Embodiment

[0039] In the present invention, a spring-back assembly is provided between the liquid outlet pipe of the liquid storage box and the liquid suction pipe of the liquid suction pump. The sealing tapered surface of the liquid box is in close contact, and the liquid outlet pipe of the liquid storage box is closed to avoid liquid leakage; the end of the rebound plug is provided with a confluence cavity, when the suction pipe of the liquid pump is connected to the liquid outlet pipe of the liquid storage box At this time, under the action of the liquid pump, the detergent in the liquid storage box first enters the confluence cavity, and then enters the liquid pump to avoid discontinuous liquid pumping; the rebound plug shortens the distance between the sealing ring and the sealing surface, making the The rebound time of the spring is reduced, reducing the amount of fluid leakage when the reservoir pops out.

Abstract

The invention provides a rebound plug assembly of an automatic feeding device and a washing machine having the same, wherein the automatic feeding device has a liquid suction pump and a liquid storage box; Between the suction pipes of the pump; the rebound plug assembly includes a rebound plug, a spring and a seal ring; the rebound plug has a seal ring groove and a spring guide rail, the spring is set on the spring guide rail, and the seal ring is set in the seal ring groove middle; under the action of external force and spring, the springback plug drives the sealing ring to move to realize the opening or closing of the liquid outlet pipe of the liquid storage box; the end of the springback plug has a confluence chamber, including a confluence chamber inlet and a confluence chamber outlet, The inlet of the confluence cavity communicates with the liquid storage box, and the outlet of the confluence cavity communicates with the liquid suction pump. The rebound plug provided by the present invention shortens the spring rebound time and reduces the liquid leakage of the liquid storage box; when the liquid pump pumps liquid, the structure of the confluence cavity avoids the occurrence of discontinuous liquid pumping.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a rebound plug assembly of an automatic feeding device and a washing machine having the same. Background technique [0002] With the development of science and technology, washing machine intelligent delivery technology is more and more applied to the working process of washing machine. The intelligent dosing technology can accurately add the amount of detergent according to the amount of laundry, avoiding the inaccurate dosage of detergent caused by artificial dosing of detergent; in addition, the smart dosing technology can put in a large amount of detergent at one time, which can be used for a long time and is extremely It greatly saves the time and cost of adding detergent for each laundry. [0003] The existing multi-barrel laundry processing device seals the detergent box through the rebound plug assembly to avoid the leakage of detergent; but when the detergent ...
