The spray arm assembly 1 according to the dish-washing machine of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 5, comprise fixed gear 10, main jet arm 20, moving gear 30 and secondary spray arm 40 according to the spray arm assembly 1 of the dish-washing machine of the embodiment of the present invention.
Fixed gear 10 is provided with the water inlet 101 be communicated with water inlet equipment.Main jet arm 20 is connected with fixed gear 10 and central axis around fixed gear 10 can pivotable.There is in main jet arm 20 the first spray chamber 201 be communicated with water inlet 101.The outer surface of main jet arm 20 is provided with the thrust hole 203 and multiple first spray orifice 202 that are communicated with the first spray chamber 201.
Moving gear 30 is connected with main jet arm 20, and under the reaction thrust effect of thrust hole 203 injection water, moving gear 30 can with main jet arm 20 synchronous axial system, and the central axis namely around fixed gear 10 can pivotable.In the process of moving gear pivotable, moving gear 30 and fixed gear 10 engaged transmission, make moving gear 30 can also realize the pivotable of the central axis around self.Secondary spray arm 40 is connected with moving gear 30 and follower gear 30 is synchronized with the movement, and be limited with the second spray chamber 401 be communicated with water inlet 101 in secondary spray arm 40, the outer peripheral face of secondary spray arm 40 is provided with multiple the second spray orifice 402 be communicated with the second spray chamber 401.
According to the spray arm assembly 1 of the dish-washing machine of the embodiment of the present invention, by arranging moving gear 30 and making moving gear 30 engage with fixed gear 10 and be connected with secondary spray arm 40, make secondary spray arm 40 can realize around the pivotable of the central axis along main jet arm 20 and the pivotable around the central axis along fixed gear 10, namely secondary spray arm 40 can realize Two Dimensional Rotating motion, multiple second spray orifices 402 on secondary spray arm 40 constantly can be shifted one's position along with secondary spray arm 40, thus the angle of injection water can ceaselessly be changed, eliminate washing dead angle, shorten wash time and the rate of cleaning raising; Meanwhile, spray arm is made up of multiple points of body components such as main jet arm 20, secondary spray arm 40 and moving gears 30, and not only easy to assembly but also can effectively reduce manufacture difficulty, maintain and replace also facilitates, and cost reduces.
Specifically, as depicted in figs. 1 and 2, spray arm assembly 1 comprises fixed gear 10, moving gear 30, main jet arm 20 and secondary spray arm 40.Fixed gear 10 is motionless, and fixed gear 10 can play connection and supporting role, and spray arm assembly 1 is connected with miscellaneous part.Secondary spray arm 40 is connected with main jet arm 20 by moving gear 30, and main jet arm 20 can drive moving gear 30 and secondary spray arm 40 to rotate.
Moving gear 30 engages with fixed gear 10, fixed gear 10 has the circle tooth along horizontal distribution, moving gear 30 has the circle tooth along vertically distribution, moving gear 30 is with when moving under the engagement of fixed gear 10, moving gear 30 gets final product rotation, also can revolve round the sun, namely also revolve round the sun around fixed gear 10 while rotation.Specifically, moving gear 30 certainly transfer the pivotable of moving gear 30 around the central axis along fixed gear 10 to, as shown in left arrow in Fig. 1.The revolution of moving gear 30 be moving gear 30 around the pivotable along the central axis of self, as shown in right side arrow in Fig. 1.
When spray arm assembly 1 in working order time, current can be ejected in thrust hole 203 on main jet arm 20, under the promotion of reaction force, main jet arm 20 can rotate in the plane of level around the central axis along fixed gear 10, simultaneously moving gear 30 under the drive of main jet arm 20 with main jet arm 20 synchronous rotary, secondary spray arm 40 under the drive of moving gear 30 also with main jet arm 20 synchronous rotary.Now, the spray arm be made up of main jet arm 20, secondary spray arm 40 and moving gear 30 can be implemented in the rotation in the plane of level.
Wherein, when moving gear 30 moves under the drive of main jet arm 20, moving gear 30 engages with fixed gear 10 the moving situation defining moving gear 30, and namely moving gear 30 is while rotating along the central axis around fixed gear 10, and moving gear 30 achieves around the pivotable along the central axis of self.Thus, also there is the pivotable around the central axis along moving gear 30 in secondary spray arm 40 under the drive of moving gear 30.Now, spray arm not only can be implemented in the rotation of the plane of level, and a part for spray arm can also realize the rotation in vertical plane.Spray arm achieves Two Dimensional Rotating motion, and rate of cleaning improves.
It should be noted that, because moving gear 30 is connected with main jet arm 20, secondary spray arm 40 is connected with moving gear 30.Therefore, spray arm is as a whole structural member (being namely integrally formed part) not, but is assembled by multiple points of body components.Main jet arm 20 is a split part, and whole secondary spray arm is originally divided into again two split parts: secondary spray arm 40 and moving gear 30.
For structure for the relatively simple and structural member that size is relatively little, the structure be integrally formed can be better than the structure that split is formed usually.But because spray arm is formed as strip usually, and extend longer dimension, if spray arm is formed as one part, the mould needed during fabrication can be very large, and manufacture difficulty strengthens and parts more easily produce flaw, and be not easy to transport, cost is high simultaneously.
And when being designed to by spray arm assemble by multiple split part the structure formed, the size of multiple split part is significantly less than the size of whole spray arm, particularly length can reduce significantly.Thus, the die size of needs also can reduce, and manufacture difficulty reduces, and workmanship promotes, and is also convenient to transport simultaneously, assembles also simpler.Further, wherein when some split parts damage, only need change the parts of damage, and without the need to being replaced by whole spray arm, cost reduces greatly.Meanwhile, different secondary spray arms 40 can also be selected as required to match with main jet arm 20, the replacement cost of spray arm assembly 1 reduces, and the structure of spray arm assembly 1 is more diversified, can meet more washing and require and environmental aspect requirement.
Here, it should be noted that, the scheme original whole secondary spray arm being divided into two split parts is not simple structure and quantitative fractionation.After whole secondary spray arm is divided into two secondary spray arms 40 and moving gear 30 by this, make whole secondary spray arm can be divided into the different structural member of multiple function, secondary spray arm 40 uses as the parts of injection water, and moving gear is then as connecting the connector of main jet arm 20 and secondary spray arm 40 and using being converted to the parts adding the converting motion state of rotation that revolve round the sun.
When eject request changes, different secondary spray arms 40 can be changed; When there is different requirements to the motion state of secondary spray arm 40, then replacing moving gear that can be in good time.Such as, the gear with the different number of teeth can be changed, to make secondary spray arm 40, there is different autorotation speeds.
Meanwhile, in use, the junction between parts is more easily damaged usually, particularly has and transmits power actuated junction.In above structure, moving gear 30 is connected with three parts simultaneously: fixed gear 10, main jet arm 20, secondary spray arm 40.Moving gear 30 is relatively easy to be damaged, and is manufactured as a split part separately by moving gear 30, can so that change, and manufacture also relatively more easy.
In brief, according to the spray arm assembly 1 of the embodiment of the present invention, spray arm can realize by the change of one dimension rotation to Two Dimensional Rotating, and rate of cleaning improves; And spray arm is no longer one-body molded, wherein secondary spray arm 40 can be made up of two split parts, and manufacturability improves, cost reduces.
Be understandable that, moving gear 30 can adopt various ways to be connected with secondary spray arm 40.Such as, as shown in Figure 1 to Figure 3, moving gear 30 can be threaded with secondary spray arm 40.Specifically, moving gear 30 is provided with internal thread, and secondary spray arm 40 is provided with the external screw thread with screw-internal thread fit.Certainly, also internal thread can be located on moving gear 30, external screw thread be located on fixed gear 10.Again such as, in other examples of the present invention, moving gear 30 with secondary spray arm 40 for clamping is connected.
As shown in Figure 3, in examples more of the present invention, moving gear 30 comprises gear part 31, first connecting portion 32 and the second connecting portion 33.First connecting portion 32 is connected with gear part 31, and the second connecting portion 33 is connected with the first connecting portion 32.In other words, the first connecting portion 32 is connected between gear part 31 and the second connecting portion 33.As shown in Figure 1 to Figure 3, gear part 31 engages with fixed gear 10 and is connected.First connecting portion 32 to be set on main jet arm 20 and to be connected pivotly with main jet arm 20.Second connecting portion 33 is connected with secondary spray arm 40, specifically can adopt and be threaded or clamping etc.
Thus, gear part 31 can play the effect be connected with a joggle with fixed gear 10, and the first connecting portion 32 can play the effect be connected with main jet arm 20, and the second connecting portion 33 can play the effect be connected with secondary spray arm 40, each parts division of labor is clear and definite, can manufacture targetedly according to needing separately.
Wherein, the second connecting portion 33 can be connected with main jet arm 20 clamping.Specifically, the inner peripheral surface of the first connecting portion 32 is provided with buckle muscle 321.The outer peripheral face of main jet arm 20 is provided with buckle 21.When connecting main jet arm 20 with moving gear 30, buckle muscle 321 and buckle 21 clamping mutually, easy to assembly and be connected firmly.
As shown in Figure 4, buckle muscle 321 can be formed as on inner peripheral surface that a circle is located at the first connecting portion 32 and the convex tendon extended along the radial direction of the first connecting portion 32 to the central axis of the first connecting portion 32.As shown in Figure 5, buckle 21 can be formed as the projection that extends to the central axis away from main jet arm 20 on outer peripheral face that a circle is located at main jet arm 20 and along the radial direction of main jet arm 20.Advantageously, as shown in Figure 3, the mating surface that projection and convex tendon only support mutually can be formed as inclined-plane respectively, to reduce the difficulty of assembling while ensureing snap effect.
As shown in Figure 2, one end of main jet arm 20 can extend beyond the junction of moving gear 30 and secondary spray arm 40.Thus, main jet arm 20 can strengthen spray arm assembly 1 in the rigidity of moving gear 30 with the connecting portion place of secondary spray arm 40, and make the bonding strength of spray arm assembly 1 stronger, spray arm assembly 1 not easily disintegrates.
Wherein, when gap appears in the junction between main jet arm 20 and moving gear 30 and between secondary spray arm 40 and moving gear 30, the water in the second spray chamber 401 is easy to flow out in gap, causes unnecessary the leaking of spray arm assembly 1, weaken injection water, reduce cleaning function.In order to reduce the current leakage problem of spray arm assembly 1, the outer peripheral face of one end of main jet arm 20 can arrange anti-leak muscle 22, anti-leak muscle 22 can extend to the inner peripheral surface of secondary spray arm 40 from the outer peripheral face of main jet arm 20, to stop that the water in the second spray chamber 401 flow to the gap of junction.
Meanwhile, consider that moving gear 30 and secondary spray arm 40 have rotary motion relative to main jet arm 20, therefore, in order to ensure the smooth and easy rotation of spray arm and moving gear 30, anti-leak muscle 22 only should not support with the inner peripheral surface of secondary spray arm 40.Preferably, anti-leak muscle 22 can be matched in clearance with the inner peripheral surface of secondary spray arm 40, while preventing current from revealing, can ensure the smooth and easy rotation of secondary spray arm 40 and moving gear 30.
