Description

STEAM SPRAYER
The present invention relates to a steam sprayer enabling removing odors and reducing wrinkles of the laundry items in dryers or washer-dryers.
Dryers may have odor removal and wrinkle reduction functions as additional features. To that end, water in hot steam or spray form should be sent on the laundry items. A certain amount of water required during such a program needs to be stored anywhere in the machine. This water can thus be used in proper moments of such a program. Said water to be utilized should be filled into a tank by the user , which requires performing specific operation steps. This causes challenges for the user, leading to such programs not being used frequently. In addition, in using steam spray filled with water by the user, utilizing components such as additional piping and steam container increases the cost of such a product.
State of the art document no. EP2775027A1 discloses receiving water by a pump from a tank and sending water on laundry through a nozzle. In said patent document, water is drawn not from the chamber where a condenser pump is disposed, but by a spray steam system from an upper tank to which the condenser pump pumps the condensing water,
In the state of the art document no. WO2011128241A1, condensed water is collected in a container and is sent to the upper portion of the machine by a pump. Water coming here through a line fills through an inlet into a tank disposed above and a part thereof concurrently accumulates in the container by-passing said tank. Water collected in the container is converted to steam by a steam generator when required or at appropriate times, and is sent on the laundry items.
The aim of the present invention is to realize a steam sprayer enabling removing odors and reducing wrinkles of the laundry items in dryers or washer-dryers without requiring an additional water chamber.
Another aim of the present invention is to realize a steam sprayer enabling utilizing waste water and having a low production cost by enabling using currently available parts and components of dryers or washer-dryers.
The steam sprayer realized to achieve the aims of the present invention is illustrated in the accompanying drawings, wherein:

A waste water chamber (5) connected to the condensation pump (4) is provided, in which waste water of the condensation pump (4) is collected. The waste water chamber (5) is disposed on the chassis (2). A spray pump (6) is connected to the waste water chamber (5) and the spray pump (6) conveys the water in the waste water chamber (5) to the drum (3) by means of a spray hose (7) connected to the spray pump (6). A control unit is provided, adapted to control the spray pump (6). A nozzle (8) is connected to the end of the spray hose (7) and the nozzle (8) sends water into the drum (3) by dispersing it as particles. The nozzle (8) also sends water with steam into the drum (3) as high temperature water is collected in the waste water chamber (5). The control unit activates the spray pump (6) according to user instructions, and following activation of the spray pump (6), the nozzle (8) sends water as steam or as particles into the drum (3). Odor removal or wrinkle reduction of the laundry items in the drum (3) is thus performed. The steam sprayer (1) of the invention enables utilizing waste water as well as realizing a system with low production cost by enabling using currently available parts and components of dryers or washer-dryers.
In a preferred embodiment of the invention, a system with evaporator is used to dehumidify the laundry items in the drum (3) in machines with heat pump, and water is collected in the waste water chamber (5) by means of the condensation pump (4). At least one spray water chamber (9) is provided, positioned besides the waste water chamber (5) to drain the water in the waste water chamber (5) therein. Once the condensation water reaches a given level in the waste water chamber (5), it fills into the spray water chamber (9). The spray pump (6) is connected to the spray water chamber (9) and the spray pump (6) conveys the water in the spray water chamber (9) to the drum (3) by means of a spray hose (7) connected to the spray pump (6). A nozzle (8) is connected to the end of the spray hose (7) and the nozzle (8) sends water steam into the drum (3). Since the provided spray water chamber (9) is not connected to the condensation pump (4), the water pumped by the condensation pump (4) to the upper tank departs from the water collected in the spray water chamber (9), enabling the spray water chamber (9) to remain continuously full. Whereby a user does not need to perform a filling operation during odor removal and wrinkle reduction operations of the laundry items in the drum (3).
In a preferred embodiment of the invention, a dryer or washer-dryer comprising the steam sprayer (1) comprises a chassis (2) and a drum (3) is placed in the chassis (2). In machines with heater, a system with condenser is used to dehumidify the laundry items in the drum (3) and a condenser pump is provided on the chassis (2). A waste water chamber (5) is provided, connected to the condenser pump, in which the waste water of the condenser pump is collected. The waste water chamber (5) is disposed on the chassis (2). A spray pump (6) is connected to the waste water chamber (5) and the spray pump (6) conveys the water in the waste water chamber (5) to the drum (3) by means of a spray hose (7) connected to the spray pump (6). A control unit is provided, adapted to control the spray pump (6). A nozzle (8) is connected to the end of the spray hose (7) and the nozzle (8) sends water into the drum (3) by dispersing it in particles. The nozzle (8) also sends steam water into the drum (3) as high temperature water is collected in the waste water chamber (5). The control unit activates the spray pump (6) according to user instructions, and following activation of the spray pump (6), the nozzle (8) sends water as steam or as particles into the drum (3). Odor removal or wrinkle reduction of the laundry items in the drum (3) is thus performed. The steam sprayer (1) of the invention enables utilizing waste water as well as realizing a system with low production cost by enabling using currently available parts and components of dryers or washer-dryers.
In a preferred embodiment of the invention, a system with condenser is used to dehumidify the laundry items in the drum (3) in machines with heater, and water is collected in the waste water chamber (5) by means of the condenser pump. At least one spray water chamber (9) is provided, positioned besides the waste water chamber (5) to drain the water in the waste water chamber (5) therein. Once the condensation water reaches a given level in the waste water chamber (5), it fills into the spray water chamber (9). The spray pump (6) is connected to the spray water chamber (9) and the spray pump (6) conveys the water in the spray water chamber (9) to the drum (3) by means of a spray hose (7) connected to the spray pump (6). A nozzle (8) is connected to the end of the spray hose (7) and the nozzle (8) sends water steam into the drum (3). Since the provided spray water chamber (9) is not connected to the condensation pump (4), the water pumped by the condensation pump (4) to the upper tank departs from the water collected in the spray water chamber (9), enabling the spray water chamber (9) to remain continuously full. Whereby a user does not need to perform a filling operation during odor removal and wrinkle reduction operations of the laundry items in the drum (3).
