Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing machines, in particular, relates to a control method of a washing machine and the washing machine. BACKGROUND

[0002] With the continuous improvement of the level of science and technology, more and more washing machines appear in people's life, and the protection of clothes in the washing process is also improved. The appearance of the clothes treatment agent feeding device greatly facilitates people's life. However, with the change of the washing agent in the prior art, the siphon cap is prone to looseness with the increase of the washing cycle, resulting in improper installation. When using viscous washing agent or softener, long-term accumulation can cause siphon pipe blockage, which cannot normally siphon water. Often, the water storage capacity of the water storage tank exceeds the standard, or the washing machine appears overflow foam phenomenon.

[0003] A Chinese patent with application number CN207017037U discloses a washing agent box assembly and a washing machine comprising the same, which comprises a feeding chamber for feeding washing agent and a feeding chamber box cover connected with the feeding chamber. A siphon pipe is formed in the feeding chamber, and a siphon cap corresponding to the siphon pipe is formed on the feeding chamber box cover. The siphon cap can be connected with the siphon pipe in a manner of accommodating the siphon pipe. In the assembled state, the feeding chamber box is connected to the feeding chamber, so that the position of the siphon cap relative to the siphon pipe is fixed. Although the device effectively solves the problem of unstable connection between the siphon pipe and the siphon cap, when the siphon cap position changes and the siphon fails, the position of the siphon cap cannot be detected, and the user cannot be warned. When washing clothes, it is easy to cause the washing agent to be unable to be fed or the siphon pipe to be blocked, which cannot normally siphon water or cause the water storage capacity of the water storage tank to exceed the standard, thereby reducing the treatment effect on clothes and the feeding performance of the washing agent box, and the washing machine appears overflow foam phenomenon.

[0004] Therefore, the present application is proposed. SUMMARY

[0042] As Figures 1 to 3 shown, the control method of the washing machine comprises the following steps,

[0043] S1, the washing machine starts running;

[0044] S2, detecting the relative position between the siphon cap and the siphon pipe of the detergent box;

[0045] S3, judging whether the detected position exceeds the preset position range, if yes, determining that the detergent box siphon is faulty.

[0046] The present application detects the relative position between the siphon cap and the siphon pipe of the detergent box after the washing machine runs, and determines that the detergent box siphon is faulty if it exceeds the preset range according to the position range set in the washing machine control system. The corresponding fault data is displayed on the washing machine, which timely reminds the user when the position of the siphon cap relative to the siphon pipe changes, avoids the phenomenon of insufficient siphoning or siphon pipe blockage, ensures the normal operation of the washing machine, at the same time, achieves the effect of fault warning, improves the washing effect of the washing machine, and improves the user experience.

[0047] Further, in the step S2, the relative position between the siphon cap and the siphon pipe of the detergent box is detected by detecting the distance L of the siphon cap relative to the siphon pipe.

[0048] The present application can detect the relative position of the siphon cap and the siphon pipe by displacement sensor, laser sensor, infrared sensor and other sensors, so as to timely remind the user of siphon failure when the washing machine runs, reduce the phenomenon of incomplete siphoning of the washing machine, improve the clothes processing effect, and increase the user experience.

[0049] Further, in the step S3, it is judged whether the detected distance L is greater than the preset distance L1, if yes, it is determined that the detergent box siphon is faulty, if not, it is determined that the washing machine is running normally.

[0050] The related position range L1 set by the application includes the relative position parameter between the siphon cap and the siphon pipe when the washing machine is dispensing detergent, and also includes the relative position parameter between the siphon cap and the siphon pipe when the washing machine is not dispensing detergent. The washing machine in different stages is compared with the corresponding set relative position range.

[0051] As Figure 2 shown, one embodiment is that, in the step S3, if it is determined that the detergent box siphon fails, the following step is further included,

[0052] S4, issuing a siphon failure warning.

[0053] In the application, when the washing machine detects a fault signal, the local control system obtains a pre-warning fault signal, and then issues an alarm to remind the user to timely eliminate the fault, realizes real-time monitoring of the running state of the washing machine, prevents the user from not receiving the fault information in time, reduces the washing efficiency, realizes the intelligentization of the equipment, increases the use experience of the user, and improves the work efficiency.

[0054] In the step S4, a solution to the siphon failure is obtained, and a siphon failure warning and a solution prompt are issued.

[0055] Specifically, the database of the local system is provided with a plurality of fault types, and each fault type corresponds to different position information, and also includes a display identifier of each fault type. When the database receives a fault signal, the position transmitted by the signal is compared and analyzed with the types set in the database to determine the fault type, select the display identifier corresponding to the fault type, and display it on the washing machine in the form of PCB display to remind the user of the current running state of the equipment.

[0056] Preferably, the siphon cap failure solution is manual reset.

[0057] Further, after the step S4, the following step is further included,

[0058] S5, after a preset time t, step S2 is performed.

[0059] The siphon failure time t1 is compared with the preset time t to determine whether the siphon failure time t of the detergent box is greater than or equal to the preset time t1, if yes, step S2 is performed.

[0060] The siphon failure time t1 is compared with the preset time t to determine whether the siphon failure time t of the detergent box is greater than or equal to the preset time t1, if no, step S4 is performed.

[0061] The preset time t is 1min≤t≤3min.

[0062] Preferably, the preset time t is 2 min.

[0063] The present application can compare the siphon failure time t1 of the detergent box with the preset time t, so that the user can detect the relative position of the siphon cap and the siphon pipe on the detergent box again after the failure is solved through the prompt, avoid incomplete solution by the user, reduce the laundry treatment effect, and increase the user experience.

[0064] Preferably, the failure state displayed on the washing machine is E0.

[0065] The present application can make the user connect the failure position or the failure cause by displaying the failure state E0 on the device, and further process the failure by referring to the solution in the voice prompt or the manual; the reminding mode includes voice, indicator light, photoelectric, and other modes. After the failure is prompted, the device can also be provided with a determination button for indicating that the failure processing is completed, if so, the device continues to run, and the position information L of the siphon cap is detected again, and the system compares the detected position L with the system set position parameter L1, and when it is within the range, the washing machine continues to run normally.

[0066] Preferably, the prompt solution mode is scrolling display on the washing machine and / or voice prompt.

[0067] As shown in Figure 3 Another embodiment is that, in the step S3, if it is determined that the detergent box siphon fails, the following steps are further included,

[0068] S4, sending the siphon failure warning to the user's mobile phone APP by using the cloud server.

[0069] In the present application, after the failure alarm state is displayed on the washing machine, the control system on the washing machine uploads the alarm state and data to the cloud server and sends them to the mobile phone APP, so that the user can observe the running state of the washing machine even when he / she is not near the washing machine, the washing machine is intelligentized, the user's use experience is increased, and the work efficiency is improved.

[0070] In the step S4, after it is determined that the detergent box siphon fails, the cloud server analyzes and selects a specific processing solution for the siphon failure, and sends it to the mobile phone APP.

[0071] Specifically, a plurality of failure processing solutions are set in the cloud server, after being uploaded to the cloud server, the cloud server analyzes the data and extracts the processing solution for the corresponding failure in the cloud server, sends the failure alarm data to the mobile phone APP, and sends the corresponding solution, so as to prewarn or remind the user to solve in time according to the corresponding solution, increase the user's experience, and improve the washing efficiency.

[0072] The cloud server of the laundry machine can also collect the use and operation habits of the user, and when the user takes too long to handle a fault, the cloud server can record the corresponding fault, and at the same time, can provide a relatively simple processing scheme next time the same fault occurs, and can generate corresponding data, and can provide a timely warning and a corresponding solution when a misoperation is made, and can provide a monitoring scheme for the running state of an online device.

[0073] Preferably, the solution to the ejection of the siphon cap is manual reset.

[0074] Further, after the step S4, the following steps are further included,

[0075] S5, after a preset time t, step S2 is performed.

[0076] The siphon fault time t1 is compared with the preset time t to determine whether the siphon fault time t of the detergent box is greater than or equal to the preset time t1, and if not, step S4 is performed.

[0077] The preset time t is 1min≤t≤3min.

[0078] Preferably, the preset time t is 2min.

[0079] The present application can also determine whether the user operates according to the corresponding prompt by selecting the corresponding solution displayed on the mobile phone APP, prevent the user from detecting the siphon cap again after the operation is completed, determine that the siphon cap has been reset, improve the practicability and intelligence of the laundry machine, and increase the experience of the user.

[0080] After the manual reset is completed, the system can detect the relative position of the siphon cap and the siphon pipe in the detergent box again after a preset time, prevent the user from misoperation or incomplete solution, avoid the prompt of the fault again, increase the experience of the user, and improve the washing efficiency.

[0081] The present application provides a health monitoring scheme for the running state of an online device.

[0082] The user can also be notified of the siphon fault of the detergent box by using both the laundry machine body and the mobile phone APP.

[0083] The present application can also obtain and issue an alarm by the local control system after the prompt of the fault, remind the user to eliminate, upload to the cloud server after the alarm is issued by the local system, further determine and store after the processing by the cloud server, and provide a solution and send it to the mobile phone APP of the user, further increase the efficiency of solving the fault, and provide a device running scheme integrating the solution and the alarm.

[0084] When the washing machine dispenses detergent at different times, this invention can also monitor the position of the siphon cap in the corresponding dispensing chamber to determine the relative position between the siphon cap and the siphon tube in other dispensing chambers, and to determine whether there is a siphon malfunction, whether the siphon cap is installed properly or is blocked. This allows users to monitor the entire process of washing clothes, improves the washing effect, and enhances the user experience.

[0085] The present invention also provides a washing machine, including a detergent dispenser 5, wherein the detergent dispenser 5 has at least one receiving chamber, characterized in that: the receiving chamber includes a siphon tube disposed at the bottom of the receiving chamber and a siphon cap sleeved on the siphon tube;

[0086] The detection module includes a displacement sensor 7, which is disposed on the siphon cap and is used to detect the relative distance between the siphon cap and the siphon tube.

[0087] The control module, connected to the detection module, is used to obtain the detection distance to determine whether there is a siphon failure.

[0088] Specifically, such as Figure 4 As shown, by placing the displacement sensor 7 between the siphon tube and the siphon cap, the relative position of the siphon cap and the siphon tube can be detected more accurately, facilitating the detection of relevant data. The control module is connected to the detection module to obtain the detection distance to determine whether there is a siphon failure. The placement of the displacement sensor 7 does not affect the siphon process when adding detergent, thus improving the washing machine's performance in adding detergent and enhancing the user experience.

[0089] The displacement sensor 7 in this invention is not limited to being positioned between the siphon cap and the siphon tube inside the detergent box 5. It can be adjusted according to the amount of detergent dispensed into the detergent box 5, and can also detect multiple siphon caps simultaneously.

[0090] This invention provides a practical and intelligent solution for dispensing devices. By installing displacement sensors on the device and using displacement detection, the operating status of the device at different dispensing stages can be determined. Specifically, when the detergent dispenser is performing a siphon action, the relative position of the siphon cap and siphon tube is detected and compared with a preset value, and the result is fed back to the main control board and / or cloud server. After appropriate processing, a fault notification is sent to remind the user to return the siphon cap to its original position or to remove detergent adhering to the siphon tube and siphon cap. This intelligent IoT approach resolves issues such as abnormal siphon status in the dispensing device.

Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with equivalent embodiments within the scope of the technical solutions of the present application.
