Description

Technical Field

[0001] The utility model relates to an air fryer. Background Art

[0002] An air fryer is an appliance that uses hot air to cook foods, such as deep-fried foods. Air fryers pass hot air over food to increase heat transfer, thereby reducing cooking time. Their popularity stems from their ability to prepare food using significantly less oil than traditional deep-frying. However, known air fryers still produce fumes during use, particularly when cooking fatty foods at temperatures exceeding 140°C. Cooking fumes are a major drawback of air fryers, as they contain fine particles that pollute the air and create a persistent, unpleasant odor. Furthermore, cooking fumes from air fryers can trigger smoke detectors and air purifiers.

[0003] Chinese patent 201620167670.7 discloses an air fryer, comprising: a food preparation chamber; an air moving device for moving air in the food preparation chamber to generate an airflow; a heating device for heating the airflow generated by the air moving device so that the heated airflow can heat the food; and an air filter adapted to filter the air from the food preparation chamber.

[0004] The disadvantages of the above technical solution are that the air filter is huge and the exhaust line of the oil smoke is too tortuous, which is not conducive to the discharge of the oil smoke. Utility Model Content

[0005] In order to at least partially solve the deficiencies in the prior art, the main purpose of the present invention is to provide an air fryer with a simple structure and a direct exhaust line.

[0006] In order to achieve the above main purpose, the utility model discloses an air fryer, which includes a shell, a heating device, and a heat dissipation device.

Heat dissipation louvers are formed on both sides of the lower middle portion of the vertical tube, and the heat dissipation louvers are connected to the heat dissipation channel. In this way, the heat dissipation air in the heat dissipation cavity is discharged from the heat dissipation louvers through the heat dissipation channel.

[0010] According to a specific embodiment of the present invention, the inner horizontal tube and the inner vertical tube form a smoke channel through which smoke in the cooking cavity is discharged.

[0011] According to a specific embodiment of the present invention, the top portion of the vertical pipe is a wide opening; the top of the inner vertical pipe is a narrow opening; the bottom of the wide opening is flush with the top of the narrow opening, and the two are connected to form a stepped transition.

[0012] According to a specific embodiment of the present invention, a side air louver is provided on the side wall of the top of the vertical pipe.

[0013] According to one embodiment of the present invention, the air fryer is provided with a top air inlet and a bottom air inlet. Heat dissipation gas enters the heat dissipation cavity through the top air inlet and is discharged through the heat dissipation channel. Cooking gas enters the cooking cavity through the top and bottom air inlets and is discharged through the smoke channel.

[0014] According to a specific embodiment of the present invention, the bottom air inlet is located below the front panel of the housing, and the vertical pipe is provided on the rear panel of the housing. For example, the vertical pipe can be opposite to the inner container handle.

[0015] According to a specific embodiment of the present invention, the exhaust pipe further includes a removable top cover, which is arranged on the top of the vertical pipe. The removable top cover includes a top plate, left and right side plates, and an outer plate. The left and right side plates and the outer plate are connected to the lower surface of the top plate to form a semi-enclosed structure; smoke windows are opened on the top plate and the outer plate.

[0016] According to a specific embodiment of the present invention, the inner walls of the left and right side panels are provided with limit strips, and filter cotton is provided on the limit strips. The filter cotton can filter the oil smoke and ensure that the gas discharged from the exhaust pipe is pollution-free.

[0017] According to a specific embodiment of the present invention, the detachable top cover further includes a top cover handle, which is connected to the upper surface of the top plate and is arranged at one end of the top plate close to the shell.

[0018] According to a specific embodiment of the present invention, a limit block is provided on the outer wall of the vertical pipe to prevent the outer wall of the vertical pipe from directly contacting the wall.

[0019] The utility model has the following beneficial effects:

[0020] 1. The smoke from the cooking chamber and the heat dissipation gas from the heat dissipation chamber are discharged separately from the exhaust pipe to prevent the smoke and heat dissipation gas from mixing;

[0021] 2. By setting the exhaust pipe to exhaust upward, it avoids exhausting directly to the rear (wall);

[0022] 3. The exhaust pipe is equipped with a detachable top cover to facilitate the replacement of filter cotton.
