Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Embodiment 1, see that Fig. 1 and Fig. 2, the present invention are provided with water-stop ditch 11 in the pot 1 boiling the ball of glutinous rice, and set up pot cover unit；This pot cover unit includes pot cover 2, water container 4, many root posts 3, plunger 51, plunger compartment 52, spring 53, mozzle 55, pneumatic tube 56, water-retention basin 6, three breathers 7, suction tube 8, Venturi tubes 10；Pot cover 2 is connected with water container 4 by many root posts 3, and the lower end of pot cover 2 is inserted in the water-stop ditch 11 in pot 1, and water-stop ditch 11 is provided with water for sealing (this water being used for sealing is usually normal-temperature water, certain temperature height or the low water of temperature can also)；Described water container 4 is provided with normal-temperature water.Plunger 51, plunger compartment 52, spring 53, mozzle 55, pneumatic tube 56 and water-retention basin 6 are set between water container 4 and pot cover 2；The perpendicular shape in plunger compartment 52, and parallel with Venturi tube 10, pneumatic tube 56, breather 7, the lower end of plunger compartment 52 connects one end of suction tube 8, and the other end of suction tube 8 is positioned at Venturi tube 10, and the port of suction tube 8 flushes with the thinnest place in Venturi tube 10；The upper end of plunger compartment 52 connects one end of three breathers 7, and the other end of breather 7 is positioned at water container, and higher than water container 4.The side of upper end, plunger compartment 52 and one end vertical connection of mozzle 55, the other end of mozzle 55 and pneumatic tube 56 vertical connection；The upper end of pneumatic tube 56 is positioned at water container 4, and higher than water container 4, the lower end of pneumatic tube 56 connects water-retention basin 6, and the lower end of water-retention basin 6 connects a spiral segment flow tube 9, and this spiral segment flow tube 9 enters in pot 1 through pot cover 2；Water container 4 is connected with plunger compartment 52 by water inlet 54；Plunger 51 top is provided with the needle-like bolt 511 that can block water inlet 54.
The effect of pneumatic tube 56 is in that to make water-retention basin 6 connect with external atmosphere pressure so that the normal-temperature water in water-retention basin 6 can pass through spiral segment flow tube 9 and flow in pot 1.
The reason arranging three breathers 7 is the end face making atmospheric pressure be evenly distributed on plunger 51.If only arranging a breather 7, plunger 51 side stress causes that it tilts, the difficulty so that plunger 51 is advanced in plunger compartment 52.
The effect of spiral segment flow tube 9 is in that the normal-temperature water in restriction water-retention basin 6 is too quickly in pot 1, because if the water temperature in pot 1 declines rapidly, the steam of ejection will disappear in the short time, needle-like bolt 511 can block water inlet 54 prematurely, so can cause entering the room temperature water shortage in water-retention basin 6, and enter the room temperature water shortage in pot 1, can cause that ball of glutinous rice outer layer can not get suitable cooling, so that the outer layer of the ball of glutinous rice is easily broken.
In order to ensure that the normal-temperature water at water container 4 and water-retention basin 6 is not conducted heat by pot cover 2, therefore arranging heat insulation 21 with pot cover 2 contact position, and water container 4 and water-retention basin 6 can preferentially adopt the material that heat conductivility is bad.
Using method: the ball of glutinous rice to be boiled are put in the boiling water of pot 1 (under normal circumstances, if it is A that the volume of the ball of glutinous rice to be boiled is converted into volume, then the boiling water volume in pot should be 4 times of A, the ball of glutinous rice so just can be made will not to be sticked together in boiling), the water in pot 1 obtains cooling and stops boiling；Stir the ball of glutinous rice with spoon, make the ball of glutinous rice not sticky end be evenly distributed in the water in pot 1；Then water-stop ditch 11 in pot 1 adds the water for sealing；And pot cover unit is placed on pot 1, the lower end of pot cover 2 is inserted in the water-stop ditch 11 in pot 1, adds normal-temperature water in water container 4；When the water in pot 1 is heated continuously to boiling；Enter and automatically add the normal-temperature water stage:
Owing to the water blocking in water-stop ditch 11 has lived the gap between pot 1 and pot cover 2, Venturi tube 10 is all rapidly entered in the steam being collected in pot 1, the air-flow velocity the most carefully located through Venturi tube 10 becomes big more, according to Venturi effect, air-flow velocity strengthens, pressure decreases, the pressure that Venturi tube 10 is the most carefully located is much smaller than atmospheric pressure, therefore negative pressure is formed in suction tube 8, external atmosphere pressure acts on plunger 51 by three breathers 7, plunger 51 overcomes spring 53 elastic force, moves down, and the needle-like bolt 511 on plunger 51 leaves water inlet 54；At this moment, the normal-temperature water in water container 4 is from water inlet 54, and through plunger compartment 52, mozzle 55, pneumatic tube 56 arrived in water-retention basin 6, and slowly entered in pot 1 by spiral segment flow tube 9；Until the water-cooled in pot 1 but stops boiling to a certain extent；Steam reduces, until disappearing, the pressure that Venturi tube 10 is the most carefully located becomes big, the external world disappears with pressure difference in Venturi tube 10, negative pressure in suction tube 8 also disappears, and by plunger 51 upwardly, the needle-like bolt 511 on last plunger 51 has blocked water inlet 54, and (plunger 51 is in travelling upwardly for the elastic force of spring 53, clamp-oning in water container 4 by water inlet 54 by a part of normal-temperature water in plunger compartment 52, another part normal-temperature water can be squeezed in 3 breathers 7 and mozzle 55)；Normal-temperature water in mozzle 55, pneumatic tube 56 and water-retention basin 6 continues through spiral segment flow tube 9 and flows in pot 1, the water temperature continuous decrease in pot 1；Until the normal-temperature water in water-retention basin 6 and spiral segment flow tube 9 all flows in pot 1；In entering the process automatically adding the normal-temperature water stage, the water in pot 1 is heated continuously always；Then, the boiling again of the water in pot 1；
Hereafter, automatic gradation priming apparatus repeats above-mentioned entrance and automatically adds the operation in normal-temperature water stage；
After third time adds normal-temperature water, treat the water boiling in pot 1, so that it may in pot 1, the water of boiling pulls the ball of glutinous rice boiled out.
Without pulling the ball of glutinous rice boiled in time out, also without relation, because automatic gradation priming apparatus can repeatedly repeat above-mentioned entrance and automatically add the operation in normal-temperature water stage, namely timing adds normal-temperature water in pot 1, so that ensureing that the outer layer of the ball of glutinous rice does not break because of overdone.
This device method for designing:
Design object is the unpowered priming apparatus that boiling is converted into the ball of glutinous rice that volume is A,
More than 10 times that in pot, water-stop ditch is A with the dischargeable capacity of lower part；
The total measurement (volume) of water-retention basin and spiral segment flow tube is A；
Bore and the length of run of spiral segment flow tube are it is ensured that the water that the water yield must be had to be A within 15 second time is flowed in pot from water-retention basin by spiral throttle pipe；
The bore of water inlet, mozzle and pneumatic tube should be greater than the bore of spiral segment flow tube, and before guaranteeing that the water in water-retention basin is flowed in pot by spiral throttle pipe, water-retention basin and spiral segment flow tube have been filled with normal-temperature water.
The illustration of above-mentioned method for designing: design object is that to be converted into volume A by volume be 400 milliliters of (quick-freezing or existing system) ball of glutinous rice in boiling, (actually the 300-500 milliliter ball of glutinous rice can boiling, what take here is intermediate value)
Below water-stop ditch more than dischargeable capacity is A 10 times in pot, namely more than 4000 milliliters:
Dischargeable capacity in pot 1, refers to the space of the actual boiling ball of glutinous rice of water-stop ditch less than 11 in pot 1.It is calculated as follows:
Initially boil 4 times of 400 milliliters of water of the ball of glutinous rice, namely 1600 milliliters.Plus the volume of the ball of glutinous rice itself, two amount to 2000 milliliters.
Add three normal-temperature water, i.e. 3 times of 400 milliliters, count 1200 milliliters.
Because this device is automatically to add water, person's imprudence is forgotten boiling the thing of the ball of glutinous rice on stove sometimes to boil the ball of glutinous rice, so the dischargeable capacity in pot should leave the space of twice interpolation normal-temperature water, i.e. and 2 times of 400 milliliters, count 800 milliliters.
Above-mentioned add up to 4000 milliliters, namely need to consider more than dischargeable capacity is A 10 times in pot below water-stop ditch in the design；
The total measurement (volume) A of water-retention basin 6 and spiral segment flow tube 9 is 400 milliliters (owing to pneumatic tube 56 and mozzle 55 volume are little, therefore this volume of two is negligible):
Flow out spiral segment flow tube 9 enters the amount of the normal-temperature water in pot to the amount of above-mentioned 400 milliliters of water exactly, also it is simultaneously that total volume of water-retention basin 6 and spiral segment flow tube 9 is (if the total volume of water-retention basin 6 and spiral segment flow tube 9 is excessive, once the needle-like bolt 511 on plunger 51 does not block water inlet 54, just have too much normal-temperature water and flow into water-retention basin 6 and spiral segment flow tube 9, and then be flowed in pot 1).
Bore and the length of run of spiral segment flow tube 9 are it is ensured that the water that the water yield must be had to be A within 15 second time is flowed in pot 1 from water-retention basin 6 by spiral segment flow tube 9:
If normal-temperature water excessively slowly enters in pot 1 in the water of boiling, the boiling water in pot 1 cannot cool down in the short time, does not also just have the effect of cooling ball of glutinous rice outer layer.So the water that the water yield must be had to be A in 15 second time is flowed in pot 1 from water-retention basin 6 by spiral segment flow tube 9；
The bore of water inlet 54, mozzle 55 and pneumatic tube 56 should be greater than the bore of spiral segment flow tube 9, and before guaranteeing that the water in water-retention basin 6 is flowed in pot 1 by spiral segment flow tube 9, water-retention basin 6 and spiral segment flow tube 9 have been filled with normal-temperature water.
The effect of spiral segment flow tube 9 is in that to delay normal-temperature water to enter the time in pot 1, makes water inlet 54, mozzle 55 and pneumatic tube 56 have time enough that the normal-temperature water required for the cooling ball of glutinous rice is flowed into water-retention basin 6.Without spiral segment flow tube 9, the normal-temperature water that water-retention basin 6 flows out directly contacts the water of boiling in pot 1, boiling degree will weaken at once, the impulse force that steam produces also just weakens, act on the pressure difference on plunger 51 will reduce, spring 53 will promote the needle-like post 511 on plunger to block water inlet 54 at once, there will be no water to enter water-retention basin 6；And measure few normal-temperature water and will be unable to make the outer layer of the ball of glutinous rice to be cooled down fully, cause that ball of glutinous rice outer layer is overdone and breaks.
Producer can according to the size of the related components such as pot, water-retention basin and spiral segment flow tube, it is stipulated that boils the water of the ball of glutinous rice and the amount of the ball of glutinous rice, enables users to successfully boil according to description the ball of glutinous rice.
Embodiment 2, the mode (because being prior art, do not draw) that can seal with high-pressure cooker sealing ring, replace in embodiment 1 with the sealing means of water-stop ditch.Rubber seal is namely set between pot cover and pot.
