Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a washing machine that executes each process such as washing, rinsing, and dehydration in a set operation mode, and in particular, the method for setting the operation mode has been improved. The present invention relates to an operation mode setting device for a washing machine.

[Technical Background of the Invention] Conventionally, this washing machine, for example, a fully automatic washing machine, is equipped with an operation control circuit consisting of a microcomputer, and a plurality of operation modes are selectively set in the operation control circuit, and the operation mode is An example of the operation mode mentioned above is a "fully automatic" mode in which the washing process, rinsing process, and dehydration process are performed continuously.
There are two operating modes, one for washing and one for rinsing.
There is a ``wash/rinse'' operation mode, a ``rinse/spin'' operation mode that performs the rinsing process and the dehydration process, a ``wash only'' operation mode that performs only the washing process, and a ``Suzuginoro'' that performs only the rinse process. driving mode,
There is a "dehydration only" operation mode in which only the dehydration process is performed. In order to set these multiple operation modes in the operation control circuit, in a conventional fully automatic washing machine, as shown in Fig. A display section 2 is provided to display the set time for each stroke and the set time for the dehydration stroke, and a washing stroke setting switch 3 is provided for inputting and setting each stroke to the operation control circuit. The configuration is such that a zuzugi stroke setting switch 4 and a dewatering stroke setting switch 5 are provided, respectively. Then,
Conventionally, when setting the operation mode to, for example, "fully automatic" as the operation mode, first, by operating the washing stroke setting switch 3 an appropriate number of times, the washing stroke is set, and the washing stroke is set depending on the number of operations. Set the culm washing operation execution time (for example, "15 minutes" for one operation, "10 minutes" for two operations, and "5 minutes" for three operations), and then operate the Suzuki stroke setting switch 4. By setting the rinsing process, and further operating the dehydration process setting switch 5 an appropriate number of times, the dehydration process can be set, and the dehydration operation execution time of the dehydration process according to the number of operations (one operation is 1 minute). ", "3 minutes" for the same two concave times, "5 minutes" for the same three times). In this way, the "fully automatic" operation mode is set, in which the washing process according to the set execution time, the rinsing process a set number of times, and the dehydration process according to the set number of times are executed according to their temporal order. To set other operation modes, similarly, any one of the switches 3, 4, and 5 is operated the same number of times as appropriate. After setting the operation mode, the start switch 6 is operated to cause the operation control circuit to execute the operation mode.

[Problems with the Background Art] However, in the conventional case, all strokes included in the operation mode to be set must be set,
For this reason, it is necessary to understand the stroke contents for each of multiple operation modes, and in some cases it may be necessary to confirm the stroke contents of the operation mode one by one. The actual situation was that the operating procedures were difficult to understand as they were difficult to understand.

[First aspect of the invention]] An object of the present invention is to provide an operation mode setting device for a washing machine that allows easy setting and operation of selectively setting an operation mode.

[Summary of the Invention゛] The present invention provides a display section that shows each row of washing, rinsing, and dewatering in accordance with a predetermined chronological order, and displays a starting point earlier in the chronological order and a starting point from this point onward in the chronological order. A start point designation member and an end point designation member are provided to arbitrarily designate the subsequent end point, respectively, and the operation is controlled using the operation mode as a journey including the section from the start point to the end point designated by the start point designation member and the end point designation member. This is set in the circuit, so that it is only necessary to specify the start stroke and end stroke of the drive mode to be set as the operation details for setting the drive mode.

Reference numeral 15 denotes a well-known water level detection device that detects the water level in a rotating tank (not shown) for pre-washing water and provides a detection signal to the operation control circuit 11. 16 is a water supply valve that supplies water to the rotating tank; 17
Reference numeral 18 indicates a motor that selectively drives a rotating tank and an agitator (not shown), and 18 indicates a drain valve 6 which discharges water from the rotating tank.These water supply valves 16. Motor 17 and drain valve 18
are driven by drive signals given from the operation control circuit 11 via drive circuits 19, 20 and 21, respectively. Next, FIG. 1 shows an operation panel 22, in which 23 is a display section, which includes a process display section 24 for showing each process of washing, rinsing, and dehydration, and a process display section 24 for showing each process of washing, rinsing, and dehydration Time display section 25 that displays the operation execution time of each row culm of dewatering

8 and 29, and the process display section 24 shows "wash",
The words "rinsing" and "dehydration" are arranged in accordance with the chronological order of each process, for example, from left to right. Further, the marker 28 represents the end point of the washing process (or the starting point of the rinsing process), and the marker 29 represents the ending point of the rinsing process (or the starting point of the dehydration process).

Reference numeral 30 denotes a sliding hole in the operation panel 22, which is formed below the display section 23 so as to extend in the left-right direction.A starting point designation member 31 and an end point designation member 32 are installed in the sliding hole 30, respectively. It is arranged to be slidable between the corresponding positions of the light emitting diode 27 and the markers 28, 29, and after sliding, the re-designating member 31, 32 is held at each corresponding position. There is. These re-designation members 31 and 32 are connected to the previously described operating device 14 together with a setting signal output circuit (not shown).
The setting signal output circuit provides a stroke start point setting signal and an end point setting signal to the operation control circuit 11 according to the sliding position of each specified portion 31 and 32. still,

As shown in Figure 3, the operating modes set in 1 can be roughly divided into "fully automatic" mode, which executes washing, rinsing, and dehydration steps in that order, and "washing" mode, which executes only the washing step. There are two operating modes: 1), a ``wash/rinse'' mode that executes each washing and dehydration process in sequence, and an ``rinsing/spindle'' operation mode that executes each rinsing and dehydration process in sequence, and a dehydration mode. There is a "dehydration only" mode of operation in which only the process is executed, and a "rinsing only" mode in which only the rinsing process is executed. The washing process consists of a water supply operation and a washing operation, and the execution time of this washing operation is set to either "15 minutes J, rlo minutes" or "5 minutes". Further, the rinsing process consists of a drainage operation, a dehydration operation, a water supply operation, and a perch operation. Furthermore, the dehydration process consists of a drainage operation and a dehydration operation, and the execution time of the dehydration operation is
5 minutes,” 3 minutes, and 1 minute.

As shown in FIG. 4(a), the starting point designation member 31

From the starting point "washing 10 minutes" specified by
In this case, the operation control circuit assumes that the operation mode is ``fully automatic'', and the operation mode is ``full automatic''. 11 is specified. In this case, the light emitting diode 27 corresponding to the stroke in the above section is lit (the lighting state is indicated by diagonal lines), and the stroke in the -J1 section is displayed to be distinguished from the stroke in other sections. Then, start switch 3
4, the operation control circuit 11 turns on the water supply valve 16.4 to execute the set operation mode. The motor 17 and the drain valve 18 are driven and controlled as appropriate, and the light emitting diode 2
7 blinks in sequence corresponding to the process being executed. Next, as shown in FIG. 4(b), use the starting point specifying member 31 to specify "wash 10 minutes," and use the end point specifying member 32 to specify the marker 28 between "wash" and "rinse." , the process included in the section from the start point to the end point (washing process with a washing operation execution time of 10 minutes) is set as the operation mode. In this case, the operation mode "wash only" is the operation control circuit 11.
, and the stroke included in that section is displayed by lighting the light emitting diode 27 to distinguish it from the strokes in other sections. Similarly, FIG. 4(c) shows the case where the "wash/rinse" operation mode is set, and FIG. 4(d) shows the case where the "rinse/spin" operation mode is set. FIG. 4(e) shows the case where the operating mode is set to "dehydration only", and FIG. 4(f) shows the case where the operating mode is set to "rinsing only". According to this embodiment, when setting the driving mode, the operation is simply to specify the stroke corresponding to the start point and the stroke corresponding to the end point using the designated parts 31 and 32. Moreover, in this case, the display section 23 displays each process of washing, rinsing, and dehydration according to the chronological order, so the start point specifying member 31 and the end point specifying section O are arranged according to the display section 23. 32 operations can be performed, and there is no need to know the process details of the operation mode in advance, and overall, the operation for setting the operation mode can be performed extremely easily.

In particular, in the case of this embodiment, since the start point designation member 31 and the end point designation member 32 are held at positions corresponding to each stroke, when setting the operation mode next time, if there is no change in the operation mode, each Since the previously set operation mode is set in the operation control circuit 11 based on the setting signals corresponding to the positions of the designated part shrines 31 and 32, there is no need to repeat the operation, making it convenient. Furthermore, according to this embodiment, the light emitting diode 27 displays the stroke included in the specified section separately from the stroke in other sections, so that it is possible to check the contents of the stroke of the driving mode to be set. Therefore, incorrect settings can be avoided.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the stroke display section 24 is replaced with the sliding hole section 30 of the first embodiment.
A first sliding hole 35 is formed from "washing" to "marker 29", and a second sliding hole 36 is formed from marker 28 to "dewatering", and the first sliding hole 35 is formed from "washing" to "marker 29".
The starting point designation part 4A31 is arranged at the second sliding hole part 36.
The configuration is such that the end point designation member 32 is disposed at. In this case, the size relationship is such that the end point designation member 32 extends into the sliding range of the start point designation member 31, so that their mutual positional relationships are not reversed.

This embodiment also provides the same effects as the first embodiment.

FIG. 6 shows a third embodiment of the present invention, in which light emitting diodes 27 are also provided at positions corresponding to the markers 37 and 38, respectively, and are used as a starting point specifying member and an end point specifying member, respectively. The structure is such that an automatic return navel type bushing switch 40, 41 is provided. In this case, all the light emitting diodes 27 are lit before the button switches 40 and 41 are operated, and each button switch 40
．． By the number of operations of 41, each light emitting diode 27 is
13 = The lights are turned off sequentially in the direction of the arrows marked on each switch 40 and 41. In this embodiment, switch 40.
Since it is possible to store the stroke designated by 41 in the operation control circuit 11, it is possible to eliminate the need for resetting when there is no change in the operation mode next time.

Therefore, in this embodiment as well, the same effects as in the first embodiment can be obtained, and there is no need for a sliding hole as in the above-mentioned sliding method, which is advantageous in terms of waterproofing.

FIG. 7 shows a fourth embodiment of the present invention, which differs from the third embodiment in the following points. That is,
Instead of the switch 40.41 in the third embodiment,
It has a configuration in which automatic return type bush switches 42 corresponding to the start point designation part or the end point designation member are respectively disposed at positions corresponding to the light emitting diodes 27, and any two of the plurality of switches 42 are operated. Then, of the operated switches 42, 42, the one earlier in time order functions as a starting point specifying member, and the later one functions as an end point specifying member. In this embodiment as well, it is possible to obtain the same effects as the third embodiment and the first embodiment.

FIG. 8 shows a fifth embodiment of the present invention, and this embodiment differs from the first embodiment in the following points.

That is, in this fifth embodiment, as can be seen from the figure, the washing operation execution time in the washing process and the dehydration operation execution time in the dehydration process are further divided, and the time display section 25 is adjusted accordingly. The display contents of .26 have been slightly changed, and the number and arrangement positions of light emitting diodes 27 have also been changed accordingly.

FIG. 9 shows a sixth embodiment of the present invention, which differs from the first embodiment in the following points. That is, regarding "dehydration" on the process display section 24, the operation details of that process are also displayed, and light emitting diodes 27 are arranged corresponding to each operation.

FIG. 10 shows a seventh embodiment of the present invention. In this seventh embodiment, a washing machine of a type used together with a dryer is illustrated. On the display section 24, after "dehydration", the words "drying" are added to indicate a drying process using a dryer.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with various modifications without departing from the scope of the invention.

[Effects of the Invention] As is clear from the description below, the present invention provides an operation mode in which a plurality of processes such as washing, washing, dewatering, etc. are combined in a predetermined time order, or in a single operation mode. an operation control circuit that selectively executes an operation mode of a stroke; a display section that displays each stroke according to the predetermined temporal order; It is equipped with a start point designation member and an end point designation member that arbitrarily designate subsequent end points, respectively, and sets the stroke included in the section from the start point to the end point designated by the start point designation member and the end point designation member in an operation mode. Accordingly, when setting the operation mode, the stroke corresponding to the start point and the stroke corresponding to the end point are set by the start point specifying member and the end point specifying member, respectively. You can set the desired driving mode by simply performing the specified operations.
Moreover, the contents of the strokes to be specified by each specified member can be easily determined on the display section that displays the strokes according to their chronological order, compared to the conventional method in which all the strokes included in the driving mode have to be set. This makes it extremely easy to set the operation mode.Furthermore, since we have an electrical setting structure using an operation control circuit instead of a mechanical setting structure, the specified stroke contents of each specified member can be unchanged for the next specification. If there is no change in the next driving mode setting, it can provide excellent effects such as the convenience of not having to perform setting operations.
