Definitions

  • the present invention relates to a washing apparatus and the method thereof for the tableware including forks, knives, spoons, etc. as well as dishes, cups and glasses.
  • the washing apparatus for tableware heretofore in use has a box type frame body on which a door is swayingly mounted on the front end opening, and within the frame body is provided a rack for permitting the tableware to stand up, and by a shower means provided on the inner wall of the frame body and a shower pipe rotatably mounted below the rack, the tableware is washed in a shower discharging over the rack.
  • the washing water from the shower is hard to spurt forth all over the tableware completely, and in a country where the tableware with a deep bottom such as a glass, etc. and the tableware formed in various shapes like the Japanese tableware are mostly used, the said washing apparatus has less washing effect, and this gives rise to the fact that the said washing apparatus has scarcely been pervasive.
  • a dishwasher consisting of a tub, a basket and a device supporting the basket for rotation in the tub, a cover for the tub, a nozzle mounted eccentrically on the cover, and a device for conducting high pressure liquid to the nozzle.
  • the nozzle has a plurality of diverging orifices for directing a number of high velocity streams of liquid into the tub, some of these streams being directed against the basket to rotate it and at least one of the streams opposing such rotation.
  • a dishwasher consisting of a dish supporter, a water impeller, a motor having a rotor, a first shaft fixed to the rotor for rotation therewith, a second shaft coaxially mounted for rotation within the first shaft, a gear arrangement fixed to the first and second shafts and coupled to each other in a manner whereby the first shaft drives the second shaft at a rotary speed substantially less than that of the first shaft and in the opposite direction thereto, a coupling device for removably fixing the dish supporter to the second shaft, and a device for fixing the water impeller to the first shaft.
  • the present invention provides a washing apparatus for tableware which is capable of removing any filth on the tableware reliably and quickly.
  • the present invention additionally provides a washing apparatus for tableware such that the tableware can be deprived of filth in a shorter time by whirlpool flow generated alternately in reciprocating motion in the washing water immersing the tableware, and that energy saving is also effective.
  • a washing device which comprises: a washing tank provided with a means for introducing water into the washing tank; a rack, rotatably mounted in the washing tank, for receiving and holding one or more article to be washed; a water-agitating means rotatably mounted in the washing tank for rotating water in the washing tank; and drive means for simultaneously rotating the agitating means and the rack in mutually opposed directions;
  • the water-introducing means has spray nozzles disposed at multi-stepped positions on the side wall in the washing tank to enable water to jet from lateral directions and has water-supply nozzles, and in that the drive means has a reversible motor.
  • the rack is mounted above the water-agitating means, which is preferably in the form of a plate, and in preferred embodiments the rack is removably mounted in the washing tank.
  • the water-agitating means is mounted in the bottom of the washing tank.
  • a washing device according to the first aspect of the present invention, which method comprises:
  • detergent is introduced into the washing tank before the drive means is actuated.
  • the article may be rinsed with hot water introduced via the means for introducing water.
  • the temperature of the hot water is preferably in the range of from 40°C to 60°C.
  • Figure 1 shows a vertical section through an embodiment of the washing device according to the present invention.
  • the washing tank is supported by legs 2- -.
  • the washing tank 1 has an opening at its upper end, on the inner wall of which are provided a plural number of shower jet outlets 1a, 1a,--, and water supply hole 1b.
  • the piping connected to the shower jet oulet and the water supply hole is provided with valves 3, 4.
  • a drain port 1c At the bottom corner of washing tank 1 is provided a drain port 1c.
  • the drain pipe is also equipped with a valve 5.
  • an agitating plate 6 for causing the water poured into the tank to be given a whirlpool flow and a tableware rack 7 for receiving and holding the tableware, and these are rotated each other in opposed directions by the drive mechanism which will be described hereunder.
  • a cylindrical shaft 9 for driving the tableware 7 is axially supported pivotally through bearings in the bearing case 8 mounted under the washing tank 1. The upper end of this cylindrical shaft extends outwardly in the washing tank 1.
  • a drive shaft 11 for agitating plate 6 is pivotally supported through bearings 12, 12, the upper end of which is made to extend outwardly in the washing tank 1.
  • the rotary shaft 14 axially supported on the bearing case 8 pivotally through bearing 13 is provided with gears 15 and 16 axially attached thereto; one gear 15 is in meshing relation with the gear 17 connected to the shaft 12 and another gear 16 is in meshing relation with the gear 18 connected to the cylindrical shaft through an intermediate gear (shown by dotted line).
  • the shaft 11 and the cylindrical shaft 9, therefore, rotate mutually in opposed directions.
  • On the upper end of cylindrical shaft 9 located at the inner bottom of washing tank 1 is firmly fixed the center portion of a rotary plate 19, and the rotary plate is provided with a lock frame 20 on its peripheral part. While supported by this frame 20, the tableware rack 7 is rotated together with the lock frame when taken hold of with a hook pin provided upwardly on part of the said frame 20.
  • the upper end of the shaft 11 passing through the rotary plate 19 is coupled to the agitating plate 6.
  • the lower end of shaft 11 is provided with a pulley 21.
  • the belt 23 is placed between this pulley and another pulley 22 fitted on the rotary shaft of a motor M installed at the lower portion of working tank 1, thereby imparting the rotary force of the said motor to the shaft 11 and cylindrical shaft 9.
  • a heater 24 On the inner bottom of washing tank is provided a heater 24.
  • agitating plate 6 and rotary plate 19 are to be rotated by a single motor M, they may be rotated respectively by separate motors. In this case, the gears 15, 17 are not required, and the motor for driving the tableware rack 7 for rotation will be connected to the rotary shaft 14.
  • the tableware rack 7 takes out the tableware rack 7 from the washing tank 1, then receive and hold the tableware in the rack, for example, keeping dishes, soup dishes, etc. stood up with their surfaces facing outwardly as practicable as possible and allowing glasses, cups, etc. to turn their openings outwardly.
  • the rack 7 should be so designed as to provide appropriately partitioned chambers that can afford to pile up the tableware in two layers, depending upon the shape and size of the tableware.
  • valve 3 let water (or hot water) spurt forth from the shower jet outlet 3 toward the tableware rack.
  • This is the preliminary washing for the tableware by which remnants of food stuck to the surfaces of the tableware can roughly be removed.
  • the valve 5 is then kept open in advance for drainage.
  • the shower jetting time may be approximately for 1-2 minutes. Turning the tableware rack at this time for preliminary washing enhances the washing efficiency for main washing which will be described later.
  • the shower washing using hot water at this stage is very effective for removal of oil and fat, protein, starch and the like that have adhered to the tableware.
  • the temperature of this hot water should preferably be within the range of 40-60°C for the most efficient removal of those substances, because the beef fat is liquidized at nearly 50°C but hard to be liquidized at a temperature below 40°C and, at a temperature higher than 60°C, the protein tends to be coagulated.
  • valve 3 After closing of valve 3,- - - and valve 5, the method proceeds to the immersing process by which to cause the tableware to be immersed thoroughly in the washing tank 1.
  • agitating plate 6 and tableware rack are then rotated mutually in opposed directions by the drive means consisting of the said motor, shaft 9 and rotary circular plate 19.
  • the whirlpool flow to be generated among the washing liquid in washing tank 1 by the agitating plate is restrained by rotation of the tableware rack 7, thereby causing water to undergo a disturbed, complicate flow motion.
  • water is then forced uniformly to strike filth on the surfaces of the tableware received and held in the tableware rack 7, thus filth is removed.
  • the number of revolutions of the agitation plate 6 is approximately 500 r.p.m. and the same of the tableware rack is approx. 40 r.p.m.
  • main washing valve 5 After completion of main washing valve 5 is opened to drain off the washing water. And, by opening valve 3, let water jet over the tableware to remove detergent and adhered substance from the tableware. In this case, it is also better to turn the tableware rack. Lastly, wash by hot water shower and makes dry.
  • the heater 24 may be energized for drying and sterilization as well.
