Indoor air conditioner with inlet and outlet closing door and operation method

Abstract

A room air conditioner includes an air inlet, an air outlet, a heat exchanger disposed between the inlet and outlet, and an air circulation fan. The inlet is opened and closed by motor-driven inlet vanes. The outlet is opened and closed by a vertically slidable motor-driven door. Air direction control vanes extend across the outlet for varying the direction of discharged air. Before the door is either opened or closed, the air control vanes are automatically swung upwardly to a clearance position to avoid interfering with movement of the door. When the inlet and outlet are to be closed, the inlet vane motor is actuated prior the door motor to ensure that the inlet and outlet are fully closed simultaneously, even though it takes longer for the inlet vanes to travel to their fully closed state. A sensor determines when the door reaches an almost-closed state, and the door motor continues to operate for a set period thereafter to ensure that the door becomes fully closed.

Description

technical field [0001] The invention relates to an air conditioner and an operating method thereof. Background technique [0002] Such as figure 1 and 2 As shown, an air conditioner according to the prior art includes: a suction grille 5, which is composed of a group of suction inlets 3 for sucking indoor air, and is arranged on the bottom of the indoor unit body 1 (hereinafter referred to as the body). The lower position, and an exhaust outlet 7, are located at the upper position of the front surface of the body 1, and are used to discharge heated or cooled air indoors when passing through the air conditioner. [0003] The exhaust outlet 7 is provided with a horizontal vane 9 swinging along a horizontal axis for vertically adjusting the flow direction of the air exhausted into the room, and a vertical vane 11 rotating along a vertical axis for horizontally adjusting the flow direction of the air. [0004] The air conditioner is provided with an exhaust outlet door 13 to ...

AI Technical Summary

Problems solved by technology

[0017] However, there is a problem in the conventional air conditioner of this structure that the suction inlet 3 is opened all the time, even when the air conditioner is not in operation, so that dust, foreign substances, etc. enter the body 1 and deposit on the on the surface of the heat exchanger and thus degrades its performance

[0018] Another problem that exists is that when the air conditioner is switched off, the vertical vanes 9 are randomly positioned, which can result in unsatisfactory opening / closing behavior of the exhaust outlet door 13 due to contact of the door with the horizontal vanes 9 problems, and may result in damage to components or misoperation resulting from

[0019] There is another problem that when the upper part of the body 1 is subjected to a heavy load or the like and thus presses the upper area downwards, the range of upward movement of the exhaust outlet valve 13 is limited due to deformation of the components

As a result, the exhaust outlet door 13 may not be pushed far enough for the door open / close sensor to detect the open / close operation of the exhaust outlet door 13, and thus cause errors
