Sweeping blade structure, cleaning method, controller, air conditioner, internal fan and application

Abstract

The invention belongs to the technical field of design and control, and discloses a sweeping blade structure, a cleaning method, a controller, an air conditioner, an internal fan and its application. Through the improved movement structure of the horizontal sweeping blade, the single-degree-of-freedom movement of the horizontal sweeping blade is changed It is a two-degree-of-freedom movement, and at the same time, the direction control of the horizontal sweeping blades is changed to a double-rod differential control, and the horizontal sweeping is implemented and the sweeping blades are folded to clean the air duct. The sweeping blade structure includes a first pull rod, a second spherical hinge, a sweeping blade, a first spherical hinge, a fixing plate of the sweeping blade, a second pull rod, and a limit baffle. The invention reduces the difficulty of cleaning the air duct of the air conditioner inner unit, and realizes the cleaning function by reducing the disassembly structure. The invention reduces the modification cost, realizes the function by changing the structure of the injection molded part, and reduces the cost increase caused by adding a redundant system. The present invention changes the horizontal sweeping blade into a multi-degree-of-freedom structure so that it can be folded to provide space for air duct cleaning.

Description

technical field [0001] The invention belongs to the technical field of design and control, and in particular relates to a sweeping blade structure, a cleaning method, a controller, an air conditioner, an internal fan and applications thereof. Background technique [0002] In traditional air-conditioning design, in addition to the filter that is most likely to accumulate dust, the air duct at the lower end of the cross-flow fan is also prone to dust accumulation due to long-term wind flowing through and friction with the housing. The self-cleaning technology design of the net, after solving the cleaning of the filter net, the cleaning of the air duct has become the primary problem to be solved. In the current design of the air conditioner internal unit, because one end of the air duct is connected with a cross-flow fan blade, and the other end has a wind deflector and horizontal sweeping blades, so the wind deflector and horizontal sweeping blades need to be removed before cl...
