Abstract
Description
[Technical Field]
[0001] FIELD OF THE DISCLOSURE The present disclosure relates to the field of household appliances, and more particularly to a lid assembly and a liquid heating container. [Background technology]
[0002] Currently, existing liquid heating containers, such as health pots, electric kettles, and teapots, are designed with anti-tip lids to prevent water from spilling when the container is tipped. Anti-tip lids generally consist of a three-layer lid body: an upper lid, an intermediate lid, and a lower lid. To ensure smooth exhaust, the anti-tip lid must be equipped with an exhaust system. In conventional exhaust systems for anti-tip lids, steam from the pot enters the chamber of the lower lid through a steam inlet at the bottom of the lower lid, then flows upward between the upper and intermediate lids through a vent hole in the intermediate lid, and finally is exhausted to the outside through a steam outlet in the upper lid. However, in existing anti-tip lids, the steam passes through a handle on the upper lid for lifting the anti-tip lid during the process of being exhausted to the outside, which can easily cause burns to users when using the handle to lift the anti-tip lid. Summary of the Invention [Problem to be solved by the invention]
[0003] An object of the present disclosure is to solve at least one of the technical problems existing in the above-mentioned conventional or related art. [Means for solving the problem]
[0004] To this end, a first aspect of the present invention provides a lid assembly.
[0005] A second aspect of the present invention provides a liquid heating vessel.
[0006] According to a first aspect of the present invention, there is provided a lid assembly for a liquid heating container, the liquid heating container comprising a container body, the lid assembly being fitted over the container body, the lid assembly comprising: a lower lid assembly having a mounting groove with an upward opening, the lower lid assembly having a plurality of vent passages communicating with a space within the container body, an inner lid at least partially fitted to the mounting groove, the bottom walls of the lower lid assembly and the inner lid defining a steam chamber, the steam chamber being communicated with the plurality of vent passages, an upper lid fitted over the lower lid assembly and the inner lid, a steam passage fitted to an edge of the upper lid, a steam guide passage located on the outer peripheral edge of the inner lid and communicating with the steam passage and the steam chamber, and a steam outlet positioned through the edge of the upper lid and communicating with the steam passage.
[0007] The lid assembly in this embodiment includes a lower lid assembly, an inner lid, and an upper lid, with at least a portion of the inner lid attached to the mounting groove of the lower lid assembly. A gap is formed between the lower lid assembly and the bottom wall of the inner lid, forming a steam chamber for steam flow between the bottom wall of the inner lid and the lower lid assembly. The lower lid assembly has a plurality of vent pipes communicating with the steam chamber and the interior of the container body, allowing steam from the container body to enter the steam chamber through the vent pipes. A steam guide passage located on the outer periphery of the inner lid is connected to the steam chamber and the steam passage located on the edge of the upper lid, allowing steam from the steam chamber to enter the steam passage through the steam guide passage and finally be discharged to the outside through a steam outlet connected to the steam passage, thereby achieving normal exhaust function. The steam passage and steam outlet are located on the edge of the upper lid, and the inner lid is located to isolate the upper and middle lids, so that the steam flow path within the lid assembly does not pass through the center of the upper lid, and the handle for lifting the entire lid assembly is usually located in the center of the upper lid, which solves the problem of users being easily burned when lifting the lid assembly with the handle. Furthermore, because the steam outlet is located directly on the edge of the upper lid, steam inside the liquid heating container can be directly and effectively exhausted, preventing the interior of the liquid heating container from becoming dangerous due to excessive air pressure after boiling water, improving product safety.
[0008] In addition, the lid assembly provided in the above embodiment of the present invention has the following additional technical features.
[0009] In some embodiments, the top lid is fitted over the bottom lid, the inner lid is fully positioned within the bottom lid assembly, and the edges of the top lid and the bottom lid assembly surround and form a steam passageway, or the side walls of the inner lid extend upward and protrude from the bottom lid assembly, so that the top lid can be fitted over the side walls of the inner lid, and the edges of the top lid and the inner lid surround and form a steam passageway, or the side walls of the inner lid extend upward and protrude from the bottom lid assembly, so that the top lid is fitted over the bottom lid assembly, and the top lid, inner lid, and bottom lid assembly surround and form a steam passageway. In fact, the steam passageway is defined by the edges of the top lid and the tops of the bottom lid and / or inner lid, thereby ensuring that the steam flow path does not pass through the center of the top lid.
[0010] In some embodiments, the lower lid assembly comprises a lower lid body having a lid side wall and a lid bottom wall, the lid side wall being disposed around the outer periphery of the lid bottom wall and extending upward, the lower lid body having a flange at the upper part of the lid side wall extending toward the outer periphery, and a sealing ring fitted onto the flange, a portion of the sealing ring being positioned above the flange; the upper lid further comprises an upper lid body and a convex rib, the convex rib being disposed on the underside of the upper lid body, the outer periphery of the upper lid body abutting against the sealing ring, and the convex rib, the upper lid body positioned around the outer periphery of the convex rib, and the sealing ring surrounding and forming a steam passage.
[0011] In these embodiments, the lower lid assembly includes a lower lid body and a sealing ring, and the outer periphery of the upper lid body abuts against the sealing ring, strengthening the seal between the upper lid body and the lower lid body and improving the sealing of the steam passage, thereby preventing a large amount of steam from escaping through the gap between the upper lid body and the lower lid body. This allows steam flowing in through the steam guide passage to flow through the steam passage until it is discharged from the steam outlet, ensuring a controllable and rational discharge path for most of the steam. Specifically, the steam passage is formed by the upper surface of the sealing ring, the convex rib, and the upper lid body positioned around the outer periphery of the convex rib.
[0012] In some embodiments, a grip portion is provided on the top of the upper lid, and the steam passage and steam outlet are located on the outer periphery of the grip portion. The lid assembly includes a lid opening device including a switch portion and an extendable portion. A press hole is provided on the side wall of the grip portion, and the switch portion is installed in the grip portion and corresponds to the press hole. The extendable portion is configured so that both ends of the extendable portion extend and are attached to the container body to secure the lid assembly to the container body. When the switch portion is pressed, both ends of the extendable portion retract, allowing the lid assembly to be separated from the container body.
[0013] In these embodiments, the steam passage and steam outlet are located away from the grip, eliminating the risk of burns to users when lifting the lid assembly with the grip. Furthermore, the lid assembly includes a lid-opening device including a switch and an extendable portion. The extendable portion is in an extended state when free, and pressing the switch retracts both ends of the extendable portion. When the lid assembly is attached to the container body, both ends of the extendable portion extend and attach to the container body, thereby securing the lid assembly to the container body and preventing it from falling. Furthermore, when it is necessary to open the lid assembly, pressing the switch retracts both ends of the extendable portion, separating the lid assembly from the container body and allowing it to be removed. A pressing hole is provided on the side wall of the grip, and the switch is located within the grip and corresponds to the pressing hole. The switch can be directly pressed through the pressing hole, making it convenient not only to operate the device but also to directly remove the lid assembly after pressing the switch to open the lid.
[0014] In some embodiments, the steam guide passage includes a first passage wall and a second passage wall, the first passage wall is located at the outer edge of the inner lid, and the second passage wall is located inside the first passage wall and spaced apart from the first passage wall, thereby forming a steam guide passage between the first passage wall and the second passage wall, and the upper end of the second passage wall is higher than the first passage wall and abuts against the upper lid. With such an arrangement, the top of the second passage located on the inside is higher than the top wall of the first passage located on the outside, thereby forming a steam outlet with an upwardly sloping opening, which increases the area of the steam outlet and makes it easier for steam to discharge and less likely to be blocked. Even if the steam outlet comes into contact with the upper lid, the steam outlet will not be completely blocked, ensuring smooth steam discharge.
[0015] In some embodiments, the plurality of ventilation passages include a plurality of steam inlets installed on the lower lid and a plurality of steam guide pipes connected to the steam inlets, the plurality of steam inlets being configured such that at least one of the plurality of steam inlets is higher than the liquid level in the liquid heating container when the liquid heating container is tilted. First ends of the plurality of steam guide pipes are connected to corresponding ones of the plurality of steam inlets, and second ends of the plurality of steam guide pipes are connected to the steam chamber, and when the liquid heating container is tilted, at least a portion of any one of the plurality of steam guide pipes is higher than the liquid level in the liquid heating container.
[0016] In these embodiments, each ventilation passage includes a steam inlet and a steam guide pipe. The multiple steam inlets are configured so that at least one of the multiple steam inlets is higher than the liquid level in the liquid heating container when the liquid heating container is tilted. This allows steam to be discharged from at least one steam inlet while at least one steam passage remains open after the liquid heating container is tilted, ensuring that steam can flow out of the steam passage. This balances the air pressure inside and outside the pot body, preventing the risk of burns caused by pressurized liquid spraying out and also preventing the risk of excessive pressure buildup in the liquid heating container due to steam not being able to be discharged. Furthermore, when the liquid heating container is tilted, at least a portion of any of the multiple steam guide pipes is higher than the liquid level in the liquid heating container, i.e., no liquid passage is formed in each steam guide pipe. Therefore, after the liquid heating container is tilted, liquid flows into the steam guide pipe from a steam inlet located below the liquid level. However, since at least a portion of each vapor guide tube is higher than the liquid level, the liquid will not flow out of the vapor guide tubes and will not spill out of the lid assembly, causing burns to the user. The container can be tilted freely, achieving the purpose of preventing the lid assembly from tipping over.
[0017] In some embodiments, there are two steam guide tubes, and the two steam guide tubes include a first steam guide tube and a second steam guide tube. There are two steam inlets, and the two steam inlets include a first steam inlet and a second steam inlet, a first end of the first steam guide tube connected to the first steam inlet, a second end of the first steam guide tube extending toward the second steam inlet, and an opening at the second end of the first steam guide tube located within the steam chamber and communicating with the steam chamber. A first end of the second steam guide tube connected to the second steam inlet, a second end of the second steam guide tube extending toward the first steam inlet, and an opening at the second end of the second steam guide tube located within the steam chamber and communicating with the steam chamber.
[0018] In these embodiments, the lid assembly specifically includes a first steam guide pipe, a second steam guide pipe, and a first steam inlet and a second steam inlet. A first end of the first steam guide pipe is connected to the first steam inlet, and a second end thereof extends toward the second steam inlet. Because at least one of the first steam inlet and the second steam inlet is not submerged in water in the tilted liquid heating container, at least one of the first steam inlet and the opening of the first steam guide pipe is not submerged in water in the tilted state, preventing water from flowing out of the lid assembly through the first steam guide pipe. Similarly, a first end of the second steam guide pipe is connected to the second steam inlet, and a second end thereof extends toward the first steam inlet. Because at least one of the second steam inlet and the opening of the second steam guide pipe is not submerged in water in the tilted state, preventing water from flowing out of the lid assembly through the second steam guide pipe.
[0019] In some embodiments, the steam outlet is located on the top lid at a position opposite the water discharge nozzle of the liquid heating container.
[0020] In these embodiments, the steam outlet is located on the upper lid opposite the water nozzle of the liquid heating container, so that the water nozzle and steam outlet are located in a concentrated position, and the user only needs to avoid one position when removing the lid assembly, significantly reducing the risk of burns when removing the lid assembly.
[0021] In some embodiments, the lower lid has a water outlet disposed at an angle on the upper surface of the bottom wall of the lower lid, the water outlet being disposed at the lowest position on the upper surface of the bottom wall of the lower lid.
[0022] In these embodiments, the upper surface of the bottom wall of the lower lid is installed in an inclined structure, and the water outlet is installed at the lowest position on the upper surface of the bottom wall of the lower lid, so that the condensed water in the steam chamber, the first steam guide pipe, and the second steam guide pipe flows from high to low and returns to the water outlet, and then flows back into the container body through the water outlet, which is convenient for recovering the condensed water, reduces water loss, and saves energy.
[0023] According to a second aspect of the present invention, there is provided a liquid heating container comprising a container body having a container opening at an upper portion of the container body, and a lid assembly according to any one of the above technical solutions, the lid assembly being fitted over the container opening.
[0024] The liquid heating container provided in this embodiment includes a lid assembly of any of the above-mentioned technical solutions, and therefore has the beneficial effects of any of the above-mentioned technical solutions, but each of them will not be described here.
[0025] Other aspects and / or advantages of the present invention will be set forth in part in the description that follows, and in part will be obvious from the description, or may be learned by practice of the present general inventive concepts. [Brief explanation of the drawings]

[0036] Lid assemblies and liquid heating containers according to some embodiments of the present invention will now be described with reference to FIGS.
[0037] As shown in Figures 1, 2, 3, 4 and 5, an embodiment of a first aspect of the present invention provides a lid assembly for a liquid heating container. The liquid heating container includes a container body 60, and a lid assembly is fitted over the container body 60. The lid assembly includes a lower lid assembly 10 having a mounting groove 110 with an upward opening, the lower lid assembly 10 having a plurality of ventilation passages, the plurality of ventilation passages communicating with the container body 60, and an inner lid 20 at least partially mounted in the mounting groove 110, the lower lid assembly 10 and the inner lid 20 surrounding and forming a steam chamber 210, the steam chamber 210 communicating with the inner lid 20 and the plurality of ventilation passages communicating with the lower lid assembly 10 and the inner lid 20. The steam chamber 210 is provided with a steam guide passage 220 communicating with the steam passage 310 and the steam chamber 210, and a steam outlet 340 that is installed through the edge of the upper lid 30 and communicates with the steam passage 310. The steam guide passage 220 communicates with the steam passage 310 and the steam chamber 210, and the steam outlet 340 is installed through the edge of the upper lid 30 and communicates with the steam passage 310.
[0038] The lid assembly in this embodiment comprises a lower lid assembly 10, an inner lid 20 and an upper lid 30, with at least a portion of the inner lid 20 attached to the attachment groove 110 of the lower lid assembly 10, and a gap between the bottom wall of the inner lid 20 and the lower lid assembly 10 to form a steam chamber 210 for steam to flow between the inner lid 20 and the lower lid assembly 10. The lower lid assembly 10 has a plurality of vent pipes communicating with the steam chamber 210 and the interior of the container body 60, and steam within the container body 60 can enter the steam chamber 210 through the plurality of vent pipes. Furthermore, the upper lid 30 is fitted over the lower lid assembly 10, the inner lid 20 is completely positioned within the lower lid assembly 10, and the edge of the upper lid 30 and the lower lid assembly 10 surround and form the steam passage 310, or the side walls of the inner lid 20 extend upward and protrude from the lower lid assembly 10, so that the upper lid 30 is fitted over the side walls of the inner lid 20, and the edge of the upper lid 30 and the inner lid 20 surround and form the steam passage 310, or the side walls of the inner lid 20 extend upward and protrude from the lower lid assembly 10. Since the inner lid 20 protrudes from the steam chamber 210, the upper lid 30 is covered by the lower lid assembly 10, and the upper lid 30, inner lid 20, and lower lid assembly 10 surround and form a steam passage 310. The steam guide passage 220 is connected to the steam chamber 210 and the steam passage 310, so that steam in the steam chamber 210 enters the steam passage 310 through the steam guide passage 220 and is finally discharged to the outside through the steam outlet 340 connected to the steam passage 310, thereby achieving normal exhaust function. The steam passage 310 and the steam outlet 340 are located at the edge of the upper lid 30, and the inner lid 20 is installed to separate the upper lid 30 and the middle lid, so that the steam flow path within the lid assembly does not pass through the center of the upper lid 30. Furthermore, the handle 301 for lifting the entire lid assembly is usually located in the center of the upper lid 30, and this structure solves the problem of users being easily burned when lifting the lid assembly with the handle 301. Furthermore, since the steam outlet 340 is installed directly on the edge of the upper cover 30, the steam inside the liquid heating container can be directly and effectively discharged, and the inside of the liquid heating container will not be dangerous due to excessive air pressure after boiling water, thereby improving product safety.
[0039] In some embodiments, the steam guide passage 220 is installed on the inner lid 20. Since the steam chamber 210 is located below the inner lid 20 and the steam passage 310 is located above the inner lid 20, by arranging the steam guide passage 220 on the inner lid 20, the steam chamber 210 and the steam passage 310 can be communicated in the vertical direction, and the steam guide passage 220 can be arranged at an appropriate position.
[0040] As shown in FIGS. 2 and 6 , in some embodiments, the lower lid assembly 10 includes a lower lid body 120 having a lid side wall 121 and a lid bottom wall 122, the lid side wall 121 being disposed around the outer periphery of the lid bottom wall 122 and extending upward, and a flange 123 extending toward the outer periphery of the lid side wall 121 being disposed on the upper part of the lid side wall 121, the lower lid body 120 including a sealing ring 130 fitted onto the flange 123, with a portion of the sealing ring 130 located above the flange 123; and the upper lid 30 further includes an upper lid body 320 and a convex rib 330, the convex rib 330 being disposed on the underside of the upper lid body 320, the outer periphery of which abuts against the sealing ring 130, and the convex rib 330, the upper lid body 320 located around the outer periphery of the convex rib 330, and the sealing ring 130 surrounding the steam passage 310.
[0041] In these embodiments, the lower lid assembly 10 includes a lower lid body 120 and a sealing ring 130. The outer periphery of the upper lid body 320 abuts against the sealing ring 130, thereby strengthening the seal between the upper lid body 320 and the lower lid body 120 and improving the sealing of the steam passage 310. This prevents a large amount of steam from escaping to the outside through the gap between the upper lid body 320 and the lower lid body 120. As a result, steam flowing in through the steam guiding passage 220 can flow within the steam passage 310 until it is discharged from the steam outlet 340, and the discharge path of most of the steam is controllable and rational. Specifically, the steam passage 310 is formed by the upper surface of the sealing ring 130, the convex rib 330, and the upper lid body 320 positioned on the outer periphery of the convex rib 330.
[0042] In another embodiment (not shown), the inner cover 20 comprises an inner cover body and a sealing ring 130. The inner cover body has side walls and a bottom wall. The side walls are installed around the outer periphery of the bottom wall and extend upward, and the upper part of the side walls is provided with a mounting edge extending toward the outer periphery. The sealing ring 130 is fitted onto the mounting edge, with a portion of the sealing ring 130 located above the mounting edge. The upper cover 30 further comprises an upper cover body 320 and a convex rib 330. The convex rib 330 is installed on the underside of the upper cover body 320, and the outer periphery of the upper cover body 320 abuts against the sealing ring 130. The convex rib 330, the upper cover body 320 located around the outer periphery of the convex rib 330, and the sealing ring 130 surround the steam passage 310.
[0043] In these embodiments, the inner cover 20 includes an inner cover body and a sealing ring 130. The outer periphery of the upper cover body 320 abuts against the sealing ring 130, strengthening the seal between the upper cover body 320 and the inner cover body and improving the sealing of the steam passage 310. This prevents a large amount of steam from escaping to the outside through the gap between the upper cover body 320 and the inner cover body. As a result, steam flowing in through the steam guiding passage 220 can flow within the steam passage 310 until it is discharged from the steam outlet 340, and the discharge path of most of the steam is controllable and rational. Specifically, the steam passage 310 is formed by the upper surface of the sealing ring 130, the convex rib 330, and the upper cover body 320 positioned on the outer periphery of the convex rib 330.
[0044] 1, 6, and 7, a grip portion 301 is provided on the top of the upper lid 30, and the steam passage 310 and the steam outlet 340 are located on the outer periphery of the grip portion 301. The lid assembly is provided with a lid opening device 50. The lid opening device 50 includes a switch portion and an extendable portion, and a pressing hole is provided on the side wall of the grip portion 301. The switch portion is installed within the grip portion 301 and corresponds to the pressing hole, and the extendable portion is configured so that both ends of the extendable portion can be extended and attached to the container body 60 to secure the lid assembly to the container body 60, and further, when the switch portion is pressed, both ends of the extendable portion retract, allowing the lid assembly to be separated from the container body 60.
[0045] In these embodiments, the steam passage 310 and the steam outlet 340 are positioned away from the grip portion 301, thereby solving the problem of a user being easily burned when lifting the lid assembly with the grip portion 301. Furthermore, the lid assembly includes a lid opening device 50, which includes a switch unit and an extendable unit. The extendable unit is in an extended state in a free state, and both ends of the extendable unit are retracted by pressing the switch unit. When the lid assembly is attached to the container body 60, both ends of the extendable unit are extended and attached to the container body 60, thereby fixing the lid assembly to the container body 60 and preventing the lid assembly from falling. Furthermore, when it is necessary to open the lid assembly, the switch unit is pressed, and both ends of the extendable unit are retracted, separating the lid assembly from the container body 60 and allowing the lid assembly to be removed. In addition, a press hole is provided on the side wall of the grip portion 301, and the switch unit is disposed within the grip portion 301 and corresponds to the press hole. Since the switch part can be directly pressed through the pressing hole, not only is the operation convenient, but it is also convenient to directly remove the cover assembly after pressing the switch part to open the cover.
[0046] 4, 5, 6, and 7, the steam guide passage 220 is disposed on the outer peripheral edge of the inner lid 20 and extends in the vertical direction. A steam inlet is provided at the lower end of the steam guide passage 220, and a steam outlet is provided at the upper end of the steam guide passage 220.
[0047] In these embodiments, the steam guide passage 220 is installed on the outer peripheral edge of the inner lid 20, extends vertically, and has a steam inlet at the lower end of the steam guide passage 220 and a steam outlet at the upper end of the steam guide passage 220. Therefore, the steam guide passage 220 can be directly connected from the steam chamber 210 to the steam passage 310 located on the edge of the upper lid 30, and the steam guide passage 220 is short, which is advantageous for the flow of steam.
[0048] Furthermore, in some embodiments, as shown in Figures 4, 5, 6 and 7, the steam guide passage 220 includes a first passage wall 221 and a second passage wall 222, the first passage wall 221 is located at the outer edge of the inner lid 20, and the second passage wall 222 is located inside the first passage wall 221 and spaced apart from the first passage wall 221, thereby forming the steam guide passage 220 between the first passage wall 221 and the second passage wall 222, the upper end of the second passage wall 222 is higher than the first passage wall 221, and the second passage wall 222 abuts against the upper lid 30. With such an arrangement, the top of the second passage located on the inside is higher than the top wall of the first passage located on the outside, whereby the steam outlet is formed with an opening that slopes upward, and the area of the steam outlet is increased, making it easier for steam to be discharged and less likely to be blocked; even if the steam outlet comes into contact with the upper lid 30, the steam outlet will not be completely blocked, ensuring smooth discharge of steam.
[0049] 8 and 9, in some embodiments, a first engagement portion 1211 is provided on one of the side wall and lid side wall 121 of the top lid 30, and a first engagement hole 3301 is provided on the other. The first engagement portion 1211 is fitted into the first engagement hole 3301, and the top lid 30 is fitted and connected to the lower lid. A second engagement portion 1212 is provided on one of the side wall and lid side wall 121 of the inner lid 20, and a second engagement hole 230 is provided on the other. The second engagement portion 1212 is fitted into the second engagement hole 230, and the inner lid 20 is fitted and connected to the lower lid. In this way, the upper cover 30 is connected to the lower cover by mating the first engaging portion 1211 with the first engaging hole 3301, and the inner cover 20 is attached to the mounting groove 110 of the lower cover by mating the second engaging portion 1212 with the second engaging hole 230. The mating connection has advantages such as stable connection and convenient installation. Furthermore, the first engaging portion 1211, the first engaging hole 3301, the second engaging portion 1212, and the second engaging hole 230 have a simple structure, are easy to process and manufacture, and have low manufacturing costs. For example, in actual assembly, first, the inner lid 20 and the lower lid are assembled, the second engaging portion 1212 is aligned with the second engaging hole 230, and the inner lid 20 is pushed downward to assemble the inner lid 20 and the lower lid, and then the upper lid 30 and the lower lid are assembled, the first engaging portion 1211 is aligned with the first engaging hole 3301, and the upper lid 30 is simply pushed downward to complete the assembly of the upper lid 30 and the lower lid. This simplifies the assembly process.
[0050] 2, 6, 7, 8, and 9, the multiple ventilation passages include multiple steam inlets installed on the lower lid and multiple steam guide tubes connected to the steam inlets, and the multiple steam inlets are configured such that at least one of the multiple steam inlets is higher than the liquid level in the liquid heating container when the liquid heating container is tilted. First ends of the multiple steam guide tubes are connected to the multiple steam inlets, respectively, and second ends of the multiple steam guide tubes are connected to the steam chamber 210, and when the liquid heating container is tilted, at least a portion of any one of the multiple steam guide tubes is higher than the liquid level in the liquid heating container.
[0051] In these embodiments, each ventilation passage includes a steam inlet and a steam guide pipe. The multiple steam inlets are configured so that at least one of the multiple steam inlets is higher than the liquid level in the liquid heating container when the liquid heating container is tilted. This allows steam to be discharged from at least one steam inlet while at least one steam passage remains open after the liquid heating container is tilted, ensuring that steam can flow out of the steam passage. This balances the air pressure inside and outside the pot body, preventing the risk of burns caused by pressurized liquid spraying out and also preventing the risk of excessive pressure buildup in the liquid heating container. Furthermore, when the liquid heating container is tilted, at least a portion of any of the multiple steam guide pipes is higher than the liquid level in the liquid heating container, i.e., no liquid passage is formed in each steam guide pipe. Therefore, after the liquid heating container is tilted, liquid flows into the steam guide pipe from a steam inlet located below the liquid level. However, since at least a portion of each vapor guide tube is higher than the liquid level, the liquid will not flow out of the vapor guide tube and will not overflow from the lid assembly, causing burns to the user. The container can be tilted freely, achieving the purpose of preventing the lid assembly from tipping over.
[0052] 2 , 6 , 7 , 8 , and 9 , there are two steam guide pipes, and the two steam guide pipes include a first steam guide pipe 401 and a second steam guide pipe 402. There are two steam inlets, and the two steam inlets include a first steam inlet 140 and a second steam inlet 150. A first end of the first steam guide pipe 401 is connected to the first steam inlet 140, a second end of the first steam guide pipe 401 extends toward the second steam inlet 150, and an opening at the second end of the first steam guide pipe 401 is located within the steam chamber 210 and is connected to the steam chamber 210. A first end of the second steam guide pipe 402 is connected to the second steam inlet 150, a second end of the second steam guide pipe 402 extends toward the first steam inlet 140, and an opening at the second end of the second steam guide pipe 402 is located within the steam chamber 210 and is connected to the steam chamber 210.
[0053] In these embodiments, specifically, the lid assembly includes a first steam guide pipe 401, a second steam guide pipe 402, a first steam inlet 140, and a second steam inlet 150. A first end of the first steam guide pipe 401 is connected to the first steam inlet 140, and a second end thereof extends toward the second steam inlet 150. At least one of the first steam inlet 140 and the second steam inlet 150 is not submerged in water in the tilted liquid heating container, and therefore, in the tilted state, at least one of the first steam inlet 140 and the opening of the first steam guide pipe 401 is not submerged in water, preventing water from flowing out of the lid assembly through the first steam guide pipe 401. Similarly, since the first end of the second steam guide pipe 402 is connected to the second steam inlet 150 and the second end extends toward the first steam inlet 140, in the tilted state, at least one of the second steam inlet 150 and the opening of the second steam guide pipe 402 is not submerged in water, preventing water from flowing out of the lid assembly through the second steam guide pipe 402.
[0054] In some embodiments, as shown in FIG. 10, the steam outlet 340 is installed on the upper lid 30 at a position opposite the water discharge nozzle 620 of the liquid heating container.
[0055] In these embodiments, the steam outlet 340 is installed on the upper lid 30 at a position opposite the water discharge nozzle 620 of the liquid heating container, so that the water discharge nozzle 620 and the steam outlet 340 are concentrated in one location, and the user only needs to avoid one location when removing the lid assembly, significantly reducing the risk of burns when removing the lid assembly.
[0056] In some embodiments, as shown in FIG. 9, the tank has a water outlet 160 that is installed at an angle on the upper surface of the bottom wall of the lower lid, and the water outlet 160 is installed at the lowest position on the upper surface of the bottom wall of the lower lid.
[0057] The upper surface of the bottom wall of the lower lid is installed in an inclined structure, and the water outlet 160 is installed at the lowest position on the upper surface of the bottom wall of the lower lid, so that the condensed water in the steam chamber 210, the first steam guide pipe 401, and the second steam guide pipe 402 flows from high to low and returns to the water outlet 160, and then flows back into the container body 60 through the water outlet 160, which makes it easy to recover the condensed water, reduces water loss, and saves energy.
