Description

Technical Field

[0001] This invention relates to the field of air fryer technology, and in particular to a novel type of air fryer. Background Technology

[0002] As living standards improve, people are paying more and more attention to healthy eating. In order to provide healthy fried foods, air fryers that do not require oil to fry food have appeared on the market. Existing air fryers use high-speed air circulation technology. By turning on the heating device to heat the internal air, the motor drives the fan to form a rapid circulation of hot air inside the working chamber used for cooking, using hot air to replace hot oil to achieve the frying effect of food.

[0003] However, the heating devices in existing air fryers are all powered by high-power electric heating. This type of heating device has certain drawbacks: the air fryer can only be used at home by plugging it in, and cannot be taken outdoors, which causes great inconvenience. Summary of the Invention

[0004] This invention provides a novel type of air fryer that optimizes the internal structure of traditional air fryers to solve the problem that existing air fryers cannot be used outdoors.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A novel air fryer is provided, comprising an outer shell, a fan assembly installed in the upper part of the outer shell, an outer pot in the lower part of the outer shell, a detachable heat source installed on the side and / or bottom of the outer pot, a cooking cavity inside the outer pot, and an inner pot for holding food within the cooking cavity; the internal structure of the air fryer is optimized, reducing the number of electrical components, and using a detachable heat source instead of a traditional high-power electric heating element to enable outdoor use of the air fryer.

[0006] As a supplement to the technical solution described in this invention, the outer shell includes an upper outer shell, which is spliced ​​and fixed to the outer pot. The outer pot and the outer shell are combined together, which reduces the material used in the outer pot and makes it convenient to detach the heat source of the outer pot.

[0007] As a supplement to the technical solution described in this invention, an air duct plate is installed inside the upper outer shell, and the fan assembly includes a motor and a hot air circulation fan. The motor is installed above the air duct plate, and the output shaft of the motor is connected to the hot air circulation fan located below the air duct plate. The air duct plate not only serves as a motor mounting bracket, but also separates the cooking cavity from the motor and other components, reducing the damage to the motor and other components caused by the airflow in the cooking cavity.

[0008] As a supplement to the technical solution described in this invention, the outer shell includes an upper outer shell and a lower outer shell, the upper outer shell and the lower outer shell are spliced ​​and fixed together, the outer pot is set inside the lower outer shell, and the detachable heat source is installed in the space between the lower outer shell and the outer pot; the outer shell is designed as an upper and lower split structure to facilitate internal maintenance of the air fryer.

[0009] As a supplement to the technical solution described in this invention, the lower end of the outer shell is open, the detachable heat source is located at the bottom of the outer shell, and the outer pot is placed on the detachable heat source; the outer shell and the detachable heat source are combined, and the detachable heat source acts as a stove-like platform, not only providing support for the outer shell and the outer pot, but also providing heat to the outer pot.

[0010] As a supplement to the technical solution described in this invention, an air duct plate is installed at the upper port of the outer pot. A heat dissipation cavity is formed between the outer surface of the air duct plate and the outer shell. A blower channel is formed between the outer surface of the outer pot and the outer shell. The blower channel is connected to the heat dissipation cavity and the detachable heat source. The fan assembly includes a motor, a heat circulation fan, and a heat dissipation blower fan. The motor is installed above the air duct plate. The heat circulation fan and the heat dissipation blower fan are both sleeved on the output shaft of the motor. The heat dissipation blower fan is located inside the heat dissipation cavity, and the heat circulation fan is located below the air duct plate. The air generated by the heat dissipation blower fan is introduced into the detachable heat source through the blower channel, which can provide airflow for combustion and / or local heat dissipation for the detachable heat source. The heat circulation fan is used for airflow circulation within the cooking cavity.

[0011] As a supplement to the technical solution described in this invention, the outdoor power supply for the air fryer is a portable power supply or a car battery, because portable power supplies or car batteries are common outdoor power sources, and only need to provide a small amount of power, which is very convenient.

[0012] As a supplement to the technical solution described in this invention, there is a gap between the outer pot and the inner pot, and the bottom of the inner pot is provided with an air vent. When the hot air circulation fan rotates, it drives the airflow in the cooking cavity to flow along the gap between the inner pot and the outer pot to the bottom of the inner pot, and then enters the inner pot from the air vent at the bottom of the inner pot, thereby realizing the airflow circulation in the cooking cavity.

[0013] As a supplement to the technical solution described in this invention, the detachable heat source is selected from one of the following: a combustible heating material, a chemical reaction heating material, or a low-voltage electrically driven heat source; the combustible heating material is selected from one of the following: charcoal, coal, coal briquettes, or alcohol. The above materials are merely examples and are not limited thereto.

[0014] Beneficial effects: This invention relates to a novel type of air fryer, which retains only a fan assembly with low power consumption inside the air fryer, eliminating the need for a high-power electric heating element. An external, detachable heat source is used instead of the heating element, enabling the air fryer to be used outdoors. The outdoor power supply for the air fryer can be a portable power source or a car battery, which only requires a small amount of power, making it very convenient. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] The embodiments of the present invention relate to a novel type of air fryer, such as... Figure 1-3 As shown, the air fryer only retains the fan assembly 6, which has a low power requirement, and eliminates the need for a high-power electric heating element. Instead, an external, detachable heat source 2 is used to replace the heating element, allowing the air fryer to be powered by a portable power source or a car battery when outdoors.

[0021] The air fryer includes an outer shell 1, a fan assembly 6 is installed in the upper part of the outer shell 1, and an outer pot 3 is provided in the lower part of the outer shell 1. A detachable heat source 2 is installed on the side and / or bottom of the outer pot 3. The interior of the outer pot 3 is a cooking cavity, and an inner pot 4 for holding food is provided in the cooking cavity.

[0022] Example 1:

[0023] like Figure 1As shown, the air fryer includes an outer shell 1, which is composed of an upper outer shell 11 and a lower outer shell 12. The upper outer shell 11 is equipped with a heat circulation fan 9 and a motor 8 that drives the heat circulation fan 9 to rotate. The lower outer shell 12 is equipped with an outer pot 3. A detachable heat source 2 is installed in the space between the lower outer shell 12 and the outer pot 3.

[0024] The outer pot 3 is made of a metal material with good thermal conductivity. The inner wall of the outer pot 3 forms a cooking cavity. The inner pot 4 is provided inside the outer pot 3 to hold the food. There is a gap between the outer pot 3 and the inner pot 4. An air vent 5 is opened at the bottom of the inner pot 4. When the heat circulation fan 9 rotates, the heat circulation fan 9 will drive the airflow in the cooking cavity to flow along the gap between the inner pot 4 and the outer pot 3 to the bottom of the inner pot 4. Then, it enters the inner pot 4 from the air vent 5 at the bottom of the inner pot 4. After the airflow heats the food, it flows from the top of the inner pot 4 to the heat circulation fan 9, thereby realizing the airflow circulation in the cooking cavity.

[0025] As a design option for the detachable heat source 2, the detachable heat source 2 can be set close to the side of the outer pot 3, or it can be set close to the bottom of the outer pot 3. Alternatively, the detachable heat source 2 can be set on both the side and the bottom of the outer pot 3, so that heat can be conducted to the outer pot 3, and then heated when the circulating airflow in the cooking cavity passes through it, so that the cavity obtains a high-temperature circulating airflow to heat the food in the inner pot 4.

[0026] As an example of the structural design of the outer shell 1, the upper outer shell 11 and the lower outer shell 12 are spliced ​​together. The two parts can be fixed by fasteners or by snap-fit, as long as the two parts can be detached.

[0027] Example 2:

[0028] like Figure 2 As shown, the air fryer includes an outer shell 1, which includes an upper outer shell 11. The upper outer shell 11 and the outer pot 3 are joined and fixed together. A heat circulation fan 9 and a motor 8 that drives the heat circulation fan 9 are installed inside the upper outer shell 11. A detachable heat source 2 is installed on the side and / or bottom of the outer pot 3.

[0029] The outer pot 3 is made of a metal material with good thermal conductivity. The inner wall of the outer pot 3 forms a cooking cavity. The inner pot 4 is provided inside the outer pot 3 to hold the food. There is a gap between the outer pot 3 and the inner pot 4. An air vent 5 is opened at the bottom of the inner pot 4. When the heat circulation fan 9 rotates, the heat circulation fan 9 will drive the airflow in the cooking cavity to flow along the gap between the inner pot 4 and the outer pot 3 to the bottom of the inner pot 4. Then, it enters the inner pot 4 from the air vent 5 at the bottom of the inner pot 4. After the airflow heats the food, it flows from the top of the inner pot 4 to the heat circulation fan 9, thereby realizing the airflow circulation in the cooking cavity.

[0030] As a preferred option for the detachable heat source 2, the detachable heat source 2 is placed directly at the bottom of the outer pot 3, and the outer pot 3 is placed directly on the detachable heat source 2, which makes it more convenient to use.

[0031] As a preferred installation method for the fan assembly 6, the fan assembly 6 is mounted on the air duct plate 7. The air duct plate 7 is installed inside the upper housing 11, and a motor 8 is mounted on the air duct plate 7. The output shaft of the motor 8 is connected to the heat circulation fan 9 located below the air duct plate 7.

[0032] As an explanation of the air duct plate 7, the outer shell 1 is divided into upper and lower chambers by the air duct plate 7. The upper chamber is used to house components such as the motor 8, and the lower chamber is used for cooking food. The air duct plate 7 not only serves as a motor mounting bracket, but also separates the internal space of the outer shell 1, reducing the damage to the motor 8 caused by airflow in the cooking chamber.

[0033] As an explanation of the structural scheme of the outer shell 1, the upper outer shell 11 and the outer pot 3 are spliced ​​together vertically. The two parts can be fixed by fasteners or by snap-fit, as long as the two parts can be disassembled.

[0034] Example 3:

[0035] like Figure 3 As shown, the air fryer includes an outer shell 1. A heat circulation fan 9 and a motor 8 that drives the heat circulation fan 9 are installed inside the upper part of the outer shell 1. The outer shell 1 is shaped like a cover and the lower end of the outer shell 1 is open. The detachable heat source 2 is installed at the bottom of the outer shell 1. The outer pot 3 is placed on the detachable heat source 2. The outer pot 3 is made of a metal material with good thermal conductivity. The inner wall of the outer pot 3 forms a cooking cavity. The inner pot 4 for holding food is provided inside the outer pot 3.

[0036] There is a gap between the outer pot 3 and the inner pot 4. The bottom of the inner pot 4 has an air vent 5. When the hot air circulation fan 9 rotates, the hot air circulation fan 9 will drive the airflow in the cooking cavity to flow along the gap between the inner pot 4 and the outer pot 3 to the bottom of the inner pot 4. Then, it enters the inner pot 4 from the air vent 5 at the bottom of the inner pot 4. After the airflow heats the food, it flows from the top of the inner pot 4 to the hot air circulation fan 9, thereby realizing the airflow circulation in the cooking cavity.

[0037] As a preferred installation method for the fan assembly 6, the fan assembly 6 is mounted on the air duct plate 7. The air duct plate 7 is mounted on the upper end of the outer pot 3, and a motor 8 is mounted on the air duct plate 7. At least one heat circulation fan 9 is mounted on the output shaft of the motor 8.

[0038] As an explanation of the air duct plate 7, the upper port of the outer pot 3 is equipped with the air duct plate 7. The air duct plate 7 can not only serve as a motor mounting bracket, but also seal the upper port of the outer pot 3 to reduce the damage of the airflow in the cooking cavity to the motor 8.

[0039] As a preferred embodiment of the air duct plate 7, an air duct plate 7 is installed at the upper end of the outer pot 3. A heat dissipation cavity is formed between the outer surface of the air duct plate 7 and the outer shell 1. A blower channel 10 is formed between the outer surface of the outer pot 3 and the outer shell 1. The blower channel 10 is connected to both the heat dissipation cavity and the detachable heat source 2. The fan assembly 6 includes a motor 8, a heat circulation fan 9, and a heat dissipation blower fan 13. The motor 8 is installed above the air duct plate 7. The heat circulation fan 9 and the heat dissipation blower fan 13 are both mounted on the output shaft of the motor 8. The heat dissipation blower fan 13 is located inside the heat dissipation cavity, and the heat circulation fan 9 is located below the air duct plate 7. The air generated by the upper heat dissipation blower fan 13 is introduced into the detachable heat source 2 through the blower channel 10, which can provide airflow for combustion and / or localized heat dissipation to the detachable heat source 2, thereby achieving a better heating effect. The lower heat circulation fan 9 is used for airflow circulation within the cooking cavity. By synchronously driving two fans with one motor 8, the number of driving components is reduced, and the internal space arrangement is optimized.

[0040] As an explanation of the structural scheme of the outer casing 1, the outer casing 1 and the detachable heat source 2 can be fixed by fasteners or by clips, as long as the two parts can be detached.

[0041] The detachable heat source 2 in Examples 1 to 3 can be selected from combustible heating materials, chemical reaction heating materials, or low-voltage electric driven heat sources. The combustible heating materials can be charcoal, coal, coal briquettes, alcohol, etc. The chemical reaction heating materials are like self-heating hot pots, which use chemical reaction to release heat as a heat source. The low-voltage electric driven heat source uses other non-high-voltage electric driven heat sources to meet the requirements for outdoor use.

[0042] The self-heating hot pot's heating principle comes from a heating pack inside the packaging box. This heating pack has a wide range of uses. Its main components are sodium carbonate, calcined diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, and quicklime. When filled with cold water, it can heat the water to over 150°C, and the steam temperature can reach 200°C, which can be used to cook food.

[0043] The detachable heat source 2 in Example 1 is equivalent to an internal heat source, which is usually a chemical reaction heat source or a low-voltage electric driven heat source.

[0044] In Examples 2 and 3, the detachable heat source 2 is equivalent to an external heat source, similar to a stove, which not only supports the outer pot 3 but also provides heat to it. Commonly used heat sources include combustible heating elements, chemical reaction heating elements, or low-voltage electrically driven heat sources.
