Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a two-tub washing machine that includes a microcomputer and controls dehydration operation.

[Technical background of the invention] Conventionally, in a two-tub type washing machine, when performing a washing operation in a washing tub, various washing modes are provided in order to perform a washing operation corresponding to the amount of laundry. I am trying to set it. For example, with the water flow switch,
The washing water flow can be set to "strong", "medium" or "weak" as appropriate, and the washing operation time set switch can be used to set the washing time to "15 minutes", "10 minutes", "7 minutes", "5", for example. Minutes "," 2
It is set to any one of "minutes", and further, the supply water level (overflow water level) at the time of rinsing is set to any of "high", "medium", and "low" by the supply water level changeover switch. In this case, the dewatering mode for the dewatering operation performed in the dewatering tank is also appropriately set to match the amount of laundry (the amount of the article to be dehydrated). For example, by setting the dehydration operation time set switch, the dehydration time can be set to "5 minutes", "3 minutes", "1".
It is set to either "minute" or "1/4 minute".

[Problems of background art] However, in the above-mentioned conventional one, the dehydration operation time, which is the dehydration mode for the dehydration operation, is "3 minutes" when the power is turned on regardless of the washing mode for the washing operation.
Or, since it is set to "5 minutes", when the washing mode is set according to the amount of laundry and the washing operation is finished in that washing mode, the laundry is dehydrated, Again, the dehydration mode had to be set in accordance with the amount of the laundry, and the setting operation related to the control of the dehydration operation was really troublesome.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object thereof is to set the degree of strength of the dehydration mode for the dehydration operation when the laundry after the washing is dehydrated after the washing operation. (EN) Provided is a two-tub type washing machine which can eliminate the operation.

[Summary of the Invention] The present invention is configured such that a washing operation is performed in a washing tank and a dehydration operation is performed in a dehydration tank. The degree of dehydration mode for the dehydration operation is automatically set in the microcomputer according to the strength, so that the setting operation by the user is unnecessary.

[Embodiment of the Invention] A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. First, in FIG. 2 showing the operation panel portion, 1 is a power switch, 2 is a water flow changeover switch, and this water flow changeover switch 2 sets the water flow for a detergent washing operation and a rinsing operation to “strong” based on the number of inputs. , “Medium” or “Weak”. 3 is a washing operation time set switch, which determines the washing time for detergent washing operation and rinsing operation on the basis of the number of times of input, "15 minutes", "10 minutes", "7 minutes", "5".
It is set to either "minute" or "2 minutes". Reference numeral 4 denotes a dehydration operation time set switch, which sets the dehydration operation time to "5 minutes", "3 minutes", "1" based on the number of inputs.
Either "minute" or "1/4 minute" is set. Thus, each of the switches 2 to 4 is adapted to give a signal of a pulse number corresponding to the setting contents thereof, that is, the number of inputs to the microcomputer 22 described later. Reference numeral 5 denotes a water supply level switch, which sets the rinsing water level (water supply level) in the rinsing operation to, for example, "high", "medium", or "low" based on the slide operation. The water level changeover switch 5 is adapted to give signals of different pulse numbers to the microcomputer 22 depending on the setting contents thereof, that is, depending on the operating position. Each of these switches 2 to 5 is a switch for setting a washing mode having an intensity corresponding to the amount of laundry. 6 is a start switch for washing operation, and 7 is a start switch for dehydration operation. 8 to 19 are light emitting diodes, and the light emitting diode 8 is for displaying "strong" water current, and the light emitting diode 9
Is for "medium" water flow display, light emitting diode 10 is for "weak" water flow display, light emitting diode 11 is for washing operation time "15 minutes", light emitting diode 12 is for washing operation time "10 minutes",
Light-emitting diode 13 is for washing operation time "7 minutes", light-emitting diode 14 is for washing operation time "5 minutes", light-emitting diode 15 is for washing operation time "2 minutes", light-emitting diode 16 is for dehydration operation time " 5 minutes "display, light emitting diode 17
Indicates the dehydration operation time "3 minutes", the light emitting diode 18 indicates the dehydration operation time "1 minute", and the light emitting diode 19 indicates the dehydration operation time "1/4 minute". 20 is the drainage switching knob, 2
1 is the water injection switching knob. Next, in FIG. 1, reference numeral 22 is a microcomputer, which controls the dehydration operation and the washing operation in this embodiment. The microcomputer 22 outputs a drive signal to each of the light emitting diodes 8 to 19 based on an input signal given from each of the switches 2 to 5 and a signal from each of the switches 2 to 5 to a washing motor drive circuit 23. A drive signal is output according to the content of the washing mode for the washing operation, and a drive signal corresponding to the content of the dehydration mode for the dehydration operation is output to the dehydration motor drive circuit 24. Motor 25 and dehydration motor 26
Are driven according to the washing mode and the dehydration mode, respectively. Specifically, as understood from Fig. 3, the length of the dehydration operation time which is the dehydration mode is automatically set according to the strength of the water flow which is the wash mode. When set to "strong", the dehydration operation time is set to "5 minutes" and the water flow is "medium".
If the water flow is set to "weak", the dehydration operation time is set to "1 minute". Therefore, after the washing operation, a drive signal having a time width corresponding to the set dehydration operation time is output to the dehydration motor 26. Here, the correlation between the amount of laundry (load), the water flow during the washing operation (washing mode) and the dehydration operating time during the dehydration operation (dehydration mode) will be described, as shown in FIG. If the amount of laundry is small, the strength of the water flow in the washing mode may be “weak”, and in this case, the dehydration operation time in the dehydration mode may be “short”. Then, as the amount of laundry becomes “large”, the water flow is also preferably “strong”, and in this case, the dehydration operation time is also preferably “long”. Thus, according to the above-described embodiment, when the water flow is set to "weak" for the washing operation in accordance with the amount of laundry being "small",
Since the dehydration time for the dehydration operation is also set to "short", it is not necessary for the user to set the dehydration operation time for performing the dehydration operation. As a result, the strength of the dehydration mode for the dehydration operation can be set. The operation can be eliminated, and thus convenient.

The present invention is not limited to the above embodiment, and the following modifications are possible.

That is, as the washing mode set according to the amount of laundry, the washing operation time and the water supply level also correspond to this, and therefore, it can be understood from FIG. 5 shown as the second embodiment of the present invention. Therefore, the dehydration operation time may be set according to the washing operation time set by the washing operation time set switch 3. In this case, when the set washing operation time is "15 minutes", the dehydration operation time is set. Set to [5 minutes],
Similarly, the set washing operation time is "10 minutes", "7 minutes" and "5".
When the set washing operation time is "2 minutes", the dehydration operation time is "1 minute".
You may make it set to each "minute". Further, as understood from FIG. 6 showing the third embodiment of the present invention, the dehydration operation time may be set in accordance with the water supply level set by the water level switch 5. In this case, the set water supply is set. The dehydration operation time may be set to "5 minutes" when the water level is "high", "3 minutes" when the water level is "medium", and "1 minute" when the water level is "low". .

Further, in each of the above-described embodiments, the dehydration operation time is illustrated as the dehydration mode. However, in the dehydration mode, the rotation speed of the dehydration motor 26 also corresponds to this.
The number of rotations may be changed and set.

In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

[Effects of the Invention] As is clear from the above description, the present invention provides a washing operation in a washing tank and a dehydration operation in a dehydration tank, which includes a microcomputer for controlling the dehydration operation,
The degree of strength of the dehydration mode for the dehydration operation is automatically set in the microcomputer according to the strength of the wash mode set for the cleaning operation. When the dehydration operation is subsequently performed, it is possible to eliminate the setting operation of the strength and weakness of the dehydration mode for the dehydration operation, thereby achieving an excellent effect.
