Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order.

Example one

Fig. 1 is a schematic flow chart of a cleaning reminding method for a washing apparatus according to an embodiment of the present invention. In particular, the washing device may be a dishwasher or a bottle washing machine or the like. The method can be executed by a cleaning reminding device of the washing equipment, and the device can be a processor or an MCU (micro control unit) and the like arranged in the washing equipment; in the embodiment of the present application, a cleaning reminding device of a washing apparatus is taken as an execution main body for description, and the method specifically includes the following steps:

the filter member inside the washing apparatus is easily clogged with the contaminants, causing clogging of the circulation water path and re-contamination of the washing water filtered through the filter member by the contaminants attached to the filter member. And the user can not directly know the state of the filter component arranged in the washing equipment, so that the filter component in the washing equipment can not be cleaned in time. To solve this problem, the embodiment detects the operation state of the washing motor in real time when the washing motor of the washing device is in the working state; when the running state of the washing motor is detected to be in an overload state, judging that the washing motor is overloaded possibly due to the blockage of the filtering component, and controlling a heating device to heat the washing water in the inner cavity of the washing equipment; the temperature difference is obtained by synchronously detecting the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline where the washing motor is located, if the temperature difference meets the preset cleaning reminding condition within the preset time range, the blockage of the filter part is explained, the cleaning reminding information of the filter part is generated, and a user is reminded of cleaning the filter part inside the washing equipment.

S110, if a washing motor in the washing equipment is in a working state, acquiring running state information of the washing motor; the washing motor is used for conveying the washing water filtered by the filtering component to a spraying device of the washing equipment through a water conveying pipeline.

In practical application scenes, the washing equipment realizes the recycling of washing water by means of a filtering component and a circulating water path which are arranged inside the washing equipment so as to finish multiple washing work on articles to be washed. Specifically, as shown in fig. 2, the washing apparatus is a schematic structural diagram, and the washing apparatus may include an inner cavity 21, a spraying device 22, a filtering component 23, a washing motor 24, and a water conveying pipeline 25. The spray device 22 in the inner cavity 21 of the washing equipment sprays the washing water on the surface of the object to be cleaned placed in the inner cavity, and takes away the dirt on the surface of the object to be cleaned. The washing water and the dirty materials flowing down from the surface of the articles are accumulated at the bottom of the inner cavity 21 of the washing device, and the bottom of the inner cavity 21 of the washing device is provided with a filter part 23. The filth accumulated at the bottom of the inner chamber of the washing apparatus is filtered by the filter member 23, so that the filtered washing water is transferred again to the shower device 22 through the circulation water path. The circulating water path comprises a washing motor 24 and a water conveying pipeline 25, wherein the washing motor 24 is arranged on the water path between the water outlet of the filtering component 23 and the water conveying pipeline 25 connected with the water inlet of the spraying device 22, and circularly conveys the washing water filtered by the filtering component to the spraying device, so that the objects to be cleaned are circularly cleaned.

In the process that the washing motor conveys the washing water filtered by the filtering component to a spraying device of washing equipment through a water conveying pipeline, if the filtering component is blocked, the washing water entering the water conveying pipeline is enabled to carry small-particle foreign matters, so that the water outlet pressure of the water conveying pipeline is increased or the water conveying pipeline is slightly blocked, and the washing motor for conveying the washing water in the water conveying pipeline is overloaded. In order to know whether a filter part in the washing equipment is blocked by dirt substances, the running state information of the washing motor can be obtained by detecting the running state of the washing motor in real time when the washing motor of the washing equipment is in a working state, so that whether the washing motor is in an overload state is judged according to the obtained running state information of the washing motor, and the state of the filter part is determined. Alternatively, the operation state information of the washing motor may include information on the current operation power, operation current, or operation temperature of the washing motor.

S120, if the washing motor is determined to be in an overload state according to the running state information, controlling a heating device to heat the washing water in the inner cavity of the washing equipment, and synchronously detecting a first temperature value of the washing water in the inner cavity of the washing equipment and a second temperature value of the washing water in the water conveying pipeline.

After the running state information of the washing motor detected in real time is obtained, if the working state of the washing motor is determined to be in an overload state at any moment according to the running state information of the washing motor, the pressure increase of the water outlet of the water conveying pipeline or the slight blockage of the water conveying pipeline can be determined. However, the reasons for the increase of the pressure at the water outlet of the water conveying pipeline or the slight blockage of the water conveying pipeline may be the blockage of a filter part inside the washing equipment or the blockage of a spraying device. Specifically, because the heat conduction speed of water is extremely high, under the condition that the washing water is circularly conveyed by the washing motor in the water conveying pipeline, if the washing water is filtered by the filtering component and then can smoothly enter the water conveying pipeline, the heated washing water in the inner cavity of the washing equipment can quickly enter the water conveying pipeline, so that the difference between the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline is smaller; if the washing water is filtered by the filtering component and cannot smoothly enter the water conveying pipeline, namely the flow rate is reduced, most of the heated washing water in the inner cavity of the washing equipment is reserved in the inner cavity of the washing equipment, and a small part of the heated washing water enters the water conveying pipeline, so that the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline have larger difference. Therefore, whether the reason causing the working state of the washing motor to be in the overload state is the blockage of the filtering component is further determined, the washing water in the inner cavity of the washing equipment can be heated by controlling the heating device in the washing equipment when the washing motor is determined to be in the overload state according to the running state information, the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline are synchronously detected, namely, whether the filtering component in the washing equipment is blocked or not is determined by judging whether the heat conduction difference exists between the washing water in the inner cavity of the washing equipment and the washing water in the water conveying pipeline or not.

The operation state information for judging whether the operation state of the washing motor is in an overload state may include information on operation power, operation current, or operation temperature, etc. The washing motor in working state can be detected by measuring instruments such as power, current or temperature. In an implementation manner, if the operation state information of the washing motor obtained by real-time detection is the operation power, the specific process of determining whether the washing motor is in the overload state according to the operation state information may be: and if the running power of the washing motor exceeds a preset power threshold at any moment, determining that the working state of the washing motor is in an overload state. Specifically, the power threshold is set according to the overload power value of a washing motor in the washing equipment when the filtering component is blocked.

In another implementable manner, if the operation state information of the washing motor obtained by real-time detection is the working current, the specific process of determining whether the washing motor is in the overload state according to the operation state information may be: and if the working current of the washing motor exceeds a preset current threshold at any moment, determining that the working state of the washing motor is in an overload state. Specifically, the current threshold is set according to the overload current value of a washing motor in the washing equipment when the filtering component is blocked.

S130, if the temperature difference between the first temperature value and the second temperature value in a preset time range meets a preset cleaning reminding condition, cleaning reminding information of the filtering component is generated.

After the heating device is controlled to heat the washing water in the inner cavity of the washing equipment, as the washing water cannot smoothly enter the water conveying pipeline after being filtered by the filtering component, namely the flow rate is reduced, most of the heated washing water in the inner cavity of the washing equipment is stored in the inner cavity of the washing equipment, and a small part of the heated washing water enters the water conveying pipeline, so that the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline have larger difference.

In one implementation example, the cleaning reminding condition may be set according to a temperature difference between a first temperature value of the washing water in the inner cavity of the washing device and a second temperature value of the washing water in the water conveying pipeline when the filtering component of the washing device is blocked. When the temperature difference between a first temperature value of the washing water in the inner cavity of the washing equipment and a second temperature value of the washing water in the water conveying pipeline in a preset time range meets a preset cleaning reminding condition, determining that a filtering part in the washing equipment is blocked; at this time, the cleaning reminding device of the washing equipment generates cleaning reminding information of the filtering part of the washing equipment and reminds a user to clean the filtering part in the washing equipment.

In another embodiment, the cleaning reminding condition may be set according to a relationship between the heat energy provided by the heating device of the washing equipment and the temperature difference between the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline. Specifically, due to the law of conservation of energy, when the heating device inside the washing apparatus heats the washing water to provide the heat energy Q, the temperature of the washing water gradually rises after receiving the heat energy Q. And because the washing water can enter the water conveying pipeline from the inner cavity of the washing equipment only by being filtered by the filtering component, wherein the heat conduction process is involved, the washing water is conducted according to the temperature difference delta T between the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline and the area of a heat conduction substance (namely the filtering component)

The heat energy Q provided by the heating device to heat the washing water can be calculated according to the thickness l and the heat conduction coefficient lambda of the washing water. Due to impurities and heat energy conversion loss in the washing water, the actually received heat energy when the washing water is heated is eta Q, wherein eta is a heat loss parameter set according to the components of the washing water and the heat energy conversion loss.

In detail, if the washing water is filtered by the filtering component and then smoothly enters the water conveying pipeline, the washing water heated in the inner cavity of the washing equipment can quickly enter the water conveying pipeline for heat transfer, so that the first temperature value and the water conveying of the washing water in the inner cavity of the washing equipment are enabledThe difference of the second temperature value of the washing water in the water pipeline is small, so that the conservation of eta Q between the heat energy in the washing water heat conduction and the actually received heat energy in the washing water temperature rise is maintained, namely the requirement of meeting

If the washing water is filtered by the filtering component and cannot smoothly enter the water conveying pipeline, namely the flow rate is reduced, most of the heated washing water in the inner cavity of the washing equipment is stored in the inner cavity of the washing equipment for heat storage and temperature rise, only a small part of the heated washing water enters the water conveying pipeline for heat transfer, so that the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline have larger difference, the heat energy during the heat transfer of the washing water is larger than the actually received heat energy during the temperature rise of the washing water and is eta Q, namely the requirement that the actually received heat energy during the heat transfer of the washing water is greater than the actually received heat energy during the temperature rise of the washing water is met

Therefore, the cleaning reminding conditions can be preset as follows:

And because the heat conduction process of the water is nonlinear, the special condition that the heat energy during the heat conduction of the washing water and the heat energy actually received when the temperature of the washing water is raised are not conserved eta Q may exist in a period of time when the heating device of the washing equipment just starts to heat the washing water in the inner cavity of the washing equipment, so that the preset time range is set according to the consumed time of the special condition. If the temperature difference between the first temperature value and the second temperature value in a preset time range meets a preset cleaning reminding condition, determining that a filtering part in the washing equipment is blocked; at this time, the cleaning reminding device of the washing equipment generates cleaning reminding information of the filtering part of the washing equipment and reminds a user to clean the filtering part in the washing equipment.

When the temperature difference between the first temperature value and the second temperature value meets the preset cleaning reminding condition within the preset time range, the cleaning reminding device of the washing equipment generates cleaning reminding information of the filter component of the washing equipment, and in order to timely and effectively enable the client to receive the generated cleaning reminding information of the filter component of the washing equipment, the cleaning reminding information of the filter component of the washing equipment can comprise reminding information of a cleaning reminding indicator lamp of the filter component arranged in a panel of the washing equipment or cleaning reminding information of the filter component sent to a user terminal in communication connection with the washing equipment, and the like.

In an implementation example, when the cleaning reminding information of the filter component of the washing device is reminding information of a cleaning reminding indicator lamp of the filter component arranged in a panel of the washing device, if a temperature difference between the first temperature value and the second temperature value within a preset time range meets a preset cleaning reminding condition, a specific process of generating the cleaning reminding information of the filter component may be: if the temperature difference between the first temperature value and the second temperature value within the preset time range meets the preset cleaning reminding condition, a flicker instruction of a cleaning reminding indicator of the filter component is generated, so that the cleaning reminding indicator of the filter component arranged in a panel outside the washing equipment flickers, and the cleaning reminding information of the filter component, which can be intuitively received by a user, of the washing equipment is obtained.

In another implementation example, when the cleaning reminding information of the filter component of the washing device is the cleaning reminding information sent to the filter component of the user terminal in communication connection with the washing device, after the cleaning reminding information of the filter component is generated, the cleaning reminding information of the filter component needs to be sent to the corresponding user terminal, and the specific steps include steps 11 to 13:

step 11, if a user terminal in communication connection with the washing equipment is detected to exist at present, sending the generated cleaning reminding information of the filtering component to the user terminal;

when the temperature difference between the first temperature value of the washing water in the inner cavity of the washing equipment and the second temperature value of the washing water in the water conveying pipeline is detected to meet the preset cleaning reminding condition within the preset time range, after the cleaning reminding information of the filter part is generated, the cleaning reminding information of the filter part needs to be sent to the corresponding user terminal. Because the user terminal which is in communication connection with the washing equipment at present may be the user who is logging in the client corresponding to the washing equipment through the user terminal to inquire the information of the washing equipment, in order to enable the user to check the cleaning reminding information of the filtering component in time, the user terminal which is in communication connection with the washing equipment at present can be used as a target terminal to send the information. Specifically, after the cleaning reminding information of the filtering component is generated, a cleaning reminding device of the washing equipment detects whether a user terminal in communication connection with the washing equipment exists at present; and if the user terminal in communication connection with the washing equipment exists currently, the cleaning reminding device of the washing equipment sends the generated cleaning reminding information of the filtering component to the user terminal in communication connection with the washing equipment currently. Optionally, after receiving the cleaning reminding information of the filter component, the user terminal may display the cleaning reminding information of the filter component to the user in a form of push notification of a client corresponding to the washing device, so as to remind the user of cleaning the filter component inside the washing device in time.

Step 12, if detecting that no user terminal in communication connection with the washing equipment exists currently, screening out historical login terminals meeting notification conditions according to the connection times and connection time corresponding to each historical login terminal in the historical login record table; the history login record table is used for recording the connection times, connection time and communication addresses of the history login terminal in communication connection with the washing equipment;

after the cleaning reminding information of the filtering component is generated, when the cleaning reminding device of the washing equipment detects that no user terminal in communication connection with the washing equipment exists at present, the history login terminal which meets the notification condition can be screened out according to the connection times and the connection time corresponding to each history login terminal in the history login record table and used as a target terminal for receiving the cleaning reminding information of the filtering component. Specifically, since a user who frequently uses the washing machine may frequently log in the client corresponding to the washing machine through the user terminal to check the state information of the washing machine, the historical log-in terminal of the user who frequently uses the washing machine can be determined according to the connection times and the connection time corresponding to each historical log-in terminal in the historical log-in record table. Alternatively, the preset notification condition may be that the latest connection time is limited within a preset time range and the historical connection times exceed a preset threshold value, so that the historical login terminal screened out by the notification condition is limited to be the historical login terminal which has logged in recently and is connected with the washing equipment for a long time.

And step 13, establishing communication connection between the washing equipment and the screened historical login terminals based on the communication addresses of the screened historical login terminals, and sending the generated cleaning reminding information of the filtering component to the screened historical login terminals.

Since the history log table is used for recording the connection times, connection time and communication addresses of the history log terminals which are in communication connection with the washing equipment, the communication addresses corresponding to the screened history log terminals can be obtained through the history log table. And the cleaning reminding device of the washing equipment actively performs communication connection with the screened historical login terminal according to the obtained communication address, and sends the generated cleaning reminding information of the filtering component to the user terminal which is in communication connection with the washing equipment at present. Optionally, after receiving the cleaning reminding information of the filter component, the user terminal may display the cleaning reminding information of the filter component to the user in a form of push notification of a client corresponding to the washing device, so as to remind the user of cleaning the filter component inside the washing device in time.

In one embodiment, the cleaning reminding method of the washing device may further include: when the washing equipment finishes one washing, adding one to the recorded washing history times; and if the updated washing history times are larger than or equal to a preset threshold value, clearing the updated washing history times, generating cleaning reminding information of the filtering component and sending the cleaning reminding information to a client end in communication connection with the washing equipment.

In particular, since the washing device inevitably causes the filter member to be clogged after a plurality of washing operations are performed, whether the filter member inside the washing device needs to be cleaned can be simply determined according to the number of times the washing operation is performed by the washing device. The cleaning reminding device of the washing equipment can count the washing history times once when the washing equipment completes a washing task, and optionally, the counting method of the washing history times can be that one is added to the recorded washing history times when the washing equipment completes one washing. Updating the counted washing history times to washing history times recorded by a cleaning reminding device of the washing equipment, and then judging whether the updated washing history times are equal to or larger than a preset threshold value or not; if the updated washing history times are larger than or equal to the preset threshold value, the fact that the state of the filtering part of the washing equipment is possibly in a blocking state and needs to be cleaned is indicated, the updated washing history times are cleared so that the filtering part can be cleaned and then the washing times of the washing equipment are counted again, cleaning reminding information of the filtering part is generated and sent to a client end in communication connection with the washing equipment, and therefore a user is reminded of cleaning the filtering part in the washing equipment in time. In order to timely and effectively enable the client to receive the generated cleaning reminding information of the filtering part of the washing equipment, the cleaning reminding information of the filtering part of the washing equipment can comprise reminding information of a cleaning reminding indicator lamp of the filtering part arranged in a panel of the washing equipment or cleaning reminding information of the filtering part sent to a user terminal in communication connection with the washing equipment.

In one embodiment, after generating the cleaning reminding information of the filter component if the temperature difference between the first temperature value and the second temperature value within the preset time range satisfies the preset cleaning reminding condition, the method further includes: after the washing equipment completes the current washing task, locking the washing function of the washing equipment; detecting an installation state of the filter member; and if the filter component is detected to be detached, unlocking the washing function of the washing equipment.

Specifically, in order to prevent a user from forcibly starting the washing equipment to continuously wash the articles to be washed regardless of the cleaning reminding information of the filter component, the cleaning reminding device of the washing equipment can lock the washing function of the washing equipment after the washing equipment completes the current washing task; the cleaning reminding device of the washing equipment also detects the installation state of the filter component in real time; and if the filter component is detected to be detached, the locking of the washing function of the washing equipment is released, so that the user can use the washing equipment again only by cleaning the filter component inside after receiving the cleaning reminding information of the filter component.

In one embodiment, to ensure the cleaning strength of the washing device, the cleaning reminding device of the washing device prolongs the washing time of the washing device when the temperature difference between the first temperature value of the washing water in the inner cavity of the washing device and the second temperature value of the washing water in the water conveying pipeline in the preset time range meets the preset cleaning reminding condition. Specifically, when the washing device detects that the temperature difference between the first temperature value and the second temperature value meets the preset cleaning reminding condition when the washing device performs the washing operation, it is indicated that the filtering component may be blocked at the moment to reduce the cleaning force of the washing device, so that the cleaning reminding device of the washing device prolongs the washing time of the washing task currently performed by the washing device, and the cleaning force of the washing device is ensured.

In one embodiment, the cleaning waiting time of the filter element is too long due to the fact that the process from the time when the user receives the cleaning reminding information of the filter element to the time when the user cleans the filter element is too long. In order to solve the problem, a cleaning spray head connected with the water conveying pipeline can be arranged at the top of the inner cavity of the washing equipment; if the temperature difference between the first temperature value and the second temperature value within the preset time range meets the preset cleaning reminding condition, then after the cleaning reminding information of the filtering component is generated, the method further comprises the following steps: and controlling the cleaning spray head to move to a preset angle, and starting the cleaning spray head to clean the filtering component.
