Most of the prior art washing machines have only a single tub, and for different types of laundry, the washing machines need to be placed in the same tub for washing. For example, fig. 1 shows a prior art washing machine comprising an outer tub 2 and an inner tub 1 coaxially arranged, wherein a rotatable stirring paddle 3 is arranged in the inner tub 1. When a user uses the washing machine, the objects to be washed are uniformly placed in the inner tub 1, and the washing water is stirred by the rotation of the stirring paddles 3 or the opposite rotation of the stirring paddles 3 and the inner tub 1, so that the washing of the clothes is realized.

However, the existing washing machines are all preset with a minimum washing water level, and the washing machine can be operated to wash laundry only when the water level in the washing tub reaches or exceeds the minimum washing water level. When the user has a washing requirement of only a small laundry, it is also required to feed water into the washing tub to the lowest washing water level. However, the actual amount of water used for washing is generally large relative to the total amount of clothes, which results in waste of water resources when the existing washing machine is used for washing small pieces of clothes individually. Meanwhile, excessive washing water consumption can further cause the problem of larger power consumption.

As shown in fig. 2 to 5, the laundry treating apparatus of the present invention includes:

a washing tub 100;

the stirring device 300 is rotatably arranged in the washing barrel 100, a second washing space B is formed in the stirring device 300 in a hollow mode, and a communication port for conducting the second washing space B and the external space of the stirring device 300 is formed in the stirring device 300;

the plugging device 500 is used for plugging the communication port, so that the second washing space B inside the stirring device 300 can independently hold water.

In the washing process, the blocking device 500 keeps the communication port blocked, and the second washing space B inside the stirring device 300 independently holds water to wash the load therein.

In the above-described aspect, a first washing space a is further formed between the inner wall of the washing tub 100 of the laundry treating apparatus and the stirring device 300, and the first washing space a and the second washing space B inside the stirring device 300 may be communicated through the communication port. The first washing space A can be used for placing a load for washing, so that the function of washing a large load of the clothes treatment equipment is not affected. However, when the user has a small load for cleaning or the required load is low, the second washing space B in the stirring device 300 can be used for independently containing water for cleaning, and the first washing space a does not contain water, so that the purpose of saving the water consumption for cleaning is achieved.

As a preferred embodiment of the present invention, the plugging device 500 includes a plugging mechanism 510, and the plugging mechanism 510 is installed at the communication port on the stirring device 300. When the blocking mechanism 510 blocks the second washing space B communicated with the password and independently holds water, the stirring device 300 can rotate relative to the washing tub 100.

The laundry treating apparatus further includes a pulsator 400 rotatably disposed in the second washing space B, and during washing, the pulsator 400 and/or the stirring device 300 are controlled to rotate to wash the load in the second washing space B.

In the above-mentioned scheme, the blocking mechanism 510 provided on the stirring device 300 blocks the communication port, so that the rotation of the stirring device 300 relative to the washing tub 100 is not affected. During the washing process, one of the stirring device 300 and the pulsator 400 may be flexibly controlled to rotate, or both may be simultaneously but asynchronously rotated, to stir the washing water in the second washing space B, thereby achieving the washing of the load in the second washing space B.

As another preferred embodiment of the present invention, the communication port is provided at the bottom of the stirring device 300, and the plugging device 500 is provided below the stirring device 300. When the blocking device 500 blocks the second washing space B which is communicated with the password and independently holds water, the stirring device 300 is kept stationary relative to the washing tub 100.

The laundry treating apparatus further includes a pulsator 400 rotatably disposed in the second washing space B, and during washing, the stirring device 300 is kept stationary, and the pulsator 400 is controlled to rotate to wash the load in the second washing space B.

In the above-mentioned scheme, the plugging device 500 plugs the communication port from below, realizes that the second washing space B independently holds water, and simultaneously fixes the stirring device 300. During the washing, the washing water is agitated by the rotation of the pulsator 400 in the second washing space B, so that the washing of the load therein can be accomplished.

Example 1

As shown in fig. 2, the laundry treating apparatus according to the present embodiment includes at least a washing tub 100 and a stirring device 300. Wherein, the stirring device 300 is rotatably disposed inside the washing tub 100, and the inside thereof is hollow to form a second washing space B. The stirring device 300 is provided with a communication port for conducting the second washing space B and the external space of the stirring device 300, and the clothes treating apparatus is further provided with a plugging device 500 which can plug the communication port, so that the second washing space B can independently hold water.

During the washing process of the laundry treatment apparatus, the blocking device 500 keeps the communication port of the stirring device 300 blocked, so that the second washing space B inside the stirring device 300 independently holds water, and washes the load inside the second washing space B. At this time, the space of the inside of the tub 100 outside the stirring device 300 does not store water, and the washing water used for washing is entirely contained in the second washing space B.

The user can utilize the clothes treatment device of this implementation to wash the smallclothes load alone, will need abluent smallclothes load to put into second washing space B, and hold water in second washing space B and accomplish the washing to the smallclothes load, compare in the mode that needs the water injection to wash in washing tub 100, can show the water consumption that reduces the washing process, reaches the purpose that saves the washing water consumption.

In this embodiment, a first washing space a is further formed between the outer side of the stirring device 300 and the inner wall of the washing tub 100, and when the user has a large load for washing or the load required for washing is large at a time, the load can be placed in the first washing space a for washing. The provision of the stirring device 300 does not affect the washing function of the washing tub 100 by itself, but also provides the second washing space B in which the small load can be independently washed, thereby expanding the use manner of the laundry treatment apparatus and improving the user experience.

In a further aspect of this embodiment, the plugging device 500 includes a plugging mechanism 510, and the plugging mechanism 510 is mounted at a communication port on the stirring device 300. When the blocking mechanism 510 blocks the second washing space B communicated with the password and independently holds water, the stirring device 300 can rotate relative to the washing tub 100.

During the washing process of the laundry treating apparatus, the blocking mechanism 510 maintains a state of blocking the communication port, so that the second washing space B independently holds water. At the same time, the stirring device 300 is controlled to rotate, water flow stirring is formed in the second washing space B, and the load therein is washed.

Specifically, inside the second washing space B, the washing water flows in the same direction with the rotation of the stirring device 300, but is influenced by inertia, and the flow of the washing water lags behind the rotation of the stirring device 300, so that the agitation of the water flow can be formed in the second washing space B.

Preferably, the inner wall of the second washing space B is provided with a protruding structure, which can stir the washing water in the second washing space B along with the rotation of the stirring device 300, so as to enhance the water flow intensity in the second washing space B, further improve the washing force and improve the washing effect.

More preferably, the inner wall of the second washing space B has a profiling structure by which a concavo-convex undulating structure in the circumferential direction is formed on the inner wall of the second washing space B. The effective stirring of the washing water in the second washing space B can be realized through the profiling structure, and meanwhile, the concave-convex fluctuation formed by the profiling structure is relatively gentle, so that the friction force of the inner wall of the second washing space B to the load in the stirring device 300 in the rotating process can be reduced. In particular, in this embodiment, the second washing space B is mainly used for washing small clothes such as socks, scarves, etc., and has poor wear resistance, and the inner wall of the second washing space B is provided with a profiling structure to agitate the washing water, so as to protect the washed clothes from being worn.

Further, the stirring ribs 301 are disposed on the outer surface of the stirring device 300, so that when the first washing space a is filled with water to be washed, the stirring ribs 301 on the surface of the stirring device 300 can rotate along with the stirring device 300 to stir the washing water in the first washing space a.

Since the rotation of the stirring device 300 is not affected when the blocking mechanism 510 blocks the communication port in this embodiment, the laundry treating apparatus can simultaneously hold water in the first washing space a and the second washing space B, and the stirring device 300 is controlled to rotate to simultaneously stir the washing water in the two washing spaces, but the washing water in the two washing spaces does not circulate. The user can put different types of loads in different washing spaces to wash simultaneously without worrying about the cross contamination between the loads.

In the above-described embodiment, the washing may be performed in either the first washing space a or the second washing space B by the rotation of the stirring device 300. The laundry treatment apparatus may be provided to a user in a variety of different use modes, so that the user may flexibly select according to the use requirement, and at the same time, the control logic of the laundry treatment apparatus itself may not be excessively complicated.

In this embodiment, the drainage function of the second washing space B is realized through the communication port, and after the washing is finished, the plugging device 500 is controlled to open the communication port, so that the water in the second washing space B can be discharged into the washing tub 100 through the communication port, and then be further discharged outwards from the washing tub 100.

Specifically, the control plugging device 500 opens the communication port, and specifically, the control plugging mechanism 510 opens the communication port. To control the plugging mechanism 510, the plugging device 500 of this embodiment further includes a retractable ejector mechanism (not shown).

The communication port is arranged at the bottom of the stirring device 300, and the jacking mechanism is arranged below the stirring device 300. The pushing mechanism extends out to act on the plugging mechanism 510, so that the plugging mechanism 510 opens the communication port, and the stirring device 300 is stationary relative to the washing tub 100. When the jack-up mechanism is retracted and separated from the blocking mechanism 510, the blocking mechanism 510 is reset to a state of blocking the communication port.

In this embodiment, the initial state of the pushing-open mechanism is a retracted state separated from the plugging mechanism 510, and accordingly, the plugging mechanism 510 keeps the communication port on the stirring device 300 plugged in a normal state.

As a detailed version of this embodiment, the plugging mechanism 510 includes at least a valve plug and an elastic member. The valve plug is mounted at the communication port of the stirring device 300 in a vertically reciprocating manner, and the elastic member applies an elastic force to the valve plug so as to maintain the valve plug in sealing contact with the communication port. The jacking mechanism stretches out upwards to be in contact with the valve plug, and pushes the valve plug to move upwards to be separated from the communication port, so that the communication port is opened to realize drainage. The pushing mechanism is retracted downwards, and the valve plug is reset to a position in sealing contact with the communication port under the action of the elastic force of the elastic piece, so that the communication port is plugged again.

Further, the laundry treating apparatus further includes a tub 200 coaxially disposed with the tub 100, outside the tub 100. The washing tub 100 communicates with the tub 200, and a drain pipe 800 is connected to the bottom of the tub 200 for draining water to the outside of the laundry treating apparatus. When water is required to be drained, the jacking mechanism extends upwards, so that the blocking mechanism 510 opens the communication port, water in the second washing space B is drained into the washing tub 100 through the communication port, and then is drained into the water containing tub 200 from the washing tub 100, and finally is drained along the drain pipe 800.

The knock-out mechanism is specifically installed on the tub 200, and acts on the blocking mechanism 510 through the tub bottom of the washing tub 100 when the knock-out mechanism is extended. Since the blocking mechanism 510 is eccentrically disposed at the bottom of the stirring device 300, and thus the knock-out mechanism is also eccentrically disposed with respect to the tub 100, when the knock-out mechanism controls the blocking mechanism 510 to open the communication port, the relative position between the tub 100 and the tub 200 is also fixed, i.e., the tub 100 remains stationary with respect to the tub 200.

In a further aspect of this embodiment, the second washing space B has an opening 302 at an upper side thereof, and the laundry treating apparatus is supplied with water into the second washing space B through the opening 302.

Specifically, the laundry treating apparatus further includes a second water inlet device for generating a jet of water, the jet of water generated by the second water inlet device flowing through the opening 302 into the second washing space B.

Further, the rotation axis of the stirring device 300 coincides with the axis of the washing tub 100, and the opening 302 is provided in a central region of the top surface of the stirring device 300. The second water inlet means includes a nozzle 600 for injecting water flow, the nozzle 600 being disposed above the tub mouth of the washing tub 100 near the outer peripheral region of the tub mouth, and injecting water flow toward the axis of the washing tub 100 to thereby feed water into the second washing space B.

In detail, the nozzle 600 is mounted on the tub mouth of the tub 200, extends above the tub mouth of the tub 100 in the radial direction of the tub 200, and the water outlet of the nozzle 600 is located on the end face of the extended tip. The water flow is sprayed in a horizontal or nearly horizontal direction by the nozzle 600, and by controlling the speed or pressure of the sprayed water flow to be in a proper range, the sprayed water flow can fall into the second washing space B through the opening 302 to achieve water inflow.

In this embodiment, the second washing space B is mainly used for washing small loads such as socks, scarves, etc. Most of small loads are light and thin, and easily float in the water inlet process, so that the small loads cannot be fully soaked, and the washing effect is further affected. The spray water flow is formed through the nozzle 600 and enters the second washing space B through the opening 302, and can directly spray on the surface of the load in the second washing space B, so that the load can be wetted quickly, and the subsequent washing effect on the load is ensured.

In addition to the water inflow, the opening 302 serves to place laundry in the second washing space B by a user and to take out the washed laundry from the second washing space B, which is convenient to operate.

Further, the laundry treating apparatus of the present embodiment may further be provided with a first water inlet device (not shown) for feeding water into the first washing space a, which is directly water-fed into the washing tub 100, similar to the water inlet device in the conventional washing machine. When a user adopts the first washing space A and the second washing space B to wash simultaneously, the clothes treatment equipment can control the first water inlet device and the second water inlet device to be opened simultaneously, so that water is simultaneously fed into the first washing space A and the second washing space B, and the aim of improving water inlet efficiency is fulfilled.

In a further aspect of this embodiment, the top of the stirring device 300 is lower than the height of the tub 100 at the bung, and thus the opening 302 at the top thereof is also lower than the bung of the tub 100. This arrangement prevents the stirring device 300 from occupying a space above the tub 100 on the one hand, and prevents the problem that the splashed water flows fall outside the tub 200 when the water flow in the second washing space B is splashed outwardly from the opening 302 during washing or dehydrating on the other hand.

In a preferred version of this embodiment, the height of the stirring device 300 is higher than the highest water level of the tub 100. Thus, when the first washing space a and the second washing space B simultaneously hold water for washing, even if the first washing space a adopts the highest water level, the washing water in the first washing space a and the second washing space B does not circulate above the stirring device 300, thereby achieving the purpose that a user can sort laundry and simultaneously wash the laundry.

In this embodiment, a transmission system 700 is provided under the tub 200, and is connected to the tub 100 and the stirring device 300, respectively. The transmission system 700 is connected to a driving motor (not shown) which can independently rotate the washing tub 100 and the agitation device 300 through the transmission system 700, respectively. For example, when the second washing space B independently holds water for washing, the stirring device 300 is controlled to rotate independently, or when the first washing space a and the second washing space B are used to wash the load simultaneously, the washing tub 100 and the stirring device 300 are driven to rotate at high speed, respectively, during the dehydration process.

In a further aspect of this embodiment, the cross-sectional area of the second washing space B inside the stirring device 300 in the horizontal direction is significantly smaller than the cross-sectional area of the washing tub 100. Through the proportion design of the two cross-sectional areas, the water containing quantity when the second washing space B reaches the highest water level is smaller than the water containing quantity when the first washing space A reaches the lowest water level.

When the second washing space B independently holds water to perform washing of the small load, the required washing water consumption is smaller than that of the washing tub 100 directly performing washing of the small load even if the highest water level is adopted in the second washing space B, so that the water consumption can be saved when the second washing space B independently holds water to perform washing.

In this embodiment, the diameter of the outer side of the stirring device 300 is gradually reduced from bottom to top, and the distance between the outer circumference of the stirring device 300 and the inner side wall of the washing tub 100 is small at the bottom of the stirring device 300. With the above-described structure of the stirring device 300, the stirring ribs 301 of the surface thereof extend in the radial direction toward the axis of the washing tub 100 from a position near the inner side wall of the washing tub 100 in the bottom region of the washing tub 100, and are bent upward gradually to be extended in the axial direction of the washing tub 100.

When the laundry treating apparatus washes the load simultaneously using the first washing space a and the second washing space B, the stirring device 300 is controlled to be rotated alternately in forward and reverse during the washing, and the washing water is simultaneously stirred by the stirring bar 301 in the peripheral region of the bottom of the washing tub 100 and in the region near the axis of the middle of the washing tub 100 in the first washing space a. Because the directions of the stirring forces applied to the washing water in different areas are not completely the same, the washing machine can drive the load in the first washing space A to rotate along the circumferential direction in the washing barrel 100 along with the water flow, and can drive the load to turn up and down, thereby preventing the mutual winding between the loads and further enhancing the washing effect.

The present embodiment also provides a control method of the laundry treating apparatus, for independently holding water through the second washing space B, and washing the load inside thereof. Specifically, the laundry treating apparatus determines a washing course to be run after starting, and when it is determined that the washing course is a washing course in which the second washing space B independently holds water, it is run according to the flow shown in fig. 3.

Before water starts to enter, the blocking mechanism 510 is in a state of keeping the communication port blocked. The control blocking mechanism 510 is maintained in the current state, and the laundry treating apparatus turns on the second water inlet device to feed water into the second washing space B.

Specifically, in the above-described water inflow process, the jack-up mechanism for controlling the state switching of the blocking mechanism 510 is always kept in the retracted state. The laundry treating apparatus turns on the second water inlet device to spray water outwardly through the nozzle 600, and water is introduced into the second washing space B through the opening 302 to a set water level. After the water inflow is completed, the laundry treating apparatus starts washing the load.

Further, in this embodiment, the water inflow amount of the second water inlet device into the second washing space B is controlled to be smaller than the water inflow amount required for the water in the washing tub 100 to reach the lowest water level. In this way, a sufficient amount of washing water can be contained in the second washing space B for washing the load therein, and the purpose of saving the washing water consumption can be achieved.

In this embodiment, during the washing process, the blocking mechanism 510 keeps blocking the communication port, the second washing space B independently holds water, and no water is stored in the first washing space a. Meanwhile, the stirring device 300 is controlled to rotate positively and negatively alternately to drive the load in the second washing space B to move along with the water flow, so that the cleaning effect is realized.

Further, after the washing is completed, the laundry treating apparatus performs drainage. Specifically, the blocking device 500 is controlled to open the communication port, and water in the second washing space B is discharged into the washing tub 100 through the communication port and is discharged from the washing tub 100.

In detail, the laundry treating apparatus performs the following operations during the draining:

controlling the stirring device 300 to rotate and position, and enabling the plugging mechanism 510 to rotate to the position above the jacking mechanism;

the ejection mechanism is controlled to extend to act on the blocking mechanism 510, so that the blocking mechanism 510 opens a communication port, water in the second washing space B is discharged into the washing tub 100 and then into the water containing tub 200, and is discharged outwards through the drain pipe 800;

after the water discharge is completed, the pushing-up mechanism is controlled to retract downwards and separate from the plugging mechanism 510, and the plugging mechanism 510 is automatically reset to re-plug the communication port of the stirring device 300.

In this embodiment, after the laundry treating apparatus finishes draining, the above operations of the water inlet process, the washing process, and the draining process may be repeated one to more times, thereby rinsing the load in the second washing space B several times. During rinsing, water is also independently contained through the second washing space B. After the end of the draining process of the last rinsing, the laundry treating apparatus dehydrates the load.

In the dehydrating process of the present embodiment, the laundry treating apparatus controls the stirring device 300 to rotate to dehydrate the load in the second washing space B.

Specifically, the laundry treating apparatus controls the stirring device 300 to rotate at a high speed, and the load in the second washing space B is closely attached to the inner sidewall of the second washing space B by the centrifugal force, and is pressed against the inner sidewall to be dehydrated. The water removed flows upward along the inner sidewall of the second washing space B and is thrown out through the opening 302. Alternatively, part of the water removed may flow down along the inner sidewall of the second washing space B to be collected at the bottom of the second washing space B.

Preferably, after the dehydration is completed, the plugging device 500 is controlled to open the communication port again, that is, the stirring device 300 is controlled to be rotated and positioned, the plugging mechanism 510 is rotated above the pushing mechanism, and the pushing mechanism is controlled to extend to open the plugging mechanism 510 to open the communication port, so that the load collected at the bottom of the second washing space B is dehydrated and discharged.

When a user performs washing of a small load using the laundry treating apparatus of the present embodiment, the small load to be washed is first placed in the second washing space B inside the pulsator 300 through the opening 302, and detergent is put into the second washing space B, and then a set washing program may be started to start washing of laundry. It will be appreciated that when the laundry treating apparatus has an automatic putting function, the detergent may be automatically added during the water inflow process, so that the operation of manual addition by the user may be omitted.

After the washing program is started, the laundry treating apparatus starts to supply water into the second washing space B, and starts washing after the water supply reaches a set water level. The laundry treating apparatus automatically operates the washing course until the dehydration is completed, and the washing course is ended. At this time, the user can take out the dehydrated small load from the second washing space B through the opening 302.

In the present embodiment, the agitation device 300 of the laundry treating apparatus has a hollow structure, and the first washing space a formed between the inner wall of the washing tub 100 and the agitation device 300 can be used for washing a large load. And when the user only has the washing demand of smallclothes load, through the shutoff of plugging device 500 intercommunication mouth, can make second washing space B independently hold water, and laundry treatment equipment can utilize second washing space B alone to wash smallclothes load under the condition that does not exist water in first washing space A to can save the water consumption when washing smallclothes load alone.

Example two

As shown in fig. 2, this embodiment is further defined as the first embodiment, and the laundry treating apparatus further includes a pulsator 400 rotatably disposed in the second washing space B.

In the washing process, the stirring force of the water flow can be enhanced by controlling the relative rotation between the pulsator 400 and the stirring device 300, and the washing effect of the load in the second washing space B can be enhanced.

In the embodiment of the present embodiment, the pulsator 400 is disposed at a certain height in the second washing space B, and small laundry or the like placed in the second washing space B is washed in a space above the pulsator 400. And along with the relative rotation generated between the stirring device 300 and the pulsator 400, the washing water in the second washing space B can circulate at the upper and lower sides of the pulsator 400, further enhancing the washing effect on the laundry.

In the embodiment of the present embodiment, the pulsator 400 is disposed at a certain height in the second washing space B, and small laundry or the like placed in the second washing space B is washed in a space above the pulsator 400. And along with the relative rotation generated between the stirring device 300 and the pulsator 400, the washing water in the second washing space B can circulate at the upper and lower sides of the pulsator 400, further enhancing the washing effect on the laundry.

Meanwhile, in the dehydration process, the water part which is separated from the load flows downwards to the lower part of the impeller 400 under the action of gravity, but the load is blocked by the impeller 400 and cannot enter the space below the impeller 400, so that the water separated from the load can be separated from the load as soon as possible, the load cannot be contacted with the separated water after the dehydration is finished, the problem that the load reabsorbs the separated water is solved, and the dehydration rate of the load is ensured.

In this embodiment, the axis of the washing tub 100, the rotation axis of the stirring device 300, and the rotation axis of the pulsator 400 are coincident. The driving system 700 provided under the tub 200 is respectively connected with the tub 100, the stirring device 300, and the pulsator 400, and the driving motor may independently rotate the tub 100, the stirring device 300, and the pulsator 400 through the driving system 700, respectively.

When the laundry treating apparatus of the present embodiment performs load washing by independently holding water in the second washing space B, the water inlet process and the water outlet process of the control method thereof are the same as those of the first embodiment, but the washing process and the dehydrating process are different as follows.

In this embodiment, the blocking mechanism 510 of the blocking device 500 keeps the communication port blocked during the washing of the laundry treating apparatus, and water is independently contained in the second washing space B. At the same time, the stirring device 300 and/or the pulsator 400 are controlled to rotate, and the load in the second washing space B is washed. The rotation control of the stirring device 300 and the pulsator 400 may specifically be performed by the following methods.

In the first scheme, the pulsator 400 is controlled to be stationary in the washing process, and the stirring device 300 rotates in a positive and negative alternate manner independently, so that relative rotation is formed between the stirring device 300 and the pulsator 400, the stirring force of the washing water in the second washing space B is enhanced, and the washing effect is enhanced.

In the second scheme, the stirring device 300 is controlled to keep static in the washing process, and the pulsator 400 independently rotates in a positive and negative alternate manner, so that relative rotation is formed between the stirring device 300 and the pulsator 400, the stirring force of the washing water in the second washing space B is enhanced, and the washing effect is enhanced.

In the third scheme, the stirring device 300 is controlled to rotate in a positive and negative alternating manner in the washing process, and meanwhile, the impeller 400 is also controlled to rotate, but the rotation speed, the direction and the like of the impeller 400 are different from those of the stirring device 300, and the relative rotation can be generated between the stirring device 300 and the impeller 400, so that the purposes of enhancing the stirring force of washing water and enhancing the washing effect are achieved.

In detail, the pulsator 400 may be controlled to always rotate in the opposite direction to the stirring device 300, and the rotation speeds of the pulsator 400 and the stirring device 300 may be the same or different, so that the pulsator 400 may be rotated in the opposite direction.

Alternatively, the pulsator 400 may be controlled to perform the same forward and reverse rotation operation as the stirring device 300, but the rotation operation of the pulsator 400 is delayed from the stirring device 300 by not N/2 rotation cycles. Wherein N is a positive integer, and each positive and negative rotation of the stirring device 300 is recorded as one rotation period.

In the fourth aspect, the stirring device 300 is controlled to rotate in a forward and reverse direction alternately during the washing process, and the pulsator 400 is in a free rotation state along with the water current. The stirring device 300 rotates in a positive-negative alternating manner, so that the water flow in the second washing space B can be driven to flow, and the pulsator 400 rotates freely under the action of the water flow and can be contacted with the load in the second washing space B. The pulsator 400 may rub the load or further drive the load to move in water, thereby enhancing the washing effect. Meanwhile, since the pulsator 400 is in a free state, the acting force on the load is relatively small, and particularly when the small load material in the second washing space B is light and thin or is not wear-resistant, the abrasion of the load can be avoided.

In the above-mentioned scheme, the actions of the stirring device 300 and the pulsator 400 may be interchanged, that is, the pulsator 400 is controlled to rotate alternately in opposite directions during the washing process, and the stirring device 300 is in a state of rotating freely with the water current.

In a preferred embodiment of the present embodiment, the laundry treating apparatus presets a plurality of different washing courses, and the different washing courses correspond to different rotation actions of the pulsator 400 and the stirring device 300 during the washing process. The laundry treating apparatus controls the rotation of the pulsator 400 and the pulsator 300 according to the currently running washing program, that is, controls the rotation of the pulsator 400 and the pulsator 300 using any one of the above-described first to fourth aspects.

For example, different washing procedures correspond to different washing forces, when the load wear resistance placed in the second washing space B is better, or the dirt degree is larger, a larger washing force is needed, and the running washing procedure adopts the scheme three to control the stirring device 300 and the pulsator 400, that is, drive the stirring device 300 and the pulsator 400 to rotate respectively.

When the load placed in the second washing space B is relatively not wear-resistant, a softer washing force is required, and the washing program running at this time can adopt the scheme four to control the stirring device 300 and the pulsator 400, that is, drive the stirring device 300 to rotate, and the pulsator 400 to be in a state of freely rotating along with the water flow, or drive the pulsator 400 to rotate, and the stirring device 300 to be in a state of freely rotating along with the water flow.

In a further aspect of this embodiment, the laundry treating apparatus controls the stirring device 300 and the pulsator 400 to rotate synchronously during the dehydration process, so that dehydration of the load in the second washing space B can be achieved, and friction generated due to relative movement between the load and the pulsator 400 is avoided, thereby preventing abrasion of the load caused by the pulsator 400 during the dehydration process.

In this embodiment, the laundry treatment apparatus is provided with the pulsator 400 in the second washing space B, and in the washing process, different modes can be adopted to control the relative rotation between the stirring device 300 and the pulsator 400, which is beneficial to enhancing the water flow intensity in the second washing space B, further enhancing the washing force, and improving the washing effect on the load.

Example III

As shown in fig. 3, this embodiment is different from the second embodiment in that: the blocking device 500 is arranged below the stirring device 300, and when the blocking device 500 is used for blocking and communicating the password second washing space B to independently hold water, the stirring device 300 is kept stationary relative to the washing tub 100.

Specifically, the communication port is eccentrically disposed at the bottom of the stirring device 300, and the plugging device 500 includes a valve plug that can move telescopically. The valve plug protrudes upwards to contact with the bottom of the stirring device 300, so that the communication port can be plugged, and at this time, the positions of the stirring device 300 and the plugging device 500 are relatively fixed, so that the stirring device 300 is kept stationary relative to the washing tub 100. The valve plug is withdrawn downward to be separated from the communication port, and the communication port is opened, and the stirring device 300 is rotated with respect to the tub 100.

In this embodiment, the initial state of the plugging device 500 is an open state in which the valve plug is retracted downward and separated from the communication port, and correspondingly, the normal state of the communication port on the stirring device 300 is the communication state, so that the first washing space a and the second washing space B are kept conducting in the normal state. When the second washing space B is required to independently hold water for washing, the valve plug of the plugging device 500 is controlled to extend upwards to plug the communication port.

In a further aspect of the present embodiment, the blocking device 500 is mounted on the tub 200, and when the blocking device 500 blocks the communication port, the valve plug passes through the bottom of the tub 100 to be in contact with the stirring device 300. Since the communication port is eccentrically disposed at the bottom of the stirring device 300, and thus the blocking device 500 is also eccentrically disposed with respect to the tub 100, when the blocking device 500 blocks the communication port, the relative positions of the stirring device 300, the tub 100 and the tub 200 are fixed. That is, while the blocking device 500 blocks the communication port, both the stirring device 300 and the tub 100 remain stationary with respect to the tub 200.

When the laundry treating apparatus of the present embodiment is started, the blocking device 500 is in an initial state, i.e., separated from the communication port on the stirring device 300, and the communication port is kept open. When the laundry treating apparatus judges that the washing course to be operated is the washing course in which the second washing space B independently holds water, it is operated according to the flow shown in fig. 5.

Before water inflow is started, the plugging device 500 is controlled to be switched from an initial state to a state of plugging the communication port, and then the second water inflow device is started to inflow water into the second washing space B. After the water inlet process is finished, the washing process is started.

In the washing process, the blocking device 500 maintains the state of blocking the communication port, and thus the stirring device 300 is kept stationary due to the sealing contact with the valve plug of the blocking device 500, and the load in the second washing space B is washed by controlling the rotation of the pulsator 400.

Specifically, the laundry treating apparatus controls the pulsator 400 to alternately rotate in the forward and reverse directions during the washing process. The laundry treating apparatus presets a plurality of different washing courses, and the different washing courses correspond to different rotation stop ratios of the pulsator 400, so that different washing forces can be generated. The laundry treating apparatus controls the pulsator 400 to alternately rotate forward and reverse according to a corresponding rotation/stop ratio according to a currently operated washing program, thereby washing the load in the second washing space B with a proper washing force.

After the washing is finished, the plugging device 500 is controlled to open the communication port, so that the water in the second washing space B is discharged through the communication port. Specifically, after the washing is finished, the valve plug of the plugging device 500 is controlled to retract downward to be separated from the communication port, and the communication port can be opened to drain water. The water in the second washing space B is discharged into the washing tub 100 through the communication port, and is then discharged into the tub 200 through the washing tub 100, and finally is discharged out of the laundry treating apparatus along the drain pipe 800.

Further, after the laundry treating apparatus finishes the draining, the above operations of the water inlet process, the washing process, and the draining process may be repeated one to more times, thereby rinsing the load in the second washing space B several times. In the rinsing process, the blocking device 500 is controlled to block the communication port, and water is independently contained in the second washing space B. After the end of the draining process of the last rinsing, the blocking device 500 maintains a state in which the communication port is opened, and the laundry treating apparatus is ready to dehydrate the load.

In the dehydrating process of the present embodiment, the laundry treating apparatus controls the stirring device 300 to rotate to dehydrate the load in the second washing space B.

Specifically, the laundry treating apparatus controls the stirring device 300 to rotate at a high speed, and the water portion removed from the load flows upward along the inner sidewall of the second washing space B and is thrown out through the opening 302. The other part of the water removed also flows downward along the inner sidewall of the second washing space B, and since the communication port is opened at this time, the part of the load dehydration flowing downward can be discharged from the communication port during the dehydration.

Further, similar to the above-described embodiments, the stirring device 300 and the pulsator 400 are also controlled to rotate synchronously during dehydration of the laundry treating apparatus of the present embodiment.

In this embodiment, the plugging device 500 is disposed below the stirring device 300, and when the communicating port is plugged, the stirring device 300 is fixed, and the laundry treatment apparatus applies stirring to the washing water by controlling the pulsator 400 to rotate in the second washing space B, so as to wash the load in the second washing space B. Because the plugging device 500 is opened at the communication port, the rotation of the stirring device 300 is not affected, and the communication port can be kept open during the dehydration process, so that the load can be discharged from the bottom of the stirring device 300 in time for dehydration. On the one hand, the load is prevented from absorbing water again to improve the dehydration rate of the load, and on the other hand, the step of draining water again after the dehydration is finished can be omitted, so that the problem that residual water exists in the second washing space B can be avoided.

Example IV

As shown in fig. 4, this embodiment is different from the second or third embodiment in that: the height of the stirring device 300 is lower than the height of the tub 100.

Specifically, the height of the stirring device 300 in this example is less than half of the height of the washing tub 100, and the pulsator 400 is disposed at the bottom of the second washing space B.

Compared with the second and third embodiments, since there is no space below the pulsator 400 for only holding washing water but not holding the washed load, the amount of water held in the second washing space B is smaller, so that the amount of water required for washing is smaller and water is saved more when the second washing space B holds the small washing load independently.

In a preferred version of this embodiment, the laundry treating apparatus further comprises a cover openable and closable at the opening 302. The cover body can be buckled at the opening 302, when the second washing space B independently holds water for washing, the washing water can be prevented from splashing out of the opening 302, the condition of insufficient washing water quantity is caused, and meanwhile, the problem that a load is thrown out of the opening 302 in the dehydration process is avoided.

And when the clothes treatment equipment washes in the first washing space A and the second washing space B simultaneously, and the washing water level in the first washing space A is higher than the height of the opening 302, the buckling cover body at the opening 302 can also prevent the load in the second washing space B from drifting out of the opening 302 and entering the first washing space A.

In this embodiment, when the second washing space B is used for independently holding water, the stirring device 300 can rotate relative to the washing tub 100, and the cover needs to seal the opening 302. In this way, when the laundry treating apparatus simultaneously washes in the first washing space a and the second washing space B, and the washing water level in the first washing space a is higher than the height of the opening 302, the opening 302 may be sealed by the cover, so as to ensure that the washing water in the two washing spaces are isolated from each other, thereby ensuring the cross contamination preventing effect when the laundry treating apparatus simultaneously washes different types of loads.

When the second washing space B is independently filled with water, the stirring device 300 may be stationary with respect to the washing tub 100, that is, when the laundry treating apparatus simultaneously washes in the first washing space a and the second washing space B, the washing water in the two washing spaces may flow, and the cover may be a cover capable of sealing the opening 302, or may only have a function of blocking the load, but the washing water may still flow between the two washing spaces through the cover. For example, a plurality of water permeable holes can be arranged on the cover body to realize the communication between the upper space and the lower space of the cover body.

As a specific solution of this embodiment, the cover is detachably mounted on the stirring device 300, and a user may autonomously select whether to fasten the cover at the opening 302 according to the specific situation of the load to be washed. For example, in the case where the second washing space B is independently filled with water for washing, when the amount of the washed load is small, and the actual water level in the second washing space B is low, since the washing water is splashed out of the opening 302 and the risk that the load is thrown out of the opening 302 during dehydration is small, the cover may not be installed, and the opening 302 is always opened during washing.

Because the laundry treatment apparatus needs to feed water into the second washing space B through the opening 302, when the cover body is not required to be fastened to the opening 302, the laundry treatment apparatus can directly run the subsequent washing process after finishing the water feeding operation, without the need of a user to perform the operation, which is advantageous for improving the washing efficiency.

And when the cover body is required to be installed in the current washing, the clothes treatment equipment pauses operation after finishing the water inlet operation to the second washing space B, and sends out prompt information to a user to remind the user to lock the cover body. After the user engages the cover with the opening 302, the continuous operation command may be triggered, and the laundry treatment apparatus may continue to operate the washing process to wash the load in the second washing space B.

As another specific embodiment of this embodiment, the cover is installed at the opening 302 of the stirring device 300, and can open or close the opening 302. Each time the laundry treating apparatus is operated, after the water inflow operation to the second washing space B is completed, a user is required to manually snap-fit the cover body, thereby closing the opening 302.

In the above scheme, even though the washing water splashes out of the opening 302 or the risk that the load is thrown out of the opening 302 is small, the cover body needs to be buckled, so that the opening 302 is shielded, and the problem that the load in the second washing space B is thrown out in the dehydration process can be prevented to the greatest extent.

In this embodiment, the agitation device 300 provided in the laundry treating apparatus is shorter, thereby saving more water when the second washing space B independently holds water to wash the small load. Meanwhile, the cover body which can be buckled at the opening 302 is arranged on the clothes treatment equipment, so that the problem that washing water splashes out of the opening 302 or is thrown out of the opening 302 when a small load is dehydrated is effectively prevented.

Example five

This embodiment is further defined in the second or third embodiment, as shown in fig. 5, the opening area of the opening 302 is larger than the cross-sectional area of the middle area of the second washing space B in the height direction. By increasing the open area of the opening 302, it is more convenient for a user to take and put laundry through the opening 302.

Meanwhile, the second washing space B in this embodiment increases in cross-sectional area only in the area near the opening 302, while the cross-sectional area of the middle area remains at a small level. Because a certain interval is kept between the highest water level in the second washing space B and the opening 302, the cross-sectional area is increased in the area close to the opening 302, and obvious change of the maximum water holding amount in the second washing space B is not caused, so that the water saving effect of the second washing space B when the water is independently held for cleaning the small load is not influenced.

Preferably, in the present embodiment, the inner sidewall of the second washing space B extends downward in the vertical direction below the pulsator 400, so that the excessive water storage amount of the second washing space B below the pulsator 400 is avoided.

In a further aspect of this embodiment, the distance between the inner sidewall of the second washing space B and the rotation axis of the stirring device 300 is gradually increased from the middle region of the second washing space B toward the top opening 302, so that a structure is formed in which the opening area of the opening 302 is larger than the cross-sectional area of the middle region of the second washing space B.

Specifically, the second washing space B in this embodiment has a circular cross section, and the inner diameter of the second washing space B gradually increases from the middle region toward the top. While the inner diameter of the second washing space B remains substantially unchanged under the pulsator 400.

In this embodiment, the laundry treating apparatus dehydrates the load in the second washing space B where the washing is completed by controlling the stirring device 300 to rotate at a high speed. For the scheme of the second embodiment, since the communication port at the bottom of the stirring device 300 is blocked by the blocking device 500 during the dehydration process, the water draining from the bottom of the stirring device 300 to the outside cannot be achieved during the dehydration process. And to the scheme of embodiment three, though the intercommunication mouth keeps opening in the dehydration in-process, can outwards drain, nevertheless receives centrifugal force effect, and load dehydration laminating is in the inside wall flow of second washing space B, and the intercommunication mouth sets up with the bottom periphery interval of second washing space B, and then the outside efficiency of discharging of water of taking off through the intercommunication mouth is limited.

The inner side wall of the second washing space B is gradually inclined outwards from the middle area to the top opening 302, and the water removed from the load tends to flow to the area with larger inner diameter of the second washing space B under the action of centrifugal force, so that most of the water removed from the load flows upwards along the inner side wall of the second washing space B and is thrown out from the opening 302, thereby being beneficial to improving the dehydration rate.

In this embodiment, by increasing the inner diameter of the second washing space B near the area of the opening 302, on the one hand, the increase of the water containing volume of the second washing space B can be avoided under the condition of increasing the opening area of the opening 302, thereby ensuring the water saving effect when the second washing space B independently contains water for washing while facilitating the user to take and put clothes. On the other hand, the load dehydration can be promoted to flow upwards along the inner side wall of the second washing space B during the dehydration process, and then the load is thrown out from the opening 302, so that the dehydration rate of the load is improved.

The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
