Vertical insulation water tank and air energy water heater

Abstract

The invention provides an upright thermal insulation water tank and an air energy water heater. The upright thermal insulation water tank comprises a box body, a cold water inlet, a hot water outlet and a partition plate assembly arranged in the inner cavity of the box body; the partition plate assembly can move in the inner cavity of the water tank up and down; the outer edge of the partition plate is abutted against the side wall of the box body; the partition plate assembly divides the inner cavity of the box body into an upper cavity and a lower cavity; the cold water inlet is formed in the inner wall of the lower cavity; the hot water outlet is formed in the inner wall of the upper cavity. The partition plate assembly is arranged in the water tank of the upright thermal insulation water tank, hot water and cold water are isolated by the partition plate assembly, and replenished cold water is not fully mixed with the hot water, so hot water output rate is prevented from being reduced after the hot water and the cold water are mixed; ineffective energy consumption is reduced by the arrangement, the energy saving effect is improved, and the energy is saved by about 15% compared with that of the existing water tank.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a vertical thermal insulation water tank and an air energy water heater comprising the vertical thermal insulation water tank. Background technique [0002] At present, the water tanks used in water heaters are generally ordinary pressure-bearing heat-insulating water tanks (vertical). This type of vertical ordinary pressure-bearing heat-insulating water tanks usually enters tap water (cold water) from the lower end and hot water from the upper end. The inside of the water tank is directly connected. Cold water is added to the hot water at the same time, and the cold water is directly mixed with the hot water inside. [0003] Since the supplementary cold water will mix with the hot water after entering the water tank, the heated hot water cannot be effectively discharged, thereby reducing the hot water output rate of the water tank and wasting the heated hot water; The temperature o...

Problems solved by technology

[0003] Since the supplementary cold water will mix with the hot water after entering the water tank, the heated hot water cannot be effectively discharged, thereby reducing the hot water output rate of the water tank and wasting the heated hot water; The temperature of the cold water rises, and when the water heater starts to boil water again, it starts to heat up from the mixed water temperature. One of the biggest disadvantages of the air-energy water heater is that the higher the water temperature, the lower the energy efficiency, which will cause the air-energy water heater to boil water again. The energy efficiency decreases; the cold water entering the water tank may be mixed with hot water and then directly discharged from the hot water outlet, so the hot water is discharged at the beginning, and the mixed warm water is discharged later, and there is a situation of being hot first and then cold

This causes great inconvenience to the user, and also reduces the energy efficiency of the air energy water heater
