Definitions

  • the invention relates to a laundry treatment machine, in particular tumble dryer with a drum rotatably mounted in a housing, a closable with a door feed opening and a fan and a heater for generating a process air stream, which flows in the locked state of the door through the drum and wherein the heater from a heat exchanger exists, which is connected via connections to the hot water network of a stationary heat generator.
  • a household clothes dryer known, with a driven by a motor drum laundry, and arranged outside the laundry drum means for heating the dry air flow, which is conveyed by the laundry drum by means of a blower.
  • the tumble dryer is provided with a connection for the domestic hot water network.
  • the device for heating the dry air consists of a heat exchanger connected to the hot water network.
  • the invention thus has the object to further develop a laundry treatment machine and here in particular a tumble dryer, which is connected to an external heat source, that the efficiency of heat utilization is better utilized.
  • the heat transferable at small temperature gradients between the flow temperature and the ambient temperature is much more efficient, in which a single-stage heat transfer is used with large heat transfer surfaces used. This can be achieved with the use of heating heat acceptable drying times.
  • the heat is transferred directly in one stage from the heating water to the laundry.
  • the direct contact of the laundry is used with the large heat transfer surface of the drum shell.
  • the second drying section provides a suitable air supply in the drum on the large heat transfer surface of the drum shell for drying the laundry in the drum.
  • the drum itself is designed as a heat exchanger, wherein the hot water supply takes place directly above or in the drum wall.
  • the hot water supply is carried out here via arranged in the drum ribs.
  • the supply of hot water takes place via a drum pin formed as a tubular pin, which is connected to a rib arranged in the drum housing, which forms the flow.
  • the return of the hot water is in this case carried out via a tubular sleeve lying around the pipe sleeve, which is connected to a further arranged in the drum rib and which forms the return.
  • the flow forming ribs and the return ribs are connected via a provided in the drum opening edge pipe.
  • a fan is arranged behind the drum, which in particular generates the necessary air flow which flows through the drum.
  • the tumble dryer according to the invention can be designed as a vented dryer or else as a condenser dryer.
  • FIGS. 1 and 2 Show in particular laundry treatment machines and here tumble dryer 1, with a rotatably mounted in a housing 2 and a drum 3 with a door 4a closable feed opening 4, wherein in the housing 2, a fan 5 and a heater 6 is provided for generating a process air stream 7, the in particular in the locked state of the door 4a flows through the drum 3.
  • the heater 6 shown with the arrows is connected via terminals 8 to the hot water network of a stationary heat generator, not shown.
  • the drum 3 itself is designed as a heat exchanger, wherein the hot water supply takes place directly or in the drum wall 9. From the cut representation of the FIGS. 1 and 2 It is also clear that the water flow takes place via ribs 10.1 and 10.2 arranged in the drum.
  • the hot water is supplied via a drum pin formed as a pipe pin 11, which is connected to a rib 10. 1 arranged in the drum 3, which forms the feed line V.
  • the return of the hot water takes place via a tubular sleeve 12 lying around the pipe sleeve 12, which is connected to a further arranged in the drum 3 rib 10.2, which forms the return R.
  • FIG. 1 which constitutes a condenser dryer
  • the condenser 15 is arranged below the drum 3.
  • the resulting condensate is collected.
  • 12 leaking leakage water can be removed by means of a line 16 from the terminals 8 and from the connecting piece between the terminals 8 and the pipe pin 11 / tube sleeve.
  • FIG. 2 here represents a ⁇ klufttrockner, in which case the fan 3 sucks fresh air from the outside and this leads through the drum 3, according to the direction of the arrow and via an exhaust pipe 17 to the environment again releases.
  • the aforementioned type of heat input into the drum is particularly well suited for heat pump dryer, because in this case usually the air is not heated as much.
