Description

Water Purifier {Purifier}

The present invention relates to a water purifier. More specifically, the heater operates only when hot water is used through the instantaneous hot water bath, thereby reducing energy consumption by preventing the heater from being repeatedly operated at a predetermined temperature range, and independently purifying the cold water tank and the instantaneous hot water tank. The present invention relates to a water purifier that prevents bacterial contamination by air contact and at the same time prevents hot water backflow structurally, thereby improving cooling efficiency for cold water, thereby reducing energy associated with driving a cooler.

Recently, due to the rapid industrial development, environmental pollution is getting worse. Among these, water pollution reaches a serious level, and most places such as homes and government offices treat water as drinking water and drink it as drinking water.

As such, a device for treating water and supplying it to drinking water is generally used as a water purifier for supplying cold water and hot water after purifying raw water supplied through a water pipe.

1 and 2 is a block diagram conceptually showing the configuration of a general water purifier according to the prior art.

The water purifier is generally equipped with a water supply valve V to open and close the supply of raw water on a water supply pipe Q through which raw water is supplied, and this water supply pipe Q is connected to the water filter 20. In the water filter 20, a plurality of filter devices may be selected so that a filtering process such as removing suspended substances, deodorizing, and sterilizing bacteria causing waterborne diseases may be performed, including suspended solids mixed in raw water. Mainly applied to sediment filter, pre-carbon filter, hollow fiber membrane filter / reverse osmosis filter, post-carbon filter Etc. are used.

The purified water passing through the water filter 20 is supplied to the storage tank 40 through the connection pipe (P), as shown in Figure 1, from the cold storage tank 40 and the hot water tank 50, respectively. Is supplied to, the cold water tank 30 and the hot water tank 50 is connected to the water intake coke 70 through the water intake pipe 73, respectively. The water intake coke 70 may be separately formed into a cold water intake coke 71 and a hot water intake coke 72.

Such a water purifier is always kept in a state in which the purified water is stored in the storage tank 40, and in this state, if the cold water or hot water is withdrawn by the intake coke 70, the purified water is stored in the cold water tank 30 and the hot water tank ( 50) to have a supplemental supply. At this time, the hot water tank 50 is formed with an air vent (not shown) in communication with the outside air for the internal pressure discharge.

On the other hand, in addition to such a structure, the structure of the water purifier which is generally used, as shown in FIG. 2, after the purified water passing through the water filter 20 is supplied to the cold water tank 30 through the connection pipe P, the cold water tank 30 ) Is supplied to the hot water tank 50, the cold water tank 30 and the hot water tank 50 may be configured in a manner that is connected to the water intake coke 70 through the water intake pipe 73, respectively. In such a water purifier, the cold water tank 30 serves as a storage tank and a cold water tank, and the purified water is always kept in the cold water tank 30, and in this state, when cold water or hot water is taken out by the intake coke 70, cold water The purified water is replenished to the hot water tank 50 from the tank 30, and water is replenished to the cold water tank 30 from the connection pipe P at the same time. At this time, the above-described air vent (not shown) is formed in the hot water tank 50.

Therefore, a general water purifier having such a structure is an air vent is formed in the hot water tank 50 for a stable operation, through which contaminants or bacteria of the air is introduced into the hot water tank 50 to the inside of the hot water tank 50. There was a problem of contamination. In particular, since bacteria are sterilized by high temperature in the hot water tank 50, it is not a big problem, but the storage tank 40 of FIG. 1 or the cold water tank 30 of FIG. 2 connected to the hot water tank 50 may have an internal temperature. Since the environment is suitable for bacterial propagation, the storage tank and the cold water tank are exposed to bacterial contamination by contact with air as it is. Thus, the purified water contaminated with bacteria in the storage tank and the cold water tank is cold water intake through the cold water intake coke 701. When water is taken with cold water, there was a problem of providing bacterial contaminated water to the user.

Since the problem of bacterial contamination must always exist in the general water purifier as described above, there is no other alternative for preventing bacterial contamination except the method of frequently cleaning the storage tank or the cold water tank, and frequently cleaning the storage tank or the cold water tank. If not, the water purifier installed to drink clean water, rather than drinking more contaminated water drinking water there was a problem that can cause a dysfunction.

On the other hand, since the conventional water purifier according to the prior art is configured so that the hot water tank 50 and the cold water tank 30 are in communication with each other, when the hot water tank 50 is full, from the hot water tank 50 to the cold water tank 30 There is a phenomenon that the hot water or water vapor flows backward, the cooling efficiency of the cold water tank 30 is significantly reduced by such a reverse flow phenomenon.

In addition, such a general water purifier is equipped with a heater (not shown) therein to heat the water stored in the hot water tank 50, such a heater is a water of the water so that the water stored in the hot water tank 50 can be maintained at a constant temperature It is configured to continue to operate repeatedly according to the temperature. Therefore, even when substantially no hot water is used, the energy consumption increases as the heater continues to be operated unnecessarily. In order to prevent such energy consumption, some users may switch off the heater so that the heater is turned off. It is true. However, if the heater is stopped in this way, the inside of the hot water tank is multiplying germs by contact with air, and if you want to use the hot water again, the heater is heated for a long time to heat all the water stored in the hot water tank. There was a problem of being very inefficient in that it had to work.

The present invention is invented to solve the problems of the prior art, the object of the present invention is to ensure that the heater operates only when using hot water through the instantaneous hot water bath, thereby preventing the repetitive operation of the heater in a certain temperature band energy It is to provide a water purifier that can reduce consumption.

Another object of the present invention is to provide purified water to the cold water tank and the instant hot water tank independently of each other to prevent bacterial contamination by air contact and at the same time to prevent the hot water backflow structurally to improve the cooling efficiency of the cold water energy due to the operation of the cooler It is to provide a water purifier to reduce the.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

The water purifier according to an embodiment of the present invention is configured such that the cold water tank and the hot water tank connected to the water filter are supplied with purified water through separate connection pipes, thereby preventing bacterial contamination by air contact of the cold water tank and cooling by hot water backflow. It is configured to prevent the decrease in efficiency, and also to operate the heater only when using hot water, thereby preventing unnecessary heater operation to reduce the energy consumption. The water purifier filters the flow of purified water to the purified water filter 200 for filtering raw water, the cold water tank 300 and the instantaneous hot water tank 400, and the instantaneous hot water tank 400, which are respectively connected to the purified water filter 200. Allowed or blocked hot water valve 500, the cold water tank 300 and the instantaneous hot water tank 500 and the water intake cock 700 connected through the water intake pipes 710 and 720, respectively, and a hot water selection operation unit operable by the user ( 600, and a control unit 800 for controlling these operations, each of these components may be configured in a form disposed in a separate body case 100.

Water purification filter 200 is a configuration for treating the raw water supplied through the water supply pipe (Q), as described in the prior art, such as sediment filter, pre-carbon filter, hollow fiber membrane filter / reverse osmosis filter, post carbon filter A plurality of filters are connected and installed, and raw water is filtered in multiple stages in the course of passing through the plurality of filters, which can be variously changed according to a user's needs.

Cold water tank 300 is connected to the purified water filter 200 and the first connection pipe (P1) is configured to supply and store the purified water passed through the purified water filter 200. At this time, the cold water tank 300 is provided with a separate cooler 320 to be described later is configured to cool the purified water introduced through the first connection pipe (P1) from the water filter 200.

Instantaneous hot water tank 400 is connected to the purified water filter 200 and the second connection pipe (P2) is configured to supply and store the purified water passed through the purified water filter 200. At this time, the first connection pipe (P1) and the second connection pipe (P2) are each composed of a separate pipe, the purified water passed through the water filter 200, respectively, the first connection pipe (P1) and the second connection, respectively The pipe P2 is independently supplied to the cold water tank 300 and the instant hot water tank 400, respectively. In addition, the instantaneous hot water tank 400 is provided with a separate heating means to quickly heat the purified water supplied to the instantaneous hot water tank 400, this heating means is excellent in heating efficiency according to an embodiment of the present invention It is preferable that a planar heater 480 is used, which is configured such that its operation is controlled by the controller 800.

The hot water valve 500 is mounted on the second connection pipe P2 to open and close to allow or block the flow of purified water flowing into the instant hot water tank 400, which is automatically changed according to an electrical signal by the controller 800. It is preferably configured in the form of a solenoid valve to open and close.

The intake coke 700 may be formed separately from the cold water intake coke 701 and the hot water intake coke 702 or may be formed in one piece, and the intake coke 700 may be cold water so as to intake cold water and hot water, respectively. The intake pipe 710 and the hot water intake pipe 720 are connected to the cold water tank 300 and the instantaneous hot water tank 400, respectively.

The hot water selection operation unit 600 is configured to be operated by the user so that the user can select the use of hot water when the user wants to take hot water, and the control unit 800 according to the operation of the hot water selection operation unit 600 by the user It is configured to control the opening and closing operation of the hot water valve 500 and the operation of the surface heater 480 of the instantaneous hot water tank 400.

According to this configuration, the water purifier according to the exemplary embodiment of the present invention opens the hot water valve 500 by the controller 800 only when the user selects the use of hot water through the hot water selection operation unit 600. The purified water is supplied to the furnace, and at the same time, the surface heater 480 is operated to quickly heat the purified water, and thereafter, hot water is withdrawn from the instant hot water tank 400 through the water intake coke 700. That is, the water purifier according to an embodiment of the present invention supplies water to the instantaneous hot water tank 400 only when hot water is to be used, and then quickly heats the water to be withdrawn, thereby preventing unnecessary heater operation unlike the prior art. It is a structure that can save energy.

In addition, the water purifier having such a structure, as shown in FIG. 3, the purified water passing through the water filter 200 independently through the first connection pipe P1 and the second connection pipe P2, respectively, is independently a cold water tank 300. And it is supplied to the instant hot water tank 400 is stored in each independent space. That is, the cold water tank 300 and the instantaneous hot water tank 400 is formed in an independent structure that does not communicate with each other, unlike the prior art, the intake coke 700 through the hot water intake pipe 720 and the cold water intake pipe 710, respectively ). Therefore, when the user takes cold water or hot water through the intake cock 700, the cold water is stored in the cold water intake pipe in the state where the cold water flows into the cold water tank 300 through the first connection pipe P1 from the water filter 200. 710 is withdrawn to the intake coke 700, the hot water is introduced into the instantaneous hot water tank 400 through the second connection pipe (P2) from the water filter 200, and then through the hot water intake pipe (720) Withdrawn to 700. The water purifier structure in which the cold water or the hot water is collected through this process is formed separately from the cold water tank and the hot water tank without communicating with each other, thereby preventing external air contact of the cold water tank 300 to prevent bacterial contamination of the cold water tank 300. Therefore, not only hot water but also cold water can be supplied in a clean state to prevent bacterial contamination.

Looking in more detail, the instantaneous hot water tank 400 according to an embodiment of the present invention performs the function of a hot water tank in a broad sense, as described in the prior art through the external communication means such as air vent in its structure The internal pressure is configured to be discharged, and the inside of the instantaneous hot water tank 400 comes into contact with the outside air through the external communication means. The germs can grow inside the instantaneous hot water tank 400 by such external air contact, but the breeding degree of bacteria is only a very small level because hot water is not always stored in the instantaneous hot water tank 400, and also hot water Since the hot water inside the hot water tank 400 at a time of intake becomes a high temperature state by heating, germs are all sterilized by heat, so that bacterial contamination is not a problem in hot water taken in through the hot water intake pipe 720. On the other hand, the bacterial contamination problem has been a problem of bacterial contamination of cold water, as described in the prior art, that is, the conventional general water purifier because the cold water tank and the hot water tank is formed in communication with each other or a separate storage tank is communicated with the cold water tank, Bacterial contamination generated in the storage tank or hot water tank is transferred to the cold water tank, so that the bacteria are taken into the intake coke together with the cold water in the state of large breeding in the cold water tank, bacterial contamination of the cold water has been a problem. However, since the cold water tank 300 according to an embodiment of the present invention is formed so as not to communicate with the instantaneous hot water tank 400 as described above, bacterial contamination by external air contact is not transmitted to the cold water tank 300. Not only the cold water tank 300 itself structure is also the structure that the external air contact is blocked. Therefore, since the purified water passing through the water filter 200 flows into the cold water tank 300 and is stored without contact with external air, contamination or bacterial contamination by external foreign matters is fundamentally prevented.

That is, the water purifier according to the embodiment of the present invention is formed in the instantaneous hot water tank 400 is not communicated with the cold water tank 300 and is independently connected to the water filter 200 through the independent connection pipe (P1, P2), respectively. Because it is connected, the external air contact generated in the instant hot water tank 400 is not transmitted to the cold water tank 300, and the external air contact of the cold water tank 300 is blocked, thereby preventing bacterial contamination, thereby not only hot water but also cold water Intake can also provide clean water that is not contaminated with bacteria.

In addition, the water purifier according to an embodiment of the present invention is because the instantaneous hot water tank 400 is formed independently without communicating with the cold water tank 300 and hot water is not always stored in the instantaneous hot water tank 400 at all times. Unlike the prior art, in the structure thereof, a phenomenon in which hot water flows back from the instant hot water tank 400 to the cold water tank 300 is prevented, thereby further improving cooling efficiency for cold water, thereby saving energy.

Looking at each configuration in more detail, first, the cold water tank 300, the cold water tank case 310 and the cold water tank case 310 is formed therein water storage space as shown in Figure 4 and 5 It is configured to include a cooler 320 is wrapped around the outer surface of the cold water tank case 310 so as to cool the purified water stored in. Cold water tank case 310 is equipped with a cold water tank inlet pipe 330 connected to the first connection pipe (P1) so that the purified water flows from the water filter 200, and also cold water through the water intake coke 700 The cold water tank discharge pipe 340 is connected to the cold water intake pipe 710 to be withdrawn. At this time, the cold water tank inlet pipe 330 is one end is connected to the first connection pipe (P1) from the outside of the cold water tank case 310 and the other end of the cold water tank case 310 is located on the inner upper layer of the cold water tank case (310). ), The cold water tank outlet pipe 340 is connected to the cold water intake pipe 710 at the outside of the cold water tank case 310 and the other end is located in the inner lower layer of the cold water tank case 310. It is preferable to penetrate through the case 310.

According to this structure, the cold water tank 300 obtains purified water through the cold water tank inlet pipe 330 from the lower layer of the cold water tank case 310 through the cold water tank outlet pipe 340. Cold water is discharged to the cold water intake pipe 710. This configuration has the advantage of being more energy efficient when supplying cold water to the user through the intake cock 700. That is, since the convection of the fluid generally occurs in a manner in which the cold fluid moves downward and the warm fluid rises in the predetermined space, relatively cold cold water is located in the lower layer inside the cold water tank case 310. Considering this convection phenomenon, it is more efficient with respect to the temperature of the cold water discharged, the other end of the cold water tank outlet pipe 340 located in the lower inner layer of the cold water tank case 310 as described above.

The cooler 320 is formed in a pipe shape surrounding the cold water tank case 310, and may be generally configured as an evaporator constituting a refrigeration cycle. Therefore, although not shown inside the main body case 100 of the water purifier, a compressor, a condenser, an expansion valve, and the like may be installed to circulate the refrigerant with the evaporator, which corresponds to a general configuration for cooling, and thus a detailed description thereof will be omitted. The cooler 320 is preferably formed to surround the central portion and the lower portion of the cold water tank case 310, as shown in Figures 4 and 5, through which the cold water stored in the cold water tank case 310 Cooling efficiency is coordinated with the convection of cold water and is further improved. On the other hand, it is preferable that a separate cold water temperature sensor 360 is mounted at a position adjacent to the other end of the cold water tank outlet pipe 340 in the lower layer of the cold water tank case 310, and thus the operating state of the cooler 320 is determined. Configured to control. That is, the temperature of the cold water discharged from the cold water tank inlet pipe 340 to the cold water intake pipe 710 is measured in such a way that the cooler 320 is operated or stopped according to the measured temperature. It is configured to be performed by one control unit 800.

On the other hand, the cold water tank case 310 is mounted so that the outer circumferential surface is separated from the inner surface of the cold water tank case 310 by a predetermined separation plate 350 is arranged horizontally on the lower layer of the cold water tank inlet pipe 330 Preferably, the purified water introduced into the upper layer of the cold water tank case 310 through the cold water tank inlet pipe 330 flows to the lower layer along the inner surface of the cold water tank case 310 and is cooled more effectively. That is, since the cooler 320 is configured to surround the cold water tank case 310, since the side portion is relatively lower in temperature than the center portion of the cold water tank case 310, the cooler 320 is introduced into the cold water tank case 310. By mounting the separator plate 350 so that the purified water flows down along the inner surface of the cold water tank case 310, more effective cooling performance may be exerted.

In addition, the cold water drain pipe 370 for discharging the purified water stored in the cold water tank case 310 is communicatively coupled to the cold water tank case 310 in the lower portion of the cold water tank case 310, such cold water drain pipe 370 It is preferable that a separate opening and closing valve 380 that can open and close the cold water drain pipe 370 is mounted. The cold water drain pipe 370 and the opening / closing valve 380 may be used when the cold water tank case 310 needs to be emptied completely according to the user's needs, such as when the cold water tank case 310 needs to be cleaned.

As shown in FIGS. 4 and 5, the instantaneous hot water tank 400 has a hot water tank case 410 having a purified water storage space therein, and one end thereof is connected to the second connection pipe P2 and the other end of the hot water tank case. Hot water tank inlet pipe 420 is coupled to the upper portion of the 410, and the hot water tank outlet pipe 430, one end is connected to the hot water intake pipe 720 and the other end is in communication with the lower portion of the hot water tank case 410. And, in order to discharge the internal pressure of the hot water tank case 410 and the hot water tank air vent 440 formed on the upper portion of the hot water tank case 410, it is mounted to be located on the bottom surface of the hot water tank case 410 described above As described above, the controller 800 includes a planar heater 480 that is controlled by the control unit 800.

In this case, the planar heater 480 used may be replaced by a general band heater or sheath heater, but per unit area so as to quickly heat the supplied water due to the characteristics of the instant hot water tank 400. It is preferable that the planar heater 480 be used in consideration of the amount of heat generated.

According to this structure, when the hot water valve 500 is opened, the instantaneous hot water tank 400 is supplied with purified water from the second connection pipe P2 to the hot water tank case 410 through the hot water tank inlet pipe 420, and then the surface heater. The hot water is collected and discharged from the hot water intake pipe 720 through the hot water tank discharge pipe 430 while being heated by the water 480. In this case, the hot water tank discharge pipe 430 is disposed at the lower portion of the hot water tank case 410. Since the surface is coupled in communication and the surface heater 480 is mounted on the bottom surface of the hot water tank case 410, the temperature of the hot water intake and discharged through the hot water tank outlet pipe 430 is further raised around the surface heater 480 Since intake and discharge can be performed, more rapid hot water heating is possible. That is, since the inlet of the hot water tank discharge pipe 430 is located adjacent to the surface heater 480, the temperature of the hot water intake and discharged through the hot water tank discharge pipe 430 is relatively high, so that the hot water tank case 410 Even though the stored hot water is not heated evenly as a whole, the temperature of the hot water discharged and discharged may correspond to an appropriate temperature. As a result, the actual hot water heating time for the hot water taken in is reduced, thereby enabling rapid hot water heating.

On the other hand, the instant hot water tank 400 is preferably equipped with a water level detector 450 that can detect the water level of the hot water stored in the hot water tank case 410, the water level detector 450 is configured in various forms For example, it may be configured in the form of detecting whether or not the water level of the hot water stored in the hot water tank case 410 is full water, or may be configured in the form of detecting the water level in stages. The level of the water level detector 450 is preferably configured in a form corresponding to the configuration of the hot water selection operation unit 600, the control unit 800 in accordance with the level of the hot water detected by the level sensor 450. It is preferable to be configured to control the operation of the hot water valve 500, which will be described later.

In addition, the instantaneous hot water tank 400 is preferably equipped with a hot water temperature sensor 460 that can detect the temperature of the hot water stored in the hot water tank case 410, the control unit 800 is such a hot water temperature sensor 460 It is preferable to be configured to control the operation of the surface heater 480 according to the temperature of the hot water sensed by the).

Looking at the flow of purified water for the water purifier of the configuration described above with reference to Figure 5, first, purified water is supplied to the water filter 200 through the water supply pipe (Q). The purified water supplied to the purified water filter 200 is filtered by the purified water filter 200 and then the cold water tank 300 and the instantaneous hot water tank 400 through the first connecting pipe P1 and the second connecting pipe P2, respectively. Independently supplied to), the purified water supply to the instantaneous hot water tank 400 is the hot water mounted on the second connection pipe (P2) only when the user selects the use of hot water through the hot water selection operation unit 600 as described above The valve 500 is opened to proceed with purified water supply. At this time, the first connection pipe (P1) and the second connection pipe (P2), as shown in Figure 5 may be configured in the form that the other connection pipe is branched to any one of the connection pipe, the water filter 200 It may also be configured in the form of completely different connecting pipes connected to each other.

In this way, the purified water stored in the independent cold water tank 300 that is not in communication with the instant hot water tank 400 is cooled through the cooler 320 and then the intake coke through the cold water intake pipe 710 when the intake coke 701 is operated. Intake is discharged to 701, wherein the cold water is discharged through the intake cock 700 from the cold water tank 300 is the flow pressure of the purified water supplied from the purified water filter 200 in the structure of the cold water tank (300) It is configured to be withdrawn by.

That is, the flow of cold water proceeds in such a way that the raw water continues to be supplied to the cold water tank 300 through the water supply pipe Q and the water filter 200 in a state in which the intake cock 700 is closed, so that the cold water tank 300 is full. Accordingly, the water pressure is generated in the cold water tank 300 by the flow pressure of the purified water supplied from the water filter 200, and when the water intake cock 700 is opened in this state, the water intake coke 700 is opened by the water pressure. Cold water is intake and discharged.

According to this cold water flow method, the water purifier according to an embodiment of the present invention is provided on the water supply pipe Q as shown in FIGS. 3 and 5 to adjust the water pressure due to the flow pressure of the water supply in the cold water tank 300. It would be desirable to be equipped with a separate pressure regulating valve 800 for boosting or reducing the pressure of the raw water. The pressure control valve 800 may be applied as a booster valve to increase the water pressure of the raw water when the water pressure of the raw water is relatively low in the place where the water purifier is installed, and if the water pressure of the raw water is relatively high to reduce the water pressure of the raw water. May be applied as a pressure reducing valve.

On the other hand, the flow of hot water through the instant hot water tank 400 is configured such that the flow of hot water occurs only when hot water use is selected by the user. That is, when the user selects and uses hot water through the hot water selection operation unit 600, the controller 800 opens the hot water valve 500 according to the operation signal of the hot water selection operation unit 600 as shown in FIG. 6. At the same time operating the surface heater 480, through which the purified water is supplied to the instant hot water tank 400 is heated. Thereafter, when the water intake coke 700 is opened, hot water is taken out and discharged from the instant hot water tank 400 to the water intake coke 700. At this time, unlike the cold water tank 300, the instantaneous hot water tank 400 is configured such that the hot water is taken in and discharged by the water pressure according to the position head of the hot water stored in the instantaneous hot water tank 400. That is, since the hot water tank discharge pipe 430 is coupled to the lower portion of the hot water tank case 410, water pressure is generated according to the height of the hot water stored in the hot water tank case 410, and in this state, the water intake cock 700 ) Is opened, hot water is taken out and discharged to the intake cock 700 by the water pressure.

In this case, the hot water selection operation unit 600 may be configured to have only a hot water selection button 610 that is operated in an on / off manner to simply select or deselect the use of hot water, but the user can adjust the amount of hot water intake The water intake amount may be configured to further include a hot water capacity selection button 620 to be operated in a selected manner, in addition to the temperature button for selecting the temperature of the hot water and the like may be variously changed.

When only the hot water selection button 610 is mounted and operated, the water level detector 450 mounted on the instantaneous hot water tank 400 may be configured to detect only a predetermined water level, for example, to detect whether water is full. Or it may be configured to detect the level of water level. On the other hand, when the hot water capacity selection button 620 is mounted and operated together, the water level detector 450 mounted on the instantaneous hot water tank 400 may have various heights so as to detect the water level selected by the hot water capacity selection button 620. It should be configured in the form of detecting water level.

When the hot water selection operation unit 600 is selected and operated by the user to use the hot water, as shown in FIG. 6, the controller 800 opens the hot water valve 500 and operates the surface heater 480. When the water level of the hot water detected by the water level detector 450 is full or reaches a level selected by the user, the controller 800 operates the hot water valve 500 in a locked state and supplies it to the instantaneous hot water tank 400. To shut off the flow of hot water. In this state, in the instant hot water tank 400, the hot water continues to be heated by the surface heater 480. At this time, when the temperature of the hot water detected by the hot water temperature sensor 460 reaches a preset temperature, the controller 800 Stops the operation of the surface heater 480. As such, when the heating state is completed, the user can take hot water through the water intake cock 700.

According to the hot water intake process, the water purifier according to an embodiment of the present invention further includes a separate heating completion display unit 900 so that a user can recognize a hot water heating completion state after operating the hot water selection operation unit 600. desirable. The heating completion display unit 900 is configured to be operation controlled by the controller 800, as shown in Figure 6, when the temperature of the hot water detected by the hot water temperature sensor 460 reaches the set temperature to the user. It is configured to display, and may be configured in various ways, such as flashing a separate lamp (not shown) or generating a warning sound. In addition, the hot water selection operation unit 600 and the heating completion display unit 900 is disposed adjacent to the water intake cock 700 on the front of the main body case 100, as shown in Figure 5 so that the user can be easily manipulated and recognized. Preferably, the hot water selection operation unit 600 and the heating completion display unit 900 may be integrally configured through one display device.

Therefore, the water purifier according to an embodiment of the present invention operates the hot water selection operation unit 600 first in order for the user to use hot water, and then manipulates the water intake cock 700 after the heating completion state is displayed through the heating completion display unit 900. It is configured to take hot water. According to such a configuration, when the intake coke 700 is opened while the heating process is not completed, the temperature of the hot water may be relatively low, so that the intake coke 700 is not operated when the heating process is not completed. An auxiliary restraining means (not shown) may be further provided, which may be implemented in an electrical circuit configuration or a mechanical configuration.

At this time, after the user uses hot water through the intake cock 700, the hot water is not used to store all of the hot water in the hot water tank 400, so that the hot water remains in the hot water tank case 410 of the hot water tank 400. In this case, the hot water remaining in the hot water tank case 410 is not a problem because the user is heated and discharged during the next hot water use, but when the user wants to empty the hot water tank case 410 completely as needed, A separate hot water drain pipe 470 may be communicatively coupled to the lower portion of the hot water tank case 410 so that hot water of the bath case 410 may be forcedly discharged. The hot water drain pipe 470 may be equipped with a separate on / off valve 471 to be configured to discharge hot water inside the hot water tank case 410 to the outside according to the opening / closing operation of the on / off valve 471.
