Description

Technical Field

[0001] This utility model belongs to the field of steam boilers, and in particular relates to a steam boiler structure and a steam boiler. Background Technology

[0002] Traditional steam pots, especially those used to prepare classic dishes such as "steamed chicken in a clay pot," work by using steam in a closed-loop cooking process. A typical traditional steam pot structure usually has a hollow steam pipe in the center of the pot. Steam enters from the bottom of the pot through this pipe, exits from an opening at the top, rises to the lid where it condenses into water droplets, and drips back onto the food inside, gradually cooking the food and forming a broth.

[0003] However, the aforementioned structure, with the steam pipe located in the center of the pot, occupies space inside the pot, limiting the space for placing food and making cleaning inconvenient. To address these issues, an improved solution has been proposed in related technologies: the steam channel is built into the side wall or lid of the pot, and steam is introduced by opening steam vents on the inner side of the side wall. This design effectively increases the effective volume of the pot.

[0004] However, both of these methods still have drawbacks. First, after the steam rises, it first exchanges heat with the cooler lid, resulting in a significant loss of heat energy due to the lid's cooling rather than its direct use in heating the food. The steam's heat is not fully and effectively utilized, leading to slow heating of the food and longer cooking times. Second, a large amount of uncondensed steam quickly escapes from the gaps between the lid and the pot, causing significant heat and moisture loss, resulting in low energy efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a boiler structure and boiler to solve the problems of low thermal efficiency and low energy utilization efficiency of boilers in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a steam boiler structure, including: a boiler body, a steam channel provided in the side wall of the boiler body, the inlet of the steam channel being located on the bottom outer side of the boiler body, the outlet of the steam channel being located on the top inner side of the boiler body, and the outlet of the steam channel being oriented towards the bottom of the boiler body.

[0007] Optionally, there may be multiple steam passages.

[0008] Optionally, multiple steam passages are arranged in a ring with uniform intervals.

[0009] On the other hand, a steam pot is also provided, including a lid and a steam pot structure as described above, the lid being used to cover the pot body.

[0010] Optionally, the lid is provided with a vent.

[0011] Optionally, it also includes a pick-and-place mechanism, which is detachably connected to the rim of the pot body.

[0012] Optionally, a limiting groove is provided on the side of the pot body facing the bottom; the picking and placing mechanism includes a fixed rod, a mounting base and multiple claw assemblies; the mounting base is set on the fixed rod, the claw assemblies are spaced apart on the mounting base and rotatably connected to the mounting base, and the claw assemblies are used to connect with the limiting groove.

[0013] Optionally, the claw assembly includes a claw body and a rotating rod. One end of the rotating rod is rotatably connected to the mounting base, and the other end is detachably connected to the claw body. The claw body is used to connect with the limiting groove.

[0014] Optionally, the pick-and-place mechanism further includes a limiting seat and a fixed seat; the fixed seat is threadedly connected to the fixed rod; the limiting seat is sleeved on the fixed rod and can move upward along the axial direction of the fixed rod, and the limiting seat is located between the mounting seat and the fixed seat; the fixed seat drives the rotating rod to rotate relative to the mounting seat by moving the limiting seat.

[0015] Optionally, the mounting base is provided with multiple mounting slots, each corresponding to a rotating rod, and the extension direction of the mounting slot is parallel to the axis of the fixed rod; the rotating rod is rotatably connected to the mounting slot via a rotating shaft; at least part of the outer side of the connection end between the rotating rod and the mounting slot is an arc-shaped abutment part; the end of the limiting seat facing the mounting base is provided with multiple triangular limiting blocks corresponding to the mounting slots; the triangular limiting blocks are used to abut against the abutment part.

[0016] As described above, the steam boiler structure and steam boiler of this utility model have at least the following beneficial effects:

[0017] By incorporating steam channels within the side wall of the pot, with the outlet of these channels located on the inner top of the pot and facing towards the bottom, steam enters the containment cavity through the steam channel outlet and is then directly sprayed onto the surface of the food within the containment cavity. This "jet" effect results in stronger thermal convection and direct thermal impact, significantly improving heat exchange efficiency and allowing food (especially large pieces or hard-to-cook tubers and meats) to heat up faster, thus shortening cooking time.

[0018] Furthermore, the downward-spraying steam creates turbulence and vortices within the limited space at the bottom of the pot, rather than simply dissipating upwards. This turbulence ensures a more even distribution of heat and humidity within the pot, preventing localized overheating or drying. Simultaneously, the turbulence allows ingredients and seasonings to mix thoroughly, enabling all parts of the food to absorb flavor more evenly.

[0019] Furthermore, the downward-spraying steam is obstructed by the food and the bottom of the pot, effectively extending its flow path. The steam circulates fully within the pot, completing heat exchange and condensing into water before slowly escaping upwards. This not only significantly extends the residence time of the steam within the pot, improving thermal efficiency and thus greatly enhancing energy utilization and achieving energy savings, but also completely avoids the steam flow directly impacting the pot lid, preventing problems such as collisions, vibrations, and seal failures between the lid and the pot body.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0030] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0031] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0032] Please see Figure 1 This utility model provides a steam pot, which includes a pot body 1 and a pot lid 2. The pot body 1 is provided with a receiving cavity for holding food. The top of the pot body 1 is provided with a feeding port, through which food can be put into the receiving cavity, or the steamed food can be taken out through the feeding port.

[0033] like Figure 2-3 As shown, a steam passage 11 for steam to pass through is provided in the side wall of the pot body 1. The inlet of the steam passage 11 is located on the bottom outside of the pot body 1, and the outlet of the steam passage 11 is located on the top inside of the pot body 1. The outlet of the steam passage 11 is set towards the bottom of the pot body 1, that is, the outlet is set towards the bottom of the receiving cavity.

[0034] Multiple steam channels 11 can be configured, and the multiple steam channels 11 are spaced apart on the side wall of the pot body 1. The outlets of the multiple steam channels 11 are on the same horizontal plane. Preferably, the multiple steam channels 11 are arranged in a ring and evenly spaced on the side wall of the pot body 1.

[0035] like Figure 3 As shown, after steam enters the receiving cavity through the outlet of steam channel 11, the steam is directly sprayed onto the surface of the food inside the receiving cavity. This "jet" effect brings stronger thermal convection and direct thermal impact, which significantly improves heat exchange efficiency, allowing food (especially large pieces or hard-to-cook tubers and meats) to heat up faster and shorten cooking time.

[0036] The downward-spraying steam creates turbulence and vortices within the limited space at the bottom of the pot, rather than simply dissipating upwards. This turbulence ensures a more even distribution of heat and humidity within the pot, preventing localized overheating or drying. Simultaneously, the turbulence allows ingredients and seasonings to mix thoroughly, enabling all parts of the food to absorb flavors more evenly.

[0037] The downward-spraying steam is blocked by the food and the bottom of the pot, effectively extending its flow path. The steam circulates fully inside the pot, completing heat exchange and condensing into water before slowly escaping upwards. This not only significantly extends the residence time of the steam inside the pot, improving thermal efficiency and thus greatly enhancing energy utilization and achieving energy savings, but also completely avoids the steam flow directly impacting the lid 2, preventing problems such as collision, vibration, and seal failure between the lid 2 and the pot body 1.

[0038] To prevent excessive air pressure inside the containment cavity, in this embodiment, the pot lid 2 is provided with an exhaust hole 21.

[0039] Please see Figure 4-5 After use, the boiler body 1 is very hot, and directly handling it can easily burn your hands. Therefore, this embodiment also provides a handling mechanism 3, which is detachably connected to the rim of the boiler body 1 for safely transferring the boiler.

[0040] Specifically, the pick-and-place mechanism 3 includes a fixed rod 31, a mounting base 32, and multiple claw assemblies 33. A gripping ring or gripping rod can be provided at the top of the fixed rod 31 for holding. The mounting base 32 is mounted on the fixed rod 31; in this embodiment, the two are connected by a thread for easy disassembly. The claw assemblies 33 are spaced apart on the mounting base 32 and rotatably connected to it, facilitating the pick-and-place mechanism 3 to accommodate and adapt to pots 1 of different sizes. A limiting groove 12 is provided circumferentially on the side of the pot rim facing the bottom of the pot body 1, and the claw assemblies 33 are used to engage with this limiting groove 12.

[0041] The number of claw assemblies 33 can be set to 2, 3, 4, etc., preferably at least 3, to ensure that the claw assemblies 33 do not separate from the boiler when the pick-and-place mechanism 3 is transferring the boiler. The claw assembly 33 may include a claw body 331 and a rotating rod 332. One end of the rotating rod 332 is rotatably connected to the mounting base 32, and the other end is detachably connected to the claw body 331. The claw body 331 is used to connect with the limiting groove 12. The claw body 331 and the rotating rod 332 can be threaded together. Specifically, a threaded hole can be provided on the rotating rod 332, and the connecting section between the claw body 331 and the rotating rod 332 is provided with external threads to achieve the threaded connection. By making the connection between the claw body 331 and the rotating rod 332 detachable, different lengths or sizes of claw bodies 331 can be used to adapt to different boiler sizes. A hook is provided at the end of the claw body 331 away from the rotating rod 332. The hook is used to connect with the limiting groove 12, thereby preventing the claw body 331 from separating from the boiler during transfer.

[0042] The pick-and-place mechanism 3 also includes a limiting seat 34 and a fixed seat 35; the fixed seat 35 is threadedly connected to the fixed rod 31; the limiting seat 34 is sleeved on the fixed rod 31 and can move upward along the axial direction of the fixed rod 31, and the limiting seat 34 is located between the mounting base 32 and the fixed seat 35; the fixed seat 35 drives the limiting seat 34 to move, thereby driving the rotating rod 332 to rotate relative to the mounting base 32. The lower end of the fixed seat 35 or the upper end of the limiting seat 34 can be rounded to reduce the contact area between the fixed seat 35 and the limiting seat 34, thereby reducing the friction between the fixed seat 35 and the limiting seat 34, making it easier for the user to use.

[0043] The mounting base 32 is provided with multiple mounting slots 321, each corresponding to a rotating rod 332. The extending direction of the mounting slots 321 is parallel to the axial direction of the fixed rod 31. The rotating rod 332 is rotatably connected to the mounting slot 321 via a rotating shaft. At least part of the outer side of the connection end between the rotating rod 332 and the mounting slot 321 is an arc-shaped abutment portion 3321. The end of the limiting seat 34 facing the mounting base 32 is provided with multiple triangular limiting blocks 341, each corresponding to a mounting slot 321. The triangular limiting blocks 341 are used to abut against the abutment portion 3321. When the fixed base 35 moves the limiting seat 34, the triangular limiting blocks 341 abut against the side wall of the mounting slot 321, thereby guiding the movement of the limiting seat 34. Furthermore, the triangular limiting block 341 abuts against the abutting part 3321 of the rotating rod 332, thereby driving the rotating rod 332 to rotate, so as to ensure that the multiple claws abut against the edge of the pot body 1.

[0044] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
