Abstract

The present invention relates to a dishwasher (1) wherein the irritating odor that dissipates as the result of long keeping of the dirty dishes in the tub (2) with the door closed between two consecutive operations like operating the dishwasher once a week, is prevented and a control method thereof.

Description

  • The present invention relates to a dishwasher and a control method thereof, in which the dishes kept waiting to be washed are prevented from producing an irritating odor.
  • When the daily amount of dishes put into the dishwasher is small, the users do not start the washing program and choose to wait until the dishwasher is full. An odor is produced when the pre-wash waiting period of the dishes in the dishwasher is long, and the odor dissipates to the medium in an irritating manner when the closed door of the dishwasher is opened for the purposes of adding in the daily dishes. Sometimes the users hand wash the dishes according to their degree of dirt and put the dishes in the machine after removing the rough dirt. In state of the art chemical substances which give off pleasant odors are used for preventing the odor of the dishes kept inside the dishwasher without being washed, but these chemical substances can stay on the washed dishes and pose a threat to health.
  • In the French Patent no. FR2547733 a plastic disk for improving odors is described which is utilized in a dishwasher, positioned in the basket of the dishwasher, impregnated with an odoriferous chemical substance preventing the irritating odors that develop when dishes are kept waiting prior to washing.
  • In the United States of America Patent Application no. US2003221709, an odor eliminating chemical substance is put inside a casing with a shutter, arranged within the dishwasher and the shutter is opened when required by a driving device to release the odor eliminating substance over the dishes.
  • In the International Patent Application no. WO0309982, the washing water is electrolyzed by utilizing an electrolysis device situated inside a dishwasher and the washing performance is enhanced.
  • The aim of the present invention is the realization of a dishwasher and the control method thereof, in which the dishes kept waiting prior to washing are prevented to produce an irritating odor with a very small amount of energy consumption.
  • The dishwasher and the control method realized in order to attain above mentioned aim of the present invention is illustrated in the attached figures, where:
  • FIG. 1—is the schematic view of a dishwasher.
  • Elements shown in the figures are numbered as follows:
  • 1. Dishwasher
  • 2. Tub
  • 3. Sump
  • 4. Heater
  • 5. Circulation pump
  • 6. Discharge pump
  • 7. Control unit
  • 8. Start button
  • 9. Odor detector
  • 10. Measuring chamber
  • 11. Indicator
  • 12. Odor eliminating substance chamber
  • 13. Clock circuit
  • The dishwasher (1) comprises a tub (2) into which dishes to be washed are placed, a sump (3) where wash water is collected, a heater (4) utilized to heat the wash water, a circulation pump (5) which provides the circulation of the wash water, a discharge pump (6) which drains the wash water at the end of the washing process and a control unit (7).
  • When the dishwasher (1) operates, the control unit starts the main washing program (A) comprising of cold-hot washing, rinsing and drying steps and a short term odor eliminating washing program (13) starts independent from the main washing program (A) either upon user's demand for preventing the heavy odor produced when dishes are kept waiting for a long time or automatically when the developing odor level rises.
  • The odor eliminating washing program (B) is a mini-washing program that performs all or some of the steps of the main washing program (A) for shorter periods and at lower temperatures. The complete odor eliminating washing program (B) is short-term, for example 5 minutes, and only removes the dirt of the dishes kept waiting in the dishwasher that can produce an odor with a minimum amount of energy consumption.
  • In the preferred embodiment of the present invention, the dishwasher (1) comprises a starting button (8) to allow the odor eliminating washing program (B) to be started by the user.
  • In another preferred embodiment of the present invention, the dishwasher (1) comprises an odor detector (9) that detects the odor spreading from the dishes kept waiting in the tub (2) and an indicator (11) which gives off an audio and/or visual warning if the odor amount detected by the odor detector (9) exceeds a preset limit.
  • In the above mentioned embodiments of the present invention, when the odor amount detected by the odor detector (9) exceeds a preset limit, the indicator (11) is enabled by the control unit (7) to give off an audio and/or visual warning. Upon receiving the warning from the indicator (11), the odor eliminating washing program (B) is initiated by the user pressing on the starting button (8).
  • In another embodiment of the present invention, the dishwasher (1) comprises a measuring chamber (10) where the odor detector (9) is positioned, convenient for gathering a measurement sample of the medium air inside the tub (2).
  • In another embodiment of the present invention, the odor eliminating washing program (B) is automatically started by the control unit (7) when the odor amount detected by the odor detector (9) exceeds a preset limit, warning the user by the indicator (11) or without warning given via the indicator (11).
  • In yet another embodiment of the present invention, the information on time periods of expensive and cheap rates of electric consumption costs is loaded to the control unit (11) as input and when the automatic starting of the odor eliminating program (B) corresponds to the expensive rate period, the odor eliminating program (B) does not start but is postponed until the following cheap rate period. In this embodiment, the control unit (11) comprises a clock circuit (13) having timing information.
  • The irritating odors produced by the dishes kept waiting for a long time prior to washing in the dishwasher (1) are detected by the odor detector (9) and a signal is sent to the indicator (11) warning the user in the manually started implementation. The user, when warned by the indicator (11), will start the odor eliminating program (B) by pressing on the starting button (8) if so desired. In the automatically started implementation, the odor eliminating program (B) starts automatically when the odor amount detected by the odor detector (9) is above a preset limit. If the automatic starting time is within the expensive rate time period input in advance in the control unit (7), the odor eliminating program (B) does not start but starts automatically in the next cheap rate time period.
  • In another embodiment of the present invention, the dishwasher (1) comprises an odor eliminating substance chamber (12) into which odor eliminating chemical substances are put.
  • The odor eliminating washing program (B) comprises the steps of taking in water, preferably into the sump (3), opening the odor eliminating substance chamber (12) to mix the odor eliminating substance with the wash water, heating the wash water to a low temperature by the heater (4), circulating with the circulation pump (5) and draining the wash water with the discharge pump (6).
  • When the odor eliminating washing program (B), started by the user or automatically, is completed, the dishwasher (1) again goes into the pause mode; the user has to start the main washing program (A) when the dishes are desired to be washed.
  • In cases when the dishwasher (1) is used with long intervals, for example once a week, the odor eliminating washing program (B) is employed to prevent the dishes that are kept waiting from producing a heavy odor.
  • A better washing performance is achieved by the main washing program (A) when the odor eliminating washing program (B) is employed since the heavy dirt on the dishes are removed before drying up.
