The fault point of the specific washing machine may be determined according to the current energy consumption parameter value exceeding the preset energy consumption parameter value. For example, when the current power consumption exceeds the preset power consumption, it may be determined that a link of the washing machine consuming power fails, such as a motor, a heating module, and the like of the washing machine.

In a specific implementation manner of the embodiment of the invention, the fault point can be warned by giving an early warning to a washing machine user or a maintenance worker to check and maintain the washing machine aiming at the fault point in time, so as to avoid energy waste. The early warning mode for the washing machine user can be washing machine early warning or terminal (mobile phone, sound, computer or other household appliances) early warning bound with the washing machine. For example, a washing machine buzzer sound warning, a mobile phone or computer pop window warning, a washing machine voice broadcast warning, or a sound broadcast warning, etc. The user can maintain by oneself, contact maintenance personal as required, or send the maintenance demand to the backstage system of washing machine through washing machine or terminal, request maintenance personal to maintain.

As shown in fig. 2a, the method comprises:

and step 210, determining the current power consumption of the washing machine in the current washing.

Fig. 2b is a flowchart of an early warning method for a washing machine according to a second embodiment of the present invention, and as shown in fig. 2b, a power consumption evaluation unit may be disposed on the washing machine, and after the washing is finished, the power consumption evaluation unit may evaluate the power consumption of the washing machine, or may accumulate the power consumption in a preset period (month, quarter, year, etc.). And can set up the early warning unit on washing machine, carry out the early warning when the power consumption in presetting the cycle exceeds the early warning line, the user of being convenient for is visual, transparent and controllable to power consumption. The power consumption evaluation unit may be implemented by evaluating a voltage or current measurement device.

And step 220, when the current power consumption exceeds the preset power consumption, determining a fault point of the washing machine, and performing early warning based on the fault point to prompt maintenance.

The preset power consumption can be obtained based on power consumption measurement when the power consumption link of the washing machine is in fault, and can also be set to be 1.0-1.2 times of the power consumption corresponding to a normal washing program of the washing machine. When the current power consumption exceeds the preset power consumption, the washing machine can be determined to have a fault, and the fault point can be a motor, a heating module and the like of the washing machine. The early warning can be carried out on the fault point, the washing machine is timely checked and maintained aiming at the fault point, and therefore the waste of electric quantity is avoided.

In an implementation manner of the embodiment of the present invention, optionally, determining a fault point of the washing machine, and performing an early warning to prompt maintenance based on the fault point includes: determining whether the no-load power consumption, the washing power consumption, the dehydration power consumption, and the heating power consumption respectively exceed corresponding preset no-load power consumption, preset washing power consumption, preset dehydration power consumption, and preset heating power consumption; if the no-load power consumption exceeds the preset no-load power consumption, determining that the pollution discharge device of the washing machine is in fault, and performing early warning based on the pollution discharge device to prompt the cleaning of the pollution discharge device; if the washing power consumption exceeds the preset washing power consumption or if the dehydration power consumption exceeds the preset dehydration power consumption, determining the motor fault of the washing machine, and performing early warning to prompt the maintenance of the motor based on the motor fault; and if the heating power consumption exceeds the preset heating power consumption, determining the fault of the heating module of the washing machine, and performing early warning based on the fault of the heating module to prompt the maintenance of the heating module.

The no-load power consumption can be the sum of the power consumption of water injection and drainage of the washing machine in one washing process and the power consumption of other non-washing, dewatering and heating links in the washing process. The washing power consumption may be a sum of power consumption of the main washing and the multiple rinsing performed by the washing machine using the rotation of the washing machine in one washing process. The dehydration power consumption may be the sum of power consumption of the washing machine for dehydration after the main washing and dehydration after each rinsing using the centrifugal action in one washing process. The heating power consumption can be the sum of the power consumption of the washing machine when the washing machine is heated by the heating module in one washing process. The determination method may be to measure the power consumption of each link, or may be to determine the power consumption by calculation according to parameters of each link.

In a specific implementation manner of the embodiment of the invention, if the no-load power consumption exceeds the preset no-load power consumption, it is determined that the drainage time is increased and the no-load power consumption is too high due to a fault of the drainage device of the washing machine, for example, a drain outlet or a pipeline is blocked. When the no-load power consumption exceeds the preset no-load power consumption, the early warning can be carried out to prompt the fault of the sewage discharging device, and the fault can be a sewage discharging port or a pipeline blockage, so that the sewage discharging device is required to be cleaned in time.

In another embodiment of the present invention, when the washing power consumption exceeds the preset washing power consumption, or when the dehydration power consumption exceeds the preset dehydration power consumption, a stalling condition may exist in the motor, which causes higher power consumption, and it may be determined that the motor of the washing machine has a fault.

In another specific implementation manner of the embodiment of the present invention, when the heating power consumption exceeds the preset heating power consumption, the heating module may have an inaccurate heating temperature, for example, when the washing temperature reaches the preset washing temperature, the heating module continues to heat, which may cause an excessively high temperature in the washing machine, resulting in poor performance of the laundry detergent, damage to the laundry, and resource waste. The heating module fault of the washing machine can be determined, and the heating module can be checked and maintained in time through early warning prompt.

On the basis of the foregoing embodiment, optionally, the method further includes: determining the accumulated power consumption of the washing machine in a preset historical period; and when the accumulated power consumption exceeds the preset accumulated power consumption, determining a recommended target washing mode, and giving an early warning to prompt washing according to the target washing mode based on the target washing mode.

Wherein the preset history period may be monthly, quarterly or yearly, and the accumulated power consumption may be determined by calculating a sum of total power consumptions of respective washings of the washing machine within the preset history period. The preset accumulated power consumption amount may be 1.1 to 1.3 times an average power consumption amount of the general household in a preset history period, which is obtained through data analysis. When the accumulated power consumption exceeds the preset accumulated power consumption, the power consumption of the washing machine of the user is too high, which indicates that the washing mode of the user is unreasonable, and the historical power consumption condition of the washing machine can be analyzed to recommend a proper washing mode to the user. The washing pattern may include a washing time period, a washing weight level, a washing program, a heating temperature, and the like.

The weight can be divided into different weight grades, such as 0-1 kg, 1-2 kg, 2-3 kg, etc. The power consumption of the same weight grade and the same washing program in different time periods is obtained from the plurality of power consumption data, when the power consumption is smaller than the set power consumption threshold value, the time period can be recommended to the user, and the user can be reminded of washing in the time period in an early warning mode so as to save electric energy. The set power consumption threshold may be power consumption matched with the same weight class and the same washing program, and may be obtained through testing, for example, may be 1.0 to 1.1 times of power consumption for washing clothes of the same weight class and the same washing program at the lowest peak of power consumption.

The power consumption data can be used for acquiring power consumption corresponding to different weight grades, the same time period and the same washing program, for example, the power consumption corresponding to the weight grades of 0-1 kg, 1-2 kg, 2-3 kg and the like in the target washing time period and the same washing program. The same washing procedure may refer to a washing procedure in which the set water consumption, the set washing time, and the set heating temperature are the same. The corresponding unit load power consumption amount is calculated from the power consumption amount, and normalization processing may be performed on the power consumption amount and the corresponding weight. When the unit load power consumption is smaller than the set unit load power consumption threshold, the weight grade corresponding to the unit load power consumption can be recommended to the user, and the user can be reminded of adopting the weight grade to wash in an early warning mode, so that the electric energy is saved. The set unit load power consumption threshold may be a unit load power consumption matched with the same washing program in the same time period, may be obtained through testing, and may be, for example, 1.0 to 1.1 times of the minimum value of the unit load power consumption under the same washing program at the lowest peak of the power consumption. The clothes washing machine has the advantages that the user can wash clothes by adopting the most power-saving weight grade, so that the electric energy and the cost are saved.

In an implementation manner of the embodiment of the present invention, optionally, determining a recommended target washing manner, and performing an early warning based on the target washing manner to prompt washing according to the target washing manner includes: acquiring the power consumption of washing clothes of a plurality of different washing programs according to the same weight grade in the same time period; and determining the washing program with the power consumption smaller than the second set power consumption threshold value as a recommended target washing program, and giving an early warning to prompt washing according to the target washing program based on the recommended target washing program.

The power consumption data may be obtained from a plurality of power consumption data, wherein the power consumption data may include power consumption data corresponding to different washing programs in the same weight class and the same time period, for example, the power consumption data may include power consumption data corresponding to target washing time periods and target washing weight classes. When the power consumption is smaller than the second set power consumption threshold, the washing program corresponding to the power consumption can be recommended to the user, and the user can be reminded of adopting the washing program to wash in an early warning mode, so that the electric energy is saved. The second set power consumption threshold may be power consumption of different washing programs matched with the same time period and the same weight class, and may be obtained through testing, for example, the second set power consumption threshold may be 1.0 to 1.1 times of the minimum value of the power consumption of each washing program under the same weight class at the lowest peak of power consumption. The user can know the most power-saving washing program, and the user can determine whether to adopt the target washing program to wash the clothes according to the dirt degree of the clothes, so that the electric energy is saved, and the cost is saved.

According to the technical scheme of the embodiment of the invention, the fault point of the washing machine is determined by determining the current power consumption of the washing machine for washing at this time, when the current power consumption exceeds the preset power consumption, and early warning is carried out based on the fault point to prompt maintenance, so that the problem of determining the fault point of the washing machine according to the power consumption of the washing machine is solved, and the effects of timely determining the fault point of the washing machine to prompt maintenance, reducing energy waste and saving family expenses are realized.
