Description

An air conditioner cabinet indoor unit

technical field

The utility model belongs to the technical field of an air conditioner cabinet, in particular to an indoor unit of an air conditioner cabinet.

Background technique

Ordinary cabinet-type air conditioner indoor units generally use centrifugal fans and cross-flow fans for heat exchange, which are characterized by small circulating air volume and small air inlet area, and the installation of the entire air supply system is inconvenient. Road, so the installation volume is large, and the size of the entire indoor unit is large. For the structure of the cabinet type indoor unit equipped with axial flow fans, the axial flow fan system is installed inside the indoor unit. Due to the large volume and weight of the axial flow fan, the fixing method is also complicated. Usually, the motor bracket is used to align the shaft. The flow fan system is fixed, resulting in increased air duct resistance, affecting air volume and heat transfer. For cabinet air conditioners equipped with multiple axial flow fans, defects such as turbulent flow, abnormal sound, and uneven heat transfer effect are prone to occur.

detailed description

The technical solutions of the present utility model will be described in further detail below in conjunction with specific embodiments.

As shown in FIG. 1 , this embodiment provides an indoor unit of an air conditioner cabinet, which includes upper and lower parts, namely an upper housing 10 and a lower housing 20 , which together form the external supporting housing of the indoor unit. The back and sides of the upper housing are provided with a hollow structure as an air inlet; the front of the upper housing is connected to a panel 30; as shown in Figure 2, the panel is provided with two axial flow fans distributed up and down. Hole 31, as air outlet.

An axial flow fan 40, a heat exchanger 50 and a water tank 60 are installed in the upper housing 10 of the indoor unit; the axial flow fan 40 is embedded in the axial flow fan installation hole 31 on the panel , and use bolts for fixing (bolt holes 33 can be provided on the panel), that is, the two axial flow fans are directly installed on the panel of the cabinet air conditioner, which can reduce the volume of the upper shell. The heat exchanger 50 is located at the air inlet end of the axial flow fan and is perpendicular to the air inlet direction, which can increase the heat exchange area and improve the heat exchange efficiency. The water receiving tank 60 is located at the bottom of the upper housing, and is installed on the frame of the upper housing, such as using screws or welding; the water receiving tank is connected to a drain pipe to discharge the generated condensed water.

In the indoor unit structure of this embodiment, the axial flow fan is installed on the panel of the upper casing as the air outlet, the back and side of the upper casing are covered with hollow structures as the air inlet, and the heat exchanger It is installed between the air inlet and the axial flow fan, so that the air inlet direction is perpendicular to the heat exchanger, which effectively increases the air supply volume, improves heat exchange efficiency, and reduces indoor noise at the same time.

As a preferred embodiment, the air outlet end of the axial flow fan is provided with a sleeve 41, and the sleeve is a hollow cylinder with the same diameter as the installation hole of the axial flow fan and a length of 100-110 mm. The sleeve plays the role of collecting wind, preventing the blown wind from diverging to the surroundings, so that the distance of the wind blowing is longer.

A preferred heat exchanger adopts a flat plate bending structure, which can effectively improve the heat exchange efficiency of the heat exchanger.

An electric control assembly 80 and a compressor assembly 90 are installed in the lower shell of the indoor unit, and the electric control assembly is located outside the compressor assembly. The electric control assembly is used to control the entire refrigeration system. The compressor assembly is a refrigeration assembly including a compressor, an electronic expansion valve, a four-way valve, and the like.

In this embodiment, the axial flow fan is embedded on the panel of the upper casing, and the panel can also be used as a bracket supporting the axial flow fan, which is convenient for installation. The heat exchanger is installed between the rear air inlet and the axial flow fan, and then the electric control assembly and the compressor assembly are arranged in a separate space (lower housing), which makes the structural layout of the entire indoor unit more compact. At the same time, there is no need to place a compressor in the outdoor unit of the air conditioner, so that the volume of the outdoor unit is reduced, which is conducive to reducing the cost.

The indoor unit of the air conditioner cabinet also includes a display, which is used as a display device for the operation panel of the whole machine and various information, and is embedded in the display installation hole 32, and the display installation hole is located on the panel. For the sake of appearance, it can be arranged between the upper and lower axial flow fan installation holes.

As a preferred embodiment, an air duct partition is provided between the upper and lower axial flow fans, and is installed on the frame of the upper casing, for example, by using screws or welding. The area of the air channel partition is the same as the cross-sectional area of the upper casing, which effectively avoids the phenomenon of turbulent flow in the flow field.

The above embodiments are only some of several preferred implementation modes of the present invention. It should be pointed out that the present invention is not limited to the above embodiments; Modification of the scheme, or equivalent replacement of some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution claimed by the utility model.
