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] In modern life, people are paying increasing attention to indoor air quality, and equipping air conditioner indoor units with ultraviolet sterilization modules has become a common way to improve air cleanliness. This module emits ultraviolet light to effectively kill bacteria, viruses, and other microorganisms in the air, creating a healthier breathing environment for users.

[0003] However, a serious safety hazard exists during the routine cleaning and maintenance of the air conditioner's indoor unit. When users remove the filter for cleaning, the ultraviolet (UV) sterilization module may still be operating. Since the UV sterilization module releases a large amount of high-intensity ultraviolet radiation when operating, users are easily exposed to harmful high-intensity UV radiation in this situation. 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 users are easily exposed to ultraviolet radiation damage when cleaning and maintaining the air conditioner indoor unit.

[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 fixedly disposed within the mounting cavity, and the power supply module includes power supply contacts;

[0011] A purification and sterilization module is disposed on the filter and located within the mounting cavity. The purification and sterilization module includes a power receiving contact that is in electrical contact with the power supply contact.

[0012] With this configuration, since the purification and sterilization module is located on the filter screen, and since the power receiving contacts of the purification and sterilization module are in electrical contact with the power supply contacts of the power supply module, when the filter screen is located at the air inlet, the power receiving contacts and the power supply contacts are in electrical contact, and the power supply module can supply power to the purification and sterilization module, thereby enabling the purification and sterilization module to work and perform purification and sterilization.

[0013] During the cleaning and maintenance of the indoor unit of the air conditioner, when the filter is removed from the air inlet, it moves the purification and sterilization module. As the module moves, the power contacts disconnect from the power supply contacts, thus de-energizing the purification and sterilization module and stopping its operation. In this situation, if the purification and sterilization module is an ultraviolet sterilization module, it will not release ultraviolet rays when it stops working, thereby preventing users from being exposed to harmful ultraviolet radiation during the cleaning and maintenance of the indoor unit.

[0014] Optionally, the purification and sterilization module includes:

[0015] The module housing is integrally connected to the filter screen, or the module housing is detachably disposed on the filter screen.

[0016] By integrating the module housing with the filter screen, loosening between the purification and sterilization module and the filter screen is prevented, ensuring the stability of the purification and sterilization module on the filter screen and enabling the filter screen to reliably move the purification and sterilization module. The integrated design also reduces the connection and assembly processes between components, thereby improving assembly efficiency.

[0017] The module housing is detachably mounted on the filter, allowing for easy removal and replacement when the purification and sterilization module malfunctions or reaches the end of its lifespan. This eliminates the need for complex disassembly of the entire indoor air conditioning unit, reducing maintenance costs and complexity while improving repair efficiency. Furthermore, the purification and sterilization module can be removed separately during regular filter cleaning, preventing damage during the process and extending its lifespan.

[0018] Optionally, the power supply module further includes:

[0019] The mounting component has a power supply contact located thereon. The purification and sterilization module is used to be installed on the mounting component when the filter is located at the air inlet. The purification and sterilization module is also used to detach from the mounting component when the filter is removed from the air inlet.

[0020] With this setup, the purification and sterilization module can be accurately installed on the mounting bracket when the filter is installed at the air inlet. Therefore, the mounting bracket provides a clear installation position for the purification and sterilization module, which in turn ensures that the power supply contacts and the power receiving contacts make correct electrical contact, ensuring the normal operation of the purification and sterilization module. It also facilitates assembly during the production process and helps to improve production efficiency.

[0021] Optionally, the mounting component includes:

[0022] The mounting frame encloses an installation space, the purification and sterilization module is installed in the installation space, and the power supply contacts are located on the inner side wall of the mounting frame.

[0023] The purification and sterilization module is used to enter the installation space along the first direction. The installation frame is provided with a limiting structure, which is used to prevent the purification and sterilization module from leaving the installation space along the first direction.

[0024] This design, firstly, provides a precise installation position for the purification and sterilization module within the installation space enclosed by the mounting frame. This not only ensures that the purification and sterilization module can be accurately installed in the predetermined position, but also facilitates the installation and detachment of the purification and sterilization module from the mounting components to a certain extent.

[0025] Secondly, the installation frame can simplify the structure of the installation components to a certain extent, which facilitates the processing and manufacturing of the installation components.

[0026] Finally, since the limiting structure can prevent the purification and sterilization module from leaving the installation space along the first direction, it can ensure that the purification and sterilization module remains in a stable position after installation and will not leave the installation space due to factors such as vibration during the operation of the indoor unit of the air conditioner. This can ensure stable electrical contact between the power receiving contact and the power supply contact, thereby reducing the probability of failure caused by poor contact.

[0027] Optionally, the purification and sterilization module includes:

[0028] The module housing has a receiving cavity formed inside it, and a light-emitting hole is provided on the module housing, which communicates with the receiving cavity. The power receiving contact is disposed on the module housing.

[0029] A light source assembly, disposed within the receiving cavity, comprises:

[0030] A light source, wherein at least two light sources are provided, and the light sources are used to emit purifying and sterilizing light;

[0031] 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:

[0032] The arc-shaped concave section is provided with at least two arc-shaped concave sections, which are connected sequentially along the second direction. Any two connected arc-shaped concave sections are arranged in a W shape. The at least two arc-shaped concave sections are provided in a one-to-one correspondence with at least two light sources. The arc-shaped concave sections are used to reflect the purification and sterilization light emitted by the corresponding light source, so that the purification and sterilization light is emitted out of the receiving cavity through the light outlet hole.

[0033] This setup, firstly, uses purifying and sterilizing 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, which in turn helps improve indoor air quality and better protects the health of users.

[0034] Secondly, multiple arc-shaped concave segments are arranged in a W-shape and connected sequentially along the second 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 purification and sterilization light emitted by the corresponding light source in a specific direction, which can make the purification and sterilization light more concentrated. This can reduce the dispersion of the purification and sterilization light, thereby reducing the attenuation of light power, improving the utilization rate of the purification and sterilization light, and enhancing the purification and sterilization effect.

[0035] 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 purifying and sterilizing light.

[0036] Finally, placing the power receiving contacts on the module housing facilitates the connection between the power receiving contacts and the power supply contacts.

[0037] Optionally, the reflective lampshade is a reflective strip, and the reflective strip includes:

[0038] An arc-shaped plate, wherein at least two arc-shaped plates are provided, and the at least two arc-shaped plates are connected sequentially along the second direction; the arc-shaped plate has a concave plate surface located on one side of its own thickness direction, and the concave plate surface is the arc-shaped concave segment.

[0039] This design, with its relatively small footprint and weight, not only facilitates a lightweight design for the purification and sterilization module but also reduces the space occupied by the reflector within the housing, thus enabling a more compact design. Furthermore, the relatively simple structure of the reflector facilitates the manufacturing of the reflector, reducing production costs.

[0040] Optionally, any two connected arc-shaped plates together form a limiting recess, the limiting recess being located on the side of the arc-shaped plate opposite to the concave plate surface; the reflective strip plate has a first plate end and a second plate end, the first plate end and the second plate end being respectively disposed on both sides of at least two of the arc-shaped plates;

[0041] The inner wall of the receiving cavity is provided with a limiting protrusion and a limiting surface. The reflective lamp cover is disposed between the limiting protrusion and the limiting surface. The limiting protrusion is limited and engaged with the limiting recess, and the limiting surface is limited and engaged with the end of the first plate and / or the end of the second plate.

[0042] This design, through the limiting engagement of the protruding and recessed parts, and the limiting engagement of the surface with the first and / or second plate ends, accurately positions the reflector lampshade within the receiving cavity. This ensures a more stable installation of the reflector lampshade within the cavity, effectively preventing displacement or shaking. This guarantees that each curved plate precisely corresponds to a light source, thereby achieving accurate reflection and control of the purifying and sterilizing light.

[0043] Optionally, the indoor unit of the air conditioner further includes:

[0044] An evaporator is disposed within the mounting cavity and spaced apart from the filter screen, and the purification and sterilization module is disposed in the space between the evaporator and the filter screen;

[0045] The reflective surface is used to reflect the purifying and sterilizing light in a direction parallel to the filter, and / or the reflective surface is used to reflect the purifying and sterilizing light in the direction of the evaporator.

[0046] This design not only ensures that the sterilizing light purifies and sterilizes the air flowing through the filter and the evaporator surface, but also prevents the 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 sterilizing light on the user's visual experience.

[0047] Optionally, the reflective surface further includes:

[0048] A first planar segment is disposed toward the evaporator;

[0049] The second planar segment is disposed opposite to the first planar segment along a second direction, and in the second direction, the second planar segment and the first planar segment are respectively connected to the two sides of at least two of the arc-shaped concave segments;

[0050] 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 second 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.

[0051] This configuration, on the one hand, through the combined action of the first and second planar segments and the arc-shaped concave segment, can further concentrate the purification and sterilization light, thereby further reducing the dispersion of the purification and sterilization light, further reducing the attenuation of light power, further improving the utilization rate of the purification and sterilization light, and further enhancing the purification and sterilization effect.

[0052] 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 purifying and sterilizing light can be reflected towards the evaporator as much as possible through the reflective lamp cover. This can further reduce the scattering of the purifying and sterilizing light, thereby further reducing the attenuation of light power, further improving the utilization rate of the purifying and sterilizing light, and further enhancing the purifying and sterilizing effect.

[0053] Optionally, the inner wall of the light-emitting hole includes an inner wall section, which is disposed opposite to the first planar section, and a heat dissipation hole is provided on the inner wall section.

[0054] This design, with heat dissipation holes, avoids excessive heat concentration due to prolonged operation of the light source, thus preventing the module casing at the light outlet from aging too quickly and avoiding the risk of localized damage to the module casing. Furthermore, when the purification and sterilization module is an ultraviolet sterilization module, it avoids the risk of ultraviolet leakage. Attached Figure Description

[0079] As described in the background section of this application, in modern life, people are paying increasing attention to indoor air quality, and equipping air conditioner indoor units with ultraviolet sterilization modules has become a common means of improving air cleanliness. This module effectively kills bacteria, viruses, and other microorganisms in the air by emitting ultraviolet light, creating a healthier breathing environment for users.

[0080] However, a serious safety hazard exists during the routine cleaning and maintenance of the air conditioner's indoor unit. When users remove the filter for cleaning, the ultraviolet (UV) sterilization module may still be operating. Since the UV sterilization module releases a large amount of high-intensity ultraviolet radiation when operating, users are easily exposed to harmful high-intensity UV radiation in this situation.

[0081] In view of the above-mentioned problems, this application provides an air conditioner indoor unit to solve the problem that users are easily exposed to ultraviolet radiation damage when cleaning and maintaining air conditioner indoor units in related technologies.

[0082] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0083] 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.

[0084] 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.

[0085] In some embodiments, such as Figure 1 and Figure 3As 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the indoor unit of the air conditioner further includes a power supply module, which is fixedly disposed within the mounting cavity 11, such as... Figure 4 As shown, the power supply module includes power supply contacts 3. This arrangement, placing the power supply module within the mounting cavity 11, provides better protection against external impacts, dust, moisture, and other contaminants, reducing the likelihood of short circuits, leakage, and other safety hazards caused by external factors, thus ensuring user safety. Furthermore, the power supply contacts 3 facilitate convenient electrical connection between the power supply module and the electrical components.

[0089] In some embodiments, such as Figure 3 As shown, the indoor unit of the air conditioner also includes a purification and sterilization module 4, which is disposed within the filter 2 and located in the mounting cavity 11, as shown. Figure 5 As shown, the purification and sterilization module 4 includes an electrical contact 41, which is in electrical contact with the power supply contact 3.

[0090] 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 will move the purification and sterilization module 4. As the purification and sterilization module 4 moves, the power receiving contact 41 will disconnect from the power supply contact 3, meaning the purification and sterilization module 4 will be de-energized and will stop working. In this case, when the purification and sterilization module 4 is an ultraviolet sterilization module, the stopped purification and sterilization module 4 will not release ultraviolet rays, thus preventing users from being harmed by ultraviolet radiation when cleaning and maintaining the indoor air conditioner unit.

[0091] 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, a power supply module, and a purification and sterilization module 4. 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.

[0092] 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.

[0093] The power supply module is fixedly installed inside the mounting cavity 11, such as... Figure 4 As shown, the power supply module includes power supply contacts 3, and the purification and sterilization module 4 is disposed on the filter 2 and located within the mounting cavity 11, as shown. Figure 5 As shown, the purification and sterilization module 4 includes an electrical contact 41, which is in electrical contact with the power supply contact 3.

[0094] With this configuration, since the purification and sterilization module 4 is located on the filter 2, and since the power receiving contact 41 of the purification and sterilization module 4 is in electrical contact with the power supply contact 3 of the power supply module, when the filter 2 is located at the air inlet 12, the power receiving contact 41 and the power supply contact 3 are in electrical contact, and the power supply module can supply power to the purification and sterilization module 4, thereby enabling the purification and sterilization module 4 to work and perform purification and sterilization.

[0095] During the cleaning and maintenance of the indoor unit of the air conditioner, when filter 2 is removed from the air inlet 12, filter 2 will move the purification and sterilization module 4. As the purification and sterilization module 4 moves, the power receiving contact 41 will disconnect from the power supply contact 3, meaning the purification and sterilization module 4 will be de-energized and will stop working. In this case, when the purification and sterilization module 4 is an ultraviolet sterilization module, the stopped purification and sterilization module 4 will not release ultraviolet rays, thus preventing users from being harmed by ultraviolet radiation when cleaning and maintaining the indoor unit of the air conditioner.

[0096] In this embodiment, in addition to supplying power to the purification and sterilization module 4, the power supply module can also supply power to other electrical components of the air conditioner indoor unit. The power supply target of the power supply module is set flexibly, and this embodiment does not make specific limitations on it.

[0097] In some embodiments, the power supply module may also include a circuit board, with the power supply contact 3 electrically connected to the circuit board. The circuit board is the core part of the power supply module and integrates various electronic components, such as resistors, capacitors, inductors, and chips. The circuit board is used to convert, regulate, and control the input power to meet the different voltage and current requirements of various components of the air conditioner indoor unit.

[0098] 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.

[0099] In some embodiments, such as Figure 6 As shown, the purification and sterilization module 4 includes a module housing 43, which is detachably mounted on the filter 2.

[0100] This design allows for easy removal and replacement of the purification and sterilization module 4 from the filter 2 when it malfunctions or reaches the end of its service life. This eliminates the need for complex disassembly of the entire indoor air conditioning unit, reducing maintenance costs and complexity while improving repair efficiency. Furthermore, when cleaning the filter 2, the purification and sterilization module 4 can be removed separately, preventing damage during cleaning and extending its lifespan.

[0101] In addition, users can freely install different purification and sterilization modules 4 according to different needs, such as ultraviolet sterilization module, ion purification module, active oxygen sterilization module, photocatalytic module and formaldehyde purification module, which can help meet the different purification and sterilization needs of users.

[0102] In some embodiments, such as Figure 6 As shown, a fixing hook 5 is provided on the filter screen 2, and the module housing 43 is detachably mounted on the filter screen 2 via the fixing hook 5. This arrangement, through the fixing hook 5, not only ensures the stability of the purification and sterilization module 4 mounted on the filter screen 2, but also facilitates the installation and removal of the purification and sterilization module 4 to a certain extent.

[0103] In other embodiments, the module housing 43 can also be detachably mounted on the filter screen 2 by means of bolt connection, magnetic attraction, etc. The detachable mounting of the module housing 43 is more flexible. Specifically, it can be mounted according to actual needs. This application embodiment does not make specific limitations in this regard.

[0104] In some embodiments, such as Figure 3 As shown, the purification and sterilization module 4 includes a module housing 43, which is integrally connected to the filter screen 2.

[0105] This design prevents the purification and sterilization module 4 from becoming loose from the filter screen 2, ensuring the stability of the purification and sterilization module 4 on the filter screen 2, and thus enabling the filter screen 2 to reliably move the purification and sterilization module 4. At the same time, the integrated design reduces the connection and assembly processes between components, thereby improving assembly efficiency.

[0106] In some embodiments, such as Figure 3 and Figure 4 As shown, the power supply module also includes a mounting component 6, and power supply contacts 3 are disposed on the mounting component 6, as shown. Figure 3 and Figure 7 As shown, the purification and sterilization module 4 is used to install on the mounting part 6 when the filter screen 2 is set at the air inlet 12, and the purification and sterilization module 4 is also used to detach from the mounting part 6 when the filter screen 2 is removed from the air inlet 12.

[0107] With this configuration, the purification and sterilization module 4 can be accurately installed on the mounting part 6 when the filter 2 is installed at the air inlet 12. Therefore, the mounting part 6 provides a clear installation position for the purification and sterilization module 4, which in turn ensures that the power supply contact 3 and the power receiving contact 41 make correct electrical contact, ensuring the normal operation of the purification and sterilization module 4. It also facilitates assembly during the production process and helps to improve production efficiency.

[0108] In some embodiments, such as Figure 4 As shown, the mounting component 6 includes a mounting frame 61, which encloses an installation space 62. The purification and sterilization module 4 is installed in the installation space 62, and the power supply contact 3 is located on the inner side wall of the mounting frame 61.

[0109] Purification and sterilization module 4 is used along the first direction (e.g.) Figure 4 (In the Y direction) enter the installation space 62, such as Figure 4 As shown, a limiting structure 63 is provided on the mounting frame 61. The limiting structure 63 is used to prevent the purification and sterilization module 4 from being disengaged from the mounting space 62 in the first direction.

[0110] With this setup, firstly, the installation space 62 enclosed by the mounting frame 61 provides a precise installation position for the purification and sterilization module 4. This not only ensures that the purification and sterilization module 4 can be accurately installed in the predetermined position, but also facilitates the installation and removal of the purification and sterilization module 4 from the mounting component 6 to a certain extent.

[0111] Secondly, by installing the frame 61, the structure of the mounting component 6 can be simplified to a certain extent, which is conducive to the processing and manufacturing of the mounting component 6.

[0112] Finally, since the limiting structure 63 can prevent the purification and sterilization module 4 from leaving the installation space 62 in the first direction, it can ensure that the purification and sterilization module 4 remains in a stable position after installation and will not leave the installation space 62 due to factors such as vibration during the operation of the indoor unit of the air conditioner. This can ensure stable electrical contact between the power receiving contact 41 and the power supply contact 3, thereby reducing the probability of failure caused by poor contact.

[0113] In this embodiment, the limiting structure 63 can be a strip-shaped protrusion extending along the inner sidewall of the mounting frame 61. Figure 4 As shown), it can also be a blocking plate on the first direction side of the blocking mounting frame 61. The structure of the limiting structure 63 is more flexible. Specifically, it can be set according to actual needs. This application embodiment does not make specific limitations on this.

[0114] In some embodiments, such as Figure 8 As shown, the purification and sterilization module 4 includes a light source assembly 42, a module housing 43, and a reflector lampshade 44. The module housing 43 has a receiving cavity 431 formed within it. Figure 7 and Figure 8 As shown, the module housing 43 is provided with a light emission hole 432, which communicates with the receiving cavity 431, as... Figure 5 As shown, the power receiving contact 41 is disposed on the module housing 43.

[0115] like Figure 8 As shown, the light source assembly 42 is disposed in the receiving cavity 431. The light source assembly 42 includes a light source 421, and at least two light sources 421 are provided. The light sources 421 are used to emit purifying and sterilizing light.

[0116] like Figure 8 As shown, the reflector 44 is disposed within the receiving cavity 431, as... Figure 9 As shown, the reflector cover 44 is provided with a reflective surface 441, which includes an arc-shaped concave section 4411. At least two arc-shaped concave sections 4411 are provided, and these at least two arc-shaped concave sections 4411 are arranged along a second direction (e.g., Figure 9The arc-shaped concave segments 4411 are connected sequentially in the Y direction, and any two connected arc-shaped concave segments 4411 are arranged in a W shape. At least two arc-shaped concave segments 4411 are arranged in a one-to-one correspondence with at least two light sources 421. The arc-shaped concave segments 4411 are used to reflect the purification and sterilization light emitted by the corresponding light source 421, so that the purification and sterilization light is emitted out of the receiving cavity 431 through the light outlet 432.

[0117] This setup, firstly, uses purifying and sterilizing 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, which in turn helps improve indoor air quality and better protects the health of users.

[0118] Secondly, multiple arc-shaped concave segments 4411 are arranged in a W-shape and connected sequentially along the second direction on the reflector lamp cover 44, with each arc-shaped concave segment 4411 corresponding to a light source 421. In this way, each arc-shaped concave segment 4411 can reflect the purification and sterilization light emitted by the corresponding light source 421 in a specific direction, which can make the purification and sterilization light more concentrated, thereby reducing the dispersion of the purification and sterilization light, thus reducing the attenuation of light power, improving the utilization rate of the purification and sterilization light, and enhancing the purification and sterilization effect.

[0119] Furthermore, a receiving cavity 431 is formed inside the module housing 43, and the light source assembly 42 is placed in the receiving cavity 431. In this way, the module housing 43 can provide physical protection for the light source assembly 42, 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 42, but also helps to ensure that it emits purification and sterilization light stably.

[0120] Finally, the power receiving contact 41 is located on the module housing 43, which facilitates the connection between the power receiving contact 41 and the power supply contact 3.

[0121] In some embodiments, such as Figure 4 As shown, the side of the mounting frame 61 is provided with a clearance opening 611, such as... Figure 7 As shown, the clearance opening 611 and the light emission hole 432 are correspondingly arranged. The clearance opening 611 is used to prevent the purification and sterilization light emitted through the light emission hole 432 from exiting the installation space 62. With this arrangement, the clearance opening 611 facilitates the exit of the purification and sterilization light emitted through the light emission hole 432 from the installation space 62.

[0122] In some embodiments, the purifying and sterilizing light is ultraviolet light, and the reflector 44 is a polytetrafluoroethylene lampshade.

[0123] This design allows the reflector lampshade 44 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.

[0124] In other embodiments, the reflector 44 can also be a lampshade made of other materials. The material selection of the reflector 44 is flexible. Specifically, it can be selected according to actual needs. This application embodiment does not make specific limitations in this regard.

[0125] In some embodiments, such as Figure 9 As shown, the reflective lampshade 44 is a reflective strip, which includes an arc-shaped plate 442. At least two arc-shaped plates 442 are provided, and the at least two arc-shaped plates 442 are connected sequentially along the second direction. The arc-shaped plate 442 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 4411.

[0126] This design, with its relatively small footprint and weight, not only facilitates the lightweight design of the purification and sterilization module 4 but also reduces the space occupied by the reflector lampshade 44 within the housing cavity 431, thus contributing to a more compact design. Furthermore, the relatively simple structure of the reflector strip facilitates the processing and manufacturing of the reflector lampshade 44, thereby reducing manufacturing costs.

[0127] In this embodiment, the curved plate 442 can be provided in two, three, or more configurations. Correspondingly, the light source 421 and the curved concave segment 4411 can also be provided in two, three, or more configurations, and the number of both the light source 421 and the curved concave segment 4411 is the same as the number of curved plates 442. The number of curved concave segments 4411, light sources 421, and curved plates 442 can be flexibly set, and can be configured according to actual needs. This embodiment does not impose specific limitations on this.

[0128] In some embodiments, such as Figure 9 As shown, any two connected arc-shaped plates 442 together form a limiting recess 443, which is located on the side of the arc-shaped plate 442 away from the concave plate surface. The reflective strip has a first plate end 444 and a second plate end 445, which are respectively disposed on both sides of at least two arc-shaped plates 442.

[0129] like Figure 10 As shown, the inner wall of the receiving cavity 431 is provided with a limiting protrusion 45 and a limiting surface 46, as follows: Figure 8 and Figure 9As shown, the reflector cover 44 is disposed between the limiting protrusion 45 and the limiting surface 46. The limiting protrusion 45 is in a limiting engagement with the limiting recess 443, and the limiting surface 46 is in a limiting engagement with the first plate end 444 and / or the second plate end 445.

[0130] This configuration, through the limiting engagement of the limiting protrusion 45 and the limiting recess 443, and the limiting engagement of the limiting surface 46 with the first plate end 444 and / or the second plate end 445, accurately confines the reflector lampshade 44 to a preset position within the receiving cavity 431. This ensures a more stable installation of the reflector lampshade 44 within the receiving cavity 431, effectively preventing displacement or shaking. This guarantees that each arc-shaped plate 442 precisely corresponds to a light source 421, thereby achieving accurate reflection and control of the purifying and sterilizing light.

[0131] In some embodiments, such as Figure 3 As shown, the indoor unit of the air conditioner also includes an evaporator 7, which is disposed in the mounting cavity 11 and spaced apart from the filter screen 2. The purification and sterilization module 4 is disposed in the space between the evaporator 7 and the filter screen 2.

[0132] The reflective surface 441 is used to reflect the purifying and sterilizing light in a direction parallel to the filter 2, and / or, the reflective surface 441 is used to reflect the purifying and sterilizing light in the direction of the evaporator 7.

[0133] This design not only ensures that the purifying and sterilizing light can purify and sterilize the air flowing through filter 2 and the surface of evaporator 7, but also prevents the purifying and sterilizing 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 adverse visual impact of the purifying and sterilizing light on the user's experience.

[0134] In some embodiments, such as Figure 9 As shown, the reflective surface 441 further includes a first planar segment 4412 and a second planar segment 4413, wherein the first planar segment 4412 is disposed toward the evaporator 7, and the second planar segment 4413 is disposed along a second direction (e.g., ...). Figure 9 In the Y direction, the two planar segments 4413 and 4412 are respectively connected to the two sides of at least two arc-shaped concave segments 4411 in the second direction.

[0135] like Figure 9 As shown, the first planar segment 4412 has a first end 44121 disposed away from at least two arcuate concave segments 4411, and the second planar segment 4413 has a second end 44131 disposed away from at least two arcuate concave segments 4411, the second end 44131 being along a second direction (e.g. Figure 9The projection of the first planar segment 4412 (in the Y direction) onto the first planar segment 4412 is the end projection, which is located on the side of the first end 44121 that is close to at least two arc-shaped concave segments 4411.

[0136] With this configuration, on the one hand, the combined action of the first planar segment 4412, the second planar segment 4413, and the arc-shaped concave segment 4411 can further concentrate the purification and sterilization light, thereby further reducing the dispersion of the purification and sterilization light, further reducing the attenuation of light power, further improving the utilization rate of the purification and sterilization light, and further enhancing the purification and sterilization effect.

[0137] On the other hand, since the first planar segment 4412 is positioned towards the evaporator 7, and since the end projection of the second end 44131 on the first planar segment 4412 is located on one side of the first end 44121 that passes through at least two arc-shaped concave segments 4411, the reflector lamp cover 44 can reflect the purifying and sterilizing light towards the evaporator 7 as much as possible. This can further reduce the scattering of the purifying and sterilizing light, thereby further reducing the attenuation of light power, further improving the utilization rate of the purifying and sterilizing light, and further enhancing the purifying and sterilizing effect.

[0138] In some embodiments, the inner wall of the light-emitting aperture 432 includes an inner wall section, which is disposed opposite to the first planar section 4412, such as... Figure 7 As shown, heat dissipation holes 47 are provided on the inner wall section of the hole.

[0139] This configuration, with heat dissipation through the heat dissipation hole 47, can prevent the heat from becoming too concentrated and unable to dissipate quickly due to the long-term operation of the light source 421. This can prevent the module housing 43 at the light emission hole 432 from aging too quickly and avoid the risk of local damage to the module housing 43. Furthermore, when the purification and sterilization module 4 is an ultraviolet sterilization module, it can avoid the risk of ultraviolet leakage.

[0140] 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.
