In the heat pump dishwashers, the water heating process is realized by means of the heat pump system. The washing water accumulated under the tub is delivered to the water heating receptacle which contains the condenser by means of the circulation pump. The water heating up in the water heating receptacle is directed to the spray arms by means of the multiport valve. This cycle continues until the temperature of the washing water reaches the desired value. The evaporator in the heat pump system draws heat from the environment while the compressor delivers heat to the condenser, and the condenser transfers heat to the washing water. At least one fan directs the ambient air towards the evaporator such that the evaporator draws heat. The ambient air passing over the evaporator leaves its heat on the surfaces thereof and the air leaving the evaporator is discharged to the kitchen environment. The water vapor in the ambient air getting in contact with the evaporator condenses and the resulting water droplets are accumulated in the condensation receptacle under the evaporator. The volume of the condensation receptacle is limited, and if not emptied in time the water in the condensation receptacle overflows and disperses on the floor. The humidity of the ambient air used decreases depending on the operation of the heat pump system, the air in the environment wherein the dishwasher is installed gets dry, and the dry air disturbs the user.
  • The Patent No. EP2682037 (B1) relates to a heat pump dishwasher wherein the water condensed on the evaporator surfaces due to the humidity of the ambient air is accumulated in a condensation receptacle.
  • The Patent Application No. EP3166466 (A1) relates to the method for transferring the water condensing on the evaporator surface to the washing cycle in a heat pump dishwasher.
  • The Patent Application No. CN105476584 (A) discloses the placement of the evaporator, the compressor and the fan into a channel under the body of the dishwasher.
  • The aim of the present invention is the realization of a heat pump dishwasher which improves the air conditions of the environment wherein the same is installed.
  • The dishwasher realized in order to attain the aim of the present invention is of heat pump type, and comprises a compressor, a condenser, an evaporator, an expansion element and a condensation receptacle wherein the water condensing on the evaporator is accumulated, which together perform the refrigerant cycle. The washing water is heated by the condenser. The dishwasher of the present invention comprises an air duct having an inlet port which collects the air leaving the evaporator during the washing process and an outlet port which opens to the kitchen environment. The water taken from the evaporator condensation receptacle is delivered into the air duct by means of a water supply line. The air passing through the air duct evaporates the water taken from the condensation receptacle and humid air is delivered to the kitchen environment through the outlet port. Thus, the air in the environment wherein the dishwasher operates is prevented from getting dry and disturbing the user.
