Description

Technical Field

[0001] The present invention relates to a water purifier equipped with a filter sensing sensor. More specifically, through the filter sensing sensor, the coupling state of the water purification filter can be accurately and stably sensed. When the water purification filter is not coupled, the water outlet function is automatically blocked to prevent non-purified water from being discharged or water from overflowing inside the water purifier, so that it can be used more stably. The present invention relates to a water purifier equipped with a filter sensing sensor.

Background Art

[0002] Recently, due to the rapid industrial development, the environmental pollution has become serious. Among them, water pollution has reached a serious level, and in most places such as homes and government offices, water is purified and used as drinking water.

[0003] In homes, water purifiers are used to purify water. Generally, a water purifier is connected to a water supply pipe such as a water supply pipe for the upper water supply, automatically receives the raw water from the upper water supply, filters the raw water through a filter device inside the water purifier, and discharges it through a water outlet.

[0004] Different from the water purifiers used in homes, in spaces where water supply pipes are not installed, such as offices, raw water cannot be supplied through the water supply pipes, so water purifiers that can be used in such restricted spaces have been developed.

[0005] Such a water purifier is structured such that the user directly supplies raw water to the water tank inside the water purifier, filters the raw water stored in the water tank through a water purification filter, and discharges it through a water outlet.

[0006] When the raw water stored in the water tank of such a water purifier is used up, the user newly supplies the raw water to the water tank using a water bucket or the like, and the water purification filter is also configured to be directly replaced by the user at regular intervals.

[0007] The water filter replacement process involves removing the old, worn-out filter and then inserting a new one. However, if the water dispensing button is accidentally pressed before inserting the new filter, water will be supplied from the tank to the outlet. In this process, without a filter, water may leak through the connection point, potentially wetting the surrounding environment or causing the water purifier to malfunction. Furthermore, if water is dispensed through the outlet without a filter, unfiltered water will be released, posing a health risk to the user.

[0008] Therefore, in situations where the water filter has been removed, such as during water filter replacement, a safety device is needed to prevent water from being dispensed through the outlet even if the user operates the water dispensing button. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Registered Patent No. 10-1721676 of the Republic of Korea [Overview of the project] [Problems that the invention aims to solve]

[0010] This invention was made to solve the problems of the prior art, and the object of this invention is to provide a water purifier equipped with a filter sensing sensor that senses the coupling state of the water purification filter and automatically shuts off the water dispensing function if the filter is not coupled, thereby preventing unpurified water from being dispensed or water from overflowing into the water purifier and causing malfunction, and enabling more stable use.

[0011] Another object of the present invention is to provide a water purifier equipped with a filter sensing sensor that can accurately sense the state of filter connection and improve safety during use and enable efficient management through various controls, including water discharge function, depending on the state of filter connection.

[0012] Another object of the present invention is to provide a water purifier equipped with a filter sensing sensor that not only senses the filter coupling state but also automatically performs a flushing mode when the filter is coupled to improve the water purification state in the initial stages of filter coupling, and displays the filter replacement time and status to the user to further improve user convenience. [Means for solving the problem]

[0013] The present invention provides a water purifier equipped with a filter sensing sensor, comprising: a main case; a water tank disposed inside the main case for storing raw water; a water filter disposed inside the main case and connected to the water tank via a first connecting line for filtering the raw water supplied from the water tank; a water outlet connected to the water filter via a second connecting line for discharging the purified water filtered through the water filter to the outside; a base plate formed to securely support the water tank, with a filter coupling portion formed on one side for the water filter to be detachably coupled; a filter sensing sensor module for sensing whether the water filter is coupled to the filter coupling portion; and a control unit that controls the operation to stop the water discharge function through the water outlet when the filter sensing sensor module detects that the water filter is not coupled.

[0014] At this time, the filter coupling portion is formed in a form that is recessed into one side of the base plate so that the water purification filter can be inserted and secured, and the filter sensing sensor module is coupled through the filter coupling portion so that its upper end protrudes from the bottom surface of the filter coupling portion, and is arranged so that the water purification filter can be pressurized by the water purification filter when it is inserted into the filter coupling portion.

[0015] Furthermore, a through-hole is formed on one side of the bottom surface of the filter coupling portion so that the filter sensing sensor module is coupled through it. The filter sensing sensor module may include a movable body that is inserted through the through-hole and elastically supported so as to move up and down and protrude upward from the bottom surface of the filter coupling portion, and a sensing sensor disposed below the movable body that generates a sensing signal when pressurized and released by the up and down movement of the movable body.

[0016] Furthermore, a hollow cylindrical guide sleeve is formed on the lower surface of the filter coupling portion, protruding downward along the outside of the through-hole, and the movable body is coupled through the guide sleeve so that its vertical movement path is guided by the guide sleeve, allowing it to move up and down.

[0017] Furthermore, a sealing body can be attached to the movable body to prevent water from flowing out downwards through the through-hole and guide sleeve from the filter coupling portion.

[0018] Furthermore, the sealing body includes a support body that closely contacts and surrounds the outer circumferential surface of the moving body, and a sealing pad that protrudes in a direction radiating along the outer circumferential surface of the support body, with its outer end closely contacting the inner circumferential surface of the guide sleeve. The sealing pad is flat and can be formed to be elastically deformable by frictional force with the inner circumferential surface of the guide sleeve as it moves together with the moving body.

[0019] Furthermore, the control unit can control the operation of the supply pump connected to the first connecting line and the water outlet valve connected to the water outlet so that water can be discharged through the water outlet, and can control the operation of the supply pump and water outlet valve to stop operating when the filter sensing sensor module detects that the water purification filter is not connected.

[0020] Furthermore, if the filter sensing sensor module detects that the water purification filter has been newly connected, the control unit can be controlled to perform a flushing mode in which purified water is discharged through the outlet at a preset standard flow rate from the moment of detection.

[0021] Furthermore, the flashing mode can be initiated by user operation or set to start automatically.

[0022] Furthermore, the main case is formed with a display unit capable of displaying information on when the water purification filter needs to be replaced. When the filter sensing sensor module detects that the water purification filter has been newly connected, the control unit can be controlled to display the replacement time for the water purification filter on the display unit after a preset usage time has elapsed from the time of detection.

[0023] Furthermore, the main case is equipped with a warning light, and the control unit can control its operation so that the warning light illuminates when the filter sensing sensor module detects that the water purification filter is not connected. [Effects of the Invention]

[0024] According to the present invention, by detecting the connection state of the water purification filter and automatically shutting off the water outlet function when the filter is not connected, it is possible to prevent the situation where unpurified water is discharged, or water overflows inside the water purifier and causes a malfunction, and thus it has the effect of enabling more stable use.

[0025] In addition, it is possible to accurately detect whether the filter is connected through the filter detection sensor, and there is an effect that the safety of use can be improved and efficient management can be achieved through various controls including the water outlet function according to whether the filter is connected.

[0026] In addition, not only can the filter connection state be detected, but also when the filter is connected, the flushing mode is automatically executed to improve the water purification state at the initial stage of filter connection, and the replacement time and state of the filter are displayed to the user, which has the effect of further improving the user convenience.

[0035] Figure 1 is a schematic perspective view showing the external shape of a water purifier equipped with a filter sensing sensor according to one embodiment of the present invention, and Figure 2 is a conceptual diagram shown to explain the flow of water to the water purifier equipped with a filter sensing sensor according to one embodiment of the present invention.

[0036] A water purifier according to one embodiment of the present invention is a device that can sense whether the internal water purification filter 300 is connected or not, and can control the operation of the water dispensing function by sensing the signal, and comprises a main case 100, a water tank 200, a water purification filter 300, a water outlet 400, a base plate 500, a filter sensing sensor module 600, and a control unit 700.

[0037] First, as described in the background art, one embodiment of the present invention may be designed in which the user directly supplies raw water to the water tank inside the water purifier without connecting it to the water supply piping, but it is not limited to this. In other words, a structure in which raw water is automatically supplied by connecting it to the water tank inside the water purifier may also be applied.

[0038] For the sake of clarity, the following explanation will be based on a configuration where the user directly supplies raw water to the 200-liter water tank without connecting it to the municipal water supply piping.

[0039] The main case 100 forms the external shape and support structure of the water purifier device, and has an internal storage space. An operation button 110, a warning light 120, and a display unit 130 can be formed on one side. A cup support is formed on the front surface of the main case 100, and a water outlet 400 can be positioned on top of the cup support.

[0040] The water tank 200 is located inside the main case 100 to store raw water. The water filter 300 is located inside the main case 100 and is connected to the water tank 200 via a first connecting line (L1) to filter the raw water supplied from the water tank 200. A supply pump 210 can be attached to the first connecting line (L1) to ensure a smooth supply of raw water from the water tank 200 to the water filter 300.

[0041] A connector 320 is connected to the water purification filter 300, and the connector 320 has an inlet 321 and an outlet 322. One end of the first connecting line (L1) is connected to the water tank 200, and the other end of the first connecting line (L1) is connected to the inlet 321 of the connector 320. Raw water supplied from the water tank 200 through the first connecting line (L1) flows into the internal space of the water purification filter 300 through the inlet 321 of the connector 320, undergoes a filtering process inside, and is discharged to the outside through the outlet 322 of the connector 320.

[0042] The water purification filter 300 is connected to the water outlet 400 via a second connecting line (L2). One end of the second connecting line (L2) is connected to the outlet 322 of the connector 320 of the water purification filter 300, and the other end of the second connecting line (L2) is connected to the water outlet 400.

[0043] The purified water filtered through the water filter 300 is discharged through the outlet 322 of the connector 320 and supplied to the outlet 400 through the second connecting line (L2). The outlet 400 can be opened and closed through a solenoid-operated outlet valve 410, and when the outlet valve 410 is open, purified water is discharged through the outlet 400.

[0044] The control unit 700 controls the operation of the water outlet valve 410 based on the operation signal from the operation button 110. For example, if a user operates the operation button 110 to dispense water, the operation signal from the operation button 110 is applied to the control unit 700, and the control unit 700 opens the water outlet valve 410 in response to the applied operation signal. At the same time, the supply pump 210 can be activated so that water from the water tank 200 is supplied to the water outlet 400 via the water purification filter 300.

[0045] A water purifier according to one embodiment of the present invention can filter the raw water in the water tank 200 through the structure described above and discharge the purified water through the outlet 400.

[0046] The following section provides a more detailed explanation of the filter sensing sensor module 600, which can detect whether the water purification filter 300 is connected, and its related configuration.

[0047] Figure 3 is a schematic perspective view showing the water filter coupling structure of a water purifier equipped with a filter sensing sensor according to one embodiment of the present invention, Figure 4 is a schematic bottom perspective view showing the mounting structure of the water filter and filter sensing sensor module of a water purifier equipped with a filter sensing sensor according to one embodiment of the present invention, and Figures 5 and 6 are schematic drawings showing the operating state of the filter sensing sensor module of a water purifier equipped with a filter sensing sensor according to one embodiment of the present invention.

[0048] As shown in Figure 3, a separate base plate 500 is installed inside the main case 100.

[0049] The base plate 500 is formed in a generally flat shape so that the water tank 200 is securely supported on its upper surface, and a filter coupling portion 510 is formed on one side so that the water purification filter 300 can be detachably coupled to it.

[0050] The filter sensing module 600 can be coupled to the base plate 500 to sense whether the water purification filter 300 is coupled to the filter coupling part 510. The filter sensing module 600 can be implemented through various types of sensors, which will be described in detail later.

[0051] If the filter sensing module 600 detects that the water purification filter 300 is not connected, the control unit 700 receives the sensing signal from the filter sensing module 600 and controls its operation to stop the water discharge function through the water outlet 400 based on the applied sensing signal.

[0052] For example, if the filter sensing module 600 detects that the water purification filter 300 is not connected, the control unit 700 can keep the water outlet valve 410 of the water outlet 400 closed, even if the user generates a water outlet operation signal using the operation button 110, and can also keep the supply pump 210 stopped. In other words, the water outlet function can be controlled to stop through the closing operation of the water outlet valve 410 and the stopping of the supply pump 210.

[0053] As a result, even if the user accidentally operates the operation button 110 when the water purification filter 300 is not connected, the water dispensing function will stop and no water will flow. This prevents water from overflowing into the water purifier and causing it to malfunction, or the surrounding environment from getting wet, ensuring safe use. In addition, it prevents unfiltered raw water from being discharged through the water outlet 400, thus ensuring more stable hygiene and safety.

[0054] To explain the structure of the filter sensing module 600 in more detail, first, the filter coupling portion 510 of the base plate 500 is formed in a form that is recessed on one side of the base plate 500 so that the water purification filter 300 can be inserted and secured.

[0055] At this time, the filter sensing module 600 is connected through the filter coupling portion 510 such that its upper end protrudes from the bottom surface of the filter coupling portion 510, and is positioned so that it can be pressurized by the water purification filter 300 when the water purification filter 300 is inserted into the filter coupling portion 510.

[0056] More specifically, a through-hole 511 is formed on one side of the bottom surface of the filter coupling portion 510 so that a filter sensing sensor module 600 is coupled through it. The filter sensing sensor module 600 includes a movable body 610 that is inserted through the through-hole 511 and elastically supported so as to move up and down and protrude upward from the bottom surface of the filter coupling portion 510, and a sensing sensor 620 that is positioned below the movable body 610 and generates a sensing signal when pressurized and released by the up and down movement of the movable body 610.

[0057] At this time, a hollow cylindrical guide sleeve 512 is formed on the lower surface of the filter coupling portion 510, protruding downward along the outside of the through hole 511, and the movable body 610 is connected through the guide sleeve 512 so that its vertical movement path is guided by the guide sleeve 512, and moves up and down.

[0058] An elastic member that applies an upward elastic force to the movable body 610 can be separately installed in the internal space of the guide sleeve 512. However, in one embodiment of the present invention, a switch-type sensing sensor 620 can be applied, and the elastic force generated by the switch structure of the sensing sensor 620 can be used to provide upward elastic support to the movable body 610.

[0059] As shown in Figure 5, when the water purification filter 300 is removed from the filter coupling portion 510, the movable body 610 is positioned so that it protrudes upward from the bottom surface of the filter coupling portion 510 by elastic force. In this state, the sensing sensor 620 is not pressurized, so the sensing sensor 620 generates an OFF signal indicating that the water purification filter is not present.

[0060] As shown in Figure 6, when the water purification filter 300 is inserted and coupled to the filter coupling part 510, the water purification filter 300 pressurizes the movable body 610 downwards, causing the movable body 610 to move downwards and pressurize the sensing sensor 620 downwards. In this state, the sensing sensor 620 generates an ON signal indicating that the water purification filter has been installed.

[0061] On the other hand, water remaining in the water purification filter 300 may flow out and accumulate in the filter coupling section 510 during the process of removing the water purification filter 300. The water accumulated in the filter coupling section 510 may flow out to the bottom through the through hole 511 and the gap space of the movable body 610, and the water that flows out to the bottom can flow into the sensing sensor 620. If the water accumulated in the filter coupling section 510 flows into the sensing sensor 620 in this way, it may cause the sensing sensor 620 to malfunction or fail.

[0062] In one embodiment of the present invention, a separate sealing body 630 is connected to the filter coupling portion 510 to prevent water from flowing into the sensing sensor 620.

[0063] The sealing body 630 is coupled to the moving body 610 and configured to block the movement of water within the internal space of the guide sleeve 512. For example, the sealing body 630 includes a support body 631 that is in close contact with the outer circumferential surface of the moving body 610 and surrounds the outer circumferential surface of the moving body 610, and a sealing pad 632 that protrudes in a direction radiating along the outer circumferential surface of the support body 631 and whose outer end is formed to be in close contact with the inner circumferential surface of the guide sleeve 512.

[0064] The support body 631 and the sealing pad 632 can be formed integrally from an elastic material, and the sealing pad 632 can be configured to be flat in shape and elastically deform due to frictional force with the inner surface of the guide sleeve 512 as it moves together with the moving body 610.

[0065] In this manner, the sealing pad 632 maintains a tight seal with the inner surface of the guide sleeve 512 through elastic deformation, thus completely preventing water from passing through the through hole 511 and flowing out into the guide sleeve 512 space.

[0066] Such a sealing body 630 is formed to move up and down together with the movable body 610 and to be fixed in position during the process of moving up and down together with the movable body 610.

[0067] For this purpose, the movable body 610 can be configured to include a cylindrical movable body portion 611 that extends vertically, a pressurizing plate portion 612 that extends horizontally to pressurize the sensing sensor 620 at the lower end of the movable body portion 611, and an extended stepped jaw portion 613 that extends at the upper end of the movable body portion 611 to form an extended stepped jaw. The sealing body 630 is tightly bonded to the outer circumferential surface of the movable body portion 611 so as to be located between the pressurizing plate portion 612 and the extended stepped jaw portion 613, and its vertical position is fixed at that position by the pressurizing plate portion 612 and the extended stepped jaw portion 613. In other words, the sealing body 630 moves up and down together with the movable body 610 while its relative position to the movable body 610 is fixed.

[0068] On the other hand, the sensing sensor 620 is placed inside a sensor housing 622, which is formed in the shape of an open container at the top and bottom, and is elastically supported by a separate elastic spring so as to protrude upward from the top of the sensor housing 622. The mobile body 610 can be supported by the elastic force of the sensing sensor 620 so as to protrude from the top of the filter coupling portion 510. As shown in Figure 4, the sensor housing 622 is fixed to the bottom of the filter coupling portion 510 via a separate support load 621, and the vertical height of the sensor housing 622 can be adjusted by adjusting the coupling length of the support load 621. The height of the sensing sensor 620 is adjusted by adjusting the vertical height of the sensor housing 622, and through this, the height at which the mobile body 610 protrudes from the bottom surface of the filter coupling portion 510 can be adjusted.

[0069] This structure allows the filter sensing module 600 to accurately sense whether the water purification filter 300 is connected to the filter coupling part 510, and to maintain a stable operating state without damage or malfunction due to water leakage.

[0070] Figure 7 is a schematic functional block diagram showing the control-related configuration of a water purifier equipped with a filter sensing sensor according to one embodiment of the present invention.

[0071] As described above, in one embodiment of the present invention, if the water purification filter 300 is not connected, the operation control is such that the water dispensing function is stopped even if the operation button 110 is operated.

[0072] To this end, the control unit 700 controls the operating state of the supply pump 210 and the water outlet valve 410 by receiving the operation signal from the operation button 110 and the sensing signal from the filter sensing sensor module 600.

[0073] A warning light 120 and a display unit 130 can be formed in the main case 100 as shown in Figure 1, and the display unit 130 can display information on when the water purification filter 300 needs to be replaced. The replacement time information can be expressed in various ways, such as showing the degree to which the replacement time has been reached in scale or graph form, or in text form.

[0074] When the filter sensing sensor module 600 detects that a new water purification filter 300 has been connected, the control unit 700 can control the operation so that, after a preset usage time has elapsed from the time of detection, the replacement time for the water purification filter 300 is displayed on the display unit 130.

[0075] For example, if the filter sensing sensor module 600 detects that the water purification filter 300 has been removed and a new water purification filter 300 has been installed, the control unit 700 can control the system so that, if the replacement period for the water purification filter 300 is, for example, 6 months, after 4 months have elapsed, the replacement period for the water purification filter 300 (2 months remaining) is displayed on the display unit 130.

[0076] Furthermore, if the filter detection sensor module 600 detects that the water purification filter 300 is not connected, the control unit 700 can control the operation so that the warning light 120 on the main case 100 illuminates.

[0077] This allows the user to recognize that the water purification filter 300 is not connected, prompting them to quickly replace the filter 300. Furthermore, even if the user operates the water dispensing button or other controls in this state, the system can still be used to inform them that the water dispensing function is disabled.

[0078] On the other hand, if the filter sensing sensor module 600 detects that a new water purification filter 300 has been connected, the control unit 700 can control the operation so that a flushing mode is performed from the moment of detection, in which purified water is discharged through the outlet 400 at a preset standard flow rate.

[0079] When the filter sensing sensor module 600 detects that the water purification filter 300 has been removed and a new water purification filter 300 has been installed, the control unit 700 can operate the supply pump 210 to open the water outlet valve 410 and control the system so that purified water is discharged through the water outlet 400 at a standard flow rate (for example, 1L to 3L).

[0080] This flushing mode allows the newly replaced water filter 300 to be washed before formal use. In other words, any foreign matter that may be present in the new water filter 300 can be discharged to the outside along with the water.

[0081] This flushing mode can be initiated automatically when the water purification filter 300 is replaced, that is, when a detection signal is generated by the filter sensing sensor module 600, or it can be started when the user approves the progression of the flushing mode.

[0082] The above description is merely illustrative of the technical concept of the present invention, and a person with ordinary skill in the art to which the present invention belongs will be able to make various modifications and variations without deviating from the essential characteristics of the present invention. Therefore, the embodiments disclosed herein are for illustrative purposes only, not to limit the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments.
