[0014]
[Effect of the embodiment]
Next, the operation of the hot-air storage according to the embodiment will be described. As shown in FIG. 1 or FIG. 2, in the hot-air storage 10 of the present embodiment, two storage chambers 31, via the air flow passage 40 are provided inside the heat insulating box 13 (inner box 12). 35 is defined in parallel in the width direction (left and right direction), and the blower 15 is disposed in each upper space 27a defined above the storage chambers 31 and 35, corresponding to the storage chambers 31 and 35, respectively. Is done. A partition plate for partitioning the upper spaces 27a, 27a in the width direction (left-right direction) between the adjacent blowers 15, 15 and guiding the hot air sent out by the blowers 15, 15 to the air flow passage 40. 25 is provided. The hot air circulation in the left storage chamber 31 will be described. When the blower 15 is operated, the air in the left storage chamber 31 is sucked into the upper space 27a from the suction port 41 provided in the top plate 32, Heated in contact with the heater 16. Of the obtained hot air, the hot air flowing to the left flows down the side space 27b along the left side surface 12b of the inner box 12. On the other hand, when the hot air flowing on the right side reaches the partition plate 25, it flows down the first passage 40 a (air flow passage 40) along the partition plate 25. And the hot air which flows down the said side part space 27b and the 1st channel | path 40a blows out in the said left storage chamber 31 from the said blower outlet 42, and performs disinfection and drying of tableware.
[0015]
Similarly, in the right storage chamber 35, when the blower 15 is operated, the air in the right storage chamber 35 is sucked into the upper space 27 a from the suction port 41 provided in the top plate 36 and contacts the heater 16. And heated. Of the obtained hot air, the hot air flowing on the right side flows down the side space 27b along the right side surface 12b of the inner box 12. On the other hand, when the hot air flowing on the left side reaches the partition plate 25, it flows down the second passage 40 b (air flow passage 40) along the partition plate 25. The hot air flowing down the side space 27b and the second passage 40b is blown into the right storage chamber 35 from the outlet 42 to disinfect and dry the dishes.
[0016]
In this way, the respective blowers 15 and 15 are operated, and the hot air moving from the upper spaces 27a and 27a of the storage chambers 31 and 35 to the air flow passage 40 on the partition plate 25 side flows stably without interfering with each other. Efficient air circulation can be performed. Further, even if the machine width is large, the box body is partitioned by the partition plate 25 and the blower 15 is disposed corresponding to each of the storage chambers 31 and 35. Therefore, sufficient air circulation in each of the storage chambers 31 and 35 is achieved. While ensuring the volume, the variation in the air volume can be reduced. Therefore, the tableware 20b stored in each of the storage chambers 31 and 35 can be efficiently dried and disinfected. In addition, since the partition plate 25 is disposed between the reinforcing members 28 and 28 that have not been effectively used conventionally, the air flow passage 40 (the first passage 40a and the second passage 40b) through which the hot air flows is formed. There is no fear that the space for storing the tableware 20b will decrease. Furthermore, by providing the partition plate 25, the strength of the hot-air storage 10 can be improved.
[0017]
In addition, since the blower 15 is disposed at a substantially central position (a position away from the reinforcing members 28 and 28) of the storage chambers 31 and 35, the member defining the suction port 41, the blower 15 and the like can be repaired. Inspection can be performed easily and workability is improved. Further, since the required gap 26 is provided between the lower edge of the partition plate 25 and the inner bottom surface 13a of the heat insulating box 13, the number of parts for assembling the partition plate 25 to the inner bottom surface 13a increases. In addition, sealing work and the like do not increase.
[0018]
Moreover, even if it is a conventional hot-air storage, if a plurality of units are used in parallel, efficient air circulation in the storage room and variation in the air volume can be prevented. However, in this case, on the side where the hot-air storage is close, the side wall portion of the heat insulation box overlaps twice, and there is a problem that the width dimension becomes large. However, according to the hot-air storage 10 according to the embodiment, since the plurality of storage chambers 31 and 35 are defined in the single heat insulating box 13, the hot-air storage is conventional. It is possible to secure the same amount of tableware storage as when the two are installed in parallel, and the horizontal width of the apparatus main body is reduced to allow installation in a narrow place. Furthermore, since there is no waste that the side wall part of the heat insulation box 13 overlaps, manufacturing cost can be reduced.
[0019]
[Another example]
In the above-described embodiment, when the inside of the heat insulation box of the hot air storage is defined in the left and right storage chambers, the partition plate is extended to the vicinity of the inner bottom surface of the box. It is not something that can be done. For example, as shown in FIG. 3, the left and right storage chambers 31 and 35 are defined in the heat insulating box 13 with the same configuration as the above-described embodiment, and only the upper spaces 27a and 27a above the storage chambers 31 and 35 are formed. The partition plate 25 is disposed so as to define left and right. At this time, the air flow passage 40 defined by the right side plate 34 of the left storage chamber 31 and the left side plate 38 of the right storage chamber 35 communicates with the upper spaces 27a and 27a of the storage chambers 31 and 35, respectively. Yes. Other configurations are the same as those in the above-described embodiment.
[0020]
Even in the hot-air storage configured as described above, the hot air from the blowers 15 and 15 disposed in the upper spaces 27a and 27a of the left and right storage chambers 31 and 35 is received by the partition as in the above-described embodiment. By reaching the plate 25, it is guided to the air flow passage 40 and has the same effect as the above-described embodiment. Furthermore, since only the upper spaces 27a and 27a are partitioned by the partition plate 25, the member cost can be reduced.
[0021]
Furthermore, as shown in FIG. 4, the lower end edge of the partition plate 25 may be extended to the inner bottom surface 13 a of the heat insulating box 13. In this case, water in each of the storage chambers 31 and 35 can be discharged by drilling the drain holes 29 in the bottom wall of the heat insulation box 13 corresponding to each of the storage chambers 31 and 35 in the heat insulation box 13. The air flow passage 40 defined by the right side plate 34 of the left storage chamber 31 and the left side plate 38 of the right storage chamber 35 is completely separated by the partition plate 25 by the first passage 40a and the second passage 40b. As in the above-described embodiment, stable air circulation in the heat insulating box 13 can be performed, and the tableware can be efficiently dried and disinfected.
[0022]
In the embodiment, two storage chambers are defined in the heat insulating box, but the present invention is not limited to this, and three or more storage chambers can be defined. Furthermore, in the present invention, in the box-shaped main body, a plurality of storage chambers are defined in parallel in the width direction via a passage through which hot air flows, and the blowers are respectively disposed on the upper portions of the storage chambers. What is necessary is just to comprise so that the partition plate which can guide the air sent out from each said air blower to the channel | path defined between both adjacent storage chambers may be formed between adjacent air blowers, and various design changes are possible. is there.
[0023]
【The invention's effect】
As described above, according to the hot-air storage according to the present invention, a plurality of storage chambers are defined in parallel in the width direction through a passage through which hot air flows in the box-shaped main body, and A blower is disposed in each of the upper spaces defined on the upper side, and a partition plate capable of guiding the air sent out from each blower to the passage between the adjacent storage chambers is provided. Thereby, the air sent out from each blower does not interfere with each other, and stable air circulation can be performed even in a hot-air storage with a large lateral width, and variation in the air volume can be reduced. Therefore, it is possible to efficiently disinfect and dry the tableware stored in each storage room. Moreover, if the partition plate and the passage are formed in the space between the reinforcing members that have not been effectively used in the past, the storage space for the tableware will not decrease. Furthermore, while ensuring a storage space equivalent to the case where a plurality of hot-air storages are arranged in parallel, the lateral width of the apparatus can be reduced, saving space and reducing manufacturing costs.
