Integral heat pump water heater

Abstract

The invention discloses an integral heat pump water heater, which comprises a machine head, a machine body and a condenser, wherein a compressor, a throttle element and an evaporator are arranged in the machine head, the compressor is provided with an exhaust opening and an air return opening, the evaporator is connected with one end of the throttle element and the air return opening, the machine body is arranged on the machine head and comprises a water tank inner liner and a water tank case, the water tank inner liner is used for containing water, the water tank case is arranged at the outer side of the water tank inner liner, a heat insulation layer is filled between the water tank inner liner and the water tank case, the condenser is provided with a heat exchange coolant flow passage and a water flow path, the two ends of the coolant flow path are respectively connected with the exhaust opening and the other end of the throttle element, the two ends of the water flow path are respectively communicated with a water pipe extending into the water tank inner liner, a water pump is connected in series onto the water pipe, and the condenser and the water pump are detachably arranged in the machine body or the machine head. The integral heat pump water heater has the advantages that the integral machine efficiency can be improved, the copper coil pipe fluorin leakage risk is avoided, the production process of a water tank is simplified, the installing process of the water heater is simplified, and the integral machine cost is reduced.

Description

technical field [0001] The invention relates to the field of household electrical appliance manufacturing, in particular to an integral heat pump water heater. Background technique [0002] Traditional heat pump water heaters are mainly divided into three types: integral fluorine circulation type, split fluorine circulation type and split water circulation type. [0003] Integral fluorine circulation type and split fluorine circulation type heat pump water heaters generally have copper coils around or built-in water tanks, and the copper coils are used as refrigerant flow paths to heat the water in the water heater. The water in the water is still, and the heat exchange efficiency between the refrigerant flow path and the water is low, resulting in low energy efficiency of the whole machine. On the other hand, after long-term use, the copper coil has the risk of fluorine leakage. Once fluorine leaks, the water tank will be damaged. Scrap, and the production process of the w...
