section enters the port first, automatically adjusting the plug's position and making it easier to align with the channel, thus reducing the difficulty of insertion. Even if there is a certain angular deviation or positional offset during installation, the special shape of the diamond helps the plug slide smoothly into the channel, improving installation efficiency and convenience.

[0033] Optionally, a third channel is further formed between the first sterilizing conductor and the third sterilizing conductor, the third channel for insertion of the first insertion segment, the two ends of the third channel in the extending direction being a fifth port and a sixth port, the fifth port being connected to the second port; the third channel has a third dimension in the first direction, the third dimension of the fifth port being smaller than the third dimension of the sixth port; and / or,

[0034] A fourth channel is also formed between the second sterilizing conductor and the third sterilizing conductor. The fourth channel is for the insertion of the second insertion segment. The two ends of the fourth channel in the extension direction are a seventh port and an eighth port, respectively. The seventh port is connected to the fourth port. The fourth channel has a fourth dimension in the second direction. The fourth dimension of the seventh port is smaller than the fourth dimension of the eighth port.

[0035] This design, with its third and fourth channels, increases the difficulty and complexity of inserting and removing the plug, which to some extent prevents accidental operation or contact with the plug by non-professionals. For example, if a user accidentally touches the filter, the plug is less likely to loosen or fall off due to slight external force because it needs to pass through specific channels and undergo dimensional changes to be inserted or removed. This reduces the risk of the sterilization module activating unexpectedly during normal use, and also reduces the risk of ultraviolet leakage when the sterilization module is an ultraviolet sterilization module.

[0036] Optionally, the sterilization module includes:

[0037] The module housing has a receiving cavity formed inside, and a light-emitting hole is provided on the module housing, which communicates with the receiving cavity. The sterilization conductor is disposed on the module housing.

[0038] A light source assembly, disposed within the receiving cavity, comprises:

[0039] A light source, wherein at least two light sources are provided, and the light sources are used to emit bactericidal light;

[0040] A reflective lampshade, wherein the reflective lampshade is disposed within the receiving cavity, and the reflective lampshade is provided with a reflective surface, the reflective surface comprising:

[0041] The system includes at least two arc-shaped concave sections, which are sequentially connected along a third direction. Any two connected arc-shaped concave sections are arranged in a W-shape. Each arc-shaped concave section corresponds to at least two light sources. The arc-shaped concave sections are used to reflect the sterilizing light emitted by the corresponding light source, so that the sterilizing light is emitted out of the receiving cavity through the light outlet.

[0042] This setup allows for the firstly, the germicidal light, such as ultraviolet light, to destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, rendering them unable to reproduce and survive. Therefore, it can quickly and effectively kill various harmful microorganisms in the air and on object surfaces, achieving a good sterilization and disinfection effect. This, in turn, helps improve indoor air quality and better protects the health of users.

[0043] Secondly, multiple arc-shaped concave segments are arranged in a W-shape and connected sequentially along a third direction on the reflector lamp cover, with each arc-shaped concave segment corresponding to a light source. In this way, each arc-shaped concave segment can reflect the sterilization light emitted by the corresponding light source in a specific direction, which can make the sterilization light more concentrated. This can reduce the dispersion of the sterilization light, thereby reducing the attenuation of light power, improving the utilization rate of the sterilization light, and enhancing the sterilization effect.

[0044] Furthermore, by forming a receiving cavity within the module housing and placing the light source component within the receiving cavity, the module housing can provide physical protection for the light source component, preventing it from being affected by external factors such as impacts, dust, and moisture. This not only helps extend the lifespan of the light source component but also helps ensure its stable emission of sterilization light.

[0045] Finally, placing the sterilization conductor on the module housing facilitates its installation on the sterilization module.

[0046] Optionally, the indoor unit of the air conditioner further includes:

[0047] An evaporator is disposed within the mounting cavity and spaced apart from the filter screen, and a sterilization module is disposed within the space between the evaporator and the filter screen;

[0048] The reflective surface is used to reflect the sterilizing light in a direction parallel to the filter, and / or the reflective surface is used to reflect the sterilizing light in the direction of the evaporator.

[0049] This design not only ensures that the germicidal light purifies and sterilizes the air flowing through the filter and the evaporator surface, but also prevents the germicidal light from escaping through the filter. This avoids accelerated aging of the filter and other structural components in the air inlet area, and also reduces the negative impact of the germicidal light on the user's visual experience.

[0050] Optionally, the reflective surface further includes:

[0051] A first planar segment is disposed toward the evaporator;

[0052] The second planar segment is disposed opposite to the first planar segment along the third direction, and in the third direction, the second planar segment and the first planar segment are respectively connected to the two sides of at least two arc-shaped concave segments;

[0053] The first planar segment has a first end disposed away from at least two of the arcuate concave segments, and the second planar segment has a second end disposed away from at least two of the arcuate concave segments. The projection of the second end onto the first planar segment along the third direction is an end projection, and the end projection is located on the side of the first end that is adjacent to at least two of the arcuate concave segments.

[0054] This configuration, on the one hand, allows the bactericidal light to be more concentrated through the combined action of the first and second planar segments and the arc-shaped concave segment, thereby further reducing the dispersion of the bactericidal light, further reducing the attenuation of light power, further improving the utilization rate of the bactericidal light, and further enhancing the bactericidal effect.

[0055] On the other hand, since the first planar segment is positioned towards the evaporator, and since the end projection of the second end on the first planar segment is located on the side of the first end that passes through at least two arc-shaped concave segments, the sterilization light can be reflected towards the evaporator as much as possible through the reflective lamp cover. This can further reduce the scattering of the sterilization light, thereby further reducing the attenuation of light power, further improving the utilization rate of the sterilization light, and further enhancing the sterilization effect.

[0078] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0080] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0082] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0083] As described in the background section of this application, with the improvement of people's living standards, the requirements for indoor air quality are also increasing. Air conditioners, as important devices for regulating indoor temperature and humidity, are prone to the growth of bacteria, mold, and other microorganisms inside, affecting indoor air quality and human health. To address this problem, related technologies have emerged that incorporate ultraviolet (UV) sterilization modules in the indoor unit of air conditioners. These UV sterilization modules effectively kill bacteria, viruses, and other microorganisms in the circulating air inside the air conditioner by emitting ultraviolet light, thereby improving indoor air quality.

[0084] However, the ultraviolet (UV) sterilization module in the indoor unit of an air conditioner poses certain safety hazards. Specifically, when users or repair personnel remove the filter for cleaning and maintenance, if the UV sterilization module is still operational, they may be directly exposed to high-intensity UV radiation. UV radiation is highly harmful to human skin and eyes; prolonged or high-intensity UV exposure can lead to skin burns, eye damage, and even increase the risk of skin cancer.

[0085] In view of the above-mentioned problems, this application provides an air conditioner indoor unit to solve the problem in the related technology that the ultraviolet sterilization module is still in working condition when the user or maintenance personnel are cleaning and maintaining it.

[0086] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0087] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the indoor unit of the air conditioner includes a casing 1, within which an installation cavity 11 is formed. The casing 1 is provided with an air inlet 12 and an air outlet 13 communicating with the installation cavity 11. This arrangement allows indoor air to enter the installation cavity 11 through the air inlet 12, while the air outlet 13 allows air processed by the indoor unit to return to the room, thus forming an effective air circulation system that continuously regulates indoor air temperature, humidity, and other parameters to maintain a comfortable indoor environment.

[0088] In some embodiments, the indoor unit of the air conditioner also includes a fan disposed within the mounting cavity 11. The fan is used to draw air from outside the casing 1 into the mounting cavity 11 through the air inlet 12. This configuration allows the air to enter the mounting cavity 11 at a faster speed and with a more stable flow rate, which is beneficial for providing a stable and continuous supply of air to be processed into the mounting cavity 11, thereby accelerating the rhythm of the entire indoor air circulation.

[0089] In some embodiments, such as Figure 1 and Figure 3 As shown, the indoor unit of the air conditioner also includes a filter 2, which is detachably installed at the air inlet 12. The filter 2 is used to filter the air drawn into the air inlet 12. This arrangement effectively prevents unfiltered air from entering the mounting cavity 11, thereby effectively preventing oil fumes from entering the indoor unit and ensuring its performance. Furthermore, detachably installing the filter 2 at the air inlet 12 facilitates its replacement, cleaning, and maintenance.

[0090] In some embodiments, the indoor unit of the air conditioner also includes a heat exchanger disposed in the mounting cavity 11. The heat exchanger is used to exchange heat with the air in the mounting cavity 11, and the fan is also used to blow the heat-exchanged air out of the mounting cavity 11 through the air outlet 13.

[0091] This design allows the heat exchanger to directly exchange heat with the air, rapidly changing the air temperature. This enables the indoor unit to quickly adjust the indoor air temperature upon receiving the user's set temperature adjustment command. Consequently, it can raise the indoor temperature in a short time, reducing the waiting time for the room to warm up. Furthermore, this efficient heat exchange process helps meet temperature control needs while avoiding excessive energy consumption. Additionally, the fan can more quickly regulate environmental parameters such as temperature and humidity throughout the room, reducing significant temperature or humidity differences between different areas.

[0092] In some embodiments, the indoor unit of the air conditioner also includes a power supply module, which is disposed within the mounting cavity 11 and has a power supply conductor. This arrangement, placing the power supply module within the mounting cavity 11, provides better protection, making it less susceptible to external impacts, dust, moisture, etc., reducing the possibility of short circuits, leakage, and other safety hazards caused by external factors, and ensuring user safety. Furthermore, the power supply conductor facilitates the electrical connection between the power supply module and the electrical components.

[0093] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the indoor unit of the air conditioner also includes a sterilization module 3, which is disposed in the mounting cavity 11, and a sterilization conductor 4 is disposed on the sterilization module 3.

[0094] With this setup, the sterilization function of the sterilization module 3 can effectively kill various harmful microorganisms in the air and on object surfaces, thereby improving indoor air quality and protecting users' health.

[0095] In some embodiments, such as Figure 3 As shown, the indoor unit of the air conditioner also includes a conductive component 5, which is disposed on the filter 2 and conducts power supply conductor and sterilization conductor 4.

[0096] With this configuration, during the cleaning and maintenance of the indoor air conditioner unit, when filter 2 is removed from the air inlet 12, filter 2 can move the conductive component 5. As the conductive component 5 moves, it disconnects the power supply conductor and the sterilization conductor 4, thereby de-energizing the sterilization module 3 and stopping its operation. In this case, when the sterilization module 3 is an ultraviolet sterilization module, the stopped sterilization module 3 will not release ultraviolet rays, thus preventing users or maintenance personnel from being exposed to ultraviolet radiation during the cleaning and maintenance of the indoor air conditioner unit, protecting the health and safety of users or maintenance personnel.

[0097] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the indoor unit of the air conditioner includes a casing 1, a fan, a filter 2, a heat exchanger, and a power supply module. The casing 1 has an installation cavity 11, and the casing 1 is provided with an air inlet 12 and an air outlet 13 communicating with the installation cavity 11.

[0098] A fan is installed inside the mounting cavity 11. The fan is used to draw air from outside the housing 1 into the mounting cavity 11 through the air inlet 12. A filter 2 is detachably installed at the air inlet 12. The filter 2 is used to filter the air drawn into the air inlet 12. A heat exchanger is installed inside the mounting cavity 11. The heat exchanger is used to exchange heat with the air inside the mounting cavity 11. The fan is also used to blow the heat-exchanged air out of the mounting cavity 11 through the air outlet 13.

[0099] like Figure 3 , Figure 4 and Figure 5 As shown, the indoor unit of the air conditioner also includes a sterilization module 3 and a conductive component 5. The power supply module is set in the mounting cavity 11 and a power supply conductor is provided on the power supply module. The sterilization module 3 is set in the mounting cavity 11 and a sterilization conductor 4 is provided on the sterilization module 3. The conductive component 5 is set on the filter screen 2 and conducts the power supply conductor and the sterilization conductor 4.

[0100] With this configuration, since both the power supply module and the sterilization module 3 are located within the mounting cavity 11 of the housing 1, and the conductive component 5 is located on the filter 2, and since the conductive component 5 can conduct power to the power supply conductor on the power supply module and the sterilization conductor 4 on the sterilization module 3, when the filter 2 is located at the air inlet 12, the conductive component 5 can conduct power to the power supply conductor and the sterilization conductor 4, thereby enabling the power supply module to supply power to the sterilization module 3, and thus the sterilization module 3 to work and perform sterilization.

[0101] During the cleaning and maintenance of the indoor air conditioner unit, when filter 2 is removed from the air inlet 12, filter 2 can move the conductive component 5. As the conductive component 5 moves, it disconnects the power supply conductor and the sterilization conductor 4, thereby de-energizing the sterilization module 3 and stopping its operation. In this case, when the sterilization module 3 is an ultraviolet sterilization module, the stopped sterilization module 3 will not release ultraviolet rays, thus preventing users or maintenance personnel from being exposed to ultraviolet radiation during the cleaning and maintenance of the indoor air conditioner unit, protecting the health and safety of users or maintenance personnel.

[0102] In this embodiment, the sterilization module 3 can be an ultraviolet sterilization module, or it can be an ion purification module, an active oxygen sterilization module, a photocatalytic module, or a formaldehyde purification module, etc. The type of sterilization module 3 is flexible and can be selected according to actual needs. This embodiment does not make specific limitations on this.

[0103] In this embodiment, in addition to supplying power to the sterilization module 3, the power supply module can also supply power to other electrical components of the air conditioner indoor unit. The power supply module has a flexible power supply setting, and this embodiment does not make specific limitations on this.

[0104] In some embodiments, the power supply module may further include a circuit board, with power supply conductors electrically connected to the circuit board. The circuit board is the core part of the power supply module, integrating various electronic components such as resistors, capacitors, inductors, and chips. The circuit board is used to convert, regulate, and control the input power supply to meet the different voltage and current requirements of various components of the air conditioner indoor unit.

[0105] This configuration, through the integration of various electronic components, allows the circuit board to precisely convert, regulate, and control the input power. It can convert mains power and other input power into different voltage and current values, accurately matching the different needs of each component in the indoor unit of the air conditioner. This ensures that each component operates stably under suitable power conditions, contributing to improved performance and reliability of the entire air conditioning system.

[0106] In some embodiments, the conductive component 5 is configured to conduct the power supply conductor and the sterilization conductor 4 when the filter 2 is disposed at the air inlet 12, and the conductive component 5 is further configured to disconnect the power supply conductor and the sterilization conductor 4 when the filter 2 is removed from the air inlet 12.

[0107] With this configuration, when the filter 2 is placed at the air inlet 12, it can further ensure that the conductive component 5 conducts the power supply conductor and the sterilization conductor 4, thereby further ensuring that the sterilization module 3 performs sterilization work.

[0108] During the cleaning and maintenance of the indoor unit of the air conditioner, when the filter 2 is removed from the air inlet 12, the sterilization module 3 will be de-energized, which will further prevent users or maintenance personnel from being exposed to ultraviolet radiation when cleaning and maintaining the indoor unit of the air conditioner, and further protect the health and safety of users or maintenance personnel.

[0109] In some embodiments, the conduction component 5 includes a magnetic induction switch and a magnetic element, wherein the magnetic induction switch is electrically connected between the power supply conductor and the sterilization conductor 4, and the magnetic element is disposed on the filter 2.

[0110] When filter 2 is near air inlet 12 but not fully in place, the magnetic field of the magnet can activate the magnetic induction switch, thereby enabling the conduction component 5 to conduct the power supply conductor and the sterilization conductor 4. Alternatively, when filter 2 begins to detach from air inlet 12 but is not fully detached, the magnetic induction switch will deactivate due to the weakening of the magnetic field, thereby enabling the conduction component 5 to disconnect the power supply conductor and the sterilization conductor 4.

[0111] This design serves two purposes. First, when filter 2 is not fully installed, the magnetic induction switch can promptly connect the power supply conductor and the sterilization conductor 4, enabling the sterilization module 3 to start working. This prevents situations where the user may mistakenly believe that filter 2 is properly installed but is actually not fully in place, thus preventing the sterilization function from being turned on. This avoids harmful substances such as bacteria and viruses from entering the device without effective treatment, ensuring safety during subsequent use.

[0112] On the other hand, the magnetic induction switch will disconnect when the filter 2 is not completely removed from the air inlet 12 due to the weakening of the magnetic field. This design prevents the user from being accidentally exposed to ultraviolet radiation during the removal of the filter 2, providing a safer environment for the user.

[0113] In some embodiments, the power supply conductor includes a positive terminal and a negative terminal. For example... Figure 6 and Figure 7 As shown, the sterilization conductor 4 includes a first sterilization conductor 41 and a second sterilization conductor 42. The second sterilization conductor 42 is spaced apart from the first sterilization conductor 41. The first sterilization conductor 41 is electrically connected to the positive terminal, and the second sterilization conductor 42 is electrically connected to the negative terminal.

[0114] like Figure 6 As shown, the conductive component 5 is inserted between the first sterilization conductor 41 and the second sterilization conductor 42, and is in electrical contact with the first sterilization conductor 41 and the second sterilization conductor 42 respectively.

[0115] With this configuration, since the conductive component 5 is inserted between the first sterilization conductor 41 and the second sterilization conductor 42, it not only facilitates the conduction and disconnection of the power supply conductor and the sterilization conductor 4 by the conductive component 5, but also allows maintenance personnel to easily inspect and replace the sterilization module 3 when it malfunctions.

[0116] In other embodiments, two independent conductive tracks are provided on the moving path of the filter 2, and the two conductive tracks are electrically connected to the power supply conductor and the sterilization conductor 4, respectively. The conductive component 5 is a conductive slider. When the filter 2 is placed at the air inlet 12, the conductive slider is in electrical contact with the two conductive tracks, thereby connecting the power supply conductor and the sterilization conductor 4. When the filter 2 is removed from the air inlet 12, the conductive slider disengages from the two conductive tracks, thereby disconnecting the power supply conductor and the sterilization conductor 4.

[0117] This design ensures a smooth sliding process and reduces potential mechanical damage during insertion and removal. Simultaneously, the large contact area between the conductive track and the conductive slider guarantees stable current transmission.

[0118] In other embodiments, the conducting component 5 can also conduct the power supply conductor and the sterilization conductor 4 in any other way, and the embodiments of this application do not specifically limit this.

[0119] In some embodiments, such as Figure 6 and Figure 7 As shown, the sterilization conductor 4 also includes a third sterilization conductor 43, which is spaced between the first sterilization conductor 41 and the second sterilization conductor 42.

[0120] like Figure 6As shown, the conductive component 5 includes a first plug 51 and a second plug 52. The first plug 51 is inserted between the first sterilization conductor 41 and the third sterilization conductor 43 and is in electrical contact with the first sterilization conductor 41 and the third sterilization conductor 43. The second plug 52 is provided independently of the first plug 51 and is inserted between the second sterilization conductor 42 and the third sterilization conductor 43 and is in electrical contact with the second sterilization conductor 42 and the third sterilization conductor 43.

[0121] With this configuration, since the first plug 51 and the second plug 52 are independently installed, when the filter 2 is removed from the air inlet 12, as long as one plug disengages from the sterilization conductor during operation, the power supply circuit of the entire sterilization module 3 will be cut off, causing the sterilization module 3 to stop working. This is equivalent to setting up double protection. Compared with a single plug design, it can more reliably prevent the sterilization module 3 from remaining in operation during cleaning and maintenance. Therefore, when the sterilization module 3 is an ultraviolet sterilization module, it can minimize the risk of users or maintenance personnel being exposed to ultraviolet radiation, which is beneficial to further protecting personnel safety.

[0122] In some embodiments, such as Figure 7 As shown, a first channel 6 is formed between the first sterilization conductor 41 and the third sterilization conductor 43. The two ends of the first channel 6 in the extending direction are a first port 61 and a second port 62, respectively. The first port 61 is for the first plug 51 to be inserted into the first channel 6. The first sterilization conductor 41 and the third sterilization conductor 43 are along a first direction (e.g., Figure 7 The X-direction spacing is set such that the first channel 6 has a first size in the first direction, and the first size of the first port 61 is larger than the first size of the second port 62. And / or, as... Figure 7 As shown, a second channel 7 is formed between the second sterilization conductor 42 and the third sterilization conductor 43. The two ends of the second channel 7 in its extending direction are a third port 71 and a fourth port 72, respectively. The third port 71 allows the second plug 52 to be inserted into the second channel 7. The second sterilization conductor 42 and the third sterilization conductor 43 extend along a second direction (e.g., ...). Figure 7 The X-direction spacing is set, the second channel 7 has a second size in the second direction, and the second size of the third port 71 is greater than the second size of the fourth port 72.

[0123] This design, with the first port 61 and the third port 71 being larger than the second port 62 and the fourth port 72 respectively, serves as a guide when inserting the first plug 51 and the second plug 52. The larger ports provide more space when the plug is near the channel, making it easier to align the plug and reducing insertion difficulty. Especially during filter 2 installation, users or maintenance personnel can easily insert the plug into the channel without precise alignment, improving installation efficiency.

[0124] In some embodiments, such as Figure 6 As shown, the first plug 51 includes a first insertion section 511, which is rhomboid in shape; and / or, as Figure 6 As shown, the second plug 52 includes a second insertion section 521, which is rhomboid in shape.

[0125] This design allows the rhombus shape to act as a good guide during insertion. Specifically, when the first plug 51 or the second plug 52 approaches the corresponding first channel 6 or second channel 7, the tip of the rhombus insertion segment enters the port first, automatically adjusting the plug's position and making it easier to align with the channel, thus reducing the difficulty of insertion. Even if there is a certain angular deviation or positional offset during installation, the special shape of the rhombus can help the plug slide smoothly into the channel, improving the efficiency and convenience of installation.

[0126] In some embodiments, such as Figure 7 As shown, a third channel 8 is also formed between the first sterilization conductor 41 and the third sterilization conductor 43, such as... Figure 6 As shown, the third channel 8 is for the insertion of the first insertion segment 511. The two ends of the third channel 8 in its extension direction are a fifth port 81 and a sixth port 82, respectively. The fifth port 81 is connected to the second port 62. The third channel 8 has a third dimension in the first direction, and the third dimension of the fifth port 81 is smaller than the third dimension of the sixth port 82. And / or, as... Figure 7 As shown, a fourth channel 9 is also formed between the second sterilization conductor 42 and the third sterilization conductor 43, such as... Figure 6 As shown, the fourth channel 9 is for the second insertion segment 521 to be inserted. The two ends of the fourth channel 9 in the extension direction are the seventh port 91 and the eighth port 92, respectively. The seventh port 91 is connected to the fourth port 92. The fourth channel 9 has a fourth dimension in the second direction. The fourth dimension of the seventh port 91 is smaller than the fourth dimension of the eighth port 92.

[0127] This design, with its third channel 8 and fourth channel 9, increases the difficulty and complexity of inserting and removing the plug. This, to some extent, prevents accidental operation or contact with the plug by non-professionals. For example, if a user accidentally touches the filter 2, the plug is less likely to loosen or fall off due to slight external force because it needs to pass through specific channels and undergo dimensional changes to be inserted or removed. This reduces the risk of the sterilization module 3 activating unexpectedly during normal use, and also reduces the risk of ultraviolet leakage when the sterilization module is an ultraviolet sterilization module.

[0128] In some embodiments, such as Figure 6 and Figure 7As shown, the sterilization module 3 includes a module housing 31, and a receiving cavity 311 is formed inside the module housing 31. The first sterilization conductor 41, the second sterilization conductor 42, and the third sterilization conductor 43 are all disposed within the receiving cavity 311, as shown. Figure 4 and Figure 5 As shown, the module housing 31 is provided with two insertion holes 312, both of which are connected to the receiving cavity 311. The two insertion holes 312 are respectively used for the insertion of the first plug 51 and the second plug 52.

[0129] This design allows the module housing 31 to protect the internal sterilization conductor 4. Specifically, on the one hand, it prevents dust, moisture, and other impurities from adhering to the surface of the sterilization conductor 4, thereby preventing conductor corrosion, short circuits, and other problems caused by these impurities. This extends the service life of the sterilization conductor 4 and ensures the stable operation of the sterilization module 3. On the other hand, the module housing 31 can withstand external forces such as impacts and compressions, thus preventing the sterilization conductor 4 from deforming or being damaged by external impacts, ensuring the structural integrity and performance stability of the sterilization module 3. In addition, the two insertion holes 312 facilitate the insertion of the first plug 51 and the second plug 52 between the first sterilization conductor 41 and the third sterilization conductor 43, and between the second sterilization conductor 42 and the third sterilization conductor 43, respectively.

[0130] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, the sterilization module 3 includes a module housing 31, a light source assembly 32, and a reflector lamp cover 33. The module housing 31 has a receiving cavity 311, and a light emission hole 313 is provided on the module housing 31, which is connected to the receiving cavity 311. The sterilization conductor 4 is disposed on the module housing 31.

[0131] like Figure 8 As shown, the light source assembly 32 is disposed in the receiving cavity 311. The light source assembly 32 includes a light source 321, and at least two light sources 321 are provided. The light sources 321 are used to emit bactericidal light.

[0132] like Figure 8 As shown, the reflector 33 is disposed within the receiving cavity 311, as... Figure 9 As shown, the reflector cover 33 is provided with a reflective surface 331, which includes an arc-shaped concave section 3311. At least two arc-shaped concave sections 3311 are provided, and these at least two arc-shaped concave sections 3311 are arranged along a third direction (e.g., ...). Figure 9The arc-shaped concave segments 3311 are connected sequentially in the Y direction, and any two connected arc-shaped concave segments 3311 are arranged in a W shape. At least two arc-shaped concave segments 3311 are arranged in a one-to-one correspondence with at least two light sources 321. The arc-shaped concave segments 3311 are used to reflect the sterilization light emitted by the corresponding light source 321 so that the sterilization light is emitted out of the receiving cavity 311 through the light outlet 313.

[0133] This setup allows for the firstly, the germicidal light, such as ultraviolet light, to destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, rendering them unable to reproduce and survive. Therefore, it can quickly and effectively kill various harmful microorganisms in the air and on object surfaces, achieving a good sterilization and disinfection effect. This, in turn, helps improve indoor air quality and better protects the health of users.

[0134] Secondly, multiple arc-shaped concave segments 3311 are arranged in a W-shape and connected sequentially along a third direction on the reflector lamp cover 33, with each arc-shaped concave segment 3311 corresponding to a light source 321. In this way, each arc-shaped concave segment 3311 can reflect the bactericidal light emitted by the corresponding light source 321 in a specific direction, which can make the bactericidal light more concentrated, thereby reducing the dispersion of the bactericidal light, reducing the attenuation of light power, improving the utilization rate of the bactericidal light, and enhancing the bactericidal effect.

[0135] Furthermore, a receiving cavity 311 is formed inside the module housing 31, and the light source assembly 32 is placed in the receiving cavity 311. In this way, the module housing 31 can provide physical protection for the light source assembly 32, preventing it from being affected by external factors such as collisions, dust, and moisture. This not only helps to extend the service life of the light source assembly 32, but also helps to ensure that it emits germicidal light stably.

[0136] Finally, the sterilization conductor 4 is placed on the module housing 31, which facilitates the installation of the sterilization conductor 4 on the sterilization module 3.

[0137] In some embodiments, the germicidal light is ultraviolet light, and the reflector 33 is a polytetrafluoroethylene lampshade.

[0138] This design allows the reflector lampshade 33 to be made of polytetrafluoroethylene (PTFE). Since PTFE has a high ultraviolet reflectivity, the scattering and loss of ultraviolet rays can be reduced through the PTFE lampshade, thereby improving the utilization rate of ultraviolet rays and effectively reflecting ultraviolet rays to the area that needs sterilization, thus enhancing the purification and sterilization effect of ultraviolet rays.

[0139] In other embodiments, the reflector 33 can also be a lampshade made of other materials. The material selection of the reflector 33 is flexible. Specifically, it can be selected according to actual needs. This application embodiment does not make specific limitations in this regard.

[0140] In some embodiments, such as Figure 9 As shown, the reflective lamp cover 33 is a reflective strip, which includes an arc-shaped plate 332. At least two arc-shaped plates 332 are provided, and the at least two arc-shaped plates 332 are connected sequentially along the second direction. The arc-shaped plate 332 has a concave plate surface located on one side of its own thickness direction, and the concave plate surface is an arc-shaped concave section 3311.

[0141] This design, with its relatively small footprint and weight, not only facilitates the lightweight design of the sterilization module 3 but also reduces the space occupied by the reflector lampshade 33 within the receiving cavity 311, thus contributing to a more compact design. Furthermore, the relatively simple structure of the reflector strip facilitates the manufacturing of the reflector lampshade 33, thereby reducing manufacturing costs.

[0142] In this embodiment, the curved plate 332 can be provided in two, three, or more configurations. Correspondingly, the light source 321 and the curved concave segment 3311 can also be provided in two, three, or more configurations, and the number of both the light source 321 and the curved concave segment 3311 is the same as the number of the curved plate 332. The number of the curved concave segment 3311, the light source 321, and the curved plate 332 can be flexibly set, and can be configured according to actual needs. This embodiment does not impose specific limitations on this.

[0143] In some embodiments, such as Figure 9 As shown, any two connected arc-shaped plates 332 together form a limiting recess 333, which is located on the side of the arc-shaped plate 332 away from the concave plate surface. The reflective strip has a first plate end 334 and a second plate end 335, which are respectively disposed on both sides of at least two arc-shaped plates 332.

[0144] like Figure 10 As shown, the inner wall of the receiving cavity 311 is provided with a limiting protrusion 314 and a limiting surface 315, as follows: Figure 8 and Figure 9 As shown, the reflector cover 33 is disposed between the limiting protrusion 314 and the limiting surface 315. The limiting protrusion 314 is in a limiting fit with the limiting recess 333, and the limiting surface 315 is in a limiting fit with the first plate end 334 and / or the second plate end 335.

[0145] This configuration, through the limiting engagement of the limiting protrusion 314 and the limiting recess 333, and the limiting engagement of the limiting surface 315 with the first plate end 334 and / or the second plate end 335, accurately confines the reflector lampshade 33 to a preset position within the receiving cavity 311. This ensures a more stable installation of the reflector lampshade 33 within the receiving cavity 311, effectively preventing displacement or shaking. This guarantees that each arc-shaped plate 332 precisely corresponds to a light source 321, thereby achieving accurate reflection and control of the sterilization light.

[0146] In some embodiments, such as Figure 3 As shown, the indoor unit of the air conditioner also includes an evaporator 10, which is disposed in the mounting cavity 11 and spaced apart from the filter screen 2. The sterilization module 3 is disposed in the space between the evaporator 10 and the filter screen 2.

[0147] The reflective surface 331 is used to reflect sterilization light in a direction parallel to the filter 2, and / or, the reflective surface 331 is used to reflect sterilization light in the direction of the evaporator 10.

[0148] This design not only ensures that the germicidal light purifies and sterilizes the air flowing through filter 2 and the surface of evaporator 10, but also prevents the germicidal light from escaping through filter 2. This not only avoids accelerated aging of filter 2 and other structural components in the air inlet 12 area, but also reduces the negative impact of the germicidal light on the user's visual experience.

[0149] In some embodiments, such as Figure 9 As shown, the reflective surface 331 also includes a first planar segment 3312 and a second planar segment 3313, wherein the first planar segment 3312 is disposed toward the evaporator 10, and the second planar segment 3313 is disposed along a third direction (e.g., ...). Figure 9 In the Y direction, the second plane segment 3313 and the first plane segment 3312 are respectively connected to the two sides of at least two arc-shaped concave segments 3311.

[0150] like Figure 9 As shown, the first planar segment 3312 has a first end 33121 disposed away from at least two arc-shaped concave segments 3311, and the second planar segment 3313 has a second end 33131 disposed away from at least two arc-shaped concave segments 3311. The projection of the second end 33131 onto the first planar segment 3312 along a third direction is the end projection, and the end projection is located on the side of the first end 33121 that is close to at least two arc-shaped concave segments 3311.

[0151] With this configuration, on the one hand, the combined action of the first planar segment 3312, the second planar segment 3313, and the arc-shaped concave segment 3311 can further concentrate the sterilization light, thereby further reducing the dispersion of the sterilization light, further reducing the attenuation of light power, further improving the utilization rate of the sterilization light, and further enhancing the sterilization effect.

[0152] On the other hand, since the first planar segment 3312 is positioned towards the evaporator 10, and since the end projection of the second end 33131 on the first planar segment 3312 is located on one side of the first end 33121 that passes through at least two arc-shaped concave segments 3311, the sterilization light can be reflected towards the evaporator 10 as much as possible through the reflector lamp cover 33. This can further reduce the scattering of the sterilization light, further reduce the attenuation of the light power, further improve the utilization rate of the sterilization light, and further enhance the sterilization effect.

[0153] In some embodiments, the inner wall of the light-emitting aperture 313 includes an inner wall section, which is disposed opposite to the first planar section 3312, such as... Figure 4 As shown, heat dissipation holes 316 are provided on the inner wall section of the hole.

[0154] This configuration, with heat dissipation through the heat dissipation hole 316, can prevent the heat from becoming too concentrated and unable to dissipate quickly due to the long-term operation of the light source 321. This can prevent the module housing 31 at the light emission hole 313 from aging too quickly and avoid the risk of local damage to the module housing 31. Furthermore, when the sterilization module 3 is an ultraviolet sterilization module, it can avoid the risk of ultraviolet leakage.

[0155] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
