Description

TECHNICAL FIELD The invention belongs to the field of air conditioning technologies, and in particular, to a ducted air conditioner and an assembly method thereof. BACKGROUND A ducted air conditioner is an indoor unit of the air conditioner, which is connected to an outdoor unit of the air conditioner through a copper pipe. The ducted air conditioner blows cold air or hot air directly to each room through an air duct. Due to a hidden installation of the ducted air conditioner, it has less effect on the aesthetically pleasing of the room and an advantage of a simple structure, which makes the maintenance convenient, so it is widely used. Due to an increase in a demand of the ducted air conditioner, an improvement on a production efficiency of the ducted air conditioner is imminent. At present, an existing ducted air conditioner is composed of separate components assembled through screws. Accordingly, a large number of screws are used for fixing in a production process, resulting in a high labor consumption and a low efficiency. Moreover, the ducted air conditioner has a large number of components, and assembly steps thereof are complicated, making it difficult to automatically produce the ducted air conditioner. In addition, screw holes of sheet metal members are prone to defects such as misalignment of screw holes and slippery thread of screw holes. In this case, the sheet metal members or the screws need to be replaced, which will further affects the production efficiency, and makes it difficult to meet a large demand of the market. CN 107 192 020 A provides a duct type air conditioner. The duct type air conditioner comprises a shell body, a fan assembly, a volute assembly, a wind duct plate, a heat exchanging assembly and a water receiving plate, wherein the fan assembly, the volute assembly, the wind duct plate, the heat exchanging assembly and the water receiving plate are arranged in the shell body. The volute assembly comprises a foaming shaped upper volute and a foaming shaped lower volute. The wind duct plate and the upper volute are integrated foaming shaped pieces. The heat exchanging assembly is arranged below the wind duct plate and is fixed to the shell body. The water receiving plate is arranged under the heat exchanging assembly and clamped on the wind duct plate. The upper volute is snapped on the lower volute and covers the fans. The upper volute, the lower volute, the wind duct plate and the water receiving plate define an enclosed wind duct. A wind outlet of the wind duct is opened towards to the heat exchanging assembly. According to the duct type air conditioner, problems of multiple spare parts and high manufacturing cost in the prior art are solved. EP 3 081 867 A1 relates to a heat exchanger unit comprising a casing defining a duct to be flown through by a fluid, a fan disposed in the casing and configured to induce a flow of the fluid through the duct in a flow direction, a heat exchanger being V-shaped in side view with an apex at one end and an opening at the opposite end. The heat exchanger is disposed in the duct with the opening directed towards the flow direction, wherein a line passing the apex of the V-shaped heat exchanger in the side view extends horizontally, wherein the fan is disposed downstream of the heat exchanger in the flow direction.
