A roaster with good heat insulation effect and not easy to scald

Abstract

This utility model discloses a grill with good heat insulation and low risk of burns, relating to the field of grill technology. The utility model includes a shell, a grilling mesh on the top of the shell, a charcoal mesh inside the shell, heat insulation components fixedly connected to the front and rear sides of the shell, and a discharge assembly at the bottom of the shell. The heat insulation components include two heat insulation covers. This utility model utilizes the heat insulation components to create a heat-insulating cavity between the heat insulation covers and the shell. This cavity, along with a heating cover, a conveying pipe, and an exhaust pipe, forms an air circulation channel. External air enters the heating cover through the inner cavity of the heat insulation cover, is heated, and then rises and exits, forming a continuous airflow heat insulation layer. This reduces the surface temperature of the shell, preventing burns to the user. Simultaneously, the heated air delivers combustion-supporting airflow to the charcoal mesh through the exhaust pipe, achieving double-layer heat insulation protection and improving charcoal combustion efficiency. This solves the problem of high surface temperature and easy burns caused by single-layer structures due to rapid heat conduction.

Description

Technical Field

[0001] This utility model belongs to the field of oven technology, and in particular relates to an oven with good heat insulation and that is not easy to burn your hands. Background Technology

[0002] An oven is a device used for cooking food. It heats the internal space to cook the food. It usually has a heat source and heat preservation function and can evenly distribute heat. Ovens are widely used in home kitchens, restaurants and industrial food production. Different types of ovens use different heating methods, such as electric heating or gas heating.

[0003] Current ovens consist of an outer shell, charcoal mesh, grilling rack, legs, and handles. Charcoal is placed on top of the charcoal mesh and ignited, using the high temperature of the burning charcoal to heat the food on top of the grilling rack. However, existing ovens are all single-layer structures, and their outer shells lack heat insulation, resulting in rapid heat conduction. This causes the oven surface to remain at a high temperature for extended periods, making it easy for users to get burned if they accidentally touch the surface, reducing the oven's safety and making it inconvenient to use.

[0004] To address these issues, we have developed an oven with excellent heat insulation that prevents burns. Utility Model Content

[0005] The purpose of this invention is to provide an oven with good heat insulation and that is less likely to burn the user's hands. By combining the heat insulation component and the food discharge component, it solves the problem that existing ovens lack heat insulation and have a single-layer design that leads to rapid heat conduction, making it easy for users to get burned during the baking process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an oven with good heat insulation and low risk of burns.

The heat insulation assembly includes two heat insulation covers, each fixedly connected to the shell on its opposite side. Heating covers are located on both sides of the bottom of the shell's inner cavity, and a conveying pipe connects to the opposite side of each heating cover. The end of the conveying pipe away from the heating cover extends into the inner cavity of the heat insulation cover. An exhaust pipe connects to the top of the heating cover. The discharge assembly includes two base plates, the top of which is movably connected to the heat insulation cover. A fixing rod is fixedly connected to the right side of the base plate, and a fixing mechanism is fixedly connected to the bottom right side of the shell.

The pressure block can squeeze the push block to control the locking rod to compress the spring, the locking rod can fix the fixing rod to prevent the base plate from rotating, and the spring can reset the push block when the locking rod is not squeezed.

[0009] The present invention is further configured such that movable openings for use with the locking rod are provided on the front and rear sides of the bottom of the fixed shell, and a push plate is fixedly connected to the top of the pressure block. The movable openings facilitate the movement of the locking rod, and the push plate facilitates the user to push the pressure block so that the pressure block can squeeze the push block.

[0010] The present invention is further configured such that a handle is movably connected to the side of the heat insulation cover away from the shell, and a heat insulation plate is fixedly connected to the inner wall of the heat insulation cover. The handle allows the user to easily lift the shell and move its position, and the heat insulation plate can increase the heat insulation effect of the heat insulation cover.

[0011] The present invention is further configured such that handles are fixedly connected to both sides of the top of the carbon mesh, and the side of the handle away from the carbon mesh extends to the outside of the shell.

[0016] 1. This utility model utilizes a heat insulation component to form a heat insulation cavity between the heat insulation cover and the shell. Together with the heating cover, delivery pipe, and exhaust pipe, it forms an air circulation channel. External air enters the heating cover through the inner cavity of the heat insulation cover, is heated, and then rises and is discharged, forming a continuous airflow heat insulation layer. This reduces the surface temperature of the shell and prevents the user from being burned by the shell. At the same time, the heated air is delivered to the charcoal mesh through the exhaust pipe to provide combustion-supporting flow, achieving double-layer heat insulation protection and improving the charcoal combustion efficiency. This solves the problem of single-layer structure causing rapid heat conduction and high surface temperature that easily leads to burns.

The fixing rod and the fixing mechanism are in cooperation with the elastic locking structure of the locking rod and spring. Pressing the pressure block can release the locking rod from the fixing rod, realizing the rapid opening and closing of the bottom plate. The ash after combustion is directly discharged through the unfolded bottom plate, avoiding the operation of disassembling components to clean ash in traditional ovens. The locking structure ensures that the bottom plate is stably closed during use, solving the safety hazards caused by the inconvenience of cleaning ash. Attached Figure Description

[0028] Specifically: the grilling mesh 2 facilitates the placement of food and allows for heating by charcoal; the charcoal mesh 3 facilitates the placement of charcoal; the heat insulation cover 41 isolates the surface of the shell 1, leaving a gap between the surface of the shell 1 and the heat insulation cover 41, and provides insulation through air; the heating cover 42 can be heated by charcoal, and the air inside the heating cover 42 is heated and rises to the exhaust pipe 44 and is discharged; at the same time, the air inside the heat insulation cover 41 is continuously transported to the heating cover 42, and the continuous flow of air inside the heat insulation cover 41 increases the heat insulation effect of the heat insulation cover 41; the exhaust pipe 44 can discharge the heated air to the shell 1, and by continuously supplying air to the shell 1, the charcoal inside can burn completely; the fixing mechanism 53 can cooperate with the fixing rod 52 to limit the bottom plate 51, allowing it to be closed and opened, facilitating the cleaning of the ash after combustion.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the fixing mechanism 53 includes a fixing shell 531. The left side of the fixing shell 531 is fixedly connected to the shell 1.

The heat shield 41 has a push plate, and a handle 6 is movably connected to the side of the heat shield 41 away from the housing 1. A heat shield 7 is fixedly connected to the inner wall of the heat shield 41. A handle 8 is fixedly connected to both sides of the top of the carbon mesh 3. The side of the handle 8 away from the carbon mesh 3 extends to the outside of the housing 1. A heat shield sheet is fixedly connected to the surface of the handle 8. A ventilation hole is opened on the surface of the exhaust pipe 44. An impeller 9 is movably connected to the bottom of the inner cavity of the heating cover 42. The top of the base plate 51 is movably connected to the heat shield 41 through a rotating shaft. A pressing slope is opened at the bottom of the clamping rod 534 to cooperate with the fixing rod 52. A support frame 10 is fixedly connected to both sides of the housing 1. The support frame 10 is U-shaped and has an anti-slip pad at the bottom.

[0031] Specifically: the pressure block 532 can compress the push block 533, causing it to control the lever 534 to compress the spring 535. The lever 534 can fix the fixing rod 52 to prevent the base plate 51 from rotating. The spring 535 can reset the push block 533 when the lever 534 is no longer compressed. The movable opening facilitates the movement of the lever 534. The push plate allows the user to easily push the pressure block 532, allowing the pressure block 532 to compress the push block 533.

The pressing slope allows the fixing rod 52 to be fixed by the clamping rod 534. The support frame 10 can stably support the housing 1. The anti-slip pad can increase the anti-slip effect of the support frame 10 and prevent it from shifting during use.

[0032] The working principle of this invention is as follows: First, charcoal is placed on top of the charcoal mesh 3 and ignited. The heat generated by combustion heats the food through the grill mesh 2. The heat insulation cavity between the heat insulation cover 41 and the shell 1 forms the first layer of heat insulation barrier, reducing heat conduction on the surface of the shell 1. External air enters the heat insulation cavity from the bottom of the heat insulation cover 41 and is then transported to the inner cavity of the heating cover 42 through the conveying pipe 43. The residual heat of the charcoal fire continuously heats the air inside the heating cover 42. The heated air is discharged upward through the exhaust pipe 44, forming an airflow circulation. This continuously replenishes the air inside the heat insulation cover 41 to the inside of the heating cover 42, ensuring continuous airflow inside the heat insulation cover 41. The flowing airflow forms an air insulation layer, further reducing the heat transfer temperature of the shell 1. The surface temperature of body 1 is heated, and the heated air enters the carbon mesh 3 area through the ventilation hole of exhaust pipe 44 to supplement oxygen for charcoal combustion and improve combustion efficiency. When it is necessary to clean the carbon ash, press the pressure block 532 of the fixing mechanism 53, push the push block 533 to squeeze the spring 535, so that the locking rod 534 is disengaged from the fixing rod 52. At this time, the bottom plate 51 rotates downward around the axis and unfolds. The carbon ash produced by the combustion of carbon mesh 3 is directly discharged through the unfolded bottom plate 51, avoiding the cumbersome operation of disassembling components required by traditional ovens. After cleaning, close the bottom plate 51 upward. The fixing rod 52 pushes the locking rod 534 to compress the spring 535 by squeezing the slope. After the locking rod 534 is reset, it locks with the fixing rod 52 to ensure that the bottom plate 51 is stably closed.
