Abstract

PURPOSE:To improve operability by automatically setting only the execution of dehydration on the side of a dehydrating tank when setting operation from washing to rinsing is executed in a washing tank. CONSTITUTION:When it is judged that rinsing is set on the side of a washing tank 2, it is judged next whether rinsing is set in a dehydrating tank 3 or not. when the set is executed, it is judged next whether the dehydrating tank 3 is under operation or not. When the dehydrating tank is not under operation, the set of rinsing is automatically canceled on the side of the dehydrating tank 3. Afterwards, operation in the washing tank 2 or operation in the dehydrating tank 3 is executed with set contents. Thus, since the set of rinsing is canceled and automatic setting is executed to execute only the dehydration when the setting operation from washing to rinsing is executed on the side of the washing tank 2 and the set of rinsing is executed on the side of the dehydrating tank 3, it is not necessary to successively execute operation on a user side to cancel the set of rinsing on the side of the dehydrating tank 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a washing machine capable of rinsing laundry in a dehydration tank.

(Prior Art) In recent years, washing machines have been provided in which, in addition to a washing tub capable of washing and rinsing, a spin-drying tub installed in parallel allows washing and spin-drying of the laundry.

However, the initial settings when the power is turned on or when the operation ends are usually standard. For example, the washing tub side is set to only wash, and the spin tub side is set to everything from rinsing to spin-drying. Settings are made to perform each of these.

(Problem to be Solved by the Invention) However, with the initial settings as described above, unlike the settings, the washing tub washes and then rinses, and the spin tub only spins water. When doing this, the rinsing setting must be canceled one by one on the dehydration tank side, and depending on the type of product, the operation cannot be done in one go, but may require multiple operations, which is cumbersome. There was a problem.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide an excellent method for improving operability when washing and rinsing laundry in a washing tub, and only dehydrating the laundry in a spin-drying tub. There is a washing machine provided.

[Structure of the Invention] (Means for Solving the Problem) The washing machine of the present invention includes a washing tub capable of washing and rinsing laundry, and a spin-drying tub capable of rinsing and dehydrating the laundry. , and is characterized in that it is equipped with a control means that automatically sets the spin-drying tank to perform only spin-drying when a setting operation for washing to rinsing is performed on the washing-tub side. It is.

(Function) According to the above means, when a setting operation for performing washing to rinsing is performed on the washing tub side, there is no need to perform an operation for canceling the rinsing setting on the spin-drying tub side.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

First, as shown in FIG. 2, a washing machine Iw2 and a dehydration tank 3 are arranged side by side in the outer box 1 of the entire washing machine. Washing tub 2
Inside, a stirring body 4 is arranged at the bottom, and this stirring body 4
is rotated by a washing motor 5 disposed below outside the washing tub 2 via a belt transmission mechanism 6. On the other hand, in this case, a dehydration basket 8 having a water spray tube 7 in the center is disposed in the dehydration #fI3, and this dehydration basket 8 is disposed in the lower part outside the dehydration tank 3. It is designed to be directly rotationally driven by a dewatering motor 9.

An operation box 10 is arranged on the outer box 1, and this operation box 1
0, a washing tank side water supply valve 12 and a dehydration tank side water supply valve 13 connected to a water faucet (not shown) with a water supply hose 11 are arranged side by side, and the washing tank side water supply valve 12 is connected to a washing tank side water supply channel 14. A water injector 15 on the washing tank side faces into the washing tub 2, and a water supply valve 13 on the dehydration tank side faces into the water sprinkling tube 7 through a water supply channel 16 on the dehydration tank side and a water injector 17 on the dehydration tank side.

Further, an operation panel 18 is provided on the front side of the washing tub 2 side of the operation box 10. As shown in FIG. 3 in detail, this operation panel 18 includes a "water flow" key 19 for selecting the strength of the washing water flow, and a "wash" key 20 for selecting the washing time, as the washing tub side operation section. , "Rinse" key 21 to select rinsing time and number of times, "Drain" key 22 to select whether or not to drain water from the washing tub 2, "Start/Stop" key to select start of operation and stop at - There are 23
In addition, the dehydration tank side operation section includes a "shower rinse" key 24 for selecting the rinsing time and number of times, a "dehydration" key 25 for selecting the dehydration time, and a "dehydration" key 25 for selecting the dehydration time, and a "shower rinse" key 25 for selecting the dehydration time, and a "dehydration" key 25 for increasing the rinsing time when the water supply pressure is low. A "low water pressure" key 26, a "start/stop at -" key 27 for selecting the start of operation and a stop at - are provided, and both "start/stop at -" keys 23.2 are provided.
Display LEDs 28 to 34 and necessary display characters 35 to 39 corresponding to the remaining keys except 7 are provided.

Inside the operation box 10, a control device 40, which is a control means, is arranged behind the operation panel 18. This control device 40 is also configured in detail, for example, by a microcomputer, and as shown in FIG.
An oscillation output is sent from the operation panel 18, a key operation signal for washing and dehydration is sent from the operation panel 18, a water level detection signal for the washing tub 2 is sent from the water level sensor 43, an initialization circuit 44
An initialization signal is inputted from the waveform shaping circuit 45, and a waveform shaping signal is inputted from the waveform shaping circuit 45, respectively, and the washing tub side water supply valve 12. , washing motor 5, drain valve 46, dehydration tank side water supply valve 13, dehydration motor 9
The energization states of the display LEDs 28 to 34 of the operation panel 18 are controlled directly through drive circuits 47 to 51, respectively.

Therefore, the details of control by the control device 40 will be described below with reference to FIG. 1.

That is, when the control device 40 starts operating by manually turning on the power, it first performs initial settings (step S1), and then displays the contents of the initial settings (step S2).

This display, for example, is shown in FIG.
．． It is as shown by the luminescence of No. 33 (see diagonal line),
Therefore, in this case, on the washing tub 2 side, the "standard" water flow is "1".
This means that the initial settings are such that only a 0-minute wash is performed, and on the dehydration tank 3 side, a ``standard'' rinse and a 3-minute dehydration are performed. Next, the control device 40 accepts a key operation by the user (step S3), and then determines whether or not the operation causes a rinse setting using the "rinse" key 21 on the washing tub 2 side (step S4). ).

Here, if there is no setting for rinsing on the washing tub 2 side mentioned above, the process jumps to the next step (step S5) and the initial setting or the rinsing setting on the washing tub 2 arbitrarily set by the user is performed. operation (for washing, the motor 5 drives the agitator 4) or in the dehydration tank 3 (for rinsing, the water supply valve 13 on the side of the dehydration tank 3 supplies water to the water spray cylinder 7, and the dehydration motor 9 drives the dehydration basket 8 to rotate) The dewatering is performed by rotating the dewatering basket 8 by the dewatering motor 9. When the operation in the washing tub 2 is completed (step S6), the display LEDs 28 and 29 on the washing tub 2 side are initialized. Step S7) returns to the state at the time of setting, and returns to step S3. Further, when the operation in the dehydration tank 3 is completed (step S8), the dehydration tank 3
Step S9) returns the side display LEDs 32 and 33 to the initial setting state, and returns to step S4.

On the other hand, if it is determined in step S4 that rinsing in the washing tub 2 side is set, then it is determined whether rinsing in the dehydration tub 3 is set (step 510).
If the setting has been made, it is then determined whether or not the vehicle is in operation (step 5ll), and if it is not in operation, as shown by the complete extinction of the display LED 32 in FIG. The rinsing setting on the dehydration tank 3 side is automatically canceled (step 512). Regarding other settings, if the default settings are used, the LEDs 28 and 29 shown in Figure 6 will be displayed.
．． 33 (see diagonal lines), and in this case, for rinsing on the washing tub 2 side, the display LE
As shown by the light emission of D30, "standard" is shown in the figure. Therefore, if they are set differently, the display LEDs 28, 29, 30, 33 will emit light differently depending on the content to display that information. After this, the process proceeds to step S5, and the set contents are operated in the washing tub 2 (for rinsing, the agitator 4 is rotated by the motor 5 similar to washing) or in the dehydrating tub 3.

Furthermore, in both cases where it is determined in step SIO that rinsing in the dehydration tank 3 is not set, and in both cases where it is determined in step Sll that the operation is in operation Φ, the process jumps to step S5.

According to this embodiment, when a setting operation for washing to rinsing is performed on the washing tub 2 side, if the rinsing setting is set on the spin-drying tub 3 side, the setting is canceled and only spin-drying is performed. This eliminates the need for the user to repeatedly cancel the rinsing setting on the dehydration tank 3 side. In particular, in a case like the one in this embodiment, the operation to cancel the rinsing setting on the dehydration tank 3 side is to press the "shower rinsing" key 24 as many times as necessary until all of the display LEDs 32 are no longer lit. By eliminating the need for such complicated operations, it is possible to improve operability.

Note that the rinsing performed in the dehydration tank 3 is not performed by alternately repeating the above-mentioned water supply to the water spray cylinder 7 by the water supply valve 13 on the dehydration tank 3 side and rotation of the dehydration basket 8 by the dehydration motor 9; The dewatering basket 8 may be rotated with water stored therein.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate changes within the scope of the gist.

[Effects of the Invention] As is clear from the above description, the washing machine of the present invention includes a washing tub capable of washing and rinsing laundry, and a dehydrator capable of rinsing and dehydrating laundry. This is because the device is equipped with a control means that automatically sets the dehydration tank to perform only spin-drying when a setting operation for washing to rinsing is performed in the washing tank. In this case, there is no need to perform the operation of canceling the rinsing setting on the dehydration tank side every time, and an excellent effect can be obtained in that operability can be improved.
