Magnesium rod assembly of water storage type water heater

Abstract

The invention discloses a magnesium rod assembly of a water storage type water heater. The magnesium rod assembly comprises a magnesium rod (1), one end of the magnesium rod (1) stretches into an inner container (7), the other end of the magnesium rod (1) makes tight contact with a magnesium rod base (2), the magnesium rod base (2) make tight contact with the end face of a drain outlet (6), the drain outlet (6) is welded to the inner container (7), and a drain cover (5) matched with the drain outlet (6) is arranged on the outside of the drain outlet (6). The magnesium rod of the magnesium rod assembly makes tight contact with the magnesium rod base, the magnesium rod base makes tight contact with the end face of the drain outlet, the drain outlet is welded to the inner container, the magnesium rod is electrically communicated with the inner container, the structure is simple, assembly and disassembly are convenient, simple transformation only needs to be carried out on an existing magnesium rod assembly, new components do not need to be additionally arranged, cost is low, the magnesium rod assembly is easy to achieve, heat diffusion amount is small, and heat preservation performance of the water heater can be improved.

Description

Technical field [0001] The invention relates to a storage type electric water heater, in particular to a storage type electric water heater magnesium rod assembly. Background technique [0002] Storage type electric water heater refers to a fixed appliance that heats water. It can store hot water for a long time or temporarily, and is equipped with a device to control or limit the water temperature. Storage type electric water heaters are commonly used in households, which are easy to install and low in price, but they need to be heated for a long time and can be used after reaching a certain temperature. [0003] Storage-type electric water heaters are divided into two types according to their outlet types: enclosed electric water heaters and open electric water heaters. The closed electric water heater is controlled by one or more valves at the water outlet and works under the pressure of tap water. This type of water heater has the advantages of flexible installation location,...

AI Technical Summary

Problems solved by technology

When installed on the heating tube flange, it is difficult to replace the magnesium rod; and it is close to the heating tube, which is easy to form scale accumulation and affect the life of the heating tube

When installed at the sewage outlet, in order to make the magnesium rod and the inner tank electrically conductive, the sewage outlet cover needs to be made of metal materials, which makes the cost of the sewage outlet cover high and the heat loss is large
