DETAILED DESCRIPTION
[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0033] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0034] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] The existing kitchen appliances 110, whether they are split stoves or hood and stove systems 100, include a stove 110 part and a hood part. The hood head is generally located above the stove 110, and a lighting lamp 140 is generally installed on the hood and at the bottom of the head storage table, aiming at the top of the burner. Due to aerodynamic factors, as well as the working principle and position design of the hood head, when the stove 110 is turned on, heat is generated from the burner of the stove 110 and rises with the hot air or smoke.
[0037] Under normal circumstances, heat is absorbed by the pot, and a small amount of heat rises with the smoke generated by the pot and is discharged to the outside through the hood head. However, when the pot is removed, a large amount of heat generated by the stove 110 will rise directly to the vicinity of the hood head without being absorbed, which will cause the temperature near the hood head to rise sharply. Therefore, when the stove 110 is turned on high, if the pot is removed, the temperature of the hood part will rise rapidly, and because the lighting lamp 140 is installed at the bottom of the head storage table, close to the top of the burner, it will also be affected by the heat, causing the temperature near it to rise. This temperature increase may cause the material of the lighting lamp 140 to lose its original performance, resulting in a significant decrease in the reliability of the lighting lamp 140, and even causing safety hazards. At the same time, for the paint on the head storage table, the high temperature puts it at risk of being burned, affecting the aesthetics and corrosion resistance.
[0038] The inventor has found that the stove 110 is currently provided with a pot detection probe, which can detect whether the pot is currently placed on the stove 110. However, the pot detection probe uses a contact sensing method with the bottom of the pot for sensing. In actual operation, when the user performs a pan-frying operation, the pot will be away from the sensing component of the above technical solution. At this time, the above device will also close the gas supply valve of the stove, resulting in insufficient firepower when frying.
[0039] Therefore, the utility model proposes a range hood system 100 with a pot detection function, which solves the safety hazard of overheating of the range hood and surrounding components caused by the removal of pots in the prior art, and at the same time optimizes the intelligence and flexibility of fire control during the cooking process.
[0040] Please refer to Figure 1The present embodiment provides a range hood and stove system 100 with a pot detection function, which includes a range hood and a stove 110. The stove 110 is located below the range hood. A stove head 130, a light emitter 200, a light sensor 300 and a lens 400 are provided on the stove 110. The light emitter 200 and the light sensor 300 are arranged at intervals and located above the stove head 130. The lens 400 is arranged corresponding to the position of the stove head 130. The light emitter 200 emits light, and the light is reflected by the lens 400 to the light sensor 300, and the light sensor 300 senses the light.
[0041] It is understandable that by setting the light emitter 200, the light sensor 300 and the lens 400, the light emitted by the emitter is reflected by the lens 400 to the light sensor 300; the light sensor 300 detects whether there is a pot on the stove head 130 by whether it can sense light. Different from the traditional contact sensing method, the smoke stove system 100 configured in this way realizes the pot detection function through a non-contact detection method; even in cooking operations such as flipping the pot, the pot state can be accurately identified, avoiding improper fire adjustment due to misjudgment, thereby ensuring that sufficient fire can be maintained during the cooking process, especially when it is necessary to stir-fry vigorously, improving cooking efficiency and food taste, meeting the needs of professional chefs and home cooking, optimizing the user experience, and improving safety. At the same time, this non-contact sensing method reduces the mechanical wear between the stove head 130 and the pot, reduces maintenance costs, and makes the entire smoke stove system 100 more stable and reliable, and can still maintain high performance operation under long-term use.
[0042] Please refer to Figure 1 In this embodiment, the range hood system 100 includes a range cooker 110 .
[0043] In this embodiment, the range hood system 100 includes a stove 110 and a machine top 120 extending along the upper direction of the stove 110, a lighting lamp 140 is installed on the machine top 120, and a range hood and other structures can be installed in the machine top 120; a stove head 130 is installed on the stove 110, and the stove head 130 is connected to an air supply pipeline; a pot support 131 is installed on the stove head 130, and the pot support 131 is used to support the pot; a rotary switch 150 is also installed on the stove 110, and rotating the rotary switch 150 can be used to adjust and control the firepower of the stove head 130.
[0044] The stove head 130 is arranged opposite to the lighting lamp 140 .
[0045] Please refer to Figure 6In this embodiment, the smoke stove system 100 also includes an electric control valve 800 and a controller 700; wherein the electric control valve 800 is connected to the gas supply pipeline of the stove head 130, and the electric control valve 800 can reduce the gas supply of the stove head 130 and thus reduce the firepower of the stove head 130; the controller 700 is electrically connected to the light emitter 200, the light sensor 300, the contact switch 500 and the driving member 600.
[0046] The output end of the controller 700 is electrically connected to the light emitter 200 , the contact switch 500 and the driver 600 ; the input end of the controller 700 is electrically connected to the light sensor 300 , and the light sensor 300 transmits a signal to the controller 700 when sensing light.
[0047] Please refer to Figure 1 In this embodiment, the cooker 110 is provided with a light emitter 200, a light sensor 300 and a lens 400. Specifically, the lens 400 is installed on the cooker 110 relative to the cooker head 130; the light emitter 200 and the light sensor 300 are located above the cooker head 130 and installed on the top 120, the light emitter 200 and the light sensor 300 are located on both sides of the illuminating lamp 140 and are symmetrically arranged relative to both sides of the cooker head 130, and the light emitter 200 and the light sensor 300 are arranged toward the lens 400.
[0048] The light emitter 200 may be a laser emitter.
[0049] Understandably, please refer to Figure 5 , the light emitter 200 emits light, and the light is reflected by the lens 400 to the light sensor 300, and the light sensor 300 can sense the light. When there is a pot on the stove 130, the pot blocks the light emission path, and the light sensor 300 cannot sense the light. At this time, the controller 700 will not control the fire of the stove 130 through the electric control valve 800. When there is no pot on the stove 130, the light is reflected by the lens 400 to the light sensor 300, and the light sensor 300 senses the light. The controller 700 controls the fire of the stove 130 through the electric control valve 800, and adjusts the electric control valve 800 to reduce the gas supply, which effectively prevents energy waste, reduces heat damage to the range hood and surrounding components, and prolongs the service life of the equipment. This setting realizes a non-contact pot presence detection function, and can accurately identify the pot status even in cooking operations such as flipping the pot, avoiding improper fire adjustment due to misjudgment, and significantly improving the safety of use.
[0050] Please refer to Figure 2In order to enable the controller 700 to sense whether the cooker 110 is in working state, in this embodiment, a contact switch 500 and at least one rotary switch 150 are further provided on the cooker 110. A sensing protrusion 151 is provided on the side wall of the rotary switch 150. The contact switch 500 is provided corresponding to the sensing protrusion 151.
[0051] In this embodiment, please refer to Figure 2 , two sets of rotary switches 150 and a stove head 130 are arranged on the stove 110. A fixing block 510 is arranged between the two rotary switches 150, and a sensing protrusion 151 is arranged on the side walls of the two rotary switches 150 and the sensing protrusion 151 is arranged toward the fixing block 510; the contact switch 500 is arranged on the side wall of the fixing block 510 and is arranged opposite to the position of the sensing protrusion 151.
[0052] Of course, in other optional embodiments, three or four groups of rotary switches 150 and stove heads 130 may also be provided on the stove 110 .
[0053] It is understandable that, during operation, when the user rotates the rotary switch 150, the rotary switch 150 rotates, causing the sensing protrusion to no longer be in contact with the contact switch 500, and the sensing protrusion 151 leaves the contact switch 500, thereby causing the switching quantity of the contact switch 500 to change. After the controller 700 receives the signal that the switching quantity of the contact switch 500 has changed, it controls the driving component 600 and the light emitter 200 to work simultaneously.
[0054] In some embodiments, a set of rotary switches 150 and stove heads 130 may be further provided on the stove 110. A sensing protrusion 151 is provided on the side wall of the rotary switch 150, and a contact switch 500 is provided at a position opposite to the sensing protrusion 151.
[0055] In some embodiments, the lens 400 is disposed directly opposite to the position of the cooker 110 , and the lens 400 is disposed horizontally so that the lens 400 can reflect the light emitted by the light emitter 200 to the light sensor 300 .
[0056] In some embodiments, in order to reduce the possibility of the mirror surface of the lens 400 being contaminated, the lens 400 is configured to be slidable. Figure 3 In this embodiment, a driving member 600 is arranged inside the cooker 110, and the output of the driving member 600 is connected to one end of a sliding block 630 through a transmission rod 620; at the same time, a slide groove 111 is arranged inside the cooker 110 relative to the position of the lens 400, and a sliding block 630 is arranged in the slide groove 111, and the lens 400 is arranged above the sliding block 630. The slide groove 111 is provided with an opening 1111, and the light emitter 200 and the light sensor 300 are arranged toward the opening 1111.
[0057] It is worth mentioning that the slide groove 111 is arranged inside the stove 110 , and the bottom of the slide groove 111 is arranged horizontally so that the sliding block 630 can slide horizontally along the slide groove 111 .
[0058] The driving member 600 may be a stepping motor or the like.
[0059] The opening 1111 of the slide groove 111 may be provided with a structure such as transparent glass.
[0060] Optionally, see Figure 3 In order to facilitate the reset of the sliding block 630 and avoid the collision between the sliding block 630 and the end surface of the slide slot 111, an elastic member 640 is arranged on the side of the slide slot 111 away from the driving member 600. The elastic member 640 may be a spring, an elastic sheet or the like.
[0061] In this embodiment, please refer to Figure 3 , two sets of rotary switches 150 and stove heads 130 are arranged on the stove 110. A driving member 600 and two slide grooves 111 and a sliding block 630 respectively arranged corresponding to the stove heads 130 can be arranged in the stove 110. Specifically, the two slide grooves 111 are respectively arranged relative to the two stove heads 130, the sliding block 630 is arranged in the slide groove 111, and the lens 400 is arranged on the sliding block 630; the output end of the driving member 600 is connected to the driving block 610 in a transmission manner, and the two sliding blocks 630 are respectively abutted against one end of the driving block 610 through the transmission rod 620, and the other end of the driving block 610 abuts against the elastic member 640.
[0062] It is understandable that the output end of the driving member 600 drives the driving block 610 to rotate, and the driving block 610 stops after rotating 90°, and the arc-surface outer walls on both sides of the driving block 610 respectively drive the two transmission rods 620, and the two transmission rods 620 respectively drive the two sliding blocks 630 to slide in their respective slide grooves 111, and transport the lenses 400 of the two sliding blocks 630 to the opening 1111. After use, the driving member 600 drives the driving block 610 to rotate 90°, and the two sliding blocks 630 are reset under the action of the elastic member 640.
[0063] Please refer to Figure 4 , the driving block 610 is an elliptical block.
[0064] Of course, in other embodiments, when three sets of rotary switches 150 and stove heads 130 are provided on the stove 110, the driving block 610 can be a triangular block with curved corners. When four sets of rotary switches 150 and stove heads 130 are provided on the stove 110, the driving block 610 can be a rectangular block with curved corners.
[0065] Of course, in other embodiments, a set of rotary switches 150 and a stove head 130 are provided on the stove 110; a driving member 600, a slide groove 111 and a sliding block 630 are provided in the stove 110. It can be understood that the output end of the driving member 600 drives the sliding block 630 to slide in the slide groove 111 through the transmission rod 620, and transports the lens 400 of the sliding block 630 to the opening 1111.
[0066] Please refer to Figure 1 and Figure 5 In this embodiment, the working principle of the smoke and stove system 100 with pot detection function is:
[0067] During operation, when the user turns the rotary switch 150, the stove head 130 ignites; the rotation of the rotary switch 150 causes the sensing protrusion to no longer be in contact with the contact switch 500, and the sensing protrusion 151 leaves the contact switch 500, thereby causing the switching quantity of the contact switch 500 to change. After the controller 700 receives the signal that the switching quantity of the contact switch 500 has changed, it controls the driving component 600 and the light emitter 200 to work simultaneously.
[0068] The driving member 600 works, and the output end of the driving member 600 drives the driving block 610 to rotate. The driving block 610 stops after rotating 90°. The arc-surface outer walls on both sides of the driving block 610 respectively drive the two transmission rods 620. The two transmission rods 620 respectively drive the two sliding blocks 630 to slide in their respective sliding grooves 111 and transport the lenses 400 of the two sliding blocks 630 to the opening 1111.
[0069] The light emitter 200 works and emits light, which is reflected by the lens 400 to the light sensor 300 .
[0070] When there is a pot on the stove 130, the pot blocks the emission path of the light, and the light sensor 300 cannot sense the light. At this time, the controller 700 will not control the fire of the stove 130 through the electric control valve 800. This ensures that during the cooking process, especially when strong stir-frying is required, sufficient firepower can be maintained, which improves cooking efficiency and food taste, and meets the needs of professional chefs and home cooks.
[0071] When there is no pot on the stove top 130, the light is reflected by the lens 400 to the light sensor 300. The light sensor 300 senses the light, which means that the pot has not only left the stove top 130 but also left above the stove top 130. The controller 700 controls the fire of the stove top 130 through the electric control valve 800, and adjusts the electric control valve 800 to reduce the gas supply, which effectively prevents energy waste, reduces heat damage to the range hood and surrounding components, and extends the service life of the equipment.
[0072] After the cookware leaves the stove head 130 , the controller 700 drives the driving member 600 to drive the driving block 610 to rotate another 90°, and the two sliding blocks 630 are reset under the action of the elastic member 640 .
[0073] In summary, the smoke and stove system 100 proposed in the utility model has a pot detection function, which solves the safety hazard of overheating of the range hood and surrounding components caused by the removal of the pot in the prior art, and optimizes the intelligence and flexibility of fire control during cooking; through intelligent and refined design, it not only improves the safety and practicality of kitchen appliances, but also promotes the effective use of energy, providing users with a more convenient and efficient cooking experience. It has the following beneficial effects:
[0074] 1. Intelligent detection and improved safety: Through the integrated lens 400, light emitter 200 and light sensor 300, non-contact detection with the cookware is achieved. The status of the cookware can be accurately identified even during cooking operations such as flipping the pan, avoiding improper fire adjustment due to misjudgment and significantly improving safety of use.
[0075] 2. Precise control, energy saving and high efficiency: When the pot is moved away from the stove 130, the light sensor 300 can instantly sense and automatically adjust the electric control valve 800 through the controller 700 to reduce the gas supply of the gas supply pipeline of the stove 130, effectively preventing energy waste and reducing heat damage to the range hood and surrounding components on the top 120 of the machine, thereby extending the service life of the equipment.
[0076] 3. Optimize the experience and maintain the firepower: Different from the traditional contact sensing method, the utility model adopts a non-contact detection method to ensure that sufficient firepower can be maintained during the cooking process, especially when vigorous stir-frying is required, thereby improving cooking efficiency and food taste, and meeting the needs of professional chefs and home cooks.
[0077] 4. Design innovation and integrated optimization: The slidable setting of the lens 400 enables flexible adjustment of the light path, and the design integrates the detection function inside the stove 110, while maintaining the simplicity and beauty of the appearance of the stove 110, which meets the aesthetic and space requirements of modern kitchens. At the same time, the lens 400 can be slid and retracted, reducing the possibility of the mirror surface being contaminated.
[0078] 5. Reduce wear and tear and enhance durability: The non-contact induction method reduces mechanical wear and tear, lowers maintenance costs, and makes the entire stove 110 system more stable and reliable, and can still maintain high performance under long-term use.
