Description

[0001] A TUMBLE DRYER WITH WATER TANK

[0002] TECHNICAL FIELD

[0003] The invention relates to a tumble dryer in which microplastic particles can be separated from wastewater.

[0004] BACKGROUND

[0005] Today, measures are taken against the damage caused by micro-sized plastics released into nature. One of the important sources of microplastic emissions is laundry. When laundry is washed or dried, they release micro-sized fibers into the ecosystem. In a recent study, 6,000,000 microfibers are observed to be released from 6 kg of laundry (DeFalco et aL, 2018). In washing and tumble dryers, microparticles are torn from the laundry due to heat and abrasion and thrown out with mains water. Microplastics that are released into the environment as waste enter the food chain or harm living things by inhalation.

[0006] The water withdrawn from the mains in the washing machines will take the detergent from the detergent box and will begin to fill the bowl where the laundry will be. After reaching a certain level, the machine stops taking water and the laundry starts washing. After the washing process is finished, the rinsing phase begins. The dirty water is discharged with the help of the pump motor and clean water is filled to a certain level in the boiler for the rinsing process. With the effect of the drain pump and the high boiler speed, the laundry completes the rinsing process. Washing machines consume an average of 50 liters of water. Tumble dryers, on the other hand, have a drum cycle and a heated air process that provides regular dehumidification. Dehumidified air condenses in the condenser area and releases moisture into the condenser channel. Regularly accumulated water is discharged by the customer or directly to the network. This amount of water is about 5 liters. As a result of this process, microplastics that break off from the laundry are sent to nature.

[0007] In the white goods sector, systems and designs that can be integrated outside the machine and inside the machine have been developed to prevent the release of microplastics from washing machines. Drying is also performed in tumble dryers by removing the moisture in the laundry. There are three different types of dryers on the market: heat pump, condenser, and chimney. The chimney-type dryers differ from other models by removing the air taken from the laundry with the help of a chimney. In condenser and heat pump models, the hot air leaving the drum leaves its moisture in the chamber inside the machine with the help of a condenser. The water collected in the tank is discharged at the end of the drying process. In the laundry drying process, microplastics are released as in washing machines, and with the return of wastewater to nature, the environment is polluted by microplastics.

[0008] As a result, all the above-mentioned problems have made it imperative to innovate in the relevant technical field.

[0009] BRIEF DESCRIPTION OF THE INVENTION

[0010] The present invention relates to a tumble dryer for eliminating the above-mentioned disadvantages and bringing new advantages to the relevant technical field.

[0011] The object of the invention is to provide a tumble dryer in which microplastic particles can be easily collected.

[0012] Another object of the invention is to provide a tumble dryer where microplastic particles can be collected at low costs.

[0013] The present invention relates to a tumble dryer having a body, a drum provided in said body, and a cover that allows access to the drum, sending hot air into the drum to dry the laundry, and a water tank that is removably positioned on the cover where the water is stored as a result of condensation as a result of the drying process in order to realize all the objects that will emerge from the abovementioned and the following detailed description. Accordingly, it includes a microplastic gripper provided at a water inlet port of the water tank. Thus, microplastic particles are collected during the transfer of the wastewater to the water tank for discharge.

[0014] The microplastic gripper is removably connected to the water tank in a possible embodiment of the invention. Thus, after the water tank is separated from the cover or before it is separated, the microplastic gripper can be discharged by removing it from its place and the microplastics are prevented from being mixed into the wastewater.

[0019] DETAILED DESCRIPTION OF THE INVENTION

[0020] In this detailed description, the tumble dryer (10) of the invention is explained only by means of examples that will not have any limiting effect for a better understanding of the subject matter.

[0021] The tumble dryer (10) of the invention has a body (20). There is a drum (22) provided in the body (20). The drum (22) rotates with the drive it receives from a motor (not shown). It is possible to access the drum (22) by means of a cover (30) hinged on the body (20).

[0022] There is also a heater (23) to provide heating of the air inside the body (20) and a fan (21 ) to ensure that the heated air is directed into the drum (22). During the operation of the tumble dryer (10), the hot air dehumidifies the laundry. It is then condensed and collected in a tank (24). When the amount of water in the tank (24) exceeds a predetermined level, the water is sent to a water tank (40) through a pump (not shown in the figure).

[0023] In the tumble dryer (10) of the invention, the water tank (40) is located on the cover (30). On the other hand, the water tank (40) is removably connected to the face of the cover (30) facing the drum (22). Therefore, when water accumulates in the water tank (40), the user can easily see through the cover (30) and can empty the water tank (40) by removing it. The water tank (40) is made of a transparent material in a possible embodiment of the invention. There is also at least one handle (42) provided to allow easy holding of the water tank (40).

[0024] There is a water inlet port (41 ) on the water tank (40) to allow water to enter. The water sent from the tank (24) through the pump is poured into the water inlet port (41 ). There is a microplastic gripper (50) positioned in the water inlet port (41 ). Therefore, the water poured into the water inlet port (41 ) first enters the microplastic gripper (50). Said microplastic gripper (50) allows the microplastic particles in the water to be retained. The microplastic gripper (50) is made of plastic material in a possible embodiment of the invention. The filtering element (51 ) used by adhering to the gaps on the microplastic gripper (50) is a transparent color. The fabric of the filtering element (51 ) of this microplastic gripper (50) can be made of different materials. The permeability of the fabric allows the flow of water while filtering microplastics. This is all about the number of pores and pore sizes of the fabric.

[0025] Due to the fact that the water tank (40) is positioned on the cover (30), the user can see the amount of waste in the microplastic gripper (50) when it is separated from the cover (30) to empty the water tank or when the water tank (40) is on the cover (30). Therefore, it can be intervened when necessary to drain the microplastic gripper (50), which is a kind of filter.

[0026] The microplastic gripper (50) is removably connected to the water tank (40) in a possible embodiment of the invention. Therefore, when the user separates the water tank (40) from the cover (30) to empty it, he / she can easily empty the microplastic gripper (50) by removing it from the water tank (40). In the alternative structure, it is possible to clean the microplastic gripper (50) without leaving the water tank (40).

[0027] There are 2 different cycles in the tumble dryer (10) of the invention, one open and the other closed. In the closed loop; the air inside the body (20) is first heated by passing through the heater (23) with the help of the fan (21) and then sent to the drum (22) where the laundry is located. The fan (21) receives its force from the motor that also moves the drum (22). The heated air takes up some of the moisture on the laundry as it passes through the drum (22). Hot and humid air is passed through a filter to hold the pieces of fiber that break off from the laundry and the air is directed into the condenser through the diverter channel. In the second cycle, the ambient air taken from the outside of the body (20) is directed to the condenser fins. Hot and humid air from the closed loop and ambient air taken from outside are crossflowed through the condenser. Heat transfer is performed through fins integrated with condenser channels. The temperature of the closed loop air drops and some of the moisture condenses in the condenser channels to become liquid. The condensing water accumulates up to a predetermined amount in the tank (24) in the body (20). The pump starts when the fluid level exceeds the predetermined level. With the help of a pump, water is transported to the water tank (40) provided on the cover (30). The water passing through the microplastic gripper placed in the water inlet port (41) of the water tank (40) begins to fill the water tank (40). Thanks to the visibility of the water tank (40) and the microplastic gripper (50) on the cover (30), the user can empty the water tank (40) and thus the microplastic gripper (50) by separating from the cover (30) when he wants to empty any of them. The microplastics can be easily collected in the tumble dryer (10) of the invention and the need can be easily detected by the user without the need for an additional sensor. On the other hand, since the microplastic gripper (50) is at the water inlet port (41) of the water tank (40) and in the area where the water is poured by gravity, no additional power is required to hold the particles.

[0028] The protection scope of the invention is specified in the appended claims and cannot be strictly limited to those explained in this detailed description for illustrative purposes. It is evident that a person skilled in the art may exhibit similar embodiments in light of the foregoing without departing from the main theme of the invention.
