[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0049] The water inlet box of a washing machine is an important component of the washing machine. In the prior art, the water inlet box is usually provided with a detergent delivery box inside and a water inlet for injecting water into the detergent delivery box. When the washing machine is taking in water, the water pressure of the water supply source of the washing machine may be too large or unstable, which may cause the water flow entering the detergent delivery box to be too turbulent. For the detergent in the detergent delivery box, when the turbulent water flow passes through the delivery box, the large kinetic energy of the water will cause the detergent to be quickly flushed into the washing tub before it has time to dissolve. If it is a solid detergent, it may not be flushed away due to adhesion to the box body, resulting in residue.

[0050] The present application embodiment provides a water inlet box assembly for a washing machine. For example, please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of the water inlet box assembly provided in an embodiment of the present application. Figure 2 for Figure 1 The water inlet box assembly 10 is a cross-sectional view along the AA direction. The water inlet box assembly 10 includes a box assembly 100 and a water retaining assembly 200 .

[0051] Among them, the box assembly 100 is formed with a water inlet chamber 110 and a delivery chamber 120 that are spaced apart. The water inlet chamber 110 is used to connect to an external water source, and the delivery chamber 120 is suitable for holding detergent and is used to connect to a washing tub; the water inlet chamber 110 and the delivery chamber 120 are connected via a water inlet 130; the water retaining assembly 200 is arranged at the water inlet 130 and is configured to move according to the water inlet time information of the washing machine to adjust the opening of the water inlet 130.

[0052] In actual application, water from an external water source can be injected into the water inlet chamber 110 and then enter the delivery chamber 120 through the water inlet 130. After the water is mixed with detergent in the delivery chamber 120, it will be delivered into the washing tub of the washing machine to wash the clothes.

[0053] It can be understood that on the one hand, the water retaining component 200 can play a buffering effect by blocking the water flow, thereby reducing the turbulence of the water flow. On the other hand, the water retaining component 200 can further control the water flow in the delivery chamber 120 by adjusting the opening of the water inlet 130, thereby extending the dissolution time of the detergent in the delivery chamber 120 and improving the dissolution rate.

[0054] The water inlet box assembly 10 of the washing machine provided in the embodiment of the present application, by adding a water retaining assembly 200 and controlling the movement of the water retaining assembly 200 according to the water inlet duration information to adjust the opening of the water inlet 130, can control the water flow rate and turbulence of the water flow in the delivery chamber 120 during the detergent delivery stage of the washing machine, thereby extending the time for the detergent to dissolve in the delivery chamber 120, and further achieving the effect of improving the dissolution rate of the detergent.

[0055] For example, see Figure 3 , Figure 3 for Figure 1 The exploded view of the water inlet box assembly is shown. The box assembly 100 includes a water box 140, a water dividing plate 150 and a detergent box 160. The water blocking assembly 200 includes a water blocking member 210 and a driving unit 220.

[0056] The water box 140 includes an upper shell 141 and a lower shell 142, and when the upper shell 141 and the lower shell 142 are assembled, a receiving chamber (not shown) with an installation port 143 is formed. A water injection port 1411 is provided on the upper shell 141, and a delivery port 1421 is provided on the lower shell 142. A water dividing plate 150 is arranged in the receiving chamber, and the receiving chamber is divided into a water inlet chamber 110 located above and an installation chamber 144 located below the water inlet chamber 110. Exemplarily, the water inlet chamber 110 is formed by the water dividing plate 150 and the upper shell 141. A water inlet 130 is provided on the water dividing plate 150, and the water inlet 130 communicates with the water inlet chamber 110 and the installation chamber 144. The detergent box 160 is slidably installed in the installation chamber 144, suitable for the user to pull in or out of the installation chamber 144. The detergent box 160 is provided with a delivery slot 161, in which detergent is placed. The delivery slot 161 is opened toward the water diversion plate 150 and communicated with the water inlet 130, and the bottom opening of the delivery slot 161 is communicated with the delivery port 1421 to form a delivery chamber 120. In some embodiments, the detergent box 160 also includes a storage chamber (not shown) suitable for storing detergent, and the storage chamber is also suitable for providing detergent to the delivery chamber 120. When the amount of detergent stored in the storage chamber is insufficient, the user can add detergent to the storage chamber by pulling the detergent box 160 out of the installation chamber 144.

[0057] Optionally, the water inlet 130 includes a plurality of water inlet holes 131. The water retaining member 210 is movably mounted on the box assembly 100, and the number of water inlet holes 131 blocked by the water retaining member 210 changes when the water retaining member 210 moves relative to the box assembly 100 to adjust the opening of the water inlet 130; the driving unit 220 includes an output shaft 221, which is transmission-connected to the water retaining member 210, and the driving unit 220 is used to drive the water retaining member 210 to move according to the water inlet time information of the washing machine. The driving unit 220 can be a micro motor.

[0058] For example, see Figure 4 , Figure 4 The schematic diagram of the structure of a water retaining assembly provided in an embodiment of the present application is shown in FIG. 1 . The water dividing plate 150 of the box assembly 100 includes a water inlet portion 151 with a water inlet 130 . The water retaining member 210 includes a water retaining plate 211 .

[0059] The water baffle plate 211 is slidably disposed on the water inlet portion 151 and is in transmission connection with the output shaft 221, and is used to be driven by the driving unit 220 to change the number of blocked water inlet holes 131. Exemplarily, a slide rail is connected to the water inlet portion 151 below the water-dividing plate 150, and a slide groove is disposed on the water baffle plate 211, and the slide groove cooperates with the slide rail so that the water baffle plate 211 is slidably connected to the water inlet portion 151. In order to prevent the driving unit 220 from contacting water, the driving unit 220 can be installed outside the box assembly 100, for example, fixedly installed on the outer wall of the upper shell 141. Optionally, a gear portion 2111 is provided at one end of the water baffle 211, and the gear portion 2111 is passed through the mounting port 143 and extends to the outside of the box assembly 100. A transmission gear is fixedly connected to the output shaft 221 of the driving unit 220, and the transmission gear is engaged with the gear portion 2111, so that the driving unit 220 drives the water baffle 211 through the gear portion 2111 to make the water baffle 211 slide relative to the water inlet portion 151.

[0060] In another embodiment, see Figure 5-Figure 7 , Figure 5 Another structural schematic diagram of the water inlet box assembly provided in an embodiment of the present application is shown in FIG. Figure 6 for Figure 5 An exploded view of the water inlet box assembly is shown. Figure 7 A schematic diagram of the structure of another water retaining assembly provided in an embodiment of the present application installed on a box assembly.

[0061] The water retaining member 210 includes a water retaining sheet 212, which includes a fixed end 2121 and a movable end 2122. The fixed end 2121 is fixed relative to the box assembly 100, and the movable end 2122 is adapted to be driven by the driving unit 220 to move so that the water retaining sheet 212 is unfolded or retracted, thereby changing the number of water inlet holes 131 blocked by the water retaining sheet 212. The water retaining sheet 212 may be a rolling curtain type water retaining sheet or a telescopic water retaining sheet.

[0062] Optionally, the water baffle 212 is a rolling curtain type water baffle. The fixed end of the water baffle 212 is fixedly connected to the output shaft 221 of the driving unit 220, and the movable end 2122 of the water baffle 212 is fixedly connected to the water diversion plate 150 through an elastic member such as a spring; the driving unit 220 is a rotating motor, which is suitable for rotating the water baffle 212 to roll up or unfold, so as to drive the movable end 2122 to move, and the elastic member is extended and retracted as the movable end 2122 moves. Among them, the movable end 2122 has an initial position. When the movable end 2122 is in the initial position, the water baffle 212 covers all the water inlet holes 131, so that the water inlet cavity 110 is not connected to the delivery cavity 120. When the rotating motor rotates along the first direction, the movable end 2122 is pulled and the water retaining sheet 212 is gradually rolled up, so that the number of opened water inlet holes 131 is gradually increased, thereby increasing the opening of the water inlet 130; when the rotating motor rotates along the second direction, the elastic member begins to recover its deformation to pull the movable end 2122 toward the initial position, and the water retaining sheet 212 is gradually unfolded, so that the number of opened water inlet holes 131 is gradually reduced, thereby reducing the opening of the water inlet 130.

[0063] To prevent the drive unit 220 from being damaged by contact with water, the drive unit 220 can be set outside the box assembly 100, for example, installed on the outer wall of the upper shell 141; the fixed end 2121 of the water retaining plate 212 is at least partially penetrated through the installation opening 143 and has a portion extending to the outside of the box assembly 100 and connected to the output shaft 221.

[0064] In another optional embodiment, the water retaining sheet 212 is a telescopic water retaining sheet, including a water retaining portion and an elastic telescopic portion, the fixed end 2121 is configured to be fixedly connected to the water dividing plate 150, and the movable end 2122 is configured to be connected to the output shaft 221 of the driving unit 220, and the driving unit 220 is a linear motor, which is used to directly drive the movable end 2122 to expand or retract the water retaining sheet 212. Among them, the movable end 2122 has an initial position, and when the movable end 2122 is in the initial position, the water retaining portion of the water retaining sheet 212 covers all the water inlet holes 131, so that the water inlet cavity 110 is not connected to the delivery cavity 120. When the linear motor transmits the movable end 2122 along the first direction, the elastic telescopic part is compressed, so that the number of water inlet holes 131 blocked by the water retaining sheet 212 gradually decreases, thereby increasing the opening of the water inlet 130; when the linear motor transmits the movable end 2122 along the second direction, the elastic telescopic part recovers the deformation and stretches, so that the number of water inlet holes 131 blocked by the water retaining sheet 212 gradually increases, thereby decreasing the opening of the water inlet 130.

[0065] The water inlet box assembly 10 of the washing machine provided in the embodiment of the present application, by adding a water retaining assembly 200 and controlling the movement of the water retaining assembly 200 according to the water inlet duration information to adjust the opening of the water inlet 130, can control the water flow rate and turbulence of the water flow in the delivery chamber 120 during the detergent delivery stage of the washing machine, thereby extending the time for the detergent to dissolve in the delivery chamber 120, and further achieving the effect of improving the dissolution rate of the detergent.

[0066] The present application also provides a method for controlling water inlet of a washing machine. The washing machine includes a water inlet box assembly 10 in any of the above embodiments. For example, see Figure 8 , Figure 8 This is a flow chart of a water inlet control method provided in an embodiment of the present application. The water inlet control method comprises the following steps S101 to S103:

[0067] Step S101: in response to a water inlet instruction for the washing machine, controlling the water blocking assembly 200 to open the closed water inlet to a target opening;

[0068] It should be noted that a washing machine is usually provided with a plurality of washing programs for the user to select, and the controller of the washing machine can execute the corresponding washing program according to the user's selection. The washing program usually includes washing steps such as water intake, washing, drainage, dehydration, and drying. When the washing machine enters the water intake stage based on the washing program, the controller, for example, issues a corresponding water intake instruction to control the water intake valve of the washing machine to open, so that the external water source can inject water into the water intake chamber.

[0069] In the initial state, the water retaining assembly 200 is located at the first preset position to completely close the water inlet, and before that, the water retaining assembly 200 may move to the first preset position in response to an instruction in the washing process of the washing machine, such as a washing end instruction.

[0070] Step S102: Control the water inlet chamber to start water inletting and obtain water inlet duration information;

[0071] Exemplarily, a water inlet valve is connected between the water inlet box assembly 10 and the external water source. Initially, the water inlet valve is closed. In response to a water inlet instruction for the washing machine, the water inlet valve is opened to allow water to flow into the water inlet chamber. The washing machine may be provided with a timing device for recording water inlet duration information.

[0072] Step S103: Control the movement of the water retaining assembly 200 according to the water inlet duration information to adjust the opening of the water inlet.

[0073] The water inlet control method of the washing machine provided in the embodiment of the present application can control the water flow rate and turbulence of the water flow in the delivery chamber 120 during the detergent delivery stage of the washing machine by adjusting the opening of the water inlet according to the water inlet duration information, thereby extending the time for the detergent to dissolve in the delivery chamber 120, and further achieving the effect of improving the dissolution rate of the detergent.

[0074] Regarding the specific control method of the opening of the water inlet, the present application provides the following embodiments, wherein the water retaining assembly 200 is controlled to move according to the water inlet duration information to adjust the opening of the water inlet, including:

[0075] After each water inlet cycle represented by the water inlet duration information, the water retaining component 200 is controlled to execute a preset motion strategy to increase the opening of the water inlet until the water inlet reaches the preset opening.

[0076] It should be noted that a water inlet stage of the washing machine includes multiple consecutive water inlet cycles. The duration of each water inlet cycle can be a set value, or it can be determined by the washing machine according to parameters such as the water inlet rate and the dosage of the detergent contained in the delivery chamber; in addition, the duration of multiple water inlet cycles can be the same or different. For example, in multiple water inlet cycles, the duration of each cycle increases relative to the previous cycle. When recording the water inlet duration information, the washing machine, for example, obtains the first target duration of the current water inlet cycle and starts the first timing. When the first timing duration reaches the first target duration, it indicates that a water inlet cycle has passed, and continues to obtain the second target duration of the next water inlet cycle to start the second timing of the next water inlet cycle. When the second timing duration reaches the second target duration, it indicates that a water inlet cycle has passed again, and so on until the recording of the water inlet duration information of multiple water inlet cycles is completed. Exemplarily, each water inlet cycle lasts for 30 seconds. When the timer reaches 30 seconds, it indicates that a water inlet cycle has passed, and the timer is reset and restarted. When the timer reaches 30 seconds again, it indicates that another water inlet cycle has passed.

[0077] Controlling the water retaining assembly 200 to execute the preset motion strategy means controlling the water retaining assembly 200 to move as expected so that the opening of the water inlet increases to an expected size. Exemplarily, controlling the water retaining assembly 200 to execute the preset motion strategy includes controlling the drive unit 220 to rotate in a preset clockwise direction for a preset time length so that the water retaining member 210 moves a preset distance in a first direction. For example, controlling the water retaining assembly 200 to execute the preset motion strategy includes controlling the drive unit 220 to rotate clockwise for 2 seconds so that the water retaining plate 211 slides 1 cm in a preset direction, thereby reducing the number of covered water inlet holes 131 by 10, thereby increasing the opening of the water inlet 130.

[0078] Among them, the preset opening can be the maximum opening that the water inlet 130 can reach, that is, every time the washing machine goes through a water inlet cycle, the opening of the water inlet 130 is increased to a set size until the opening of the water inlet 130 reaches the maximum opening, such as all the water inlet holes 131 are open.

[0079] It is understandable that the target opening is less than the preset opening. In actual application, when the washing machine receives the water inlet instruction, the water inlet 130 is first opened to a smaller opening, and then the water inlet is started. In the subsequent water inlet process, the water inlet 130 is gradually opened so that the water inlet 130 maintains a smaller opening for a period of time. It is understandable that when the opening of the water inlet 130 is small, the amount of water inlet into the delivery chamber 120 will be small and the water flow rate will be slow, which will not cause the detergent to be directly washed away, and the time for the detergent to dissolve in the delivery chamber 120 is extended. In some embodiments, a stirring device is also provided in the delivery chamber 120. When the washing machine is filled with water, the stirring device is started to mix the water and the detergent, thereby further increasing the dissolution rate of the detergent.

[0080] In some embodiments, during the water inlet cycle, the water inlet chamber 110 is filled with water within a first preset time, and the water inlet chamber 110 stops filling with water within a second preset time. It is understandable that during a water inlet cycle, the water inlet chamber 110 is in a water inlet state for a first preset time, and in a water inlet stop state for a second preset time, that is, during the water inlet stage, the water inlet chamber 110 has a period of intermittent water inlet. Among them, the first preset time may be shorter than the second preset time. Preferably, the second preset time is twice the first preset time. Exemplarily, the duration of each water inlet cycle is 30s. In the first 10s, the water inlet valve is controlled to be opened so that the water inlet chamber is in a water inlet state, and in the last 20s, the water inlet valve is controlled to be closed so that the water inlet valve is in a water inlet stop state.

[0081] It is understandable that by controlling the intermittent water inflow of the water inlet chamber 110, the amount of water entering the delivery chamber 120 each time is small, and a small amount of water cannot instantly wash away the detergent, but is mixed with the detergent under the stirring action of the impeller to dissolve part of the detergent, and finally the dissolved detergent is brought into the washing drum. In this way, the dissolution rate of the detergent can be improved, and a large amount of undissolved detergent can be prevented from flowing into the washing drum, resulting in blockage of the delivery channel, or the detergent is adhered to the detergent delivery box, which is not conducive to washing clothes.

[0082] Among them, for obtaining the target opening, the present application provides a method, before controlling the water retaining component 200 to open the closed water inlet 130 to the target opening, the water inlet control method also includes: obtaining the dosage of the detergent contained in the delivery cavity, and determining the target opening according to the dosage. It should be noted that the detergent contained in the delivery cavity is the detergent that is about to be put into the washing bucket for washing clothes, and the aforementioned dosage obtained represents the dosage of the detergent that is about to be put into the washing bucket, that is, the dosage of the detergent that is about to be dissolved. Exemplarily, the dosage of the detergent in the delivery cavity is negatively correlated with the target opening. For example, if the dosage is less than or equal to the first preset dosage, the target opening is 3 / 10 of the maximum opening, if the dosage is greater than the first preset dosage and less than or equal to the second preset dosage, the target opening is 1 / 5 of the maximum opening, and if the dosage is greater than the second preset dosage, the target opening is 1 / 10 of the maximum opening. In some other embodiments, the target opening can also be a set value such as 1 / 10 of the maximum opening.

[0083] Optionally, after the water inlet reaches a preset opening, the water inlet control method of the washing machine further includes controlling the water inlet chamber 110 to continue to inlet water until the water level in the washing tub reaches a set water level. The washing tub is provided with a liquid level sensor, for example, to detect the liquid level in the washing tub to determine whether the inlet water reaches the set water level. When it is detected that the water level in the washing tub reaches the set water level, for example, the water inlet valve is controlled to close, so that the water inlet chamber stops inletting water.

[0084] In order to better illustrate the water inlet control method of the washing machine of the present application, the present application provides the following embodiment, please refer to Fig. 9 , Fig. 9 Another flow chart of the water inlet control method of the washing machine provided in the embodiment of the present application. The water inlet control method includes the following steps S201-S207:

[0085] Step S201: Control the driving unit 220 to rotate clockwise for a first preset time to open the water inlet to 1 / 10 of the maximum opening;

[0086] It should be noted that when the driving unit 220 rotates clockwise, it drives the water retaining member 210 to move in a first manner, thereby increasing the opening of the water inlet 130; when the driving unit 220 rotates counterclockwise, it drives the water retaining member 210 to move in a second manner, thereby reducing the opening of the water inlet 130.

[0087] Step S202: Controlling the water inlet valve of the washing machine to open for a first preset time and then close for a second preset time;

[0088] It should be noted that one water inlet cycle is when the water inlet valve is opened for a first preset time and closed for a second preset time. Optionally, in the current water inlet cycle, the washing machine also controls the washing tub to rotate at a preset speed to further make the detergent more evenly distributed in the washing tub. The preset speed is, for example, 120rpm-150rpm.

[0089] Step S203: determining whether the water inlet has been opened to the maximum opening;

[0090] If it is detected that the water inlet has been opened to the maximum opening, the process proceeds to step S205 , otherwise it proceeds to step S204 , and after step 204 is completed, the process returns to step S202 .

[0091] As to how to determine whether the water inlet is opened to the maximum, a detection device such as a Hall sensor, a magnetic induction sensor or other types of sensors may be installed at the water inlet. The detection device may determine whether it is opened to the maximum by detecting the position of the water retaining member 210 .

[0092] Step S204: Control the driving unit 220 to rotate clockwise for a first preset time length, so that the opening of the water inlet increases to a set opening, and the set opening is 1 / 10 of the maximum opening;

[0093] Step S205: controlling the water inlet valve of the washing machine to remain open;

[0094] It is understandable that after water has been inletted for a period of time, substantially all of the detergent in the injection cavity 120 has been put into the washing tub, and the water inlet valve can be kept open to allow water to enter quickly, thereby avoiding excessively long washing time.

[0095] Optionally, a water level detection device such as a pressure type, ultrasonic type, capacitive type, photoelectric type, pressure difference type water level sensor, etc. is provided in the washing tub to detect the water level in the washing tub.

[0096] Step S206: determining whether the water level in the washing tub reaches a set water level;

[0097] If the water level in the washing tub reaches the set water level, the process proceeds to the following step S207, otherwise the process returns to step S205.

[0098] Step S207: Control the water inlet valve to close.

[0099] Optionally, while the water inlet valve is continuously opened to let in water, the washing machine also controls the washing tub to rotate at a preset speed for a preset time, such as 30 seconds, and then controls the washing tub to rotate forward and reverse according to a preset rhythm, for example, after each forward rotation for a third preset time, it stops rotating for a fourth preset time, and then reverses for a third preset time and stops rotating for a fourth preset time, and then repeats the above rotation steps until the water inlet is completed. In this way, the detergent can be further distributed more evenly in the washing tub, which is conducive to washing clothes. Among them, the third preset time is, for example, 8 seconds, and the fourth preset time is, for example, 5 seconds.

[0100] The water inlet control method of the washing machine provided in the embodiment of the present application can control the water flow rate and the turbulence of the water flow in the delivery chamber 120 during the detergent delivery stage of the washing machine by adjusting the opening of the water inlet according to the water inlet time information, thereby extending the time for the detergent to dissolve in the delivery chamber 120, and further achieving the effect of improving the dissolution rate of the detergent. In addition, in the early stage of the water inlet stage, the water retaining component 200 is controlled to open slowly, so that the water inlet 130 maintains a relatively small opening for a period of time, and at the same time, the water inlet chamber 110 is controlled to intermittently inlet water to reduce the water inlet amount and water flow rate in the delivery chamber 120, so as not to cause the detergent to be directly washed away, and to extend the time for the detergent to dissolve in the delivery chamber 120, and cooperate with the stirring device to stir and mix the detergent and water, effectively improving the dissolution efficiency of the detergent in the delivery chamber 120.

[0101] The present application also provides a water inlet control device for a washing machine, the washing machine comprising a water inlet box assembly 10 in any of the above embodiments, for example, see Fig.10 , Fig.10 A schematic diagram of the structure of the water inlet control device provided in an embodiment of the present application.
