Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an air conditioner. Background Art

[0002] In the air-conditioning industry, air duct guide structures are generally used for air outlets. The most common one is the air sweeping structure of the air outlet of household air conditioners. Some are also used for guiding the air outlet of backward-inclined centrifugal fans, etc. Generally, the air is guided in the direction of the air outlet without the need for guiding the wind speed at different positions.

[0003] Secondly, the traditional heat exchanger uses water to exchange heat and does not involve the control of airflow. However, the new heat exchanger adopts the method of fan blowing and convection heating, and the existing guide structure deflects the wind blown by the fan through the guide channel. However, most of the wind blown by the fan reaches the turning point of the guide channel and is guided into the heat exchanger along the wall of the guide channel, resulting in the wind flowing through the guide channel being on the side close to the wall of the guide channel, which makes the contact area between the wind blown by the fan and the heat exchanger lower, which leads to low heat exchange efficiency of the heat exchanger, which urgently needs to be improved.

[0033] The technical solution of the utility model forms a plurality of guide air ducts 500 by adopting the guide structure 200 and the guide channel 110, and the plurality of guide air ducts 500 are arranged at intervals in the air outlet direction of the fan 400, and the heat exchanger 300 is located at one end of the plurality of guide air ducts 500 away from the fan 400. In this way, the plurality of guide air ducts 500 formed by the guide structure 200 and the guide channel 110 guide the wind blown out of the fan 400 to various parts of the heat exchanger 300, thereby increasing the contact area between the wind blown out of the fan 400 and the heat exchanger 300, thereby increasing the heat exchange efficiency of the heat exchanger 300, thus improving the working efficiency of the air conditioner 1000, and at the same time preventing most of the wind blown out of the fan 400 from impacting the heat exchanger 300 to cause noise, thereby reducing the noise generated by the air conditioner 1000.

[0034] Please also read Figures 1 to 3In some embodiments of the utility model, the guide structure 200 includes a plurality of guide blocks 210, and the plurality of guide blocks 210 are arranged at intervals in the air outlet direction of the fan 400, and the distance between one end of the plurality of guide blocks 210 away from the heat exchanger 300 and the heat exchanger 300 is arranged to increase successively in the air outlet direction of the fan 400.

[0035] With such an arrangement, a plurality of guide air ducts 500 are formed together by a plurality of guide blocks 210 and guide channels 110, so that the wind blown out by the fan 400 can be better guided to various locations of the heat exchanger 300, thereby increasing the contact area between the wind blown out by the fan 400 and the heat exchanger 300. At the same time, the distance between the end of each guide block 210 away from the heat exchanger 300 and the heat exchanger 300 is sequentially increased in the air outlet direction of the fan 400, so that the wind blown out by the fan 400 can sequentially contact each guide block 210 in the direction away from the heat exchanger 300, thereby guiding the wind blown out by the fan 400 to the adjacent guide air duct 500 after contacting the corresponding guide block 210.

[0036] The guide block 210 can be made of many materials, such as metal, hard plastic, or other materials, which are not specifically limited here. The guide block 210 can be integrally formed with the housing 100, or can be detachably mounted on the housing 100, which are not specifically limited here.
