Description

Technical Field

[0001] This disclosure relates to the field of clothing processing equipment technology, and in particular to a method, apparatus and clothing processing equipment for detecting water ingress in clothing processing equipment. Background Technology

[0002] Existing laundry handling equipment (such as smart washing machines) will alarm when the water pressure is low or the tap is left running. Machines with flow sensors directly detect the water flow and alarm if the flow is abnormal. Machines without flow sensors determine whether water is entering the machine by observing the trend of water level frequency changes. During the operation of a smart washing machine, especially in the rinsing stage, water that has already entered the washing machine drum may be continuously discharged due to the siphon effect. In a short period of time, it can be detected that the water level frequency has changed or that a certain flow has been detected by the flow sensor, but this does not accurately reflect the water intake status of the washing machine. However, because the water is flowing out, washing cannot be performed, causing an alarm. In related technologies, there is no good way to deal with the alarm caused by the continuous water intake due to the siphon effect. Summary of the Invention

[0003] This disclosure provides a method, apparatus, and garment processing equipment for detecting water ingress into a garment processing device.

[0004] The technical solution disclosed herein is as follows:

[0005] According to a first aspect of the present disclosure, a method for detecting water inlet in a garment processing device is provided.

[0006] According to a second aspect of the present disclosure, a water inlet detection device for a garment processing equipment is provided. The device includes: a water level detection module for detecting the water level in the garment processing drum during the water inlet phase of the garment processing equipment; a first control module for controlling the inlet valve to close and controlling the drain pump to operate in a set mode in response to the water level meeting the abnormal conditions of the drain pump, the set mode being used to eliminate siphon balance, the abnormal conditions of the drain pump including at least the water level being lower than a target water level after a first preset water inlet time; and a second control module for controlling the inlet valve to open after the drain pump has finished operating in the set mode.

[0009] According to a fifth aspect of the present disclosure, a computer program product is provided, comprising a computer program, characterized in that, when the computer program is executed by a processor, it implements the water ingress detection method for a clothing processing device as provided in the first aspect of the present disclosure.

[0010] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0011] This disclosure discloses a water inlet detection method for a clothing processing device. During the water inlet stage of the clothing processing device, the water level inside the clothing processing drum is detected. In response to the water level meeting the abnormal conditions of the drain pump, the inlet valve is closed, and the drain pump is controlled to operate in a set mode. This set mode is used to eliminate siphon balance. The abnormal conditions of the drain pump include at least a water level lower than a target water level after a first preset water inlet time.

[0021] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0022] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0023] Figure 1 This is a schematic flowchart of a water ingress detection method for a garment processing device provided in an embodiment of this disclosure.

[0024] like Figure 1 As shown, the water ingress detection method for this garment processing equipment includes the following steps:

[0025] S101, during the water intake stage of the garment processing equipment, the water level inside the garment processing drum is detected.

[0026] It should be noted that this disclosure does not limit the type of clothing processing equipment; optionally, the clothing processing equipment can be a washing machine.

[0027] It should be noted that this disclosure does not limit the specific method for detecting the water level in the garment processing drum during the water inlet stage of the garment processing equipment; the appropriate method can be selected based on the actual situation.

[0028] Optionally, the water level in the laundry treatment drum can be detected by a water level sensor.

[0029] It should be noted that during the water intake stage of the garment processing equipment, a water level sensor can be used to detect the speed and magnitude of the rise or fall of the water level, so as to detect the water level in the garment processing drum during the water intake stage of the garment processing equipment.

[0030] Optionally, the water level in the garment processing drum can be detected using a flow sensor.

[0031] It should be noted that during the water intake stage of the clothing processing equipment, the water flow rate and flow volume can be monitored by a flow sensor to determine the water intake volume. The water level can be calculated by combining the water intake volume with the capacity of the clothing processing drum, so as to detect the water level in the clothing processing drum during the water intake stage of the clothing processing equipment.

[0032] S102, in response to the water level meeting the abnormal conditions of the drainage pump, controls the inlet valve to close and controls the drainage pump to operate in a set mode. The set mode is used to eliminate siphon balance. The abnormal conditions of the drainage pump include at least the water level being lower than the target water level after a first preset time of water intake.

[0033] It should be noted that this disclosure does not limit the process for determining whether the water level meets the abnormal conditions of the drainage pump, and the appropriate method can be selected according to the actual situation.

[0034] Optionally, if the water level is lower than the target water level after the first preset time of water intake based on the water level, and the water level in the clothes processing drum continues to drop, it is determined that the water level meets the abnormal conditions of the drainage pump.

[0035] Optionally, it is determined that the water level in the clothing treatment drum continues to drop, and the rate of water level drop is obtained. In response to the rate of water level drop being greater than or equal to a set rate, it is determined that the water level meets the abnormal conditions of the drain pump. In response to the rate of water level drop being less than the set rate and the water level being lower than a preset water level, it is determined that the water level meets the abnormal conditions of the drain pump. The preset water level is lower than the target water level.

[0036] Optionally, in response to the water level being lower than a preset water level, it is determined that the water level meets the abnormal conditions of the drainage pump, wherein the preset water level is lower than the target water level.

[0037] Optionally, if the water level is lower than the target water level after the second preset time for water intake is determined based on the water level, it is determined that the water level meets the abnormal conditions of the drainage pump.

[0038] It should be noted that if the laundry processing equipment continues to fill with water in response to the water level meeting the abnormal conditions of the drain pump, the siphon effect will cause a simultaneous inflow and outflow phenomenon, resulting in the inability to reach the target water level. Eventually, an alarm will be triggered to remind the user of the abnormal water inflow. In this case, the inlet valve can be closed and the drain pump can be controlled to operate in the set mode to eliminate the siphon imbalance.

[0039] For example, if several machines share the same drainage system or if water enters the system while the drainage process is being switched, a siphon effect may occur during drainage.

[0040] Siphon balance refers to the phenomenon in which the water flow stops when the water levels in two pipes reach the same level. Siphon is a physical phenomenon caused by the pressure difference generated by the height difference of the liquid in the pipe, which causes the liquid to flow from the higher to the lower level. Even if the water source at the higher level is cut off, the liquid will continue to flow until the liquid levels on both sides reach the same level.

[0041] In this embodiment of the disclosure, the drainage pump can be controlled to operate alternately in forward and reverse directions to eliminate siphon imbalance.

[0042] S103 controls the inlet valve to open after the drainage pump finishes running in the set mode.

[0043] In this embodiment of the present disclosure, after the drain pump finishes operating in the set mode, the water inlet valve is opened and the clothes handling equipment continues to supply water. After the water supply resumes, the water level in the clothes handling drum is continuously monitored. In response to the water level in the clothes handling drum reaching the target water level within a third set time period, the water supply stage ends and the washing stage begins. In response to the water level in the clothes handling drum not reaching the target water level within the third set time period, an abnormal water supply alarm is triggered.

[0044] This disclosure discloses a water inlet detection method for a clothing processing device. By detecting the water level in the clothing processing drum during the water inlet stage, and responding to a situation where the water level meets the abnormal conditions of the drain pump, the inlet valve is closed, and the drain pump is controlled to operate in a set mode. This set mode is used to eliminate siphon balance. The abnormal conditions of the drain pump include at least a water level lower than a target water level after a first preset water inlet time. After the drain pump finishes operating in the set mode, the inlet valve is opened. Therefore, this disclosure eliminates siphon balance by controlling the drain pump to operate in a set mode when the water level meets the abnormal conditions of the drain pump, solving the problem of simultaneous inlet and outlet due to siphon during water inlet, eliminating false alarms caused by simultaneous inlet and outlet due to siphon, and improving the user experience.

[0045] Figure 2 This is a schematic flowchart of a water ingress detection method for a garment processing device according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 2The specific process of water ingress detection for clothing processing equipment is explained, including the following steps:

[0046] S201, during the water intake stage of the garment processing equipment, the water level inside the garment processing drum is detected.

[0047] S202, based on the water level, after the first preset time of water intake, the water level is lower than the target water level, and the water level in the clothes processing drum continues to drop, thus determining that the water level meets the abnormal conditions of the drainage pump.

[0048] S203, determine that the water level in the garment processing drum is continuously decreasing, and obtain the rate of water level decrease.

[0049] For example, when the water level in the laundry drum continues to drop, the amount of water level change and the corresponding time interval can be obtained, and the rate of water level drop v can be determined based on the amount of water level change and the corresponding time interval.

[0050] S204, in response to the water level drop rate being greater than or equal to the set rate, determine that the water level meets the abnormal conditions of the drainage pump.

[0051] The set speed can be understood as the threshold for the rate at which the water level drops, used to determine whether the rate of water level drop is normal.

[0052] In this embodiment of the disclosure, after obtaining the water level drop rate v, it is determined whether the water level drop rate is greater than or equal to a set rate v. th The response is that the rate of water level drop is greater than or equal to the set rate, i.e., v ≥ v th If so, it is determined that the water level meets the abnormal conditions of the drainage pump.

[0053] S205, in response to the water level drop rate being less than the set rate and the water level being lower than the preset water level, it is determined that the water level meets the abnormal conditions of the drainage pump, wherein the preset water level is lower than the target water level.

[0054] In this embodiment of the disclosure, after obtaining the water level drop rate v, it is determined whether the water level drop rate is less than a set rate v. th This is in response to the water level dropping rate being less than the set rate, i.e., v < v th If the water level is lower than the preset water level, that is, when the water level is lower than the inner cylinder position, then the water level is determined to meet the abnormal conditions of the drainage pump.

[0055] S206, in response to the water level meeting the abnormal conditions of the drainage pump, controls the inlet valve to close and controls the drainage pump to operate in a set mode, the set mode being used to eliminate siphon balance.

[0056] In this embodiment of the disclosure, the drainage pump is controlled to alternate between forward and reverse rotation a set number of times.

[0057] In this disclosure, there is no limitation on the number of times that can be set. For example, the number of times can be set to 2 times, or the number of times can be set to 3 times.

[0058] For example, if the drainage pump rotates forward for 5 seconds, rotates in reverse for 5 seconds, and has a flow rate of 15 L / min, and the set number of cycles is 2, meaning the drainage pump alternates between forward and reverse rotation twice, then the total operating time of the drainage pump is 20 seconds. Since the flow rate of the drainage pump is 15 L / min when rotating forward, the flow rate when rotating in reverse is often less than 15 L / min. Therefore, controlling the drainage pump to alternate between forward and reverse rotation twice will discharge a total of about 3 L of water to agitate the continuous water flow of the siphon and eliminate the siphon balance.

[0059] S207 controls the opening of the inlet valve after the drainage pump finishes operating in the set mode.

[0060] In this embodiment of the present disclosure, after the drain pump finishes running in the set mode and the water inlet valve is opened, the water level in the clothes processing drum is monitored after the water inlet resumes. If the water level in the clothes processing drum reaches the target water level within a third set time period, the water inlet stage ends and the washing stage begins. If the water level in the clothes processing drum does not reach the target water level within the third set time period, a drain pump abnormality alarm is triggered.

[0061] The target water level can be understood as the water level that meets normal washing needs.

[0062] For example, if the water level in the laundry tub does not reach the target water level within the third set time period, it is determined that the water level meets the abnormal conditions of the drain pump. A continuous or intermittent alarm sound can be emitted through the internal buzzer or speaker, and the corresponding color will be lit by the indicator light of the laundry equipment to trigger an alarm for abnormal drain pump operation.

[0063] This disclosure discloses a water inlet detection method for a clothing processing device. During the water inlet stage, the water level in the clothing processing drum is detected. Based on the water level, if the water level is lower than a target level after a first preset inlet time and the water level in the clothing processing drum continues to drop, it is determined that the water level meets the abnormal conditions for the drain pump. The method also determines the rate of water level drop and, in response to the rate of drop being greater than or equal to a set rate, confirms that the water level meets the abnormal conditions for the drain pump. If the rate of drop is less than the set rate and the water level is lower than a preset water level, it is also confirmed that the water level meets the abnormal conditions for the drain pump. When the preset water level is lower than the target water level, the inlet valve is closed, and the drain pump is controlled to operate in a set mode to eliminate siphon balance. After the drain pump finishes operating in the set mode, the inlet valve is opened. Thus, this disclosure determines that the water level meets the abnormal conditions for the drain pump. By controlling the drain pump to alternate between forward and reverse rotation a set number of times, siphon balance can be eliminated, preventing false alarms caused by simultaneous inlet and outlet due to siphoning, improving the user experience, and increasing the processing efficiency of the clothing processing device.

[0064] Figure 3 This is a schematic flowchart of a water ingress detection method for a garment processing device according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 3 The specific process of water ingress detection for clothing processing equipment is explained, including the following steps:

[0065] S301, during the water intake stage of the garment processing equipment, the water level inside the garment processing drum is detected.

[0066] S302, in response to the water level being lower than the preset water level, determine that the water level meets the abnormal conditions of the drainage pump, wherein the preset water level is lower than the target water level.

[0067] S303, in response to the water level meeting the abnormal conditions of the drainage pump, controls the inlet valve to close and controls the drainage pump to operate in a set mode, which is used to eliminate siphon balance.

[0068] In this embodiment of the disclosure, the drainage pump is controlled to alternate between forward and reverse rotation a set number of times.

[0069] In this disclosure, there is no limitation on the number of times that can be set. For example, the number of times can be set to 2 times, or the number of times can be set to 3 times.

[0070] For example, if the drainage pump rotates forward for 5 seconds, rotates in reverse for 5 seconds, and has a flow rate of 15 L / min, and the set number of cycles is 2, meaning the drainage pump alternates between forward and reverse rotation twice, then the total operating time of the drainage pump is 20 seconds. Since the flow rate of the drainage pump is 15 L / min when rotating forward, the flow rate when rotating in reverse is often less than 15 L / min. Therefore, controlling the drainage pump to alternate between forward and reverse rotation twice will discharge a total of about 3 L of water to agitate the continuous water flow of the siphon and eliminate the siphon balance.

[0071] S304 controls the inlet valve to open after the drainage pump finishes operating in the set mode.

[0072] In this embodiment of the present disclosure, after the drain pump finishes running in the set mode and the water inlet valve is opened, the water level in the clothes processing drum is monitored after the water inlet resumes. If the water level in the clothes processing drum reaches the target water level within a third set time period, the water inlet stage ends and the washing stage begins. If the water level in the clothes processing drum does not reach the target water level within the third set time period, a drain pump abnormality alarm is triggered.

[0073] For example, if the water level in the laundry tub does not reach the target water level within the third set time period, it is determined that the water level meets the abnormal conditions of the drain pump. A continuous or intermittent alarm sound can be emitted through the internal buzzer or speaker, and the corresponding color will be lit by the indicator light of the laundry equipment to trigger an alarm for abnormal drain pump operation.

[0074] This disclosure discloses a water inlet detection method for a clothing processing device. By detecting the water level in the clothing processing drum during the water inlet stage, and determining that the water level is below a preset level, the method determines that the water level meets the abnormal conditions for the drain pump. Specifically, if the preset water level is below a target water level, the inlet valve is closed, and the drain pump is controlled to operate in a set mode to eliminate siphon balance. After the drain pump finishes operating in the set mode, the inlet valve is opened. Thus, this disclosure eliminates siphon balance by controlling the drain pump to alternately rotate forward and reverse a set number of times when the water level is below the preset level and meets the abnormal conditions for the drain pump. This resolves false alarms caused by simultaneous inlet and outlet due to siphoning, improves the user experience, and increases the processing efficiency of the clothing processing device.

[0075] Figure 4 This is a schematic flowchart of a water ingress detection method for a garment processing device according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 4 The specific process of water ingress detection for clothing processing equipment is explained, including the following steps:

[0076] S401, during the water intake stage of the garment processing equipment, the water level inside the garment processing drum is detected.

[0077] S402, after determining the second preset time for water intake based on the water level, if the water level is lower than the target water level, it is determined that the water level meets the abnormal conditions of the drainage pump.

[0078] In this disclosure, the setting of the second set duration is not limited. For example, the second set duration can be 15 minutes, or for example, the second set duration can be 10 minutes.

[0079] For example, if the second set time is 15 minutes, and it is determined that the water level in the laundry tub has not reached the target water level within 15 minutes, it is determined that the drain pump has an inlet abnormality.

[0080] S403, in response to the water level meeting the abnormal conditions of the drainage pump, controls the inlet valve to close and controls the drainage pump to operate in a set mode, which is used to eliminate siphon balance.

[0081] In this embodiment of the disclosure, the drainage pump is controlled to alternate between forward and reverse rotation a set number of times.

[0082] In this disclosure, there is no limitation on the number of times that can be set. For example, the number of times can be set to 2 times, or the number of times can be set to 3 times.

[0083] For example, if the drainage pump rotates forward for 5 seconds, rotates in reverse for 5 seconds, and has a flow rate of 15 L / min, and the set number of cycles is 2, meaning the drainage pump alternates between forward and reverse rotation twice, then the total operating time of the drainage pump is 20 seconds. Since the flow rate of the drainage pump is 15 L / min when rotating forward, the flow rate when rotating in reverse is often less than 15 L / min. Therefore, controlling the drainage pump to alternate between forward and reverse rotation twice will discharge a total of about 3 L of water to agitate the continuous water flow of the siphon and eliminate the siphon balance.

[0084] S404 controls the opening of the inlet valve after the drain pump finishes operating in the set mode.

[0085] In this embodiment of the present disclosure, after the drain pump finishes running in the set mode and the water inlet valve is opened, the water level in the clothes processing drum is monitored after the water inlet resumes. If the water level in the clothes processing drum reaches the target water level within a third set time period, the water inlet stage ends and the washing stage begins. If the water level in the clothes processing drum does not reach the target water level within the third set time period, a drain pump abnormality alarm is triggered.

[0086] For example, if the water level in the laundry tub does not reach the target water level within the third set time period, it is determined that the water level meets the abnormal conditions of the drain pump. A continuous or intermittent alarm sound can be emitted through the internal buzzer or speaker, and the corresponding color will be lit by the indicator light of the laundry equipment to trigger an alarm for abnormal drain pump operation.

[0087] This disclosure discloses a water inlet detection method for a clothing processing device. By detecting the water level in the clothing processing drum during the water inlet stage, and determining that the water level is lower than the target water level after a second preset water inlet time, the method determines that the water level meets the abnormal conditions for the drain pump. In response to this, the method controls the inlet valve to close and controls the drain pump to operate in a set mode to eliminate siphon balance. After the drain pump finishes operating in the set mode, the method controls the inlet valve to open. Thus, this disclosure determines that the water level is lower than the target water level after a second preset water inlet time, and that the water level meets the abnormal conditions for the drain pump. By controlling the drain pump to alternate between forward and reverse rotation a set number of times, the siphon balance is eliminated, preventing false alarms caused by simultaneous inlet and outlet due to siphoning. This improves the user experience and increases the processing efficiency of the clothing processing device.

[0088] The specific process of the water ingress detection method of the clothing treatment equipment according to the present disclosure embodiment will be explained below.

[0089] For example, such as Figure 5 As shown, during the water intake stage of the laundry processing equipment, the water level in the laundry processing drum is detected. If the water level in the laundry processing drum reaches the target water level and the water intake time is less than or equal to the target water intake time, the water intake stage ends and the washing stage begins. If the water level is lower than the target water level after a first preset water intake time (the first preset time is longer than the target water intake time), it is determined that the water level meets the drain pump malfunction condition. Based on the water level, if the water level is lower than the target water level after the first preset water intake time and the water level in the laundry processing drum continues to drop, it is determined that the water level meets the drain pump malfunction condition. If the water level in the laundry processing drum continues to drop, the water level drop rate is obtained. If the water level drop rate is greater than or equal to the set rate, it is determined that the water level meets the drain pump malfunction condition. If the water level drop rate is less than the set rate and the water level is lower than the preset rate, it is determined that the water level meets the drain pump malfunction condition. The system determines whether the water level meets the drain pump malfunction criteria. Specifically, if the preset water level is lower than the target water level, and the water level is lower than the preset water level, the system confirms that the drain pump malfunction is met. If the preset water level is lower than the target water level, and the water level is lower than the target water level after a second preset water inlet time, the system determines that the drain pump malfunction is met. The system then closes the inlet valve and controls the drain pump to alternate between forward and reverse rotation a set number of times. After the set number of alternating forward and reverse rotations is completed, the inlet valve opens. After water inlet resumes, water level detection continues. If the water level in the laundry tub reaches the target water level within a third preset time, the water inlet phase ends and the washing phase begins. If the water level in the laundry tub does not reach the target water level within the third preset time, a drain pump malfunction alarm is triggered.

[0090] In summary, the water inlet detection method of the clothing processing equipment in this embodiment, after determining that the water level meets the abnormal conditions of the drain pump, controls the drain pump to alternately run forward and reverse a set number of times to eliminate siphon balance and eliminate false alarms caused by simultaneous inlet and outlet due to siphon. When the water level in the clothing processing drum reaches the target water level within a third set time period, the water inlet stage ends and the washing stage begins, improving the processing efficiency of the clothing processing equipment. If the water level in the clothing processing drum does not reach the target water level within the third set time period, an abnormal alarm for the drain pump is triggered, ensuring the safety of the clothing processing drum during operation and improving the user experience.

[0091] Figure 6 This is a block diagram illustrating a water ingress detection device for a garment processing apparatus according to an exemplary embodiment.

[0092] like Figure 6 As shown, the water inlet detection device 1000 of the garment processing equipment includes: a water level detection module 110, a first control module 120, and a second control module 130.

[0093] Water level detection module 110 is used to detect the water level in the garment processing drum during the water inlet stage of the garment processing equipment;

[0094] The first control module 120 is used to control the inlet valve to close and control the drainage pump to operate in a set mode in response to the water level meeting the abnormal conditions of the drainage pump. The set mode is used to eliminate siphon balance. The abnormal conditions of the drainage pump include at least the water level being lower than the target water level after a first preset water inlet time.

[0095] The second control module 130 is used to control the opening of the inlet valve after the drainage pump has finished operating in the set mode.

[0096] Furthermore, the first control module 120 is also used to: determine that the water level meets the abnormal conditions of the drainage pump after the water level is less than the target water level after a first preset time of water intake, and the water level in the clothes processing drum continues to drop.

[0097] Furthermore, the device 1000 is also used to: determine that the water level in the clothes processing drum is continuously decreasing, and obtain the water level decreasing rate; in response to the water level decreasing rate being greater than or equal to a set rate, determine that the water level meets the abnormal conditions of the drainage pump.

[0098] Furthermore, the device 1000 is also used to: determine that the water level meets the abnormal conditions of the drainage pump in response to the water level drop rate being less than a set rate and the water level being lower than a preset water level, wherein the preset water level is lower than the target water level.

[0099] Furthermore, the first control module 120 is also configured to: determine that the water level meets the abnormal conditions of the drainage pump in response to the water level being lower than a preset water level, wherein the preset water level is lower than the target water level.

[0100] Furthermore, the first control module 120 is also used to: determine that the water level is less than the target water level after a second preset time period of water intake based on the water level, and determine that the water level meets the abnormal conditions of the drainage pump.
