Description

Technical Field

[0001] The present invention belongs to the technical field of washing, and in particular relates to a washing machine and a washing machine control method. Background Art

[0002] Currently, common washing machines on the market are all plug-and-play models. They simply need to be plugged into a mains power source and powered on to start working. If the mains power is disconnected, the washing machine will not work. Therefore, when the washing machine is plugged into a mains power source and powered on, if there is a sudden power outage, the washing machine will stop working and will not be able to complete the laundry task. If the power outage lasts for a long time, the user will need to manually remove the clothes being washed and wash them manually, which is time-consuming and laborious. If the user does not remove the soaked clothes in time, the clothes will be soaked in the washing machine for too long, causing damage or secondary contamination. Therefore, a power outage in the washing machine causes great inconvenience to the user, affecting the user's experience of the quick and convenient washing machine, and thus reducing user satisfaction with the product.

[0003] To address the issue of plug-and-play washing machines becoming inoperable during a mains power outage, some washing machine products incorporate a built-in backup power supply. By integrating a backup power supply into the washing machine, the washing machine operates from the mains power supply under normal operating conditions. In the event of a mains power outage, the backup power supply takes over. For example, Chinese patent application publication number CN111519386A discloses an auxiliary power supply for a washing machine. An external power supply and the auxiliary power supply are connected in parallel. In the event of a power outage or other malfunction, the auxiliary power supply provides power to the washing machine. In this technical solution, after the auxiliary power supply is used to power the washing machine, a first sensor is used to detect the water level while the washing machine drum is stationary. If the first sensor indicates that the water level is above a predetermined threshold, the control unit automatically executes a first set of preset actions, draining the washing machine through the drainage system and unlocking the washing machine door to safely open it, allowing the user to remove clothes or other laundry from the drum. If the first sensor indicates that the water level is below the predetermined threshold, the control unit automatically executes a second set of preset actions, unlocking the washing machine door to safely open the watertight door and allow the user to remove clothes or other laundry from the drum.

[0004] Although the above-mentioned technical solution provides an auxiliary power supply to supply power to the washing machine in the event of a power outage or other malfunction of the external power supply, allowing the washing machine door to be opened, allowing the user to safely remove the clothes or other items of clothing from the drum, the following problems still exist: after removing the clothes or items of clothing, the user still needs to wash them manually, which is time-consuming and laborious. Moreover, if the user lacks the necessary skills to remove the clothes, the clothes, already soaked in water, may be left in the washing machine for too long, causing damage or contamination. Therefore, this still causes significant inconvenience to the user, and may even result in losses due to damage or contamination of the clothes. Summary of the Invention

[0005] The object of the present invention is to provide a washing machine and a washing machine control method, so as to solve the problem that the washing machine can still reasonably process clothes when the external power supply is cut off or fails, thereby avoiding inconvenience and loss to the user.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] To address the technical problem of ensuring that a washing machine can still properly process laundry when the external power supply is disconnected or faulty, thus avoiding inconvenience and loss to the user, the present invention not only provides an auxiliary power supply within the washing machine but also proposes a washing machine and washing machine control method from a washing machine control perspective. When the auxiliary power supply is selected to power the washing machine, the remaining power of the auxiliary power supply and the washing machine's status parameters when the external power supply is abnormal are detected. The actual washing operation is determined based on the remaining power and the washing machine's status parameters, thereby completing the washing of the laundry within the washing machine. For more specific implementations of the technical solutions and the resulting technical effects, please refer to the detailed descriptions of the following embodiments.

[0046] Figure 1 and Figure 2 An embodiment of the washing machine of the present invention is shown, wherein Figure 1 is a schematic structural diagram of this embodiment, Figure 2 It is the control principle diagram of this embodiment.

[0047] like Figure 1 and Figure 2As shown, the washing machine of this embodiment includes a housing 11, within which is formed a tub (not shown) for holding wash water and laundry. A computer board 12 is mounted above housing 11, on which are located components such as a controller 121 and a memory. Also located within housing 11 is a washing action unit 13, connected to computer board 12 and configured to perform the washing process under the control of controller 121. As will be understood by those skilled in the art, washing action unit 13 includes, but is not limited to, motors, belts, and other components that drive the rotating components of the washing machine (such as the drum and impeller).

[0048] The washing machine shown in this embodiment is a pulsator type washing machine, but is not limited thereto and may also be a drum type washing machine.

[0049] When the washing machine is a pulsator type washing machine, the motor drives the pulsator to rotate through a belt deceleration. Under the program control of the controller, the pulsator stirs the water, detergent and clothes in forward and reverse rotation. The washed clothes are rubbed by the mechanical action of the rotating pulsator and the chemical action of the detergent aqueous solution in the washing tub through forward and reverse stirring to remove stains and clean the clothes.

[0050] When the washing machine is a drum type washing machine, the motor drives the drum to rotate through the reduction pulley. The clothes rise to a high point as the drum rotates and then fall. The mechanical action of the clothes being continuously dropped, hit and squeezed and the chemical action of the detergent aqueous solution achieve the purpose of removing stains and cleaning the clothes.

[0051] An auxiliary power supply 15 is further provided on the upper portion of the housing 11 , near the computer board 12 , and the auxiliary power supply 15 can provide auxiliary power to the controller 121 and the washing action unit 13 .

[0052] The washing machine further includes a power plug 14, which is used to connect an external power source to the washing machine, and utilize the external power source to provide external power to the controller 121 and the washing action unit 13. The external power source generally refers to a power source in a mains power supply network.

[0053] The washing machine also includes a power supply switching unit 17 for selecting whether the controller 121 and the washing action unit 13 are powered by the external power supply 16 or by the auxiliary power supply 15. Specifically, when the external power supply is normal, the controller 121 and the washing action unit 13 are powered by the external power supply 16. When the external power supply is abnormal, such as when the external power supply is out of power or fails, the controller 121 and the washing action unit 13 are powered by the auxiliary power supply 15. This ensures that even when the external power supply 16 is unable to power the washing machine, the auxiliary power supply 15 can still provide power to the washing machine.

[0054] While the washing machine is performing a washing operation using power from external power supply 16, if an abnormality occurs in external power supply 16, power switching unit 17 switches to auxiliary power supply 15, which then powers controller 121 and washing action unit 13. After switching to auxiliary power supply 15, controller 121 obtains the remaining power of auxiliary power supply 15 and the status parameters of the washing machine at the time of the abnormality. Based on the remaining power and the status parameters, controller 121 determines the actual washing operation to be performed by the washing machine when powered by auxiliary power supply 15, and then controls washing action unit 13 to complete the actual washing operation.

[0055] The controller 121 can obtain the remaining power of the auxiliary power supply 15 using existing technology. Since the washing machine is controlled by the controller 121 during the washing process, the controller 121 can obtain the real-time status parameters of the washing machine, such as the washing program currently being executed, the current progress of the washing program, and so on. Therefore, when an abnormality occurs in the external power supply 16, the controller 121 can accurately know the status parameters of the washing machine at that moment. After obtaining the remaining power and the status parameters of the washing machine, the controller 121 can determine the actual washing operation based on certain pre-set determination methods. This actual washing operation will be a reasonable and appropriate washing operation that comprehensively considers the power provided by the auxiliary power supply 15 and the current washing state of the washing machine. It will fully utilize the energy of the auxiliary power supply 15 to continue the washing operation of the current washing process as much as possible, so as to complete the washing process of the selected washing machine as much as possible.

[0056] By arranging an auxiliary power supply in the washing machine, when the external power supply encounters abnormal conditions such as power outage or failure, the auxiliary power supply is selected to power the controller and washing action unit in the washing machine that need power, and the remaining power of the auxiliary power supply and the status parameters of the washing machine when the external power supply is abnormal are automatically detected. The actual washing operation is determined according to the remaining power and the status parameters of the washing machine, and the washing machine completes the washing of the built-in clothes, reducing the inconvenience of users washing clothes manually, and avoiding damage or pollution to clothes caused by users not handling clothes in time and not completing washing, thereby reducing user losses, thereby providing better services for washing machine users and enhancing the market competitiveness of washing machine products.

[0057] In some preferred embodiments, the state parameters of the washing machine include at least a washing program and a time process. The time process refers to the time the washing program has been running. The actual washing operation is determined based on the remaining power and the state parameters of the washing machine, specifically including:

[0058] The controller 121 determines the actual power consumption required to complete the washing program according to the washing program and the time process. The calculation of the actual power consumption can be achieved by using existing technology or future technology, which is not specifically limited in this embodiment.

[0059] Then, it is determined whether the remaining power is greater than the actual power consumption.

[0060] If so, it is determined that the actual washing operation is to complete the washing program and meet the actual washing needs.

[0061] Otherwise, the actual washing operation is determined to be a simplified washing program whose required power consumption does not exceed the remaining power. The simplified washing program is a washing operation that is as close to the remaining washing program as possible based on the remaining power of the auxiliary power supply 15. Furthermore, as a preferred embodiment, the simplified washing program at least includes a spin cycle to drain detergent from the clothes, thereby saving the user the inconvenience of manual washing and reducing detergent contamination of the clothes.

[0062] In some more preferred embodiments, to simplify the operation, information of simplified washing programs corresponding to the remaining power intervals is stored in the memory of the washing machine. Determining that the actual washing operation is a simplified washing program corresponding to the remaining power does not exceed the power consumption specifically includes:

[0063] The remaining power interval to which the remaining power belongs is determined, and a simplified washing program corresponding to the remaining power interval to which the remaining power belongs is selected from the information of the one-to-one correspondence between the remaining power intervals and the simplified washing programs, and determined as the actual washing operation.

[0064] In an optional embodiment, the information of the simplified washing program corresponding to the remaining power interval is as follows:

[0065] When the remaining power is less than 20%, the washing machine can choose to complete the program of single spin for 10 minutes to spin and dry the clothes being washed in the washing machine to prevent the clothes from being soaked for a long time;

[0066] When the remaining power is 20%-40%, the washing machine can choose to complete the program of quick wash for 15 minutes;

[0067] When the remaining power is 40%-60%, the washing machine can choose to complete the program as simple washing for 30 minutes;

[0068] When the remaining power is 60%-80%, the washing machine can choose to complete the program as regular washing for 45 minutes;

[0069] When the remaining power is 80%-100%, the washing machine can choose to complete the program of delicate washing for 60 minutes.

[0070] In some other preferred embodiments, when an abnormality occurs in the external power supply 16, the power supply is not switched immediately. Instead, after the time when the external power supply 16 is abnormal reaches the set abnormal time, the power supply switching unit 17 switches to the auxiliary power supply 15 for power supply. The purpose of such a setting is that if the external power supply 16 is temporarily abnormal, such as tripping or temporarily shutting down the external power supply 16 for some protection or some operation, the external power supply 16 can return to normal in a short time. In this case, if the auxiliary power supply 15 is switched immediately after the abnormality, it will not only cause the consumption of the auxiliary power supply 15, but also affect the normal washing of clothes. Therefore, a correction time is set for the abnormality of the external power supply 16, that is, the abnormal time is set, for example, 10 minutes. After the time when the external power supply 16 is abnormal reaches the set abnormal time, the power supply is switched.

[0071] To enhance the user-friendliness and interactivity of the washing machine, users are given the ability to independently choose when switching power and washing programs. Therefore, in some preferred embodiments, a power supply anomaly reminder is issued within a set duration after the external power supply 16 experiences an anomaly. For example, an indicator light 18 is provided on the upper portion of the washing machine housing 11 to provide a power supply anomaly warning. Alternatively, an audible alarm unit can be provided to provide an audible warning, or both an audible and an indicator light can be used. Upon receiving the warning signal, the user can choose whether to switch the power supply and receive a switching instruction. For example, a selection button for switching the power supply and washing program appears on the washing machine's operating panel. Pressing the selection button indicates whether to switch or not. Furthermore, to ensure smooth execution of the washing operation if the user fails to provide a switching instruction in a timely manner, the switching instruction is issued with a time limit, for example, 5 minutes. That is, the user selects a time within 5 minutes after the external power supply 16 experiences an anomaly, which reaches the set duration. The power supply switching unit 17 determines whether a switching instruction is received; if a switching instruction is received within the duration, the power supply switching unit 17 immediately switches to the auxiliary power supply 15 to power the controller 121 and the washing action unit 13; if no switching instruction is received within the duration, when the duration is reached, the power supply switching unit 17 switches to the auxiliary power supply 15 to power the controller 121 and the washing action unit 13.

[0072] To ensure continuous power supply from the auxiliary power supply 15, in some other preferred embodiments, the auxiliary power supply 15 includes a storage unit and a charging unit. When the external power supply 16 is functioning normally, the charging unit uses the external power supply 16 to charge the storage unit, preparing for auxiliary power supply after the next power outage. Furthermore, once the storage unit is fully charged, charging stops to prevent overcharging that could shorten its lifespan.

[0073] Figure 3FIG2 is a flow chart of an embodiment of a method for controlling a washing machine according to the present invention, specifically a flow chart of an embodiment of controlling a washing machine with an auxiliary power supply when the external power supply is abnormal.

[0074] like Figure 3 As shown, this embodiment uses the following process to realize the control of the washing machine:

[0075] Step 31: When the external power supply for the washing machine is abnormal, switch the auxiliary power supply to power the washing machine.

[0076] Step 32: Obtain the remaining power of the auxiliary power supply and the status parameters of the washing machine when the external power supply is abnormal, determine the actual washing operation, and control the washing machine to perform the actual washing operation.

[0077] In some preferred embodiments, the state parameters of the washing machine include at least a washing program and a time process. The time process refers to the time the washing program has been running. The actual washing operation is determined based on the remaining power and the state parameters of the washing machine, specifically including:

[0078] The actual power consumption required to complete the washing program is determined based on the washing program and the time process. The calculation of the actual power consumption can be achieved using existing technology or future technology, which is not specifically limited in this embodiment.

[0079] Then, it is determined whether the remaining power is greater than the actual power consumption.

[0080] If so, it is determined that the actual washing operation is to complete the washing program and meet the actual washing needs.

[0081] Otherwise, the actual washing operation is determined to be a simplified washing program whose required power consumption does not exceed the remaining power. The simplified washing program is a washing operation that is as close as possible to the remaining washing program process that can be completed based on the remaining power of the auxiliary power supply.

[0082] In some more preferred embodiments, to simplify the operation, information of simplified washing programs corresponding to the remaining power intervals is stored in the memory of the washing machine. Determining that the actual washing operation is a simplified washing program corresponding to the remaining power does not exceed the power consumption specifically includes:

[0083] The remaining power interval to which the remaining power belongs is determined, and a simplified washing program corresponding to the remaining power interval to which the remaining power belongs is selected from the information of the one-to-one correspondence between the remaining power intervals and the simplified washing programs, and determined as the actual washing operation.

[0084] For more specific implementation process, principles and technical effects, please refer to Figure 1 and Figure 2 The corresponding description of the washing machine embodiment.

[0085] Figure 4 FIG2 is a flow chart of another embodiment of a method for controlling a washing machine according to the present invention, specifically, a flow chart of an embodiment of controlling a washing machine with an auxiliary power supply when the external power supply is abnormal.

[0086] like Figure 4 As shown, this embodiment uses the following process to realize the control of the washing machine:

[0087] Step 41: When the external power supply for the washing machine is abnormal, obtain the time when the abnormality occurs.

[0088] Step 42: Determine whether the time when the external power supply is abnormal reaches the set abnormal time. If so, execute step 43; otherwise, go to step 41 and continue to obtain the real time when the abnormality occurs in order to continue to determine the execution time.

[0089] Step 43: Determine whether a switching instruction is received within the duration after the external power supply abnormality occurs and reaches the set abnormality time. If so, go to step 45; otherwise, go to step 44.

[0090] Step 44: Determine whether the external power supply abnormality time reaches the set abnormality time and then reaches the duration. If so, go to step 45; otherwise, go to step 43 and continue to determine.

[0091] Step 45: Switch to auxiliary power to power the washing machine.

[0092] This step is executed based on the judgment results of step 43 and step 44. Specifically, if a switching instruction is received within the duration after the time when the external power supply becomes abnormal reaches the set abnormal time, the auxiliary power supply is immediately switched to power the washing machine; if no switching instruction is received within the duration, the auxiliary power supply is switched to power the washing machine when the duration is reached.

[0093] The specific implementation of each step of this embodiment, the meaning of the parameters, the purpose of the step setting and the technical effects produced can be referred to Figure 1 and Figure 2 The corresponding description of the washing machine embodiment will not be repeated here.

[0094] In some other embodiments, user interactivity may be ignored, and only a correction time may be set for the abnormality of the external power supply, that is, an abnormality time is set. After the abnormality of the external power supply reaches the set abnormality time, the auxiliary power supply is switched to power the washing machine.

[0095] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents.
