Description

Technical Field

[0001] The present invention relates to a weighing device, particularly a weighing device that can be connected to a food processing apparatus (or similar machine for processing materials) to weigh food in the food processing apparatus. Background Technology

[0002] Weighing ingredients before, during, and after food processing is a crucial step in the process. Therefore, adding weighing functions to food processing equipment such as food processors and vertical mixers is advisable.

[0003] One solution has been proposed in the applicant's patent publication number GB2435411A. This disclosure proposes a vertical mixer with integrated weighing function and display screen. However, this cannot be retrofitted to existing machines.

[0004] The applicant's patent publication number GB2436876A proposes an alternative solution. This disclosure discloses a food processing apparatus whose container support surface is configured to accommodate the legs of a kitchen scale. However, this does not ensure a secure connection between the weighing device and the food processing apparatus, and requires removing the food from the processing location for weighing, which can be cumbersome and time-consuming.

[0005] Another suggested solution is to place a weighing device below the food processing unit to add weighing functionality. However, this method has a problem: there is no connection between the weighing device and the food processing unit, meaning the food processing unit could potentially fall off the weighing device. Furthermore, the fluid ports / openings of the food processing unit (e.g., vents and drains) could become clogged by the weighing device.

[0006] The present invention aims to at least partially improve the aforementioned problems in the prior art. Summary of the Invention

[0007] According to one aspect of this application, a weighing device is provided for supporting a machine used to process materials, the weighing device including a through hole (also referred to herein as a first opening and a second opening). This allows fluid to pass through the weighing device.

[0008] The weighing device is best used independently. The through-hole can be configured to allow fluid to drain through it during use. The through-hole may extend through the entire weighing device. That is, the through-hole can extend from one outer surface or part of the weighing device to another outer surface or another part of the weighing device.

[0009] The through-hole can be configured to allow fluid to flow through the weighing device. The weighing device may also include a surface for supporting a machine used to process materials, with the through-hole located on this surface. This surface may be located on a first side of the weighing device, facing the machine when the weighing device is mounted on it. The weighing device may also include a bottom surface, with the through-hole extending from the surface to the bottom surface. This bottom surface may be located on another side of the weighing device, facing the surface supporting the weighing device.

[0010] The area of ​​the through-hole on the surface is preferably less than 50% of the total surface area, more preferably less than 25%, more preferably less than 10%, and even more preferably less than 5%. The area of ​​the through-hole on the bottom surface is preferably less than 50% of the total bottom surface area, more preferably less than 25%, more preferably less than 10%, and even more preferably less than 5%. The through-hole preferably extends from the surface in a direction perpendicular to the surface. The through-hole preferably extends from the bottom surface in a direction perpendicular to the bottom surface. The through-hole is preferably straight. The through-hole preferably has a generally circular cross-section, more preferably a standard circular cross-section.

[0011] The weighing device may further include an inclined portion for guiding fluid flow to a through-hole; preferably, the inclined portion is located on a surface; more preferably, the inclined portion surrounds the through-hole. The weighing device may further include multiple weighing units; preferably, at least three weighing units; more preferably, four weighing units. The through-hole may be located between at least two of the multiple weighing units.

[0012] The weighing device may also include one or more accessories for detachably connecting the weighing device and the machine used to process the material.

[0013] The weighing device may also include a peripheral wall; preferably arranged to accommodate liquid (in the case that the liquid remains on the surface of the weighing device without being discharged through the through hole).

[0014] The weighing device may also include one or more additional through holes, preferably with a diameter / area smaller than the aforementioned through holes. Therefore, the one or more additional through holes can be configured as auxiliary drainage holes (or ventilation holes). The one or more additional through holes can be configured to align with corresponding openings in the machine.

[0015] According to one aspect of this application, a system is provided comprising: a weighing device as described above and a machine for processing materials. The weighing device and the machine may be configured to be detachably connected together, preferably with the machine for processing materials supported by the weighing device. The machine may include an opening, and the system may be configured to provide a fluid passage between the opening and a through-hole when the weighing device is detachably connected to the machine.

[0016] According to one aspect of this application, a system is provided comprising: a machine for processing materials, the machine including an opening; and a weighing device including an additional opening; wherein the weighing device and the machine are configured to be detachably connected together, preferably, the machine for processing materials is supported on the weighing device; and the system is configured to provide a fluid passage through the opening and the additional opening / provide a fluid passage between the opening and the additional opening when the weighing device and the machine are detachably connected together.

[0017] The weighing device and the machine preferably each include means for detachable connection with each other; preferably a connector; more preferably a pin and socket connector. The machine can be a food processing machine.

[0018] According to one aspect of this application, a food processing apparatus is disclosed, comprising a machine (preferably a food processor) for processing materials and a weighing device detachably connected to the machine / food processor. When the weighing device is connected to the machine / food processor, it is configured such that a first opening (i.e., a through-hole) of the weighing device is in fluid communication with a second opening of the food processor. The advantage of this arrangement is that it adds weighing functionality to the food processor while reducing obstruction to fluid flow within the weighing device.

[0019] The fluid passage can extend from a part of the machine to the outside of the weighing device, which is used to receive containers for storing materials to be processed. The location and arrangement of the opening and another opening / through hole allow the weighing device and the machine / food processor to be substantially aligned when connected together.

[0020] Optionally, the device may also include a fastener configured to detachably connect the weighing device to the food processor, the fastener preferably extending through a first opening / through-hole when the weighing device is connected to the machine / food processor. This creates a compact structure. The fastener can be configured to secure the weighing device and the machine at the first opening / through-hole and the opening on the machine. That is, the fastener can be configured to secure the weighing device and the machine through the first opening / through-hole and the opening on the machine, preferably by engaging with a fastening structure (preferably threaded) provided in the first opening / through-hole and the opening on the machine.

[0021] Preferably, the fastener has one or more channels for guiding fluid flow. This further reduces the possibility of fluid flow obstruction.

[0022] The fastener may optionally include threads for engaging with corresponding threads to secure the food processor to the weighing device.

[0023] In an optional configuration, the thread extends only to a portion of the fastener's circumference, preferably allowing the fastener to be securely screwed into place with less than one rotation, thereby securing the weighing device to the machine / food processor. This is achieved by engaging with a thread on the weighing device and / or the machine / food processor, which similarly extends only around a portion of the fastening structure's circumference. The advantage of this is that it reduces the number of rotations required to secure the fastener into place.

[0024] In a preferred configuration, the channel is defined along the unthreaded portion of the fastener. This is a particularly efficient and compact configuration.

[0025] The fastener can optionally be a manually operated fastener. Therefore, the use of tools can be avoided.

[0026] Preferably, one of the first and second openings is a drain hole or a vent hole. Therefore, drainage and / or ventilation may be improved.

[0027] Alternatively, the first opening may be a drain hole, which is configured to guide liquid from the food processor to the outside of the weighing device.

[0028] Preferably, the weighing device includes an electronics compartment and a waterproof barrier located between the electronics compartment and the first opening / through-hole. This reduces damage to the electronic components.

[0029] The weighing device may optionally include one or both of the following: - An integrated display for showing the weighing results; - A wireless communication module used to transmit weighing results to external devices.

[0030] Therefore, users can more easily view the weighing results output by the weighing device.

[0031] Preferably, the weighing device includes an internal power supply, preferably composed of a battery. Therefore, the practicality of the weighing device can be improved, and the use of power cords and mains power connections can be avoided.

[0032] In an optional configuration, the weighing device includes a food processor base configured to house a food processor, the shape of which directs fluid flow onto the base toward a first opening / through-hole. Therefore, residual liquid can still be drained. The food processor base may include the aforementioned inclined portion.

[0033] Preferably, the device may further include a weighing platform configured to receive raw materials to be weighed by the weighing device. That is, the weighing device may include a detachable weighing platform; preferably, the weighing platform is configured to be connected to the weighing device through a through-hole.

[0034] Optionally, the weighing platform can be detachably connected to the weighing device. This avoids the need to install a dedicated weighing component on the weighing device to act as the weighing platform.

[0035] Optionally, the first opening is a through-hole extending from a first side of the weighing device (facing the food processor when the weighing device is connected to it) to a second side of the weighing device (facing the surface supporting the weighing device). This can enhance fluid flow.

[0036] In one alternative arrangement, the positions and arrangement of the first and second openings ensure that they are substantially aligned when the weighing device and the food processor are connected to each other. This enhances fluid flow.

[0037] Preferably, the second opening is in fluid communication with the container of the food processor. This allows for easier and safer handling of liquid spills from the container.

[0038] Preferably, when connected to the food processor, the weighing device extends substantially beyond the coverage area of ​​the food processor. This ensures that the coverage area of ​​the food processor is covered. Preferably, the weighing device is configured such that, when connected to the food processor, the coverage area of ​​the food processor substantially overlaps with the coverage area of ​​the weighing device.

[0039] Preferably, one of the food processor and the weighing device includes a protrusion configured to engage with a recess in the other, further securing one to the other. This allows the food processor and the weighing device to be more securely connected.

[0040] Optionally, the weighing device is configured to support the food processor on a flat surface when connected to it.

[0041] The weighing device may also optionally include one or more legs. When the food processor is placed on the weighing device, the one or more legs are used to create a gap between the main body of the weighing device and the supporting surface, thereby allowing fluid to flow under the weighing device.

[0042] Preferably, the support legs are connected to a weighing unit used to weigh the weighing device and the object it supports. The advantage of using the support legs at the bottom of the weighing device to weigh an item is that the weighing is more accurate because all the weight is borne by the support legs.

[0043] Optionally, the support legs include anti-slip elements, optionally configured to grip the surface supporting the weighing device; preferably, the anti-slip elements are rubber anti-slip elements. This can improve the stability of the weighing device.

[0044] According to another aspect of this application, a parts kit for converting a food processor into a weighing food processor is disclosed, comprising: a weighing device as described above, and detachable fasteners for connecting the weighing device to the food processor.

[0045] According to another aspect of this application, a component kit for converting a food processor into a weighing food processor is disclosed, the kit comprising: Weighing device, and Removable fasteners for attaching the weighing device to the bottom of the food processor. The weighing device has one or more through holes for conveying fluid from the food processor to the outside of the weighing device.

[0046] According to another aspect of this application, a method for enabling a food processor to have a weighing function is disclosed, comprising the following steps: providing a food processor, a weighing device as described above, and fasteners; positioning the food processor on the weighing device such that the through hole of the weighing device is in fluid communication with the opening of the food processor; and connecting the food processor to the weighing device using fasteners.

[0047] According to another aspect of this application, a method for enabling a food processor to have a weighing function is disclosed, the method comprising the following steps: a) Provide food processing machines, weighing devices, and fasteners; b) Place the food processor on the weighing device such that the opening of the weighing device is in fluid communication with the opening of the food processor; and c) Use fasteners to connect the food processor to the weighing device.

[0048] Any device feature described herein can also be provided as a method feature, and vice versa. As used herein, means plus functional features can also be represented by their corresponding structures, such as a properly programmed processor and corresponding memory.

[0049] Any feature in one aspect of the invention may be applied to other aspects of the invention in any suitable combination. Specifically, a method aspect may be applied to an apparatus aspect, and vice versa. Furthermore, any, some, and / or all features in one aspect may be applied to any, some, and / or all features in any other aspect in any suitable combination.

[0050] It should also be understood that any particular combination of the various features described and defined in any aspect of this invention may be implemented and / or provided and / or used independently.

[0051] Unless otherwise stated, the word "or" in this specification may indicate exclusion or inclusion.

[0052] Furthermore, functionality implemented in hardware can often also be implemented in software, and vice versa. Any software and hardware features mentioned in this article should be explained accordingly.

[0053] Although this invention has been described in the field of household food processing and preparation machinery, it can also be applied to any field requiring efficient, effective, and convenient preparation and / or processing of materials, whether on an industrial scale or in small batches. The scope of application includes the preparation and / or processing of the following substances: chemicals; paints; building materials; clothing materials; agricultural and / or veterinary feed and / or therapeutic agents, including fertilizers, grains, and other agricultural and / or veterinary products; oils; fuels; dyes; cosmetics; plastics; tar; coatings; waxes; varnishes; beverages; solders; alloys; wastewater; and / or other substances, and any reference to “food” herein can be replaced by such working media. Therefore, although this invention is described primarily with reference to food processing machines, it should be understood that this invention can also be applied to any suitable machine for processing materials. Therefore, the terms “food processing machine” and “machine” are used interchangeably herein.

[0054] This invention can be applied to any kitchen appliance and / or used as a standalone device.

[0058] Figure 1 A food processing apparatus 100 according to an embodiment of the present invention is shown. The apparatus 100 includes a food processor 200 (in this example, a generally "C"-shaped vertical mixer), a weighing device 300 located below the food processor 200 to support the food processor on its upper surface 310, and fasteners 400 for securing the food processor 200 and the weighing device 300 together.

[0059] The food processor 200 has a base 210 from which a vertical portion 220 extends. The head 230 of the food processor 200 extends horizontally and is suspended above the base 210. The base 210 has an upward-opening bowl-shaped seat 211, serving as a container connection location to accommodate a bowl 500 (or other suitable container). The head 230 has a downward-facing drive outlet 240, opposite to and extending toward the bowl-shaped seat 211. An eccentrically positioned tool connection location 241 is provided on the drive outlet 240, to which a tool 600 (e.g., a mixer, whisk, or other rotating tool) can be connected to extend into the bowl 500 to process the food / beverage contained within.

[0060] The bowl-shaped base 211 may include heating or cooling elements for heating or cooling the contents of the bowl 500. The food processor 200 may have a support 213 extending downward from the base 210 to support the food processor 200 when used separately from the weighing device 300.

[0061] like Figure 1 As shown, the weighing device 300 is positioned on the support leg 320 during use. The support leg 320 is connected to the weighing unit 321 embedded within the weighing device 300, so that the load supported by the support leg 320 is also applied to the weighing unit 321, thereby being sensed and the weight data supported by the support leg 320 is output. In this way, the total weight of all objects supported by the support leg 320 can be detected, including (when the food processing device 100 is fully assembled) the food processor 200 and the bowl 500 supported by the food processor 200, as well as the food in the bowl.

[0062] The weighing device 300 can display weight data to a user via a user interface 330. This can be a touchscreen display or the like. Optionally or alternatively, a wireless module (not shown) of the weighing device 300 can transmit weight data to a mobile electronic device.

[0063] When the food processor 200 processes food in the bowl 500, food material may be dispersed into the bowl-shaped seat 211. Especially during heating, it is undesirable for spilled material to accumulate there, as it may overflow into the compartments of the food processor 200 containing potentially damaged electrical components. Therefore, the bowl-shaped seat 211 is provided with a bowl-shaped seat drain hole 212 to allow material splashed into the bowl-shaped seat 211 to drain through this hole 212. To maximize the use of gravity to help food / beverage material drain through the food processor 200, the bowl-shaped seat drain hole 212 is preferably positioned approximately vertically through the base 210.

[0064] When connecting the weighing device 300, it should not obstruct the fluid flow path of the food processor 200 so that food / beverage substances can be properly discharged from the food processor 200. However, to receive the weight of the food processor 200 for weighing, the weighing device 300 is preferably located below it. In fact, to fully support the weight of the food processor 200, the weighing device 300 should ideally cover the bottom of the food processor 200 when connected, preferably covering its entire base, which improves weighing accuracy.

[0065] To allow liquid to drain properly from the food processor 200, the upper surface 310 of the weighing device 300 (i.e., the surface supporting the food processor 210) is provided with an inclined recess 311 (also called an inclined portion). When the weighing device 300 is connected to the food processor 200, an opening 312 is provided in the recess, which is in fluid communication with the drain hole 212 of the bowl. Therefore, the hole 212 and the opening 312 provide a fluid channel (allowing fluid to flow from the bowl through the drain hole 212 and the opening 312 to the outside (below) of the weighing device).

[0066] The opening 312 extends through the weighing device (i.e., from the upper surface 310 to the lower surface), and is therefore referred to herein as a through-hole. This means that liquid flowing from the food processor 200 can flow through the weighing device 300. The through-hole 312 neither obstructs the flow of fluid from the food processor 200 nor allows liquid to flow freely across the upper surface 310 of the weighing device 300, which could potentially damage the electronic components in the user interface 330. The angled recess 311 also facilitates downward flow of fluid through the opening 312.

[0067] The through-hole 312 is located approximately on the longitudinal centerline of the weighing device 300, roughly near the front of the weighing device. Specifically, the opening 312 is located approximately at one-third of the length of the weighing device. The through-hole 312 is roughly aligned with, or slightly forward of, the two front legs of the device, i.e., between the left and right front legs. The through-hole 312 is preferably small relative to the coverage area of ​​the weighing device—its area may be less than 5% of the total coverage area of ​​the device 300.

[0068] To ensure the shortest and most convenient flow path for the liquid discharged from the food processor 200, the through-hole 312 and the drain hole 212 are preferably aligned so that the liquid can flow directly from one opening to the other. Preferably, they are arranged vertically as shown in the figure to enhance fluid flow. Preferably, they are in direct contact (i.e., the surfaces of each opening / hole are in contact, and when surfaces are in contact, the openings / holes are aligned), such as... Figure 3 As shown. Optionally or additionally, openings such as auxiliary openings 312a may be provided. These openings are not aligned with the drain hole 212 but are located within the recessed portion 310a of the upper surface 310, allowing liquid flowing from the drain hole 212 to flow laterally along the recessed portion 310a of the upper surface 310 until reaching the auxiliary opening 312a. The recessed wall also prevents liquid flowing towards the through hole 312 from overflowing onto the user interface 330. The auxiliary opening 312a may also provide additional openings to prevent the flow rate of fluid flowing from the drain hole 212 from exceeding the flow rate through the main through hole 312.

[0069] To prevent the food processor 200 from overheating / overcooling, it is best to provide ventilation through the weighing device 300. When the weighing device 300 is connected to the food processor 200, the main through-hole 312 and the auxiliary opening 312a also contribute to the ventilation of the food processor 200, for example, by allowing cold air to flow through the food processor 200 and cool it.

[0070] One or more recesses 313 may be formed on the upper surface 310 of the weighing device, sized to accommodate the support member 213 of the food processor 200, such that the recesses 313 and the support member 213 form a mating / fixing element, thereby allowing the weighing device and the food processor to be detachably connected. This interlocking of the support member 213 and the recesses 313 promotes stability and connection between the food processor 200 and the weighing device 300. The support member 213 may optionally be a suction cup foot, and the inner surface of the recesses 313 may be flat so that the support member 213 can be suctioned when placed on it, thereby forming a more secure connection between the two. Optionally or additionally, the recesses 313 may also be through holes to allow for further fluid flow.

[0071] like Figure 3 As shown, a circular and / or inclined upward protrusion 314 may be formed on the upper surface 310 of the weighing device 300. When the weighing device 300 and the food processor 200 are connected, the protrusion 314 can be accommodated in a corresponding recess 214 of the food processor 200. Similar to the interlocking of the support member 213 and the recess 313, this interaction between the protrusion 314 and the recess of the food processor 200 also promotes a firm connection between the two. In particular, when the through hole 312 concentrically passes through the protrusion 314 and the recess 214 of the food processor 200 is concentric with the drain hole 212, the inclined interaction helps to guide the alignment of the through hole 312 with the drain hole 212 when the food processor 200 is mounted onto the weighing device 300.

[0072] The weighing device 300 and the food processor 200 are secured together by fasteners 400, thereby detachably locking / secured the detachable accessory between the weighing device and the food processor. Figure 1 and Figure 4 As shown, fastener 400 is a threaded fastener. Fastener 400 secures the weighing device 300 to the food processor 200 by passing through the drain hole 212 of the bowl seat and into the drain hole 312 of the weighing device. Fastener 400 is preferably a threaded fastener with a gripping portion 401 that protrudes upward from one side of its flange 402. In use, the flange 402 abuts against the surface of the bowl seat 211 to secure the food processor in place. The gripping portion 401 allows the fastener 400 to be screwed into place without tools, improving convenience. The flange 402 may include radially extending reinforcing ribs 403 to increase strength.

[0073] To simplify the structure and improve the convenience of the device 100, the openings through which the fastener 400 for securing the weighing device 300 to the food processor 200 extends can be a drain hole 212 and a through hole 312. However, depending on the size of the holes and the fastener 400, this may also impede the flow of fluid through the through hole 312 and the drain hole 212 to some extent. To mitigate the potential obstruction to fluid flow, a downwardly extending cylindrical element is provided on the other side of the flange 402, a portion of which is formed with threads 404. A fluid channel 405 extends axially along the cylindrical element, lies between the various portions of the threads 404, and radially passes through the flange 402 along the gripper 401. Therefore, fluid can flow along the channel 405 through the fastener 400, allowing fluid flow even if the size of the fastener 400 is designed to span the width of the through hole 312 and the drain hole 212.

[0074] Screwing threaded fasteners into place by hand can be strenuous for users because initially only a portion of the threaded post axially engages with the corresponding thread at the beginning of the threaded hole. Multiple rotations may be required to achieve sufficient thread engagement for a sufficiently secure connection between the threaded post and the threaded hole it is attached to. To address this issue, fastener 400 has threads 404 only on a portion of its circumferential surface. The through-hole 312 has corresponding threads 312a on a portion of its inner circumferential surface. When connecting the food processor 200 to the weighing device 300, the fastener 400 can be inserted into the opening 312 through the drain hole 212, allowing the threads 404 of the fastener 400 to slide into the unthreaded portion of the inner surface of the through-hole 312. Once the fastener 400 is fully inserted into the drain hole 212 and the through-hole 312, it can be rotated to simultaneously interlock the threads 404 with the corresponding threads 312a along its entire axial direction, significantly reducing the amount of rotation required to achieve a secure connection.

[0075] Channel 405 can form the unthreaded portion of fastener 400. This simplifies the structure of fastener 400 while improving its practicality.

[0076] like Figure 2a As shown, the protrusion 314 may have a mark indicating the amount of rotation required to bring the thread 404 into contact with the corresponding 312a for tight engagement (in this case, approximately 1 / 10 to 1 / 6 of a full rotation). A similar mark may be provided in the cup-shaped seat 211.

[0077] Figures 2a to 2c A method for assembling a food processing apparatus 100 to add a weighing function to a food processor 200 is described.

[0078] like Figure 2aAs shown, a weighing device 300 is provided below the food processor 300 to receive and substantially cover the area covered by the food processor 200. The support member 213 of the food processor 200 is aligned with the recess 313 of the weighing device 300, and the protrusion 314 of the weighing device 300 is aligned with the recess 214 at the bottom of the food processor 200. Due to the alignment of these reference points, the drain hole 212 is aligned with the through hole 312.

[0079] like Figure 2b As shown, the food processor 200 is placed vertically on the weighing device 300. The interlocking of the support member 213 and the recess 313, as well as the interlocking of the protrusion 314 and the recess 214, helps to fix the food processor 200 on the horizontal surface of the weighing device 300.

[0080] exist Figure 2c In this configuration, the fastener 400 is vertically inserted through the drain hole 212 into the through hole 312 and rotated so that the thread 404 engages with the corresponding thread 312a, and the flange 402 of the fastener 400 abuts against the cup-shaped seat 211. In this way, the food processing machine 200 is fixed on the vertical plane of the weighing device 300.

[0081] The bowl-shaped base 211 includes a retaining element 211a for engaging with a corresponding element on the bowl 500 to secure the bowl 500 to the food processor 200. The retaining element 211a may include an interlock switch that prevents or restricts the operation of the food processor 200 (e.g., by preventing the motor of the drive tool 600 from starting, or preventing the heating element in the bowl-shaped base 211 from starting) unless the bowl 500 is properly secured by the retaining element 211a to activate the interlock switch.

[0082] The position of the fixing element 211a can be configured such that when the food processor 200 is placed on the weighing device 300, if the fastener 400 is located in the drain hole 212 but not fully engaged with the thread 312a, the fastener 400 will protrude from the drain hole 212 to prevent the bowl 500 from being connected to the fixing element 211a. This allows the user to clearly see that the fastener 400 is not fully engaged, and that the food processor 200 and the weighing device 300 are not properly connected. When used in conjunction with the aforementioned interlock switch function, if the fastener 400 is located in the drain hole 212 but not fully engaged with the corresponding thread 312a, the operation of the food processor 200 will also be prevented. An additional interlock switch can be installed on the food processor 200 to first detect the presence of the weighing device 300, and secondly to prevent the food processor 200 from operating when the weighing device 300 is present but the food processor 200 is not secured to the weighing device 300 using the fastener 400. When the electronic processor of the food processor 200 detects the presence of the weighing device 300 but the fastener 400 is missing, it can respond to this situation by displaying feedback to the user through the user interface (not shown) of the weighing device, indicating that the fastener 400 should be used.

[0083] Figure 5 The bottom surface (i.e., bottom side) of the weighing device 300 is shown, on which a support foot 320 is provided. The function of the support foot 320 is to create a gap between the surface on which the weighing device 300 is placed and the main body housing of the weighing device 300 (including the electronic components and user interface 330 associated with the weighing support foot 320). In this way, the electronic components of the weighing device 300 are protected from liquid leakage onto the surface on which the weighing device 300 is located through the drain hole 212 and the through hole 312.

[0084] The weighing device 300 also includes its own power supply within its main housing. In this case, the battery 342 is housed within the battery housing 340 and is sealed by the battery cover 341 (e.g., Figure 3 (As shown). Optionally or additionally, the weighing device 300 can also receive mains power via a suitable cable.

[0085] Figure 6A detailed view of one of the support legs 320 is shown. It can be seen that the support leg 320 has a support element 322 that connects to the “M”-shaped load sensing element 321a of the weighing unit 321, with the connection point located at the outermost “point” of the “M” shape. The load sensing element 321a is a force-sensitive resistor whose resistance changes when a load is applied causing it to bend. Connecting the support element 322 to the load sensing element 321a at the point of maximum span away from its connection to the housing of the weighing device 300 (i.e., at the outermost point of the “M” shape) maximizes the length of the load sensing element 321a used for sensing the load, thereby improving its load sensing characteristics. The support element 322 is connected to the load sensing element 321a by a fixing element 323 (e.g., a screw). Feedback from the weighing unit 321 is transmitted to the central processing unit of the weighing device 300 via an electrical connector 324. The foot element 322 is preferably made of a material with a high coefficient of friction, such as natural or synthetic rubber, to prevent the weighing device 300 from sliding on its surface. Optionally or additionally, the foot element 322 may also be a suction cup foot to enhance the fixation of the weighing device 300 on its surface.

[0086] Figure 7 Another configuration of the weighing device 300 is shown, in which a separate weighing platform 700 is connected to the weighing device 300. Material can be placed on the platform 700 as described above and weighed by the weighing unit 321. The platform 700 is similar to the fastener 400, except that it lacks the flange 402 and is instead composed of a wider platform element 701 with raised edges 701a to help hold the material on the platform 701. Because the platform 700 also has a threaded cylindrical screw element, it can be positioned in a through-hole 312, its threads engaging with a corresponding thread 312a in the through-hole 312, thus securely fixing it to the weighing device 300. The platform 700 is preferably made of a dishwasher-safe, food-safe material.

[0087] Although food processor 200 is described as a vertical blender, it can be replaced by other kitchen appliances without changing the basic principle of device 100. For example, food processor 200 can be a rotary chopper, juicer, toaster, kettle, or other kitchen appliance.

[0088] Fastener 400 is described as a threaded fastener, but other fasteners, including bayonet fasteners, nut-bolt devices, etc., may also be used. Manually operated fasteners (e.g., rotatable fasteners) are preferred to avoid the use of tools. It is best to provide fastener 400 as a separate component so that it does not need to be included when the weighing device 300 or food processor 200 is separate; however, it can also be attached to them to avoid loss.

[0089] As used herein, the term "detachable" (and similar terms such as "detachable connection"), when used to describe a connection between a first object and a second object, preferably means that the first object is connected to the second object and can be detached (preferably reconnected, detached again, etc., repeatedly), and / or the first object can be removed from the second object without damaging either the first or the second object; more preferably, the term means that the first object can be reconnected to the second object without damaging either the first or the second object, and / or the first object can be removed from the second object by hand and / or without tools (e.g., screwdrivers, wrenches, etc.) (and optionally, can also be reconnected to the second object). For this purpose, mechanisms such as snap-fit ​​connections, plug-in connections, and manually rotating locking nuts can be used.

[0090] In this article, "food safe" means any substance that, even if ingested, will not release substances harmful to human health, and the amount of release is clinically significant. For example, it should be BPA-free. "Machine washable" means that its physical and chemical properties should remain stable under long-term dishwasher use conditions. For example, it should be able to withstand mixtures of water and typical dishwashing detergents (e.g., with Fairy). TM Or Finish TM The dishwashing tablets and water were washed at 82 degrees Celsius for up to 8 hours without significant degradation (e.g., cracking).
