Description

Technical Field

[0001] The present application relates to the field of smart home appliance technology, and in particular to a dishwasher water quality monitoring method, device, electronic device and storage medium. Background Art

[0002] A dishwasher is a device used to automatically wash tableware such as bowls, cutlery, and dishes. It is mainly divided into commercial dishwashers and household dishwashers. Whether it is a household dishwasher or a commercial dishwasher, the cleaning principle is roughly the same. The water in the water tank installed in the dishwasher is heated. When it reaches a certain temperature, the water and added detergent are sprayed onto the tableware in the bowl basket through a water spray pipe to achieve the effect of cleaning and disinfection.

[0003] Since commercial dishwashers are relatively expensive, most businesses rent dishwashers to clean and disinfect tableware in order to save costs. During the rental period, dishwasher manufacturers will send after-sales personnel to regularly maintain and inspect the dishwashers. As for the maintenance and inspection of household dishwashers, the customer makes a subjective judgment based on the usage and then contacts the after-sales personnel to perform maintenance and inspection on the household dishwasher. The maintenance and inspection process includes cleaning the scale in the water tank inside the dishwasher.

[0004] However, whether it is a common dishwasher or a household dishwasher, when determining how long it takes to clean the scale in the dishwasher's water tank, it is mainly based on human subjective judgment, and the maintenance and inspection cycle of after-sales personnel is often fixed; and the scale formation speed is determined by the workload of the dishwasher and the water quality. When the calcium and magnesium ion content of the water in the water tank that constitutes scale exceeds the normal range, the scale formation speed in the water tank is accelerated, and there will be a deviation from the established maintenance and inspection time cycle, resulting in premature descaling or delayed descaling. Premature descaling will increase the number of descaling times during the use of the dishwasher, resulting in waste of resources; while delayed descaling will have a negative impact on the normal operation of the dishwasher and cause waste of electrical energy resources. Summary of the Invention

[0005] In order to reduce resource waste in dishwashers, the present application provides a dishwasher water quality monitoring method, device, electronic device and storage medium.

[0006] In a first aspect, the present application provides a method for monitoring dishwasher water quality, which adopts the following technical solution:

[0007] A dishwasher water quality monitoring method, comprising:

[0008] Sampling the water in the pre-input water tank to obtain sampled water information, wherein the sampled water information includes water hardness and water turbidity;

[0009] Get the water consumption of the dishwasher in a single day;

[0010] determining the amount of scale precipitation on a single day based on the hardness of the water and the water consumption of the dishwasher on that single day;

[0011] Determining a descaling interval based on the daily scale deposition amount and a preset maximum scale deposition amount;

[0012] When the descaling interval ends, a mode switching instruction is generated to switch the dishwasher to the descaling mode.

[0013] By adopting the above technical solution, first, the sampling water information of the water pre-input in the water tank is obtained, wherein the sampling water information includes the hardness of the water, and the water consumption of the dishwasher in a single day is obtained; the electronic device determines the amount of scale generated by the water consumption of the dishwasher in a single day after heating, that is, the scale precipitation amount in a single day, based on the hardness of the water and the water consumption of the dishwasher in a single day; then, the descaling interval is determined according to the preset maximum scale precipitation amount; when the descaling interval ends, it is determined that the water tank in the dishwasher needs to be descaled, and a mode switching instruction is generated to switch the dishwasher to the descaling mode, thereby starting to remove the scale in the dishwasher water tank, thereby achieving timely cleaning of the scale in the dishwasher before the scale has a negative impact on the dishwasher, thereby avoiding waste of resources due to excessive scale in the heating process of the cleaning water.

[0014] In a possible implementation, the step of obtaining the sampled water information further includes:

[0015] Determine whether the quasi-turbidity of the water exceeds a preset turbidity,

[0016] If so, an alarm instruction is generated and fed back to the display device for display.

[0017] By adopting the above technical solution, after obtaining the sampled water information, it is first determined whether the turbidity of the cleaning water pre-input into the dishwasher for washing dishes meets the preset turbidity. If so, it is determined that the pre-used cleaning water does not meet the human health standards. At this time, an alarm message is generated and sent to the display device set in the dishwasher for display, so as to remind relevant users that the water quality of the cleaning water does not meet the standards and needs to be treated.

[0018] In a possible implementation, obtaining the daily water consumption of the dishwasher includes:

[0019] Get the spraying amount of the sprinkler pipe;

[0020] Get the number of times the dishwasher is cleaned in a single day and the duration of a single cleaning cycle;

[0021] The daily water consumption of the dishwasher is obtained based on the spraying amount of the water spray pipe, the number of times the dishwasher is washed in a single day, and the duration of a single washing of the dishwasher.

[0022] By adopting the above technical solution, the amount of cleaning water sprayed by the spray pipe is obtained when the dishwasher is cleaning, and after the end of a single day, the number of times the dishwasher is cleaned in a single day and the single cleaning time of the dishwasher are obtained. According to the single cleaning time of the dishwasher and the amount of water sprayed by the spray pipe, the water consumption of the dishwasher in a single day is obtained.

[0023] In a possible implementation, obtaining the daily water consumption of the dishwasher includes:

[0024] Acquire first image information, where the first image information represents image information of dishes to be washed before entering the dishwasher;

[0025] determining, based on the first image information, an area ratio of the stain in the first image information;

[0026] Determine whether the area ratio of the stain in the first image information exceeds a preset area ratio,

[0027] If so, a switching instruction is generated to switch the dishwasher to the second cleaning mode.

[0028] By adopting the above technical solution, before the staff puts the dishes to be washed into the dishwasher for washing, they obtain the first image information of the batch of dishes to be washed, and based on the first image information, determine the area ratio of the stains on the batch of dishes to be washed in the first image information. Subsequently, if the area ratio of the stains on the batch of dishes to be washed in the first image information is greater than the preset area ratio, it is determined that the stains on the batch of dishes to be washed are large and need to be washed vigorously, and then a switching instruction is generated to control the dishwasher to switch to the second cleaning mode with stronger cleaning force, so as to clean the batch of dishes to be washed.

[0029] In a possible implementation, the generating of the mode switching instruction then includes:

[0030] At the end of the preset descaling time, second image information is obtained, where the second image information represents image information of the interior of the water tank after the scale in the water tank is cleaned;

[0031] Based on the second image information, determine whether there is residual scale in the water tank,

[0032] If yes, determine the dosage of secondary descaling agent.

[0033] By adopting the above technical solution, after the dishwasher is controlled to switch to the descaling mode, descaling of the scale in the dishwasher water tank begins. At the end of the preset descaling time, second image information representing the internal image of the water tank is obtained. Based on the second image information, it is determined whether there is any residual scale in the water tank. If so, the amount of descaling agent for the second descaling is determined according to the residual scale to ensure that the scale in the water tank can be completely removed.

[0034] In a possible implementation, if yes, determining the amount of the secondary descaling agent includes:

[0035] Sampling the descaling wastewater to obtain wastewater sampling information, wherein the wastewater sampling information includes a descaling agent content;

[0036] Determine whether the descaling agent content is higher than a preset descaling agent content,

[0037] If so, a reuse instruction is generated, and then the recovery device is controlled to input the descaling wastewater into the water tank for secondary descaling.

[0038] By adopting the above technical solution, when it is determined that there is residual scale in the dishwasher water tank, the descaling wastewater is sampled to obtain wastewater sampling information, which includes the descaling agent content. The descaling agent content is then compared with the preset descaling agent content. If the descaling agent content is higher than the preset descaling agent content, it is determined that the descaling agent has not completely reacted with the scale at the end of the preset descaling time. Based on the principles of recycling and saving resources, a re-utilization instruction is then generated to control the recovery device to re-input the descaling wastewater discharged from the water tank into the water tank for secondary descaling.

[0079] The following is combined with Figure 1-3 This application is described in further detail.

[0080] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0081] In order to facilitate understanding of the technical solutions proposed in this application, several elements that will be introduced in the description of this application are first introduced here. It should be understood that the following introduction is only for the convenience of understanding these elements, so as to understand the content of the embodiments of this application, and does not necessarily cover all possible situations.

[0082] 1. Water hardness: refers to the concentration of calcium and magnesium ions in water, including carbonate hardness (that is, calcium and magnesium ions that can be precipitated in the form of carbonates when heated, so it is also called temporary hardness) and non-carbonate hardness (that is, the part of calcium and magnesium ions that cannot be precipitated after heating, also called permanent hardness).

[0083] 2. Water turbidity: The originally colorless and transparent water becomes turbid due to the presence of suspended and colloidal particles in the water. The degree of turbidity is called turbidity.

[0084] 3. Total dissolved solids (TDS): Also known as total dissolved solids, this value is measured in milligrams per liter (mg / L) and indicates the number of milligrams of dissolved solids dissolved in 1 liter of water. TDS refers to the total amount of all solutes in the water, including both inorganic and organic matter. A higher TDS value indicates a higher concentration of dissolved solids. Natural water generally excludes organic matter and molecular inorganic matter, so the salt content is referred to as TDS.

[0085] The embodiment of the present application provides a method for monitoring the water quality of a dishwasher, which is executed by an electronic device, wherein the electronic device is a main control unit located in the dishwasher, Figure 1 The method includes: step S101, step S102, step S103, step S104 and step S105, wherein,

[0086] S101. Sampling water in a pre-input water tank to obtain sampled water information, where the sampled water information includes water hardness and water turbidity.

[0087] By adopting the above technical solution, an information collection device is provided inside the dishwasher and installed at the water inlet of the cleaning water. Before the cleaning water is input into the water tank of the dishwasher, the information collection device samples the cleaning water to obtain cleaning water information including information such as water hardness and water turbidity; the water quality of the cleaning water will directly affect the use of the dishwasher and the profile of the person, resulting in the electronic device obtaining the cleaning water information, i.e., the sampled water information, through the information collection device, and subsequently judging the working status and cleaning effect of the dishwasher and performing corresponding processing based on the sampled water information; wherein the information collection device can be a water hardness tester and a water turbidity meter, which is not specifically limited in this embodiment.

[0088] S102: Obtain the daily water consumption of the dishwasher.

[0089] By adopting the above technical solution, according to people's dining habits, whether it is a commercial dishwasher or a household dishwasher, the dishwasher will be used multiple times a day to wash dishes. The amount of water used for each dishwashing will vary depending on the number of dishes to be washed. Acquiring the water consumption of each dishwashing by the dishwasher and performing corresponding processing will increase the computing power of the electronic device; using each day as a water consumption acquisition unit can reduce the subsequent computing power of the electronic device without affecting the subsequent processing results.

[0090] Specifically, the drain pipe in the dishwasher is equipped with multiple water flow detectors. When the dishwasher is washing dishes, the amount of cleaning water transported by the drain pipe is monitored in real time. At the end of a single day, the electronic device obtains the water consumption of the dishwasher recorded by the water flow detector, and then obtains the water consumption of the dishwasher for a single day; subsequently, the electronic device will monitor the operating status of the dishwasher and the scale in the water tank based on the water consumption of the dishwasher for a single day.

[0091] S103: Determine the amount of scale deposited on a single day based on the hardness of the water and the water consumption of the dishwasher on that single day.

[0092] By adopting the above technical solution, the hardness of water is one of the conditions for calculating the amount of scale generated during the heating process of the cleaning water. Among them, the amount of scale precipitation generated during the heating process of the cleaning water is mainly determined by the temporary hardness contained in the hardness of the water.

[0093] Specifically, the electronic device obtains the hardness of the cleaning water through the information collection device, and after determining the water consumption of the dishwasher in a single day, multiplies the water hardness by the water consumption of the dishwasher in a single day in units of mg / L, and then determines the amount of scale generated after heating the water consumption of the dishwasher in a single day, that is, the amount of scale precipitation in a single day; then, the electronic device uses the amount of scale precipitation in a single day as one of the conditions for judging whether descaling is appropriate.

[0094] S104: Determine the descaling interval based on the daily scale precipitation amount and the preset maximum scale precipitation amount.

[0095] By adopting the above technical solution, a maximum scale deposition amount is preset inside the electronic device according to the capacity and mode of the dishwasher. When the scale in the water tank is cleaned for a long time, due to the poor thermal conductivity of the scale, when the dishwasher heats the cleaning water in the water tank, the time to heat to a certain temperature will be long, which will cause energy waste. In addition, if there is too much scale in the water tank for a long time, it may cause clogging of the water spray pipe, affecting the normal operation of the dishwasher. Therefore, after determining the scale deposition amount for a single day, the electronic device calculates the preset maximum scale deposition amount and the scale deposition amount for a single day by multiple, and then determines the number of days when the scale deposition amount in the dishwasher water tank reaches the preset maximum scale deposition amount, that is, the descaling interval.

[0096] S105: When the descaling interval ends, a mode switching instruction is generated to switch the dishwasher to the descaling mode.

[0097] By adopting the above technical solution, after the electronic device determines the descaling interval, the electronic device will link the descaling interval. As the dishwasher is used, that is, time passes, when the descaling interval ends, the electronic device determines that the water tank in the dishwasher needs to be descaled, and then the electronic device generates a mode switching instruction to switch the dishwasher from the cleaning mode or standby mode to the descaling mode, thereby starting to remove the scale in the dishwasher water tank, thereby achieving timely cleaning of the scale in the dishwasher before the scale has a negative impact on the dishwasher, thereby avoiding waste of resources due to excessive scale during the heating of the cleaning water.

[0098] The present application provides a method for monitoring the water quality of a dishwasher.

[0099] The electronic device obtains the cleaning water information, i.e., the sampled water information, through the information collection device, wherein the sampled water information includes the water hardness; then, the electronic device obtains the water consumption of the dishwasher recorded by multiple water flow detectors, and then obtains the water consumption of the dishwasher in a single day; the electronic device multiplies the water hardness by the water consumption of the dishwasher in a single day, and then determines the amount of scale generated by the water consumption of the dishwasher in a single day after heating, i.e., the scale precipitation amount in a single day; then, the electronic device multiplies the preset maximum scale precipitation amount by the scale precipitation amount in a single day, and then determines the water hardness of the dishwasher. The scale deposited amount in the tank reaches the preset maximum scale deposited amount, that is, the descaling interval; when the descaling interval is over, the electronic device determines that the water tank in the dishwasher needs to be descaled, and then the electronic device generates a mode switching instruction to switch the dishwasher from cleaning mode or standby mode to descaling mode, thereby starting to remove the scale in the dishwasher water tank, thereby achieving timely cleaning of the scale in the dishwasher before the scale has a negative impact on the dishwasher, thereby avoiding excessive scale in the process of heating the cleaning water, resulting in reduced heat transfer and waste of resources.

[0100] In a possible implementation of the embodiment of the present application, in step S101, sampled water information is obtained, and then the following steps are included: determining whether the quasi-turbidity of the water exceeds a preset turbidity; if so, generating an alarm instruction and feeding it back to a display device for display.

[0101] By adopting the above technical solution, the quality of water used in daily life will directly affect people's health, and the purpose of using a dishwasher is to wash dishes to be washed; in order to ensure people's healthy dining, corresponding standards need to be set for the cleaning water used by the dishwasher, among which the turbidity of water is one of the indicators for judging the quality of cleaning water; for example, the turbidity of the cleaning water does not exceed 1 degree, and the standard is set to the preset turbidity. After obtaining the sampled water information, the electronic device first determines whether the turbidity of the cleaning water pre-input into the dishwasher for washing dishes to be washed meets the preset turbidity. If so, it is determined that the pre-used cleaning water does not meet the human health standard. At this time, the electronic device generates an alarm message and sends the alarm message to the display device set in the dishwasher for display, so as to remind relevant users that the water quality of the cleaning water does not meet the standard and needs to be processed.

[0102] Furthermore, the electronic device can also determine whether the water quality of the cleaning water meets the requirements of human health by detecting the pH value and TDS value of the water. A corresponding collection device is installed at the water inlet in the water tank to obtain the pH value and TDS value of the water. The electronic device compares the pH value and TDS value of the water with the corresponding preset information to determine whether the cleaning water meets the standards of human health.

[0103] A possible implementation of the embodiment of the present application is to obtain the water consumption of the dishwasher in a single day in step S102, including: obtaining the spraying amount of the water spray pipe; obtaining the number of times the dishwasher is cleaned in a single day and the duration of a single cleaning of the dishwasher; and obtaining the water consumption of the dishwasher in a single day based on the spraying amount of the water spray pipe, the number of times the dishwasher is cleaned in a single day, and the duration of a single cleaning of the dishwasher.

[0104] By adopting the above technical solution, multiple drainage holes are opened on the water spray pipe. When the water tank in the dishwasher heats the cleaning water to a certain temperature, the dishwasher starts to wash the dishes. During this period, the multiple drainage holes opened on the water spray pipe simultaneously spray cleaning water to the dishes to be washed, and the corresponding cleaning time set by the dishwasher starts counting. When the cleaning time ends, the water spray pipe stops spraying cleaning water, and the dishwasher ends the cleaning process.

[0105] Specifically, in order to accurately obtain the daily water consumption of the dishwasher, the electronic device obtains the amount of cleaning water sprayed by the spray pipe when the dishwasher is cleaning, and after the end of the single day, obtains the number of times the dishwasher is cleaned in a single day and the single cleaning time of the dishwasher. The water consumption of the dishwasher for a single cleaning is obtained based on the single cleaning time of the dishwasher and the spray amount of the spray pipe. Subsequently, based on the obtained number of cleaning times of the dishwasher, the water consumption of each cleaning of the dishwasher is added up and calculated to obtain the daily water consumption of the dishwasher.

[0106] A possible implementation of an embodiment of the present application is to obtain the water consumption of the dishwasher in a single day in step S102, which includes: obtaining first image information, where the first image information represents image information of the dishes to be washed before entering the dishwasher; determining the area ratio of the stain in the first image information based on the first image information; and determining whether the area ratio of the stain in the first image information exceeds a preset area ratio. If so, generating a switching instruction to switch the dishwasher to the second cleaning mode.

[0107] By adopting the above technical solution, the dishwasher is provided with multiple cleaning modes, and different cleaning modes correspond to cleaning of different intensities; in order to accurately obtain the water consumption of the dishwasher in a single day, before the staff puts the dishes to be washed into the dishwasher for cleaning, they obtain the image of the batch of dishes to be washed, that is, the first image information, through the image acquisition device, and perform feature recognition on the first image information to determine the area ratio of the stains on the batch of dishes to be washed in the first image information. Then, the electronic device compares the area ratio of the stains on the batch of dishes to be washed in the first image information with the preset area ratio. If the area ratio of the stains on the batch of dishes to be washed in the first image information is greater than the preset area ratio, it is determined that the stains on the batch of dishes to be washed are large and need to be cleaned with strong cleaning. Then, the electronic device generates a switching instruction to control the dishwasher to switch from the default first cleaning mode with weaker cleaning strength to the second cleaning mode with stronger cleaning strength, so as to clean the batch of dishes to be washed.

[0108] It is worth noting that when washing dishes is switched from the first cleaning mode to the second cleaning mode, the spraying amount of the water spray pipe also changes accordingly. According to the spraying amount of the water spray pipe in different cleaning modes, the water consumption of the dishwasher in a single day can be obtained more accurately.

[0109] A possible implementation of an embodiment of the present application is to generate a mode switching instruction in step S105, which then includes: obtaining second image information at the end of the preset descaling time, the second image information representing image information of the interior of the water tank after the scale in the water tank is cleaned; based on the second image information, determining whether there is residual scale in the water tank, and if so, determining the amount of secondary descaling agent to be used.

[0110] By adopting the above technical solution, the electronic device generates a mode switching instruction to control the dishwasher to switch from the cleaning mode or the standby mode to the descaling mode. At this time, the electronic device controls the corresponding descaling agent to be input into the water tank for descaling. At the same time, the descaling time preset inside the electronic device starts timing. When the preset descaling time ends, the descaling of the water tank of the dishwasher is completed in a single time; the image acquisition device located inside the water tank obtains second image information representing the internal image of the water tank, and judges whether there is any residual scale in the water tank by identifying the features of the second image information. If so, the amount of descaling agent for the second descaling is determined according to the residual scale to ensure that the scale in the water tank can be completely removed.

[0111] A possible implementation method of the embodiment of the present application is, if yes, then determining the amount of secondary descaling agent, including: sampling the descaling wastewater to obtain wastewater sampling information, the wastewater sampling information including the descaling agent content; judging whether the descaling agent content is higher than the preset descaling agent content, and if so, generating a reuse instruction, and then controlling the recovery device to input the descaling wastewater into the water tank for secondary descaling.

[0112] By adopting the above technical solution, after the preset descaling time ends, that is, the electronic device controls the dishwasher to switch to the descaling mode, the descaling wastewater generated in the water tank is discharged from the water tank and it is determined that there is residual scale in the dishwasher water tank. During this period, an information collection device is installed at the descaling wastewater outlet for sampling the descaling wastewater and obtaining wastewater sampling information, which includes the descaling agent content. The electronic device then compares the descaling agent content with the preset descaling agent content. If the descaling agent content is higher than the preset descaling agent content, it is determined that the descaling agent has not completely reacted with the scale at the end of the preset descaling time. Based on the principle of recycling and saving resources, the electronic device then generates a re-use instruction to control the recycling device to re-input the descaling wastewater discharged from the water tank into the water tank for secondary descaling, and discharge the descaling wastewater from the water tank after the second descaling preset time ends.
