Definitions

  • the present invention relates to a dishwasher comprising a water pocket.
  • the dishes are placed onto the racks provided in the washing tub.
  • the cleaning process is performed by delivering water onto the racks by means of the spraying member.
  • the water is heated before being delivered onto the dishes.
  • a more effective cleaning is performed.
  • the water taken from the mains is collected in a water pocket.
  • the water pocket is disposed between the body and the washing tub. Heat exchange occurs between the water pocket and the washing tub. Thus, the water in the water pocket is heated a little. Energy is saved by heating the water before taking into the washing tub.
  • there are dishwashers wherein the dirty and hot water leaving the washing tub is used to heat the water in the water pocket by means of a line provided on the water pocket.
  • the hot and dirty water used in the washing process flows through a line provided on the water pocket such that heat exchange occurs between the cold water in the water pocket and the hot and dirty water.
  • heat recovery is provided.
  • the total cycle duration of the dishwasher increases. Therefore, the heat recovery process must be performed as quickly as possible. In order to increase the speed, the performance of the heat recovery process must be increased as well.
  • the aim of the present invention is the realization of a dishwasher wherein saving in time is provided.
  • 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 sump which is disposed on the base of the washing tub; at least one spraying member which is provided in the washing tub and which provides the delivery of the water onto the kitchen items; a circulation pump which enables the water to be transferred from the sump to the spraying member; a heater which is disposed on the circulation pump; a multiport valve which provides the delivery of the water to the spraying member; a water pocket which is disposed between the washing tub and the body; and a heat exchanger which is connected to the sump at one end and to the multiport valve at the other end, and which extends into the water pocket.
  • the water in the sump is heated by means of the circulation pump and delivered to the spraying members.
  • the spraying member which receives the water is determined by means of the multiport valve.
  • the hot water used in the washing process is directed to the heat exchanger by means of the multiport valve.
  • the hot water flowing through the heat exchanger returns to the sump.
  • the cold water taken into the water pocket is heated by means of the heat exchanger.
  • the dishwasher of the present invention comprises a water movement means which enables the water collected in the water pocket to move and thus contact the heat exchanger more.
  • the water movement means By means of the water movement means, the static water in the water pocket becomes dynamic. Thus, a larger amount of water contacts the heat exchanger in the unit time.
  • the dishwasher comprises a discharge pump which is connected to the sump; a first valve which is disposed between the discharge pump and the sump; a second valve which is connected to the discharge pump; and a delivery line which enables the water leaving the discharge pump to be delivered to the water pocket and enables the water in the water pocket to be delivered back to the discharge pump via the first valve and from there to the second valve.
  • the delivery line By means of the delivery line, the water in the water pocket is kept moving without using an additional component.
  • the dishwasher comprises at least one ultrasonic vibration member disposed on the water pocket.
  • the ultrasonic vibration member By means of the ultrasonic vibration member, the water in the water pocket is kept moving thanks to vibrations.
  • the dishwasher comprises the ultrasonic vibration member disposed along a surface of the water pocket. As the size of the ultrasonic vibration member increases, the water movement rate also increases. Thus, the water is heated more quickly.
  • the dishwasher comprises an air compressor which is disposed in the vicinity of the water pocket and an air delivery line which is connected to the air compressor.
  • air delivery line connected to the air compressor, air bubbles are generated in the water pocket such that the water in the water pocket is kept moving.
  • the dishwasher comprises a mixer which is disposed longitudinally in the water pocket and a motor which controls the movement of the mixer.
  • the mixer By means of the mixer, the water in the water pocket moves continuously and a homogeneous structure is obtained.
  • a dishwasher comprising a water movement means which moves the mains water collected in the water pocket such that the water is heated more quickly.
  • 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 sump (4) which is disposed on the base of the washing tub (3) and wherein the water coming from the washing tub (3) is collected; at least one spraying member (5) which is disposed in the washing tub (3) and which sprays the water coming from the sump (4) onto the kitchen items; a circulation pump (6) which enables the water to be transferred from the sump (4) to the spraying member (5); a heater (7) which is disposed on the circulation pump (6); a multiport valve (8) which is disposed between the circulation pump (6) and the spraying member (5) and which directs the water to the spraying member (5); a water pocket (9) which is disposed between the washing tub (3) and the body (2) and wherein water is collected to be used in the washing process; and a heat exchanger (10) which is connected to the sump (4) at one end and to the multiport valve (8) at the other end and which extends into the water pocket (9
  • the water in the sump (4) is heated by means of the circulation pump (6) and delivered to the spraying members (5).
  • the spraying member (5) which receives the water is determined by means of the multiport valve (8).
  • the hot water used in the washing process is directed to the heat exchanger (10) by means of the multiport valve (8).
  • the hot water flowing through the heat exchanger (10) returns to the sump (4).
  • the cold water taken into the water pocket (9) is heated by means of the heat exchanger (10).
  • the dishwasher (1) of the present invention comprises a water movement means (11) which enables the water collected in the water pocket (9) to flow and thus contact the heat exchanger (10) more in the unit time.
  • the water movement means (11) By means of the water movement means (11), the mains water collected in the water pocket (9) is kept moving.
  • the amount of water which contacts the heat exchanger (10) in the unit time increases, which enables the water in the water pocket (9) to be heated more quickly.
  • the dishwasher (1) comprises the water movement means (1) composed of a discharge pump (12) which is connected to the sump (4) and which discharges the water in the sump (4), a first valve (13) which is disposed between the discharge pump (12) and the sump (4), a second valve (14) which is connected to the discharge pump (12) and a delivery line (15) which enables the water drawn from the second valve (14) to be delivered to the water pocket (9) and enables the water in the water pocket (9) to be delivered back to the discharge pump (12) via the first valve (13).
