Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household dishwashers are suitable for most families today. Dishwasher can replace hand washing, freeing people's hands, and is gradually becoming a standard for quality life. match. Compared with traditional hand-washing dishes and chopsticks, dishwashers have the advantages of cleaning, sterilizing, and saving water and labor. In related technologies, dishwashers generally use a spray arm assembly to perform cleaning. Driven by a washing pump, water flows through the rotating spray arm assembly to spray and wash the surface of the tableware. The cleaning effect is consistent with the spray arm design. Closely related, the spraying effect of the existing spray arm assembly is single and the scouring effect is poor, which needs to be improved.
参照图1至图5，本发明第一方面的实施例提出一种应用于洗碗机的喷臂组件，洗碗机通常具有上喷臂组件及下喷臂组件，分别从上下两个方向对餐具进行冲刷，本发明第一方面实施例的喷臂组件可作为上喷臂组件或者下喷臂组件，下面以下喷臂组件为例进行说明，喷臂组件包括喷臂座100、转轴200、主喷臂300、副喷臂400，喷臂座100用于固定安装在洗碗机上，是喷臂组件的安装基础，喷臂座100在运行中是固定不动的，喷臂组件的中心设置有贯通的中心孔101，转轴200安装在中心孔101中并且能够转动，转轴200的内部设有沿轴向布置的输水通道201，输水通道201贯穿至转轴200的两端，主喷臂300具有安装座310，安装座310固定连接在转轴200的上端，安装座310设置有安装柱311，安装柱311上安装有轴承410，副喷臂400安装在轴承410上，副喷臂400通过轴承410实现转动，副喷臂400的转动轴线与转轴200的轴线相垂直。Referring to Figures 1 to 5, a first embodiment of the present invention proposes a spray arm assembly applied to a dishwasher. The dishwasher usually has an upper spray arm assembly and a lower spray arm assembly, facing each other from up and down directions respectively. To wash the tableware, the spray arm assembly of the first embodiment of the present invention can be used as an upper spray arm assembly or a lower spray arm assembly. The lower spray arm assembly will be described below as an example. The spray arm assembly includes a spray arm base 100, a rotating shaft 200, a main The spray arm 300, the auxiliary spray arm 400, and the spray arm base 100 are used to be fixedly installed on the dishwasher and are the installation basis of the spray arm assembly. The spray arm base 100 is fixed during operation. The center of the spray arm assembly is provided with Through the central hole 101, the rotating shaft 200 is installed in the central hole 101 and can rotate. The inside of the rotating shaft 200 is provided with a water conveying channel 201 arranged along the axial direction. The water conveying channel 201 penetrates to both ends of the rotating shaft 200. The main spray arm 300 It has a mounting base 310, which is fixedly connected to the upper end of the rotating shaft 200. The mounting base 310 is provided with a mounting column 311, and a bearing 410 is installed on the mounting column 311. The auxiliary spray arm 400 is installed on the bearing 410, and the auxiliary spray arm 400 passes through the bearing. 410 realizes rotation, and the rotation axis of the auxiliary spray arm 400 is perpendicular to the axis of the rotating shaft 200 .
可以理解的是，主喷臂300的内部形成有第一空腔301，副喷臂400的内部形成有第二 空腔401，安装座310设置有内腔312，第一空腔301和第二空腔401通过内腔312连通输水通道201，主喷臂300上形成有多个连通第一空腔301的第一喷孔302，副喷臂400上形成有多个连通第二空腔401的第二喷孔402，洗涤水路从转轴200的输水通道201输入，分流至主喷臂300的第一空腔301和副喷臂400的第二空腔401，然后从第一喷孔302和第二喷孔402喷出，并对餐具进行喷淋洗涤。It can be understood that a first cavity 301 is formed inside the main spray arm 300, a second cavity 401 is formed inside the auxiliary spray arm 400, the mounting base 310 is provided with an inner cavity 312, the first cavity 301 and the second cavity 301 are formed inside the main spray arm 300. The cavity 401 is connected to the water delivery channel 201 through the inner cavity 312. The main spray arm 300 is formed with a plurality of first nozzle holes 302 connected with the first cavity 301. The auxiliary spray arm 400 is formed with a plurality of second cavity 401 connected with each other. The second nozzle hole 402, the washing water path is input from the water delivery channel 201 of the rotating shaft 200, split to the first cavity 301 of the main spray arm 300 and the second cavity 401 of the auxiliary spray arm 400, and then flows from the first nozzle hole 302 and the second nozzle hole 402 to spray and wash the tableware.
如图1所示，主喷臂300设置有五个第一喷孔302，五个第一喷孔302的方向一致而且是倾斜的，对应于转轴200的旋转方向，从五个第一喷孔302喷出的高速水流冲刷餐具，具有均匀的喷淋效果；副喷臂400设置有五个第二喷孔402，五个第二喷孔402的朝向均为倾斜的，沿远离安装座310的方向，第1个和第2个第二喷孔402的喷射方向一致并且朝向内侧，第3个和第4个第二喷孔402的喷射方向一致并且朝向外侧，第5个的喷射方向为远离转轴200的轴线，当副喷臂400旋转，五个第二喷孔402喷出多种方向的水流，对餐具施加多种方向的冲刷，洗涤效果更佳。As shown in FIG. 1 , the main spray arm 300 is provided with five first nozzle holes 302 . The five first nozzle holes 302 are in the same direction and are inclined. Corresponding to the rotation direction of the rotating shaft 200 , from the five first nozzle holes 302 The high-speed water flow sprayed from 302 washes the tableware and has a uniform spray effect; the auxiliary spray arm 400 is provided with five second spray holes 402, and the directions of the five second spray holes 402 are all inclined, along the direction away from the mounting base 310 direction, the spray directions of the first and second second nozzle holes 402 are consistent and toward the inside, the spray directions of the third and fourth second nozzle holes 402 are consistent and toward the outside, and the spray direction of the fifth second nozzle hole 402 is away from each other. When the auxiliary spray arm 400 rotates along the axis of the rotating shaft 200, the five second nozzles 402 spray out water flow in multiple directions, thereby scouring the tableware in multiple directions, resulting in a better washing effect.
喷臂组件连接有传动装置500，传动装置500包括中心齿轮510、转盘齿轮520以及小齿轮530，中心齿轮510和转盘齿轮520均套装在转轴200的中部，主喷臂300设置有平行于转轴200的第二轴320，第二轴320位于转轴200的外侧，小齿轮530套装于第二轴320。其中，中心齿轮510与喷臂座100一样，是固定不动的，转盘齿轮520能够相对于转轴200自由旋转，小齿轮530能够相对于第二轴320自由旋转，中心齿轮510与转盘齿轮520均啮合于小齿轮530，而且中心齿轮510比转盘齿轮520多一个齿或者少一个齿。应当理解的是，如图6所示，虽然中心齿轮510与转盘齿轮520不同，但是两者的齿距较为接近，而且两者与小齿轮530啮合处仅为2至3个齿，所以中心齿轮510与转盘齿轮520能够同时啮合于小齿轮530，并且实现传动。The spray arm assembly is connected to a transmission device 500. The transmission device 500 includes a center gear 510, a turntable gear 520 and a pinion gear 530. The center gear 510 and the turntable gear 520 are both set in the middle of the rotating shaft 200. The main spray arm 300 is provided with a gear parallel to the rotating shaft 200. The second shaft 320 is located outside the rotating shaft 200, and the pinion 530 is sleeved on the second shaft 320. Among them, the center gear 510 is fixed like the spray arm base 100, the turntable gear 520 can freely rotate relative to the rotating shaft 200, and the pinion gear 530 can freely rotate relative to the second shaft 320. The center gear 510 and the turntable gear 520 both It meshes with the pinion gear 530 , and the center gear 510 has one more tooth or one less tooth than the turntable gear 520 . It should be understood that, as shown in Figure 6, although the center gear 510 is different from the turntable gear 520, their tooth pitches are relatively close, and the meshing point between the two and the pinion gear 530 only has 2 to 3 teeth, so the center gear 510 and the turntable gear 520 can mesh with the pinion gear 530 at the same time and realize transmission.
可以理解的是，转盘齿轮520位于中心齿轮510的上方，靠近副喷臂400，转盘齿轮520的上端面设置有触发部521，触发部521的作用是推动副喷臂400绕安装柱311转动，并使从第二喷孔402喷出的水流方向变化。It can be understood that the turntable gear 520 is located above the center gear 510 and close to the auxiliary spray arm 400. The upper end surface of the turntable gear 520 is provided with a trigger part 521. The function of the trigger part 521 is to push the auxiliary spray arm 400 to rotate around the mounting column 311. And the direction of the water flow sprayed from the second nozzle hole 402 is changed.
可以理解的是，主喷臂300和副喷臂400在喷射水流的反作用力下，带动转轴200旋转，即第二轴320也是绕转轴200旋转，由于中心齿轮510是固定的，因而小齿轮530既绕中心齿轮510公转，又同时绕第二轴320自转，传动装置500是根据弗格森齿轮传动悖论设计的，小齿轮530绕着中心齿轮510转动一周，转盘齿轮520与中心齿轮510配合小齿轮530的齿数是一样的，由于中心齿轮510比转盘齿轮520多一个齿，则转盘齿轮520转动一个齿对应的角度，也就是转盘齿轮520相对于中心齿轮510缓慢旋转，小齿轮530绕着中心齿轮510转动一周则转盘齿轮520转动一个齿，因而转盘齿轮520与副喷臂400的转速不同，在相对转动的过程中，转盘齿轮520通过触发部521推动副喷臂400绕安装 柱311转动一定角度，副喷臂400的第二喷孔402喷出的水流摇摆，摇摆的水流从不同角度冲刷餐具，能够有效提高对餐具的冲刷效果，有助于提升洗碗机的洗涤效率，实现节水及节能降耗。It can be understood that the main spray arm 300 and the auxiliary spray arm 400 drive the rotating shaft 200 to rotate under the reaction force of the jet water, that is, the second shaft 320 also rotates around the rotating shaft 200. Since the central gear 510 is fixed, the pinion gear 530 It not only revolves around the center gear 510 but also rotates around the second axis 320 at the same time. The transmission device 500 is designed according to Ferguson's gear transmission paradox. The pinion gear 530 rotates around the center gear 510. The turntable gear 520 and the center gear 510 cooperate with the pinion gear. The number of teeth of 530 is the same. Since the center gear 510 has one more tooth than the turntable gear 520, the turntable gear 520 rotates at an angle corresponding to one tooth, that is, the turntable gear 520 rotates slowly relative to the center gear 510, and the pinion gear 530 revolves around the center gear. When 510 rotates once, the turntable gear 520 rotates one tooth, so the rotation speeds of the turntable gear 520 and the auxiliary spray arm 400 are different. During the relative rotation, the turntable gear 520 pushes the auxiliary spray arm 400 to rotate around the mounting column 311 at a certain angle through the trigger part 521 , the water flow ejected from the second nozzle 402 of the sub-spray arm 400 swings, and the swinging water flow washes the tableware from different angles, which can effectively improve the washing effect on the tableware, help improve the washing efficiency of the dishwasher, and achieve water saving and Energy saving.
参照图7，可以理解的是，触发部521采用设置在转盘齿轮520上的第一凸起，第一凸起向副喷臂400延伸，而且具有圆弧形的曲面，副喷臂400设置有第二凸起420，第二凸起420向转盘齿轮520凸起，由于转盘齿轮520与转轴200的转速不同而且方向相反，两者存在相对转动，在相对转动的过程中，利用第一凸起与第二凸起420接触，推动副喷臂400绕安装柱311转动一定角度，实现副喷臂400的第二喷孔402喷出的水流摇摆，提高对餐具的冲刷效果。Referring to Figure 7, it can be understood that the trigger part 521 adopts a first protrusion provided on the turntable gear 520. The first protrusion extends toward the auxiliary spray arm 400 and has an arc-shaped curved surface. The auxiliary spray arm 400 is provided with The second protrusion 420 protrudes toward the turntable gear 520. Since the turntable gear 520 and the rotating shaft 200 rotate at different speeds and in opposite directions, they rotate relative to each other. During the relative rotation, the first protrusion is used. In contact with the second protrusion 420, the auxiliary spray arm 400 is pushed to rotate at a certain angle around the mounting post 311, so that the water flow ejected from the second nozzle 402 of the auxiliary spray arm 400 swings, thereby improving the rinsing effect on the tableware.
参照图7，可以理解的是，第二凸起420偏离副喷臂400的轴线，布置在副喷臂400的侧边。当第二凸起420经过第一凸起所在的位置，由于第二凸起420设在副喷臂400的侧边，则第一凸起通过第二凸起420推动副喷臂400转动一定角度，第二喷孔402喷出的水流实现摇摆，改变冲刷角度，提高对餐具的冲刷效果。Referring to FIG. 7 , it can be understood that the second protrusion 420 is offset from the axis of the auxiliary spray arm 400 and is arranged on the side of the auxiliary spray arm 400 . When the second protrusion 420 passes the position of the first protrusion, since the second protrusion 420 is provided on the side of the auxiliary spray arm 400, the first protrusion pushes the auxiliary spray arm 400 to rotate at a certain angle through the second protrusion 420. , the water flow ejected from the second nozzle hole 402 swings, changes the flushing angle, and improves the flushing effect on the tableware.
参照图11，可以理解的是，转盘齿轮520的上端面设置有五个第一凸起，五个第一凸起周向分布在转盘齿轮520的边缘，五个第一凸起可以是均匀的间隔分布转盘齿轮520与转轴200相对转动一圈，则转盘齿轮520通过五个第一凸起推动副喷臂400改变五次喷水方向，而且由于转盘齿轮520与转轴200的转速不同，改变喷水方向的频率也是变化的，对餐具施加多样性的冲刷，有助于提高冲刷效果，洗涤更干净、快捷。五个第一凸起也可以是不均匀的间隔分布，进一步改变喷水方向的变化频率，冲刷效果更佳。Referring to FIG. 11 , it can be understood that the upper end surface of the turntable gear 520 is provided with five first protrusions, which are circumferentially distributed on the edge of the turntable gear 520 , and the five first protrusions can be evenly spaced. The turntable gear 520 and the rotating shaft 200 rotate one circle relative to each other, and the turntable gear 520 pushes the auxiliary spray arm 400 to change the water spray direction five times through the five first protrusions. Moreover, due to the different rotation speeds of the turntable gear 520 and the rotating shaft 200, the frequency of changing the water spray direction is also changed, and the tableware is subjected to a variety of flushing, which helps to improve the flushing effect, and the washing is cleaner and faster. The five first protrusions can also be unevenly spaced, further changing the frequency of the change of the water spray direction, and the flushing effect is better.
参照图11，可以理解的是，在转盘齿轮520的外周布置一个环形边板522，环形边板522与五个第一凸起为一体成型于转盘齿轮520，环形边板522作为加强筋，提高转盘齿轮520的结构强度。转盘齿轮520的上端面还设置有环形凸筋523，环形凸筋523包围转盘齿轮520中心孔，增加结构强度，减少破裂的风险。Referring to Figure 11, it can be understood that an annular side plate 522 is arranged on the outer periphery of the turntable gear 520. The annular side plate 522 and the five first protrusions are integrally formed on the turntable gear 520. The annular side plate 522 serves as a reinforcing rib to improve the performance of the turntable gear 520. Structural strength of turntable gear 520. The upper end surface of the turntable gear 520 is also provided with an annular convex rib 523. The annular convex rib 523 surrounds the center hole of the turntable gear 520 to increase the structural strength and reduce the risk of rupture.
可以理解的是，触发部521还可以采用设置在上端面的凸边，凸边的上边缘为连续变化的曲面，该曲面的高位点与副喷臂400接触时推动副喷臂400绕安装柱311转动一定角度，该曲面的低位点与副喷臂400预留有间隙，不接触副喷臂400。同样能够实现第二喷孔402喷出的水流摇摆，改变冲刷角度，提高对餐具的冲刷效果。It can be understood that the trigger part 521 can also use a convex edge provided on the upper end surface. The upper edge of the convex edge is a continuously changing curved surface. When the high point of the curved surface contacts the auxiliary spray arm 400, it pushes the auxiliary spray arm 400 around the mounting column. 311 rotates at a certain angle, and a gap is reserved between the low point of the curved surface and the auxiliary spray arm 400, and does not contact the auxiliary spray arm 400. It is also possible to realize that the water flow ejected from the second nozzle hole 402 swings, changes the flushing angle, and improves the flushing effect on the tableware.
参照图2至图5，可以理解的是，中心齿轮510与喷臂座100之间具有连接结构，中心齿轮510设置有多个围绕喷臂座100的支板511，支板511朝向喷臂座100的侧壁设置有第一卡扣512，喷臂座100的外壁设置有第二卡扣102，组装后，支板511的第一卡扣512扣住第二卡扣102，实现中心齿轮510与喷臂座100的连接，同时帮助定位中心齿轮510的轴向位置。Referring to Figures 2 to 5, it can be understood that there is a connection structure between the center gear 510 and the spray arm seat 100, and the center gear 510 is provided with a plurality of support plates 511 surrounding the spray arm seat 100. The support plate 511 is provided with a first buckle 512 on the side wall facing the spray arm seat 100, and the outer wall of the spray arm seat 100 is provided with a second buckle 102.

The transmission device 500 includes a center gear 510, a turntable gear 520 and a pinion gear 530. The center gear 510 and the turntable gear 520 are both set in the middle of the rotating shaft 200. The main spray arm 300 is provided with a gear parallel to the rotating shaft 200. The second shaft 320 is located outside the rotating shaft 200 , and the pinion 530 is sleeved on the second shaft 320 . Among them, the center gear 510 is fixed like the spray arm base 100, the turntable gear 520 can freely rotate relative to the rotating shaft 200, and the pinion gear 530 can freely rotate relative to the second shaft 320. The center gear 510 and the turntable gear 520 both It meshes with the pinion gear 530, and the center gear 510 has one more tooth than the turntable gear 520. It should be understood that, as shown in Figure 6, although the center gear 510 and the turntable gear 520 are different, their tooth pitches are relatively close, and the meshing point between the two and the pinion gear 530 only has 2 to 3 teeth, so the center gear 510 and the turntable gear 520 can mesh with the pinion gear 530 at the same time and realize transmission.
可以理解的是，主喷臂300带动转轴200旋转，即第二轴320也是绕转轴200旋转，由于中心齿轮510是固定的，因而小齿轮530既绕中心齿轮510公转，又同时自转，传动装置500是根据弗格森齿轮传动悖论设计的，小齿轮530绕着中心齿轮510转动一周，转盘齿轮520与中心齿轮510配合小齿轮530的齿数是一样，由于中心齿轮510比转盘齿轮520多一个齿，则转盘齿轮520多转动一个齿对应的角度，也就是转盘齿轮520相对于中心齿轮510缓慢旋转，小齿轮530绕着中心齿轮510转动一周则转盘齿轮520转动一个齿，转盘齿轮520与副喷臂400的转速不同，在相对转动的过程中，转盘齿轮520通过触发部521推动副喷臂400绕安装柱311转动一定角度，副喷臂400的第二喷孔402喷出的水流摇摆，摇摆的水流从不同角度冲刷餐具，有效提高对餐具的冲刷效果，有助于提升洗碗机的洗涤效率，实现节水及节能降耗。It can be understood that the main spray arm 300 drives the rotating shaft 200 to rotate, that is, the second shaft 320 also rotates around the rotating shaft 200.

The transmission device 500 is designed based on Ferguson's gear transmission paradox. The pinion gear 530 rotates around the center gear 510. The turntable gear 520 and the center gear 510 have the same number of teeth of the pinion gear 530. Since the center gear 510 has one more tooth than the turntable gear 520, Then the turntable gear 520 rotates by an angle corresponding to one more tooth, that is, the turntable gear 520 rotates slowly relative to the center gear 510, and the pinion gear 530 rotates around the center gear 510 once, and the turntable gear 520 rotates one tooth, and the turntable gear 520 and the auxiliary spray arm 400 has different rotational speeds. During the relative rotation, the turntable gear 520 pushes the auxiliary spray arm 400 to rotate around the mounting column 311 at a certain angle through the trigger part 521, and the water flow ejected from the second nozzle 402 of the auxiliary spray arm 400 swings.
