Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a device 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 This invention simplifies the structure by omitting the rotary drive unit, facilitates post-processing of food waste, and further reduces the compressive force of the piston against food waste. The purpose is to improve the structure and downsize the compression means.

(d) Means for solving the problem The solution according to the present invention consists of a storage chamber in which garbage, etc. is stored through a garbage bag, in a work chamber that communicates with a vacuum device, and a storage chamber that communicates with the atmosphere and communicates with the work chamber. The piston is provided with an airtight hollow piston, and the piston has a pressure receiving surface and a pressing surface which is smaller in area than the pressure receiving surface and which can freely move in and out of the accommodation chamber.

(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, the piston expands in response to atmospheric pressure on its pressure-receiving surface, pushes its small-area pressing surface into the storage chamber, and uses an extremely strong force to compress food waste and the like inside the garbage bag and dehydrate it. Therefore,
After the compression force is released, the garbage, etc., with its water content significantly reduced, is taken out of the garbage bag and disposed of.

(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. Reference numeral 6 designates a ventilation hole opened in the center of the upper surface of the lid 3, reference numeral 7 designates an intake hose of a domestic vacuum cleaner 8 which is removably connected to the air vent pipe 5, and reference numeral 9 a hinge.

Reference numeral 10 denotes a storage chamber for garbage G, which is formed by standing a cylindrical wall 11 at the inner bottom of the work chamber 1, and has small-diameter drain ports 12 on the inner bottom. Reference numeral 13 denotes a liquid reservoir chamber disposed to cover the liquid drain ports 12 from the outer bottom, and the lower part thereof communicates with a liquid drain pipe 15 via a check valve 14. This check valve 14 closes when the degree of vacuum in the work chamber 1 increases, but remains open at normal atmospheric pressure.

16 is a hollow piston fixed to the inner surface of the lid 3 so as to hang down, and a bellows 1 fixed to the lower surface of the lid 3.
7, and a pressure receiving surface 1 made of a plate material with a large diameter d ₁ at the bottom of the bellows.
8 and a pressing surface 19 vertically disposed from the center of the pressure receiving surface 18 so as to have a diameter d ₂ smaller than that of the pressure receiving surface 18 . The inside of this piston 16 is communicated with the atmosphere through the lid 3 and the ventilation hole 6, and is airtight with the working chamber 1. In this way, the piston 16
The pressing surface 19 faces the housing chamber 10 from above, and is moved into and out of the housing chamber 10 by expansion and contraction of the bellows 17. 20 is the core material of the bellows.

Thus, open the lid 3 and remove the filterable garbage bag 2.
1 is installed in the storage chamber 10, and garbage etc. G 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 G initially flows down to the drain pipe 15 via the drain port 12, the liquid storage chamber 13, and the check valve 14, but when the degree of vacuum in the work chamber 1 increases, the liquid water flows in the opposite direction. Since the stop valve 14 is closed, the liquid accumulates in the reservoir chamber 13. On the other hand, the pressure receiving surface 18 of the piston 16 receives atmospheric pressure, and as the degree of vacuum increases, the bellows 17 expands, and the pressing surface 19 rushes into the storage chamber 10 to compress G such as garbage. The liquid water generated by this compression is also stored in the liquid storage chamber 12. At this time, the core material 17 is the piston 16
This prevents the gas from expanding in the circumferential direction due to atmospheric pressure.

Here, the surface pressure _P2 generated on the pressing surface 19 is: P2=(π/4d1) ² /(π/4d2) ² ×P1=(d1/d2) ²
×P1 (Kg/cm ² ) However, P ₁ is the degree of vacuum in the working chamber 1. In other words, even if the degree of vacuum of the vacuum cleaner 8 is about 0.2Kg/ ^cm2 ,
The compression pressure on the pressing surface 19 can be ensured to be sufficient to compress G such as garbage. 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 13 flows down and is discharged, and the dehydrated and compressed garbage G remains solidified in the bag 21 in the storage chamber 10. Therefore,
Open the lid 3, take out the bag and dispose of it as appropriate.

FIG. 2 shows another embodiment, in which the same structures as in the previous embodiment are given the same reference numerals. The difference from the previous embodiment lies in the pressure receiving surface 18 of the piston 16. That is, the pressure receiving surface 18 is disposed within the bellows 17 with the peripheral end 18' projecting upward. Therefore,
A vertical groove 22 facing the cylindrical wall 11 is formed in the peripheral end portion 18' and the peripheral wall 19' of the pressing surface 19.

Thus, as the piston 16 moves up and down, the groove 22
fits into the cylindrical wall 11 and guides the vertical movement. Moreover, by positioning the pressure receiving surface 18 at the upper part, the vertical dimension within the working chamber 1 can be shortened.

In this way, in this embodiment, since the pressure receiving surface 18 having a relatively large surface area is provided with the pressure surface 19 having a small area, it is possible to increase the surface pressure on the pressing surface 19, that is, the compressive force, and it is possible to achieve a relatively small size. Even if the vacuum device 8 is used, garbage etc. can be reliably compressed.

(g) Effects of the invention According to the invention, compressive force for garbage, etc. can be easily obtained, and the device can be made smaller.
