Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a weighing module installation structure and a kitchenware with weighing function. Background Technology

[0002] Air fryers are used for frying and baking food, while ovens are used for heating, steaming, and baking food; both are common kitchen appliances. Both types are available on the market with or without a weighing function. For those without a weighing function, the food must be weighed separately, which is inconvenient. Those with a weighing function come in two types: one with a weighing function on the top of the appliance, and the other with a weighing function at the bottom. The bottom-weighing appliance is more convenient because the food is weighed immediately after being placed inside, eliminating the need to weigh it on top first.

[0003] Currently, most air fryers or ovens on the market with bottom-mounted weighing functions require a specially designed structure for the weighing components. For example, the original base structure is modified to include a recessed mounting point at each of the four corners of the base, into which the four weighing components are then installed. This structure does not provide ideal protection for the weighing components, making them prone to damage and malfunction during actual use, thus affecting the reliability of the weighing function.

[0004] Furthermore, due to its reliance on the weighing circuit board on the base, the weighing sensors of each weighing component are connected to the weighing circuit board via a first line, and the weighing circuit board is then connected to the main circuit board in the main unit via a second line. With many wiring points and complex wiring, the probability of the weighing circuit board and any of its connected first or second lines becoming loose due to bottom collisions or other situations increases, further increasing the risk of unreliable weighing function, affecting user experience, and also increasing the cost of after-sales maintenance for manufacturers and retailers.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

Detailed Implementation

[0041] Please refer to Figures 1 to 10 As shown, it illustrates the specific structure of various embodiments of the present invention.

[0042] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] This article takes air fryers and ovens as examples to introduce the application structure of a weighing module installation structure in air fryers and ovens.

[0044] A weighing module installation structure includes a base plate 10 and a plurality of weighing modules 20 disposed on the base plate 10. Typically, the plurality of weighing modules 20 are arranged on the base plate 10 at horizontal intervals. For example, a set of weighing modules 20 is disposed at each of the four corners of the base plate 10.

[0045] The base plate 10 is generally made of plastic, but can also be made of metal or other materials. It serves as the mounting base for the weighing module 20 and as the base supporting the kitchenware body. The base plate 10 is provided with a number of horizontally spaced, vertically penetrating clearance holes 11 (for example, the vertical clearance holes 11 can be arranged in a triangular or rectangular quadrangular relationship). The top of the base plate 10 is arranged around the vertical clearance holes 11 with two or more upwardly extending module fixing posts 12. The top of the module fixing posts 12 is recessed with a first connecting hole 13.

[0046] The weighing module 20 includes a fixed base 21, a deformable block 22, a weighing sensor 23, and a support foot 24; wherein:

[0047] The fixing base 21 includes a top wall 211 and a peripheral side wall 212 connected to the bottom periphery of the top wall 211. The top wall 211 is provided with a through hole 213. The peripheral side wall 212 and the bottom surface of the top wall 211 form a receiving cavity 214. The peripheral side wall 212 has a stepped positioning surface 215, which is located between the bottom surface of the top wall 211 and the bottom of the peripheral side wall 212. The top wall 211 is also connected to a mounting wall 216, which is provided with a second connecting hole 217 that is through the top and bottom.

[0048] The deformable block 22 is a metal sheet such as an iron sheet or an aluminum sheet. The deformable block 22 includes an integrally connected fixed frame 221 and a suspension part 222 connected to the inner edge of the fixed frame 221. The fixed frame 221 is embedded in the receiving cavity 214 and the top surface of the fixed frame 221 is restricted by the step positioning surface 215. The suspension part 222 is located in the receiving cavity 214 and maintains a deformation gap 223 with the inner top surface of the receiving cavity 214.

[0049] The load cell 23 is glued and fixedly connected to the suspension part 222. The load cell 23 is connected to a weighing connection line 231, which passes through the wire hole 213 and extends above the top wall 211. Before assembly, the load cell 23 is usually glued and fixed to the deformable block 22, and the load cell 23 is attached to the weighing connection line 231 to form a sensing assembly. In actual installation, the load cell 23 can be glued and fixedly installed on the top surface of the suspension part 222, and the top wall 211 and the suspension part 222 completely cover the corresponding top and bottom of the load cell 23 to protect the load cell 23. Alternatively, the weighing sensor 23 can be glued and fixed to the bottom surface of the suspension part 222. The top of the support foot 24 has a first clearance position 241 and a second clearance position 242. The weighing sensor 23 is set corresponding to the first clearance position 241, and the suspension part 222 and the support foot 24 completely cover the corresponding top and bottom of the weighing sensor 23 to protect it. The weighing connecting line 231 passes through the second clearance position 242 and extends out from the wire passage hole 213. The outer edge of the fixing frame 221 maintains a first gap d1 with the inner surface of the peripheral side wall 212, and the outer edge of the fixing frame 221 maintains a second gap d2 with the inner wall surface of the vertical clearance hole 11. The weighing connecting line 231 passes through the second clearance position 242, the second gap d2, and the first gap d1 in sequence and extends out from the wire passage hole 213. The outer edge of the fixed frame 221 is provided with an arc-shaped notch d3. The arc-shaped notch d3 extends vertically through the upper and lower ends of the fixed frame 221. The arc-shaped notch d3 facilitates better guidance and positioning of the symmetrical connecting line 231. Moreover, when the deformable block 22 is embedded, the arc-shaped notch d3 allows for a small deformation of the outer periphery of the fixed frame 221. In this way, the assembly size requirements of the deformable block 22 and the fixed seat 21 are reduced, improving assembly efficiency and yield.

[0050] The support foot 24 is made of plastic or metal, usually integrally molded, but other suitable materials may also be used. The top of the support foot 24 is connected to the suspension part 222. The suspension part 222 is provided with a third connecting hole 2221, and the top of the support foot 24 is provided with a fourth connecting hole 2401. The third connecting hole 2221 and the fourth connecting hole 2401 are arranged opposite each other and connected to the third connecting hole 2221 and the fourth connecting hole 2401 by a second screw. In this way, the suspension part 222 is installed and fixed on the support foot 24. The top of the support foot 24 is provided with a first limiting wall 2402 around the fourth connecting hole 2401. The suspension part 222 is limited by the first limiting wall 2402 to limit the horizontal position of the suspension part 222 relative to the support foot 24. Furthermore, the top wall 211 is provided with a clearance hole 2111 corresponding to the cap of the second screw to allow space for the cap of the second screw, providing the vertical space required for deformation, so that the limited height of the weighing module can better meet the weighing needs of larger weights. Moreover, the clearance hole 2111 is designed as a through hole that runs vertically through the top wall 211, which also facilitates the tightening of the second screw through the clearance hole 2111. If it is necessary to replace the support foot 24, the entire weighing module 20 can be removed directly from the top of the fixed base 21 without disassembling the entire module 20, the new support foot 24 can be installed, and the second screw can be tightened from the top of the fixed base 21.

[0051] The weighing module 20 is arranged one by one with respect to the vertical clearance holes 11. The support foot 24 passes downward through the clearance holes and protrudes from the bottom of the base plate 10. The bottom surface of the fixing frame 221 is constrained by the base plate 10 and is clamped and positioned between the step positioning surface 215 and the base plate 10. The second connecting hole 217 is arranged with respect to the first connecting hole 13 and is connected to the first connecting hole 13 by the first screw. In this way, the fixing seat 21 and the entire weighing module 20 are installed and fixed on the base plate 10. In this embodiment, the mounting wall 216 is higher than the top wall 211. The periphery of the mounting wall 216 has an integrally downward extending second limiting wall 218 to form a limiting cavity 219. The module fixing post 12 extends into the corresponding limiting cavity 219. A wire-blocking rib 210 extends laterally integrally from the outer side of the second limiting wall 218. An inlet notch 210a is formed between the extended end of the wire-blocking rib 210 and the adjacent mounting wall 216. The inlet notch 210a is open upwards. A outlet groove 210b is formed below the wire-blocking rib 210. The inlet notch 210a connects to the outlet groove 210b to form an L-shaped groove. The weighing connecting wire 231 extends from the wire through hole 213 and passes through the outlet groove 210b to extend outside the fixing base 21. During wiring, the weighing connecting wire 231 is inserted into the inlet notch 210a and then its lateral movement is restricted by the area below the wire-blocking rib 210.

[0052] Furthermore, a kitchen appliance with a weighing function is provided, comprising a kitchen appliance body, the bottom of which is provided with a weighing module mounting structure as described above; the base plate 10 is disposed at the bottom of the kitchen appliance body to support the entire kitchen appliance body; a control system is disposed on the kitchen appliance body, and the weighing connection line 231 is connected from the inside of the kitchen appliance body to the control system to provide weight feedback; the kitchen appliance body is an air fryer body or an oven body.

[0053] like Figure 1 , 2 As shown in Figures 6 and 8, an air blaster with a weighing module mounting structure 100 at its bottom is displayed. The air blaster includes an air blaster body 200. The air blaster body 200 is a mature technology. The bottom of the outer peripheral sidewall of the air blaster body 200 can be connected to the periphery of the base plate 10, or other connection methods can be used, as long as they can be used to install and fix the air blaster body 200 on the base plate 10.

[0054] like Figure 10As shown, it displays an oven with a weighing module mounting structure 100 installed at the bottom. The oven includes an oven body 300. The oven body 300 is a mature technology. The bottom of the outer peripheral sidewall of the oven body 300 can be connected to the periphery of the base plate 10, or other connection methods can be used, as long as the oven body 300 can be installed and fixed on the base plate 10.

[0055] The key design feature of this utility model lies in its base plate and several weighing modules. Several clearance holes are provided on the base plate, and each weighing module is positioned corresponding to one of these vertical clearance holes. Support legs pass downwards through the clearance holes and protrude from the bottom of the base plate. The bottom surface of the fixing frame is constrained by the base plate, and the top surface of the fixing frame is constrained by the fixing seat. The fixing seat is locked to the base plate. The weighing module installation structure is simple and ingenious, providing stable and reliable installation and convenient wiring. The kitchen appliance body is simply placed on the base plate, and the weighing connection line is connected to the control system of the kitchen appliance body. It is easily applied to kitchen appliances such as air fryers and ovens. Therefore, the weighing module installation structure of this utility model is suitable for widespread application.

[0056] Furthermore, the structure and mutual assembly and positioning relationship of the fixed base, deformation block, load cell and support foot of the weighing module are cleverly designed to ensure that the load cell and wiring parts are effectively protected and are not prone to loosening due to collision, thus making the weighing function reliable.

[0057] Furthermore, the weighing module uses a weighing sensor, and its weighing connection cable can be directly connected to the original control system of the kitchen appliance body, eliminating the need for the original weighing circuit board on the base and reducing the possibility of damage or failure of the wiring parts and the weighing circuit board.
