Air conditioner

Abstract

The invention provides an air conditioner. The air conditioner comprises an air outlet grid, the air outlet grid comprises multiple annular grids which are coaxially arranged, and the annular grids are connected through multiple radial grid bars which are arranged in the radial direction of the annular grids. The radial grid bars comprise flow guide sections used for guiding airflow blown out of afan and flow adjusting sections used for adjusting the guided airflow to enable the airflow to flow out towards the position of the center of the fan, and the flow guide sections are connected with the flow adjusting sections. The annular grids comprise the first annular grids, and the heights of the first annular grids are gradually increased in the radial direction from the center of the fan tothe outer edge of the fan. According to the air conditioner, the air speed of air blown out by the fan of the air conditioner can be effectively increased, the divergence angle of the blown-out air can be reduced, the backflow amount of the blown-out air is greatly reduced, and the performance of the air conditioner is guaranteed.

Description

technical field [0001] The invention relates to an improvement of the structure of an air conditioner. Background technique [0002] In order to reduce the safety risk of air-conditioning equipment installation and subsequent use, and at the same time meet the requirements of the aesthetics of the building facade, the split-type air conditioner is used as an example to illustrate that most buildings do not allow the outdoor unit of the air conditioner to be directly hoisted on the building. exterior wall. Instead, it is required to install the outdoor unit of the air conditioner on the special equipment platform reserved for the building. In order to maximize the actual use area of ​​the building, the special installation platform for the air conditioning equipment reserved for this kind of building is often a balcony or wall. At the same time, blinds should be used to cover the installation places of these special equipment, so that the outdoor unit equipment of the air co...

Instead, it is required to install the outdoor unit of the air conditioner on the special equipment platform reserved for the building. In order to maximize the actual use area of ​​the building, the special installation platform for the air conditioning equipment reserved for this kind of building is often a balcony or wall. At the same time, blinds should be used to cover the installation places of these special equipment, so that the outdoor unit equipment of the air conditioner can hardly be seen from the outside of the building, thus ensuring the aesthetic appearance of the building, such as figure 1 As shown, however, the installation method of this kind of air conditioner outdoor unit is often affected by factors such as the size of the installation platform space, the form of the louvers and the size of the shielding area, the wind field of the air conditioner outdoor unit itself, and the weather environment. As a result, the hot air blown by the fan of the outdoor unit of the air conditioner is difficult to be effectively dissipated during cooling operation in summer, but most of it will be directly absorbed back to the heat exchanger of the outdoor unit of the air conditioner, thereby deteriorating the heat transfer performance of the heat exchanger, such as figure 1 As shown, the cooling mode is taken as an example for illustration. When the air conditioner is installed in the building groove, the angle of the wind blowing from the air outlet grille is relatively divergent, and the wind will blow to the side wall of the building groove. Reflected by the side wall, the hot air is sucked into the air inlet side of the heat exchanger, which reduces the heat transfer performance of the heat exchanger, resulting in a decrease in the cooling effect. When the temperature is low, most of the hot air blown from the outlet grille around the outdoor unit will enter the interior of the outdoor unit, forming a backflow of air, especially when the weather is relatively hot, this problem is more serious
