The spraying arm of dish washer device that this utility model embodiment provides, being preferably applied to wash inner chamber is in rectangular-shaped cabinet type household dish-washing machine, and so, beneficially increasing degree ground improves the clean effect of cabinet type household dish-washing machine.Of course, the spraying arm of dish washer device that this utility model embodiment provides, however it is not limited to being applied to wash inner chamber is in rectangular-shaped cabinet type household dish-washing machine.
Specifically, spray arm device, middle spray arm device and lower spraying arm device it is provided with in dish-washing machine, upper spray arm device, middle spray arm device and lower spraying arm device are respectively arranged in the washing top of inner chamber, middle part and bottom, each hole for water spraying on upper spray arm device, middle spray arm device and lower spraying arm device is towards difference, as: the hole for water spraying of upper spray arm device be down, the hole for water spraying of lower spraying arm device be upward, above-mentioned spraying arm of dish washer device is lower spraying arm device；Of course, in concrete application, upper spray arm device, middle spray arm device and lower spraying arm device all can use above-mentioned spraying arm of dish washer device, or, upper spray arm device, middle spray arm device and lower spraying arm device also only one of which or two can use above-mentioned spraying arm of dish washer device, during specific design, design can be optimized according to real needs and manufacturing cost etc..
In the present embodiment, the operation principle of spraying arm of dish washer device is as follows: washings flow into from spray arm seat 1 and swing in spray arm 2, it is then divided into two parts flowing, a part directs out injection from swing spray arm 2 and is rinsed tableware, another part is then from swinging in spray arm 2 in entrance rotation spray arm 3, and final outwards injection from rotation spray arm 3 is rinsed tableware.And rotation spray arm 3 can be driven to carry out horizontal revolving motion the counteracting force rotating spray arm 3 applying from the washings rotating outwards injection spray arm 3, now, first bevel gear 41 horizontally rotates together along with rotation spray arm 3, and the second bevel gear 42 can be driven to horizontally rotate together；And the horizontal rotation of the second bevel gear 42 can drive third hand tap gear 431 to do vertical rotary motion, recessed spherical shell 432 does vertical rotary motion together along with third hand tap gear 431, keep contacting owing to being installed on the recessed shell end face 4322 of the roller 44 and recessed spherical shell 432 swung on spray arm 2, therefore, rotation along with recessed spherical shell 432, roller 44 can roll on recessed shell end face 4322 relatively, thus can order about swing spray arm about 2 and swing back and forth.
Wherein, the concrete swing process swinging spray arm 2 is: as shown in Figure 8 and Figure 9, before swing, swing spray arm 2 in an intermediate position, the most vertically rotary motion along with recessed spherical shell 432, swing spray arm 2 to start to swing to the right from the centre position shown in Fig. 8 and Fig. 9, until being rocked to the low order end position shown in Figure 10 and Figure 11；Afterwards along with the continuation vertically rotary motion clockwise of recessed spherical shell 432, swing spray arm 2 and start backswing, i.e. start to swing the most to the left, continue to swing to the left behind the centre position shown in Figure 12 and Figure 13, until being rocked to the high order end position shown in Figure 14 and Figure 15；Afterwards along with the continuation vertically rotary motion clockwise of recessed spherical shell 432, swing spray arm 2 and start backswing again, i.e. start to swing the most to the right, continue to swing to the right behind the centre position shown in Fig. 8 and Fig. 9, swing the most again and again.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent or improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
