[0052] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0053] The structure of the existing intelligent washing machine includes a table panel, a control panel and a washing barrel. The control panel is provided with a display panel, a key and a knob. The user can select different washing programs for washing clothes of different materials through the key and the knob. When the control panel of the washing machine fails within the warranty period, the user should wait for the after-sales personnel to detect and repair on site, or send the washing machine to the designated repair point for after-sales repair. The connection between the table panel and the control panel is pasted with a seal. If the after-sales personnel finds that the seal is damaged within the warranty period, the after-sales personnel cannot provide free repair service for the user.

[0054] In one scenario, some users privately disassemble the washing machine, repair the washing machine according to experience, and then re-paste the imitated seal on the washing machine after repair, concealing the process of privately repairing the washing machine. Since the after-sales personnel cannot accurately identify the imitated seal, the after-sales personnel cannot identify the washing machine that has been privately repaired. The after-sales personnel cannot identify whether the failure of the washing machine is a problem of the equipment itself or caused by human, which affects the maintenance efficiency of the equipment, causes waste of resources, and damages the interests of the manufacturer.

[0055] In order to solve the above technical problems and achieve the purpose of preventing the user from falsely reporting the washing machine repair information, the present embodiment provides a washing machine anti-disassembly alarm device, which comprises a supporting component, an alarm switch, an alarm module, a communication module and a power module. In the disassembled state of the washing machine table, the alarm switch is no longer in contact with the alarm switch, so that the alarm switch is in the pop-up state. At this time, the power module is electrically connected with the alarm module, the alarm module generates an alarm signal and sends it to the communication module, and the communication module sends the alarm signal to the server. The alarm signal indicates that the washing machine is privately disassembled. The present application monitors the condition that the washing machine is privately disassembled by using the washing machine anti-disassembly alarm device, improves the accuracy of identifying that the user privately repairs the washing machine, and achieves the purpose of preventing the user from falsely reporting the washing machine repair information.

[0056] The technical solutions of the present application are described in detail below with specific examples. The following specific examples can be combined with each other, and some examples may not be described in detail for the same or similar concepts or processes.

[0057] Figure 1 Structure diagram of the washing machine anti-disassembly alarm device provided by the embodiment of the present application Figure 1 As shown in Figure 1 , the washing machine anti-disassembly alarm device provided by the embodiment of the present application includes a support component 10, a power supply module 20, an alarm switch 30, a communication module 40 and an alarm module 50. Among them, the support component 10 is installed below the washing machine table, the alarm switch 30, the alarm module 50, the communication module 40 and the power supply module 20 are installed above the washing machine main control board, the alarm switch 30 is connected with the alarm module 50 and the power supply module 20 respectively, and the alarm module 50 is connected with the communication module 40.

[0058] In the embodiment provided by the present application, when the alarm switch 30 is in the off state in the pressed state and in the on state in the pop-up state. When the washing machine table is in the undismounted state, the support component 10 abuts against the alarm switch 30, and the alarm switch 30 is in the pressed state; when the washing machine table is in the dismounted state, the support component 10 no longer abuts against the alarm switch 30, and the alarm switch 30 is in the pop-up state. When the alarm switch 30 is in the pop-up state, the power supply module 20 is electrically connected with the alarm module 50, the alarm module 50 generates an alarm signal, and sends the alarm signal to the communication module 40. After the communication module 40 receives the alarm signal, the alarm signal is sent to the server, wherein the alarm signal is used to indicate that the washing machine is disassembled privately.

[0059] From the above embodiment, it can be seen that through the washing machine anti-disassembly alarm device provided by the embodiment of the present application, when the washing machine table is in the undismounted state, the support component abuts against the alarm switch to make the alarm switch in the pressed state, and when the washing machine table is dismounted, the support component no longer abuts against the alarm switch, so that the alarm switch is in the pop-up state. By detecting the pressed and pop-up states of the alarm switch, the alarm module generates an alarm signal, and the communication module sends the alarm signal to the server. Before going on-site maintenance, the after-sales personnel query whether the washing machine is disassembled privately through the server, if the after-sales personnel identify that the washing machine to be maintained has been disassembled privately, the after-sales personnel will no longer provide free on-site maintenance for the user. Through the washing machine anti-disassembly alarm device provided by the embodiment of the present application, the situation that the washing machine is disassembled privately is monitored, the accuracy of identifying that the user privately maintains the washing machine is improved, and the purpose of preventing the user from falsely reporting the washing machine maintenance information is achieved.

[0060] Figure 2 Structure diagram of the washing machine anti-disassembly alarm device provided by the embodiment of the present application Figure 2 As shown in Figure 2As shown, the alarm switch 30 is a double control normally closed push button switch. The alarm switch 30 further includes a push button 301, a first normally closed contact 302 and a second normally closed contact 303. The power supply module 20 includes a power supply first end 201 and a power supply second end 202. The alarm module 50 includes a signal detection port 501 and a power supply connection port 502. Wherein, when the countertop is in the undismounted state, the push button 301 is pressed by the support component 10, when the countertop is no longer in the undismounted state, the push button 301 is no longer pressed by the support component 10, and the push button 301 is popped up. The power supply first end 201 is grounded, the power supply second end 202 is connected with the first normally closed contact first end 3021 and the second normally closed contact first end 3031 respectively, the first normally closed contact second end 3022 is connected with the signal detection port 501 of the alarm module, and the second normally closed contact second end 3032 is connected with the power supply connection port 502 of the alarm module.

[0061] In the embodiments provided by the present application Figure 1 and Figure 2 When the countertop is in the undismounted state, the push button 301 is pressed by the support component 10. Since the alarm switch 30 is a double control normally closed push button switch, when the push button 301 is in the pressed state, the alarm switch 30 is in the open state, that is, the power supply second end 202 is in the open circuit state with the first normally closed contact first end 3021 and the second normally closed contact first end 3031. At this time, there is no power supply between the power supply module 20 and the alarm module 50, and no signal is detected in the signal detection port 501 of the alarm module.

[0062] In the embodiments provided by the present application Figure 1 and Figure 2 When the countertop is in the undismounted state, the push button 301 is pressed by the support component 10. Since the alarm switch 30 is a double control normally closed push button switch, when the push button 301 is in the pressed state, the alarm switch 30 is in the open state, that is, the power supply second end 202 is in the open circuit state with the first normally closed contact first end 3021 and the second normally closed contact first end 3031. At this time, there is no power supply between the power supply module 20 and the alarm module 50, and no signal is detected in the signal detection port 501 of the alarm module.

[0063] In a possible implementation, the alarm module 50 is a controller of the washing machine, the signal detection port 501 of the alarm module 50 is an input / output port of the controller, and the power connection port 502 of the alarm module 50 is a power port of the controller. When the table top is in a disassembled state, the button 301 is no longer pressed by the supporting part 10, the button 301 is popped up, and the alarm switch 30 is in a closed state, that is, the second end 202 of the power supply has current passing through between the first end 3021 of the first normally closed contact and the first end 3031 of the second normally closed contact. At this time, the power supply module 20 provides power for the controller through the power connection port 502, and the controller generates an alarm signal according to the voltage detected by the signal detection port 501. When the controller detects the voltage through the signal detection port 501, the controller generates an alarm signal according to the detected voltage, and sends the alarm signal to the server through the communication module 40.

[0064] For example, the communication module 40 can be a wireless communication module, that is, the alarm module 50 can send the alarm signal to the after-sales server of the manufacturer through a wireless network. The alarm signal contains the device identification of the washing machine and the information that the washing machine is disassembled privately. The after-sales personnel of the manufacturer can identify that the washing machine has been disassembled privately by the user according to the alarm signal, and no longer provide free maintenance service for the washing machine.

[0065] From the above embodiment, it can be seen that by installing the washing machine anti-disassembly alarm device designed in the application on the washing machine, the button in the alarm switch is pressed by the supporting part, when the table top of the washing machine is disassembled, the button is popped up, the first normally closed contact and the second normally closed contact of the switch are closed, the power supply module and the alarm module are electrically connected, the power supply module provides power for the alarm module through the power connection port of the alarm module, the alarm module generates an alarm signal according to the voltage detected by the signal detection port, and sends the alarm signal to the server through the communication module, so as to identify that the washing machine is disassembled privately. The application provides power for the alarm module through the power connection port of the alarm module, so that the washing machine can still detect and send an alarm signal under the condition of power failure, and the accuracy of identifying the disassembly of the washing machine is improved.

[0066] Figure 3 The structure of the washing machine anti-disassembly alarm device provided in the embodiment of the application Figure 3 As shown in Figure 4 , the washing machine anti-disassembly alarm device provided in the embodiment of the application further comprises a load module 60, the first end 601 of the load module is connected with the second end 3022 of the first normally closed contact, and the second end 602 of the load module is connected with the signal detection port 501 of the alarm module 50. The load module 60 is used for adjusting the port voltage of the signal detection port 501.

[0067] In the embodiment provided by the present application, when the table top is in the disassembled state, the button 301 is no longer pressed by the supporting part 10, and the button 301 is popped up. Since the alarm switch 30 is a double-control normally closed button switch, when the button 301 is in the popped-up state, the alarm switch 30 is in the closed state, the power module 20 provides power for the alarm module 50 through the power connection port 502, and the alarm module 50 generates an alarm signal according to the voltage detected through the signal detection port 501. Specifically, the signal detection port 501 of the alarm module 50 can be an input / output port. The alarm module 50 generates an alarm signal according to the voltage detected through the input / output port. In order to ensure the safety of the alarm module 50, the actual detected voltage of the input / output port of the alarm module should be less than the rated port voltage of the input / output port. For example, when the power module 20 is a 5V DC power supply, the rated port voltage of the input / output port is usually 3.3V. Therefore, a load module 60 needs to be arranged between the power module 20 and the input / output port to divide the voltage, so as to adjust the actual port voltage of the input / output port to be between 0V and 3.3V. For example, the load module 60 can be a variable resistor. By adjusting the size of the variable resistor, the actual port voltage of the input / output port is less than the rated voltage of the port.

[0068] As can be seen from the above embodiment, by arranging the washing machine anti-disassembly alarm device further comprising a load module, the port voltage of the signal detection port of the alarm module is adjusted by the load module, so that the port voltage of the signal detection port of the alarm module is less than the rated voltage of the port, and the safety of the hardware is improved.

[0069] In a possible implementation, the washing machine anti-disassembly alarm device provided by the embodiment of the present application further comprises a thing chain module. The thing chain module is connected with the alarm module 50, and the thing chain module is used to receive the alarm signal transmitted by the alarm module 50 and send the alarm signal to a block chain server, so that the block chain server closes the after-sales service permission of the washing machine according to the alarm signal.

[0070] In the embodiment of the present application, specifically, the thing chain module can be a trusted Internet of Things ecological block chain module, which adopts a multi-network Smart LTE Cat 4 module with an eight-core 64-bit ARM Cortex-A53 processor and is equipped with an interesting chain technology block chain operating system. The thing chain module has complete hardware expansion capability and has functions such as Internet of Things device digital identity authentication, privacy protection, data evidence, and data traceability, and can efficiently enable various terminal devices to realize trusted data collection and privacy protection. For example, the thing chain module adopts a GD331-BCE intelligent module.

[0071] In the embodiment of the present application, specifically, the data transmission port of the material chain module is connected with the data transmission port of the alarm module 50, and the material chain module receives the alarm signal transmitted by the alarm module 50. On the one hand, the material chain module uploads the alarm signal to the block chain server and chains on the cloud platform, and on the other hand, the material chain module equipment directly chains, truly realizes the source data chaining, and ensures that the data itself is real and reliable. The block chain server generates a certificate that the equipment has been disassembled according to the alarm signal, and closes the after-sales service permission of the washing machine.

[0072] From the above embodiment, it can be seen that by arranging the material chain module connected with the alarm module in the washing machine anti-disassembly alarm device, after the alarm module 50 transmits the alarm signal to the material chain module, the material chain module transmits the alarm signal to the block chain server, so that the block chain server can close the after-sales service permission of the washing machine according to the alarm signal. By using the material chain module to transmit the alarm signal for chaining, the risk of being tampered is reduced, and the reliability of data transmission is improved.

[0073] In a possible implementation, the power module 20 in the washing machine anti-disassembly alarm device is a storage battery. The storage battery is connected with the power supply of the washing machine, and when the power supply of the washing machine is connected with the external power supply, the storage battery is charged by the power supply of the washing machine. By charging the storage battery with the power supply of the washing machine, the power module 20 is always in an electrified state, avoiding the situation that the washing machine anti-disassembly alarm device cannot accurately monitor the disassembly of the washing machine due to lack of power of the power module 20.

[0074] In a possible implementation, the washing machine anti-disassembly alarm device provided by the embodiment of the present application further includes an upper shell and a lower shell, the upper shell and the lower shell are detachably connected, the upper shell is installed on the table surface of the washing machine, and the lower shell is installed on the main control board of the washing machine. The support component, the alarm switch, the alarm module, the communication module and the power module are installed inside the space formed by the upper shell and the lower shell, and the support component is embedded in the inside of the upper shell, and the alarm switch, the alarm module, the communication module and the power module are embedded in the inside of the lower shell.

[0075] In the embodiment of the present application, the upper shell and the lower shell of the washing machine anti-disassembly alarm device are packaged in a sealed shell, and the washing machine anti-disassembly alarm device is taken as a separate device, which is convenient to install in different types of washing machines and is not easy to be found by users. By avoiding the customer to find the washing machine anti-disassembly alarm device, the accuracy of the washing machine anti-disassembly alarm device to identify the disassembly of the washing machine is improved.

[0076] Figure 4 The washing machine anti-disassembly alarm method provided by the embodiment of the present application is shown in the flow chart. Figure 1 The washing machine anti-disassembly alarm method provided by the embodiment of the present application includes the following steps:

[0077] 401、support component in the washing machine top surface is not removed state, with the alarm switch, and make the alarm switch in the press state; in the washing machine top surface is removed state, no longer with the alarm switch, so that the alarm switch in the pop-up state.

[0078] 402、power module in the alarm switch in the pop-up state, with the alarm module electrically conductive, so that the alarm module generates an alarm signal, and send the alarm signal to the communication module.

[0079] 403、communication module sends the alarm signal to the server, the alarm signal is used to indicate that the washing machine is privately disassembled.

[0080] The steps 401 to 403 in the embodiment of the application are respectively Figure 5 The function of the washing machine anti-disassembly alarm device described in the embodiment is repeated, and will not be described here.

[0081] The washing machine anti-disassembly alarm method provided in the embodiment, through the washing machine anti-disassembly alarm device provided in the embodiment of the application, when the washing machine top surface is not disassembled, the support component is used to abut against the alarm switch to make the alarm switch in the press state, when the washing machine top surface is disassembled, the support component no longer abuts against the alarm switch, so that the alarm switch is in the pop-up state. By detecting the press and pop-up state of the alarm switch, the alarm module generates an alarm signal, and the communication module sends the alarm signal to the server. The after-sales personnel can query whether the washing machine is privately disassembled through the server before going to the user's home for maintenance. If the after-sales personnel identifies that the washing machine to be repaired has been privately disassembled, the after-sales personnel will no longer provide free on-site maintenance for the user. The washing machine anti-disassembly alarm device provided in the embodiment of the application monitors the private disassembly of the washing machine, improves the accuracy of identifying the private repair of the washing machine by the user, and achieves the purpose of preventing the user from falsely reporting the washing machine maintenance information.
