Problems solved by technology

[0003] Large-scale water-cooled units include household water machines and modular water machines. There are heating devices inside the outdoor electric control box. In winter, snakes and other animals like to hide in the box. The plastic-sealed motor of the air conditioner is also very easy to attract a large number of ants to crawl in, resulting in The motor is damaged, and after the air conditioning unit is used for a long time, a large amount of dust will enter the electric control box, resulting in a decrease in insulation performance, and in severe cases, it will cause the unit to fail
Have a certain impact on the quality of the air conditioner

Embodiment 1

[0040] figure 1 For the schematic diagram of the cable hole sealing structure 1, please refer to figure 1 shown.

[0041] The wire hole sealing structure 1 is applied in the air conditioner, and the wire hole 3 in the air conditioner is sealed to prevent snakes, ants and other animals from climbing into the unit, and at the same time, it also improves the gap for a large amount of dust to pass through the wire hole 3 into the unit to improve the safety and service life of the unit.

[0042] Specifically, the housing 2 is provided with a wire-passing hole 3, and the wire 4 passes through the wire-passing hole 3, and is connected with the circuit board or the electric control component 5 in the housing 2. Since the wire 4 and the wire-passing hole 3 There is a certain gap between them, the gap is larger at some positions of the air conditioner, and the gap is smaller at some positions. In short, there will be a gap between the wire hole 3 and the wire 4.

[0043] For example:...

Embodiment 2

[0061] Embodiment 2 of the present invention provides an electric control box structure, which includes an electric control box body, an electric control component 5 and the cable hole sealing structure 1 provided in Embodiment 1.

[0062] The wire hole sealing structure 1 includes a housing 2, a wire 4, a hot-melt adhesive filling body 6 and a fixing sleeve 7. In this embodiment, the electric control box is the above-mentioned housing 2, and a wire passage is provided on the electric control box. The hole 3 and the electric control component 5 are arranged inside the electric control box, and the wire 4 passes through the wire hole 3 and is electrically connected with the electric control component 5 .

[0063] The gap between the wire 4 and the wire-passing hole 3 is sealed by the hot-melt adhesive filler 6, which effectively prevents snakes, insects and other animals from climbing into the electric control box through the wire-passing hole 3, and improves the safety performa...

Embodiment 3

[0065] Embodiment 3 of the present invention provides an air conditioner plastic-encapsulated motor, including a motor housing, a circuit board, and the cable hole sealing structure 1 provided in Embodiment 1. The specific description is as follows:

[0066] The wire hole sealing structure 1 includes the housing 2, the lead wire, the hot melt adhesive filler 6 and the fixing sleeve 7. The motor housing is the housing 2 in the wire hole sealing structure 1. The motor housing is provided with a The wire hole 3, the circuit board is arranged in the motor casing, and the lead wires pass through the wire hole 3 and are electrically connected to the circuit board.

[0067] The gap between the lead-out line and the wire-passing hole 3 is sealed by the hot-melt adhesive filler 6, which can effectively prevent ants and the like from climbing into the motor through the wire-passing hole 3, improve the safety of the motor, and make the motor not easy to be damaged by a large number of ant...

Abstract

The invention discloses a wire passing hole seal structure and method and an air conditioner, and relates to the technical field of air conditioners. The wire passing hole seal structure comprises a hot melt adhesive filling body and a shell with a wire passing hole. The wire passing hole of the shell is filled with the hot melt adhesive filling body. The wire passing hole seal method comprises the steps that in the penetration step, a to-be-penetrated wire provided with the hot melt adhesive filling body is clamped in the wire passing hole; and in the seal step, the hot melt adhesive fillingbody at the position of the wire passing hole is heated and is expanded and melted, and a gap between the to-be-penetrated wire and the wire passing hole is sealed. The wire passing hole seal structure is reasonable in design, ingenious and simple in concept, high in practicability, convenient to operate, and capable of sealing the wire passing hole in the air conditioner, and accordingly the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a sealing structure, a sealing method and an air conditioner for a wire hole. Background technique [0002] Central air conditioners are divided into two types: air-cooled units and water-cooled units. The fan refers to the direct exchange of fresh air for cooling or heating. The water machine refers to cooling or heating the heat medium water and sending it to the fan coil air-conditioning system. The cold energy is sent to the designated lot. [0003] Large-scale water-cooled units include household water machines and modular water machines. There are heating devices inside the outdoor electric control box. In winter, snakes and other animals like to hide in the box. The plastic-sealed motor of the air conditioner is also very easy to attract a large number of ants to crawl in, resulting in The motor is damaged, and after long-term use of the air conditioning unit, a ...
