In this embodiment, the cooking appliance includes a base, a cooking assembly and a steam generator 13 disposed on the base, and a hot air cavity matched with the cooking assembly, the cooking assembly is provided with a cooking cavity 11, the hot air cavity is provided with a hot air assembly, and heat generated by energizing the hot air assembly is input into the cooking cavity 11, so that food materials in the cooking cavity 11 are heated and cooked.

In this embodiment, the hot air assembly includes a fan and a heating tube, the heating tube is located at the periphery of the fan, the fan extracts air in the cooking cavity 11 and forms an air flow flowing through the heating tube, the air flow absorbs heat through the heating tube and forms hot air flowing back to the cooking cavity 11, and the hot air contacts with food materials and realizes heat transfer after flowing into the cooking cavity 11, so that the food materials are gradually cooked from outside to inside. The temperature of the hot air is reduced due to contact with the food materials and the hot air is diffused into the cooking cavity 11, so that an air source is provided for the hot air component to extract and heat again, and the air is circularly extracted and heated to improve the heat utilization efficiency. Steam generated by the steam generator at the bottom enters the cooking cavity, so that the food material is steamed or steamed and roasted.

When the cooking device is used, firstly, food is put into the cooking cavity 11, then, the cooking cavity 11 is plugged, the cooking cavity 11 is isolated from an external space and communicated with the hot air cavity, finally, hot air is generated through the hot air component, the hot air is input into the cooking cavity 11, so that the food is heated and cooked, and steam is generated by the steam generator when steam is needed in the preparation process of the food, and enters the cooking cavity.

In this embodiment, the housing 1 is provided with a vent assembly 2, and the vent assembly 2 spans between the cooking cavity 11 and the external space. When in use, the liquid in the cooking cavity 11 and the moisture in the food material can be evaporated due to heating, so that the air in the cooking cavity 11 can be discharged outside through the exhaust assembly 2 due to the rising of the air pressure, and the cooking safety is ensured. Because the windage of exhaust assembly 2 is less, lead to in the cooking cavity 11 atmospheric pressure and external atmospheric pressure approach all the time, the interior food material of cooking cavity 11 can influence the culinary art efficiency because of the atmospheric pressure is lower in the cooking cavity 11, influences the use experience. For this reason, set up buffer chamber 21 in exhaust subassembly 2, the air current of cooking cavity 11 inside and outside is arranged after the needs to flow through buffer chamber 21 for cooking cavity 11 only can order about the air current to flow through buffer chamber 21 after accumulating higher atmospheric pressure and arrange outward, and then make cooking cavity 11 can maintain in the micropressure state that is higher than external atmospheric pressure for a long time, both effectively promote cooking efficiency, promote and use experience, can also ensure that the internal atmospheric pressure of cooking cavity 11 maintains in predetermineeing the scope, ensure safe in utilization.

When the cooking cavity 11 is in a micro-pressure state, the air pressure in the cooking cavity 11 is slightly higher than the preset range of the external air pressure, so that the ambient pressure can be increased through the food materials, the cooking efficiency is further improved, and potential safety hazards caused by overhigh air pressure in the cooking cavity 11 can be prevented.

Under normal conditions, the cooking effect of the air fryer can be ensured by arranging the buffer cavity, but in the process that the hot air component acts on the food, the steam supplementing process is increased in the process of hot air baking for better cooking the food, so that the taste of the food is improved, the dry firewood of the taste caused by the moisture of the food in the process of taking away the food by hot air is avoided, and in addition, the steam supplementing process is used for realizing the steaming and baking effect of the food in the cooking cavity, thereby being beneficial to improving the cooking efficiency and producing different cooking effects. Because the steam temperature that produces is the boiling point temperature of water, generally is about one hundred degrees, and the baking temperature of hot-blast subassembly needs higher temperature, so, after steam generator produced steam enters into the culinary art chamber, can then lead to the temperature reduction in the culinary art chamber for the original micropressure state in the culinary art chamber changes, has influenced the culinary art effect.

In this embodiment, the buffer chamber can adjust the air pressure in the cooking chamber, and when steam enters the cooking chamber, the speed of air discharge is reduced, so that the air pressure in the cooking chamber is increased to ensure that the cooking chamber is in a micro-pressure steam state. The buffer cavity belongs to a communicating device, and the internal air pressure is correspondingly regulated by regulating the communication area between the buffer cavity and the outside.

Embodiment two:

When the cooking cavity is used, air flowing out of the cooking cavity 11 needs to sequentially pass through the lower through hole 221, the buffer cavity 21 and the upper through hole 231 and then flow into an external space, the upper through hole 231 and the lower through hole 221 are respectively arranged on the top wall and the bottom wall of the buffer cavity 21, the flow path length of air flow in the buffer cavity 21 is effectively increased, and then the air pressure in the cooking cavity 11 is increased by improving the wind resistance when the air flow flows through the buffer cavity 21, so that the food material is ensured to be quickly cooked.

In this embodiment, the exhaust assembly 2 includes an exhaust pipe 24 vertically disposed, a lower plate 22 with a lower through hole 221 is disposed in the middle of the exhaust pipe 24, an upper plate 23 with an upper through hole 231 is disposed on the top, and the exhaust pipe 24 is located between the upper plate 23 and the lower plate 22 to form the buffer chamber 21. The exhaust pipe 24 is inserted on the shell 1 in an axial vertical posture, which is convenient for production and assembly and ensures that the air path is smooth. An upper plate 23 and a lower plate 22 are arranged in the exhaust pipe 24, and a buffer cavity 21 is formed by enclosing the upper plate 23, the lower plate 22 and the inner side wall of the exhaust pipe 24.

In this embodiment, the upper through holes 231 are plural and are disposed on the top wall of the buffer chamber 21, and the axis of the upper through holes 231 is inclined from bottom to top to rear to form an exhaust area at the rear of the housing 1. The provision of the plurality of upper through holes 231 improves the efficiency of exhausting the air flow from the buffer chamber 21, thereby providing a space for receiving the air flow from the cooking chamber 11 later. The lower port axis of the upper through hole 231 is vertically arranged, and the axial direction of the upper port is inclined from bottom to top to the rear for guiding the high-temperature air to flow to the exhaust area behind the shell 1 for conveying, so that the situation that a user scalds due to contact with the high-temperature air is effectively prevented, and the use safety is ensured.

In this embodiment, as shown in fig. 3, a plugging valve plate 25 capable of being adjusted in a lifting manner is disposed below the lower plate 22, and the plugging valve plate 25 can be switched in a lifting manner between a plugging state in which the lower through hole 221 is plugged and an idle state in which the plugging valve plate is separated from the lower plate 22. The plugging valve plate 25 is liftably disposed below the lower plate 22, so that the plugging valve plate 25 can be liftably switched between a plugging state of capping the plugging lower through hole 221 and an idle state of being separated from the lower plate 22. Meanwhile, an inverted cone-shaped plugging bulge 26 is arranged on the plugging valve plate 25, the plugging bulge 26 is inserted into the lower through hole 221, and the passable area of the lower through hole is adjusted in the process of lifting the valve plate. Thereby achieving the effect of adjusting the internal pressure of the cooking cavity.

In the use process, when the plugging valve plate 25 is in an idle state, the plugging valve plate 25 is positioned below the lower plate 22 and is not contacted with each other, the plugging valve plate 25 is provided with a gas transmission hole which is vertically projected and staggered with the lower through hole, after the gas pressure in the cooking cavity 11 rises, the gas flow passes through the valve plate 25 through the gas transmission hole and enters the buffer cavity 21 after passing through the lower through hole 221, so that the gas pressure in the cooking cavity 11 is effectively reduced; when steam is required to enter the cooking cavity for action and food materials, the plugging valve plate 25 is controlled to ascend and gradually switch to a plugging state, plugging bulges on the plugging valve plate enter and plug the lower through holes 221, and the air pressure in the cooking cavity 11 can be increased due to the fact that air flow cannot be discharged through the exhaust assembly 2. The specific degree of occlusion can be adjusted according to the specific function and the time period during which the steam is introduced.

The embodiment provides a scheme of adjusting up and down, and of course, the plugging valve plate can also be moved left and right transversely to adjust the accessible area of the lower through hole, so that when steam enters, the area of the through hole is reduced, the air pressure in the cooking cavity is improved, and the cooking effect is ensured. Of course, the upper through hole may be adjusted. And are not illustrated herein.

Specifically, an electromagnetic switch can be arranged on the lower plate, the plugging valve plate is magnetically attracted to the plate, and magnetic force generated by the electromagnetic switch drives the plugging valve plate to rise and switch to a plugging state. The electromagnetic switch is electrified to generate magnetic force and upwards attract the plugging valve plate below, so that the plugging valve plate is switched from an idle state to a plugging state; when the electromagnetic switch is powered off, the magnetic force disappears, and the plugging valve plate falls from the plugging state to the idle state under the action of self gravity. The lifting of the plugging valve plate is controlled by the on-off operation of the electromagnetic switch, so that the air pressure in the cooking cavity is ensured to be maintained in a preset micro-pressure state. The lifting of the plugging valve plate is controllable, so that the specific air pressure range in the micro-pressure state is variable, and the requirements of cooking different food materials are met.

Of course, the plugging valve plate can be manually adjusted, and when the adjustment is needed, a user is reminded of selecting whether to cook food materials with micro-pressure steam. At the moment, only a certain deflector rod is required to be arranged, so that a user can operate the deflector rod.

As shown in fig. 4, a liftable buffer ball 28 is disposed in the buffer chamber 21, and when the air pressure in the cooking chamber 11 is higher than the air pressure in the buffer chamber 21, the buffer ball 28 can be switched from the blocking state of the blocking lower through hole 221 to the suspending state of the blocking lower through hole 221 when the air flow blows. The buffer ball 28 closes the lower through hole 221 by using its own weight, so that the cooking cavity 11 needs to blow the buffer ball 28 upward away from the lower through hole 221 by lifting the air pressure therein, thereby maintaining the air pressure in the cooking cavity 11 in a micro-pressure state.

Specifically, the buffer ball 28 closes the lower through hole 221 by its own weight, so that the air pressure in the cooking chamber 11 is maintained in a minute pressure state. When the air pressure in the cooking cavity 11 rises, the air flow can be discharged outwards after driving the buffer balls 28 to separate from the lower through holes 221 upwards, the buffer balls 28 can fall and block the lower through holes 221 again after the air flow in the cooking cavity 11 is discharged outwards and the air pressure is reduced, and the cooking cavity 11 is ensured to be stably maintained in a micro-pressure state.

In this embodiment, the periphery of the upper port of the lower through hole 221 is provided with a guide ring 222, so that the bottom of the buffer ball 28 slides along the guide ring 222 and blocks the lower through hole 221, the diameter of the lower through hole 221 is smaller than that of the buffer ball 28, which can not only guide the buffer ball 28 and ensure that the center of the buffer ball 28 coincides with the axis of the lower through hole 221, but also ensure that the buffer ball 28 is supported by the periphery of the upper port of the lower through hole in a collision manner, and can improve the sealing reliability by increasing the contact area between the periphery of the upper port of the lower through hole and the surface of the buffer ball 28.

In this embodiment, the lower plate 22 is movable up and down to adjust the rising amplitude of the buffer ball, so that even if the buffer ball rises, the rising amplitude is small due to the effect of the rising space, so that it still partially seals the lower through hole, thereby adjusting the air pressure in the cooking cavity.
