Description

Control method of additive feeding device and additive feeding device
Technical Field
The invention belongs to the technical field of washing equipment, and particularly relates to a control method of an additive feeding device and the additive feeding device.
Background
When the washing equipment is used for washing clothes, additives such as detergent, softener and the like are required to be added to achieve a better washing effect. The additive may be added manually by a user or automatically by an automatic dispensing device.
When a user manually puts in the additive, the additive feeding amount cannot be accurately controlled, the washing effect can be influenced if the feeding amount is small, the additive is wasted if the feeding amount is large, and the additive cannot be cleaned under the set rinsing times, so that the additive is remained on clothes, and the clothes wearing experience of the user is influenced.
Most of the existing automatic feeding devices are integrated in washing equipment, the size of the automatic feeding devices is limited by the size of the whole washing equipment, the maximum storage capacity of additives is small, frequent replenishment is needed by a user, and the use is inconvenient. The size of the automatic dispensing device also limits the number of types of additives which can be stored in the automatic dispensing device, so that the existing automatic dispensing device can only dispense a single type of detergent or a fixed combination of detergent and softener.
In order to solve the above problems, the prior art provides a feeding device independent of a washing device, and the additive storage amount of the feeding device is not limited by the whole volume of the washing device any more due to the independent arrangement of the feeding device. However, in the above solution, since the feeding device and the washing device have independent control systems, the feeding device cannot directly obtain the operation state of the washing device, and further cannot determine when to feed what kind of additive.
The solution is that the user autonomously judges the operation stage of the washing equipment, operates the feeding device when the additive needs to be fed, and triggers the feeding device to feed the corresponding type of additive, so as to complete the feeding of the additive. However, the operation is complicated due to the need of user intervention, so that the automation degree of the dispensing device is greatly reduced, and the use by the user is inconvenient.
The other solution is to establish communication connection between the throwing device and respective control systems of the washing equipment to realize acquisition of the running process of the washing equipment by the throwing device so as to perform corresponding throwing operation, or directly send a throwing instruction to the throwing device by the washing equipment to control the throwing device to perform throwing operation. However, the above scheme requires the washing apparatus itself to have a communication function, increasing the manufacturing cost of the washing apparatus. Meanwhile, the non-networking type washing equipment cannot use the throwing device due to the fact that the non-networking type washing equipment does not have a communication function, and for users who already own the non-networking type washing equipment, the throwing device cannot meet the requirements of the users on automatic throwing.
In view of the above, the present invention is particularly proposed.

For a general washing device 100, the power consumption condition of the washing device 100 in the operation stages of washing, dewatering, rinsing, etc. is changed greatly, and the additive feeding device 200 can determine the operation stage of the washing device 100 according to the obtained power consumption information, thereby autonomously judging whether to feed additives or not and determining the type of the additives to be fed. The washing device 100 itself does not need to have a communication function, so that the additive feeding device 200 can directly acquire the running state information of the washing device 100, and can automatically and accurately feed different types of additives in the running process of the washing device 100 only by acquiring the power utilization information.
As shown in fig. 3, in a further embodiment of the present invention, the additive feeding device 200 determines the type of the washing program being operated by the washing apparatus 100 and the current operation process according to the obtained power consumption information, and determines the feeding information according to the type of the washing program and the operation process.
In this embodiment, the power supply line 101 connected to the power supply interface 202 of the additive feeding device 200 is connected to a power panel of the washing apparatus 100 to supply power to the whole washing apparatus 100, and the power consumption information obtained by the additive feeding device 200 is one or more of total working current, total working voltage, and total working power of the washing apparatus 100 during working.
Specifically, the washing program type includes a general washing program, a wool washing program, and the like, and the operation course includes wash inlet water, washing, wash drain water, rinse inlet water, rinsing, rinse drain water, rinse dewatering, final dewatering, and the like. Different types of additives need to be dosed during different runs of different washing programs. For example, in the washing water inlet process of the conventional washing procedure, a common detergent needs to be added, in the rinsing water inlet process, a softener does not need to be added or added, and in the washing water inlet process of the wool washing procedure, a wool-specific detergent needs to be added.
In the above scheme, after the additive feeding device 200 acquires the power consumption information of the washing apparatus 100, the type and the operation progress of the washing program are determined, so that the additive feeding device can adapt to more diversified washing programs and complete a more complicated automatic feeding process. Especially under the condition that the standard of living improves gradually, the material of clothing is abundanter among the daily life, and people also are more diversified to the demand that the clothing was washed and is protected, and the additive of this embodiment is put in device 200 and can be accomplished complicated automatic input process to the realization is washed and is protected special or high-end clothing is careful, has improved user experience.
In this embodiment, the additive feeding device 200 is pre-provided with a plurality of power utilization models respectively corresponding to different operation courses of different washing program types. The additive feeding device 200 compares the acquired power consumption information with the power consumption model to acquire the power consumption model matched with the power consumption information, and determines the type and the operation process of the washing program.
The power usage models corresponding to different operation courses of different washing program types are written in advance in a control system, such as a computer board or a control chip, of the additive dispensing device 200. The specific implementation manner of this embodiment is to collect the power consumption conditions of the washing device 100 in advance in different operation courses of different washing program types, generate a plurality of power consumption models according to the collected power consumption conditions, and write the power consumption models into the control system of the additive feeding device 200 as a judgment basis. When the additive feeding device 200 works, the power consumption models are compared among the plurality of power consumption models, and the power consumption model matched with the acquired power consumption information is found out, so that the type of the washing program operated by the washing equipment 100 and the current operation process can be correspondingly found out.
In a specific scheme of this embodiment, the electricity consumption information is a detected electricity consumption parameter value, and the electricity consumption model is a preset electricity consumption parameter value range. And when the electricity utilization parameter value falls into the electricity utilization parameter value range, judging that the acquired electricity utilization information is matched with the electricity utilization model.
For example, the additive feeding device 200 obtains that the current working current value of the washing apparatus 100 is I, and a preset power utilization model in the additive feeding device 200 is the interval of the working current value [ I [ ] 10 ,I 20 ) And (4) inside. If I 10 ≤I<I 20 Then, it is determined that the acquired power consumption information matches the power consumption model, so as to determine that the washing program type and the operation process corresponding to the power consumption model are the washing program type and the operation process currently operated by the washing apparatus 100.
In another specific scheme of this embodiment, the power consumption information is a variation curve of a detected power consumption parameter value, and the power consumption model is a preset power consumption parameter variation curve; and when the correlation ratio between the detected change curve and the preset power utilization parameter change curve is larger than a preset value, judging that the acquired power utilization information is matched with the power utilization model.
For example, the additive feeding device 200 obtains the total operating current value of the washing apparatus 100 in real time and obtains the variation curve of the total operating current, and continuously compares the total operating current value with a plurality of preset current variation curves, and determines that the total operating current value and the variation curve are matched when the correlation ratio of the total operating current value and any current variation curve is greater than a preset value, so as to determine the type of the washing program currently operated by the washing apparatus 100 and the operation process of the washing apparatus.
In the above scheme, the additive feeding device 200 presets a plurality of power utilization models for matching with the acquired power utilization information, so that the additive feeding device 200 can autonomously judge the type of the washing program operated by the washing equipment 100 and the current operation process, and further can determine feeding information without user operation intervention, thereby realizing real automatic feeding and having high intelligent degree.
In a further aspect of this embodiment, after determining the type of the washing program, the additive feeding device 200 determines whether the type of the washing program includes a running process repeated at least twice. And when the washing program type comprises repeated running processes, counting the times of matching the electricity utilization information with the electricity utilization model corresponding to the repeated running processes, and determining the putting information according to the times of matching.
Some types of washing programs may include multiple repeated operation cycles in which the power consumption of the washing apparatus 100 is substantially the same, but the need for additive delivery may vary. For example, for a conventional washing program, three phases of washing, rinsing and final dewatering are generally included, wherein the rinsing phase may include two or more times from the start of rinsing water intake to the end of rinsing dewatering. In each rinsing water inlet process, the power consumption of the washing device 100 is substantially the same, that is, the power consumption information obtained by the additive feeding device 200 is substantially the same. However, the softener is only needed to be put in the last rinsing water inlet process, and the additive is not needed to be put in the previous rinsing water inlet process.
In the above scheme, for the type of the washing program including the repeated operation process, the additive feeding device 200 also counts the number of times that the acquired electricity consumption information is matched with the same electricity consumption model, and determines the feeding information according to the type of the washing program, the operation process and the number of times that the matching occurs, so that different feeding operations can be performed in the repeated operation process, the control of the feeding process is more accurate, and the condition of mistaken feeding is further avoided, for example, the condition of feeding the softener in every rinsing water can be avoided.
Specifically, if the washing program type determined by the additive feeding device 200 includes N rinsing water inlet courses, the additive feeding device 200 does not feed electricity when the electricity consumption information matches the electricity consumption model corresponding to the rinsing water inlet course from the first time to the (N-1) th time; and when the nth time of the electricity utilization information is matched with the electricity utilization model corresponding to the rinsing water inlet process, the additive feeding device 200 feeds the softener.

Example two
The present embodiment is different from the first embodiment in that: the power consumption information comprises independent power consumption data of at least one electrical component in the washing equipment.
Specifically, the power supply line connected to the additive feeding device no longer supplies power to the whole washing device, but is only connected to one or more electrical components in the washing device to supply power to one or more electrical components individually, and the rest of the electrical components supply power through other circuits. At this time, the electricity consumption information detected by the electricity consumption detection module is only the independent electricity consumption data of one or more electrical components connected with the power supply line, and the overall electricity consumption parameter of the washing equipment is not acquired any more.
In a preferred embodiment of this embodiment, the electrical component includes a water inlet valve and/or a motor. The independent electricity data comprises one or more of the working current, the working voltage and the working power of the electric appliance component.
Table 1 shows a plurality of operation courses included in one type of washing program, and electric components and power consumption thereof that operate in different operation courses, taking an operation current as an example.
TABLE 1 run course and action current in washing program
Figure BDA0003019640440000141
It should be noted that, in table 1, the operation process from the rinsing water supply to the rinsing water drain may be repeated many times, and the specific values of the coefficients a, b, and c in the parameter formula may be different for different washing programs and different operation processes.
As can be seen from table 1 above, in different operation processes, the electrical components that operate are different, and if only the total operating current of the washing apparatus is detected, the action current values of the electrical components are superimposed, so that the total current values obtained after the superimposition are closer to each other in different operation processes, which may further affect the judgment of the operation process by the additive feeding device, resulting in feeding errors.
The feeding of the additive occurs in the water inlet process, and only the water inlet valve and the motor act in the water inlet process, and other electrical elements do not act. The additive feeding device independently detects the action current of the water inlet valve and the motor, judges the type of the currently running washing program and whether the current washing program is a water inlet process needing to feed the additive or not according to the detection result, and then feeds the corresponding additive.
In this embodiment, power consumption parameters, such as an operating current, of different electrical components in the washing apparatus during operation are collected in advance, and the power consumption parameters are written into a control system of the additive feeding device as a judgment basis. And when the additive feeding device works, the real-time action current of the related electric appliance component is obtained in real time, and is compared with the written action current numerical range or the action current change curve, the type and the running process of the washing program are judged, and the feeding process is further controlled.
In the scheme, the additive feeding device can be used for acquiring the independent power utilization data of the electric appliance parts related to the water inlet process in a targeted manner, so that the accuracy of judging the type and the operation process of the washing program is improved, the accuracy of additive feeding control is improved, and the probability of error feeding is reduced.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
