Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The housing structure 300, the compressor 200, and the electric appliance according to some embodiments of the present invention will be described with reference to fig. 1 to 9.

Example 1:

as shown in fig. 1 and 3, an embodiment of the present invention provides a shell structure 300 for a compressor 200, including: a first housing 310 and a second housing 320, the second housing 320 and the first housing 310 being adhered to each other and enclosing at least a portion of a compression unit receiving chamber 400 of the compressor 200.

The compressor 200 is one of the core components of air conditioning equipment and refrigeration equipment, and is widely used in various household or commercial electrical appliances such as air conditioners, refrigerators, freezers, cooling fans, and the like. Among them, the reciprocating compressor 200 is also called a piston type compressor 200, which compresses a compression medium such as a refrigerant by a compression assembly 500 including a cylinder and a piston.

The compressor 200 includes not only the compressing assembly 500 but also a housing structure 300 covering the compressing assembly 500. The housing structure 300 functions to keep the compression assembly receiving chamber 400 of the compressor 200 sealed and to protect the compression assembly 500.

In the related art, the shell of the compressor generally includes an upper shell and a lower shell or an upper shell, a middle shell and a lower shell, and the shells are connected to each other by welding. The welding process is complicated, and therefore, the production, processing, installation and assembly efficiency of the compressor and the shell of the compressor are not ideal. In addition, in order to perform the welding process, the casing of the compressor in the related art needs to be provided with a structure such as a limit step. Such structures are usually provided at the edge of the compressor casing and serve to avoid displacement of the casing during welding. Therefore, the shell of the compressor in the related art needs to be processed with a welding matching part with a complex structure, such as a limiting step, during production, and the material cost and the labor cost are correspondingly high. In summary, one of the disadvantages of the shell of the compressor in the related art is that the shell is inconvenient to produce and manufacture, and thus the production cost and the processing efficiency are not ideal.

In order to facilitate the production and manufacture of the compressor and the housing thereof, the present embodiment employs a bonding manner to bond at least two portions of the housing structure 300 of the compressor 200 to each other. The housing structure 300 of the present embodiment may include two or more housings. In other words, the first casing 310 and the second casing 320 of the present embodiment may be an upper casing and a lower casing of the compressor, an upper casing and a middle casing of the compressor, or a lower casing and a middle casing of the compressor. The first housing 310 and the second housing 320 may be bonded to each other by an adhesive such as a super glue or a metal glue.

The present embodiment can facilitate the manufacturing of the compressor 200 and the shell structure 300 thereof by improving the connection manner between the first shell 310 and the second shell 320. Specifically, the respective portions of the housing structure 300 of the present embodiment do not require the provision and machining of a weld fitting structure such as a limit step. In addition, the shell structure 300 of the embodiment is not only simple in structure, but also convenient to install and assemble, can avoid complex welding steps, saves labor cost and improves production efficiency.

Example 2:

as shown in fig. 1 and 3, the embodiment of the present invention provides a housing structure 300, and in addition to the technical features of the above embodiment 1, the present embodiment further includes the following technical features.

At least a portion of the first housing 310 and at least a portion of the second housing 320 abut against each other so that the first housing 310 supports the second housing 320.

Specifically, in the present embodiment, the first casing 310 serves as a compressor lower casing, and the second casing 320 serves as a compressor upper casing. At least a part of the lower edge of the second housing 320 and at least a part of the upper edge of the first housing 310 are in abutting contact with each other, so that the first housing 310 supports the second housing 320. Thus, the present embodiment can facilitate the bonding operation, and improve the stability of the connection between the first and

second casings

310 and 320 after bonding, thereby improving the sealing degree and operational reliability of the compressor 200.

Example 3:

as shown in fig. 2 and 4, the embodiment of the present invention provides a housing structure 300, and in addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

At least a portion of the second housing 320 is embedded in the first housing 310 with a gap 330 between an outer periphery of the second housing 320 and an inner periphery of the first housing 310.

Specifically, the first and

second housings

310 and 320 include closed and open ends, respectively. Wherein the open end of the second casing 320 extends into the open end of the first casing 310 such that at least a portion of the second casing 320 is embedded in the first casing 310. Thus, the outer periphery of the open end of the second housing 320 is disposed opposite the inner periphery of the open end of the first housing 310, forming a gap 330 therebetween.

The purpose of the gap 330 in the present embodiment is to facilitate the injection of the adhesive between the first housing 310 and the second housing 320 to further ensure the bonding effect.

In some embodiments of the present invention, the first casing 310 serves as a lower casing of the compressor, and the second casing 320 serves as an upper casing of the compressor, so that an operator can conveniently inject the adhesive into the gap 330 between the first casing 310 and the second casing 320 from top to bottom, thereby achieving the purpose of facilitating the bonding operation.

Example 4:

The gap 330 is tapered from top to bottom.

Specifically, the present embodiment may allow the gap 330 to be formed between the first housing 310 and the second housing 320 by designing and adjusting the sizes of the first housing 310 and the second housing 320, respectively. The shape of the first housing 310 and/or the second housing 320 may also be designed and adjusted, so that the gap 330 is formed between the first housing 310 and the second housing 320 by providing a chamfer or a slot. Wherein the cross section of the gap 330 has a triangular or trapezoidal or wedge shape, for example, and the gap width of the gap 330 is gradually reduced from top to bottom.

The present embodiment can prevent the adhesive from entering the compression assembly receiving chamber 400 of the compressor 200 through between the first and

second housings

310 and 320 by properly setting the shape of the gap 330.

Example 5:

as shown in fig. 2 and 5, the embodiment of the present invention provides a housing structure 300, and in addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

The first housing 310 includes: a first flange 312, the first flange 312 extending from an edge of the first housing 310 and forming at least one stepped structure 340. Wherein at least a portion of second housing 320 is embedded in stepped structure 340 such that at least a portion of first flange 312 supports second housing 320.

In this embodiment, the first flange 312 is disposed around the edge of the open end of the first housing 310, and extends and bends outward from the edge of the open end of the first housing 310. Thus, the edges of first flange 312 and first housing 310 cooperate to define one or more stepped structures 340. In some embodiments of this embodiment, the step structure 340 is in the shape of a right-angle step. In addition, the step structure 340 may be formed as an acute step or an obtuse step. In addition, the present embodiment may form a gap 330 between first flange 312 and second housing 320 by machining and designing first flange 312.

The open end edge of the second shell 320 extends into the step structure 340 and is in abutting contact with the bottom wall and the side wall of the first flange 312. Thus, the stepped structure 340 disposed on the first housing 310 can provide a supporting and fixing function to the second housing 320. Also, the above structure allows the first and

second housings

310 and 320 to be in close contact, whereby it is possible to further prevent the adhesive from entering the compression assembly housing chamber 400 through between the first and

second housings

310 and 320.

It should be noted that the present embodiment may be formed by casting, casting or cutting so that the first flange 312 and the first housing 310 are connected to each other in an integrally formed manner.

Example 6:

First cuff 312 includes: a first bend section 314 and a second bend section 316. The first bent section 314 extends outward from the edge of the first housing 310. The second bending section 316 extends upward from an end of the first bending section 314 away from the first housing 310. The second housing 320 is in abutting contact with the first bending section 314, and the second bending section 316 surrounds at least a portion of a circumference of the second housing 320.

In this embodiment, the first bending section 314 and the second bending section 316 are integrally formed. The first bending section 314 extends outward along the radial direction of the first housing 310, and the second bending section 316 is bent and extends vertically upward from one end of the first bending section 314 away from the first housing 310. Thus, the upper surface of the first bend section 314 and the inner surface of the second bend section 316 together enclose a stepped structure 340 in which the second housing 320 is embedded.

With the structure of the present embodiment, the lower surface of the open end of the second housing 320 is in contact with the upper surface of the first bending section 314, and a gap 330 is formed between the side surface of the open end of the second housing 320 and the inner surface of the second bending section 316.

The first flange 312 including the first bending section 314 and the second bending section 316 can provide good support and fixation for the second housing 320, effectively ensure the stability of connection between the first housing 310 and the second housing 320, limit the flow of the adhesive, prevent the adhesive from entering the compression assembly accommodating cavity 400, and ensure that the adhesive is smoothly solidified at the joint of the first housing 310 and the second housing 320.

Example 7:

as shown in fig. 4, the embodiment of the present invention provides a housing structure 300, which further includes the following technical features in addition to the technical features of any one of the above embodiments.

First cuff 312 also includes: at least one chamfered structure 350, the at least one chamfered structure 350 being disposed on an inner periphery of the second bend section 316.

The at least one chamfering structure 350 of the present embodiment may be a triangular or wedge-shaped chamfering structure 350, or may be a plurality of chamfering structures 350 connected in sequence and with gradually changing angles. The chamfer structure 350 may be machined by cutting. The chamfer 350 is specifically disposed on the first housing 310 at the second bend 316 of the first flange 312.

The chamfered structure 350 is provided to form a gap 330 at the joint fitting of the first housing 310 and the second housing 320 for the injection of the adhesive.

Example 8:

as shown in fig. 7 and 8, the embodiment of the present invention provides a housing structure 300, which further includes the following technical features in addition to the technical features of any one of the above embodiments.

The second housing 320 includes: and a second flange 322, the second flange 322 extending from the edge of the second housing 320. The first flange 312 has a mating slot 360 therein, and at least a portion of the second flange 322 fits into the mating slot 360.

The second flange 322 of this embodiment is disposed around the edge of the open end of the second housing 320, and serves to enhance the stability of the connection between the second housing 320 and the first housing 310. The first flange 312 is provided with a fitting groove 360 for fitting with the second flange 322. In the coupled and mated state of the first housing 310 and the second housing 320, the second flange 322 is inserted into the mating groove 360.

The above structure of the embodiment can limit the relative movement between the first casing 310 and the second casing 320, and particularly, in the operating state of the compressor 200, the second flange 322 and the fitting groove 360, which are fitted to each other, can further ensure the sealing performance between the first casing 310 and the second casing 320 and the connection stability between the first casing 310 and the second casing 320, thereby effectively avoiding the looseness of the casing structure 300 caused by the vibration of the compressor 200. In addition, the engagement of the second flange 322 in the mating groove 360 provides a stop for the gap 330 between the first housing 310 and the second housing 320, further preventing adhesive from entering the compression assembly 500.

Example 9:

as shown in fig. 6 and 8, the embodiment of the present invention provides a housing structure 300, which further includes the following technical features in addition to the technical features of any one of the above embodiments.

The thickness of the second flange 322 increases from the end close to the second housing 320 to the end far from the second housing 320, and the shape of the fitting groove 360 is matched with the shape of the second flange 322.

For clarity, the end of second flange 322 near second shell 320 is defined as the neck end, and the end of second flange 322 far from second shell 320 is defined as the head end. The cross-sectional shape of the second flange 322 may be triangular or wedge-shaped or trapezoidal or stepped. In other words, namely: the thickness of the second flange 322 increases stepwise or gradually from the neck end to the head end. Accordingly, the slot shape and slot size of the mating slot 360 are adapted to the second flange 322 so that they can be fitted and mated. For example, the cross-sectional shape of the second flange 322 of the present embodiment is a triangle, wherein the head end of the second flange 322 is formed as the end of the triangle near the bottom edge, and the neck end of the second flange 322 is formed as the end of the triangle near the included angle between the two oblique edges. For another example, the cross-sectional shape of the second flange 322 of the present embodiment is a trapezoid, wherein the head end of the second flange 322 is formed as the end of the trapezoid near the lower bottom edge, and the neck end of the second flange 322 is formed as the end of the trapezoid near the upper bottom edge, thereby forming a structure with a thin neck end and a thick head end.

This embodiment can improve the tightness of the connection fit between the second flange 322 and the fitting groove 360, and particularly, prevent the first housing 310 and the second housing 320 from being loosened from each other due to the vibration of the compressor 200.

Example 10:

as shown in fig. 8, the embodiment of the present invention provides a housing structure 300, which further includes the following technical features in addition to the technical features of any one of the above embodiments.

The second flange 322 includes: a recess 324. The groove 324 is disposed around the edge of the second housing 320 and is depressed downward by the surface of the second flange 322.

In some embodiments of the present embodiment, the groove 324 is an annular groove disposed around the open end edge of the second housing 320, and can be formed by cutting. The bottom surface of the groove 324 may be a plane, or a spherical surface or a hemispherical surface with a certain curvature.

The recess 324 may be configured such that the thickness of the end of the second flange 322 proximate to the second housing 320 is less than the thickness of the end of the second flange 322 distal from the second housing 320. In addition, adhesive entering gap 330 may be stopped by groove 324. Thus, excess adhesive may remain at the groove 324 and set at the junction of the first housing 310 and the second housing 320. Thus, the provision of the groove 324 further prevents adhesive from entering the compression assembly 500.

Example 11:

The thickness of the second flange 322 ranges from 1 mm to 2 mm.

In some embodiments of this embodiment, the thickness of the second flange 322 is 1.5 mm. The thickness of the second flange 322 is too large to make the second housing 320 difficult to be embedded into the first housing 310, and the thickness of the second flange 322 is too small to make the connection stability between the second housing 320 and the first housing 310 lower. For this reason, this embodiment rationally sets up the thickness scope of second turn-ups 322, on the basis of guaranteeing the convenient degree of assembly, guarantees the stability of being connected of second casing 320 and first casing 310.

Example 12:

an embodiment of the present invention provides a housing structure 300, which further includes the following technical features, in addition to the technical features of any of the above embodiments.

The second housing 320 and the first housing 310 are bonded to each other by metal glue and/or super glue.

The specific type and specification of the adhesive including metal glue or super glue can be selected by those skilled in the art according to actual conditions and needs. For example, the adhesive of the present embodiment may be ethyl cyanoacrylate. The metal glue and/or the super glue have the advantages of high temperature resistance, aging resistance, long stability and the like, and can ensure the connection stability between the first shell 310 and the second shell 320.
