Description

Technical Field

[0001] The present invention relates to the technical field of air fryers, and in particular to a rotary pot body sealed cavity air fryer. Background Art

[0002] An air fryer is an intelligent household appliance that uses high-speed circulating hot air to fry food instead of the hot oil in a conventional frying pan. The body of an existing air fryer generally includes a sealed frying and roasting cavity, a pot body for holding food, a heating element and a blower that can send high-temperature and high-speed air into the pot body. It generates hot air through the heating element, and then uses the blower to blow the hot air into the pot to heat the food, making the hot air circulate in the pot body, frying the food using the oil in the food itself. The hot air comes into full contact with the food, and the surface of the food quickly dehydrates, achieving a crispy exterior and tender interior for the food, and achieving the frying effect.

[0003] Existing air fryers rely on the circulation of hot air to heat the food in the pot. The hot air goes from the mouth of the pot to the bottom of the pot, from the pot wall to the center of the pot, and the temperature gradually decreases from the corners of the pot to the center of the pot. At the same time, the food in the pot is in a relatively static state, resulting in uneven heat distribution inside. The food at the corners of the pot will receive more heat; the sealed frying and roasting cavity needs to be provided with holes to discharge the oil fume, but the opening of the holes destroys the airtightness and reduces the heat utilization efficiency. Making the holes smaller leads to the formation of high pressure inside the frying and roasting cavity. At the same time, the bottom of the pot body is completely sealed, and the negative pressure at the bottom blocks the downward circulation of air, preventing the hot air from coming into full contact with the food, and the oil and moisture on the surface of the food cannot be fully carried away, affecting the working efficiency of the air fryer and reducing the frying effect. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] The technical problem to be solved by the present invention is to provide a rotary pot body sealed cavity air fryer, which is provided with a rotatable pot body, making the food heated more evenly; its air duct structure can control the presence or absence of the exhaust state, enabling the air fryer to freely switch between the exhaust and internal circulation states, ensuring that the oil fume in the pot body can be fully discharged while guaranteeing the high working efficiency of the fryer; its cooling structure can cool the space inside the cavity outside the pot body, which is beneficial to the cooling of the housing.

[0006] (2) Technical Solutions

[0007] The solution adopted by the present invention to solve the above technical problems is a rotary pot body sealed cavity air fryer, which includes

[0008] a housing having a cavity with an open upper end;

[0009] a pot body rotatably disposed in the cavity, and the pot body is provided with a through hole communicating with the cavity;

[0010] A lid, rotatably connected to the housing, for opening or closing the top opening of the pot body;

[0011] A heating device, disposed inside the housing, and sending high-temperature air flow into the cooking cavity in the pot body through the through hole;

[0012] An air duct structure, for controlling the connection or blockage of the exhaust passage between the inside of the housing and the outside;

[0013] A cooling structure, for connecting the inside of the housing and the outside to form a cooling air flow circuit, and cooling the space of the cavity outside the pot body.

[0014] Specifically, the part of the pot body near the bottom is provided with the through holes in a ring shape, so that hot air is blown into the pot body from the through holes near the bottom of the pot body, and then the hot air heats the food in the pot body from bottom to top, making the food in the pot body heated evenly.

[0015] Adopting the above scheme, it is provided with a rotatable pot body, making the food heated more evenly; its air duct structure can control the presence or absence of the exhaust state, enabling the air fryer to freely switch between the exhaust and internal circulation states, ensuring that the oil fume in the pot body can be fully discharged while guaranteeing the high working efficiency of the fryer; its cooling structure can cool the space of the cavity outside the pot body, which is beneficial to the cooling of the housing.

[0016] Further, the cavity includes a first chamber and a second chamber arranged in parallel and communicating with each other, wherein the pot body is accommodated in the first chamber.

[0017] Further, the heating device includes a fan for driving the air flow, a heating element for heating the air flow, and a fan driving motor for providing power to the fan; wherein, the fan is disposed in the second chamber for driving the air flow to circulate between the first chamber and the second chamber; the heating element is disposed in the first chamber and / or the second chamber.

[0018] Specifically, a fan mounting member for mounting the fan is provided inside the housing, the upper part of the fan mounting member is open, and a matching part that penetrates up and down is mounted in a matching manner. After the matching part and the fan mounting member are connected, the second chamber is formed inside; an open end is provided at the lower end of the fan mounting member near one side of the first chamber, so that the second chamber is communicated with the first chamber.

[0019] Specifically, the heating element is arranged on the path of the airflow formed by the operation of the fan, can be surrounded by the outer wall of the pot body where the through hole is provided, close to the opening end connecting the first chamber and the second chamber or located above the opening end, can be arranged above the fan, can be arranged at the upper opening of the pot body, and can be selected according to needs.

[0020] Specifically, the heating element includes a heating tube, a light wave tube, a carbon tube, etc.

[0021] With the above solution, the heating element provides high temperature for the air, and the fan provides high speed for the air and enables the air to circulate, and the two cooperate to provide the pot body with stable high temperature and high-speed circulating airflow.

[0022] Furthermore, the air duct structure includes

[0023] A vent, provided on the shell, for connecting the inside of the shell with the outside;

[0024] The wind plate is rotatably connected to the opening of the second chamber, and has two states: one is a damper closed state, in which the wind plate is rotated to its free end to close the exhaust passage between the ventilator and the shell, and the upper opening of the first chamber is connected to the upper opening of the second chamber; the second is a damper open state, in which the wind plate is rotated to its free end to close the opening of the second chamber to cut off the passage between the upper opening of the first chamber and the upper opening of the second chamber, and the exhaust passage between the ventilator and the shell is connected.

[0025] Furthermore, the ventilator comprises

[0026] an air inlet portion, which is in communication with the second chamber;

[0027] an exhaust portion communicating with a space above the openings of the first chamber and the second chamber;

[0028] When the damper is in a closed state, the exhaust passage between the exhaust part and the shell is blocked, the exhaust part is in a closed state, and the air intake part is connected to the second chamber for air supply to the second chamber;

[0029] When the damper is in the open state, the exhaust part is connected to the exhaust channel in the shell, and the exhaust part is in the open state for discharging the airflow in the shell, and the air intake part is connected to the second chamber for intake of air into the second chamber.

[0030] Furthermore, an opening is formed at the space above the openings of the ventilation member close to the first chamber and the second chamber to form the exhaust portion, and an opening is formed above the second chamber to form the intake portion communicating with the second chamber; the exhaust portion and the intake portion are independent of each other, and the spatial position of the exhaust portion is relatively located above the intake portion.

[0031] Specifically, the ventilation member is disposed above the above-mentioned fitting member, and partially located above the fitting member and partially exceeding the fitting member.

[0032] Preferably, the ventilation member includes the intake portions arranged on both sides of the exhaust portion respectively, and the ventilation member includes an opening communicating with the intake portion, and the opening is arranged side by side with the ventilation portion; a through-hole member with a plurality of horizontal strip holes is connected to the outside of the ventilation member to increase the gas flow rate and improve the circulation speed between the inside and the outside.

[0033] Specifically, when the air damper is in the closed state, the exhaust portion is in the closed state, and the fan located in the second chamber operates, so that the internal hot air forms a thermal cycle between the air outlet side of the fan, the inside of the pot body, the top of the pot body, and the air inlet side of the fan. This cycle state enables the unused thermal energy to continuously circulate inside the cavity instead of being discharged outside the body and wasted. At the same time, the intake portion is connected to the second chamber, so the intake portion replenishes air for the second chamber, and the fan extracts external air through the intake portion to enter the cycle to achieve high pressure inside the cavity;

[0034] When the air damper is in the open state, the exhaust portion is in the open state, and the fan located in the second chamber operates. The hot air above the first chamber is directly discharged to the outside through the exhaust portion. At this time, the intake portion supplies air to the second chamber, and the fan extracts external air from the intake portion into the cavity, and then the hot steam is directly discharged to the outside through the exhaust portion;

[0035] The above two states can be freely switched, so that the oil fume generated in the pot body can be fully discharged while ensuring the high working efficiency of the air fryer.

[0036] Furthermore, the cooling structure includes

[0037] Cooling pipes, which are arranged on the same side of the second chamber in the housing and are isolated from the second chamber;

[0038] Wherein, an opening is provided on a side of the cooling pipe close to the second chamber for accommodating part of the fan; an arc-shaped channel is formed on a side of the lower end of the cooling pipe close to the first chamber and extends toward the shell, and the arc-shaped channel is closely attached to the shell, and the shell is provided with a first opening portion connected with the cooling pipe; an opening is provided on a side of the upper end of the cooling pipe close to the cover body and connected with the internal space of the cover body, and a second opening portion connected with the outer chamber space is provided on the cover body close to the outer chamber space between the first chamber and the pot body; the shell is provided with a third opening portion connected with the first chamber below the first chamber;

[0039] When the fan is running, the cold air flow from the outside is passed from the third opening portion to the outer chamber space, then from the second opening portion to the inside of the cover body, then from the opening portion to the cooling duct, and then from the first opening portion to the outside, thereby forming a cooling air flow loop.

[0040] Preferably, the cooling pipe is arranged above the fan mounting piece and is adjacent to the mating piece that forms the second chamber; then the portion of the opening end of the fan mounting piece close to one end of the second chamber located at the cooling pipe extends toward the first chamber and leads to the inner wall of the shell to form the arc channel.

[0041] Specifically, a fan is used to provide power, and a stable cooling structure is constructed among the outer chamber space between the first chamber and the outer wall of the boiler body, the space inside the cover body, the space inside the cooling pipe, and the outside world. When the fan is running, the air inside the cover body is sucked out to the outside world by the fan, resulting in low pressure inside the cover body. Since the second opening portion connects the inside of the cover body and the outer chamber space, the air in the outer chamber space flows upward into the cover body, and the outside air flows into the outer chamber space through the third opening portion, thereby forming a cooling airflow loop including the outside world, the outer chamber space, the cover body, the fan, and the outside world. The cold air takes away the heat radiated in the cavity through this cooling airflow loop, thereby achieving the purpose of cooling the shell.

[0042] Furthermore, the shell is located at the bottom of the cavity and is provided with a pot driving motor for driving the pot to rotate.

[0043] Specifically, outside the cavity sealed by the pot driving motor, the pot driving motor drives the pot located in the first cavity to rotate, so that the relatively static food in the pot body moves relative to the direction of hot air blowing, so that the heat distribution of the food in the fryer is more uniform.

[0044] Furthermore, the cover body includes a transparent portion located above the pot body for observing the food in the pot.

[0045] Specifically, through the transparent portion, the frying and roasting effects of food can be easily observed, and the food effects can be better controlled.

[0046] Furthermore, a food placement plate protruding from bottom to top is provided in the pot body, an oil receiving space is formed in the pot body below the food placement plate, and the food placement plate is provided with an oil leakage hole connected to the oil receiving space.

[0047] Specifically, the food placing plate is configured to be convex from bottom to top, so that the hot air entering through its through holes can fully contact the food on the food placing plate during the rising process, thereby heating the food more evenly, and the hot air can take away a large amount of moisture and a small amount of fat on the surface of the food. The fat that cannot be taken away will flow through the oil leakage holes on the food placing plate to the oil receiving space below it, which will not cause repeated frying of the food and affect the overall taste of the food.

[0048] (III) Beneficial effects

[0049] Compared with the prior art, the present invention designs an air fryer with a rotary pot body and a sealed cavity.

[0050] (1) The present invention is provided with a rotatable pot body, so that the relatively stationary food in the pot body can move relative to the direction of hot air blowing, so that the heat distribution of the food in the fryer is more uniform;

[0051] (2) The present invention is provided with an air duct structure, which can control the exhaust state, so that the air fryer can switch freely between the exhaust state and the internal circulation state, so that the oil smoke in the pot body can be fully discharged while ensuring the high working efficiency of the fryer;

[0052] (3) The present invention sets up a cooling structure, uses the fan to provide power, and constructs a stable cooling structure in the outer chamber space between the first chamber and the outer wall of the boiler body, the space in the cover body, the space in the cooling pipe, and the outside world; when the fan is running, the air in the cover body is sucked out to the outside world by the fan, resulting in low pressure in the cover body. Since the second opening part connects the inside of the cover body and the outer chamber space, the air in the outer chamber space flows upward into the cover body, and the outside air flows into the outer chamber space through the third opening part, thereby forming a cooling air flow loop of the outside world, the outer chamber space, the cover body, the fan, and the outside world. The cold air takes away the heat radiated in the cavity through this cooling air flow loop, thereby achieving the purpose of cooling the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] This embodiment:

[0067] Such as Figures 1 - 9As shown, a rotary pot body sealed cavity air fryer of the present embodiment comprises a shell 10 having a cavity with an upper opening; a pot body 11 rotatably disposed in the cavity, and the pot body 11 is provided with a through hole 111 communicating with the cavity; a cover body 12 rotatably connected to the shell 10, and used for opening or closing the top opening of the pot body 11; a heating device, disposed in the shell 10, and sending high-temperature airflow into the cooking cavity in the pot body 11 through the through hole 111; an air duct structure, used for controlling the connection or blocking of the exhaust channel between the inside of the shell 10 and the outside; a cooling structure, used for connecting the inside of the shell 10 and the outside to form a cooling airflow loop, and cooling the space of the cavity outside the pot body 11. Specifically, the portion of the pot body 11 near the bottom is provided with the through hole 111, so that hot air is blown into the pot body 11 from the through hole 111 near the bottom of the pot body 11, and the hot air heats the food in the pot body 11 from bottom to top, so that the food in the pot body 11 is heated evenly. Further, the shell 10 is provided with a pot body driving motor 19 at the bottom of the cavity for driving the pot body 11 to rotate. Specifically, outside the cavity sealed by the pot body driving motor 19, the pot body driving motor 19 drives the pot body 11 located in the first chamber 101 to rotate, so that the relatively stationary food in the pot body 11 generates relative movement with the hot air blowing direction, so that the heat distribution of the food in the fryer is more uniform. Further, the cover body 12 includes a transparent part 122 located above the pot body 11 for observing the food in the pot. Specifically, through the transparent part 122, the frying and roasting effect of the food can be conveniently observed, and the food effect can be better controlled. Furthermore, a food placement plate 112 is provided in the pot body 11, which is raised from bottom to top. An oil receiving space 113 is formed in the pot body 11 below the food placement plate 112. The food placement plate 112 is provided with an oil leakage hole 112-1 connected to the oil receiving space 113. Specifically, the food placement plate 112 is provided in a raised shape from bottom to top, so that the hot air entering through the through hole 111 can fully contact the food on the food placement plate 112 during the rising process, so that the food is heated more evenly, and the hot air can take away a large amount of moisture and a small amount of grease on the surface of the food. The grease that cannot be taken away will flow through the oil leakage hole 112-1 on the food placement plate 112 to the oil receiving space 113 below it, which will not cause it to fry the food repeatedly and affect the overall taste of the food. The above scheme is adopted, which is provided with a rotatable pot body 11, so that the food is heated more evenly; its air duct structure can control the exhaust state, so that the air fryer can freely switch between the exhaust state and the internal circulation state, so that the oil smoke in the pot body 11 can be fully discharged while ensuring the high working efficiency of the fryer; its cooling structure can cool the space outside the pot body 11 where the cavity is located, which is beneficial to the cooling of the shell 10.

[0068] Further, the cavity includes a first chamber 101 and a second chamber 102 which are arranged in parallel and communicate with each other. The pot body 11 is received in the first chamber 101.

[0069] Further, the heating device includes a blower 13 for driving the air flow, a heating element 14 for heating the air flow, and a blower drive motor for providing power to the blower 13. The blower 13 is disposed in the second chamber 102 for driving the air flow to circulate between the first chamber 101 and the second chamber 102. The heating element 14 is disposed in the first chamber 101 and / or the second chamber 102. Specifically, a blower mounting member 105 for mounting the blower 13 is provided in the housing 10. The upper part of the blower mounting member 105 is open, and a mating part 106 that penetrates up and down is fitted and mounted. After the mating part 106 and the blower mounting member 105 are connected, the second chamber 102 is formed inside. An open end 105-1 is provided at the lower end of the blower mounting member 105 near one side of the first chamber 101 so that the second chamber 102 communicates with the first chamber 101. In this embodiment, the heating element 14 is disposed on the path that the air flow formed by the operation of the blower 13 must pass through, and the heating element 14 is a heating tube, which is wound around the outer wall of the pot body 11 where the through hole 111 is provided near the open end 105-1 that communicates the first chamber 101 and the second chamber 102. With the above solution, the heating element provides high temperature for the air, and the blower 13 provides high speed for the air and enables the air to circulate. The two cooperate to provide a stable high temperature and high speed circulating air flow for the pot body 11.

[0070] Such as Figures 1 - 4As shown, further, the air duct structure includes a ventilation member 16 provided on the housing 10 for communicating the inside of the housing 10 with the outside; a wind plate 17 rotatably connected to the opening of the second chamber 102, which has two states. One is the air door closed state, where the wind plate 17 rotates to close the exhaust passage between the ventilation member 16 and the inside of the housing 10 with its free end, then the upper openings of the first chamber 101 and the second chamber 102 are communicated; the other is the air door open state, where the wind plate 17 rotates to close the opening of the second chamber 102 to cut off the passage between the upper openings of the first chamber 101 and the second chamber 102, then the exhaust passage between the ventilation member 16 and the inside of the housing 10 is communicated. Further, the ventilation member 16 includes an air intake portion 161 communicating with the second chamber 102; an exhaust portion 162 communicating with the space above the openings of the first chamber 101 and the second chamber 102; when in the air door closed state, the exhaust passage between the exhaust portion 162 and the inside of the housing 10 is cut off, so the exhaust portion 162 is in the closed state, and the air intake portion 161 communicates with the second chamber 102 for supplying air to the second chamber 102; when in the air door open state, the exhaust passage between the exhaust portion 162 and the inside of the housing 10 is communicated, so the exhaust portion 162 is in the open state for exhausting the air flow inside the housing 10, and the air intake portion 161 communicates with the second chamber 102 for supplying air to the second chamber 102. Further, the ventilation member 16 is provided with an opening near the space above the openings of the first chamber 101 and the second chamber 102 to form the exhaust portion 162, and an opening near the upper part of the second chamber 102 to form the air intake portion 161 communicating with the second chamber 102; and the exhaust portion 162 and the air intake portion 161 are independent of each other, and the spatial position of the exhaust portion 162 is relatively above the air intake portion 161. Specifically, the ventilation member 16 is provided above the above-mentioned fitting member, and part of it is above the fitting member and part of it extends beyond the fitting member. Preferably, the ventilation member 16 includes the air intake portions 161 arranged on both sides of the exhaust portion 162 respectively, and the ventilation member 16 includes an opening communicating with the air intake portion 161, and this opening is arranged side by side with the ventilation portion; a through-hole member 163 with a number of horizontal strip holes is connected to the outside of the ventilation member 16 to increase the gas flow rate and improve the circulation speed between it and the inside.Specifically, when the air damper is in the closed state, the exhaust part 162 is in the closed state, and the fan 13 located in the second chamber 102 operates, so that the internal hot air forms a thermal cycle between the air outlet side of the fan 13, the inside of the pot body 11, the top of the pot body 11, and the air inlet side of the fan 13. This cyclic state enables the unused thermal energy to continuously circulate inside the cavity instead of being discharged outside the body, resulting in waste. At the same time, the air inlet part 161 is connected to the second chamber 102, and the air inlet part 161 replenishes air to the second chamber 102. The fan 13 extracts external air through the air inlet part 161 to enter the cycle to achieve high pressure inside the cavity. When the air damper is in the open state, the exhaust part 162 is in the open state, and the fan 13 located in the second chamber 102 operates. The hot air above the first chamber 101 is directly discharged to the outside through the exhaust part 162. At this time, the air inlet part 161 supplies air to the second chamber 102, and the fan 13 extracts external air from the air inlet part 161 to enter the cavity. Subsequently, the hot steam is directly discharged to the outside through the exhaust part 162. The above two states can be freely switched, ensuring that the oil fume generated in the pot body 11 can be fully discharged while guaranteeing the high working efficiency of the air fryer.

[0071] Such as Figures 5 - 9As shown, further, the cooling structure includes a cooling pipe 18, which is arranged in the shell 10 on the same side of the second chamber 102 and isolated from the second chamber 102; wherein, the cooling pipe 18 is provided with an opening on a side close to the second chamber 102 for accommodating part of the fan 13; an arc-shaped channel 181 is formed on a side of the lower end of the cooling pipe 18 close to the first chamber 101 and extends toward the shell 10, and the arc-shaped channel 181 is close to the shell 10, and the shell 10 is provided with a first opening portion 103 connected to the cooling pipe 18; an opening portion 103 is provided on a side of the upper end of the cooling pipe 18 close to the cover 12 82 is connected with the internal space of the cover body 12, and the cover body 12 is provided with a second opening portion 121 connected with the outer chamber space near the first chamber 101 and the pot body 11; the shell 10 is located below the first chamber 101 and is provided with a third opening portion 104 connected with the first chamber 101; when the fan 13 is running, the external cold air flow is passed from the third opening portion 104 to the external chamber space, and then from the second opening portion 121 to the cover body 12, and then from the opening portion 182 to the cooling pipe 18, and then from the first opening portion 103 to the outside, thereby forming a cooling air flow loop. Preferably, the cooling pipe 18 is arranged above the fan 13 mounting member 105 and is adjacent to the above-mentioned matching member forming the second chamber 102; then the opening end 105-1 of the fan 13 mounting member 105 close to one end of the second chamber 102 located at the cooling pipe 18 extends toward the first chamber 101 and leads to the inner wall of the shell 10 to form the arc channel 181. Specifically, the fan 13 provides power, and a stable cooling structure is constructed among the outer chamber space between the first chamber 101 and the outer wall of the pot body 11, the space inside the cover body 12, the space inside the cooling pipe 18, and the outside world; when the fan 13 is running, the air inside the cover body 12 is sucked out to the outside world by the fan 13, resulting in low pressure inside the cover body 12. Since the second opening portion 121 connects the inside of the cover body 12 and the outer chamber space, the air in the outer chamber space flows upward into the cover body 12, and the outside air flows into the outer chamber space through the third opening portion 104, thereby forming a cooling airflow loop of the outside world, the outer chamber space, the cover body 12, the fan 13, and the outside world. The cold air takes away the heat radiated in the cavity through this cooling airflow loop, thereby achieving the purpose of cooling the shell 10.

[0072] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
