Description

Technical Field

[0001] This utility model belongs to the technical field of steak cooking tools, specifically relating to a steak machine with heat insulation function. Background Technology

[0002] Currently, steak grilling at home typically requires a steak grill machine for easier cooking. Existing steak grill machines usually consist of a main body and a top cover. Some models, for better cooking results, also have a grill pan inside the main body and on the top cover. During steak grilling, the grill pan can reach temperatures exceeding 200 degrees Celsius. Current steak grill machines have a single-layer shell structure for both the main body and top cover, allowing the heat from the grill pan to be directly transferred to the shell, causing it to heat up too quickly. If a user accidentally touches the outside of the shell, there is a risk of burns. Therefore, further improvements are needed. Utility Model Content

[0003] This utility model provides a steak machine with heat insulation function, which aims to solve the problem that the steak machine in the prior art adopts a single-layer shell structure, resulting in a high temperature on the outer surface of the shell when the steak machine is working, which poses a risk of scalding the user.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A steak machine with heat insulation function includes:

[0006] The appliance body includes a cooking cavity within it, and a lower heating element located on the lower side of the cooking cavity. The appliance body comprises an inner casing surrounding the cooking cavity, an outer casing surrounding the side walls of the inner casing, and a connecting portion for connecting the inner casing and the outer casing. A heat-insulating cavity surrounding the cooking cavity is provided between the outer casing and the inner casing.

[0007] The upper cover is provided on the upper side of the cooking cavity. The upper cover includes an inner shell and an outer shell located outside the inner shell. A heat insulation cavity is provided between the outer shell and the inner shell. An upper heating assembly is provided on the lower side of the inner shell.

[0008] A further embodiment: the front side of the machine body is provided with a front opening communicating with the cooking chamber, and the steak machine also includes:

[0009] A drawer baking tray enters and exits the cooking cavity through the front opening. The drawer baking tray includes a panel for sealing the front opening and a cooking plate located behind the panel. The panel includes a front panel housing and a rear panel housing located behind the front panel housing. A panel heat insulation cavity is provided between the front panel housing and the rear panel housing.

[0010] Based on the above technical solution: by forming a panel insulation cavity between the front panel and the rear panel of the drawer baking tray, including the front panel housing and the rear panel housing located behind the front panel housing, heat transfer can be reduced, thereby reducing the temperature rise of the front panel housing and preventing users from being burned when touching the front panel housing, making it safer for users to push and pull the drawer baking tray; in addition, the design of the drawer baking tray also allows users to observe the cooking status of the food by pulling out the drawer baking tray without opening the top cover, which can avoid the problem of being burned by the upper heating element due to opening the top cover.

[0011] A further embodiment: the lower heating element is disposed on the underside of the cooking plate.

[0012] A further embodiment: The outer casing includes a left side wall, a right side wall, and a rear side wall, and the left side wall, right side wall, and rear side wall of the outer casing, together with the side wall of the corresponding inner casing, form the heat insulation cavity of the fuselage.

[0013] Based on the above technical solution: the above configuration forms heat insulation cavities on the left, right and rear sides of the body, which can effectively prevent users from being burned by accidentally touching the outer shell of the body.

[0014] A further embodiment: The fuselage also includes a bottom shell located below the outer shell and the inner shell of the fuselage, and a bottom heat dissipation cavity is provided between the bottom shell and the bottom wall of the inner shell of the fuselage, and the bottom heat dissipation cavity is in communication with the heat insulation cavity of the fuselage.

[0015] A further solution: The bottom shell is provided with heat dissipation holes that connect the bottom heat dissipation cavity to the outside.

[0016] Based on the above technical solution: by setting heat dissipation holes at the bottom of the bottom shell, the heat insulation cavity can dissipate heat outward through the heat dissipation holes by communicating with the bottom heat dissipation cavity, thereby further reducing the temperature rise of the outer shell of the fuselage.

[0017] A further option is to provide a cooling fan inside the heat insulation cavity of the fuselage; or, to provide a cooling fan inside the bottom heat dissipation cavity.

[0018] Based on the above technical solution: the cooling fan continuously discharges heat from the heat insulation cavity and the bottom heat dissipation cavity through the heat dissipation holes, thereby further reducing the temperature inside the heat insulation cavity and the bottom heat dissipation cavity, and thus reducing the temperature of the outer casing.

[0019] A further solution: When the cooling fan is located inside the heat insulation cavity of the fuselage, the cooling fan is located between the rear side wall of the inner casing and the rear side wall of the outer casing.

[0020] Based on the above technical solution, the above settings facilitate the installation of cooling fans.

[0021] A further embodiment: the connecting part includes an upper connecting shell located between the upper part of the inner housing and the upper part of the outer housing;

[0022] The upper ends of both the left and right sides of the inner housing are provided with bending portions that bend toward the outer housing of the corresponding side. The side of the bending portion near the inner housing is fixedly connected to the inner side of the upper connecting shell, and the side of the bending portion near the outer housing is fixedly connected to the outer side of the upper connecting shell and the outer housing.

[0023] Based on the above technical solution: the bending part serves two purposes: on the one hand, it connects the inner shell of the fuselage, the outer shell of the fuselage, and the upper connecting shell; on the other hand, it strengthens the fuselage structure between the inner shell and the outer shell of the fuselage.

[0024] A further embodiment: the outer shell of the upper cover is provided with a receiving groove with the slot facing downwards, the inner shell of the upper cover is located in the receiving groove, and the left side, right side and top of the inner shell of the upper cover and the outer shell of the upper cover form the heat insulation cavity of the upper cover; the front side of the upper cover is provided with an operation panel.

[0025] The beneficial effects of this utility model are as follows:

[0026] The steak machine of this utility model adopts a double-layer structure design of inner shell and outer shell, thereby forming a heat insulation cavity surrounding the cooking chamber between the inner shell and the outer shell. The heat insulation cavity can be set as an air layer or a vacuum layer, thereby reducing heat transfer and reducing the heat transferred from the inner shell to the outer shell. This can effectively reduce the surface temperature of the outer shell, so that when the user touches the outer shell during the cooking process, the user can avoid being burned.

[0027] The top cover includes an inner shell and an outer shell, thereby forming a heat insulation cavity between the inner shell and the outer shell.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 5 As shown, this embodiment provides a steak machine with heat insulation function, including:

[0038] A steak machine with heat insulation function includes:

[0039] The unit 1 includes a cooking cavity within it, and a lower heating element 35 located on the lower side of the cooking cavity. The unit 1 comprises an inner housing 11 surrounding the cooking cavity, an outer housing 12 surrounding the sidewalls of the inner housing 11, and a connecting portion for connecting the inner housing 11 and the outer housing 12. A heat insulation cavity 13 surrounding the cooking cavity is provided between the outer housing 12 and the inner housing 11. A certain distance is provided between the inner housing 11 and the outer housing 12. The heat insulation cavity 13 can specifically be an air layer to reduce heat transfer between the inner housing 11 and the outer housing 12.

[0040] The upper cover 2 covers the upper side of the cooking cavity. The upper cover 2 includes an inner shell 21 and an outer shell 22 located outside the inner shell 21. A heat insulation cavity 23 is provided between the outer shell 22 and the inner shell 21. An upper heating component 4 is provided on the lower side of the inner shell 21. In this embodiment, because the upper heating component 4 is provided on the inner shell 21, the heat insulation cavity 23 reduces the temperature rise of the upper heating component 4 on the outer shell 22. The outer shell 22 is specifically fixedly connected to the inner shell 21 by screws or the like. Specifically, the outer shell 22 has a receiving groove with the opening facing downwards. The inner shell 21 is located in the receiving groove, and the left, right, and top sides of the inner shell 21 and the outer shell 22 together form the heat insulation cavity 23. An operation panel is provided on the front side of the upper cover 2.

[0041] In some specific implementations, such as Figures 1 to 4 As shown, for user convenience, the front side of the machine body 1 is provided with a front opening communicating with the cooking chamber. The steak machine also includes:

[0042] The drawer baking tray 3 enters and exits the cooking cavity through the front opening. The drawer baking tray 3 includes a panel for sealing the front opening and a cooking plate 34 located behind the panel. The panel includes a front housing and a rear housing located behind the front housing. A heat insulation cavity 33 is provided between the front and rear housings. Since the rear housing is in direct contact with the heat inside the cooking cavity, it is prone to rapid temperature rise. Therefore, the heat insulation cavity 33 reduces heat transfer between the front and rear housings. When the user pushes or pulls the drawer baking tray 3, touching the front housing prevents burns, making the process safer.

[0043] In some specific embodiments, the lower heating component 35 can be disposed on the lower side of the cooking plate 34, which can more effectively heat the cooking plate 34. Alternatively, the lower heating component 35 can also be disposed at the bottom of the cooking cavity.

[0044] In some specific implementations, such as Figure 4 and Figure 5 As shown, the outer casing 12 includes a left side wall, a right side wall, and a rear side wall, and the left side wall, right side wall, and rear side wall of the outer casing 12, together with the side wall of the corresponding inner casing 11, form the heat insulation cavity 13. This creates a heat insulation cavity 13 surrounding the cooking cavity on the left, right, and rear sides of the casing 1, effectively preventing users from being burned by accidental contact with the outer casing 12.

[0045] In some specific embodiments, the machine body 1 further includes a bottom shell 15 located below the outer casing 12 and the inner casing 11. A bottom heat dissipation cavity 16 is provided between the bottom shell 15 and the bottom wall of the inner casing 11, and the bottom heat dissipation cavity 16 communicates with the machine body heat insulation cavity 13. Specifically, the bottom shell 15 is fixedly connected to the outer casing 12, and the bottom shell 15 is fixedly connected to the inner casing 11 via a connecting bracket, thereby forming a bottom heat dissipation cavity 16 between the bottom shell 15 and the bottom wall of the inner casing 11. To facilitate heat dissipation, a heat dissipation hole 151 communicating with the bottom heat dissipation cavity 16 and the outside is provided on the bottom shell 15. Specifically, since the machine body heat insulation cavity 13 communicates with the bottom heat dissipation cavity 16, when the steak machine is working, the heat in the machine body heat insulation cavity 13 can be dissipated to the outside through the heat dissipation hole 151 by communicating with the bottom heat dissipation cavity 16, thereby further reducing the temperature rise of the outer casing 12.

[0046] In some specific implementations, such as Figure 2 As shown, to further improve heat dissipation efficiency, a cooling fan 17 can be installed inside the heat insulation cavity 13 of the fuselage; or, a cooling fan 17 can be installed inside the bottom heat dissipation cavity 16. When the cooling fan 17 is working, it draws in cool air from the outside, passes through the heat insulation cavity 13 and the bottom heat dissipation cavity 16, and then discharges it through the heat dissipation hole 151. By continuously dissipating the heat in the heat insulation cavity and the bottom heat dissipation cavity 16 through the heat dissipation hole 151, the temperature of the outer casing 12 of the fuselage is reduced. When the cooling fan 17 is located inside the heat insulation cavity 13 of the fuselage, the cooling fan 17 is located between the rear side wall of the inner casing 11 and the rear side wall of the outer casing 12 of the fuselage. Specifically, an air inlet hole communicating with the cooling fan 17 can be provided on the rear side wall of the outer casing 12 of the fuselage.

[0047] In some specific implementations, such as Figures 1 to 5 As shown, the connecting part includes an upper connecting shell 14 located between the upper part of the inner housing 11 and the upper part of the outer housing 12;

[0048] The upper ends of both the left and right sides of the inner housing 11 are provided with bending portions 111 that bend toward the outer housing 12 on the corresponding side. The side of the bending portion 111 near the inner housing 11 is fixedly connected to the inner side of the upper connecting shell 14, and the side of the bending portion 111 near the outer housing 12 is fixedly connected to the outer side of the upper connecting shell 14 and the outer housing 12. To reduce the contact area between the inner housing 11 and the outer housing 12, the bending portion 111 is specifically a bending plate. Specifically, the lower end of the inner side of the upper connecting shell 14, near the inner housing 11, bends toward the heat insulation cavity 13 and is provided with several first connecting seats, which are fixedly connected to the bending portion 111. The side of the bending portion 111 near the outer housing 12 is fixedly connected to the outer side of the upper connecting shell 14 and the outer housing 12, specifically by means of screws or the like.

[0049] The outer casing 12 specifically includes a first casing 121 integrally formed from a left side wall, a right side wall and a rear side wall, and a second casing 122 located on the front side. The second casing 122 is fixedly connected to the front side wall of the inner casing 11 and the bottom casing 15.

[0050] Working principle explanation:

[0051] During operation, the heat insulation cavity 13 of the machine body reduces heat transfer between the inner shell 11 and the outer shell 12, thereby reducing the temperature rise of the outer shell 12. The heat insulation cavity 23 of the top cover reduces heat transfer between the inner shell 21 and the outer shell 22, thereby reducing the temperature rise of the outer shell 22. The heat insulation cavity 33 of the panel reduces heat transfer between the front panel shell 31 and the rear panel shell 32, thereby reducing the temperature rise of the front panel shell 31. This ensures that users are protected from burns when touching the outer side of the top cover 2, the outer side of the machine body 1, or the front side of the panel, making the steak machine safer to use.

[0052] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
