Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, specifically to a liquid heating container. Background Technology

[0002] In existing liquid heating containers such as health pots, the viscosity of the liquid increases when cooking food. This increased viscosity causes the liquid to foam very easily during heating. To prevent foam from overflowing from the lid, current health pots typically use a sensor at the spout to pause heating upon detecting foam and resume heating once the foam subsides. Alternatively, they use a silicon controlled rectifier (SCR) to achieve low-power heating during the heating process. This necessitates setting the average power very low, resulting in a long cooking time. Utility Model Content

[0003] This application aims to at least solve the problem in the above-mentioned prior art or related technologies that food is easily boiled in a health pot, and in order to avoid the foam overflowing out of the pot, the average power of the health pot needs to be set to a very low level, resulting in a long cooking time.

[0004] Therefore, the first aspect of this utility model provides a liquid heating container, comprising: a pot body having a spout; a lid assembly covering the spout, the lid assembly including an upper lid and a lower lid connected to each other, the upper lid and the lower lid forming a first bubble-breaking cavity, the first bubble-breaking cavity having a foam inlet communicating with the interior of the pot body and a foam outlet communicating with the exterior of the lid assembly; and a stop portion disposed on the outer wall of the lid assembly or on the inner wall of the pot body, the stop portion being arranged in a circumferential direction, the stop portion, the outer wall of the lid assembly, and the inner wall of the pot body located above the stop portion forming a second bubble-breaking cavity, the second bubble-breaking cavity communicating with the first bubble-breaking cavity through the foam outlet.

[0005] The liquid heating container proposed in this embodiment includes a pot body, a lid assembly, and a stop. The lid assembly and the pot body enclose and form a first bubble-breaking chamber and a second bubble-breaking chamber that are interconnected. By setting the first bubble-breaking chamber and the second bubble-breaking chamber, a three-temperature zone space is formed between the lid assembly and the pot body. The foam generated by heating food in the pot body can enter the first bubble-breaking chamber and the second bubble-breaking chamber in sequence and be eliminated therein, realizing the function of step-by-step bubble breaking. This can effectively prevent the foam in the pot body from overflowing, maintain a higher average power when cooking food, effectively ensure the high temperature inside the food, and improve the taste of the food and soup. At the same time, it can also effectively break and eliminate bubbles, heat food with greater power, and thus reduce the cooking time. Specifically, the three-temperature zone includes the highest-temperature zone enclosed by the stop and the side wall of the pot body located below the stop; the first bubble-breaking chamber (also known as the second-lowest-temperature zone) with a moderate temperature; and the second bubble-breaking chamber (also known as the cooling zone) connected to the outside of the pot body with the lowest temperature. During cooking, the food is heated in the highest-temperature zone, and the resulting foam enters the first bubble-breaking chamber through the foam inlet. At this point, most of the foam collapses rapidly and becomes smaller due to entering the second-lowest-temperature zone, allowing the heating device to continue heating the food without causing the foam to overflow. If the amount of foam is too large, it can enter the second bubble-breaking chamber (i.e., the cooling zone) after passing through the first bubble-breaking chamber, further reducing its temperature and causing it to collapse rapidly, preventing it from overflowing.

[0006] In some embodiments, the lower cover includes a lower cover sidewall, a lower cover bottom wall extending radially inward from the lower end of the lower cover sidewall, and an annular extension wall extending upward from the lower cover bottom wall, with the upper end of the annular extension wall forming a foam inlet. This configuration allows the annular extension wall to form a channel for foam generated within the pot to enter the first foam-breaking chamber. Positioning the foam inlet at the top of the annular extension wall eliminates some of the foam before it enters the foam inlet, further enhancing the foam-breaking effect. Furthermore, positioning the foam inlet above the bottom wall of the lower cover prevents foam entering the first foam-breaking chamber from falling back into the pot through the foam-breaking inlet.

[0007] In some embodiments, the annular extension wall extends obliquely upwards, forming a trumpet shape with a large opening at the lower end and a small opening at the upper end. This configuration results in a large inlet for the channel formed by the annular extension wall, allowing more foam to enter quickly. The small opening at the upper end of the channel causes the foam inside to compress each other as it rises, leading to the rupture of some foam and further improving the foam breaking efficiency.

[0008] In some embodiments, the bottom wall of the lower cover is curved, and the trajectory of the annular extension wall extending obliquely upward from the bottom wall of the lower cover is an arc. This configuration allows adjustment of the curvature of the arc to change the size of the channel inlet and the foam inlet, resulting in a smoother structure for the lower cover.

[0009] In some embodiments, the lower end of the bottom wall and / or the annular extension wall of the lower cover is provided with a plurality of filter holes, which are distributed in a multi-ring pattern. This arrangement allows the liquid formed after the foam in the first bubble-breaking chamber bursts to flow back into the kettle body through the filter holes, preventing liquid accumulation within the kettle lid assembly. Furthermore, the multi-ring distribution of the filter holes ensures uniform distribution, with filter holes at every angle along the circumference of the lower cover, enabling simultaneous liquid return and thus accelerating the rate at which the liquid returns to the kettle body.

[0010] In some embodiments, a plurality of through holes are provided on the side wall of the lower cover, and the plurality of through holes are distributed circumferentially along the side wall of the lower cover, forming a foam outlet. This arrangement, with the foam outlet located on the side wall of the lower cover, facilitates installation, and allows the foam in the first foam-breaking chamber to flow outward through the side wall of the lower cover into the space between the side wall of the lower cover and the inner side wall of the pot. The foam flow path is also reasonable, which is more conducive to achieving foam breaking and overflow prevention.

[0011] In some embodiments, the stop is a ring of ribs extending radially outward from the outer wall of the lower cover, with a certain gap between it and the inner wall of the pot body. The ribs have a simple structure, are easy to manufacture, and can be integrally molded with the lower cover using processes such as injection molding, saving production costs. Furthermore, the gap between the ribs and the pot body prevents interference when the lid assembly is closed onto the pot body, facilitating the removal and closing of the lid assembly.

[0012] In some embodiments, the upper and lower covers are detachably snap-fit ​​connected. This configuration allows the upper and lower covers to be disassembled for cleaning, solving the problem of foam residue accumulating in the first foam-breaking chamber and being difficult to clean, thus improving the cleanliness of the product. In addition, the snap-fit ​​connection structure is simple, easy to disassemble and assemble, and has a low cost.

[0013] Specifically, in some embodiments, one of the connecting rings of the upper cover and the sidewall of the lower cover has multiple protrusions spaced circumferentially along its upper edge, and the other has multiple grooves, with the protrusions engaging in the grooves. Specifically, the groove includes a guide groove extending axially to the edge of the upper or lower cover, and a limiting groove connected to the guide groove and extending radially. The protrusion can be inserted into the limiting groove via the guide groove and rotated to move into the interior of the limiting groove.

[0014] In some embodiments, the liquid heating container further includes a lid sealing ring. The lid includes a lid body and a connecting ring extending downward from the lower surface of the lid body. A first limiting rib is provided on the outer side wall of the connecting ring. The lid sealing ring is sleeved on the connecting ring and limited by the first limiting rib. The lid sealing ring can seal the gap between the lid and the container body.

[0015] In these embodiments, the lid sealing ring is fitted onto the upper cover to seal the gap between the upper cover and the kettle body. Specifically, two first limiting ribs are provided on the outer wall of the connecting ring of the upper cover, and the lid sealing ring is located between the two first limiting ribs. Thus, the first limiting ribs can limit the lid sealing ring, prevent the lid sealing ring from shifting on the connecting ring, and ensure the sealing effect.

[0016] In some embodiments, the liquid heating container further includes a lid sealing ring, which is sleeved on the side wall of the lower cover and located below the foam outlet. A second limiting rib is provided on the outer surface of the side wall of the lower cover, which is located below the stop portion. The lid sealing ring is located between the second limiting rib and the stop portion, and the lid sealing ring can seal the gap between the lower cover and the container body.

[0017] In these embodiments, the lid sealing ring is fitted onto the lower lid to seal the gap between the lower lid and the pot body. Furthermore, positioning the lid sealing ring below the foam outlet ensures that foam does not obstruct its entry into the second bubble-breaking chamber, while simultaneously isolating the second bubble-breaking chamber from the high-temperature zone inside the pot body. This effectively reduces the impact of the high-temperature zone on the temperature within the second bubble-breaking chamber, maintaining a lower temperature. Specifically, a second limiting rib is provided on the outer surface of the lower lid's sidewall. The lid sealing ring is located between the second limiting rib and the stop portion, thus limiting the lid sealing ring and preventing it from shifting on the lower lid's sidewall, ensuring a proper seal.

[0035] The following will combine Figures 1 to 4 Liquid heating containers according to some embodiments of this application.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, the first aspect of this utility model provides a liquid heating container, including: a pot body 10, the pot body 10 having a spout 110; a lid assembly 20, the lid assembly 20 covering the spout 110, the lid assembly 20 including an upper lid 210 and a lower lid 220 connected to each other, the upper lid 210 and the lower lid 220 enclosing to form a first bubble-breaking cavity 230, the first bubble-breaking cavity 230 being provided with a foam inlet 231 communicating with the interior of the pot body 10 and a foam outlet 232 communicating with the exterior of the lid assembly 20; a stop portion 240, disposed on the outer wall of the lid assembly 20 or the inner wall of the pot body 10, the stop portion 240 being arranged in a circle in the circumferential direction, the stop portion 240, the outer wall of the lid assembly 20 and the inner wall of the pot body 10 located above the stop portion 240 enclosing to form a second bubble-breaking cavity 260, the second bubble-breaking cavity 260 communicating with the first bubble-breaking cavity 230 through the foam outlet 232.

[0037] The liquid heating container proposed in this embodiment includes a pot body 10, a lid assembly 20, and a stop 240. The lid assembly 20 and the pot body 10 enclose and form a first bubble-breaking chamber 230 and a second bubble-breaking chamber 260 that are interconnected. By setting the first bubble-breaking chamber 230 and the second bubble-breaking chamber 260, a space with three temperature zones is formed between the lid assembly 20 and the pot body 10. The foam generated by heating food in the pot body 10 can enter the first bubble-breaking chamber 230 and the second bubble-breaking chamber 260 in sequence and be eliminated therein, realizing the function of step-by-step bubble breaking. This can effectively prevent the foam in the pot body 10 from overflowing, maintain a higher average power when cooking food, effectively ensure the high temperature inside the food, and improve the taste of the food and soup. At the same time, it can also effectively break and eliminate bubbles, heat food with greater power, and thus reduce the cooking time. Specifically, the three temperature zones include the highest temperature zone enclosed by the stop section 240 and the side wall of the pot body 10 located below the stop section 240; the first bubble-breaking chamber 230 (also known as the second lowest temperature zone) with a moderate temperature; and the second bubble-breaking chamber 260 (also known as the cooling zone) connected to the outside of the pot body 10 with the lowest temperature. During cooking, the food is heated in the highest temperature zone of the three temperature zones, and the resulting foam enters the first bubble-breaking chamber 230 through the foam inlet 231. At this time, most of the foam collapses rapidly and becomes smaller because it enters a second lowest temperature zone. This allows the heating device to continue heating the food without causing the foam to overflow from the pot. If the amount of foam is too large, the foam can also enter the second bubble-breaking chamber 260 (also known as the cooling zone) after passing through the first bubble-breaking chamber 230, which can further reduce the temperature of the foam, causing the foam to collapse rapidly and preventing the foam from overflowing from the pot.

[0038] It is worth noting that in some embodiments, a spout 120 is provided at the mouth 110 of the pot body 10. When the lid assembly 20 is closed at the mouth 110, a gap is left at the spout 120 for pouring water, so that the second bubble-breaking chamber 260 can be connected to the outside through the spout 120.

[0039] Regarding the specific structure of the lower cover 220, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the lower cover 220 includes a lower cover side wall 221, a lower cover bottom wall 222 extending radially inward from the lower end of the lower cover side wall 221, and an annular extension wall 223 extending upward from the lower cover bottom wall 222. The upper end of the annular extension wall 223 forms a foam inlet 231. With this configuration, the annular extension wall 223 forms a channel for the foam generated in the kettle body 10 to enter the first foam breaking chamber 230. By placing the foam inlet 231 at the top of the annular extension wall 223, a portion of the foam is eliminated in the channel formed by the annular extension wall 223 before entering the foam inlet, further improving the foam breaking effect. Furthermore, placing the foam inlet 231 above the lower cover bottom wall 222 also prevents the foam entering the first foam breaking chamber 230 from falling back into the kettle body 10 through the foam breaking inlet.

[0040] Furthermore, the annular extension wall 223 extends obliquely upwards, forming a trumpet shape with a large opening at the lower end and a small opening at the upper end. This design results in a large inlet to the channel formed by the annular extension wall 223, allowing more foam to enter quickly. The small opening at the upper end of the channel causes the foam inside to compress each other as it rises, leading to the rupture of some foams and further improving the foam breaking efficiency.

[0041] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the bottom wall 222 of the lower cover is curved, and the annular extension wall 223 extends upward from the bottom wall 222 in an arc. This design allows for adjustment of the curvature of the arc to change the size of the channel inlet and the foam inlet 231, making the structure of the lower cover 220 smoother.

[0042] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, the lower end of the bottom wall 222 and / or the annular extension wall 223 of the lower cover is provided with a plurality of filter holes 250, which are distributed in a multi-ring pattern. This arrangement allows the liquid formed after the foam in the first bubble-breaking chamber 230 breaks to flow back into the pot body 10 through the filter holes 250, preventing liquid accumulation in the lid assembly 20. Furthermore, the multi-ring distribution of the filter holes 250 ensures uniform distribution, with filter holes 250 at every angle along the circumference of the lower cover 220, enabling simultaneous liquid backflow and thus accelerating the rate at which the liquid flows back into the pot body 10.

[0043] Regarding the setting of the foam outlet 232, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, multiple through holes are provided on the side wall 221 of the lower cover, and these through holes are distributed circumferentially along the side wall 221, forming a foam outlet 232. This arrangement, placing the foam outlet 232 on the side wall 221 of the lower cover, facilitates installation. Furthermore, the foam in the first foam-breaking chamber 230 can flow outward through the side wall 221 of the lower cover to the space between the side wall 221 of the lower cover and the inner side wall of the pot body 10. The foam flow path is also reasonable, which is more conducive to achieving foam breaking and overflow prevention.

[0044] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the stop portion 240 is a ring of ribs extending radially outward on the outer wall of the lower cover 220, with a certain gap between it and the inner wall of the pot body 10. The rib has a simple structure, is easy to process and produce, and can be integrally molded with the lower cover 220 through processes such as injection molding, saving production costs. Furthermore, the certain gap between the rib and the pot body 10 can prevent interference when the lid assembly 20 is closed onto the pot body 10, making it convenient to remove and close the lid assembly 20.

[0045] Of course, the ribs may not be integrally formed with the lower cover 220. They may be manufactured separately and then assembled later by means of bonding, welding, snap-fit ​​connection, screw connection, etc. Specific situations in this regard will not be listed here, but all of them are within the scope of protection of this solution without departing from the design concept.

[0046] In some embodiments, the distance between the ribs and the inner wall of the pot body 10 is greater than or equal to 0.2 mm and less than or equal to 3 mm. Within this range, on the one hand, it ensures that there is sufficient gap between the ribs and the inner wall of the pot body 10, avoiding interference problems when the lid assembly 20 is closed on the pot body 10, and facilitating the removal and closing of the lid assembly 20; on the other hand, it avoids the problem that if the distance between the ribs and the inner wall of the pot body 10 is too large, the heat insulation effect of the ribs will be poor, resulting in a high temperature in the second bubble-breaking chamber 260, which will affect the bubble-breaking effect.

[0047] In some embodiments, the upper and lower covers are detachably snap-fit ​​connected. This configuration allows the upper and lower covers to be disassembled for cleaning, solving the problem of foam residue accumulating in the first foam-breaking chamber and being difficult to clean, thus improving the cleanliness of the product. In addition, the snap-fit ​​connection structure is simple, easy to disassemble and assemble, and has a low cost.

[0048] Specifically, in some embodiments, one of the connecting rings of the upper cover and the sidewall of the lower cover has multiple protrusions spaced circumferentially along its upper edge, and the other has multiple grooves, with the protrusions engaging in the grooves. Specifically, the groove includes a guide groove extending axially to the edge of the upper or lower cover, and a limiting groove connected to the guide groove and extending radially. The protrusion can be inserted into the limiting groove via the guide groove and rotated to move into the interior of the limiting groove.

[0049] In some embodiments, such as Figure 2 As shown, the liquid heating container also includes a lid sealing ring 30. The upper cover 210 includes an upper cover body 211 and a connecting ring body 212 extending downward from the lower surface of the upper cover body 211. Two first limiting ribs 213 are provided on the outer side wall of the connecting ring body 212. The lid sealing ring 30 is sleeved on the connecting ring body 212 and located between the two first limiting ribs 213. The lid sealing ring 30 can seal the gap between the upper cover 210 and the pot body 10.

[0050] In these embodiments, the lid sealing ring 30 is fitted onto the upper cover 210 to seal the gap between the upper cover 210 and the kettle body 10. Specifically, two first limiting ribs 213 are provided on the outer wall of the connecting ring body 212 of the upper cover 210. The lid sealing ring 30 is located between the two first limiting ribs 213, so that the first limiting ribs 213 can limit the lid sealing ring 30, prevent the lid sealing ring 30 from shifting on the connecting ring body 212, and ensure the sealing effect.

[0051] In some embodiments, such as Figure 3As shown, the liquid heating container also includes a lid sealing ring 30, which is sleeved on the side wall 221 of the lower cover and located below the foam outlet 232. A second limiting rib 224 is provided on the outer surface of the side wall 221 of the lower cover, which is located below the stop portion 240. The lid sealing ring 30 is located between the second limiting rib 224 and the stop portion 240, and can seal the gap between the lower cover 220 and the container body 10.

[0052] In these embodiments, the lid sealing ring 30 is fitted onto the lower cover 220 to seal the gap between the lower cover 220 and the pot body 10. Furthermore, the lid sealing ring 30 is positioned below the foam outlet 232, which neither hinders the entry of foam into the second bubble-breaking chamber 260 through the foam outlet 232, nor prevents the second bubble-breaking chamber 260 from the high-temperature zone inside the pot body 10. This effectively reduces the impact of the high-temperature zone on the temperature in the second bubble-breaking chamber 260, keeping the second bubble-breaking chamber 260 at a lower temperature. Specifically, a second limiting rib 224 is provided on the outer surface of the lower cover side wall 221. The lid sealing ring 30 is located between the second limiting rib 224 and the stop portion 240, thereby limiting the lid sealing ring 30 and preventing it from shifting on the lower cover side wall 221, ensuring a sealing effect.

[0053] In some embodiments, as an example, the liquid heating container may optionally be an electric kettle, a health-preserving kettle, etc.

[0054] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
