Description

Technical Field

[0001] This utility model relates to the field of barbecue grill technology, and in particular to a smokeless barbecue grill. Background Technology

[0002] A charcoal grill is a type of barbecue equipment used to grill lamb skewers, meat, vegetables, and other barbecued foods. Essentially, a charcoal grill heats and cooks food using a heat source. Depending on the heat source, charcoal grills can be categorized into wood-fired charcoal grills, gas-fired charcoal grills, and electric charcoal grills.

[0003] Currently, charcoal grills on the market can be divided into direct-heating and indirect-heating types based on the location of the heating source. Direct-heating grills place the heating source directly below the grill pan or rack and are equipped with insulation to prevent heat loss. While this design ensures efficient heating of food, oil produced during grilling, as well as cooking oil and seasonings used, can easily drip directly into the high-temperature charcoal or heating element, resulting in a large amount of oily smoke. This is environmentally unfriendly and can easily affect people's health.

[0004] Indirect heating charcoal grills place the heat source in the center and the grilling area on the periphery. This design, to avoid smoke, prevents grilling in the central area, wasting valuable grilling space (of course, if smoke isn't a concern, the central area can be used for grilling). Furthermore, in actual use, oil or seasonings produced in the outer grilling area tend to accumulate towards the center and can easily fall into the central heat source, still generating some smoke. To address these issues, I previously applied for a utility model patent (application number 202520149974X) entitled "A Multifunctional Smokeless Barbecue Grill." However, in practical applications, this grill's structure is still relatively complex, its purchase cost is high, and its overall weight is relatively heavy, resulting in slightly poor portability. Moreover, many people only need a grill rack. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a smokeless barbecue grill.

[0006] The technical solution adopted by this utility model is: a smokeless barbecue grill, comprising: The furnace body has an upward opening and an annular heating chamber inside. The furnace body is provided with several air inlets for introducing external air into the heating chamber. A heating source is installed in the heating chamber; A cover, installed on the furnace body, is used to cover all the areas above the heating chamber, and an opening is provided at the center of the upper end of the cover; The baking rack is placed on the opening accordingly; An oil and water tray is placed inside the oven body and is positioned directly below the baking rack. The heating chamber is arranged around the oil and water tray.

[0007] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0008] Preferably, the furnace also includes a chassis, the furnace body includes a carbon basin, the lower end of the carbon basin is provided with a plurality of foot supports for cooperating with the placement above the chassis, the lower end of the cover is arranged around the carbon basin, and the upper end of the cover is located above the carbon basin.

[0017] Compared with the prior art, this utility model has the following beneficial effects: 1. The barbecue grill can be assembled with only 5 accessories: base, charcoal basin, cover, oil and water tray and grill rack. It also has the function of smokeless grilling. The overall structure is simpler, the purchase cost is lower, and the portability is better. 2. It adopts an external heating method, and with the ash collection hole continuously supplying air into the heating chamber, the charcoal in the heating chamber will burn very strongly. Since the heating chamber is ring-shaped, the heat from all sides will gather in the center, thus heating the inner area more quickly. Food placed on the grill will also be cooked. The oil and water on the grill will flow down into the oil and water tray located directly below the grill and will not flow into the charcoal. It can ensure that there is virtually no smoke during use, making it very suitable for home barbecue. 3. It is more convenient to use. Simply open the cover to add charcoal to the charcoal basin or clean the ash. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0025] Specific implementation plan: Example 1: See Figures 1-7 This utility model is a smokeless barbecue grill, comprising: The furnace body has an upward opening and an annular heating chamber inside. The furnace body is equipped with several air inlets for introducing external air into the heating chamber. The heating source is installed in the heating chamber; The cover is installed on the furnace body and is used to cover all the areas above the heating chamber. An opening is provided at the center of the upper end of the cover. The baking rack is placed on the opening; The oil and water pan is placed inside the oven body and is positioned directly below the baking rack, with the heating chamber arranged around the oil and water pan.

[0026] As a preferred embodiment of this invention, it also includes a chassis 1, and the furnace body includes a carbon basin 2. The lower end of the carbon basin 2 is provided with a plurality of foot supports 25 for cooperating with the chassis 1. The cover 4 is placed above the carbon basin 2.

[0027] In addition, to ensure that all the oil and water dripping from the baking rack 5 can enter the oil and water tray 3 and will not splash into the heating chamber 26, in this embodiment, the coverage area of ​​the oil and water tray 3 is not smaller than the coverage area of ​​the baking rack 5.

[0028] In this embodiment, the heating source is charcoal, the air inlet is an ash collection hole 23, and it is located at the bottom of the charcoal basin 2.

[0029] To facilitate understanding, the working principle of the smokeless barbecue grill in this embodiment will be explained below: First, charcoal needs to be placed in the heating chamber 26. External air is continuously introduced into the heating chamber 26 through the ash collection hole 23, causing the charcoal in the heating chamber 26 to burn very vigorously. Designing the heating chamber 26 as a ring allows the heat generated by the burning charcoal in the heating chamber 26 to concentrate inward from all directions, thereby making the temperature of the inner area of ​​the charcoal basin 2 high enough that the grill rack 5 placed on the opening 41 can also be heated to a temperature sufficient to cook the food in a short time.

[0030] During the grilling process, the oil and water on the grill rack 5 will flow downwards into the oil and water tray 3 located directly below the grill rack 5. In this way, the oil and water will not flow into the charcoal fire, ensuring virtually no smoke during use, making it ideal for home grilling.

[0031] In practical applications, the annular shape of the heating chamber 26 can be circular, square, or polygonal.

[0032] Note that since the burning charcoal is located around the oil-water pan 3, the oil-water pan 3 is subjected to a high temperature, and therefore must be made of a high-temperature resistant material. Of course, to better ensure that the oil-water pan 3 is not damaged, an annular heat insulation plate can be installed between the oil-water pan 3 and the heating chamber 26. Additionally, to ensure that the heat generated by the burning charcoal in the heating chamber 26 is not blocked by the heat insulation plate, multiple slots spaced along its circumference can be optionally provided on the heat insulation plate.

[0033] Then, in this embodiment, the extension path of the cover 4 from the outer edge to the inner edge is a straight line or a curve, and both are located above the carbon basin 2.

[0034] Please see Figure 1 and Figure 2 As can be seen, the casing 4 is essentially a furnace lid, completely covering the heating chamber 26. Designing the outer contour of the casing 4 to extend in an arc or straight line ensures that a sufficiently large space is formed above the charcoal basin 2 for the charcoal to burn fully, thereby concentrating the heat inward.

[0035] Next, please continue reading. Figure 2 As can be seen, in this embodiment, the outer edge of the carbon basin 2 is provided with a first flange 22, and the outer edge of the cover 4 is provided with a second flange, with the first flange 22 and the second flange abutting against each other.

[0036] Here, the design of the first flange 22 and the second flange is to facilitate the placement of the cover 4 above the carbon basin 2. In addition, for better positioning and installation, in this embodiment, the edge of the first flange 22 is provided with an upwardly extending limiting strip.

[0037] Please see Figure 2 and Figure 5 As can be seen, in order to facilitate the positioning and installation of the oil and water pan 3, in this embodiment, a positioning groove 21 is provided at the center of the furnace bottom of the carbon pan 2, and the lower end of the oil and water pan 3 is placed in the positioning groove 21.

[0038] Please see Figure 2 and Figure 3 As can be seen, the bottom of the positioning groove 21 is provided with several dust collection holes 23.

[0039] Here, if you want to increase the heat and don't care about the smoke (such as when grilling outdoors), you can place the charcoal in the positioning groove 21, so that the food above the grill rack 5 is directly grilled. In this case, you need to set multiple ash collection holes 23 at the bottom of the positioning groove. Of course, if you only need to grill without smoke, you can choose not to set ash collection holes 23 at the bottom of the positioning groove 21.

[0040] Please see Figure 2 and Figure 4 As can be seen, in this embodiment, the edge of the opening 41 is provided with an inner ring edge 42, and the edge of the baking rack 5 abuts against the inner ring edge 42.

[0041] More specifically, at least one first handle 24 is provided on the outer wall of the carbon basin 2, and at least one second handle 43 is provided on the outer wall of the cover 4.

[0042] Here, the first handle 24 is designed to make it easy for users to move the carbon basin 2, and the second handle 43 is designed to make it easy for users to move the cover 4 and prevent them from being burned by high temperature.

[0043] Example 2: See Figure 8 and Figure 9 In this embodiment, a base plate 1 is also required, and the furnace body also includes a carbon basin 2. The lower end of the carbon basin 2 is also provided with several foot supports 25 for cooperating with the base plate 1. Unlike the first embodiment, the lower end of the cover 4 is arranged around the carbon basin 2, and the upper end of the cover 4 is located above the carbon basin 2.

[0044] Then, in this embodiment, the lower end of the cover 4 abuts against the top of the chassis 1, and the air inlet includes a second through hole 44 provided on the outer wall of the cover 4, a dust collection hole 23 provided at the bottom of the carbon basin 2, and a first through hole 27 provided on the outer wall of the carbon basin 2.

[0045] Next, in order to achieve the positioning and installation between the cover 4 and the carbon basin 2, in this embodiment, the upper edge of the carbon basin 2 is provided with a first flange 22, which abuts against the inner wall of the cover 4.

[0046] Note that in this embodiment, the base 1 is designed to facilitate placing the barbecue grill directly on the table for use. To reduce damage to the table, water can be added to the base 1.

[0047] In addition, in practical applications, the lower end of the cover 4 does not need to abut against the chassis 1, but instead leaves a certain air intake gap, so that there is no need to open a second through hole 44 on the cover 4.

[0048] Furthermore, in this embodiment, since the carbon basin 2 needs to be placed inside the cover 4, the first handle 24 cannot be provided on the carbon basin 2 as in the first embodiment. Instead, a second handle 43 can be provided on the cover 4.

[0049] Example 3: See Figure 10 and Figure 11 Unlike Embodiment 1, in this embodiment, the furnace body includes a furnace shell 6 and a carbon basin 2, and there is no need to set a base plate 1. The carbon basin 2 is placed inside the furnace shell 6, and the upper edge of the carbon basin 2 is provided with a first flange 22 for cooperating and abutting the upper end of the furnace shell 6. The cover 4 is placed above the carbon basin 2. The air inlet includes a third through hole 61 provided on the outer wall of the furnace shell 6, and an ash drop hole 23 provided at the bottom of the carbon basin 2.

[0050] In this embodiment, the lower end of the charcoal basin 2 does not contact the bottom of the furnace shell 6. The ash formed by burning charcoal in the charcoal basin 2 can fall onto the bottom of the furnace shell 6 through the ash drop hole 23. The furnace shell 6 can be placed directly on the table without burning the table.

[0051] Furthermore, in this embodiment, since the charcoal pan 2 is connected to the oven shell 6 via the first flange 22, there is no need to provide a foot support 25 at the lower end of the charcoal pan 2. Also, since the charcoal pan 2 needs to be placed inside the oven shell 6, a first handle 24 cannot be provided on the charcoal pan 2 as in Embodiment 1. To facilitate taking out the barbecue grill, a third handle can be provided on the outer wall of the oven shell 6.

[0052] The smokeless barbecue grill of this utility model described above is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
