A heat pump water heater

Abstract

The invention discloses a heat pump water heater, which comprises a casing, a compressor, a heat exchanger, an evaporator group and a fan assembly arranged in the casing, the evaporator group includes a first evaporator and a second evaporator, the first evaporator It is connected to the top of the second evaporator, and the lower end is separated in an inverted V shape; the compressor and heat exchanger are arranged in the cavity of the evaporator group, and a fan assembly is arranged outside the evaporator partition; between the first evaporator and the second An air inlet grill is arranged outside the evaporator, and an outlet grill is arranged outside the fan assembly. Its beneficial effects are: the integral design without water tank can reduce pipeline components, eliminate the hidden danger of leakage during installation, facilitate installation and save space; the inverted V-shaped evaporator can effectively reduce the thickness and height of the unit; the air intake on both sides , The air outlet is obliquely backward, which can not only avoid the short circuit of the air inlet and outlet, but also avoid the discomfort caused by the air outlet facing the crowd; the use of double fans can effectively improve the heat exchange efficiency of the evaporator and reduce the noise of the unit .

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...
