[0026] Please see Figure 1-6 This embodiment provides a technical solution: a steam air fryer with top and bottom heating, including a door assembly 7, a bottom shell 6 on the lower side of the door assembly 7, an electric ceramic heating plate 12 at the center of the bottom shell 6, a steam hole 16 at one corner of the bottom shell 6, an air fryer cavity 17 on the upper side of the bottom shell 6, a lower fan blade 13 on the upper side of the air fryer cavity 17, a heating tube 19 on the outer ring side of the lower fan blade 13, an upper fan blade 9 on the upper side of the lower fan blade 13, a motor 11 on the upper side of the upper fan blade 9, a steam generator 10 on one side of the motor 11, a water pump 14 connected to one side of the steam generator 10 via a pipe, a water tank 3 on the upper side of the water pump 14, a water outlet pipe 15 connected to the side of the water tank 3, and an exhaust pipe 8 on the other side of the motor 11.

[0027] An upper air hole 802 is provided on the side of the exhaust pipe 8 facing the upper fan blade 9, and a lower air hole 801 is provided on the lower side of the upper air hole 802. A water collection hopper 18 is connected to the lower side of one end of the exhaust pipe 8 through a slot.

[0028] The door assembly 7 includes an air fryer 701, a handle 702, a double-layered glass door 703, and a placement tray 704. The placement tray 704 is provided on the lower side of the air fryer 701, the handle 702 is fixedly connected to the outer side of the air fryer 701, and the double-layered glass door 703 is provided on the outer side of the air fryer 701.

[0029] The fryer cavity 17 is provided with an outer shell 1, and a knob 5 is provided on the upper side of the outer shell 1. A display screen 4 is provided on the outer shell 1 on one side of the knob 5.

[0030] A power cord 2 is connected to the bottom shell 6, and the water pump 14, water outlet pipe 15, steam generator 10 and steam hole 16 are connected by a pipe.

[0031] The coating of the air fryer 701 is mostly made of polytetrafluoroethylene, and the water tank 3 is detachable.

[0032] The working principle of the steam air fryer with top and bottom heating provided by this utility model is as follows: Figures 1-6 As shown, the outer shell 1 is made of high-temperature resistant and heat-insulating materials to ensure safety and energy efficiency during use. The door assembly 7 adopts a double-layer glass design, which not only facilitates the user's observation of the cooking process but also further enhances the heat insulation effect. The bottom of the steam air fryer 701 uses an electric ceramic stove heating plate 12 for heating. The electric ceramic stove heating plate 12 is usually composed of heating wires or heating plates. Current passes through the heating element to generate heat. This heating method has the advantages of fast heating speed, wide range of heat adjustment, and no electromagnetic radiation. In this oven, the electric ceramic stove heating plate 12 can provide stable and powerful heat to the bottom of the food, ensuring that the bottom of the food is fully heated to achieve ideal cooking results. It is especially suitable for foods that need to be browned and cooked through, such as pizza and bread.

[0033] This steam air fryer 701 is equipped with a heating element 19 on the top, which is generally made of stainless steel or quartz. The heating element 19 heats up quickly after being powered on, providing heat to the top of the food, so that the food is heated from top to bottom at the same time, making the food more evenly heated and avoiding the situation that the top is not fully cooked or unevenly colored. When baking meat, pastries and other foods, the upper heating element 19 can quickly form a golden and crispy outer skin on the surface of the food, lock in the internal moisture, and improve the taste and appearance of the food.

[0034] The steam generator is located on the top side inside this steam air fryer 701. It consists of a water tank 3, a steam generator 10, a water pump 14, and a steam delivery pipe. The water tank 3 is designed to be detachable for easy water addition and cleaning. The heating element rapidly heats the water in the water tank 3 to generate high-temperature steam. The steam is evenly distributed into the cooking chamber through the delivery pipe to provide a steam cooking environment for the food. The steam generator has an independent control switch and steam volume adjustment function, allowing users to flexibly adjust the steam volume according to different ingredients and cooking needs.

[0035] The air fryer 701 heats up by energizing the heating element 19 at the top of the pot. Utilizing the electrical and thermal conductivity of metal, the temperature is rapidly increased, heating the internal air in a short time. The motor 11 above the heating element 19 drives the upper fan blade 9 and lower fan blade 13 to rotate, causing the internal hot air to circulate rapidly, forming a convection heating method similar to solar hot air. An electric ceramic heating plate 12 is set at the bottom of the air fryer 701. When food is placed inside the air fryer 701, the hot air forms a vortex heat flow, contacting the food from all directions 360 degrees, quickly removing the moisture generated during heating, and forming a yellow and crispy surface layer on the food, achieving an appearance and taste effect similar to deep-frying or pan-frying. An air inlet and an air outlet are provided at the rear of the outer shell 1. Since cold air is denser than hot air, the air inlet is lower than the air outlet to facilitate air intake and exhaust.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
