Description

Technical Field

[0001] This invention belongs to the field of washing machines, and specifically relates to a method, apparatus, device, and washing machine for controlling the dehydration of a washing machine. Background Technology

[0002] Washing machines, under the control of a specified program, can complete all the tasks of washing, rinsing, spinning, and drying clothes, making people's lives more convenient and thus becoming an indispensable household appliance in people's daily lives.

[0003] During the spin-drying cycle, the washing machine becomes unbalanced due to the dehydration process, causing the outer drum to tilt or even move due to inertia. This leads to wear and tear, affecting the machine's lifespan, and also compromising safety. Furthermore, the varying weight and moisture content of the clothes required for each spin-drying cycle introduces numerous uncertainties affecting the spin-drying effect. Therefore, controlling the spin-drying process has always been a challenging problem in the washing machine industry. Current technologies commonly use methods such as determining the start and stop of the spin-drying cycle by judging the magnitude of the eccentricity, or controlling the completion of the spin-drying cycle based on a preset relationship between the eccentricity and the rotation speed.

[0004] The aforementioned methods all essentially control the dehydration process based on the magnitude of the eccentricity. However, the actual eccentricity is closely related to various factors such as the load size and measurement location, leading to measurement inaccuracies and complex control logic. Therefore, a dehydration control method with a simpler control process and more accurate results is needed to meet the higher demands of the market. Summary of the Invention

[0056] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention, and the present invention is not limited to the specific embodiments described below.

[0057] Washing machines, as cleaning appliances that use electrical energy to generate mechanical action to wash clothes, are widely used in production and daily life. However, the imbalance during the spin-drying stage is a phenomenon that occurs in washing machines that currently use the centrifugal force principle for spin-drying.

[0058] When a washing machine becomes unbalanced during spin-drying, the machine body will tilt. If the washing machine is already unbalanced during installation, it may cause serious wear and tear or collision, affecting the lifespan and safety of the machine.

[0059] Therefore, based on the imbalance phenomenon of washing machines, the present invention provides a method, device, equipment and washing machine for controlling the spin-drying of a washing machine. By installing a power-on / off module on the washing machine, the power-on / off module sends a corresponding signal to the controller according to the imbalance state of the washing machine. The controller then controls the spin-drying working state of the washing machine according to the signal. The signal acquisition method is simple and accurate, which can improve the accuracy of controlling the spin-drying working state of the washing machine.

[0060] The following provides a detailed description of the spin-drying control method, apparatus, equipment, and washing machine provided by the present invention.

[0061] Example 1

[0062] First, the power-on / off module involved in this invention will be described in detail. Figure 1 A simplified structural diagram of a power-on / off module provided in an embodiment of the present invention; Figure 2 This is a detailed diagram of the power on / off module.

[0063] Reference Figure 1As shown, the washing machine is equipped with at least one power-on / off module 101, which is fixedly mounted on the washing machine cover 102. (Refer to...) Figure 2 As shown, the power-on / off module is internally equipped with a conductive contact 201 and a movable conductive block 202, and the power-on / off module is also equipped with a housing 203.

[0064] For example, at least one power-on / off module is disposed on the lid of the washing machine. This application does not limit the shape or size of the washing machine lid. Figure 1 The cover shown is round, but in actual applications it can also be square or other special shapes.

[0065] When the washing machine is unbalanced during the spin cycle, the machine body will tilt due to the shaking, and the movable conductive block inside the power-on / off module will slide accordingly. When the conductive block disengages from the conductive contact due to sliding, that is, when the conductive contact and the conductive block are no longer in contact, the power-on / off module will send a disengagement signal; when the conductive block makes contact with the conductive contact, the power-on / off module will send a contact signal.

[0066] The washing machine's controller is connected to the power-on / off module, which transmits corresponding signals to the controller based on the contact status between the conductive block and the conductive contacts.

[0067] Alternatively, the power-on / off module can be located at any other fixed position on top of the washing machine, designed so that the power-on / off module can transmit the correct signal to the controller.

[0068] Secondly, the dehydration control method of the washing machine provided by the present invention will be described in detail.

[0069] Figure 3 This is a schematic flowchart of a spin-drying control method for a washing machine provided in Embodiment 1 of the present invention.

[0070] Reference Figure 3 As shown, this embodiment provides a spin-drying control method for a washing machine. The executing entity in this embodiment can be the controller of the washing machine. The method includes:

[0071] S301. Obtain the disconnection signal transmitted by each power-on / power-off module. The disconnection signal represents the signal generated when the conductive block in the power-on / power-off module is not in contact with the conductive contact.

[0072] For example, when the washing machine reaches the spin-drying stage and an imbalance occurs, the conductive block in each power-on / off module will tilt as the washing machine shakes. When the conductive block in the power-on / off module is no longer in contact with the conductive contact, a disconnection signal is generated, and each power-on / off module will transmit this disconnection signal to the controller.

[0073] S302. Adjust the spin-drying state of the washing machine according to the total number of disconnection signals received within a preset time.

[0074] The spin-drying operation of the washing machine includes at least one of two states: continuing to spin-dry and stopping spin-drying.

[0075] For example, the controller acquires the disconnection signal transmitted by each power-on / off module, and then determines whether the washing machine will continue the spin-drying process or stop the spin-drying process based on the total number of disconnection signals received within a preset time, thereby adjusting the spin-drying working state of the washing machine.

[0076] This application does not impose any restrictions on the specific values ​​of the preset time and the total number of times the signal is disconnected.

[0077] For example, the preset time can be set to 3 seconds, and the total number of disconnection signals can be set to 2. The controller can then determine whether to continue the spin-drying process or stop the spin-drying process based on whether the total number of disconnection signals received within 3 seconds reaches 2.

[0078] This invention adjusts the washing machine's spin-drying state by acquiring the disconnection signal transmitted from the power-on / off module and then based on the total number of disconnection signals received within a preset time. Since unbalanced spin-drying is an inherent phenomenon in washing machines that use centrifugal force, the controller directly determines the spin-drying state based on the disconnection signal generated when the conductive block in the power-on / off module disconnects from the conductive contacts due to the machine's shaking. This not only simplifies the control method but also, to avoid signal mistransmission due to normal shaking of the washing machine leading to low control accuracy, the total number of disconnection signals received within a preset time is used to determine the spin-drying state, further improving the accuracy of spin-drying control.

[0079] Example 2

[0080] Figure 4 This is a schematic flowchart of another dehydration control method for a washing machine provided in Embodiment 2 of the present invention.

[0081] Reference Figure 4 As shown, this embodiment provides another method for controlling the spin-drying of a washing machine. The executing entity in this embodiment can be the controller of the washing machine. The method includes:

[0082] S401. Obtain the disconnection signal transmitted by each power-on / power-off module. The disconnection signal represents the signal generated when the conductive block in the power-on / power-off module is not in contact with the conductive contact.

[0083] For example, this step can be referred to step S301 above, and will not be repeated here.

[0084] S402. If the total number of disconnection signals received within a preset time is greater than or equal to a preset threshold number, the washing machine is controlled to stop spinning and a first prompt message is issued; wherein, the first prompt message is used to prompt the user to adjust the placement of the washing machine.

[0085] For example, if the total number of disconnection signals received by the controller within a preset time is greater than or equal to a preset threshold, it indicates that the washing machine has completed the spin-drying process, and the controller stops the washing machine from spin-drying. Since the washing machine may shake due to imbalance during spin-drying, potentially causing it to move and the washing machine to be out of level, the washing machine can issue a first prompt message after spin-drying to remind the user to adjust the washing machine's position to be level.

[0086] The initial alert message can promptly remind users to adjust the washing machine's position if it is not positioned correctly for safe operation during the washing process, thus improving the washing machine's operational safety.

[0087] S403. If the total number of disconnection signals received within a preset time is less than a preset threshold number, then control the washing machine to continue the spin-drying process.

[0088] For example, if the total number of disconnection signals received by the controller within a preset time is less than a preset threshold, it indicates that the washing machine has not yet completed the spin-drying process, and the controller controls the washing machine to continue performing the spin-drying process. The condition that the total number of disconnection signals received is less than the preset threshold can be either that no disconnection signal is received, or that the total number of disconnection signals is less than the preset threshold.

[0089] S404. Determine whether the actual number of spin cycles of the washing machine has reached the preset number of spin cycles.

[0090] For example, after controlling the washing machine to stop spinning, the controller can also determine whether the washing machine has finished washing by judging whether the actual number of spin cycles has reached the preset number of spin cycles.

[0091] S405. If it is determined that the number of spin cycles of the washing machine is less than the preset number of spin cycles, then control the washing machine to switch to the water intake and rinsing process.

[0092] For example, the preset number of spin cycles for the entire washing process is determined when the washing program is selected, and is related to the actual number of washes, rinses, and spin cycles selected by the user. The preset number of spin cycles may be different for different programs, and this application does not impose any restrictions. If the controller detects that the actual number of spin cycles of the washing machine is less than the preset number of spin cycles, it means that the washing machine has not yet completed the entire washing task, and the controller controls the washing machine to switch to the water intake and rinsing process.

[0093] S406. If it is determined that the number of spin cycles of the washing machine is greater than or equal to the preset number of spin cycles, then the washing cycle is considered complete.

[0094] For example, if the controller detects that the actual number of spin cycles of the washing machine is greater than or equal to the preset number of spin cycles, it means that the washing machine has completed the last spin cycle and the controller determines that the washing process has ended.

[0095] In one example, before the washing machine starts working, the controller can also determine whether the washing machine is in a horizontal position based on whether a disconnection signal is received.

[0096] For example, after the washing machine is powered on, before it starts working, the controller first determines whether it has received a disconnection signal from the power on / off module to determine whether the washing machine is in a horizontal position before starting work, so as to ensure the safe operation of the washing machine.

[0097] If a disconnection signal is received, it is determined that the washing machine is not in a horizontal position, and a second prompt message is issued; wherein, the second prompt message is used to remind the user that the washing machine is not in a horizontal position.

[0098] If no disconnection signal is received, it is determined that the washing machine is placed horizontally, and the washing machine is controlled to complete the washing operation normally.

[0099] For example, if the controller receives a disconnection signal from the power-on / off module before the washing machine starts working, it indicates that the washing machine is not in a horizontal position. The controller then issues a second prompt message to remind the user that the washing machine is not in a horizontal position and needs to be adjusted before the washing operation can be completed.

[0100] If the controller does not receive a disconnection signal from the power-on / off module, it means that the washing machine is already in a horizontal position and there is no need to adjust its position. The washing machine can directly execute the washing program to complete the washing work.

[0101] The washing machine spin-drying control method provided in this embodiment of the invention acquires the disconnection signal transmitted by each power-on / off module, and determines the spin-drying working state of the washing machine based on the total number of disconnection signals received within a preset time. If the total number of disconnection signals received within the preset time is greater than or equal to a preset threshold, the washing machine is controlled to stop spin-drying and a first prompt message is issued. If the total number of disconnection signals received within the preset time is less than the preset threshold, the washing machine is controlled to continue spin-drying to achieve the preset moisture content requirement. After controlling the washing machine to stop spin-drying, it is then determined whether the actual number of spin-drying cycles has reached the preset number of spin-drying cycles. If it is determined that the number of spin-drying cycles is less than the preset number of spin-drying cycles, the washing machine is controlled to switch to the water intake rinsing process. If it is determined that the number of spin-drying cycles is greater than or equal to the preset number of spin-drying cycles, the washing process is determined to be over. The first prompt message is used to remind the user to adjust the placement of the washing machine. By reminding the user of the first prompt message, if the washing machine is not placed horizontally and does not meet the safety requirements for washing machine operation during the washing process, the user can be promptly reminded to make adjustments, thereby improving the operating safety of the washing machine. In addition, after controlling the washing machine to stop spinning, it also judges whether the actual number of spinning cycles has reached the preset number of spinning cycles, so as to control the washing machine to complete the subsequent washing work.

[0102] Example 3

[0103] Figure 5 This is a schematic flowchart of another dehydration control method for a washing machine provided in Embodiment 3 of the present invention.

[0104] This embodiment takes a washing machine equipped with two power-on / off modules, a preset time of 3 seconds, and a total number of disconnection signals of 2 as an example. During the spin-drying process, the controller receives signals transmitted by the two power-on / off modules to control the spin-drying status of the washing machine.

[0105] Reference Figure 5 As shown, during the spin-drying process, the conductive blocks in both power-on / off modules A and B are in contact with the conductive contacts. Both modules send a contact signal to the controller, keeping the washing machine powered on for spin-drying. When the spin-drying process becomes unbalanced, if both modules simultaneously disconnect from their contacts and send a disconnection signal to the controller, the spin-drying process stops. If only one module disconnects from its contact, the controller determines the spin-drying process based on the total number of disconnection signals received within 3 seconds. If the total number is less than 2, the spin-drying continues; otherwise, it stops. After the spin-drying process stops, it can be checked whether the actual number of spin-drying cycles is less than the preset number. If so, the washing cycle begins; otherwise, it ends.

[0106] In one example, the area of ​​the conductive block in each power-on / power-off module is larger than the area of ​​the conductive contact.

[0107] For example, the area of ​​the conductive block in each power-on / off module is larger than the area of ​​the conductive contact. The conductive contact can contact any position on the conductive block. As long as the conductive block and the conductive contact remain in contact, the washing machine is considered to be in a horizontal position. When placing the washing machine, if the actual position cannot be perfectly horizontal, it is only necessary to ensure that the conductive contact does not detach from the conductive block. The contact range between the conductive block and the conductive contact corresponds to the allowable error range of the ground not being perfectly horizontal. Within this error range, the washing machine can safely complete the washing operation, making it more practical. In addition, it will not emit erroneous signals due to normal shaking during the normal spin cycle of the washing machine. The present invention does not limit the specific size of the conductive contact and the conductive block.

[0108] In one example, there are two power-on / power-off modules.

[0109] Figure 6 This is a simplified structural diagram of another power-on / off module provided in an embodiment of the present invention. (Refer to...) Figure 6 As shown, there are two power-on / off modules, namely power-on / off module A and power-on / off module B. The first connecting line of power-on / off module A and the second connecting line of power-on / off module B are perpendicular to each other; the first connecting line connects the center point of power-on / off module A to the center point of the cover; the second connecting line connects the center point of power-on / off module B to the center point of the cover. Power-on / off modules A and B can also be located separately... Figure 4 Positions C and D are not restricted in this application.

[0110] Because the outer tub of the washing machine is suspended from the casing by a rod, due to the unique nature of this structure, the inertia at different positions may differ when the washing machine is unbalanced during the spin cycle. If only one power-on / off module is used, there is a possibility of inaccurate signal transmission. Therefore, by setting two power-on / off modules positioned at right angles, and then controlling the spin cycle based on the signals obtained from the two power-on / off modules, the accuracy is significantly improved.

[0111] In one example, a transparent housing is provided outside the power-on / off module; the conductive contacts and conductive blocks within the power-on / off module are all located inside the transparent housing. Installers and users of the washing machine can observe the position of the conductive blocks and their contact state with the conductive contacts through the transparent housing to determine whether the washing machine is placed horizontally. This provides visualization of the washing machine's horizontal placement and allows for adjustment of the washing machine's position to achieve horizontality based on the power-on / off module installed on it, without the need for any other external structures.

(Refer to...) Figure 7 As shown, the spin-drying control device 70 of the washing machine provided in this embodiment includes: an acquisition unit 701 and an adjustment unit 702.

[0115] The acquisition unit 701 is used to acquire the disconnection signal transmitted by each power-on / off module, wherein the disconnection signal represents the signal generated when the conductive block in the power-on / off module is not in contact with the conductive contact.

[0116] The adjustment unit 702 is used to adjust the spin-drying state of the washing machine according to the total number of disconnection signals received within a preset time.

The controller is connected to the power-on / off module. (Refer to...) Figure 8 As shown, the spin-drying control device 80 of the washing machine provided in this embodiment includes: an acquisition unit 801 and an adjustment unit 802.

[0121] The acquisition unit 801 is used to acquire the disconnection signal transmitted by each power-on / off module, wherein the disconnection signal represents the signal generated when the conductive block in the power-on / off module is not in contact with the conductive contact.

[0122] The adjustment unit 802 is used to adjust the spin-drying state of the washing machine according to the total number of disconnection signals received within a preset time.

[0123] In one example, the adjustment unit 802 includes a first control module 8021 and a second control module 8022.

[0124] The first control module 8021 is used to control the washing machine to stop spinning and issue a first prompt message if the total number of disconnection signals received within a preset time is greater than or equal to a preset number threshold. The first prompt message is used to prompt the user to adjust the placement of the washing machine.

[0125] The second control module 8022 is used to control the washing machine to continue the spin-drying operation if the total number of disconnection signals received within a preset time is less than a preset threshold number.

[0126] In one example, the spin-drying control device 80 of the washing machine provided in this embodiment further includes: a first spin-drying control unit 803 and a second spin-drying control unit 804.

[0127] The first spin-dry control unit 803 is used to control the washing machine to switch to the water intake and rinsing process if it is determined that the number of spin-drying cycles of the washing machine is less than the preset number of spin-drying cycles.

[0128] The second spin-dry control unit 804 is used to determine the end of the washing process if it is determined that the number of spin-dry cycles of the washing machine is greater than or equal to the preset number of spin-dry cycles.

[0129] In one example, the spin-drying control device 80 of the washing machine also includes: a first monitoring unit 805 and a second monitoring unit 806.

[0130] The first monitoring unit 805 is used to determine that the washing machine is not in a horizontal position if it receives a disconnection signal before the washing machine starts working, and to issue a second prompt message, wherein the second prompt message is used to remind the user that the washing machine is not in a horizontal position.

[0131] The second monitoring unit 806 is used to determine that the washing machine is in a horizontal position if no disconnection signal is received before the washing machine starts working, and to control the washing machine to complete the washing work normally.

[0132] In one example, the area of ​​the conductive block in each power-on / power-off module is larger than the area of ​​the conductive contact.

[0133] In one example, there are two power-on / off modules; the first connecting line of one of the power-on / off modules and the second connecting line of the other power-on / off module are perpendicular to each other; the first connecting line is the connecting line between the center point of one power-on / off module and the center point of the cover; the second connecting line is the connecting line between the center point of the other power-on / off module and the center point of the cover.

[0134] In one example, the power-on / off module is equipped with a transparent housing; the conductive contacts and conductive blocks in the power-on / off module are all located inside the transparent housing of the power-on / off module.
