Instant liquid heater

Abstract

The invention relates to the field of articles for daily use, in particular to an instant liquid heater which comprises a heating device 3 with the two ends separately provided with a temperature adjustment pipe water inlet 321 and a water outlet 312, a temperature adjustment device 4, and a water pump 5 connected with the temperature adjustment pipe water inlet 321. The instant liquid heater is characterized in that the heating device 3 is a temperature-adjustable water circulation system, the lower portion of a temperature adjustment pipe 32 is the temperature adjustment pipe water inlet 321, a water overflow outlet 322 is formed in the upper portion of the temperature adjustment pipe 32, the temperature adjustment pipe 32 and a circulation pipe 33 are connected through the water overflow outlet 322, a heating pipe 31 and the temperature adjustment pipe 32 are connected through a heating pipe water inlet 311 in the lower portion of the temperature adjustment pipe 32, and a backflow inlet 331 in the lower portion the circulation pipe 33 is connected with the temperature adjustment pipe water inlet 321. According to the instant liquid heater, the temperature is controlled through a pure physical and mechanical structure, the production cost is lowered, and the service life of equipment is prolonged; and the temperature-adjustable water circulation system prevents counter-flushing of hot water and cold water from affecting the water quality and the equipment, can achieve temperature control without delay, and is large in temperature adjustment interval.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to an instant liquid heater. Background technique [0002] With the development of social urbanization, technology, and humanization, instant electric water heaters are increasingly used in the daily lives of ordinary people, such as instant water dispensers, instant faucets, and instant water heaters. These instantaneous heating devices bring great convenience to people, save energy, save time, and are convenient, time-saving and energy-saving. [0003] However, the current temperature control method of the instant water heater mostly adopts a circuit board temperature control design. During the heating process, the circuit board is easy to be burned due to excessive temperature. [0004] The purpose of the present invention is to provide a new instant heating body with adjustable temperature, which changes the temperature control principle of the heating body.
