Definitions

• the invention relates to an innovation in vented dryers, which aims to condense the humidity of the air, which has a high temperature and humidity compared to the environment, and to discharge it from the vent after lowering its temperature, and which is also embodied such that it prevents the thermal comfort of the environment from changing.
• the system takes the air it absorbs from the environment and directs it to the outside of the machine environment with an open cycle by dehumidifying of the laundry. According to the suitability of the house and the device, the mentioned humid and hot air is attempted to be evacuated directly to the outside. In cases where it is not possible to evacuate to the outer environment or when the temperature and humidity of the air thrown into the environment are desired to be lowered, the temperature and humidity of the air should be brought to normal levels.
• vented tumble dryers are the dryers with the lowest energy class among other types of textile product dryers.
• the drying air works as an open cycle instead of a closed cycle.
• the hot air which dehumidifies the textile products, passes through the filter and is discharged to the room environment with the help of a vent.
• Vented dryers operating with open cycles on the other hand, sometimes discharge the waste air to the outer environment, and at times regularly release the air of the drying cycle to the environment due to the lack of relevant equipment.
• the humid and hot air taken from the wet textile products is given to the outside until the drying cycle is completed. It is thought that if it cannot be evacuated from the room environment, it will disrupt the comfort of the environment. As a result of the above, a design change in the system is required.
• the invention relates to a tumble dryer.
• An object of the invention is to cool the air exhausted from the textile product dryer and thus, reduce the humidity in the hot air.
• a second pipeline which is fed with mains water, is circulated over the air outlet vent. Thereby, heat transfer takes place from the hot air in the vent to the cold tap water.
• the said invention relates to a textile product dryer.
• the textile product dryer as the subject of the invention has a system to dehumidify the exhausted air. Accordingly, the air comes into contact with a pipe structure in which water is circulated in the outlet region wherein it is cooled down.
• the present invention relates to an innovation in vented dryers in order to eliminate the above-mentioned disadvantages and bring new advantages to the related technical field.
• An object of the invention is to present a vented dryer, which aims to condense the humidity of the air exhausted from the vent and which has a high temperature and humidity compared to the environment and to discharge it by lowering its temperature.
• Another object of the invention is, in case the drying air is given directly to the environment, to put forward a vented dryer that is structured in a way that prevents the thermal comfort of the environment from changing.
• the present invention id a dryer with at least one fan that provides the aspiration of the air from the outer environment and sending of this air to at least one tumbler by passing through at least one heater, in order to cool and dehumidify the hot and humid air that dries the textile products before being discharged into the outer environment.
• its innovation lies in that it comprises a vent that acts as a heat exchanger, provided with at least two nested pipes, at least one internal pipe and at least one external pipe surrounding the said internal pipe.
• it aims to create a vented dryer that allows the hot and humid air that dries the textile products in the dryer to be cooled and dehumidified before being discharged outside of the dryer.
• a characteristic of a possible embodiment of the invention is to provide the said fan element and the motor from which the said tumbler gets its rotational force. Thereby, air is transferred into the dryer, and it provides the necessary power for the dryer to work.
• the characteristic of another possible embodiment of the invention is to provide at least one temperature sensor positioned at the end of the vent, providing communication between the card and the pump mechanism.
• vent is positioned at least partially inclined with respect to the floor in order to carry the condensed water in the same.
• the condensed water is discharged from the vent in a controlled manner.
• the characteristic of another possible embodiment of the invention is that it comprises at least one collecting vessel to which the vent is associated from one side. Thereby, the accumulation of condensed water is ensured.
• vented dryers (10) of the invention is described only for the better understanding of the subject and in the way to create no limiting effect whatsoever.
• Vented dryers (10) in the present technique basically work with the following principle; vented dryers (10) have at least one fan (11) configuration that ensures the continuation of the cycle system.
• Said fan (11) configuration ensures that the air inside the dryer (10) is aspirated and that this air is sent to at least one tumbler (13) by passing through at least one heater (12).
• the circulation of the air inside the dryer (10) is also provided by at least one air inlet opening (14) on the walls of the dryer (10).
• the hot air which dehumidifies the wet textile products in the tumbler (13), passes over at least one cover (16) element and is directed to at least one filter (15), and at least one vent (17) after the said filter (15).
• the circulation air is regularly discharged to the outer environment from the said vent (17).
• Said fan (11) element and said tumbler (13) receive their rotational force by at least one motor (18) located in the dryer (10).
• vent (17) With the innovation in vented dryers (10) with the vent (17) of the invention, some changes have been made, different from the existing dryers (10).
• the temperature drop in the air causes the water vapor in the vent (17) to condense.
• the condensed water drains through the vent (17) designed at an angle of approximately 3° and accumulates in the collecting vessel (50).
• the person using the dryer (10) must replace at least one water collecting vessel (50) after each cycle.
• the air cycle is aspirated from inside the dryer (10) by means of a fan (11 ), such as dryers (10) with vents (17) existing in the state of the art, and sent to the heater (12) in the arrangement, and the air with an increased temperature is sent to the tumbler (13). Then, the hot air, which dehumidifies the textile products, passes through the filter (15) and comes to the vent (17).
• the inner diameter of the vent (17), which acts as a heat exchanger, is approximately 100 mm and its outer diameter is approximately 110 mm.
• the wing structure of the dryer (10), which has a vent (17) system that acts as a heat exchanger, can also change according to the system requirement.
• a vent (17) system is provided in the form of a nested tube. Accordingly, it is seen that while waste hot air passes through at least one internal pipe (171 ), mains water passes through at least one external pipe (172). In this way, the hot air transfers heat to the water in the said external pipe (172) and ensures the cooling of the water.
• the vent (17) system is inclined to discharge the water condensed in the said internal pipe (171 ) as a result of the cooling in the hot air.
• the invention aims to condense the humidity of the air, which has a high temperature and humidity compared to the environment and discharge the same from the vent (17), by lowering its temperature. Thanks to the invention, direct delivery of the drying air to the environment and thus changing the thermal comfort of the environment is prevented. In addition, it is aimed to increase the performance of the dryer (10) with the said invention. Since the energy efficiency of the dryer (10) working with high performance will be high as well, a contribution to the environment and natural resources is aimed.
• thermal comfort is given in ASHRAE Standard 55 - 2004 and ISO 7730.
• the air which changes depending on the decrease in the humidity of the laundry, where the relative humidity is 100%, especially in the first cycles, is given to the environment.
• the air supplied to the environment can reach temperatures of 50°C in the middle of the drying cycle.
• One of the most important shortcomings of the present system is the direct supply of hot air, which aspirates the humidity from the laundry, to the environment.
• the invention not only condenses the humidity of the waste air from the laundry in the vent (17), but also helps to provide the comfort condition by reducing the temperature of the air and thus, meet the present standards.
