The present invention mainly proposes an oscillating-jet device 100, mainly applied to a household washing apparatus 500, such as a dishwasher, by providing the oscillating-jet device 100 with an oscillating chamber 130 at the middle and feedback loops 140 at both sides, and at the same time, by providing the relationship between the width of the oscillating chamber 130, the width of the fluid outlet 120 of the oscillating-jet device 100 and the parameters of the diverging angle and 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 diverging angle b of the inlet of the oscillating cavity 130, the width W and the length H of the oscillating cavity 130, the width e and the diverging angle c of the fluid outlet 120 and the proportional relation among the parameters, the energy loss of the fluid in the oscillating cavity 130 is smaller, so that the structural vibration of the whole device caused by the oscillating jet flow is reduced, and the jet flow is more stable in the process of oscillation;
by arranging the feedback loop 140 entirely or partly in an arc shape and defining the relation between the widths m, n, l of the feedback loop 140 and the relation between l and the width W of the oscillation cavity 130, the flow of fluid in the feedback loop 140 is made more flow-field, reducing the risk that particles that may be present in the fluid accumulate in the loop and block the flow channel.
Thus, the cleaning efficiency and the cleaning stability of the cleaning equipment are improved. It should be noted that the oscillating jet device 100 is very flexible in application, for example, it is mounted on the spray arm 200, and the spray arm 200 rotates or moves so that the spray arm 200 can form a wide, stable and efficient flushing area; of course, in some embodiments, the oscillating jet device may also be fixedly mounted directly on the bottom, top or side wall of the cleaning chamber of the cleaning apparatus.
The specific structure of the oscillating fluidic 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 oscillating cavity 130 and a feedback loop 140 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 W of the fluid inlet 110, d/W, is 0.35 to 0.55.
Specifically, in the present embodiment, the oscillation cavity 130 is located in the middle of the housing, the feedback loop 140 is located on two opposite sides of the oscillation cavity 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 inflow 141 of the feedback loop 140 is between the fluid inlet 110 and the inlet of the oscillation cavity 130, and the outflow 142 of the feedback loop 140 is between the outlet 132 of the oscillation cavity 130 and the fluid outlet 120. Wherein the fluid comprises one of a gas, a liquid, and a mixture of a gas and a liquid. When fluid enters from the fluid inlet 110, the fluid enters the oscillating cavity 130 and is deflected to one side wall 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 a pressure difference on two sides of the inlet fluid, and the fluid is pushed to the other side wall, and the circulation is repeated.
In this embodiment, the ratio H/W of the length H to the width W of the oscillation cavity 130 is set to 1.5-2, and the ratio d/W of the width d to the width W of the fluid inlet 110 is set to 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 poor, or even the oscillation cannot occur is avoided, meanwhile, the ratio of the length H, 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 of intermittent oscillation 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 jet device 100 are greatly improved.
Of course, in other embodiments, to further enhance 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 relation between the width d of the fluid inlet 110 and the width f of the inlet 131 of the oscillating cavity 130, the length H, the width W of the oscillating cavity 130, the ratio between the width f of the inlet 131 of the oscillating cavity 130 and the width d of the fluid inlet 110 are further defined, so that the relevant dimensions of the structure of the oscillating cavity 130 are more coordinated and the stability is more reliable.
In order to further increase the area covered by the fluid when it 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 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 relationship between the ratio d/W of the width d of the fluid inlet 110 and the width W, the width range of the fluid outlet 120 is defined, so that the oscillating jet can swing very well, which is beneficial to greatly improving the area covered by the fluid from the fluid outlet 120.
In some embodiments, in order to increase the smoothness of the feedback loops 140, the number of feedback loops 140 is two, and the 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 disposed in a convex arc protruding in a direction away from the oscillation cavity 130.
In this embodiment, the feedback loops 140 on both sides of the oscillating cavity 130 are disposed in a circular arc shape, and of course, in some embodiments, the feedback loops may be partially in a circular arc shape and partially in a straight line tangent to the circular arc shape. The oscillation cavity 130 and the feedback loop 140 are separated by two island structures. By configuring feedback loop 140 as a convex arc, less resistance is encountered by the fluid as it passes through feedback loop 140, which is beneficial to improving the fluency of the fluid in feedback loop 140.
Meanwhile, in some embodiments, in order to further improve the smoothness and stability of the fluid in the feedback loop 140, the ratio of the width l of the feedback loop 140 to the width W of the oscillation cavity 130 is 0.2 to 0.4. The feedback loop 140 is too wide, which tends to increase energy loss during fluid flow, and the energy efficiency ratio is low, and when the feedback loop 140 is too narrow, the feedback is not effective enough, with the risk of clogging. After setting the ratio l/W to 0.2-0.4, the width of the feedback loop 140 is correlated with the width of the oscillation cavity 130, ensuring that the width is within a proper range.
It should be noted that, in some embodiments, the width of the feedback loop 140 is not the same, 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, the width of the middle is l, where the values of m and n are greater than or equal to l, the ratio m/W is set to 0.2-0.4, and the ratio n/W is set to 0.2-0.4. By doing so, the fluency of the fluid in the entire feedback loop 140 is ensured, thereby effectively improving the fluency and stability of the oscillating jet device 100.
In order to further improve the stability and smoothness of the oscillating jet device 100 and increase the coverage of the injection, the fluid inlet 110 is gradually widened from the direction close to the oscillating cavity 130 to the direction away from the oscillating cavity 130, and the gradually widened angle a of the side wall of the fluid inlet 110 is 10 ° to 30 °. By the arrangement of a, the fluid pressure is effectively increased when entering 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 pressure is too large to be coordinated 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 guiding portion 133, where the first guiding portion 133 is gradually widened from the inlet to the inside of the oscillation cavity 130, and the gradually widened angle b is 30 ° to 70 °. After the fluid enters the oscillating cavity 130, the fluid flows along the first diversion part 133 at the left and right lower sides of the first diversion part 133, the pressure is firstly gradually reduced in the flowing process, and when the width of the oscillating cavity 130 is not changed any more, the pressure is not changed any more. The value of b is not too large or too small, and too large or large will make the oscillation effect poor or even difficult. In some embodiments, the side wall of the oscillating cavity 130 may be a concave arc surface instead of the combination of the first diversion portion 133 and the vertical side wall, so that a good oscillating effect may be achieved.
In some embodiments, to further adjust the oscillation effect, the side wall of the oscillation cavity 130 has a second guiding portion 134, where the second guiding portion 134 is gradually widened from the end of the first guiding portion 133 to the outlet 132 of the oscillation cavity 130, and the gradually widened angle q is 0 ° to 15 °. Under the action of the second flow guiding part 134, the fluid is favorable to further flow along the second flow guiding part 134, so that the fluidity of the fluid in the oscillating cavity 130 is effectively improved, and the oscillating 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 widened from the end close to the oscillation cavity 130 to the end far from the oscillation cavity 130, and the gradually widened angle c of the fluid outlet 120 is 20 ° to 60 °. By limiting c to 20 deg. to 60 deg., when considered in conjunction with the width e of the fluid outlet 120, the length of the fluid outlet 120 is defined such that the oscillating jet can swing very well open, facilitating a substantial increase in the area covered by fluid from the fluid outlet 120. Namely, when c and e are comprehensively considered, the swing angle p of the jet outlet can be effectively increased. That is, when the width of the outlet e is increased, the swing angle p of the jet outlet can be effectively increased; when the outlet widening angle c is increased, the swing angle p of the jet outlet can be effectively increased.
The present invention also proposes a household cleaning apparatus 500, where the household cleaning apparatus 500 includes a liner and an oscillating jet device 100, and the specific structure of the oscillating jet device 100 refers to the above embodiment, and since the household cleaning apparatus 500 adopts all the technical solutions of all the embodiments, at least has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

With respect to the specific structure of the base 600, there may be various kinds of structures, such as being divided into multiple layers, each layer corresponding to one or more sub-channels 617, and of course, all the sub-channels 617 may be located in the same layer. The flow channel 612 may be formed in various ways, such as by forming grooves, or by adding water blocking structures to the plate. In this embodiment, the base 600 includes a base 610 and a mounting plate 620 mounted on the base 610, the mounting plate 620 covers the base 610 corresponding to the sub-flow channel 617, and the nozzle is mounted on the mounting plate 620. The sub-flow channels 617 are formed in a partial region of the base 610, and the mounting plate 620 covers the corresponding region and is connected to the base 610 to enclose the sub-flow channels 617 corresponding to the water outlet region. Other areas of the base 610 may provide locations for the water inlet flow channels 618, the water return flow channels 612, etc. Of course, in other areas, other flow channels 612 and the like may be provided that are not associated with the existing sub-flow channel 617.

In some embodiments, the nozzles may be provided not only on the side walls, top and bottom of the wash chamber, but also on a stand such as the bowl basket 400. The connection of the nozzle with the bowl basket 400, the bowl basket 400 provides support only for the nozzle, and water is supplied to the nozzle by providing an additional waterway system; in other embodiments, the waterway may be integrated to the bowl basket 400, i.e., the waterway system is internally disposed on the bowl basket 400, and the nozzle is only connected to the water outlet 220 formed on the bowl basket 400.
Referring to fig. 11 to 21, a spray device which can use the oscillating jet device 100 of the above embodiment will be further described.
A spray device, comprising:
the spray arm 200, the spray arm 200 has a water inlet 210, a plurality of water outlet 220 arranged along the length direction of the spray arm 200, and a flow channel communicating the water inlet 210 and the water outlet 220;
an oscillating jet nozzle 100, said oscillating jet nozzle 100 being mounted within said water outlet aperture 220;
the oscillating jet nozzle 100 forms a spray area in the spray direction along with the rotation of the spray arm, and the first spray area and the second spray area of the oscillating jet nozzle 100 respectively have a first projection and a second projection in a first plane, and the first projection and the second projection intersect. Wherein the first plane is perpendicular to the direction of injection of the oscillating jet nozzle.
Specifically, in the present embodiment, the spray arm 200 is disposed in a long strip shape, and the water inlet holes 210 are provided in 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 the requirements, and when only the spray device is required to spray upwards, the water outlet holes 220 can be formed only at the top of the spray arm 200; when spray cleaning is required for both the top of the spray arm 200 and the bottom of the spray arm 200, water outlets 220 are simultaneously formed at the top and bottom of the spray arm 200. The water outlet holes 220 are aligned in the length direction of the spray arm 200. In some embodiments, the oscillating jet nozzle 100 is exemplified as being aligned along the length of the spray arm 200.
The water surface sprayed by each oscillating jet nozzle 100 is a vertical surface formed by swinging water flow from the nozzle to the spraying direction, and the sprayed water surface of each oscillating jet nozzle 100 is arranged in a triangle shape when seen from the side. When the nozzle sprays in a vertical plane, the sprayed water surface is triangular, and the projection of the cleaning area which can be scanned by the nozzle in a horizontal plane is a straight line. If the nozzle is disposed at an angle to the vertical, the projection of the water surface sprayed from the oscillating jet nozzle 100 onto the horizontal plane is a plane.
It is noted that, with reference to fig. 21, in some embodiments, there may be relative rotation between the oscillating jet nozzle and the spray arm, i.e., the oscillating jet nozzle has an axis of rotation about which the oscillating jet nozzle rotates. At this time, the rotation axis may be perpendicular to the spray arm; in some embodiments, the rotation axis may be disposed at an angle to the spray arm in order to meet the needs of a particular operating condition. When the nozzle rotates around the rotation axis, a conical spray area is formed, and the conical spray area moves along with the rotation of the spray arm to form an annular spray area with a triangular cross section. Through making the rotation of oscillating jet nozzle for every position in the spray washing region receives multiple impact (the rotation washing of nozzle and the repeated washing after the nozzle rotates along with the spray arm), be favorable to improving the washing effect by a wide margin.
In the following, the oscillating jet nozzle 100 is described as jetting in a vertical plane, and the vertical plane may be a vertical plane perpendicular to the plane of the boom 200, as well as a vertical plane in which a plurality of nozzles are located. At this time, the vertical water surface sprayed by the oscillating jet nozzle 100 may be parallel to the spray arm 200, may form an included angle with the spray arm 200, or may be perpendicular to the spray arm 200. When the oscillating jet nozzle 100 is ejected with the rotation of the spray arm 200, the oscillating jet nozzle 100 forms a circular spray area. If the first projection and the second projection of the water surface sprayed by the oscillating jet nozzle 100 on the first plane (for example, the horizontal plane) intersect (when the projection is a straight line, the two straight lines intersect; when the projection is a plane, the two planes intersect), it is indicated that the water outlet surfaces sprayed by the adjacent nozzles (corresponding to the spraying area in the above embodiment, specifically, the cleaning plane) intersect spatially, so that the cleaning plane N sprayed by the plurality of nozzles is a continuous and uninterrupted cleaning plane M during the rotation of the spray arm 200.
In this embodiment, by providing a water flow channel and a plurality of water outlet holes 220 communicated with the water flow channel on the spray arm 200 of the washing device of the dishwasher, each water outlet hole 220 is connected with an oscillating jet nozzle 100, the oscillating jet nozzle 100 forms an annular spray area in the process of rotating along with the spray arm 200, and the spray area is three-dimensionally arranged, including a washing plane located at the top of the spray area and a connection surface located between the outlet of the nozzle 100 and the washing plane, wherein the connection surface is formed by water flow in the process of spraying to the washing plane and rotating along with the spray arm 200. Taking the example that the oscillating jet nozzle 100 sprays vertically upwards and the spray arm 200 makes complete circumferential rotation, at this time, the cleaning plane is located right above the oscillating jet nozzle 100 and is in an annular arrangement, at this time, if the two cleaning planes are located in the same horizontal plane, the two cleaning planes intersect; 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 spraying direction of the oscillating jet nozzle 100, i.e. the cleaning planes of the spraying area intersect to form a continuous cleaning plane in the spraying direction of the nozzle 100. It should be noted that, in general, the projection in the first plane, the projection of the cleaning plane covering the projection of the connection surface, i.e. the first projection and the second projection of the first and the second spray area in the first plane intersect, refers to the intersection 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. In this way, 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 plurality of oscillating jet nozzles 100 are continuous and uninterrupted, the cleaning device of the cleaning device can clean dishes and other tableware in the cleaning basket of the dish washer in an omnibearing and dead-angle-free manner, and the cleaning effect of the cleaning device of the dish washer is improved.
In order to improve the cleaning efficiency of the cleaning device, it is ensured that the cleaning area generated when the spray arm 200 rotates is a continuous and uninterrupted cleaning surface, and the first spraying area and the second spraying area intersect, for example, the corresponding first cleaning plane and the second cleaning plane intersect.
In some embodiments, in order to improve the cleaning efficiency of the cleaning device, in order to improve the number of the oscillating jet nozzles 100 to improve the utilization rate of each oscillating jet nozzle 100, the oscillating jet nozzles 100 are linearly arranged at the top and/or the bottom of the spray arm 200. I.e. the oscillating jet nozzle 100 is arranged on top of the spray arm 200 or on the bottom of the spray arm 200 or on both the top and the bottom of the spray arm 200. By arranging on the same straight line and arranging the projection of the spray area of each oscillating jet nozzle 100 in a horizontal plane as a straight line parallel to the spray arm 200, the oscillating jet nozzle will be utilized to the greatest extent. Of course, in other embodiments, the oscillating jet nozzles 100 may be arranged in different desired shapes instead of being arranged in a straight line to meet the specific requirements of specific working conditions, where the linearity includes not only a straight line but also a curve extending according to a preset rule.
In order to improve the spray washing efficiency of the oscillating jet nozzles, the oscillating jet nozzles are fully and reasonably arranged so as to improve the space utilization rate and adapt to different working condition demands, etc., the arrangement condition of the oscillating jet nozzles on the spray arm is introduced below.
The spray arm can have various shapes, and only the cleaning plane corresponding to the two oscillating jet nozzles is required to be continuous. The following description will be made by taking a straight spray arm (refer to fig. 11 to 13, with the rotation axis of the spray arm being the reference, and two spray arm sections 240 being on the same straight line), a three-fork spray arm (refer to fig. 17 to 18, with the rotation axis of the spray arm being the reference, and three spray arm sections 240 being radially arranged around the rotation axis as the center), and a cross-shaped spray arm (refer to fig. 19 and 20), respectively. Of course, the spray arm segments 240 may also be five, six or more.
More precisely, regarding the arrangement of the nozzles, a plurality of circular rings are formed by taking the rotation 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; at least one oscillating jet nozzle is arranged on each circular ring, and the oscillating jet nozzles can be arranged at any position on the circular rings. The circle center line is the axis of rotation of the spray arm, the nozzles are distributed on the spray arm, the distance between the nozzles and the rotation axis of the spray arm is taken as a radius, the circle center is positioned on the circle center line, thus forming a circle, the distance between adjacent circles 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 is, the larger the distance between adjacent circles can be, and otherwise, the smaller the distance between adjacent circles is. 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 ring-shaped cleaning plane in the rotating process of the spray arm.
In a linear spray arm, referring to fig. 11 to 13, when two oscillating jet nozzles are located on the same side of the rotation axis of the spray arm, the two oscillating jet nozzles are disposed adjacent to each other. That is, when the oscillating jet nozzles are located on the same spray arm segment 240, the two oscillating jet nozzles are disposed adjacent.
When two oscillating jet nozzles are respectively located at two sides of the rotation axis of the spray arm, that is, when the oscillating jet nozzles are located on the symmetrical spray arm section 240, one of the oscillating jet nozzles is adjacent to the other oscillating jet nozzle at a symmetrical mapping position with respect to the rotation axis of the spray arm.
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 other than 180 °, for example, 120 °,170 °, or the like. Of course, in some embodiments, all of the nozzles may be arranged on different boom sections 240 of the boom, or may be provided only on the same boom section 240.
Referring to fig. 17 to 18, three spray arm sections 240 have one end connected to the rotation axis and the other end extending in a direction away from the rotation axis, and the three spray arm sections 240 are disposed at an angle of 120 ° in pairs. Of course, in some embodiments, the included angle between every two may be adjusted according to more practical requirements, such as 100 °, 160 °, and so on.
The cross spray arm, referring to fig. 19-20, includes four spray arm segments 240, and is symmetrical two by two, i.e. the included angle between two adjacent spray arm segments 240 is 90 °, and of course, in some embodiments, the included angle between two adjacent spray arm segments 240 may be adjusted according to actual requirements.
In order to rotate the spray arm 200, a driving device such as a motor may be provided to drive the spray arm 200 to rotate, or a reaction force at the time of water spraying may be used. Specifically, the spray device further includes a driving nozzle 230, where the driving nozzle 230 is disposed at a side portion of two ends of the spray arm 200 to drive the spray arm 200 to rotate, and a cleaning area of the oscillating jet nozzle 100 disposed at the top and/or bottom of the spray arm 200 forms a cleaning annulus along with the rotation of the spray arm 200. The driving nozzles 230 are disposed at opposite sides, i.e., diagonally, of both ends of the spray arm 200 such that the reaction force exerted on the spray arm 200 by the driving nozzles 230 at both ends is reversed, thereby driving the spray arm 200 to rotate.
The positional relationship between adjacent nozzles is not only applicable to the present embodiment, but also to other embodiments, and is particularly applicable to a condition where the spray arm does not rotate, or even does not exist.
The first spray-washing region comprises a first radiation region and a first sputtering region which are connected, and the second spray-washing region comprises a second radiation region and a second sputtering region which are connected;
the first radiation area and the second radiation area respectively have a first vertical projection and a second vertical projection in a second plane, wherein the second plane is perpendicular to the first plane; the included angles of the first vertical projection and the second vertical projection taking the projection of the oscillating jet nozzle in the second plane as the vertex are alpha respectively 1 And alpha 2 The method comprises the steps of carrying out a first treatment on the surface of the The heights of the first vertical projection and the second vertical projection are h respectively 1 And h 2 ；
The difference between the distances between the two oscillating jet nozzles and the rotation axis of the jet arm is greater than 0 and less than or equal to:
[h 1 tan(α 1 /2)+h 2 tan(α 2 /2)]*(1+15％)。
wherein alpha is 1 And alpha 2 And, h 1 And h 2 Is influenced by factors such as the manufacturing and assembling of the nozzle, the included angle with the spray arm 200, the distance from the water inlet 611, and the like, when alpha 1 ＝α 2 ；h 1 ＝h 2 The method comprises the steps of carrying out a first treatment on the surface of the When the distance between two adjacent oscillating jet nozzles 100 in the horizontal plane is less than or equal to:
2h 1 tan(α 1 (1+15%) or 2h 2 tan(α 2 /2)*(1+15％)
By setting the distance between the two adjacent oscillating jet nozzles 100 in this way, the intersection of the cleaning planes of the adjacent spray areas is ensured, and thus 360-degree dead-angle-free spray cleaning during rotation of the spray arm 200 is effectively ensured.
Wherein, the movement condition of the water is influenced by the nozzle structure within a certain range after the water leaves the nozzle, and a radiation area of the nozzle is formed within a certain range, namely, the coverage area of the water flow is controlled by the nozzle in the radiation area; when the water flows leave the radiation area, collision between the water flows and splashing of the water flows can occur during the continuous movement of the water flows due to the fact that the water flows still have movement states (kinetic energy, potential energy and the like), and the coverage area of the water flows is not completely controlled by the nozzles due to a plurality of influencing factors in the area, wherein the area is a splashing area.
Taking the above formula as an example, one specific example of the radiation area and sputtering area range is given below:
the width of the first radiation area is 2h 1 tan(α 1 And/2) the width of the first sputtering region is less than or equal to h 1 tan(α 1 2) ×15%; the width of the second radiation area is 2h 2 tan(α 2 And/2) the width of the second sputtering region is less than or equal to h 2 tan(α 2 /2)*15％。
It is worth to be noted that, regarding the positional relationship between the two oscillating jet nozzles and the second plane in the projection process, the two adjacent oscillating jet nozzles can be both in the projected second plane, and at this time, the projection of the oscillating jet nozzles in the second plane is the self; one or two adjacent oscillating jet nozzles can also be not in the projected second plane, and the jet included angle alpha 1 And alpha 2 Is the projection of the oscillating jet nozzle in the corresponding second plane. With respect to angle alpha 1 And alpha 2 Referring to fig. 13 and 14, an included angle α of the first vertical projection is formed by taking the projection of the nozzle on the second plane as an apex, and taking the boundary line of the projection of the spray area of the oscillating jet nozzle on the second plane as an angle line 1 Included angle alpha with the second vertical projection 2 。
In other embodiments, the definition and calculation may be performed in different ways, as follows:
the first spray region comprises a first cleaning plane parallel to the first plane, and the second spray region comprises a second cleaning plane parallel to the first plane; it can be understood that parallel includes parallel, and allows deviation from parallel state in a certain range, so that the states of the first cleaning plane and the second cleaning plane can accommodate specific working condition requirements, that is, under the influence of actual working condition, the positional relationship between the cleaning plane and the first plane still satisfies the parallel relationship.
The spray angles of the two oscillating jet nozzles are alpha respectively 1 And alpha 2 The method comprises the steps of carrying out a first treatment on the surface of the The distance between the water outlets of the two oscillating jet nozzles and the first cleaning plane and the second cleaning plane is h respectively 1 And h 2 ；
Taking the distance between the oscillating jet nozzles and the rotating axis of the spray arm as a radius, wherein the difference between the radius of the circumference where the two oscillating jet nozzles are positioned is more than 0 and less than or equal to:
[h 1 tan(α 1 /2)+h 2 tan(α 2 /2)]*(1+15％)。
wherein alpha is 1 And alpha 2 And, h 1 And h 2 Is influenced by factors such as the manufacturing and assembling of the nozzle, the included angle with the spray arm 200, the distance from the water inlet 611, and the like, when alpha 1 ＝α 2 ；h 1 ＝h 2 The method comprises the steps of carrying out a first treatment on the surface of the When the distance between two adjacent oscillating jet nozzles 100 in the horizontal plane is less than or equal to:
2h 1 tan(α 1 (1+15%) or 2h 2 tan(α 2 /2)*(1+15％)
It should be noted that, when the distance between two oscillating jet nozzles in the case where the spray arm does not rotate or is not provided with the spray arm is calculated in this way, the distance between the two oscillating jet nozzles and the rotation axis of the spray arm in the above embodiment may be 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 "replace" with "that the distance between the two adjacent oscillating jet nozzles is greater than 0 and less than or equal to", that is, the distance between the two adjacent oscillating jet nozzles may be directly calculated according to the above parameters.
Wherein, the movement condition of the water is influenced by the nozzle structure within a certain range after the water leaves the nozzle, and a radiation area of the nozzle is formed within a certain range, namely, the coverage area of the water flow is controlled by the nozzle in the radiation area; when the water flows leave the radiation area, collision between the water flows and splashing of the water flows can occur during the continuous movement of the water flows due to the fact that the water flows still have movement states (kinetic energy, potential energy and the like), and the coverage area of the water flows is not completely controlled by the nozzles due to a plurality of influencing factors in the area, wherein the area is a splashing area.
Taking the above formula as an example, one specific example of the radiation area and sputtering area range is given below:
the width of the first radiation area is 2h 1 tan(α 1 And/2) the width of the first sputtering region is less than or equal to h 1 tan(α 1 2) ×15%; the width of the second radiation area is 2h 2 tan(α 2 And/2) the width of the second sputtering region is less than or equal to h 2 tan(α 2 /2)*15％。
In order to further improve the cleaning accuracy, the distance between two adjacent oscillating jet nozzles 100 gradually decreases 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 smaller than the water pressure of the nozzles near the water inlet 210, so that the spray ranges and heights of the nozzles at different distances from the water inlet 210 are different. In order to minimize the influence of water pressure on the nozzle spray, the distance between the nozzles is adjusted. The distance between nozzles far from the water inlet holes 210 is shortened to ensure that the cleaning areas sprayed by the adjacent two oscillating jet nozzles 100 are spatially connected to ensure the continuity of the cleaning areas formed by the rotation of the spray arm 200.
It should be noted that the spray arm 200 is in waterway communication with the water pump 300 of the dishwasher, and in order to ensure that the spray arm 200 is always in waterway communication with the water pump 300, in an embodiment of the present invention, the spray device further includes a flexible connection pipe, which may be a hose, a spring pipe, etc., not shown, one end of which is in communication with the spray arm 200 and the other end of which is in communication with the water pump 300. Because the flexible connecting pipe has better flexibility, when the spray arm 200 moves relative to the water pump 300, the flexible connecting pipe can adapt to the deformation of the flexible connecting pipe, so that the problem that the flexible connecting pipe falls off from the spray arm 200 or the water pump 300 is avoided.
The present invention also proposes a household cleaning apparatus 500, where the household cleaning apparatus 500 includes a liner and a spraying device, and the specific structure of the spraying device refers to the above embodiment, and since the household cleaning apparatus 500 adopts all the technical solutions of all the embodiments, at least has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.
