Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular relates to a clothing processing equipment and a control method thereof. Background Art

[0002] With the improvement of people's living standards, the popularity of various types of intelligent clothing processing equipment is becoming higher and higher, and they are widely praised by users because they can complete most routine washing operations on behalf of users.

[0003] Currently, washing machines on the market usually mix detergent and water in the water tank and then send them into the washing chamber together. The water tank and the washing chamber are mostly connected by a U-shaped rubber tube. However, washing water and detergent residues are prone to occur at the lowest point of the U-shaped rubber tube, which can easily breed bacteria and affect the washing effect and the health of users. In addition, after the detergent enters the washing chamber, it may still be unevenly distributed due to sedimentation, affecting the washing effect.

[0004] In order to solve this problem, the Chinese invention patent with application number CN202010784225.6 discloses a laundry device, including a drum assembly, a clothing treatment agent delivery box and a liquid inlet pipe, the inlet of the liquid inlet pipe is connected with the clothing treatment agent delivery box, the outlet of the liquid inlet pipe is connected with the drum assembly, the laundry device also includes an air inlet pipe connecting the outside with the drum assembly and a water suction pipe connected to the liquid inlet pipe, the water suction pipe is connected to a drainage pump of the laundry device, an air inlet fan is provided in the air inlet pipe, and the drainage pump is configured to discharge the water in the liquid inlet pipe through the water suction pipe when the laundry device performs a ventilation program; the above scheme only realizes the discharge of residual water in the liquid inlet pipe through the water suction pipe, but cannot realize the circulation of washing water in the washing chamber, which is easily affected by the uneven distribution of detergent in the washing chamber. The cleaning effect.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a control method for a clothing processing equipment to address the problems in the above-mentioned prior art. The liquid inlet pipe is connected to the drain pump through a connecting pipe. After the detergent enters the washing chamber of the clothing processing equipment, the drain pump can connect the drain pipe with the connecting pipe through the drain pump, thereby realizing the circulation of washing water and avoiding detergent residue in the liquid inlet pipe affecting the washing effect.

[0007] In order to achieve the above-mentioned object, the first aspect of the present invention provides a control method for a clothes processing device, wherein the clothes processing device comprises a U-shaped liquid inlet pipe connecting a water tank with a washing chamber, and a liquid discharge pipe connecting the washing chamber with the outside, wherein the lowest part of the liquid inlet pipe is connected to a drainage pump provided on the liquid discharge pipe through a connecting pipe;

[0008] The control method is that, during the washing process, the control unit controls the drainage pump to connect the drainage pipe with the connecting pipe and circulate the washing water in the washing chamber.

[0009] In the above scheme, the control unit controls the drain pump to connect the drain pipe with the connecting pipe, and at the same time drives the water in the washing chamber to return to the inlet pipe through the drain pipe and the connecting pipe through the drain valve, and then returns to the washing chamber from the inlet pipe, thereby realizing the circulation of the washing water in the washing chamber, avoiding the residual detergent at the lowest point of the U-shaped inlet pipe, resulting in the detergent input amount not being able to fully meet the washing needs, and ensuring the washing effect.

[0010] It should be noted that the washing process in the present invention refers to the entire process from the user confirming the need for washing to the completion of washing.

[0011] Furthermore, the control method of the clothing processing device includes the following specific steps:

[0012] S1, detecting the progress of detergent delivery, and sending a signal to the control unit of the laundry processing device after the delivery is completed;

[0013] S2. After receiving the signal, the control unit controls the drain pump to connect the drain pipe with the connecting pipe to circulate the washing water in the washing chamber.

[0014] In the above scheme, when the washing liquid is not completely added, the washing water in the washing chamber is the tap water provided by the tap water pipe, which does not contain detergent, so there is no need to circulate; after detecting that the detergent is completely added, the water in the washing chamber is circulated, which improves the energy saving effect of the clothing processing equipment; after the detergent is added, the circulation is started immediately, and the detergent can be fully dissolved during the circulation process, avoiding the deposition and agglomeration of the detergent, and improving the washing effect. Further, in step S2, the drainage pump is intermittently controlled to circulate the washing water in the washing chamber.

[0015] In the above scheme, the drainage pump is intermittently controlled to circulate the washing water in the washing chamber, which increases the dissolution rate of the detergent and reduces the energy consumption of the clothing processing equipment, thereby achieving energy saving and emission reduction of the clothing processing equipment.

[0016] Furthermore, in step S2, the drain pump is controlled to circulate the washing water in the washing chamber at intervals of a preset first time length, and the duration of a single circulation of the washing water in the washing chamber is a preset second time length.

[0017] In the above scheme, by limiting the preset first time length and the preset second time length, that is, using a fixed cycle period to intermittently circulate the washing water in the washing chamber, the circulation control process is simplified and it can ensure that the circulation and dissolution of the detergent can be fully realized.

[0018] Preferably, the preset first duration is shorter than or equal to the preset second duration.

[0019] In the above scheme, the shorter the interval between two adjacent cycles, the better the dissolution effect of the detergent, and the better the residual detergent can be delivered to the washing chamber. Therefore, setting the preset first time length to be shorter than or equal to the preset second time length can improve the energy-saving effect of the clothing processing equipment while ensuring the circulation effect.

[0020] Furthermore, step S2 also includes detecting the detergent concentration at different positions in the washing chamber, determining that the detergent is unevenly distributed according to the detection result, and controlling the drainage pump to circulate the washing water in the washing chamber.

[0021] In the above scheme, the drainage pump is controlled to circulate the washing water in the washing chamber only when it is detected that the detergent in the washing chamber is unevenly distributed, thereby further improving the energy-saving effect of the clothes processing equipment.

[0022] Furthermore, during the cycle, the concentration change of the detergent in the washing chamber is continuously detected. After determining that the detergent is evenly distributed, the cycle is paused, and the detergent concentration in the washing chamber is continued to be detected. When uneven distribution of the detergent is detected again, the cycle is continued, and the above process is repeated until the washing is completed.

[0023] Furthermore, the concentration of detergent at the bottom of the washing chamber or in the drain pipe between the drain pump and the washing chamber is detected. If the concentration is greater than a preset threshold, it is judged that the detergent is unevenly distributed; conversely, if the concentration of the detergent is lower than a preset threshold, it is judged that the detergent is evenly distributed.

[0024] The second aspect of the present invention also provides a clothing processing device adopting the above-mentioned control method, the clothing processing device includes a U-shaped liquid inlet pipe connecting the water storage tank with the washing chamber, and a liquid discharge pipe connecting the washing chamber with the outside, and the lowest point of the liquid inlet pipe is connected to the drainage pump arranged on the liquid discharge pipe through a connecting pipe.

[0025] Furthermore, the drainage pump has three communication ports communicating with the outside, two of which are connected to connect the drainage pump to the drainage pipe, and the other communication port is connected to the communication pipe;

[0026] A regulating unit is arranged in the drainage pump, and any two of the three connecting ports are connected by controlling the regulating unit.

[0027] In the above scheme, the connection between any two connecting ports can be achieved through the regulating unit in the drain pump, and then during the washing process, the connecting pipe can be connected to the drain pipe at one end between the washing chamber and the drain valve, and the washing water in the washing chamber can be driven by the drain pump to circulate to the bottom of the U-shaped inlet pipe, and then the detergent deposited at the bottom is flushed into the washing chamber along the inlet pipe, thereby avoiding the deposition of detergent and resulting in insufficient detergent dosage, thereby ensuring the cleaning effect; when draining water, the two sections of the drain pipe located on both sides of the drain valve can be connected through the regulating unit, and then the water in the washing chamber can be quickly discharged; in order to avoid residual water that cannot be discharged at the lowest point of the U-shaped inlet pipe, the connecting pipe can be connected to a section of the drain pipe connected to the outside of the clothing processing equipment through the regulating unit, and then the residual water retained at the U-shaped inlet pipe can be discharged.

[0028] Furthermore, the clothing processing device also includes a control unit and a concentration detection unit, the concentration detection unit is used to detect the detergent concentration at the bottom of the washing chamber, and the concentration detection unit and the drainage pump are respectively communicatively connected to the control unit.

[0029] Furthermore, a control valve is provided at one end of the connecting pipe connected to the bottom of the U-shaped liquid inlet pipe, and the control valve is communicatively connected with the control unit.

[0030] In the above solution, the opening and closing of the connecting pipe is controlled by the control valve, so that the connecting pipe can be prevented from affecting the liquid inlet process.

[0031] The beneficial effects of the present invention are:

[0032] 1. During the washing process of the clothing processing equipment, after detecting that the detergent has been added, the drain pipe is connected to the connecting pipe by controlling the drain pump to realize the circulation of the washing water in the washing chamber. On the one hand, the dissolution efficiency of the detergent is improved. On the other hand, the washing water flowing out of the drain pipe returns to the inlet pipe through the connecting pipe, and the detergent remaining at the bottom of the U-shaped inlet pipe is flushed into the washing chamber, avoiding the problem of insufficient detergent addition and ensuring the washing effect.

[0033] 2. During the washing process, the drainage pump is intermittently controlled to circulate the washing water in the washing chamber, which reduces the power consumption of the clothing processing equipment; at the same time, by circulating the washing water in the washing chamber, the detergent is fully dispersed, thereby improving the washing effect.

[0034] 3. By detecting the concentration of detergent in the washing chamber and judging whether the detergent is evenly dispersed according to the concentration, the power consumption of the clothing processing equipment is further reduced, which can better ensure the full dispersion of the detergent and further improve the washing effect.

[0035] 4. By controlling the connection of any two of the three connecting ports of the drain valve through the regulating unit arranged in the drain valve, not only can the circulation of the washing water in the washing chamber be realized without affecting the normal drainage, but also the residual water can be discharged by extending the connecting pipe and the drain pipe to a section outside the clothing processing equipment.

Those skilled in the art will appreciate that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] The present invention provides a clothes processing device and a control method thereof. Figures 1 to 4As shown, the clothes processing device includes a U-shaped liquid inlet pipe 3 connecting the water storage tank 2 with the washing chamber, and a liquid discharge pipe 7 connecting the washing chamber with the outside, and the lowest part of the liquid inlet pipe is connected to a drainage pump 8 provided on the liquid discharge pipe 7 through a connecting pipe 4;

[0045] The control method is that, during the washing process, the control unit controls the drainage pump 8 to connect the drainage pipe 7 with the connecting pipe 4 and circulate the washing water in the washing chamber.

[0046] In the above scheme, the control unit controls the drain pump 8 to connect the drain pipe 7 with the connecting pipe 4, and at the same time drives the water in the washing chamber to return to the inlet pipe through the drain pipe 7 and the connecting pipe 4 through the drain valve, and then returns to the washing chamber from the inlet pipe, thereby realizing the circulation of the washing water in the washing chamber, avoiding the residual detergent at the lowest point of the U-shaped inlet pipe 3, resulting in the detergent input amount not being able to fully meet the washing needs, and ensuring the washing effect.

[0047] The present invention is further described in detail below with reference to specific embodiments.

[0048] Embodiment 1

[0049] As an embodiment of the present invention, this embodiment provides a control method for a clothes processing device, such as Figure 1 As shown, the following steps are included:

[0050] S1, detecting the progress of detergent delivery, and sending a signal to the control unit of the laundry processing device after the delivery is completed;

[0051] S2. After receiving the signal, the control unit controls the drainage pump 8 to connect the drainage pipe 7 with the connecting pipe 4 to circulate the washing water in the washing chamber.

[0052] Specifically, after the user controls the clothing processing equipment to start executing the washing program, it first enters the water intake stage, and detergent is automatically added to the washing chamber while the water is intaken. After detecting that the detergent has been added, the control unit controls the drain pump 8 to connect the drain pipe 7 with the connecting pipe 4 and drive the drain pump 8 to work, continuously extracting the washing water from the bottom of the washing chamber and pumping it into the U-shaped inlet pipe 3 of the inlet pipe, and then returning to the washing chamber through the inlet pipe, thereby realizing the circulation of the washing liquid. The solubility of the detergent can be improved during the circulation process. At the same time, when the washing water circulates to the bottom of the U-shaped inlet pipe 3, the detergent deposited at the bottom of the U-shaped inlet pipe 3 can be brought up and flushed into the washing chamber in one go, thereby ensuring the accuracy of the detergent addition amount and avoiding the reduction of the washing effect due to insufficient actual detergent addition amount.

[0053] Furthermore, in order to reduce the energy consumption of the clothing processing equipment while ensuring that the detergent is fully dispersed and dissolved, the drainage pump 8 is intermittently controlled in step S2 to circulate the washing water in the washing chamber, thereby reducing the circulation time while ensuring that the detergent is fully dissolved and dispersed, thereby reducing the energy consumption of the clothing processing equipment.

[0054] Specifically, in step S2 of this embodiment, if Figure 2 As shown, the drain pump 8 is controlled to circulate the washing water in the washing chamber at intervals of a preset first time period, and the duration of a single cycle is a preset second time period. This scheme fixes the circulation period of the washing water and simplifies the control method of the circulation. In order to ensure sufficient circulation of the washing water while reducing energy consumption, the preset first time period is generally shorter than or equal to the preset second time period, that is, the second time period accounts for at least 50% of the circulation period, so as to achieve a balance between the circulation effect and the energy consumption of the clothing processing equipment and improve the user experience.

[0055] Embodiment 2

[0056] As another embodiment of the present invention, this embodiment differs from the first embodiment in that the determination method for controlling the drain pump 8 to circulate the washing water in the washing chamber is different.

[0057] In step S2 of this embodiment, Figure 3 As shown, after receiving the signal, the control unit first detects the detergent concentration in the washing chamber, and after judging that the detergent is unevenly distributed according to the detergent concentration, starts to circulate the washing water in the washing chamber; here, there are two ways to judge the uneven distribution of detergent according to the detergent concentration. The first is to obtain the concentration at different positions in the washing chamber, and judge whether the detergent is evenly distributed according to the concentration difference at different positions; the second is to detect the detergent concentration near the bottom of the washing chamber, compare the detergent concentration with the preset threshold value, and judge whether the detergent is evenly distributed according to the comparison result; at this time, the preset threshold value is a theoretical value calculated according to the amount of detergent added and the amount of washing water inlet; the second method is taken as an example for further detailed explanation.

[0058] The theoretical concentration of the detergent is calculated based on the amount of detergent added and the amount of washing water, and is defined as a preset threshold value. Then, the detergent concentration near the bottom of the washing chamber is obtained and compared with the preset threshold value. If the detergent concentration is less than or equal to the preset concentration, it is judged that the detergent is evenly distributed; if the detergent concentration is greater than the preset threshold value, it is judged that the detergent is unevenly distributed. At this time, the control unit controls the drain pump 8 to connect the connecting pipe 4 with a section of the drain pipe 7 between the washing chamber and the drain pump 8, and circulates the washing water in the washing chamber through the drain pump 8.

[0059] Furthermore, if the detergent concentration is detected to be less than or equal to a preset concentration during the water inlet process, the detergent may not have settled to the bottom because the water inlet has not yet been completely completed. Therefore, the detergent concentration needs to be continuously detected during the washing process, and when the detergent is found to be deposited below the washing chamber, the detergent should be fully dispersed by circulating the washing water.

[0060] This embodiment determines whether to circulate washing water based on concentration, and can selectively circulate washing water according to actual needs, further optimizing the washing capacity of the clothing processing equipment and further reducing the energy consumption of the clothing processing equipment.

[0061] Alternatively, as an alternative to the above-mentioned solution, the concentration of the detergent in the drain pipe 7 between the drain pump 8 and the washing chamber can also be detected to determine whether the detergent is evenly distributed. The lower the detection position, the higher the judgment accuracy. The conventional replacement of the detection position, detection mode and judgment method by those skilled in the art based on the known technical principles of the present invention also falls within the protection scope of the present invention.

[0062] The present invention also provides a clothes processing device, which adopts the control method described in the above embodiment, which is specifically as follows:

[0063] Embodiment 3

[0064] As another embodiment of the present invention, this embodiment provides a clothes processing device using the control method described in the second embodiment.

[0065] In this embodiment, if Figure 4 As shown, taking a conventional drum washing machine as an example, the washing chamber includes an outer drum 5 and an inner drum 6, and the liquid inlet pipe and the liquid discharge pipe 7 are respectively connected to the outer drum 5. The washing chamber in this embodiment refers to the outer drum 5; for washing machines with different structures, the structure referred to by the washing chamber is different, and the conventional changes made to the structure of the clothing processing equipment by technicians in this field on this basis also fall within the protection scope of the present invention.

[0066] Furthermore, the clothing processing device includes a U-shaped liquid inlet pipe 3 connecting the water storage tank 2 with the washing chamber, and a liquid discharge pipe 7 connecting the washing chamber with the outside. The lowest point of the liquid inlet pipe is connected to a drainage pump 8 arranged on the liquid discharge pipe 7 through a connecting pipe 4, and a dispenser 1 is also connected to the upstream of the water storage tank 2; the drainage pump 8 has three connecting ports connected to the outside, and the drainage pump 8 is connected to the liquid discharge pipe 7 by connecting two of the connecting ports, and the other connecting port is connected to the connecting pipe 4; an adjusting unit is provided in the drainage pump 8, and any two of the three connecting ports are connected by controlling the adjusting unit; thus, different functions can be realized by connecting different connecting ports.

[0067] For the sake of convenience of explanation, in this embodiment, the connecting port connected to the connecting pipe 4 is defined as the first connecting port, the connecting port connected to a section of the drain pipe 7 between the washing chamber and the drain valve is defined as the second connecting port, and the connecting port connected to a section of the drain pipe 7 extending to the outside of the clothing processing device is defined as the third connecting port.

[0068] Specifically, when the washing water needs to be circulated, the regulating unit will be connected to the first connecting port and the second connecting port, thereby realizing the smooth circulation of the washing water. At this time, the third connecting port is closed to avoid direct discharge of the washing water, thereby ensuring smooth washing.

[0069] When drainage is required, the regulating unit connects the second connecting port and the third connecting port to achieve smooth drainage of the washing water in the washing chamber. At this time, the first connecting port is closed and the washing water will not return to the washing chamber through the connecting pipe 4.

[0070] When residual water needs to be discharged, the regulating unit connects the first connecting port and the third connecting port, and the residual washing water in the U-shaped liquid inlet pipe 3 can be directly discharged through the connecting port, avoiding the residual washing water and the generation of bacteria that affect the health of the user, thereby improving the user's experience.

[0071] In order to achieve the above functions, the regulating unit in the drain valve can be a solenoid valve that controls the three connecting ports respectively, or it can be set as a rotatable baffle, which can block the washing water from entering the third connecting port while connecting two of the connecting ports; the conventional improvements to the drain valve structure made by technical personnel in this field based on the known technical principles of the present invention also fall within the scope of protection of the present invention.

[0072] Furthermore, the clothing processing device also has a control unit and a concentration detection unit. The concentration detection unit is used to detect the concentration of detergent in a section of the drain pipe 7 at the bottom of the washing chamber or between the drain valve and the washing chamber. The concentration monitoring unit and the drain valve are both connected to the control unit for communication. After receiving the concentration of the detergent, the control unit determines whether the detergent is evenly dispersed, and when it is determined that the detergent is not evenly dispersed, controls the regulating unit to connect the first connecting port and the second connecting port, and at the same time controls the drain valve to operate to draw the washing water in the washing chamber from the drain pipe 7 at the bottom of the washing chamber, and send it back to the washing chamber from the inlet pipe at the top, thereby realizing the circulation of the washing water.

[0073] Furthermore, a control valve is provided at one end of the connecting pipe 4 connected to the bottom of the U-shaped liquid inlet pipe 3. The control valve is communicated with the control unit, so that the control valve always remains closed during the water inlet stage, and the washing water does not directly enter the drain valve from the connecting pipe 4, thereby ensuring the smooth water inlet; during the residual water discharge and circulation process, the control valve is opened to ensure the smooth residual water discharge and circulation.

[0074] The clothing processing device in this embodiment can also be combined with the control method described in Example 1, and the combined solution can also solve the corresponding technical problems. The solution obtained by combining this embodiment with Example 1 also falls within the protection scope of the present invention.

[0075] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
