[0001] The present invention relates to the technical field of kitchen appliances, and particularly relates to a steam box. Background Art

[0002] Due to its convenience, speed, and safety, the steam box has now become one of the commonly used kitchen utensils in households. When steaming food, the existing steam box heats water to generate steam, and the steam fills the cavity to steam the food; during the cooking process, the internal pressure of the steam box is greater than the external atmospheric pressure to heat to a higher temperature and shorten the cooking time.

[0003] When the steam box is working, the pressure relief valve will exhaust gas continuously. The area near the top pressure relief valve is in a state of dynamic pressure and steam flow, while the lower part of the cavity is in a state of stable pressure and no steam flow. However, the food ingredients in the steam box are all in the cooking area at the lower part of the cavity, that is, the area with stable pressure and no steam flow, which will cause the steam not to fully contact the food ingredients, resulting in insufficient humidity of the steamed food, dry surface, and slow steaming speed.

[0004] Based on the disadvantages of the existing technology, it is urgent to research a steam box to solve the above problems. Summary of the Invention

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0035] In view of the defects of the prior art, in the present invention, a first gap is formed between the first accommodating cavity and the top of the pot body assembly, a second gap is formed between the second accommodating cavity and the bottom of the pot body assembly, and a third gap is provided between the side wall of the steaming grid and the side wall of the pot body assembly. By arranging a fan assembly in the second accommodating cavity, the gas in the second accommodating cavity can sequentially pass through the second gap, the third gap, the first gap and the first accommodating cavity and circulate, enabling the high-pressure hot steam to quickly circulate along a preset path, improving the cooking speed and humidity, while avoiding excessive local temperature and ensuring the temperature uniformity in the steamer.

[0036] See the attached Figures 1 to 5 As shown in the figure, this embodiment provides a steamer, including: a pot body assembly 1 with a top and a bottom arranged oppositely, and a liquid cavity is provided at the bottom of the pot body assembly 1; a steaming grid 2 arranged in the pot body assembly 1, a partition 21 is arranged in the steaming grid 2, and the partition 21 divides the steaming grid 2 into a first accommodating cavity 11 and a second accommodating cavity 12. A first gap is formed between the first accommodating cavity 11 and the top of the pot body assembly 1, and a second gap is formed between the second accommodating cavity 12 and the bottom of the pot body assembly 1; a third gap is provided between the side wall of the steaming grid 2 and the side wall of the pot body assembly 1; a fan assembly 3 arranged in the second accommodating cavity 12, and the fan assembly 3 can drive the gas in the second accommodating cavity 12 to sequentially pass through the second gap, the third gap, the first gap and the first accommodating cavity 11 and circulate.

[0037] It should be noted that: in this embodiment, a first gap is formed between the first accommodating cavity 11 and the top of the pot body assembly, a second gap is formed between the second accommodating cavity 12 and the bottom of the pot body assembly 1, and a third gap is provided between the side wall of the steaming grid and the side wall of the pot body assembly 1. By arranging a fan assembly 3 in the second accommodating cavity 12, the gas in the second accommodating cavity 12 can sequentially pass through the second gap, the third gap, the first gap and the first accommodating cavity 11 and circulate, enabling the high-pressure hot steam to quickly circulate along a preset path, improving the cooking speed and humidity, while avoiding excessive local temperature and ensuring the temperature uniformity in the steamer.

[0038] It should also be noted that: the pressure in a conventional steamer is balanced, and the steam only has an instinctive upward movement, and due to the balanced pressure, the flow rate is very slow; the steamer in this embodiment realizes the circulation of the steam along a preset path by arranging the fan assembly 3, the first accommodating cavity 11, the second accommodating cavity 12, the first gap, the second gap and the third gap, solves the problems of slow steaming speed and dry surface in a conventional steamer, and further improves the cooking speed and humidity.

[0039] Specifically, a liquid is placed in the liquid cavity, and the above liquid can be converted from a liquid state to a gaseous state under heating conditions.

[0040] Specifically, the preset path of the steam is the second accommodating cavity 12, the second gap, the third gap, the first gap, the first accommodating cavity 11 and the second accommodating cavity 12.

[0041] Specifically, the steaming grid 2 is a housing with openings at both ends. A partition 21 is arranged inside the steaming grid 2. Along the height direction of the steaming grid 2, the steaming grid is divided into a first accommodation cavity 11 and a second accommodation cavity 12 from top to bottom.

[0042] Specifically, a number of ventilation holes are provided on the partition 21, so that the steam in the first accommodation cavity 11 can enter the second accommodation cavity 12 through the ventilation holes.

[0043] Even further, the partition 21 is for placing food, and the first accommodation cavity 11 can be regarded as a food accommodation cavity.

[0044] Specifically, the heights of the first accommodation cavity 11 and the second accommodation cavity 12 do not need to be limited, as long as it is ensured that the first accommodation cavity 11 can accommodate food and the second accommodation cavity 11 can accommodate the fan assembly 3.

[0045] In this embodiment, the height of the first accommodation cavity 11 is greater than the height of the second accommodation cavity 12.

[0046] In some possible embodiments, the height of the first interval is 10 - 20 mm. By setting the first interval within the above range, it is possible to avoid the interval being too small to meet the large - scale steam circulation; since the density of hot steam is low, a large amount of hot steam will accumulate at the top of the pot body assembly 1. If the interval is too large, the fan assembly 3 cannot circulate the steam at the top of the pot body assembly 1, thus reducing the cooking speed. Therefore, setting the interval within the above range can ensure that the steam smoothly flows through the second accommodation cavity 12, the second interval, the third interval, the first interval, and the first accommodation cavity 11 and circulates, realizing the rapid circulation of high - pressure hot steam along a preset path, and improving the cooking speed and humidity.

[0047] Specifically, the height of the first interval is 10 - 11 mm, 10 - 15 mm, 10 - 18 mm, 10 - 20 mm, 12 - 18 mm, 12 - 20 mm, or 15 - 20 mm.

[0048] In some possible embodiments, the interval between the fan blades of the fan assembly 3 and the liquid cavity is not less than 10 mm. By setting it within the above range, it is possible to avoid the interval being too small, so that the steam blown out by the fan assembly 3 does not have enough space to diffuse into the third interval, and the steam will hit the water surface and flow back, greatly reducing the steam circulation efficiency. By setting the interval within the above range, it is possible to ensure the steam circulation efficiency, realize the rapid circulation of high - pressure hot steam along a preset path, and improve the cooking speed and humidity.

[0049] Specifically, the size of the fan blades of the fan assembly 3 varies with the cross-sectional area of the pot body assembly 1. The larger the cross-sectional area of the pot body assembly 1, the larger the fan blades of the fan assembly 3; the smaller the cross-sectional area of the pot body assembly 1, the smaller the fan blades of the fan assembly 3. The size of the fan blades of the fan assembly 3 is not limited, as long as there is enough space for the steam blown by the fan assembly 3 to diffuse into the third interval.

[0050] In some possible embodiments, the height of the third interval is not less than 15 mm. By setting the third interval within the above range, it can be ensured that the steam in the second cavity 12 can smoothly enter the third interval and flow through the third interval to the first interval and the first accommodation cavity 11, thereby realizing the rapid circulation of steam along the preset path, and thus improving the cooking speed and humidity.

[0051] In some possible embodiments, the interval between the fan blades of the fan assembly 3 and the side wall of the steaming grid 2 is 2 - 6 mm. By setting the interval within the above range, it can be ensured that the steam can smoothly enter the second interval, and it can be ensured that the steam flows through the second accommodation cavity 12, the second interval, the third interval, the first interval and the first accommodation cavity 11 and circulates, realizing the rapid circulation of high-pressure hot steam along the preset path, and improving the cooking speed and humidity.

[0052] Specifically, the interval between the fan blades of the fan assembly 3 and the side wall of the steaming grid 2 is 2 - 3 mm, 2 - 4 mm, 2 - 6 mm, 3 - 6 mm or 4 - 6 mm, etc.

[0053] It should be noted that: by setting the first accommodation cavity 11, the second accommodation cavity 12, the first interval, the second interval and the third interval, and setting the interval between the fan blades of the fan assembly 3 and the liquid cavity to be not less than 10 mm, there is enough space for the steam blown by the fan assembly 3 to diffuse into the third interval. The height of the third interval is set to be not less than 15 mm, which can ensure that the steam in the second cavity 12 can smoothly enter the third interval. The interval between the fan blades of the fan assembly 3 and the side wall of the steaming grid 2 is set to 2 - 6 mm, which can ensure that the steam in the second accommodation cavity 12 can smoothly enter the second interval. The height of the first interval is set to 10 - 20 mm, which can ensure that the steam in the first interval smoothly flows into the first accommodation cavity. Thus, through the above settings, the gas in the second accommodation cavity 12 sequentially passes through the second interval, the third interval, the first interval and the first accommodation cavity 11 and circulates, enabling the high-pressure hot steam to rapidly circulate along the preset path, and improving the cooking speed and humidity.

[0054] In some possible embodiments, a clamping portion 23 is provided on the side wall of the steaming grid 2; the clamping portion 23 is clamped and fixed to the inner side wall of the pot body assembly 1, and the steaming grid 2 is fixed to the inner side wall of the pot body assembly 1, which can prevent the steaming grid 2 from falling off the pot body assembly 1 and interfering with the fan assembly 3. At the same time, it is ensured that during the operation of the steamer, the first interval and the second interval are maintained within a preset interval range; by providing the clamping portion 23 for clamping, the steaming grid 2 is convenient to disassemble and install.

[0055] Specifically, a plurality of clamping portions 23 are provided at intervals on the side wall of the steaming grid 2.

[0056] Specifically, the number and arrangement position of the clamping portions 23 are not limited, as long as it is ensured that the steaming grid 2 can be clamped and fixed to the inner wall of the pot body assembly 3 through the clamping portions 23.

[0057] In this embodiment, the number of the clamping portions 23 is four, and the four clamping portions 23 are arranged at intervals on the side wall of the steaming grid 2.

[0058] Specifically, the clamping portion 23 is a protrusion provided on the side wall of the steaming grid 2, and a limiting groove matching the protrusion on the side wall of the steaming grid 2 is provided on the inner wall of the pot body assembly 1. The protrusion is arranged in the limiting groove for restricting the movement of the steaming grid 2 towards the fan assembly 3.

[0059] Further, the vertical distance between the limiting groove and the bottom of the pot body assembly 1 is greater than the maximum vertical distance between the fan assembly 3 and the bottom of the pot body assembly 1, so as to prevent the partition 21 of the steaming grid 2 from interfering with the fan assembly, and further prevent affecting the operation of the fan assembly 3.

[0060] In this embodiment, the clamping portion 23 and the partition 21 are arranged on the same plane.

[0061] In some possible embodiments, the cross-sectional area of the pot body assembly 1 is not limited herein.

[0062] Specifically, the cross-sectional area of the pot body assembly 1 can be a circular or square structure, etc.

[0063] Further, when the cross-sectional area of the pot body assembly 1 is square, the four clamping portions 23 are arranged at equal intervals along the circumferential direction of the steaming grid 2, so that all the four clamping portions 23 can be clamped to the inner wall of the pot body assembly 1.

[0064] In some possible embodiments, a heating device 4 for heating the liquid in the pot body assembly 1 is further included. The heating device 4 is arranged at the bottom of the pot body assembly 1. By providing the heating device 4, the liquid in the liquid cavity of the pot body assembly 1 can be heated to be converted from a liquid state to a gaseous state, thereby realizing gas dynamic circulation, and thus improving the cooking speed and humidity.

[0065] Specifically, the heating device 4 is of an annular structure. By setting the heating device 4 as an annular shape, the heating device 4 can be sleeved outside the driving member 32 of the fan assembly 3, and there is a gap between the heating device 4 and the fan assembly 3, which can ensure heating the pot body assembly 1 while avoiding heating the driving member 32 by the heating device 4, resulting in damage due to overheating of the driving member 32. Moreover, since the heating device 4 is sleeved outside the driving member 32, it can save installation space and prevent the overall structure from being too large.

[0066] Furthermore, the heating device 4 is an electromagnetic heating plate.

[0067] In some possible embodiments, it further includes a second housing 5 with an opening, a door assembly 6, and a base 7 capable of accommodating the pot body assembly 1; after the second housing 5 and the door assembly 6 are connected, a sealed cavity is formed; the base 7 is arranged in the sealed cavity; one end of the base 7 is slidably connected to the second housing 5, and the other end of the base 7 is fixedly connected to the door assembly 6; under the action of an external force, the door assembly 6 can drive the base 7 to move towards or away from the opening direction of the second housing 5. Through the mutual connection and cooperation of the second housing 5, the base 7, and the door assembly 6, a steamer capable of bearing high pressure is formed, ensuring that the steamer can perform high-pressure cooking and other operations.

[0068] Specifically, a slide rail structure is arranged on the base 7. One side of the slide rail structure is connected to the base 7, and the other side is connected to the inner wall of the second housing 5. Through the slide rail structure, the base 7 is slidably connected to the second housing 5.

[0069] In some possible embodiments, a lid structure is arranged on the top of the pot body assembly 1, and the lid structure is detachably connected to the top of the pot body assembly 1.

[0070] Specifically, a pressure relief valve is arranged on the lid structure.

[0071] In some possible embodiments, the fan assembly 3 includes a driving member 32 and a fan 31; the fan 31 is arranged inside the pot body assembly 1, the driving member 32 is fixed on the base 7, the driving end of the driving member 32 passes through the bottom of the pot body assembly 1 and is drivingly connected to the fan 31. The structure of the fan assembly 3 is simple. By driving the fan 31 to rotate inside the pot body assembly 1 by the driving member 32, the driving of the steam to flow along a preset path can be realized.

[0072] Specifically, after the driving end of the driving member 32 passes through the bottom of the pot body assembly 1, the driving end is sealingly connected to the bottom of the pot body assembly 1 to prevent the liquid inside the pot body assembly 1 from flowing out.

[0073] In some possible embodiments, the steamer further includes a controller and a sensor assembly, and the controller and the sensor assembly are electrically connected; the sensor assembly is used to obtain the liquid level information of the liquid inside the pot body assembly 1; the controller is used to control the operation of the heating device 4 according to the liquid level information.

[0074] In some other possible embodiments, the steam box further includes a control panel for an operator to operate, and the control panel can adjust the liquid volume and the temperature inside the pot body assembly 1.

[0075] Specifically, the controller is electrically connected to the control panel and the driving member 32 respectively.

[0076] In some possible embodiments, the rotation direction of the fan assembly 3 is arranged parallel to the axial direction of the pot body assembly 1. When the fan assembly 3 rotates, it can ensure that the steam flows from the second cavity 12 to the second interval and the third interval in sequence, ensuring that the steam flows along a preset path, thereby ensuring the humidity inside the pot body assembly 1.

[0077] Working process of the steam box: When the steam box is required to cook food, the operator pulls the door assembly 6, and the door assembly 6 drives the base 7 away from the opening of the second housing 5; the food is placed on the partition 21, and the operator pushes the door assembly 6, and the door assembly 6 drives the base 7 to move towards the opening of the second housing 5 until the door assembly 6 and the second housing 5 form a sealed housing; the heating device 4 is controlled to heat the liquid inside the pot body assembly 1, and the fan assembly 3 is controlled to rotate, so that the gas in the second accommodation cavity 12 sequentially passes through the second interval, the third interval, the first interval and the first accommodation cavity 11 and circulates.

The larger the cross-sectional area of the pot body assembly 1, the larger the fan blades of the fan assembly 3; the smaller the cross-sectional area of the pot body assembly 1, the smaller the fan blades of the fan assembly 3. The size of the fan blades of the fan assembly 3 is not limited, as long as there is enough space for the steam blown by the fan assembly 3 to diffuse into the third interval.

By arranging the heating device 4 as an annular shape, the heating device 4 can be sleeved outside the driving member 32 of the fan assembly 3, and there is a gap between the heating device 4 and the fan assembly 3, which can ensure heating of the pot body assembly 1, while avoiding heating the driving member 32 by the heating device 4, resulting in damage due to excessive temperature of the driving member 32. And the heating device 4 is sleeved outside the driving member 32, which can save installation space and avoid the overall structure from being too large.
