Description

Technical Field

[0001] This invention relates to the field of clothing treatment technology, specifically providing a method for judging and controlling water overflow in clothing care equipment, as well as the clothing care equipment itself. Background Technology

[0002] Garment care equipment, also known as garment care cabinets or smart garment care machines, is a modern household appliance designed to maintain, wrinkle-free, sterilize, deodorize, and dry clothes using advanced technology, thereby extending their lifespan and keeping them in optimal condition. During the drying process, air is heated by a heater and becomes hot air. As it passes through the clothes, it absorbs moisture from the clothes, turning into cool, humid air. This cool, humid air then passes through a condenser, where the moisture is released as condensate, which is stored in a water tank.

[0003] In some existing garment care devices, the water storage box is connected to an external water inlet pipe. However, if the water inlet valve on the water inlet pipe malfunctions, water will be continuously supplied to the water storage box, causing it to overflow and spill onto the ground, which is not conducive to hygiene and cleaning. Currently, there is no method to determine whether the water inlet valve is malfunctioning.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing clothing care equipment cannot determine whether the water inlet valve is malfunctioning, resulting in water overflow in the water storage box.

[0006] In a first aspect, the present invention provides a method for determining water overflow prevention in a garment care device, the garment care device including a main water tank and a water inlet pipe, the two ends of the water inlet pipe being connected to a water source and the main water tank respectively, and a water inlet valve being provided on the water inlet pipe, the determination method including:

[0007] S100: Determine whether the water level in the main water tank has reached the first upper limit water level;

[0008] S200: If the judgment result is "yes", drain the water from the main water box;

[0009] S300: Obtain the current water level in the main water tank at intervals T1, and record it as the first water level;

[0010] S400: Compare the first water level with the first preset water level;

[0011] S500: If the first water level is greater than or equal to the first preset water level, then the water inlet valve is determined to be faulty.

[0012] In the preferred embodiment of the above-mentioned judgment method, the garment care device further includes a wastewater box. The top of the main water box has an overflow outlet, which is connected to the wastewater box. Water in the wastewater box can be transported to the main water box, and water in the main water box can flow into the wastewater box through the overflow outlet. The wastewater box is configured to collect condensate generated during the operation of the garment care device. Step S100 specifically includes:

[0013] S110: Detect whether the water level in the wastewater box has reached the second upper limit water level;

[0014] S120: If the detection result is "yes", then drain the water in the wastewater box into the main water box for time T2.

[0015] S130: Obtain the current water level in the wastewater box and record it as the second water level;

[0016] S140: Calculate the water level difference between the second upper limit water level and the second water level;

[0017] S150: Determine whether the water level in the main water box has reached the first upper limit water level based on the water level difference.

[0018] In the preferred embodiment of the above judgment method, step S150 specifically includes:

[0019] Compare the water level difference with the preset water level difference:

[0020] If the water level difference is less than the preset water level difference, then it is determined that the water level in the main water tank has reached the first upper limit water level;

[0021] If the water level difference is not less than the preset water level difference, then it is determined that the water level in the main water box has not reached the first upper limit water level.

[0022] In a preferred embodiment of the above-mentioned judgment method, the judgment method further includes:

[0023] S600: If the first water level is lower than the first preset water level, then all the water in the wastewater box is drained into the main water box;

[0024] S700: Drain the water from the main water tank;

[0025] S800: After time interval T3, obtain the current water level in the wastewater box and record it as the third water level;

[0026] S900: Compare the third water level with the second preset water level;

[0027] S1000: If the third water level is greater than or equal to the second preset water level, then the inlet valve is determined to be faulty.

[0028] In a preferred embodiment of the above-mentioned judgment method, the judgment method further includes:

[0029] S1100: If the third water level is lower than the second preset water level, it is determined that the inlet valve has not malfunctioned.

[0030] In the preferred embodiment of the above-mentioned judgment method, the first preset water level is the first upper limit water level, and T1 is the time required for the inlet valve to fill the main water box from the empty state to the first upper limit water level at the maximum flow rate.

[0031] In the preferred embodiment of the above-mentioned judgment method, the second preset water level is the second upper limit water level.

[0032] T3 = T1 + △T;

[0033] Wherein, △T is the time required for the water in the main water box to fill the wastewater box from an empty state to the second upper limit water level when the water inlet valve is operating at maximum flow rate.

[0034] In a preferred embodiment of the above-mentioned judgment method, the judgment method further includes:

[0035] If the first water level is lower than the first preset water level, it is determined that the inlet valve is not malfunctioning.

[0036] In a second aspect, the present invention also provides a control method for a garment care device, the control method further comprising:

[0037] The above-described method is used to determine whether the inlet valve is malfunctioning.

[0038] If the water inlet valve is determined to be faulty, the garment care device shall issue an alarm and / or continuously drain the main water tank.

[0039] In a third aspect, the present invention also provides a garment care device, including a controller configured to perform the aforementioned judgment method, or

[0040] The controller is configured to execute the control method described above.

[0041] Those skilled in the art will understand that the technical solution of the present invention provides a method for determining water overflow prevention in a garment care device. The garment care device includes a main water tank and a water inlet pipe. The two ends of the water inlet pipe are connected to a water source and the main water tank, respectively. A water inlet valve is installed on the water inlet pipe. The control method includes: S100: determining whether the water level in the main water tank has reached a first upper limit water level; S200: if the determination result is "yes", draining the water from the main water tank; S300: acquiring the current water level in the main water tank at intervals T1, and recording it as the first water level; S400: comparing the first water level with a first preset water level; S500: if the first water level is greater than or equal to the first preset water level, determining that the water inlet valve has malfunctioned. By adopting the above technical solution, the present invention can accurately determine whether the water inlet valve has malfunctioned. Specifically, if the water level in the main water tank is detected to have reached or exceeded the first upper limit water level, the water in the main water tank should be immediately drained to prevent water overflow or equipment damage, ensuring that the water level in the main water tank drops rapidly to a safe range. After draining the main water tank, wait for a period of time (T1 time) to allow the system to stabilize, and then re-detect the water level in the main water tank (first water level). Compare the obtained first water level with a preset safe or normal water level (first preset water level). If the comparison result shows that the first water level is greater than or equal to the first preset water level, it means that after draining the main water tank and waiting for T1 time, the water level in the main water tank is still abnormally high. This situation is caused by the inlet valve failing to close properly or by leakage. Therefore, it can be determined that the inlet valve has malfunctioned.

[0042] Furthermore, the garment care device of the present invention also includes a wastewater box, the top of the main water box has an overflow outlet, the overflow outlet is connected to the wastewater box, water in the wastewater box can be transported to the main water box, and water in the main water box can flow into the wastewater box through the overflow outlet. The wastewater box is configured to collect condensate generated during the operation of the garment care device. Step S100 specifically includes: S110: detecting whether the water level in the wastewater box has reached the second upper limit water level; S120: if the detection result is "yes", draining water from the wastewater box into the main water box for time T2; S130: obtaining the current water level in the wastewater box and recording it as the second water level; S140: calculating the water level difference between the second upper limit water level and the second water level; S150: determining whether the water level in the main water box has reached the first upper limit water level based on the water level difference. By using this method, the water level difference in the wastewater box can be used to indirectly determine whether the water level in the main water box has reached the first upper limit. This not only improves the accuracy of determining whether the water level in the main water box has reached the first upper limit, but also allows the condensate in the wastewater box to be drained into the main water box, avoiding the risk of the wastewater box being overfilled.

[0051] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with a clothes dryer, the overflow prevention judgment method, control method, and clothes care device provided by the present invention are equally applicable to other products that need to solve the problem of not being able to determine whether the inlet valve has malfunctioned.

[0052] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] As mentioned in the background section, existing garment care devices cannot determine whether the inlet valve is malfunctioning, leading to water overflow in the storage tank. This invention provides a method for preventing water overflow in garment care devices, a control method, and the garment care device itself. The aim is to effectively solve the problem of garment care devices being unable to determine whether the inlet valve is malfunctioning, resulting in water overflow in the storage tank, by detecting whether the water level in the main water tank has reached a preset level after the main water tank has been drained and left to stand for a period of time.

[0054] First refer to Figure 1 ,in, Figure 1 This is a schematic diagram of the structure of the garment care device of the present invention.

[0055] like Figure 1As shown, the present invention provides a garment care device, which includes a main water box 1, a water inlet pipe 2, and a wastewater box 3. The two ends of the water inlet pipe 2 are connected to a water source and the main water box 1, respectively. A water inlet valve 21 is provided on the water inlet pipe 2. The top of the main water box 1 has an overflow port 11, which is connected to the wastewater box 3. Water in the wastewater box 3 can be transported to the main water box 1, and water in the main water box 1 can flow to the wastewater box 3 through the overflow port 11. The wastewater box 3 is configured to collect condensate generated during the operation of the garment care device.

[0056] By connecting the water inlet pipe 2 to the water source and the water inlet valve 21 installed on the main water tank 1, when the water level in the main water tank 1 drops to a certain level, the water inlet valve 21 can be opened automatically or manually to replenish water from the water source into the main water tank 1, ensuring a stable supply of water required during clothing care. This avoids the inconvenience of frequent manual water addition and improves the ease of use of the equipment.

[0057] Furthermore, garment care equipment generates condensate during operation, such as during steam ironing and drying. This invention configures the wastewater box 3 to collect this condensate, preventing environmental pollution and equipment damage caused by indiscriminate dripping. Simultaneously, because the condensate is relatively clean, the water in the wastewater box 3 can be transferred to the main water box 1 for reuse as supplementary water, thereby further improving water resource utilization efficiency.

[0058] It should be noted that the garment care device of the present invention also includes a first water pump 4, a second water pump 5, and a drain pipe 6. The inlet end of the first water pump 4 is connected to the bottom of the wastewater box 3, and the outlet end of the first water pump 4 is connected to the main water box 1. Thus, by activating the first water pump 4, water in the wastewater box 3 can be transported to the main water box 1. The inlet end of the second water pump 5 is connected to the bottom of the main water box 1, and the outlet end of the second water pump 5 is connected to the drain pipe 6. Thus, by activating the second water pump 5, water in the main water box 1 can be drained.

[0059] In addition, such as Figure 2 As shown, the present invention also provides a method for judging the water overflow prevention of clothing care equipment, the method comprising:

[0060] S100: Determine whether the water level in the main water tank 1 has reached the first upper limit water level;

[0061] S200: If the judgment result is "yes", drain the water in the main water box 1;

[0062] S300: Obtain the current water level in the main water tank 1 at intervals T1, and record it as the first water level;

[0063] S400: Compare the first water level with the first preset water level;

[0064] S500: If the first water level is greater than or equal to the first preset water level, the inlet valve 21 is determined to be faulty.

[0065] During normal operation, garment care equipment requires continuous replenishment of water to the main water tank 1 for washing, rinsing, or steam care operations. However, if the water level in the main water tank 1 is too high, it may damage the equipment or cause overflow. Therefore, an upper limit water level needs to be set for monitoring. When the water level reaches or exceeds this first upper limit water level, the water in the main water tank 1 is drained to prevent overflow or damage to the equipment. For example, in this invention, when the water level reaches or exceeds the first upper limit water level, a second drain pump is activated to ensure that the water level in the main water tank 1 is quickly reduced to a safe range.

[0066] After an interval T1, the current water level in the main water tank 1, i.e., the first water level, is obtained. This first water level is compared with a first preset water level. If the comparison shows that the first water level is greater than or equal to the first preset water level, it means that after emptying the main water tank 1 and waiting for T1, water has entered the main water tank 1, causing an abnormally high water level. This indicates that the problem is caused by the inlet valve 21 failing to close properly or by a leak. Therefore, the control method of this invention effectively determines the working status of the inlet valve 21 by real-time monitoring and comparison of the water level in the main water tank 1, thereby ensuring the safety and normal operation of the garment care equipment.

[0067] It should be noted that the first preset water level in this invention is set according to the design and operating requirements of the equipment, representing the reasonable water level range that the main water box 1 should reach after being emptied, assuming no malfunction of the inlet valve 21. Therefore, in other embodiments, the specific location or size of the first preset water level can be set and adjusted according to the actual situation, and this invention does not specifically limit the specific location or size of the first preset water level.

[0068] It should be noted that the present invention includes a water level monitoring device (not shown in the figure) installed in the main water tank 1, thereby facilitating accurate acquisition of the water level in the main water tank. Exemplarily, the water level monitoring device can be a float-type water level gauge, a pressure-type water level sensor, etc., and the present invention does not specifically limit the water level monitoring device installed in the main water tank 1.

[0069] Preferably, such as Figure 3 As shown, if the first water level is lower than the first preset water level, it is determined that the inlet valve 21 is not faulty.

[0070] Preferably, step S100 specifically includes:

[0071] S110: Check whether the water level in wastewater box 3 has reached the second upper limit water level;

[0072] S120: If the test result is "yes", drain the water in wastewater box 3 into main water box 1 for time T2.

[0073] S130: Obtain the current water level in wastewater box 3 and record it as the second water level;

[0074] S140: Calculate the water level difference between the second upper limit water level and the second water level;

[0075] S150: Determine whether the water level in the main water box 1 has reached the first upper limit water level based on the water level difference.

[0076] First, the system checks whether the water level in wastewater box 3 has reached the preset second upper limit level. If the water level in wastewater box 3 reaches the second upper limit level, the system initiates a drainage process, sending the water in wastewater box 3 into the main water box 1 via the first water pump 4. This process lasts for time T2. The purpose of this is to use the water in wastewater box 3 to replenish the main water box 1, while simultaneously lowering the water level in wastewater box 3 to prevent overflow. After the drainage process is completed, the system checks the water level in wastewater box 3 again and records this level as the second water level. This water level reflects the remaining water volume in wastewater box 3 after the drainage operation. By calculating the difference between the second upper limit level and the second water level, the system can determine how much water was discharged from wastewater box 3 during the drainage process. Finally, the system uses the water level difference in wastewater box 3 to indirectly determine whether the water level in the main water box 1 has reached the first upper limit level.

[0077] It should be noted that the aforementioned second upper limit water level is set to prevent the wastewater box 3 from becoming too full. If the water level in the wastewater box 3 is too high, water will overflow, causing environmental pollution and affecting the normal operation of the equipment. Furthermore, in other embodiments, the second upper limit water level can be set according to the design and operating requirements of the equipment. The present invention does not specifically limit the specific value of the second upper limit water level.

[0078] It should be further noted that the present invention includes a water level monitoring device (not shown in the figure) installed in the wastewater box 3, thereby facilitating and accurately obtaining the water level in the wastewater box. Exemplarily, the water level monitoring device can be a float-type water level gauge, a pressure-type water level sensor, etc., and the present invention does not specifically limit the water level monitoring device installed in the wastewater box 3.

[0079] Preferably, step S150 specifically includes:

[0080] Compare the water level difference with the preset water level difference:

[0081] If the water level difference is less than the preset water level difference, it is determined that the water level in the main water box 1 has reached the first upper limit water level;

[0082] If the water level difference is not less than the preset water level difference, it is determined that the water level in the main water box 1 has not reached the first upper limit water level.

[0083] The water level difference (i.e., the difference between the second upper limit water level and the second water level) that decreases during the drainage process of wastewater box 3 is compared with a preset water level difference threshold. If the water level difference is less than the preset water level difference, it indicates that the main water box 1 has already approached or reached the first upper limit water level before the wastewater box 3 drains. Therefore, it can be determined that the water level in the main water box 1 has reached or exceeded the first upper limit water level. If the water level difference is not less than the preset water level difference, it indicates that the main water box 1 has enough space to accommodate the water discharged from the wastewater box 3. Therefore, it can be determined that the water level in the main water box 1 has not reached the first upper limit water level.

[0084] It should be noted that if the main water box 1 has sufficient space, then when the water in the wastewater box 3 reaches the second upper limit level each time, and with the power of the first water pump 4 being constant, the water discharged from the wastewater box 3 to the main water box 1 within time T2 will be basically consistent and completely contained by the main water box 1. Therefore, within time T2, the decrease in water level difference in the wastewater box 3 will be greater than or equal to the preset water level difference, thus proving that the water level in the main water box 1 has not reached the first upper limit level. If the space in the main water box 1 is insufficient, then when the water in the wastewater box 3 reaches the second upper limit level, and with the power of the first water pump 4 being constant, within time T2, the water discharged from the wastewater box 3 to the main water box 1 will have filled the main water box 1, and some water will flow back to the wastewater box 3 through the overflow port 11 on the main water box 1. Therefore, after time T2, the decrease in water level difference in the wastewater box 3 will be less than the preset water level difference, thus proving that the water level in the main water box 1 has reached the first upper limit level.

[0085] It should be further noted that the preset water level difference in this invention is the water level at which the wastewater box 3 drops after the first water pump 4 starts, assuming a constant power of the first water pump 4. Of course, in other embodiments, the preset water level difference may be set according to actual conditions, and this invention does not impose specific limitations on it here.

[0086] Preferably, such as Figure 3 As shown, the determination method of the present invention further includes:

[0087] S600: If the first water level is lower than the first preset water level, all the water in the wastewater box 3 will be drained into the main water box 1;

[0088] S700: Drain the water from the main water tank 1;

[0089] S800: After time interval T3, obtain the current water level in wastewater box 3 and record it as the third water level;

[0090] S900: Compare the third water level with the second preset water level;

[0091] S1000: If the third water level is greater than or equal to the second preset water level, the inlet valve 21 is determined to be faulty; if the third water level is less than the second preset water level, the inlet valve 21 is determined not to be faulty.

[0092] To verify the accuracy of steps S100 to S500 in determining whether the inlet valve 21 has malfunctioned, when the first water level is lower than the first preset water level, this invention drains all the water in the wastewater box 3 into the main water box 1, and then empties the water in the main water box 1, thus leaving both the main water box 1 and the drain box empty. The system then needs to wait for a period of time (T3 time) to allow the system to stabilize and re-detect the water level in the wastewater box 3. The newly acquired third water level is compared with the preset second water level. If the comparison result shows that the third water level is greater than or equal to the second preset water level, this means that after draining the water from the wastewater box 3 into the main water box 1 and then emptying the main water box 1, the water level in the wastewater box 3 is abnormally high after T3 time. Therefore, it is determined that the inlet valve 21 failed to close correctly at some previous point in time or had a leak, causing water to fill the main water box 1 and flow into the wastewater box 3 through the overflow port 11, resulting in the water level (third water level) in the wastewater box 3 being greater than or equal to the second preset water level. Therefore, it can be determined that the inlet valve 21 has malfunctioned; conversely, it can be determined that the inlet valve 21 has not malfunctioned.

[0093] It should be noted that the second preset water level of the present invention is set according to factors such as the operating requirements of the equipment and the capacity of the wastewater box 3, representing the reasonable water level range that the wastewater box 3 should reach after being emptied under the condition that there is no malfunction of the inlet valve 21. In other embodiments, the second preset water level can be set according to the design and operating requirements of the equipment, and the present invention does not specifically limit the specific value of the second preset water level.

[0094] Preferably, the first preset water level is the first upper limit water level, and T1 is the time required for the inlet valve 21 to fill the main water box 1 from the empty state to the first upper limit water level according to the maximum flow rate.

[0095] In this invention, in step S400, the first preset water level value used for comparison with the first water level of the main water tank 1 is set as the first upper limit water level. The first upper limit water level is the maximum water level that the main water tank 1 can safely hold; exceeding this water level may cause water overflow or damage to the equipment. Therefore, setting the first preset water level as the first upper limit water level ensures that measures are taken promptly when the water level in the main water tank 1 is detected to be too high, preventing potential safety problems.

[0096] T1 represents the time required for the inlet valve 21 to fill the main water box 1 from an empty state to the first upper limit water level at its maximum flow rate. It reflects the working efficiency of the inlet valve 21 at its maximum flow rate and the filling speed of the main water box 1. In step S300, the system needs to wait for T1 time to obtain the current water level (i.e., the first water level) of the main water box 1 after emptying. This time interval is set to ensure that the inlet valve 21 has sufficient time to fill the main water box 1 at its maximum flow rate, thereby accurately reflecting the working status of the inlet valve 21 and the water level of the main water box 1. This provides the system with a more accurate and reliable basis for judgment, helping to promptly detect and handle malfunctions of the inlet valve 21, ensuring the normal operation and safety of the garment care equipment.

[0097] Preferably, the second preset water level is the second upper limit water level, and T3 = T1 + ΔT;

[0098] Wherein, △T is the time required for the water in the main water box 1 to fill the wastewater box 3 from the empty state to the second upper limit water level when the water inlet valve 21 is at its maximum flow rate.

[0099] The second preset water level is the second upper limit water level, meaning that during the judgment process, the second preset water level value compared with the water level in wastewater tank 3 is set as the second upper limit water level. The second upper limit water level is the maximum amount of wastewater that wastewater tank 3 can safely hold; exceeding this water level may cause wastewater overflow or damage to the wastewater treatment system. Setting the second preset water level as the second upper limit water level helps ensure that timely measures can be taken when the water level in wastewater tank 3 is too high, preventing potential problems from occurring.

[0100] T3 = T1 + ΔT. In this formula, as mentioned earlier, T1 is the time required for the inlet valve 21 to fill the main water box 1 from an empty state to the first upper limit water level at maximum flow rate. This is the basis for evaluating the performance of the inlet valve 21 and the filling speed of the main water box 1. After time T1, if the water level in the main water box 1 exceeds the first upper limit water level, water will flow into the wastewater box 3 through the overflow port 11. ΔT is the time required for water to flow from the main water box 1 into the wastewater box 3 through the overflow port 11 until the wastewater box 3 reaches the second upper limit water level. It reflects the filling speed of the wastewater box 3 and the efficiency of the overflow system.

[0101] By defining time T3 and a second preset water level (i.e., the second upper limit water level), the system can monitor and evaluate the operating status of inlet valve 21, main water box 1, overflow outlet 11, and wastewater box 3 over a longer time frame. If the water level in wastewater box 3 is greater than or equal to the second upper limit water level at time T3, it can be determined that inlet valve 21 has malfunctioned.

[0102] Furthermore, the present invention also provides a control method for a garment care device, the control method further comprising:

[0103] Use the above method to determine whether the inlet valve 21 is malfunctioning;

[0104] If a malfunction is detected in the inlet valve 21, the garment care equipment will issue an alarm and / or continuously drain the main water tank 1.

[0105] For example, the present invention can issue clear fault alarms to users through the display screen, sound prompts, or mobile APP of the garment care device. This helps users understand the problem in a timely manner and take appropriate measures. In addition, in order to prevent the water level from being too high due to the failure of the inlet valve 21, the system will also control the drain valve of the main water box 1 to open, so that the water in the main water box 1 is continuously discharged. This helps to protect the equipment from damage such as flooding and reduces potential safety hazards.

[0106] Furthermore, the present invention also provides a garment care device, including a controller 7, which is configured to perform the above-described judgment method or the controller 7 is configured to perform the above-described control method.
