[0002] Related art air conditioner indoor units address the problem of disinfection and sterilization by installing a sterilization device. This sterilization device sterilizes the air flowing into the air conditioner using a germicidal light source, such as an ultraviolet lamp. Because direct exposure to germicidal light sources is harmful to humans, the light from the germicidal light source needs to be directed toward the indoor heat exchanger. However, the air intake at the front panel itself is small and its penetration ability is weak. The light emitted by the sterilization device lacks guidance and has a limited irradiation range. Therefore, in theory, only a small portion of the air entering the side where the sterilization device is installed is sterilized, resulting in a longer sterilization time and low sterilization efficiency. If multiple UV lamps are installed, installation space is limited, and the cost of the sterilization device will also increase. Utility Model Content

[0040] The air conditioner sterilization device 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figures 1-10 As shown, the air conditioner sterilization device 1 according to an embodiment of the present invention includes a sterilization structure 100 and a sterilization light source 200 .

[0042] The sterilization structure 100 extends along the length of the air conditioner indoor unit 2 and has an air guide duct 101. A germicidal light source 200 is mounted on the sterilization structure 100 and is used to emit germicidal light. A light guide 102 extends along the length of the sterilization structure 100 and communicates with the air guide duct 101. The germicidal light source 200 aligns with and illuminates light into the light guide duct 102.

[0043] Among them, the inner wall of the light guide groove 102 is constructed with a reflective layer 11. The sterilization light of the sterilization light source 200 is irradiated to the reflective layer 11 and reflected by the reflective layer 11. The reflective layer 11 guides the sterilization light to be transmitted along the light guide groove 102. The sterilization light in the light guide groove 102 sterilizes the airflow of the air guide channel 101.

[0044] For example, the air conditioner sterilization device 1 is constructed as an elongated, plate-like structure along the length of the air conditioner indoor unit 2. One side of the device's width forms the air inlet, and the other side forms the air outlet. Air entering the air conditioner indoor unit 2 flows within the sterilization structure 100, where it is sterilized by light emitted from the sterilization light source 200. The sterilization light source 200 is a UV germicidal lamp, and the reflective layer 11 can be a highly reflective coating, such as a nano-reflective coating with a total reflectivity greater than 95%. This ensures that the sterilizing light is transmitted along a predetermined path, minimizing the likelihood of the sterilizing light reaching the exterior of the sterilization structure 100.

[0045] According to the air conditioner sterilization device 1 of the embodiment of the present invention, a sterilization structure 100 is used to construct a light guide groove 102, which defines a sterilization area for the sterilization light. The sterilization light emitted by the sterilization light source 200 irradiates and sterilizes the air passing through the light guide groove 102. The light guide groove 102 is a semi-enclosed structure, which is closed along the direction of light guidance and open along the direction of air flow to form an air guide channel 101. A reflective layer 11 is formed on the inner wall of the light guide groove 102. The sterilization light irradiated by the sterilization light source 200 is irradiated to the reflective layer 11 along a specific direction. The reflective layer 11 forms a total reflection on the sterilization light, guiding the sterilization light to move along a specific path. As a result, the sterilization light is only conducted inside the sterilization structure 100 and will not be scattered to the outside of the air conditioner indoor unit 2 due to diffuse reflection, thereby preventing harm to the human body. Furthermore, by transmitting the sterilizing light within the light guide groove 102, the light guide groove 102 greatly extends the path of the sterilizing light transmission compared to irradiating the sterilizing light toward the indoor heat exchanger 23. The sterilizing light, after multiple reflections, covers a larger area through which the airflow passes, thereby improving the sterilization efficiency of the air conditioner. Furthermore, by transmitting the sterilizing light along the light guide groove 102, the number of sterilizing light source components 200 can be reduced, making each sterilization by the sterilizing light source component 200 more efficient and shortening the duration of each sterilization. Since the time required for each irradiation by the sterilizing light source component 200 is shorter, the service life of the sterilizing light source component 200 can also be extended, and even to the point where the sterilizing light source component 200 does not need to be replaced during the service life of the air conditioner, further reducing costs.

[0046] Therefore, the air conditioner sterilization device 1 according to the embodiment of the present invention has the advantages of a large sterilization range, high sterilization efficiency, and reduced cost.

[0047] In some specific embodiments of the present invention, Figure 10 As shown, the reflective layer 11 includes a first reflective layer 111 and a second reflective layer 112 that are opposite to and parallel to each other, and the air guide channel 101 is located between the first reflective layer 111 and the second reflective layer 112 .

[0048] By arranging the first reflective layer 111 and the second reflective layer 112 in parallel, the sterilizing light irradiated onto the first reflective layer 111 and the sterilizing light irradiated onto the second reflective layer 112 can form the same reflection angle. When the sterilizing light emitted by the sterilizing light source 200 irradiates the first reflective layer 111 at a certain angle, for example, the sterilizing light source 200 irradiates the first reflective layer 111 at an incident angle of 30°, the first radiation layer then reflects the sterilizing light onto the second reflective layer 112. In this way, the sterilizing light irradiated by the sterilizing light source 200 is alternately reflected between the first reflective layer 111 and the second reflective layer 112, forming a sterilizing surface along the airflow path, and the air along the air guide channel 101 is sterilized.

[0049] Further, if Figure 9As shown, the air guide channel 101 extends along the width direction of the sterilization structure 100 and passes through the opposite side walls of the sterilization structure 100. The air guiding direction of the air guide channel 101 is perpendicular to the light guide groove 102. The air guide channel 101 is connected to the light guide groove 102 in the middle of the width direction of the sterilization structure 100.

[0050] For example, the air guide channels 101 are distributed throughout the length of the light guide slot 102, with the long sides of the air guide channels 101 being equal in length to the long sides of the light guide slot 102, resulting in a large air guide area and a large sterilization area. During the air guide process, the indoor air passes through the light guide slot 102 at the center of the sterilization structure 100. The airflow at all points in the light guide slot 102 is sterilized by the germicidal light source 200 within the light guide slot 102, ensuring that the airflow toward the indoor heat exchanger 23 is sterilized by the germicidal light to the greatest extent possible.

[0051] In some specific embodiments of the present invention, Figure 7 As shown, there are multiple light guide grooves 102 , which are arranged parallel and at intervals along the thickness direction of the sterilization structure 100 , and the opposite inner walls of each light guide groove 102 are formed with a first reflective layer 111 and a second reflective layer 112 .

[0052] Among them, the light guide groove 102 can be a part of the air guide channel 101. A sterilization light source component 200 can be set in each light guide groove 102; or a sterilization light source component 200 can be set at one end of the light guide structure, and the light emitted by the sterilization light source component 200 passes through multiple light guide grooves 102 at the same time. In this way, multiple light guide grooves 102 can be formed inside the sterilization structure 100, and each light guide groove 102 is connected to the air guide channel 101. The indoor air can pass through different air guide channels 101. The indoor air will pass through the light guide groove 102 during the process of being transmitted in different air guide channels 101. The sterilization light transmitted by different light guide grooves 102 can sterilize the airflow in each air guide channel 101. The sterilization structure 100 is divided into different sterilization areas. The sterilization light in each light guide groove 102 is relatively dense, the light intensity is high, and the sterilization is more sufficient.

[0053] In some specific embodiments of the present invention, Figure 4-Figure 6 As shown in FIG10 , the sterilization structure 100 includes a first reflective plate 110 , a second reflective plate 120 and a connecting seat 130 .

[0054] The germicidal light source 200 is mounted on a first reflector 110. A light guide groove 102 is formed on one side of the first reflector 110, with the bottom of the light guide groove 102 forming a first reflective layer 111. A second reflector 120 is arranged parallel to and spaced apart from the first reflector 110. A second reflective layer 112 is formed on the side of the second reflector 120 facing the first reflective layer 111. An air guide channel 101 is formed between the first reflector 110 and the second reflector 120. A connector 130 is adapted to be mounted on the air duct member 22. The connector 130 connects the first reflector 110 and the second reflector 120 at both ends of the germicidal structure 100.

[0055] By constructing a double-layer structure of the first reflector 110 and the second reflector 120, and connecting them at their ends, the first reflector 110 and the second reflector 120 are simplified in processing and have high structural strength. For example, the first reflector 110 and the second reflector 120 can be attached to the connecting base 130 at the ends using fasteners. The connecting base 130 forms a closed structure at the end, preventing the germicidal light from reaching outside the light guide trough 102.

[0056] Furthermore, the connection base 130, by being mounted on the air duct member 22, can keep the first reflector 110 and the second reflector 120 spaced apart from the indoor heat exchanger 23. This prevents the temperature of the indoor heat exchanger 23 from being directly transmitted to the sterilization structure 100, allowing the sterilization structure 100 to always maintain a suitable temperature. The sterilization structure 100 will not deform due to high or low temperatures, thereby extending its service life.

[0057] Furthermore, if Figure 5 and Figure 6 As shown, the connecting base 130 includes a transverse connecting base 131 and a longitudinal connecting base 132. The transverse connecting base 131 is adapted to be mounted on one end of the duct member 22, connects one end of the first reflector 110 and the second reflector 120, and extends in the longitudinal direction of the first reflector 110 and the second reflector 120. The longitudinal connecting base 132 is adapted to be mounted on the other end of the duct member 22, connects the other end of the first reflector 110 and the second reflector 120, and extends perpendicular to the first reflector 110 and the second reflector 120.

[0058] By constructing a transverse connecting seat 131 and a longitudinal connecting seat 132 to be installed with the air duct member 22 at both ends of the sterilization structure 100, positioning can be provided in both the transverse and longitudinal directions to prevent the sterilization structure 100 from being displaced. In some embodiments, the sterilization light source component 200 located at one end of the sterilization structure 100 is constructed with a power cord, and the power cord of the sterilization light source component 200 is led out from the end where the transverse connecting seat 131 is located. The power cords of the transverse connecting seat 131 and the sterilization light source component 200 are arranged side by side with each other and will not affect the wiring. In addition, the longitudinal connecting seat 132 is constructed into a closed structure, which closes the light guide groove 102 at the end away from the sterilization light source component 200, so that the sterilization light will not irradiate the light guide groove 102.

[0059] In some specific embodiments of the present invention, Figure 7 As shown, the first reflecting plate 110 is configured with an air guiding edge 111 on the air outlet side of the air guiding channel 101 , and the air guiding edge 111 extends toward the indoor heat exchanger 23 to guide the indoor air to the heat exchanger.

[0060] By constructing an inclined air guide edge 111 through the first reflective plate 110, the air guide path of the indoor air entering the air conditioner indoor unit 2 is limited, and the sterilized indoor air can be further conducted to the indoor heat exchanger 23. The indoor heat exchanger 23 then transports the clean gas into the room after heat exchange, ensuring that the air supply of the air conditioner indoor unit 2 is higher in cleanliness.

[0061] In some specific embodiments of the present invention, Figure 9 As shown, the germicidal light source 200 is installed at one end of the light guide groove 102 , and the germicidal light emitted by the germicidal light source 200 is reflected along the reflective layer 11 to the other end of the light guide groove 102 .

[0062] The light guide groove 102 is specifically a long groove, and the shape of the light guide groove 102 is adapted to the shape of the sterilization structure 100. Figure 9 Surfaces E and F are closed, and the germicidal light emitted by the germicidal light source 200 is continuously totally reflected by the reflective layers formed by surfaces A and B, and then transmitted along the length of the light guide slot 102. By transmitting the germicidal light from one end of the light guide slot 102 to the other, and by making surfaces C and D open, surfaces C and D are connected to form an air guide channel. Indoor air flows into the germicidal light source 200 through the indoor air inlet and flows along the air guide channel along the width of the light guide slot. The air conditioner sterilization device 1 only needs to install the germicidal structure 100 within the germicidal structure 100, thereby reducing the number of germicidal light sources 200 while ensuring the coverage area of ​​the germicidal light.

[0063] For example, the germicidal light source 200 can be an integrated structure installed together with the germicidal structure 100 and powered by a battery. Figure 5As shown, the germicidal light source component 200 may also be configured with a power harness 201 , which is led out from one end of the sterilization structure 100 and only needs to be able to supply power to the germicidal light source component 200 .

[0064] The air conditioner indoor unit 2 according to an embodiment of the present invention is described below.

[0065] like Figure 1-Figure 4 As shown, the indoor unit 2 of the air conditioner according to the embodiment of the present invention includes a housing 21, an air duct member 22, an indoor heat exchanger 23, and the air conditioner sterilization device 1 according to the above embodiment of the present invention.

[0066] Housing 21 is configured with an indoor air inlet 201 and an indoor air outlet. Duct 22 is installed within housing 21. Indoor heat exchanger 23 is mounted on duct 22, connecting indoor air inlet 201, indoor heat exchanger 23, and indoor air outlet. Air conditioning sterilization device 1 is mounted on duct 22, corresponding to the position of indoor air inlet 201.

[0067] The air conditioner sterilizing device is installed in the air duct member 22 and does not come into direct contact with the indoor heat exchanger 23 , so that the temperature of the indoor heat exchanger 23 does not directly exchange heat with the air conditioner sterilizing device 1 .

[0068] For example, the air conditioner sterilization device 1 is mounted on the air duct member 22 and extends along the length of the indoor air inlet 201. Furthermore, the light guide slot 102 extends along the length of the indoor air inlet 201. The air conditioner sterilization device 1 is located between the indoor heat exchanger 23 and the indoor air inlet 201, thereby sterilizing and disinfecting the airflow from the indoor air inlet 201 to the indoor heat exchanger 23, ensuring that the air directed to the indoor heat exchanger 23 remains clean.

[0069] Moreover, compared with the air conditioner indoor unit that irradiates sterilization light toward the indoor heat exchanger 23, the air conditioner sterilization device 1 according to the embodiment of the utility model greatly extends the path of sterilization light transmission. The sterilization light is reflected multiple times and covers a larger area where the air flow passes, thereby improving the air conditioner sterilization efficiency.

[0070] Furthermore, by transmitting the sterilizing light from the air conditioner sterilization device 1 along the light guide groove 102, the number of sterilizing light source components 200 can be reduced, making each sterilization operation more efficient and shortening the duration of each sterilization operation. Since each sterilizing light source component 200 requires less time for each irradiation, the service life of the sterilizing light source component 200 can also be extended, and it may even be possible to eliminate the need for replacement of the sterilizing light source component 200 during the air conditioner's service life, further reducing costs.

[0071] Therefore, the air conditioner according to the embodiment of the present invention has the advantages of a large sterilization range, high sterilization efficiency, and reduced cost by constructing the air conditioner sterilization device 1 according to the above embodiment of the present invention.

[0072] In some specific embodiments of the present invention, Figure 2 As shown, the indoor air inlet 201 extends along the length direction of the shell 21 , and both ends of the air conditioning sterilization device 1 are installed on the air duct member 22 and span the indoor air inlet 201 along the length direction of the shell 21 .

[0073] Specifically, the air conditioning sterilization device 1 is an integral structure extending from one end of the indoor air inlet 201 to the other. Compared to the air conditioning sterilization device 1 in the related art that only partially covers the indoor air inlet 201, the air conditioning sterilization device 1 of the present invention has a larger sterilization coverage area. The sterilization light emitted by the air conditioning sterilization device 1 is transmitted along the length of the side of the air conditioning sterilization device 1. Airflow at all points along the length of the indoor air inlet 201 can pass through the air conditioning sterilization device 1 for sterilization, shortening the sterilization irradiation time and improving the sterilization efficiency. In addition, due to the shortened sterilization time, the service life of the air conditioning sterilization device 1 is also increased. During the service life of the air conditioner, the air conditioning sterilization device 1 does not need to be replaced, and the maintenance cost is lower. At the same time, the air conditioning sterilization device 1 only requires a small number of sterilization light source components 200, reducing the cost of the sterilization light source components 200.

[0074] In some other embodiments, the air conditioner indoor unit 2 further includes a filter (not shown). The filter is mounted on the housing 21 and covers the air inlet. The air conditioner sterilization device 1 is located inside the filter, where the air intake is high. Because the light guide 102 spans the entire air conditioner air inlet, all air passing through the light guide 102 is exposed to the sterilizing light and sterilized. This significantly increases the volume of sterilized air at any one time, thereby improving sterilization efficiency.

[0075] Other structures and operations of the air conditioner sterilization device 1 and the air conditioner indoor unit 2 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.

[0076] In this application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0077] The compressor compresses high-temperature, high-pressure refrigerant gas and discharges the compressed gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0078] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0079] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0080] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0081] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0082] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
