Drain valve assembly and washing machine

Abstract

The invention discloses a drain valve assembly and a washing machine. The drain valve assembly comprises a valve body, wherein a first water hole and a second water hole are formed in the valve body, a drain cavity guiding water from the first water hole to the second water hole is formed in the valve body, a valve unit used for connecting / disconnecting a water path between the first water hole and the second water hole is arranged in the drain cavity, the drain cavity comprises a heating cavity and a valve cavity, the heating cavity is in communication with the first water hole, the valve cavity is in communication with the second water hole, the valve unit is arranged in the valve cavity, and a heating unit is arranged in the heating cavity. The washing machine comprises a barrel assembly and a circulating device, wherein the circulating device is provided with a water inlet end and a water outlet end, the barrel assembly is provided with a water outlet, the first water hole is in communication with the water outlet, the water inlet end of the circulating device is in communication with the heating cavity, and the water outlet end is used for circularly supplying water into the barrel assembly. The heating unit is arranged in the valve body cavity of the drain valve and integrated with the drain valve into an independent module structure, so that the drain valve assembly is simple in structure, and convenient to machine and produce.

Description

technical field [0001] The invention belongs to the field of washing equipment, and in particular relates to a drain valve assembly and a washing machine with the drain valve assembly. Background technique [0002] Most of the laundry detergents sold on the market wash dirt through active enzymes, and the activity of active enzymes is the strongest at around 40 degrees. When winter comes and the temperature drops, especially in the north, the solubility of washing powder in water will obviously decrease, resulting in a large amount of washing powder remaining on the clothes after a washing cycle in the washing machine, not only the clothes are not washed clean, but also wasted water and time. [0003] Some manufacturers have developed washing machines with water heating function. Most of them install heating pipes at the bottom of the washing machine’s water tank to realize heated water washing. One end of the heating pipe protrudes from the outside of the bottom of the bu...

Problems solved by technology

[0005] There are also some manufacturers who install a heating module at the bottom of the washing machine tub, for example, a heating module with a separate heating space set on the circulating water pipe, or replace the circulating pump with a heating pump, but this improved structure also has installation difficulties and increased costs The most serious defect is that the added heating module is heavier, and it is installed at the bottom of the water tank, causing the center of gravity of the water tank to shift, affecting the balance of the water tank, and causing serious consequences
