Reference numeral 25 denotes a door of the oven 15, and a predetermined operation switch is provided above the door 25.

On the other hand, the showcase 5 comprises an outer case 2 and a partition plate 3 having a substantially U-shaped cross section provided at an upper portion in the outer case 2.
A display room 7 having an opening 6 on the front surface is configured.

The partition plate 3 is provided inside the outer case 2 with a space therebetween, and between the back surface 3A and the top surface 3B and the outer case 2 is a series of main plates extending from the back surface 3A to the outside of the top surface 3B. A duct 8 is configured. A machine room 9 is formed in the outer case 2 below the partition plate 3, and a front surface of the machine room 9 is closed by a panel 11 so as to be openable and closable.

The lower end of the main duct 8 on the rear side of the back surface 3A of the partition plate 3 communicates with the inside of the machine room 9, and the top surface 3B
An outlet 12 is formed at the front end of the main duct 8 on the upper side of
It is open to the lower opening 6. In addition, a honeycomb material 13 for rectification is mounted in the outlet 12. Further, the corner of the outer case 2 where the main duct 8 is bent from the rear side of the rear surface 3A to the upper side of the top surface 3B is curved at a predetermined curvature to form a curved portion 2A.

In the display room 7, shelves 16, 16 are vertically arranged in two stages. The interior of each shelf 16 is hollow, and an in-shelf duct 17 is formed therein.
The rear end 7 penetrates through the back surface 3A of the partition plate 3 and communicates with the main duct 8. A guide member 18 is attached to the upper edge of the rear end opening of the duct 17 in the shelf, the guide member 18 projecting toward the main duct 8 while its tip is lowered. The upper guide member 18 projects to the main duct 8 side larger than the lower guide member 18.

Furthermore, an outlet 19 is formed at the front end of the in-shelf duct 17 of the upper shelf 16, and an outlet 21 is formed at the front end of the in-shelf duct 17 of the lower shelf 16. The opening 6 is open toward the opening 6. A honeycomb material 13 for rectification is also mounted in the outlets 19 and 21.

In this case, the shelf 1 above the outlets 19 and 21
The corner at the front end of the upper surface 6 is curved so as to prevent or suppress the turbulence of the air curtain descending from above as described later. The outlet 12 is directed toward the front of the shelf 16 immediately below, that is, toward the outside of the outlet 19, and the outlet 19 is directed to the front of the shelf 16 immediately below,
That is, it is directed toward the outside of the outlet 21.

Further, on the upper surface of each shelf 16 and on the bottom surface of the display room 7 (the bottom surface 3C of the partition plate 3), an in-compartment heater 23 composed of an electric heater is mounted. Discharge ports 24 communicating the main duct 8 and the display room 7 are formed on the back surface 3A located on the upper back of each space in the display room 7 to be partitioned.

On the other hand, in the machine room 9 at a position corresponding to a position below the main duct 8, a suction type blower 26 is mounted by a fan casing 27.
The HEPA filter 28 is disposed on the suction side of the pump 6. Further, suction ports 29, 29 are formed above and below the panel 11 and communicate with the inside of the machine room 9.
A pre-filter 31 coarser than the HEPA filter is attached inside 9.

Further, a suction port 32 is also formed at the front end of the bottom surface 3C of the partition plate 3 serving as a lower edge of the opening 6 of the display room 7, and communicates with the inside of the machine room 9. A similar pre-filter 31 is attached. The machine room 9
The inside is divided by the fan casing 27 into suction ports 29 and 32 and the main duct 8 side, and a duct heater 33 composed of an electric heater is arranged on the discharge side of the blower 26 which is the main duct 8 side.

At the four corners on the bottom surface of the frame of the bread baking system 1, moving wheels 36 are attached, so that the bread baking system 1 is movable.

Next, in FIG.
Is a general-purpose microcomputer which constitutes the control device C.
A dust sensor 42 for detecting the number of dust in the interior, an outside air temperature sensor 44 for detecting the outside air temperature, and a human sense for detecting the presence or absence of a person mainly by detecting a human body operation (FIG. 2) mainly in front of the showcase 5. The output of the sensor 46 is input.

The output of the microcomputer 41 is connected to the motor 26M of the blower 26 via an inverter circuit 47, and the output of the microcomputer 41 is connected to the duct heater 33 and the inside heater 23. . The motor 26M is connected to the inverter circuit 4
The number of rotations is adjusted by means of 7.

The operation of the above configuration will now be described. Assuming that frozen bread dough is stored in the freezer 10, the user first opens the door 20 of the freezer 10, takes out the frozen bread dough from the inside of the freezer 10, and then opens the oven 1.
The door 25 of No. 5 is opened and the dough is stored in the storage. Then, the process from thawing to baking of the dough is performed in the oven 15 by a preset process.

The bread thus baked is taken out of the oven 15, piled up on an appropriate tray, and stored and displayed on the shelves 16, 16 and the bottom surface 3C of the display room 7 of the showcase 5 in an exposed state. And the microcomputer 4
When the motor 26M is operated at a predetermined number of revolutions via the inverter circuit 47 by 1, the blower 26 sucks air from the lower front and discharges it to the upper rear.

By operating the blower 26, each suction port 2
Outside air is sucked from 9, 29, and 32 into the machine room 9 via the pre-filter 31. The suction from the suction ports 29, 29 can prevent dust soaring from the floor in front of the showcase 5 from heading toward the display room 7. Then, when passing through the pre-filter 31, relatively large dust in the air is captured by the pre-filter 31.
The outside air thus entered into the machine room 28 enters the HEPA filter 28 provided therein, where fine dust and bacteria are captured.

The air thus purified by passing through the pre-filter 31 and the HEPA filter 28 is
The air is blown up into the main duct 8 through the duct heater 33 by the blower 26. A part of the clean air rising inside the main duct 8 is taken into each shelf duct 17 by the guide members 18.

At this time, since the upper guide member 18 protrudes into the main duct 8 larger than the lower guide member 18, the amount of air entering each duct 17 in the shelf becomes substantially uniform. Also, the main duct 8
A part of the clean air rising inside is discharged into the display room 7 on each shelf 16 and the bottom surface 3C from the discharge ports 24 on the back surface 3A at a speed of about 0.1 m / s.

At this time, since the discharge port 24 is located above the space between each shelf 16 and the bottom surface 3C, the discharge port 24
・ The clean air discharged from is blown out above the freshly baked bread. As a result, the dust in the air above the bread is blown off to prevent the dust from adhering to the bread, and the drying is prevented from being promoted by blowing the air directly onto the bread.

Then, the remaining clean air flows in a forward direction along the main duct 8 and flows therethrough.
From 9 and 21, clean air is blown toward opening 6. Then, the blown clean air is finally supplied to the suction port 3
Since the air is sucked into the machine room 9 from the opening 2, an air curtain of clean air is formed in the opening 6. The air curtain prevents or suppresses dust from entering the display room 7 through the opening 6.

In this case, the air curtain is mounted on each shelf 16, 1
6 and the bottom surface 3C. In addition, due to the directivity of the outlets 12, 19, and 21 as described above, the outlet 1
The clean air blown out from 2 forms an air curtain outside the outlet 19, and the clean air blown out from the outlet 19 forms an air curtain outside the outlet 21. Accordingly, a triple air curtain is finally formed in the opening 6.

Based on the output of the dust sensor 42, the microcomputer 41 increases the rotation speed of the motor 26M by the inverter circuit 47 when the number of dust in the display room 7 is more than 100,000 per cubic foot (set value). Thus, the blowing amount of the blower 26 is increased. Thereby, the display room 7
Is supplied with a large amount of clean air from the outlets 12, 19, 21 and the outlets 24.

When the number of dust drops below the set value, the microcomputer 41 returns the rotation speed of the motor 26M to the initial value. Thereby, the microcomputer 4
1 controls the number of dust in the display room 7 to 100,000 or less per cubic foot.

Further, the microcomputer 41 increases the rotation speed of the motor 26M based on the output of the human sensor 46 even when a customer approaches the showcase 5. This prevents dust soaring by the action of the human body from entering the display room 7.

Further, based on the output of the outside air temperature sensor 44, the microcomputer 41 supplies electricity to the duct heater 33 to generate heat when the outside air temperature falls below a set value.
As a result, the clean air supplied to the display room 7 is heated and becomes warm air, so that the inconvenience of freshly baked bread and the like stored inside the cold season such as winter is prevented.

As described above, since the interior of the display room 7 of the showcase 5 has an environment of 100,000 or less dust per cubic foot, the dust is applied to the freshly baked bread stored in the display room 7 in an exposed state. Is prevented or suppressed, and it is possible to display and sell bread extremely hygienically.

Since the pre-filter 31 is provided on the suction side of the HEPA filter 28, clogging of the HEPA filter 28 due to relatively large dust can be prevented, and the replacement cycle of the HEPA filter 28 can be extended. Will be able to

The outlet 12 for blowing clean air,
Since 19 and 21 are respectively formed at the tip of each shelf 16 and the upper edge of the opening of the display room 7, an air curtain by clean air is formed in each of the openings 6 of the display room 7 partitioned by the shelf 16, and 6, the turbulence of the air curtain is reduced as compared with the case of blowing out only from the upper edge, and the effect of preventing dust from entering is improved.

Further, since the honeycomb material 13 is attached to each of the outlets 12, 19, and 21, the outlets 12, 19,
The clean air blown out from 21 is rectified by the honeycomb material 13, so that an air curtain with less disturbance can be configured. Further, the clean air flowing through the main duct 8 is smoothly introduced into the ducts 17, 17 by the guide members 18, and is blown out from the outlets 19, 21 at the front end.
A more stable and powerful air curtain can be constructed.

Further, since the upper corner portion of the outer case 2 is formed as a curved portion 2A, the clean air rising in the main duct 8 is smoothly turned forward and the decrease in the flow velocity is suppressed. Thereby, a stable and powerful air curtain can be constituted by the clean air blown out from the outlet 12 toward the opening 6 of the display room 7.

The upper air outlet forms an air curtain outside the lower air outlet, so that the air curtain formed by the clean air blown out from each of the air outlets 12, 19, and 21 flows downward. Disturbance due to collision with the shelves 16, 16 can be avoided. Also,
The outlets 12 and 19 are the outlets 1 of the shelves 16 and 16 immediately below.
Since the clean air is blown out toward the outside of 9 and 21, a triple air curtain is formed in the opening 6 of the display room 7 so that the air blown from the top becomes the outside sequentially. The curtain is more stable, and dust intrusion into the display room 7 is more effectively prevented or suppressed.

Further, the clean air rising in the main duct 8 is also supplied to the display room 7 from the discharge port 24, so that the display room 7
The air inside is also quickly cleaned. Here, the microcomputer 41 is also energized to the heater 23 inside the refrigerator, whereby an updraft is formed on each of the shelves 16, 16 and the bottom surface 3C. Due to the rising airflow, the dust can be prevented from dropping and adhering to food such as bread, and the pressure in the display room 7 is increased, so that the dust intrusion preventing effect is improved. In addition, a decrease in the temperature of the bread can be effectively suppressed by heating the inside heater 23.

The air that is blown out from each of the air outlets 12, 19, and 21 and forms an air curtain at the opening 6 is recovered from the air inlet 32, so that the cleanliness of the air is further improved, and the air quality is further improved. The curtain also stabilizes.
Further, since the wheels 36 for movement are provided on the bottom surface, the bread baking system 1 can be freely moved in the store,
It is possible to improve the sales / demonstration effect by the mobile sales format.

[0051]

Therefore, the bread dough can be taken out of the freezer, baked in an oven, and immediately displayed in the display room of the showcase.

This makes it possible to immediately display and sell freshly baked bread at a store or the like or to perform a sales promotion demonstration while the smell of bread during and immediately after baking drifts around. .

In particular, since the showcase is provided with an air purifying means to purify the air in the display room, dust enters from the outside and adheres to freshly baked bread displayed in the display room in an exposed state. Can be prevented or suppressed, and extremely hygienic display sales can be achieved.
