Description

METHOD FOR CHECKING PROPER FUNCTIONING OF A HOUSEHOLD APPLIANCE
DESCRIPTION
Technical field
The object of the present invention is a method for checking proper functioning of a household appliance for washing and/or drying. There are known household appliances that are capable of generating diagnostic information during normal operation, that is, during the execution of the main function of the appliance, for example the washing cycle for a washing machine. This makes it possible to have information that can be downloaded by the service technician or transmitted to a remote service centre.
One drawback of a design solution such as this is that the user must carry out a predetermined washing cycle in which the damaged component is involved in order to become aware of a malfunction.
An additional drawback is related to the fact that in any case the user must contact a specialized service centre or call a technician in order to find out if and which component is damaged.
There is also a known washing machine of the type described in patent no. WO200815471 1 . The patent describes a check sequence to be carried out prior to the start of the washing program. The machine enters this mode by means of a series of timer combinations that are incompatible with normal operation. During the check, the rotary button of the timer advances correspondingly with the function being tested and stops when it detects a malfunction. By means of a table, the technician can identify the type of malfunctioning associated with the table based on the position in which the rotary button of timer stops.
One drawback of this design solution relates to the fact that a technician called in to correct a problem might only understand that there is malfunctioning with a given function and thus deduce that the problem is with a given component. However, if the damage is extensive, involving a plurality of components, the technician would not have any pertinent information with the result that a component might be replaced without resolving the issue. Moreover, the check sequence comprises the intervention of a technician, given that the activation of the check sequence requires knowledge of the machine that is beyond the normal knowledge of the average user. Therefore, a technician contacted for repairs needs to travel to the location where the household appliance is installed, launch the checking procedure and then eventually return there if he/she does not have the component that needs to be replaced.
Aim of the invention
An aim of the present invention is to make available a household appliance that makes it possible to overcome the above-mentioned drawbacks and in particular, that allows the user to check, in an extremely simple and immediate manner, whether the household appliance and the various functions thereof are operating properly.
The defined technical task and the specified aims are substantially achieved by a household appliance comprising the technical characteristics set forth in one or more of the appended claims.
Brief description of the drawings

Detailed description of preferred embodiments
A household appliance for washing and/or drying items is indicated by the reference number 1 in the accompanying figure.
This household appliance 1 comprises means 2 for carrying out a test cycle. In practice, the test cycle can execute a succession of activations of the various functions of the household appliance for brief intervals of time or even simulate, for brief intervals of time, actual washing and/or drying cycles. If the household appliance 1 is a washing machine, it is normally connected to the water supply to carry out the test cycle The means 2 for carrying out a test cycle substantially comprises the means utilized for carrying out the washing and/or drying programs.
The household appliance 1 comprises means 3 for detecting malfunctions during the test cycle.
The detection means 3 conveniently comprises one or more sensors integrated in the household appliance 1 . These sensors make it possible to control the various functions of the household appliance 1 . For example, the detection means 3 could comprise a temperature sensor, which, at the end of a pre-established interval of time following the switching-on of the electric heating element, checks that the temperature in the washing tub is above a pre-established value. However, this temperature sensor is not an element external to the household appliance, but rather, the same sensor which, during operation of the household appliance, regulates the progress of the washing program as a function of its output. The detection means 3 could further comprise a pressure switch, which, at the end of a pre-established interval of time following the opening of the water load solenoid valve, checks that there is a certain amount of water in the tub. In this case as well, the pressure switch mentioned above is the same pressure switch that enables the execution of the pre-set washing programs.
The household appliance 1 conveniently comprises a control card 6 that activates pre-established components of the household appliance 1 (typically sets of components are activated in a sequence). Conveniently, the control card 6 synchronizes and controls the operation of the implementation means 2 and the detection means 3.
The household appliance 1 comprises a selector 4 that is accessible by a user and dedicated solely to starting said test cycle.
The selector 4 is a button 40 that is independent of other selectors on the household appliance. This button 40 could possibly be a physical button or a touch button, for example on a display that enables navigation among a plurality of commands. In any case, if pressed, this button unequivocally supplies the command to execute the test cycle. Accordingly, at this button 40, the household appliance 1 conveniently comprises an indication (a graphic symbol, a number or letter) that serves as a reminder that this button is used for starting the test cycle. In particular, the user manual for the household appliance 1 indicates the operation of this selector 4 (specifically, of this button 40).
In the preferred solution, the selector 4 is directly accessible by a user. Therefore, it is not protected or concealed by panels that would have to be moved before the desired selector can be reached. This enables it to be easily reached by a user. In fact, the selector 4 is designed to be utilized by a user. Therefore it is not hidden in points that are difficult to reach so as to permit access only to technicians when performing maintenance procedures.
In this regard, the selector 4 is advantageously afforded in a front portion of the household appliance 1 .
In particular, the selector 4 is located alongside other selectors in a zone in which the user interface 5 of the household appliance 1 is afforded. In particular, the selector 4 is integrated in the user interface 5.
The object of the present invention is a method for checking proper functioning of a household appliance 1 for washing and/or drying items.
Conveniently, this household appliance 1 has one or more of the characteristics described hereinabove.
The household appliance 1 performs at least the step of carrying out a test cycle to completion. Conveniently, the step of carrying out the test cycle to completion comprises testing all the functions provided upon starting the test cycle.
The test cycle is:
- selectable by means of a selector 4 on the household appliance 1 ;
- an alternative to the remaining washing and/or drying programs that can be selected by means of a user interface 5 of the household appliance 1 .
The method conveniently comprises the step of storing any malfunctions detected during the step of carrying out said test cycle.
The method comprises the step of supplying output that indicates all malfunctions encountered during the step of carrying out said test cycle. The method further comprises the step of supplying output that indicates all malfunctions encountered during the step of carrying out said test cycle. In this manner it is ensured that the household appliance will complete the test cycle. Therefore, when the data are analysed, a complete overview of the malfunctions will be available, which can help the technician understand the particular cause of a given malfunction (in fact, it could be misleading for a technician to take into consideration only one sign without having the complete picture).
Following the end of said test cycle, output is advantageously supplied indicating the passing or failing of the test cycle.
In a particular design solution, following the end of the test cycle, the malfunction data are transmitted to a remote centre. The remote centre then enables analysis of the data transmitted, identifying the cause of the problem and sending a technician on site, the technician already being equipped with all the spare parts needed to carry out repairs or replacement of parts.
Additionally or alternatively, following the end of the test cycle, the malfunctions can be reported to the user by means of the user interface 5. For example, they could be signalled by a visual indicator such as a display or a plurality of warning lights.
The method conveniently comprises a step of starting said test cycle by activating the sector 4. The selector 4 is accessible by a user and is dedicated specifically to starting said test cycle.
Conveniently, the step of starting said test cycle comprises activation of said selector 4 on a front portion of the household appliance 1 . The frontal position of the selector 4 facilitates its identification and thus the activation thereof by a user.
In the preferred solution, the method comprises the step of selecting said test cycle by means of a single procedure for activation of the selector 4 located on the household appliance 1 . This single activation procedure could actually consist of a single movement of the selector 4. For example, if the selector 4 is a button 40, this movement could consist of shifting the button 40.
The step of starting said test cycle comprises the selection of a button 40 that is independent of other selectors on the household appliance 1 .
With the aim of facilitating activation, the step of starting said test cycle comprises that a user directly accesses said selector 4.
The present invention makes it possible to achieve multiple advantages. Firstly, it facilitates the technician who performs repairs by allowing the technician to have an overview that is as complete as possible as regards the malfunctions of the household appliance, avoiding decision-making based on partial or incomplete data.
Secondly it allows a user to start a test cycle completely on his/her own and without possessing specific skills.
The invention thus conceived is susceptible to numerous modifications and variants, all of which falling within the scope of the inventive concept characterizing the invention. Moreover, all details may be replaced with other technically equivalent elements. The materials used, as well as the dimensions, may in practice be of any type, according to needs.
