Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an apparatus that compresses and dehydrates food waste containing a large amount of water to reduce its size and facilitate disposal and other processing.

(b) Prior art This type of device is disclosed in Japanese Patent Publication No. 50-32136,
Disclosed in Japanese Patent No. 55-47654, food waste and the like are placed in a dewatering basket, and the dewatering basket is rotated at high speed by a motor to dehydrate the food waste. Therefore, a structure is required to incorporate the motor in a water-tight manner and a structure to collect food waste after dewatering, which inevitably complicates the structure and troublesome processing after dewatering. Therefore, as shown in Japanese Utility Model Publication No. 52-33105, it was considered to use a piston to press the garbage etc. against the cutter and dehydrate it while cutting, but in this case too, the garbage etc. after being cut and dehydrated. Since this method only continuously extrudes food waste, it is no different from the previous example in that it is troublesome to dispose of the extruded food waste and the food waste remaining in the device.

(C) Problems to be Solved by the Invention The present invention aims to simplify the structure and facilitate the post-processing of raw garbage, etc., and in particular, when the piston is driven by a vacuum device, the piston is smoothly moved. The aim is to maintain a certain level of movement.

(d) Means for solving the problem The solution according to the present invention is to provide a work chamber that communicates with a vacuum device with a lid for taking food waste in and out, and a storage chamber for storing food waste and the like through a garbage bag. A hollow airtight piston is provided in and out of the housing chamber, and the lid is hollow and communicates with the inside of the piston, and a vent hole to the atmosphere is provided on the side of the lid. The configuration is as follows.

(E) Action: Store garbage, etc. in the storage chamber through garbage bags, and remove the air from the work chamber using a vacuum device. Then, atmospheric pressure is applied to the inside of the piston from the ventilation hole on the side of the lid, and the piston extends and rushes into the storage chamber, compressing the food waste and the like inside the garbage bag. Even if water or the like splashes onto the lid, the piston communicates with the atmosphere on the side of the lid, so water will not get inside.

(F) Embodiment To explain based on the drawings, 1 is a working chamber arranged on a base 2, and a hollow lid 3 is provided in the upper opening of the working chamber so that it can be opened and closed freely and is made airtight with a gasket 4. An air vent pipe 5 is provided protruding from the side wall. 6 is a ventilation hole opened on the rear side of the lid 3; 7 is a household vacuum cleaner 8 removably connected to the air vent pipe 5;
9 is a hinge.

Reference numeral 10 denotes a storage chamber for garbage, etc. G, which is recessed in the inner bottom of the work chamber 1 so as to hang down into the base 2, and drain ports 11 are provided on the inner bottom surface. Reference numeral 12 denotes a liquid storage chamber arranged to airtightly cover the outer bottom of the storage chamber 10 via a filter 13, and a check valve 1 is connected to the lower part of the liquid storage chamber.
It communicates with a drain pipe 15 via 4. This check valve 14 closes when the degree of vacuum in the work chamber 1 increases, but remains open at normal atmospheric pressure.

Reference numeral 16 denotes a hollow piston fixed to the inner surface of the lid 3 so as to hang down, and the inside thereof is connected to the inside of the lid 3 and the ventilation hole 6.
It communicates with the atmosphere through the work chamber 1 and is airtight with the work chamber 1. This piston 16 is made of an elastic material (such as a bellows) that is vertically regulated by a core material 17.
The lower end pressing surface 18, which is normally contracted and made of a hard material, is opposed to the inside of the storage chamber 10 from above.

Thus, open the lid 3 and remove the filterable garbage bag 1.
9 is installed in a storage chamber 10, and garbage G, etc. is put therein. Then, close the lid and use the vacuum cleaner 8 as a vacuum device.
operate. The liquid water coming out of garbage etc. G initially flows down to the drain pipe 15 via the drain port 11, filter 13, liquid reservoir chamber 12, and check valve 14, but the degree of vacuum in the work chamber 1 increases. As the check valve 14 closes,
The liquid accumulates in the liquid storage chamber 12. On the other hand, the piston 16 expands as the degree of vacuum increases, pushes the pressing surface 18 into the storage chamber 10, and compresses the garbage G, etc. Liquid water generated by this compression also accumulates in the liquid reservoir chamber 12. At this time, the core material 17 prevents the piston 16 from expanding in the circumferential direction due to atmospheric pressure.

For example, the degree of vacuum P of the vacuum cleaner 8 is about 0.2 kg/cm ² , the diameter D of the circular pressing surface 18 is 200 mm, and the efficiency K
When 80%, the compressive force F is F=K・πD ² /4・P=0.8×π・20 ² /4×0.2≒50K
It is g. That is, even if the household vacuum cleaner 8 is used, sufficient force to compress G such as garbage can be easily obtained. Note that, like a central cleaner, if air intake ports are prepared in advance at various locations within the house, the ease of use will be doubled.

When the vacuum cleaner stops operating after a predetermined (arbitrary) compression time has elapsed, the air pressure in the work chamber 1 rises due to air leakage on the vacuum cleaner 8 side, and the piston 1 automatically closes.
6 returns to the upward position, and the check valve 14 returns to the open position. Therefore, the liquid water in the liquid storage chamber 12 flows down and is discharged, and the dehydrated and compressed garbage G remains solidified in the bag 19 in the storage chamber 10. Therefore,
Open the lid 3, take out the bag and dispose of it as appropriate. bag 19
If there is still room left, the next garbage G is placed in the bag 19 in the storage chamber 10, and the above-mentioned operation is repeated.

In this way, in this embodiment, the ventilation hole 6 is opened on the rear side surface of the lid 3, and the inside of the piston 16 is communicated with the atmosphere from there, so that even if water or the like splashes on the top surface of the lid,
They hardly ever enter the piston 16, and the piston 16 can be smoothly extended and retracted.

Next, we will discuss other embodiments (A), (B), (C), and (D) that can be implemented even if the ventilation hole 6 is opened on the top surface of the lid 3.
I will explain about it.

(A) As shown in Figure 2 A, there are two protrusions on the pressing surface 18.
0..., the shape of which is shown in Figure 2 B, C, and D, consists of multiple rows of long rectangular columns, small-diameter cylinders,
Let it be a rectangular prism with a short length. As a result, the action of cutting the garbage, etc. G is generated, the gap between the garbage, etc. G is reduced, and the compression ratio is increased.

(B) As shown in FIG. 3, the outer circumferential shape of the storage chamber 10 is made into a horizontally elongated shape such as an oval or an inertial circle, and the outer circumferential shape of the pressing surface 18 of the piston 16 is also shaped like the outer circumferential shape of the storage chamber 10. Do the same as. As a result, elongated garbage such as fish, etc.
can be put into the storage chamber 10 as is without having to be folded in half in advance, and the work can be proceeded without pretreatment.

(C) As shown in FIG. 4, the check valve 14 includes a valve seat 22 and a lightweight valve body 23 disposed within an airtightly sealed valve box 21. 24 and 25 are liquid storage chambers 12
and a communication port to the drain pipe 15, and 26 is a mounting stand for the valve body 23. That is, normally the valve body 23 is placed on the mounting table 2.
6, open the valve seat 22, and open both communication ports 2.
4 and 25 are communicated with each other, but when the degree of vacuum in the work chamber 1 increases, the valve body 23 is sucked up and the valve seat 22
is in contact with and held (see the dashed line in the figure),
The communication ports 24 and 25 are closed. Then, when the operation of the vacuum device 8 is stopped, the valve body 23 falls onto the mounting table 26, and the valve seat 22 is opened again (see the solid line in the figure).

(D) As shown in Figure 5 A, B, and C, the piston 1
A coil spring 2 for returning (raising) the piston 16 is installed between the pressure receiving surface 27 in the lid 3 and the lower surface of the lid 3.
Place 8. In this case, the lid 3 is of a type in which the upper surface 29 and the lower surface 30 are connected with a spaced interval using screws or the like, and the coil spring 28 is formed into a unit with the cylindrical cover 31 in advance. This cover 31
A through hole 32 is bored, and a flange 33 is attached to the upper end of the hole 32.
We would like to provide a pin 34 and suspend the pin 34 from the upper part of the inside. When unitizing, first, the lower end of the coil spring 28 is hooked to the hook 35 provided with the base plate, and the spring 28 is placed inside the cover 31. Then, the upper end of the spring 28 is pulled up using a tool from the upper end opening of the cover 31, and this upper end is hooked to the pin 34.

The cover 31 and coil spring 28 that have been made into a unit in this way are attached to the upper and lower surfaces 29, 3
0, first attach the flange 33 to the bottom surface 3.
The pressing surface 18 is screwed onto the upper part of the hook 35 and hangs down, and the substrate of the hook 35 is pressed against the pressure receiving surface 27.
It is screwed in from the side. Cover 31 like this
The lower end of the piston 16 is in pressure contact with the pressure receiving surface 27 via the substrate, and the piston 16 is stopped on the lid lower surface 30 by this pressure contact force. After this, cover upper and lower surfaces 29, 30
It combines.

When the vacuum device 8 is activated, the pressure receiving surface 27 receives atmospheric pressure through the ventilation hole 6, the inside of the lid 3, the cover 31, and the through hole 32, causing the piston 16 and the coil spring 28 to extend downward, and the pressure receiving surface 27 to be compressed by the pressing surface 18. Then perform the compression work (see Figure 5 C). When the operation of the vacuum device 8 is stopped, the piston 16 contracts due to the spring 28 and its own contraction force, and rises until the pressure receiving surface 27 comes into pressure contact with the lower end of the cover 31, causing the pressing surface 18 to escape from the storage chamber 10. (See Figure 5 A and B).

(G) Effects of the Invention According to the present invention, food waste can be dehydrated with a simple structure, compressed to make it smaller, and post-processing such as disposal can be easily performed. Can maintain smooth movement.
