Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment provides a kind of controlled steam generating device, as shown in Figure 1, including closed feed water heater 1, interior
Formula heating member 2, water tank 3, pressure sensor 4 are set, the built-in heating part 2 is arranged in closed feed water heater 1, the water tank 3
It is connected to by the first sealing valve 31 with closed feed water heater 1, the outside of 1 upside of closed feed water heater is arranged in the pressure sensor 4
And it is connected to in closed feed water heater 1, the top of the closed feed water heater 1 is provided on venthole 11 and the venthole 11
It is provided with the second sealing valve 111.
It further, further include temperature sensor 5, the temperature sensor 5 is arranged at the bottom in closed feed water heater 1
Portion.
The temperature sensor 5 is fixed on the bottom of closed feed water heater 1, slightly above water level minimum point；When water level decreasing mistake
Low, temperature sensor 5 can generate temperature inflection point because of the thermally conductive temperature of metal (temperature is slightly above boiling point when having water)；Monitor temperature
Sealing valve is opened after inflection point immediately to fill the water to closed feed water heater 1.
It further, further include preheating water tank 6, the water tank 3 is connected to by the first sealing valve 31 with preheating water tank 6, institute
Preheating water tank 6 is stated to be connected to by third sealing valve 61 with closed feed water heater 1.
Water is carried out by metal heat-conducting to be preheating to boiling point in the preheating water tank 6, in this way, working as preheating water tank 6 to sealing
When heater 1 supplies water, due to the almost equality of temperature of the water in preheating water tank 6 and closed feed water heater 1, toward plus will not be because of during water
Water temperature reduces and interrupts quantity of steam supply.
Behind all supply closed feed water heater 1 of the water in the preheating water tank 6, third sealing valve 61 is closed, and open
First sealing valve 31, the water in water tank 3 are flowed into preheating water tank 6.
Further, further include controller, the controller respectively with built-in heating part 2, pressure sensor 4, temperature
Sensor 5, the first sealing valve 31, the second sealing valve 111, third sealing valve 61 connect.
The built-in heating part 2 is heating wire.
A nozzle is set in the venthole 11.
The control flow of the utility model embodiment, as shown in Fig. 2, being realized by following steps:
Step 101: being determined by the aperture of pressure sensor 4 and venthole 11 and spray the total of steam in closed feed water heater 1
Injection flow；
Specifically, according to the calculation formula of pressure and flowDetermine spray in closed feed water heater
Total injection flow q of steam out；It is that current pressure P, q in closed feed water heater is that wherein d, which is nozzle diameter, P in venthole,
Total injection flow, n are nozzle number, u is nozzle efficiency coefficient.
Step 102: the case where determining current culinary art demand quantity of steam；
Step 103: when a large amount of steam of the demand of culinary art, the built-in heating part 2 increases power and makes closed feed water heater 1
Interior pressure rises to first pressure P1；
Step 104: when a small amount of steam of the demand of culinary art, the built-in heating part 2 reduces power and makes closed feed water heater 1
Interior pressure is down to second pressure P2.
Specifically, the first pressure P1, second pressure the P2 mouthfeel according to required by cooking certain food and effect are pre-
It is configured after first passing through measurement.
For example, culinary art sponge cake, needs the air pressure in one two minutes of quick heating with full power to maintain P1 and quickly allows food when initial
Object heating；To make to be transferred to suitable low and middle-grade pressure P2 after the soft mouthfeel of sponge cake.
Further, further includes: it is needed during the cooking process in the steam of sometime discharging certain amount, it is described built-in
Formula heating member 2, which increases power, makes pressure in closed feed water heater 1 reach third pressure P3, when that time arrives, it is close to open second
It seals valve 111 and steam is discharged by venthole 11, and determine the discharge rate of steam by integrating to instantaneous quantity of steam, as the row of steam
Output closes the second sealing valve 111 when reaching fixed amount.
Specifically, according toDetermine the discharge rate of steam；Wherein, F (P) is pressure and instantaneous quantity of steam letter
Number, discharge rate of the instantaneous quantity of steam for instantaneous steam, i.e., total injection flow q,dt
For a kind of representation of time integral, indicate unit time member, A, B be respectively integral calculation initial time point and at the end of
Punctum.
In the exhaust process of the venthole 11, the third sealing valve 61 is in close state.
Further, further includes: when temperature sensor 5 detects that the temperature change in closed feed water heater 1 is too fast, open
Third sealing valve 61, water in preheating water tank 6 are judged in preheating water tank 6 because gravity flows in closed feed water heater 1 by the time
Third sealing valve 61 is closed after water flow is complete.
Specifically, when temperature sensor 5 detects that the temperature change in closed feed water heater 1 is too fast, heated sealed is determined
Water in device 1 will evaporate；Third sealing valve 61 is opened at this point, passing through, the water in preheating water tank 6 flows to sealing because of gravity
In heater 1, since almost equality of temperature will not be because of water temperature during toward water is added for the water in preheating water tank 6 and closed feed water heater 1
It reduces and interrupts quantity of steam supply.
The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model
Range.
