Description

Technical Field

[0001] This invention relates to the treatment of textiles, and in particular to a control method for a garment treatment device and the garment treatment device itself. Background Technology

[0002] An existing garment processing device includes a controller, a water inlet assembly, a detergent dissolving chamber, and a washing tub. The water inlet assembly includes a first water inlet pipe for supplying water to the washing tub and a second water inlet pipe for supplying water to the detergent dissolving chamber. The detergent dissolving chamber stores the detergent solution. An extractor is installed on the first water inlet pipe, and the extractor's extraction port is connected to the detergent dissolving chamber. During daily use, the extractor's extraction port is prone to blockage, leading to a decrease in the extractor's extraction ratio. On the one hand, the actual volume of detergent solution extracted by the extractor decreases, failing to meet washing requirements and resulting in reduced washing effectiveness. On the other hand, the controller may not be able to detect the blockage in time and will continue to supply water to the detergent dissolving chamber according to the normal water inlet procedure, causing the water level in the detergent dissolving chamber to rise, eventually even overflowing, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a control method for a garment processing device that can promptly detect blockages in the extraction interface of the extractor and perform unblocking operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a control method for a garment processing device, the garment processing device comprising a controller, a water inlet assembly, a detergent dissolving chamber, and a washing tub, the water inlet assembly comprising a first water inlet pipe for supplying water to the washing tub and a second water inlet pipe for supplying water to the detergent dissolving chamber, the detergent dissolving chamber for storing detergent solution, an extractor provided on the first water inlet pipe, the extractor's extraction interface being connected to the detergent dissolving chamber, and the control method comprising the following:

[0005] After the controller receives a first threshold signal indicating that the liquid level in the detergent dissolving chamber has reached a predetermined height, the garment processing equipment performs a clearing operation on the extraction interface of the extractor.

[0006] Furthermore, a first switching valve is installed on the first inlet pipe. The first switching valve is located downstream of the extractor and is electrically connected to the controller. The unblocking work performed by the clothing processing equipment includes the following:

[0007] The controller closes the first switch valve and controls the water inlet pipe to enter the first water inlet pipe, allowing the water in the first water inlet pipe to backflush into the detergent dissolving chamber and clear the extraction port of the extractor.

[0008] Furthermore, the first water inlet pipe includes a first section located downstream of the extractor, the height of which is higher than the extraction port and detergent dissolving chamber of the extractor. The unblocking work performed by the laundry treatment equipment includes the following:

[0009] The controller shuts off the first water inlet pipe, allowing the water in the first section to backflush into the detergent dissolving chamber, thus clearing the extraction port of the extractor.

[0010] Furthermore, the first threshold signal includes a first liquid level signal and a second liquid level signal. After the controller receives the first liquid level signal, the garment processing device performs a first unblocking operation on the extraction interface of the extractor. After the controller receives the second liquid level signal, the garment processing device performs a second unblocking operation on the extraction interface of the extractor.

[0011] Furthermore, the first water inlet pipe includes a first part located downstream of the extractor. The height of the first part is higher than the extraction port and detergent dissolving chamber of the extractor. The liquid level corresponding to the first liquid level signal is lower than the liquid level corresponding to the second liquid level signal. The laundry treatment equipment performs the first unblocking operation, including the following:

[0012] The controller closes the first water inlet valve and opens the first water inlet pipe, allowing the water in the first part to backflush into the detergent dissolving chamber and clear the extraction port of the extractor.

[0013] And / or,

[0014] A first switching valve is installed on the first inlet pipe. The first switching valve is located downstream of the extractor and is electrically connected to the controller. The second unblocking operation performed by the clothing processing equipment includes the following:

[0015] The controller controls the first switch valve to close and then controls the first switch valve to open, allowing the water in the first water inlet pipe to backflush into the detergent dissolving chamber, thus clearing the extraction port of the extractor.

[0016] Furthermore, the bottom of the detergent dissolving chamber is provided with a drain pipe that communicates with the outside. A second switch valve is provided on the drain pipe. The second switch valve is electrically connected to the controller. The controller controls the second switch valve to open and discharge the liquid from the detergent dissolving chamber according to a second threshold signal that the liquid level in the detergent dissolving chamber reaches a predetermined height.

[0017] The present invention also provides a garment processing device, including a controller, a water inlet assembly, a detergent dissolving chamber, and a washing tub. The water inlet assembly includes a first water inlet pipe for supplying water to the washing tub and a second water inlet pipe for supplying water to the detergent dissolving chamber. The detergent dissolving chamber is used to store detergent solution. An extractor is provided on the first water inlet pipe. The extractor's extraction port is connected to the detergent dissolving chamber. The detergent dissolving chamber is provided with a liquid level detector. The liquid level detector is electrically connected to the controller. The controller starts the unblocking operation of the extractor's extraction port according to the trigger signal of the liquid level detector.

[0018] Furthermore, the first water inlet pipe includes a first part located downstream of the extractor. The height of the first part is higher than the height of the detergent dissolving chamber and the extraction interface of the extractor. The controller closes the first water inlet pipe according to the trigger signal of the liquid level detector, and uses the water backflow of the first part to achieve the unblocking work; and / or, the first water inlet pipe is provided with a first switching valve located downstream of the extractor. The controller closes the first switching valve and opens the first water inlet pipe according to the trigger signal of the liquid level detector, and uses the water inlet of the first water inlet pipe to achieve the unblocking work.

[0019] Furthermore, the liquid level detector includes a first detector and a second detector. The first detector generates a first liquid level signal, and the second detector generates a second liquid level signal. The controller performs a first type of unblocking operation based on the first liquid level signal and a second type of unblocking operation based on the second liquid level signal. Alternatively, the liquid level detector is a liquid level detector that continuously detects the liquid level. The liquid level detector generates a first liquid level signal when the liquid level in the detergent dissolving chamber reaches a first liquid level and generates a second liquid level signal when it reaches a second liquid level. The controller performs a first type of unblocking operation based on the first liquid level signal and a second type of unblocking operation based on the second liquid level signal.

[0020] Furthermore, the bottom of the detergent dissolving chamber is provided with a drain pipe that communicates with the outside, and a second switch valve is provided on the drain pipe. The second switch valve is electrically connected to the controller.

[0021] By adopting the above technical solution, the present invention has the following advantages: Using the liquid level in the detergent dissolving chamber as the criterion for determining blockage is simple, easy to control, and correspondingly lower in cost. Once the liquid level in the detergent dissolving chamber reaches a predetermined height and generates a first threshold signal, it indicates that the flow rate of water entering the detergent dissolving chamber is much greater than the flow rate of liquid being drawn out by the extractor, meaning the flow rate at the extractor's extraction port has significantly decreased. The controller can determine that the extractor's extraction port is blocked, thus instructing the garment processing equipment to clear the blockage at the extraction port. Since the liquid level in the detergent dissolving chamber can be obtained in real time, clearing the extraction port can be performed at any time, ensuring the long-term reliability of the garment processing equipment. Furthermore, after the controller receives the first threshold signal, the water intake of the detergent dissolving chamber stops, and the clearing operation of the extraction port is switched on. This effectively prevents liquid overflow when the extraction port of the detergent dissolving chamber is blocked, ensuring a good user experience. Attached Figure Description

[0031] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0032] Example 1:

[0033] This invention provides a control method for a garment processing device, the garment processing device including a controller, a water inlet assembly, a detergent dissolving chamber 100, and a washing tub 2, such as... Figure 1 As shown, the water inlet assembly includes a first water inlet pipe 11 for supplying water to the washing tub 2 and a second water inlet pipe 12 for supplying water to the detergent dissolving chamber 100. The detergent dissolving chamber 100 is used to store detergent solution. An extractor 3 is provided on the first water inlet pipe 11, and the extraction port 300 of the extractor 3 is connected to the detergent dissolving chamber 100. The control method includes the following:

[0034] After the controller receives a first threshold signal that the liquid level in the detergent dissolving chamber 100 has reached a predetermined height, the garment processing equipment performs a clearing operation on the extraction interface 300 of the extractor 3.

[0035] This invention uses the liquid level in the detergent dissolving chamber 100 as a criterion for determining blockage. This method is simple, easy to control, and correspondingly lower in cost. Once the liquid level in the detergent dissolving chamber 100 reaches a predetermined height and generates a first threshold signal, it indicates that the flow rate of water entering the detergent dissolving chamber 100 is much greater than the flow rate of liquid being drawn out by the extractor 3. This means the flow rate at the extractor 3's extraction port 300 has significantly decreased. The controller can then determine that the extractor 3's extraction port 300 is blocked, prompting the garment processing equipment to perform unblocking operations on the extraction port 300. Since the liquid level in the detergent dissolving chamber 100 can be obtained in real time, unblocking operations on the extraction port 300 can be performed at any time, ensuring the long-term reliability of the garment processing equipment. In addition, after the controller receives the first threshold signal, the water inlet operation of the detergent dissolving chamber 100 will stop, and the pumping port 300 will be cleared instead. This effectively prevents liquid from overflowing when the detergent dissolving chamber 100 is blocked at the pumping port 300, ensuring a good user experience. The pump 3 can be a venturi tube.

[0036] To facilitate the unblocking of the extraction interface 300, in one embodiment, a first switching valve 13 is provided on the first water inlet pipe 11. The first switching valve 13 is located downstream of the extractor 3 and is electrically connected to the controller, allowing the controller to control the opening and closing of the first switching valve 13. The unblocking operation performed by the clothing processing equipment includes the following:

[0037] The controller closes the first switch valve 13 and controls the first water inlet pipe 11 to allow water to flow in, causing the water in the first water inlet pipe 11 to backflush into the detergent dissolving chamber 100, thus clearing the extraction port 300 of the extractor 3. For specific water flow details, please refer to... Figure 2 Since the water entering through the first inlet pipe 11 is under certain pressure, the backflushing effect is relatively good and can handle more severe blockages, such as those caused by clumped laundry detergent.

[0038] In some cases, the blockage may not be severe. To save water resources, in another embodiment, the first inlet pipe 11 can be designed to include a first portion 111 located downstream of the extractor 3. The height of the first portion 111 is higher than the height of the extraction port 300 of the extractor 3 and the detergent dissolving chamber 100. The unblocking work performed by the laundry handling equipment includes the following:

[0039] The controller shuts off the first water inlet pipe 11, allowing water in the first section 111 to backflush into the detergent dissolving chamber 100, thus clearing the extraction port 300 of the extractor 3. For specific water flow details, please refer to... Figure 3The water in the first part 111 is flushed back by gravity. The amount of water in the first part 111 is limited, and the backflow is weaker than that of the water entering the first inlet pipe 11, which can accommodate minor blockages.

[0040] To prevent liquid overflow from the detergent dissolving chamber 100 during the unclogging process, a drain pipe 16 communicating with the outside can be provided at the bottom of the detergent dissolving chamber 100. A second switching valve 17 is installed on the drain pipe 16, and the second switching valve 17 is electrically connected to a controller. The controller controls the second switching valve 17 to open and discharge the liquid from the detergent dissolving chamber 100 based on a second threshold signal indicating that the liquid level in the detergent dissolving chamber 100 has reached a predetermined height. The liquid level at which the second threshold signal is generated will be higher than the liquid level at which the first threshold signal is generated.

[0041] To control the water intake or shut-off of the first inlet pipe 11, a first inlet valve 14 can be installed on the first inlet pipe 11. The first inlet valve 14 is electrically connected to the controller and is controlled by the controller. Similarly, to control the water intake or shut-off of the second inlet pipe 12, a second inlet valve 15 can be installed on the second inlet pipe 12. The second inlet valve 15 is electrically connected to the controller and is controlled by the controller. Alternatively, a three-way valve can be installed to control the water intake of both the first inlet pipe 11 and the second inlet pipe 12.

[0042] Example 2:

[0043] Understandably, if only one type of unblocking operation is used, it will either require a large amount of water, potentially leading to some waste, or the unblocking effect will be insufficient, failing to resolve the blockage. Therefore, in another embodiment, both minor and severe blockages can be addressed. For example, the first threshold signal can be designed to include a first liquid level signal and a second liquid level signal. Upon receiving the first liquid level signal, the garment processing device performs a first type of unblocking operation targeting the extraction interface 300 of the extractor 3. Upon receiving the second liquid level signal, the garment processing device performs a second type of unblocking operation targeting the extraction interface 300 of the extractor 3. This more targeted approach to different levels of blockage can save water resources.

[0044] Specifically, for minor blockages, the first water inlet pipe 11 can be designed to include a first part 111 located downstream of the extractor 3. The height of the first part 111 is higher than the height of the extraction port 300 and the detergent dissolving chamber 100 of the extractor 3. The liquid level corresponding to the first liquid level signal is lower than the liquid level corresponding to the second liquid level signal. The first unblocking operation performed by the laundry processing equipment includes the following:

[0045] The controller controls the first water inlet valve to close and controls the first water inlet pipe 11 to open, allowing the water in the first part 111 to backflush into the detergent dissolving chamber 100, thus clearing the extraction port 300 of the extractor 3.

[0046] For severe blockages, a first switching valve 13 can be installed on the first inlet pipe 11. The first switching valve 13 is located downstream of the extractor 3 and is electrically connected to the controller. The second unblocking operation performed by the clothing processing equipment includes the following:

[0047] The controller controls the first switch valve 13 to close and then controls the first switch valve 13 to open, allowing the water in the first water inlet pipe 11 to backflush into the detergent dissolving chamber 100, thus clearing the extraction port 300 of the extractor 3.

[0048] Other content not described in this embodiment can be found in Embodiment 1.

[0049] Example 3:

[0050] The present invention also provides a garment processing device, including a controller, a water inlet assembly, a detergent dissolving chamber 100, and a washing tub 2, such as... Figure 1 As shown, the water inlet assembly includes a first water inlet pipe 11 for supplying water to the washing tub 2 and a second water inlet pipe 12 for supplying water to the detergent dissolving chamber 100. The detergent dissolving chamber 100 is used to store detergent solution. An extractor 3 is provided on the first water inlet pipe 11, and the extraction port 300 of the extractor 3 is connected to the detergent dissolving chamber 100. The detergent dissolving chamber 100 is provided with a level detector 101, which is electrically connected to a controller. The controller starts the unblocking operation of the extraction port 300 of the extractor 3 according to the trigger signal of the level detector 101. Alternatively, a level detector 101 capable of continuously detecting the real-time water level can be selected.

[0051] In one embodiment, to achieve unblocking, the first water inlet pipe 11 can be designed to include a first portion 111 located downstream of the extractor 3. The height of the first portion 111 is higher than the height of the detergent dissolving chamber 100 and the extraction port 300 of the extractor 3. The controller closes the first water inlet pipe 11 based on the trigger signal from the level detector 101, utilizing the backflow of water in the first portion 111 to achieve unblocking. The water in the first portion 111 is backflushed by gravity. The amount of water in the first portion 111 is limited and weaker than the backflow of water entering the first water inlet pipe 11, which can accommodate minor blockages. In another embodiment, the first water inlet pipe 11 is equipped with a first switching valve 13 located downstream of the extractor 3. The controller closes the first switching valve 13 and opens the first water inlet pipe 11 based on the trigger signal from the level detector 101, utilizing the water entering the first water inlet pipe 11 to achieve unblocking. Since the water entering through the first inlet pipe 11 is under pressure, the backflushing effect is relatively good, which can handle more severe blockages, such as those caused by clumped laundry detergent. Understandably, these two embodiments can be implemented simultaneously, employing different unblocking methods for different types of blockages.

[0052] The liquid level detector 101 can be a distributed detector designed for specific liquid levels. The number of liquid level detectors 101 is determined by the number of liquid levels to be detected. For example, the liquid level detector 101 may include a first detector and a second detector. The first detector generates a first liquid level signal, and the second detector generates a second liquid level signal. The controller performs a first type of unblocking operation based on the first liquid level signal and a second type of unblocking operation based on the second liquid level signal.

[0053] In another embodiment, the level detector 101 can be selected as a continuous level detector 101. The level detector 101 generates a first level signal when the liquid level in the detergent dissolving chamber 100 reaches a first level and a second level signal when it reaches a second level. The controller performs a first unblocking operation based on the first level signal and a second unblocking operation based on the second level signal. The first unblocking operation can be the aforementioned unblocking method for minor blockages, and the second unblocking operation can be the aforementioned unblocking method for severe blockages. Of course, other feasible unblocking methods can also be used.

[0054] To prevent liquid from overflowing from the detergent dissolving chamber 100 during the unclogging process, a drain pipe 16 communicating with the outside can be provided at the bottom of the detergent dissolving chamber 100. A second switch valve 17 is provided on the drain pipe 16, and the second switch valve 17 is electrically connected to the controller.

[0055] Other content not described in this embodiment can be referred to in the above embodiments.

[0056] In addition to the preferred embodiments described above, there are other embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
