Background

At present, the cooking process of food is a common food processing procedure, and a cooking pan is the most common cooking processing equipment, and the cooking process mainly utilizes high-temperature steam to realize heating. Experiments have shown that the relationship between the liquefaction temperature of a gas and the temperature is non-linear. The number of increased pressures required per 1 ℃ rise is greater with increasing liquefaction temperature. When the liquefaction temperature rises above a certain value, the gas does not liquefy, no matter how the pressure is increased, the value of this temperature is called the critical temperature, and the minimum pressure at which the gas is at the critical temperature, at which the gas can liquefy, is called the critical pressure. For example, the critical temperature of water vapor is 374.5 ℃ and the critical pressure is 22.1 MPa. At present, the temperature of frying is generally 100-200 ℃, so that the temperature provided by the steam is far higher than that of conventional frying under proper pressure.

This patent supplies steam to multiunit cooking pot independently respectively to satisfy the use of independently cooking, multiunit cooking pot can separately cook food, and it just can continuously cook food as long as stagger cooking of cooking pot cooks food, can not appear food and cook inhomogeneous phenomenon, avoids appearing food overcooked phenomenon, cooks food effect very well.

Wherein the water smoke steam that the atomizing pipe 41 spun can be for carrying on the high temperature high pressure steam that obtains after the secondary heating, also can be the direct spun condensed water smoke that condensate recovery unit 4 retrieved, and its main function is in order to adjust the temperature and the pressure value of steam in main steam chamber 11 and the inferior steam chamber 12, realizes individualized local control steam temperature, and the pot body 2 that main steam chamber 11 and the corresponding inferior steam chamber 12 of being convenient for can realize different culinary art requirements. The pot body 2 can be a frying pot, a conventional open pot, a pressure cooker and the like in the application, and is designed according to the use requirement.

In a modified embodiment of the present application, in order to achieve better atomization of the condensed water, the water mist sprayed from the atomizing pipe 41 can be quickly and uniformly mixed with the high-temperature steam in the primary steam chamber 11 and the secondary steam chamber 12, and thus, the occurrence of too large local temperature difference is avoided. One of atomizing pipe 41 and main steam chamber 11 and inferior steam chamber 12 intercommunication is served and is provided with atomizing head 42, atomizing head 42 includes major structure 421, sets up orifice 422 and block 423 in major structure 421, the major structure 421 cartridge is on atomizing pipe 41's tip, be provided with in the major structure 421 and overflow passageway 424, the outside one end of major structure 421 is provided with a plurality of orifices 422 that the intercommunication overflowed passageway 424, the outside one end of major structure 421 is located orifice 422 spun one end and is opened there is atomizing chamber 425, block 423 cover dress is on atomizing chamber 425 open-ended one side. The effect of the barrier net 423 is mainly to form an intercepting net at one end of the atomizing cavity 425, which is open outwards, so that the high-speed water flow sprayed from the spraying holes 422 collides with the barrier net 423, and only a small part of water drops meeting the mesh specification of the barrier net 423 can pass through the barrier net 423, thereby achieving the effects of separating and dispersing the high-speed water flow and ensuring that the atomizing effect of the condensed water is better. Meanwhile, due to the blocking effect of the blocking net 423, the atomizing cavity 425 enables a part of high-speed water flow sprayed by the spraying holes 422 to be rebounded to collide with each other, so that a high-pressure water mist environment is formed, water drops meeting the mesh number specification of the blocking net 423 in the atomizing cavity 425 are further forced to be sprayed outwards, the water drops are formed into water drops with smaller particle sizes by the blocking net 423 twice or repeatedly, and a more efficient atomizing effect is achieved. The design enables the condensed water to be rapidly mixed with flowing high-temperature or low-temperature steam, and then the temperature and the pressure of the steam are improved.

In order to improve the effect of secondary atomization, the aperture of the mesh holes on the barrier net 423 is smaller than that of the jet holes 422, and the design mainly considers that if the condensed water jetted by the jet holes 422 is crushed only by the impact of the barrier net 423, obviously, the requirement cannot be met. If the aperture of the meshes on the barrier 423 is smaller than the aperture of the jet holes 422, condensed water sprayed by the jet holes 422 can collide with the meshes on the barrier 423 more easily, so that the collision rate is improved, and the aperture of the meshes on the barrier 423 is smaller than the aperture of the jet holes 422, so that a high-pressure atomizing cavity 425 structure is formed more easily, and the particle condensed water trapped in the atomizing cavity 425 can penetrate through the meshes of the barrier 423 to enter the main steam cavity 11 or the secondary steam cavity 12 under high-pressure reverse osmosis. In the present application, the mesh number of the barrier net 423 may be 200 to 1500 mesh, and particularly, the barrier net 423 with 300 to 600 mesh may be selected, and the barrier net 423 itself may be made of a high temperature resistant metal material or a high temperature resistant inorganic material, such as nickel-based alloy, Cr — Mo steel system, tungsten steel, etc., and the barrier net made of 12Cr1MoV material, which is cheap and easy to process, is preferred in the present application.

Referring to fig. 3 and 4, in a preferred embodiment, in order to achieve automatic control of the spray and better atomization effect, the atomizing head 42 further includes a solenoid device 42d and a valve body, the valve body is disposed in the flow passage 424 and is used for isolating or communicating the water inlet side and the water outlet side of the flow passage 424; the solenoid arrangement 42d is disposed outside the crossover passage 424; the valve body comprises a limiting sleeve 427, a spring 428, a valve core 429 and a valve seat 42a with a through hole, the limiting sleeve 427 is installed in the overflowing channel 424, a step 42b is arranged in the limiting sleeve 427, the valve core 429 is movably inserted in the limiting sleeve 427, the valve seat 42a is installed at one end, close to the water outlet, of the overflowing channel 424, and a steel ball 42c for plugging the through hole is arranged on the valve seat 42 a; one end of the spring 428 is abutted against the step 42b, the other end is abutted against the valve core 429, the spring 428 can force the valve core 429 to be abutted against the steel ball 42c to drive the steel ball 42c to block the through hole on the valve seat 42a, and the electromagnetic coil device 42d can force the valve core 429 to reciprocate along the axial direction of the limiting sleeve 427.

In the present application, an end of the flow passage 424 away from the nozzle hole 422 is provided with a water inlet, which is connected with the atomizing pipe 41. The electromagnetic coil device 42d comprises an electromagnetic coil and an iron core arranged on the inner side of the electromagnetic coil, the electromagnetic coil device 42d is cylindrical as a whole, and an electrode plate communicated with the electromagnetic coil is further arranged on the main body structure 421, so that the electromagnetic coil device is convenient to connect with an external power supply.

In the normal blocking state, the pressing force of the spring 428 will be against the steel ball 42c, and the pressing force of the spring 428 is mainly provided by the limiting sleeve 427, so that in practical use, how to make the limiting sleeve 427 have an action force in the flow passage 424, the present application uses the solenoid device 42d to apply an action force to the limiting sleeve 427, so that the limiting sleeve 427 can press or release the pressing force to the spring 428 in the flow passage 424. In order to better drive the position-limiting sleeve 427, in another embodiment of the present application, a silicon plunger is disposed on an end of the spool 429 away from the valve seat 42a, and the electromagnetic coil device 42d can force the silicon plunger to slide the position-limiting sleeve 427 along the flow passage 424, so as to release the spool 429 or press the steel ball 42c more heavily.

The working principle of the whole sprinkler is as follows: under the set action, the through hole is in a normally closed state, that is, even if there is no downward positive magnetic field, because the limiting sleeve 427 has an interaction force in the flow passage 424, the spring 428 has a certain precompression force, and the effect of blocking the through hole by pressing the steel ball 42c can be realized by the precompression force. Of course, there is also a case of using electromagnetic action for control, that is, after the atomizer 42 receives an external electromagnetic signal, the electromagnetic coil device 42d is operated, and how to operate the electromagnetic coil device to see the specific electromagnetic signal, that is, the electromagnetic coil device 42d forms a downward magnetic field or an upward magnetic field, in this application, assuming a downward positive magnetic field, the silicon iron core is forced to press the limiting sleeve 427 downward under the action of the downward magnetic field, so as to compress the spring 428, and the steel ball 42c blocks the through hole on the valve seat 42a, and at this time, water is not sprayed. In any case, the through hole can be plugged without spraying water. When water needs to be sprayed, the electromagnetic coil device 42d is switched on by reverse current, the electromagnetic coil device 42d forms an upward magnetic field, the limiting sleeve 427 is acted by an upward acting force, namely, the limiting sleeve 427 moves along the water inlet direction of the overflowing channel 424, the limiting sleeve 427 gradually loses the pressing force on the spring 428, so that the steel balls 42c on the through holes are loosened, at the moment, condensed water in the overflowing channel 424 can pass through the through holes to enter the water outlet end of the overflowing channel 424, the condensed water enters the atomizing cavity 5 through the spray holes 422 to realize secondary atomization, and finally passes through the barrier net 423 to enter the main steam cavity 11 or the secondary steam cavity 12. When the electromagnetic coil device 42d is powered off or reverse current is turned on, the limiting sleeve 427 is forced to move downward and press the spring 428, so as to force the steel ball 42c to block the through hole, thereby realizing no water spraying.

Generally, the steam generator 3 can only raise saturated steam with a temperature and a pressure, so that the steam flowing to the secondary steam chamber 12 does not meet the temperature requirement of the desired cooking after the primary steam chamber 11 is used, and for this reason, in a modified embodiment of the present application, the atomizing head 42 is provided with a heating wire 426 inside the atomizing chamber 425, and the heating wire 426 is provided on the inner wall of the atomizing chamber 425. The electric heating wire 426 is used to heat the water mist in the atomizing chamber 425, so that the water mist can provide a high-pressure and high-temperature water vapor, and the temperature of the steam in the corresponding secondary steam chamber 12 can be improved to meet the corresponding cooking requirement. Of course, in the present application, the heating wire 426 may be added to the atomizing head 42 corresponding to all the steam chambers, rather than to the atomizing head 42 corresponding to the secondary steam chamber 12. When the steam cooker is used, the atomized condensed water can be steam with higher temperature or the temperature of the condensed water is lower than that of the steam in the main steam cavity 11 or the secondary steam cavity 12, and the design can meet the personalized cooking requirements of the main steam cavity 11 and the secondary steam cavity 12.

Referring to fig. 3, in a modification of the above embodiment, the condensate recovery device 4 further includes a pumping pump 43 and a holding water tank 44, the pumping pump 43 is installed outside the holding water tank 44, and the output end of the pumping pump is communicated with the atomizing pipe 41, and bottoms of the primary steam cavity 11 and the secondary steam cavity 12 are communicated with the holding water tank 44 through a drain pipe 45.

For convenience of adjustment and control, a pressure adjusting knob 15 is disposed on the cooking bench 1, and the pressure adjusting knob 15 is electrically connected to a pressure adjusting valve 33 to control the pressure of the steam generator 3 discharged to the steam pipe 31.

Referring to fig. 1, 2 and 5, in practical use, steam in a conventional steam stove directly passes through the bottom of a pot body 2 to realize heat exchange; because the steam flow speed is fast, the whole heat exchange efficiency is not high, the heat energy of the steam is wasted more, and a part of high-temperature steam still has time to transfer heat and is conveyed to the bottom area away from the pot body 2. For this purpose, in one embodiment of the present application, the output end of the steam pipe 31 is disposed at the middle lower part of the primary steam cavity 11 and the secondary steam cavity 12, and the outlet direction is toward the bottom of the pot body 2; a plurality of steam guide convex patterns 21 are arranged in the region where the back surface of the pot body 2 is matched with the main steam cavity 11 and the secondary steam cavity 12, the steam guide convex patterns 21 are obliquely and downwards protruded, and a plurality of lines 22 for steam flowing are formed between two adjacent groups of steam guide convex patterns 21; the recovery pipe 32 is disposed on the upper side walls of the primary steam chamber 11 and the secondary steam chamber 12. When the steam pipe 31 sprays high-temperature steam to the bottom of the pot body 2, the high-temperature steam diffuses and flows along the grains 22 on the back surface of the bottom of the pot body 2, so that the whole high-temperature steam has enough time to contact with the back surface of the pot body 2 and conduct heat. In addition, in order to facilitate the flow of the high-temperature steam, the pan body 2 is a cambered pan, but in some embodiments, the pan can be a pan type, and only the contact time of the high-temperature steam with the back surface of the pan bottom is shorter than that of the cambered pan. In addition, because high temperature steam is from the bottom to the back blowout of pot body 2 of upper portion for high temperature steam flow can be diffused along the line 22 on the bottom of a boiler back along pot body 2 after the back contact with pot body 2, is favorable to high temperature steam to condense, releases the heat.

Because the pan edge of the conventional pan body 2 radiates heat outwards, in one embodiment of the present application, how to recover part of the heat of the pan edge by using the heat exchange pipeline 17 is utilized, so as to improve the use efficiency of energy. Meanwhile, the heated water in the water replenishing tank 16 can reduce the heat required by the steam generator 3, thereby achieving the effect of energy conservation.

The wireless coupling of the power supply coil 23 and the power receiving coil 51 can provide electric energy for the whole pot body 2, so that the intelligent control of the control panel 53 is facilitated. In practical use, since the whole cooking bench 1 has a plurality of cooking positions, if the control panel 53 is disposed on the cooking bench 1, the control panel is easily scratched, and at the same time, the control panel 53 and other electronic components are disposed in the pot cover 5, so as to facilitate the control of the steam generator 3 and the condensate water recovery device 4.
