Description

一种洗碗机喷淋臂连接结构及洗碗机Dishwasher spray arm connecting structure and dishwasher 技术领域Technical field
本发明涉及一种洗碗机,特别涉及一种洗碗机喷淋臂的连接结构,属于洗碗机技术领域。The invention relates to a dishwasher, in particular to a connection structure of a dishwasher spray arm, belonging to the technical field of dishwashers.
背景技术Background technique
洗碗机是利用喷嘴喷射高压洗涤水对餐具进行清洗的装置,洗碗机一般包括形成清洗室的洗碗机内胆,在内胆的前方具有餐具投入口,在餐具投入口处设置门体,在清洗室内设置有餐具搁架、喷淋装置等。The dishwasher is a device for cleaning the tableware by spraying high-pressure washing water with a nozzle. The dishwasher generally includes a dishwasher liner forming a cleaning chamber, a tableware input port in front of the inner liner, and a door body at the input port of the tableware. A dish rack, a shower device, and the like are provided in the washing chamber.
为了达到较理想的清洗效果,现有的安装在洗碗机内的喷淋装置一般为可旋转的喷淋臂,在喷淋臂上开设多个喷淋孔,喷淋臂可旋转地连接在内胆本体上,喷淋臂与水路连通,水路中的水经过喷淋臂上的喷淋孔喷出清洗放置在内胆内的餐具。In order to achieve a better cleaning effect, the existing sprinkler installed in the dishwasher is generally a rotatable spray arm, and a plurality of spray holes are opened on the spray arm, and the spray arm is rotatably connected On the inner body of the liner, the spray arm communicates with the waterway, and the water in the waterway is sprayed through the spray hole on the spray arm to clean the tableware placed in the inner tank.
现有的喷淋臂与内胆本体之间的连接结构是通过喷淋臂环将喷淋臂与内胆本体连接,喷淋臂套装在喷淋臂环的外侧,喷淋臂环套装在内胆本体的外侧并绕着内胆本体旋转。设置喷淋臂环的目的是加大喷淋臂与内胆本体之间的接触面积,保证转动时不出现上下扭动或左右扭动的情况,降低运转时的阻力。但该种连接结构在实现上仍然存在以下问题,一是洗碗机喷淋臂运行时,喷淋臂与喷淋臂环之间、喷淋臂环与内胆本体之间在转动时仍然存在上下与左右的活动,这样都会导致喷淋臂的转动受阻,而且中间的喷淋臂环由于安装的限制只能做成是两个拼在一块的结构,两个件之间通过粘贴或卡扣的方式固定连接在一起,这样拼接处便会存在不光滑点,而且依靠倒扣进行锁住,使拆装困难。The connection structure between the existing spray arm and the inner body of the liner is to connect the spray arm to the inner body of the bladder through a spray arm ring, and the spray arm is set on the outer side of the spray arm ring, and the spray arm ring is set inside. The outer side of the bladder body rotates around the inner body of the bladder. The purpose of setting the spray arm ring is to increase the contact area between the spray arm and the body of the liner, so as to ensure that there is no up and down twisting or twisting left and right when rotating, and the resistance during operation is reduced. However, the connection structure still has the following problems in implementation. First, when the spray arm of the dishwasher is running, the spray arm and the spray arm ring are still in rotation between the spray arm ring and the inner body of the liner. Up and down and left and right activities, this will cause the rotation of the spray arm to be blocked, and the spray arm ring in the middle can only be made into two pieces together due to the installation restrictions, and the two pieces are pasted or buckled. The way is fixedly connected together, so that there will be a non-smooth point in the splicing place, and it is locked by the reverse buckle, which makes the disassembly and assembly difficult.

在喷淋过程中,从固定部9底部的入水口进入的洗涤水,沿固定座9及导流部8中心的水流通道向上,在水压的作用下,水流向上冲击导流部8的上导流板8a,水流在一定程度上向上顶起上导流板8a,进而顶起导流部8,同时利用同极第一磁铁19和第二磁铁20之间互相排斥的作用抵消水体本身的纵向合力,使上转动面18与下转动面17之间保有一定的间隙,避免上转动面18与下转动面17直接摩擦,使喷淋臂1的转动更加平稳顺畅。该结构省略了现有技术中的喷淋臂环的结构,使喷淋臂1的连接结构更加简单。本实施例中,还可以采用调节喷淋座4入水口的面积,即增加入水口的面积,使入水口的面积大于所有喷淋孔5的出水面积总和,起到降低水体本身纵向合力的作用。During the spraying process, the washing water entering from the water inlet at the bottom of the fixing portion 9 is upward along the water flow passage at the center of the fixing seat 9 and the flow guiding portion 8, and under the action of the water pressure, the water flow impacts upward on the flow guiding portion 8. The deflector 8a, the water flow uplifts the upper baffle 8a to a certain extent, and then lifts up the flow guiding portion 8, while using the mutual repelling between the first magnet 19 and the second magnet 20 to offset the water body itself. The longitudinal force is combined to maintain a certain gap between the upper rotating surface 18 and the lower rotating surface 17, so as to prevent the upper rotating surface 18 from directly rubbing against the lower rotating surface 17, so that the rotation of the spray arm 1 is smoother and smoother. This structure omits the structure of the spray arm ring in the prior art, and the connection structure of the spray arm 1 is made simpler. In this embodiment, it is also possible to adjust the area of the water inlet of the shower seat 4, that is, to increase the area of the water inlet, so that the area of the water inlet is larger than the sum of the water discharge areas of all the spray holes 5, thereby reducing the longitudinal combined force of the water body itself. .
在喷淋臂1下臂板的下表面上围绕开口6设置有向下凸出的止挡21,止挡21呈环形围绕固定部9设置。止挡21与固定部9之间为间隙配合,同样,导流部8在通孔的位置与固定部9之间在水平方向上也为间隙配合。止挡21与固定部9之间的第一间隙22与导流部8与固定部9之间的第二间隙23保持一致,同样增大或减小,本实施例中,则优选控制第一间隙22和第二间隙23均保持在0.2mm,这样可以有效保证导流部8、固定部9与喷淋臂1之间旋转时的上、下同轴性,在转动过程中,即使在上部或下部有较小程度的偏心,第一间隙22和第二间隙23也会起到相互制约的作用,保证喷淋臂1转动时不发生过大的晃动,减小转动时的晃动阻力,进而保证喷淋臂1转动平稳,更不会在运转过程中出现卡阻的现象。On the lower surface of the lower arm plate of the spray arm 1, a downwardly projecting stop 21 is provided around the opening 6, and the stop 21 is arranged annularly around the fixed portion 9. The gap between the stopper 21 and the fixing portion 9 is a clearance fit. Similarly, the flow guiding portion 8 is also gap-fitted in the horizontal direction between the position of the through hole and the fixing portion 9. The first gap 22 between the stop 21 and the fixing portion 9 is consistent with the second gap 23 between the flow guiding portion 8 and the fixing portion 9, and is also increased or decreased. In this embodiment, the first control is preferably controlled. Both the gap 22 and the second gap 23 are maintained at 0.2 mm, so that the upper and lower coaxiality when the flow guiding portion 8, the fixing portion 9 and the spray arm 1 are rotated can be effectively ensured, even during the rotation, even in the upper portion Or the lower portion has a small degree of eccentricity, and the first gap 22 and the second gap 23 also play a mutually restricting role, ensuring that the spray arm 1 does not undergo excessive shaking when rotating, and reduces the sway resistance during rotation, thereby further Ensure that the spray arm 1 rotates smoothly, and there is no jamming during operation.
