Description

Water purifying device {WATER PURIFYING DEVICE}

The present invention relates to a water purification device excellent in sterilization effect.

As people's awareness of health increases, interest in food, especially water, which accounts for 70% of the human body, is increasing. In the past, people ingested water through tap or bottled water, but recently, people ingest water through water purifiers not only in offices but also in homes.

According to the announcement of the Ministry of Environment in 2018, the number of water purifiers distributed in Korea exceeded 7 million, and in particular, the penetration rate of household water purifiers increased significantly, confirming that the penetration rate of domestic water purifiers in all homes and offices exceeded 60%.

Conventionally, a water purifying device configured to filter and discharge water while storing water in a water tank has been used. Recently, when a user operates the water purifying device while directly connected to a water supply unit such as water without a water tank, water is supplied and at the same time. The so-called'direct water purifier' that is filtered and discharged is increasingly used.

Direct water purifiers were first launched in 2015 and have increased from 300,000 units to 500,000 units in 2016, 1 million units in 2017, and 1.5 million units in 2018 last year. In particular, the market share of direct water purifiers is close to 60% of the total water purifier market. This is because water purifiers used in existing offices are increasingly used for home use, so it is judged that the market share of direct water purifiers is increasing because only the filter can be replaced due to its small volume and simple configuration.

However, the direct water purifier has the following problems.

First, the purity of raw water varies according to the performance of the filter, and when the filter is used for a certain period of time, there is a problem that the water purification performance of the raw water is deteriorated due to contamination of the filter.

Second, in the case of a water purifier using only a filter, some organic matters that could not be filtered by the filter are dissolved in the filtered raw water, so there is a problem that it is insufficient for the user to safely consume it as drinking water.

Third, as the filter is contaminated during the water purification process, there is a problem that maintenance costs are excessively wasted because the filter needs to be frequently replaced, and the user suffers inconvenience for the filter replacement.

Fourth, when the water purifier is turned on during water purification, standby power is increased because the filter or sterilization device is always operated, and thus the life of the water purifier is shortened, and maintenance costs are excessively wasted.

Fifth, in the case of sterilizing water with OH radicals through ozone and ultraviolet rays used in a general water storage tank, there is a problem that the maintenance cost is excessively wasted due to high power used for ozone and ultraviolet rays.

In order to solve the above problems, an object of the present invention is to provide a water purifying apparatus that supplies purified drinking water obtained by filtration through a filter unit and sterilization through a sterilization unit. It is not limited to the above-described technical problem, and another technical problem may be derived from the following description.

In addition, a pressure sensor disposed between the filter unit and the sterilization unit may further include a pressure sensor measuring a water pressure value of raw water flowing through the flow path, and the control unit stores a preset pressure value measured by the pressure sensor. Compared with the value, when the measured pressure value exceeds the set pressure value, the illuminance value of the light emitting unit is increased above the first reference illuminance value, and when the flow pressure value is less than the set pressure value, the illuminance value of the light emitting unit is adjusted It is characterized in that it is lower than the first reference illuminance value.

In addition, it may further include a dissolved oxygen measuring sensor disposed in the water tank to measure the amount of dissolved oxygen in drinking water, the control unit by comparing the measured oxygen amount measured by the dissolved oxygen measuring sensor and the stored set oxygen amount, the measured oxygen amount When the amount of oxygen is less than the set amount, the illuminance value of the light-emitting unit is higher than the second reference illuminance value, and the ozone generation amount of the ozone generating unit is increased.

In addition, the filter unit may include a filter unit for filtering foreign substances in the drinking water while passing through the drinking water introduced from the inlet; A filter head disposed on one side of the filter unit to fix the filter unit; And a filter sterilization unit coupled to pass through the filter head and generating ultraviolet rays for sterilizing the filter unit.

In addition, the filter sterilization unit is characterized in that it is detachably coupled to the filter head.

According to the water purifying apparatus according to the embodiment of the present invention having the configuration as described above has the following effects.

First, when the filter unit is used, since there is a filter sterilization unit that sterilizes the filter in real time, the period of use of the filter is extended, thereby reducing the cost of replacing the filter or the consumption of labor for the replacement.

Second, since the raw water is primarily filtered through the filter unit, and the raw water filtered secondarily through the sterilization unit is sterilized and supplied as drinking water, there is an effect of providing drinking water that the user can safely consume.

Third, since the filter sterilization unit or the sterilization unit operates only when raw water flows inside, there is an effect of reducing standby power and saving management costs.

Fourth, as the reflector is attached to the tank tank, raw water can be efficiently sterilized even if the amount of ultraviolet rays and ozone supplied from the sterilizing unit is small, thereby reducing management costs.

In detail, the filter sterilization unit 123 may include a UV LED or a UV lamp, and the ultraviolet rays generated from the filter sterilization unit 123 may be irradiated to the filter unit 121 through the coupling hole. . There is an effect of sterilizing the filter unit 121 by the irradiated ultraviolet rays.

The sterilization unit 130 is a means for sterilizing the raw water filtered through the filter unit 120 and increasing the amount of dissolved oxygen inside. In detail, the sterilization unit 130 sterilizes various microorganisms and bacteria contained in the raw water filtered from the filter unit 120 and at the same time increases the amount of dissolved oxygen dissolved in the raw water to provide beneficial drinking water to the user. have.

A space 131a may be provided. For example, the water tank 131 may be a box-shaped tank with an open top surface.

The ultraviolet ray generator 132 is a means for generating ultraviolet rays by being disposed inside the water tank 131, in detail, in the storage space 131a. In detail, the ultraviolet generator 132 may include a light emitting part 132a that irradiates ultraviolet rays and a cover part 132b made of a transparent material that covers an outer surface of the light emitting part 132a.

The light emitting unit 132a may include an ultraviolet LED or a lamp, and is preferably a means capable of stably irradiating ultraviolet rays with an ultraviolet LED at low power.

In addition, the cover part 132b may be made of a transparent material so that the ultraviolet ray scanning unit can directly irradiate ultraviolet rays to the filtered raw water received in the storage space 131a. For example, the cover part 132b may be made of quartz, that is, glass.

The ozone generator 133 is a means for generating ozone by being disposed inside the water tank 131, in detail, in the storage space 131a. In detail, the ozone generator 133 may be a Siemens type ozone tube, a Brodie type ozone tube, or a Siemens-Halske type ozone tube. In general, there is no limitation on this as long as it is a means capable of generating ozone in water.

In particular, the ozone generator 133 may generate a small amount of ozone, and as an example, the amount of ozone generated may be less than 0.1 ppm. This is an amount within a range in which ozone does not affect the human body, and if the ozone amount exceeds 0.1 ppm, there is a problem that safety may be deteriorated.

The ultraviolet ray generating unit 132 and the ozone generating unit 133 irradiate ultraviolet rays and ozone from the filtered raw water contained in the storage space 131a of the water tank 131, respectively, and the ozone is dissolved in the raw water and converted into dissolved ozone. It can be changed.

The dissolved ozone is photo-decomposed by ultraviolet rays to generate hydrogen peroxide water as an intermediate material as an initial result, and the generated hydrogen peroxide water decomposes dissolved ozone at a high speed and generates OH radicals.

In this case, the reflective surface 134b may be formed in a pyramid shape, and may protrude to a greater height toward the center. As the reflective surface 134b has a three-dimensional shape having an angle rather than a planar shape, there is an effect that ultraviolet rays can be reflected to various locations of the storage space 131a.

One or more reflective surfaces 134b may be disposed on the inner surface of the water tank 131, preferably in plurality. Accordingly, there is an effect that ultraviolet rays can be reflected and irradiated to all of the internal storage spaces 131a of the water tank tank 131, thereby increasing the sterilization efficiency of the filtered raw water stored in the water tank tank 131. .

That is, the sterilization unit 130 may store the raw water filtered from the pump unit in the water tank tank 131 for a certain period of time, and the ultraviolet ray generation unit and the ozone generation unit 133 Can occur. In addition, even if the illumination of the UV rays is low, all of the UV rays can be irradiated to the raw water inside the tank tank 131 by the reflecting unit 134, and thus, the filtered raw water can be efficiently sterilized even with low power. There is an effect.

The supply method of the outlet 140 may include a manual valve or an electromagnetic valve, and there is no limitation on the structure as long as it can supply drinking water.

Hereinafter, a configuration for controlling the filter unit 120 and the sterilization unit 130 in the water purifying apparatus 100 according to an embodiment of the present invention will be described. The water purifying apparatus 100 according to an embodiment of the present invention is capable of measuring the water pressure of raw water flowing into the filter unit 120 and the amount of dissolved oxygen in the raw water accommodated in the storage space 131a inside the water tank tank 131. The sensing unit 150 may include a control unit 160 capable of controlling the operation of the filter unit 120 and the sterilization unit 130.

The sensing unit 150 includes a pressure sensor 151 disposed between the filter unit 120 and the water tank 131 to measure the water pressure of raw water flowing into the filter unit 120, and the water tank It may include a dissolved oxygen measuring sensor 152 disposed under the tank 131 to measure the dissolved oxygen of the raw water accommodated in the storage space (131a).

The pressure sensor 151 may be disposed in a flow path flowing from the filter unit 120 to the water tank tank 131, and can measure a water pressure value of filtered raw water flowing in the flow path, and the measured water pressure below The value is defined as'measured pressure value'. In detail, when the user is not using the water purifier 100, the measured pressure value can be measured very low because the raw water remains between the filter and the water tank 131 without flowing. In the case of using the device 100, since raw water flows between the filter and the water tank 131, the measured pressure value can be measured high.

The dissolved oxygen measurement sensor 152 is disposed in the storage space 131a of the water tank tank 131, in detail, the lower surface of the water tank tank 131 to measure the amount of dissolved oxygen dissolved in filtered and sterilized raw water received therein. have. For example, the dissolved oxygen measurement sensor 152 may include a dissolved oxygen (DO) sensor or an Oxidation Reduction Potential (ORP) sensor. Below, the amount of dissolved oxygen measured by the dissolved oxygen measuring sensor 152 is defined as'measured oxygen amount'.

The control unit 160 filters the filter based on the measured value measured by the sensing unit 150, the measured pressure value measured by the pressure sensor 151 in detail, and the measured oxygen amount measured by the dissolved oxygen measuring sensor 152. The operation of the unit 120 and the sterilization unit 130 may be controlled.

In the control unit 160, an average pressure value of a pressure value when water does not flow and a pressure value when water flows in the flow path between the filter unit 120 and the water tank 131 by operating the water purification device 100 Has been saved. The stored average pressure value is defined as the'set pressure value'.

In addition, the control unit 160 may store a reference value of the amount of dissolved oxygen of the raw water stored in the water tank 131. The reference value of the stored dissolved oxygen amount is defined as a'set oxygen amount', and as an example, the set oxygen amount may be 15 ppm.

Below, the first operation of the control unit 160 controlling the filter unit 120 and the sterilization unit 130 according to whether raw water flows through the water purifying device 100, that is, whether pressure is measured in the flow path. Explain about. 4 is a flowchart showing a first operation of the water purifying apparatus 100 according to an embodiment of the present invention.

4, when the pressure sensor 151 measures the pressure of raw water (S110), the controller 160 compares the stored set pressure value with the measured pressure value measured by the pressure sensor 151 (S120). )can do. As a result of the comparison, when the measured pressure value is less than the set pressure value, that is, when raw water does not flow because the water purifying device 100 is not operating, the ultraviolet irradiance irradiated from the filter sterilization unit 123 of the filter unit 120 It may be lower than the first reference illuminance value (S141). Here, the first reference illuminance value is an illuminance value of ultraviolet rays irradiated by the filter sterilization unit 123 for sterilization.

Conversely, when the measured pressure value exceeds the set pressure value, that is, when the water purifying device 100 is operating, the ultraviolet irradiance irradiated from the filter sterilization unit 123 of the filter unit 120 is first It can be higher than the reference illuminance value. (S151)

That is, by operating the filter sterilization unit 123 of the filter unit 120 only when the water purifying device 100 operates and raw water flows inside, the filter unit 121 and the filtered raw water are simultaneously sterilized with ultraviolet rays. There is an effect that can be done. Conversely, when the water purifier 100 is not operated, there is an effect of lowering the power consumption in the standby state by lowering the UV illuminance value of the filter sterilization unit 123.

Similarly, the control unit 160 compares the stored set pressure value with the measured pressure value measured by the pressure sensor 151 (S130), and when the measured pressure value is less than the set pressure value, that is, the water purifying device 100 When the raw water does not flow because it is not operated, the ultraviolet irradiance of the ultraviolet ray generator 132 of the sterilization unit 130 is lowered than the second reference illuminance value (S142) and the ozone generation amount of the ozone generator 133 is reduced. It may be lower than the first reference ozone amount (S143). Here, the second reference illuminance value and the first reference ozone amount are the minimum illuminance value and the minimum amount of ozone generated by the ultraviolet ray generator 132 and the ozone generator 133 for sterilization.

Conversely, when the measured pressure value exceeds the set pressure value, that is, when the water purifying device 100 is operating, the ultraviolet irradiance irradiated from the ultraviolet ray generating unit 132 of the sterilizing unit 130 is second At the same time as raising the reference illuminance value (S152), the ozone generation amount of the ozone generator 133 may be higher than the first reference ozone amount (S153).

That is, the filter sterilization unit 123 of the filter unit 120 is operated only when the water purifying device 100 operates and raw water flows therein, or the ultraviolet ray generating unit 132 of the sterilization unit 130 and By operating the ozone generator 133, there is an effect of increasing the amount of dissolved oxygen while sterilizing the filter unit 121 and the filtered raw water in real time with ultraviolet rays in real time while the water purifying device 100 is operating. Conversely, when the water purifying device 100 does not operate, by controlling the operation of the filter sterilization unit 123, the ultraviolet ray generation unit 132, and the ozone generation unit 133, the ultraviolet irradiance value or the amount of ozone oxygen is reduced. , It has the effect of reducing power consumption.

Hereinafter, a second operation of controlling the sterilization unit 130 according to the amount of dissolved oxygen dissolved in the filtered raw water in the storage space 131a of the water tank 131 by the control unit 160 will be described. 5 is a flowchart showing a second operation of the water purifying apparatus 100 according to an embodiment of the present invention.

5, when the dissolved oxygen measuring sensor 152 measures the amount of dissolved oxygen in the raw water inside the tank tank (S220), the control unit 160 determines the stored set oxygen amount and the dissolved oxygen measuring sensor 152. When the measured oxygen amount is compared (S230), and the measured oxygen amount is less than the set oxygen amount, that is, when the amount of dissolved oxygen in the raw water accommodated in the storage space 131a of the water tank tank 131 is lower than the reference value and is insufficient, the filter unit 120 The ultraviolet irradiance irradiated from the filter sterilization unit 123 of may be higher than the third reference illuminance value (S241). In addition, at the same time, the control unit 160 controls the ozone generating unit 133 to increase the amount of ozone generated by the ozone generating unit 133 higher than the second reference ozone amount (S242). Here, the third reference illuminance value and the second reference ozone amount are the minimum illuminance values of ultraviolet rays that can be generated by the ultraviolet ray generator 132 and the ozone generator 133 in order to increase the amount of dissolved oxygen than the set amount of oxygen. This is the minimum production amount. Through this, the amount of dissolved oxygen in the raw water accommodated in the water tank tank 131 may be increased.

Conversely, when the measured oxygen amount is greater than the set oxygen amount, that is, when the dissolved oxygen amount of the raw water accommodated in the storage space 131a of the water tank 131 is greater than the reference value, the filter unit 120 The ultraviolet irradiance irradiated from the filter sterilization unit 123 may be lower than the third reference illuminance value (S251). In addition, at the same time, the control unit 160 controls the ozone generating unit 133 to lower the amount of ozone generated by the ozone generating unit 133 than the second reference ozone amount (S252). Through this, there is an effect of lowering power consumption while maintaining the amount of dissolved oxygen in the raw water accommodated in the water tank tank 131.
