Description

Technical Field

[0001] The utility model relates to the technical field of skewer grills, in particular to an energy-saving smokeless skewer grill. Background Art

[0002] As a barbecue equipment, barbecue grill has a wide range of uses. It can be used to make barbecue foods such as grilled lamb skewers, barbecue, grilled vegetables, etc. Barbecue grills can be divided into charcoal barbecue grills, gas barbecue grills and electric barbecue grills according to different heating sources; according to different barbecue forms, they can be divided into manual barbecue grills and automatic barbecue grills; according to different uses, they can be divided into household barbecue grills and commercial barbecue grills, etc.

[0003] As barbecue grills are existing technology, researchers in related fields have been working on improving them. For example, the authorized patent with application number 201521029092.2 and subject name of an outdoor barbecue grill discloses that "a secondary barbecue grill is pulled out from the main barbecue grill, and a limiting device is used to limit and fix it, which greatly increases the area for grilling food. During the folding process, the secondary barbecue grill is pushed into the main barbecue grill, which is convenient for carrying and increases the area for grilling food."

[0004] From the technical content disclosed in the above-mentioned prior art, it can be seen that in addition to realizing the function of grilling and heating, the grilling area is increased by expanding the grilling structure. However, although the grilling area is increased, the heat source does not change from the essence of the function because it relies on a single source. Once the external use environment changes, the device is likely to become unsuitable. Therefore, in view of the problems that still exist in the prior art, the present application will provide an energy-saving smokeless barbecue stove to solve them. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , an energy-saving smokeless skewer grill, including an outer heat-insulated grill 1. A charcoal grill assembly 2 and an electric grill assembly 3 are sleeved inside the outer heat-insulated grill 1. The electric grill assembly 3 is located inside the charcoal grill assembly 2 and there is a clearance space between the internal structures of the electric grill assembly 3 and the charcoal grill assembly 2. A first anti-splash space and a second anti-splash space are respectively arranged on the inner sides of the charcoal grill assembly 2 and the inner sides of the electric grill assembly 3. Heat sources are arranged in both the first anti-splash space and the second anti-splash space. A main air intake groove is arranged at the bottom of the outer heat-insulated grill 1. A first auxiliary air intake structure and a second auxiliary air intake structure are respectively arranged on both sides of the charcoal grill assembly 2 and both sides of the electric grill assembly 3. Flow holes are opened on the side walls on both sides of the top of the charcoal grill assembly 2 and the side walls on both sides of the top of the electric grill assembly 3;

[0030] The charcoal grill assembly 2 includes an elastic charcoal stove body 21, angle iron frames 22, charcoal boxes 23, and first air vents 24. There are two first anti-splashing spaces, which are respectively arranged on both sides of the elastic charcoal stove body 21. There are two angle iron frames 22 and two charcoal boxes 23. The two angle iron frames 22 are respectively installed on the inner walls of the two anti-splashing spaces. The two charcoal boxes 23, as the heat sources of the charcoal grill assembly 2, are respectively installed inside the two angle iron frames 22. Thus, by utilizing the unique structural characteristics of the elastic charcoal stove body 21, the oil droplets generated during barbecue are kept away from the heat source, thereby minimizing the probability of generating oil fumes due to the heating of the oil droplets.

[0031] The first air vents 24 are opened on the side wall of the elastic charcoal stove body 21 as the first auxiliary air intake structure, and the number of the first air vents 24 is not less than two and is opened on the side walls on both sides of the elastic charcoal stove body 21 in an evenly distributed manner. Thus, during the process of the charcoal box 23 receiving charcoal and burning for heating, the heated air between the charcoal grill assembly 2 and the outer heat-insulating oven 1 can enter the interior of the elastic charcoal stove body 21 through the first air vents 24, optimizing the heat source supply effect during the barbecue process. The front and rear ends of the elastic charcoal stove body 21 are both open structures, and first baffles 25 are installed on the bottom inner walls at the front and rear ends of the elastic charcoal stove body 21. The two first baffles 25 and the bottom structure of the elastic charcoal stove body 21 form a first oil storage space aligned with the open space at the top of the elastic charcoal stove body 21, thereby centrally collecting the oil droplets generated during barbecue. At the front and rear ends on both sides of the top of the elastic charcoal stove body 21, first hooks 4 are fixedly connected, and the four first hooks 4 are grouped in pairs and respectively clamped on both sides of the top of the outer heat-insulating oven 1. Thus, while ensuring the stability of the composition of the charcoal grill assembly 2 and the outer heat-insulating oven 1, the flexibility of reciprocating disassembly and installation is maintained.

[0032] The electric grill assembly 3 includes an elastic electric stove body 31, second air vents 32, an electric heating component 33, and a second baffle 34. There are two second anti-splashing spaces, which are respectively arranged on both sides of the elastic electric stove body 31. The electric heating component 33 is the heat source of the electric grill assembly 3 and is provided in two. The two electric heating components 33 are respectively installed in the second anti-splashing spaces on both sides of the elastic electric stove body 31. Thus, by utilizing the unique structural characteristics of the elastic electric stove body 31, the oil droplets generated during barbecue are kept away from the heat source, thereby minimizing the probability of generating oil fumes due to the heating of the oil droplets. The second air vents 32 are opened on the side of the elastic electric stove body 31 as the second auxiliary air intake structure, and the number of the second air vents 32 is not less than two and is opened on the side walls on both sides of the elastic electric stove body 31 in an evenly distributed manner. Thus, during the process of the electric heating component 33 starting to heat, the heated air between the electric grill assembly 3 and the outer heat-insulating oven 1 can enter the interior of the elastic electric stove body 31 through the second air vents 32, optimizing the heat source supply effect during the barbecue process.

[0033] The front and rear ends of the elastic electric furnace body 31 are both open structures, and second baffles 34 are installed on the bottom inner walls of the front and rear ends of the elastic electric furnace body 31, and the two second baffles 34 and the bottom structure of the elastic electric furnace body 31 form a second oil storage space aligned with the open space at the top of the elastic electric furnace body 31, thereby centrally collecting the oil droplets generated by barbecue, and the front and rear ends on both sides of the top of the elastic electric furnace body 31 are fixedly connected with second hooks 5, and four second hooks 5 are respectively clamped on both sides of the top of the external insulation oven 1 in groups of two, thereby ensuring the stability of the electric barbecue oven assembly 3 and the external insulation oven 1 while maintaining the flexibility of reciprocating disassembly and installation, and an installation space is provided on one side of the external insulation oven 1, and a movable door 6 is hingedly installed in the installation space, thereby providing the operator with a yield condition for directly adjusting the internal space structure of the external insulation oven 1.

[0034] Working principle:

[0035] Embodiment 1

[0036] For barbecue environments where it is difficult to supply electricity, such as in the wild or during camping, the electric barbecue grill assembly 3 can be removed and the charcoal barbecue grill assembly 2 can be used alone for charcoal barbecue. The specific operation is as follows:

[0037] The four second hooks 5 are lifted up until they are all separated from the top structure of the external heat preservation oven 1. Then, pressure is applied to both sides of the elastic electric furnace body 31 to make the structures on both sides of the elastic electric furnace body 31 move similarly with elastic deformation until they can be taken out from the internal space of the charcoal fire oven assembly 2, and then the electric heat barbecue oven assembly 3 is lifted and taken out.

[0038] Next, barbecue charcoal is placed inside the two charcoal fire boxes 23 and ignited, and then heat is output from the top opening structure of the outer heat-insulating oven 1 and the top opening structure of the flexible charcoal fire furnace body 21. At the same time, the air between the flexible charcoal fire furnace body 21 and the outer heat-insulating oven 1 is heated synchronously, and then hot air enters the interior of the charcoal fire oven assembly 2 through the plurality of first air guide holes 24 and is output in and out of the top opening structure of the outer heat-insulating oven 1 and the top opening structure of the flexible charcoal fire furnace body 21, thereby optimizing the barbecue heat source supply effect again, and avoiding direct contact between the charcoal fire and the skewers, reducing the probability of burning;

[0039] During the grilling process, the oil droplets dripping from the grilled meat will directly drip into the first oil storage space under the action of gravity and be collected centrally, thereby preventing the oil droplets from contacting the burning grilling charcoal inside the charcoal fire box 23, thereby reducing the amount of oil smoke generated;

[0040] After the charcoal fire has burned out, the heat preservation effect of the external heat preservation oven 1 can still maintain the residual heat heating for a period of time, and the air heated by the residual heat will flow to the top of the external heat preservation oven 1 through the drainage holes, and the skewers placed on the top of the external heat preservation oven 1 will be auxiliary kept warm.

[0041] Example Two

[0042] For a barbecue environment with sufficient power supply indoors, in the courtyard, etc., the charcoal grill component 2 does not need to be disassembled, and the electric grill component 3 can be directly used for barbecue. The specific operation is as follows:

[0043] Turn on the two electric heating components 33 inside the electric grill component 3, so that the two electric heating components 33 generate heat and output the heat from the top opening structure of the outer heat-insulating grill 1 and the top opening structure of the elastic electric furnace body 31. At the same time, the air between the elastic electric furnace body 31 and the outer heat-insulating grill 1 is heated synchronously. Subsequently, the hot air enters the inside of the electric grill component 3 through a plurality of second air guide holes 32 and is output from and enters through the top opening structures of the outer heat-insulating grill 1 and the elastic electric furnace body 31, thereby optimizing the barbecue heat source supply effect again, and avoiding direct contact between the charcoal and the skewers, reducing the probability of scorching;

[0044] During the barbecue process, the oil droplets dripping from the roasted meat will directly drip into the first oil storage space under the action of gravity for centralized collection, thereby avoiding contact between the oil droplets and the electric heating components 33, and further reducing the generation amount of oil fume;

[0045] After the two electric heating components 33 are turned off, the heat preservation effect of the outer heat-insulating grill 1 can still maintain the afterheat heating for a period of time, and the air after the afterheat heating will flow through the diversion holes to the outside of the top of the outer heat-insulating grill 1 to assist in heat preservation for the skewers placed on the top of the outer heat-insulating grill 1.

[0046] Example Three

[0047] For the replacement and repair of the overall device and the cleaning after the use of the charcoal grill component 2 and the electric grill component 3, the charcoal grill component 2 and the electric grill component 3 can be disassembled respectively. Specifically, lift the four second hooks 5 upward until the four second hooks 5 are all disengaged from the top structure of the outer heat-insulating grill 1. Then, apply pressure to both sides of the electric grill component 3 to make the structures on both sides of the electric grill component 3 move in an approximate manner with elastic deformation until it can make way and be taken out from the internal space of the charcoal grill component 2, and then lift and take out the electric grill component 3;

[0048] Lift the four first hooks 4 upward until the four first hooks 4 are all disengaged from the top structure of the outer heat-insulating grill 1. Then, apply pressure to both sides of the elastic charcoal furnace body 21 to make the structures on both sides of the elastic charcoal furnace body 21 move in an approximate manner with elastic deformation until it can make way and be taken out from the internal space of the outer heat-insulating grill 1, and then lift and take out the charcoal grill component 2, and that's it.
