Description

Technical Field

[0001] The utility model relates to an air fryer, in particular to an air fryer with a heating tube and a fan blade that are detachable for cleaning. Background Art

[0002] As a popular small household appliance in modern kitchens, the air fryer has been widely used due to its less oil and healthy cooking method. The existing air fryers mainly achieve the baking effect of food by setting a heating tube in the heating cavity and making the heated air flow through the air circulation system. This type of air fryer is usually designed as a fixed structure, in which the heating tube and the fan blade, as the core heating and air circulation components, are directly installed inside the body and cannot be easily disassembled and cleaned. Therefore, during the use of the air fryer, with the flow of air, oils, moisture, etc. in the food will fully contact the heating tube and the fan blade, resulting in easy contamination.

[0003] However, there are some inconveniences in the daily use of the existing air fryers, especially obvious defects are exposed in terms of cleaning and maintenance:

[0004] 1. In the structural design of the existing air fryers, the heating tube is usually fixedly installed inside the heating cavity or the body. Due to the complexity of its connection to the power supply and structure, the heating tube cannot be designed to be detachable. This leads to the accumulation of oils and food residues on the surface of the heating tube during long-term use, affecting the heating efficiency and even posing potential safety hazards. Since the heating tube cannot be disassembled, users cannot conduct in-depth cleaning and maintenance on it. Long-term dirt accumulation may cause the performance of the air fryer to decline, and there are also significant deficiencies in terms of cleaning and hygiene;

[0005] 2. In the existing air fryers, the fan blade is usually fixed on the motor spindle by a hex nut. To ensure the stability of the fan blade during high-speed rotation, the hex nut is designed to be relatively tight and requires special tools such as a wrench for disassembly. However, ordinary families usually only have common tools such as a screwdriver, lacking a professional wrench. Therefore, when users try to disassemble the fan blade for cleaning, it is often difficult to find a suitable tool, resulting in the inability to smoothly carry out the fan blade cleaning work. Therefore, it is necessary to make further improvements to it. Content of the Utility Model

[0026] The following further specifically describes this utility model with reference to the drawings. An air fryer with a detachable heating tube and fan blade for cleaning includes a main body 1. A heating cavity 2 is provided at the bottom of the main body 1. The heating cavity 2 is covered with an isolation net 3. A motor 4 is installed in the main body 1. The motor 4 is connected to a fan blade 5 located on the back of the isolation net 3 and drives it to rotate. A heating tube 6 is provided between the fan blade 5 and the isolation net 3;

[0027] The heating tube 6 is arranged in a spiral coil shape, and both ends of the heating tube 6 are connected into one body through a connecting piece 7. A jack 8 is arranged in the main body 1, and the heating tube 6 is fixed in the jack 8 through an inserting tube 9 fixed to the bottom of the connecting piece 7;

[0028] An elastic electrode piece 10 extends into the jack 8 in the jack 8. An electrode rod 11 extends outward from the end of the inserting tube 9. After the inserting tube 9 is inserted into the jack 8, the electrode rod 11 laterally presses the elastic electrode piece 10 to form an electrical connection therewith;

[0029] The motor 4 extends downward with a main shaft 12. A flat platform is arranged on the cylindrical surface of the main shaft 12, and the central hole of the fan blade 5 is sleeved on the flat platform and connected coaxially therewith;

[0030] A sleeve 13 is arranged on the back of the isolation net 3. The sleeve 13 is sleeved outside the main shaft 12, and its upper end surface presses against the outside of the central hole of the fan blade 5 to limit the axial displacement of the fan blade 5.

[0031] In one embodiment: the main shaft 12 is a stepped shaft, the flat platform is arranged on the stepped shaft, and the fan blade 5 is sleeved on the stepped shaft to limit the upward movement stroke of the fan blade 5.

[0032] In one embodiment: a plain bearing 14 is arranged at the top of the sleeve 13, and the plain bearing 14 contacts the fan blade to limit its downward movement stroke.

[0033] In one embodiment: a first fixing hole 15 is arranged on the connecting piece 7, and a first fixing screw passes through the first fixing hole 15 and is connected to the main body 1.

[0034] In one embodiment: a second fixing hole 16 is arranged on the isolation net 3, and a second fixing screw passes through the second fixing hole 16 and is connected to the main body 1.

[0035] In one embodiment: a silica gel insulating sleeve 17 is sleeved in the jack 8.

[0036] Working principle: In this case, the heating cavity 2 of the air fryer is located at the bottom of the main body 1 and is internally provided with a heating tube 6 in a spiral coil shape. The heating tube is powered by electricity for heating. The spiral coil design of the heating tube not only increases the contact area with air, improves the heat transfer efficiency, but also ensures a uniform heating effect inside the air fryer.

[0037] As the heating tube heats up, the hot air generated is circulated through the fan blade 5 located on the back of the isolation net 3. The motor 4 drives the fan blade to rotate, evenly blowing the hot air onto the surface of the food material to ensure that the food material is evenly heated throughout the cavity and achieve an efficient baking effect.

[0038] It should be noted that in this case, the main shaft 12 of the motor is coaxially connected to the central hole of the fan blade through a flat platform provided on its cylindrical surface. This design ensures the rotational stability of the fan blade. After the fan blade is coaxially connected to the main shaft, the sleeve 13 on the back of the isolation net is sleeved outside the main shaft and presses against the outer edge of the central hole of the fan blade, thus effectively restricting the axial displacement of the fan blade.

[0039] The advantage of this design is that the fan blade does not need to be fixed by nuts, eliminating the complexity of using hex nuts to fix the fan blade in traditional air fryers. When cleaning, users only need to simply use a screwdriver to remove the screws fixing the isolation net, and then they can easily disassemble the fan blade without using additional tools such as wrenches.

[0040] At the same time, both ends of the heating tube 6 are fixed by connecting pieces 7, and are electrically connected by inserting the insertion tube 9 into the jack 8 in the main body. There is an elastic electrode piece 10 in the jack. After the electrode rod 11 extending from the insertion tube of the heating tube is inserted into the jack, it laterally squeezes the elastic electrode piece to form a reliable electrical connection. Due to the design of the electrode rod, users can insert and remove the heating tube without additional tools. This design not only facilitates the maintenance and cleaning of the equipment, but also ensures the stability and safety of the electrical connection.

[0041] In this case, the fan blade realizes coaxial fixation and axial displacement restriction through the cooperation of the flat platform on the main shaft and the sleeve, completely eliminating the design of fixing the traditional fan blade with nuts. When disassembling, users do not need to use tools such as wrenches, and only need to use a screwdriver to remove the fan blade for cleaning. This design greatly facilitates the maintenance and cleaning operations of users.

[0042] In addition, the spiral winding design of the heating tube not only improves the thermal efficiency, but also ensures the uniform distribution of hot air. Combined with the rotation of the fan blade, the hot air can circulate efficiently, ensuring that the food in the air fryer is evenly heated. This design significantly improves the cooking efficiency of the air fryer and shortens the heating time. At the same time, the heating tube of the present utility model is connected to the circuit by a plug-and-play method, and users can easily disassemble the heating tube from the main body for cleaning or replacement. This design makes the daily cleaning and maintenance of the equipment more convenient while ensuring the safety of the electrical connection.

[0043] In summary, the present utility model not only simplifies the operation in the disassembly and assembly of the fan blade and the heating tube, but also avoids the hygiene problems caused by the long-term accumulation of grease and food residues through the above design. Users can easily clean these key components to ensure that the equipment remains efficient and clean for a long time, thereby extending the service life of the air fryer, so it can be widely promoted and used.

[0044] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
