The wheels of the driving unit 10 may be covered by a housing as much as possible so as not to be exposed to the outside.

(14) A body unit 20 may be mounted at the top of the driving unit 10. At least a part of a lateral side of the body unit 20 may be open and an empty space may be formed inside the body unit 20 (e.g., a space 31 may be formed between a lower body part 21 and an upper body part 23 to be described below). Specifically, the body unit 20 may include a lower body part 21 mounted and fixed at the top of the driving unit 10, pillars 22 extending upward from the outer periphery of the lower body part 21, and an upper body part 23 connected to the lower body part 21 and supported by the pillars 22. The lower body part 21, the pillars 22, and the upper body part 23 may be assembled structures or may be integrally formed. The portion without the pillars 22 in the lateral side of the body unit 20 may be open. The upper body part 23 may have a flat top side 24, and a tray on which food containers may be placed may be disposed on the top side 24 as shown. The tray may be a common tray used in restaurants, or may be a special one having a shape or structure such that it may be more stably disposed on the upper body part 23.

(15) Through the open lateral side of the body unit 20, a body container 40 may be disposed in or taken out of the body unit 20. The body container 40 may have a shape similar to a basket, such that an empty space is formed therein; a lateral side thereof is closed; a top side thereof is open; and a bottom side thereof is closed. The shape of the body container 40 may be easily recognized with reference to FIG. 5.

(16) The body container 40 may be disposed in the body unit 20 in two states. In FIG. 3, the body container 40 is disposed in a first state. That is, the body container 40 may be disposed upside down such that the bottom (closed) side of the body container 40 faces upward to support food 41 or food containers 42. In FIG. 5, it is disposed in a second state. That is, the body container 40 may be disposed such that the top (open) side of the body container 40 faces upward to accommodate used food containers. The first state may be a state of the body container 40 when food is served, and the second state may be a state of the body container 40 when used food containers are collected.

(17) In FIG. 3, the component indicated by reference numeral 50 is an extension unit. The extension unit 50 may include removable pillars 51 that may be connected to the upper body part 23. This connection may be a removable connection. The extension unit 50 preferably includes a flat top side 54, and the tray may be placed on the top side 54 as shown in FIG. 3. Meanwhile, the extension unit 50 may also function to cover the upper parts of food containers disposed on the upper body part 23. Unlike the illustration, the extension unit 50 may be formed in several layers or may include a dedicated part for the placement of objects other than food containers. For example, the extension unit 50 may integrally or separately include a cylindrical housing having an open top side, which may accommodate forks, knives and the like.

(18) In the embodiment of FIG. 3, a tablet 60, which may be used by a customer or a user of the serving apparatus in inputting various commands, may be attached to the removable pillars 51 of the extension unit 50. The tablet 60 may communicate with the driving unit 10 in a wired or wireless manner. In the embodiment of FIG. 3, the location to which the tablet 60 is attached is only exemplary, and a part for the placement of the tablet 60 may be located anywhere in the serving apparatus and even outside the serving apparatus. Meanwhile, a smart phone, a personal computer, a POS (Point-Of-Sale) device and the like may be used instead of the tablet 60.

(19) Thus, according to the embodiment of FIG. 3, three serving spaces, i.e., a space above the closed side of the body container 40 in the body unit 20 (when the body container 40 is in the first state), a space above the top side 24 of the upper body part 23, and a space above the top side 54 of the extension unit 50 may be provided when food is served. Meanwhile, three spaces, i.e., the interior of the body container 40 in the body unit 20 (when the body container 40 is in the second state), the space above the top side 24 of the upper body part 23, and the space above the top side 54 of the extension unit 50 may be provided when used food containers are collected. Two spaces are provided when the extension unit 50 is removed. The number of provided spaces may increase when the extension unit 50 has several layers.

(20) FIG. 4 shows a situation in which a dedicated drink tray 30 is disposed on the body unit 20 of the serving apparatus according to one embodiment of the invention. In this embodiment, the configurations of the driving unit 10, the body unit 20, and the body container 40 disposed in the first state through the open lateral side of the body unit 20 are the same as in the embodiment of FIG. 3. The dedicated drink tray 30 may be configured such that a plurality of circular grooves are formed on its top side as seen from the top. Each of the circular grooves may be formed such that the lower part of a cup containing a drink is seated and easily fixed to some extent. The sizes of the circular grooves may be diverse. Meanwhile, a dish containing a hamburger, for example, may be disposed on the closed side of the body container 40. That is, it can be seen that a drink that spills more easily may be placed in the dedicated drink tray 30 and food that spills less easily may be placed on the closed side of the body container 40. The dedicated drink tray 30 may be disposed on the body unit 20 or elsewhere, for example, on the closed side of the body container 40 or on some extended components, depending on its use and configuration.

(21) Meanwhile, although the configuration in which the dedicated drink tray 30 includes a plurality of circular grooves has been described with reference to FIG. 4, various other configurations for holding cups (e.g., by using magnetic force between the cups and the dedicated drink tray 30 or fixing the cups with mechanical parts (such as clasps or rubber pads) rather than grooves) may be employed.

(22) FIG. 5 shows a state in which the body container 40 according to one embodiment of the invention is used for collecting food containers (i.e., the second state). The lateral side of the body container 40 may be formed tall enough so that used food containers and food remaining therein are not easily visible from the outside. Further, if the used food containers are accommodated in the body container 40 and then covered with a lid, cloth, paper towel, or the like, it is possible to prevent the discomfort experienced by other customers who have not used the food containers. Meanwhile, the tall side or the lid as above may prevent the falling of the remaining food to the floor of the restaurant. Meanwhile, the second state of the body container 40 may be used for carrying garbage depending on the type of restaurant.

(23) FIGS. 6 to 8 show examples of utilizing the above-described lid.

(24) FIG. 6 illustratively shows that a lid 70 covers the open top side of the body container 40.

(25) FIG. 7 illustratively shows that when the lid 70 has a flat top surface 74, a dish containing food is placed on the above surface 74 in a state in which the lid 70 is used for the body container 40.

(26) FIG. 8 illustratively shows that when the lid has a surface including a plurality of grooves for fixing a plurality of cups, the plurality of cups are placed on the above surface in a state in which the lid 70 is used for the body container 40.

(27) Thus, those skilled in the art will appreciate that the lid 70 of the body container 40 may be used, for example, in serving of food containers.

(28) FIG. 9 shows an exemplary serving process performed by the serving apparatus according to one embodiment of the invention.

(29) In step 1 of FIG. 9, an employee of a restaurant places food in each space of the serving apparatus, and then enters a table number using the tablet 60 of the serving apparatus. In step 2, the serving apparatus travels safely toward the table of the number entered in step 1. In step 3, a customer or employee moves the served food onto the table. When the above process is finished, the serving apparatus returns to a kitchen in step 4. The serving apparatus waits for the next task.

(30) The serving process as described above may be similarly applied when food containers are collected from the table where dining is finished. In this case, in step 1, an employee sets the serving apparatus to a collection mode, and enters the number of the table where dining is finished using the tablet 60 of the serving apparatus. Here, the setting to the collection mode may include disposing the body container 40 of the body unit 20 in the second state, placing a tray having a configuration suitable for collection on the upper body part 23 of the body unit 20, and the like. In step 2, the serving apparatus travels safely toward the table of the number entered in step 1. In step 3, the used food containers are accommodated in the body container 40 by an employee. The lid 70 may be used after the accommodation. However, the food containers in a relatively clean state may be disposed on the top side 24 of the upper body part 23 or the top side 54 of the extension unit 50, if necessary. When the above process is finished, the serving apparatus returns to the kitchen for dishwashing in step 4. The serving apparatus waits for the next task.

(31) In the above description of FIG. 9, the operation examples of the serving apparatus have been described with respect to the serving situation and the collection situation, respectively. However, the serving apparatus according to one embodiment of the invention does not necessarily operate according to the above examples. It should be understood that these examples do not limit the manner in which the serving apparatus operates.

(32) Further, all trays and food containers used in connection with the serving apparatus of the invention may be washed by a general dishwasher available in general consumer markets, a commercial dishwasher capable of rinsing, washing and sterilizing, or the like, and may preferably be manufactured such that they can be sanitized in compliance with restaurant hygiene regulations.

(33) Although the present invention has been described above in terms of specific items such as detailed elements as well as the limited embodiments and the drawings, they are only provided to help more general understanding of the invention, and the present invention is not limited to the above embodiments. It will be appreciated by those skilled in the art to which the present invention pertains that various modifications and changes may be made from the above description.

(34) Therefore, the spirit of the present invention shall not be limited to the above-described embodiments, and the entire scope of the appended claims and their equivalents will fall within the scope and spirit of the invention.
