Abstract

PURPOSE:To prevent washing from being not-executed in a condition that washing agent quantity is lacked to the utmost by counting an operating time, storing a counted result and operating an announcing means when a stored value goes over a prescribed value. CONSTITUTION:As the washing agent is successively inputted from a hopper, the integrated operation time, namely, integrated value of a washing agent automatic inputting device is increased and the turning-off number of a light emitting diode 22 in a washing agent remaining quantity display part 20 is also increased. However, when the integrated value goes over the prescribed value, normal operation not to be reserved is executed and further it is judged that the integrated value goes over the prescribed value. In correspondence to the judgement, announcement that the remaining quantity of the washing agent is decreased so as to need supply is executed by alternatively turning-on and off the right side half and left side half of the light emitting diode 22 in the washing remaining quantity display part 20 and ringing a buzzer 31, for example. At such a time, a prescribed standby time is obtained and it is delayed that operation is started. Thus, the supply of the washing agent is promoted to a user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a washing machine with an automatic detergent dosing device capable of automatically dosing detergent.

(Prior Art) In recent years, washing machines equipped with automatic detergent dosing devices that can automatically dispense detergent have been provided.

However, in this type of lever, detergent for multiple doses is stored and can be automatically dispensed one dose each time the machine is operated.

(Problem to be solved by the invention) However, in the case of the conventional detergent, the remaining amount of detergent stored is 1
When the amount is reduced to less than the required amount, forgetting to replenish it,
When operation is started, washing is performed with an insufficient amount of detergent, resulting in a problem in that the desired washing effect cannot be obtained. Particularly, such problems tend to occur when the user leaves the washing machine due to the slow operation of the washing machine, which has an adjustment function for operation.

The present invention has been made in view of the above-mentioned circumstances, and therefore, its 1) purpose is to prevent laundry from being carried out with an insufficient amount of detergent as much as possible, and in particular to provide a reservation function for driving. To provide a washing machine with an automatic detergent dispensing device that can more reliably prevent this.

[Structure of the Invention] (Means for Solving the Problems) A washing machine with an automatic detergent dosing device of the present invention includes an integrating means for accumulating the operating time of the automatic detergent dispensing device, and a memory for storing the integration result by the integrating means. The present invention is characterized in that it comprises: a means for notifying the user; and a notifying means for activating the notifying means when the stored value of the storing means exceeds a predetermined value.

In this case, if the vehicle is equipped with a reservation function for driving, it is preferable not to accept input regarding the reservation function when the stored value of the storage means exceeds a predetermined value.

(Function) According to the above means, each time the automatic detergent dispensing device operates, the stored detergent gradually decreases, so by integrating and storing the operating time, the amount of detergent used, in other words, the remaining amount, can be calculated. Can be memorized.

Therefore, by activating the notification means when the stored value exceeds a predetermined value, the user can be informed that the remaining amount of detergent is less than the predetermined amount. It is possible to prevent laundry from being carried out in a state where there is insufficient water as much as possible.

In addition, for those equipped with a driving reservation function,
When the stored value of the storage means exceeds a predetermined value, no input is accepted for the discount function, which more reliably prevents washing with an insufficient amount of detergent. Get L.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

First, in Figure 2, 1 is the outer box of a fully automatic washing machine, 2 is the top cover, and 3 is the top cover 2.
4 is a lid provided at the center of the top cover 2; 5 is a rear panel provided at the rear edge of the top cover 2; An automatic detergent dispenser 6 is provided.

In detail, the automatic detergent dispenser 6 is as shown in FIG.
A coil 9 as a detergent delivery member and an agitator 10 that rotates in tandem with the rotation of the coil 9 are incorporated into a detachable hopper 8 that accommodates detergent, particularly powdered detergent 7, for multiple washing cycles. The coil 9 is rotated by a motor 11 disposed outside the hopper 8 (inside the rear panel 5) via a drive gear 12 and a driven gear 13. A small lid 15 is provided for a detergent outlet 14 for discharging the detergent 7 to be sent, which is normally closed and opened when the hopper 8 is attached. Reference numeral 16 designates a detergent receiving portion formed in the recessed portion of the rear panel 5 directly below the detergent outlet 14, into which a water supply device 19 connected to the water supply outlet 18 of the water supply valve 17 faces from the rear as shown in FIG. In other words, it is a water supply waterway, and its gradually descending tip faces a washing tub (not shown) disposed inside the outer box 1.

On the other hand, 20 shown in FIG. 5 is a detergent remaining amount display section provided on the operation panel 3 in parallel with the detergent switching operation section 21.
For example, the required number of light emitting diodes 22 that also serve as notification means is 1.
They are arranged in rows, and the number of them is equal to the total energization time to the motor 11 required to take out all the detergent 7 that has been filled into the hopper 8 in one cycle. The number is calculated by dividing the number by the time required for energizing the motor 11 to dispense the melon detergent 7 required for standard washing. However, among the light emitting diodes 22, the one on the left end in the figure that remains emitting light as the detergent 7 continues to be added and the one in front of it emit light in a different color from the others. In addition, a "replenishment" text display 23 is provided at the rear near the item that remains emitted at the end to prompt replenishment of the detergent 7, and conversely, at the rear near the item at the right end of the figure where the light goes out first. is provided with a character display 24 indicating "full" indicating that the inside of the hopper 8 is full of detergent 7. Further, in the front part of such detergent remaining amount display section 20, there is a memory which will be described later and the display state of the remaining amount of detergent 7 by the detergent remaining amount display section 20.

A reset input switch 25 is provided for resetting the stored contents regarding the injection of the detergent 7.

On the other hand, a changeover switch 26 is provided at the detergent changeover I/y external 21.
For example, the switching contents can be changed to five light emitting diodes 27, "more", "soubo", "less", "new model", etc.
Display section 2 represented by 5 kinds of character display 28 of "No input"
We have established one.

In FIG. 6, reference numeral 30 denotes a control device using a microcomputer, which is both an integrating means and an alarming means, which controls the motor 11 of the automatic detergent dosing device 6 and the light emission of the detergent remaining amount display section 20. A diode 22, a buzzer 31 as a notification means, a memory 32 as a storage means,
The changeover switch 26 of the detergent changeover operation section 21 and the reset input switch 25 are connected.

Next, the operation of the above structure will be described. First, before use, the detergent 7 is filled into the hopper 8 of the automatic detergent dosing device 6. Then, when the power switch (not shown) is operated and the reset input switch 25 is operated, the control device 3
0 receives the reset input, resets the stored contents of the memory 32 regarding the injection of the detergent 7, especially the stored value of the accumulated operating time of the automatic detergent dosing device 6, which will be explained later, and at the same time resets the stored value of the accumulated operating time of the automatic detergent dosing device 6, which will be explained later. All 20 light emitting diodes 22 are made to emit light.

On the other hand, when the power is turned on, the control device 30 starts its operation, and as shown in FIG. 1, it is determined in step Sl whether or not the washing operation is a reserved operation. If it is determined that it is a reserved operation, then in step S2 it is determined whether or not the operation is a course in which detergent 7 is added, and it is determined here that it is a course in which detergent 7 is added. If so, then in step S3, the stored value TI of the cumulative operation time of the automatic detergent dosing device 6 is set to a predetermined value, for example, the value T when the detergent 7 is used until the remaining amount is deemed to be insufficient for one wash. Decide whether you have passed or not.

Of course, detergent 7 has not been added at all here yet.
Therefore, even though the automatic detergent dosing device 6 is not operating at all yet, the operating time of the automatic detergent dosing device 6, which is accumulated and stored as described later, is the same as that of the above-mentioned reset input switch 25.
It remains at "0" as reset by the operation, and therefore it never exceeds the predetermined value T. For this reason,
Since it is determined that the remaining amount of detergent 7 is sufficient for at least one more wash, a reserved operation is then started in step S4. Therefore, in the second reserved operation, the operation is executed after a predetermined reserved time, and if the operation is executed, in this case, the detergent automatic dosing device 6 is activated because it is a course in which the detergent 7 is added. Motor 11 is energized and drive gear 1
2 and a driven gear 13, a coil 9, which is a detergent delivery member, is rotationally driven. Detergent 7 is thus dispensed from detergent outlet 14 of hopper 8 and falls onto detergent receiver 16 .

At this time, the water supply valve 17 is also energized, and water is supplied from the water supply device 19 onto the detergent receiver 16, so that the detergent 7 that has fallen onto the detergent receiver 16 is absorbed together with the water. It is supplied into a washing tub (not shown). Further, at this time, the step S5 sets the power supply time to the motor 11 as the operating time of the automatic detergent dosing device 6.
'', and the result of the integration (integrated value Tt) is given to the memory 32 and stored. In addition, the detergent remaining amount display section 20
Then, the number of light emitting diodes 22 corresponding to the integrated value Tl (in this case, if the "lapel pin" is set with the changeover switch 26 of the detergent changeover display section 21, one of the rightmost ones in FIG. 5) is activated.
is extinguished, and a display indicating that the remaining amount of detergent 7 has decreased by that amount is displayed.

On the other hand, if it is determined in the previous step Sl that the operation is not a reserved operation, then in step S6 it is determined whether or not the operation is a course in which the detergent 7 is added. If it is determined that the course includes dispensing, then in step S7 it is determined whether the stored value T1 of the cumulative operating time of the automatic detergent dispensing device 6 (cumulative energizing time of the motor 11) exceeds the predetermined value T. make a judgment. Of course, here too, the operating time of the automatic detergent dosing device 6 is "0" at first, and the predetermined value T
As described above, it is determined that there is enough detergent 7 for at least one more wash. Therefore, the operation is then started in step S8. In this case, the operation is immediately executed, and when the operation is executed, the detergent 7 is added at the above-mentioned time, and furthermore, at this time, in step S9, the detergent automatic injection device 6 similar to the above-mentioned The operating time of the controller 20 is integrated, and the integrated result (integrated riiTt) is given to the memory 32 and stored.

Also, in the detergent remaining amount display section 20, similarly to the above, the number of light emitting diodes 22 corresponding to the integrated value T1 is extinguished.
It is displayed that the remaining amount of detergent 7 has decreased by that amount.

Incidentally, if it is determined in the above-mentioned step S6 and the previous step S2 that the course does not include adding the detergent 7, the operation is immediately started from step S6 and then in step S8, and from step S2, the operation is started immediately. Next step S
4 to start reserved operation.

Now, as the above-mentioned use is repeated, as the detergent 7 is gradually added from the hopper 8, the cumulative operating time of the automatic detergent dosing device 6, that is, the cumulative value T! increases, and the number of extinctions of the light emitting diodes 22 of the detergent remaining amount display unit 20 also increases, but when the integrated value TI exceeds the predetermined value T, normal operation without reservation is performed and detergent 7 is added. In step S7 of the course of
It is determined that the limit has been exceeded, and accordingly step S1
0, the remaining amount of the detergent 7 has decreased to the point that it needs to be refilled. For example, the detergent display section 20 can be notified by alternately emitting and extinguishing the right side "1- number" and the left-hand side number of the light-emitting diode 22, and by extinguishing the light by a buzzer. 31. At this time, a predetermined waiting time is provided to delay the start of operation, thereby prompting the user to replenish detergent 7. After a period of time, the operation is started in step S8 in the same manner as described above.

On the other hand, if it is determined that the integrated value T1 has exceeded the predetermined value T in step S3 of the course of performing reserved operation and adding 70 detergents, the reservation function is then activated in step S11 accordingly. For example, the operation of not accepting the operation of the star key (not shown) is performed. Also, at this time, a notification that the remaining amount of the detergent 7 has decreased to the point that it needs to be refilled (input regarding the reservation function is not accepted) is sent, for example, to the light emitting diode 22 of the detergent display section 20.
This is done by emitting and extinguishing all of them at once. However, this is repeated until the previous reset input switch 25 is operated, and this is determined in step S12, and if the reset input switch 25 is operated (the detergent 7 is replenished into the hopper 8), the next In step S13, memory 3
ta la T t in step S 2 is reset, and then reserved operation is started in step S 4 .

In addition, the specific content of the notification is not limited to the above in any case, and each notification means also serves as a detergent remaining amount display means, and may also be either a light emitting diode or a buzzer. It is not limited to the above-mentioned one, or it may be one or the other. In addition, the content of not accepting input for the reservation function may be other than the above, such as making it impossible to select a reserved operation, or making it impossible to set the reservation time. Furthermore, the specific structure for dispensing detergent in the automatic detergent dispensing device is not limited to that described above.

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

[Effects of the Invention] The present invention is as explained above, and has the following effects.

In the washing machine with an automatic detergent dispenser according to claim 1, 21
Since the notification means is activated when the stored value of the cumulative operation time of the automatic detergent dispensing device exceeds a predetermined value, the user is notified when the remaining amount of detergent becomes less than the predetermined amount. Therefore, washing with an insufficient amount of detergent can be prevented as much as possible.

The washing machine with an automatic detergent dispensing device according to claim 2 has a reservation function for operation H, and when the stored value of the 200 million means exceeds a predetermined value, input for the reservation function is accepted. Therefore, it is possible to more reliably prevent laundry from being carried out with an insufficient amount of detergent.
