Definitions

  • the invention relates to a steam generator for use in a refresher dryer, wherein the steam generator at least comprises a heater for generating steam from water, a water tank, and a water pump for pumping water from the water tank to the heater.
  • the invention relates to a laundry appliance comprising such a steam generator.
  • a steam generator and a laundry appliance of such generic type is disclosed in each of the pre-published documents WO 2006/006187 A1 , EP 0 877 200 A1 , EP 0 821 096 A1 , WO 2009/022260 A1 , and US 2008/0276381 A1 .
  • Each of these documents discloses a steam generator of the boiler type comprising a vessel to be filled with evaporable liquid up to a certain level, and a heater to heat the liquid disposed at a dedicatedly low level within the vessel and covered by the liquid.
  • U. S. Patent 3,180,037 relates to a laundry appliance embodied as a clothes dryer comprising a means for dispersing a fabric treating material into said hot air in said flow passage substantially at said surface to effect a concurrent drying and treatment of fabrics in said chamber.
  • U. S. Patent 3,242,584 relates to a laundry appliance embodied as a domestic clothes drying device providing the combination of a rotatable drum for tumbling damp fabric, means for producing superheated steam, means for passing a predetermined amount of said superheated steam interiorly of said drum for vaporizing the liquid contained in the fabric tumbled by said drum, means for circulating air through said drum for extracting steam and vaporized liquid therefrom, and means for heating the air circulating through said drum for providing a final drying cycle supplementing that produced by said superheated steam.
  • U. S. Patent 4,207,683 relates to a laundry dryer having a touch-up spray for removal of wrinkles from clothing and fabrics and permanent press clothing, in particular without removing possibly present factory set creases.
  • the dryer may include a water heating unit for spraying water of a selected temperature or steam. The steam is applied to remove undesired wrinkles or odours from the laundry being treated and thus provides refreshment to the laundry. Accordingly, this dryer may be designated to be a "refresher dryer". It should be remarked that such nomination is not reserved to an appliance which is designed merely to dry laundry besides the refreshing function; instead, it will also be applied to a washer/dryer with a refreshing function.
  • DE 34 08 136 A1 relates to a tumble dryer comprising a venturi-type mixing tube which is fed with steam via a gas feeding pipe and water via an inlet.
  • a venturi-type mixing tube water is atomized due to the effect of the steam coming out of a nozzle, whereby a mist consisting of steam and water with extremely fine droplets is created.
  • This mixture is sprayed into an inside of a drum as a mist cloud.
  • textile material can be moistened and subsequently dried.
  • EP 1 275 767 A1 relates to a laundry appliance embodied as a clothes dryer or washer/dryer that treats laundry by introducing steam into a tub after the drainage of water to reduce creases.
  • Steam treatment water is held in the tub at a temperature of at least 40 °C and at most 70 °C.
  • EP 1 655 408 A1 relates to a device to generate steam in a laundry appliance which is a washing machine, said device comprising a main body and means of heating the main body, wherein a flow channel is defined in the main body such that water flowing through the flow channel is heated and converted to steam.
  • WO 2006/006187 A1 relates to a steaming device, particularly for irons or other steam electric household appliances, comprising: a tank having a water inlet opening and a steam outlet opening; a bottom wall placed inside the tank having a first and a second portion; and heating means associated to the bottom wall.
  • the first portion and the second portion are separated by a partition wall. The first portion receives a higher thermal energy pro surface unit than the thermal energy in the second portion, so as to turn water into steam more rapidly.
  • EP1 887 123 A1 relates to a process to control a steam unit of a domestic appliance, which steam unit produces water steam, especially hot or superheated water steam, which is fed to a treatment area, especially to a drum, and which steam unit comprises at least one steam generator with a heating element and water supply means to supply water to the steam generator.
  • the process is characterized in that the temperature of the steam generator, especially the surface temperature of the steam generator and/or the temperature of the heating element of the steam generator, and/or the temperature of the water steam is measured, and in a normal operation the heating element of the steam generator and/or the water supply means are controlled in such a way that the measured temperature is kept between a given lower temperature limit and a given upper temperature limit.
  • a base plate may carry different parts of the steam unit that is firmly located in the domestic appliance.
  • the water reservoir can be arranged as additional part of the modular steam unit, e.g. by arranging it on the top of the steam generator and/or the pump.
  • US 2007/0151300 A1 discloses a modular laundry system that comprises a first laundry appliance and a second laundry appliance horizontally arranged relative to the first laundry appliance.
  • the modular laundry system further comprises a laundry care function horizontal module vertically arranged with the first and second laundry appliances and having an associated laundry care function and a width that at least partially spans at least the first and second laundry appliances.
  • the object is achieved by steam generator for use in a refresher dryer, wherein the steam generator at least comprises a heater for generating steam from water, a water tank, and a water pump for pumping water from the water tank to the heater, wherein the heater and the water pump are mounted on top of the water tank, and in that the heater is a continuous-flow heater, comprising a water tube for guiding and heating of the water.
  • the steam generator being a modular unit achieves that it can be assembled as a co-joint or combined unit.
  • the heater and the water pump are mounted on the water tank.
  • the heater, the water tank, and the water pump may thus in particular be regarded as modules and may be manufactured separately and then co-joint or combined to form the steam generator as the single unit.
  • the modules may not constitute a distributed system wherein functional parts are only connected to each other by fluid channels like ducts.
  • the steam generator may thus be installed into the laundry appliance and removed from the laundry appliance substantially as a single unit. This allows an efficient and cost-effective assembly, installation and maintenance.
  • the heater and the water pump may or may not be directly attached to each other.
  • the heater and the water pump may in particular be mounted via one or more connection elements like screws or rubber holders, in particular screwed rubber holders.
  • the mounting may in particular not include an (indirect) attachment via a common base plate or such.
  • the heater is mounted on top of the water tank. This gives the advantage of a particular compact and reliable connection.
  • the water pump is mounted on the water tank. This also allows a compact and reliable connection.
  • a particularly compact steam generator is achieved by mounting the heater and the water pump on top of the water tank.
  • the heater is a continuous-flow heater.
  • the continuous-flow heater may in particular comprise at least one water tube for guiding and heating of the water flowing through it.
  • an NTC sensor is attached to the heater.
  • the NTC sensor which is characterized by including a resistor having a resistance which decreases upon increasing the temperature of the resistor (thus implying its nominative negative temperature coefficient) provides a very accurate and reliable temperature sensing.
  • the use of a NTC sensor provides a very accurate temperature measurement.
  • a NTC sensor is also particularly rugged. By mounting the NTC sensor on an outer surface of the heater, assembly is very easy. It may be noted that, other than prior art practice which generally relies on measuring a temperature of the water to be evaporated, the invention relies on measuring a temperature of the heater body directly. This temperature is much less affected by evaporation effects which limit the measurable temperature to the evaporation temperature of the liquid to evaporate. Accordingly, the invention guarantees a significantly higher precision in determining a true thermal overload of the heater.
  • a safety switch comprising a bi-metal element and a fuse is attached to the heater.
  • This safety switch provides a particularly reliable means to prevent overheating of the heater.
  • the safety switch may be attached to a bottom of the heater.
  • the heater is horizontally inclined. This embodiment achieves an improved de-calcification of the heater.
  • the water pump is a solenoid pump.
  • the water pump is mounted on the water tank using rubber holders, in particular screwed rubber holders. This allows suppressing a transmission of vibration generated by the water pump to other components of the appliance.
  • a pump outlet of the water pump and a water inlet of the heater are aligned horizontally and are facing each other. This ensures a direct and linear connection between the water inlet and the pump outlet that acts against a possible pressure drop at the heater and that also prevents a connecting hose from coming off.
  • the steam generator comprises a water level sensor comprising a reed sensor and a float sensor. This ensures a particularly reliable measurement of the water level within the water tank.
  • the water level sensor is placed inside the water tank.
  • the object is also achieved by a laundry appliance, wherein the laundry appliance comprises the subject steam generator.
  • This laundry appliance can be assembled and operated in an efficient and cost-effective manner.
  • the water tank is mounted on a heat exchanger cover of the laundry appliance. This position allows a stable positioning of the laundry appliance while at the same time allowing sufficient available space for the laundry appliance. Also, at this position the laundry appliance is easily accessible.
  • the laundry appliance comprises a condensate container shell, the condensate container shell sitting above the steam generator, wherein the condensate container shell is connected to the water tank by a de-aeration hose and/or a filling hose.
  • the de-aeration hose is a flexible hose.
  • the steam generator comprises a metal insert placed below the heater, wherein the heater is grounded to a dryer frame of the laundry appliance via the metal insert.
  • the metal insert may also act as a barrier against fire in case of a melting of the heater. This dual function of the metal insert leads to a reduction of components and reduces costs.
  • the laundry appliance comprises a steam separator to separate a mixture of water and steam output from the steam generator into the steam and water. This embodiment achieves that the refreshing and/or de-wrinkling function of the laundry appliance does not substantially deteriorate the drying effect.
  • the steam separator may thus comprise a combined water and steam inlet and two separate outlets for steam and water.
  • the water may be returned to a dryer pump reservoir of the laundry appliance.
  • a steam outlet of the steam separator is connected to a nozzle via a flexible hose, the nozzle being adapted to inject the steam and /or a fine mist of water droplets (in the following simply called steam) into a drum of the laundry appliance.
  • the nozzle achieves that the steam flow can be selectively orientated and injected deep into the drum. This leads to a greater efficiency of the refreshing and / or de-wrinkling function and / or to a saving of the amount of water used.
  • a hose in particular a flexible hose, between the steam separator and the nozzle allows a re-positioning of the nozzle without a major redesign. Further, the pressure at the nozzle can easily be adjusted by altering the characteristics of the hose, e.g. a diameter.
  • the nozzle is angularly shaped. This embodiment allows an inclined steam flow into the drum, in particular into a lower region of the drum and in particular directly onto the clothes, while at the same time a seat of the nozzle can remain vertical.
  • the laundry appliance is an appliance for drying laundry; even more preferred, the laundry appliance is a refresher dryer.
  • Fig.1 shows a refresher dryer 1 that is a clothes dryer 1 that incorporates a clothes or laundry refreshing and de-wrinkling function applying steam to the clothes.
  • the refresher dryer 1 is shown without housing.
  • the refresher dryer 1 is embodied as a tumble dryer 1 comprising a rotatable drum 2 which holds the clothes to be dried and which may be operated by being rotated in reversing rotational directions.
  • the drum 2 can be loaded and unloaded through an opening 3.
  • the opening 3 is typically closed by a door (not shown).
  • the operation of a tumble dryer 1 as such is well known.
  • the refresher dryer 1 comprises a steam generator 4 which is located at a bottom of the refresher dryer 1 and mounted on top of a cover 39 of a heat exchanger 40. Of the steam generator 4, a front side F (see also Fig.2 ) is visible.
  • the steam generator 4 is used to generate steam from water. Water is supplied to the steam generator 4 via a condensate container shell 5 through a flexible filling hose 6. The water supplied to the steam generator 4 is thus the condensate that is extracted from the damp clothes during the drying process.
  • the condensate container shell 5 may additionally be filled by fresh water, e.g. at the beginning of a drying cycle if there is not yet enough condensate to supply the steam generator 4.
  • the output generated by the steam generator 4 usually is a mixture of steam and hot water and is led to a steam separator 7.
  • the steam separator 7 separates the steam from the hot water.
  • the steam is fed into the drum 2 via a hose 8 that leads to a nozzle 9.
  • the nozzle 9 opens into the drum 2 and may inject the steam directly onto the laundry to be treated therein.
  • the steam injection may comprise an injection of steam and/or a fine mist of water droplets.
  • the nozzle 9 may have a shape (e.g. angular shape) that allows orientation of the steam flow.
  • the hot water is returned to a T-connector 42 located in a dryer pump reservoir via a flexible hot water return hose.
  • the steam separator 7 ensures that only steam with a low or very low liquid content is fed into the drum 2.
  • the steam generator 4 further comprises or is connected to a flexible de-aeration hose 43 that connects to a water tank (see Fig.3 for further detail) of the steam generator 4.
  • the steam generator 4 further comprises a siphon fixation 47 for holding or fixing a siphon 48.
  • Fig. 2 shows the steam generator 4 in greater detail.
  • Fig. 2 shows an elevated view onto a rear side B of the steam generator.
  • the rear side B of the steam generator 4 borders on the drum 2 and faces to the inside of the refresher dryer 1 of Fig.1 .
  • the front side F of the steam generator 4 is shown in Fig.1 .
  • the steam generator 4 comprises a water tank 10 for a base that is covered by an upper part 11 of a tank body of the water tank 10.
  • a water level of the water tank 10 is measured by a water level sensor 12 that is implemented as a combined reed water level sensor 12a and float water level sensor 12b.
  • the water level sensor 12 is placed inside the water tank 10.
  • the water tank 10 is filled with water via a water inlet 19 that is connected to the filling hose 6 as shown in Fig. 1 .
  • the water level sensor 12 may be used to control the function of the steam generator 4 as well as the function of drying components of the refresher dryer 1; in this case the water tank also acts as a water tank for the drying components.
  • the heater 13 On top of the upper part 11 of the water tank 10 is (directly) mounted or fixedly attached a heater 13 to heat water and subsequently produce steam, usually mixed with the hot water.
  • the heater 13 comprises an aluminium housing and is supported on support columns 21. Further, the support columns 21 each hold a respective silicone holder 23 laterally mounted to the heater 13. This holding or supporting arrangement of the heater 13 has the advantage that vibrations from or to the heater 13 are suppressed and that a thermal flow from the heater 13 is at least partially blocked by the silicone holders 23.
  • the heater 13 is not arranged horizontally but is angled relative to the horizontal in order to achieve an improved de-calcification.
  • the mixture of steam and hot water generated within the heater 13 is led out of the heater 13 and fed to the steam separator 7 by a steam outlet pipe 15 or hose.
  • a temperature of the heater 13 is monitored by a NTC (negative temperature coefficient) sensor 16 that is mounted on top / on an upper part of the heater 13.
  • the NTC sensor 16 may be regarded as part of the heater 13.
  • the heater 13 also comprises or is connected to a safety switch 17 by which the heater 13 may be switched off to prevent overheating.
  • the water is supplied from the water tank 10 to the heater 13 by a water pump 14 which is implemented as a solenoid-driven vibration pump.
  • the solenoid water pump 14 is supported by a pair of screwed rubber holders 18 that directly mount the water pump 14 to the upper part 11 of the water tank 10. This reduces the propagation of vibration and thus reduces the overall noise of the steam generator. The suppression of the vibration propagation also enhances the life time of the steam generator 4.
  • Fig. 3 shows an exploded view of the steam generator 4 viewing its front side F.
  • the water tank 10 comprises a tank body 20, which is covered by the upper part 11.
  • the upper part 11 comprises the water inlet 19 and a de-aeration outlet 44 for connection with the de-aeration hose 43.
  • the tank body comprises a water outlet 45 that can be connected to a water inlet of the water pump 14 via a water pipe 46.

  • the bottom of the tank body 20 also holds the siphon fixation 47.
  • the upper surface of the water tank 10 further comprises the support columns 21 for supporting the heater 13.
  • the support columns 21 each comprise an upper recess 22 for supporting the respective silicone holder 23.
  • Each silicone holder 23 is in turn laterally mounted to the heater 13, in particular fitted onto a respective mounting column 24.
  • This holding arrangement of the heater 13 has the advantage that vibrations from or to the heater 13 are suppressed and that a thermal flow from the heater 13 is at least partially blocked by the silicone holders 23.
  • Water is supplied into the heater 13 via a water inlet connection 27, is guided within the heater 13 by a water tube 38 and can then leave the heater 13 as steam or a mixture of hot water and steam by a steam outlet connection 28 (this equals the heater 13 to be a continuous-flow heater).
  • the water tube 38 can be heated up by a heating element or heating elements (not visible) of the heater 13.
  • the water tube 38 is located on a top surface of the heater 13.
  • the water inlet connection 27 is connected to a pressure outlet 29 of the water pump 14 by a connection hose 30.
  • the water inlet connection 27 and the pressure outlet 29 are aligned horizontally and facing each other; this ensures a direct /linear connection that acts against a possible pressure drop at the heater 13 and that also prevents the hose 30 from coming off.
  • the steam outlet connection 28 is connected to the steam outlet pipe 15.
  • the heater 13 is angled relative to the horizontal with the end comprising the connections 27, 28 being placed lower than the opposite end in order to achieve an improved de-calcification.
  • metal insert 25 with soft edges, e.g. round edges.
  • the soft edges prevent damage to electrical connections, e.g. damage to an insulation of an electrical cable.
  • the heater 13 is grounded electrically via the metal insert 25 and from the metal insert 25 further to a dryer frame 33 shown in Fig.1 .
  • the metal insert 25 may act as a barrier against fire in the unlikely case of a melting of the heater 13.
  • the NTC sensor 16 On top of the heater 13 is mounted the NTC sensor 16. Electrical terminals 26 of a heating element of the heater 13 are located at the same side as the water inlet and outlet.
  • the safety switch 17 uses a duo pack comprising a bi-metal element and a fuse to prevent overheating of the heater 13. In case that the safety switch 17 detects an overheating condition, it switches off the heater 13. Threshold temperatures where a switching action will occur are presently set at 190°C for the bi-metal element which is reversible, and 260°C for the fuse which is irreversible. Thereby, the safety switch 17 will turn off heater 13 reversibly in case of a minor malfunction which produces a temperature rise of minor criticality, and it will turn off heater 13 irreversibly (that is, irreversibly except by action of a skilled service technician) upon a temperature rise of major criticality.
