Pressure cooking appliance 100 according to an embodiment of the present invention, specifically, pressure is described in detail below with reference to Fig. 1-Fig. 6
Cooking apparatus 100 is used for cooking food.Optionally, pressure cooking appliance 100 is electric pressure cooking saucepan.
As Figure 1-Figure 4, pressure cooking appliance 100 according to an embodiment of the present invention, including：Pot body 1, pot cover 2, cooling
Device 3 and fan 7.Wherein pot body 1 includes outer pot and interior pot, and interior pot is located in outer pot, it is to be understood that in food is placed on
It is cooked in pot, the heating device heated for internal pot is additionally provided between outer pot and interior pot.
Pot cover 2 is located at the top of pot body 1, and pot cover 2 is used to open or closes the cooking space in interior pot.Specifically, pot cover 2
It is detachably arranged in pot body 1.It is understood that also setting up the elements such as exhaust valve on pot cover 2, pressure cooking appliance 100 is also
The components such as including control device, the working principle of pressure cooking appliance 100 have been the prior art, here just without retouching in detail
It states.
Pot cover 2 includes bottom plate 20 and shell 21, and the spray space of bottom-open is limited in shell 21, and bottom plate 20 is located at outer
To cover spray space, shell 21 is equipped with air outlet 210 for the bottom of shell 21.When pot cover 2 is located in pot body 1 to close culinary art sky
Between when, bottom plate 20 be cooking space roof, bottom plate 20 be suitable for directly contacted with the environment in cooking space, to pass through reduction
The purpose for reducing the temperature in cooking space can be realized in the temperature of bottom plate 20.Preferably, bottom plate 20 is that metalwork is for example stainless
Steel part, so as to accelerate bottom plate 20 to the cooling effect of environment in interior pot.Optionally, shell 21 is plastic part to reduce into
This.
Cooling device 3 includes nozzle 30, water tank 31 and draw-out device 32, and nozzle 30 is located on shell 21 with towards bottom plate 20
Liquid is sprayed, water tank 31 is located on pot body 1 or pot cover 2, and water flow road 33, draw-out device are connected between water tank 31 and nozzle 30
32 are connected on water flow road 33 so that the liquid in water tank 31 is delivered to nozzle 30, and cooling device 3 is constructed such that from nozzle
30 liquid sprayed boil phase transformation on the base plate 20.
Specifically, by be arranged nozzle 30 number, the aperture of nozzle 30 and the power of draw-out device 32, can control from
The flow for the liquid that nozzle 30 sprays, to guarantee that sprinkling liquid on the base plate 20 can boil phase under the heat of bottom plate 20
Become.For example, existing electromagnetic pump PF40 and PF60, provides maximum pressure 4.8bar and 3.5bar respectively, if using PF40 electricity
Magnetic pumping, the single aperture 0.3mm nozzle 30, then enter spray space in fluid flow in 1.05ml/s；If used
PF40 electromagnetic pump, three apertures 0.3mm nozzle 30, then enter the fluid flow in spray space in 2ml/s.In the present invention
Preferred embodiment in, by control nozzle 30 number, the aperture of nozzle 30 and the type of draw-out device 32, will go into spray
The flow control of the liquid in space is drenched between 1ml/s-1.5ml/s.
In a specific embodiment of the present invention, the granularity of the liquid sprayed from nozzle 30 is in 50um-200um, further
Ground, the granularity of the liquid sprayed from nozzle 30 thereby may be ensured that the liquid contact sprayed from nozzle 30 in 50um-100um
It is immediately vaporized when to bottom plate 20.
Optionally, draw-out device 32 is water pump.Specifically, the liquid in water tank 31 is water.Optionally, water tank 31 is detachable
Ground is located on the periphery wall of outer pot, consequently facilitating the liquid in replacement and subsidiary water tank 31.
Fan 7 is located on shell 21 to dry in direction spray space.To which fan 7 can will spray the air in space
Blow to air outlet 210, the boil on the base plate 20 high-temperature steam of phase transformation generation of liquid accelerates under the action of fan 7 from air outlet
210 discharges improve the speed air flow in spray space, further increase cooling effect, shorten cooling time.
Specifically, when pressure cooking appliance 100 is cooked, pressure and temperature in interior pot rise, when completion is cooked
After preparing food, steam and coolant-temperature gage in interior pot are more than 100 DEG C, then needing for temperature to be reduced to can just uncap not higher than 100 DEG C.When interior
Temperature in pot is more than 100 DEG C, and the temperature on bottom plate 20 is also higher for example close to 100 DEG C.
Therefore after the completion of culinary art, draw-out device 32 is opened, draw-out device 32 is by the Liquid extracting in water tank 31 to nozzle
At 30, liquid is sprayed to bottom plate 20 by nozzle 30, and the temperature of bottom plate 20 makes the liquid boiling phase transformation for spraying to it, to utilize liquid
Latent heat of phase change take away heat, reduce the temperature of bottom plate 20 to reduce the temperature in interior pot, under the action of fan 7, after phase transformation
High-temperature gas accelerate from air outlet 210 be discharged pot cover 2 outside.Simultaneously because the coefficient of heat transfer of phase transformation reaches 10^6w/m2K, thus
It can be shortened cooling time.
Pressure cooking appliance 100 according to an embodiment of the present invention, by making the liquid sprayed from nozzle 30 in bottom plate 20
Upper boiling phase transformation, the heat of bottom plate 20 is taken away using the latent heat of phase change of liquid, can effectively reduce the temperature in interior pot to reach
To temperature of uncapping, while by accelerating the air in spray space to flow using fan 7, accelerate from the discharge of air outlet 210
Speed air flow, not only cooling rate is fast, realizes the purpose that fast cooling is uncapped, small with hourly water consumption, reduces cost.
As shown in Figure 1-Figure 3, in some embodiments of the invention, fan 7 is located at the center of the roof of shell 21, fan
Meet following relationship between 7 diameter D1 and the diameter maximum value D2 of shell 21：D1=(10%-50%) D2.So as to protect
The airflow effects of fan 7 are demonstrate,proved, cooling effect can be improved in guarantee.Preferably, D1=(20%-40%) D2.
According to a further embodiment of the invention, the distance between the center of nozzle 30 and the center of fan 7 L and bottom plate 20
Radius R between meet following relationship：L=(1/3-1) R.Preferably, L=(1/2-2/3) R.To guarantee what nozzle 30 sprayed
Liquid can be sprayed on bottom plate 20, avoid due to nozzle 30 and 7 hypotelorism of fan and liquid that nozzle 30 is sprayed without
Method reaches on bottom plate 20, ensure that cooling effect.
Further, nozzle 30 is multiple, substantially symmetrical about its central axis setting of multiple nozzles 30 relative to fan 7.Further
