Directly heating heat pump water heater water tank

Abstract

The invention discloses a directly heating heat pump water heater water tank which comprises a water tank body, a tap water inlet, a circulating water pump, a hot water main pipe, a hot water branch pipe, a first electromagnetic valve, a second electromagnetic valve, a plurality of capillaries, a partition, a third electromagnetic valve, a fourth electromagnetic valve and a suction pipe; a cold water outlet is formed in the front side at the lower part of the water tank body; the third electromagnetic valve and the suction pipe are arranged at the part, in the water tank body, of the cold water outlet; the suction pipe is used for sucking water at the upper part of the water tank body, and is arranged in front of the third electromagnetic valve; the fourth electromagnetic valve is arranged on the suction pipe; the input end of the circulating water pump is connected with the cold water outlet; the output end of the circulating water pump is connected with a lateral circulating water inlet in a condenser; and a lateral circulating water outlet in the condenser is connected with a hot water inlet in the front at the upper part of the water tank body. Compared with the prior art, the directly heating heat pump water heater water tank has good diversion effect, less circulation heat dissipation, stable temperature field, small system pressure fluctuations, low cost, and simultaneous heating and water supplying function.

Description

[0001] 【Technical field】 [0002] The invention relates to a water tank of a water heater, in particular to a water tank for direct heating air source heat pump water heaters operating under low temperature conditions in winter. [0003] 【Background technique】 [0004] With the rapid development of the economy and the continuous improvement of people's quality of life, consumers' requirements for the use of air source heat pump water heaters are also increasing. Among them, the requirements for continuous use of hot water and shortening the waiting time for reusing hot water are also becoming more and more significant. The direct heating air source heat pump water heater unit is a unit that can directly heat water to the required temperature. It has the characteristics of large temperature difference and small flow rate, and the hot water produced by the unit can be used directly. During the operation of the direct heating unit, the high pressure is stable and the water is rele...

AI Technical Summary

Problems solved by technology

The hot water in the traditional water storage tank will naturally rise due to the difference in density and pressure caused by its own temperature during the flow process, resulting in obvious stratification and uneven mixing of hot and cold water, and at the same time causing low-temperature dead ends in the water tank, making Uneven temperature distribution inside the tank
