Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended for the temporary storage and disposal of packaging waste such as food waste in hospitals, food waste, leftover food, cooking waste and other wastes that generate odors during storage. The present invention relates to a refrigeration type waste treatment device used.

[0002]

[Prior Art] Paper diapers used in hospitals, nursing homes, etc., and temporary storage of food waste, leftover food, cooking waste etc. from restaurants, supermarkets, etc. should be put in a plastic bag etc. and collected in a special room or box. Is.

[0003]

However, each time a room is opened or a bag is opened, a bad odor is generated and it is unsanitary, but there is nothing to do and only the worker is forced to suffer. The present invention is in the refrigerated state during the input and storage of these filth,
It was developed for the purpose of providing a box type that can be sealed and miniaturized at the time of packaging and dumping and can be placed in one corner of the room. In order to solve this problem, the present inventor previously developed a refrigerating / heating type waste treatment device in Japanese Patent Application No. 3-12043. However, since it requires repeated cooling and heating, some problems remain in terms of safety and high cost.

[0004]

[Means for Solving the Problems] As a means for solving the problem, a heat insulating chamber 2 having an insulating cover 1 on its upper surface, a cooling compressor 3 below the heat insulating chamber 2, a vacuum pump 4, and a device for supplying cold air to the heat insulating chamber 2 (cooler). ) 6, a refrigerating type sewage treatment apparatus having a structure in which a breathable basket 7 for accommodating a resin film bag is provided in the refrigerating type heat insulating chamber has been developed.

[0005]

With such a structure, the cold air from the cold air supply device 6 of the cold storage type puts the filth in a refrigerated state during storage.
As a result, the bad odor is suppressed, and the air inside the resin film bag is sucked and removed by the vacuum pump at the time of packaging and dumping, and the contents are sealed and miniaturized to facilitate dumping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of the apparatus of the present invention taken along the line AA in FIG. 2, and FIG. 2 is a sectional view taken along the line BB in FIG. Figure 3
Is a front view. FIG. 4 shows an example of a circuit diagram. As seen in these figures, in this device, a heat insulating lid 1 is hingedly attached to the upper surface of an elongated body casing 10. Front upper body casing of body casing 10
The heat insulating chamber 2 in 10 has a heat insulating structure made of a heat insulating material. A cooling compressor 3 is provided below the heat insulation chamber 2, and the heat insulation chamber 2 and the cooling compressor 3 are partitioned by a heat insulation floor 5, and a cold air supply device 6 connected to the compressor is provided in the heat insulation chamber 2. A vacuum pump 4 is located next to the compressor, and its suction port guided by a pipe opens into the heat insulating chamber 2. In such a refrigerating type heat insulation chamber, a porous air-permeable basket 7 for accommodating the resin film bag is provided, and waste such as dirty paper diapers after use can be thrown into the resin film bag. In this case, a normal polyethylene film was used.

[0007] The electric circuit mainly includes an operation control related circuit of the compressor for cooling and the vacuum pump P. An internal fan motor FM and a protective thermostat T are provided in front of the circuit for the compressor unit to prevent an accident in the refrigerant pipe because the compressor cannot rotate unless the temperature is lower than a predetermined temperature. Also, the vacuum pump is a timer type. When the main switch S ₁ is turned on, the internal fan motor FM rotates, and when the temperature is equal to or higher than the predetermined temperature, the thermostat T is in the ON state, and the cooling operation is controlled to a low temperature. In this state, the gate input switch S ₂ is turned on and the timer TM can be set. When the timer is set, the vacuum pump rotates for the set time to reduce the pressure in the refrigerator. At the time of packaging and discarding, the vacuum pump sucks and removes the air inside the resin film bag, and the contents are sealed and miniaturized to enable the dumping. When the timer is turned off, the decompression is naturally released, and the waste stored in the resin film bag can be taken out in a small capacity.

Table 1 shows the specifications of the refrigerating type waste treatment device in this embodiment. Table 1 External dimensions Width 650 Depth 650 Height 930 Inner diameter Width 560 Depth 560 Height 570 Storage capacity 20 diapers 20 urine absorbing pads 40 doors Top hinge hinged 1-door compressor Single phase 100 150W Cooler fin tube type forced Circulation type 2W × 1 Condenser Wire and tube type Forced air cooling type 4W Internal temperature Cooling 0-5 ℃

The method of using the device of the present invention will now be described. First, the film bag is set inside the basket 7 in the refrigerator. Put in used diapers. Cold storage. When it is filled with diapers, etc., close the mouth of the film bag to the suction port of the vacuum pump with a rubber band to prevent air from leaking and close it. The switch S of the vacuum pump is turned on to suck the air inside the film bag. When the bag is vacuum-packed after a predetermined suction time has passed by a timer, the bag mouth is closed with an adhesive tape or the like to remove the suction mouth, and each bag is taken out and discarded.

[0010]

EFFECTS OF THE INVENTION Since the refrigeration type waste treatment device of the present invention has the above-mentioned configuration, it is possible to store used diapers and household waste in a small capacity until the next collection day. Since diapers are stored at a low temperature (about 4 ° C), there is no odor even when the lid is opened. By sucking the air in the bag and packaging it in a vacuum before discarding it, the capacity of the diaper is reduced to about half. It is a compact device that does not have limited installation locations and does not generate noise. Since it is only refrigerated, it is safe, and since no complicated mechanism is provided, the manufacturing cost is low, contributing to cost reduction.
