Problems solved by technology

[0002] At present, the existing technical solutions for draining or cleaning water heaters are mainly divided into two categories: one is that there is no drain valve, which requires professionals to use special tools to realize the draining and cleaning of the inner tank of the water heater, which is not convenient for users to do it themselves. Cleaning and maintenance; the other type has a blowdown valve, only need to open the switch of the blowdown valve to realize the blowdown of the inner tank of the water heater, but the blowdown effect of this scheme is not good, and the efficiency is relatively low, which brings It is very inconvenient and cannot meet the needs of users

Abstract

The invention discloses a water heater and a blowdown apparatus and a blowdown control method thereof. The blowdown apparatus for the water heater comprises a blowdown pipe, a blowdown valve, a gas inlet pipe, a gas inlet valve, a water inlet valve and a controller, wherein the blowdown pipe is connected with a liner of the water heater; the blowdown valve is connected with the blowdown pipe and is used for controlling the blowdown pipe; the gas inlet pipe is connected with the liner; the gas inlet valve is connected with the gas inlet pipe and is used for controlling the gas inlet pipe; the water inlet valve is connected with a water inlet pipe of the water heater and is used for controlling the water inlet pipe; the controller is respectively connected with the blwowdown valve, the gas inlet valve and the water inlet valve; after the controller receives a blowdown command, the controller controls the blowdown valve to be opened, controls the water inlet valve to be closed and simultaneously controls the gas inlet valve to be opened so as to enable the air to enter the liner. According to the invention, rapid and efficient drainage of sewage from the liner can be implemented; the liner can be flushed; more clean and sanitary bathing water is provided for people; meanwhile, the blowdown apparatus can realize that a user is regularly reminded to carry out blowdown and real-time display of the emptying progress, emptying reminding and the like, and better meets the requirements of people.
