[0053] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0054] When an existing drum washing machine is currently turned on and the door is closed to run the washing program, the clothes in the drum will be squeezed against the door. The embodiments of the present invention provide a control method and a drum washing machine. By obtaining the distance between the door and the front panel of the washing machine when the door is closed, it is determined whether the door is squeezed, thereby reminding the user to take corresponding measures to deal with the clothes in the drum.

[0055] The following is combined with Figure 1 -Attached Figure 3 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0056] Example

[0057] like Figure 1-Figure 2 As shown, this embodiment provides a control method for a drum washing machine, wherein the drum washing machine includes a front panel, a clothing loading port is formed on the front panel, and a door body is hingedly connected to the clothing loading port. The method includes:

[0058] Obtaining the distance between the door body and the front panel when the door body is closed, and determining whether to output a reminder instruction based on the distance between the door body and the front panel;

[0059] The reminder instructions include adjustment instructions for reminding the user to adjust the amount of clothes and / or adjustment instructions for adjusting the state of clothes.

[0060] In the embodiment of the present invention, by obtaining the distance between the door body and the front panel of the washing machine when the door body is closed, it is determined whether the door body is squeezed, thereby reminding the user to handle the clothes in the drum accordingly.

[0061] Furthermore, the door body includes a top and a bottom in the height direction;

[0062] Determine whether to output a reminder command based on the distance between the door and the front panel, including:

[0063] Whether to output a reminder instruction is determined according to the distance between the top of the door body and the front panel and the distance between the bottom of the door body and the front panel.

[0064] That is, in the embodiment of the present invention, by obtaining the distance between different positions of the door body and the front panel, different problems existing in the clothes in the inner drum can be determined, and the user is reminded to perform corresponding processing according to the different problems determined.

[0065] Furthermore, determining whether to output a reminder instruction based on the distance between the top of the door body and the front panel and the distance between the bottom of the door body and the front panel includes:

[0066] If the distance between the top of the door body and the front panel is greater than or equal to the first threshold, and the distance between the bottom of the door body and the front panel is less than the first threshold, a first reminder instruction is issued;

[0067] If the distance between the top of the door body and the front panel is less than the first threshold, and the distance between the bottom of the door body and the front panel is greater than or equal to the first threshold, a second reminder instruction is issued;

[0068] If the distance between the top of the door body and the front panel is greater than or equal to the first threshold, and the distance between the bottom of the door body and the front panel is greater than or equal to the first threshold, a third reminder instruction is issued;

[0069] The first reminder instruction includes an adjustment instruction for reminding the user to adjust the status of clothes, the second reminder instruction includes an adjustment instruction for reminding the user to adjust the quantity of clothes, and the third reminder instruction includes an adjustment instruction for reminding the user to adjust the status of clothes and the quantity of clothes. The first threshold is the maximum allowable distance value between the door body and the front panel.

[0070] Preferably, the first threshold is set to 25 mm.

[0071] When the distance between the top of the door body and the front panel is greater than or equal to a first threshold value, but the distance between the bottom of the door body and the front panel is less than the first threshold value, it can be determined that the clothes in the inner drum have clumped together {when the clothes in the inner drum are clumped together and the number is small, the clumped clothes will squeeze the top position of the door body, thereby causing the top of the door body to move to the side away from the front panel}.

[0072] When the distance between the top of the door body and the front panel is less than a first threshold value, but the distance between the bottom of the door body and the front panel is greater than or equal to the first threshold value, it can be determined that the amount of clothes in the inner drum is too large {when the amount of clothes in the inner drum is too large and not clumped, the excessive amount of clothes will squeeze the bottom position of the door body, thereby causing the bottom of the door body to move to the side away from the front panel}.

[0073] When the distance between the top of the door body and the front panel is greater than or equal to a first threshold value and the distance between the bottom of the door body and the front panel is greater than or equal to the first threshold value, it can be determined that the amount of clothes in the inner drum is too much and has clumped together. When the excessive amount of clothes clumps together, it will squeeze the top and bottom positions of the door body at the same time, thereby causing the entire door body to move to the side away from the front panel.

[0074] In an embodiment of the present invention, by discovering that clothes in different situations {clothes clumping and / or too much clothes} will squeeze different positions of the door body, the distance between different positions of the door body and the front panel is obtained in a targeted manner, so that when the door body is squeezed, the clothes in the inner drum are processed in a targeted manner.

[0075] In any of the above embodiments, the drum-type washing machine has a washing program;

[0076] The control method also includes:

[0077] Under the washing program, the distance between the door body and the front panel is obtained, and the output of the reminder instruction is determined based on the distance between the door body and the front panel.

[0078] That is, in the embodiment of the present invention, it is preferred to obtain the distance between the door body and the front panel during the washing program, thereby reducing the pressure of the clothes on the door body while ensuring the washing effect of the clothes.

[0079] It is worth mentioning that the reason why the distance between the door body and the front panel is obtained during the washing process in the embodiment of the present invention is that the squeezing of the door body by the clothes is more serious after absorbing water.

[0080] Furthermore, the control method further includes:

[0081] In the washing program, if it is determined to output the reminder instruction, the drainage program is entered to drain the washing water in the clothes processing drum, and at the same time, the driving motor for driving the clothes processing drum to rotate is turned off and the door is unlocked.

[0082] It is worth noting that the drainage program mentioned in the embodiment of the present invention is not a dehydration program for dehydrating clothes {the dehydration program will be introduced separately below}, but a program for draining the washing water in the drum.

[0083] In any of the above embodiments, the drum-type washing machine further has a dehydration program;

[0084] The control method also includes:

[0085] In the dehydration process, the inner drum is controlled to speed up to the target speed, and the change in the distance between the door body and the front panel in each of the two adjacent time units during the speed increase process is obtained. The inner drum is controlled to continue to speed up or down according to the change in the distance between the door body and the front panel in the two adjacent time units.

[0086] The drum washing machine in the embodiment of the present invention can reflect the fluctuation size of the clothes during dehydration by obtaining the change in the distance between the door body and the front panel during the dehydration program {if the clothes are unevenly distributed during the dehydration program, the door body will be continuously and intermittently squeezed, causing the door body to continuously shake back and forth. Therefore, it is necessary to monitor the change in the distance between the door body and the front panel to reflect the status of the clothes in the drum}.

[0087] Specifically, controlling the inner drum to continue increasing or decreasing speed according to the distance change between the door body and the front panel in two adjacent time units includes:

[0088] If the distance change between the door body and the front panel in each of two adjacent time units is greater than or equal to the second threshold, the inner drum is controlled to slow down;

[0089] If the distance change between the door body and the front panel in at least one of two adjacent time units is less than a second threshold, the inner drum is controlled to continue to increase its speed.

[0090] If, in two adjacent time units, the distance change between the door and the front panel in each of the two adjacent time units is greater than or equal to the second threshold, it means that the clothes in the inner drum fluctuate greatly during dehydration and the speed needs to be reduced.

[0091] If the distance change between the door body and the front panel in at least one of two adjacent time units is less than a second threshold, the inner drum may be controlled to continue to increase its speed.

[0092] Preferably, the second threshold is set to 5 mm, and during the speed increase process, a change of every 10 revolutions is regarded as a time unit.

[0093] It is worth noting that the process of obtaining the change in the distance between the door body and the front panel in each of two adjacent time units during the speed-up process is carried out in real time, that is, the change in the distance between the door body and the front panel in each of two adjacent time units is obtained in real time during the dehydration program.

[0094] In any of the above embodiments, the method for controlling the speed reduction of the inner drum includes:

[0095] The inner drum is controlled to slow down to the eccentric weighing detection stage, the target speed is determined based on the eccentricity value and weighing value obtained in the eccentric weighing detection stage, and the speed is increased to the target speed after the eccentric weighing stage is completed.

[0096] The inner drum in the embodiment of the present invention controls its speed to the eccentric weighing detection stage when slowing down to redistribute and weigh the clothes, and determines the target speed based on the weighing results, and then re-speeds up, and flushes and records the change in the amount between the door body and the front panel during the speed-up process, thereby making the speed-up dehydration process more stable.

[0097] It is worth noting that the above-mentioned target speed is determined by the weighing result of the eccentric weighing detection stage, that is, the target speed of the speed-up process is determined according to the weighing value determined in the eccentric weighing detection stage before the speed-up stage.

[0098] Furthermore, the number of eccentric weighing detection stages performed in the dehydration program is obtained;

[0099] If the number of executions of the eccentric weighing detection stage is greater than the third threshold, and the change in the distance between the door body and the front panel in each of the two adjacent time units in the current speed-up process is still greater than or equal to the second threshold, a first reminder instruction is issued.

[0100] Preferably, the third threshold is three times.

[0101] That is, if the distance between the door and the front panel still changes greatly after the dehydration program has been run for more than three times, it means that the clothes in the inner drum have become seriously clumped and cannot be evenly distributed by mechanical means. At this time, a first adjustment instruction is issued to remind the user to adjust the status of the clothes, so as to distribute the clothes in the inner drum through manual intervention.

[0102] like Figure 3 As shown, a second aspect of an embodiment of the present invention further provides a drum-type washing machine, which adopts the above-mentioned control method and includes:

[0103] A front panel 1 is provided with a clothing loading port;

[0104] Door body 2, door body 2 is hinged at the clothing loading port;

[0105] Detection component 3, detection component 3 is provided between door body 2 and front panel 1, and is used to detect the distance between door body 2 and front panel 1 when door body 2 is closed;

[0106] A control module is used to determine whether to output a reminder instruction according to the distance between the door body 2 and the front panel 1;

[0107] The reminder instructions include instructions to remind the user to adjust the amount of clothes and instructions to adjust the status of clothes.

[0108] In an embodiment of the present invention, a detection component 3 is set between the front panel 1 and the door body 2, which can detect the distance between the door body 2 and the front panel 1 when the door body 2 is closed. The control module can determine whether to output a reminder instruction based on the distance between the door body 2 and the front panel 1, thereby determining whether to remind the user to process the clothes in the drum based on the distance between the door body 2 and the front panel 1.

[0109] Furthermore, the detection component 3 is provided at the top position between the door body 2 and the front panel 1 and / or at the bottom position between the door body 2 and the front panel 1, and is used to detect the distance between the top of the door body 2 and the front panel 1 and / or the distance between the bottom of the door body 2 and the front panel 1;

[0110] The control module is used to determine whether to output a reminder instruction according to the distance between the top of the door body 2 and the front panel 1 and / or according to the distance between the bottom of the door body 2 and the front panel 1.

[0111] Specifically, such as Figure 3 As shown, the detection component 3 includes a first detection component 31 and a second detection component 32;

[0112] The first detection component 31 includes a first proximity switch 311 and a first magnet 312 provided at the top between the door body 2 and the front panel 1 , and the second detection component 32 includes a second proximity switch 321 and a second magnet 322 provided at the bottom between the door body 2 and the front panel 1 ;

[0113] The drum-type washing machine further includes a first detection circuit and a second detection circuit electrically connected to the control module. When the distance between the first proximity switch 311 and the first magnet 312 is greater than a first threshold, the first detection circuit may be turned on. When the distance between the second proximity switch 321 and the second magnet 322 is greater than the first threshold, the second detection circuit may be turned on.

[0114] When the first detection circuit is turned on, the control module outputs a first reminder instruction, and when the second detection circuit is turned on, the control module outputs a second reminder instruction.

[0115] Preferably, the first threshold is 25 mm.

[0116] It is worth noting that the normal distance between the door body 2 and the front panel 1 is 20mm, with a tolerance of ±5mm. That is, when the distance between the door body 2 and the front panel 1 is within the range of 20±5mm, the door body 2 can be considered to be in a normal offset range and has not deviated significantly. When the distance between the door body 2 and the front panel 1 is greater than or equal to 25mm, it means that the door body 2 is significantly off-center, which reflects the condition of the inner drum clothing.

[0117] In any of the above embodiments, the first proximity switch 311 is provided on the top of the door body 2 , and the first magnet 312 is provided on the front panel 1 and is opposite to the first proximity switch 311 ;

[0118] The second proximity switch 321 is disposed at the bottom of the door body 2 , and the second magnet 322 is disposed on the front panel 1 and is opposite to the second proximity switch 321 .

[0119] Furthermore, the drum-type washing machine includes an inner drum that is rotatably arranged;

[0120] The first proximity switch 311 and the first magnet 312 are disposed opposite to each other in the axial direction of the inner cylinder, and the second proximity switch 321 and the second magnet 322 are disposed opposite to each other in the axial direction of the inner cylinder.

[0121] In the embodiment of the present invention, the proximity switch and the magnet are arranged to be opposite to each other in the axis direction of the inner cylinder, so that the measurement accuracy of the distance between the door body and the front panel can be improved.

[0122] Other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow from the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
