Dishwasher and associated control method

Abstract

A dishwasher having a sequencing controller in which a washing program to control a wash cycle for cleaning dishes is stored; a washing chamber to receive the dishes during the wash cycle; a sorption drying device including a sorption system with a reversibly dehydratable material; and a water feed device having a hot water feed to receive hot water from an external hot water supply and a cold water feed to receive cold water from an external cold water supply. The washing program has a program step to wash the dishes using the hot water from the hot water supply and a program step to wash the dishes using the cold water from the cold water supply.

1 . A dishwasher, comprising:
 a sequencing controller in which at least one washing program to control at least one wash cycle for cleaning dishes is stored;   a washing chamber to receive the dishes during the wash cycle;   a sorption drying device including a sorption system with a reversibly dehydratable material; and   a water feed device having a hot water feed and a cold water feed, the hot water feed to receive hot water from an external hot water supply and the cold water feed to receive cold water from an external cold water supply;   wherein the at least one washing program has at least one first program step to wash the dishes using the hot water from the external hot water supply; and   wherein the at least one washing program has at least one second program step to wash the dishes using the cold water from the external cold water supply.   
     
     
         2 . The dishwasher of  claim 1 , wherein the dishwasher is a domestic dishwasher. 
     
     
         3 . The dishwasher of  claim 1 , wherein, for the at least one second program step, the cold water is heated by waste heat that is produced during desorption of the sorption system. 
     
     
         4 . The dishwasher of  claim 1 , wherein the sorption drying device has an air conduction system to generate an air flow from the sorption system into the washing chamber, the air flow being generated in the at least one washing program during desorption of the sorption system to thereby heat the cold water from the external cold water supply that is provided to wash the dishes by means of waste heat that is produced during the desorption. 
     
     
         5 . The dishwasher of  claim 1 , wherein the at least one washing program has at least one cleaning step to wash the dishes, in which the cold water from the external cold water supply, which is heated by waste heat produced during desorption, is applied on the dishes. 
     
     
         6 . The dishwasher of  claim 1 , wherein the at least one washing program has a pre-wash step to wash the dishes, in which the hot water from the external hot water supply is applied on the dishes in preparation for a cleaning step. 
     
     
         7 . The dishwasher of  claim 1 , wherein the at least one washing program has an intermediate wash step to wash the dishes, in which, after a cleaning step, the hot water from the external hot water supply is applied on the dishes to remove detergent from the dishes. 
     
     
         8 . The dishwasher of  claim 1 , wherein the at least one washing program has a rinsing step to wash the dishes, in which the cold water from the external cold water supply is applied on the dishes. 
     
     
         9 . The dishwasher of  claim 1 , wherein the at least one washing program has a rinsing step to wash the dishes, in which the hot water from the external hot water supply is applied on the dishes. 
     
     
         10 . The dishwasher of  claim 1 , wherein a free flow path is associated with at least one of the hot water feed and the cold water feed. 
     
     
         11 . The dishwasher of  claim 1 , wherein the hot water feed has a hot water valve and the cold water feed has a cold water valve, and wherein the hot water valve and the cold water valve are controlled independently of each other by way of the sequencing controller. 
     
     
         12 . The dishwasher of  claim 11 , wherein at least one of:
 the hot water valve is arranged at an upstream end of a hot water hose and secured to a connecting piece of the external hot water supply; and   the cold water valve is arranged at an upstream end of a cold water hose and secured to a connecting piece of the external cold water supply.   
     
     
         13 . The dishwasher of  claim 1 , wherein a downstream end of a hot water hose and a downstream end of a cold water hose are connected in a liquid-conducting manner to a feed hose by way of a link, and wherein the feed hose is connected to a connecting piece that is fixed to a housing of the dishwasher. 
     
     
         14 . A method for controlling at least one wash cycle for cleaning dishes by means of at least washing program stored in a sequencing controller of the dishwasher, the dishwasher having a washing chamber for receiving dishes that are to be cleaned during the at least one wash cycle and a sorption drying device that includes a sorption system with a reversibly dehydratable material, the method comprising:
 utilizing, in at least one first program step of the least one washing program to wash the dishes, hot water from an external hot water supply; and   utilizing, in at least one second program step of the least one washing program to wash the dishes, cold water from a cold water supply.   
     
     
         15 . The method of  claim 14 , wherein the dishwasher is a domestic dishwasher. 
     
     
         16 . The method of  claim 14 , wherein, for the at least one second program step, the cold water is heated by waste heat that is produced during desorption of the sorption system.
