Description

Technical Field

[0001] This utility model relates to the field of food cooking technology, specifically to an electric oven. Background Technology

[0002] An electric grill is a type of barbecue equipment used to grill meat, vegetables, and other barbecued foods. Essentially, a grill uses a heat source to heat and cook food. Grills produce fumes during use, and when covered, these fumes need to be exhausted; therefore, an exhaust pipe is typically installed on the grill.

[0003] Because the exhaust pipe needs to discharge and guide harmful gases such as fumes, it needs to protrude from the outside of the electric oven, which increases the space occupied by the electric oven and increases transportation costs. Utility Model Content

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. Therefore, this utility model provides an electric oven with the advantage of small footprint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric oven includes an oven body with a heating space within it. A smoke vent is formed on the outer wall of the oven body and communicates with the heating space. The oven also includes a smoke exhaust pipe with an inlet, an outlet, and a smoke exhaust channel connecting the inlet and the outlet. The oven body includes a smoke outlet pipe with the smoke vent formed on it. The inlet of the smoke exhaust pipe is connected to the smoke outlet of the smoke outlet pipe. The smoke exhaust pipe is detachably mounted on the oven body. A smoke exhaust pipe protruding from the oven body would occupy more space during use or transportation. Making the smoke exhaust pipe detachable allows it to be removed when needed, reducing space occupied during transportation and lowering transportation and usage costs.

[0007] Optionally, the exhaust pipe includes a pipe body and at least one mounting part. The exhaust channel passes through the pipe body, and the mounting part is disposed on the outer wall of the pipe body near the inlet. The mounting part is used to fix the exhaust pipe to the furnace body. The mounting part is used to fix the exhaust pipe to the furnace body, thereby guiding harmful gases such as oil fumes and improving the stability of the fixation between the exhaust pipe and the furnace body.

[0008] Optionally, the mounting portion includes a mounting groove, a magnetic component, and a cover. The mounting groove and the cover form a fixing space for accommodating the magnetic component. The mounting portion is disposed opposite to the furnace body, and the furnace body includes an adsorption portion opposite to the mounting portion. The magnetic component is magnetically attracted to the adsorption portion to fix the exhaust pipe and the furnace body. The magnetic component is located between the cover and the mounting groove. When the exhaust pipe is fixed to the furnace body, the magnetic component provides an attractive force perpendicular to the outer surface of the furnace body and provides installation protection, thereby increasing the friction between the mounting portion and the furnace body and improving stability.

[0009] Optionally, the mounting part is located away from the oven cover relative to the main pipe body, and a gap is formed between the mounting part and the oven cover. The component inside the mounting part that securely connects the exhaust pipe to the oven body is a magnetic element. This magnetic element demagnetizes at high temperatures, weakening the connection between the exhaust pipe and the oven body. The gap between the mounting part and the oven body slows down the temperature rise of the magnetic element during oven operation. This is because the specific heat of the air in the gap is greater than that of the external structural materials of the mounting part or the oven body. Under the same heat diffusion conditions, the gap allows the air in the gap to absorb the same amount of heat but with a reduced temperature rise. This reduces the heat absorbed by the magnetic element from the air in the gap, lowers its temperature rise, extends its service life, reduces maintenance costs, and improves the fixation between the exhaust pipe and the oven body.

[0010] Optionally, the mounting groove is provided with a snap-fit ​​groove, and the cover is provided with a snap-fit. The snap-fit ​​engages with the snap-fit ​​groove for fixation, and the snap-fit ​​is located on the side of the cover facing the mounting part. The engagement of the snap-fit ​​and the snap-fit ​​groove fixes the cover to the mounting groove, improving the fixing effect between the cover and the mounting groove, preventing the magnetic components located in the mounting groove from falling out of the rising mounting groove, and ensuring the fixed relationship between the flue pipe and the furnace body.

[0011] Optionally, there are two mounting parts, which are respectively arranged opposite to each other on both sides of the pipe body. Arranging the two mounting parts on both sides of the pipe body can evenly distribute the weight of the exhaust pipe onto the two mounting parts, thereby reducing the force on each mounting part, increasing the maximum weight it can withstand, and improving the stability of the installation.

[0012] Optionally, there are two mounting sections, both located on the same side of the pipe body. Having the mounting sections on the same side offers advantages such as space saving and ease of installation.

[0013] Optionally, the inlet end of the exhaust pipe is sleeved and fixed to the exhaust outlet end of the smoke outlet pipe. One end of the exhaust outlet pipe extends into the inlet end of the exhaust pipe and abuts against it. The length of the exhaust outlet pipe extending into the exhaust pipe is between 1-10mm. Simply relying on magnetic attraction to the furnace body is insufficient to provide adequate support, and the need for alignment with the adsorption part during installation increases installation difficulty. However, providing an exhaust pipe provides a reference for the installation position of the exhaust pipe, and the sleeved fixation of the exhaust pipe helps to secure the exhaust pipe, achieving a more stable fixation effect and reducing installation difficulty. Simultaneously, the sleeved connection prevents fumes from escaping from the point of contact, resulting in better smoke extraction.

[0014] Optionally, the exhaust pipe has at least one convection port on its side wall, and the convection port is connected to the exhaust channel. When the exhaust pipe is working, the gas inside the convection port is high-temperature gas generated during the heating of food. Compared with the gas outside the convection port, the gas temperature inside the exhaust channel is higher, the pressure is lower, and the flow rate is faster. Therefore, near the convection port, the air pressure inside the pipe body is lower than the air pressure outside the pipe body. The gas outside the pipe body will enter the exhaust channel through the convection port due to the pressure difference. Then, since the rate of outflow from the exhaust channel is constant, but some of the gas outflowing from the exhaust channel comes from the air outside the convection port, the amount of high-temperature gas outflowing from the exhaust channel in the same amount of time is reduced. This reduces the rate at which heat is carried away from the heating space, thereby reducing the amount of heat carried away from the heating space and slowing down the temperature drop in the heating space.

[0015] Optionally, the furnace body includes a furnace base, a furnace cover, and a heating element. The furnace cover is pivotally connected to the furnace base, and the furnace cover fits onto the furnace base. The furnace cover and the furnace base enclose and form the heating space. The heating element is disposed within the heating space and is fixedly connected to the furnace base. The flue pipe is disposed on the furnace cover and can rotate with the furnace cover. The furnace cover is rotatably connected to the furnace base, and the furnace cover can be rotated open and closed, forming the heating space together with the furnace base. The flue pipe is disposed on the furnace cover and can move with the rotation of the furnace cover without obstructing the rotation of the furnace cover.

[0016] The advantages of this application are that it occupies little space and the heating space cools down slowly. It is also easy to disassemble and assemble, which can reduce the volume of the electric oven after storage, and ensure the stability of smoke exhaust and the convenience of installation.

The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0027] Example:

[0028] like Figure 1-2 As shown, an electric oven includes an oven body 1 with a heating space 11 inside. A smoke vent 12 is formed on the outer wall of the oven body 1, communicating with the heating space 11. The electric oven also includes a smoke exhaust pipe 2, which includes an inlet 21, an outlet 22, and a smoke exhaust channel 23 connecting the inlet 21 and the outlet 22. The oven body 1 includes a smoke outlet pipe 13 with the smoke vent 12 formed on it. The inlet 21 of the smoke exhaust pipe 2 is connected to the smoke outlet 12 of the smoke outlet pipe 13. The smoke exhaust pipe 2 is detachably mounted on the oven body 1. The smoke exhaust pipe 2 protruding from the oven body 1 would occupy more space during use or transportation. Making the smoke exhaust pipe 2 detachable allows it to be removed when needed, reducing space occupied during transportation and lowering transportation and usage costs.

[0029] like Figure 3 As shown, the exhaust pipe 2 includes a pipe body 24 and at least one mounting part 25. The exhaust channel 23 passes through the pipe body 24, and the mounting part 25 is disposed on the outer wall of the pipe body 24 near the inlet 21. The mounting part 25 is used to fix the exhaust pipe 2 to the furnace body 1. The mounting part 25 is used to fix the exhaust pipe 2 to the furnace body 1, which plays a guiding role for harmful gases such as oil fumes and can improve the fixed stability between the exhaust pipe 2 and the furnace body 1.

[0030] like Figure 4 As shown, the mounting part 25 includes a mounting groove 251, a magnetic component 252, and a cover 253. The mounting groove 251 and the cover 253 surround and form a fixed space for accommodating the magnetic component 252. The mounting part 25 is disposed opposite to the furnace body 1. The furnace body 1 includes an adsorption part opposite to the mounting part 25. The magnetic component 252 is magnetically attracted to the adsorption part to fix the exhaust pipe 2 and the furnace body 1. The magnetic component 252 is located between the cover 253 and the mounting groove 251. The magnetic component 252 can provide an attractive force perpendicular to the outer surface of the furnace body 1 and for installation protection when the exhaust pipe 2 is fixed to the furnace body 1, thereby increasing the friction between the mounting part 25 and the furnace body 1 and improving stability.

[0031] The mounting part 25 is located away from the oven cover 15 relative to the pipe body 24, and a gap is formed between the mounting part 25 and the oven cover 15. The smoke outlet pipe 13 extends into the exhaust pipe 2 and abuts against the exhaust pipe 2. The length of the smoke outlet pipe 13 extending into the exhaust pipe 2 is between 1-10 mm. The component inside the mounting part 25 that fixes the exhaust pipe 2 to the oven body 1 is a magnetic component 252. The magnetic component 252 will demagnetize at high temperatures. Losing magnetism will weaken the fixation between the exhaust pipe 2 and the oven body 1. The gap between the mounting part 25 and the oven body 1 can slow down the temperature rise of the magnetic component 252 when the electric oven is working. This is because the specific heat of the air in the gap is greater than the specific heat of the mounting part 25 or the external structural material of the oven body 1. Under the same heat diffusion conditions, the gap allows the air in the gap to absorb the same amount of heat but reduces the temperature rise, thereby reducing the magnetic component's temperature rise. The heat absorbed by the magnetic component 252 from the air in the gap reduces the temperature rise of the magnetic component 252, extends its service life, reduces maintenance costs, and improves the fixing effect between the exhaust pipe 2 and the furnace body 1. The magnetic component 252 attracting the furnace body 1 alone is not enough to provide sufficient support, and the need to align it with the adsorption part during installation increases the installation difficulty. However, the exhaust pipe 13 can provide a reference for the installation position of the exhaust pipe 2, and the exhaust pipe 13 is sleeved and fixed to the exhaust pipe 2, which can help fix the exhaust pipe 2, obtain a more stable fixing effect, and reduce the installation difficulty.

[0032] Specifically, the length of the exhaust pipe 13 extending into the exhaust pipe 2 is between 1-10mm, which ensures the magnetic positioning and fixing function while allowing the fumes to be completely discharged from the pipe body 24, preventing fumes from escaping through gaps due to the detachable magnetic fixing method. Furthermore, the outer plane of the mounting groove 251 is not on the same plane as the planes that contact the pipe body 24 and the furnace cover 15; the outer plane of the mounting groove 251 is positioned 1-2mm further back, preventing it from contacting the furnace cover 15. Since the magnetic component 252 will demagnetize at high temperatures, reducing its magnetism, the fact that the mounting groove 251 does not contact the furnace cover 15 reduces heat conduction to the magnetic component 252.

[0033] The mounting groove 251 is provided with a snap-fit ​​groove, and the cover 253 is provided with a snap-fit. The snap-fit ​​engages with the snap-fit ​​groove for fixation, and the snap-fit ​​is located on the side of the cover 253 facing the mounting part 25. The snap-fit ​​and snap-fit ​​groove work together to fix the cover 253 onto the mounting groove 251, improving the fixing effect between the cover 253 and the mounting groove 251, preventing the magnetic component 252 located in the mounting groove 251 from falling out of the mounting groove 251, and ensuring the fixed relationship between the exhaust pipe 2 and the furnace body 1.

[0034] like Figure 3As shown, there are two mounting parts 25, which are respectively arranged opposite to each other on both sides of the pipe body 24. The two mounting parts 25 are respectively arranged on both sides of the pipe body 24, which can evenly distribute the weight of the exhaust pipe 2 onto the two mounting parts 25, thereby reducing the force on each mounting part 25, increasing the maximum weight it can withstand, and improving the stability of the fixation.

[0035] like Figure 5 As shown, there are two mounting parts 25, and the two mounting parts 25 are arranged on the same side of the pipe body 24. Arranging the mounting parts 25 on the same side has the advantages of saving space and facilitating installation. In this embodiment, the two mounting parts 25 are fixed to the outer wall of the pipe body 24 and arranged side by side. One side of the mounting part 25 faces the furnace body 1, and the other side of the mounting part 25 is in contact with the outer wall of the pipe body 24. At this time, the cover 253 of the mounting part 25 is located on the inner wall of the pipe body 24, and the magnetic element 252 in the mounting groove 251 is installed into the mounting groove 251 through the flue gas passage 23.

[0036] The inlet 21 end of the exhaust pipe 2 is sleeved and fixed to the exhaust port 12 end of the exhaust pipe 13. One end of the exhaust port 12 of the exhaust pipe 13 extends into the inlet 21 end of the exhaust pipe 2 and abuts against the exhaust pipe 2. The length of the exhaust pipe 13 extending into the exhaust pipe 2 is between 1-10mm. Simply relying on magnetic attraction to the furnace body is insufficient to provide adequate support, and the need for alignment with the adsorption part during installation increases the difficulty. However, the exhaust pipe provides a reference for the installation position of the exhaust pipe, and the sleeved connection between the exhaust pipe and the exhaust pipe helps to fix the exhaust pipe, achieving a more stable fixation effect, reducing installation difficulty, and preventing oil fumes from leaking from the abutment point of the exhaust pipe 2 and the exhaust pipe 13, resulting in better exhaust performance. In this embodiment, the inlet 21 of the exhaust pipe 2 and the exhaust port 12 of the exhaust pipe 13 are fixed by the exhaust port 12 of the exhaust pipe 13 extending into the inlet 21 of the exhaust pipe 2 and being sleeved. In other embodiments, the inlet 21 of the exhaust pipe 2 can also be fixed by extending into the exhaust port 12 of the exhaust pipe 13, as long as the exhaust pipe 2 and the exhaust pipe 13 can be tightly attached.

[0037] Furthermore, such as Figure 3 As shown, the pipe body 24 is provided with a reinforcing rib 241. The reinforcing rib 241 is located inside the pipe body 24 and protrudes from the inner wall of the pipe body 24. The extending direction of the reinforcing rib 241 is the same as the extending direction of the pipe body 24. The reinforcing rib 241 can strengthen the smoke exhaust channel 23, thereby improving the structural strength of the pipe body 24.

[0038] like Figure 4As shown, at least one convection port 242 is provided on the side wall of the exhaust pipe 2, and the convection port 242 is connected to the exhaust channel 23. When the exhaust pipe 2 is working, since the gas inside the convection port 242 is high-temperature gas generated during the heating of food, the gas temperature inside the exhaust channel 23 is higher, the pressure is lower, and the flow rate is faster than the gas outside the convection port 242. Therefore, near the convection port 242, the air pressure inside the pipe body 24 is lower than the air pressure outside the pipe body 24. The gas outside the pipe body 24 will enter the exhaust channel 23 through the convection port 242 due to the pressure difference. Then, since the rate of gas flowing out of the exhaust channel 23 is constant, but some of the gas flowing out of the exhaust channel 23 comes from the air outside the convection port 242, the amount of high-temperature gas flowing out of the exhaust channel 23 in the same amount of time is reduced, the rate at which heat is carried away from the heating space 11 is reduced, and the heat loss from the heating space 11 in the same amount of time is reduced, thereby slowing down the temperature drop in the heating space 11.

[0039] like Figure 1 As shown, the furnace body 1 includes a furnace base 14, a furnace cover 15, and a heating element. The furnace cover 15 is pivotally connected to the furnace base 14, and the furnace cover 15 covers the furnace base 14. The furnace cover 15 and the furnace base 14 enclose and form the heating space 11. The heating element is disposed within the heating space 11 and is fixedly connected to the furnace base 14. The flue pipe 13 is disposed on the furnace cover 15 and can rotate with the furnace cover 15. The furnace cover 15 is rotatably connected to the furnace base 14, and the furnace cover 15 can be rotated open and closed, forming the heating space 11 with the furnace base 14. The flue pipe 2 is disposed on the furnace cover 15 and can move with the furnace cover 15 as the furnace cover 15 rotates, without obstructing the rotation of the furnace cover 15.

[0040] The advantages of this application are that it occupies little space and the heating space 11 cools down slowly. It is also easy to disassemble and assemble, which can reduce the volume of the electric oven after storage, and ensure the stability of smoke exhaust and the convenience of installation.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
