The cooling chamber 13 partitioned and formed by the partition member 39 is provided in the inner side of the supply air path 14 inside the inner case 2b. An opening connecting the cooling chamber 13 and the supply air path 14 is formed in the partition member 29 on the upper part of the cooling chamber 13, and a first air blower 32 for circulating air is disposed on the opening. On the other hand, the opening 13b which inhales the cold return air from a storage room into the inside of the cooling room 13 is formed in the lower part of the cooling room 13. As shown in FIG.

A storage container 29 for storing objects to be frozen such as foods is provided in the upper freezer compartment 5 . The storage container 29 is a substantially box-shaped synthetic resin container with an upper opening. The storage container 29 is assembled in an unillustrated frame body fixed to the door 10 , and is configured to be able to be drawn out forward together with the door 10 .

In addition, in this embodiment, the mounting plate 24 is arrange|positioned inside the storage container 29. As shown in FIG. Thereby, the air path under the mounting plate 24 can be ensured, and the object to be frozen, such as a food, can be cooled more efficiently through supercooling. Therefore, the ice crystals of foodstuffs to be frozen are small, and the cells of foodstuffs are less likely to be damaged, thereby suppressing the generation of water droplets. This matter will be described in detail with reference to FIG. 5 and the like.

A cooler 33 (evaporator) for cooling circulating air is disposed inside the cooling chamber 13 . The cooler 33 is connected to the compressor 31 , a radiator (not shown), and an expansion valve (capillary) (not shown) through refrigerant pipes to constitute a vapor compression refrigeration cycle. In addition, in the refrigeration equipment 1 according to the present embodiment, isobutane (R600a) is used as the refrigerant of the refrigeration cycle.

Next, the basic cooling operation of the refrigeration equipment 1 having the above configuration will be described.

First, the air in the cooling chamber 13 is cooled by the cooler 33 of the above-mentioned vapor compression refrigeration cycle. The air cooled by cooler 33 is discharged from the opening of cooling chamber 13 to supply air passage 14 by first blower 32 .

Then, part of the cooling air discharged from the supply air passage 14 is adjusted to an appropriate flow rate by the air passage switch 18 (for example, a motor damper), flows to the supply air passage 15 , and is supplied to the refrigerator compartment 3 . Thereby, foodstuffs etc. stored inside the refrigerator compartment 3 can be cooled and stored at an appropriate temperature.

The cold air supplied to the inside of the refrigerator compartment 3 is supplied to the vegetable compartment 7 through a connecting air passage not shown. The cold air circulated in the vegetable compartment 7 returns to the inside of the cooling compartment 3 through the return air passage 17 and the opening 13 b of the cooling compartment 13 . Therefore, cooling is performed by the cooler 33 again.

On the other hand, part of the cooling air discharged from the supply air duct 14 is supplied to the ice making compartment 4 and the upper freezer compartment 5 . And, the air in the ice-making compartment 4 and the upper freezer compartment 5 flows to the lower freezer compartment 6 connected, and the air in the lower freezer compartment 6 flows through the bottom of the lower freezer compartment 6, and flows to the bottom of the cool compartment 13 through the opening 13b of the cool compartment 13. internal.

As described above, the air cooled by the cooler 33 is circulated in the storage room, and food and the like are frozen or cooled and stored. In this embodiment, a subcooling mode is provided for cooling the object to be frozen stored in the upper freezer compartment 5 according to the user's operation, and this function will be described below with reference to FIG. 5 and the like.

Next, the configuration near the upper freezer compartment 5 will be described in detail with reference to FIGS. 3 to 6 .

As shown in FIGS. 3-5 , the loading plate 24 has a plurality of ventilation holes 25, and the bottom of the loading plate 24 is provided with a support 241, and the loading plate 24 is placed on the support 241. Inside the storage container 29 of the freezer compartment 5 . Under the action of the supporting member 241 , a space is formed between the loading plate 24 and the bottom of the storage container 29 , and the storage container 29 is divided into two spaces by the loading plate 24 . Specifically, the internal space of the storage container 29 is divided into a first area 44 above the placement plate 24 and a second area 45 below the placement plate 24 . The first area 44 is an area for accommodating objects to be frozen 26 such as foods to be frozen, and the objects to be frozen 26 are placed on the upper surface of the placing plate 24 . The second area 45 is an area narrower than the first area 44 in the vertical direction, and is an area through which cool air passes in use. Inside the storage container 29 , the communication between the first area 44 and the second area 45 is carried out through the ventilation holes formed in the mounting plate 24 . Wherein, as an example for the convenience of processing, the edges of part of the ventilation holes 25 are formed with the support members 241 protruding downward. At 26 o'clock, the supporting member 241 can effectively support the loading plate 24 , so as to avoid bending the loading plate 24 due to the weight of the object 26 to be frozen. In addition, a pair of side edges of the loading board 24 is formed with a downwardly bent supporting flange 242 , and the loading board 24 can be further supported by the supporting flange 242 .

As shown in FIGS. 3 , 4 and 6 , partition member 20 is a member made of plate-shaped resin, and partitions the air passage at the upper end of upper freezer compartment 5 . A plurality of communication ports 21 are formed on the partition member 20 in a predetermined shape and arrangement so that cold air from the upper freezer compartment 5 can pass through uniformly. The opening 22 is formed behind the communicating port 21 , that is, on the back side of the upper freezer compartment 5 , and the second air blower 23 is disposed on the opening 22 . In other words, the second air blower 23 is arranged behind the communication port 21 and is installed near the air outlet 28 where the cool air from the supply air path 14 flows into. The second air blower 23 is an axial flow air blower in which a rotary fan is accommodated in a casing. The casing of the second air blower 23 is fixed to the upper surface side of the spacer member 20 .

A temperature sensor 34 is arranged above the upper freezer compartment 5 . The temperature sensor 34 is, for example, an infrared sensor, and measures the surface temperature of the object to be frozen 26 placed on the mounting plate 24 . In this embodiment, when the supercooling mode is performed according to the user's request, the temperature of the object to be frozen 26 is measured by the temperature sensor 34 and the freezing function of the upper freezer compartment 5 is adjusted.

When the second blower 23 is activated for supercooling mode, the cold air cooled by the cooler 33 is blown to the first area of the upper freezer compartment 5 by the blowing effect of the second blower 23 to form the air passage 40 . Here, the direction of the wind passage 40 is downward obliquely forward.

Therefore, part of the cool air forming the air passage 40 enters the second region 45 from the second air blower 23 through the vent hole 25 of the mounting plate 24 . Thereafter, the cold air moves forward in the second area 45 to form the air passage 41 . In addition, a part of cool air forming the air passage 40 can be blown toward the object 26 to be frozen.

Inside the second area 45 , the cold air that has flowed to the vicinity of the front end of the upper freezer compartment 5 moves from the second area 45 toward the first area 44 through the ventilation holes 25 of the mounting plate 24 . As a result, the air passage 42 flowing upward is formed inside the first region 44 .

Thereafter, the cool air constituting the air passage 42 enters between the partition member 20 and the heat insulating partition wall 36 through the communication port 21 provided on the partition member 20 . Furthermore, an air passage 43 is formed in which the cold air flowing into this area flows backward. The air passage 43 reaches the second air blower 23 .

As can be seen from the above, when the second air blower 23 is operated under the use condition, the air passages 40 , 41 , 42 , and 43 form the passages for circulating cold air in this order. Thereby, the temperature difference in the inside of the upper freezer compartment 5 becomes small, and supercooled freezing can be performed.

In addition, in the present embodiment, in the subcooling mode, not only the sides and the upper side of the object to be frozen 26 but also the lower side are formed with an air passage to circulate cold air. Therefore, since the object to be frozen 26 is uniformly frozen from the periphery at a low temperature of, for example, -20° C. or lower, the internal temperature difference becomes small, and supercooling easily occurs.

In addition, in this embodiment, the object 26 to be frozen is placed on the upper surface of the mounting plate 24 in which the some ventilation hole 25 was formed. Therefore, since the cool air flowing in from below through the vent hole 25 contacts the object 26 to be frozen, the object 26 as a whole is cooled, and a state in which supercooling is likely to occur can be realized.

Furthermore, in this embodiment, the temperature sensor 34 is arranged above the object 26 to be frozen, and the cooling function for cooling the upper freezer compartment 5 is adjusted while measuring the temperature of the upper surface of the object 26 to be frozen. Therefore, since the condition of the object 26 to be frozen can be checked and supercooled, water droplets can be reduced.

Referring to FIG. 6 , the structure of the spacer member 20 will be described in detail. A plurality of communication ports 21 are formed in a predetermined shape and arrangement so as to uniformly cool the inside of upper freezer compartment 5 . Here, the elongated communication port is formed in the width direction.

The second air blower 23 is an axial flow air blower including a rotary fan 23 a (for example, a propeller fan), a casing 23 b, and a fan motor not shown. In the second air blower 23 , the casing 23 b is fixed to the upper surface side of the partition member 20 . Here, cold air constituted by the air passage 46 from the cooler and the air passage 43 from the upper freezer enters the fan 23a.

The rear portion of the spacer member 20, that is, the rear side is formed with an inclined surface 20a that is gradually inclined downward toward the rear. And the opening part 22 is formed in the inclined surface 20a, and the 2nd air blower 23 is arrange|positioned in the opening part 22. As shown in FIG.

In addition, since the second air blower 23 is arranged on the inclined surface 20a, the rotation axis of the fan 23a is not vertical but inclined in the front-rear direction of the refrigeration equipment 1. Specifically, the second air blower 23 is disposed with its blowing direction (the direction of the rotation shaft on the blowing side of the fan 23 a ) directed downward and inclined forward.
