Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a steaming appliance. Background Technology

[0002] To increase the steam output speed of the electric steamer, an independent water tank is installed, and the water flow is controlled to direct a small amount of water to the heating zone for rapid boiling. In controlling the water flow, a float is used to control the opening and closing of the water circuit due to buoyancy, thereby ensuring the stability of the water volume in the heating zone.

[0003] However, such a setup requires multiple components to work together for water circuit control, making assembly complex and costly. Furthermore, most floats are made of hollow plastic parts, and because their installation location is close to the heat source, the returning hot water will heat the float for a long time, causing the float to be corroded and plasticized, which will affect the health of users. Utility Model Content

[0004] Therefore, it is necessary to provide a steaming appliance that, on the one hand, maintains rapid boiling of the steam generating chamber with a small amount of water to increase the steam output speed; on the other hand, simplifies the structure, reduces assembly difficulty, and improves safety in use.

[0005] A steaming appliance includes a base assembly and a water tank assembly. The base assembly has a steam generating chamber with a water inlet. The water tank assembly has a water storage chamber and a water replenishment chamber. The water storage chamber is a closed cavity with a water outlet. The water storage chamber and the water replenishment chamber are connected through the water outlet. The water replenishment chamber has a water replenishment port, which is connected to the steam generating chamber through a connecting channel. The water replenishment chamber is connected to the outside air. The lowest point of the water inlet is lower than the highest point of the water outlet. The highest point of the connecting channel is not greater than the highest point of the water outlet, so that the liquid level in the water replenishment chamber is the same as the liquid level in the steam generating chamber.

[0006] Understandably, the steam generating chamber and the water supply chamber form a communicating vessel structure, with their liquid levels changing synchronously. As the liquid level in the steam generating chamber gradually decreases due to heating and boiling, the liquid level in the water supply chamber also decreases until it falls below the highest point of the outlet. At this point, outside air enters the water storage chamber through the outlet, causing the air pressure inside and outside the water storage chamber to reach equilibrium. At this time, water in the water storage chamber flows to the water supply chamber under its own gravity, and water in the water supply chamber flows to the steam generating chamber through the water supply inlet and connecting channel, thus achieving water supply to the steam generating chamber. As the liquid level in the steam generating chamber gradually rises, the liquid level in the water supply chamber also gradually rises until it is no lower than the highest point of the outlet. At this point, a negative pressure zone is formed in the water storage chamber, preventing water from flowing further into the water supply chamber, thus stopping water supply. This steaming appliance utilizes the change in liquid level in the water supply chamber relative to the highest point of the outlet and the pressure change in the water storage chamber within the closed cavity to maintain a consistently low water level in the steam generating chamber, ensuring stable water flow control. Compared to control methods using floats or pumps, this design eliminates the need for external structures to assist in control, significantly simplifying the structure and reducing assembly difficulty. In particular, the elimination of plastic floats for water control eliminates safety concerns arising from the plasticizing of plastic due to continuous heating in hot water, thus enhancing the user experience.

[0007] In some embodiments, the maximum height of the water outlet does not exceed 70% of the height of the steam generating chamber. That is, this limitation ensures that the amount of water in the steam generating chamber is kept low, which is conducive to rapid steam generation.

[0008] In some embodiments, the water tank assembly includes a water trough and an open water tank, with the outlet located at or near the open of the water tank; the water trough is connected to the open and together with the water tank forms the water storage cavity, and a portion of the water trough located outside the water storage cavity defines the water replenishment cavity.

[0009] In other words, the water tank is covered at the opening of the water tank to separate the water storage chamber and the water replenishment chamber; and it is precisely because of the water tank that the opening edge of the water tank can be pressed against the bottom of the water tank after the water tank assembly is turned over, ensuring the sealing of the water storage chamber at the opening and reducing the risk of leakage.

[0010] In some embodiments, the edge of the opening is recessed along the height direction of the water tank to form the water outlet.

[0011] This configuration ensures that the outlet is positioned lower than the water supply chamber, resulting in a relatively low maximum height of the outlet. This further reduces the amount of water in the steam generation chamber and increases the steam output speed.

[0012] In some embodiments, the highest height H1 of the outlet is 25%-55% of the depth H2 of the water tank.

[0013] In other words, further limiting the maximum height of the water outlet can maintain a relatively low water volume in the steam generating chamber, which not only significantly reduces the risk of burning dry but also facilitates faster boiling; in addition, it makes it easier to replenish water quickly.

[0014] In some embodiments, the water tank assembly further includes a cover plate connected to the water tank and / or the water trough, the cover plate covering the portion of the water trough located outside the water tank.

[0015] In other words, by using the cover plate, external impurities can be reduced from entering the water tank, keeping the water in the water supply chamber and the water storage chamber clean.

[0016] In some embodiments, the water tank and the water container are snap-fitted together. This design facilitates quick assembly and disassembly of the water tank and the water container, and allows for convenient and timely addition of water to the water container.

[0017] In some embodiments, the base assembly includes a base body and a heating plate; the base body has a cooking area and a mounting part located on the side of the cooking area, the cooking area surrounds the steam generating chamber, the mounting part is used to install the water tank assembly and has a connecting hole, the connecting hole communicates with the connecting channel, the connecting hole communicates with the water inlet and is sealed; the heating plate is located below the steam generating chamber.

[0018] Understandably, since the installation unit is located outside the cooking area, that is, the entire water tank assembly is installed outside the cooking area, keeping it away from the heating plate and high-temperature area, thus reducing the thermal impact on the water tank assembly.

[0019] In some embodiments, the water tank assembly has a downwardly protruding mounting flange at the water outlet, the mounting flange being insertable into the connecting hole, and the mounting flange sealingly engaging with the hole wall of the connecting hole.

[0020] Understandably, the insertion and engagement of the assembly flange and the assembly hole serve to position the water tank assembly relative to the base assembly, facilitating accurate assembly. Furthermore, the sealing engagement between the assembly flange and the wall of the connecting hole improves sealing performance and reduces the risk of leakage.

[0021] In some embodiments, the connecting hole is formed by a vertical recess from the upper surface of the mounting portion, the bottom wall of the connecting hole is provided with a sealing gasket, and the extended end of the mounting flange is pressed against the sealing gasket.

[0022] In other words, the use of sealing gaskets ensures the seal between the assembly flange and the connection hole, thereby reducing the risk of water leakage after the water tank assembly is assembled with the base assembly.

[0023] In some embodiments, the connecting hole and / or the water inlet is provided with an assembly section, the connecting channel includes a connecting pipe, and the end of the connecting pipe is inserted into and sealed with the corresponding assembly section.

[0024] In other words, by using the assembly section, the assembly area with the connecting pipe is increased, thus improving assembly reliability; and, due to the sealing of both, the risk of leakage is reduced.

[0025] In some embodiments, the water tank assembly further includes a sealing structure disposed at the water inlet, the sealing structure being used to seal the water inlet; the base assembly is provided with a connecting hole communicating with the connecting channel, the wall of the connecting hole being provided with a trigger structure, the trigger structure being able to move against the sealing structure to open the water inlet.

[0026] In other words, when the water tank assembly is not installed on the base assembly, the sealing structure seals the water inlet to ensure that the water in the storage chamber and the water supply chamber will not leak; when the water tank assembly is installed on the base assembly, the trigger structure moves to release the seal, allowing the water in the water tank assembly to flow to the steam generation chamber.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0044] Currently, to enable steaming appliances to generate steam quickly, a separate water tank is usually installed, connected to the steam generation chamber via pipelines. By controlling the water flow, a smaller amount of water is directed into the steam generation chamber, facilitating rapid heating and boiling. Water flow control can be achieved using a water pump; alternatively, a float can be installed at the outlet, using buoyancy to control the opening and closing of the water path, thus ensuring a stable water level in the steam generation chamber by replenishing and stopping the water supply.

[0045] However, both pump and float control require the coordination of multiple components, making assembly more complex and costly. For example, using a pump necessitates consideration of its electric control and compatibility with other structures, increasing the number of components and assembly difficulty. Similarly, float control requires coordination with other structures to prevent float misalignment, further complicating assembly. Furthermore, floats are mostly made of hollow plastic; when installed near heat sources, the backflow of hot water can continuously heat the float, causing corrosion and plasticization, potentially impacting user health.

[0046] To address this, one embodiment of this application provides a steaming appliance that, on the one hand, maintains rapid boiling of the steam generating chamber with a relatively small amount of water, thereby increasing the steam output rate; on the other hand, it simplifies the structure, reduces assembly difficulty, and improves safety during use. The specific structure of this steaming appliance is described in detail below.

[0047] Please see Figures 1 to 4 , Figure 7 and Figure 9 In some embodiments, the steaming appliance includes at least a base assembly 10 and a water tank assembly 20. The base assembly 10 has a steam generating chamber 1011 with a water inlet 1013. The water tank assembly 20 has a water storage chamber 201 and a water replenishment chamber 202. The water storage chamber 201 is a closed cavity with a water outlet 203. The water storage chamber 201 and the water replenishment chamber 202 are connected through the water outlet 203. The water replenishment chamber 202 has a water replenishment port 204, which is connected to the steam generating chamber 1011 through a connecting channel 12. The water replenishment chamber 202 is connected to the outside air. The lowest height of the water inlet 1013 is less than the highest height of the water outlet 203, and the highest height of the connecting channel 12 is not greater than the highest height of the water outlet 203, so that the liquid level in the water replenishment chamber 202 is the same as the liquid level in the steam generating chamber 1011.

[0048] Understandably, the water storage chamber 201 supplies water to the water replenishment chamber 202 through the water outlet 203, and the water replenishment chamber 202 supplies water to the steam generating chamber 1011 through the water replenishment port 204. Based on this, the height limitations of the water inlet 1013, the water outlet 203, and the connecting channel 12 cause the steam generating chamber 1011 and the water replenishment chamber 202 to be connected as a communicating vessel structure, thus causing the liquid levels in the steam generating chamber 1011 and the water replenishment chamber 202 to change synchronously. As the liquid level in the steam generating chamber 1011 gradually decreases due to heating and boiling, the liquid level in the water replenishment chamber 202 also gradually decreases. When the liquid level in the water replenishment chamber 202 is lower than the highest point of the water outlet 203, outside air enters the water storage chamber 201 through the water outlet 203, causing the air pressure inside the water storage chamber 201 to reach equilibrium with the air pressure outside the water storage chamber 201. At this time, the water in the water storage chamber 201 flows to the water replenishment chamber 202 under its own gravity, and the water in the water replenishment chamber 202 flows to the steam generating chamber 1011 through the water replenishment port 204 and the connecting channel 12, thereby realizing the water replenishment operation of the steam generating chamber 1011. As the liquid level in the steam generating chamber 1011 gradually rises, the liquid level in the water replenishment chamber 202 also gradually rises until the liquid level in the water replenishment chamber 202 is not lower than the highest point of the outlet 203, that is, the outlet 203 is submerged. At this time, the water in the water replenishment chamber 202 is equivalent to water sealing the outlet 203, and the outside air will not enter the water storage chamber 201. However, due to the reduction of water volume in the water storage chamber 201, the volume above the water increases, causing a negative pressure zone to be formed in the water storage chamber 201, and the water replenishment chamber 202 is at normal pressure, thus preventing the water in the water storage chamber 201 from continuing to flow to the water replenishment chamber 202, and stopping the water replenishment. The cycle continues until the liquid level in the water replenishment chamber 202 is lower than that in the water outlet 203, breaking the negative pressure to replenish water again, and so on.

[0049] In other words, the steaming appliance provided in one embodiment of this application utilizes the change in the liquid level in the water supply chamber 202 relative to the highest height of the outlet 203 and the pressure change in the water storage chamber 201 based on the closed cavity to maintain the same liquid level in the water supply chamber 202 and the steam generating chamber 1011, thereby keeping the steam generating chamber 1011 in a state of low water volume and satisfying the stable control of the water volume in the steam generating chamber 1011. Compared with control methods such as floats or pumps, this setting does not require the introduction of other external structures to assist in control, significantly simplifying the structure and reducing assembly difficulty; in particular, since there is no need to use a float made of plastic material to control the water volume, there is no safety problem caused by the plastic being plasticized by continuous heating of hot water, improving the user experience.

[0050] Please see Figures 1 to 4 , Figure 7In some embodiments, the maximum height of the outlet 203 does not exceed 70% of the height of the steam generating chamber 1011. It is understood that because water replenishment stops when the liquid level in the water replenishment chamber 202 is not lower than the maximum height of the outlet 203, the maximum height of the outlet 203 limits the liquid level in the steam generating chamber 1011. Therefore, if the maximum height of the outlet 203 is higher than the height of the steam generating chamber 1011, it means the liquid level in the steam generating chamber 1011 is higher, i.e., there is more water in the steam generating chamber 1011. This is not conducive to rapid heating and boiling, affecting the steam output rate. Therefore, the maximum height of the outlet 203 needs to be smaller than the height of the steam generating chamber 1011.

[0051] Of course, the maximum height of the outlet 203 should not be too small relative to the height of the steam generating chamber 1011. Since the minimum height of the inlet 1013 of the steam generating chamber 1011 is less than the maximum height of the outlet 203, sufficient space needs to be reserved for the inlet 1013. If the maximum height of the outlet 203 is too small, it will be inconvenient to install the inlet 1013. Furthermore, a small maximum height of the outlet 203 will result in a low liquid level in the steam generating chamber 1011, potentially leading to a risk of the liquid boiling dry and posing a safety hazard. In addition, a small maximum height of the outlet 203 also hinders rapid water replenishment, which can also lead to a risk of the liquid boiling dry.

[0052] In some specific embodiments, the maximum height of the outlet 203 accounts for 20%, 30%, 40%, 50%, 60% or 70% of the height of the steam generating chamber 1011.

[0053] Please see Figure 1 and Figure 7 In actual use, the base assembly 10 includes a base body 11 and a heating plate 13 disposed on the base body 11. The base body 11 surrounds a steam generating chamber 1011, and the heating plate 13 is disposed at the bottom of the steam generating chamber 1011 for heating the water in the steam generating chamber 1011. Because the amount of water in the steam generating chamber 1011 can always be kept at a low level, it can boil more quickly under the heating action of the heating plate 13, thereby increasing the steam generation speed.

[0054] In actual use, the highest height of the water outlet 203 is consistent with the highest liquid level in the steam generating chamber 1011. That is, when the liquid level in the water replenishment chamber 202 is equal to the highest height of the water outlet 203, the water outlet 203 is sealed, and water replenishment stops. At this time, the liquid level in the water replenishment chamber 202 is the highest liquid level. Furthermore, since the water replenishment chamber 202 and the steam generating chamber 1011 form a communicating vessel structure, the highest liquid level in the steam generating chamber 1011 is also consistent with the highest height of the water outlet 203.

[0055] The maximum height of the inlet 1013 can be less than the maximum height of the outlet 203, so that the water in the water supply chamber 202 can flow more smoothly into the steam generating chamber 1011.

[0056] Please see Figures 2 to 7 In some embodiments, the water tank assembly 20 includes a water tank 21 with an opening 2101 and a water trough 22 covering the opening 2101. The water trough 22 and the water tank 21 together form a water storage cavity 201. The portion of the water trough 22 located outside the water storage cavity 201 is defined as a water replenishment cavity 202. The water outlet 203 is located at or near the opening 2101 of the water tank 21. That is, the cross-section of the water tank 21 is smaller than the cross-section of the water trough 22, ensuring that after the water trough 22 is connected to the opening 2101 of the water tank 21, a portion of the water trough 22 still protrudes horizontally relative to the water tank 21. For example... Figure 3 and Figure 5 In the left-right direction, the right part of the water tank 22 protrudes from the water tank 21, and the cavity of this protruding part is used as the water replenishment cavity 202 located outside the water tank 21.

[0057] In some specific embodiments, both the water tank 21 and the water trough 22 have rectangular cross-sections, and the length of the water trough 22 is greater than the length of the water tank 21, causing a portion of the water trough 22 along its own length direction to protrude from the water tank 21. The water replenishment cavity 202 is located only on one side of the water storage cavity 201 along the length direction of the water trough 22. Alternatively, the water tank 21 has a square cross-section, and the water trough 22 has a rectangular cross-section, with a portion of the water trough 22 protruding from the water tank 21 along its own length direction to form the water replenishment cavity 202. Or, both the water tank 21 and the water trough 22 have square cross-sections, in which case one side of the water trough 22 in the left-right direction and one side in the front-back direction both protrude from the water tank 21, causing the cross-section of the water replenishment cavity 202 to be L-shaped. Of course, the water replenishment cavity 202 can also be arranged around the outer periphery of the water storage tank 21, with the cross-section of the water replenishment cavity 202 being annular. The key is to ensure that a water replenishment cavity 202 is formed on the outside of the water tank 21; this is merely an example.

[0058] In actual use, water is filled into the water tank 21 through the opening 2101, and the water trough 22 is installed at the opening 2101 of the water tank 21. Then, the water tank 21 and the water trough 22 are flipped over as a whole and installed on the base body 11. At this time, the water in the water storage chamber 201 will first flow to the water replenishment chamber 202 under the action of gravitational potential energy, and then flow into the steam generating chamber 1011 along the aforementioned connecting channel 12 and water inlet 1013. When the liquid level in the water replenishment chamber 202 is consistent with the liquid level in the steam generating chamber 1011, and the highest liquid level in the water replenishment chamber 202 is level with the highest point of the water outlet 203, the water in the water storage chamber 201 stops flowing. When the water in the steam generating chamber 1011 boils and evaporates under the heating action of the heating plate 13, causing the highest liquid level in the water replenishment chamber 202 to be lower than the highest point of the water outlet 203, water is automatically replenished. This cycle is repeated.

[0059] When the water tank assembly 20 is flipped, the water tank 21 is pressed against the bottom of the water tank 22 under its own gravity to ensure the sealing of the bottom of the water storage cavity 201, prevent air from flowing in from the connection gap between the water tank 22 and the water tank 21 and disrupting the negative pressure balance, and reduce the risk of water leakage.

[0060] Of course, once the water in the water storage chamber 201 has been consumed to a certain extent, the water tank assembly 20 can be completely disassembled and refilled for reuse. For example, a liquid level sensor can be installed in the water storage chamber 201. When the water level in the water storage chamber 201 drops to trigger the liquid level sensor, it will indicate that water should be added to the water storage chamber 201.

[0061] The edge of the opening 2101 is recessed along the height direction of the water tank 21 to form the water outlet 203. This arrangement ensures that the water outlet 203 is positioned lower than the water supply chamber 202, thus ensuring a relatively low maximum height of the water outlet 203. This further reduces the amount of water in the steam generating chamber 1011, increasing the steam output speed. Furthermore, this arrangement positions the water outlet 203 closer to the opening 2101 than the water tank 21, allowing for more water to be filled into the water tank 21 and reducing the risk of leakage. The cross-section of the water outlet 203 along its axial direction can be quadrilateral, elliptical, or circular, etc.

[0062] like Figure 4 and Figure 7As shown, the maximum height H1 of the outlet 203 occupies 25%-55% of the depth H2 of the water tank 22. The change in the maximum height of the outlet 203 relative to the depth of the water tank 22 determines the liquid level in the water replenishment chamber 202, which is limited by the water tank 22, and thus affects the liquid level in the steam generating chamber 1011. As mentioned above, if the maximum height of the outlet 203 is too large, it will affect the steam output speed of the steam generating chamber 1011; conversely, if it is too small, it will not only be detrimental to water output but also pose a safety hazard. Therefore, by further limiting the maximum height of the outlet 203, the water volume in the steam generating chamber 1011 can be kept at a relatively low level, which not only significantly reduces the risk of boiling dry but also significantly facilitates faster boiling. Moreover, this setting ensures the water output speed at the outlet 203, which is conducive to rapid water replenishment.

[0063] In some specific embodiments, the highest height H1 of the outlet 203 occupies 25%, 32%, 38%, 45%, 52%, or 55% of the depth H2 of the water tank 22.

[0064] Please continue reading. Figures 2 to 7 In some embodiments, the water tank assembly 20 further includes a cover plate 23 connected to the water tank 21, which covers the portion of the water tank 22 located outside the water tank 21. The cover plate 23 reduces the entry of external impurities into the water tank 22, keeping the water in the water replenishment chamber 202 and the water storage chamber 201 clean.

[0065] The cover plate 23 is arranged in a ring shape, and the cross-sectional area of ​​the cover plate 23 corresponding to the water replenishment cavity 202 is increased to match the size of the water replenishment cavity 202. The cover plate 23 is integrally formed with the water tank 21. The water tank 21 has an assembly part 211 near the opening 2101 that extends into the water tank 22 to fit. The water tank 22 covers the outside of the assembly part 211, and the cover plate 23 is connected to the side of the assembly part 211 away from the opening 2101 along the height direction of the water tank 21.

[0066] Of course, the cover plate 23 can also be glued and fixed to the water tank 21, or the cover plate 23 can be connected to the opening of the water trough 22, or the cover plate 23 can be snap-fitted to both the water tank 21 and the water trough 22. For example, the opening of the water trough 22 is provided with a first insertion slot, the water tank 21 and its outer wall are provided with a second insertion slot, the lower surface of the cover plate 23 is provided with a first insertion block, and the inner ring wall of the cover plate 23 is provided with a second insertion block. The first insertion block is inserted into the first insertion slot, and the second insertion block is inserted into the second insertion slot to satisfy the assembly of the cover plate 23 relative to the water trough 22 and the water tank 21. This is only an example.

[0067] Alternatively, based on the setting of the cover plate 23, a sealing gasket 115 can be pressed between the water tank 21 and the water trough 22 to surround the outer periphery of the water storage cavity 201, so as to maintain the sealing of the water storage cavity 201 at the opening 2101 and reduce the risk of water leakage.

[0068] Alternatively, the water tank 22 includes a threaded connection portion and a recessed portion located outside the threaded connection portion. The threaded connection portion is threadedly connected to the water tank 21 to jointly enclose a water storage cavity 201, and the recessed portion encloses a water replenishment cavity 202. A notch is provided between the threaded connection portion and the recessed portion to communicate with the water outlet 203, so as to connect the water storage cavity 201 and the water replenishment cavity 202. In this case, the cross-sections of both the water tank 21 and the threaded connection portion are circular.

[0069] Please see Figures 3 to 6 In some embodiments, the water tank 21 and the water trough 22 are detachably connected, facilitating their assembly and disassembly, and thus making it easier to add water to the water tank 21. For example, the water tank 21 and the water trough 22 are snap-fitted together. The part of the water tank 21 that mates with the water trough 22 serves as an assembly part 211, which snaps into the wall of the water trough 22. Specifically, the outer side of the assembly part 211 is provided with a plurality of first limiting blocks 213 arranged at intervals along the circumference of the assembly part 211, and the wall of the water trough 22 is provided with a plurality of second limiting blocks 221 arranged at intervals along its own circumference. A sliding groove is provided between any two adjacent first limiting blocks 213 and any two adjacent second limiting blocks 221. The water tank 22 can slide into the water tank 21 along the height direction through the sliding groove, causing each second limiting block 221 to move above each first limiting block 213. Then, the water tank 22 can be moved along the length direction of the water tank 22, so that the top of each first limiting block 213 abuts against a corresponding second limiting block 221, thus satisfying the snap-fit ​​engagement between the water tank 22 and the water tank 21. At this time, the edge of the opening 2101 of the water tank 21 abuts against the bottom of the water tank 22 to ensure the sealing state of the opening 2101 of the water storage cavity 201 after flipping.

[0070] Alternatively, a snap-fit ​​mechanism with a slot and a protrusion can be used. The key is to ensure a detachable connection between the water tank 21 and the water trough 22.

[0071] Please see Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10In some embodiments, the base body 11 has a cooking zone 111 and a mounting part 112 located outside the cooking zone 111. The cooking zone 111 surrounds a steam generating chamber 1011, and the mounting part 112 is used to mount the water tank assembly 20. It is understood that the cooking zone 111 mainly supports structures such as the drip tray, steaming rack 30, and pot lid 40. The steam generated by the steam generating chamber 1011 flows upward to act on the food on the steaming rack 30, achieving steaming cooking. Since the mounting part 112 is located outside the cooking zone 111, the water tank assembly 20 is entirely mounted outside the cooking zone 111, keeping it away from the heating plate 13 and high-temperature areas, reducing the thermal impact on the water tank assembly 20. In actual use, the steaming appliance also includes a control panel 14, which has control buttons for adjusting the cooking status of the steaming appliance.

[0072] Please see Figure 2 , Figure 8 and Figure 9 Furthermore, the mounting section 112 is provided with a connecting hole 1012, which communicates with the connecting channel 12. When the water tank assembly 20 is installed on the mounting section 112, the connecting hole 1012 communicates with and seals the water inlet 204. In actual use, the base body 11 can be provided with a baffle ring in the middle of the cooking area 111, thereby forming a steam generating chamber 1011. The steam generating chamber 1011 is provided with a water inlet 1013 in the baffle ring, and the connecting channel 12 connects the water inlet 1013 and the connecting hole 1012, eliminating the need for frequent disassembly. The base body 11 is also provided with an assembly cavity, in which the heating plate 13 and the connecting channel 12 are housed, improving safety. Due to the sealing fit between the connecting hole 1012 and the water inlet 204, the risk of leakage can be reduced, ensuring that the water flowing out of the water inlet 204 only flows along the connecting channel 12 to the steam generating chamber 1011.

[0073] In some specific embodiments, both the connecting hole 1012 and the inlet 1013 are provided with assembly sections 114. The connecting channel 12 includes a connecting pipe, the end of which is inserted into and sealed with the corresponding assembly section 114. Specifically, the assembly section 114 at the connecting hole 1012 protrudes downward from the connecting hole 1012, and the assembly section 114 at the inlet 1013 protrudes away from the steam generating chamber 1011. By using the assembly section 114, the assembly area with the connecting pipe is increased, thereby improving assembly reliability; moreover, a larger contact area means a larger sealing area, improving sealing performance and reducing the risk of leakage. Of course, a sealing ring can also be pressed between the connecting pipe and the assembly section 114. The assembly section 114 has a cavity for connecting the inlet 1013 or the connecting hole 1012 for water flow. The assembly section 114 can also be L-shaped with rounded corners to reduce the bending area of ​​the connecting pipe. The shape of the assembly section 114 at the inlet 1013 and the shape of the assembly section 114 at the connecting hole 1012 can be the same or different, depending on the actual assembly requirements.

[0074] The assembly section 114 is integrally formed with the part that forms the connecting hole 1012 or the water inlet 1013.

[0075] Alternatively, the assembly section 114 may be provided only at the connecting hole 1012, or only at the water inlet 1013.

[0076] Please see Figures 1 to 6 In some embodiments, the water tank assembly 20 has a downwardly protruding mounting flange 24 at the water inlet 204. The mounting flange 24 can be inserted into the connecting hole 1012, and the mounting flange 24 is sealed to the wall of the connecting hole 1012. Specifically, the water inlet 204 is located at the bottom of the water tank 22, and the mounting flange 24 extends downward from the lower surface of the water tank 22, penetrating the mounting flange 24 axially. It can be understood that the insertion and engagement of the mounting flange 24 with the mounting hole serves to position the water tank assembly 20 relative to the base assembly 10, facilitating accurate assembly. Furthermore, the mounting flange 24 effectively extends the axial length of the water inlet 204, guiding the water flowing through it and reducing the risk of leakage during water replenishment. In addition, the sealing engagement of the mounting flange 24 with the wall of the connecting hole 1012 improves sealing and reduces the risk of leakage.

[0077] like Figure 2As shown, the connecting hole 1012 is further recessed downwards in the vertical direction from the upper surface of the mounting portion 112. A sealing gasket 115 is provided at the bottom of the connecting hole 1012, and the extended end of the mounting flange 24 is pressed against the sealing gasket 115. That is, by using the sealing gasket 115, the sealing between the mounting flange 24 and the connecting hole 1012 is ensured, thereby reducing the risk of water leakage after the water tank assembly 20 is assembled relative to the base assembly 10.

[0078] It should be added that the extended end of the mounting flange 24 is the end of the mounting flange 24 that is axially away from the water supply cavity 202 along the water supply port 204.

[0079] The connecting hole 1012 is a stepped hole, including a large-diameter section and a small-diameter section. An annular pressing end face is provided between the large-diameter section and the small-diameter section, and the sealing gasket 115 can be adhered to this pressing end face. The sealing gasket 115 has a through hole connecting the large-diameter section and the small-diameter section, facilitating water flow. The inner diameter of the mounting flange 24 is larger than the hole diameter of the small-diameter section, and the outer diameter of the mounting flange 24 is smaller than the hole diameter of the large-diameter section, so that the mounting flange 24 is inserted into the large-diameter section and pressed against the sealing gasket 115.

[0080] Alternatively, a rubber sleeve can be fitted on the outer side of the mounting flange 24. When the water tank assembly 20 is installed on the base assembly 10, the water tank assembly 20 is pressed against the mounting part 112 under its own weight, and the mounting flange 24 is pressed against the pressing end face of the connecting hole 1012 by the rubber sleeve, or pressed tightly and sealed with the hole wall of the connecting hole 1012.

[0081] In some embodiments, the small-diameter section of the connecting hole 1012 extends to a mounting section 114, which facilitates insertion and mating with the connecting channel 12.

[0082] Please see Figures 1 to 5 , Figure 8 In some embodiments, the water tank assembly 20 further includes a sealing structure 25 located at the water inlet 204, which seals the water inlet 204. The base assembly 10 has a connecting hole 1012 with a connecting channel 12, and a trigger structure 113 is provided. The trigger structure 113 can move by pressing against the sealing structure 25 to open the water inlet 204. That is, when the water tank assembly 20 is not installed on the base assembly 10, the sealing structure 25 seals the water inlet 204 to ensure that water in the water storage chamber 201 and the water inlet chamber 202 will not leak. When the water tank assembly 20 is installed on the base assembly 10, the trigger structure 113 can move by pressing against the sealing structure 25 to release the seal, facilitating the flow of water in the water tank assembly 20 to the steam generating chamber 1011.

[0083] In some specific embodiments, an annular trigger structure 113 protrudes upward along its own axial direction at the pressing end face of the connecting hole 1012, and the sealing structure 25 is installed at the mounting flange 24. When the mounting flange 24 is inserted vertically downward into the connecting hole 1012, the trigger structure 113 can touch the sealing structure 25 and move upward to release the seal.

[0084] Furthermore, the mounting flange 24 has a sealing protrusion 241 protruding radially inward. The sealing structure 25 includes a sealing post 251, a sealing element 252, and an elastic element 253. The sealing element 252 is sleeved on the end of the sealing post 251 near the water supply cavity 202, and the end of the sealing post 251 away from the water supply cavity 202 has a mounting protrusion 2511 protruding from it. The elastic element 253 presses against the end face of the mounting protrusion 2511 and the sealing protrusion 241 opposite to the water supply cavity 202. During installation, the triggering structure 113 moves towards the water supply cavity 202 by contacting the sealing post 251, causing the sealing element 252 to move away from the sealing protrusion 241 to release the seal. After the water tank assembly 20 is disassembled, the sealing post 251 moves downward under the action of the elastic element 253, causing the sealing element 252 to approach and press against the sealing protrusion 241 to achieve a seal.

[0085] The sealing structure 25 can be a one-way valve, and the trigger structure 113 pushes the valve core (i.e. the sealing column 251) of the one-way valve to move to release the sealing.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
