Example 1

The present embodiment provides a water inlet valve assembly, as shown in fig. 4, 5 and 6, including: an inlet pipe 1 including a water inlet 22 and a water outlet 32; the filter screen 4 is movably connected in the water inlet pipeline 1, filter holes are formed in the filter screen 4, and the filter screen 4 is provided with a first position and a second position, wherein the first position is perpendicular to the water inlet direction of the area where the filter screen 4 is located and used for plugging the water inlet pipeline 1, and the second position is used for opening the water inlet pipeline 1; a drive mechanism for controlling the movement of the sieve 4 between the first position and the second position. In the water inlet valve component of the scheme, the filter screen 4 is in the first position in the use process. The water flowing in from the external water supply network enters the water inlet pipeline 1 and then enters the dish-washing machine after being filtered by the filter screen 4. The impurities such as water rust, silt and the like in the water can be blocked by the filter screen 4. After the valve subassembly that intakes used a period, the user can control filter screen 4 through actuating mechanism and take place the action, makes filter screen 4 open by the shutoff state, opens the back and starts the procedure of drawing water again, washes away the impurity on the filter screen 4 and discharges in the suction dish washer when the rivers enter into.

The structure of the strainer 4 is not particularly limited, and as shown in fig. 5 and 6, in the present embodiment, the strainer 4 has a filtering surface, and the filtering surface is disposed toward the water inlet direction in the first position. The filtering surface is used for blocking impurities in the filtered water flow when the water inlet valve assembly is in normal use. Most of the impurities will adhere to the filter surface. Therefore, when the filter screen 4 is opened, the filter surface can be washed by water flow to wash away impurities. In this embodiment, there is only one filtering surface of the filter screen 4. The filter screen 4 is in the filtering state only when the filtering surface is opposite to the water flow entering direction. When the filtering surface faces away from the filter screen 4, water flow impacts on the filter screen 4, and filtering holes in the filter screen 4 are impacted in the reverse direction, so that the filtering holes blocked by impurities can be flushed. As an alternative embodiment, both faces of the screen 4 are filtering faces.

In this embodiment, as shown in fig. 4, the driving mechanism is disposed outside the water inlet pipe 1. The installation and the control of the driving mechanism are convenient.

Wherein, as shown in fig. 5, fig. 6, filter screen 4 rotates to be connected on the lateral wall of inlet channel 1, through rotating the mode of connecting, can make filter screen 4 present more different angles when being in the second position, because the flow direction of rivers can be regarded as unchangeable, consequently when filter screen 4 rotates and presents different angles, rivers have different impact angle when 4 surperficial emergence impacts of filter screen, consequently can be more abundant with filter screen 4 surface wash clean. The actuating mechanism of this embodiment is step motor 5, and filter screen 4 is connected to step motor 5's output, and filter screen 4 rotates to be connected on the inner wall of inlet channel 1. The stepping motor 5 can output torque more precisely, thereby controlling the rotation angle of the screen 4 more precisely. As an alternative, the driving mechanism in this embodiment may be a link mechanism, one end of the link mechanism controls the movement of the filter screen 4, and the other end of the link mechanism extends out, so as to facilitate manual control by a user.

In this embodiment, as shown in fig. 6, a gap is left between the filter screen 4 and the inner wall of the water inlet pipe 1. Need move for the inner wall of inlet channel 1 when filter screen 4 takes place the action, consequently leave the clearance between filter screen 4 and the inner wall of inlet channel 1 in this scheme, the frictional resistance that needs overcome when can reducing filter screen 4 and rotate. Wherein, the clearance between filter screen 4 and the 1 inner wall of inlet channel is no longer than 0.5mm, prevents that impurity from getting into inside the dish washer through the clearance, influences the washing of the inside tableware of dish washer. When the gap is larger than 0.5mm, the flow of water through the gap increases, and thus more impurities can pass through the gap. Meanwhile, impurities larger than 0.5mm when the gap is increased also have a possibility of entering the inside of the dishwasher through the gap. When the tableware is washed in the dish washer, the relatively large impurities are easy to scratch the surface of the tableware when impacting the tableware along with water flow. When the clearance is too narrow, because the motor is connected to the filter screen, the vibrations that take place in the motor working process influence the filter screen easily and take place vibrations to lead to filter screen and inlet channel 1 inner wall to take place the striking damage. On the other hand, a relatively small gap increases the frictional resistance experienced by the screen during rotation. Therefore, the gap can also realize the protection of the tableware cleaned in the dishwasher on the basis that the filter screen can smoothly rotate, and the filtering performance of the filter screen is kept.

The structure of the intake valve assembly in this embodiment is not particularly limited, and in this embodiment, as shown in fig. 4 to 6, the intake valve assembly further includes: the water inlet valve comprises a first valve body 2 and a second valve body 3, wherein the first valve body 2 and the second valve body 3 are integrally connected, and a water inlet pipeline sequentially penetrates through the first valve body 2 and the second valve body 3 along the direction from a water inlet 22 to a water outlet 32. The first valve body 2 and the second valve body 3 are used for connecting a water supply network and a water pipe structure inside the dishwasher, respectively. As an alternative embodiment, the inlet valve assembly may further comprise a third valve body connected to the outlet end of the second valve body 3 in turn. As another alternative embodiment, the intake valve assembly comprises only the first valve body 2.

The angle between the first valve body 2 and the second valve body 3 is not particularly limited, and in the present embodiment, as shown in fig. 4, the first valve body 2 and the second valve body 3 are perpendicular to each other. The first valve body 2 and the second valve body 3 which are perpendicular to each other can meet the installation requirements of different angles between the water inlet network pipeline and the internal pipeline of the dish-washing machine. As an alternative embodiment, the first valve body 2 and the second valve body 3 are arranged at an acute angle or an obtuse angle to meet the installation requirements of different installation angles.
