Definitions

• the present invention relates to a dishwasher comprising a heat pump providing the heating of the wash water.
• a heat pump is used for heating the wash water, by circulating the wash water through a water tank wherein the heat exchanger is disposed, heat is transferred to the wash water from the heat exchanger. If the water in the tank cannot be completely discharged at the end of the washing process, the water remaining inside the tank causes corrosion on the plates of the heat exchanger, preferably produced from copper, thus shortening the lifespan of the heat exchanger. Moreover, the water in the tank becoming green due to its contact with copper contaminates the wash water in the following washing cycles. Moreover, the water collected in the tank causes formation of bacteria and bad odors, leading to problems in terms of hygiene.
• the heat pump and the tank must be placed into a small volume at the base of the dishwasher, preventing structural freedom required for simple solutions.
• a dishwasher comprising a spiral tank that is disposed at the lowermost point of the outlet port.
• a dishwasher comprising a spiral tank with an outlet port that is arranged at the base thereof and that can be opened/closed by a valve.
• the aim of the present invention is the realization of a dishwasher wherein the tank enclosing the heat exchanger is efficiently discharged.
• 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 tank wherein one of the first heat exchanger or the second heat exchanger is placed and that is disposed into the body so that the base thereof is inclined with respect to the floor so as to prevent the accumulation of water therein. With the inclined structure of the tank base, water is prevented from accumulating in the tank and the water inside the tank is enabled to be almost completely discharged.
• a block disposed under the tank provides the inclination of the tank base with respect to the floor.
• the base of the tank is rendered inclined with respect to the floor.
• the block is produced integrated with the tank.
• the upper surface of the block forms the base of the tank.
• the base of the tank is rendered inclined with respect to the floor and the water inside the tank is discharged before accumulating.
• the upper surface of the block is curved. With the curved configuration of the upper surface of the block, the tank receives more water.
• an inlet port provide the entry of water into the tank and an outlet port through which the water inside the tank is discharged are oppositely positioned on the two opposite lateral surfaces of the tank.
• the suction level of which is lower than the level of the outlet port in the vertical direction
• the water in the tank is discharged to the outside.
• the pump is a circulation pump providing the circulation of the wash water.

• Pump The dishwasher (1) comprises a body (2); a heat pump (3) that is disposed inside the body (2), that provides the heating of the water to be used in the washing step and that has a first heat exchanger (4), a second heat exchanger (5) transferring the heat received from the first heat exchanger (4) to the wash water and a compressor (6) fluidly connected to the first heat exchanger (4) and the second heat exchanger (5), realizing the refrigerant cycle, and a tank (7) wherein the first heat exchanger (4) or the second heat exchanger (5) is placed.
• the first heat exchanger (4) or the second heat exchanger (5) By placing the first heat exchanger (4) or the second heat exchanger (5) into a tank (7) containing water, a heat transfer with the water inside the tank (7) is provided. By transferring heat to the water, the water is enabled to be heated, and in the case heat is drawn from the water, the effectiveness of the heat pump (3) is improved. For example, when the wash water is filled into the tank (7) wherein the second heat exchanger (5) is disposed, the wash water is heated or when the mains water is filled into the tank (7) wherein the first heat exchanger (7) is disposed, heat is drawn from the mains water.
• the tank (7) is placed into the body (2) so that the base thereof is inclined with respect to the floor plane.
• the heat pump (3) is preferably located under the tub (not shown in the figures) wherein the washing process is carried out, among water pipes, pumps and water receptacles.
• the dishwasher (1) comprises a block (10) that is disposed under the tank (7) and that enables the base of the tank (7) to be inclined with respect to the floor.
• the block (10) By means of the block (10), the tank (7) is raised from its bottom side, thus the base thereof is enabled to be inclined with respect to the floor and thus the water is prevented from accumulating inside the tank (7).
• the block (10) is produced integrated with the tank (7).
• the upper surface of the block (10) is curved. With the curved configuration of the upper surface of the block (10) integrated with the tank (7), the block (10) is enabled to occupy less space. Thus, while the water is prevented from accumulating inside the tank (7), the tank (7) volume can be used more efficiently.
• the tank (7) has an inlet port (8) that enables the water to enter the tank (7) and an outlet port (9) that enables the water to be discharged out of the tank (7), the inlet port (8) and the outlet port (9) being disposed at the two opposite surfaces of the tank (7).
• the tank (7) is placed into the body (2) so that the outlet port (9) is at a lower level than the inlet port (8).
• a flow is provided inside the tank (7).
• the tank (7) is placed into the body (2) so that the base thereof is inclined with respect to the floor and the water flows from the inlet port (8) towards the outlet port (9).
• the water entering the tank (7) flows towards the outlet port (9) by drawing or giving off heat.
• the water inside the tank (7) is discharged through the outlet port (9) without accumulating on the base thereof.
• the dishwasher (1) comprises a pump (11) that is connected to the outlet port (9), the suction level of which is at a lower level than the outlet port (9).
• the water inside the tank (7) is discharged out of the tank (7) by means of a pump (11), the suction level of which is at a level lower than the outlet port (9).
• the pump (11) is a circulation pump providing the circulation of the wash water.
• the wash water is circulated inside the tank (7) and the discharge of the wash water from the tank (7) is provided by means of the circulation pump (11).
• an additional pump is not required for discharging the water inside the tank and by means of the circulation pump (11) providing the circulation of the wash water inside the tank (7) during the heating of the wash water, the water inside the tank (7) is enabled to be discharged.
• the pump (11) is a discharge pump providing the discharge of the tank (7).
• the water inside the tank (7) is directly discharged without being sent to the sump of the dishwasher (1).
• the waste water containing copper oxides is enabled to be discharged without contacting the dishes.
• the water is prevented from accumulating in the tank (7) situated at the bottom side of the dishwasher (1), the base of the tank (7) is configured so as to be inclined and the tank (7) is enabled to be discharged by means of the pump (11).
