Description

Technical Field

[0001] This application relates to the field of fabric treatment equipment technology, and more specifically, to a fabric treatment device. Background Technology

[0002] With the promotion of energy conservation and environmental protection, more and more drum washing machines are adding circulating spray systems to enhance washing performance, shorten washing time, and thus achieve energy-saving effects. Existing circulating spray systems on the market include a drain pump, spray nozzles, and a circulating water circuit. Their working principle is as follows: When the drum washing machine is in the washing stage, the drain pump provides power to draw the washing water between the inner and outer drums into the circulating water circuit. The washing water then enters the spray nozzles through the circulating water circuit, causing the washing water to be sprayed onto the clothes in the inner drum, thereby achieving water circulation.

[0003] However, as the washing time of drum washing machines increases, the circulating spray system is prone to lint blockage. The current structure of the circulating spray system in drum washing machines makes it difficult for users to clean the lint, resulting in a certain risk of malfunction. Utility Model Content

[0080] Background Introduction

[0081] With the promotion of energy conservation and environmental protection, more and more drum washing machines are adding circulating spray systems to enhance washing performance, shorten washing time, and thus achieve energy-saving effects. Existing circulating spray systems on the market include a drain pump, spray nozzles, and a circulating water circuit. Their working principle is as follows: When the drum washing machine is in the washing stage, the drain pump provides power to draw the washing water between the inner and outer drums into the circulating water circuit. The washing water then enters the spray nozzles through the circulating water circuit, causing the washing water to be sprayed onto the clothes in the inner drum, thereby achieving water circulation.

[0082] However, as washing times in drum washing machines increase, the circulating spray system is prone to lint blockage. The current design of the circulating spray system in drum washing machines makes it difficult for users to clean the lint, leading to a certain risk of malfunction.

[0083] Based on this, such as Figures 1-10 As shown, a first aspect of this application provides a fabric processing apparatus, comprising:

[0084] Fabric treatment cylinder 10 and circulating spray device, the circulating spray device including:

[0085] The three-way structure 20 has a three-way cavity 201 inside and a first water inlet 202, a water outlet 203 and a second water inlet 204 communicating with the three-way cavity on its surface.

[0086] The spray pipeline includes a first inlet pipe 30 and a drain pipe 40. The first inlet pipe 30 is connected to the first inlet 202, and the drain pipe 40 is connected to the drain 203. The end of the first inlet pipe 30 away from the first inlet 202 and the end of the drain pipe 40 away from the drain 203 are both connected to the fabric treatment cylinder 10. A spray pump 50 is provided on the spray pipeline. When the spray pump 50 is turned on, the washing water in the fabric treatment cylinder 10 can enter the three-way cavity 201 through the first inlet pipe 30 and can be discharged back into the fabric treatment cylinder 10 through the drain pipe 40, so that the fabric treatment equipment can operate in a circulating spray washing mode.

[0087] A filter screen 60 is disposed in the three-way cavity 201 and divides the three-way cavity 201 into a first cavity 2011 and a second cavity 2012 connected by filter screen holes. The first cavity 2011 is connected to the first water inlet pipe 30, and the second cavity is connected to the drain pipe 40 and the second water inlet 204. The washing water entering the first cavity 2011 through the first water inlet pipe 30 can be filtered by the filter screen 60 and flow into the second cavity 2012, and discharged through the drain pipe 40 connected to the second cavity 2012.

[0088] The spray pipeline also includes a second water inlet pipe 70. One end of the second water inlet pipe 70 is connected to the second water inlet 204, and the other end is connected to the water inlet valve 80. When the water inlet valve 80 is opened, the spray pump 50 is closed, so that while the circulating spray washing stops, the cleaning water enters the second chamber 2012 through the second water inlet pipe 70 and enters the first chamber 2011 through the filter screen 60 to perform backwash cleaning on the filter screen 60.

[0089] In this embodiment, by setting a three-way structure 20 in the fabric processing equipment and connecting the three-way structure 20 to different pipelines, the fabric processing equipment can both filter the washing water through the filter screen 60 during circulating spray washing and perform backwashing self-cleaning of the filter screen 60 when it becomes clogged, thus eliminating the need for manual cleaning of the lint on the filter screen 60.

[0090] Specifically, when the fabric treatment equipment needs to operate in a circulating spray washing mode, the spray pump 50 is turned on and the inlet valve 80 is closed. At this time, the washing water in the fabric treatment drum 10 enters the three-way structure 20 through the first inlet pipe 30, and after being filtered by the filter screen 60 in the three-way structure 20, it is discharged back into the fabric treatment drum 10 through the drain pipe 40, thereby achieving the circulating spray washing effect of the fabric treatment equipment.

[0091] More specifically, when the filter screen 60 becomes clogged, the spray pump 50 is turned off to stop the circulating spray washing, and the water inlet valve 80 is opened at the same time. Since the drain pipe 40 is closed at this time, the cleaning water that enters the three-way structure 20 through the water inlet valve 80 will flow to one side of the first water inlet pipe 30, thereby achieving backwashing and cleaning of the filter screen 60, thus achieving the self-cleaning effect of the filter screen 60.

[0092] Furthermore, in some possible embodiments, the fabric treatment device further includes:

[0093] Sensor 90 is used to acquire and output parameter values ​​that characterize the degree of clogging of filter 60;

[0094] The controller is used to control the opening and closing of the spray pump 50 and the inlet valve 80 according to parameter values.

[0095] In this embodiment, by obtaining the dirt and clogging value of the filter screen 60, the opening and closing of the spray pump 50 and the water inlet valve 80 can be automatically controlled, thereby realizing the automatic detection and automatic cleaning effect of the dirt and clogging degree of the filter screen 60.

[0096] Specifically, in some possible implementations, such as Figure 1 As shown, the sensor includes a water flow sensor installed on the first inlet pipe 30 and / or the drain pipe 40. The controller is used to control the opening and closing of the spray pump 50 and the opening and closing of the inlet valve 80 according to the water flow parameter value obtained by the water flow sensor.

[0097] In this embodiment of the application, by obtaining the flow rate of circulating water during the circulating spray washing, it is possible to indirectly reflect whether the filter screen is clogged.

[0098] Specifically, when the water flow rate is low, it indicates that the filter screen is clogged and needs to be cleaned. When the water flow rate is high, it indicates that the filter screen is not clogged and does not need to be cleaned.

[0099] Preferably, when the water flow sensor is installed on the drain pipe 40, it can more accurately detect the dirt and clogging of the filter screen.

[0100] Furthermore, in some possible implementations, a drainage assembly 300 is also connected to the first water inlet pipe 30;

[0101] The drainage component 300 is controlled to open when the spray pump 50 is closed and / or the inlet valve 80 is open.

[0102] In this embodiment of the application, when the filter screen 60 is backwashed, the cleaning water can be discharged through the drain assembly 300, thereby preventing the cleaning water from flowing back into the fabric treatment cylinder 10. The drain assembly includes a drain connector 301 and a drain valve 302. The opening and closing of the drain assembly 300 is achieved by controlling the opening and closing of the drain valve 302.

[0103] Furthermore, in some possible implementations, one end of the first water inlet pipe 30 away from the first water inlet 202 is connected to the bottom of the fabric treatment tube 10;

[0104] One end of the drain pipe 40 away from the drain outlet 203 is connected to the top of the fabric treatment tube 10;

[0105] The spray pump 50 is a booster pump installed on the drain pipe 40, used to pump the washing water discharged from the bottom of the fabric treatment cylinder 10 back into the fabric treatment cylinder 10 from the top of the fabric treatment cylinder 10.

[0106] Sensor 90 is located between the three-way structure 20 and the spray pump 50 to obtain the water flow rate parameter value in the drain pipe 40.

[0107] In this embodiment, by setting the spray pump 50 as a booster pump connected to the drain pipe 40, compared with the existing method of achieving the circulating spray washing effect through the drain pump, setting the booster pump on the drain pipe 40 can increase the spray water pressure during circulating spray washing and improve the spray washing effect on the underwear in the fabric treatment drum 10.

[0108] Furthermore, in some implementations, such as Figure 4 As shown, a pressure boosting plate 20121 is also provided in the second cavity 2012 of the three-way cavity 201. The pressure boosting plate 20121 is located between the second water inlet 204 and the filter screen 60.

[0109] The pressure plate 20121 is provided with multiple through holes 20122, which are used to pressurize the cleaning water flowing before the filter screen 60 when water enters through the second water inlet 204.

[0110] Specifically, by setting pressure boosting holes 20122 on the pressure boosting plate 20121, the water flow rate can be increased by reducing the cross-sectional area of ​​water flow per unit area, thus generating a certain flushing force. That is, when the water inlet valve 80 is opened to backwash the filter screen 60, the multiple through holes 20122 can accelerate and pressurize the cleaning water before it flows through the filter screen 60, thereby improving the backwashing effect of the filter screen 60.

[0111] Furthermore, in some possible implementations, such as Figures 2-9 As shown, the tee structure 20 includes a detachably connected tee front cover 20a and a tee rear cover 20b;

[0112] The tee front cover 20a has a drain outlet 203 at one end in the axial direction and a front cover connection structure 205 at the other end;

[0113] The tee back cover 20b has a back cover connection structure 206 formed at one end in the axial direction and a first water inlet 202 formed at the other end;

[0114] The front cover 20a of the three-way valve is sealed together by the front cover connecting structure 205 and the rear cover connecting structure 206 of the rear cover 20b of the three-way valve, and defines the three-way cavity 201 that connects the first water inlet 202 and the drain outlet 203.

[0115] In this embodiment, the T-junction structure 20 is configured as a separate structure to facilitate the assembly and disassembly of the T-junction structure 20.

[0116] Furthermore, in some possible implementations, such asFigures 3-8 As shown, the front cover connecting structure 205 includes a first slot formed on the axial end side of the three-way front cover 20a, and the rear cover connecting structure 206 includes a first hook formed on the axial end side of the three-way rear cover 20b. The first slot and the first hook are engaged together to fix the three-way front cover 20a and the three-way rear cover 20b together.

[0117] The front cover 20a and the rear cover 20b of the tee are also provided with sealing rings 207 at the mating positions. The sealing rings 207 are used to seal the connection position between the front cover 20a and the rear cover 20b of the tee.

[0118] In this embodiment of the application, a mating structure with a slot and a hook is provided between the front cover 20a and the rear cover 20b of the tee, which facilitates the installation of the two and prevents them from separating after they are installed together.

[0119] Furthermore, in some possible implementations, the tee back cover 20b has a second groove 208 formed at one end of the first inlet 202;

[0120] Fabric processing equipment also includes:

[0121] The filter cover 20c has a filter screen 60 and a second hook 209 that cooperates with the second slot 208.

[0122] The filter cap 20c is built into the back cover 20b of the tee and is fixed in the back cover 20b by the engagement of the second hook 209 and the second slot 208.

[0123] In this embodiment, a hook and slot structure is also provided between the three-way back cover 20b and the filter cover 20c, which can facilitate the installation of the two while preventing them from separating after being installed together.

[0124] Furthermore, in some possible implementations, such as Figures 2-8 As shown, the tee back cover 20b is also provided with a second water inlet 204, and the interior of the tee back cover 20b has a plurality of through holes 20122 located between the second water inlet 204 and the filter screen 60.

[0125] Furthermore, in some possible implementations, the fabric processing equipment described above can be a washing machine or a washer-dryer combo.

[0126] Specifically, taking the aforementioned fabric processing equipment as an example, such as a washing machine, the specific components of the three-way structure will be explained below:

[0127] like Figures 2-9As shown, the overall tee structure 20 includes a tee front cover 20a, a sealing ring 207, a tee rear cover 20b, a filter screen 60, and a filter screen cover 20c.

[0128] The front cover 20a of the tee is provided with a first connector, which forms a drain outlet 203 and is connected to a booster pump through a pipeline. The booster pump is then connected to a spray head through a pipeline, so that the circulating spray flow path is connected, and high-pressure spraying can be performed on the clothes. The front cover 20a of the tee is provided with a first hook, which restricts the movement of the front cover 20a of the tee and prevents it from loosening. The front cover 20a of the tee is provided with an installation groove, through which a sealing ring 207 is installed to prevent water leakage at the connection between the front cover 20a of the tee and the rear cover 20b of the tee. The front cover 20a of the tee is also provided with multiple first slots.

[0129] The T-shaped rear cover 20b is provided with a second connector, which forms a second water inlet and is connected to the water inlet valve 80 through a pipeline, so that the filter screen cleaning flow path is open and the filter screen 60 can be rinsed and cleaned. The T-shaped rear cover 20b is provided with multiple through holes 20122 for pressurization. The through holes 20122 pressurize the cleaning water flow, so as to clean the filter screen 60 more efficiently. The T-shaped rear cover 20b is provided with multiple first hooks, which cooperate with the first slots to fix the T-shaped front cover 20a.

[0130] The tee back cover 20b is provided with a third connector, which forms a first water inlet 202 and is connected to a drain flexible connector for communication with the bottom of the fabric treatment tube; the tee back cover 20b is also provided with multiple second slots.

[0131] The filter cover 20c is provided with multiple second hooks, which cooperate with the second slots to fix the filter cover 20c; preferably, when the filter cover 20c is formed, the filter screen 60 is simultaneously fixed on the filter cover 20c.

[0132] Furthermore, the second aspect of this application also provides a method for treating filter clogging in a fabric processing device, which is applied to the fabric processing device provided in the first aspect of this application. The fabric processing device has a circulating spray washing program. Under the circulating spray washing program, the spray pump is controlled to be turned on and the inlet valve is controlled to be turned off. The washing water in the fabric processing drum can enter the three-way cavity through the first inlet pipe, and after being filtered by the filter screen in the three-way cavity, it is pumped back to the fabric processing drum through the drain pipe.

[0133] Methods for dealing with clogged filters include:

[0134] Under the circulating spray washing program;

[0135] Obtain parameter values ​​to characterize the filter screen's clogging status, and control the opening and closing of the spray pump and the inlet valve based on these parameter values.

[0136] In this embodiment, by obtaining the dirt and clogging value of the filter screen 60, the opening and closing of the spray pump 50 and the water inlet valve 80 can be automatically controlled, thereby realizing the automatic detection and automatic cleaning effect of the dirt and clogging degree of the filter screen 60.

[0137] Furthermore, in some possible implementations, controlling the opening and closing of the spray pump and the inlet valve based on parameter values ​​includes:

[0138] If the parameter values ​​meet the requirements, control the opening and closing of the spray pump and the closing of the water inlet valve to continue the circulating spray washing program.

[0139] If the parameter values ​​do not meet the requirements, the spray pump is turned off and the inlet valve is turned on, so that while the circulating spray washing stops, cleaning water is injected into the three-way cavity through the second inlet pipe to backwash the filter screen.

[0140] When the filter screen becomes dirty and clogged, the circulating spray is stopped to perform a backwash cleaning of the filter screen. When the filter screen is not dirty and clogged, the circulating spray washing continues to operate, so as to improve the washing effect on the fabric of the tubular clothing.

[0141] Furthermore, in some possible implementations, the filter clogging treatment method also includes:

[0142] When the inlet valve is open and the spray pump is closed, the drainage assembly is activated.

[0143] In this embodiment of the application, when the filter screen 60 is backwashed, the cleaning water can be discharged through the drain assembly 300, thereby preventing the cleaning water from flowing back into the fabric treatment cylinder 10. The drain assembly includes a drain connector 301 and a drain valve 302. The opening and closing of the drain assembly 300 is achieved by controlling the opening and closing of the drain valve 302.

[0144] Furthermore, in some possible implementations, obtaining parameter values ​​used to characterize the filter clogging status includes:

[0145] Obtain the water flow rate value in the drain pipe, and control the opening and closing of the inlet valve and the spray pump based on the water flow rate value.

[0146] If the water flow rate is less than the preset water flow rate, the inlet valve will be opened and the spray pump will be shut down.

[0147] If the water flow rate is greater than or equal to the preset water flow rate, the inlet valve will be closed and the spray pump will be turned on.

[0148] In this embodiment of the application, by obtaining the flow rate of circulating water during the circulating spray washing, it is possible to indirectly reflect whether the filter screen is clogged.

[0149] Specifically, when the water flow rate is low, it indicates that the filter screen is clogged and needs to be cleaned. When the water flow rate is high, it indicates that the filter screen is not clogged and does not need to be cleaned.

[0150] Furthermore, in some possible implementations, the fabric treatment equipment also has a drainage procedure executed after the cyclic spray washing program has run, in which the drainage component is controlled to open and the spray pump is controlled to close, so as to discharge the washing water in the fabric treatment drum through the drainage component while stopping the cyclic spray washing.

[0151] Methods for dealing with clogged filters also include:

[0152] During the drainage process, the inlet valve is opened to inject cleaning water into the three-way cavity through the second inlet pipe to backwash the filter screen.

[0153] To better understand the control logic of the fabric treatment equipment in the washing program of this application embodiment, the following is combined with... Figure 10 Please provide a detailed explanation:
