Definitions

  • the invention relates to a method for operating a washer dryer with protection against thermal shock and a suitable washer-dryer. More particularly, the invention relates to a method of operating a washer dryer, wherein the washer dryer comprises a tub; a rotatably mounted in the tub drum with a closable glass door, the drum is used for receiving and removal of laundry with the glass door open; a control device and a process air duct in which a heater for heating air, a blower, and at least one temperature sensor for measuring a temperature T pc are.
  • the invention also relates to such a washer-dryer.
  • Washer dryers are popular because they combine the functions of a washing machine and a tumble dryer in a single device in a space-saving manner.
  • a washer-dryer is already provided with a water connection, so that water is not only available for washing laundry, but also for further treatment of laundry items.
  • thermo shock resistance is the maximum possible temperature difference, when used as a thermal shock, there is no bursting of the glass.
  • soda-lime glass generally used for corresponding access doors can no longer be used if it is to be possible that there is a rapid transition between a high temperature process air drying process and a cold water washing process and the temperature difference is 100 Kelvin or more. This can be remedied by the use of borosilicate glass. This is expensive.
  • High surface temperatures in a washer dryer can also pose a danger to a user.
  • the user's operation of the washer-dryer i. in the closed state of the access door, facing outside of the door glass often protected by an additional disc of glass or plastic.
  • an additional disc of glass or plastic In addition to protection against too high a surface temperature, in particular protection against cold shock caused by cold water, if possibly cold water would reach the outside of the access door.
  • a temperature shock can be caused by cold water that reaches the inside of the glass door. This is e.g. the case when a washing program is started by introducing cold water immediately after or during a drying process. Then cold water can be injected from the inside against the glass door or be transported through the laundry items from the bottom of the tub to the glass door.
  • the EP 2 636 788 A1 describes a clothes dryer comprising: a drum moving laundry items, a window glass openably disposed in front of the drum; a blower unit which sends dry air; a dehumidifying unit which dehumidifies the drying air discharged from the drum; a heating unit which heats the dehumidified drying air; a first air passage with a first air outlet, which is opened at a rear end of the drum to blow the drying air into the drum; a second air passage having a second air outlet opened in front of the drum for blowing the drying air into the drum; an air passage switching unit that selectively switches between the first and second air passages; a temperature detecting unit which detects a temperature of the window glass; and a control unit, wherein the control unit performs control such that switching is selectively performed between the first air passage and the second air passage by the air passage switching unit when the detection result of the temperature detecting unit reaches a first predetermined temperature. This is to ensure that items of laundry in the drum are not dried inconsistently
  • the EP 2 636 788 A1 also states that after a drying process, the high temperature glass door must be cooled before the dried laundry can be removed from the dryer. For this purpose, it is known to carry out a cooling process in order to cool a window glass. To EP 2 636 788 A1 For example, it is possible to operate the laundry dryer in which laundry items may be dried while at the same time controlling the temperature of the window glass so as to maintain a predetermined temperature at which the glass is not too hot for a user.
  • the CN 1521313 A describes a washer-dryer with a guide tube which guides the hot process air so that it does not come into direct contact with the glass door of the washer-dryer. This is to prevent damage to the glass door due to abrupt temperature changes and scalding a user of the washer dryer.
  • the DE 10 2012 207 742 A1 describes a method for operating a dryer with a program control, a drum for laundry to be dried, a process air duct in which a process air blower for conveying the process air and a heater for heating the process air, and with a variable speed drive motor, the drum and the process air blower drives, wherein the method comprises a heating phase, a quasi-stationary drying phase and a cooling phase, wherein in the quasi-stationary drying phase of the variable-speed drive motor is operated at a mean speed ⁇ 1 and the process air blower with a mean speed ⁇ 1 , and during the cooling phase at least temporarily the variable-speed drive motor with a speed ⁇ 2 is less than ⁇ 1 and the process air fan is operated at a speed ⁇ 1 .
  • the method is operated so that a maximum allowable temperature T max of the process air is not exceeded.
  • the object of the invention was to provide a method for operating a washer-dryer with improved protection against temperature shocks.

  • step (b) the cooling program is performed when T pc 1 > T pc lim .
  • the temperature sensor is located directly on the glass door or in its immediate vicinity, then it can directly measure the temperature of the glass door. However, it is also possible to use a temperature sensor that is significantly removed from the glass door. In such a case, before the measurement, the blower of the process air for a certain period .DELTA.t blow can be turned on to effect a temperature compensation along the process air duct and thus to ensure that the temperature sensor provides a signal significant for the temperature of the glass door.
  • the period .DELTA.t blow may not exceed a length of one minute and in particular be about 30 seconds.
  • the temperature of the glass door is measured with a temperature sensor T3 attached directly to it, an immediately suitable measured variable is available at any time in order to decide whether an additional cooling step has to be carried out. If the corresponding temperature sensor T1 or T2 is not located directly on the glass door, the temperature of the glass door can be determined indirectly by operating the process air blower for a short period of time, which in particular lasts less than one minute, preferably for about 30 seconds, prior to the detection of a measured value becomes. As a result, a uniform temperature distribution in the process air duct is advantageously achieved, so that the temperatures of the process air measured by the temperature sensors, for example T1 or T2, can be used as a representative measure of the temperature of the glass door.
  • the upper limit temperature T pc lim is to be selected as a function of the shock temperature ⁇ T shock corresponding to the material of the glass door.
  • T W-min can be set at 3 ° C, for example, in Central Europe.
  • it is also possible to determine the temperature of the available fresh water T aq in a particular case by means of a correspondingly provided temperature sensor and then determine the relevant for this particular case upper limit temperature as T pc lim T aq + ⁇ T shock .

That is, in the method according to the invention in particular when reaching or exceeding the temperature T pc lim the process air is cooled. By applying the cooled process air then a cooling of the glass door can be achieved.
