TR TR TR DESCRIPTION A WASHER WITH INCREASED OPERATIONAL SAFETY This invention relates to a clothes washer dryer with increased operating safety. In washer dryers, the laundry is washed in a washing tub where the detergent loaded into the detergent dispenser and mains water are removed. In the drying process started after the washing process, the air in the boiler is taken into a drying air duct, and the air whose moisture is collected and heated in the drying air duct is sent back to the boiler. One of the problems encountered in the washer dryers known in the art is that the foam formed as a result of the use of detergent water in the washing process reaches the drying air channel from the air inlet. Especially the foam, whose volume increases as a result of intensive detergent use, rises in the drying air duct and overflows through the openings of the drying air duct, and reaches electrical circuits and electronic components, causing security vulnerabilities that may cause corrosion, short circuit formation and even fire. A washer dryer is described in which contact of the foam with electrical elements is prevented. The purpose of this invention is to realize a clothes washer dryer with increased operating safety. The washer dryer defined in the first claim and the claims attached to this claim to reach the purpose of this invention consists of a body, a slot on the body, into which a detergent drawer into which cleaning materials are loaded is placed, and a slot opened to the drum to allow the cleaning materials to be transmitted to the drum. The area consists of a shower unit that feeds water into the housing, a drum in which the laundry is placed and rotated in a drum, a fan that circulates the air and has an air inlet and an air outlet that opens to the drum so that the air taken from the drum is passed through it and sent back to the drum. The drying air channel includes an opening on the drying air channel, a transmission opening located on the housing opening into the housing, and a transmission line extending between the transmission opening and the opening, connecting the drying air channel and the housing. The transmission line provides both air and foam transmission between the drying air channel and the housing. Thus, the transmission line ensures the communication of the boiler with the external environment in a way that prevents air congestion inside the boiler, and also allows the safe evacuation of the foam filled into the drying air duct. In one embodiment of the invention, the air duct has a fan slot on the top of the boiler, into which the fan is placed, and the opening is located on the fan slot. In this way, water filling into the transmission line is prevented by ensuring that the opening remains above the water level in the boiler. In another embodiment of the invention, the flow port is positioned on the shower unit located on the ceiling of the nest. The foam coming from the transmission line pours from the flow opening on the ceiling of the nest to the bottom of the nest under the effect of gravity. Thus, nozzle clogging and foam backflow are prevented. In one embodiment of the invention, the mouth is positioned to face a space between the drawer and the slot when the drawer is in the slot, allowing the foam to be poured into the space. In this way, the foam is prevented from filling into the drawer and it is prevented from mixing with other cleaning materials such as softener and causing incorrect dosing. In another embodiment of the invention, the flow port has an inlet end where the sparkling water coming from the transmission line is taken, an outlet end where the sparkling water is poured into the housing, and a chamber between the inlet end and the outlet end, into which the water coming from the inlet end is filled. Thanks to the chamber, the foam at the outlet facilitates the flow. In another embodiment of the invention, at least one damper is positioned on the flow path of the foam, which includes the opening between the air duct and the housing, the transmission line and the flow port. In this way, the foam is dampened before being poured into the nest, preventing any undesirable accumulation inside the nest. In one embodiment of the invention, the damper is structured in the form of a porous screen. This application is advantageous in that the damper provides effective air permeability. Thanks to this invention, excess foam is prevented from overflowing through the drying air channel by being transferred to the slot. The laundry washer dryer constructed to achieve the purpose of this invention is shown in the attached figures, and from these figures; Figure 1 - Partial schematic view of the clothes washer dryer belonging to an embodiment of the invention. Figure 2 I is a partial view of the clothes washer dryer belonging to another embodiment of the invention, showing the boiler, air duct, housing and transmission line.

Drying air duct Air inlet Air outlet Flow port Transmission line Fan housing Inlet end Outlet end Damper Condenser B:Space Washing machine (1), a body (2), a drum in which washing and drying processes are carried out (3), body (2) A slot (4) with a shower unit (5) that provides water feeding onto the drawer (6) is located on it, into which a drawer (6) suitable for loading detergent is placed, a slot (4) with a shower unit (5) that provides water supply onto the drawer (6), a fan (7) that ensures the circulation of drying air is located, a (3) contains a drying air duct (8) with an air inlet (9) from which air is taken and an air outlet (10) from which air is sent to the boiler (3). The slot (4) is connected to the boiler (3) via an intermediate line (19) and is opened to the outside environment. The drawer (6) suitable for loading detergent is placed in the slot (4). There is a shower unit (5) on the housing (4), which provides water supply to the drawer (6) inside the housing (4). By means of the water fed onto the drawer (6) from the shower unit (5), the detergent in the drawer (6) is swept and flowed into the slot (4) and sent from the slot (4) to the boiler (3) via the intermediate line (19). The laundry in a drum rotated inside the drum (3) is washed in detergent water taken into the drum (3). In the blasting process, air is cycled within the drying air duct (8). The air sucked from the air inlet (9) through the fan (7) is passed through a condenser (20) located on the drying air duct (8), extending almost along the back wall of the boiler, which ensures the condensation of the drying air. The air is dehumidified in the condenser (20). The drying air is passed over a heater (21) located in the duct (8) and blown onto the laundry from the air outlet (10) via the fan (7). The laundry washer dryer (1) that is the subject of the invention consists of an opening (11) located on the drying air duct (8), a flow nozzle (12) located on the slot (4) opening to the slot (4), and one end connected to the flow nozzle (12). ) contains at least one transmission line (13), the other end of which is connected to the opening (11), providing fluidical connection between the housing (4) and the drying air channel (8). The opening (1 1) allows fluid, that is, air and liquid, to enter and exit the drying air channel (8). The flow port (12) is structured as a passage that allows air entry and exit into the housing (4). The transmission line (13) is connected between the flow port (12) and the opening (11). Thus, the drying air channel (8) opening to the boiler (3) and the slot (4) open to the outside atmosphere are connected to each other in a way that allows fluid communication between them via the transmission line (13). If the foam formed during the washing process rises excessively and rises in the drying air channel (8), at least a part of the foam comes out of the opening (1 1) and fills the transmission line (13) and flows into the housing (4) from the flow port (12). In this way, the excess foam is at least partially discharged from the drying air channel (8) to the slot (4). In an embodiment of the invention, the drying air duct (8) has a fan housing (14) into which the fan (7) is placed, and the opening (11) is located on the fan housing (14). The drying air duct (8) has a fan housing (14), located after the condenser (10) in the air flow direction, into which the fan (7) is mounted. The fan housing (14) is located immediately after the condenser (10) extending almost along the rear wall of the boiler, and the opening (11) is positioned on the fan housing (14). Thus, by ensuring that the opening (14) is located at the top of the drying air channel (8), almost at the top, the foam is evacuated to the slot (4) if it rises to a critical level up to the level of the fan (7) in the drying air channel (9). In this way, foam accumulation in the housing (4) is reduced. In another embodiment of the invention, the flow port (12) is located on the shower unit (5). The flow port (12) is positioned on the shower unit (5) located on the ceiling of the slot (4) so that it remains above the drawer (6). In this way, blocking of the flow port (12) is prevented. In this way, the connection of the transmission line (13) to the flow port (12) is facilitated. In another embodiment of the invention, there is a space (B) inside the slot (4), between the drawer (6) and the slot (4), and the flow port (12) opens into the space (B). When the drawer (6) is inside the slot (4), there is a gap (B) between one side of the drawer (6) and the wall of the slot (4). For ease of placement, the gap (B) is preferably located between the rear surface of the drawer (6) and the rear wall of the slot (4). The flow port (12) is positioned on the shower unit (5) facing the bottom of the housing (4) through the gap (B). The foam coming from the transmission line (13) flows from the flow port (12) into the space (B) and pours directly into the slot (4) without filling into the drawer (6). Thus, accumulation on the drawer (6) surfaces is prevented. In another embodiment of the invention, the flow port (12) has an inlet end (15) connected to the transmission line (13), an outlet end (16) opening into the slot (4) and a connection between the inlet end (15) and the outlet end (16). It has one room (17). The foam coming from the inlet end (15) fills into the chamber (17) and flows into the slot (4) from the outlet end (16) located at the bottom of the chamber (17). The chamber (17) facilitates the flow of the foam from the outlet end (16) by widening the flow line between the inlet end (15) and the outlet end (16). In another embodiment of the invention, the transmission line (13) extends at least partially inclined to the vertical. The transmission line (13) extends vertically inclined so that the liquid inside flows towards the flow port (12) under the effect of gravity. Thus, the liquid is prevented from accumulating in the transmission line (13) and blocking the transmission line (13). In this way, air communication between the slot (4) and the drying air duct (8) is prevented from being interrupted. In another embodiment of the invention, the Damper (18) can be placed on the opening (l1), on the transmission line (13) or on the flow port (12). In a preferred version of this application, the damper (18) is located on the opening (1 l). Thus, the amount of liquid transmitted to the slot (4) is reduced. In another preferred version of this application, the damper (18) is located on the flow port (12), especially in the chamber (17). In this way, the foam is dampened just before it is poured into the slot (4), thus reducing residue and foam accumulation in the slot. In another embodiment of the invention, at least one damper (18) is located on at least one of the opening (11), flow port (12) and transmission line (13), which provides damping of the foam. In this way, the foam is dampened before being sent to the housing (4). In another embodiment of the invention, the damper (18) is in the form of a porous screen. The dampener (18) preferably has a large-pore sieve form and ensures the explosion of the foam that hits the pores during the passage of the foamy water. Ease of application is ensured thanks to the simple structure of the damper (18) in the form of a porous sieve. Thanks to this invention, fluid communication is provided between the drying air channel (8) and the housing (4), ensuring safe evacuation of the foam and air in the drying air channel (8). Thus, the operating safety of the washer dryer (1) is increased. TR TR TR
