Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the present application, the terms of "upper", "lower", "top", "bottom", orientation or positional relationship are used in a manner based on the normal operating position of the washing machine, it being understood that these terms are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered as limiting the present application.

Before describing the embodiments of the present application, it is necessary to analyze the reason why the washing machine in the prior art is difficult to sufficiently wet the laundry by feeding water into the washing machine in the water feeding stage and the detergent in the washing machine is difficult to sufficiently dissolve, and to reasonably analyze the technical solution of the embodiments of the present application.

In the working process of the existing washing machine, water needs to be fed into the washing machine firstly, and then clothes in the washing machine are washed. However, in the water inlet stage, the water outlet direction and the water flow rate of the water flow flowing out of the water inlet pipe are generally fixed, the water outlet direction is single, the water flow rate of the water flow flowing out of the water inlet pipe is not changed, the position of the water flow flowing out of the water inlet pipe falling in the washing machine is generally fixed, the clothes in the washing machine can be soaked at the position, and the detergent in the washing machine can be dissolved at the position. However, since the position where the water flowing out from the water inlet pipe generally falls into the washing machine is fixed, the water flowing out from the water inlet pipe is difficult to fall down to other positions in the washing machine, it is difficult to achieve uniform water inlet in the washing machine, and at other positions in the washing machine, it is difficult for the clothes to be wetted sufficiently, and the detergent is difficult to be dissolved sufficiently.

In view of this, the present application provides a washing machine, which includes a washing machine main body and a workbench assembly. The worktable part is arranged on the washing machine main body.

In one embodiment, the washing machine may be a pulsator washing machine or a drum washing machine.

In one embodiment, the work bench of the pulsator washing machine is generally located above the washing machine main body.

Referring to fig. 1 and 5, the table assembly of the present embodiment includes a table main body 1, a water inlet pipe 2, and a fluid oscillator 3. The table body 1 is formed with a laundry input port 11. The water inlet pipe 2 is provided on the table main body 1. The fluid oscillator 3 is connected to the water outlet end of the water inlet pipe 2, and the water outlet 32 of the fluid oscillator faces the inner side of the clothes input opening 11. In such a structure, the clothes to be washed are put into the washing machine body through the clothes putting port 11 for washing, and in the water inlet stage, the water flowing through the fluid oscillator 3 has an oscillating state, and in the oscillating state, the water outlet direction of the water flowing out from the fluid oscillator 3 can be continuously oscillated and changed. The water outlet 32 of the fluid oscillator faces the inner side of the clothes inlet 11, the water flow flowing through the water inlet pipe 2 is a first water flow, the first water flow changes, the water flow flowing through the fluid oscillator 3 also changes correspondingly, and according to the difference of the water flow flowing through the fluid oscillator 3, the falling position P of the water flowing out of the fluid oscillator 3 in the washing machine main body changes in different distances under the action of gravity. The larger the flow rate of water flowing through the fluidic oscillator 3, the more the water flowing out of the fluidic oscillator 3 is sprayed, and the further the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body is away from the fluidic oscillator 3 in the water outlet direction. The smaller the flow rate of water flowing through the fluidic oscillator 3 is, the closer the water flowing out of the fluidic oscillator 3 is sprayed, and the closer the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body is to the fluidic oscillator 3 in the water outlet direction. Therefore, water can be uniformly supplied into the washing machine body through the fluidic oscillator 3, so that clothes in the washing machine body can be sufficiently wetted, and a detergent in the washing machine body can be sufficiently dissolved.

In one embodiment, referring to fig. 16 to 18, from fig. 16 to 18, the water flow rate increases from 5L/min to 8L/min, the falling position P gradually moves away from the fluidic oscillator 3 along the water outlet direction, and the water flowing out of the fluidic oscillator 3 is in an oscillation state.

It should be noted that, in the normal operation state of the washing machine, the inner side and the outer side of the clothes inlet 11 are not along the gravity direction, and the clothes can usually pass through the clothes inlet 11 and enter the washing machine body through the gravity. The water outlet 32 of the fluidic oscillator faces the inner side of the clothes inlet 11, on one hand, the fluidic oscillator 3 is convenient to supply water into the washing machine body, on the other hand, the water outlet direction of the fluidic oscillator 3 is not along the gravity direction, the water flowing out of the fluidic oscillator 3 falls into the washing machine body under the action of gravity, the larger the water flow flowing through the fluidic oscillator 3 is, the farther the water flowing out of the fluidic oscillator 3 can be sprayed against the gravity, and accordingly, the more and more the falling position P changes.

In one embodiment, the fluidic oscillator 3 is configured to supply water into the washing machine main body.

In one embodiment, the laundry input port 11 is communicated with a laundry washing chamber in the lower washing machine main body.

In one embodiment, the fluidic oscillator 3 is configured to supply water to a laundry washing chamber within the washing machine body. When the clothes are placed in the inner barrel of the washing machine main body for washing, the clothes washing cavity can be an accommodating cavity of the inner barrel. The laundry washing chamber may be a receiving chamber of the pre-wash tub when laundry is placed in the pre-wash tub of the washing machine main body for washing.

In one embodiment, the fluid oscillator 3 is connected to the table main body 1.

In one embodiment, referring to fig. 4, the fluidic oscillator 3 has a main channel 33 and a return channel 34 connected end to end. The return channels 34 are located on two sides of the main channel 33, and the water outlet 32 of the fluid oscillator is communicated with the main channel 33. In such a structure, part of the water at the water outlet end of the main channel 33 flows back to the water inlet end of the main channel 33 through the return channel 34, and interacts with the water at the water inlet end of the main channel 33, so that the water flowing out of the water outlet 32 of the fluidic oscillator oscillates, and the water outlet direction of the fluidic oscillator 3 is changed continuously in the oscillating state.

It should be noted that, in fig. 4, the direction indicated by the arrow R1 and the direction indicated by the arrow R2 are both the water outlet direction of the fluidic oscillator 3, and the direction indicated by the arrow R1 and the direction indicated by the arrow R2 are two boundaries of the water outlet direction of the fluidic oscillator 3, and in the oscillation state, the water outlet direction of the fluidic oscillator 3 gradually changes between the direction indicated by the arrow R1 and the direction indicated by the arrow R2, and the rest of the water outlet direction of the fluidic oscillator 3 is located within an included angle formed by the direction indicated by the arrow R1 and the direction indicated by the arrow R2.

It will be appreciated that the primary channel 33 communicates with the water inlet 31 of the fluidic oscillator.

With such a structure, the water outlet direction of the fluid oscillator 3 will change along the arrangement direction of the main channel 33 and the return channel 34, and the main channel 33 and the return channel 34 are arranged along the circumferential direction of the laundry input opening 11, so that the changing direction of the water outlet direction of the fluid oscillator 3 is more beneficial to the water from the fluid oscillator 3 to be uniformly sprayed into the washing machine main body.

In an embodiment, referring to fig. 1, 5, 8 and 9, the workstation assembly further comprises a regulating device 5 arranged on the water inlet pipe 2, said regulating device 5 being configured to regulate the flow of water through said water inlet pipe 2. With such a structure, the water flow passing through the water inlet pipe 2 can be conveniently adjusted by the adjusting device 5.

In one embodiment, the inlet pipe 2 may not be provided with the adjusting device 5 when the external water source supplying the inlet pipe 2 is originally changed. Specifically, for example, a general household washing machine generally supplies water to the washing machine using tap water as a water source, and a variable pump may be provided in a tap water pipe to adjust the first water flow rate by changing the flow rate of water flowing to the water inlet pipe 2 of the washing machine, so that the washing machine or the table unit does not need to be provided with an additional adjusting device 5 to adjust the first water flow rate.

In one embodiment, referring to fig. 1, 5, 8 and 9, the water inlet pipe 2 includes a main water inlet pipe 21 and a plurality of branch water inlet pipes 22. The regulating device 5 is arranged on the main water inlet pipe 21, and the regulating device 5 is configured to regulate the water flow on the main water inlet pipe 21. Each water inlet branch pipe 22 is correspondingly provided with one fluid oscillator 3, one end of each water inlet branch pipe 22 is connected with the water inlet main pipe 21, and the other end of each water inlet branch pipe 22 is connected with the corresponding fluid oscillator 3. In this configuration, the regulating device 5 is disposed on the main water inlet pipe 21, and the flow rate of water flowing through the fluid oscillator 3 varies with the flow rate of water flowing through the main water inlet pipe 21. The water flow rate flowing through the water inlet main pipe 21 is a first water flow rate, the water flow rate flowing through each fluid oscillator 3 is a second water flow rate, and when the first water flow rate is increased, the second water flow rate is also increased correspondingly; when the first water flow is reduced, the second water flow is correspondingly reduced; while the first water flow rate remains constant, the second water flow rate also remains constant. Therefore, the second water flow rate of the fluidic oscillator 3 in each water inlet branch pipe 22 can be increased, decreased, or maintained in synchronization by adjusting the first water flow rate by the adjusting device 5 provided in the water inlet main pipe 21.

In an embodiment, referring to fig. 3 and 7, one main water inlet pipe 21 is adapted to two branch water inlet pipes 22, each branch water inlet pipe 22 is correspondingly provided with a fluid oscillator 3, and the one main water inlet pipe 21 and the two branch water inlet pipes 22 are connected through a tee joint 4.

With such a structure, the water flowing out of the fluidic oscillator 3 can be sprayed and covered in a wider range in the arrangement direction of the fluidic oscillator 3 through the oscillation change of the water outlet directions of the fluidic oscillators 3 on the same side, which is beneficial to uniform water supply.

It should be explained that, referring to fig. 16 to 18, fig. 16 to 18 show the effect of water flowing out of the fluidic oscillator 3 when at least two fluidic oscillators 3 are located on the same side of the laundry input port 11.

In the figure, the number of the fluid oscillators 3 is two, and the two fluid oscillators 3 are positioned on the same side of the clothes throwing opening 11, so that the water flowing out of the fluid oscillators 3 can be sprayed and covered in a larger range in the arrangement direction of the two fluid oscillators 3 through the change of the water outlet direction, and the uniform water supply is facilitated. Two fluidic oscillators 3 are arranged in the direction indicated by arrow M in the figure.

In one embodiment, referring to fig. 5 to 7, the fluid oscillator 3 is disposed on two opposite sides of the laundry input opening 11. With such a structure, water can be uniformly supplied into the washing machine main body, the maximum falling position P of the water flowing out of the single-side fluid oscillator 3 in the washing machine main body is reduced by about half, accordingly, the water flow flowing through the fluid oscillator 3 can be reduced, and the water can be uniformly supplied into the washing machine main body under the condition that the water flow flowing through the fluid oscillator 3 is small.

It should be explained that, referring to fig. 19 to 21, fig. 19 to 21 show the effect that the fluid oscillator 3 is provided at both opposite sides of the laundry input port 11 and water flows out of the fluid oscillator 3. In fig. 19 to 21, the number of the fluid oscillators 3 is two, and the two fluid oscillators 3 are located on opposite sides of the laundry input port 11. As shown in fig. 21, the water from a single fluidic oscillator 3 can be supplied more uniformly when the maximum falling position P of the water in the washing machine main body reaches approximately the center position between two fluidic oscillators 3, and accordingly the water flow rate through the fluidic oscillator 3 can be reduced, and the water can be supplied more uniformly into the washing machine main body even when the water flow rate through the fluidic oscillator 3 is small.

In one embodiment, the two-sided fluidic oscillators 3 are arranged symmetrically. Thus, the water supply of the fluid oscillator 3 into the washing machine main body is more uniform.

In one embodiment, the number of the fluidic oscillators 3 may be one.

In one embodiment, referring to fig. 8, the adjusting device 5 is a variable flow valve, and the opening of the variable flow valve is configured to be adjusted in a stepless manner or in a stepwise manner. With the structure, the water flow of the water inlet pipe 2 can be regulated steplessly or step by the variable flow valve.

It should be explained that the opening degree of the variable flow valve can be understood as the degree of opening of the variable flow valve, and the water flow of the water inlet pipe 2 can be increased by increasing the opening degree of the variable flow valve, and the water flow of the water inlet pipe 2 can be decreased by decreasing the opening degree of the variable flow valve.

In an embodiment, referring to fig. 8, the variable flow valve may be disposed on the water inlet main pipe 21, and the water flow of the water inlet main pipe 21 may be adjusted steplessly or stepwise by the variable flow valve.

Because the water that the fluidic oscillator 3 flows out under the oscillating state, the play water direction can be the change of vibration constantly, and on same play water direction, because the difference of discharge, the whereabouts position P of the water that the fluidic oscillator 3 flows out in the washing machine main part has the change of far and near again, therefore the water that the fluidic oscillator 3 flows out can spray to the washing machine comparatively uniformly for the clothing in the washing machine can wet comparatively fully, and the detergent in the washing machine can dissolve comparatively fully.

It can be understood that the water flowing out of the fluid oscillator 3 is in an oscillating state, which can accelerate the dissolution of the detergent to some extent.

In one embodiment, adjusting the first amount of water comprises: it is right to adjust through adjusting device 5 first water flow, inlet tube 2 include one intake be responsible for 21 and with intake be responsible for many water inlet branch pipe 22 that 21 connects, every water inlet branch pipe 22 corresponds one of connection fluidic oscillator 3, adjusting device 5 sets up intake be responsible for 21 on, first water flow is for flowing through the water flow of 21 is responsible for in the intake. Thus, the regulating device 5 is arranged on the water inlet main pipe 21, the first water flow is the water flow flowing through the water inlet main pipe 21, the water flow flowing through the fluid oscillator 3 changes along with the change of the first water flow, the water flow flowing through the fluid oscillator 3 is the second water flow, and when the first water flow is increased, the second water flow is also correspondingly increased; when the first water flow is reduced, the second water flow is correspondingly reduced; while the first water flow rate remains constant, the second water flow rate also remains constant. Therefore, the second water flow rate of the fluidic oscillator 3 in each water inlet branch pipe 22 can be increased, decreased, or maintained in synchronization by adjusting the first water flow rate by the adjusting device 5 provided in the water inlet main pipe 21.

In one embodiment, the adjusting device 5 adjusts the first water flow rate, including: the first water flow rate is periodically regulated by the regulating device 5. Thus, by periodically adjusting the first water flow rate, the first water flow rate is repeatedly and periodically changed within a certain flow rate range, the corresponding water flowing through the fluidic oscillator 3 is repeatedly and periodically changed along with the change of the first water flow rate, and the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body is repeatedly and periodically changed from far to near or from near to far, so that the water supply of the fluidic oscillator 3 to the washing machine main body is relatively uniform.

In one embodiment, periodically regulating the first water flow rate by the regulating device comprises: in each of the regulation periods, the first water flow rate is regulated from a starting flow rate to the starting flow rate by the regulating device 5. Thus, during each regulation cycle, the first water flow rate is varied from the initial flow rate and finally regulated back to the initial flow rate. The falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body is adjusted to other falling positions P from the falling position P corresponding to the initial flow, and then the water returns to the falling position P corresponding to the initial flow again, so that the water flowing out of the fluidic oscillator 3 can be sprayed uniformly in one adjusting period.

In one embodiment, the adjusting the first water flow from the initial flow to the initial flow by the adjusting device 5 in each adjusting period includes: the first water flow is increased from the starting flow to a maximum target flow by the regulating device 5. The first water flow is reduced from the maximum target flow to the starting flow by the regulating device 5. Wherein the initial flow rate is a minimum target flow rate. In this way, the first water flow is steplessly regulated from the minimum target flow back to the minimum target flow in one regulation cycle by one stepless increment and one stepless decrement. The stepless increment and stepless decrement are less times in one regulation period. When one adjusting period is finished, the first water flow is at the minimum target flow, if the water supply is required to be stopped, the flow difference between the minimum target flow and 0L/min of the stopped water supply of the first water flow is small, the water supply is favorably and quickly stopped, and the impact on the water inlet pipe 2 caused by the flow difference is reduced as much as possible.

It should be explained that the maximum target flow rate and the minimum target flow rate are set according to actual needs. The maximum target flow and the minimum target flow are boundary flows for adjusting the first water flow, and the first water flow is changed between the minimum target flow and the maximum target flow in the process of adjusting the first water flow by the water supply control method of the embodiment of the application. The first water flow rate may be a maximum target flow rate or a minimum target flow rate.

In one embodiment, the first water flow is adjusted steplessly by the adjusting means 5 from a starting flow, which is the maximum target flow, to the minimum target flow during each adjustment cycle.

In one embodiment, in the stepless adjustment process, the first oscillation time period is a time period during which the water flowing out of the fluid oscillator 3 is in an oscillation state, and the first oscillation time period is at least one adjustment period. Thus, when the first water flow is regulated steplessly to enable the water flowing out of the fluid oscillator 3 to generate an oscillation state, the water flowing out of the fluid oscillator 3 is kept in the oscillation state for at least one regulation period, and the falling position P of the water flowing out of the fluid oscillator 3 in the oscillation state in the washing machine main body can be changed in a near-far mode for at least one regulation period, so that the fluid oscillator 3 supplies water to the washing machine main body more uniformly.

It is understood that, in the stepless adjustment process, the first oscillation time period may be a time period from the start of the water supply to the water inlet main pipe 21 to the occurrence of the oscillation state of the water flowing out of the fluidic oscillator 3.

In the process of stepless regulation, the water flow passing through the fluid oscillator 3 needs to reach a certain value and can oscillate well only after a certain time above the corresponding value. In view of this, in one embodiment, the first water flow rate is configured such that the second water flow rate is not less than 2.3L/min, which is the water flow rate through each fluidic oscillator 3, and the total water supply time period is not less than 6 seconds. In this way, the water flowing out of the fluidic oscillator 3 can be oscillated well. The total water supply time is not less than 6 seconds, so that enough time is ensured for starting oscillation and oscillating for a period of time.

In one embodiment, the conditioning period may be no less than 5 seconds.

In one embodiment, the adjustment period may be 5 seconds, 6 seconds, 7 seconds, 8 seconds, 80 seconds, 150 seconds, or the like.

In an embodiment, for the pulsator washing machine with a minimum water inlet level of about 15L, when the first water flow rate is 5L/min, the water inlet time is 180 seconds, and the adjustment period may be 180 seconds at most.

In an embodiment, for a pulsator washing machine with a minimum water inlet level of about 25L, when the first water flow rate is 5L/min, the water inlet time is 300 seconds, and the adjustment period may be 300 seconds at most.

In one embodiment, the first water flow rate is configured such that the rate of change over time of a second water flow rate, which is the water flow rate through each fluidic oscillator 3, does not exceed 20L/min · s. Thus, when the first water flow reaches a water flow rate that enables water flowing through the fluidic oscillator 3 to have an oscillation state, and the water flowing out of the fluidic oscillator 3 oscillates, the water flowing out of the fluidic oscillator 3 can be in a continuous and stable oscillation state, and cannot be switched from the oscillation state to a non-oscillation state.

With Q₁For minimum target flow, with Q_nThe general flow of water supply to the washing machine main body by stepless regulation of the first water flow rate for the maximum target flow rate with T as a regulation period is as follows.

Referring to fig. 8 and 10, the adjusting device 5 is a variable flow valve, and the opening degree of the variable flow valve is configured to be steplessly adjusted. The inlet valve is opened to supply water to the inlet main pipe 21, and the variable flow valve steplessly adjusts the first water flow in an adjusting period to ensure that the first water flow is enabled to be from the minimum target flow Q₁Stepless increment to maximum target flow Q_nThen from the maximum target flow rate Q_nStepless reduction to minimum target flow Q₁. When the first water flow is the minimum target flow Q₁When the water level in the washing machine main body is not less than the preset water level, the water supply to the water inlet main pipe 21 is stopped, and the water supply is finished. When the first water flow is the minimum target flow Q₁And the water level in the main body of the washing machine is smaller than the preset water level, the first water flow is subjected to stepless regulation for one regulation period through the variable flow valve, and the water flow is circulated repeatedly until the water level in the main body of the washing machine is not smaller than the preset water level.

Referring to fig. 8 and 11, the minimum target flow rate Q₁Is 5L/min, and the maximum target flow rate Q_nIs 8L/min. Concrete water supplyThe flow rate is the same as in fig. 10.

Fig. 16 to 18 each show a state in which the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body gradually moves away from the fluidic oscillator 3 in the process of the first water flow rate being steplessly adjusted from 5L/min to 8L/min.

Fig. 19 to 21 each show a state in which the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body gradually moves away from the fluidic oscillator 3 in the process of the first water flow rate being steplessly adjusted from 5L/min to 8L/min.

In one embodiment, the first water flow rate may be adjusted in a stepwise manner.

In one embodiment, the adjusting device 5 adjusts the first water flow rate, including: the first water flow is adjusted step by the adjusting device 5.

It should be explained that the first water flow rate of each stage is constant for a certain time during the stage-by-stage adjustment process, so as to generate oscillation of the water flowing out of the fluid oscillator.

In one embodiment, the target duration is a preset duration for which each stage of the first water flow rate lasts, and each stage of the first water flow rate and the corresponding preset duration are configured together to make the water flowing out of the fluidic oscillator 3 have an oscillating state. So, through adjusting first water flow step by step, guarantee that the first water flow of each grade and corresponding predetermine long time and can make the water that fluid oscillator 3 flows out have the oscillation state, to the first water flow of each grade, the 3 water direction that fluid oscillator 3 goes out constantly changes under the oscillation state, adjust first water flow step by step and make first water flow change step by step, the corresponding water flow that flows through fluid oscillator 3 changes step by step, the whereabouts position P of the water that fluid oscillator 3 flows out in the washing machine main part therefore produces near-far change, thereby reach the purpose of evenly supplying water in to the washing machine main part.

It is understood that the first water flow rate between two adjacent stages may be sudden change, and when the first water flow rate is suddenly changed from one stage to the adjacent stage, the water flow rate flowing through the fluidic oscillator 3 is also suddenly changed to the corresponding water flow rate, and such sudden change may disturb the oscillation state of the water flowing out of the fluidic oscillator 3, resulting in the water flowing out of the fluidic oscillator 3 being switched from the oscillation state to the non-oscillation state. The duration of the first water flow of each stage reaches the preset duration, so that the first water flow of each stage which can enter the oscillation state originally enters the oscillation state is ensured.

It is understood that the preset time period may include a second attack time period and a second oscillation time period. The second oscillation starting time is the time when the water flowing out of the fluidic oscillator 3 is in a non-oscillation state within the preset time, and the second oscillation time is the time when the water flowing out of the fluidic oscillator 3 is in an oscillation state within the preset time.

In one embodiment, the step-by-step adjustment of the first water flow rate by the adjusting device 5 includes: the first water flow rate is periodically adjusted stepwise by the adjusting device 5.

In one embodiment, the periodic stepwise adjustment of the first water flow rate by the adjustment device 5 comprises:

in each adjusting period, the adjusting device 5 is used for adjusting the first water flow from a preset flow to the initial flow step by step, wherein the preset flow is the first water flow at one level adjacent to the initial flow. In this way, the first water flow rate is adjusted from the first water flow rate of the stage adjacent to the initial flow rate and is adjusted to the initial flow rate step by step through an adjusting period. In one regulation period, the first water flow rate is regulated back to the initial flow rate from the first water flow rate of the stage adjacent to the initial flow rate, and correspondingly, the falling position P of the water flowing out of the fluidic oscillator 3 in the washing machine main body is regulated back to the falling position P corresponding to the initial flow rate from the falling position P corresponding to the first water flow rate of the stage adjacent to the initial flow rate. Therefore, the water from the fluidic oscillator 3 can be sprayed into the washing machine body more uniformly during one conditioning cycle.

In one embodiment, the first water flow rate may be adjusted in a stepwise manner for a plurality of adjustment cycles until the water flow rate in the washing machine main body reaches a preset flow rate.

It can be understood that the water supply to the water inlet main pipe 21 can be stopped as long as the water flow rate in the washing machine main body reaches the preset flow rate, and the water supply does not need to be stopped after a complete regulation period is finished.

In one embodiment, the step-by-step adjustment of the first water flow rate from a preset flow rate to the initial flow rate by the adjusting device 5 in each adjusting period includes: the first water flow is gradually increased from the preset flow to a maximum target flow through the adjusting device 5; gradually decreasing the first water flow from the maximum target flow to the starting flow by the regulating device 5; wherein the initial flow rate is a minimum target flow rate.

In one embodiment, the starting flow may be a flow between the minimum target flow and the maximum target flow. In each regulation period, the step-by-step regulation of the first water flow from a preset flow to the initial flow by the regulation device 5 includes: the first water flow is gradually increased from the preset flow to the maximum target flow by a regulating device 5; the first water flow is gradually decreased from the maximum target flow to the minimum target flow by the adjusting device 5; the first water flow is gradually increased from the minimum target flow to the starting flow by the regulating device 5.

In one embodiment, the initial flow rate may be a maximum target flow rate. In each regulation period, the step-by-step regulation of the first water flow from a preset flow to the initial flow by the regulation device 5 includes: the first water flow is gradually decreased from the preset flow to the minimum target flow through the adjusting device 5; the first water flow is stepped up from the minimum target flow to the maximum flow by the regulating device 5.

In one embodiment, before the reciprocating step-by-step adjustment, the method further comprises: and adjusting the first water flow to the initial flow through the adjusting device 5, and enabling the initial flow to continuously correspond to the preset duration. In this way, the first water flow rate is adjusted from the initial flow rate and adjusted back to the initial flow rate in each adjustment cycle, and the water flowing out of the fluidic oscillator 3 is sprayed more uniformly.

It will be appreciated that the regulating means 5 does not necessarily regulate the first water flow rate stepwise from a preset flow rate to a starting flow rate during each cycle.

In one embodiment, the first water flow rate may be gradually increased from the minimum target flow rate to the maximum target flow rate by the regulating device 5 in each cycle.

In one embodiment, the first water flow rate may be gradually decreased from the maximum target flow rate to the minimum target flow rate by the regulating device 5 during each period.

In an embodiment, the preset time period is a ratio of the adjustment period to the adjustment times of the first water flow rate in each adjustment period, and the adjustment times is twice a value obtained by subtracting 1 from the number of stages of the first water flow rate. Therefore, the preset duration can be reasonably distributed.

It should be explained that the number of stages of the first water flow rate can be understood as the number of different flow rates to which the first water flow rate can be adjusted, and this number of different flow rates does not include 0L/min. For example, the regulating device 5 can regulate the first water flow rate to 3 different flow rates, 5L/min, 6L/min and 8L/min respectively, the three flow rates being unequal, the first water flow rate having a number of stages of 3.

Specifically, n is the number of the first water flow rate, and T is the regulation period. In an adjusting period T, the adjusting times of the first water flow are 2n-2, and the preset time length is T/(2 n-2).

For example, the first water flow rate is 3 stages, the minimum target flow rate is 5L/min, the second stage flow rate is 6L/min, and the maximum target flow rate is 8L/min. In an adjusting period, the first water flow is adjusted to 5L/min from 6L/min to 8L/min and 6L/min, and the adjustment is carried out for 4 times in total, wherein the preset time length is T/4.

In one embodiment, the step-wise adjustment of the first water flow rate may be without periodic regularity.

In one embodiment, the absolute value of the difference between the first water flows of adjacent two stages is equal. Therefore, the falling position P of the fluid oscillator 3 in the washing machine main body is changed more uniformly step by step, which is beneficial to uniformly supplying water to the washing machine main body by the fluid oscillator 3.

In one embodiment, the absolute value of the difference between the first water flow rates of adjacent two stages may not be equal.

In one embodiment, the first water flow rate is configured such that the second water flow rate is not less than 2.3L/min, the second water flow rate is the water flow rate through each of the fluidic oscillators 3, and the preset time period is not less than 2 seconds. In this way, it is ensured that each stage of the first water flow rate can make the water flowing out from the fluid oscillator 3 oscillate well and keep for a certain time in an oscillating state.

In one embodiment, the water flow through each fluidic oscillator 3 is equal.

In one embodiment, the second water flow rate may be 2.3L/min, 2.4L/min, 2.5L/min, 2.6L/min, 3L/min, 4L/min, or 5L/min, among others. Accordingly, the first water flow rate may be 4.6L/min, 4.8L/min, 5L/min, 5.2L/min, 6L/min, 8L/min, or 10L/min.

In one embodiment, the predetermined time period may be 2 seconds, 3 seconds, 5 seconds, 50 seconds, 100 seconds, or T/2.

In one embodiment, the first water flow rate is not less than two stages. Thus, the adjusting device 5 can adjust the first water flow to at least two different flows, the first water flow changes between at least two different flows, the water flow flowing through the fluid oscillator changes between two corresponding different flows, and the falling position P of the water flowing out of the fluid oscillator 3 in the washing machine main body changes far and near, so that the fluid oscillator 3 can supply water to the washing machine main body more uniformly.

In one embodiment, please refer to FIGS. 9 and 12, with Q₁For minimum target flow, with Q₂A first water flow rate of a stage adjacent to the minimum target flow rate, as Q_nT is the adjusting period for the maximum target flow. The adjusting device 5 is at least two constant flow valves arranged on the water inlet main pipe 21, the at least two constant flow valves are connected in parallel, and all the constant flow valves are closed before the first water flow is adjusted. The process of adjusting the first water flow rate is approximately: the water inlet valve is opened to supply water to the main water inlet pipe 21, and the first step is openedA valve flow rate such that the first water flow rate reaches a minimum target flow rate Q₁And make the minimum target flow rate Q₁For a preset duration T/(2 n-2).

Then, the second constant flow valve k is closed₂The first water flow reaches the minimum target flow Q₁To make the minimum target flow rate Q₁For a preset time T/(2 n-2). Then, comparing the water level in the washing machine main body with a preset water level, and stopping supplying water to the water inlet main pipe 21 when the water level in the washing machine main body is not less than the preset water level, and ending the water supply; when the water level in the washing machine main body is less than the preset water level, a second constant flow valve k is opened₂A first water flow rate Q for making the first water flow rate reach a stage adjacent to the minimum target flow rate₂And a first water flow rate Q of a stage adjacent to the minimum target flow rate₂For a preset time period T/(2n-2), whereby a further stepwise adjustment of the first water flow rate for one more adjustment cycle is initiated.
