Description
Technical field
The utility model relates to the special-purpose lavatory of a kind of manned spacecraft.
Background technology
China has realized the emission and the operation of manned spacecraft at present, and is about to be implemented in the space station that space is set up long-term Attended mode.Along with the prolongation of astronaut in the space residence time, need a large amount of personal hygiene problem of corresponding solution, first-class such as washing one's face, wash hair, brush teeth, have a bath, rub one's body with a towel, change underwear and foot bath and cutting finger (toe).If the astronaut only stops several days time at space, can solve the oral hygiene problem with chewing chewing gum with sterilizing function, wait and have a bath again after returning ground; When the astronaut stops several weeks, several months at space, even the longer time time, just must in spacecraft, solve personal hygiene problem such as have a bath.Astronaut's dirts such as the globule that produced, scurf of washing one's face and rinsing one's mouth can be suspended under the weightlessness of space condition in the spacecraft, as let alone floating diffusion in spacecraft, can cause that electrical equipment damages in the spacecraft, also may enter astronaut's face, harm astronaut health.So, in the long-term spacecraft on duty of astronaut, must set up specialized facilities for activities such as the astronaut wash one's face and rinse one's mouth, protect the interior environment of spacecraft not contaminated simultaneously.
The utility model content
Technical problem to be solved in the utility model provides a kind of being installed in the manned spacecraft, for the astronaut special-purpose lavatory that safe ready uses in space.
The utility model is the special-purpose lavatory of a kind of manned spacecraft, and it is to surround the confined space unit that forms by sidewall, roof and diapire.Spatial form and the size reserved for this purpose in lavatory profile and the manned spacecraft adapt.
The sidewall of one side sets out inlet in the lavatory, the gangway is provided with the two seals door, the first road hermatic door is towards the spacecraft accommodation, the second road hermatic door is indoor towards the lavatory, be provided with between the two seals door and be similar to the same collapsible stretching structure of accordion bellows, and the two seals door is connected.When this stretching structure was in stretched condition, the space in it constituted the passage room of lavatory.Establish supply ventilating fan, illuminating lamp at the lavatory roof; In the lavatory, establish wash stand, on the diapire of wash stand middle section, the dirt holding groove is set, Advance plate is set in groove; Establish exhaust fan and blow-off line at dirt holding groove sidewall; Establish sitting posture retainer and foot bath pallet in the dirt holding groove outside; Water supply atomising installation with little shower nozzle is set on table top, under table top, the cabinet is set, deposit various foreign material fully; Establish a bath bag storage rack in another routine table top sky.
As optimization, at lavatory sidewall and wash stand table top nylon cingulum or hasp are set, the various items that is used for fixing astronaut's health and in the lavatory, uses; Bottom surface at the dirt holding groove is provided with nylon fastener belt, is used for fixing Advance plate.
As optimization, the source switch of electrical equipments such as lavatory intraoral illumination lamp, supply ventilating fan, exhaust fan is arranged at place, gangway, lavatory, and forms the difference linkage structure with the lavatory first road hermatic door.That is, the sealing family status is once opened and is driven electrical equipment electric power starting in the lavatory, and the sealing family status is once closed and opened does not for the second time influence electrical equipment power supply in the lavatory, and sealing family status secondary then drives electrical equipment power-off in the lavatory when closing.
As optimization, the air outlet of supply ventilating fan and the ventilation inlet of exhaust fan are all installed check valve, make the air can not reverse flow; Check valve or movable louver are set, in order to separation of air and bigger solid pollutant between exhaust fan and filtering net.
As optimization, the power during the exhaust fan normal operation is greater than supply ventilating fan power, makes air pressure in the lavatory a little less than the spacecraft module internal gas pressure, guarantees that the globule, the chip in the lavatory is unlikely to the lavatory of overflowing.
As optimization, lay carpet at the lavatory diapire with the cloudy button of nylon, this nylon the moon is detained and is complementary positive button of the nylon of the slippers sole of lavatory dress for the astronaut.
Because the utility model adopts passage room isolation method and the measure of vacuum suction contaminant collecting mode duplicate protection simultaneously, make astronaut's produced pollution thing of washing one's face and rinsing one's mouth obtain timely collection and treatment, thereby guaranteed spacecraft and astronaut's safety.
