Description

Automatic water storage device using a washing machine

The present invention relates to an automatic water storage device using a washing machine in the singular, and more specifically, to input the predetermined singular date and time into the washing machine and to store the maximum quantity in the washing machine of the washing machine before the singular date and time arrives. The present invention relates to an automatic water storage device using a washing machine.

Recently, a washing machine is not only capable of automatically performing laundry administration such as washing, rinsing and dehydrating laundry, but also automatically inserting laundry detergent and fabric softener as needed. It is widely used and its size is also becoming larger.

FIG. 1 is a perspective view illustrating an external configuration of a general washing machine. As shown in FIG. 1, a laundry room 2 is provided in a main body 1, and a predetermined amount of laundry is stored in the laundry room 2. The laundry container 3 provided with the stirring blade 3a for washing is provided. In addition, a door 4 is installed at the top of the main body 1, and an operation panel 5 for selectively adjusting a washing course and the like is provided, and a detergent input device 6 for automatically introducing detergent is also installed. . On the other hand, although not shown in the figure is provided with a driving means for supplying and draining the wash water and operating the washing tub 3 and the stirring blade (3a).

In such a washing machine, the washing capacity is divided into the maximum washing capacity that can be washed once. Usually, a standard washing machine capable of washing 5 to 6 kg of laundry and a large washing machine capable of washing 6 to 9 kg of laundry and 10 kg It is roughly classified into a super capacity washing machine which can wash the above laundry.

If a water supply error occurs in the washing machine having the general structure as described above, the water supply situation in the washing tub according to the water situation after a predetermined time (for example, 5 minutes) by using a water level sensor that varies the frequency range according to the water level by an alarm circuit. If it is judged that it is not suitable for washing by stopping the water supply, the water supply is stopped and an alarm and a water supply error indication are given so that the water supply error can be alarmed early.

Fig. 2 shows a conventional washing machine water supply alarm circuit diagram. The input ports PI of the control means 7, which are microcomputers with built-in programs, include resistors R1 to R5, capacitors C1 and C2, and coils L. Normal water level detecting means 8 composed of inverters I1, I2, transistors Q1, and the like are connected to generate a natural oscillation frequency in response to a change in the water level pressure in the washing tub 3. That is, the iron core of the pressure sensor coil (L) is moved in accordance with the water level pressure of the washing container (3), so that the reactance value of the coil (L) is changed, and according to the changed reactance value and the values of the condensers (C1, C2) LC oscillation is performed, and the oscillation signal is turned on intermittently by the transistor Q1 via the resistor R3, so that the oscillation square wave is input to the port of the control means 7 through the resistor R5. In this way, in the water level detecting means 8, a certain natural frequency is generated according to the water level in the washing tub 3 and is input to the port PI of the control means 7, so that the control means 7 reads this constant oscillation frequency. Will be judged.

The output port of the control means 7 is also connected to a water supply valve drive means 9 composed of resistors R6 to R8, transistors Q2, triac T, condenser C3 and feed water valve V. The low signal output to the port turns on the transistor Q2 through the resistor R6. At the same time, since the triac (T) conducts by applying a trigger signal to the gate of the triac (T), power is applied to the water supply valve (V) to open the water supply valve (V), and water supply is started in the washing tub (3). Therefore, the output signal of the port PO1 controls the opening and closing of the water supply valve V.

Alarm output means 10 composed of resistors R8 to R11, transistors Q3 and Q4 and buzzer B is connected to output port PO2, and a low signal is output to port PO2 in case of water supply failure. Transistor Q3 is turned off through R8, and transistor Q4 is turned on because a high potential through resistor R10 is applied to the base of transistor Q4 at its collector end. At the same time, the DC power flows through the buzzer B and the resistor R11 to the emitter ground of the transistor Q4, and the buzzer B emits an emergency alarm.

In addition, the normal display means 11 is connected to the output ports PO3 to PO19 of the control means 7 to output a water supply failure signal in case of a water supply failure through the ports PO3 to PO19 to display a code for the water supply failure. Display.

3 is an internal configuration diagram of a control means, comprising a central processing unit (CPU), a ROM in which a driving program of a washing machine is embedded, and a RAM and an input / output interface capable of temporarily storing or reading data (ports of an input interface) The output of the water level detecting means 8 is input to PI, and the water supply valve driving means 9, the alarm generating means 10 and the display means 11 are connected to the ports PO1 to PO19 of the output interface. Information exchange and control of the internal components of (7) are controlled via a data bus, an address bus and a control bus, respectively.

The operation of the conventional washing machine water supply abnormality alarm circuit configured as described above will be described in detail with reference to FIG. 4.

Figure 4 shows a flow chart for explaining the operation of the conventional washing machine water supply abnormality alarm circuit, when the washing machine outputs a low signal to the output port (PO1) when the power is supplied to the washing machine and the desired washing course is selected and the start switch is turned on. To start the water supply. At this time, the initial oscillation frequency from the water level detecting means 8 is detected and the signal input to the port PI is read, and the control means 7 stores the data of the initial frequency in the RAM. After the start of the water supply, the elapse of a predetermined time is checked. When a predetermined time (for example, 5 minutes) elapses after the water supply, the frequency corresponding to the water level input through the water level detecting means 8 is read again.

At this time, the frequency signal read and the initial frequency signal stored in RAM are compared to determine whether there is a certain difference already set. At this time, there is a certain difference in the water supply state after a certain time from the initial water supply state. This means that there is no abnormality in the water supply situation for the washing process, so that the set water supply and normal washing operation are continuously performed.

However, if the initial frequency and the frequency after a certain time do not become constant, it means that there is an abnormality in water supply and the water level in the washing container 3 has not changed significantly. Therefore, the control means 7 stops outputting the low signal to the port PO1. To close the water supply valve (V) and stop the water supply at the same time, output a low signal to the port (PO2) to apply a signal to the buzzer (B) to give an alarm and output the signal controlled by the ports (PO3 to PO19) It operates to display the code indication when water supply error occurs.

However, the water supply abnormality alarm circuit of the washing machine does not provide a fundamental solution in case of water shortage or water supply abnormality, but only serves as an alarm when water supply abnormality occurs. In addition, when the user goes out in a short time can not store the water in advance, there is a problem that causes inconvenience when trying to use for urgent business.

Therefore, the present invention was devised to solve such a problem, and an object of the present invention is to input the date and time of the singular number into the time storage unit of the washing machine, and when the reservation time is reached, the washing machine in the washing machine automatically reaches the highest level. It is to provide an automatic water storage device using a washing machine when water can be stored as a short time.

The present invention for achieving the above object is provided with a control panel for selectively adjusting the washing course and the microcomputer that is programmed to perform the washing process by the clock circuit unit for counting the current date and time and the signal of the operation panel; By using the water supply valve driver and water level sensor to open and close the water supply valve under the control of the microcomputer, the water level detection unit detects the water level in the washing tub of the washing machine and outputs an alarm sound through the buzzer in case of water supply abnormality. In the water supply abnormality alarm device of the washing machine consisting of an alarm generating unit and a display unit for outputting an error occurrence in case of water supply failure through the LCD, located on the operating panel of the washing machine, and a time setting unit for setting the reservation time by the user's selection; Time storage unit and clock circuit unit for storing the data input to the time setting unit to the EEPROM Comparing unit comparing the current date and time of the time storage unit and outputting a high signal if the current date and time of the clock circuit unit and the time storage unit match, and outputting a low signal if the current date and time of the clock circuit unit and the time storage unit do not match. And a water supply valve driving signal unit for opening and closing the water supply valve by a signal output from the comparing unit.
