Summary of the invention

The purpose of this utility model is to provide a kind of spray arms for dish-washing machine, and quality of spraying water is high, and additionally providing makes With the dish-washing machine of the spray arm, cleaning effect is good.

In order to achieve the above object, the utility model adopts the following technical solution: a kind of spray arm for dish-washing machine is washed Bowl machine includes shell, the liner for placing tableware, respirator, washing pump and the draining pump being connected to water source, the inner bag The sink with heating element is included, the liner at the bottom is equipped with the washing pump and draining pump being connected to sink, the bottom of the liner Wall is equipped with the spray arm being connected to washing pump, and washing pump supplies water to spray arm so that spray arm rotates and to the tableware in liner It is cleaned, the spray arm floor projection is in "~" shape, and spray arm includes upper-part and lower part, and upper-part is equipped with spray Hole, lower component are equipped with connecting tube, surround to form inner cavity between upper-part and lower part, and inner cavity connects connecting tube and spray apertures It is logical, it is integral by secondary operation between upper-part and lower part.

Further, pass through appointing in ultrasonic welding, hot melt, clamping, screw connection between the upper-part and lower part A kind of mode of anticipating carries out secondary operation.

Further, the bottom wall of the liner is additionally provided with the water supplying pipe being connected to connecting tube, and the inner cavity of the water supplying pipe is cut Area is greater than the sum of spray apertures sectional area.

Further, the spray arm 4 in the opening of connecting tube along place be equipped with support rim, the support rim and The upper of water supplying pipe is arranged along fitting.

Further, the outer wall of the water supplying pipe is equipped with the card muscle of annular, and the spray arm, which is equipped with, to be cooperated with card muscle Elastic buckle, Elastic buckle can be circumferentially rotated with respect to card muscle when spray arm rotates, the gap between the card muscle and Elastic buckle For W1,0mm < W1 < 3mm.

Further, the outer wall of the connecting tube is equipped with limit rib, is equipped between the limit rib and the inner wall of water supplying pipe Gap W2,0.2mm < W2 < 0.4mm.

Further, the spray apertures are equipped with multiple and length direction intervals along spray arm and are arranged.

Further, the injection direction of the spray apertures is obliquely installed, the injection direction of spray apertures and the angle of horizontal plane It is 3 °~75 °.

Further, multiple drive holes are additionally provided on the side wall of the spray arm, the injection direction of the drive hole is horizontal It is arranged or is obliquely installed.

The utility model also provides a kind of dish-washing machine, including shell, liner and spray arm for placing tableware.

After adopting the above technical scheme, the utility model has the advantages that

1, by keeping spray arm integral by secondary operation by upper-part and lower part, spray arm leakproofness is improved Meanwhile the stability of spray arm configuration is also improved, pressure can be generated in inner cavity when spray arm water spray, to upper-part and lower part Part generates extruding force, and prolonged extruding force can reduce the leakproofness of upper-part and lower part joining place, by secondary operation at Type improves the compactness of upper-part and lower part linking, the efficiency and quality of spray arm water spray is improved, by making spray arm Floor projection is in "~" shape, has not only enhanced the jeting effect of spray arm water flow, but also improve aesthetic appearance.

2, by making upper-part and lower part pass through any one mode in ultrasonic welding, hot melt, clamping, screw connection Secondary operation is carried out, first ensure that the stability of spray arm configuration, and second improves the leakproofness of spray arm, ensure that spray The quality of arm water spray.

3, by making the intracavity section product of water supplying pipe be greater than the sum of spray apertures sectional area, it ensure that the hole of all spray apertures Diameter is respectively less than the aperture of water supplying pipe, ensure that the pressure of each spray apertures water spray, improves the quality of spray arm water spray, further Improve clearly quality.

4, the setting of support rim improves the stability that connecting tube is assemblied on water supplying pipe, enables spray arm steady Fixed rotation, ensure that the stability of spray arm water spray.

5, it by setting limit rib, can prevent connecting tube from tilting, improve the stability of spray arm rotation, limit rib and confession The inner wall of water pipe is equipped with gap W1,0 < W1 < 3mm, can also effectively avoid water supplying pipe on the basis of ensure that connecting tube rotation The water of ejection is oozed out from the gap of water supplying pipe and connecting tube, improves the quality of water spray.When W1 be 0mm when, at this time limit rib with It is contacted between water supplying pipe, the frictional force between limit rib and water supplying pipe makes the blocked rotation of spray arm, greatly reduces spray arm Rotation efficiency, reduce spray arm water spray quality.

6, it is circumferentially rotated by Elastic buckle with respect to card muscle, realizes that spray arm rotates on water supplying pipe, to realize spray arm Rotary water jet, Elastic buckle can facilitate the disassembly and installation of spray arm, can install difference additional according to different cleaning demands The spray arm of size and water outlet bore, improves the practicability of dish-washing machine, by making the gap W1 between card muscle and Elastic buckle, 0 < W1 < 3mm realizes water supplying pipe to when connecting tube water supply, and water is not easy to overflow from the gap of water supplying pipe and connecting tube, improves The efficiency and quality of spray arm water outlet.When W is 0mm, contacted between card muscle and Elastic buckle at this time, so that the rotation of spray arm Resistance is excessive when turning, and seriously reduces the rotation efficiency of spray arm, when W is greater than 3mm, at this time between card muscle and Elastic buckle Gap is excessive, and when water supplying pipe supplies water to connecting tube, water overflows easily from the gap of water supplying pipe and connecting tube, reduces spray arm Water spray quality.

7, by making spray apertures along setting is spaced on spray arm length direction, so that the water energy that spray apertures spray is enough more It is uniformly ejected on object to be cleaned, improves the quality of cleaning.

8, by being obliquely installed the injection direction of spray apertures, the injection direction of spray apertures and the angle of horizontal plane be 3 °~ 75 °, the water for increasing water spray area, while tilting ejection can speed up spray arm rotation, improve the efficiency of spray arm water spray, And the injection direction of spray apertures is obliquely installed and also avoids the water of spray apertures and be directly injected on adjacent spray arm, improves The efficiency of spray arm water spray.When the injection direction angle with horizontal plane of spray apertures is less than or equal to 3 °, at this time due to spraying direction Angle with horizontal plane is too small, and the water for causing spray apertures to spray can not be injected on part to be cleaned, reduces cleaning efficiency and quality. When the injection direction angle with horizontal plane of spray apertures is greater than 75 °, the water that spray apertures spray at this time can be to the rotation of adjacent spray arm Turn to adversely affect, the efficiency of spray arm rotation is reduced, to reduce the efficiency and quality of cleaning.

9, it by the way that drive hole is arranged on the side wall of spray arm, is horizontally disposed with by the injection direction of drive hole or inclination is set It sets, spray arm rotation is driven by the water that drive hole sprays, improves the efficiency of spray arm rotation.

10, using the dish-washing machine of spray arm disclosed in the utility model, effectively increase dish-washing machine cleaning efficiency and Quality.
