Definitions

  • the present invention refers to a laundry dryer machine.
  • Laundry dryer machines are known which are provided with devices for the detection of the level of the condensation water.
  • most part of said machines are provided with tanks for the collection of the condensation water due to the flow of humid warm air coming out of the basket where the laundry to be dried is contained.
  • the humid air when condensing is collected in tanks usually located under the condenser; said tanks can be fixed or of the removable type.
  • the devices normally used for the detection of said pre-established level in the condensation water tank are pressure switches.
  • an object of the present invention is to provide a laundry dryer machine with a new device for the detection of the level of the water in the tank containing the condensation water.
  • this object is obtained by means of a laundry dryer machine comprising a basket for the containment of the laundry to be dried, means for the conveying of heated air inside said basket, heat exchanger means passed through be the air coming from the basket, at least one tank for the collection of the condensation water produced by said heat exchanger means, characterised in that it comprises optical means for the detection of the reaching of a pre-established level of water inside said tank.
  • a laundry dryer machine according to a first embodiment of the present invention is shown.
  • Said machine is provided with a cabinet 1 having an opening 2 for the loading of the laundry on the front wall 3 of the cabinet 1.
  • the laundry dryer machine comprises a door 4 suitable to close the opening 2 of the cabinet 1 and a basket 5 suitable to contain the laundry that must be dried; the door is hinged to the front wall 3 of the cabinet 1.
  • the basket 5 can be fixed or it can be made rotate by an electric motor and opportune kinematical means.
  • the basket 5 comprises an opening lined up with the opening 2 of the cabinet 1 for the loading of the laundry to be dried.
  • the laundry dryer machine comprises a heat exchanger device 6 through which the humid air coming from the basket 5 passes.
  • the humid air that passes through the device 6 gets cooled by means of cold air coming from a fan 32 driven by a motor 33, as better visible in Figure 5; in such way droplets of water are produced by the device 6.
  • the air coming from the device 6 is sent toward a duct 30 and there it is heated by the resistors present inside the duct 30; the heated air is directed by means of a fan 31 toward the basket 5 in order to dry the laundry.
  • the device 6 is preferably arranged under the basket 5, as visible in Figures 1 and 4.
  • a unit 10 for the collection of the condensation water coming from the same device 6 is arranged.
  • Said unit 10 comprises means 11 made up of a sheet metal shaped as a funnel suitable to collect the condensation water coming from the device 6.
  • Said sheet metal has a hole 12 for the outflow of the condensation water being collected.
  • a tank 13 is arranged having a hole 14 for the inlet of water which corresponds to the hole 12 of the sheet metal 11, as better visible in Figures 1 and 4.
  • the tank 13 rests on the bottom 8 of the laundry dryer machine inside an interpage 9 obtained within the bottom part of the machine.
  • the tank is of the removable type and it has a handle 15 for the extraction of the same from the interpage 9 from the front part of the laundry dryer machine, as better visible in Figures 1 and 6.
  • the unit 10 comprises optical means 20 for the detection of the reaching of a pre-established level P of water inside said the tank 13, as better visible in Figures 1-3.
  • Said optical means comprise a LED emitter 21 and a LED receiver 22 arranged at a certain distance from each other; the LED 21 emits an infrared ray which is received by the LED 22.
  • the optical means 20 comprise a device 200 connected with the LED 22 and suitable to detect the degree of reception of the infrared ray; in fact the lower or the higher absorption of the infrared ray depends on the interposed mean and it is therefore possible to discriminate the presence of water from the air.
  • the LED 21 and 22 are respectively arranged on two extensions 23 and 24 of the optical means 20 at a certain distance D from each other; between said extensions 23 and 24 an extension 17 of a recess 16 of the tank 13 is arranged.
  • the latter is preferably made of polypropylene, that is a material transparent to the infrared rays.
  • the optical means are preferably connected with an electronic timer (not visible in the figures) that it is suitable to stop the operation of the laundry dryer machine when the pre-established water level P inside the tank 13 is reached.
  • a laundry dryer machine according to a second embodiment of the present invention is shown; the elements equal to the first embodiment will be identified by the same numerical references.
  • the laundry dryer machine of said second embodiment differs from the laundry dryer machine of the first embodiment because it comprises two tanks 130, 131 for the collection of the condensation water coming from the heat exchanger 6 through which the air coming from the basket 5 passes.
  • the air that passes through the device 6 gets cooled by means cold air coming from a fan 32 driven by a motor 33, as better visible in Figure 9.
  • the air coming from the device 6 is sent toward a duct 30 and there it gets heated by the resistors present inside the duct 30; the heated air is directed by means of a fan 31 toward the basket 5 in order to dry the laundry.
  • the device 6 is preferably arranged under the basket 5, as visible in Figures 7-9.
  • the laundry dryer machine comprises a unit 10 for the collection of the condensation water coming from the same device 6.
  • Said unit 10 comprises means 11 made up of a sheet metal shaped as a funnel suitable to collect the condensation water coming from the device 6.
  • Said sheet metal has a hole 12 for the outflow of the condensation water being collected.
  • Under said sheet metal 11 the tank 130 is arranged which has a hole 14 for the inlet of water which corresponds to the hole 12 of the sheet metal 11, as better visible in Figures 7 and 8; the tank 130 is similar to the tank 13 of the first embodiment.
  • the tank 130 rests on the bottom 8 of the laundry dryer machine inside an interspace 9 obtained within the bottom part of the machine; the tank 130 is fastened to the interspace 9.
  • the unit 10 comprises optical means 20 for the detection of the reaching of a pre-established water level P inside said tank 130, as better visible in Figure 7.
  • optical means 20 in the laundry dryer machine of the second embodiment of the invention are arranged in proximity of the front part of said machine whereas in the machine of the first embodiment they were arranged in proximity of the back part.
  • the tank 130 is in hydraulic connection with a tank 131 arranged above the basket 5 in an interspace 51 located in proximity of the top 50 of the cabinet 1. Said hydraulic connection is made by means of a pump 41 which allows the transport of the condensation water from the tank 130 to the tank 131 through a duct 42.
  • the pump 41 is connected with the tank 130 from which it takes the condensation water that is brought through the duct 42 to the tank 131 through a an inlet hole 43.
  • the tank 131 is of the removable type and it has a handle 44 for the extraction of the same from the interspace 51 from the front part of the laundry dryer machine.
  • a laundry dryer machine according to a third embodiment of the present invention is shown; the elements equal to the first embodiment will be identified by the same numerical references.
  • the laundry dryer machine of said third embodiment differs from the laundry dryer machine of the first embodiment because it comprises two tanks 140, 141 for the collection of the condensation water coming from the heat exchanger device 6 though which the air coming from the basket 5 passes; the device 6 is preferably arranged under the basket 5, as visible in Figure 11.
  • the laundry dryer machine comprises a unit 10 for the collection of the condensation water coming from the same device 6.
  • Said unit 10 comprises means 110 made up of a sheet metal shaped as a funnel suitable to collect the condensation water coming from the device 6.
  • Said sheet metal has a hole 120 for the output of the condensation water being collected.
  • tank 140 having a hole for the inlet of water 145 is arranged to correspond to the hole 120 of the sheet metal 110, as better visible in Figure 12.
  • the tank 140 rests on the bottom 8 of the laundry dryer machine and it is fastened there.
  • the unit 10 comprises optical means 20 for the detection of the reaching of the pre-established level of water P inside said tank 140.
