Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for suitably treating raw kitchen waste discharged from a kitchen for home use or a kitchen for eating and drinking, and more particularly to an apparatus for treating kitchen waste directly connected to a drain hole of a sink.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally known as a garbage disposal device directly connected to a sink is, for example, Japanese Utility Model Laid-Open No. 2-97454, Japanese Utility Model Laid-Open No. 3-47039, Japanese Patent Laid-Open No. 3-181343, Japanese Patent Laid-Open No. 102749. There are proposals such as JP-A-3-65254 and JP-A-3-65255. The technical tendency common to the devices disclosed in the respective publications is that the kitchen is provided with an input port for kitchen waste that is connected to the sink, a screw that is rotationally driven by a motor is installed in the casing, and the supplied kitchen waste is screwed. The water is squeezed to squeeze the water to dehydrate it, and the crushing blade cuts the garbage into small pieces and conveys them to the dust box. The basic structure of the dust box is to collect the treated garbage in a preset garbage bag and prepare for dumping until it is full. However, as in Japanese Utility Model Laid-Open No. 2-97454, there is a technique in which kitchen waste is simply dehydrated and sent, and sent to a dust box without being crushed.

FIG. 10 shows a conventional example of a garbage processing device having such a basic structure. A casing 4 is arranged by directly connecting the kitchen throwing port 3 to the drainage hole 2 of the sink 1, and a strainer 5 by a filter cylinder is provided in the casing 4, and in the strainer 5, the screw 6 is rotationally driven by a motor. Therefore, when raw kitchen waste containing water as shown by the arrow G is thrown in through the drainage hole 2, the kitchen waste is squeezed by the screw 6 to squeeze the water content, dehydrated and crushed by a crushing blade (not shown). Cut the kitchen waste g into small pieces and transport them to the dust box. The dehydrated water passes through the strainer 5 as shown by the arrow w, is collected in the lower drain tank 7, and is drained from the drain trap 8. Also, in the dust box, the treated garbage is collected in a preset garbage bag and prepared for disposal until it is full.

[0004]

[Problems to be solved by the device]

 By the way, what is common to the conventional structure of FIG. 10 and the devices of the above-mentioned publications is that the raw kitchen waste containing a large amount of water is put into the strainer 5 from the drain hole 2 together with the raw kitchen waste. Is to be thrown into. In order to drain the kitchen waste by squeezing with the screw 6 and convey it to the dust box, the strainer 5 needs to be set to a minimum length L1 capable of performing required drainage. Therefore, the stroke length of the screw 6 must be expected to be large, and there is a problem that the device becomes large.

Further, in terms of usability, when kitchen waste containing a large amount of water is thrown in from the drain hole 2 at a time, the treatment in the initial device cannot catch up and water flows backward and overflows from the drain hole 11. There are also inconveniences such as taking out.

Therefore, an object of the present invention is to allow moisture contained in kitchen waste to escape to the outside without passing through the dehydration / conveyance unit, reduce the processing load of the dehydration / conveyance unit, shorten the unit axial length, and downsize the device. Further, it is an object of the present invention to provide a kitchen waste processing apparatus which can appropriately cope with a large amount of kitchen waste being thrown in to some extent without water overflow.

[0007]

[Means for Solving the Problems]

 In order to achieve this object, the kitchen waste disposal apparatus according to the present invention is, in claim 1, a dehydration transportation unit for squeezing and dehydrating the kitchen waste dropped from a drainage hole of a sink, and a dehydration transportation unit. A drain tank for collecting the water dehydrated by the above, and a kitchen which is attached to the dehydration transport unit capable of supplying kitchen waste and has a perforated cylindrical body smaller than the inner diameter of the drain hole and through which the water can pass. An introduction filter is installed in the drain hole.

Further, according to the second aspect of the present invention, the garbage introduction filter is formed into a conical tube shape, and the large-diameter bottom edge of the conical tube shape is closely attached to the upper end of the drainage hole to form a taper between the drainage hole and the drainage hole. It is also possible to provide a gap.

[0009]

[Action]

 According to the first aspect of the present invention, the raw kitchen waste produced by cooking in the sink is dropped together with the water from the drain hole toward the kitchen processing apparatus. Most of the water contained in the kitchen waste is made to flow from the kitchen waste introduction filter into the gap between the drainage hole and escaped to the drain tank from outside the dehydration transport unit, reducing the processing load on the dehydration transport unit.

Further, according to the present invention, the kitchen waste introduction filter has a conical cylindrical shape, and the large-diameter bottom edge of the conical cylindrical shape is closely contacted with the upper end of the drainage hole to form a tapered gap between the drainage hole and the drainage hole. With the provision of the above structure, water can be smoothly discharged between the garbage introduction filter and the drain hole, and untreated garbage pieces do not enter the gap.

[0011]

【Example】

 Hereinafter, an embodiment of the garbage processing apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a partial cross-section of an example in which the garbage treatment device of the embodiment is housed in a system kitchen including a sink and a cooking table of a domestic kitchen, and FIGS. 2 to 4 are the garbage treatment device of the embodiment. FIG. 4 is a plan view, a left side view and a right side view of FIG. In FIG. 1, a garbage disposal device 20 can be easily connected to the drain hole 11 provided in the sink 10. A dewatering / conveying unit 30 is mounted in a casing 21 that constitutes the main body of the garbage processing device 20.

As is clear from FIG. 5, the dehydration / conveyance unit 30 is a portion that conveys kitchen waste that has been thrown in through the drainage holes 11 while dehydrating it, and is made of a light metal such as aluminum or a synthetic resin material such as vinyl chloride or a corrosion resistant material. A compression block 31 formed of stainless steel or the like, which has excellent properties, and a strainer 32 in the form of a filter (which may be made of punch metal) are connected to a cylindrical body to form the main body of the unit. A garbage introduction filter 36, which is directly connected to the drain hole 11, is provided so as to project upward from the compression block 31. A screw 33 spirally processed on the longitudinal axis of the cylinder is rotatably supported in the main body of the unit, and is rotationally driven from a motor 34 via a transmission belt 35 at one end of the rotary shaft.

Here, as shown in FIG. 6, the garbage introduction filter 36 is formed into a cylindrical shape by using, for example, a punch metal having a large number of small holes, and is inserted into the drain hole 11 of the inner diameter d 1 provided in the sink 10. It has an outer diameter d2 of only. That is, d1> d2, and a gap 12 is formed between the drainage hole 11 and the garbage introduction filter 36, and this gap 12 is sufficient for water passage, and is a suitable setting such that only solid garbage cannot enter. Has been done. In addition, it is preferable that the garbage introduction filter 36 has a structure that can be easily attached to and detached from the compression block 31 and can be replaced in consideration of the possibility that clogging will occur in the future in the stage of repeated use. At the joint between the compression block 31 and the garbage introduction filter 36, a water drain hole 37 is provided on the drainage hole 11 side or the casing 21 side of the sink 10, and the water from the gap 12 is drained from this water drain hole 37 to the compression block 31. It can be leaked to the outside.

The compression block 31 has a semi-cylindrical shape and has coupling flanges 31a at both ends, and corrugated compression blades 31b are provided radially on the inner peripheral surface at regular pitches with respect to the axis. That is, by rotating the screw 33, the kitchen waste is crushed into appropriate small pieces by the pressing blade 31b. Like the compression block 31, the strainer 32 is formed in a semi-cylindrical shape with a material that is particularly resistant to corrosion and has a corrosion resistance, and is provided with a large number of filter holes 32a so that water in the garbage can be filtered. At both ends, flanges 32b for coupling with the compression block 31 are provided. The rectangular bar 32c is attached to a part of the circumference of the strainer 32 in the direction of the longitudinal axis, and by using this as a squeezing blade, crushing during filtration and dehydration becomes effective.

The kitchen waste containing water dropped from the kitchen waste introduction filter 22 is conveyed from the upstream side on the right side of the drawing to the downstream side on the left side by rotation of the screw 33 while being squeezed and squeezed to remove water. It will be. In order to prevent water from flowing back to the upstream side, that is, the introduction side, during crushing transportation, the entire axis of the dehydration transportation unit 30 including the rotation axis of the screw 33 should be higher on the downstream side than on the upstream side. It is inclined.

Further, below the dehydration / transport unit 30, a drain tank 40 for storing water dewatered by squeezing of garbage in the dehydration / transport unit 30 is arranged. As shown in FIG. 5 again, the drain tank 40 has a top plate 41, which is joined to the flanges 31a and 32b of the dehydration transport unit 30 and is partitioned. The top plate 41 is provided with, for example, a water drainage groove 42 formed by a long hole so that water in the kitchen waste that has escaped to the outside of the dehydration transport unit 30 through the kitchen waste introduction filter 36 can be directly collected from the water drainage hole 42 into the drain tank 40. It has become. A drain trap 42 is provided on the bottom plate of the tank, and drainage from the kitchen waste is drained. A cutting device (not shown) that cuts the dehydrated kitchen waste into small pieces is arranged downstream of the rear end of the dehydration transport unit 30, and the kitchen waste that is cut here is discharged from the discharge port 38. It has become so.

On the other hand, as shown in FIGS. 1, 8 and 9, a deodorizing unit 50 is arranged so as to face the discharge port 37 of the dehydration / conveyance unit 30. The deodorizing unit 50 has, for example, a small-sized sirocco fan-type blower 51 that rotates by power, and a cartridge-type filter 54 is easily attached to and detachable from the blower 51 via a one-touch fitting type joint portion 57. Are combined. As shown in FIG. 9, the blower 51 has a fan 52, sucks the inside of the lower filter 54 to generate ventilation, and from the exhaust port 53 to the slit-shaped duct 25 (FIG. 3) provided on the side surface of the casing 21. It is designed so that it can be exhausted outdoors. The filter 54 has a cylindrical shape as a whole and has a large number of ventilation holes 55, and is filled with a deodorant 56 such as activated carbon that adsorbs and deodorizes odorous components. Therefore, by driving the air blower 51, ventilation is generated, the kitchen waste dehydrated from the dehydration / conveyance unit 30 and crushed into small pieces is dried, and the odor is sucked through the filter 54 to activate the offensive odor to the activated carbon. It is possible.

It is preferable that the deodorizing unit 30 is disposed as far downstream as possible in the garbage processing passage, that is, the conveying passage. The reason for this is not only to absorb the offensive odor generated from the dewatered and crushed garbage that is being stored in the dust bag of the dust box 60 described below and to ventilate and dry it, but also to perform forced suction by the operation of the blower 51 to the dewatering transport unit 30. This is because, by forcing the water to pass through the drainage hole 11 to the above-mentioned kitchen waste introducing filter 36, which is the main part of the present invention, the kitchen waste being dehydrated and crushed can be deodorized and dried by aeration.

A dust box 60 is arranged below the dewatering / conveying unit 30 and the deodorizing unit 50, and a certain amount of garbage that has been dehydrated from the dewatering / conveying unit 30 and then cut is stored to prepare for dumping. In this system, a dust bag is set in the dust box 60, and the deodorizing unit 50 deodorizes the offensive odor generated from the garbage that has been dehydrated and crushed while being stored in the dust bag.

As shown in FIG. 1 to FIG. 4, the rotary leg 71 and the caster 72 are attached to the bottom plate of the garbage disposal device 20, and the caster 72 is moved around the rotation leg 71 to move the entire garbage disposal device 20. It is also possible to adopt a moving structure that swings around. As a result, as shown in FIG. 1, when the storage space for the garbage processing device 20 is narrowly restricted in the system kitchen, it is not necessary to allow for an extra space for loading and unloading the dust box 60.

Next, the usage mode and operation of the garbage processing device according to the above-described embodiment will be described.

In the sink 10, raw kitchen waste produced by cooking is dropped from the drain hole 11 toward the kitchen treatment device 20 through the kitchen introduction filter 36 together with water. At this time, as is apparent from FIGS. 5 and 6, the water content of the kitchen waste passes through the kitchen waste introduction filter 36, flows into the gap 12 with the drainage hole 11 in the lower portion, and flows out from the water drain hole 37. The outflowing water does not enter the dehydration transporting unit 30, flows along the outer surface of the compression block 31, and is collected inside the tank through the drainage groove 42 provided in the top plate 41 of the drain tank 40.

However, a certain amount of the water content of the kitchen waste originally dropped on the garbage introduction filter 36 flows directly into the dewatering / conveying unit 30, but the amount thereof is small compared with the water content escaping outside the compression block 31. I can say. The processing load on the dehydration / conveyance unit 30 is greatly reduced by the amount of water that escapes to the outside of the compression block 31.

In the garbage processing device 20, the screw 33 of the dehydration / conveyance unit 30 is operated by receiving the rotational drive from the motor 34 by the transmission belt 35. In synchronization with this, an activation signal is also sent to the deodorizing unit 50, and the blower 51 operates. In the unit body of the cylindrical body formed by the compression block 31 and the strainer 32, the kitchen waste containing the water introduced from the kitchen waste introduction filter 36 is directed from the upstream side to the downstream side by the rotation of the screw 33, and is compressed by the compression blade 31b. It is transported while being squeezed and then crushed into appropriate small pieces. As described above, the processing load during this period is reduced by the amount of water that has escaped to the outside of the compression block 31. In the strainer 32, the water content of the kitchen waste is filtered through a large number of filter holes 32a, and the dehydration transport unit 30 is forcibly ventilated by suction by the operation of the blower 51, and both the deodorization and ventilation drying of the kitchen waste during dewatering and crushing are performed. Is suitable. The water filtered by dehydration is stored in the drain tank 40 below. The drain is drained from the drain trap 42 on the bottom plate of the tank.

The garbage that has been dehydrated, crushed into small pieces, and deodorized to some extent during this time as well as being aerated and dried is thrown into the dust box 60 below from the discharge port 37 on the downstream side of the rear end of the dehydration transport unit 30, and a fixed amount is stored. Prepare for dumping. A dust bag is set in the dust box 60, and the garbage is deodorized by the deodorizing unit 50 also while being stored in the dust bag.

That is, during storage in the dust bag of the dust box 60, ventilation is generated by driving the sirocco fan type blower 51 of the deodorization unit 50, and the kitchen waste dehydrated from the dehydration transport unit 30 and crushed into small pieces is further dried by ventilation. . At the same time, the odor of garbage is sucked through the filter 54, and the offensive odor is attached to the activated carbon. Thus, in the dust box 60, spoilage is prevented by air-drying the kitchen waste and deodorizing the offensive odor. It can be stored without decay until the garbage bag is filled with a certain amount of kitchen waste. If it is determined that the deodorizing unit 50 has a weak effect of absorbing offensive odors, the filter 54 is a cartridge type, so it can be easily removed from the blower 51 side and the deodorant such as activated carbon filled inside can be replaced with a new one. Exchange.

When the full garbage bag is taken out from the dust box 60 and is thrown away, the caster 72 is moved by using the entire garbage disposal device 20 with the rotation leg 71 as a fulcrum of rotation, and the garbage disposal is performed as shown by a virtual line in FIG. Swing the entire device 20 and slide it from the system kitchen.

Since the garbage stored in the dust bag of the dust box 60 has been dehydrated, crushed into small pieces, deodorized, and aerated and dried, the weight and volume at the beginning are remarkably light and bulky. Therefore, the work of taking out dust is very simple and reduced.

In contrast to the above embodiment, FIG. 7 shows another embodiment of the garbage introduction filter which is the main part of the present invention. That is, in the case of the garbage introduction filter 80 of the second embodiment, the material is the same as that of the above-mentioned garbage introduction filter 36, the shape is an inverted cone, and the bottom is in contact with the drain hole 11. A tapered gap 81 is formed between the drain hole 11 and the drain hole 11. With such a shape, there is an advantage that the upper end of the drainage hole 11 is closed and the small solid kitchen waste can be completely prevented from entering the gap 81 at the beginning of charging.

[0031]

[Effect of device]

 As described above, in the kitchen waste disposal apparatus according to the present invention, in the first aspect, most of the water contained in the kitchen waste is drained from the kitchen waste introduction filter to the gap between the drainage holes for dehydration conveyance. By letting it escape from the outside of the unit to the drain tank, the processing load on the dehydration transport unit can be reduced and the dehydration transport unit can be made smaller, and even if a large amount of waste is thrown in at one time, the water in the kitchen waste will be drained. It is prevented from flowing back and overflowing.

Further, according to the second aspect, since the tapered gap with the upper end closed is provided between the kitchen waste introduction filter and the drain hole, there is an advantage that untreated kitchen waste pieces do not enter the gap. is there.
