[0056] Figure 1 This is a connection block diagram of an air conditioning water tank cleaning system 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of an air conditioning water tank cleaning system 100 in an air conditioner 200 according to an embodiment of the present invention. Figure 1 As shown, in one embodiment, the air conditioner water tank cleaning system 100 includes a water level sensor 10, a light sensor 20, a cleaning fluid dispensing device 30, and a roller 40. The water level sensor 10 is used to detect the water level in the water tank 201 of the air conditioner 200, such as... Figure 2 As shown, in one embodiment, the water level sensor 10 can be set at a preset height in the water tank 201 to detect whether the water level in the water tank 201 is higher than a first preset value. In other embodiments, the water level sensor 10 can also be a sensor with a certain range that can measure the water level within a certain height range. The light sensor 20 is used to detect the light signal after the light source passes through the water tank 201 and convert it into a corresponding electrical signal value, thereby obtaining the dirt information of the water in the water tank 201. The light sensor 20 can be set at the bottom of the water tank 201. In other embodiments, it can be located at any position that can effectively receive the light signal from the light source. The light source here can be a specific laser light source or natural light, as long as it can pass through the water in the water tank 201 and be incident on the light sensor 20. The light sensor 20 is generally provided with a detection element that senses the light signal, and the light shines on the photosensitive surface 21 of the detection element. The cleaning fluid dispensing device 30 is signal connected to both the water level sensor 10 and the light sensor 20, and is used to dispense scale cleaning fluid into the water tank 201 when the water level in the water tank 201 is lower than the first preset value and the electrical signal value is higher than the second preset value. like Figure 2As shown, the air conditioner is generally provided with a cleaning liquid containing box 202 for containing the scale cleaning liquid, and the cleaning liquid feeding device 30 is used to spray the scale cleaning liquid in the cleaning liquid containing box 202 into the water tank 201, and the cleaning liquid feeding device 30 can use a common liquid driving device such as a water pump to deliver the liquid. The roller 40 is arranged in the water tank 201 and is used to start working after the cleaning liquid feeding device 30 feeds the scale cleaning liquid until the electric signal value is lower than or equal to the second preset value. The roller 40 generally includes a plurality of rotatable washing trays, and the rotation of the washing trays can make the scale cleaning liquid fully mix with the water in the water tank 201, so as to effectively remove the dirt and impurities in the water in the water tank 201.

[0057] The air conditioner water tank cleaning system 100 of the embodiment includes a water level sensor 10 and a light sensor 20, which can respectively detect the water level in the water tank 201 of the air conditioner 200 and a light signal reflecting the dirt degree of the water, and the light sensor 20 is also used to convert the light signal into a corresponding electric signal value. Generally, the larger the electric signal value, the more serious the dirt degree of the water. The cleaning liquid feeding device 30 feeds the scale cleaning liquid to the water tank 201 when the water level in the water tank 201 is lower than the first preset value and the electric signal value is higher than the second preset value, and starts the roller 40 in the water tank 201 to start purifying the water in the water tank 201. In the above process, the dirt degree of the water in the water tank 201 can be known in time through the detection of the light sensor 20, and the water is purified in time when the water quality is not up to standard. Through the setting of the water level sensor 10, the total amount of the water in the water tank 201 can be obtained, and the purification is started only when the water level is lower than the first preset value, which can avoid affecting the detection accuracy of the light sensor 20 due to the excessive total amount of the dirt and the excessive total amount of the water.

[0058] In one embodiment, the cleaning liquid feeding device 30 is also used to determine the feeding amount of the scale cleaning liquid according to the size of the electric signal value. Since the electric signal value reflects the dirt degree of the water, the feeding amount of the scale cleaning liquid determined according to the size of the electric signal value can make the feeding amount more accurate. Here, the feeding amount of the scale cleaning liquid can be controlled by a hydraulic device.

[0059] In the embodiment, the feeding amount of the scale cleaning liquid is determined according to the size of the electric signal value, so that the feeding amount of the scale cleaning liquid matches the dirt degree of the water in the water tank 201, and the feeding amount of the scale cleaning liquid is more accurate, which avoids the problems of waste or incomplete purification caused by excessive or insufficient feeding amount.

[0060] Figure 3 is a connection block diagram of the air conditioner water tank cleaning system 100 according to another embodiment of the present application. As shown in Figure 3As shown, in another embodiment, the air conditioning water tank cleaning system 100 further includes a fan 50 for introducing airflow into the water tank 201. The fan 50 is shut off after the cleaning liquid dispensing device 30 dispenses scale cleaning liquid. Generally, the air conditioner also includes a fan 50 for drawing air from the air inlet through the water tank 201 to the air outlet. Air typically flows in and out radially from the roller 40 inside the water tank 201. Solid pollutants such as particulate matter and lint in the airflow, as well as water-soluble harmful gases such as formaldehyde and benzene, are soluble in water. Simultaneously, the airflow can carry away some moisture, thus achieving water washing purification and / or humidification.

[0061] In this embodiment, the blower 50 is turned off when cleaning scale from the water tank 201 to prevent dirty airflow from flowing out and polluting the environment.

[0062] like Figure 3 As shown, in one embodiment, the air conditioning water tank cleaning system 100 further includes an interaction module 60, which is signal-connected to the cleaning fluid dispensing device 30. The interaction module 60 is used to acquire user instructions and, upon receiving an activation instruction to instruct the user to start the descaling process, sends it to the cleaning fluid dispensing device 30, so that the cleaning fluid dispensing device 30 dispenses descaling fluid upon receiving the activation instruction. The interaction module 60 is also signal-connected to the light sensor 20, and is used to issue a reminder signal indicating that the descaling process is complete when the electrical signal value is lower than or equal to a second preset value.

[0063] The interaction module 60 may include a voice interaction device for recognizing user voice commands and issuing voice prompts. The interaction module 60 may also include a display screen or other display device to receive user commands when the user operates the display interface or buttons, and then display the cleaning status on the display device, such as "starting cleaning," "cleaning in progress," or "cleaning complete."

[0064] The air conditioning water tank cleaning system 100 in this embodiment is also equipped with an interactive module 60, which can improve the interactivity with users. The cleaning can start only after the user confirms, and the user can also be informed whether the cleaning is completed, thereby improving the user experience and satisfaction.

[0065] like Figure 3 As shown, in a further embodiment, the air conditioning water tank cleaning system 100 also includes a solenoid valve 70, disposed at the water outlet 203 of the water tank 201, for controlling the opening and closing of the water outlet 203. In one embodiment, the drum 40 is used to periodically rotate at a preset speed until the scale cleaning liquid is dispensed from the cleaning liquid dispensing device 30 until the electrical signal value is lower than or equal to a second preset value, and the solenoid valve 70 is used to periodically open after the drum 40 stops rotating.

[0066] During the process described above, the drum 40 rotates periodically. After each cycle, the electrical signal value is checked to see if it is lower than or equal to a second preset value. If it is, the cleaning is complete; otherwise, the next cycle begins. During the periodic rotation of the drum 40, the fan 50 can remain off, or it can periodically shut off along with the drum 40, meaning it opens when the drum 40 rotates and opens when it stops. The solenoid valve 70 opens after each rotation of the drum 40, draining the water from the water tank 201 for the current cycle. Of course, the water tank 201 is replenished with water through a water inlet device after each cleaning cycle.

[0067] In this embodiment, the roller 40 is rotated periodically, which divides the scale removal into multiple cycles. The duration of each cleaning is controlled, and the water in the water tank 201 is checked after each cleaning to see if it meets the standard. If it does, the next cleaning cycle will not be performed. This allows the cleaning time to match the degree of dirtiness of the water as closely as possible.

[0068] Figure 4 This is a schematic diagram of the refractive element 80 of an air conditioning water tank cleaning system 100 according to an embodiment of the present invention. Figure 4 As shown, in one embodiment, the air conditioning water tank cleaning system 100 further includes a refractive element 80 disposed at the water tank 201. The refractive element 80 contains a medium with adjustable concentration, used to change the illumination path of the light source so that the light from the light source entering the water tank 201 is perpendicular to the photosensitive surface 21 of the light sensor 20. For example, the refractive element 80 includes a transparent shell filled with liquid. The concentration of the liquid can be changed; for example, the liquid is a mixture of water and glucose. By changing the amount of glucose placed in the shell, the concentration of the liquid can be changed, thereby changing the angle of the light from the light source. Of course, the shell can also be designed to allow for the replacement of the liquid inside. After calculating the required target concentration of liquid, the target concentration of liquid is filled into the shell. When a different concentration of liquid is needed, the current liquid is drained and then a new concentration of liquid is filled in.

[0069] In this embodiment, by setting a refractive element 80 at the water tank 201 that can change the illumination path of the light source, it is possible to control the light after the light source enters the water tank 201 to be perpendicular to the photosensitive surface 21 of the light sensor 20, so that the light sensor 20 can acquire more light signals, thereby improving the efficiency and accuracy of detection.

[0070] Figure 5 This is a schematic diagram showing the connection between the refractive element 80 and the water tank 201 in an air conditioning water tank cleaning system 100 according to an embodiment of the present invention. In one embodiment, the refractive element 80 is movably disposed at the water tank 201. In a specific embodiment, such as... Figure 5As shown, a groove 204 is arranged on the side of the water tank 201, and the refractive element 80 is slidably arranged in the groove 204, for example, in the up-down direction. Of course, the groove 204 of the water tank 201 also needs to be transparent, so that the light can be effectively arranged, the light sensor 20 can receive the light signal, and the user can observe the water level and water quality in the water tank 201.

[0071] In this embodiment, the refractive element 80 is arranged to be movable relative to the water tank 201, so that light at different positions can be guided to the light sensor 20, and the scale situation at multiple positions in the water tank 201 can be reflected, so that the data of the light sensor 20 is more representative, that is, the accuracy of the detected dirt degree of the water is improved, and the subsequent cleaning process is more accurate and reasonable.

[0072] Figure 6 is a flowchart of a control method of the air conditioner water tank cleaning system 100 according to an embodiment of the present application. The present application also provides a control method of the air conditioner water tank cleaning system 100 in any of the above embodiments or combinations of embodiments, such as Figure 6 As shown, in one embodiment, the control method comprises:

[0073] Step S100, detecting the water level of the water tank 201.

[0074] That is, the water level of the water tank 201 is detected by the water level sensor 10.

[0075] Step S200, detecting the light signal after the light source passes through the water tank 201 and converting it into a believed electrical signal value.

[0076] Step S100 and step S200 can be performed simultaneously or sequentially, without regard to the order.

[0077] Here, the light signal can be detected by the light sensor 20, and the light source can be sunlight or a specific laser, etc. After the light source irradiates the water in the water tank 201, different light signals will be obtained due to different dirt degrees in the water.

[0078] Step S300, when the water level of the water tank 201 is lower than the first preset value and the electrical signal value is higher than the second preset value, the scale cleaning liquid is thrown into the water tank 201.

[0079] Here, the throwing of the scale cleaning liquid can be performed by controlling the cleaning liquid throwing device 30. For example, the throwing of the scale cleaning liquid can be controlled by a combination of a water pump and a flow valve.

[0080] Step S400, after the cleaning liquid throwing device 30 throws the scale cleaning liquid, the roller 40 is controlled to start working until the electrical signal value is lower than or equal to the second preset value.

[0081] Step S400 can be realized by limiting time, for example, the control cylinder 40 starts to work after a certain time of starting the cleaning liquid dispensing device 30, or by recognizing whether the cleaning liquid dispensing device 30 is closed to control whether the cylinder 40 starts to work. The work of the cylinder 40 is that the cylinder 40 starts to rotate.

[0082] The control passing of the embodiment can know the dirt degree of the water in the water tank 201 in time through detecting the light signal of the light source passing through the water tank 201, and purify in time when the water quality is not up to standard. The total amount of the water in the water tank 201 can be obtained through detecting the water level in the water tank 201, and the water is purified only when the water level is lower than the first preset value, which can avoid affecting the detection accuracy of the light sensor 20 due to the total amount of the water being too large.

[0083] Figure 7 is a flow chart of a control method for the air conditioner water tank cleaning system 100 according to another embodiment of the present application. In another embodiment, as shown in Figure 7 , step S300 includes:

[0084] Step S250, judge whether the water level of the water tank 201 is lower than the first preset value and whether the electric signal value is higher than the second preset value, if yes, enter step S310, otherwise return to step S100.

[0085] Step S300 includes:

[0086] Step S310, determine the dispensing amount of the water scale cleaning liquid according to the size of the electric signal value.

[0087] Step S320, obtain the instruction of the user.

[0088] Step S330, judge whether the start instruction for indicating starting the water scale cleaning is received, if yes, enter step S340, otherwise return to step S320.

[0089] Step S340, dispense the water scale cleaning liquid according to the dispensing amount determined according to the electric signal value.

[0090] Step S400 includes:

[0091] Step S410, control the cylinder 40 to rotate at a preset rotating speed, and control the fan 50 to stop.

[0092] Step S420, start timing.

[0093] Step S430, judge whether the time reaches the preset time, if yes, enter step S440, otherwise continue timing.

[0094] Step S440, control the drum 40 to stop rotating and control the electromagnetic valve 70 to open after the drum 40 stops rotating.

[0095] Step S450, detect the light signal of the light source after passing through the water tank 201 and convert it into a corresponding electrical signal value.

[0096] Step S460, determine whether the electrical signal value is lower than or equal to the second preset value, if yes, go to step S500, otherwise return to step S410 to continue the next cycle of cleaning.

[0097] Step S500, prompt the user to complete the cleaning. This can be achieved through the above-mentioned interactive module 60.

[0098] The control method of the embodiment closes the fan 50 when performing the scale cleaning of the water in the water tank 201, avoids the dirty airflow from flowing out and polluting the environment, can improve the interactivity with the user through the interaction with the user, starts the cleaning after the user confirms, can also inform the user whether the cleaning is completed, thereby improving the user experience and satisfaction. And periodically rotating the drum 40, i.e. dividing the scale cleaning into multiple cycles, controlling the length of each cleaning, detecting whether the water in the water tank 201 meets the standard after each cleaning, and not performing the next cycle of cleaning when it meets the standard, which can make the cleaning time match the dirtiness of the water as much as possible.

[0099] Of course, after the air conditioner water tank cleaning system 100 is provided with a movable refractive element 80, the control method needs to adjust the medium concentration in the refractive element 80 when detecting the light signal of the light source through the light sensor 20, and control the refractive element 80 to slide to multiple positions to collect the light signal, and then obtain the corresponding electrical signal value through a certain algorithm, such as taking the average of the electrical signal values at each position.

[0100] The application also provides an air conditioner, as shown in the figure, which comprises the air conditioner water tank cleaning system 100 in any of the above embodiments. Figure 2

It is used to dispense scale cleaning fluid into the water tank when the water level in the tank is lower than a first preset value and the electrical signal value is higher than a second preset value, so as to avoid the total amount of dirt from being too large due to excessive water, which would affect the detection accuracy of the light sensor. A roller, disposed inside the water tank, is activated after the scale cleaning solution is dispensed from the cleaning solution dispensing device until the electrical signal value is lower than or equal to the second preset value. The cleaning fluid dispensing device is also used to determine the amount of scale cleaning fluid to be dispensed based on the magnitude of the electrical signal value. The air conditioning water tank cleaning system also includes: A blower is used to introduce airflow into the water tank, and the blower is turned off after the scale cleaning solution is added by the cleaning solution dispensing device. A refractive element is disposed in the water tank. The refractive element contains a medium with adjustable concentration to change the illumination path of the light source so that the light from the light source after entering the water tank is perpendicular to the photosensitive surface of the light sensor. The refractive element is movably disposed at the water tank, and can guide light from different positions to the light sensor, thereby reflecting the scale condition at multiple locations within the water tank.

2. The air conditioning water tank cleaning system according to claim 1, characterized in that, Also includes: An interactive module is connected to the cleaning fluid dispensing device. The interactive module is used to obtain user instructions and send them to the cleaning fluid dispensing device after obtaining an instruction to start the scale cleaning process, so that the cleaning fluid dispensing device dispenses the scale cleaning fluid after receiving the instruction. The interactive module is also connected to the light sensor signal and is used to issue a reminder signal indicating that the scale cleaning is complete when the electrical signal value is lower than or equal to the second preset value.
