Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment provides a steam cooking device, as shown in fig. 2, comprising a steam cooking device body 1, a steam generator 2, and a throttling and speed-increasing steam delivery component 3 for increasing steam pressure;
The embodiment is that the flow distance of the steam in the cooking cavity 11 is increased, so that the stay time of the steam in the cooking cavity 11 is increased, and the heat exchange efficiency is improved.
Because the throttling, accelerating and steam-conveying assembly 3 can increase the flow velocity of steam, and the steam generator 2 is communicated with the cooking cavity 11 through the throttling, accelerating and steam-conveying assembly 3, the flow velocity of the steam is increased after the steam generated by the steam generator 2 passes through the throttling, accelerating and steam-conveying assembly 3, and the steam can be sprayed into the cooking cavity 11 by the throttling, accelerating and steam-conveying assembly 3; the steam is sprayed into the lower part of the cooking cavity 11 and then automatically rises, and the steam outlet 13 is communicated with the upper part of the cooking cavity 11, so that the steam finally flows out of the cooking cavity 11 from the steam outlet 13;
in the present embodiment, the flow path of the steam in the cooking cavity 11 is as shown in fig. 3 and 4, and the steam is sprayed from the throttling and speed-increasing steam delivery assembly 3 and flows to the lower part of the cooking cavity 11 instead of floating on the upper part of the cooking cavity 11 (as shown in fig. 1); then, steam flows to the upper portion of culinary art chamber 11 again, flows out culinary art chamber 11 from steam outlet 13 at last, and the steam of this embodiment is far away at the distance that flows in culinary art chamber 11, and the dwell time is longer, and the heat exchange efficiency of steam obtains improving, and the heat utilization efficiency of steam improves, and then shortens the culinary art time.
In the specific embodiment, the throttling and speed-increasing steam delivery assembly 3 comprises a steam delivery pipe 31 and a nozzle 32; one end of the steam delivery pipe 31 is connected with the steam outlet of the steam generator 2, the other end is connected with the nozzle 32, and the nozzle 32 is positioned in the steam inlet 12 and communicated with the cooking cavity 11;
the steam generator 2 generates steam, the steam flows out from a steam outlet of the steam generator 2, enters the steam conveying pipe 31, passes through the nozzle 32, increases the flow velocity of the steam and is sprayed into the cooking cavity 11;
in this embodiment, the inner diameter of the nozzle 32 and the inner diameter of the steam pipe 31 are reduced abruptly in order to ensure that the steam is rapidly increased after passing through the nozzle 32, thereby ensuring that the steam can be injected into the lower portion of the cooking chamber 11.
Abrupt change means that the inner diameter of the nozzle 32 is much smaller than the inner diameter of the steam pipe 31, for example, the inner diameter of the steam pipe 31 is 8mm, the inner diameter of the nozzle 32 is smaller than half of the inner diameter of the steam pipe 31, and the inner diameter of the nozzle 32 is 3 mm.
In addition, because the inner diameter of the nozzle 32 is smaller than the inner diameter of the steam delivery pipe 31 and because the steam flow rate per unit time is not changed, according to the ideal gas state equation PV — nRT, the temperature of the steam increases, that is, the temperature of the steam passing through the nozzle 32 is increased compared with the temperature of the steam in the steam delivery pipe 31, so that not only the heat loss of the steam during the transmission process can be avoided, but also the temperature increase speed in the cooking cavity 11 can be rapidly increased, and the cooking time can be further shortened.
In the specific embodiment, the nozzle 32 is provided with an air inlet channel 321 and an air outlet channel 322 which are communicated with each other, and the inner diameter of the air outlet channel 322 is smaller than the inner diameter of the air inlet channel 321 and is reduced in a sudden manner.
Wherein reduced mutability means: for example, the inner diameter of steam inlet passage 321 is 8mm, and the inner diameter of steam outlet passage 322 is reduced directly to 4mm, or directly to 2mm, to ensure an increased steam flow rate through steam outlet passage 322.
The steam enters the nozzle 32 from the steam inlet passage 321 and then flows out of the nozzle 32 from the steam outlet passage 322; because the inner diameter of the steam inlet passage 321 is larger than that of the steam outlet passage 322, the speed of the steam flowing into the steam outlet passage 322 is lower than that of the steam flowing out of the steam outlet passage 322, that is, the speed of the steam sprayed into the cooking cavity 11 is higher than that of the steam flowing into the nozzle 32, so that the flow speed of the steam is further increased, the steam can be further ensured to move for a longer distance in the cooking cavity 11, and the residence time of the steam in the cooking cavity 11 is further increased;
in addition, because the flow velocity of the steam is increased by reducing the inner diameter of the steam flow, the pressure of the steam is correspondingly increased, and the temperature of the steam is correspondingly increased according to the ideal gas state equation.
In specific embodiment, the steam outlet of steam outlet channel 322 inclines towards the middle part below of cooking chamber and arranges, just so makes steam when colliding with the middle part bottom of cooking chamber mutually, and steam is by the bounce-back scattering in cooking chamber, fills about and space about the cooking chamber fast for steam is in the abundant heat transfer of cooking intracavity, promotes the programming rate in cooking chamber, and the homogeneity of cooking intracavity temperature.
In a specific embodiment, the inner diameter of the steam outlet channel 322 is 1.2 mm-3 mm; if the inner diameter of the steam outlet passage 322 is less than 1.2mm, a howling sound is generated when steam is injected; when the inner diameter of the steam outlet channel 322 is larger than 3mm, the injection angle of the steam and the moving distance of the steam in the cooking cavity become small, which is not beneficial to the steam to fill the cooking cavity rapidly.
In this example, the inner diameter of the steam outlet passage 322 is 2 mm.
In a particular embodiment, the inner diameter of the steam delivery pipe 31 is smaller than the inner diameter of the steam outlet of the steam generator 2;
since the inner diameter of the steam delivery pipe 31 is smaller than the inner diameter of the steam outlet of the steam generator 2 and the flow rate of the steam is not changed, the flow rate of the steam in the steam delivery pipe 31 is larger than the flow rate of the steam flowing from the steam generator 2 into the steam delivery pipe 31, and further, since the steam pressure is increased, the temperature of the steam in the steam delivery pipe 31 is also increased, which can prevent the heat loss during the steam delivery.
In this embodiment, the inner diameter of the steam outlet of the steam generator 2, the inner diameter of the steam delivery pipe 31, the inner diameter of the steam inlet passage 321, and the inner diameter of the steam outlet passage 322 are sequentially decreased, so that it is ensured that the temperature of the steam is gradually increased along with the decrease of the inner diameter during the steam delivery process, thereby avoiding the decrease of the temperature of the steam during the steam delivery process, and even the temperature of the steam sprayed from the steam outlet passage 322 is higher than the temperature of the steam generated by the steam generator 2, so as to further increase the temperature of the steam entering the cooking cavity 11.
In this embodiment, the inner diameter of the steam delivery pipe 31 and the inner diameter of the steam inlet passage 321 may be equal, and the inner diameter of the steam outlet of the steam generator 2, the inner diameter of the steam delivery pipe 31, and the inner diameter of the steam outlet passage 322 are gradually decreased.
In the specific embodiment, the inner diameter of the steam conveying pipe 31 is 5 mm-7 mm;
in this embodiment, the steam outlet of the steam generator 2 has an inner diameter of 10mm, the steam pipe 31 has an inner diameter of 6mm, and the steam outlet channel 322 has an inner diameter of 2 mm.
In a particular embodiment, steam inlet 12 and steam outlet 13 are both located above cooking chamber 11; this is to further increase the residence time of the steam inside the cooking chamber 11; steam is injected from the upper steam inlet 12 of the cooking cavity 11 to the lower part of the cooking cavity 11, and then the steam moves upwards and flows out of the cooking cavity from the steam outlet 13 at the upper part of the cooking cavity 11, so that the moving distance of the steam in the cooking cavity 11 is increased, the staying time of the steam in the cooking cavity 11 is further increased, and the heat exchange efficiency is improved.
In the specific embodiment, one side of the top plate of the steam cooking device body 1 is provided with a steam inlet 12, and the other side of the top plate far away from the steam inlet 12 is provided with a steam outlet 13; i.e. to increase the distance between the steam inlet 12 and the steam outlet 13 as much as possible, in order to increase the movement distance of the steam inside the cooking chamber 11.
In the present embodiment, the steam inlet 12 is located at the rear of the top plate of the steam cooking apparatus body 1, and near the rear edge; and the steam outlet 13 is positioned at the front part of the top plate of the steam cooking device body 1 and close to the front edge; the purpose of this design is to maximize the spacing between the steam inlet 12 and the steam outlet 13, and thus increase the residence time of the steam within the cooking chamber 11.
In a specific embodiment, the number of the steam inlets 12 is at least one, for example, 2, 3, etc.; in this embodiment, the number of the steam inlets 12 is two, and the two steam inlets 12 are respectively located at the left and right ends of the top plate of the steam cooking device body 1, so that when steam enters the cooking cavity 11, the spraying area of the steam is wider, and the cooking cavity 11 can be filled with the steam quickly.
In the embodiment, the steam generator 2 can be a steam boiler, which is installed on the top plate of the steam cooking device body 1 and is communicated with the cooking cavity 11 through the throttling, speed-increasing and steam-conveying assembly 3; in this embodiment, the steam inlet 12 is also located on the top plate of the steam cooking device body 1, so that the transmission distance of the steam entering the cooking cavity 11 can be reduced, and the heat loss can be avoided.
The working process is as follows:
the steam cooking device is started, the steam generator 2 generates steam, and because the steam generator 2 is communicated with the cooking cavity 11 through the throttling and speed-increasing steam transmission assembly 3, the steam flows out from a steam outlet of the steam generator 2, enters the steam transmission pipe 31 of the throttling and speed-increasing steam transmission assembly 3, enters the steam inlet channel 321 of the nozzle 32, finally flows out from the steam outlet channel 322 of the nozzle 32 and is sprayed into the lower part of the cooking cavity 11;
because the inner diameter of the steam transmission pipe 31 in the embodiment is smaller than the inner diameter of the steam outlet of the steam generator 2, the steam is pressurized and accelerated for the first time after flowing into the steam transmission pipe 31; because the inner diameter of the steam outlet channel 322 is smaller than that of the steam inlet channel 321, the steam is pressurized and accelerated for the second time after flowing into the steam outlet channel 322; after the steam is pressurized and accelerated twice, the flow rate of the steam sprayed out of the steam outlet channel 322 is large, so that the steam can move to the lower part of the cooking cavity 11 as far as possible after entering the cooking cavity 11 and even reach the bottom of the cooking cavity 11, and the downward moving distance of the steam is increased; because the steam outlet 13 is positioned above the steam cavity 11, the steam in the cooking cavity 11 still moves from bottom to top to the steam outlet 13 and then flows out of the cooking cavity 11, so that the upward movement distance of the steam is increased, and the retention time of the steam in the cooking cavity 11 is increased;
in addition, because the temperature of the steam is increased after the steam is pressurized and accelerated for the second time, the temperature of the steam can be effectively prevented from being reduced in the transmission process, and even the temperature of the ejected steam is higher than the temperature of the steam generated by the steam generator 2, so that the temperature rising speed in the cooking cavity 11 is further accelerated, and the cooking time is further shortened.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
