Description

Technical Field

[0001] This invention relates to the field of kitchen cooking appliances, and in particular to a gas stove with a high-precision weighing function. Background Technology

[0002] A gas stove is a common kitchen appliance that uses liquefied petroleum gas, manufactured gas, natural gas, or other gaseous fuels to heat food over a direct flame. Traditional gas stoves, however, do not allow real-time monitoring of the weight of the food inside the pot, making it difficult for the user to adjust cooking methods based on the weight of the food, leading to various inconveniences.

[0003] Based on this, existing technologies include gas stoves with weighing functions. For example, Chinese patent application CN115164241A discloses a weighing gas stove, which includes a gas stove housing, a base, and a panel. A weighing component is provided between the base and the panel. The weighing component includes a weighing sensor and a bracket for fixing the weighing sensor. At least one side of the weighing sensor is connected to the corresponding base and / or panel via the bracket. In the above solution, the weighing component is used to detect the force exerted on the panel by an item on it, thereby obtaining the weight information of the item. This structural design has the following defects and shortcomings:

[0004] ① The working principle of this weighing component is as follows: When the cooking pot is placed on the panel or pot support, the force exerted by the pot on the pot support or panel causes the support of the weighing component to deform, which in turn causes the weighing sensor to deform under force. Finally, the weight of the pot is measured based on the amount of deformation of the weight sensor. This detection method requires the weight of the pot to be indirectly measured based on the amount of deformation of the support. It is greatly affected by factors such as the structural strength of the support and the assembly weight. The structural design is complex and the detection accuracy is not high.

[0005] ② The load cells in the weighing assembly are fixedly connected to the panel and / or chassis only by the brackets on the upper and lower sides. They have insufficient shock resistance and poor structural stability. Under long-term use, the bracket structure is prone to deformation, which in turn affects the detection accuracy of the load cells.

[0006] Therefore, there is an urgent need to invent a gas stove with high detection accuracy and good structural stability in the existing technology. Summary of the Invention

[0007] In order to overcome the technical problems of low detection accuracy and poor structural stability in the prior art, the present invention provides a gas stove with high-precision weighing function. The gas stove with high-precision weighing function has the characteristics of simple and reasonable structural design, high detection accuracy, strong shock resistance and good structural stability.

[0008] The technical solution adopted by this invention to solve its problem is:

[0009] A gas stove with high-precision weighing function, comprising:

[0010] A panel, wherein the panel is provided with several circular openings;

[0011] A fixed bracket includes an assembly part and a sensor mounting bracket. The assembly part has an opening in the middle. The sensor mounting bracket is fixedly connected to the assembly part and is disposed at the opening. The assembly part is fitted and fixedly disposed on the bottom side of the panel.

[0012] A weighing module, comprising a weighing sensor and a sensor bracket, wherein the weighing sensor is fixedly mounted on the sensor mounting bracket and the sensor bracket is fixedly mounted on the weighing sensor;

[0013] The sensor bracket extends upward through the circular stove opening so that its top height exceeds the height of the panel, and a pot rack is provided on the top of the sensor bracket.

[0014] In a first optional embodiment of the present invention, a technical solution is provided regarding the setting of the number of weighing sensors, the setting of their location, and the electrical connection method.

[0015] The number of sensor fixtures, weighing sensors, and sensor supports are equal and greater than or equal to two, and multiple sensor fixtures are evenly arranged around the periphery of the opening.

[0016] Furthermore, the various weighing sensors are electrically connected by wires to form a full-bridge circuit.

[0017] In a second optional embodiment of the present invention, a technical solution is provided regarding the specific structural configuration of the weighing module.

[0018] The weighing module further includes a pressing structure. The top of the sensor holder is recessed downward to form an assembly groove. The weighing sensor is disposed in the assembly groove. The pressing structure is fixedly disposed on the top of the sensor holder to press the weighing sensor into the assembly groove.

[0019] Furthermore, the assembly slot is provided with a first through hole that passes through the sensor mounting bracket, and the first through hole is used to provide space for the weighing sensor to deform downward.

[0020] In a third optional embodiment of the present invention, a technical solution is provided regarding the specific structural configuration of the liquid tray, the stove body, and the burner assembly.

[0021] The gas stove with high-precision weighing function also includes a burner cap and a liquid collection tray. The burner cap is located on top of the circular burner opening, and the liquid collection tray is located between the burner cap and the weighing sensor.

[0022] Furthermore, a gap is provided between the bottom of the pot rack and the top of the panel, and an annular protrusion is provided on the outer periphery of the liquid tray. The annular protrusion is disposed in the gap, and the bottom of the annular protrusion is closely attached to the top of the panel.

[0023] Furthermore, the top of the liquid-holding tray is provided with a downwardly recessed groove, which is located at the bottom of the circular stove opening and is used to hold objects that fall from the circular stove opening.

[0024] Furthermore, the top of the liquid-holding tray is provided with several protrusions that protrude upward relative to the groove. Each protrusion has a second through hole, and the sensor bracket passes upward through the through hole so that the pot rack is positioned on top of the sensor bracket.

[0025] Furthermore, the gas stove with high-precision weighing function also includes a stove body and a burner assembly. The panel is fixedly installed on the top of the stove body, the burner assembly is installed inside the stove body, and the burner cap is installed on the top of the burner assembly.

[0026] In summary, the gas stove with high-precision weighing function provided by the present invention has at least the following technical advantages compared with the prior art:

[0027] 1) The working principle of the gas stove with high-precision weighing function provided by the present invention is as follows: When cooking, the cooking pot is placed on top of the pot rack. Since the bottom of the pot rack is in direct contact with the sensor bracket, the cooking pot exerts a downward force on the pot rack under the action of gravity. The pot rack exerts the same downward force on the sensor bracket, causing the sensor bracket to press positively on the weighing sensor, thereby causing the weighing sensor to deform. Finally, the weight of the cooking pot can be directly and in real time measured. Compared with the existing technology that places the weighing sensor inside the stove body or at the bottom of the stove body, the present invention directly measures the weight of the cooking pot by means of contact between the pot rack and the sensor bracket. The structural design is simple and reasonable and can significantly improve the weighing measurement accuracy.

[0028] 2) In the gas stove with high-precision weighing function provided by the present invention, the weighing sensor is fixedly mounted on the sensor mounting bracket of the fixed support. The fixed support is fixedly mounted on the bottom side of the panel through its assembly part, thereby realizing the fixed assembly of the weighing sensor. In this structural design, the sensor mounting bracket serves as a support structure for the weighing sensor. The assembly part and the panel are closely attached and fixedly connected over a large area. Therefore, the weighing sensor, the fixed support, and the panel are combined to form an integrated structure, which can significantly improve the shock resistance of the fixed support and the weighing module, and the structure has good stability and is not prone to structural deformation under long-term use. Furthermore, even if the fixed support undergoes structural deformation, since the deformation of the weighing sensor is only related to the downward force exerted by the pot rack on the sensor support, it will not affect the detection value of the weighing sensor, thereby further improving the detection accuracy of the weighing sensor.

[0029] 3) The gas stove with high-precision weighing function provided by this invention has multiple circular burners, each with a corresponding fixed bracket and weighing module. This allows for the separate weight detection of cooking utensils on each burner. Compared to a design where the weighing module is placed on the bottom shell of the stove, this invention can accurately measure the weight of each cooking utensil, rather than simply determining the total weight of all utensils placed on the gas stove. Furthermore, by combining the weighing sensor, fixed bracket, and panel into an integrated structure, the weighing measurement function can be achieved even with the panel serving as a fixed support structure. This makes the gas stove of this invention suitable for embedded applications, where the panel is fixed to the stove platform and the stove body is embedded inside. A design where the weighing module is placed on the bottom shell of the stove is not suitable for this application scenario. Attached Figure Description

Detailed Implementation

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", 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 invention 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 invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] See Figure 1 As shown, according to an embodiment of the present invention, a gas stove with high-precision weighing function includes a panel 1, which has a plurality of circular burners. The number and position of these circular burners can be determined according to the user's actual needs, with one circular burner corresponding to one cooking position. Furthermore, the panel 1 is preferably made of glass.

[0042] See Figure 3 , Figure 5 and Figure 6As shown, the gas stove with high-precision weighing function also includes a fixed bracket 2. The fixed bracket 2 includes an assembly part 21 and a sensor mounting bracket 3. An opening 22 is provided in the middle of the assembly part 21. The sensor mounting bracket 3 is fixedly connected to the assembly part 21 and is located at the opening 22. The assembly part 21 is fitted and fixedly disposed on the bottom side of the panel 1. Specifically, the assembly part 21 of the fixed bracket 2 and the bottom side (or back side) of the panel 1 are closely fitted and fixedly connected, with a large contact area between them, thereby fixing the fixed bracket 2 to the bottom side of the panel 1. More specifically, the assembly method between the fixed bracket 2 and the panel 1 can be fixedly connected by ultrasonic or other welding methods, or the panel 1 and the fixed bracket 2 can be processed into an integral structure during the production of the gas stove. The specific assembly method is not limited in this invention. In addition, a sensor mounting bracket 3 is fixedly connected to the assembly part 21 and is disposed on the outer periphery of the opening 22. The sensor mounting bracket 3 is a structure that extends and protrudes from the assembly part 21 toward the opening 22, which is used to provide assembly space for the weighing module and to provide support. Similarly, the assembly part 21 and the sensor mounting bracket 3 can be fixedly connected by welding or other means, or they can be set as an integrated structure during production.

[0043] See Figure 1 , Figure 3 and Figure 6 As shown, the gas stove with high-precision weighing function also includes a weighing module, which includes a weighing sensor 4 and a sensor bracket 41. The weighing sensor 4 is fixedly mounted on the sensor mounting bracket 3, and the sensor bracket 41 is fixedly mounted on the weighing sensor 4. The sensor bracket 41 extends upwards through the circular opening of the panel 1, so that the top height of the sensor bracket 41 exceeds the height of the panel 1, thereby ensuring that the top of the sensor bracket 41 can be used to place the pot rack 5. Specifically, the sensor bracket 41 is a vertically arranged rod-shaped or strip-shaped structure, and after installation, the top heights of all sensor brackets 41 are equal.

[0044] In this embodiment, when using a gas stove with high-precision weighing function, the cooking pot (or cooking utensil) is placed on top of the pot rack 5. Since the bottom of the pot rack 5 is in direct contact with the sensor bracket 41, the cooking pot exerts a downward force on the pot rack 5 under gravity (the magnitude of this force is the weight of the cooking pot). The pot rack 5 exerts the same downward force on the sensor bracket 41, causing the sensor bracket 41 to press against the weighing sensor 4, thereby causing the weighing sensor 4 to deform. Ultimately, the weight of the cooking pot 4 can be directly and in real time measured. Compared to the existing technology that places the weighing sensor inside the stove body or at the bottom of the stove body, this invention directly measures the weight of the cooking pot through the contact between the pot rack 5 and the sensor bracket 41. The structural design is simple and reasonable and can significantly improve the weighing measurement accuracy. Furthermore, the present invention can also provide a display module on panel 1 to display the weight data of the cooking pot in real time; it can also achieve data communication through the controller and external smart device, allowing users to understand the weight information and weight change information on the pot rack in real time through the smart device, thereby changing the weight of the ingredients according to actual needs and improving the cooking effect.

[0045] Furthermore, in this embodiment, the load cell 4 is fixedly mounted on the sensor mounting bracket 3 of the fixed support 2. The fixed support 2 is then fixedly mounted on the bottom side of the panel 1 via its assembly part 21, thereby achieving the fixed assembly of the load cell 3. In the above structural design, the sensor mounting bracket 3 of the fixed support 2 serves as a support structure for the load cell 4. The assembly part 21 of the fixed support 2 and the panel 1 are closely fitted and fixedly connected over a large area. Therefore, the load cell 4, the fixed support 2, and the panel 1 are combined to form an integrated structure, which can significantly improve the shock resistance of the fixed support 2 and the weighing module, resulting in good structural stability and reducing the likelihood of structural deformation during long-term use. Moreover, even if the fixed support 2 undergoes structural deformation, the deformation of the load cell 4 is only related to the downward force exerted by the pot frame 5 on the sensor support 41, thus not affecting the detection value of the load cell 4 and further improving the detection accuracy of the weighing module.

[0046] Furthermore, since the gas stove provided by this invention has multiple circular burners, each with a corresponding fixed bracket 2 and a weighing module, the weight of the cooking utensils on each burner can be measured separately. Compared to a design where the weighing module is placed on the bottom shell of the stove, this invention can accurately measure the weight of each cooking utensil, rather than simply determining the total weight of all the utensils placed on the gas stove. Moreover, by combining the weighing sensor, fixed bracket 2, and panel 1 into an integrated structure, the weighing measurement function can be achieved even with the panel 1 serving as a fixed support structure. This allows the gas stove of this invention to be adapted for embedded applications, where the panel 1 is fixed to the stovetop, and the stove body 8 is partially embedded inside the stovetop. A design where the weighing module is placed on the bottom shell of the stove is not suitable for this application scenario.

[0047] Example 1

[0048] In a first optional embodiment of the present invention, a technical solution is provided regarding the setting of the number, position, and electrical connection method of the weighing sensors 4.

[0049] In this embodiment, the number of sensor holders 3, weighing sensors 4, and sensor brackets 41 are equal, and each of the three is greater than or equal to two. One sensor holder 3 corresponds to one weighing sensor 4, and one weighing sensor 4 corresponds to one sensor bracket 41. The multiple sensor holders 3 are evenly arranged around the periphery of the opening 22, meaning the weighing sensors 4 and sensor brackets 41 are also evenly arranged around the periphery of the opening 22. Specifically, the opening 22 is a circular opening, and the even arrangement of the sensor holders 3 means that the sensor holders 3 are evenly spaced along the circumference of the opening 22. For example, when the number of sensor holders 3 is two, the line connecting the two sensor holders 3 is the diameter of the opening 22; when the number of sensor holders 3 is three, the line connecting the three sensor holders 3 is an equilateral triangle; and when the number of sensor holders 3 is four, the line connecting the four sensor holders 3 is a square (see [link to relevant documentation]). Figure 3 (As shown); similarly, the lines connecting multiple sensor holders 3 can form a regular polygonal structure. This structural design ensures that the pot frame 5 exerts uniform force on each sensor support 41, thereby unifying the deformation of each weighing sensor 4 and improving weighing accuracy.

[0050] In a preferred embodiment, the weighing sensors 4 are electrically connected by wires to form a full-bridge circuit, so that the total weighing range can be obtained by adding the ranges of the weighing sensors 4, that is, the weight data of the cooking utensils (including the food placed inside) placed on the pot rack 5 can be obtained by adding the measured data of the weighing sensors 4.

[0051] Example 2

[0052] In a second optional embodiment of the present invention, a technical solution is provided regarding the specific structural configuration of the weighing module.

[0053] See Figure 3 and Figure 4 As shown, in this embodiment, the weighing module further includes a pressing structure 32. The top of the sensor mounting bracket 3 is recessed downwards to form an assembly groove 31. The weighing sensor 4 is disposed in the assembly groove 31, and the pressing structure 32 is fixedly disposed on the top of the sensor mounting bracket 3 to press the weighing sensor 4 into the assembly groove 31. Specifically, when installing the weighing sensor 4, the weighing sensor 4 is first placed in the assembly groove 31, and then the pressing structure 32 is fixedly installed on the top of the sensor mounting bracket 3. At this time, the bottom of the pressing structure 32 and the top of the weighing sensor 4 abut against each other, thereby pressing the weighing sensor 4 into the assembly groove 31, completing the fixed assembly operation of the weighing sensor 4. More specifically, both the pressing structure 32 and the sensor mounting bracket 3 are provided with screw holes, allowing bolts, screws, or other connecting components to pass through the pressing structure 32 and the sensor mounting bracket 3 sequentially from top to bottom, thereby fixing the pressing structure 32 and the sensor mounting bracket 3 together.

[0054] See Figure 4 As shown, in a preferred embodiment, the assembly groove 31 is provided with a first through hole 33 that passes through the sensor mounting bracket 3. This first through hole 33 provides space for the load cell 4 to deform downwards. Specifically, when the cooking pot is placed on top of the pot rack 5, the sensor bracket 41 presses against the load cell 4, causing the load cell 4 to deform downwards, thereby detecting and obtaining weight information based on the amount of deformation. If the assembly groove 31 is a closed-bottom structure, it cannot provide redundant space for the downward deformation of the load cell 4. Therefore, the present invention provides a first through hole 33 in the assembly groove 31 to provide redundant space for the downward deformation of the load cell 4, ensuring that it can achieve the effect of weighing detection.

[0055] Example 3

[0056] In a third optional embodiment of the present invention, a technical solution is provided regarding the specific structural configuration of the liquid-holding tray 7, the stove body 8, and the burner assembly 9.

[0057] See Figure 1 and Figure 6As shown, in this embodiment, the gas stove with high-precision weighing function further includes a burner cap 6 and a liquid collection tray 7. The burner cap 6 is located at the top of the circular burner opening, and the liquid collection tray 7 is located between the burner cap 6 and the weighing sensor 4. The burner cap 6, also known as a flame distributor, serves as the combustion part of the gas stove of this invention, and this part has a high temperature. Specifically, the weighing sensor 4 is located at the bottom of the burner cap 6. By placing the liquid collection tray 7 between the burner cap 6 and the weighing sensor 4, heat insulation can be achieved, preventing the high-temperature heat from the burner cap 6 from affecting the detection effect of the weighing sensor 4 and ensuring its high detection accuracy.

[0058] See Figure 2 and Figure 6 As shown, in a preferred embodiment, a gap is provided between the bottom of the pot support 5 and the top of the panel 1. An annular protrusion 71 is provided on the outer periphery of the liquid-holding tray 7, and the annular protrusion 71 is disposed within the gap, with its bottom tightly against the top of the panel 1. Since the weighing principle of this invention involves the pot support 5 driving the sensor bracket 41 downwards to deform the weighing sensor 4, a predetermined gap must be provided between the bottom of the pot support 5 and the top of the panel 1 to ensure sufficient space for the pot support 5 to move downwards. Specifically, the annular protrusion 71 can be a protrusion structure formed by extending downwards or upwards from the outer periphery of the liquid-holding tray 7, and it has a certain width in the vertical direction. After the liquid-holding tray 7 is installed, the annular protrusion 71 is tightly against the top of the panel 1, thereby preventing liquid or other food on the panel 1 from entering the gas stove through this gap, thus acting as a seal. It is worth mentioning that after the liquid-holding tray 7 is installed, a predetermined distance is also provided between the top of the annular protrusion 71 and the pot support 5 to ensure sufficient space for the pot support 5 to move downwards.

[0059] See Figure 2 As shown, in another preferred embodiment, the top of the liquid collection tray 7 is provided with a downwardly recessed groove 72, which is located at the bottom of the circular burner opening and is used to collect objects that fall from the circular burner opening. Specifically, although the annular protrusion 71 can prevent liquids or other food on the panel 1 from entering the gas stove, it is difficult to avoid food from cooking utensils falling directly into the gas stove through the circular burner opening of the panel 1 and the opening 22 of the fixing bracket 2 during cooking. Therefore, the present invention provides a groove 72 on the liquid collection tray 7 to collect and hold liquids or other food that fall from cooking utensils, further preventing liquids or other food from entering the gas stove. More specifically, the liquid collection tray 7 can be detachably installed, making it convenient for users to periodically clean the food out of the groove 72; it can also be provided with a pipe or other drainage structure to drain the food out of the groove 72; the specific structural design is not limited in detail in this embodiment.

[0060] See Figure 2 and Figure 6 As shown, in another preferred embodiment, the top of the liquid-holding tray 7 is further provided with several protrusions 74 that protrude upward relative to the groove 72. Each protrusion 74 has a through hole 73 through which the sensor bracket 41 passes upward, allowing the pot rack 5 to be positioned on top of the sensor bracket 41. Specifically, since the liquid-holding tray 7 is positioned between the weighing sensor 4 and the burner cap 6, a second through hole 73 is provided on the liquid-holding tray 7 for the sensor bracket 41 to pass upward, ensuring that the pot rack 5 can be positioned on top of the sensor bracket 41. More specifically, since the groove 72 is used to hold spilled liquids or other food, to prevent such liquids or other food from falling into the gas stove through the second through hole 73, the present invention provides a protrusion 74 on the top of the liquid-holding tray 7, and positions the second through hole 73 on this protrusion 74, ensuring that liquids or other food cannot fall into the gas stove through the second through hole 73.

[0061] See Figure 1 and Figure 5 As shown, in another optional embodiment, the gas stove with high-precision weighing function further includes a stove body 8 and a burner assembly 9. The panel 1 is fixedly mounted on the top of the stove body 8, the burner assembly 9 is located inside the stove body 8, and the burner cap 6 is located on top of the burner assembly 9. The burner assembly 9 includes several injector tubes and other structures for introducing gas from external pipes and guiding the gas to the burner cap 6 for ignition and combustion, heating the cooking utensils on the pot rack 5 to achieve a cooking effect. More specifically, the liquid-holding tray 7 of the present invention may have an opening in the middle for the burner assembly 9 to pass through, thereby mounting it on the burner assembly 9.

[0062] In summary, when using the gas stove with high-precision weighing function of this invention, the cooking pot is placed on top of the pot rack 5. Since the bottom of the pot rack 5 is in direct contact with the sensor bracket 41, the cooking pot exerts a downward force on the pot rack 5 under gravity. The pot rack 5 exerts the same downward force on the sensor bracket 41, causing the sensor bracket 41 to press positively against the weighing sensor 4, thereby causing the weighing sensor 4 to deform. Ultimately, the weight of the cooking pot can be directly and in real time measured. Compared with the existing technology that places the weighing sensor inside the stove body or at the bottom of the stove body, this invention directly measures the weight of the cooking pot through the contact between the pot rack 5 and the sensor bracket 41. The structural design is simple and reasonable and can significantly improve the weighing measurement accuracy.

[0063] Furthermore, since the load cell 4 is fixedly mounted on the sensor mounting bracket 3 of the fixed support 2, and the fixed support 2 is fixedly mounted on the bottom side of the panel 1 through its assembly part 21, the fixed assembly of the load cell 3 can be achieved. In this structural design, the sensor mounting bracket 3 serves as a support structure for the load cell 4, and the assembly part 21 and the panel 1 are closely fitted and fixedly connected over a large area. Therefore, the load cell 4 and the panel 1 are combined to form an integrated structure, which can significantly improve the shock resistance of the fixed support 2 and the weighing module, resulting in good structural stability and preventing structural deformation even after long-term use. Moreover, even if the fixed support 2 deforms, the deformation of the load cell 4 is only related to the downward force exerted by the pot frame 5 on the sensor support 41, thus not affecting the detection value of the load cell 4, further improving the detection accuracy of the load cell 4.

[0064] Furthermore, since the gas stove provided by this invention has multiple circular burners, each with a corresponding fixed bracket 2 and a weighing module, the weight of the cooking utensils on each burner can be measured separately. Compared to a design where the weighing module is placed on the bottom shell of the stove, this invention can accurately measure the weight of each cooking utensil, rather than simply determining the total weight of all the utensils placed on the gas stove. Moreover, by combining the weighing sensor, fixed bracket 2, and panel 1 into an integrated structure, the weighing measurement function can be achieved even with the panel 1 serving as a fixed support structure. This allows the gas stove of this invention to be adapted for embedded applications, where the panel 1 is fixed to the stovetop, and the stove body 8 is partially embedded inside the stovetop. A design where the weighing module is placed on the bottom shell of the stove is not suitable for this application scenario.

[0065] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
