Abstract

The utility model relates to a multifunctional overlap pressure cooker, which is characterized in that more than one layer of an auxiliary cooker is additionally arranged between a main cooker body and a cooker lid; the bottom end of the auxiliary cooker is connected with a connecting lid; the bottom part of the auxiliary cooker is fixed with a vent tube; a unidirectional auxiliary pressure valve is arranged in the vent tube. Because the unidirectional auxiliary pressure valve is arranged in the utility model, the switching-on threshold value for each layer of the unidirectional auxiliary pressure valve is set appropriately to satisfy the requirements of different pressure or time for cooking foods. The utility model has the advantages of time saving and energy saving. At the same time, the utility model removing the connecting lid and each cooker which is added with the existing pressure cooker lid, can respectively be used solely as the pressure cooker. The multifunctional overlap pressure cooker has the advantage of high utilization rate.

Description

Multifunction overlap pressure cooker

The utility model relates to a kind of culinary stack pressure pot.

Prior art such as Chinese patent 88207616.7 described " multi-layer combined pressure cooker ".This pressure cooker comprises that by more than one secondary pot and existing pressure cooker blast pipe, pressure limiting valve, safety valve, the sealing ring led on pot, pot cover, panhandle and the pot cover form.The characteristics of this patent are to be compounded with the secondary pot of multilayer between main pot and pot cover, secondary pot upper periphery shape is identical with main pot peripheral shape, the following peripheral shape is identical with pot cover, and secondary pot bottom has passage, in the secondary pot separate type small container or integral body or the lattice container that is used is arranged.Though the multiple food of the prior art boiling simultaneously, but because the interior pressure of its main pot and secondary pot is identical, the multiple food boiling of need different pressures or time is brought inconvenience, the province's energy efficiency that saves time is not high, ineffective when the pair pot is not with the compound use of main pot simultaneously, the utilization rate of pot is not high.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide in a kind of main pot and the secondary pot different pressures is arranged, can carry out boiling simultaneously according to required different cooking pressures of different foods or time, the multipurpose stack pressure pot that province can be effective that saves time can make main pot become pressure cooker separately with secondary pot simultaneously and use.

Solution of the present utility model is: a kind of multipurpose stack pressure pot, comprise main boiler body, pot cover, panhandle, easing valve, pressure limiting valve, between main boiler body and pot cover, set up the secondary pot more than one deck, be characterized in that each secondary the bottom of a pan end connects a connection cover, connection cover following peripheral shape is identical with the pot cover peripheral shape, secondary pot bottom is fixed with breather pipe, and the unidirectional secondary valve of pressing is arranged in the breather pipe.When the pressure in the main pot was enough big, the heat steam in the main pot entered in the secondary pot from breather pipe by backing down the secondary valve of pressing, and makes in the secondary pot to reach certain pressure.Because unidirectional secondary effect of pressing valve, having guaranteed has required enough pressure in the main pot, makes main pot different with secondary pot inner pressure.Equally, the secondary pot inner pressure of pressure ratio last layer in the secondary pot of following one deck is big, thereby makes each lamination pot inner pressure by successively decreasing from last formation down.

The utility model can add air bleeding valve on connection cover or pot body.Its effect is after the food of boiling in certain layer of pot reaches the scheduled time, can open the air bleeding valve of this pot, discharges the steam of this layer, is unlikely to food heating of a specified duration excessively in this layer pot.Because the unidirectional secondary valve of pressing has stoped the downward one deck of steam to flow, so after certain layer of air bleeding valve discharged steam, the lamination above it was unaffected, continues in boiling.

Breather pipe height of the present utility model is higher than secondary pot pot height degree, exempts to make air inlet pipe blocked when boiling soup juice food.

The utility model has the advantages that: owing to be provided with the unidirectional secondary valve of pressing in breather pipe, when having only the pressure of one deck instantly enough, steam just can enter last layer, thereby makes each stressor layer form gradient.The unidirectional secondary opening of valves threshold values of pressing of each layer suitably is set, and can satisfy needs different pressures or the food boiling of time, thereby saves time and the energy.Simultaneously, be connected with connection cover between the secondary pot of the utility model and main pot, secondary pot and the secondary pot, remove connection cover after, each pot adds that having pot cover now can become the pressure cooker use respectively separately, has improved the utilization rate of this pot.

The utility model can further specify in conjunction with the accompanying drawings.

Fig. 1 is the utility model embodiment 1 structural representation Figure of abstract of holding concurrently;

Fig. 2 is the utility model embodiment 2 structural representations;

Fig. 3 is the connection cover structure chart;

Fig. 4 is the side view of Fig. 3.

The utility model embodiment 1 is as Fig. 1, Fig. 3 and shown in Figure 4: multipurpose stack pressure pot is by main boiler body 1, pot cover 2, panhandle 3, the secondary pot 6 that is connected by connection cover 7 between main boiler body 1 and the pot cover 2, the breather pipe 8 that secondary pot 6 bottoms are provided with, be placed on secondary pot 6 bottom blow vents in the breather pipe 8 and greater than the spheroid 9 of ventilation bore, easing valve 4 on the pot cover 2, pressure limiting valve 5 are formed, wherein secondary pot 6 bottoms also are provided with fuse sheet 11, and the height of breather pipe 8 is higher than the height of 6 pots of bodies of secondary pot.When main boiler body 1 internal pressure is enough, steam will back down spheroid 9 and enter secondary pot 6 from breather pipe 8, thereby to the food boiling in the secondary pot, when secondary pot 6 inner vapors are enough big, steam will be discharged from easing valve 4 parts.Suitably determine the weight of spheroid 9, can make the pressure in main boiler body 1 and the secondary pot form required difference, be convenient to the different foods of boiling.

The utility model embodiment 2 is as Fig. 2, Fig. 3, shown in Figure 4, and the pair of stack pressure pot presses valve 9 to adopt a pressure valve, and pressure valve is on breather pipe 8 tops, and connection cover 7 is provided with an air bleeding valve 10, and other structure is identical with embodiment 1.Because connection cover 7 is provided with air bleeding valve 10, after the food of boiling in the main boiler body 1 is good, gas in the main boiler body 1 can be discharged from air bleeding valve 10, after gas in the main boiler body 1 is discharged, pressure in the secondary pot 6 is greater than the pressure in the main boiler body 1, the steam that the pressure valve 9 at this moment secondary pot top limits in the secondary pot 6 enters in the main boiler body 1, continues the pressure cooking in the secondary pot 6 of maintenance.
