Problems solved by technology

[0002] At present, most of the outdoor units of air conditioners are installed on the outer wall. The air outlet of the outdoor unit is equipped with an air outlet net cover with a grille. Due to the shielding of the grille, part of the air outlet is blocked, resulting in a decrease in the air volume of the outdoor fan. Increased power consumption of the fan motor
On the other hand, the fan of the outdoor unit is generally made of polymer materials such as AS and ABS. The outdoor unit is exposed outdoors for a long time, and the air outlet cannot be closed. Dust, etc.
After the outdoor fan is aging, when the fan is running at high speed, the fan blade part is cracked under the action of centrifugal force, which leads to the deterioration of the dynamic balance of the fan, and the vibration noise becomes louder when the outdoor unit is running

Embodiment 1

[0050] Such as Figure 2-Figure 5 As shown, the door body 2 is formed by a combination of a plurality of door panel parts 21 arranged in the circumferential direction, and the plurality of door panel parts 21 can move in directions of moving away from and approaching each other to open and close the air outlet 101 . In other words, the plurality of door panels 21 are separated from each other to open the air outlet 101 , and the plurality of door panels 21 are closed to close the air outlet 101 . The efficiency of opening and closing the air outlet 101 of the door body 2 can be shortened, which facilitates the control of the outdoor unit 100 of the air conditioner, and also makes the outdoor unit of the air conditioner more intelligent and easy to use.

[0051] For example, if the door body 2 is set in the form of splicing two door panel parts 21, the air outlet 101 can be opened by the two door panel parts 21 moving away from each other, and the air outlet 101 can be opened b...

Embodiment 2

[0055] The door body 2 is formed by a combination of a plurality of door panel parts 21 arranged in the circumferential direction, and the plurality of door panel parts 21 are movable in directions of moving away from each other and approaching each other to open and close the air outlet 101 .

[0056] Such as image 3 and Figure 4 As shown, the driving device 3 includes: a motor 31 , a driving gear 32 , a large ring gear 33 , a rack 34 and a secondary driven gear 35 .

[0057] Specifically, the driving gear 32 is coaxially connected with the output shaft of the motor 31 . The big ring gear 33 surrounds the air outlet 101 and is rotatably arranged on the outdoor machine body 1 , and the big ring gear 33 meshes with the driving gear 32 . The racks 34 are a plurality of one-to-one correspondence with the plurality of door panels 21 , each rack 34 is fixedly connected to the corresponding door panel 21 , and each rack 34 is along a direction perpendicular to the centerline of ...

Embodiment 3

[0061] Different from the previous examples, as Figure 5 , Figure 8 and Figure 9 As shown, a sliding groove 201 is formed on the surface of each door panel portion 21, and a plurality of guide rails 12 corresponding to the plurality of sliding grooves 201 are provided on the outdoor unit body 1, and the guide rails 12 are matched in the corresponding sliding grooves 201. , used to make the door panel 21 slide along the corresponding guide rail 12 to open or close the air outlet 101 . By providing a structure in which the slide groove 201 cooperates with the guide rail 12 , the purpose of the stable movement of the door panel part 21 can be realized, and the stability of the outdoor unit 100 of the air conditioner can be improved.

[0062] In addition, the section of the chute 201 is in the shape of a "T" with a large internal dimension and a small opening, and the section of the guide rail 12 is in a "T" shape with a large free end and a small fixed end, so that the guide...

Abstract

The invention discloses an outdoor unit of an air conditioner and a control method of the outdoor unit. The outdoor unit of the air conditioner comprises an outdoor unit body, a door body and a driving device; a blower is arranged in the outdoor unit body, and an air outlet which is hollow is formed in the air outlet side of the blower; the door body is movably arranged on the outdoor unit body and between the opening position where the air outlet is opened and the closing position where the air outlet is closed; the driving device is connected with the outdoor unit body and the door body and used for driving the door body to move between the opening position and the closing position. According to the outdoor unit of the air conditioner, provided by the embodiment of the invention, the air outlet is hollow, and the air outlet is closed or opened through the door body, then impurities such as water and dust, which enter the outdoor unit of the air conditioner through the air outlet, can be reduced, and good operation environment can be provided for the blower and other components, so that the service life of the outdoor unit of the air conditioner can be prolonged, and the security of the outdoor unit body can be improved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to an outdoor unit of an air conditioner and a control method for the outdoor unit of the air conditioner. Background technique [0002] At present, most of the outdoor units of air conditioners are installed on the outer wall. The air outlet of the outdoor unit is equipped with an air outlet net cover with a grille. Due to the shielding of the grille, part of the air outlet is blocked, resulting in a decrease in the air volume of the outdoor fan. The power consumption of the fan motor increases. On the other hand, the fan of the outdoor unit is generally made of polymer materials such as AS and ABS. The outdoor unit is exposed outdoors for a long time, and the air outlet cannot be closed.
