Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, in recent years, there has been a demand for refrigerated storage facilities equipped with a large number of the aforementioned storage containers, for example, to increase the variety of pizza toppings. In such cases, multiple storage containers are arranged in the width direction (left-right direction when viewed from the front) and depth direction of the refrigerated storage facility. When a large number of storage containers are provided, it is difficult to adequately distribute the cold air inside the facility using the internal ducts and airflow guides described in Patent Document 1, and stored items in containers located in positions where cold air is not easily supplied tend to be undercooked.

[0006] This technology was developed in consideration of the circumstances described above, and aims to reliably suppress insufficient cooling of the storage containers that are positioned to cover the top opening of the storage unit. [Means for solving the problem]

[0007] To solve the above problems, the cooling storage facility disclosed in this application has the following configuration.

[0008] (1) A storage container body having a front opening and a top opening, comprising a storage chamber through the front opening into which stored items are contained, and a cooler chamber for housing a cooler, A plurality of storage containers are provided above the main body of the storage unit so as to cover the top opening, A circulating fan circulates the air inside the storage chamber by drawing air in from the storage chamber, passing it through the inside of the cooler, and blowing out the air cooled by the cooler. A cold air duct is provided in the storage unit body between the storage chamber and the top opening, and defines a flow path through which cold air blown out by the circulation fan flows in and heads toward the plurality of storage containers, A cooling storage facility comprising: a plurality of auxiliary fans, each provided between the cold air duct and the plurality of storage containers, which change the airflow direction so that a portion of the cold air flowing into the cold air duct is directed toward the plurality of storage containers, the plurality of auxiliary fans provided at intervals along the extending direction of the flow path.

[0009] Furthermore, the above-described cooling storage facility can be configured in various ways as shown below.

Embodiments for Carrying Out the Invention

[0015] Embodiments of the present technology will be described based on FIGS. 1 to 9. In some parts of the drawings, directions are indicated using the signs F, B, L, R, U, D, which represent the front side (front), back side (rear), left side, right side, upper side, and lower side when viewing the cooling storage 100 from the front, respectively.

[0016] As shown in FIG. 1, the cooling storage 10 is generally horizontally long and substantially rectangular parallelepiped in shape, and is a commercial refrigerator in which horizontal refrigerators 10L and 10R (an example of a cooling storage), which are of the three-door type and the two-door type, are connected in the left-right direction. The cooling storage 10 may be composed of only one of the horizontal refrigerators 10L and 10R, or may be composed of three or more connected horizontal refrigerators.

[0017] The two horizontal refrigerators 10L and 10R have similar structures. As shown in FIGS. 1 to 3, each includes a storage body 11L, 11R, heat insulation doors 12L, 12R, storage rooms 13L, 13R that occupy most of the internal space of the storage bodies 11L, 11R, cooler rooms 14L, 14R provided on the sides of the storage rooms 13L, 13R, machine rooms 15L, 15R provided on the sides and below the cooler rooms 14L, 14R, a plurality of storage containers (so-called hotel pans) 80L, 80R, installation bases 70L, 70R for the storage containers 80L, 80R, and cooling devices 20L, 20R for cooling the storage rooms 13L, 13R and the storage containers 80L, 80R. The cooling devices 20L, 20R are housed in the cooler rooms 14L, 14R and the machine rooms 15L, 15R.

[0018] The storage units 11L and 11R are insulated boxes having front openings 11L1 and 11R1, and top openings 11L2 and 11R2. The insulated doors 12L and 12R are swing-type doors that can open and close the front openings 11L1 and 11R1 of the storage units 11L and 11R. As shown in Figure 3, the top openings 11L2 and 11R2 are provided on the rear (back) side of the top surface of the storage units 11L and 11R, and in this embodiment they are horizontally elongated rectangular in shape. The portion of the top surface of the storage units 11L and 11R in front of the top openings 11L2 and 11R2 is closed off by ceiling walls 11L3 and 11R3.

[0019] The main difference between the two horizontal refrigerators, 10L and 10R, is that the left-hand horizontal refrigerator 10L is larger in width than the right-hand horizontal refrigerator 10R. Consequently, the left-hand horizontal refrigerator 10L has a larger number of storage compartments (13L), insulated doors (12L), space for multiple storage containers (80L), and a larger mounting base (70L) compared to the right-hand horizontal refrigerator 10R. Additionally, the left-hand horizontal refrigerator 10L does not have an 80L storage container above its machine room (15L), whereas the right-hand horizontal refrigerator 10R has an 80R storage container above its machine room (15R).

[0020] The two horizontal refrigerators, 10L and 10R, have the same basic structure and are formed symmetrically. Therefore, the horizontal refrigerator 10R on the right will be described in detail below, and for the horizontal refrigerator 10L on the left, redundant explanations of identical components will be omitted, the same reference numerals will be used in the illustrations, and only the differences will be explained.

[0021] Multiple storage containers 80R are installed on a mounting base 70R and positioned above the storage unit body 11R. The mounting base 70R has a sloping rear section and a flat front section. As shown in Figure 4, an installation opening 71A is formed in the sloping rear section 71 of the mounting base 70R into which the storage containers 80R are inserted. The installation opening 71A overlaps with the top opening 11R2 of the storage unit body 11R. As shown in Figure 6, the storage containers 80R are detachably positioned to cover the top opening 11R2 of the storage unit body 11R.

[0022] The flat plate portion 72 at the front of the mounting base 70R is a portion that can be used as a cooking workspace. The flat plate portion 72 constitutes the upper surface of the ceiling wall 11R3 of the storage unit body 11R. A tray 73 is placed on the flat plate portion 72 according to this embodiment. A total of four trays 73 are placed across the left and right horizontal refrigerators 10L, 10R, but they do not have to be provided. The horizontal refrigerator 10R is used, for example, to take out pizza topping ingredients stored in the storage container 80R and to perform the topping work on pizza dough placed on multiple rod-shaped members provided on the tray 73.

[0023] The containment container 80R stores the contents in a cooled state, separate from the storage chamber 13R. The cooling temperature of the containment container 80R is, for example, in the range of 1°C to 5°C. The containment container 80R is box-shaped with an open top and is arranged in multiples in the left-right and front-back directions. The number and size of each containment container 80R can be changed as appropriate according to the specifications. A lid is provided on the top opening of the containment container 80R, but it is omitted in the illustration to clearly show the containment container 80R.

[0024] The planar size of the storage container 80R according to this embodiment varies in several ways to suit the type of stored goods. As shown in Figure 4, the depth of the storage container 80R is preferably smaller for the rear storage container 80R when adjacent to each other in the front-to-back direction. The depth of the rear storage container 80R is, for example, in the range of 100 mm to 150 mm. Since the worker stands in front of the insulated door 12R, it is difficult to reach the rear storage container 80R. Therefore, by reducing the depth of the rear storage container 80R, it becomes easier to reach their bottom surfaces 80R1.

[0025] Furthermore, while the depth of the containment containers 80R is almost the same between adjacent containment containers 80R in the left-right direction, the depth of the containment container 80R located near the second auxiliary fan 65, which will be described later, is smaller in order to secure space for the second auxiliary fan 65 (see Figure 9).

[0026] The horizontal refrigerator 10R is equipped with a first cold air duct 30, a second cold air duct 40, a third cold air duct 67, a circulation fan 35, a cover member 43, a first guide member 50, a second guide member 55, a third guide member 68, a first auxiliary fan 60, and a second auxiliary fan 65, in order to circulate the air inside the storage compartment body 11R (hereinafter, "inside the storage compartment body 11R" may be referred to as "inside the compartment") and cool the storage chamber 13R and the storage container 80R with a cooling device 20R. Each of these components will be described in detail below.

[0027] As shown in Figure 2, the first cold air duct 30 is installed so as to extend vertically within the storage area, dividing the storage area into left and right sections. The portion of the storage area to the left of the first cold air duct 30 overlaps with the insulated door 12R in the front-to-back direction, and becomes accessible through the front opening 11R1 when the insulated door 12R is opened. The majority of this portion is the storage room 13R, into which stored goods are placed via the front opening 11R1.

[0028] The portion of the storage unit to the right of the first cold air duct 30 is a cooler room 14R, which houses the cooler 22 and the circulation fan 35. The first cold air duct 30 has an intake port 30A for drawing air from the storage room 13R into the cooler room 14R, and a first outlet port 30B located above the intake port 30A for blowing out the cold air from the cooler room 14R.

[0029] The cooler 22 is, for example, a fin-and-tube type heat exchanger, which cools the air passing through it by vaporizing the incoming refrigerant and using the heat of vaporization. The machine room 15R houses part of the cooling system 20R (compressor 24, condenser, and condenser fan, etc.) as well as control devices, etc. The cooling system 20 is equipped with a compressor 24, a condenser, an expansion valve (cavilary tube), and a cooler 22, and these are connected in this order by refrigerant pipes, circulating the refrigerant and thus forming a known refrigeration circuit (refrigeration cycle).

[0030] The circulation fan 35 draws air from the storage chamber 13R through the intake port 30A and passes it through the inside of the cooler 22. The circulation fan 35 also circulates the air in the storage chamber 13R so that the air cooled by the cooler 22 (cold air) is blown out from the first outlet port 30B.

[0031] As shown in Figures 2 and 4, the second cold air duct 40 partitions the left side of the storage chamber from the first cold air duct 30, both vertically and horizontally. The second cold air duct 40 extends horizontally and vertically between the storage chamber 13R and the top opening 11R2 (ceiling wall 11L3).

[0032] The portion below the second cold air duct 40 is the storage room 13R. The portion above the second cold air duct 40 is a flow path 45 into which cold air blown out from the first outlet 30B by the circulation fan 35 flows. The flow path 45 extends in the left-right direction so that the cold air flowing in from the first outlet 30B flows from right to left. The second cold air duct 40 defines (constitutes) the lower surface of the flow path 45.

[0033] As shown in Figure 5, the second cooling duct 40 is a rectangular plate shape extending in the left-right direction. A cover member 43 is attached to the front side (front opening 11R1 side) of the second cooling duct 40 from the front, and a first guide member 50 is attached to the rear side from above. The second cooling duct 40 has an insertion port 40B into which the lower end of the first guide member 50 is inserted, and a second outlet port 40C.

[0034] The cover member 43 is a member that defines the front surface of the flow path 45 and, together with the second cooling duct 40 and the ceiling wall 11L3, forms the flow path 45. A riser portion 40A for attaching the cover member 43 is provided at the front end of the second cooling duct 40. The cover member 43 is detachably attached to the riser portion 40A by screw fastening. In this embodiment, two cover members 43 are provided in the horizontal refrigerator 10R, but the number is not limited.

[0035] By making the cover member 43 detachable, the cover member 43 can be easily removed when the insulated door 12R is opened. As shown by the white arrows in Figure 6, if stored items fall when attaching or detaching the storage container 80R, they may pass through the gaps of the first guide member 50 and the first auxiliary fan 60 (described later) and accumulate on the second cold air duct 40. By removing the cover member 43, the second cooling duct 40 can be easily cleaned, and the first auxiliary fan 60 (described later) can be easily removed from the mounting panel 61 for inspection and replacement.

[0036] The first guide member 50 has a main body portion 51 that inclins upward as it moves backward, and side portions 52 that protrude downward from both the left and right ends of the main body portion 51. The first guide member 50 can be easily attached to and detached from the second cold air duct 40 by inserting the projections at the lower ends of the side portions 52 into and out of the insertion opening 40B of the second cold air duct 40. By removing the containment container 80R and pulling the first guide member 50 upward, the first guide member 50 can be easily removed for cleaning and other purposes.

[0037] As shown in Figure 4, the main body 51 of the first guide member 50 guides the flow path 45 to supply the cool air, whose direction has been changed by the first auxiliary fan 60 (described later), to the containment container 80R. The cool air hits the bottom surface 80R1 and the sides 80R2 of the containment container 80R, thereby cooling the containment container 80R and the contents stored inside it.

[0038] A bent portion 51A is formed at the rear end (the downstream end in the cold air flow direction) of the main body 51 of the first guide member 50. The bent portion 51A has a larger angle of inclination with respect to the horizontal than the main body 51 and is bent upward. By providing the bent portion 51A, the cold air guided along the main body 51 can more easily reach the containment container 80R located at the rear. As previously described, it is preferable that the depth of the rear containment container 80R be made small so that it can be easily reached by the worker's hand, but in that case, it becomes difficult to supply cold air to the rear containment container 80R. By providing the bent portion 51A, cold air can be reliably supplied to the rear containment container 80R, which is difficult to reach with cold air. As a result, insufficient cooling of the containment container 80R can be more reliably suppressed.

[0039] The first auxiliary fan 60 and the second auxiliary fan 65 are installed between the second cold air duct 40 and the storage container 80R, as shown in Figures 4 and 9. The second auxiliary fan 65 changes the airflow direction so that a portion of the cold air flowing into the second cold air duct 40 is directed towards the storage container 80R located above the machine room 15R. The first auxiliary fan 60 changes the airflow direction so that a portion of the cold air flowing into the second cold air duct 40 is directed towards the storage container 80R located in a location other than above the machine room 15R. Note that the horizontal refrigerator 10L on the left does not have a storage container 80L located above the machine room 15L, and therefore does not have a second auxiliary fan 65 (see Figure 3).

[0040] As shown in Figures 2 and 3, multiple first auxiliary fans 60 are arranged at intervals along the extending direction (left-right direction) of the flow path 45 (second cooling duct 40). In this embodiment, the right-side horizontal refrigerator 10R is provided with two first auxiliary fans 60, and the left-side horizontal refrigerator 10L is provided with four first auxiliary fans 60. As shown in Figure 4, the first auxiliary fans 60 are mounted on an inclined mounting panel 61 provided in front of the first guide member 50 on the second cooling duct 40.

[0041] As shown in Figures 4 and 8, the first auxiliary fan 60 draws in a portion of the cold air flowing along the extension direction (left-right direction) of the flow path 45 (second cooling duct 40) from the front and blows it diagonally backward toward the main body 51 of the first guide member 50, thereby changing the direction of the cold air. As a result, a portion of the cold air in the flow path 45 is drawn into the first auxiliary fan 60, flows onto the first guide member 50, and flows along the main body 51 of the first guide member 50. The cold air then moves upward along the bent portion 51A at the rear end of the main body 51, then descends after hitting the bottom surface 80R1 of the containment container 80R or the wall of the mounting base 70R, and flows into the storage chamber 13R from the second outlet 40C of the second cooling duct 40.

[0042] As shown in Figures 7 and 8, the second auxiliary fan 65 is located closer to the first outlet 30B than the first auxiliary fan 60 in the left-right direction. The second auxiliary fan 65 is positioned above the third cold air duct 67, which is installed on the first cooling duct 30.

[0043] The third cold air duct 67 is box-shaped and has an upper opening 67A, a front opening 67B, and ventilation openings 67C on the left, right, and rear sides. The second auxiliary fan 65 is placed on top of the third cold air duct 67 so as to cover the upper opening 67A. As shown in Figure 8, the side ventilation openings 67C partially overlap with the first outlet 30B in the front-to-back direction. As a result, the cold air from the first outlet 30B flows into the third cold air duct 67 not only from the front opening 67B but also from the ventilation opening 67C on the right side, passes through the upper opening 67A, and is drawn into the second auxiliary fan 65.

[0044] The third guide member 68 is a plate-shaped member provided between the first outlet 30B and the third cold air duct 67. The third guide member 68 guides the cold air flowing into the flow path 45 from the first outlet 30B into the third cold air duct 67. By attaching or detaching the third guide member 68, or by changing the angle of its main surface, the flow rate of cold air drawn into the second auxiliary fan 65 through the third cold air duct 67, and consequently the flow rate of cold air supplied to the containment container 80R located above the machine room 15R, can be easily adjusted.

[0045] The second guide member 55 performs the same function as the first guide member 50. The main body 56 of the second guide member 55 guides the cold air, which flows into the flow path 45 and whose airflow direction has been changed by the second auxiliary fan 65, to be supplied to the containment container 80R. The inclination angle of the main body 56 of the second guide member 55 is larger than that of the main body 51 of the first guide member 50, as shown in Figures 7 and 9.

[0046] As previously described, the depth of the containment container 80R located near the second auxiliary fan 65 is made small in order to secure space for the second auxiliary fan 65. Therefore, by increasing the inclination angle of the main body portion 56 of the second guide member 55, cold air can be supplied more uniformly and reliably even to the containment container 80R, which has a small depth. The inclination angles of the main body portions 51 and 56 of the guide members 50 and 55 are appropriately adjusted according to the depth of the containment container 80R and the positional relationship between the containment container 80R and the auxiliary fans 60 and 65, thereby allowing the containment container 80R to be cooled effectively.

[0047] According to the above configuration, the air in the storage chamber 13R is drawn in from the intake port 30A by the circulation fan 35, cooled by passing through the cooler 22, and blown out into the flow path 45 from the first outlet port 30B. The cold air that flows into the flow path 45 flows from right to left along the flow path 45, and a portion of it is drawn in by the first auxiliary fan 60.

[0048] The flow path 45 is a long, straight line in the left-right direction, and no other components are positioned in front of the first auxiliary fan 60 within the space that constitutes the flow path 45. As a result, the cold air flowing in from the first outlet 30B reaches even the parts far from the first outlet 30B along the flow path 45. The first auxiliary fan 60 is also installed to change the direction of the cold air from left-right to diagonally rearward, and the angle of change in air direction is large (almost right angle when viewed from above). Therefore, the cold air flowing into the flow path 45 from the first outlet 30B is not excessively sucked in by the first auxiliary fan 60 located closer to the first outlet 30B, and is also appropriately sucked in by the first auxiliary fan 60 located further away from the first outlet 30B. In this way, each first auxiliary fan 60 sucks in cold air at an appropriate flow rate, and the cold air is evenly blown out toward the multiple containment containers 80.

[0049] The cold air drawn into the first auxiliary fan 60 flows along the main body 51 of the first guide member 50 and comes into contact with the bottom surface 80R1 and the side surface 80R2 of the containment container 80R. After passing near the containment container 80R, the cold air descends and flows into the storage chamber 13R from the second outlet 40C of the second cooling duct 40.

[0050] Furthermore, some of the cold air that flows into the flow path 45 passes through the third cold air duct 67 and is drawn into the second auxiliary fan 65, where it flows along the main body 56 of the second guide member 55 and comes into contact with the bottom surface 80R1 and side surface 80R2 of the containment container 80R located above the machine room 15R. The cold air that has passed near the containment container 80R then descends and flows into the storage room 13R from the second outlet 40C of the second cooling duct 40. In this way, the air in the storage room 13 is circulated, and cold air is supplied to the storage room 13R and the containment container 80.

[0051] As described above, the horizontal refrigerator 10R includes a second cold air duct 40 provided in the storage body 11R between the storage chamber 13R and the top opening 11R2, defining a flow path 45 through which cold air blown out by the circulation fan 35 flows into the storage chamber 13R, and a first auxiliary fan 60 provided between the second cold air duct 40 and the multiple storage containers 80R, which changes the airflow direction so that a portion of the cold air flowing into the second cold air duct 40 is directed towards the multiple storage containers 80R.

[0052] By providing the first auxiliary fan 60 in this manner, the direction of the cold air blown into the second cold air duct 40 can be changed so that it is directed towards the containment container 80R. This ensures that the cold air reliably hits the containment container 80R. Even when the space required for the containment container 80R is large and a large number of containment containers 80R are provided, insufficient cooling of the containment container 80R located in a position where cold air is difficult to supply (the rear side in this embodiment) can be reliably suppressed.

[0053] <Other Embodiments> This technology is not limited to the embodiments described above, and can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. For example, the following embodiments are also included in the technical scope of this technology.

In that case, the second auxiliary fan 65, the third cold air duct 67, the second guide member 55, and the third guide member 68 do not need to be provided. [Explanation of Symbols]
