Description

Technical Field

[0001] This invention belongs to the field of food serving machine technology, and specifically relates to a quantitative food serving device. Background Technology

[0002] With the development of intelligent technology, kitchen equipment is becoming increasingly intelligent and automated. However, schools, military units, corporate canteens, and large restaurant chains still use manual portioning for serving food, which requires a lot of manpower and time and is not very efficient.

[0003] Patent application number CN202211326013.9 discloses an automatic quantitative food dispensing machine, relating to the field of food dispensing machines. This automatic quantitative food dispensing machine includes a food storage component, a food dispensing container, and a quantitative dispensing component. The food storage component has a food storage cavity, and the food dispensing container has a food dispensing cavity and a food inlet and a food outlet communicating with the food dispensing cavity. The food inlet is connected to the lower part of the food storage cavity, and the food outlet is located below the food inlet. The quantitative dispensing component includes a first quantitative dispensing piece, a second quantitative dispensing piece, and a quantitative dispensing drive. The first and second quantitative dispensing pieces are spaced apart vertically and both are connected to the food dispensing container. The quantitative dispensing drive is drively connected to the first and second quantitative dispensing pieces, used to cause either the first or second quantitative dispensing piece to block the food dispensing cavity. This invention can achieve automatic quantitative food dispensing, which helps reduce labor input and improve food dispensing efficiency.

[0004] However, the aforementioned food serving machine can only serve one type of dish in fixed quantities, and cannot serve multiple dishes in fixed quantities and automatically plate them. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this invention is to provide a quantitative food serving device that can simultaneously quantitatively divide multiple dishes and automatically plate them.

[0006] The technical solution adopted in this invention is as follows: A quantitative meal distribution device includes a body, an upper part of which is provided with a meal distribution storage unit, a meal distribution dropping unit fixed inside the body, and a meal distribution quantitative unit installed inside the body for controlling the opening and closing of the channel between the meal distribution storage unit and the meal distribution dropping unit. A lifting drive unit is installed at the lower part of the body, and the output end of the lifting drive unit is aligned with the lower opening of the meal distribution dropping unit. Both the meal distribution storage unit and the meal distribution dropping unit have several compartments, and the meal distribution quantitative unit has several quantitative holes. The several compartments of the meal distribution storage unit, the several quantitative holes of the meal distribution quantitative unit, and the several compartments of the meal distribution dropping unit correspond one-to-one.

[0007] Initially, the food portioning unit rotates until it connects with the food storage unit. Food automatically falls into the portioning unit, and when it fills the container, it is temporarily stored in fixed quantities. When serving, a bowl is placed on the output of the lifting drive unit, which raises the bowl. The portioning unit then rotates until it connects with the food dropping unit, and the food falls from the dropping unit into the bowl, achieving automatic plating. During the food dropping process, the food storage unit and the portioning unit are not connected. The portioning unit then returns to its initial state.

[0008] The container of the portion control unit serves as a temporary storage container for the dishes. By setting the volume of the portion control unit, the amount of each dish can be controlled.

[0009] Furthermore, the quantitative holes on the food portioning unit correspond one-to-one with the compartments on the food portioning drop unit, so that the food falling in each vertical channel can fall into the bowl at a predetermined position along a predetermined path, realizing the simultaneous quantitative portioning of multiple dishes and the automatic plating of multiple dishes in the same bowl.

[0010] The portioning unit for serving dishes has several measuring holes. By controlling the several measuring holes on one portioning unit to be staggered or overlapped with the channels of several dishes, the channels can be opened and closed simultaneously without the need to control the opening and closing of each channel individually. This simplifies the structure, improves control efficiency, and ensures the consistency of the opening and closing of each dish channel.

[0011] As a preferred embodiment of the present invention, the food storage unit includes a shell, a central cylinder is fixed inside the shell, the compartment of the food storage unit is a storage compartment, a plurality of storage compartments are arranged around the central cylinder, a stirring drive mechanism is installed inside the central cylinder, a stirring mechanism is arranged inside the storage compartment, and the stirring drive mechanism is driven by the plurality of stirring mechanisms.

[0012] Each storage compartment can store one type of dish, and each compartment is equipped with a heating function to keep the dishes warm before serving. The stirring drive mechanism in the central cylinder can synchronously drive the stirring mechanism in each storage compartment, achieving simultaneous stirring of multiple dishes. The stirring mechanism reduces bridging of dishes as they fall, breaking down any bridging structures and allowing the dishes to fall more naturally into the portioning unit.

[0013] As a preferred embodiment of the present invention, the stirring drive mechanism includes a stirring power mechanism installed inside the central cylinder, the output end of which is connected to a rotating wheel, and the rotating wheel is provided with a plurality of active levers; the stirring mechanism includes a stirring shaft rotatably connected to the side wall of the storage chamber, one end of the stirring shaft extending into the storage chamber is connected to a stirring paddle, and the other end of the stirring shaft extending out of the storage chamber is provided with a driven wheel, and the driven wheel is provided with a plurality of driven levers, with the active levers on the rotating wheel and the driven levers on the driven wheels being arranged alternately.

[0014] The stirring power mechanism drives the rotating wheel to rotate, thereby causing several active levers on the rotating wheel to simultaneously actuate several driven levers on the driven wheels. This, in turn, causes several stirring shafts to rotate synchronously, and the stirring in each storage compartment will stir the corresponding food items. This invention uses only one stirring power mechanism to drive all stirring paddles, has a reasonable structural arrangement, and can reduce the space occupied by the stirring drive mechanism.

[0015] As a preferred embodiment of the present invention, the bottom of the housing is provided with a pull-out groove, a pull plate is inserted into the pull-out groove, and a plurality of connecting holes are provided on the pull plate. When the pull plate is inserted, the plurality of connecting holes correspond one-to-one with the lower openings of a plurality of storage compartments.

[0016] When food is stored in several compartments but not needed for individual servings, the pull-out panel is pulled out a certain distance from the slot, completely misaligning the connecting holes with the bottoms of the compartments, thus closing the food delivery channels and preventing leakage. When individual servings are needed, the pull-out panel is pushed all the way back in, aligning the connecting holes with the bottoms of the compartments, opening the food delivery channels, and allowing for precise control of food quantity addition via the individual serving unit.

[0017] As a preferred embodiment of the present invention, the portioning unit includes a metering disc rotatably connected to the machine body, the metering disc having a plurality of metering holes, and a metering drive mechanism for driving the metering disc to rotate installed inside the machine body; the portioning unit includes a dropping hopper fixed inside the machine body, the compartments on the portioning unit being dropping compartments, the plurality of dropping compartments being separated by a plurality of partitions inside the dropping hopper, the top of the dropping hopper being provided with a fixing plate, the fixing plate being provided with a plurality of dropping holes, the plurality of metering holes being completely offset from the plurality of compartments of the portioning unit.

[0018] When the quantitative drive mechanism rotates the quantitative disc, several quantitative holes on the disc coincide with or are offset from the bottom of several storage compartments, enabling the synchronous opening and closing of several food channels. When the quantitative holes are connected to the storage compartments, food can be temporarily stored through the quantitative holes. When serving, the quantitative drive mechanism is restarted, and the quantitative holes and drop holes correspond one-to-one, allowing the temporarily stored quantitative food to fall into the drop holes of the serving food drop unit, thus enabling the addition of food. This invention achieves synchronous opening and closing of multiple food channels simply by driving the quantitative disc to rotate, eliminating the need for an opening and closing mechanism for each food channel.

[0019] In a preferred embodiment of the present invention, the quantitative driving mechanism includes a quantitative power mechanism installed within the machine body. The output end of the quantitative power mechanism is connected to a driving gear, and a driven gear is disposed on the quantitative disc. The driving gear meshes with the driven gear. When the quantitative power mechanism drives the driving gear to rotate, the driving gear meshes with the driven gear, thereby driving the quantitative disc to rotate.

[0020] As a preferred embodiment of the present invention, a baffle ring is fixed at the bottom of the falling bucket, and a bowl is placed on the output end of the lifting drive unit, with the baffle ring corresponding to the bowl.

[0021] As a preferred embodiment of the present invention, the lifting drive unit includes a lifting power mechanism installed in the machine body, the output end of the lifting power mechanism is connected to a cam disk, and an actuating column is fixed on the edge of the cam disk; a guide column is fixed in the machine body, a lifting frame is sleeved on the guide column, a transverse guide hole is provided on the lifting frame, the actuating column is inserted into the transverse guide hole, a support frame is fixed on the lifting frame, and a support frame for placing a bowl is provided at the other end of the support frame.

[0022] When the lifting mechanism drives the cam plate to rotate, the actuating column on the edge of the cam plate performs a combined lateral and longitudinal movement. Since the lifting frame is fitted onto the guide column, it can only move up and down. Because the actuating column is inserted into the lateral guide hole on the lifting frame, it can move laterally within the guide hole, while longitudinally it can push the lifting frame up and down. Thus, driven by the lifting mechanism, the support frame on the support frame can lift and lower the bowl. When serving, the support frame lifts the bowl from the bottom to a suitable position to prevent food from spilling when it falls into the bowl. After serving, the support frame is lowered to facilitate the removal of the bowl containing the food.

[0023] In a preferred embodiment of the present invention, a baffle mechanism is connected inside the machine body, and the support frame passes through the baffle mechanism. During the raising and lowering of the support frame, the baffle mechanism ensures that the inside and outside of the machine body are always isolated without obstructing the support frame, thus preventing food from falling into the machine body.

[0024] As a preferred embodiment of the present invention, the baffle mechanism includes a guide frame fixed inside the machine body, a guide groove is provided in the guide frame, a plurality of baffles are provided in the guide groove, and vertical holes are provided on the baffles; in one direction, the height of the plurality of baffles and the height of the vertical holes on the plurality of baffles all increase sequentially.

[0025] Several baffles are fitted into guide grooves in the guide frame, allowing them to move up and down within these grooves. Since the height of the baffles and the height of the vertical holes on them increase sequentially, the baffles are pushed upwards in sequence as the support frame rises, preventing interference with the support frame. When the support frame lowers, all baffles descend, isolating the internal and external spaces of the machine and preventing food from falling into the machine. Because of the multi-layered baffles and the sequentially increasing height of the baffles and the vertical holes, the distance between the top of each baffle and the top of the vertical hole can be reduced accordingly (the maximum distance between the support frame and the top of the machine frame). When each baffle rises and contacts the machine frame, the support frame rises further, reducing the distance between the bowl and the food distribution unit, preventing food spillage.

[0026] The beneficial effects of this invention are as follows: 1. When the food storage unit and the food quantity measuring unit of this invention are connected, the food automatically falls into the food quantity measuring unit. When the food fills the container of the food quantity measuring unit, quantitative temporary storage is achieved. The container of the food quantity measuring unit serves as a container for temporarily storing food. By setting the volume of the container of the food quantity measuring unit, the amount of each type of food can be controlled, thus achieving the purpose of quantitative food portioning.

[0027] 2. When serving food separately, the portioning unit begins to rotate until it connects with the food dropping unit, allowing the food to fall into the bowl. The portioning holes on the portioning unit correspond one-to-one with the compartments on the food dropping unit, ensuring that food falling through each vertical channel follows a predetermined path to a specific position in the bowl. This allows for the simultaneous portioning of multiple dishes and automatic plating of them within the same bowl.

[0028] 3. The portioning unit for serving dishes has several metering holes. By controlling the metering holes on one portioning unit to be staggered or overlapped with the channels of several dishes, the channels can be opened and closed simultaneously without the need to control the opening and closing of each channel individually. This simplifies the structure, improves control efficiency, and ensures the consistency of the opening and closing of each dish channel. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the invention can be combined with each other.

[0033] This invention is mainly applied to the commercial use of intelligent food portioning. It can quantitatively standardize a certain type of dish (such as carrot granules, corn kernels, pea granules, etc., which are drained and have no water or soup). It can also replace manual labor to automatically plate the dishes into several equal portions in a bowl 6 (such as distributing 5 kinds of dishes around the center of the bowl 6), reducing labor intensity and improving efficiency.

[0034] like Figures 1 to 11 As shown, the quantitative meal distribution device of this embodiment is characterized by: including a body 1, a meal distribution food storage unit 2 provided on the upper part of the body 1, a meal distribution food dropping unit 3 fixed inside the body 1, and a meal distribution food quantitative unit 4 installed inside the body 1 for controlling the opening and closing of the channel between the meal distribution food storage unit 2 and the meal distribution food dropping unit 3; a lifting drive unit 5 installed on the lower part of the body 1, the output end of the lifting drive unit 5 being aligned with the lower opening of the meal distribution food dropping unit 3; both the meal distribution food storage unit 2 and the meal distribution food dropping unit 3 have 5 compartments, and the meal distribution food quantitative unit 4 has 5 quantitative holes 411, with the 5 compartments of the meal distribution food storage unit 2, the 5 quantitative holes 411 on the meal distribution food quantitative unit 4, and the 5 compartments on the meal distribution food dropping unit 3 corresponding one-to-one.

[0035] Initially, the portioning unit 4 rotates until it connects with the portioning storage unit 2. The food automatically falls into the portioning unit 4, and when it fills the container, it is temporarily stored in portions. When portioning is needed, the bowl 6 is placed at the output of the lifting drive unit 5, which then raises the bowl 6. The portioning unit 4 begins to rotate until it connects with the portioning drop unit 3, and the food falls from the drop unit 3 into the bowl 6, achieving automatic plating. During the descent, the portioning storage unit and the portioning unit 4 are not connected. The portioning unit 4 then returns to its initial state.

[0036] The container of the portion control unit 4 serves as a temporary storage container for the dishes. By setting the volume of the portion control unit 4, the amount of each dish can be controlled.

[0037] Furthermore, the quantitative holes 411 on the food portioning unit 4 correspond one-to-one with the compartments on the food portioning falling unit 3, so that the food falling in each vertical channel can fall into the bowl 6 at a certain position according to a certain path, realizing the simultaneous quantitative portioning of multiple dishes and the automatic plating of multiple dishes in the same bowl 6.

[0038] The portioning unit 4 has several measuring holes 411. By controlling the several measuring holes 411 on one portioning unit 4 to be staggered or overlapped with the channels of several dishes, the channels can be opened and closed simultaneously without the need to control the opening and closing of each channel individually. This simplifies the structure, improves control efficiency, and ensures the consistency of the opening and closing of each dish channel.

[0039] Specifically, the food storage unit 2 includes a shell 21, a central cylinder 22 fixed inside the shell 21, a storage compartment 23 for the food storage unit 2, and several storage compartments 23 arranged around the central cylinder 22. A stirring drive mechanism 24 is installed inside the central cylinder 22, and a stirring mechanism 25 is arranged inside the storage compartment 23. The stirring drive mechanism 24 is driven by several stirring mechanisms 25.

[0040] Each storage compartment 23 can store one type of dish, and each storage compartment 23 has a volume of approximately 2L. Each storage compartment 23 is equipped with a heating function to keep the dishes warm before serving. The stirring drive mechanism 24 in the central cylinder 22 can synchronously drive the stirring mechanism 25 in each storage compartment 23 to achieve simultaneous stirring of multiple dishes. The stirring mechanism 25 can reduce bridging of dishes when they fall, breaking down bridging structures and allowing the dishes to fall more naturally into the portioning unit.

[0041] The stirring drive mechanism 24 includes a stirring power mechanism 241 installed inside the central cylinder 22. The output end of the stirring power mechanism 241 is connected to a rotating wheel 242, and the rotating wheel 242 is provided with a plurality of active levers 243. The stirring mechanism 25 includes a stirring shaft 251 rotatably connected to the side wall of the storage chamber 23. One end of the stirring shaft 251 extending into the storage chamber 23 is connected to a stirring paddle 252, and the other end of the stirring shaft 251 extending out of the storage chamber 23 is provided with a driven wheel 253. The driven wheel 253 is provided with a plurality of driven levers 254, and the active levers 243 on the rotating wheel 242 and the driven levers 254 on the driven wheels 253 are arranged alternately.

[0042] The stirring power mechanism 241 drives the rotating wheel 242 to rotate, thereby causing several active levers 243 on the rotating wheel 242 to synchronously actuate several driven levers 254 on several driven wheels 253. This, in turn, causes several stirring shafts 251 to rotate synchronously, and the stirring in each storage compartment 23 will stir the corresponding food items. This invention uses only one stirring power mechanism 241 to drive all the stirring paddles 252, resulting in a reasonable structural arrangement and reducing the space occupied by the stirring drive mechanism 24.

[0043] Furthermore, the bottom of the housing 21 is provided with a pull-out groove, into which a pull plate 7 is inserted. The pull plate 7 is provided with several connecting holes, and when the pull plate 7 is inserted, the several connecting holes correspond one-to-one with the lower openings of several storage compartments 23.

[0044] When food is stored in several storage compartments 23 but not needed for serving, the pull plate 7 is pulled out a certain distance from the pull-out slot, completely offsetting the bottoms of the several connecting holes from the bottoms of the several storage compartments 23, thus closing the food channel and preventing food leakage. When serving is needed, the pull plate 7 is pushed all the way down, completely aligning the bottoms of the several connecting holes with the bottoms of the several storage compartments 23, opening the food channel, and allowing precise control of the amount of food added through the food portioning unit 4.

[0045] Specifically, the portioning unit 4 includes a portioning disc 41 rotatably connected to the body 1, with five portioning holes 411 on the disc. A portioning drive mechanism 42 for driving the disc 41 to rotate is installed inside the body 1. The portioning unit 3 includes a dropping bucket 31 fixed inside the body 1. The compartments on the portioning unit 3 are dropping chambers 32. The five dropping chambers 32 are separated by several partitions inside the dropping bucket 31. A fixing plate 33 is provided on the top of the dropping bucket 31. Five dropping holes 331 are provided on the fixing plate 33. The five portioning holes 411 are completely offset from the five compartments of the portioning unit 2.

[0046] When the quantitative driving mechanism 42 drives the quantitative disk 41 to rotate, several quantitative holes 411 on the quantitative disk 41 coincide with or are offset from the bottom of several storage compartments 23, realizing the synchronous opening and closing of several food channels. When the quantitative holes 411 are connected to the storage compartments 23, the food can be temporarily stored through the quantitative holes 411. When it is necessary to divide the food into portions, the quantitative driving mechanism 42 is activated again, and the several quantitative holes 411 and several falling holes 331 correspond one-to-one. The temporarily stored quantitative food falls into the falling holes 331 of the food distribution falling unit 3, and the food can be added at this time. This invention can realize the synchronous opening and closing of multiple food channels by simply driving the quantitative disk 41 to rotate, without the need to set an opening and closing mechanism for each food channel.

[0047] The quantitative driving mechanism 42 includes a quantitative power mechanism 421 installed inside the body 1. The output end of the quantitative power mechanism 421 is connected to a driving gear 422, and a driven gear 412 is provided on the quantitative disk 41. The driving gear 422 meshes with the driven gear 412. When the quantitative power mechanism 421 drives the driving gear 422 to rotate, the driving gear 422 meshes with the driven gear 412, thereby driving the quantitative disk 41 to rotate.

[0048] A baffle ring 34 is fixed to the bottom of the falling bucket 31, and a bowl 6 is placed on the output end of the lifting drive unit 5, with the baffle ring 34 corresponding to the bowl 6.

[0049] Specifically, the lifting drive unit 5 includes a lifting power mechanism 51 installed in the body 1. The output end of the lifting power mechanism 51 is connected to a cam disk 52, and an actuating column 53 is fixed on the edge of the cam disk 52. A guide column 54 is fixed inside the body 1. A lifting frame 55 is sleeved on the guide column 54. A transverse guide hole 551 is provided on the lifting frame 55. The actuating column 53 is inserted into the transverse guide hole 551. A support frame 56 is fixed on the lifting frame 55. A support frame 57 for placing the bowl 6 is provided at the other end of the support frame 56.

[0050] When the lifting mechanism 51 drives the cam disk 52 to rotate, the actuating column 53 on the edge of the cam disk 52 performs a combined lateral and longitudinal movement. Since the lifting frame 55 is fitted onto the guide column 54, the lifting frame 55 can only move up and down. Because the actuating column 53 is inserted into the lateral guide hole 551 on the lifting frame 55, the actuating column 53 can move within the lateral guide hole 551, while in the longitudinal direction, the actuating column 53 can push the lifting frame 55 to rise and fall. Thus, driven by the lifting mechanism 51, the support frame 57 on the support frame 56 can drive the bowl 6 to rise and fall. When serving the food, the support frame 57 lifts the bowl 6 from the bottom to a suitable position to prevent the food from spilling when it falls into the bowl 6. After serving, the support frame 57 is driven down to facilitate the removal of the bowl 6 containing the food.

[0051] Furthermore, a baffle mechanism 8 is connected inside the machine body 1, and the support frame 56 passes through the baffle mechanism 8. During the lifting and lowering of the support frame 56, the baffle mechanism 8 ensures that the inside and outside of the machine body 1 are always isolated without obstructing the support frame 56, thus preventing food from falling into the machine body 1.

[0052] The baffle mechanism 8 includes a guide frame 81 fixed inside the body 1. A guide groove is provided inside the guide frame 81, and a plurality of baffles 82 are provided inside the guide groove. Vertical holes 821 are provided on the baffles 82. In one direction, the height of the plurality of baffles 82 and the height of the vertical holes 821 on the plurality of baffles 82 increase sequentially.

[0053] Several baffles 82 are fitted into the guide grooves of the guide frame 81, allowing them to move up and down within the guide grooves. Since the height of the baffles 82 and the height of the vertical holes 821 on the baffles 82 increase sequentially, the support frame 56 rises by sequentially pushing the baffles 82 from low to high, preventing interference between the baffles 82 and the support frame 56. When the support frame 56 lowers, all the baffles 82 descend, isolating the internal and external spaces of the machine body 1 and preventing food from falling into the machine body 1. Because multiple baffles 82 are used, and the height of several baffles 82 and the height of the vertical holes 821 on several baffles 82 increase sequentially, the distance between the top of each baffle 82 and the upper side of the vertical hole 821 can be reduced accordingly (the limit distance between the support frame 56 and the top of the frame of the machine body 1). When each baffle 82 rises and contacts the frame of the machine body 1, the height of the support frame 56 increases, reducing the distance between the bowl 6 and the food distribution unit 3, thus preventing the food from spilling.

[0054] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
