For the refrigerator of said structure, its action and effect are described.

The design temperature of each area of insulation at first, is described.For stored refrigerated, be limited to 1～5 ℃ under being set in the not freezing temperature of refrigerating chamber 2 usually.According to user's setting, can change the temperature of switching chamber 16 and set, can be set at the temperature desired band that takes refrigeration, vegetable compartment temperature band from freezer temperature to.In addition, ice-making compartment 17 is independently to ice preserving chamber, can be set at-18 ℃～-10 ℃ higher temperature.

Vegetable compartment more than 3 is set in 2～7 ℃ that set with refrigerating chamber 2 identical or high slightly temperature.For freezing preservation, refrigerating chamber 4 is set in-22～-18 ℃ usually, but in order to improve preservation state, can be set in lower for example to-30 ℃ low temperature.

Each chamber is set in order to keep different temperature effectively, is separated by thermal wall, and thermal wall is by forming between case 13 and the outer container 14 in going into insulator 15 is foam filled.Insulator 15 has sufficient heat-proof quality, also has the effect of guaranteeing case body 1 intensity simultaneously.

Below, describe for the action of freeze cycle.According to the design temperature in the refrigerator, be used to signal from temperature sensor (not shown) and control substrate (not shown), begin or stop the cooling running.According to the indication of cooling running beginning, the cold-producing medium 104 of compressor 11 ejection HTHPs.The cold-producing medium 104 that is sprayed is by the heat release in condenser (not shown) of ejection pipe arrangement 31, and condensation liquefaction is reduced pressure by capillary 32, becomes the liquid refrigerant of low-temp low-pressure.Arrive the liquid refrigerant of evaporimeter 9, evaporation gasification in evaporimeter 9, the cold air by the low temperature after baffle plate (ダ Application パ) (not shown) distribution the carrying out heat exchange carries out each indoor cooling thus.

Below, describe for the action of compressor 11.

If to compressor 11 energisings, then power the rotating excitation field of utilizing stator 112 to produce, rotor 111 rotations to the stator 112 of electric element 110 by terminal 115, lead 116.Utilize the rotation of rotor 111, axle 130 the eccentric part 132 that is connected with rotor carries out rotatablely moving from the axle center off-centre of axle 130.The eccentric motion of axle 130, be transformed to reciprocating motion by the linkage unit 137 that is connected on the eccentric part 132, become the reciprocating motion of the piston 136 on the other end that is connected linkage unit 137, piston 136 changes the volume in the discharge chambe 134, carries out the suction compression of cold-producing medium 104 simultaneously.

The volume of piston 136 suction in a reciprocating motion, ejection in discharge chambe 134 is called the inflator volume, changes by the cooling capacity of inflator volume size.

In the refrigerator that carries out above action, utilize the compressor 11 of elastomeric element 107 and pin 106 supportings, carry in the recess 27 of end face 23 that strides across refrigerator and back side 28a formation.Need make concave depth (highly) is the bottom and the minimum clearance of height, upper container 102 and the end face cover 34 of the minimum clearance that face 28b is set, compressor 11, the thickness of end face cover 34 of the following container 101 of compressor 11 at least.For fear of compressor 11 and face 28b is set or end face cover 34 between contact, minimum clearance is necessary, if from the minimum wall thickness (MINI W.) of intensity aspect decision end face cover 34, then concave depth (highly) is by the height decision of compressor 11.

On the other hand, in the case of refrigerator, because recess 27, protuberance 30b protrudes.If protuberance 30b is big, taking in property variation then, simultaneously when opening refrigerating chamber revolving door 5 and observing in the case of refrigerating chambers 2, since the protrusion of protuberance 30b, degraded appearance.Therefore, need to reduce the technology of compressor 11 height.

Height for compressor 11 carries out specific description.Compressor 11 uses the steel plate of 2～4mm on following container 101, upper container 102, adding up to has 7mm approximately.Following container 101 and upper container 102 form the shape that above-below direction has curvature respectively.This is in order to make the living space that refrigerator is set comfortable, the preferred low style of noise, owing to make container have curvature, the rigidity of container, eigenvalue rise, and the noise that resonance produces is suppressed.With regard to its curvature, radius is approximately from R100mm to R150mm, and in order to obtain this curvature, needing the side is that about 13mm is strong.

Below, in the bottom storage of closed container 103 refrigerator oil 105 is arranged.Refrigerator oil 105 is approximately enclosed 200～250ml in order to guarantee compressor 11 running under various conditions, highly accounts for 20mm.And if refrigerator oil 105 contacts with electric element 110, then unusual input increases, so as being used to make it discontiguous space length, need be about 9mm.

In the refrigerator that compressor 11 is loaded on the refrigerator end face 23, owing to the ear location of compressor 11 near the user, the noise that inhibition reduces compressor 11 just becomes more important.That is, the rigidity that improves closed container 103 is very important, on the other hand, from improving the viewpoint of reliability, need be used to make refrigerator oil 105 and electric element 110 discontiguous spaces.Thus, with the 20mm of 13mm, curvature and the oil of the 7mm of thickness of slab, curvature with guarantee that the necessary 9mm of space length adds and be in the same place that 49mm is exactly necessity, if size less than this size, then is not suitable for aspect characteristic.

Therefore, the height of compressor 11 is roughly determined by electric element 110 and compressing member 113.Compressing member 113 can make piston 136 or linkage unit 137, axle 130, bearing portion 135 compactnesses by reducing the inflator volume, if but the inflator volume reduces, and then refrigerating capacity diminishes.In the present embodiment, in order to obtain big ability,, make compressing member 113 compactnesses by turning round with the rotating speed that is higher than source power supply frequency (, being 50Hz or 60Hz) in Japan with little inflator volume.More particularly, because it is about 30% to dwindle the inflator volume, the reduced of piston 136, the load that acts on the axle 130 also reduces, so can shorten the length of bearing portion 135 of the load of supporting axis, can constitute electric elements 110 near compressing member 113.By utilizing the high rotating speed of frequency control smoothly, in inventor's design, can be with its compactness 5 to 10mm.

In addition, utilize the setting of a plurality of rotating speeds of the electric element 110 of frequency control way, not necessarily must comprise and the suitable rotating speed of frequency that is higher than source power supply frequency (50Hz or 60Hz) in Japan.

Promptly, with the combination of the upper limit of the frequency of a plurality of settings as the setting that is not higher than source power supply frequency (being not limited in Japan), expectation energy-saving effect and quiet effect, about miniaturization, thickness corresponding to the electric element 110 that utilizes above-mentioned frequency controlization reduces effect, and the combination of the densification of the inflator volume that does not adopt compressing member 113 is on the contrary also arranged.

Below, describe for electric element 110.In the induction conductivity that the left side of the center line of Fig. 6 is represented,, then can not produce the necessary torque of running of compressor 11 if the long-pending thick H1 and the H4 of stator 180 or rotor 182 are little.Relative therewith, by the frequency-conversion and speed-regulation motor of use use permanent magnet 151 on rotor 111, the necessary exciting current of torque that no longer needs to rotate, therefore, the long-pending thick L1 of stator 112 and the long-pending thick L4 of rotor 111 can be reduced, electric element 110 compactnesses can be made.More specifically, induction conductivity must be at rotor-side (two-dimentional side) streaming current.In order to obtain this exciting current, need high long-pending thickly, still,, therefore do not need to be used to produce the exciting current of torque because frequency-conversion and speed-regulation motor has magnet in two-dimentional side, can reduce amass thick.

Moreover the coiling 162 of the stator 112 of electric element 110 is from stator core 161 outstanding size L2, L3, compares with outstanding size H2, the H3 of the coiling 183 of twining of distributing, and reduces significantly.Promptly, concentrate in the winding at salient pole, between the notch of coiling, but do not concentrate on one by one salient pole portion between not striding across, twine densely, therefore, do not have shown in L2, L3, to reduce significantly because coiling strides across the protuberance of the coiling that causes between the notch, the overall height of stator 112 descends, and can further make electric element 110 compactnesses.

Moreover, if in the permanent magnet 151 of frequency-conversion and speed-regulation motor, use the magnet of terres rares,, has magnetic flux density and is about 4 times, energy product and be excellent magnetic characteristics such as about 10 times then with respect to general ferrimagnet, even little, also can access sufficient characteristic.Therefore, can further reduce the height L5 of permanent magnet 151 and the height of stator L1, can make electric element 110 further compact.

Moreover, in the present embodiment, being formed with rotor recesses 111a in compressing member 113 sides of rotor 111, bearing portion 135 extends out in this rotor recesses 111a.Thus, do not shorten the length of bearing portion 135 and make electric element 110 and compressing member 113 overlapping on the perspective plane of short transverse, be configured, thereby can significantly reduce the height of the Machinery Ministry integral body that comprises electric element 110 and compressing member 113, can not reduce compressor reliability, further reduce the height of compressor.

Further describe particularly, in inventor's design, in induction conductivity, the long-pending thick of stator 180 is 42mm, and coiling terminal height H 2, the H3 of coiling 183 are 25mm, and the height H 4 of rotor 182 is 65mm.Otherwise in frequency-conversion and speed-regulation motor, the long-pending thick L1 of stator 112 is 26mm, under the situation of same use rare earth magnet, further reduce, L1 is 16mm, coiling terminal height L2, the L3 of the coiling 162 of stator 112 twine if use salient pole to concentrate, and then L2, L3 are 9mm.In addition, the long-pending thick of rotor 111 is 35mm, if use rare earth magnet, then can be decreased to 20mm, therefore, compares with the compressor of induction conductivity, and maximum can be dwindled 58mm.

Moreover as mentioned above, in compressing member 113 sides of rotor 111, with the degree of depth formation rotor recesses 111a over half of rotor height direction, bearing portion 135 extends out in this rotor recesses 111a.Therefore, at long-pending thick 35mm (if the use rare earth magnet that is contracted to rotor 111, then be 20mm) the basis on, the height of Machinery Ministry further can be contracted to about 10mm as the extension of bearing portion 135, therefore, can make altogether about the reduced height 25mm of Machinery Ministry integral body.

Like this,, can not improve overall height and prolong the sliding length of axle 130 and bearing portion 135, can dwindle the compression load that is added on the axle 130, therefore, can improve the reliability of compressor by prolonging the extension of bearing portion 135.

But,, then, cause the standing part of rotor 111 on axle 130 to shorten because the degree of depth of rotor recesses 111a increases if prolong the extension of bearing portion 135.

Particularly as present embodiment, compressing member 113 on top, electric element 110 is arranged in the compressor of this configuration in its underpart, the rotor that is possessed in the electric element 110 of bottom only utilize and axle between bed knife keep.Therefore, for example, as induction conductivity, make electric current flow through internal rotor and obtain under the situation of motor of type of magnetic force in use, the heating of rotor 111 increases during running, because thermal expansion, might make on the rotor 111 and come off from axle 130, so shorten the method for the standing part of rotor 111 on axle 130 significantly, on reliability, have problems, inadvisable.Research according to the inventor, under the situation of using permanent magnet 151, electric current is not flowed through rotor 111 inside and is obtained magnetic force by permanent magnet, so heating reduces significantly, and, compare with induction conductivity, owing to highly reduce weight saving, even, also can keep rotor 111 so shorten standing part significantly.For example, even standing part is foreshortened to about the 6mm below 20% of rotor 111 overall height 35mm, also can have sufficient bed knife.Therefore, vibration that the heating when not having owing to running, conveying etc. produce or impact etc. make rotor 111 take place from the situation that axle 130 comes off.Can realize improving reliability that the sliding length that increases axle 130 and bearing portion 135 causes, guarantee rotor 111 and axle 130 bed knife and deposit, and can reduce the height of the Machinery Ministry integral body that constitutes by compressing member 113 and electric element 110.

In addition, by shortening the standing part of rotor 111, can improve the supply capability of the oil supply mechanism that is arranged on axle 130 inside (not shown).This be because, bearing portion 135 and axle 130 slide bottom, with refrigerator oil 105 between distance, be to be used for refrigerator oil 105 is drawn lift till spools 130 the helicla flute that is used for fuel feeding, this lift shortens significantly.Thus, the sliding part between axle 130 and bearing portion 135 and improve by the supply capability of axle 130 to the sliding part of compressing member 113 etc. is achieved the raising of reliability.

The passing through to carry frequency-conversion and speed-regulation motor of present embodiment and under the situation with lower rotation running compressor 11, with the ratio that is reduced to of rotating speed, the problem that the supply capability when occurring using the centrifugal force of axle to carry out fuel feeding descends.By raising supply capability like this, even under situation, also can stably supply with refrigerator oil 105 to sliding part with lower rotation running compressor 11.

Like this, realization simultaneously prevents coming off of rotor 111 and improves the reliability of fuel feeding, in order to realize the miniaturization on the short transverse, on the rotor 111 of overall height 35mm, use permanent magnet, and, under the rotating speed of 50Hz, change the standing part of rotor 111 and axle 130, carry out the affirmation test of fuel delivery.

As a result, be that 80% situation of rotor overall height is compared with rotor 111 and axle 130 standing part, under 50% the situation that be the rotor overall height, fuel delivery improves about 3%, begins to obtain the effect of certain fuel delivery raising; Moreover under the situation that is rotor overall height 30%, fuel delivery improves about 5%; Be that fuel delivery is increased to about 8% under 15% the situation.

And the affirmation test of fuel delivery is carried out in the raising of fuel feeding reliability when rotating in order to confirm that the frequency control compressor is low under 20Hz.As a result, be that 80% situation of rotor overall height is compared with the rotor 111 and the standing part of axle 130, be fuel delivery improves about 5%, begins to obtain the effect that certain fuel delivery improves under 50% the situation; Moreover, be under 30% the situation, fuel delivery improves about 10%; Be that fuel delivery is increased to about 15% under 15% the situation.

Like this, in rotor, extend out, shorten refrigerator oil 105 is drawn to the spiral fluted lift that is used for fuel feeding, can improve the fuel feeding reliability by making bearing.When normal rotation, the low rotation, all making standing part is below 50% of rotor overall height, begins to make to obtain effect, preferably by being below 30%, obtains certain effect.In addition,, be contracted to about 15%, then can further strengthen effect, on the other hand, might begin to occur influence aspect the reliability of rotor maintenance if further shorten standing part.Therefore, when adopting standing part, need fully to confirm, preferably do not make standing part be lower than 15% as far as possible.If below 10%, then the reliability of rotor maintenance reduces significantly, avoids so should give.

Particularly when low the rotation, shorten refrigerator oil 105 is drawn to the spiral fluted lift that is used for fuel feeding, for improving fuel delivery, effect highly significant.In recent years, the progress of energy-conservationization of refrigerator, the compressor operation that plays the low rotation of energy-conservationization effect becomes main flow gradually.But, when this low rotation,, improving aspect the fuel delivery because fuel delivery must descend, carried out various researchs for the oil supply structure of compressor inside.As present embodiment, utilizing the starting point that shortens standing part raising fuel delivery is following technology, except that playing the effect that reduces compressor overall height and decline center of gravity, also plays a plurality of beneficial effects such as improving the fuel delivery effect when obtaining low the rotation.

In order to reduce compressor 11, make the top of compressor 11 be lower than the end face 23 of case body 1, the electric element 110 that makes compressor 11 uses the rotor 111 of permanent magnet 151 as electric element 110 for to comprise the frequency control drive electric motor of the high-frequency a plurality of rotation speed operation that are higher than the source power supply frequency at least.By compresses machine 11, can reduce to be provided with the height of the recess 27 of compressor 11, therefore, the taking in property of refrigerator lower floor is improved.Simultaneously, because the protrusion of protuberance 30b accommodation space side in the refrigerator of recess 27 diminishes, outward appearance improves, and the accommodation space in the refrigerator enlarges, thereby taking in property also is greatly improved.

In addition, in a plurality of salient pole portion 171 of the stator core 161 that constitutes compressor 11 stators 112, twine coiling 162 across insulator, become salient pole and concentrate the situation of winding-type, and the situation of in permanent magnet 151, using rare earth magnet, by the further compresses machine 11 of both of these case.As a result, because can reduce to be provided with the height of the recess 27 of compressor 11, improve the taking in property of refrigerator lower floor, reduce protuberance 30b accommodation space side outstanding in the refrigerator of recess 27 simultaneously, outward appearance improves, and the accommodation space in the refrigerator enlarges, and taking in property increases substantially.

In the compressor 11 of present embodiment, compressing member 113 flexibly is bearing in compressing member 113 and electric element 110 on the closed container 103 by spring 114 for the reciprocating motion type of the piston 136 that possesses discharge chambe 134 and move back and forth in discharge chambe 134.

As mentioned above, utilize the supporting structure portion element in addition of compressing member 113 and electric element 110, reduce the height of compressor 11, can access following effect thus.Promptly, compare with rotary compressor etc., can be easy to realize low vibrationization, and structurally, even use the refrigerator of compressor top layout type aspect height dimension big or small being suitable for reciprocating motion type compressor, also can reduce the height of compressor integral body with restriction.Thus, can be reduced in the vibration that becomes big problem when compressor 11 is configured in top.Therefore, can provide a kind of refrigerator, even vibration might be delivered to the refrigerator of the compressor top layout type on the case body 1, also can eliminate user's discomfort, dwindle the height of the recess 27 that compressor 11 is set simultaneously, improve the taking in property of refrigerator lower floor, ease of use is good.

In addition, in the present embodiment, reciprocating motion type compressor is inner low-pressure type, and electric element 110 is provided in the below in the closed container 103, by support 113a and spring 114 as support unit, flexibly is bearing on the closed container 103 simultaneously.In addition, as shown in Figure 5, compressing member 113 is provided in the top of electric element 110, but simultaneously by the bleed pipe 144 as the high press fit pipe that is made of the elastic bearing shape, is connected with closed container 103.Here, so-calledly can flexibly mounted shape refer to nonlinear shape, for example, have the curve shape of parts such as U font.Moreover, on the support unit of compressing member 113 in electric element portion 110 is configured in closed container 103 as the vibration of compressor source.Thus, compare, can further increase distance apart from elastic supporting part with the situation of direct elastic bearing compressing member 113.In addition, owing to decay during the stator of the vibration that compressing member 113 produces by the high electric element 110 of rigidity, and transmit to the outside of compressor from the support unit of compressor, the vibration of compressor can be reduced.

In addition, owing to be can flexibly mounted shape as the bleed pipe 144 of compressing member 113 inner high voltage pipe arrangements, the vibration of compressing member 113 be because bleed pipe 144 decay, and to the transmission of the outside of compressor, so can further reduce the vibrations of compressor.

In addition, pin 106 is by support 113a and spring 114 elastic bearings as closed container 103 interior support parts, simultaneously, the center of gravity A of compressor above-below direction, with the contact-making surface 106a of the pin 106 of compressor and elastomeric element 107 apart from B, less than the distance C of the center of gravity A and the holding components lower surface 113b of compressor above-below direction.Thus, the vibration amplitude of compressor, minimum near center of gravity A, along with leave from center of gravity vibration become big center of gravity A around, the compressor body vibration, therefore, less than than the lower surface of the support unit of supporting machinery portion more near the pin 106 of center of gravity A and the vibration amplitude of the contact-making surface of elastomeric element 107, moreover, can reduce the vibration that is delivered to refrigerator.

In addition, by in rotor 111, using permanent magnet 151, reduce the height of rotor 111 and making stator 112 concentrate winding-type, reduce stator 112 mode highly, can reduce the center of gravity A of electric element 110 integral body as salient pole.

Under the situation of stator 112 for the winding that distributes, because coiling is outstanding upward to the installation portion of stator 112 from cylinder portion 133, the size that need make cylinder portion 133 foots is more than the size that coiling is given prominence to.Otherwise, concentrating winding-type by stator 112 being set to salient pole, can shorten as the pin of cylinder portion 133 to the cylinder portion 133 of stator 112 installation portions, also can reduce the center of gravity A of compressing member.

Moreover the bearing portion 135 by prolonging cylinder portion 133 can further reduce cylinder portion 133 downwards to the extension of rotor recesses 111a, and A lowers the center of gravity.

Like this, further reduce the center of gravity A of compressor internal mechanical portion, and make the pin 106 that the closed container 103 as the compressor outside possesses and the contact-making surface 106 of elastomeric element 107 be positioned at the more position of top, thus, can further shorten center of gravity A, and the contact-making surface of pin 106 and elastomeric element 107 between apart from B, further reduce vibration from compressor to the refrigerator transmission.

Usually, with compressor configuration in the refrigerator of the type on top, on the one hand do one's utmost to require the miniaturization of compressor overall height, also very important for the situation that must realize low vibration, low noise simultaneously on the other hand.The inventor is for being used to realize that the key element of compressor miniaturization carried out various considerations.Aspect internal structure, in rotor 111, use permanent magnet 151.Thus, can utilize axle 130 to keep the maintenance effect of rotor 111, bearing portion 135 is further extended out in rotor, can realize the reduction of internal height.In addition, externally configuration aspects erects by making the mounting surface of pin 106 on elastomeric element 107, with regard to regard to the state that is provided with of refrigerator, also can realize the miniaturization of overall height, can realize the low oscillating mode light duty compressor of centre of gravity, high supporting stability.

In addition, in the present embodiment, the contact-making surface 106a of the pin of compressor and elastomeric element is positioned at the top of support unit lower surface 113b.Thus, the vibration of compressor is through support unit, transmits to the below as the Machinery Ministry of vibration generation source, and then, direction changes upward, transmits to elastomeric element 107 via pin 106.Thus, the transfer of vibration road is through becoming complicated, and vibration is further decay in bang path.Moreover, owing to can increase pin 106 from the support unit to the compressor and the distance till the contact-making surface 106a between the elastomeric element 107, especially decay is transmitted in the vibration in high-frequency zone, pin 106 reduces with the vibration amplitude of the contact-making surface 106a of elastomeric element 107, further reduce the transmission of vibration, the high-quality refrigerator that does not have vibration beastly and produce the noise that causes owing to vibration can be provided to refrigerator.

In addition, as shown in Figure 8, pin 106 comprises: the following 106d of elastomeric element configuration that is fixed on the stationary plane 106b on the closed container 103, the flexure plane 106c that erects upward and engaging elastomeric element.Thus, by utilizing simple pin to be bent to form bend, pin 106 is positioned on the stationary plane 106b that joint waits good closed container 103 bottoms of operation, makes that the face of configuration elastomeric element be more near below the elastomeric element configuration of center of gravity A, makes very easy.

In addition, pin 106 is fixed on the stationary plane 106b on the closed container 103, is positioned at the downside as the lower surface 113b of the stationary plane of bottom container 101 support unit 113a.Vibration as the compressing member 113 in vibration of compressor source, via electric element 110, again via the spring 114 that utilizes support unit 113a to support, even in closed container 103, also can be delivered to and be on the stationary plane away from the support unit 113a on the position that adds vibration source, therefore, vibration is decayed significantly.

Moreover after general horizontal direction was extended, 106c erected to vertical direction pin 106 through bend from stationary plane 106b, after the general horizontal direction bending, had the following 106d of elastomeric element configuration again.Utilize this shape, from being fixed on the stationary plane 106b on the closed container 103, to the contact-making surface 106a of elastomeric element 107 till, the transfer of vibration path becomes complicated and is extended, vibration is transmitted and is decayed.Moreover, 106d is positioned at more the position near the center of gravity A on the compressor above-below direction below the elastomeric element configuration, the length of elastomeric element 107 also obtains very abundant simultaneously, therefore, on elastomeric element 107, vibrate and also can fully decay, can fully reduce the transmission of vibration, the high-quality refrigerator of the noise that does not have vibration beastly or take place to cause owing to vibration can be provided to refrigerator.

In the present embodiment, the height that erects in vertical direction of pin 6 is 24mm.This is about 16% of a compressor overall height.

In addition, in the present embodiment,, be positioned at the top of the lower surface 113b of support 113a for the height that erects of this vertical direction.The bottom and the support 113a that are fastened on the spring 114 on the support 113a are chimeric, are fixed on the closed container in rubber-like mode not, therefore, preferably are positioned at the below of the bottom of rubber-like spring with respect to closed container.

In addition, along with vertical direction erect increasing of height, the distance that erects part increases, so, be difficult to obtain erecting the high rigidity of part.Especially under the situation that is subjected to producing from the impulsive force of the horizontal direction of outside by switch refrigerator doors etc., be the center with the contact-making surface 106a of pin 106 and elastomeric element 107, produce the crooked forwards, backwards oscillation phenomenon of above-below direction.As a result, generation is concentrated to the stress that pin 106 erects the part periphery, might reduce reliability.Therefore, the inventor thinks, if consider external impact force, preferably with pin 6 vertical direction erect height setting the compressor overall height below 30% about, can improve the reliability of compressor.

In addition, because the formation of bend 106c, from the stationary plane of pin 106 on closed container 103, the distance till below the elastomeric element configuration of configuration elastomeric element 107 can prolong.Increase owing to transmit distance from the vibration of stationary plane 106b, especially the transmission in high-frequency zone is decayed, and can further eliminate the vibration of transmitting to refrigerator.Therefore, can provide easy manufacturing with low cost, can reduce vibration, not have vibration beastly and produce because the high-quality refrigerator of the noise that vibration causes to the refrigerator transmission.

Moreover, by the rib 106e across 106d extension below bend 106c and the elastomeric element configuration is set on pin 106, the rigidity of pin 106 improves, the eigenvalue that pin 106 self has improves, because pin 106 self is difficult to vibration, therefore, can further reduce stationary plane simultaneously from closed container 103, via pin, to the vibration of elastomeric element, refrigerator body transmission.In addition, the formation of rib can utilize the pressurization that is easy to make to carry out, and the intensity of pin is improved, and therefore, also improves because the problem that produces the pin distortion is impacted in the conveying of refrigerator.

Therefore can provide easy manufacturing with low cost, can reduce vibration, not have vibration beastly and produce because the high-quality refrigerator of the noise that vibration causes to the refrigerator transmission.

As mentioned above, key element as the miniaturization on the short transverse of compressor 11, be broadly divided into corresponding to the viewpoint of electric element 110 with corresponding to the viewpoint of compressing member 113, from the balance of the viewpoint of the required value that highly reduces and other characteristic or quality aspect, select to adopt these two key elements or any one key element to get final product simultaneously.

For example, the height key element that is wrapped in electric element 110 with the durable reliability that does not require degree of precision, the main cause that is difficult for becoming noise and vibration, reduction is the method that main body constitutes, compressor 11 is being configured in the structure on top, suppress to realize for the influence of noise and vibration, simultaneously miniaturization aspect on, have advantage.

On the other hand, utilize under the situation that the densification of compressing member 113 achieves the goal, also can expect to realize the miniaturization of cost degradation, aspect the ratio of performance to price, have advantage in hope.

In addition, as mentioned above, under the situation of top that compressor 11 is configured in refrigerator case body 1, need consider the noise and the vibration that are added on the current refrigerator near the position of user's ear.That is, reduce the miniaturization of compressor 11 height, not extremely important with the combination of vibrating the miniaturization key element that impacts to the noise of refrigerator.In the structure of structure that supports electric element 110, compressing member 113 or supporting closed container 103, make great efforts to make noise, vibration to be in the inhibition direction, realizing the reduction of height simultaneously, do not adopt noise, vibration to bring dysgenic design that reduces height on the contrary, also is effective.

Below, for accommodation space 29a of the refrigerator the superiors and second layer accommodation space 30a, describe.The inside of the accommodation space 29a of the superiors is that hand is difficult to position contacting, even block the inboard of the superiors' accommodation space 29 by protuberance 30b, ease of use can variation yet.Certainly,, food etc. can be accommodated in the scope that hand can contact, prevent to surpass the shelf-life and it is forgotten ease of use improves on the contrary because depth shoals.

On the other hand, if protuberance 30b is side-prominent to second layer accommodation space 30a, when then opening refrigerating chamber revolving door 5, see protuberance 30b, degraded appearance.In addition, in the inboard that food etc. is accommodated in second layer accommodation space 30a or when taking out food etc., exist food midway etc. to block, be difficult to carry out the inconvenience of access.Dividing plate bottom 30d by making the accommodation space 29a of the superiors and horizontal plane as the protuberance 30b of recess 27 indoor diapire faces on essentially identical horizontal plane, connect in appearance substantially continuously.Therefore, can not experience the outstanding of protuberance 30b, outward appearance improves, and compressor 11 also can be housed in the recess 27 of regulation.

Except outstanding, the outward appearance that can not feel protuberance 30b improves, be lower than the collecting articles such as food of the height in second layer accommodation space 30a front, can successfully be accessed to the inboard, there is not inconvenience.

If further specify size, it is that the height of 25mm, the accommodation space 29a of the superiors is that 140mm, block board thickness are 10mm that design makes end face 23 and heat insulation wall thickness in the refrigerator, and then the distance till the 30d of the bottom of the dividing plate from end face 23 to the accommodation space 29a of the superiors is 175mm.In addition, owing to be topmost in the refrigerator, take out at the tinned drink specification product of the 350ml that considers fell sideling height 123mm, diameter 66mm and with it, decision is taken out under the situation of size, is 140mm.The thickness of the face that is provided with 28b that makes the compressor 11 of recess 27 is that 20mm, compressor 11 are 2mm with the thickness that the gap that face 28b is set and its gap with end face cover 34 inner faces respectively are 3mm, end face cover 34, on same horizontal plane, the maximum height that then can be accommodated in the compressor 11 in the recess 27 is 147mm substantially for the dividing plate bottom 30b of the accommodation space 29a of the superiors and the indoor diapire face 30c of recess 27.

Corresponding, further specify the size of compressor 11, the following container 101 of closed container 103 adds up to 7mm with the thickness of upper container 102, the height that being used to of upper container 102 obtains curvature is 14mm, certain top of the discharge chambe 134 of cylinder portion 133 is 39mm, the size of bearing portion 135 a certain sides till stator 112 installed surfaces is 20mm, the height of stator 112 is 26mm, size from the lower end of stator 112 to the lower end of rotor 111 is 9mm, distance from the lower end of rotor 111 to refrigerator oil 105 is 9mm, and the height of refrigerator oil 105 is 20mm.If with these totals, then be 144mm, can be housed in the height space in the above-mentioned recess 27 of present embodiment.

Because the height dimension of this compressor is approximately more than the 190mm in the refrigerator of existing normal capacity, so can make height dimension miniaturization significantly.Especially use the frequency-conversion and speed-regulation motor that uses permanent magnet 151 on the rotor 111 that comprises a plurality of rotation speed operation that are higher than the source power supply frequency, can constitute the compressing member 113 and the electric element 110 of compressor 11 according to suitable dimensions.In addition, can be kept for keeping the rigidity of the noise of good closed container 103, compressor 11 is housed in the recess 27 of regulation simultaneously.The result, by making as the horizontal plane of the protuberance 30b of recess 27 indoor diapire faces and dividing plate bottom 30d on essentially identical horizontal plane, also can connect substantially continuously in appearance, thereby the outstanding good refrigerator of outward appearance that can not feel protuberance 30b can be provided.

Moreover, by improveing the employing short transverse miniaturization key element of electric element 110, also can reduce the problem of guaranteeing along with the noise and the vibration aspect reliability of the change of compressing member 113 samples as main body.Especially for the top that compressor 11 is configured in refrigerator, the refrigerator of the form of noise and vibration might appear, the problem of noise and vibration that can be resolved, realize the effective ways of the miniaturization of height simultaneously.

In addition, in the present embodiment, the ground height of case body 1, be end face 23 apart from the height on ground be below the 1800mm.This highly be Japanese women based on standard heights stretch out one's hand upward contact range maximum height and set.

If end face 23 is higher than 1800mm apart from the height on ground, even then increase compressor 11 height dimension, do not carry out densification, be housed in easily in the recess 27, but the ease of use on opposite refrigerator top further worsens, and what be difficult to realize simultaneously refrigerator integral body takes in efficient and ease of use.

In the present embodiment, the height of end face 23 apart from ground is controlled at below the 1800mm, at first consider the ease of use in the refrigerator, in this altitude range, make the height dimension densification of compressor 11 then as far as possible, thus, can bring into play the advantage that suppresses to occupy the inboard useful space of refrigerator to greatest extent, can be increased to greatest extent taking in efficient.

In addition, in the present embodiment, be provided with the rib 106e that strides across 106d below the configuration of bend 106c and elastomeric element and extend.This flank 106e is preferably formed and strides across the rib 106e that extend at least two places among the 106d below the configuration of stationary plane 106b, flexure plane 106c and elastomeric element, so also can extend to foot section and bend 106c on the horizontal plane of stationary plane 106b.

Moreover, under the situation that the trihedral of 106d becomes below rib 106e strides across stationary plane 106b, flexure plane 106c and elastomeric element disposes, can further improve rigidity.Especially under the situation above 106d is configured in significantly below the elastomeric element configuration, though the distance of 106d increases substantially below the configuration from stationary plane 106b to elastomeric element, but become rib by striding across trihedral like this, make the rigidity of pin be improved, for the purpose that realizes reducing vibration, noise, very effective.

Fig. 9 A is the schematic cross-section of the refrigerator of embodiment of the present invention 2, and Fig. 9 B is the major part sectional view of the refrigerator of embodiment of the present invention 2.

In addition,, use identical symbol, omit detailed explanation for the structure identical with Fig. 1.

In addition, for not describing one by one with common structure and the action effect of embodiment 1, so long as be applicable to present embodiment, be not to produce irrational item, all include identical content.

Shown in Fig. 9 A, case body 1 has the ventilating duct 201 that is connected with recess 27 under end face 200.In addition, compressor 11 is arranged on the face that the is provided with 28b of recess 27, on the lower surface 202 that makes the top 203 of compressor 11 be in to be higher than ventilating duct 201, the position that is lower than end face 200.Condenser 204 is configured in the top of ventilating duct 201.Condenser 204 is communicated with ejection pipe arrangement 31.The upper surface of the end face 200 of ventilating duct 201 and the end face cover 34 of recess 27 on same horizontal plane, perhaps constitutes one substantially.In addition, ventilating duct 201 sucks air from inlet port 205, by being provided with the recess 27 of condenser 204 and compressor 11, carries out exhaust from the outlet 206 of end face cover 34.

In aforesaid structure, since with the top of compressor 11 be configured in the end face 200 that is lower than case body 1, on the position of the lower surface 202 that is higher than ventilating duct 201, accommodate the projection to the refrigerator inboard of the recess 27 of compressor 11, the projection that is protuberance 30b diminishes, and can use space in the refrigerator more effectively.

In addition, design and make the height of compressor 11 to be accommodated in the height of ventilating duct 201 and the height of recess 27 are added in the scope of total height together.For example, in large-scale freezer etc., even all included in various miniaturization factors with embodiment 1, and must adopt under the situation of larger-size compressor aspect the refrigerating capacity, also can expand the free degree of design, even in large-scale freezer, also can easily provide the high refrigerator of taking in property that compressor 11 is accommodated in the end face rear.

On the other hand, the necessary ventilating duct 201 of the cooling of compressor 11 is configured on the end face 200 that the hand in the refrigerator case is difficult to contact, therefore, can be except that taking in purposes, effectively utilize end face 200 near.In addition, since with the top 203 of compressor 11 be configured in the end face 200 that is lower than case body 1, on the position of the lower surface 202 that is higher than ventilating duct 201, so the top of compressor 11 is configured in the perspective plane on the direction of ventilation of ventilating duct 201, can cool off the highest top 203 of temperature in compressor 11 effectively, characteristic, the reliability of compressor 11 also are improved.Moreover by condenser 204 being configured in the inside of ventilating duct 201, the exothermal effect of condenser 204 improves, and can improve the efficient of system.

Below, be conceived to accommodation space 29a of the refrigerator the superiors and second layer accommodation space 30a.The inboard of the accommodation space 29a of the superiors is the position that hand is difficult to contact, and promptly uses protuberance 30b to block the inboard of the accommodation space 29a of the superiors, also can not influence ease of use.Certainly,, collecting articles such as food can be accommodated in the scope that hand can contact, prevent to surpass the shelf-life and it is forgotten ease of use improves on the contrary because depth shoals.On the other hand, if protuberance 30b is side-prominent to second layer accommodation space 30a, then when opening refrigerating chamber revolving door 5, see protuberance 30b, outward appearance degenerates.In addition, in that food etc. to be accommodated in second layer accommodation space 30a inboard or when taking out food etc., possible food etc. block halfway, are difficult to carry out access.Therefore, the indoor diapire face 30c that makes the dividing plate bottom 30d of the accommodation space 29a of the superiors and recess 27 is on essentially identical horizontal plane, outward appearance is connected substantially continuously, therefore, can not feel that protuberance 30b's is outstanding, outward appearance improves, and can also compressor be accommodated in this state in the recess 27 of regulation.

In addition, this essentially identical horizontal plane is meant, except the dividing plate bottom 30d of the indoor diapire face 30c of recess 27 and the accommodation space 29a of the superiors on the essentially identical horizontal plane, the indoor diapire face 30c that also makes recess 27 sometimes with as the upside of the dividing plate of the bottom, space of the accommodation space 29a of the superiors on essentially identical horizontal plane.For example, by making the superiors' dividing plate 29 below the diapire face 30c of the indoor of recess, can avoid the collision state of indoor diapire face 30c on fore-and-aft direction of the superiors' dividing plate 29 and recess.By the dividing plate that forms the accommodation space 29a of the superiors is positioned near the indoor diapire face 30c of recess 27, can connect continuously in outward appearance, can not feel protuberance 30b outstanding, aesthetic property is better, under this state, also compressor can be accommodated in the recess 27 of regulation.

In addition, the highly low collecting articles such as food in front than second layer accommodation space 30a can successfully be accessed to the inboard, do not have inconvenience.

Because the accommodation space 29a of the superiors is positioned on the higher position, be difficult to take in, preferably reduce the height of incorporating section as far as possible.Therefore, if be made as the minimum constructive height of the specification product (height 123mm) of the tinned drink that can take in 350ml, the height of the incorporating section of the accommodation space 29a of the superiors at top leaving gap 2mm, is set at 125mm, can effectively utilize space in the refrigerator the most.

In the refrigerator that Fig. 9 A represents, further verify size particularly.

The distance that begin from the dividing plate of the accommodation space 29a of the superiors bottom 30d till the upper surface of end face 200 that comprises ventilating duct 201 and end face cover 34 can be set in 180mm.Promptly, the thickness of slab that forms the end face 200 of ventilating duct 201 is 2mm, the inside dimension height of ventilating duct 201 is 18mm, heat insulation wall thickness between in the lower surface 202 of ventilating duct 201 and the refrigerator is 25mm, the height of the accommodation space 29a of the superiors is the minimum constructive height 125mm that puts into the tinned drink specification product of 350ml, the dividing plate plate thickness is 10mm, obtains 180mm by such design.Making the thickness of the face that is provided with 28b of the compressor 11 of recess 27 is 20mm, compressor 11 and the gap that face 28b is set with and with the gap of end face cover 34 inner faces respectively be 3mm, the thickness of end face cover 34 is 2mm, on same horizontal plane, the maximum height that then can be housed in the compressor 11 in recess 27 and ventilating duct 201 and the height together is 152mm substantially for the dividing plate bottom 30d that makes the accommodation space 29a of the superiors and the indoor diapire face 30c of recess 27.For accommodating the design of the compressor 11 of the height dimension 144mm of expression in the embodiment 1, corresponding with the maximization of refrigerator, can obtain adapting to the structure that compressor size maximizes and requires.

As mentioned above, can realize between receiving space that compressor 11 is occupied in the refrigerator inboard and the superiors' accommodation space in appearance coordination.Moreover, because generally ease of use is bad, make that comparatively speaking as the especially bad rear space of ease of use among the empty accommodation space 29a of the superiors of accommodation space be that compressor is accommodated recess 27, on the other hand, in more wieldy front space, in the food in being accommodated in refrigerator, can endways arrangement take in common a plurality of tinned drink of once taking in.As a result, the number of taking in of refrigerating chamber integral body increases, and can use the accommodation space 29a of the superiors effectively.

As mentioned above, the ventilating duct 201 be communicated with recess 27 is set makes it end face 200, make the top 203 of compressor 11 be lower than the end face 200 of case body 1, be higher than the lower surface 202 of ventilating duct 201 into case body 1.By this structure, necessary ventilating ducts 201 such as cooling compressor 11 are configured near the end face 200 of the ease of use difference that hand is difficult to contact, therefore, can be except that taking in purposes, effectively utilize end face 200 near, the taking in property in the refrigerator also is improved.In addition, since with the top 203 of compressor 11 be configured in the end face 200 that is lower than case body 1, on lower surface 202 positions that are higher than ventilating duct 201, the highest top 203 of temperature in the cooling compressor 11 effectively, characteristic, the reliability of compressor 11 also are improved.

In addition, in the present embodiment, shown in Fig. 9 A,, also can shown in Fig. 9 B, make the end face cover 34 that forms ventilating duct 201 form the shape that only covers recess 27 upper surfaces though cover the front face side that the end face cover 34 of ventilating duct 201 extends to refrigerator.In this case, owing to suck air from the inlet port 205 that is arranged on ventilating duct 201 front openings portions, cannot see this suction inlet 205 from user's angle, also be in the position that the user can directly not see attached to the dust on the inlet port 205 etc., therefore the appearance design that can improve refrigerator.Especially do not possessing on the top part under the situation of condenser, preferably do not making the end face cover extend to the shape in the place ahead like this.

In addition, for

embodiment

1 and 2 common structure and action effects, do not describe one by one, so long as be applicable to present embodiment, do not produce irrational item, all include identical content.In the present embodiment, the closed container for the compressor of explanation in embodiment 1 and embodiment 2 describes.

As shown in figure 12, possess a plurality of portions 410 of heaving in the bottom of closed container 403.

A plurality of portions 410 of heaving mainly comprise: heave portion and heave portion from the outside of closed container 403 to the concavity that private side forms concave shape to the convex that the outside forms convex form from the inside of closed container.

Near the pin 406 of the compressor that the convex portion of heaving is possessed and the coupling part 420 between the closed container 403, comprise that pin heaves the 410a of portion in closed container 403.It is 420 periphery in the coupling part that this pin is heaved the 410a of portion, heaves portion with the convex that the curvature that is significantly less than closed container periphery curvature forms.

In addition, the support unit 413 of the Machinery Ministry that supporting is made of the electric element and the compressing member of closed container inside comprises support 413a and the spring 414 that is made of elastomeric element.Near the closed container that is positioned at support 413 lower surfaces, possess supporting and heave the 410b of portion.It is periphery in the vertical lower of support that the 410b of portion is heaved in this supporting, heaves portion with the convex that the curvature that is significantly less than closed container periphery curvature forms.

In addition, utilize spot welding fixedly closed container 403 and pin 406 and with the support 413a of the lower side of spring 414.That is, the bottom of pin 406 and support 413 being welded on convex heaves in the portion.

In addition, in closed container, heave portion 411, form, heave the 410b of portion with supporting and be connected to form with the curvature that is significantly less than closed container periphery curvature from the recessed to the inside concavity of the periphery of closed container.

Below, action, effect for the compressor of above structure describe.

Shown in present embodiment, if possess a plurality of portions 410 of heaving in the particularly bottom of closed container 403, purpose for the short transverse miniaturization that makes compressor, upper surface or lower surface at closed container for example are provided with near spherical curved surface from the center of compressor, the Shi Feichang difficulty, the upper surface of closed container or lower surface tend to the curved surface near the plane.

Like this, in the shape of closed container 403, if flat curved surface near planar portions is arranged, then the rigidity of this part dies down, and is easy to be subjected to the influence of noise or vibration.

In the present embodiment, near closed container, possess supporting and heave the 410b of portion as the lower surface of the Machinery Ministry of vibration generation source and the support between the closed container 413.The vibration of Machinery Ministry via spring 414 when closed container transmits, with the bottom of support 413a and the stationary plane of closed container 403 is the center, the 410b of portion is heaved in the supporting that possesses small curve in its vicinity, thus, owing near the rigidity the support bottom is improved, so can reduce vibration, the noise of propagating to closed container from compressor.

Moreover, near the coupling part 420 of the pin 406 of the compressor of the external support of the compressor of side below closed container and closed container 403, possess pin and heave the 410a of portion, thus, can improve near the rigidity the coupling part 420, so can reduce vibration, the noise of propagating to refrigerator body via pin 406 from closed container.

Like this, near the support of the private side of compressor and outer side, possesses the protuberance of heaving shape, thus, for the following side of the overall height that reduces compressor, closed container becomes curved surface near the deep camber on plane, in this case, also can use and improve the particularly compressor of the rigidity of vibration transfer path of closed container, the refrigerator of further reduction vibration, noise is provided.

Moreover, in the present embodiment, form with supporting and heave the 410b of portion and be connected, heave portion 411 to the inboard recessed concavity of closed container, like this, form little concavo-convex of curvature continuously with the shape of complexity, can play the effect that portion's rigidity is heaved in further raising.

In addition, except the vibration transfer path with closed container 403 is the center, possess heaving outside the portion of small curve,, can constitute the pin 106 of compressor and the structure that the contact-making surface 106a between the elastomeric element 107 is positioned at the top position of support unit lower surface 113b as the explanation in enforcement mode 1 and 2.Thus, the vibration of compressor is to the below as the Machinery Ministry of vibration generation source, transmit upward via support unit, then, direction changes upward, rigidity via the bang path of pin 106 when elastomeric element 107 transmits further improves, and makes the bang path complexity therefore can further reduce the vibration of refrigerator.

In addition, except the vibration transfer path with closed container 403 is the center, possess heaving outside the portion of small curve, as implement explanation in the mode 3, depression 281 compressors that are arranged on recess are provided with on the face 280, simultaneously, also elastomeric element 270 can be arranged in the depression 281.By such setting, make the height of elastomeric element 270 be provided with greater than compressor under the situation of the distance between face 280 and the compressor foot 290 at the lift-launch compressor, except reducing from Machinery Ministry to the effect that the vibration of the foot of compressor is transmitted, can also increase elastomeric element, further reduce vibration, the noise of refrigerator.

In addition,, possess outside the portion of heaving 410 of small curve, as shown in figure 14, the stationary plane 456a of pin 456 can be set in the portion of heaving except the vibration transfer path with closed container 403 is the center.At this moment,, also can make the fixed part of foot and closed container be the portion of heaving, can utilize the portion of heaving, realize that the vibration of the vibration transfer path of compressor reduces even under situation about having as the enforcement mode 1 described bend that erects upward from stationary plane.Therefore, even do not have at pin under the situation of the bend that erects upward from the fixed part of itself and closed container, also the contact site 458 of the pin 456 of compressor and elastomeric element 457 can be configured in more position near the center of gravity A of compressor above-below direction.Thus, the vibration amplitude of compressor is minimum near center of gravity A, along with becoming gradually away from center of gravity A vibration around the big center of gravity, the compressor body vibration, so near the vibration amplitude of the pin 456 of center of gravity A and the contact-making surface 458 of elastomeric element 457 lower surface, so can further reduce the vibration of transmitting to refrigerator less than the support unit of supporting machinery portion.

Therefore, can with low cost provide a kind of easy to manufacture, can reduce vibration, not have vibration beastly and produce because the high-quality refrigerator of the noise that vibration causes to the refrigerator transmission.
