In view of this, the utility model provides a kind of compressor, reduces the friction between piston and compression chamber sidewall, to improve the combination property of compressor.The utility model additionally provides a kind of refrigerator with above-mentioned compressor.
For achieving the above object, the utility model provides following technological scheme:
A kind of compressor, comprise cylinder block, silencing cavity and the inside exhaust pipe that is connected with described silencing cavity with compression chamber and piston, wherein, described compression chamber is provided with passage in described piston stroking upward process with on the sidewall of described piston friction, described passage end is communicated with described compression chamber, the other end is communicated with silencing cavity, and described piston blocks the opening that described passage is connected with described compression chamber.
Preferably, in above-mentioned compressor, described silencing cavity comprises the first connected silencing cavity and the second silencing cavity, and described first silencing cavity is connected by gas exhaust piping with the cylinder head of compressor, described second silencing cavity is connected with inside exhaust pipe, and described passage is connected with described first silencing cavity.
Preferably, in above-mentioned compressor, described first silencing cavity is less than the distance of described second silencing cavity to described compression chamber to the distance of described compression chamber.
Preferably, in above-mentioned compressor, described in the extended distance of described passage on described compression chamber sidewall, the distance of two end faces of piston is 2-5mm.
Preferably, in above-mentioned compressor, described in the extended distance of described passage on described compression chamber sidewall, the distance of piston two end faces is 3mm.
Preferably, in above-mentioned compressor, described passage is be opened in the through hole on the described cylinder block between described compression chamber and described silencing cavity.
A kind of refrigerator, comprise compressor, wherein, described compressor is the compressor described in above-mentioned any one.
Known via above-mentioned technological scheme, compared with prior art, the utility model discloses a kind of compressor, comprise cylinder block, silencing cavity and the inside exhaust pipe that is connected with silencing cavity with compression chamber and piston, wherein, compression chamber is provided with passage in piston stroking upward process with on the sidewall of piston friction, and this passage end is communicated with the other end with compression chamber is communicated with silencing cavity, and piston blocks the opening that passage is connected with compression chamber.By above-mentioned setting, in piston stroking upward process, pressurized gas enters cylinder head, then silencing cavity is entered, and silencing cavity and compression chamber are connected with inside exhaust pipe, therefore, part gas is discharged by inside exhaust pipe, another part pressurized gas apply blowing force by passage to piston, with counteracting part even all because the inclination of crank makes piston to the frictional force of compression chamber sidewall, thus reduce the degree of wear of piston and compression chamber sidewall, reduce friction power loss, reduce and leak, improve the combination property of compressor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The plan view of Fig. 1 compressor disclosed in the utility model embodiment;
The structural representation of Fig. 2 compressor disclosed in the utility model embodiment;
The sectional view of Fig. 3 compressor disclosed in the utility model embodiment.
Embodiment
Core of the present utility model is to provide a kind of compressor, reduces the friction between piston and compression chamber sidewall, to improve the combination property of compressor.Another core of the utility model is to provide a kind of refrigerator with above-mentioned compressor.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3, the utility model discloses a kind of compressor, comprise cylinder block 1, silencing cavity 3 and the inside exhaust pipe 4 that is connected with silencing cavity 3 with compression chamber and piston 2, wherein, the sidewall that compression chamber rubs with piston 2 in row process is on the piston 2 provided with passage 5, and this passage 5 one end is communicated with the other end is communicated with silencing cavity 3 with compression chamber, and piston 2 blocks the opening that this passage 5 is connected with compression chamber all the time in running.By above-mentioned setting, in the up process of piston 2, pressurized gas enters between cylinder head 6 and cylinder block 1, then silencing cavity 3 is entered, and silencing cavity 3 and compression chamber are connected with inside exhaust pipe 4 simultaneously, therefore, part gas is discharged by inside exhaust pipe 4, another part pressurized gas apply blowing force by passage 5 pairs of pistons 2, with counteracting part even all because the inclination of crank makes the frictional force of piston 2 pairs of compression chamber sidewalls, thus reduce piston 2 and the degree of wear of compression chamber sidewall, reduce friction power loss, reduce and leak, improve the combination property of compressor.
In specific embodiment, above-mentioned silencing cavity 3 comprises the first connected silencing cavity and the second silencing cavity, and the first silencing cavity is connected by gas exhaust piping with the cylinder head 6 of compressor, and the second silencing cavity is connected with inside exhaust pipe 4, and above-mentioned passage 5 is connected with the first silencing cavity.The application can reduce the noise of gas further by arranging two silencing cavity, improve the stability of pressurized gas circulation.Passage 5 is connected with the first silencing cavity, the working pressure of the second silencing cavity can be reduced, avoid unnecessary waste.
In further embodiment, the distance of the first silencing cavity to compression chamber is set to be less than the distance of the second silencing cavity to compression chamber, to reduce the length of passage 5, reduces cost of production further.
The loss causing exhaust pressure in compression chamber or housing is flow in order to reduce pressurized gas, therefore, the top dead center of compression process end of a period is run to regardless of piston 2, still the lower dead center that breathing process is ended is run to, the opening of this passage 5 on compression chamber is blocked by the side of piston 2 all the time, thus avoids in the inflow compression chamber of pressurized gas rapid, high volume.Further, ensure that the distance of extended distance piston 2 both ends of the surface of passage 5 on compression chamber sidewall ensures all the time in the seal length of 2-5mm, reduce pressurized gas and flow to the loss causing exhaust pressure in compression chamber or housing.
Preferably, the opening of passage 5 on compression chamber sidewall is set to 3mm to the distance of piston 2 two end faces.
On the basis of technique scheme, the passage 5 of compressor disclosed in the application is for being opened in the through hole on the cylinder block 1 between compression chamber and silencing cavity 3.The number of parts can be reduced by above-mentioned setting, reduce costs, and adopt the mode of communicating stable connection of through hole.
The invention also discloses a kind of refrigerator, it comprises compressor, and wherein, this compressor is compressor disclosed in above-described embodiment, and therefore, the refrigerator with this compressor also has above-mentioned all technique effects, and this is no longer going to repeat them.
