Technical Field

[0001] The present invention relates to the technical field of washing equipment, and in particular provides a control method for washing equipment and washing equipment. Background Art

[0002] With the development of technology and the continuous improvement of user needs, the functions and types of washing equipment are becoming more and more abundant, and the washing effect has also been greatly improved. At the same time, users have also put forward higher requirements for the stability and safety of washing equipment. For example, the quietness, sealing and other performance of washing equipment are the focus of users' attention.

[0003] At present, the mainstream solution is to add shock-absorbing materials and sealing materials to the washing equipment to ensure quietness and sealing.

[0004] However, during operation, existing washing equipment will inevitably encounter sealing abnormalities such as the cover not being closed tightly or accidentally popping open, which will lead to increased vibration, increased noise, and water overflow of the equipment, thereby affecting the normal operation of the equipment and even causing technical problems such as damage to the equipment.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problem, namely, when the existing washing equipment has sealing abnormalities such as the cover not being closed tightly or accidentally popping open during operation, it will cause the vibration of the equipment to intensify, the noise to increase, and the water to overflow, thereby affecting the normal operation of the equipment or even damaging the equipment.

[0007] In a first aspect, the present invention provides a control method for a washing device, wherein the washing device includes a barrel and a cover, the barrel having a take-in / take-out opening, and the cover covering the take-in / take-out opening. The control method includes: determining whether the cover is properly covered during the execution of a washing mode; selectively executing a protection mode based on the judgment result; and in the protection mode, reducing the impeller speed of the washing device and / or lowering the water level in the barrel.

[0008] In the preferred technical solution of the above control method, the specific step of "selectively executing the protection mode according to the judgment result" includes: if the cover body is closed in place, the protection mode is not executed; if the cover body is not closed in place, the protection mode is executed.

[0009] In a preferred technical solution of the above control method, in the case where "the cover is not closed in place", the control method of the present invention further comprises: sending a first prompt signal to the user.

[0010] In the preferred technical solution of the above control method, after "issuing a first prompt signal to the user", the control method of the present invention further includes: if no opening or closing movement of the cover is detected within a preset time; then stopping the operation of the pulsator.

[0011] In the preferred technical solution of the above-mentioned control method, the washing device also includes a box body and a drawer, the barrel body is located on the drawer, and the drawer is slidingly connected to the box body to drive the barrel body into the box body and close the box body. The control method also includes: judging whether the drawer is closed in place; and selectively reducing the rotation speed of the impeller based on the judgment result.

[0012] In the preferred technical solution of the above control method, the specific steps of "selectively reducing the rotation speed of the impeller according to the judgment result" include: if the drawer is closed in place, the rotation speed of the impeller is not reduced; if the drawer is not closed in place, the rotation speed of the impeller is reduced.

[0013] In a preferred technical solution of the above control method, the control method further includes: before executing the washing mode, determining whether the cover and / or the drawer are closed in place; and selectively issuing a second prompt signal based on the determination result.

[0014] In the preferred technical solution of the above control method, the specific step of "selectively issuing a second prompt signal based on the judgment result" includes: if the cover and / or the drawer are not closed in place, issuing a second prompt signal; if the cover and the drawer are closed in place, not issuing a second prompt signal.

[0015] In a second aspect, the present invention further provides a washing device, comprising a controller configured to execute the above control method.

[0016] In a preferred technical solution of the above-mentioned washing equipment, the washing equipment is configured as a shoe washing machine.

[0017] In the case of adopting the above technical solution, the washing device of the present invention includes a barrel body and a cover body, the barrel body has a take-in and put-out opening, and the cover body covers the take-in and put-out opening. The control method of the present invention includes: judging whether the cover body is fully covered during the execution of the washing mode; selectively executing the protection mode according to the judgment result; in the protection mode, reducing the impeller speed of the washing device and / or lowering the water level in the barrel body. Through such a setting, the sealing between the cover body and the barrel body can be monitored in real time during the operation of the washing device, and when the seal between the cover body and the barrel body is not tight, it can be discovered and executed in time. By reducing the speed and lowering the water level, the vibration and noise of the device are suppressed, and the water flow in the barrel body is prevented from overflowing and damaging the device, so that the device can continue to operate safely and stably, while taking into account both safety and washing efficiency, and playing an effective protective role for the device.

[0018] Furthermore, the control method of the present invention further includes: if the cover is fully closed, the protection mode is not executed; if the cover is not fully closed, the protection mode is executed. By setting the closed state of the cover as the trigger condition for the protection mode, the intervention of the protection mode is more accurate and timely.

[0019] Furthermore, in the event that the lid is not fully closed, the control method of the present invention further includes: issuing a first prompt signal to the user. This arrangement allows the user to check the lid's closing status while the protection mode is in effect, allowing the user to take timely and effective countermeasures to prevent the lid from remaining open, which could cause further damage, thereby improving the safety of the washing machine.

[0020] Furthermore, after "issuing the first prompt signal to the user," the control method of the present invention further includes: if no lid opening or closing movement is detected within a preset time, then stopping the pulsator. This configuration allows continued detection of lid reopening after the prompt signal is issued to determine whether the user has successfully received the first prompt signal and taken appropriate action. This prevents situations where the user fails to receive the prompt signal and the action is not taken for an extended period of time, thereby preventing further losses by shutting down the device. This provides multiple safety safeguards for the operation of the device and further enhances the safety and reliability of the washing machine.

[0021] Furthermore, the washing device of the present invention further includes a box body and a drawer, the barrel body is located on the drawer, and the drawer is slidably connected to the box body to drive the barrel body into the box body and close the box body. The control method of the present invention also includes: judging whether the drawer is closed in place; and selectively reducing the rotation speed of the impeller according to the judgment result. Through such a setting, on the one hand, the barrel body is installed on the box body in a pull-out form, which facilitates the combination and placement of the washing device with other washing devices, prevents mutual interference of the open positions, ensures the normal opening and closing of each device, and improves the space utilization rate in the room; on the other hand, the rotation speed of the impeller is selectively reduced according to the closing state of the drawer, and the impeller can be slowed down when the drawer is not closed in place, preventing the drawer from continuing to open due to vibration, so that vibration and noise are effectively controlled, and the stability and safety of the equipment operation are guaranteed.

[0022] Furthermore, the control method of the present invention further includes: if the drawer is fully closed, the impeller speed is not reduced; if the drawer is not fully closed, the impeller speed is reduced. This configuration, on the one hand, sets the drawer closing state as the trigger condition for reducing the impeller speed, making the control logic more reasonable and accurate; on the other hand, while ensuring the safety of the washing machine, the low speed operation can be maintained, thereby ensuring the safety and washing efficiency of the washing machine.

[0023] Furthermore, the control method of the present invention further includes: determining whether the lid and / or drawer are fully closed before executing the washing mode; and selectively issuing a second prompt signal based on the determination result. This configuration allows the lid and drawer closure status of the washing machine to be checked before the washing mode is executed, ensuring that the washing mode can be entered with the lid and drawer securely closed, further enhancing the safety and reliability of the washing machine.

[0024] Furthermore, the control method of the present invention further includes: if the lid and / or drawer are not fully closed, a second prompt signal is issued; if the lid and drawer are fully closed, the second prompt signal is not issued. With this arrangement, the second prompt signal can be issued to the user when at least one of the lid and drawer has a closure abnormality, prompting the user to check the closure status of the lid and drawer, resolve the abnormality in a timely manner, and ensure that the lid and drawer are fully closed before executing the washing mode, thereby avoiding missed detections.

[0025] In addition, the washing equipment further provided by the present invention on the basis of the above technical solution adopts the above control method, and thus has the technical effects of the above control method. Compared with the washing equipment before the improvement, the washing equipment of the present invention can promptly send a prompt signal to the user and automatically take effective measures to deal with abnormal situations when the cover is not completely closed or is accidentally opened during operation, so as to prevent the vibration and noise of the equipment from increasing and avoid water overflow, thereby ensuring the safety and stability of the washing equipment and extending the service life of the equipment.

[0026] Furthermore, the washing device of the present invention is configured as a shoe washing machine. Through such a configuration, the combination scheme of the household washing device is made more flexible and diverse, the multifunctional configuration of the washing device is realized, and the user experience and convenience are improved.

[0033] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] It should be noted that, in the description of the present invention, terms such as "inside", "outside", "up", "down", "top", and "bottom" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0035] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "installed" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] Based on the technical problem pointed out in the background art, when the existing washing equipment has sealing abnormalities such as the cover not being closed tightly or accidentally popping open during operation, it will cause the equipment to vibrate more, the noise to increase, and the water to overflow, thereby affecting the normal operation of the equipment or even damaging the equipment. To this end, the present invention provides a control method for a washing equipment, the specific steps of which include: judging whether the cover is closed in place during the execution of the washing mode; selectively executing the protection mode according to the judgment result; in the protection mode, reducing the impeller speed of the washing equipment and / or lowering the water level in the barrel, so that when the sealing of the cover is abnormal, timely and effective measures can be taken to prevent the vibration from being aggravated and the water from overflowing, thereby improving the stability and safety of the washing equipment during use and extending the service life of the equipment.

[0037] Specifically, if Figure 1 and Figure 2 As shown, the washing device of the present invention includes a barrel body 1 and a cover body 2. The barrel body 1 has a take-in and put-out opening, and the cover body 2 covers the take-in and put-out opening. The control method of the present invention includes:

[0038] S100: During the washing mode, it is determined whether the cover is properly closed.

[0039] S200: selectively executing a protection mode according to the judgment result;

[0040] In the protection mode, the impeller speed of the washing machine is reduced and / or the water level in the tub is lowered.

[0041] Exemplarily, a sealing component (usually a sealing rubber ring or rubber gasket) is provided on the cover body 2 and / or the barrel body 1. When the cover body 2 is closed in place, the sealing component can ensure the sealing between the cover body 2 and the barrel body 1, preventing the cover body 2 from shaking during the operation of the equipment and the overflow of water in the barrel body 1.

[0042] However, in actual use, abnormal situations in which the cover 2 and the barrel body 1 are not sealed tightly often occur. For example, clothes or other foreign objects are sandwiched between the cover 2 and the barrel body 1, making it impossible for the two to cover completely, or the locking structure and limiting structure of the cover 2 are aged and deformed due to long-term use, resulting in a low fit between the two, or the vibration of the motor during the operation of the equipment causes the cover 2 to be accidentally popped open, etc. These situations will all lead to abnormal sealing with a gap between the cover 2 and the barrel body 1.

[0043] The washing equipment of the present invention is provided with a detection device between the cover body 2 and the barrel body 1, and the detection device is electrically connected to the controller. By transmitting the detection signal to the controller in real time, the controller uniformly controls the motor and / or drain valve of the washing equipment, thereby executing the protection mode of the washing equipment.

[0044] Specifically, in the protection mode, the controller will realize low-speed operation of the impeller by reducing the speed of the motor, thereby reducing the vibration and noise of the equipment; and / or control the drain valve in the barrel body 1 to open, discharge part of the washing water in the barrel body 1, and lower the liquid level, thereby reducing the risk of water overflowing from the barrel body 1 under the stirring of the impeller.

[0045] It should be noted that, in actual applications, those skilled in the art can flexibly set the type and position of the detection device, such as setting a pressure sensor, a light sensor or an electromagnetic sensor along the edge of the cover body 2, which can effectively sense the position where the edge of the cover body 2 and the barrel body 1 are not tightly fitted, accurately detect the sealing abnormality between the two, and judge whether the cover body 2 is in place by detecting the fit or gap between the cover body 2 and the barrel body 1, and selectively execute the protection mode according to the judgment result, providing an accurate basis for the execution of the protection mode.

[0046] Therefore, by monitoring the covering state and sealing between the cover body 2 and the barrel body 1 in real time during the operation of the washing equipment, and being able to promptly detect and execute the protection mode when an abnormal sealing occurs between the cover body 2 and the barrel body 1, the vibration of the equipment can be suppressed by reducing the rotation speed and / or lowering the water level, the noise level can be controlled, and the water flow in the barrel body 1 can be prevented from overflowing and damaging the equipment, so that the equipment can continue to operate safely and stably, while ensuring the operating safety and washing efficiency of the equipment, and playing an effective protective role for the equipment.

[0047] Preferably, if Figure 1 and Figure 3 As shown, the specific steps of "selectively executing the protection mode based on the judgment result" include:

[0048] S210: If the cover is closed in place, the protection mode is not executed;

[0049] S220: If the cover is not closed properly, the protection mode is executed.

[0050] For example, when the cover 2 is closed in place, it indicates that the sealing between the cover 2 and the barrel body 1 is good, there is no risk of increased vibration and water overflow, and the normal operation of the washing mode can be maintained.

[0051] When the cover 2 is not closed properly, the cover 2 will shake violently as the motor runs at high speed, which will cause the noise to increase. At the same time, the cover 2 will open further during the shaking process, and the water in the barrel will overflow in large quantities under the stirring of the impeller, causing damage to the machine and the ground, or even equipment failure. Therefore, it is necessary to immediately execute the protection mode to prevent the above situation from happening.

[0052] By detecting the closing state of the cover body 2 and setting the closing state as the triggering condition of the protection mode, the intervention of the protection mode is made more accurate, ensuring that the user handles abnormal situations more promptly and avoids causing greater losses.

[0053] Preferably, if Figure 1 and Figure 3 As shown, in the case where the cover is not fully closed, the control method of the present invention further includes:

[0054] S230: Sending a first prompt signal to the user.

[0055] For example, when it is detected that the cover 2 is not closed in place, the washing device will send a first prompt signal to the user while executing the protection mode. In actual application, a voice prompt or buzzer can be played through the player, or a prompt message can be displayed through the display panel or a prompt message can be sent to the user's mobile terminal through the communication module, etc. As long as it can play the role of prompting the user, the first prompt signal can remind the user to check the closing condition of the cover 2, so that the user can take effective countermeasures in time to deal with the sealing abnormality of the cover 2, prevent the cover 2 from being in the open state for a long time and causing greater losses, thereby improving the safety of the washing device.

[0056] Preferably, if Figure 3 As shown, after "issuing a first prompt signal to the user", the control method of the present invention further includes:

[0057] S240: If no opening or closing movement of the cover is detected within a preset time, the pulsator is stopped.

[0058] Specifically, if no opening or closing movement of the cover 2 is detected after a period of time after the first prompt signal is sent to the user, it means that the user has not received the first prompt signal or is unable to handle it in time because he is out. If the device continues to run, the risk of water overflow or even damage to the device will increase.

[0059] Based on this, the control method of the present invention will directly determine that the user does not have the conditions to immediately inspect and handle the cover 2 if no reopening of the cover 2 is detected after the first prompt signal is issued for a preset time. At this time, the power will be forced to be cut off, the motor will stop rotating, and the washing device will enter standby mode to ensure the safety of the device before the user arrives.

[0060] It should be noted that the preset time can be flexibly set to any length according to actual conditions, such as one minute, two minutes or three minutes, etc. The present invention preferably sets the preset time to one minute.

[0061] This arrangement can continue to detect whether the cover body 2 has been reopened after the prompt signal is sent, so as to determine whether the user has successfully received the first prompt signal and check the abnormal state of the cover body 2, thereby preventing the situation where the user does not take any processing action for a long time due to not receiving the prompt signal, and avoiding further expansion of losses by forced shutdown, thereby building multiple safety guarantees for the operation of the equipment and further improving the safety and reliability of the washing equipment.

[0062] Preferably, the washing device of the present invention further includes a box 3 and a drawer 4, the barrel 1 is located on the drawer 4, the drawer 4 is slidably connected to the box 3 to drive the barrel 1 into the box 3 and close the box 3, and the control method of the present invention further includes:

[0063] S300: Determine whether the drawer is fully closed;

[0064] S400: Selectively reduce the rotation speed of the impeller according to the judgment result.

[0065] Illustratively, the washing device of the present invention adopts a side-pull structure, that is, the side of the box body 3 has an opening, the drawer 4 is slidably connected in the opening, and drives the drawer 4 in and out of the box body 3, the taking and placing opening of the barrel body 1 is located at the top of the barrel body 1, and the cover body 2 is set to open upward. During use, the barrel body 1 needs to be slid out of the box body 3 before the cover body 2 can be opened to complete the taking and placing of clothes. After the barrel body 1 slides into the box body 3, the opening and closing operation of the cover body 2 cannot be performed.

[0066] This structure facilitates the combination and placement of a washing machine with other washing machines. For example, when the space in the housekeeping room is limited, multiple washing machines can be stacked vertically. For example, the washing machine of the present invention is placed on the ground, and another washing machine can be stacked on top of it. Compared with the structure with an open top, the cover 2 of the washing machine of the present invention is not affected by the washing machine above, and the cover 2 can be opened and closed freely by pulling it from the side, avoiding mutual interference between the two machines when taking and putting clothes, ensuring the normal opening and closing of each machine, and improving the space utilization rate in the room.

[0067] The control method of the present invention can selectively reduce the rotation speed of the impeller according to the closing state of the drawer 4, and reduce the speed of the device when the drawer 4 is not closed, thereby preventing the drawer 4 from continuing to open due to vibration, so that the vibration and noise of the device are effectively controlled, ensuring the stability and safety of the device operation.

[0068] Preferably, the specific steps of “selectively reducing the rotation speed of the impeller according to the judgment result” include:

[0069] S410: If the drawer is fully closed, the rotation speed of the impeller is not reduced;

[0070] S420: If the drawer is not fully closed, reduce the rotation speed of the impeller.

[0071] For example, if the drawer 4 is closed in place, it can be ensured that the drawer 4 will not vibrate or shake when the motor is running, and at this time it is only necessary to maintain the normal operation of the equipment.

[0072] If drawer 4 is not closed in place, drawer 4 will vibrate violently with the rapid operation of the motor and will gradually slide outward, resulting in increased shaking and noise, and even equipment damage. At this time, it is necessary to reduce the speed of the impeller in time to control the vibration intensity and noise intensity of drawer 4 to prevent equipment damage.

[0073] By setting the closed state of drawer 4 as the trigger condition for reducing the impeller speed, the control logic is made more reasonable and accurate, and while ensuring the safety of the equipment, the equipment can continue to operate at a low speed, while ensuring the safety and washing efficiency of the washing equipment.

[0074] In addition, when the drawer 4 is not fully closed and the system reduces the rotation speed of the impeller, the present invention will also forcibly shut down the device according to actual conditions. The present invention provides two specific implementation methods for this:

[0075] In the first embodiment, a vibration sensor is installed on the washing device, which can detect the vibration amplitude of the drawer 4. When the vibration amplitude reaches a preset amplitude, the device will be forced to shut down.

[0076] In the second real-time mode, a displacement sensor is also installed on the washing device to detect the displacement of the drawer 4. When the drawer 4 slides outward to a preset distance, it will be forced to shut down.

[0077] Through the above arrangement, the washing equipment can be protected more effectively to prevent the vibration from increasing and damaging the equipment.

[0078] Preferably, the control method of the present invention further includes:

[0079] S500: Before executing the washing mode, determine whether the cover and / or drawer are closed in place;

[0080] S600: selectively sending a second prompt signal according to the judgment result.

[0081] Therefore, before the washing device executes the washing mode, the closed state of the cover 2 and the drawer 4 is first detected to ensure that the device can enter the washing mode with the cover 2 and the drawer 4 tightly closed, further improving the safety and reliability of the washing device.

[0082] Preferably, the specific steps of “selectively issuing a second prompt signal according to the judgment result” include:

[0083] S610: If the cover and / or drawer are not closed, a second prompt signal is issued;

[0084] S620: If the cover and the drawer are fully closed, no second prompt signal is issued.

[0085] For example, when at least one of the cover 2 and the drawer 4 has a closing abnormality, the system will send a second prompt signal to the user to remind the user to check the closing status of the cover 2 and the drawer 4, resolve the abnormality in time, and ensure that the cover 2 and the drawer 4 are closed in place before executing the washing mode to avoid missed detection.

[0086] Similarly, the second prompt signal can be played as a voice prompt or beep sound through the player, or a prompt message can be displayed on the control panel, or a prompt message can be sent to the user's mobile terminal through the communication module, etc., as long as it can play the role of prompting the user. Preferably, the second prompt signal has two types, which can distinguish between abnormalities in the cover body 2 and abnormalities in the drawer 4, so that the user can accurately determine whether the location of the sealing abnormality is the cover body 2 or the drawer 4, which is convenient for the user to handle it quickly.

[0087] Only when the cover 2 and the drawer 4 are fully closed, the system will not send the second prompt signal, thereby allowing the device to normally execute the washing mode.

[0088] In addition, the washing device further provided by the present invention on the basis of the above technical solution adopts the above control method, and thus has the technical effect of the above control method. Compared with the washing device before the improvement, the washing device of the present invention can promptly send a prompt signal to the user and automatically take effective measures to deal with abnormal situations when the cover body 2 is not completely closed or is accidentally opened during operation, so as to prevent the vibration and noise of the equipment from increasing and avoid water overflow, thereby ensuring the safety and stability of the washing device and extending the service life of the equipment.

[0089] Preferably, the washing device of the present invention is configured as a shoe washing machine.

[0090] For example, the shoe washing machine of the present invention can be placed on the ground, and a washing machine or dryer can be stacked on top of it, making the combination of household washing equipment more flexible and diverse, realizing the multifunctional configuration of the washing equipment, and improving the user experience and convenience.

[0091] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
