Definitions

  • the invention relates to a device for generating steam via a line and a nozzle in the container for receiving laundry to be treated a laundry treatment machine is conductive, comprising a tank, a radiator, an inlet opening for introducing water into the tank and an outlet opening for Steam or water.
  • the invention further relates to a laundry treatment machine having a device for generating steam, which can be conducted via a line and a nozzle into the container for receiving laundry to be treated of a laundry treatment machine.
  • the washing machine has a tub for holding washing liquid and the laundry to be treated.
  • the device for generating steam also referred to as a steam generator, has a tank for receiving the liquid to be evaporated and a radiator for heating the liquid to be evaporated.
  • the washing machine has a device for spraying or introducing water into the tub, wherein the device has a nozzle in the edge region of the door opening.
  • a separate nozzle for the water inlet and a further nozzle or a pipe socket for the steam is provided, wherein the supply lines are passed through the gasket.
  • US 2004/0187529 A1 is a washing machine with a tub for holding washing liquid and the laundry to be treated known.
  • the washing machine disclosed herein includes a steam generator for treating the laundry with steam.
  • a tank for the liquid to be evaporated is provided, in which the liquid is heated with a radiator.
  • the steam is fed into the treatment room or into the interior of the drum.
  • water can also be conducted via the same line and nozzle into the interior of the drum.
  • the inflow is directly connected to the water supply and is controlled by a valve.
  • the Steam generating device comprises a tank with a radiator, in which the water to be evaporated is introduced via the valve.
  • the steam outlet is provided via a pipe which projects vertically from the bottom into the tank and ends there. Surrounding walls are provided around the pipe at the top and bottom of the tank to prevent the inflowing water from flowing out of the tank via the pipe end.
  • the arrangement is intended to allow water to be continuously introduced into the tank during steam generation via the inlet valve. Since the radiator is in the region of the outlet opening or of the pipe, it can seethe during the generation of steam, with drops or, occasionally, a rush of water into the opening of the pipe for the outgoing steam. However, this is undesirable for the laundry treatment, since the laundry to be treated with steam in places becomes too wet again.
  • a steam generating device for a laundry treating machine which has an opening for the steam outlet in the upper region of the reservoir.
  • water droplets can pass through the outlet opening to the treatment chamber of the laundry treatment machine when the water in the container seeps and sprays during steam generation.
  • a steam generating device for an oven or cooking chamber is known.
  • an intermediate wall is revealed, which does not stick to the ground.
  • another container is connected to the reservoir, which is separated by a projecting from the top of the tank wall, wherein in the lower part there is a connection.
  • the arrangement disclosed herein is not suitable for use in a laundry treating machine, because the steam produced only needs to reach the cooking chamber of the oven, so that it can be used there by further heating for the cooking operations. In a laundry treating machine, the generated steam must strike the laundry directly to achieve the appropriate treatment effect.
  • At least one essentially perpendicular bulkhead is arranged on the bottom side between the outlet opening and the interior of the tank is, whose upper edge comprises or forms at least one opening which provides the passage between the interior of the tank and the outlet opening.
  • the bulkhead wall is dimensioned in terms of their height, based on the intended location of the steam generating device, so that the upper edge of the bulkhead overruns the vorratbaren in the tank water level.
  • Boiling water which is produced by cooking during steam generation, is retained by the bulkhead wall or by the projecting part of the bulkhead, so that at least virtually no droplets or splashes can get into the outlet opening behind.
  • an opening is provided at the upper edge of the bulkhead, through which the steam exits during steam generation.
  • the bulkhead movably. In a first position, it rests on the bottom of the tank so that the upper edge surmounts the water level. In a second position, it forms a distance to the ground or at least provides a passage between the interior of the tank and the outlet opening. In this case, the water, which is introduced into the tank via the inlet opening, flows out of the outlet opening to the nozzle until the level has reached the firmly formed retaining edge on the underside of the tank. This determines the water level to be stored in the tank. Before the water is heated with the help of the radiator and made to evaporate, the bulkhead must be moved to the first position, so that no water surge can reach the discharge opening via the storage edge.
  • the device for generating steam has an electrically controllable actuator with which the bulkhead is movable or with which the movement of the bulkhead can be driven.
  • actuator a servo motor with spindle drive or a magnetically driven lifting cylinder can be used, which is connected via levers or cables with the bulkhead in operative connection.
  • the bulkhead is pivotally mounted. This provides a reliable and easy mobility of the bulkhead.
  • At least one baffle which at the top of the tank and at a distance which is about 1/3 to 1/2 of the longitudinal extent of the tank between the bulkhead and the opposite end of the tank to the Bulkhead is attached. This will prevent larger in the tank Waves or splashes of water arise, which can overcome the bulkhead and get to the outlet opening.
  • the baffles act as a breakwater.
  • the baffle is dimensioned so that it ends with its lower edge at or above the surface of the water in the tank.
  • a suction acting channel disposed between the interior of the tank and the outlet opening as a suction acting channel, which forms the opening and the passage for the steam to the outlet opening.
  • the projecting into the tank channel opening is placed deeper than the upper vertex of the channel, which forms the upper edge of the bulkhead or runs over the upper edge of the bulkhead. Due to the channel opening protruding in the channel, the water level to be stored in the tank is determined.
  • the siphon is arranged obliquely on the side facing the tank, wherein the angle is about 30 to 60 degrees to the horizontal.
  • the inlet opening in the tank is arranged on the side remote from the bulkhead wall or outlet opening. This ensures that the tank is traversed during the Wasserein Anlagenung along its entire length. Deposits or other residues are flushed out and it is ensured that always the entire water supply in the tank is renewed. This is particularly important if no steam is generated for a long time and the tank would not be completely emptied during this time. This could lead to germination or unpleasant odors from the tank or from the nozzle.
  • the radiator is arranged on the outside on the underside of the tank.
  • the area to be heated can be made very flat, which deposits on the radiator can be avoided.
  • the stored water can be completely evaporated, which is not ensured in an internal, tubular heater.
  • the tank is provided with externally molded fastening means for the steam generating device, so that the attachment within the housing of the laundry treating machine is simplified.
