Embodiments of the present invention will now be described with reference to the drawings. Example 1. 1 is an enlarged cross-sectional view of a main part of a scroll compressor according to a first embodiment of the present invention, FIG. 2 (a) is a plan view of a first baffle plate, and FIG. 2 (b) is a first baffle plate A-. FIG. 9 is a cross-sectional view taken along the line A, and in these drawings, the same components as those of the scroll compressor of FIG. 8 according to the conventional example are denoted by the same reference numerals, and overlapping description will be omitted.

In the scroll compressor according to this embodiment, the first baffle plate 100 is provided in the muffler chamber 14. As shown in FIG. 2, the first baffle plate 100 has bolt holes 1
00a, and a baffle plate main body 100c extending from the fixed portion 100b. As shown in FIG. 1, the baffle plate main body 100c is a surface 12a orthogonal to the shell cylinder center of the lid body 12. Is fixed to the surface 1a of the fixed scroll 1 on the muffler chamber 14 side by a bolt 101 inserted into the bolt hole 100a.

Therefore, the compressed refrigerant gas discharged from the discharge port 2 collides with the first baffle plate 100 and is guided toward the inner surface of the peripheral wall of the muffler chamber 14, so that the high pressure compressed refrigerant gas is covered. 12 does not directly collide with the surface 12a orthogonal to the shell cylinder center, and the pulsation of the compressed refrigerant gas prevents the surface 12a orthogonal to the shell cylinder center from vibrating in the shell cylinder center direction. Noise can also be reduced. Incidentally, since the peripheral wall of the muffler chamber 14 and the fixed scroll 1 have relatively high rigidity, there is a problem even if the compressed refrigerant gas collides or the pulsation of the compressed refrigerant gas is transmitted through the first baffle plate 100. There is no such vibration.

Further, the first baffle plate 100 is attached to the bolt 10
By attaching the fixed scroll 1 to the fixed scroll 1 in advance, it is possible to form a sub-assembly, thereby reducing the labor required for the assembling work.

The shape of the first baffle plate 100 is not limited to that of this embodiment, and the first baffle plate 100 extends between the discharge port 2 and the surface 12a of the lid 12 which is orthogonal to the shell cylinder center. If so, the shape is arbitrary.

Example 2. FIG. 3 is an enlarged cross-sectional view of a main part of a scroll compressor according to a second embodiment of the present invention, and FIG.
4B is a plan view of the baffle plate of FIG.

Since it is discharged to the two chambers 14b and further discharged to the outside of the compressor through the discharge pipe 15, the high-pressure compressed refrigerant gas does not directly collide with the surface 12a of the lid 12 that is orthogonal to the shell cylinder center. The pulsation of the refrigerant gas prevents the surface 12a orthogonal to the shell cylinder center from vibrating in the shell cylinder center direction, and noise caused by the vibration can be reduced.

Further, by attaching the second baffle plate 100 to the lid body 12 in advance by spot welding, press fitting, or the like, it is possible to form a sub assembly, thereby reducing the labor required for the assembling work. .

The shape of the second baffle plate 102 is not limited to this embodiment, and the number of the through holes 102a and the positions where they are formed are arbitrary. However, it is desirable to form the baffle plate main body 102b as close to the peripheral edge as possible. Further, the second baffle plate 102 does not necessarily have to divide the muffler chamber 14 in the vertical direction, and is provided so as to extend between the discharge port 2 and the surface 12 a orthogonal to the shell cylinder center of the lid body 12. The shape is arbitrary as long as it is provided, and for example, both ends of the baffle plate having a rectangular shape in plan view in the longitudinal direction may be fixed to the inner surface of the peripheral wall of the muffler chamber 14.

Example 3. FIG. 5 is an enlarged cross-sectional view of a main part of a scroll compressor according to a third embodiment of the present invention.

In the scroll compressor according to this embodiment, the second bending tube 107 is provided inside the muffler chamber 14. The second curved pipe 107 has a flange portion 107b formed at one end of a curved pipe main body 107a curved in a substantially L shape, and a second discharge opening 107c formed at the other end. The muffler chamber 14 of the fixed scroll 1 is connected by using the flange portion 107b and the bolt 104 in a state where one end is connected to the discharge port 2 and the second discharge opening 107c at the other end is directed to the inner surface of the peripheral wall of the muffler chamber 14. It is fixed to the side surface 1a. Further, a bimetal type thermostat (an example of temperature detecting means) 108 is provided on the outer peripheral surface of the peripheral wall of the muffler chamber 14 at the directing position by the second discharge opening 107c. Further, a protection circuit (not shown) is provided to perform control such as stopping the compressor when the contact of the thermostat 108 is turned on.

With this structure, the discharge port 2
The compressed refrigerant gas discharged from the inside passes through the inside of the second curved pipe 107, and is discharged toward the inner surface of the peripheral wall of the muffler chamber 14 from the second discharge opening 107c. Therefore, the high-pressure compressed refrigerant gas does not directly collide with the surface 12a of the lid body 12 orthogonal to the shell cylinder center, and the pulsation of the compressed refrigerant gas causes the surface 12a orthogonal to the shell cylinder center to vibrate in the shell cylinder center direction. It is also possible to reduce noise caused by vibration.

Further, the compressed refrigerant gas blown onto the inner surface of the peripheral wall of the muffler chamber 14 raises the temperature of the peripheral wall of the muffler chamber 14 at that portion until it becomes substantially the same as the temperature of the compressed refrigerant gas, so that the compressed refrigerant gas temperature becomes an abnormally high temperature. In that case, the contact of the thermostat 108 will be turned on and the compressor will be stopped. With a simple structure, the abnormal high temperature state of the compressed refrigerant gas can be detected promptly,
It is possible to protect the compressor.

Further, the second bending tube 107 is connected to the bolt 10
By attaching the fixed scroll 1 to the fixed scroll 1 in advance by means of 4, it is possible to form a sub-assembly, thereby reducing the labor required for the assembling work.

In this embodiment, as shown in FIG.
The discharge opening 107c of the second discharge opening 107c is directed toward the inner peripheral surface of the lid body 12 near the connection portion 12b with the shell body 9. However, the directivity position of the second discharge opening 107c is limited to this embodiment. Instead, for example, a portion 9a near the frame 4 of the shell body 9 or a portion 12c near the upper end of the peripheral wall of the lid body 12
For example, any point having high rigidity may be directed. Further, the temperature detecting means is not limited to the thermostat, and for example, an electronic temperature sensor may be used.

Further, in addition to the structure of this embodiment, the second discharge opening 10 of the second bending tube 107 is also provided, as in the fourth embodiment.
By attaching an oil separating means to 7c and forming an oil return hole in the fixed scroll 1 for communicating the low pressure chamber 13 and the muffler chamber 14, in addition to the effect of this embodiment, the same effect as that of the fourth embodiment can be obtained. It is also possible to play.
