As used in the description of the present application, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 6, the present application provides a frying and baking machine, which includes a frying and baking machine main body 100, a water tank assembly 30 and a steam generator 50. The main body 100 has a cooking cavity 102, and the water tank assembly 30 has a water storage cavity 311. The steam generator 50 has a steam generation chamber 501 communicated with the cooking chamber 102, the steam generation chamber 501 is communicated with the water storage chamber 311 through a connection pipe 40, the connection pipe 40 is arranged below the water tank assembly 30, and the first end 41 of the connection pipe 40 far away from the water tank assembly 30 extends into the steam generation chamber 501. At least a portion of the bottom wall of the steam generating chamber 501 is higher than the end surface of the first end 41 in the vertical direction so that the upper portion of the steam generating chamber 501 is always in gas communication with the cooking chamber 102. It is understood that "the upper portion of the steam generating chamber 501 is always in gas communication with the cooking chamber 102" means that the gas between the upper portion of the steam generating chamber 501 and the cooking chamber 102 is communicated so that the gas pressure of the upper portion of the steam generating chamber 501 is equal to the gas pressure in the cooking chamber 102. When the steam-generating device is used, the water storage cavity 311 is firstly sealed, so that the water storage cavity 311 forms a sealed space, and the water level in the steam-generating cavity 501 can be controlled by utilizing the air pressure in the cooking cavity 102. Particularly, because the connecting pipe 40 sets up in water tank set 30 below, and the first end 41 that the connecting pipe 40 is kept away from water tank set 30 stretches into in the steam generation chamber 501, therefore, when the water level in the steam generation chamber 501 is less than the terminal surface of first end 41, the air in the steam generation chamber 501 can follow connecting pipe 40 and get into water storage chamber 311, thereby atmospheric pressure in the water storage chamber 311 equals with the atmospheric pressure in the steam generation chamber 501, water can flow to the steam generation chamber 501 under self action of gravity, thereby the water level in the steam generation chamber 501 constantly rises. Since the upper portion of the steam generation cavity 501 is always in gas communication with the cooking cavity 102, and the air pressure of the upper portion of the steam generation cavity 501 is equal to the air pressure in the cooking cavity 102, when the water level in the steam generation cavity 501 is higher than the end surface of the first end 41, the air in the steam generation cavity 501 cannot continuously enter the water storage cavity 311 from the connection pipe 40, and thus the air pressure in the water storage cavity 311 is reduced. When the water pressure at the water level is equal to the air pressure at the upper portion of the steam generation chamber 501 (i.e., the air pressure in the cooking chamber 102), the water in the water storage chamber 311 cannot continuously flow to the steam generation chamber 501, and thus the water level in the steam generation chamber 501 is maintained at the preset position. That is, the air pressure inside the cooking chamber 102 may control the water level inside the steam generation chamber 501. When steam is to be generated, it is only necessary to heat the water in the steam generating chamber 501 to boiling, rather than heating the entire water in the water tank assembly 30, so that the toaster can generate steam more quickly and deliver it to the cooking chamber 102. Therefore, compared with the frying and baking machine which needs to heat all water, the frying and baking machine greatly shortens the time of steam discharging. And along with the continuous production of steam, the water level in the steam generation chamber 501 will constantly descend, and when the water level descends to the terminal surface below of first end 41, the air on steam generation chamber 501 upper portion again gets into water storage chamber 311 through connecting pipe 40 to the water in the water storage chamber 311 again supplements to the steam generation chamber 501, thereby makes the fixed water level in the steam generation chamber 501 remain throughout, and then steam generator 50 can constantly produce steam and carry to culinary art chamber 102.

Further, a water level groove 502 is formed between the outer wall of the first end 41 and the inner wall of the steam generating chamber 501 at an interval, and the water level groove 502 is always in gas communication with the cooking chamber 102. Because the water level groove 502 is formed between the outer wall of the first end 41 and the inner wall of the steam generation cavity 501, when the water level in the cooking cavity 102 rises to the end surface of the first end 41, air in the water level groove 502 cannot be discharged, so that the water level groove 502 and the cooking cavity 102 can be always kept in gas communication, namely the upper part of the steam generation cavity 501 and the cooking cavity 102 are always kept in gas communication, and the water level in the steam generation cavity 501 can be controlled to be at a preset position by utilizing the air pressure in the cooking cavity 102.

Referring to fig. 1, the main body 100 of the frying and roasting machine includes a base assembly 10 and a cover assembly 20, wherein the cover assembly 20 is rotatably connected to the base assembly 10.

Referring to fig. 3, the base assembly 10 includes a lower baking tray 12, a bottom casing 11 and a lower heating member 13, the lower baking tray 12 is installed inside the bottom casing 11, and the lower heating member 13 is disposed at the bottom of the lower baking tray 12 for heating the lower baking tray 12. In one embodiment, the lower heating member 13 is a heating pipe attached to the bottom of the lower grill 12, so that the lower grill 12 is heated by direct heat transfer.

Referring to fig. 3, the upper cover assembly 20 includes an upper grill pan 22 and an upper housing 21, and the upper grill pan 22 is disposed inside the upper housing 21. When the upper cover assembly 20 is covered on the base assembly 10, the upper roasting pan 22 and the lower roasting pan 12 are matched to form a cooking cavity 102. In this way, when the cover is closed for cooking, the cooking cavity 102 forms a relatively closed space, so that the food can be humidified by adding steam into the cooking cavity 102, and the food can be prevented from being fried and baked too dry. It is understood that the phrase "the cooking cavity 102 forms a relatively closed space" means that the cooking cavity 102 is not an absolutely closed space, and there may be a gap between the upper roasting pan 22 and the lower roasting pan 12, and the steam in the cooking cavity 102 may leak outwards, thereby avoiding the over-high pressure in the cooking cavity 102.

Further, the upper cover assembly 20 further comprises an upper heating member 23, and the upper heating member 23 is used for heating the upper roasting pan 22. In this embodiment, the upper heating member 23 is a heating pipe, and the upper heating member 23 is disposed adjacent to the upper grill pan 22, so as to facilitate direct heat transfer to the upper grill pan 22.

In this embodiment, an upper cover cavity 201 is defined between the upper casing 21 and the upper baking tray 22, the steam generator 50 is disposed in the upper cover cavity 201, and when the upper cover 20 covers the base assembly 10, at least a portion of the steam generator 50 is located below the water tank assembly 30. Thus, the water in the water tank assembly 30 flows into the steam generator 50, and the space below the water tank assembly 30 is reasonably utilized, so that the structure is more compact. In this embodiment, the steam generator 50 is integrally located below the water tank assembly 30, so that the structure is more compact.

Referring to fig. 4, 9 and 10, the upper housing 21 is recessed toward the upper grill pan 22 to form a mounting groove 211, and the water tank assembly 30 is mounted in the mounting groove 211. The groove bottom of the mounting groove 211 is provided with a connecting port 212, the connecting pipe 40 is arranged around the outer side of the connecting port 212 and extends towards the upper roasting tray 22, and the connecting pipe 40 is communicated with the water storage cavity 311 through the connecting port 212. In this way, water in the water storage cavity 311 can enter the connection pipe 40 through the connection port 212 and enter the steam generation cavity 501 through the connection pipe 40, and thus the water is heated in the steam generation cavity 501 to form steam, and finally the steam is delivered to the cooking cavity 102. In this embodiment, the connecting tube 40 and the upper case 21 are an integral structure. But not limited thereto, in other embodiments, the connection pipe 40 may be directly connected to the water tank assembly 30.

Further, the steam generator 50 is located between the bottom of the mounting groove 211 and the upper grill pan 22, so that the space between the bottom of the mounting groove 211 and the upper grill pan 22 is reasonably utilized, and the structure is more compact.

The present application provides that the water tank assembly 30 and the steam generator 50 are both mounted on the upper cover assembly 20, but not limited thereto, the water tank assembly 30 and the steam generator 50 may also be mounted on the base assembly 10, as long as the steam generator 50 is located below the water tank assembly 30, the water in the water tank assembly 30 can flow to the steam generator 50, and steam can be generated by heating the steam generator 50. It should be understood that in the present embodiment, the water tank assembly 30 and the steam generator 50 are mounted to the lid assembly 20, and therefore, the terms "upper" and "lower" are used herein with reference to the orientation of the lid assembly 20 when it is attached to the base assembly 10.

Referring to fig. 4, 6, 7 and 8, in one embodiment, the steam generator 50 includes a connector 51 and a steam generating pipe 52, the connector 51 is provided with a first inner cavity 511, and the first inner cavity 511 has a first opening 512 and a second opening 513. The first end 41 of the connection pipe 40 extends into the first inner cavity 511 through the first opening 512, and the portion of the first inner cavity 511 located outside the connection pipe 40 forms the water level tank 502. One end of the steam generating pipe 52 is communicated with the first inner cavity 511 through the second opening 513, the steam generating pipe 52 is provided with a second inner cavity 521, and the second inner cavity 521 and the first inner cavity 511 together form the steam generating cavity 501. The upper portion of the first inner chamber 511 and the upper portion of the second inner chamber 521 are in gas communication with the cooking chamber at all times. In this way, the water in the steam generating cavity 501 can be heated to form steam by the heating connector 51 or the steam generating pipe 52, so that the installation position of the steam generator 50 in the main body 100 of the grill can be more flexibly arranged.

Referring to fig. 8, the first opening 512 is disposed on the top wall of the connecting head 51, the second opening 513 is disposed on the side wall of the connecting head 51, and the first end 41 of the connecting tube 40 is located at one side of the second opening 513. In this way, the water in the water storage chamber 311 first flows into the first inner chamber 511 of the connection head 51 through the connection pipe 40, when the water level reaches the second opening 513, the water flows into the second inner chamber 521 through the second opening 513, and then the water levels in the first inner chamber 511 and the second inner chamber 521 rise synchronously. Since the first end 41 of the connection pipe 40 is located at the side of the second opening 513, when the water level reaches the end position and above the first end 41, the air in the first inner chamber 511 cannot enter the water storage chamber 311 through the connection pipe 40, thereby facilitating the upper portion of the first inner chamber 511 to maintain the air communication with the cooking chamber 102.

Referring to fig. 6, further, at least a portion of the bottom wall of the second inner cavity 521 is higher than the end surface of the first end 41. In this way, it is ensured that the second inner chamber 521 is not completely filled with water, but there is a space for the upper part to be in gas communication, ensuring that both the upper part of the first inner chamber 511 (i.e. the water level tank 502) and the upper part of the second inner chamber 521 are in gas communication with the cooking chamber 102 at all times.

The steam generating pipe 52 includes an inlet end 522 and an outlet end 523, the inlet end 522 is connected to the second opening 513, the main body 100 of the frying and baking machine is provided with a steam outlet 221 communicated with the cooking cavity 102, in this embodiment, the upper baking tray 22 is provided with a steam outlet 221 communicated with the cooking cavity 102, and the outlet end 523 is connected to the steam outlet 221. From the inlet end 522 towards the outlet end 523, the steam generating channels 52 include at least portions that extend upwardly and then turn downwardly, with at least the turn portions of the steam generating channels 52 being higher than the end faces of the first ends 41. In this way, the steam generating channel 52 extends upward to make the steam generating channel 52 at least partially higher than the end surface of the first end 41, so that it is ensured that the water in the steam generating channel 52 does not fill the entire second inner chamber 521, but there is a space for gas to flow through. The downwardly extending arrangement of the steam generating channel 52 facilitates the communication of the steam generating channel 52 with the cooking chamber 102, so that the steam generated by heating the water in the steam generating channel 52 can smoothly flow toward the cooking chamber 102.

Further, the steam generating pipe 52 is at least partially abutted against the heating member (the upper heating member 23 or the lower heating member 13) to heat the steam generating pipe 52 by the heating member, so that the water in the second inner chamber 521 is heated and boiled to generate steam, and the steam flows toward the cooking chamber 102 through the steam outlet 221. Thus, the heating member heats the steam generating pipe 52 when heating the roasting tray (the upper roasting tray 22 or the lower roasting tray 12), that is, the heating member simultaneously plays a role of heating the roasting tray and the steam generating pipe 52, thereby reducing the number of parts and simplifying the structure of the frying and roasting machine. Referring to fig. 1 to 6, in the present embodiment, the steam generating pipe 52 is at least partially abutted against the upper heating member 23 to heat the steam generating pipe 52 by the upper heating member 23. In this embodiment, the upper heating member 23 simultaneously heats the upper grill 22 and the steam generating pipe 52, so as to reduce the number of parts and simplify the structure of the grill machine. Without limitation, in embodiments (not shown) in which the steam generator 50 is disposed on the base assembly 10, the steam generating channel 52 may be disposed at least partially against the lower heating member 13 such that the steam generating channel 52 is heated by the lower heating member 13. In this way, the lower heating member 13 serves to heat the lower grill pan 12 and the steam generating pipe 52 at the same time, so that the structure of the grill machine can be simplified as well. In this embodiment, the upper heating member 23 heats the steam generating pipe 52, but is not limited thereto, and the upper heating member 23 may also heat the connector 51. In other words, as long as the steam generator 50 is at least partially attached to the upper heating member 23, the steam generator 50 can be heated by the upper heating member 23, so that the upper heating member 23 can simultaneously perform the functions of heating the upper grill pan 22 and heating the steam generator 50, thereby simplifying the structure. Because the water in the steam generator 50 is less, the steam generator can be heated and boiled quickly to generate steam, so that the time for generating the steam is greatly shortened, and the water level in the steam generating chamber 501 is lowered continuously along with the continuous generation of the steam. As the water level decreases, the water in the water storage chamber 311 is continuously replenished into the steam generating chamber 501, and the amount of water in the steam generating chamber 501 is maintained.

Referring to fig. 6 to 8, in the present embodiment, the steam generating pipe 52 further includes a heated section 525 extending along the horizontal direction, and the heated section 525 extends along the upper heating member 23 and is attached to the upper surface of the upper heating member 23. Thus, the steam generating tube 52 has a large contact area with the upper heating member 23, so that the steam generating tube 52 can be heated more quickly to generate steam, improving the efficiency of steam generation. Of course, in the embodiment (not shown) in which the steam generator 50 is disposed on the base assembly 10, the heated section 525 of the steam generating tube 52 may extend along the lower heating member 13 and abut against the lower surface of the lower heating member 13, so that the steam generating tube 52 has a larger contact area with the lower heating member 13, and thus the steam generating tube 52 can be heated more quickly to generate steam, which improves the efficiency of steam generation.

Referring to fig. 2 and 7, in the present embodiment, from the inlet end 522 to the outlet end 523, the steam generating tubes 52 extend a certain length in the horizontal direction, then extend obliquely upward, and then turn to extend downward to the steam outlet 221. Wherein the portion of the steam generating channel 52 extending in the horizontal direction includes the heated section 525. Further, the portions of the steam generating channels 52 extending in the horizontal direction are not on the same vertical plane, that is, the steam generating channels 52 may extend in any direction along the horizontal plane, as shown in fig. 2 and 7, and the steam generating channels 52 change direction in the horizontal plane through two right-angled corners, so that the installation positions of the steam generator 50 can be more reasonably arranged. Of course, this is only one example, and the steam generating channels 52 may be extended in a horizontal direction in various ways, which is not limited in this application.

Referring to fig. 1 and 7, further, the steam generating pipe 52 is fixed to the upper grill pan 22 by a mounting clip 53.
