Description

Description A DISHWASHER AND A CONTROL METHOD
[001] This invention relates to a dishwasher with an improved washing performance and a control method thereof.
[002] In dishwashers, the washing process is accomplished by spraying water, simultaneously or consecutively, from the lower and upper sprayers to the items to be washed which are placed onto the lower and upper baskets. Since, generally, very dirty dishes are placed to the lower basket and slightly dirty dishes to the upper basket; the lower sprayer is supplied with high-pressure water while the upper sprayer is supplied with low-pressure water. Usually, the lower and upper sprayers are operated consecutively, and by alternately supplying the sprayers, water and energy is used to heat the water are saved.
[003] In the European Patent Application EP 1029496, in a dishwasher, the number of revolutions of the circulating pump is reduced during a changeover from one sprayer or group of sprayers to another.
[004J In the European Patent Application EP 0943282, in a dishwasher, an interval program is selectable; in a first interval only the upper spraying lever and in a secund interval only the lower spraying lever is supplying rinsing liquid and the number of revolutions of the pump motor is adjustable as a function of the respective interval.
[005] In the European Patent Application EP 1029498, in a dishwasher, the revolution rate of the circulating pump is regulated according to the varying supply amount, during a changeover from one sprayer or group of sprayers to another.
[006] In the European Patent Application EP 1029499, in a dishwasher, during the operating of the lower sprayer or group of sprayers, the number of revolutions of the circulating pump is set to a higher value than for the upper sprayers.
[007] The aim of the present invention is the realization of a dishwasher and a control method thereof wherein water is saved and the washing performance is increased.
[008] The dishwasher and the control method thereof, realized in order to attain above mentioned aim of the invention has been illustrated in the attached drawings, wherein;

[024] The dishwasher (1) comprises a washing tank (2) where the items to be washed are placed in, a sump (3) at the bottom of the washing tank (2), where the water in the washing tank (2) accumulates during the washing process, a heater (7) used to heat the washing water, which preferably operates during the circulation of the washing water, a circulating pump (4) which supplies the water in the sump (3) back to the washing tank (2) and, is driven by an electi ie motor with variable speed, a multi-way valve (5) at the outlet of the circulating pump (4) which provides that the water to be send to both or either one of the lower and upper supply lines, a discharge pump (6) whereby the water accumulated in the sump (3) at the end of the washing process, is discharged out of the dishwasher (1), a filter (8) which prevents the dirt particles from reducing the washing efficiency by entering the circulation, more than one baskets (11, 1 1 1) where the items that are washed are placed, a high flow rate spraying ami (12) used for very dirty dishes, wherein the water is sprayed at a high flow rate by operating the circulating pump (4) mostly at a high revolution rate and, a low flow rate spraying ami (112) used for slightly dirty dishes, wherein the water is sprayed at a low flow rate by operating the circulating pump (4) mostly at a low revolution rate.
[025] In the dishwasher (1), while the spraying arms (12, 112) are operated consecutively, the number of revolutions of the circulating pump (4) is kept constant during a changeover from the high flow rate spraying arm (12) to the low flow rate spraying arm (112) and from the low flow rate spraying arm (112) to the high flow rate spraying arm (12), whereas the number of revolutions of the circulating pump (4) is changed before or after a changeover from one spraying arm (12, 112) to another, at a different time than the changeover period.
[026] In order to explain the control method of the dishwasher (1), the subject of the present invention, the numbers of revolutions of the circulating pump (4), the cycle times and the amounts of water spent at these times, during the consecutive operating of the spraying arms (12, 112), are denoted as follows;
[027] Nl : is the number of revolutions of the circulating pump (4), for the spraying arms (12, 112) to spray water at a high flow rate. [028] N2 : is the number of revolutions of the circulating pump (4), for the spraying arms (12, 112) to spray water at a low flow rate.
[029] Tl : is the predetermined cycle time of the spraying arm (12) which mostly sprays water at a high flow rate, during consecutive operating.
[030] T2 : is the predetermined cycle time of the spraying arm (112) which mostly sprays water at a low flow rate, during consecutive operating.
[031] P : is the changeover period when the cycle time of one of the spraying arms (12, 112) ends and the cycle time of the other one begins.
[032] #T1 : is the predetermined time interval in one cycle time (Tl) of the high flow rate spraying arm (12) when the said spraying arm is supplied with water at a low flow rate, during consecutive operating.
[033] #T2 : is the predetermined time interval in one cycle time (T2) of the low flow rate spraying arm (112) when the said spraying arm is supplied with water at a high flow rate, during consecutive operating.
[034] According to the dishwasher (1) control method with respect to the present invention, while the spraying arms ( 12, 1 12) are operated consecutively, the circulating pump (4) is operated at a high revolution rate (N 1 ) for a period of Tl - ffT\ whereas it is operated at a low revolution rate (N2j lor a period of T1, considering the high lluvv rate spraying arm (12). At the changeover period (P), while the circulating pump (4) continues to operate at a low revolution rate (N2), the cycle time (Tl ) of the high flow rate spraying arm (12) ends and the cycle time (T2) of the low flow rate spraying arm (112) begins. The circulating pump (4) is operated at a low revolution rate (N2) for a period of T2 - #T2 whereas it is operated at a high revolution rate (Nl) for a period of #T2. At the changeover period (P), while the circulating pump (4) continues to operate at a high revolution rate (Nl), the cycle time (T2) of the low flow rate spraying ami (112) ends and the cycle time (Tl) of the high flow rate spraying ami (12) begins (Fig.3).
[035] It is achieved that the vibration and the noise are prevented as a result of the fact that the changeover between the spraying arms (12, 112) and the change of the number of revolutions of the circulating pump (4) are carried out at different times; it is also achieved that the water in the sump (3) does not fall below a certain level by decreasing the number of revolutions of the circulating pump (4) for a period of #T1 inside the cycle time (Tl) of the high flow rate spraying arm (12) and that the filter (8) is washed as a consequence of the rise of the water level during the said period (Tl) and that the effectiveness of the water jet as removing dirt is increased by increasing the number of revolutions of the circulating pump (4) for a period of #T2 inside the cycle time (T2) of the high flow rate spraying arm (112) and, since the mentioned period (T2) is kept short, the fragile load is prevented from getting damaged.
[036] In another application of the present invention, while the number of revolutions of the circulating pump (4) is changed in the cycle time (Tl) of the high flow rate spraying arm (12), it is kept constant in the cycle time (T2) of the low flow rate spraying arm (112). In this application, the high flow rate spraying arm (12) is operated while the circulating pump (4) is at a high revolution rate (Nl), whereas the revolution rate is decreased (N2) at the end of the cycle time (Tl) for a period of #T1 and, at the changeover point (P) while the circulating pump (4) continues to operate at a low revolution rate (N2), the cycle time (T2) of the low flow rate spraying arm (112) begins, and it ends with the same revolution rate (N2) (Fig. 4).
[037] In another application of the present invention, while the number of revolutions of the circulating pump (4) is changed in the cycle time (T2) of the low flow rate spraying arm (112), it is kept constant in the cycle time (Tl) of the high flow rate spraying arm (12). In this application, the low flow rate spraying arm (112) is operated while the circulating pump (4) is at a low revolution rate (N2), whereas the revolution rate is increased (Nl) at the end of the cycle time (T2) for a period of #T2 and, at the changeover point (P) while the circulating pump (4) continues to operate at a high revolution rate (Nl), the cycle time (Tl) of the high flow rate spraying arm (12) begins, and it ends with the same revolution rate (N l ) (Fig. 5).
[038] In another application of the present im ention, it is achieved that fur the period // IT, the spraying arms (12, 112j are operated simultaneously at the same revolution rate (N2) by also supplying the low flow rate spraying arm (1 12) via a multi-way valve (5) during the period #T1 when the flow rate of the water sprayed by the high flow rate spraying arm (12) is reduced, and similarly, that for the period #T2, the spraying arms (12, 1 12) arc operated simultaneously at the same revolution rate (Nl) by also supplying the high flow rate spraying arm (12) via a multi-way valve (5) during the period #T2 when the flow rate of the water sprayed by the low flow rate spraying ami (12) is increased, and thereby it is accomplished to prevent the noise generated at the multi-way valve (5) and water-carrying pipes as a result of the sudden flow acceleration at the time of a changeover from one spraying arm (12, 112) to another during consecutive operating (Fig. 6).
[039] In the dishwasher (1), the subject of the present invention, it is achieved to prevent the noise generated as a result of the sudden flow acceleration at the time of a changeover from one spraying arm (12, 112) to another, by fixing the number of revolutions of the circulating pump (4) during the changeover and, to increase the washing performance by changing the revolution rate of the circulating pump (4) at predetermined time intervals inside the cycle times of the spraying arms (12, 112).
