Vertical water tank and water heater

Abstract

The invention belongs to the technical field of household appliances and specifically relates to a vertical water tank and a water heater in order to solve the problems that a lot of water scale is generated easily in a water tank of an existing water heater and the heating efficiency is low. The vertical water tank of the water heater comprises a water storage box and a descaling device arrangedinside the water storage box. The descaling device comprises a supporting part and a cleaning brush arranged on the peripheral face of the supporting part. Under the action of the water temperature orwater pressure in the water storage box, the descaling device can float upwards. The water scale on the inner wall of the water storage box is cleaned through contact friction of the cleaning bush with the water storage box with the inner wall of the water storage box to prevent the heating effect from being affected by the water scale, the heating efficiency can be improved, corrosion to the water storage box is retarded, and the service life of the water tank is prolonged. Moreover, the vertical water tank is provided with the descaling device, there is no need to arrange a power device, and energy consumption is reduced. The vertical water tank is simple in structure and small in size and reduces the installation space of the water heater.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a vertical water tank and a water heater. Background technique [0002] Air energy water heater, also known as "air source heat pump water heater", is a kind of low-temperature heat that absorbs the air. After the fluorine medium is vaporized, the compressor is pressurized and the temperature is raised, the heat is transferred to the water in the water tank through the heat exchanger, so that Get hot water. Air energy water heaters are more and more widely used because of their high efficiency and energy saving. [0003] When the above-mentioned air energy water heater is heating the cold water in the water tank, because the cold water contains a large amount of calcium and magnesium ions, as the water is heated, the calcium and magnesium ions in the water will form calcium carbonate, magnesium hydroxide and other insoluble solids. Substances are precip...
