Problems solved by technology

The heat exchangers are all in the form of flat plates or V-shaped, and all of them need to enter the air from the back or the front of the cabinet, resulting in low utilization efficiency of the heat exchanger, and the air duct structure formed with the cross-flow wind wheel cannot be optimal. And due to the installation form of the cabinet machine, the air intake from the back is too low, or the cabinet machine cannot enter the air at all when it is installed against the wall, which greatly affects the heat exchange capacity of the heat exchanger and lacks practical value

Abstract

The invention relates to a floor type air conditioner indoor machine which comprises an upper frame arranged on a machine body. Heat exchangers, cross flow wind wheels and an air duct for accommodating the heat exchangers and the cross flow wind wheels are arranged in the upper frame, and air inlets and an air outlet communicated with the air duct are arranged on the upper frame. The cross flow wind wheels comprise a left cross flow wind wheel and a right cross flow wind wheel arranged along the horizontal direction. The heat exchangers comprise a left heat exchanger and a right heat exchanger arranged along the horizontal direction, the left heat exchanger is arranged around the left cross flow wind wheel, the right heat exchanger is arranged around the right cross flow wind wheel, and the left heat exchanger and the right heat exchanger are respectively in arc bending shape. The air inlets comprise a left air inlet and a right air inlet, and the left air inlet and the right air inlet are respectively arranged on the left side and the right side of the upper frame, wherein the air outlet is the first air outlet, and a first wind guide vane group is arranged in the first air outlet. The invention has the characteristics of simple and reasonable structure, small complete machine size, low manufacturing cost, high energy efficiency ratio and wide application range and is flexible for operation.

Description

technical field [0001] The invention relates to a floor-standing air conditioner indoor unit. Background technique [0002] Traditional floor-standing air-conditioning indoor units, such as attached figure 1 - attached figure 2 As shown, it adopts a single centrifugal wind wheel structure. In order to increase the heat exchange area, it is often realized by increasing the thickness of the fuselage, increasing the width or height of the fuselage. When the size of the fuselage is increased, the aesthetics of the product will be reduced, and the wind speed of different parts of the heat exchanger will vary greatly, which will not give full play to the heat exchange performance of the heat exchanger. When the air volume is increased by increasing the speed of the wind rotor, problems such as increased noise are caused. [0003] Simultaneously other similar cabinet indoor units that use double cross-flow wind wheels, disclosed a kind of double cross-flow split body floor type...
