[0039] A box-type oven according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0040] Reference Figure 1 and Figure 2 The utility model aims to provide an embodiment of a box-type oven. The utility model aims to reduce the temperature of the outer surface of the oven, which helps to reduce burns and improve the safety of use. At the same time, reducing the temperature of the outer surface of the oven is also conducive to promoting the portability and practicality of the box-type oven.

[0041] In this embodiment, the box-type oven includes a box body 1 and a box cover 2. When in use, the box body 1 is mostly leaning downward, and the box body 1 is directly placed on the ground, a table top or a countertop, while the box cover 2 is mostly rotatably installed on the box body 1. The box cover 2 can be flipped upward to open, thereby exposing the top of the box body 1, which is convenient for placing food to be cooked in the box body 1. When the box cover 2 covers the box body 1, it can reduce heat loss, facilitate increasing the temperature, and improve the heating efficiency.

[0042] In some specific embodiments of the present invention, the box cover 2 and the box body 1 can be locked by a lock to prevent the box cover 2 and the box body 1 from being separated from each other during transportation and carrying.

[0043] In some specific embodiments of the present invention, the box body 1 may be provided with a handle for easy carrying.

[0044] In this embodiment, a receiving cavity 3 is formed between the box body 1 and the box cover 2, and the main volume of the receiving cavity 3 can be located in the box body 1, thereby increasing the cooking space and improving the utilization rate.

[0045] In some specific embodiments of the present invention, the box cover 2 can also form a part of the accommodating cavity 3 to increase the volume of the accommodating cavity 3 .

[0046] In some specific embodiments of the present invention, the box body 1 or the box cover 2 may be provided with a heating assembly or a heating element 28 to provide various heating methods.

[0047] When performing cooking operations or storage operations, people may misjudge the temperature of the outer surfaces of the box body 1 and the box cover 2 and easily touch the outer surfaces of the box body 1 and the box cover 2, resulting in burns.

[0048] At the same time, the temperature of the outer surface of the box-type oven is relatively high, which also means that more heat is lost, reducing the thermal efficiency of heating food. It is necessary to increase the output power of the box-type oven, which increases energy consumption.

[0049] In order to reduce the risk of scalding and improve the heating efficiency, the utility model reduces the heat conduction from the accommodating cavity 3 to the outside. Specifically, at least one of the box body 1 and the box cover 2 includes an inner shell and an outer shell, the inner side of the inner shell is used to form the accommodating cavity 3, the outer shell is located on the outer side of the inner shell, and a gap is set between the inner shell and the outer shell.

[0050] In some specific embodiments of the present invention, the box body 1 and the box cover 2 may both include an inner shell and an outer shell, thereby reducing the temperature of the outer surface of the box-type oven to the greatest extent and reducing the risk of scalding.

[0051] In this embodiment, at least one of the box body 1 and the box cover 2 includes an inner shell and an outer shell. Therefore, when the inner shell is heated, due to the gap between the inner shell and the outer shell, it is difficult for the heat to be transferred to the outer shell in large quantities through heat conduction, thereby lowering the temperature of the outer shell and reducing the risk of scalding. At the same time, since the heat conduction to the outside is reduced, when the box cover 2 covers the box body 1 for heating, the temperature of the accommodating cavity 3 can be made higher, thereby improving the thermal efficiency and helping to reduce energy consumption.

[0052] When the box body 1 includes an inner shell and an outer shell, the risk of scalding the human body by the box cover 2 when the box-type oven is stored can be reduced, and the risk of scalding by accidentally touching the box body 1 during cooking operations can be reduced.

[0053] Furthermore, when the temperature of the inner shell is high, the storage operation can be completed by touching the outer shells of the box body 1 and the box cover 2, without waiting for the inner shell to cool to room temperature, which less affects the portability and practicality of the box-type oven.

[0054] Reference Figure 3 Taking the box body 1 as an example, the inner shell of the box body 1 is the first shell 4, and the outer shell of the box body 1 is the second shell 5. Among them, a baking tray or a grill can be set in the first shell 4 to support food and facilitate cooking. And the outer side of the second shell can be provided with a handle, a lock, a knob, etc. for carrying, and also convenient for adjusting the heating power of the box-type oven.

[0055] Reference Figure 3 and 4 For the first shell 4, the first shell 4 includes a first folding plate 14 and two first brackets 15. The first folding plate 14 is used to form the bottom wall and two opposite side walls of the accommodating cavity 3. The two first brackets 15 are used to form the other two opposite side walls of the accommodating cavity 3 and fix the first folding plate 14 to the second shell 5.

[0056] It is easy to understand that in this embodiment, by using the first folding plate 14, the main part of the accommodating cavity 3 can be formed by bending the metal plate, thereby reducing the number of parts and components and lowering the manufacturing cost. At the same time, it is beneficial to improve the sealing of the accommodating cavity 3, reduce heat loss, and reduce the leakage of oil and debris.

[0057] The two first brackets 15 can form the other two side walls of the accommodating cavity 3, which not only takes into account the need to form the accommodating cavity 3, but also facilitates the installation of the first folding plate 14. Moreover, when heat is transferred outward through the first brackets 15, the physical path is small and the heat transfer is low, which is conducive to cooling.

[0058] In some specific embodiments of the present invention, the two first brackets 15 can be located at both ends of the box body 1 in the length direction, thereby reducing the space occupied by the first brackets 15. At the same time, the arrangement area of ​​the first folding plate 14 is larger, so that the volume of the accommodating cavity 3 is larger, which is convenient for placing more food.

[0059] In some specific embodiments of the present invention, the first shell 4 may include two connecting plates 16 connecting two opposite sides of the first folding plate 14 , and the connecting plates 16 are located on the top of the first bracket 15 .

[0060] It is easy to understand that in this embodiment, by providing two connecting plates 16, two opposite sides of the first folding plate 14 can be connected to accurately control the shape of the first folding plate 14, reduce bending rebound, and facilitate installation.

[0061] Furthermore, by providing the connecting plate 16, a circle of enclosure can be formed on the top of the first folding plate 14, thereby increasing the effective height of the accommodating cavity 3 and reducing the heat carried away by the lateral wind, which is conducive to efficient heating of food.

[0062] In some specific embodiments of the present invention, when the box cover 2 covers the box body 1 , the top of the first shell 4 can protrude into the box cover 2 .

[0063] Intuitively, the upper end of the first shell 4 protrudes from the end surface of the box body 1 facing the box cover 2 and is arranged along the circumference of the accommodating cavity 3 .

[0064] More specifically, the portion surrounded by the connecting plate 16 and the top of the first folding plate 14 is inserted into the portion of the box cover 2 used to form the accommodating cavity 3, forming an up and down staggered pattern, thereby reducing heat loss caused by air flowing along the gap between the box body 1 and the box cover 2, which is beneficial to increasing the temperature of the accommodating cavity 3 and improving thermal efficiency.

[0065] In some specific embodiments of the present invention, the box cover 2 can have an inner shell and an outer shell. The lower end of the inner shell of the box cover 2 protrudes from the end surface of the box cover 2 facing the box body 1, and is arranged along the circumference of the accommodating cavity 3. When the box cover 2 covers the box body 1, the lower end is inserted into the inner cavity of the box body 1, which has the same thermal insulation effect and improves thermal efficiency.

[0066] In some specific embodiments of the present invention, the first shell 4 may include two connecting rods 17 connecting two first brackets 15 , and a first folding plate 14 is disposed between the two connecting rods 17 .

[0067] It is easy to understand that in this embodiment, by setting two connecting rods 17, the first folding plate 14 can be limited between the two first brackets 15 to prevent the two first brackets 15 from moving away from each other. Furthermore, the first folding plate 14 can be directly inserted into the first bracket 15 to complete the assembly, reducing the number of screws, and reducing the difficulty and cost of installation.

[0068] In some specific embodiments of the present invention, the connecting rod 17 can be made into a long strip to facilitate processing and installation.

[0069] For the first bracket 15 , in some specific embodiments of the present invention, the first bracket 15 may include a vertical plate 18 , and the vertical plate 18 is used to connect the first folding plate 14 so as to form a receiving cavity 3 with the first folding plate 14 , thereby simplifying the structure.

[0070] In some specific embodiments of the present invention, the vertical plate 18 may be provided with a long waist hole to reduce material consumption and facilitate the arrangement of wires. A flange may be provided at the long waist hole to enhance the strength of the vertical plate 18.

[0071] In some specific embodiments of the present invention, the two vertical panels 18 can be connected to side panels, and the side panels can be connected to handles, etc., so as to overcome the problem that the second shell 5 is too thin to have good strength, and the second shell 5 can focus on the appearance structure.

[0072] In some specific embodiments of the present invention, the first bracket 15 can include an upper horizontal plate 19 connected to the top of the vertical plate 18. The upper horizontal plate 19 is located on the side of the vertical plate 18 away from the first folding plate 14, which can not only fill the gap between the top of the first shell 4 and the top of the second shell 5 to prevent foreign objects from falling into, but also facilitate the positioning and installation of the first shell 4.

[0073] In some specific embodiments of the present invention, the first bracket 15 can include a lower horizontal plate 20 connected to the bottom of the vertical plate 18. The lower horizontal plate 20 is located on the side of the vertical plate 18 away from the first folding plate 14 to support the first folding plate 14 and the vertical plate 18, thereby improving the bearing capacity of the first shell 4 and preventing the first shell 4 from collapsing downward due to carrying food.

[0074] In some specific embodiments of the present invention, one of the upper cross plate 19 and the second shell 5 can be provided with a positioning hole 21, and the other of the upper cross plate 19 and the second shell 5 can be provided with a positioning pin 22. The positioning hole 21 and the positioning pin 22 are inserted and positioned up and down, and then the first shell 4 is accurately positioned, so that the position and gap between the first shell 4 and the second shell 5 are relatively fixed, ensuring that the temperature of the second shell 5 is reduced.

[0075] In some specific embodiments of the present invention, the first bracket 15 may further include a support column 23 , the top of the support column 23 is connected to the upper transverse plate 19 , and the bottom of the support column 23 is connected to the lower transverse plate 20 .

[0076] It is easy to understand that, in this embodiment, by providing the support column 23 , the positions of the upper cross plate 19 and the lower cross plate 20 can be limited, thereby improving the strength and stability of the first bracket 15 .

[0077] In some specific embodiments of the present invention, a through hole can be set inside the support column 23 to facilitate screws from the upper cross plate 19 downward through the support column 23 and the lower cross plate 20 to connect the bottom wall of the box body 1, thereby avoiding the screws from being skewed and not being installed properly.

[0078] In some specific embodiments of the present invention, at least one of the upper horizontal plate 19 and the lower horizontal plate 20 may be provided with heat dissipation holes to promote air circulation in the gap between the first shell 4 and the second shell 5 and reduce heat transfer caused by air heating.

[0079] In some specific embodiments of the present invention, a lower heat dissipation channel 6 can be provided between the first shell 4 and the second shell 5, an air inlet 7 connected to the lower heat dissipation channel 6 is provided at the bottom of the box body 1, and an upper heat dissipation hole 8 connected to the lower heat dissipation channel 6 is provided at the top of the box body 1, so as to form a stable upward airflow, increase air flow, and reduce heat transfer to the second shell 5.

[0080] In some specific embodiments of the present invention, a portion of the air inlet 7 can be located at the bottom of the first bracket 15, or a portion of the air inlet 7 can be located at the bottom of the first folding plate 14, thereby promoting air flow in multiple directions.

[0081] In some specific embodiments of the present invention, the upper heat dissipation hole 8 can be located on the upper horizontal plate 19, thereby facilitating the upward flow of air.

[0082] In some specific embodiments of the present invention, the vertical plate 18 can be provided with a vent 13, and the vent 13 is used to connect the lower heat dissipation channel 6 along both sides of the circumference of the box body 1, so that the air at the bottom of the first folding plate 14 flows toward the first bracket 15, so as to discharge the air heated by the first folding plate 14.

[0083] In some specific embodiments of the present invention, the box cover 2 can be provided with an upper heat dissipation channel 9 connected to the lower heat dissipation channel 6, and the box cover 2 can be provided with lower heat dissipation holes 10 corresponding to the upper heat dissipation holes 8. The upper heat dissipation holes 8 and the lower heat dissipation holes 10 cooperate to allow air to enter the upper heat dissipation channel 9 from the lower heat dissipation channel 6.

[0084] It is easy to understand that, by providing the upper heat dissipation channel 9, this embodiment also facilitates directing the hot air in the box body 1 upward for easy discharge, without opening the box cover 2, and does not affect the heating of food.

[0085] In some specific embodiments of the present invention, the box cover 2 can be provided with an inner shell and an outer shell, the inner shell of the box cover 2 is the third shell component, the outer shell of the box cover 2 is the fourth shell component, and the upper heat dissipation channel 9 is formed between the third shell component and the fourth shell component. Therefore, it is convenient to form the upper heat dissipation channel 9 and can reduce the surface temperature of the box cover 2.

[0086] Reference Figure 2 In some specific embodiments of the utility model, the box cover 2 can be provided with an upper air outlet 11 or a side air outlet 12 connected to the upper heat dissipation channel 9. The upper air outlet 11 is provided to help accelerate the air flow and facilitate exhaust, while the side air outlet 12 can prevent the air from rising directly and scalding the human body, and also help to improve the waterproof ability and prevent rain from entering.

[0087] In some specific embodiments of the present invention, the lower horizontal plate 20 can be provided with a guide shell 24, and a waste discharge channel is formed between the guide shell 24 and the lower horizontal plate 20. The waste discharge channel accommodates the waste tray 26 of the box-type oven to enter and exit, and the vertical plate 18 is provided with an opening to accommodate the waste tray 26 to enter and exit.

[0088] It is easy to understand that, in this embodiment, by providing the guide shell 24, the movement of the waste tray 26 can be guided to reduce movement jams.

[0089] Moreover, an opening for the waste tray 26 to enter and exit is set on the vertical plate 18, and the waste tray 26 is also made into a long strip, which not only meets the need of collecting waste, but also can reduce the opening allowing the waste tray 26 to enter and exit, making the appearance of the box body 1 complete and simple.

[0090] Reference Figure 5 and Figure 6 In order to reduce the dirt of the first shell 4 or keep the first shell 4 clean, a waste collection assembly is arranged in the first shell 4, and the waste collection assembly includes two oil guide covers 25 that are opposite and inclined downward, and a waste tray 26 located below the two oil guide covers 25. Specifically, the top of the oil guide cover 25 is provided with an oil guide surface that is inclined downward, and the oil guide surface is used to guide oil and residue to gather the waste oil and residue. Therefore, when oil and residue drip, the oil and residue flow and gather downward along the oil guide surface of the oil guide cover 25, and finally drip into the waste tray 26.

[0091] In some specific embodiments of the present invention, the waste collection assembly may include a cross bar 27, the top of the oil guide cover 25 is buckled on the cross bar 27, and the oil guide cover 25 is provided with a downward bent edge for buckling.

[0092] It is easy to understand that in this embodiment, the cross bar 27 is provided so that the oil guide cover 25 has a bent edge, so that the top of the oil guide cover 25 can be directly placed up and down to fix it, which simplifies the installation of the oil guide cover 25 and also facilitates the removal and cleaning of the oil guide cover 25.

[0093] In some specific embodiments of the present invention, the cross bar 27 can be installed on the connecting plate 16, which is beneficial to increase the height and guide area of ​​the oil guide cover 25 and prevent oil stains and residues from falling in the direction where the two oil guide covers 25 are away from each other.

[0094] In some specific embodiments of the present invention, the first shell 4 may be provided with a heating element 28 , the heating element 28 includes a heating tube 29 and a protective cover 30 located on the top of the heating tube 29 , and the protective cover 30 supports the oil guide cover 25 .

[0095] It is easy to understand that in this embodiment, the heating tube 29 is provided, so that the heating tube 29 can heat the food as well as the oil stains on the oil guide cover 25, thereby preventing the oil stains from solidifying and adhering to the oil guide cover 25, thereby reducing the difficulty of cleaning.

[0096] It is easy to understand that, in this embodiment, by providing the oil guide cover 25, the oil guide cover 25 is heated first, and then the oil guide cover 25 radiates toward the food, so that the food is heated more evenly.

[0097] The protective cover 30 can prevent foreign matter from touching the heating tube 29, thereby reducing the probability of damage to the heating tube 29. At the same time, the porous structure of the protective cover 30 also facilitates heat dissipation.

[0098] The protective cover 30 supports the oil guide cover 25, which can prevent the oil guide cover 25 from rotating around the cross bar 27 and avoid restricting the shape of the cross bar 27.
