Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, in particular to a cooking appliance with a pot recognition structure. Background Art

[0002] The multifunctional cooking pot can achieve multiple functions by placing different accessories. When the baking tray is placed on the main body of the cooking pot, the cooking pot should recognize and switch to the electric oven mode. There are two main current solutions. The first is that when the user places the pot, they select the function mode on the operation interface. This solution requires user participation in the operation, affecting the user experience. The second is to set a mechanical structure. When the baking tray is placed on the main body of the cooking pot, a signal can be generated through the physical contact between the baking tray and the switch component, enabling the control module to switch to the electric oven mode.

[0003] In the mechanical recognition structure, there is a common lever switch structure, but its structure is relatively complex, the assembly difficulty is high, and the production efficiency is low.

[0004] There is also a sliding rod switch structure adopted. For example, Chinese Patent CN2021204436265 discloses a cooking appliance with a pot recognition function, which adopts an identification structure combining a vertically sliding switch rod and a microswitch or an optoelectronic switch. Among them, the switch rod is vertically slidably arranged in the housing, and the microswitch or the optoelectronic switch is located directly below the switch rod. When the switch rod is pressed down by a preset trigger height, the lower end of the switch rod will push against the moving reed of the microswitch to make the moving contact and the static contact conduct, or the lower end of the switch rod will block the optoelectronic switch to trigger the optoelectronic signal. However, since the switch rod triggers the switch element in the forward direction, that is, the triggering action is directly related to the downward stroke of the switch rod. Due to the small contact spacing of the microswitch and the high triggering accuracy of the optoelectronic switch, when the downward pressure of the switch rod fluctuates, such as when the downward pressure of the switch rod is slightly smaller, it may not be able to complete the trigger, or when the downward pressure of the switch rod is too large, it will damage the switch element. Therefore, there are relatively high matching accuracy requirements for the installation environment of the pot, the downward stroke of the pot pressing against the switch rod, the installation position of the switch element, etc., resulting in a high assembly difficulty and high production cost. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a cooking appliance with a pot recognition structure, which adopts a switch structure that laterally triggers the switch element, with low required matching accuracy, which is beneficial to reducing the assembly difficulty and cost.

[0032] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] Refer to Figures 1 to 5 , the present invention discloses a cooking appliance with a cookware recognition structure, including a cookware 2 and a cooker 1. Among them, a top post 21 is provided at the bottom of the cookware 2, and the cooker 1 includes a housing 11, a switch element 12, a slide bar 13, an elastic member 14, a control panel assembly 15, and a heating element. The heating element is arranged in the housing 11. The slide bar 13 slides up and down in the housing 11 and corresponds to the position of the top post 21. The elastic member 14 is arranged between the housing 11 and the slide bar 13. The switch element 12 is horizontally installed in the housing 11 and is located on one side of the slide bar 13 in the horizontal direction. The control panel assembly 15 is arranged on the housing 11. The control panel assembly 15 is electrically connected to the switch element 12. A contact block 131 is arranged on the slide bar 13. When the slide bar 13 is pressed down by a preset trigger height, the contact block 131 laterally triggers the switch element 12.

[0036] It can be understood that the heating element can also be arranged in the cookware 2. At this time, a structure electrically connected to the heating element needs to be arranged in the cooker 1, so as to control the operation of the heating element by using the cooker 1.

[0037] In the above solution, the switching element 12 is arranged horizontally and located on one side of the sliding rod 13 in the horizontal direction, and a contact block 131 is provided on the sliding rod 13. When the cookware 2 is placed on the cooking appliance 1, the top column 21 presses down the sliding rod 13 downward, causing the sliding rod 13 to slide downward. The contact block 131 will slide downward together with the sliding rod 13. When the sliding rod 13 is pressed down to a preset trigger height, the contact block 131 can trigger the switching element 12 laterally. In this way, while ensuring that the switching element 12 can be triggered normally, the precision requirement for the amount of downward pressure on the sliding rod 13 is reduced, and further the requirements for the matching precision between the cookware 2 and the sliding rod 13, the relative position precision between the sliding rod 13 and the switching element 12, etc. are reduced. The overall required matching precision is low, which is beneficial to reducing the assembly difficulty and cost.

[0038] It can be understood that the cooking appliance can be a cooking pot, an induction cooker, a red-hot stove, a thermal stove, an electric ceramic stove, etc. When taking the cooking pot as an example for illustration, the target cookware can specifically be a frying pan, and a top column 21 is provided at the bottom of the frying pan, while there is no top column 21 at the bottom of the non-target cookware. The cooking appliance 1 can specifically be the main body of the cooking pot. In this way, when the frying pan is placed on the main body of the cooking pot, the frying pan triggers the switching element 12 through the contact block 131 on the sliding rod 13 to generate a signal, so as to identify that it is a frying pan, and thus can switch to the frying pan mode.

[0039] In addition, in other preferred embodiments, the opposite identification method can also be adopted. A groove can be provided at the bottom of the cookware 2, and the groove also corresponds to the position of the sliding rod 13. Still taking the cooking pot as an example, a groove is provided at the bottom of the frying pan, while there is no groove at the bottom of the non-target cookware. In this way, when the cookware cannot press the sliding rod 13 and the contact block 131 does not trigger the switching element 12, it is identified as a frying pan, and thus can switch to the frying pan mode. When the cookware triggers the switching element 12 through the contact block 131 on the sliding rod 13 to generate a signal, it is identified as not a frying pan, and at this time, other cooking modes are adopted.

[0040] Refer to Figures 4 to 6In this embodiment, the switch element 12 is preferably a micro switch. Based on the micro switch, it is further preferred that the contact block 131 has an inclined guide surface 1311 and a vertical contact surface 1312, and the inclined guide surface 1311 is connected to the bottom of the vertical contact surface 1312; specifically, the connection between the inclined guide surface 1311 and the vertical contact surface 1312 is transitioned through a rounded corner 1313, so that the triggering action is smoother. In this way, when the contact block 131 slides downward following the slide bar 13, the inclined guide surface 1311 first contacts the moving spring of the micro switch to play a guiding role, and then transitions to the vertical contact surface 1312. Since the vertical contact surface 1312 is arranged vertically, when the downward pressure of the slide bar 13 fluctuates, the vertical contact surface 1312 can be used to maintain the triggering of the micro switch, wherein the effective height of the vertical contact surface 1312 corresponds to the allowable fluctuation range of the downward pressure of the slide bar 13.

[0041] It is understandable that when the switch element 12 is a photoelectric switch, the resisting block 131 may only have a vertical contact surface 1312 without having an inclined guide surface 1311 .

[0042] See also Figures 1 to 5 In order to facilitate production and assembly, in this embodiment, the housing 11 includes a switch seat 111 and a bakelite seat 112, the switch element 12 is installed on the switch seat 111, the slide bar 13 is slidably arranged on the switch seat 111, and the elastic member 14 is arranged between the switch seat 111 and the slide bar 13. The switch seat 111 is used to install the switch element 12, the slide bar 13, and the elastic member 14, so that they can be integrated into a switch assembly first, and the switch seat 111 is detachably installed under the bakelite seat 112. The bakelite seat 112 is provided with a first hole 1121 and a receiving groove 1122, wherein the first hole 1121 is for the slide bar 13 to extend out, and the receiving groove 1122 is connected to the top of the first hole 1121, and the receiving groove 1122 is also open upward. The top column 21 can extend into the receiving groove 1122. During assembly, the integrated switch assembly is installed as a whole into the bakelite seat 112, and the slide bar 13 is extended into the receiving groove 1122 from the first hole 1121, and the upper end surface of the slide bar 13 is lower than the upper opening end surface of the receiving groove 1122. When the pot 2 is placed on the stove 1, the top column 21 extends into the receiving groove 1122 and presses the slide bar 13 downward, thereby allowing the pot 2 to press the slide bar 13; it is also preferred that the diameter of the lower end of the top column 21 is larger than the diameter of the first hole 1121, thereby avoiding excessive pressure caused by the top column 21 inserted into the first hole 1121 when the pot 2 is installed incorrectly, thereby avoiding excessive sliding of the abutment block 131 and thus detaching from the switch element 12.

[0043] In the above solution, the switch base 111 is used to install the switch element 12, the sliding rod 13, and the elastic member 14, so that they can be first integrated into a switch assembly and then integrally installed into the bakelite base 112, which is convenient for production and assembly, further reduces the assembly difficulty, and is also beneficial to simplifying the structure of the bakelite base 112.

[0044] Among them, a top post 21 is provided at the bottom of the cookware 2. Therefore, a receiving groove 1122 is provided in the bakelite base 112, and the sliding rod 13 is controlled not to protrude from the receiving groove 1122, so as to avoid accidental touch. When a groove is provided at the bottom of the cookware 2, it is preferable to cancel the receiving groove 1122 and make the sliding rod 13 expose outward from the first hole 1121, so that a non-target cookware can press against the sliding rod 13.

[0045] Refer to Figures 4 to 6 , specifically, the sliding rod 13 includes a first rod section 132, an intermediate boss 133, a second rod section 134, and an elastic bayonet 135; among them, the first rod section 132 is connected above the intermediate boss 133, the second rod section 134 is connected below the intermediate boss 133, the abutting block 131 is connected to the circumferential outer side of the intermediate boss 133, and an elastic bayonet 135 is provided at the lower end of the second rod section 134. Preferably, the first rod section 132, the intermediate boss 133, the second rod section 134, the abutting block 131, and the elastic bayonet 135 are integrally formed, so that the overall strength of the sliding rod 13 is high and the movement is stable; the upper end of the abutting block 131 can abut against the bakelite base 112 for limiting, so as to control the height dimension of the sliding rod 13 extending from the first hole 1121; the elastic member 14 is a spring and is sleeved on the second rod section 134, the upper end of the elastic member 14 abuts against the lower surface of the intermediate boss 133, and the lower end of the elastic member 14 abuts against the switch base 111. In this way, the elastic member 14 can provide a reset force for the sliding rod 13 to slide upward; a second hole 1111 is provided on the switch base 111, and the elastic bayonet 135 passes through the second hole 1111 from top to bottom, and the elastic bayonet 135 can abut against the lower surface of the second hole 1111 to prevent the sliding rod 13 from detaching from the switch base 111. In this way, when the switch element 12, the sliding rod 13, and the elastic member 14 are installed on the switch base 111 to be integrated into a switch assembly, the elastic bayonet 135 can be used to realize the pre-installation of the sliding rod 13 on the switch base 111.

[0046] Based on the specific structure of the sliding rod 13 described above, it can not only realize the function of triggering the switch element 12, but also the sliding rod 13 can realize the functions of stroke limiting and anti-detachment. The overall structure is simple and the assembly is convenient, achieving the double combination of function and cost control.

[0047] The technical means disclosed by the solution of the present utility model 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 for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
