Description
- The present invention relates to a system for detecting the level of condensation collected in a laundry dryer appliance, wherein the laundry dryer appliance may be of the type comprising a housing with a front loading port, a laundry rack received in the housing and suitable for receiving the laundry to be dried, as well as a "closed" drying circuit, with a suction unit, a heat exchanger and a heating unit with electrical resistors, configured for conveying a flow of heated and dry air through the laundry rack.
- In such drying circuit known as closed circuit, the air flow caused by the suction unit is heated by the electrical resistors and conveyed into the rack, where crossing the wet laundry, it causes the evaporation of the water contained in the fabric. In the heat exchanger, the humid air is cooled, for example by a flow of cold water or by a flow of cool air. By the effect of cooling, the steam condensates and is collected in a condensation collecting container. The dehumidified air is then sucked in again by the suction unit and made to circulate.
- In laundry dryer appliances with condensation collection without automatic discharge it is important to know the filling level of the condensation collecting container in order to influence the control of the laundry dryer appliance so as to prevent an overflow of the collecting container and consequent damages to the household appliance and prevent water damages to the apartment or house where it is installed.
- Laundry dryer appliances of the type mentioned above are known, provided with a drawer-like extractable condensation collecting container and a pressure switch level sensor in fluid communication with the inside of the collecting container, wherein the pressure switch sensor is configured for activating (for example for switching an electrical control circuit) upon reaching a threshold pressure value that corresponds to a threshold filling value of the condensation collecting container.
- Such known solution is expensive, complex and difficult to install since the pressure switch sensor must be exposed to the condensation pressure on the bottom of the collecting container but the electrical control circuit must be isolated from the condensation itself.
- Moreover, the use of a contactless sensor is known, for example a Reed switch that is activated by a magnet supported by a float arranged in the condensation collecting container.
- While the magnetic switch is less expensive than a pressure switch detector, due to the uneven magnetic field, the condensation level detection results in the collecting container are not always sufficiently accurate and therefore, the magnetic switch must be calibrated to a "safe" threshold level which is lower than the maximum filling level. As a consequence, the collecting container must be filled more often than what strictly required. Moreover, the arrangement of the float with the permanent magnet inside the collecting container reduces the volumetric capacity thereof, the overall dimensions being the same, further increasing the emptying frequency thereof.
EP1816252 A1 describes a laundry dryer appliance which is considered a closest state of the art for the present invention. - The aim of the present invention therefore is to provide a system for detecting the condensation level in laundry dryer appliances, having such features as to obviate at least some of the disadvantages mentioned with reference to the prior art.
- A particular aim of the present invention is to propose a laundry dryer appliance with a more accurate and repeatable system for detecting the condensation level.
- This and other aims are achieved by a laundry dryer appliance comprising a housing with a loading port, a laundry rack received in the housing and suitable for receiving the laundry to be dried, a drying circuit with a heat exchanger, an extractable container for collecting the condensation and a sensor for detecting a threshold level of the condensation inside the collecting container, wherein the sensor comprises:
- a float carrying a permanent magnet, the float being arranged in a guided manner in fluid communication with the inside of the collecting container;
- a magnetically susceptible switch, in particular a Reed switch positioned and configured for being actuated by the permanent magnet upon reaching the condensation threshold level,
- This allows a precise positioning and orientation of the permanent magnetic field relative to the focal point of magnetic sensitivity of the
Reed switch 14 and thus, a more accurate and repeatable detection of the moment in which the threshold level of the condensation collected incontainer 10 is reached. - To better understand the invention and appreciate the advantages thereof, some exemplary non-limiting embodiments thereof are described below with reference to the annexed drawings, wherein:

container 10 and maximising the volumetric capacity of the collecting container, the overall dimensions being the same. Themeasurement space 15 may advantageously be formed in a zone of the housing not used or usable for other purposes. - According to an embodiment, the
measurement space 15 is in fluid communication with afirst connector 18 arranged at thecontainer space 16 and provided with afirst locking valve 17.

collecting container 10 is extracted from thecontainer space 16 or inserted in an incomplete manner, themeasurement space 15 remains isolated from the outside and retains any accumulated condensation. On the other hand, during and after the extraction of the collectingcontainer 10 from thelaundry dryer appliance 1, thesecond connector 19 is closed and allows an easy handling without any risk of liquid spilling, which can be easily poured through an emptying opening 21 (separate from the second connector 19) closable by a threaded cap and having a relatively large opening section. - According to the invention,

switch seat 24 comprises twoside guides 26 having an L shaped section and protruding from atop surface 27 of thefixing plate 23opposite guide 25, anabutment tooth 28 protruding from thetop surface 27 and defining a position reference forswitch 14 which is received and guided by theside guides 26, as well as anelastic tab 29 also protruding from thetop surface 27 and positioned opposite theabutment tooth 28 with reference to the target position ofswitch 14, so as to allow the insertion ofswitch 14 into theswitch seat 24 and prevent an extraction or accidental or undesired loss thereof (Figures 2 and 3 ). - According to an embodiment, at least one of the
side guides 26 may comprise a yieldingappendix 30 that, whenswitch 14 is inserted in theswitch seat 24, engages acorresponding shoulder 31 ofswitch 14 so as to bias switch 14 elastically in abutment against theabutment tooth 28 and thus ensure the correct positioning thereof. - In accordance with an embodiment, the
permanent magnet 13 is at least partly or entirely encapsulated in the plastic material offloat 12. - As an alternative, the
permanent magnet 13 is received by snap-wise coupling in amagnet seat 32 offloat 12. - Advantageously, the
same magnet 13 may exhibit a cylindrical or discoid or cylindrical pad shape and defines a magnetic axis M and two magnetic poles N, S of opposite sign respectively arranged at two opposite ends ofmagnet 13 along the magnetic axis M and whereinmagnet 13 is oriented with the magnetic axis M thereof substantially perpendicular to the sliding axis V offloat 12 and both magnetic poles N, S exhibit the same axial distance DV (with reference to the sliding axis) from switch 14 (Figure 9 ). This allows a precise positioning and orientation of the permanent magnetic field relative to the focal point of magnetic sensitivity of theReed switch 14 and thus, a more accurate and repeatable detection of the reaching of the threshold level of the condensation collected incontainer 10. - According to an embodiment (
