Description

Spraying device of dish washer and dish washer
Technical Field
The invention belongs to the field of dish washers, and particularly relates to a spraying device of a dish washer and the dish washer.
Background
The existing dishwashers generally adopt a linear or star-shaped structure, and wash by rotating around an intermediate shaft. The sprayer adopts a cavity structure, water outlets are formed in the cavity wall, water spraying washing can be completed under the action of water pressure after the sprayer is connected to a waterway, and the sprayed water flow can also push the sprayer to perform rotary motion.
The existing linear type sprayer moves circularly around the intermediate shaft during washing, so that the washing area is circular, the space in the inner container cavity is mostly square in consideration of factors such as placement stability and capacity of a dish washer, and dead angles are formed at four corners of the inner container cavity when the existing sprayer structure is used for washing, and tableware cannot be sufficiently washed. In addition, during the washing process, water flows are sprayed onto the wall of the liner and flow back to the water tank, and the adoption of the sprayer with the nozzles arranged linearly can enable the water to flow back and the absorption capacity of the washing pump to be mismatched, so that the water flow of the water tank is unstable, and the air is pumped into the washing pump.
In view of this, the present invention has been made.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and providing a spraying device of a dish washer, which adopts a sprayer capable of rotating by itself as an axis and nozzles spirally arranged at the periphery of the sprayer, so that the sprayed water flow can cover all space areas of a cavity of a flushing liner.
In order to solve the technical problems, the invention adopts the basic conception of the technical scheme that:
The invention provides a dishwasher spray device, comprising: the sprayer 1 is rotatably connected with the inner container wall of the dish washer and has the rotation freedom degree taking the length direction of the sprayer as an axis; the spray nozzles 11 are distributed on the outer peripheral surface of the sprayer 1 at intervals along the length direction of the sprayer 1.
In the above scheme, the sprayer 1 of the application extends from the side wall of the inner container cavity of the dish washer to the middle, namely, the inner container cavity is suspended, and the spray nozzles 11 which are not in linear arrangement are arranged around the outer peripheral surface of the sprayer, and the sprayer 1 can rotate by taking the sprayer as an axis, so that water flow sprayed by the spray nozzles 11 is diffused outwards along the radial direction of the sprayer 1, and the coverage flushing of the space area of the inner container cavity of the dish washer is realized.
The invention further provides the following scheme: the nozzles 11 are arranged at intervals in the circumferential direction of the sprayer 1; preferably, adjacent spouts 11 are offset in the longitudinal direction and the circumferential direction of the sprinkler 1.
In the above scheme, unlike the scheme in the prior art that the nozzles are arranged on the long straight spray arm along a straight line, the nozzles 11 are distributed at intervals in the circumferential direction of the sprayer 1, so that the connecting lines of the centers of the radial surfaces of the nozzles 11 and the corresponding nozzles point to different directions, and the outward diffusion of the water jet along different directions is realized; the adjacent nozzles 11 are staggered in the longitudinal direction and the circumferential direction of the sprayer 1, so that the flexibility of the water flow direction can be further improved.
The invention further provides the following scheme: the nozzles 11 are arranged on the periphery of the sprayer 1 along a spiral line, and guide the water jet to flush all areas of the inner container cavity.
In the scheme, the principle of generating the cylindrical spiral line is that a moving point does uniform linear motion along a generatrix of the cylinder, and meanwhile, the generatrix does uniform angular velocity rotation around the axis of the cylinder, and the motion track of the moving point is the cylindrical spiral line. In the application, a plurality of nozzles 11 which are spirally arranged on the peripheral surface of the sprayer 1 are connected to form a spiral line surrounding the sprayer 1, when the sprayer 1 rotates by taking the sprayer as an axis, the spiral line can be regarded as being formed by a plurality of moving points, so that the nozzles 11 are connected to form a motion track which is propelled in the same direction on the surface of the sprayer 1 by the spiral line, and meanwhile, water flows sprayed by the nozzles 11 also periodically flush different space areas along with the rotation of the sprayer 1, so that flushing water flows can cover a cylinder-like space area taking the sprayer 1 as an axis and taking the water flow spraying distance as a radius.
The invention further provides the following scheme: the direction of the spray nozzles 11 is set at a certain included angle with the diameter of the spray nozzle 1 passing through the center of the spray nozzle 11 in the radial direction, and the direction of each spray nozzle 11 is the same as the included angle with the diameter passing through the center; preferably, the orientation of the spout 11 is arranged perpendicular to the axial direction of the sprinkler 1.
In the above scheme, the nozzles 11 are slightly inclined, and the inclination direction of the nozzles is opposite to the rotation direction of the sprayer 1, that is, a certain included angle is formed between the direction of the water jet flow of the nozzles 11 and the diameter of the sprayer 1 passing through the nozzles 11 in the radial direction, and meanwhile, when the included angle between the diameter of each nozzle 11 passing through the center of each nozzle is the same, the inclination direction is the same, so that the sprayer 1 rotates with itself as the axis under the propulsion of the water jet flow. The direction of water jet should not appear as a split vector in the axial direction of the sprinkler 1, so the direction of water jet, i.e. the orientation of the spout 11, is arranged perpendicular to the axial direction of the sprinkler 1.
The invention further provides the following scheme: the orientation of the jet 11 coincides with a tangent to the sprayer 1 that passes circumferentially through said jet 11.
In the above scheme, in order to better improve the effect of jet propulsion rotation, the water flow jet direction is arranged in a tangential manner with the periphery of the sprayer 1, so that the effect of water flow propulsion on the rotation of the sprayer 1 is further improved.
The invention further provides the following scheme: the pitch of the spiral line in which the nozzles 11 are arranged is smaller than the length of the shower 1.
In the scheme, the pitch is the distance between two adjacent threads obtained along the spiral line direction, the pitch is smaller than the length of the sprayer 1, namely, the thread lines formed by arranging the nozzles 11 rotate at least 360 degrees around the outer peripheral surface of the sprayer 1, so that the outer peripheral surface of the sprayer 1 is provided with the nozzles 11 which are densely arranged, and the spraying cleaning effect is improved. The application can adjust the pitch of the spiral line formed by connecting the nozzles 11 according to actual use requirements, or reduce the number of the nozzles 11 in a partial area by increasing the pitch.
The invention further provides the following scheme: the spiral lines formed by arranging the nozzles 11 are equidistantly or unequally arranged, the intervals of the nozzles 11 arranged on the shorter pitch part of the spiral lines are smaller than those of the nozzles 11 arranged on the longer pitch part, and the intervals of the nozzles 11 are the same when the spiral lines are equidistant.
In the scheme, the equidistant spiral is the spiral line formed by the nozzles 11 and has the same pitch, so that the sprayed water flow covers a cylinder-like space area taking the sprayer 1 as an axis and the water flow spraying distance as a radius, and the sprayed water flow is more uniform; when the spiral line formed by the spray nozzles 11 adopts non-equidistant spiral, the screw pitch can be lengthened in the area with less bowl tools, the number of the spray nozzles 11 is reduced, and the number of the spray nozzles 11 is increased in the area with concentrated bowl tools, so that the overall cleaning effect is improved, and meanwhile, the flushing of unnecessary areas is reduced, so that the speed of backflow water is controlled, and the normal operation of the washing pump is ensured; or a plurality of non-rotatable sprayers 1 are arranged, and different unequally-spaced spiral arrangements are adopted for the spray nozzles 11 of each sprayer 1 according to different positions of the sprayers in the dish-washing machine so as to realize the flushing schemes corresponding to different areas.

The application can also be realized in other ways, for example, a rotatable structure with a preset water channel opening is arranged at the water outlet 21 of the water diversion pipeline in an outward protruding way, and then the first end of the sprayer 1 is fixedly connected with the rotatable structure, so that the sprayer 1 rotates by taking the sprayer as a shaft. In addition, the sprayer 1 with the second end closed design can be adopted, so that a plug structure is omitted, and the installation structure is simpler and easier to operate.
The invention further provides the following scheme: the rotation axis of the sprayer 1 is perpendicular to the side wall of the inner container cavity, so that the sprayer 1 is horizontally arranged in the inner container cavity of the dish washer; preferably, the sprayer 1 is connected to the symmetrical central line of the corresponding side wall, and the symmetrical central line is perpendicular to the bottom surface of the liner cavity; more preferably, the sprayer 1 is connected to the geometric center of the corresponding side wall.

In this embodiment, the sprayer 1 of the application extends from the side wall of the inner container cavity of the dish washer to the middle, namely, the inner container cavity is suspended, and the spray nozzles 11 which are not in linear arrangement are arranged around the outer peripheral surface of the sprayer, the sprayer 1 can rotate by taking the sprayer as an axis, so that the water flow sprayed by the spray nozzles 11 is diffused outwards along the radial direction of the sprayer 1, and the coverage flushing of the space area of the inner container cavity of the dish washer is realized.
In this embodiment, the nozzles 11 are spaced apart from each other in the circumferential direction of the sprayer 1; preferably, adjacent spouts 11 are offset in the longitudinal direction and the circumferential direction of the sprinkler 1.
In this embodiment, unlike the solution in the prior art that the nozzles are arranged on the long straight spray arm along a straight line, the nozzles 11 are distributed at intervals in the circumferential direction of the sprayer 1, so that the connection lines between the respective nozzles 11 and the centers of the corresponding radial surfaces point to different directions, and the outward diffusion of the water jet along different directions is realized; the adjacent nozzles 11 are staggered in the longitudinal direction and the circumferential direction of the sprayer 1, so that the flexibility of the water flow direction can be further improved.
In this embodiment, the nozzles 11 are arranged along a spiral line on the outer periphery of the sprinkler 1, and direct the water jet to flush all areas of the liner cavity.
In this embodiment, the principle of generating the cylindrical spiral line is that a moving point makes uniform linear motion along a generatrix of the cylinder, and at the same time, the generatrix makes uniform angular velocity rotation around an axis of the cylinder, and a motion track of the moving point is the cylindrical spiral line. In the application, a plurality of nozzles 11 which are spirally arranged on the peripheral surface of the sprayer 1 are connected to form a spiral line surrounding the sprayer 1, when the sprayer 1 rotates by taking the sprayer as an axis, the spiral line can be regarded as being formed by a plurality of moving points, so that the nozzles 11 are connected to form a motion track which is propelled in the same direction on the surface of the sprayer 1 by the spiral line, and meanwhile, water flows sprayed by the nozzles 11 also periodically flush different space areas along with the rotation of the sprayer 1, so that flushing water flows can cover a cylinder-like space area taking the sprayer 1 as an axis and taking the water flow spraying distance as a radius.
In this embodiment, the direction of the nozzle 11 forms a certain included angle with the diameter of the sprinkler 1 passing through the center of the nozzle 11, and the direction of each nozzle 11 is the same as the included angle of the diameter passing through the center; preferably, the orientation of the spout 11 is arranged perpendicular to the axial direction of the sprinkler 1.

The direction of water jet should not appear as a split vector in the axial direction of the sprinkler 1, so the direction of water jet, i.e. the orientation of the spout 11, is arranged perpendicular to the axial direction of the sprinkler 1.
In this embodiment, the pitch of the spiral line in which the nozzles 11 are arranged is smaller than the length of the sprinkler 1.
In this embodiment, the pitch is the distance between two adjacent threads obtained along the spiral line direction, and the pitch is smaller than the length of the sprayer 1, that is, the thread line formed by arranging the nozzles 11 rotates at least 360 ° around the outer peripheral surface of the sprayer 1, so that the outer peripheral surface of the sprayer 1 has the more densely arranged nozzles 11, and the spray cleaning effect is improved. The application can adjust the pitch of the spiral line formed by connecting the nozzles 11 according to actual use requirements, or reduce the number of the nozzles 11 in a partial area by increasing the pitch.

In this embodiment, equidistant spirals are spiral lines formed by the nozzles 11 and have the same pitch, and the intervals of the nozzles 11 are the same when the spiral lines are equidistant, so that the sprayed water flow covers a cylinder-like space region with the sprayer 1 as an axis and the water flow spraying distance as a radius, and the sprayed water flow is more uniform.
In this embodiment, as shown in fig. 2 to 4, a water diversion pipeline 2 is provided on the inner container wall of the dishwasher, the sprayer 1 is of a hollow tubular structure, a plurality of nozzles 11 are provided on the outer peripheral surface, a water outlet 21 of the sprayer 1 extending into the water diversion pipeline 2 is in sealed rotation connection with a bearing sleeve 22 fixed at the water outlet 21, and a plug is provided at a second end 13 of the sprayer 1.
In this embodiment, the first end of the sprayer 1 is in sealed rotatable connection with the water conduit 2, and this function is achieved by a bearing housing 22 provided at the water outlet 21 of the water conduit 2. The application can also be realized in other ways, for example, a rotatable structure with a preset water channel opening is arranged at the water outlet 21 of the water diversion pipeline in an outward protruding way, and then the first end of the sprayer 1 is fixedly connected with the rotatable structure, so that the sprayer 1 rotates by taking the sprayer as a shaft. In addition, the sprayer 1 with the second end closed design can be adopted, so that a plug structure is omitted, and the installation structure is simpler and easier to operate.
In the embodiment, the rotation axis of the sprayer 1 is perpendicular to the side wall of the inner container cavity, so that the sprayer 1 is horizontally arranged in the inner container cavity of the dish washer; preferably, the sprayer 1 is connected to the symmetrical central line of the corresponding side wall, and the symmetrical central line is perpendicular to the bottom surface of the liner cavity; more preferably, the sprayer 1 is connected to the geometric center of the corresponding side wall.
In this embodiment, since the spray water of the sprayer 1 covers the cylinder-like space region with the sprayer 1 as the axis and the spray distance of the water as the radius, the spray water is arranged at the center of the inner container cavity of the dish washer and is axially arranged in parallel, so that the optimal cleaning effect can be achieved.
Example 2
The distinguishing features of this embodiment from embodiment 1 are that:
in this embodiment, the orientation of the spout 11 coincides with a tangent line passing through the spout 11 in the circumferential direction of the sprinkler 1.
In this embodiment, in order to better improve the effect of jet propulsion rotation, the water jet direction is arranged tangentially to the periphery of the sprayer 1, so that the effect of water jet propulsion on the rotation of the sprayer 1 is further improved.
In this embodiment, the spiral lines formed by arranging the nozzles 11 are not equidistantly arranged, and the intervals between the nozzles 11 arranged at the shorter pitch part on the spiral line are smaller than those between the nozzles 11 arranged at the longer pitch part, so that the density of the nozzles 11 in the length direction of the sprayer 1 is uneven.
In this embodiment, when the spiral line formed by the nozzles 11 adopts non-equidistant spiral, the pitch can be lengthened in the area with less bowls, the pitch is increased to reduce the number of the nozzles 11, and the pitch is reduced in the area with concentrated bowls, the pitch is reduced to increase the number of the nozzles 11, so as to improve the overall cleaning effect, and meanwhile, the flushing of unnecessary areas is reduced to control the speed of the backwater water, so that the normal operation of the washing pump is ensured; or a plurality of non-rotatable sprayers 1 are arranged, and different unequally-spaced spiral arrangements are adopted for the spray nozzles 11 of each sprayer 1 according to different positions of the sprayers in the dish-washing machine so as to realize the flushing schemes corresponding to different areas.
