[0043] Example 1

[0044] An automatic dispensing device for a water treatment agent for a washing machine, the washing machine comprising a turbidity detection device 17 and an ultrasonic cleaning device 18, the turbidity detection device 17 being mounted at the bottom of an outer drum 16 of the washing machine, the ultrasonic cleaning device 18 being mounted on a side wall of the turbidity detection device 17, the ultrasonic cleaning device 18 being used to clean the surface of the turbidity detection device 17; the automatic dispensing device 11 comprising a water quality detection device 3 and a dispensing storage device 5, a water quality detection device 3 being arranged at the water inlet end of the washing machine to detect different parameters of washing water before entering the washing device, a controller distinguishing the water quality parameters by steps according to the different parameters of the water quality, storing parameters of different water quality dispensing agent dispensing ratios corresponding to the data step range in a cloud platform, and adjusting the dispensing agent input according to the water quality corresponding dispensing agent parameters of the cloud platform.

[0045] In this embodiment, the automatic delivery device 11 further includes a water inlet valve 1 and a delivery storage device 5 from the water inlet direction to the water outlet direction;

[0046] The automatic dispensing device 11 is provided with a dispensing pump 2, a water quality detection device 3, a detergent dispensing chamber 8, and a water quality treatment dispensing chamber 9 in sequence from the water inlet valve 1 to the dispensing storage device 5.

[0047] In this embodiment, the automatic dispensing device 11 is arranged on the upper part of the inner drum 15 of the washing machine. The automatic dispensing device 11 is installed between the left side wall 12 of the washing machine and the counterweight 13, and is connected to the front plate 14 of the washing machine. The automatic dispensing device 11 also includes a water channel upper cover 4 and a water channel lower cover 6 from top to bottom. A one-way water channel for the water treatment agent is set between the water channel upper cover 4 and the water channel lower cover 6 in the direction 5 from the dispensing pump 2 to the dispensing storage device. The automatic dispensing device 11 sets a one-way water channel for the water treatment agent from the direction of the dispensing storage device 5 by the self-dispensing pump 2, which can ensure that the water treatment agent flows in a preset direction, thereby simplifying the dispensing process of the water treatment agent, avoiding manual operation, and improving the convenience of operation.

[0048] In this embodiment, by controlling the delivery pump 2, the delivery amount of the water treatment agent can be accurately controlled to avoid excessive or insufficient delivery, thereby improving the water treatment effect. The delivery pump 2 and the one-way waterway are provided to avoid backflow of the water treatment agent, thereby ensuring that the delivered water treatment agent only flows in a certain direction, preventing the water treatment agent from backflowing or flowing back to the delivery and storage direction, thereby improving safety. By controlling the automatic delivery device 11, it can be ensured that the water treatment agent is delivered according to the preset dosage and direction, thereby improving the uniform distribution and effect of the water treatment agent and enhancing the effect of water treatment.

[0049] The washing machine also includes a turbidity detection device 17 and a controller.

[0050] The turbidity detection device 17 measures the turbidity of the washing water after the washing machine rinses the clothes.

[0051] The controller determines whether to re-execute the rinsing process based on the turbidity value of the washing water after rinsing the clothes.

[0052] In an embodiment, a turbidity detection device 17 is used to measure the turbidity of the washing water after rinsing in the washing machine. By measuring the turbidity of the clothes, the rinsing effect of the clothes is judged. If the turbidity is high, it means that there is still residual dirt. The controller re-executes the rinsing program to ensure that the clothes are thoroughly rinsed.

[0053] In this embodiment, through the cooperation of the turbidity detection device 17 and the controller, unnecessary rinsing procedures can be avoided. The rinsing procedure will be re-executed only when the turbidity exceeds a certain threshold, thereby reducing unnecessary water consumption and saving water resources; through real-time monitoring of the turbidity detection device 17 and the controller, the rinsing effect of the clothes can be accurately judged, and corresponding program adjustments can be made to ensure the accuracy and stability of the washing process; the turbidity detection device 17 and the controller of the automatic dispensing device 11 can judge whether the rinsing procedure needs to be re-executed according to the turbidity value of the washing water, thereby improving the washing effect and allowing users to have a better washing experience.

[0054] In this embodiment, at least two detection sensors are installed in the water quality detection device 3.

[0055] The detection sensors detect the parameters of the washing water before entering the washing device using corresponding detection sensors respectively; in this embodiment, by setting at least two detection sensors, multiple parameters of the washing water can be detected simultaneously, and different sensors can detect different parameters, such as pH value, dissolved oxygen content, turbidity, etc., comprehensively considering the influence of multiple parameters on the washing effect, and improving the accuracy of judgment; and different detection sensors can finely detect and measure different parameters, can complement and correct each other's errors, and improve the accuracy and reliability of the measurement results; through multiple detection sensors, personalized adjustments can be achieved for different water quality conditions, for example, different parameter thresholds can be set for hard water and soft water respectively to meet the washing needs under different water quality conditions;

[0056] Through real-time monitoring of multiple detection sensors, the parameter values ​​of washing water can be obtained in time. According to different parameter values, the amount of water treatment agent added, water flow rate, etc. can be adjusted in time to meet the washing needs under different water quality conditions and improve the washing effect;

[0057] Through the combined effect of multiple detection sensors, the parameters of washing water can be monitored and controlled in a timely manner, avoiding damage to the washing equipment due to excessively high or low parameters and extending the service life of the equipment.

[0058] In this embodiment, the water quality detection device 3 is configured to detect, respectively, but not limited to, pH value, hardness, sulfide, chloride, and trace metal elements;

[0059] By using multiple detection sensors of the water quality detection device 3 to detect multiple parameters at the same time, the water quality of the washing water can be fully understood, which is not limited to the detection of one parameter, and can provide more comprehensive water quality information; according to the different water quality parameter detection results, the amount and type of water treatment agent added can be accurately adjusted; for example, if the hardness value is high, the amount of softener added can be appropriately increased to reduce the hardness of the water and improve the washing effect; by detecting parameters including trace metal elements, the pollutant content in the washing water can be understood, and according to the detection results, a suitable detergent can be selected to effectively remove pollutants and avoid the reaction between the detergent and the pollutants to produce harmful substances.

[0060] Alternatively, by testing parameters such as sulfide and chloride, we can understand whether there are substances in the washing water that may cause corrosion or damage to the equipment, and take appropriate measures in time, such as adding preservatives or performing water quality treatment, to prevent equipment damage and extend its service life. By testing parameters such as trace metal elements, we can understand whether there are substances in the washing water that are harmful to human health. Based on the test results, we can take appropriate measures, such as choosing a suitable detergent, to protect the health and safety of users.

[0061] The automatic delivery device 11 further comprises a delivery storage device 5, and the automatic delivery device 11 adds corresponding water quality treatment agents in the delivery storage device 5 according to different water quality parameters before entering the washing device;

[0062] According to the water quality parameters before entering the washing device, the automatic dispensing device 11 can add corresponding water treatment agents, which can effectively remove stains, bacteria and odors in the water and improve the washing effect; the automatic dispensing device 11 can intelligently dispense water treatment agents according to the water quality parameters, avoiding the tedious steps of manual addition by users. Users only need to put clothes into the washing device and select the washing program. The automatic dispensing device will automatically dispense an appropriate amount of water treatment agents according to the water quality parameters, simplifying the user's operation process.

[0063] In this embodiment, at least two current sensors are arranged inside the water quality detection device 3 to detect the acidity and alkalinity of water;

[0064] In addition to using a current sensor to detect the acidity and alkalinity of water quality, the water quality detection device 3 is also provided with a water quality parameter detection sensor to detect other water quality parameters; In addition to using a current sensor to detect the acidity and alkalinity of water quality, the water quality detection device 3 is also provided with a water quality parameter detection sensor to detect other water quality parameters, such as turbidity, dissolved oxygen, conductivity, etc., so as to provide comprehensive water quality information and help users understand the water quality status more accurately;

[0065] The current sensor and the water quality parameter detection sensor can provide high-precision water quality detection. By accurately detecting the acidity and alkalinity of the water and other water quality parameters, it can be determined whether the water quality meets the requirements and timely adjustments can be made. Since a plurality of sensors are arranged inside the water quality detection device 3, changes in water quality parameters can be monitored in real time. Once abnormal water quality is found, such as excessively high acidity and alkalinity or other parameters exceeding the set range, the automatic dispensing device 11 can make corresponding adjustments in time according to the detection results to prevent water quality problems from having a negative impact on the washing effect.

[0066] In this embodiment, the controller includes a communication module connected to the cloud platform.

[0067] The communication module is used to upload the water quality test results to the cloud platform and obtain the parameter ratios of the dosing agent for different water quality parameters from the cloud platform;

[0068] By connecting to the communication module of the cloud platform, the water quality test results can be uploaded to the cloud platform in a timely manner, which can realize real-time monitoring and data recording of water quality parameters, making it convenient for users to view historical data and understand the changing trend of water quality;

[0069] The cloud platform can provide corresponding dosing agent parameter ratios according to different water quality parameters. Through the interaction between the communication module and the cloud platform, the controller can obtain these ratios and adjust them as needed. This can realize intelligent water quality treatment and automatically adjust the amount of dosing agent according to the real-time water quality test results and the ratio provided by the cloud platform to achieve the best washing effect.

[0070] In this embodiment, the cloud platform can also be configured to analyze and process the uploaded water quality test data, generate water quality trend graphs, statistical reports, etc.; by analyzing a large amount of real-time data, the causes and patterns of water quality problems can be identified, and corresponding optimization solutions can be provided, so that the washing strategy and the use of water treatment agents can be continuously improved, the washing effect can be improved, and resources can be saved;

[0071] By connecting to the cloud platform through the communication module, remote monitoring and management functions can be realized. Users can remotely monitor water quality, control washing equipment, adjust the proportion of dosing parameters, etc. anytime and anywhere through mobile phones, computers and other devices; this facilitates user use and management and improves the convenience and flexibility of operation.
