the high flow steam carpet handle has two main structures , the handle 11 and recovery tank 12 , shown in fig1 and 2 . the handle 11 is made of 1 inch o . d . 18 gauge steel . attached to the handle are two essential assemblies . the control panel assembly 14 ( fig3 ) is made of 1 / 8 &# 34 ; vacuum formed plastic . this control panel assembly 14 contains two switches 16 and 18 . the vacuum switch 16 ( fig3 ) is used to turn the vacuum motor 24 ( fig4 ) on and off . the other switch on the control panel assembly 14 ( fig3 ) is the spray jet switch 18 ( fig3 ). this switch is used to either open or close the solenoid valve 28 ( fig4 ). the other essential assembly connected to the handle is the axle assembly 20 ( fig3 ). this assembly 20 attaches to the bottom of the handle as shown in fig3 . the wheels 22 ( fig3 ) go on the axle assembly 20 ( fig3 ) at opposite distal ends of the axle 20 . when both the control panel assembly 20 and the axle assembly are attached to the handle , it is called the handle assembly 45 ( fig3 ). the second main structure on the machine 10 is the recovery tank 12 . ( fig2 ). this recovery tank 12 is made of 3 pieces of 0 . 063 thickness 5052 h - 32 aluminum . the main body of the recovery tank 12 is formed out of the flat 76 ( fig1 ). the flat 76 is then molded to form the main body of the recovery tank 80 as is shown in fig1 . the remaining two pieces of the recovery tank 12 are the end caps 78 shown in fig9 . these two pieces are identical and are welded to either side of the main body of the recovery tank 12 . as can be seen in fig1 , seven of the eight bends , 13 , 15 , 17 , 19 , 23 and 25 , in the main body of the recovery tank 12 are 45 degrees bends . this is done to strengthen the inside of the recovery tank 12 . this construction reduces the flexing of the tank when subjected to strong vacuum , maintaining its yield strength . once the recovery tank 12 is formed and welded , five structures are mounted together to form the machine 10 . the recovery tank 12 contains the vacuum motor 24 ( fig4 ) designated with a circled v , the discharge pump 26 ( fig4 ) designated with a circled p , and the solenoid valve 28 ( fig4 ) designated with a circled s . connected therewith are the engine compartment housing 30 ( fig5 ), and the handle assembly 45 ( fig3 ) which is shown connected to the recovery tank in fig5 . the vacuum motor 24 ( fig4 ) mounts over a hole in the back and in fig6 of the recovery tank 12 . this hole is called the vacuum hole 72 and is shown in phantom in fig2 . this hole , as indicated , is on the back wall of the recovery tank 12 . this allows vacuum to enter the recovery tank 12 . the discharge pump 26 ( fig4 ) mounts over a hole 73 in the back of the recovery tank 12 . the discharge pump 26 is attached to the recovery tank 12 discharge hose 34 ( fig6 ) which connects the pump 26 to the water filter 32 ( fig6 ) which is also located in the recovery tank 12 . the solenoid valve 28 ( fig4 ) also mounts to the back of the recovery tank 12 . this valve controls water flow to the spray jet 44 shown in fig7 and 8 . the engine compartment housing 30 ( fig5 ) also mounts on the back of the recovery tank 12 . this housing 20 is made out of 1 / 8 inch thick vacuum formed plastic . its main function is to cover and protect the vacuum 24 , pump 26 and valve 28 , and such from dust , lint , water , etc . the handle assembly 45 ( fig3 ) also attaches on the back of the recovery tank 12 as shown in fig5 . on the inside of the recovery tank 12 are three essential parts . the float switch 36 ( fig6 ) designated with a circled f . the water filter 32 ( fig6 ) designated with a circled wf , and the baffle 38 ( fig6 ). the float switch 36 ( fig6 ) regulates the amount of extracted water contained in the recovery tank 12 . when the water level reaches three inches on the inside of the recovery tank 12 , the float switch activates the discharge pump 26 ( fig4 ). the discharge pump starts pumping the water out of the recovery tank 12 until the water level , on the inside of the recovery tank 12 , goes down to 1 / 2 inch . when the water level is 1 / 2 inch on tank 12 , the float switch 36 ( fig6 ) deactivates the discharge pump . the water filter 32 ( fig6 ) filters the extracted water , in the recovery tank 12 , from hair , lint , sand , etc . this is used to protect the discharge pump 26 ( fig4 ). it is made from 26 gauge perforated stainless steel , with 0 . 032 diameter holes . the baffle 38 ( fig6 ) mounts over the vacuum hole 72 ( fig2 ) on the inside of the recovery tank 12 . it is made from 1 / 8 inch thick vacuum formed plastic . the opening on the baffle 38 that allows vacuum to enter the recovery tank 12 is located as high up on the baffle as possible . this opening is used to channel the vacuum generated by the vacuum motor 24 ( fig4 ) to the top of the recovery tank 12 . this creates the height differential between the vacuums entrance point and the highest extracted water level . this prevents the vacuum motor from drawing in the extracted water on the bottom of the recovery tank 12 . an optional air filter ( not shown ) goes over the opening on the top of the baffle . this filter can be made out of foam , perforated metal , etc . it is mainly used when the machine is being used for dry vacuuming . in dry vacuuming , the hair and lint being drawn into the recovery tank 12 can damage the motors . this air filter prevents it from being drawn into the vacuum motor . the spray jet assembly 43 ( fig7 ) contains the spray jet support 42 ( fig7 ), the spray jet 44 ( fig7 ), and the spray jet supply hose 46 ( fig7 ). this assembly mounts 43 on the bottom of the recovery tank 12 as shown in fig8 . the spray jet support 42 ( fig8 ) is used to secure the spray jet 44 ( fig7 ) in a fixed position . the spray jet supply hose 46 ( fig7 ) attaches to the front of the solenoid valve 28 ( fig4 ) and provides water flow , when the solenoid valve 28 ( fig4 ) is open . on the front face of the recovery tank 12 is a large opening 48 . this opening is called the window channel opening 48 ( fig2 ). this window channel opening 48 ( fig2 ) is where the window channel assembly 50 ( fig1 ) fits . the window channel assembly is made of three main parts . the window 82 , the channel 84 , and the window gasket 86 . the window 82 is made out of clear plastic and provides a visual effect when extracting . the operator is able to see what is being removed out of the carpet . the channel 84 is made out of vacuum formed plastic and attaches to the window 82 ( fig1 ). the channel 84 directs the extracted water entering the recovery tank 12 towards the bottom of the recovery tank 12 . without this channel the extracted water would easily be drawn through the baffle 38 ( fig6 ) and into the vacuum motor 24 ( fig4 ). the window gasket 86 goes around the outside of the window 82 . when the vacuum motor 24 ( fig4 ) is turned on , the vacuum generated by it pulls the window channel assembly 50 ( fig1 ) against the front face of the recovery tank 12 . this window gasket 86 ( fig1 ) seals the window channel assembly 50 ( fig1 ) against the front face of the recovery tank 12 during operation . attached to the very front of the recovery tank 12 are an inner lip 52 and an outer lip 54 shown in fig1 . both the inner and outer lips are made of 18 gauge stainless steel and provide a tough long lasting surface for the water pick - up portion 56 of the machine . the inner lip 52 and outer lip 54 are attached with about an 1 / 8 inch gap between them . the 1 / 8 inch gap forms a channel to the inside of the recovery tank 12 . this 1 / 8 inch gap and the channel are called the water pick - up 56 ( fig1 ). this water pick - up allows vacuum generated by the vacuum motor 24 to contact the carpet . the vacuum draws water out of the carpet , between the lips 52 and 54 , up the channel 56 and into the recovery tank 12 . two things are required to allow the machine 10 to perform at high efficiency . a constant high volume clear water source and the ability to discharge a high volume of extracted water . these two things are achieved with two hoses . the supply hose 58 ( fig5 ) and the discharge hose 60 ( fig5 ). the supply hose 58 ( fig5 ) provides a source of clear water to the machine . on one end it connects to a clean water source from a sink or faucet 70 ( fig5 ) and on the other end connects behind the solenoid valve 28 ( fig4 ). the discharge hose 60 ( fig5 ) provides a way for the machine 10 to get rid of extracted water . it connects on one end to the back of the discharge pump and on the other end into a toilet 62 or other drain ( fig5 ). another item the machine 10 needs to operate is an electric source . since the machine 10 runs on a regular ac current , this is easily achieved with a power cord 64 ( fig5 ). the power cord on one end runs to the electrical parts ( motors , etc . ), and on the other end to a wall socket 66 ( fig5 ). to make the machine practical it needs both a constant high volume water source , and the ability to discharge the dirty extracted water . this is achieved as follows . by using a faucet adapter 68 ( fig5 ), the machine 10 supply hose 58 ( fig5 ) is connected directly to the faucet 70 ( fig5 ). this gives the machine 10 access to a high flow pressurized water system . once connected to the water system the hot water is turned on . the normally closed solenoid valve 28 ( fig4 ) blocks any water flow until you are ready to clean . next , insert the end of the discharge hose 60 ( fig5 ) into the toilet 62 ( fig5 ) or other sanitary disposal . next , plug the power cord 64 ( fig5 ) into a wall socket 66 ( fig5 ). with the operator &# 39 ; s hands on the top of the handle , the operator &# 39 ; s fingers have easy access to the vacuum switch 16 ( fig3 ) and the spray jet switch 18 ( fig3 ) located on the control panel assembly 14 ( fig3 ) turn the vacuum switch 16 ( fig3 ) on which turns the vacuum motor 24 ( fig4 ) on and which supplies immediate vacuum or suction to the water pick - up 56 ( fig1 ). to clean , turn the spray jet switch 18 ( fig3 ) on . this opens the solenoid valve 28 allowing water from the faucet to pass through it to the spray jet 44 which sprays the water on the carpet . pull the machine backwards to extract the water . as the machine is pulled backwards , the water pick - up 56 ( fig1 ) vacuums the water back out of the carpet . to stop this cleaning process , turn the spray jet switch off . this closes the solenoid valve and water flow to the spray jet 44 stops . as the machine 10 is operated , pulling the machine backwards with spray jet switch on , the water pick - up 56 ( fig1 ) draws the dirty extracted water into the recovery tank 12 . once inside the recovery tank 12 the dirty water is directed by the channel 84 ( fig1 ) to the bottom of the recovery tank 12 . when the level of dirty water on the bottom of the recovery tank 12 reaches 3 inches , the float switch 36 ( fig6 ) activates the discharge pump 26 ( fig4 ). the discharge pump pulls the dirty water in the recovery tank 12 through the water filter 32 ( fig6 ) up the recovery tank 12 discharge hose 34 ( fig6 ) through the discharge pump into the toilet 62 ( fig5 ) or other sanitary disposal . when the discharge pump has removed all but about 1 / 2 inch of extracted water from the bottom of the recovery tank 12 , it is deactivated by the float switch 36 . when the extracted water level reaches 3 inches , the float switch 36 will reactivate the discharge pump 26 . even though the present machine 10 uses a much higher water flow , more than 3 times as much , than other known machines , it leaves carpets much dryer . since water is the only carrier of dirt and soils in the steam carpet cleaning process , the machine 10 has greatly increased the cleaning process of steam carpet cleaning by increasing the flow rate of said water . the foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom for modifications will become obvious to those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention or the scope of the appended claims .
