[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0025] like Figure 1 As shown, an exemplary embodiment of the present invention provides a dishwasher, which is used to wash tableware such as dishes to be washed to ensure the cleanliness of the tableware and the next use. It should be noted that the dishwasher in this example may include but is not limited to a spray dishwasher or an ultrasonic dishwasher.

[0026] The dishwasher is provided with a cleaning area for cleaning dishes. The dishwasher is provided with a first water inlet and a second water inlet connected to the cleaning area. It should be noted that in this example, the first water inlet is assumed to be the normal inlet for the washing medium, that is, the washing medium whose turbidity value meets the use requirements enters the dishwasher through the first water inlet each time.

[0027] A diverter device is arranged inside the dishwasher and beside the cleaning area. The diverter device may have two water outlets, which are respectively connected to the first water inlet and the second water inlet. It should be noted that the diverter device may include but is not limited to a three-way valve, a Y-type diverter pipe, etc.

[0028] Continue to refer to Figure 1 As shown, a water purification device is also provided inside the dishwasher and beside the cleaning area, and the water purification device is used to purify the washing medium for cleaning the dishes. It should be noted that the water purification device can adopt a filtering water purification device in the prior art, for example, the water purification device can be a reverse osmosis water purification system, a water purifier, etc. Among them, the water inlet end of the water purification device is connected to the water outlet end of the cleaning area, and the water outlet end of the water purification device is connected to the second water inlet. The water inlet end of the first water inlet can be directly connected to the input end of the washing medium. The washing medium can include but is not limited to tap water, purified water, etc.

[0029] The dishwasher is equipped with a turbidity sensor for detecting the turbidity value of the washing medium. The detection principle of the turbidity sensor is to emit near-infrared light into the washing water and then receive the light reflected by the suspended particles for measurement. When the light passes through a certain amount of water, the amount of light transmitted depends on the degree of turbidity of the water. The dirtier the water, the less light is transmitted. The light receiving end converts the intensity of the transmitted light into the corresponding current size. The more light is transmitted, the larger the current is. Conversely, the less light is transmitted, the smaller the current is. By measuring the magnitude of the current at the receiving end, the degree of turbidity of the water can be obtained.

[0030] There may be more than one turbidity sensor, a turbidity sensor may be arranged at the inlet end of the diversion device, a turbidity sensor may be arranged upstream of the second water inlet, and a turbidity sensor may be arranged at the outlet end of the cleaning area.

[0031] That is, when the dishwasher needs to clean the dishes, the user starts the cleaning program, and at this time, the washing medium enters the cleaning area through the first water inlet to process the dishes. The washing medium after cleaning flows out from the water outlet of the cleaning area, and then the turbidity value of the washing medium at this time is obtained by the turbidity sensor inside the dishwasher. Then, the control module based on the dishwasher compares the turbidity value with the preset turbidity value, and determines whether the washing medium at this time is sewage based on the comparison result.

[0032] The preset turbidity value may be a theoretical value or an empirical value set when the dishwasher leaves the factory, and is not specifically limited here.

[0033] When the turbidity value is less than the preset turbidity value, it indicates that the turbidity value of the washing medium is relatively small at this time, and the tableware can be continuously cleaned and used for the next time.

[0034] When the turbidity value is greater than the preset turbidity value, it indicates that the turbidity value of the washing medium is high at this time, and the control module based on the dishwasher determines that the washing medium is sewage. If the washing medium in this state continues to be used to clean the tableware, the tableware will be less clean and cannot meet the requirements for the next use of the tableware. Therefore, when the turbidity value of the washing medium is greater than the preset turbidity value, the washing medium flowing out of the water outlet of the cleaning area enters the water purification device through the second water inlet, so as to purify the washing medium through the water purification device, effectively reduce the turbidity value of the washing medium, and thus ensure the use requirements of the washing medium.

[0035] It should be noted that, in the process of the water purification device purifying the washing medium, the control module based on the dishwasher constantly obtains the turbidity value of the washing medium at this time, and continues to compare the turbidity value of the washing medium at this time with the preset turbidity value. When it is determined that the washing medium is not sewage according to the comparison result at this time, the washing medium is controlled to perform the next washing process. When it is determined that the washing medium is still sewage according to the above comparison result, the washing medium continues to be re-delivered to the water purification device through the second water inlet, or the internal circulation system in the water purification device is used to re-purify the washing medium for the second time. Repeat the above process multiple times, and constantly obtain the turbidity value of the washing medium during this period. Only when the turbidity value of the washing medium is less than the preset turbidity value, can the washing medium be input into the cleaning area to clean the tableware.

[0036] In this example, after the water purification device performs at least one purification process on the washing medium, the turbidity value M1 of the washing medium is obtained. When the turbidity value M1 is less than the preset turbidity value B but greater than the first turbidity value A, that is, A<M1<B, the washing medium at this time can be used for the next washing process of the tableware, but the washing medium in this state cannot be used for other household water equipment such as water dispensers.

[0037] When the turbidity value M1 is greater than the preset turbidity value B but less than the second turbidity value C, that is, B<M1<C, the turbidity value M1 of the washing medium at this time is relatively high. The washing medium with the turbidity value M1 cannot be directly used in the next washing process of the tableware, that is, it cannot be used in the dishwasher. It is necessary to perform corresponding subsequent operations on the washing medium again, such as multiple purification treatments or discharge for other uses, such as cleaning items, kitchen utensils, furniture, watering flowers, washing cars, etc.

[0038] Also, when the turbidity value M1 is greater than the second turbidity value C but less than the third turbidity value D, that is, C<M1<D, it indicates that the turbidity value M1 of the washing medium is too high at this time, and the washing medium with the turbidity value M1 cannot be used directly for washing tableware. At the same time, the washing medium with the turbidity value M1 cannot be directly used in household water-using equipment such as water heaters, so as to avoid the washing medium with the turbidity value M1 causing poor tableware washing effect or affecting the use of the water heater, etc.

[0039] When the turbidity value M1 is greater than the third turbidity value D, that is, D<M1, it indicates that the turbidity value of the washing medium is too high at this time, that is to say, the washing medium with the turbidity value M1 cannot be directly used for washing tableware. Similarly, the washing medium in this state cannot be directly used for other household water-using equipment, such as water dispensers, dishwashers, water heaters, and washing machines.

[0040] It should be noted that the washing medium after cleaning the tableware once flows out from the water outlet of the cleaning area, and then the turbidity value M1 of the washing medium at this time is obtained by using the turbidity sensor. When A<M1<D, the control module of the dishwasher sends out a corresponding reminder message, wherein the reminder method of the reminder information may include but is not limited to a reminder on the control interface of the dishwasher, a voice reminder, or a reminder through the user's smart device, such as an App information reminder in a mobile phone or smart tablet.

[0041] The reminder information varies according to the range of the turbidity value M1. Among them, when A<M1<B, a first reminder message is issued, and the first reminder message is: the current water quality cannot be used for water dispensers. When B<M1<C, a second reminder message is issued, and the second reminder message is: the current water quality cannot be used for water dispensers and dishwashers. When C<M1<D, a third reminder message is issued, and the third reminder message is: the current water quality cannot be used for water dispensers, dishwashers and water heaters. When D<M1, a fourth reminder message is issued, and the fourth reminder message is: the current water quality cannot be used for household water equipment such as water dispensers, dishwashers, water heaters and washing machines.

[0042] like Figure 2 As shown, an exemplary embodiment of the present invention provides a control method for a dishwasher, and the control method for a dishwasher is applied to the dishwasher in the above embodiment. The control method for a dishwasher includes the following steps:

[0043] Step S100: obtaining an initial turbidity value of the washing medium entering the dishwasher each time.

[0044] Step S200: Compare the initial turbidity value with the preset turbidity value.

[0045] Step S300: Based on the comparison result, determine whether the washing medium in the current washing process is sewage.

[0046] Step S300: when it is determined that the washing medium is sewage, at least one sewage treatment operation is performed on the washing medium, and after each sewage treatment operation is completed, subsequent operations are performed on the washing medium according to each sewage treatment detection information.

[0047] In step S100, an initial turbidity value of the washing medium that enters the dishwasher and cleans the dishes in the cleaning area each time may be obtained by one of the turbidity sensors provided in the dishwasher.

[0048] In step S200 and step S300, the control module of the dishwasher obtains the above-mentioned initial turbidity value, and compares the initial turbidity value with the preset turbidity value preset in the control module through the control module. Then, the control module determines whether the washing medium in the current washing process is sewage according to the comparison result.

[0049] Among them, when the initial turbidity value is less than the preset turbidity value, it can be determined that the current washing medium is not sewage. Then, the control module of the dishwasher controls the washing medium to re-enter the dishwasher through the first water inlet and execute the next washing process.

[0050] In step S400, when the initial turbidity value is greater than the preset turbidity value, it can be determined that the current washing medium is sewage. At this time, the washing medium needs to be treated to reduce the turbidity value of the washing medium. When the washing medium is judged to be sewage, the sewage is discharged through the water outlet of the cleaning area, and the washing medium is drained into the water purification device through the second water inlet. The washing medium is subjected to at least one sewage treatment operation through the water purification device, and after each sewage treatment operation is completed, the washing medium is subjected to subsequent operations according to each sewage treatment detection information. Among them, when the turbidity value of the treated washing medium is less than the preset turbidity value, the next washing process can be performed; and when the turbidity value of the treated washing medium is still greater than the preset turbidity value, the current washing medium can be discharged for other purposes, such as washing items, kitchen utensils, furniture, watering flowers, washing cars, etc.

[0051] In this embodiment, the initial turbidity value of the washing medium entering the dishwasher each time is first obtained, and then based on the comparison result of the initial turbidity value and the preset turbidity value, it is determined whether the washing medium in the current washing process is sewage; when the washing medium is determined to be sewage, at least one sewage treatment operation is performed on the washing medium, and after each sewage treatment operation, subsequent operations are performed on the washing medium according to each sewage treatment detection information, thereby effectively improving the utilization rate of the washing medium and realizing efficient washing, intelligent processing and subsequent processing of the washing medium.

[0052] like Figure 3 As shown, in some embodiments, when it is determined that the washing medium is sewage, performing at least one sewage treatment operation on the washing medium may include the following process:

[0053] After determining that the initial turbidity value is greater than the preset turbidity value, the washing medium is discharged, and then the discharged washing medium is directed to the water purification device through the second water inlet, so as to perform sewage treatment operation on the washing medium by using the water purification device. The water purification device can adopt a filtering water purification device in the prior art, for example, the water purification device can be a reverse osmosis water purification system, a water purifier, etc.

[0054] Then, refer to Figure 3 As shown, after each sewage treatment operation is completed, the process of performing subsequent operations on the washing medium according to each sewage treatment detection information may include:

[0055] After the water purification device has completed the sewage treatment operation on the washing medium, the turbidity value of the washing medium is continuously detected by the turbidity sensor, so as to obtain the current turbidity value of the washing medium.

[0056] Then, according to the current turbidity value, the washing medium after the sewage treatment operation is selectively treated.

[0057] In one example, the current turbidity value can be compared with a preset turbidity value. When the current turbidity value is less than the preset turbidity value, the control module of the dishwasher controls the washing medium to enter the dishwasher to perform the next washing process on the dishes.

[0058] When the current turbidity value of the washing medium is still greater than the preset turbidity value after at least one sewage treatment operation, the washing medium is continuously subjected to sewage treatment operations for a predetermined number of times using the water purification device, wherein the predetermined number of times is at least one. In a preferred example, the predetermined number of times may be two, three or four times.

[0059] Continue to refer to Figure 3 As shown, after the predetermined number of sewage treatment operations are completed, when the turbidity value of the washing medium is still greater than the preset turbidity value, the control module of the dishwasher controls and issues a reminder message to remind the user of the current state of the washing medium.

[0060] like Figure 3 As shown, in some embodiments, the control module of the dishwasher may issue different reminder messages according to the specific range of the turbidity value M1 of the washing medium.

[0061] When the turbidity value M1 is greater than the preset turbidity value B but less than the second turbidity value C, that is, B<M1<C, the turbidity value M1 of the washing medium at this time is relatively high, and a second reminder message is issued through the control module of the dishwasher. Among them, the second reminder message is: the current water quality cannot be used for water dispensers and dishwashers. The washing medium with the turbidity value M1 cannot be directly used in the next washing process of tableware, that is, it cannot be used in dishwashers, and the washing medium needs to perform corresponding subsequent operations again, such as multiple purification treatments or discharge for other uses, such as washing items, kitchen utensils, furniture, watering flowers, washing cars, etc.

[0062] When the turbidity value M1 is greater than the second turbidity value C but less than the third turbidity value D, that is, C<M1<D, it indicates that the turbidity value M1 of the washing medium is too high, and a third reminder message is issued through the control module of the dishwasher. Among them, the third reminder message is: the current water quality cannot be used for water dispensers, dishwashers and water heaters. The washing medium with the turbidity value M1 cannot be directly used for washing tableware. At the same time, the washing medium with the turbidity value M1 cannot be directly used for household water equipment such as water heaters to avoid the washing medium with the turbidity value M1 causing poor tableware washing effect or affecting the use of water heaters.

[0063] When the turbidity value M1 is greater than the third turbidity value D, that is, D<M1, it indicates that the turbidity value of the washing medium is too high, and the fourth reminder message is issued through the control module of the dishwasher. Among them, the fourth reminder message is: the current water quality cannot be used for household water equipment such as water dispensers, dishwashers, water heaters and washing machines. That is to say, the washing medium with the turbidity value M1 cannot be directly used for washing tableware. Similarly, the washing medium in this state cannot be directly used for other household water equipment, such as water dispensers, dishwashers, water heaters, and washing machines.

[0064] like Figure 3 As shown, when the turbidity value M1 is less than the preset turbidity value B but less than the first turbidity value A, that is, A<M1<B, the control module of the dishwasher sends a first reminder message. The first reminder message is: the current water quality cannot be used for the water dispenser. However, the washing medium at this time can be used for the next washing process of the tableware.

[0065] like Figure 4 As shown, an exemplary embodiment of the present invention further provides a control device for a dishwasher, which includes an acquisition module 10 , a comparison module 20 , a determination module 30 and a processing module 40 .

[0066] Among them, the acquisition module 10 is used to obtain the initial turbidity value of the washing medium entering the dishwasher each time. The comparison module 20 is used to compare the initial turbidity value with the preset turbidity value pre-stored in the dishwasher control module. The judgment module 30 judges whether the washing medium in the current washing process is sewage based on the comparison result. When the judgment module 30 judges that the washing medium is sewage, the processing module 40 is used to perform at least one sewage treatment operation on the washing medium, and after each sewage treatment operation is completed, perform subsequent operations on the washing medium according to each sewage treatment detection information. Among them, the process of performing subsequent operations on the washing medium can refer to the above embodiment, which will not be repeated here.

[0067] like Figure 5 As shown, an exemplary embodiment of the present invention further provides a dishwasher, which includes a processor 101 and a memory 102 connected to the processor 101. The memory 102 is used to store computer executable instructions. The computer executable instructions can be called by the processor 101 and execute the control method of the dishwasher in the above embodiment.

[0068] In the above scheme, the initial turbidity value of the washing medium entering the dishwasher each time is first obtained, and then based on the comparison result of the initial turbidity value and the preset turbidity value, it is determined whether the washing medium in the current washing process is sewage; when the washing medium is determined to be sewage, the washing medium is subjected to at least one sewage treatment operation, and after each sewage treatment operation, subsequent operations are performed on the washing medium according to each sewage treatment detection information, thereby effectively improving the utilization rate of the washing medium and realizing efficient washing, intelligent processing and subsequent processing of the washing medium.

[0069] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
