Definitions

  • the present invention relates to a dishwasher comprising a heater.
  • the washing process is composed of certain steps.
  • the prewashing step the dirt on the dishes is removed.
  • the temperature of the water is increased, and the main washing step is performed wherein the cleaning is realized with hot water and detergent.
  • the main washing step the oil residues and dirt on the dishes are removed.
  • the rinsing steps after the main washing step the detergent residues and dirt residues are removed from the surfaces of the dishes.
  • the drying step is performed. By means of the drying step, the water droplets on the dishes are dried. Thus, the formation of stains on the dishes is prevented and the dishes are unloaded from the machine in a dry state. In order to ensure an efficient drying step, the dishes are heated before the drying step.
  • the heating process is realized by heating the water.
  • the temperature of the water is increased to high levels and the washing performance is increased.
  • an additional heater is not used to heat the air therein.
  • keeping the washing water circulating through the washing tub to heat the dishes at high temperatures increases the amount of energy consumed.
  • the temperature of the water is not high enough, the drying performance decreases.
  • the aim of the present invention is the realization of a dishwasher with improved drying performance.
  • the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a washing tub which is disposed in the body; a door which is provided on the body; a sump wherein the water leaving the washing tub is collected; at least one rack which is disposed in the washing tub and wherein the kitchen items are loaded; and at least one spraying member which sprays water onto the rack.
  • the water sprayed onto the rack by means of the spraying member leaves the washing tub to be collected in the sump.
  • the water is cleansed of dirt in the sump.
  • the dishwasher of the present invention comprises a heater which heats the water collected in the sump and a control unit which provides the delivery of the water heated in the sump onto the rack for a certain time.
  • the water collected in the sump is heated by means of the heater and reused in the washing tub.
  • the water in the sump reaching a temperature value predetermined by the producer is delivered onto the kitchen items for a time predetermined by the producer. Thus, the kitchen items are heated.
  • the dishwasher comprises the control unit which keeps the door open for a time predetermined by the producer after the dishes are heated by means of the water heated in the sump. By opening the door, a circulation between the air in the washing tub and the ambient air is generated, and thus the drying performance is increased.
  • the dishwasher comprises the heater which heats the water collected in the sump to a temperature between 45°C and 100°C.
  • the control unit controls the heater to ensure that the heating is performed within a certain range. By spraying the water at a temperature between 45°C and 100°C onto the dishes for a certain time, the surface temperature of the dishes is increased.
  • the dishwasher comprises the spraying member which sprays the water heated in the sump onto the rack for a time between 1 second and 5 minutes, and the control unit which controls the spraying member.
  • the control unit which controls the spraying member.
  • the dishwasher comprises at least one valve which controls the delivery of the water into the washing tub, and the control unit which controls the valve.
  • the control unit controls the valve.
  • the valves are closed so as to prevent the delivery of the water into the washing tub.
  • the temperature of the water is increased while the same is static.
  • the dishwasher comprises a pump which controls the pressure of the water delivered through the spraying member, and the control unit which controls the rotational speed of the pump.
  • the control unit controls the rotational speed of the pump.
  • a dishwasher comprising a heater which heats the water in the sump while it is static, and a control unit which controls the delivery of the heated water onto the rack.
  • the dishwasher (1) comprises a body (2); a washing tub (3) which is disposed in the body (2) and wherein the washing process is performed; a door (11) which interrupts the contact between the washing tub (3) and the outer environment; a sump (4) which is disposed at the base of the washing tub (3) and wherein the water is collected; at least one rack (5) which is disposed in the washing tub (3) and wherein the kitchen items are loaded; and at least one spraying member (6) which sprays water onto the rack (5).
  • the washing process is performed with the spraying members (6) in the washing tub (3) spraying water onto the kitchen items.
  • the water leaving the washing tub (3) is collected in the sump (4).
  • the dishwasher (1) of the present invention comprises a heater (7) which is provided on the sump (4), and a control unit (8) which enables the water collected in the sump (4) before the drying step to be heated by the heater (7) to a value predetermined by the producer and to be delivered onto the dishes for a time predetermined by the producer.
  • the heater (7) provided on the sump (4) the water collected in the sump (4) is heated.
  • the control unit (8) the heated water is delivered onto the kitchen items loaded into the rack (5) for a time predetermined by the producer before the drying step.
  • the surfaces of the kitchen items are heated, and the drying performance is increased.
  • the dishwasher (1) comprises the control unit (8) which enables the door (11) to be kept open for a time predetermined by the producer after the drying step starts. After the dishes are heated by means of the water heated by the heater, the drying step starts, and the door (11) is enabled to be kept open for a predetermined time during the drying step. By opening the door (11), the air in the washing tub (3) and the ambient air mix with each other. Thereby, the drying performance is increased.
  • the door (11) is kept open for a time between 1 seconds and 10 minutes, preferably for 1 minute.
  • the dishwasher (1) comprises the heater (7) which heats the water collected in the sump (4) to a temperature between 45°C and 100°C, and the control unit (8) which controls the heater (7).
  • the control unit (8) which controls the heater (7).
  • the dishwasher (1) comprises the spraying member (6) which sprays the water heated in the sump (4) onto the rack (5) for a time between 1 second and 5 minutes, and the control unit (8) which controls the time.
  • the control unit (8) which controls the time.
  • the dishwasher (1) comprises at least one valve (9) which controls the delivery of the water from the spraying member (6) into the washing tub (3), and the control unit (8) which keeps the valves (9) closed while the water is being collected in the sump (4).
  • the control unit (8) which keeps the valves (9) closed while the water is being collected in the sump (4).
  • the valves (9) By closing the valves (9) while the water is being collected in the sump (4), the water is prevented from being delivered by the spraying member (6).
  • the static water collected in the sump (4) is enabled to reach the desired temperature.
  • energy saving is provided.
  • the dishwasher (1) comprises at least one pump (10) which controls the pressure of the water delivered from the spraying member (6) into the washing tub (3), and the control unit (8) which decreases the rotational speed of the pump (10) while the water is being collected in the sump (4).
  • the control unit (8) which decreases the rotational speed of the pump (10) while the water is being collected in the sump (4).
  • a dishwasher (1) comprising a heater (7) which heats the water used in the washing step after it is collected in the sump (4), and a control unit (8) which provides the delivery of the heated water onto the dishes on the rack (5).
