[0033] Please see Figure 1 and Figure 2 This invention provides a cooking device 1000, which includes a cavity 100, a steam generator 200, and a nozzle 300. The cavity 100 has a cooking chamber 101 and a mounting hole 102, the mounting hole 102 communicating with the cooking chamber 101. The steam generator 200 is used to generate steam. The nozzle 300 is mounted at the mounting hole 102. The nozzle 300 includes a first portion 301 located within the cooking chamber 101, the first portion 301 having at least one vent 303 in the circumferential direction. The nozzle 300 is connected to the steam generator 200 to input the steam generated by the steam generator 200 into the cooking chamber 101 through the vent 303.

[0034] In the cooking device 1000 described above, the first part 301 of the nozzle 300 is provided with at least one air outlet 303 in the circumferential direction, so that the steam generated by the steam generator 200 is sprayed out from the circumferential side of the nozzle 300. Even if there is water vapor mixed with water, it will not be sprayed directly onto the food surface, thereby improving the cooking effect to a certain extent, ensuring that the surface of the food is not wetted or affected by the taste, and enhancing the user's cooking experience.

[0035] Specifically, cooking equipment 1000 can be an appliance used to heat or steam / bake food. Cooking equipment 1000 can include, but is not limited to, steam ovens, steamers, microwave-steam-oven combos, microwave-steam ovens, integrated cooktops, etc.

[0036] Cavity 100 is a closed or semi-closed structural component; optionally, please refer to... Figure 1 The cavity 100 includes a front plate 105, a back plate 104, side plates 106 (left side plate 106 and right side plate 106), a bottom plate 103, and a top plate 107. Optionally, the cavity 100 can be made of metal. A cooking chamber 101 is provided inside the cavity 100, which can hold food ingredients. Steam generated during cooking can be introduced into the cooking chamber 101 from a steam generator 200 to heat the food ingredients.

[0037] A steam generator 200 can be used to generate high-temperature steam and introduce it into the cooking chamber 101 to provide the steam required for heating food. In one embodiment, the steam generator 200 includes a water source interface, a heating element, and a steam outlet. The steam generator 200 can be connected to a water tank 400, which stores water, via the water source interface and a water pump. The steam outlet of the steam generator 200 can be connected to the second part 302 of the nozzle 300 via a pipe. The water in the water tank 400 can be sent to the steam evaporator via the water source interface so that the heating element heats the water to form high-temperature steam. The high-temperature steam can be sent to the nozzle 300 via the steam outlet and pipe to introduce high-temperature steam into the cooking chamber 101.

[0038] The nozzle 300 can be connected to the steam generator 200 and the cooking chamber 101, and is used to guide the steam generated by the steam generator 200 into the cooking chamber 101.

[0039] During the process of steam generation in a steam generator, there may be situations where the steam generator does not reach a sufficiently high temperature or the temperature control accuracy of the steam generator is low, resulting in water droplets being trapped in the steam.

[0040] In related technologies, the nozzle sprays steam directly towards the center of the cooking chamber. Due to inaccurate temperature control of the steam generator, the moisture may not evaporate into steam during the steam output process. The steam mixed with water is sprayed out from the air inlet and drips onto the food surface, affecting the cooking effect and user experience.

[0041] In this embodiment of the invention, the nozzle 300 includes a first portion 301 located within the cooking chamber 101, and the first portion 301 has at least one air outlet 303 in the circumferential direction. The nozzle 300 is connected to a steam generator 200 to input steam generated by the steam generator 200 into the cooking chamber 101 through the air outlet 303.

[0042] Understandably, the first part 301 of the nozzle 300 introduces steam into the cooking chamber 101 through the air outlet 303 located in the circumferential direction of the first part 301, which can cause the steam to be sprayed out from the side of the nozzle 300. Even if the steam is mixed with water, the water will be sprayed out along the perimeter of the cooking chamber 101 and then collected at the bottom of the chamber 100 under the action of gravity, rather than being sprayed onto the food.

[0043] Optionally, the first part 301 may have one or more air vents 303 in the circumferential direction.

[0044] Optionally, the mounting hole 102 can be located at any position on the side plate 106, back plate 104, top plate 107 or front plate 105 of the cavity 100.

[0045] Optionally, the cavity 100 may be provided with multiple mounting holes 102, and correspondingly, the cooking device 1000 may include multiple nozzles 300. The multiple nozzles 300 are installed one-to-one at the multiple mounting holes 102.

[0046] In some implementations, please refer to Figure 1 The cavity 100 includes a base plate 103, and mounting holes 102 are located near the base plate 103.

[0047] In the above embodiment, the mounting hole 102 is set close to the bottom plate 103, so that the nozzle 300 is set close to the bottom plate 103 of the cavity 100. This allows steam to enter the cooking cavity 101 from the position of the cavity 100 close to the bottom plate 103, which helps the steam to diffuse upward evenly and make the steam distribution in the entire cavity 100 more uniform, thereby heating the food evenly.

[0048] Specifically, because steam has a high temperature and low density, it naturally rises. After the steam is introduced into the cooking cavity 101 from the position of the cavity 100 near the bottom plate 103, the steam will be dispersed to various areas of the cavity 100 along the natural rising path, thus forming a more uniform distribution and avoiding the concentration of steam in local areas to a certain extent.

[0049] Optionally, the mounting hole 102 can be located on the back plate 104, front plate 105, or side plate 106 of the cavity 100 near the bottom plate 103.

[0050] Optionally, the mounting hole 102 can be located in the middle or on one side of the back plate 104, front plate 105, or side plate 106 of the cavity 100, and near the bottom plate 103. Figure 1 In this embodiment, the mounting hole 102 is located on one side of the back plate 104 of the cavity 100, and close to the bottom plate 103 and the side plate 106.

[0051] In some implementations, please refer to Figure 1The cavity 100 is provided with a reinforcing rib 108, and the mounting hole 102 is provided on the reinforcing rib 108.

[0052] In the above embodiments, the cavity 100 is provided with reinforcing ribs 108, which can improve the overall strength and deformation resistance of the cavity 100. The mounting hole 102 is provided on the reinforcing ribs 108, which can effectively support the nozzle 300 and, to a certain extent, prevent the cavity 100 from deforming or the nozzle 300 from loosening due to force during use, thus ensuring the durability and stability of the cooking equipment 1000.

[0053] Specifically, stiffener 108 is a structure used to enhance structural strength and rigidity, and can manifest as a protrusion, groove, or other specifically shaped area formed on a thin-walled component. It can be manufactured through processes such as molding, welding, or integral molding.

[0054] The mounting holes 102 on the cavity 100 of the cooking equipment 1000 may deform or even crack due to conditions such as high temperature, high humidity or pressure fluctuations. Therefore, by setting reinforcing ribs 108 and placing the mounting holes 102 on the reinforcing ribs 108, the compressive strength, stability and vibration resistance of the mounting holes 102 can be enhanced to a certain extent, and the effects of thermal expansion and contraction can be reduced.

[0055] Optionally, the shape of the reinforcing rib 108 may include, but is not limited to, triangles, circles, ovals, rectangles, trapezoids, or other regular / irregular shapes.

[0056] Optionally, the reinforcing rib 108 can be disposed at any position on the side plate 106, back plate 104, top plate 107 or front plate 105 of the cavity 100.

[0057] In some implementations, please refer to Figure 1 The reinforcing rib 108 is formed by pressing the cavity 100 toward the cooking cavity 101.

[0058] In the above embodiments, the reinforcing ribs 108 are formed by pressing the cavity 100 toward the cooking cavity 101. Compared with welding or adding other external components, this can reduce manufacturing processes, simplify structural design, reduce costs, and reduce the weight of the cooking equipment 1000 to a certain extent. At the same time, it can effectively utilize the space inside the cavity 100.

[0059] Specifically, forming is a metalworking process that involves placing material (usually a metal sheet) into a mold of a specific shape, and then using mechanical force (such as a press) to shape the material within the mold to obtain the desired shape or structure. This process can be used to manufacture metal parts with various complex shapes, such as reinforcing ribs, grooves, and folds.

[0060] In an embodiment of the present invention, a reinforcing rib 108 is formed by pressing the cavity 100 toward the cooking cavity 101.

[0061] Understandably, pressing the cavity 100 inwards and outwards towards the cooking cavity 101 to form a groove shape to create reinforcing ribs 108 can change the planar shape of the cavity 100, thereby increasing its bending and torsional rigidity to a certain extent. The recessed area can more effectively distribute stress, making the cavity 100 more stable and robust when subjected to external forces.

[0062] Understandably, the forming of reinforcing ribs 108 towards the cooking cavity 101 does not require increasing the volume or thickness of the cavity 100, thus keeping the overall appearance of the cooking device 1000 simple and compact, which is beneficial for use in environments with limited space.

[0063] In some implementations, please refer to Figure 1 The reinforcing rib 108 is triangular and is located on the back plate 104 of the cavity 100. One side of the triangle is connected to the bottom plate 103 of the cavity 100, and the other side is connected to the side plate 106 of the cavity 100.

[0064] In the above embodiment, the triangular reinforcing rib 108 is provided on the back plate 104 of the cavity 100. One side of the triangle is connected to the bottom plate 103 of the cavity 100, and the other side is connected to the side plate 106 of the cavity 100. While utilizing the mechanical properties of the triangle, the force can be effectively and evenly distributed to various parts of the cavity 100, thereby reducing stress concentration in a single part and preventing local deformation of the cavity 100 to a certain extent.

[0065] Specifically, a triangle is a naturally stable structural shape with high resistance to torsion and compression. Triangular reinforcing ribs 108 are provided on the back plate 104, which can effectively improve the deformation resistance of the mounting hole 102 without adding too much material, and prevent the mounting hole 102 from twisting or deforming under high temperature or high pressure conditions.

[0066] One side of the triangular reinforcing rib 108 is connected to the bottom plate 103 of the cavity 100, and the other side is connected to a side plate 106 (e.g., Figure 1 The right side plate shown is connected to form a support frame from the bottom to the side, which can reinforce the back plate 104 and distribute the force evenly to the back plate 104, the bottom plate 103 and the side plate 106, making the whole structure more stable.

[0067] In some implementations, please refer to Figure 2 The diameter of the vent 303 is greater than or equal to 4 mm.

[0068] In the above embodiment, the diameter D of the vent 303 is greater than or equal to 4 mm, which allows more steam to pass through, thereby increasing the steam flow rate and helping to quickly raise the temperature inside the cooking cavity 101 and accelerate the heating process of food.

[0069] Specifically, the orifice diameter of the vent 303 refers to the diameter of the vent 303, that is, the opening size of the orifice. The size of the orifice diameter of the vent 303 determines the speed and flow rate of steam flowing from the nozzle 300 into the cooking chamber 101. A larger orifice diameter can increase the steam flow rate, allowing steam to enter the cooking chamber 101 more quickly, thereby accelerating the rise in temperature inside the cooking chamber 101.

[0070] Optionally, depending on the application scenario, a nozzle 300 with an air outlet 303 of different diameters can be selected.

[0071] In this embodiment of the invention, the diameter D of the vent 303 is set to be greater than or equal to 4 mm, which allows more steam to enter the cooking chamber 101 smoothly and quickly through the vent 303, ensuring a sufficient steam supply in the cooking chamber 101, thereby achieving a more efficient heating effect and a more stable cooking temperature.

[0072] In some examples, the diameter D of the vent 303 is 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, 5 mm, or other values ​​greater than or equal to 4 mm.

[0073] In some implementations, please refer to Figure 2 The wall thickness of the vent 303 is greater than or equal to 0.8 mm.

[0074] In the above embodiments, the wall thickness of the air outlet 303 is greater than or equal to 0.8 mm, which can effectively improve the overall structural strength of the nozzle 300, making it more durable in high temperature and high pressure environments. To a certain extent, it can prevent the nozzle 300 from deforming, cracking or breaking during long-term use or high-pressure steam release, ensuring the long-term stable operation of the cooking equipment 1000.

[0075] Specifically, the wall thickness of the vent 303 refers to the depth of the vent 303. The wall thickness of the vent 303 can affect the durability of the material surrounding the opening of the vent 303, the steam jetting effect, and the corrosion resistance. The thicker the wall thickness, the better the durability of the material surrounding the opening of the vent 303, the better the steam jetting effect, and the better the corrosion resistance. Correspondingly, the better the overall structural strength and durability of the nozzle 300.

[0076] In this embodiment of the invention, the wall thickness of the air outlet 303 is greater than or equal to 0.8 mm, which can improve the structural strength of the material around the opening of the air outlet 303, making it more durable in high temperature and high pressure steam environments, and less prone to deformation or cracking due to long-term use, thereby improving the structural strength and durability of the nozzle 300.

[0077] In some examples, the wall thickness of the vent 303 is 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, or other values ​​greater than or equal to 0.8 mm.

[0078] In some implementations, please refer to Figure 2 The cooking device 1000 includes fasteners (not shown), and the nozzle 300 includes a second part 302 connected to the first part 301. The second part 302 is provided with a fixing part 304. The nozzle 300 is connected to the fasteners through the fixing part 304 to be installed at the mounting hole 102.

[0079] In the above embodiments, the cooperation of fasteners and fixing parts 304 can ensure that the nozzle 300 is firmly installed in the mounting hole 102 to a certain extent, preventing the nozzle 300 from loosening or falling off due to factors such as vibration, pressure or thermal expansion during use, thereby improving the stability of the cooking equipment 1000 and ensuring the normal release of steam and cooking effect.

[0080] Specifically, the first part 301 of the nozzle 300 is located inside the cavity 100 and can serve as an air outlet, while the second part 302 passes through the mounting hole 102 and extends out of the cavity 100, serving as a connecting part. Figure 2 In this embodiment, the second part 302 is provided with a fixing part 304, specifically, the second part 302 is provided with external threads, and the fastener can be a nut with internal threads. The second part 302 can be sequentially provided with a mounting hole 102 and a nut, with the external threads and internal threads engaging until the nut abuts against the outside of the cavity 100, thereby fixing the nozzle 300 at the mounting hole 102.

[0081] Optionally, the fixing part 304 can be a structure with a slot, and correspondingly, the fastener is a snap-fit ​​component that can match the slot. By inserting and locking the snap-fit, the nozzle 300 can be quickly and securely installed at the mounting hole 102.

[0082] In some implementations, please refer to Figure 2 The first part 301 is provided with a limiting part 305, which abuts against the cavity 100 to limit the relative position between the nozzle 300 and the cavity 100.

[0083] In the above embodiments, the limiting part 305 can effectively limit the relative position between the nozzle 300 and the cavity 100 by abutting against the cavity 100, which facilitates the installation of the nozzle 300.

[0084] Specifically, the first part 301 of the nozzle 300 is located inside the cavity 100, and the second part 302 passes through the mounting hole 102 and extends outside the cavity 100. The first part 301 has a protrusion in the circumferential direction to form a limiting part 305. During the process of installing the nozzle 300 at the mounting hole 102, the nozzle 300 can be placed inside the cooking cavity 101, and the second part 302 can be inserted into the mounting hole 102 with the second part facing the mounting hole 102. When the limiting part 305 abuts against the cavity 100, the limiting part 305 restricts the relative position between the nozzle 300 and the cavity 100, that is, the nozzle 300 is installed in place. Then, the nozzle 300 is fixed to the cavity 100 using fasteners, thus completing the installation and fixing of the nozzle 300.

[0085] It can be understood that when the nozzle 300 is subjected to vibration or external force, the limiting part 305 abuts against the inside of the cavity 100, thereby preventing the first part 301 from deviating to the outside of the cavity 100.

[0086] In some implementations, please refer to Figure 2 At least one air outlet 303 includes multiple air outlets 303, which are evenly arranged along the circumferential direction of the first part 301.

[0087] In the above embodiments, the multiple vents 303 are evenly arranged in the circumferential direction, which can ensure the uniform distribution of steam in the cooking chamber 101 to a certain extent, and avoid local overheating or uneven temperature to a certain extent, thereby improving cooking efficiency and the uniformity of food heating.

[0088] Specifically, the first part 301 of the nozzle 300 is provided with multiple air outlets 303, which allows the nozzle 300 to input more steam into the cooking cavity 101. The multiple air outlets 303 are evenly arranged along the circumferential direction of the first part 301, so that the steam can be evenly sprayed out from the side of the nozzle 300, thereby evenly diffusing to the entire cooking cavity 101.

[0089] In some implementations, please refer to Figure 2 The nozzle 300 has a one-piece molded structure.

[0090] In the above embodiments, the nozzle 300 is a one-piece molded structure, which can improve the mechanical strength and stability of the nozzle 300, while simplifying the production process of the nozzle 300, making the manufacturing process simpler, and reducing assembly steps and labor costs.

[0091] Specifically, unibody molding refers to integrating multiple components or structures into a single unit through a manufacturing process, eliminating the need for additional assembly or connection steps during manufacturing. This process is typically achieved through injection molding, die casting, 3D printing, and other methods, resulting in a more compact and robust final product while reducing manufacturing costs and time.

[0092] Alternatively, the nozzle 300 can be made of a metal that is easy to process and has a low cost, such as aluminum alloy.

[0093] Alternatively, the nozzle 300 can be manufactured from plastic using an injection molding process.

[0094] Please see Figure 2 The present invention provides a nozzle 300, which includes a first part 301. The first part 301 is provided with at least one air outlet 303 in the circumferential direction. The nozzle 300 is used to connect to a steam generator 200 to input the steam generated by the steam generator 200 into the cooking chamber 101 of the cooking device 1000 through the air outlet 303.

[0095] In the above embodiment, the first part 301 of the nozzle 300 is provided with at least one air outlet 303 in the circumferential direction, so that the steam generated by the steam generator 200 is sprayed out from the circumferential side of the nozzle 300. Even if there is water vapor mixed with water, it will not be sprayed directly onto the food surface, thereby improving the cooking effect to a certain extent, ensuring that the surface of the food will not be wetted or affect the taste, and enhancing the user's cooking experience.
