It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.
[0025] refer to Figure 1 The embodiment of the utility model first provides a dishwasher drainage system, including a drainage device, a recovery device, a turbidity detection device and a control device.
[0026] Among them, the drainage device includes a first drainage pipe and a second drainage pipe, one end of the first drainage pipe is connected to the water outlet of the dishwasher tank, and the other end of the first drainage pipe is connected to the sewage pipe; one end of the second drainage pipe is connected to the water outlet of the dishwasher tank, and the other end of the second drainage pipe is connected to the recovery device.
[0027] Specifically, the cleaning water after the dishwasher washes the dishes is discharged through the drainage device. The first drainage pipe of the drainage device is used to discharge the cleaning water of the dishwasher to the sewage pipe, and the second drainage pipe is used to discharge the cleaning water of the dishwasher to the recovery device, and the turbidity of the cleaning water in the first drainage pipe is greater than the turbidity of the cleaning water in the second drainage pipe.
[0028] Many dishwasher cleaning programs are generally one main wash + multiple washes. The first main wash program requires the addition of detergent or dishwashing salt, so the water in the dishwasher cavity after the first wash must contain foam, and the amount of foam is large, so the waste water of the first main wash can generally be discharged directly into the sewage pipe through the first drainage pipe without considering recycling; the second cleaning program mainly rinses the detergent, and the obtained cleaning water contains a small amount of foam, which needs to be checked to confirm whether it meets the recycling standard. If it meets the recycling standard, it will be recycled; the cleaning water obtained by the third cleaning program theoretically does not contain foam, because a small amount of foam should be eliminated during the second cleaning, but it also needs to be tested to confirm whether it meets the recycling standard. If it meets the recycling standard, it will be recycled; and so on, the cleaning water obtained by the Nth cleaning program is tested to confirm whether it meets the recycling standard. If it meets the recycling standard, it will be recycled. For the cleaning water that does not meet the recycling standard, it is discharged to the sewage pipe through the first drainage pipe, and the cleaning water that meets the recycling standard is discharged to the recycling device through the second drainage pipe.
[0029] In a possible embodiment, the drainage device also includes a first drain valve and a second drain valve, the first drain valve is arranged between one end of the first drainage pipeline and the water outlet of the water tank, and the second drain valve is arranged between one end of the second drainage pipeline and the water outlet of the water tank.
[0030] Specifically, the first drain valve is used to control the on-off of the first drain pipe. When the first drain valve is opened, the first drain pipe is connected, and the dishwasher discharges cleaning water through the first drain pipe. When the first drain valve is closed, the first drain pipe is disconnected, and the dishwasher stops discharging cleaning water through the first drain pipe. The second drain valve is used to control the on-off of the second drain pipe. When the second drain valve is opened, the second drain pipe is connected, and the dishwasher discharges cleaning water through the second drain pipe. When the second drain valve is closed, the second drain pipe is disconnected, and the dishwasher stops discharging cleaning water through the second drain pipe.
[0031] For the detection of cleaning water, the utility model adopts a turbidity detection device. In a possible implementation, the turbidity detection device is arranged between the water outlet of the dishwasher's water tank and the drainage device. The turbidity detection device is used to detect the turbidity of the dishwasher's cleaning water and generate turbidity detection information to send to the control device, so that the control device selects to control the drainage pipeline of the drainage device based on the turbidity detection information.
[0032] Specifically, since the turbidity of the washing water in the first drainage pipeline is greater than that in the second drainage pipeline, the washing water needs to be tested for turbidity before discharge to determine whether to use the first drainage pipeline or the second drainage pipeline to ensure the water quality of the recovered washing water. The turbidity detection device is arranged between the water outlet of the dishwasher's water tank and the drainage device, and can detect the turbidity of the washing water before it is discharged, generate turbidity detection information and send it to the control device. If the turbidity detection information indicates that the turbidity of the washing water is not suitable for recovery, the second drainage pipeline is controlled to be closed and discharged to the first drainage pipeline. If the turbidity of the washing water is suitable for recovery, the first drainage pipeline is controlled to be closed and discharged to the second drainage pipeline.
[0033] In a possible implementation, the turbidity detection device is a turbidity sensor, and generates turbidity detection information and sends it to the control device, so that the control device selects to control the opening and closing of the first drain valve or the second drain valve based on the turbidity detection information. Further, when the control device determines that the washing water is greater than a preset turbidity threshold based on the turbidity detection information, the first drain valve is controlled to be opened, and the second drain valve is controlled to be closed; when the control device determines that the washing water does not exceed the preset turbidity threshold based on the turbidity detection information, the second drain valve is controlled to be opened, and the first drain valve is controlled to be closed.
[0034] Regarding the selection of the preset turbidity threshold, in some embodiments, it can be set to 5NTU (turbidity unit), and can be set to other values according to actual needs, which is not limited here.
[0035] The recovery device is embedded in the body of the dishwasher, and is used to recover the washing water discharged by the dishwasher through the second drainage pipe. Specifically, the recovery device recovers the washing water, and the user reuses the washing water, for example, the user can use it in scenes where the water quality requirement is not high, such as watering flowers and mopping the floor, so as to save resources.
[0036] In a possible embodiment, the recycling device includes a recycling container, which is movably embedded in the bottom of the body of the dishwasher, and the other end of the second drainage pipeline is connected to the water inlet of the recycling container. Specifically, the recycling container can be removed from the body of the dishwasher to transfer the washing water recovered therein. In a possible embodiment, the recycling device also includes a disassembly device, which is used to disassemble the recycling container to separate the recycling container from the dishwasher. Specifically, a switch button can be set at the connection between the recycling container and the dishwasher, and a detachable valve can be set on the recycling container. Then, the control button controls the opening and closing of the detachable valve. When the detachable valve is opened, the user can disassemble the recycling container to separate the recycling container from the dishwasher; when the detachable valve is closed, the recycling container is fixedly connected to the dishwasher.
[0037] In a possible embodiment, the recovery device also includes a water level monitoring device, which is arranged on the top of the recovery container, for monitoring the water level of the recovery container, and generating water level monitoring information to send to the control device, so that when the control device determines that the water level of the recovery container reaches a preset water level threshold, it controls the second drain valve to close.
[0038] Specifically, the water level monitoring device can be a water temperature probe or a liquid float, etc., which is electrically connected to the control device to generate water level monitoring information and send it to the control device. When the control device determines that the water level in the recovery container reaches the preset water level threshold, it controls the second drain valve to close, stops the discharge of the washing water, and waits for the user to process the recovered washing water. The preset water level threshold can be selected according to actual conditions, as long as it is ensured that the water in the recovery container does not overflow to affect the dishwasher.
[0039] In addition, in order to improve the user experience and enable the user to more intuitively determine whether the washing water in the recycling container is full, in a possible implementation, a voice prompt module is also provided. When the control device determines that the water level in the recycling container has reached the preset water level threshold, the control device generates a water level alarm message and controls the voice prompt module to play the water level alarm message until the water level in the recycling container is lower than the preset water level threshold. Specifically, the water level monitoring device generates water level monitoring information and sends it to the control device. When the control device determines that the water level in the recycling container has reached the preset water level threshold based on the water level monitoring information, the control device drives the voice prompt module to play water level alarm messages such as "the recycling container is full" and waits for the user to process until the water level in the recycling container is lower than the preset water level threshold and the voice prompt module stops working.
[0040] In a possible implementation, the control device is also used to control the opening and closing of the second drainage pipeline in response to the user's drainage selection instruction. Specifically, the user can select the first drainage pipeline / second drainage pipeline on the operation panel of the dishwasher. When the user does not need to recycle the washing water, the drainage selection instruction directly selects the first drainage pipeline, and the control device controls the first drainage pipeline to open and controls the second drainage pipeline to close. When the user needs to recycle the washing water, the drainage selection instruction selects the first drainage pipeline + the second drainage pipeline, and the control device controls the first drainage pipeline + the second drainage pipeline to open. In this way, the user can make a choice according to the needs, which improves the user experience.
[0041] In another aspect, a dishwasher is provided, comprising the dishwasher drainage system as described above.
[0042] Next, the logic of using the above dishwasher drainage system is introduced, including the following steps:
[0043] The user can select the first drainage pipeline / second drainage pipeline on the operation panel of the dishwasher. When the user does not need to recycle the washing water, the drainage selection instruction directly selects the first drainage pipeline, and the control device controls the first drainage pipeline to open and controls the second drainage pipeline to be closed. When the user needs to recycle the washing water, the drainage selection instruction selects the first drainage pipeline + the second drainage pipeline, and the control device controls the first drainage pipeline to open, and the second drainage pipeline is opened in time according to the turbidity of the washing water. After each washing program is completed, the turbidity detection device detects the turbidity of the washing water of the dishwasher, and generates turbidity detection information and sends it to the control device. When the control device determines that the washing water is greater than the preset turbidity threshold based on the turbidity detection information, the first drainage valve is controlled to open, and the second drainage valve is controlled to close, and the washing water is discharged to the sewage pipeline through the first drainage pipeline; when the control device determines that the washing water does not exceed the preset turbidity threshold based on the turbidity detection information, the second drainage valve is controlled to open, and the first drainage valve is controlled to close, and the washing water is discharged to the recovery container through the second drainage pipeline. The water level monitoring device monitors the water level of the recovery container and generates water level monitoring information and sends it to the control device, so that when the control device determines that the water level of the recovery container has reached the preset water level threshold, it generates water level alarm information and drives the voice prompt module to play water level alarm information such as "the recovery container is full", and at the same time controls the second drain valve to close and wait for user processing until the water level of the recovery container is lower than the preset water level threshold and the voice prompt module stops working.
[0044] Through the above embodiments, the dishwasher drainage system of the utility model is provided with a first drainage pipe and a second drainage pipe, the first drainage pipe is used to discharge the cleaning water of the dishwasher to the sewage pipe, and the second drainage pipe is used to discharge the cleaning water of the dishwasher to the recovery device for recycling, and a turbidity detection device is provided to detect the turbidity of the cleaning water to be discharged, and generate turbidity detection information to be sent to the control device. If the turbidity detection information indicates that the turbidity of the cleaning water to be discharged is not suitable for recycling, the second drainage pipe is controlled to be closed and discharged to the first drainage pipe. If the turbidity of the cleaning water is suitable for recycling, the first drainage pipe is controlled to be closed and discharged to the second drainage pipe, thereby realizing intelligent cleaning water recycling and reuse and saving water resources.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
