The central portion of the upper space 14a communicates with the storage chamber 16 via a suction port 22a formed in the top plate 22. Further, the side spaces 14b and 14b extend downward from both side portions of the upper space 14a and communicate with the storage chamber 16 via a plurality of air outlets 24a formed in the side plates 24 and 24.

In the upper space 14a of the circulation path 14, a blower fan 28 is arranged at a position corresponding to the suction port 22a, and an electric heater 30 which is a heating device is arranged so as to orbit the blower fan 28. The blower fan 28 sucks the air in the storage chamber 16 from the suction port 22a into the upper space 14a, and brings the sucked air into contact with the electric heater 30. Therefore, the air sucked into the upper space 14a from the storage chamber 16 side by the operation of the blower fan 28 becomes hot air and flows into the side spaces 14b and 14b, and is blown out to the storage chamber 16 from the outlet 24a of the side plate 24.

That is, by closing the exhaust duct 32 and heating the stored object in a state where the moisture in the storage chamber 16 is not discharged to the outside, the stored object is disinfected. Further, by opening the damper 34 of the exhaust duct 32 and heating the stored object in a state where the moisture in the storage chamber 16 is discharged to the outside, the stored object is dried.

In the kitchen facility, a cooking preservation / serving method is used, in which cooked ingredients (cooking) are once cooled to a chilled state, served on tableware, and reheated at the timing of serving the cooking. In this case, it is desirable that the dishes are sufficiently cold when serving the dishes. On the other hand, in the disinfection storage 10 described above, there is a problem in that it takes time for the stored material after disinfection and drying to cool sufficiently, and cold tableware and the like cannot be prepared promptly. For example, if the door is fully opened and the air outside the refrigerator is taken into the storage chamber 16, the time until the stored items cool down can be shortened. Air from the outside will come into contact, causing hygiene problems. Considering such circumstances, it is preferable to provide a cooling device for cooling the inside of the refrigerator in the disinfection storage 10.

(Overall configuration of disinfection storage 10)
As described above, in the disinfection storage 10, a storage room 16 for storing stored items (articles) such as tableware to be disinfected and dried is defined inside (inside) the rectangular box-shaped housing 12. At the same time, a circulation path 14 connecting the suction port 22a and the air outlet 24a is defined. The disinfection storage 10 of the first embodiment carries a tableware cart (cart) on which the stored items are placed into the storage chamber 16 and disinfects the stored items on the tableware cart by operating the electric heater (heating device) 30. It is a so-called cart-in type disinfection storage that dries. The disinfection storage 10 is equipped with a freezing mechanism R having an evaporation pipe (cooling device) 36.

The refrigerating mechanism R has a compressor, a condenser, an expansion valve, etc., and an evaporator 36 as a cooling device connected in an annular shape by a refrigerant pipe, and as shown in FIG. 2, a large size other than the evaporator 36. A portion is arranged in the machine chamber 18. This refrigerating mechanism R includes a plurality of evaporators 36 (specifically, two), and each evaporator 36 has left and right sides of the upper space 14a (more specifically, the blower fan 28) of the circulation path 14. ). An electric heater 30 is provided on the outer peripheral side of the upper space 14a, and each evaporator 36 is located on the inner peripheral side of the electric heater 30.

As shown in FIG. 2, the upper space 14a of the circulation path 14 is defined between the top plate 22 of the storage chamber 16 and the first partition plate 51 extending in the left-right direction above the top plate 22. Further, the side spaces 14b and 14b of the circulation path 14 are defined between the side plates 24 and 24 of the storage chamber 16 and the second partition plate 52 extending in the vertical direction on the outer side thereof.

As shown in FIGS. 1 and 2, the housing 12 is provided with left and right side panels 50B and 50B constituting the left and right side surfaces of the housing 12. Each of the side panels 50B and 50B is composed of a lower panel 53 corresponding to the height position of the circulation path 14 and the storage chamber 16 and an upper panel 54 corresponding to the height position of the machine room 18, and the second partition plate 52.

(Air guide 60)
Here, the air guide 60 that guides the air from the blower fan 28 to the side space 14b will be described below with reference to FIGS. 2 to 4. As shown in FIG. 2, air guides 60 and 60 are provided on both sides of the circulation path 14 of the disinfection storage 10. Since the left and right air guides 60 and 60 have symmetrical shapes, the right air guide 60 (see FIGS. 3 and 4) will be mainly described, and the left air guide 60 will be omitted.

As shown in FIG. 2, the air guide 60 is a plate-shaped member long in the front-rear direction (see FIG. 4), and is arranged on both sides of the circulation path 14 (upper space 14a). The front-rear dimension of the air guide 60 is substantially equal to the front-rear dimension of the circulation path 14 (upper space 14a).

As shown in FIG. 3, the air guide 60 has an upper fixing portion 61 formed by bending the upper edge portion thereof, which is fixed to the side end side of the lower surface of the first partition plate 51 and has a lower edge portion. The lower fixing portion 62 formed by bending is fixed to the upper end side of the inner side surface of the second partition plate 52. The lower fixing portion 62 is positioned so as to sandwich the second partition plate 52 with the connecting frame 59. Then, the portion of the air guide 60 between the upper fixing portion 61 and the lower fixing portion 62 functions as a wind receiving portion 63 that receives the air sent from the blower fan 28 and guides it downward (side space 14b). ing. The wind receiving portion 63 is formed in an inclined shape that separates from the blower fan 28 as it approaches the lower end from the upper end thereof.

In the conventional disinfection storage 10 (without the air guide 60), the circulation path 14 is provided by the air from the blower fan 28 (the air cooled by contacting the evaporator 36 while moving in the upper space 14a) during the cooling operation. When the upper corner portion 15 (the portion composed of the side end portion of the first partition plate 51 and the upper end portion of the second partition plate 52) is cooled, the vicinity of the upper edge 53a of the lower panel 53 (first range A1). ) And the vicinity of the lower edge 54a (second range A2) of the upper panel 54 is likely to be cooled and dew condensation is likely to occur. On the other hand, in the disinfection storage 10 of the first embodiment, the air guide 60 covers the upper corner portion 15 of the circulation path 14 by the first partition plate 51 and the second partition plate 52, so that the air is sent from the blower fan 28. The air moving in the horizontal direction does not directly hit the upper corner portion 15 of the circulation path 14, and the temperature of the upper extending portion 55 of the lower panel 53 and the upper panel extending portion 57 of the upper panel 54 can be prevented from dropping. .. That is, it is possible to suppress the occurrence of dew condensation on the outer surface (particularly the first range A1 and the second range A2) of the side panel 50B (lower panel 53 and upper panel 54). By using the air guide 60, which is inexpensive and easy to install, the cost of parts can be suppressed and the installation work can be simple.

(Cord heater 65)
Next, the cord heater 65 as a dew condensation prevention heater will be described below with reference to FIGS. 3 and 5. As described above, when the inside of the disinfection storage 10 is cooled according to the cooling operation, the upper corner portion 15 of the circulation path 14 is cooled, so that the outer surface of the side panel 50B (particularly the first range A1 and the like) The second range A2) may also cool and dew condensation may occur. Therefore, in the first embodiment, dew condensation prevention heaters (cord heater 65, which will be described later) are installed on the inner surface side of the left and right side panels 50B, respectively.

The cord heater 65 is a linear electric heater that can be bent and deformed, and extends in the front-rear direction along the upper edge 53a of the lower panel 53 (along the upper extending portion 55) (see FIG. 5). ). Specifically, the cord heater 65 is attached to the upper edge of the inner surface of the lower panel 53 (the surface facing the second partition plate 52) (see FIG. 3), and the upper horizontal portion 66 and the lower horizontal portion 66. A portion 67 and a bent portion 68 connecting the left ends of these horizontal portions 66 and 67 are formed. The horizontal portions 66 and 67 extend to the front side of the front edge of the upper panel 54, and the bent portion 68 is located below the front panel 50A covering the front surface of the machine room 18.

That is, in the disinfection storage 10 of the first embodiment, the cord heater 65, which is a linear dew condensation prevention heater that can be bent and deformed, has an upper edge portion of the inner surface of the lower panel (the surface facing the second partition plate 52). Therefore, the vicinity of the upper edge 53a (first range A1) of the lower panel 53 can be heated by heating the cord heater 65. Further, the heating of the cord heater 65 warms the upper extending portion 55 of the lower panel 53, and the heat conduction and heat radiation from the upper extending portion 55 warm the upper panel extending portion 57 of the upper panel 54. It is possible to suppress a temperature drop in the vicinity of the lower edge 54a (second range A2) of the upper panel 54, and to suppress the occurrence of dew condensation on the outer surfaces (first range A1 and second range A2) of the side panels 50B and 50B. can.

The cord heater 65 can also be installed on the connection frame 59 described above. However, in this case, since the connection frame 59 in contact with the second partition plate 52 is directly heated by the cord heater 65, the influence of the cooling operation on the cooling rate in the refrigerator may be large. That is, by installing the cord heater 65 on the lower panel 53, it becomes easier to maintain the cooling rate as compared with the case where it is installed on the connection frame 59.

(Structure related to the lower part of the lower panel 53)
As shown in FIG. 6A, the lower extending portion 56 extends horizontally from the lower edge 53b of the lower panel 53. The downward extending portion 56 is fixed to the side end portion of the lower wall 50C constituting the lower surface of the housing 12 by a screw N. Although only the lower extension portion 56 provided on the lower panel 53 on the right side is shown (see FIG. 6A), the lower extension portion 56 provided on the lower panel 53 on the left side has the same configuration. be.

Here, in the disinfection storage 10, the second partition plate 52 that covers the side space 14b of the circulation path 14 from the side and the lower panel 53 that covers the second partition plate 52 from the side at a close position are made of metal. It is reinforced by connecting with the reinforcing plate 70 of. The reinforcing plate 70 has a vertical plate portion 71 extending vertically along the lower portion of the outer surface 52a of the second partition plate 52 and a lower panel 53 extending horizontally from the lower edge of the vertical plate portion 71. It is composed of a horizontal plate portion 72 along the extending portion 56, the vertical plate portion 71 is fixed to the second partition plate 52 with screws N, and the horizontal plate portion 72 is below the lower wall 50C. It is fixed with a screw N together with the extending portion 56. That is, since the vertical plate portion 71 of the reinforcing plate 70 is in contact with the second partition plate 52 and the horizontal plate portion 72 of the reinforcing plate 70 is in contact with the lower extending portion 56 of the lower panel 53, the second section is cooled by the cooling operation. When the reinforcing plate 70 is cooled via the partition plate 52, the lower panel 53 is gradually cooled from the lower extending portion 56 due to the effect, and dew condensation is formed on the outer surface in the vicinity of the lower edge 53b (third range A3) of the lower panel 53. Can occur. Therefore, in the first embodiment, the contact area between the reinforcing plate 70 and the downward extending portion 56 is reduced by changing the shape of the reinforcing plate 70.

A plurality of the notches 73 are formed in the horizontal plate portion 72 to avoid the screw holes (fixing portions) 74 fixed to the downward extending portion 56, and are formed at positions between the plurality of screw holes 74. In Example 1, as shown in FIG. 6B, the notch 73 reached the position of the vertical plate portion 71 from the extending end of the horizontal plate portion 72, and the horizontal plate portion 72 was divided into a plurality of parts. It is in a state. On the other hand, the notch 73 may be recessed from the extending end of the horizontal plate portion 72 toward the base end side to an intermediate position.

As described above, in the disinfection storage 10 of the first embodiment, the horizontal plate 73 is provided in the horizontal plate portion 72 of the reinforcing plate 70 arranged between the second partition plate 52 and the lower panel 53. Since the contact area between the portion 72 and the lower panel 53 (lower extending portion 56) can be reduced, the temperature drop of the lower panel 53 due to the influence of the reinforcing plate 70 can be suppressed, and the vicinity of the lower edge 53b of the lower panel 53 (the first). It is possible to suppress the occurrence of dew condensation on the outer surface of the three ranges A3). Further, since the notch 73 is provided between the plurality of screw holes 74 in the horizontal plate portion 72, the number of screw holes 74 does not decrease due to the formation of the notch 73, and the reinforcing function of the reinforcing plate 70 is sufficient. Can be maintained.

Next, the disinfection storage 10 according to the second embodiment will be described below with reference to FIG. 7. The configuration different from that of the first embodiment will be basically described, and the same components as those of the first embodiment will be designated by the same reference numerals and detailed description thereof will be omitted.
