In the description of the present invention, "a plurality" means two or more.

A detailed structure of a spraying system 1 of a dishwasher according to an embodiment of the present invention will be described with reference to fig. 1 to 5.

As shown in fig. 1, a spraying system 1 of a dishwasher according to an embodiment of the present invention includes a water supply assembly 10, a spray arm 30 seat 20, a spray arm 30 and an auxiliary spraying member 40, the water supply assembly 10 having a water inlet 130 and a plurality of water outlets 140, the water supply assembly 10 for guiding a water flow from the water inlet 130 toward the plurality of water outlets 140, the spray arm 30 seat 20 connected at the water outlets 140, the spray arm 30 pivotably provided on the spray arm 30 seat 20, the spray arm 30 provided with a main spraying hole 330. The auxiliary injection member 40 is connected to the water outlet 140, and the auxiliary injection member 40 is provided with auxiliary injection holes 430 for injecting water toward corners of the basket in the dishwasher.

It will be appreciated that, in operation of the spray system 1, a water flow enters the water supply assembly 10 from the water inlet 130 and flows under the guidance of the water supply assembly 10 to the water outlet 140, and the water outlet 140 is connected with the spray arm 30 and the auxiliary spray member 40, the spray arm 30 spraying the washing water toward the central portion of the basket in the dishwasher, and the auxiliary spray member 40 spraying the washing water toward the corners of the basket. Therefore, the spraying system 1 of the embodiment of the invention can improve the washing effect on the corners of the bowl and basket under the condition of ensuring the washing effect of the spraying arm 30.

According to the spraying system 1 of the dishwasher of the embodiment of the present invention, since the auxiliary spraying member 40 for spraying the washing water toward the corner of the basket is provided, the washing capability of the spraying system 1 to the corner of the basket is improved, the spraying and washing range of the spraying system 1 is expanded, and the user satisfaction is improved.

It should be added that the bowl basket is formed in a square shape generally, and the spray arm 30 is positioned above the middle portion of the bowl basket generally, in some embodiments of the present invention, the auxiliary spray member 40 is formed in a plurality, and the plurality of auxiliary spray members 40 are distributed at both ends of the spray arm 30. Thereby, the cleaning capacity of the injection system 1 is further ensured.

In some embodiments, the spraying system 1 of the dishwasher further comprises a plurality of control valves (not shown) for controlling the water outlet of the plurality of water outlets 140 in a one-to-one correspondence. It is understood that a plurality of control valves may control the water output from the plurality of water outlets 140 in a one-to-one correspondence. Therefore, when the spray arm 30 and the auxiliary spray member 40 are plural, a plurality of control valves connected thereto may be controlled to achieve whether the spray arm 30 and the auxiliary spray member 40 spray water. That is, the control valves corresponding to the water outlets 140 realize the water spraying control of the spray arm 30 and the auxiliary spraying member 40, so that the spraying system 1 can spray water toward a certain area of the bowl basket according to the actual washing requirement, and the spraying system 1 of the embodiment of the present invention has the function of spraying water in a partitioned manner.

In some embodiments, as shown in fig. 1, the water supply assembly 10 includes a water riser 110, the water riser 110 is vertically disposed, the top of the water riser 110 is connected to one spray arm 30 base 20, a plurality of branches 120 are disposed at the middle of the water riser 110, the plurality of branches 120 are vertically spaced apart, and each branch 120 is provided with a plurality of water outlets 140 for connecting the auxiliary spray members 40. It can be understood that the plurality of branches 120 are distributed at intervals along the extending direction of the water lift pipe 110, and each branch 120 is connected with a plurality of water outlets 140 for connecting the auxiliary injection member 40, that is, the auxiliary injection members 40 are arranged on two sides along the extending direction of the water lift pipe 110, so that the injection range of the auxiliary injection members 40 can include all the edges of the bowl basket, the injection dead angle of the injection system 1 is further reduced, and the cleaning effect of the injection system 1 is ensured.

In some embodiments, as shown in fig. 1 and 5, the auxiliary injection member 40 includes a horizontal plate 410 and a vertical plate 420 which are perpendicular to each other, and a plurality of auxiliary injection holes 430 are provided on surfaces of the horizontal plate 410 and the vertical plate 420 facing each other, where each of the auxiliary injection holes 430 has a diameter d, and d satisfies the following relation: d is more than or equal to 1.5mm and less than or equal to 2.5 mm. It is understood that the excessively large diameter of the sub spray holes 430 causes the spray water flow to be large, thereby increasing the washing noise. And the small diameter of the auxiliary injection hole 430 may cause the poor injection effect of the auxiliary injection member 40. Therefore, the washing noise can be controlled and the washing effect can be ensured by unloading the diameter of the sub nozzle 430 by 1.5mm-2.5 mm. Of course, the diameter of the secondary nozzle hole 430 may be adjusted according to actual needs and is not limited to the above range.

It should be noted that the auxiliary spraying member 40 includes a horizontal plate 410 and a vertical plate 420 which are perpendicular to each other, that is, the water flow sprayed by the auxiliary spraying member 40 is horizontal and vertical, which greatly ensures the cleaning effect for the corners of the washing chamber.

In some specific embodiments, as shown in fig. 3-4, the width of the transverse plate 410 is equal to the width of the vertical plate 420, the length of the intersection line L1 of the transverse plate 410 and the vertical plate 420 is the width b, and b satisfies the relationship: b is more than or equal to 30mm and less than or equal to 120mm, the length of the transverse plate 410 is a, and a satisfies the relation: a is more than or equal to 30mm and less than or equal to 80mm, the length of the vertical plate 420 is h, and h satisfies the relation: h is more than or equal to 50mm and less than or equal to 100 mm.

It should be noted that the length and width of the horizontal plate 410 and the vertical plate 420 are determined according to the size of the inside of the washing chamber of the dishwasher and the distance between two adjacent branches 120, and the parameter ranges of a, b and h are only preferable ranges set for the specific situation of one embodiment of the present invention, and are not absolute limits on the length and width of the horizontal plate 410 and the vertical plate 420. That is, in other embodiments of the present invention, the length and width dimensions of the horizontal plate 410 and the vertical plate 420 can be set arbitrarily according to practical situations.

In some specific embodiments, the thickness of the cross plate 410 is d1, and the d1 satisfies the relationship: d1 is more than or equal to 4mm and less than or equal to 10mm, the thickness of the vertical plate 420 is d2, and d2 satisfies the relation: d2 is more than or equal to 4mm and less than or equal to 10 mm. It can be understood that, since the sub injection holes 430 are formed on both the horizontal plate 410 and the vertical plate 420, the horizontal plate 410 and the vertical plate 420 should be formed in a hollow structure. It should be noted that, when the horizontal plate 410 and the vertical plate 420 form a hollow structure, if the thickness of the horizontal plate 410 and the vertical plate 420 is too thick, the inside of the horizontal plate 410 and the vertical plate 420 is too large, so that the impact force of the water flow sprayed from the auxiliary injection holes 430 is small, the cleaning capability of the water flow sprayed from the auxiliary injection holes 430 is reduced to a certain extent, and the thickness of the horizontal plate 410 and the vertical plate 420 is too small, so that the processing difficulty is increased, and the production cost is increased. Therefore, the thicknesses of the transverse plate 410 and the vertical plate 420 are controlled to be 4-10 mm, so that the water flow impact force sprayed from the auxiliary spray holes 430 is large, the processing technology of the transverse plate 410 and the vertical plate 420 is simplified, and the production cost is reduced.

Of course, it should be additionally noted that the thickness d1 of the horizontal plate 410 and the thickness d2 of the vertical plate 420 can be selected according to practical situations, and are not limited to the above parameters.

In some embodiments, as shown in fig. 5, the connection pipe 440 is provided on the rear surface of the riser 420, and the auxiliary injection member 40 is communicated with the water outlet 140 through the connection pipe 440. The connection pipe 440 is provided above the vertical plate 420 to facilitate the connection of the auxiliary spraying member 40 to the water outlet 140, but the connection pipe 440 may be provided on the rear surface of the horizontal plate 410.

In some more specific embodiments, the diameter of the connecting tube 440 is D, which satisfies the relationship: d is more than or equal to 8mm and less than or equal to 15mm, the distance between the central axis of the connecting pipe 440 and the lower surface of the transverse plate 410 is h0, h0 satisfies the relation that h0/D is more than or equal to 1.2, and the central axis of the connecting pipe 440 is located at the width center of the vertical plate 420. It can be understood that the connection pipe 440 with an excessively large or small diameter may have an adverse effect on the injection effect of the secondary injection holes 430 on the horizontal plate 410 and the vertical plate 420, and the injection effect of the secondary injection holes 430 can be ensured by controlling the diameter of the connection pipe 440 within a range of 8mm-15 mm. The specific position of the connection pipe 440 also affects the spraying effect of the secondary nozzle holes 430, for example, if the central axis of the connection pipe 440 is deviated from the width center of the vertical plate 420, the distribution of the flow distribution inside the horizontal plate 410 and the vertical plate 420 may be uneven, so that the spraying water flow of the secondary nozzle holes 430 is uneven, thereby affecting the cleaning effect. Too far from the bottom surface of the connecting tube 440 with the horizontal plate 410 may cause uneven spraying of the secondary nozzle 430 on the horizontal plate 410, and too short of the distance may increase the risk of water leakage. Therefore, in order to ensure the injection effect of the transverse plate 410 and the sub injection holes 430 on the vertical plate 420 and the sealing effect of the connection pipe 440 and the vertical plate 420, the distance h0 between the central axis of the connection pipe 440 and the lower surface of the transverse plate 410 can be controlled between 1.2 times of the diameter of the connection pipe 440 and 1.5 times of the diameter of the connection pipe 440, and the central axis of the connection pipe 440 coincides with the width center of the vertical plate 420.

In addition, it should be noted that the connection pipe 440 serves only to connect the auxiliary spouting member 40 and the water outlet 140, and the position, size and dimension of the connection pipe 440 are only exemplary and are not intended to make a specific limitation on the specific shape of the connection pipe 440. That is, the connection pipe 440 may be provided at any position and in any shape according to actual needs.

In some alternative embodiments, as shown in fig. 3, the long side of the horizontal plate 410 is the long transverse side L2, the long side of the vertical plate 420 is the long vertical side L3, and the long transverse side L2, the long vertical side L3, and the intersecting line L1 of the horizontal plate 410 and the vertical plate 420 intersect at a point. In the extending direction of the intersecting line L1, two rows of auxiliary nozzle holes 430 are arranged on the transverse plate 410 at intervals, the distance between two rows of auxiliary nozzle holes 430 is b2, and the distance between one row of auxiliary nozzle holes 430 adjacent to the transverse long side L2 and the transverse long side L2 is b 1; in the extending direction of the intersecting line L1, three rows of spaced auxiliary nozzle holes 430 are arranged on the vertical plate 420, the distance between the auxiliary nozzle hole 430 adjacent to the vertical long side L3 and the vertical long side L3 is b3, the distance between the auxiliary nozzle hole 430 in the middle row and the auxiliary nozzle hole 430 in the row adjacent to the vertical long side L3 is b4, and the distance between the auxiliary nozzle hole 430 in the middle row and the auxiliary nozzle hole 430 in the other row is b 5; and, b1, b2, b3, b4 and b5 satisfy the relation: (b-3d) > (b3+ b4+ b5) > (b1+ b2) > (b3+ b4) > b1 > (b3+ d).

First, in order to distinguish the two rows of the sub nozzle holes 430 in the horizontal plate 410 from the three rows of the sub nozzle holes 430 in the vertical plate 420, the sub nozzle hole 430 in the horizontal plate 410 at a distance B1 from the lateral side L2 is referred to as a B1 row of the sub nozzle holes 430, and the sub nozzle hole 430 in the B1 row at a distance B2 is referred to as a B2 row of the sub nozzle holes 430. One end of the vertical plate 420, which is separated from the vertical side L3 by B3 and called B3 row auxiliary injection holes 430, which is separated from the B3 row auxiliary injection holes 430 by B4 and called B4 row auxiliary injection holes 430, which is separated from the B4 row auxiliary injection holes 430 by B5 and called B5 row auxiliary injection holes 430, and the intersection line L1 of the horizontal side L2, the vertical side L3, the horizontal plate 410 and the vertical plate 420 is called an inner end, and the other end is called an outer end.

It is understood that, since B3+ B4+ B5 > B1+ B2, the B5 rows of sub nozzle holes 430 are located outside the B2 rows of sub nozzle holes 430 in the extending direction of the intersection line L1; since B1+ B2 > B3+ B4, the B2 rows of sub nozzle holes 430 are located outside the B4 rows of sub nozzle holes 430 in the extending direction of the intersection line L1; since B3+ B4 > B1, the B4 rows of sub nozzle holes 430 are located outside the B1 rows of sub nozzle holes 430 in the extending direction of the intersection line L1; since B1 > B3+ d, the B1 rows of sub nozzle holes 430 are located outside the B3 rows of sub nozzle holes 430 in the extending direction of the intersecting line L1; since B-3d > B3+ d, that is, B-B3 > 4d, the centers of the B5 rows of secondary nozzle holes 430 are still spaced from the outer edges of the risers 420.

In summary, in the extending direction of the intersection line L1, the B3 rows of auxiliary injection holes 430, the B1 rows of auxiliary injection holes 430, the B4 rows of auxiliary injection holes 430, the B2 rows of auxiliary injection holes 430, and the B5 rows of auxiliary injection holes 430 are distributed at a time, that is, the vertical plate 420 and the auxiliary injection holes 430 on the horizontal plate 410 are distributed at intervals, so that the injection range of the auxiliary injection holes 430 is expanded to a certain extent, and the cleaning dead angle of the injection system 1 is further reduced. Of course, the arrangement of the auxiliary nozzle holes 430 is not limited to the above description, and may be adjusted according to actual conditions.
