Boiler

Abstract

The invention discloses a boiler, comprising a water inlet, a water reservoir and a water outlet, wherein an electromagnetic valve is arranged between the water inlet and the water reservoir; the water reservoir is provided with a control device for controlling the motion of the electromagnetic valve; a buffer room is arranged between the water inlet and the electromagnetic valve; a filter screenis arranged in a conduit between the electromagnetic valve and the water reservoir; the control device comprises a water level switch being connected with and controlling the electromagnetic valve; apushing mechanism is arranged below the water level switch; and the pushing mechanism is contacted with the water level switch for closing the electromagnetic valve. The boiler can reliably keep the water level of the water reservoir to be unchangeable; a floating body floats on the water surface of the water reservoir, and the push rod on the floating body always lies opposite to the water levelswitch; when the push rod floats upwards to contact the water level switch, the electromagnetic valve is closed and water does not enter any more, thus leading the water level of the water reservoir to be maintained at the preset position; synchronously the filter screen can reduce the scale deposit quantity of the water reservoir and the conduit is not heated, thus ensuring the drinking water sanitation maximatily.

Description

technical field [0001] The invention relates to a water boiler. Background technique [0002] Water boilers are widely used in people's daily life, bringing convenience to life. A smart seat is generally provided in the water boiler, and the internal and external air pressures are consistent through the ventilation holes on the smart seat to keep the water level of the water storage tank constant. But in the actual use process, the following problems will occur: the water boiler will accumulate dirt after long-term use, and the dirt may block the air holes on the smart seat and cannot keep the air pressure consistent, causing the water in the water storage tank to overflow. In addition, after the water boiler is used for a long time, scaling will generally occur on the inner wall of the water storage tank, and the water in the water boiler is repeatedly heated in the water storage tank, which will also cause the scale to dissolve in the boiling water due to high temperature...

Problems solved by technology

[0003] The purpose of the present invention is to provide a water boiler, which can effectively solve the problem of overflow of water in the water storage tank caused by dirt blocking the vent hole of the smart seat in the existing water boiler, and the dissolution of scale into the water due to high temperature when the water storage tank is heated. causing unsanitary water problems
