Description
DESCRIPTION
A HEAT PUMP LAUNDRY DRYER
The present invention relates to a laundry dryer comprising a heat pump that dehumidifies and heats the process air. In laundry dryers, the lints that come off the laundry in the drying process mix with the process air enabling the drying process and adhere on components like the heat exchanger, fan and decrease the drying efficiency. Lint filters are situated on the air channel for collecting the lints. In this situation, the lint filter is clogged in the course of time and the filter has to be cleaned. The lint filter that is not cleaned in time hinders the flow of the process air and since the heated process air cannot pass over the laundry, it cannot be cooled and the temperature rises in the air channel. In this case, the overheated compressor changes into standby mode for protection. The compressor in the standby mode operates again after cooling down and the total duration of the drying process increases since the laundry cannot be dehumidified meanwhile. Embodiments are known, wherein water is passed over the lint filter for cleaning during the drying process. However, in these embodiments, a water wall forms on the filter that hinders the flow of the process air while the filter is washed and washing the filter during the drying process cannot completely solve the above mentioned problem.
In the state of the art International Patent Application No. WO2014102073, a laundry dryer is disclosed, that comprises a variable speed compressor.
In the state of the art International Patent Application No. WO2014102073, a laundry dryer is disclosed, that comprises a compressor, the operating speed of which is changed depending on the temperature.
The aim of the present invention is the realization of a laundry dryer, the drying effectiveness of which is increased.
The laundry dryer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a control unit that regulates the operational speed of the compressor performing the refrigerant cycle depending on the operation of a washing means that provides the spraying of water onto
the lint filter during the drying process and that decreases the operational speed of the compressor while the washing means operates. The control unit determines the operational speed of the compressor depending on the operation duration of the washing means so that the compressor does not change into standby mode by overheating and when the washing means operates, decreases the operational speed of the compressor. Thus, the compressor is enabled to continue operating without being affected by the water wall formed on the filter while the filter is being washed.
In an embodiment of the present invention, the control unit decreases the operational speed of the compressor just before the washing means sprays water onto the lint filter and operates the compressor in low speed during the operation duration of the washing means. By operating the compressor at lower speeds, when the process air flow rate decreases while the filter is being washed, the compressor is aimed to continue operating without being affected from this situation.
In another embodiment of the present invention, the control unit increases the operational speed of the compressor just after the washing means completes water spraying operation onto the lint filter. By means of this embodiment, the operational speed of the compressor is increased after the water wall on the filter is drained so that the drying duration is not prolonged and the laundry is enabled to be dried faster.
In another embodiment of the present invention, the washing means sprays water onto the lint filter at predetermined intervals during the drying process and the control unit decreases the operational speed of the compressor step by step between two operational stages of the washing means. During the drying process, lints continuously accumulates on the filter. The lints accumulated on the filter affects the flow rate of the process air. When the filter is clean and the flow rate is high, the process air flow rate decreases as lints accumulate on the filter. The control unit operates the compressor in line with the flow rate of the process air by gradually decreasing the operational speed of the compressor between two operational stages of the washing means. Thus, the compressor is prevented from overheating.
In another embodiment of the present invention, just after the washing means completes the operation of sprays water onto the lint filter, the control unit changes the operational
speed of the compressor to the previous operational speed, that is before the washing means sprays water onto the lint filter. By means of this embodiment, the compressor is operated at low speed only when the washing means operates, at other times is operated at high speed and provides the completion of the drying process in a time as short as possible.
In another embodiment of the present invention, the laundry dryer comprises a fan that provides the cooling of the compressor by blowing air thereon and the control unit operates the fan while the washing means sprays water onto the lint filter. The compressor is enabled to be cooled by the fan, thus prevented from changing into the standby mode by overheating. In a version of this embodiment, the control unit increases the operational speed of the fan when the washing means is operated and provides the realization of a more effective cooling.
By means of the present invention, accumulation of lint in the air channel is prevented and the compressor is enabled to operate incessantly during the drying process without changing into the standby mode such that the duration of the drying process is not prolonged. Thus, the drying duration is optimized and the drying efficiency is increased.

In the laundry dryer (1), the lints that come off the laundry are collected on the filter (4). The washing means (5) enables the filter (4) to be cleansed of the lints accumulated thereon by preferably spraying pressurized water onto the filter (4) at certain intervals during the drying process. The compressor (7) pressurizes and delivers the refrigerant fluid to the heat exchanger (6) and the refrigerant fluid that passes through the heat exchanger (6) returns to the compressor (7) by completing its cycle and this cycle is repeated during the drying process.
The laundry dryer (1) of the present invention comprises a control unit (8) that controls the operation of the washing means (5) and enables the rotation speed of the compressor (7) to be decreased while the washing means (5) is operated. The control unit (8) controls when and how long the washing means (5) is operated during the drying process. The control unit (8) decreases the rotation speed of the compressor (7) depending on the operation state of the washing means (5) and prevents the compressor (7) from stopping due to the water wall formed on the filter (7).
In an embodiment of the present invention, the control unit (8) provides that the rotation speed of the compressor (7) is decreased a certain time period predetermined by the producer before the washing means (5) is operated and that the compressor (7) is continued to be operated at low rotation speed during the operation of the washing means (5).

The rotation speed of the compressor (7) is increased when the filter (4) is cleaned by the washing means (5) and the process air (PA) flow returns to normal. In another embodiment of the present invention, the control unit (8) changes the rotation speed of the compressor (7) to maximum after the washing means (5) is operated and the filter (4) washing operation is completed, that is after the washing means (5) is deactivated. Thus, when the filter (4) is cleaned and the process air (PA) is enabled to flow at high rate, the compressor (7) is operated at maximum rotation speed and the duration of the drying process is shortened.
In another embodiment of the present invention, the control unit (8) decreases the rotation speed of the compressor (7) gradually between two operation stages of the washing means (5). The producer determines the operation frequency of the washing means (5), that is in what time duration the filter (4) becomes clogged so as to affect the drying process, as a result of experiments conducted and saves the operation frequency of the washing means (5) depending on the weight and type of the laundry loaded in the memory of the control unit (8). The filter (4) is clogged increasingly between two operational stages of the washing means (5) and this situation affects the flow rate of the process air (PA). The control unit (8) prevents overheating of the compressor (7) by gradually decreasing the operation speed of the compressor (7) proportionally to the
decrease in the flow rate of the process air (PA) between two operational stages of the washing means (5).
In another embodiment of the present invention, after the washing means (5) is deactivated, the control unit (8) changes the rotation speed of the compressor (7) to its previous rotation speed before the washing means (5) was operated.
