Description

Technical Field

[0001] The present application belongs to the field of electrical appliance technology, and specifically relates to a washing fault identification method, device, equipment and storage medium. Background Art

[0002] With the continuous improvement of production technology and the continuous growth of user demand, users' requirements for clothing processing equipment are also getting higher and higher.

[0003] When executing the washing water inlet stage of the laundry processing program, the existing laundry processing device usually detects the water level in the drum through a water level sensor, and closes the water inlet valve after the water level in the drum reaches a preset height threshold, so that the laundry processing device stops taking in water and starts washing the clothes; the existing laundry processing device usually adopts an upper drainage method, that is, the drain port is located at the upper part of the washing machine. Due to the height difference between the drain port and the inner drum of the washing machine, the water in the inner drum cannot flow out through the drain port without external force. When the drainage time set by the program is reached, the laundry processing device turns on the drainage pump in the drainage pipe to discharge the water in the inner drum under the action of the drainage pump. However, if the drainage pipe is not installed completely according to the design requirements, the height difference between the drain port and the inner drum of the washing machine is insufficient, and a sufficiently large pressure difference cannot be formed, or the drainage hose is pushed too deep into the riser and an air gap cannot be formed, resulting in a vacuum or siphon phenomenon in the pipe when the water level in the inner drum is high during the washing process, and the washing water is pumped out of the drum, so that the drainage is no longer controlled by the drainage pump, resulting in a drop in the water level in the drum.

[0004] The existing water level detection logic, after detecting that the water level in the drum has not reached the preset water level, will control the clothing processing equipment to open the water inlet valve, causing the clothing processing equipment to have a "water intake and water discharge" fault, resulting in a waste of water resources and a decrease in washing effect.

[0047] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0050] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0051] With the continuous improvement of production technology and the continuous growth of user demand, users' requirements for clothing processing equipment are also getting higher and higher.

[0052] When executing the washing water inlet stage of the laundry processing program, the existing laundry processing device usually detects the water level in the drum through a water level sensor, and closes the water inlet valve after the water level in the drum reaches a preset height threshold, so that the laundry processing device stops taking in water and starts washing the clothes; the existing laundry processing device usually adopts an upper drainage method, that is, the drain port is located at the upper part of the washing machine. Due to the height difference between the drain port and the inner drum of the washing machine, the water in the inner drum cannot flow out through the drain port without external force. When the drainage time set by the program is reached, the laundry processing device turns on the drainage pump in the drainage pipe to discharge the water in the inner drum under the action of the drainage pump. However, if the drainage pipe is not installed completely according to the design requirements, the height difference between the drain port and the inner drum of the washing machine is insufficient, and a sufficiently large pressure difference cannot be formed, or the drainage hose is pushed too deep into the riser and an air gap cannot be formed, resulting in a vacuum or siphon phenomenon in the pipe when the water level in the inner drum is high during the washing process, and the washing water is pumped out of the drum, so that the drainage is no longer controlled by the drainage pump, resulting in a drop in the water level in the drum.

[0053] The existing water level detection logic, after detecting that the water level in the drum has not reached the preset water level, will control the clothing processing equipment to open the water inlet valve, causing the clothing processing equipment to have a "water intake and water discharge" fault, resulting in a waste of water resources and a decrease in washing effect. The existing clothing processing equipment fault detection logic is unable to effectively identify this fault, causing great inconvenience to users.

[0054] In response to the above problems, the present application proposes the following technical concept: when the clothing processing device executes the washing stage of the clothing processing program, the total water intake of the clothing processing device in the washing stage is obtained in real time, and according to the changes in the total water intake, it is judged whether the clothing processing device has a water intake and drainage failure, so as to promptly and accurately identify the above-mentioned "water intake and drainage" failure without adding additional detection hardware, so that the failure can be handled in a timely manner, thereby improving the user experience.

[0055] Figure 1 Schematic diagram of the washing fault identification method provided in the embodiment of the present application Figure 1 ;like Figure 1 As shown, the washing fault identification method provided by the embodiment of the present application includes:

[0056] S101: When starting the washing phase of a laundry treatment program, obtaining the water intake of the laundry treatment device at preset time intervals, and recording the water intake at different obtaining moments.

[0057] Specifically, when the clothing processing device executes the washing stage of the clothing processing program, the fault identification device reads the operating information of the clothing processing device at preset time intervals, obtains the water intake of the clothing processing device based on the operating information, and stores the water intake at different acquisition times in a storage device; the specific method for obtaining the water intake of the clothing processing device based on the operating information may, for example, be to obtain the opening time period of the water inlet valve reported by the clothing processing device, and calculate the total amount of water passing through the water inlet valve up to each acquisition time as the water intake at each acquisition time based on the rated water inlet rate of the water inlet valve and the opening time period.

[0058] S102: If it is determined that there is no abnormality in the washing stage according to the current water intake, then continue to obtain a new water intake until the first water intake when the clothes have a maximum water absorption time is obtained.

[0059] The maximum water absorption time of the laundry is used to indicate the time required for the laundry to absorb water to a saturated state.

[0060] It can be understood that if the clothing processing equipment has a fault of "taking in water and discharging water at the same time", the water intake during the washing stage will be higher than the water intake during the washing stage under normal operating conditions. Therefore, the maximum water intake threshold for the washing stage can be set in advance. The maximum water intake threshold is used to indicate the maximum water intake required for the washing stage, for example, it can be 60L; if the water consumption corresponding to a certain acquisition moment exceeds the maximum water intake threshold, that is, the current water intake is much higher than the water intake during the washing stage under normal operating conditions, it may be caused by a large amount of water discharged from the clothing processing equipment. At this time, it can be judged that there is an abnormality in the washing stage.

[0061] If the abnormality in the washing stage is not determined based on the current water intake alone, one possible scenario is that the clothing processing equipment has not had the above-mentioned fault, or it may be that the clothing processing equipment has had the above-mentioned fault, but the water discharge volume is small. Therefore, the possibility of a fault cannot be completely ruled out based on the current water intake alone. You can continue to obtain a new water intake and continue to judge whether there is an abnormality in the washing stage based on the new water intake.

[0062] Specifically, the fault identification device compares the water intake value corresponding to the current acquisition moment with the preset maximum water intake threshold. If the water intake value corresponding to the current acquisition moment is less than the preset maximum water intake threshold, it is preliminarily determined that there is no abnormality in the washing stage; the fault identification device continues to obtain new water intake until the first water intake when the clothes have the maximum water absorption time is obtained.

[0063] S103: judging whether there is any abnormality in the washing stage according to the first water intake amount.

[0064] It is understandable that after the clothes enter the washing stage, the water level in the drum will drop because the clothes may absorb some of the washing water. When the water level in the drum is lower than the preset washing water level, the clothes processing equipment will turn on the intelligent water replenishment function. At this time, the water intake of the clothes processing equipment will increase to a certain extent. The increase in water intake caused by this process is a normal phenomenon, not a fault phenomenon. To avoid misjudgment of this phenomenon, the first water intake when the washing time reaches the maximum water absorption time of the clothes can be obtained to exclude the water intake caused by intelligent water replenishment when judging the fault.

[0065] Specifically, the fault identification device determines whether there is an abnormality in the washing stage according to a preset algorithm based on the first water intake volume and the water consumption at each acquisition moment obtained subsequently; the preset algorithm may, for example, be a numerical comparison of the water consumption at each acquisition moment with the first water intake volume, and determine whether there is an abnormality in the washing stage according to the comparison result; it may also be a method of establishing a water consumption change curve based on the water consumption at each acquisition moment, and determining whether there is an abnormality in the washing stage according to the characteristics of the curve; the embodiment of the present application does not limit the specific method for determining a fault.

[0066] The washing fault identification method provided in the embodiment of the present application obtains the total water intake of the clothing processing device at each preset time in the washing stage, and judges whether the clothing processing device has a water intake and drainage fault according to the numerical value and change of the total water intake and the first water intake when the washing time reaches the maximum water absorption time of the clothes. Under the premise of low detection cost, the "water intake and drainage" fault is timely and accurately identified, thereby reducing the fault detection cost, allowing the fault to be handled in time, and improving user satisfaction.

[0067] Figure 2 Schematic diagram of the washing fault identification method provided in the embodiment of the present application Figure 2 ;like Figure 2 As shown, the washing fault identification method provided by the embodiment of the present application includes:

[0068] S201: When executing the water intake phase of the laundry treatment program, the water level in the drum is obtained according to a preset cycle.

[0069] Specifically, when executing the water intake stage of the laundry processing program, the fault identification device obtains the water level in the drum according to a preset cycle through a liquid level sensor provided in the laundry processing device.

[0070] S202: judging whether the water inlet stage is finished according to the water level in the cylinder.

[0071] Specifically, the fault identification device compares the acquired water level in the drum with the preset washing water level in numerical value, and determines whether the water inlet stage is completed according to the comparison result.

[0072] S203: When the water inlet stage ends, the water inlet duration is obtained, and whether there is an abnormality in the water inlet stage is determined according to the water inlet duration.

[0073] Specifically, if the water level in the drum is greater than or equal to the preset washing water level, it is determined that the water inlet stage is over. When the water inlet stage is over, the fault identification device obtains the time from the start time of the water inlet stage to the current time as the water inlet time, and determines whether there is an abnormality in the water inlet stage based on the water inlet time.

[0074] It is understandable that when executing the water inlet stage of the clothing treatment program, the clothing treatment equipment usually controls the water inlet valve on the water inlet pipe connected to the water source to open. At this time, there is a pressure difference between the water source and the water inlet pipe, and the water flows from the water source through the water inlet pipe into the barrel of the clothing treatment equipment under the action of pressure; if the water pressure in the user's home is low, the faucet is not fully opened, or the connection between the water inlet pipe and the faucet is not tight enough, resulting in a smaller pressure difference between the water source and the water inlet pipe, the water inlet rate will decrease and the water inlet time will be longer; if the clothing treatment equipment takes in water and drains water at the same time during the water inlet stage, the water inlet time will also be prolonged. The above situations can all be regarded as abnormalities in the water inlet stage.

[0075] When the water inlet rate is lower than the normal range, the method of calculating the water inlet volume based on the rated rate of the water inlet valve and the opening time of the water inlet valve will have a large error, affecting the accuracy of fault identification; therefore, it is possible to judge whether there is an abnormality in the water inlet stage based on the water inlet time, so that users and maintenance personnel can discover potential water inlet faults as early as possible and improve the accuracy of subsequent drainage fault identification.

[0076] Optionally, the specific method steps for judging whether there is an abnormality in the water inlet stage according to the water inlet duration may be, for example:

[0077] Step 1: Obtain the rated water inlet volume of the washing program and the rated water inlet rate of the clothing processing equipment.

[0078] Step 2: Obtaining an actual water inflow rate of the clothing processing device according to the rated water inflow volume and the water inflow time.

[0079] Step 3: If the actual water inlet rate is less than the rated water inlet rate, then obtain the difference between the rated water inlet rate and the actual water inlet rate.

[0080] Step 4: If the difference is greater than a preset difference, it is determined that an abnormality exists in the water inlet stage.

[0081] S204: If there is an abnormality in the water inlet stage, a water inlet abnormality alarm is sent to the user.

[0082] Specifically, if the fault identification device determines that there is an abnormality in the water inlet stage, it controls the clothing processing equipment to send an abnormal water inlet alarm to the user. The alarm may be, for example, a message push to the user terminal or a specific fault code displayed by a display device.

[0083] S205: If there is no abnormality in the water inlet stage, when executing the washing stage of the clothing processing program, the water inlet amount of the clothing processing device is obtained at preset time intervals, and the water inlet amount at different acquisition times is recorded.

[0084] The implementation method of step S205 is similar to the implementation method of step S101, and will not be described in detail in this embodiment.

[0085] S206: Obtain the weight and material type of the laundry in the drum.

[0086] It can be understood that the water absorption time of the clothes is related to the water absorption amount and water absorption rate of the clothes, and the main factors affecting the water absorption amount and water absorption rate of the clothes include the weight of the clothes and the material of the clothes. Therefore, the weight of the clothes to be washed in the drum and the type of clothes material can be obtained to determine the maximum water absorption time of the clothes to be washed in the drum accordingly.

[0087] Specifically, the laundry processing device obtains the weight of the laundry in the drum through the gravity sensor, and obtains the type of clothing material of the laundry by reading the clothing material type option manually selected by the user.

[0088] S207: According to the clothing material type, a correspondence between the maximum water absorption time of clothing associated with the clothing material type is obtained.

[0089] Among them, different clothing material types correspond to different clothing maximum water absorption time correspondences, and the clothing maximum water absorption time correspondence is used to indicate the correspondence between different clothing weights and clothing maximum water absorption time

[0090] Specifically, the storage device pre-stores the correspondence between the maximum water absorption time of different clothes corresponding to different clothing material types, and the clothing processing device obtains the correspondence between the maximum water absorption time of clothes associated with the clothing material type from the storage device according to the clothing material type.

[0091] S208: Obtaining the maximum water absorption time of the clothes according to the corresponding relationship and the weight of the clothes.

[0092] Specifically, the laundry processing device obtains the maximum water absorption time of the laundry corresponding to the laundry weight from the storage device according to the corresponding relationship and the laundry weight.

[0093] S209: If it is determined that there is no abnormality in the washing stage according to the current water intake, then continue to obtain a new water intake until the first water intake when the clothes have a maximum water absorption time is obtained.

[0094] The maximum water absorption time of the laundry is used to indicate the time required for the laundry to absorb water to a saturated state.

[0095] The implementation of step S209 is similar to that of step S102, and will not be described in detail in this embodiment.

[0096] S210: Continue to obtain N water intake volumes at N moments according to preset time intervals.

[0097] Wherein, N is a positive integer.

[0098] S211: Determine a change trend of the water inlet volume of the clothes processing device according to the relative magnitudes of the first water inlet volume and the N water inlet volumes at the N moments.

[0099] Specifically, the fault identification device compares the relative sizes of the first water intake volume and the N water intake volumes at the N moments, and determines the water intake volume change trend of the clothing processing equipment according to the relative size relationship of the values. For example, if the values ​​of the first water intake volume and the N water intake volumes at the N moments are equal, it can be determined that the water intake volume change trend is that the water intake volume remains unchanged after the clothes have completed absorbing water; if the values ​​of the first water intake volume and the N water intake volumes at the N moments increase with the passage of time, it can be determined that the water intake volume change trend is that the water intake volume continues to increase after the clothes have completed absorbing water.

[0100] S212: judging whether there is any abnormality in the washing stage according to the change trend of the water intake amount of the clothes processing device.

[0101] It is understandable that, under normal circumstances, after the clothes have fully absorbed water and the water level in the drum has reached the preset water level, the clothes processing equipment will not take in water again during the washing stage. Therefore, the trend of the water intake under normal circumstances is that the water intake remains unchanged after the clothes have completed absorbing water; if the clothes processing equipment has a fault of taking in water and discharging water at the same time, the trend of the water intake is that the water intake continues to increase after the clothes have completed absorbing water, and the increased water intake reaches a certain amount.

[0102] Optionally, according to the change trend of the water intake of the clothes processing device, a specific method for judging whether there is an abnormality in the washing stage may be, for example:

[0103] If the water inlet change trend is that the water inlet continues to increase, and the difference between the Nth water inlet and the first water inlet is greater than a preset difference, it is determined that there is an abnormality in the washing stage.

[0104] Specifically, if the fault identification device determines that the trend of the water intake change is a continuous increase in the water intake, then the difference between the Nth water intake and the first water intake is obtained, and the numerical value is compared with the preset difference. If the difference is greater than the preset difference, it is determined that there is an abnormality in the washing stage.

[0105] S213: If there is an abnormality in the washing stage, a drainage abnormality alarm is sent to the user, and the clothes processing device is controlled to stop water intake.

[0106] Specifically, if the fault identification device determines that there is an abnormality in the washing stage, it controls the clothing processing equipment to send a drainage abnormality alarm to the user. The alarm may be, for example, a message push on the user terminal or a specific fault code displayed on a display device, and controls the clothing processing equipment to stop taking in water to avoid possible losses caused by the drainage abnormality.

[0107] The washing fault identification method provided in the embodiment of the present application achieves accurate identification of specific water inlet faults and drainage faults at low cost and with short delay time by acquiring the operating information reported by the clothing processing equipment in the water inlet stage and the washing stage respectively, and sends a corresponding abnormal alarm to the user after the fault is identified, so that the above-mentioned fault can be discovered and handled in time, thereby improving the user experience.
