Directly-heated water tank inner container of air energy water heater

Abstract

The invention discloses a directly-heated water tank inner container of an air energy water heater, relates to the field of directly-heated inner containers, and provides the following scheme to solvethe problems that scale is easily generated in an existing heating inner container; and under the impact of high-temperature cold and hot water for a long time, an inner container material is prone to embrittlement, cracking and shelling, so that corrosion and water leakage are caused, and the service life is short. The directly-heated water tank inner container comprises a box body, the box bodyis formed by casting a metal material, a refrigerant inlet, a refrigerant outlet, a temperature detection port, a cold water inlet, a hot water outlet, a circulating inlet and a circulating outlet are respectively connected to one group of side surface of the box body, and a refrigerant heating coil is arranged in the box body. The directly-heated water tank inner container is novel in structure,and the inner container is integrally cast, so that water is not stored, and water leakage is avoided; the inner container does not need to resist impact; hot water can be used immediately after being started, water mixing is avoided, and mildewing and bacterium breeding are avoided; harmful components are not contained, and discharged water can be drunk; water flow resistance is small, water outflow is smooth, and spraying is powerful; and the service life is long.

Description

technical field [0001] The invention relates to the field of direct heating inner tanks, in particular to a direct heating water tank inner tank for an air energy water heater. Background technique [0002] With the continuous improvement of people's living standards, a large number of urban and rural houses of various styles have emerged, and domestic water heaters have also developed rapidly and are constantly being updated. Water heaters have become a household necessity for ordinary people. Recently, the policy support of government departments has been increasing, and at the same time, it has begun to advocate more energy-saving and environmental protection, which has led to the rapid development of air-energy water heaters. Then choose an air-energy water heater. From the perspective of its structure, the "liner" of the water tank is undoubtedly one of the most important parts. Generally speaking, the damage of the water tank liner of the air source water heater is di...

AI Technical Summary

Problems solved by technology

Stainless steel liner: high strength, good temperature resistance, relatively corrosion resistance, stable performance, but difficult to cast, welds are easy to corrode and cause leakage, and easy to scale

Enamel liner: The enamel on the surface is neither rust nor corrosion resistant, and has strong pressure resistance; but it is prone to fish scale explosion, high temperature acid corrosion and dissolution, scale formation, and impact porcelain cracks, which is not conducive to transportation, installation

Crystal liner: corrosion-resistant, anti-scaling, anti-leakage, prolonging the life of the liner, but under the long-term impact of high temperature cold water, the material of the liner will still become brittle, crack, and peel off, resulting in corrosion and water leakage Phenomenon, it is difficult to meet the needs of consumers for high quality and long service life
