Description

  The present invention is a refrigerated garbage storage system that prevents odors from spreading in the vicinity of a community garbage collection place in an apartment house or a restaurant street, or a joint garbage collection place provided for several floors of a super high-rise apartment. It relates to a storage device.

  2. Description of the Related Art Conventionally, collective garbage collection places in apartment houses and restaurants have collected trash generating odors such as raw garbage, empty cans and empty bottles in thin synthetic resin garbage bags. Such garbage collection sites are usually open type where garbage bags are left exposed, so crows, mice, stray cats, etc. often come to break the garbage bags and damage the garbage in the bags. It can be seen. When a garbage bag is torn, not only garbage is scattered around, but bad odors generated from garbage etc. are diffused to the vicinity and cause trouble.

  In order to prevent the disadvantages of the above-mentioned open-type garbage collection site, for example, measures are taken to protect crows, rats, stray cats, etc. from breaking the garbage bags by covering them with a net. It cannot be said that it is. In particular, in apartment buildings, there is an increasing number of countermeasures by providing a closed type communal garbage collection site surrounded by concrete or blocks. However, in this case, although there is a convenience that garbage such as raw garbage can be taken out at any time, it causes a situation that garbage is always present in the garbage collection place, and a bad smell leaks out from the garbage collection place and adversely affects the vicinity. Can no longer be ignored. The communal garbage collection place set up in several floors in high-rise condominiums, etc. is closed, but if it is poorly managed, bad smell leaks out and depending on the wind direction, it may flow into neighboring units Has appeared. In this case, even if the garbage collection site is properly managed to solve the odor problem in the vicinity, bad odors remain inside the garbage collection site. Had the problem of suffering great inconvenience.

In order to solve such a problem, a technique has been developed in which the generation of bad odor is prevented by freezing garbage such as raw garbage stored in a garbage collection place. For example, in Patent Document 1, by covering the surface of garbage such as raw garbage with a frozen water film and keeping the frozen water film so that it does not thaw, the generation of bad odor is suppressed while suppressing the decay of the garbage, A dust deodorization storage method and apparatus that achieves complete deodorization measures are disclosed.
JP-A-5-18656

  According to the above-mentioned conventional frozen water film method, the garbage etc. is in an ice-packed state with freezing by the cooling means, and it can actively prevent the generation of bad odor, but it forms a frozen water film. In order to make an ice pack state, the temperature in the storage chamber must be set to about −10 ° C. and the freezing operation must be performed, and after the ice pack treatment, it is kept at about −2 ° C. so that the frozen water film does not thaw. You must continue driving. For this reason, there is a problem that the power consumption is increased and the cost is increased, and the temperature in the accommodation chamber is in the low temperature region as described above, and the surface of the garbage is in a frozen water film state. The work of taking out becomes troublesome, and the burden is increased for the trash taking out worker. In addition, even for those who have come to throw away the garbage, the burden of the waste throwing work increases because the storage room is in a frozen atmosphere.

  The present invention has been made to solve the above-described problems in the prior art, and can be operated with a small amount of power consumption, can suppress the generation of bad odors such as garbage, and can be used for garbage removal / trash disposal.

  Reference numerals 4 and 5 denote shutter-equipped ventilation means provided on the wall of the storage chamber 1, which are positioned on the opposing wall of the storage chamber 1, and these ventilation means 4 and 5 are both live in the storage chamber 1. The shutter is closed while dust 6 such as dust is stored, and the shutter is opened and ventilated only when the dust 6 is taken out from the storage chamber 1. As these ventilation means 4 and 5, it is preferable to use a pressure ventilation fan that can be surely exhausted without reverse rotation by an external wind pressure, but a general ventilation fan can also be used. In this case, the ventilation means 4 provided near the dust 6 and slightly below the middle part of the one wall 1a is a general ventilation fan, and the ventilation means 5 provided on the upper part of the other wall 1b. Is a pressure ventilation fan. Further, both the ventilation means 4 and 5 are simultaneously operated in conjunction with each other, and the shutters are also opened and closed simultaneously in conjunction with each other.

  As shown in FIG. 2, the interior of the storage chamber 1 is provided with a passage area 7 having a suitable width D at the center and linearly from the other wall 1b side to the one wall 1a side. 7 is connected to the opening / closing door 2 at the end on the wall 1b side. Thereby, when entering the storage chamber 1 from the open / close door 2, it is possible to walk along the passage area 7. Further, shelves 8 and 9 are respectively provided on the opposing walls 1c and 1d of the storage chamber 1 so as to project horizontally toward the passage region 7, and the upper and lower regions with the shelves 8 and 9 as boundaries are vertically 2 Stepped dust accumulation regions 10 and 11 are provided on both sides of the passage region 7. The indoor unit 3a of the cooling means 3 is located above the end of the passage area 7, the ventilation means 4 is located slightly below the center of the end of the passage area 7, and the ventilation means 5 is located in the passage area 7. It is located in the upper part of the starting end. The dust accumulation areas 10 and 11 are not limited to upper and lower two stages, and can be implemented, for example, with three or more stages or without providing the shelves 8 and 9, and a plurality of partition plates attached in the vertical direction. It may be configured to be partitioned by (not shown) and arranged side by side.

  Reference numeral 12 denotes an air cleaning means, which is mounted on the walls 1c and 1d of the storage chamber 1 so as to be positioned above the upper and lower two-stage dust accumulation regions 10 and 11 as shown in FIG. As the plurality of air cleaning means 12, for example, a deodorizer having a ventilation function can be used, and a porous and strong adsorbent such as activated carbon is preferably used. As a result, in each of the dust accumulation regions 10 and 11, malodors generated from the garbage 6 such as raw garbage can be adsorbed and removed.

  In FIG. 1, reference numeral 13 denotes odor detection means arranged at a proper position in the storage chamber 1, and the odor detection means 13 includes an odor detection sensor, which detects bad odor in the storage chamber 1 and outputs a detection signal thereof. The automatic control device 14 is configured to be input. The automatic control device 14 automatically controls the operation of the air cleaning means 12 and / or the ventilation means 4 and 5 based on the detection signal from the odor detection means 13. The automatic control device 14 is not limited to being attached to the outside of the storage chamber 1, and by attaching it to the inner surface of the upper wall in the storage chamber 1, necessary wiring can be arranged in the storage chamber 1. is there.

  In FIG. 2, reference numeral 15 denotes air blowing means, which are respectively attached to the upper end portions of the dust accumulation regions 10 and 11 on the side of the passage region 7, and form an air curtain on the side of the passage region 7 by blowing out air. The dust accumulation areas 10 and 11 are respectively shielded. As the air blowing means 15, for example, a powerful fan can be used, and the blower outlet is configured to have a wide width and approximately the length between the walls 1 a and 1 b of the storage chamber 1 along the passage region 7. In this case, it is possible to synthesize not only one fan but also a plurality of fans at regular intervals so as to synthesize an air curtain that shields the dust accumulation regions 10 and 11 respectively. is there.

  In the refrigerated storage apparatus according to the present invention configured as described above, the cooling means 3 is driven to supply cool air into the storage chamber 1, and the temperature in the storage chamber 1 is set to about 5 ° C. (3 ° C. to 7 ° C.). C.). If the inside of the storage chamber 1 is cooled to around 5 ° C., the odor generated from garbage etc. is almost completely prevented as compared with the conventional case where it is cooled below the freezing point (−10 ° C. to −2 ° C.) and ice packed. Although it is not possible, it is possible to suppress as much as possible the odor generated from garbage such as raw garbage. Thereby, the power consumption used by the cooling means 3 can be smaller than that of the conventional one.

  A user of this refrigerated storage apparatus opens the door 2 and enters the storage chamber 1, walks along the passage area 7, selects appropriate garbage accumulation areas 10 and 11, and disposes garbage 6 such as raw garbage. Although it is thrown away, the temperature in the storage chamber 1 is maintained at about 5 ° C. as described above, and since it is not a freezing atmosphere as in the prior art, no heavy burden is placed on the waste throwing work. Moreover, since each dust accumulation area | region 10 and 11 is shielded by the air curtain by the said air blowing means 15, even if bad odor has arisen inside the dust accumulation area | region 10, 11, it is not necessary to smell the bad odor directly. Further, since the inside of the dust accumulation areas 10 and 11 can be seen through the air curtain, the dust accumulation areas 10 and 11 to be discarded can be easily selected, and if the dust 6 is thrown toward the air curtain. , It can be easily thrown into the dust accumulation areas 10 and 11 without touching the air curtain. It is preferable that the trash 6 that generates odors is disposed in a predetermined thin synthetic resin trash bag in order to suppress bad odor as much as possible.

  As described above, the ventilation means 4 and 5 are accommodated because the shutter is closed while the garbage 6 such as garbage is accommodated in the accommodation chamber 1, and the open / close door 2 is closed during normal times. Even if a bad odor is accumulated in the chamber 1, it does not leak out of the storage chamber 1. Although not shown in the drawings, it is desirable to improve the sealing property of the door 2 with respect to the door frame by means such as interposing a sealing material so that bad smell does not leak from the gap between the doors 2. Thereby, the trouble around the vicinity of the storage chamber 1 is not caused by bad odor. Even when the accommodation room 1 is provided for every several floors of the super high-rise apartment, it is possible to prevent inconveniences such as bad smell intruding into dwelling units in the vicinity of the accommodation room 1 due to the wind direction or the like. Further, since the inside of the storage chamber 1 is not ventilated by closing the shutter during dust storage, it is possible to prevent the cool air in the storage chamber 1 from being dissipated. It can be kept in a refrigerated state around ℃.

  The degree (concentration) of bad odor in the storage chamber 1 during dust storage is detected by the odor detection sensor of the odor detection means 13. This detection signal is input to the automatic control device 14, and when the degree of bad odor exceeds a preset value stored in advance, an output signal is output from the automatic control device 14 to the air cleaning means 12 to clean the air. The means 12 is activated. As a result, the air cleaning means 12 sucks malodor in the storage chamber 1 and adsorbs it with the adsorbent, thereby reducing the degree of malodor in the storage chamber 1. Then, based on the detection signal from the odor detection means 13, the operation of the air cleaning means 12 is stopped by a stop signal from the automatic control device 14 when the degree of bad odor in the storage chamber 1 becomes the set value or less. . Accordingly, since the air cleaning means 12 operates only when necessary, the power consumption used by the air cleaning means 12 can be minimized. Further, unlike a general deodorizer, it does not always deodorize in a continuous state, so that the adsorbent lasts longer and the number of exchanges can be reduced, which is economical. Note that when the set value is set to a value close to the odorless state, a state in which there is almost no bad odor in the storage chamber 1 is obtained, so that the air blowout for shielding the dust accumulation regions 10 and 11 with an air curtain. It becomes possible to carry out without providing the means 15.

  Next, the situation at the time of taking out garbage from the storage chamber 1 will be described. When the trash is taken out, the open / close door 2 is normally opened, so that if a bad odor is accumulated in the storage chamber 1, it will be diffused to the outside. For this reason, it is desirable to remove the bad odor in the storage chamber 1 by operating the air purifying means 12 immediately before or during the dust removal operation. However, the air purifying means 12 does not have to be operated if the degree of malodor in the storage chamber 1 is equal to or less than the set value immediately before the dust removal operation. Thereby, it is possible to reduce the burden on the worker who takes out the dust by improving the working environment when taking out the dust.

  Further, during the dust removal operation, it is desirable to open the shutters of the ventilation means 4 and 5 to ventilate the interior of the storage chamber 1 in order to further improve the work environment during dust removal. In this case, on the basis of the detection signal from the odor detection means 13, an output signal is output from the automatic control device 14 to the ventilation means 4 and 5 when the value is below a set value. When the ventilation means 4 and 5 are actuated, the shutter is opened and the ventilation fan is rotated to exhaust the air in the storage chamber 1. In this way, when dust is taken out, the shutters of the ventilation means 4 and 5 are opened to ventilate. As described above, if the air cleaning means 12 is operated and deodorized immediately before or during the dust removal work, Ventilation can be performed without dissipating odors. Further, since both the ventilation means 4 and 5 are located facing the passage area 7, the exhaust in the storage chamber 1 can be efficiently performed. As described above, the ventilation means 5 is a pressure ventilation fan. It is possible to exhaust strongly and reliably without being influenced by external wind pressure.

  Further, during the dust discharge operation, the plurality of air blowing means 15 are stopped, and the shielding of the dust accumulation regions 10 and 11 by the air curtain is released. As a result, it is possible to easily carry out the operation of carrying out the dust 6 from each of the dust accumulation areas 10 and 11 and to reduce the amount of power consumption used by the air blowing means 15.

  The refrigeration storage apparatus in the above embodiment omits the description of the illumination means, but in order to illuminate the interior of the storage room 1 at night or the like, a lighting fixture such as a fluorescent lamp is attached to the upper wall or side wall of the storage room 1. It is preferable to install the switch in the vicinity of the open / close door 2 by installing it at a key point on the inner surface.

  The refrigerated storage apparatus according to the present invention can be suitably used as a shared trash collection place in an apartment house, a restaurant street, or the like, or a shared trash collection place provided every several floors in a super high-rise apartment.
