BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a washing machine, and more particularly, to a washing machine control method and washing machine using the same, utilizing a memory function to enable the setting of a customized parameters for each of a plurality of courses.
2. Discussion of the Related Art
A washing machine is an apparatus for removing dirt from laundry through such steps as washing, rinsing, and dewatering in accordance with a stored program executed by a microcomputer. Generally, a washing machine is provided with a variety of control features for selecting the desired parameters for running the program. One among such features is a memory feature enabling a user to set the conditions for a custom course for is performing washing, rinsing, and dewatering steps as desired. The memory feature is specifically designed to accommodate the user's most frequently used washing machine settings.
Referring to
The key input unit 10 includes a course control device 11 for inputting a selection of one among a plurality of courses and a parameter control panel 12 for inputting a selection of course parameters, based on the setting of the course control device, using a plurality of parameter keys. For example, by repeatedly pressing a parameter key, the selected function may shift through a predetermined set of parameters for adapting such parameters as washing time, water temperature, and the number of rinsing and dewatering cycles to be performed.
The course control device 11 may be realized as a rotary switch (not shown) for selecting among a plurality of course settings. The selections of the course control device 11 may, for example, include for a “normal” course, a “synthetics” course, a “wool” course, a “blanket” course, a “speed” course, and a “memory” course among others. Here, it should be noted that the memory course is selected in lieu of any of the other courses. Also, though not shown in the drawings, the course control device 11 operates in conjunction with a course execution key, such as a start/pause button, for initiating the execution of the selected course.
In the operation of the memory function of the above washing machine according to the related art, the user first adjusts the rotary switch to select the memory course among the plurality of course settings of the course control device 11 and then inputs a custom parameter selection using the parameter keys of the parameter control panel 12. In doing so, the microcomputer 40 first recognizes the settings of the memory course and then stores the settings of the custom parameter selection in the memory 20. At the time of execution, the user operates the key input unit 10 to select the desired course for execution and presses the start button, whereupon the microcomputer 40 accesses the default conditions corresponding to the selected course and executes the selected course.
Referring to
The step 21 is for determining the parameters of the memory course, that is, for selecting and storing a customized set of course conditions for execution in the step S23 if the memory course is selected and the start button is pushed.
Referring again to
With the current parameters thus displayed, it is determined in a step S21b whether a key input from the parameter control panel 12 is present, indicating the user's desire to set the displayed parameters or to change those already set during a previous operation, and the parameters are displayed accordingly in a step S21c. To save the settings as selected in steps S21b and S21c, the user then operates a “save” function of the key put unit 10, which is typically achieved by merely proceeding to the next step, for example, by pushing the start button. If it is determined in a step S21d that the save function is desired, the parameters as is displayed are stored in a step S21e as the current operating parameters of the memory course.
In the washing machine of the related art as above, however, the memory course is simply one among a plurality of courses, to be selected by the user for execution with or without customizing its parameters. Thus, to operate the washing machine according to the memory course, or to change the settings of the memory course itself, a rotary switch or similar means must first be manipulated, which is inconvenient to users. Moreover, the memory course is merely an optional standard course, i.e., a course with or without changes to the default parameters of the standard course. Hence, the function of the memory course is limited.
SUMMARY OF THE INVENTIONAccordingly, the present invention is directed to a washing machine control method and washing machine using the same that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An object of the present invention, which has been devised to solve the foregoing problem, lies in providing a washing machine control method and washing machine using the same, which enables the user to define a customized set of parameters to achieve a memory function for each of a plurality of courses, to enhance user convenience and to increase the overall flexibility and capability of a memory feature as well as the washing machine itself.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent to those having ordinary skill in the art upon examination of the following or may be learned from a practice of the invention.

To achieve these objects and other advantages in accordance with the present invention, as embodied and broadly described herein, there is provided a method of controlling a washing machine having a memory function using memory means and having course start input means for selectively performing one of a plurality of courses. The method comprises steps of establishing a set of customized parameters for performing each of the plurality of courses; first selecting one of the plurality of courses for execution, the selected course corresponding to one of the set of parameters established in the establishing step; displaying default parameters of the course selected in the first selecting step; clearing the displayed default parameters and displaying, in response to a first selection of the memory function, the customized parameters corresponding to the course selected in the selecting step; and performing, upon an input of the course start means, the selected course according to the displayed parameters. The establishing step is comprised of steps of second selecting, from a predetermined set of parameters, the customized parameters for display; and storing in the memory means the customized parameters selected in the second selecting step in response to a second selection of the memory function.
In another aspect of the present invention, there is provided a washing machine having a memory function using memory means and having course start input means for selectively performing one of a plurality of courses in accordance with a program. The washing machine comprises key input means for selecting one of the plurality of courses and for determining a set of customized parameters for each course, the key input means having setting up setup conditions of the selected cycle course, the key input unit inputting whether to store the setup conditions; memory means for respectively storing a set of default parameters for each course and for respectively storing, in response to a user operation of the key input means, the customized parameters of each course; display means for displaying the parameters of each course, according to a user operation of the key input means; and a microcomputer for controlling the display of parameters stored in the memory means according to a user operation of the key input means. The key input means comprises a course control device for selecting the course; a plurality of parameter keys for determining the customized parameters according to an operation of the course control device; and a memory key for enabling an operation of the plurality of parameter keys and for enabling the storing in the memory means the customized parameters of each course.
It is to be understood that both the foregoing explanation and the following detailed description of the present invention are exemplary and illustrative and are intended to provide further explanation of the invention as claimed.
BRIEF DESCRIPTION OF THE DRAWINGSThe accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention. In the drawings:
Reference will now be made in detail to the preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings. Throughout the drawings, like elements are indicated using the same or similar reference designations where possible.
Referring to
The key input unit 100 includes a course control device 110 for inputting a selection of one among a plurality of courses and a parameter control panel 120 for inputting a selection of course parameters, based on the setting of the course control device, using a plurality of parameter keys. For example, by repeatedly pressing a parameter key, the selected function may shift through a predetermined set of parameters for adapting such parameters as washing time, water temperature, and the number of rinsing and dewatering cycles to be performed.
As in the case of the washing machine of the related art, the course control device 110 may be realized as a rotary switch (not shown) for selecting among a plurality of course settings. The selections of the course control device 110, however, include no separate setting for a “memory” course. In addition, the key input unit 100 of the present invention includes a memory key 130 for specifically saving parameters for any of the courses selectable via the course control device 110, as set by a user operation of the parameter control panel 120 or based on parameters read from the memory 200. Also, though not shown in the drawings, the course control device 110 operates in conjunction with a course execution key, such as a start/pause button, for initiating the execution of the selected course.
In the operation of the washing machine according to the present invention, the user may select one of a plurality of courses through the course control device 110 of the key input unit 100, to cause the default parameters of the selected course to be displayed. That is, the microcomputer 400 recognizes the selection and then reads from the memory 200 the default parameters corresponding to the selected course for display through the display 300. The selection of a memory function via the memory key 130, however, results in the microcomputer 400 clearing the displayed default parameters, whereupon the current parameters of the selected course are read from the memory 200 and displayed in their stead. The current parameters may then be set by the user or may have been previously set, taking the default parameters of the selected course as a reference.
To set the current parameters of a given course, the user operates the is parameter control panel 120 after pressing the memory key 130, to change the displayed parameters. Once a parameter selection is determined, and is visually confirmed through the display 300, the memory key 130 is pressed and held for a predetermined time period, say, three seconds, which saves in the memory 200 the thus changed parameters as displayed. This predetermined time is in contrast to a relatively short time for the above selection of the memory function. Also, the saving of the displayed parameters may be confirmed to the user through, for example, an audible signal such as a beep or a visual signal such as a change in the status of an illumination means.
Accordingly, the microcomputer 400 may recognize a customized set of parameters for each course of the course control device 110, each set of parameters being respectively stored in the memory 200 for selective access and recall through a subsequent user manipulation of the course control device followed by a pressing of the memory key 130. Thereafter, an operation of the start/pause button (not shown) initiates the course as displayed.
Referring to
In a step 110, the current parameters of the selected course, as stored in and read from the memory 200, are displayed on the display 300. Here, it should be appreciated is that the displayed parameters are either a set of default parameters or a set of parameters previously selected by the user. That is, if no customized parameters have been stored for the selected course, its default parameters are displayed.
It is then determined in a step S120 whether there is an input via the parameter control panel 120, which indicates the user's desire to change the displayed parameter settings of the selected course. If so, the displayed parameter settings are changed in a step S130 according to the key input. With the parameters thus set and displayed, it is determined in a step S140 whether there is an appropriate input via the memory key 130, which indicates the user's desire to save as displayed the parameter settings of the selected course. If so, the parameter settings of the selected course are saved in a step S150 as set and displayed in the steps S100-S130.
As described above, the steps of
Referring to
On the other hand, if it is determined in a step S220 that the memory key 130 has been pressed and held for a predetermined time, the displayed default conditions of the selected course are deleted in a step S230, whereby the current parameters of the selected course are read from the memory 200 and displayed on the display 300. Here, the current parameters are determined by the method of
Therefore, the present invention enables the user to set for execution the course parameters for each of a plurality of courses, as desired, in addition to executing each course according to its default parameters.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover such modifications and variations, provided they come within the scope of the appended claims and their equivalents.
