Description

CRUSHER FOR GARBAGE DISPOSAL APPARATUS

TECHNICAL FIELD

The present invention relates to a crusher for garbage disposal apparatus, and more particularly, to a crusher for garbage disposal apparatus, which can easily dispose garbage by crushing and dehydrating the garbage dumped into an outlet of a sink.

BACKGROUND ART

In general, most of garbage discharged from houses or restaurants contains lots of moisture, and thereby pollutes soil and rivers.

For example, general garbage and dregs must be discharged in the state where the garbage is dried without moisture according to the Garbage Disposal Act. However, since there is a problem in that it takes a long time to separate garbage and dry it into the state where there is no moisture, people still put garbage containing moisture into a garbage bag and discharge it. Therefore, there occur several problems in that we get to face an environment where flies swarm or bacteria such as molds multiply around the garbage bag in the summer with a heat wave, and moisture or water flown out from the garbage permeates through rivers or subterranean water, and thus causes environmental pollution.

Therefore, recently, a dehydrating device for removing moisture of garbage has been on the market. Moreover, garbage disposal apparatuses, which resolve garbage using microorganisms, stir the garbage, remove moisture by a heater, and removes bad smell caused by harmful gas generated from prior mentioned process using a deodorizing device having a plasma member, an ion member and a filter member, has been disclosed and used.

Furthermore, a garbage disposal apparatus connected to a sink, particularly an outlet of the sink, for crushing and dehydrating garbage discharged from a house or a restaurant has been disclosed. Such garbage disposal apparatus is generally mounted on the lower portion of the sink for gathering and disposing the garbage through the steps of filtering, crushing and dehydrating the garbage which is induced into a sewage pipe.

For example, Korean Utility Model Registration No. 209783 discloses a garbage disposal apparatus. In Korean Utility Model Registration No. 209783, the garbage disposal apparatus includes: a hopper mounted on the upper portion of a frame; a motor mounted on the outside of the hopper and having an eccentric cam; a crusher mounted on the lower portion of the hopper and rotated by motive power; a tapered screw shaft mounted on the lower portion of the crusher, having a twist piece and rotated by the motive power; a reducer mounted at a side of the screw shaft and having a discharge hole and an outlet; a filter and a basin mounted on the outside of the discharge hole; and a zymogen medicinal fluid case connected to a compression part of the reducer and the screw shaft and a part of the hopper.

However, such apparatus has a problem in that the crusher is easily damaged due to adhesion of garbage onto the crusher and crushing efficiency deteriorate as time goes by.

In other words, since the conventional garbage disposal apparatus does not have the function to separate the garbage adhered on the crusher during the crushing process, a user has to wipe it off manually. Still, it is so hard to clearly remove the garbage adhered on the crusher that the garbage ends up being adhered on the crusher. Moreover, due to such problem, the garbage adhered on the crusher causes deterioration of work efficiency. DISCLOSURE OF INVENTION

Accordingly, the present invention has been made in view of the above pxoblems occurring in the prior art, and it is an object of the present invention to provide a crusher for garbage disposal apparatus connected to a sink, which includes scrapers having scraping plates for preventing adhesion of garbage onto crushing rolls when the garbage is crushed.

Another object of the present invention is to provide a crusher for garbage disposal apparatus, which has at least three alternate crushing blades in order to present the garbage from being adhered on the crusher or passed in a non-crushed state, thereby effectively crushing the garbage, and which provides the crushing blades with the inclination or the radius of curvature, thereby easily inducing and crushing the garbage.

To achieve the above object, in one aspect, the present invention provides a crusher for garbage disposal apparatus, which is installed on a sink used in a house or a restaurant for easily disposing garbage by crushing and dehydrating the garbage dumped into an outlet of the sink. The crusher comprises: main arrd slave crushing rolls mounted beneath a hopper in a line and having at least three crushing blades mounted on the respective outer circumferences thereof and interlocking alternately; and scrapers mounted on a housing and having scraping plates at regular intervals, the scraping plates fit between crushing blades of each crushing roll for scraping the garbage on the crushing roll when the crushing roll is rotated, in which the crushing rolls crush the garbage supplied from the hopper at different rotational speeds and when the crushing rolls are rotated, the scrapers mounted inside the housing scrape the garbage adhered on the crushing rolls.

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. FIG. 1 is a sectional view of a garbage disposal apparatus having a crusher according to the present invention, FIG. 2 is a sectional view, in part, of the garbage disposal apparatus having the crusher, FIG. 3 is an enlarged sectional view of the garbage disposal apparatus, FIG. 4 is a perspective view of the garbage disposal apparatus, and FIG. 5 is a partially enlarged view of the garbage disposal apparatus.

The garbage disposal apparatus 10 according to the present invention comprises a housing 100 having a hopper 101 communicating with an outlet 2 located at a side or the center of a sink bowl of a sink 1, a crushing part 200 for crushing garbage and dregs flowed into the hopper 101, a dehydrating part 300 for moving the garbage crushed by the crushing part 200 and for removing moisture of the garbage by compressing it, and an electrically operating part 400 for operating the crushing part 200 and the dehydrating part 300.

Here, the hopper 101 communicating with an inner installing space 102 is mounted on the upper portion of the housing, and connected to the outlet 2 of the sink 1. Inside the space 102, that is, the space located at the upper portion of the housing 100, a pair of crushing rolls 210 and 220 of the crusher rotating on a rotary shaft 201 connected to the electrically operating part 400 are mounted, and the dehydrating part 300 located beneath the crushing rolls 210 and 220 is also mounted.

Inside the lower portion of the space 102, moisture of the garbage is gathered in a gathering part 122 through a flow channel 120, and the flow channel 120 is communicated with a discharge pipe 130.

In other words, a front plate 110 is mounted on the front surface of the housing 100, and the discharge pipe 130 is assembled to the front portion of the front plate 110. A moisture outlet 112 communicating with the flow channel 120 is formed at the position where the discharge pipe 130 is assembled to the front plate 100, so that the moisture gathered in the discharge pipe 130 during dehydration flows into the flow channel 120 through the moisture outlet 112.

Meanwhile, the discharge pipe has a locking jaw 131 formed on an end portion thereof, and the locking jaw 131 is forcedly fitted to the front plate 110, and if necessary, it is fitted to the front plate 110 by packing or welding so as to prevent water leakage.

The dehydrating part 300 comprises a screw shaft 310 and a filtering member, namely filter 320, mounted inside the installing space 102 and the discharge pipe 130. The housing 100 further includes a garbage can 3 for gathering the dehydrated garbage.

The screw shaft 310 is injection-molded with metal or synthetic resin material, and has an inclined part 312 formed on the front part thereof and a spiral screw 311 formed on the outer circumference thereof. An end of the inclined part 312 of the screw shaft 310 protrudes to the outside, and the other end of the screw shaft 310 is fitted into a bearing 301, which is mounted on the housing 100, and then the screw shaft is connected to the electrically operating part 400. The pitch of the screw 311 is gradually narrowed toward the front portion, so that the garbage is compressed by the interval of pitch as the garbage is moved forward.

The electrically operating part 400 comprises a motor 410, a chain 430 and a sprocket 420 as electromotive means, namely a driving device. In the state where the sprocket 420 is mounted on the rotary shaft 201, the sprocket 420 and the chain 430 are mounted on a driving shaft 411 so as to transfer turning power of the motor. A pair of the sprockets are mounted on the driving shaft 411, wherein one of the sprockets is connected to a main rotary shaft 201 of the crushing part 200 and the other is connected to the screw shaft 310 of the dehydrating part 300 so as to transfer motive power to the crusher 200 and the screw shaft 310, respectively.

The crushing part 200 according to the present invention comprises the main and slave crushing rolls 210 and 220 rotating on the rotary shafts 201 and 201a, respectively and scrapers 230 and 240 for preventing adhesion of the garbage on the crushing rolls by scraping the respective crushing rolls. Power of the main crushing roll 210 is transferred to the slave crushing roll 220, so that the slave crushing roll 220 is sequentially operated together with the main crushing roll 210.

In other words, the rotary shaft 201 of the main crushing roll 210 is directly connected to the electrically operating part 400, and turning power of the rotary shaft 201 is transferred to the slave crushing roll 220 through driving means 250. The driving means 250 is actuated by interlocking of a main gear 251 mounted on the main rotary shaft 201 and a slave gear 252 mounted on the slave rotary shaft 201a. The gears 251 and 252 have teeth of different numbers from each other, so that the crushing rolls 210 and 220 are rotated at different turning speeds, respectively.

Each of the crushing rolls 210 and 220 has at least three crushing blades 211 and 221, preferably four crushing blades, and the crushing blades rotate alternately. The scrapers 230 and 240 have scraping plates 231 and 241 fitted to installing parts 212 and 222 disposed between the crushing blades for scraping and separating the garbage adhered on the respective crushing rolls. It is preferable that the installing parts 212 and 222 and the scraping plates 231 and 241 are precisely finished so as to closely fit the scraping plates 231 and 241 to the installing parts 212 and 222 disposed between the crushing blades 211 and 221.

The scrapers are assembled to right and left wall surfaces 103 of the installing space 102 of the housing 100, and at least four crushing blades 211 and 221 are bended at a predetermined inclination or with radius of curvature for preventing the garbage from being adhered on teeth roots 213 and 223. The scraper is made of one of generally used materials for scrapers, and preferably, stainless steel material.

For example, the crushing blades 211 and 221 apply the radius of curvature to the teeth roots 213 and 223 inclined at the predetermined inclination in the opposite direction to the rotational direction, so that the garbage drops down naturally when the teeth roots 213 and 223, on which the garbage is put, are rotated, thereby preventing adhesion, namely a tangle, of fibroid materials and easily drawing the garbage into the crusher and crushing it.

When the crushing blades 211 and 221 are rotated interlocking, the alternate crushing blades 211 and 221 inserted into the installing parts 212 and 222 tear the garbage, such as long fibroid material, to pieces so as to prevent the garbage from being adhered on the crushing blades. Furthermore, the teeth roots 213 and 223 have jaws 260, so that when a pair of crushing rolls are interlocked alternately, the crushing blade adjacent to each crushing roll scrapes the garbage adhered on an edge portion between the tooth root and the crushing roll.

It is preferable that the crushing blades 211 and 221 are formed integrally with the crushing rolls 210 and 220, but according to circumstances, it would be appreciated that semicircular type crushing blades may be assembled to the crushing rolls 210 and 220.

The crusher according to the present invention crushes the garbage flowed into the hopper 101 and supplies it to the dehydrating part 300. When the garbage is put into the hopper 101, the electrically operating part 400 is actuated. At this time, the electrically operating part 400 may be actuated by manipulation of a user or a sensor.

^"When the motor 410 is driven, the main rotary shaft 201 connected to the motor 410 via the chain 430 is rotated, and at the same time, the slave gear 252 interlocked with the main gear 251 is also rotated and the slave crushing roll 220 starts to rotate.

Of course, the main crushing roll 210 and the slave crushing roll 220 crush the garbage supplied from the hopper while rotating at different speeds due to the difference of the number of the teeth of the gears 251 and 252.

That is, the crushing blades 211 and 221 forcedly draw the garbage into the installing parts 212 and 222 and crush the garbage during the rotation, the garbage adhered on the installing parts 212 and 222 is separated from the installing parts 212 and 222 by the scraping plates 231 and 241 of the scrapers 230 and 240 assembled to the installing parts, and is crushed.

The crushed garbage drops down into the lower portion of the space 102, and the screw shaft 310 rotates to transfer the garbage. At this time, when the garbage is transferred forward, the garbage is compressed and dehydrated between the screw shaft 310 and the filter 320 by the screw 311 whose pitches are narrowed gradually, discharged to the outside, and then gathered into the garbage can 3. Meanwhile, moisture generated by the above process flows into the flow channel 120 through the moisture outlet 112 along the discharge pipe 130, and is gathered into the gathering part 122.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
