Energy-saving water heater with adjustable heating rate

Abstract

The invention discloses an energy-saving water heater with adjustable heating rate. The energy-saving water heater comprises an inner container of the water heater, wherein a water inlet pipe is fixedly connected with the upper end of the inner container; a water outlet pipe is fixedly connected with the lower end of the inner container; a first temperature sensor and a second temperature sensor are fixedly connected with the inner side walls, close to the water inlet pipe or the water outlet pipe, of the inner container respectively; a liquid level sensor is fixed in the inner container; a plurality of heating assemblies are fixed at the lower end of the inner container; each heating assembly comprises a ceramic outer sleeve inserted in the inner container, an L-shaped retainer ring is formed at the lower end of the ceramic outer sleeve, a vertical thread sleeve is formed on the outer side edge of the retainer ring, the thread sleeve penetrates through the side wall of the inner container and is in threaded connection with a copper thread sleeve which is propped against the outer wall of the inner container, an annular channel is formed in the copper thread sleeve, a baffle ring is formed on the outer wall of the thread sleeve, and a seal ring is fixedly adhered to the lower end surface of the baffle ring and pressed on the inner wall of the inner container. According to the energy-saving water heater with the adjustable heating rate, electrochemical corrosion can be avoided, and meanwhile, heating time of the water heater can be adjusted.

Description

Technical field: [0001] The invention relates to the technical field of water heaters, in particular to an energy-saving water heater with adjustable heating speed. Background technique: [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. Existing water heaters are generally equipped with an inner tank, and a heating device is provided in the inner tank, and the heating device generally adopts an electric heating method, and generally only one heating device is provided, and the heating speed cannot be adjusted, and the electric heating device is used instead. The weak link of the water heater is the safety of electric heating and the time of electric heating; at the same time, the electric heating device generally uses metal tubes for heating, and its metal material is the same as that of the inner tank of the water heater, which is prone to electrochemical c...
