Heat-pump water heater

Abstract

The invention discloses a heat-pump water heater which comprises a shell, and a compressor, a heat exchanger, an evaporator group and fan assemblies which are arranged in the shell, wherein the evaporator group comprises a first evaporator and a second evaporator; the top ends of the first evaporator and the second evaporator are connected, and the lower ends of the first evaporator and the second evaporator are separated, so that inverted V-shaped connection is formed; the compressor and the heat exchanger are arranged in the cavity of the evaporator group; the fan assemblies are arranged outside evaporator partition plates; air inlet gratings are arranged outside the first evaporator and the second evaporator; air outlet gratings are arranged outside the fan assemblies. The heat-pump water heater has the beneficial effects that due to the integrated design without a water tank, pipeline components can be reduced, the potential leakage hazard of a mounting process is avoided, the mounting is convenient, and the space is saved; the inverted-V-shaped evaporators can effectively reduce the thickness and the height of a unit; air is fed from the two sides and is discharged from the back slant direction; therefore air feeding short circuit and air discharging short circuit can be avoided, and the discomfort caused by a fact that the air is discharged towards people can be also avoided; by the adoption of a form with two fans, the heat exchange efficiency of the evaporators is effectively improved, and the noise of the unit is reduced.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a heat pump water heater. Background technique [0002] At present, air energy heat pump water heaters are generally divided into integral type and split type. The split type air energy water heater proposed in the "Air Energy Water Heater" with the patent number of 201110118684 has disadvantages: 1. The split type is similar to the split air conditioner, and it is inconvenient to install. , and it is easy to cause refrigerant leakage during installation; 2. The capacity is generally above 150L, ​​and the water tank is bulky, which consumes a lot of construction area during installation, or it is installed on the wall, and the load-bearing of the wall is quite dangerous; 3. The fan blows to the outside , If the installation distance is relatively close to the neighbors, the wind blown by the fan is likely to affect others; 4. The shape and structure are rigid, and it is easy to be co...
