Meanwhile, the manipulation unit 300 may be provided as a touch device to enable touch input.

As described above, when the operation unit 300 has a touch input function and the operation unit 300 rotates together with the water extraction module 400, the touch substrate 320 provided in the operation unit 300 rotates together, and touch In the process of rotating the substrate 320 to both sides, the connection with the main substrate 190 fixed to the water purifier main body 100 is disconnected and then reconnected.

And, as the touch substrate 320 without the nonvolatile memory device is reset, the register value of the touch substrate 320 is initialized to a default value, and as a result, malfunction of the touch substrate 320 occurs. Occurs.

According to the present invention, the main substrate 190 may mean a microcomputer.

In addition, the main substrate 190 is provided with a non-volatile memory device, is fixed to the water purifier body 100, and maintains a fixed state when the operation unit 300 rotates with the water discharge module 400.

In addition, the touch substrate 320 and the main substrate 190 may be connected through a connection member 191.

For example, the connecting member 191 may be formed of an electric wire, and forms terminal portions 191a at both ends. The terminal portion 191a may be coupled while being inserted into a connection portion (not shown) formed in the touch substrate 320 and the main substrate 190.

When the manipulation unit 300 is rotated, the terminal unit 191a is temporarily disconnected from the connection unit (not shown) of the touch substrate 320 or the main substrate 190, and a connection may be disconnected.

In addition, since the main substrate 190 is provided with a nonvolatile memory device, the register value of the touch substrate 320 is stored.

The register value of the touch substrate 320 may be set on the main substrate 190 by a programmer when manufacturing a product.

In addition, the main substrate 190 may periodically read the register value of the touch substrate 320 through serial communication.

In addition, when the register value read from the touch substrate 320 is a default value, the main substrate 190 sets the register value of the touch substrate 320 when the product is manufactured, by a programmer. With, it can be reset.

In addition, the main substrate 190 may read the register value of the touch substrate 320 every 2 seconds.

Hereinafter, a control method of a water purifier including a main substrate 190 provided in the water purifier main body 100 as described above, and a touch substrate 320 provided in an operation unit 300 rotating based on the water purifier main body 100. Explain.

The control method of the water purifier according to the present invention is a setting step in which a register value is set from the main substrate 190 to the touch substrate 320, and after the setting step, determining whether a reference time has elapsed through a timer In the measurement step and in the measurement step, when a reference time (about 2 seconds) has elapsed, a determination step of determining whether the touch substrate 320 is reset, and in the determination step, the reset of the touch substrate 320 is performed. If it is determined, a reset step of resetting the register value from the main substrate 190 to the touch substrate 320.

At this time, when the register value read from the touch substrate 320 is a default value, it may be determined that the touch substrate 320 has been reset. That is, it may be determined that the connection between the touch substrate 320 and the main substrate 190 is temporarily disconnected and then connected.

In addition, in the measurement step, when the reference time (about 2 seconds) has elapsed, the step of initializing the timer proceeds consecutively, and then the determination step may proceed.

Also, the setting step may be performed only once, when the power is initially supplied to the water purifier.

7 is a flowchart of a method for controlling a water purifier according to another embodiment of the present invention.

Hereinafter, an embodiment of a method of controlling a water purifier according to the present invention will be described with reference to FIG. 7.

First, power is supplied to the water purifier. That is, power is supplied for the first time to use the water purifier.

Thereafter, a register value is set from the main substrate 190 to the touch substrate 320. (S11)

When manufacturing a product, the register value of the touch substrate 320 is input to the main substrate 190 by the programmer.

Then, the water purifier works normally.

In this process, it is determined whether or not the touch substrate 320 is reset, and when a reset is detected, the register value is reset from the main substrate 190 to the touch substrate 320.

In detail, it is determined whether the reference time (about 2 seconds) has elapsed through the timer. (S12)

Thereafter, when the reference time (about 2 seconds) has elapsed, the timer is initialized. (S13)

Therefore, the timer can determine whether the reference time (about 2 seconds) has elapsed again.

After the step S13, the main substrate 190 reads the register value of the touch substrate 320 (S14).

The step S14 may be performed by requesting specific register data from the main substrate 190 to the touch substrate 320 and transferring corresponding register data from the touch substrate 320 to the main substrate 190.

After the step S14, the main substrate 190 determines whether the register value transferred from the touch substrate 320 is a default value (S15).

Here, the default value means the initial value of the register of the touch substrate 320 basically even if the register setting of the touch substrate 320 is not set in the main substrate 190.

In the present invention, in the case of the touch substrate 320, since there is no non-volatile memory, when reset, registers do not remember the previous value and have a default value.

Thereafter, in step S15, when the register value transmitted from the touch substrate 320 is a default value, the main substrate 190 determines that the touch substrate 320 has been reset and registers it with the touch substrate 320. Reset the value (S16)

After step S16, the process goes to step S12.

On the other hand, in step S15, if the register value transmitted from the touch substrate 320 is not the default value, the main substrate 190 determines that the touch substrate 320 has not been reset and proceeds to step S12. Goes.

For reference, when the register value is not reset from the main substrate 190 to the touch substrate 320 while the touch substrate 320 is reset, the touch substrate 320 having no nonvolatile memory device malfunctions. do.

As another example, the step S15 may be performed by determining whether the register value of the touch substrate 320 read from the main substrate 190 is a register value set in the touch substrate in step S11.

In addition, in step S16, when the register value of the touch substrate 320 read from the main substrate 190 is different from the register value set in the touch substrate in step S11, the touch substrate 320 in the main substrate 190 It may be determined that the reset has been performed, and the register value may be reset with the touch substrate 320.

As described above, according to the present invention, while the main substrate and the touch substrate communicate, the register value of the touch substrate is periodically read, and the connection between the main substrate fixed to the main body and the touch substrate rotating together with the water discharge module is temporarily Even if it is disconnected and connected, it has the effect of immediately detecting it and resetting the register value in the default touch substrate.

According to the present invention, even if the touch substrate is reset, it is possible to immediately reset the register value on the touch substrate, thereby preventing a touch malfunction of the touch device.

As described above, the present invention has been described with reference to the exemplified drawings, but the present invention is not limited by the examples and drawings disclosed in the present specification, and can be varied by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that modifications can be made.
