Description

refrigerator Field of invention

The present invention relates to a refrigerator.

Background of the invention

In recent years, the premium bottle of beverages has become more popular, and the variety has been diversified from daily drinkers such as tea, water, sports drinks, etc., and has changed the preferences and habits of users. . Therefore, the beverage products stored in the refrigerator have also increased the types and the amount of ice stored, and there has been a demand for improvement in storage and storage. Further, the beverages may be leaked substantially if they are placed horizontally, and in view of convenience of use, it is also preferable to use a vertical storage which can be quickly taken out and returned to the original state.

Furthermore, the popularity of high-airtight and high-insulation houses such as buildings has also reduced the number of low-temperature and low-humidity storage places in the home, that is, the so-called "shady places." Therefore, the preservation conditions of seasonings such as soy sauce and rice are not good, and families are dissatisfied with the reduction in quality. As a result, there are also users who store seasonings and rice in a refrigerator or intend to use a refrigerator for storage.

Therefore, there has been proposed a refrigerator in which a compartment is provided with a partial storage of a PET bottle using the internal volume of the fruit and vegetable compartment of the refrigerator (see, for example, Patent Document 1).

Further, in the refrigerator, a pipe such as a compressor, an evaporator, or a condenser is connected in a ring shape, and a cooling cycle in which a refrigerant is sealed inside the pipe is provided, and the air inside the heat insulating box can be cooled by the evaporator to realize freezing. And cryogenic storage space such as refrigeration. Therefore, the condensation and frost can be saturated by the moisture in the cooling air, and the condensed water can be discharged out of the tank by periodic defrosting or the like.

Heretofore, in order to completely treat the condensed water in the refrigerator body, condensed water is accumulated in a thin disk-shaped member called an evaporating dish disposed under the refrigerator, and is heated by the lower portion of the evaporating dish to evaporate. Further, the air blown from the fan for cooling the compressor is used to promote the evaporation of the condensed water from the evaporating dish (see, for example, Patent Document 1).

Figure 31 is a cross-sectional view of a conventional refrigerator, and Figure 32 is a cross-sectional view of a vegetable and fruit compartment storage container of a conventional refrigerator.

As shown in Fig. 31, the heat insulating box 1 is composed of the refrigerator compartment 2, the vegetable compartment 3, and the freezing compartment 4 in order from the top. The cooling cycle in the coolable tank is provided by a compressor 6, a condenser (not shown), a pressure reducer (not shown), and a pressure reducer (not shown) provided in the machine room 5 disposed at the bottom of the back surface of the heat insulating box 1. The evaporator 7 on the back side of the tank is connected in a ring shape, and is sealed with a refrigerant or a refrigerating machine oil inside the piping.

Further, a fan 8 is disposed in the vicinity of the evaporator 7 in the tank, and the air in each chamber is circulated and exchanged with the low-temperature evaporator 7 to be cooled. The evaporator 7 can condense and frost the moisture in the saturated air during heat exchange. In order to prevent the frost from obstructing the circulation of the air, the defrosting heater (not shown) periodically performs defrosting, and the defrosting water flows through a drain pipe (not shown) toward the bottom surface of the heat insulating box 1 The disc-shaped evaporating dish 9 is discharged.

The evaporating dish 9 contains a heating mechanism 10 that uses a portion of the condenser below and utilizes residual heat to promote evaporation of the condensed water.

Moreover, as shown in Fig. 32, the vegetable compartment 3 is composed of the first storage container 11 and the second storage container 12 disposed at the upper portion thereof, and basically constitutes three storage compartments. The first storage space 13 having the longitudinally long upper front portion, the second storage space 14 inside the second storage container 12, and the third storage container 12 corresponding to the inside of the first storage space 13 are provided. Storage space 15.

The first storage space 13 can mainly accommodate beverages such as large-sized PET bottles of 1.5 liters to 2 liters and 1 liter paper trays, and can also store vegetables to be stored upright. In addition, the second storage space 14 is mainly used for storing fruits and small vegetables, and the third storage space 15 is mainly used for storing large vegetables such as cabbage and Korean cabbage.

In addition, there is a proposal for a method for improving the storage efficiency of the vegetable and fruit compartments 3, and the upper container is formed into a shallow shape having different heights from left to right, and the heights of the upper and lower storage spaces are divided into two sizes (see, for example, Patent Document 2).

Fig. 33 is a front view showing the vegetable and fruit compartment of the conventional refrigerator disclosed in Patent Document 2. As shown in Fig. 33, the vegetable compartment 33 includes the first storage container 16 and the second storage container 17 having the bottom surfaces having different left and right heights, and the heights of the second storage space 18 and the third storage space 19 in the left-right direction are divided. Two kinds of shapes form a deep and shallow shape.

Here, the second storage space 18 is composed of a space B having a depth of 85 mm and a space C having a depth of 115 mm. Further, the third storage space 19 is composed of a space D having a depth of 145 mm and a space E having a depth of 175 mm.

In the setting of the height dimension of the storage item, the second storage space 18 is set to accommodate 115 mm (space C) of a large fruit such as grapefruit, and the third storage space 19 is set to accommodate large vegetables such as 175 mm (space E) of 2L-sized Korean cabbage. The large-sized object storage space (the space C and the space E) is set to be different from each other and is high or low, so that the height of the vegetable compartment 33 can be controlled to 260 mm, and the height of the fruit and vegetable compartment in the overall height dimension of the refrigerator can be suppressed.

The storage capacity of the refrigerator can be reduced in size by miniaturization of the heat insulating wall, cooling cycle, and miniaturization of the air duct, and the size is gradually increased without greatly changing the outer dimensions.

Moreover, the internal arrangement of the refrigerator was examined from the viewpoint of ease of use, and the upper revolving door type refrigerating compartment and the lower drawer type of vegetable and fruit compartment and freezing compartment were provided in plural layers. Especially in the large-capacity large-sized refrigerator, the 5-door to 6-door structure of the drawer type 3 has become the mainstream in recent years.

Among the large-scale trend of the storage volume, especially the height of the refrigerator is also designed to be approximately 1800 mm. Further, in the above-described internal arrangement, the drawer chamber is used from the viewpoint of ease of use of the drawer chamber, convenience of the food in the refrigerator compartment, and ease of use of the gantry provided on the revolving door of the refrigerating compartment. The upper part is designed to be less than 1000 mm from the ground. Further, in the case of a person having a lower height, it is also preferable to control the height of the uppermost drawer to a height of 900 mm to 930 mm or less.

As described above, since the upper limit height of the drawer chamber is limited, it is an important subject to set the height ratio of the drawer chamber of the three layers. That is, any of the storage capacity and the height dimension of the freezing compartment, the vegetable and fruit compartment, and the ice making compartment may be increased, and any other potential will be reduced, which is a problem.

The amount of the contents of the refrigerator is changed from time to time, and the trend in recent years is expected to increase the capacity of the freezer compartment due to the expansion of the frozen food market. Secondly, the fruit and vegetable room is expected to increase the storage capacity and storage height of 1.5-liter to 2-liter PET bottles, 1 liter carton beverages, bottles and cans, and more than vegetable storage capacity.

If the storage height of the vegetable and fruit room is designed according to the 1.5-liter premium bottle, the storage height of the whole fruit and vegetable room will increase, and the storage capacity of the vegetable and fruit room will be increased, so the storage capacity of other drawers such as the freezer will be Relatively reduced. Specifically, the height of the first storage section on the front side must be about 310 mm for the height of the 1.5-liter liter bottle, the height of the second storage space on the upper layer is 115 mm for the large fruit, and the height of the third storage space at the lower portion is 175 mm. , the total will be 290 mm in height. The difference between the front side and the inside of the vegetable and fruit room is 20 mm. If the depth of the left and right heights is different, the difference will increase.

Further, the conventional refrigerator is provided with a thin disk-shaped evaporating dish at the bottom portion, and a condenser for promoting evaporation at the lower portion of the evaporating dish, so that the usable range of the storage volume of the drawer chamber is also limited from the bottom. Therefore, there is a problem that the storage volume of the drawer chamber is not ensured to the maximum.

Moreover, the conventional refrigerator also has a condenser on the bottom surface or a substrate for controlling the refrigerator. That is, the usable range of the storage volume of the drawer chamber is generally limited by the evaporating dish, the condenser, the substrate, and the like of the functional parts used outside the refrigerator box, and thus the storage volume of the drawer chamber is not ensured to the maximum. problem.

Of course, increasing the size of the refrigerator to ensure the storage volume, but the size of the external size will result in the use of materials and important increases, not in line with resource conservation standards, and production costs will increase, transport and storage will also expand Energy consumption.

The best form for implementing the invention

In the following, the embodiments of the present invention are described with reference to the accompanying drawings, but the same reference numerals are used for the same reference numerals as those of the prior art or the previously described embodiments, and the detailed description thereof is omitted. Further, the present invention is not limited to the following embodiments.

(First embodiment)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of a refrigerator according to a first embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a front view showing a refrigerator according to a first embodiment of the present invention. As shown in Fig. 1, the refrigerator 100 is provided with a left and right split door panel at the upper portion, and is provided with a plurality of heat insulating boxes 101 which are insulated from the inside and the outside of the refrigerator 100. Storage room. Further, in the following embodiments of the present invention, as shown in Fig. 1, the refrigerator is viewed from the front side with the left and right sides of the paper as the width direction, and the direction through the paper surface as the depth direction, and the paper surface as the height direction. direction.

The storage compartment which has been divided into a plurality of refrigerators 100 has different functions (cooling temperature), and can be divided into a refrigerating compartment 102, an ice making compartment 105, a switching compartment 106 which can change the temperature inside the compartment, a vegetable compartment 103 and a freezing compartment. 104 and so on.

The front surface of the refrigerator compartment 102 located at the uppermost portion of the refrigerator 100 is provided with a rotary heat insulating door 107 which is foamed and filled with a heat insulating material such as polyurethane, and a box-shaped storage space is formed in the box.

Further, the ice making compartment 105, the switching compartment 106, the vegetable and fruit compartment 103, and the freezing compartment 104 disposed below the refrigerating compartment 102 are drawer-type storage spaces. Next, each of the drawers is provided with a heat insulating door 108, whereby the storage room can be taken out and sealed to be freely opened and closed to avoid leakage of cold air.

The heat insulating box 101 is formed by filling a heat insulating material such as a rigid foamed polyurethane between a metal case and a resin inner case, and is a box having a substantially rectangular parallelepiped opening at least one side. The heat insulating box 101 has a function of blocking heat energy flowing into the heat insulating box 101 from the external environment (atmosphere).

The refrigerating compartment 102 is capable of maintaining a storage compartment at a lower temperature to the extent that it is refrigerated and stored without causing the storage to be frozen. Specifically, the lower temperature limit of the refrigerating compartment 102 is usually set in the range of 1 ° C to 5 ° C.

The vegetable and fruit chamber 103 is disposed at the lowermost portion of the heat insulating box 101, and is mainly for the purpose of refrigerating vegetables, and is maintained at a lower temperature to such an extent that the contents are not frozen. Further, the vegetable and fruit compartment 103 is set to have a temperature equal to or slightly higher than that of the refrigerating compartment 102. The lower temperature limit of the specific vegetable and fruit compartment 103 is set in the range of 2 ° C to 7 ° C. In addition, the low temperature that does not freeze can maintain the freshness of leafy vegetables for a long time.

The freezer compartment 104 is set in a storage compartment of the freezing temperature zone. Specifically, the freezing compartment 104 is usually set to be in the range of -22 ° C to -18 ° C for cryopreservation, but may be set to a low temperature such as -30 ° C or -25 ° C in order to improve the frozen storage state.

The ice making compartment 105 is provided with an ice maker (not shown) in the box, and an ice machine can be used to make ice cubes, and the storage compartment of the ice cubes can be stored. The set temperature of the ice making compartment 105 is substantially the same as that of the freezing compartment 104, but it can also be set to be in the range of, for example, -12 ° C to -18 ° C, in order to save energy and increase the temperature so as not to melt the ice.

The switching chamber 106 can be switched between the cooling rate band and the freezing temperature zone by the operating panel mounted on the refrigerator 100 depending on the application.

In addition, the left and right opposite doors provided in the refrigerating compartment 102 can reduce the space required for opening and closing the door in the narrow kitchen space, and the moving lines in either direction can not be used for convenience. Therefore, although the right and left opening doors have been adopted in recent years, compared with the single door form, there is still a disadvantage that the storage capacity of the gantry is small. In other words, the amount of the beverage such as the large-sized bottle is small, and there is a shortage in the storage property. In order to solve the above problem, a space for vertically storing a PET bottle or the like is provided in a part of the vegetable and fruit compartment 103.

Moreover, the total height of the refrigerator 100 is usually set to about 1800 mm, and if it is larger than this size, the handling of the refrigerator and the obstruction during transportation are increased. The uppermost height of the lower drawer chamber is about 920 from the viewpoint of ease of use of the drawer chamber, convenience of food collection in the refrigerating compartment 102, and ease of use of the gantry provided on the heat insulating door 107 of the refrigerating compartment 102. Millimeter.

Further, the upper portion of the drawer of the vegetable and fruit chamber 103 is about 400 mm from the ground, the upper portion of the drawer of the freezing chamber 104 is about 750 mm, and the opening front edges of the freezing chamber 104 and the vegetable and fruit chamber 103 are each set to about 310 mm and about 335 mm.

Fig. 2 is a perspective view showing the back side of the refrigerator. As shown in FIG. 2, the top surface portion of the refrigerator 100 is formed with a concave portion which is formed in a downward direction toward the back surface of the refrigerator 100, and a machine room 201 is formed in the concave portion. In addition, in general, the machine room 201 is covered by the outer casing 202 in order to keep silent and protect internal parts.

Fig. 3 is a perspective view showing the upper back surface of the refrigerator in the open state of the refrigerator according to the first embodiment of the present invention. As shown in Fig. 3, the machine room 201 is mainly a space for accommodating components constituting the high pressure side of the cooling cycle, in addition to the compressor 203 and the fan 211 for cooling the compressor 203. The machine room 201 is in a state of extending into the upper rear area of the outside of the heat insulating box 101.

Here, the mechanical chamber 201 is disposed at the uppermost portion of the refrigerator 100, and the vegetable and fruit chamber can be particularly improved compared with the refrigerator in which the compressor 203 is disposed in the rear of the storage compartment which is conventionally known as the lowermost portion of the heat insulating box 101. The capacity of the lowest storage room such as 103. Further, since the ineffective space in which the uppermost hand portion of the refrigerating chamber 102 cannot be extended can be used as the machine room 201, it is effectively disposed from the viewpoint of ease of use, and the actual storage volume of the refrigerator 100 can be improved. In particular, when the lower portion constitutes the drawer type, the storage space in the depth direction can be pulled out and used, which is more effective.

The cooling cycle is connected in a ring shape by a compressor 203, a condenser (not shown), a dryer 251 for removing moisture, a capillary 252 as a pressure reducer, an evaporator (not shown), and a suction pipe 253. It is sealed with a refrigerant that can heat the inside of the piping, and a refrigerating machine oil that can be lubricated and insulated. The suction pipe 253 and the capillary tube 252 are connected by means such as soldering, and the heat transfer can be performed inside the cooling cycle for the purpose of cooling cycle efficiency.

Further, the condenser is connected to the compressor 203 via the discharge pipe 254, and the heat release pipe portion which can be attached to the outer peripheral portion of the heat insulating box 101 to be heat-exchanged, and the condenser 211 is forcibly cooled, and the condenser is provided to the fan 211. Inside the wind tunnel. The discharge pipe 254 is formed in a large spiral shape to secure the heat exchange length required for the fan 211.

Further, the refrigerant uses R600a having a relatively small warming coefficient corresponding to the environment, and the refrigerating machine oil uses a mineral oil having a high compatibility.

The compressor 203 is a device for compressing a refrigerant, and adopts a reciprocating compression method, and further adopts a variable frequency control capable of performing low-energy operation when the load is small. The lower part of the compressor 203 is provided with four leg bodies 231 protruding outwardly (one of which is not shown), and the leg body 231 can be engaged with the tip nails integrally provided on the bottom plate 204, and placed on the anti-vibration rubber. 205 is mounted on the machine room 201.

Further, the periphery of the anti-vibration rubber 205 is protruded upward from the bottom plate 204, and a cylindrical support wall 244 is integrally provided. When the refrigerator 100 is fallen down, it is dispersed to receive the impact transmitted from the compressor 203 to the tip nail to prevent the tip nail from being damaged.

In addition, a stud 206 is mounted on the front end of the tip nail to prevent the foot body 231 from coming off the tip nail.

Further, since the fan 211 is disposed on the suction pipe 253 side of the compressor 203, and the components are not disposed on the discharge pipe 254 side, it is possible to fundamentally solve the problem that the discharge pipe 254 having a large vibration interferes with other parts and the like.

Further, since the discharge pipe 254 can be extended in the spiral shape in the duct of the machine room 201, the heat radiation capability can be improved.

Further, the wind direction of the fan 211 flows in the direction of the fan 211, the compressor 203, and the discharge pipe 254 in this order from the suction pipe 253 side. Thereby, the lower temperature fresh air can be caused to flow to the compressor 203 to suppress the temperature rise and improve the reliability. In particular, by sucking air from the opposite side of the discharge pipe 254, the temperature rise due to the heat release of the discharge pipe 254 itself and the temperature of the left side wall surface 255 of the tank connected to the discharge pipe 254 can be suppressed.

Fig. 4 is a perspective view showing the lower side of the refrigerator in the first embodiment of the present invention. As shown in Fig. 4, an evaporating dish 301 is attached to the outer bottom surface of the heat insulating box 101 at the bottom of the refrigerator 100. Further, the back surface of the evaporating dish 301 is provided with a recessed door handle 311 integrally with the evaporating dish 301.

The door handle 311 is a portion that can be held while being transported in a state where the back surface of the refrigerator 100 is lowered downward, and is integrally provided with the evaporating dish 301. Therefore, if the evaporating dish 301 is attached to the refrigerator 100, the refrigerator 100 will be provided with the door handle 311, and the number of parts can be reduced, and the manufacturing steps can be simplified, and the manufacturing of the refrigerator can be simplified as compared with when the door handle is directly attached to the heat insulating box 101. Simplified.

Further, since the door handle 311 is not embedded in the heat insulating box 101, the polyurethane foaming fluidity is not impeded, and the heat insulating material can be filled stably.

A recess 350 is continuously provided in the vertical direction on the side of the space 305. Next, the convex portion 403 of FIG. 7 is fitted to the concave portion 350, and the pouring prevention portion 400 can be fixed to the partition portion 308.

The dump preventing portion 400 and the partition portion 308 can be simply processed to fix the tilt preventing portion 400 at a predetermined position without newly providing other parts for fixing the dump preventing portion 400.

Further, the concave portion 350 and the convex portion 403 are each tapered downward from the upper side to reduce the width.

Further, four recesses 350 are formed at predetermined intervals in the width direction of the partition portion 308. The term "predetermined interval" as used herein refers to a length slightly larger than the width of the contents, such as a length slightly larger than the width of the bottle. Thereby, the position of the fixed dumping prevention part 400 can be arbitrarily determined according to the size and quantity of a storage object. As a result, the arrangement space of the storage items in the first storage space 305 can be flexibly changed. Therefore, the degree of freedom in the arrangement space can be improved, and the usability in the first storage space 305 can be improved.

Next, a state in which the stored objects are stored in the first storage space 305 in the first storage container 303 will be described.

FIG. 9 is a view showing an essential part of the upper side in a state in which the storage items of the first storage container of the refrigerator according to the first embodiment of the present invention are stored. The ninth figure is a state in which the first recessed portion 350 (not shown) from the right is fixed to the tilt preventing portion 400.

As shown in Fig. 9, the space in which the dumping prevention unit 400 provided in the first storage space 305 is separated is provided for storing the 2 liter bet bottle 501 and the soy sauce seasoning bottle 502. Next, by dumping the preventing portion 400, it is possible to prevent the pouring of the 2 liter bottle 501 and the seasoning bottle 502 of the soy sauce.

In addition, in Fig. 9, although the 2 liter bottle 501 and the soy sauce seasoning bottle 502 are housed, a 2 liter bottle can be accommodated instead of the soy sauce seasoning bottle 502, that is, the space that has been separated is also Two bottles of 2 liter PET bottles can be placed.

Fig. 10 is a view showing an essential part of the upper side in a state in which other storage items in the first storage container of the refrigerator according to the first embodiment of the present invention are stored. Fig. 10 is a view showing a state in which the tilt preventing portion 400 is fixed to the second concave portion 350 (not shown) from the right.

As shown in Fig. 10, the space in which the dumping prevention unit 400 provided in the first storage space 305 is partitioned can accommodate four bottles of soy sauce seasoning bottle 502, and the dumping prevention unit 400 can prevent the soy sauce seasoning bottle 502. Dumped. Moreover, the storage items of the same type can be arranged in one space, and the first storage space 305 is also easy to use, and the arrangement is neat and beautiful.

Further, in the first embodiment of the present invention, as shown in Figs. 9 and 10, the front end portion of the flat portion 401 of the tilt preventing portion 400 is not fixed to the free end 401a of the first storage container 303. Therefore, the front end portion of the flat portion 401 has elasticity, and even if the storage contents such as the bottle can be tilted, the impact force can be alleviated and the impact sound can be reduced.

Further, in the first embodiment of the present invention, the material of the pouring prevention portion 401 is made of polypropylene (PP) and is more elastic. Therefore, even if the storage contents such as the bottle can be tilted, the impact force can be alleviated and the impact sound can be reduced.

Further, in the first embodiment of the present invention, as shown in Fig. 6, the tilt preventing portion 400 is provided with a reinforcing portion 404 near the boundary portion between the fixed portion 402 and the flat portion 401. Thereby, the strength of the vicinity of the root of the tilt preventing portion 400 which is likely to cause stress concentration after the storage object is poured can be improved.

On the other hand, the reinforcing portion 404 provided near the boundary portion between the fixing portion 402 and the flat portion 401 is not provided in the vicinity of the free end 401a of the front end portion of the tilt preventing portion 400. Therefore, the end portion of the flat portion 401 has elasticity, and even if the storage contents such as the bottle can be tilted, the impact force can be alleviated and the impact sound can be reduced. In other words, the tilt preventing portion 400 is provided with a reinforcing portion 404 near the root portion to increase the strength, and the reinforcing portion 404 provided near the root portion is not provided near the front end portion to have elasticity.

Further, in the first embodiment of the present invention, as shown in Fig. 9, the depth Y of the depth of the tilt preventing portion 400 is preferably Y (3/4) when the depth of the first housing space 305 is Z. Z.

In this way, when the second storage space 305 is placed in two rows of the PET bottle in the depth direction, the free end 401a can be positioned on the front side of the center line of the front side of the bottle, so that the stored article can be stored more securely.

Further, in the first embodiment of the present invention, the dump preventing portion 400 is provided for one single partition portion 308, but two or more may be provided.

By dividing the arrangement space in the first storage space 305, the arrangement space of the three kinds of storage items such as a large bottle such as a bottle, a bottle, and a cabbage can be divided into various types, thereby improving the use of the first storage space 305. Convenience.

Further, in the first embodiment of the present invention, the tilt preventing portion 400 and the partition portion 308 are separate components, and the partition portion 308 can be attached or detached. However, the tilt preventing portion 400 may be integrally formed, for example, by the partition portion 308. The partition 308 is fixed. Further, the front end portion of the pouring prevention portion 400 and the front side of the first storage container 303 may be connected to the front side of the first storage container 303 in a bridge shape.

In this way, when the second storage space 305 accommodates a heavy storage such as a large liter bottle such as a liter bottle, a can, or a cabbage, the strength of the bottom surface of the first storage space 305 can be increased. Therefore, it is possible to suppress the bending deformation of the first storage container 303 when the food is stored, and to reduce the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103.

Moreover, by pre-dividing (blocking) into a narrow space and a wide space, it is possible to receive nano-grain in a narrow space, and to accommodate a 2-liter PET bottle in a wide space. It is easier to distinguish the storage items.

Further, therefore, the dump preventing portion 400 is integrally formed with the heat insulating door 108, so that the number of parts as the dump preventing portion 400 is not increased.

Fig. 11 is a perspective view showing the evaporating dish of the refrigerator in the first embodiment of the present invention. As shown in Fig. 11, the evaporating dish 301 can store a condensed water generated by a cooling cycle, particularly an evaporator (not shown), and forcibly evaporates the condensed water, which includes a mounting portion 312, a wall portion 313, and ribs 314. The bottom plate portion 315. Further, the refrigerator 100 includes a fan 324 as a blowing device and a heating device 325 which is a part of a condenser pipe using a cooling cycle as a component of the evaporating dish 301.

Further, as shown in Figs. 5 and 11, a space 327 is further provided behind the step space, and the space 327 is provided with a fan 324 which is capable of forcibly convecting the air to the evaporating dish 301 to promote evaporation of the condensed water on the evaporating dish 301. . Here, the evaporating dish 301 is extended to a space 327 in which the fan 324 is disposed.

The mounting portion 312 is for mounting a frame-shaped member of the fan 324 to the evaporating dish 301, and is integrally formed with the evaporating dish 301. Thereby, even when the fan 324 is individually attached to the plurality of evaporating dishes 301, the positional relationship between the evaporating dish 301 and the fan 324 can be kept stable, and the evaporating dish 301 can be blown at a desired position.

The wall portion 313 is integrally provided on a portion of the periphery of the evaporating dish 301, and has a function of blocking condensed water and preventing the condensed water from overflowing from the evaporating dish 301.

The rib 314 has a function of storing condensed water, and is integrally protruded from a thin plate-like member of the evaporating dish 301. Further, the height of the rib 314 is set to be lower than the height of the wall portion 313.

In the first embodiment of the present invention, the rib 314 is disposed in a state in which the wall portion 313 disposed on the inner side extends in the depth direction to the wall portion 313 disposed on the front side, and the rib 314 is disposed in the middle portion in the width direction of the evaporating dish 301. There are 2 in parallel. Moreover, when the evaporating dish 301 is attached to the refrigerator 100, the rib 314 is disposed, and the condensed water discharged from the liquid discharge pipe 323 of FIG. 5 can be introduced between the two ribs 314.

Thereby, the condensed water of the evaporation object is stored in the area surrounded by the two ribs 314 and the wall portion 313. The above-mentioned field is the field of receiving the strongest air supply from the fan 324, and is also the field in which the heating device 325 is disposed. Therefore, the condensed water stored in the above field can be efficiently evaporated.

Further, when the amount of condensed water is particularly large, even if the condensed water overflows beyond the rib 314, the height of the wall portion 313 disposed outside the rib 314 is larger than the rib 314, so that the overflowed condensed water can be blocked by the wall portion 313. As described above, the condensed water can be prevented from overflowing the outside of the refrigerator 100 by the evaporating dish 301.

Moreover, although the evaporating dish 301 is provided with the door handle 311, the evaporating dish 301 is provided with the rib 314 to strengthen the structural strength of the evaporating dish 301, so that even if the door handle 311 is held by the handle 311, the refrigerator 100 can be fully supported. Load.

The bottom plate portion 315 forms a partial plate-like portion of the bottom portion of the evaporating dish 301, and is disposed such that its predetermined position is at the lowest lowest portion 316 to form an inclined state with respect to the horizontal plane to guide the condensed water toward the predetermined position. In the first embodiment of the present invention, the lowest portion 316 is disposed inside the evaporating dish 301 and is set at a position where the heating device 325 is disposed.

The fan 324 has an air blowing device that can forcibly convect the air to the evaporating dish 301 to promote evaporation of the condensed water on the evaporating dish 301. That is, the moisture evaporated by the evaporating dish 301 and retained above the evaporating dish 301 will be detrimental to the evaporation efficiency, but the above-described moisture can be forcibly discharged by the fan 324, and the humidity above the evaporating dish 301 can be lowered to promote evaporation. Further, the fan 324 is not required to cool the compressor 203 of Fig. 3, but is attached to a person dedicated to promoting evaporation, so that it can be attached to a position where the above effects can be sufficiently exerted.

Further, the fan 324 is a duct structure that takes in air from the rear of the heat insulating box 101 of Fig. 5 and then discharges it toward the front side and the side surface via the evaporating dish 301. Therefore, the air having a large humidity due to evaporation will flow toward the back side, and even in the environmental conditions where the temperature around the back side is low, no condensation occurs. Secondly, the humidity of the air due to evaporation will spread toward the front of the refrigerator 100 in the open space. Conventionally, the air duct design for the heat release of the compressor 203 has been adopted. Therefore, when air is discharged to the front portion of the refrigerator 100, hot air is blown to the user's foot to cause an uncomfortable feeling.

Further, the heating device 325 is disposed so as to be placed in the piping of the lowest portion 316 of the evaporating dish 301, and is allowed to pass through the high-temperature refrigerant pumped by the compressor 203.

Moreover, the heating device 325 is attached to the lowest portion 316 in a state of being sandwiched by the holding plate 326 which is integrally provided by the evaporating dish 301 protruding upward. Next, the heating device 325 enters the lowest portion 316 from one of the evaporating dishes 301, and is piped in a U shape. Thereby, the bottom plate portion 315 can be heated by the heat transfer through the holding plate 326.

Further, although the heating device 325 constitutes a part of the cooling cycle, it is immersed in the condensed water stored in the evaporating dish 301 to come into contact with the condensed water, and therefore it is preferable to apply the rustproof treatment. Further, it may be different from the other components of the cooling cycle, and only the heating device 325 may be made of a material having a high water resistance such as stainless steel.

In the refrigerator 100 having the above configuration, the vegetable compartment 103 having a higher temperature is disposed at the lowermost portion of the heat insulating box 101, so that the thickness of the heat insulating material of the bottom portion 302 can be reduced. Therefore, the first bottom portion 321 on the front side of the heat insulating box 101 can be reduced as much as possible, so that the opening portion in the height direction of the refrigerator 100 can be utilized to the utmost, and the height and storage volume of the large drawer chamber can be ensured.

Further, since the first storage container 303 of the vegetable and fruit chamber 103 has the shape of the first bottom portion 321 and the second bottom portion 322, the volume for storage is not generated. Further, the first storage container 303 is of a drawer type and can be rubbed back and forth by a multi-layered elongated rail structure (not shown). Next, since the first storage container 303 can be pulled out from the front edge of the heat insulating box 101 to the front side, it is particularly easy to take out the work, and can be effectively utilized to the inside of the container.

Further, the bottom of the first storage container 303 can be moved back and forth along the bottom surface of the vegetable compartment 103. Further, since the predetermined gap is provided, the storage ineffective portion is generated in the height direction to prevent the first storage container 303 from being bent, the mounting accuracy of the slide rail and the storage case, and the deformation of the polyurethane foam, etc., resulting in the first The storage container 303 is in contact with the bottom surface of the vegetable compartment 103.

However, the bottom surface of the vegetable and fruit chamber 103 is stepped in the depth direction, and the first storage container 303 has a corresponding shape. Therefore, when the bottom surface of the lower portion of the third storage space corresponding to the rear portion of the first storage container 303 is pulled forward, it moves along the second bottom portion 322 and moves along the first bottom portion 321 during the drawing. Therefore, it is only necessary to ensure a gap of the moving distance in the depth direction shorter than in the past, so that it is possible to realize a design that does not increase the excess invalid volume.

Next, the bottom surface portion of the heat insulating box 101 is stepped in the depth direction, and the first storage container 303 has a corresponding shape. Therefore, the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 can be reduced. The necessary gap between the two is described in detail below.

In the refrigerator 100 according to the first embodiment of the present invention, the bottom surface portion of the heat insulating box 101 is stepped in the depth direction, and the first storage container 303 has a corresponding shape.

As described above, the flat portion in the depth direction of the bottom portion 302 is divided into the first bottom portion 321 on the front side and the second bottom portion 322 on the inner side (that is, the bottom portion 302 has been divided into two portions in the depth direction). Therefore, the amount of deformation of the bottom surface of the first storage container 303 can be reduced as compared with the case where the flat portion in the depth direction of the bottom portion 302 is not divided (that is, the bottom portion 302 is not stepped in the depth direction). Specifically, when the first storage container 303 itself is molded, the amount of bending deformation of the bottom surface of the first storage container 303 can be reduced. Further, when the bottom portion 302 of the lowermost separator is formed, the amount of deformation of the inner box due to the deformation of the polyurethane foam can be reduced. Therefore, the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 can be reduced, so that the first storage container 303 can be enlarged, and a larger storage volume can be secured.

Further, by narrowing the gap described above, it is possible to reduce the ineffective volume below the height direction without changing the height of the space in which the first storage container 303 is built into the food. Therefore, the height of the drawer compartment can be minimized, and the bottom surface of the refrigerating compartment 102 can also be a lower position, so that the refrigerating compartment 102 can be easily taken and placed, and the door of the heat insulating door 107 of the refrigerating compartment 102 is provided. The use of the rack is also convenient, and the user's convenience is improved.

Further, the refrigerator 100 is provided with a heat insulating partition plate separating the storage compartments between the storage compartments. In the above plurality of partition plates, the bottom portion 302 of the lowermost partition plate is integrally molded from a foamed heat insulating material. In the case of integral molding, a foaming inhibiting mold is used, so that the unloading slope of the foaming suppressing mold is required to be disposed in the inner box. The larger the unloading slope is, the more the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 will increase with the unloading inclination (degree of inclination), which will result in an increase in the ineffective volume.

However, as in the first embodiment of the present invention, the bottom portion 302 of the heat insulating box 101 is stepped in the depth direction, and the first storage container 303 has a corresponding shape, so that the foaming suppresses the removal depth of the mold ( That is, the length in the depth direction) will be more narrower in appearance, and the contact area between the foam suppression mold and the inner box is reduced. As a result, even if the removal slope of the inner box is reduced, the foam suppression mold can be removed, and the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 can be reduced. 1 The container 303 is housed and a larger storage volume is secured.

Next, the dimensional relationship of the first storage container 303 will be described with reference to Fig. 12 .

Fig. 12 is a cross-sectional view showing the dimensional relationship of the first storage container of the refrigerator in the first embodiment of the present invention. When the depth dimension (A1) of the first storage container 303 of the first storage container 303 is (L1), as described above, the amount of deformation of the bottom surface of the first storage container 303 is reduced as described above. In other words, it should be in accordance with A1=(1/2)×L1. Thereby, the amount of deformation of the first bottom portion 321 on the front side and the second bottom portion 322 on the inner side is substantially the same, so that the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 can be minimized, and thus The first storage container 303 is enlarged to secure a larger storage volume.

However, in addition to reducing the amount of deformation of the bottom surface of the first storage container 303 and reducing the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103, the inventors have reviewed in detail the improvement in the usability of the refrigerator 100. Achieved the following ideas. The following is a detailed description.

As a result of reviewing the improvement in the usability of the refrigerator 100, the inventors considered that (1/3) × L1 < A1 < (1/2) × L1 is a preferable range.

Specifically, when A1 < (1/2) × L1, the amount of bending deformation of the bottom surface of the third storage space 307 of the first storage container 303 and the deformation of the polyurethane foam of the second bottom portion 322 inside are caused. The amount of deformation of the box will be reduced. However, the amount of bending deformation of the bottom surface of the first storage space 305 of the first storage container 303 and the deformation amount of the inner box caused by the deformation of the polyurethane foam of the first bottom portion 321 of the front side are increased. Therefore, as a whole in the depth direction of the refrigerator 100, the amount of deformation of the bottom surface of the first storage container 303 is increased, and the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 is also increased, which is ineffective. Volume. Further, a large-sized beverage such as a 1.5-liter to 2-liter petal bottle and a heavy storage such as rice are placed in the first storage space 305. Therefore, when the storage material is stored in the first storage space 305, The amount of bending deformation of the bottom surface of the first storage space 305 of the storage container 303 may be further increased. Therefore, if the amount of bending deformation when the storage object is accommodated in the first storage space 305 is estimated, the necessary clearance between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 must be larger, so that it is more invalid. Volume. In addition, the space of the second storage space 306 and the third storage space 307 cannot be sufficiently ensured, and the storage amount of the roots and the fruits and the like is reduced, and the usability of the vegetable compartment 103 is lowered.

When A1 < (1/3) × L1, the amount of bending deformation of the bottom surface of the first storage space 305 of the first storage container 303 and the deformation of the inner box due to the deformation of the polyurethane foam of the first bottom portion 321 of the front side are obtained. The amount will decrease. However, the amount of bending deformation of the bottom surface of the third storage space 307 of the first storage container 303 and the deformation amount of the inner box due to the deformation of the polyurethane foam of the second bottom portion 322 on the inner side are increased. Therefore, as a whole in the depth direction of the refrigerator 100, the amount of deformation of the bottom surface of the first storage container 303 is increased, and the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 is also increased, thereby invalidating The volume has also increased. In addition, the storage amount of the beverages and rice having a large height such as a 1.5-liter to 2-liter PET bottle stored in the first storage space 305 is reduced, and the convenience of use of the refrigerator 100 is lowered.

That is, the bottom size (A1) of the first storage space 305 which is preferable in the first embodiment of the present invention is in the range of (1/3) × L1 &lt; A1 &lt; (1/2) × L1. The necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 is expected to be reduced, so that the ineffective volume can be reduced. Further, the storage amount of the highly-larged beverages such as the 1.5-liter to 2-liter PET bottles and the rice grains and the like are not reduced, and the space of the second storage space 306 and the third storage space 307 can be sufficiently ensured to ensure the rhizome. Since the storage amount of the type and the fruit type is not reduced, the convenience of use of the refrigerator 100 is not lowered.

When the depth dimension (L) of the first storage container 303 is about 500 mm, the size (A1) of the bottom of the first storage space 305 is preferably 167 mm < A1 < 250 mm.

Further, the inventors obtained a more detailed analysis of the range (1/3) of the bottom dimension (A1) of the first storage space 305 described above, and L1 < A1 < (1/2) × L1, and the result was obtained. The following ideas.

Specifically, if 175 mm>A1, the size of a 2 liter PET bottle commonly used in recent years is about 110 mm (width direction) × about 90 mm (depth direction) × about 310 mm (height direction), the first storage In the space 305, only one column of the 2 liter PET bottle can be accommodated in the depth direction of the refrigerator 100. Further, when a 2 liter PET bottle is placed in a row, a wasteful space is generated in the depth direction of the refrigerator 100 in the first storage space 305.

Further, if 195 mm < A1, the side of about 90 mm (depth direction) is placed in the depth direction of the refrigerator 100, and two rows of 2 liter PET bottles can be placed. However, at this time, a large amount of wasted space is also generated in the depth direction of the refrigerator 100 in the first storage space 305.

In addition, in general, it is not possible to place three rows of 2 liter PET bottles (that is, 4 bottles in the width direction × 3 bottles in the depth direction and a total of 12 bottles of 2 liters of PET bottles), not to mention Efficient space configuration.

On the other hand, the bottom size (A1) of the first storage space 305 is preferably 175 mm < A1 < 195 mm, and the reason is as follows.

In the first storage space 305, a side of about 90 mm (depth direction) of the 2 liter bottle is placed in the depth direction of the refrigerator 100, that is, a space that is less wasted in the depth direction is formed, and the space can be accommodated in the depth direction. 2 liters of PET bottles.

In the past, a space of only 2 liters of PET bottles was placed in the depth direction. Therefore, when the length of the storage container in the width direction is about 530 mm, only a total of 4 bottles of 2 liter PET bottles can be placed.

On the other hand, when the length of the first storage container 303 in the width direction is about 530 mm, the side of the first storage space 305 of about 90 mm (depth direction) is set in the depth direction, and a total of 8 bottles can be accommodated (width direction). The above 2 liter PET bottles are placed on the top of the bottle 4 bottles in the depth direction to enhance the user's convenience in using the fruit and vegetable compartment 103.

Therefore, the bottom size (A1) of the first storage space 305 is preferably 175 mm < A1 < 195 mm, and the necessary gap between the bottom surface of the first storage container 303 and the bottom surface of the vegetable compartment 103 can be reduced, so that the invalid volume can be reduced. Next, in the first storage space 305, a space which is less wasted in the depth direction is formed, and two-liter two-liter PET bottles can be accommodated in the front-rear direction, so that the user's convenience in use of the vegetable and fruit chamber 103 can be improved.

Further, the first storage space 305 for storing a large-sized beverage such as a PET bottle of 1.5 liters to 2 liters on the front side, and the third storage space 307 inside the interior of the ample space in the height direction are avoided. The evaporating dish 301 is disposed in the outer lower portion to realize space allocation without waste.

Further, the evaporating dish 301 is formed into a thin disk shape which can increase the surface area of the evaporating water surface, so that the evaporating capacity is high, and it is possible to cope with the demand for miniaturization.

Further, the increase in the evaporation capacity of the fan 324 and the heating device 325 can reduce the size of the evaporating dish 301 and enlarge the storage volume of the refrigerator 100.

Further, the machine room 201 or the evaporator (not shown) is not disposed in the rear portion of the vegetable and fruit chamber 103, and the depth of the first storage space 305 in the front portion can be enlarged by using the innermost portion as the storage space. Therefore, it is possible to store large-sized vegetables such as a two-column bottle, a seasoning containing soy sauce, and a nano-grain, etc., and it is possible to easily take out a small amount of the contents from the upper portion and accommodate the large-sized vegetables such as cabbage. As a result, the convenience of use can be improved, and the second storage space 306 and the third storage space 307 in the inside can be sufficiently ensured, and the storage space corresponding to the use of roots and fruits can be sufficiently ensured.

At this time, since the evaporating dish 301 can be disposed on the back surface of the heat insulating box 101 without being hindered by the machine such as the compressor 203, the surface area of the evaporating dish 301 can be enlarged to enhance the evaporating ability.

In the first embodiment of the present invention, an axial flow fan is used as the fan 324, but a cross flow fan, a multi-blade fan, or the like may be used.

Further, although the heating device 325 has been described as a simple cylindrical pipe body, it is also possible to provide a fin which can increase the heat release area on the surface of the heating device 325 in order to improve the heat exchange efficiency with the condensed water.

Further, if the heating device 325 is a surface heater attached to the bottom of the evaporating dish 301, the evaporating dish 301 can be supplied with a stable heating amount without being affected by the operation state of the cooling cycle and the surrounding environmental conditions. Further, since the amount of heating can be independently controlled, it is possible to achieve a corresponding design even if an unexpected increase in condensed water occurs under extreme use conditions such as a door panel for several consecutive days.

Further, in the first embodiment of the present invention, the refrigerator 203 is disposed in the refrigerator 100 above the drawer chamber. However, if the machine room 201 is disposed at the lower portion and the compressor 203 is disposed, the storage space can be effectively secured. .

Further, in the first embodiment of the present invention, the evaporating dish 301 is a thin disk-shaped one, but it is effective to increase the evaporation area of the water under the conditions of energy saving and low cost.

Further, in the first embodiment of the present invention, the evaporating dish 301 is disposed as a functional component used in the outside of the refrigerator 100 in the step space 601. However, in place of the evaporating dish 301, the control substrate can be disposed, and space allocation with less waste can be realized. The control substrate can be electrically controlled by a condenser, a compressor, a blower, various heaters, etc., and is generally used for functional components outside the refrigerator 100. Further, the functional parts may be exemplified by a compressor, a condenser, a dryer, a capillary, an evaporator, and the like which constitute a cooling cycle.

The functional components used in the outside of the refrigerator 100 are usually provided in a space such as a machine room or a substrate storage portion outside the main body of the refrigerator 100, and thus cause a crowding effect on the volume inside the casing.

Large vegetables. As a result, it is possible to achieve a capacity allocation that is satisfied by a user who has a large amount of storage in the vertical direction, and the user's convenience of use is improved more than ever. That is, a structure having a high degree of freedom in designing the space distribution in the fruit and vegetable chamber 603 can be employed.

Further, a condenser may be disposed as a heating device in the upper space of the evaporating dish 601 to increase the evaporation capacity.

(Fourth embodiment)

Next, the refrigerator according to the fourth embodiment of the present invention will be described with reference to the drawings, focusing on differences from the first embodiment. Hereinafter, the drawer structure of the rail member using the vegetable and fruit compartment will be described.

Fig. 15 is a perspective view showing the state in which the storage container of the vegetable and fruit compartment of the refrigerator according to the fourth embodiment of the present invention is in a drawer state. As shown in Fig. 15, the drawer door 702 of the vegetable compartment 701 and the refrigerator body are coupled by the support member 703 via a support member such as a frame, and form a storage container that can be pulled out and placed on the rail member 703. Construction of 704.

The storage container 704 is partitioned into a first storage portion 705 on the front side and a first storage portion 706 on the rear side by, for example, a partition plate 707. A step portion 708 is formed between the first housing portion 705 and the first housing portion 706, and the depth of the first housing portion 705 is made larger than the depth of the first housing portion 706.

Further, the first storage portion 705 and the first storage portion 706 may be separated from the storage container 704 by a partition portion or the like without using a partition plate 707 of another special component. Further, if the first storage portion 705 can secure the necessary depth, the step portion 708 may not be provided.

Next, the dimension in the depth direction of the first housing portion 705 is intentionally formed to be larger than the depth direction of the conventional vegetable compartment storage container. In other words, the dimension in the depth direction of the first housing portion 705 is a size in which two liters of a PET bottle can be arranged in the depth direction. In addition to the special bottle, it is also intended to provide storage of large-capacity seasonings such as soy sauce, and upright storage of large and heavy vegetables such as cabbage. Furthermore, in recent years, foods such as rice grains which have been gradually popularized by the habit of eating in a delicious state due to the increase in the temperature of the storage environment, such as oxidation, have been placed in a moderate cooling environment and covered by a cover. A small amount of the contents are taken out from the upper part to maintain the quality and can be easily used in the kitchen for daily use and storage.

Next, the construction of the rail member 703 will be described.

Fig. 16 is a perspective view showing a rail member of a refrigerator according to a fourth embodiment of the present invention, and Fig. 17 is an exploded view of the rail member of the refrigerator. The rail member 703 includes: a fixed rail 709, a moving rail 710, a middle rail 711 disposed between the fixed rail 709 and the moving rail 710, and a plurality of bearings 712 capable of supporting the intermediate rail 711 and the fixed rail 709 and the moving rail 710. .

The plurality of bearings 712 are rotatably held by the spherical gauge 713 as shown in Fig. 18 showing the state in which the rail members of the refrigerator according to the fourth embodiment of the present invention are mounted.

In the state in which the rail members 703 in the state in which the above-described respective components have been combined, the fixed rails 709, the moving rails 710, and the intermediate rails 711 have been integrally combined in advance, and the fixed rails 709 can be fixed to the inner side of the inner box 714 of the refrigerator body. And installed on the body side.

Specifically, the rail member 703 is attached to the left and right sides of the inner side of the inner box 714 corresponding to the fruit and vegetable chamber 701, and each of the right and left sets is attached.

Further, as shown in Fig. 18, each of the fixed rails 709 is interposed between the inner casing 714 and the fixed member 715 and the small screws 716, and is attached to the inner side surface of the inner casing 714.

Next, the moving rail 710 is coupled to the drawer door 702 via a support structure for the storage container 704, etc., and the storage container 704 is supported by the two moving rails 710 from the left and right, and synchronized with the movement of the drawer door 702 in the depth direction. Moving together with the moving rail 710 in the depth direction.

Further, at least when the drawer door 702 is fully opened, that is, when the drawer door 702 is taken out to the maximum pull-out position, the upper opening surface of the storage container 704 is opened in a nearly full-open manner, and the storage container 704 is easily slid The state of loading and unloading above.

With the above configuration, in the state in which the rail member 703 has been integrally combined in advance in the fixed rail 709, the moving rail 710, and the intermediate rail 711, each rail member can be smoothly and smoothly performed without a gap in the silent state by the bearing 712. Wipe. Therefore, it is a rail member having an extremely high strength and a high load-bearing heavy duty as compared with a conventional rail mechanism in which a roller pulley having a gap between the upper and lower sides is used in the assembly structure as in the conventional assembly.

Therefore, even if the pull-out portion is greatly increased than in the related art, the load of the storage object stored in the storage container 704 is increased and applied to the rail member 703, so that a so-called full-open type drawer which can be sufficiently withstand and has a high opening degree can be realized. Fruit and vegetable room 701.

As described in the fourth embodiment of the present invention, the intermediate rail 711 is provided between the fixed rail 709 and the moving rail 710 to further extend the wiping distance, and when the drawing portion is enlarged, the function is more effectively performed.

The storage container 704 can enlarge the depth of the first storage portion 705, and can accommodate two large liter bottles, such as two rows of PET bottles, large-sized seasonings such as soy sauce, and large vegetables such as cabbage, and can be used according to recent years. The weight of the ingredients such as rice grains expected to be temperature management is stored. Therefore, the load applied to the first housing portion 705 in front of the storage container 704 is increased. The first storage portion 705 is provided in front of the storage container 704, and the first storage portion 706 is provided behind the storage container 704. The high strength and high load resistance rail member according to the fourth embodiment of the present invention can be obtained. 703 works very effectively.

In other words, the pull-out portion is increased as much as possible, and the opening of the storage container 704 is lifted in a manner that is close to the full opening, and the storage container 704 can be easily attached and detached upward. Therefore, the storage container 704 can be easily removed and cleaned, and the sanitary requirement is maintained. Further, by using the high-strength and high-resistance heavy-duty rail member 703, it is possible to store a large load having a high load and a large load in the area before the storage container 704. As a result, it is possible to realize a fruit and vegetable compartment 701 which is much more convenient to use and more convenient than the conventional drawer type.

(Fifth Embodiment)

As described above, in the first to fourth embodiments of the present invention, the relationship between the arrangement of the functional parts outside the box and the storage container inside the case is described, and it is explained that the convenience of use can be maintained and the vegetable and fruit room can be effectively utilized.

However, if it is reviewed in detail, the correlation between the storage container inside the box and the arrangement of the functional parts outside the box is not absolutely necessary, and only the storage container inside the box is emphasized, and the convenience of use and the method of effectively utilizing the vegetable and fruit room are maintained. Then explain as follows.

So far, there is a great demand for storing more 2 liters of PET bottles, seasonings, rice, etc. in the refrigerator. Therefore, the conventional refrigerator has been placed in the door pocket of the refrigerator compartment above the refrigerator body, and accommodates a 2 liter PET bottle.

However, in the conventional refrigerator, the refrigerator compartment is located above the refrigerator body, and when a heavier 2 liter bottle is placed in the refrigerator compartment, and when it is taken out by the refrigerator compartment, it is placed at a higher position, and the wrist is caused by the wrist. The burden, etc., increases the burden on the user, not necessarily the convenience of use.

In addition, if a door pocket of a refrigerating compartment is provided with a large amount of space for accommodating a large bottle, the storage volume inside the box will be affected, and the load on the door will be increased, resulting in a tilt of the door and a lack of stability of the body when the door is opened. The problem of appearance and stability.

Hereinafter, the refrigerator according to the fifth embodiment of the present invention will be described with reference to the drawings, focusing on differences from the first embodiment. Figure 19 is a cross-sectional view showing a refrigerator according to a fifth embodiment of the present invention. As shown in Fig. 19, the refrigerator 800 is composed of a refrigerator compartment 801, a fruit and vegetable compartment 811, and a freezer compartment 802 in this order. The cooling cycle for cooling the inside of the tank is provided by a compressor 804, a condenser (not shown), a pressure reducer (not shown), and a pressure reducer (not shown) disposed in the machine room 803 at the bottom of the back of the refrigerator 800. The evaporator (not shown) is connected in a ring shape, and is sealed with a refrigerant or a refrigerating machine oil inside the pipe.

The fifth embodiment of the present invention differs from the fourth embodiment in that the first storage container 910 does not form a stepped portion between the first storage space 901 and the third storage space 903, and the first storage container 910 The bottom surface has a flat shape (planar surface), and the vegetable and fruit chamber 811 is not disposed on the lowermost layer, but is disposed on the second layer from the lowermost layer.

Next, the rail member 703 of the vegetable and fruit chamber 811 also uses the rail member described in the fourth embodiment of the present invention.

Fig. 20 is a perspective view showing the first storage container of the vegetable and fruit compartment of the refrigerator according to the fifth embodiment of the present invention in a drawer state. The drawer door 702 of the vegetable and fruit compartment 811 and the refrigerator main body are coupled by the rail member 703 via a supporting member such as a frame, and a structure in which the first storage container 910 placed on the rail member 703 can be pulled out is formed.

The first storage container 910 is partitioned into a first storage container 910 on the front side and a third storage space 903 on the inner side by, for example, a partition plate 707. The depth of the first storage space 901 is the same as the depth of the third storage space 903, and no step portion is formed between the first storage space 901 and the third storage space 903. The bottom surface of the first storage container 910 has a flat shape. Thereby, the first storage container 910 can be formed more easily.

In addition, the first storage space 901 and the third storage space 903 may be formed separately from the first storage container 910 without using a partition plate 707 of another special component.

Next, the dimension of the first housing portion 901 in the depth direction is intentionally formed to be large. That is, a size such as a 2 liter PET bottle which can be arranged in two rows in the depth direction is formed. In addition to the special bottle, it is also intended to provide storage of large-capacity seasonings such as soy sauce, and upright storage of large and heavy vegetables such as cabbage. Furthermore, in recent years, foods such as rice grains which have been gradually popularized by the habit of eating in a delicious state due to the increase in the temperature of the storage environment, such as oxidation, have been placed in a moderate cooling environment and covered by a cover. A small amount of the contents are taken out from the upper part to maintain the quality and can be easily used in the kitchen for daily use and storage.

Even if the pull-out portion is greatly increased, the load of the storage object stored in the storage container 910 is increased and applied to the rail member 703, so that a so-called full-open type drawer and fruit room that can be sufficiently tolerated and has a high opening degree can be realized. 811.

Here, the first storage container 910 can enlarge the depth space of the first storage portion 910, and can accommodate two-liter two-liter PET bottles in the depth direction, large-sized seasonings such as soy sauce, and large vegetables such as cabbage. According to the eating habits of recent years, we store the weight of ingredients such as rice grains that are expected to be temperature-managed. Therefore, the load applied to the first storage space 901 in front of the first storage container 910 is increased. The first storage space 901 is provided on the front side of the first storage container 910, and the third storage space 903 is provided inside, so that the rail member 703 having high strength and high load resistance can be effectively utilized. effect.

In other words, the pull-out portion is increased as much as possible, and the opening of the first storage container 910 is lifted in a manner that is close to the full opening, and the first storage container 910 can be easily attached and detached upward. Therefore, the first storage container 910 can be easily removed and cleaned, and the demand for hygiene can be maintained. Further, by using the rail member 703 having a high strength and a high load resistance, the storage object having a high load and a large load can be accommodated on the front side of the first storage container 910. As a result, it is possible to realize the convenience and convenience of the vegetable and fruit room 811 which is much higher than the conventional drawer type.

Further, in the fifth embodiment of the present invention, the compressor 804 is disposed on the back surface of the freezing compartment 802 (i.e., the lowermost portion of the refrigerator), and the compressor 804 is not disposed on the back side of the vegetable compartment 811. Therefore, the space of the vegetable compartment 811 can be fully utilized, and the space of the first storage space 901 in front of the first storage container 910 and the third storage space 903 on the rear side can be sufficiently ensured.

Next, the storage container in the vegetable and fruit chamber 811 will be described.

As shown in Figs. 19 and 20, the first storage container 910 is pulled out with the drawer door 702, and the first storage space 901 in which the storage object such as the large-sized bottle is accommodated in the upper and lower directions is provided in the front side. The second storage container 911 is provided in the upper portion of the first storage container 910 behind the first storage space 901, and is slidable rearward. Then, the inside of the second storage container 911 is used as the second storage space 902, and the inside of the first storage container 910 below the second storage container 911 is used as the third storage space 903.

Thereby, the vegetable and fruit room 811 has been partitioned into three spaces. Specifically, the first storage space 901 can mainly store drinks such as large-sized PET bottles of 1.5 liters to 2 liters and 1 liter paper trays, and can store vegetables to be stored vertically. Moreover, the second storage space 902 mainly accommodates fruits and small vegetables. In addition, the third storage space 903 can store large vegetables such as cabbage and Korean cabbage. In other words, it is possible to efficiently store beverages, fruits, small vegetables, and large vegetables having a large height.

Next, the dimensional relationship of the first storage container 910 will be described with reference to Fig. 21 .

Figure 21 is a cross-sectional view showing the dimensional relationship of the first storage container of the refrigerator in the fifth embodiment of the present invention. Here, the bottom size of the first storage space 901 is A2, and the depth of the first storage container 910 is L2. In recent years, the size of a commonly used 2 liter PET bottle is about 110 mm (width direction) × about 90 mm (depth direction) × about 310 mm (height direction), and if 175 mm > A2, the first storage space 901 is Only 2 liters of PET bottles can be stored in the depth direction. Further, when a 2 liter PET bottle is placed in one row, a wasteful space is generated in the depth direction in the first storage space 901.

Moreover, if 195 mm < A2, the side of about 90 mm (depth direction) is placed in the depth direction, and two rows of 2 liter PET bottles can be placed, but at this time, the first storage space 901 will also be placed. There is a lot of wasted space in the depth direction.

In addition, in general, it is not possible to place three rows of 2 liter PET bottles (that is, 4 bottles in the width direction × 3 bottles in the depth direction and a total of 12 bottles of 2 liters of PET bottles), not to mention Efficient space configuration.

On the other hand, the bottom size (A2) of the first storage space 901 of the first storage space 910 is preferably 175 mm < A2 < 195 mm, and the reason is as follows.

In the first storage space 901, the side of the two-liter liter bottle of about 90 mm (depth direction) is set in the depth direction, that is, a space that is less wasted in the depth direction is formed, and two rows can be accommodated in the depth direction. Liter bottle.

In other words, when the length of the first storage container 910 in the width direction is about 530 mm, the side of the first storage space 901 in the depth direction of about 90 mm (depth direction) is set in the depth direction, and a total of 8 bottles can be accommodated (4 in the width direction). Bottle 2 × 2 bottles in the depth direction of the above 2 liter bottle.

Fig. 22 is an explanatory view showing an upper side of the storage state of the storage item in the first storage container of the refrigerator according to the fifth embodiment of the present invention. As shown in Fig. 22, the partition plate 707 is linear from the left side to the right side of the first storage container 910. In this case, a total of 8 bottles of a 2 liter PET bottle 501 can be accommodated.

That is, the refrigerator 800 according to the fifth embodiment of the present invention includes an outer box, an inner box, a heat insulating box formed of a heat insulating material provided between the outer box and the inner box, and is disposed at a lowermost portion of the heat insulating box. The compressor 804 is disposed in a fruit and vegetable chamber 811 disposed directly below the refrigerating chamber at the uppermost portion of the heat insulating box. Next, the first storage container 910 is provided in the vegetable compartment 811, and the first storage space 901 in which the front side of the first storage container 910 is formed in the upper and lower directions and the first storage space in which the first storage container 910 is separated is provided. The third storage space 903 behind the space 901. Further, the bottom size (A2) of the first storage space 901 of the first storage container 910 is 175 mm < A2 < 195 mm.

Thereby, the space in the fruit and vegetable compartment 811 is formed to be less wasted in the depth direction, and the two-liter 2 liter PET bottle 501 can be accommodated in the depth direction, and the user's convenience in using the fruit and vegetable compartment 811 is improved.

Further, the storage volume inside the box of the refrigerating chamber 801 is not affected, and the door portion load of the refrigerating chamber 801 is not increased, and the door portion is tilted and the body stability at the time of opening the door is lacking in appearance and stability. The problem.

(Sixth embodiment)

Hereinafter, the refrigerator according to the sixth embodiment of the present invention will be described with reference to the drawings, focusing on differences from the first embodiment. Figure 23 is a cross-sectional view showing the refrigerator of the sixth embodiment of the present invention. As shown in Fig. 23, the refrigerator 850 is composed of a refrigerating chamber 801, a switching chamber 810, and an ice making chamber (not shown) arranged in parallel with the switching chamber 810, a freezing chamber 802, and a fruit and vegetable chamber 701. That is, the fruit and vegetable compartment 701 is disposed at the lowermost portion of the storage compartment.

The cooling cycle for cooling the inside of the tank is provided by a compressor 804, a condenser (not shown), a pressure reducer (not shown), and a pressure reducer (not shown) disposed in the machine room 803 at the bottom of the back of the refrigerator 850. The evaporator 820 (the back surface of the freezing compartment 802) is connected in a ring shape by piping, and a refrigerant and a refrigerating machine oil are sealed inside the piping.

That is, the vegetable compartment 701 is disposed below the evaporator 820. In the sixth embodiment of the present invention, the difference from the fifth embodiment is that the vegetable compartment 701 is disposed at the lowermost layer. Therefore, the description will be centered on the difference.

24A and 24B are explanatory views showing an upper side in a storage state of the storage item in the first storage container of the refrigerator according to the sixth embodiment of the present invention. As shown in Fig. 24A, the partition plate 717 can be used so that the left half can accommodate 2 bottles of 2 liter PET bottles 501 in the depth direction, and the right half can accommodate 1 bottle of 2 liter PET bottles 501 in the depth direction. The right side is placed further ahead than the left side. At this time, compared with the first storage container 910 shown in FIG. 22, the number of bottles that can accommodate the 2 liter PET bottle 501 is reduced, but large vegetables and the like can be accommodated in the right space.

Further, as shown in Fig. 24B, the partition plate 727 may be provided only on the left side, and the second half portion may house two bottles of the 2 liter PET bottle 501 in the front-rear direction. At this time, compared with the first storage container 910 shown in FIG. 22, the number of bottles that can accommodate the 2 liter PET bottle 501 is reduced, but a larger vegetable or the like can be accommodated in the right space.

In other words, the partition plate does not need to be linearly formed from the left side to the right side of the first storage container 910, and may be partitioned into at least a part of the field, and two bottles of a 2 liter PET bottle 501 may be accommodated in the depth direction.

In the sixth embodiment of the present invention, as shown in Figs. 24A and 24B, the compressor 804 is disposed on the right side of the bottom of the rear surface of the refrigerator 850, so that the space on the right rear side of the first storage container 910 is reduced. Therefore, the form of the partitioning plate 717 and the partitioning plate 727 which are individually shown in Fig. 24A and Fig. 24B can effectively accommodate the storage of the 2 liter PET bottle 501 and large vegetables.

Further, the partitioning plate 707 shown in Fig. 22 is linear from the left side to the right side of the first storage container 910. In this case, it is also possible to accommodate a total of 8 bottles of 2 liters of the PET bottle 501.

Further, in the sixth embodiment of the present invention, as shown in Figs. 24A and 24B, the compressor 804 is shown disposed on the right side of the bottom of the rear surface of the refrigerator 850. However, even if the compressor 804 is disposed at the center or the left side of the bottom of the back of the refrigerator, the partition plate of the field in which the compressor 804 is disposed can be placed on the front side, and the storage of the 2 liter bottle 501 and the large vegetables can be effectively taken into consideration. .

Further, the size of the first storage space 901 in the depth direction is intentionally formed to be large. Therefore, when the depth direction dimension of the third storage space 903 is smaller than a predetermined size, the depth dimension of the refrigerator 850 is increased. Alternatively, as shown in the fifth embodiment of the present invention, the vegetable compartment 811 is set to the second layer from the lowermost portion, and the height of the compressor 804 is different from the area of the vegetable compartment 811, so that the third storage space can be made. The depth direction dimension of 903 forms a predetermined size.

That is, the refrigerator 850 according to the sixth embodiment of the present invention includes an outer box, an inner box, a heat insulating box formed of a heat insulating material disposed between the outer box and the inner box, and is disposed at a lowermost portion of the heat insulating box. The compressor 804 is disposed in a vegetable compartment 701 at the lowermost portion of the heat insulating box. Next, the first storage container 910 is provided in the vegetable compartment 701, and the first storage container 910 is provided with a first storage space that is long in the vertical direction and a rear side of the first storage space that is separated from the first storage container 910. The third storage space 903. Further, the bottom size (A3) of the first storage space of the first storage container 910 of the refrigerator is 175 mm < A3 < 195 mm.

Thereby, the space in the fruit and vegetable compartment 701 is formed to be less wasted in the depth direction, and the two-liter 2 liter PET bottles 501 can be accommodated in the depth direction, and the user's convenience in using the fruit and vegetable compartment 701 is improved.

Further, the storage volume inside the box of the refrigerating chamber 801 is not affected, and the door portion load of the refrigerating chamber 801 is not increased, and the door portion is tilted and the body stability at the time of opening the door is lacking in appearance and stability. The problem.

Further, the refrigerator 850 according to the sixth embodiment of the present invention is composed of a refrigerating chamber 801, a switching chamber 810, and an ice making chamber (not shown) arranged in parallel with the switching chamber 810, a freezing chamber 802, and a fruit and vegetable chamber 701. . However, the refrigerator 850 may be configured by the refrigerating chamber 801, the freezing chamber 802, and the vegetable and fruit chamber 701 in this order without the switching chamber 810 and the ice making chamber arranged in parallel.

(Seventh embodiment)

The refrigerator of the seventh embodiment of the present invention differs from the refrigerator of the first embodiment of the present invention in the structure of the vegetable and fruit compartment. Therefore, in the seventh embodiment of the present invention, the structure of the vegetable and fruit compartment will be mainly described. Figure 25 is a front view of a refrigerator according to a seventh embodiment of the present invention, and Figure 26 is a longitudinal sectional view taken along line A-A of Figure 25.

The container 410 is a box that is pulled out with the heat insulating door 108 of the front panel, and the inside can accommodate vegetables and a bottle. The bottom of the container 410 is formed in a stepped manner toward the inner side, and can be disposed inside the bottom of the vegetable and fruit chamber 953 when the container 410 is disposed in the vegetable and fruit chamber 953.

In other words, the first storage space 103a is disposed in front of the inside of the container 410, and the second storage space 103b is disposed in the rear of the container 410. Next, a portion of the container 410 corresponding to the first storage space 103a can accommodate a large object such as a large PET bottle (such as a 2 liter PET bottle). Moreover, the second storage space 103b of the container 410 can store vegetables.

The fruit and small container 420 is a container for accommodating fruits and small vegetables, and is disposed above the fruit and vegetable compartment 953. Specifically, the fruit and small container 420 is disposed above the second storage space 103b. More specifically, the fruit and small container 420 is placed behind the upper portion of the container 410 and disposed.

The duct forming body 450 is a duct for returning the cool air in the cooled fruit and vegetable compartment 953 to the evaporation chamber 200. The air passage forming body 450 is provided with an opening portion 450a and a preliminary opening portion 450b. In other words, the duct forming body 450 forms a duct connecting the opening 450a and the preliminary opening 450b and the evaporation chamber 200.

Here, the duct forming body 450 is formed of a material having thermal conductivity and is formed of polypropylene (PP) such as resin. Further, in the seventh embodiment of the present invention, the air passage forming body 450 is made of polypropylene (PP) of a resin, but any material having thermal conductivity may be a metal such as iron.

Further, the air passage forming body 450 is disposed to be connected to the lower surface of the partitioning plate 460, and a space surrounded by the lower surface of the partitioning plate 460 and the air passage forming body 450 forms an air passage. Thereby, the lower portion of the partition plate 460 can be used as a part of the air passage, so that the air passage forming body 450 can be simply configured. Further, the cold air which is returned to the flow (details will be described later) is maintained at a low temperature by the influence of the freezing compartment 104, and the ability to cool the PET bottle accommodated in the first storage space 103a of the container 410 can be secured.

Fig. 28 is a front elevational view showing the inside of the inside of the inside of the refrigerator of the refrigerator of the seventh embodiment of the present invention. Further, for convenience of explanation, in the Fig. 28, the fruit and small container 420 has been omitted and not shown.

As shown in Fig. 28, the front surface portion 451 of the duct forming body 450 is provided with an opening portion 450a. The opening portion 450a serves as an opening of the inlet of the duct forming body 450 through which the cold air in the cooled fruit and vegetable chamber 953 passes back to the evaporation chamber 200. Further, the width of the opening portion 450a should preferably be such that the child's fingers cannot reach, specifically 5 mm.

The opening portion 450a is a vertically long circular opening, and the front surface portion 451 of the air passage forming body 450 is provided in plural in the lateral direction. In addition, the opening portion 450a may have any shape, and only needs to be an opening through which cold air can pass, and any one of them may be provided.

Here, the flow of cold air to the refrigerating compartment 102 and the fruit and vegetable compartment 953 will be described.

The cold air generated by the evaporation chamber 200 is sent to the refrigerating chamber 102 by a blower through a refrigerating compartment cooling air duct (not shown) to cool the room to a predetermined temperature. Further, the fruit and vegetable compartment 953 is blown by a cooling duct 102 through a communication duct (not shown) that blows cold air to cool the room to a predetermined temperature.

The communication duct connects the opening (not shown) provided in the lower portion of the back of the refrigerator compartment 102 to the air passage of the opening provided in the upper portion of the back of the vegetable compartment 953. Next, in the fruit and vegetable compartment 953, cold air is discharged from the opening 470 provided at the lower portion of the back of the vegetable and fruit chamber 953.

Further, the opening portion provided at the upper portion of the back of the vegetable and fruit chamber 953 and the opening portion 470 provided at the lower portion of the back of the vegetable and vegetable chamber 953 are formed by the vegetable and fruit chamber discharge duct 480 to form an air duct which is vertically connected.

In addition, as shown in Fig. 28, the vegetable and fruit room discharge conduit 480 is disposed at the right side from the center of the refrigerator, and the opening portion 470 provided at the lower portion of the back of the vegetable and fruit chamber 953 is also disposed at the right side from the center of the refrigerator.

Further, as shown in Fig. 28, the duct forming body 450 is disposed on the left side in the left-right direction of the refrigerator. Next, the dimension of the width direction of the air passage formation body 450 (the left-right direction of FIG. 28) is set to approximately 1/2 of the left-right direction of the vegetable compartment 953.

Further, the opening portion 450a is formed in substantially the entire width direction of the air passage forming body 450. Thereby, the opening portion 470 provided on the right side of the lower portion of the back of the vegetable and fruit chamber 953 shown in Fig. 28, and the opening portion 450a provided on the left side of the upper portion of the front portion of the vegetable and fruit chamber 953 are disposed in the fruit and vegetable chamber 953. The position on the corner. Therefore, in the left and right direction of the fruit and vegetable compartment 953, a substantially uniform cold air will be dispersed, and the cooling capacity of the fruit and vegetable compartment 953 can be ensured.

Further, in the seventh embodiment of the present invention, the cold air passing through the refrigerating compartment 102 is sent to the vegetable compartment 953, so that the cold air of the higher temperature is sent out compared with the cold gas which is directly blown by the evaporation chamber 200. However, the cooling of the fruit and vegetable compartment 953 is cooled by the cold air contacting the container 410. Therefore, the opening portion 470 and the opening portion 450a are disposed on the diagonal line of the inside of the vegetable compartment, and the area in which the cold air sent from the opening portion 470 comes into contact with the container 410 is large, and the cooling ability of the vegetable compartment 953 is ensured. Specifically, the cold air is blown toward the bottom surface of the container 410 by the opening portion 470 as shown by the white dotted arrow in Fig. 28, and flows to contact the container 410 to cool the fruit and vegetable chamber 953. .

Moreover, as shown in FIG. 27, the opening 450a is located above the first storage space 103a, and is disposed further forward than the front end surface of the fruit or small container 420.

Further, as shown in Fig. 27, the side surface portion 452 of the duct forming body 450 is provided with a preliminary opening portion 450b. The preliminary opening portion 450b is a preliminary opening when the opening portion 450a is blocked.

Further, as shown in Fig. 28, the preliminary opening portion 450b is disposed more outward than the side surface of the container 410 in the vegetable compartment 953. Specifically, the preliminary opening portion 450b is formed on the side surface portion on the left side of the air passage forming body 450 when the refrigerator is viewed from the front. Further, the preliminary opening portion 450b is a rectangular opening that is horizontally long, and a plurality of rectangular openings are formed in the side surface portion 452 of the air passage forming body 450 in the depth direction.

In addition, the preliminary opening portion 450b may have any shape, and only needs to be an opening through which cold air can pass, and any one of them may be provided.

Further, as shown in Fig. 28, the container 410 is provided with a through hole portion 410a through which the through hole of the cold air can flow, on the front wall included in the front portion 451. The through hole portion 410a is configured to pass a cold airflow for cooling a hole of a PET bottle or the like disposed at the front of the container 410.

Specifically, the through hole portion 410a is a vertically long circular hole, and a plurality of holes are formed in the lateral direction 3 on the front wall of the container 410.

In addition, the through hole portion 410a may have any shape, and only needs to be a hole through which the cold airflow can pass, and any one of them may be provided.

Next, the air passage forming body 450 will be described in detail.

Figure 29 is a perspective view showing a duct forming body of a refrigerator according to a seventh embodiment of the present invention. As shown in Fig. 29, the duct forming body 450 includes a front portion 451, a flat portion 453, a side surface portion 452, and a rear surface portion 454.

In addition, the front portion 451 is inclined toward the front. Thereby, the hard storage item such as apple is in a state in which the fruit and small container 420 slightly protrudes in the height direction (that is, in a state in which a storage item having a height greater than the height of the fruit or small container 420 is placed), even if the fruit, The small container 420 is moved toward the inner side of the vegetable compartment 953, and the fruit and small container 420 can be smoothly moved toward the inner side as compared with the case where the front portion 451 is not inclined. Therefore, damage such as hard storage of apples and the like can be reduced.

Further, as shown in Fig. 29, the air passage forming body 450 is provided with a rib member 450c integrally formed with the flat portion 453 in the vicinity of the central portion in the width direction of the flat portion 453. Specifically, the rib 450c is disposed in parallel with the flow direction of the cold air returning to the evaporation chamber 200, that is, parallel to the depth direction of the refrigerator. In this way, in the state in which the fruit and the small container 420 are slightly protruded in the height direction, the fruit and the small container 420 are moved toward the inside of the fruit and vegetable chamber 953 in a state in which the fruit and the small container 420 are slightly protruded in the height direction. A hard storage article such as an apple is in contact with the air passage forming body 450, and it is also difficult to deform the shape of the air passage forming body 450 without significantly impeding the flow of the cold air. Therefore, it is possible to surely ensure the flow of the cold air, so that the circulation of the cold air is not hindered. That is, the rib 450c can increase the strength of the air passage forming body 450.

As described above, in the seventh embodiment of the present invention, the air passage forming body 450 is provided on the top surface of the vegetable compartment 953 (i.e., below the partitioning plate 460). It is difficult for the user to find that the air passage forming body 450 is disposed so as to protrude downward from the top surface of the vegetable and fruit chamber 953. Therefore, a storage item having a height higher than the storage height of the fruit or small container 420 is often placed. Therefore, the front surface portion 451 of the air passage forming body 450 is inclined forward and the rib member 450c is provided on the flat surface portion 453. In the seventh embodiment of the present invention in which the air passage forming body 450 is provided on the top surface of the vegetable and fruit chamber 953, it works.

Further, in the seventh embodiment of the present invention, the rib member 450c provided in the duct forming member 453 is integrally formed with the flat portion 453, but may be formed separately from the flat portion 453.

Further, in the seventh embodiment of the present invention, the ribs 450c provided in the flat portion 453 are one, but may be two or more.

Fig. 30 is an explanatory view for cooling the cold air flow of the vegetable and fruit compartment of the refrigerator of the seventh embodiment of the present invention. As shown in Fig. 30, the cold air generated by the evaporation chamber 200 will first pass through the vegetable and fruit chamber discharge conduit 480, and then flow out through the opening portion 470, and then through the air passage 491 inside the container 410 inside the vegetable and fruit chamber 953, Below the container 410. Next, the cold air will flow from the inside under the container 410 inside the vegetable and fruit chamber 953 to the front side. Further, the cold air will flow upward from the front side of the container 410 inside the vegetable compartment 953 to the upper side. By allowing the cold air to flow in this way, the vegetables and the PET bottles contained in the container 410 can be cooled.

Next, the cold air flowing upward in front of the container 410 passes through the through hole portion 410a of the front wall of the container 410 as in the air passage 491, and then flows into the first storage space 103a. Thereby, the inflowing cold air further cools the PET bottle 511 stored in the first storage space 103a at the front of the container 410.

Then, the cold air flows toward the opening 450a of the duct forming body 450 disposed above the first storage space 103a as in the duct 492. Therefore, it is difficult for the cold air to flow to the vegetables stored in the second storage space 103b inside the container 410. That is, the stored vegetables will not be excessively cooled.

Then, the cold air passes through the opening 450a like the air passage 492, and passes through the air passage forming body 450 to return to the evaporation chamber 200.

Here, in the refrigerator 950, the temperature in the fruit and vegetable chamber 953 is adjusted, and the flow of the cold air may be temporarily stopped. That is, if the inside of the vegetable compartment 953 is excessively cooled, the temperature can be suppressed from being too low by temporarily stopping the flow of the cold air. Secondly, when the cold air flow is temporarily stopped, the cold air may flow back through the air passage forming body 450 like the air passage 493.

As described above, when the cold air passes through the air passage forming body 450 and flows back, as in the air passage 493, the opening portion 450a above the first storage space 103a flows into the first storage space 103a through the opening surface 410b. Therefore, since the first storage space 103a is cooled by the cold air, the PET bottle 511 accommodated in the first storage space 103a at the front of the container 410 can be further cooled.

In the seventh embodiment of the present invention, the upper portion of the first storage space 103a of the container 410 does not cover the upper portion of the first storage space 103a, and the first storage space 103a of the container 410 is connected to the opening 450a.

Further, since the cold air which flows back from the air passage forming body 450 flows toward the first storage space 103a at the front portion of the container 410, the vegetables stored in the second storage space 103b at the rear of the container 410 are not excessively cooled.

Further, the fruit and small container 420 contains foods such as fruits and small vegetables. Here, the opening portion 450a of the air passage forming body 450 is disposed further forward than the front end surface of the fruit or small container 420. Therefore, it is possible to prevent the small vegetable or the like stored in the fruit or small container 420 from blocking the opening portion 450a or hindering the circulation of the cold air.

Further, the side surface portion of the air passage forming body 450 is provided with a preliminary opening portion 450b which is disposed outside the side of the container 410 in the vegetable compartment 953. Therefore, when the opening portion 450a of the air passage forming body 450 is blocked, the preliminary opening portion 450b can be prevented from being blocked. Therefore, the minimum amount of air can be supplied from the preliminary opening portion 450b without obstructing the circulation of the cold air.

Further, since the preliminary opening portion 450b is disposed more outward than the side surface of the container 410, the vegetables stored in the second storage space 103b inside the container 410 are not excessively cooled even if the cold air flows backward.

Further, the air passage forming body 450 has the following features.

The duct forming body 450 is disposed directly below the partition plate 460 partitioning the vegetable compartment 953 and the freezing compartment 104. Therefore, the airflow forming body 450 and the counter-flowing cold air are maintained at a low temperature by the influence of the freezing compartment 104, and the ability to cool the PET bottle 511 accommodated in the first storage space 103a of the container 410 can be secured.

Further, the duct forming body 450 is made of a heat conductive material such as polypropylene of a resin. Therefore, the cold air that has returned to the evaporation chamber 200 during the operation of the blower 100a by the air passage forming body 450 and the cold air that flows back from the evaporation chamber 200 when the blower 100a is stopped can be radiated by the air passage forming body 450, and the second storage is performed. The fruits and small vegetables stored in the vegetables, fruits, and small containers 420 stored in the space 103b are cooled as scheduled without excessive cooling.

In other words, the duct forming body 450 can ensure the ability to actively cool the cold air that has passed through the first storage space 103a of the container 410 in which the PET bottle 511 is stored. In addition, the second storage space 103b of the container 410 for storing vegetables and the fruit or small container 420 for storing fruits and small vegetables can be cooled by predetermined cooling by the cold air, without excessive cooling.

In other words, the air passage forming body 450 can realize cooling mainly in the vegetable compartment 953 as the cooling zone (the first storage space 103a) and mainly as the fresh-keeping zone (the second storage space 103b and the fruit and small container 420) by the cold air passing therethrough. .

Further, in the seventh embodiment of the present invention, as described above, the specific form of the air passage forming body 450 has been described. However, the conceptual structure in which the above-described effects can be achieved and the effect is achieved will be described below.

In the vegetable compartment 953 of the refrigerator 950 according to the seventh embodiment of the present invention, the first storage space 103a that can open the top of the bottle 511 and the like, and the fruit and the small container that can store the fruit and the small vegetables in the upper rear layer are disposed. 420. The second storage space 103b for storing vegetables or the like can be stored in the lower layer. Next, in the vicinity of the opening portion 450a at a position above the small object container 420 or the second storage space 103b, a radiant cooling plate (air passage forming body 450) that can act as a cooling source from the cold air of the evaporation chamber 200 is provided. Therefore, when the blower 100a is in operation, the chilled cooling plate is cooled by passing the cold air on the back surface of the radiating surface of the radiant cooling plate on the path returning to the evaporation chamber 200. Further, when the blower 100a is stopped, the radiant cooling plate is cooled by radiating the cold air on the back surface of the cooling plate by the evaporation chamber 200 flowing back toward the vegetable compartment 953. As a result, the radiant cooling plate can exhibit a cooling action in the second storage space 103b of the container 410 in which the vegetables can be stored, the fruit and the small container 420 which can accommodate fruits and small vegetables.

In addition, in the positional relationship in which the backflow cooling air flows into the first storage space 103a of the container 410 through the back surface of the radiant cooling plate, the front end surface of the radiant cooling plate is added, and the hopper bottle 511 of the first storage space 103a can be accommodated. The effect of the object to promote cooling.

As described above, the cold air passing through the back surface of the radiant cooling plate passes through the reverse flow phenomenon when the blower 100a is also stopped, thereby providing a cooling structure of the vegetable and fruit chamber 953 which is extremely reasonable in cooling efficiency.

Further, as described above, if the backflow phenomenon from the evaporation chamber 200 when the blower 100a is stopped can be utilized, the evaporation chamber 200 can be easily disposed above the upper portion of the vegetable compartment 953 as in the seventh embodiment of the present invention. Specifically, the evaporation chamber 200 is disposed at a position where the arrangement height of the radiation surface of the radiant cooling plate (the air passage forming body 450) is high so that at least a portion of the evaporation chamber 200 is located at the position. As a result, since the proportion of the cooled air, that is, the cold air, is relatively large, the convection of the cold air due to natural convection will also occur when the blower 100a is stopped, which forms a countercurrent phenomenon and flows into the fruit and vegetable chamber 953 through the radiant cooling plate.

Next, the radiant cooling plate with the radiation surface facing the fruit and vegetable chamber 953 is disposed at a lower portion of the partitioning plate 460 separating the freezing chamber 104 and the vegetable and fruit chamber 953, and is formed between the radiating surface of the radiant cooling plate and the partitioning plate 460. Radiation can be exerted by the space of the cold air flow.

In the seventh embodiment of the present invention, the above-described configuration has been referred to as a specific form of the air passage forming body 450 by means of a so-called duct. Therefore, the object of the present invention is not limited to the embodiment of the air duct forming body 450 of the refrigerator according to the seventh embodiment of the present invention, and the concept of the radiant cooling plate having the radiating surface of the embodiment is an effective structure.

As described above, according to the present invention, the PET bottle to be cooled and the vegetable to suppress excessive cooling can be cooled.

The details of the embodiments disclosed herein are illustrative in nature and are not intended to limit the scope of the invention. The scope of the present invention is defined by the scope of the claims, and is intended to be

In the seventh embodiment of the present invention, the preliminary opening portion 450b is disposed more outward than the side surface of the container 410 in the vegetable compartment 953. However, the preliminary opening portion 450b may be further disposed outside the side of the fruit or small container 420 in the fruit and vegetable compartment 953. Thereby, the clogging of the preliminary opening portion 450b due to the food can be prevented.

Further, in the seventh embodiment of the present invention, as shown in Fig. 28, the duct forming body 450 is disposed on the left side in the left-right direction of the refrigerator, and the dimension in the width direction of the duct forming body 450 is set to the left and right of the vegetable compartment 953. The direction is roughly 1/2. However, the width direction of the air passage forming body 450 may be substantially the same as the width direction of the fruit and small object container 420, and a flange is provided downward at the side surface portion of the air passage forming body 450 to block the fruit and small object container 420. Open above. Thereby, the cold air will be more difficult to flow to the area of the fruit and small container 420, and the drying of the food in the fruit and small container 420 can be prevented.

Further, at this time, from the viewpoint of uniformly cooling the fruit and vegetable compartment 953, the right half of the width direction of the air passage forming body 450 is preferably not provided with the opening portion 450a.

Further, the upper end portion of the fruit and small container 420 may be extended to the vicinity of the air passage forming body 450 to block the opening of the upper surface of the fruit and small container 420. Thereby, it is possible to make the cold air more difficult to flow to the area of the fruit and small container 420, and further prevent the drying of the food in the fruit and small container 420.

Further, the air passage forming body 450 may be provided in the range of the bottom dimensions A1, A2, and A3 of each of the first storage spaces described in the first, fifth, and sixth embodiments of the present invention. In this way, more pods can be stored in the fruit and vegetable compartment 953, and the areas to be cooled in the fruit and vegetable compartment 953 and the areas in which cooling is to be suppressed can be distinguished.

As described above, even if the number of the bottle that can be accommodated is increased, the structure of the seventh embodiment of the present invention which is cooled by the backflow phenomenon using the air passage forming body has an effect.
