In the description of the embodiments of the present disclosure, unless otherwise specified, "a plurality of" means two or more.

[0012] When describing some embodiments, the terms such as "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense, for example, the term "connected" may refer to fixed connection, and may also refer to detachable connection or integrated connection; and the term may refer to direct connection, and may also refer to indirect connection by means of an intermediate medium. The term "coupled" indicates that two or more components are in direct physical contact or electric contact. The term "coupled" or "communicatively coupled" may also refer to that two or more components are not in direct contact, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this disclosure.

[0013] The expression "at least one of A, B, and C" has the same meaning as the expression "at least one of A, B, or C", and both include the following combinations of A, B, and C: only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, and a combination of A, B, and C.

[0014] The expression "A and / or B" includes the following three combinations: only A, only B, and a combination of A and B.

[0015] The use of the expression "suitable to" or "configured to" herein means open and inclusive language, which does not exclude apparatuses suitable to or configured to perform additional tasks or steps.

[0016] As used herein, the term "about", "roughly", or "approximately" includes a stated value as well as an average value within an acceptable deviation range of a specified value, where the acceptable deviation range is, for example, determined by those of ordinary skill in the art in view of a measurement under discussion and errors related to the measurement of the specific value (that is, the limitation of a measurement system).

[0017] As used herein, the terms "parallel", "perpendicular" and or "equal" include stated conditions as well as conditions similar to the stated conditions, where the similar conditions are within an acceptable deviation range, and the acceptable deviation range is, for example, determined by those of ordinary skill in the art in view of the measurement under discussion and errors related to the measurement of the specific value (that is, the limitation of the measurement system).

[0052] Reference is made to FIG. 4 to FIG. 6. The laundry treatment apparatus 100 further includes a drying device 5, and the drying device 5 is arranged outside the outer tub 2. The drying device 5 is configured to dry the laundry inside the inner tub 3.

[0053] In some embodiments, the drying device 5 includes a shell 50 (an air passage shell). The shell 50 is arranged outside the outer tub 2.

[0054] In some embodiments, the shell 50 includes a first sub-shell.

[0055] The shell 50 further includes a second sub-shell, and the second sub-shell is fixed to an outer circumferential wall of the outer tub 2. The first sub-shell and the second sub-shell may be fixedly connected to each other through screws.

[0056] In some embodiments, the drying device 5 further includes a first passage 51 (a drying air passage), and the first passage 51 is located inside the shell 50. For example, the first passage 51 is located between the first sub-shell and the second sub-shell.

[0060] In some embodiments, a port of the second end of the first passage 51 is inserted into the door seal 41, and the air inside the first passage 51 passes through the door seal 41 and the second opening 31 to enter the inner tub 3. The air inlet 512 of the first passage 51 is close to the rear side of the outer tub 2 away from the door seal 41. Thus, the length of the first passage 51 may be increased, and the length of an air circulation path may be increased, thereby improving the drying effect.

[0061] In some embodiments, the drying device 5 further includes a dryer, and the dryer is configured to dry the air inside the first passage 51. It can be understood that the dryer may include an evaporator and a condenser which are sequentially arranged inside the first passage 51, and the humid and cold air sequentially flows through the evaporator and the condenser to become dry and hot air, which flows back into the second chamber 32 to dry the laundry.

[0063] For example, the fan 852 may guide the air inside the outer tub 2 to flow from the outer tub 2 to the first passage 51, and send the humid air into the dryer. Thus, the fan 852 continuously pumps the humid air inside the outer tub 2 into the dryer to be heated, thereby achieving the purpose of drying the laundry.

[0064] It can be understood that the fan 852 is arranged at a position close to the air inlet 512, thereby accelerating the air circulation, and improving the drying efficiency.

[0065] In some embodiments, the first passage 51 further includes a sixth chamber 511 (a fan chamber), and the fan 852 is arranged inside the sixth chamber 511. The sixth chamber 511 is arranged close to the air outlet 231.

[0066] When the laundry is dried by the laundry treatment apparatus 100, the air inside the inner tub 3 exchanges heat with the laundry to form the hot and humid air, the hot and humid air enters the outer tub 2 and enters the first passage 51 through the air outlet 231, the hot and humid air is dried in the first passage 51 to form dry air, and the dry air flows into the second chamber 32 through the second end of the first passage 51 to exchange heat with the laundry, thereby drying the laundry.

[0067] In some embodiments, the outer tub 2 further includes a second passage 261 (an air outlet passage). The second passage 261 may be in communication with the first chamber 22 through the air return port.

The laundry treatment apparatus 100 further includes a first groove 230 (an air collecting groove), the first groove 230 is arranged on the first wall 23 of the outer tub 2, and the first groove 230 protrudes in a direction away from the first opening 21. One end of the first groove 230 penetrates to the outer circumferential wall of the outer tub 2 to be in communication with the air outlet 231. The second passage 261 may be arranged inside the first groove 230.

[0070] The air inside the outer tub 2 is first gathered by the first groove 230, and then enters the first passage 51 through the air outlet 231. Thus, the concentration of the air is facilitated, the flow rate of the air may be reduced, and the air may gently slow to the air outlet 231, thereby reducing the noise.

[0071] In some embodiments, to improve the drying effect and the drying efficiency, a condensing device may be arranged on one side (that is, the front side) of the first wall 23 close to the first opening 21, and the condensing device is configured to condense the hot and humid air before the hot and humid air enters the first passage 51 or when the hot and humid air enters the first passage 51, thereby cooling and dehumidifying the hot and humid air.

[0133] In some embodiments, the fifth chamber 241 includes a first sub-wall 2411 (a heating chamber rear wall).

[0134] The fifth chamber 241 further includes a second sub-wall 2412 (a heating chamber side wall). The first sub-wall 2411 is connected to a rear end of the second sub-wall 2412.

[0135] The fifth chamber 241 further includes a third sub-wall 2413 (a heating chamber bottom wall). The third sub-wall 2413 is connected to a bottom end of the second sub-wall 2412.

[0136] In some embodiments, the laundry treatment apparatus 100 further includes a sterilization assembly 59, the sterilization assembly 59 is connected to the second sub-wall 2412, and the sterilization assembly 59 is configured to sterilize a liquid inside the first chamber 22.

[0137] In some embodiments, the drying device 5 further includes a heating device 58, the heating device 58 is configured to heat the water inside the fifth chamber 241 to generate water vapor, and the generated water vapor may perform steaming and ironing on the laundry.

[0138] In some embodiments, the heating device 58 is fixedly arranged on the first sub-wall 2411.

[0139] In some embodiments, the laundry treatment apparatus 100 further includes a fifth through hole, the fifth through hole is arranged on the first sub-wall 2411, and the fifth through hole penetrates through the first sub-wall 2411 in the front-back direction of the housing 1. The heating device 58 is fixedly arranged on the first sub-wall through the fifth through hole.

[0140] In some embodiments, the heating device 58 includes a heating portion 581, the heating portion 581 is inserted into the fifth chamber 241, and the heating portion 581 heats the water inside the fifth chamber 241 to generate water vapor.

[0141] In some embodiments, the heating portion 581 may be a heating pipe, and the heating pipe may be bent into several sections.

[0142] In some embodiments, the heating device 58 further includes a fifth fixing member 582 (a heating fixing portion), the fifth fixing member 582 is connected to the heating portion 581, and the fifth fixing member 582 is connected to the first sub-wall 2411. The fifth fixing member 582 may fix the heating device 58 inside the fifth chamber 241.

[0143] In some embodiments, the fifth fixing member 582 is arranged inside the fifth through hole, and the fifth fixing member 582 is connected to the first sub-wall 2411.

[0144] In some embodiments, reference is made to FIG. 19 to FIG. 23, the laundry treatment apparatus 100 further includes a first sensor 7 (a first temperature sensor), the first sensor 7 is arranged inside the fifth chamber 241, and the first sensor 7 is configured to measure a temperature inside the fifth chamber 241.

[0145] In some embodiments, the first sensor 7 may measure the water temperature inside the fifth chamber 241.

[0146] In some embodiments, the laundry treatment apparatus 100 further includes a water blocking portion 6 (a water blocking rib), and the water blocking portion 6 is arranged inside the fifth chamber 241. The water blocking portion 6 is connected to the outer tub 2, and the water blocking portion 6 is located below the first sensor 7 in the height direction of the housing 1.

[0147] When the condensate water flows into the fifth chamber 241 through the third chamber 53, the condensate water flows to the water blocking portion 6, and the water blocking portion 6 prevents the condensate water from flowing to the first sensor 7, thereby separating the condensate water from the first sensor 7, preventing the water temperature of the condensate water from affecting a measurement result of the first sensor 7, and improving the accuracy of date of the first sensor 7.

[0148] In some embodiments, the water blocking portion 6 includes a first surface 61 (a bottom surface), the first sensor 7 is located below the first surface 61, and the first sensor 7 is spaced apart from the first surface 61, thereby preventing the condensate water from making contact with the first sensor 7 when part of the condensate water flows to the first surface 61 of the water blocking portion 6.

[0149] In some embodiments, a plane where the first surface 61 is located is horizontally arranged, thus the condensate water may be prevented from flowing to the first surface 61 of the water blocking portion 6 under the action of gravity, and then the condensate water may be prevented from dripping to the first sensor 7.

[0150] In some embodiments, the water blocking portion 6 further includes a second surface 62 (a top surface), the second surface 62 is arranged in an arc shape, and the arc-shaped second surface 62 may buffer the condensate water flowing to the water blocking portion 6, thereby preventing water splashing caused by intense collision of the condensate water with the water blocking portion 6, preventing the splashed water from being scattered onto the first sensor 7, and improving the accuracy of a measured value of the first sensor 7.

[0151] In some embodiments, the midpoint of the length of the first surface 61 of the water blocking portion 6 in a horizontal direction is defined as a central point of the water blocking portion 6, and a connecting line between the central point of the water blocking portion 6 and a rotational central point of the inner tub 3 is not perpendicular to the plane where the first surface 61 is located. That is, in the height direction of the housing 1, the central point of the water blocking portion 6 is deviated from the rotational central point of the inner tub 3, thereby enlarging the mounting space of the first sensor 7 and the heating device 58, reducing the thickness of the water blocking portion 6, then reducing the size between the bottom of the outer tub 2 and the inner tub 3, that is, reducing the size of the fifth chamber in the height direction, and then reducing the size of the laundry treatment apparatus 100 in the height direction.

[0152] In some embodiments, in a plane perpendicular to the height direction of the housing 1, the projection of the first sensor 7 is spaced apart from the projection of the rotational central point of the inner tub 3. The size between the bottom of the outer tub 2 and the inner tub 3 is limited, so that the first sensor 7 is deviated from the rotational central point of the inner tub 3, thereby enlarging the mounting space of the first sensor 7 and the heating device 58, reducing the thickness of the water blocking portion 6, then reducing the size between the bottom of the outer tub 2 and the inner tub 3, that is, reducing the size of the fifth chamber 241 in the height direction, and then reducing the size of the laundry treatment apparatus 100 in the height direction.

[0153] In some embodiments, the laundry treatment apparatus 100 further includes a second sensor 9 (a second temperature sensor), and the second sensor 9 is arranged inside the sixth chamber 511. The second sensor 9 is configured to measure a temperature of the air inside the sixth chamber 511. The second sensor 9 may penetrate through a chamber wall of the sixth chamber 511. The second sensor 9 includes a probe, the probe is arranged inside the sixth chamber 511, and the probe is configured to measure the temperature.

[0154] In some embodiments, the laundry treatment apparatus 100 further includes a heating assembly, the heating assembly is arranged inside the first passage 51 connected to the sixth chamber 511 and the throwing opening, and the heating assembly is configured to heat the air inside the first passage 51. Under the driving of the fan 852, the air inside the first passage 51 is heated by the heating pipe and then enters the second chamber 32, and takes away the moisture of the laundry inside the second chamber 32 to form the hot and humid air, and the hot and humid air is condensed by the condensing tray 52 and then returns into the sixth chamber 511 through the air outlet 231.

[0155] In some embodiments, the laundry treatment apparatus 100 further includes a third sensor 10 (a third temperature sensor), the third sensor 10 is arranged inside the first passage 51 close to the throwing opening 111, and the third sensor 10 is configured to measure a temperature of the air heated by the heating assembly.

[0156] Thus, the heating assembly may be controlled to be powered on or powered off through the value measured by the third sensor 10, thereby maintaining the required air inlet temperature. If it is determined that the temperature measured by the third sensor 10 is greater than a preset temperature value, the laundry treatment apparatus 100 enters a main drying stage and opens a first valve to inject the condensate water into the third chamber 53.

[0157] In some embodiments, the laundry treatment apparatus 100 further includes a controller 300. The controller 300 may be a chip or a processor. For example, the processor may be a universal central processing unit (CPU), a microprocessor, and an application specific integrated circuit (ASIC). Alternatively, the controller 300 may be a programmable device, including a complex programmable logic device (CPLD), an erasable programmable logic device (EPLD), or a field programmable gate array (FPGA). The chip may be an integrated circuit (IC).

[0158] In some embodiments, the controller 300 is configured to: if the controller 300 receives a first signal, start a drying mode, and determine a corresponding inertia value on the basis of measured weight of the object to be dried inside the second chamber 32.

[0159] The controller 300 may be equipped with a preset algorithm, and the inertia value corresponding to the weight of the object to be dried is calculated on the basis of the preset algorithm.

[0160] The inertia value is a parameter positively correlated with load mass inside the tub. The greater the load mass, the larger the inertia value, and the longer the required drying time Tmax.

[0161] In some embodiments, the control algorithm preset in the controller 300 may also be used to determine a first stop determination parameter Tx, a second stop determination parameter Ty and maximum drying time Tmax on the basis of the inertia value.

[0162] Timing is started when the drying mode is started, and timing time is defined as T.

[0163] When the drying mode is started, the fan 852 is started for operation. When the drying mode is started, the heating assembly is started for operation.

[0164] When the drying mode is started, the third sensor 10 measures a third temperature of the air flowing through the heating assembly, and when the third temperature rises to a preset temperature, the controller 300 controls the first valve to be opened.

[0165] The air passes through the heating assembly to generate hot air, the hot air enters the inner tub 3 to evaporate the moisture in the wet laundry to form the hot and humid air, and the moisture in the hot and humid air is finally condensed and separated out in a water cooling manner inside the condensing device and flows away through the drainage port. The circulating air continuously repeats this process until the laundry is dried.

[0166] In some embodiments, the first sensor 7 is arranged at the bottom of the outer tub 2 and is located between the outer tub 2 and the inner tub 3, and the first sensor 7 is configured to measure a first temperature Ta of the air at the bottom of the outer tub 2.

[0167] The second sensor 9 is arranged inside the first passage 51 close to the air outlet 231, and the second sensor 9 is configured to measure a second temperature Tb of the air flowing back through the air outlet 231.

[0168] In some embodiments, the controller 300 is further configured to: in the drying mode, control the first valve to be opened. When the first valve is opened, the condensate water is injected into the third chamber 53 through the first valve, a difference between the second temperature Tb and the first temperature Ta at the same time point is defined as ΔT, and on the basis of first preset time intervals, values of n ΔT are sequentially taken and are recorded as ΔT 1 , ΔT 2 , ΔT 3 , ..., ΔT n . The first preset time interval may be set as one second.

[0169] A difference ΔTz between the maximum value ΔTmax and the minimum value ΔTmin of the ΔT within a first preset time period is calculated; if it is determined that the difference ΔTz is less than or equal to a preset temperature difference, an average value of the n ΔT within the first preset time period is defined as ΔTn', and a difference ΔTm between the second temperature Tb and the first temperature Ta are sequentially calculated on the basis of second preset time intervals. The first preset time period may be 10 minutes, and the preset temperature difference may be 1.5°C.

[0170] If it is determined that △Tm-△Tn'≥Tx and Tb≥Ty, the drying mode is stopped. Tx is the first stop determination parameter, and Ty is the second stop determination parameter. If it is determined that △Tm-△Tn'>Tx, the difference between the second temperature Tb and the first temperature Ta changes greatly, which indicates that the humidity of the circulating air is low. If Tb≥Ty, it can be further determined that the humidity of the circulating air is low, and the drying mode can be stopped.

[0171] It can be understood that in the later stage of the drying mode, with the increase of the drying degree of the loaded laundry inside the inner tub 3, the heat exchange amount between the circulating air and the load continuously decreases, resulting in gradual rise of the air return temperature of the first passage 51, that is, the second temperature Tb gradually rises. In addition, with the increase of the drying degree of the load, the heat exchange amount between the circulating air and the condensate water also decreases, resulting in gradual decrease of the temperature of the air at the bottom of the outer tub 2, that is, the temperature value of the third sensor 10 gradually decreases during the drying process. The humidity of the circulating air is interpreted through the measured value of the second sensor 9 and the measured value of the third sensor 10, thereby determining the ending of the drying mode.

[0172] In a method for calculating the difference ΔTz between the maximum value ΔTmax and the minimum value ΔTmin of the ΔT within the first preset time period, if it is determined that the difference ΔTz exceeds the preset temperature difference, the difference ΔTm between the second temperature Tb and the first temperature Ta are continuously and sequentially calculated on the basis of the second preset time intervals until △Tm-△Tn'≥Tx and Tb≥Ty, and the drying mode is stopped. Then the difference between the second temperature Tb and the first temperature Ta changes little, and the humidity value of the circulating air inside the laundry treatment apparatus 100 is high. If it is determined that Tb≥Ty, it can be further determined that the humidity of the circulating air is high, thereby avoiding erroneous judgment.

[0173] In some embodiments, the controller 300 is further configured to: start timing when the drying mode is started, define the timing time as T, if it is determined that △Tm-△Tn' < Tx and Tb < Ty, determine whether the T exceeds the Tmax, and when T≥Tmax, stop running the drying mode. Thus, machine damage caused by the excessively long drying time is avoided.

[0174] In some embodiments, the controller 300 is further configured to: in the drying mode, control the first valve to be opened. When the first valve is opened, the condensate water is injected into the third chamber 53 through the first valve, and a difference between the second temperature Tb and the first temperature Ta at the same time point is defined as ΔT.

[0175] The first temperatures Ta and the second temperatures Tb at time points corresponding to seconds are sequentially obtained, and a difference between an average value of the obtained first temperatures Ta and an average value of the obtained second temperatures Tb is defined as Tj. The average value of the m first temperatures Ta within m seconds is taken as Taj, and the average value of the m second temperatures Tb within m seconds is taken as Tbj, and it is defined that Tbj-Taj=△Tj 0 .

[0176] A value of ΔTj at the (m+1)th second is defined as △Tj 1 , a value of ΔTj at the (m+2)th second is defined as △Tj 2 , and so on until a value of ΔTj at the (m+n)th second is defined as △Tj n . ΔTj n is a difference between an average value of (m+n) Tb and an average value of (m+n) Ta within (m+n) seconds.

[0177] Starting from the (m+1)th second, a difference ΔTz between the maximum value ΔTmax and the minimum value ΔTmin of the ΔT within a second preset time period is calculated; if it is determined that the difference ΔTz is less than or equal to a preset temperature difference, an average value of the n ΔT within the second preset time period is defined as ΔTn'; and starting from the (m+n+1)th second, a difference ΔTjx between an average value of the second temperatures and an average value of the first temperatures within (m+n+1) seconds is calculated. The second preset time period may be 10 minutes, and the preset temperature difference may be 1.5°C.

[0178] It can be understood that if it is determined that △Tjx-△Tn'≥Tx and Tb≥Ty, the drying mode is stopped. Tx is the first stop determination parameter, and Ty is the second stop determination parameter. If △Tjx-△Tn'≥Tx, the difference between the second temperature Tb and the first temperature Ta changes greatly, which indicates that the humidity value of the circulating air is low. If it is determined that Tb≥Ty, it can be further determined that the humidity of the circulating air in the laundry treatment apparatus 100 is low, and then the drying mode can be stopped.

[0179] The treatment methods in some embodiments of the present disclosure can correct temperature fluctuations of the second sensor 9 and the third sensor 10 during the drying process, thereby preventing a program from making a drying misjudgment due to abnormal fluctuations of the temperature.

[0180] In some embodiments of the present disclosure, the difference between the second temperature Tb and the first temperature Ta in the drying mode is determined first, a basic value parameter △Tn' is determined, and then the difference between the temperature difference ΔTj and the basic value parameter is continuously compared to judge the drying degree of the laundry. By means of this method, the stop determination accuracy can be improved, and the problem of the laundry being humid or excessively dried under conditions of different load mass, high and low ambient temperatures and different water temperatures can be solved.

[0181] In some embodiments, after drying is started, the temperature values of the second sensor 9 and the third sensor 10 are acquired every 1 s and are continuously acquired for 140 times to obtain T a,1 , T a,2 , T a,3 , ..., T a,140 and T b,1 , T b,2 , T b,3 , ..., T b,140 , arithmetic average values are separately calculated for the temperature values of the first sensor 9 and the temperature values of the second sensor 10 to obtain Taj and Tbj, then the temperature values of the first sensor 9 and the temperature values of the second sensor 10 are acquired every 1 s, the average values are separately calculated again, and then new average values are calculated continuously. This treatment method can correct the temperature fluctuations of the second sensor 9 and the third sensor 10 during the drying process, thereby preventing the program from making the drying misjudgment due to abnormal fluctuations of the temperature.

[0182] In some embodiments, reference is made to FIG. 34, and the laundry treatment apparatus 100 may further include a reinforcing member 81. The reinforcing member 81 may be configured to support the outer tub 2.

[0183] In some embodiments, reference is made to FIG. 34 and FIG. 56, and the laundry treatment apparatus 100 may include a shock absorber 82. The shock absorber 82 may perform shock absorption on the outer tub 2. A top end of the shock absorber 82 may be connected to the outer tub 2 to support the outer tub 2.

[0184] The diameter of the inner tub 3 and the diameter of the outer tub 2 of the traditional laundry treatment apparatus are small, the gap between the outer tub 3 and the housing 1 is large, the overall vibration is relatively low, the reinforcing member is subjected to flanging to form a connecting portion, the shock absorber is connected to the connecting portion formed by flanging, and thus the overall vibration control requirement of the small-diameter outer tub 2 can be met.

[0185] However, under the condition of the enlarged diameter of the outer tub 2, if the original housing, the original reinforcing member and the original connecting portion are still used, the stroke of the shock absorber may be limited. Besides, the original mounting angle of the shock absorber may also affect the shock absorption effect, so that the shock absorption requirement of the laundry treatment apparatus 100 cannot be met.

[0186] In some embodiments, reference is made to FIG. 35 to FIG. 36, and the laundry treatment apparatus 100 may include an adapter 83.

[0187] The adapter 83 may be a member independent of the shock absorber 82. The adapter 83 may be a member separated from the shock absorber 82.

[0188] The adapter 83 may be a member independent of the reinforcing member 81. The adapter 83 may be a member separated from the reinforcing member 81.

[0189] The adapter 83 may be connected to the reinforcing member 81. The adapter 83 may be connected to the shock absorber 82. The adapter 83 may be connected to a bottom end of the shock absorber 82.

[0190] In some embodiments, reference is made to FIG. 34 to FIG. 35, and the reinforcing member 81 may be arranged inside the housing 1. The reinforcing member 81 may be connected to the housing 1. The reinforcing member 81 may be located below the outer tub 2. The reinforcing member 81 may be arranged in the front-back direction of the housing 1.

[0191] The reinforcing member 81 may include a first sub-reinforcing member 8101. In the width direction of the housing 1, the first sub-reinforcing member 8101 may be arranged on one side of the rotational axis of the inner tub 3. The first sub-reinforcing member may be arranged in the front-back direction of the housing 1.

[0192] The reinforcing member 81 may further include a second sub-reinforcing member 8102. In the width direction of the housing 1, the second sub-reinforcing member 8102 may be arranged on one side of the rotational axis of the inner tub 3. The second sub-reinforcing member 8102 may be arranged in the front-back direction of the housing 1.

[0193] The first sub-reinforcing member 8101 and the second sub-reinforcing member 8102 may be arranged opposite to each other. In the width direction of the housing 1, the first sub-reinforcing member 8101 and the second sub-reinforcing member 8102 may be located on two sides side of the rotational axis of the inner tub 3.

[0194] In some embodiments, there may be at least one pair of shock absorbers 82. For example, there may be one pair of shock absorbers 82. There may be two pairs of shock absorbers.

[0195] In some embodiments, the adapter 83 may be arranged on the reinforcing member 81. The adapter 83 may be connected to the reinforcing member 81.

[0196] There may be at least one pair of adapters 83. The number of the adapters 83 may be equal to the number of the shock absorbers 82. The two adapters 83 in pair may be respectively connected to the first sub-reinforcing member 8101 and the second sub-reinforcing member 8102.

[0197] In some embodiments, reference is made to FIG. 37, and the adapter 83 may be provided with a first connecting hole 8321 (a first adapter connecting hole). A second connecting hole 821 (a first shock absorber connecting hole) may be arranged at the bottom end of the shock absorber 82.

[0198] The laundry treatment apparatus 100 may include a first fixing member 841. The first fixing member 841 may be inserted into the first connecting hole 8321 and the second connecting hole 821 to connect the shock absorber 82 to the adapter 83.

[0199] In some embodiments, reference is made to FIG. 38, and an outer diameter of the outer tub 2 may be a first diameter D1.

[0200] A first parameter value < D1. The first parameter value may be 550 mm or 555 mm or 560 mm. The outer diameter of the outer tub is set to be greater than the first parameter value, so that the outer tub 2 may be the large-diameter outer tub 2, thereby facilitating arrangement of the large-diameter inner tub 3, and increasing the accommodating amount of the inner tub 3.

[0201] D1 < a second parameter value. The second parameter value may be 570 mm or 575 mm or 580 mm. The outer diameter of the outer tub 2 is set to be less than the second parameter value, so that the outer diameter of the outer tub 2 may be controlled within a preset range, thereby preventing the housing 1 from being too large due to the excessively large diameter of the outer tub 2, and reducing the overall size of the laundry treatment apparatus 100.

[0202] In some embodiments, reference is made to FIG. 38, and central axes of the first connecting holes 8321 of the two adapters 83 in pair are respectively a first central axis and a second central axis. A distance between the first central axis and the second central axis is a first distance L1.

[0203] A third parameter value < L1. The third parameter value may be 530 mm or 535 mm or 540 mm. The distance between the first central axis and the second central axis is set to be greater than the third parameter value, thereby enlarging a mounting space of the shock absorbers 82, ensuring the stroke of the shock absorbers 82 and the mounting angle of the shock absorbers 82, and preventing the shock absorption ability of the shock absorbers 82 from being affected due to the limited stroke of the shock absorbers 82.

[0204] L1 < a fourth parameter value. The fourth parameter value may be 550 mm or 555 mm or 560 mm. The distance between the first central axis and the second central axis is set to be less than the fourth parameter value, thereby enabling the stroke of the shock absorbers 82 to be within a preset range, increasing the angle of the shock absorbers 82, and preventing the strength of the shock absorbers 82 and the shock absorption ability of the shock absorbers 82 from being affected due to the excessively large stroke of the shock absorbers 82.

[0205] It should be noted that by limiting the first diameter of the outer tub 2, the outer tub 2 is the large-diameter outer tub, which meets the requirement of the user for the washing capacity. By arranging the adapter to connect the reinforcing member 81 to the shock absorber 82, the supporting strength of the bottom end of the shock absorber 82 may be enhanced, the supporting strength of the large-diameter outer tub may be met, and the stability of the bottom end of the shock absorber 82 may be improved. By setting the distance L1 between the first central axis and the second central axis, the movement stroke of the shock absorber 82 may be increased, the mounting angle of the shock absorber 82 may be limited, and the shock absorption requirement of the laundry treatment apparatus 100 may be met.

[0206] In some embodiments, reference is made to FIG. 39 to FIG. 41, and the adapter 83 may include a first adapter plate 831 (an adapter bottom plate).

[0207] The adapter 83 may further include second adapter plates 832 (adapter vertical plates). The second adapter plates 832 may be arranged above the first adapter plate 831. Bottom ends of the second adapter plates 832 may be connected to the first adapter plate 831.

[0208] There may be two second adapter plates 832. The two second adapter plates 832 may be arranged opposite to each other. First connecting holes 8321 may be arranged on the two second adapter plates 832. The first connecting holes 8321 may penetrate through the second adapter plates 832 in thickness directions of the second adapter plates 832. The bottom end of the shock absorber 82 may be located between the two second adapter plates 832.

[0209] Through arrangement of the first adapter plate 831 and the second adapter plates 832, the first connecting holes 8321 are conveniently arranged, and the shock absorber 82 is conveniently connected to the adapter 83.

[0210] In some embodiments, the second adapter plates 832 may be arranged in the width direction of the housing 1. In the width direction of the housing 1, the first connecting hole 8321 may be arranged on one side of the middle portion of the second adapter plate 832 away from the rotational axis of the inner tub 3, thereby facilitating increase of the mounting length of the shock absorber 82.

[0211] In some embodiments, reference is made to FIG. 39 to FIG. 41, and the reinforcing member 81 may be clamped with the adapter 83, thereby facilitating connection of the adapter 83 with the reinforcing member 81.

[0217] In some embodiments, reference is made to FIG. 39 to FIG. 41, and a first connecting portion 8311 (a first connecting structure) configured to be connected to the reinforcing member 81 may be arranged on the first adapter plate 831. Thus, under the condition of high-speed vibration of the entire laundry treatment apparatus 100, the vibration of the outer tub 2 may be prevented from being transferred to the adapter 83 through the shock absorber 82, thereby reducing the abnormal noise in a gap between the adapter 83 and the reinforcing member 81.

[0218] In the front-back direction of the housing 1, the first connecting portion 8311 may be located between the two second adapter plates 832.

[0224] In some embodiments, the third connecting hole 812 is arranged in the vertical direction.

[0225] In some embodiments, in the width direction of the housing 1, the first connecting portion 8311 may be arranged on one side of the center of the first adapter plate 831 close to the rotational axis of the inner tub 3.

[0226] In some embodiments, reference is made to FIG. 39 to FIG. 41, a second connecting portion 8312 (a second connecting structure) configured to be connected to the reinforcing member may be arranged on the first adapter plate 831, and the second connecting portion 8312 may further prevent the vibration of the outer tub 2 from being transferred to the adapter 83 through the shock absorber 82, thereby reducing the noise in the gap between the adapter 83 and the reinforcing member 81.

[0227] In the width direction of the housing 1, the second connecting portion 8312 may be arranged on one side of the first connecting portion 8311 away from the rotational axis of the inner tub 3.

[0236] In some embodiments, a third connecting plate 27 (an outer tub connecting plate) may be arranged on an outer wall of the outer tub 2. A fifth connecting hole 271 (an outer tub connecting hole) is arranged on the third connecting plate 27.

[0237] In some embodiments, a sixth connecting hole 822 (a second shock absorber connecting hole) is arranged at the top end of the shock absorber 82.

[0238] The laundry treatment apparatus 100 further includes a second fixing member 842. The second fixing member 842 is inserted into the fifth connecting hole 271 and the sixth connecting hole 822 to connect the third connecting plate 27 to the shock absorber 82.

[0239] A central axis of the fifth connecting hole 271 may be a third central axis. A distance between the third central axis and the first central axis is a second distance L2. A spacing between the third central axis and the first central axis is may be a third distance L3.

[0240] A fifth parameter value < L2. The fifth parameter value may be 185 mm or 170 mm or 155 mm. Thus, the shock absorption ability of the shock absorber 82 is prevented from being affected due to the excessively small stroke of the shock absorber 82.

[0241] L2 < a sixth parameter value. The sixth parameter value may be 215 mm or 230 mm or 245 mm. Thus, the strength of the shock absorber 82 is prevented from being affected due to the excessively large stroke of the shock absorber 82.

[0242] A ninth parameter value < L3. The ninth parameter value may be 185 mm or 170 mm or 155 mm. Thus, the shock absorption ability of the shock absorber 82 is prevented from being affected due to the excessively small stroke of the shock absorber 82.

[0243] L3 < a tenth parameter value. The tenth parameter value may be 215 mm or 230 mm or 245 mm. Thus, the strength of the shock absorber 82 is prevented from being affected due to the excessively large stroke of the shock absorber 82.

[0244] L3 may be equal to L2.

[0245] In some embodiments, there may be at least two pairs of third connecting plates 27. The number of the third connecting plates 27 may be equal to the number of the shock absorbers 82.

[0246] The top end of the shock absorber 82 may be located between a pair of third connecting plates 27. The fifth connecting hole 271 may be arranged in the front-back direction of the housing 1.

[0247] In some embodiments, a seventh parameter value < L1 / D1. The seventh parameter value may be 0.9 or 0.85 or 0.8. Thus, the minimum value of the distance between the first central axis and the second central axis is limited, thereby ensuring the stroke of the shock absorber 82 and the angle of the shock absorber 82, and preventing the shock absorption ability of the shock absorber 82 from being affected due to the excessively small stroke of the shock absorber 82.

[0248] L1 / D1 < an eighth parameter value. The eighth parameter value may be 1 or 1.05 or 1.1. Thus, the maximum value of the distance between the first central axis and the second central axis is limited, thereby further limiting the stroke of the shock absorber 82 and the angle of the shock absorber 82, and preventing the strength of the shock absorber 82 and the shock absorption ability of the shock absorber 82 from being affected due to the excessively large stroke or excessively small angle of the shock absorber 82.

[0249] The reinforcing member 81 is connected to the shock absorber 82 through the adapter 83, the supporting strength of the bottom end of the shock absorber 82 may be enhanced, the supporting strength of the large-diameter outer tub 2 may be met, and the stability of the shock absorber 82 may be improved. By setting the distance L1 between the first central axis and the second central axis, the movement stroke and the mounting angle of the shock absorber 82 may be increased, and the shock absorption effect of the overall laundry treatment apparatus 100 may be improved.

[0250] In some embodiments, the first fixing member 841 may be clamped with the second adapter plate 832.

[0251] In some embodiments, the second fixing member 842 may be clamped with the third connecting plate 27.

[0252] The laundry treatment apparatus 100 may continuously accumulate the lint during the drying process, the lint is generally accumulated inside the first passage 51 of the drying device 5, at the fan 852 and at the air outlet 231, and if it is not processed timely, the lint may block the first passage 51, which affects the drying efficiency.

[0253] In some embodiments, the laundry treatment apparatus 100 further includes a rinsing member 63. The rinsing member 63 may rinse components such as the air outlet 231 or the fan 852 inside the first passage 51.

[0254] In some embodiments, the rinsing member 63 includes a rinsing portion 630. The rinsing member 63 further includes a first extension portion 631 (a side wall), and the first extension portion 631 surrounds the rinsing portion 630. Thus, the rinsing member 63 forms a cylindrical structure with an open end, and the first extension portion 631 is connected in a sealed manner to the outer circumferential wall of the outer tub 2.

[0255] In some embodiments, the rinsing member 63 includes a third passage 6311 (a flow passing air passage). A first end of the third passage 6311 may be in communication with the second passage 261 through the air outlet 231, and a second end of the third passage 6311 is in communication with the air inlet 512 of the first passage 51.

[0257] In some embodiments, one side of the rinsing portion 630 facing away from the outer circumferential wall of the outer tub 2 is connected in a sealed manner to one end of the first passage 51 provided with the air inlet 512.

[0258] In some embodiments, the laundry treatment apparatus 100 further includes a ventilation hole 635, and the ventilation hole 635 is arranged on the rinsing portion 630. The ventilation hole 635 is arranged corresponding to the air inlet 512 so as to communicate the third passage 6311 with the first passage 51. The air is drawn into the first passage 51 by the fan 852 after passing through the third passage 6311 and the ventilation hole 635.

[0259] It can be understood that the first extension portion 631 is arranged, and the first extension portion 631 is sealed with the outer circumferential wall of the outer tub 2, so that the sealing structure of the rinsing member 63 can be simplified, and air leakage can be prevented. Besides, the first extension portion 631 is in contact with the outer tub 2, and the outer tub 2 provides a supporting force for the first extension portion 631, thereby improving the supporting and fixing effects for the first passage 51.

[0260] In some embodiments, the rinsing member 63 further includes a fourth chamber 6312 (a rinsing chamber), and the fourth chamber 6312 is arranged on the rinsing portion 630.

[0261] In some embodiments, reference is made to FIG. 4, the rinsing member 63 may be connected to the outer tub 2, and the rinsing member 63 may be located at the air outlet 231. The shell 50 of the drying device 5 may be connected to the rinsing member 63.

[0262] Reference is made to FIG. 44 to FIG. 45, the rinsing member 63 may include at least one rinsing port. The at least one rinsing port may be in communication with the fourth chamber 6312.

[0263] In some embodiments, reference is made to FIG. 44 to FIG. 45, and the rinsing member 63 may include a first rinsing port 6321. The first rinsing port 6321 is arranged on the rinsing portion 630, and the first rinsing port 6321 may be in communication with the fourth chamber 6312.

[0264] In some embodiments, the first rinsing port 6321 may face the first passage 51. For example, the first rinsing port 6321 is formed facing the air inlet 512.

[0265] In some embodiments, the first rinsing port 6321 may be arranged inside the third passage 6311. The first rinsing port 6321 may communicate the fourth chamber 6312 with the third passage 6311. Water sprayed from the first rinsing port 6321 may rinse the fan 852.

[0266] At least part of the water inside the fourth chamber 6312 is sprayed from the first rinsing port 6321, and the water sprayed from the first rinsing port 6321 rinses the first passage 51, thereby rinsing the first passage 51, the fan 852 and the like, and ensuring the drying effect of the laundry treatment apparatus 100.

[0267] In some embodiments, the laundry treatment apparatus 100 may include a second valve (a water inlet valve). The second valve is configured to control water intake and water intake stop of the fourth chamber 6312. When the second valve is opened, the first rinsing port 6321 may spray the water. When the second valve is closed, the first rinsing port 6321 may stop spraying the water.

[0268] The fan 852 may rotate to suck the water sprayed from the first rinsing port 6321 into the first passage 51 so as to rinse the fan 852 and the first passage 51, thereby washing down or shaking off the lint on the components such as the first passage 51, the fan 852 and the like, preventing the drying air outlet amount and the drying air outlet temperature from being affected by lint accumulation, and ensuring the drying effect.

[0269] In some embodiments, reference is made to FIG. 44 to FIG. 45, and fan 852 may be arranged on one side of the rinsing member 63 away from the outer tub 2. The fan 852 may be arranged opposite to the rinsing member 63. The first rinsing port 6321 may face the fan 852.

[0270] In some embodiments, the fan 852 may include a blower. The blower may be an impeller. The fan 852 may further include a second motor. The second motor is configured to drive the blower to rotate.

[0271] The laundry treatment apparatus 100 has a rinsing mode, and in the rinsing mode, the fan 852 is configured to rotate to suck the water sprayed from the first rinsing port 6321 into the first passage 51 so as to rinse the interior of the first passage 51.

[0272] It can be understood that the fan 852 may rotate to form a negative pressure inside the first passage 51, thereby sucking the water into the first passage 51 to clean the inner wall of the first passage 51, elements inside the first passage 51, and the fan 852.

[0273] It should be noted that the fan 852 may scatter the water, so that the water sprayed from the first rinsing port 6321 may clean the interior of the first passage 51 in all directions.

[0274] In summary, by arranging the fan 852, the first rinsing port 6321, and the second valve, the first passage 51 may be fully rinsed.

[0275] In some embodiments, reference is made to FIG. 46, the controller 300 is further configured to: if it is determined that a second signal is received, control the rinsing mode to be started; and control the fan 852 to rotate, and control the second valve to be opened and closed alternately, where the second valve is opened and closed alternately for at least two cycles, and in one cycle, the second valve is opened for first preset time, and the second valve is closed for second preset time.

[0276] It can be understood that after receiving a rinsing signal for the first passage 51, the fan 852 is controlled to rotate continuously, and the second valve is controlled to be opened and closed periodically, thereby ensuring the rinsing time to achieve powerful cleaning of the lint, facilitating flowing down of the lint, and saving the water resource.

[0277] In some embodiments, a first parameter value ≤ the first preset time. The first parameter value may be 11 s or 10 s or 9 s. Thus, the first preset time may be prevented from being excessively short, thereby ensuring the rinsing effect.

[0278] The first preset time ≤ a second parameter value. The second parameter value may be 13 s or 14 s or 15 s. Thus, the excessively long overall washing time caused by the excessively long rinsing time caused by the excessively long first preset time is avoided.

[0279] A third parameter value ≤ the second preset time. The third parameter value may be 2 s or 1.5 s or 1 s. Thus, the excessively short rinsing interval time caused by the excessively short second preset time is avoided, the lint flowing down with a water flow is prevented from being affected, the rinsing effect being affected by the excessively short rinsing interval time is avoided, the continuous water intake is avoided, and the resource can be saved.

[0280] The second preset time ≤ a fourth parameter value. The fourth parameter value may be 3.5 s or 4 s or 4.5 s. Thus, the excessively long rinsing interval time caused by the excessively long second preset time is avoided, the proportion of the cycle time occupied by the rinsing interval time is prevented from being too large, and the rinsing effect is prevented from being affected.

[0281] In some embodiments, reference is made to FIG. 47, the controller 300 is further configured to: if it is determined that the second signal is received, control the rinsing mode to be started; and control the second valve to be opened, after the second valve is opened for third preset time, control the fan 852 to rotate, and after the fan 852 rotates for fourth preset time, close the second valve, and enable the fan 852 to rotate for fifth preset time.

[0282] Thus, after receiving the rinsing signal for the first passage 51, the second valve is controlled to operate separately for the third preset time, then the fan 852 is started, and the water flow sprayed within the third preset time achieves the effect of soaking the lint. The second valve and the fan 852 are set to operate simultaneously for the fourth preset time, so that rinsing can be performed to clean the lint. The fan 852 is set to operate separately for the fifth preset time, so that the fan 852 may centrifugally throw out part of the lint, thereby further cleaning the lint.

[0283] In some embodiments, a fifth parameter value ≤ the third preset time. The fifth parameter value may be 9 s or 8 s or 7 s. Thus, the soaking effect being affected by the excessively short soaking time caused by the excessively short third preset time is avoided.

[0284] The third preset time ≤ a sixth parameter value. The sixth parameter value may be 11 s or 12 s or 13 s. Thus, the prolonged overall rinsing time caused by the excessively long soaking time caused by the excessively long third preset time is avoided, and water waste is avoided.

[0285] In some embodiments, a seventh parameter value ≤ the fourth preset time. The seventh parameter value may be 9 s or 8 s or 7 s. Thus, the soaking effect being affected by the excessively short rinsing time caused by the excessively short fourth preset time is avoided.

[0286] The fourth preset time ≤ an eighth parameter value. The eighth parameter value may be 11 s or 12 s or 13 s. Thus, the prolonged overall rinsing time caused by the excessively long rinsing time caused by the excessively long fourth preset time is avoided, and water waste is avoided.

[0287] In some embodiments, a ninth parameter value ≤ the fifth preset time. The ninth parameter value may be 9 s or 8 s or 7 s. Thus, the lint throwing effect being affected by the excessively short lint throwing time caused by the excessively short fifth preset time is avoided.

[0288] The fifth preset time ≤ a tenth parameter value. The tenth parameter value may be 11 s or 12 s or 13 s. Thus, the prolonged overall rinsing time caused by the excessively long lint throwing time caused by the excessively long fifth preset time is avoided.

[0289] In some embodiments, reference is made to FIG. 47, and the controller 300 is further configured to: after the fan 852 rotates for the fifth preset time, enable the second valve to be opened again, and enable the fan 852 to rotate and the second valve to be opened for simultaneous operation for sixth preset time.

[0290] The fan 852 and the second valve are set to operate simultaneously again, so that the lint thrown out by the fan 852 may be rinsed, thereby improving the lint cleaning effect.

[0291] In some embodiments, an eleventh parameter value ≤ the sixth preset time. The eleventh parameter value may be 9 s or 8 s or 7 s. Thus, the lint rinsing effect being affected by the excessively short lint rinsing time caused by the excessively short sixth preset time is avoided.

[0292] The sixth preset time ≤ a twelfth parameter value. The twelfth parameter value may be 11 s or 12 s or 13 s. Thus, the prolonged overall rinsing time caused by the excessively long lint washing time caused by the excessively long sixth preset time is avoided.

[0293] In some embodiments, when the lint inside the first passage 51 is handled, the rotational speed of the fan 852 is greater than or equal to a preset rotational speed. Thus, the fan 852 may suck the water sprayed from the first rinsing port 6321 into the first passage 51, may throw down the lint on the fan 852, and may also blow down the lint attached to the interior of the first passage 51, thereby facilitating cleaning of the lint.

[0294] In some embodiments, after a washing stage of the laundry treatment apparatus 100 ends and before a rinsing stage, the first passage 51 may be rinsed.

[0295] In some embodiments, after the rinsing stage of the laundry treatment apparatus 100 ends and in a dehydration stage, the first passage 51 may be rinsed.

[0296] In some embodiments, reference is made to FIG. 48 to FIG. 55, and the rinsing member 63 may further include a second rinsing port 6331. The second rinsing port 6331 is arranged on the rinsing portion 630, and the second rinsing port 6331 may be in communication with the fourth chamber 6312.

[0297] The second rinsing port 6331 may be formed facing the air outlet 231 or the air return port. If the second valve is opened, water enters the fourth chamber 6312, and the water flows out of the second rinsing port 6331. If the second valve is closed, the second rinsing port 6331 stops discharging the water.

[0298] At least part of the water inside the fourth chamber 6312 is sprayed from the second rinsing port 6331, and the water sprayed from the second rinsing port 6331 rinses the air outlet 231 and the filtering portion 5211.

[0299] The rinsing member 63 is arranged, and the fourth chamber 6312 and the second rinsing port 6331 are arranged on the rinsing member 63, thereby rinsing the air outlet 231 and the filtering portion 5211, preventing the lint from blocking the filtering portion 5211, and ensuring the air outlet effect of the air outlet 231 and the filtering effect of the filtering portion 5211.

[0300] In some embodiments, the laundry treatment apparatus 100 further includes a second groove 26 (a limiting groove), and the second groove 26 is arranged on the outer circumferential wall of the outer tub 2 and is recessed downwards. The bottom of the first extension portion 631 is clamped in the second groove 26, thereby mutually fixing the first extension portion 631 and the rinsing member 63, and sealing the third passage 6311.

[0301] In some embodiments, part of the first extension portion 631 may also be fastened on the outer circumferential wall of the outer tub 2 through screws. Thus, the firmness at the joint between the first extension portion 631 and the outer tub 2 may be improved.

[0302] In some embodiments, reference is made to FIG. 48 to FIG. 55, and the rinsing member 63 may further include a connecting member 632.

[0306] The fourth chamber 6312 is defined by a space between the rinsing tray 633 and the connecting member 632, so that the fourth chamber 6312 is a closed space, which can store the water source.

[0307] It should be noted that the fourth chamber 6312 is formed by two components in an enclosing manner, and the two components can be conveniently and separately formed and then combined into the fourth chamber 6312, which facilitates dismounting and maintenance. Of course, in some embodiments, the fourth chamber 6312 may be a chamber formed inside the rinsing portion 630, and the connecting member 632 and the rinsing tray 633 are integrally formed. Thus, mounting is facilitated.

[0400] It can be understood that after the water enters the fourth chamber 6312, the water flow may rinse the impeller of the fan 852 and the first groove 230, thereby rinsing the lint accumulated inside the air inlet 512, the fan 852, the air outlet 231, and the first groove 230. The arrangement of the fourth chamber 6312 enlarges the rinsing range, and thus the water flow may be led out of the rinsing ports in all directions.

[0401] In summary, in some embodiments of the present disclosure, by arranging the fourth chamber 6312 and using the fourth chamber 6312 to enlarge the arrangement zone of the rinsing ports, the rinsing ports facing different objects may be arranged as required, for example, the first rinsing port 6321, the second rinsing port 6331, the third rinsing port 6336, the fourth rinsing port 6337, and the like, and the different positions and different objects inside the laundry treatment apparatus 100 may be rinsed, thereby solving the problem of single rinsing position of the traditional laundry treatment apparatus 100, improving the lint cleaning ability for various positions, avoiding lint accumulation, and improving the drying efficiency.

[0402] In some embodiments, the laundry treatment apparatus 100 may include a measurement device 862.

[0403] The measurement device 862 may be arranged on the outer tub 2. The measurement device may be arranged at the top of the outer tub 2. The measurement device may be located on the front side of the outer tub 2. The measurement device 862 may be configured to measure the vibration displacement and the vibration acceleration of the outer tub 2.

[0404] The measurement device 862 may transmit the vibration displacement and the vibration acceleration to the controller 300 in a serial port communication manner.

[0405] The measurement device 862 may be a three-dimensional (3D) vibration displacement sensor.

[0406] In some embodiments, the controller 300 may be internally equipped with a first vibration displacement A i corresponding to eccentric mass M i , i≥1, and i is a positive integer.

[0407] The mass of an eccentric block inside the inner tub 3 is M i , and during the process of increasing the rotational speed of the inner tub 3 to a first rotational speed, the measured vibration displacement is the first vibration displacement A i . For example, the first rotational speed may be 400 rmp.

[0408] The controller 300 may be internally equipped with a second vibration displacement B i corresponding to the eccentric mass M i ,. The mass of a loaded cloth inside the inner tub 3 is M i , and during the process of increasing the rotational speed of the inner tub 3 to the first rotational speed, the measured vibration displacement is the second vibration displacement B i .

[0409] A thirteenth parameter value < the first rotational speed. The thirteenth parameter value may be 390 rmp or 380 rmp or 370 rmp, thereby avoiding the situation that it is difficult to measure the first vibration displacement and the second vibration displacement due to the excessively low rotational speed.

[0410] The first rotational speed < a fourteenth parameter value. The fourteenth parameter value may be 410 rmp or 420 rmp or 430 rmp, thereby preventing the measurement accuracy of the vibration displacement in a low-speed transient stage from being affected by the excessively high rotational speed, and enabling the vibration displacement in the low-speed transient stage to be corrected more accurately.

[0411] In some embodiments, reference is made to FIG. 57, and the controller 300 is further configured to: after the controller 300 receives a dehydration signal, control the first motor 861 to be started, where the first motor 861 increases the rotational speed of the inner tub 3 to the first rotational speed at first acceleration. During the process of the first motor 861 increasing the rotational speed of the inner tub 3 to the first rotational speed at the first acceleration, the measurement device acquires a vibration displacement of the outer tub 2 and records same as a measured vibration displacement E.

[0412] On the basis of the measured vibration displacement E, the first vibration displacement A i , and the second vibration displacement B i , a corrected vibration displacement E' is obtained, and if it is determined that E ≤ A 1 , E'=E+(A 1 -B 1 ). If it is determined that A i < E ≤ A i+1 , E'=E+(A i -B i ).

[0413] Whether the corrected vibration displacement E' is greater than the maximum vibration displacement limit value is determined, if it is determined that the corrected vibration displacement E' is less than or equal to the maximum vibration displacement limit value, the first motor 861 increases the rotational speed of the inner tub 3 to a rotational speed N. If it is determined that the corrected vibration displacement E' is greater than the maximum vibration displacement limit value, the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3.

[0414] It can be understood that the measured vibration displacement during the process of increasing the rotational speed of the inner tub 3 to the first rotational speed may fluctuate, so that the measured vibration displacement during the process of increasing the rotational speed of the inner tub 3 to the first rotational speed is corrected, the accuracy of the vibration displacement in the low-speed transient stage may be improved, whether the inner tub 3 continues to accelerate for dehydration or performs scattering again may be accurately determined, the success rate of completing dehydration may be increased, and the dehydration time may be shortened.

[0415] In some embodiments, if it is determined that E ≤ A 1 , E'=E+(A 1 -B 1 ). If it is determined that A 1 < E ≤ A 2 , E'=E+(A 2 -B 2 ); if it is determined that A 2 < E ≤ A 3 , E'=E+(A 3 -B 3 ); if it is determined that A 3 < E ≤ A 4 , E'=E+(A 4 -B 4 ); if it is determined that A 4 < E ≤ A 5 , E'=E+(A 5 -B 5 ); if it is determined that A 5 < E ≤ A 6 , E'=E+(A 6 -B 6 ); ...; and if it is determined that A i < E ≤ A i+1 , E'=E+(A i -B i ).

[0416] The eccentric mass is in the unit of g. M i may be any eccentric mass. For example, M 1 =100 g, M 2 =200 g, M 3 =300 g, M 4 =400 g, ..., and M 10 =1000 g.

[0417] In some embodiments, the eccentric mass may be divided into four categories, which are respectively a small load, a medium load, a large load and a super large load.

[0418] The small load may correspond to M 1 , M 2 , and M 3 . The medium load may correspond to M 4 , M 5 , M 6 , M 7 , and M 8 . The large load may correspond to M 9 and M 10 . The super large load may correspond to M 11 and more.

[0419] In some embodiments, the vibration displacement is in the unit of mm.

[0420] In some embodiments, reference is made to FIG. 56, the laundry treatment apparatus 100 further includes an eccentric block 864, and the eccentric block 864 may be arranged inside the inner tub 3. The loaded cloth may be arranged inside the inner tub 3.

[0421] The laundry treatment apparatus 100 further includes a hanging spring 863, and the top of the outer tub 2 may be hung on the housing 1 through the hanging spring 863.

[0422] In some embodiments, reference is made to FIG. 58, the controller 300 may be internally equipped with a vibration displacement limit value C j , j≥1, and j is a positive integer. The larger the value of the j, the larger the vibration displacement limit value C j . The maximum one of the vibration displacement limit value C j may be the maximum vibration displacement limit value. N=n j , and the smaller the value of the j, the larger the n j .

[0423] If it is determined that E' ≤ C 1 , N=n 1 . If it is determined that C j < E' ≤ C j+1 , N=n j+1 . The increased target rotational speed N may be divided into different values, different vibration displacements correspond to the different target rotational speeds, and the larger the vibration displacement, the lower the target rotational speed N. Thus, the vibration noise during dehydration may be reduced, and the reliable operation of the dehydration function may be ensured.

[0424] In some embodiments, the A 1 -A i may be divided into continuous j sections. Each section may have at least one first vibration displacement value. The maximum first vibration displacement value of each section may be the vibration displacement limit value C j of this section. The j may be 3. The vibration displacement limit value C j may be divided into three levels. C 1 =max(A 1 -A 3 ), C 2 =max(A 4 -A 8 ), and C 3 =max(A 9 -A 10 ).

[0425] In some embodiments, reference is made to FIG. 59, and the controller 300 is further configured to: after the first motor 861 increases the rotational speed of the inner tub 3 to the rotational speed N, acquire vibration acceleration of the inner tub 3 at the rotational speed N and record same as measured vibration acceleration F.

[0426] If it is determined that the measured vibration acceleration F is less than or equal to the maximum vibration acceleration limit value, the first motor 861 drives the inner tub 3 to maintain the current rotational speed to operate for first preset rotation time and then reduce the speed to 0, or the first motor 861 decelerates the inner tub 3 to a preset speed range, and the first motor 861 drives the inner tub 3 to maintain the rotational speed after deceleration to operate for second preset rotation time and then reduce the speed to 0.

[0427] If it is determined that the measured vibration acceleration F is greater than the maximum vibration acceleration limit value, the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3. Thus, whether the inner tub 3 can complete dehydration at the current rotational speed may be determined on the basis of the vibration acceleration under the condition of high rotational speed, and when the vibration acceleration is excessively large, the rotational speed may be reduced or scattering may be performed again, thereby ensuring continuous high-speed dehydration, and reducing the vibration noise during high-speed dehydration.

[0428] In some embodiments, after the laundry inside the inner tub 3 is scattered, the controller 300 controls the first motor 861 to be started again, and the first motor 861 increases the rotational speed of the inner tub 3 to the first rotational speed at the first acceleration.

[0429] In some embodiments, the controller 300 may be internally equipped with a vibration acceleration limit value D k , k≥1, and k is a positive integer. The larger the value of the k, the larger the vibration acceleration limit value D k . The maximum one of the vibration acceleration limit value D k is the maximum vibration acceleration limit value.

[0430] In some embodiments, the first motor 861 increases the rotational speed N of the inner tub 3 to n j . Under the condition that the measured vibration acceleration F is less than or equal to the maximum vibration acceleration limit value, if it is determined that F ≤ D k and K ≤ j, the first motor 861 drives the inner tub 3 to maintain the current rotational speed to operate for the first preset rotation time and then reduce the speed to 0. If it is determined that D k < F and j ≤ K, the first motor 861 decelerates the inner tub 3 to a preset speed, and the first motor 861 drives the inner tub 3 to maintain the rotational speed after deceleration to operate for the second preset rotation time and then reduce the speed to 0. Thus, it can be ensured that under different rotational speeds N, the first motor 861 may be reasonably controlled on the basis of the vibration acceleration to adjust the speed, thereby increasing the rotational speed of the inner tub 3 under the condition of reducing the noise, and improving the dehydration efficiency.

[0431] In some embodiments, the first motor 861 increases the rotational speed N of the inner tub 3 to n j , under the conditions that the measured vibration acceleration F is less than or equal to the maximum vibration acceleration limit value, D k < F and j ≤ K, if it is determined that D k+o < F ≤ D k+o+1 , the first motor 861 decelerates the inner tub 3 to a preset speed N'= n k+o+1 , k≥1, k is a positive integer, and o is a natural number. Thus, it may be ensured that the inner tub 3 decelerates to an appropriate rotational speed, the reduction of the dehydration effect due to the excessively high deceleration may be avoided, and the noise generated by the excessively low deceleration may be avoided.

[0432] In some embodiments, the controller 300 may be internally equipped with first vibration acceleration G i corresponding to the eccentric mass M i , i≥1, and i is a positive integer. When the rotational speed of the inner tub 3 is a second rotational speed, the measured vibration acceleration is the first vibration acceleration G i , and the second rotational speed is higher than the first rotational speed.

[0433] The first vibration acceleration corresponding to M 1 -M 10 is G 1 -G 10 . The first vibration acceleration corresponding to M i is G i .

[0434] In some embodiments, the G i -G i may be divided into continuous k sections. Each section may have at least one first vibration acceleration value. The maximum first vibration acceleration value of each section may be the vibration displacement limit value D k of this section. The k may be 3. The vibration displacement limit value D k may be divided into three levels. D 1 =max(G 1 -G 3 ), D 2 =max(G 4 -G 8 ), and D 3 =max(G 9 -G 10 ).

[0435] The rotational speed N of the inner tub 3 may be divided into three levels. For example, the N may be n 1 , n 2 or n 3 . The n 1 , the n 2 and the n 3 are sequentially reduced.

[0436] In some embodiments, the number of the sections into which the A 1 -A i is divided may be equal to the number of the sections into which the Gi-Gi is divided. The numbers of the sections where the first vibration displacement and the first vibration acceleration corresponding to the same eccentric mass M i are located may be equal. Thus, the vibration displacement limit value and the vibration acceleration limit value match each other, and it is ensured that the vibration displacement and the vibration acceleration are determined under the same standard.

[0437] In some embodiments, after the corrected vibration displacement E' is obtained, if it is determined that E' ≤ C 1 , the first motor 861 increases the rotational speed of the inner tub 3 to n 1 . If it is determined that C 1 < E' ≤ C 2 , the first motor 861 increases the rotational speed of the inner tub 3 to n 2 . If it is determined that C 2 < E' ≤ C 3 , the first motor 861 increases the rotational speed of the inner tub 3 to n 3 . If it is determined that C 3 < E', the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3.

[0438] After the first motor 861 increases the rotational speed of the inner tub 3 to n 1 , if it is determined that F ≤ D 1 , the first motor 861 drives the inner tub 3 to maintain the rotational speed n 1 to operate for first maintenance time and then reduce the speed to 0. If it is determined that D 1 < F ≤ D 2 , the first motor 861 drives the inner tub 3 to decelerate to the rotational speed n 2 to operate for the first maintenance time and then reduce the speed to 0. If it is determined that D 2 < F ≤ D 3 , the first motor 861 drives the inner tub 3 to decelerate to the rotational speed n 3 to operate for the first maintenance time and then reduce the speed to 0. If it is determined that D 3 < F, the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3.

[0439] After the first motor 861 increases the rotational speed of the inner tub 3 to n 2 , if it is determined that F ≤ D 2 , the first motor 861 drives the inner tub 3 to maintain the rotational speed n 2 to operate for the first maintenance time and then reduce the speed to 0. If it is determined that D 2 < F ≤ D 3 , the first motor 861 drives the inner tub 3 to decelerate to the rotational speed n 3 to operate for the first maintenance time and then reduce the speed to 0. If it is determined that D 3 < F, the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3.

[0440] After the first motor 861 increases the rotational speed of the inner tub 3 to n 3 , if it is determined that F ≤ D 3 , the first motor 861 drives the inner tub 3 to maintain the rotational speed n 3 to operate for the first maintenance time and then reduce the speed to 0. If it is determined that D 3 < F, the first motor 861 reduces the speed to 0 and scatters the laundry inside the inner tub 3.

[0441] For example, the first maintenance time may be 60 s.

[0442] A fifteenth parameter < the first maintenance time. The fifteenth parameter may be 55 s or 50 s or 45 s. Thus, the dehydration time may be ensured, and the dehydration effect may be improved.

[0443] The first maintenance time < a sixteenth parameter. The fifteenth parameter may be 65 s or 70 s or 75 s. Thus, the reduction of the drying efficiency due to the excessively long dehydration time may be avoided.

[0444] In some embodiments, after the first motor 861 drives the inner tub 3 to operate for the first maintenance time and then reduce the speed to 0, dehydration ends.

[0445] In some embodiments, before the corrected vibration displacement E' is obtained, the level of the load inside the inner tub 3 is determined on the basis of the measured vibration displacement E.

[0446] Some embodiments of the present disclosure further provide a control method for the laundry treatment apparatus 100. Reference is made to FIG. 57.
