Abstract
Description
Technical Field
[0001] The utility model relates to the field of air fryers. Background Art
[0002] An air fryer is a kitchen cooking appliance that heats and fries food by heating air and then using a fan to generate hot air. In the prior art, an air fryer includes a main body and a fryer drawer mounted within the main body. A fan assembly is mounted above the fryer, comprising a hot air unit and a heat sink. The hot air unit is capable of fanning air within the fryer to generate a hot air flow for heating and frying the food, while the heat sink is capable of fanning air within the main body to generate a heat exchange with the outside of the main body through air inlets and outlets on the main body shell. When the air fryer is cooking frozen food or food with a high water content, the hot air flow heats the food, generating water vapor that flows within the fryer. Once the air fryer is finished cooking, the temperature within the fryer drops, and the water vapor condenses and accumulates at the bottom of the fryer. Excessive condensation can overflow from the fryer, requiring frequent cleaning, which can be very detrimental to the user experience. Summary of the Invention

[0005] The invention relates to an exhaust structure of an air fryer, comprising an exhaust device and an exhaust channel arranged between a body shell and an inner pot, wherein the exhaust device is arranged above the inner pot and has an air suction port and an air outlet, the upper portion of the body shell is provided with an exhaust port connected to the air outlet, the exhaust channel is arranged around the inner pot, the body shell is provided with an air inlet connected to the exhaust channel, the exhaust device is connected to the exhaust channel through the air suction port, and sucks the exhaust channel, and external air enters from the air inlet to form a suction airflow, an exhaust port is provided on the lower side wall of the inner pot, the exhaust port is connected to the exhaust channel and, driven by the suction airflow, sucks away the water vapor in the inner pot and discharges it from the body through the exhaust channel.
[0006] There are multiple steam exhaust ports, and each steam exhaust port is composed of multiple small holes.
[0007] The steam exhaust ports are respectively arranged at the lower two corners of the left and right side walls of the inner container.
[0008] The plurality of small holes constituting the steam exhaust port are arranged in an L-shaped distribution along the edge of the side wall of the inner container.
[0009] The air inlet is arranged at the lower part of the fuselage shell.
[0010] The air inlet on the fuselage shell and the steam exhaust port of the inner tank are arranged in the same horizontal direction.
[0011] The beneficial effects of the present invention are as follows: a steam exhaust port for exhausting water vapor is arranged on the side wall of the inner pot, and the steam exhaust port is arranged at the lower part of the side wall, which does not affect the heating and frying of food by the hot air device blowing out the hot air flow, and the steam exhaust port is connected to the original exhaust channel of the air fryer, and the suction air flow in the exhaust channel is used to suck the inner pot through the steam exhaust port, thereby taking away the water vapor existing in the inner pot, and after the air fryer completes cooking and frying, the exhaust device can continue to work for a period of time to take away the water vapor in the inner pot that is about to begin to condense due to the drop in temperature, and finally discharge it to the outside of the machine body through the exhaust channel and the exhaust device, thereby reducing the accumulation of water at the bottom of the inner pot due to the condensation of water vapor.

[0017] Reference Figures 1 to 4 An exhaust structure of an air fryer includes an exhaust device 3 and an exhaust channel 4 arranged between a body shell 1 and an inner pot 2. An exhaust port 21 is provided on the lower side wall of the inner pot 2, and the exhaust port 21 is connected to the exhaust channel 4.
[0018] The exhaust device 3 is arranged above the inner liner 2 and has an air intake 31 and an air outlet 32. The upper part of the fuselage shell 1 is provided with an exhaust port 12 connected to the air outlet 32. The exhaust channel 4 is arranged on the side of the inner liner 2. The fuselage shell 1 is provided with an air inlet 11 connected to the exhaust channel 4. The exhaust device 3 is connected to the exhaust channel 4 through the air intake 31 to suck the exhaust channel 4. The external air enters from the air inlet 11 to form a suction airflow that flows through the side of the inner liner 2 to take away heat and enter the exhaust device 3, and then blown out to the outside of the fuselage through the air outlet 32 and the exhaust port 12 to achieve heat dissipation inside the fuselage.
[0019] When the air fryer begins cooking, hot air from the hot air device begins to heat the food inside. During this heating process, moisture within the food evaporates, forming vapor that flows into the inner pot 2. Since the exhaust port 21 is located at the bottom of the inner pot 2, it does not affect the downward flow of the hot air. The exhaust port 21 connects to the exhaust duct 4. Driven by the suction airflow within the exhaust duct 4, the air in the inner pot 2 is drawn through the exhaust port 21, removing any moisture from the inner pot 2 and keeping it dry. After the air fryer finishes cooking, the exhaust device 3 continues to operate for a period of time to remove any moisture that is about to condense in the inner pot 2 due to the drop in temperature. The moisture is eventually discharged through the exhaust duct 4 and the exhaust device 3.
[0020] As a preferred embodiment of the present invention, the exhaust ports 21 are arranged in multiple locations and can be dispersed. Multiple suction ports are used to take away as much water vapor as possible from the inner tank 2, and each exhaust port 21 is composed of multiple small holes. On the one hand, it can further realize dispersed suction, and on the other hand, it avoids concentrated suction and affects the hot air flow. For this reason, the exhaust ports 21 are respectively arranged in the two lower corners of the left and right side walls of the inner tank 2, a total of four, and the multiple small holes that make up the exhaust ports 21 are arranged in an L-shaped distribution along the edge of the side wall of the inner tank 2, that is, they are arranged on the side and bottom edges of the side wall of the inner tank 2, so as to achieve the purpose of dispersed arrangement.
[0021] Preferably, the air inlet 11 is disposed at the lower portion of the outer shell 1 so as to be close to the steam exhaust port 21, and the suction force of the air inlet 11 is utilized to strengthen the suction force on the steam exhaust port 21. Furthermore, the air inlet 11 on the outer shell 1 and the steam exhaust port 21 of the inner liner 2 are arranged in the same horizontal direction, that is, the air inlet 11 and the steam exhaust port 21 are aligned, and the steam exhaust port 21 and the air inlet 11 are located at the beginning of the exhaust channel 4, thereby strengthening the suction force of the steam exhaust port 21 and improving the effect of extracting water vapor.
[0022] The utility model arranges a steam exhaust port 21 on the inner pot 2 and utilizes the original heat dissipation structure of the air fryer body to realize that the steam exhaust port 21 sucks the water vapor in the inner pot 2 and discharges the water vapor to the outside of the body, thereby reducing the accumulation of water at the bottom of the inner pot 2 due to condensation of water vapor.
