Definitions

  • the invention relates to a tumble dryer according to the preamble of claim 1.
  • Dryers of this type in which the condenser and the evaporator of a heat pump cycle are used for cooling and heating, are characterized by a high efficiency. It turns out, however, that they have to be deprived of heat, otherwise the temperature in the heat pump cycle can rise to high levels.
  • the object of the present invention is the improvement of such a device. This object is achieved by the device according to claim 1.
  • the additional heat exchanger is thus arranged in the heat pump cycle between the condenser and the throttle body. At this point, the temperature of the medium is relatively high, which improves the efficiency of the additional heat exchanger. In addition, the temperature difference between evaporator and condenser is increased by the additional heat exchanger, which makes it possible to extract more water from the process air.
  • the device has a drum 1 for receiving the laundry to be dried. It is a process cycle provided (which is shown in Fig. 1 by solid lines), in which heated process air passed through the drum 1, then cooled and then reheated and fed back into the drum 1.
  • an optional additional electrical heating (starting heating) 9 can be provided, which allows heat to be specifically supplied to the process air, e.g. when starting the device, or it can be used to raise the temperature level in the process cycle in general.
  • a blower 10 serves to pump over the process air.
  • a heat pump cycle is provided (wherein the path of the pumped by the heat pump cycle medium in Fig. 1 is shown with dotted lines).
  • the medium is conveyed from a compressor 2 to a condenser 3, from there to an additional heat exchanger 4, then via a throttle means 5, e.g. in the form of capillaries or an expansion valve, to an evaporator 6 and then back to the compressor 2.
  • the evaporator 6 serves to cool the process air and thus to extract water while the condenser 3 serves to reheat the process air so that she can absorb new water.
  • a fan 7 is provided, with which ambient air is passed through the additional heat exchanger 4 in order to cool it.
  • the additional heat exchanger 4 is used to extract heat from the heat pump cycle and thus the entire system.
  • the amount of heat extracted is controlled depending on the temperature in the heat pump cycle (and / or depending on the temperature in the process cycle), e.g. by operating the blower 7 with greater power as the temperature rises.
  • the fan can be turned on only when the temperature exceeds a predetermined threshold.
  • the power of the fan 7 is continuously increased with increasing temperature.
  • the temperature-dependent control of the fan 7 allows, e.g. When starting the tumble dryer to supply energy to the process cycle very quickly, so that the process temperature is reached quickly, after which overheating of the heat pump cycle is prevented in normal operation.
  • the temperature of the running in the heat pump cycle medium after the additional heat exchanger 4 and before the throttle body 5 is used to control the fan 7.
  • the device For driving the fan 7, the device has a suitably designed control and suitable temperature sensors 40, 41. Preferably, at least the temperature T1 at the inlet of the throttle body 5 is measured.
  • the present invention can be used independently of the medium used in the heat pump cycle.
  • the embodiment described below works, for example, with R134a, the same principle can be used with appropriate dimensioning but also eg in a CO 2 cycle.
  • FIGS. 2 to 5 is a tumble dryer having a drum 1 that can be fed from the front.
  • a (not shown in the figures) drive provided with which the drum can be rotated about a horizontal axis of rotation.
  • the process air passes from the interior of the drum in a known manner through a sieve or sieves in the door (not shown) of the device and / or after the door and then passes through the evaporator 6, the condenser 3, the fan 10 (see FIG. 3), the optional auxiliary heating (starting heating) 9 and is passed through holes 11 in the rear wall of the drum 1 back into the drum.
  • the process air passes from the interior of the drum in a known manner through a sieve or sieves in the door (not shown) of the device and / or after the door and then passes through the evaporator 6, the condenser 3, the fan 10 (see FIG. 3), the optional auxiliary heating (starting heating) 9 and is passed through holes 11 in the rear wall of the drum 1 back into the drum.
  • a channel housing 12 see FIG. 2.
  • the heat pump cycle is located at the bottom of the unit and is best seen in FIGS. 4 and 5.
  • the floor area is divided into two adjacent areas 14 and 15, each of which extends from the front 16 of the appliance to the rear 17 thereof.
  • the additional heat exchanger 4, the evaporator 6 and the condenser 3 can each be constructed of identical modules.
  • Each module has a meandering tube which is in thermal contact with a plurality of heat exchanger plates 20. Of the heat exchanger plates only the outermost are shown in the figures. The process air or the ambient air is guided through the gaps between the heat exchanger plates.
  • the condenser 3 consists of three modules, the evaporator 6 of two modules and the additional heat exchanger 4 of only one module.
  • the number of modules can be adapted to the respective requirements.
  • the additional heat exchanger 4 may also comprise two or more modules, which can be traversed sequentially or in parallel by the medium of the heat pump cycle.
  • the ambient air is sucked in by the first fan 18, via a suction port 22 in the base 23 at the front of the device (see Fig. 2).
  • the air passes to the additional heat exchanger 4, then to the compressor 2 and then to the second fan 19.
  • An over the additional heat exchanger 4 arranged air guide molding 25 serves to the air in the region of the additional heat exchanger 4 to lead.
  • an air guide 26 is provided which guides the air under the (not shown) behind the second fan 19 arranged drive the drum 1 through to ventilation openings 27 on the back 17 of the device. Additional vents may be provided in the bottom of the device.
  • the ambient air is passed through the compressor 2, this can also be cooled.
  • the cold ambient air is first passed over the additional heat exchanger 4, as a larger amount of heat can be dissipated via this.
  • the ambient air flows through the additional heat exchanger 4 from front to rear, while the medium of the heat exchanger circuit first passes through the rear side of the additional heat exchanger 4 and then only the front side, so that the additional heat exchanger 4 is hotter on the rear side than on the front side.
  • the efficiency of the cooling can be improved.
  • the medium of the heat pump cycle runs from the compressor 2 via a pipe 30 to the condenser 3 and from there via a pipe 31 to the additional heat exchanger 4. From the additional heat exchanger it runs via the throttling element 5 designed as a capillary to a branch 32, from where it is in the present embodiment is performed in parallel in two paths through the evaporator 6. From the evaporator 6, the medium passes through a pipe 33 back to the compressor. 2
  • the ambient air is sucked through an opening 22 on the front 16 of the device, then passes through the first fan 18, then the additional heat exchanger 4, then the compressor 2 and finally by the second fan 19.
  • the suction of the air from The front 16 has the advantage that the sucked air is relatively cool, so that a good cooling of the additional heat exchanger 4 can be achieved.
  • Conceivable is also a suction of ambient air from the back and / or bottom of the device ago, or the ambient air can be sucked in by openings on the side wall of the device, as far as there ensures sufficient distance to adjacent walls or other devices is.
  • the first fan 18 is larger and promotes more air than the second fan 19. This means that a portion of the air does not go back to the outside via the second fan 19, but the device via ventilation openings 29 in the upper part of the rear wall steps outside. On its way to the ventilation openings 29, this air can additionally cool other parts of the appliance, e.g. the drum 1.
  • the second fan 19 was used to blow air back from the compressor 2 forth to the outside. In a further preferred embodiment, however, the second fan 19 is operated so that it also blows ambient air into the interior of the device. This has the advantage that the compressor 2 is blown by two sides approximately opposite each other and thus better cooled. In this case, the air from the two fans 18, 19 can additionally cool other parts of the appliance, e.g. Drum 1, and then e.g. exit through the ventilation openings 29 in the upper part of the rear wall again.
  • both fans 18, 19 are controlled depending on the temperature in the heat pump cycle and / or process cycle. It is also conceivable, however, a separate control depending on the local temperature in the associated device areas.
  • the blower 7 is preferably operated at a higher power when the temperature rises.
  • This increase can be stepless or in steps.
  • the table shows the amount of cooling air as a percentage of the volume flow of the delivered air volume relative to the maximum amount of air that can be conveyed by the ventilation 7.
  • a temperature sensor 40 for measuring the temperature T1 can be arranged in front of the throttle element 5, as illustrated in FIG.
  • the above table is to be understood as an example.
  • the gradation may also be coarser or finer, or a continuous dependence between flow rate and temperature may be used.
  • a multi-stage dependency or a continuous dependency allows a finer control of energy extraction than a "binary" on-off control. It turns out that this process can shorten the process time by a few minutes.
  • step changes are preferably not made arbitrarily fast, but e.g. at most once a minute.
  • the ventilation or the fan can be operated continuously with reduced power after the start of the drying program.
  • the tumble dryer is thus designed so that during the drying process, the fan can be operated continuously on at least a first power level, wherein the power level is increased gradually or continuously as the temperature increases in the heat pump cycle.
  • an AC motor is used to drive the fan or ventilation 7, it is preferably pulsed by a zero-crossing switch (or by a zero-crossing control, ie a zero-crossing switch controlled by a control or regulation). driven.
  • zero-crossing switches are known to the person skilled in the art. They interrupt and activate the supply of the motor at the zero crossing of the current or the voltage. By supplying power to the motor by means of a zero-crossing switch with pulses of different length or duty cycle, it can be varied in steps. In contrast, for example, to control via a phase control circuit, an unwanted noise can be avoided by this measure. Conceivable, but more expensive, is also a control of the AC motor via AC voltages of different heights, for example via multiple transformer taps.
  • the power of the blower 7 or the fan 18 and / or 19 is preferably controlled as a function of the temperature upstream of the throttle element 5.
  • An improved variant of such a control is illustrated in FIG. This is based on the consideration that it is also possible by appropriate control of the fan power to prevent condensing of the medium upstream of the compressor 2.
  • a partial or even complete condensation of the medium in front of the compressor can take place if the temperature T2 is too low at this location and at the same time a relatively high pressure prevails. It is undesirable because it can lead to damage of the compressor 2.
  • the power of the fan 18 and / or 19 is as possible regulated so that the heat pump cycle less energy is withdrawn, if a condensation threatens.
  • a second temperature sensor 41 is provided, with which the temperature T2 after the evaporator 6 and in front of the compressor 2 can be measured, in particular as close as possible in front of the compressor 2. The control of the fan power takes place in this Case depending on the temperatures T1 and T2.
  • control of the fan power is dependent on T1 and of the temperature difference T1 - T2.
  • performance of the ventilation is increased depending on how much the temperature T1 is above the reference temperature T0.
  • the reference temperature T0 is set depending on the course of the temperature difference T1 - T2. It can be seen that the temperature difference T1 - T2 is a good measure for comparison with the temperature T2 to determine whether there is a risk of condenser out of the medium.
  • Fig. 6 a typical drying process of a preferred embodiment of the invention is shown.
  • the upper curve represents the output of the blower 7, while the lower curves represent the different temperatures T1, T2 and T1-T2, and the evaporation temperature Tv of the medium between the evaporator 6 and the compressor 2.
  • the evaporation temperature Tv was calculated from the temperature T2 and from a measurement of the measured pressure of the medium between evaporator 6 and compressor 2. (The determination of the evaporation temperature Tv was carried out as part of a laboratory experiment - in normal operation of a device according to the invention Tv does not need to be determined.)
  • the temperature T1 is compared with the reference temperature T0 and the power of the fan 7 is gradually increased in the manner shown in the above table, the more the temperature T1 exceeds the threshold T0.
  • the reference temperature T0 is 64 ° C. As soon as the difference temperature T1-T2 becomes greater than the temperature T2, the reference temperature T0 is increased by a predetermined offset of, for example, approximately 15 ° C., for example to 79 ° C. In the example of FIG. 6, this is the case for the first time at time t1.
  • the reference temperature T0 is maintained at the higher value until the condition T1-T2 ⁇ T2-H is satisfied, where H is a hysteresis value of e.g. 10 ° C is. This is the case in FIG. 6 for the first time at the time t2. Then the reference temperature T0 is lowered again to the lower value, whereby the cooling is intensified. As soon as T1 - T2> T2 (time t3), the reference temperature T0 is reset to the higher value. This process repeats itself (in FIG. 6 at the times t4 and t5) whenever the threshold conditions T1-T2 ⁇ T2-H or T1-T2> T2 are traversed.
  • the temperature T2 always lies above the evaporation temperature Tv, so that condensation of the medium remains prevented. Thus, it can be ensured by comparing the difference T1 - T2 with the temperature T2 that no subcooling of the medium takes place before the compressor 2.
  • the sequence according to FIG. 6 is controlled by the already mentioned controller of the device, which evaluates the signals of the temperature sensors T1 and T2, determines the reference temperature T0 and controls the power of the fan 7.
  • T1-T2 is an indicator of evaporation temperature
  • T2 is a measure of how close the system is to low refrigerant superheat. The measure works particularly well in the present case, since T1 is regulated to a practically fixed value.
  • T2 the temperature difference between T2 of the temperature in the center of the evaporator or by determining the pressure in the area of the evaporator.
