Abstract

The invention relates to the field of water heaters, and discloses a heat pump water heater. The heat pump water heater comprises an outer shell (6), a bracket (2), an end cover (1) and a filter screen (3). The bracket (2) is provided with a wind opening (2-1). The end cover (1) is spaced apart from the bracket (2) to form an operation opening (4). The filter screen (3) is located between the bracket (2) and the end cover (1) and covers the wind opening (2-1). The bracket (2) is provided with a sliding groove (5), and the filter screen (3) can slide in or out of the sliding groove (5) throughthe operation opening (4). Through the technical scheme, the sliding groove is formed between the bracket and the end cover, the filter screen can be installed in the sliding groove and can slide outor slide into the sliding groove from the operation opening, the filter screen is disassembled and installed without disassembling other structures, the operation is more convenient, and the disassembly, cleaning and replacement of the filter screen are convenient.

Description

technical field [0001] The invention relates to a water heater, in particular to a heat pump water heater. Background technique [0002] Air energy water heaters, also known as heat pump water heaters. The heat exchanger (evaporator) of the air-energy water heater absorbs heat from the air, heats the low-boiling point working medium (refrigerant) and evaporates it. The refrigerant vapor is compressed and heated by the compressor and enters the water tank, releasing heat to the water in it and condensing and liquefying. Then throttling and depressurization lowers the temperature and returns to the outdoor heat exchanger to enter the next cycle. Due to high efficiency and energy saving, air energy water heaters are more and more trusted by users. [0003] The shell of the air source water heater is equipped with an air return port structure through which air can be sucked in. In order to ensure the cleanliness of the inhaled air, a filter needs to be set to filter the air. ...
