AI Technical Summary
Existing pulsator washing machines experience eccentric vibrations during the spin-drying process due to uneven load on the inner tub, which can easily cause the outer tub to collide with the machine body, generating vibration and noise. Existing protective measures are not very effective.
By setting detection points on the side and bottom of the outer tub, sensors are used to detect the distance between the outer tub and the box. Based on the distance difference and preset values, it is determined whether the inner tub should stop rotating, thus preventing the outer tub from colliding with the box.
This effectively prevents the outer tub from impacting the washing machine body, reduces vibration and noise, and improves the operating stability and user experience of the washing machine.

[0039] In addition, it should also be noted that the present application does not limit the arrangement position and number of the second sensor 5 on the bottom of the tub 2, for example, the skilled in the art can arrange the second sensor 5 at the middle position or edge position of the bottom of the tub 2, etc., or can also arrange multiple second sensors 5, etc., such adjustment and change of the specific arrangement position and number of the second sensor 5 on the bottom of the tub 2 does not deviate from the principle and scope of the present application, and should be limited within the protection scope of the present application.
[0040] Preferably, as shown in Figure 1 the side of the tub 2 of the present application is provided with two detection points, and the two detection points are distributed at intervals along the circumference of the tub.
[0041] Preferably, as shown in Figure 1 the detection point on the side of the tub 2 of the present application is arranged close to the bottom edge of the side of the tub 2.
[0042] Specifically, as shown in Figure 1 the side of the tub 2 of the present application is provided with two detection points, and the two detection points are both installed with a first sensor 4, which can detect the distance between the side of the tub 2 and the side wall of the cabinet 1, from Figure 1The two detection points are respectively located at the left and right sides of the edge of the bottom of the outer barrel 2 from the perspective of the arrow A, and the distance between the side of the outer barrel 2 and the side wall of the cabinet 1 can be detected more accurately.
[0043] It should be noted that the number of detection points arranged on the side of the outer barrel is not limited to two, for example, it can also be three or four, etc.
[0044] Preferably, as shown in the drawings, Figure 1 the bottom of the outer barrel 2 of the present application is provided with two detection points, which are referred to as the first detection point and the second detection point, the first detection point is located at the left side of the bottom of the outer barrel, and the second detection point is located at the right side of the bottom of the outer barrel.

[0046] Preferably, as shown in the drawings, Figure 1 the first detection point and the second detection point of the present application are arranged close to the edge of the bottom of the outer barrel 2.
[0047] Exemplarily, as shown in the drawings, Figure 1 from the perspective of the arrow A, the first detection point and the second detection point of the present application are respectively located at the left and right sides of the edge of the bottom of the outer barrel 2, and through such arrangement, the distance between the bottom of the outer barrel 2 and the bottom wall of the cabinet 1 can be detected more accurately. Figure 1
[0048] Preferably, as shown in the drawings, Figure 1 the bottom of the cabinet 1 of the present application is provided with a waterproof plate 3.
[0049] Exemplarily, as shown in the drawings, Figure 1 the waterproof plate 3 of the present application is arranged on the bottom of the cabinet 1 and is arranged close to the inner bottom wall of the cabinet 1, and through the arrangement of the waterproof plate 3, the water splashed during the dehydration process of the clothes treatment equipment can be collected to prevent leakage.
[0050] On the other hand, based on the above-mentioned washing machine, the present application further provides a control method of a washing machine, as shown in the drawings, Figure 2 the control method of the present application comprises the following steps:
[0051] S100: Before the dehydration mode is executed, the distance between the bottom of the outer barrel 2 and the bottom wall of the cabinet 1 is obtained, which is referred to as the second distance L2.
[0052] Exemplarily, as shown in the drawings, Figure 1 As shown, two detection points are symmetrically arranged at the edges of the left and right ends of the bottom of the outer drum 2, and a second sensor 5 is arranged at each of the two detection points to detect the distance between the bottom of the outer drum 2 and the waterproof plate 3, i.e., to detect two second distances L2.
[0053] It should be noted that, in the case where the waterproof plate 3 is not arranged, the second distance L2 is the distance between the bottom of the outer drum and the inner bottom wall of the cabinet.
[0054] S200: Determine whether the dewatering mode can be started according to the second distance L2.
[0055] That is, whether the clothes in the inner drum are overweight and whether the dewatering program can be started are determined according to the two second distances L2 detected by the two detection points of the bottom of the outer drum 2.
[0056] It should be noted that only one detection point can be arranged at the bottom of the outer drum, and in this case, only one second distance L2 is obtained.
[0057] Exemplarily, as shown, Figure 3 Step S200 includes steps S210 to S230.
[0058] S210: Compare the second distance L2 with a third preset value X3.
[0059] Exemplarily, the two second distances L2 are compared first, the minimum value of the two second distances L2 is taken, the third preset value X3 is a preset value of the distance between the bottom of the outer drum 2 and the bottom wall of the cabinet 1 before the dewatering mode is executed, and then the minimum second distance L2 is compared with the third preset value X3.
[0060] S220: If the second distance L2 is greater than the third preset value X3, it is determined that the dewatering mode can be started.
[0061] That is, the controller of the washing machine determines that the minimum value of the detected distance between the bottom of the outer drum 2 and the bottom wall of the cabinet 1 is greater than the preset value of the distance between the bottom of the outer drum 2 and the bottom wall of the cabinet 1, at this time, the clothes in the inner drum that need to be dewatered are not overweight, and the controller of the washing machine will prompt the user that the dewatering mode can be started.
[0062] S230: If the second distance L2 is not greater than the third preset value X3, it is determined that the dewatering mode cannot be started.
[0063] That is to say, the controller of the washing machine determines that the minimum value of the detected distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 is less than or equal to the preset value of the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1, at this time, the inner tub is in an overweight state, forcibly starting the dewatering program will cause the outer tub 2 to hit the cabinet 1, therefore, the controller of the washing machine will prompt the user that the clothes in the inner tub are overweight, and the number of clothes that need to be dewatered needs to be reduced.
[0064] In addition, it also needs to be explained that step S100 is not necessary, that is to say, when the dewatering mode needs to be performed, the dewatering mode can be directly performed, and it is not necessary to determine whether the clothes in the inner tub are overweight through the distance between the bottom of the outer tub and the bottom wall of the cabinet. Of course, the washing machine of the present application preferably determines whether the clothes in the inner tub are overweight through the distance between the bottom of the outer tub and the bottom wall of the cabinet before performing the dewatering mode, and only when it is determined that the clothes in the inner tub are not overweight, the washing machine performs the dewatering mode, so as to be able to more effectively avoid the situation that the outer tub hits the cabinet.
[0065] S300: In the dewatering mode, the distance between the side of the outer tub 2 and the side wall of the cabinet 1 is obtained, which is denoted as a first distance L1.
[0066] Exemplarily, as shown in Figure 2 In the dewatering mode, the high-speed rotation of the inner tub causes the eccentric displacement of the outer tub 2, at this time, the distance L1 between the two detection points of the side of the outer tub 2 and the side wall of the cabinet 1 is obtained, that is, two first distances L1 are obtained.
[0067] It needs to be explained that the number of detection points between the side of the outer tub 2 and the side wall of the cabinet 1 is not fixed, for example, it can also be set to 1 or 3, etc. Such adjustment and change of the specific number of detection points between the side of the outer tub 2 and the side wall of the cabinet 1 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.
[0068] Of course, the present application preferably sets the number of detection points between the side of the outer tub 2 and the side wall of the cabinet 1 to two symmetrically arranged ones, which can save costs and more accurately detect the distance between the side of the outer tub 2 and the side wall of the cabinet 1.
[0069] In addition, it also needs to be explained that the present application does not limit the acquisition interval of the first distance L1, for example, a person skilled in the art can record data once every 1 / r min, or can also record data once every time the inner tub rotates one circle, etc. Such adjustment and change of the specific acquisition interval of the first distance L1 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.
[0070] S400: In the dehydration mode, the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 is obtained.
[0071] Exemplarily, as shown in Figure 2 and Figure 3 shown, in the dehydration mode, the distance between the two detection points of the bottom of the outer tub 2 and the bottom wall of the cabinet 1 is obtained, which are the first bottom distance LB1 and the second bottom distance LB2, respectively.
[0072] It should be noted that the number of detection points between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 is not fixed, for example, it can also be set to 1 or 3, etc. Such adjustment and change of the specific number of detection points between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.
[0073] Of course, the present application preferably sets the number of detection points between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 to two symmetrically arranged, which can more accurately detect the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 while saving costs.
[0074] In addition, it should also be noted that when the waterproof plate 3 is arranged on the bottom wall of the cabinet 1, the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 obtained at this time is the distance between the bottom of the outer tub 2 and the waterproof plate 3.
[0075] It should be further noted that the present application does not limit the acquisition interval of the first bottom distance LB1 and the second bottom distance LB2, for example, the skilled person can record data once every 1 / r min, or can also record data once every revolution of the inner tub, etc. Such adjustment and change of the specific acquisition interval of the first bottom distance LB1 and the second bottom distance LB2 does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.
[0076] S500: According to the first distance L1 and the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1, the inner tub is selectively stopped from rotating.
[0077] That is, according to the obtained two first distances L1, the first bottom distance LB1 and the second bottom distance LB2, it is judged whether to stop the inner tub from rotating.
[0078] Exemplarily, as shown in Figure 3 , step S500 includes steps S510 to S530.
[0079] S510: Calculate the absolute value Δ = |LB1-LB2| of the difference between the first bottom distance LB1 and the second bottom distance LB2, which is the swing value of the outer tub 2 during the dehydration process.
[0080] S520: comparing the first distance L1 with the first preset value X1, comparing the difference value Δ with the second preset value X2, and selectively stopping the rotation of the inner tub according to the comparison result.
[0081] That is, the minimum value of the two first distances L1 is compared with the preset value of the distance between the side of the outer tub 2 and the side wall of the cabinet 1, and the difference value Δ is compared with the preset value of the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1.
[0082] It should be noted that the first distance L1 is compared with the first preset value X1 every time the first distance L1 is obtained, and the difference value Δ between the first bottom distance LB1 and the second bottom distance LB2 is calculated every time the first bottom distance LB1 and the second bottom distance LB2 are obtained, and then the difference value Δ is compared with the second preset value X2.
[0083] S530: if the first distance L1 is not greater than the first preset value X1 or the difference value Δ is greater than the second preset value X2, the rotation of the inner tub is stopped.
[0084] That is, when the first distance L1 is not greater than the first preset value X1, that is, when the distance between the side of the outer tub 2 and the side wall of the cabinet 1 is less than or equal to the preset value of the distance between the side of the outer tub 2 and the side wall of the cabinet 1 during the rotation of the inner tub, the outer tub 2 will hit the cabinet 1 due to vibration eccentricity, thereby causing vibration noise, at this time, the controller of the washing machine controls the inner tub to stop rotating, or when the difference value Δ is not greater than the second preset value X2, that is, when the swing value of the outer tub 2 is greater than the preset value of the swing value of the outer tub 2 during the rotation of the inner tub, the outer tub 2 will swing due to vibration eccentricity, and then hit the cabinet 1, thereby causing vibration noise, at this time, the controller of the washing machine controls the inner tub to stop rotating.
[0085] That is, when one of the first distance L1 not being greater than the first preset value X1 and the difference value Δ being greater than the second preset value X2 occurs, the controller of the washing machine controls the inner tub to stop rotating.
[0086] Preferably, the washing machine of the present application further comprises a controller capable of controlling the washing machine to complete any one of the above control methods.
[0087] It should be noted that the rotation speed of the inner tub of the washing machine is gradually increased, and in the speed-up stage, the eccentricity of the outer tub 2 is small, and as the rotation speed of the inner tub increases, the rotation speed of the inner tub will enter the first speed interval, in which the outer tub 1 will produce a larger horizontal displacement, and as the rotation speed of the inner tub increases, the rotation speed of the inner tub will enter the second speed interval, in which the outer tub 1 will produce a larger vertical displacement, and in the first speed interval and the second speed interval, the eccentricity of the outer tub 2 is serious, which is the main stage of the outer tub 2 hitting the cabinet 1, and the probability of the outer tub 2 hitting the cabinet 1 in other speed intervals is low.
[0088] Therefore, the process of obtaining the distance between the side of the outer tub 2 and the side wall of the cabinet 1 and obtaining the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 can be obtained throughout the whole process from the beginning to the end of the dehydration program, but for program optimization and energy saving, the present application preferably obtains the distance between the side of the outer tub 2 and the side wall of the cabinet 1 in the first speed interval, and obtains the distance between the bottom of the outer tub 2 and the bottom wall of the cabinet 1 in the second speed interval.
[0089] The specific dehydration process of the washing machine is that before the dehydration program is performed after the completion of the laundry washing, the first sensor 4 will first obtain the distance between the bottom of the outer tub 2 and the waterproof plate 3, i.e. the second distance, and transmit it to the controller by telecommunication, the controller selects the minimum value in the second distance and compares it with the third preset value of the distance between the bottom of the outer tub 2 and the waterproof plate 3, if the minimum value in the second distance is greater than the third preset value, it is determined that the dehydration program can be started, and the controller controls the rotation of the inner tub, if the minimum value in the second distance is not greater than the third preset value, it is determined that the dehydration program cannot be started, and the controller will remind the user that the clothes for dehydration are overweight, and need to be reduced, until the weight of the clothes for dehydration reaches the standard of the dehydration program, the controller will prompt the user to perform the dehydration program.
[0090] After the washing machine enters the dehydration program, as the dehydration program proceeds, the high-speed rotation of the inner tub enters the first speed interval, the first sensor 4 will obtain the distance between the side of the outer tub 2 and the side wall of the cabinet 1, i.e. the first distance, and transmit it to the controller by telecommunication, the controller selects the minimum value in the first distance and compares it with the first preset value of the distance between the side of the outer tub 2 and the side wall of the cabinet 1, if the minimum value in the first distance is not greater than the first preset value, it is determined that the outer tub 2 will hit the cabinet 1 due to excessive vibration eccentricity, the controller will stop the rotation of the inner tub and re-water to distribute the load, the system will return to the stage before the dehydration program is performed, and re-determine whether the clothes in the inner tub are overweight, so as to perform the next cycle, otherwise, if the minimum value in the first distance is greater than the first preset value, it means that the vibration eccentricity of the outer tub 2 is too small to make the outer tub 2 hit the cabinet 1, then the controller determines that the dehydration program continues to run, and does not stop the rotation of the inner tub.
[0091] When the high-speed rotation of the inner drum enters the second speed interval, the second sensor 5 acquires the first bottom distance and the second bottom distance between the bottom of the outer drum 2 and the bottom wall of the cabinet 1 and transmits them to the controller, the controller calculates the difference between the first bottom distance and the second bottom distance and compares it with the second preset value of the distance between the bottom of the outer drum 2 and the bottom wall of the cabinet 1, if the difference is greater than the second preset value, it is determined that the outer drum 2 will hit the cabinet 1 due to excessive vibration eccentricity, the controller stops the rotation of the inner drum and re-loads the water to distribute the load, the system returns to the stage before the dehydration program, re-determines whether the clothes in the inner drum are overweight, and thus the next cycle is performed, otherwise, if the difference is not greater than the second preset value, it means that the vibration eccentricity of the outer drum 2 is too small to make the outer drum 2 hit the cabinet 1, then the controller determines that the dehydration program continues to run until the dehydration program ends.
[0092] Those skilled in the art will appreciate that a combination of features of different embodiments implies within the scope of the application and forms different embodiments, although some embodiments described herein include certain features rather than others included in other embodiments. For example, in the claims of the present application, any of the claimed embodiments can be used in any combination.

Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
