Description

Technical Field

[0001] This utility model relates to the field of electric oven technology, specifically an electric oven with a rapid surface cooling structure. Background Technology

[0002] With the continuous improvement of people's living standards and the diversification of cooking needs, electric ovens have gradually become an indispensable cooking appliance in home and commercial kitchens. Electric ovens, with their high efficiency, convenience, and safety, are widely used in various cooking processes such as baking, grilling, and food heating. However, most electric ovens on the market currently have some common problems during use, mainly concerning safety and cooling efficiency.

[0003] On the one hand, the surface temperature of traditional electric ovens is usually very high after baking at high temperatures. This not only makes users prone to burns when removing food and performing other operations, but also poses a potential threat to the safety of the kitchen environment. This problem is particularly prominent in households with elderly people and children.

[0004] On the other hand, the cooling process of existing electric ovens is relatively slow. After an electric oven completes a baking task, it usually requires a long time to cool down before it can be used again. This not only affects the utilization efficiency of the equipment, but is also particularly inconvenient when multiple baking tasks need to be performed consecutively. Some users even resort to external manual methods such as using fans to accelerate cooling, which is not only troublesome and ineffective, but also poses certain safety hazards. In view of this, we propose an electric oven with a surface rapid cooling structure. Utility Model Content

[0005] The purpose of this invention is to provide an electric oven with a rapid surface cooling structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric oven with a rapid surface cooling structure includes an oven body and is a main device for baking, grilling, and other functions. It is used to hold and heat food and is a mature existing technology, so it will not be described in detail here. The upper and lower sides of the oven body are provided with first heat-conducting plates for conducting heat. The opposing sides of the two first heat-conducting plates are provided with multiple first heat dissipation fins to increase the heat dissipation area and accelerate heat dissipation. The left and right sides of the oven body are provided with second heat-conducting plates for conducting heat. The opposing sides of the two second heat-conducting plates are provided with multiple second heat dissipation fins to increase the heat dissipation area and accelerate heat dissipation.

[0008] The electric oven body is provided with a heat dissipation cover on the outside of the electric oven body. It is located on the outside of the electric oven body to protect the internal components and assist in heat dissipation. The bottom of the heat dissipation cover has multiple air inlets, and the top of the heat dissipation cover has two air outlets arranged symmetrically on the left and right. Outside air enters into the heat dissipation cover through the multiple air inlets, and the heat inside the heat dissipation cover is discharged from the air outlets with the airflow.

[0009] The top of the heat dissipation cover is equipped with heat dissipation components at the two air outlets to efficiently expel hot air from inside the heat dissipation cover. Each heat dissipation component includes a rectangular tube fixedly connected to the top of the heat dissipation cover. A fan is installed inside the rectangular tube and is powered by an external power source. When the fan is working, it expels the air from inside the heat dissipation cover, thereby allowing outside air to enter the heat dissipation cover through multiple air inlets. The heat inside the heat dissipation cover enters the rectangular tube through the air outlets and is then expelled.

[0010] Preferably, a thermostat and a temperature sensor are provided on the front side and near the top of the electric oven body. The temperature sensor and the fan are electrically connected to the thermostat via wires. The temperature sensor is used to collect temperature data and feed it back to the thermostat. The thermostat is used to control the start and stop of the fan. When the temperature sensor detects that the temperature of the surface of the electric oven body reaches the set threshold, the thermostat controls the fan to turn on, thereby generating airflow in the heat dissipation shroud to quickly dissipate the heat from the surface of the electric oven body. When the temperature sensor detects that the temperature of the surface of the electric oven body is lower than the set threshold, the thermostat controls the fan to turn off.

[0011] Preferably, the heat dissipation cover is provided with feet at the bottom and near the four corners, and the bottom of the heat dissipation cover is also provided with a dustproof component. The feet support the heat dissipation cover and provide installation space for the dustproof component.

[0012] Preferably, the dustproof component includes two L-shaped limiting plates arranged symmetrically on the left and right. The top of the L-shaped limiting plates is fixedly connected to the bottom of the heat dissipation cover. A first frame plate and a second frame plate are provided between the two L-shaped limiting plates. The L-shaped limiting plates play a positioning role for the first frame plate and the second frame plate, which facilitates the assembly and disassembly of the first frame plate and the second frame plate.

[0013] Preferably, the first frame plate is provided with a first filter screen, and the second frame plate is provided with a second filter screen. The filter pore size of the first filter screen is larger than that of the second filter screen, so that the air entering the heat dissipation cover is filtered twice to prevent dust from adhering to the surface of the first heat conduction plate, the first heat dissipation fin, the second heat conduction plate, and the second heat dissipation fin, thus ensuring the heat conduction effect.

[0014] Preferably, the first frame plate has rectangular insertion holes at the top and near the left and right sides, and the second frame plate has rectangular insertion blocks at the bottom and near the left and right sides. The two rectangular insertion blocks are respectively inserted into the two rectangular insertion holes, so that the first frame plate and the second frame plate can be connected together, which facilitates simultaneous assembly and disassembly.

[0015] Preferably, the rear end of the inner side of the L-shaped limiting plate is provided with a rear stop block, and the rear sides of the first frame plate and the second frame plate abut against the front side of the rear stop block, which facilitates the workers to quickly install the first frame plate and the second frame plate.

[0016] Preferably, the top of the inner wall of the rectangular tube is provided with an installation groove, in which a dustproof mesh plate is placed to prevent dust from falling into the rectangular tube. Finger grooves are provided in the middle of the left and right sides of the top of the rectangular tube to facilitate the removal of the dustproof mesh plate by the staff, thereby making it convenient to clean the dustproof mesh plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This electric oven with a rapid surface cooling structure, through the first heat-conducting plate, the first heat dissipation fins, the second heat-conducting plate and the second heat dissipation fins set on the oven body, utilizes the synergistic effect of the heat-conducting plate and the heat dissipation fins to quickly transfer heat, thereby effectively reducing the temperature of the oven surface and reducing the risk of burns when users take out food and perform other operations. It is especially suitable for families with elderly people and children, and improves the safety of use.

[0019] 2. This electric oven with a rapid surface cooling structure can generate effective airflow through the air inlet and outlet holes on the heat dissipation shroud and the fan installed inside the rectangular tube. This accelerates the discharge of hot air from inside the heat dissipation shroud, significantly shortens the cooling time of the electric oven after completing the baking task, thereby improving equipment utilization efficiency and facilitating users to perform multiple consecutive baking operations.

[0020] 3. This electric oven with a rapid surface cooling structure monitors the temperature data of the oven body surface in real time through a temperature sensor and feeds it back to the thermostat. When the temperature reaches the set threshold, the thermostat automatically controls the fan to start and quickly reduce the surface temperature. When the temperature drops below the set threshold, the thermostat automatically turns off the fan to save energy and achieve intelligent and automated temperature control management.

[0021] 4. The electric oven with a rapid surface cooling structure has a dustproof component at the bottom of the heat dissipation cover, which can filter the air entering the heat dissipation cover twice to prevent dust from adhering to the surface of the heat conduction plate and heat dissipation fins, thereby ensuring good heat conduction and heat dissipation. At the same time, the dustproof component is easy to clean and maintain, extending the service life of the equipment. Attached Figure Description

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] An electric oven with a rapid surface cooling structure includes an oven body 1, which is the main equipment for baking, grilling and other functions, used to hold and heat food. This is an existing mature technology and will not be described in detail here. The upper and lower sides of the oven body 1 are provided with first heat-conducting plates 3 for conducting heat. The opposite sides of the two first heat-conducting plates 3 are provided with multiple first heat dissipation fins 30 to increase the heat dissipation area and accelerate heat dissipation. The left and right sides of the oven body 1 are provided with second heat-conducting plates 4 for conducting heat. The opposite sides of the two second heat-conducting plates 4 are provided with multiple second heat dissipation fins 40 to increase the heat dissipation area and accelerate heat dissipation.

[0033] The outer side of the electric oven body 1 is provided with a heat dissipation cover 2, which is located on the outside of the electric oven body 1 to protect the internal components and assist in heat dissipation. The bottom of the heat dissipation cover 2 is provided with multiple air inlets 20, and the top of the heat dissipation cover 2 is provided with two air outlets 21 arranged symmetrically from left to right. Outside air enters into the heat dissipation cover 2 through the multiple air inlets 20, and the heat inside the heat dissipation cover 2 is discharged from the air outlets 21 with the airflow.

[0034] The top of the heat dissipation cover 2 is provided with heat dissipation components 5 at the positions of the two air outlets 21. These components are used to efficiently dissipate the hot air inside the heat dissipation cover 2. Each heat dissipation component 5 includes a rectangular tube 50 fixedly connected to the top of the heat dissipation cover 2. A fan 51 is installed inside the rectangular tube 50. The fan 51 is powered by an external power source. When the fan 51 is working, it dissipates the air inside the heat dissipation cover 2, thereby allowing outside air to enter the heat dissipation cover 2 through multiple air inlets 20. The heat inside the heat dissipation cover 2 enters the rectangular tube 50 through the air outlets 21 and is then discharged.

[0035] In this embodiment, a thermostat 6 and a temperature sensor 7 are provided on the front side and near the top of the electric oven body 1. The temperature sensor 7 and the fan 51 are electrically connected to the thermostat 6 through wires. The temperature sensor 7 is used to collect temperature data and feed it back to the thermostat 6. The thermostat 6 is used to control the start and stop of the fan 51. When the temperature sensor 7 detects that the temperature of the surface of the electric oven body 1 reaches the set threshold, the thermostat 6 controls the fan 51 to turn on, thereby generating airflow in the heat dissipation cover 2 to quickly dissipate the heat from the surface of the electric oven body 1. When the temperature sensor 7 detects that the temperature of the surface of the electric oven body 1 is lower than the set threshold, the thermostat 6 controls the fan 51 to turn off.

[0036] Specifically, the heat dissipation cover 2 has support feet 22 at the bottom and near the four corners. The bottom of the heat dissipation cover 2 also has a dustproof component 8. The support feet 22 support the heat dissipation cover 2 and provide installation space for the dustproof component 8.

[0037] Furthermore, the dustproof component 8 includes two L-shaped limiting plates 80 arranged symmetrically on the left and right. The top of the L-shaped limiting plate 80 is fixedly connected to the bottom of the heat dissipation cover 2. A first frame plate 81 and a second frame plate 82 are provided between the two L-shaped limiting plates 80. The L-shaped limiting plates 80 play a positioning role for the first frame plate 81 and the second frame plate 82, which facilitates the assembly and disassembly of the first frame plate 81 and the second frame plate 82.

[0038] Furthermore, a first filter screen 810 is provided inside the first frame plate 81, and a second filter screen 820 is provided inside the second frame plate 82. The filter hole size of the first filter screen 810 is larger than that of the second filter screen 820, so that the air entering the heat dissipation cover 2 is filtered twice to prevent dust from adhering to the surface of the first heat conduction plate 3, the first heat dissipation fin 30, the second heat conduction plate 4, and the second heat dissipation fin 40, thus ensuring the heat conduction effect.

[0039] Furthermore, rectangular insertion holes 811 are provided on the top of the first frame plate 81 and near the left and right sides, and rectangular insertion blocks 821 are provided on the bottom of the second frame plate 82 and near the left and right sides. The two rectangular insertion blocks 821 are respectively inserted into the two rectangular insertion holes 811, so that the first frame plate 81 and the second frame plate 82 can be connected, which facilitates simultaneous assembly and disassembly.

[0040] Furthermore, a rear stop block 83 is provided at the rear end of the inner side of the L-shaped limiting plate 80, and the rear sides of the first frame plate 81 and the second frame plate 82 abut against the front side of the rear stop block 83, which facilitates the quick installation of the first frame plate 81 and the second frame plate 82 by the staff.

[0041] Furthermore, an installation groove 500 is provided at the top of the inner wall of the rectangular tube 50, and a dustproof mesh plate 52 is placed in the installation groove 500 to prevent dust from falling into the rectangular tube 50. Finger grooves 501 are provided in the middle of the left and right sides of the top of the rectangular tube 50 to facilitate the removal of the dustproof mesh plate 52 by the staff, thereby making it convenient to clean the dustproof mesh plate 52.

[0042] In this embodiment, the electric oven with a rapid surface cooling structure is used as follows: First, ensure that the oven body 1 is correctly installed and connected to the power supply. Adjust the baking temperature of the oven body 1 according to the needs of the food. During baking, the first heat-conducting plate 3 and the second heat-conducting plate 4 transfer the surface temperature of the oven body 1. The temperature sensor 7 monitors the surface temperature of the oven body 1 in real time. When the temperature sensor 7 detects that the surface temperature of the oven body 1 reaches the set threshold, the thermostat 6 automatically starts the fan 51. The started fan 51 quickly exhausts the hot air inside the heat dissipation cover 2 through the rectangular tube 50, while outside air enters through the air inlet 20, forming an effective airflow to quickly reduce the surface temperature of the oven body 1. When the temperature sensor 7 detects that the surface temperature of the oven body 1 has dropped below the set threshold, the thermostat 6 will promptly turn off the fan 51, thereby saving energy. The oven body 1 also features a dustproof component. 8. Dust is prevented from entering and adhering to the first heat-conducting plate 3 and the second heat-conducting plate 4 through a double-layer filter, ensuring high heat conduction efficiency of the equipment. Users need to regularly check the dustproof components 8 and dustproof mesh 52. Using the docking design of rectangular insert 821 and rectangular insert 811, users can easily disassemble the first frame plate 81 and the second frame plate 82 to clean the first filter 810 and the second filter 820 to maintain cleanliness. The dustproof mesh 52 can be easily removed through the finger groove 501, which not only facilitates cleaning but also ensures a clean state for the next use, thereby extending the overall service life of the electric oven body 1. Through the above usage steps, the electric oven can effectively improve safety and work efficiency during electric baking, greatly shorten the cooling time, and allow users to quickly carry out the next baking operation. At the same time, intelligent temperature control and fan 51 management enable the equipment to save energy while providing a good user experience.
