Description

Technical Field

[0001] The utility model relates to the technical field of intelligent kitchens, in particular to a weighing device and kitchen equipment. Background Art

[0002] With the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for the quality of daily diet. The ratio of seasonings to ingredients in the cooking process is the main factor that determines the taste of food, making accurate control of the amount of seasoning used an important part of the cooking process. Existing automatic cooking equipment usually includes a seasoning module that can quantitatively discharge materials. After the seasoning module is used for a long time, it is easy to be affected by mechanical wear or seasoning viscosity, such as reduced discharge or material blockage. The cooking process is automatic, and users cannot find out whether the amount of seasoning is accurate in time, resulting in deviations in the taste of food. In the prior art, the seasoning module with a weighing component is often adjacent to the seasoning module in order to make the weighing accurate. However, on the one hand, the weighing component is easily contaminated by the seasoning, and the seasoning module is easily affected by the outside world, thereby affecting the weighing accuracy. On the other hand, the weighing component is built near the seasoning module. If the weighing component fails, it is difficult to replace and repair. On the other hand, the driving motor vibrates when discharging materials, which is very easy to affect the accuracy of the weighing component, making the weighing accuracy very low.

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects of the weighing device proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0035] On the one hand, if Figure 1-4 As shown, the embodiment of the utility model provides a weighing device for kitchen equipment, the weighing device comprising:

[0036] at least one weighing assembly (100), the weighing assembly comprising a weighing piece, the weighing piece comprising a first end and a second end opposite to each other, the first end of the weighing piece being fixedly connected to the kitchen equipment;

[0037] The feeding device (200) is used for storing and / or feeding materials, and the feeding device (200) is suspended at the second end of the weighing piece.

[0038] The kitchen device may be an intelligent cooking device, and the controller of the intelligent cooking device may store cooking programs for various dishes. When in use, the user puts the ingredients into the cooking space. After the user selects the dishes, the controller may control the actuator of the intelligent cooking device to perform steps such as stir-frying, frying, and boiling the ingredients according to the set steps, and automatically put in materials to assist cooking during the cooking process, thereby realizing automatic cooking. The materials may be seasonings, water, oil, starch, etc. The properties of the materials may be solid, such as powdered or granular salt and sugar, or liquid, such as soy sauce, vinegar, etc., or a solid-liquid mixture. The feeding device (200) may be used only to store materials, such as the feeding device (200) includes a tank body (210), the tank body (210) is used to hold materials, and the feeding device (200) may be connected to an additional material driving mechanism to output materials. Alternatively, the feeding device (200) includes, in addition to the tank body (210) that can hold materials, a material output device connected to the tank body (210).

[0039] The weighing assembly (100) includes a weighing piece, the first end of which is connected to the kitchen equipment, the weight of the feeding device (200) is applied to the second end of the weighing piece, and the weighing piece is used to output different detection results according to the external force applied to the second end, thereby realizing the detection of the weight change of the material stored in the tank (210), and realizing the monitoring of each feeding amount, and when the feeding amount does not meet the required amount of the cooking procedure of the dish, calibration and reminder can be performed. The feeding device (200) is suspended on the second end of the weighing piece, which means that the feeding device (200) only has a supporting relationship with the second end of the weighing piece, that is, the entire weight of the feeding device (200) is applied to the second end of the weighing piece, and then the actual change of the weight of the feeding device (200) can be detected by the weighing piece. The feeding device (200) can be connected to the second end of the weighing piece in a variety of ways, such as one or a combination of sleeve connection, plug connection, hanging connection, clamping connection and magnetic connection, or other connection methods, so that the entire weight of the feeding device (200) can act on the second end of the weighing piece. In addition, the feeding device (200) can be located above the second end of the weighing piece, and the weight is applied to the second end of the weighing piece by pressing down, or it can be directly or indirectly hung below the second end of the weighing piece, and the weight is applied to the second end of the weighing piece by hanging. In the above embodiment, compared with the prior art in which the weighing assembly (100) is built under the feeding device (200), the weighing assembly (100) is placed externally, making subsequent maintenance simpler and faster. The weighing assembly (100) is separated from the seasoning module, which also reduces the impact of the vibration of the driving motor on the weighing assembly (100) during feeding. At the same time, it prevents the leakage of seasoning in the feeding device (200) from causing the weighing assembly (100) under the feeding device (200) to be contaminated, greatly improving the accuracy of the weighing assembly (100) in weighing seasoning. In a more specific embodiment, the weight measuring piece detects the weight by deforming the second end due to the external force of the feeding device (200). For example, the weight measuring member includes a cantilever and a deformation sensor, the first end of the cantilever is connected to the kitchen equipment, and the second end of the cantilever is connected to the feeding device (200). The connection here can be a direct connection, such as the feeding device (200) is directly suspended on the second end of the cantilever; or it can be an indirect connection through an additional connection structure, ensuring that the weight of the feeding device (200) is completely applied to the second end of the cantilever. The deformation sensor is connected to the cantilever and is located between the first end and the second end of the cantilever. The second end of the cantilever moves under the weight of the feeding device (200), thereby causing the first end and the second end of the cantilever to deform. The deformation sensor is used to generate different output signals according to the degree of deformation of the cantilever, and then the change in the weight of the feeding device (200) can be determined according to the change in the output signal. For example, the deformation sensor can be a metal strain gauge sensor, a grating sensor, etc. The deformation sensor can be set on the surface of the cantilever, or inside the cantilever.When the deformation sensor follows the cantilever deformation, its conductive properties will change, that is, the output current or voltage will change.

[0040] When in use, the extension direction of the weighing piece from the first end to the second end may be horizontal, and the second end of the weighing piece will slightly move in the vertical direction under the action of the feeding device (200), thereby causing the weighing piece to bend to varying degrees. Alternatively, the extension direction of the weighing piece from the first end to the second end may be vertical, and the second end of the weighing piece will slightly move in the vertical direction under the action of the feeding device (200), thereby causing the weighing piece to be compressed to varying degrees. Both bending and compression can cause the shape of the surface of the cantilever to change, which can then be detected by a deformation sensor.

[0041] The number of weighing components (100) can be one or more, and the number of feeding devices (200) can also be one or more. A single weighing component (100) can correspond to multiple feeding devices (200). When in use, the feeding devices (200) that need to feed can be controlled to feed in a staggered manner. The weighing component (100) can detect the feeding accuracy of each feeding device (200). Alternatively, a single feeding device (200) can correspond to multiple weighing components (100), so that multiple weighing components (100) can jointly detect the accuracy of the feeding devices (200) to avoid misjudgment. Alternatively, the weighing components (100) and the feeding devices (200) can correspond one to one.

[0042] In some embodiments, the feeding device (200) is located above the second end of the weighing piece, and the weight is applied to the second end of the weighing piece by pressing down.

[0043] In one embodiment, the weighing device further comprises a support block (600), the support block (600) is connected to the first end of the weighing piece, the weighing piece is connected to the kitchen equipment through the support block (600), and then the area of ​​the weighing piece other than the first end is raised to avoid collision or contact between the weighing piece and the kitchen equipment when the second end of the weighing piece is moved by force, so as to avoid the kitchen equipment restricting the deformation of the weighing piece and affecting the weighing result. In some embodiments, a flexible buffer part is provided between the weighing piece and the feeding device (200) and between the weighing piece and the kitchen equipment, such as a gasket made of a flexible material. The flexible buffer part can alleviate the external force impact and wear on the weighing piece.

[0044] During the detection process, the weight information generated by the weighing piece is the sum of the weights of all the feeding devices (200) connected thereto, or when the feeding device (200) and the weighing piece are connected by including an additional connection structure, the weight information generated by the weighing piece is the sum of the weights of all the feeding devices (200) connected thereto and the connection structure. During the cooking process, only the weight change will occur due to the reduction of the material in the feeding device (200), and then the feeding amount can be monitored according to the weight difference before and after the feeding. For example, in this feeding, the weighing piece is used to generate the first weighing information before the feeding device (200) feeds, and the weighing piece is also used to generate the second weighing information after the feeding device (200) feeds, and the first weighing information and the second weighing information are used to determine the feeding amount. When the difference between the feeding amount and the standard feeding amount is not within the first preset threshold range, an alarm is issued to prompt the user that the feeding is abnormal, or calibration can be performed automatically or after receiving the user's instruction.

[0045] The utility model provides a weighing device and kitchen equipment, in which a feeding device for discharging materials is connected to the kitchen equipment through a weighing component. The weighing component can detect the weight change of the feeding device before and after the feeding device feeds materials, and then obtain the actual weight value of the feeding, thereby realizing the monitoring of the feeding amount. When the feeding is inaccurate, timely feedback can be given, so that the user can make timely adjustments to avoid cooking failure.

[0046] In one embodiment, the weighing assembly includes a flexible housing (110) which at least partially surrounds a weighing member.

[0047] The weighing piece is set close to the cooking area, and there will be floating attachments such as oil smoke and water vapor in the environment. The attachments will adhere to the weighing piece, affecting the weighing accuracy of the weighing piece, or if the sensor is affected, it may also cause failure. The flexible shell (110) is used to block the weighing piece from the external environment, and can prevent the attachments from contacting the weighing piece, thereby ensuring the cleanliness of the weighing piece and ensuring the accuracy and life of the weighing piece. The flexible shell (110) can be set on a single side of the weighing piece, such as on the side close to the cooking area; or it can surround the weighing piece and be set in a part of the area corresponding to the deformation sensor of the weighing piece; or it can wrap the entire weighing piece.

[0048] At least a part of the flexible shell (110) is deformable. During the operation of the weighing piece, the second end of the weighing piece will deform relative to the first end. The flexible shell (110) can follow the deformation of the weighing piece through its own deformation, thereby avoiding obstruction to the deformation of the weighing piece and not pulling the second end of the weighing piece, thereby ensuring the sensitivity of the weighing piece. The flexible shell (110) can be made of a flexible material, such as foam, soft rubber, etc., and can also be flexible through changes in its own structure, such as a part of the area can be connected in sequence by multiple hinges, and the flexible shell (110) is made flexible as a whole through the relative movement between adjacent hinges.

[0049] In one embodiment, the second end of the weighing piece is fixedly connected or detachably connected to the feeding device (200). The second end of the weighing piece and the feeding device (200) can be fixedly connected by bolts, or can be hung, clamped, magnetically connected, plugged, or the second end of the weighing piece supports the feeding device (200), so that the feeding device (200) can be easily picked up and moved.

[0050] The feeding device (200) can be in various forms, such as having only the functions of storage and discharge, being unable to discharge materials by itself, and being connected to an external driving device to drive the discharge of materials; or having the functions of storage, driving and discharge, and being able to drive the materials to move and discharge by itself. The following are examples of two forms of feeding devices (200):

[0051] In one embodiment, if Figure 1-2 As shown, the feeding device (200) includes a tank body (210) and a feeding pipe (220), wherein the feeding pipe (220) is connected to and communicates with the tank body (210), the tank body (210) is used to store materials, and the feeding pipe (220) is used to transfer the materials in the tank body (210).

[0052] The feed pipe (220) may be a hose, and the tank body (210) may be used to hold liquid seasonings, and the feed pipe (220) may be connected to an external pump body to drive the material, such as a peristaltic pump, etc. Alternatively, the tank body (210) may be connected to an air pump, and then a certain amount of gas may be filled into the tank body (210) to squeeze out the material.

[0053] In another embodiment, if Figure 3-4 As shown, the feeding device (200) includes a tank body (210) and a feeding device (230), wherein the feeding device (230) is connected to and communicates with the tank body (210), the tank body (210) is used to store materials, and the feeding device (230) is used to discharge materials in the tank body (210).

[0054] The feeding device (230) can be a variety of structures that can actively push the material to move. The tank body (210) can be used to hold solid seasonings, such as salt, monosodium glutamate, etc. In one embodiment, the feeding device (230) includes a shell, a driving member, and a pushing part. The shell includes a feeding cavity and a feeding port connected to the feeding cavity. The shell is connected and connected to the discharge port of the tank body (210). The feeding device (230) is located near the bottom of the tank body (210). The driving member is connected to the pushing part, and the pushing part can be a structure similar to a screw. The driving member drives the pushing part to rotate, and then the material falling from the tank body (210) into the shell of the feeding device (230) can be pushed to move, and then move to the feeding port for feeding. Or there can be other embodiments.

[0055] The weighing device may include both of the above-mentioned two feeding devices (200) at the same time, and may be used to feed solid seasonings and liquid seasonings; or, the weighing device may include only one of the above-mentioned feeding devices (200).

[0056] In one embodiment, if Figure 1 As shown, the tank body (210) is provided with a holding portion (211), and the holding portion (211) is used to facilitate the placement and movement of the tank body (210). The holding portion (211) can be a depression or protrusion opened on the tank body (210), or it can be an additional component such as a handle connected to the tank body (210). More specifically, the tank body (210) can be a roughly cubic structure, and the holding portion (211) can be a recessed area set on two adjacent edges of the tank body (210), and then the tank body (210) can be picked up and moved through the holding portion (211) by pinching, which is easy to operate.

[0057] In one embodiment, the weighing device further comprises a weighing platform (400), and the weighing platform (400) is used to carry the feeding device (200). The weighing platform (400) is fixedly connected or detachably connected to the second end of the weighing member.

[0058] The weighing platform (400) can be connected to multiple positions of the second end of the weighing piece. For example, in an embodiment where the first end to the second end of the weighing piece is horizontally placed, the weighing platform (400) can be arranged above the second end of the weighing piece, or arranged below the second end of the weighing piece, such as being arranged below the second end of the weighing piece in a hanging manner. Alternatively, in some embodiments, the first end to the second end of the weighing piece is vertically arranged, and the weighing platform (400) can be arranged above the end of the second end of the weighing piece, that is, it can be arranged on the end surface. The connection between the weighing platform (400) and the second end of the weighing piece can be a fixed connection, such as a bolt connection, or a detachable connection such as a hanging connection, a clamping connection, a plug-in connection, or a magnetic connection. By setting the weighing platform (400), it is possible to facilitate the connection and placement of the feeding device (200). The feeding device (200) can be a universal feeding device (200), which can be connected to the weighing piece through the weighing platform (400).

[0059] In one embodiment, a plurality of feeding devices (200) are provided in the weighing platform (400). In order to avoid uneven force on the weighing piece and the weighing piece being skewed, the extension direction of the weighing piece from the first end to the second end is the first direction, and the weighing piece can be arranged in the middle position of the weighing platform (400) in the second direction, and the second direction is perpendicular to the first direction, so that the force on the weighing piece is balanced and the torque is reduced. A plurality of feeding devices (200) can be arranged in the second direction. For example, when there are three feeding devices (200), the three feeding devices (200) are arranged perpendicular to the weighing piece, and the weighing piece corresponds to the middle feeding device (200). The number of feeding devices (200) can be even greater, but it should be ensured that they are not too far away from the weighing piece to avoid the influence of excessive torque on the weighing result.

[0060] In one embodiment, the weighing platform (400) includes a containing shell, which at least partially surrounds the tank body (210).

[0061] The containment shell plays a role in protecting, isolating and supporting the tank body (210), and can reduce the pollution of attachments and external interference, such as avoiding accidental touching of the tank body (210); can isolate the influence of the outside world on the weighing of the tank body (210); can support the entire or multiple tank bodies, and facilitate the weighing of the seasoning as a whole. The containment shell can be an open cavity structure with an opening at one end, which can facilitate the taking and placing of the tank body (210). The opening of the containment shell can be set on the side of the containment shell opposite to the weighing piece, or can be on the side opposite to the cooking area, thereby reducing the pollution of attachments. The tank body (210) can be tightly abutted in the containment shell, and abutted against the inner wall of the containment shell, thereby preventing the tank body (210) from shifting or falling. The aforementioned feed pipe (220) or feed discharge device (230) may be connected only to the tank body (210), and extend from the clearance opening on the containment shell to the outside of the containment shell, and then feed; or, the feed pipe (220) or feed discharge device (230) may be connected to the containment shell, and at least the discharge opening is located outside the containment shell, opposite to the cooking area. The feed pipe (220) or feed discharge device (230) includes a docking device or a docking port inside the containment shell, and when the tank body (210) is placed inside the containment shell, it will be connected to the docking device or the docking port and connected by docking, so that when performing operations such as refilling, there is no need to disassemble and assemble the feed pipe (220) and the feed discharge device (230). A sealing member, such as foam or soft rubber, may be provided at the position where the feed pipe (220) or feed discharge device (230) passes through the containment shell, so as to reduce the amount of attachments that enter the containment shell through the gap and contaminate the tank body (210).

[0062] In one embodiment, the weighing assembly includes a limiting member (300), a material pipe opening (411) is provided on the containing shell, and the material delivery pipe (220) passes through the material pipe opening (411) to communicate with the external pump body. The material delivery pipe (220) may include a hose, and the external pump body may be a peristaltic pump, etc., which can then drive the liquid material in the tank body (210) to flow out. A sealing member may be provided between the material pipe opening (411) and the material delivery pipe (220). In order to make the weighing assembly have certain flexibility and versatility, the material delivery pipe (220) is usually a flexible hose, and the shape of the material delivery pipe (220) can be adjusted as needed to adapt to the position of different cooking areas and the fixed position of the weighing assembly. The limiting member (300) is used to act with the material delivery pipe (220) to play the role of positioning and supporting the material delivery pipe (220), so as to prevent the flexible deformation of the material delivery pipe (220) and the swing in an uncertain direction, which affects the installation and measurement accuracy.

[0063] The limiting member (300) can limit the feed pipe (220) in various ways, such as providing a limiting hole (310) on the limiting member (300), and after the feed pipe (220) is led out from the feed pipe opening (411), it passes through the limiting hole (310) of the limiting member (300), and then the limiting is achieved. The limiting hole (310) can be a circular hole, and the inner diameter of the limiting hole (310) is slightly larger than the outer diameter of the feed pipe (220), such as 0.5 mm, 1 mm, etc., which will not affect the transmission of the material in the feed pipe (220) and play a role in limiting the feed pipe (220). Alternatively, a limiting notch can be provided on the limiting member (300), and the notch is an arc-shaped notch that matches the outer wall wheel of the feed pipe (220), and then the feed pipe (220) can be limited in a supporting manner.

[0064] The relative position of the limiting member (300) and the feeding device (200) is fixed, thereby stabilizing the position of the feeding pipe (220). The limiting member (300) can be connected to a variety of positions, such as being connected to kitchen equipment, or being connected to the containing shell of the weighing platform (400) to limit the movement of the feeding pipe (220). The limiting member (300) can be a plate-like structure, and can be integrally formed with the containing shell, thereby simplifying the structure and facilitating installation.

[0065] In one embodiment, the material delivery pipe (220) extends straight in the area between the material pipe opening (411) and the limiting member (300), thereby avoiding bending that may cause obstruction in material transmission, affect the accuracy of material feeding, and avoid misjudgment of the weighing component.

[0066] In one embodiment, a material discharge opening is provided at the bottom of the accommodating shell, and the material discharge opening corresponds to a material discharge port of the material discharge device (230).

[0067] In the embodiment where the feeding device (230) is located inside the housing, the solid or semi-liquid material overflowing from the feeding port of the feeding device (230) will be put into the cooking area through the corresponding feeding opening, thereby preventing the feeding device (230) from being exposed and easily contaminated by oil stains and steam. By opening the feeding opening at the bottom of the housing, the housing can be cleaned separately. The housing structure is relatively simple, easy to clean, and can better protect the complex structure such as the driving parts in the feeding device (230).

[0068] In one embodiment, the weighing device further comprises: a connecting frame (500), the connecting frame (500) is connected to the weighing platform (400), and an installation space is provided between the connecting frame (500) and the weighing platform (400). The second end of the weighing piece extends into the installation space, and the weighing piece is connected to the weighing platform (400) via the connecting frame (500).

[0069] The structure of the connecting frame (500) can be various. For example, in one embodiment, the length direction of the connecting frame (500) is perpendicular to the extension direction from the first end to the second end of the weighing piece, or in other words, the connecting frame (500) extends in the extension direction of multiple feeding devices (200), thereby achieving a better and more stable connection between the weighing platform (400) and the weighing piece, increasing the connection strength, and increasing the uniformity of the force on the weighing piece. The height of the installation space between the connecting frame (500) and the weighing platform (400) in the deformation direction of the weighing piece is greater than the height of the weighing piece in its own deformation direction. If the weighing piece extends in the horizontal direction, and the second end of the weighing piece is used to move in the vertical direction under the action of the feeding device (200), the deformation direction of the weighing piece can be regarded as the vertical direction. The vertical space of the installation space is larger than the height of the second end of the weighing piece, so that there is a gap between the second end of the weighing piece and the weighing platform (400). The gap prevents the weighing platform (400) from hindering the deformation of the weighing piece, thereby preventing the deformation of the weighing piece from contacting the weighing platform (400) and affecting the weighing result. The extension amount of the connecting frame (500) in the extension direction from the first end to the second end of the weighing piece is much smaller than the extension amount of the weighing platform (400) in the extension direction from the first end to the second end of the weighing piece. The influence of the connecting frame (500) on the weighing piece is very small and can be ignored.

[0070] As described in the above embodiments, a buffer portion may be provided between the connecting frame (500) and the weighing piece. The connecting frame (500) and the weighing piece may be connected by a plurality of bolts. In some embodiments, the connecting frame (500) may be a frame structure including a plurality of hollow parts, thereby reducing the weight of the connecting frame (500) and the basic deformation of the weighing piece caused by the connecting frame (500), thereby placing the weighing piece within a measurement range with a better sensitivity, thereby ensuring the accuracy of measuring the feed amount.

[0071] In an embodiment where the weighing assembly (100) is connected to a plurality of feeding devices (200), the following method may be used for calibration:

[0072] In this feeding, the weighing component (100) is used to generate first weighing information before the feeding device (200) feeds, and the weighing component (100) is also used to generate second weighing information after the feeding device (200) feeds. The first weighing information and the second weighing information are used to determine the total feeding amount, and the total feeding amount may be generated by the feeding device (200) feeding, or may be generated by multiple feeding devices (200) feeding.

[0073] When the difference between the total feeding amount and the standard feeding amount is not within a first preset threshold range, calibration is performed, specifically including: if the feeding is performed by a single feeding device (200), a first prompt message is generated, and the feeding device (200) corresponding to the feeding is automatically calibrated; if the feeding is performed by two or more feeding devices (200), a first prompt message is generated, and the feeding devices (200) are controlled to feed in sequence according to the single measurement preset amount. For each feeding, the weighing component (100) is used to generate original weighing information before the current feeding device (200) feeds, and to generate final weighing information after the current feeding device (200) feeds. The original weighing information and the final weighing information are used to determine the single measurement actual amount corresponding to the current feeding device (200). When the difference between the single measurement actual amount and the single measurement preset amount is not within a second preset threshold range, the current feeding device (200) is automatically calibrated.

[0074] After calibration, the feeding device (200) is controlled to feed materials according to the target repetitive measurement, and the weighing component (100) is used to generate third weighing information before the feeding device (200) feeds materials, and the weighing component (100) is also used to generate fourth weighing information after the feeding device (200) feeds materials. The third weighing information and the fourth weighing information are used to determine the actual repetitive measurement, and when the difference between the actual repetitive measurement and the target repetitive measurement is not within the third preset threshold range, indicating that normal calibration cannot be performed, a second prompt information is generated, and a user can manually perform calibration or troubleshooting.

[0075] On the other hand, an embodiment of the utility model provides a kitchen device, comprising one or more weighing devices in any one of the above items.

[0076] The kitchen device includes any of the aforementioned weighing devices, including the advantages of any of the aforementioned weighing devices, which will not be repeated here.

[0077] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
