The embodiment of the present invention provides a mixer, as shown in fig. 1-2, the mixer 2 being arranged in a dissolving device. The mixer 2 has a plurality of rotating blades 20, each rotating blade 20 is spirally disposed around a first direction (arrow direction shown in fig. 2), and it is to be noted that the rotating blades 20 are disposed in a spiral curve structure, that is, the rotating blades 20 are not only in a smooth curve structure, but also the rotating blades 20 are integrally provided with a torsion shape, so that when the mixed liquid with the washing substances flows through the surface of the rotating blades 20, the rotating blades are not required to rotate, the mixed liquid can twist along the surface of the rotating blades 20, the mixed liquid is influenced by the surface shape of the rotating blades 20, the flowing speed and direction of the mixed liquid passing through each point of the surface of the rotating blades 20 are changed, and a sharp inertia force is generated in the process of twisting the mixed liquid along with the surface structure of the rotating blades 20, so that the mixed liquid forms turbulence under the action of forces of different directions, and the liquid mixing and stirring are more sufficient.

It should be noted that the embodiment of the present invention is not limited to the specific structure of the rotary vane 20, and it is considered that the rotary vane 20 has a thin thickness and is a structure obtained by twisting a two-dimensional planar member. For example, a structure in which torque is applied to both ends of the rectangular thin plate member in the longitudinal direction (for example, clockwise torque is applied to one end and counterclockwise torque is applied to the other end) in opposite directions around the longitudinal direction, respectively, whereby the rotary vane forms approximately an X-shaped structure from a spatial perspective; of course, the rotor blade 20 may be formed by twisting a semicircular approximately planar member, and in other embodiments, the rotor blade 20 may be formed by twisting another shape, no matter what shape the rotor blade 20 is formed by twisting, so long as the liquid flowing along the rotor blade can twist and change the direction of the liquid.

As shown in fig. 2 and 3, the spiral directions of adjacent rotary blades 20 are opposite in the embodiment of the present invention. For example, in the process that the mixed liquid flows through the mixer 2, the movement direction of the mixed liquid is approximately consistent with the spiral direction of one of the rotating blades 20, when the mixed liquid moves from the rotating blade 20 to the adjacent rotating blade 20, the spiral direction of the adjacent rotating blade 20 is changed, so that the movement direction of the mixed liquid is changed, then the movement direction of the mixed liquid in the adjacent rotating blade 20 is approximately regarded as opposite to the movement direction of the rotating blade 20 (for example, the mixed liquid moves clockwise in the first direction in the rotating blade 20 and the mixed liquid moves anticlockwise in the first direction in the adjacent rotating blade 20), and the movement direction of the fluid is not the absolute opposite of the speed direction of the fluid at each point on the adjacent rotating blade, but it can be understood that the rotation direction of the fluid passing through the rotating blade is driven to deflect the rotation direction of the fluid to be opposite in the rotation direction on the two adjacent rotating blades due to the opposite spiral direction of the adjacent rotating blade. In some embodiments, the structure, length, and shape of each of the lobes may be different, so long as the spiral directions are opposite. In other embodiments, the structures of adjacent rotating blades may be identical, and it is understood that if each rotating blade can be disassembled into independent pieces, each rotating blade can be stacked and stacking surfaces are overlapped, and the rotating blade placement angles of the adjacent rotating blades with the same structure in the mixer are changed, it is understood that the phase positions corresponding to the starting edges of the adjacent rotating blades have angle differences. For example, in connection with fig. 3, fluid flows from the left side of the drawing to the right side through a plurality of lobes, and fig. 3 schematically shows three lobes which are identical in structure and shape, and in which an angle exists between the direction of extension of the starting edge (left edge) of the first lobe and the starting edge (left edge) of the second lobe as seen from left to right, so that when the fluid passes through the first lobe as seen from left to right, it rotates counterclockwise about the left-right direction shown in fig. 3, and when the fluid passes through the second lobe, it rotates clockwise about the left-right direction shown in fig. 3. No matter what specific expression form is adopted for the spiral directions of the two adjacent rotating blades to express opposite characteristics, the mixed liquid can twist in the movement direction when passing through the adjacent rotating blades.

Embodiments of the present invention provide a mixer having a plurality of lobes disposed helically about a first direction, adjacent lobes having opposite helical directions. In the process that the mixed liquid flows through the mixer, the mixed liquid moves along the spiral direction of the rotating blades, and as the movement speed and the movement direction of the mixed liquid at each point on the rotating blades are different, the mixed liquid positioned at the center and the outer edge of the rotating blades can collide with each other, the spiral direction of the adjacent rotating blades changes, and the mixed liquid can be reversed and exchanged under the action of the sharp inertia force, so that the washing substance can be fully mixed and dissolved with water under the action of the mixer, the disturbance effect of the mixed liquid is improved, the utilization rate of the washing substance is improved, and the consumption of the washing substance is reduced. And the above-described forward and reverse rotation of the mixed fluid as it passes through the rotary vane is not necessarily achieved by the rotation of the rotary vane.

In some embodiments, as shown in FIG. 3, adjacent edges of adjacent two of the lobes 20 extend in a perpendicular direction. The mixer 2 in the embodiment shown in fig. 3 is provided with a plurality of rotary vanes in a first direction (arrow direction shown in fig. 3), the adjacent rotary vanes 20 represent two rotary vanes closest to each other in the first direction among the plurality of rotary vanes 20, each rotary vane 20 has two ends in the first direction (arrow direction shown in fig. 3), one end (left end shown in fig. 3) is a first edge 201 of the rotary vane 20, the other end (right end shown in fig. 3) is a second edge 202 of the rotary vane 20, the first edge of each rotary vane is adjacent to the second edge of the other rotary vane, the second edge 202 of the rotary vane on the left side is adjacent to the first edge 201 of the rotary vane on the right side, and the extending direction (direction indicated by a broken line a in fig. 3) of the second edge 202 of the rotary vane on the left side is perpendicular to the extending direction (direction indicated by a broken line b in fig. 3), and it is required that the first edge or the second edge can be regarded as a plane, i.e. the extending direction of the first edge or the left edge is the extending direction of the first edge in the first direction (the broken line a) is the extending direction of the first edge b) of the first edge of the first direction, i.e. the maximum dimension of the figure is shown in the figure 3. In the embodiment of the invention, the second edge and the first edge of the adjacent rotating blades are basically vertical, and the extending direction of the second edge and the extending direction of the first edge are not strictly 90 degrees, so that the included angle between the two directions is considered to be more than 80 degrees, namely the included angle is basically vertical, and the conditions of processing and installation errors can be covered. Of course, in other embodiments, the extending directions of the adjacent edges of the adjacent two rotary vanes may be disposed at an acute angle, so long as the adjacent edges intersect.

The principle of stirring fluid by the mixer in the embodiment of the present invention will be described below with reference to fig. 4:

by extending the adjacent edges of two adjacent lobes, such as the second edge 202 of the first left hand lobe being substantially perpendicular to the first edge 201 of the second left hand lobe in fig. 4, the second edge of the second lobe is substantially perpendicular to the first edge of the third lobe, and when the mixed liquid flows from the first lobe to the second lobe, the liquid flowing to the second edge 202 of the first lobe forms two streams of liquid that flow along the sides of the second lobe, respectively, due to the first edge 201 of the second lobe being perpendicular to the second edge 202 of the first lobe, under the division of the first edge 201 of the second lobe. The solid arrow on the left side in fig. 4 indicates the mixed liquid flowing along the back surface of the first rotary vane, the dashed arrow indicates the mixed liquid flowing along the front surface of the first rotary vane, and the two liquids respectively flow along the front surface and the back surface of the first rotary vane, when the mixed liquid (indicated by the dashed arrow) flowing along the front surface of the first rotary vane flows to the second edge 202 of the first rotary vane, the mixed liquid on the front surface of the first rotary vane is divided into two liquids by the upper part of the first edge 201 of the second rotary vane, and the two liquids respectively flow along the two sides of the second rotary vane from the upper part; when the mixed liquid flowing on the back of the first rotary vane flows to the second edge 202 of the first rotary vane, the mixed liquid on the back of the first rotary vane is divided into two liquid flows by the lower part of the first edge 201 of the second rotary vane, and the two liquid flows along the two sides of the second rotary vane from the lower part respectively. Four liquid flows into the second rotating vane along different positions of the second rotating vane respectively, the four liquid flows mutually under the surface torsion action of the second rotating vane, and when flowing to the second edge 202 of the second rotating vane, each liquid is divided into two liquid by the first edge of the third rotating vane, and finally the four liquid is divided into 8 liquid by the third rotating vane. By vertically arranging the extending directions of the adjacent edges of the adjacent rotating blades, the adjacent rotating blades can continuously divide the mixed liquid, so that the efficiency of dissolving the washing substances in water can be enhanced; the mixed liquid can change the movement direction under the spiral direction of different rotary vanes, so that the liquid is subjected to the reverse rotation effect, the liquid can flow from the center to the outer edge or from the outer edge to the center in the process of flowing through the same rotary vane, the mixing effect of the washing substance and water is enhanced under multiple effects, and the dissolving efficiency of the washing substance is improved.

In some embodiments, as shown in fig. 3, each of the lobes 20 has opposing first and second edges 201, 202 in a first direction, the first edge 201 extending in a direction parallel to the second edge 202 extending. It should be noted that, in the embodiment of the present invention, the parallel direction indicates that the angle between the extending direction of the first edge 201 and the extending direction of the second edge 202 is not strictly 0 degrees, and it can be considered that the angle between the two directions is less than 10 degrees, i.e. the two directions are substantially parallel, so that the situations of machining and installation errors can be covered. According to the embodiment of the invention, the extending directions of the first edge and the second edge of each rotating blade in the first direction are parallel, so that the first edge rotates for one circle around the first direction and can coincide with the second edge after translating for a certain distance along the first direction, the mixed liquid moves along the spiral surface formed on the rotating blade, so that the mixed liquid originally below the rotating blade can move to the upper side of the rotating blade along with the surface of the rotating blade, the mixed liquid originally above the rotating blade can move to the lower side of the rotating blade, the liquid originally on the left side of the rotating blade can move to the right side of the rotating blade, the position of the liquid can be overturned by the spiral structure of the rotating blade, and the stirring efficiency of the mixed liquid is improved.

The embodiment of the invention also provides a dissolving device which can be applied to washing equipment such as clothes treatment equipment, dish washing equipment, fruit and vegetable cleaning equipment and the like.

The inner wall surface 33 of the drain pipe is substantially hollow and has an open end, and the circumferential direction is a direction around the longitudinal direction (a direction around an arrow in fig. 6). That is, a plurality of fins 34 are provided at intervals in the respective directions of the inner wall surface 33 to achieve sufficient disturbance of the mixed liquid flowing through the liquid discharge passage.

It should be noted that, in the embodiment of the present invention, the number of the fins 34 is closely related to the radial and length dimensions of the fins, and the disturbance effect of the fins 34 on the mixed liquid is not linearly increased with the number of the fins 34, and a plurality of fins are disposed in a drain pipe with a certain size, and as the number of the fins is increased, the disturbance effect of the fins on the mixed liquid may be increased or reduced. Therefore, the number of fins 34 provided also needs to be set according to the specific drain size.

In some embodiments, as shown in fig. 6, the distance L1 between adjacent fins 34 in the length direction of the drain channel 31 (the arrow direction shown in fig. 6) is greater than or equal to the first length, which is 0.8 times the inner diameter of the drain pipe 3, and less than or equal to the second length, which is 1.2 times the inner diameter of the drain pipe 3. It should be noted that, if the fins 34 have a plurality of points, the distances between the points of the adjacent fins 34 may not be uniform, and since one end of the fins 34 is connected to the inner wall surface 33 (the connection position may be regarded as a two-dimensional connection line), the distance between the adjacent fins 34 described in the embodiment of the present invention may be expressed as the shortest distance between the connection lines of the points of the adjacent fins 34. The distance between the fins is larger than the range value, so that a certain area exists between the fins to prevent the mixed liquid from being disturbed, the distance between the fins is lower than the range value, the blocking effect of the fins on the mixed liquid is too strong, the mixed liquid is difficult to flow through the gap between the fins, and the mixed liquid is difficult to form vortex to prevent disturbance. According to the embodiment of the invention, the distance between the adjacent fins in the length direction is set in a certain range, and the simulation analysis of the structural parameters shows that the fins in the data range have a good disturbance effect on the mixed liquid in the liquid discharge channel.

In some embodiments, as shown in fig. 6, the drain pipe 3 is provided with 3-5 fins at the same position in the length direction of the drain passage 31 (the direction indicated by the arrow shown in fig. 6). It is understood that a plurality of rows of fins 34 are provided in the longitudinal direction of the drain passage 31, each row of fins 34 is located on the same circumference, and a plurality of fins are provided in each row, and thus the fins 34 in the same row are considered to be located in the same position in the longitudinal direction. Simulation analysis shows that the liquid discharge pipe is provided with 3-5 fins, so that the disturbance effect of the liquid discharge pipe on the mixed liquid is good. It should be noted that, in other embodiments, other numbers of fins may be provided, that is, the number of fins may be related to the size of the drain pipe and the size of the fins.

In some embodiments, the fins adjacent in the length direction of the drain channel are staggered in the circumferential direction. That is, the projection intervals of the two adjacent rows of fins in the longitudinal direction are staggered in the circumferential direction, the fins are not overlapped with each other, and the positions of the two adjacent rows of fins in the longitudinal direction in the circumferential direction are different from each other. According to the embodiment of the invention, the stirring effect of the mixed liquid can be improved by staggering the fins. It should be noted that, the feature of staggered arrangement of the fins is not in a direct proportion to the stirring effect, and the stirring effect is related to parameters such as the number of the fins, the size of the drain pipe, etc., and the embodiment of the invention can select whether to set the feature of staggered arrangement of the fins according to the setting of other parameters, so that a stronger disturbance effect can be obtained.

In some embodiments, as shown in fig. 6, the included angle θ of the tangential plane at the connection between the fin 34 and the inner wall surface 33 is greater than or equal to 20 degrees and less than or equal to 45 degrees, one end of the fin 34 is connected to the inner wall surface 33, the other end is a free end, the end of the fin 34 connected to the inner wall surface 33 is a connection, and the tangential plane at the connection is perpendicular to the radial direction of the liquid discharge tube 3. The fin 34 may be approximately a two-dimensional planar member, and the angle between the fin 34 and the inner wall surface may be approximately the angle between the two-dimensional planar member and the tangent plane at the junction, i.e., the angle between the two planes. The angle θ of the tangential plane at the junction of the fin 34 and the inner wall surface 33 indicates the angle of the fin 34 from the tangential plane, not from the left side surface in fig. 6. The distance from the fin 34 to the inner wall surface 33 increases as it goes away from the inlet 32 of the drain passage 31, and it is understood that the distance from the fin 34 to the inner wall surface 33 gradually increases from left to right in fig. 6. According to the embodiment of the invention, the fins are obliquely arranged relative to the inner wall surface, so that the fins can play a disturbing role on the mixed liquid in the liquid discharge channel, and the mixed liquid cannot be remained between the fins and the inner wall surface.

In some embodiments, as shown in fig. 7, one end 341 of the fin 34 in the length direction is connected to the inner wall surface 33, and the length direction indicates the extending direction of the fin 34 (this direction is not necessarily the direction of the maximum dimension of the fin 34), that is, the direction from one end 341 to the other end 342 of the fin 34, and the other end 342 of the fin 34 is a free end; the width of the tab 34 gradually decreases from one end to the other. The width direction of the fin 34 is perpendicular to the length direction. By setting the width of the fin to be gradually reduced from one end to the other end, the speed and the direction of the mixed liquid flowing through each point of the fin are changed, the mixed liquid is easier to form turbulence under the condition of changing the size of the fin, and the disturbance effect of the mixed liquid is improved.

In some embodiments, as shown in fig. 7, a width L3 of one end 341 of the fin 34 is greater than or equal to 0.08 times an inner diameter L2 of the drain 3 and less than or equal to 0.12 times the inner diameter L2 of the drain 3; in the case where the drain pipe 3 is provided as a standard round pipe, the inside diameter of the drain pipe 3 may be represented by the inside diameter of the drain pipe 3; when the drain pipe 3 is provided in a non-standard shape, the cross section of the drain pipe 3 may be converted into a standard circular surface of equal area, and the diameter of the standard circular surface may be defined as the inner diameter of the drain pipe 3, wherein the cross section of the drain pipe 3 is perpendicular to the longitudinal direction of the drain pipe 3. In some embodiments, the width L4 of the other end 342 of the tab 34 is greater than or equal to 0.2 times the inner diameter L2 of the drain 3 and less than or equal to 0.25 times the inner diameter L2 of the drain 3; in some embodiments, the length L5 from one end 341 of the fin 34 to the other end 342 is greater than or equal to 0.4 times the inner diameter L2 of the drain 3 and less than or equal to 0.45 times the inner diameter L2 of the drain 3. The size of the wing provided by the embodiment of the invention is obtained through simulation analysis, and the wing with the size can provide a higher-efficiency stirring effect.

The embodiment of the invention also provides a clothes treatment device, which comprises the dissolving device and the barrel body according to any one of the embodiments, wherein a washing cavity is arranged in the barrel body and is communicated with a containing cavity of the dissolving device, specifically, an outlet of the dissolving device can be communicated to the washing cavity, mixed liquid stirred by a mixer in the dissolving device flows into the washing cavity through the outlet, clothes in the washing cavity are contacted and rubbed with the mixed liquid, and as the washing substance stirred by the dissolving device is fully mixed and stirred with water, the washing substance is fully dissolved in the water to form the mixed liquid, and the mixed liquid after stirring forms a certain foam, so that the clothes cleaning degree in the washing cavity is improved.
