Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a cooking appliance. Background Technology

[0002] Steam ovens, ovens, or steam-grill combos can perform corresponding steaming and baking functions.

[0003] Currently, the grilling function is mainly achieved through rotation grilling. Specifically, when grilling food, the food is skewered on a grilling rod, which is placed inside the cooking appliance. A motor drives the grilling rod to rotate. The inside of the cooking appliance is a high-temperature environment. As the grilling rod rotates the food, it is grilled and cooked.

[0004] However, current cooking utensils cause food to lose moisture during baking, which can easily lead to the food becoming dry and hard, resulting in a poor taste. Utility Model Content

[0005] This application provides a cooking appliance to solve the technical problem that in the current cooking appliances, the evaporation of moisture in food during the baking process easily leads to the food becoming dry and hard, resulting in a poor taste.

[0006] This application provides a cooking appliance, which includes:

[0007] Inner pot, the inner pot having a cooking cavity;

[0008] A grilling rod is rotatably disposed in the cooking cavity; the grilling rod has a cavity and is provided with at least one spray hole, the spray hole communicating with the cavity;

[0009] A water supply assembly, wherein the water supply assembly is disposed on the outside of the inner tank;

[0010] The inner liner has a water inlet connector on its side wall, one axial end of the roasting rod is connected to the water inlet connector, and the cavity is connected to the water inlet connector; the water supply assembly is connected to the water inlet connector and supplies water to the cavity through the water inlet connector so that water vapor is sprayed out of the spray hole.

[0011] The cooking appliance provided in this application has a hollow grill rod structure. Water is supplied to the inside of the grill rod by an external water supply component. After the water enters the grill rod, it is heated and the temperature rises. When the water pressure is used to spray the water in the cavity out of the spray hole, the sprayed water mist forms water vapor after contacting the high temperature. The water vapor can moisten the food, prevent the food from being baked too dry and hard, and improve the taste of the food.

[0012] As an optional implementation, the cavity extends along the axial direction of the grill rod; there are multiple spray holes, which are spaced apart along the axial direction of the grill rod; when food is threaded onto the grill rod, at least some of the spray holes are located inside the food.

[0013] With this setup, the high-temperature water vapor sprayed from the misting nozzle can also enter the food, ensuring the food has the right internal humidity and preventing it from becoming too dry.

[0014] As an optional implementation, the end of the water inlet connector facing the roasting rod is provided with a sealing element; the end of the roasting rod that connects with the water inlet connector has a water inlet communicating with the cavity; the sealing element abuts against the roasting rod and is arranged around the water inlet.

[0015] This design improves the sealing of the water inlet connector and prevents leakage when water is introduced into the heating rod.

[0016] As an optional implementation, the water inlet connector has a connecting hole that connects the water supply component and the water inlet.

[0017] The sealing element has a first sealing portion on the side away from the roasting rod, the first sealing portion being at least partially inserted into the connecting hole and abutting against the circumferential inner wall of the connecting hole; the sealing element has a second sealing portion on the side facing the roasting rod, the second sealing portion abutting against the circumferential edge of the water inlet.

[0018] With this configuration, when the water inlet connector is inserted into the end of the heating rod, the sealing element can be compressed, improving the sealing effect.

[0019] As an optional implementation, the end of the water inlet connector facing the inside of the inner tank is provided with a docking groove, the sealing element is disposed in the docking groove, and the end of the heating rod is inserted into the docking groove.

[0020] The mating groove is provided with an elastic element, which abuts against the sealing element and applies a force toward the baking rod to the sealing element so that the sealing element presses the end of the baking rod.

[0021] This design allows the elastic element to provide pre-tightening force to the seal, achieving a movable seal and ensuring that the seal can provide a good seal between the water inlet connector and the end of the heating rod.

[0022] As an optional implementation, the water inlet connector has a first snap-fit ​​portion at one end facing the inside of the inner tank, and the first snap-fit ​​portion is arranged around the circumferential outer edge of the connecting hole; the sealing member has a second snap-fit ​​portion, and the second snap-fit ​​portion snaps into the first snap-fit ​​portion.

[0023] This design helps to limit and fix the installation of the seals, preventing misalignment of the seals and water leakage.

[0024] As an optional implementation, the spray orifice has a first orifice segment, a second orifice segment, a third orifice segment, and the first orifice segment, the second orifice segment, the third orifice segment and the fourth orifice segment are connected sequentially from the inside to the outside of the cavity wall.

[0025] The first orifice has a first flow cross-section, the second orifice has a second flow cross-section, and the third orifice has a third flow cross-section; the first flow cross-section is larger than the second flow cross-section, the second flow cross-section is smaller than the third flow cross-section, and the diameter of the fourth orifice is smaller than the third flow cross-section.

[0026] This setting allows for the compression of the water volume during spraying, creating a certain water pressure.

[0027] As an optional implementation, the diameter of the fourth hole segment is greater than or equal to 0.1 mm and less than or equal to 1 mm.

[0028] With this setting, when water is sprayed from the spray nozzle, it forms a mist, providing more even humidification to the food.

[0029] As an optional implementation, the water supply assembly includes a water tank, a water pump, and a water supply pipeline, wherein the water pump is connected to the water tank.

[0030] The water supply pipeline includes a water distribution connector, a first branch, a first valve, a second branch, and a second valve. The cooking appliance also includes a steam generator. The water distribution connector is connected to the water pump. The first branch connects the water distribution connector and the water inlet connector. The first valve is located on the first branch and controls the on / off state of the first branch. The second branch connects the water distribution connector and the steam generator. The second valve is located on the second branch and controls the on / off state of the second branch. The steam generator is connected to the cooking cavity.

[0031] With this setup, the water supply lines can supply water to the steam generator and the grill rod separately, enabling more cooking functions.

[0032] As an optional implementation, the cooking appliance further includes a drive unit disposed outside the inner pot, and the output end of the drive unit at least partially passes through the cavity wall of the inner pot and enters the cooking cavity; the end of the roasting rod axially away from the water inlet connector is connected to the output end of the drive unit.

[0033] With this setup, the grill rod can rotate the food for baking, and the high-temperature steam sprayed out makes the surface of the food heated and humidified more evenly.

[0034] The cooking appliance provided in this application includes an inner pot, a grill rod, and a water supply assembly. The inner pot has a cooking cavity, and the grill rod is rotatably disposed within the cooking cavity. The grill rod has a cavity and is provided with at least one spray hole, which communicates with the cavity. The water supply assembly is disposed outside the inner pot. A water inlet connector is provided through the side wall of the inner pot, and one axial end of the grill rod is connected to the water inlet connector, with the cavity communicating with the water inlet connector. The water supply assembly is connected to the water inlet connector and supplies water to the cavity through the water inlet connector, so that water vapor is sprayed out from the spray hole. The water vapor can moisten the food upon contact, preventing the food from becoming too dry and hard, and improving the texture of the food.

[0049] Ovens and steam ovens are cooking appliances that can perform a baking function. The inner wall of the appliance is usually equipped with heating elements. During the baking function, the heating elements generate heat radiation and heat convection to create a high-temperature cooking environment. The food to be baked is usually placed on a baking rack inside the appliance. The baking rack is driven by a motor to rotate, so that the food can be heated evenly.

[0050] However, current cooking appliances often cause food to become dry and hard during baking due to moisture evaporation, resulting in a poor texture. Even cooking appliances with steaming functions rely on steam generated by a steam generator. The steam disperses throughout the entire interior space of the appliance, failing to quickly and efficiently humidify the food and control its moisture content, thus making it difficult to guarantee a good texture.

[0051] To address the aforementioned technical problems, this application provides a cooking appliance that uses a hollow grill rod to supply water to the inside of the grill rod via an external water supply component. Water is then sprayed onto the food through spray holes on the grill rod, allowing the food to be quickly moistened. The high-temperature steam generated by the evaporation of the water mist can also assist in heating the food. This not only prevents the food from drying out but also improves cooking efficiency and results, giving the food a better taste.

[0052] Reference Figure 1 and Figure 2 As shown, this application embodiment provides a cooking appliance 10, including an outer shell and an inner pot 100. The inner pot 100 is housed in the outer shell and has a cooking cavity 101. Food is placed in the cooking cavity 101 for cooking.

[0053] In this embodiment, the type of cooking appliance 10 is not limited. For example, the cooking appliance 10 in this embodiment can be an oven, a steam oven, or a steam oven-microwave combination appliance (with microwave function), etc. In this embodiment, a steam oven is mainly used as an example for description.

[0054] A steam oven is an integrated appliance that combines the functions of a steamer and an oven, essentially functioning as multiple independent kitchen appliances. The cooking appliance 10 provided in this application can be either a standalone countertop steam oven or a built-in steam oven, integrated with features such as a gas stove or cabinets, allowing for simultaneous stir-frying / stewing on top and steaming / baking below, freeing up kitchen space. The cooking principle of a steam oven utilizes the appliance's heating system to heat water into steam, which is then used to steam, bake, or cook food. It can also be equipped with heating elements and a fan to heat food through radiation and convection.

[0055] It should be noted that the cooking cavity 101 in this embodiment is formed within the inner pot 100. The inner pot 100 is one of the core components of the steam oven, used to hold and cook food. The material of the inner pot 100 is not limited. For example, the inner pot 100 can be made of stainless steel, which can withstand high temperatures of water and detergents, and also has antibacterial properties and is easy to clean; alternatively, the inner pot 100 can be made of plastic, which has certain impact resistance and electrical insulation properties; or, the inner pot 100 can be made of ceramic, which has the advantages of being smooth, slow-deteriorating, and corrosion-resistant, and can also improve the washing effect. This embodiment does not limit this aspect.

[0056] In the embodiments of this application, reference is made to Figures 1 to 4 As shown, the cooking appliance 10 includes an inner pot 100, a grill rod 200, and a water supply assembly 300. The inner pot 100 has a cooking cavity 101, and the grill rod 200 is rotatably disposed in the cooking cavity 101. The grill rod 200 has a cavity 201 and is provided with at least one spray hole 202, which communicates with the cavity 201. The water supply assembly 300 can supply water into the cavity 201, so that water is sprayed out from the spray hole 202 to moisten the food.

[0057] The water supply component 300 is located outside the inner tank 100. A water inlet connector 110 is provided through the side wall of the inner tank 100. One axial end of the heating rod 200 is connected to the water inlet connector 110, and the cavity 201 is connected to the water inlet connector 110. The water supply component 300 is connected to the water inlet connector 110 and supplies water to the cavity 201 through the water inlet connector 110. The water entering the cavity 201 has a certain water pressure, and the water can be sprayed out from the spray hole 202 to generate water vapor.

[0058] It is understandable that the grill bar 200 has a hollow structure. Water is supplied to the interior of the grill bar 200 through the external water supply component 300. After the water enters the interior of the grill bar 200, it will be heated and the temperature will rise. When the water pressure is used to spray the water in the cavity 201 out of the spray hole 202, the sprayed water mist will form water vapor after contacting the high temperature. The water vapor can moisten the food, prevent the food from being baked too dry and hard, and improve the taste of the food.

[0059] The water vapor can be a mixture of high-temperature steam and water mist. If the temperature of the cooking cavity 101 is high, the sprayed water mist evaporates rapidly, and the resulting water vapor quickly turns into high-temperature steam. Since the water has already been heated by the high-temperature grill rod 200 after entering the cavity 201, it evaporates more easily when sprayed out of the spray hole 202.

[0060] It should be noted that, since the food is skewered on the grill rod 200, the spray holes 202 on the grill rod 200 can be located inside the food, outside the food, or partially inside and partially outside the food. The water vapor sprayed from the spray holes 202 located outside the food can moisten the outer surface of the food; the water vapor sprayed from the spray holes 202 located inside the food can moisten the inside of the food.

[0061] In some embodiments, the cavity 201 extends axially along the grill rod 200. Multiple spray holes 202 are provided, spaced apart axially along the grill rod 200. When food is placed on the grill rod 200, at least some of the spray holes 202 are located inside the food, allowing the high-temperature water vapor emitted from the spray holes 202 to enter the food, ensuring suitable internal humidity and preventing the food from becoming too dry.

[0062] For example, the spray holes 202 can be arranged from one end of the grill rod 200 along its axial direction to the other end, so that water vapor can be sprayed from different positions along the axial direction of the grill rod 200 to humidify the food in the corresponding positions. Furthermore, multiple spray holes 202 arranged along the axial direction of the grill rod 200 can be provided on different surfaces around the grill rod 200, so that water vapor can be sprayed from different directions around the grill rod 200, resulting in a better and more uniform humidification effect.

[0063] The following is a detailed description of the specific connection structure between the heating rod 200 and the water inlet connector 110.

[0064] Please continue to refer to Figures 1 to 4 In one possible implementation, the end of the water inlet connector 110 facing the grill rod 200 is provided with a seal 120, and the end of the grill rod 200 that abuts with the water inlet connector 110 has a water inlet 203 communicating with the cavity 201. The seal 120 abuts against the grill rod 200 and is arranged around the water inlet 203.

[0065] Understandably, the cavity 201 can extend along the axial direction of the grill rod 200, and the water inlet 203 makes one end of the cavity 201 open. The seal 120 is located between the end of the grill rod 200 and the water inlet connector 110, which can improve the sealing performance of the water inlet connector 110 and prevent leakage when water is introduced into the grill rod 200 through the water inlet connector 110.

[0066] For example, the seal 120 can be an annular sealing ring, and the material can be elastic and high temperature resistant silicone, rubber, etc. The embodiments of this application do not specifically limit this.

[0067] In some embodiments, the water inlet connector 110 has a connecting hole 111 that connects the water supply assembly 300 and the water inlet 203. In this way, the water inlet connector 110 can connect the inner side and the outer side of the inner tank 100, so that water from the water supply assembly 300 can enter the cavity 201 of the grill bar 200 through the water inlet connector 110.

[0068] The sealing element 120 has a first sealing portion 121 on the side facing away from the grill rod 200. The first sealing portion 121 is at least partially inserted into the connecting hole 111 and abuts against the circumferential inner wall of the connecting hole 111. The sealing element 120 has a second sealing portion 122 on the side facing the grill rod 200, and the second sealing portion 122 abuts against the circumferential edge of the water inlet 203. When the water inlet connector 110 is inserted into the end of the grill rod 200, the sealing element 120 can be compressed to improve the sealing effect.

[0069] For example, the first sealing part 121 may be a protruding structure on the sealing member 120, the protruding structure is arranged around the periphery of the sealing member 120, and the protruding joint is compressed by interference fit with the inner wall of the connecting hole 111 to ensure good sealing performance.

[0070] For example, the second sealing portion 122 can be an annular protrusion on the sealing member 120 facing the end of the heating rod 200, and its size and contour match the contour of the water inlet 203, so that the periphery of the water outlet can be tightly sealed when the second sealing portion 122 is compressed. For example, along the radial direction of the sealing member 120, in a cross-sectional view of the sealing member 120, the contour of the second sealing portion 122 can be arc-shaped, and the edge of the water inlet 203 of the heating rod 200 can be rounded and chamfered. The arc surfaces of the two are tangentially matched to avoid gaps and have a better sealing effect.

[0071] In some embodiments, the end of the water inlet connector 110 facing the inside of the inner tank 100 is provided with a docking groove 112, the sealing element 120 is disposed in the docking groove 112, and the end of the heating rod 200 is inserted into the docking groove 112.

[0072] The mating groove 112 is equipped with an elastic element 130, which abuts against the sealing element 120 and applies a force toward the baking rod 200 to press the sealing element 120 against the end of the baking rod 200. In this way, the elastic element 130 provides a pre-tightening force to the sealing element 120, achieving a movable seal and ensuring that the sealing element 120 provides a good seal between the water inlet connector 110 and the end of the baking rod 200.

[0073] For example, the elastic element 130 can be a spring. The elastic element 130 is sleeved on the outside of the seal 120, and the seal 120 has a raised edge at one end facing the roasting rod 200. One end of the elastic element 130 abuts against the bottom wall of the mating groove 112. The bottom wall of the mating groove 112 is circumferentially arranged around the outer wall of the connecting hole 111. The other end of the elastic element 130 abuts against the raised edge of the seal 120 at the end facing the roasting rod 200, so that the sealing ring presses against the end of the roasting rod 200.

[0074] In some embodiments, the end of the water inlet connector 110 facing the interior of the inner tank 100 is provided with a first snap-fit ​​portion 113, which surrounds the circumferential outer edge of the connecting hole 111. The sealing member 120 is provided with a second snap-fit ​​portion 123, which snaps into the first snap-fit ​​portion 113. The cooperation of the first snap-fit ​​portion 113 and the second snap-fit ​​portion 123 can limit and fix the installation of the sealing member 120, preventing misalignment of the sealing member 120 and causing water leakage.

[0075] It is understandable that the first snap-fit ​​portion 113 can be a flange around the end of the connecting hole 111 facing the roasting rod 200, and the second snap-fit ​​portion 123 can be a flange around the sealing element 120. The second snap-fit ​​portion 123 is positioned on the side of the first snap-fit ​​portion 113 away from the roasting rod 200 and abuts against the outer wall of the connecting hole 111. In this way, the sealing element 120 can be fixed to the water inlet connector 110 and wrap around the first snap-fit ​​portion 113, resulting in a better sealing effect.

[0076] For example, the seal 120 can slide axially within the mating groove 112, and the elastic force of the elastic member 130 causes the seal 120 to face toward the roasting rod 200 and abut against the end of the roasting rod 200. The elastic member 130 provides pressure to prevent the seal of the seal 120 from being broken when the incoming water has water pressure.

[0077] It should be noted that the sealing element 120 is partially inserted into the connecting hole 111 and pressurized to form the first sealing structure. The first snap-fit ​​part 113 is turned outward relative to the connecting hole 111 to form the second sealing structure. The second snap-fit ​​part 123 is positioned on the back side of the first snap-fit ​​part 113 and the sealing element 120 wraps around the first snap-fit ​​part 113 to form the third sealing structure, which extends the water seepage path and improves the sealing effect.

[0078] In this embodiment, the water inlet connector 110 can be inserted through an opening in the side wall of the inner tank 100, and the water inlet connector 110 can be welded to the inner tank 100 to ensure good sealing. The water inlet connector 110 can be made of metal, such as stainless steel.

[0079] The structure of the spray hole 202 will be described in detail below.

[0080] Please refer to Figures 1 to 5 As an optional implementation, the spray hole 202 has a first hole segment 2021, a second hole segment 2022, a third hole segment 2023 and a fourth hole segment 2024, which are connected sequentially from the inside to the outside of the cavity wall of the cavity 201.

[0081] The first orifice 2021 has a first flow cross section, the second orifice 2022 has a second flow cross section, and the third orifice 2023 has a third flow cross section; the first flow cross section is larger than the second flow cross section, and the second flow cross section is smaller than the third flow cross section; the diameter of the fourth orifice 2024 is smaller than the third flow cross section, and when the spray orifice 202 sprays water, it can compress the amount of water sprayed to form a certain water pressure.

[0082] Understandably, the structure of the spray nozzle 202 compresses the water volume by changing the diameter from a large inflow cross-section to a small cross-section. At this time, the water output is based on the water volume of the second flow cross-section after the inflow. As the third flow cross-section increases, the water volume is squeezed into the final fourth flow cross-section and sprayed out of the grill rod 200. This is because the water ejection is under water pressure.

[0083] In some embodiments, the diameter of the fourth orifice 2024 is greater than or equal to 0.1 mm and less than or equal to 1 mm. When water enters the third flow section, the orifice diameter entering the fourth flow section is maintained at 0.1~1 mm, so that the water is sprayed out of the grill rod 200.

[0084] For example, the transition from the third flow section to the fourth flow section is conical, and the fourth orifice 2024 has a circular orifice structure, so that the fourth flow section sprays out a conical spray, which more evenly humidifies the food.

[0085] For example, the diameter of the fourth orifice 2024 can be 0.1mm, 0.11mm, 0.2mm, 0.3mm, 0.5mm, 0.9mm, 0.91mm, 1mm, etc. For instance, the actual diameter of the fourth orifice 2024 can be between 0.1mm and 0.3mm to ensure that the sprayed water mist has a certain water pressure to form a larger area of ​​water vapor spray, resulting in a better humidification effect.

[0086] In some embodiments, the water supply assembly 300 includes a water tank, a water pump, and a water supply pipeline 310, with the water pump connected to the water tank.

[0087] The water supply pipeline 310 includes a water distribution connector 320, a first branch 311, a first valve 312, a second branch 313, and a second valve 314. The cooking appliance 10 also includes a steam generator 400. The water distribution connector 320 is connected to a water pump. The first branch 311 connects the water distribution connector 320 and the water inlet connector 110. The first valve 312 is located on the first branch 311 and controls the opening and closing of the first branch 311. The second branch 313 connects the water distribution connector 320 and the steam generator 400. The second valve 314 is located on the second branch 313 and controls the opening and closing of the second branch 313. The steam generator 400 is connected to the cooking cavity 101.

[0088] Understandably, the water supply pipe 310 can supply water to the steam generator 400 and the grill rod 200 respectively, and the high-temperature steam generated by the steam generator 400 can enter the cooking cavity 101. The first branch 311 can be used to supply water to the grill rod 200, and the second branch 313 can be used to supply high-temperature steam to the cooking cavity 101, thus enabling more cooking functions.

[0089] For example, during the cooking process, water can be supplied to one of the first branch 311 and the second branch 313, or water can be supplied to both the first branch 311 and the second branch 313 at the same time. The specific choice can be made according to the type of food being cooked and the cooking method. This application embodiment does not make specific limitations in this regard.

[0090] In some embodiments, the cooking appliance 10 may further include a drive unit 500 disposed outside the inner pot 100, and the output end of the drive unit 500 at least partially passes through the cavity wall of the inner pot 100 and enters the cooking cavity 101. The end of the grill rod 200 axially away from the water inlet connector 110 is connected to the output end of the drive unit 500.

[0091] It is understandable that the drive unit 500 and the water inlet connector 110 are respectively arranged on both sides of the inner tank 100, and the roasting rod 200 is horizontally placed in the inner tank 100. The drive unit 500 and the water inlet connector 110 can respectively cooperate with the two ends of the roasting rod 200 in the axial direction.

[0092] For example, the drive unit 500 can be a motor, which drives the grill rod 200 to rotate. The grill rod 200 can rotate the food to bake it. With the high temperature water vapor sprayed out, the surface of the food can be heated and humidified more evenly.

[0093] It should be noted that a shelf can be installed on the inner wall of the inner liner 100, and the two ends of the roasting rod 200 can be supported on the shelf to avoid the water inlet connector 110 and the motor output shaft bearing the weight directly, so as to ensure the stability and reliability of the support structure of the roasting rod 200.

[0094] The cooking appliance provided in this application includes an inner pot, a grill rod, and a water supply assembly.
