Description

Indoor unit of vertical air conditioner

Technical Field

The utility model relates to the technical field of air conditioners, in particular to a vertical air conditioner indoor unit.

Background

The vertical air conditioner indoor unit comprises a main body, wherein the main body comprises a first cavity and a shell which are arranged in the main body, a heat exchange air inlet and a heat exchange air outlet are formed in the shell, and the heat exchange air inlet and the heat exchange air outlet are communicated with the first cavity. The main body further comprises an indoor heat exchanger and a heat exchange fan, the indoor heat exchanger and the heat exchange fan are arranged in the first cavity, the heat exchange fan is arranged on the front side of the indoor heat exchanger, under the driving of the heat exchange fan, indoor air enters the first cavity from the indoor air inlet, and after the indoor air entering the first cavity exchanges heat with the indoor heat exchanger, the indoor air flows out from the heat exchange air outlet.

The air outlet of the indoor unit of the vertical air conditioner is lower, people can be blown directly frequently, the air guide blades can be arranged in the air duct and connected through the connecting rod, when the air conditioner cools, the air guide blades swing upwards, so that the air guide blades guide the air upwards, and when the air conditioner heats, the air guide blades swing downwards, so that the air guide blades guide the air downwards; the wind guide blade can be driven to rotate so that wind does not blow people as directly as possible.

In the existing design, the wind guide blades connected with the same connecting rod are generally arranged in parallel, and when the connecting rod moves, the wind guide blades connected with the moving connecting rod are always kept parallel to each other in the rotating process, so that the rotating angles of the wind guide blades are the same, and the wind guide directions of the wind guide blades are the same. When the region with the direct blowing people at the lower part of the air outlet wants to realize the direct blowing prevention, the area of the air outlet which is blocked by the air guide blades at the lower part is large, and as the air guide directions of the air guide blades are the same, the upper part of the air outlet is blocked by the air guide blades by a larger area, so that the air output at the upper part of the air outlet is less, and the refrigerating capacity of the air conditioner is influenced; in contrast, in order to ensure the air output of the air outlet, the area covered by the air guide blades is small, and the air guide direction of the air guide blades is the same, so that the direct blowing prevention function of the lower part of the air outlet is weaker, people still can be directly blown at the lower part of the air outlet, and the user experience is poor; because the wind guiding direction of the wind guiding blades is the same, the wind outlet direction is single.

When the upward swing angle of the air guide blade reaches a certain value, the air guide connecting rod interferes with the air guide blade to enable the air guide blade to be incapable of continuously swinging upwards, so that the upward swing angle range of the air guide blade is smaller; when the swing angle of the wind guide vanes is smaller, a certain gap exists between two adjacent wind guide vanes, and wind leaks between the two wind guide vanes due to the existence of the gap, so that the effect of preventing the wind guide vanes from direct blowing is poor.

The place position of wind-guiding blade has unreasonable place, and wind-guiding blade place position is nearer to heat transfer fan, easily produces abnormal sound, and makes the clearance department between preceding volute tongue and the wind-guiding blade easily take place the air leakage, and the wind of spilling can not be blocked by the wind-guiding blade and also can not be by the wind-guiding blade direction for wind-guiding blade prevent that the direct blowing effect and wind-guiding effect are relatively poor.

When the wind guide blade keeps off wind, the temperature difference between the two sides of the wind guide blade, which are close to the air outlet and far away from the air outlet, is easy to be larger, and the condensation effect is easy to be generated on the wind guide blade.

Therefore, the application provides a vertical air conditioner indoor unit.
