The present invention relates to a method of operating a water purifier system through a pressure switch, and more particularly, to a method of operating a water purifier system through a pressure switch which can stably operate the water purifier by preventing malfunction due to electrical noise.

As a conventional water purifier, it is presented in the publication of Korean Utility Model Registration No. 20-0327037.

Water purifiers that provide alkaline ionized and acidic water by electrolyzing the purified water of existing water purifiers have been proposed. Such a water purifier is called an ion water purifier. As a conventional water purifier, the ion water purifier will be described as an example.

However, even in the purified water, while stored in various reservoirs, the scale is generated, there is a problem that bacteria grow. In addition, in order to be provided with a desired number of functions, there is a problem in that a drain manifold must be provided as described above, or a cock must be provided with each functional water.

In addition, it has a system that is discharged by a hydraulic pressure difference when the pressure drops simply as a mechanical system, but in the case of a refrigerant tank type water purifier, solenoid valves according to various flow paths are separately configured to control various solenoid valves. have.

The present invention has been made to solve the above problems, and an object thereof is to provide a water purifier system through a pressure switch that can be operated stably by preventing a malfunction caused by electrical noise.

Water purifier system operation method through the pressure switch of the present invention for achieving the above object is a pressure sensing step of detecting the purified water pressure of the front end of the cock through the pressure switch, and determining whether or not the high pressure by receiving the detected signal And, when the pressure is low pressure is characterized in that it comprises a step of switching the water purifier to the water discharge state, and when the pressure is high pressure to stop the water discharge.

According to this configuration, it is possible to detect the pressure of the front end of the cock through the pressure switch to automatically operate the water purifier.

Furthermore, before the water purifier is switched to the water discharge state, the method may further include determining whether the low pressure is maintained for a predetermined time or giving a delay time, thereby preventing the water purifier from malfunctioning due to electrical noise. Can work.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.

3 is a block diagram of a water purifier according to a preferred embodiment of the present invention.

As shown in Fig. 3, the water purifier of the present embodiment includes a filter 11 for filtration and purification of raw water, a solenoid valve 61 and 62 for controlling the flow of purified water passing through the filter 11, and Coke 70 through which the purified water passing through the solenoid valves 61 and 62 is discharged, a pressure switch 40 disposed in a flow path between the solenoid valves 61 and 62 and the cock 70, and the pressure switch. And a control unit (not shown) for sending the signal of 40 to the solenoid valves 61 and 62.

The water supply solenoid valve 61 provided in front of the filter 11 controls the flow of purified water flowing into the filter 11.

In order to further provide alkaline ionized water and acidic water, the water purifier may be provided with an electrolytic cell 13 which electrolyzes the purified water introduced from the filter 11 to generate acidic water and alkaline ionized water.

The electrolytic cell solenoid valve 62 provided at the front end of the electrolytic cell 13 controls the flow of purified water flowing into the electrolytic cell 13.

Furthermore, it is preferable to provide the alkali cold water by cooling the alkali ion water generated from the electrolytic cell 13 by providing a refrigerant tank type cooling means.

A pressure switch is provided on the pipe 94 in front of the cock 70 to detect a pressure value that is changed due to the opening and closing of the cock 70.

The pressure switch 40 is preferably a low pressure cutoff switch (LPS).

For the specific actuation mechanism for the low pressure shut-off switch (LPS), reference is made to the publication of the reference number 20-0294986.

The low pressure shut-off switch (LPS) switches by using low pressure of the liquid, and more specifically, it is installed in the middle of the flow of liquid to operate the switch using the pressure of the flowing liquid to operate a flow-related device such as a pump and a solenoid valve. By controlling automatically the flow of the liquid in accordance with the pressure set in the low pressure cut-off switch (LPS).

In the water purifier provided with a number of functions, when the user presses a button of the desired number of functions, the controller may wait for the on / off of the solenoid valve concerned.

At this time, when the coke 70 is opened and the pressure in the pipe is lowered, a signal enters the pressure switch 40 and the signal is transmitted to the related solenoid in the waiting state, while opening the solenoid and withdrawing the functional water accordingly.

When the cock 70 is closed and the signal of the pressure switch 40 is cut off, the associated solenoid valve which is open is closed and the supply of the functional water is stopped.

Thus, the water purifier system is automatically and stably operated by opening and closing the solenoid valve based on the control unit receiving the on / off signal by the pressure switch 40.

Hereinafter, the operation method of the present embodiment having the above-described configuration will be described.

2 is a flowchart of a method of operating a water purifier system through a pressure switch according to a preferred embodiment of the present invention.

As shown in Figure 2, the water purifier system operation method through the pressure switch 40 is a pressure sensing step (S1) for detecting the purified water pressure of the front end of the cock 70 through the pressure switch 40, the detected signal Determining whether or not the high pressure is received (S3), and in the case of low pressure, the water purifier is switched to the water exit state, and in the case of high pressure comprises the step of stopping the water discharge (S5).

The pressure sensing step S1 detects the hydrostatic pressure of the front end of the cock 70 through the pressure switch 40.

Here, the pressure of the purified water is provided with a pressure switch 40 on the flow path in front of the cock 70, to detect the pressure value changed due to the opening and closing of the cock 70.

In response to the detected signal, it is determined whether or not the pressure is higher than a predetermined pressure reference value (S3). When the pressure is high, the water is stopped to maintain the system in the water outlet stop state or water outlet standby state.

In the determining step (S3), when the pressure switch 40 transmits only the on / off signal, it may be determined whether the high pressure or the low pressure is only on / off itself, and the pressure switch 40 transmits various pressure values. In the predetermined pressure reference value can be set in advance to determine whether or not high pressure.

On the other hand, in the case of detecting the pressure by the contact detachment and detachment of the mechanical pressure switch 40 as described above may cause a malfunction of the water purifier by the electrical noise generated when the contact detachment.

Therefore, in order to prevent such a malfunction, a step of giving a delay time when it is determined that the pressure is low in the step (S3) of initially determining whether the low pressure or high pressure, the water purifier is switched to the water exit state after the delay time It is preferable to operate the respective operation mechanisms (solenoid valves 61, 62, electrolytic cell 13, etc.) related to the water discharge (S13), and to stop the water discharge when the delay time has not passed.

Here, the delay time is a suitable time (hundreds of msec) calculated by experiment or the like.

On the contrary, in order to prevent such a malfunction, when the pressure is determined to be low in the step S3 of initially determining whether the low pressure is low, the low pressure may include determining whether the low pressure is maintained for a predetermined time (S7). When the water purifier is maintained, the water purifier is switched to the water discharge state (S9), and each of the operating mechanisms (solenoid valves 61 and 62, the electrolyzer 13, etc.) related to the water discharge is operated (S13). It is preferable to stop (S11).

Here, the predetermined time is a suitable time calculated by experiment or the like.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified or modified within the scope of the invention without departing from the spirit and scope of the invention described in the claims below.
