In the embodiment of the invention, the execution subject of the process is a dishwasher. The dishwasher is provided with a data processing module, the data processing module is used for processing the information fed back by each sensor or data acquisition device and controlling the water inlet mode of the dishwasher, and the data processing module can be a microprocessor such as a single chip microcomputer. Specifically, the water inlet control method is applied to a dish washing machine, the dish washing machine comprises at least two water inlet waterways, and different waterways can correspond to water inlet bodies with different attributes. Fig. 1 shows a flow chart of an implementation of a water inlet control method provided by a first embodiment of the present invention, which is detailed as follows:
in S101, if a preset water inlet triggering condition is met, acquiring the current operation stage of the dishwasher.
In this embodiment, the dishwasher may be configured with a water inlet triggering condition, and when the dishwasher detects that the water inlet triggering condition is currently satisfied, it indicates that the dishwasher needs to perform a water inlet operation. The water inlet operation can be directly used for conveying water to a washing cavity of the dish washing machine, and can also be used for storing water for a water storage part of the dish washing machine so as to be convenient for subsequent operation and use. The water inlet triggering condition may be a time triggering condition, in which case, the dishwasher may configure a plurality of water inlet triggering nodes according to the washing mode and the washing duration, and if the dishwasher detects that the current time reaches the water inlet triggering node, the operation of S101 is executed; the water inlet triggering condition may also be an event triggering condition, in which case, the dishwasher may obtain the washing flowchart corresponding to the current mode, and when a starting instruction of a certain operation is detected, obtain the operation content of the current operation, determine whether the operation content includes a water inlet operation, and if so, execute the operation of S101.
In this embodiment, since the dishwasher may automatically perform the washing operation on the dishes according to a preset washing flow, and the washing process includes a plurality of different washing stages, such as a pre-washing stage, a strong washing stage, a drying stage, and a disinfecting stage, the dishwasher determines the currently executed operation stage when it is determined that the water inlet triggering condition is currently satisfied.
Optionally, when the dishwasher is started, the washing flow and the total washing time of the washing can be determined according to the washing mode selected by the user, if it is detected that the dishwasher meets the water inlet triggering condition, the running time is obtained, the running progress is determined based on the running time and the total cleaning time, and the running stage currently executed by the dishwasher is determined according to the washing flow and the running progress.
In S102, a target waterway is selected from the intake waterways based on the operational phase.
In this embodiment, the dish washer includes many water inlet water ways, and different water inlet water ways are used for the water with different attributes of dish washer transport to can make things convenient for the washing demand of dish washer in different operation stages. For example, need wash the tableware through the sanitizer in strong washing stage, and the sanitizer need just have stronger dissolution rate in the water of uniform temperature, thereby reach better cleaning performance, therefore have certain requirement to this attribute of water temperature, can carry out the operation of intaking to the dish washer through the intake water route that the warm water corresponds this moment, and in the washing stage in advance, then only need directly wash tableware surface residual food waste through the running water can, can carry out the operation of intaking to the dish washer through the intake water route that directly links with the running water pipeline this moment. Therefore, before only water inlet operation is needed, the dishwasher can determine the corresponding water inlet waterway according to the currently executed operation stage information and identify the water inlet waterway as the target waterway. Specifically, the dishwasher may be configured with a correspondence table of phases of operation and incoming waterways, which the dishwasher may query to determine an associated target waterway.
In this embodiment, different water inlet waterways can be connected with waterways where water bodies with different attributes are located, so that the water body type of water inlet operation can be changed according to the switching waterway. For example, the water inlet waterway comprises a first water inlet waterway and a second water inlet waterway, the first water inlet waterway is directly connected with the tap water pipe, the second water inlet waterway is provided with a heating module, and the water flowing through the second water inlet waterway can be heated, namely, the water of the second water inlet waterway is constant-temperature water, the water of the first water inlet waterway is normal-temperature water, and when the dishwasher needs to wash tableware by using the constant-temperature water, the current target waterway can be switched to the second water inlet waterway; and when the dish washer only needs to use normal-temperature water to wash the tableware, the target waterway can be switched to the first water inlet waterway.
Optionally, in this embodiment, the availability of each incoming water circuit may be detected prior to determining the target water circuit. Specifically, the dishwasher can respectively turn on the water inlet switches of the water inlet waterways and record the water inlet amount of the water inlet waterways within a preset detection time; if the water inflow is detected to be larger than a preset water quantity threshold value, identifying a water inlet waterway corresponding to the water inflow as an effective waterway; and if the detected water inflow is less than or equal to the preset water quantity threshold value, identifying the water inlet waterway corresponding to the water inflow as an invalid waterway. The dishwasher selects a target waterway from the effective waterways.
Optionally, in this embodiment, if it is detected that the water inlet waterway associated with the operation phase is an invalid waterway, the waterway abnormality information may be output to notify the user of performing abnormality repair on the invalid waterway; if the repair completion information about the invalid waterway, which is fed back by the user, is received, the dishwasher can start the water inlet part of the invalid waterway and detect the water inlet quantity of the invalid waterway within the detection time again, and if the water inlet quantity is greater than a preset water quantity threshold value, the invalid waterway is identified as the valid waterway.
Optionally, in this embodiment, if it is detected that the water inlet waterway associated with the operation stage is an invalid waterway, the water attributes of the remaining effective waterways may be obtained, the similarity between the water attributes of the water inlet waterways associated with the operation stage is calculated, and the other effective waterways with the highest similarity are selected as the water inlet waterway of the water inlet operation, so that a situation that the washing operation cannot be executed due to the abnormality of the associated water inlet waterway can be avoided, and the robustness of the dishwasher is improved.
In S103, a water inlet part of the target waterway is turned on, and a water inlet operation is performed on the dishwasher through the target waterway.
In this embodiment, dish washer has then opened the part of intaking in target water route after having confirmed the target water route, and the different water routes of intaking correspond an independent part of intaking to can realize opening corresponding water route's purpose alone, after the part of intaking is opened, then the water can be carried in the dish washer with the water route of intaking, thereby carry out the water inlet operation of current stage.
Optionally, in this embodiment, an operation stage may correspond to a plurality of target waterways, that is, the operation stage may be operated by a plurality of waterways simultaneously in the operation process, and may further be configured with water inlet trigger nodes for different waterways, thereby implementing washing operations of tableware in a dishwasher by a plurality of water bodies simultaneously. Specifically, a plurality of washing areas can be configured in a washing cavity of the dishwasher, and different washing areas are used for washing different types of tableware, in this case, different washing areas can correspond to different water outlet components, and each water outlet component can be connected with a corresponding water inlet waterway, so that the properties of water bodies used by different water outlet components can be different, that is, a plurality of waterways can be fed in concurrently, in this case, the dishwasher can determine a target waterway associated with each water outlet component, and simultaneously start the water inlet component of each target waterway to perform water inlet operation on each water outlet component. Specifically, the dishwasher may further be configured with a plurality of different water inlet trigger nodes, and determine target waterways associated with the trigger nodes at different times, and when detecting that the current time reaches the time trigger node, the dishwasher may close the water inlet component of the water inlet waterway of the previous time trigger node, and open the water inlet component of the target waterway of the current time trigger node, thereby implementing a serial water inlet operation.
As can be seen from the above, in the water inlet control method provided in the embodiment of the present invention, at least two water inlet waterways are configured in the dishwasher, different water inlet waterways correspond to water inlet bodies with different attributes, if a water inlet operation needs to be performed in an operation process of the dishwasher, a current operation stage is identified, a corresponding target waterway is selected based on the operation stage, and the water inlet operation is performed on the dishwasher through the target waterway, so that a matched water body can be automatically selected based on the operation stage. Compared with the existing dish washing machine, the embodiment of the invention does not need the user to manually change the attribute of the water inlet body, and can match the water body required by the current washing stage by switching the water inlet waterway connected with different water bodies, thereby realizing the aim of automatically changing the water inlet body, improving the washing efficiency, reducing the operation of the user and further improving the automation degree.

further, the water inlet waterway comprises a primary waterway and a secondary waterway; the selecting a target waterway from the intake waterways based on the operating phase comprises:
in S1021, the water quality index associated with the operation stage is queried based on a preset water quality index list.
In the embodiment, the dishwasher is provided with at least two water inlet paths, wherein the water inlet paths at least comprise a primary water path and a secondary water path, and before the water inlet paths are used, water in the primary water path does not need to be pretreated, namely, water obtained from a water taking position directly flows into a washing cavity of the dishwasher; the water in the secondary water path needs to be pretreated before being supplied to the dishwasher, for example, the water can be filtered by a relevant filter element, or relevant cleaning agents can be dissolved in advance. The original water body of the secondary waterway can be the same as the water body of the primary waterway, for example, the original water body of the secondary waterway can also be tap water, and after the tap water is subjected to relevant pretreatment operation, corresponding secondary water is obtained. Optionally, the original water body of the secondary waterway may be different from the water body of the primary waterway, for example, the primary waterway is connected to a tap water pipeline, that is, the water body of the primary waterway is tap water; the secondary water way is connected with a water storage device provided by a user, namely, the primary water body of the primary water way is pre-stored water provided by the user, and the pre-stored water can be distilled water, mineral water or water body dissolved with a cleaning agent.
In this embodiment, the dishwasher may configure corresponding water quality index lists for different washing stages, so as to define the requirements of each operation stage on the water quality. For example, in the pre-cleaning stage, the requirement on the water quality is low, and the water quality index is small; and in the final stage of the washing operation, the requirement on the water quality is higher, and the water quality index is larger. Optionally, the water quality index is used to indicate the cleanliness of the water.
In S1022, if the water quality index is smaller than a preset index threshold, the native waterway is identified as the target waterway.
In this embodiment, if the dishwasher detects that the water quality index corresponding to the current operation stage is less than the preset index threshold, it indicates that the dishwasher can be directly subjected to water inlet operation through the native water path, and at this time, the native water path can be identified as the target water path.
In S1023, if the water body command index is greater than or equal to the index threshold, identifying the secondary waterway as the target waterway.
In this embodiment, if the dishwasher detects that the water quality index corresponding to the current operation stage is greater than or equal to the preset index threshold, it indicates that the requirement of the current washing operation cannot be met if the water quality index directly passes through the original tap water, and in order to improve the use experience of the user and the cleanness degree of the tableware after the washing operation, the dishwasher needs to perform relevant pretreatment operation on the original water, i.e., generate a corresponding secondary water, and perform washing operation on the dishwasher through the secondary water, so that the secondary water is identified as a target water path, and the water is pretreated through the pretreatment component configured in the secondary water path. The pretreatment components include, but are not limited to: a filter unit, a temperature raising unit, a reagent adding unit, and the like.
In the embodiment of the invention, the water quality index of the current operation stage is determined, so that the associated water inlet waterway is selected as the target water body according to the index, the corresponding water inlet operation can be carried out according to the requirements of different stages on the water quality, and the tableware cleaning effect is improved.

The secondary water path comprises a soft water filtering component and a heating component. Wherein, soft water filter element mainly carries out soft water treatment through carrying out the primary water to improve the clean degree of water. The relatively common raw water body of the dishwasher is tap water, and the tap water contains a certain amount of mineral substances, and if the tap water pipe is used for a long time, rust appears on the inner wall, increasing the content of various metal elements in the tap water, so that the dishwasher needs to perform soft water treatment operation on the raw water body in order to reduce the residue of the mineral substances and the salt containing the metal elements on tableware in the cleaning process.
In this embodiment, the dishwasher may open the water valve switch of the soft water filter unit disposed on the secondary water path, so that the original water may flow into the soft water filter unit.
In S1032, the water body is filtered by the soft water filtering unit, and the filtered water body is heated.
In this embodiment, the dishwasher can filter the soft water of water inflow through the soft water filter element after detecting that the water flows into the soft water filter element, thereby ensuring that the relevant index function of the output water meets the index requirement of the soft water body. The water outlet of the soft water filtering component is connected with the heating component, and after soft water treatment, the filtered water body can be heated by the heating component.
In S1033, if it is detected that the water temperature of the water body reaches a preset temperature threshold, the heated water body is delivered into a washing cavity of the dishwasher, and the washing operation of the operation phase is performed.
In this embodiment, the dishwasher can detect the water temperature of the water body in the heating process, and after detecting that the water temperature reaches a preset temperature threshold, the dishwasher indicates that the heating operation is completed.
In the embodiment of the invention, the soft water filtering component and the heating component are used for pretreating the water body to generate the secondary water body, so that the washing effect of the dish washing machine is improved.
