Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of a spray washing device of the present invention, and fig. 2 is a schematic structural diagram of an embodiment of a household washing apparatus of the present invention. The invention provides a spray washing device 100, which is applied to a household washing device 1000, wherein the spray washing device 100 is arranged above, below or on the side of a washing basket 200 of the household washing device 1000

The spray device 100 comprises a spray arm 10, a plurality of oscillating jet spray heads 20 and a driving device 30; the spray arm 10 is provided with a water flow channel 11 communicated with a water source and a plurality of water outlets 12 communicated with the water flow channel 11, each water outlet 12 is connected with one oscillating jet flow nozzle 20, and the driving device 30 is connected with the spray arm 10 and is used for driving the spray arm 10 to make reciprocating translation; the water in the water flow channel 11 forms a spraying area after being sprayed out by each oscillating jet flow nozzle 20, each oscillating jet flow nozzle 20 forms a belt-shaped cleaning area when moving along with the spray arm 10, and the projections of the cleaning areas of any two adjacent oscillating jet flow nozzles 20 in the movement plane of the spray arm 10 are arranged in an intersecting manner.

Referring to fig. 3 and 4, the nozzle arm 10 may be in various shapes, such as a long strip shape, a flat plate shape, or other shapes, and the shape of the nozzle arm 10 is not limited specifically herein. The water flow channel 11 of the spray arm 10 may be a straight water flow channel 11, a curved water flow channel 11, or a mixture of straight and curved water flow channels 11, and the shape of the water flow channel 11 is not particularly limited.

It should be noted that the water flow channel 11 of the spray arm 10 is communicated with the water pump 300 of the household cleaning apparatus 1000, and in order to facilitate the communication between the water flow channel 11 of the spray arm 10 and the water pump 300 of the household cleaning apparatus 1000, in an implementation of the present invention, the spray arm 10 is provided with an adapter 13 communicated with the water flow channel 11, the adapter 13 may be a linear type or a curved type, where the shape of the adapter 13 is not specifically limited, and the specific shape of the adapter 13 may be set according to actual circumstances.

Referring to fig. 5, each of the oscillating jet nozzles 20 includes an oscillating cavity 21, a water inlet cavity 22, a water outlet cavity 23, and two feedback loops 24; wherein, the inlet of the oscillation cavity 21 is communicated with the water inlet cavity 22, and the outlet of the oscillation cavity 21 is communicated with the water outlet cavity 23; the two feedback loops 24 are respectively arranged on two opposite sides of the oscillation cavity 21, one end of each feedback loop 24 is communicated with the joint of the inlet of the oscillation cavity 21 and the water inlet cavity 22, and the other end of each feedback loop 24 is communicated with the joint of the outlet of the oscillation cavity 21 and the water outlet cavity 23; one end of the water inlet cavity 22, which is far away from the oscillation cavity 21, is communicated with the water outlet 12; the end of the water outlet chamber 23 away from the oscillation chamber 21 is disposed toward the washing basket 200. The water in the water flow channel 11 will form a water column swinging back and forth in a vertical plane after being ejected by each oscillating jet flow nozzle 20, and the amplitude of the water column ejected by each oscillating jet flow nozzle 20 increases from the direction in which the oscillating jet flow nozzle 20 is back away from the oscillating jet flow nozzle 20, that is, each of the ejecting areas of the oscillating jet flow nozzle 20 increases from the direction in which the oscillating jet flow nozzle 20 is back away from the oscillating jet flow nozzle 20, that is, each of the cleaning areas in which the oscillating jet flow nozzle 20 ejects water is a sector area.

It should be noted that whether the water column sprayed by each oscillating jet nozzle 20 is stable affects the cleaning effect of the spray device 100, and in order to ensure that the water column sprayed by each oscillating jet nozzle 20 is stable, in an embodiment of the present invention, the structure of the oscillating jet nozzle 20 is further optimized, specifically, referring to fig. 5, a vertical distance between an inlet and an outlet of the oscillating cavity 21 is h, a width of the oscillating cavity 21 along a direction perpendicular to a connecting line between the inlet and the outlet of the oscillating cavity is w, and h/w is greater than or equal to 1.5 and less than or equal to 2. Due to the arrangement, on one hand, the process that water oscillates in the oscillation cavity 21 is ensured to be more stable; on the other hand, the energy loss of the water in the oscillation cavity 21 is reduced, so that the problem that the oscillation of the water in the oscillation cavity 21 causes large vibration of the oscillating jet spray head 20 is avoided.

Further, the oscillating jet flow nozzle 20 further comprises a water passing channel 25 for communicating the inlet of the oscillating cavity 21 with the water inlet cavity 22, the width of the end of the water passing channel 25 connected with the inlet of the oscillating cavity 21 is f, the width of the end of the water passing channel 25 connected with the water inlet cavity 22 is d, wherein d/w is greater than or equal to 0.35 and less than or equal to 0.55, and d/f is greater than or equal to 0.8 and less than or equal to 1.2. With such an arrangement, it is further ensured that the process of water oscillation in the oscillation cavity 21 is more stable, so that each oscillation jet spray head 20 does not generate large vibration when spraying water.

In order to further improve the stability of the water column sprayed by each oscillating jet nozzle 20, each water outlet cavity 23 may also be arranged in a tapered manner, that is, the width of the water outlet cavity 23 gradually decreases from the end adjacent to the oscillating cavity 21 to the end away from the oscillating cavity 21, and the cavity wall of the water outlet cavity 23 and the axis of the water outlet cavity 23 are arranged at an included angle of 10 ° to 30 °. This ensures that the water outlet chamber 23 can converge, which is advantageous for improving the stability of the water column sprayed by the oscillating jet nozzle 20.

It should be reminded that the included angle of the spraying area of the oscillating jet spray head 20 can be increased when the oscillating jet spray head 20 needs to satisfy one or more of the above conditions, so that one or more parameters of the oscillating jet spray head 20 can be changed according to actual conditions, so that the included angle of the spraying area of the oscillating jet spray head 20 satisfies the requirements.

It should be further noted that the included angle of the spraying area formed by the water column sprayed by the oscillating jet nozzle 20 is related to the outlet width of the water outlet cavity 23 of the oscillating jet nozzle 20, the included angle between the cavity wall of the water outlet cavity 23 and the axis of the water outlet cavity 23, and the width of the oscillating cavity 21 along the direction perpendicular to the connecting line of the inlet and the outlet of the oscillating cavity. Specifically, the outlet width of the water outlet cavity 23 of the oscillating jet flow nozzle 20 is increased, the included angle between the cavity wall of the water outlet cavity 23 of the oscillating jet flow nozzle 20 and the axis of the water outlet cavity 23 is increased, or the width of the oscillating cavity 21 in the direction perpendicular to the inlet and outlet connecting line can be increased, so that the spraying area of the water column sprayed by the oscillating jet flow nozzle 20 can be increased.

When the spray device 100 is in operation, water entering the water flow channel 11 of the spray arm 10 is sprayed from the plurality of oscillating jet spray heads 20, so that each oscillating jet spray head 20 forms a spray area in the direction of spraying water, when the driving device 30 drives the spray arm to reciprocate, each oscillating jet flow nozzle 20 forms a belt-shaped cleaning area along with the movement of the spray arm 10, the projections of the cleaning areas of any two adjacent oscillating jet flow nozzles 20 in the movement plane of the spray arm 10 are intersected, this allows the cleaning zones of a plurality of oscillating jet spray heads 20 to be connected in series, that is, the cleaning zone of the spray device 100 is continuous and uninterrupted, thus, the spray washing device 100 can clean dishes, dishes and other tableware in all directions without dead angles, and the cleaning effect of the spray washing device 100 is improved.

In addition, projections of cleaning areas of any two adjacent oscillating jet flow sprayers 20 in the movement plane of the spray arm 10 are arranged in an intersecting manner, so that the problem that the heights and widths of the spraying areas of the two adjacent oscillating jet flow sprayers 20 are different due to the manufacturing process of the oscillating jet flow sprayers 20, the installation error of the oscillating jet flow sprayers 20, unstable water pressure and other factors, and further the cleaning areas of the two adjacent oscillating jet flow sprayers 20 are discontinuous can be effectively solved.

In addition, compared to the existing spray arm 10 in which each water outlet 12 is directly used for spraying water, in the embodiment of the present invention, each water outlet 12 of the spray arm 10 is connected to one oscillating jet nozzle 20, so that the problem of water leakage at each water outlet 12 is avoided, and the water in the water flow channel 11 is fully utilized.

It should be noted that the oscillating jet spray heads 20 may be arranged regularly on the spray arm 10 or irregularly on the spray arm 10. The irregular arrangement of the oscillating jet heads 20 not only results in a larger volume of the spray arm 10, but also results in a higher accuracy requirement for the installation position of the oscillating jet heads 20. In view of this, in an embodiment of the present invention, a plurality of oscillating jet spray heads 20 are arranged according to a certain rule, and the spray area of each oscillating jet spray head 20 is connected with the spray area of the adjacent oscillating jet spray head 20. With such arrangement, on one hand, the spraying areas of the oscillating jet flow nozzles 20 are sequentially connected and uninterrupted, so that the cleaning areas of any two adjacent oscillating jet flow nozzles 20 are connected, and further the cleaning areas of the oscillating jet flow nozzles 20 are continuous and uninterrupted water curtains, which is convenient for washing dishes such as bowls and dishes; on the other hand, the volume of the spray arm 10, i.e., the length and width of the spray arm 10, can be reduced, which is advantageous in reducing the volume of the spray device 100.

Further, the arrangement of the oscillating jet spray heads 20 is closely related to the arrangement of the water outlets, and the arrangement of the water outlets 12 on the spray arm 10 is various, so the arrangement of the oscillating jet spray heads 20 is also various. For example, the water outlets 12 are linearly arranged at intervals, and if the water outlets 12 are arranged at intervals in an arc, a part of the water outlets 12 may be linearly arranged at intervals, and another part may be arcuately arranged at intervals, which are not listed herein. Preferably, referring to fig. 3 or fig. 4, the plurality of water outlets 12 are linearly arranged at intervals, so that the number of the oscillating jet nozzles 20 can be reduced, and the production cost of the spray washing apparatus 100 can be further reduced.

It should be noted that the water column sprayed by each oscillating jet flow nozzle 20 is oscillating back and forth in a plane perpendicular to the movement plane of the spray arm 10, and the spraying areas of two adjacent oscillating jet flow nozzles 20 are intersected, so that the plane where the spraying area of each oscillating jet flow nozzle 20 is located and the plane where the spraying area of the adjacent oscillating jet flow nozzle 20 is located may form an included angle of 0 to 180 degrees.

When the plane where the jetting area of each oscillating jet flow sprayer 20 is located is coplanar with the plane where the jetting area of the adjacent oscillating jet flow sprayer 20 is located, at this time, the jetting areas of a plurality of oscillating jet flow sprayers 20 are located in the same plane, and the distance between any two adjacent oscillating jet flow sprayers 20 is the largest, so that the number of the oscillating jet flow sprayers 20 to be used can be reduced, and the production cost of the spray washing device 100 is further reduced.

When the plane where the injection region of each oscillating jet flow sprayer 20 is located is perpendicular to the plane where the injection region of the adjacent oscillating jet flow sprayer 20 is located, at this time, the planes where the injection regions of the adjacent two oscillating jet flow sprayers 20 are perpendicular to each other, and the planes where the injection regions of the two oscillating jet flow sprayers 20 which are spaced apart from each other are parallel to each other. So set up, make two adjacent the water column that oscillating jet 20 jetted is along different direction wobbling, so have to be convenient for wash tableware such as bowl, dish.

It should be noted that the plane of the spraying region of each oscillating jet sprayer 20 is perpendicular to the plane of the spraying region of the adjacent oscillating jet sprayer 20, and it can be understood that the edge of one side of the spraying region of each oscillating jet sprayer 20 is connected to the edge of one side of the spraying region of the adjacent oscillating jet sprayer 20, and the plane of the spraying region of each oscillating jet sprayer 20 is perpendicular to the plane of the cleaning region of the adjacent oscillating jet sprayer 20, so that the spraying regions of the adjacent oscillating jet sprayers 20 are V-shaped. Of course, it can also be understood that the middle of the spraying region of each oscillating jet nozzle 20 is connected with the edge of one side of the spraying region of the adjacent oscillating jet nozzle 20, and the plane where the spraying region of each oscillating jet nozzle 20 is located is perpendicular to the plane where the cleaning region of the adjacent oscillating jet nozzle 20 is located, so that the spraying regions of the adjacent oscillating jet nozzles 20 are in a T shape.

It should be noted that the water leaving the oscillating jet spray head 20 is within a certain range, and is influenced by the structure of the oscillating jet spray head 20 to form a radiation area, which is the coverage area of the water and is controlled by the oscillating jet spray head; after the water leaves the radiation area, the water still has a motion state (kinetic energy, potential energy and the like), and the water collides or sputters to form a sputtering area in the process of continuing moving, but the sputtering area is not controlled by the oscillating jet nozzle.

That is, the distance between two adjacent oscillating jet sprayers 20 needs to be set by considering not only the radiation area of the oscillating jet sprayers 20 but also the sputtering area of the oscillating jet sprayers 20, and in an embodiment of the present invention, referring to fig. 6, the included angles of the radiation areas of any two adjacent oscillating jet sprayers 20 in a plane perpendicular to the movement plane of the spray arm 10 are α respectively₁、α₂The heights of the radiation areas of any two adjacent oscillating jet flow spray heads 20 in a plane vertical to the movement plane of the spray arm 10 are h₁、h₂The distance between any two adjacent oscillating jet spray heads 20 is more than 0 and less than or equal to [ h₁tan(α₁/2)+h₂tan(α₂/2)]*(1+15％)。

In order to improve the spraying effect of the spraying device 100, in an embodiment of the present invention, referring to fig. 7, each oscillating jet nozzle 20 can rotate relative to the spray arm 10, specifically, each oscillating jet nozzle 20 has a rotation axis, each oscillating jet nozzle 20 is mounted on the spray arm 10, and each oscillating jet nozzle 20 can rotate along its own rotation axis. So set up, when oscillating jet 20 rotates around its axis of rotation, the water column that oscillating jet 20 spun can form and be conical injection zone, has just so increased each the injection zone of oscillating jet 20 is in the projection in spray arm 10 motion plane, thereby also make each every position in the injection zone of oscillating jet 20 can receive multiple impact (the rotation of oscillating jet 20 is washed and oscillating jet 20 is along with the repeated washing after the spray arm removes), and then be favorable to improving spray washing device 100's spray washing effect.

It should be noted that there are many driving devices 30 for driving the spray arm 10 to reciprocate, and in an embodiment of the present invention, referring to fig. 1, the driving device 30 includes two driving assemblies 31 arranged in parallel, two ends of the spray arm 10 are respectively connected to one of the driving assemblies 31, and the spray arm 10 is driven by the two driving assemblies 31 to reciprocate.

Specifically, each driving component 31 includes a motor 311, a roller 312 and a belt 313, the motor 311 and the roller 312 of each driving component 31 are arranged at intervals, one end of the belt 313 of each driving component 31 is matched with an output shaft of the corresponding motor 311, the other end of the belt 313 of each driving component 31 is matched with the corresponding roller 312, and each belt 313 is further connected with one end of the spray arm 10.

Obviously, each of the driving assemblies 31 may also be composed of a motor, a gear and a rack, and each of the driving assemblies may also be composed of a motor, a sprocket and a chain, which are not necessarily enumerated herein.

It should be noted that the spray arm 10 is in communication with a water pump 300 of the household cleaning device 1000, and since the spray arm 10 is driven by the driving device 30 to displace relative to the water pump 300, in order to ensure that the spray arm 10 can be always in communication with the water pump 300, in an embodiment of the present invention, referring to fig. 2, the spray device 100 further includes a flexible connection pipe 40, where the flexible connection pipe 40 may be a hose, a spring pipe, or the like, for example, one end of the flexible connection pipe 40 is in communication with the spray arm 10, and the other end of the flexible connection pipe 40 is in communication with the water pump 300. Because the flexible connection pipe 40 has good flexibility, when the spray arm 10 moves relative to the water pump 300, the length of the flexible connection pipe 40 can be changed through the deformation of the flexible connection pipe 40, so that the problem that the flexible connection pipe 40 falls off from the spray arm 10 or the water pump 300 is avoided.

Referring to fig. 2, the household cleaning apparatus 1000 includes a spraying device 100, a cleaning basket 200, and a water pump 300, and the specific structure of the spraying device 100 refers to the above embodiments, and since the household cleaning apparatus adopts all technical solutions of all the above embodiments, the household cleaning apparatus at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated here.
