Description

Technical Field

[0001] This application relates to the field of vehicle air conditioning technology, and in particular to a self-cleaning device, a vehicle air conditioner, and a mobile terminal. Background Technology

[0002] An automotive air conditioning system is a ventilation device used to adjust and control the temperature, humidity, air cleanliness, and airflow inside a car cabin to optimal levels. This provides a comfortable riding environment for passengers, reduces travel fatigue, creates favorable working conditions for the driver, and plays a crucial role in ensuring safe driving.

[0003] However, during the use of car air conditioning, due to prolonged use or poor air quality inside the car, the cleanliness of the air conditioning system may deteriorate, further weakening its air conditioning effect.

[0004] Therefore, a feasible solution is urgently needed to achieve self-cleaning of automotive air conditioning systems. Utility Model Content

[0005] This application provides a self-cleaning device, a vehicle air conditioner, and a mobile terminal, which can realize the self-cleaning of the car air conditioner.

[0006] In a first aspect, embodiments of this application provide a self-cleaning device applied to a vehicle's in-vehicle air conditioning system. The self-cleaning device includes: a control module, an evaporator, a heat-conducting module, a heating module, a compressor, and a blower. The control module is connected to the heating module, compressor, and blower respectively. The compressor is connected to the evaporator, and the heat-conducting module is thermally connected to the heating module. The blower, evaporator, and heat-conducting module are arranged sequentially. The control module controls the compressor to operate, causing impurities to condense on the surface of the evaporator. The control module controls the heating module to generate heat, which is then conducted to the heat-conducting module. The control module controls the blower to blow air along the direction from the heat-conducting module to the evaporator. The hot airflow after passing through the heat-conducting module is then blown onto the surface of the evaporator, causing the condensed impurities on the evaporator surface to be blown away.

[0007] The self-cleaning device provided in this application embodiment lowers the temperature of the refrigerant inside the evaporator by controlling the compressor, thereby reducing the temperature of the evaporator surface and causing impurities to condense on the evaporator surface. Then, the heating module and blower work together to generate a hot airflow that blows away the condensed impurities on the evaporator surface, achieving the cleaning purpose. In the above embodiment, the compressor's operation causes impurities / dust on the evaporator surface to condense, while the hot air generated by the heating module and blower helps to remove the condensed impurities from the evaporator surface, thus achieving the cleaning purpose. This cleaning method is not only simple and efficient but can also be fully automated, providing passengers with a good user experience.

[0008] Optionally, the impurities on the evaporator may include dust or rust.

[0009] Optionally, the blower, heat transfer module, and evaporator can be positioned in the following order: heat transfer module, blower, and evaporator.

[0010] In one possible implementation, when the vehicle's air conditioning is in self-cleaning mode, the airflow from the blower enters the self-cleaning device through a first air vent inside the vehicle's cabin and exits outside the vehicle through a second air vent outside the cabin.

[0011] In the above embodiment, the airflow generated by the blower enters the self-cleaning device through the first air vent and is discharged outside the vehicle through the second air vent outside the vehicle cabin. This can clean impurities on the evaporator while promptly removing them from the vehicle along with the airflow, thereby preventing impurities from being blown into the vehicle or from accumulating inside the self-cleaning device.

[0012] In another possible implementation, the self-cleaning device further includes a UV lamp. The position of the UV lamp is correlated with the position of the evaporator, such that the surface of the evaporator is within the irradiation range of the UV lamp. A control module controls the UV lamp to emit ultraviolet light to disinfect and sterilize the surface of the evaporator.

[0013] In the above embodiments, the self-cleaning device also includes a UV lamp, and the irradiation range of the UV lamp includes the surface of the evaporator. Therefore, the ultraviolet light emitted by the UV lamp can disinfect bacteria on the surface of the evaporator, achieving the purpose of self-cleaning. It can be understood that by using a UV lamp to disinfect bacteria on the surface of the evaporator, a deep cleaning effect can be achieved, minimizing the harm of bacteria to the human body.

[0014] In another possible implementation, the self-cleaning device further includes a negative ion generator. The negative ion generator and the blower are respectively positioned on opposite sides of the evaporator along a first direction. A control module controls the negative ion generator to generate negative air ions, which are then blown onto the surface of the evaporator by hot air to disinfect and sterilize the evaporator surface.

[0015] In the above embodiments, the self-cleaning device also includes a negative ion generator, and the negative ions generated by the negative ion generator can reach the surface of the evaporator with the air generated by the blower, thereby achieving the effect of disinfection and sterilization. It can be understood that by using the negative ion generator to disinfect bacteria on the surface of the evaporator, a deep cleaning effect can be achieved, so as to minimize the harm of bacteria to the human body.

[0016] Optionally, the negative ion generator and the blower are located on the same side of the evaporator, so that the negative ions provided by the negative ion generator can reach the surface of the evaporator along with the airflow.

[0017] In another possible implementation, the surface of the evaporator is coated with a zinc oxide layer. This zinc oxide coating releases zinc ions into the aqueous medium, thereby disinfecting and sterilizing the evaporator surface.

[0018] In the above embodiments, by applying a zinc oxide coating to the surface of the evaporator, the zinc ions released by the zinc oxide coating can effectively disinfect bacteria on the evaporator surface, thereby improving the cleaning effect.

[0019] In another possible implementation, a first button is provided in the vehicle's cabin. This first button responds to a user's first operation, triggering the control function of the control module.

[0020] In the above embodiment, by setting a first button in the vehicle's cabin, the user can trigger the control function of the control module through the first button, so that the user can choose to clean the evaporator surface at an appropriate time according to their needs.

[0021] In another possible implementation, the control module is used to control the operation of the compressor, including: the control module is used to acquire a target dust content on the evaporator surface; and the control module is used to control the compressor to operate at a target speed and target temperature when the target dust content is greater than a first threshold.

[0022] In the above embodiments, the control module is used to obtain the target dust content on the surface of the evaporator on the one hand, and to control the compressor to compress at the target speed and target temperature when the target dust content is greater than the first threshold, so as to reduce the temperature of the refrigerant inside the evaporator, thereby causing the impurities on the surface of the evaporator to condense, thereby achieving the effect of automatically condensing the impurities on the surface of the evaporator, and thus achieving the purpose of automatically cleaning the impurities on the surface of the evaporator.

[0023] In another possible implementation, the control module is used to obtain the target dust content on the evaporator surface, including: the control module is used to obtain one or more of the following information: blower airflow, PM2.5 concentration, mileage of the vehicle since the last disinfection and sterilization, and cumulative operating time of the compressor since the last disinfection and sterilization. The control module is used to determine the target dust content on the evaporator surface based on one or more of the above information.

[0024] In the above embodiments, the control module determines the target dust content on the evaporator surface based on one or more of the following factors: blower airflow, PM2.5 concentration, vehicle mileage since the last disinfection, and cumulative compressor operating time since the last disinfection. The blower airflow can refer to the historical airflow since the last disinfection or the instantaneous airflow. Similarly, the PM2.5 concentration can refer to the historical PM2.5 concentration since the last disinfection or the instantaneous PM2.5 concentration. It is understood that the blower airflow, PM2.5 concentration, vehicle mileage, and cumulative compressor operating time all affect the impurity content on the evaporator surface. Therefore, by using these factors, the target dust content on the evaporator surface can be determined relatively accurately, thereby achieving the purpose of automatic cleaning.

[0025] In another possible implementation, the control module is used to determine the target dust content on the evaporator surface based on one or more pieces of information, including: determining a first dust content based on the blower's airflow and / or PM2.5 concentration, and / or determining a second dust content based on the vehicle's mileage since the last disinfection and sterilization, and / or determining a third dust content based on the compressor's cumulative operating time since the last disinfection and sterilization. The control module is used to determine the target dust content based on the first dust content and / or the second dust content and / or the third dust content.

[0026] In the above embodiments, the control module can first determine one or more of the first dust content, the second dust content, or the third dust content, and then determine the target dust content. This allows the control module to comprehensively consider multiple factors to determine the target dust content, so that the target dust content can accurately reflect the amount of dust on the evaporator surface. Based on the determined target dust content, the control module can control the relevant modules to complete the self-cleaning operation.

[0027] In another possible implementation, the control module is used to control the heating module to generate heat, including: the control module is used to acquire a target amount of condensate on the evaporator surface. The control module is used to control the heating module to generate heat when the target amount of condensate is greater than a second threshold.

[0028] In the above embodiments, the control module determines whether to activate the heating module to generate heat by judging whether the target condensate volume on the evaporator surface is greater than a second threshold, thereby achieving the effect of removing condensate from the evaporator surface. For example, when the target condensate volume is greater than the second threshold, the control module controls the heating module to generate heat, and works with the heat conduction module and blower to transfer the heat to the evaporator surface, thereby achieving the purpose of removing condensate.

[0029] In another possible implementation, the control module is used to acquire the target condensate volume on the evaporator surface, including: acquiring one or more of the following information: humidity of the evaporator surface, temperature of the evaporator surface, and dew point temperature. The control module is used to determine the target condensate volume on the evaporator surface based on one or more of the above information.

[0030] It is understandable that when the dew point temperature is higher than the temperature of the evaporator surface and the humidity of the evaporator surface meets the requirements, condensation will form on the evaporator surface. Therefore, by acquiring one or more of the humidity, temperature, or dew point temperature of the evaporator surface, the control module can accurately determine the target amount of condensation on the evaporator surface. This allows the heating module and blower to remove the condensation when the amount of condensation is too high, thereby improving the working performance of the evaporator.

[0031] In another possible implementation, the control module is used to control the blower to blow air in the direction from the heat-conducting module to the evaporator, including: the control module is used to control the blower to blow air in the direction from the heat-conducting module to the evaporator when the target dust content on the evaporator surface is greater than a first threshold and / or the target condensate content on the evaporator surface is greater than a second threshold.

[0032] In the above embodiments, when the target dust content on the evaporator surface is greater than the first threshold and / or the target condensate content on the evaporator surface is greater than the second threshold, the blower is controlled to blow air along the direction from the heat conduction module to the evaporator, so that the hot air can remove the condensed impurities and / or condensate on the evaporator surface in a timely manner, thereby improving the working performance of the evaporator.

[0033] In another possible implementation, the control module is also used to control the activation of the surface disinfection and sterilization function of the evaporator when the target dust content on the evaporator surface is greater than a first threshold and / or the number of blowers blowing air along the direction from the heat conduction module to the evaporator is greater than a third threshold.

[0034] In the above embodiments, when the target dust content on the evaporator surface is greater than the first threshold and / or the number of blowers blowing air along the direction from the heat conduction module to the evaporator is greater than the third threshold, the control module controls the activation of the disinfection and sterilization function on the evaporator surface, thereby achieving the purpose of regular deep cleaning to minimize the harm of bacteria to the human body.

[0035] Secondly, embodiments of this application provide a vehicle air conditioner, including the self-cleaning device described in the first aspect and any possible implementation.

[0036] Thirdly, this application provides a mobile terminal that includes the self-cleaning device described in the first aspect and any possible implementation, or includes the vehicle air conditioner described in the second aspect.

[0037] Optionally, the mobile terminal can be a means of transportation, such as a car, truck, aircraft, drone, slow transport vehicle, spacecraft, or ship, or any other possible means of transportation used in any possible scenario. This application embodiment does not limit this. Attached Figure Description

[0052] It should be understood that in this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0053] In the description of this application, the terms "center," "upper," "lower," "vertical," "horizontal," "inner," "outer," "left," and "side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0055] Car air conditioning is a crucial comfort feature in automobiles. It precisely regulates the interior temperature to significantly enhance the passenger experience. For example, whether commuters are seeking respite from the scorching sun or freezing winter winds, or road trippers are navigating long distances through urban and rural areas, it effectively improves the in-car microclimate, enhancing passenger comfort and allowing drivers to maintain optimal driving conditions, thus ensuring road safety. However, since car air conditioning systems are located inside vehicles, over time, dust, condensation, and even bacteria can accumulate on the evaporator. This can negatively impact the air conditioning's performance and, more importantly, the dust and bacteria within the system can potentially harm human health.

[0056] In view of this, this application provides a self-cleaning device for use in vehicle air conditioning, which can automatically clean dust, water droplets or bacteria inside the vehicle air conditioning unit, ensuring that the vehicle air conditioning unit can work normally and efficiently.

[0057] Next, combine Figures 1 to 4 The self-cleaning device provided in this application will be described exemplarily.

[0058] Please see Figure 1 , Figure 1 A schematic diagram of the first self-cleaning device provided in this application.

[0059] like Figure 1 As shown, the self-cleaning device 100 includes an evaporator 101, a heat conduction module 102, a heating module 103, a compressor 104, a blower 105, an ultraviolet lamp 106, a negative ion generator 107A, a negative ion generator 107B, and dampers 108A to 108H.

[0060] In addition, the self-cleaning device 100 also includes a control module ( Figure 1 (Not shown), the control module is connected to the heating module 103, the compressor 104 and the blower 105, and is used to control the operation of the heating module 103, the compressor 104 and the blower 105.

[0061] The negative ion generator 107A and negative ion generator 107B can refer to two components of a single negative ion generator or two negative ion generators. This application does not limit the number of negative ion generators in the self-cleaning device 100.

[0062] Optionally, the control module is also connected to the ultraviolet lamp 106, the negative ion generator 107A, and the negative ion generator 107B, and is used to control the operation of the ultraviolet lamp 106, the negative ion generator 107A, and the negative ion generator 107B.

[0063] The evaporator 101 is a heat exchanger in the air conditioning system responsible for converting the refrigerant from a liquid to a gaseous state. By absorbing heat from the surrounding air, the refrigerant evaporates and absorbs heat, thereby cooling or heating the air. The evaporator 101 has one or more functions, including cooling, dehumidification, or auxiliary heating.

[0064] The heat conduction module 102 is used to transfer the heat generated by the heating module 103 to heat the air around the heat conduction module 102, for example, to heat the air temperature so that the wind generated by the blower 105 forms warm air after passing through the hot air.

[0065] The heating module 103 is used to generate heat. For example, the heating module 103 is a heating element made of a thermistor material with a positive temperature coefficient (PTC). Alternatively, the heating module 103 can also be a heating element made of a heating wire. It should be noted that... Figure 1 The heating module 103 shown is attached to the heat-conducting module 102, and is only used as an example to illustrate the relative positional relationship between the heating module 103 and the heat-conducting module 102. In some implementations, the heating module 103 may be disposed outside the heat-conducting module 102, or it may be disposed inside the heat-conducting module 102. This application embodiment does not limit the relative positional relationship between the heating module 103 and the heat-conducting module 102, nor should it be considered as such. Figure 1 The relative positional relationship between the heating module 103 and the heat conduction module 102 in the embodiments of this application constitutes a limitation.

[0066] The main function of compressor 104 is to compress the refrigerant to increase its pressure and temperature, enabling it to circulate within the system and facilitate heat transfer and exchange. It should be noted that... Figure 1 The compressor 104 and evaporator 101 shown are connected, and this is only an example illustrating their relative position. In some implementations, the compressor 104 can be connected to the evaporator 101 via a four-way valve, a condenser, or a throttling element. This application does not limit the relative position of the compressor 104 and evaporator 101, nor should it be considered as such. Figure 1 The relative positional relationship between the compressor 104 and the evaporator 101 in the embodiments of this application constitutes a limitation.

[0067] The blower 105 is used to drive airflow to generate airflow, thereby promoting air circulation and improving heat exchange efficiency. Optionally, the blower 105 can blow air in a first direction and a second direction, which are two completely opposite directions.

[0068] Ultraviolet lamp 106 is used to generate ultraviolet light to disinfect viruses and bacteria. For example, the ultraviolet light emitted by ultraviolet lamp 106 is used to disinfect viruses or bacteria on the surface of the evaporator.

[0069] Negative ion generators 107A and 107B are used to generate negative ions, which have the effect of eliminating viruses and bacteria. For example, the negative ions generated by negative ion generators 107A and 107B are used to eliminate viruses and bacteria on the evaporator 101.

[0070] The dampers 108A to 108H serve to either guide or block airflow. For example, when the damper is closed, it blocks airflow; when the damper is open, it guides airflow. The degree to which the damper is open also affects the airflow volume. Optionally, damper 108A is an internal circulation damper, and damper 108B is an external circulation damper. That is, the air flowing into / out of damper 108A is the air inside the vehicle's cabin, and the air flowing into / out of damper 108B is the air outside the vehicle. Air damper 108C is a damper for the internal circulation channel, used to control the airflow of the internal circulation channel; air dampers 108D and 108H are bypass ventilation dampers, used to guide / block the airflow between the internal circulation channel and the external circulation channel; air dampers 108E to 108G are also internal circulation dampers. For example, air damper 108E is the damper near the driver's seat, air damper 108F is the damper near the passenger seat, and air damper 108G is the damper for the rear seats. It should be noted that the number and shape of the above-mentioned dampers are exemplary and do not constitute a limitation on the solution of this application. For example, the shape of the dampers can also be louvered, circular, or rectangular, etc., and the number of dampers can also be 10, 11, or 12, etc.

[0071] It should be noted that the self-cleaning device provided in this application may include any one or more of the above-mentioned ultraviolet lamp 106, negative ion generator 107A, and negative ion generator 107B, and should not be used as a pretext. Figure 1 The embodiments of this application constitute limitations.

[0072] In one possible implementation, external circulation ventilation or internal circulation ventilation can be formed by controlling the damper and blower 105.

[0073] For example, the blower 105 works in coordination with the dampers 108A to 108H to allow airflow to enter the self-cleaning device 100 from the dampers 108E and 1088F, and then pass through the heat conduction module 102 to form hot air, which then passes through the negative ion generator 107A and the evaporator 101 in sequence, and finally flows out from the damper 108B to form an external circulation.

[0074] For example, the blower 105 works in coordination with the dampers 108A to 108H to allow airflow to enter the self-cleaning device 100 from the damper 108G, and form hot air through the heat conduction module 102, and then pass through the negative ion generator 107B, the evaporator 101, and the damper 108C in sequence, and finally flow out from the damper 108A to form an internal circulation.

[0075] Please see Figure 2 , Figure 2 A schematic diagram of the second self-cleaning device provided in this application.

[0076] It is understood that the self-cleaning device in the embodiments of this application can be regarded as described above. Figure 1 Reasonable variations or additions to the embodiments in this application; or, it is understood that the self-cleaning device in the embodiments of this application can also be regarded as an embodiment that can be implemented independently, and this application does not limit it.

[0077] Understandable, Figure 2 And subsequent Figure 3 , Figure 4 The self-cleaning device shown is Figure 1 The difference in the self-cleaning device shown is the change in the position of the blower.

[0078] like Figure 2 As shown, the self-cleaning device 200 includes an evaporator 101, a heat conduction module 102, a heating module 103, a compressor 104, an ultraviolet lamp 106, a negative ion generator 107A, a negative ion generator 107B, dampers 108A to 108H, a blower 109A, a blower 109B, etc.

[0079] In addition, the self-cleaning device 200 also includes a control module ( Figure 2(Not shown) The control module is connected to the heating module 103, compressor 104, blower 109A and blower 109B, and is used to control the operation of the heating module 103, compressor 104, blower 109A and blower 109B.

[0080] In this application, negative ion generator 107A and negative ion generator 107B can refer to two components of a single negative ion generator, or to two separate negative ion generators. The number of negative ion generators in the self-cleaning device 100 is not limited in this application. Similarly, blower 109A and blower 109B can refer to two components of a single blower, or to two separate blowers. The number of blowers in the self-cleaning device 100 is not limited in this application. Further details regarding the self-cleaning device 200 can be found above. Figure 1 The relevant descriptions will not be repeated here.

[0081] It is understandable that blowers 109A and 109B are located in two different circulating air ducts, with blower 109A located in the external circulating air duct and blower 109B located in the internal circulating air duct.

[0082] It is also understandable that blowers 109A and / or 109B blow air through the heat-conducting module 102 to form hot air, which is then blown onto the surface of the evaporator 101. Furthermore, the airflow generated by blowers 109A and / or 109B can also carry negative ions generated by negative ion generators 107A and 107B to the surface of the evaporator 101 to disinfect viruses and bacteria on the surface of the evaporator 101.

[0085] Understandable, Figure 3 and Figure 2 The difference in the self-cleaning device shown is that the relative positions of the negative ion generator and the heat conduction module are different.

[0086] For example, Figure 2 In the self-cleaning device 200 shown, the negative ion generators 107A / 107B are located between the heat-conducting module 102 and the evaporator 101.

[0089] Understandable, Figure 4 and Figure 3 The difference in the self-cleaning device shown is that the relative positions of the heat-conducting module and the blower are different.

[0090] For example, Figure 3 In the self-cleaning device 300 shown, the heat-conducting module 102 is located between the blower 109A / 109B and the evaporator 101.

[0092] It should be understood that, based on the above Figures 1 to 4 Any new self-cleaning device obtained by reasonably modifying, supplementing, or combining the self-cleaning device in the present application shall fall within the scope of protection of this application.

[0093] Please see Figure 5 , Figure 5 A schematic diagram of another self-cleaning device provided in this application.

[0094] like Figure 5As shown, the self-cleaning device 500 includes a control module 501, an evaporator 502, a heat conduction module 503, a heating module 504, a compressor 505, and a blower 506.

[0095] Optionally, the self-cleaning device 500 may also include an ultraviolet lamp 507 and / or a negative ion generator 508.

[0096] The control module 501, evaporator 502, heat conduction module 503, heating module 504, compressor 505, blower 506, ultraviolet lamp 507, and negative ion generator 508 can all refer to the above. Figures 1 to 4 The description of the corresponding content, for example, control module 501 could be Figures 1 to 4 The control module described in any of the accompanying drawings. For example, blower 506 could be... Figures 1 to 4 The blower described in any of the accompanying drawings. For example, UV lamp 507 could be... Figures 1 to 4 The ultraviolet lamp described in any of the attached figures.

[0097] The control module 501 is connected to the heating module 504, the compressor 505, and the blower 506 respectively. For example, the control module 501 is connected to the heating module 504, the compressor 505, and the blower 506 respectively via electrical connection. For another example, the control module 501, the heating module 504, the compressor 505, and the blower 506 all include wireless communication units, and the control module 501 can be connected to the heating module 504, the compressor 505, and the blower 506 respectively via wireless communication.

[0098] The heat-conducting module 503 is connected to the heating module 504. For example, the heat-conducting module 503 and the heating module 504 are connected by bonding, so that the heat generated by the heating module 504 can be conducted to the heat-conducting module 503. Alternatively, the heat-conducting module 503 can be connected to the heating module 504 by nesting, mechanical connection, or welding.

[0099] Compressor 505 is connected to evaporator 502, for example, via piping, manifold connection, etc. It is understood that the connection between compressor 505 and evaporator 502 is for the transfer of refrigerant. In some implementations, compressor 505 may be connected to evaporator 502 via a four-way valve, condenser, or throttling element.

[0100] In one possible implementation, the blower 506, evaporator 502, and heat conduction module 503 are arranged in sequence, so that the airflow generated by the blower 506 can form a hot airflow after passing through the heat conduction module 503, and then blow the hot airflow to the surface of the evaporator 502.

[0101] For example, please see Figure 1The heat conduction module 102, evaporator 101, and blower 105 are arranged sequentially from right to left in the direction shown in the figure. When the blower 105 blows air in the direction shown in the figure from right to left, the airflow generated by the blower 105 can pass through the heat conduction module 102 to form a hot airflow, which will then be blown to the surface of the evaporator 101.

[0102] It is understandable that the positional relationship between the blower 506, the evaporator 502, and the heat transfer module 503 can depend on the airflow direction generated by the blower 506. As long as the heat transfer module 503 is located upstream of the evaporator 502 in the airflow generated by the blower 506, the hot airflow can be blown to the surface of the evaporator 101.

[0103] For example, please see Figure 2 The blower 109A, the heat conduction module 102, and the evaporator 101 are arranged sequentially from right to left in the direction shown in the figure. This allows the airflow generated by the blower 109A to pass through the heat conduction module 102 and form a hot airflow, which in turn blows onto the surface of the evaporator 101 when the blower 109A blows air in the direction shown in the figure from right to left.

[0104] For example, please see Figure 3 The blower 109A, the heat conduction module 102, and the evaporator 101 are arranged sequentially from right to left in the direction shown in the figure. This allows the airflow generated by the blower 109A to pass through the heat conduction module 102 and form a hot airflow, which in turn blows onto the surface of the evaporator 101 when the blower 109A blows air in the direction shown in the figure from right to left.

[0105] For example, please see Figure 4 The heat conduction module 102, blower 109A, and evaporator 101 are arranged sequentially from right to left in the direction shown in the figure. This allows the heat conduction module 102 to heat the airflow first when the blower 109A blows air in the direction shown in the figure from right to left. The hot airflow passes through the blower 109A first and then reaches the surface of the evaporator 101.

[0106] Control module 501 controls the operation of compressor 505 to lower the temperature of the refrigerant inside the evaporator, thereby causing impurities to condense on the surface of evaporator 502. It can be understood that the compressor 505 compresses the gas, increasing its internal energy. During the evaporation and vaporization process of this gas entering evaporator 502, it absorbs a large amount of heat, thus lowering the surface temperature of evaporator 502 and causing impurities to condense on its surface. Optionally, the gas is a gaseous refrigerant. Please refer to... Figure 1The control module can control the compressor 104 to compress the gas, and transmit the compressed gas to the evaporator 101 through the pipeline. After the gas enters the evaporator 101, it evaporates, causing impurities to condense on the surface of the evaporator 101. Figures 2 to 4 The implementation process is similar and will not be described in detail here.

[0107] The control module 501 is used to control the heating module 504 to generate heat, and the heat generated by the heating module 504 is conducted to the heat conduction module 503. For example, the control module 501 can control the heating module 504 to generate heat through mechanical switches, relays, microcontrollers, or variable resistors.

[0108] The control module 501 controls the blower 506 to blow air along the direction from the heat-conducting module 503 to the evaporator 502. The hot air from the heat-conducting module 503 is then blown onto the surface of the evaporator 502, so that condensed impurities on the surface of the evaporator 502 are blown away. (Please refer to...) Figure 1 The control module can control the blower 105 to blow air from the left direction as shown in the figure, and control the heating module 103 to generate heat. After the airflow passes through the heat conduction module 102, it will form a hot airflow. Furthermore, the hot airflow will reach the surface of the evaporator 101, thereby blowing away the condensed impurities on the surface of the evaporator 101. Figures 2 to 4 The implementation process is similar and will not be described in detail here.

[0109] In one possible implementation, when the vehicle's air conditioning is in self-cleaning mode, the airflow from the blower enters the self-cleaning device through a first air vent inside the vehicle's cabin and exits outside the vehicle through a second air vent outside the cabin.

[0110] The self-cleaning mode of the vehicle air refers to the process by which the vehicle air conditioner uses the self-cleaning device provided in this application to automatically clean the surface of the evaporator.

[0111] The first air vent can be an air vent located inside the vehicle's cabin, to Figure 1 For example, the first damper can be damper 108E, damper 108F, or damper 108G.

[0112] The second air damper can be an external circulation damper, continuing with... Figure 1 For example, the second damper can be damper 108B.

[0113] For example, with Figure 1 For example, with dampers 108B, 108E, and 108F in the open state and the remaining dampers in the closed state, the airflow generated by blower 105 flows to the left as shown in the diagram. The airflow from blower 105 enters the self-cleaning device 100 through the first damper inside the vehicle's cabin and exits outside the vehicle through the second damper outside the cabin. Specifically... Figure 6 As shown.

[0114] For example, with Figure 2 For example, with dampers 108B, 108E, and 108F in the open state and the remaining dampers in the closed state, the airflow generated by blower 109A flows to the left as shown in the diagram. The airflow from blower 109A enters the self-cleaning device 100 through the first damper inside the vehicle's cabin and exits outside the vehicle through the second damper outside the cabin. Specifically... Figure 7 As shown.

[0115] As can be seen, the above method can blow the condensed impurities on the surface of the evaporator out of the vehicle, preventing the impurities from being carried into the vehicle by the airflow and thus endangering the health of passengers.

[0116] In another possible implementation, the self-cleaning device 500 also includes an ultraviolet lamp 507.

[0117] The position of the ultraviolet lamp 507 is associated with the position of the evaporator 502, so that the surface of the evaporator 502 is within the irradiation range of the ultraviolet lamp 507. The control module 501 is used to control the ultraviolet lamp 507 to emit ultraviolet light, so as to disinfect and sterilize the surface of the evaporator 502.

[0118] Please see Figure 1 The ultraviolet lamp 106 is located above the evaporator 101, so that the surface of the evaporator 101 is within the irradiation range of the ultraviolet lamp 507. Figures 2 to 4 Similar to Figure 1 This will not be elaborated further here. It should be noted that this application does not limit the specific positional relationship between the ultraviolet lamp 507 and the evaporator 502; any surface of the evaporator 502 within the irradiation range of the ultraviolet lamp 507 is within the protection scope of this application. Of course, this application does not limit the number of ultraviolet lamps 507; for example, the number of ultraviolet lamps 507 can be 1, 2, or 3. Optionally, the control module 501 can control the frequency, intensity, etc., of the ultraviolet light emitted by the ultraviolet lamp 507.

[0119] In another possible implementation, the self-cleaning device 500 also includes a negative ion generator 508.

[0120] The negative ion generator 508 and the blower 506 are respectively arranged on opposite sides of the evaporator 502 along a first direction. The control module 501 is used to control the negative ion generator 508 to generate negative air ions, which are then blown onto the surface of the evaporator 502 by hot air to disinfect and sterilize the surface of the evaporator 502. The first direction is the direction in which the negative ion generator 508 points towards the blower 506.

[0121] Please see Figure 1The first direction, for example, is the direction from right to left as shown in the diagram. The negative ion generators 107A / 107B and the blower 105 are respectively arranged on opposite sides of the evaporator 101 along the first direction. The control module can control the negative ion generators 107A / 107B to generate negative air ions, control the heating module 103 to generate heat, and control the blower to generate airflow in the first direction. This causes the airflow to become hot airflow after passing through the heat conduction module 102. The hot airflow will also blow the negative air ions generated by the negative ion generators 107A / 107B onto the surface of the evaporator 101 to achieve disinfection and sterilization of the surface of the evaporator 101.

[0122] Optionally, the blower 506 and the negative ion generator 508 can also be located on the same side of the evaporator 502, such as... Figure 2 As shown, blowers 109A / 109B and negative ion generators 107A / 107B are both located on the right side of evaporator 101. Figure 3 and Figure 4 Similarly, I will not go into details here.

[0123] In another possible implementation, the surface of the evaporator 502 is provided with a zinc oxide coating.

[0124] The zinc oxide coating is used to release zinc ions in an aqueous medium to achieve surface disinfection and sterilization of the evaporator 502.

[0125] For example, when the surface of evaporator 502 has a certain humidity, the zinc oxide coating on the surface of evaporator 502 will automatically release zinc ions to disinfect and sterilize the surface of evaporator 502.

[0126] In another possible implementation, a first button is located inside the vehicle's cabin.

[0127] The first button responds to the user's first operation and triggers the control function of the control module.

[0128] Optionally, pressing the first button can activate the self-cleaning function, and the self-cleaning device mentioned above can perform the self-cleaning function. Optionally, pressing the first button can also manually control the immediate start of the cleaning mode; this embodiment of the application does not limit this.

[0129] The first button can be a physical button or a virtual control on the vehicle's screen. For example... Figure 8As shown, the first button can be a physical button 801 on the armrest or a virtual control 803 on the central control screen 802. Of course, the first button can also be a physical button on the door, steering wheel, instrument panel, etc., or it can be a virtual control on other screens in the vehicle, such as virtual controls on the passenger entertainment screen or rear entertainment screen. The first operation can be pressing, rotating, flicking, sliding, or clicking, etc., and this application embodiment does not limit this.

[0130] Optionally, users can also trigger the control functions of the control module through voice interaction or gesture commands, and this application embodiment does not limit this.

[0131] The above content combined Figures 1 to 8 The structure of the self-cleaning device in this application has been described exemplarily. Next, the working process of the self-cleaning device is also illustrated, such as... Figure 9 or Figure 10 As shown.

[0132] Please see Figure 9 In one possible implementation, the control module 501 is used to obtain the target dust content on the surface of the evaporator 502.

[0133] For example, the control module 501 is used to acquire one or more of the following information: the air volume of the blower 506, the PM2.5 concentration, the mileage of the vehicle since the last disinfection and sterilization, and the cumulative operating time of the compressor 505 since the last disinfection and sterilization. Wherein:

[0134] The air volume of blower 506 can refer to the total air volume generated by blower 506 after the last disinfection and sterilization. For example, by integrating the air volume output by blower 506 over time based on the operating time of blower 506, the total air volume generated by blower 506 after the last disinfection and sterilization can be obtained. The air volume of blower 506 can also refer to the air volume generated by blower 506 in a recent period, such as 1 day, 2 days, or 3 days, etc. This application does not limit this.

[0135] PM2.5 concentration can refer to the historical PM2.5 concentration in the area where the vehicle is located after the last disinfection and sterilization. PM2.5 concentration can also refer to the PM2.5 concentration in a recent period, such as 1 day, 2 days, or 3 days. This application does not limit this.

[0136] The control module 501 is used to determine the target dust content on the surface of the evaporator 502 based on one or more of the aforementioned information. For example, the correspondence between one or more of the following—the airflow of the blower 506, PM2.5 concentration, the mileage of the vehicle since the last disinfection, or the cumulative operating time of the compressor 505 since the last disinfection—and the target dust content can be pre-set experimentally. Based on this correspondence, the control module 501 can determine the target dust content on the surface of the evaporator 502. For example, the target dust content on the surface of the evaporator 502 can also be determined based on one or more of the aforementioned information using machine learning or artificial intelligence.

[0137] The control module 501 is also used to determine a first dust content based on the airflow of the blower 506 and / or the PM2.5 concentration, and / or, based on the mileage of the vehicle since the last disinfection and sterilization, to determine a second dust content, and / or, based on the cumulative operating time of the compressor 505 since the last disinfection and sterilization. The control module 501 is also used to determine a target dust content based on the first dust content and / or the second dust content and / or the third dust content.

[0138] It is understandable that the dust content on the surface of the evaporator 502 is generally positively correlated with the airflow of the blower 506 and the concentration of PM2.5 in the air. Therefore, by setting a priori correspondence between the airflow of the blower 506 and / or the PM2.5 concentration and the first dust content, the first dust content can be determined. Optionally, the control module 501 can also determine the first dust content based on the airflow of the blower 506 and / or the PM2.5 concentration using machine learning or artificial intelligence.

[0139] It is also understandable that the vehicle's mileage is usually positively correlated with the dust content on the surface of the evaporator 502. Therefore, by setting the correspondence between the vehicle's mileage and the target dust content, the second dust content can be determined. Optionally, the control module 501 can also determine the second dust content based on the vehicle's mileage using machine learning or artificial intelligence.

[0140] It is also understandable that the cumulative operating time of compressor 505 is usually positively correlated with the dust content on the surface of evaporator 502. Therefore, by setting the correspondence between the cumulative operating time of compressor 505 and the target dust content, the third dust content can be determined. Optionally, control module 501 can also determine the third dust content based on the cumulative operating time of compressor 505 using machine learning or artificial intelligence.

[0141] Furthermore, the control module 501 can also determine the target dust content based on one or more of the first dust content, second dust content, or third dust content. For example, the maximum value among the first, second, and third dust contents can be used as the target dust content. If the first, second, or third dust contents are not calculated, they are recorded as 0. For example, the target dust content can also be determined by a weighted average method, for example, with the first dust content having a weight of 30%, the second dust content having a weight of 30%, and the third dust content having a weight of 40%, thereby calculating the target dust content.

[0142] After the control module 501 determines the target dust content, it further controls the compressor 505 to operate at the target speed and target temperature if the target dust content exceeds a first threshold. Specifically, the compressor 505 compresses the gas at the target speed and / or target temperature, ensuring that impurities condense on the surface of the evaporator 502 after the compressed gas enters the evaporator 502. Exemplarily, it is understood that different compressors and evaporators have different performance characteristics, resulting in different target speeds and temperatures. For example, the target speed might be 1500 rpm or 2000 rpm, and the target temperature might be 10°C or 15°C. The duration for which the compressor 505 compresses the gas at the target speed and / or target temperature is not limited in this application; for example, it could be 1 minute, 2 minutes, or 3 minutes. The goal is to ensure that impurities condense on the surface of the evaporator 502.

[0143] Optionally, the first threshold mentioned above is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not limit this.

[0144] To remove impurities from the surface of evaporator 502, after the impurities have condensed on the surface of evaporator 502, the compressor can be stopped, and a hot airflow can be generated using blower 506 and heating module 504 to dry and remove dust from the surface of evaporator 502. For details on how control module 501 controls blower 506 and heating module 504 to carry away the condensed impurities from the surface of evaporator 502 using the generated hot airflow, please refer to the above. Figure 6 and Figure 7 The airflow direction diagram shown will not be elaborated upon here.

[0145] In another possible implementation, the control module 501 acquires the target amount of condensate on the surface of the evaporator 502.

[0146] For example, the control module 501 is used to acquire one or more of the following information: humidity of the evaporator 502 surface, temperature of the evaporator 502 surface, and dew point temperature. The control module 501 is used to determine the target amount of condensate on the evaporator 502 surface based on one or more of the above information.

[0147] Dew point temperature refers to the temperature at which water vapor in the air reaches saturation under certain air pressure and water vapor content. When the air temperature drops to the dew point temperature, the water vapor in the air will begin to condense into liquid water or ice crystals. Dew point temperature can be determined by methods such as the cold mirror method, capacitance method, and electrolysis method.

[0148] After determining the humidity, temperature, and dew point temperature of the evaporator 502 surface, the control module 501 can also determine the target condensate volume based on the correspondence table. The correspondence table shows the relationship between one or more of the humidity, temperature, and dew point temperature of the evaporator 502 surface and the target condensate volume on the evaporator 502 surface.

[0149] In addition, the control module 501 can also determine the target condensate volume through machine learning or artificial intelligence. After determining the target condensate volume on the surface of the evaporator 502, the control module 501 is also used to control the heating module 504 to generate heat to generate a hot airflow when the target condensate volume is greater than a second threshold, thereby drying the moisture on the surface of the evaporator 502.

[0150] Optionally, the second threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not limit this.

[0151] Of course, while controlling the heating module 504 to generate heat, the control module 501 also controls the blower 506 to blow air, so that the hot airflow can dry the moisture on the surface of the evaporator 502. For example, the control module 501 is used to control the blower 506 to blow air in the direction from the heat-conducting module to the evaporator when the target dust content on the surface of the evaporator 502 is greater than a first threshold and / or the target condensation on the surface of the evaporator 502 is greater than a second threshold. For details, please refer to the foregoing. Figure 6 and Figure 7 The airflow direction diagram shown will not be elaborated upon here.

[0152] Understandably, when the surface of evaporator 502 is in a humid and dusty environment for a long time, a large number of viruses and bacteria will grow on the surface of evaporator 502, which will endanger the health of passengers.

[0153] In one possible implementation, when the target dust content on the surface of the evaporator 502 is greater than a first threshold and / or the number of blowers 506 blowing air along the direction from the heat conduction module 503 to the evaporator 502 is greater than a third threshold, the control module 501 controls the activation of the disinfection and sterilization function on the surface of the evaporator 502, thereby achieving the purpose of regular deep cleaning to minimize the harm of bacteria to the human body.

[0154] The implementation details regarding the target dust content on the surface of evaporator 502 being greater than the first threshold can be found in the above description and will not be repeated here.

[0155] The situation where the blower 506 blows air more than the third threshold along the direction from the heat-conducting module 503 to the evaporator 502 includes cases where the target dust content on the surface of the evaporator 502 is greater than the first threshold and the target condensation on the surface of the evaporator 502 is greater than the second threshold. Taking a third threshold of 4 times as an example, and after the previous disinfection and sterilization, the target dust content on the surface of the evaporator 502 is greater than the first threshold twice, so the blower 506 blows air twice along the direction from the heat-conducting module 503 to the evaporator 502 for dust removal. The target condensation on the surface of the evaporator 502 is greater than the second threshold three times, so the blower 506 blows air three times along the direction from the heat-conducting module 503 to the evaporator 502 for dust removal. This is equivalent to the blower 506 blowing air 2+3=5 times along the direction from the heat-conducting module 503 to the evaporator 502 after the previous disinfection and sterilization. Since 5 times is greater than the third threshold, the control module 501 activates the disinfection and sterilization function on the surface of the evaporator 502.

[0156] Optionally, the aforementioned third threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0157] For example, the control module 501 can disinfect and sterilize the surface of the evaporator 502 by controlling the ultraviolet lamp 507 to emit ultraviolet light.

[0158] For example, the control module 501 can also control the negative ion generator 508 to generate negative air ions and control the blower to blow air negative ions onto the surface of the evaporator 502, thereby disinfecting and sterilizing the surface of the evaporator 502. It is understood that the control module 501 can simultaneously control the heating module 504, the negative ion generator 508, and the blower 506 to achieve simultaneous dust removal and sterilization, or simultaneous condensate removal and sterilization.

[0159] Understandably, the above method involves the control module 501 automatically cleaning the evaporator 502 by acquiring the target dust content and / or target condensate content. This effectively reduces dust accumulation or condensate content on the surface of the evaporator 502, ensuring that the evaporator 502 can perform its normal working function and thus ensuring the normal operation of the vehicle's air conditioning system. Furthermore, the control module 501, by automatically controlling the ultraviolet lamp 507 and / or the negative ion generator 508, can also achieve the effect of periodically deep cleaning the surface of the evaporator 502 to remove viruses and bacteria, thereby minimizing the harm of bacteria to the human body.

[0160] Furthermore, the self-cleaning device 500 provided in this application can also be controlled by a first button to perform corresponding cleaning operations. The description of the first button can be found above. Figure 9 The relevant descriptions will not be repeated here.

[0161] Please see Figure 10 Users can control the self-cleaning device 500 to perform self-cleaning operations by manipulating the first button. For example, pressing the first button will remove dust from the surface of the evaporator 502. Repeatedly pressing the first button will dry the surface of the evaporator 502. Rotating the first button will disinfect the surface of the evaporator 502. For details on how the self-cleaning device 500 performs these dust removal, drying, or disinfection operations, please refer to the above. Figure 9 The relevant descriptions will not be repeated here.

[0162] In summary, the self-cleaning device provided in this application can automatically clean the surface of the evaporator without adding any additional devices / air ducts. It can achieve a highly automated self-cleaning function without increasing the cost of the vehicle air conditioner and provide users with a better user experience.

[0165] Optionally, the mobile terminal can be a vehicle, drone, robot, or other intelligent terminal or transportation tool; alternatively, the mobile terminal can also be industrial equipment. It should be understood that the mobile terminal involved in this application can include vehicles, robots, drones, ships, vessels, and other intelligent terminals or transportation tools. Here, "vehicle" is a broad concept and can refer to transportation tools (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), etc. For example, a robot can be an automated guided vehicle (AGV), a walking conversational robot, a service robot, etc. Industrial equipment includes industrial robots, robotic arms, etc.
