Abstract

The invention relates to a household normal-pressure heat-pump water heater. The household normal-pressure heat-pump water heater comprises a heat-preservation water tank, a heat exchanger, a heat-pump system, an electric three-way adjustment valve, a water pump, a flow sensor and water level sensors. The electric three-way adjustment valve is provided with an end opening (a), an end opening (b) and an end opening (c). The end opening (a) communicates with the heat-preservation water tank; the end opening (b) communicates with an inlet of a water flow channel through the water pump; and the end opening (c) communicates with a water inlet pipe. The flow sensor is arranged at the end opening (b). The water level sensors are located inside the heat-preservation water tank. A pressure switch,a water flow switch and a hot water outlet pipe are arranged between a water outlet of the heat-preservation water tank and the end opening (a). The household normal-pressure heat-pump water heater can be combined with the water level, the water pressure and the water flow to control the water pump, and cyclic heating operation is achieved; and the water flow velocity can also be controlled through the electric three-way adjustment valve so that water entering the heat exchanger can be heated to the set temperature and stored into the heat-preservation water tank, and therefore, the water outlet temperature and the water pressure can be constant.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a household normal pressure heat pump water heater. Background technique [0002] Chinese Patent No. CN201020209345.5 disclosed a heat pump water heater on January 26, 2011, including a main unit, a heating water tank, and a water storage tank. The main unit and the heating water tank are connected to each other with a water outlet pipe and a water inlet pipe. Circulating water pump, the water inlet pipe is connected with a three-way valve, and the water storage tank is connected to the three-way valve through a connecting pipe. When the temperature of the water outlet of the main unit reaches the set temperature, the water in the heating water tank is heated by the main unit while being pumped. to the storage tank. The disadvantage of this structure is that it is bulky and expensive. Contents of the invention [0003] The purpose of the present invention is t...
