Description

Food waste treatment device of the sink {FOOD WASTE TREATMENT APPARATUS FOR SINK}

The present invention relates to a food waste disposal apparatus for a sink, and more particularly, to a food waste disposal apparatus for finely pulverizing food waste collected in a sieve of a sink and neatly removing food waste caught in the sieve.

In general, a large amount of leftover food waste is discharged every day in homes or restaurants.

This food waste is filtered by a strainer installed in the drain of the sink, and the filtered food waste is stored in a separate food waste storage bin and discharged through a food waste bag when a certain amount is stored.

However, there are frequent cases in which food waste is not separated and discharged in a designated food waste bag, but disposed of together with general waste in a garbage bag, etc., and since such food waste contains a large amount of moisture, decay occurs in a relatively short time. In the end, it is pointed out as a major cause of environmental pollution, which causes odor or bad bacteria to breed.

For example, food waste is eaten and thrown away at home or in restaurants. The amount of food waste thrown away per day nationwide is 15,075 tons, equivalent to 1,880 8-ton trucks, accounting for 31.6% of the total household waste. A large amount of food waste is generated.

In particular, since most food waste disposal in Korea relies on landfill, throwing away leftover food as it is unsanitary processing further deteriorates the living environment.

Moreover, in our situation, it is difficult to purchase the land needed for landfill construction, but many residents living nearby exercise their right to resist because they are reluctant to be damaged by odors, dust, leachate pollution, and various pests. Construction has emerged as a social issue.

Therefore, there is an urgent need for a fundamental plan for reducing the absolute amount of food waste discharged while developing an environmentally friendly and economical food waste treatment method.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are perspective views showing a food waste disposal device for a sink according to an embodiment of the present invention, and FIG. 4 is a plan view showing a food waste disposal device for a sink according to an embodiment of the present invention. 6 is a cross-sectional view showing an apparatus for disposing of food waste in a sink according to an embodiment of the present invention.

As shown in FIGS. 1 to 6, the food waste disposal device of the sink has a gear type grinding device 11 installed inside the strainer 10 installed in the sink, and the food waste collected in the strainer 10 is removed. It consists of a structure for processing food waste in a manual method of crushing or cutting by inserting it between the teeth of the gear type crusher 11.

To this end, the gear type grinding device 11 includes a sun gear 13, a planetary gear 14, a planetary gear carrier 15, and a ring gear 16.

The sun gear 13 is installed in a structure fixed to the lower end of the hollow sun gear shaft 12 installed vertically at the center of the bottom of the strainer 10, and the sun gear 13 installed in this way rotates along its circumference. And a plurality of orbiting planetary gears 14 are meshed with each other so that they can turn.

As a preferred embodiment, as shown in FIG. 7, the sun gear 13 may be formed by stacking and combining several plate-shaped gears. For example, about 8 plate-shaped gears having a thickness of about 2 mm After sequentially stacking about 10 to 10 sheets, a plurality of pins can be vertically penetrated and combined integrally.

At this time, in the sun gear 13 formed by stacking several plate-shaped gears, about 1/3 of the upper plate-shaped gear can be stacked so that its teeth are aligned up and down, and about 2/3 of the lower part is plate-shaped. The gears can be stacked so that the teeth of the upper plate gear are stacked so that the teeth are aligned up and down, so that the pitch is 1/2 of the pitch of the upper plate gear, for example, the teeth of the upper plate gear are positioned between the teeth of the upper plate gear. .

Accordingly, when food waste enters the meshing area between the sun gear 13 and the planetary gear 14, even if the food waste at this time is long or flat, it is chewed between the teeth of the sun gear 13 and the planetary gear 14. It is possible to increase the efficiency of crushing treatment of food waste, such as being shredded.

The planetary gear 14 is a gear meshed with the circumference of the sun gear 13 located at the center, and these planetary gears 14 consist of about 3 to 4 pieces and engage with the sun gear 13 to rotate and rotate. will do

As a preferred embodiment, as shown in FIG. 7, the planetary gear 14, like the sun gear 13, can be made in the form of stacking and combining several plate-shaped gears, for example, with a thickness of about 2 mm. After sequentially stacking about 8 to 10 plate-shaped gears, a plurality of pins can be vertically penetrated and integrally coupled.

At this time, in the planetary gear 14 in the form of stacking several plate-shaped gears, the plate-shaped gear constituting the upper upper planetary gear 14a can be stacked so that it and its teeth are aligned up and down, and the lower planetary gear 14b on the lower side ) is formed so that the teeth of the upper plate gear are stacked so that the teeth are aligned up and down, so that the pitch is 1/2 of the pitch of the upper plate gear, for example, so that the teeth of the upper plate gear are positioned between the teeth of the upper plate gear and the teeth of the lower plate gear. can be layered.

Accordingly, when food waste enters the meshing area between the sun gear 13 and the planetary gear 14, even if the food waste at this time is long or flat, it is chewed between the teeth of the sun gear 13 and the planetary gear 14. It is possible to increase the efficiency of crushing treatment of food waste, such as being shredded.

Here, the planetary gear 14 can be rotated around the planetary gear shaft 19 while being supported through and supported by the planetary gear shaft 19 installed vertically in the planetary gear carrier 15.

When the plurality of planetary gears 14 mesh with the sun gear 13 in the middle and rotate in this way, food waste is rolled between the teeth between the sun gear 13 and the planetary gear 14, and can be crushed or cut into small pieces.

The ring gear 16 is the rotation of the ring gear drive shaft 17 connected to the closed/open lid 36, and the rotational force is received as a planetary gear that revolves in the through-fixed shaft of the planetary carrier and is fixed as a reduction ratio by the sun gear. As the force increases, the food is crushed.

With the fixed sun gear 13 in the middle and the plurality of planetary gears 14 engaged, when the handle of the lid is turned, the ring gear rotates by the connecting pin of the ring gear driving shaft, and the fixed sun gear 13 As food waste is rolled between the teeth between the teeth and the planetary gear 14, it can be crushed or cut into small pieces.

In addition, the planetary gear carrier 15 serves to integrally bind each planetary gear 14, and when the planetary gear 14 rotates, it rotates (rotates) along with the sun gear center as an axis be able to

In particular, the planetary gears 14 are composed of one upper and lower pair, respectively, so that they can perform a deceleration function.

To this end, in the planetary gear 14, the upper planetary gear 14a and the lower planetary gear 14b are coaxially arranged on the upper and lower sides of the planetary gear 14 with the upper and lower intermediate planetary gear carriers 15 interposed therebetween. The upper and lower planetary gears 14a and 14b are installed in a structure in which they are rotated together with the planetary gear shaft 19 installed vertically through the planetary gear carrier 15.

Accordingly, as the upper planetary gear 14a and the lower planetary gear 14a rotate while meshing with the upper and lower teeth of the sun gear 13, a reduced rotation at a certain rate can be achieved. As a result, the user can operate the gear-type crusher 11 without effort, such as lowering the operating force for operating the gear-type crusher 11.

Here, the planetary gear 14 and the sun gear 13 as well as the ring gear 16 may be formed of not only spur gears but also helical gears capable of increasing crushing force.

In addition, a backlash may be set between the planetary gear 14 and the sun gear 13, or a rubber bushing (not shown) may be interposed between the planetary gear 14 and the planetary gear shaft 19, Accordingly, there is an advantage in preventing damage to the gears, such as allowing the gears to be flexibly engaged and rotated even when large particles or tough food waste are tightly caught between the teeth between the gears.

The ring gear 16 is an internal gear that is arranged around the planetary gear 14 and meshes with the planetary gears 14 at this time to rotate. It wraps around the upper part of the upper planetary gear 14a and at the same time engages with the upper planetary gear 14a so that it can turn.

That is, when the ring gear 16 is turned, the upper and lower planetary gears 14a and 14b, the planetary gear carrier 15, and the sun gear 12 can rotate in conjunction.

In addition, a ring gear driving shaft 17 formed in a hollow tube shape is vertically formed at a certain height at the center of the upper surface of the ring gear 16, and the ring gear 16 is rotated by turning the ring gear driving shaft 17. By doing so, each gear can engage with each other in connection with this.

At this time, two driving shaft connecting pins 34 are formed at the upper end of the ring gear driving shaft 17, respectively, and the driving shaft connecting pins 34 formed in this way are connected to the cap housing 30 of the cap 31 to be described later. While being inserted into the slot 35 formed in the ), it plays a role of connecting the ring gear drive shaft 17 and the cap 31 to each other.

Such a gear type crusher 11 includes at least one guide wing 18 as a means for driving food waste to the central region of the strainer 10 .

The guide vanes 18 are made in the form of a vertical square plate, and these guide vanes 18 are installed in a structure fixed to the outer circumference of the planetary gear carrier 15 through one side end, and the guide vanes installed in this way ( The other side end of 18) extends to a position close to the inner wall of the strainer 10, and the lower end extends to a position close to the bottom of the strainer 10.

In particular, each of the guide vanes 18 is basically formed radially with respect to the center of the planetary gear carrier 15 and is formed in the form of a curved plate gently curved in the same direction.

Accordingly, when the guide blades 18 are rotated, the food waste in the strainer 10 is naturally guided along the concave surface of the guide blades 18 to the middle area of the strainer 10, that is, the sun gear 13. and the planetary gear 14 are meshed with each other, and eventually, the collected food waste is between the teeth between the sun gear 13 and the planetary gear 14 and between the teeth between the sun gear 13 and the lower planetary gear 14b. It can be broken into small pieces as it gets caught between the teeth.

As another example, the guide blades 18 may be formed in a straight plate shape, in which case the guide blades 18 in the shape of a straight plate may be arranged at an offset angle.

That is, the guide vanes 18 may be formed of an offset angle bent inward at a predetermined angle with respect to the radial direction or an offset angle of a tangent to the outer circumferential surface of the planetary gear carrier 13, and thus the strainer 10 Food wastes on the outer side of the can be naturally gathered toward the center of the strainer 10 on the guide wings 18.

These guide wings 18 also play a role in removing food waste caught in the sieve arc 24 on the inner bottom surface through the lower end in close contact with the inner bottom surface of the sieve 10.

In addition, a plurality of burr grooves 39 are formed at the lower end of the guide blade 18, that is, at the end of the side in contact with or close to the bottom of the strainer 10, and at this time, inside the burr groove 39, the strainer ( The burr 25 of the sieve hole 24 formed at the bottom of 10 can be positioned.

Accordingly, the lower blade portion of the guide wing 18 can adhere to the bottom surface of the strainer 10, and eventually food waste attached to the bottom of the strainer or stuck in the hole of the strainer can be completely removed. In addition, since the food waste can be cut while being caught between the burr groove 39 and the burr 25, the food waste grinding efficiency can be increased.

Here, it is preferable that the number of guide vanes 18 installed is proportional to the number of planetary gears 14 installed.

For example, when 3 to 4 planetary gears 14 are installed, correspondingly, 3 to 4 guide wings 18 may also be installed, and each guide blade 18 installed in this way corresponds to each planetary gear. It is desirable to have one-to-one matching with (14).

That is, the guide vanes 18 can be installed at the location where the planetary gears 14 are installed, and in this way, the food waste guided by the guide vanes 18 and pushed toward the center area is directly connected to the planetary gears 14. It is possible to enter the meshing area between the gears 13.

In addition, the food waste disposal device of the sink is inserted into the inner and outer wall surfaces of the strainer 10 and into the hole 24 formed on the bottom surface of the strainer to remove various types of food waste, and includes rotary blades 23. includes

The rotary blade 23 includes an inner blade 20 for removing food waste attached to the inner wall surface of the strainer 10 and an outer blade for removing food waste attached to the outer wall surface and the outer bottom surface of the strainer 10. It consists of (22).

The inner blade 20 is a combination of a long strip-shaped square bar-shaped horizontal bar and a vertical bar, and is supported by welding on the outside of the planetary gear carrier 15 using the horizontal bar and a sieve using the vertical bar ( It is installed in a structure closely adhered to the inner wall of 10).

These internal blades 20 can scrape the inner wall surface of the sieve 10 while rotating together with the planetary gear carrier 15, and eventually attached to the wall surface of the sieve 10 by the internal blade 20 or the sieve hole Food waste caught in (24) can be removed.

The outer blade 22 is formed by bending a long strip-shaped square bar into a “c” shape, and is supported on the side of the ring gear drive shaft 17 through the blade axis 21 and is formed on the outer side of the strainer 10. It is installed in a structure that closely adheres to the wall surface and the outer floor surface.

For example, the blade shaft 21 is arranged side by side in a coaxial structure inside the ring gear drive shaft 17, and the upper end of the blade shaft 21 at this time is coupled to the ring gear drive shaft 17 and The lower end penetrates the bottom of the strainer 10 and is located on the bottom of the strainer 10, and the middle of the length of the outer blade 22 is coupled to the lower end of the blade shaft 21 located in this way by a fastening structure, so that the outer The blade 22 can be installed in a structure that rotates together with the ring gear drive shaft 17 while being supported by the ring gear drive shaft 17 via the blade shaft 21 .

In addition, the inner blade 20 and the outer blade 22 of the rotary blade 23 form a burr 25 formed in the sieve hole 24 of the sieve 10, for example, perforation of a punch when forming a sieve hole. As a result, food waste stuck in the sieve hole 24 sharply collides with each other while rotating while being in contact with the burr 25 protruding sharply in one direction and rotating to cut and remove the food waste. Internal and external blades ( 20, 22) can easily come out and be removed while being cut or crushed by the blade (end) and the sharp burr 25.

In particular, the inner blade 20 and the outer blade 22 are formed with a plurality of burr grooves 39 disposed at regular intervals in the up and down direction at the ends in contact with the wall surface of the strainer, and within the burr groove 39 thus formed. As the burr 25 in the sieve hole 24 of the sieve 10 is located, the blade parts of the inner and outer blades 20 and 22 can be in close contact with the wall surface of the sieve 10, and eventually adhere to the sieve wall surface or Food waste caught in the sieve hole can be completely removed, and since food waste can be cut while being caught between the burr groove 39 and the burr 25, the food waste grinding efficiency can be increased.

As a preferred embodiment, an elastic leaf spring (not shown) is installed at one end of the inner and outer blades 20 and 22 (eg, at the opposite end of the end in contact with the wall of the strainer), respectively, and the leaf spring thus installed is installed inside and outside. By bringing the blades 20 and 22 closer to the wall surface of the sieve, the inner and outer blades 20 and 22 clean up the food waste in the inner and outer walls of the sieve 10 and the hole 24 of the sieve 24. It can be scraped off or pulled out.

Here, the burrs 25 formed in the sieve hole 24 of the sieve 10 may be formed so that some of the burrs 25 protrude to the inside of the wall surface and some to the outside of the wall surface when the burr hole 24 is formed in the sieve 10. have.

Accordingly, when the entire ring gear 16 including the ring gear drive shaft 17 rotates, the inner blade 20 scratches the inner wall surface of the strainer inside the strainer, and at the same time, the outer blade ( 22) scrapes the inner wall surface and the outer bottom surface of the strainer, so that food waste caught in the wall surface and bottom surface of the strainer 10 can be completely removed.

In addition, the food waste disposal device of the sink includes a manual operation unit 26 as a means to provide an operating force for operating the gear type crusher 11 and to block odors rising from the drain of the sink.

The manual control unit 26 serves as an operating means for operating the gear type grinding device 11 and a closing means for blocking a sink drain when the sink is not in use.

To this end, the manual control unit 26 includes a cover 28 capable of covering the top of the strainer 10 and a cap 31 capable of turning the gear type grinding device 11.

The cap 31 is formed in a disc shape and is installed on the top of the strainer 10 installed inside the drain of the sink, and the entire drain including the open portion of the strainer 10 is covered by the cover 28 installed in this way. can be sealed.

At this time, the cover 28 can be installed in a structure that is detachably fitted to the drain side or the strainer side by using an elastic clip (not shown) in the form of bending a leaf spring mounted around the edge.

At the center of the cover 28, a circular cover housing 27 forming a vertical penetration structure is formed in a form extending vertically inward, and a cap 31 may be installed inside the cover housing 27 at this time. there will be

In addition, at the lower end of the cover 28, cap support pins 33 are horizontally installed at two places on both sides, and as the cap support pins 33 installed in this way extend a certain length into the cover housing 27, It is possible to prevent the cap 31 supported by being placed on this place from falling downward.

The cap 31 is a cylindrical cap with a closed top and a hollow inside, and is positioned coaxially inside the cover housing 27 formed on the cover 28 to move up and down and rotate horizontally at the same time. is installed with

That is, the cap 31 is fitted to the upper open portion (circular hole) of the cover housing 27 and is supported by being placed on the cap support pin 33 installed in the cover housing 27 using the lower end. structure, the cap 31 installed in this way can be moved in the vertical direction and rotated in the horizontal direction at the same time.

Here, a flange-shaped wing portion 37 is formed around the lower end of the cap 31, and when the cap 31 is pulled upward, the wing portion 37 is formed on the lower surface around the upper open portion of the cover housing 27. As it can be caught on, it is possible to prevent the cap 31 from falling upward.

In addition, a plurality of cap holes 29 are formed along the circumference of the wall surface of the cap 31, and through the cap holes 29 formed in this way, water and food waste in the sink are drained and sent to the strainer 10. be able to

At this time, the cap hole 29 formed in the cap 31 is located below the cover 28 when the cap 31 is pressed and closed, that is, when the cap 31 is at the lower limit position, and accordingly the sink As the drain is completely blocked, it is possible to prevent odors from leaking out, and when the cap 31 is pulled up and opened, that is, when the cap 31 is in the upper limit position, it is located above the cover 28, and accordingly Water and food waste on the bottom of the sink can be discharged through the cap hole 29 .

In addition, a handle 36 is protruded from the upper end of the cap 31, and accordingly, when manipulating the cap, the user can hold the handle 36 with his hand and easily turn the cap 31.

In particular, the cap housing 30 in the form of a circular tube is vertically formed on the inner ceiling of the cap 31, and slots 35 are formed vertically and long from the lower end of the cap housing 30 on both sides of the outer circumferential surface of the cap housing 30. are formed respectively.

The cap 31 having the cap housing 30 and the slot 35 is supported by being placed on the cap support pin 33 of the cover housing 27 through the lower end while being located inside the cover housing 27. On the other hand, along with this, the cap 31 is inserted into the drive shaft connecting pin 34 of the ring gear drive shaft 17 from below through the slots 35 on both sides of the cap housing 30, and at the same time the cap housing 30 ) is combined with the ring gear drive shaft 17 in a structure for accommodating a part of the upper end of the ring gear drive shaft 17.

Accordingly, the cap 31 can be rotated together with the ring gear drive shaft 17 by the engaging structure between the drive shaft connecting pin 34 and the slot 35, and the drive shaft connecting pin 34 and By using a structure capable of sliding up and down between the slots 35, the ring gear drive shaft 17 can be moved up and down alone in a stationary state.

As a preferred embodiment, at the lower end of the cap 31, a plurality of inclined step grooves 32 disposed at regular intervals along the cap circumferential direction, that is, one side is a vertical surface and the other side is an inclined surface. A molded step groove 32 is formed.

Accordingly, the cap 31 is formed by using the bottom part of the inclined stepped groove 32 (the part where the vertical surface and the inclined surface meet) or the lower part of the cap 31 (the flat part between the inclined stepped grooves) The cover 28 is placed on and supported by the cap support pin 33 fastened to the cover housing 27 so that the raised position and the lowered position can be maintained.

For example, when the bottom portion of the inclined stepped groove 32 of the cap 31 is placed on the cap support pin 33, the cap 31 at this time can maintain the lower limit position, and the cap support pin ( 33), when the lower part of the cap 31 is put on, the cap 31 at this time can maintain its upper limit position.

Of course, since the engaging relationship between the slot 35 and the drive shaft connecting pin 34 is maintained even when the cap 31 is at the upper limit position, there is no problem in turning the cap 31 and the ring gear drive shaft 17 together. there will be no

In this way, the manual control unit 26 composed of a combination of the cover 28 and the cap 31 is installed on the top of the strainer 10, and at the same time, the cap 31 of the manual control unit 26 and the gear type grinding device 11 By binding the ring gear drive shafts 17 of each other, it is possible to easily operate the gear type crusher 11 using the manual control unit 26.

That is, a simple operation of turning the cap 31 operates the gear type pulverizer 11 to effectively pulverize food waste.

In addition, the gear type grinding device 11 is operated by using the manual control unit 26 covering the sink drain to prevent odors without using a separate operating means for operating the gear type grinding device 11. As a result, there are advantages in terms of structure, number of parts, and handling and use.

Therefore, the use state of the food waste disposal apparatus configured as described above is as follows.

Here, the strainer 10 may be installed in a structure accommodated in a known strainer housing (not shown) inside the sink drain, and a detailed description of the arrangement relationship between the strainer 10 and the strainer housing is omitted. do it with

In addition, a strainer fixing ring 38 is installed around the outer circumference of the upper end of the strainer 10. At this time, the strainer fixing ring 38 vertically incises a part of the upper end of the upper and lower width of the ring, and then moves the incised part outward. It is made in a slightly open shape, so that it can exhibit elasticity.

Accordingly, when the strainer fixing ring 38 is installed around the outer circumference of the upper end of the strainer 10, and the strainer 10 is inserted into the sink drain in this state, the gap between the strainer 10 and the sink drain is about 2 to 3 mm. Since the upper incision in the strainer fixing ring 38 elastically fills, the strainer 10 does not run idle even when the gear type grinding device 11 operates, and the strainer 10 is easily inserted into the sink drain. can be put in or taken out.

First, when the sink is not in use, the cap 31 of the manual control unit 26 is closed (see FIG. 5).

That is, the cap 31 is lowered so that the inclined stepped groove 32 in the cap housing 30 rests on the cap support pin 33.

In this case, since the drain of the sink is completely sealed, odors and the like can be prevented from leaking through the drain.

Next, when using the sink to do the dishes, etc., the cap 2 (31) of the manual control unit 26 is opened (see FIG. 6).

That is, the lower end of the cap housing 30 is placed on the cap support pin 33 by lifting the cap 31 upward.

In this case, since the cap hole 29 in the cap 31 is exposed, water and food waste can enter the strainer 10 through this hole.

Next, when food waste is collected to some extent in the strainer 10 after washing dishes, etc., it is possible to crush and remove the food waste in the strainer 10 using the food waste treatment device.

That is, when the user holds the handle 36 on the cap 31 of the gear type grinding device 11 and turns the cap 31, the ring gear driving shaft 17 and the ring gear 16 connected thereto When the ring gear 16 rotates, the planetary gear 16, the planetary gear carrier 15, and the sun gear 13 are rotated.

At this time, the planetary gear 15 engages with the sun gear 13 and rotates and revolves while rotating.

Here, when the cap 31 rotates, it rotates while repeatedly rising and falling slightly up and down due to the inclined stepped groove 32, but there is no problem in manipulating the cap 31.

Subsequently, the rotation of the planetary gear carrier 15 causes the guide blades 18 to rotate together, and at this time, the guide blades 18 scrape up the food waste collected at the bottom of the strainer 10 to remove the sun gear 13 ) and the planetary gear 14 are interlocked, and the food waste sent to the central area of the strainer is finely pulverized as it is pushed between the teeth of the sun gear 13 and the planetary gear 14 that mesh with each other. .

At the same time, the rotation of the ring gear 16 and the planetary gear carrier 15 causes the inner blade 20 and the outer blade 22 of the rotary blade 23 to rotate together, and the inner and outer blades 20, 22) removes food waste attached to the inner and outer walls of the strainer 10 or stuck in the hole 24 of the strainer 10 by scraping or taking it out.

Next, when the grinding operation of the food waste is completed to some extent, the cap 31 and the cover 28 are peeled off from the sink drain side or the sieve side, and then the sieve 10 is removed from the sink drain, and then the sieve 10 The food waste treatment is completed by shaking off the remaining food waste in the food waste container.

In addition, if water is sprayed on the gear type grinding device 11 and the strainer 10 to clean them, the food waste disposal device can be used again hygienically.

By processing the food waste in such a way that the food waste is finely pulverized using the gear type pulverizer 11, there is an advantage in that the amount of food waste generated can be remarkably reduced.

8 and 9 are perspective and cross-sectional views showing an apparatus for disposing of food waste in a sink according to another embodiment of the present invention.

As shown in FIG. 8 , here, a manual operation unit 26 installed in a drain hole of a sink to provide an operating force for pulverizing food waste and to prevent odor from rising through the drain hole is shown.

The manual control unit 26 has a cover housing 27 having a penetrating structure in the center and a cover 28 installed in an openable structure on top of the strainer 10, and a wall through which water and food waste can pass. It has a cap hole 29 and is installed in a structure capable of moving up and down and rotating in the cover housing 27 of the cover 28, and is connected to the crushing means side through the cap housing 30 formed on the inner ceiling and rotates together. It may be composed of a cap 31 to be.

The cap 31 of the manual control unit 26 rises while being supported by being placed on the cap support pin 33 fastened to the cover housing 27 of the cover 28 using the inclined stepped groove 32 formed at the lower end. Position and lowered position can be maintained.

In addition, the manual control unit 26 is connected to the ring gear drive shaft 17 of the gear type crusher 11 or the blade drive shaft 40 of the rotary blade 23, and when the manual control unit 26 is rotated Food waste can be pulverized by gear meshing action or blade cutting action.

Here, the coupling relationship between the manual control unit 26 and the gear type crusher 11 and the operation method interlocked together are the same as those of the above embodiment, so a detailed description thereof will be omitted.

Meanwhile, a coupling relationship between the manual control unit 26 and the rotary blade 23 and an operation method interlocking with each other are as follows.

As shown in FIG. 9, the rotary blade 23 is attached to the inner blade 20 for removing food waste attached to the inner wall surface of the strainer 10, the outer wall surface and the outer bottom surface of the strainer 10. It consists of an external blade 22 that removes food waste.

The inner blade 20 is a combination of a long strip-shaped square bar-shaped horizontal bar and a vertical bar, and is supported by welding on the blade drive shaft 40 using the horizontal bar, and the strainer 10 using the vertical bar. It is installed in a structure in close contact with the inner wall surface of the side by side and at the same time in close contact with the inner bottom surface of the strainer 10 using a horizontal bar.

These internal blades 20 can scrape the inner wall surface and the inner bottom surface of the strainer 10 while rotating together with the blade drive shaft 40, and eventually the inner blade 20 causes the inner wall surface or the inner surface of the strainer 10 to be scraped. Food waste attached to the bottom surface or stuck in the strainer hole 24 can be removed.

The outer blade 22 is formed by bending a long strip-shaped square bar into a "c" shape, and is supported by the blade drive shaft 40 and adheres to the outer wall surface and the outer bottom surface of the strainer 10. It is installed as, and can be rotated together with the blade drive shaft 40.

At this time, two driving shaft connection pins 34 are formed on the upper end of the blade drive shaft 40 supporting the inner blade 20 and the outer blade 22, respectively, and the drive shaft connection pin 34 formed in this way ) serves to connect the blade drive shaft 40 and the cap 31 to each other while being fitted into the slot 35 formed in the cap housing 30 of the cap 31 of the manual control unit 26.

In addition, the inner blade 20 and the outer blade 22 of the rotary blade 23 form a burr 25 formed in the sieve hole 24 of the sieve 10, for example, perforation of a punch when forming a sieve hole. As a result, food waste stuck in the sieve hole 24 sharply collides with each other while rotating while being in contact with the burr 25 protruding sharply in one direction and rotating to cut and remove the food waste. Internal and external blades ( 20, 22) can easily come out and be removed while being cut or crushed by the blade (end) and the sharp burr 25.

In particular, the inner blade 20 and the outer blade 22 are formed with a plurality of burr grooves 39 disposed at regular intervals in the up and down direction at the ends in contact with the wall surface of the strainer, and within the burr groove 39 thus formed. As the burr 25 in the sieve hole 24 of the sieve 10 is located, the blade parts of the inner and outer blades 20 and 22 can be in close contact with the wall surface of the sieve 10, and eventually adhere to the sieve wall surface or Food waste caught in the sieve hole can be completely removed, and since food waste can be cut while being caught between the burr groove 39 and the burr 25, the food waste grinding efficiency can be increased.

As a preferred embodiment, an elastic leaf spring (not shown) is installed at one end of the inner and outer blades 20 and 22 (eg, at the opposite end of the end in contact with the wall of the strainer), respectively, and the leaf spring thus installed is installed inside and outside. By bringing the blades 20 and 22 closer to the wall surface of the sieve, the inner and outer blades 20 and 22 clean up the food waste in the inner and outer walls of the sieve 10 and the hole 24 of the sieve 24. It can be scraped off or pulled out.

Here, the burrs 25 formed in the sieve hole 24 of the sieve 10 may be formed so that some of the burrs 25 protrude to the inside of the wall surface and some to the outside of the wall surface when the burr hole 24 is formed in the sieve 10. have.

Accordingly, when the manual control unit 26 is turned by hand, the blade drive shaft 40 rotates, and when the blade drive shaft 40 rotates in this way, the inner blade 20 moves inside the strainer on the inner wall surface of the strainer. At the same time, the outer blades 22 scrape the inner wall surface and the outer bottom surface of the strainer outside the strainer, so that food waste caught in the wall surface and bottom surface of the strainer 10 can be completely removed. .

As described above, in the present invention, the gear-type crushing device that crushes the food waste inside the sieve, the rotary blade that scrapes the food waste caught in the sieve, the role of sealing the sink drain, and the role of the operating means for operating the gear-type pulverizer By providing a new food waste disposal device including a manual control unit, etc., it is possible to reduce the amount of food waste, such as easily crushing and treating food waste generated in the sink, and reduce food waste disposal costs, Environmental pollution can be minimized by reducing the amount of food waste.
