DETAILED DESCRIPTION

[0046] The technical solutions of the present disclosure are described hereinafter through specific embodiments in conjunction with the drawings.

Embodiment 1

[0047] FIG. 1 is a flowchart illustrating a control method for an Internet-of-Things washing machine according to an embodiment 1. The control method includes the steps described below.

[0048] In Step 110, device information and failure information of a washing machine sent by the washing machine is received.

[0049] The device information includes information for identifying the washing machine. The failure information can indicate a failure displayed by the washing machine. For example, the water feeding is abnormal, an indicator light is not working when the power is turned on, and so on.

[0050] In Step 120, an installation information database is queried for a first number of washing machines having same device information in a preset area.

[0051] In Step 130, an alarm history record database is queried for a second number of washing machines having same failure information within a first preset time duration in the preset area if the first number is greater than a first preset threshold.

[0052] A residential area, a same street or a same building may be selected as the preset area. The first preset time may be a time duration before the washing machine fails, or may be a time duration that is relatively close to time when the washing machine fails, such as a time duration of 10 minutes from the time when the washing machine fails.

[0053] In Step 140, a failure cause is determined based on the first number and the second number.

[0054] The failure cause of the washing machine may be determined according to value range of the first number and the second number. For example, causes of abnormal water feeding may include: low tap water pressure and loss of tap feedwater; and water leakage from the washing machine.

[0055] The failure cause of the washing machine can be determined by the above-mentioned control method instead of by the user himself/herself. Cumbersome work for the user is then reduced and user experiences are improved.

Embodiment 2

[0056] As shown in FIGS. 2 and 3, a flowchart of a control method according to an embodiment 2 includes the steps described below.

[0057] In the embodiment, failure information may be that water feeding is abnormal.

[0058] On the basis of the above-mentioned embodiment, as shown in FIG. 2, the control method may include the steps below.

[0059] In Step 210, an alarm history record database is queried for a second number of washing machines having same failure information within a first preset time duration in the preset area if the first number is greater than a first preset threshold.

[0060] In Step 220, a failure cause is determined based on the first number and the second number.

[0061] In Step 230, the alarm history record database is updated according to the failure cause.

[0062] In Step 240, the failure cause is sent to the washing machine so that the washing machine displays the failure cause, and the failure cause is also sent to a user terminal for prompting a user.

[0063] Referring to FIG. 3, the Step 210 may further include the steps described below.

[0064] In Step 211, it is determined whether the first number is greater than the first preset threshold. If the first number is greater than the first preset threshold, Step 212 is performed. If the first number is not greater than the first preset threshold, Step 240 is performed.

[0065] In the Step 212, an alarm history record database is queried for a second number of washing machines having same failure information within a first preset time duration in the preset area.

[0066] In the Step 240, the failure information is sent to the washing machine so that the failure information is displayed on the washing machine, and the failure information is also sent to a user terminal for prompting the user.

[0067] Since the number of washing machines in the preset area does not reach a set number, the failure cause cannot be determined by the above-mentioned method.

[0068] Based on the above-mentioned embodiment, as shown in FIG. 3, the step in which the failure cause is determined based on the first number and the second number may include the steps described below.

[0069] In Step 221, it is determined whether the second number is greater than the second preset threshold. If the second number is greater than the second preset threshold, Step 222 is performed. If the second number is not greater than the second preset threshold, Step 223 is performed.

[0070] In the Step 222, the failure cause of the washing machine is that the tap water pressure is low or that the water is stopped, and no after-sale maintenance is required.

[0071] In the Step 223, the after-sale personnel is needed to carry out the on-site maintenance.

[0072] The maintenance information is sent to the after-sale outlet. The after-sale outlet may actively contact the user for on-site maintenance, avoiding wasting the time of the user.

[0073] A relatively accurate determination can be made by using the above-mentioned method for automatically determining the failure cause after the number of washing machines in a certain area reaches a certain number. For example, more than 10 washing machines are set in one area.

Embodiment 3

[0074] An embodiment provides a control apparatus for an Internet-of-Things washing machine. As shown in FIG. 4, the apparatus implements the control method for an Internet-of-Things washing machine described in the above embodiments.

[0078] The failure cause determination module 340 is configured to determine a failure cause based on the first number and the second number.

[0079] The failure information may be that water feeding is abnormal. The failure cause determination module 340 may be configured to determine the failure cause of the washing machine as low tap water pressure or loss of feedwater if the second number is greater than a second preset threshold, and determine the failure cause of the washing machine as water leakage from the washing machine if the second number is less than or equal to the second preset threshold.

[0080] Optionally, the control apparatus further includes an update module 350. The update module 350 is configured to update the alarm history record database according to the failure cause.

[0081] Optionally, the control apparatus further includes a failure cause sending module 360. The failure cause sending module 360 is configured to send the failure cause to the washing machine so that the washing machine displays the failure cause, and send the failure cause to a user terminal for prompting the user.

[0082] Optionally, the control apparatus further includes a failure information sending module 370. The failure information sending module 370 is configured to send the failure information to the washing machine so that the washing machine displays the failure information and send the failure information to a user terminal for prompting the user if the first number is less than or equal to the first preset threshold.

Embodiment 4

[0083] As shown in FIG. 5, an embodiment provides a control system for an Internet-of-Things washing machine. The system includes a control apparatus for an Internet-of-Things washing machine 410, the washing machine 410 and a user terminal 430. The control apparatus may be configured in a server 420. The washing machine 410 is configured to determine whether the washing machine 410 fails, and transmit device information and failure information of the washing machine 410 to the server 420 when the washing machine 410 fails.

[0084] The washing machine 410 may include a control module 411, a data communication processing module 412 and a display module 413.

[0085] The control module 411 is configured to control water feeding of the washing machine 410, determine whether a water level of the washing machine 410 reaches a set value within a second preset time duration, control a water inlet valve to be closed if the water level of the washing machine 410 reaches the set value within the second preset time duration, and control the data communication processing module 412 to send device information and failure information of the washing machine 410 if the water level of the washing machine 410 does not reach the set value within the second preset time duration.

[0086] The data communication processing module 412 is configured to transmit the device information and the failure information to the server 420, and receive a failure cause sent by the server 420.

[0087] The display module 413 is configured to display the failure cause of the washing machine 410.

[0088] The user terminal 430 is configured to receive the failure cause and the failure information sent by the server 420.

[0089] The control module 411 and the data communication processing module 412 may be implemented by a central processor, a digital signal processor (DSP) or a field programmable gate array (FPGA). The central processor, the DSP and the FGPA may include a storage medium storing executable instructions for executing the above-mentioned method. The storage medium may be a non-transitory storage medium, including a read-only memory (ROM), a random access memory (RAM) or another medium that may store program codes, and may also be a transitory storage medium. The display module 413 may be a display, such as a liquid crystal display.

[0090] The process of determining the failure cause of the water feeding abnormality of the washing machine 410 by using the control system in the embodiment is described below.

[0091] As shown in FIG. 6, the washing machine 410 is started, the water inlet valve is opened, and the control module 411 determines whether the water level of the washing machine 410 reaches the set value. If the water level of the washing machine 410 reaches the set value, the water inlet valve is closed and the laundry is carried out. If the water level of the washing machine 410 does not reach the set value, it is determined whether the second preset time duration is reached. If the second preset time duration is not reached, the water inlet valve is opened for continued water feeding. If the second preset time duration is reached, the water feeding abnormality is indicated, the water inlet valve is closed, the laundry is suspended, and the control module 411 controls the data communication module to transmit the device information and the failure information to the server 420.

[0092] The server 420 receives the device information and the failure information of the washing machine 410 sent by the washing machine 410 through the information receiving module, and stores the device information and the failure information of the washing machine 410 in the alarm history record database. The first query module is used to query an installation information database for a first number of washing machines 410 having the same device information in a preset area. If the first number is greater than the first preset threshold, a second query module is used to query the alarm history record database for a second number of washing machines 410 having the same failure information within a first preset time duration in the preset area. The failure cause determination module is used to determine a failure cause based on the first number and the second number. If the first number is less than or equal to the first preset threshold, the failure cause is determined to be water feeding abnormality. The information of water feeding abnormality is sent to the washing machine 410 so that the failure information is displayed through the display module 413 of the washing machine 410, and the failure information is sent to a user terminal 430 for prompting the user.

[0093] The step in which the failure cause is determined by the failure cause determination module based on the first number and the second number may include the following steps. If the first number is greater than the second preset threshold, the failure cause of the water feeding abnormality is determined as low tap water pressure or loss of feedwater. The alarm history record database is updated according to the failure cause. The failure cause is sent to the washing machine 410, is displayed through the display module 413 of the washing machine 410, and is sent to the user terminal 430 for prompting the user. If the second number is less than or equal to the second preset threshold, the failure cause of water feeding abnormality is determined as water leakage from the washing machine. The alarm history record database is updated according to the failure cause. The failure cause is sent to the washing machine 410, is displayed through the display module 413 of the washing machine 410, and is sent to the user terminal 430 for prompting the user.
