Description

Technical Field

The method comprises: S1, controlling the air conditioner to enter a sterilization mode via a mobile terminal associated with the air conditioner; S2, operating the sterilization mode and displaying the sterilization progress on the mobile terminal. The technical solution provided by the present invention solves the problem of users being unable to specifically and intuitively understand the heat exchanger sterilization process and bacterial concentration, making it easier for users to confirm the heat exchanger's sterilization status at any time. Background Art

[0002] The cleanliness and health of home environments are increasingly valued by users. Air conditioners, a common device for regulating indoor air parameters, significantly impact these conditions. Over time, the indoor heat exchanger in an air conditioner inevitably becomes dirty, leading to bacterial growth. High bacterial concentrations on the heat exchanger surface can negatively impact the user's health if not promptly sterilized. While some existing air conditioners offer sterilization and display functions, these systems offer limited visibility into the actual sterilization process, and users are unable to readily confirm the bacterial concentration in the heat exchanger.

[0003] The technical solutions most similar to the present invention are CN114484765A and CN111397149A. Although these original solutions can display the sterilization status or process, they have the defect that the display method is not specific and intuitive enough. Summary of the Invention

[0069] Although some air conditioners have sterilization and corresponding display functions, they cannot enable users to understand the actual status of the heat exchanger sterilization process in a specific and intuitive way, and users cannot confirm the bacteria concentration of the heat exchanger at any time. In order to solve this problem, the present invention proposes a sterilization control and display method for air conditioner heat exchanger, such as Figure 1 As shown, this method is achieved by controlling the air conditioner to enter the sterilization mode through a mobile terminal bound to the air conditioner, and then running the sterilization mode, and displaying the sterilization process through the mobile terminal. Preferably, this display is a dynamic display, so that the user can more intuitively understand the sterilization process of the heat exchanger. The sterilization process displayed by this method includes sterilization parameters and sterilization modes. The sterilization parameters include the bacterial contamination level. The bacterial contamination level is displayed on the operation interface of the mobile terminal. Different bacterial contamination levels have different interface colors. There are multiple sterilization modes, and the sterilization processes of different sterilization modes have different animation effects. Displaying the sterilization process through the mobile terminal includes having different displays for different sterilization modes and / or different displays for different sterilization parameters on the operation interface of the mobile terminal. This ensures that the user can intuitively and clearly understand the actual situation of sterilization and confirm the bacterial concentration of the heat exchanger.

[0070] To further illustrate the technical solution of the present invention, Figures 1 to 7 , the following specific embodiments are provided.

[0071] Example 1

[0072] According to one or more embodiments of the present invention, an embodiment of the present invention provides a method for controlling and displaying sterilization of an air conditioner heat exchanger, such as Figure 2 As shown, the air conditioner heat exchanger sterilization control and display method of the embodiment of the present invention includes at least the following four steps S1, S2, S3, and S4:

[0073] S1, receive sterilization instructions.

[0074] S2, detects the bacterial concentration on the surface of the air conditioner heat exchanger, determines the corresponding bacterial contamination level according to the bacterial concentration and initializes the sterilization interface.

[0075] S3, according to the sterilization instruction, the high-temperature sterilization mode and the low-temperature sterilization mode are run successively, and the sterilization process is visualized through the interface of the mobile terminal.

[0076] S4, re-detect the bacterial concentration on the surface of the air conditioner heat exchanger and update the bacterial contamination level and interface after sterilization.

[0077] in,

[0078] Step S1, receiving a sterilization instruction.

[0079] The air conditioner needs to start the sterilization command through the command issued by the mobile terminal. First, it needs to bind the mobile terminal. Then it can receive the sterilization command issued by the mobile terminal.

[0080] like Figure 3 As shown, a connection is established between the mobile terminal and the air conditioner, and the binding can be performed through wireless communication methods such as WIFI and Bluetooth. The mobile terminal can be a smart mobile device such as a smart phone or a tablet computer.

[0081] By binding the mobile terminal, the air conditioner establishes communication with the mobile terminal and can receive the sterilization instruction issued by the mobile terminal. The content of this instruction is to sterilize the surface of the air conditioner heat exchanger.

[0082] Step S2: Detect the bacterial concentration on the surface of the air conditioner heat exchanger, determine the corresponding bacterial contamination level according to the bacterial concentration, and initialize the sterilization interface.

[0083] After the air conditioner receives the instruction from the mobile terminal to sterilize the heat exchanger surface,

[0084] First, the colony size on the surface of the air conditioner heat exchanger was tested to determine the bacterial concentration.

[0085] The size of the colonies on the surface of the air-conditioning heat exchanger is detected by an image sensor to determine the bacterial concentration. That is, the surface of the air-conditioning heat exchanger is photographed by a camera, and the colonies are segmented using a U-Net target segmentation neural network model. Then, the area of ​​each colony area is calculated, and the total area of ​​all colony areas is counted as the bacterial concentration.

[0086] Then, the corresponding bacterial contamination level and the color of the interface are determined from a bacterial contamination level table according to the bacterial concentration.

[0087] The bacterial contamination level table is composed of three types of data: bacterial concentration, bacterial contamination level, and interface color. The bacterial concentration indicates the number of bacteria on the surface of the air-conditioning heat exchanger. The bacterial contamination level indicates the degree of bacterial contamination on the heat exchanger surface, which is obtained through the bacterial concentration. The interface color is the color information of the sterilization interface displayed on the air-conditioning control-related App software of the mobile terminal.

[0088] In the bacterial contamination level table, the corresponding relationships among the above three are as follows:

[0089] When the bacterial concentration is less than or equal to the first preset value, the bacterial contamination level is determined to be "no contamination" and the interface color is the first color;

[0090] When the bacterial concentration is greater than the first preset value and less than or equal to the second preset value, the bacterial contamination level is determined to be "lightly contaminated" and the interface color is the second color;

[0091] When the bacterial concentration is greater than the second preset value and less than or equal to the third preset value, the bacterial contamination level is determined to be "moderate contamination" and the interface color is the third color;

[0092] When the bacterial concentration is greater than the third preset value, the bacterial contamination level is determined to be "heavy contamination" and the interface color is the fourth color;

[0093] The first preset value is less than the second preset value and is less than the third preset value, and the first color, the second color, the third color and the fourth color are all different.

[0094] Preferably, the first preset value is 100 pixels, and the first color is green; the second preset value is 500 pixels, and the second color is gray; the third preset value is 1000, and the third color is yellow; and the fourth color is red.

[0095] Step S3: According to the sterilization instruction, the high-temperature sterilization mode and the low-temperature sterilization mode are run in sequence, and the sterilization process is visualized through the interface of the mobile terminal.

[0096] According to the sterilization instruction, run the high temperature sterilization mode first and then the low temperature sterilization mode.

[0097] First, the high-temperature sterilization mode is run for sterilization, and the sterilization process is visualized through the mobile terminal.

[0098] The air conditioner adjusts the refrigerant flow direction within the system to align with the refrigerant flow direction in heating mode, so that the high-temperature refrigerant discharged from the compressor flows through the indoor heat exchanger first. This heat is then used to heat the indoor heat exchanger, raising the surface temperature of the indoor heat exchanger to above a first temperature threshold for high-temperature sterilization. Preferably, the first temperature threshold is 60 degrees Celsius.

[0099] The mobile terminal visualizes the high-temperature sterilization process. Specifically, the size of the bacterial pattern segmented in the image is proportional to the bacterial concentration on the heat exchanger surface and inversely proportional to the duration of the high-temperature sterilization mode. Specifically, as the duration of the high-temperature sterilization mode increases, the bacterial pattern shrinks.

[0100] timing the duration of the high-temperature sterilization mode operation, and determining whether the operation time of the high-temperature sterilization mode is greater than a first duration threshold; if not, continuing to operate the high-temperature sterilization mode;

[0101] If yes, the low temperature sterilization mode is run for sterilization, and the sterilization process is visualized through the mobile terminal. Preferably, the first time threshold is 15 minutes.

[0102] Second, after the high-temperature sterilization mode expires, the low-temperature sterilization mode is run, and the sterilization process is visualized through the mobile terminal.

[0103] Adjust the refrigerant flow direction within the system to align with the refrigerant flow direction in cooling mode, so that the high-temperature refrigerant discharged from the compressor first flows through the outdoor heat exchanger, and the low-temperature refrigerant, after throttling and reducing the pressure, is then input into the indoor heat exchanger. The low-temperature refrigerant's "cold capacity" absorbs heat from the indoor heat exchanger, reducing the surface temperature of the indoor heat exchanger to below a second temperature threshold for rapid cooling and sterilization. Preferably, the second temperature threshold is 5 degrees Celsius.

[0104] The low-temperature sterilization process is visually displayed on the mobile terminal. Specifically, the size of the bacterial pattern is proportional to the bacterial concentration on the heat exchanger surface and inversely proportional to the duration of the low-temperature sterilization mode. Specifically, as the air conditioner continues to operate in the low-temperature sterilization mode for an increasing period of time, the bacterial pattern shrinks.

[0105] timing the duration of the low-temperature sterilization mode operation, and determining whether the low-temperature sterilization mode operation time is greater than a second duration threshold; if not, continuing to operate the low-temperature sterilization mode;

[0106] If so, exit the low-temperature sterilization mode. Preferably, the second time threshold is 15 minutes.

[0107] After exiting the sterilization mode, the bacterial concentration of the heat exchanger is re-detected, and the bacterial contamination level and the interface color after the sterilization are completed are displayed on the interface.

[0108] Step S4: Detect the bacterial concentration on the surface of the air conditioner heat exchanger again, and update the bacterial contamination level and interface after sterilization.

[0109] After exiting the sterilization mode, the bacterial concentration on the surface of the heat exchanger is detected again, and the results of the sterilization operation are displayed visually. If the sterilization is successful and the effect is good, the bacterial contamination level is "no contamination" and the interface color is green.

[0110] Example 2

[0111] According to one or more embodiments of the present invention, an embodiment of the present invention provides an air conditioner heat exchanger sterilization control and display device, which includes a collector, a memory, a processor and a display. The collector is used to collect the colony size of the air conditioner heat exchanger. The memory is used to store the data collected by the collector and the intermediate data and results generated during the processor operation. The processor is used for sterilization control calculations and calculation of colony concentration and visualization data of the sterilization process. The display is used to visualize the sterilization process. Figure 4 As shown, the functions implemented by the embodiment of this device specifically include the following steps:

[0112] S301: A sterilization command is input and sent to the air conditioner via the user interface of a mobile terminal connected to the air conditioner. This sterilization command controls the air conditioner to operate in a high-temperature sterilization mode and a low-temperature sterilization mode. High-temperature sterilization uses higher temperatures to kill bacteria, while low-temperature sterilization uses abrupt temperature changes from high to low to kill bacteria.

[0113] S302: The air conditioner detects the bacterial concentration on the surface of the heat exchanger using a detection device specifically used to detect the bacterial concentration on the surface of an object.

[0114] S303: Determine the corresponding bacterial contamination level and interface color according to the bacterial concentration.

[0115] When the bacterial concentration is less than or equal to the first preset value, the bacterial contamination level is determined to be "no contamination" and the interface color is the first color;

[0116] When the bacterial concentration is greater than the first preset value and less than or equal to the second preset value, the bacterial contamination level is determined to be "lightly contaminated" and the interface color is the second color;

[0117] When the bacterial concentration is greater than the second preset value and less than or equal to the third preset value, the bacterial contamination level is determined to be "moderate contamination" and the interface color is the third color;

[0118] When the bacterial concentration is greater than the third preset value, the bacterial contamination level is determined to be "heavy contamination" and the interface color is the fourth color;

[0119] The first preset value is less than the second preset value and is less than the third preset value, and the first color, the second color, the third color and the fourth color are all different.

[0120] S304: Display the bacterial contamination level and interface color on the operation interface. Figure 3 As shown in the mobile terminal's operation interface, the text displayed in the circle is the bacterial contamination level, and the color filled in the circle is the interface color. This simultaneous display of the bacterial contamination level and the interface color presents the heat exchanger's bacterial concentration in a more detailed and intuitive way.

[0121] S305: The air conditioner is controlled to operate in a high-temperature sterilization mode according to the sterilization instruction, and a high-temperature sterilization mode animation is displayed within a box on the operation interface. The air conditioner is controlled to operate in a high-temperature sterilization mode by adjusting the refrigerant flow direction within the system to align with the refrigerant flow direction in heating mode. This allows the high-temperature refrigerant discharged from the compressor to flow through the indoor heat exchanger first. This heat is then used to heat the indoor heat exchanger, raising the surface temperature of the indoor heat exchanger to above 60°C for high-temperature sterilization. Figure 5 Schematic diagram of the high temperature sterilization animation of the air conditioner of the present invention, as shown in FIG. Figure 5 As shown, the high-temperature sterilization animation includes a heat exchanger 210, bacteria 220 and a high-temperature pattern 230. The size of the bacterial pattern is proportional to the bacterial concentration on the surface of the heat exchanger, that is, inversely proportional to the length of time the air conditioner runs in the high-temperature sterilization mode. That is, as the length of time the air conditioner runs in the high-temperature sterilization mode continues to increase, the bacterial pattern will continue to shrink.

[0122] S306: Determine whether the air conditioner has been operating in the high-temperature sterilization mode for a period greater than a first time threshold. If so, step S307 is executed to control the air conditioner to operate in the low-temperature sterilization mode. Specifically, when the air conditioner has been operating in the high-temperature sterilization mode for a period greater than the first time threshold, the air conditioner is controlled to switch from the high-temperature sterilization mode to the low-temperature sterilization mode.

[0123] S307: The air conditioner is controlled to operate in a low-temperature sterilization mode according to the sterilization instruction, and a low-temperature sterilization mode animation is displayed in a box on the operation interface. The air conditioner is controlled to operate in a low-temperature sterilization mode by adjusting the refrigerant flow direction within the system to align with the refrigerant flow direction in the cooling mode. This causes the high-temperature refrigerant discharged from the compressor to flow through the outdoor heat exchanger first, and the low-temperature refrigerant, which has been throttled and reduced in pressure, is then input into the indoor heat exchanger. The low-temperature refrigerant's "coldness" absorbs heat from the indoor heat exchanger, reducing the surface temperature of the indoor heat exchanger to below 5°C for rapid cooling and sterilization. Figure 6 Schematic diagram of low-temperature sterilization animation of the air conditioner of the present invention, as shown in FIG. Figure 6 As shown, the low-temperature sterilization animation includes a heat exchanger 210, bacteria 220 and a low-temperature pattern 240. The size of the bacterial pattern is proportional to the bacterial concentration on the surface of the heat exchanger, that is, inversely proportional to the length of time the air conditioner runs in the low-temperature sterilization mode. That is, as the length of time the air conditioner runs in the low-temperature sterilization mode continues to increase, the bacterial pattern will continue to shrink.

[0124] S308: Determine whether the air conditioner has been operating in the low-temperature sterilization mode for a time period greater than a second time threshold. If so, execute step S309 to terminate the sterilization process. Specifically, if the air conditioner has been operating in the low-temperature sterilization mode for a time period greater than the second time threshold, the air conditioner is controlled to exit the sterilization mode.

[0125] S309: After confirming that the sterilization process is completed, the air conditioner exits the sterilization mode and can then operate in a normal cooling or heating mode.

[0126] S310: After the sterilization process is completed, the air conditioner automatically re-detects the bacterial concentration on the surface of the heat exchanger and displays the bacterial contamination level and interface color after the sterilization is completed on the operation interface.
