Description

Technical Field

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

[0002] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other programs, such as washing machines, washer-dryers, etc.

[0003] The dehydration process is to rotate the drum containing the clothes and use centrifugal force to remove the water from the clothes. The distribution of the clothes in the drum during the dehydration process is difficult to control. The clothes will be unevenly distributed in the drum due to knots or entanglements during the turning process, causing the drum to be eccentric, thus generating noise.

[0004] At present, in response to the above problems, some washing equipment has made improvements to the dehydration control method, specifically: a preset eccentricity limit value is set, and the eccentricity value of the barrel is obtained during the dehydration process. If the obtained eccentricity value is lower than the eccentricity limit value, the barrel is controlled to continue to increase its speed until the maximum speed of the dehydration process is reached, so as to efficiently dehydrate the clothes in the barrel; if the obtained eccentricity value is higher than the eccentricity limit value, the eccentricity correction is performed.

[0005] In the above technical solution, the eccentricity limit is a set value and cannot be adjusted according to the actual situation during the dehydration process. In this way, the upper limit of the noise decibel generated during the dehydration process is also fixed. If the noise decibel allowed by the user is low, and the eccentricity limit in this method is too large, it may generate a noise decibel higher than the user's allowed; if the user requires a higher dehydration efficiency, and this method is limited by the eccentricity limit, the speed may not continue to rise to the optimal dehydration speed, and the dehydration efficiency cannot be guaranteed to be high.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The object of the present invention is to provide a dehydration control method and a washing device for a washing machine, so as to switch and adjust the eccentricity limit value according to the user's requirements for noise and dehydration efficiency during the dehydration process to meet the user's actual needs.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A dehydration control method for a washing device, wherein the washing device is provided with an eccentricity limit value. During the dehydration process, if it is detected that the eccentricity value of a barrel of the washing device is lower than the eccentricity limit value, the barrel is controlled to increase in speed.

[0010] The dehydration program includes a slow dehydration mode and a fast dehydration mode. The eccentricity limit value corresponding to the slow dehydration mode is smaller than the eccentricity limit value corresponding to the fast dehydration mode. During the dehydration process, the slow dehydration mode and the fast dehydration mode can be switched and the eccentricity limit value can be adjusted to the eccentricity limit value corresponding to the switched mode.

[0011] Furthermore, the low noise time period and the non-low noise time period are preset, and the switching execution of the slow stripping mode and the fast stripping mode includes:

[0012] Determine whether the time period during which the dehydration program is executed is a low noise period. If so, the control first executes the slow dehydration mode t 1 time, then execute the fast stripping mode, otherwise, the control first executes the slow stripping mode t 2 time, and then execute the quick release mode, where t 1 >t 2 .

[0013] Further, determining whether the time period during which the dehydration program is executed is a low noise time period includes:

[0014] Get the time points t corresponding to the start and end of the dehydration program respectively 开始 ,t 结束 , if t 开始 ,t 结束 If both belong to the low-noise time period, it is judged to belong to the low-noise time period; otherwise, it is judged to not completely belong to the low-noise time period.

[0015] Furthermore, when it is determined that the time period is not completely low noise, if t 开始 It belongs to the low noise period, t 结束 If it is not a low noise time period, then obtain the time t of the low noise time period to control the duration t of the slow-off mode. 2 It is positively correlated with the acquisition time t.

[0016] Furthermore, when it is determined that the time period is not completely low noise, if t 开始 Belongs to the non-low noise period, t 结束 During the low noise period, the quick release mode will be shortened.

[0017] Furthermore, the washing device can receive a switching instruction from the user. If the time period of the dehydration program belongs to a low-noise time period and a switching instruction is received during the execution of the slow dehydration mode, the control switches the slow dehydration mode to the fast dehydration mode.

[0018] Further, the switching to execute the slow stripping mode and the fast stripping mode includes:

[0019] Preset distance value Q 0, obtain the distance value Q between the user and the washing device, and compare the obtained distance value Q with the preset distance value Q 0 The size of 0 , you can control the switch from slow-release mode to fast-release mode.

[0020] Furthermore, the preset time length S 0 , when the distance value obtained is Q≤Q 0 When the cumulative Q≤Q 0 The duration S of the calculation is compared with the preset duration S. 0 The size of S≥S 0 , the control switches from slow-release mode to fast-release mode.

[0021] Furthermore, the types of the laundry in the washing device are obtained, and the corresponding slow-spinning mode operation duration and fast-spinning mode operation duration are selected according to the obtained types.

[0022] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0023] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0024] In the present invention, the corresponding eccentricity limit value in the slow spin mode is smaller. Under the limitation of the smaller eccentricity limit value, the upper limit value of the noise decibel generated is low, which can ensure that no large noise is generated in this mode; the corresponding eccentricity limit value in the fast spin mode is larger, so that during the dehydration process, the barrel body of the washing device can be allowed to rise to a larger rotation speed, and the eccentricity correction will not be frequently performed, so that the dehydration efficiency of the washing device is higher; during the dehydration process of the present invention, the slow spin mode and the fast spin mode can be switched to reasonably select the eccentricity limit value that can meet the user's needs according to the actual situation.

[0025] In the present invention, if the time period during which the dehydration process is executed belongs to the low noise time period, the slow dehydration mode is controlled to be executed for a longer time, so that most of the washing water is dehydrated in the slow dehydration mode, and no high decibel noise is generated in this stage, thereby avoiding excessive noise disturbing the user. After a large amount of washing water is dehydrated in the slow dehydration mode, it is not easy to generate high noise when dehydrating further. At this time, the fast dehydration mode is controlled to be executed for a shorter time to speed up the dehydration process.

[0026] The washing device of the present invention is controlled by the dehydration control method of the present invention. The dehydration mode can be reasonably switched during the dehydration process of the washing device, which not only avoids noise interference to the user, but also improves the dehydration efficiency according to the actual needs of the user.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other procedures, such as washing machines, washer-dryers, etc.; the washing equipment includes a barrel for holding clothes. When the washing equipment dehydrates, the barrel is controlled to rotate and centrifugal force is used to separate water from the clothes.

[0039] like Figures 1 to 5 As shown, the present invention discloses a dehydration control method for a washing device. The washing device is provided with an eccentricity limit value. During the dehydration process, if it is detected that the eccentricity value of the washing device barrel is lower than the eccentricity limit value, the barrel is controlled to increase speed.

[0040] The dehydration program includes a slow dehydration mode and a fast dehydration mode. The eccentricity limit value corresponding to the slow dehydration mode is smaller than the eccentricity limit value corresponding to the fast dehydration mode. During the dehydration process, the slow dehydration mode and the fast dehydration mode can be switched and the eccentricity limit value can be adjusted to the eccentricity limit value corresponding to the switched mode.

[0041] Among them, switching to execute the slow removal mode and the fast removal mode includes: first executing the slow removal mode and then switching to the fast removal mode; or, first executing the fast removal mode and then switching to the slow removal mode; or, switching in a cycle according to the rule of "slow removal mode─fast removal mode─slow removal mode─fast removal mode".

[0042] Specifically, as an embodiment of the present invention, Figure 1 As shown, the control steps include:

[0043] S1, start;

[0044] S2, preset eccentricity limit value M of slow release mode 1 , eccentricity limit value M of quick release mode 2 ;

[0045] S3, execute slow stripping mode;

[0046] S4, obtaining the eccentricity value M;

[0047] S5. Determine whether the obtained eccentricity value M is greater than or equal to the preset eccentricity limit value M 1 ; If yes, go to step S61, otherwise, go to step S62;

[0048] S61, control to perform eccentricity correction, and execute step S7;

[0049] The eccentricity correction method includes: controlling to reduce the speed of the barrel, and controlling the barrel to rotate forward and reverse to shake the clothes; or controlling water to flow into the barrel to correct the eccentricity;

[0050] S62, controlling the barrel to increase its speed to the target speed, and executing step S7;

[0051] S7, determine whether the slow-off mode is ended; if so, execute step S8; otherwise, return to step S3;

[0052] S8, switch to quick release mode;

[0053] S9, obtaining the eccentricity value M;

[0054] S10, judging whether the obtained eccentricity value M is greater than or equal to the preset eccentricity limit value M 2 ; If yes, go to step S111, otherwise, go to step S112;

[0055] S111, control to perform eccentricity correction, and execute step S12;

[0056] S112, controlling the barrel to increase its speed to the target speed, and executing step S12;

[0057] S12, determine whether the quick release mode is ended; if so, execute step S13; otherwise, return to step S9;

[0058] S13, end.

[0059] The washing device comprises a box body, in which a barrel body is arranged; the barrel body is hung in the box body through a suspension rod, a foot is arranged at the bottom of the box body, and n pressure sensors for detecting load-bearing force values ​​are arranged at both ends of the suspension rod or at different positions on the foot.

[0060] In step S4 and step S9 of this embodiment, the method for obtaining the eccentricity value M includes: detecting and recording the detection values ​​G of n pressure sensors 11 , G 12 …G 1n ; Calculate G 11 , G 12 …G 1n The difference between the maximum and minimum values ​​ΔG is taken as the eccentricity value M.

[0061] In the present invention, the corresponding eccentricity limit value in the slow-stripping mode is relatively small. Under the limitation of the small eccentricity limit value, the upper limit value of the noise decibel generated is relatively low, which can ensure that no large noise is generated in this mode. The corresponding eccentricity limit value in the fast-stripping mode is relatively large, so that during the dehydration process, the barrel of the washing device can be allowed to rise to a larger rotation speed, and the eccentricity correction will not be frequently performed, so that the dehydration efficiency of the washing device is relatively high. During the dehydration process of the present invention, the slow-stripping mode and the fast-stripping mode can be switched to reasonably select the eccentricity limit value that can meet the user's needs according to the actual situation.

[0062] As an embodiment of the present invention, a low-noise time period and a non-low-noise time period are preset, for example, 23:00-6:00 in a day is set as a low-noise time period, and the rest of the time is set as a non-low-noise time period.

[0063] Switching to execute the slow dehydration mode and the fast dehydration mode includes: determining whether the time period during which the dehydration program is executed belongs to the low noise time period, and if so, controlling the slow dehydration mode to be executed first. 1 time, then execute the fast stripping mode, otherwise, the control first executes the slow stripping mode t 2 time, and then execute the quick release mode, where t 1 >t 2 .

[0064] Specifically, Figure 2 As shown, the control steps of this embodiment are as follows:

[0065] S1, start;

[0066] S2, preset low noise time period and non-low noise time period, preset time t 1 ,t 2 ;

[0067] S3, obtaining the time period during which the dehydration program is executed;

[0068] S4, determining whether the time period during which the dehydration process is executed is a low noise time period; if so, executing step S51; otherwise, executing step S52;

[0069] S51, execute slow stripping mode 1 After the time has passed, execute step S6;

[0070] S52, execute slow stripping mode 2 After the time has passed, execute step S6;

[0071] S6. Switch to quick release mode.

[0072] In step S3 of this embodiment, determining whether the time period during which the dehydration program is executed belongs to the low-noise time period includes: first obtaining the time period during which the dehydration program is executed; and then determining whether the obtained time period belongs to the low-noise time period.

[0073] The time period when the dehydration program is executed includes: the washing device includes a washing program, a rinsing program, and a dehydration program that are executed in sequence; the time when the washing program starts is recorded, and the washing time and the rinsing time are accumulated based on the time, and the time when the dehydration program starts is calculated, and the time period when the dehydration program is executed is estimated in combination with the time when the dehydration program is executed. For example:

[0074] The washing equipment sequentially executes a 20-minute washing program, a 10-minute rinsing program, and a 5-minute dehydration program. If the washing program starts at 10:00, the rinsing program starts at 10:20, the dehydration program starts at 10:30, and the dehydration is completed at 10:35. The time period for the dehydration program is 10:30-10:35.

[0075] In this embodiment, if the time period during which the dehydration process is executed belongs to the low noise period, the slow dehydration mode is controlled to be executed for a longer time, so that most of the washing water is removed in the slow dehydration mode, and no high decibel noise is generated during this stage, thereby avoiding excessive noise disturbing the user. After a large amount of washing water is removed in the slow dehydration mode, it is not easy to generate high noise when dehydration is continued. At this time, the quick dehydration mode is controlled to be executed for a shorter time to speed up the dehydration process.

[0076] As an implementation of this embodiment, determining whether the time period during which the dehydration program is executed is a low noise time period includes:

[0077] Get the time points t corresponding to the start and end of the dehydration program respectively 开始 ,t 结束 , if t 开始 ,t 结束 If both of them belong to the low noise time period, it is judged to belong to the low noise time period, otherwise, it is judged to be not completely in the low noise time period. Among them, not completely belonging to the low noise time period includes: not belonging to the low noise time period at all and only part of the time belongs to the low noise time period.

[0078] Specifically, Figure 3 As shown, the control steps of this embodiment are as follows:

[0079] S1, start;

[0080] S2, preset low noise time period and non-low noise time period, preset time t 1 ,t 2 ;

[0081] S3. Obtain the time point t corresponding to the start of the dehydration program 开始 , get the time point t corresponding to the end of the dehydration program 结束 ;

[0082] S4. Determine t 开始 ,t 结束 Whether they are all in the low noise time period; if so, execute step S51; otherwise, execute step S52;

[0083] S51, execute slow stripping mode 1 After the time has passed, execute step S6;

[0084] S52, execute slow stripping mode 2 After the time has passed, execute step S6;

[0085] S6. Switch to quick release mode.

[0086] This embodiment makes an accurate division of the time period for executing the dehydration program. Only when the dehydration program starts executing, the time point t 开始 The time point corresponding to the end of the dehydration program is t 结束 Only when they all belong to the low-noise time period can it be determined that the time period when the dehydration program is executed belongs to the low-noise time period, which lays the foundation for the subsequent accurate control of the running time of the slow dehydration mode.

[0087] As another implementation of this embodiment, when it is determined that the time period during which the dehydration program is executed is not completely a low noise time period, if t 开始 It belongs to the low noise period, t 结束 If it is not a low noise time period, then obtain the time t of the low noise time period to control the duration t of the slow-off mode. 2 It is positively correlated with the acquisition time t. For example:

[0088] Set 23:00-6:00 a.m. as the low-noise time period; the rest of the time as the non-low-noise time period; the dehydration program duration is 5 minutes; if t 开始 is 5:57, t 结束 If it is 6:02, the time t belonging to the low noise period is 3 minutes, and the duration t of the slow stripping mode is controlled. 2 is 3 minutes; if t 开始 is 5:56, t 结束 If it is 6:01, the time t belonging to the low noise period is 4 minutes, and the duration t of the slow stripping mode is controlled. 2 For 4 minutes.

[0089] In this embodiment, the duration t of the slow stripping mode is controlled. 2It is positively correlated with the time t that belongs to the low-noise period during the dehydration program operation period, accurately avoiding the generation of loud noise during the low-noise period. Once it is not in the low-noise stage, it can be controlled to switch to the quick dehydration mode to speed up the dehydration process.

[0090] Furthermore, when it is determined that the time period is not completely low noise, if t 开始 Belongs to the non-low noise period, t 结束 In the low noise period, the quick release mode is controlled to shorten the duration. For example: if t 开始 It is 22:57, t 结束 In this embodiment, the duration of the quick-release mode is controlled to be shortened to avoid generating noise for a long time in the low-noise time period.

[0091] As an implementation of this embodiment, the washing device can receive a switching instruction from the user. If the time period of the dehydration program belongs to a low-noise time period and a switching instruction is received during the execution of the slow dehydration mode, the control switches the slow dehydration mode to the fast dehydration mode.

[0092] Specifically, a button is provided on the washing device, and if a touch command of the button is received, the slow stripping mode is controlled to be switched to the fast stripping mode. Preferably, after switching to the fast stripping mode, the rotation speed of the barrel is further controlled to be reduced.

[0093] In this embodiment, although it is in a low noise period, in order to meet the personalized needs of users, the washing device can respond to the user's switching instructions and artificially switch from the slow dehydration mode to the fast dehydration mode to meet the user's needs for fast dehydration.

[0094] As an embodiment of the present invention, the switching execution slow stripping mode and fast stripping mode includes: presetting the distance value Q 0 , obtain the distance value Q between the user and the washing device, and compare the obtained distance value Q with the preset distance value Q 0 The size of 0 , you can control the switch from slow-release mode to fast-release mode.

[0095] Specifically, Figure 4 As shown, the control steps include:

[0096] S1, start;

[0097] S2, preset distance value Q 0 , preset time t 1 ;

[0098] S3, execute slow stripping mode;

[0099] S4, obtaining the distance value Q between the user and the washing device;

[0100] S5. Determine whether the obtained distance value Q is less than or equal to the preset distance value Q 0 ; If yes, go to step S7; otherwise, go to step S6;

[0101] S6: Determine whether the duration of the slow-off mode reaches t 1 ; If yes, proceed to step S7; otherwise, return to step S3;

[0102] S7, switch to quick release mode.

[0103] In this embodiment, the washing device is provided with a distance measuring device for obtaining the distance between the user and the washing device, such as a radar device, an infrared sensor, a camera, etc. In step S4 of this embodiment, the distance measuring device is controlled to start and obtain the distance value Q between the user and the washing device.

[0104] In this embodiment, if the distance Q between the user and the washing device is less than or equal to the preset distance Q 0 , indicating that the user is in front of the washing machine. At this time, the control switches from the slow dehydration mode to the fast dehydration mode to quickly complete the dehydration and make it convenient for the user to take away the dehydrated clothes.

[0105] As an implementation of this embodiment, the preset time length S 0 , when the distance value obtained is Q≤Q 0 When the cumulative Q≤Q 0 The duration S of the calculation is compared with the preset duration S. 0 The size of S≥S 0 , the control switches from slow-release mode to fast-release mode.

[0106] Specifically, Figure 5 As shown, the control steps of this embodiment include:

[0107] S1, start;

[0108] S2, preset distance value Q 0 , preset time t 1 , preset duration S 0 ; Among them, the preset duration S 0 Can be 1min;

[0109] S3, execute slow stripping mode;

[0110] S4, obtaining the distance value Q between the user and the washing device;

[0111] S5. Determine whether the obtained distance value Q is less than or equal to the preset distance value Q 0 ; If yes, execute step S51; otherwise, execute step S6;

[0112] S51, cumulative Q≤Q 0 Compare the cumulative duration S to see if it is greater than or equal to the preset duration S 0 , if yes, execute step S7; otherwise, execute step S6;

[0113] S6: Determine whether the duration of the slow-off mode reaches t 1 ; If yes, proceed to step S7; otherwise, return to step S3;

[0114] S7, switch to quick release mode.

[0115] In this embodiment, if the cumulative Q≤Q 0 The duration S is greater than or equal to the preset duration S 0 , it means that the user has stayed in front of the washing machine for a while. At this time, the control switches from slow dehydration mode to fast dehydration mode to quickly complete the dehydration and make it convenient for the user to take away the dehydrated clothes.

[0116] In this embodiment, when the accumulated Q≤Q 0 The duration S is less than the preset duration S 0 It indicates that although the user stays in front of the washing machine, the stay time is short, and the user may just pass by the washing machine. At this time, the dehydration mode will not be switched to avoid frequent switching of the dehydration mode to generate loud noise.

[0117] As another embodiment of the present invention, the type of laundry in the washing device is obtained, and the corresponding slow-spinning mode operation duration and fast-spinning mode operation duration are selected according to the obtained type.

[0118] For example: for cotton and linen clothing: the slow-off mode lasts 3 minutes, and the fast-off mode lasts 2 minutes; for silk clothing, the slow-off mode lasts 4 minutes, and the fast-off mode lasts 1 minute.

[0119] In this embodiment, a dehydration mode corresponding to different types of clothes is set to avoid damage to the clothes during the dehydration process. In addition, when using the washing machine in daily life, the user can adjust the duration of the slow dehydration mode and the fast dehydration mode according to his or her own preferences to meet his or her personalized needs.

[0120] The present invention also discloses a washing device which is controlled by any control method described in the above technical solutions.

[0121] The washing device of the present invention is controlled by the dehydration control method of the present invention. The dehydration mode can be reasonably switched during the dehydration process of the washing device, which not only avoids noise interference to the user, but also improves the dehydration efficiency according to the actual needs of the user.

[0122] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
