The oxygen supply device 4 may supply the oxygen-rich gas to the cooking chamber 21 as pure oxygen or as a mixed gas containing oxygen, for example, as air.

In one embodiment of the present invention, the oxygen supply apparatus 4 comprises an air pump 41, an air inlet of the air pump 41 is connected to an air source, the air source provides an oxygen-enriched air, an air outlet 411 of the air pump 41 is connected to the cooking chamber 21, and the air pump 41 is connected to the controller 5 so that the air pump 41 is turned on under the control of the controller 5. An air pump 41 is fed from the air inlet and discharged from the air outlet 411, and the air pump 41 is operated under the control of the controller 5 to draw oxygen-enriched air from the air source into the cooking chamber 21, thereby achieving the purpose of supplying oxygen required for cooking toward the inside of the cooking chamber 21. The oxygen supply device 4 has a simple structure.

In one embodiment of the present invention, the air source may be air in the external environment of the cooking appliance 100, and the air inlet of the air pump 41 may be disposed outside the cooking appliance 100 to directly communicate with the external environment, so as to suck and deliver the air in the external environment into the cooking cavity 21 to provide the oxygen-rich air for the cooking process.

In one embodiment of the present invention, referring to fig. 1 to 10, the oxygen supply apparatus 4 further includes a gas delivery member 42, and the air pump 41 delivers gas into the cooking cavity 21 through the gas delivery member 42, thereby making the position of the air pump 41 more flexible and facilitating the communication between the air pump 41 and the cooking cavity 21.

In one embodiment of the present invention, referring to fig. 1 to 4, the air delivery member 42 includes a delivery pipe 421, one end (upper end as viewed in fig. 1 to 4) of the delivery pipe 421 is connected to the air outlet 411 of the air pump 41, and the other end (lower end as viewed in fig. 1 to 4) of the delivery pipe 421 is located in the cooking chamber 21. Specifically, the air pump 41 sucks the oxygen-enriched gas into the air pump 41 through the air inlet and then inputs the oxygen-enriched gas into one end (an upper end as shown in fig. 1 to 4) of the gas delivery member 42 through the air outlet 411 of the air pump 41, and since the other end (a lower end as shown in fig. 1 to 4) of the gas delivery member 42 is disposed in the cooking chamber 21, the oxygen-enriched gas can enter the cooking chamber 21 through the gas delivery member 42 to provide the oxygen-enriched gas for the cooking process. The air outlet 411 of the air pump 41 is communicated with the cooking chamber 21 through the delivery pipe 421, thereby making the communication between the air pump 41 and the cooking chamber 21 more flexible and convenient.

It will be appreciated that the delivery tube 421 can be extended into any position in the cooking chamber 21 as desired by adjusting the length and extending direction of the delivery tube 421. Preferably, referring to fig. 1 and 3, the distance H between the other end (the lower end as shown in fig. 1 and 3) of the delivery pipe 421 and the bottom wall of the cooking cavity 21 satisfies the following relation: h is more than or equal to 2mm and less than or equal to 10 mm. That is, the distance H between the other end (the lower end as shown in fig. 1 and 3) of the delivery pipe 421 and the bottom wall of the cooking cavity 21 is not less than 2mm at the minimum and not more than 10mm at the maximum, for example, 2mm, 3mm, 3.5mm, 5mm, 8mm or 10mm, so that the oxygen supply device 4 can supply oxygen to the cooking cavity 21 to contact with food in the cooking cavity 21 more sufficiently, the cooking effect is better, and the cooked food is more delicious.

Alternatively, the delivery pipe 421 includes a plurality of delivery pipes 421, and the other ends (the lower ends as shown in fig. 1 and 3) of the plurality of delivery pipes 421 are spaced apart from each other, for example, the other ends of the plurality of delivery pipes 421 are evenly spaced apart in the circumferential direction. Therefore, the oxygen supply device 4 can supply oxygen-enriched gas to the cooking cavity 21 to be distributed more uniformly in the cooking cavity 21, the gas is more fully contacted with food in the cooking cavity 21, the cooking effect is better, and the cooked food is more delicious.

It is to be noted that, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

According to an embodiment of the present invention, the air pump 41 can be disposed at the bottom of the cover 3, the bottom or the side of the pot body 1. It should be understood that the air pump 41 can be disposed at a position sufficient for sucking and transferring the oxygen-enriched gas to one end of the gas delivery member 42, and other positions inside/outside the cooking appliance 100 can be used for disposing the air pump 41, which will not be described in detail herein.

In an alternative embodiment of the present invention, as shown in fig. 5 to 9, the gas delivery member 42 includes a delivery pipe 421 and an extension member 422, the extension member 422 is located in the cooking chamber 21, both ends of the delivery pipe 421 are respectively connected to the gas outlet 411 of the gas pump 41 and the extension member 422 to deliver the gas output from the gas pump 41 into the extension member 422, and the extension member 422 is provided with a plurality of ventilation holes 420 communicating with the cooking chamber 21 for releasing the gas delivered into the extension member 422 into the cooking chamber 21. Preferably, the plurality of airing holes 420 are uniformly distributed. Specifically, one end (upper end as shown in fig. 5 to 9) of the delivery pipe 421 is connected to the outlet 411 of the air pump 41, the other end (lower end as shown in fig. 5 to 9) of the delivery pipe 421 is connected to the extension member 422, the delivery pipe 421 is used for delivering the oxygen-containing gas output from the air pump 41 into the extension member 422, the extension member 422 is in contact with the cooking food material, and the extension member 422 uniformly delivers the oxygen-containing gas into the cooking food material through the plurality of ventilation holes 420, so that the cooking food material is sufficiently contacted with the oxygen-containing gas. Wherein the cooking food material should be placed in the cooking cavity 21.

Optionally, the extending members 422 include a plurality of extending members 422, the gas pumped by the gas pump 41 is distributed into the extending members 422 through the delivery pipe 421, and the extending members 422 may be disposed at different positions, so that the oxygen-containing gas can be delivered to a plurality of areas in the cooking cavity 21 through the extending members 422, thereby effectively increasing the contact area between the cooking food and the oxygen-containing gas, achieving uniform oxygenation of the cooking food, and avoiding partial areas from being contactable by the oxygen-free food.

Further, the extension member 422 is rotatably provided in the cooking chamber 21, and the driver 43 for driving the extension member 422 to rotate is electrically connected to the controller 5 so that the extension member 422 rotates under the control of the controller 5. The driver 43 may be a motor, and the driver 43 is connected to the controller 5 to control the start and stop of the driver 43 by the controller 5, so as to control the rotation of the extending member 422. Through extension 422 rotation, can evenly carry oxygen-containing gas in the culinary art edible material, simultaneously because extension 422 rotates it and has stirring effect to the culinary art edible material to make oxygen and culinary art edible material contact more abundant.

The shape of the extension 422 may be arbitrarily selected, and may be formed into a square shape, a rectangular parallelepiped shape (as shown in fig. 5), a spherical shape, an ellipsoidal shape, or the like, for example.

Preferably, as shown in fig. 6 to 9, the extension member 422 is formed as an impeller 422, the impeller 422 includes a plurality of blades 4221 spaced apart in a circumferential direction, and each blade 4221 is provided with at least one ventilation hole 420. When the impeller 422 rotates, the stirring action force of the impeller 422 on the cooked food materials is large, the stirring effect is good, and therefore the contact between oxygen and the cooked food materials is more sufficient.

The extension member 422 further comprises a connecting disc 4222, a plurality of blades 4221 are connected to the outer circumferential edge of the connecting disc 4222 at intervals, and the delivery pipe 421 is connected with the connecting disc 4222, so that the connection between the delivery pipe 421 and the blades 4221 is realized, and the connection is convenient. As shown in fig. 7 and 9, the coupling plate 4222 defines therein a main flow passage 42221 communicating with the other end (lower end as shown in fig. 7 and 9) of the delivery pipe 421, each of the blades 4221 is formed with a branch flow passage 42211 communicating with the main flow passage 42221, and the air holes 420 of each of the blades 4221 are respectively communicated with the branch flow passages 42211 of the corresponding blade 4221, so that the oxygen-enriched gas output from the air pump 41 first enters the main flow passage 42221 through the delivery pipe 421, then flows into the plurality of branch flow passages 42211, and finally flows into the cooking chamber 21 through the plurality of air holes 420.

Further, as shown in fig. 7 and 9, the airing holes 420 are formed on the upper surface of the vane 4221, so that the oxygen-rich gas is more sufficiently contacted with the cooking food material, and the cooking effect is better. Of course, the present application is not limited thereto, and the airing holes 420 may be formed on the lower surface or the sidewall of the leaves 4221

It will be appreciated that the extension 422 should be positioned at a lower-middle portion within the cooking chamber 21 to facilitate the rising of the gas after entering the cooking chamber 21, increasing the chance of contact with the food during the rising. Among them, the ventilation holes 420 of the extension member 422 should be provided such that air can be discharged only by the air pump 41 and food cannot enter the extension member 422 therethrough, for example, a check valve or the like is provided. Further, the extension 422 may be provided at a position 2mm to 10mm from the bottom of the cooking chamber 21 so that the gas can be rapidly diffused through the distance after entering the cooking chamber 21.

It should be understood that the extension 422 can be in one or more combinations in a cooking apparatus 100, and the extension 422 can also be in other devices capable of assisting the oxygen-containing gas to contact the cooking food material uniformly and uniformly, and will not be described in detail herein.

It should be noted that the air pump 41 and the air delivery member 42 can be detachably connected, for example, in the example shown in fig. 1-2, the air pump 41 and the delivery tube 421 can be connected in a pluggable manner, and the air pump 41 and the delivery tube 421 can be conveniently detached; as shown in fig. 3-4, the air pump 41 is connected to the delivery tube 421 by a screw, and the connection between the air pump 41 and the delivery tube 421 is stable and reliable, and is easy to assemble and disassemble. By the detachable connection between the air pump 41 and the air delivery member 42, the air delivery member 42 can be detached separately for cleaning after cooking, thereby facilitating the cleaning of the air delivery member 42. Moreover, the gas delivery member 42 may not be installed when oxygen-enriched cooking is not required, thereby satisfying various cooking requirements of users.

Further, the extension pieces 422 can be detachably connected to the delivery pipe 421, for example, the extension pieces 422 can be screwed or detachably connected to the delivery pipe 421. Thus, after cooking is finished, the user can detach the delivery pipe 421 and the extension member 422 respectively for cleaning, so as to ensure cleanness in the next cooking. Of course, the extension pieces 422 and the delivery pipe 421 may be non-detachably connected, such as integrally formed or welded.

In an alternative example, the delivery pipe 421 and the extension member 422 are fixedly connected, the driver 43 is connected to the delivery pipe 421, and the extension member 422 is rotated by driving the delivery pipe 421, in which case the delivery pipe 421 is preferably formed into a rigid pipe, such as a steel pipe. It should be noted that, the fixed connection between the delivery pipe 421 and the extension member 422 means that the delivery pipe 421 and the extension member 422 are relatively static, no relative movement occurs between the delivery pipe 421 and the extension member 422, and the driver 43 is connected to the delivery pipe 421, and drives the extension member 422 to rotate by driving the delivery pipe 421 to rotate, thereby facilitating the connection.

Further, as shown in fig. 6, 8 and 10, an air pump 41 is provided between the driver 43 and the delivery pipe 421, and the driver 43 is connected to the delivery pipe 421 through the air pump 41. Specifically, the driver 43 is connected to the air pump 41 to drive the air pump 41 to rotate, the delivery pipe 421 is fixedly connected to the air pump 41, and the delivery pipe 421 rotates synchronously with the air pump 41. It should be noted that the fixed connection between the delivery tube 421 and the air pump 41 means that the delivery tube 421 and the air pump 41 are relatively stationary, and the relative position between the delivery tube 421 and the air pump 41 is kept unchanged. The driver 43 is connected to the delivery tube 421 through the air pump 41 to rotate the delivery tube 421, so that the connection between the driver 43, the air pump 41 and the delivery tube 421 is simpler. The fixed connection between the delivery pipe 421 and the air pump 41 can be realized by the fixed connection between the delivery pipe 421 and the air outlet 411 of the air pump 41.

The air pump 41 is connected to the power source through the power connection line, and in the above embodiment, since the air pump 41 and the delivery pipe 421 rotate synchronously, in order to avoid the winding phenomenon of the power connection line, the power connection line is rotatably connected to the air pump 41, so that the winding phenomenon of the power connection line can be avoided.

Of course, the present application is not limited thereto, and the driver 43 and the delivery pipe 421 can be directly connected to drive the delivery pipe 421 to rotate, i.e. the connection between the driver 43 and the delivery pipe 421 is not through an intermediate connection of the air pump 41, and the connection manner is more diversified. And at this time, the air pump 41 may not rotate in synchronization with the delivery pipe 421, thereby preventing the power connection line from being twisted.

As shown in fig. 10, the mounting chamber 31 is defined in the cover body 3, the air pump 41 and the driver 43 are provided in the mounting chamber 31, and the mounting chamber 31 is isolated from the cooking chamber 21, thereby preventing steam in the cooking chamber 21 from entering the mounting chamber 31 to damage the air pump 41 and the driver 43. Further, in the example shown in fig. 6 to 10, the air source is air in the external environment of the cooking appliance 100, the mounting cavity 31 has a communication hole 311 communicated with the external environment, the air in the external environment enters the mounting cavity 31 through the communication hole 311, and the air entering the mounting cavity 31 is delivered into the cooking cavity 21 through the gas delivery member 42 by the air pump 41.

With continued reference to the example shown in fig. 6-10, the installation cavity 31 has a through hole, the delivery pipe 421 passes through the through hole and extends into the installation cavity 31 to connect with the air outlet 411 of the air pump 41 located in the installation cavity 31, a shaft sleeve is arranged between the delivery pipe 421 and the through hole, by arranging the shaft sleeve, not only can abrasion between the delivery pipe 421 and the through hole when rotating be avoided, but also the effect of sealing a connecting gap between the delivery pipe 421 and the through hole is achieved, and therefore the steam in the cooking cavity 21 is better prevented from entering the installation cavity 31 to influence the operation of the driver 43 and the air pump 41.

Further, as shown in fig. 10, the lid body 3 is provided with a grip portion 32, and at least a part of the mounting cavity 31 is formed in the grip portion 32, whereby it is possible to avoid the mounting cavity 31 from excessively protruding. Of course, the installation positions of the driver 43 and the air pump 41 are not limited to this, and the installation positions of the driver 43 and the air pump 41 can be arbitrarily selected according to actual needs. For example, the driver 43 and the air pump 41 may be provided on the bottom or side of the pot body 1.

In the above embodiment, as shown in fig. 1, 3, 6 and 8, the gas conveying member 42 extends into the cooking cavity 21 from the open port of the cooking cavity 21 from top to bottom, but the present invention is not limited thereto, and the gas conveying member 42 may also extend into the cooking cavity 21 from bottom to top through the bottom wall of the inner container 2; or the gas delivery member 42 extends from the side peripheral wall of the inner container 2 into the cooking chamber 21.
