Air conditioner with top cover lifting device

Abstract

The invention discloses an air conditioner with a top cover lifting device. The air conditioner with the top cover lifting device comprises a machine casing, a top cover, a first rack, a second rack, a first driving motor and a second driving motor, an air duct is formed in the machine casing, the top of the machine casing is open, and an air inlet commutated with the air duct is formed in the machine casing. The top cover can vertically and movably arranged at the top of the machine casing, and an air outlet communicated with the air duct is formed in the top cover. The first rack and the second rack are connected with the top cover so as to drive the top cover to vertically move. The first driving motor and the second driving motor are installed on the machine casing, a first motor shaft of the first driving motor is provided with a first gear meshed with the first rack to drive the first rack to vertically move, and a second motor shaft of the second driving motor is provided with a second gear meshed with the second rack to drive the second rack to vertically move. In the air conditioner, vertical movement of the top cover is controlled through meshing of the gears and the racks, and accordingly the top cover is stable in lifting. In addition, the air conditioner is simple in structure.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner with a top cover lifting device. Background technique [0002] In recent years, in the field of air conditioning, mid-to-high-end products have gradually appeared in the air-conditioning field with lift-off doors, sliding doors, and top air outlets. The air outlet can be closed, which greatly improves the appearance and market competitiveness of the product. [0003] In the current air-conditioning industry, the top air outlet structure of the split floor-standing air conditioner uses a foldable bracket to drive the lifting movement of the top cover of the air conditioner. The hinge of the foldable bracket does not move relative to the foldable bracket, and acts as a fixed support point. When the foldable bracket is working, an external rotational moment can act on the hinge, so that the connecting rod at the hinge rotates. Among them, the foldable bracket can...

AI Technical Summary

Problems solved by technology

Among them, the foldable bracket can be driven up and down by a drive motor. This structure has the following disadvantages: 1. The connecting rod at the hinge is rotated by applying an external rotational torque on the hinge, and the drive motor pushes the entire foldable bracket to move from one point of the hinge. , the drive motor is a high-power motor. The high-power drive motor has a lot of noise and severe vibration during operation, which makes the folding bracket not slide smoothly under the action of rigid force; 2. The folding bracket is connected by the hinge points on both sides of the bracket Rail connection requires a high degree of cooperation between each hinge point and the slide rail. The installation process is cumbersome and the production efficiency is low. It is not suitable for industrial production.

As a result, the top air outlet structure of the split floor-standing air conditioner is complicated and the operation is unstable
