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 positioning the spraying of clothes and improving the spraying accuracy.

[0011] Further, the upper end wall of the shell is movably connected to the track structure, and the spray head is arranged on the lower end wall opposite to the upper end wall of the shell;

[0012] Preferably, the spray head is rotatably disposed on the lower end wall.

[0013] Furthermore, the track structure is spirally extended from the outer circumference of the upper cover toward the center thereof, and the spray assembly can move along the spiral track structure and spray water toward clothing height positions corresponding to different positions of the spiral track structure.

[0014] Furthermore, the track structure includes a plurality of concentrically arranged tracks, the spraying components are respectively arranged on the plurality of tracks, and each spraying component can be moved respectively to spray water at clothing height positions corresponding to different positions of the plurality of tracks;

[0015] Alternatively, several circles of the track are transitionally connected by a connecting track, and the spray assembly can move on the multiple circles of the track through the connecting track to spray water toward the clothing height positions corresponding to different positions of the connecting track and the multiple circles of the track.

[0016] Furthermore, a reel for retracting a water inlet pipe is provided on the inner side of the upper cover, and the water outlet end of the water inlet pipe is connected to the spray assembly for supplying water to the spray assembly. When the spray assembly moves to a position away from the reel, the reel rotates to release the pipe, and the spray assembly discharges water to spray the water to different positions. When the reel retracts the pipe, it drives the spray assembly to move to a position close to the reel.

[0017] The present invention also provides a washing machine having a washing machine upper cover as described in any one of the above technical solutions.

[0018] A method for controlling a washing machine as described in the above technical solution comprises: controlling a distance measuring component to detect the height of clothes at different positions in the washing machine, locking the position where the clothes exist in the washing machine according to the detected height of the clothes, and controlling the activity of a spray component to spray water into the locked position;

DETAILED DESCRIPTION

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] like Figures 1 to 4 As shown, the present invention provides an upper cover 1 of a washing machine, which includes a controller, a distance measuring component 4 connected to the controller for detecting the height of clothes at different positions in the washing machine, and a spray component 6 movably arranged on the inner side of the upper cover 1 and connected to the controller. The controller controls the movement of the spray component 6 according to the height of clothes detected by the distance measuring component 4, so as to spray water into positions corresponding to different heights of clothes in the washing machine.

[0039] The controller is electrically connected or communicatively connected to the distance measuring component 4 and the spraying component 6. The distance measuring component 4 includes an acoustic sensor, 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 determines the height of the clothes by the reflection time and / or reflectivity of the light.

[0040] Specifically, the controller controls the ranging component 4 to detect the height of clothes at different positions in the washing machine, and the ranging component 4 sends the detected height of clothes to the controller in the form of an electrical signal or a communication signal; the controller receives the signal from the ranging component 4, and converts the received signal into clothing height information, and determines whether there are clothes at the current position according to the clothing information. If there are clothes, the spray component is controlled to move toward the side of the position and spray water to the position.

[0041] In the present invention, the controller can control the distance measuring component 4 to detect the height of clothes at different positions in the washing machine. The height of clothes reflects whether there are clothes at this position and the amount of clothes there. The controller controls the spray component 6 to move to the position where the clothes are present and spray water according to the detected height of clothes, so that the spray water flow can directly and accurately act on the clothes, effectively spray the clothes, and avoid the spray component 6 spraying water to the position where there are no clothes, causing waste of water and electricity resources.

[0042] As an embodiment of the present invention, Figure 1 As shown, the spray assembly 6 includes a spray head 61 rotatably arranged on the inner side of the upper cover, a driver connected to the spray head 61 for driving the spray head 61 to rotate, and the controller is connected to the driver for controlling the driver to drive the spray head 61 to rotate to positions corresponding to different clothing heights to spray water.

[0043] The spray head 61 is connected to the water inlet of the washing machine, and the water inlet is used to supply water to the spray head 61. The driver of this embodiment includes a motor arranged on the spray head 61.

[0044] Furthermore, in this embodiment, the spray head 61 can rotate 360 ​​degrees. The spray head 61 can be set at any position inside the upper cover 1, preferably, at the center area of ​​the upper cover 1, so as to ensure that the spray head 61 can rotate to any position of the inner barrel of the washing machine, so as to spray at various positions and cover a wide range.

[0045] In this embodiment, the distance measuring component 4 can be movably arranged on the inner side of the upper cover 1, and the distance measuring component 4 is movable and used to detect the height of clothes at different positions in the washing machine. The distance measuring component 4 sends the detected height of clothes to the controller in the form of an electrical signal or a communication signal; the controller receives the signal from the distance measuring component 4, and converts the received signal into the height information of clothes, and judges whether there is clothes at the current position according to the height information of clothes. If there is clothes, the driver drives the spray head 61 to move toward the current position side, and controls the water inlet waterway of the washing machine to connect the water supply, and the spray head 61 pressurizes the water flow and sprays water to the position where the clothes are currently located.

[0046] As another embodiment of the present invention, Figure 2 As shown, a track structure 3 is laid on the inner side of the upper cover 1, and the spray assembly 6 is movably arranged on the track structure 3. The controller controls the spray assembly 6 to move on the track structure 3 and spray water to positions corresponding to different clothing heights. Further, in this embodiment, the distance measuring assembly 4 is also movably arranged on the track structure 3, and the distance measuring assembly 4 moves on the track structure 3 to detect the clothing heights corresponding to different positions of the track structure 3.

[0047] Among them, the movement mode of the spray component 6 and the distance measuring component 4 includes: the spray component 6 and the distance measuring component 4 can be slidably arranged on the track structure 3; or, the spray component 6 and the distance measuring component 4 can be rollably arranged on the track structure 3.

[0048] 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.

[0049] 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 the adjacent horizontal tracks are connected through the vertical track. The spray component 6 and the ranging component 4 can move on the horizontal track and move to another horizontal track adjacent to it through the vertical track.

[0050] In this embodiment, a track structure 3 is provided on the inner side of the upper cover 1, so that the spray assembly 6 and the distance measuring assembly 4 can move on the track structure 3, and the moving positions are different, and the corresponding positions in the inner barrel are also different. In this way, the distance measuring assembly 4 can comprehensively detect the heights of clothes at different positions in the inner barrel during the movement of the track structure 3; the spray assembly 6 can spray water to the positions corresponding to the different heights of clothes in the inner barrel during the movement of the track structure 3.

[0051] As an embodiment of the present invention, Figure 2 As shown, the spray assembly 6 includes a housing 42 movably arranged on the track structure 3. The housing 42 has a driver connected to the controller and a spray head 61. The controller controls the driver to drive the housing 42 to move on the track structure 3 and controls the spray head 61 to spray water to different positions.

[0052] Furthermore, the distance measuring component 4 is also arranged on the shell 42, and the distance measuring component 4 includes a distance measuring head 44, which is arranged on the shell 42. The distance measuring head 44 specifically includes one of a photoelectric sensor and an acoustic wave sensor.

[0053] In this embodiment, the spray head 61 and the distance measuring head 44 are integrated on the housing 42. When the controller controls the driver to drive the housing 42 to move on the track structure 3, the spray head 61 and the distance measuring head 44 move synchronously with the housing 42. After the distance measuring head 44 detects the height information of the clothes, the spray head 61 can be directly controlled to spray water to the corresponding position. The spray head 61 can spray water to treat the clothes in real time and accurately according to the height of the clothes, with high spray efficiency and good spray effect.

[0054] As an implementation method of this embodiment, the upper end wall of the shell 42 is movably connected to the track structure 3. The spray head 61 is arranged on the lower end wall opposite to the upper end wall of the shell 42. The lower end wall of the shell 42 is arranged toward the bottom of the inner barrel, and the spray head 61 is arranged on the lower end wall of the shell 42, so that the spray head 61 can spray water into the inner barrel.

[0055] Preferably, the spray head 61 is rotatably disposed on the lower end wall of the housing 42. Further preferably, the spray head 61 can be rotated 360°; thus, by moving the housing 42, the spray head 61 can be moved to the position directly above the clothes, and then the spray head 61 can be controlled to rotate, and the direction of the spray head 61 can be accurately adjusted, so as to further accurately spray water to the position where the clothes are in the inner barrel.

[0056] In this embodiment, a roller 41 is provided on the upper end wall of the shell 42 and is in rolling contact with the track structure 3. The shell 42 also has a motor, which is connected to the roller 41 to drive the roller 41 to roll on the track structure 3, drive the shell 42 to move, detect the height of clothes at different positions, and spray water into the position where the clothes are present.

[0057] Preferably, a plurality of groups of rollers 41 may be provided on the housing 42 to ensure that the housing 42 can roll smoothly on the track structure 3 .

[0058] 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 .

[0059] As an embodiment of the present invention, the track structure 3 is spirally extended from the outer circumference of the upper cover toward the center thereof, and the spray assembly 6 can move along the spiral track structure 31 and spray water to the clothing height positions corresponding to different positions of the spiral track structure 31. In this embodiment, the distance measuring assembly 4 can also move along the spiral track structure 31 and detect the clothing height corresponding to different positions of the spiral track structure 31.

[0060] Specifically, the distance measuring component 4 and the spraying component 6 first start from one end of the spiral track structure 31 close to the outer periphery of the upper cover 1 and gradually move 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. During the detection process of the distance measuring component 4, once the detected height of the clothes is within the preset threshold range, it indicates that there are clothes at the current position. After controlling the spraying component 6 to move to the vicinity of the position where the clothes are present, water is sprayed into the position to accurately spray the clothes.

[0061] In this embodiment, the spiral track structure 31 is smooth and unobstructed, so that the distance measuring component 4 and the spraying component 6 move more smoothly, and the detection and spraying efficiency are improved on the basis of ensuring the accuracy of the detection results and the spraying position.

[0062] When the distance measuring component 4 and the spray component 6 move to the center position of the spiral track structure 31, the distance measuring component 4 and the spray component 6 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; and the spray component 6 can be controlled to spray water into the position where the clothes are again, so as to improve the spray treatment effect on the clothes.

[0063] As an embodiment of the present invention, the track structure 3 includes a plurality of concentrically arranged tracks, the spraying components 6 are respectively provided on the plurality of tracks, and each spraying component 6 can move respectively and spray water to the clothing height positions corresponding to different positions of the plurality of tracks. Preferably, the distance measuring components 4 are also respectively provided on the plurality of tracks, and each distance measuring component 4 moves respectively to detect the clothing height corresponding to different positions of the plurality of tracks.

[0064] Specifically, the distance measuring components 4 and the spraying components 6 on several circles of tracks can be controlled to move respectively. And the moving speed and moving time of each distance measuring component 4 and the spraying component 6 can be adjusted according to actual conditions.

[0065] For example: control the moving speed of the distance measuring component 4 and the spraying component 6 on the outer ring track to be greater than the moving speed of the distance measuring component 4 and the spraying component 6 on the inner ring track, so that the distance measuring component 4 and the spraying component 6 on the outer ring track and the distance measuring component 4 and the spraying component 6 on the inner ring track start moving at the same time, and complete the detection of a whole cycle of the corresponding tracks within the same time.

[0066] For another example: when the moving speeds of the distance measuring components 4 and the spraying components 6 are the same, the distance measuring components 4 and the spraying components 6 on the outer ring track are controlled to start moving first, and after moving for a period of time, the distance measuring components 4 and the spraying components 6 on the inner ring track are controlled to start moving. In this way, the moving time of each distance measuring component 4 and the spraying component 6 is reasonably controlled, and repeated detection and spraying of the distance measuring components 4 and the spraying components 6 on the inner ring track are avoided.

[0067] Specifically, Figure 3 As 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 and the spraying component 6 can be moved 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 and the spraying component 6, 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, and water can be sprayed to the position where the clothes are present.

[0068] 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 ​​.

[0069] The distance measuring component 4 and the spraying component 6 can move from the outermost track 32 to the secondary outer track 33 through the first connecting track 35, and then move from the secondary outer track 33 to the innermost track 34 through the second connecting track 36. During the movement of the distance measuring component 4 and the spraying component 6, the height of the clothes in the inner barrel corresponding to each position of the outermost track 32, the secondary outer track 33, the innermost track 34, the first connecting track 35, and the second connecting track 36 can be detected in real time, and water can be sprayed on the position where the clothes are present.

[0070] 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.

[0071] 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.

[0072] 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 and the spraying component 6 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 and the spraying component 6 on different tracks, but also greatly simplify the track laying layout.

[0073] As another embodiment of the present invention, a reel 5 for retracting a water inlet pipe 21 is provided on the inner side of the upper cover 1. The water outlet end of the water inlet pipe 21 is connected to the spray assembly 6 for supplying water to the spray assembly 6. When the spray assembly 6 moves to a position away from the reel 5, the reel 5 rotates to release the pipe, and the spray assembly 6 discharges water to spray the water to different positions; when the reel 5 retracts the pipe, it drives the spray assembly 6 to move to a position close to the reel 5.

[0074] Furthermore, the reel 5 can also automatically reel the wire 51 and automatically unwind the wire. The free end 511 of the wire is connected to the distance measuring component 4 for powering 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 unwind 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 rewinds the wire, it drives the distance measuring component 4 to move to a position close to the reel 4.

[0075] Furthermore, the free end 511 of the 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. The water outlet end of the water inlet pipe 21 is connected to the water source, and the water outlet end of the water inlet pipe 21 is inserted into the housing 42 and connected to the spray head 61, providing electric energy water flow for the spray head 61.

[0076] When the housing 42 moves to a position away from the reel 5, the reel 5 rotates to release the line, and the distance measuring head 44 is powered on to detect the height of the 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 line, and the distance measuring head 44 can still be powered on to detect the height of the clothes at different positions during the reeling process. In this way, during the process of the reel 5 releasing and reeling the line, the height of the clothes at different positions can be detected multiple times, and comprehensive and specific clothing height data can be obtained.

[0077] 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.

[0078] Specifically, Figure 2 , Figure 3 and Figure 4 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 and the water inlet for spraying, the reel 5 is in a reeled state, and the ranging component 4 and the spray head 61 are integrated on the shell 42 and are located on the outer peripheral edge of the inner side of the upper cover 1.

[0079] When it is necessary to detect the height of the clothes in the washing machine and spray water, the reel 5 unwinds the line and the tube, and the shell 42 integrated with the distance measuring component 4 and the spray head 61 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.

[0080] When it is necessary to detect the height of the clothes in the washing machine and spray water, the shell 42 integrated with the distance measuring component 4 and the spray head 61 is reversed and retracted to the outer peripheral edge of the inner side of the upper cover 1, and the reel 5 reels in the line and the tube, and when reeling in the line, the shell 42 is pulled back along the "innermost circle track 34-third connecting track 37-outermost circle track 32-third connecting track 37".

[0081] In this embodiment, by setting up a reel 5 to retract the electric wire 51 and the water inlet pipe 21, it is possible to continuously provide electric energy to the distance measuring component 4 during movement and continuously supply water to the sprinkler head 61, and also provide traction force for the distance measuring component 4 and the sprinkler head 61 when they are retracted and reset. While rewinding the electric wire 51 and the water inlet pipe 21, the resetting of the distance measuring component 4 and the sprinkler head 61 is assisted.

[0082] 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.

[0083] In this embodiment, the distance measuring component 4 and the spraying component 6 are linked by the controller. 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 that position. At this time, the spraying component 6 is controlled to spray at that position, thereby ensuring the accuracy of the spraying and avoiding invalid spraying.

[0084] 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.

[0085] The present invention also provides a control method for a washing machine, which controls a distance measuring component 4 to detect the height of clothes at different positions in the washing machine, locks the position of the clothes in the washing machine according to the detected height of the clothes, and controls a spray component 6 to move and spray water to the locked position.

[0086] Preferably, the distance measuring component 4 and the spray component 6 are controlled to move synchronously on the inner side of the upper cover 1, and during the movement, the distance measuring component 4 is controlled to detect and lock the position where the clothes are present, and the spray component 6 is controlled to spray water toward the locked position; or, the distance measuring component 4 is controlled to move on the inner side of the upper cover, and detect and lock the position where the clothes are present, and the spray component 6 is controlled to rotate toward the locked position and spray water.

[0087] In the control method of the washing machine of the present invention, the spray assembly 6 is controlled to move toward the locked position where the clothes are present, so that the spray water flow of the spray assembly 6 can directly and accurately act on the clothes. The spray control method is simple and the positioning spray is accurate.

[0088] Specifically, a control method of the present invention is as follows: Figure 5 As shown, the control steps include:

[0089] S1, start;

[0090] S2, preset the barrel depth h0 of the washing machine;

[0091] 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;

[0092] 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;

[0093] S5, determining that there is clothing at the location;

[0094] S6, control the spray assembly 6 to spray water toward the position;

[0095] S7, determine whether the detection is completed, if so, control the detection process to end, otherwise, return to step S3.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.
