Definitions

  • Indishwashing machines it is of the greatest importance to keep the machine completely pure.
  • a source of contamination resides in the fact that after the washing and rinsing operations are completed, the liquid is removed from the machine only incompletely, such remaining liquid which is more or less contaminated due to its contact putrefaction, thus causing the dishes in a subsequent washing operation to be infected and to have a disagreeable smell and taste. Only by observing the outfiow of the liquid from the machine can asafe control of the machine being completely emptied from liquid, be attained, and in machines of certain types such an observation is impossible.
  • the principal object of the invention is to provide a control device for the valves of the machine which insures a simple, efiicient and positive manipulation of the valves and which also efiects the complete emptying of the liquid from the machine at the end of each operation.
  • Another .object of the invention is to provide a dishwashing machine of the class described in which a flow controlvalve and a discharge valve of the washing systemare connected with each other in such manner that the flow control valve is opened when the discharge valve is opened. Consequently, emptying of the washing system will take place when the flow control valve is opened, with the result that no liquid will be left in the system, nor in the whole machine as the rinsing system discharges into the washing system.
  • FIG. 1 is a perspective phantom view of a dishwashing' machine according to a first embodiment of the inventiom.
  • Fig. 2 is a somewhat diagrammatic view of the control device shown in Fig.- 1 on an enlarged scale.
  • Fig. 1 the dish-washing machine isfe'nclosed in a casing of substantially pparallelepipe'dic shape having a downwardly swingable -;c loor I I.
  • the two spraying systems for 'washing liquid and rinsing liquid are as a whole located in the lower portion of the casing, whereas the upper portion thereof forms a spraying chamber.
  • the spraying systems comprise each a motor driven pump, a liquid tank and a spraying device (see also Fig. 2).
  • the housing [4 of an electric motor and the housings I5 and iii of the two pumps for washing and rinsing liquid arranged one on either side of the motor are formed as a unit located at the side of a receptacle which by means of a partition is divided-into two spaces or tanks, an open tank H for washing liquid and a closed'tank l8 for rinsing liquid.
  • Fresh liquid is supplied to tank l8 through conduit l8.
  • Communicating with a central inlet of each pump is one end of a rigid conduit and 2
  • a pipe 22 communicating with the spraying device for washing liquid which in the embodiment shown comprises a spray pipe 23 swingable to and fro.
  • a pipe 24 communicating with the spraying device for rinsing liquid which is shown to comprise a stationary spray pipe 25 arranged along the upper edges of the washing tank l1.
  • the washing pump is provided with an outlet pipe 26 communicating with a discharge pipe 21.
  • are each formed as a valve seat for a flap valve having a spherical valve body 28 and 29, respectively, secured to a'spindle 3
  • a double-armed lever 33 engages said disks 32 and 32' at its forkedshaped ends 33'.
  • the lever is fixed on a shaft 34 guided in a switch-board 35 arranged on the, machine casing Hi, the shaft 34 carrying at its end projecting outside said switch-board an angle piece 36.
  • a handle mounted on the switchboard has a finger 41 adapted to co-operate with said angle piece 36 in a manner to be described.
  • a valve of any known type 42 is provided in the discharge pipe 26 of the washing pump 5,65
  • Fig. 1 the machine is shown in washing position, the finger 4
  • the handle 45 assumes its neutral position in which the arms 48 and 48' are out of engagement with the disks 32 and 43.
  • handle 40 When after the washing is completed the machine is to be set into rinsing position handle 40 is turned in clockwise direction from the position shown in Fig. 1 to that illustrated in Fig. 2.
  • handle 40 When the finger 4
  • the washing pump is set out of function and the rinsing pump is set into function, causing the dishes to be rinsed by jets issuing from the spray pipe -25, which discharges into the washing tank H.
  • should, preferably, have such a curvature that in set positions of handle 40 the centre of the curves coincides with the axis of rotation of the handle. Thereby any turning of the handle beyond the set position does not cause any further turning of the shaft 34.
  • handle 40 When after the rinsing operation is completed the machine is to be emptied handle 40 is shifted to washing position (Fig. 1) causing the suction valve 28 to be opened. Then handle 45 is turned in counter-clockwise direction causing arm 48' I on shaft 46 co-operating with spindle 42' of the discharge valve 42 of the washing pump to press said spindle inwardly so that the valve 42 is opened resulting in the liquid in the washing pump 5, washing tank l1 and spray pipe 23 flowing out through the discharge pipe 21.
  • valve 28 is automatically shifted into this position by arm 48 which co-operates with disk 32 lifting valve 28 into open position, when handle 45 is turned into discharging position.
  • connections between the spraying devices and the pumps are controlled by suction valves, it is also within the scope of the invention to control said connections by valves provided in the pressure conduits of the pumps.
  • a dishwashing machine comprising a spraying system for washing liquid, a spraying system for rinsing liquid, a pump in each system, a flow control valve in each system, a discharge valve connect said flow control valves and said discharge valve, said means comprising manipulating means to actuate the valves so as to open and close the fiow control valves alternately and to open the flow control valve of the washing system when the discharge valve is opened.
  • a dishwashing machine comprising a spraying system for washing liquid, a, spraying system for rinsing liquid, a pump in each system, a flow control valve in each system, means operable to connect said fiow control valves, said means comprising a manipulating member to actuate said operating means so as to open and close the valves alternately, a discharge valve in the washing system, another manipulating member to actuate said discharge valve, and means operable to connect said last-mentioned manipulating member with the flow control valve of the washing system so asto open said fiow control valve, when the discharge valve is opened.
  • a dishwashing machine comprising a spraying system for washing liquid, a spraying system for rinsing liquid, a pump in each system, a flow control valve in eachsystem, a discharge valve in the washing system, means operable to connect said flow control valves to control the setting thereof, and means to control the setting of the discharge valve, said last-mentioned control means being operatively connected with the flow control valve of the washing system soas to open said flow control valve when being set to open the discharge valve.
  • A, dishwashing machine comprising a spraying system for washing liquid, a spraying system for rinsing liquid, a pump in each system,
