2. Structure and performance characters
 

· There are effective insulation material sticking on both sides of the chamber as well as on top of it to keep heat from escaping rapidly and to decrease noise.

· There are two types as single door compared with double door.
· The door can be opened out and downwards to a horizontal level as a flat roof for placing loading trolleys and frame on.
· An electronic locking device is equipped on the door, which can prevent the door from being opened during the operation of a 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.
· A nice viewing window is equipped on the door, through which the inner operation condition can be observed.
· The illuminating lamp in the cabin can be some help for clearer view of the operation condition inside.
 

· 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.
· The 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 90℃.
· The water is drained out automatically after each cleaning in order to prevent the objects from recontamination.
· The highly efficient drying system available can dry the cleaned objects in the cabin rapidly, promoting the efficiency of utility of these appliance. 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. The decorating covers are made of thread stainless steel imported from abroad.
 

· CPU224 (PLC) of S7-220 from SIMENS, Germany is adopted as the major controller, which is tiny in size, with mightiness of function and convenience for maintenance. Thermal-resistance module of high precision ( of 0.1℃) 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. In addition, remote diagnostic function can be supplied on the machine according to the specific requirement of customers.
· Data collector: A floater switch made of 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.
· The executive section: AC contactor and heat protector from SNAD, France are equipped on the machine to control power supply to the electrical heating tube for water, and that for air and to the 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.
 

There are two loading trolleys for the standardized configuration of each equipment, one is for apparatus and the other is for canula, which are all made of advanced stainless steel. The trolley for apparatus with a large capacity is widely used for loading surgical instruments such as scissors, nippers and etc, and also for loading basins, trays and bowls in surgery. The trolley for loading canula is for the purpose of treatment to narcosis canula and other kinds of pipes.
 

3. Program and the working flow:
·P1-P6 represent the 6 preset programs, whose working flow is as the following:
a. Cleaning processes: Enzyme lotion is supplied automatically.
b. The first cleaning;
c. The second cleaning;
d. The third cleaning: Lubrication for apparatus is supplied automatically (no need for narcosis canula).
eThe drying stage.
