Description

Technical Field

[0001] This utility model relates to the field of oven technology, and more specifically, to an oven that facilitates heat dissipation from the inner cavity. Background Technology

[0002] An oven is a sealed appliance used for baking food or drying products. It is divided into household ovens and industrial ovens. Household ovens can be used to process some pasta. Industrial ovens are equipment used in industry to dry products; they can be electric or gas-fired and are also called baking ovens or drying boxes. Electric ovens are electric heating appliances that use the radiant heat emitted by electric heating elements to bake food. They can be used to make roast chicken, roast duck, bread, pastries, etc. Depending on the needs of the food being baked, the temperature of an electric oven can generally be adjusted within the range of 50-250℃.

[0003] Existing ovens tend to accumulate heat directly inside the liner or oven body during use, affecting cooking results and accelerating the aging of electrical components. After long-term use, the heat dissipation channels are easily blocked by dust and debris, further reducing heat dissipation efficiency. In addition, most heat dissipation-related components are fixed connections, making cleaning and replacement inconvenient and increasing maintenance costs.

[0004] This invention can improve heat dissipation efficiency, ensure safe use, and extend the life of the oven. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide an oven that facilitates heat dissipation from the inner cavity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oven that facilitates heat dissipation of the inner cavity, comprising: a cabinet, a hinged flap at the upper end of the cabinet, an inner cavity inside the cabinet, a heat dissipation plate embedded in the side of the cabinet, a heat dissipation groove through the flap, and a cavity between the inner cavity and the cabinet.

[0007] A further preferred embodiment: a sealing block is provided on the inner side of the flip cover, the sealing block is embedded in the cavity, and the flip cover is connected to the box body by a buckle.

[0008] A further preferred embodiment: a heat insulation layer is fixedly installed on the upper end of the inner liner, a heat insulation plate is fixedly installed on the upper end of the heat insulation layer, and a filter screen is embedded inside the heat dissipation groove.

[0009] A further preferred embodiment: a plurality of heat sinks are fixedly installed on the upper end of the heat insulation plate, the heat sinks are evenly distributed, and the heat sinks are located inside the cavity.

[0010] A further preferred embodiment: the side of the housing is provided with a groove, the heat sink can be embedded in the groove, and the heat sink and the groove are detachably connected.

[0011] A further preferred embodiment: the inner wall of the groove is provided with a slot, and the heat sink is surrounded by a sealing strip, which can be embedded in the slot, and the sealing strip and the slot are detachably connected.

[0012] A further preferred embodiment: the sealing strip is made of rubber and is hollow inside; the heat dissipation plate has several heat dissipation holes on its outer side, and a filter screen is installed inside the heat dissipation holes.

[0013] A further preferred embodiment: an exhaust fan is provided on one side of the cavity.

[0014] Beneficial effects:

[0015] 1. The flip-top design features a sealing block that engages within the cavity for stability during use. Furthermore, the through-hole ventilation channels on the flip-top precisely dissipate residual heat, preventing overheating and reducing the risk of burns when opening and closing. Additionally, the flip-top is secured to the oven body with a snap-fit ​​mechanism, further enhancing stability and minimizing the impact of flap movement on the oven's overall structure, thus improving safety and stability. The filter within the ventilation channels prevents dust and food debris from entering the cavity, ensuring long-term effective cooling. When the cavity becomes too hot, the flip-top can be opened to allow the cooling fins to directly contact the air, accelerating cooling and reducing safety risks. After cooling is complete, the flip-top can be closed again without affecting secondary cooling or overall operation.

[0016] 2. The heat dissipation fins play a crucial role in the oven's heat dissipation process, significantly improving heat dissipation efficiency. The fins are evenly fixed to the upper part of the insulation plate and located within the cavity, greatly increasing the contact area with the air inside the cavity. This allows the heat absorbed by the insulation plate to be transferred to the air more efficiently, accelerating the diffusion of heat from the inner cavity to the cavity. When the exhaust fan starts and forms a directional airflow, the airflow passes through the gaps between the fins, quickly carrying away the heat from the fin surface. Combined with the active cooling effect of the exhaust fan, this further accelerates heat removal and shortens the oven's cooling time. Furthermore, the fins disperse heat to different areas of the cavity, preventing localized heat accumulation and ensuring a more even heat distribution. This facilitates the coordinated action of the exhaust fan and the heat dissipation plate to remove heat, reducing the risk of overheating in localized components due to concentrated heat, thereby extending the lifespan of the oven's components.

[0017] 3. By incorporating a cavity, the oven can absorb heat conducted from the inner cavity, acting as a heat buffer layer to prevent heat from directly accumulating inside the inner cavity or oven body. This prevents the inner cavity from overheating and affecting cooking results. It also reduces the direct baking of internal circuit components by heat, slowing down component aging. The cavity provides an effective airflow circulation space for the exhaust fan. When the exhaust fan is activated, it can create directional hot air exhaust and cold air replenishment circulation within the cavity, providing a channel for rapid heat transfer. In addition, the cavity can also accommodate the heat dissipation fins on the heat insulation plate, allowing the heat emitted by the fins to be concentrated here, facilitating the heat dissipation through the heat dissipation plate and other structures, achieving orderly heat conduction and dissipation, and ensuring the efficient operation of the oven's overall heat dissipation system.

[0018] 4. In summary, this oven, which facilitates heat dissipation from the inner cavity, incorporates a structure including heat dissipation fins. The flip-top is positioned by a sealing block, and the heat dissipation channels expel nearby residual heat. A filter screen prevents clogging, while the clips and sealing block ensure stable operation. The heat dissipation fins increase the heat dissipation area, accelerating heat transfer to the cavity. Combined with an exhaust fan, this further speeds up heat dissipation and prevents localized heat accumulation. The cavity acts as a buffer zone, absorbing heat and providing space for airflow circulation. It accommodates the heat dissipation fins and concentrates heat, contributing to efficient heat dissipation. These three elements work together to improve heat dissipation efficiency, ensure safe use, and extend the oven's lifespan. Attached Figure Description

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-5 In this embodiment of the present invention, an oven that facilitates heat dissipation of the inner cavity includes: a body 1, a flip cover 2 hinged to the upper end of the body 1, an inner cavity 3 disposed inside the body 1, a heat dissipation plate 4 embedded in the side of the body 1, a heat dissipation groove 201 extending through the flip cover 2, a cavity 101 disposed between the inner cavity 3 and the body 1; a sealing block 202 disposed inside the flip cover 2, the sealing block 202 being embedded inside the cavity 101, the flip cover 2 being connected to the body 1 by a buckle; and an exhaust fan 5 disposed on one side of the cavity 101.

[0027] When the oven is working, the inner cavity 3 generates a large amount of heat. Some of this heat is conducted through the wall of the inner cavity 3 to the cavity 101 between it and the oven body 1. The cavity 101 acts as a heat buffer layer, preventing heat from directly accumulating inside the inner cavity or oven body 1. When the flip cover 2 is closed, the inner sealing block 202 is embedded in the cavity 101, making the heat more concentrated within the cavity 101, facilitating subsequent directional heat dissipation. At the same time, it further limits and fixes the position of the flip cover 2, making it more stable during use. After the exhaust fan 5 on one side of the cavity 101 is started... A directional airflow is formed to quickly extract the high-temperature air from cavity 101, while simultaneously drawing in cooler air from outside the oven body 1 through the heat dissipation plate 4 or gaps, accelerating the release of heat from the inner liner. The heat dissipation plate 4 on the side of the oven body 1 directly contacts cavity 101 and the external environment, dissipating some of the heat from cavity 101 into the air through heat conduction and radiation. The heat dissipation groove 201 of the flip cover 2 is used to exhaust residual heat near the flip cover 2, preventing the flip cover 2 from overheating due to heat accumulation. After the oven stops working, the exhaust fan 5 can... After running for a period of time, the residual heat in the inner liner and cavity 101 is completely discharged through the above cycle, shortening the cooling time. The heat dissipation method using the exhaust fan 5, heat dissipation plate 4, and heat dissipation groove 201 can quickly dissipate the heat from the inner liner, avoiding long-term heat accumulation that could lead to aging of the inner liner and circuit components, thus extending the oven's service life. Timely discharge of heat from the inner liner can prevent aging of internal parts due to poor heat dissipation, reducing problems such as food burning and uneven heating. At the same time, the temperature of the oven body 1 is more stable, preventing the outer shell from overheating and affecting the safety of use. The sealing block 202 reduces disorderly heat leakage and prevents local overheating of the surface of the oven body 1. The heat dissipation groove 201 and heat dissipation plate 4 direct the heat out, reducing the temperature of the flip cover 2 and the outer shell of the oven body 1, making it safer for users to open and close the flip cover 2 or touch the oven body 1. The residual heat is quickly discharged through active and passive heat dissipation, allowing the oven to cool down to a safe temperature more quickly, making it convenient for users to remove food and clean the inner liner in time. The sealing block 202 further limits the flip cover 2, making it more stable during use and reducing the impact of the flip cover 2's instability on the device.

[0028] In this embodiment of the present invention, a heat insulation layer 301 is fixedly installed on the upper end of the inner liner 3, and a heat insulation plate 302 is fixedly installed on the upper end of the heat insulation layer 301. A filter screen is embedded inside the heat dissipation groove 201. Several heat dissipation fins 303 are fixedly installed on the upper end of the heat insulation plate 302. The heat dissipation fins 303 are evenly distributed and located inside the cavity 101. A groove 102 is opened on the side of the box 1. The heat dissipation plate 4 can be embedded inside the groove 102, and the heat dissipation plate 4 and the groove 102 are detachably connected. A slot 103 is opened around the inner wall of the groove 102. A sealing strip 401 is arranged around the heat dissipation plate 4. The sealing strip 401 can be embedded inside the slot 103, and the sealing strip 401 and the slot 103 are detachably connected. The sealing strip 401 is made of rubber and is hollow inside. Several heat dissipation holes 402 are opened on the outer side of the heat dissipation plate 4, and a filter screen is installed inside the heat dissipation holes 402.

[0029] The heat insulation layer 301 at the upper end of the inner liner 3 prevents heat from directly diffusing upwards to the flip cover 2, directing the heat to other sides of the inner liner. The heat insulation plate 302 is fixed to the upper end of the heat insulation layer 301, on the one hand absorbing a small amount of heat that penetrates the heat insulation layer 301, and on the other hand dispersing the heat into the cavity 101 through the uniform heat dissipation fins 303 on its surface. The heat dissipation fins 303 increase the contact area with the air in the cavity 101, making the heat transfer to the air more efficient, facilitating the exhaust fan 5 and heat dissipation plate 4 to exhaust the heat. The heat dissipation fins 303 are evenly distributed on the upper end of the heat insulation plate 302. When the exhaust fan 5 is started, the airflow passes through the gaps between the heat dissipation fins 303, carrying away the heat on the surface of the heat dissipation fins 303. At the same time, the heat dissipation fins 303 can release heat into the cavity 101 through thermal radiation. Combined with the airflow circulation of the exhaust fan 5, the heat transfer efficiency from the inner liner to the cavity 101 is further improved. The filter screen prevents impurities from entering, ensuring... The heat dissipation channel is unobstructed, filtering dust and food debris from the air to prevent impurities from entering the cavity 101 or the inner liner, preventing blockage of the heat dissipation slot 201, filtering external dust and insects to prevent them from entering the cavity 101 through the heat dissipation hole 402, and preventing dust accumulation from affecting the operation of the exhaust fan 5. When the heat dissipation plate 4 is embedded in the groove 102, the hollow rubber sealing strip 401 around it is squeezed and embedded in the slot 103. The elasticity of the rubber fills the gaps, preventing the disorderly leakage of high-temperature air in the cavity 101 from the gaps and preventing external dust from entering the cavity 101 from the gaps. The sealing strip 401 and the slot 103, and the heat dissipation plate 4 and the groove 102 are all detachable. When the heat dissipation plate 4 is dusty or the sealing strip 401 is aged, it can be easily disassembled for cleaning and replacement, avoiding a decrease in heat dissipation efficiency after long-term use. The hollow rubber sealing strip 401 has better elasticity than the solid sealing strip 401 and can fit the slot 103 more tightly.Meanwhile, the rubber material is heat-resistant and has poor thermal conductivity, so it will not age rapidly due to contact with hot air, nor will it conduct heat from the cavity 101 to the outside of the cabinet 1 through the sealing strip 401. The heat insulation layer 301 and the heat insulation plate 302 prevent the heat from the inner liner from ineffectively diffusing to the flip cover 2, and concentrate the heat to the heat sink 303 and the cavity 101. With the help of the exhaust fan 5, it avoids the inefficiency caused by scattered heat dissipation. The heat sink 303 increases the heat dissipation area, allowing the heat from the inner liner to be transferred to the air in the cavity 101 more quickly, accelerating the active and passive heat dissipation cycle and further shortening the cooling time. The filters of the heat dissipation groove 201 and the heat dissipation hole 402 directly block impurities from entering, preventing the heat dissipation channel from being blocked by dust accumulation, thus solving the problem of traditional The issue of slow heat dissipation after prolonged oven use is addressed by extending the effective lifespan of the heat dissipation system. The hollow rubber sealing strip 401, through its elastic seal, reduces heat leakage from the gaps between the heat dissipation plate 4 and the groove 102, lowering the risk of localized high temperatures on the outer shell of the oven body 1 caused by heat leakage through these gaps. Heat is concentrated within the cavity 101 and directionally dissipated, reducing ineffective leakage and indirectly lowering the energy consumption of the oven when maintaining the set temperature. The heat dissipation plate 4 and sealing strip 401 are removable, allowing users to periodically clean the filter, wipe the heat dissipation plate 4, or replace worn sealing strip 401. Maintenance requires no special tools, reducing future repair costs and ensuring the oven maintains efficient heat dissipation for extended periods, thus improving the overall structural durability.

[0030] Working principle: When the oven is working, some of the heat generated by the inner cavity 3 is conducted through the wall to the cavity 101 between it and the oven body 1. When the flip cover 2 is closed, the inner sealing block 202 is embedded in the cavity 101 to reduce disordered heat leakage, so that the heat is concentrated in the cavity 101. The exhaust fan 5 on one side of the cavity 101 starts to form a directional airflow, which draws out the high-temperature air and at the same time drives the external cold air into the heat dissipation plate 4 to accelerate the heat release. The heat dissipation plate 4 on the side of the oven body 1 dissipates heat through heat conduction and radiation, while the heat dissipation groove 201 of the flip cover 2 discharges the residual heat nearby. The heat insulation layer 301 at the upper end of the inner cavity 3 prevents heat from spreading upward to the flip cover 2 and directs the heat to other sides. 02 Receives a small amount of heat that penetrates the insulation layer 301 and disperses the heat to the cavity 101 through the evenly distributed heat sink 303 at the top, increasing the contact area with the air for efficient heat transfer. The filter screens in the heat sink 201 and the heat sink 4 heat sink hole 402 can block dust and debris from entering, preventing blockage of the heat dissipation channel. When the heat sink 4 is embedded in the side groove 102 of the cabinet 1, the surrounding rubber hollow sealing strip 401 is squeezed into the slot 103, using elastic sealing gaps to prevent heat leakage and external dust from entering. Both the sealing strip 401 and the heat sink 4 are detachable for easy cleaning and replacement. After the oven stops working, the exhaust fan 5 can continue to run to completely exhaust the residual heat.
