Vertical heat preservation water tank

Abstract

The invention discloses a vertical heat preservation water tank. The vertical heat preservation water tank comprises a box body, three partitioning devices, a plurality of electric heating devices, two temperature sensors and a liquid level sensor. The box body is partitioned into a first cavity, a second cavity, a third cavity and a fourth cavity from bottom to top in sequence through the three partitioning devices respectively. The second cavity can be communicated with the first cavity or the third cavity in use according to setting of a user. The electric heating devices are arranged at the lower end in the third cavity and the lower end in the fourth cavity respectively. The number of the electric heating devices in the third cavity is larger than that of the electric heating devices in the fourth cavity. The two temperature sensors are arranged in the third cavity and the fourth cavity respectively and located above the electric heating devices. The liquid level sensor is arranged at the lower end in the fourth cavity. The vertical heat preservation water tank has the beneficial effects of being low in energy consumption, high in energy efficiency, stable in outlet water temperature, capable of providing hot water continuously, convenient to use, high in comfort and the like.

Description

technical field [0001] The invention relates to the technical field of water heaters. More specifically, the present invention relates to a vertical heat preservation water tank. Background technique [0002] At present, there are two main forms of thermal insulation water tanks for solar energy: single-compartment thermal insulation water tanks and double-compartment thermal insulation water tanks. Among them, the single-compartment insulated water tank will replenish cold water while releasing hot water. After the cold water is added, it will mix with hot water to reduce the temperature of the hot water, resulting in the temperature of the heated hot water not meeting the standard, the water temperature is unstable, and the supply of hot water Small size and low energy efficiency; although the double-chamber insulated water tank solves the problem of small hot water supply to a certain extent, there is still the problem of unstable water temperature when a large amount of...

Among them, the single-compartment insulated water tank will replenish cold water while releasing hot water. After the cold water is added, it will mix with hot water to reduce the temperature of the hot water, resulting in the temperature of the heated hot water not meeting the standard, the water temperature is unstable, and the supply of hot water Small size and low energy efficiency; although the double-chamber insulated water tank solves the problem of small hot water supply to a certain extent, there is still the problem of unstable water temperature when a large amount of hot water is used in a short period of time, and it is different from the high-temperature chamber in the double chamber. Due to the high temperature of the connected heat collecting tube, the heat transfer efficiency of the heat collecting tube is reduced and the energy efficiency is low
