Abstract:
A dish -washing machine has a control system, which includes means for selection, start-up, and control of a plurality of treatment programs, and a tank (30) for accumulation of water. The programs of the plurality comprise: - at least one program, which includes a step of filling the tank (30) with water; - at least one program, which includes a step of emptying the tank (30) into a wash tub (3) and a subsequent step of treatment of dishes performed using the water discharged from the tank into the wash tub; and - at least one treatment program that does not include steps of treatment of dishes using water discharged from the tank into the wash tub. When the stay time of the water inside the tank is equal to or longer than a prefixed value, there are envisaged operations of: 1) performing a forced emptying of the tank in a step of any program of the plurality that is started after the stay time of the water inside the tank has reached or exceeded the prefixed value; and 2) evacuating from the wash tub the water discharged from the tank following upon the aforesaid forced emptying, without using said water for execution of the step of treatment of dishes.
Abstract:
The present invention relates to an apparatus and method for detecting an error in the measurement of a water level in a washing machine. The apparatus comprises: a water-level sensor for measuring the water level in a wash tub; a water supply/discharge device, which supplies water into the wash tub or discharges water from the wash tub; and a control unit, which controls the water supply/discharge device so as to adjust the actual water level in the wash tub, and which detects an error in the measurement of the water level sensor based on the variation in the water level measured by the water-level sensor during the measurement of the actual water level. According to the present invention, a user may recognize an error in the measurement carried out by the water level sensor, and prevent the outbreak of a fire in advance when the water remaining in an air trap is frozen or the pressure in the air trap changes, and further, the unnecessary waste of water or detergent may be reduced.
Abstract:
A dish washing machine has at least one washing system (51, 52) that has a nozzle system with at least one washing nozzle (13, 13-1, 13-2) for spraying washing, a washing tank (14; 14-1, 14-2) for capturing at least part of the sprayed washing liquid, and a washing pump (11; 11-1, 11-2) for feeding washing liquid collected in the washing tank (14; 14-1, 14-2) to the at least one washing nozzle (13, 13-1, 13-2). A dirt capture system (70) separates dirt particles from the sprayed washing liquid flowing back into the washing tank (14; 14-1, 14-2) as a result of gravity, and a dirty-water pump (74; 74-1, 74-2) is connected for discharging the dirt particles from the dirt capture system (70). A control device (100) is designed for the mutually coordinated activation of the washing pump (11; 11-1, 11-2) and of the dirty-water pump (74; 74-1, 74-2), so that the recirculation circuit of the washing system (51, 52) can be interrupted for a first time span (Tl), and the discharge of dirt particles takes place within this first time span (Tl) or, at the latest upon the expiry of this first time span (Tl), within a second time span (T2). The invention also relates to a corresponding method for the mutually coordinated activation of the pumps (11, 74).
Abstract:
The invention relates to a dishwasher which is designed in the form of a box-type dishwasher or of a conveyor dishwasher (50) and has at least one wash system (51, 52) designed in the form of a recirculation circuit. The wash system (51, 52) has a nozzle system with at least one wash nozzle (13-1, 13-2) for spraying wash liquid onto the wash ware which is to be cleaned, also has a wash tank (14; 14-1, 14-2) for collecting at least some of the sprayed wash liquid, and additionally has a wash pump (11; 11-1, 11-2) by means of which wash liquid collected in the wash tank (14; 14-1, 14-2) is fed to the at least one wash nozzle (13-1, 13-2). There is also a dirt-collecting system (70) which is assigned to the at least one wash system (51, 52) and has at least one tank-covering screen (20; 20-1, 20-2), in order to separate off particles of dirt from the wash liquid which has been sprayed and flowed back into the wash tank (14; 14-1, 14-2) under gravitational force. In order for the particles of dirt which are washed off the wash ware during operation of the dishwasher to be separated effectively from the wash liquid, the dirt-collecting system (70) also has a dirt-collecting region (71) which is arranged in the wash system (51, 52) and is intended for collecting the particles of dirt which have been separated off from the wash liquid with the aid of the tank-covering screen (20; 20-1, 20-2), wherein the dirt-collecting region (71) is open at the top, but closed all the way around the sides, and wherein there is also a dirt- discharging pipe system (72, 73; 72-1, 73-1; 72-2, 73-2) which is connected to the dirt- collecting region (71) and by means of which the particles of dirt collected in the dirt- collecting region (71) are discharged from the wash system (51, 52).
Abstract:
The invention relates to a method for operating a washer which comprises a washing chamber for accommodating goods to be cleaned, said washing chamber having in its lower portion a sump for collecting water during operation of the washer, a water inlet connected to a water tank, preferably to a water tank that is integrally, still preferably detachably, formed with the dishwasher, a pump for circulating water through the washing chamber, and a control unit for controlling a washing process carried out by the washer. In accordance with a first embodiment of the method of the invention, in this method: water is fed from the tank into the sump by the action of the hydrostatic pressure prevailing within the tank; the pressure within the sump or close to the sump is measured; and based on the pressure measurement the speed of the water flow is monitored and the filling level of the tank is determined, and at least one parameter and/or step of the washing process is controlled and/or indicator signals are issued to a user of the washer.
Abstract:
The present invention relates to dishwashers, and more particularly, to a dishwasher and a method for controlling the same, which can measure turbidity of the washing water, and control operation of the dishwasher with reference to the turbidity detected thus, to prevent wasting of water, and optimize a washing time period. The dishwasher includes a sump (100) for holding washing water, a washing pump for pumping the washing water to provide a portion of the washing water to dishes to be washed through a main flow passage (330), and a turbidity sensing means (600) for sensing turbidity of the washing water, wherein the turbidity sensing means (600) is positioned at a sampling flow passage (310) through which the other portion of the washing water passes. The method for controlling a dishwasher includes the steps of putting a washing pump into operation, detecting turbidity of the washing water, adjusting a washing time period preset at a control unit according to the turbidity detected thus, and operating the washing pump according to the washing time period adjusted thus.
Abstract:
A warewash machine includes in-situ tank soil load reduction that involves at least one of: (i) prior to addition of fresh water, draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path until wash liquid level in the collection tank drops below a standard operating level, and thereafter adding fresh water; or (ii) draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path while simultaneously adding fresh water; or (iii) adding fresh water such that wash liquid level in the collection tank rises above a standard operating level, and thereafter carrying out draining of the collection tank.
