Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and specifically provides a clothing processing equipment and a control method thereof. Background Art

[0002] Existing clothing processing devices typically rely on a pulsator or washing tub to rotate the clothes for washing, and on the washing tub to spin the clothes at high speed for dehydration. For example, a pulsator washing machine comprises a housing and a washing tub. The housing refers to the fixed portion, such as the outer shell or tub, while the washing tub refers to the rotating inner tub, which performs the washing. Because the housing of a pulsator washing machine is stationary, the clothes often rotate with the rotation of the pulsator or washing tub during the washing or dehydration process. This can occur when the tub is overloaded with clothes, such as when washing large, floating items like down jackets and bed sheets in winter, or when the clothes are unevenly loaded into the clothing processing device. Centrifugal force causes the clothes to protrude from the washing tub and then rub against the inner wall of the housing at high speed, causing significant damage to the clothes.

[0003] Clothes processing devices in the prior art usually have a detection device installed above the washing tub to detect whether the height of the clothes protruding from the washing tub is greater than a threshold value, thereby preventing the clothes from being damaged by friction with the top of the shell when the washing tub rotates. However, since there is also a certain height difference between the shell and the washing tub, when the width of the clothes protruding from the washing tub is large but the height is not higher than the threshold value, the clothes will be damaged by friction with the side wall of the shell during rotation. This situation is particularly common with large and soft clothes such as bed sheets and quilt covers, which cannot be solved by the solutions in the prior art.

[0004] Accordingly, there is a need in the art for a new clothing processing device and a control method thereof to solve the problem that the existing clothing processing devices are easily damaged due to friction between the clothing and the housing during operation. Summary of the Invention

[0010] In the preferred technical solution of the control method of the above-mentioned clothing processing device, the step of "when the clothing width is greater than the preset width, controlling the clothing processing device to stop" further includes: when the clothing width is greater than the preset width, controlling the clothing processing device to enter a balance correction program; reacquiring the clothing width, and when the clothing width is still greater than the preset width, controlling the clothing processing device to stop; wherein, the balance correction program specifically includes: controlling the washing tub to switch back and forth between the steps of forward rotation time T1, stagnation time T2, and reverse rotation time T3, and the value range of T1, T2, and T3 is between 0 and 2 seconds.

[0011] In the preferred technical solution of the control method of the above-mentioned clothing processing device, the step of "when the width of the clothing is greater than the preset width, controlling the clothing processing device to enter the balance correction program" further includes: when the width of the clothing is greater than the preset width, obtaining the material of the clothing; obtaining specific values ​​of T1, T2 and T3 based on the material of the clothing, and correspondingly obtaining the specific switching method of the forward T1 time, stagnation T2 time and reverse T3 time of the balance correction program; controlling the clothing processing device to enter the determined balance correction program.

[0026] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may adjust these embodiments as needed to suit specific applications.

[0027] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for ease of description and are not intended to indicate or imply that the device or component described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the term "mounted" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] like Figures 1 to 3 As shown, in order to solve the problem that clothes are easily damaged by friction with the shell during operation of existing clothes processing equipment, the clothes processing equipment of the present invention includes a shell 1 and a washing tub 2. The washing tub 2 is arranged in the shell 1. The clothes processing equipment also includes at least two distance measuring sensors. The first distance measuring sensor 31 and the second distance measuring sensor 32 are arranged at the clothes inlet of the clothes processing equipment close to the washing tub 2, and are arranged symmetrically with respect to any central plane of the washing tub 2. The central plane is any vertical plane passing through the central axis of the washing tub 2. It should be noted that the present invention does not impose any restrictions on the structure of the shell 1, and technicians can set it according to actual needs. Taking a pulsator washing machine as an example, the shell 1 is the outer barrel 11; for another example, the shell 1 can also be an outer shell, and the washing tub 2 is arranged in the outer shell, as long as the shell 1 can fix the washing tub 2 inside it.

[0030] The advantage of the above-mentioned setting method is that when the clothing processing device of the present invention is working, if the clothing enters the detection range of the first distance measuring sensor 31 and the second distance measuring sensor 32, the first distance measuring sensor 31 can measure the distance L1 between the first distance measuring sensor 31 and the clothing, and the second distance measuring sensor 32 can measure the distance L2 between the second distance measuring sensor 32 and the clothing. The distance L between the first distance measuring sensor 31 and the second distance measuring sensor 32 is set by those skilled in the art and is a fixed value after installation. From this, the width (L-L1-L2) of the clothing that exceeds the height range of the first distance measuring sensor 31 and the second distance measuring sensor 32 can be calculated. When the width of the clothing is within an unacceptable range, the clothing processing device can be controlled to alarm or shut down to prevent the clothing from being damaged by friction with the side wall of the housing 1 when the clothing processing device rotates.

[0031] like Figure 3 As shown, in a possible embodiment, the clothing processing device further includes an infrared sensor 4, which is also arranged at the clothing inlet of the clothing processing device close to the washing tub 2, and the height of the infrared sensor 4 from the clothing inlet is higher than the height of the ranging sensor.

[0032] The advantage of the above-mentioned setting method is that: when washing clothes, when the width of the clothes does not reach the threshold value that triggers the shutdown or alarm of the clothes processing device, but the clothes have reached a certain height above the height range of the distance measuring sensor, which can easily cause the clothes to rub against the shell 1 and be damaged. By arranging the infrared sensor 4 above the distance measuring sensor, it is possible to detect in time whether the clothes exceed the height threshold (that is, the installation height of the infrared sensor 4), thereby timely controlling the clothes processing device to alarm or shut down, and preventing the clothes from rubbing against the top of the shell 1 and causing damage.

[0033] In one possible embodiment, the first ranging sensor 31 or the second ranging sensor 32 is an ultrasonic sensor, a millimeter wave sensor, or a lidar sensor. However, the present invention does not impose any restrictions on the type of ranging sensor; as long as the ranging sensor can measure the distance to the clothing, technicians can set it according to specific circumstances.

[0034] Finally, it should be noted that although the present invention is described using a pulsator washing machine as an example, the clothing processing device of the present invention can obviously also be applied to other devices; for example, a drum washing machine, a sock washing machine, a shoe washing machine, etc.

[0035] In summary, the laundry processing device of the present invention utilizes a distance sensor disposed at the laundry inlet of the washing tub 2 to measure the width of laundry that exceeds the height range of the distance sensor, thereby preventing damage to the laundry caused by friction between the laundry and the housing 1. Furthermore, an infrared sensor 4 is disposed at the laundry inlet of the washing tub 2. When the laundry width is within an acceptable range and the laundry in height direction enters the detection range of the infrared sensor 4, the laundry processing device is promptly controlled to sound an alarm or shut down, thereby preventing damage to the laundry caused by friction between the laundry and the housing 1.

[0036] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0037] For example, in an alternative embodiment, the present invention does not impose any restrictions on the shape of the washing tub 2. As long as the washing tub 2 can wash clothes, these do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0038] For example, in another alternative embodiment, the present invention does not impose any restrictions on the positions of the first ranging sensor 31 and the second ranging sensor 32, as long as the first ranging sensor 31 and the second ranging sensor 32 are located close to the clothing inlet of the washing tub 2 and can measure the width of the clothes; for example, the first ranging sensor 31 and the second ranging sensor 32 can be set on the shell 1 or on the washing tub 2, which does not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

[0039] For example, in another alternative embodiment, the present invention does not impose any restrictions on the position of the infrared sensor 4, as long as the infrared sensor 4 is located close to the clothing inlet of the washing tub 2 and can detect the height of the clothes; for example, the infrared sensor 4 can be set on the shell 1 or on the washing tub 2, which does not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

[0040] In addition, the present invention also provides a control method for a clothes processing device, the structure of which is the same as that described in the above technical solution, such as Figures 1 to 3 As shown, the laundry processing device includes a housing 1 and a washing tub 2, the washing tub 2 being disposed in the housing 1, and the laundry processing device further includes at least two distance measuring sensors, a first distance measuring sensor 31 and a second distance measuring sensor 32 being disposed at a clothing inlet of the laundry processing device near the washing tub 2, and being symmetrically disposed relative to any central plane of the washing tub 2;

[0041] like Figure 4As shown, the control method of the clothes processing device of the present invention includes:

[0042] Step S01: obtaining values ​​of the first ranging sensor and the second ranging sensor;

[0043] Step S02: Calculating the width of the laundry beyond the installation plane where the first and second distance measuring sensors are located and which is perpendicular to the center line of the washing tub;

[0044] Step S03: controlling the laundry processing device to selectively continue normal operation or stop according to the laundry width.

[0045] In step S01, the first distance measuring sensor 31 measures the distance between the first distance measuring sensor 31 and the clothes, and the second distance measuring sensor 32 measures the distance between the second distance measuring sensor 32 and the clothes. The distance between the first distance measuring sensor 31 and the second distance measuring sensor 32 is a fixed value set by a person skilled in the art; for example, the distance between the first distance measuring sensor 31 and the second distance measuring sensor 32 is the diameter of the washing tub 2. Then, step S02 is executed to calculate the width of the clothes that exceeds the installation plane of the first distance measuring sensor 31 and the second distance measuring sensor 32, which is perpendicular to the center line of the washing tub 2. Finally, step S03 is executed to control the clothes processing device to selectively continue normal operation or stop according to the calculated clothes width. It should be noted that the present invention does not impose any restrictions on the frequency of detecting the width of the clothes, and technicians can set it according to actual usage requirements; for example, the width of the clothes can be obtained through continuous detection or intermittent detection.

[0046] like Figure 5 As shown, in a possible implementation, step S03: "controlling the laundry processing device to selectively continue normal operation or stop according to the laundry width" further includes:

[0047] Step S05: When the width of the laundry is greater than the preset width, the laundry processing device is controlled to stop.

[0048] Step S06: Control the clothes processing equipment to alarm;

[0049] Step S07: When the width of the clothes is less than or equal to the preset width, the clothes processing device is controlled to continue normal operation.

[0050] In step S05, when the width of the clothes exceeds the acceptable range, the clothes processing device stops running, and then step S06 is executed to control the clothes processing device to alarm and remind the user to check the running status of the clothes processing device in time.

[0051] like Figure 6As shown, in a possible implementation, a new operating program is first introduced: a balance correction program, wherein the balance correction program specifically includes: controlling the washing tub to switch back and forth between the steps of forward rotation T1 time, stagnation T2 time, and reverse rotation T3 time, and the value range of T1, T2, and T3 is between 0 and 2 seconds.

[0052] Step S05: "When the width of the laundry is greater than the preset width, controlling the laundry processing device to stop" further includes:

[0053] Step S08: When the width of the clothing is greater than the preset width, the material of the clothing is obtained;

[0054] Step S09: obtaining specific values ​​of T1, T2, and T3 based on the material of the clothing, and correspondingly obtaining a specific switching method for the forward rotation time T1, the stagnation time T2, and the reverse rotation time T3 of the balance correction program;

[0055] Step S10: Controlling the clothes processing device to enter the determined balance correction procedure.

[0056] Step S11: reacquire the width of the clothing;

[0057] Step S12: When the width of the laundry is still greater than the preset width, the laundry processing device is controlled to stop.

[0058] In steps S08 to S10, if the width of the laundry is greater than the preset width, indicating that the laundry in the washing tub 2 is unevenly placed or floating on the water surface, causing the width of the laundry beyond the height range of the ranging sensor to exceed the acceptable range, the material of the laundry is obtained, and the running time and running mode of the balance correction program are selected based on the different water absorption properties of different materials. The laundry processing device is then controlled to enter the balance correction program. By controlling the washing tub 2 to switch back and forth between the steps of forward rotation time T1, stagnation time T2, and reverse rotation time T3, the laundry can be evenly placed after rapid forward and reverse rotation or the floating laundry can be immersed in the water; for example, the washing tub 2 is controlled to rotate forward for 0.5 seconds, stagnation time 0.5 seconds, and reverse time 0.5 seconds. The present invention does not impose any restrictions on T1, T2, and T3, and technicians can set them according to actual usage needs. The present invention also does not impose any restrictions on the preset width, and technicians can set it according to actual usage needs; for example, the preset width is 5 cm. Then execute step S11 to regain the width of the clothes, and finally execute S12. When the width of the clothes is still greater than the preset width, it means that the width of the clothes has not been reduced through the balance correction program. At this time, the clothes processing device is controlled to stop, so as to prevent the part of the clothes that exceeds the height of the ranging sensor from rubbing against the shell 1 and being damaged.

[0059] like Figure 3As shown, in a possible embodiment, the clothing processing device further includes an infrared sensor 4, which is also arranged at the clothing inlet of the clothing processing device close to the washing tub 2, and the height of the infrared sensor 4 from the clothing inlet is higher than the height of the ranging sensor.

[0060] In a possible implementation, step S05: "When the width of the laundry is greater than the preset width, controlling the laundry processing device to stop" further includes:

[0061] When either "the width of the laundry is greater than the preset width" or "the height of the laundry exceeds the detection surface of the infrared sensor" is satisfied, the laundry processing device is controlled to stop.

[0062] The infrared sensor 4 is higher than the distance sensor from the clothing inlet. When the width of the clothing is within an acceptable range and the clothing enters the detection range of the infrared sensor 4 in the height direction, or when the width of the clothing exceeds the acceptable range, the clothing treatment device is controlled to stop, thereby preventing the clothing from being damaged by friction with the housing 1. The clothing treatment device protects clothing from both width and height dimensions, providing more comprehensive protection.

[0063] In addition, the present invention also provides a readable storage medium, in which a plurality of program codes are stored. The program codes are suitable for being loaded and run by a processor to execute any of the above-mentioned methods.

[0064] In addition, the present invention also provides a clothing processing device, comprising a processor, wherein the processor is adapted to load and run program codes to execute any one of the methods described above.

[0065] Those skilled in the art will appreciate that the above-mentioned clothing processing device also includes some other well-known structures, such as a processor, a controller, and a memory. The memory includes but is not limited to random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory, or registers, and the processor includes but is not limited to CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. To unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0066] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
