Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically a top-ventilated built-in induction cooker. Background Technology

[0002] Built-in induction cooktops are increasingly used in modern home and commercial kitchens due to their advantages such as space saving, aesthetic appeal, and high heating efficiency. Unlike traditional countertop induction cooktops, built-in induction cooktops typically have most or all of the cooktop body embedded in pre-drilled mounting holes in the countertop, creating a relatively flat and seamless surface that enhances the overall aesthetics and space utilization of the kitchen.

[0003] During the operation of an induction cooker, its core electronic components, such as IGBTs, rectifier bridges, resonant capacitors, and coils, generate a significant amount of heat due to the large current flowing through them. To ensure that these components operate stably within a suitable temperature range and to prevent performance degradation, damage, or even safety hazards caused by overheating, induction cookers are typically equipped with a cooling system, usually including a cooling fan and a designed cooling duct.

[0004] However, many existing built-in induction cookers have some inherent defects in their heat dissipation structure design, mainly in the following aspects:

[0005] 1. Heat dissipation into the cabinet leads to low heat dissipation efficiency: Most traditional built-in induction cookers are designed to dissipate the hot air generated during operation into the space below or behind the cooker, i.e., inside the cabinet. The inside of a cabinet is typically a relatively enclosed or poorly ventilated environment, lacking sufficient air convection. This causes the heat dissipated by the induction cooker to accumulate inside the cabinet, making it difficult to dissipate quickly and effectively to the outside environment. As the induction cooker continues to operate, the temperature inside the cabinet gradually rises, which in turn causes the temperature of the cooling air entering the cooker to rise as well, significantly reducing the efficiency of the heat dissipation system.

[0006] 2. Impact on the lifespan and stability of the induction cooker: Due to poor heat dissipation, the electronic components inside the induction cooker operate at high ambient temperatures for extended periods. High temperatures accelerate the aging process of these components, leading to issues such as semiconductor parameter drift, increased capacitor leakage current, and deterioration of insulation material performance, thus significantly shortening the overall lifespan of the induction cooker. Furthermore, sustained high temperatures can cause frequent activation of thermal protection mechanisms, unstable heating power, or even malfunctions and shutdowns, affecting user experience and the continuity of the cooking process.

[0007] 3. Potential damage to cabinets and stored items: The heat radiated from the induction cooker into the cabinets not only affects the cooker itself but also adversely impacts the cabinets and other items stored inside. For example, the cabinet panels may warp, crack, or release harmful gases due to prolonged exposure to heat; nearby food items and seasonings may also deteriorate or have their shelf life shortened due to the high temperature. Therefore, further improvements are necessary. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a top-ventilated embedded induction cooker with a simple structure, low manufacturing cost, and efficient and smooth heat dissipation, preventing heat accumulation inside the cabinet, thereby improving heat dissipation efficiency, extending the service life of the induction cooker, and improving the usage environment.

[0009] The purpose of this utility model is achieved in the following way: a top-ventilated embedded induction cooker, which includes an induction cooker body, a panel covering the top of the induction cooker body, the induction cooker body being installed on a kitchen countertop through the panel, the induction cooker body being embedded in a mounting hole opened in the kitchen countertop, the panel having a ventilation groove, the ventilation groove being in communication with the inside of the induction cooker body, the hot air generated by the induction cooker body when working being discharged upwards outside the panel through the ventilation groove.

[0010] An isolator is embedded in the ventilation slot; an isolation cover covers the ventilation slot on the panel and houses the isolator thereunder; the top of the isolation cover has several ventilation holes.

[0011] Furthermore: the isolator includes a rectangular top frame, with several isolating columns extending downward from the bottom of the top frame and connected to the base, forming a ventilation cavity between adjacent isolating columns.

[0012] Furthermore, the top frame extends outward to form a support platform, the outer contour of which is larger than the ventilation slot, so that the support platform covers the ventilation slot.

[0013] Furthermore, the sidewall of the isolator is recessed inward to provide a handle area.

[0014] Furthermore, the upper surface of the base is recessed to provide a receiving area.

[0015] Furthermore, the isolator is integrally injection molded from plastic material.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0017] 2. In this application, a ventilation slot is created on the top panel of the induction cooker body, and this ventilation slot is connected to the interior of the induction cooker body. When the induction cooker is working, the hot air generated inside can be directly exhausted upwards to the external environment of the panel through the ventilation slot, instead of being exhausted into the relatively enclosed and poorly ventilated cabinet interior as in traditional built-in induction cookers. This "top ventilation" design follows the physical law of the natural rise of hot air, greatly improving heat dissipation efficiency and effectively preventing heat accumulation inside the cabinet.

[0018] 3. Due to improved heat dissipation, the electronic components inside the induction cooker, such as IGBTs and coils, can operate stably at lower temperatures, thus significantly extending the overall lifespan of the induction cooker and improving its operational stability and reliability.

[0019] 4. An isolator is embedded in the ventilation slot, and an isolation cover is placed over the surface of the ventilation slot, housing both the isolator and the ventilation slot. This double protection structure effectively prevents food residue, soup, liquids, cleaning products, or other small foreign objects from falling into the interior of the induction cooker through the ventilation slot during daily use.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. A top-ventilated embedded induction cooker includes an induction cooker body 1, with a panel 2 covering the top of the body 1. The induction cooker body 1 is mounted on a kitchen countertop via the panel 2, and is embedded in mounting holes in the countertop. A ventilation groove 3 is provided on the panel 2, communicating with the interior of the induction cooker body 1. Hot air generated by the induction cooker body 1 during operation is discharged upwards outside the panel 2 through the ventilation groove 3. An isolator 4 is embedded within the ventilation groove 3. An isolation cover 5 covers the ventilation groove 3 on the panel 2 and houses the isolator 4 beneath it. A plurality of ventilation holes 51 are provided on the top of the isolation cover 5.

[0025] In this embodiment, when the induction cooker body 1 is working, the heat generated by the internal electronic components heats the surrounding air. Unlike traditional built-in induction cookers that exhaust hot air into the cabinet, this invention achieves heat dissipation through a ventilation slot 3 on the top panel 2 of the induction cooker body. This ventilation slot 3 is directly connected to the internal space of the induction cooker body 1, forming a main upward exhaust channel for hot air. The hot air inside the induction cooker is exhausted directly upwards through this ventilation slot 3, i.e., to the external space of the panel 2. At the same time, an isolator 4 is installed inside the ventilation slot 3, and an isolation cover 5 covers the outside of the ventilation slot 3. The isolation cover 5 houses the isolator 4 below it. During the upward exhaust process, the hot air first passes through the isolator 4, and then finally dissipates into the kitchen environment through several vents 51 on the top of the isolation cover 5. The isolator 4 and the isolation cover 5 with vents 51 work together to allow hot air to pass through while initially blocking foreign objects that may fall in from above.

[0026] The hot air is expelled directly upwards, following the natural convection pattern of rising hot air, preventing heat buildup inside the cabinet and significantly improving heat dissipation efficiency. This efficient heat dissipation effectively reduces the operating temperature of the induction cooker's internal components, thereby extending its lifespan and improving its stability and reliability during operation.

[0027] Meanwhile, the isolation device 4 and the isolation cover 5 with ventilation holes 51 provide basic protection for the ventilation slot 3, preventing larger foreign objects from falling directly into the induction cooker and ensuring the normal operation of the induction cooker.

[0028] In one embodiment, the isolator 4 includes a rectangular top frame 41. Several isolating posts 42 extend downwards from the bottom of the top frame 41 and connect to a base 47, forming a ventilation cavity 43 between adjacent isolating posts 42. These ventilation cavities 43 naturally form between adjacent isolating posts 42. These ventilation cavities 43 are the main channels for hot air to flow from the inside of the induction cooker body to the isolation cover 5. The isolating posts 42 themselves serve to physically block larger foreign objects. Simultaneously, the top frame 41 and the base 47 provide structural support for the isolating posts 42, allowing the isolator 4 to be stably installed within the ventilation slot 3. Compared to a simple mesh structure, the isolator 4, composed of a top frame, isolating posts, and a base, has a larger ventilation area and a more robust structure. Furthermore, the isolating posts 42 can more effectively block foreign objects of different directions and shapes. The presence of the ventilation cavities 43 makes the airflow channel more clearly defined, helping to guide the orderly discharge of hot air.

[0029] In one embodiment, the top frame 41 extends outward with a support 44, the outer contour of which is larger than the ventilation slot 3, such that the support 44 covers the ventilation slot 3. The outer contour of the support 44 extending outward from the top frame 41 is designed to be larger than the opening of the ventilation slot 3 on the panel 2. When the isolator 4 is installed, this support 44 rests on the surface of the panel 2 at the edge of the opening of the ventilation slot 3. The support 44 covers the periphery of the ventilation slot 3, that is, the joint area between the opening of the ventilation slot 3 and the panel 2.

[0030] The support 44 ensures that the isolator 4 can be accurately and stably placed in the predetermined position of the ventilation slot 3, preventing it from falling in or shaking inside the ventilation slot. The support 44 covers the edge of the opening of the ventilation slot 3, which can effectively prevent liquid or fine particles from seeping into the ventilation slot 3 from the gap between the isolator 4 and the panel 2.

[0031] In one embodiment, the isolator 4 has an inwardly recessed hand grip area 45 on its side wall. This recessed area provides a gripping point for the user's fingers. The user can easily remove the isolator 4 from the ventilation slot 3 using this hand grip area 45 to clean the isolator 4 itself, the inside of the ventilation slot 3, and the underside of the isolation cover 5. This makes the disassembly and installation of the isolator 4 more convenient and quick, facilitating daily cleaning and maintenance by the user.

[0032] In one embodiment, the upper surface of the base 47 is recessed to form a receiving area 46. If extremely fine dust, condensed oil, or a small amount of condensate droplets pass through the vent 51 of the isolation cover 5 and the ventilation cavity 43 at the top of the isolator 4, this receiving area 46 at the bottom can collect and contain these particles, preventing them from penetrating further into the core area of ​​the induction cooker body 1.

[0033] In one embodiment, the isolator 4 is integrally injection molded from plastic material. This is achieved through a one-piece injection molding process. This allows all parts of the isolator 4, such as the top frame, isolating pillars, and base, to be integrally molded in a single mold. One-piece injection molding is suitable for mass production and can effectively reduce manufacturing costs.

[0034] In summary, the core working principle of the top-ventilated embedded induction cooker disclosed in this case lies in constructing an efficient upward heat dissipation channel and setting multiple protective structures on this channel to ensure the safe, stable and long-term operation of the induction cooker.

[0035] The heat generated by the induction cooker body 1 during operation is guided upwards through a structure connecting its interior to the ventilation slots 3 on the top panel 2. The hot air is then exhausted into the kitchen environment outside the panel 2 through several vents 51 on the top of the isolation cover 5 covering the ventilation slots 3. This direct upward heat dissipation method avoids the problem of heat accumulation inside the cabinets inherent in traditional built-in induction cookers, significantly improving heat dissipation efficiency.

[0036] To protect the main body of the induction cooker, multiple layers of protection are also installed in this case:

[0037] Level 1 protection, isolation shield: Isolation shield 5 serves as the outermost layer of protection. Its top ventilation holes 51 ensure air circulation while effectively preventing large food residues, liquid splashes, and other foreign objects from directly entering the ventilation slot 3.

[0038] The second level of protection, the isolator: The isolator 4, installed in the ventilation slot 3 and located below the isolation cover 5, provides further protection. Its structure, consisting of a top frame 41, isolation columns 42 and a base 47, allows airflow through the ventilation cavity 43 between the isolation columns 42, while the isolation columns 42 themselves form a physical barrier to block smaller foreign objects that may pass through the vent holes 51 of the isolation cover 5.

[0039] The support platform 44 extending outward from the top frame 41 rests on the panel 2 at the outer edge of the ventilation slot 3, ensuring the isolator 4 is securely installed and sealing the gap between the isolator 4 and the edge of the ventilation slot 3 to prevent foreign objects from seeping in. Additionally, the recessed receiving area 46 on the upper surface of the isolator 4 base 47 can collect extremely fine particles or condensation that may penetrate the upper protective layer, serving as an extra protective measure.

[0040] Therefore, by changing the heat dissipation of the induction cooker from the traditional cabinet to upward, and by cleverly designing an isolator 4 and an isolation cover 5 system with multiple protective functions, this invention not only significantly improves the heat dissipation performance of the built-in induction cooker, extends its service life, and improves its working stability, but also effectively prevents foreign objects from entering the induction cooker, ensuring safety during use, and taking into account the user's convenience in cleaning and maintenance. Therefore, it can be widely promoted and used.
