Specifically, as shown in fig. 1, the drum washing machine includes a cabinet (not shown), an outer tub (not shown) and a rotatable drum 1 disposed in the outer tub, wherein a plurality of first mounting holes 12 extending in a radial direction thereof are uniformly distributed on a drum wall 11 of the drum 1 along a circumferential direction thereof. As shown in fig. 1, three distribution areas of the first mounting holes 12 are uniformly distributed on the cylinder wall 11 of the cylinder 1 along the circumferential direction, 12 first mounting holes 12 are uniformly distributed in each distribution area, and the 12 first mounting holes 12 are distributed in a 4×3 array. It should be noted that, in a specific application, the size, shape, number, and other features of the first mounting holes 12 in this embodiment may be adjusted, and the above arrangement is only an exemplary arrangement, and does not limit the scope of protection of the present invention, and in a practical application, the first mounting holes 12 may be flexibly adjusted, for example, the distribution area of 2, 4, or more first mounting holes 12 may be disposed on the cylinder wall 11 of the cylinder 1, and the first mounting holes 12 in each distribution area may be arranged in a 3×3 array, a 3×5 array, a 4×4 array, or other array.

As shown in fig. 2 to 5, the first mounting hole 12 includes a first cylindrical section 121 and a second cylindrical section 122 which are distributed from the inside toward the outside of the drum 1 in the axial direction thereof, the diameter of the first cylindrical section 121 is smaller than that of the second cylindrical section 122, a first stepped surface 123 is formed at the junction of the first cylindrical section 121 and the second cylindrical section 122, a telescopic member is accommodated in the first mounting hole 12, the telescopic member includes a first cylindrical section 21, a second cylindrical section 22 and bristles 23 fixed on one end of the first cylindrical section 21 toward the inside of the drum 1, the bristles 23 are made of silica gel, the bristles 23, the first cylindrical section 21 and the second cylindrical section 22 are arranged to be distributed from the inside toward the outside of the drum 1 in the axial direction of the first mounting hole 12, the diameter of the first cylindrical section 21 is smaller than that of the second cylindrical section 22, a second stepped surface 24 is formed at the junction of the first cylindrical section 21 and the second cylindrical section 22, the second cylindrical section 22 is slidably connected with the second cylindrical section 122, and when the bristles 23 are all protruded from the first mounting hole 12, the second stepped surface 24 abuts against the first stepped surface 123, thereby restricting the movement of the first cylindrical section 21, the second cylindrical section 22 and the bristles 23 toward the inside of the drum 1.

As shown in fig. 2 and 4, the first mounting hole 12 further accommodates therein a driving device including a magnet 31 and an electromagnet 32, the magnet 31 being disposed at an end of the second cylindrical section 22 near the outside of the drum 1, the electromagnet 32 being fixed to the first mounting hole 12. The first columnar section 21 and the second columnar section 22 have a rectangular parallelepiped structure. As shown in fig. 3 and 5, two gaps 221 for drainage are formed between both side portions of the second cylindrical section 22 and positions corresponding to the inner walls of the first mounting holes 12. As shown in fig. 2 and 4, the other opposite sides of the second cylindrical section 22 are slidably connected to positions corresponding to the inner walls of the first mounting holes 12, and the opposite sides are provided with a second mounting hole 25, respectively. The first mounting hole 12 is internally provided with a limiting part, the limiting part comprises a plurality of concave structures 41 with triangular cross sections, clamping members 42 and springs 43, the concave structures 41 are distributed on the side walls of the first mounting hole 12 opposite to the second mounting hole 25 along the axial direction of the first mounting hole 12, the clamping members 42 are slidably connected with the inner walls of the second mounting hole 25, the tail parts (one ends close to the second mounting hole 25) of the clamping members 42 are connected with the second mounting hole 25 through the springs 43, and the head parts (one ends close to the outer side of the second mounting hole 25) of the clamping members 42 are arranged to be identical to the concave structures 41. In a state in which the telescopic member is fully retracted into the first mounting hole 12, the head of the click member 42 abuts against the inner wall of the first mounting hole 12, and the click member 42 compresses the spring 43 under the pressing of the inner wall of the first mounting hole 12 and is accommodated in the second mounting hole 25.

When the drum washing machine is in a washing stage, the electromagnet 32 is electrified to generate repulsive force with the magnet 31, the first cylindrical section 21, the second cylindrical section 22 and the bristles 23 are driven to move towards the inside of the drum 1 in the first mounting hole 12, the bristles 23 extend out of the first mounting hole 12 and enter the drum 1, and when the bristles 23 extend out of a certain length (such as half of the length), the electromagnet 32 is powered off. At this time, the clamping member 42 extends out of the second mounting hole 25, and the head of the clamping member 42 extends into the concave structure 41 at the corresponding position, and the head of the clamping member 42 abuts against the concave structure 41 to limit the telescopic member, so that the telescopic member keeps the current extending length to participate in washing of clothes in the drum 1.

When the drum washing machine is in a dehydration and acceleration stage, the electromagnet 32 is electrified with reverse current to generate suction force with the magnet 31, the first cylindrical section 21, the second cylindrical section 22 and the bristles 23 are driven to move towards the inside of the first mounting hole 12, the bristles 23 are fully retracted into the first mounting hole 12, at the moment, the head of the clamping member 42 is forced to move out of the concave structure 41, the clamping member 42 is retracted into the second mounting hole 25, then the electromagnet 32 is powered off, and at the moment, water in the drum 1 can be discharged between the drum 1 and the outer drum through two gaps 221 between the second cylindrical section 22 and the first mounting hole 12.

When the drum washing machine is in a dewatering and decelerating stage, the electromagnet 32 is electrified with forward current to generate repulsive force with the magnet 31, so that the first cylindrical section 21, the second cylindrical section 22 and the bristles 23 are driven to move in the first mounting hole 12 towards the interior of the drum 1, and all the bristles 23 extend out of the first mounting hole 12 and enter the drum 1. The electromagnet 32 is de-energized after the bristles 23 are fully extended. At this time, the engaging member 42 protrudes out of the second mounting hole 25, and the head thereof protrudes into the recess structure 41 at the corresponding position. Meanwhile, the second step surface 24 abuts against the first step surface 123, and limiting of the telescopic member can be achieved, so that the telescopic member can be stably kept in the current all-extending state, and the situation that the telescopic member extends too far when the driving device is abnormal is avoided.

The above arrangement has the advantages that: the drum washing machine can drain water through the dehydration holes of the drum 1, and can drain water through the two gaps 221 between the second cylindrical section 22 and the first mounting hole 12 during dehydration, so that the drainage speed of the drum 1 is improved, and the use experience of a user is optimized. The repulsive force and the attractive force of the magnet 31 and the electromagnet 32 are utilized to control the first columnar section 21, the second columnar section 22 and the bristles 23 to extend/retract in the first mounting hole 12, the telescopic member is limited through the matching of the concave structure 41 and the clamping member 42, and meanwhile, the telescopic member can be limited through the matching of the first step surface 121 and the second step surface 24, so that the situation that the telescopic member extends too long when the driving device is abnormal is avoided, and the telescopic member is more stable and reliable in the extending process and fully extends. In the dehydration stage of the drum washing machine, the telescopic member extends from the first mounting hole 12 towards the drum 1, so that clothes attached to the drum wall 11 can be peeled off, and after dehydration is finished, a user does not need to manually pull the clothes from the drum wall 11 of the drum 1, so that the phenomenon that wrinkles are generated in the process of pulling the clothes from the drum wall 11 is avoided. In the washing stage, the telescopic member can also extend from the first mounting hole 12 towards the drum 1 for a certain length to participate in washing of clothes, so that the washing efficiency and the washing quality are improved.

It should be noted that the bristles 23 are made of silica gel, and the bristles 23 may be made of rubber or other elastic materials. Still alternatively, the telescopic member may further include only the first cylindrical section 21 and the second cylindrical section 22, and the whole telescopic member may be made of a material that does not damage clothes, such as a silica gel material or a rubber material, and by such arrangement, the manufacturing cost of the telescopic member may be reduced, and the assembly is simple. Alternatively, the electromagnet 32 may be fixed to the outer wall of the drum 1, or the electromagnet 32 and the magnet 31 may be positioned in the opposite direction, or the driving device may be configured as a first electromagnet and a second electromagnet, the first electromagnet being disposed at one end of the second cylindrical section 22 near the outer side of the drum 1, and the second electromagnet being disposed at the outer wall of the drum 1 or the first mounting hole 12. In addition, the concave structure 41 may be configured as a hemispherical structure, and accordingly, the head of the limiting structure 42 is also configured as a hemispherical structure. The above-mentioned arrangement of the shapes of the recess structure 41 and the limiting structure 42 is only one possible embodiment, and is not limited as long as the limiting structure 42 can be clamped in the recess structure 41.

In another possible embodiment, the limiting portion in the first mounting hole 12 may be further configured such that a plurality of elastic blocks are distributed on the inner wall of the first mounting hole 12 along the axial direction of the first mounting hole 12, the cross-sectional shape of the elastic blocks is triangular, when the driving device drives the first cylindrical section 21, the second cylindrical section 22 and the bristles 23 to extend/retract in the first mounting hole 12, the side portions of the second cylindrical section 22 squeeze the elastic blocks to deform the elastic blocks when the second cylindrical section 22 moves, and friction force generated between the side portions of the second cylindrical section 22 and the elastic blocks is generated, so that limiting of the telescopic members is realized by virtue of friction force between the side portions of the second cylindrical section 22 and the elastic blocks after the telescopic members stop moving.

In another possible embodiment, the second cylindrical section 22 may be provided such that only one side portion forms a gap 221 with the first mounting hole 12 for discharging the washing water of the dehydration stage of the drum 1. In another possible embodiment, the first cylindrical section and the second cylindrical section may also have a cylindrical structure, and accordingly, the first cylindrical section and the second cylindrical section have a cylindrical structure, the diameter of the second cylindrical section is smaller than that of the second cylindrical section, and the second cylindrical section is slidably connected to the inner wall of the second cylindrical section through a sliding rail assembly. The specific position of the gap formed by the two above-mentioned arrangement modes can be flexibly adjusted according to practical applications, as long as the water in the drum 1 can be accelerated to drain, but the gap cannot be formed at the connection side between the limiting portion and the second mounting hole 25.

In another possible embodiment, the first mounting hole 12 is a hole with a constant diameter, the telescopic member is a rod-shaped member with a constant diameter, the rod-shaped member is slidably connected with the inner wall of the hole, the driving device drives the rod-shaped member to move along the diameter of the hole in a telescopic manner, and the driving device stretches out for a set length in the dewatering and decelerating stage, so that the clothes attached to the wall 11 of the drum 1 are peeled off.

In another possible embodiment, the driving means may also drive the telescopic member with a linear motor. Specifically, the output shaft of the linear motor is connected to one end of the second cylindrical section 22 near the outside of the drum 1, and drives the telescopic member to extend/retract in the first mounting hole 12 in the axial direction thereof. It should be noted that the second cylindrical section 22 may be directly extended/retracted in the first mounting hole 12 without being slidably connected to the inner wall of the first mounting hole 12. In the dehydration stage of the drum washing machine, the linear motor can be controlled to drive the telescopic member to completely extend out from the first mounting hole 12 towards the drum 1 so as to peel off the clothes attached to the drum wall 11.

The control method of the present invention will be described in detail with reference to fig. 6. In one embodiment of the present invention, the drum washing machine is preset with three working stages, namely a washing stage, a dewatering and accelerating stage and a dewatering and decelerating stage, and the correspondence between the extending length of the brush hair 23 and the working stages, such as a washing stage, a dewatering and accelerating stage and a dewatering and decelerating stage, respectively correspond to one third of the length, no extending length and the whole length, are arranged in the memory of the drum washing machine. The control method of the drum washing machine specifically comprises the following steps:

s100: acquiring the current working stage of the drum washing machine;

for example, a user inputs an instruction for selecting a working phase on the control panel, and the controller obtains the current working phase of the drum washing machine according to the input instruction of the user.

S110: the current working stage is a washing stage, and the bristles are determined to extend one third of the length from the first mounting hole;

the controller determines the third length of the bristles 23 extending from the first mounting hole 12 based on the correspondence of the extension length of the bristles 23 stored in the memory and the working phase of the current washing phase.

S111: extending the bristles one third of the length from the first mounting hole;

for example, the controller controls the electromagnet 32 to be energized for 5 seconds and then de-energized, so that the bristles 23 extend one-third of the length from the first mounting hole 12.

S120: the current working stage is a dehydration speed-increasing stage, and the bristles are determined to be fully retracted into the first mounting holes;

the controller determines that the bristles 23 are fully retracted into the first mounting hole 12 from the correspondence between the extension length of the bristles 23 stored in the memory and the working phase according to the current dehydration acceleration phase.

S121: retracting the bristles entirely within the first mounting hole;

for example, the controller controls the electromagnet 32 to be de-energized, thereby causing the bristles 23 to be fully retracted into the first mounting hole 12.

S130: the current working stage is a dehydration and deceleration stage, and the bristles are determined to extend out of the first mounting hole for the whole length;

the controller determines the total length of the bristles 23 extending from the first mounting hole according to the correspondence between the extending length of the bristles 23 stored in the memory and the working phase in the current dehydrating and decelerating phase.

S131: extending all the bristles from the first mounting hole;

for example, the controller controls the electromagnet 32 to be energized for 15 seconds and then de-energized, so that the bristles 23 extend the entire length from within the first mounting hole 12.

By this arrangement, the washing stage can be selected when washing laundry, and the bristles 23 protrude one third of the length from the inside of the first mounting hole 12, thereby washing laundry effectively. In the dehydration acceleration stage of the laundry, the bristles 23 are fully retracted from the first mounting hole 12 so that the drum 1 can rapidly drain water. After the dehydration acceleration stage is completed, the dehydration deceleration stage is started, and the bristles 23 are fully extended from the first mounting holes 12 to peel off the clothes attached to the drum wall 11.

The washing mode may be automatically determined by the drum washing machine. In addition, the length of the bristles 23 extending from the first mounting hole 12 in the above embodiment is only an exemplary arrangement, and does not limit the scope of the present invention, and the length of the bristles 23 extending from the first mounting hole 12 may be flexibly adjusted in practical applications, for example, the bristles 23 may be arranged to extend from the first mounting hole 12 by a quarter length during the washing stage of the drum washing machine; the bristles 23 may be set to protrude from the inside of the first mounting hole 12 by two-thirds of the length in the dehydrating and decelerating stage of the drum washing machine.

In another possible embodiment, the bristles 23 may be extended from the first mounting hole 12 only during the spin-down stage, and the bristles 23 may be retracted into the first mounting hole 12 during both the washing stage and the spin-up stage.

Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
