Description

Hermetic compressor support plate

The present invention relates to a compressor, and more particularly, a hermetic compressor for improving a structure of an outer lower end of a hermetic case in a hermetic compressor used for a refrigerant circulation system of a refrigerator to inhale and discharge a refrigerant to prevent quality deterioration. It is about a support plate.

Typically, the refrigerant circulation for the endothermic and heat dissipation in the refrigerator is made in a pipe consisting of a compressor → condenser → capillary → evaporator. At this time, the compressor is a means for converting the rotational force by the electrical energy into the mechanical energy of the reciprocating motion, the refrigerant having a low boiling point is discharged by making the state of high temperature and high pressure. The refrigerant at high temperature and high pressure loses latent heat due to cooling action by heat dissipation in the condenser, condenses, separates into liquid and gas through the dryer and capillary tube, and then the liquid refrigerant becomes low temperature and low pressure. Vaporizes, absorbing the latent heat of the surroundings.

The structure and operation of such a compressor is described using FIG. 1.

The compressor 10 has a structure in which a high pressure generator 13 is mounted on the upper side of the frame 14 inside the sealed case 11 welded up and down, and a driving means is mounted on the lower side of the frame 14. The high pressure generation unit 13 can be roughly classified into a cylinder, a piston, a valve, or the like, and is connected to a shaft 12 and a motor composed of a stator 15 and a rotor 16. The high pressure generating unit 13, the shaft 12, and the motor are integrally assembled together with the frame 14, and are mounted on the lower end of the sealed case 11 via the supporting unit 17. The suction pipe and the discharge pipe, which are the flow paths of the refrigerant, are respectively mounted on the outer surface of the sealed case 11.

For reference, the shaft 12 rotated by the motor induces an eccentric cam motion at its upper part, and the eccentric cam motion again reciprocates the piston in the cylinder through the connecting rod. Accordingly, the refrigerant introduced through the suction pipe is filled into the sealed case 11 and then introduced into the cylinder through the suction muffler, and the refrigerant compressed in the cylinder passes through the discharge muffler and then sent to the condenser through the discharge pipe.

The compressor 10 completed through such a multi-step process is mounted using the support plate 18 in the refrigerator, and the painted surface is damaged due to careless handling during transportation during the inter-process transfer and shipment of the compressor 10. There are many cases.

In addition, when long-term storage or transportation in a severe state of damage to the surface of the corrosion progresses in this part can not be commercialized, and the sealed case 11 has to be replaced, but the operation is not simple.

Accordingly, the present invention is to compensate for the above disadvantages, and provides a hermetic compressor support plate that prevents quality deterioration by improving the structure of the outer bottom of the hermetic case in the hermetic compressor used on the refrigerant circulation system of the refrigerator to suck and discharge the refrigerant. It is for that purpose.

In order to achieve the above object, the present invention provides a compressor in which a main part such as a shaft, a high pressure generating part, a motor, and the like are assembled inside a sealed case, and are mounted by a support plate 18 at an outer lower end of the sealed case: The lower end of the provides a hermetic compressor support plate, characterized in that the protrusion (18a) protruding by pressing to a predetermined height (H) is formed in a quantity that can ensure a stable support during transportation of the compressor.

On the other hand, as a modification, the protrusions 18a may be formed by joining metal pieces of a material having good rust resistance and weldability instead of being stamped.

EXAMPLE

Hereinafter, with reference to the accompanying Figure 2 will be described in detail a preferred embodiment according to the present invention.

Figure 2a is a plan view of the support plate according to the present invention, Figure 2b is a cross-sectional view of the A-A portion of Figure 2a. Reference numerals not cited refer to the accompanying FIG. 1.

In the present invention, as shown in FIG. 1, main parts such as the shaft 12, the high pressure generating unit 13, and the motor are assembled into the sealed case 11, and the support plate 18 on the outer lower end of the sealed case 11 is provided. Applies to the compressor (10) mounted by.

At this time, according to the present invention, the lower end of the support plate 18 is formed in a quantity that can ensure a stable support when the compressor (18a) protruding by pressing to a predetermined height (H).

Since the support plate 18 is a structure, a steel sheet (for example, a hot rolled steel sheet) having a thickness of 2 to 3 mm is generally used, and the bending strength may be compensated by forming a bead over a predetermined length. The protrusion 18a is pressurized so that the height H protrudes about 3 to 5 mm using a punch having a tip diameter of about 2 to 3 mm. Such protrusions 18a should be formed at the bottom end of the support plate 18 to protect the coating state of other parts during the movement of the compressor. If the protrusions 18a are formed at the same time during the processing of other parts such as the above-described beads or other mounting holes, Man-hours can also be saved.

On the other hand, the numerical values presented above are merely examples and it is necessary to increase or decrease appropriately according to the material thickness of the support plate 18. It should be noted that as the support plate 18 becomes smaller in material thickness and the tip diameter of the punch, the protrusions 18a are more likely to pass through the plastic deformation zone. If the material thickness of the support plate 18 is small, it should be avoided to use the one with the small tip diameter of the punch.

Since the support plate 18 is usually mounted in two places at the bottom of the sealed case 11, the protrusions 18a are formed in two places on one support plate 18 so that the compressor 10 has the protrusions 18a in at least four places. To do that. If the protrusions 18a are large, only the number of machining is increased, and the effect is not great.

Although not shown, the protrusions 18a may be formed by joining metal pieces of a material having good rust resistance and weldability instead of being stamped.

The metal piece is cut to an appropriate size with reference to the above-described dimensions, and then fixed or welded to the bottom surface of the support plate 18. Since a material mill (for example, SUS) having good corrosion resistance and weldability is used, there is no need to paint separately. However, there is a disadvantage in that it takes a lot of labor compared to the case of FIG.

As such, when the protrusion part 18a is formed at the portion in contact with the bottom when the compressor 10 is transported, there is a side to reduce the air transport and material costs because it does not have to use a separate structure or packaging material to prevent scratching of the painted surface.

As described above, the hermetic compressor support plate of the present invention is used on a refrigerant circulation system of a refrigerator, and in the hermetic compressor that sucks and discharges the refrigerant, a protrusion is formed on the support plate of the outer lower end of the sealed case, thereby transferring and shipping the process between the compressors. According to the transportation process, there is an effect of preventing the deterioration phenomenon such as scratching, corrosion of the painted surface.

Although the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention may be variously modified and changed without departing from the spirit or the field of the present invention provided by the following utility model registration claims. It will be readily apparent to one of ordinary skill in the art that it can be used.
