Therefore, in recent years, a direct water purifier has been widely used instead of the water tank type water purifier. That is, the water introduced immediately without the separate water tank is immediately purified and provided to the user.
However, since the water tank type water purifier extracts the water stored in the water tank, the water pressure is always maintained within a certain range, so that the water is extracted for a predetermined period of time The amount of water can be provided.
On the other hand, in the case of the direct water-purifying device, the water pressure of the raw water may be different at each installation site, and the amount of water extracted per unit time differs depending on the water pressure, so that it is difficult to extract a fixed amount. Particularly, when a failure or the like occurs in the flow rate sensor for measuring the amount of water to be extracted, it is difficult to quantitatively extract it.

Hereinafter, a quantitative extracting apparatus according to an embodiment of the present invention will be described with reference to FIG.
The quantitative extraction apparatus 100 can control the flow rate of the fluid to be supplied and supply the fluid at a predetermined supply flow rate. The quantitative extraction apparatus 100 may be applied to any apparatus that needs to supply a certain amount of fluid, and may be applied to a direct water purifier as shown in FIG.
When the quantitative extraction apparatus 100 is applied to a direct water purifier, the fluid for controlling the flow rate of the quantitative extraction apparatus 100 may be at least one of purified water, hot water and cold water generated by the direct water purifier. That is, the quantitative extraction device can control to discharge the purified water, the hot water, and the cold water discharged by the water purifier by the preset supply flow rates, respectively.
Specifically, the direct water-purifying device can generate purified water by filtering the incoming raw water with the filter portion (f), and then supplies the purified water to the heater portion (h) to generate hot water or supply it to the cooling portion Thereby generating cold water. Here, the generated purified water, hot water, and cold water may be discharged to the outside through the

However, the quantitative extraction using the target supply time may be performed temporarily until maintenance such as repair or replacement of the
Here, the target supply time may vary depending on the installation area in which the fluid generating device, i.e., direct water purifier, is installed. That is, when the direct-acting water purifier is installed in a low-lying zone, the tap water used as the raw water may have a high water pressure and a high flow rate. On the contrary, when the water purifier is installed at a high altitude, It can be low and low. In addition, there may be various cases such as when ground water is used as raw water. Therefore, installation conditions such as hydraulic pressure and flow rate of raw water may be changed depending on the installation area of the water purifier.
Since the installation conditions such as the water pressure and the flow rate of the raw water ultimately affect the flow velocity and the water pressure of the fluid discharged from the direct water-purifying device, the predetermined target supply time may be set in consideration of the installation conditions. Among various factors determined depending on installation conditions of the water purifier, in particular, the flow rate and water pressure of the raw water may be important.

Referring to FIG. 3, a fluid supply step S10, a supply flow measuring step S20, a supply time measuring step S30, a supply stop step S40, and an alarm output step S50 may be included.
Hereinafter, a quantitative extraction method according to an embodiment of the present invention will be described with reference to FIG.
A quantitative extraction method according to an embodiment of the present invention relates to a method of controlling a flow rate of a supplied fluid to provide a flow rate by a predetermined supply flow rate. Therefore, the quantitative extraction method can be applied at any time when it is necessary to supply a certain amount of fluid, and in particular, the quantitative extraction method can be applied to a direct water purifier. The direct water purifier does not include a separate water tank. When the user's request for watering is input, the supply of raw water to the filter unit is started, and the purified water generated by the filtering unit is directly supplied to the user through the supply valve . In addition, the water purifier may further include a heater unit and a cooling unit. The heater unit and the cooling unit may be used to heat or cool the purified water, respectively, to generate hot water or cold water. Therefore, the above-described quantitative extraction method can be applied not only to the above constants but also to hot water or cold water.
First, the fluid supply step (S10) can open the supply valve and discharge the fluid through the supply valve. An outflow request for the fluid may be inputted to the direct water purifier or the like for generating the fluid, and the supply valve may be opened correspondingly.
When the supply valve is opened, the process may proceed to the supply flow measuring step (S20). The supply flow rate measuring step (S20) can measure the flow rate of the fluid discharged from the supply valve by using the flow rate sensor, and calculate the supply flow rate of the fluid. Here, the flow rate sensor may include a rotating body rotated by a fluid flowing through the flow channel, and the flow rate of the fluid may be determined from the rotating speed of the rotating body. Therefore, it is possible to calculate the supply flow rate of the fluid discharged from the supply valve by using the flow rate.
As shown in FIG. 3, when the supply valve is opened, the supply time measurement step S30 may be performed together with the supply flow rate measurement step S20. That is, the supply time measuring step S30 may start counting the supply time from when the supply valve is opened, and measure the supply time at which the fluid is supplied. Thereafter, it is possible to determine whether the supply flow rate measured using the flow sensor corresponds to a predetermined target flow rate or whether the counted supply time reaches a predetermined target supply time.
When the supply flow rate measured using the flow sensor corresponds to a predetermined target flow rate or when the counted supply time reaches a predetermined target supply time, the supply valve is closed in accordance with the supply stop step (S40) Can be stopped.
In general, the flow sensor can be used to provide a fluid at a predetermined target flow rate, and in this case, a fluid with an accurate target flow rate can be provided to the user. However, when the flow sensor fails or the flow rate of the flowing fluid exceeds the measurement range of the flow rate sensor, the flow rate sensor may fail to provide the flow rate of the target flow rate. That is, when a failure or the like occurs in the flow sensor, the fluid continues to be discharged to supply the fluid at a predetermined target flow rate, which may cause user inconvenience, and there is a risk of image generation. Therefore, when the failure of the flow sensor occurs, the supply valve can be closed to prevent the risk.
However, according to an embodiment of the present invention, even if a failure or the like occurs in the flow rate sensor, the user can be provided with a fluid having a predetermined target flow rate. That is, when the counted supply time reaches a predetermined target supply time, the supply of the fluid can be performed in such a manner as to close the supply valve. At this time, the flow rate of the fluid discharged during the target supply time and the target flow rate may have some errors. However, it is possible to provide the user with a fluid amount close to the target flow rate in spite of the failure of the flow sensor, so that the convenience of the user can be further improved.
Here, the target supply time may be calculated using the fluid generator installation condition for generating the fluid. That is, it is possible to calculate the time required for the fluid to be discharged by the target flow rate using the installing condition of the water purifier, and set the calculated time as the target supply time. Particularly, it is possible to calculate the time required for the fluid to be discharged by the target flow rate using the flow rate and the water pressure of the raw water supplied to the direct water-purifying device from among the installation conditions, and can set the target supply time.
In the
Therefore, by using the alarm output step S50, the user can be informed that there is an abnormality in the flow rate sensor. Specifically, the alarm output step (S50) may include an alarm to allow the user to recognize that the flow sensor is abnormal through a sense of sight such as sight and hearing. For example, you can output a warning sound or flash a warning light. Or a water purifier or the like may be displayed on the display unit so that the user can visually recognize the abnormality of the flow sensor. A user who has detected an abnormality in the flow sensor can take measures against the abnormality of the flow sensor through a customer center or the like. A predetermined amount of fluid can be supplied to the user by using the arrival time of the target supply time until the failure or the like of the flow sensor is corrected.
The present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
