Motorized Door Automatic Washer Disinfector

1. Description
Newly developed, novelty structure, reliable performance and imported main parts, used for hospital disinfecting.

2. Structure & characters
A. Chamber
· Stainless steel with glass surfaces.
· Spot welding.
· Two jet arms in the chamber: Top and the bottom chamber, from which water is ejected to clean objects.
· Insulation material on both sides & top chamber

B. Airproof door:
· Two types: Single or double door.
· It can be opened downwards to a horizontal level as a flat roof for placing loading trolleys and frame on.
· Electronic locking device to prevent door open during the program. With the double door model, if necessary, the unclean area and the cleaned area can be separated from each other.
· The two doors on double-door model can be interlocked each other, the back door is closed while the front door is opened, or vice versa. So that the unclean area is separated from the clean area.
· Viewing window & illuminating lamp for operator to observe.

C. Pipeline system:
· Automatic water entry into the cabin can be realized with the equipped electro-magnetic valves imported from abroad.
· With the squirm valve lotion enters the cabin automatically and the quantity can be controlled by the preset figure in the program.
· Circulation pump of a large runoff can make the jet arms eject water turning round to clean objects effectively, and the insides of tubes and bottles can also be cleaned.
· The electrical heating tube can be controlled automatically during various stages according to the settings in the program to heat the circulation water in the cabin to a required degree of temperature.
· The primary sterilization can be carried out when water in the cabin is heated to and kept at a temperature of 90º C.
· The water is drained out automatically after each cleaning in order to prevent the objects from recontamination.
· Drying system can dry the cleaned objects rapidly. In the meantime, the hot air to be exhausted, through the heat exchanger, transmit its heat to the cold air entering the cabin resulting in a thrifty of energy and prohibiting the humid-hot air exhausted from influencing the operational area.

D. Thread stainless steel decorating covers are imported from abroad.

E. Control system:
· CPU224 (PLC) of S7-220 from SIMENS is the major controller, very tiny, with mightiness function and convenient maintenance. Thermal-resistance module of high precision (of 0.1º C) from SIMENS is applied to convert the signal sent by the thermal resistance from analogue to digital. And TD200 displayer from SIMENS is equipped as the interface between the operator and the machine. Remote diagnostic function is optional.
· Data collector: A floater switch from German produced PVDF is used to scale the liquid level in the cabin; A Japan-made tiny pressure switch with digital display is used to measure the entering liquid level and the pressure at the inlet for dry air.
· Executive section: AC contactor and heat protector from SNAD, France control power supply to electrical heating tube for water, and that for air and circulation water pump, and also to facilitate the electronic lock for controlling the opening and closure of the door. Advanced squirm pump from Germany is to control the certain amount of lotion into the cabin.

F. Two loading trolleys
They are standardized configuration, one is for apparatus and the other is for canula. They are all made of stainless steel. The trolley for apparatus with a large capacity is for loading surgical instruments such as scissors, nippers, etc. And also for loading basins, trays and bowls in surgery. The trolley for loading canula is for narcosis canula and other kinds of pipes.
