Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular, relates to a clothing processing equipment and a control method thereof. Background Art

[0002] Washing machines are commonly used clothing processing equipment. During operation, due to the high-speed rotation of the drum, if the clothes are unevenly placed, the entire machine is prone to shifting, making the entire machine prone to collision with surrounding objects, making loud noises, and prone to malfunction.

[0003] Because the inner drum rotates at a high speed, uneven distribution of laundry inside the drum can cause the laundry machine to vibrate. High vibrations can easily cause the machine to move, increasing noise levels and potentially causing damage, posing a safety hazard.

[0004] The Chinese patent application number 202111256025.4 discloses a clothing processing device. When the device body is placed normally on the supporting surface, the detection component is opposite to the first height matching surface. At this time, the device body does not move, the whole machine operation circuit is in the on state, and the device body can operate normally; when the device body moves due to excessive vibration or other reasons, the detection component is staggered with the first height matching surface, and the detection component is opposite to the second height matching surface. The detection component can detect the height change of the matching surface with it. At this time, the device body moves, the whole machine operation circuit is in the off state, and the device body stops running.

[0005] This patent sets up a detection component to detect whether the device body has shifted by changing the height of the mating surface with it. The detection accuracy is low and a height difference construction structure needs to be designed separately, which is costly. At the same time, the device body can only be installed in a fixed position to detect whether it has shifted.

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

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a clothing processing device to avoid the safety hazards caused by displacement of the clothing processing device due to vibration and the like, and at the same time provide a control method for the clothing processing device.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A clothes processing device, characterized by comprising:

[0010] An acquisition module is used to obtain the current humidity value of the area covered by the bottom foot of the clothing treatment device when it is working;

[0011] A storage module for storing set humidity values ​​of the footing coverage area under different environments;

[0012] A comparison module compares the current humidity value of the footing coverage area obtained with the stored set humidity value under the current environment;

[0013] A judgment module determines whether the foot has shifted based on the comparison result;

[0014] The control module controls the clothes processing device to correct the operating parameters of the inner tub when it is determined that the bottom foot is displaced.

[0015] Furthermore, the acquisition module is configured as a humidity sensor installed on the footing, and the humidity sensor detects the humidity value between the footing and the ground in real time.

[0016] Furthermore, the acquisition module acquires the current humidity value of the footing coverage area at least twice at a set time interval, and obtains the set humidity value by calculating the average value.

[0017] Furthermore, if it is detected that clothes are put into the inner tub, the acquisition module first acquires the set humidity value of the bottom foot covering area before the inner tub rotates, and then acquires the current humidity value of the bottom foot covering area after the inner tub rotates.

[0018] Furthermore, it also includes an alarm prompt module, which is connected to the judgment module. The alarm prompt module sends an alarm message to the user according to the judgment result of the judgment module.

[0019] The basic concept of another technical solution of the present invention is:

[0020] A control method for a clothes processing device is applied to the clothes processing device as described above, comprising:

[0021] Get the current humidity value of the area covered by the bottom of the clothing treatment device when it is working;

[0022] Compare the obtained current humidity value of the footing coverage area with the stored set humidity value under the current environment;

[0023] Determine whether the bottom foot is displaced, and if so, control the clothes processing device to correct the operating parameters of the inner drum.

[0024] Furthermore, the set temperature value is set to an average of humidity values ​​of the footing coverage area obtained multiple times;

[0025] Alternatively, the set humidity value is a fixed value preset according to different environments.

[0026] Furthermore, the different environments include at least different placement positions, and the operating parameters include at least rotation speed and / or washing time.

[0027] Furthermore, if the difference between the current humidity value of the area covered by the bottom foot and the set humidity value is lower than the set value, the clothes processing device is controlled to reduce the speed of the inner drum or shorten the washing time;

[0028] If the difference between the current humidity value of the area covered by the bottom foot and the set humidity value is greater than or equal to the set value, the clothes processing device is controlled to stop working.

[0029] Furthermore, the difference between the humidity value of the area covered by the foot and the set humidity value is in direct proportion to the displacement distance of the clothing processing device.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] (1) In the present invention, the occurrence of abnormal noise, displacement and collision of the clothing processing equipment can be avoided in advance, and the problems of vibration and displacement caused by high-speed operation of the clothing processing equipment can be avoided, which may cause damage to the clothing processing equipment and user complaints.

[0032] (2) In the present invention, it is determined whether the clothing processing device has shifted, and the clothing processing device is controlled to execute the corresponding washing program or washing parameters, so that the clothing processing device reduces the rotation speed or stops working and issues an alarm, thereby preventing the clothing processing device from being damaged by collision or endangering the personal safety of the user.

[0033] (3) In the present invention, the current humidity value of the area covered by the bottom foot is mainly detected in real time by the humidity sensor, and compared with the stored set humidity value to determine whether the clothing processing device has shifted. The detection accuracy is high, the error is small, and the response speed is fast.

DETAILED DESCRIPTION

[0044] 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.

Therefore, they cannot be understood as limiting the present invention.

[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] Example 1

[0048] like Figure 1 As shown, the present invention provides a clothes processing device, comprising:

[0049] Acquisition module 1, used to obtain the current humidity value of the area covered by the bottom foot of the clothing treatment device when it is working;

[0050] Storage module 2, used to store the set humidity values ​​of the footing coverage area under different environments;

[0051] Comparison module 3 compares the current humidity value of the footing coverage area obtained with the stored set humidity value under the current environment;

[0052] The judgment module 4 judges whether the foot has shifted according to the comparison result;

[0053] The control module 5 controls the clothes processing device to correct the operating parameters of the inner tub when it is determined that the bottom foot is displaced.

[0054] Preferably, this embodiment is illustrated by taking a pulsator washing machine 100 as an example. When the pulsator washing machine 100 is working, the inner drum rotates at high speed to complete washing. The pulsator washing machine 100 includes a box body and feet arranged at the bottom of the box body. When the inner drum rotates at high speed, the feet in contact with the ground will shift. By judging the humidity change in the area covered by the feet, it is judged whether the pulsator washing machine 100 has shifted, and the user is reminded to take timely measures to avoid safety hazards in the pulsator washing machine 100.

[0055] The pulsator washing machine 100 can be placed in the bathroom or balcony, or in different locations in the bathroom. The set humidity values ​​of these placement points are different. It is worth noting that when the pulsator washing machine 100 is not moved, the ambient humidity outside the base has a negligible effect on the humidity of the area covered by the base.

[0056] Furthermore, the acquisition module 1 is configured as a humidity sensor installed on the base. By configuring the humidity sensor, the humidity value of the area covered by the base can be accurately obtained. The humidity sensor detects the humidity value between the base and the ground in real time, and can accurately capture slight changes in humidity and convert them into electrical signals.

[0057] It should be noted that when the pulsator washing machine 100 is placed in a fixed area, the humidity value of the area covered by the base of the ground remains unchanged. If the pulsator washing machine 100 is shifted, the base will also shift accordingly. At this time, the coverage area of ​​the base and the ground will change, that is, the humidity value will change. By judging that the humidity value has changed, it can be known that the pulsator washing machine 100 has shifted.

[0058] It is worth noting that the pulsator washing machine 100 can be placed in a bathroom or balcony, or in different locations within the bathroom or balcony, or in different seasons or regions. Different regions, including the north and south, may result in different set humidity values ​​at these locations. To obtain an accurate set humidity value, the acquisition module 1 acquires the current humidity value of the foot-covered area at least twice at a set interval, depending on the different placement locations, and calculates the average value to obtain the set humidity value.

[0059] Furthermore, when the pulsator washing machine 100 is placed in a certain area, the set humidity value needs to be determined based on the current humidity value of the area covered by the base. By obtaining the humidity value of the area covered by the base multiple times, the average value of the humidity values ​​obtained multiple times is calculated, and the average value is used as the set humidity value.

[0060] It should be noted that the humidity value is set based on the average of multiple humidity values ​​of the foot covering area, so that a more accurate judgment standard is provided for subsequent changes in the humidity value of the foot covering area to indicate that the washing machine has shifted.

[0061] Furthermore, if it is detected that there are clothes in the inner drum, the acquisition module 1 first obtains the set humidity value of the bottom foot covering area before the inner drum rotates, and then obtains the current humidity value of the bottom foot covering area after the inner drum rotates. It is necessary to first determine the set humidity value and then obtain the humidity value of the bottom foot covering area in real time when the washing machine is working. The comparison module 3 will only work when the washing machine is working.

[0062] Specifically, a weight sensor is provided at the bottom of the inner tub. When the user puts clothes into the inner tub, the inner tub detects the addition of clothes through the weight sensor provided at the bottom. The acquisition module 1 first obtains the set humidity value of the bottom foot covering area before the inner tub rotates, and then obtains the current humidity value of the bottom foot covering area after the inner tub rotates after the inner tub starts to rotate and wash clothes.

[0063] Alternatively, the clothing processing device detects that a washing program has been input, indicating that the user is ready to wash clothes. The acquisition module 1 first obtains the set humidity value of the bottom foot covering area before the inner drum rotates, and then obtains the current humidity value of the bottom foot covering area after the inner drum rotates after the inner drum starts to rotate to wash clothes.

[0064] It should be noted that the acquisition module 1 needs to first obtain the humidity value of the base coverage area within the interval time. By setting the interval time, it is ensured that the obtained humidity value is more stable.

[0065] Example 2

[0066] This embodiment is a further explanation of the first embodiment.

[0067] like Figure 2 As shown, the clothing processing device provided in this embodiment also includes an alarm prompt module 6, which is connected to the judgment module 4. The alarm prompt module 6 sends an alarm message to the user based on the judgment result of the judgment module 4. By setting the alarm prompt module 6, the user can be reminded in time to avoid the washing machine hitting the wall in advance and avoid safety hazards.

[0068] In this embodiment, the alarm module 6 receives the signal from the judgment module 4 and issues a prompt or alarm to remind the user. The alarm and prompt can be distinguished by different colors of display lights, directly displayed through text, or realized by buzzer sounding, voice broadcast, etc.

[0069] Specifically, if the judgment module 4 determines that the pulsator washing machine 100 is displaced, the alarm prompt module 6 sends an alarm prompt signal according to the judgment result of the judgment module 4 to remind the user that the pulsator washing machine 100 may cause a safety accident due to displacement.

[0070] The rest is the same as in Example 1.

[0071] Example 3

[0072] This embodiment is a further explanation of Embodiments 1 and 2.

[0073] like Figure 3 As shown, the clothing processing device provided in this embodiment also includes a communication module 7, which connects the user's smart terminal and the control module 5. The communication module 7 sends prompt information to the user's smart terminal. The communication module 7 sends the washing program or washing parameters selected by the user to the control module 5. The control module 5 controls the clothing processing device to execute the corresponding washing program or washing parameters.

[0074] In this embodiment, the user intelligent terminal is illustrated by a mobile phone. The communication module 7 sends the judgment result of the judgment module 4 to the user's mobile phone. The user can see the displacement of the corresponding pulsator washing machine 100 on his or her mobile phone, and the user can monitor the status of the pulsator washing machine 100 at any time.

[0075] In this embodiment, the user can control the washing program or washing parameters of the pulsator washing machine 100 through a mobile phone. The user can select the washing program and its washing parameters of the pulsator washing machine 100 on the mobile phone. After the user clicks, the communication module 7 can send the washing program and its washing parameters selected by the user to the control module 5. The control module 5 controls the pulsator washing machine 100 to execute the washing program and its washing parameters selected by the user for washing.

[0076] In this embodiment, the user receives the judgment result of the judgment module 4 through the mobile phone. If the mobile phone receives a signal that the pulsator washing machine 100 has shifted, the user adjusts the washing program or washing parameters of the pulsator washing machine 100 through the mobile phone, such as reducing the speed of the inner drum, shortening the washing time or stopping the work, and sends the user's command to the control module 5 through the user's mobile phone. The control module 5 controls the pulsator washing machine 100 to reduce the speed of the inner drum, shorten the washing time or stop the work.

[0077] The rest is the same as in Examples 1 and 2.

[0078] Example 4

[0079] like Figure 4 As shown, the present invention provides a control method for a clothes processing device, which is applied to the clothes processing devices in the first to third embodiments, including:

[0080] Get the current humidity value of the area covered by the bottom of the clothing treatment device when it is working;

[0081] Compare the obtained current humidity value of the footing coverage area with the stored set humidity value;

[0082] Determine whether the foot is displaced, and if so, control the clothes processing device to execute a corresponding washing program and / or washing parameters.

[0083] In this embodiment, the set temperature value is set to the average value of humidity values ​​of the foot covering area obtained multiple times, or the set humidity value is a fixed value preset according to different environments.

[0084] Furthermore, different environments include at least different seasons and different placement locations. The pulsator washing machine 100 can be placed in the bathroom or balcony, or in different locations of the bathroom or balcony, or in the above locations in different seasons. In short, the set humidity values ​​of these placement points are different. The set temperature value is set to a pre-set fixed value to avoid detection errors. The user can also make adjustments later according to actual needs to meet user needs.

[0085] In this embodiment, due to variations in frequency of use, the difference between the humidity level in the area covered by the foot of the washing machine during operation and the set humidity level is not constant. When the difference is small, for example, below the set value, the speed of the washing machine drum can be reduced to prevent the washing machine from crashing. When the difference is large, the pulsator washing machine 100 is stopped to avoid safety accidents.

[0086] It should be noted that the set value in this embodiment is a preset value and can also be adjusted by the user or maintenance personnel based on experience or the contents of the user manual.

[0087] In this embodiment, the inner drum operating parameters of the pulsator washing machine 100 at least include the rotation speed and / or the washing time.

[0088] Specifically, if the difference between the humidity value of the area covered by the bottom foot and the set humidity value is lower than the set value, the rotation speed of the drum of the pulsator washing machine 100 can be reduced to prevent the washing machine from colliding or shorten the washing time of the pulsator washing machine 100.

[0089] In this embodiment, the difference between the humidity value of the area covered by the foot and the set humidity value is in direct proportion to the displacement distance of the clothing processing device.

[0090] Specifically, after the footing is moved, the humidity value of the area covered by the footing will change because it is no longer the previous coverage area. The greater the difference between the humidity value of the area covered by the footing and the set humidity value, the greater the distance the footing has moved.

[0091] Specifically, when the difference between the humidity value of the area covered by the base and the set humidity value is lower than the set value, it indicates that the base has shifted but not by a large distance. It can also be understood that the displacement distance of the pulsator washing machine 100 is still within a safe range. At this time, the inner barrel of the pulsator washing machine 100 is controlled to reduce the speed or shorten the washing time to avoid safety accidents.

[0092] Specifically, when the difference between the humidity value of the area covered by the foot and the set humidity value is not lower than the set value, it indicates that the displacement distance of the foot has exceeded the normal displacement distance. At this time, the pulsator washing machine 100 is controlled to stop working to avoid safety accidents.

[0093] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, they are not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
