DETAILED DESCRIPTION

[0042] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0043] In the specific embodiments, various specific technical features described can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of various specific technical features in the present application are not described again.

[0044] In the following description, the terms "first", "second", and the like are only used to distinguish different objects, and do not mean that there is the same or relationship between the objects. It should be understood that the terms "upper", "lower", "outer", "inner", "left", and "right" are the positions of the objects in the normal use state, and the "left" and "right" directions shown in the specific corresponding schematic diagram can be the left and right directions in the normal use state or not.

[0045] It should be noted that the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus including a series of elements includes not only those elements, but also other elements not explicitly listed, or other elements inherent to such a process, method, article, or apparatus. Without more limitations, the element defined by the statement "including a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus including the element. "Multiple" means greater than or equal to two.

[0046] The embodiment of the present application provides a stirring piece, such as Figure 1As shown, the stirring component 5 includes a base 51 and blades 52. (Combined) Figure 2 As shown, the base 51 has a through hole 53 in the first direction, meaning that the through hole 53 connects the base 51 in the first direction ( Figure 1 The two end faces (in the left and right directions indicated by the arrows). One end of the through hole 53 ( Figure 1 The right end shown is positioned opposite to the blade 52, meaning that the water flow from the through hole 53 can directly impact the surface of the blade 52, allowing the water flow to flow along the surface of the blade 52.

[0047] like Figure 3 and Figure 4 As shown, blade 52 rotates in the first direction ( Figure 3 The spiral (shown in the left-right direction) is located on one side of the base 51. Figure 3 As shown on the right, during the flow of liquid through the agitator 5, the blades 52 are fixed, and the liquid changes its direction of movement along the spiral shape of the blades 52. It should be noted that the blades 52 are designed with a spiral curved structure; that is, the blades 52 are not merely smooth curved surfaces, but also have an overall torsional shape. Therefore, when the mixed liquid containing the detergent flows over the surface of the blades 52, the mixed liquid undergoes a torsional motion along the surface of the blades 52. Influenced by the surface shape of the blades 52, the flow velocity and direction of the mixed liquid change at various points on the surface of the blades 52. During the torsional process along the surface structure of the blades 52, the mixed liquid generates a rapid inertial force, causing turbulence under the action of forces in different directions, resulting in more thorough mixing of the liquid. In this embodiment of the invention, the agitator is fixed, meaning it is statically set and does not need to rotate, which helps reduce the damage rate of the agitator and extend its service life.

[0048] It should be noted that the embodiments of the present invention do not limit the specific structure of the blade 52. It can be considered that the blade 52 is relatively thin and is a structure obtained by twisting a two-dimensional planar component. For example, a rectangular thin plate is used to apply torque in opposite directions along its length (for example, applying a clockwise torque at one end and a counterclockwise torque at the other end) to obtain a structure in which the blade 52 approximately forms an X-shaped structure in space. Of course, the blade 52 can also be formed by twisting a semi-circular approximately planar component. In other embodiments, the blade 52 can also be formed by twisting other shapes. Regardless of the shape in which the blade 52 is twisted, as long as the liquid flowing along the blade can cause the liquid to twist and change direction, it is acceptable.

[0049] In some embodiments, such as Figure 3 and Figure 4As shown, the stirring member 5 has a plurality of blades 52, and the helical directions of adjacent blades are opposite. For example, when the mixed liquid flows through the stirring member 5, the mixed liquid moves along one blade 52, and the moving direction of the mixed liquid is substantially consistent with the helical direction of the blade 52. When the mixed liquid moves from the blade 52 to the adjacent blade 52, the helical direction of the adjacent blade 52 changes, so that the moving direction of the mixed liquid changes. It can be considered that the moving direction of the mixed liquid in the adjacent blade 52 is opposite to the moving direction of the mixed liquid in the blade 52 (for example, the mixed liquid moves clockwise in the blade 52, and the mixed liquid moves counterclockwise in the adjacent blade 52). In the embodiment of the application, the opposite moving directions of the fluid are not the absolute opposite directions of the velocity of the fluid at each point on the adjacent blades 52. It can be understood that, because the helical directions of the adjacent blades 52 are opposite, the rotating direction of the fluid flowing through the blades 52 is deflected, and the rotating directions of the fluid on the two adjacent blades 52 are opposite. In some embodiments, the structure, length, and shape of each blade 52 can be different, as long as the helical directions are opposite. In other embodiments, the structures of the adjacent blades 52 can be completely the same. It can be understood that, if each blade 52 can be separated into an independent piece, each blade 52 can be stacked and the stacking surfaces coincide, and the adjacent blades 52 in the stirring member 5 are arranged by changing the angles of the blades 52 with the same structure. It can be understood that the corresponding phases of the starting edges of the adjacent blades 52 have an angle difference. For example, referring to FIG. 2, the first blade 52 and the second blade 52 have the same structure and shape. From left to right, the extending direction of the first edge of the starting edge of the first blade 52 is opposite to the extending direction of the first edge of the starting edge of the second blade 52, so that, from left to right, the fluid flowing through the first blade 52 rotates clockwise around the up-down direction shown in FIG. 2, and the fluid flowing through the second blade 52 rotates clockwise around the left-right direction shown in FIG. 2. Figure 4 As shown, the fluid flows from the left side of the figure to the right side through the plurality of blades 52, Figure 4 Two blades 52 are shown schematically. The structures and shapes of the two blades 52 are the same. From left to right, the extending direction of the first edge of the starting edge of the first blade 52 is opposite to the extending direction of the first edge of the starting edge of the second blade 52, so that, from left to right, the fluid flowing through the first blade 52 rotates clockwise around the up-down direction shown in FIG. 2, and the fluid flowing through the second blade 52 rotates clockwise around the left-right direction shown in FIG. 2. Figure 3 As shown, the fluid flows from the left side of the figure to the right side through the plurality of blades 52, Figure 4 As shown, the fluid flows from the left side of the figure to the right side through the plurality of blades 52, Figure 4 As shown, the fluid flows from the left side of the figure to the right side through the plurality of blades 52,

[0050] In this embodiment of the invention, the spiral directions of adjacent blades in the agitator are opposite. As the mixed liquid flows through the agitator, it moves along the spiral direction of the blades. Since the speed and direction of the mixed liquid at different points on the blades are different, the mixed liquid at the center and outer edge of the blades can be stirred together. The change in the spiral direction of adjacent blades will also cause the mixed liquid to reverse and exchange under the action of a sudden inertial force. Under the action of the agitator, the washing substance can be fully mixed and dissolved with water, which improves the disturbance effect of the mixed liquid, which is beneficial to improve the utilization rate of the washing substance and reduce the amount of washing substance used.

[0051] In some embodiments, such as Figure 4 As shown, the adjacent edges of two adjacent blades 52 extend perpendicularly. Figure 4 The stirring element 5 in the illustrated embodiment is in the first direction ( Figure 4 Multiple blades are provided in the left-right direction (as shown). Adjacent blades 52 refer to the two blades that are closest to each other in the first direction among the multiple blades 52. Each blade 52 in the first direction ( Figure 4 It has two ends in both the left and right directions (as shown), one of which ( Figure 4 The left end shown is the first edge 521 of the blade 52, and the other end ( Figure 4 The right end shown is the second edge 522 of blade 52. The first edge of each blade is adjacent to the second edge of another blade, as shown. Figure 4 In the two adjacent blades shown, the second edge 522 of the left blade is adjacent to the first edge 521 of the right blade, and the extension direction of the second edge 522 of the left blade is perpendicular to the extension direction of the first edge 521 of the right blade. It should be noted that the first edge or the second edge can be regarded as a two-dimensional planar figure, and the extension direction represents the length direction of the first edge. Figure 4 (in the direction indicated by the dashed line b) or the length direction of the second edge ( Figure 4 (The direction indicated by the dashed line a). In this embodiment of the invention, the second edge of an adjacent blade being substantially perpendicular to the first edge includes cases where the extension direction of the second edge is not strictly 90 degrees from the extension direction of the first edge. It can be considered that the angle between the two directions is greater than 80 degrees as substantially perpendicular, thus covering the situation of processing and installation errors. Of course, in other embodiments, the extension directions of the adjacent edges of two adjacent blades can also be set at an acute angle, as long as the adjacent edges intersect.

[0052] Combination Figure 5 The stirring principle of the stirring element for fluid in the embodiments of the present invention will be explained below:

[0053] The adjacent edges of two adjacent blades (the second edge of one blade and the first edge of another adjacent blade) extend perpendicularly, for example... Figure 5The second edge 522 of the first vane on the left side is substantially perpendicular to the first edge 521 of the second vane on the left side, and the second edge of the second vane is substantially perpendicular to the first edge of the third vane. When the mixed liquid flows from the first vane to the second vane, due to the fact that the first edge 521 of the second vane is perpendicular to the second edge 522 of the first vane, the liquid flowing to the second edge 522 of the first vane is divided into two streams by the first edge 521 of the second vane, and the two streams flow along the two side surfaces of the second vane, respectively. Figure 5 The solid arrows on the left side in the middle represent the mixed liquid flowing along the back surface of the first vane, and the dashed arrows represent the mixed liquid flowing along the front surface of the first vane. The mixed liquid flowing along the front surface of the first vane (indicated by the dashed arrows) is divided into two streams by the upper part of the first edge 521 of the second vane when the mixed liquid flows to the second edge 522 of the first vane, and the two streams flow along the two side surfaces of the second vane from the upper part, respectively. The mixed liquid flowing along the back surface of the first vane is divided into two streams by the lower part of the first edge 521 of the second vane when the mixed liquid flows to the second edge 522 of the first vane, and the two streams flow along the two side surfaces of the second vane from the lower part, respectively. The four streams of liquid entering the second vane flow along different positions of the second vane, respectively, and the four streams of liquid can exchange with each other under the surface twisting action of the second vane. Moreover, each stream of liquid is divided into two streams by the first edge of the third vane when the stream of liquid flows to the second edge 522 of the second vane, and finally the four streams of liquid are divided into eight streams of liquid by the third vane. By arranging the extending directions of the adjacent edges of adjacent vanes to be perpendicular to each other, the adjacent vanes can continuously divide the mixed liquid, so that the efficiency of dissolving the washing material in water is improved. Moreover, the mixed liquid changes the flowing direction under the helical directions of different vanes, so that the liquid is subjected to the reverse action. The liquid also produces the effect of flowing from the center to the outer edge or flowing from the outer edge to the center during the flow through the same vane. Under the multiple actions, the mixing effect of the washing material and water is improved, and the dissolving efficiency of the washing material is improved.

[0054] The embodiment of the present application also provides a mixing device which can be applied to washing equipment such as laundry treatment equipment, dish washing equipment, fruit and vegetable cleaning equipment, etc. The mixing device in the embodiment of the present application is used to stir the washing material and water, so that the washing material and water are fully mixed and dissolved, and the washing effect of the washing equipment is improved. It should be noted that the application scenarios of the embodiment of the present application do not limit the structure of the mixing device in the embodiment of the present application.

[0055] As Figure 6 , Figure 7 and Figure 9As shown, the mixing device comprises a body 4 and a stirring member 5. As shown in Figure 7 As shown, the body 4 is internally provided with a cavity 10, which can be used to accommodate washing substances such as laundry detergent, disinfectant and laundry powder. The body 4 is provided with a first water inlet 11, a second water inlet 12 and a water outlet 13 which communicate with the cavity 10. The first water inlet 11 is arranged at the top of the cavity 10, and the second water inlet 12 and the water outlet 13 are arranged at the bottom of the cavity 10. It should be noted that the top and the bottom in the embodiment of the present application represent the top and the bottom of the mixing device in the normal use state. The stirring member 5 is arranged in the cavity 10 and is used to stir the mixed liquid in the cavity 10. It should be noted that the specific arrangement type of the stirring member 5 is not limited in the embodiment of the present application. The stirring member 5 can be stationary relative to the cavity 10, the seat body 51 is fixedly connected to the body 4, then the stirring member 5 is also stationary relative to the body 4, and the blade 52 is also stationary relative to the cavity 10. The stirring member 5 changes the movement direction of the liquid flowing through the surface of the stirring member 5 by changing its own structure. In the embodiment of the present application, the stirring member is fixed in the cavity, and the stirring member is a static component. The stirring member does not need to rotate, which is conducive to reducing the damage rate of the stirring member and prolonging the service life of the stirring member.

[0056] In the embodiment of the present application, the first water inlet and the second water inlet of the mixing device are arranged at the top and the bottom of the cavity respectively. The water flowing from the first water inlet at the top of the cavity can impact the washing substances in the direction of the bottom of the cavity under the action of gravity. The water flowing from the second water inlet at the bottom of the cavity can impact the washing substances deposited at the bottom of the cavity in the horizontal direction under the action of the inertia of the water flow. The stirring member located in the cavity can also disturb the mixed liquid. The cavity forms water flows in different directions under the combined disturbance of the first water inlet, the second water inlet and the stirring member. The water flows disturb each other, which improves the mixing efficiency of the washing substances and water.

[0057] In some embodiments, as shown in Figure 9 and Figure 1 The stirring member 5 comprises a seat body 51 and a blade 52. The seat body 51 is provided with a through hole 53 which penetrates in a first direction, and the blade 52 is spirally arranged on one side of the seat body 51 (the right side of the seat body) around the first direction (the left-right direction in Figure 1 The through hole 53 is opposite to the blade 52. Specifically, the seat body 51 is fixed at the bottom of the cavity 10, and the through hole 53 communicates with the second water inlet 12. Specifically, one end of the through hole 53 (the left end of the through hole 53) is arranged at the bottom of the cavity 10, and the other end of the through hole 53 (the right end of the through hole 53) is arranged at the top of the cavity 10. Figure 9The second water inlet 12 is communicated with the through hole 53 at the left end as shown. Of course, in some embodiments, the through hole 53 can be provided as an extension body with a certain length, and then the extension body can be arranged in the second water inlet 12. In this case, one end of the through hole 53 can be connected to the second water inlet pipe. It should be noted that no matter whether the through hole 53 is connected to the second water inlet or the second water inlet pipe, as long as water can be guided to flow through the through hole 53. The first direction is the direction in which the second water inlet 12 faces the water outlet 13. In the embodiment of the present application, the second water inlet is communicated with the through hole, so that the water flow introduced by the second water inlet directly impacts on the blade through the through hole, and the water flow flows along the surface of the blade at the bottom of the cavity. The water flow introduced by the first water inlet also stirs the mixed liquid in the cavity, and the water flows stir each other, thereby improving the mixing efficiency of the washing material and water.

[0058] In some embodiments, as shown in Figure 7 The mixing device further includes a detergent box 14 and a mixing part 15. The inside of the detergent box 14 forms a part of the cavity 10. The first water inlet 11 is connected to the detergent box 14, that is, the first water inlet 11 is communicated with the inside of the detergent box 14. The inside of the detergent box 14 is a part of the cavity 10. The detergent box 14 can be used to contain washing materials. The first water inlet 11 can introduce water into the detergent box 14 to achieve the preliminary mixing of water and washing materials. The mixing part 15 is arranged below the detergent box 14. It should be noted that the below in the embodiment of the present application means the below in the normal use state of the detergent box. The mixing part 15 forms another part of the cavity 10. The part in the detergent box 14 and the other part formed by the mixing part 15 are communicated and jointly form the cavity 10 of the mixing device. The second water inlet 12 and the water outlet 13 are connected to the mixing part 15, that is, the water introduced by the second water inlet 12 can directly flow into the below of the detergent box 14, that is, the bottom of the cavity 10. The mixed liquid mixed in the inside of the detergent box 14 flows into the mixing part 15. The mixed liquid in the mixing part 15 is secondarily impacted by the water introduced by the second water inlet 12, thereby improving the mixing efficiency of water and washing materials. The mixed liquid at the bottom of the cavity 10 can be guided out of the water outlet 13. In the embodiment of the present application, the first water inlet is connected to the detergent box, the second water inlet and the water outlet are connected to the mixing part, and the mixing part is arranged below the detergent box, so that the washing materials can be stirred multiple times in the cavity, thereby improving the stirring efficiency.

[0059] In some embodiments, as shown in Figure 7 The detergent box 14 is provided with an opening 16 communicated with the cavity 10 at one end (the left end) in the first direction (the direction of the arrow as shown). Figure 7 The mixing device further includes a bucket 17. The bucket 17 is inserted into the cavity 10 through the opening 16 and can be relatively moved with the detergent box 14 in the first direction (the direction of the arrow as shown). Figure 7The drawer 17 moves in the direction of the arrow shown to open and close the opening 16. The drawer 17 has a receiving cavity 171 for holding detergent. A first water inlet 11 communicates with the receiving cavity 171. At least one side of the drawer 17 is open to allow the user to add detergent to the receiving cavity 171. When the drawer 17 is in the state of being inside the cavity 10, the drawer 17 closes the opening 16 of the detergent dispenser 14, so that the cavity 10 is substantially closed. The drawer 17 moves in a direction away from the cavity 10 (…). Figure 7 When the device moves to the right (as shown), the drawer 17 is opened, and the opening 16 of the cavity 10 is also opened, allowing the user to add detergent to the receiving cavity 171. The receiving cavity 171 is connected to the cavity 10, so the detergent in the receiving cavity 171 will mix with the water under the impact of the water flow introduced through the first water inlet 11 to form a mixed liquid, which will then flow into the cavity 10. It should be noted that this embodiment of the invention does not limit the specific connection method between the drawer 17 and the detergent dispenser 14. For example, the drawer 17 can be slidably connected to the detergent dispenser 14 in the first direction via a slide rail, or the drawer 17 can be movably connected to the detergent dispenser 14 in the first direction via a snap-fit ​​connection. Regardless of the connection method between the drawer 17 and the detergent dispenser 14, as long as the drawer 17 can move relative to the detergent dispenser 14 and open and close the opening 16, it is acceptable.

[0060] Among them, such as Figure 7 As shown, the first inlet 11 and the second inlet 12 are in the first direction ( Figure 7 (As shown by the arrow) on the same side of the drawer (both located on) Figure 7 (Right side of the middle). The outlet 13 can be located on the side of the mixing section 15 opposite to the second inlet 12. Of course, the outlet 13 does not necessarily have to be located in the first direction opposite to the second inlet 12. Figure 7 On the opposite end faces (in the direction of the arrow shown), Figure 7 In the illustrated embodiment, the water outlet 13 is located on the bottom surface of the mixing section 15, but the water outlet 13 is spaced a certain distance from the second water inlet 12. In this embodiment, water flows from the first water inlet along the first direction, forms a mixed liquid with the washing substance in the receiving cavity, and then flows back to the second water inlet. The water flowing in from the second water inlet then impacts the mixed liquid and moves it in the first direction, finally exiting through the water outlet. By setting the first water inlet and the second water inlet on the same side of the suction cup, and setting the water outlet opposite to the second water inlet, it is beneficial to extend the flow path of the mixed liquid in the cavity, further improving the mixing efficiency of water and disinfectant.

[0061] In some embodiments, such as Figure 7As shown, the mixing device further comprises a first water inlet pipe 2 and a second water inlet pipe 3. The first water inlet pipe 2 is connected to the first water inlet 11, and the first water inlet pipe 2 is used to guide water flow to the first water inlet 11. It should be noted that the shape and material of the first water inlet pipe 2 are not limited in the embodiment of the present application, as long as the first water inlet pipe 2 can guide water flow from a specified position to the first water inlet 11. One end 31 of the second water inlet pipe 3 in the embodiment of the present application is connected to the second water inlet 12, and the second water inlet pipe 3 is used to guide water flow to the second water inlet 12. It should be noted that the shape and material of the second water inlet pipe 3 are also not limited in the embodiment of the present application, as long as the second water inlet pipe 3 can guide water flow from a specified position to the second water inlet 12.
