Description

  The present invention relates to a washing / drying machine, and more particularly to a washing / drying machine capable of easily performing a user's favorite operation.

  For example, Japanese Patent No. 3,163,194 is known as a conventional technique for simplifying a user's preferred driving.

  This prior art discloses a memory course that stores and executes the strength, time, etc. of each of water supply, washing, rinsing, and dehydration processes set by the customer.

  In addition, this prior art discloses that two memory courses are provided and that the memory course is continuously set automatically after the operation of the memory course is completed.

Japanese Patent No. 3,163,194

  However, the above prior art has only one operation mode, and presupposes one operation mode and stores the strength, time, etc. of each of the water supply, washing, rinsing and dehydration processes. is there.

  Therefore, no consideration is given to a washing / drying machine having a plurality of operation modes.

  Then, an object of this invention is to provide the washing-drying machine which can perform a user's favorite driving | operation easily.

  In order to achieve the above-mentioned object, the present invention provides a washing / drying machine comprising: means for storing one of the operation modes and one of the plurality of courses; a button for reading the stored operation mode and course; When the button is operated, the stored operation mode and course are displayed.

  ADVANTAGE OF THE INVENTION According to this invention, the driving | operation according to a user's liking can be performed easily.

  In this embodiment, the contents of the memory course set by the user according to his / her preference are stored at the same time as the start button is pressed. From the next time, the memory course can be used repeatedly without resetting. Furthermore, at least the number of the above-mentioned memory courses is provided so as to be able to store all the driving favourites that can be normally selected by the user.

  FIG. 1 is a diagram of an operation panel of the washing / drying machine according to the present embodiment.

  A start button 9c for starting operation is disposed at the center of the operation panel 9, and a detail setting unit 9b in which buttons for performing various detailed settings are arranged on the left side around the start button 9c. On the right side of the start button 9c, a course selection unit 9a for specifying an operation mode, a course, and the like is collected. A memory course button 16 for selecting the memory courses 1 to 3 is disposed above the start button 9c. With this arrangement, when using the memory course, the user presses the memory course button at the upper center, reads out the operation contents registered in advance, and then the start button 9c immediately below it. By pressing, it is possible to easily execute the course of the operation content set in advance. Further, when a course is simply selected from the set program, it can be executed by pressing the right operation mode button, selecting a desired course, and then pressing the start button 9c adjacent to the left. Thus, by arranging the button group for each function centering on the start button, a user-friendly button layout can be provided to the user.

  Next, a method for registering favorite contents in the memory course 1 will be described with reference to FIG.

  FIG. 1 shows a state in which the memory course 1 is first selected by pressing the memory button, and then the standard course for the washing mode is selected by the lower right operation mode button. In FIG. 1, in addition to the standard course for the washing mode, a course that can be selected according to the quality of clothing such as soft, dry, and blanket is provided. In the state where the memory course 1 is set, by pressing the “washing”, “washing”, and “drying” mode buttons at the lower right of the panel, the operation course of each operation mode can be selected. At this time, the mode button lights to indicate to the user that each mode button is selected. The lighting colors at this time may all be the same, but the user's recognition rate becomes higher by dividing the color for each mode. After the mode is selected, the “Water” button, “Washing” button, “Rinse” button, “Dehydration” button, “Drying” button, “Hot water” button, “ The details of the operation can be selected according to the user's preference by the “hot high cleaning” button. By pressing each of the selectable contents, the amount of water during operation is displayed for the “Water” button, the washing time for the “Rinse” button, the rinsing method and number of times for the “Rinse” button, and the dehydration time for the “Dehydration” button. In the "Dry" button, the drying time and automatic operation, in the "Hot water" button, the washing process in which the bath water is absorbed, in the "Hot high wash" button, to increase the detergency at the beginning of washing The presence or absence of the hot air stroke can be selected.

  By pressing the “start” button after setting each content, the content of the memory course 1 is stored. In the conventional technique, when selection and drying are performed in another driving course after this, it is impossible to drive the same course unless the above operations are repeated. However, according to the present invention, since the memory course can be memorized in detail by starting with the memory course selected, even after driving a course different from the course stored once, the memory course Since operation preparation can be completed only by pushing a button, a user's operativity improves significantly.

  Figure 2 shows the purpose of preventing substances that cause allergies such as pollen on clothes by increasing the number of times of rinsing and drying outside in order to reduce the amount of detergent remaining in the clothes during the washing course in Memory Course 2. The case where “drying” is set to be performed in an automatic course is shown.

  FIG. 3 shows a case in which a 30-minute drying operation is set in order to finish-dry the clothes that have been air-dried in the memory course 3.

  In the present embodiment, an example is shown in which the operation contents in the washing mode, the washing / drying mode, and the drying mode are stored in each memory course. However, in actual use, the washing mode is stored in all the memory courses according to the user's preference. It is also possible.

  By registering courses with different operation modes in each memory course in this way, it is a case of driving courses with different modes frequently, such as daily washing contents and separate washing. However, it is possible to easily call a favorite course by simply pressing the memory course button several times.

  FIG. 4 is a block diagram of a control circuit of the washing / drying machine in this embodiment.

  In FIG. 4, when an embedded course other than the memory course is designated, the microcomputer 20 drives the solenoid output circuit 23, the output circuit 24, etc. according to the control sequence of each course stored in advance, and displays it. The circuit 25 is driven to display the state value and the like at that time on the operation panel 9. The power is supplied from the power circuit 26.

  Further, when the memory courses 1 to 3 are designated by the operation switches 21 of the operation panel 9 and the contents are set by “water amount”, “wash” and other switches, the microcomputer 20 interprets the contents. The data is temporarily stored in the RAM 20a and displayed on the display circuit 25, and the contents of the RAM 20a are stored in the memory 22 in response to a start command from the start button. Thereafter, the operation of each unit is sequentially executed according to the contents of the RAM 20a. Each time the contents of the memory course by the operation switches 21 are set, the contents can be stored directly in the memory 22 and the RAM 20a can be omitted.

  The memory 22 uses a non-volatile memory such as EEPROM, for example, so that the stored contents are retained even after the power is turned off. Further, the contents of the memory course executed before the power shut-off are stored in a predetermined area of the memory 22, and after the power is turned on again, the contents of the memory courses 1 to 3 designated by the memory course button are read. So that it can be re-executed at the same time.

  For example, when executing the memory course 1, when water supply is started and the water level reaches a predetermined cloth amount sensing water level, the water supply is temporarily stopped and stirred for about 30 seconds to perform cloth amount sensing. Detect quantity and quality. The microcomputer 20 determines that the water level is appropriate, for example, “medium” by the cloth amount sensing. However, since the “water amount” is designated as “high” by the memory course 1, the “high” water level is set.

  Next, when the water is supplied to the “high” water level, cloth quality sensing is performed to determine the time, frequency, etc. of “washing”, “rinsing”, and “dehydration”. Normally, this determined value is adopted as the content of the standard course, but since detailed settings of “washing” and “dehydration” are designated by the memory course 1, washing is executed at a designated time. When this driving is completed, the contents of the course setting are held in the memory course 1, and the My Coins are set in a driving standby state (initial state).

  When “memory course 1” is set next time, the contents of the memory course 1 stored in the memory 22 are displayed and automatically re-executed in response to the start command. The same operation is performed when “memory course 2” as shown in FIG. 2 is set. That is, the contents of the user-specified values of “washing” for 15 minutes and “rinsing” for 3 times of water injection are stored in the memory 22 immediately after the start, and even after the operation, the Mycoin 20 displays “Memory Course 2” for driving. It becomes a standby state (initial state). From the next time, when “memory course 2” is set, the contents of the memory course 2 stored in the memory 22 are displayed and automatically re-executed in response to the start command.

  FIG. 5 is a flowchart of the operation in this embodiment.

  When the embedded program is designated by the course button, this is executed in the same manner as in the conventional apparatus. When a memory course is designated, the contents are set and displayed according to the numbers 1 to 3, and the contents are written in the memory 22 when the start button is pressed. Since the contents of the memory 22 are returned to the memory course specifying step, the memory course stored in the memory 22 is automatically set and displayed next.

  As described above, according to this embodiment, since the button for reading the operation mode itself is provided, it is possible to easily execute the operation mode according to the user's preference.

  The memory has at least the number of memory courses equal to or greater than the operation mode, and at least one memory course can be stored for each operation mode. As a result, the user can store his / her favorite driving content for each driving mode, and can select a driving course to be frequently used without performing troublesome button operations.

  Further, according to the present embodiment, the contents of the memory course are stored at the same time as the execution start command (start) of the washing machine, so that the case where the power is shut off after the execution or before the buzzer sound to notify the completion or the water supply It is possible to solve the problem that the set memory course is not stored when the power supply is shut off due to an abnormality or an abnormal drainage. In addition, since the memory program is not set at the end of execution of the memory program as in the conventional device, the salesperson of the washing machine immediately sets the user's favorite program on the spot at the request of the user can do. Similarly, the memory course can be displayed and explained immediately.

  Further, since the contents of the set memory course are stored in the nonvolatile memory, they can be reused from the next time. In addition, since the memory course is automatically set and displayed after the operation of the memory course is completed or when the power is turned on again after the power is turned off, the memory course can be continuously reused with one touch. In addition, since a plurality of memory courses are provided, a course for baby underwear, a course for which dehydration operation is not desired, and the like can be provided in addition to a course for underwear and daily wear. A memory course can be set for each process such as washing, washing and drying.
