Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The following is for reference. Figures 1-8 The cooking device 100 according to an embodiment of the present invention has a short steam channel 212, which allows the generated steam to quickly enter the cooking chamber 11 for cooking food. During the flow of steam in the steam channel 212, the steam can be reheated by the heat in the heating chamber 213, reducing the generation of condensate. Thus, the steam can be continuously discharged, avoiding the situation where condensate soaks the food.

[0038] like Figures 1-5 and Figure 8 As shown, the cooking device 100 according to an embodiment of the present invention includes: a main unit 1 and a steam component 2.

[0039] The main unit 1 is the core component of the cooking device 100, providing heat for cooking food. A cooking cavity 11 is formed within the main unit 1, meaning food can be placed inside the cooking cavity 11 and heated by the main unit 1 to complete the cooking process. The steam component 2 generates steam, which is then delivered to the surface of the food during cooking to retain moisture, improve texture, and expand the range of cooking methods.

[0040] The steam assembly 2 includes a steam shell 21 and a first heating element 22. The steam shell 21 has a water inlet 211, a steam channel 212 and a heating chamber 213. The first heating element 22 is used to heat the heating chamber 213.

[0041] The inlet 211 is used to connect to an external water source so that the external water source can supply water into the steam shell 21 through the inlet 211, so that the external liquid water enters the steam shell 21. After entering the steam shell 21, the liquid water is transported to the heating chamber 213. The liquid water is heated in the heating chamber 213 by the first heating element 22. The first heating element 22 can convert electrical energy into heat energy, thereby providing enough heat to make the liquid water in the heating chamber 213 evaporate and form steam. The steam can enter the steam channel 212 and be quickly discharged.

[0042] Furthermore, the steam channel 212 is provided with a steam inlet 2121 communicating with the heating chamber 213 and a steam outlet 2122 communicating with the cooking chamber 11. For example, one end of the steam channel 212 is configured as the steam inlet 2121 and the other end as the steam outlet 2122. Steam generated in the heating chamber 213 can enter the steam channel 212 through the steam inlet 2121, and steam in the steam channel 212 can flow into the cooking chamber 11 through the steam outlet 2122. In other words, as the amount of steam generated in the heating chamber 213 increases, the steam can enter the steam channel 212 through the steam inlet 2121 under gradually increasing pressure, and then exit into the cooking chamber 11 through the steam outlet 2122. Thus, the steam assembly 2 generates steam and delivers it to the surface of the food, maintaining the texture of the food, solving the problem of dry food, and improving the user experience.

[0043] The steam shell 21 includes a partition wall 214. A steam channel 212 and a heating chamber 213 are located on opposite sides of the partition wall 214. A steam inlet 2121 is located at the top of the steam channel 212 and communicates with the top of the heating chamber 213. In other words, a partition wall 214 can be installed inside the steam shell 21, positioned between the steam channel 212 and the heating chamber 213. The top of the partition wall 214 has a steam inlet 2121, allowing steam to be transported from the heating chamber 213 to the steam channel 212 via the steam inlet 2121. The steam inlet 2121 is located at the top of the partition wall 214, meaning the top of the steam channel 212 communicates with the top of the heating chamber 213. This allows the generated steam to quickly reach the steam inlet 2121 when it accumulates at the top of the steam shell 21, increasing the steam discharge rate.

[0044] In actual use, liquid water enters the heating chamber 213 through the inlet 211. The first heating element 22 heats the water in the heating chamber 213 to form steam. The steam then gathers at the top of the heating chamber 213, passes through the steam inlet 2121, bypasses the top of the partition wall 214, and enters the steam channel 212. It then enters the cooking chamber 11 through the steam outlet 2122 and is delivered to the food surface, preventing the food from drying out. As the steam flows through the steam channel 212, the heat in the heating chamber 213 can enter the steam channel 212 from the partition wall 214, thus heating the steam in the steam channel 212. This prevents the steam from condensing into water during its flow through the steam channel 212, preventing excessive condensate from entering the cooking chamber 11 and soaking the food, thus maintaining the food's texture.

[0045] According to the cooking device 100 of this utility model embodiment, the steam channel 212 and the heating chamber 213 share a partition wall 214, and the steam inlet 2121 connects the steam channel 212 and the cooking chamber 11 at the top, thereby effectively shortening the length of the steam channel 212 and accelerating the speed at which steam is discharged from the heating chamber 213. At the same time, the heating chamber 213 can heat the partition wall 214, reducing the generation of condensate when steam passes through the steam channel 212, so that steam can be continuously discharged, ensuring the cooking effect on food.

[0046] In some embodiments, the height of the steam inlet 2121 is higher than the height of the water inlet 211. That is, the steam inlet 2121 can be located above the water inlet 211, such as by placing the steam inlet 2121 above the water inlet 211 on the same side, or by placing the steam inlet 2121 above the water inlet 211 on a different side.

[0047] Therefore, when water is supplied into the heating chamber 213 through the water inlet 211, the water entering the heating chamber 213 will not directly enter the steam inlet 2121, or the water splashed in the heating chamber 213 during the water supply process will not easily flow towards the steam inlet 2121, reducing the risk of liquid water entering the cooking chamber 11. At the same time, the steam inlet 2121 is set higher and the water inlet 211 is set lower, which allows the liquid water at the steam inlet 2121 and below it to flow smoothly back to the bottom of the heating chamber 213, and the steam at the steam inlet 2121 will not enter the water inlet 211. Especially when the amount of liquid water in the heating chamber 213 is small, the steam will not flow too low towards the water inlet 211, ensuring smooth water intake and stable steam flow towards the steam inlet 2121, improving the rationality of the structural design and ensuring the reliability of steam generation.

[0048] And / or, in some other embodiments, the steam outlet 2122 is located at the bottom of the steam channel 212. It should be noted that, in actual installation, the steam assembly 2 is located at the top of the main unit 1, that is, the steam assembly 2 is located at the top of the cooking chamber 11. Therefore, placing the steam outlet 2122 at the bottom of the steam channel 212 facilitates communication between the steam channel 212 and the cooking chamber 11, allowing steam at the steam outlet 2122 to directly enter the cooking chamber 11 from the top, reducing the length of the steam channel 212, increasing the steam discharge speed, and thus reducing the generation of condensate.

[0049] In some embodiments, the cooking device 100 also includes a water tank 3. That is, the cooking device 100 can store water in the water tank 3 to maintain a continuous water supply to the steam component 2, thereby ensuring that the steam component 2 can continuously generate steam. Thus, water can be supplied to the heating chamber 213 through the built-in water tank 3 of the cooking device 100, eliminating the need for a separate external water source. This makes it more convenient to use, reduces the dependence of the cooking device 100 on the location of an external water source, and allows the cooking device 100 to be used in different spaces, increasing its applicability.

[0050] Furthermore, the water tank 3 is equipped with a water outlet 31, which is connected to the water inlet 211 via a connecting water pipe 5. In other words, the water tank 3 and the steam assembly 2 are connected via the connecting water pipe 5, allowing water in the water tank 3 to be transported to the steam assembly 2 via the connecting water pipe 5, thereby generating steam. At least a portion of the connecting water pipe 5 is lower than the water inlet 211; that is, the connecting water pipe 5 can be constructed as a downwardly convex U-shaped structure. This way, when the water tank 3 can no longer supply water to the steam assembly 2, some water will remain inside the connecting water pipe 5, forming a water seal. This prevents external air from entering the heating chamber 213 through the connecting water pipe 5, and also prevents steam generated in the heating chamber 213 from flowing out through the connecting water pipe 5.

[0051] Specifically, such as Figures 5-7 As shown, the outlet 31 and inlet 211 are connected by a U-shaped connecting water pipe 5. The middle of the connecting water pipe 5 protrudes downwards. When the water tank 3 supplies water to the steam assembly 2, the water in the water tank 3 flows from the outlet 31 into the connecting water pipe 5, and then from the inlet 211 into the steam assembly 2. Thus, through the interconnection between the steam assembly 2, the water tank 3, and the connecting water pipe 5, steam is generated. When the water level in the water tank 3 is insufficient or the water supply to the steam assembly 2 stops, some of the water flowing into the steam assembly 2 will continue to be evaporated by the steam assembly 2 to form steam, while the other part of the water will remain in the connecting water pipe 5, neither flowing into the steam assembly 2 nor into the water tank 3. Thus, this part of the water forms a water seal in the connecting water pipe 5, preventing steam from flowing back into the water tank 3 through the connecting water pipe 5, thereby achieving unidirectional steam flow control.

[0052] In some embodiments, the height of the inlet 211 is lower than or equal to the height of the outlet 31. That is, the height of the end of the water pipe 5 connected to the water tank 3 is not lower than the height of the end of the water pipe 5 connected to the steam assembly 2. Thus, without applying additional pressure to the water tank 3, the water in the water tank 3 can flow to the steam assembly 2 under atmospheric pressure.

[0053] Specifically, such as Figure 5 As shown, the steam assembly 2 is located at the left end, and the water tank 3 is located at the right end. The height of the inlet 211 of the steam assembly 2 at the left end is lower than the height of the outlet 31 of the water tank 3 at the right end. The connecting water pipe 5 connects the outlet 31 and the inlet 211. When the water in the water tank 3 flows to the connecting water pipe 5, under the action of atmospheric pressure, the water levels at both ends of the connecting water pipe 5 tend to be parallel in the same horizontal plane. Thus, as the water in the steam assembly 2 is consumed, the water in the water tank 3 can continuously flow into the steam assembly 2 through the connecting water pipe 5, thereby realizing the continuous production of steam and avoiding the discontinuous phenomenon of steam discharge.

[0054] In some embodiments, the main unit 1 is equipped with a water nozzle 4, and the water nozzle 4 is provided with a top opening member 41. The top opening member 41 is used to open the water outlet 31 when the water tank 3 is installed on the main unit 1. That is, the top opening member 41 at the water nozzle 4 can extend into the water outlet 31, thereby connecting the water nozzle 4 and the water outlet 31. The water outlet 31 is connected to the connecting water pipe 5 through the water nozzle 4, thereby realizing the connection between the water tank 3 and the connecting water pipe 5.

[0055] Specifically, such as Figure 5 As shown, a valve 32 is provided at the outlet 31 of the water tank 3. When the water tank 3 is not installed on the main unit 1, the valve 32 can close the outlet 31, so that the water in the water tank 3 will not flow out from the outlet 31. When the water tank 3 is installed at the outlet 31, the outlet 31 can be aligned with the top opening member 41. As the two approach each other, the top opening member 41 presses against the bottom of the valve 32 and pushes the valve 32 upward into the water tank 3. Thus, the outlet 31 is connected to the water nozzle 4. When it is necessary to remove the water tank 3 from the water nozzle 4, the water tank 3 can be pulled upward. As the top opening member 41 is removed from the outlet 31, the valve 32 can fall back to the outlet 31 and close it. Thus, the water in the water tank 3 cannot continue to flow out from the outlet 31, which is conducive to the disassembly of the water tank 3. The structure is simple and easy to install.

[0056] In some embodiments, the heating power of the first heating element 22 is P, the minimum cross-sectional area of ​​the steam channel 212 is S, and the following condition is met: P / S≤500, where P is in W and S is in cm. 2The P / S value can be set to 100, 150, 200, 250, 300, 350, 400, 450, 500, or other values ​​where P / S ≤ 500. By controlling the P / S value, the steam flow rate can be controlled, ensuring optimal steam discharge and reducing safety hazards, preventing excessive steam pressure that could lead to explosions or other safety issues.

[0057] In some embodiments, the first heating element 22 is configured to heat intermittently. That is, the first heating element 22 may be configured to stop heating after heating for a period of time, using residual heat to evaporate water into steam, and the first heating element 22 may continue heating when the residual heat is insufficient to convert water into steam.

[0058] Intermittent heating can be achieved using an electronic control scheme. For example, a temperature sensor and a thermostat 23 can be installed within the steam assembly 2. The temperature sensor can monitor the temperature of the first heating element 22 in real time and transmit the temperature information to the thermostat 23. When the temperature within the heating chamber 213 is higher than or equal to the temperature at which water evaporates into steam, the thermostat 23 can control the first heating element 22 to stop heating, thus utilizing residual heat to heat the water. When the temperature within the heating chamber 213 is lower than the temperature at which water evaporates into steam, the thermostat 23 can control the first heating element 22 to continue heating. This ensures continuous steam discharge while saving energy and preventing excessive pressure within the steam assembly 2, reducing safety hazards.

[0059] In some embodiments, the heating time of the first heating element 22 is t1, the weight of the first heating element 22 is m, and the following conditions are met: m / t1≤20, where t1 is in seconds and m is in grams; for example, the value of m / t1 can be set to 10, 12, 13, 15, 16, 17, 19, 20, or other values ​​where m / t1≤20.

[0060] And / or, in other embodiments, the pause duration of the first heating element 22 is t2, the water volume in the heating chamber 213 is L, and satisfies: t2 / L≤3, where t2 is in seconds and L is in mL. For example, the value of t2 / L can be set to 1, 1.5, 2, 2.5, 3, or other values ​​where t2 / L≤3.

[0061] Therefore, by controlling the ratio of the weight of the first heating element 22 to the heating time, and by controlling the ratio of the pause time of the first heating element 22 to the amount of water in the heating chamber 213, continuous steam production and discharge can be achieved, while reducing energy consumption and safety hazards.

[0062] In some embodiments, the main unit 1 is provided with an airflow drive 12 and a second heating element 13. The airflow drive 12 is used to drive the airflow passing through the second heating element 13 to circulate within the cooking cavity 11. The airflow drive 12 and the second heating element 13 can be installed within the cooking cavity 11 so that when the second heating element 13 is heating, the airflow drive 12 drives the airflow passing through the second heating element 13 into the cooking cavity 11 and drives the airflow between the second heating element 13 and the cooking cavity 11 to circulate, using the heat generated at the second heating element 13 to heat the food. Alternatively, the airflow drive 12 and the second heating element 13 can also be installed outside the cooking cavity 11, and heated airflow can be delivered into the cooking cavity 11 through an airflow channel communicating with the cooking cavity 11, causing the airflow between the second heating element 13 and the cooking cavity 11 to circulate, both achieving the effect of heating the food within the cooking cavity 11.

[0063] In practical design, the airflow drive component 12 can be constructed as an airflow fan, and a drive motor 14 connected to the airflow fan can be installed inside the main unit 1 to drive the airflow fan to rotate, thereby driving the airflow; the second heating component 13 can be constructed as a heating tube to heat the surrounding airflow when the heating tube is working. In this way, the airflow drive component 12 can drive the heated airflow near the heating tube into the cooking cavity 11 and form an airflow circulation, thereby heating the food. Figure 4 As shown, the airflow drive 12 is located at the top of the cooking cavity 11, while the second heating element 13 is located below the airflow drive 12. The airflow drive 12 can drive the airflow at the second heating element 13 to flow downwards to the area where food is placed in the cooking cavity 11 and form an airflow circulation, thereby heating the food with airflow.

[0064] In addition, in some other embodiments, a third heating element 15 and a second heating element 13 may be provided to heat the cooking cavity 11 together. For example, the second heating element 13 may be provided at the top of the cooking cavity 11, while the third heating element 15 may be provided at the bottom of the cooking cavity 11 to enhance heating efficiency.

[0065] In some embodiments, the first heating element 22 includes a water boiling section 221, a heat transfer section 222, and a heating section 223. The water boiling section 221 is disposed at the bottom of the heating chamber 213. The water boiling section 221, the heat transfer section 222, and the heating section 223 are connected sequentially in the vertical direction. The heat from the heating section 223 is suitable for being introduced into the heating chamber 213 through the heat transfer section 222 from the water boiling section 221, thereby achieving the heating of water.

[0066] Specifically, the boiling section 221 is used to hold water and heat it to boiling point, the heating section 223 is used to generate heat, and the heat transfer section 222 is mainly used to conduct the heat generated by the heating section 223 to the boiling section 221, so that the temperature of the boiling section 221 can be increased to heat the water. (See attached diagram) Figure 8 As shown, the water boiling section 221 is located at the bottom of the heating chamber 213 to form the bottom structure of the heating chamber 213. The upper surface of the water boiling section 221, i.e. the inner bottom wall of the heating chamber 213, can directly contact the water to facilitate the transfer of heat to the water for heating. The water boiling section 221, the heat transfer section 222, and the heating section 223 are connected sequentially in the vertical direction, i.e., the water boiling section 221 is located on the upper side, the heating section 223 is located on the lower side, and the heat transfer section 222 is located between the water boiling section 221 and the heating section 223 to transfer the heat from the heating section 223 to the water boiling section 221, and then through the water boiling section 221 into the heating chamber 213 to heat the water in the heating chamber 213 to produce steam. Thus, the production of steam is realized.

[0067] It should be noted that the cooking device 100 also includes a frying bucket assembly 6, meaning that food can be placed inside the frying bucket assembly 6, which is removably installed in the cooking cavity 11. The main unit 1 has a cooking cavity 11, and the frying bucket assembly 6 is removably installed in the cooking cavity 11. The main unit 1 has a pull-out opening, allowing the frying bucket assembly 6 to extend into or be pulled out of the cooking cavity 11.

[0068] like Figure 1 and Figure 2 As shown, the pull-out port is located on the front side of the main unit 1, so that the user can manually pull the frying bucket assembly 6 from the front. The frying bucket assembly 6 forms a food placement cavity. After the frying bucket assembly 6 extends into the cooking cavity 11, the food placement cavity is located in the cooking cavity 11, so that the heating airflow can enter the food placement cavity to heat the food, and steam can also enter the food placement cavity to solve the problem of dry food.

[0069] Therefore, food can be heated by placing it in the frying bucket assembly 6 and installing the frying bucket assembly 6 in the cooking cavity 11. At the same time, the frying bucket assembly 6 can be pulled out and installed in the cooking cavity 11, making the operation simple and convenient.

[0070] According to the cooking device 100 of this utility model embodiment, the steam channel 212 and the heating chamber 213 share a partition wall 214, and the steam inlet 2121 connects the steam channel 212 and the cooking chamber 11 at the top, thereby effectively shortening the length of the steam channel 212 and accelerating the speed at which steam is discharged from the heating chamber 213.
