Description
Technical Field
The present invention relates to a dishwasher including a UV (ultraviolet) light source.
Background
In a dishwasher, dirty kitchen utensils are placed in a washing tub to be washed. The kitchen appliance is cleaned by means of water sprayed through the spray arm. In addition to washing with water, the use of UV (ultraviolet) light sources in dishwashers, which enable the ultraviolet light to be dissipated inside the washing tub, is also a known application. The washed dishes are sterilized by means of the UV light source. Sterilization of dishes is crucial in areas such as restaurants or hospitals: kitchen appliances are commonly used and hygiene is critical. Accordingly, a dishwasher capable of sterilization is preferable. Generally, the UV light source is placed in the vicinity of the spray arm. This enables the UV light source to dissipate light from an equal distance from the kitchen utensils placed in the washing tub. The UV light source may be controlled by means of a control unit of the dishwasher and may be activated according to the preferences of the user. An electrical connection is established from the control unit to the UV light source to power the UV light source. The electrical connection is usually realized by means of a cable line. However, the presence of a cable line in the washing tub may be dangerous due to the continuous water circulation in the washing tub. This defines the area in which the UV light source can be positioned, thereby reducing the efficiency of sterilization.

Detailed Description
The dishwasher (1) comprises: a main body (2); a washing tub (3) provided on the main body (2), in which a washing process is performed in the washing tub (3); a lower spray arm (4) and/or an upper spray arm (5) provided in the washing tub (3), the lower spray arm (4) and/or the upper spray arm (5) enabling the delivery of water to the kitchenware placed in the washing tub (3); and a UV (ultraviolet) light source (6) arranged in the washing tub (3), the UV light source (6) terminating microorganisms on the kitchenware placed in the washing tub by emitting ultraviolet radiation, the UV light source (6) being in an active position when radiating UV light and in a passive position when not radiating UV light. The washed kitchen utensils are sterilized by means of a UV light source (6).
The dishwasher (1) of the invention comprises an energy source (7) connected to the UV light source (6), the energy source (7) providing energy to the UV light source (6) by generating energy by means of a fluid in the washing tub (3) and thereby enabling the UV light source (6) to be switched to an active position. The UV light source (6) does not need to be powered by the cable by means of an energy source (7). This enables the UV light source (6) to be positioned in a variety of areas.
In an embodiment of the invention, the dishwasher (1) comprises an energy source (7), the energy source (7) being a hydro-generator (9), the hydro-generator (9) having: a turbine (7) rotated by means of the fluid in the washing tub (3); and an electric generator (8) connected to the turbine (7). The fluid used in the washing cycle enables the turbine (7) to rotate by impacting the blades of the turbine (7). The turbine (7) generates mechanical energy by rotating. The generated mechanical energy is transmitted to the generator (8) and converted into electrical energy by the generator (8). This enables the UV light source (6) to be energized.
In an embodiment of the invention, the dishwasher (1) comprises a UV light source (6), the UV light source (6) being powered by means of conveying water from the spray arm to a hydro generator (9) by being arranged in the vicinity of the lower spray arm (4) and/or the upper spray arm (5). The fluid flow contacting the turbine (7) is increased by means of a hydro-generator (9) arranged in the vicinity of the spray arms (4, 5). This increases the amount of energy generated for switching the UV light source (6) to an active position.
In an embodiment of the invention, the dishwasher (1) comprises a fan (10), the fan (10) being arranged in the vicinity of the turbine (7) and thereby enabling the turbine (7) to rotate and the UV light source (6) to be switched to an active position. The fan (10) enables the turbine (7) to rotate and the hydro-generator (9) to generate electricity. This enables switching of the UV light source (6) to an active position. In addition, the use of the fan (10) enhances drying performance.
In an embodiment of the invention, a dishwasher (1) comprises: a variable speed motor (11) provided on the main body (2), the variable speed motor (11) enabling control of the water pressure delivered to the washing tub (3); and a control card (12) which enables the hydroelectric generator (9) to generate energy when the speed of rotation of the variable speed motor (11) exceeds a threshold value predetermined by the producer. Since the water flow intensity increases when the rotational speed of the motor (11) exceeds a given threshold value, the washing tub (3) is cleaned from residues, such as detergent and dirt particles. The dishes are made cleaner by means of a UV light source (6) radiating for a given period of time and at a predetermined time.
In an embodiment of the invention, a dishwasher (1) comprises: a control unit (13) provided on the main body (2), the control unit (13) enabling control of an operation process such as washing or drying; and a switch (14) arranged between the hydro-generator (9) and the UV light source (6) and powered by the control unit (13). The energy flow from the hydro generator (9) to the UV light source (6) is controlled by means of a switch (14) arranged between the hydro generator (9) and the UV light source (6). Thereby, the UV light source (6) is limited from switching to the active position each time the hydro-generator (9) is activated. The switch (14) is controlled by a control unit (13). Thus, the UV light source (6) is switched to the active position according to the user's desire.
In an embodiment of the invention, the control unit (13) enables the switch (14) to be triggered in the rinsing step and the UV light source (6) to be switched to the active position. The control unit (13) determines that the dishwasher (1) is in a washing step, such that the switch (14) can be triggered and thereby the UV light source (6) can be energized by the hydroelectric generator (9). The dishes are sterilized by means of a UV light source (6) which is switched to an active position in the rinsing step.
In an embodiment of the invention, the control unit (13) enables switching the UV light source (6) to the passive position when presence of detergent or dirt particles in the washing tub (3) is detected. The control unit (13) checks whether dirt particles or detergent are present in the washing tub (3). When the presence of detergent or dirt particles is detected, the UV light source (6) is enabled to switch to a passive position. This prevents subjecting the detergent or soil particles to ultraviolet light, thereby enhancing washing performance.
In an embodiment of the invention, the dishwasher (1) comprises a hydro generator (9), the hydro generator (9) saving energy when the UV light source (6) is in the active position. A hydro-generator (9) generates the energy required to switch the UV light source (6) to the active position. This enables energy saving.
The invention enables a dishwasher (1) to be achieved, the dishwasher (1) comprising a UV light source (6), the UV light source (6) being switched to an active position by means of energy generated by passing a fluid used in a washing cycle through a hydroelectric generator (9). Thereby, no cable connection is required between the control unit (13) and the UV light source (6) for switching the UV light source (6) to the active position, thereby improving product safety. The UV light source (6) is energetically independent of the control unit (13), which increases the number of areas where the UV light source (6) can be positioned on the body (2). Thus, the UV light source (6) can be used more efficiently, thereby enhancing cleaning performance.
