JPH07315501A - Mechanism for preventing foul smell emitted from refuse container and peripheral device therefor - Google Patents

Abstract

PURPOSE:To prevent a foul smell from being emitted, when refuse having a smell is to be stored, by providing both an air discharge port for making the pressure of a refuse storing part negative, which is either manufactured as an integrated body with or attached to a container for storing the refuse and having comparatively high airtightness and a device for opening/closing the air discharge port. CONSTITUTION:By means of an air discharge port 5, which makes the pressure of a refuse storing part 7 negative as an integrated body with a refuse container 3, and a device for opening/closing the air discharge port 5, the gas in the storing part 7 is extracted from the outside, thereby making the pressure of the storing part 7 lower than that of the outside air. As a result, by transporting the refuse with the air discharge port 5 closed, the refuse can be transported, as the pressure of the refuse storing part 7 is kept lower than that of the outside air. If the pressure of the refuse storing part 7 is equal that of the outside air, a foul smell is emitted to the outside unless the degree of the airtightness of the refuse storing part 7 is raised. However, if the pressure of the refuse storing part 7 is negative, the airtightness is raised, owing to the higher pressure of the outside air. In addition, since an air flow flows into the refuse storing part 7 even if there is a slight leakage in the refuse storing part 7, the foul smell will never be emitted to the outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for storing wastes such as dust that emits an offensive odor and its peripheral apparatus.

[0002]

2. Description of the Related Art In recent years, the amount of garbage generated at homes and offices has been increasing, and the increase in garbage generating an unpleasant odor has attracted great attention as a factor that hinders people's comfortable lives. There is. According to one statistic, the amount of raw garbage generated from an average household of four people exceeds 1 kg per day, and these garbage are usually collected at regular intervals. It is necessary to store each household until the day, and in many cases, it is stored in a plastic bag that can be taken out as it is on the day of collection. However, especially in summer, kitchen garbage begins to emit a peculiar offensive odor even after being stored for about a day, and therefore often the peculiar odor leaks out into the interior of a plastic bag. Therefore, there are many cases in which life has been devised such as taking the garbage packed in plastic bags to the balcony.
In addition, since the plastic bags for trash on the market have a larger storage capacity than the amount of trash generated at one time, usually the bag containing the trash is reopened and the newly generated trash is put into that bag. The action of throwing in and closing again will be repeated several times, but at that time, the unpleasant odor of the dust thrown in before will leak out to the surroundings, and you have to feel uncomfortable every time you throw in the dust. It will not happen.

As a countermeasure against these problems, a masking method of spraying a fragrance to the dust is generally used. However, the fragrance has a poor sustainability, and the odor generated by the dust and the odor of the fragrance are mixed to make it unique. It is impossible to completely mask an unpleasant odor, such as a nasty odor, and the current situation is that it does not completely prevent odors. In addition, recently, a processing device focusing on the treatment of raw garbage has been devised and sold, but as shown in the examples of paper diapers and shells, none of them is intended to treat all the garbage in principle, With these devices, garbage and wastes that emit an unpleasant odor that cannot be processed remain, and the current situation is that they are not effective as a complete countermeasure.

[0004] In addition, restaurants are often installed on the upper floors of buildings, etc., with the view as a selling point, but problems have been pointed out regarding the processing of wastes that generate an unpleasant odor. ing. That is, in relatively low-rise buildings, the method is to carry the garbage from the upper floors through the garbage shooter to the garbage collection place installed on the ground, but with this method, the bag containing the garbage is impacted by the fall. There is a drawback that the dust that breaks and emits an offensive odor at the accumulation place of dust is scattered as it is and emits the offensive odor in the surrounding area. Also, in high-rise buildings and low-rise buildings that do not use a garbage shooter, a method is used to transport the garbage that emits an offensive odor from the upper floors to the ground using an elevator.
There is a drawback that the construction cost rises as a result of having to take measures such as installing an elevator exclusively for garbage because the offensive odor generated by garbage leaks and fills the inside of the elevator.

[0005]

DISCLOSURE OF THE INVENTION The present invention prevents the emission of offensive odors during the storage of the above-mentioned waste, ensures a comfortable living environment in each home or office, and transports the waste from the upper floors of buildings and the like. In this case, by not leaking offensive odors, it is possible to carry garbage that emits offensive odors in an ordinary elevator for transporting personnel, and there is no need to install a special transportation device such as an elevator dedicated to garbage, resulting in a cost reduction for building construction. The purpose is to reduce the amount of waste and to make the environment around the waste treatment site comfortable.

[0006]

In order to solve the above-mentioned problems, as described in claim 1, the present invention is integrated with or attached to a casing for storing relatively airtight refuse, An exhaust port for making the waste storage unit under negative pressure and a device for opening / closing the exhaust port were provided.

Further, as described in claim 2, the waste stocker of claim 1 is provided with a deodorizing function in the exhaust path.

Further, as described in claim 3, claim 1
It was decided to provide a deodorizing function in the exhaust path of the exhaust system used in combination with the garbage stocker.

Further, as described in claim 4, a device for making the dust storage unit negative pressure and a device for integrally building the dust storage unit or attached to the casing to put the dust storage unit at a negative pressure. In order to achieve this, a mechanism for discharging the gas in the waste storage unit to the outside was provided, and a function to deodorize the gas discharged from the waste storage unit to the outside was provided.

Further, as described in claim 5, the control of the device for setting the negative pressure in the storage section is performed by detecting the negative pressure in the waste storage section.

[0011]

[Operation] For example, before transporting the waste by providing an exhaust port for making the waste storage unit negative pressure and a device for opening and closing the exhaust port integrally with or attached to the case for storing the waste. Using this exhaust port and a device for opening and closing the exhaust port, the gas in the waste storage unit is evacuated from the outside to make the pressure inside the waste storage unit lower than the outside air, and keep the exhaust port closed when transporting the waste. By carrying the waste, the waste storage unit can carry the waste while maintaining a lower pressure than the outside air. Here, if the waste storage is at the same pressure as the outside air pressure, unless the airtightness of the waste storage is increased considerably, the offensive odor emitted from the inside of the waste storage leaks to the outside, but the waste storage is under negative pressure. With this, if the storage portion has a certain degree of airtightness, the airtightness can be further improved by the pressure of the outside air. Even if there is a slight leak in the waste storage unit, the airflow only flows into the waste storage unit from the outside, so the offensive odor generated from the waste storage unit does not leak to the outside.

Further, by providing a deodorizing function in the exhaust path of the waste stocker described in claim 1, when the gas in the waste storage section is sucked and exhausted from the exhaust port, the offensive odor generated by the dust is generated around the work area. Without releasing
It is possible to maintain a comfortable environment around the garbage disposal work area.

Alternatively, by providing a function of deodorizing the exhaust path of the exhaust device used in combination with the waste stocker described in claim 1, the waste stocker of the waste stocker sucks the gas in the waste storage section from the exhaust port. When exhausting gas, the offensive odor of dust is not emitted to the surroundings of the work area, and a comfortable environment around the waste processing work area can be maintained. Further, when a large number of the dust stockers are used, it is economical because a plurality of dust stockers can be deodorized by one exhaust device.

A device for making the waste storage unit negative pressure and a device for making the waste storage unit negative pressure integrally with or attached to the case for storing the waste storage unit. A device equipped with a mechanism for discharging the above gas to the outside and a function for deodorizing the gas discharged from the waste storage to the outside must use an exhaust device outside because it is independent of itself. Since the waste storage section can be kept at a negative pressure without being used and the exhaust gas is deodorized by the deodorization section, not only the waste storage section but also the exhaust section for making the waste storage section a negative pressure emits an offensive odor to the outside. There is no such thing. Furthermore, even if odorous waste is already stored in the waste storage unit, when the waste is taken in and out, if the gas in the waste storage unit is discharged to the outside from the discharge mechanism, the air flow will be stored from the outside. Since it is discharged after deodorizing through the parts, the offensive odor of dust does not spread to the surrounding area.

In addition, a device for making a negative pressure in the waste storage unit and a device for making a negative pressure in the waste storage unit integrally with or attached to the housing for storing the waste, The negative pressure of the waste storage unit is detected by detecting the negative pressure of the waste storage unit in a device that is equipped with a mechanism to discharge the gas of the waste unit to the outside and has a function to deodorize the gas discharged from the waste storage unit to the outside. By controlling the above, it is possible to reliably keep the waste storage unit at a negative pressure, and it is possible to reliably prevent the offensive odor from spreading from the waste storage unit to the surroundings.

[0016]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1A is a sectional view of an example of the dust stocker according to claim 1. A tubular exhaust port 5 is provided on a side surface near the bottom surface of the housing 3 that can withstand a specified external pressure, and a valve 6 is attached to the exhaust port 5.
Further, a lid packing 4 made of silicon rubber, which is a corrosion-resistant material, is attached to the upper part of the housing 3, and the lid 2 capable of withstanding a specified external pressure is arranged through the lid packing 4. Has been done. When using this container for transporting odorous waste, put the trash stocker on a portable device such as a trolley, and put the odorous waste put in a plastic bag for garbage into a plastic bag etc. Put it in the egg storage unit 7,
Then, the user holds 1 and covers the lid 2 from the upper part of the housing 3, and the separately installed exhaust device and the exhaust port 5 are connected. Then, a separately installed exhaust device is driven to gradually open the valve 6 to guide the odorous gas in the waste storage unit 7 to the outside. By the above operation, the waste storage unit 7 has a negative pressure as compared with the outside, and the housing 3 and the lid 2 are exposed to the external pressure, and the packing 4 for the lid is crushed, so that the airtightness is increased even in the case where the airtightness is not sufficient. be able to. When the waste storage unit 7 reaches the specified pressure, the worker operates the valve 6
Then, the exhaust port 5 and the separate exhaust device are cut off, and they are transported to a predetermined position by a portable device such as a truck.
Even if there is a slight gap in the waste storage unit 7 of the waste stocker, the internal pressure during transportation is lower than that of the outside, and the airflow only flows in the direction into the waste storage unit 7 through the gap, so The offensive odor inside the storage unit 7 does not leak to the outside. When the transportation is completed and the vehicle arrives at the destination, the operator gradually opens the valve 6 to introduce the outside air into the waste storage unit 7, and after the pressure in the waste storage unit 7 and the external pressure are balanced. Take the lid 1 and open the lid 2, and take out the odorous waste stored in the waste storage unit 7 together with a plastic bag or the like. It should be noted that the waste stocker that has finished transportation is preferably transported to a predetermined position again if the odorous waste is not put into the waste storage unit 7 by making the waste storage unit 7 negative pressure again by the same procedure if possible. It is not necessary to use the trash stocker only for transporting odorous trash, remove the lid 2 and attach a plastic bag for trash so that trash can easily enter, and use it as a trash box as it is. Alternatively, the functions of the exhaust port 5 and the valve 6 may be used. Further, in that case, a device for fixing a plastic bag for dust or the like is provided at an appropriate position above the outer peripheral portion of the housing 3, and the mouth portion of the plastic bag for dust is fixed here to fix the packing 4 for the lid or Further, it is desirable to cover a part of the housing 3 to prevent foreign matter from adhering to the portion that comes into contact with the lid 2 and reduce the airtightness. Alternatively, the lid packing 4 may be arranged on the lid 2 side in the sense of preventing damage to the lid packing 4.

FIG. 1B is an example in which a deodorizing function is added to the exhaust path of the waste stocker according to claim 2,
Activated carbon cassette 8 inside the waste storage 7 immediately before the exhaust port
This is the case when is arranged. As is well known, activated carbon has a function of efficiently adsorbing and removing malodorous gases such as ammonia and methyl mercaptan. By arranging this in the exhaust path of the above-mentioned waste stocker, the activated carbon of the waste storage unit 7 When the odorous gas is discharged to the outside, the odorous gas always passes through here, and thus the discharged offensive odor is deodorized, and it is possible to prevent the offensive odor of dust from spreading to the surroundings. In the present embodiment, the activated carbon was made into a honeycomb shape for the purpose of reducing the pressure loss of the passing gas, and the activated carbon had to be exchanged at the time of saturated adsorption of the malodorous gas, so that it was mounted in a cassette shape. However, the deodorizing function to be used does not necessarily have to be activated carbon, and any catalyst having the same or higher effect as a catalyst may be used. Further, the position where the deodorizing function is arranged does not have to be inside the dust storage unit 7, and may be arranged, for example, in the exhaust port 5 so as to be replaceable as a cylindrical cassette.

FIG. 2 is a block diagram of a waste stocker and an exhaust device according to claim 3. As shown in FIG. 2, the exhaust device 10 is connected to a waste storage unit 7, a valve 6, and a waste stocker 9 having an exhaust port 5 through a pipe 13,
The garbage stocker 9 and the exhaust device 10 are used in combination. When the odorous gas in the waste storage unit 7 is discharged to the outside, the odorous gas passes through the valve 6, the exhaust port 5 and the intake mechanism 11 such as a pump of the exhaust device 10 and the deodorizing mechanism 12 such as activated carbon. The discharged gas is deodorized, and it is possible to prevent the offensive odor of dust from spreading to the surroundings. Here, the deodorizing mechanism 12 may be located at any position of the exhaust device 10, and may be on the upstream side of the intake mechanism 11. As the deodorizing mechanism 12, for example, a method of combining ozone and a catalyst can be used.

FIG. 3 (a) is an example of a dust stocker according to a fourth aspect of the present invention, and is a perspective view of a part of which is broken, and FIG. 3 (b) is a broken part of FIG. 3 (a). It is a perspective view which expanded and drew a corner part without fracture. In this example, the space surrounded by the housing 3 and the lid 2 that can withstand the specified external pressure is used as the waste storage unit 7, and the intake space spacer 17, the deodorizing mechanism 12, and the fan 14 are connected in series on the bottom surface of the waste storage unit 7. It is arranged. Here, since the gas that passes through the fan 14 and is discharged from the exhaust port 5 provided in the housing 3 to the outside of the housing 3 always passes through the deodorizing mechanism 12, the waste storage unit 7 Than. The discharged gas is always deodorized, and no strange odor is discharged. A control box 15 accommodating an electric circuit for controlling the waste stocker is arranged beside them. Here, as shown in FIG. 3B, an opening / closing door 18 made of iron integrated with the housing 3 by a hinge 21 is provided at a position where the fan 14 of the housing 3 is close to the fan 14. A packing 19 for an opening / closing door and an electromagnet 20 are arranged in a portion where the four circumferences are in contact with the housing 3. Further, a packing for ensuring the airtightness of this portion is arranged between the lid 2 and the housing 3. When using the waste stocker, the cord 16 is connected to the power line. As a result, power is supplied to the control box 15, and control is started by the built-in control circuit. When power is first input to the waste stocker, the switch 22 starts the same sequence operation as when the waste stocker is instructed to store, and the fan 14 is activated to exhaust the gas in the waste storage unit 7 to the outside. Then, the electromagnet 20 becomes excited, and the door 18 is attracted by the electromagnet due to the magnetic force and adheres to the packing 19 for the door to seal this portion. After that, the fan 14 is stopped by the sequence instruction of the control circuit, but in this state, the upper portion of the dust stocker is kept airtight by the lid 2 and the housing 3 and the packing located between them, and the periphery of the opening / closing door 18 is also kept. Since the airtightness of the part is still maintained by the open / close door 18 and the packing 19 for the open / close door, the waste stocker 7 itself of the waste stocker keeps the airtightness, and the fan 14 allows the internal gas of the waste stocker 7 to be kept. As a result, the waste storage unit 7 has a negative pressure compared to the outside. The sequence for setting the negative pressure to the waste storage unit 7 at the time of power-on is not always necessary, but for example, in the case of power failure, it is for recovering the odor leakage prevention mechanism from the waste storage unit 7 at the same time when power supply is resumed. Is. From this state, when the user actually stores the odorous waste, the user issues a throwing-in instruction for throwing in the dust through the switch 22, and when the built-in control circuit receives the signal, the fan 14 is activated, and the Immediately after that, the electromagnet 20 loses its magnetic force by cutting off the applied voltage, and the open / close door 18 is opened, the airtightness of the waste storage 7 is lost, and the internal pressure of the waste storage 7 becomes substantially equal to the external pressure. Then, the user can easily remove the lid 2. In this state, the user disposes the waste plastic bag or the like in the waste storage unit 7 and loads the waste or the like, or loads the waste plastic bag or the like into the waste storage unit 7. Considering here that odorous waste has already been stored in the waste storage unit 7, the fan 14 is operated when the loading instruction is given.
, The gas flow flows into the waste storage unit 7 and is discharged to the outside through the deodorization mechanism 12. Therefore, the offensive odor generated by the odorous waste stored in the waste storage unit 7 leaks to the surroundings. There is no. When the user finishes the operation of throwing in the dust, he / she attaches the lid 2 and instructs the waste stocker to store the waste through the switch 22, and the waste stocker stores the waste without leaking an offensive odor according to the sequence of the waste storage state described above. It can be carried out. Here, although the waste stocker maintains airtightness during storage, it costs a lot of money to create a strict airtight state and maintain the negative pressure in the waste storage unit 7 for a long time. In this case, the control circuit is provided with a timer function to maintain the negative pressure of the waste storage unit 7 by performing the same operation as when the storage state is instructed through the switch 22 at regular intervals. In this example, the deodorizing mechanism 12 and the fan 14 are arranged in the waste storage unit 7. However, this is not always necessary. For example, a ventilation hole is provided on the bottom surface of the waste storage unit 7 and the housing attached to the bottom surface is used. You may store these parts. Further, instead of using the fan 14 as the exhaust device, for example, a pump or the like may be used. In addition, in order to improve the airtightness of the waste storage unit, the waste storage unit 7 and the housing 3 may have a double structure. Also,
The opening / closing control of the exhaust port 5 may use a mechanical mechanism or a valve.

FIG. 4 is a block diagram of a control system for controlling the negative pressure of the waste storage unit 7 of the waste stocker according to claim 5 by detecting the negative pressure of the waste storage unit 7. For example, a signal indicating the pressure output from the pressure detection unit 23 using a semiconductor pressure sensor or the like and a preset reference signal output from the reference signal generation unit 24 are compared by a comparator 25 such as a comparator element. The comparison signal is I
If the pressure detected by the pressure detection unit 23 is higher than a set value, the operation necessary for maintaining the pressure of the dust storage unit 7 is sent to the main control circuit 27 constituted by C and the like, and the exhaust port control mechanism 28 is operated. This is performed using the exhaust device 29. The operation unit 26 is a user's manual switch, and by this operation, the instructed operation can be performed regardless of the pressure state of the waste storage unit 7. According to this method, it is not necessary to maintain the negative pressure state of the waste storage unit 7 due to, for example, a time sequence, unnecessary power consumption is eliminated, and the airtightness of the waste storage unit 7 is lowered for some reason. Even in such a case, the offensive odor does not leak from the waste storage unit 7.
