Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a base of an air conditioner and an air conditioner having the base. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, air conditioner products have been more and more widely used in more and more occasions. In addition, people have also put forward increasingly higher requirements for various performances of air conditioners.

[0003] At present, air conditioners in the industry use sweeping blades to achieve the function of sweeping air left and right. The drive motors of the sweeping blades in the prior art are all arranged on the left and right sides of the air outlet. This structure has the following defects: since the sweeping blade motors are arranged on the left and right sides of the air outlet, the arm rods that drive the blades to rotate are relatively long, and the required torque will be relatively large. Therefore, the probability of motor failure will increase, especially the longer the air conditioner body and the longer the air outlet, the greater the probability of failure.

[0004] It can be seen from this that the prior art requires an air conditioner that can set the wind sweeping structure drive motor in the middle of the wind sweeping structure, thereby ensuring that the motor runs effectively, the blades swing easily and at a uniform speed, and do not block the air outlet, thereby ensuring smooth air outlet. Summary of the invention

[0005] The problem solved by the present invention is to provide a base of an air conditioner, and by arranging one or more corresponding parts such as a through hole, a hollow boss, a blade connecting plate fixing part, etc. on the base, the driving component and / or the wind sweeping component of the air conditioner can be stably fixed at the corresponding position of the base. The present invention arranges a through hole that can cooperate with the driving component on the base at the lower end of the air outlet, so that the torque required by the driving component when driving the wind sweeping component to sweep the air is reduced, thereby reducing the probability of motor drive failure and improving the stability of the driving component.

[0006] In order to solve the above problems, the present invention provides a base of an air conditioner and an air conditioner having the same. The present invention is implemented in the following manner.

[0007] A base of an air conditioner is provided with a through hole, the through hole is located at the lower end of an air outlet of the air conditioner, a driving assembly is installed below the through hole, the driving assembly includes a crank, and the crank extends into and passes through the through hole.

[0008] Since the present invention has a through hole in the middle of the base, the present invention can set the driving component for driving the wind sweeping blade on the base, and the crank of the driving component passes through the through hole, extending from the back side of the base into the front side of the base, and the motor located on the back side of the base drives the wind sweeping blade located on the front side of the base. Therefore, the present invention can ensure the effective operation of the motor by setting the driving component on the base and setting a through hole structure for the crank of the driving component to pass through at the corresponding position of the base, and since the position of the through hole is set at the lower end of the air outlet of the air conditioner, the driving component will not block the air outlet, and the smooth air outlet of the air conditioner can be ensured.

When in use, the limiting protrusion is aligned with the limiting part, and the crank is slightly rotated after passing through the through hole, so that the limiting part and the limiting protrusion are staggered at a certain angle, thereby ensuring that the crank will not fall out when it is rotated at the required angle.

[0012] The base includes a front side and a back side of the base, the back side of the base has a base recessed area, the base recessed area has a hollow boss arranged around the periphery of the motor connecting column accommodating portion, and the hollow boss is provided with an opening for the limiting protrusion of the crank to pass through.

[0013] The hollow boss arranged around the periphery of the motor connection column receiving portion can further limit the corresponding position of the crank in radial direction, thereby preventing it from loosening and shaking, especially the up and down movement of the driving assembly, improving the air sweeping stability and reducing noise. Since the opening is arranged, the arrangement of the hollow boss will not affect the limiting of the crank.

[0014] A motor fixing screw column corresponding to the position of the motor ear of the motor of the driving assembly is provided on the back side of the base.

[0015] The motor can be stably fixed on the base by the motor fixing screw column.
