[0002]
The evaporator of the air conditioner is connected by multiple evaporator sheets. When the air flow passes through the surface of the evaporator, it achieves the purpose of cooling through heat exchange. However, there are gaps between adjacent evaporators, and the air flow will pass through the gap. into the evaporator, which will reduce the heat transfer efficiency of the evaporator
[0003] In existing evaporators, sealing strips are generally installed at the joints of the evaporator sheets to prevent airflow from entering the interior. However, when the air conditioner is cooling, the evaporator of the indoor unit will generate a certain amount of condensed water. If the condensed water cannot be discharged quickly and effectively, Condensed water will be adsorbed on the surface of the evaporator and the sealing strip, which will also reduce the heat exchange efficiency of the evaporator, and even cause water leakage of the indoor unit, which puts forward high requirements on the drainage capacity of the evaporator
[0004] Although the existing air-conditioning evaporator is provided with a drainage structure, there is no specific drainage structure at the connection of the evaporator, but a sealing strip or hot melt adhesive is provided at the bending part of the evaporator, although the sealing performance is increased, but Does not increase the drainage capacity of the evaporator

Embodiment Construction
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples cited are not intended to limit the present invention.
[0022] Such as figure 1 , figure 2 with image 3 Shown is the drainage structure diagram of the evaporator of the indoor unit of the air conditioner of the present invention. The bottom of the evaporator 7 is provided with a water receiving pan 1, and a windshield 6 is provided at the gap between the two evaporators 7. The windshield 6 is provided with a hole 61, and the water collecting part of the windshield 6 is in communication with the water receiving tray 1.
[0023] The drainage mechanism also includes an upper drainage groove 2 which cooperates with the windshield 6. When the evaporator 7 performs heat exchange operation, the condensate generated at the connection of the evaporator...

The invention discloses a drainage structure of air conditioner indoor unit evaporators, the air conditioner indoor unit evaporators and an air conditioner. A water receiving tray is arranged on the bottom of each evaporator, a draught strip is arranged in a gap between two evaporators, holes are formed in the draught strip, and the water collecting part of the draught strip is communicated with the water receiving tray. According to the drainage structure of the air conditioner indoor unit evaporators, the air conditioner indoor unit evaporators and the air conditioner, the draught strip structure is arranged between the evaporators, condensate water is collected and effectively discharged in time, the heat exchange efficiency of the evaporators is improved, and matching of the bended parts of the evaporators is enhanced.
Description
Technical field [0001] The invention relates to a drainage structure of an evaporator, in particular to a drainage structure of an evaporator of an air conditioner indoor unit. Background technique [0002] The evaporator of the air conditioner is formed by connecting multiple evaporator pieces. When the airflow passes through the surface of the evaporator, it achieves the purpose of cooling by heat exchange, but there will be gaps between adjacent evaporators, and the airflow will pass through the gaps. Into the evaporator, this will reduce the heat exchange efficiency of the evaporator. [0003] In existing evaporators, sealing strips are generally installed at the joints of the evaporator sheets to prevent airflow from entering the interior. However, when the air conditioner is cooling, the evaporator of the indoor unit will produce a certain amount of condensed water. If the condensed water cannot be discharged quickly and effectively, The condensed water will be adsorbed on t...
