Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention includes automatic injection of detergent and automatic supply of water at a certain time in the future by reservation setting based on switch input. The present invention relates to a washing machine having a reservation function for executing a washing operation.

(Prior Art) Recent washing machines are equipped with automatic detergent dosing devices, and these machines perform a washing process that includes automatic detergent dosing and water supply.

An automatic washing operation that automatically controls the rinsing process and the dehydration process is performed automatically. Furthermore, among the devices that are capable of performing such an automatic washing operation, there are some that have approximately H functions.

In this device, the above-mentioned automatic washing operation is executed at a certain time after the current time by setting a reservation based on the switch manually (including setting the desired time to start or end the operation, course setting, etc.). .

(Problem to be Solved by the Invention) By the way, in an automatic washing operation that includes automatic injection of detergent and automatic water supply, tap water is automatically supplied into the washing tank at the beginning of the washing process, and detergent is automatically added. However, if the amount of detergent stored in the automatic detergent dispenser is small, sufficient washing cannot be done. In addition, if the water faucet connected to the water supply hose of the washing machine is left closed, water will not be supplied to the tank, and only this detergent will be poured into the laundry, causing the fluorescent agent in the detergent to disappear. It sticks to the laundry and discolors it.

However, when starting an automatic washing operation immediately at present, it is difficult for the user to avoid problems such as insufficient supply of detergent or no water supply, which tend to occur at the beginning of the washing process, that is, at the beginning of the automatic washing operation. You will often notice this, and in this case you can take measures such as replenishing detergent or opening the water faucet. However, when using the reservation function to start an automatic washing operation at a time in the future, the scheduled automatic washing operation is often started in the middle of the night or when the user goes to bed, so the user has to There is a problem in that the occurrence of the above-mentioned stone condition is not recognized, and therefore the cause of the problem (insufficient detergent, forgetting to open the faucet) is not resolved, and the above-mentioned problem is left as it is. Ta.

The present invention has been made in view of the above circumstances, and its purpose is to:
Lack of detergent or opening the faucet 1. To provide a washing machine which can prevent the occurrence of problems such as insufficient washing or discoloration of laundry by prompting confirmation of causes of poor washing such as forgetting washing.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes an automatic detergent dispensing device and various display devices, and has 11 settings based on switch inputs to automatically dispense detergent at a certain time in the future. In a device that has a reservation function for executing an automatic washing operation including automatic detergent injection and automatic water supply, when setting the reservation, the display related to automatic detergent injection and automatic water supply blinks for a predetermined period of time. Alternatively, the present invention is characterized by providing a confirmation display control means for controlling the display to turn on.

(Function) According to the above means, when setting a reservation, the confirmation display control means controls the display related to automatic detergent injection and automatic water supply to blink or turn on for a predetermined period of time.
When the user is near the washing machine, the flashing or lighting of the indicator alerts the user to confirmation or caution regarding opening and closing of the detergent spout and faucet.

Since the blinking or lighting indicators are various indicators originally included in the washing machine, there is no need to provide a dedicated indicator, and the configuration can be simplified.

(Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

Now, the microcomputer 46 has a control program related to the reservation function, and functions as follows according to the control program.

Now, FIG. 6 shows the control contents of the microcomputer 46, and immediately after the power is turned on, initial settings are executed as shown in step S1. In this initial setting process, the "standard" course is set as the driving course, and the following:
Set the washing time to ``10 minutes'', the number of washes to 12 times'', the dehydration execution time to 15 minutes'', and the detergent dish to ``Standard''. Then, as shown in step S2, the display corresponding to each setting is turned on, and the time display 30 is made to display the current time.

In the next step S3, input from switches 20 to 28 is awaited. In the next step S4, it is determined whether the first inputted switch (the first operated switch) is the reservation function designation switch 27, and if it is the reservation function designation switch 27, step S5 is performed. The reservation display 31 is turned on as shown in , and the reservation setting process shown in steps S6 to 514 is executed.

That is, in step S6, the switch waits for human power, and if there is a switch, in step S7, the human power is set to the "hour" setting switch 28. It is determined whether the switch from the "minute" setting switch 29 is manually operated, and if this is the case, the desired start time of the automatic washing operation is set as shown in step S8, and the desired start time of the automatic washing operation is set as shown in step S9. The desired time is displayed on the time display device 30. Each of these switches 2

The process jumps to step S9 and proceeds to step 510. In step SIO, it is determined whether the input in step S6 is one of the switches 20 to 24, and if this is the case, settings are made according to the switch in step Sli, and step S1
In step 2, the display device is turned on according to the set contents.

If it is determined in step SIO that it is not one of the switches 20 to 24, then step SIO
11. Jump to step S12 and proceed to step S13. In step S13, it is determined whether or not the desired start time has been set. If the desired start time has not been set, the process returns to step S6, and if it has been set, step S1
4, and in this step S14, the step S
It is determined whether or not the manual switch input at step 6 was an input from the operation start switch 25. If the input is not from the operation start switch 25, the process returns to step S6 and waits for a switch input, and if the input is from the operation start switch 25, it means that the reservation setting has been completed and the process moves to the next step S15. . In this step S15,
Among the indicators 32 to 45, indicators 43, 44, and 45 are for displaying the amount of detergent, which is related to automatic detergent addition, and display units 44 and 45 are for displaying washing time, which can be said to be related to automatic water supply because water is automatically supplied during the washing process. The indicators 35, 36, and 37 are made to blink for a certain period of time. At the same time, other indicators 32°33.
34, 38, 39.40, and 41.42 are all turned off. Furthermore, the buzzer 52 is activated. J: The period display state is shown in FIG.

After that, the process moves to step S16 to execute control regarding the reservation function. This reservation function waits for a required time until the automatic washing operation starts according to the above-mentioned desired start time setting, and then executes the automatic washing operation. If there is an input from a switch other than the reservation function switch 27 in step S3, control is executed for the normal function (immediate operation function) as shown in step S17, and then the process returns to step S3.

According to this embodiment, when setting a reservation, the display 3
Displays 43, 44, 45, 35, 36, and 37 related to automatic detergent injection and automatic water supply among 2 to 45 are made to blink, so when the user is near the washing machine, the amount of detergent and the amount of detergent can be checked. It is possible to check or call attention to the opening and closing of the faucet, and therefore, even if the automatic washing operation is started at a time later than the current one, even if the automatic washing operation is started at a later time, it is possible to check or call attention to the opening and closing of the faucet. This makes it possible to eliminate the cause of problems such as forgetting to release.

As a result, problems such as insufficient washing or discoloration of laundry can be avoided. Furthermore, the blinking display 4
3, 44, 45, 35, 36, and 37 are originally provided in the washing machine, so there is no need to provide a dedicated display, and the configuration can be simplified. In particular, since the buzzer 52 is also used to notify the user, the above-mentioned confirmation can be further facilitated.
