Description

Technical Field

[0002] As people's living standards improve, their demands for product quality also increase. Air fryers, as kitchen appliances labeled as low-fat and healthy, have become popular with many consumers. Current air fryers use a motor to drive fan blades that rotate at high speed within the cooking chamber. Under the action of the heating element, high-speed hot air is generated. This high-speed hot air undergoes efficient convection heat exchange with the food, enabling rapid cooking. Furthermore, air fryers can be equipped with a steam generator to supply steam into the cooking chamber, thus preventing the high-speed hot air from removing moisture from the surface and interior of the food, which could result in a dry and tough texture.

[0003] However, when the air fryer's placement platform or the air fryer itself is tilted, the water flow in the vaporization chamber will flow to one side, causing uneven water distribution and other problems. This can lead to dry burning in the vaporization chamber, damage to the steam generator, and affect the lifespan and safety of the air fryer. There is room for improvement. Utility Model Content

[0042] The following is for reference. Figures 1-9 The cooking device 100 according to the present invention has a simple structure, ensures a good user experience, and can avoid problems such as dry burning in the vaporization chamber 23, thus extending the service life of the steam generator 2 and extending the service life of the cooking device 100, and ensuring the safety of the cooking device 100.

[0043] like Figures 1-9 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generator 2, and a temperature control component 6.

[0044] The main body 1 of the device has a cooking chamber 11. The steam generator 2 includes a housing 26 and a first heating element 4. A vaporization chamber 23 is formed inside the housing 26. The housing 26 has a water inlet path 21 and a steam path 25 communicating with the vaporization chamber 23 on both sides along the horizontal direction. The steam path 25 is connected to the cooking chamber 11. The first heating element 4 is used to heat the bottom of the vaporization chamber 23. The temperature control component 6 is located on the side of the vaporization chamber 23 away from the water inlet path 21. The temperature control component 6 is configured to control the first heating element 4 to stop heating when the temperature of the vaporization chamber 23 exceeds the set temperature.

[0045] The cooking equipment 100 can be an air fryer, steam oven, or other type of oven, used for defrosting, frying, cooking, and baking food. It has an internal cavity that can be used to hold food. Users can put food into the cavity and then perform defrosting, frying, cooking, and baking operations to meet different user needs.

[0046] Specifically, the main body 1 is the shell structure of the cooking device 100, which includes a cooking cavity 11, etc. The cooking cavity 11 has an opening that opens to one side, and a cooking bucket 13 is installed inside the cooking cavity 11. The cooking bucket 13 is retractable relative to the cooking cavity 11, so that the user can pull the cooking bucket 13 out of the main body 1 to put food into the cooking bucket 13, and can put the cooking bucket 13 into the cooking cavity 11 through the opening to put the food to be cooked into the cooking cavity 11. It is convenient to use. The cooking device 100 is also provided with a steam generator 2, which can be used to evaporate water into steam to replenish the moisture of the food, prevent the food from being too dry, and improve the taste of the food.

[0047] Furthermore, the steam generator 2 is provided with a housing 26, which is located on the outermost side of the steam generator 2. The steam generator 2 can be installed with the equipment body 1 through the housing 26, and the housing 26 can also provide installation points for the other structures of the steam generator 2. The housing 26 can form a vaporization chamber 23 and a water inlet path 21, etc. The water inlet path 21 is connected to the vaporization chamber 23, and the steam path 25 is also connected to the vaporization chamber 23. The water inlet path 21 and the steam path 25 are respectively connected to the two sides of the vaporization chamber 23 in the horizontal direction. A water inlet 212 is formed at the end of the water inlet path 21 away from the vaporization chamber 23. The user can inject water into the water inlet 212 to inject water into the vaporization chamber 23 through the water inlet path 21.

[0048] The water in the vaporization chamber 23 can generate steam after heating. The end of the steam flow path 25 away from the vaporization chamber 23, namely the outlet end 252 of the steam flow path, is connected to the cooking chamber 11. This allows the steam in the vaporization chamber 23 to flow into the cooking chamber 11 through the steam flow path 25 to replenish the food with water and improve its taste. The inlet end 251 of the steam flow path is located in the upper area of ​​the vaporization chamber 23, which can prevent water from flowing directly from the steam flow path 25 into the cooking chamber 11 and ensure reliability. The water inlet flow path 21 and the steam flow path 25 are spaced apart and located on both sides of the vaporization chamber 23 in the horizontal direction to ensure the reliability of water injection and steam discharge.

[0049] Furthermore, the steam generator 2 is also equipped with a first heating element 4, which can be constructed as a heating tube. The first heating element 4 can be installed at the bottom of the housing 26 and can be set to be detachable relative to the bottom of the housing 26 for easy maintenance. The first heating element 4 can be used to heat the bottom of the vaporization chamber 23. After the user injects water into the vaporization chamber 23 through the water inlet flow path 21, the water flow gathers at the bottom of the vaporization chamber 23 under the action of gravity, and the first heating element 4 can heat the bottom of the vaporization chamber 23. That is, the first heating element 4 can heat the water flow in the vaporization chamber 23, so that the water flow can evaporate into steam and be transported into the cooking chamber 11. The structure is simple, the installation cost is low, and the reliability of providing steam to the cooking equipment 100 can be guaranteed.

[0050] In addition, the cooking device 100 is also equipped with a temperature control component 6. The temperature control component 6 is located on the side of the vaporization chamber 23 away from the water inlet flow path 21, that is, the temperature control component 6 is located on the same side as the steam flow path 25, which improves the space utilization. The temperature control component 6 is electrically connected to the first heating element 4, so that the temperature control component 6 can control the operating status of the first heating element 4, and the temperature control component 6 can detect the temperature of the vaporization chamber 23.

[0051] When the first heating element 4 operates to heat the water flow in the vaporization chamber 23, the temperature inside the vaporization chamber 23 rises. When the water flow in the vaporization chamber 23 dries up, or when the cooking device 100 tilts towards the water inlet path 21, resulting in no water flow at the bottom of the vaporization chamber 23, the temperature control component 6 can detect that the temperature inside the vaporization chamber 23 exceeds the set temperature. In this way, it can control the first heating element 4 to stop heating, so as to avoid problems such as dry burning in the vaporization chamber 23, extend the service life of the steam generator 2, and thus extend the service life of the cooking device 100, ensuring the safety of using the cooking device 100.

[0052] The cooking device 100 according to this utility model embodiment is provided with a steam generator 2, which has a simple structure and can improve the taste of cooked food, thereby improving the user experience. In addition, a temperature control component 6 is provided on the side of the vaporization chamber 23 away from the water inlet flow path 21. When the temperature of the vaporization chamber 23 exceeds the set temperature, the first heating element 4 can be controlled to stop heating, thereby avoiding problems such as dry burning in the vaporization chamber 23, extending the service life of the steam generator 2, and thus extending the service life of the cooking device 100, ensuring the safety of the cooking device 100, improving the performance, and expanding the applicability.

[0053] In some embodiments, the temperature control component 6 includes a temperature sensor 61 and a fuse 62. The first heating element 4 is connected to a heating circuit, and the fuse 62 is connected in series in the heating circuit. The temperature sensor 61 is used to detect the temperature of the vaporization chamber 23, and the fuse 62 melts when the temperature value detected by the temperature sensor 61 is greater than the set temperature.

[0054] Specifically, the cooking device 100 is equipped with a temperature control component 6, and as follows: Figure 1 As shown, the temperature control component 6 is equipped with a temperature sensor 61 and a fuse 62. The first connector is installed at the bottom of the vaporization chamber 23 and can be used to heat the water flow in the vaporization chamber 23, so that the vaporization chamber 23 can deliver steam to the cooking chamber 11 through the steam flow path 25. The first heating element 4 is connected to a heating circuit, which can supply power to the first heating element 4 to ensure the operation of the first heating element 4. The fuse 62 can be connected in series in the heating circuit, so that the fuse 62 can control the on and off of the heating circuit. That is, when the fuse 62 is opened, the heating circuit can be disconnected to stop supplying power to the first heating element 4.

[0055] Furthermore, the temperature sensor 61 can be used to detect the temperature inside the vaporization chamber 23. The temperature sensor 61 can be electrically connected to the fuse 62, and the vaporization chamber 23 has a set temperature. When the temperature detected by the temperature sensor 61 is higher than the set temperature, the temperature sensor 61 can control the fuse 62 to melt, thereby stopping the heating circuit from supplying power to the first heating element 4, so that the first heating element 4 stops heating the vaporization chamber 23, ensuring safety in use.

[0056] In some embodiments, the fuse 62 and the temperature sensor 61 are distributed in a horizontal direction, and the fuse 62 is located on the side of the temperature sensor 61 away from the vaporization chamber 23.

[0057] Specifically, the temperature control component 6 is located on the side of the vaporization chamber 23 away from the water inlet flow path 21, and as follows: Figure 1 As shown, the temperature control component 6 is provided with a fuse 62 and a temperature sensor 61. The fuse 62 and the temperature sensor 61 are spaced apart and distributed in a horizontal direction. The fuse 62 can be located on the side of the temperature sensor 61 away from the vaporization chamber 23, that is, the temperature sensor 61 can be located between the vaporization chamber 23 and the fuse 62.

[0058] Furthermore, the temperature sensor 61 is used to detect the temperature inside the vaporization chamber 23. Setting the temperature sensor 61 close to the vaporization chamber 23 can improve the detection accuracy of the temperature sensor 61, thereby improving the reliability of the temperature control component 6. Setting the fuse 62 away from the vaporization chamber 23, that is, away from the first heating element 4, can avoid the high temperature generated by the first heating element 4 from causing the fuse 62 to blow abnormally, thus ensuring the reliability of the fuse 62.

[0059] In some embodiments, the housing 26 is provided with a mounting and fixing part 263, which protrudes from the side of the housing 26 away from the water inlet flow path 21. The temperature sensor 61 and the fuse 62 are both mounted on the mounting and fixing part 263 and extend at least partially outside the mounting and fixing part 263.

[0060] Specifically, the steam generator 2 is provided with a housing 26, and a vaporization chamber 23 is formed inside the housing 26, and as follows: Figure 1 As shown, the housing 26 is provided with a mounting and fixing part 263. The mounting and fixing part 263 is located on the side of the housing 26 away from the water inlet passage 21, and protrudes horizontally towards the side away from the water inlet passage 21, and as shown... Figure 1 As shown, the temperature control component 6 can be installed on the mounting and fixing part 263, that is, the temperature control component 6 can be fixedly connected to the housing 26 through the mounting and fixing part 263.

[0061] Furthermore, the temperature control component 6 is provided with a temperature sensor 61 and a fuse 62. Both the temperature sensor 61 and the fuse 62 can be installed in the mounting part 263. When the temperature sensor 61 and the fuse 62 are installed in the mounting part 263, at least part of them can extend outside the mounting part 263. The parts of the temperature sensor 61 and the fuse 62 extending into the mounting part 263 can be connected to the heating circuit, etc., ensuring the installation reliability of the temperature sensor 61 and the fuse 62, as well as the operational reliability of the temperature sensor 61 and the fuse 62.

[0062] In some embodiments, the housing 26 includes a main housing 261 and a bottom plate 262. The bottom plate 262 is connected to the lower part of the main housing 261 and together with the main housing 261 defines a vaporization chamber 23. The first heating element 4 is used to heat the bottom plate 262. The mounting and fixing part 263 is provided on the main housing 261 and located on the upper side of the bottom plate 262. The temperature sensor 61 and the fuse 62 are respectively in pressure contact with the bottom plate 262.

[0063] Specifically, the steam generator 2 is provided with a housing 26, and as follows: Figure 1 As shown, the housing 26 includes a main housing 261 and a bottom plate 262. The main housing 261 is located at the top and opens downwards. The bottom plate 262 is connected to the bottom of the main housing 261, so that the main housing 261 and the bottom plate 262 can jointly define the vaporization chamber 23 and the water inlet flow path 21, which facilitates production and installation. The first heating element 4 is located below the housing 26, that is, the first heating element 4 can be located below the bottom plate 262. When the first heating element 4 is in operation, it can heat the bottom plate 262. When the water flows in the vaporization chamber 23, it can converge at the bottom of the vaporization chamber 23, which can facilitate the heating of the water flow and ensure heating efficiency.

[0064] Furthermore, a mounting and fixing part 263 is provided on the side of the housing 26 away from the water inlet flow path 21. The mounting and fixing part 263 can be set in the main housing 261 and located on the upper side of the base plate 262. That is, when the main housing 261 and the base plate 262 are connected, the mounting and fixing part 263 can also be connected to the base plate 262. The temperature sensor 61 and the fuse 62 can both be installed in the mounting and fixing part 263 and located above the base plate 262. When the base plate 262 and the main housing 261 are connected, the temperature sensor 61 and the fuse 62 can respectively press against the base plate 262, thereby allowing the base plate 262 to apply a clamping force upward on the temperature sensor 61 and the fuse 62, so that the temperature sensor 61 and the fuse 62 are fixed to the mounting and fixing part 263, ensuring installation reliability, simple arrangement, and compact structure.

[0065] In some embodiments, the mounting and fixing part 263 is provided with two fixing slots 264, which are through in the vertical direction and open towards the base plate 262. The temperature sensor 61 and the fuse 62 are respectively installed in the two fixing slots 264, and their bottoms are pressed against the base plate 262.

[0066] Specifically, a mounting part 263 is provided on the side of the housing 26 away from the water inlet passage 21, and the mounting part 263 protrudes from the side away from the water inlet passage 21. Both the temperature sensor 61 and the fuse 62 can be installed within the mounting part 263. Figure 1 As shown, the mounting and fixing part 263 is provided with two fixing slots 264. The fixing slots 264 are configured to be through in the vertical direction and open downwards, that is, the fixing slots 264 can be opened towards the base plate 262.

[0067] Furthermore, the fuse 62 and the temperature sensor 61 can be placed in two fixing slots 264 respectively, and can be placed in the fixing slots 264 from the bottom opening. After the temperature sensor 61 and the fuse 62 are placed in the fixing slots 264, the base plate 262 can be connected to the mounting fixing part 263, so that the base plate 262 can provide upward support for the temperature sensor 61 and the fuse 62, so that the bottom of the temperature sensor 61 and the fuse 62 can be pressed against the base plate 262, so that the temperature sensor 61 and the fuse 62 are relatively fixed in the mounting fixing part 263, thereby ensuring the installation reliability of the temperature sensor 61 and the fuse 62, and ensuring the connection stability between the temperature sensor 61 and the fuse 62 and the circuit, so as to ensure the operational reliability of the cooking equipment 100.

[0068] In some embodiments, a first seal 265 is provided at the connection between the main housing 261 and the base plate 262.

[0069] Specifically, the steam generator 2 is provided with a housing 26, which is located on the outermost side of the steam generator 2. The housing 26 includes a main housing 261 and a bottom plate 262. The bottom plate 262 is connected to the lower part of the main housing 261 and together with the main housing 261 defines the vaporization chamber 23, and as shown... Figure 1 As shown, a first sealing element 265 is provided at the connection between the main housing 261 and the base plate 262. The first sealing element 265 can be a silicone sealing ring or the like. When the main housing 261 and the base plate 262 are connected, they can apply a pressing force to each other. The first sealing element 265 is located between the main housing 261 and the base plate 262, so that both the main housing 261 and the base plate 262 can press against the first sealing element 265, thereby sealing the connection between the main housing 261 and the base plate 262.

[0070] Furthermore, the water inlet path 21 can inject water into the vaporization chamber 23. A first sealing element 265 is provided at the connection between the main housing 261 and the bottom plate 262 to prevent water in the vaporization chamber 23 from leaking into other structures in the device body 1, which would affect the safety of the cooking device 100. It can also prevent water from leaking into the cooking chamber 11, which would affect the taste of the food and improve the user experience.

[0071] In some embodiments, the main housing 261 and the base plate 262 are detachably connected by at least one connector.

[0072] Specifically, the steam generator 2 is provided with a housing 26, which includes a main housing 261 and a base plate 262. The base plate 262 is connected to the lower part of the main housing 261 and together with the main housing 261 defines the vaporization chamber 23. The main housing 261 and the base plate 262 can be connected by a connector, such as a bolt. The structure is simple and the installation cost is low. Connecting the main housing 261 and the base plate 262 by the connector makes the main housing 261 and the base plate 262 relatively detachable, which facilitates installation and subsequent maintenance, saves maintenance time, and when one of the main housing 261 or the base plate 262 is damaged, only the damaged part needs to be replaced, saving maintenance costs.

[0073] Furthermore, at least one connector is provided, that is, the connector can be one, two or three, etc. In this embodiment, multiple connectors are provided, and multiple connectors are arranged at intervals around the main housing 261, so that multiple places of the main housing 261 and the base plate 262 can be connected by the connectors, thereby improving the connection reliability. In addition, setting multiple connectors can disperse the force between the base plate 262 and the main housing 261, ensuring the reliability of the connector and extending the service life of the connector.

[0074] In some embodiments, the cooking device 100 further includes a water tank assembly 3, which is detachably installed on the device body 1. A water storage cavity 311 is formed inside the water tank assembly 3, and the water storage cavity 311 is connected to the water inlet flow path 21.

[0075] Specifically, the cooking equipment 100 also includes a water tank assembly 3, which is installed on the equipment body 1. The water tank assembly 3 has a water storage cavity 311 inside. The water storage cavity 311 can be selectively connected to the water inlet flow path 21. That is, the user can separate the water tank assembly 3 from the equipment body 1 to disconnect the water storage cavity 311 from the water inlet flow path 21, or the user can install the water tank assembly 3 on the equipment body 1 to connect the water storage cavity 311 with the water inlet flow path 21. When the water tank assembly 3 is installed on the equipment body 1, the water tank assembly 3 is located above the steam generator 2, and the bottom of the water storage cavity 311 can be connected to the water inlet flow path 21.

[0076] Users can store water in the water storage chamber 311. When the water storage chamber 311 is installed above the water inlet flow path 21, the water in the water storage chamber 311 gathers at the bottom of the water storage chamber 311 under the action of gravity. When the water storage chamber 311 is connected to the water inlet flow path 21, the water can flow into the water inlet flow path 21 under the action of gravity. The water inlet flow path 21 is connected to the vaporization chamber 23, so that when the amount of water entering the water inlet flow path 21 reaches a certain level, it can flow into the vaporization chamber 23, and then be heated and evaporated in the vaporization chamber 23 to provide steam to the cooking chamber 11, ensuring the taste of food. Moreover, installing the water storage chamber 311 above the water inlet flow path 21 can ensure that the water flows into the steam generator 2 by gravity, while also shortening the vertical distance between the water tank assembly 3 and the vaporization chamber 23, thereby reducing the space occupied by the steam generator 2 and improving the lightweight of the cooking equipment 100.

[0077] And such as Figure 2 As shown, the water tank assembly 3 is provided with a water tank 31 and a shield 32. A water storage cavity 311 is formed inside the water tank 31 for storing water. A downward-facing water inlet 312 is formed at the bottom of the water tank 31. The shield 32 is movably connected to the water inlet 312, that is, the shield 32 can move relative to the water inlet 312. During the movement, the shield 32 can open or close the water inlet 312. Furthermore, a top opening member 211 is provided at the water inlet 212. The top opening member 211 can be configured as a cylindrical structure and protrude towards the side away from the water inlet 212, so that the top opening member 211 can push open the blocking member 32 to open the water inlet 312. A second sealing member 34 is provided at the water inlet 212. The second sealing member 34 can be constructed as a silicone ring, etc. The water inlet 312 and the water inlet 212 are sealed by the second sealing member 34 pressing against the outer peripheral wall of the water inlet 312.

[0078] During installation, the water inlet 312 of the water tank assembly 3 is extended to the water inlet 212, and the top opening member 211 pushes the blocking member 32 upward, so that the water inlet 312 can be connected to the water inlet 212. In this way, the water in the water tank 31 flows into the water inlet flow path 21 through the water inlet 212 to supply water to the water inlet flow path 21. The blocking member 32 is provided with an elastic member 33, which is a spring or the like. The spring can apply an elastic force to the blocking member 32 toward the top opening member 211, so that when the water tank assembly 3 is removed, the blocking member 32 of the water tank assembly 3 separates from the top opening member 211. The top opening member 211 does not apply force to the blocking member 32. Under the action of the elastic force, the blocking member 32 moves toward the top opening member 211 to close the water inlet 312. The operation is simple and convenient.

[0079] In some embodiments, the steam generator 2 also has an air inlet passage 22, one end of which is connected to the water inlet passage 21, and the other end of which has an air inlet 221. The water outlet 213 of the water inlet passage 21 is lower than the air inlet passage 22.

[0080] Specifically, the upper end of the air intake path 22 is the air inlet 221, which is at the same height as the water inlet 212. The lower end of the air intake path 22 is higher than the water outlet 213 of the water inlet path 21, so that the air intake path 22 and the water outlet 213 can form a height difference to adapt to the water flow control of the water inlet path 21 at different stages.

[0081] Among them, such as Figures 3-5 As shown, when the water tank assembly 3 is connected to the water inlet 212, the water inlet 212 is separated from the air inlet 221, and the water tank assembly 3 can isolate the air inlet 221 of the air intake path 22 from the outside, so that the air in the air intake path 22 remains constant. When the water tank assembly 3 supplies water to the water inlet 212, air can enter the water intake path 21 and the water tank assembly 3 from the lower end of the air intake path 22 along the water flow. The water can flow into the vaporization chamber 23 through the water outlet 213. When the water volume gradually increases, the air cannot enter the water intake path 21 and the water tank assembly 3 from the opposite direction. At this time, the water intake path 21 stops supplying water to the vaporization chamber 23, which can realize the control of the water supply by the air intake path 22. As the water level in the vaporization chamber 23 decreases, water is supplied to the vaporization chamber 23 in a cyclical manner through the above water supply method until the water tank assembly 3 has no water.

[0082] It should also be noted that, such as Figures 3-5 As shown, when the water level in the vaporization chamber 23 is higher than the outlet end 242 of the drain pipe, the steam generated in the vaporization chamber 23 enters the steam flow path 25 through the inlet end 251 of the steam flow path for steam transport. When the water level in the vaporization chamber 23 is lower than the outlet end 242 of the drain pipe, the steam in the vaporization chamber 23 can be transported simultaneously through the inlet end 251 of the steam flow path and the outlet end 242 of the drain pipe.

[0083] Furthermore, when cleaning scale, first add a cleaning agent to the water tank assembly 3, which can be citric acid. Water is supplied to the vaporization chamber 23 through the water tank assembly 3 to maintain a certain liquid level in the vaporization chamber 23. The descaling process is then carried out, and the citric acid dissolves the scale to form a relatively concentrated liquid. The water tank assembly 3 is then removed, and water is quickly added to the equipment body 1 manually from the inlet 212 to dilute the water concentration in the vaporization chamber 23 until it is full. In this way, the liquid level will be above the highest point of the drain pipe 24, and the water will be discharged from the drain pipe 24 and form a siphon principle to continue to pump water from the vaporization chamber 23 until the liquid level is lower than the outlet end 242 of the drain pipe. This completes the descaling and drainage of the vaporization chamber 23.

[0084] In some embodiments, the steam generator 2 further includes a drain pipe 24, the inlet end 241 of which extends into the bottom region of the vaporization chamber 23, and the outlet end 242 of which communicates with the outside of the vaporization chamber 23.

[0085] Specifically, the steam generator 2 is also provided with a drain pipe 24, which is connected to the vaporization chamber 23 and is used to discharge water from the vaporization chamber 23. The drain pipe 24 passes through the side wall of the vaporization chamber 23, with the inlet end 241 of the drain pipe extending to the bottom area inside the vaporization chamber 23 and the outlet end 242 of the drain pipe located outside the vaporization chamber 23. In the vertical direction, the height of the outlet end 242 of the drain pipe is lower than the height of the inlet end 241 of the drain pipe, and there is a highest position between the inlet end 241 and the outlet end 242 of the drain pipe. The highest position of the drain pipe 24 is higher than the inlet end 241 and the outlet end 242 of the drain pipe.

[0086] The drain pipe 24 is designed in this way to create a height difference between its two ends, allowing water to flow from the inlet end 241 to the outlet end 242 of the drain pipe, thus achieving one-way drainage. As water is discharged, a negative pressure is formed inside the drain pipe 24, and water in the vaporization chamber 23 is continuously drawn into the drain pipe 24 for continuous drainage, thereby continuously pumping water through the siphon principle.

[0087] Furthermore, during long-term use of the steam generator 2, scale is prone to form. Water and cleaning agent can be introduced into the vaporization chamber 23 of the steam generator 2 through the inlet 212. The vaporization chamber 23 is heated so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 23. Then, a large amount of water is introduced into the water inlet 21 and the vaporization chamber 23 to dilute the dissolved wastewater. When the water level exceeds the highest position of the drain pipe 24, the wastewater in the vaporization chamber 23 can be discharged sequentially through the inlet end 241 of the drain pipe, the highest position of the drain pipe 24, and the outlet end 242 of the drain pipe. The wastewater is then continuously pumped out through the siphon principle until the wastewater in the vaporization chamber 23 is completely discharged.

[0088] Therefore, by setting a drain pipe 24 with a siphon principle in the vaporization chamber 23, the water after scale cleaning is discharged from the vaporization chamber 23 through the drain pipe 24, thus achieving scale removal and sewage discharge in the vaporization chamber 23. Continuous drainage is achieved through the siphon principle, reducing the need for structures such as water pumps and installation steps. Its structure is simple, easy to operate, and has good performance. Furthermore, regular scale removal and sewage discharge make the steam generator 2 operate efficiently and safely, reducing maintenance frequency and costs, and extending the service life of the steam generator 2.

[0089] The water tank assembly 3 is connected to the water inlet 212, which is spaced apart from the air inlet 221. Air can enter the air intake path 22 through the air inlet 221, and water can enter the vaporization chamber 23 through the air intake path 22. As the water level rises, the vaporization chamber 23... Figure 3 As shown, the water flow can seal the water inlet flow path 21, and as the water in the vaporization chamber 23 evaporates, the water storage chamber 311 can continuously replenish water to the vaporization chamber 23 through the water inlet 212 and the water inlet flow path 21, so that the water level is maintained at the height of the sealed water inlet flow path 21.

[0090] Furthermore, as the water in the vaporization chamber 23 evaporates, the water level drops, such as... Figure 4 As shown, at this time, air can enter through the air intake path 22, causing the water in the water storage chamber 311 to flow downwards to continue water supply. Even when the water in the water intake path 21 decreases to the point where it can no longer supply water to the vaporization chamber 23, the water in the vaporization chamber 23 continues to evaporate through heating, causing the water level in the vaporization chamber 23 to drop. However, there is still water in the water intake path 21. Figure 5 As shown, the vaporization chamber 23 can be isolated from the air intake path 22, preventing steam from being ejected through the air intake 221 or causing damage to the water tank assembly 3, thus ensuring the safety of the cooking equipment 100 and the service life of the water tank assembly 3.

[0091] It should also be noted that when the water level in the vaporization chamber 23 is higher than the height of the inlet end 241 of the drain pipe, the steam generated in the vaporization chamber 23 enters the steam flow path 25 through the inlet end 251 of the steam flow path for steam transport. When the water level in the vaporization chamber 23 is lower than the height of the inlet end 241 of the drain pipe, the steam in the vaporization chamber 23 can be output simultaneously through the outlet end 252 of the steam flow path and the outlet end 242 of the drain pipe.

[0092] In some embodiments, the cooking device 100 further includes a hot air assembly 5, which includes a second heating element 51 and a heating fan 52, the heating fan 52 being used to drive the airflow at the second heating element 51 toward the cooking chamber 11.

[0093] Specifically, the cooking equipment 100 is equipped with a hot air assembly 5. The hot air assembly 5 heats the food in the cooking cavity 11 by delivering hot air, thereby improving the healthiness of the food and meeting different usage needs. The hot air assembly 5 is equipped with a second heating element 51 and a heating fan 52, and both the second heating element 51 and the heating fan 52 are installed in the mounting cavity 12. The second heating element 51 can be constructed as a heating tube or the like, and is used to heat the airflow. The heating fan 52 can drive the hot airflow to move.

[0094] The heating fan 52 is also connected to the drive unit 7, which can be configured as a drive motor, etc. Driven by the drive unit 7, the heating fan 52 can drive the hot airflow near the heating tube to flow, and deliver the hot airflow to the cooking chamber 11. Through continuous hot air circulation, the food is cooked.

[0095] Furthermore, the drive unit 7 is also connected to a cooling fan 71, which is coaxially connected to the heating fan 52. The drive unit 7 drives the cooling fan 71 to rotate, thereby driving the flow of hot air to achieve functions such as heat dissipation. In addition, the hot air assembly 5 can work with the steam generator 2 to deliver steam into the cooking cavity 11, thereby reducing the problem of dry food surface and improving the taste of food.

[0096] In some embodiments, an installation cavity 12 is also formed in the device body 1, the hot air assembly 5 and the steam generator 2 are spaced apart and distributed in the installation cavity 12, and the steam generator 2 is distributed in the side area of ​​the installation cavity 12, and both the hot air assembly 5 and the steam generator 2 are located on the upper side of the cooking cavity 11.

[0097] Specifically, the device body 1 is the shell structure of the cooking device 100, which includes a cooking cavity 11 and a mounting cavity 12, etc. The mounting cavity 12 is used to install other structures of the cooking device 100. The mounting cavity 12 and the cooking cavity 11 are spaced apart, so that the structure in the mounting cavity 12 can be separated from the cooking cavity 11, ensuring the operational reliability of the structure in the mounting cavity 12. The hot air assembly 5 is detachably connected to the mounting cavity 12. The hot air assembly 5 and the steam generator 2 are spaced apart, which can avoid interference between the two and facilitate the separate disassembly and maintenance of the hot air assembly 5 and the steam generator 2.

[0098] Among them, such as Figure 6 As shown, the hot air assembly 5 is located in the central region of the mounting cavity 12, the steam generator 2 is located in the side region of the mounting cavity 12, and both the hot air assembly 5 and the steam generator 2 are located on the upper side of the cooking cavity 11.

[0099] Furthermore, the hot air assembly 5 heats the food by driving hot airflow. The hot air assembly 5 is set in the middle area of ​​the mounting cavity 12, which allows the hot air assembly 5 to cover a large area of ​​the upper part of the cooking cavity 11. This facilitates the hot air assembly 5 to drive a large amount of hot airflow to circulate between the cooking cavity 11 and the mounting cavity 12 in the vertical direction, thereby improving the heating efficiency and cooking effect of the food. The steam generator 2 is located in the side area of ​​the mounting cavity 12 and supplies water to the vaporization cavity 23 through the water storage cavity 311. After the vaporization cavity 23 generates steam, it flows to the cooking cavity 11 through the steam flow path 25, which can replenish the water of the food and ensure the taste of the food.

[0100] Therefore, according to the different functional requirements of the cooking equipment 100, the hot air assembly 5 and the steam generator 2 are reasonably arranged in the space of the installation cavity 12, resulting in a compact structure and complete functions.
