Description

TECHNICAL FIELD The present invention relates to the field of room air conditioners, and in particular to an air conditioner indoor unit. BACKGROUND OF THE INVENTION In the prior art, a vertical air conditioner indoor unit adopts a cabinet shape similar to a rectangular parallelepiped, and the casing is composed of a panel member or the like. The vertical air-conditioning indoor unit comprises an air outlet panel component, an air inlet panel component, a rear casing, an inner component, a top cover and a chassis component, and a fixed assembly form between the components, wherein the lower end of the casing is an air inlet and the upper end is an air outlet. Generally, the air inlet or the air outlet is disposed on the front side or the side surface, and the position of the air inlet or the air outlet is fixed except that the air outlet blade can swing. At the same time, the vertical air conditioner indoor unit, because of its large size, is usually only suitable for models with large refrigeration and heating capacity, and cannot be flexibly applied to smaller models. Further, another vertical air conditioner indoor unit is generally column-like, the lower end is a base and a bottom plate respectively, and the middle end is a main body part and a left side plate assembly right side plate assembly and a moving part, wherein the outer casing includes an air outlet and an air inlet The upper end is a top cover assembly, and the side is a left side plate assembly and a right side plate assembly; when the vertical air conditioning indoor unit is not in operation, the inner air inlet and the inner air outlet are hidden in the left side plate assembly and the right side plate assembly on both sides, When in operation, the inner air inlet and the inner air outlet drive the inner casing to rotate 90 degrees with the moving parts to realize the air outlet and the air inlet function respectively on the front and the back, and the fluid performs cooling or heat exchange through the inner parts, thereby achieving air conditioning. Features. The plate assemblies on both sides of the vertical air conditioner indoor unit generally adopt a circular door panel structure to rotate left and right to make a circular motion, or a wing-like opening structure on both sides of the rear fulcrum. Thus, the vertical air conditioner indoor unit of the prior art has a single outer shape and does not meet the requirements of the personalized product. SUMMARY OF THE INVENTION The object of the present invention is to provide an air conditioner indoor unit which has novel structure, is rich in variation, satisfies the requirements of individualized products, and is suitable for different cooling and heating capacity models. The present invention is achieved by the following technical solutions: an air conditioner indoor unit includes a main body member and an outer casing, the main body member is provided with an air inlet and an air outlet; the outer casing is located outside the body member, and the feature thereof The outer casing includes a left door panel assembly and a right door panel assembly; the left door panel assembly and the right door panel assembly are all connected with a group of more than one driving component; When the power is turned on, the driving component drives the left door panel assembly and the right door panel assembly to open backward from the left and right sides with an involute trajectory. The beneficial effects of the present invention are as follows: The air conditioner indoor unit of the present invention has an involute door panel opening structure, that is, the right door panel assembly and the left door panel assembly adopt an involute motion mode, and the whole machine is a regular whole when the door panel is closed. When opening, move backwards and open to both sides to ensure that the air inlet is not blocked to affect the air intake, and the air outlet is exposed to achieve the air outlet function. Further: the beneficial effects of the opening of the involute track are as follows: The opening of the door plate of the general circular motion track will block the area of the air inlet behind a part of the air conditioner, and the opening of the involute path will not block the area of the air inlet, but also increase Great wind effect. The technical solution provided by the present invention is to break through the above-mentioned conventional framework and provide a new type of cabinet internal machine structure, thereby achieving a new space and height for developing a cabinet machine, which is lighter, more technologically advanced, and cost-effective than a conventional room air conditioner.
