The definition graph of pressure control mode involved by bright 3rd embodiment.
In the first embodiment, the stairstepping of lift car internal pressure is as shown in fig. 7, by first pressure changing unit
The two parts (pressure change rate P1/T1) and second pressure changing unit (pressure change rate 0) are constituted.The purpose is to
One pressure change part makes pressure change, and pressure is kept certain in second pressure changing unit, thus passenger is promoted to swallow
Lower action.
The inventors of the present invention are directed to the stairstepping of lift car internal pressure, by first pressure change rate (P1/T1) and the
The pressure difference (P1, P2) of two pressure change rates (P2/T2), pressure change time (T1, T2) and a ladder is used as parameter, to upper
The relevance stated between factor and ear obstruction is proved.As a result, ear obstruction can effectively be mitigated by having found
Stairstepping.
In the third embodiment, as shown in figure 8, by the pressure change rate (P1/T1) of first pressure changing unit and second
The pressure change rate (P2/T2) of pressure change part is respectively set as 0 slow and drastically two kinds of constant pressure not becoming
Rate.In addition, the pressure change rate (P2/T2) of the slow second pressure changing unit of pressure change rate is set as pressure change
0.1~0.5 times of pressure change rate of the pressure change rate (P1/T1) of the first pressure changing unit of rate drastically, and will be each
From the pressure change time (T1, T2) be set separately in the range of 3~7 seconds.It is known effectively to be changed by the above method
The alleviation effects of kind ear obstruction.
By being arranged the pressure change rate P1/T1 drastically in two kinds of pressure change rates slowly and drastically in elevator car
The crossover location (T=T0) of compartment external pressure curve and near linear, can reduce carried out in the lift car 1 pressurization and
Required air demand and capacity when the switching of decompression, and switching can be made to become convenient.
The reason for this is that when carrying out above-mentioned switching, it is being applied with the second pressure variation as slow pressure change rate
In the case of partial pressure change rate (P2/T2), due to making the pressure of plus-minus pressure become relative to lift car external pressure
Greatly, it needs moment to be transformed to decompression state from pressurized state, so needing to configure the big equipment of pressure change speed, leads to cost
Rise.On the other hand, when carrying out above-mentioned switching, it is being applied with the first pressure changing unit as pressure change rate drastically
Pressure change rate (P1/T1) in the case of, the rate of pressure change needed for equipment can be reduced.
