Description

Technical Field

[0001] The invention relates to the field of barbecue equipment, and more particularly to an environmentally friendly self-adjusting heat and charcoal-saving barbecue stove. Background Art

[0002] A barbecue grill is a barbecue device suitable for all foods grilled over charcoal fire (including various meats and vegetables). It can be used to make grilled foods such as lamb skewers and barbecue, and can also be used for outdoor leisure and entertainment. At present, grilling food has evolved into a way of eating and socializing, so barbecue grills have evolved from being used by businesses at the beginning to gradually entering every household.

[0003] There are many kinds of barbecue grills on the market, but most of them are designed to take in air on the left and right sides of the grill body, and the air volume is manually adjusted by wind shields arranged on both sides of the grill body. This adjustment method is very inconvenient to use. It not only easily causes the barbecue grill to have high and uneven heat, but also consumes a large amount of charcoal due to the uncontrollable charcoal fire during use, resulting in a doubling of the amount of charcoal used. In addition, a large amount of unburned charcoal appears when cleaning the charcoal ash in the later stage, which wastes charcoal and labor. In addition, cleaning the charcoal ash in the later stage is also very inconvenient.

[0004] Therefore, how to improve the existing barbecue grill so that it can consume less charcoal, adjust the fire and air flow in real time, and easily clean the charcoal ash has become a problem that technicians in this field need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides an environmentally friendly self-adjusting heat and charcoal-saving barbecue grill.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

The smoke generating device as claimed in claim 13, wherein the smoke generating device comprises a smoke screen and a smoke screen, wherein the smoke screen is provided with a filter element and the smoke screen is provided with a filter element. The smoke screen is provided with a filter element which is configured to generate a smoke screen. The smoke screen is provided with a filter element which is configured to generate a smoke screen. The smoke screen is provided with a filter element which is configured to generate a smoke screen.

[0008] By adopting the above technical solution, the present invention solves the problems of the traditional oven charcoal fire heat cannot be regulated, the charcoal burns quickly, the charcoal dust pollution is large, the charcoal waste is serious, and the charcoal ash collection and cleaning is inconvenient. By setting a rotary air intake channel, the user can adjust the air intake volume in real time, control the charcoal fire combustion heat, and save the amount of charcoal; by setting a funnel-shaped slag discharge channel, the charcoal ash can automatically fall into the slag storage chamber for easy collection.

[0009] Preferably, a row of shelves is also provided at the upper end of the bracket to facilitate the placement of food to be baked or cooked or other related utensils.

[0010] Preferably, the storage rack is at the same height as the upper end of the air inlet chamber, preferably 700 mm, which is the most convenient height for users to take food or utensils.

[0011] Preferably, a heat insulation layer is provided inside the furnace surface above the rack, preferably an aluminum silicate heat insulation layer. The heat insulation layer can greatly absorb the heat in the furnace, ensuring that the temperature does not leak out, and avoid burning the human body during the barbecue process.

[0012] Preferably, a slag discharge drawer is provided in the slag discharge port below the slag storage chamber, and a handle is connected to the outer end of the slag discharge drawer, so that the charcoal ash leaking from the slag discharge channel will naturally roll into the slag discharge drawer for centralized storage, and the user only needs to pull out the slag discharge drawer to clean the charcoal ash.

[0013] Preferably, a circular rotating handle is provided at the outer end of the rotary air inlet passage, so as to facilitate the user to rotate the rotary air inlet passage in and out.

[0014] Preferably, the air inlet on the outer surface of the cylinder of the rotary air inlet channel is opened along the axial direction of the hollow cylinder, so that the opening size of the air inlet can be quickly and accurately adjusted, thereby achieving the adjustment of the air intake volume.

[0015] Preferably, universal casters are installed at the bottom end of the bracket to facilitate the barbecue oven to be flexibly moved and placed in any suitable position.

[0016] Preferably, a braking device is provided on the universal caster so that the barbecue oven will not move randomly when it needs to be parked.

[0017] Preferably, the rotary air inlet passage and the slag outlet are arranged on the same side of the furnace body, so that the user can adjust the air door or clean the carbon ash at any time.

[0018] Preferably, the furnace mouth at the upper end of the furnace body is processed into a groove form. The design of the furnace mouth groove guarantees the safety of hands to the greatest extent when baking food and prevents burns.

[0019] Preferably, the furnace body and the appearance of the bracket are all made of stainless steel, and the reflection of heat by the smooth surface ensures the secondary utilization of heat to the greatest extent.

[0020] Preferably, the height from the grill mouth to the ground is 950 mm, so there is no need to bend over or raise arms when using it, which is in line with the principles of ergonomics.

[0021] Preferably, the height between the oven holes and the oven mouth on the hole-type oven grate in the barbecue oven is 75-80 mm. This design maintains the oven temperature and the requirements for food baking to the maximum extent.

[0022] Preferably, the barbecue oven can utilize the principle of ventilation to reasonably design the holes inside the lower side of the oven body, the size of the oven hole, and the air inlet of the rotary air intake structure, so that the air volume flow among the three is balanced, mutually restrained and coordinated.

[0023] The present invention is based on the principle of air thermal energy: after the air expands due to heat, the number of particles per unit volume is less than that of normal air, that is, the density of hot air is smaller than that of normal air. The buoyancy of the hot air in the air will be greater than its gravity, so it will naturally float up.

[0024] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses an environmentally friendly self-adjusting heat and charcoal-saving barbecue grill, which has the following beneficial effects:

[0025] 1. Make full use of the principle of air flow to assist combustion or stop combustion and keep warm. By adjusting the size of the air inlet on the rotary air inlet channel, the air intake volume in the furnace can be adjusted, which directly affects the burning speed of the charcoal fire and further affects the temperature in the oven. In this way, the user can grasp the burning heat of the charcoal fire in real time and can adjust the appropriate temperature in the oven according to the type of food, which improves the taste of the food and saves the amount of charcoal accordingly.

[0026] 2. By isolating the entire furnace body into sections and controlling the temperature separately, the mixing of heat from different furnace areas is isolated, forming barbecue areas suitable for different foods, ensuring the grilled taste of different types of food.

[0027] 3. Utilizing the principle of air thermal energy, the buoyancy of hot air in ordinary air is greater than its gravity. When fresh air rushes into the furnace body and the charcoal fire heats up rapidly in a state of saturated oxygen, reaching the baking heat. As part of the burning charcoal breaks into pieces and falls to the bottom of the furnace, the air at the bottom expands due to the heat, and the heat rises rapidly to the furnace hole. At this time, a small amount of charcoal fire plus the rising heat can directly roast the food on the edge of the furnace, and the combined heat of the two can keep the heat for a longer time, ensuring the stability and reliability of the temperature. It not only saves labor and charcoal, but also reduces smoke and dust, making it more environmentally friendly.

[0028] 4. The ramp-type ash discharge structure design of the funnel-shaped slag discharge channel allows the slag and ash produced in the furnace to naturally roll into the slag storage chamber after falling, without the need for manual cleaning, which is convenient and quick.

[0029] 5. The structure of the present invention utilizes the principle of a funnel, which further enables the heat to be more concentrated.

[0030] 6. The slag drawer at the bottom of the slag discharge channel allows people to extract and clean the concentrated charcoal ash at one time, which is convenient, fast and labor-saving.

[0031] 7. By arranging a plurality of baking areas on the oven and adding a shelf, the present invention is transformed from an oven into a baking table, and its practicality and ornamental value are improved.

[0032] 8. The all-stainless steel exterior is used, and the principle of stainless steel reflection is utilized to make the stove surface temperature higher, making the food safe, beautiful, and easy to clean during preparation.

[0033] 9. The bottom of the bracket is equipped with universal casters that can be braked at any time, making it easy to push and stop the oven with high flexibility. Merchants can use it to improve the flexibility of restaurant decoration, and families can use it to easily move the barbecue position at any time, which greatly improves the applicability of this product.

[0034] 10. The present invention saves charcoal and labor, has strong operability, and users can use it by themselves after simple learning. When used by merchants, it can effectively shorten the time for serving dishes, improve the utilization rate of the oven, greatly reduce labor costs, and comprehensively reduce the operating costs of restaurants. When used by families, it can also greatly enhance the fun of barbecue. BRIEF DESCRIPTION OF THE DRAWINGS
