[0029] For steam cookers such as rice steamers or steam pots, a large amount of water vapor will be emitted during use. The diffusion of a large amount of water vapor into the kitchen environment will affect the vision of the cook, and at the same time, the heat carried by the water vapor will also cause discomfort to the human body.
[0030] The utility model provides a steam interception device, aiming to solve the technical problem of how to reduce the water vapor emitted when using a steam cooker.
[0031] In an embodiment of the utility model, as Figure 1 and Figure 2 shown, the steam interception device includes: a steam collecting hood 10, the steam collecting hood 10 includes a top plate 11 and a surrounding plate 12 connected to the periphery of the top plate 11, the top plate 11 and the surrounding plate 12 enclose a steam collecting cavity 13, the top plate 11 is provided with a steam through hole 111, a stop flange 112 is convexly provided on the periphery of the steam through hole 111, and the stop flange 112 bends towards the inside of the steam collecting cavity 13 to block the steam around the steam through hole 111 from flowing towards the steam through hole 111; a steam adsorption net disk 20, the steam adsorption net disk 20 is a three-dimensional porous structure, the steam adsorption net disk 20 is rotatably installed in the steam collecting cavity 13, the steam adsorption net disk 20 corresponds to and covers the steam through hole 111, and the steam adsorption net disk 20 is adjacent to the stop flange 112.
[0032] In this embodiment, the steam collecting hood 10 can be installed at the steam outlet of the steam cooker. At this time, the steam collecting cavity 13 is communicated with the inside of the steam cooker, and the steam generated by the steam cooker can enter the steam collecting cavity 13. The shape of the top plate 11 can be circular, square or triangular, and can be specifically designed according to the installation environment, which is not limited here. The shapes of the steam through hole 111 and the steam adsorption net disk 20 can be set to be circular, or can also be set to be square or triangular, etc. The steam adsorption net disk 20 is a three-dimensional porous structure, also called a three-dimensional network structure, for example, it can be three-dimensional graphene or three-dimensional honeycomb net, etc. The three-dimensional porous structure has a high porosity and a large amount of pore space inside, and can adsorb steam. The steam adsorption net disk 20 is located on one side of the steam through hole 111 in the steam collecting cavity 13. The steam flowing into the steam collecting cavity 13 can be intercepted and adsorbed by the steam adsorption net disk 20 when flowing towards the steam through hole 111. The steam can enter the pores of the steam suction net disk, and after cooling in the steam adsorption net disk 20, it is converted into liquid water. The liquid water can be thrown out by the rotating steam adsorption net disk 20 to the surrounding plate 12, and finally flows back to the steam cooker along the surrounding plate 12.
[0033] The stop flange 112 extends along the circumference of the steam hole 111. The stop flange 112 can be formed by processing separately and then connected to the periphery of the steam hole 111, or can be directly formed by folding the periphery of the steam hole 111 toward the steam collecting chamber 13, and there is no limitation here. Part of the steam will not flow directly to the steam hole 111 along the opening direction of the steam hole 111, but will first fall on the top plate 11, and then flow along the top plate 11 to the steam hole 111. This part of the steam will be stopped by the stop flange 112 and cannot flow out of the steam hole 111 directly, but needs to flow in a direction away from the top plate 11 to turn over the stop flange 112. Most of the steam will be converted into liquid water during the process of flowing along the stop flange 112, so the amount of steam that finally turns over the stop flange 112 can be greatly reduced, so as to effectively reduce the amount of steam flowing out of the steam hole 111.
[0034] Specifically, the steam adsorption mesh disk 20 includes nickel foam. The base material used is a porous open-cell foam plastic. The conductive layer can be prepared by three methods: chemical nickel plating, vacuum nickel plating, and impregnation with conductive glue (palladium sol, submicron graphite emulsion, etc.). After pre-nickel plating, thick nickel can be electroplated in a common sulfate nickel plating electrolyte, and then a three-dimensional network nickel foam material with excellent performance can be obtained through calcination, reduction, and annealing processes. The nickel foam is a three-dimensional network structure with high porosity, high specific surface area, and uniformity. The nickel foam has higher chemical stability, higher tensile strength and thermal shock resistance, is less susceptible to corrosion, and has a longer working life, so it can effectively extend the overall working life of the steam interception device.
[0035] In practical applications, the thickness of the steam adsorption net plate 20 is set to 10 mm to 20 mm, for example, it can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 9 mm or 20 mm, etc. Setting the thickness of the steam adsorption net plate 20 to 10 mm to 20 mm can not only ensure the adsorption capacity of the steam adsorption net plate 20 for steam, but also reasonably control the occupied space of the steam adsorption net plate 20 in the steam collecting chamber 13.
[0036] For example, Figure 2 As shown, the projection area of the steam adsorption net plate 20 on the top plate 11 is larger than the flow area of the steam through hole 111, and the projection of the stop flange 112 on the top plate 11 is located within the projection area of the steam adsorption net plate 20. In this way, the steam through hole 111 and the stop flange 112 can both be located within the covering area of the steam adsorption net plate 20, so that the steam adsorption net plate 20 can more fully intercept the steam flowing to the steam through hole 111, and further reduce the amount of steam emitting from the steam through hole 111.
[0037] The upper surface of the steam adsorption mesh disk 20 may abut against the stop flange 112 , or may form an anti-friction gap.
[0038] Specifically, as Figure 2 shown, a friction prevention gap is formed between the steam adsorption net disk 20 and the stop flanging 112. The friction prevention gap can prevent the steam adsorption net disk 20 from rubbing against the stop flanging 112 during rotation to generate noise. In this way, both the resistance received by the steam adsorption net disk 20 during rotation can be reduced, and the working noise of the steam interception device can be lowered.
[0039] In practical applications, the width of the friction prevention gap is less than or equal to 2 mm. In this way, the amount of steam escaping from the steam through hole 111 through the friction prevention gap can be reduced to ensure the use effect of the steam interception device.
[0040] The rotation of the steam adsorption net disk 20 can be manually driven or automatically driven by a driving electrical appliance.
[0041] Exemplarily, as Figure 1 and Figure 2 shown, the steam interception device further includes a driving device 30. The driving device 30 is installed on the upper surface of the top plate 11. The output shaft of the driving device 30 is connected to the steam adsorption net disk 20 to drive the steam adsorption net disk 20 to rotate. The driving device 30 can achieve the automatic driving of the steam adsorption net disk 20 to improve the use convenience of the steam interception device. In addition, the steam adsorption net disk 20 can also be suspended in the steam collecting cavity 13 near the steam through hole 111 through the output shaft of the driving device 30. The installation method is simpler and more convenient, and there is no frictional force during rotation. Installing the driving device 30 outside the steam collecting cavity 13 can avoid the driving device 30 occupying the internal space of the steam collecting cavity 13 and prevent the steam in the steam collecting cavity 13 from affecting the driving device 30.
[0042] Specifically, as Figure 1 and Figure 2As shown, the driving device 30 includes a driving motor 31 and a mounting bracket 32. The mounting bracket 32 includes a mounting plate 321 and two supporting parts 322. The two supporting parts 322 are respectively located on opposite sides of the steam through-hole 111 and are connected to the top plate 11. The mounting plate 321 straddles the steam through-hole 111, and both ends of the mounting plate 321 are respectively connected to the two supporting parts 322. The driving motor 31 is mounted on the mounting plate 321. The supporting parts 322 can separate a sufficient distance between the steam through-hole 111 and the mounting plate 321. The mounting plate 321 can be provided with mounting holes opposite to the steam through-hole 111, and the driving motor 31 is mounted in the mounting holes. In this way, the installation method of the driving device 30 can be simplified. The driving motor 31 is opposite to the central area of the steam through-hole 111. Even if steam leaks out of the steam through-hole 111 from the anti-friction gap, it will not directly flow towards the driving motor 31, thereby further reducing the influence of steam on the driving motor 31 and improving the operating stability of the driving motor 31.
[0043] Combined with the above embodiments of nickel foam, it is difficult for a steam adsorption mesh disk 20 made of a material similar to nickel foam to be directly fixedly connected to the output shaft. To solve this problem, in practical applications, as Figure 2 and Figure 3 shown, a limiting rib 33 protrudes from the peripheral wall of the output shaft. The driving device 30 further includes a first clamping plate 34, a second clamping plate 35 and a fixing sleeve 36. The first clamping plate 34 and the second fixing plate respectively overlap on opposite sides of the steam adsorption mesh disk 20. The output shaft sequentially passes through the first clamping plate 34, the steam adsorption mesh disk 20 and the second clamping plate 35. The limiting rib 33 abuts against the first clamping plate 34. The fixing sleeve 36 is sleeved on the end of the output shaft and presses against the second clamping plate 35 to clamp the steam adsorption mesh disk 20.
[0044] Both the first clamping plate 34 and the second clamping plate 35 are fixedly matched with the output shaft to rotate with the output shaft. The limiting rib 33 can play a limiting role on the first clamping plate 34, and the fixing sleeve 36 can play a pressing role on the second clamping plate, so that the steam adsorption mesh disk 20 can be clamped between the first clamping plate 34 and the second clamping plate 35, enabling the steam adsorption mesh disk 20 to rotate together with the first clamping plate 34, the second clamping plate 35 and the output shaft. External threads can be provided on the peripheral wall of the end of the output shaft, and internal threads can be provided on the inner wall of the fixing sleeve 36. The fixing sleeve 36 and the output shaft are in threaded cooperation, so that the sleeving position of the fixing sleeve 36 on the output shaft can be adjusted by rotation, that is, the distance between the first clamping plate 34 and the second clamping plate 35 can be adjusted, thereby adapting to steam adsorption mesh disks 20 of different thicknesses and improving the use effect of the driving device 30.
[0045] As Figure 4As shown in the figure, the present utility model also provides a steam cooker, which comprises a cooker body 40 and a steam interception device. The specific structure of the steam interception device refers to the above embodiments. Since this steam cooker adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the cooker body 40 is provided with a steam opening, the steam interception device is installed at the steam opening, and the interior of the cooker body 40 is communicated with the steam interception device through the steam opening.
[0046] The steam opening can be opened on the side wall of the cooker body 40 or on the top wall of the cooker body 40.
