Description

Technical Field

[0001] The general implementation of this utility model relates to the field of cooking equipment technology, specifically to a charcoal grilling device, and more particularly to a double-layer, multi-compartment smokeless grill. Background Technology

[0002] In existing technologies, charcoal grills are widely used in catering and family gatherings. However, existing charcoal grills present several inconveniences during use. For example, the long cooking time during charcoal grilling affects the diners' experience; some food may become charred, affecting the taste; the high temperature of the grill can cause burns during operation; and the grilling process produces a large amount of dense smoke. This smoke not only seriously pollutes the indoor environment and affects the health of users, but also damages the atmospheric environment when used outdoors. Existing technologies often require bulky and expensive specialized smoke extraction equipment to eliminate the smoke, which undoubtedly increases operating costs and installation space requirements.

[0003] Therefore, there is an urgent need in this field to provide an improved charcoal grilling device to solve the above-mentioned technical problems. Utility Model Content

[0004] According to some embodiments of this utility model, a charcoal grilling device is provided, including a chamber, a left guide plate, and a right guide plate. The chamber includes a left side wall, a right side wall, a front side wall, a rear side wall, and two partitions. The left side wall and the right side wall have the same shape. The front side wall and the rear side wall have the same shape, and the portions of the front side wall and the rear side wall that are higher than the left side wall and the right side wall are in the shape of an isosceles trapezoid. The left side wall, the front side wall, the right side wall, and the rear side wall form an open box shape. The two partitions are arranged between the left side wall and the right side wall, and one of the partitions is positioned vertically aligned with the left vertex of the isosceles trapezoid and is lower than the left side wall, thus connecting with the left side wall. The sidewall forms a barbecue charcoal box; another partition is positioned vertically aligned with the right vertex of the isosceles trapezoidal shape and is lower than the right sidewall, thus forming a barbecue charcoal box with the right sidewall; the barbecue charcoal box has a grate-shaped bottom; the left guide plate detachably covers the first opening formed by the upper edge of the left sidewall and the edges of the front and rear sidewalls corresponding to one waist of the isosceles trapezoidal shape, and the right guide plate detachably covers the second opening formed by the upper edge of the right sidewall and the edges of the front and rear sidewalls corresponding to the other waist of the isosceles trapezoidal shape, thereby forming a third opening with the upper edges of the left and right guide plates and the upper edges of the front and rear sidewalls.

[0005] In the aforementioned charcoal grilling equipment, the food skewers are placed parallel to the charcoal arrangement. This allows the hot airflow from the charcoal to be guided by a deflector plate, simultaneously heating and grilling the entire skewer. This ensures even heating, preventing localized burning while other parts remain uncooked. This invention achieves higher heating efficiency because the hot airflow from the charcoal is directed to the food skewers by the deflector plate, reducing heat loss from the open box structure compared to existing technologies. Furthermore, grease dripping from the food skewers does not fall onto the charcoal but instead drips through the space between the charcoal boxes, thus preventing excessive smoke.

[0006] Preferably, the charcoal grilling equipment according to the present invention further includes an outer shell, the chamber being arranged inside the outer shell, and the outer wall of the chamber being spaced apart from the outer shell.

[0007] Because the outer wall of the compartment is separated from the outer shell, the transfer of heat from the compartment to the outer shell is reduced, preventing the outer shell from becoming overheated and thus reducing the risk of burns.

[0008] Preferably, in the charcoal grilling equipment of the present invention, a grease and water collection tray is removably provided between the lower side of the chamber and the outer shell.

[0009] The grease trap not only collects dripping grease from the food skewers but also catches ash from the charcoal grill. This prevents the grill from becoming contaminated with grease and avoids the risk of burns from ash overheating the bottom of the grill.

[0010] Preferably, the charcoal grilling equipment of the present invention has ventilation holes on the side wall of the outer shell.

[0011] The ventilation holes allow for air circulation between the space between the compartment and the outer shell and the surrounding air, promoting heat removal from the outer shell and preventing burns caused by overheating.

[0012] Preferably, in the charcoal grilling equipment of this utility model, the ventilation hole is positioned at a height between the chamber and the grease and water receiving tray.

[0013] The ventilation holes are located between the compartment and the grease and water receiving pan, which avoids the compartment or the grease and water receiving pan from obstructing the airflow path through the ventilation holes, and is more conducive to convective heat transfer.

[0014] Preferably, in the charcoal grilling equipment of this utility model, two or more of the chambers are arranged inside the outer shell.

[0015] When two or more compartments are arranged inside the outer shell, each compartment is independent yet together forms a complete grilling system. When there are few diners, only one compartment is opened, avoiding waste of energy and space; when there are many people, multiple compartments are opened to meet the grilling needs of a large amount of food. This achieves a highly efficient and energy-saving technical effect. Attached Figure Description

[0021] The principles of this disclosure will now be described with reference to some exemplary embodiments. It will be understood that these embodiments are described for illustrative purposes only and to assist those skilled in the art in understanding and implementing this disclosure, and are not intended to limit the scope of this disclosure in any way. The disclosure described herein can be implemented in various ways other than those described below.

[0022] In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0023] References to "an embodiment," "embodiment," "example embodiment," etc., in this disclosure indicate that the described embodiment may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes that particular feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is suggested that such feature, structure, or characteristic be applied in conjunction with other embodiments to the knowledge of those skilled in the art, regardless of whether it is explicitly described.

[0024] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that, when used herein, the terms “comprising,” “including,” “having,” “containing,” “comprise,” and / or “containing” designate the presence of the stated features, parts, and / or components, but do not exclude the presence or addition of one or more other features, parts, components, and / or combinations thereof.

[0025] The term "connection" in this article includes direct connections, indirect connections, and integral molding.

[0026] Through extensive research and experimentation, the inventors discovered that most existing barbecue grills employ a single-layer, single-chamber structure, typically resembling a long, open box. Charcoal is placed at the bottom of the box, while the food is positioned at the top opening. During operation, the food is directly above the charcoal, causing dripping grease to fall directly onto the fire, instantly vaporizing and burning at high temperatures, producing large amounts of thick smoke.

[0027] Furthermore, the long, rectangular box structure prevents the effective collection of hot air generated during grilling. A large amount of hot air dissipates outwards, preventing the heat from reaching the food effectively. This results in low thermal efficiency, increasing both grilling time and energy consumption. Prolonged grilling also causes the heat from the charcoal to be transferred to the outer shell for an extended period, leading to overheating and potential burns.

[0028] Furthermore, in the existing technology of charcoal grills with their long, open box structure, the charcoal is arranged at a 90-degree angle to the food skewers, meaning they are perpendicular to each other. This arrangement results in uneven heating of the same skewer of food during grilling, with the ends of the skewer receiving significantly more heat than the middle due to their proximity to the heat source. This severely affects the taste and quality of the grilled food, failing to meet consumers' demands for high-quality grilling.

[0029] Therefore, this utility model proposes a novel and practical charcoal grilling device that can improve thermal efficiency, achieve uniform heating of food, avoid producing thick smoke, and prevent the outer shell from overheating.

[0030] For ease of description, the user's operating side is defined as the front side of the charcoal grilling equipment, and the side opposite the user's operating side is defined as the rear side of the charcoal grilling equipment. The user's left hand side is defined as the left side of the charcoal grilling equipment, and the user's right hand side is defined as the right side of the charcoal grilling equipment.

[0031] Figure 1 A charcoal grilling device 1000 according to some embodiments of the present invention is shown. Figure 1The image also shows food skewers 100. The longer portion of the food skewers 100 is located on the user-operated side of the charcoal grilling equipment 1000.

[0032] Figure 2 yes Figure 1 The front view of the charcoal grilling equipment 1000 shown. Figure 2 The dashed lines in the text represent the obscured parts.

[0033] Figure 3 yes Figure 1 The left side view of the charcoal grilling equipment 1000 shown. Figure 3 The dashed lines in the text represent the obscured parts.

[0034] See Figure 1 and Figure 2 The charcoal grilling equipment 1000 according to this utility model includes a chamber 200. The chamber 200 includes left and right side walls 202 and 203, and front and rear side walls 204 and 205. The left and right side walls 202 and 203 are identical in shape, as are the front and rear side walls 204 and 205. The side edges of the left side wall 202, front side wall 204, right side wall 203, and rear side wall 205 are connected to or close to each other but not connected, as long as the left and right side walls and the front and rear side walls form an open box shape. The front and rear side walls are higher than the left and right side walls. The portions of the front and rear side walls that are higher than the left and right side walls are in the shape of isosceles trapezoids. Figure 2 As shown, each compartment 200 includes left and right partitions 210. The partitions 210 extend parallel to the left and right side walls. The positions of the left and right partitions 210 are aligned vertically with the left and right vertices of the aforementioned isosceles trapezoidal shape, respectively. The height of the partitions 210 is lower than the height of the left and right side walls, thus the right partition 210 and the right side wall form a barbecue charcoal box 211, and the left partition 210 and the left side wall also form a barbecue charcoal box 211. The barbecue charcoal box 211 has a grate-like bottom plate to hold barbecue charcoal and allow ash to fall from the openings in the grate.

[0035] The charcoal grilling equipment 1000 according to this utility model further includes left and right guide plates 206 and 207. The left guide plate 206 can be installed to cover the opening formed by the upper edge of the left side wall 202 and the edges of the front and rear side walls corresponding to the left waist of the trapezoid. The right guide plate 207 can be installed to cover the opening formed by the upper edge of the right side wall 203 and the edges of the front and rear side walls corresponding to the right waist of the trapezoid. Thus, the upper edges of the left and right guide plates 206 and 207 and the upper edges of the front and rear side walls 204 and 205 form an opening. This opening is used to place food skewers 100. Preferably, the left guide plate 206 and the right guide plate 207 are detachably installed, thereby facilitating the storage and retrieval of barbecue charcoal from the barbecue charcoal box 211.

[0036] like Figure 1 and Figure 3 As shown, when using the chamber 200 for charcoal grilling, the burning charcoal can be placed in the charcoal boxes 211 on the left and right sides. The hot airflow from the charcoal is conducted upwards and guided to the opening after reaching the guide plates 206 and 207. The food skewers 100 are placed at this opening, with both ends of the skewers 100 placed on the upper edges of the front and rear side walls, respectively. Thus, the placement direction of the food skewers 100 is parallel to the arrangement direction of the charcoal, so that the hot airflow from the charcoal, after being guided by the guide plates 206 and 207, heats and grills the entire food skewer 100 simultaneously. This ensures that the food skewer 100 is heated evenly, preventing some parts from burning while others remain uncooked. Furthermore, compared to the existing elongated open-top box structure, this invention achieves higher heating efficiency. This is because the left and right guide plates 206 and 207 in this invention direct the hot airflow from the charcoal to the food skewers 100. In contrast, in the existing elongated open-top box structure, a portion of the hot airflow from the charcoal escapes directly from the opening without heating the food skewers, resulting in low heating efficiency. Moreover, since the food skewers 100 in this invention are placed at the opening, and the partition plates 210 are vertically aligned with the upper edges of the left and right guide plates 206 and 207, even if grease drips from the food skewers 100, it will not drip onto the charcoal but will instead drip through the space between the charcoal boxes 211 and into the grease-collecting tray 400. Therefore, this invention also achieves the technical effect of preventing dense smoke.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, according to some embodiments of the present invention, the charcoal grilling equipment 1000 further includes a housing 300, with the chamber 200 arranged inside the housing 300. A certain distance exists between the outer wall of the chamber and the housing 300 to reduce heat conduction, and the lower side of the chamber 200 is also spaced from the housing 300. For example, the housing 300 may be in the form of an open slot, through which the chamber 200 is inserted into or removed from the housing 300. For example, the chamber 200 may be detachably or removably installed inside the housing 300. For example, the chamber 200 may be non-detachably or non-removably installed inside the housing 300. For example, protrusions, mounting brackets, or mounting slots may be provided in the housing 300 so that when the chamber 200 is arranged inside the housing 300, a certain distance exists between the outer wall of the chamber and the housing. For example, additionally or alternatively, protrusions are provided on the outer surfaces of the left and right side walls and / or front and rear side walls of the compartment 200, such that when the compartment 200 is arranged within the outer shell 300, there is a certain distance between the outer wall of the compartment and the outer shell. Because heat conduction between the outer wall of the compartment and the outer shell 300 is reduced, the outer shell 300 will not overheat and pose a risk of burns even during grilling using the compartment 200. According to some embodiments of the present invention, no heat-insulating material is filled in the gap between the outer wall of the compartment and the outer shell 300. According to other embodiments of the present invention, the gap between the outer wall of the compartment and the outer shell 300 may be filled with heat-insulating materials commonly used in the art.

[0038] A grease trap 400 is removably disposed in the space between the lower side of the compartment 200 and the outer casing 300, thereby receiving not only oil dripping from the food skewers 100 but also ash falling from the charcoal box 211. This not only keeps the grilling equipment clean by receiving grease but also prevents the bottom of the outer casing 300 from heating up due to ash, thus avoiding the risk of burns. Preferably, an opening or a door for the grease trap 400 to enter and exit is provided on one side wall of the outer casing 300, allowing the grease trap 400 to be removably disposed between the lower side of the compartment 200 and the outer casing 300.

[0039] Preferably, a ventilation hole 301 is provided on the side wall of the outer casing 300 to allow air circulation between the space between the compartment and the outer casing and the surrounding air, thereby further transferring heat and reducing the risk of burns caused by the outer casing 300 overheating. More preferably, the ventilation hole 301 is positioned between the grease and water tray 400 and the compartment 200, thus avoiding obstruction of the flow path through the ventilation hole 301 by the grease and water tray 400 or the compartment 200, further facilitating air circulation.

[0040] According to some embodiments of this utility model, the outer shell 300 of the charcoal grilling equipment 1000 has two or more compartments 200 arranged inside. For example, as... Figure 1As shown in the example, there are three compartments 200. Of course, the specific number can be determined based on actual needs. This forms a double-layered, multi-compartment smokeless barbecue equipment. Each compartment 200 is independent yet collectively constitutes a complete barbecue system. Users can freely choose to open one or more compartments 200 for grilling operations based on the actual number of diners. When the number of diners is small, only one compartment is opened, avoiding energy and space waste; when the number of diners is large, multiple compartments are opened to meet the grilling needs of a large quantity of food. This achieves a highly efficient and energy-saving technical effect. Compared with existing technologies, this invention enables flexible use of multiple compartments, allowing the opening of an appropriate number of compartments according to actual needs. This avoids the energy waste problems of traditional single-compartment barbecue grills that require full power operation regardless of the amount of food and heat dissipation, effectively improving energy utilization efficiency and reducing operating costs.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
