Fig. 6 A are effect, the schematic diagram of effect for illustrating the hermetic type compressor in present embodiment, and Fig. 6 B are to illustrate ratio
The schematic diagram of effect, effect compared with the existing hermetic type compressor in example.
It is electronic in frame the 24B compressing member of configuration up and down 20B and electric element 30B in the comparative example shown in Fig. 6 B
Element 30 is elastically supported in closed container 3B by helical spring 9B, 9B.In this case, due to the (compression of internal mechanism portion
Element 20B and electric element 30B) center of gravity be located at than helical spring 9B, 9B upper end by the top, therefore in the running to two
When the direction of arrow is vibrated, vibration angle b becomes big.
In contrast, in the present embodiment shown in Fig. 6 A, compressing member 20 is configured on the top of frame 24, in bottom
Electric element 30 is configured, frame 24 is elastically supported in closed container 3 by helical spring 9,9.In this case, during operating
Compressing member 20 vibrates to two directions of arrow respectively with electric element 30, because center of gravity is located at the height and position of frame 24 (with spiral shell
Revolve the mutually level position in upper end of spring 9,9), so angle of throw a (＜ b) diminishes.
In this way, in hermetic type compressor CMP, compressing member 20 is configured in the upside of frame 24, in the downside of frame 24
Electric element 30 is configured, is elastically supported by frame 24 by helical spring 9,9, it is possible to decrease the vibration in internal mechanism portion.And
And, by the way that the position of helical spring 9 to be configured to the outer circumferential side of cylinder body 21, it can more effectively suppress shaking for internal mechanism portion
It is dynamic.
In addition, in the present embodiment, compared with can reduce vibration compared with comparative example and angle of throw a is diminished, energy
Space CL (reference picture 4) of the internal mechanism portion (compressing member 20 and electric element 30) between closed container 3 is enough set to shorten.
As a result, closed container 3 can be made to diminish, hermetic type compressor CMP miniaturization can be sought.
In addition, setting the rubber base 10 (reference picture 4) of resilient support closed container 3 in each stage portion 3a bottom.The rubber
Rubber base 10 is supported on the metallic plate 11 on the lower house 3n for being fixed on closed container 3.In addition, rubber base 10 is configured in lead
On vertical direction (above-below direction) on the position overlapping with helical spring 9.
By being thusly-formed stage portion 3a, helical spring 9 is configured on stage portion 3a, helical spring 9 can be arranged on not
Therefore, it is possible to prevent noise that helical spring 9 is produced in lubricating oil internal vibration, it be able to can seek in the height of dip lubrication oil
Hermetic type compressor CMP tranquilization.In addition, the bottom by the way that rubber base 10 to be configured to stage portion 3a, can prevent rubber
The lower house 3n of seat 10 from closed container 3 is downwards bigly prominent, and the height that can suppress hermetic type compressor CMP is uprised, can
Seek hermetic type compressor CMP miniaturization.
But, due to configuring the weight of cylinder body 21, piston 22 etc. on compressor room side Q2, it is compared to anti-compressor room
Side Q3 (side opposite with compressor room side) weight becomes weight, and the load for acting on helical spring 9 becomes big.If in this case, making spiral
The species of spring 9 is identical and makes the height of the lower end bearing surface of helical spring 9 of both sides identical, then the compressor room side Q2 amount of sinking to
(amount of contraction) becomes many, and internal mechanism portion 20,30 is inclined state in the A-stage before operating.Additionally, it is contemplated that during operating
Vibration (inclination) between closed container 3 and internal mechanism portion installation space (surplus).But, if making the height in the face of abutting
Identical, due to there is a possibility that internal mechanical portion is collided in closed container 3, just generating significantly ensures the necessity in space
Property, compressor maximization.
Therefore, in the present embodiment, it is with the spiral winding 9 of compressor room side Q2 (side of cylinder body 21, Fig. 7 left side)
What the lower end of helical spring 9 of the height than anti-compressor room side Q3 (Fig. 4 right side) for the bearing surface 3c that lower end is abutted was abutted supports
The device that the high mode of junction 3d height is constituted.Also, as described above, all helical springs 9 are with identical (shape and spy
Property) species spring constitute.The difference of bearing surface 3c height and bearing surface 3d height is set as supporting with helical spring 9
When, interior structural component is the value of horizontality in the A-stage before operating.
In this way, in hermetic type compressor CMP, by making bearing surface 3c height of the height than bearing surface 3d high, in fortune
A-stage before turning, due to internal mechanism portion can be supported with horizontality, therefore, it is possible to suppress inside during operating smaller
The inclination of mechanism part.As a result, the space CL (reference picture 4) between confined space 3 and internal mechanism portion can be set smaller, can
Realize hermetic type compressor CMP miniaturization.
Also, the bearing surface 3c height situation different from bearing surface 3d height in the above description, is enumerated as example
Son is illustrated, but it is also possible to which it is identical height to make bearing surface 3c, 3d, below extension 24d, 24f of frame 24
Highly, height and position of the compressor room side Q2 extension 24d height and position than anti-compressor room side Q3 extension 24f
It is high.
Fig. 7 is the chart for representing [bearing internal loss] and [bearing length/diameter of axle] relation.Also, " bearing internal loss " passes through
Compressor is operated under identical operating condition to be compressed the comparison of machine input (consumption electric power) and obtain.Here identical operating
Condition refers to the suction of compressor and the pressure of ejecting fluid, temperature, the rotary speed of compressor, environment temperature etc..
The input of compressor is by by " the theoretical power needed during compression refrigerant ", " hot-fluid bulk diffusion " (refrigerant
Overheat, lose caused by the leakage of pump), " motor loss " while being revolving force (loss) by electrical power conversion, " machinery damage
Mistake " (frictional force of sliding part (bearing etc.)) is added together and obtained.Bearing designation is only changed, by under identical operating condition
Obtained experimental result, can interpolate that more superior to input small device.
In addition, as needed, the COP (cold power/input) for also adding cold power can be used to be compared.In addition, " bearing length
Degree L " is the axial length (reference picture 7) of the radial bearing 25 for the periphery (side) for supporting bent axle 23, and " diameter of axle D " is bent axle 23
Diameter (reference picture 4).
But, make advantage of the compressor miniaturization especially when product (for example, refrigerator) loads big but highly low developing
Compressor in the case of there is following problem.
In order to suppress the height of compressor, being compared to prior art needs to shorten bearing length (bearing length).But,
There is optimal ratio between bearing length, the diameter of axle (diameter of bent axle 23).In general bearing, the bearing length/diameter of axle
In the case that (following, to be used as α) is more than 2, the lubrication for being known as design bearing is good.
As shown in phantom in Figure 7, this is theory of the axle in bearing premised on the parallel bearing of keeping parallelism.The opposing party
Face, in the bearing of reciprocating compressor etc., the inclination of axle is produced due to crank-pin eccentric rotary, therefore according to operating condition
Shown in solid in such as Fig. 7, in the case of α ＜ 2.5, with α increases, the loss in bearing is reduced, even if α in α≤2.5
Loss in increase bearing also keeps relatively low value.Thus, it also can experimentally confirm that generation is above-mentioned in the range of α ＜ 2.5
Problem.
Subsidiary, in Fig. 7 solid line, α ＜ 2.0 situation is " metal is contacted " that bearing is in contact with each other with the solid of axle
The situation of region , α≤2.5 is to clamp the region of " fluid lubrication " that the solid of lubricating film (oil film) bearing and axle is in contact with each other,
2.0≤α ＜ 2.5 situation be lubricating film thickness is inadequate, bearing and shaft portion solid contact " boundary lubrication "
Region.
As the technical reason for producing such problem, there is also economy and achievable processing in the gap of bearing and axle
The margin of tolerance, also can not be extremely short even if bearing length shortens, and is unpractical in the design of bearing.
On the other hand, because bearing length shortens, the inclined angle increase of axle, is used as its knot if with identical gap
The inclination of the axle (bent axle) of fruit compressor becomes big, while loss increase in bearing, and the coefficient of friction in bearing becomes big, hinders
The smooth rotation of axle, can confirm that the increased tendency of vibration.
Therefore, because being the problem of being increased with the shortening of bearing by the inclined scope of axle and produced, if it is possible to press down
The inclination of axle processed just can solve the problem that problem.Therefore, in the present embodiment, by making the external diameter 2R of rotor 31 compare prior art
Greatly, it is the rotates effe that can be obtained representated by gyro (gyro) and solves the content of problem.
Fig. 8 is to represent " to vibrate " figure with the relation of " rotor radius/(height center of height center-rotor of piston) "
Table.Also, " vibration " is compared and obtained by operating compressor under identical operating condition and carrying out the vibration of compressor.Here
Identical operating condition refers to the suction of compressor and the pressure of ejecting fluid, temperature, the rotary speed of compressor, environment temperature
Deng.In general, compressor is connected in freeze cycle to be operated.Furthermore it is possible to be connected to as assembling object product
Refrigerator, simulation product in pattern refrigerating plant (so-called refrigerant operating) and verified., can as easy method
Verified with the operating in the case where making state (so-called air operating) of the suction with spraying atmosphere opening.
The measurement of vibration can be in operation compressor gabarit, installation foot nearby or near the connecting pipe of product,
Vibration measurement mechanism is set to measure on part etc. for carrying compressor, the position for the vibration effect for having compressor.In addition,
It can be the method that the compression mechanical part setting vibration measurement mechanism in the housing of compressor is measured.In addition, on shaking
The evaluation method of dynamic measurement, can also be with equivalent to a front and rear left side except the vibration of the flexible so-called above-below direction with spring
Vibration on the inclined direction of compression mechanical part of right direction is evaluated, and can also will be combined with the Quadratic Finite Element of those to three times
The vibration synthesis of member is evaluated.
In addition, " rotor radius R " is the radius (reference picture 4) of rotor 31, and " the height center H1 " of piston is piston 22
/ 2nd height and position (reference picture 4) of height, " the height center H2 " of rotor is 1/2nd of the height of rotor 31
Height and position (reference picture 4).In addition, following by rotor radius R/ (the height center H2 of the height center H1- rotors of piston)
=R/S is used as β.
As shown in figure 8, the situation of α ＜ 2.5 situation Yu α≤2.5 can be divided into.In the case of α≤2.5, with Fig. 8
In " ▲ " represent existing pattern compressor in, even in make β (=R/S) in 0.5~1.2 change in the case of, vibration
Big change can not be found in value.This is considered that, due to bearing length L (reference picture 4) long enough, the inclination of axle is difficult to produce
Raw, the influence that the diameter of rotor 31 is different is small.
On the other hand, in the case of α ＜ 2.5, in the compressor represented with "●" in Fig. 8, because bearing length shortens,
Vibration of compressor value in β=0.5 compared to existing pattern deteriorates.If in addition, can understand makes β value between 0.5 to 1.2
Change, then rotates effe increase, vibration values are successively decreased.In addition, in β≤0.8, can confirm that hold relative to existing compressor it is aobvious
Write sex differernce and vibration values can be reduced.
Therefore, in the present embodiment, after realization inhibits the compressor of flat pattern of height, suppression can not be kept away
That exempts from is tilted by the suppression bearing length L bearings produced, can be realized with low loss and the compression of the high bearing of reliability
Machine.
But, it is general situation that the axle of reciprocating compressor is slightly angled slided according to condition.Therefore, for bearing
Do not contacted with axle, therefore, to assure that bearing length L, miniaturization difficult.Therefore, in hermetic type compressor CMP, pass through β (=R/S)
≤ 0.8, using the rotates effe brought by the rotor 31 of flat pattern, axle (bent axle 23) in compressor operation can be suppressed
Tilt, can obtain making bearing (radial bearing 25) and the angle of axle (bent axle 23) to be compared to prior art closer to parallel
Effect.
In addition, in hermetic type compressor CMP, as α (=L/D) ＜ 2.5 by the length of bearing (radial bearing 25)
In the case that (bearing length L) significantly shortens, it will increase if assembling (in axial length) rotor oscillation of existing shape, pass through β
≤ 0.8, vibration can be suppressed, can further be minimized.
According to structure as above, in the present embodiment compressor CMP height dimension can be made to shorten, moreover,
The weight of compressor can be made by being accompanied by this.Weight is 7~8kg in existing compressor, in the present embodiment may be used
Suppress in about below 6kg.
Also, make height dimension as the appropriate pattern for the compressor CMP being used on refrigerator in the present embodiment

Weight is about the compressor that below 6kg, flat ratio are about less than 70%.As shown in figure 9, due to being the transverse direction relative to compressor
The flat pattern that size (Wp) height dimension (Tp) is constituted smallly, thus Machine Room 106 height dimension also coordinate the size and
Diminish.Moreover, flat ratio (Ob) is with " Ob=Tp/Wp × 100 " are represented.In addition, lateral dimension (Wp), height dimension (Tp) both may be used
To be the full-size or average-size of transverse direction and short transverse.
Because the underside wall 81b of heat insulating box 81 is formed approximately along the shape of Machine Room 106, therefore on Machine Room 106
The height on lateral extent underside wall 81b ground is lower than the situation of existing refrigerator.Therefore, it is possible to make to be located at the upside of Machine Room 106
The heat-insulated next door 84 of underside wall 81b and downside between Machine Room upper area SP short transverse length (Lp) it is elongated.
In addition, in order to as far as possible by condensate water discharging pipeline 107 close to the rear side of heat insulating box 81, condensate water discharging pipeline
Formed to 107 straight tube-likes.Because existing condensate water discharging pipeline is curved shape, therefore it can correspondingly make heat insulating box 81
Back face wall 81s is thickening.In contrast, being the condensate water discharging pipeline 107 of straight tube-like in the present embodiment, heat insulating box can be made
81 back face wall 81s is thinning.The length Lh of depth direction therefore, it is possible to make Machine Room upper area SP is elongated.Moreover, length
Lh is the length of the underside wall 81b for the heat insulating box 81 for being located at the upside of Machine Room 106 depth direction.In the present embodiment,
For using the compressor CMP side front end face of vegetable compartment 74 as the depth direction of starting point length.
In addition, the heat-insulated next door 84 in downside is connected with back face wall 81s by aqueduct 108, the section of aqueduct 108 is in downside
The inclined direction bending in the downward sides of bending section D of the heat-insulated side of next door 84, almost linearly extends and is connected to back face wall 81s.
Thereby, it is possible to make upside vegetables accommodating container 105u described later depth end 105e longer.
In this way, the compressor CMP of the flat pattern by using above-mentioned pattern in the present embodiment, due to machine can be made
The length Lp of tool room upper area SP short transverse is elongated, therefore, it is possible to make the storage volume of vegetable compartment 74 become greatly.In addition, removing
Because the length Lh for the depth direction that can make Machine Room upper area SP is elongated outside this, therefore, it is possible to further make vegetable compartment
74 storage volume becomes big.
Also, with these due to the shape formation upside along the vegetable compartment 74 expanded by Machine Room upper area SP
Vegetables accommodating container 105u, thus it is possible to store more vegetables.Certainly, downside vegetables accommodating container 105b shape also may be used
Changed as needed.Alternatively, it is also possible to which upside vegetables accommodating container 105u and downside vegetables accommodating container 105b is integral
Change, as a vegetables accommodating container.As long as in this case also along the vegetable compartment 74 expanded by Machine Room upper area SP
Shape formation vegetables accommodating container.

Height Lp have " Lm ＜ Lp " relation.Thereby, it is possible to become upside vegetables accommodating container 105u height dimension (depth)
Greatly, due to can further stretch out upside vegetables accommodating container 105u depth end 105e to Machine Room upper area SP, because
This can make upside vegetables accommodating container 105u storage volume become big.
Further, since Machine Room upper area SP expands to the back face wall 81s sides of heat insulating box 81, therefore, it is possible to make upside
Vegetable compartment side front end faces of the vegetables accommodating container 105u depth end 105e than compressor CMP is extended with length Gp1 to inner side,
Upside vegetables accommodating container 105u storage volume can be further set to become big.
Same the reasons why, upside vegetables accommodating container 105u bending sections of the depth end 105e than aqueduct 108 can be made
Extended with length Gp2 to inner side, upside vegetables accommodating container 105u storage volume can be made to become big.It is additionally, since aqueduct
108 almost linearly tilt from bending section D, therefore the inclined plane of aqueduct 108 and depth end 105e upper edge will not
Interference, can make depth end 105e further to entering deep drawing.
Further, since vegetable compartment 74 is maintained in+3 DEG C~+7 DEG C of temperature band, in order to be subcooled, electric heating is set to heat
Device, the electrothermal heater is arranged at the side of vegetable compartment 74 in the heat-insulated next door 84 in downside.Therefore, the heat of electrothermal heater flows through freezing
The side of room 73 can there is a possibility that the temperature of refrigerating chamber 73 rises.
In contrast, because Machine Room upper area SP in the present embodiment is to the back face wall 81s sides of heat insulating box 81
Expand, electrothermal heater can be made to be configured close to the expansion side.Thus, between lower freezer compartment 73 and electrothermal heater away from
From length, the heat of electrothermal heater can be made to flow through the ratio of the side of lower freezer compartment 73 and diminished, lower freezer compartment 73 can be suppressed
Temperature rise.
More than, make the compressor of the size of the compressor short transverse flat pattern smaller than lateral dimension on new design,
Increase foot is contributed to store up by the way that the compressor of the flat pattern to be configured in Machine Room to, made the height step-down of Machine Room
The capacity for hiding the storage volume of room is illustrated.
