Abstract

The invention discloses an explosion-proof air conditioner. The explosion-proof air conditioner comprises an outdoor unit (100) and an indoor unit (200); a flame-proof box component (5) is arranged inside the outdoor unit (100); the flame-proof box component (5) comprises an outdoor intrinsic safety type control main board (4), wherein a safety gate circuit is integrated inside the outdoor intrinsic safety type control main board (4); an increased safety box component (11) and an indoor intrinsic safety type control main board are arranged inside the indoor unit (200); the increased safety box component (11) is connected with the flame-proof box component (5); the indoor intrinsic safety type control main board comprises an intrinsic safety type display (14), and one end of the intrinsic safety type display (14) is connected with the outdoor intrinsic safety type control main board (4). By virtue of the explosion-proof air conditioner, the security and the reliability of the explosion-proof air conditioner can be higher.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an explosion-proof air conditioner. Background technique [0002] Existing explosion-proof split-type air conditioners (including cabinet units and split-type units) carry out explosion-proof treatment on some components on the basis of ordinary household split-type air conditioners. Type explosion-proof technology. The indoor unit is equipped with a strong current main board and a weak current display board. The strong current main board includes many strong current components such as motors, wiring boards and capacitors. The external safety barrier is isolated to make it meet the requirements of intrinsically safe circuits, and the structure is complex. In addition, the outdoor unit is equipped with an intrinsically safe controller for pressure detection and has no exhaust temperature sensing function; the motor and solenoid valve coil adopt explosion-proof technology, which i...
