Refrigerator

Technical field

The present invention relates to a kind of refrigerator, this refrigerator constitutes by the configuration of the freeze cycle associate device of compressor, condenser, evaporimeter and Defrost water evaporating apparatus etc., seeks effective utilization of the case internal volume of storeroom.

Background technology

In recent years, refrigerator is from the viewpoint of earth environment protection, when more saving the energy progress, seeks that it is easy to use, the raising of taking in property.

In the past this kind of refrigerator, rear area forms the Machine Room in the case outside of the storeroom that is configured in foot, general compressor of in this Machine Room, accommodating freeze cycle, if but such formation, accommodation space at the storeroom of Machine Room foot is reduced and takes in volume by infringement, and the spatial form of accommodation space become the protuberance of removing the Machine Room complexity shape and make that taking in property becomes bad.

Thought that the problem points that solves about such taking in property in the past is a purpose, as the reference spy opens the 2001-99552 communique, following refrigerator is proposed: the recess that mode that the back part according to topmost in the storeroom of body of thermal insulating box descends caves in is set, in this recess, takes in the on high-tension side component parts such as compressor of freeze cycle.

Fig. 9 is the special profile of driving the refrigerator in the past of 2001-99552 communique record of expression.

As shown in Figure 9, body of thermal insulating box 1 has refrigerating chamber 2, refrigerating chamber 3, vegetable compartment 4 in order from last beginning, in the front openings of refrigerating chamber 2 refrigerating chamber rotary door 5 is set.And, consider from the central authorities of body of thermal insulating box 1 to be positioned at the taking in property of the refrigerating chamber 3 of following quadrate part and vegetable compartment 4 and easy to use, be provided with the cold chamber drawer door 6 and the vegetable compartment drawer door 7 of the drawer type that simply takes out.A plurality of accepting racks 8 are set, accommodating container 9a, the 9b of opening shape on refrigerating chamber 3 and vegetable compartment 4 are equipped with in the case of refrigerating chamber 2.This accommodating container 9a, 9b can be supported on track (not diagram), the roller movably along fore-and-aft direction.

Being arranged on recess 10 on the body of thermal insulating box and being mode that the back part according to the topmost of refrigerating chamber 2 descends makes and strides across above the outer container 11 and the position of the end face back part depression at the outer container back side 12.Blocked by the left and right sides wall of body of thermal insulating box 1 about recess 10, its top and back are open, and the opening portion of this recess 10 covers by recess lid 15, and this recess lid 15 is to be made of 13 lids 15 of upper plate and roughly rectangular therewith backboard 14.And recess lid 15 can be fixed on the body of thermal insulating box 1 by screw with dismantling.

Together dispose with Machine Room fan 18 as the compressor 16 of freeze cycle constitution equipment and condenser 17 and to be housed in the recess 10, by recess lid 15 coverings that constitute by upper plate 13 and backboard 14.

And the back part of the refrigerating chamber 3 that is configured in the body of thermal insulating box stage casing together as the evaporimeter 20 and the fan 21 of freeze cycle constitution equipment, constitute dark depth as the vegetable compartment 4 of the storeroom of foot.

Thus, with take in compressor 16 in the lower backside of body of thermal insulating box 1, condenser 17 is compared, internal volume as the vegetable compartment 4 of the storeroom of foot can be become big, formation with deepening, also can make the spatial form of storeroom not become the shape of the complexity that the idle space by compressor 16 grades causes, improve taking in property.

About refrigerator as constituted above, the following describes its action, effect.

At first, action is illustrated about freeze cycle.According to the temperature of the setting in the case by moving from the signal freeze cycle of control substrate (not have diagram) and carrying out cold air and move.By the action of compressor 63, the cold-producing medium of the HTHP of discharge is at condenser 83 heat releases and condensation liquefaction, and when carrying out heat exchange with capillary (not having diagram) by being depressurized the liquid refrigerant that becomes low-temp low-pressure, arrive evaporimeter 76.

Action by cooling fan 77, carry out heat exchange with the air in each storeroom, cold-producing medium carburation by evaporation in the cooler 76 because supply with the cold air of control low temperature by cold air throttle setting etc., can cool off in the mode of the temperature of the regulation of the setting of keeping each storeroom.The cold-producing medium that is come out by evaporimeter 76 is drawn into compressor 63 by suction line.

Compressor 63 is positioned on the 2nd top 61 of body of thermal insulating box 50 and is not configured in the rear area of the 2nd refrigerating chamber 54, cooling chamber 70 is configured in the back side of the 2nd refrigerating chamber and vegetable compartment 55, evaporimeter 76 and fan 77 are provided with in the altitude range of general the 2nd refrigerating chamber 54 and vegetable compartment 55, by shortening the depth size, this depth size makes evaporimeter 76 prolong along short transverse, and the thickness attenuation of cooling chamber 70 can be reduced as the case internal volume not have the idle space contributed.

And, the case in the place ahead, bottom surface of body of thermal insulating box 50 outside is full duration ground reduced height size and condenser 83 is installed almost, near and reduced height size the 2nd recess 82 and evaporating dish 84 is installed, thus, can reduce the height of the 2nd recess 82 and reduce the idle space that does not have contribution as the case internal volume, the height of the 2nd recess 82 is the ground that is set up and the space between the 1st bottom surface sections 80 and to the space of the 2nd bottom surface sections 81.

As mentioned above, be difficult to arrive at the end face rear of body of thermal insulating box 50 and rear, bottom surface this class user's hand, we can say near upper and lower settings the

1st recess

62,82 of the body of thermal insulating box 50 in the space that idle space is, there are not compressor 63, the condenser 83 of contribution, the needed parts of freeze cycle of evaporimeter 84 these classes to be housed in the little space to the case internal volume, can increase the volume of taking in of the easy-to-use height and position of user, improve taking in property.

In the storeroom configuration of present embodiment, the top of body of thermal insulating box 50 is made as refrigerating chamber 51, the storeroom of just going up of hypomere is made as vegetable compartment 55, the storeroom that is clipped between refrigerating chamber 51 and the vegetable compartment 55 is made as ice-making compartment the 52, the 1st refrigerating chamber 53 respectively, thus, refrigeration, the whole temperature band freezing, vegetables as the basic function of refrigerator can be concentrated at above-mentioned user's easy-to-use position.

Especially, in recent years, simple from user's frequency of utilization or freshness management, the viewpoint easy to use of ergonomics etc. is set out, the refrigerating chamber 51 that frequency of utilization is the highest is located at the open-and-shut above last fragment position of waist that can access in user's front, the discrepancy of weight thing, the vegetable compartment 55 of healthy ambition is located at easy-to-use stage casing, and, the standby of long-time not access etc., and there is the refrigerating chamber of when access, falling the first-class worry necessity in ground to be located at hypomere, though the refrigerator according to above-mentioned design becomes main flow, but in this design, owing to comprise the configuration of the Machine Room of compressor 63, the shortcoming that the capacity of taking in of the refrigerating chamber 54 that can not fully guarantee hypomere is arranged, and in the present embodiment, the depth and the vegetable compartment 55 of the 2nd refrigerating chamber 54 of hypomere similarly can be enlarged, and when summer the frequency of utilization height, to worry that ice-making compartment 52 that taste shifts is made as independently the chamber and is arranged on roughly position intermediate of refrigerator, thus, and then can provide easy to use and take in the refrigerator that efficient has improved.

In a plurality of of the projecting height refrigerating chamber of the case inboard of the 1st recess 62 at the end face rear that is arranged on body of thermal insulating box 50, not constitute to the outstanding mode in the below of the frame that is positioned at the extreme higher position, thus, the depth that only is used to take in the minimum epimere of frequency of utilization is diminished, the volume of taking in of epimere below becomes big, finishes the design that looking when opening refrigerating-chamber door 31a do not have the smoothness of constriction.

The configuration that the bottom surface sections case of body of thermal insulating box 50 is outer, by condenser 83 is configured in the place ahead, evaporating dish 84 is configured in the rear the 2nd recess 82 around, heating installation by condenser 83 heat exchanges causes ascending air, so in the superjacent air space of evaporating dish 84, cause convection current, thereby can improve the evaporation of water ability.In addition, even evaporating dish 84 condenser 83 configuration in the wings forwardly, because cause because the convection current evaporability in the space of heat release can similarly obtain effect.And then, by at the 2nd recess 82 towards back side direction and make the configuration of the heat release fan 86 of convection current, can improve the heat release ability of the condenser 83 that is configured in periphery, improve the ability that makes the water evaporation that is trapped in evaporating dish 84, can make both more miniaturizations.

And by evaporating dish pipeline 87 is set, this evaporating dish pipeline 87 makes the cold-producing medium circulation of the HTHP that is compressed by compressor 63 in evaporating dish 84, can improve the ability that makes Defrost water evaporating, can make evaporating dish 84 further miniaturizations.In addition, be arranged on recess lid 62a, the 82a of the

1st recess

62,82 up and down, the effect that can improve behind the opening that heat release, heat extraction use separately is being set.

And, the 2nd recess 82 of the bottom surface of body of thermal insulating box 50 also has following effects: take in evaporimeter 84 and condenser 83, in addition, raising is as the operation of the installation of the space of drainpipe 89, condenser 83, this drainpipe is used for the water by pharoid 78 defrostings is delivered to evaporating dish 84, also improves the taking-up operation of evaporating dish 84.

Because refrigerating chamber 51 frequency of utilization in refrigerator is very high, by the refrigerating-chamber door 31a of rotary type, can make collecting article spread all over the position of user's sight line under the state in inspection box, therefore optimize accessibility.

Near the central authorities of the short transverse by ice-making compartment 52 being configured in body of thermal insulating box 50, when can not bend over to take out ice simply, can prevent to move by being made as chamber independently from other the smell of chamber, further, because ice-making compartment door 52a individually is set, suppress because the intrusion of the outer gas of door switch also is associated with the energy.And when high summer of frequency of utilization owing to need a large amount of ice, by making air channel (not diagram), the miniaturization of cold air air door, this air channel constitutes the 1st refrigerating chamber pipeline 100 at the back side that is positioned at ice-making compartment 52, can make the depth of cooling chamber 70 become littler, the depth that can further prolong the ice-making compartment container 96 of storage of water this moment increases pondage.

The laterally configuration side by side of the 1st refrigerating chamber 53 and ice-making compartment 52, preserve as freezing, short-term, in order to make food freezing faster, because need be with the shape attenuation of the food taken in, the height dimension of the 2nd refrigerating chamber 54 is made as littler, opposite to the height change of the 2nd refrigerating chamber is big, the advantage of taking in raw materials such as frozen food is greatly arranged capacity.Further, have the storeroom that can switch the function from refrigerated storage temperature to cryogenic temperature by the 1st refrigerating chamber 53 is made as, the function of the variation by paying life style that can corresponding user can improve value.And, the same with ice-making compartment 52, by making air channel (not diagram), the miniaturization of cold air air door that constitutes the 1st refrigerating chamber pipeline 100, can make the depth of cooling chamber 70 become littler, can further prolong the depth of the 1st refrigerating chamber container (not having diagram) of easy-to-use height and position this moment, increase and take in volume.

Because vegetable compartment 55 is near the central authorities of the short transverse of body of thermal insulating box 50, and be configured in the bottom of ice-making compartment 52 and the 1st refrigerating chamber 53, diminish as the cost of the taking-up of the beverage product of the greengrocery of weight thing etc., pet bottle etc., thereby improve accessibility greatly.

And, also passable even the 2nd refrigerating chamber 54, vegetable compartment 55 are not the storerooms of drawer type, if but its effectiveness of the storeroom of drawer type is bigger.Promptly, enlarge the amount of the depth of the 2nd refrigerating chamber 54, vegetable compartment 55, the selected amount of pulling out that can enlarge refrigerating chamber accommodating container 105, vegetable compartment accommodating container 106 by roller, when the user can observe in the accommodating container largo, carry out the access of high efficiency collecting article, can reduce and forget use and carry out the management of health.For selecting of roller, can use high and high-quality bearing-type roller or the middle roller of sliding, if adopt such roller that can increase the type of the amount of pulling out outside case, then can enjoy its effect more.

And, with case inner bottom surface portion area much at one cooling chamber 70 is set on the perspective plane of short transverse with the 2nd recess 82, therefore the width and the overhang in the case of the 2nd recess 82 of cooling chamber 70 are roughly the same, the refrigerating chamber accommodating container can be cubical shape the time, can enlarge depth and improve and take in efficient.And, since case inner bottom surface portion just above evaporimeter 76 is set, can use as the part when evaporating dish 84 is carried the frost of evaporimeter 76, and then as if case inner bottom surface portion being made as the white receiver of evaporimeter 76 and forming, can cut down the parts of the dew receiver of general use, thereby increase the cost flexibility.

In addition, in the present embodiment, the vegetable compartment 55 of drawer type is located at top, the 2nd refrigerating chamber 54 is located at foot, but is located at top, vegetable compartment 55 is located at foot can obtains same effect with the 2nd refrigerating chamber 54 that disposes in contrast to this drawer type.
