It is to be understood that the specific embodiments described herein are merely illustrative and not restrictive. In addition, it should be noted that, for the convenience of description, only some but not all of the related parts are shown in the drawings.
实施例一 Embodiment 1
如图1-3所示，本实施例提供了一种进水水流控制装置，降低了进水水流下落的高度，解决了水流飞溅和水流外溢的问题，同时还降低了水流冲击的噪音。所述进水水流控制装置包括导流腔体1，所述导流腔体1上开有相对设置的进水口11和出水口12，且所述出水口12的口径大于所述进水口11的口径，所述出水口12处设有多个使进水水流分流的导流板2。As shown in FIG. 1-3, the embodiment provides an inflow water flow control device, which reduces the height of the inflow water flow, solves the problem of water flow splash and water overflow, and reduces the noise of the water flow impact. The inlet water flow control device includes a flow guiding cavity 1 having a water inlet 11 and a water outlet 12 disposed opposite to each other, and the water outlet 12 has a larger diameter than the water inlet 11 In the caliber, the water outlet 12 is provided with a plurality of baffles 2 for diverting the influent water flow.
在本实施例中，所述导流腔体1包括纵向截面为梯形的导流槽。如图1所示，导流槽为四棱台形状，也可以为圆锥台形状。导流槽的槽底开设进水口11，且进水口11靠近导流槽的一侧的槽壁，导流槽的槽口即为出水口12，出水口12的口径大于进水口11的口径，在导流槽的进水口11处连接导流管3，导流管3将导流槽与贮水槽进水孔5连通。导流管3与导流槽形成台阶状，进水水流通过导流管3进入到导流槽内，对下落的水流起到了缓冲的作用，降低了水流下落的距离，避免了水流直接冲击洗衣机贮水槽6的槽壁而产生溅射的问题。In the present embodiment, the flow guiding cavity 1 includes a flow guiding groove having a trapezoidal longitudinal section. As shown in Fig. 1, the flow guiding groove has a quadrangular prism shape, and may have a truncated cone shape. The water inlet 11 is defined in the bottom of the groove of the guide groove, and the water inlet 11 is close to the groove wall on the side of the flow channel. The groove of the flow channel is the water outlet 12, and the diameter of the water outlet 12 is larger than the diameter of the water inlet 11. The draft tube 3 is connected to the water inlet 11 of the diversion tank, and the draft tube 3 communicates the diversion tank with the water inlet hole 5 of the water storage tank. The guiding tube 3 and the guiding groove form a step shape, and the influent water flows into the guiding trough through the guiding tube 3, thereby buffering the falling water flow, reducing the distance of the water flow falling, and avoiding the direct impact of the water flow on the washing machine. The groove wall of the water storage tank 6 causes a problem of sputtering.
为了防止导流槽内的水压过大，在导流槽的一侧槽壁上开设有泄流孔13，泄流孔13由导流槽的槽底向槽口延伸，进入到导流槽内的一部分水会通过泄流孔13流入洗衣机贮水槽6内。上述的泄流孔13还起到了通气的作用，避免了在进水水流比较大时出现呛水等问题。In order to prevent the water pressure in the flow guiding groove from being excessively large, a drain hole 13 is opened in the groove wall of one side of the guiding groove, and the drain hole 13 extends from the bottom of the guiding groove to the notch and enters the guiding groove. A part of the water inside flows into the washing machine water tank 6 through the drain hole 13. The above-mentioned drain hole 13 also functions as aeration to avoid problems such as water leakage when the influent water flow is relatively large.
如图2和图3所示，出水口12倾斜设置(也即，所述出水口12的端面为倾斜面)，出水口12倾斜的角度与洗衣机贮水槽6侧壁的倾斜角度一致，将导流槽安装到洗衣机上时，出水口12与洗衣机贮水槽6的侧壁有一定的缝隙供水流流出。As shown in FIG. 2 and FIG. 3, the water outlet 12 is inclined (that is, the end surface of the water outlet 12 is an inclined surface), and the angle at which the water outlet 12 is inclined is the same as the inclination angle of the side wall of the washing machine water tank 6, and will be guided. When the launder is mounted on the washing machine, the water outlet 12 and the side wall of the washing machine water tank 6 have a certain gap and the water supply flows out.
在出水口12周边的边缘连接有连接板4，且连接板4倾斜的角度与出水口12倾斜的角度一致，导流板2安装在连接板4上。在本实施例中，靠近出水口12的导流槽的槽壁的边缘没有设置连接板4，其余的三个槽壁的边缘均连接有连接板4。A connecting plate 4 is connected to the periphery of the water outlet 12, and the angle at which the connecting plate 4 is inclined coincides with the angle at which the water outlet 12 is inclined, and the deflector 2 is mounted on the connecting plate 4. In the present embodiment, the connecting plate 4 is not provided at the edge of the groove wall of the flow guiding groove near the water outlet 12, and the connecting plates 4 are connected to the edges of the remaining three groove walls.
具体地，导流板2包括第一导流板21和第二导流板22，第一导流板21和第二导流板22分别安装在连接板4上，且置于出水口12相对的两侧，第一导流板21和第二导流板22均为弧形板，第一导流板21朝向第二导流板22弯曲，第二导流板22朝向第一导流板21弯曲，第一导流板21和第二导流板22弯曲的最低点分别与与其相对应的导流槽的槽壁置于同一平面上。弯曲的导流板2使水流形成扇形，按照预定的方向流入洗衣机贮水槽6内。Specifically, the baffle 2 includes a first baffle 21 and a second baffle 22, and the first baffle 21 and the second baffle 22 are respectively mounted on the connecting plate 4, and are placed opposite to the water outlet 12. On both sides, the first baffle 21 and the second baffle 22 are both arcuate plates, the first baffle 21 is bent toward the second baffle 22, and the second baffle 22 faces the first baffle 21 is bent, and the lowest points at which the first baffle 21 and the second baffle 22 are bent are respectively placed on the same plane as the groove walls of the corresponding guide grooves. The curved baffle 2 causes the water flow to form a fan shape and flows into the washing machine water tank 6 in a predetermined direction.
在第一导流板21和第二导流板22之间还设有至少一个第三导流板23，第三导流板23为弧形板，第三导流板23朝向第一导流板21或第二导流板22弯曲。第三导流板23的设置将水流分成多路水流，且使多个水流按照预定的方向汇入一点，同时使多个水流能够沿着洗衣机贮水槽6的槽壁进行汇流，降低了水流的冲击噪音，避免了水流外溢的问题。在本实施例中，第三导流板23设置一个，且第三导流板23朝向第二导流板22弯曲。第三导流板23设置的数量和高度均可以根据实际需求进行设置，在此不再叙述。At least one third baffle 23 is further disposed between the first baffle 21 and the second baffle 22, the third baffle 23 is a curved plate, and the third baffle 23 faces the first diversion The plate 21 or the second deflector 22 is curved. The arrangement of the third baffle 23 divides the water flow into a plurality of water flows, and causes the plurality of water flows to merge into a point in a predetermined direction, while allowing the plurality of water streams to flow along the groove wall of the washing machine water storage tank 6, reducing the water flow. Impact noise avoids the problem of water overflow. In the present embodiment, one third baffle 23 is provided, and the third baffle 23 is bent toward the second baffle 22. The number and height of the third deflector 23 can be set according to actual needs, and will not be described here.
本实施例还提供了一种洗衣机，包括上述的进水水流控制装置，有效地降低了洗衣机工作时的噪音，解决了水流溅射和外溢的问题，提高了用户的满意度。The embodiment further provides a washing machine, comprising the above-mentioned inlet water flow control device, which effectively reduces the noise of the washing machine during operation, solves the problem of water flow sputtering and overflow, and improves user satisfaction.
