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 rotating grilling. Specifically, when grilling food, the food is skewered on a grilling rod, which is placed inside the cooking appliance. During the grilling process, the inside of the cooking appliance is a high-temperature environment. In order to ensure that the surface of the food is heated evenly, a motor is used to drive the grilling rod to rotate, which in turn drives the food to rotate, thus achieving the grilling and cooking of the food.

[0004] However, during the roasting process, in order to make the roasting rod rotate with the food, it is necessary to use a roasting fork on the roasting rod or to fix the food in place by tying it up, which makes it inconvenient to take the food out and put it in. Utility Model Content

[0005] This application provides a cooking appliance to solve the technical problem that current cooking appliances require the use of a roasting fork on a roasting rod or the use of binding to fix the food when roasting, which makes it inconvenient to handle food.

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

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

[0008] A grilling rod is disposed in the cooking cavity; the grilling rod has a cavity; a first air inlet communicating with the cavity is provided at the first axial end of the grilling rod;

[0009] An airflow generating component, the airflow generating component being configured to introduce airflow from the first air inlet into the cavity;

[0010] The grill rod has an air intake on its side wall near its first axial end and an air outlet on its side wall near its second axial end. Airflow into the cavity flows from the first end to the second end of the grill rod, so that the air intake creates a negative pressure to draw in airflow. Airflow is blown out from the first air outlet and flows toward the first end of the grill rod, so that the hot air in the cooking cavity forms convection and wraps around the food skewered on the grill rod.

[0011] The cooking appliance provided in this application designs the grill rod as a hollow structure, and uses an external airflow generating component to blow air into the grill rod. This creates a negative pressure at one end of the grill rod, drawing air into the cooking cavity. The airflow entering the grill rod can flow out from the other end of the grill rod into the cooking cavity, forming an airflow circulation. This allows the heat flow in the cooking cavity to coat the food on the grill rod, achieving a uniform heating effect for the food without rotating the grill rod.

[0012] As an optional implementation, the grill rod includes a grill rod body and a telescopic tube, the grill rod body being used to form the cavity; the cavity has an opening at a first end in the axial direction of the grill rod body, and the telescopic tube is movably inserted into the opening.

[0013] The telescopic tube is used to form the first air inlet, which extends axially along the telescopic tube.

[0014] This design facilitates the assembly of the grill rod inside the inner pot.

[0015] As an optional implementation, there are multiple air intakes, which are spaced apart on the circumferential sidewall of the first end of the roasting rod body.

[0016] This design improves the efficiency of drawing airflow from the cooking cavity into the cavity using jet propulsion.

[0017] As an optional implementation, the plurality of air inlets form an air suction area at the first end of the roasting rod body, the air suction area extending along the axial direction of the roasting rod body; the telescopic tube is inserted into the cavity to a depth greater than the length of the air suction area.

[0018] This design creates a negative pressure zone between the outer wall of the telescopic tube and the inner wall of the heating rod body, improving the efficiency of hot airflow intake from the air intake hole.

[0019] As an optional implementation, the inner wall of the first axial end of the roasting rod body is provided with a limiting groove, and the outer wall of the telescopic tube has a protruding limiting part, which cooperates with the limiting groove; when the telescopic tube moves relative to the roasting rod body along its axial direction, the limiting part slides in the limiting groove.

[0020] This design guides the movement of the telescopic tube, improving its smoothness.

[0021] As an optional implementation, an elastic element is provided in the limiting groove, one end of the elastic element abuts against the end wall of the limiting groove, and the other end of the elastic element abuts against the limiting part; the elastic element is configured to apply a force toward the outside of the opening to the telescopic tube.

[0022] This design provides pre-tension to the telescopic tube, ensuring the stability of the grill rod within the inner liner.

[0023] As an optional implementation, the inner liner is provided with an air inlet connector on its side wall, the air inlet connector penetrating the side wall of the inner liner; the end of the air inlet connector facing the outside of the inner liner is connected to the airflow generating component; the end of the air inlet connector facing the inside of the inner liner is connected to the telescopic tube.

[0024] The air inlet connector has an annular sealing part at one end facing the inside of the inner liner, and the annular sealing part abuts against the inner wall of the inner liner.

[0025] This design ensures a good seal between the steam inlet connector and the inner liner.

[0026] As an optional implementation, the airflow generating assembly includes an air inlet housing and a fan; the air inlet housing is connected to the outer side wall of the inner liner; the air inlet housing has an air intake channel, and the side wall of the inner liner is provided with an air outlet, which communicates with the air intake channel.

[0027] The fan has a second air inlet and a second air outlet. The first air inlet is connected to the air intake channel, and the second air outlet is connected to the air inlet connector.

[0028] This setup allows for efficient airflow circulation.

[0029] As an optional implementation, the air outlet and the air inlet are located on the same side wall of the inner liner.

[0030] With this configuration, the hot air flowing back to the airflow generating component in the cooking cavity can flow from one end of the grill rod to the other, thereby heating the surface of the food.

[0031] As an optional implementation, the air inlet housing is arranged around the air inlet connector to form an annular air intake channel; there are multiple air outlets, and a number of the air outlets are arranged around the air inlet connector and opposite to the air intake channel.

[0032] With this configuration, the hot airflow returning to the airflow generating component in the cooking cavity can more easily envelop the food, resulting in a better heating effect.

[0033] The cooking appliance provided in this application includes an inner pot, a grill rod, and an airflow generating assembly. The inner pot has a cooking cavity, and the grill rod is disposed within the cooking cavity. The grill rod has a cavity. A first air inlet communicating with the cavity is provided at the first axial end of the grill rod, and the airflow generating assembly is configured to introduce airflow into the cavity from the first air inlet. An air suction port is provided on the side wall near its first axial end of the grill rod, and a first air outlet is provided on the side wall near its second axial end of the grill rod. The airflow entering the cavity flows from the first end to the second end of the grill rod. The air suction port forms a negative pressure to draw in airflow, and the first air outlet blows out airflow, so that the hot air in the cooking cavity forms convection and wraps around the food pierced on the grill rod, achieving the effect of uniform heating of the food without rotating the grill rod.

[0047] 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.

[0048] However, currently, when cooking food, the grill rod needs to rotate the food, so a fork is used to fix the food on the grill rod or to tie it up. This makes it time-consuming and laborious to fix the food on the fork before cooking begins, and it is also inconvenient to remove the food after it is cooked, and there is a risk of being burned by the food.

[0049] In addition, during the baking process, as the food cooks, the fixing of the grill rod to the food may loosen, causing the food to be unable to rotate with the grill rod. As a result, the side of the food facing the heating tube is prone to burning, while the other sides may remain uncooked, leading to uneven heating and poor cooking results.

[0050] To address the aforementioned technical problems, this application provides a cooking appliance in which the grill rod is designed as a hollow structure, allowing external airflow to be blown into the interior of the grill rod. The jetting action creates negative pressure within the grill rod, drawing in hot airflow from the cooking cavity. This hot airflow, after exiting the grill rod into the cooking cavity, forms thermal convection. The high-temperature airflow envelops the food during its flow, ensuring even heating of the food surface. Thus, food can be grilled without rotating the grill rod, providing excellent cooking results while making food handling more convenient.

[0051] Reference Figure 1 and Figure 2As 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In the embodiments of this application, reference is made to Figures 1 to 6 As shown, the cooking appliance 10 includes an inner pot 100, a grill rod 200, and an airflow generating assembly 300. The inner pot 100 has a cooking cavity 101, and the grill rod 200 is disposed in the cooking cavity 101. When cooking food, the grill rod 200 is mounted inside the cooking cavity 101, and food can be placed on the grill rod 200, which provides support for the food.

[0056] The grill rod 200 has a cavity 201, and a first air inlet 202 communicating with the cavity 201 is provided at the first axial end of the grill rod 200. The airflow generating assembly 300 is configured to introduce airflow into the cavity 201 from the first air inlet 202. The airflow generating assembly 300 can be disposed outside the inner liner 100.

[0057] In some embodiments, the side wall of the roasting rod 200 near its first axial end is provided with an air intake, and the side wall of the roasting rod 200 near its second axial end is provided with a first air outlet 203.

[0058] It is understood that the airflow entering the cavity 201 flows from the first end to the second end of the grill rod 200, the air inlet forms a negative pressure to draw in the airflow, and the first air outlet 203 blows out the airflow, so that the hot air in the cooking cavity 101 forms convection and wraps around the food placed on top.

[0059] Since the air intake is located near the first end of the grill rod 200, and the first air outlet 203 is located near the second end of the grill rod 200, when the airflow entering the cooking cavity 101 flows from the first air outlet 203 to the air intake, the direction of the hot airflow is approximately from the second end of the grill rod 200 to the first end of the grill rod 200. The hot airflow can better and more efficiently contact the food surface in the axial direction of the grill rod 200, resulting in a better and more uniform heating effect on the food.

[0060] It should be noted that in the cooking appliance 10 provided in this application, the grill rod 200 has a hollow structure. The external airflow generating component 300 blows air into the grill rod 200, forming a negative pressure at one end of the grill rod 200 to draw air into the cooking cavity 101. The airflow entering the grill rod 200 can flow out from the other end of the grill rod 200 into the cooking cavity 101, forming an airflow circulation. This allows the heat flow in the cooking cavity 101 to wrap around the food on the grill rod 200, achieving a uniform heating effect on the food without rotating the grill rod 200.

[0061] In one possible implementation, the grill rod 200 can be horizontally positioned within the cooking cavity 101. For example, the airflow generating assembly 300 is located on the left side of the inner liner 100, and the first air inlet 202 of the grill rod 200 is located at the left end. After the airflow enters the cavity 201, it flows from left to right and exits from the first air outlet 203 at the right end of the grill rod 200.

[0062] Understandably, since the grill rod 200 has a rod-shaped structure and passes through the interior of the food being grilled, and the food is relatively large, such as roasted chicken, roasted duck, roasted fish, etc., when the airflow enters the cooking cavity 101 from the first air outlet 203, under the suction of the air intake 211, the hot airflow in the cooking cavity 101 flows from right to left, and during this process, the hot airflow can wrap around the food pierced on the grill rod 200.

[0063] In another possible implementation, the grill rod 200 can be vertically arranged in the cooking cavity 101, and the food to be grilled can be skewered and hung on the grill rod 200. The airflow generating component 300 can be arranged on the outer side of the top of the inner pot 100 or the outer side of the bottom of the inner pot 100. Accordingly, the airflow flows from bottom to top or from top to bottom in the cooking cavity 101, wrapping around the food and heating it evenly.

[0064] The specific structure of the grill bar 200 will be described in detail below.

[0065] Please refer to Figures 1 to 6 In one possible implementation, the grill rod 200 may include a grill rod body 210 and a telescopic tube 220. The grill rod body 210 forms a cavity 201. The cavity 201 has an opening at a first end in the axial direction of the grill rod body 210, and the telescopic tube 220 is movably inserted into the opening. The telescopic tube 220 forms a first air inlet 202, which extends axially along the telescopic tube 220, thereby facilitating the assembly of the grill rod 200 inside the inner liner 100.

[0066] Understandably, when it is necessary to assemble or disassemble the grill rod 200, the telescopic tube 220 can be retracted into the grill rod body 210, thus shortening the overall length of the grill rod 200 and facilitating its assembly inside the inner liner 100. When the grill rod 200 is installed in the inner liner 100, the telescopic tube 220 extends from the end of the grill rod body 210, and the overall length of the grill rod 200 is extended, allowing both ends of the grill rod 200 to be stably supported on both sides of the inner liner 100.

[0067] In some embodiments, there are multiple air intakes, which are spaced apart on the circumferential sidewall of the first end of the grill rod body 210, thereby improving the efficiency of drawing airflow from the cooking cavity 101 into the cavity 201 by means of jet action.

[0068] Understandably, multiple air intakes form an air intake zone at the first end of the grill rod body 210, extending axially along the grill rod body 210; the depth to which the telescopic tube 220 is inserted into the cavity 201 is greater than the length of the air intake zone. In the radial projection of the grill rod 200, there is an overlapping area between the air intake 211 and the telescopic tube 220, which can create a region prone to negative pressure between the outer wall of the telescopic tube 220 and the inner wall of the grill rod body 210, improving the efficiency of hot airflow intake from the air intake 211.

[0069] It is understandable that there is a gap between the outer wall of the telescopic tube 220 and the inner wall of the grill rod body 210, which can form a narrower suction area between the outer wall of the telescopic tube 220 and the inner wall of the grill rod body 210, making it easier to form negative pressure and draw air from the cooking cavity 101 into the cavity 201 through the suction hole 211, thereby improving the efficiency of hot airflow intake from the suction hole 211.

[0070] In some embodiments, the inner wall of the first axial end of the grill rod body 210 is provided with a limiting groove, and the outer wall of the telescopic tube 220 has a protruding limiting part that cooperates with the limiting groove. When the telescopic tube 220 moves axially relative to the grill rod body 210, the limiting part slides in the limiting groove, thereby guiding the movement of the telescopic tube 220 and improving the smoothness of its movement.

[0071] For example, an elastic element 230 is provided in the limiting groove, one end of the elastic element 230 abuts against the end wall of the limiting groove, and the other end of the elastic element 230 abuts against the limiting portion. The elastic element 230 is configured to apply a force toward the outside of the opening to the telescopic tube 220.

[0072] For example, the elastic element 230 can be a spring, which can provide preload to the telescopic tube 220 to ensure the stability of the grill rod 200 within the inner liner 100.

[0073] In some embodiments, the inner liner 100 has an air inlet connector 110 on its side wall. The air inlet connector 110 penetrates the side wall of the inner liner 100. One end of the air inlet connector 110 facing the outside of the inner liner 100 is connected to the airflow generating component 300, and the other end of the air inlet connector 110 facing the inside of the inner liner 100 is connected to the telescopic tube 220.

[0074] The air inlet connector 110 has an annular sealing part 111 at one end facing the inside of the inner liner 100. The annular sealing part 111 abuts against the inner wall of the inner liner 100, thereby ensuring good sealing between the air inlet connector and the inner liner 100.

[0075] In some embodiments, the airflow generating assembly 300 may include an air inlet housing 310 and a fan 320. The air inlet housing 310 is connected to the outer side wall of the inner liner 100. The air inlet housing 310 has an air intake channel 311, and the side wall of the inner liner 100 is provided with an air outlet 102, which communicates with the air intake channel 311.

[0076] The fan 320 has a second air inlet 321 and a second air outlet 322. The first air inlet 202 is connected to the air intake channel 311, and the second air outlet 322 is connected to the air inlet connector 110, thereby achieving efficient airflow circulation.

[0077] It is understandable that the airflow generating component 300 can introduce airflow into the cavity 201. After the airflow enters the cavity 201 from the first air inlet 202, it flows from the first end of the grill rod 200 to the second end in the cavity 201. After the airflow in the cavity 201 flows out from the first air outlet 203, it will enter the cooking cavity 101. The airflow generating component 300 will draw the airflow out of the cooking cavity 101. Therefore, the airflow flowing out from the first air outlet 203 will flow towards the air outlet 102. In this way, the hot air in the cooking cavity 101 can form convection and wrap around the food skewered on the grill rod 200.

[0078] For example, the air outlet 102 and the air inlet connector 110 are located on the same side wall of the inner cavity 100, and the hot air flowing back to the airflow generating assembly 300 in the cooking cavity 101 can flow from one end of the grill rod 200 to the other end, thereby heating the surface of the food.

[0079] For example, the air inlet housing 310 is arranged around the air inlet connector 110 to form an annular air intake channel 311. Multiple air outlets 102 are arranged around the air inlet connector 110 and opposite the air intake channel 311. It can be understood that when the air outlets 102 are positioned close to the air inlet connector 110, they can be close to the first end of the grill rod 200, i.e., the location where the airflow in the cooking cavity 101 returns to the airflow generating component 300 is close to the first end of the grill rod 200. Meanwhile, the air outlet of the first air outlet 203 is close to the second end of the grill rod 200. Thus, when the airflow flows from the first air outlet 203 to the air outlet 102, the resulting hot airflow can flow along the contour surface of the food that protrudes relative to the grill rod 200, providing a better coating effect on the food.

[0080] For example, the air outlet 102 can be a round hole, a square hole, an elliptical hole, or other polygonal holes. Multiple air outlets 102 can be arranged in a circumferential array. This application embodiment does not specifically limit the number, shape, or arrangement of the air outlets 102.

[0081] For example, the fan 320 includes a fan housing 323, a motor 324, and a fan blade 325. The motor 324 is connected to the top of the fan housing 323, and the fan blade 325 is located inside the fan housing 323 and connected to the output shaft of the motor 324. A second air inlet 321 is disposed in the fan housing 323 and located on the suction side of the fan blade 325; a second air outlet 322 is disposed in the fan housing 323 and located on the blowing side of the fan blade 325. In this way, the space occupied by the airflow generating assembly 300 outside the inner liner 100 can be reduced, and the overall volume of the cooking cavity can be reduced.

[0082] Please refer to Figures 1 to 6 In some embodiments, the first air outlet 203 includes multiple through holes arranged in a circumferential array on the side wall of the second end of the grill rod 200.

[0083] Understandably, the airflow inside the cavity 201 can be discharged simultaneously from multiple through holes around the grill rod 200, and the airflow flowing out from inside the grill rod 200 can flow back to the other end of the grill rod 200 from all directions, so that the hot airflow can more evenly coat the outer surface of the food, and the food has a more uniform heating effect.

[0084] The airflow entering the cavity 201 from the first air inlet 202 at the first end of the grill rod 200 will pass through the location of the suction hole 211. Therefore, the hot airflow flowing over the food surface can be partially drawn back into the cavity 201 of the grill rod 200 using jet action. When the airflow flows through the area where the suction hole 211 is located, the air pressure in the cavity 201 at the location of the suction hole 211 is lower than the air pressure in the cooking cavity 101. The hot airflow in the cooking cavity 101 is drawn into the cavity 201. In this way, the hot airflow wrapping the food flowing from the second end to the first end of the grill rod 200 will not only enter the airflow generating component 300, but will also partially enter the cavity 201 through the suction hole 211. This allows the hot airflow to converge towards the first end of the grill rod 200 along the contour of the food, resulting in a more comprehensive and uniform heating effect on the food.

[0085] It should be noted that in the above structure, when the airflow generating component 300 is activated, two airflow circulation paths can be formed. First, airflow is blown into the cavity 201 through the airflow generating component 300, flows along the cavity 201 from the first end of the grill rod 200 to the second end, exits from the first air outlet 203, flows into the cooking cavity 101 towards the air outlet 102, and then flows back to the airflow generating component 300 to form a circulation. Second, hot air in the cooking cavity 101 is drawn into the cavity 201 from the air intake at the first end of the grill rod 200 due to jet action, flows along the cavity 201 from the first end of the grill rod 200 to the second end, exits from the first air outlet 203, and then flows back into the cooking cavity 101 towards the first end of the grill rod 200 to form a circulation. The two airflow circulation paths overlap.

[0086] In some embodiments, the inner liner 100 has a support member 120 on the side of the cavity wall away from the air inlet 110. The support member 120 has a positioning groove 121 facing the inside of the cooking cavity 101. The second end of the grill rod 200 is inserted into the positioning groove 121 in the axial direction, thereby ensuring that the end of the grill rod 200 has good support stability and reliability when it is placed in the inner liner 100.

[0087] The cooking appliance provided in this application includes an inner pot, a grill rod, and an airflow generating assembly. The inner pot has a cooking cavity, and the grill rod is disposed within the cooking cavity. The grill rod has a cavity. A first air inlet communicating with the cavity is provided at the first axial end of the grill rod, and the airflow generating assembly is configured to introduce airflow into the cavity from the first air inlet. An air suction port is provided on the side wall near its first axial end of the grill rod, and a first air outlet is provided on the side wall near its second axial end of the grill rod. The airflow entering the cavity flows from the first end to the second end of the grill rod. The air suction port forms a negative pressure to draw in airflow, and the first air outlet blows out airflow, so that the hot air in the cooking cavity forms convection and wraps around the food pierced on the grill rod, achieving the effect of uniform heating of the food without rotating the grill rod.

[0088] It should be noted that, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0089] In the description of the embodiments of this application, the term "and / or" merely indicates a relationship describing the associated objects, meaning that three relationships can exist.
