In one embodiment, the washing tub assembly includes a washing tub, a magnet and a sensing module, a positioning groove is concavely formed in a bottom wall of the washing tub, the sensing module is disposed in the positioning groove, and the sensing module and the magnet can move relatively. In one embodiment, the washing tub assembly includes the related structures of the following embodiments, including but not limited to the washing tub, the magnet, the induction module, and the like.

To further illustrate the above-mentioned washing tub assembly, referring to fig. 1 and 2, the washing machine includes a tub pulsator 120 and a keg 130, the keg 130 is detachably mounted on the tub pulsator 120, and the tub pulsator 120 is used to drive the keg 130 to rotate. For example, the keg 130 is detachably mounted on the vat pulsator 120. Thus, the keg is convenient to disassemble. For example, the ways of removably attaching the keg to the keg impeller may include, but are not limited to, snapping, screwing, binding, tying, nesting, and the like. For example, referring to fig. 1 and fig. 2, a positioning column 121 is disposed on the barrel pulsator 120, a positioning groove 131 is concavely disposed on the outer side of the bottom wall of the keg 130, and the positioning column is matched with the positioning groove, so that the barrel pulsator drives the keg to rotate. The positioning column 121 is embedded or inserted in the positioning groove 131, and the positioning column 121 of the big barrel pulsator 120 is used for driving the small barrel 130 to rotate when the big barrel pulsator 120 rotates. For example, the shape of the positioning slot matches the shape of the positioning post. For another example, the shape or the cross-sectional shape of the positioning column is set to be triangular, quadrilateral and other polygonal or non-circular shapes, so that the keg is driven to rotate by the matching of the positioning column and the positioning groove through the vat wave wheel. Of course, in other embodiments, the cross-section of the positioning column may be circular. It can be understood that the locating column with the circular cross section is easier to align relative to the locating column with the non-circular cross section, so that the locating column and the locating groove can be more trouble-saving and convenient to install, and further the keg can be conveniently installed and disassembled.

It should be noted that, the conventional tub-in-tub washing machine, that is, the washing machine additionally provided with a small inner tub in the inner tub of the conventional pulsator washing machine, is poor in structural firmness when the small tub is mounted on the large tub pulsator in a manner of the positioning pillar and the groove, and when the small tub is used for washing, the situation that the small tub may fall off if the washing machine vibrates too much. In order to ensure that the keg has good structural firmness after being mounted on the barrel wave wheel and is not easy to fall off, in an embodiment, please refer to fig. 1 and fig. 2 again, a plurality of slots 1211 are formed on the outer side wall of the positioning column 121, even if a subsequent position-limiting insertion column is inserted into a slot, a plurality of position-limiting insertion columns 1311 are arranged on the inner side wall of the positioning slot 131 of the keg 130, and the position-limiting insertion columns 1311 are at least partially embedded or inserted into the slots 1211. So, because the reference column inlays in the constant head tank, and through the cooperation of spacing post and slot of inserting for the keg is installed to vat wave wheel and is gone up the back structural firmness better, and the keg is difficult for droing. For another example, the positioning column 121 is disposed in the middle of the big tub impeller 120. Of course, in other embodiments, a plurality of positioning columns or positioning grooves may be provided and respectively provided at a plurality of positions on the large-barrel pulsator. In this embodiment, as shown in fig. 2, the number of the positioning posts and the positioning grooves is one. Through setting up reference column 121 in the middle part of vat impeller 120, can make the installation convenience of keg better. As another example, as shown in fig. 2, the locating post 121 has a circular cross-section along the height of the keg, or its outer sidewall has a circular cross-section. The positioning groove 131 has a circular cross section in the keg height direction. So, through designing into circular cross-section with the reference column to combine spacing cooperation of inserting post and slot, make the keg install to vat impeller last back structural firmness better, thereby make the keg be difficult for droing. For example, the limit inserting column is matched with the inserting groove and limits the position, so that the big barrel wave wheel drives the small barrel to rotate when rotating. So, be convenient for the vat impeller through spacing the cooperation of inserting post and slot in order to drive the keg and rotate. For another example, the shape of the slot matches the shape of its corresponding limit post. For another example, the position-limiting studs 1311 are embedded in the slots 1211 in a one-to-one correspondence. So, through the cooperation of spacing post 1311 of inserting with slot 1211, can further improve the structural firmness behind keg installation to the vat impeller for be difficult for droing in the keg use. In one embodiment, the position-limiting insertion column 1311 has a rectangular structure, and the slot 1211 has a rectangular cross section, for example, the position-limiting insertion column 1311 has a strip-shaped protrusion structure, the slot 1211 has a boundary surface matched with the position-limiting insertion column 1311, and the position-limiting insertion column 1311 and the slot 1211 form a clearance fit. So, spacing post 1311 of inserting has better limiting displacement after inserting in the slot for the fine bucket is installed to the big bucket wave wheel after structural soundness better. For another example, the slots 1211 are disposed at intervals along the rotation axis of the drum 120. For another example, the slots 1211 are disposed in a circular array along the rotation axis of the drum 120. So, can make keg 130 more firm with the installation intensity of vat impeller for the vat is difficult for droing at the dehydration process. In another example, a large drum impeller penetrating hole 1212 is further formed in the large drum impeller 120, and the large drum impeller penetrating hole penetrates through the top end of the positioning column 121.

Referring to fig. 1 and 2, the large tub impeller 120 is provided with a plurality of ribs 122, and the plurality of ribs 122 of the large tub impeller 120 are distributed in a circular array around the rotation center of the large tub impeller 120, so that the ribs on the large tub impeller can perform a better water flow disturbance function. For another example, the big barrel wave wheel is provided with convex ribs along the radial direction. If the drum impeller 120 is rotated in the forward direction, the convex rib 122 of the drum impeller 120 has the first water-stirring surface 1221 and the second water-stirring surface 1222 opposite to each other, the first water-stirring surface has opposite ends along the radial direction of the drum impeller, the first water-stirring surface gradually protrudes from the two ends to the middle part of the first water-stirring surface in the direction away from the second water-stirring surface, the second water-stirring surface has opposite ends along the radial direction of the drum impeller, the second water-stirring surface gradually protrudes from the two ends to the middle part of the second water-stirring surface in the direction away from the first water-stirring surface, and thus the first water-stirring surface and the second water-stirring surface protruding outward slightly can improve the water flow disturbance effect of the drum impeller, so that the drum impeller rotates in the forward direction and rotates in the reverse direction to. For another example, the first water-pouring surface and the second water-pouring surface of the convex rib are arranged in bilateral symmetry.

When the convex rib 122 is disposed on the barrel pulsator, in order to fully utilize the limiting function of the convex rib 122 to further improve the structural firmness of the keg mounted on the barrel pulsator, in one embodiment, please refer to fig. 1 to 2, the keg 130 is provided with a plurality of limiting grooves 133 on the outer side of the bottom wall thereof, and the convex rib 122 of the barrel pulsator 120 is embedded in the limiting grooves 133. If so, when the keg 130 is embedded into the positioning column 121 through the positioning groove 131, the limiting grooves 133 on the keg are also embedded into the convex ribs, so that the structural firmness of the keg after being installed on the vat wave wheel is further improved, and the keg is not easy to fall off in the using process. For another example, the ribs 122 of the barrel pulsator 120 are distributed in a circular array around the rotation axis of the barrel pulsator 120. For another example, the number of the ribs of the big barrel impeller is 5 to 12. Preferably, the number of the ribs 122 of the tub pulsator 120 is 5. So, on the one hand, it has better rivers disturbance effect, and on the other hand, it has further improved the structural firmness behind keg installation to vat wave wheel for keg is difficult for droing in the use. For another example, referring to fig. 2, the large-barrel pulsator 120 is a circular flat structure as a whole. So, the vat impeller of flat structure is more suitable for the installation keg for keg can comparatively firmly install on the vat impeller.

In order to further improve the structural firmness of the keg after the keg is mounted on the keg impeller and avoid the problem that the keg falls off during the dehydration rotation process driven by the keg impeller, in an embodiment, referring to fig. 3, which is a schematic view, the limiting insert pillar 1311 is provided with a protruding portion 13111, the positioning pillar 121 is provided with a recessed groove 12111 on the sidewall of the insert groove 1211, when the limiting insert pillar 1311 is inserted or inserted into the insert groove 1211, the recessed groove 12111 corresponds to the protruding portion 13111, and the protruding portion 13111 can be at least partially accommodated in the recessed groove 12111, according to the actual use process, the recessed groove position and the protruding portion position can be set on the side toward which the centrifugal tangential force in the dehydration rotation process of the keg faces, or the side to which the circumferential force in the dehydration rotation process points. Or the position of the concave groove is arranged on the side, facing the centrifugal tangential force, of the limiting inserted column in the dehydration rotation process of the small barrel, and the position of the convex part is arranged on the side wall, facing the centrifugal tangential force, of the inserting slot in the dehydration rotation process of the small barrel. So, establish the groove through setting up the concave and protruding portion of establishing, at the rotatory in-process of dehydration, under the effect of dehydration centrifugal tangential force, protruding portion of establishing can at least part holding in the concave inslot of establishing, make the concave groove of establishing have certain limiting displacement to protruding portion of establishing, thereby make the slot to inserting the post have certain limiting displacement, and then make the reference column of vat impeller have better limiting displacement to the constant head tank of keg, can further improve the structural firmness behind the keg installation to the vat impeller, avoid the vat impeller to drive the rotatory in-process of keg dehydration, the problem that drops appears in the keg. In a particular embodiment the side walls of the keg have an angle of inclination, typically 1.5-30 degrees, such that the water of the keg is easily flung out through the inclined side walls under the centrifugal force of the dewatering rotation, but there is a risk that the keg is unstable and even flung out when the centrifugal force of the dewatering rotation is too large. In this embodiment, establish groove 12111 and protruding portion 13111 of establishing through setting up the concave, can improve the structural firmness behind keg installs to the vat impeller betterly, drive the rotatory in-process of keg dehydration at the vat impeller, improve the stability of keg. For another example, the protruding portion 13111 has a rectangular parallelepiped structure, and the recessed groove 12111 also has a rectangular cross section. Alternatively, the concave grooves 12111 match the shape of the convex portions 13111. Of course, the protruding portion and the protruding portion may have other shapes as long as the slot has a certain limiting effect on the limiting insertion column. In order to reduce the noise generated when the vat wave wheel drives the vat to rotate, in one embodiment, a rubber strip is still arranged between the slot and the limiting insertion column, so, the noise generated when the vat wave wheel drives the vat to rotate can be reduced by additionally arranging the rubber strip. When the rubber strip is arranged, the rubber strip is properly kept away at the position of the concave groove or the convex part.

It should be noted that, in a conventional pulsator washing machine, which generally has a washing tub and a pulsator disposed in the washing tub, water flow disturbance is realized by mutual rotation of the pulsator and the washing tub to wash laundry in the washing tub. However, in the existing washing machine, if the washing tub is abnormal and cannot normally rotate or the pulsator is abnormal and cannot normally rotate in the operation process of the washing program, the equipment is easily damaged, and even a user use accident occurs.

In order to detect the working condition of the washing barrel in the running process of the washing program in real time, in one embodiment, the application further provides the washing machine, the washing machine comprises the washing barrel, a magnet and an induction module, a positioning groove is concavely arranged on the bottom wall of the washing barrel, the induction module is arranged in the positioning groove, and the induction module and the magnet can move relatively.

In one embodiment, the sensing module is fixed on the inner side wall of the positioning groove, the washing tub assembly further comprises a washing tub impeller, and the magnet is fixed on a driving assembly of the washing tub impeller. So, among the washing procedure operation process, relative rotation can take place for washtub impeller and washtub, and then make the response module with but magnet relative motion, through accepting in real time and analyzing the signal of telecommunication of response module, combine the washing control procedure simultaneously, and then just can analyze out the behavior of washtub and washtub impeller betterly. In one embodiment, the magnet is ring-shaped, and the magnet is fixedly sleeved on the driving component of the impeller of the washing barrel. Thus, a better magnetic field effect can be provided.

In a specific embodiment, the induction module includes an induction coil and an information transmitting module, the induction coil is electrically connected to the information transmitting module, and both the induction coil and the information transmitting module are disposed in the positioning groove. Therefore, the induction coil is positioned in the magnetic field of the magnet, when the induction coil and the magnet generate relative motion, the magnetic flux passing through the induction coil is changed, and then the induction coil generates current or an electric signal, for example, when the induction coil and the magnet rotate relatively, the induction coil generates current to drive the information transmitting module to generate a preset signal. For another example, when the induction coil and the magnet rotate relatively, the induction coil generates a current, and the information transmitting module is configured to generate a preset signal according to the current generated by the induction coil. For example, the preset signal is at least one of a wireless signal, a sound signal, an optical signal and a vibration signal, and the wireless signal is at least one of a bluetooth signal, a WIFI signal, an infrared signal and a radio frequency signal. The sound signal may be a continuous sound, such as playing a pre-recorded audio or a honey sound. The light signal may emit a flickering light. The vibration signal may generate a vibration. Preferably, the preset signal is a wireless signal. The wireless signal is at least one of a Bluetooth signal, a WIFI signal, an infrared signal and a radio frequency signal. Of course, the wireless signal is not limited thereto. In order to install induction coil and information emission module better, in one embodiment, be equipped with annular coil holding tank on the inside wall of constant head tank and with the spacing holding tank that the coil holding tank link up mutually, induction coil sets up in the coil holding tank, information emission module sets up in spacing holding tank. Thus, the induction coil and the information transmitting module can be well installed. In a further embodiment, the magnet is located within the induction coil, i.e. the induction coil has a circular ring structure, and the magnet is located in the middle, or in the center area, of the circular ring structure of the induction coil. For another example, the magnet also has a ring structure, the magnet is located in the induction coil, and the magnet is concentric with the induction coil.

In another embodiment, the sensing module is a magnetic inductor and an information sending module, when the magnetic inductor and the magnet move relatively, the magnetic inductor generates an electrical signal, and the information sending module is configured to send a preset signal according to the electrical signal. For another example, the washing machine further comprises a processor and a power supply, the magnetic inductor, the information sending module and the power supply are all electrically connected with the processor, and the processor is used for controlling the information sending module to send out a preset signal when the magnetic inductor generates an electric signal. In another example, the power source is a battery. For another example, the battery is a lithium ion battery, a button battery or a dry battery.

In one embodiment, the induction module is an induction coil and a magnet, the induction coil and the magnet are located at the same horizontal height, the induction coil and the magnet can rotate relatively, and when the induction coil and the magnet rotate relatively, the induction coil generates current to drive the information transmitting module to generate a preset signal.

In one embodiment, the washing barrel can be a washing barrel of a conventional common pulsator washing machine, and can also be a small barrel of a washing machine with a barrel-in-barrel function. In one embodiment, the washing tub is a keg of a washing machine having a "tub-in-tub" function. At the moment, the small barrels can be provided with the wave wheels or not provided with the wave wheels.

When not setting up the impeller in the keg, magnet can install on the diapire of vat, if again, magnet installs on the diapire of vat, so, when vat impeller drives the keg and carries out the washing procedure in the keg, if the keg does not install in place or drop, then the unable normal drive keg rotation of vat impeller, and then make the unable signal of telecommunication that produces of response module or produce weaker signal of telecommunication, can judge the behavior of keg through to its analysis. If, again, vat impeller epirelief is equipped with the reference column, and it is formed with the magnet mounting groove with vat impeller opposite side, and the magnet mounting groove stretches into to the reference column in, the protruding magnet erection column that is equipped with of diapire of vat, magnet are installed on the magnet erection column, and the magnet erection column stretches into to the magnet mounting groove in. As another example, the magnet and the sensing module are located at the same level. So response module and magnet are in same level for the magnetic field intensity that response module received is stronger, and then can better produce the signal of telecommunication. In practical applications, the level signal may be used as a threshold value, and when the washing tub is not installed in place, the sensing module and the magnet are not at the same height, the sensing module generates a weaker level signal. Thus, the condition of the washing tub can be judged by analyzing the intensity of the electric signal. If the induction module is the induction coil and the signal sending module, the induction coil and the magnet are at the same horizontal height, when the induction coil rotates relative to the magnet, current is generated to provide power for the information transmitting module, the information transmitting module can send out a preset signal, and the condition of the keg can be judged by analyzing the preset signal. When induction coil and magnet were not in same level, then can make the unable information transmission module work of driving of electric current that induction coil produced, so, can correctly install the target in place to the keg and detect.

In one embodiment, the keg is provided with a keg impeller, and the magnet can be arranged on a driving component of the keg impeller. That is, the washing tub as above is a keg, and the washing tub pulsator as above may be a keg pulsator.

The following description will be continued in conjunction with a washing machine having a tub-in-tub function. It should be noted that, in the conventional barrel-in-barrel washing machine, when the small barrel is mounted on the large barrel impeller to be washed, if the small barrel is not correctly mounted in place, the large barrel impeller cannot drive the small barrel to rotate, so that the purpose of washing the clothes in the small barrel cannot be achieved. And in the cleaning process, if the small barrels fall off from the big barrel wave wheel, the small barrels are easy to incline to make clothes fall into the big barrel or fall into the side wall of the small barrels, so that the washing effect is poor or the washing effect cannot be achieved, the noise is high during subsequent dehydration, and the equipment abrasion is increased. It is therefore necessary to detect in real time whether the keg falls off the keg impeller during the washing of the clothes in the keg. In one embodiment, referring to fig. 4 to 6, the washing machine includes a small tub 130 and a large tub pulsator 120. The locating slot 131 has been seted up to the diapire of keg, is provided with reference column 121 on the vat impeller, and the keg passes through the cooperation of locating slot and reference column and spacing installation vat impeller is last. Referring to fig. 4 to 6, the washing machine further includes an induction coil 410 and an information transmitting module 420,

the induction coil 410 is installed in the positioning groove 131, the information transmitting module 420 is electrically connected to the induction coil 410, the induction coil 410 is used for rotating relative to the magnet 450 therein to generate current to provide power for the information transmitting module 420, and the information transmitting module is used for transmitting signals when being electrified. It should be noted that the induction coil is used for cooperating with the magnet to enable the information sending module to transmit a signal that the keg is in a normal operating state, for example, to a washing machine host/controller/user. When the magnet rotates relative to the induction coil, the induction coil is located in the magnetic field of the magnet, and when the magnetic flux passing through the induction coil changes, the induction coil can generate current, so that the information sending module can transmit the signal that the keg is in a normal working state according to the current signal of the induction coil. Specifically, for example, the information sending module includes, but is not limited to, a wireless sending module. Preferably, the information sending module is a wireless sending module, so that the host machine of the washing machine, the controller of the washing machine or other terminals can judge whether the keg is in a correct working state or not by sending wireless signals and receiving the wireless signals sent by the host machine of the washing machine, the controller of the washing machine or other terminals through analyzing the wireless signals. For another example, the wireless transmission module is electrically connected to the induction coil, the induction coil is configured to rotate relative to a magnet therein to generate a current to provide power for the wireless transmission module, and the wireless transmission module is configured to transmit a wireless signal when powered on. In one embodiment, the wireless sending module is at least one of an infrared sending module, a bluetooth sending module and a WIFI sending module. Of course, the wireless transmission module is not limited thereto. As shown in fig. 4 at 430 is a keg insert and at 440 is a coil mount for mounting and receiving the induction coil 410 and the information transmitting module 420, the keg insert is used to enclose or mount the coil mount in a locating groove.

In one embodiment, the magnet is required to be set to rotate asynchronously with the drum impeller, i.e., when the drum impeller rotates, the magnet does not rotate, or when the drum impeller rotates, the magnet and the drum impeller rotate relatively. Thus, when the big barrel impeller drives the small barrel to rotate, the induction coil also rotates, so that the induction coil 410 rotates relative to the magnet 450 therein, and the induction coil generates current to provide power for the information sending module.

In this embodiment, by providing the induction coil 410 and the information transmitting module 420, the induction coil 410 is configured to rotate relative to the magnet 450 therein to generate a current to provide power for the information transmitting module 420, and the information transmitting module 420 is configured to transmit a signal when powered on, so that, after the keg 130 is mounted on the keg impeller 120, the magnet 450 is located in the induction coil 410, when the keg impeller 120 drives the keg 130 to normally rotate, the induction coil 410 rotates relative to the magnet 450, and when a magnetic flux passing through the induction coil 410 changes, the induction coil 410 can generate a current to further provide power for the information transmitting module 420, so that the information transmitting module 420 can send a signal. The keg can be judged to be installed in place by receiving signals sent by the information transmitting module in real time. On the contrary, the keg is not installed in place or the keg comes off from the big barrel wave wheel, then induction coil can't produce relative rotation for magnet, and induction coil can't produce electric current, and information emission module can't signal, when unable received signal, then can judge that the keg comes off or not installs in place. So, can be to whether the keg drops from the vat wave wheel in the clothes cleaning process in the keg and carry out real-time detection, be convenient for washing program's control and stop.

It should be noted that, however, the conventional drum-in-drum washing machine (i.e. a pulsator washing machine with a large drum sleeved with a small drum) still has the following disadvantages: on one hand, the existing barrel-in-barrel washing machine is mainly driven by a Direct Drive (DD) variable frequency motor, the DD variable frequency motor has a complex structure and high cost, the cost of the whole machine is increased, the selling price of the barrel-in-barrel washing machine is higher, and the barrel-in-barrel washing machine is difficult to serve the public due to price factors. On the other hand, the washing effect of clothing is relatively poor in the keg, and the washing of clothing in the keg mainly relies on the bellied muscle of keg inner wall to realize that the rivers disturbance is washd, so, relative motion between clothing and the rivers just is relatively more weak, just also relatively poor to the washing effect of clothing. In order to reduce the cost of the washing machine and improve the cleaning effect of the small barrels, in an embodiment, referring to fig. 6 and 7, the washing machine further includes an outer barrel, a large barrel, a driving device, and a small barrel impeller 140, the large barrel is accommodated in the outer barrel, the large barrel impeller 120 is accommodated in the large barrel, the small barrel 130 is detachably mounted on the large barrel impeller 120, the small barrel 130 is accommodated in the large barrel, and the impeller small barrel 140 is accommodated in the small barrel 130.

It should be noted that the outer tub in this embodiment plays a role in supporting and mounting as a whole. For example, the washing machine further includes a cabinet in which the outer tub is located. Please refer to the prior art for the specific arrangement of the outer barrel and the box body. The large barrel in the embodiment is equivalent to a washing barrel of a traditional pulsator washing machine and is used for washing clothes. When the washing machine only comprises an outer barrel, a large barrel and a large barrel impeller, the washing machine is similar to a traditional common impeller washing machine, clothes in the large barrel disturb water flow mainly through the large barrel impeller, and the clothes are washed by combining ribs convexly arranged on the inner side wall of the large barrel. The small barrel can be used for washing special clothes, such as underwear, socks, infant clothes and the like which need to be washed separately. Therefore, the cross contamination during the washing of the clothes is avoided.

In this embodiment, please refer to fig. 7, the driving device is a three-power clutch 150, and the three-power clutch 150 is disposed on the outer side of the bottom wall of the outer tub. Of course, the three-power clutch may not be fixed on the outer side of the bottom wall of the outer tub. The cost of the washing machine can be greatly reduced by combining the three-power clutch with the traditional common motor. Specifically, the triple clutch 150 has three coaxial power output shafts, namely a first power output shaft 151, a second power output shaft 152 and a third power output shaft 153. First power take-off shaft 151 is connected the diapire outside of vat, and first power take-off shaft 151 is used for driving vat 110 rotatory. The bottom wall of the vat is provided with a vat mounting hole, the second power output shaft penetrates through the vat mounting hole and is connected with the vat wave wheel 120, and the second power output shaft 152 is used for driving the vat wave wheel 120 to rotate. The barrel impeller 120 is also used for driving the keg 130 to rotate under the driving of the second power output shaft 152. The third power output shaft 153 sequentially passes through the vat mounting hole, the vat wave wheel through hole 1212 and the keg mounting hole 1312 and is connected with the keg wave wheel 140, and the third power output shaft 153 is used for driving the keg wave wheel to rotate. The three-power clutch described above requires a common motor to drive. As for how the three power clutches are driven by the motor and how the three power clutches control the first power output shaft, the second power output shaft and the third power output shaft to rotate independently, please refer to the prior art. For example, the triple clutch 150 has a transmission gear 154, and a common motor drives the transmission gear of the triple clutch through a belt to provide the capacity for the triple clutch. Of course, the general motor is a motor distinguished from the DD motor or referred to as a rotary motor having a rotary shaft. In this embodiment, through set up keg impeller in the keg, only rely on the bellied muscle of keg inner wall to realize the method that rivers disturbance washs in the tradition, through setting up keg impeller in the keg, can make the relative motion between clothing and the rivers stronger, can improve the rivers disturbance ability in the keg in the cleaning process to can improve the cleaning performance to clothing in the keg, it is better to the cleaning performance of clothing. The three-power clutch is used for replacing a traditional DD variable frequency motor, the three-power clutch can provide power drive through a common motor, the total cost of the three-power clutch and the common motor is lower than that of an expensive DD variable frequency motor, the cost is lower, the whole cost of the washing machine can be reduced, and therefore the washing machine with the bucket-in-bucket function can be more easily served to the public due to the lower cost.

Furthermore, it should be noted that in the conventional barrel-in-barrel washing machine, the power for washing the small barrel only drives the small barrel to rotate through the large barrel impeller, and the water flow disturbance is realized by the raised ribs on the inner wall of the small barrel for cleaning. The power of the big barrel impeller is mainly provided by a washing shaft of a DD (direct drive) motor. The DD motor power output shaft is divided into a washing shaft and a dewatering shaft, the dewatering shaft drives the big barrel to rotate, the washing shaft drives the impeller to rotate, the washing shaft is low in strength, and the force arm is long. When the small barrel is used for washing, the washing shaft is subjected to large torque and bending stress, and the bearing for fixing the washing shaft is abraded seriously indirectly. Because the washing shaft is limited in strength and the maximum torque which can be borne by the washing shaft is limited, the appearance is that the weight of clothes and water is limited during the washing of the small barrels, and therefore the rated washing capacity of the small barrels cannot be too large.

In this embodiment, through adopting three power clutch and keg impeller simultaneously, for traditional bucket-in-bucket washing machine, its keg only relies on the protruding muscle of establishing of the inside wall of the interior bucket of washing to realize that the rivers disturbance carries out abluent mode, and this application can realize stronger rivers disturbance effect through set up keg impeller in the keg to can improve the cleaning performance to the clothing. The traditional DD motor is replaced by the three power clutches, the three power clutches are provided with a plurality of third power output shafts compared with the DD motor, the third power output shafts drive the small barrel wave wheel to rotate, therefore, in the process of using the small barrel washing machine, the washing power of the small barrel is provided by the second power output shaft and the third power output shaft at the same time, the problem that the power for washing the small barrel of the traditional small barrel washing machine only drives the small barrel to rotate through the large barrel wave wheel is solved, the torque and the bending stress borne by the washing shaft driving the large barrel wave wheel are larger, the maximum torque borne by the washing shaft is limited due to the limited strength of the washing shaft, and the external appearance that the weight of clothes and water is limited during the small barrel washing is reflected, compared with the existing small barrel washing machine, the washing machine provided by the second power output shaft and the third power output shaft at the same time, the torque and the bending stress borne by the second power output shaft which drives the big barrel impeller are correspondingly reduced, so that the rated washing capacity of the small barrels can be improved, and the small barrels can wash clothes with larger capacity.

For example, one keg is used for cleaning infant clothes, another keg is used for cleaning socks, and yet another keg is used for cleaning underwear. Thus, the clothes can be better cleaned separately. However, if the wave wheel is introduced into the small barrels to improve the washing of the clothes in the small barrels, if one small barrel wave wheel is arranged in each small barrel, the overall cost of the washing machine is increased virtually. In order to facilitate a plurality of kegs to share one keg impeller and/or to facilitate replacement of the keg impeller, in one embodiment, referring to fig. 14 and 15, a plurality of spline tooth grooves 211 are formed at intervals on an outer side wall of the spline shaft 210.

As another example, the plurality of drain holes 130b1 are circumferentially spaced about the center of rotation of the keg. As another example, the plurality of drain holes 130b1 are distributed in a circumferential array about the center of rotation of the keg. Therefore, a plurality of water drainage holes are formed in the top of the keg side wall at intervals, and the positions of the water drainage holes correspond to the positions of the connecting parts 320, so that water can flow out along the water drainage holes 130b1 in the top of the keg side wall 130b in the dehydration process of the keg, and compared with the traditional method for draining water from the upper side of the water retaining ring, the arrangement of the keg and the water retaining ring in the embodiment can reduce the creeping height of the water and can directly drain the water from the water drainage holes in the top of the keg side wall 130b1, so that the dehydration efficiency can be improved, and the dehydration energy consumption can be reduced. For example, one end of the water-blocking portion 330, which is far away from the connecting portion 320, is provided with a water-blocking protrusion 331 protruding downward, and for another example, the water-blocking portion 330 is parallel to the bottom wall of the keg.
