Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.

In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numbers and/or letters in different examples. This repetition is for purposes of simplicity and clarity and does not by itself indicate a relationship between the various embodiments and/or arrangements discussed. Furthermore, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the applicability of other processes and/or the use of other materials.

Next, with reference to the drawings, the air conditioner 100 according to the embodiment of the present application is described.

As shown in Figures 1, 6 and 7, the air conditioner 100 includes a casing 1, an indoor heat exchanger 2 and an indoor fan 3. An indoor air duct 1a is defined in the casing 1, and the casing 1 is formed with an indoor air duct. The indoor air inlet 1b and the indoor air outlet 1c are respectively connected to the duct 1a. The indoor heat exchanger 2 and the indoor fan 3 are both located in the indoor air duct 1a; then, driven by the indoor fan 3, the indoor air can pass through the indoor air inlet 1b. It flows to the indoor air duct 1a, exchanges heat with the indoor heat exchanger 2, and finally flows indoors through the indoor air outlet 1c to achieve indoor air circulation and at least adjust the indoor temperature.

The air conditioner 100 also includes a fresh air module 4. The fresh air module 4 is installed in the casing 1. The fresh air module 4 can be directly or indirectly connected to the casing 1. The fresh air module 4 includes a casing 41 and a fresh air fan 42. The fresh air is defined in the casing 41. Air duct 4a, fresh air The fan 42 is located in the fresh air duct 4a, and the housing 41 is formed with a fresh air inlet 4b and a fresh air outlet 4c that are respectively connected with the fresh air duct 4a; then, driven by the fresh air fan 42, the outdoor fresh air can flow to the fresh air through the fresh air inlet 4b. The air duct 4a finally flows to the room directly or indirectly through the fresh air outlet 4c to realize circulation and ventilation between indoor air and outdoor air, so as to improve indoor air quality.

The air conditioner 100 also includes a sterilization module 5. The sterilization module 5 is located in the casing 1. The sterilization module 5 can be directly or indirectly connected to the casing 1. The sterilization module 5 is used to at least sterilize the indoor air duct 1a and the fresh air duct 4a. The air flow (such as cold air or hot air in the indoor air duct 1a, cold air or hot air in the fresh air duct 4a) is sterilized to improve indoor air quality.

It can be seen that the air conditioner 100 has both a fresh air function and a sterilization function. At the same time, the sterilization module 3 can sterilize the air flowing into the room through the fresh air duct 4a to ensure the quality of the air flowing into the room and enrich the functions of the air conditioner 100. Function.

Among them, the sterilization module 5 includes a pulse light source 51. The pulse light source 51 is used to output pulse strong light to sterilize at least the air flow in the indoor air duct 1a and the fresh air duct 4a. Then the pulse strong light irradiates the indoor air duct 1a and the fresh air duct 4a. The airflow in 4a is used to achieve efficient sterilization of indoor air duct 1a and fresh air duct 4a. The pulsed strong light can remove gaseous pollutants (for example, formaldehyde, or toluene, or acetic acid, etc.) in indoor air duct 1a and fresh air duct 4a. ), making the indoor air and the air entering the room through the fresh air duct 4a cleaner, so as to effectively improve the indoor air quality, improve indoor comfort, meet the user's demand for clean air, and enhance the user's experience.

As a result, the pulsed light source 51 outputs pulsed strong light to cause great harm to bacteria and other microorganisms, reduce the activity of their internal enzymes and even destroy their DNA and RNA structures, eventually leading to the death of bacteria and other microorganisms; moreover, the pulsed light source 51 is pulsed in the form of Output strong white light to illuminate at least the air in the indoor air duct 1a and the fresh air duct 4a to kill bacteria, and during the sterilization process, there is no need to heat the air, which reduces the energy consumption of the sterilization module 5 and reduces the User cost of use.

Among them, the pulsed strong light includes multi-spectral light, including ultraviolet light, infrared light and visible light. Ultraviolet light plays an important role in sterilization, and infrared light also has a synergistic sterilization effect, so that the sterilization module 5 has a good sterilization effect and sterilization effect. efficiency, to ensure the sterilization ability of the sterilization module 5, and at the same time further reduce the energy consumption of the sterilization module 5; through the ultraviolet light in the pulsed strong light, it can destroy the genetic material of bacteria and other microorganisms, causing bacterial death, and through the infrared light in the pulsed strong light It can quickly heat up bacteria, causing them to dehydrate and die. Through the pulse flash effect, high penetration and high impact of visible light in pulsed strong light, it can destroy the bacterial protein structure, denature the protein, and cause bacterial death. It has good sterilization energy efficiency and Adaptability.

It can be seen that the pulsed strong light output by the sterilization module 5 can at least achieve safe (mercury-free), powerful, and energy-saving cold sterilization (i.e., non-heating sterilization) of the air flow in the indoor air duct 1a and the fresh air duct 4a. During sterilization, there is no need to heat the air flow, which is beneficial to saving sterilization energy consumption. At the same time, it has basically no impact on the temperature of the air flow, making it easy to ensure The air conditioner 100 regulates indoor temperature, etc., and if the air conditioner 100 is used for cooling, since the sterilization module 5 basically does not affect the air flow temperature, it is easy to ensure the cooling efficiency of the air conditioner 100 and at the same time save the cooling energy consumption of the air conditioner 100; At the same time, the sterilization module 3 causes less environmental pollution when working, is convenient for providing users with a friendly usage environment, and does not cause harm to the human body, which is conducive to ensuring the health of users.

According to the air conditioner 100 of the embodiment of the present application, the pulse strong light released by the pulse light source 51 can sterilize at least the indoor air duct 1a and the fresh air duct 4a multiple times in a very short time, thereby improving the sterilization of the indoor air duct 1a and the fresh air. The sterilization efficiency and sterilization effect of the air duct 4a, thereby achieving efficient sterilization of the indoor air duct 1a and the fresh air duct 4a, and improving indoor air quality; compared with ultraviolet sterilization, the sterilization module 5 of the present application can sterilize more types of microorganisms sterilization, saving sterilization time, and the sterilization module 5 consumes less energy.

Compared with some technologies, ultraviolet sterilization has actinic effect, which is the main sterilizing mechanism of ultraviolet sterilization. Actinic effect refers to the optical reaction produced when microorganisms are exposed to light of a specific wavelength; when microorganisms such as double helices in bacteria When genetic information is irradiated by ultraviolet light, it will form part of metadiazepine and isomers of metadiazepine. This substance will cause obstacles to the metabolic function of the microorganism itself and cause genetic problems of the microorganism. , until death.

Pulse strong light has a photothermal sterilization mechanism. The photothermal effect means that light energy is absorbed by substances and a temperature rise occurs. When microorganisms are irradiated by pulsed strong light at close range, due to the absorption of a large amount of light energy in a short period of time, the surface temperature of the microorganisms increases. will rise sharply, and the surface structure will be completely destroyed and die. Since the entire photothermal process is very short, the illuminated object will not produce a temperature rise. Therefore, pulsed intense light using the photothermal sterilization mechanism can effectively kill all microorganisms.

It can be seen that, as shown in the table below, the comparison between pulsed strong light sterilization and ultraviolet light sterilization, pulsed strong light also covers the ultraviolet band, so pulsed strong light also has an actinic sterilization mechanism; however, the actinic sterilization mechanism in pulsed strong light is only It plays a supporting role. For mold and spore microorganisms, ultraviolet rays are difficult to penetrate the dense cell wall structure and DNA substances cannot absorb ultraviolet rays. Therefore, the sterilization efficiency of ultraviolet sterilization is very low compared to pulsed strong light.

The pulse light source 51 ionizes the inert gas through a high-voltage power supply and excites photons to generate instantaneous high-intensity light. Usually the pulsed light includes multi-spectral light from 100 nm to 1 mm. For example, the pulse light source 51 includes a xenon lamp 511. The pulse strong light applies a higher voltage to the xenon lamp 511 through the power supply, causing a large amount of xenon gas in the xenon lamp to be ionized in a very short time, causing the xenon gas to emit high-intensity light. The radiation form will excite photons to produce an instantaneous release of high-intensity light. Of course, the pulse light source 51 is not limited to this.

In some embodiments, as shown in FIG. 8 , the pulse light source 51 includes a xenon lamp 511 , a lampshade 512 and a seal 513 . The xenon lamp 511 is filled with inert gases including xenon, and there is no pollution and no harm to the human body. The lampshade 512 is set It is provided on the outside of the xenon lamp 511, and openings are respectively formed at both axial ends of the lampshade 512, so that the xenon lamp 511 fits into the lampshade 512 through the openings. The sealing member 513 is sealed at the opening, and the sealing member 513 and the lampshade 512 jointly define the installation area. If the installation cavity accommodates the xenon lamp 511, the two seals 513 can seal the xenon lamp 511 in the installation cavity, which is beneficial to reducing the risk during the installation and removal of the pulse light source 51. Among them, the lampshade 512 is a transparent part, which improves the light transmittance of the strong pulse light released by the xenon lamp 511 and reduces the energy loss of the pulse light source 51 .

For example, the lampshade 512 is made of glass (such as quartz glass, etc.) or crystal, so as to ensure the spectral characteristics of the lampshade 512, so that the lampshade 512 can transmit not only visible light, but also ultraviolet light and infrared light, so as to ensure pulse Bactericidal effect of light source 51.

For example, the sealing member 513 is made of silicone to facilitate the soft connection while ensuring the sealing performance of the installation cavity; a part of the sealing member 513 is sleeved outside the end of the lampshade 512 so that the sealing member 513 can function as a soft connection. The function of protecting the lampshade 512 is to prevent the lampshade 512 from being in direct contact with other components, causing the lampshade 512 to break, etc., which is beneficial to improving the operational safety and service life of the pulse light source 51 .

For example, in the example of FIG. 8 , a mating groove 513b is formed on the side of the seal 513 facing the lampshade 512. The mating groove 513b is formed as an annular groove, and the lampshade 512 is inserted into the mating groove 513b.

Among them, the sterilization module 5 also includes a mounting bracket 52, and two seals 513 are installed on the mounting bracket 52 to realize the installation of the xenon lamp 511, to facilitate the overall stable installation of the pulse light source 51, and to avoid vibration caused by the operation of the air conditioner 100. The position of the xenon lamp 511 is changed, thereby improving the stability of the xenon lamp 511.

In some embodiments, as shown in Figure 8, at least one seal 513 is formed with a cavity connected to the installation cavity. The cavity has a through opening 513a. The cable of the xenon lamp 511 extends out of the cavity through the through opening 513a. Then the cavity The cavity can provide a certain path for the cable of the xenon lamp 511 to be led out. At the same time, the seal 513 can provide insulation protection for the cable of the xenon lamp 511 to avoid potential safety hazards during use. By preventing the cable of the xenon lamp 511 from being damaged in a small space, Heat shrink tube processing is performed to improve the safety of the installation of the pulse light source 22 .

For example, in the example of FIG. 8 , each seal 513 is formed with a cavity, and each cavity has a through port 513 a . One end of the xenon lamp 511 is a positive terminal, and the other end of the xenon lamp 511 is a negative terminal. The positive terminal and the negative terminal are provided with cables respectively. The cable at the positive end can extend into the cavity of one of the seals 511 and extend through the opening 513a of one of the seals 511, and the cable at the negative end can extend into the cavity of one of the seals 511, and Extend through the through opening 513a of one of the seals 511; or both the positive terminal cable and the negative terminal cable extend into the cavity of the same seal 511 and extend through the through opening 513a of the seal 511.

Among them, a sealant is provided in the cavity to further ensure the sealing of the installation cavity and avoid other foreign matter (such as Water vapor, etc.) invades the installation cavity. For example, sealant such as silicone rubber is poured into the cavity through the through hole 513a. At this time, the through hole 513a can be formed on the side wall of the sealing member 513 extending along the circumferential direction of the xenon lamp 511, and the sealing member 513 is installed on the lamp cover 512. Finally, if the opening 513a is not set upward, the seal 513 can be rotated so that the opening 513a is set upward, so that the sealant will not flow out during the glue filling process, which facilitates operation and ensures the workbench and lampshade 512 are secure. clean.

In some embodiments of the present application, as shown in Figures 1 and 6, the indoor air duct 1a and the fresh air duct 4a are separated, and the outdoor air enters the fresh air duct 4a through the fresh air inlet 4b. If the sterilization module 5 works, the sterilization Module 5 sterilizes the air in the fresh air duct 4a, and the sterilized outdoor air flows directly into the room from the fresh air outlet 4c; indoor air enters the indoor air duct 1a through the indoor air inlet 1c. If the sterilization module 5 works, the sterilization module 5 will The air in the indoor air duct 1a is sterilized, and the sterilized air flows directly into the room from the indoor air outlet 1c.

Of course, the application is not limited to this; in some embodiments, the air in the fresh air duct 4a can flow to the indoor air duct 1a through the fresh air outlet 4c, so that the outdoor air can be sterilized again by the sterilization module 5.

In some embodiments of the present application, as shown in Figures 7 and 15, the pulse light source 51 irradiates the fresh air fan 42 for sterilizing the fresh air fan 42, and the pulse light source 51 can sterilize the microorganisms attached to the fresh air fan 42. Disinfection to ensure that the fresh air delivered by the fresh air fan 42 is not contaminated by bacteria on the fresh air fan 42, thereby further ensuring the cleanliness of the fresh air delivered by the fresh air fan 42.

According to the above description of the pulse strong light sterilization mechanism in this application, it can be known that when the fresh air fan 42 is irradiated by the pulse strong light, the surface temperature of the microorganisms on the fresh air fan 42 will rise sharply, and the surface structure of the microorganisms will be completely destroyed and die. At the same time, the entire The photothermal action process is very short, and the irradiated fresh air fan 42 will not produce a temperature rise, thereby ensuring the normal operation of the fresh air fan 42 .

It can be understood that the pulse light source 51 can illuminate a part of the fresh air fan 42 to achieve sterilization, or the pulse light source 51 can illuminate the entire fresh air fan 42 to achieve sterilization; in other words, when the pulse light source 51 is working, at least part of the fresh air fan 42 is in the position of the pulse light source 51 Within the irradiation range of the output pulse strong light. It can be seen that the relative positions of the pulse light source 51 and the fresh air fan 42 have a certain degree of flexibility.

For example, in the examples of FIGS. 7 and 15 , the pulse light source 51 extends along the axial direction of the fresh air fan 42 , the pulse light source 51 is located on one axial side of the fresh air fan 42 , and the pulse light source 51 is arranged deviated from the central axis of the fresh air fan 42 ; Taking the pulse light source 51 located on the upper side of the central axis of the fresh air fan 42 as an example, the sterilization module 5 has an exit port, and the exit port is located on the bottom side of the sterilization module 5. The pulse strong light emitted by the pulse light source 51 is emitted through the exit port to illuminate. To at least the lower part of the fresh air fan 42.

In some embodiments of the present application, as shown in Figures 7 and 15, the fresh air module 4 also includes a purification unit 43. The purification unit 43 is provided on the air inlet side of the fresh air fan 42. The pulse light source 51 illuminates the purification unit 43 for use. When the purification unit 43 is sterilized, the pulse light source 51 can sterilize the microorganisms attached to the purification unit 43 to ensure the cleanliness of the purification unit 43.

It can be seen that in the direction of air flow in the fresh air duct 4a, the purification unit 43 is located on the upstream side of the fresh air fan 42. That is to say, the fresh air flowing to the fresh air duct 4a through the fresh air inlet 4b first flows through the purification unit 43 and then flows through The fresh air fan 42, so that the fresh air is purified by the purification unit 43 and then flows to the fresh air fan 42 to ensure that the fresh air flow passing through the fresh air fan 42 is relatively clean, and the pulse light source 51 can purify the purification unit 43, such as microorganisms on the purification unit 43, etc. Carry out sterilization to further improve the air quality, which is beneficial to extending the use time of the purification unit 43, avoiding frequent cleaning or replacement of the purification unit 43, and even eliminating the need to replace the purification unit 43 in the future.

According to the above description of the pulse strong light sterilization mechanism in this application, it can be known that when the purification unit 43 is irradiated by the pulse strong light, the surface temperature of the microorganisms on the purification unit 43 will rise sharply, and the surface structure of the microorganisms will be completely destroyed and die. At the same time, the entire The photothermal action process is very short, and the irradiated purification unit 43 will not produce a temperature rise, thereby ensuring the normal operation of the purification unit 43.

It can be understood that the pulse light source 51 can illuminate a part of the purification unit 43 to achieve sterilization, or the pulse light source 51 can illuminate the entire purification unit 43 to achieve sterilization; in other words, when the pulse light source 51 is working, at least part of the purification unit 43 is in the position of the pulse light source 51 Within the irradiation range of the output pulse strong light. It can be seen that the relative positions of the pulse light source 51 and the purification unit 43 have certain flexibility.

For example, in the examples of FIGS. 7 and 15 , the pulse light source 51 extends along the axial direction of the fresh air fan 42 , the pulse light source 51 is located on one axial side of the fresh air fan 42 , and the pulse light source 51 is arranged deviated from the central axis of the fresh air fan 42 . Taking the pulse light source 51 located on the upper side of the central axis of the fresh air fan 42 as an example, the sterilization module 5 has an exit port, and the exit port is located on the bottom side of the sterilization module 5. The pulse strong light emitted by the pulse light source 51 is emitted through the exit port to illuminate the At least the lower part of the fresh air fan 42; the arrangement of the purification unit 43 at this time: as shown in Figure 7, the purification unit 43 is located between the fresh air fan 42 and the pulse light source 51, so that the purification unit 43 and the pulse light source 51 are located at the fresh air fan 42 on the same axial side; or, as shown in Figure 15, the purification unit 43 is located on the radial side of the fresh air fan 42, and in the up and down direction, the purification unit 43 is located below the fresh air fan 42.

In some embodiments of the present application, as shown in Figures 10 and 15, the housing 41 is formed with a pull-out opening 411, and the purification unit 43 is detachably provided on the housing 41 through the pull-out opening 411 to facilitate cleaning or replacement. Unit 43 improves the user's operational convenience, is conducive to improving the adaptability of the air conditioner 100, and expanding the applicable scope of the air conditioner 100. For example, the air conditioner 100 can be used in usage scenarios with a large amount of dust and other pollutants in the outdoor environment.

In some embodiments of the present application, as shown in Figures 7 and 15, the purification unit 43 includes a filter. The filter can filter, remove dust, etc., on the air flowing to the fresh air duct 4a. The filter and the fresh air fan 42 are located in the sterilization module. 5 on the same side, it is conducive to a more compact arrangement of the filter screen and the fresh air fan 42, improving the utilization rate of the internal space of the fresh air module 4, making the fresh air module 4 compact, and at the same time, it is conducive to the sterilization module 5 to sterilize the filter screen and the fresh air fan 42 at the same time. , improve the sterilization efficiency of the air conditioner 100.

Among them, the pulsed strong light released by the sterilization module 5 kills bacteria and other microorganisms filtered by the filter, ensuring that the The cleaning of the filter eliminates the need to replace the filter during subsequent use, saving user costs.

For example, the filter can be a HEPA (High efficiency particulate air Filter) network. The HEPA network can effectively filter smoke, dust, bacteria and other pollutants in the airflow to ensure the cleanliness of the air flowing to the fresh air fan 42.

For example, outdoor air enters the fresh air duct 4a from the fresh air inlet 4b and passes through the HEPA net of the purification unit 43. The HEPA net blocks bacteria from entering the fresh air duct 4a, and the bacteria filtered by the HEPA net are disinfected by the sterilization module 5 to ensure that it flows to the fresh air fan. 42, the air is cleaned, and then the fresh air fan 42 sends the fresh air sterilized by the sterilization module 5 into the room through the fresh air outlet 4c, realizing the circulation and ventilation between the indoor air and the outdoor air, and purifying the air sent from the outside into the room. Ensure the freshness of indoor air and improve user comfort.

In some embodiments of the present application, as shown in Figures 7 and 15, the fresh air fan 42 includes a centrifugal fan, and the purification unit 43 is provided on the axial side or the radial side of the centrifugal fan, so that the purification unit 43 has a variety of The installation position can better adapt to the layout of the fresh air module 4 and facilitate meeting actual differentiated needs.
