Background technique

The automatic washing machine generally consists of a washing machine box, a control disc holder, an outer tub, an inner tub, a pulsator and a transmission system. The control disc seat is installed on the upper part of the washing machine box, and is generally made of high-strength plastic, such as PP, ABS, etc. There is a control panel or a rear control panel in front of the control panel. The control panel is mainly used to fix and install control components, that is, electrical components, such as computer boards, water level switches, power switches, micro switches, reed switches, safety switches, stop switches, water inlet switches, water inlet valves, etc. It is equipped with a water injection port, a disinfection box and a driver for injecting water into the bucket. The top of the control disc seat is provided with an upper cover. Due to poor sealing or long-term use, water is easily introduced in the part, and a drain is usually provided on the control disc seat. The water through hole drains the water.

Patent CN200420097604.4 provides a washing machine control disc holder, which comprises a control disc housing body, wherein the housing body has a water leakage hole, wherein the bottom surface of the housing body is provided with at least one water guiding groove lower than the bottom surface of the housing body, and the water leakage hole is provided. On the surface of the diversion ditch. The water droplets leaking into the control tray seat will be led to the water leakage hole along the inclined surface of the water guiding groove and leak back to the washing tub, thereby solving the problem that the water in the control socket is not completely discharged, but the water leakage hole is a through hole in the washing machine detection. The test finger is used for the detection of the part. After the test enters the control tray from the leak hole, if it touches the electrical component, it is unqualified. Therefore, since the drain hole is a through hole, the through hole can only be set smaller. The water discharge speed is small, and it is easy to affect the electrical components.

The blocking plate 2-1 is a straight plate, and one end of the blocking plate 2-1 is fixedly connected with a lower portion of the bottom wall 1 of the closed chamber, usually welded, and the other end of the blocking plate 2-1 extends below the opening 1-1, and the blocking plate 2-1 has a certain angle θ with the axial direction of the opening 1-1, and the gap between the blocking plate 2-1 and the bottom wall 1 of the closed chamber Forming the water outlet 1-2, the projection of the blocking plate 2-1 in the horizontal direction covers the projection of the opening 1-1, so that the opening 1-1 is completely within the range of the blocking plate 2-1, and the blocking plate 2-1 will enter the opening 1 The direction of the water of -1 is changed from the vertical direction to the direction of the blocking plate 2-1, and the area of the water outlet 1-2 is increased with respect to the area of the opening 1-1, which can increase the amount of water discharge and the speed of water discharge, and also because of the blocking plate 2 -1 has a certain angle θ with the axial direction of the opening 1-1, the test finger cannot enter from below the opening 1-1, and can only be inserted obliquely into the opening 1-1 along the blocking plate 2-1, which increases the water outlet 1-2 simultaneous limit test refers to entry.

As shown in FIG. 3, the blocking plate 2-1 may also include a vertical plate and a horizontal plate. One end of the vertical plate is welded or integrally formed with the horizontal plate, and the other end of the vertical plate is welded to the bottom outer wall of the closed chamber. The other end of the horizontal plate extends below the opening 1-1, and the projection of the opening 1-1 in the horizontal direction is completely within the projection range of the horizontal plate, and the horizontal plate end forms a water outlet 1-2 with the bottom wall 1 of the closed chamber.

The blocking plate 2-1 may also be composed of two connecting plates. The two connecting plates are welded or integrally formed. The connecting plates have an angle after joining, and the angle may be a right angle or an acute angle or an obtuse angle. Preferably, the right angle or the obtuse angle is used, so that the blocking plate 2-1 can block the entry of the test finger without affecting the water discharge, and facilitate the discharge of water.

When the length of the water outlet 1-2 in the vertical direction satisfies the insertion of the test finger from the water outlet 1-2 to the opening 1-1, the test finger cannot touch the electrical component.

Alternatively, the drain structure 2 is an elbow, one end of which is in communication with the opening 1-1, and the other end is a water outlet 1-2, and the curved section of the elbow forms a curved portion of the drain passage. When the test refers to entering from the water outlet 1-2, the test finger is stopped in the curved section of the curved pipe. The curved segments can also be set to multiple.

Embodiment 3

As shown in FIG. 4, this embodiment is further defined in the first embodiment. The edge of the opening 1-1 extends downward to form a tubular structure 3. The lower end of the tubular structure 3 is contracted to form a blocking end to block the flow of water. Next, the water outlet 1-2 is provided on the pipe wall to direct the water flow to the side to form a curved portion of the drain flow passage.

Further, the central axis of the water outlet 1-2 has an angle with the central axis of the tubular structure 3, and the angle may be a right angle, an acute angle or an obtuse angle, preferably a right angle or an acute angle.

More recently, the central axis of the water outlet 1-2 is perpendicular to the central axis of the opening 1-1. Since the opening 1-1 is disposed on the bottom wall of the closed chamber, the water flows vertically through the opening position, the water outlet 1-2 is horizontal, and the water flow has a curved portion in the tubular structure, and the test finger is out. After the nozzle 1-2 enters, it is resisted by the side wall of the tubular structure 3, and cannot enter the closed chamber 3 upwards, so that the electrical component is not touched, so the structure can make the water outlet 1-2 large and convenient. Drain the water.

Further, the water outlet 1-2 is opened near the blocking end, so that even if the test finger is a bending test finger, it is difficult to touch the electrical component due to the limitation of the length of the curved end.

Further, the lower edge of the water outlet 1-2 is flush with the blocking end, and the water does not have a blocking portion at the water outlet 1-2 to facilitate water discharge.

Embodiment 4

As shown in FIG. 5, this embodiment is further defined by the first embodiment.

When the test finger is used for the test, the test finger is stopped by the bent portion after entering the water outlet 1-2, and the electrical component cannot be moved upward to touch the electrical component to meet the electrical safety inspection requirements, and the diameter of the water outlet 1-2 can be set. Larger, as long as the test finger can not reach the electrical component when extending from the water outlet 1-2 to the opening 1-1, the opening of the water outlet 1-2 can increase the water discharge and the water discharge speed. The structure makes the drainage structure simple and easy to manufacture

Further, the lower end edge of the water outlet 1-2 is flush with the upper surface of the blocking plate 4 to improve the fluency of the water flow, and the water outlet is located near the lower portion of the tubular structure, so that the water outlet 1-2 and the opening 1 -1 The distance between the vertical direction is large, which satisfies the detection requirements of the straight rod type test rod, and also satisfies the detection requirements of the bending test finger in accordance with the electrical safety test, and the structure is safer.
