Description

Electric Multi-functional Barbecue Wood Stove Technical Field

[0001] This invention relates to a multifunctional stove for outdoor camping, picnics, and leisure travel, featuring automatic grilling and turning, heating and fire monitoring, as well as hot pot, frying, and stir-frying cooking. Background Technology

[0002] With rising living standards and increasing demand for leisure and entertainment, outdoor camping and barbecue parties have become popular social activities, satisfying people's pursuit of gourmet meals and leisure travel, and enriching social interaction methods. This has led to a booming market for barbecue grills, wood-burning stoves, and fireplaces. The main consumer groups include camping enthusiasts, outdoor adventurers, and residents seeking unique leisure experiences. These consumers exhibit diverse and personalized demands, focusing not only on the basic cooking and heating functions of products but also on their portability, safety, environmental friendliness, and multifunctionality. Technical issues

[0003] Currently, the market offers a wide variety of barbecue grills, wood-burning stoves, and fireplaces, but their functions are relatively limited. Consumers need to purchase and carry multiple different types of stoves, significantly reducing the economy, portability, and overall user experience. A brief summary of the classifications, advantages, and disadvantages of commonly used stoves is as follows:

[0004] Barbecue grills: Existing barbecue grills can be divided into traditional horizontal grills and hanging grills. Traditional horizontal grills come in two forms: manual food turning and automatic food turning via chain drive. Hanging grills adopt a barrel-shaped layout with charcoal fire in the middle. Food is hung inside the barrel for grilling. There are two ways to put food in and take it out: the top opening of the barrel and the side opening of the barrel.

[0005] The advantages of horizontal barbecue grills include convenient food handling, easy seasoning application, easy monitoring of food doneness, and low requirements for skewer shape and material. The main disadvantage is that with the charcoal directly below the food, dripping oil, brushing on oil, and sprinkling seasonings can generate thick smoke and even ignite, requiring immediate attention. Failure to address this promptly can result in the food being blackened or burnt, and it also has a significant impact on the surrounding environment. This drawback often leads to operator fatigue and a limited amount of food being grilled at a time, resulting in a poor experience for both the operator and diners during large gatherings. While automatic rotating grills can turn the food around, they don't solve the problems of thick smoke and ignition, still requiring manual operation. Furthermore, chain-driven rotating grills require special skewers placed in specific positions, making operation quite inconvenient.

[0006] The advantages of a hanging oven include minimal smoke as the food is positioned to the side of the charcoal fire, eliminating open flames, and the ability to cook a large quantity of food simultaneously. Disadvantages include difficulty in monitoring food doneness, leading to undercooked or burnt food; inconvenient food handling requiring special hooks or heat-resistant gloves; difficulty in turning food, resulting in inconsistent cooking or cumbersome operation; and the inability to easily spray seasonings during cooking, necessitating pre-marinating or spraying, which can cause the seasonings to burn and deteriorate the taste.

[0007] Wood-burning stoves and fireplaces: Existing wood-burning stoves and fireplaces are basically similar in function, providing heating for outdoor camping, home heating, and fire-watching entertainment. They primarily use wood and pellet fuel. Their advantage is that they can effectively meet the needs for heating and fire-watching entertainment. The disadvantages are that they lack cooking methods and functions, do not have traditional charcoal grilling capabilities, and their product functions and usage scenarios are relatively limited. Additional specialized stoves need to be purchased and carried as needed, making them less economical and portable. Technical solutions

[0008] This invention relates to an electric multi-functional barbecue wood-fired stove. It features a downward-opening oven door on the front and rear viewing surfaces of the stove body. An electric tilting module is located at the bottom of the tilting door, with a gear shaft and skewer clamp integrated into the module. The gear shaft and clamp module drive the skewers to rotate. A skewer rotation limiting groove is located at the top of the tilting door. Both parts are fixed to the overall tilting door design. The oven door is fitted with a high-temperature resistant, fire-resistant tempered glass window. Combined with the stove body, folding storage board, modular oven lid, chimney assembly, firewood tray, ash collection tray (oven), charcoal cage, grill rack, hot pot pan, frying pan, and large barbecue support, this invention overcomes the shortcomings of existing products and possesses corresponding advantages, achieving the following functions:

[0009] This invention integrates the electric tilting module at the bottom of the downward-opening oven door with the upper rotating limiting groove, enabling automatic rotation of food at 6-12 revolutions per minute during grilling mode. This ensures even heating and allows for the simultaneous grilling of a large quantity of food. The electric tilting module consists of a 5-12V low-voltage DC geared motor, a power control module, a transmission gear set, a gear shaft skewer clamp, and a housing. The power control module has two USB external power interfaces, allowing the entire system to operate simultaneously with an external power source and two modules connected in parallel via a USB cable. The external power source can be a DC 5-12V power bank or power adapter.

[0010] By precisely aligning the electric tilting module with the rotating limiting groove on the upper part of the oven door and forming an integral part with the tilting oven door, this structure enables the food to be tilted down and laid flat during the baking process, making it convenient and quick to spray seasonings and seasonings, and also making it convenient and safe to pick up and put down the food.

[0011] The downward-opening stove door has a glass window in the middle, made of high-temperature and fire-resistant tempered glass, to observe the cooking status of the food and to provide fire observation function when the stove is in wood-fired heating mode.

[0012] This invention employs a modular furnace lid design, consisting of a main furnace lid and extension lids. The main furnace lid has two extension lid positions, and the two sets of extension lids can be fixed to the main furnace lid to form a whole. These extension lid positions can be used to secure chimney components, pellet hoppers, or to hold kettles and cookware. The main furnace lid can be fully opened, allowing for the placement of hot pot pots, grill racks, and frying pans at the furnace opening, enabling various cooking methods such as hot pot, grilling, frying, and stir-frying.

[0013] The stove body of this invention has a charcoal cage and a charcoal cage rack inside. The charcoal cage rack can be adjusted up and down to fix the position of the charcoal cage, so as to adjust the height of the charcoal fire. In the storage mode, the charcoal cage, hot pot, frying pan, grill rack and other accessories can also be fixedly stored inside the stove body, making the structure compact and portable.

[0014] This invention features foldable storage panels on both sides of the stove body. When in use, these panels can be rotated and unfolded to hold condiments or food items. In storage mode, the two storage panels can be rotated and folded together to serve as handles for the stove.

[0015] The present invention allows for the installation of detachable large-sized barbecue racks between the side panels and the oven body. These racks can be used for grilling and cooking large pieces of food such as legs, ribs, chicken, and duck. The racks can be disassembled and stored inside the oven body.

[0016] The lower part of the enclosed furnace body is equipped with a firewood tray for placing burning wood. With the cooperation of the combined furnace cover and chimney assembly, the firewood stove heating mode is realized. In this mode, the fire can be observed and the heating can be achieved from both the front and back of the furnace body. The fuel used is firewood or pellets.

[0017] An ash collection tray (for ovens) is installed under the firewood tray and the downward-folding oven door. This tray is equipped with a thermometer and can be used to collect oil or ash in grilling or heating modes. It can also be used as a food oven by adding a cover or wrapping food in aluminum foil.

[0018] The bottom of the stove body has folding legs, which can be unfolded to raise the stove body for easy operation and make it more stable and safe. When folded, they can be stored at the bottom of the stove, making the structure compact. Beneficial effects

[0019] This invention overcomes the shortcomings of existing products, such as easy ignition of charcoal smoke, cumbersome food handling, complicated turning and seasoning, limited food processing capacity, single cooking method, and lack of fire-watching and heating functions. It is a multi-functional stove that features automatic food turning during grilling, no open flame or smoke from charcoal, convenient food handling and seasoning distribution, simultaneous cooking of multiple foods, multiple cooking methods including frying, stir-frying, hot pot, and grilling, and also provides heating and fire-watching functions.
