Mode for Carrying Out the Invention
[0019] In this specification, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings refer to the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments that conform to the present invention. Rather, they are merely examples of devices, systems, facilities, and methods that conform to aspects of the present invention.
[0020] Hereinafter, a lid assembly and a liquid heating container according to embodiments of the present invention will be described with reference to FIGS. 1 to 30.
[0021] FIG. 1 shows the lid assembly 1 according to an embodiment of the present invention being inverted as a whole. The lid assembly is generally used to cover a liquid heating container such as an electric kettle, and has an anti-tipping structure inside to prevent water from entering. Since the structure does not include a steel ball for closing the exhaust line, there is no abnormal noise, the number of parts is small, the assembly is simple, and the cost is low. The lid assembly is a lower lid 30 in which at least two openings are provided. The at least two openings are configured such that when the liquid heating container is in a tipped state, at least one of the at least two openings is located above the liquid level in the liquid heating container. The lower lid 30 is a middle lid 20 located above the lower lid 30 and connected to the lower lid 30. The middle lid 20 and the lower lid 30 form an accommodation chamber. An insert 40 is installed in the accommodation chamber and connected to the middle lid 20 and the lower lid 30. The insert 40 and the middle lid 20 form an upper steam chamber, and the insert 40 and the lower lid 30 form a lower steam chamber communicating with the upper steam chamber. At least two openings of the lower lid 30 communicate with the lower steam chamber 48. The insert 40 includes an internal chamber steam outlet 45 communicating with the upper steam chamber 44 and a lid steam outlet 25 communicating with the internal chamber steam outlet 45. The upper steam chamber 44 and the lower steam chamber 48 form an internal chamber 34. The space outside the internal chamber in the accommodation chamber forms an external chamber 36. The internal chamber communicates with the external chamber 36 through the internal chamber steam outlet 45. The external chamber 36 communicates with the lid steam outlet 25. When the lid assembly covers the liquid heating container, the lid steam outlet 25 communicates with the handle steam passage 82 of the liquid heating container. The lid assembly having the above-described structure can satisfy the normal exhaust requirements of the liquid heating container provided with the lid assembly, and can also prevent the liquid from splashing and causing injury to the user when the liquid heating container is accidentally tipped over, thereby improving the safety of use.Specifically, as shown in FIG. 5, when the liquid heating container including the above-described lid assembly is erected to heat the liquid therein, the vapor in the container body 8 flows into the lower vapor chamber 48 through at least two openings of the lower lid 30, and then flows into the upper vapor chamber 44 communicating with the lower vapor chamber 48. Thereafter, it is discharged through the internal chamber vapor outlet 45 and the lid vapor outlet 25, and flows to the bottom lid 83 through, for example, the handle vapor passage 82 provided in the handle 81 to be condensed, or is discharged to the outside of the container body 8. As shown in FIG. 19, when the liquid heating container is overturned (usually to the left or right side), the liquid enters the lower vapor chamber from the opening of the lower lid 30 located below the liquid level 9. However, since at least one opening of the lower lid 30 is located above the liquid level 9, the openness of the vapor passage starting from at least one opening can be maintained, and the vapor can be discharged smoothly. Thereby, it is possible to effectively prevent the high-temperature liquid in the container from ejecting under the action of a greater pressure, and avoid the danger caused by the non-discharge of the vapor in the liquid heating container or excessive pressure. Further, by providing the internal chamber and the external chamber, more vapor can be condensed into the liquid and returned to the container, so that the discharge of the vapor is reduced or eliminated, the loss of the liquid is reduced, and the energy can be saved.
[0022] FIG. 2 is an exploded view showing a lid assembly of a liquid heating container according to the first embodiment of the present application. In this embodiment, the lid assembly 1 seals and covers the upper opening of the container body 8 of the liquid heating container, and includes other standard components such as an upper lid 10, a middle lid 20, a lower lid 30, a lid lock 50, a lid spring 60, and a water injection button assembly 70. The upper lid 10 is installed on the middle lid 20 and can shield the components of the middle lid 20, which is advantageous for the cleanliness and appearance of the lid assembly. The middle lid 20 is installed between the upper lid 10 and the lower lid 30. The middle lid 20 and the lower lid 30 surround and form a storage chamber, and an insert 40 connected to the middle lid 20 and the lower lid 30 is provided in the storage chamber. The insert 40 and the middle lid 20 surround and form an upper steam chamber, the insert 40 and the lower lid 30 surround and form a lower steam chamber communicating with the upper steam chamber, and an internal chamber steam outlet 45 communicating with the upper steam chamber 44 is provided. As shown in FIGS. 1 and 3, the lid assembly 1 further includes a lid steam outlet 25 communicating with the internal chamber steam outlet 45. The lid steam outlet 25 is provided in the middle lid 20 or the lower lid 30, or is formed surrounded by the middle lid 20 and the lower lid 30. The positions of the internal chamber steam outlet 45 and the lid steam outlet 25 are set such that when the lid assembly 1 covers the container body 8 of the liquid heating container, the internal chamber steam outlet 45 and the lid steam outlet 25 are adjacent to the handle 81 and communicate with the inlet of the handle steam passage 82.
[0023] As shown in FIG. 4, the insert 40 includes a partition 401 that separates the upper steam chamber 44 and the lower steam chamber 48. A partition rib 47 extending downward is provided on the lower surface of the partition 401. The partition rib 47 is connected to the lower lid 30 and partitions the lower steam chamber into a lower left steam chamber 48L and a lower right steam chamber 48R. When the lid assembly 1 covers the liquid heating container, the lower left steam chamber 48L and the lower right steam chamber 48R are respectively located on the left side and the right side of the neutral plane of the liquid heating container. As shown in FIGS. 2 and 12, the partition 401 is adjacent to the internal chamber steam outlet 45 and is disposed on the left side and the right side of the internal chamber steam outlet 45 respectively, and includes a right upper steam chamber inlet hole 41R and a left upper steam chamber inlet hole 41L that are offset in the front-rear direction. A protruding rib extending upward is provided on the upper surface of the partition 401. The protruding rib includes a left protruding rib 49L and a right protruding rib 49R. The left protruding rib 49L extends substantially along the extension direction of the rear wall 403 and the left side wall 404 of the insert 40 from near the right upper steam chamber inlet hole 41R to near the front wall 402 of the insert 40. Thereby, the upper steam chamber is partitioned into a left upper first steam passage 42L located outside the left protruding rib 49L and a left upper second steam passage 44L located inside the left protruding rib 49L. The left upper first steam passage 42L and the left upper second steam passage 44L communicate with each other. The right protruding rib 49R extends substantially along the extension direction of the rear wall 403 and the right side wall 405 of the insert 40 from near the left upper steam chamber inlet hole 41L to near the front wall of the insert 40. Thereby, the upper steam chamber is partitioned into a right upper first steam passage 42R located outside the right protruding rib 49R and a right upper second steam passage 44R located inside the right protruding rib 49R. The right upper first steam passage 42R and the right upper second steam passage 44R communicate with each other. The left upper first steam passage 42L and the right upper first steam passage 42R communicate with the right upper steam chamber inlet hole 41R and the left upper steam chamber inlet hole 41L respectively. The left upper second steam passage 44L and the right upper second steam passage 44R both communicate with the internal chamber steam outlet 45. By arranging the insert 40 with such a structure, a two-layer labyrinth steam passage structure is realized with a small number of parts, and the assembly cost is reduced.In this embodiment, the insert 40 is installed between the middle cover 20 and the lower cover 30. Specifically, screw posts 46 are provided in the partition 401 of the insert 40, and corresponding screw posts 37 are provided at the corresponding positions on the lower cover 30. During installation, the screw post 37 penetrates the screw post hole 46 and inserts the partition rib 47 on the lower surface of the insert 40 into the partition rib groove 35 of the lower cover 30 (Figs. 2 and 4), and the left protruding rib 49L and the right protruding rib 49R are respectively inserted into the left protruding rib groove 29L and the right protruding rib groove 29R on the lower surface of the middle cover 20 (Fig. 3). Finally, the lower cover 30 and the insert 40 are fixed to the middle cover 20 by screws provided on the screw post 37. It should be understood that the above installation method is merely an example, and the insert 40 can also be installed between the middle cover 20 and the lower cover 30 by other appropriate methods. Furthermore, the insert 40 can also be integrally formed with the middle cover 20 or the lower cover 30, which can further reduce the number of parts and reduce the assembly cost.
[0024] As shown in FIGS. 1 and 2, in the present embodiment, the lower lid 30 is provided with four openings: a left front opening 32L, a right front opening 32R, a left rear opening 31L, and a right rear opening 31R. The left front opening 32L and the left rear opening 31L communicate with the left lower steam chamber 48L, and the right front opening 32R and the right rear opening 31R communicate with the right lower steam chamber 48R. When the liquid heating container is in a toppled state (FIG. 19), at least the left front opening 32L or the right front opening 32R is configured to be located above the liquid level 9 of the liquid heating container. Ideally, the two openings on one side (i.e., the left front opening 32L and the left rear opening 31L, or the right front opening 32R and the right rear opening 31R) are located above the liquid level 9 in the liquid heating container. Therefore, the steam is discharged from the opening located above the liquid level 9 through the left lower steam chamber / right lower steam chamber, the right upper steam chamber / left upper steam chamber, the internal chamber steam outlet 45, and the lid steam outlet 25, serving the functions of explosion prevention and pressure relief. When the liquid heating container is in a normal state of filling with water (FIG. 18), at least the left rear opening 31L or the right rear opening 31R is located above the liquid level 9 in the liquid heating container, whereby the steam can be discharged from the opening located above the liquid level 9 through the left lower steam chamber and / or the right lower steam chamber, the right upper steam chamber and / or the left upper steam chamber, the internal chamber steam outlet 45, and the lid steam outlet 25.
[0025] Next, with reference to FIGS. 7, 8, 12, and 15, the steam passage in the lid assembly 1 of the embodiment shown in FIG. 2 will be described. When all of the left front opening 32L, right front opening 32R, left rear opening 31L, and right rear opening 31R of the lower lid 30 are above the liquid level (for example, when the liquid heating container is upright and the liquid heating container is in the heating operation state), the steam in the container body 8 enters the lower left steam chamber 48L through the left front opening 32L and the left rear opening 31L, and enters the lower right steam chamber 48R through the right front opening 32R and the right rear opening 31R. Then, the steam that has entered the lower left steam chamber 48L enters the upper right first steam passage 42R through the upper left steam chamber inlet hole 41L of the partition 401, and enters the upper right second steam passage 44R through the upper right steam chamber groove 43R (that is, the gap between the right protruding rib 49R and the front wall 402 of the insert 40). The steam that has entered the lower right steam chamber 48R enters the upper left first steam passage 42L through the upper right steam chamber inlet hole 41R of the partition 401, and enters the upper left second steam passage 44L through the upper left steam chamber groove 43L (that is, the gap between the left protruding rib 49L and the front wall 402 of the insert 40). The two steams that have reached the upper left second steam passage 44L and the upper right second steam passage 44R merge and are discharged from the internal chamber steam outlet 45 to the external chamber, flow through the handle steam passage 82 installed in the handle 81 through the lid steam outlet 25, are condensed on the bottom lid 83, or are discharged to the outside of the container body 8. When the liquid heating container is in the normal state of pouring water (FIG. 18), the liquid enters the left front opening 32L and the right front opening 32R of the lower lid 30, and the left rear opening 31L and the right rear opening 31R are located above the liquid level 9, whereby the steam in the container body 8 enters the lower left steam chamber 48L through the left rear opening 31L, flows into the lower right steam chamber 48R through the right rear opening 31R, and then is discharged according to the above passage.After the liquid heating container is toppled, for example, after it is toppled to the right (FIG. 19), the liquid enters the right front opening 32R and the right rear opening 31R of the lower lid 30, and the left front opening 32L and the left rear opening 31L are located above the liquid level 9. As a result, the vapor in the container body 8 enters the left lower vapor chamber 48L through the left front opening 32L and the left rear opening 31L, then flows into the right lower vapor chamber 48R through the right rear opening 31R, and then enters the upper right first vapor passage 42R through the upper left vapor chamber inlet hole 41L of the partition 401, and enters the upper right second vapor passage 44R through the upper right vapor chamber groove 43R (that is, the gap between the right protruding rib 49R and the front wall 402 of the insert 40), and is further discharged to the external chamber through the internal chamber vapor outlet 45, and enters the handle vapor passage 82 in the handle 81 through the lid vapor outlet 25. As can be seen from the above description, the lid assembly according to the present embodiment has upper and lower two-layer vapor chambers, and the upper vapor chamber has a labyrinth vapor passage, so the flow path of the vapor becomes longer, preventing the condensation of the vapor, reducing the loss of the liquid, having the function of saving energy, and also being able to prevent the liquid from flowing out from the vapor passage and the lid vapor outlet after the liquid heating container is discarded.
[0026] In addition, in the present embodiment, the left front opening 32L and the right front opening 32R of the lower lid 30 are arranged such that when the lid assembly covers the liquid heating container, the condensate in the left lower vapor chamber 48L and the right lower vapor chamber 48R automatically flows into the left front opening 32L and the right front opening 32R respectively, and / or the left rear opening 31L and the right rear opening 31R are arranged such that when the lid assembly covers the liquid heating container, the condensate in the left lower vapor chamber 48L and the right lower vapor chamber 48R automatically flows into the left rear opening 31L and the right rear opening 31R respectively. FIG. 17 shows the flow direction of the condensate according to one aspect. In this aspect, when the lid assembly 1 normally covers the liquid heating container, the left front opening 32L and the right front opening 32R of the lower lid 30 are at the lowest positions. For example, this can be achieved by providing an inclination on the bottom wall of the lower lid 30. In this way, the condensate in the vapor passage can automatically return to the container, facilitating the recovery of the condensate, reducing the loss of the liquid, and saving energy.
[0027] FIG. 20 is an exploded view showing a liquid heating container including a lid assembly according to a second embodiment of the present application. The main differences between this embodiment and the first embodiment are the specific structure of the insert 40, the structure of the steam passage, and the flow path of the steam. Hereinafter, only the differences between this embodiment and the first embodiment will be described. Unless otherwise specified, the above description regarding the first embodiment is also applicable to the second embodiment. As shown in FIGS. 20 to 23 and FIG. 25, in this embodiment, the partition 401 of the insert 40 includes a front wall 402 and a rear wall 403 adjacent to the insert 40, and a right upper steam chamber inlet hole 41R and a left upper steam chamber inlet hole 41L arranged diagonally. On the upper surface of the partition 401, protruding ribs extending upward are provided. The protruding ribs include a left protruding rib 49L and a right protruding rib 49R. The left protruding rib 49L is located between the left upper steam chamber inlet hole 41L and the internal chamber steam outlet 45, extends forward from the rear wall 403 of the insert 40 and approaches the front wall 402 of the insert 40. Thereby, the upper steam chamber is partitioned into a left upper first steam passage 42L located outside the left protruding rib 49L and a left upper second steam passage 44L located inside the left protruding rib 49L. The left upper first steam passage 42L and the left upper second steam passage 44L communicate with each other. The right protruding rib 49R extends rearward from the front wall 402 of the insert 40 and approaches the rear wall 403 of the insert 40. Thereby, the upper steam chamber is partitioned into a right upper first steam passage 42R located outside the right protruding rib 49R and a right upper second steam passage 44R located inside the right protruding rib 49R. The right upper first steam passage 42R and the right upper second steam passage 44R communicate with each other. The left upper first steam passage 42L and the right upper first steam passage 42R communicate with the left upper steam chamber inlet hole 41L and the right upper steam chamber inlet hole 41R respectively. The left upper second steam passage 44L and the right upper first steam passage 42R both communicate with the internal chamber steam outlet 45.
[0028] Next, referring to FIGS. 23 and 25, the steam passage in the lid assembly 1 of the second embodiment shown in FIG. 20 will be described. When the left front opening 32L, the right front opening 32R, the left rear opening 31L, and the right rear opening 31R of the lower lid 30 are all above the liquid level (for example, when the liquid heating container is upright and the liquid heating container is in the heating operation state), the steam in the container body 8 enters the lower left steam chamber 48L through the left front opening 32L and the left rear opening 31L, and enters the lower right steam chamber 48R through the right front opening 32R and the right rear opening 31R. Then, the steam that enters the lower left steam chamber 48L enters the upper left first steam passage 42L through the upper left steam chamber inlet hole 41L of the partition 401, enters the upper left second steam passage 44L through the upper left steam chamber groove 43L (that is, the gap between the left protruding rib 49L and the front wall 402 of the insert 40), and then is discharged from the internal chamber steam outlet 45 to the external chamber, flows through the handle steam passage 82 installed in the handle 81 through the lid steam outlet 25, is condensed on the bottom lid 83, or is discharged to the outside of the container body 8. On the other hand, the steam that enters the lower right steam chamber 48R enters the upper right first steam passage 42R through the upper right steam chamber inlet hole 41R of the partition 401, and is discharged to the external chamber through the upper right steam chamber groove 43R (that is, the gap between the right protruding rib 49R and the front wall 402 of the insert 40) and the internal chamber steam outlet 45. When the liquid heating container is in the state of normally pouring water (FIG. 18), the left front opening 32L and the right front opening 32R of the lower lid 30 enter the liquid, but the left rear opening 31L and the right rear opening 31R are held above the liquid level 9, whereby the steam in the container body 8 can flow into the lower left steam chamber 48L from the left rear opening 31L and into the lower right steam chamber 48R from the right rear opening 31R, and then is discharged according to the above passage.After the liquid heating container has fallen over, for example, after falling over to the right (FIG. 19), the liquid enters the right front opening 32R and the right rear opening 31R of the lower lid 30, and the left front opening 32L and the left rear opening 31L are located above the liquid level 9. As a result, the vapor in the container body 8 enters the left lower vapor chamber 48L through the left front opening 32L and the left rear opening 31L, and then enters the upper left first vapor passage 42L through the upper left vapor chamber inlet hole 41L of the partition 401, and enters the upper left second vapor passage 44L through the upper left vapor chamber groove 43L (that is, the gap between the left protruding rib 49L and the front wall 402 of the insert 40), and is discharged to the external chamber through the internal chamber vapor outlet 45. In the present embodiment, although the positions of the upper left vapor chamber inlet hole 41L and the upper right vapor chamber inlet hole 41R, and the specific structure and arrangement of the ribs are different from those of the first embodiment, similarly, the lid assembly has upper and lower two-layer vapor chambers, and the upper vapor chamber has a labyrinth vapor passage, the flow path of the vapor becomes longer, which is advantageous for liquid recovery.
[0029] FIG. 24 shows a modification of the second embodiment. In this modification, the upper left steam chamber inlet holes 41L and upper right steam chamber inlet holes 41R, as well as the left protruding ribs 49L and right protruding ribs 49R, are substantially symmetric with respect to the neutral plane of the liquid heating container. Specifically, the partition 401 of the insert 40 includes the upper right steam chamber inlet hole 41R and the upper left steam chamber inlet hole 41L, which are adjacent to the rear wall 403 of the insert 40 and arranged symmetrically in the left-right direction. The protruding ribs include the left protruding rib 49L and the right protruding rib 49R, which are arranged symmetrically in the left-right direction. The left protruding rib 49L and the right protruding rib 49R extend forward from the rear wall 403 of the insert 40 and approach the front wall 402 of the insert 40. As a result, the upper steam chamber is partitioned into an upper left first steam passage 42L located outside the left protruding rib 49L, an upper left second steam passage 44L located inside the left protruding rib 49L, an upper right first steam passage 42R located outside the right protruding rib 49R, and an upper right second steam passage 44R located inside the right protruding rib 49R. The upper left first steam passage 42L and the upper left second steam passage 44L communicate with each other, the upper right first steam passage 42R and the upper right second steam passage 44R communicate with each other, the upper left first steam passage 42L and the upper right first steam passage 42R communicate with the upper left steam chamber inlet hole 41L and the upper right steam chamber inlet hole 41R respectively, and the upper left second steam passage 44L and the upper right first steam passage 42R both communicate with the internal chamber steam outlet 45.
[0030] Next, the vapor flow path in the lid assembly 1 according to this modification will be described with reference to FIG. 24. When all of the left front opening 32L, the right front opening 32R, the left rear opening 31L, and the right rear opening 31R of the lower lid 30 are above the liquid level (for example, when the liquid heating container is upright and the liquid heating container is in the heating operation state), the vapor in the container body 8 enters the lower left vapor chamber 48L through the left front opening 32L and the left rear opening 31L, and enters the lower right vapor chamber 48R through the right front opening 32R and the right rear opening 31R. Then, the vapor that has entered the lower left vapor chamber 48L enters the upper left first vapor passage 42L through the upper left vapor chamber inlet hole 41L of the partition 401, enters the upper left second vapor passage 44L through the upper left vapor chamber groove 43L (that is, the gap between the left protruding rib 49L and the front wall 402 of the insert 40), and then is discharged from the internal chamber vapor outlet 45 to the external chamber, flows through the handle vapor passage 82 installed in the handle 81 through the lid vapor outlet 25, flows to the bottom lid 83 and is condensed, or is discharged to the outside of the container body 8. On the other hand, the vapor that has entered the lower right vapor chamber 48R enters the upper right first vapor passage 42R through the upper right vapor chamber inlet hole 41R of the partition 401, enters the upper right second vapor passage 44R through the upper right vapor chamber groove 43R (that is, the gap between the right protruding rib 49R and the front wall 402 of the insert 40), and further is discharged from the internal chamber vapor outlet 45 to the external chamber, enters the handle vapor passage 82 in the handle 81 through the lid vapor outlet 25, flows into the handle vapor passage 82 installed in the handle 81, flows to the bottom lid 83 and is condensed, or is discharged to the outside of the container body 8. When the liquid heating container is in the state of normally pouring water (FIG. 18), the left front opening 32L and the right front opening 32R of the lower lid 30 enter the liquid, but the left rear opening 31L and the right rear opening 31R are held above the liquid level 9, whereby the vapor in the container body 8 can flow into the lower left vapor chamber 48L from the left rear opening 31L and into the lower right vapor chamber 48R from the right rear opening 31R, and then is discharged according to the above-described passage.After the liquid heating container has fallen over, for example, after falling to the right (Fig. 19), the liquid enters the right front opening 32R and the right rear opening 31R of the lower lid 30, and the left front opening 32L and the left rear opening 31L are located above the liquid level 9. As a result, the vapor in the container body 8 enters the left lower vapor chamber 48L through the left front opening 32L and the left rear opening 31L, and then enters the upper left first vapor passage 42L through the upper left vapor chamber inlet hole 41L of the partition 401. It enters the upper left second vapor passage 44L through the upper left vapor chamber groove 43L (that is, the gap between the left protruding rib 49L and the front wall 402 of the insert 40), and then is discharged to the external chamber through the internal chamber vapor outlet 45. In this modification, both the upper left vapor chamber inlet hole 41L and the upper right vapor chamber inlet hole 41R are arranged in the vicinity of the rear wall 403, and both the upper left vapor chamber groove 43L and the upper right vapor chamber groove 43R are arranged in the vicinity of the rear wall 403. Therefore, the vapor flow paths of the left and right upper vapor chambers become longer, and the recovery of the liquid becomes easier.
[0031] FIG. 26 shows an exploded view of the lid assembly according to the third embodiment of the present application. The main differences between this embodiment and the first embodiment are the specific structure of the insert 40, the structure of the steam passage, and the flow path of the steam. Hereinafter, only the differences between this embodiment and the first embodiment will be described. Unless otherwise specified, the above description regarding the first embodiment is also applicable to the third embodiment. As shown in FIGS. 26 to 30, in this embodiment, the partition 401 of the insert 40 is adjacent to the rear wall 403 of the insert 40 and includes a left upper steam chamber inlet hole 41L and a right upper steam chamber inlet hole 41R that are respectively disposed on the left side and the right side of the internal chamber steam outlet 45. The protruding ribs include a left protruding rib 49L and a right protruding rib 49R. The left protruding rib 49L is located between the left upper steam chamber inlet hole 41L and the internal chamber steam outlet 45 and extends along the extension direction of the left side wall 404 and the front wall 402 of the insert 40 from the rear wall 403 of the insert 40 until it approaches the right side wall 405 of the insert 40. The right protruding rib 49R is located between the right upper steam chamber inlet hole 41R and the internal chamber steam outlet 45 and extends along the extension direction of the right side wall 405 and the front wall 402 of the insert 40 from the rear wall of the insert 40 until it approaches the left protruding rib 49L. Thereby, the upper steam chamber is partitioned into a left upper first steam passage 42L located outside the left protruding rib 49L, a right upper first steam passage 42R located outside the right protruding rib 49R, and an intermediate steam passage 44 located between the left protruding rib 49L and the right protruding rib 49R. The left upper first steam passage 42L, the right upper first steam passage 42R, and the intermediate steam passage 44 communicate with each other. The left upper first steam passage 42L and the right upper first steam passage 42R communicate with the left upper steam chamber inlet hole 41L and the right upper steam chamber inlet hole 41R respectively. The intermediate steam passage 44 communicates with the internal chamber steam outlet 45.
[0032] Next, referring to FIGS. 28 to 29, the steam passage in the lid assembly 1 of the third embodiment shown in FIG. 26 will be described. When all of the left front opening 32L, the right front opening 32R, the left rear opening 31L, and the right rear opening 31R of the lower lid 30 are above the liquid level (for example, when the liquid heating container is upright and the liquid heating container is in the heating operation state), the steam in the container body 8 enters the lower left steam chamber 48L through the left front opening 32L and the left rear opening 31L, and enters the lower right steam chamber 48R through the right front opening 32R and the right rear opening 31R. Then, the steam that has entered the lower left steam chamber 48L enters the upper left first steam passage 42L through the upper left steam chamber inlet hole 41L of the partition 401, and the steam that has entered the lower right steam chamber 48R enters the upper right first steam passage 42R through the upper right steam chamber inlet hole 41R of the partition 401. The two steam flows from the upper left first steam passage 42L and the upper right first steam passage 42R merge and enter the intermediate steam passage 44. Then, it is discharged to the external chamber through the internal chamber steam outlet 45, enters the handle steam passage 82 in the handle 81 through the lid steam outlet 25, flows into the handle steam passage 82 installed in the handle 81, flows to the bottom lid 83 and is condensed, or is discharged to the outside of the container body 8. When the liquid heating container is in the state of normally pouring water (FIG. 18), the left front opening 32L and the right front opening 32R of the lower lid 30 enter the liquid, but the left rear opening 31L and the right rear opening 31R are held above the liquid level 9, whereby the steam in the container body 8 can flow into the lower left steam chamber 48L from the left rear opening 31L and into the lower right steam chamber 48R from the right rear opening 31R, and then is discharged according to the above passage. After the liquid heating container is overturned, for example, after being overturned to the right (FIG. 19), the liquid enters the right front opening 32R and the right rear opening 31R of the lower lid 30, and the left front opening 32L and the left rear opening 31L are located above the liquid level 9, whereby the steam in the container body 8 enters the lower left steam chamber 48L through the left front opening 32L and the left rear opening 31L, and then sequentially enters the upper left first steam passage 42L and the intermediate steam passage 44 through the upper left steam chamber inlet hole 41L of the partition 401, and is discharged to the external chamber through the internal chamber steam outlet 45.In this embodiment, although the positions of the upper left steam chamber inlet hole 41L and the upper right steam chamber inlet hole 41R and the specific structure and arrangement of the ribs are different from those of the first embodiment, similarly, the lid assembly has upper and lower two-layer steam chambers, and the upper steam chamber has a labyrinth steam passage, which makes the steam flow path longer and is advantageous for liquid recovery.
[0033] The present disclosure also relates to a liquid heating container including the above-described lid assembly. This container includes a container body 8 with an open upper surface, and a spout 84 and a handle 81 are disposed opposite to each other on the container body 8, and a handle steam passage 82 is provided on the handle 81. When the above lid assembly covers the liquid heating container, the lid steam outlet 25 communicates with the handle steam passage 82, whereby the steam discharged from the lid steam outlet 25 enters the handle steam passage 82, flows to the bottom lid 83 and is condensed, or is discharged to the outside of the container body 8.
