Description

Technical Field

[0001] This utility model relates to the field of oven technology, and more specifically, to an oven. Background Technology

[0002] As people's living standards improve, ovens are becoming increasingly common in home kitchens. Ovens are a common kitchen appliance used for baking, roasting, and other cooking operations. They can make bread, cakes, cookies, and other baked goods, as well as roast meats and vegetables, creating dishes like roasted meat, chicken wings, and vegetables.

[0003] However, existing ovens have the following problems when in use:

[0004] Traditional ovens currently on the market have several shortcomings. Firstly, their heat dissipation structures are simple, mostly relying on a few vents on the outer shell for passive cooling. This causes heat to accumulate inside the oven, shortening the lifespan of electronic and heating components and posing safety hazards such as fires caused by high temperatures. Secondly, the trays are fixed in their installation method, lacking flexibility and making it difficult to adjust their position and quantity to accommodate different sizes and quantities of food, thus limiting the effective use of the oven's internal space. Thirdly, the tray design is often flawed, with a closed bottom that obstructs hot air circulation, preventing even heating of food and leading to uneven heating, resulting in some areas being burnt while others are undercooked, thus affecting the quality of the baked goods.

[0005] This invention utilizes a combination of structures such as a sliding groove, a ventilation groove, and an intake fan to achieve flexible tray adjustment and even heating of food. At the same time, it constructs an efficient heat dissipation and circulation system to quickly dissipate heat and prevent internal overheating. This not only improves baking results and ease of use but also extends the oven's lifespan and reduces safety hazards. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and to provide an oven.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an oven, comprising: a box body, a tray slidably connected inside the box body, a heat-conducting plate fixedly installed on one side inside the box body, an inner cavity opened inside the box body, a heating cavity opened inside the inner cavity, the inner cavity and the heating cavity having a double-layer structure, forming a heat dissipation cavity between them, and three sliding grooves opened at both the left and right ends inside the heating cavity, the sliding grooves being slidably connected to the tray.

[0008] A further preferred embodiment: the front hinge of the box body is connected to the box door, the front of the box door is fixedly installed with a handle, and a knob is opened on the front of the box body, the knob being opened on one side of the box door.

[0009] A further preferred embodiment: the right end of the enclosure has several heat dissipation holes, and the left end of the enclosure is fixedly equipped with an intake fan.

[0010] A further preferred embodiment: sliders are fixedly installed at both ends of the tray, the sliders are slidably connected to the slide grooves, and several ventilation slots are opened at the bottom of the tray.

[0011] A further preferred embodiment: the heat-conducting plate is fixedly installed on the right side of the heating cavity and located between the heating cavity and the inner cavity; an exhaust fan is embedded in the middle of the heat-conducting plate; a heat dissipation fin is fixedly installed on the left end of the heat-conducting plate; and the other end of the heat dissipation fin is fixedly connected to the heating cavity.

[0012] A further preferred embodiment: the heat dissipation fins are arranged in a wavy shape.

[0013] Beneficial effects:

[0014] 1. By incorporating an intake fan, an exhaust fan, heat dissipation holes, and heat dissipation fins, the intake fan actively draws in outside cold air into the heat dissipation cavity formed by the double-layer structure of the inner cavity and the heating cavity, increasing the amount of cold air entering. As the cold air flows within the cavity, it comes into full contact with the heat-conducting plate and the wave-shaped heat dissipation fins. The wave-shaped design greatly increases the heat dissipation area, enabling the cold air to efficiently absorb heat. Subsequently, the exhaust fan accelerates the exhaust of the heated air after it has absorbed heat, and it is discharged into the external environment through the heat dissipation holes, forming a complete and efficient air circulation heat dissipation channel. This structural design allows the air in the heat dissipation cavity to flow rapidly, greatly improving heat dissipation efficiency and enabling the excess heat in the heating cavity to be dissipated more quickly and effectively, preventing heat from accumulating inside the oven. This effectively extends the service life of the electronic components and heating elements inside the oven and reduces the risk of safety accidents such as fires caused by high temperatures.

[0015] 2. The oven features sliding grooves located at both ends of the heating chamber, precisely matching the sliders at both ends of the tray. This allows the tray to slide in and out easily, making installation and disassembly very convenient. Multiple grooves provide different height mounting positions for the tray, allowing users to freely adjust the number and position of trays based on the quantity, size, and type of food being baked. When baking multiple layers of small food items, multiple trays can be installed to fully utilize the space; when baking large food items, the number of trays can be reduced and their positions adjusted to ensure ample baking space. Furthermore, the tray slides stably on the grooves, preventing shaking and displacement during baking, ensuring optimal baking results and effectively improving the oven's practicality and user experience.

[0016] 3. By incorporating ventilation slots, the ventilation slots at the bottom of the tray break the traditional barrier of hot air, allowing hot air in the oven's heating cavity to circulate freely above and below the tray. During baking, the hot air is no longer confined to the top of the tray but can contact the food from all directions, preventing uneven heating that could result in some parts being burnt or others being undercooked. Whether it's a large item or food placed in multiple layers, the ventilation slots ensure that every part reaches the ideal baking state, greatly improving the quality and taste of the baked food and allowing users to easily achieve more satisfactory cooking results.

[0017] 4. In summary, this type of oven, with its structure including sliding tracks, ventilation slots, an intake fan, an exhaust fan, heat dissipation holes, and heat dissipation fins, allows for convenient installation and removal of the trays, with flexible adjustments to their position and number, fully utilizing the oven's internal space. The ventilation slots allow hot air to freely circulate above and below the trays, comprehensively enveloping the food and ensuring even baking, thus improving food quality. The intake fan, exhaust fan, heat dissipation holes, and wave-shaped heat dissipation fins create a highly efficient heat dissipation circulation system. Cool air is introduced by the intake fan, undergoes thorough heat exchange with the heat dissipation fins, and is then rapidly expelled through the heat dissipation holes by the exhaust fan, quickly removing heat and preventing excessive internal temperature, extending the oven's lifespan, and reducing safety hazards. The synergistic effect of these multiple structures makes this oven far superior to traditional ovens in terms of practicality, safety, and baking results, providing users with a superior cooking experience.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-3In this embodiment of the present invention, an oven includes: a cabinet 1, a tray 2 slidably connected inside the cabinet 1, a heat-conducting plate 3 fixedly installed on one side inside the cabinet 1, an inner cavity 105 inside the cabinet 1, a heating cavity 106 inside the inner cavity 105, the inner cavity 105 and the heating cavity 106 having a double-layer structure forming a heat dissipation cavity, three sliding grooves 107 on both the left and right ends of the heating cavity 106, the sliding grooves 107 being slidably connected to the tray 2, a door 101 hinged to the front of the cabinet 1, a handle 102 fixedly installed on the front of the door 101, a knob 104 on the front of the cabinet 1 located on one side of the door 101, and the heat-conducting plate 3 fixedly installed in the heating cavity. Located on the right side of 106, between the heating cavity 106 and the inner cavity 105, when the user starts the oven, the heating temperature and time are set via knob 104. The heating element inside the heating cavity 106 then starts working, generating a large amount of heat. Part of the heat is directly used to heat the food placed on the tray 2, and the other part of the heat is conducted through the heat-conducting plate 3 to the heat dissipation cavity formed by the double-layer structure of the inner cavity 105 and the heating cavity 106. When placing food, the user can open the oven door 101 via the handle 102, slide the tray 2 into the heating cavity 106 along the sliding grooves 107 at both ends inside the heating cavity 106, adjust the position of the tray 2 according to the baking requirements, and then close the oven door 101. During oven operation, heat continuously accumulates within the heat dissipation cavity. The heat dissipation design of the oven body 1 allows this heat to dissipate into the external environment, ensuring the oven's internal temperature remains within a reasonable range. This prevents excessive heat from affecting the oven's lifespan or causing safety hazards. Once the set time is reached, the oven stops operating. The user opens the door 101, slides the tray 2 along the slide 107, and removes the food. The double-layer structure of the inner cavity 105 and the heating cavity 106 forms a heat dissipation cavity. Combined with the heat-conducting plate 3, excess heat from the heating cavity 106 is transferred to the heat dissipation cavity, expanding the space and path for heat dissipation. Compared to traditional single-layer ovens that rely solely on external ventilation holes for heat dissipation, this design dissipates heat more quickly and effectively. To prevent heat buildup inside the oven and extend the lifespan of internal electronic components and heating elements, the oven also reduces the risk of fires caused by high temperatures. Multiple sliding grooves 107 on both sides of the heating cavity 106 allow the trays 2 to slide flexibly in different positions. Users can freely adjust the number and position of the trays 2 according to the volume and quantity of food being baked and their baking needs. For example, when baking multi-layered cookies, multiple trays 2 can be installed on the sliding grooves 107 at different heights to fully utilize the oven's internal space. When baking larger foods, the number of trays 2 can be reduced to provide ample baking space, improving the oven's practicality and ease of use.

[0024] In this embodiment of the invention, a plurality of heat dissipation holes 103 are provided on the right end of the housing 1, an intake fan 108 is fixedly installed on the left end of the housing 1, an exhaust fan 301 is embedded in the middle of the heat-conducting plate 3, and heat dissipation fins 302 are fixedly installed on the left end of the heat-conducting plate 3. The other end of the heat dissipation fins 302 is fixedly connected to the heating cavity 106. The heat dissipation fins 302 are arranged in a wavy shape. When the oven is running, the intake fan 108 fixedly installed on the left end of the housing 1 starts to work, drawing in cold air from the outside into the heat dissipation cavity. During the flow of the cold air in the heat dissipation cavity, it comes into full contact with the heat-conducting plate 3 and the wavy heat dissipation fins 302, absorbing heat. The exhaust fan 301 embedded in the middle of the heat-conducting plate 3 accelerates the exhaust of the hot air after absorbing heat. The hot air is exhausted into the outside environment through the plurality of heat dissipation holes 103 on the right end of the housing 1, forming an air circulation flow that continuously carries away the heat in the heat dissipation cavity. Throughout the entire working process, this air circulation heat dissipation mechanism ensures that the internal temperature of the oven remains within a reasonable range. Within a reasonable range, to avoid affecting the oven's lifespan or causing safety hazards due to excessive temperature, the oven stops working after the set time is reached. The user opens the oven door 101, slides the tray 2 out along the slide 107 to remove the food. The left and right ends of the oven body 1 are respectively equipped with an intake fan 108 and a heat dissipation hole 103, which, together with the exhaust fan 301 on the heat conduction plate 3, form a complete air circulation heat dissipation channel. The intake fan 108 actively sends in cool air, while the exhaust fan 301 and heat dissipation hole 103 accelerate the discharge of hot air, making the air in the heat dissipation cavity flow rapidly and greatly improving the heat dissipation efficiency. At the same time, the wavy heat dissipation fins 302 on the heat conduction plate 3 greatly increase the contact area with the air, further enhancing the heat exchange capacity, and can more quickly and effectively dissipate excess heat in the heating cavity 106, effectively preventing heat accumulation inside the oven, extending the lifespan of the electronic components and heating elements inside the oven, and reducing the risk of safety accidents such as fires caused by high temperatures.

[0025] In this embodiment of the utility model, sliders 201 are fixedly installed at both ends of the tray 2. The sliders 201 are slidably connected to the slide grooves 107. Several ventilation slots 202 are opened at the bottom of the tray 2. During the operation of the oven, the hot air in the heating cavity 106 can circulate freely above and below the tray 2 through the ventilation slots 202, so that the food can be heated evenly. This breaks the barrier of the tray to the hot air, allowing the hot air to move freely above and below the tray and come into contact with the food in all directions. This avoids the situation where the food is partially burnt or partially undercooked, ensures that the food is heated evenly, and improves the quality and taste of the baked food.

[0026] Working principle: The user sets the oven's heating temperature and operating time using the knob 104 located on the side of the oven door 101 on the front of the oven body 1, according to baking needs. At this time, the oven is in standby mode, awaiting the start command. Simultaneously, the user can open the oven door 101 using the handle 102 on the front of the door. Since the sliders 201 fixedly installed at both ends of the tray 2 are compatible with the three sliding grooves 107 at both ends of the heating cavity 106, the user can easily slide the tray 2 into the heating cavity 106 along the sliding grooves 107. The number and position of the trays 2 can be flexibly adjusted according to the volume and quantity of the food. For example, when baking multi-layered cookies, multiple trays 2 can be installed on sliding grooves 107 at different heights; when baking large pieces of food, the number of trays 2 can be reduced. After adjustment... When the oven door 101 is closed and the user starts the oven, the heating element inside the heating cavity 106 begins to work, generating a large amount of heat. This heat is divided into two parts: one part directly heats the food placed on the tray 2 to meet the heat requirements for baking; the other part of the heat is conducted through the heat-conducting plate 3, which is fixedly installed on the right side of the heating cavity 106 and located between the heating cavity 106 and the inner cavity 105, to the heat dissipation cavity formed by the double-layer structure of the inner cavity 105 and the heating cavity 106. The good thermal conductivity of the heat-conducting plate 3 ensures that the heat can be transferred efficiently and avoids excessive heat accumulation in the heating cavity 106. At the same time as the heat is conducted to the heat dissipation cavity, the heat dissipation system starts to operate, and the intake fan 108 fixedly installed on the left side of the oven body 1 starts to ventilate the oven. As cold air flows through the heat dissipation cavity, it comes into full contact with the heat-conducting plate 3 and the wavy heat dissipation fins 302. The wavy heat dissipation fins 302 significantly increase the contact area with the air, allowing the cold air to absorb heat more efficiently and become hot air. Subsequently, the exhaust fan 301 embedded in the middle of the heat-conducting plate 3 accelerates the exhaust of the hot air. The hot air is then exhausted into the external environment through several heat dissipation holes 103 on the right end of the housing 1, forming a complete air circulation path. The intake fan 108, exhaust fan 301, heat dissipation holes 103, and heat dissipation fins 302 work together to continuously remove heat from the heat dissipation cavity, ensuring that the internal temperature of the oven remains within a reasonable range and preventing damage to the oven interior due to high temperatures. To prevent damage to electronic components and heating elements and reduce safety hazards, several ventilation slots 202 at the bottom of the tray 2 play an important role during oven operation. Hot air in the heating cavity 106 can circulate freely up and down the tray 2 through the ventilation slots 202, breaking the barrier of the tray 2 to hot air and allowing hot air to come into contact with the food from all directions. In this way, the food can be heated evenly, effectively avoiding local burning or undercooking, and ensuring the quality and taste of the baked food. When the working time set by the user through the knob 104 is reached, the oven stops working. At this time, the user opens the oven door 101 again through the handle 102, slides the tray 2 out along the slide 107, and takes out the baked food, completing the entire baking process.
