Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air duct assembly and an air conditioner. Background Art

[0002] The motion mechanisms of air conditioners are typically driven by motors. To ensure motor reliability, these motors must be sealed to prevent air and water ingress. Traditional motor sealing systems typically involve attaching a sealing cover to the motor, leaving a wiring hole in the cover for the motor wiring. The motor wiring is then wrapped with a strip of sponge, which is then placed over the wiring hole for sealing.

[0003] While the above sealing methods appear simple and reliable, their reliability is significantly reduced if the sealing structure is located near or within the air duct. During cooling, cold air constantly blows against the sealing cover, causing the entire cover to gradually cool. Furthermore, if the motor is operating, the rotation of the motor generates heat, which can cause condensation inside the sealing cover, potentially leading to water intrusion into the motor. Summary of the Invention

[0032] See also Figures 1 to 12 As shown, according to an embodiment of the present application, the air duct assembly includes a chassis 1 and an air duct, a motor base 2 for mounting a motor is provided in the chassis 1, the side wall of the motor base 2 and the air duct wall of the air duct are isolated by an isolation structure, and an isolation cavity is formed between the isolation structure and the air duct wall to isolate the heat transfer path between the air duct and the motor base 2.

[0033] The air duct assembly is designed to isolate the cavity where the motor 14 is located from the air duct through an isolation structure, so that the motor installation cavity and the air duct do not affect each other. A partition cavity that blocks the heat propagation path is formed between the isolation structure and the air duct wall, preventing the heat of the air flow in the air duct from affecting the cavity where the motor is located. The motor and the air duct are isolated from each other, and water and air are not allowed to enter the motor, thereby ensuring the electrical safety of the motor.

[0034] The partition cavity can be an air cavity or filled with thermal insulation material, so that it can effectively isolate the cold and heat sources, prevent the spread of energy, avoid the air energy in the air duct from being transferred to the motor installation cavity and causing adverse effects on the motor installation cavity, and effectively protect the safe operation of the motor.

[0035] The isolation structure includes a partition wall 3 disposed between the sidewall of the motor base 2 and the air duct wall. The partition wall 3 extends from the bottom of the motor base 2 to the wall surface of the air duct wall. The partition wall 3 is an annular partition wall that is sleeved on the outside of the motor base 2. It can form a more comprehensive isolation zone between the motor base 2 and the air duct wall, hindering the energy transferred by the airflow in the air duct and preventing the airflow energy in the air duct from being transferred to the motor mounting cavity of the motor base 2.

[0036] The duct wall includes an insulating section 4 and a matching section 5. The matching section 5 extends from the bottom of the insulating section 4 to the chassis 1. The insulating section 4 is provided with insulating material. The partition wall 3 extends to the bottom of the insulating section 4. The insulating section 4 includes an outer wall and foam provided on the inner side of the outer wall. The foam can be used to insulate the airflow in the duct, prevent the airflow energy from leaking out, and improve the energy utilization rate of the airflow in the duct. The partition wall 3 extends to the bottom of the insulating section 4, which can form a better isolation for the cavity between the duct wall and the partition wall 3, and more effectively prevent the airflow energy in the duct from entering the motor base 2 through the gap between the partition wall 3 and the duct wall, thereby affecting the air temperature in the motor base 2.

[0037] In one embodiment, a partition cavity is formed between the mating section 5, the partition wall 3 and the bottom wall of the chassis 1, and the minimum spacing between the partition wall 3 and the mating section 5 is not less than 4 mm, thereby ensuring that there is sufficient spacing between the partition wall 3 and the structure of the air duct wall where no foam is set, effectively isolating the airflow energy transfer.

[0038] In one embodiment, a thermal insulation layer is provided on the side of the mating section 5 facing away from the air duct. This thermal insulation layer can be used to form a thermal insulation structure for the air duct wall structure that is not provided with foam, thereby more effectively preventing airflow energy transmission between the air duct and the motor base 2. The thermal insulation layer can be, for example, sponge, which can be attached to the surface of the air duct wall facing the partition wall 3.

[0039] The outer peripheral wall of the partition wall 3, which faces the air duct, is provided with a lateral extension section 8 extending toward the air duct. A stopper structure is formed between the side of the lateral extension section 8 facing away from the partition wall 3 and the mating section 5. In this embodiment, the provision of the lateral extension section 8 allows the air duct structure to be split and designed, reducing its complexity while also facilitating the mating between the chassis 1 and the air duct wall. To improve the seal between the motor mounting cavity of the motor base 2 and the air duct and prevent air leakage in the air duct, a stopper structure is used to mate with the lateral extension section 8.

[0040] The lateral extension section 8 in this embodiment includes a lateral protrusion and a stopper. The lateral protrusion is connected to the outer peripheral wall of the partition wall 3 on the side facing the air duct wall, and is used to increase the distance between the partition wall and the air duct wall, thereby increasing the volume of the air cavity between the partition wall 3 and the air duct wall and enhancing the thermal insulation performance between the partition wall 3 and the air duct wall. The stopper is used to cooperate with the mating section 5 at the end of the air duct wall to form a stopper structure, thereby improving the sealing effect between the partition wall 3 and the air duct wall.

[0041] In one embodiment, a first partition cavity 6 is formed between the mating section 5, the partition wall 3 and the lateral extension section 8. The partition cavity includes the first partition cavity 6. The minimum gap of the first partition cavity 6 is not less than 4 mm, thereby ensuring that there is sufficient spacing between the partition wall 3 and the structure of the air duct wall where no foam is set, effectively isolating the airflow energy transfer.

[0042] The side of the lateral extension section 8 away from the partition wall 3 is connected to a guide wall 9. The guide wall 9 is connected to the matching section 5 and extends to the bottom wall of the chassis 1 in a direction away from the partition wall 3. As part of the air duct, it guides the airflow. In this embodiment, the air duct structure is divided into two parts. One part is used as a part of the air duct component to form the upper air duct, and the other part is formed as a part of the chassis 1 on the chassis 1 as the guide wall 9, which serves as the lower air duct and cooperates with the upper air duct to form a complete air duct structure. The lateral extension section 8 serves as a transitional matching structure between the lower air duct and the upper air duct at the matching position, forming an integrated structure with the guide wall 9, and forming a stop structure at the end position of the air duct wall to achieve a sealed fit between the chassis 1 and the air duct component.

[0043] A second partition cavity 7 is formed between the partition wall 3, the lateral extension 8, the guide wall 9, and the bottom wall of the chassis 1. The partition cavity includes the second partition cavity 7, and the minimum gap of the second partition cavity 7 is not less than 10 mm. In this embodiment, the minimum gap of the second partition cavity 7 is 12 mm or greater, thereby increasing the distance between the motor base 2 and the air duct wall, making the air cavity therebetween sufficiently large to effectively prevent the spread of cold air in the air duct.

[0044] A drive assembly 10 is also disposed within the motor base 2. A gear cover 11 is provided at the opening of the motor base 2, and the gear cover 11 is sealed to the sidewall of the motor base 2. The drive assembly 10 includes a motor 14, a pinion, and a gear. The motor is positioned using diagonal locating pins and then fixed to the motor base 2 via diagonal fixings. The locating hole on the pinion fits into the motor shaft, and the locating hole on the gear fits into the gear shaft fixed to the motor base 2. The pinion and gear mesh with each other.

[0045] A stop structure is formed between the gear cover 11 and the motor base 2. The upper end of the motor base 2 forms an L-shaped stepped structure, and the lower end of the gear cover 11 forms an inverted L-shaped stepped structure. The L-shaped structure and the inverted L-shaped structure form a stop structure between the motor base 2 and the gear cover 11, thereby achieving a more effective sealing effect.

[0046] In order to prevent the gear cover 11 from warping and deforming, in this embodiment, the gear cover 11 is fixedly secured to the motor base 2 by a snap connection. A plurality of snap-in openings 13 are provided on the circumference of the motor base 2, and corresponding hooks 12 are provided on the gear cover 11. The hooks 12 snap into the snap-in openings 13, allowing the gear cover 11 to be tightly fastened to the motor base 2. This forms a sealing structure between the assembly structure of the gear cover 11 and the motor base 2, ensuring a more balanced and stable connection structure between the gear cover 11 and the motor base 2 and ensuring an assembly clearance between the motor base 2 and the gear cover 11.

[0047] In this embodiment, the motor wires are opened from the bottom of the chassis 1 so that the motor wires are routed from the bottom, thereby preventing the front of the gear cover 11 from being opened and destroying the sealing performance between the gear cover 11 and the motor base 2.

[0048] By adopting the above-mentioned scheme of the present application, a stopper structure can be used to seal between the chassis 1 and the air duct wall, thereby achieving a seal between the chassis 1 and the air duct wall, forming a first layer of protection; an annular isolation wall is provided between the air duct wall and the motor base 2 of the chassis 1, and an air cavity is formed between the annular isolation wall and the air duct wall, and the air cavity is used to isolate the cold transfer between the air duct and the motor base 2, forming a second layer of protection; a stopper assembly is formed at the matching position between the motor base 2 and the gear cover 11, so that the motor base 2 and the gear cover 11 cooperate to form a sealed motor installation cavity, preventing external air from entering the motor installation cavity, forming a third layer of protection. Through the above-mentioned design, the motor can be effectively prevented from entering wind and water, thereby ensuring the electrical safety of the motor.
