Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and in particular, relates to a washing machine upper cover, a washing machine and a control method thereof. Background Art

[0002] At present, some washing machines are equipped with a spray water inlet program, which specifically includes: after the clothes are put in, the washing machine controls the spray component to spray water into the barrel of the washing machine to achieve the purpose of soaking the clothes; or, when the washing machine rinses the clothes, the spray component is controlled to spray water into the barrel of the washing machine to spray and rinse the clothes.

[0003] However, it is uncertain whether the spray assembly in the above technical solution can accurately spray water on the clothes, especially when there are fewer clothes. The clothes may stick to the inner wall of the barrel or only cover a partial area of ​​the bottom of the barrel. Blind spraying cannot ensure that the water can directly act on the clothes, and thus cannot achieve good soaking and rinsing of the clothes. In addition, the actual height of the clothes at different positions in the barrel is also different. Simply spraying water indiscriminately will cause uneven soaking and rinsing of the clothes at different positions in the barrel, and poor spraying effect.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The present invention provides a washing machine upper cover and a washing machine having the upper cover, so as to achieve the purpose of accurately detecting the height of clothes at different positions in the washing machine;

[0006] The present invention also provides a control method for a washing machine, so as to achieve the purpose of accurately positioning spraying and rinsing clothes, improving the efficiency of spraying and rinsing, and improving the uniformity of rinsing.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A washing machine upper cover comprises a distance measuring component movably arranged on the inner side of the upper cover and a driving component connected to the distance measuring component. The driving component drives the distance measuring component to move and is used to detect the height of clothes at different positions in the washing machine.

[0009] Furthermore, a track structure is laid on the inner side of the upper cover, and the distance measuring component is movably arranged on the track structure. The driving component drives the distance measuring component to move on the track structure and detect the height of the clothes corresponding to different positions of the track structure.

[0010] Furthermore, the track structure is spirally extended from the outer circumference of the upper cover toward the center thereof, and the distance measuring component can move along the spiral track structure and detect the height of the clothes corresponding to different positions of the spiral track structure.

[0011] Furthermore, the track structure includes a plurality of concentrically arranged tracks, the distance measuring components are respectively arranged on the plurality of tracks, and each distance measuring component moves to detect the height of the clothes corresponding to different positions of the plurality of tracks;

[0012] Alternatively, several circles of the track are transitionally connected by a connecting track, and the distance measuring component can move on the multiple circles of the track via the connecting track, and detect the height of the clothes corresponding to different positions of the connecting track and the multiple circles of the track.

[0013] Further, among the plurality of circles of the track, the connecting track is respectively arranged between any adjacent circles of the track; or, the connecting track is extended from the outermost circle of the track to the innermost circle of the track, and connects the plurality of circles of the track;

[0014] Preferably, the connecting track is extended from the outer peripheral edge of the upper cover to the innermost circle track and connects several circles of the track.

[0015] Furthermore, the distance measuring component has a roller in rolling contact with the track structure, and the driving component is connected to the roller, driving the roller to roll on the track structure, driving the distance measuring component to move and detect the height of clothes at different positions.

[0016] Furthermore, a reel for retracting and releasing the electric wire is provided on the inner side of the upper cover, and the free end of the electric wire is connected to the ranging component for powering the ranging component. When the ranging component moves to a position away from the reel, the reel rotates to release the wire, and the ranging component is energized to detect the height of clothes at different positions. When the reel reels in the wire, it drives the ranging component to move to a position close to the reel.

[0017] Furthermore, the ranging component includes a shell with a cavity inside, and a ranging head for sending a detection signal is arranged in the shell. The free end of the electric wire is passed through the shell and is electrically connected to the ranging head. When the shell moves to a position away from the reel, the reel rotates to pay out the wire and the ranging head is energized to detect the height of clothing at different positions.

[0018] The present invention also provides a washing machine, comprising a washing machine upper cover as described in any one of the above technical solutions;

[0019] Preferably, the washing machine includes a controller electrically or communicatively connected to the driving component and the ranging component, and a spray component connected to the controller. The controller controls the driving component to drive the ranging component to move and detect the height of clothes at different positions in the washing machine, and controls the spray component to spray water to the corresponding height position according to the detected height of clothes.

[0020] The present invention also provides a method for controlling a washing machine as described in the above technical solution, comprising:

[0021] The barrel depth h0 of the washing machine is preset, and the driving component is controlled to drive the distance measuring component to move and detect the height h of clothes at different positions in the washing machine, and the detected height h of clothes is compared with the preset depth h0. If h<h0, it is determined that there are clothes at this position, and the spray component is controlled to spray water toward this position in a directional manner;

[0022] Preferably, detecting the height of clothes at different positions in the washing machine includes: controlling the distance measuring component to move from the outer ring track of the upper cover to the inner ring track in sequence, controlling the reel of the distance measuring component to rotate and release the line during the movement, and powering on to detect the height h of clothes at different positions, and after the detection is completed, controlling the reel to reel in the line, and the distance measuring component moves from the inner ring track to the outer ring track in sequence;

[0023] Preferably, the spray water inlet duration and / or the spray water inlet intensity are controlled to be negatively correlated with the detected clothing height h.

[0024] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0025] In the present invention, under the driving action of the driving component, the distance measuring component can move on the inner side of the upper cover, and can detect the height of the clothes in the washing machine corresponding to different active positions in real time during the activity process. In this way, by reasonably controlling the activity trajectory of the distance measuring component, the height of the clothes at different positions can be fully and accurately detected, which helps the washing machine to perform accurate directional spraying according to the different detected heights, thereby improving the efficiency of spray washing or rinsing and avoiding ineffective spraying and wasting water and electricity resources.

[0026] The washing machine of the present invention has the washing machine upper cover of the present invention. By setting the washing machine upper cover of the present invention, the height of the clothes at different positions in the washing machine can be accurately detected, and then the spraying program of the washing machine can be reasonably controlled according to the actual height of the clothes.

[0027] In the present invention, a reel is provided to reel in and discharge the electric wire, so that electric energy can be continuously provided to the distance measuring component during the movement, and traction can be provided to the distance measuring component when the distance measuring component is retracted and reset, and the distance measuring component is assisted in reeling in the electric wire.

[0028] In the control method of the washing machine of the present invention, the driving component drives the distance measuring component to move, so that the distance measuring component detects the distance from the upper cover to different positions of the bottom end of the barrel body during the activity, and then makes a comprehensive judgment on whether there are clothes in the barrel body. When h<h0, it indicates that there are clothes at this position. At this time, water is controlled to be sprayed to this position, so that the spray water flow directly acts on the clothes, and the clothes are effectively sprayed and washed.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on 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", and "connected" 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The washing machine comprises a box body, an outer barrel arranged in the box body, and an inner barrel arranged in the outer barrel, wherein the inner barrel has an inner barrel opening for putting clothes, and the outer barrel has an outer barrel opening concentrically arranged outside the inner barrel opening. The upper cover 1 of the washing machine is openably arranged on the box body, and is used to open and close the outer barrel opening and the inner barrel opening.

[0043] like Figures 1 to 4 As shown, the present invention provides a washing machine upper cover 1, comprising a distance measuring component 4 movably arranged on the inner side of the upper cover 1 and a driving component connected to the distance measuring component 4, the driving component drives the distance measuring component 4 to move, and is used to detect the height of clothes at different positions in the washing machine. Among them, the distance measuring component 4 includes an acoustic sensor or a photoelectric sensor, etc. Taking the photoelectric sensor as an example, the washing machine controls the photoelectric sensor to emit light to the inner barrel, and judges the height of the clothes by the reflection time and / or reflectivity of the light.

[0044] Specifically, the driving component includes a motor disposed on the distance measuring component 4, the motor provides power for the distance measuring component 4, and drives the distance measuring component 4 to move inside the upper cover 1. The movement modes of the distance measuring component 4 include: the distance measuring component 4 rotates in different directions inside the upper cover, and detects the heights of clothes at different positions in different washing machines during the rotation process; or the distance measuring component 4 can move on the inner side surface of the upper cover, and detects the heights of clothes at different positions in different washing machines during the movement process.

[0045] In the present invention, under the driving action of the driving component, the distance measuring component 4 can move inside the upper cover 1, and can detect the height of the clothes in the washing machine corresponding to different active positions in real time during the activity. In this way, by reasonably controlling the activity trajectory of the distance measuring component 4, the height of the clothes at different positions can be fully and accurately detected, which helps the washing machine to perform accurate directional spraying according to the different detected heights, thereby improving the efficiency of spray washing or rinsing and avoiding ineffective spraying and wasting water and electricity resources.

[0046] As an embodiment of the present invention, a track structure 3 is laid on the inner side of the upper cover 1, and the distance measuring component 4 is movably arranged on the track structure 3. The driving component drives the distance measuring component 4 to move on the track structure 3 and detect the height of the clothes corresponding to different positions of the track structure 3. The movement mode of the distance measuring component 4 includes: the distance measuring component 4 is slidably arranged on the track structure 3; or the distance measuring component 4 is rollably arranged on the track structure 3.

[0047] More specifically, the inner side of the upper cover 1 has an outer barrel mouth matching portion 12 and an inner barrel mouth matching portion 13, the outer barrel mouth matching portion 12 and the inner barrel mouth matching portion 13 are concentrically arranged annular structures, and the track structure 3 is laid on the inner side of the upper cover 1 and is located in the area surrounded by the inner barrel mouth matching portion 13. Preferably, the track structure 3 is laid on the inner side of the upper cover 1 as evenly as possible.

[0048] Among them, the setting methods of the track structure 3 include: horizontal track structure, vertical track structure, circular track structure, etc.; for example: the track structure 3 includes a plurality of tracks laid horizontally on the inner side of the upper cover 1, and adjacent horizontal tracks are connected through the vertical track. The ranging component 4 can move on the horizontal track and move to another horizontal track adjacent to it through the vertical track.

[0049] In this embodiment, a track structure 3 is provided on the inner side of the upper cover 1, so that the distance measuring component 4 can move on the track structure 3, and the moving position is different, and the corresponding position in the inner barrel is also different. In this way, the distance measuring component 4 can comprehensively detect the height of the clothes at different positions in the inner barrel during the movement on the track structure 3.

[0050] As an implementation method of this embodiment, Figure 1 As shown, the track structure 3 is spirally extended from the outer periphery of the upper cover 1 toward the center thereof. The distance measuring component 4 can move along the spiral track structure 31 and detect the height of the clothes corresponding to different positions of the spiral track structure 31.

[0051] Specifically, the distance measuring component 4 first starts from one end of the spiral track structure 31 close to the outer periphery of the upper cover 1 and gradually moves toward the center along the spiral track structure 31. During the movement, the distance measuring component 4 detects the height of the clothes at different positions in the inner barrel from the outer periphery of the upper cover 1 to the center of the upper cover 1 in sequence, and the detection result is comprehensive and accurate; and the spiral track structure 31 is smooth and unobstructed, so that the distance measuring component 4 moves more smoothly, thereby improving the detection efficiency while ensuring the accuracy of the detection result.

[0052] When the distance measuring component 4 moves to the center position of the spiral track structure 31, the distance measuring component 4 can be controlled to gradually move and reset in the direction from the center position to the outer periphery of the upper cover 1. During the movement and reset process, the distance measuring component 4 can be controlled to detect the height of the clothes in the inner barrel again, so as to further supplement and improve the height information of the clothes at different positions in the washing machine.

[0053] As another implementation of this embodiment, the track structure 3 includes a plurality of concentrically arranged tracks, the distance measuring components 4 are respectively provided on the plurality of tracks, and each distance measuring component 4 moves to detect the height of the clothes corresponding to different positions of the plurality of tracks.

[0054] Specifically, the distance measuring components 4 on several circles of tracks can be controlled to move respectively. And the moving speed and moving time of each distance measuring component 4 can be adjusted according to the actual situation;

[0055] For example: control the moving speed of the ranging component 4 on the outer ring track to be greater than the moving speed of the ranging component 4 on the inner ring track, so that the ranging component 4 on the outer ring track and the ranging component 4 on the inner ring track start moving at the same time, and complete the detection of a whole cycle of the corresponding tracks in the same time.

[0056] For another example: when the moving speeds of the ranging components 4 are the same, the ranging components 4 on the outer ring track are controlled to start moving first, and after moving for a period of time, the ranging components 4 on the inner ring track are controlled to start moving. In this way, the moving time of each ranging component 4 is reasonably controlled to avoid repeated detection of the ranging components 4 on the inner ring track.

[0057] As another implementation method of this embodiment, Figure 3 and Figure 4 As shown, the track structure 3 includes a plurality of concentrically arranged tracks, and the plurality of tracks are transitionally connected by a connecting track. The distance measuring component 4 can move on the plurality of tracks via the connecting track, and detect the height of clothing corresponding to different positions of the connecting track and the plurality of tracks.

[0058] Specifically, Figure 3As shown, the plurality of orbits include an outermost orbit 32 and an innermost orbit 34, and the outermost orbit 32 and the innermost orbit 34 are transitionally connected via a third connecting orbit 37. The distance measuring component 4 can move from the outermost orbit 32 to the innermost orbit 34 via the third connecting orbit 37. During the movement of the distance measuring component 4, the height of the clothes in the inner tub corresponding to each position of the outermost orbit 32, the innermost orbit 34, and the third connecting orbit 37 can be detected in real time.

[0059] like Figure 4 As shown, the plurality of orbits include an outermost orbit 32 , a secondary outermost orbit 33 , and an innermost orbit 34 ; the outermost orbit 32 and the secondary outermost orbit 33 are transitionally connected via a first connecting orbit 35 ; the secondary outermost orbit 33 and the innermost orbit 34 are transitionally connected via a second connecting orbit 36 ​​.

[0060] The distance measuring component 4 can move from the outermost circle track 32 to the secondary outer circle track 33 through the first connecting track 35, and then move from the secondary outer circle track 33 to the innermost circle track 34 through the second connecting track 36. During the movement of the distance measuring component 4, the height of the clothes in the inner barrel corresponding to each position of the outermost circle track 32, the secondary outer circle track 33, the innermost circle track 34, the first connecting track 35, and the second connecting track 36 can be detected in real time.

[0061] As an embodiment of the present invention, among the plurality of circles of the tracks, the connecting tracks are respectively arranged between the tracks of any adjacent circles; for example, the first connecting track 35 and the second connecting track 36 are respectively separate tracks.

[0062] Alternatively, the connecting track extends from the outermost track 32 of the plurality of tracks to the innermost track 34, connecting the plurality of tracks. Preferably, the connecting track extends from the outer peripheral edge of the upper cover 1 to the innermost track 34, connecting the plurality of tracks.

[0063] In this embodiment, the setting mode of the connecting track is optional. When a connecting track only connects two adjacent circles of tracks, its position can be selected in a wide range, providing multiple options for the movement of the distance measuring component 4 on adjacent circles of tracks. When a connecting track connects all circles of tracks, it can not only realize the movement of the distance measuring component 4 on different tracks, but also greatly simplify the track laying layout.

[0064] As an embodiment of the present invention, Figure 2 As shown, the distance measuring component 4 has a roller 41 that is in rolling contact with the track structure 3, and the driving component is connected to the roller 41, driving the roller 41 to roll on the track structure 3, driving the distance measuring component 4 to move and detect the height of clothes at different positions. The driving component can be a motor, and the motor drives the roller 41 to roll, driving the distance measuring component 4 to move.

[0065] Preferably, a plurality of groups of rollers 41 may be provided on the distance measuring component 4 to ensure that the distance measuring component 4 can roll smoothly on the track structure 3 .

[0066] Further preferably, a slot structure is provided on the track structure 3 , and the roller 41 is rotatably mounted on the slot structure. When the upper cover 1 is closed, the roller 41 can roll on the track structure 3 without falling off the track structure 3 .

[0067] As another embodiment of the present invention, a reel 5 for retracting and releasing the electric wire 51 is provided inside the upper cover 1, and the reel 5 can automatically reel in and release the electric wire. The free end 511 of the electric wire is connected to the distance measuring component 4 for supplying power to the distance measuring component 4. When the distance measuring component 4 moves to a position away from the reel 5, the reel 5 rotates to release the wire, and the distance measuring component 4 is powered on to detect the height of the clothes at different positions. When the reel 5 retracts the wire, it drives the distance measuring component 4 to move to a position close to the reel 4.

[0068] Specifically, Figure 2 and Figure 3 As shown, the reel 5 is arranged on the outer peripheral edge of the inner side of the upper cover 1 . When there is no need to detect the height of the clothes in the washing machine, the reel 5 is in a reeled state, and the distance measuring component 4 is located on the outer peripheral edge of the inner side of the upper cover 1 .

[0069] When it is necessary to detect the height of the clothes in the washing machine, the reel 5 unwinds, and the distance measuring component 4 moves along the third connecting track 37 to the outermost circle track 32, moves one circle on the outermost circle track 32, and then moves along the third connecting track 37 to the innermost circle track 34, and moves one circle on the innermost circle track 34.

[0070] When it is necessary to reversely return the distance measuring component 4 to the outer peripheral edge of the inner side of the upper cover 1, the reel 5 is wound up, and when winding up the line, the distance measuring component 4 is pulled back along the "innermost circle track 34-third connecting track 37-outermost circle track 32-third connecting track 37".

[0071] In this embodiment, a reel is provided to reel in and out the electric wire, which can not only continuously provide power to the distance measuring component 4 during movement, but also provide traction force for the distance measuring component 4 when the distance measuring component 4 is retracted and reset, and assist in reeling in the electric wire.

[0072] As another embodiment of the present invention, Figure 2 As shown, the distance measuring component 4 includes a shell 42 with a cavity 43 inside. A distance measuring head 44 for sending a detection signal is arranged in the shell 42. The distance measuring head 44 specifically includes one of a photoelectric sensor and an acoustic wave sensor.

[0073] The free end 511 of the electric wire is inserted into the housing 42 and electrically connected to the distance measuring head 44, providing electric energy for the distance measuring head 44. When the housing 42 moves to a position away from the reel 5, the reel 5 rotates to release the wire, and the distance measuring head 44 is powered on to detect the height of clothes at different positions. On the contrary, when the housing 42 moves to a position close to the reel 5, the reel 5 reels the wire, and the distance measuring head 44 can still be powered on to detect the height of clothes at different positions during the reeling process. In this way, during the process of releasing and reeling the wire on the reel 5, the height of clothes at different positions can be detected multiple times, and comprehensive and specific clothing height data can be obtained.

[0074] Preferably, the washing machine can also simulate a schematic diagram of the current distribution of clothes inside the washing machine based on the detected height information. The user can grasp the status of the clothes in the washing machine in real time based on the simulated schematic diagram. Once the clothes are extremely unevenly distributed, the output prompt information can be controlled to make manual intervention corrections.

[0075] As another embodiment of the present invention, the reel 5 can also be used to retract the water inlet pipe 21, one end of the water inlet pipe 21 is connected to the water inlet 2, and the other end is connected to the spray assembly 6 integrated in the housing 42 to supply water to the spray assembly 6. Preferably, the spray assembly 6 has a spray head, which is rotatably arranged on the housing 42; more preferably, the spray head can rotate 360°.

[0076] During the movement of the housing 42 of the distance measuring component 4, the spraying component 6 is carried to move synchronously, and after the distance measuring head 44 detects the height information of the clothes, the spraying component 6 can be directly controlled to spray water to the corresponding position. The spraying component 6 can spray water to treat the clothes in a targeted manner according to the height of the clothes in real time and accurately, with high spraying efficiency and good spraying effect.

[0077] As an embodiment of the present invention, the present invention further provides a washing machine having a washing machine upper cover 1 as described in any of the above technical solutions. By providing the washing machine upper cover 1 of the present invention, the height of clothes at different positions in the washing machine can be accurately detected, and then the spraying program of the washing machine can be reasonably controlled according to the actual height of the clothes.

[0078] Specifically, the washing machine includes a controller electrically or communicatively connected to the driving component and the ranging component 4, and a spray component 6 connected to the controller. The controller controls the driving component to drive the ranging component 4 to move and detect the height of clothes at different positions in the washing machine, and controls the spray component 6 to spray water to the corresponding height position according to the detected height of clothes.

[0079] In this embodiment, the controller realizes the linkage between the driving component, the distance measuring component 4, and the spraying component 6. When the distance measuring component 4 detects that the height of the clothes is within the set threshold, it indicates that there are clothes at this position. At this time, the spraying component 6 is controlled to spray at this position, thereby ensuring the accuracy of the spraying and avoiding invalid spraying.

[0080] On the contrary, when the distance measuring component 4 detects that the height of the clothes is not within the set threshold, it indicates that there is no clothes at that position. At this time, there is no need to control the spraying component 6 to spray, so as to avoid the water flow spraying directly onto the inner barrel wall without contacting the clothes, thereby wasting water resources.

[0081] The present invention also provides a control method for a washing machine, comprising: presetting a barrel depth h0 of the washing machine; controlling a driving component to drive a ranging component to move and detect the height h of clothes at different positions in the washing machine; comparing the detected height h of clothes with the preset depth h0, and if h<h0, it is determined that clothes exist at the position, and controlling a spraying component to spray water toward the position in a directional manner.

[0082] Specifically, Figure 5 As shown, the control steps include:

[0083] S1, start;

[0084] S2, preset the barrel depth h0 of the washing machine;

[0085] S3, controlling the driving component to drive the distance measuring component 4 to move and detect the height h of clothes at different positions in the washing machine;

[0086] S4, determining whether the detected clothing height h is less than the preset washing machine barrel depth h0; if so, executing step S5; otherwise, executing step S7;

[0087] S5, determining that there is clothing at the location;

[0088] S6, control the spray assembly 6 to spray water toward the position;

[0089] S7, determine whether the detection is completed, if so, control the detection process to end, otherwise, return to step S3.

[0090] Among them, in step S7, the detection time or moving path of the distance measuring component 4 is preset. When the accumulated detection time reaches the preset detection time, or the distance measuring component 4 has completed the movement on the moving path, it is determined that the detection is completed.

[0091] In the control method of the washing machine of the present invention, the driving component drives the distance measuring component 4 to move, so that the distance measuring component 4 detects the distance from the upper cover 1 to different positions of the bottom end of the inner barrel during the activity, and then makes a comprehensive judgment on whether there are clothes in the barrel. When h<h0, it indicates that there are clothes at this position. At this time, water is controlled to be sprayed into this position, so that the spray water flow directly acts on the clothes, and the clothes are effectively sprayed and washed.

[0092] As an implementation of this embodiment, detecting the height of clothes at different positions in the washing machine includes: controlling the distance measuring component 4 to move from the outer circle track of the upper cover 1 to the inner circle track in sequence, controlling the reel of the distance measuring component to rotate and release the line during the movement, and powering on to detect the height h of clothes at different positions. After the detection is completed, the reel is controlled to reel in, and the distance measuring component 4 moves from the inner circle track to the outer circle track in sequence, and the height h of clothes at different positions can be detected by powering on during the movement.

[0093] In this embodiment, the distance measuring component 4 is controlled to move from the outer circle to the inner circle inside the upper cover 1 to detect the height of the clothes in the first cycle, and then move from the inner circle to the outer circle to detect the height of the clothes in the second cycle. The washing machine performs positioning spraying according to the detection result of the height of the clothes in the first cycle, and then waits for the completion of the detection of the height of the clothes in the second cycle, and then performs positioning spraying according to the detection result of the height of the clothes in the second cycle.

[0094] Alternatively, the washing machine determines the height of the clothes based on a comprehensive analysis of the clothes height detection result of the first cycle and the clothes height detection result of the second cycle, and performs spraying treatment in sequence according to the obtained heights.

[0095] Preferably, in this embodiment, the spray water inlet time and the spray water inlet intensity are negatively correlated with the detected clothing height h. For example, the smaller the detected clothing height h is, the higher the height of the clothing in the inner barrel is. At this time, the spray water inlet time is controlled to be longer and the spray water inlet intensity is stronger, so as to fully spray the clothing; on the contrary, the larger the detected clothing height h is, the lower the height of the clothing in the inner barrel is. At this time, the spray water inlet time is controlled to be shorter and the spray water inlet intensity is lower, so that the clothing at this position can be effectively sprayed to avoid excessive spraying and wasting water and electricity resources.

[0096] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
