Definitions
- the present invention relates to a device for indicating the exhaustion of a cleaning or cleaning aid introduced into a dishwasher for several rinsing cycles, and to a method for using such devices.
- the problem here is to indicate the exhaustion of cleaning or cleaning aids when the consumer is to buy a corresponding new product and put it in the dishwasher.
- chemical fatigue indicators have been developed which, for example, are to indicate to the consumer the exhaustion of the cleaning or cleaning aid by changing the color of an indicator.
- these color displays are unreliable and the color of the indicator also depends not only on the number of rinses, but also on the general conditions of the respective rinsing process (temperature, duration, presence of certain ingredients in cleaning agents, etc.).
- Another solution is to add cleaning aids to corresponding single-dose cleaning agents, so that the consumer receives a new cleaning aid when buying a new package of cleaning agent.
- This has the disadvantage that one can certain package sizes for the detergent is bound; in addition, a separate sale of the cleaning aid is not possible in this way.
- the invention is therefore based on the object of creating a display device of the type mentioned which is free from the disadvantages mentioned and moreover is easy and inexpensive to produce, is technically improved, more user-friendly and also inexpensive.
- the subject of the present invention is a device for indicating the exhaustion of a cleaning or cleaning aid introduced into a dishwasher for a plurality of rinsing cycles, in which a display device is arranged on or in the dishwasher that shows the consumer the exhaustion of the cleaning or cleaning aid displays.
- the device contains a display device, which preferably has no active substances for the cleaning process.
- a display device which preferably has no active substances for the cleaning process.
- Devices in which the indication of the exhaustion of a cleaning or cleaning aid that has been introduced into a dishwasher for several rinsing cycles merely consists in the fact that this cleaning or cleaning aid is used up are not the subject of the present invention.
- a display device is preferably used, the mode of operation of which is not, or not solely, chemically based. Decolorization of dyes or the like are preferably not included or not alone as a display device. Preferred devices according to the invention are therefore characterized in that the display device is a mechanical and / or magnetic and / or electrical and / or electronic display device.
- devices are preferred whose display devices can be read not only when the dishwasher is open, but also when it is closed.
- Preferred devices according to the invention are therefore characterized in that the display device is arranged outside the operating space of the dishwasher.
- the consumer can use the display device to exhaust the cleaning or cleaning aid not only as a function of time but also as a function of the number of Show rinse cycles, the type of rinse cycle, etc.
- the parameter that is selected to control the display is in Selectable depending on the desired precision (selectivity) of the display or on the cleaning agent or cleaning aid to be determined.
- devices according to the invention are preferred in which a display device is arranged on or in the dishwasher, which indicates to the consumer the exhaustion of the cleaning or cleaning aid as a function of time.
- the consumer activates the device as soon as he introduces a new cleaning or cleaning aid into the dishwasher.
- the display device indicates that a renewal of the cleaning or cleaning aid is required.
- the output of a signal on the display device is preferred if a period of two to twenty weeks, preferably three to 15 weeks and in particular four to 12 weeks has passed.
- the display device Regardless of the design of the display device, d. H. whether it is built electronically or mechanically, one can further develop the invention with the display device the consumer the exhaustion of the cleaning or cleaning aids not only depending on the time, but also in dependence on other parameters that have a higher selectivity for the consumption of By owning, displaying.
- a combination of the measurement of time and other parameters in order to draw conclusions about the degree of exhaustion of the cleaning or cleaning aid has hitherto been unknown in the prior art because the consideration of both parameters does not appear to the consumer to be possible.
- the display device is connected to an arrangement which is attached to a movable part and which triggers a switching operation during this movement.
- an arrangement which is attached to a movable part and which triggers a switching operation during this movement.
- certain movements correlated with the number of cleaning processes can be detected and used as a trigger for a display signal.
- a switching process can be triggered, which in turn causes a display in the device according to the invention.
- a switching process is without that Movement of mechanical parts possible; especially if you use a magnetic or electrical arrangement that also causes a display.
- Such a display device is evidently simpler, more robust and is preferred by the end user.
- Another alternative embodiment of the device according to the invention is also possible, in which the switching process is triggered by the movement of two parts of the device relative to one another, provided that their movement is necessary for a cleaning process.
- a display device is arranged on or in the dishwasher, which indicates to the consumer the exhaustion of the cleaning or cleaning aid as a function of the number of times the door of the dishwasher is opened.
- the consumer activates the device as soon as he introduces a new cleaning or cleaning aid into the dishwasher.
- the display shows that the cleaning or cleaning aid needs to be replaced.
- the output of a signal after 40 to 1200, preferably after 80 to 1000 and in particular after 120 to 800 opening operations is possible and preferred.
- the selectivity of this device is higher because the number of times a dishwasher is opened for a certain number of cleaning operations is relatively constant. However, fluctuations can also occur here, for example if the dishwasher is only opened once per wash cycle when there is a heavy load at parties or family celebrations, or when the load is low (repeated setting of individual crockery parts over a longer period) frequently.
- Preferred devices according to the invention are characterized in that a display device is arranged on or in the dishwasher, which indicates to the consumer the exhaustion of the cleaning or cleaning aid as a function of the number of movements of at least one crockery basket.
- the display After a defined number of movements of at least one crockery basket, the display indicates that the cleaning or cleaning aid needs to be replaced.
- the output of a signal after 10 to 800, preferably after 20 to 600 and in particular after 40 to 400 movements is possible and preferred.
- the number of cleaning operations carried out can also be used as a control variable, for example by using the on / off switch of the dishwasher as a moving part.
- Devices according to the invention, in which a display device is arranged on or in the dishwasher, which indicates to the consumer the exhaustion of the cleaning or cleaning aid as a function of the number of cleaning programs carried out, are preferred.
- control variables can also be combined with one another. So it is possible, for example, the signal depending on the time and the number of times the door of the dishwasher opens, depending on the time and number of movements of the dishwasher baskets, depending on the time and number of cleaning operations Dishwasher, depending on the number of opening operations of the dishwasher door and the number of movements of the dishwasher baskets and depending on the number of opening operations of the dishwasher door and the number of cleaning operations of the dishwasher.
- Devices which are particularly preferred according to the invention are characterized in that the display device is connected to an arrangement which is attached to a movable part of the dishwasher and upon its movement triggers a switching operation. As a result of the switching process, the electrical pulse is available in the electronic display device in order to carry out a count and also to display it.
- the arrangement which is preferably attached to a movable part of the dishwasher (door, crockery basket, switch, closure flap of the metering chamber, etc.) is integrated in the display device in devices preferred according to the invention.
- the electronic display device can not only measure the time lapse, but instead of or in combination with this flow also and additionally the amount of cleaning or cleaning aid consumed and the result of which is displayed. Although this measurement takes place indirectly via the movement of mechanical parts relative to one another, it nevertheless reliably and fairly closely approximates the actual amount consumed.
- the door of the dishwasher for example, was mentioned above as a movable part.
- the arrangement has a reed switch and that a magnet is attached to a movable part of the dishwasher.
- the part connected to the dishwasher can be any corresponding part to which a magnet can be conveniently and technically simply attached, which can trigger the switching operation mentioned above when the reed switch approaches or moves away. It is known to use very small reed switches when low powers are sufficient for the desired functions. If it is an electrical pulse or the display of the field of a display device or a light source, for example an LCD, very low electrical outputs and very small reed switches are sufficient.
- the magnet is attached to the door and / or to a crockery basket and / or to the program selector switch and / or to the on / off switch.
- a display device which has a viewing window with a plurality of display fields arranged next to one another and preferably a reset button. Accordingly, preferred devices according to the invention are characterized in that the display device is a viewing window with a plurality of display fields arranged side by side.
- the display device Before the display device of the invention is put into operation, energy can be saved as long as, for example, the device is sold unsold in a warehouse. After purchase, the consumer can activate the display device by pressing the reset button and track the desired functions by looking at the display fields.
- a transparent pane, a plate, a panel or the like as a viewing pane one or more display fields are the information carriers when they are visible, blinking or are invisible. Instead of display fields, digital LEDs can also be used.
- the time units and / or units for opening operations etc. can be set to days, weeks, months or years or number I, depending on the consumer's request and purpose.
- the display device comprises a liquid crystal display (LCD).
- LCD liquid crystal display
- Another object of the present invention is a method for indicating the exhaustion of a cleaning or cleaning aid introduced into a dishwasher for several rinsing cycles, in which a device according to the invention is attached to or in the dishwasher.
