Water heater capable of performing layered water heating

Abstract

The invention discloses a water heater capable of layered heating, which comprises a thermal insulation box body. The inner cavity of the thermal insulation box body is divided into a plurality of auxiliary heating chambers and a main heating chamber through a plurality of partition plates; the leftmost auxiliary heating chamber is connected to the There is a water inlet pipe, and the main heating chamber is connected with a water outlet pipe; there is a long groove in the upper side wall of the insulation box, and a small hole communicating with the long groove is formed on the upper inner wall of each auxiliary heating chamber and the main heating chamber , the long groove is connected with the pressure relief valve; the auxiliary heating chamber is equipped with an automatic sealing switch device, and the sealing plate of the automatic sealing device is pressed against the through hole on the partition plate; the auxiliary heating chamber is provided with a first heating tube , the main heating chamber is provided with a second heating tube and a temperature detector. A plurality of auxiliary heating chambers and a main heating chamber of the present invention can be heated independently; meanwhile, it is provided with a pressure relief valve, which can effectively control the maximum air pressure of the auxiliary heating chamber and the main heating chamber; hot.

Description

Technical field: [0001] The invention relates to the technical field of water heaters, in particular to a water heater capable of layered heating. Background technique: [0002] When the existing water heater is heated by electricity, the water in the entire heat preservation water tank is heated, and the cold water and the superheated hot water are mixed in a space volume. Because of the large amount of water storage, it takes a long time to heat the water in the entire water tank, and the water temperature is also difficult. Rapid improvement, high power consumption and energy consumption. Moreover, the heating tube in the existing water heater is a heating tube, so its maximum heating rate is limited, and the water cannot be heated quickly, so that the heating rate drops, and its heating efficiency is inconvenient, and cannot be more needed. To change, the user can only adjust the amount of cold water and hot water. Invention content: [0003] The purpose of the prese...
