[0002]

[Prior art]

 2. Description of the Related Art Conventionally known garbage disposal devices directly connected to a sink include, for example, Japanese Utility Model Publication No. 2-97454, Japanese Utility Model Publication No. 3-47039, Japanese Patent Application Laid-Open No. 3-181343 and Japanese Patent Application Laid-Open No. 2-102749. There are proposals such as Japanese Patent Laid-Open No. 3-65254 and Japanese Patent Laid-Open No. 3-65255. The technical tendency common to the devices disclosed in each publication is that the kitchen inlet of the kitchen connected to the sink is provided in the device's casing, and a cylindrical filter strainer with many small holes is arranged in the casing. The screw is rotatably supported by the drive of the motor in the strainer. Therefore, the kitchen waste introduced into the strainer from the charging port is squeezed by the screw to squeeze the water to dehydrate the kitchen waste and cut the kitchen waste into small pieces with the crushing blade and convey them to the dust box. The dewatered kitchen waste water passes through the strainer and is collected in the lower drain tank. The basic structure of the dust box is to collect the processed garbage in a preset garbage bag and prepare for dumping until it becomes full.

For example, in the case of the device disclosed in Japanese Patent Laid-Open No. 3-181343, a feed spiral is provided at the front and back with the porous partition plate sandwiched between them, that is, before the porous partition plate, that is, at the porous partition plate and the rear feed spiral. A cutting blade is placed between them. Therefore, the kitchen waste sent by the rearward feed spiral is cut by the cutting blade, the cut one is passed through the perforated partition plate, and after passing, the dehydrated treated kitchen waste is compressed and dehydrated by the frontward feed spiral. Discharge from the outlet.

Further, in the devices disclosed in JP-A-3-65254 and JP-A-3-65255, the thrown garbage is received by a rotating plate equipped with a crushing blade, and the crushing garbage is disposed by a draining drum arranged in another part. It is designed to remove water and drain.

However, as disclosed in Japanese Utility Model Application Laid-Open No. 2-97454, there is also a technique in which kitchen waste is simply dehydrated and sent, and sent to a disposer without crushing.

[0006]

[Problems to be solved by the device]

 By the way, one of the ways to maintain a suitable environment in a home kitchen or a commercial kitchen is a problem of offensive odor caused by the decay of kitchen waste attached to the drainage pipe system. In the garbage treatment equipment, crushing and cutting is performed in the processing process, so kitchen waste and chips adhere and remain at these cutting parts, and when they decompose, they emit offensive odors and offensive odors to the surrounding area. In terms of purification of domestic wastewater, the attached and decomposed kitchen waste causes pollution of the wastewater.

On the other hand, the wastewater from the garbage treated by the garbage treatment device is separated from the wastewater because the liquid discharged from the garbage becomes contaminated wastewater when the kitchen waste containing a large amount of water is crushed while being squeezed and dehydrated. Preferably. In order to separate the dehydrated water and the juice, it is possible to obtain a squeezing pressure so that the juice can be only dehydrated when the kitchen waste is squeezed. It is also possible to limit the amount of squeeze by setting a moderate size without excessively crushing and cutting the garbage. However, if the chopped kitchen waste is too large, it will be difficult to discharge it, and there will be an effect such as inconvenience in collecting it in the dust box.

With respect to the above points, in the case of the technologies of any of the publications including the above-mentioned JP-A-3-181343, JP-A-3-65254 and JP-A-3-65255, the respective means are provided. As a result, the water removed from the garbage is mixed with the juice that comes out during crushing and cutting, and then drained into the sewage.

However, in Japanese Unexamined Patent Publication (Kokai) No. 3-181343, as described above, the chopped kitchen waste is passed through the perforated partition plate. Therefore, this is perforated while cutting with a cutting blade, as seen in a minced meat machine. A large amount of juice is discharged by passing it through a diaphragm, and this is drained together with dehydrated water. Moreover, since the scraps of garbage easily adhere to the perforated partition plate, and if it perishes, it causes a bad odor, which makes maintenance even more troublesome.

In Japanese Patent Laid-Open No. 3-65254 and Japanese Patent Laid-Open No. 3-65255, it is considered that the juice is drained together with the dehydrated water. It is hard to say that it has been taken into consideration even with the problem of chip attachment and decay. Moreover, in both of these publications, since the mechanism for receiving and discarding the dumping waste by the rotating plate with the crushing blades arranged at a considerably high speed located below, the noise vibration during processing is high, and the entire device is very complicated. Therefore, the equipment cost is high, and it is difficult to introduce it to the home especially in terms of cost.

[0011] Therefore, a main object of the present invention is to provide a garbage treatment device capable of preventing a bad odor caused by attachment and rotting of garbage and maintaining a preferable environment and reducing maintenance, and at the same time, during the compression dehydration. It is an object of the present invention to provide a kitchen waste treatment device which is effective in suppressing drainage of juice and cleaning domestic wastewater, and further can reduce noise and cost.

[0012]

[Means for Solving the Problems]

 In order to achieve this purpose, the kitchen waste disposal device according to the present invention is arranged so as to face the end of a screw that conveys kitchen waste introduced from the drainage hole of the sink and squeezes it to dehydrate it, and cuts the kitchen waste after dehydration. And a scraper that is rotatably supported on the rotating shaft of the screw and that is disposed in sliding contact with the discharge port of the garbage cutting device.

[0013]

[Action]

 The kitchen waste that has been cut by the kitchen cutting device is discharged from the discharge port. At this time, the scraps and debris of the kitchen waste attached to the discharge port are scraped off by the scraper. The scraper also has a function of cutting the kitchen waste that cannot be completely cut, as an auxiliary member of the kitchen cutting device.

[0014]

【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 partial cross-sectional front view of an example in which the kitchen waste processing apparatus 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 kitchen waste processing of the embodiment. It is the top view, left side view, and right side view of an apparatus. In FIG. 1, a garbage disposal device 20 can be easily connected to the drain hole 11 provided in the sink 10, and a dewatering / conveying unit 30 is installed in a casing 21 constituting the main body of the garbage disposal device 20. There is.

As is clear from FIGS. 5 and 6, the dehydration / conveyance unit 30 is a portion that squeezes and dewaters the garbage thrown from the drainage hole 11 to convey the garbage, and a light metal such as aluminum or a synthetic resin such as vinyl chloride. Material, or a semi-cylindrical upper compression block 31 formed of stainless steel or the like having excellent corrosion resistance, and a semi-cylindrical lower strainer (perforated filter section) 34 to form a cylindrical cylinder. ing. A screw 36 spirally processed as shown in FIG. 1 is rotatably supported inside the cylinder, and one end of the rotary shaft decelerates the rotational drive from a motor 38 to a required rotation ratio and a transmission belt. It is supposed to be received via 39. The squeeze block 31 has a kitchen waste introduction portion 37 protruding upward, and this kitchen waste introduction portion 37 can be directly connected to the drainage hole 11 with a sealing property by projecting it upward from the casing 21.

In the pressing block 31 of the dehydration transport unit 30, as shown in FIG. 6, a ridge 32a and a valley 32b are alternately arranged along the inner peripheral surface of the semi-cylindrical surface at regular intervals. A corrugated kitchen waste compressing portion 32 is provided so as to extend in the axial direction of the cylinder, and by cooperation with the kitchen waste compressing portion 32, the kitchen waste compressed by the screw 36 can be guided in the axial direction. The axial end of the squeeze block 31, that is, the downstream end in the direction of propulsion by the screw 36, is a discharge part that pushes out the kitchen waste that has been compressed, and here is a kitchen that cuts the dehydrated kitchen waste into more appropriate small pieces. A cutting device 80 is provided. Flange 33a is provided at both ends of the semi-cylindrical shape of the compression block 31 so that it can be bolted to the strainer 34.

The lower strainer 34 is formed into a semi-cylindrical shape by using, for example, punch metal, or is formed into a semi-cylindrical shape from a material that is particularly resistant to corrosion like the compression block 31 and has a large number of filters. It has a hole 34a. Through this filter hole 34a, the water content of the kitchen waste squeezed and dehydrated by the screen 36 can be discharged to an external drain tank 40 described later. Flange 34b for coupling with the compression block 31 is provided at both ends. Further, by attaching one or more thin guide bars 35 inside the strainer 34 in the longitudinal axis direction, it is effective in increasing the rigidity of the strainer 34 itself, guiding the garbage, and assisting the crushing of the garbage in the squeeze block 31. Target.

Here, as shown in FIG. 1, the screw 36 has a spiral pitch of P1, P2, P3, ... Pn from the upstream end on the right side to the downstream end on the right side in the figure close to the garbage introduction part 37. It is changing gradually small. By setting the shape of the screw 36 in this way, it is possible to suitably set the compression pressure for the garbage at the initial stage of feeding the garbage and the stage at which the feeding proceeds. In addition, the compression can be controlled from the initial stage to the final stage with respect to the garbage, and the cylinder including the strainer 34 can squeeze only the water without discharging the juice in the garbage. Also, the rotation mode of the screw 36 is controlled by alternating forward and reverse rotations, such as two rotations for forward rotation and one rotation for reverse rotation, so that squeezing against garbage is more effective and clogging of garbage is achieved. Very effective in prevention.

Therefore, with such a configuration of the dehydration / conveyance unit 30, the kitchen waste containing the water introduced from the kitchen introduction section 37 is moved from the upstream side on the right side to the downstream side on the left side in FIG. 1 by the rotation of the screw 36. On the other hand, the water will be drained by squeezing and will be squeezed and transported. In order to prevent water from flowing back to the upstream side, that is, the introduction side, during conveyance, the axis of the entire dehydration / conveyance unit 30 including the screw 36 is inclined so that the downstream side is higher than the upstream side.

FIGS. 7 to 9 show the essential part of the present invention, namely, the garbage cutting device 80 provided at the downstream end of the screw 36 and the scraper 90 which should also be called this auxiliary member. That is, a partition wall 25 for partitioning the inside of the casing 21 is provided, and the rotary blade 81 is attached to the front side screw 36 side so that the rotary blade 81 is flush with the terminal end twisted surface as much as possible. It rotates together with 36. The rotary blade 81 is made of, for example, corrosion-resistant stainless steel, has a thin flat shape, and is fixed with countersunk screws 82. Further, the partition wall 25 is provided with, for example, a rectangular opening window 26, and a plate 83 for a fixed blade is attached thereto. The plate 83 is radially provided with a plurality of fixed blades 84 centered on the extension of the rotation axis of the screw 36, that is, the rotary blade 81. In the embodiment, the fixed blade 84 is formed by punching, for example, four blades having an angle pitch of 90 degrees. An inner corner of each fixed blade 84 is a portion that becomes a shearing blade edge with the rotary blade 81. A space between the adjacent fixed blades 84 is opened as a fan-shaped space, and this space serves as an outlet 85 for the cut kitchen waste. A shaft hole 86 is provided at the center of each fixed blade 84, and a shaft 87 protruding from the end surface of the screw 36 is inserted into the shaft hole 86. The tip of the shaft 87 is made into a bolt shape, and a nut 88 is screwed into it to attach the plate 83 for the fixed blade to the partition wall 25. The rotary blade 81 is also inserted through the shaft 87.

In FIGS. 7 and 8, the scraper 90 is arranged on the rotation shaft of the garbage cutting device 80 and can rotate integrally with the screw 36 and the rotary blade 81. For example, as in the illustrated example, angle type steel or the like is used to fasten the shaft 87 together with a nut 88. In this case, the rotary blade 81 and the fixed blade 84 are arranged at angular positions deviated from each other, and the scraper 90 is arranged at a position further shifted in angle with respect to both blades 81 and 84 due to the shearing. In order to mount the scraper 90 at a predetermined angle position, a key groove 92 is provided in a mounting hole 91 through which the shaft 87 is inserted, a key groove 87a is also provided in the shaft 87, and a key 93 is fitted into both the key grooves 92 and 87a. I am letting you. In order to position the scraper 90, there are various means such as a spline and a serration fitting method in addition to the key 93. The scraper 90 having an L-shaped cross section has its one side surface brought into contact with the plate 83 having the fixed blade 84 from the outside, and is rotated in the same direction as the rotary blade 81 along with the screw 36 so that the scraper 90 can slidably contact the plate 83. There is.

Further, in order to improve the assembling property and the mounting strength of the plate 82 with respect to the partition wall 25, it is preferable to provide a frame 27 or the like along the opening edge of the partition wall 25 as shown in FIG. Further, as shown in FIG. 8, the rotary blade 81 fixed by the countersunk screw 82 so as to be substantially flush with the terminal twisted surface of the screw 36, has both end surfaces subjected to R processing with an appropriate curvature. desirable. This prevents kitchen chips and debris from accumulating during shearing with the fixed blade 84. Both end corners are preferably subjected to heat treatment so as to have durability as a cutting edge. As described above, in a mode in which the rotation of the screw 36 is repeated forward and backward, the R processing and heat treatment of the rotary blade 81 may be performed only on one end surface.

On the other hand, below the dewatering / conveying unit 30, a drain tank 40 is arranged to temporarily collect and then drain the water dewatered by squeezing the garbage. As shown in FIG. 5, the drain tank 40 has a top plate 41, and the top plate 41 is connected to the dehydration / conveyance unit 30 and the flanges 33a and 34b of the strainer 34 for partitioning. A drain trap 42 is provided on the tank bottom plate, and drainage from the kitchen waste can be drained.

In the embodiment, the rotary leg 71 and the casters 72 of an arbitrary number can be attached to the bottom of the casing 21 in preparation for retrofitting the kitchen waste treating apparatus 20 to the existing system kitchen. Therefore, as shown in FIG. 1, the garbage disposal device 20 can be swung around by moving the casters 72 around the rotation legs 71 as a rotation center and pulling them out from the system kitchen. Accordingly, when the storage space for the garbage processing device 20 is narrowly restricted in the system kitchen, it is not necessary to allow for extra space for loading and unloading the dust box 60.

In addition, in the embodiment, as shown in FIG. 1, it is possible to dispose the deodorizing unit 50 so as to face the garbage cutting device 80. 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 replaceably coupled to the blower 51. The blower 51 has a fan and is capable of sucking the inside of the lower filter 54 to generate ventilation and exhaust from the exhaust port. 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 such as activated carbon that adsorbs and deodorizes odorous components. Therefore, it is possible to generate ventilation by driving the blower 51, dry the kitchen waste dehydrated from the dehydration transport unit 30 and crushed into small pieces, and suck the odor through the filter 54 to adsorb the offensive odor to the activated carbon. .

When the deodorizing unit 50 is installed, it is preferable that the deodorizing unit 50 is arranged on the downstream side of the garbage processing passage, that is, the conveying passage. The reason for this is not only to absorb the offensive odor generated from the dehydrated and crushed kitchen waste that is being stored in the dust bag of the dust box 60 described below and to ventilate and dry it, but also to force the dehydration transport unit 30 to perform forced suction by the operation of the blower 51. The reason is that the drainage hole 11 can be forced to reach the garbage introduction portion 37, whereby the garbage that is being dehydrated and crushed can be deodorized and dried by aeration.

Below the deodorizing unit 50, below the discharge port 85 of the above-mentioned garbage cutting device 80, a dust box 60 is arranged, and a certain amount of the treated garbage discharged from the dehydrated and cut discharge port 85 is collected and discarded. To prepare for. A dust bag is set in the dust box 60, and the offensive odor generated from the garbage that has been dehydrated and crushed during storage in the dust bag can be deodorized by the deodorization unit 50.

Next, a usage mode and an operation of the garbage processing apparatus according to the above embodiments will be described.

In the sink 10, raw kitchen waste produced by cooking is dropped together with water from the drain hole 11 toward the kitchen processing device 20 through the kitchen introducing section 37. In the garbage processing device 20, the screw 36 of the dehydration / conveyance unit 30 operates by receiving the rotational drive from the motor 38 by the transmission belt 39. In synchronization with this, if the deodorizing unit 50 is installed, a start signal is also sent to the deodorizing unit 50, and the blower 51 operates.

In the cylinder composed of the compression block 31 and the strainer 34, the kitchen waste containing water introduced from the kitchen introduction section 37 moves from the upstream side to the downstream side by the rotation of the screw 36, and cooperates with the kitchen compression section 32. It is squeezed by the work without clogging the kitchen waste, only water is squeezed and dehydrated. The dehydrated water is discharged from the strainer 34 in the lower half of the cylinder through a number of filter holes 34a, and is stored in the drain tank 40 below. The drain is drained from the drain trap 42 on the bottom plate of the tank. However, while the juice of the kitchen waste is squeezed to some extent during the pressing by the screw 36, it is extremely small compared to the dehydration and does not contaminate the sewage drainage from the drain tank 40.

Since the spiral pitch of the screw 36 is gradually reduced, not only the drainage function of the kitchen waste but also a large amount of kitchen waste is thrown from the kitchen introduction portion 37 at one time, the screw 36 initially bears a large load. It has the meaning of not applying.

The garbage that has been dehydrated and conveyed by the dehydration / conveyance unit 30 is then cut into an appropriate size by the garbage cutting device 80. That is, the kitchen waste reaching the end of the screw 36 is sheared by the rotating blade 81 and the fixed blade 84 on the plate 83 side. The size of the kitchen waste to be sheared is such that it can be discharged from the discharge port 85, and it is neither too large nor too small, and because of too little shearing, a large amount of juice-like juice is suppressed from the kitchen waste. . Since the rotary blade 81 and the fixed blade 83 constitute a pair of shearing blades that are in close contact with each other, almost no garbage or clogging of garbage is found around the cutting portion as in the prior art. In shearing with the rotary blade 81, the optimum number of the fixed blades 84 in the plate 83 is four with an angular pitch of 90 degrees as a result of the trial experiment.

During the cutting of the garbage by such shearing, in the plate 83 of the fixed blade 84, the cut chips and dusts of the cut garbage adhere to the periphery of the cutting edge of each fixed blade 84 and the surface of the plate 83. There is. The attached chips and the like are efficiently scraped off by the scraper 90 rotating simultaneously. Further, even if the kitchen waste happens to pass without being cut by the rotary blade 81 and the fixed blade 84, which are a pair of shearing blades, it is cut again by the outer scraper 90. In this sense, the scraper 90 is a member that has not only a scraping function of scraps but also a function as an “outer blade” that assists the garbage cutting device 80.

FIG. 10 shows another embodiment of the garbage cutting device 80. In this case, the scraper 90 having an L-shaped cross section is attached to and brought into contact with the plate 83 in a posture different from that of the previous embodiment shown in FIG. In this case, the scraper 90 is stabilized by the positioning nut 89 from the inside. The obtained effect is similar to that of the above-mentioned embodiment. Corresponding members are assigned the same reference numerals and explanations thereof are omitted.

By the way, even during the processing by the garbage cutting device 80 and the scraper 90, the garbage is deodorized by the deodorizing unit 50 and dried by aeration, which is suitable for the liquid juice. It is dropped from the discharge port 85 of the garbage cutting device 80 to the lower dust box 60, and a certain amount of it is collected and prepared for disposal. A dust bag is set in the dust box 60, and the processed garbage is stored in the garbage bag.

When a 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 rotation fulcrum, and the garbage disposal is carried out as indicated by a virtual line in FIG. The entire device 20 can be swung around and slid from the system kitchen, making it easy to change the garbage bag in a large space.

Further, since the kitchen waste stored in the dust bag of the dust box 60 is 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.

[0039]

[Effect of device]

 As described above, in the garbage disposal device according to the present invention, the garbage cut by the garbage cutting device is discharged from the discharge port, and the scraps and debris of the garbage attached to the discharge port are scraped off by the scraper. As is conventionally seen in this type of device, the spoilage and debris attached to the cutting portion at the cutting portion can be eliminated, and a suitable environment free from offensive odors and offensive odors can be maintained.

In addition, according to the present invention, since the kitchen waste dehydrated by the screw can be cut by the rotary blade and the fixed blade so as not to be too small or too small, the amount of the juice can be suppressed to the minimum amount, and not only the purification of the wastewater but also the The mechanism from squeezing to cutting is very simple, and the cost and noise of the device can be reduced.
