Description

  The present invention relates to a washing machine capable of selectively operating a preset automatic operation and an arbitrarily set manual operation.

  Conventionally, as a general washing machine, in addition to an automatic operation mode in which a rinsing process and a dehydrating process are automatically performed based on preset control contents, each process is manually operated to arbitrarily specify the process contents. It is configured to have a so-called manual operation mode that enables setting and desired operation. For example, FIG. 10 is an enlarged plan view showing an operation panel 1 provided in front of the main body of a washing machine with a drying function that is practically used. In recent years, the operation panel 1 can be controlled with fine washing. There are many push button type operation keys. Among them, “washing” key 2a, “rinse” key 2b, “dehydration” key 2c, “washing” key 2d, “washing” key 2e, “drying” key 2f, etc. are provided so that the process contents can be arbitrarily set. Permanent and well-used.

  For example, in the typical “washing” key 2a and “dehydration” key 2c, which are frequently used, the time to be set every time the pressing operation is performed is changed in units of 2 minutes and 1 minute, and the time corresponding to the setting contents is displayed. The information is sequentially displayed on the parts 3a and 3c. The “rinse” key 2b changes the number of times of rinsing and displays the number of times on the display unit 3b. Furthermore, the “washing” key 2d sets only a series of washing steps (from washing to dehydration and no drying step). Setting) or “washing / drying” key 2e is set to perform the drying process following the above-described washing process. In particular, each of the “washing”, “rinsing” and “dehydration” keys 2a, 2b and 2c Even the setting only requires the same pressing operation multiple times.

Therefore, when only the washing process is operated manually, only the “wash” key 2a is operated several times to set a desired time and the operation is started. However, there are households that routinely perform a series of processes based on the control contents arbitrarily set including the subsequent rinsing, dehydration, and drying processes, and in that case, more operations are required.
For this reason, there is a concern that a troublesome operation of pressing each of the operation keys 2a to 2f in the same manner is required and the setting operation becomes more difficult if the setting contents for each operation are not known in advance. Furthermore, in the above-described conventional configuration, even if the manual operation is arbitrarily set once, it is configured to return to the basic automatic operation control contents when the power is turned on / off (ON / OFF). A household that wants to use manual operation by setting had to be reset each time, and had the inconvenience of repeating the same useless operation.

On the other hand, instead of the push button type operation key as described above, for example, a slide type knob is provided, and a configuration including a display unit corresponding to the moving position is conceivable (for example, see Patent Document 1).
Japanese Examined Patent Publication No. 61-30283 (pages 2, 3 and 3)

  According to the knob configuration described above, it is not necessary to press the operation key the same number of times, and the user can set the desired stroke content relatively easily while viewing the display content. However, it is desirable that the automatic operation based on the preset control content can be easily switched with respect to the manual operation with the arbitrary setting. However, in the thing of such patent document 1, the exclusive knob for automatic driving | operations is provided, and it switches to automatic driving | operation irrespective of the said manual setting. For this reason, automatic operation is performed according to preset control contents regardless of the control contents indicated by the arbitrarily set knobs, and it is difficult for the user to determine which driving state the user is in. In addition, as described in this document, it seems that the use application is expanded by switching between manual operation and automatic operation by arbitrary setting according to the timing of the start switch operation, but the function by each knob operation is expanded. It is hard to use unless you are familiar with it.

  In order to solve the above problems, the present invention provides an operation knob corresponding to each stroke such as easy washing, and a manual operation portion in which the stroke content can be arbitrarily set by an operation displacement of the operation knob, It is an object of the present invention to provide a washing machine that can be switched to a part that is set for automatic operation and that can be expected to improve usability during manual operation.

  In order to achieve the above object, the washing machine of the present invention has an automatic operation mode in which a series of processes such as washing and rinsing automatically proceeds based on preset control contents, and the process contents are arbitrarily set. The operation panel can be selectively set to the manual operation mode that enables operation based on the control contents, and the operation panel is provided with operation knobs corresponding to the respective strokes, and the operation displacement of each operation knob is adjusted. The main feature is that it is provided with an arbitrary setting unit that is set according to switching and that can arbitrarily set the control content of the corresponding process to enable the manual operation and an automatic setting unit that enables the automatic operation. Is.

  According to the above means, it is possible to easily set the control content of each stroke by operating the operation knob along the display of the arbitrary setting section, and individually set the arbitrary setting section by the operation displacement of the operation knob corresponding to each stroke. Since the setting position can be easily viewed, the operation can be easily and reliably performed, and manual operation can be used on a daily basis without resetting the settings of the optional setting section. A washing machine that can be expected to improve can be provided.

  Hereinafter, an embodiment in which the washing machine of the present invention is applied to a washing machine with a drying function will be described with reference to FIGS. First, a description will be given based on an external perspective view showing a schematic configuration of the washing machine shown in FIG. 2. A main body 11 forming an outline of the washing machine includes a rectangular box-shaped outer box 12 and a top attached to the upper surface. And a cover 13. Among them, the outer box 12 is open at the upper and lower surfaces, and a bottomed cylindrical water tank 14 having an upper surface opened therein is provided via an elastic support mechanism 15. The water tank 14 can be drained through a drain valve 16 at the bottom, and air, a lap and an air tube 17 are connected in the vicinity of the bottom, and communicated with a water level sensor 18 comprising a pressure switch at the upper end.

  Inside the water tank 14 as described above, a washing tub 19 serving also as a dewatering tub is provided so as to be rotatable around a vertical axis. The washing tub 19 also has a bottomed cylindrical shape with an upper surface opened as in the case of the water tub 14. However, the peripheral wall portion includes a plurality of through holes 19a that function as water holes and vent holes. In addition, a large-diameter stirring body 20 is provided at the inner bottom portion of the washing tub 19 so as to be able to rotate in the forward and reverse directions, and a driving mechanism 21 for rotating the washing tub 19 and the stirring body 20 is provided at the outer bottom portion. The drive mechanism 21 includes, for example, an outer rotor type motor and a clutch that selectively transmits the rotation of the motor to the washing tub 19 and the stirring body 20. Accordingly, operation control is basically performed through this drive mechanism 21 so that only the stirring body 20 is rotated in the easy washing process, and the washing tub 19 is rotated together with the stirring body 20 in the dehydration and drying processes.

  On the other hand, the construction of the top cover 13 will be described. An inlet for loading and unloading laundry (not shown) is formed in the substantially central portion of the top cover 13, and a double-folded laundry lid 22 is rotatably attached to open and close the opening. It has been. In addition, an operation box 23 is formed at the rear portion of the top cover 13, and a not-shown hot air generating unit, a water supply valve, and the like are disposed therein, as well as a switching mechanism described later. A hot air duct 24 is connected to the hot air generating unit, and a water supply duct 25 is connected to the water supply valve so that hot air and washing water can be supplied into the water tub 14 and the washing tub 19, respectively. .

  An operation panel 26 is formed on the upper surface of the operation box 23, and the operation panel 26 is provided with a plurality of dial type operation knobs. Hereinafter, this operation knob will be described with reference to an enlarged plan view of the operation panel 26 shown in FIG. 1. As a dial type operation knob in the present embodiment, roughly, a reserved time for washing operation is set from the left side of the figure. "Reservation" knob 27, and then operation knob 28 corresponding to each process such as "washing, rinsing, dehydration, drying", specifically "washing" knob 28a for setting the washing time, setting the number of times of rinsing A “rinse” knob 28b for setting a dehydrating time, a “dehydrating” knob 28c for setting a dehydrating time, a “drying” knob 28d for setting a drying time, and an operation knob 29 for setting a course are sequentially arranged. In addition, a “start” key 30 and a “power” key 31 are provided as push button operation keys, and these have a switch function mainly for switching between so-called ON / OFF operations.

  More specifically, the "washing" knob 28a has a time interval gradually increased from the original 2 (minute) interval to a maximum of 80 (minute) around the periphery of the rotating pointer 34. This area is printed and displayed, and an area in which this time can be set arbitrarily is formed as the optional setting section 32a, and manual operation is possible with the control content corresponding to this setting. On the other hand, an automatic setting section 33a described as “automatic” that can be turned on and displayed at a portion corresponding to time 0 (minutes) (not shown) is formed. This is because the automatic operation can be performed based on the control contents set in advance by setting the pointer 34 of the “wash” knob 28a, which is the operation knob, to this “automatic” position. The details will be described later.

  Such a configuration is similarly applied to the other operation knobs 28, that is, an arbitrary setting unit 32b and an automatic setting unit 33b that can set the number of times of rinsing up to 1 to 3 in the "rinse" knob 28b. In the “dehydration” knob 28c, an arbitrary setting section 32c and an automatic setting section 33c that can set the time up to a maximum of 10 minutes in 1 (minute) intervals, and in the “drying” knob 28d that sets the drying time, 20 (minute) intervals. Thus, an optional setting unit 32d and an automatic setting unit 33d that can arbitrarily set the drying time up to 180 (min) are formed.

  FIG. 3 illustrates a switching mechanism corresponding to the operation knob. FIG. 3A is an exploded perspective view of the operation panel 26 and the printed wiring board 35 disposed on the inner surface side thereof. The printed wiring board 35 is provided with switching mechanisms 36 to 41 corresponding to each of the plurality of operation knobs described above. For example, the "washing" knob 28a will be described with an operation shaft 37a connected thereto. The contact switching unit 37b switches the contact circuit in accordance with the rotation of the operation shaft 37a (movable contact 42a). The contact switching unit 37b contacts and separates from the movable contact 42a as shown in FIG. A circuit pattern for the fixed contact 42b is formed, and the microcomputer 43 to which a continuity signal based on the closed circuit of the contact is input is used in accordance with a desired process content. And operation control is configured to be made.

  Note that the switching mechanisms 38 to 40 corresponding to at least the “rinse” knob 28b to the “dry” knob 28d of the switching mechanisms other than the above also have the same operation shaft and contact switcher (not indicated) as described above. However, the automatic setting unit 33 that enables automatic operation and the optional setting unit 32 that enables manual operation can be easily switched by operating the operation knobs 28 corresponding to the respective washing and drying steps. In addition to being able to set, it is possible to manually set the desired control content of the desired stroke substantially simultaneously with the setting of the arbitrary setting unit 32.

  Next, with respect to the operation of the washing machine having the above-described configuration, particularly when the operation contents such as easy washing are set by the operation knob 28, enlarged views of main parts showing different examples of use are particularly shown in FIGS. The description will be given with reference. First, FIG. 4A shows a state set to perform automatic operation. That is, in this embodiment, it is automatically operated up to a drying process following a washing process such as washing, rinsing, dehydration, etc., and the capacity of the laundry is detected as generally known at the start of the operation, and according to this The water supply amount is controlled by the water level sensor 18, and the washing process based on the stirring operation by the stirring body 20 is executed for a predetermined time.

  Thereafter, the rinsing process and the dehydrating process are automatically performed, and in this case, the rinsing process and the dehydrating process are controlled based on a preset time and number of times, and then the process proceeds to the drying process. In this drying process, hot air from a hot air generating unit (not shown) is supplied from the hot air duct 24 into the washing tub 19 and is discharged after contributing to the drying of the laundry inside, and then the washing lid 22 of the main body 11 and the like. It is discharged out of the machine through a gap such as an opening on the lower surface, and a drying operation is performed by means of exhausting outside while supplying so-called hot air, and then an optimal drying time is executed via the drying detection means, End automatic operation.

  In FIG. 4A showing the automatic operation mode as described above, when the “power” key 31 is in the “ON” (ON) state, the knobs 28 a to 28 d of each stroke are automatically set by the respective hands 34. Pointing to the parts 33a to 33d, the display part "automatic" is lit up and the setting state can be easily identified. FIG. 4B shows a state in which the automatic operation mode is switched to perform, for example, manual operation only in the dehydration process.

  That is, the “dehydration” knob 28c is dialed to set the pointer 34 from the automatic setting section 33c to the 5 (minute) display of the arbitrary setting section 32c. As a result, the automatic setting section 33c is canceled and only the process newly set manually is effective, so the automatic operation from washing to drying is canceled, and the lighting display of each of the automatic setting sections 33a to 33d is All are turned off. Then, by depressing the “start” key 30, only the dehydration process based on the arbitrary setting is operated in this case. In this dehydration process, first, the drain valve 16 is opened, and then the washing tub 19 rotates at a high speed with the agitator 20, and the centrifugal dehydration of the laundry is performed for 5 minutes and is terminated. The displacement of the “dehydration” knob 28c and the setting positions of the pointer 34 are maintained as they are, so that the setting contents can be confirmed at any time and can be used repeatedly.

  As described above, the time setting operation in the arbitrary setting unit 32c for performing the manual operation can be performed by simply dialing the “dehydration” knob 28c in one direction in accordance with the time display, and all automatic setting is performed. Since the parts 33a to 33d are turned off, switching to manual operation can be easily confirmed. This is not limited to the above-described dehydration process, and can be performed in the same manner when performing an independent operation in another process.

  Incidentally, FIG. 5 showing another example of use is a diagram corresponding to FIG. 4, and FIG. 5 (a) shows an automatic operation mode in which each pointer 34 is lit and displayed pointing to the automatic setting units 33a to 33d. . From this state, as shown in FIG. 5B, only the “wash” knob 28a is dialed, and for example, the pointer 34 is set to “60” (minutes) display of the arbitrary setting section 32a. Then, by pressing the “start” key 30, the manual operation of only the washing process is executed. In this washing process, the washing operation by the agitator 20 is executed for the set time (60 minutes) based on the water level determined by detecting the volume of the laundry, and is finished.

  However, special control contents are incorporated and set in advance especially in the washing process. That is, in the time setting of the optional setting unit 32a, when the normal washing time is set to 15 (minutes), a normal washing operation with a standard water flow is performed. If the time is set to 20 (minutes) or longer in this embodiment due to the possibility that the laundry may be damaged if the operation is continued, the rest period (OFF) of the stirring body 20 is lengthened and the operation time is increased. (ON) is a shortened washing water flow, and is converted to a water flow mode suitable for so-called soaking.

  Therefore, when set to “60” (minutes), for example, the stirrer 20 is programmed to perform a washing operation by a stirring operation by 30 minutes OFF and 1 minute ON, or in the latter half by a standard water flow washing operation. You may do it. Further, in the case of normal soaking and washing, the washing effect is enhanced by soaking in a high-concentration detergent solution. Therefore, the washing time is set to “60” (minutes), followed by rinsing and dehydration. In this case, manual operation may be performed by setting appropriate washing conditions such as setting a large number of times of rinsing in consideration of the generation of a large amount of detergent and a large amount of detergent.

  In addition, the usage example is not limited to the above-described single operation, and for example, it is possible to perform manual operation by selecting and operating a plurality of strokes, and arbitrarily change all stroke contents from washing to drying. If set, each manual operation can be executed continuously under the desired control content. Note that, in the arbitrarily set drying process, the drying operation is performed only for a desired set time, and the process is terminated regardless of the drying detection.

  In the case of manual operation based on such an arbitrary setting, all the automatic setting units 33a to 33d are turned off, and it is easy to be in the manual operation mode from the position of the pointer 34 of each operation knob 28a to 28d. In addition, since it is maintained regardless of whether the power is on or off, manual operation in which a washing mode unique to the home in consideration of the washing condition and environment can be used on a daily basis without re-setting operation. When converting from the manual operation mode to the automatic operation mode, all the operation knobs 28 are set to the automatic setting unit 33 so that they are lit and displayed. The operation mode can be easily identified, and the displacement of the operation knob 28 and the direction of the pointer 34 can be easily visually recognized.

According to the above embodiment, the following effects can be obtained.
By dialing the operation knob 28 corresponding to a plurality of strokes, the automatic setting unit 33 or the arbitrary setting unit 32 can be easily switched, and the switching selection between the automatic operation mode and the manual operation mode can be easily and reliably performed. At the same time as the switching setting to the arbitrary setting unit 32, the specific control content of the process can be set, the displacement direction of the operation dial 28 itself and the pointing direction of the pointer 34 can be easily visually confirmed, and each operation The knob 28 can be used in practice without requiring special functional knowledge, such as a single simple dial operation. Therefore, it is particularly easy to use compared to the case where a single operation key is pressed many times, such as a conventional push button type operation key, or the setting contents displayed each time the operation key is viewed. This is advantageous in that it is improved and misuse is eliminated.

  In addition, in the present embodiment, since the display means by turning on and off the automatic setting unit 33 is adopted, it is possible to discriminate more clearly. In addition, the manual operation mode based on the control content set as desired in the optional setting unit 32 can be used repeatedly without the need for re-setting, and in particular, the washing operation can be performed in accordance with home-specific washing conditions. It has the advantage that it can be easily used on a daily basis.

  It should be noted that the present invention is not limited to the above-described embodiments, and various specific configurations can be developed. For example, as a configuration of the switching mechanisms 37 to 40 provided corresponding to the operation knob 28, a well-known encoder is used for fine circuit control. A so-called rotary type switching mechanism is advantageous in that the printed wiring board 35 can be configured in a compact manner so that it can be easily performed. Alternatively, other switch functions may be added to the operation panel 26 to enhance the operation functions, and various display means corresponding to the arbitrary setting unit 32 and the automatic setting unit 33 may be considered. 6 to 9 show first to fourth modified examples of the above embodiment, the same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. explain.

(First modification)
First, FIG. 6 is a diagram corresponding to FIG. 4 showing a first modification, which can perform automatic driving with different course settings without requiring a plurality of picking operations from the state of a normal automatic driving mode set in advance. For this reason, one switching knob 44 for selecting a stroke, which will be described later, is provided. That is, the switching knob 44 is configured to include, for example, three course setting units, a “washing” course 45a, a “washing” course 45b, and a “drying” course 45c.

  The “laundry” course 45a is a course operation that includes the steps from washing, rinsing, and dehydration as described above. In other words, an automatic operation in which only the drying step is canceled is performed. When the “washing and drying” course 45b is set, this is a course for performing all automatic operations up to the drying process following the “washing” course, and when the “drying” course 45c is set, only the drying process is automatically performed. It is intended to drive.

  6 will be described. FIG. 6A shows the course setting in which the switch knob 44 indicates the “wash and dry” course 45b, and all the automatic setting sections 33 are lit and displayed. Is shown. FIG. 4B shows a state in which the switch knob 44 is dialed to the left and set to the “washing” course 45a from this state. In this case, as described above, the course setting from the washing to the dehydration is automatically operated and the drying process is canceled, so the washing, rinsing, and dehydration automatic setting units 33a, 33b, and 33c are executed. Only the automatic setting unit 33d for the drying process that is kept on and is not operated is turned off.

  Therefore, according to such a configuration, it is possible to switch the course operation in which the necessary stroke or the unnecessary stroke is selected and set in the automatic operation only by the operation of one switching knob 44, and the course equivalent to the above-described mode. Compared with the case where the setting is performed by the arbitrary setting sections 32a, 32b, and 32c, it can be dealt with by a simple operation. However, when the washing time, the number of times of rinsing, the dehydration time, etc. are uniquely set and these are continuously operated, it goes without saying that the setting by the desired arbitrary setting unit 32 is required as described in the above embodiment. Yes. In addition to the above, it is needless to say that the same operational effects as the above-described embodiments such as improvement in operability can be expected.

(Second modification)
Next, FIG. 7 is a view corresponding to FIG. 4 showing a second modified example. In the embodiment, each of the operation knobs 28a to 28d is provided with a cancel setting unit 46. By setting the knob 28 in accordance with the display “OFF”, the operation in which the corresponding stroke is canceled can be performed. Therefore, in the case where the automatic operation of the “laundry” course is set in the same manner as described above from the automatic operation mode in which the automatic setting units 33 for all the strokes shown in FIG. Only the “drying” knob 28d in the drying process to be canceled is dialed to set the pointer 34 to the corresponding “OFF” position.

  Accordingly, the automatic setting sections 33a to 33c corresponding to the respective steps from the washing to the dehydration course of the “washing” course are kept lit and displayed, and only the “automatic” display of the automatic setting section 33d for the drying process is turned off. Accordingly, automatic operation is performed only for the strokes that are lit and displayed. In such an embodiment, the desired cancellation setting unit 46a to 46d can be set by the dial operation of the operation dial 28 for setting the strokes to be canceled at any time in the automatic driving mode. It can be easily adjusted to 46d, and has an advantage that it is effective when the number of strokes to be canceled is small and the operability is good.

(Third Modification)
FIG. 8 is a view corresponding to FIG. 1 showing a third modified example, which is a dial-type operation knob 47 of the same kind as in the above embodiment, and does not require the pointer 34 as described above. In addition, it is not necessary to form the optional setting unit 32 and the automatic setting unit 33 around it by printing or the like, and instead, the function of the arbitrary setting unit 32 and the automatic setting unit 33 is also used instead. The segment LED display section 48 is provided in the vicinity of the upper portion of the operation knob 47.

  Thus, in the LED display 48, the case of functioning as an optional setting unit will be described. When the knobs 47a to 47d from washing to drying are selected, arbitrary times and times are displayed in the figure. This indicates that the content is arbitrarily set and is in a so-called manual operation mode. More specifically, the arbitrary setting operation will be described. First, when the “washing” knob 47a is dialed, a predetermined switching of the LED display section 48 is performed via a switching mechanism (not shown) (corresponding to the switching mechanism 37 shown in FIG. 3). If the time is sequentially displayed on the part and the operation is stopped when a desired time (for example, 20 minutes) is displayed, the setting of the washing time is completed.

  In the “rinse” knob 47b, the number of times of rinsing (for example, two times) is set by the same dial operation as described above. Similarly, in the “dehydrated” knob 47c, a dehydration time (for example, 8 minutes) is set, and “dry” In the knob 47d, a drying time (for example, 90 minutes) is set. Accordingly, by subsequently pressing the “start” key 30, the manual operation based on the arbitrarily set time and number of times is continuously executed from the washing process to the drying process. In this embodiment, a numerical value corresponding to the arbitrary setting unit is displayed on the LED display unit 48. However, when the LED display unit 48 functions as an automatic setting unit for automatic operation, the LED display unit can be operated by a similar dial operation. For example, the code “A” is selectively displayed instead of “automatic” in the above-described embodiment, so that the automatic operation mode can be easily converted and easily identified.

As described above, although the display means functioning as an automatic setting unit or an arbitrary setting unit is different from the above-described embodiment, it can be effectively used without repeated setting of simple operation by dial operation and manual operation setting content. In particular, the same effects as those of the above-described embodiment can be expected.
The operation knob 47 has a disk shape that does not require the pointer 34. However, the present invention is not limited to this, and needless to say, it may be the same as that of the above embodiment. A dial-type “course” key 49 is provided around the “start” key 30.

(Fourth modification)
FIG. 9 is a view corresponding to FIG. 1 showing a fourth modification, which can be said to have a configuration in which setting content display means is different from that of the third modification. That is, display "automatic" corresponding to the automatic setting unit 50 (50a to 50d) is formed on the upper part corresponding to the operation knob 47 (47a to 47d), respectively, and the arbitrary setting unit 51 (51a to 51d) is adjacent to this. The numerical values are formed so as to be backlit when selected and set.

  Therefore, when performing automatic operation set in advance, in order to set all of the automatic setting units 50a to 50d to “automatic” display, dials are operated on the knobs 47a to 47d to form a circuit by a switching mechanism (not shown). The “automatic” display by backlight can be selected and set. On the other hand, when performing manual operation, for example, if only washing operation is performed, a desired washing time is set by dialing the “wash” knob 47a and selecting “10 minutes” displayed on the backlight, for example. Thereafter, when the “start” key 30 is pressed, only the washing process is executed under the water level control according to the laundry volume as described above, and the same effects as the above-described embodiment can be obtained. It is.

  The present invention is not limited to the embodiment described above and shown in the drawings. For example, the present invention is not limited to a washing machine with a drying function, and in summary, a plurality of steps are automatically performed with preset control contents. It can be widely adopted as long as it is a washing machine that allows manual operation by arbitrarily setting the desired process to the desired control content and the operation knob is not limited to the dial type, and the operation displacement of the operation knob It is only necessary to selectively set the automatic setting unit and the task setting unit according to the above, and various specific changes can be made without departing from the scope of the present invention.
