Description

Description Household appliance with programmable control module

The present invention is a household appliance, in particular washing machine or dishwasher, with an electronic program control for controlling Spülprogrammabläufen with a programmable control module having an interface for programming at least one of the program control executable Spülprogrammablaufs.

Usually, in domestic appliances, in particular in a dishwasher, in the course of the rinsing operation, one or more rinsing operations are carried out with heated rinsing liquid in order to clean the dishes located in the dishwasher. After the last rinsing process usually takes place a rinse phase, followed by a drying process followed to dry the items to be washed. These and iele other modes are put together in specific adapted to the type and amount of the dishes to be cleaned Spülprogrammabläufen. The control of the Spülprogrammabläufe is usually carried out by an electronic program control, in the electronic components usually several Spülprogrammabläufe are stored.

[003] Such program controls are often sourced from the dishwasher manufacturer via suppliers in the form of program control modules in which the desired wash programs are already preprogrammed. After installation of the program control module in the Geschrrspülmascline a subsequent programming of the program control or a change in the program control preprogrammed Spülprogrammabläufe is not or only with increased effort possible, for example, a disassembly of essential parts of the dishwasher is required or the program control must, in particular considerable installation effort to be expanded, because the program control is located inside the household appliance.

The object of the present invention is to provide a dishwasher, the program control even after the construction of the program control module in the dishwasher programming the program control and a subsequent change in the program control preprogrammed Spülprogrammabläufe in a simple and inexpensive way allows.

[005] This object is achieved by the dishwasher according to the invention having the features according to claim 1. Advantageous developments of the present Invention are characterized in the subclaims 2 to 12.

In the household appliance according to the invention, in particular washing machine or dishwasher, an electronic program control for controlling Spülprogrammabläufen is provided which comprises a programmable control module having an interface for external programming of at least one executable by the program control Spülprogrammablaufs, wherein a programming without disassembly of parts of the household appliance is executable. Under the dismantling of parts of the household appliance are in the context of this patent application essential parts, eg. B. side or rear walls understood. For example, with an interface accessible from the outside of the exterior, disassembly of a smaller coverage of the interface, e.g. B. a connector protection flap, may be required.

Preferably, the interface is directly contactable from outside the dishwasher, d. H. The interface is accessible from the outside without disassembly of essential parts of the household appliance.

According to the present invention, it is possible due to the integration of a contactable directly outside of the dishwasher interface for external programming Spülprogrammabläufen on the control module of the program control to install the program control without preprogramming in the household appliance and only in one of the last steps or after completion to program the production of the household appliance. The direct contactability of the interface of the programmable control module means in this context that the interface can be contacted even when installed from outside the household appliance, without structural changes or a significant installation effort on the domestic appliance are required. As a result, the program control module can first be opened by the ZuEeferer as an unprogrammed control and the complete installation of the rinsing program sequences can take place during or after the assembly of the household appliance, without having to make any structural changes to the domestic appliance. Due to the direct contactability of the interface of the programmable control module, it is also possible, according to the present invention, for the program control module to be preprogrammed by the supplier according to the customer's wishes. This reduces the number of variants of household appliances, in particular dishwashers, in the production since different levels of dishwashing detergent can be added to the programmable control module. program sequences can be programmed and for the final assembly of the dishwasher only so-called hardware variants must be planned.

The household appliance according to the invention thus has the advantage that the programming of the program control can be made even after completion of the manufacturing process or in the program control preprogrammed Spülprogrammabläufe even after the manufacturing process still changed, replaced or supplemented. As a result, the vertical integration in the final assembly and the assembly effort is reduced overall and the product flexibility is increased. The programmable control module with the directly contactable from outside of the household appliance interface also allows fast and flexible Ogrammierung or AktuaEsierung of particular rinse programs.

In a preferred embodiment of the present invention, the interface of the programmable control module comprises a number of electrical contacts for external programming of the control module, which are preferably designed as plug-in connections. However, it is also possible to design the interface of the programmable control module as an infrared interface or as a wireless radio link. Each of these types of interfaces allows easy programming of the control module before, during, or after production of the home appliance; but also a reprogramming or supplementation of the existing already in the control module program flows, in particular Spulprogrammabl, after commissioning of the household appliance via the interface of the program control possible.

In this case, it is particularly advantageous if the programmable control module comprises the electronic components required for program control, and preferably at least one microprocessor and / or storage means. In the memory means, for example, executable by the program control rinse program sequences can be stored, which were previously transmitted via the interface for programming the program control. By way of example, the microprocessor is capable of executing the wash program sequences stored in the programmable control module and of giving corresponding control signals to the components of the household appliance that are indicated during the flushing process. Additionally or alternatively, the microprocessor may include an operating system for programming the control module.

Advantageously, the programmable control module also includes a network input filter for filtering high frequencies. The net input filter is used for Suppression and the electromagnetic compatibility of the household appliance. A particularly efficient effect can be achieved if the network input filter filters out the frequencies in the range from 150 kHz to 30 MHz or from 30 MHz to 300 MHz. As a result, almost all electronic components required for the electrical connection of the program control can be accommodated in the programmable control module, which also facilitates the checking of the electromagnetic compatibility (EMC) of the dishwasher.

[013] Sometimes the electrical energy supply in household appliances is provided by a mains connection cable via an electrical connection designed for higher current intensities. For this purpose, the household appliances are usually equipped by the manufacturer with a device-mounted fixed power cord. In order to connect the device to the electrical mains, then only the plug of the power cable must be plugged into the socket. However, the fixed device-side connection of the power cord has the disadvantage that for untercriedEche power plugs, for example, in various countries already factory a corresponding power cord must be mounted. In a further preferred embodiment of the present invention, the programmable control module therefore includes a power connector for powering the programmable control module and the home appliance. Such IEC connectors allow the connection of a mains connection cable, the device side has a plug designed to complement the IEC connector and the mains side has a suitable plug for power mains connection plug. As a result, the dishwasher according to the invention, the appropriate power cord can be enclosed after production or ausgeϊefert without a fixed power cord and the appropriate power cord, for example, be supplemented by the country's sales.

The programming of the control module or a functional check after the construction of the control module in the dishwasher according to the invention is particularly facilitated when the IEC connector and the interface for external programming of the programmable control module can be contacted via a combination plug. The combination plug comprises both the complementarily designed counterpart to the IEC connector and the complementarily designed counterpart to the interface of the programmable control module. By having both the complementarily formed counterpart to the cold rätestecker and the complementarily formed counterpart to the interface in the combination plug are combined to form a Briheit, the contacting of the programmable control module can be particularly easy and practical in a hand movement.

Expediently, an electrical connection is provided for the electrical connection of the programmable control module with the dishwasher, which is preferably designed as a group plug with a number of electrical contacts. In this way, the electrical connection between the programmable control module and the dishwasher can be made with only one plug, which facilitates the assembly or replacement of the control module.

[016] The control module according to the invention comprises at least one board on which the electronic components required for the program control are arranged. The board has an electrical connection to make the connection between the program control and the dishwasher. For this purpose, a portion is preferably formed on the edge of the board as an electrical connection with a number of electrical contacts. With this section at the edge of the board, the programmable control module can be used in a fast and easy way when mounting in a complementary formed slot in the household appliance.

The integration of the interface for programming the program control and the IEC connector on the programmable control module is advantageously reaEsiert that their placement allows contacting from outside the home appliance. For this purpose, the programmable control module is preferably installed in the floor pan of the dishwasher and arranged so that the interface for programming the control module can be contacted by the rear wall of the floor pan. As a result, the household appliance can be supplied, for example during the final functional check after the production process, via the cold burr plug in the programmable control module with electrical power and programmed via the contacting of the interface.
