Water purifier and control method thereof

Abstract

The invention discloses a water purifier and a control method thereof. The water purifier is characterized in that a raw water inlet of a filtering system is connected with a raw water pipeline; a purified water outlet of the filtering system is connected with a water inlet end of the flow control pump; the flow control pump is connected with the water inlet end of the instant heating body through a normal-temperature pipeline and an auxiliary heating pipeline. A second electromagnetic valve, a one-way check valve and a phase change auxiliary heating body comprising a phase change material are arranged in the auxiliary heating pipeline; the phase change of the phase change material can absorb or release heat so as to adjust the water temperature in the auxiliary heating pipeline; a flow meter is further arranged between the flow control pump and the water inlet end of the instant heating body; the controller is electrically connected with the instant heating body and the phase change auxiliary heating body, and the phase change material auxiliary heating body is arranged on a waterway at the front end of the instant heating body, so that the heating speed of the instant heating body can be increased, and the water outlet flow speed of hot water at the water outlet end of the instant heating body can be increased.

Description

technical field [0001] The present disclosure relates to the technical field of water purification control, in particular to a water purifier and a control method thereof. Background technique [0002] At present, domestic water purifier products, in order to facilitate the living habits of users, more and more use thick-film heating tubes to heat drinking water, so that they can be taken as they are used, burned as much as they are used, and avoid waiting for boiling water and storing heat. Water is troublesome; however, due to the safety regulations of domestic household appliances, the maximum power of conventional household heating appliances can only reach 2200W. Above 95°C (defined as boiling water), the maximum output of boiling water per minute = 2200*60 / (4200*(95-25)) = 449g, that is, the flow rate of water is less than 450mL / min, and the user needs to wait for a cup of 300mL water More than 40 seconds, the experience is not good.
