Description

Technical Field

[0001] The present application belongs to the technical field of smart home appliances, and specifically relates to a barrel collision judgment method, device, equipment and storage medium. Background Art

[0002] At present, there are few methods for sensing the eccentricity of pulsator washing machines. In order to prevent the pulsator washing machine from violently hitting the barrel during high-speed dehydration, a mechanical barrel-hitting switch is generally used. That is, when the inner barrel rotates and causes the outer barrel to move, it will touch the barrel-hitting switch. After being acted upon by external force, the circuit is connected, thereby determining that a barrel-hitting has occurred.

[0003] However, the above method can only determine that the pulsator washing machine has a barrel collision when the outer barrel touches the barrel collision switch. If the outer barrel does not touch the barrel collision switch during the barrel collision process, it will lead to inaccurate judgment and cannot timely control the pulsator washing machine to perform the barrel collision process, affecting the user experience.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0063] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0064] Currently, there are few methods for sensing the eccentricity of a pulsator washing machine. When the pulsator washing machine is dehydrating at high speed, if there is no eccentricity, the outer drum of the pulsator washing machine will not shake obviously during the dehydration process; if there is eccentricity, the outer drum of the pulsator washing machine will make irregular elliptical motions during the dehydration process, and may even cause a collision with the drum.

[0065] The prior art uses a mechanical barrel bump switch to prevent a pulsator washing machine from barrel bumping during high-speed dehydration. When the inner barrel rotates and causes the outer barrel to move, it will touch the barrel bump switch. After being acted upon by an external force, the barrel bump switch will connect the circuit, thereby determining that a barrel bump has occurred. However, if the outer barrel does not touch the barrel bump switch during the barrel bump process, the above method will result in inaccurate judgment, and the pulsator washing machine will not be able to be controlled to perform a barrel bump in time, affecting the user experience.

[0066] The present application provides a barrel collision judgment method, which judges whether a barrel collision occurs in a clothing processing device according to the relationship between the capacitance value obtained by the capacitance sensor of the clothing processing device during the dehydration process and the capacitance threshold value when the barrel collision just occurs. Through the above method, the barrel collision judgment is more accurate, the barrel collision processing can be carried out in time, and the user experience is improved at the same time.

[0067] Next, the technical solution shown in the present application is described in detail through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0068] Figure 1 A flowchart of a barrel collision judgment method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0069] S101. When the clothes processing device enters a dehydration program, a plurality of capacitance values ​​in each time period are obtained according to a preset time interval.

[0070] In this step, the preset time interval is determined according to the different dehydration stages in the dehydration program. The rotation speed of the clothing processing device is different in different dehydration stages. The later the dehydration stage is, the higher the rotation speed is, and the more likely the barrel collision phenomenon will occur. Therefore, the later the dehydration stage is, the shorter the corresponding preset time interval is. The capacitance value is determined by the distance from the outer barrel of the clothing processing device to the housing.

[0071] The capacitance value is determined by the distance between the outer tub of the laundry processing device and the housing. The capacitance value is inversely proportional to the distance between the outer tub of the laundry processing device and the housing, that is, the closer the distance between the outer tub of the laundry processing device and the housing is, the greater the capacitance value is.

[0072] Specifically, in the high-speed dehydration stage of the clothes processing device, in order to avoid the outer barrel not contacting the barrel bumping switch during the barrel bumping process, so that the clothes processing device can not timely identify the clothes processing device barrel bumping, this embodiment uses the capacitance value to obtain the distance between the outer barrel of the clothes processing device and the housing, and judges whether the clothes processing device barrel bumps based on this.

[0073] Specifically, when it is detected that the clothes treating device enters the dehydration program, a plurality of continuous capacitance values ​​detected by the capacitance sensor in each time period are acquired at preset time intervals.

[0074] Furthermore, in order to increase the accuracy of obtaining the capacitance value, multiple capacitance sensors may be used to obtain average capacitance values, and then whether a barrel collision occurs may be determined based on the average capacitance value.

[0075] S102: Determine whether the laundry processing device hits a tub based on the relationship between the capacitance value and the capacitance threshold.

[0076] In this step, the capacitance threshold is a pre-acquired capacitance value when the outer tub of the laundry processing device collides with the housing.

[0077] Furthermore, when the obtained capacitance value is greater than or equal to the capacitance threshold, it means that the outer barrel and the casing of the clothing processing device collide at this time, and further corresponding processing needs to be performed on the collision barrel.

[0078] Exemplarily, the capacitance value detected by the capacitance sensor is 30, the capacitance threshold is 28, and the capacitance value 30 is greater than the capacitance threshold 28, and it is determined that the outer barrel and the casing of the laundry processing device collide.

[0079] It should be noted that the capacitance value is not only affected by the distance between the outer barrel and the casing of the clothing processing device, but also by factors such as the medium and area between the outer barrel and the casing. During the dehydration process, the water thrown out of the clothes will be discharged through the overflow port of the casing, so the thrown out water also affects the capacitance value detected by the capacitance sensor. Therefore, in order to make the clothing processing device more accurate in judging whether the clothing processing device has hit the barrel based on the capacitance value, a comprehensive judgment is made on whether the clothing processing device has hit the barrel based on the acquisition of multiple capacitance values ​​in each time period and the capacitance values ​​corresponding to the multiple time periods. The specific operation process of how to comprehensively judge whether the clothing processing device has hit the barrel based on the multiple capacitance values ​​in each time period and the capacitance values ​​corresponding to the multiple time periods will be described in the subsequent embodiments, and will not be described in detail here.

[0080] S103: If yes, control the clothes processing equipment to perform a barrel collision processing operation.

[0081] In this step, when it is determined that the capacitance value is greater than the capacitance threshold, it means that the clothing processing device sends a barrel collision signal, and then controls the clothing processing device to perform a barrel collision processing operation.

[0082] In a possible implementation, when it is determined based on the capacitance value that the clothing processing device has collided with the barrel, the clothing processing device is controlled to pause the dehydration program, and the clothing processing device is shaken to evenly distribute the clothing in the barrel.

[0083] Optionally, after controlling the clothes processing device to pause the dehydration program, the clothes processing device can also be controlled to rotate at a lower speed to redistribute the clothes in the barrel.

[0084] The present application provides a barrel collision judgment method, which judges whether a barrel collision occurs in a clothing processing device according to the relationship between the capacitance value obtained by the capacitance sensor of the clothing processing device during the dehydration process and the capacitance threshold value when the barrel collision just occurs. Through the above method, the barrel collision judgment is more accurate, the barrel collision processing can be carried out in time, and the user experience is improved at the same time.

[0085] Figure 2 A flowchart of a barrel collision judgment method provided in an embodiment of the present application Figure 2 The embodiment of the present application provides a detailed description of the operation steps of how to determine whether a barrel collision occurs based on the magnitude relationship of the capacitance values. Figure 2 As shown, the method includes:

[0086] S201. Obtain a magnitude relationship between the multiple capacitance values ​​and a capacitance threshold.

[0087] In this step, considering the effect of water thrown out of the clothes during the dehydration process on the capacitance detected by the capacitive sensor, this embodiment determines whether the clothing processing device hits the barrel based on multiple capacitance values ​​in each of multiple time periods.

[0088] Specifically, the relationship between multiple capacitance values ​​and capacitance thresholds in each of multiple time periods is obtained to determine whether the clothing processing device hits the barrel at the moment corresponding to the capacitance value, and then based on the number of times the barrel hits occur and whether the barrel hits are continuous, it is determined whether the barrel hit of the clothing processing device is affected by the thrown-out water, that is, whether to control the clothing processing device to perform the barrel hit process.

[0089] S202: If the capacitance values ​​within a single time period are all greater than or equal to the capacitance threshold, it is determined that the laundry processing device has hit the barrel.

[0090] In this step, when the clothes in the barrel of the clothing processing device are greatly eccentric, causing the clothing processing device to hit the barrel, the outer barrel of the clothing processing device will be displaced greatly. If the outer barrel of the clothing processing device collides with the casing at this time, then in each dehydration stage, the speed of the clothing processing device continues to increase, the displacement of the outer barrel continues to increase, and the outer barrel continues to collide with the casing.

[0091] Specifically, when each capacitance value obtained by the capacitance sensor in a single time period is greater than or equal to the capacitance threshold, it is determined that the judgment result of the clothing processing device hitting the barrel at this time is not affected by the swung out water, that is, the clothing processing device hits the barrel at this time, and the clothing processing device needs to be controlled to perform the barrel collision processing.

[0092] S203: If the capacitance value in each time period is less than the capacitance threshold, it is determined that the clothing processing device does not collide with the barrel.

[0093] In this step, if you want to determine that the clothing processing device has not hit the barrel, you need to confirm that the clothing processing device has not hit the barrel in each time period, that is, judge that the clothing processing device has not hit the barrel based on multiple capacitance values ​​in each time period in multiple time periods.

[0094] Specifically, when the capacitance value in each time period is less than the capacitance threshold, it means that during the dehydration process of the clothing processing device, the outer barrel of the clothing processing device and the casing have not collided, and the clothing processing device can continue to be controlled to perform the dehydration operation.

[0095] It should be noted that, although the capacitance value detected by the clothing treatment device at this time is affected by the water swung out of the clothing, causing the capacitance sensor to detect a larger capacitance value, all capacitance values ​​at this time are smaller than the capacitance threshold, that is, excluding the influence of the water swung out of the clothing, the capacitance value should be smaller, that is, smaller than the capacitance threshold. It can be explained that, despite the influence of the water swung out of the clothing, as long as the capacitance value in each time period is smaller than the capacitance threshold, it can be determined that the clothing treatment device has not hit the barrel.

[0096] S204. If there is a capacitance value greater than the capacitance threshold among the capacitance values ​​in each time period, obtain the interval time between two capacitance values ​​that are continuously greater than or equal to the capacitance threshold from the capacitance values ​​in each time period, and determine whether the clothing processing device has a barrel collision based on the interval time.

[0097] In this step, the interval time is used to determine whether the barrel bumps corresponding to two capacitance values ​​that are continuously greater than or equal to the capacitance threshold are continuous. That is, if the interval time is less than the time threshold, it means that the barrel bumps corresponding to two capacitance values ​​that are continuously greater than or equal to the capacitance threshold are continuous.

[0098] Furthermore, during the dehydration process, the water thrown out between the outer barrel and the housing also affects the capacitance value, that is, the capacitance value is too large. When the clothing processing device hits the barrel, the capacitance value will continue to be greater than the capacitance threshold, that is, there are multiple consecutive barrel hits; if affected by other factors, the interval between capacitance fluctuations is longer or the capacitance value that is continuously greater than the capacitance threshold will decrease and stabilize later.

[0099] Therefore, in order to more accurately determine whether the laundry processing device has hit the barrel, the number of consecutive barrel hits is recorded, and whether the laundry processing device has hit the barrel is determined based on the number of consecutive barrel hits. The specific operations are:

[0100] From the intervals, obtain a target interval that is less than a time threshold, obtain a target time period corresponding to the target interval, and obtain the number of target intervals in each target time period;

[0101] If the number is greater than or equal to the first number, it is determined that the clothes processing device has hit the barrel.

[0102] Furthermore, when the number is less than the first number, it means that the number of consecutive barrel collisions in each target time period is not large, that is, the capacitance value is likely to be affected by other factors, and the clothing processing device has not collided with the barrel. However, in order to further ensure and prevent missed judgments, if multiple time periods are judged to have continuous barrel collisions based on the capacitance value, it is also judged that the clothing processing device has collided with the barrel at this time. The specific process is:

[0103] If the number is less than the first number, the number of the target time periods is obtained, and if the number is greater than or equal to the second number, it is determined that the laundry processing device sends a barrel collision.

[0104] The present application provides a barrel collision judgment method, which judges whether the barrel collision corresponding to the two capacitance values ​​is a continuous barrel collision according to the interval time between two capacitance values ​​that are continuously greater than the capacitance threshold in a single time period, and judges whether the clothing processing device has a barrel collision according to the number of continuous barrel collisions in a single time period and the number of time periods in which continuous barrel collisions occur. Through the above method, the barrel collision judgment is more prepared, avoiding the extension of the dehydration program or the harm of barrel collision due to misjudgment.

[0105] Figure 3 A flowchart of a barrel collision judgment method provided in an embodiment of the present application Figure 3 The embodiment of the present application provides a detailed description of how to select the corresponding barrel collision processing operation steps according to the capacitance value. Figure 3 As shown, the method includes:

[0106] S301. If the capacitance values ​​within a single time period are all greater than or equal to the capacitance threshold, control the clothing processing device to send a prompt message.

[0107] In this step, the frequency of multiple capacitance values ​​in each of multiple time periods being greater than the capacitance threshold can be used to indicate the magnitude of the clothing eccentricity value, that is, it can reflect the degree of entanglement of the clothing in the barrel.

[0108] Furthermore, if the clothes are slightly entangled, the clothes treatment device can make the clothes in the barrel evenly distributed by a simple barrel bumping operation; if the clothes are significantly entangled, the clothes treatment device cannot ensure that the clothes in the barrel are evenly distributed by a simple barrel bumping operation. Therefore, other processing operations are required.

[0109] Specifically, when it is determined that the clothing processing device hits the barrel, and the capacitance values ​​in a single time period are all greater than or equal to the capacitance threshold, the clothing processing device is controlled to send a prompt message to the user terminal, wherein the prompt message is used to prompt the user to adjust the position of the clothing to be processed in the barrel.

[0110] Furthermore, the prompt message may be a voice message or a text message, and until feedback from the user is received, the clothing processing device is controlled to stop sending the prompt message.

[0111] S302: If there is a capacitance value greater than the capacitance threshold value among the capacitance values ​​in each time period, control the clothing processing device to perform a shaking operation on the clothing to be processed.

[0112] In this step, when it is determined that the clothing processing device has hit the barrel, and there is a capacitance value greater than the capacitance threshold in the capacitance values ​​in each time period, it is determined that the degree of entanglement of the clothes in the barrel of the clothing processing device is small, and the clothing processing device can be directly controlled to shake out the clothes to be processed.

[0113] In a possible implementation, after the shaking operation of the clothing processing devices is completed, the clothing processing devices may be controlled to run at a lower speed for a period of time, thereby further redistributing the clothing processing devices, thereby making the distribution of the clothing processing devices more even.

[0114] Furthermore, too long a dehydration time will affect the moisture content of the clothes to be processed, thereby affecting the wearing experience of the user. Therefore, when it is determined that the clothes to be processed need to be dehydrated and re-dehydrated, the remaining time of the dehydration program is obtained, and the clothes processing device is controlled to continue dehydrating the clothes to be processed according to the remaining time.

[0115] For example, the total duration of the dehydration program is 50 minutes. After 30 minutes of operation, it is determined that a barrel collision occurs, and the capacitance value in each time period is greater than the capacitance threshold, then the clothing treatment device is controlled to perform a shaking operation on the clothes to be processed. After the shaking operation is completed, the remaining time is obtained as 50-30=20 minutes, and the clothing treatment device is controlled to continue dehydrating for 20 minutes.

[0116] The present application provides a barrel collision judgment method, which selects the corresponding barrel collision processing method according to the size of the capacitance value, and continues dehydration according to the remaining dehydration time after the barrel collision processing. Through the above method, the barrel collision is processed in a timely manner, and the excessive dehydration is avoided to affect the user's wearing experience.

[0119] The judgment module 402 is used to determine whether the laundry processing device collides with the drum according to the relationship between the capacitance value and the capacitance threshold, wherein the capacitance threshold is a capacitance value obtained in advance when the outer drum of the laundry processing device collides with the housing;

[0120] The control module 403 is used to control the clothing processing device to perform a barrel collision processing operation if yes.

[0122] If the capacitance values ​​in a single time period are all greater than or equal to the capacitance threshold, it is determined that the clothing processing device has collided with the barrel;

[0123] If the capacitance value in each time period is less than the capacitance threshold, it is determined that the clothing processing device does not collide with the barrel;
