Description

Technical Field

[0001] The present invention relates to the field of air fryers, in particular to a steam-type air fryer. Background Art

[0002] Air fryers are a popular kitchen appliance. However, most air fryers on the market offer only air frying, resulting in a monotonous cooking mode. This has led to the emergence of steam air fryers, which combine traditional air fryers with a steam supply system, offering both air frying and steam cooking, enriching their cooking capabilities. Existing steam air fryers use a vertical handle, which can easily cause the back of the hand to touch the outer wall of the drawer when gripping it, resulting in burns. Furthermore, the handle remains hot, making it uncomfortable to hold. Summary of the Invention

[0003] In response to the above problems, the present invention proposes a steam air fryer, which solves the defects of the existing steam air fryer using a vertical handle. When holding the handle, the back of the hand is likely to touch the outer wall of the movable drawer, causing burns, and the temperature of the handle is always high, which makes it uncomfortable to hold.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A steam-type air fryer comprises: a pot body, the pot body comprising an outer body, a frying basket respectively arranged in the outer body, and a steam assembly arranged on the outer body, the frying basket being equipped with a movable drawer, the movable drawer being equipped with a handle, a compression cylinder filled with inert gas being provided at the bottom of the frying basket, the compression cylinder being made of a heat-insulating material, a piston being provided in the compression cylinder, a cavity of the compression cylinder away from the handle being connected to a return pipe and an air outlet pipe inside and outside, a first magnet being installed on a side of the piston away from the handle, a second magnet being installed at the bottom of the movable drawer, and the opposing surfaces of the first magnet and the second magnet being attracted to each other; A heat exchange cavity is provided in the handle, and a pair of first semiconductor refrigeration plates are provided in the heat exchange cavity. A mobile power supply is provided at the bottom of the handle, and the mobile power supply is electrically connected to the first semiconductor refrigeration plate. One end of the air outlet pipe extends into the outside and is provided with a side passage pipe. The side passage pipe is inserted into the air outlet pipe and extends from the end of the air outlet pipe and is inserted into the heat exchange cavity; a heat exchange tube is provided inside the side of the movable drawer close to the handle, and the heat exchange tube is installed on the return pipe, and a second semiconductor refrigeration plate is provided on the outer side of the heat exchange tube; the cooling end of the first semiconductor refrigeration plate and the cooling end of the second semiconductor refrigeration plate are respectively facing the outer wall of the handle and the outer shell.

[0006] The present invention provides a first semiconductor refrigeration plate and a second semiconductor refrigeration plate, and supplies a mobile power source to the first semiconductor refrigeration plate and the second semiconductor refrigeration plate, so that the handle portion and the outer side surface portion of the heat exchange cylinder facing the handle maintain an appropriate temperature, thereby solving the problems that the back of the hand easily touches the outer wall of the movable drawer and causes burns, and the temperature of the handle is always high, which makes the hand uncomfortable to hold.

[0007] Optionally, a pair of heat-insulating flexible blocks covering the outside of the second magnet sheet are provided on the upper portion of the compression cylinder.

[0008] Optionally, a heat dissipation cylinder extending downwardly into the bottom of the pot body is provided on the inner side of the compression cylinder, and the heat dissipation cylinder is connected to the cavity on the same side of the compression cylinder as the first magnet sheet.

[0009] Optionally, an active cavity is provided on the upper portion of the handle, a pressing piece is installed in the active cavity, and a spring is provided between the pressing piece and the side wall of the active cavity.

[0010] Optionally, the return pipe is provided with an adjusting cylinder, and a movable ring made of magnetic material is provided on the outer side of the adjusting cylinder.

[0011] Optionally, a gear is mounted on the outer side of the movable ring, and a rack directly meshing with the gear is mounted on the pressing plate.

[0012] Optionally, a pair of first and second annular plates are provided in the return pipe, the first and second annular plates are arranged up and down, the first annular plate is made of magnetic material, and the second annular plate is fixedly connected to the return pipe.

[0013] Optionally, the first annular plate is provided with a first through hole, and the second annular plate is provided with a second through hole. The first annular plate and the opposite surfaces of the movable ring attract each other, and the first annular plate is driven to rotate under the movement of the movable ring, and overlap with the second annular plate, so that the first through hole and the second through hole overlap with each other.

[0014] Optionally, the first through hole is provided with a plurality of arc-shaped sheets made of memory metal, an elastic membrane is connected between two adjacent arc-shaped sheets, a circular membrane is adhered to the top of the arc-shaped sheet, and a plurality of diamond-shaped gaps are provided on the circular membrane. When the arc-shaped sheet reaches the transformation temperature, it stretches upward, pulling the circular membrane to expand, causing the gaps to open and increasing the gas flow rate.

[0015] In the present invention, as the temperature in the heat exchange chamber continues to rise, the arc-shaped sheet reaches the transformation temperature and stretches upward, pulling the circular membrane to expand, so that the gap is further opened, and the gas flow rate is increased, thereby achieving automatic expansion of the gas flow rate, and there is no need for the human body to sense the temperature rise and then adjust.

[0016] Beneficial effects

[0017] 1. The mobile power supply in the present invention supplies electricity to the first semiconductor refrigeration plate and the second semiconductor refrigeration plate for cooling, so that the handle part and the outer side surface part of the heat exchange cylinder facing the handle maintain an appropriate temperature, which solves the problem that the back of the hand is easy to touch the outer wall of the movable drawer and get burned, and the temperature of the handle is always high, which makes the hand uncomfortable to hold. At the same time, when the movable drawer is pushed into the outer shell, the first magnet sheet and the second magnet sheet are attracted to each other on their opposite surfaces, so that the second magnet sheet drives the first magnet sheet and the piston to move, compressing the gas in the compression cylinder, so that the cooling gas in the compression cylinder can enter the heat exchange cavity and the heat exchange cylinder to circulate and take away the temperature of the heating end of the first semiconductor refrigeration plate and the second semiconductor refrigeration plate, thereby improving the cooling effect.

[0018] 2. The operator in the present invention pushes the pressing plate to push the rack to drive the gear and the movable ring to rotate. Under the movement of the movable ring, the first annular plate is driven to rotate and overlap with the second annular plate, so that the first through hole and the second through hole overlap with each other, thereby allowing the air flow out of the compression cylinder to circulate, taking away the temperature of the heating end of the first semiconductor refrigeration plate and the second semiconductor refrigeration plate, thereby improving the cooling effect. By controlling the moving distance of the pressing plate, the overlapping area of the first through hole and the second through hole can be adjusted, thereby realizing manual adjustment of the cooling effect.

[0019] 3. In the present invention, as the temperature in the heat exchange chamber continues to rise, the arc-shaped sheet reaches the transformation temperature and stretches upward, pulling the circular membrane to expand, so that the gap is further opened, and the gas flow rate is increased, realizing automatic expansion of the gas flow rate, and there is no need for the human body to sense the temperature rise and then adjust.
