Drainage assembly and electric water heater

Abstract

The invention discloses a drainage assembly and an electric water heater. The drainage assembly comprises a rotary connector and a drainage pipe, wherein the rotary connector is provided with a waterinlet end and a water outlet end; one end of the drainage pipe is connected with the inner wall face of the rotary connector, the other end of the rotary connector stretches out of the water inlet endof the rotary connector, and the water wall face of the drainage pipe is spaced from the inner wall face of the rotary connector; and the water inlet end of the rotary connector is arranged on a water outlet pipe located in an inner container the electric water heater in a sleeving mode and is connected with the water outlet pipe in a screwed mode, and the drainage pipe penetrates through the water outlet pipe to extend into the inner container of the electric water heater. Screwed connection has the advantage of convenient assembling and disassembling so that the drainage assembly and the water outlet pipe of the inner container can be conveniently disassembled and assembled; when incrustation in the inner container needs to be removed, the drainage assembly is disassembled first, then the incrustation in the inner container is impacted by water to be discharged out of the water outlet pipe of the inner container, afterwards, the drainage assembly is connected to the water outlet pipe of the inner container in the screwed mode again, and thus, the incrustation in the inner container can be removed conveniently.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a drainage assembly and an electric water heater. Background technique [0002] The electric water heater mainly includes: inner tank, heating device, control device, water inlet pipe, drain pipe, magnesium rod and other components; among them, the water inlet pipe and drain pipe are fixedly connected with the inner tank, that is, the water inlet pipe and the drain pipe are respectively connected with the inner tank. When assembling, the water inlet pipe and the water inlet of the inner tank are connected and fixed, and the drain pipe and the outlet of the inner tank are fixed by interference fit, that is, when the water inlet pipe and the drain pipe are disassembled, the water inlet pipe and the drain pipe will be damaged And can't continue to use, so just make the water inlet pipe of electric water heater and drainpipe dismantling inconvenience. [0003] However...

[0002] The electric water heater mainly includes: inner tank, heating device, control device, water inlet pipe, drain pipe, magnesium rod and other components; among them, the water inlet pipe and drain pipe are fixedly connected with the inner tank, that is, the water inlet pipe and the drain pipe are respectively connected with the inner tank. When assembling, the water inlet pipe and the water inlet of the inner tank are connected and fixed, and the drain pipe and the outlet of the inner tank are fixed by interference fit, that is, when the water inlet pipe and the drain pipe are disassembled, the water inlet pipe and the drain pipe will be damaged And can not continue to use, so that the water inlet pipe and drain pipe of the electric water heater are disassembled inconveniently.

[0003] However, if the electric water heater is used for a long time, scale will adhere to the inner wall of the inner tank. Because the water inlet pipe and drain pipe of the electric water heater are inconvenient to disassemble, it will be inconvenient to discharge the scale in the inner tank of the electric water heater, and then the sewage of the electric water heater will be discharged.
