In other words, the catering cart is movable and allows a plurality of containers to be mounted, thereby enabling a catering service even in a narrow space and has the advantage of being able to be used in various places.

Here, depending on the type of food, it must be eaten warm or cold to provide its original taste.

Most of all, in the summer, when food is easily spoiled, there is a problem that the taste is often spoiled during the transportation process, so that it is impossible to provide delicious and hygienic food to the patient.

Therefore, in order to solve this problem, a cooling and heating device was added to the distribution cart to keep food warm in winter and heat dissipation in summer.

However, since the cold and hot device is relatively expensive and consumes considerable energy, manufacturing and maintenance costs are increased.

In addition, the existing catering cart has a problem that man-hours are wasted in operating the catering cart because the food service personnel must directly drive and move to the food service area according to the food service time.

In addition, the existing distribution cart has a problem that food is easily damaged due to contamination of the space by the residual food because the food storage space and the residual storage space are composed of a single space.

The present invention relates to a distribution cart that contains food and moves to a hospital room to supply meals to a patient. As shown in FIG. 1, the main configuration includes a distribution apparatus 10, a cabinet 20, an electric cart 30, and a control module 40. It is an electric distribution cart for nursing homes based on autonomous driving.

First, the serving apparatus 10 according to the present invention is composed of a serving container 11 containing at least freshly cooked food as shown in FIG. 1 along with a spoon or a plate, and a leftover container 15 for collecting leftover food.

That is, the cutlery, plate, and serving container 11 are accommodated in the serving space 20a of the cabinet 20, and one or more leftover containers 15 are accommodated in the remaining space 20b of the cabinet 20.

Here, the distribution container 11 is composed of a storage container 11a, a container cover 11b, and an insulating material 11c as shown in FIG. 2.

The storage container 11a is made of a stainless steel material, and is formed in a box-like shape with a space for holding food of a set capacity.

The container cover 11b is made of stainless steel, and is detached/installed on the top of the storage container 11a to protect food.

The insulating material 11c is made of EPP or EPS foamed styrofoam, and is mounted so as to surround the outer surface of the storage container 11a to maintain the temperature of the food.

In other words, the existing serving vessel is composed of only a stainless steel vessel and a cover, so when waiting until the serving time, the food may be cold or spoiled.

On the other hand, the ration container 11 of the present invention can ensure safe hygiene as well as taste by maintaining the temperature of freshly cooked food as the insulating material 11c is mounted.

In addition, the cabinet 20 according to the present invention is a tower-type enclosure for storing the distribution device 10 as shown in FIG. 1, and a distribution space 20a and a residual space for storing at least the distribution container 11 and the residual container 15 separately. It is divided into (20b) and formed.

The cabinet 20 is composed of a storage box body 21, a shelf 22, a distribution door 23, a leftover drawer 24, and a handle 25 as shown in FIGS. 3 to 5.

The storage box 21 is a rectangular box made of iron and synthetic resin, and provides the distribution space 20a and the residual space 20b to be isolated vertically.

Here, the storage box 21 is equipped with a plurality of suction nozzles 21a on one upper surface that meshes with the edge of the residual drawer 24.

This suction nozzle (21a) is connected to the vacuum pump (37) and a hose to be described later serves to suck the air around the inlet of the residual container (15).

One or more shelves 22 are detachable/installed on the upper part of the storage box 21 to divide the distribution space 20a into multiple stages.

The distribution door 23 is hinged to be rotatable left and right on the upper portion of the storage box 21 to open and close the distribution space 20a.

The remnant drawer 24 accommodates the remnant container 15, and is mounted to be slidable back and forth in the lower part of the storage box 21 to enter and exit the remnant space 20b.

The handle 25 is mounted on the outer side of the distribution door 23 and the front drawer 24, respectively, to induce left and right opening and closing and front and rear entry and exit movements.

At this time, the cabinet 20 according to the present invention includes a switch 26, an electromagnet 27, a magnetic body 28, and a piezoelectric sensor 29.

The switch 26 is mounted to be exposed to a position selectively engaged with the distribution door 23 and the residual drawer 24 among the rims of the storage box 21.

The switch 26 serves to detect whether the distribution door 23 and the residual drawer 24 are opened or closed.

The electromagnet 27 is divided and built into a distribution space 20a and a residual space 20b among the rims of the storage box body 21.

This electromagnet 27 serves to lock with magnetic force so that only one of the distribution door 23 and the residual drawer 24 is opened according to a signal from the control module 40.

The magnetic body 28 is a metal embedded in the inner rim of the distribution door 23 and the residual drawer 24, and is magnetized according to the magnetic force generated from the electromagnet 27 to induce locking.

The piezoelectric sensor 29 is mounted to be concealed by a soft cover on the inner inner surface of the handle 25 to which the finger is in close contact.

The piezoelectric sensor 29 serves to detect the pulling of the distribution door 23 and the residual drawer 24 from the serving person.

In addition, the cabinet 20 according to the present invention may further configure an auxiliary space 20c that is isolated from the distribution space 20a and the remnant space 20b as shown in FIG. 6 at the rear.

That is, in the auxiliary space 20c, various tools necessary for distribution, furniture such as chairs and tables, and inspection documents may be stored.

Of course, in the auxiliary space (20c), as shown in FIG. 7, it is possible to configure a serving table T that is hingedly mounted from the storage box body 21.

Therefore, the serving person can quickly and easily open the distribution table (T) folded and stored in the cabinet 20 as shown in FIG. 8 to display the distribution tool 10.

Subsequently, the electric cart 30 according to the present invention is mounted under the cabinet 20 as shown in FIG. 1, senses the surrounding environment according to a signal from the control module 40, and autonomously moves to the distribution area.

Such an electric bogie 30 is a bogie frame 31, a driving wheel 32, an auxiliary wheel 33, a driving motor 34, a radar sensor 35, a purification unit 36, and a vacuum as shown in FIGS. 9 and 10. It consists of a pump (37).

The bogie frame 31 is a box-shaped skeleton having at least a size for loading the cabinet 20.

The driving wheel 32 is rotatably mounted at the center of the lower end of the bogie frame 31, and receives rotational force to induce driving and steering.

The auxiliary wheel 33 is rotatably mounted on the lower front and rear of the bogie frame 31, and distributes and supports the load of the cabinet 20.

The drive motor 34 is mounted inside the bogie frame 31 and is connected to the drive wheel 32 to add a rotational force according to a signal from the control module 40.

The radar sensor 35 is mounted on one side of the front and rear of the bogie frame 31, and senses the surrounding environment by transmitting and receiving electromagnetic waves.

The purification unit 36 is mounted inside the bogie frame 31 and circulates the internal air of the distribution space 20a to remove odors and dust.

The vacuum pump 37 is mounted inside the bogie frame 31, sucks air from the suction nozzle 21a and discharges it to the outside.

At this time, the purification unit 36 includes a purification box 36a, a blower fan 36b, an activated carbon filter 36c, and a HEPA filter 36d, as shown in FIG. 11.

The purification box 36a is fixedly mounted inside the bogie frame 31 and is connected to the cabinet 20 by a hose to provide an inlet and outlet through which air flows.

The blowing fan 36b is interposed at the inlet and outlet of the purification box 36a, and circulates the internal air of the distribution space 20a according to a signal from the control module 40.

The activated carbon filter 36c is built adjacent to the inlet of the purification box 36a, and filters odor particles contained in the air passing through.

The HEPA filter 36d is built adjacent to the outlet of the purification box 36a, and filters dust particles contained in the air passing through.

Therefore, as the internal air of the serving space 20a is continuously circulated without being stagnant, the rate of spoilage of food can be reduced by suppressing the growth of bacteria.

In addition, it is possible to maintain the taste and nutrition of freshly cooked food by maintaining it at a constant temperature regardless of the external temperature due to the circulation of internal air.

Finally, the control module 40 according to the present invention is mounted to be exposed on one surface of the cabinet 20 as shown in FIG. 1, and controls the cabinet 20 and the electric cart 30 according to a set sequence.

That is, the control module 40 autonomously moves the electric bogie 30 according to the previously input route and distribution time from the set waiting area to the distribution area.

For example, if a food service provider brings the food service tool 10 at 11 o'clock and puts it in the cabinet 20 and then sets the food service time at 12 o'clock, it takes into account the travel time to the designated food service area and reaches the minimum food service area at 11: 55 It departs automatically in time to arrive in minutes.

Therefore, even if the food service company or nursing home officials are not resident, the overall operation cost can be reduced by automatically moving to the food service area at the set time.

In addition, the control module 40 may learn the structure and driving environment of a nursing home in the process of moving from the waiting area to the feeding area, and thus can derive a departure time and a driving route suitable for the set feeding time.

In other words, even if the route from the waiting area to the food service area is input in advance, there is a possibility that the arrival time may be delayed due to environmental changes on the route or interference with oncoming patients or medical personnel.

Therefore, the control module 40 learns these obstacles and derives an optimum starting time and a driving route to induce smooth distribution.

At this time, the control module 40 receives a signal from the switch 26 in real time and determines whether the distribution space 20a and the remaining space 20b are opened or closed in real time.

In addition, the control module 40 determines whether the distribution door 23 is opened and the residual drawer 24 is pulled with a signal input from the piezoelectric sensor 29.

That is, when either of the distribution space (20a) and the residual space (20b) is in an open state, power is supplied to the electromagnet (27) to close any one of the distribution door (23) and the remnant drawer (24). Lock it to block simultaneous opening.

For example, when pulling the leftover drawer 24 while the distribution door 23 is open, power is immediately supplied to the electromagnet 27 to lock the leftover drawer 24 with magnetic force.

Likewise, when the front drawer 24 is pulled in the distributing door 23 in the advanced state, power is immediately supplied to the electromagnet 27 to lock the distributing door 23 by magnetic force.

Here, if the distribution door 23 and the balance drawer 24 are pulled at the same time without time difference, both the distribution door 23 and the front drawer 24 are locked.

Therefore, it is possible to prevent contamination of food stored in the distribution space 20a by blocking the simultaneous opening of the residual space 20b, which is relatively unclean, and the distribution space 20a requiring cleanliness.

In addition, since it prevents the inflow of the residual material into the distribution space 20a in the process of processing the residual material left after eating, it provides an advantage of easy maintenance.

Here, as the remnant container 15 is exposed to the outside due to the advance of the remnant drawer 24, an odor may be leaked during the remnant treatment process, resulting in a bad stomach or contaminating the ward.

That is, when the residual drawer 24 advances from the residual space 20b, the control module 40 operates the vacuum pump 37 in conjunction therewith.

When the vacuum pump 37 is operated, the plurality of suction nozzles 21a suck air around the inlet of the residual container 15, thereby preventing the outflow of odor.

Therefore, it is possible to treat the residuals in a pleasant environment, ensuring the satisfaction of not only patients but also food service personnel.

On the other hand, the electric distribution cart according to the present invention further includes a residual food processing unit 50 that is mounted in the residual food container 15 as shown in FIG. 12 to grind leftover food, juice the ground food, and separate and discharge it into ingredients and liquid. can do.

Here, the residual material container 15 is divided into a space in which the residual material processing unit 50 is mounted, and a material container 15a and a liquid container 15b for storing ingredients and liquids separated and discharged by the residual material processing unit 50, respectively. Is formed.

This residual processing unit 50 is composed of a grinder 51 mounted to be exposed to the upper end of the residual grinder 15 as shown in FIG. 13 and a juicer 52 mounted to be in communication with the lower portion of the grinder 51.

The crusher 51 includes a cylindrical case 51a that is detachable/mounted to the inner surface of the residual container 15, and a disc-shaped millstone plate 51b that is rotatably mounted by a motor in the center of the case 51a.

Here, helical-shaped grinding blades are formed on the inner surface of the case 51a and the outer surface of the millstone plate 51b.

The juicer 52 includes a filter tube 52a mounted at the bottom of the pulverizer 51, and a screw 52b rotatably mounted by a motor at the center of the filter tube 52a.

Here, the lower portion of the filter tube 52a is formed as a tray, so that the liquid of the ground food is immediately discharged to the lower portion, and the food mass remains at the top.

And the right end of the screw (52b) is connected to the filling cylinder (15b), the lower end of the filter cylinder (52a) is connected to the liquid cylinder (15b).

That is, when food is introduced while the millstone plate 51b is rotating, it passes between the inner surface of the case 51a and the outer surface of the millstone plate 51b, and is ground into a sludge form by the grinding blade.

The ground food is dropped into the filter tube 52a by its own weight, and the liquid of the dropped food is immediately discharged to the treatment container.

Further, the food lump remaining in the filter tube 52a is transferred to the right by the screw 52b, and the transferred food lump is blocked by a pressing plate and compressed.

The liquid phase is extracted due to the compression of the food mass, the extracted liquid phase passes through the tray by its own weight and is discharged into the liquid container, and the ingredients that reach the set pressure are discharged to the ingredients container as the pressing plate is opened.

In this way, while the food service is completed and the food service provider waits for collection, the collected residues are separated and discharged into ingredients and liquid, thereby reducing the number of man-hours required to collect the overall residue.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and is generally used in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications may be implemented by those skilled in the art, and these modified embodiments should not be individually understood from the technical spirit or perspective of the present invention.
