Multi-stage self-adaptive household heat pump water heater

Abstract

The invention relates to a multi-stage self-adaptive household heat pump water heater which comprises a hot water tank and an air source heat pump water-heating unit, wherein a main condenser close to the bottom of the hot water tank and an auxiliary condenser close to the top of the hot water tank are arranged in the hot water tank, the auxiliary condenser comprises a water inlet and a water outlet which are positioned at the upper part of the hot water tank and are arranged in the same horizontal position, the water inlet is arranged in the hot water tank, a pipeline at the water outlet of the auxiliary condenser is provided with an outlet water temperature probe, the main condenser and the auxiliary condenser are connected with the air source heat pump water-heating unit through fluorine transmission pipelines, the fluorine transmission pipeline of the main condenser is provided with a main electromagnetic valve, and the fluorine transmission pipeline of the auxiliary condenser is provided with an auxiliary electromagnetic valve. The heat pump water heater can prevent the temperature of hot water from being reduced as a result which is a great amount of cold water filled into the confined water tank at the end of a bath and kept the stable temperature of supplied water, thereby improving bathing comfort and convenience.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a household heat pump water heater, in particular to a multi-stage self-adaptive household heat pump water heater. Background technique [0002] Heat pump water heaters can provide sanitary hot water for families, bathing centers and other occasions. Due to their obvious energy-saving effect, they have developed rapidly and been widely used. At present, the heat pump water heaters used in households have an energy-saving effect of 30% to 70%. They are environmentally friendly and safe, and can realize the function of multi-point simultaneous water supply. They are not affected by sunny or rainy weather conditions, and the installation location is flexible. [0003] Household heat pump water heaters generally adopt an integral structure, the lower part is a circular water tank, and the condenser has two layout forms: one is built-in, the condenser is in the water storage tank, ...

AI Technical Summary

Problems solved by technology

[0004] However, whether it is a built-in or an external household heat pump water heater, there is the same problem, that is, when the bath is finished quickly, because the pressurized water tank is replenished with a large amount of cold water, the hot water supplied cannot meet the bathing temperature requirements, making The bather cannot finish washing, otherwise, when bathing in low-temperature hot water, it is very easy for the bather to catch a cold and get sick
