[0047] The washing machine of the present disclosure is equipped with a battery. When there is no external power source, the battery can replace the external power source to supply power to various electrical components of the washing machine 1.

[0048] Compared with the canned steel and cement that are usually used in the counterweight and balance blocks of existing washing machines, the washing machine 1 of the present invention has a battery arranged inside the counterweight and balance block 70. The battery can have a dual function. The battery can not only serve as a part of the counterweight and balance block 70, but also play a role of counterweight and balance in the operation of the washing machine 1. The weight of the battery can replace at least a part of the mass of the steel and cement of the counterweight and balance block in the original washing machine, which can be used to prevent the inner drum of the washing machine 1 from vibrating strongly during operation. Moreover, the battery can also realize the function of storing electric energy.

Optionally, each counterweight balancing block 70 includes a battery, and the batteries of the plurality of counterweight balancing blocks 70 are connected in series to form a series battery group 700.

[0051] The washing machine 1 further includes a communication interface 61 disposed on the housing 20 , and the circuit board 40 is also connected to the communication interface 61 .

[0052] In a preferred embodiment, the communication interface 61 may include a type-C interface, for example, so that it can support forward and reverse insertion, and can support fast charging and discharging functions. Optionally, the communication interface 61 can be a communication female head, and the communication female head can be connected to the circuit board 40 through a connecting harness 41, such as a flat cable.

Figures 9 to 11 As shown and combined with reference Fig.12 The circuit board 40 includes a main control module 401 and a power supply circuit 402. The main control module 401 can be connected to the power line 10 and the communication interface 61 respectively through the power supply circuit 402. The main control module 401 is also connected to the series battery group 700 composed of batteries on the counterweight balancing block 70, and can control the series battery group 700 accordingly.

[0054] The main control module 401 on the circuit board 40 is connected to the power line 10 through the power supply circuit 402. Thus, power transmission can be achieved. The main control module 401 can be used to control the power input and output of the series battery pack 700.

[0055] In addition, the main control module 401 can also convert the kinetic energy of the motor 50 into electrical energy and store it in the series battery pack 700 when the motor 50 is stopped, thereby realizing energy recovery.

[0056] The main control module 401 on the circuit board 40 is connected to the communication interface 61 through the power supply circuit 402. Therefore, information transmission can be provided to the circuit board 40 through the communication interface 61 to achieve program input, or electronic file input / output, etc. In a preferred embodiment, the circuit board 40 may also include a storage module 80, which is connected to the main control module 401 and can be used to store data. Therefore, when the file is large, the file can be stored in the storage module 80 on the circuit board 40.

[0057] Combined with reference Fig.10 and Fig.11As shown, the power line 10 is connected to the power supply circuit 402 on the circuit board 40 and can charge the batteries on the left counterweight balancing block 71, the right counterweight balancing block 72 and the rear counterweight balancing block 73 through the power line main harness 11. The power line main harness 11 can branch out into the first power line harness 12, the second power line harness 13 and the third power line harness 14. In addition, the power line 10 is connected to the batteries on the left counterweight balancing block 71, the right counterweight balancing block 72 and the rear counterweight balancing block 73 through the power supply circuit 402 on the circuit board 40 and then through the first power line harness 12, the second power line harness 13 and the third power line harness 14, respectively, so that the batteries on the left counterweight balancing block 71, the right counterweight balancing block 72 and the rear counterweight balancing block 73 can be charged respectively. The power cord main harness 11 can also branch out into a fourth power cord harness 15 . The power cord 10 is connected to the motor 50 through the power supply circuit 402 on the circuit board 40 and then through the fourth power cord harness 15 , so that it can be used to power the motor 50 .

[0058] The main control module 401 on the circuit board 40 can be connected to the batteries on the left counterweight balance block 71, the right counterweight balance block 72 and the rear counterweight balance block 73 respectively through the first circuit board wiring harness 42, the second circuit board wiring harness 43 and the third circuit board wiring harness 44, so that it can be used to control the power input and output of the batteries on the left counterweight balance block 71, the right counterweight balance block 72 and the rear counterweight balance block 73.

[0059] It is understandable that the above embodiment is to illustrate the connection between components by taking the washing machine 1 including three balancing blocks as an example. However, the connection method of the battery on the counterweight balancing block 70 of the washing machine 1 disclosed in the present invention is not limited to that shown above, and can be reasonably adjusted according to the actual number and setting position of the counterweight balancing block 70.

[0060] Continue to refer to Fig.12The circuit board 40 also includes a voltage sampling module 403, a current sampling module 404 and a temperature sampling module 405. The voltage sampling module 403, the current sampling module 404 and the temperature sampling module 405 can be used to collect the battery voltage, battery current and battery temperature of the series battery group 700 respectively. The voltage sampling module 403, the current sampling module 404 and the temperature sampling module 405 are all connected to the main control module 401, and the voltage sampling module 403, the current sampling module 404 and the temperature sampling module 405 are all connected to the series battery group 700. The main control module 401 can perform corresponding control according to at least one of the battery voltage, battery current and battery temperature of the series battery group 700 collected by the voltage sampling module 403, the current sampling module 404 and the temperature sampling module 405. For example, when the battery temperature of the series battery group 700 collected by the temperature sampling module 405 is higher than a predetermined temperature threshold, in order to protect the battery, the main control module 401 on the circuit board 40 can control to stop the charging and discharging operations on the battery on the counterweight balancing block 70, thereby protecting the battery on the counterweight balancing block 70 from overtemperature. When the battery voltage of the series battery group 700 collected by the voltage sampling module 403 is higher than a predetermined voltage threshold, the main control module 401 on the circuit board 40 can perform overvoltage protection on the battery on the counterweight balancing block 70 to prevent the battery from being damaged. When the battery current of the series battery group 700 collected by the current sampling module 404 is higher than a predetermined current threshold, the main control module 401 on the circuit board 40 can perform overcurrent protection on the battery on the counterweight balancing block 70 to prevent the battery from being damaged.

For example, when the SOC value of the series battery group 700 estimated by the battery SOC estimation module 406 according to the battery voltage and battery current sampled by the voltage sampling module 403 and the current sampling module 404 is higher than the predetermined SOC value, the main control module 401 on the circuit board 40 can control to stop the charging operation of the battery on the counterweight balancing block 70 to prevent the battery from being overcharged.

[0063] Optionally, the circuit board 40 further includes a battery balancing module 407, which is connected to the main control module 401 and the series battery group 700. The main control module 401 can control the battery balancing module 407 to perform corresponding operations on the series battery group 700 according to the battery voltage of the series battery group 700 collected by the voltage sampling module 403, so as to ensure that the voltage of each battery in the series battery group 700 remains balanced.

[0064] Optionally, the circuit board 40 may further include a protection module 409, which is connected to the power supply circuit 402 and the main control module 401. The main control module 401 may perform corresponding protection on the circuit board 40 by controlling the protection module 409. For example, when an abnormality occurs, the main control module 401 may cut off the power supply of the power supply circuit 402 through the protection module 409 to perform power-off protection on the circuit board 40.

[0065] Optionally, the circuit board 40 may further include a display module 410, and the display module 410 is connected to the main control module 401. The main control module 401 may control the display module 410 to display corresponding data and information.

[0066] The washing machine 1 disclosed in the present invention can add several additional functions to white appliances such as the washing machine 1 by configuring the communication interface 61, and can realize communication transmission when the washing machine 1 is not connected to the network. For example, when the program version needs to be upgraded, but the washing machine 1 does not support networking, or the location where it is placed cannot receive the network, the new version of the program can be connected and transmitted through a smart phone for upgrading, so that the after-sales engineer can send the new version of the program to the user, and the user can transmit and install it by himself after obtaining the communication protocol authorization; it is also possible to power the circuit board 40 in the washing machine 1 and complete the relevant configuration through tools such as mobile phones or laptops when the washing machine 1 is not powered on, such as installing a new machine (some models with refrigeration systems need to be left to stand for a period of time before installation to prevent compressor abnormalities), and the washing machine 1 can be configured to connect to the home network without plugging in the power supply. The washing machine 1 disclosed in the present invention can also realize charging and discharging functions such as outdoor camping through the communication interface 61 by configuring the communication interface 61 and the battery.
