Definitions
- the present invention relates to a laundry washing and drying machine comprising an air-cooled condenser.
- air-cooled condensers are widely used, that realize the condensation process by using the outer environment air in the drying process after the washing step.
- Humid air that comes from over the laundry and passes through the processing air channel is condensed in the condenser cooled by means of the outer environment air, thus the air that is dried by being dehumidified is sent again onto the laundry through the processing air channel.
- the condensation process realized in the air-cooled condenser depends on the temperature of the air coming from the outer environment.
- the outer environment temperature must be below a certain value in order that sufficient condensation may occur in the condenser and that the laundry can be dried. When the outer environment temperature increases, amount of moisture condensing in the condenser decreases and desired efficiency cannot be obtained in the drying process.
- the aim of the present invention is the realization of a laundry washing and drying machine wherein the condensing efficiency of the air-cooled condenser is improved at high outer environment temperatures.
- the laundry washing and drying machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims comprises at least one temperature sensor detecting the temperature of the cooling air and/or the processing air and a water spraying device connected to the outer water mains through a valve and providing the condenser to be cleaned of fiber and lint, and if the temperature of the cooling air and/or the processing air exceeds the predefined limit values, the water spraying device sprays water onto the condenser.
- the water spraying device is operated in order to cool the condenser even if no fiber and lint accumulates on the condenser.
- the air-cooled condenser is operated with air and water double cold source when the outer environment temperature rises.
- the water spraying device is placed in the vicinity of the condenser so as to aim the cooling channels through which the outer environment air, i.e. the cooling air, passes.
- the water spraying device is placed at the inlet or the outlet part of the air circulation duct through which the processing air passes and by which it is connected to the condenser, and the water spraying device sprays water onto the outer surfaces of the cooling channels in the condenser.
- the fan providing the circulation of the processing air and the water spraying device are operated at intervals in the same time period, thus water sprayed over the condenser for cooling is prevented from being sent onto the laundry together with the processing air.
- the water spraying device is placed at the part of the outer air line that enters into or exits from the condenser, and the water spraying device sends water to the inner surfaces of the cooling channels in the condenser.
- the water spraying device is activated when the temperature of the cooling air and/or the processing air rises and is used for cooling the condenser, thus water cooling support is provided for the air-cooled condenser and the laundry is provided to be dried quickly.
- Figure 1 - is the schematic view of a laundry washing and drying machine.
- Figure 2 - is the schematic view of a laundry washing and drying machine in another embodiment of the present invention.
- the laundry washing and drying machine (1) comprises a drum (2) wherein the laundry is placed, an air circulation duct (3) wherein the circulation of the processing air (PA) providing the drying of the laundry is realized at the drying process after the washing process, a first fan (4) providing the circulation of the processing air (PA), an air-cooled condenser (5) condensing the processing air (PA), an outer air line (6) and a second fan (7) delivering the cooling air (CA) received from the outer environment to the condenser (5) in order to provide the cooling of the condenser (5), a heater (H) placed in the air ventilation duct (3), providing the dehumidified processing air (PA) coming from the condenser (5) to be heated and sent onto the laundry, at least one drying channel (8) passing through the condenser (5), through which passes the processing air (PA) coming from the air ventilation duct (3) by means of the first fan (4), at least one cooling channel (9) passing through the condenser (5), providing to draw heat from the drying channels (8),
- the laundry washing and drying machine (1) of the present invention comprises the control unit (13) that provides water to be sprayed onto the condenser (5) from the water spraying device (12) by opening the valve (11) when the temperature of the cooling air (CA) and/or the processing air (PA) detected by the temperature sensor (10, 110) exceeds the predefined limit temperature values saved in its memory and thus provides the air-cooled condenser (5) to be cooled with water besides air when the temperature of the cooling air (CA) and/or the processing air (PA) rises.
- the control unit (13) that provides water to be sprayed onto the condenser (5) from the water spraying device (12) by opening the valve (11) when the temperature of the cooling air (CA) and/or the processing air (PA) detected by the temperature sensor (10, 110) exceeds the predefined limit temperature values saved in its memory and thus provides the air-cooled condenser (5) to be cooled with water besides air when the temperature of the cooling air (CA) and/or the processing air (PA) rises.
- the water spraying device (12) is positioned near the condenser (5), aiming the walls of the cooling channels (9) so that the cooling channels (9) contact water, and water sprayed onto the condenser (5) touches the cooling channels (9) from inside or outside and decreases the temperature of the cooling air (CA) that passes through the cooling channels (9).
- the difference between the cooling air (CA) and the processing air (PA) is increased and the processing air (PA) is provided to be condensed in a quick manner in the drying channels (8) that transfer heat to the cooling channels (9).
- the processing air (PA) getting humid by passing over the laundry in the drum (2) is sent to the condenser (5) by means of the first fan (4) and the air ventilation duct (3) and passes through the drying channels (8).
- the condenser (5) condenses and dehumidifies the processing air (PA) and the heater (H) heats the processing air (PA).
- the cooling air (CA) passes through the cooling channels (9) in the condenser (5) and the processing air (PA) passes through the drying channels (8).
- the cooling channels (9) decreases the temperature of the humid processing air (PA) passing through the drying channels (8) with which the cooling channels (9) have a heat-transfer relation and condenses the processing air (PA), and the dry processing air (PA) is sent onto the laundry in the drum (2).
- the temperature of the outer environment varies depending on the season and/or the temperature of the room wherein the laundry washing and drying machine (1) operates. When the temperature of the outer environment rises, for examples when it exceeds 30 - 35 ° C, as a matter of course the cooling air (CA) that draws heat from the humid processing air (PA) heats up and cannot provide a sufficient temperature difference for an efficient condensation.
- the control unit (13) opens the valve (11) and activates the water spraying device (12) and thus water is sprayed onto the condenser (5) while the drying process continues.
- the water sprayed onto the condenser (5) contacts the walls of the cooling channels (9) and decreases the temperature thereof, consequently the temperature of the cooling air (CA) passing through the cooling channels (9) decreases, thus, the processing air (PA) is quickly dehumidified by increasing the temperature difference between the processing air (PA) and the cooling air (CA), and the drying effectiveness of the laundry washing and drying machine (1) at high outer environment temperatures is increased.
- the water spraying device (12) is placed at the part of the air ventilation duct (3) that enters into or exists from the condenser (5) and when the temperature of the cooling air (CA) and/or the temperature of the processing air (PA) during the drying process exceeds the recorded limit values, the control unit (13) opens the valve (11) and provides water to be sent from the water spraying device (12) onto the outer surfaces of the cooling channels (9) that are one within the other with the drying channels (8) ( Figure 1). The water sprayed from the water spraying device (12) passes through the drying channels (8) and contacts the outer surfaces of the walls forming the cooling channels (9) and decreases the temperature of the cooling air (CA) that passes through the cooling channels (9).
- the temperature difference between the processing air (PA) and the cooling air (CA) is increased, thereby increasing the condensation effectiveness of the condenser (5).
- the water spraying device (12) sprays water to the drying channels (8) in the condenser (5) after the drying process is completed, and thus provides the removal of the fiber and lint accumulating in the drying channels (8).
- control unit (13) alternately activates the first fan (4) and the water spraying device (12) at intervals, when the temperature of the cooling air (CA) and/or the processing air (PA) rises.
- the valve (11) is closed, and when the valve (11) is opened, that is when the water spraying device (12) is operated, the first fan (4) is deactivated.
- the water sprayed from the water spraying device (12) is prevented from mixing into the processing air (PA) passing through the drying channels (8) and from being sent onto the laundry in the drum (2).
- the water spraying device (12) is placed at the part of the outer air line (6) that enters into or exists from the condenser (5) and when the temperature of the cooling air (CA) and/or the temperature of the processing air (PA) rises during the drying process, the control unit (13) opens the valve (11) and provides water to be sent from the water spraying device (12) onto the inner surfaces of the cooling channels (9) ( Figure 2). Water contacts the inner surfaces of the walls forming the cooling channels (9) and decreases the temperature of the cooling air (CA). Thus, the temperature difference between the processing air (PA) and the cooling air (CA) is increased, thereby increasing the condensation effectiveness of the condenser (5).
- the water spraying device (12) that sprays water onto the condenser (5), thereby providing it to be cleaned of fiber and lint accumulating at the end of the drying process and that is used for the same purpose in the known embodiments, is activated by the control unit (13) when the temperature of the cooling air (CA) and/or the processing air (PA) rises and is used in order to cool the condenser (5).
- the control unit (13) When the temperature of the cooling air (CA) and/or the processing air (PA) rises and is used in order to cool the condenser (5).
- the air-cooled condenser (5) becomes air- and water-cooled, thus providing an efficient and fast drying.
