Inner machine of air conditioner

Abstract

The invention discloses an inner machine of an air conditioner, which comprises a housing, an evaporator, a draught fan, and an electric control box, wherein an air inlet and an air outlet are formed in the housing; an air passage communicated with the air inlet and the air outlet are arranged inside the housing; the electric control box is positioned at the outer part, next to the air outlet, of the air passage; and more than one air holes are formed in a baffle between the electric control box and the air passage. According to the inner machine of the air conditioner provided by the invention, the air holes, communicated with the air passage, are formed in the baffle of the electric control box to well solve the condensation problem of the electric control box and avoid the serious humidity environment for electric components, and therefore, the reliability is greatly improved; potential safety hazards, such as short circuit of the electric components, water seepage inside the electric control box and the like are eliminated; and the processing process that the air holes are formed in the baffle is simple.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner inner unit. Background technique [0002] With the increasing popularity of household air conditioners, commercial air conditioners are gradually occupying an important market position, and household air conditioners are also playing an increasingly important role. [0003] The indoor unit of a household air conditioner consists of several parts including the casing, evaporator, fan and electric control box. The indoor unit of a vertical household air conditioner has a bottom air inlet and upper air outlet structure, passing through the evaporator and being resisted by the fins. Finally, the flowing gas becomes cold low-pressure gas, and the cold wind is rotated and pressurized by the fan to form cold high-pressure gas at the air outlet. However, because the electric control box is theoretically located in a closed space and does not participate in the refrigeration cycle...

AI Technical Summary

Problems solved by technology

Since the electric control box is theoretically located in a closed space and does not participate in the refrigeration cycle of the system, it is regarded as a low-pressure side compared to other spaces of the internal unit, and the temperature inside the electric control box is higher than other places, so the electric control box is easy to form condensation. And the closer to the air outlet, the greater the temperature difference, and the more serious the condensation

Condensation for such a long time will cause water seepage of electrical components, which may cause safety problems such as short circuit
