The present invention is primarily directed to an oscillating fluidic device 100, primarily for use in a household washing appliance 500, such as a dishwasher, by providing the oscillating fluidic device 100 with an oscillating chamber 130 in the middle and feedback loops 140 on both sides, and at the same time by setting the width of the oscillating chamber 130, the width and the diverging angle of the fluid outlet 120 of the oscillating fluidic device 100 and the relationship between the parameters to increase the area covered by the oscillating jet ejected from the fluid outlet 120 and to improve the uniformity of the oscillating jet;
by setting the width d of the fluid inlet 110, the width f and the divergent angle b of the inlet of the oscillation cavity 130, the width W and the length H of the oscillation cavity 130, the width e and the divergent angle c of the fluid outlet 120 and the proportional relation among all the parameters, the energy loss of the fluid in the oscillation cavity 130 is smaller, so that the structural vibration of the whole device caused by the oscillation jet is reduced, and the jet is more stable in the oscillation process;
by providing the feedback loop 140 in a fully or partially arcuate shape and defining the relationship between the widths m, n, l of the feedback loop 140, and the relationship between l and the width W of the oscillator chamber 130, the flow of fluid in the feedback loop 140 is made more flow-field, reducing the risk of particulate matter in the fluid accumulating in the loop and blocking the flow path.
Therefore, the cleaning efficiency and the cleaning stability of the cleaning equipment are improved. It is worth noting that the oscillating fluidic device 100 is very flexible in its application, for example, by being mounted on the spray arm 200, the spray arm 200 is rotated or moved so that the spray arm 200 can form a large, stable, and efficient washing area; of course, in some embodiments, the oscillating jet device may be fixedly mounted directly on the bottom, the top or the side wall of the washing chamber of the washing apparatus.
The specific structure of the oscillating jet device 100 will be mainly described below.
Referring to fig. 1-5, in an embodiment of the present invention, the oscillating fluidic device 100 includes a housing having a fluid inlet 110, a fluid outlet 120, and an oscillation chamber 130 and a feedback loop 140 located between the fluid inlet 110 and the fluid outlet 120;
the ratio of the length H to the width W of the oscillation cavity 130 is 1.5-2;
the ratio of the width d to the width W of the fluid inlet 110, d/W, is 0.35-0.55.
Specifically, in the present embodiment, the oscillation chamber 130 is located in the middle of the housing, the feedback loop 140 is located at two opposite sides of the oscillation chamber 130, the fluid inlet 110 is located at one end of the housing, and the fluid outlet 120 is located at the other end of the housing. Wherein the inlet 141 of the feedback loop 140 is between the fluid inlet 110 and the inlet of the oscillator chamber 130 and the outlet 142 of the feedback loop 140 is between the outlet 132 of the oscillator chamber 130 and the fluid outlet 120. Wherein the fluid comprises one of gas, liquid and gas-liquid mixture. When fluid enters from the fluid inlet 110, the fluid enters the oscillation cavity 130 and is deflected to the side wall on one side due to the coanda effect, and then part of the fluid enters the feedback loop 140, so that the left and right feedback loops 140 generate pressure difference on two sides of the inlet fluid to push the fluid to the side wall on the other side, and the process is repeated in a circulating way.
In the embodiment, the ratio H/W of the length H to the width W of the oscillation cavity 130 is set to be 1.5-2, and the ratio d/W of the width d to the width W of the fluid inlet 110 is set to be 0.35-0.55, so that the ratio of H/W to d/W is moderate, the phenomenon that the oscillation effect of the oscillation cavity 130 is not good, even the oscillation cannot be generated is avoided, meanwhile, the ratio between the length H and the width W of the oscillation cavity 130 and the width d of the fluid inlet 110 is very coordinated, the vibration of the fluid in the oscillation cavity 130 is greatly reduced, the phenomenon that the intermittent oscillation occurs is avoided, the oscillation is stable, the energy loss of the fluid in the injection process is effectively reduced, and the injection distance and the injection stability of the oscillation fluidic device 100 are greatly improved.
Of course, in other embodiments, to further improve the stability of the oscillating fluidic device 100, the ratio of the width d of the fluid inlet 110 to the width f of the inlet 131 of the oscillating cavity 130, d/f, is 0.8-1.2. By setting the relationship between the width d of the fluid inlet 110 and the width f of the inlet 131 of the oscillation chamber 130, the ratio between the length H and the width W of the oscillation chamber 130, the width f of the inlet 131 of the oscillation chamber 130 and the width d of the fluid inlet 110 is further defined, so that the relative dimensions of the structure of the oscillation chamber 130 are more consistent and the stability is more reliable.
In order to further increase the area covered by the fluid when the fluid is ejected from the outlet, the ratio of the width e of the fluid outlet 120 to the width d of the fluid inlet 110, e/d, is 0.7-1.3. By setting the proportional relationship between the width e of the fluid outlet 120 and the width d of the fluid inlet 110, and by combining the ratio d/W relationship between the width d and the width W of the fluid inlet 110, the width range of the fluid outlet 120 is defined, so that the oscillating jet can be swung open very well, which is beneficial to greatly increase the area covered by the fluid outlet 120.
In some embodiments, in order to increase the fluency of the feedback loops 140, the number of the feedback loops 140 is two, two feedback loops 140 are respectively located at two opposite sides of the oscillation cavity 130, and part or all of the feedback loops 140 are arranged in a convex arc protruding away from the oscillation cavity 130.
In this embodiment, the feedback loops 140 on both sides of the oscillation chamber 130 are disposed in a circular arc shape, but in some embodiments, the feedback loops may also be partially in a circular arc shape, and partially in a linear shape tangential to the circular arc shape. The oscillator chamber 130 and the feedback loop 140 are separated by two island structures. By providing the feedback loop 140 with a convex arc structure, the fluid encounters less resistance when passing through the feedback loop 140, which is beneficial to improving the fluency of the fluid in the feedback loop 140.
Meanwhile, in some embodiments, in order to further improve the fluency and the stability of the fluid in the feedback loop 140, the ratio l/W between the width l of the feedback loop 140 and the width W of the oscillation cavity 130 is 0.2-0.4. The feedback loop 140 is too wide, which easily causes an increase in energy loss during the fluid flow process, and has a low energy efficiency ratio, and when the feedback loop 140 is too narrow, the feedback is not effective enough, which may cause a risk of blockage. After the ratio l/W is set to be 0.2-0.4, the width of the feedback loop 140 is related to the width of the oscillation cavity 130, and the width is ensured to be in a proper range.
It should be noted that, in some embodiments, the widths of the entire feedback loops 140 are different, the width of the inlet 141 of the feedback loop 140 is m, the width of the outlet 142 of the feedback loop 140 is n, and the width of the middle portion is l, where m and n are greater than or equal to l, and the ratio m/W is set to 0.2-0.4, and the ratio n/W is set to 0.2-0.4. By such an arrangement, the fluency of the fluid in the entire feedback loop 140 is ensured, thereby effectively improving the fluency and stability of the oscillating fluidic device 100.
In order to further improve the stability and fluency of the oscillating fluidic device 100 and increase the coverage of the jet, the fluid inlet 110 is arranged to be gradually expanded from the direction close to the oscillating cavity 130 to the direction far away from the oscillating cavity 130, and the gradually expanded angle a of the side wall of the fluid inlet 110 is 10-30 °. Through the arrangement of a, the pressure of the fluid is effectively increased when the fluid enters the oscillation cavity 130, and the entering flow rate is increased. When a is too small, the increased pressure is too small to meet the requirement, and when a is too large, the excessive pressure is difficult to coordinate with other parameters, so that the overall coordination is not facilitated.
In order to ensure the oscillation effect, the side wall of the oscillation cavity 130 has a first flow guide part 133, the first flow guide part 133 is arranged in a gradually expanding manner from the inlet to the inside of the oscillation cavity 130, and the gradually expanding angle b is 30-70 degrees. After the fluid enters the oscillation cavity 130, the fluid flows along the first flow guide part 133 right and left below the first flow guide part 133, the pressure is firstly gradually reduced in the flowing process, and when the width of the oscillation cavity 130 is not changed any more, the pressure is not changed any more. The value of b should not be too large, nor too small, and too large or too large will make the oscillation effect poor, even difficult. In some embodiments, the combination of the first flow guiding part 133 and the vertical side wall may be replaced by providing the side wall of the oscillation cavity 130 with a concave arc surface, and a good oscillation effect may be achieved.
In some embodiments, in order to further adjust the oscillation effect, the side wall of the oscillation cavity 130 has a second flow guiding portion 134, and the second flow guiding portion 134 is arranged in a divergent manner from the end of the first flow guiding portion 133 to the outlet 132 of the oscillation cavity 130, and the divergent angle q is 0-15 °. Under the effect of the second flow guide part 134, the fluid is facilitated to further flow along the second flow guide part 134, so that the fluidity of the fluid in the oscillation cavity 130 is effectively improved, and the oscillation effect is ensured.
In order to further improve the oscillation stability and increase the range covered by the fluid ejected from the fluid outlet 120, the fluid outlet 120 is gradually expanded from the end close to the oscillation cavity 130 to the end far away from the oscillation cavity 130, and the gradually expanded angle c of the fluid outlet 120 is 20-60 °. By limiting c to 20 deg. -60 deg., when considered together with the width e of the fluid outlet 120, the length of the fluid outlet 120 is defined so that the oscillating jet can be swung open very well, which is advantageous for substantially increasing the area covered by the fluid from the fluid outlet 120. I.e. when c, e are taken together, both jet outlet oscillation angles p can be effectively increased. Namely, when the width of the outlet e is increased, the swing angle p of the jet outlet can be effectively increased; when the gradually widening angle c of the outlet is increased, the swinging angle p of the jet outlet can be effectively increased.

Referring to fig. 11-21, a spray device that may be used with the oscillating jet device 100 of the above embodiment is described further below.
A spray rinsing device comprising:
the spray arm 200 is provided with a water inlet 210, a plurality of water outlets 220 arranged along the length direction of the spray arm 200, and a flow channel for communicating the water inlet 210 with the water outlets 220;
the oscillating jet flow nozzle 100 is arranged in the water outlet hole 220, and the oscillating jet flow nozzle 100 is arranged in the water outlet hole 220;
the oscillating jet flow nozzle 100 forms a spray area in the spray direction of the spray arm along with the rotation of the spray arm, a first spray area and a second spray area of the two oscillating jet flow nozzles 100 respectively have a first projection and a second projection in a first plane, and the first projection and the second projection are intersected. Wherein the first plane is perpendicular to the jetting direction of the oscillating jet nozzle.
Specifically, in the present embodiment, the spray arm 200 is disposed in a strip shape, and the water inlet 210 is disposed at a plurality of positions, for example, at the bottom of the spray arm 200. The positions and the number of the water outlet holes 220 can be set according to requirements, and when the spray washing device is only required to spray upwards, the water outlet holes 220 can be formed only at the top of the spray arm 200; when the top of the spray arm 200 is required to be sprayed and cleaned, and the bottom of the spray arm 200 is required to be sprayed and cleaned, the water outlet holes 220 are formed in the top and the bottom of the spray arm 200 at the same time. The outlet holes 220 are arranged along the length direction of the spray arm 200. In some embodiments, the oscillating jet nozzle 100 is arranged in a straight line along the length of the spray arm 200.
The water surface sprayed by each oscillating jet nozzle 100 is a vertical surface formed by the water flow swinging from the nozzle to the spraying direction, and the water surface sprayed by each oscillating jet nozzle 100 is arranged in a triangle when viewed from the side. When the nozzle sprays in the vertical plane, the sprayed water surface is triangular, and the projection of the cleaning area capable of being swept by the nozzle in the horizontal plane is a straight line. If the nozzle is disposed at an angle to the vertical, the projection of the water surface ejected from the oscillating jet nozzle 100 on the horizontal plane is a plane.
It is worth noting that, with reference to fig. 21, in some embodiments, there may be a relative rotation between the oscillating jet nozzle and the spray arm, i.e. the oscillating jet nozzle has an axis of rotation about which it spins. At this time, the rotation axis may be perpendicular to the spray arm; in some embodiments, in order to meet the requirements of special working conditions, the rotating axis can be arranged to form an included angle with the spray arm. When the nozzle rotates around the rotation axis, a conical spraying area is formed, and the conical spraying area moves along with the rotation of the spray arm to form an annular spraying area with a triangular cross section. Through making the rotation of oscillating jet nozzle for each position in the spray rinsing region all receives multiple impact (the rotation of nozzle is washed and the nozzle is washed along with the repetition after the spray arm rotates), is favorable to improving the washing effect by a wide margin.
The oscillating jet nozzle 100 is described below as emitting in a vertical plane, which may refer not only to the vertical plane in which the plurality of nozzles are located, but also to a vertical plane perpendicular to the plane in which the spray arm 200 is located. At this time, the vertical water surface sprayed by the oscillating jet nozzle 100 may be parallel to the spray arm 200, may be disposed at an included angle with the spray arm 200, and may be perpendicular to the spray arm 200. When the oscillating jet nozzle 100 is ejected as the spray arm 200 rotates, the oscillating jet nozzle 100 forms a circular spray area. If the first projection and the second projection of the water surface ejected by the oscillating jet nozzle 100 on the first plane (taking a horizontal plane as an example) intersect (when the projection is a straight line, it means that the two straight lines intersect; when the projection is a plane, it means that the two planes intersect), it means that the water outlet surfaces ejected by the adjacent nozzles (corresponding to the spraying area in the above-mentioned embodiment, specifically, the cleaning plane) spatially intersect, so as to ensure that the cleaning plane N ejected by the plurality of nozzles is a continuous and uninterrupted cleaning plane M during the rotation of the spray arm 200.
In this embodiment, through set up rivers passageway and a plurality of apopores 220 with rivers passageway intercommunication on spray arm 200 at the belt cleaning device of dish washer, each apopore 220 is connected with an oscillation jet nozzle 100, oscillation jet nozzle 100 is along with spray arm 200 pivoted in-process, form annular spray rinsing region, spray rinsing region is three-dimensional form setting, including the washing plane that is located spray rinsing region top and the connection face that is located between nozzle 100 export and the washing plane, this connection face is being sprayed to the washing plane and is forming along with spray arm 200's rotation in-process by rivers. Taking the oscillating jet nozzle 100 to vertically spray upwards and the spray arm 200 to complete circumferential rotation as an example, at this time, the cleaning plane is located right above the oscillating jet nozzle 100 and is arranged annularly, and at this time, if the two cleaning planes are located in the same horizontal plane, the two cleaning planes are intersected; if the two cleaning planes are different, the projections of the two cleaning planes in the first plane intersect, wherein the first plane is perpendicular to the jetting direction of the oscillating jet nozzle 100, that is, the cleaning planes of the jetting area intersect to form a continuous cleaning plane in the jetting direction of the nozzle 100. It should be noted that, in general, the projection in the first plane, the projection of the cleaning plane covers the projection of the connecting surface, that is, the intersection of the first projection and the second projection of the first spray area and the second spray area in the first plane, means the intersection of the projection of the first cleaning plane corresponding to the first spray area and the projection of the second cleaning plane corresponding to the second spray area. Therefore, when the spray arm 200 rotates, the areas cleaned by the two oscillating jet nozzles 100 are partially overlapped, so that the areas cleaned by the oscillating jet nozzles 100 are continuous and uninterrupted, and the cleaning device of the cleaning equipment can clean dishes and other tableware in the cleaning basket of the dish washer in an all-around and dead-angle-free manner, thereby improving the cleaning effect of the cleaning device of the dish washer.
In order to improve the cleaning efficiency of the cleaning device and ensure that the cleaning area generated by the rotation of the spray arm 200 is a continuous and uninterrupted cleaning surface, the first spray area and the second spray area intersect, and the corresponding intersection of the first cleaning plane and the second cleaning plane is taken as an example.
In some embodiments, in order to improve the cleaning efficiency of the cleaning apparatus, the oscillating jet nozzles 100 are linearly disposed at the top and/or bottom of the spray arm 200 in order to improve the utilization of each oscillating jet nozzle 100 by reducing the number of the oscillating jet nozzles 100. That is, the oscillating jet nozzle 100 is disposed on the top of the spray arm 200, or on the bottom of the spray arm 200, or on both the top and bottom of the spray arm 200. The oscillating jet nozzles are utilized to the maximum extent by being arranged on the same straight line and by arranging the projection of the spray area of each oscillating jet nozzle 100 in the horizontal plane to be a straight line parallel to the spray arm 200. Of course, in other embodiments, the oscillating jet nozzles 100 may be arranged in different, desired shapes instead of straight lines, and the linearity includes not only straight lines but also curves extending according to a predetermined rule.
In order to improve the spray efficiency of the oscillating jet nozzle and arrange the oscillating jet nozzle sufficiently and reasonably to improve the space utilization rate and meet different working condition requirements, the arrangement condition of the oscillating jet nozzle on the spray arm is described below.
The shapes of the spray arms can be various, and only the continuous cleaning planes corresponding to the two oscillating jet nozzles need to be met. The following description will be made by taking a straight spray arm (see fig. 11 to 13, with the rotation axis of the spray arm as a reference, two spray arm segments 240 on the same straight line), a three-forked spray arm (see fig. 17 to 18, with the rotation axis of the spray arm as a reference, three spray arm segments 240 radially arranged around the rotation axis) and a cross spray arm (see fig. 19 and 20) as examples. Of course, the spray arm segments 240 can also be five, six or even more.
More specifically, regarding the arrangement of the nozzles, a plurality of circular rings are formed by taking the rotating axis of the spray arm as a circle center line and taking the distance between the oscillating jet nozzle and the circle center line as a radius; each ring is provided with at least one oscillating jet nozzle, and the oscillating jet nozzles can be arranged at any position on the rings. The distance between the adjacent circular rings is related to the coverage range of a cleaning plane of a spray washing area of the oscillating jet nozzle, the larger the coverage range, the larger the distance between the adjacent circular rings can be, and the smaller the distance can be otherwise. At least one nozzle is arranged on different circular rings, and the nozzle can be arranged at any position of the circular rings, because the nozzle on each circular ring can form a circular cleaning plane in the rotating process of the spray arm.
Referring to fig. 11 to 13, when the two oscillating jet nozzles are located on the same side of the rotation axis of the spray arm, the two oscillating jet nozzles are adjacent to each other. That is, when the oscillating jet nozzles are located on the same boom section 240, the two oscillating jet nozzles are located adjacent to each other.
When two of the oscillating jet nozzles are located on either side of the arm axis of rotation, i.e., when the oscillating jet nozzles are located on symmetrical arm segments 240, one of the oscillating jet nozzles is adjacent to a mapping position where the other oscillating jet nozzle is symmetrical about the arm axis of rotation.
It should be noted that when the spray arm includes two spray arm segments 240 arranged about the rotation axis, the included angle between the two spray arm segments 240 may be different from 180 °, or may be, for example, 120 °, 170 °, or the like. Of course, in some embodiments, all nozzles may be arranged on different arm segments 240 of the arm, or may be arranged only on the same arm segment 240.
Referring to fig. 17-18, one end of each of three spraying arm sections 240 is connected to the rotation axis, the other end of each of the three spraying arm sections 240 extends in a direction away from the rotation axis, and every two of the three spraying arm sections 240 form an included angle of 120 degrees. Of course, in some embodiments, the angle between each two can be adjusted according to more practical requirements, such as 100 °, 160 °, and so on.
The cross-shaped spray arm, referring to fig. 19-20, includes four spray arm sections 240, and is pairwise symmetrical, that is, an included angle between two adjacent spray arm sections 240 is 90 °, and of course, in some embodiments, the included angle between two adjacent spray arm sections 240 may be adjusted according to actual needs.
In order to rotate the spray arm 200, a driving means such as a motor may be provided to rotate the spray arm 200, or a reaction force at the time of water spraying may be used. Specifically, the spray device further includes a driving nozzle 230, the driving nozzle 230 is disposed at the side portions of the two ends of the spray arm 200 to drive the spray arm 200 to rotate, and the cleaning region of the oscillating jet nozzle 100 disposed at the top and/or the bottom of the spray arm 200 forms a cleaning ring surface along with the rotation of the spray arm 200. The driving nozzles 230 are disposed at opposite sides, i.e., diagonal positions, of both ends of the spray arm 200 so that reaction forces applied to the spray arm 200 by the driving nozzles 230 of both ends are reversed to drive the spray arm 200 to rotate.
The positional relationship between the adjacent nozzles is not limited to this embodiment, but may be applied to other embodiments, particularly, the same for the case where the nozzle arm does not rotate, even without the nozzle arm.

2h1tan(α12) ((1 + 15%) or 2h2tan(α2/2)*(1+15％)
By setting the distance between two adjacent oscillating jet nozzles 100 in this way, the cleaning planes of adjacent spray cleaning areas are ensured to be intersected, so that 360-degree dead-angle-free spray cleaning during rotation of the spray arm 200 is effectively ensured.
Wherein, the movement of the water is influenced by the nozzle structure within a certain range after leaving the nozzle, a radiation area of the nozzle is formed within a certain range, namely within the radiation area, the coverage of the water flow is controlled by the nozzle; after the water flow leaves the radiation area, because the water flow still has a motion state (kinetic energy, potential energy and the like), collision between the water flows and sputtering of the water flow can occur in the continuous motion process of the water flow, and in the area, due to a plurality of influencing factors, the coverage area of the water flow is not completely controlled by the nozzle, and the area is a sputtering area.
The following is an example of a specific irradiation region and sputtering region range, using the above formula as an example:
the width of the first radiation region is 2h1tan(α1/2) the width of the first sputtering zone is less than or equal to h1tan(α1/2) 15%; the width of the second radiation region is 2h2tan(α2/2) the width of the second sputtering zone is less than or equal to h2tan(α2/2)*15％。

In other embodiments, this may be defined and calculated in different ways, as follows:
the first spray area comprises a first cleaning plane parallel to the first plane, and the second spray area comprises a second cleaning plane parallel to the first plane; the parallel state includes a parallel state, and the deviation from the parallel state is allowed within a certain range, so that the states of the first cleaning plane and the second cleaning plane can contain specific working condition requirements, that is, under the influence of actual working condition conditions, the position relationship between the cleaning planes and the first plane still satisfies the parallel relationship.
The spray angles of the two oscillating jet nozzles are α respectively1And α2(ii) a The distances between the water outlets of the two oscillating jet nozzles and the first cleaning plane and the second cleaning plane are h respectively1And h2；

2h1tan(α12) ((1 + 15%) or 2h2tan(α2/2)*(1+15％)
It should be noted that, when the distance between the two oscillating jet nozzles without the rotation of the nozzle arm or without the nozzle arm is calculated in this way, "the distance between the oscillating jet nozzle and the rotation axis of the nozzle arm is taken as a radius, and the difference between the radii of the circumferences where the two oscillating jet nozzles are located is greater than 0 and less than or equal to" instead "the distance between two adjacent oscillating jet nozzles is greater than 0 and less than or equal to", that is, the distance between two adjacent oscillating jet nozzles can be directly calculated according to the above parameters.
Wherein, the movement of the water is influenced by the nozzle structure within a certain range after leaving the nozzle, a radiation area of the nozzle is formed within a certain range, namely within the radiation area, the coverage of the water flow is controlled by the nozzle; after the water flow leaves the radiation area, because the water flow still has a motion state (kinetic energy, potential energy and the like), collision between the water flows and sputtering of the water flow can occur in the continuous motion process of the water flow, and in the area, due to a plurality of influencing factors, the coverage area of the water flow is not completely controlled by the nozzle, and the area is a sputtering area.

In order to further improve the cleaning precision, the distance between two adjacent oscillating jet nozzles 100 is gradually decreased from the water inlet 210 to a direction away from the water inlet 210. As water is sprayed from the nozzles, the water pressure of the nozzles far from the water inlet 210 is less than the water pressure of the nozzles near the water inlet 210, so that the spraying range and height of the nozzles with different distances from the water inlet 210 are different. The distance between the nozzles is adjusted in order to minimize the influence of the water pressure on the nozzle spray. The distance between the nozzles far from the water inlet hole 210 is shortened to ensure that the cleaning areas sprayed by two adjacent oscillating jet nozzles 100 are spatially connected to ensure the continuity of the cleaning areas formed by the rotation of the spray arm 200.
