Detailed Description

The technical solutions in the embodiments of the present invention will be described below clearly and completely, and it should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present embodiment provides a housing assembly of a motor, including an inner housing 1, an outer housing 2, and a cover 3, wherein the motor is accommodated and installed in the inner housing 1, an output shaft of the motor extends out from the center of the cover 3 through the cover 3, and the outer housing 2 is provided with an installation plate 23, so that the entire housing assembly can be fixedly installed through bolts and the like.

The working environment of some motors is harsh, for example, the motor in an air conditioner often suffers from the frequent changes of cold and hot alternate impact and dry humidity, so that the content of the motor is easy to condense, and further, a series of problems of corrosion, rusting and the like are caused to the motor or a shell.

Therefore, the housing is arranged to be two layers of the inner housing 1 and the outer housing 2 in the above, the outer housing 2 is sleeved outside the inner housing 1 and is fastened and connected with the inner housing 1 through bolts, the strength is ensured, a circle of gap 12 is formed between the inner wall of the outer housing 2 and the inner wall of the inner housing 1, and hydrophilic absorbent cotton 21 is arranged in the gap 12, so that water vapor in the housing assembly can be preferentially absorbed in the absorbent cotton 21, and is prevented from being condensed on the walls of other components.

Wherein, the intercommunication has been seted up on the outer wall of inner shell 1 the inside bleeder vent of inner shell 1, so that the flow of steam, steam in the inner shell 1 is convenient for dispel the heat and hydrofuge.

When the adsorbed steam of absorption cotton 21 reachs certain degree, will reach saturated condition and no longer adsorb, because motor and casing subassembly are whole to be fixed setting, can not be at will the dismouting at work, therefore can't handle the absorption cotton 21 of saturation, and then still be provided with the roll extrusion structure in this embodiment, it is right absorption cotton 21 rolls the water absorption performance in order to extrude the condensate water, resumes absorption cotton 21.

Specifically, the rolling structure includes a cylindrical scraping roller 41, the scraping roller 41 is located in the gap 12 and is parallel to the axis of the outer shell 2 or the inner shell 1, a swing arm 42 is hinged to the rear wall of the inner shell 1, one end of the scraping roller 41 is connected to the free end of the swing arm 42, and the hinge point of the swing arm 42 and the inner shell 1 is located on the axis of the inner shell 1, so that when the swing arm 42 swings, the scraping roller 41 is driven to swing along the circumferential direction of the inner shell 1, so that the scraping roller 41 can roll against the surface of the absorbent cotton 21 to extrude out condensed water in the absorbent cotton 21.

Wherein, the quantity that adsorbs cotton 21 is two, and sets up respectively in the horizontal direction on the both sides inner wall of shell 2, and then scrape roller 41 and drive scrape the quantity of the swing arm 42 of roller 41 action and also be relative two that set up, through driving scrape roller 41 from top to bottom right adsorb cotton 21 rolls to extrude the condensate water downwards, accord with the flow direction of water, avoid the condensate water to contact too much other parts.

When the swing arms 42 are two opposite, how to control the motion of the swing arms 42 is how to control the two swing arms 42 to open and close relatively, in this embodiment, a telescopic member 44 is fixedly mounted on the housing 2, including but not limited to a cylinder, an oil cylinder, an electric push rod, and the like, the telescopic end of the telescopic member 44 is further connected with a connecting member 43, the connecting member 43 is sleeved on the swing arms 42 and can slide relative to the swing arms 42, and the telescopic direction of the telescopic member 44 is arranged on the angular bisector of the two swing arms 42, so that when the telescopic member 44 performs telescopic motion, the connecting member 43 can drive the two swing arms 42 to perform relative opening and closing swing motion to drive the scraping roller 41 to move.

What needs to be supplemented is that, for the circulation of air be convenient for heat dissipation and drainage, still set up on the outer wall of shell 2 communicate in ventilative bars 22 of clearance 12, and at least one ventilative bar 22 is located the bottom of shell 2 to make follow the comdenstion water that extrudes on the absorbent cotton 21 can downwards pass through ventilative bars 22 are discharged, avoid the interior ponding of shell 2.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
