Description

Technical Field

[0001] This invention mainly relates to the field of kitchenware, specifically an environmentally friendly heat conduction baking device based on a gas stove and its usage method. Background Technology

[0002] With economic development and improved living standards, gas stoves are now used in every household. However, existing gas stoves are limited in function and cannot perform grilling, braising, or baking. To obtain these functions, one must purchase additional appliances such as baking ovens, microwave ovens, and barbecue charcoal.

[0003] Among existing products, some offer simple grilling capabilities using gas stoves: one type is the infrared grill, which also uses gas, but instead of the standard gas stove port, it employs a different technological approach, a dedicated device separate from household gas stoves. Although it uses dense honeycomb holes to disperse the open flame, making it appear flameless to the naked eye, it still involves direct heat radiation from the burning gas onto the food. Not only is its function limited to grilling, but it also requires purchasing a separate gas stove, and because it still involves direct contact between the gas and the food, it is neither environmentally friendly nor healthy. This hinders product adoption and the resolution of substantial problems. It is well known that open flames from gas contain substances such as carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide, and hydrocarbons. Furthermore, for safety and to facilitate the detection of gas leaks, gas companies sometimes add hydrogen sulfide and methanethiol, commonly known as "odorants," to the gas. It's easy to imagine how dangerous this method of cooking food directly with an open flame is, and how many hidden dangers it poses. One method involves using an open flame directly, with only a simple mesh partition in between, yet the open flame still directly contacts the food. Another method utilizes the offset of the gas flame source, employing the principle of heat convection to create a heat source pipe that directs the heat source to one side for grilling. However, this method has extremely low thermal efficiency, significant heat loss, and its technical approach is flawed. Although the product appears to avoid contact with an open flame, it overlooks a fundamental and fatal problem: the exhaust gas produced by the gas also travels through the heat source pipe along with the heat, coming into contact with the food. Therefore, it is not only directionally incorrect but also fails to solve the fundamental problem.

[0004] China is a culinary superpower with a cooking history spanning thousands of years, leaving behind countless culinary techniques. However, due to limitations in product technology and processes, as well as the reforms brought about by urbanization, people have become accustomed to the simple use of gas stoves in urban life, gradually forgetting and abandoning many ways of cooking delicious food. Therefore, there is an urgent need for a brand-new, innovative product to fill this gap, making outstanding and substantial changes, and significantly improving the way people cook food without changing the gas stove itself. This would allow people to use their existing gas stoves at home to make all kinds of delicious food, easily performing grilling, braising, baking, and many other food preparation methods. Summary of the Invention

[0005] To address the above shortcomings, this invention creatively designs an environmentally friendly heat conduction baking device based on a gas stove and its usage method. It mainly consists of a baking base, a heat storage and conduction plate, a grill rack, and a top cover. This solves the problems of limited functionality and environmental friendliness of existing gas stove-based cooking utensils. It not only allows for flameless grilling but also braising, baking, and roasting, specifically for dishes such as roasted lamb skewers, roasted meat, braised rice, braised meat, roasted chicken, roasted duck, roasted fish, roasted egg tarts, roasted cakes, roasted sweet potatoes, baked flatbreads, dry-roasted peanuts, and roasted coffee beans. Its practical and diverse functions demonstrate outstanding substantive features and significant advancements, and it is fundamentally different from existing products, making it a pioneering product in its category.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An environmentally friendly heat conduction baking device based on a gas stove mainly consists of a baking base, a heat storage and heat conduction plate, an oil receiving tray, a grill rack, a baking plate, a surrounding enclosure, and a top cover. The baking base and the heat storage and heat conduction plate are combined together. The edge of the baking base is provided with several slots and shaft holes for placing the grill rack or baking plate. The baking base is used based on the gas stove, and its size is larger than the burner head and rack of the gas stove. The heat storage and heat conduction plate combined with the baking base is made of a heat-conducting refractory material with a thickness of no more than 3 cm, serving to store heat, conduct heat, and radiate heat, obtaining a heat source without open flame. The baking plate has a support edge on at least one side for attaching food. Two types of drip trays are provided: one around the perimeter of the grilling base, and the other in the center, spaced apart. The drip trays rest on the grilling base and the heat-conducting plate, while the grill rack or baking plate rests on the drip trays. The rack or plate's support rests on the slots or shaft holes in the grilling base. Skewer holders are located around the inside of the enclosure, and the inner walls of the enclosure feature grill walls with supporting edges for attaching food. The enclosure, top cover, and grilling base together form a relatively enclosed grilling space. Alternatively, the top cover and enclosure can be separated to create an open grilling space.

[0007] The method of using this invention patent application includes the following steps: S1, Installation: Place the baking base on top of the gas stove burner and rack, then combine the heat storage and heat conduction plate with the baking base. Next, place the grill rack or baking plate on the baking base, that is, on top of the heat storage and heat conduction plate. The support for the grill rack or baking plate is placed in the slot or shaft hole of the baking base. S2, Preparation for Use: Turn on the gas ignition and wait until the heat storage and heat conduction plate heats to a certain temperature or its appearance turns red. S3, Start Using: Place food on the grill rack, baking plate, or skewers. Place the skewers on the skewer holder inside the enclosure, or attach the food to the edge of the grill wall inside the enclosure. Use the heat source of the heat storage and heat conduction plate to heat and cook the food. Placing the enclosure and covering the top creates a relatively enclosed baking space, suitable for braising, baking, steaming, and other food cooking processes. Opening the top and removing the enclosure opens up an open grilling space, suitable for grilling, stir-frying, and sautéing. S4. During use, various food cooking processes can be used alternately and in combination; grilling can be done first, followed by baking. That is, the device can be opened to create an open baking space for grilling, stir-frying, sautéing, and other food cooking processes, and then the top cover can be closed to create a relatively closed baking space for braising, baking, steaming, and other food cooking processes. The reverse is also true.

[0008] This results in an environmentally friendly heat conduction baking device based on an existing fire source, namely a gas stove. This device forms a complete technical solution and a complete system that can encompass most of the cooking functions currently available on the market. Its social benefits and economic efficiency are immeasurable.

The embodiments described are only some embodiments of the present invention, and not all embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the claims, technical solutions, technical features, embodiments, optional solutions, technical teachings, etc. of the present invention without creative effort are within the scope of protection of the present invention. Figure 1The diagram shows a schematic representation of the main structure of an environmentally friendly heat conduction baking device based on a gas stove and its usage method. The device mainly consists of a baking base, a heat storage and conducting plate, an oil receiving tray, a grill rack, a baking plate, a surrounding enclosure, and a top cover. The baking base and heat storage and conducting plate are combined. The edge of the baking base has slots and shaft holes for placing the grill rack. The baking base is designed for use with the gas stove and its dimensions are larger than the stove's burner head and rack. The heat storage and conducting plate, combined with the baking base, is made of heat-conducting refractory material with a thickness of no more than 3 cm, serving to store, conduct, and radiate heat, obtaining a heat source without an open flame. The grill rack and baking plate are placed on the baking base and heat conducting plate, with their supports resting on the slots and shaft holes of the baking base. The top cover, combined with the baking base, forms a relatively enclosed baking space. Alternatively, the top cover can be separated from the baking base, creating an open baking space. The usage method includes the following steps: S1. Installation: Place the baking base above the burner and rack of the gas stove, then assemble the heat storage and heat conduction plate with the baking base. Next, place the grill rack or baking plate on the baking base, above the heat storage and heat conduction plate, with the rack or plate support placed in the slot or shaft hole of the baking base. S2. Preparation: Turn on the gas ignition and wait until the heat storage and heat conduction plate heats to a certain temperature or turns red. S3. Start using: Place food on the grill rack, baking plate, or skewers. Place the skewers on the skewer holder inside the enclosure, or place the food against the inner wall and edge of the enclosure. Use the heat source of the heat storage and heat conduction plate to heat and cook the food. Placing the enclosure and closing the top cover creates a relatively enclosed baking space, suitable for braising, baking, steaming, and other cooking processes. Opening the top cover and removing the enclosure opens up an open grilling space, suitable for grilling, stir-frying, and sautéing. S4. During use, various food cooking processes can be used alternately and in combination; grilling can be done first, followed by baking. That is, the device can be opened to create an open baking space for grilling, stir-frying, sautéing, and other food cooking processes, and then the top cover can be closed to create a relatively closed baking space for braising, baking, steaming, and other food cooking processes. The reverse is also true.

[0010] The working principle of this invention is as follows: When food needs to be cooked, the baking tray is placed above the burner and rack of the gas stove. The heat storage and conducting plate is then combined with the baking tray. Next, according to cooking needs, the grill rack and baking plate are placed on the baking tray, above the heat storage and conducting plate. The supports for the grill rack and baking plate are placed in the slots and shaft holes of the baking tray, respectively. Two types of oil collection trays are provided: one is located around the perimeter of the grill tray, and the other is located in the center of the baking tray, spaced apart. The oil collection trays are placed on the baking tray and the heat storage and conducting plate, with the grill rack or baking plate placed on top of the oil collection trays. This is used to collect oil droplets and juices generated during cooking, preventing them from falling into the heat source and igniting or causing smoke.

[0011] When the gas stove is ignited, the energy of the flame is transferred to the heat storage plate via heat radiation and conduction. Once the heat storage plate reaches a certain temperature or turns red, it indicates that the cooking temperature has been reached. At this point, food can be placed on the grill rack, baking plate, skewered, or placed on a skewer holder, or on the inner walls and sides of the grill enclosure. The heat from the heat storage plate heats the food, creating an energy conversion process primarily based on heat radiation and conduction, supplemented by convection. In this open state, the space is uncovered, allowing for grilling, stir-frying, and sautéing. When the lid is on, a relatively enclosed space is created, incorporating heat radiation, conduction, and convection from the heated air. This results in a fully interactive energy conversion process with faster, more efficient, and more balanced heat conversion. Its functionality is expanded to include braising, baking, steaming, and other cooking methods.
