Abstract

PURPOSE:To report an abnormality on water feeding to a user at an initial stage to allow the user to perform immediate processing by activating a water feed abnormality reporting means if no water is fed when a water feed valve is operated after the washing action completion time is set by a reserve timer. CONSTITUTION:The input for a reserve timer setting means 2 is judged by the program stored in the memory unit 9a of a microcomputer 9, if an input is judged to exist, the presence of the input for a course setting means 3 is judged, if an input is judged to exist, a water feed valve driving means 7 is controlled by an output unit 9c, the input for a water feed judging means 5 during the action of a water feed valve for several seconds is judged. If no input exists, a water feed abnormality reporting means 8 is controlled by the output unit 9c, an abnormality of a water feed path is reported to a user. The microcomputer 9 then judges whether the cause of the water feed abnormality has been removed by the user, if the cause has been removed, it controls so that a series of sequential processes of washing, rinsing and dehydrating are completed within the completion time set by the reserve timer setting means 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a control device for a washing and dehydrating machine equipped with a reservation timer.

Conventional technology Conventionally, there is a control device for this type of dehydrating/washing machine.

After setting the reservation timer to set the end time of the washing operation, a course is set to set the sequential steps of washing, rinsing, and spin-drying, and if the start setting is performed, the set washing operation will be executed. It was controlled to end by the scheduled end time.

Problems to be Solved by the Invention In such a conventional configuration, water taps may not be opened, water supply hoses may not be connected properly, etc.
If the water supply valve (including the drive circuit) is abnormal, there is a problem in that the washing operation does not end at a predetermined time.

The present invention is intended to solve such problems, and when a user performs a reserved operation, the purpose of the present invention is to first check the operation of the water supply route to ensure that there is no problem with the set washing operation. .

Means for Solving the Problems In order to achieve the above object, the present invention provides a reservation timer setting means for setting the end time of the washing operation.

a course setting means for setting a series of sequential steps of washing, rinsing, and spin-drying; a water supply determining means for determining the presence or absence of water supply; a start/pause setting means for setting the start/stop of the washing operation; and the reservation timer setting. means, course setting means,
A control means for executing the stroke set by the water supply determination means and the start/pause setting means, a water supply valve driving means controlled by the control means, a display means for displaying setting contents and operation contents, and a water supply abnormality notification means. Equipped with.

After setting the reservation timer, if water is not supplied even after operating the water supply valve, the control means drives the nIJ water supply abnormality notification means to issue a water supply abnormality notification.

With this configuration, when the user sets a reservation timer, he or she can first check the operation of the water supply path and easily check whether there is any problem in executing the set washing operation.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to FIGS. 1 to 3.

The configuration of the control device for the dehydrating and washing machine in this embodiment will be explained with reference to FIG. That is, the control means 1 includes a reservation timer setting means 2. Course setting means 3. start/
The outputs of the temporary stop setting means 4 and the water supply determining means 6 are input. The control 1 means 1 performs washing according to the output contents of each of the setting means 2 to 6.

The display of rinsing and dehydration is executed by controlling the display means 6, and when the output of each setting means 2.3.4 is made, the water supply valve driving means 7 is controlled to keep the water supply valve open for a predetermined period of time. make it work. If the output of the water supply determining means 6 is not input after that.

The water supply abnormality notification means 8 is controlled to notify the water supply abnormality.

Next, the specific configuration of this embodiment will be explained with reference to FIG.
Reservation timer - setting means 2. Course setting means 3. The start/pause setting means 4 is a so-called button switch, and is arranged at a position where it can be easily operated by the user. The water supply determining means 5 determines the operation of the water supply path depending on whether water is present between a pair of electrodes. A microcomputer 9 receives signals from each of the setting means 2 to 5.
uses a program built into the storage unit 9a to determine the inputs of each of the setting means 2 to 6, and output signals for displaying settings and operation details, signals for driving the water supply valve, and the status of the water supply route. Output unit 9C for signal for notification
It occurs in

Specifically, a storage section 92L that stores washing, rinsing, and spin-drying time data, an input section 9b that inputs the outputs of each of the setting means 2 to 5, and a display means 6. Output unit 90 that outputs control signals to the water supply valve driving means 7 and the water supply abnormality notification means 8
．． It has an arithmetic control section 9d that controls each of the storage section 9a, input section 9b, and output section 9C and performs data comparison operations and the like.

Next, the operation of this embodiment will be explained based on the control flow of the microcomputer 9 shown in FIG.

First, in step 21, the microcomputer 9 determines whether an input has been made by the reservation timer setting means 2. If it is determined that input has been made.

In step 22, it is determined whether or not an input has been made by the course setting means 3. If it is determined that an input has been made, it is determined in step 23 whether or not an input has been made by the start/pause setting means 4. . If it is determined that the input has been made, the water supply valve driving means 7 is activated in step 24.
to operate the water supply valve for a few seconds. During the water supply valve operation for several seconds, it is determined in step 25 whether or not there is an input from the water supply determining means 6. If no input is made, the water supply abnormality notification means 8 is controlled in step 26 to notify the user of the abnormality in the water supply route by sound or light. Thereafter, in step 27, it is determined whether the user has removed the cause of the water supply abnormality (for example, forgetting to open the water tap, forgetting to connect the water supply hose, etc.).

If the cause of the water supply abnormality is removed, step 24 is performed again.
Return to If an input is received from the water supply determination means 6 in step 26, then in step 28 the series of washing, rinsing and spin-drying set by the course setting means 3 is executed at the end time set by the reservation timer setting means 2. The process is controlled to complete. The water supply valve of Nutenop 24 was set to operate for several seconds when the user was near the washing machine.

This is done in consideration of the amount of time that can be dealt with immediately.

Effects of the Invention As described above, according to the present invention, immediately after the reservation timer is set, the water supply valve is operated to determine whether or not water flows through the five water supply routes. to notify the user and take immediate action.
A series of sequential steps of washing, rinsing, and dehydration can be performed reliably.
