Detailed ways

In order to further explain the technical means and functions of the present invention for achieving the intended purpose of the present invention, the specific embodiments, structures, features and functions according to the present application will be described in detail below with reference to the accompanying drawings and preferred embodiments. . In the following description, different "an embodiment" or "an embodiment" does not necessarily mean the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments can be combined in any suitable form.

As shown in FIG. 1 to FIG. 5, a compressor 100 according to an embodiment of the present invention includes a crankshaft 1, a support structure 2, a motor, a cylinder, and an electric protection structure. The first section of the crankshaft 1 serves as the motor shaft of the motor, and the second section of the crankshaft 1 is located in the cylinder of the compressor 100. The support structure 2 is used to provide support for the end of the crankshaft 1. Here, the "end of the crankshaft 1" means one end of the stator of the crankshaft 1 that passes through the motor, that is, one end of the first section of the crankshaft 1 that is away from the second section. As shown in FIG. 2, when the compressor 100 is placed vertically, the upper end of the crankshaft 1 is the end of the crankshaft 1.

As shown in FIGS. 1 to 5, the aforementioned support structure 2 has a first through hole 21 through which the lead wire 3 of the power supply machine passes. The foregoing electrical protection structure is used to prevent electrical connection between the lead wire 3 and the support structure 2, thereby effectively removing the safety hazard of the contact between the lead wire 3 and the metal component of the support structure 2, and improving the safety and reliability of the compressor 100. .

In order to realize the function of the foregoing electric protection structure, as shown in FIGS. 1 to 5, the aforementioned electric protection structure may include the insulating member 4. The electric protection structure separates the lead wire 3 from the support structure 2 by the insulating member 4 to prevent electrical connection between the lead wire 3 and the support structure 2. Wherein, since the insulating member 4 itself has an insulating function, the lead wire 3 can be prevented from being electrically connected to the supporting structure 2 indirectly through the insulating member 4; in addition, since the insulating member 4 can also separate the lead wire 3 from the supporting structure 2, thereby eliminating The direct contact of the lead wires 3 with the support structure 2 creates the possibility of electrical connection. In summary, it is impossible to electrically connect the lead wires 3 directly or indirectly to the support structure 2 through the provided insulating members 4, thereby achieving the technical effect of preventing electrical connection between the lead wires 3 and the support structure 2.

It should be noted here that in a specific application example, the aforementioned insulating member 4 may be in the form of a plate or a block. The insulating member 4 can be made of an insulating high temperature resistant material, such as a polytetrafluoroethylene material.

Further, the foregoing insulating member 4 may be disposed on the support structure 2, so that the technical effect of facilitating the mounting of the insulating member 4 is provided, and the structure of other components of the compressor is not damaged.

Further, as shown in FIG. 1 and FIG. 7, the foregoing insulating member 4 may be provided with a limiting hole 41 through which the lead wire 3 passes. The insulating member 4 limits the lead wire 3 through the limiting hole 41 to prevent electrical connection between the lead wire 3 and the support structure 2. In the present example, the structure in which the upper limit hole 41 of the insulating member 4 is limited is relatively simple, and the processing cost is low.

Further, the aforementioned limiting hole 41 may be opposite to the first through hole 21 on the support structure 2, and the limiting hole 41 is located on the downstream side of the first through hole 21 in the direction in which the lead line 3 is drawn. The projection of the limiting hole 41 along the axial direction of the crankshaft 1 is located in the first through hole 21, so that the limiting hole 41 can control the direction of the upstream side lead wire 3, and prevent the lead wire 3 on the upstream side of the limiting hole 41 from The first via hole 21 of the support structure 2 is in contact, that is, the lead wire 3 can be prevented from coming into contact with the support structure 2 to make an electrical connection, so that a sufficient safety distance is maintained between the lead wire 3 and the support structure 2.

It should be noted here that the above-mentioned lead wire 3 is drawn from the motor of the compressor 100 toward the upper cover of the compressor. As seen in Fig. 2, the lead line 3 is drawn from the bottom to the top. As seen in Figure 4, the lead line 3 is drawn from left to right.

Since the temperature of the casing of the compressor 100 is relatively high during operation, in order to prevent the insulating member 4 from being thermally deformed, it is preferable that the minimum distance between the aforementioned insulating member 4 and the casing of the compressor 100 is 2 mm or more.

Further, the aperture of the limiting hole 41 may be 10 mm to 20 mm, so that the aperture of the limiting hole 41 is not too small, so that the lead wire 3 is difficult to pass through, and the aperture of the limiting hole 41 is not too large. Affects the limit effect on the lead line 3. Preferably, the aperture of the limiting hole 41 is 15 mm.

Further, as shown in FIGS. 1 to 6, the aforementioned support structure 2 may include a support ring 201 and a bracket 202. The support ring 201 is disposed on a casing of the compressor 100, such as welding or the like. The bracket 202 is disposed on the support ring 201. A shaft hole 2021 for supporting the end of the crankshaft 1 is provided on the bracket 202. The end of the aforementioned crankshaft 1 can be directly inserted into the shaft hole 2021, and the bracket 202 is supported by the shaft hole 2021. Of course, a bearing can also be mounted in the shaft hole 2021 such that the end of the crankshaft 1 is inserted into the bearing, and the bracket 202 supports it through the bearing.

As shown in Fig. 1, the aforementioned bracket 202 has two or more projecting arms spaced apart in the circumferential direction. Wherein, a groove 2022 is formed between two adjacent protruding walls. The groove 2022 cooperates with the inner wall of the support ring 201 to form the aforementioned first through hole 21. It should be noted here that the axial direction of both the support ring 201 and the bracket 202 coincides with the axial direction of the crankshaft 1. In the present example, by dividing the support structure 2 into two parts of the support ring 201 and the bracket 202, there is a technical effect of facilitating processing. As seen in Figure 1, the bracket 202 has three projecting arms that are formed with three recesses 2022 in the bracket 202. Therein, each of the projecting arms can be connected to the support ring 201 by screws.

Further, as shown in FIGS. 1 and 6, in the example in which the foregoing electric shield structure includes the insulating member 4, one end of the insulating member 4 is coupled to the bracket 202 and forms a cantilever beam structure. In the present example, since the insulating member 4 forms a cantilever beam structure, it is only necessary to fix one end of the insulating member 4, thereby facilitating the mounting of the insulating member 4 and improving the mounting efficiency of the insulating member 4.

Further, as shown in FIGS. 1 and 6, one end of the aforementioned insulating member 4 is fixed to the bracket 202 by the first locking member 5. The first locking member 5 can be a screw or a bolt or the like so that the insulating member 4 can be detached from the bracket 202 for convenient maintenance or replacement.

In order to prevent the amount of deformation of the insulating member 4 after the force is too large, it is preferable that the gasket 7 be disposed between the first locking member 5 and the insulating member 4, so that when the first locking member 5 is locked, the locking force is Acting on the spacer 7, the insulating member 4 is only slightly deformed, and the service life of the insulating member 4 can be improved on the basis of the locking insulating member 4.

Further, when the first locking member 5 needs to be locked and locked by the insulating member 4, the insulating member 4 is provided with a second through hole 43 through which the first locking member 5 passes. The aforementioned spacer 7 is a T-shaped spacer 7. The stud 71 of the T-shaped spacer 7 is sleeved in the second through hole 43 to provide omnidirectional protection to the insulating member 4, and the amount of deformation of the insulating member 4 is prevented from being excessively large. Here, the stud 71 of the T-shaped spacer 7 refers to a portion of the T-shaped spacer 7 that protrudes from the annular base.

Further, the length of the stud 71 of the T-shaped spacer 7 is smaller than the length of the second via 43 by 0.05 mm to 0.5 mm. Wherein, if the stud 71 of the T-shaped spacer 7 is too long, the insulating member 4 cannot be locked; if the height difference between the stud 71 and the second via 43 of the T-shaped spacer 7 or the T-shaped spacer 7 is not too large Large, since the insulating member 4 is relatively soft, the first locking member 5 such as a screw may be pressed into the insulating member 4 too much to affect the service life of the insulating member 4.

Wherein, when the locking column 71 of the T-shaped spacer 7 contacts the bracket 202, the first locking member 5 such as a screw is stopped, when the locking post 71 of the T-shaped spacer 7 is smaller than the second through hole 43 The length of the T-pad 7 will be pressed into the insulating member 4 to a certain thickness, so as to ensure that the insulating member 4 can be locked and the amount of micro-deformation of the insulating member 4 is within an acceptable range.

Further, the inner diameter of the second via 43 is larger than the outer diameter of the stud 71 of the T-shaped spacer 7 by 0.05 mm to 0.3 mm to facilitate the insertion of the stud 71 of the T-shaped spacer 7 into the second via 43. Inside.

Further, as shown in FIG. 1 and FIG. 6, the foregoing bracket 202 and the support ring 201 can be fixed by the second locking member 6, which can be a screw or a bolt or the like. One end of the insulating member 4 may be provided with a avoiding hole 42 for avoiding the second locking member 6 to facilitate the locking of the bracket 202 and the support ring 201 by the second locking member 6 via the avoiding hole 42. Together, thus, the installation of the insulating member 4 does not affect the normal assembly of both the bracket 202 and the support ring 201.

Further, as shown in FIG. 1 , the region of the support structure 2 near the root of the lead wire 3 may be provided with a avoidance structure 8 to avoid the lead wire 3 to further prevent the support structure 2 from being electrically connected to the lead wire 3 . Technical effects. It should be noted here that "close" in this example means relative to other areas on the support structure 2. That is, the avoidance structure 8 is provided in a region of each of the regions on the support structure 2 that is closest to the root of the lead wire 3. Further, the root of the aforementioned lead wire 3 is a portion of the lead wire 3 that faces the inner wall of the support ring 201.

Further, as shown in FIG. 1, in the example in which the support structure 2 includes the support ring 201 and the bracket 202, the aforementioned support ring 201 is adjacent to the root of the lead wire 3 with respect to the bracket 202. The aforementioned avoidance structure 8 is provided on the support ring 201 to avoid the lead wire 3. The portion of the lead wire 3 passing through the support structure 2 may be referred to as a first segment. In this example, the avoidance structure 8 on the support ring 201 can cooperate with the limiting hole 41 on the insulating member 4 to limit the upper portion of the first segment and avoid the lower portion of the first segment, thereby enabling A sufficient safety distance is maintained between the entire lead wire 3 and the support structure 2 to prevent the lead wire 3 from coming into contact with the support structure 2 to cause electrical connection.

Further, the foregoing avoidance structure 8 may include a notch disposed on the support ring 201 to avoid the lead wire 3 through the notch. Among them, the structure of the notch is relatively simple, and the processing is convenient.

It should be noted here that the above-mentioned notch can adopt various structural forms as long as the technical effect of avoiding the lead wire 3 can be ensured. The structure of the notch will be specifically described below by way of example. In the first example, as shown in FIG. 8 , the aforementioned gap may be the first avoidance slot 2011 . The first avoidance groove 2011 is provided on the inner wall of the support ring 201 and penetrates both ends of the support ring 201 in the axial direction. In the second example, as shown in FIG. 9, the aforementioned notch may be the fracture 2012 so that the support ring 201 is broken in the circumferential direction to achieve the maximum avoidance effect. In the third example, as shown in FIG. 10, the front notch may be the second avoidance groove 2013, and the second avoidance groove 2013 is disposed at one end of the axial end of the support ring 201 near the root of the lead wire 3. . The second avoidance groove 2013 penetrates the opposite wall faces of the support ring 201 from the inside to the outside in the radial direction of the support ring 201, so that the technical effect of avoiding the lead wire 3 can be achieved, and the structural integrity of the support ring 201 can be maintained. To ensure the strength of the support ring 201.

Wherein, the aforementioned lead wire 3 is taken out from the motor, and sequentially passes through the support ring 201, the bracket 202 and the insulating member 4. The limiting hole 41 on the insulating member 4 can limit the direction of the upstream side lead wire 3 to prevent the lead wire 3 from coming into contact with the supporting structure 2 to cause electrical connection. However, since the support ring 201 has a certain thickness and is relatively close to the root of the lead wire 3 with respect to the bracket 202, in order to ensure a sufficient electrical safety distance between the root of the lead wire 3 and the support ring 201, the lead wire 3 passes through the support ring. A gap is opened at 201.

The compressor 100 provided by the embodiment of the present invention may be a rotary compressor. It should be understood by those skilled in the art that the rotary compressor 100 is merely an example and is not intended to limit the technical solution of the embodiment.

An embodiment of the present invention also provides an air conditioner, which may include the compressor 100 in any of the above examples.

In the above embodiment, the air conditioner provided by the present invention has the safety hazard of removing the contact between the lead wire 3 and the metal component of the support structure 2 due to the provision of the compressor 100, and improves the safety and reliability of the compressor 100. advantage.

The working principle and preferred embodiment of the present invention are described below.

The technical solution provided above limits the lead wire 3 by the insulating member 4, and ensures a sufficient safety distance between the lead wire 3 and the metal supporting structure 2.

The invention of the present application is as follows: 1. Adding an insulating member 4 to the supporting structure 2 at the end of the crankshaft 1 of the compressor 100; 2. Using the T-shaped spacer 7 to prevent the insulating member 4 from being deformed by force; 3. Guaranteeing the root portion of the motor lead-out line 3 An electrical safety distance from the support ring 201 increases the gap on the support ring 201.

As shown in FIGS. 1, 2, and 4, a motor and a compression mechanism are disposed in a sealed housing of the compressor 100. The motor includes a stator and a rotor. The compression mechanism includes a cylinder with a compression chamber, a piston disposed within the compression chamber, and a slide. The main bearing and the sub-bearing for supporting the eccentric crankshaft 1 are respectively disposed on both sides of the cylinder. The end of the crankshaft 1 is provided with a support structure 2, and in order to ensure the electrical safety of the lead wire 3 when the lead wire 3 passes through the support structure 2, an insulating member 4 made of an insulating high temperature resistant material is used.

As shown in Fig. 1, Fig. 6, and Fig. 7, the insulating member 4 is a member made of an insulating high temperature resistant material, one end of which is fixed to the support ring 201 and the bracket 202 by two screws, and the other end has a lead wire 3 for passing through. Limit hole 41. The insulating member 4 can be made of a material such as polytetrafluoroethylene.

As shown in FIGS. 1 and 6, one screw is coupled to the bracket 202 and the support ring 201, and the other screw is coupled to the T-shaped spacer 7 and the bracket 202. Since the insulating member 4 is easily deformed by force, a T-shaped spacer 7 which is 0.05 mm to 0.5 mm shorter than the insulating member 4 is added between the screw and the insulating member 4. When the screw is locked, the locking force acts on the T-shaped spacer 7, which ensures that the amount of deformation of the insulating member 4 is controllable. The inner diameter of the screw hole on the insulating member 4 should be larger than the outer diameter of the T-shaped spacer 7 by 0.05 mm to 0.3 mm to facilitate the insertion of the T-shaped spacer 7 into the screw hole. In order to prevent thermal deformation of the insulating member 4, the insulating member 4 should be greater than or equal to 2 mm from the housing. In order to ensure that the lead wire 3 can easily pass through the limiting hole 41 on the insulating member 4, the limiting hole 41 of the lead wire 3 on the insulating member 4 should have a diameter of 10 mm to 20 mm. As shown in FIG. 1, FIG. 2 and FIG. 4, the lead wire 3 is taken out through the support ring 201 and the limiting hole 41 on the insulating member 4, and then connected to the terminal or the overload, because the support ring 201 welded to the inner wall of the housing has a certain thickness and close to the root of the lead wire 3, the lead wire 3 is drawn from the enameled wire and is very close to or even in contact with the support ring 201, in order to ensure the electrical safety distance between the root of the motor lead wire 3 and the support ring 201, in the lead wire 3 A gap is made through the support ring 201. The gap of the support ring 201 is as shown in FIG. 8 to FIG. 10, and there are three kinds of notch modes. The shape of the notch is not limited to the one shown in the figure.

According to the above embodiment, the compressor 100 of the present invention and the air conditioner to which the same is applied have at least the following advantages: improving the reliability of the compressor 100.

It should be noted here that in the case of no conflict, the technical features in the above examples can be combined with each other according to the actual situation to achieve the corresponding technical effects, specifically for various combinations. One by one.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way.
