2. Description of the Related Art A hot-air storage that is disinfected and dried by contacting hot air with tableware and heating it is provided with a storage section inside a heat-insulating box body through a required space. A basket containing tableware is placed on the arranged shelves. The space includes an upper space defined above a top plate of the storage unit, a side space defined outside both side plates facing the width direction of the storage unit, and an outlet formed at a lower end of the both side spaces. And a bottom space that communicates through A suction port communicating with the upper space is formed in the top plate, and an impeller and a heater of a blower are arranged in the upper space.

[0003] In the hot-air storage, the air in the storage portion sucked into the upper space through the suction port is exchanged with a heater and heated by operating the blower, and the obtained hot air is transferred to the space in both sides. Let it flow down. Then, the hot air blown out to the bottom space from the outlets of the respective side spaces is introduced into the storage portion, raised, and forcedly circulated so as to return to the upper space from the suction opening, whereby the tableware stored in the storage portion. Is heated to disinfect and dry.

[0004]

Each of the side plates defining the side space is formed with a plurality of blow holes for blowing a part of the hot air flowing down the side space into the storage portion. A configuration is employed in which hot air coming into contact with tableware stored in a portion where hot air rising from a space is unlikely to come in contact with the hot air to efficiently perform disinfection and drying. However, due to the rotation direction of the blower, the hot air flowing into the side space from the upper space flows down to the portion corresponding to the front side in the rotation direction of the blower in the side space, and corresponds to the rear side in the rotation direction. Only a small amount of hot air is blown out of the blowing hole provided in the portion where the hot air is blown, and the amount of hot air contacting the tableware varies depending on the storage position. For this reason, the temperature and the degree of drying of the tableware stored in the storage unit vary, so that it takes a considerable time to heat all the tableware for disinfection and drying, and there is a drawback that the power consumption increases. In addition, it is pointed out that a large amount of hot air comes into contact with only some of the dishes and the dishes are damaged.

The air guide 54 extends over substantially the entire length of the side space 14b in the height direction. Instead of forming the plurality of blowout holes 24b in the side plate 24, one long hole (blowing hole) having a required length in the front-rear direction may be formed.

[0014]

According to the hot air storage 10 according to the embodiment constructed as described above, when the storage 10 is operated, the air in the storage section 16 is blown by the blower 32 into the suction port 28a. Then, the air is sucked into the upper space 14a and sent toward the heater 38, where it is heated by heat exchange to form hot air, and then flows into the both side spaces 14b, 14b. As shown in FIG. 1, part of the hot air that has flowed into each side space 14b is blown into the storage portion from a blowout hole 24b formed in the side plate 24 of the storage portion 16, and the baskets 20 located in the vicinity of the side plate (on both sides in the width direction). Is brought into contact with tableware stored in the basket 20). At this time, the air guide 54 provided on each side plate 24 causes the air guide 54 shown in FIGS.
As shown in FIG.
It is regulated that the hot air flows down in the direction of rotation in the front in the rotation direction, so that the hot air blows out from the outlets 24b substantially uniformly into the storage portion.

The hot air blown down the side spaces 14b, 14b and blown out from the outlets 26, 26 to the bottom space 14c collides with the inner bottom surface of the heat insulating box 12 and flows toward the center in the width direction. Be deflected. At this time, the guide portion 24a of the side plate 24 defining the blowout port 26 allows the blowout port 2
A portion of the hot air blown out from 6 is guided by the guide plate 24a and flows obliquely into the storage room. That is, the outlet 26
The hot air blown out from is diffused not only in the flow toward the center in the width direction along the inner bottom surface but also in each direction. This allows
Hot air also flows near the inside of the side plate 24, and the tableware stored near the side plate 24 can be heated and disinfected and dried in a short time. In particular, the hot air directly contacts the tableware stored at the lower end portions on both sides of the storage section 16 and disinfection and drying do not become incomplete.

Both hot air blown out from the two outlets 26, 26 and flowing toward the center of the bottom space 14c
The hot air efficiently comes into contact with the tableware accommodated in the basket 20 placed in the center of the shelf 18 and is heated, whereby disinfection and drying are performed. Then, the hot air that has heated the tableware returns to the upper space 14a from the suction port 28a.
And the circulation described above is repeated.

Since the air guide 54 is provided in the side space 14b as in the embodiment, the hot air blows out from the outlets 24b formed in the side plate 24 substantially uniformly into the storage portion. There is no variation in the temperature, degree of drying, etc. depending on the storage position of the tableware
All dishes can be disinfected and dried uniformly and quickly. In other words, it is possible to eliminate the occurrence of places where the disinfection and drying are incomplete in the storage section, so that no water remains on the tableware after disinfection. Further, for example, even in the case where a plurality of baskets 20 are arranged in front and rear in the depth direction of the storage section 16, the dishes stored in all the baskets 20 can be uniformly disinfected and dried. Furthermore, it is possible to suppress damage due to a large amount of hot air coming into contact with only specific dishes,
The life of the tableware can be prevented from being shortened. By arranging the air guide 54 on the side plate 24 as in the embodiment,
The strength of the side plate 24 is improved, the plate thickness can be reduced, and the cost can be reduced.

Further, in the embodiment, since the motor 34 of the blower 32 housed in the machine room 46 is surrounded by the partition plate 48, the through-hole 30a of the ceiling 30 through which the output shaft 34a of the motor 34 is inserted. It is possible to prevent the hot air flowing into the machine room 46 from directly contacting the electrical box 40 and reduce the thermal load on the electric components housed in the box. Furthermore,
The hot air guided by the partition plate 48 is
Top panel 50 and rear panel 52 exhaust port 50
Since the heat is efficiently discharged to the outside from the a and 52a, the heat can be prevented from being trapped in the machine room 46, and the heat load of the solenoid provided in the exhaust duct 42 can be reduced.

In the embodiment, the case where one air guide is arranged has been described. However, a plurality of air guides are arranged in parallel according to the length dimension of the side space in the front-rear direction (depth direction). Is also good. When a plurality of air guides are provided, it is possible to adopt a configuration in which the lengths (up and down dimensions) of the respective guides are set to be different from each other, so that the amount of hot air blown out from all the blowout holes is made uniform. . The air guide may be provided on the wall surface of the heat insulating box, or may be provided on both the wall surface and the side plate. Furthermore, the number of shelves and the number of baskets placed on the shelves in the width direction or the depth direction are not limited to the embodiments.

[0020]

As described above, in the hot-air storage according to the present invention, by providing the air guide in the side space, the hot air can be blown into the storage part from all the blowing holes formed in the side plate substantially uniformly. The tableware stored in the storage unit can be disinfected and dried by heating all the tableware uniformly and in a short time without causing variations in the temperature, the degree of drying, and the like depending on the storage position. Therefore, even when a plurality of baskets are arranged before and after in the depth direction of the storage section, the tableware stored in all the baskets can be uniformly disinfected and dried. In addition, it is possible to prevent the life of the tableware from being shortened without being damaged by a large amount of hot air coming into contact with only the specific tableware.

Further, since all the dishes can be heated and disinfected and dried in a short time, the operation time of the storage can be shortened, the power consumption can be reduced, and a blower or a heater having a small capacity can be adopted. By arranging the air duct on the side plate that defines the side space, the duct also functions as a reinforcing material, and the strength of the side plate is improved. Has the advantage of being able to reduce
