The present invention relates to a filter replacement time notification device for a water purifier capable of maintaining a constant filter replacement time.

In recent years, as the water pollution caused by industrial development has become serious, distrust in tap water has increased, and recently, purified water with a water purifier is used as drinking water or commercially available bottled water as drinking water.

The water purifier is made to remove heavy metals and other harmful substances contained in the raw water through the process of sedimentation, filtration and sterilization of raw water, such as tap water. It is also widely used for cleaning or medical use of electronic components.

Such a water purifier is manufactured and used in various kinds according to the water purification method, the structure of a conventional water purifier is a plurality of filter members for removing and purifying the foreign matter contained in the raw water supplied through the water supply pipe, and the filter member sequentially A storage tank for storing purified water while passing through, a hot water tank and a cold water tank for receiving and supplying purified water from the purified water storage tank, respectively, and for discharging water contained in the hot water tank and the cold water tank to the outside. A plurality of discharge cocks are provided.

The filter member typically has a structure in which the sedimentation filter, the pretreatment carbon filter, the membrane filter, and the aftertreatment carbon filter are sequentially connected. Heavy metals and other harmful substances are removed.

If the water purifier is used for a certain period of time, the purifying capacity of the filter member is lowered. Therefore, the filter member needs to be replaced with a new one. A method of cumulatively calculating the usage time of and replacing the filter every predetermined period is used.

However, in such a conventional filter replacement method, the method of measuring the amount of raw water that has passed through the filter and replacing the filter includes the amount of raw water that has passed through the filter member even when the water purifier is not used for a long time due to travel or the like. If the filter is less than or equal to, there is a high possibility of drinking the decayed or bacteria-grown water in the filter member, accumulating the use time of the water purifier, and replacing the filter member every predetermined period of time. It is difficult to remember this correctly because it must be remembered and replaced, which makes it difficult to know exactly when to replace the filter of the water purifier.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to accumulate the respective filter member usage time provided in the water purifier to generate a preliminary signal when the replacement time is approaching, replacement time The present invention provides a filter replacement time notification method of a water purifier capable of generating a replacement signal and always maintaining a constant filter replacement time.

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

1 is a view showing the configuration of a water purifier provided with a filter replacement time notification device of the water purifier according to the present invention, wherein the filter replacement time notification device of the present invention accumulates and stores the installed time of the filter member 2 installed in the water purifier. A memory section 4,

A control unit 6 which stores each filter life time and compares each accumulated time stored in the memory unit 4 with the filter life time to determine an exchange time of the filter member 2;

Under the control of the control unit 6, the forecast display unit 8 for notifying in advance that the replacement time of the filter member 2 is approaching when the cumulative time of the memory unit 4 reaches a predetermined period of the life time;

The exchange display unit 10 for informing the exchange of the filter member 2 when the cumulative time of the memory unit 4 is equal to the filter life time under the control of the control unit 6;

And a reset switch 12 for replacing the filter member 2 installed in the water purifier and reducing the filter member usage time stored in the memory unit 4 to an initial value.

The filter member 2 is typically connected to the sedimentation filter (2a), the pretreatment carbon filter (2b), the membrane filter (2c), the post-treatment carbon filter (2d) is first connected to the raw water from the water supply pipe sequentially When the raw water, such as tap water, passes through the filter member 2, it is configured to remove heavy metals and other harmful substances contained in the raw water through a process of precipitation, filtration, sterilization, and the like.

The precipitation filter (2a) filters the soil, sand or suspended matter contained in the raw water, the pretreated carbon filter (2b) serves to remove residual chlorine contained in the raw water, the membrane filter (2c) is heavy metal It filters out various harmful substances such as carcinogens and chemicals, and passes only pure water, dissolved oxygen and very small amount of minerals. The post-processing carbon filter (2d) removes fine particulate matter and various bacteria. Plays a role.

The memory unit 4 accumulates and stores the installed time of the filter member 2 installed in the water purifier. The accumulated time is based on a system oscillation frequency that is commonly used when counting seconds, minutes, hours, and days. The cumulative time after each filter 2a, 2b, 2c and 2d is respectively calculated.

The control unit 6 stores the life time of each filter 2a, 2b, 2c, and 2d. In general, the life time of the precipitation filter 2a and the pretreated carbon filter 2b is 6 months, and the membrane filter. (2c) is stored for 18 months, and the post-treatment carbon filter (2d) has a life time of 12 months.

The forecast display section 8, for example, installs an LED lamp on the front or side of the water purifier main body, and changes the color of the lamp from the normal state to another color (for example, from green to yellow) to the control unit 6 By allowing the control to be able to inform in advance that the approaching of the filter member (2) is approaching.

The exchange display unit 10 is installed on the front or side of the water purifier main body of a different color than the lamp color of the forecast display unit 8, and configured to flash at regular intervals by the control unit 6 to filter the user of the water purifier. It is to inform that it is time to replace the member 2.

The forecast display section 8 and the exchange display section 10 may constitute independent display sections independently of each other so as to display the states of the filters 2a, 2b, 2c, and 2d.

As shown in Figure 2, the operation of the filter replacement time notification device of the water purifier of the present invention, when using the water purifier, each filter constituting the filter member 2 (2a) (2b) (2c) (2d) Time is accumulated and stored in the memory unit 4.

When the cumulative time of one of the filters of the memory unit 4 approaches a certain period of the life time (S1), the control unit 6 checks outside the water purifier to notify the user in advance of the replacement time of the filter. The forecast display unit 8 made of LED lamps is turned on (S2).

The operation of the forecast display unit 8 assumes, for example, that the life time of the precipitation filter 2a is 6 months, and the usage time of the precipitation filter 2a is 5 when this time is stored in the control unit 6. When the month is reached, the forecast display unit 8 may be turned on in comparison with the life time of the sedimentation filter stored in the control unit 6. Other filters, pretreatment carbon filter 2b, membrane filter 2c, and post-treatment carbon, may be used. The filter 2d can also operate the forecast display section 8 by using the filter for a certain period in the same manner.

In the above description, the forecast display unit 8 is operated one month before the filter's life time, but the period can be shortened or extended.

When the forecast display unit 8 is turned on as described above, the water purifier user has time to prepare a new filter by recognizing that the filter replacement time is near, and in this state, the sedimentation filter accumulated in the memory 4 is continuously used. When the filter usage time of 2a) reaches the filter life time stored in the control section 6 (S3), the forecast display section 8 is turned off and the exchange display section 10 is operated (S4).

The replacement display unit 10 is configured to blink at regular time intervals while being made of a lamp of a different color from the lamp color of the forecast display unit 8, so that the water purifier user can be surely aware of the replacement time of the filter member 2. It is.

The flashing of the replacement display unit 10 continues until the precipitation filter 2a is replaced, and after replacing the precipitation filter 2a with a new filter (S5), pressing the reset switch 12, the replacement display unit 10 While the blinking of the light is stopped and the lamp color of the initial state and the filter member stored in the memory unit 4 is reduced to the initial value (S6).

In the above, the operation of the filter replacement filter device is explained by using the precipitation filter 2a as an example. However, the pretreatment carbon filter 2b, the membrane filter 2c, and the aftertreatment carbon filter 2d can also notify the filter replacement time by the same operation. Can be.

As described above, the filter replacement time notification device of the water purifier according to the present invention generates a prediction signal indicating that the replacement time of the filter is approaching a certain period before the service life of the filter is approaching, thereby allowing the user to prepare a time for preparing the filter. In addition, when the filter is replaced, a replacement signal is generated so that the user can always recognize and replace the water filter at the time of replacement, thereby preventing the drinking of unpurified water by using a deteriorated filter.
