Description

Technical Field

[0001] This invention relates to a cooktop, a control method, and an integrated cooktop, belonging to the technical field of kitchen appliances. Background Technology

[0002] During cooking, forgetting to turn off the stove and leaving it dry poses a serious safety hazard. Dry burning of the stove can easily cause accidents such as fires. The introduction of anti-dry burning function can improve the safety of gas stove use.

[0003] In one existing technology concerning cooktops, a weighing module is incorporated to weigh the pots on the pot rack, thereby determining whether the cooktop is in a pot-supported state or an empty-burning state, to prevent fires caused by empty-burning. However, the mechanism for determining the cooktop's status through weighing is rather cumbersome, and the weighing module itself has a complex structure with numerous components. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stove, a control method and an integrated stove that can avoid the occurrence of dry burning, and the judgment mechanism is simple and the structure is easy to construct.

[0005] The present invention is achieved through the following technical solution.

[0006] A stove includes a load-bearing component, a burner mounted on the load-bearing component, an elastic element, and a sensing component. The load-bearing component has multiple positioning grooves along its circumferential edge for supporting legs of a pot rack. The load-bearing component can sink under pressure, and the elastic element acts on the load-bearing component to lift it back to its original position. The sensing component senses whether the sinking stroke of the load-bearing component exceeds a threshold. If the sinking stroke does not exceed the threshold, the burner stops burning or reduces its heat; if the sinking stroke exceeds the threshold, the burner maintains combustion.

[0007] As a further improvement of the present invention, the sensing component includes a sensing contact and a sensing probe; the sensing contact is positioned on the load-bearing component, and the position of the sensing probe is fixed; if the sinking stroke of the load-bearing component does not exceed a threshold, the sensing contact and the sensing probe are in a separated state; if the sinking stroke exceeds the threshold, the sensing contact and the sensing probe remain in contact.

[0008] As a further improvement of the present invention, the load-bearing component includes a water receiving tray for supporting the burner and a positioning ring surrounding the water receiving tray; the positioning groove is formed by the top surface of the positioning ring being recessed inward, and a slot is formed on the top surface of the positioning ring.

[0009] As a further improvement of the present invention, an installation ring is provided on the stove, and an installation seat is provided on the installation ring; the positioning ring covers the installation ring and the installation seat, the sensing contact is provided on the groove wall of the positioning groove, and the sensing probe is provided on the installation seat.

[0010] As a further improvement of the present invention, the positioning groove has an opening formed on the outer ring surface of the positioning ring, such that the groove wall of the positioning groove includes two side groove walls located on both sides of the opening and an inner groove wall opposite to the opening.

[0011] As a further improvement of the present invention, each of the positioning slots is provided with two sensing contacts and two sensing probes; the two sensing contacts are respectively disposed on the two side walls of the positioning slot.

[0012] As a further improvement of the present invention, the two side groove walls and the inner groove wall are inclined from top to bottom, so that the positioning groove gradually narrows from the top groove opening to the bottom groove bottom, and a tapering structure for positioning the support leg is formed at the bottom of the groove.

[0013] As a further improvement of the present invention, the bottom end of the elastic element is supported on the mounting ring, and the top end is supported on the bottom of the positioning groove.

[0014] A control method, comprising the steps of:

[0015] Step S1: Burner ignition and combustion:

[0016] Step S2: Determine whether the sinking stroke of the weighing component exceeds the threshold using the sensing component;

[0017] Step S3: If the descent stroke does not exceed the threshold, the burner stops burning or reduces the firepower; if the descent stroke exceeds the threshold, the burner remains in combustion mode.

[0018] As a further improvement of the present invention, in step S3, if the descent stroke does not exceed the threshold, the burner reduces the firepower; after a certain delay, the sensing component determines again whether the sinking stroke of the weighing component exceeds the threshold. If the descent stroke does not exceed the threshold, the burner stops burning; if the sinking stroke exceeds the threshold, the burner continues to burn.

[0019] An integrated cooktop, comprising the cooktop itself.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting the sinking stroke of the load-bearing components and the sensing components, it is possible to determine whether the stove is in the pot-supporting state or the empty-burning state, and then stop the combustion / reduce the firepower or maintain the combustion state, thereby avoiding the safety hazards caused by the stove being in the empty-burning state;

[0022] 2. There is no need to set up a weighing component to monitor the weight and then determine whether it is dry burning. It is not only simpler in terms of judgment mechanism, but also simpler in terms of structure. The load-bearing component not only works with the sensing component to determine whether the stove is in the pot-holding state or the dry burning state, but can also locate the support legs of the pot rack. It has a good degree of integration in terms of function.

[0023] 3. Since each positioning slot is equipped with a sensing component, the cookware can be placed at an angle based on whether there are differences in the sensing of each sensing component. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0037] Implementation Case 1:

[0038] A type of stove, reference Figures 1-9 The cooktop includes a load-bearing component 1, a burner 2, an elastic element 3, and a sensing component. The load-bearing component 1 serves as the supporting structure of the cooktop. The burner 2 is mounted on the load-bearing component 1. Multiple positioning grooves 11 are circumferentially arranged along the edge of the load-bearing component 1. The number and arrangement of the positioning grooves 11 match the legs 61 of the pot rack 6, supporting the legs 61 and allowing the pot rack 6 to be precisely positioned on the cooktop. The load-bearing component 1 can sink under pressure, and the sinking stroke corresponds to the weight of the pot rack 6. The elastic element 3 acts on the load-bearing component 1, providing an upward elastic force to lift and reset the load-bearing component 1. A threshold is set for the sinking stroke of the load-bearing component 1. When the sinking stroke exceeds the threshold, it is determined that the pot rack 6 is on the load-bearing component 1, indicating that the cooktop is in a pot-supported state. When the sinking stroke does not exceed the threshold, it is determined that the pot rack 6 is not on the load-bearing component 1, indicating that the cooktop is in a dry-burning state. The sensing component is used to sense whether the descent of the load-bearing component 1 exceeds a threshold. If the descent stroke does not exceed the threshold, the burner 2 stops burning or reduces the firepower. If the descent stroke exceeds the threshold, the burner 2 continues to burn.

[0039] In this embodiment, by setting the sinking stroke of the load-bearing component 1 and the sensing component, it is possible to determine whether the stove is in the pot-supporting state or the empty-burning state, and then stop combustion / reduce the firepower or maintain the combustion state, thereby avoiding the safety hazards caused by the stove in the empty-burning state. In addition, the stove in this embodiment does not need to set up a weighing component to monitor the weight and then determine whether it is dry-burning, which is not only simpler in judgment mechanism, but also simpler in structural composition. The load-bearing component 1 not only works with the sensing component to determine whether the stove is in the pot-supporting state or the empty-burning state, but also can position the support leg 61 of the pot rack 6, which has a good degree of integration in terms of function.

[0040] In this embodiment, the sensing component includes a sensing contact 41 and a sensing probe 42. The sensing contact 41 is positioned on the load-bearing component 1, and the sensing probe 42 is fixed in position. When the load-bearing component 1 is unloaded, i.e., when no pot is placed on the pot rack 6, the sensing contact 41 is located above the sensing probe 42. As the load-bearing component 1 gradually sinks, the distance between the sensing contact 41 and the sensing probe 42 gradually decreases. When the sinking stroke of the load-bearing component 1 reaches a threshold, the sensing contact 41 and the sensing probe 42 come into contact. This ensures that if the sinking stroke of the load-bearing component 1 does not exceed the threshold, the sensing contact 41 and the sensing probe 42 are in a separated state; if the sinking stroke exceeds the threshold, the sensing contact 41 and the sensing probe 42 remain in contact.

[0041] In this embodiment, the weighing assembly includes a water collection tray 12 and a positioning ring 13. The water collection tray 12 supports the burner 2 and its function is to collect condensate generated during cooking or water left over from cleaning the burner 2, preventing water droplets from splashing or flowing into the equipment and helping to keep the environment around the burner 2 dry. The positioning ring 13 surrounds the water collection tray 12, and a positioning groove 11 is formed by the inward indentation of the top surface of the positioning ring 13, with a slot formed on the top surface of the positioning ring 13.

[0042] In this embodiment, a mounting ring 51 is provided on the stove s1, and a mounting base 52 is provided on the mounting ring 51. The size of the mounting ring 51 matches that of the positioning ring 13, and the mounting ring 51 is set on the stove s1. The positioning ring 13 covers the mounting ring 51 and the mounting base 52. The sensing contact 41 is set on the groove wall of the positioning groove 11, so that the sensing contact is positioned on the weighing component. The sensing probe 42 is set on the mounting base 52, so that the position of the sensing probe 42 is fixed, thereby causing the load-bearing component 1 to sink under pressure. When the sinking stroke reaches the threshold, the sensing contact 41 and the sensing probe 42 make contact.

[0043] In this embodiment, the positioning groove 11 has an opening on the outer surface of the positioning ring 13, such that the groove wall of the positioning groove 11 includes two side groove walls 111 located on both sides of the opening and an inner groove wall 112 opposite to the opening. The opening of the positioning groove 11 on the outer surface of the positioning ring 13 makes the positioning groove 11 an externally open groove structure, which makes it more convenient to position the support legs 61 of the pot holder 6.

[0044] In this embodiment, each positioning slot 11 is equipped with a mounting base 52, two sensing contacts 41, and two sensing probes 42. The two sensing contacts 41 are respectively located on the two side walls 111 of the positioning slot 11. Each positioning slot 11 is equipped with a sensing component, making the judgment of the sinking stroke of the load-bearing component 1 more accurate and avoiding control errors. It should be noted that if the pot on the pot rack 6 is placed at an angle, it will cause the center of gravity of the pot rack 6 to shift, resulting in a deviation in the weight of each support leg 61 supporting the positioning slot 11. In other words, some sensing components may be activated while others are not, thus providing a judgment that the pot is placed at an angle. In addition, the sensing contacts 41 and corresponding sensing probes 42 are provided on the two side walls 111 of each positioning slot 11 for sensing, which can improve the sensing accuracy of each positioning slot 11 and further improve the accuracy of judging the pot-sitting state or the empty-burning state.

[0045] In this embodiment, the two side walls 111 and the inner wall 112 are inclined from top to bottom, so that the positioning groove 11 gradually narrows from the top opening to the bottom bottom 113, and a tapering structure for the positioning support 61 is formed at the bottom 113. This allows for more precise positioning of the pot holder 6's support 61 when placing it, preventing sensing deviations in the sensing components due to improper placement of the pot holder 6's support 61.

[0046] In this embodiment, the bottom end of the elastic element 3 is supported on the mounting ring 51, and the top end is supported on the bottom 113 of the positioning groove 11. The elastic element can be set as a compression spring. It should be noted that since the elastic element 3 is positioned corresponding to the bottom 113 of the positioning groove 11, the precise positioning of the support leg 61 by the constriction structure can prevent the elastic element 3 from failing due to improper placement of the pot holder 6, and the sensing component from being damaged beyond its measurement range.

[0047] In this embodiment, an electromagnetic coil module 53 is set at the bottom of the mounting ring 51. The electrode needle 21 and the thermocouple 22 are fixedly and detachably mounted on the burner 2, with the length protruding from the bottom surface of the burner 2. An electromagnetic power supply receiver 211 is set at the end of the electrode needle 21, which can be used as the output end of electromagnetic wireless power supply to provide power to the electrode needle 21. At the same time, the thermocouple 22 is detachable, with a magnetic contact end 221 at the lower end, realizing the detachable setting.

[0048] Implementation Case 2:

[0049] A control method, based on the stove in Implementation Case 1, and combined with Figures 1-9 The steps include:

[0050] Step S1: Ignition and combustion of burner 2:

[0051] Step S2: Determine whether the sinking stroke of the weighing component exceeds the threshold using the sensing component;

[0052] Step S3: If the descent stroke does not exceed the threshold, the burner 2 stops burning or reduces the firepower; if the descent stroke exceeds the threshold, the burner 2 remains in combustion state.

[0053] More specifically, in step S3: if the descent stroke does not exceed the threshold, the burner 2 reduces the firepower; after a certain delay, the sensor component is used again to determine whether the sinking stroke of the weighing component exceeds the threshold. If the descent stroke does not exceed the threshold, the burner 2 stops burning; if the sinking stroke exceeds the threshold, the burner 2 remains in the burning state.

[0054] In this implementation example, the delay time in step S3 can be set to 1 minute, or other values ​​can be set according to the user's application requirements.

[0055] The control method in this implementation case has a delay time set between step S1 and step S2, which is usually set to 20s, but other values ​​can also be set according to the user's application requirements.

[0056] Implementation Case 3:

[0057] An integrated stove, as shown in the reference Figure 10 This includes a stove s4, as shown in Implementation Case 1.

[0058] In this implementation case, the integrated stove includes a host computer s2 and a slave computer s3. The host computer s2 is located above the stove s1, and the slave computer s3 is located below the stove s1. The host computer s2 is set as a fume hood, and the slave computer s3 can be configured with a disinfection cabinet, a steam oven, a dishwasher, etc.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
