Description

Door assembly for food garbage disposal device

The present invention relates to a door assembly for a food waste disposal apparatus, and more particularly, by opening and closing a link mechanism to a door assembly constituting a metering tube assembly and a vacuum shut-off device for the food waste disposal apparatus, opening and closing operation of the door interlocks with the link mechanism. The door assembly for food waste disposal devices that can improve airtightness and operability by adopting a method that can be made to ensure perfect sealing when the door is closed, as well as preventing noise when the door is opened and closed. It is about.

In general, food waste is mainly generated in the kitchen of each household, and is discharged in a state containing a large amount of moisture.

In this way, food waste generated in each household is disposed of in a fixed-rate bag in a separate amount from the general waste and collected in a designated place in front of the apartment, or placed in a separate food waste collection box and collected by the vehicle. Dispose of it in a way that allows it to be collected.

In the case of apartments such as apartments, this method of collecting food waste has the inconvenience of having to carry a heavy garbage bag containing food waste individually and throw it away at a designated place at a distance. In particular, food waste has a lot of moisture, so it cannot be left for a certain period of time. In the case of decay, odors are generated, and there are many environmental and sanitary problems such as unfavorable appearance due to the accumulation of food waste.

Such food wastes are usually disposed of together with general wastes in landfills or incinerators. In this case, there is a problem due to the content of moisture contained in the food wastes, and there is a problem of increasing environmental costs and worsening environmental pollution.

In order to solve this, food waste processors that can be used in each household are in widespread use, and after removing and stirring water, moisture is removed like normal waste and discarded completely.

For example, as a method of processing food waste by installing it in a sink in a home or restaurant, a fermentation method in which food waste is compressed and discharged using microorganisms, mechanically transported and dehydrated food waste, compressed and crushed There is a mechanical method for discharging later.

However, the food waste disposal method has a cost burden such as purchase and maintenance because each household must purchase and use a food waste disposal unit separately, and there is no facility to remove odors generated from food waste, and thus, moisture Even if it is removed, there is a risk of adversely affecting a pleasant living environment, such as difficulty in disposal like ordinary waste.

Accordingly, in recent years, a common food waste disposal system that can easily dispose of food waste in each household, does not harm the residential environment, and can be collected and disposed of together with general waste is being activated.

As an example, as disclosed in Korean Patent Registration No. 10-1481406, in multi-family apartments such as apartments, food waste inlets are installed in the sink for each household to extend the transfer pipe connected thereto to the basement, and the transfer The food waste discharged from the pipe is transferred to the processing unit in vacuum, and an integrated treatment system is operated through crushing and water removal.

The common food waste disposal system is equipped with a food waste disposal device capable of injecting food waste in each household, so that food waste can be conveniently disposed without going outside to dispose of the food waste.

On the other hand, in the case of apartments, villas, etc., where food waste is collected, the food waste collection bin is placed in a certain place so that food waste generated in each household can be freely disposed and a certain amount of money is collected for each household.

However, by adopting a method of collecting a certain amount of money for each household, since households infinitely throw away food waste, emissions are not reduced, but rather gradually increased, and awareness to reduce food waste is lowering. Even the amount collected by households is disproportionate and causes dissatisfaction.

Therefore, in recent years, after measuring the amount of food waste discharged by each household, a method of differently charging the treatment cost in proportion to the amount of discharge is adopted.

Thus, by accurately measuring the amount of food waste discharged by each household and differentially charging treatment costs, efficient management is possible and it is possible to induce households to reduce the amount of food waste discharged.

Accordingly, the applicant of the present application has developed a technology capable of increasing convenience and efficiency related to food waste disposal by combining a food waste disposal device and a food waste measurement method in accordance with the idea of the times, and has filed patent application No. 10-2018-0003564 It has been disclosed.

However, the door assembly configuration used in the existing food processing apparatus is that the shaft of the door plate and the shaft of the door motor are almost directly connected to rotate, so that the door plate is opened and closed by a fine gear gap inside the door motor. It was not possible to rule out the problem of slight flow during rotation.

That is, when the door plate is completely closed, this clearance causes the plate to flow, which does not provide a complete sealing force and causes food leakage. In addition, various problems have been exposed, such as the plate hitting the body and generating noise.

Korean Patent Registration No. 10-1481406 Korean Patent Registration No. 10-1317475

Therefore, the present invention has been devised in view of the above, and the link mechanism is grafted to the door assembly constituting the metering tube assembly and the vacuum blocking device of the food waste disposal apparatus so that the opening and closing operation of the door is performed in conjunction with the link mechanism. By adopting this method, it is possible to secure a perfect sealing force because the plate has strong adhesion and no flow when the door is completely closed or opened, as well as regulating the rotation angle when opening and closing the door to prevent the noise of plate collision. An object of the present invention is to provide a door assembly for a food waste disposal device capable of improving airtightness and operability.

As shown in the figure, the food waste disposal apparatus may contain a certain amount of food waste to measure food waste discharged from the sink side, and a weighing tube assembly serving to discharge the weighed food waste ( 15).

The metering tube assembly 15 is installed in a stacked structure in order from the top, and the food metering tube 10, the food metering box 11 and the food metering hopper 12 that are in communication with each other, as well as food before and after weighing It is made of a structure including a door assembly 14 and the like to confine or pour out.

The food metering pipe 10, the food metering box 11, and the food metering hopper 12 can be vertically arranged in a line while forming a coaxial structure, and can be used to trap food waste before weighing. It will be able to induce the falling route of post-food waste.

Looking at the coupling relationship between each of the components of the meter assembly (15), a known food discharge device 100 is installed on the outlet side of the sink, the hopper type outlet of the food discharge device 100 installed in this way ( The inside of the 110, the food metering pipe 10 is inserted, the portion of the lower straight pipe of the food metering pipe 10 at this time exits the hopper-type outlet 110 and extends vertically downwards, thereby measuring the food metering box 11 It is connected to the side by bolting structure.

Here, the food metering pipe 10 can be installed in a structure supported on the food metering box 11 while being able to slide up and down without interference while being accommodated inside the hopper-type outlet 110.

Accordingly, since there is no load supporting relationship with the hopper-type outlet 110 side when measuring the food metering pipe 10 containing food waste, in the case of the hopper-type outlet 110, the weighing value is not affected at all. do.

In addition, the food metering box 11 is made of a rectangular box shape, and the upper end of the food metering box 11 is coupled to the lower end of the food metering tube 10 in a fastening structure, and at the same time, the lower end is a load cell 18 to be described later. ) Can be installed in a structure supported on the side.

In addition, the food metering hopper 12 is a pipe that serves as a passage for discharging the metered food waste downward, and the upper end of the food metering hopper 12 is in a fastening structure with the lower end of the food metering box 11. At the same time, the lower end portion can be connected to the upper connection pipe 19 side of the vacuum blocking device 25.

The vacuum blocking device 25 is a means that can completely exclude the influence of the pressure (suction down force) by all the vacuum acting toward the lower tube when measuring food waste by the load cell 18, the metering tube assembly The same description as in (15) will be omitted.

Meanwhile, the door assembly 14 is disposed inside the food metering box 11 and rotates by the door motor 13 to serve to open and close the lower end of the food metering tube 10.

To this end, a plate-shaped door assembly 14 is disposed inside the food metering box 11, and the door assembly 14 can block the lower end of the food metering tube 10 while taking a horizontal posture. There will be.

Here, the door assembly 14, that is, the door plate 45 to be described later and the food metering pipe 10 so as to further improve the airtightness, the lower end of the food metering pipe 10 has an outer circumferential flange while having inner and outer flanges. Packing tube members 10a having the same diameter are combined.

One wall of the food metering box 11 has a cantilevered door shaft 35, which will be described later, installed through a rotatable structure.

Further, an axial bracket 36 is formed at one end of the door assembly 14, and a door shaft 35 is supported through the axial bracket 36 formed in this way. Here, the shaft bracket 36 is integrally formed with a pair of vertical members 36a and a top surface and an outer surface of the vertical members 36a formed at a predetermined interval so that the door shaft 35 can be stably supported and penetrated. It is formed of a bent plate member (36b) formed by bending, it is preferable to be bolted to the inner upper corner portion of the food metering box (11).

Accordingly, the door assembly 14 is able to open or close the lower end of the packing tube member 10a of the food metering tube 10 while being rotated about 90 ° in the vertical direction around the door shaft 35. .

For example, the door plate 45 of the door assembly 14 is in contact with the packing tube member 10a mounted on the lower end of the food metering tube 10 while taking a horizontal posture to open the food metering tube 10. It can be prevented, or can rotate about 90 ° and open the food metering tube 10 while taking a vertical posture.

In addition, the door motor 13 for opening / closing operation of the door assembly 14 is a motor capable of forward and reverse rotation, and is installed in a fastening structure outside the wall of the food metering box 11, and the door motor 13 installed in this way ) The shaft of the door assembly 14 is directly connected to the door shaft 35 or can be connected via a bushing member.

Accordingly, the door shaft 35 can be rotated by the operation of the door motor 13, and as a result, the entire door assembly 14 is rotated about the door shaft 35 as a central axis, and the food metering tube 10 ) Can be opened and closed.

In particular, the door assembly 14 is made in such a way that the door plate 45 is opened and closed by using the movement of the link mechanism such as the link shaft 42 and the link arm 43, thereby opening and closing the door plate. Since there is no flow at 45, the food metering tube 10 can be more closely and completely blocked and opened.

To this end, the door shaft 35, which is connected to the shaft of the door motor 13, is installed in the shaft bracket 36 coupled to the inside of the food container box 11, and is installed in such a way that the door shaft is installed. A pair of pins 40 forming a 90 ° right angle with respect to the axis are integrally formed in the middle portion and the tip portion of the 35, and the pins 40 at this time are pin holes 41 on the link arm 43 side to be described later. ) In a slidable structure.

And, while maintaining a certain distance from each other, a pair of link arms 43 are provided side by side, and at this time, the pair of link arms 43 are fixed across each link arm and fixed, and a pin hole block formed in a bar shape It is integrally coupled via (49), and the rear ends of the pair of link arms 43 that are integrally coupled are rotatably supported by the link shaft 42 on the shaft bracket 36. .

Accordingly, the pair of link arms 43 can be rotated up and down about 90 ° with the link shaft 42 at the rear end as the central axis.

Here, the position of the link shaft 42 that is fastened to the shaft bracket 36 may be positioned behind the door shaft 35 (relative to the vertical axis of the food metering tube).

In addition, the pin hole block 49 connecting the pair of link arms 43 penetrates along the block diameter direction and at the same time has a certain distance from each other (for example, an interval corresponding to the distance between both pins on the door axis). ), Two pin holes 41 are formed, and each pin hole 41 formed in the door shaft 35 can be fitted to each pin hole 41 formed in this way.

Accordingly, when the door shaft 35 is rotated, as shown in FIGS. 6A to 6C, the pin 40 of the door shaft 35 is also rotated together with the door shaft 35 as a central axis, thereby allowing the pin hole block 49 to be rotated. Since it is possible to rotate the entire link arm 43 to be lifted up or down, the link arm 43 can also be rotated while being interlocked with it when the door shaft 35 is rotated.

In this way, when the door shaft 35 and the link arm 43 are interlocked, the pin hole 41 and the pin 40 sandwiched therein can slide between each other.

At this time, the upper end of the rear end of the pair of link arms 43 has a concave arc-shaped door shaft seating groove 48 formed downward, and the door shaft is located in the door shaft seating groove 48 formed in this way. As the 35 is seated and caught, the upper limit rotation of the door plate 45 including the link arm 43 can be regulated.

For example, when the link arm 43 takes a horizontal posture (closed state) by the rotation of the door shaft 35, the door shaft in the door shaft seating groove 48 in the link arm 43 at this time As the seat 35 is seated, movement in the upward direction is limited, and in the end, the link arm 43 can no longer move upward at this position, so the door plate 45 coupled to the link arm 43 in this state ) Also, upward movement is regulated, so that the lower portion of the food metering tube 10 can be blocked while taking a horizontal position.

In addition, the door plate 45 is provided as a means for substantially opening and closing the lower end of the food metering tube 10, and the door plate 45 provided in this way is placed on the upper surface of the tip of the pair of link arms 43 and In addition, it is installed in a structure supported by the fastening structure of the link pin 46.

That is, on the bottom surface of the door plate 45, a door plate reinforcement plate 50 formed of two parallel bars on both sides is vertically formed, and a link pin between the door plate reinforcement plate 50 and the link arm 43 formed in this way Since the 46 is fastened, the door plate 45 can be installed in a structure supported on the link arm 43 side through the link pin 46.

The door plate 45 installed in this way is able to move upwards or downwards in a direction opposite to each other based on the seesaw movement, that is, the front of the plate and the back of the plate, based on the link pin 46 around the fastening portion of the link pin 46. There will be.

Particularly, one end is provided around the support portion of the door plate 45, that is, around the link pin 46, which is installed in a structure capable of seesaw movement through the link pin 46 on the pair of link arms 43. While being supported on the link arm 43 side, the torsion spring 47 supported on the bottom surface of the door plate 45 at the other end may be installed while the link pin 46 is wound several times. Here, as a means for supporting the torsion spring 47 on the link arm 43 side, a support pin 47a may be further formed to cross between the link arms 43.

Accordingly, the door plate 45 takes an inclined posture in the open state of the door plate 45 by the force pushed by the torsion spring 47, and the packing tube member 10a in the closed state of the door plate 45 ), It is relatively retracted by the force in contact with it, so it can take a horizontal position.

For example, in the open state of the door plate, the tip portion of the door plate 45 is lifted by the inflation force exerted by the torsion spring 47 to take an inclined posture, and the bottom surface of the tip portion of the door plate 45 is a link arm. It is in a state away from the inclined surface 51 formed on the upper surface of the distal end portion of (43).

And, when the door plate is completely closed, the upper surface of the door plate 45 is pressed to the lower end of the packing tube member 10a, and the torsion spring 47 is also compressed at this time, so the door plate 45 has an inclined surface ( While rotating in the direction of 51), the seesaw moves naturally and is in close contact with the lower end of the packing tube member 10a while taking a horizontal posture.

At this time, the door plate 45 is in close contact with the lower end of the packing tube member 10a in a posture in an inclined position, so that the front to the back is gradually pressed without any load and noise, and can be closely adhered, eventually packing It is possible to maintain a perfect tightness, that is, a perfect tightness, over the entire lower circumference of the tube member 10a.

As a more preferred embodiment of the door plate 45, as shown in FIGS. 5A and 5B, the food placed on the upper surface of the door plate 45 is not adsorbed on the flat plate surface and can be discharged more smoothly downward. The food sliding plate 44 to be formed may be integrally formed.

That is, on the upper surface of the door plate 45, as shown in FIG. 5A, a horizontally symmetrical inclined surface (an inclined surface of a structure descending from both sides at an apex in the middle of the door plate width) or a food sliding plate made of a convex upward surface as shown in FIG. 5B ( 44) may be formed. Here, when the upper surface of the door plate 45 is made of an inclined surface or a curved surface as described above, it will be natural that the corresponding surface of the packing tube member 10a contacting thereon also consists of an inclined surface or a curved surface.

Accordingly, when the door plate 45 is opened, the food on the upper surface of the door plate flows down more naturally without being adsorbed on the food sliding plate 44, and in the end, the food does not remain on the door plate 45. It is discharged down to the bottom to prevent food from jamming when closed, thereby preventing malfunction.

Therefore, the door assembly structure configured as described above can provide a perfect sealing force to the packing tube member through the seesaw movement and the contacting plate, and the rotation method is linked to the shaft and pin even when the gear clearance of the motor occurs. Due to the force transmission structure, there is no flow of the plate, so the intermittent force can be doubled.
