Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically relates to a washing equipment and a control method thereof. Background Art

[0002] In the present invention, the "washing equipment" refers to a general term for a class of household appliances that can execute programs such as washing, dewatering, and drying, such as washing machines, washer-dryers, etc.

[0003] The barrel of the existing washing equipment is usually an accommodating cavity that penetrates up and down, and the air outlet of its drying device is installed at the barrel opening of the barrel. When the drying program is executed, the drying device sends hot air into the accommodating cavity of the barrel from the top of the barrel through the air outlet. However, after the laundry is washed or dehydrated, it is in a natural stacked state, and the hot air can only dry the outer surface of the laundry. Often, after the drying program is completed, most of the laundry is still wet.

[0004] The invention patent with the application number 201710577348.0 discloses a clothes hanger for a pulsator dryer, including: a main support member that can be fixed in the drying cavity of the pulsator dryer; a clothes hanging assembly, the clothes hanging assembly includes a plurality of clothes hanging members, the plurality of clothes hanging members are arranged along the circumference of the main support member, and one end close to the main support member is connected to the main support member; auxiliary support members, there are a plurality of the auxiliary support members, and the plurality of auxiliary support members respectively support between the plurality of clothes hanging members and the main support member. This patent solves the problem of low drying efficiency due to the stacking of wet clothes in the barrel when the washing machine executes the drying program.

[0005] However, the clothes hanger in this patent contains a large number of clothes hanging members and support members, and the structure is complex. Moreover, every time the clothes are dried, it is necessary to manually fix the clothes hanger in the barrel, and the installation and disassembly process greatly wastes the user's energy and time, reducing the usability of the washing equipment.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a washing equipment, by setting a cross-bar type hanging member in the barrel and a traction structure that drives the hanging member to reciprocate up and down between the pulsator and the barrel opening, so as to simplify the clothes hanging device and automatically stretch the stacked clothes in the barrel, and improve the drying efficiency of the clothes in the barrel and the usability of the washing equipment.

[0008] Another purpose of the present invention is also to provide a control method applied to the above-mentioned washing equipment, so as to realize the purpose of adjusting the hanging member to move up and down between the pulsator and the barrel opening of the barrel as different processing programs are switched, and ensuring the coordinated and smooth operation of each device in the equipment.

[0009] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0010] A washing device includes a vertically arranged barrel body and a pulsator rotatably installed at the bottom of the barrel body.

[0011] It further includes: a suspension member horizontally disposed in the barrel body and capable of lifting and lowering;

[0012] A traction structure connected to the suspension member and driving the suspension member to lift and lower;

[0013] When the suspension member descends onto the pulsator, the traction structure can be disconnected from the traction structure.

[0014] Further, an inner guide groove extending from the bottom of the barrel body to the barrel opening along the axial direction of the barrel body is provided on the inner wall of the barrel body;

[0015] The traction structure includes a guiding portion connected to the suspension member, and the guiding portion passes through the inner guide groove and slides between the bottom of the barrel and the barrel opening.

[0016] Further, an outer guide groove extending from the bottom of the barrel body to the barrel opening along the axial direction of the barrel body is provided on the outer surface of the side wall of the barrel body, and a through hole penetrating the barrel wall and connecting the inner guide groove and the outer guide groove is provided at the barrel opening;

[0017] The guiding portion can penetrate into the outer guide groove from the bottom of the barrel body and slide upward to the barrel opening, and then penetrate into the inner guide groove from the through hole and slide downward to the bottom of the barrel.

[0018] Further, the traction structure includes a driving portion coaxially arranged below the pulsator;

[0019] The guiding portion is provided as a bendable flexible strip, and the driving portion is connected to the guiding portion and can independently rotate to wind the guiding portion, so as to lengthen or shorten the length of the guiding portion penetrating into the inner and outer guide grooves.

[0020] Further, two inner guide grooves and two outer guide grooves symmetrically distributed with respect to the central axis of the barrel body are provided on the side wall of the barrel body, and two guiding portions symmetrically distributed with respect to the central axis of the barrel body are correspondingly provided on the traction structure.

[0021] Further, a sunken groove is provided on the upper surface of the pulsator, and the sunken groove extends radially through the pulsator and forms a notch on the upper surface of the pulsator, and the suspension member is embedded into the sunken groove from the notch.

[0022] Further, the suspension member is in a strip shape and connection portions are respectively provided at both ends of the suspension member, and the connection portions can be combined with or separated from the guiding portion.

[0023] Further, the agitator is provided with ribs protruding from its upper surface and distributed along its radial direction, and the suspension member can be bent and folded at least in a vertical plane to fit the surface of the agitator.

[0024] Preferably, the suspension member is a chain.

[0025] More preferably, the suspension member is a rope.

[0026] Further, the connecting portion is a magnet, and the end of the guiding portion is provided with an electromagnet.

[0027] The present invention also provides a control method applied to the above-mentioned washing equipment. Before executing the drying instruction, the suspension member is controlled to rise from the bottom of the barrel that can rotate synchronously with the agitator to hover at the barrel opening at the top of the barrel body.

[0028] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

[0029] 1. A traction structure is arranged along the barrel wall, so that the suspension member is horizontally arranged in the accommodating cavity of the barrel body, and by arranging the suspension member to be able to adhere to the top surface of the agitator and rotate synchronously with the agitator, the interference of the suspension member on the movement of the clothes in the barrel is avoided, ensuring the smooth execution of the washing and dehydration programs that require the rotation of the agitator and / or the barrel body. After dehydration, the suspension member is lifted by the traction structure to stretch out the stacked clothes, and the drying process can be quickly entered, avoiding manual setting by the user and improving the user experience.

[0030] 2. By arranging an inner guide groove on the side wall of the barrel body, the guiding portion can provide a supporting force for the suspension member relying on the rigidity of the inner guide groove, which not only simplifies the structure of the guiding portion, but also reduces the requirement for the rigidity of the guiding portion and expands the materials that can be used for the guiding portion. Driving the suspension member by the guiding portion moving up and down in the inner guide groove can save the accommodating cavity of the barrel body and improve the clothing processing efficiency.

[0031] 3. By arranging an outer guide groove on the outer side of the barrel wall of the barrel body and connecting it with a through hole, the guiding portion can enter the accommodating cavity from the outside of the barrel body. Using the inner and outer guide grooves to support the guiding portion can drive the suspension member more conveniently and effectively, and the traction structure can drive the guiding portion on the outside of the barrel body, making the distribution of each component of the traction structure relative to the barrel body more reasonable.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "communicated" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the present invention, the "washing device" refers to the general term for a class of household appliances that can perform programs such as washing, dewatering, and drying, such as washing machines, washer-dryers, etc.

[0043] Generally, the washing device includes a tub 10, a pulsator 20, and a drying device. The tub 10 has a receiving cavity and an opening is provided at its upper end. The pulsator 20 is installed at the bottom of the tub 10 and can rotate independently relative to the tub 10. The drying device extends axially along the outside of the tub 10. The air outlet of the drying device is installed at the opening of the tub 10, and hot air can be sent into the receiving cavity of the tub 10 from the top of the tub 10 through the air outlet.

[0044] Embodiment 1

[0045] Such as Figure 1 And Figure 2 As shown, in the embodiment of the present invention, a washing device capable of stretching the stacked clothes in the tub 10 is introduced.

[0046] The washing device includes: a vertically arranged tub 10, and a pulsator 20 rotatably installed at the bottom of the tub 10. In order to stretch the clothes in the tub 10, a hanging member 30 is also horizontally installed in the receiving cavity of the tub 10. The hanging member 30 can move up and down in the tub 10 in a horizontal posture along the axis of the tub 10.

[0047] During the execution of the washing instruction, the hanging member 30 is set to adhere to the upper surface of the pulsator 20. And the hanging member 30 can rotate synchronously with the pulsator 20. Similarly, during the execution of the dewatering instruction, the hanging member 30 is also set to adhere to the upper surface of the pulsator 20. It is set that the hanging member 30 abuts against the top of the pulsator 20 as the bottom of the tub 10 in the tub 10.

[0048] Relatively, it is set that the hanging member 30 hovers at the top of the tub 10 as the opening of the tub 10 in the tub 10. The top is specifically close to the opening of the tub 10 and below the opening.

[0049] In addition, in order to be able to control the movement of the hanging member 30 according to the needs of the work instruction, the washing device is also provided with a traction structure 40. The traction structure 40 is arranged on the barrel wall of the tub 10 and is controllably connected to the hanging member 30 to drive the hanging member 30 to move up and down in the tub 10, or is controllably separated from the hanging member 30 to ensure that the hanging member 30 rotates synchronously with the pulsator 20.

[0050] In this embodiment, a traction structure 40 is arranged along the barrel wall, so that the suspension member 30 is horizontally arranged in the accommodation cavity of the barrel body 10, and by arranging the suspension member 30, it can adhere to the top surface of the agitator 20 and rotate synchronously with the agitator 20, avoiding interference of the suspension member 30 with the movement of the clothes in the barrel, ensuring the smooth execution of the washing and dehydration programs that require the rotation of the agitator 20 and / or the barrel body 10. After dehydration, the suspension member 30 is lifted by the traction structure 40 to stretch out the stacked clothes, enabling rapid entry into the drying process, avoiding manual setting of a clothes hanger, and improving the user experience.

[0051] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, a structure for ensuring the stable movement of the suspension member 30 in the barrel body 10 is introduced.

[0052] An inner guide groove 13 is arranged on the inner surface of the side wall of the barrel body 10. And the inner guide groove 13 extends from the bottom of the barrel to the barrel opening along the axial direction of the barrel body 10. In addition, the traction structure 40 includes a guiding portion 41, which can be connected to the end of the suspension member 30 to drive the movement of the suspension member 30.

[0053] Specifically, the guiding portion 41 can be passed through the inner guide groove 13, and the guiding portion 41 is slid between the bottom of the barrel and the barrel opening. Thus, the suspension member 30 is driven to move up and down between the agitator position and the barrel opening position.

[0054] At this time, the end of the suspension member 30 can be embedded in the inner guide groove 13 or located outside the inner guide groove 13.

[0055] In this embodiment, by arranging the inner guide groove 13 on the side wall of the barrel body 10, the guiding portion 41 can rely on the rigidity of the inner guide groove 13 to provide a supporting force for the suspension member 30, which not only simplifies the structure of the guiding portion 41, but also reduces the requirement for the rigidity of the guiding portion 41 and expands the materials that can be used for the guiding portion 41. By driving the suspension member 30 through the guiding portion 41 that moves up and down in the inner guide groove 13, the accommodation cavity of the barrel body 10 can be saved and the clothing processing efficiency can be improved.

[0056] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, an optimized structure of the barrel body 10 is introduced to ensure the stable movement of the suspension member 30 in the barrel body 10.

[0057] An outer guide groove 14 is arranged on the outer surface of the side wall of the barrel body 10. The outer guide groove 14 is flush with the inner guide groove 13 on the side wall of the barrel body 10 and extends from the bottom of the barrel to the barrel opening along the axial direction of the barrel body 10.

[0058] In addition, to facilitate the insertion of the traction structure 40 from the outside of the barrel body 10 into the accommodation cavity, the barrel body 10 is provided with a through hole 15 penetrating the barrel wall at the barrel opening. The through hole 15 communicates the inner guide groove 13 with the outer guide groove 14, so that the guiding portion 41 can penetrate into the outer guide groove 14 from the bottom of the barrel body 10 and slide upward to the barrel opening, and then penetrate into the inner guide groove 13 through the through hole 15 and slide downward to the bottom of the barrel.

[0059] In this embodiment, by providing the outer guide groove 14 on the outer side of the barrel wall of the barrel body 10 and using the through hole 15 for communication, the guiding portion 41 can enter the accommodation cavity from the outside of the barrel body 10. The inner and outer guide grooves 14 are used to support the guiding portion 41 more conveniently and effectively drive the suspension member 30 to operate, and the traction structure 40 can drive the guiding portion 41 on the outside of the barrel body 10, so that the various components of the traction structure 40 are more reasonably distributed relative to the barrel body 10.

[0060] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, a traction structure 40 that can reduce the volume of the washing device and facilitate transmission is introduced.

[0061] The traction structure 40 includes a driving portion 42 for applying a force to the guiding portion 41. The driving portion 42 is coaxially arranged below the pulsator 20. Preferably, the driving portion 42 can be arranged between the bottom of the barrel body 10 and the pulsator 20, or can be arranged below the bottom of the barrel body 10. The traction structure 40 is connected to the guiding portion 41, and applies a force for sliding along the inner and outer guide grooves 14 to the guiding portion 41 by rotation.

[0062] Specifically, the guiding portion 41 is provided as a bendable flexible strip. The driving portion 42 can rotate independently relative to the pulsator 20 and the barrel body 10. The driving portion 42 is connected to the guiding portion 41, and can wind or release the guiding portion 41 during rotation to extend or shorten the length of the guiding portion 41 penetrating into the inner and outer guide grooves 14.

[0063] In this embodiment, the guiding portion 41 is provided as a bendable flexible structure, so that the traction structure 40 can coil and control the position of the end of the guiding portion 41 in the inner and outer guide grooves 14 by the rotation of the driving portion 42. The suspension member 30 is connected to the end of the guiding portion 41, and the effect of the suspension member 30 moving up and down along the inner guide groove 13 can be achieved.

[0064] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, a traction structure 40 that can more stably drive the suspension member 30 is introduced.

[0065] In order to apply balanced driving forces to both ends of the suspension member 30, the traction structure 40 is provided with two guiding portions 41. The two guiding portions 41 are respectively connected to both ends of the suspension member 30.

[0066] Correspondingly, two inner guiding grooves 13 and two outer guiding grooves 14 are provided on the side wall of the barrel body 10. The inner and outer guiding grooves 14 are symmetrically distributed relative to the central axis of the barrel body 10. Moreover, the two guiding portions 41 are inserted into the inner and outer guiding grooves 14 on both sides, forming a structure that is symmetrically distributed relative to the central axis of the barrel body 10.

[0067] In this embodiment, the traction structure 40 is arranged in a form that is symmetric about the central axis of the barrel body 10, which can drive the suspension member 30 to move in the barrel body 10 in a balanced manner, making the operation process of the suspension member 30 smoother, reducing the risk of damage to components, and improving the service life of the washing device.

[0068] As Figure 1 and Figure 2 shown, in the embodiments of the present invention, a structure of the agitator 20 for better hiding the suspension member 30 is introduced.

[0069] In order to reduce the collision between the suspension member 30 and the laundry when the suspension member 30 is on the agitator 20, a sunken groove 21 is provided on the upper surface of the agitator 20 for receiving and fixing the suspension member 30.

[0070] Specifically, the sunken groove 21 extends along the diameter direction of the agitator 20 on the upper surface of the agitator 20 and penetrates the agitator 20. In addition, the sunken groove 21 is recessed downward from the upper surface of the agitator 20 to form a notch on the upper surface of the agitator 20. Thus, when the suspension member 30 moves downward in the barrel body 10, it can be conveniently inserted into the sunken groove 21 from the notch.

[0071] In this embodiment, by providing the sunken groove 21 on the upper surface of the agitator 20, the suspension member 30 can be hidden in the agitator 20, and when the agitator 20 rotates, the contact between the suspension member 30 and the laundry can be reduced or avoided, ensuring that the washing device can smoothly perform washing or dehydration work.

[0072] As Figure 1 and Figure 2 shown, in the embodiments of the present invention, a suspension member 30 that is automatically connected or disconnected from the traction structure 40 is introduced.

[0073] Specifically, the suspension member 30 is in a long strip shape. For example, the suspension member 30 can be set as a chain structure, the suspension member 30 can be set as a cable structure, and the suspension member 30 can also be set as a rope structure.

[0074] Specifically, in order to automatically connect to or disconnect from the guiding portion 41, connection portions 31 are respectively provided at the ends of the hanging member 30. The connection portions 31 can be set as magnets, and electromagnets are correspondingly provided at the ends of the guiding portion 41. The connection portions 31 can be controllably combined with or separated from the guiding portion 41.

[0075] In another embodiment, the connection portion 31 is provided as an annular structure with a central through hole, and a hook is correspondingly provided at the end of the guiding portion 41. When the hanging member 30 moves to the position of the agitator, the guiding portion 41 continues to move downward for a certain distance, so that the hook can be disengaged from the connection portion 31. When the hanging member 30 moves towards the position of the bucket opening, the guiding portion 41 moves upward for a certain distance to connect the hook with the connection portion 31, and then drives the hanging member 30 to move upward to the position of the bucket opening.

[0076] In this embodiment, the hanging member 30 and the traction structure 40 are respectively provided with structures that can be automatically connected or disconnected, so that when the washing device runs different working instructions, each device can be connected and cooperate to run, thereby making the process of handling clothes smoother and improving the convenience of the washing device.

[0077] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, an agitator 20 capable of better embedding the hanging member 30 is introduced.

[0078] The agitator 20 is provided with rib protrusions 22 protruding from its upper surface. The rib protrusions 22 are distributed along the diameter of the agitator 20. The sink 21 is provided at the center line position of the rib protrusions 22. When viewed from the side, the line of the sink 21 along the contour of the rib protrusions 22 completely coincides with the rib protrusions 22.

[0079] Specifically, the hanging member 30 can be bent and folded at least in a vertical plane to fit the surface of the agitator 20. For example, the hanging member 30 is bent and embedded in the sink 21 along the line of the contour of the rib protrusions 22 to form a shape that fits the agitator 20.

[0080] Preferably, the hanging member 30 can be set as a chain.

[0081] More preferably, the hanging member 30 can be set as a rope.

[0082] In this embodiment, the sink 21 is opened on the rib protrusions 22 of the agitator 20, and the sink 21 is arranged to extend along the contour formed by the rib protrusions 22 on the agitator 20, so that the hanging member 30 can be more smoothly embedded into the agitator 20.

[0083] The present invention further provides a control method applied to the above-mentioned washing device. Before executing the drying instruction, control the suspension member 30 to rise from the bottom of the barrel that can rotate synchronously with the agitator 20 to hover at the barrel opening at the top of the barrel body 10.

[0084] In this embodiment, the control method moves the suspension member 30 up and down between the agitator 20 and the barrel opening of the barrel body 10 by adjusting with the switching of different treatment programs, ensuring the coordinated and smooth operation of each device in the washing device, and improving the treatment effect on clothes and the convenience of using the washing device.

[0085] Embodiment Two

[0086] As Figure 3 shown, in the embodiment of the present invention, a control method for a washing device is introduced.

[0087] The washing device includes: a suspension member 30 horizontally mounted in the barrel body 10 along the radial direction, and a traction structure 40 for driving the suspension member 30 to move. In addition, the suspension member 30 can reciprocate axially between the agitator position and the barrel opening position.

[0088] The control method includes the following steps: Obtain the work instruction to be executed, and control the washing device to first detect whether the suspension member 30 is at the preset position of the work instruction.

[0089] If the suspension member 30 is not at the preset position of the work instruction, then control to execute the program for moving the suspension member 30. That is, control the suspension member 30 to move to the preset position of the work instruction and then execute the work instruction.

[0090] On the contrary, if the suspension member 30 is already at the preset position of the work instruction, then control to directly execute the work instruction.

[0091] In this embodiment, it is set that the suspension member 30 has a corresponding preset position during the execution of each work instruction, so as to avoid the suspension member 30 interfering with the movement of the clothes when washing or dehydrating the clothes. By detecting the real-time position of the suspension member 30 and controlling the suspension member 30 to move to the preset position, it is ensured that different work instructions can be connected and run orderly, and each device in the washing device can run smoothly, improving the actual use effect of the suspension member 30.

[0092] As Figure 3 shown, in the embodiment of the present invention, a method for controlling the movement of the suspension member 30 in the barrel body 10 is introduced.

[0093] The moving program includes: a first program for moving the suspension member 30 to the barrel opening position, and a second program for moving the suspension member 30 to the agitator position.

[0094] In addition, both the first and second procedures have steps for detecting whether the suspension member 30 is connected to the traction structure 40.

[0095] In this embodiment, the moving direction of the suspension member 30 in the barrel 10 is subdivided, and a first procedure and a second procedure for controlling the movement of the suspension member 30 are set according to different target positions, so that the control method can more precisely control the movement process of the suspension member 30 in the barrel 10.

[0096] As Figure 3 shown, in the embodiment of the present invention, the specific steps for controlling the movement of the suspension member 30 are introduced.

[0097] In order to avoid failures of devices such as the traction structure 40 when driving the suspension member 30 to move, when executing the first procedure, it is necessary to first detect whether the suspension member 30 is connected to the traction structure 40.

[0098] After confirming that the suspension member 30 is in a connected state with the traction structure 40, then control the traction structure 40 to move the suspension member 30 to the position of the barrel opening.

[0099] In this embodiment, by setting a detection step to confirm the real-time state of the suspension member 30, failures such as the disconnection between the movement process of the suspension member 30 and the next work instruction are avoided, ensuring that the traction structure 40 can reliably lift the suspension member 30 to the position of the barrel opening.

[0100] As Figure 3 shown, in the embodiment of the present invention, a method for controlling the components of the washing device to operate in the order of work instructions is introduced.

[0101] The work instructions include a drying instruction. The preset condition for executing the drying instruction is that the suspension member 30 needs to be located at the position of the barrel opening all the time during the execution of the drying instruction.

[0102] After obtaining that the washing device is about to execute the drying instruction, first detect whether the suspension member 30 has already been located at the position of the barrel opening.

[0103] If the suspension member 30 has already moved to the position of the barrel opening, then directly execute the drying instruction and control the drying device to operate.

[0104] If the suspension member 30 has not yet moved to the position of the barrel opening, then execute the first procedure. That is, first detect whether the suspension member 30 is in a connected state with the traction structure 40. After confirming that the suspension member 30 is in a connected state with the traction structure 40, then control the traction structure 40 to move the suspension member 30 to the position of the barrel opening.

[0105] In this embodiment, by controlling the hanging member 30 to move to the position of the barrel opening before drying the clothes, the clothes stacked in the barrel body 10 can be stretched by the hanging member 30, so that the hot air blown by the drying device can contact the clothes more fully, improving the drying efficiency of the washing equipment.

[0106] As Figure 3 shown, in the embodiment of the present invention, the specific steps of controlling the hanging member 30 to move towards the position of the agitator are introduced.

[0107] Execute the second program. First, control the traction structure 40 to move the hanging member 30 to the position of the agitator, and then control the traction structure 40 to disengage from the hanging member 30.

[0108] To avoid the failure that the driving hanging member 30 and the traction structure 40 are not disengaged, it is also necessary to detect whether the traction structure 40 and the hanging member 30 are still connected. If the traction structure 40 and the hanging member 30 have been disengaged, the work instruction can be started to be executed.

[0109] If the traction structure 40 and the hanging member 30 are still connected together, it is necessary to repeat the second program of moving the hanging member 30 towards the agitator 20 once again, so that the traction structure 40 and the hanging member 30 are disengaged.

[0110] In this embodiment, by controlling the hanging member 30 to move to the position of the agitator before washing or dehydrating, the hanging member 30 can rotate together with the agitator 20, avoiding the contact or even collision between the clothes and the hanging member 30 during the operation of the washing and dehydration instructions. Thus, when the agitator 20 rotates, the contact between the hanging member 30 and the clothes can be reduced or avoided, ensuring that the washing equipment can smoothly execute the washing or dehydration work.

[0111] As Figure 3 shown, in the embodiment of the present invention, a method of controlling the movement of the hanging member 30 during dehydration of the clothes is introduced

[0112] The work instruction includes a dehydration instruction. The preset condition for executing the dehydration instruction is that the hanging member 30 needs to be always located at the position of the agitator during the operation of the dehydration instruction.

[0113] After obtaining that the washing equipment is about to execute the dehydration instruction, first detect whether the hanging member 30 has already been located at the position of the agitator.

[0114] If the hanging member 30 has moved to the position of the agitator, directly execute the dehydration instruction to control the barrel body 10 to rotate and operate.

[0115] If the suspension member 30 has not been moved to the position of the barrel opening, the second program is executed. That is, first control the traction structure 40 to move the suspension member 30 to the position of the agitator, and then control the traction structure 40 to disengage from the suspension member 30. After that, check whether the traction structure 40 and the suspension member 30 are still connected. If the traction structure 40 and the suspension member 30 have been disconnected, the dehydration instruction is started to be executed.

[0116] In this embodiment, by controlling the suspension member 30 to move to the position of the agitator and then dehydrating the clothes, it is ensured that the suspension member 30 can be hidden in the agitator 20, and the contact between the suspension member 30 and the clothes can be reduced or avoided during the dehydration process of the clothes, ensuring that the washing equipment smoothly executes the dehydration work.

[0117] As Figure 3 shown, in the embodiment of the present invention, a control method for connecting the suspension member 30 and the traction structure 40 is introduced.

[0118] Execute the first program, first check whether the suspension member 30 and the traction structure 40 are connected. If the suspension member 30 and the traction structure 40 are in a connected state, control the traction structure 40 to move the suspension member 30 to the position of the barrel opening.

[0119] If the suspension member 30 and the traction structure 40 are not connected, control the agitator 20 to rotate to dock the suspension member 30 and the traction structure 40.

[0120] In this embodiment, by controlling the rotation of the agitator 20, the agitator 20 can be rotated to the initial position where the suspension member 30 can be connected to the traction structure 40, thereby realizing the automatic connection of the suspension member 30 and the traction structure 40, improving the convenience of the washing equipment and the smoothness of the operation process.

[0121] As Figure 3 shown, in the embodiment of the present invention, a control method for eliminating wrinkles of clothes is introduced.

[0122] Specifically, after obtaining the drying instruction, check whether the suspension member 30 is located at the position of the barrel opening. If not, execute the first program and then execute the drying instruction. If it is detected that the suspension member 30 is already located at the position of the barrel opening, control to execute the drying instruction.

[0123] In addition, during the execution of the drying instruction, control the traction structure 40 to drive the suspension member 30 to reciprocate up and down at a high frequency along the axial direction of the barrel body 10.

[0124] In another embodiment of the present invention, in order to prevent the hanging member 30 from falling from the position of the barrel opening after the washing device is turned off, after the drying instruction is executed, the second program is controlled to be executed. That is to say, first control the traction structure 40 to move the hanging member 30 to the position of the agitator, and then control the traction structure 40 to disengage from the hanging member 30. After that, check whether the traction structure 40 and the hanging member 30 are disengaged. Finally, turn off the washing device.

[0125] In this embodiment, by controlling the hanging member 30 to move up and down at a high frequency in the barrel body 10, the effect of shaking and jittering the clothes is achieved, so as to utilize the inertial force generated by gravity to stretch the wrinkles of the clothes, thereby improving the clothes treatment effect.

[0126] As Figure 1 and Figure 2 shown, the present invention also provides a washing device adopting the above control method.

[0127] The washing device includes: a vertically arranged barrel body 10, and an agitator 20 rotatably installed at the bottom of the barrel body 10.

[0128] In order to hang up the clothes stacked in the barrel body 10, the washing device is further provided with a hanging member 30 and a traction structure 40. The hanging member 30 is horizontally arranged in the barrel body 10 along the radial direction. The traction structure 40 is connected to the hanging member 30 and can drive the hanging member 30 to reciprocate axially between the position of the agitator and the position of the barrel opening.

[0129] In this embodiment, by providing the hanging member 30, it is possible to avoid manually setting up a clothes hanger and automatically stretch the clothes stacked in the barrel, thereby improving the drying efficiency of the clothes in the barrel and the convenience of using the washing device.
