Description

Technical Field

[0001] The present invention relates to the technical field of automatic vending equipment, and in particular to an automatic vending machine. Background Art

[0002] As the pace of modern life accelerates, consumers are increasingly demanding convenient and efficient catering services. As a new type of vending equipment, vending machines have gradually entered people's daily lives, especially in the fields of fast food and beverages. However, existing vending machines still have many deficiencies in hot food supply and cannot meet consumers' demand for on-site hot food processing.

[0003] Currently, most vending machines on the market can only provide pre-packaged food, such as cold drinks, snacks, etc. Although these foods are convenient, they often lack freshness and taste, and cannot satisfy consumers' desire for hot meals. Especially during peak lunch and dinner hours, consumers want to get hot meals quickly, but most existing vending machines are only equipped with a single heating unit and can usually only process one meal at a time. They cannot handle the heating needs of multiple meals at the same time, resulting in slow food delivery and failure to meet high demand in a short period of time.

[0004] This single heating unit design not only reduces the utilization rate of the equipment, but also limits the range of choices for consumers. Consumers often have to wait for a long time when choosing food, which not only affects the shopping experience, but also reduces the operating efficiency of the vending machine.

[0005] In order to meet this market demand, a new type of vending machine is urgently needed that can meet the needs of hot meal preparation during peak meal times and improve meal delivery efficiency. Summary of the invention

[0006] The purpose of the present invention is to improve the hot meal delivery efficiency of a vending machine to meet the dining needs of consumers during peak meal times such as lunch and dinner.

DETAILED DESCRIPTION

[0024] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0025] like Figure 1 As shown, the present invention provides a vending machine, comprising: a storage bin 1, for storing a plurality of different types of food; a processing bin 2, arranged adjacent to the storage bin 1, with a supply passage provided therebetween, for delivering a specified type of food to the processing bin 2; a plurality of heating units are sequentially provided in the processing bin 2 along a height direction, with a food delivery unit provided between adjacent heating units; The food outlet of the heating unit is connected to the food inlet of the food outlet unit via a transfer unit for transporting food; the processing warehouse 2 is provided with a pushing unit at the warehouse wall corresponding to the heating unit and the food outlet unit for driving the food to move between the supply channel, the heating unit, the transfer unit and the food outlet unit.

[0026] Users can purchase meals from the vending machine according to their preferences, and the purchased meals can be introduced from the storage bin 1 through the supply channel to the processing bin 2 for heating by any other known means such as a robot, a spiral aisle, a spring aisle or a crawler aisle.

[0027] However, the existing vending machines with hot meal supply have limited heating efficiency, and often cannot meet the surging demand for hot meals during peak meal times such as lunch or dinner, so that consumers either spend a long time waiting in line or choose to cancel the order, which not only affects the efficiency of the enterprise, but also reduces the user experience of consumers. Therefore, in this embodiment of the present application, multiple heating units are arranged along the height direction of the processing warehouse 2 to establish the advantage of the number of heating stations, so that the surging demand for hot meals can be met by simultaneous heating of multiple heating stations in a shorter time.

[0028] Specifically, Figure 2 As shown, two heating units are arranged along the height direction of the processing warehouse 2 as an example. Each heating unit corresponds to a supply channel, and each two adjacent heating units share a meal delivery unit between the two; wherein the supply channel is across the front of the heating unit and is connected to the storage warehouse 1. Optionally, the supply channel is configured to horizontally transfer the food taken out of the storage warehouse 1 to the front of the heating unit by deploying common mechanisms including but not limited to crawlers or robotic arms, and then the food in front of the heating unit is pushed into the heating unit by a pushing unit for heating. Because there are two heating units in the entire processing warehouse 2 at this time, the two heating units can be started at the same time to achieve heating of at least two meals.

[0029] Among them, since the space of the processing warehouse 2 is limited, in order to maximize the use of the space of the processing warehouse 2 to deploy the most heating units, the heating units are arranged vertically along the height direction of the processing warehouse 2 in this application. However, this arrangement will cause the heated food to be unable to smoothly enter the meal delivery unit for delivery, so a transfer unit is also provided in the embodiment of the present application, which moves between the meal delivery port of the heating unit and the meal delivery port of the meal delivery unit. Specifically, the heated hot meal will enter the transfer unit under the continued push of the pushing unit, and the transfer unit will carry the hot meal and move it to the meal delivery port of the meal delivery unit. The pushing unit here will push the hot meal on the transfer unit until it is pushed to the meal pickup port 9 so that consumers can get it.

[0030] like Figure 2 As shown, the overall layout of the supply channel, heating unit, transfer unit and meal delivery unit in the processing warehouse 2 is in an inverted "C" shape, so that the space in the processing warehouse 2 can be maximized to place more heating units while also establishing a complete meal delivery path from meal pickup, heating, transfer to meal delivery. Therefore, compared with the existing vending machines with hot meal function, this embodiment of the present application can take advantage of the arrangement of two heating units to heat at least two meals at the same time in a short period of time to meet the dining needs of consumers during peak meal times. The company can sell more meals, and consumers do not need to spend a long time waiting, thereby achieving the goal of improving meal delivery efficiency and achieving a win-win situation for both the company and consumers.

[0031] like Figure 3 As shown, optionally, the heating unit includes a steam generator 3 and a retractable steam nozzle 4; the steam generator 3 is fixed to the upper surface of a mounting plate 5, and the mounting plate 5 is fixed to the inner wall of the processing chamber 2 through a mounting frame; the retractable steam nozzle 4 is located below the mounting plate 5 and is connected to the steam generator 3 through a pipeline; a bottom plate 6 is provided in the processing chamber 2 corresponding to the bottom of the retractable steam nozzle 4, and the bottom plate 6 extends from the supply channel to the transfer unit. Figure 4As shown, optionally, a plurality of the retractable steam nozzles 4 are arranged above the bottom plate 6 to form a plurality of independent heating stations, so that a plurality of dishes can be heated simultaneously in one heating unit, thereby further improving the heating efficiency and the efficiency of hot meal delivery.

[0032] By connecting an external water tank or a direct drinking water pipe to the water inlet of the steam generator 3 (not shown in the figure), the steam generator 3 is continuously supplied with water. The steam generator 3 heats the water entering the steam generator 3 into hot steam by means of electric heating for standby use. The specific structure and steam generation principle of the steam generator 3 are prior art, and reference can be made to the 6kw small steam generator 3 of Xindaneng, which will not be described in detail here.

[0033] Under the push of the pushing unit, the food to be heated will be moved to the bottom of the retractable steam nozzle 4. Most of the existing hot food packaging methods are mostly plastic, aluminum boxes or paper boxes, so the optional end of the retractable steam nozzle 4 is conical, which is convenient for piercing the food box below after extension, so that the end of the retractable steam nozzle 4 can be inserted into the food box. At this time, the valve of the steam generator 3 will open, so that the hot steam in the steam generator 3 can be sprayed into the food along the pipeline from the retractable steam nozzle 4 to complete the task of heating the food. Among them, the retractable steam nozzle 4 can realize the retractable function of the steam nozzle through an electric telescopic rod or a cam transmission structure, as long as it can drive the steam nozzle to move up and down.

[0034] Optionally, in this embodiment, the amount of steam sprayed per unit time or the steam heating time can be controlled by an electrically controlled valve of the steam generator 3 to achieve heating of meals with different heating requirements.

[0035] When the food is heated, the pushing unit will continue to push the hot food to slide along the bottom plate 6 into the transfer unit.

[0036] Optionally, the bottom plate 6 is provided with a downwardly extending cleaning pipe 7 at a position corresponding to the retractable steam spray head 4, and the bottom end of the cleaning pipe 7 is connected to the waste water tank through a pipeline. With this design, the retractable steam spray head 4 can be self-cleaned.

[0037] Specifically, because a vending machine sells multiple types of meals at the same time, the states and flavors of different types of meals are different. At the same heating station, if the retractable steam nozzle 4 is just pulled out of the meal box of flavor A and then inserted into the meal box of flavor B, this will not only cause the food in the meal box of flavor A to be transferred to the lid of the meal box of flavor B due to the plugging action of the retractable steam nozzle 4, resulting in an unsightly appearance of the meal; more importantly, it will cause different flavors to be mixed in the meal of flavor B, resulting in cross-flavors, which seriously affects the taste and flavor of the meal.

[0038] Therefore, at the bottom of each heating station, that is, below the bottom plate 6, there is a cleaning pipe 7 extending downward corresponding to the retractable steam nozzle 4. After the food is heated and removed, the retractable steam nozzle 4 can be plugged into the cleaning pipe 7. At this time, the control valve of the steam generator 3 is opened, and the horizontally ejected steam will be blocked by the wall of the cleaning pipe 7 and will rebound to the surface of the retractable steam nozzle 4, thereby realizing the self-cleaning of the retractable steam nozzle 4. During the cleaning process, the sprayed food residues and liquefied water are introduced into the waste water tank through the pipe at the bottom of the cleaning pipe 7 for storage (not shown in the figure), and will be cleaned together when the subsequent maintenance personnel replenish the storage warehouse 1.

[0039] like Figure 5-Figure 6 As shown, optionally, the meal dispensing unit includes a carrier 8 and a meal taking port 9; the meal taking port 9 is opened at the front end of the processing chamber 2, and the carrier 8 extends horizontally from the meal taking port 9 into the processing chamber 2 to the transfer unit. Optionally, the transfer unit includes a fixed plate 12, a first drive motor 10, a transmission assembly and a tray 20 assembly; the fixed plate 12 is fixed to the inner wall of the processing chamber 2, the first drive motor 10 is fixed to the fixed plate 12, and its output shaft is connected to the driving pulley 11; the transmission assembly includes a first driven pulley 13, a second driven pulley 14 and a third driven pulley 15 arranged coaxially; the driving pulley 11 is connected to the first driven pulley 13 by a transmission belt 16, and the second driven pulley 14 is connected to the third driven pulley 15 by a traction belt 17; a guide rail 18 is provided on the fixed plate 12 along the height direction, and a slider 19 is slidably connected to the guide rail 18, and the slider 19 is fixed to the traction belt 17; a plurality of trays 20 are evenly spaced on the side of the slider 19 close to the heating unit. Optionally, the pushing unit includes a truss 21, a second driving motor 22 and a push rod 23; a second driving motor 22 is provided at one end of the truss 21, and its output shaft is connected to a driving pulley 24; a fourth driven pulley 25 is provided at the other end of the truss 21, and the driving pulley 24 is connected to the fourth driven pulley 25 through a push-pull belt 26; a slide rail 27 is provided below the truss 21 along the length direction, and a push rod 23 is slidably connected to the slide rail 27, and the push rod 23 is fixed to the push-pull belt 26.

[0040] Specifically, when the heating unit heats the food, the second drive motor 22 is started, driving the drive pulley 24 to rotate synchronously, and the rotating drive pulley 24 drives the push-pull belt 26 to rotate in the truss 21 with the cooperation of the fourth driven pulley 25 at the other end of the truss 21; the rotating push-pull belt 26 pulls the push rod 23, so that the push rod 23 can move horizontally along the length direction of the slide rail 27, thereby using the horizontal part of the push rod 23 to push the heated food to the food outlet of the heating unit, and then the first drive motor 10 is started again to drive the active pulley 11 to rotate, and the rotating active pulley 11 synchronously drives the first driven pulley 13 and the second driven pulley 14 to rotate through the transmission belt 16; the second driven pulley 14 drives the traction belt 17 to rotate by cooperating with the third pulley; the rotating traction belt 17 pulls the entire slider 19 to slide vertically along the height direction of the guide rail 18, and then drives the tray 20 to slide vertically synchronously.

[0041] The first drive motor 10 pulls an empty tray 20 to be flush with the bottom plate 6 in the heating unit by forward or reverse rotation. At this time, the push rod 23 pushes the heated food in the heating unit along the bottom plate 6 to the tray 20 flush with the bottom plate 6 under the pull of the push-pull belt 26. Then the first drive motor 10 starts again to transport the heated food downward or upward until the tray 20 is flush with the carrying plate in the meal dispensing unit. At this time, the pushing unit located at the meal dispensing unit pushes the heated food from the tray 20 to the carrying plate, thereby completing the food transfer process from the heating unit to the meal dispensing unit.

[0042] The pushing unit can then continue to function to push the food on the carrying plate to the food taking port 9, making it convenient for consumers to take food.

[0043] Optionally, in addition to meeting the food transportation needs, the multiple trays 20 arranged in the array can also utilize the redundancy of the multiple trays 20 to transfer the heated food to the idle trays 20 for temporary storage, and then when the user arrives at the food pickup port 9, the temporarily stored hot food is transferred to the food delivery unit for delivery. In other words, the vending machine has the function of making reservations and ordering meals. Consumers can order meals in advance through online or offline platforms when it is close to meal time. The vending machine starts the heating program, and after heating, the meals are temporarily stored on the idle trays 20, waiting for consumers to pick up the meals, which further improves the convenience of using the vending machine.

[0044] Optionally, a touch screen 28 is installed on the outer side of the processing warehouse 2 near the food delivery unit pick-up port 9, and the user orders food according to the type, quantity and corresponding price information of the remaining food in the storage warehouse 1 displayed on the touch screen 28; the touch screen 28 sends the food information ordered by the user to the control system; the control system controls the supply channel, heating unit, transfer unit and food delivery unit according to the food information to heat the designated food and then deliver it.

[0045] Specifically, the design of the touch screen 28 can meet the needs of consumers for offline ordering. Consumers can send selected food signals to the control system by clicking on the touch screen 28. Of course, the electrical control components represented by the control system are also an indispensable part of the vending machine, for example, including but not limited to ultrasonic sensors that can feedback whether there is food on the tray 20, but it is not the invention of this application, so its structure and working method will not be described in detail here.

[0046] In summary, in the above embodiments, the present application arranges multiple heating units in a processing warehouse 2 with limited space through reasonable spatial layout and structural design, and connects multiple heating units and meal delivery units in series through a transfer unit, forming a movement path for food from meal pickup, heating, transfer and meal delivery, so that the vending machine of the present invention has efficient heating capacity. During peak meal times such as lunch or dinner, multiple meals are heated simultaneously through the simultaneous operation of multiple heating units, so as to heat and deliver more hot meals per unit time, and meet the dining needs of consumers during peak meal times. This not only improves the sales efficiency of the enterprise, but also saves the time for consumers to wait for meals, and improves the user experience.

[0047] It should be noted that the above is only an implementation method of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention. At the same time, the electrical components involved in the vending machine of the present invention, such as the drive motor, the touch screen 28, etc., are all common mature products in the prior art. The application of these electrical components in the present invention is mainly to realize the automatic control and operation of the vending machine and improve the operating efficiency and stability of the equipment. It is not the inventive point of the present invention. Its specific models and specifications can be selected and configured according to actual needs.
