Description

Technical Field

[0001] The present application relates to the field of small household appliances, and in particular to a frying and grilling machine. Background Art

[0002] The grilling machine places the food on the grilling tray and heats the grilling tray through the heating tube to achieve the effect of cooking the food. Because the heating tube will generate a high temperature, if the food is directly placed on the grilling tray for high temperature heating, the food will easily become dry and difficult to chew due to the dry environment and low humidity in the cooking chamber of the grilling machine.

[0003] In order to increase the humidity in the cooking cavity and prevent the food from becoming dry and woody, a steam groove is provided on the baking tray. Liquid is added to the steam groove. When the heating tube heats the baking tray, it also heats the steam groove, thereby generating steam that enters the cooking cavity, increasing the humidity in the cooking cavity, thereby making the food fresh and tender (juicy).

[0004] As in the prior art, Chinese utility model patent CN218009387U, two symmetrical outwardly protruding first sink grooves (equivalent to the steam grooves of the present application) are arranged on the edge of the baking tray, and a steam channel is opened on the side panel (the side panel is equivalent to the first side and the second side of the present application). During operation, the heating pipe heats the steam groove, and the generated steam enters the cooking cavity through the steam channel, thereby increasing the humidity in the cooking cavity.

[0005] However, by providing a notch on the second side to allow the steam in the steam groove to enter the cooking cavity, the speed of the water vapor entering the cooking cavity is slow, so that the water vapor entering the cooking cavity accumulates in the area near the steam groove, so that the part of the food near the steam groove becomes soft and sticky because it is in contact with more water vapor, while the part far from the steam groove becomes dry and tough because the water vapor cannot reach this part. The food cannot have a fluffy and tender taste, and the taste of the food cooked in the same pot is different, and a good cooking effect cannot be achieved. Summary of the invention

[0006] In order to solve the above technical problems, the present application discloses a grilling machine, which provides a recessed section at the first side so that most of the steam enters the cooking cavity from the recessed section, thereby increasing the speed at which the steam enters the cooking cavity and allowing the steam to completely cover the cooking cavity.

[0007] The present application discloses a grilling machine, comprising a lower grilling pan for cooking food, and an upper grilling pan assembly covering the lower grilling pan to form a cooking cavity, wherein a steam groove is arranged on the lower grilling pan to provide water vapor to the cooking cavity, and the lower grilling pan comprises a grilling pan body and side edges arranged around the lower grilling pan body, wherein the side edges comprise: a first side edge; a second side edge, wherein the first side edge, the second side edge and the lower grilling pan body are enclosed to form a grilling area, wherein the lowest point of the second side edge is greater than or equal to the highest point of the first side edge; and a third side edge, which is located outside the second side edge, wherein the third side edge and the second side edge are enclosed to form a steam groove, wherein a recessed section is arranged at a position of the first side edge adjacent to the second side edge, and the steam groove provides water vapor to the cooking cavity through the recessed section.

[0008] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0009] Optionally, the top surface of the recessed section is inclined from the inner wall of the side toward the steam groove.

[0010] Optionally, one recessed section is respectively provided at both ends of the second side edge.

[0011] Optionally, the second side is provided with an inclined section, and the inclined section includes at least one first inclined section whose height gradually increases, and at least one second inclined section whose height gradually decreases.

[0012] Optionally, the first inclined section and the second inclined section are provided singly.

[0013] Optionally, a connecting hole is opened on the inclined section, and the connecting hole is used to pass through the steam groove and the cooking cavity.

[0014] Optionally, a blocking wall extends upward from the third side, and a height of the blocking wall is greater than a height of the first side.

[0015] Optionally, the upper grill assembly includes an annular rib extending into the grilling area, and an air transmission channel is formed between the annular rib and the second side edge to guide steam from the steam groove into the cooking cavity.

[0016] Optionally, the upper baking tray assembly includes an upper cover, and the upper cover includes a cover plate arranged above the steam groove and spaced apart from the steam groove.

[0017] Optionally, the upper grilling pan assembly is connected to the lower grilling pan assembly of the grilling machine via a hinge device, and the steam groove is arranged on a side close to the hinge device.

[0018] In the grilling machine of the present application, since the lowest point of the second side is greater than or equal to the highest point of the first side, the second side blocks the movement of steam, causing the steam to move to both sides of the second side. A recessed section is provided at the first side adjacent to the second side. When the steam moves to both sides of the second side and reaches the recessed section, the steam enters the cooking cavity through the recessed section, thereby achieving the effect of the steam quickly entering the cooking cavity and the purpose of the steam being able to completely cover the cooking cavity.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] The grilling machine 100 includes an upper grill assembly 200 and a lower grill assembly 300. Before cooking food, the user opens the upper grill assembly 200 and the lower grill assembly 300, places the food on the lower grill assembly 300 (it can also be placed on the upper grill assembly 200, which is not illustrated here), then covers the upper grill assembly 200 and the lower grill assembly 300, and uses a heating tube to heat the lower grill assembly. The heat of the heating tube is transferred to the lower grill assembly, and the lower grill assembly heats the food.

[0036] Due to cost saving and manufacturing process limitations, the heating tubes on the existing grilling machine 100 are not evenly and densely distributed, but are mostly distributed in a special shape (such as a G shape or an Ω shape). Therefore, the heating tubes heat the lower grilling plate unevenly, and the temperature of each area on the lower grilling plate is not isothermally distributed. The grilling machine 100 cannot fully and evenly heat the food, resulting in a poor texture and taste of the food. In order to improve the adequacy of the heating tube heating the baking tray and change the taste of food, the prior art solves the technical problem through different technical routes: one way is to add a reflective cover between the lower baking tray and the base, and the heating tube is arranged between the reflective cover and the lower baking tray, so that the heat of the heating tube will be reflected to the lower baking tray through the reflective cover, which can not only make the heat generated by the heating tube be used more for heating the baking tray, but also make the heat of the baking tray more uniform, thereby changing the taste of food; another way is to add a steam groove 301 on the lower baking tray, and heat the liquid in the steam groove 301 through the heating tube to generate water vapor, and the water vapor enters the cooking cavity, the food can not only obtain heat from the heated water vapor, thereby realizing rapid heating of the food, but also the water vapor can increase the humidity of the cooking cavity, effectively improving the dry and high temperature environment in the original cooking cavity due to the excessive temperature, so that the prepared food can achieve a fluffy and tender taste.

[0037] As mentioned above, a grilling machine 100 of the present application includes a lower grilling plate for cooking food, and an upper grilling plate assembly 200 covering the lower grilling plate to form a cooking cavity, a steam groove 301 is arranged on the lower grilling plate to provide water vapor to the cooking cavity, the lower grilling plate includes a grilling plate body and a side 401 arranged around the lower grilling plate body, the side 401 includes: a first side 402; a second side 403, the first side 402, the second side 403 and the lower grilling plate body are enclosed to form a grilling area 405, the lowest point of the second side 403 is greater than or equal to the highest point of the first side 402; a third side 404, located on the outer side of the second side 403, the third side 404 and the second side 403 are enclosed to form the steam groove 301, a recessed section 406 is arranged at the first side 402 adjacent to the second side 403, and the steam groove 301 provides water vapor to the cooking cavity through the recessed section 406. In the prior art, the steam tank 301 is usually set to have the second side 403 of the steam tank 301 lower than the first side 402. In this way, after the steam tank 301 is heated, an equal amount of water vapor is uniformly generated in the steam tank 301, and the second side 403 is set to be equal in height, and the height difference between the second side 403 and the first side 402 is equal and constant, so the water vapor will naturally move from the second side 403 by inertia, and enter the cooking cavity. This setting will make the initial speed of the water vapor entering the cooking cavity smaller, so that the water vapor is easy to accumulate in the area near the steam tank 301 after entering the cooking cavity, so that the food near the steam tank 301 area becomes soft and sticky due to absorbing more water vapor, and the food far from the steam tank 301 area becomes dry, hard and woody due to not being able to contact with the water vapor or only contacting less water vapor. In order to make the food made by the frying and grilling machine 100 have a fluffy and tender taste, the taste of the food made in the same pot is also uniform.

[0038] In this embodiment, reference Figure 1 , Figure 3 and Figure 4 As shown, the side edge 401 extends along the axial direction of the grilling machine 100, and the side edge 401 cooperates with the lower grill body to form a lower grill with a certain depth, so that during cooking with the lower grill, the side edge 401 can prevent food from sliding to the outside of the lower grill, and can also use the lower grill with a certain depth to cook food with soup. At the same time, when the upper grill assembly 200 and the lower grill assembly 300 are covered with each other, the upper grill assembly 200 can be closely matched with the side edge 401 to form a cooking cavity, and the close fit between the upper grill assembly 200 and the side edge 401 can prevent the heat generated by the heating tube from overflowing to the outside, and can also allow the water vapor to fully contact with the food in the cooking cavity.

[0039] Water vapor enters the cooking cavity from the steam groove 301 to achieve a moisturizing effect on the food. In order to increase the initial speed of water vapor entering the cooking cavity from the steam groove 301, the lowest point of the second side 403 is greater than or equal to the highest point of the first side 402. That is, the height of the second side 403 is higher than the height of the first side 402, and the gap between the second side 403 and the upper grill assembly 200 is smaller than the gap between the two in the prior art, or the second side 403 and the upper grill assembly 200 are close to each other in some areas. When water vapor is generated in the steam groove 301, the water vapor rises along the direction of the second side edge 403. In the area with a smaller gap between the second side edge 403 and the upper baking tray assembly 200, the speed at which water vapor enters the cooking cavity from the steam groove 301 is lower than the speed at which water vapor is generated. On the one hand, the generated water vapor will squeeze the water vapor entering the cooking cavity in this area, thereby accelerating the speed at which water vapor enters the cooking cavity. On the other hand, excess water vapor that cannot quickly enter the cooking cavity from this area will move to other areas with a relatively larger gap between the second side edge 403 and the upper baking tray assembly 200, which will increase the amount of water vapor in the area with a relatively larger gap, thereby also increasing the speed of water vapor in the area with a relatively larger gap.

[0040] In the prior art, the second side 403 that forms the steam groove 301 is lower than the first side 402. In this way, during the cooking process, oil stains or food residues will enter the steam groove 301, which will inhibit the speed and amount of water vapor generated in the steam groove 301, and will increase the dirt in the steam groove 301, increasing the difficulty of cleaning the steam groove 301. Therefore, in the present application, the lowest point of the second side 403 is greater than or equal to the highest point of the first side 402, which can prevent oil stains and food residues from entering the steam groove 301, thereby ensuring the speed and amount of water vapor generated in the steam groove 301.

[0041] At the same time, if less water vapor enters the cooking cavity in the same time period, the water vapor cannot quickly fill the entire cooking cavity, so that the humidity in each area of ​​the food is difficult to reach uniformity in a short time, so that the humidity in each area is different, which will make the taste of the food cooked in the same pot different. In order to increase the amount of water vapor entering the cooking cavity without affecting the speed of water vapor entering the cooking cavity, a recessed section 406 is provided at the first side 402 adjacent to the second side 403, and the aperture of the recessed section 406 for water vapor to enter the cooking cavity is small. In this way, not only when the steam groove 301 corresponding to the recessed section 406 generates water vapor, the water vapor can directly flow out from the recessed section 406 and enter the cooking cavity; but also the excess water vapor that cannot enter the cooking cavity from the corresponding area can enter the cooking cavity from the recessed section 406, so that more water vapor can enter the cooking cavity without reducing the speed of water vapor entering the cooking cavity as much as possible, so that the cooking cavity can be quickly filled with water vapor. When using the grilling machine 100 to make pancakes, if the steam groove 301 is disposed inside the grilling machine 100, the grilling area 405 will become irregular in shape. When the food to be made needs to occupy a larger grilling area 405, the irregular grilling area 405 will affect the shape of the food. For example, when making pancakes, if the steam groove 301 is disposed inside the grilling machine 100, the pancakes will be partially covered on the steam groove 301. At this time, one way is to cut the food placed on the steam groove 301, and the food will not be in a regular shape, which affects the user's experience of the grilling machine 100; another way is to directly place the food on the steam groove 301 to heat and humidify the food, so that the part of the food placed on the steam groove 301 will become wet and soft due to contact with more water vapor, and the taste of the other part of the food cannot be consistent; or reduce the size of the food so that the food does not contact the steam groove 301, which will reduce the adaptability of the grilling machine 100 and prevent the grilling machine 100 from cooking more types of food. Therefore, the first side 402, the second side 403 and the lower grill body enclose a grilling area 405, and the grilling area 405 is a regular and symmetrical area. At the same time, the third side 404 is arranged outside the second side 403, so that the steam groove 301 is arranged outside the grilling area 405, so that the pancake food can be completely placed in the grilling area 405, thereby improving the adaptability of the grilling machine 100 to cooking food.

[0042] The function of the recessed section 406 is to allow more water vapor to enter the cooking cavity from the steam groove 301. The recessed section 406 is the lowest point of the side edge 401 of the lower baking pan body. When the recessed section 406 is lower, more water vapor can enter the cooking cavity. The recessed section 406 can be set to a conical, hemispherical or elliptical structure.

[0043] The upper grill assembly 200 and the lower grill assembly 300 of the grilling machine 100 can be hingedly connected by a hinge device 500, or the upper grill assembly 200 and the lower grill assembly 300 can be connected together by buckling.

[0044] However, when the water vapor passes through the concave section 406, it is inevitable that some of the water vapor will be cooled and become small water droplets attached to the concave section 406, and cannot enter the cooking cavity. If the small water droplets cannot be cleaned in time, the small water droplets will gradually accumulate in the concave section 406. When there are many accumulated small water droplets, not only will the small water droplets enter the cooking cavity in the form of cold liquid, affecting the preparation of food; more importantly, when the grilling machine 100 is not in use, the small water droplets in the concave section 406 are prone to breed bacteria and other harmful substances. When it is used again, if the user does not clean it or the cleaning is not thorough enough, the bred bacteria and harmful substances will enter the food, which is easy to cause health problems to the user. At the same time, the storage capacity of the liquid in the steam tank 301 is generally the storage capacity for a single food preparation. When a single food preparation is performed, the water vapor in the steam tank 301 will be completely evaporated by the lower heating tube of the grilling machine 100, and it is not easy for liquid to remain in the steam tank 301; compared with the recessed section 406, the user will also pay more attention to the cleaning of the steam tank 301, and the cleaning of the steam tank 301 is also more convenient and simple. For example, when the user cleans the small water droplets in the recessed section 406, the small water droplets with higher heat are easy to vaporize and burn the user; or because there are many textures or folds in the recessed section 406, it is not easy to clean. Therefore, in order to accumulate small water droplets in the recessed section 406, the top surface of the recessed section 406 is inclined from the inner wall of the side 401 to the direction of the steam tank 301. The inside of the recessed section 406 is an inclined surface inclined toward the steam groove 301. When small water droplets drop into the recessed section 406, due to the effect of gravity, the small water droplets will flow into the steam groove 301 along the inclined direction of the inclined surface, so that the small water droplets are heated again to become water vapor and enter the cooking cavity, reducing the accumulation of small water droplets in the recessed section 406 and effectively preventing the growth of bacteria.

[0045] Only one concave section 406 may be provided at the junction of the first side 402 and the second side 403, so that the water vapor is mainly ejected into the cooking cavity in one direction, so that the cooking cavity is filled with water vapor. However, the single concave section 406 that transports water vapor into the cooking cavity will reduce the amount of water vapor transported per unit time. Moreover, only one concave section 406 is provided, so that the notches for the water vapor to be discharged from the steam groove 301 cannot be distributed symmetrically, thereby causing the water vapor to be turbulent in the steam groove 301, so that some areas of the steam groove 301 have more water vapor, and some areas of the steam groove 301 have less water vapor, and the turbulent water vapor will hinder the speed of the water vapor to be discharged from the steam groove 301 to a certain extent. Therefore, a concave section 406 is provided at each end of the second side 403. When the concave sections 406 are symmetrically provided at the two ends of the second side 403, the water vapor will be ejected into the cooking cavity from the two concave sections 406, which will reduce the degree of turbulence of the water vapor in the steam groove 301. In order to fill the cooking cavity with water vapor more quickly, the steam groove 301 is set to an arc structure, and the concave section 406 is set at both ends of the arc structure, so that the water vapor sprayed from the concave section 406 is in the shape of a jet. One of the concave sections 406 sprays in the direction of the hinge of the upper baking tray assembly 200 and the lower baking tray assembly 300, and the other concave section 406 sprays in the direction away from the hinge. In this way, the cross-spraying can quickly fill the entire cooking cavity with water vapor, so that the environment where the food is located can quickly reach the required humidity. If the environmental humidity rises slowly during the cooking process, the food will be in a state of slowly heating the food in a low-humidity environment, so that the food is heated in a low-humidity and high-temperature environment, which is not conducive to the food having a good taste. When the environmental humidity can rise quickly during the cooking process, the food is heated in a high-humidity and high-temperature environment, so that the food has a fluffy and tender taste.

[0046] like Figure 2 and Figure 6As shown, if all the water vapor enters the cooking cavity from the concave section 406 and cannot enter the cooking cavity from other places, because the junction of the first side 402 and the second side 403 is small, the area of ​​the concave section 406 will also be small. The water vapor can enter the cooking cavity only through the area of ​​the concave section 406, which cannot meet the requirement of the water vapor entering the cooking cavity quickly. Therefore, it is necessary to allow the water vapor to enter the cooking cavity through the second side 403. Therefore, the second side 403 is provided with an inclined section, and the inclined section includes at least one first inclined section 407 with a gradually rising height, and at least one second inclined section 408 with a gradually falling height. The number of the rising first inclined sections 407 and the number of the descending second inclined sections 408 are arranged as symmetrically as possible, so as to reduce the unfavorable factors such as the slow speed of the water vapor entering the cooking cavity or the inability of the water vapor to be evenly dispersed in the steam groove 301 caused by the turbulence of the water vapor. When multiple first inclined sections 407 and multiple second inclined sections 408 are set, because the size of the steam groove 301 itself is small and the length of the second side 403 is also small, the multiple first inclined sections 407 and the multiple second inclined sections 408 divide the second side 403 into multiple sections. At this time, the lengths of the first inclined sections 407 and the second inclined sections 408 are small, and the numbers of the first inclined sections 407 and the second inclined sections 408 are not equal, so the adverse factors generated are also small and do not affect the speed at which water vapor enters the cooking cavity.

[0047] When more first inclined sections 407 and more second inclined sections 408 are provided, each inclined section will play a role in blocking water vapor from entering the cooking cavity, that is, the more inclined sections are provided, the smaller the passage between the steam groove 301 and the cooking cavity will become, and the amount of water vapor entering the cooking cavity per unit time will be smaller. In order to enable the environment where the food is located to quickly reach the required humidity, that is, to increase the amount of water vapor entering the cooking cavity per unit time, one way is to provide only the first inclined section 407 and the second inclined section 408. The first inclined section 407 is connected to one of the recessed areas and gradually rises to the highest point of the second side 403. After reaching the highest point, the second inclined section 408 is connected to the first inclined section 407 at the highest point. The second inclined section 408 gradually descends from the highest point to connect with another recessed area, so that the second side 403 forms an arch structure, and water vapor enters the cooking cavity from both sides of the arch structure.

[0048] like Figure 7As shown, in order to enable the environment where the food is located to quickly reach the required humidity, that is, to increase the amount of water vapor entering the cooking cavity per unit time, another method is to open a connecting hole 409 on the inclined section, and the connecting hole 409 is used to connect the steam tank 301 and the cooking cavity. The location where the connecting hole 409 is opened is as close as possible to each inclined section. If the location where the connecting hole 409 is opened is far away from the inclined section, it will affect the water storage capacity of the steam tank 301. When the water output is small, the water vapor generated cannot complete the amount of water vapor required for cooking food once. When multiple first inclined sections 407 and multiple second inclined sections 408 are set, because the setting of multiple inclined sections hinders the path of water vapor entering the cooking cavity, in order to increase the amount of water vapor entering the cooking cavity per unit time, the connecting hole 409 is opened on the inclined section to improve the air intake.

[0049] like Figure 3 As shown, when the liquid in the steam tank 301 is heated to generate water vapor, most of the water vapor will enter the cooking cavity from the recessed area or the second side 403. However, if the third side 404 of the steam tank 301 is not tightly fitted with the upper cover 203 of the grilling machine 100, for example, when there is a tolerance between the third side 404 and the upper cover 203, the water vapor will leak from the third side 404 to the external environment, which will not only lose part of the water vapor, but also reduce the pressure in the steam tank 301, so that when in the steam tank 301, the pressure on the water vapor is relatively small, and the water vapor cannot be forced to enter the cooking cavity at a faster speed. Therefore, in order to improve the sealing performance of the steam tank 301, the third side 404 extends upward with a blocking wall 410, and the height of the blocking wall 410 is greater than the height of the first side 402. In order to better fit with the upper cover 203 , a blocking wall 410 is provided on the third side 404 . The blocking wall 410 extending upward can be closer to the upper cover 203 , thereby fitting with the upper cover 203 .

[0050] like Figure 5As shown, when the water vapor from the steam tank 301 directly enters the cooking cavity, the water vapor is basically in a single-point spray state, and it takes a long time to fill the entire cooking cavity with water vapor through the single-point spray state. At the same time, because the hot steam rises upward, as mentioned above, in order to ensure that there is enough water storage in the steam tank 301 to meet the needs of a single cooking, the recessed area and the second side 403 are used to pass the water vapor. The part is located in the relatively upper area of ​​the cooking cavity. If the water vapor directly enters the cooking cavity from this part, the water vapor will first fill the upper area of ​​the cooking cavity. When the upper area of ​​the cooking cavity is filled, the water vapor will continue to fill the lower area of ​​the cooking cavity. The water vapor fills the cooking cavity from top to bottom, so that the hotter water vapor cannot contact the food first, so that the surrounding area of ​​the food reaches a high temperature and high humidity environment, and the time for the water vapor to fill the entire cooking cavity is increased. In order to reduce the time it takes for the water vapor to fill the entire cooking cavity after entering the cooking cavity, the upper baking tray assembly 200 includes an annular rib 201 extending into the grilling area 405, and a gas transmission channel 202 is formed between the annular rib 201 and the second side 403 to guide the steam to enter the cooking cavity from the steam groove 301. The spacing of the gas transmission channels 202 is small, and when the water vapor enters the cooking cavity through the recessed area or the second side 403, the water vapor sprayed at a single point will be evenly distributed in the gas transmission channel 202 after being guided by the gas transmission channel 202, and enter the cooking cavity from the gas transmission channel 202, changing the water vapor from single-point spraying to scattered spraying, so that the water vapor entering the cooking cavity per unit time can cover more area, thereby covering the entire cooking cavity faster. At the same time, the annular rib 201 is arranged close to the lower baking tray of the frying-grilling machine 100, and there is a small gap between the annular rib 201 and the lower baking tray, so that water vapor enters the cooking cavity from a relatively lower position of the cooking cavity. In this way, the hotter water vapor will flow from bottom to top to the upper part of the cooking cavity due to the principle of hot steam rising. The water vapor will first wrap the food and then rise upward. This can ensure that the food is in a high temperature and high humidity environment, and can also reduce the time it takes for the water vapor to fill the entire cooking cavity.

[0051] In order to allow water vapor to smoothly pass through the second side 403 and the gas delivery channel 202 and prevent water vapor from diffusing from the interior of the upper baking tray assembly 200, the drainage cover includes a cover plate 204, which is disposed above the steam groove 301 and spaced apart from the steam groove 301. The spacing between the cover plate 204 and the steam groove 301 allows part of the water vapor to smoothly pass therebetween and enter the cooking cavity.

[0052] like Figure 5As shown, the steam groove 301 can be arranged around the outside of the grilling area 405. Normally, the upper grilling plate assembly 200 of the grilling machine 100 is opened 105° relative to the lower grilling plate assembly 300 to cook food. In order to make the center of gravity of the grilling machine 100 more stable, the upper grilling plate assembly 200 is connected to the lower grilling plate assembly 300 of the grilling machine 100 through a hinge device 500, and the steam groove 301 is arranged on a side close to the hinge device 500. If the steam groove 301 is arranged on a side away from the hinge device 500, the overall center of gravity of the grilling machine 100 is unstable after water is added, so it is easy to tip over.

[0053] The water vapor generated after the liquid in the steam groove 301 is heated is ejected into the cooking cavity. However, due to the limited capacity of the steam groove 301, the water vapor generated can only be ejected to the vicinity of the center line of the grilling area 405, and cannot cross the entire grilling area 405. In order to enable the water vapor to quickly cross the entire grilling area 405, two steam grooves 301 are provided, which are symmetrically distributed on both sides of the hinge device 500. In this way, the steam groove 301 located on the left side of the hinge device 500 is tilted to eject water vapor to the right side of the grilling area 405, and the steam groove 301 located on the right side of the hinge device 500 is tilted to eject water vapor to the left side of the grilling area 405, so that the water vapor can quickly cross the entire grilling area 405, and further quickly fill the entire cooking cavity with water vapor.

[0054] In the present application, the steam groove 301 can be set as one, in which case the steam groove 301 can be set on one side of the hinge device 500, or the steam groove 301 is set on both sides of the hinge device 500 through the oil leakage nozzle but connected as a whole; the steam groove 301 can be set as two, in which case the steam groove 301 can be set on both sides of the hinge device 500.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0056] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
