Description

Technical Field

[0001] This utility model relates to the field of boxed meal vending machine technology, specifically to a heating and compartment device for a boxed meal vending machine. Background Technology

[0002] Traditional meal vending machines or rice vending machines typically include a refrigeration zone and a heating zone. A conveyor system transports the preheated meals from the refrigeration zone to the heating zone for heating, and then the preheated meals are transported to the serving area. The heating zone can be equipped with an electric heating device or a microwave device to heat the meals.

[0003] Microwave heating is fast, but it is prone to localized overheating or uneven heating, which may destroy some nutrients and make food soft and sticky. It also places higher demands on food packaging, increasing product costs. Electric heating devices are slow and cannot meet consumer demand during peak hours. Increasing the space in the electric heating area to preheat more meals would meet peak demand within a certain period, but this would require transferring meals from the refrigerated area to the heating area after they are sold out, creating a waiting period. If this continues during peak hours or if peak hours coincide with the heating period, the same heating issues will arise. The problem remains unresolved, as customer flow issues cannot be effectively addressed. While replenishing a box as soon as it's sold ensures a continuous supply of preheated meals, this makes it impossible to control the heating time of each meal, resulting in meals past their optimal consumption period being sold, compromising freshness, leading to a poor customer experience, sales incidents, and lost customers. Furthermore, this timely replenishment method only allows for horizontal replenishment, meaning the heated meals are only heated on one row of surfaces closest to the conveyor. This limits the heating area to the row closest to the conveyor, failing to meet the practical need for on-demand heating and sales, and also results in a large space requirement for the equipment.

[0004] Therefore, the research objective of this utility model is to design a heating and compartmentalizing device for a boxed meal vending machine that can effectively achieve batch heating in separate compartments, greatly reduce the number of boxed meals recycled, effectively avoid gaps in supply to meet the consumption demand during peak hours, and achieve energy saving. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the present invention provides a heating and compartmenting device for a boxed meal vending machine, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A heating and dispensing device for a boxed meal vending machine includes:

[0008] The insulated box has its interior divided into multiple non-connected storage areas by corresponding partitions arranged side by side. The front of the insulated box is open and connected to a corresponding closed door.

[0009] The storage and unloading mechanism is installed in each of the storage areas. It includes a retractable loading component installed in the storage area and a screw driven by a motor to rotate above the loading component. When the motor rotates and drives the screw to rotate, the boxed meals placed in the corresponding spiral channel on the screw move forward one by one to be unloaded. When the loading component is inserted into the insulated box and in place, the motor is connected to the external power supply; otherwise, the connection is disconnected.

[0010] The heating system is used to heat the boxed meals in some storage areas in batches and at different times. When the number of boxed meals in the heated storage area is less than the limit value N, or when the heating time of the boxed meals in the heated storage area reaches the set value D1, the storage area to be heated will be heated. When the heating time of the boxed meals in the heated storage area reaches the set value D2, the heating and sale of the boxed meals in that storage area will be stopped, where D1 = D2 - D*n, D2 is the optimal consumption period of the heated boxed meals, D is the time taken to heat the boxed meals in the storage area to the limit temperature, and n is a non-zero natural number.

[0011] The rear side of the insulated box is provided with corresponding heat conduction holes for each storage area, and a corresponding heating mechanism is provided for each of them. The heating mechanism includes a ventilation fan and a heater fixedly installed on the outside of the heat conduction holes. The ventilation fan rotates to blow the heat from the heater into the storage area.

[0012] The rear side of the insulation box is connected to multiple heat-conducting pipes, each corresponding to a storage compartment. A corresponding exhaust pipe is located at the front. A limiting ring is fixed to the inner wall of the air inlet end of each heat-conducting pipe, and a closed ball is supported within the heat-conducting pipe by corresponding elastic elements. The closed ball abuts against the middle of the limiting ring, keeping the air inlet end of the heat-conducting pipe normally closed. The heating mechanism is installed on the rear side of the insulation box and driven left and right and up and down by corresponding drive components. After moving left and right to the heated storage compartment, the heating mechanism moves down to connect with the heat-conducting pipe. When the heating mechanism delivers hot air, the hot air blows downwards onto the closed ball, creating a gap between the closed ball and the limiting ring, allowing the hot air to enter the heated storage compartment through the gap.

[0013] The driving assembly includes a two-dimensional driving mechanism and a longitudinal driving mechanism. The two-dimensional driving mechanism includes a fixed guide rail horizontally arranged at the rear of the insulation box and extending to its left and right sides. A movable seat driven by a corresponding stepper motor is movably mounted on the fixed guide rail. The longitudinal driving mechanism includes a column fixedly connected upward to the movable seat. An electromagnet and a limiting seat are fixedly mounted on the column at vertical intervals. An iron mounting seat is movably mounted between the electromagnet and the limiting seat through a corresponding return spring. The heating mechanism is fixedly mounted on the iron mounting seat through a corresponding crossbeam. The heating mechanism includes a cylindrical component fixed to the end of the crossbeam. A ventilation fan and a heater are installed vertically inside the cylindrical component. When the heating mechanism is connected to the heat-conducting pipe, the cylindrical component is inserted into the heat-conducting pipe and abuts against the limiting ring.

[0014] The bottom of the object carrier is raised by a corresponding support component to set a distance between it and the bottom plate of the insulation box. When the object carrier is installed in place, it cooperates with the support component and the bottom plate of the insulation box to form a hot air conduction channel extending to the front and rear sides of the bottom of the object carrier. The object carrier has a number of ventilation holes evenly distributed on it, connecting the upper and lower parts of the hot air conduction channel. The support component includes a support plate fixed to the bottom surface of the object carrier. The support plates are connected end to end in sequence, and the front side of the object carrier protrudes from the front support plate and extends outward to form a corresponding handle. The rear support plate is provided with a through hole adapted to the heat conduction pipe. When the object carrier is installed in place, the air outlet end of the heat conduction pipe is inserted into the through hole.

[0015] An electrical connection assembly for electrically connecting the motor to an external power source is provided between the loading component and the corresponding storage area. The electrical connection assembly includes a plug installed at the end of the loading component and a socket installed on the inner side wall of the storage area. The plug is electrically connected to the electric controller of the motor and is fixedly installed outward at the end of the loading component through corresponding wires. When the loading component is plugged in and installed in place, the motor is electrically connected to the external power source through the plug and the socket; otherwise, the connection is disconnected.

[0016] The top of the closed door is rotatably connected to the insulation box via corresponding hinges. A power mechanism for driving the closed door to open and close is installed below both side walls of the insulation box. The power mechanism includes a connecting plate driven by a telescopic cylinder. The end of the connecting plate not connected to the telescopic cylinder is hinged with a corresponding arc-shaped arm. The closed door has a corresponding connecting piece at the position of the arc-shaped arm. The arc-shaped arm is detachably connected to the connecting piece by corresponding bolts. When the piston rod of the telescopic cylinder extends, it causes the closed door to flip upwards, opening the insulation box.

[0017] Advantages of this utility model:

[0018] 1) By adding the heating compartment device of this utility model to the boxed meal vending machine, the original boxed meal rack is improved and set up as an independent and heat-insulated box. The inside of the insulated box is divided into non-connected storage areas by a partition plate, and the boxed meals in each storage area are heated separately and asynchronously. This can effectively realize the batch heating of boxed meals in the vending machine, control the number of boxed meals heated at the same time, and greatly reduce the amount of boxed meals that have been heated beyond their optimal consumption period, thereby improving economic efficiency. Furthermore, this utility model adds a corresponding storage and unloading mechanism in the independently heated storage area. It includes a pull-out loading component installed in the storage area and a screw component driven by a corresponding motor to rotate above the loading component. This not only facilitates the individual removal of the loading component for changing goods, improving the convenience of changing goods and the practicality of the equipment, but also allows the heated boxed meals to be stored and heated longitudinally along the diameter and depth of the vending machine. This effectively solves the problem that the heating area can only be set in a row of planes near the conveyor device in the traditional way, further ensuring that batch heating can be realized.

[0019] 2) This utility model, through an improved heating mechanism, can independently heat each storage area asynchronously. When the number of boxed meals in the heated storage area is less than the limited value N, or when the heating time of the boxed meals in the heated storage area reaches the set value D1, the boxed meals in the storage area to be heated are heated in advance to ensure the continuity of supply. When the heating time of the boxed meals in the heated storage area reaches the set value D2, the heating and sale of the boxed meals in that storage area are stopped. By combining separate heating and time-limited sales, energy consumption can be saved while ensuring the quality of the boxed meals sold.

[0020] 3) This utility model provides corresponding conductive mechanisms at the rear of each storage area. These mechanisms include heat-conducting pipes connected to the rear of the storage area. The heat-conducting pipes are connected by a limiting ring and a vertically movable closing ball, forming a normally closed mechanism. A heating mechanism is also provided at the rear of the insulation box, moving horizontally and vertically. Simply move the heating mechanism to the storage area requiring heating and lower it so that the cylinder of the heating mechanism is inserted into the heat-conducting pipe and abuts against the limiting ring. The heat generated by the heater is then blown downwards by the air generated by the ventilation fan. As the hot air travels downwards, it pushes the closing ball... The downward blowing causes the gap between the closed ball and the limiting ring to open and connect the heat pipe. Then, the hot air enters the storage area to heat the boxed meals. This utility model can set corresponding heating mechanisms 5 on both sides of the insulated box 1. When the number of boxed meals in the heated storage area 101 is less than the limit value N, or when the heating time of the boxed meals in it reaches the set value D1, another heating mechanism 5 heats another storage area 101. The design of two heating mechanisms 5 working together can meet the heating needs of multiple storage areas on one insulated box at different times, reducing the investment cost of heating equipment.

[0021] 4) This utility model effectively solves the problem of requiring separate heating mechanisms for each storage area by adding a driving component to move the heating mechanism left and right and up and down, and greatly saves equipment costs. By using a stepper motor to control the moving seat on the fixed guide rail on the rear side of the insulation box and extending to its left and right sides, the heating mechanism can be accurately connected with each conducting mechanism. The heating mechanism is moved upward by the electromagnet when energized to make room for left and right movement. After the movement is in place, the electromagnet is de-energized, and the iron mounting base moves the heating mechanism downward under the action of gravity to connect with the conducting mechanism for hot air delivery. The corresponding return spring between the electromagnet and the iron mounting base can play a good buffering and protection role for the up and down movement of the iron mounting base, so as to ensure the practical effect of this utility model.

[0022] 5) The storage area of ​​this utility model features a pull-out support plate. Pulling the support plate outwards facilitates the loading of boxed meals by staff. A support component is added to the support plate, consisting of support plates connected end-to-end and fixed to the support plate. This support component reduces the contact area between the support plate and the bottom of the insulated box, thereby reducing the friction force during the pulling of the support plate. Furthermore, the support component, in conjunction with the bottom plate of the insulated box, forms a heat conduction channel extending to the front and rear sides of the bottom of the support component. The surface of the support plate is evenly distributed with numerous ventilation holes connecting the upper and lower parts of the heat conduction channel, facilitating the even distribution of heat to heat the boxed meals and improving the uniformity and consistency of heating. Additionally, the front side of the support plate protrudes outwards to form a handle, facilitating the pulling of the support component by staff.

[0023] 6) The rear side of the carrying plate of this utility model is provided with a corresponding electrical connection assembly, which includes a plug installed at the end of the carrying component and a socket installed on the inner side wall of the storage area. The plug is electrically connected to the electric controller of the motor and is fixedly installed at the end of the carrying component through corresponding wires. When the carrying component is plugged in and installed in place, the motor is electrically connected to the external power supply through the plug and socket; otherwise, the connection is disconnected. The motor and the external power supply can be adjusted by the intervention of the electrical connection assembly. When loading, the plug and socket with detachable electrical connection can be quickly separated to disconnect the motor from the external power supply, making it easy to pull out the carrying component for loading materials. After loading is completed, the carrying component is pushed into place, and the plug and socket are plugged in to connect the motor to the external power supply. While ensuring the ease of loading, this effectively solves the problems of wire entanglement and excessively long wire installation during loading, and can also disconnect the power supply when the carrying component is pulled out to ensure safe use, further ensuring the practical effect of this utility model.

[0031] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0032] Example 1

[0033] refer to Figure 1-3 A heating and dispensing device for a boxed meal vending machine, comprising:

[0034] The insulated box 1 is made of heat insulation board sealed and connected. Its interior is divided into multiple non-connected storage areas 101 by corresponding partition boards 2 arranged side by side. The front of the insulated box 1 is open and connected to a corresponding closed door 3.

[0035] The storage and unloading mechanism 4 is installed in each of the storage areas 101. It includes a retractable loading component 401 installed in the storage area 101 and a spiral component 403 driven by a motor 402 to rotate above the loading component 401. When the motor 402 rotates and drives the spiral component 403 to rotate, the boxed meals placed in the corresponding spiral channel on the spiral component 403 move forward one by one to be unloaded. When the loading component 401 is inserted into the insulated box 1 and is in place, the motor 402 is connected to the external power supply; otherwise, the connection is disconnected.

[0036] Heating unit 5 is used to heat the boxed meals in some storage areas 101 in batches and time periods. When the number of boxed meals in the heated storage area 101 is less than the limit value N, or when the heating time of the boxed meals in the heated storage area 101 reaches the set value D1, the storage area 101 to be heated is heated; when the heating time of the boxed meals in the heated storage area 101 reaches the set value D2, the heating and sale of the boxed meals in that storage area 101 is stopped, where D1 = D2 - D*n, D2 is the optimal consumption period of the heated boxed meals, D is the time taken to heat the boxed meals in the storage area 101 to the limit temperature, and n is a non-zero natural number that is set according to the site and sales situation. The set value N can be set according to the site and sales situation.

[0037] By adding a heating compartment device to the meal vending machine, the original meal rack is improved and converted into an independent, heat-insulated box 1. The box 1 is divided into non-connected storage areas by partitions, and the meals in each storage area are heated individually and asynchronously. This effectively achieves batch heating of the meals in the vending machine, controlling the number of meals heated at the same time, greatly reducing the amount of meals that have been heated past their optimal consumption period and thus improving economic efficiency. Furthermore, this invention further... A corresponding storage and unloading mechanism 4 is added, which includes a pull-out loading component 401 installed in the storage area 101 and a screw component 403 driven to rotate above the loading component 401 by a corresponding motor 402. This not only facilitates the individual removal of the loading component 401 for changing goods, improving the convenience of changing goods and the practicality of the equipment, but also allows heated boxed meals to be stored and heated longitudinally along the diameter of the vending machine, effectively solving the problem that the traditional heating area can only be set in a row of planes near the conveying device, further ensuring that batch heating can be realized.

[0038] This utility model, through an improved heating mechanism 5, can independently and asynchronously heat each storage area 101. When the number of boxed meals in the heated storage area 101 is less than a limited value N, or when the heating time of the boxed meals in the heated storage area 101 reaches a set value D1, the boxed meals in the storage area 101 to be heated are heated in advance to ensure the continuity of supply. When the heating time of the boxed meals in the heated storage area 101 reaches a set value D2, the heating and sale of the boxed meals in that storage area 101 are stopped. By combining separate heating and time-limited sales, energy consumption is saved while ensuring the quality of the sold boxed meals.

[0039] The rear side of the insulated box 1 is provided with corresponding heat conduction holes for each storage area 101, and a corresponding heating mechanism 5 is provided for each of them. The heating mechanism 5 includes a ventilation fan 501 and a heater 502 fixedly installed on the outside of the heat conduction holes. The ventilation fan 501 rotates to blow the heat from the heater 502 into the storage area 101.

[0040] An electrical connection assembly 13 for electrically connecting the motor 402 to an external power source is provided between the carrying component 401 and the corresponding storage area 101. The electrical connection assembly 13 includes a plug 1301 installed at the end of the carrying component 401 and a socket 1302 installed on the inner wall of the storage area 101. The plug 1301 is electrically connected to the electric controller of the motor 402 and is fixedly installed outward at the end of the carrying component 401 through corresponding wires. When the carrying component 401 is plugged in and installed in place, the motor 402 is electrically connected to the external power source through the plug 1301 and the socket 1302; otherwise, the connection is disconnected.

[0041] The rear side of the carrying plate of this utility model is provided with a corresponding electrical connection assembly 13, which includes a plug 1301 installed at the end of the carrying component 401 and a socket 1302 installed on the inner side wall of the storage area 101. The plug 1301 is electrically connected to the electric controller of the motor 402 and is fixedly installed outward at the end of the carrying component 401 through a corresponding wire. When the carrying component 401 is plugged in and installed in place, the motor 402 is electrically connected to the external power source through the plug 1301 and the socket 1302, and the connection is disconnected otherwise. The electric connection component 13 allows for adjustable connection between the motor 402 and the external power supply. During loading, the detachable plug 1301 and socket 1302 quickly separate, disconnecting the motor 402 from the external power supply, facilitating the easy removal of the loading component 401 for material loading. After loading, the loading component 401 is pushed into place, and the plug 1301 and socket 1302 are then connected to electrically connect the motor 402 to the external power supply. This effectively solves the problems of wire tangling and excessively long wire installation during loading, while ensuring ease of loading. Furthermore, the power supply can be cut off when the loading component 401 is removed to ensure safety, further enhancing the practical effect of this invention.

[0042] The top of the closed door 3 is rotatably connected to the insulation box 1 via corresponding hinges. A power mechanism 14 for driving the closed door 3 to open and close is installed below both side walls of the insulation box 1. The power mechanism 14 includes a connecting plate 1402 driven by a telescopic cylinder 1401. A corresponding arc-shaped arm 1403 is hinged to the end of the connecting plate 1402 not connected to the telescopic cylinder 1401. A corresponding connecting piece 15 is provided on the closed door 3 corresponding to the position of the arc-shaped arm 1403. The arc-shaped arm 1403 is detachably connected to the connecting piece 15 by corresponding bolt locking. When the piston rod of the telescopic cylinder 1401 extends, it causes the closed door 3 to flip upwards, opening the insulation box 1.

[0043] Example 2

[0044] refer to Figure 4-6 The difference between this embodiment and Embodiment 1 is that:

[0045] The rear side of the insulation box 1 is connected to multiple heat-conducting pipes 6, each corresponding to a storage area 101, and a corresponding discharge pipe 16 is provided on the front side. The inner wall of the air inlet end of the heat-conducting pipe 6 is fixed with a limiting ring 7 and a closed ball 9 supported by a corresponding elastic element 8. The closed ball 9 abuts against the middle of the limiting ring 7, so that the air inlet end of the heat-conducting pipe 6 is normally closed. The heating mechanism 5 is installed on the rear side of the insulation box 1 by a corresponding driving component 10 driving it to move left and right and up and down. After the heating mechanism 5 moves left and right to the heated storage area 101, it moves down and connects with the heat-conducting pipe 6. When the heating mechanism 5 delivers hot air, the hot air blows the closed ball 9 downwards, so that the closed ball 9 is spaced apart from the limiting ring 7, and the hot air enters the heated storage area 101 through the gap.

[0046] This invention features a corresponding conductive mechanism installed on the rear side of each storage area 101. This mechanism includes a heat-conducting pipe 6 connected to the rear side of the storage area 101. The heat-conducting pipe 6 is closed by a limiting ring 7 and a vertically movable closing ball 9. A heating mechanism 5 is also installed on the rear side of the insulation box 1, moving horizontally and vertically. By moving the heating mechanism 5 to the storage area 101 requiring heating and lowering it so that the cylinder 503 of the heating mechanism 5 is inserted into the heat-conducting pipe 6 and abuts against the limiting ring 7, the heat generated by the heater 502 is blown downwards by the gas generated by the ventilation fan 501. When the air is driven downwards, it blows the closed ball 9 downwards, so that the distance between the closed ball 9 and the limiting ring 7 is set to open and connect the heat conduction pipe 6. Then, the hot air enters the storage area 101 to heat the boxed meals. This utility model can set corresponding heating mechanisms 5 on both sides of the heat preservation box 1. When the number of boxed meals in the heated storage area 101 is less than the limit value N, or when the heating time of the boxed meals in it reaches the set value D1, another heating mechanism 5 heats another storage area 101. The design of two heating mechanisms 5 working together can meet the heating needs of multiple storage areas on one heat preservation box at different times, reducing the investment cost of heating equipment.

[0047] The driving assembly 10 includes a fixed guide rail 1001 horizontally disposed at the rear side of the insulation box 1 and extending to its left and right sides. A movable seat 1003 driven by a corresponding stepper motor 1002 is movably mounted on the fixed guide rail 1001. A corresponding column 1004 is fixedly connected upward to the movable seat 1003. An electromagnet 1005 and a limiting seat are fixedly mounted on the column 1004 at vertical intervals, and a phase-connected connection is established between the electromagnet 1005 and the limiting seat 1007. The corresponding return spring 1009 is movably mounted on an iron mounting base 1006. The heating mechanism 5 is fixedly mounted on the iron mounting base 1006 via a corresponding crossbeam 1008. The heating mechanism 5 includes a cylindrical member 503 fixed to the end of the crossbeam 1008. A corresponding ventilation fan 501 and a heater 502 are installed vertically inside the cylindrical member 503. When the heating mechanism 5 is connected to the heat-conducting pipe 6, the cylindrical member 503 is inserted into the heat-conducting pipe 6 and abuts against the limiting ring 7.

[0048] Furthermore, by adding a drive component 10 to move the heating mechanism 5 left and right and up and down, the problem of each storage area 101 requiring a separate heating mechanism 5 is effectively solved, and equipment costs are greatly reduced. By using a stepper motor 1002 to control the moving seat 1003 on the fixed guide rail 1001 on the rear side of the insulation box 1 and extending to its left and right sides, the heating mechanism 5 can be accurately connected with each conductive mechanism. The electromagnet 1005 is energized to drive the heating mechanism 5 mounted on the iron mounting base 1006 to move upward to make room for left and right movement. After moving into position, the electromagnet 1005 is de-energized, and the iron mounting base 1006 moves the heating mechanism 5 downward under the action of gravity to connect with the conductive mechanism for hot air delivery. A corresponding return spring 1009 is set between the electromagnet 1005 and the iron mounting base 1006 to provide good buffer protection for the up and down movement of the iron mounting base 1006, so as to ensure the practical effect of this utility model.

[0049] The bottom of the carrying component 401 is raised by a corresponding support component 11 to a distance from the bottom plate of the insulation box 1. When the carrying component 401 is installed in place, it cooperates with the support component and the bottom plate of the insulation box 1 to form a hot air conduction channel 12 extending to the front and rear sides of the bottom of the carrying component 401. The carrying component 401 has a plurality of ventilation holes evenly distributed on it, connecting the top and bottom of the hot air conduction channel 12. The support component includes a support plate fixed to the bottom surface of the carrying component 401 around the perimeter. The support plates are connected end to end in sequence, and the front side of the carrying component 401 protrudes from the front support plate and extends outward to form a corresponding handhold. The rear support plate is provided with a through hole adapted to the heat conduction pipe 6. When the carrying component 401 is installed in place, the air outlet end of the heat conduction pipe 6 is inserted into the through hole.

[0050] The storage area 101 of this utility model features a pull-out support plate. Pulling the support plate outwards facilitates the loading of boxed meals by staff. A support component 11 is added to the support plate, consisting of support plates connected end-to-end and fixed to the support plate. The support component 11 reduces the contact area between the support plate and the bottom surface of the insulated box 1, thereby reducing the friction force during the pulling of the support plate. Furthermore, the support component 11, in conjunction with the bottom plate of the insulated box 1, forms a hot air channel 12 extending to the front and rear sides of the bottom of the support component 401. The surface of the support plate is evenly distributed with numerous ventilation holes connecting the upper and lower parts of the hot air channel 12, facilitating the even distribution of hot air to heat the boxed meals and improving the uniformity and consistency of heating. Additionally, the front of the support component 401 protrudes from the front support plate and extends outwards to form a handle, facilitating the pulling of the support component 401 by staff.

[0051] It should be noted that this embodiment is implemented in the same way as the first embodiment in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
