Description

TECHNICAL FIELD The present invention relates to a refrigerator, and more particularly to a refrigerator employing a transparent member as a partition member for partitioning adjacent storage compartments.

In a general refrigerator, a storage room such as a refrigerating room is formed inside a heat-insulating box body, and the refrigerating cycle is controlled so that the storage room has a temperature zone suitable for cooling and preserving stored items. cooled by

By blowing air cooled by the refrigerating cycle to each storage compartment, the refrigerating compartment and the vegetable compartment are cooled to the refrigerating temperature zone, and the freezing compartment is cooled to the freezing temperature zone.

A refrigerating compartment and a vegetable compartment cooled to a refrigerating temperature zone and a freezer compartment cooled to a freezing temperature zone are partitioned by a heat insulating partition material containing urethane resin. On the other hand, since both the refrigerating compartment and the vegetable compartment are storage compartments in the refrigerating temperature range, a member with low heat insulation such as a resin plate is adopted as the partitioning member that separates the refrigerating compartment from the vegetable compartment. A refrigerator having such a configuration is described in Patent Document 1, for example.

Hereinafter, refrigerator 10 concerning an embodiment of the present invention is explained in detail based on a drawing. In the description of the present embodiment, in principle, the same reference numbers are used for the same members, and repeated descriptions are omitted. Although the present embodiment will be described using each direction of up, down, front, back, left, and right, left and right are left and right when the refrigerator 10 is viewed from the front.

FIG. 1 is a perspective view of a refrigerator 10 according to an embodiment of the present invention as seen from the front left side. Refrigerator 10 has heat insulating box 11 and a storage room formed inside heat insulating box 11 . It has a refrigerator compartment 12, a vegetable compartment 121 and a freezer compartment 13 as storage compartments. The front opening of the refrigeration compartment 12 is closed with a rotary heat insulating door 18, and the front opening of the vegetable compartment 121 is closed with a drawer type heat insulating door 19. - 特許庁A front opening of the freezer compartment 13 is closed by a drawer-type heat insulating door 20 and a heat insulating door 21 .

FIG. 2 is a side sectional view of refrigerator 10. As shown in FIG. Referring to this figure, the heat insulating box 11 comprises an outer box 111 made of steel plate bent into a predetermined shape, an inner box 112 made of a synthetic resin plate disposed inside the outer box 111 and separated from the outer box 111, and an outer box 112 made of synthetic resin. It is composed of a heat insulating material 113 filled between a box 111 and an inner box 112 .

The storage compartment inside the heat insulating box 11 is divided into a refrigerator compartment 12, a vegetable compartment 121 and a freezer compartment 13 from above. The refrigerating chamber 12 is a refrigerating temperature zone storage chamber for storing perishable foods and beverages. The vegetable compartment 121 is a refrigerator temperature zone storage compartment in which vegetables, fruits, and the like are stored. The freezer compartment 13 is a storage compartment in a freezing temperature zone in which frozen foods, ice, and the like are stored. An example of the internal temperature of each storage compartment will be described. The internal temperature of the refrigerator compartment 12 is 2° C. or higher and 6° C. or lower (for example, 3° C.), and the internal temperature of the vegetable compartment 121 is 5° C. or higher and 7° C. or lower (e.g., 3° C.). for example, 6° C.), and the internal temperature of the freezer compartment 13 is −20° C. or more and −18° C. or less (eg, −19° C.).

The interior of the refrigerator compartment 12 is vertically partitioned by a plurality of storage shelves 15 . A storage container 25 that can be pulled forward and backward is arranged in the lower part of the refrigerator compartment 12 . A storage container 26 that can be drawn forward and backward is arranged below the storage container 25 . The interior of the storage container 26 is cooled, for example, to −1° C. or higher and +1° C. or lower (eg, 0° C.), and is used as a chilled chamber for storing fish or meat. Storage container 26 is kept at a lower temperature than other regions of refrigerating compartment 12 by direct blowing of cool air from blowing path 118 . A specific configuration of the container 26 will be described later with reference to FIGS. 3 and 4. FIG. Further, the storage container 25 and the storage container 26 are made of transparent synthetic resin.

The refrigerator compartment 12 and the vegetable compartment 121 are separated by a partition member 23. - 特許庁Also, the partitioning member 23 is composed of a transparent partitioning member 231 and a heat insulating partitioning member 232 .

The transparent partition member 231 is made of a transparent plate-like material such as a tempered glass plate, and constitutes the front portion of the partition member 23 . By adopting the transparent partition member 231, the vegetables and the like stored in the storage container 27 of the vegetable compartment 121 can be visually recognized from the refrigerator compartment 12 without pulling out the heat insulating door 19 and the storage container 27 to the front. Specifically, the user can pass through the transparent partition member 231 from above without pulling out the heat insulation door 19 in a state where the rotary heat insulation door 18 is opened, and the vegetables stored in the vegetable compartment 121 can be opened. Fruit can be seen.

The heat insulating partition member 232 is a member forming the rear portion of the partition member 23, and is filled with a heat insulating material made of foamed resin such as urethane. By including a heat insulating material in the heat insulating partition member 232, it is possible to insulate the chilled room inside the storage container 26 where the inside temperature is about 0°C and the vegetable room 121 where the inside temperature is about 5°C. Dew condensation on the lower surface of the storage container 26 can be suppressed.

A storage container 27 is stored in the vegetable compartment 121 . The storage container 27 is slidably arranged inside the inner box 112 so that it can be pulled out together with the heat insulating door 19 . A specific configuration of the container 27 will be described later with reference to FIGS. 3 and 4. FIG.

The refrigerator compartment 12 and the freezer compartment 13 are separated by a heat insulating partition wall 36 filled with a heat insulating material such as urethane.

A cooling chamber 115 is defined on the back side of the freezing chamber 13, and an evaporator 116 is accommodated in the cooling chamber 115. - 特許庁A blower 35 is arranged inside the cooling chamber 115 and above the evaporator 116 . Further, an air passage 118 is connected to the upper part of the cooling chamber 115 . The air cooled by the evaporator 116 in the cooling chamber 115 is blown to the air passage 118 by the blowing force of the blower 35 . The air cooled by evaporator 116 is also sent to freezer compartment 13 via an opening formed in front of cooling compartment 115 .

A defrosting heater 117 is arranged inside the cooling chamber 115 and below the evaporator 116 . The defrosting heater 117 is a heater that generates heat when energized, and generates heat when energized in the defrosting process, and the generated heat melts the frost on the evaporator 116 . The defrosted water generated by defrosting reaches an evaporating dish (not shown) and evaporates by exchanging heat with a high-temperature compressed refrigerant.

Inside the freezer compartment 13, a storage container (not shown) is arranged. When the heat insulating door 20 and the heat insulating door 21 are pulled forward, these storage containers are also pulled forward.

Here, the refrigerator compartment 12 described above corresponds to the first storage compartment, the vegetable compartment 121 corresponds to the second storage compartment, and the chilled compartment formed inside the container 26 corresponds to the small storage compartment.

The internal configuration of the refrigerator compartment 12 will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is a cutaway perspective view of the interior of the refrigerating chamber 12 viewed from below, and FIG. 4 is a cutaway perspective view of the interior of the refrigerating chamber 12 viewed from above. Here, storage container 26 and storage container 27 are shown pulled forward from refrigerator compartment 12 .

Referring to FIG. 3, storage container 26 is a generally box-shaped container with an upper opening, and is made of plate-shaped synthetic resin. The front portion of the storage container 26 is composed of a lower lid portion 262 forming a lower portion and an upper lid portion 261 forming an upper portion. The lower lid portion 262 is continuous with the bottom surface of the storage container 26 . A gap 263 is formed between the lower end of the upper lid portion 261 and the upper end of the lower lid portion 262 . The gap 263 is a portion for discharging the air that has cooled the interior of the storage container 26, which is the chilled chamber, toward the front of the storage container 26. As shown in FIG. This matter will be described later with reference to FIG.

Further, as shown in FIG. 4, a storage container opening 264 is formed by opening a rear side surface 266 of the storage container 26 . An air passage opening 29 is formed by opening the rear surface of the refrigerator compartment 12 . Cool air that has passed through the air passage 118 shown in FIG. 2 is blown out from the air passage opening 29 . When refrigerator 10 is viewed from the front, storage container opening 264 of storage container 26 and air passage opening 29 of refrigerator compartment 12 are positioned to overlap each other. With such a configuration, the air cooled by the evaporator 116 shown in FIG. 2 can be blown directly into the storage container 26, and the inside of the storage container 26 can be maintained at a low temperature of about 0.degree.

The storage container 27 is a synthetic resin container that is stored inside the vegetable compartment 121 and has a bottom surface 273 , a front side surface 271 and a rear side surface 272 . A storage container opening 274 is formed by opening the upper portion of the front side surface 271 in a slit shape. A plurality of storage container openings 274 are formed in a row along the left-right direction.

3 and 4, a partition member opening 28 is formed at the rear end of the heat insulating partition member 232. As shown in FIG. The partitioning member openings 28 are slit-shaped openings that penetrate the heat insulating partitioning member 232 in the vertical direction, and are formed in plurality along the horizontal direction. The partitioning member opening 28 is an opening for guiding the air after cooling the storage container 26 to the vegetable compartment 121 .

Referring to FIG. 4, a return port 30 is formed at the lower end on the left side of the rear end of vegetable compartment 121 . The return port 30 is an opening through which the air that has cooled the inside of the refrigerator compartment 12 is sucked, and the sucked air is returned to the cooling compartment 115 shown in FIG. Here, rectangular return ports 30 are arranged in a matrix. Although not shown here, the return port 30 is also formed at the rear right end of the vegetable compartment 121 .

By forming the return port 30 at the rear end of the vegetable compartment 121, most of the cold air introduced into the vegetable compartment 121 through the partitioning member opening 28 returns without being sent to the front of the vegetable compartment 121. - 特許庁Since it is possible to inhale from the mouth 30, the lower surface of the transparent partition member 231 arranged on the front upper surface of the vegetable compartment 121 is not cooled excessively. As a result, it is possible to prevent condensation from forming on the lower surface of the transparent partition member 231 . In addition, excessive cooling of the vegetable compartment 121 can be suppressed.

FIG. 5 is a perspective view of the inner box 112 as seen from the rear. The upper part of the inner box 112 forms the refrigerator compartment 12 and the lower part of the inner box 112 forms the freezer compartment 13 . The return port 30 is formed at the rear end of the vegetable compartment 121 formed in the lower portion of the refrigerator compartment 12 . Two return ports 30 are formed at both left and right ends of the rear end portion of the vegetable compartment 121 .

A return air path 31 is connected to each of the return ports 30 . The return air passage 31 is a duct-like member arranged at both left and right ends behind the inner box 112 . By doing so, it is possible to prevent interference between the return air passage 31 and the air passage 118 (see FIG. 2) arranged in the rear center of the inner box 112 . Also, the lower end of the return air passage 31 is connected to an opening formed at the lower end of the cooling chamber 115 . With this configuration, the air returned from the return port 30 can be returned to the lower end of the cooling chamber 115 via the return air passage 31 .

A connection configuration of the refrigerator 10 having the configuration described above will be described with reference to the block diagram of FIG. Refrigerator 10 includes arithmetic control unit 24 , temperature sensor 32 , timer 33 , compressor 22 , blower 35 and defrosting heater 117 .

The arithmetic control unit 24 is composed of, for example, a CPU, receives inputs from various sensors, performs predetermined arithmetic processing, and controls operations of various constituent devices such as the compressor 22 based on the processing results. Further, the arithmetic control unit 24 may include a semiconductor storage device that stores various constants and programs for performing the cooling operation. The arithmetic control unit 24 sets each storage room to an indoor temperature range suitable for storing the items to be stored, and the defrosting process is performed at an appropriate timing.

A temperature sensor 32 and a timer 33 are connected to input terminals of the arithmetic control unit 24 . A temperature sensor 32 is attached to each of the above-described storage compartments to measure the internal temperature of these compartments. The timer 33 measures the cooling time for cooling each storage compartment, the operating time of the defrosting heater 117, and the like.

The compressor 22 , the blower 35 and the defrosting heater 117 are connected to output terminals of the arithmetic control unit 24 . Various devices such as the compressor 22 operate based on output signals output from the arithmetic control unit 24 .

When the refrigerator 10 is operated for cooling, the arithmetic control unit 24 operates the compressor 22 and the blower 35 so that the temperature of each storage measured by the temperature sensor 32 falls within a predetermined temperature range. Air cooled by a vapor compression refrigeration cycle including the compressor 22 is blown into each storage compartment, thereby cooling each storage compartment to a predetermined temperature zone.

Further, when frost formation on the evaporator 116 reaches a certain level or more, a defrosting process is performed to melt the frost that has grown on the evaporator 116 . Frost formation in the evaporator 116 is detected, for example, when the cooling time measured by the timer 33 reaches a constant value. In the defrosting process, the compressor 22 and the blower 35 are stopped, and the defrosting heater 117 is energized to melt the frost adhering to the evaporator 116 .

Referring to FIGS. 7 and 8, the cooling of each storage compartment using the vapor compression refrigeration cycle evaporator 116 will be described. 7 is a side cross-sectional view of refrigerator 10, and FIG. 8 is a side cross-sectional view showing air flow in storage container 26 and vegetable compartment 121. As shown in FIG. In FIGS. 7 and 8, the direction of air flow is indicated by a dotted arrow, and the length of the arrow indicates the magnitude of the air volume.

Referring to FIG. 7 , in the cooling operation of refrigerator 10 , evaporator 116 first cools the air inside cooling chamber 115 . The air cooled by the evaporator 116 inside the cooling chamber 115 is blown to the air passage 118 by the blower 35 . The air blown into the air passage 118 is blown out into the refrigerator compartment 12 through an air outlet formed in the front surface of the air passage 118, so that the inside of the refrigerator compartment 12 is kept in a predetermined freezing temperature zone. The air that has cooled the refrigerator compartment 12 enters the vegetable compartment 121 through the partitioning member opening 28 formed behind the heat insulating partitioning member 232 . The air that has cooled the vegetable compartment 121 is returned to the cooling compartment 115 via the return port 30 and the return air passage 31 . Also, part of the air blown to the air passage 118 is directly blown into the storage container 26 . This matter will be described later with reference to FIG.

Also, part of the air cooled by evaporator 116 circulates inside freezer compartment 13 . As a result, the inside of the freezer compartment 13 is set to a freezing temperature zone.

The flow of air for cooling the storage container 26 and the vegetable compartment 121 will be described with reference to the cross-sectional view of FIG. First, part of the air blown to the air passage 118 enters the chilled chamber inside the storage container 26 through the air passage opening 29 and the storage container opening 264 . As a result, air is blown directly from the air passage 118 to the storage container 26, so that the inside of the storage container 26 is cooled to a temperature suitable for chilled storage of meat, fish, etc., for example, about 0°C. . The air that has cooled the interior of the storage container 26 advances forward of the storage container 26 through a gap 263 formed at the front end of the storage container 26 . The air blown forward from the gap 263 travels rearward between the bottom surface 265 of the storage container 26 and the heat insulating partition member 232 . By doing so, the transparent partitioning member 231 is not cooled excessively, so that the formation of dew condensation on the transparent partitioning member 231 can be suppressed.

After that, the air enters the vegetable compartment 121 through the partition member opening 28 . Most of the air that has entered the vegetable compartment 121 , at least half or more, is sucked into the return port 30 via the rear side surface 272 of the storage container 27 .

On the other hand, part of the air that has entered the vegetable compartment 121 through the partitioning member opening 28 , that is, less than half of the air, travels forward inside the vegetable compartment 121 . As a result, the inside of the vegetable compartment 121 has a temperature range of about 5° C. suitable for refrigerating vegetables and fruits. After that, the air that has cooled the vegetable compartment 121 flows downward between the front side surface 271 and the heat insulation door 19 through a storage container opening 274 formed in the upper portion of the front side surface 271 of the vegetable compartment 121 . proceed. After that, the air travels rearward between the bottom surface 273 of the storage container 27 and the heat insulating partition wall 36 and is sucked into the return port 30 .

By reducing the amount of air circulating inside the vegetable compartment 121 in this manner, the internal temperature of the vegetable compartment 121 can be set to a temperature range of about 5° C., which is preferable for preserving vegetables and the like. Furthermore, since the amount of cold air flowing near the lower surface of the transparent partition member 231 can be restricted, the occurrence of dew condensation on the transparent partition member 231 can be suppressed. Therefore, the user can visually recognize the objects such as vegetables stored inside the vegetable compartment 121 through the transparent partition member 231 .

Here, the air introduced into the vegetable compartment 121 from the partitioning member opening 28 is divided into a part that enters the rear side of the rear side surface 272 of the storage container 27 and a part that enters the vegetable compartment 121 toward the front side. However, the ratio of both can be changed as appropriate. For example, the ratio of the air entering the rear side of the rear side surface 272 of the storage container 27 is preferably 70%, more preferably 80%, of the air introduced into the vegetable compartment 121 from the partition member opening 28. , particularly preferably 90%. On the other hand, the ratio of the air entering the vegetable compartment 121 toward the front side is preferably 30%, more preferably 20%, particularly Preferably, it can be 10%. By doing so, the amount of cold air reaching the lower side of the transparent partition member 231 is restricted, the occurrence of dew condensation on the transparent partition member 231 is suppressed, and the internal temperature of the vegetable compartment 121 is kept within a suitable refrigeration temperature range. can be maintained.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
