Description
Technical Field
The present invention relates to a drinking water supply device such as a water purifier or a water dispenser, and more particularly to a water intake structure of a drinking water supply device.
Background
A water purifier or a water dispenser is typically used as a drinking water supply apparatus. In general, the water intake portion with the water intake tap of such a drinking water supply apparatus is always exposed to the outside. Such an exposed water intake portion is easily contaminated and has a sanitary problem.
Here, patent document 1 discloses a water treatment apparatus (water purifier) including a moving part provided with a water outlet (water intake faucet) and capable of moving back and forth in the front-rear direction at the upper part of an apparatus main body. In addition, a sterilization space for accommodating the water outlet is formed in the moving part. According to the water treatment apparatus disclosed in patent document 1, a user slides (moves forward) the moving unit that carries the water outlet forward of the apparatus main body to expose the water outlet when taking water, thereby taking water, and restores (moves backward) the moving unit to the upper part of the apparatus main body when waiting (when not taking water), thereby preventing the water outlet from being exposed for a long time. In addition, the sterilizing water may be periodically or aperiodically supplied to the sterilizing space during the standby time, so that the inside and the outside of the water outlet port accommodated in the sterilizing space may be sterilized.
However, in the water treatment apparatus of patent document 1, the moving part is formed on the entire upper part of the apparatus main body, and the moving part is configured to slide as necessary, so that the moving part becomes larger than necessary, and the slide driving mechanism becomes larger accordingly. Further, when the moving part is moved forward, the upper surface of the rear side of the device main body is exposed to the outside, and thus contaminants may enter the water outlet or the sterilization space disposed inside the moving part.
Also, the space between the device body and the moving part should be completely sealed when the moving part is in place to prevent the sterilizing water supplied to the sterilizing space from leaking to the outside of the device. However, it is difficult to achieve both perfect sealing and smooth sliding of the moving part. That is, if complete sealing is achieved, the moving part is made difficult to slide, and if the moving part is intended to be moved smoothly with a small force (low capacity, low power motor), complete sealing must be sacrificed. In addition, the frequent sliding of the moving part causes abrasion of the sealing member, resulting in a reduction in life span and leakage of the sterilizing water.
Further, when a user who is not skilled in operating the water treatment apparatus of patent document 1 places an article on the upper portion of the apparatus (the upper portion of the moving portion), the article may drop when the moving portion retreats forward and backward, and the heavy article may hinder the sliding of the moving portion or promote the abrasion of the seal.

In accordance with a preferred embodiment of the present invention to solve the above problems, there is provided a drinking water supply device having a water intake unit with a water intake faucet on a front surface thereof, the drinking water supply device including: a water intake cover, the upper end of which is mounted on the front cover of the drinking water supply device and can rotate around a rotating shaft arranged in the drinking water supply device, and the lower end of which is mounted with a water intake tap; a drive mechanism for driving the water intake cover so that the water intake cover can rotate about the rotation axis. The water intake cover is configured to be rotatable about the rotation axis between a first position where a lower end of the water intake cover protrudes toward a front side of the drinking water supply device to expose the water intake faucet to a front side of the drinking water supply device and a second position where the lower end of the water intake cover is retracted toward a rear side of the drinking water supply device to hide the water intake faucet inside the front cover of the drinking water supply device.
According to an embodiment, the drinking water dispenser further comprises a receiving tub for receiving the water tap when the lower end of the water taking part cover is retracted rearward of the drinking water supply device so that the water tap is located at a position capable of being hidden inside the front cover of the drinking water supply device.
At this time, preferably, the containing tub has a tub shape with an upper opening and has a side wall higher than a lower end of the water taking tap when the water taking tap is located at a position capable of being hidden; among the side walls, at least a front side wall located on the front cover side is formed of soft rubber or resin, and a lower end of the water intake faucet that rotates in accordance with the rotation of the water intake section cover can pass through the front side wall while elastically deforming the front side wall.
In the drinking water supply device according to the present invention, when the lower end of the water intake cover is retracted rearward of the drinking water supply device so that the water intake tap is positioned to be hidden inside the front cover of the drinking water supply device, the water intake tap can be cleaned by supplying wash water through a flow path connected to the water intake tap.
In this case, the drinking water supply device includes a sterilizing water generating unit, and the sterilizing water generated by the sterilizing water generating unit can be supplied as the washing water.
In the drinking water supply device, the rotation shaft also serves as a pipe for supplying drinking water to the water faucet.
In this case, the rotary shaft is formed of a T-shaped pipe, a lower end of the T-shaped pipe is connected to the water intake faucet, and both sides of an upper end of the T-shaped pipe are connected to flow paths for supplying drinking water having different properties.
In the drinking water supply device according to the present invention, the drive mechanism includes a motor and a coupling rod, and one end of the coupling rod is connected to a rotation shaft of the motor and the other end thereof is connected to the water intake cover.
Alternatively, the drive mechanism may include a motor and a gear that transmits power between a rotation shaft of the motor and the water intake cover or the rotation shaft.
Further, the driving mechanism is provided with a pneumatic cylinder or an oil hydraulic cylinder for pushing and pulling the water taking part cover.
The drinking water supply device of the invention is provided with a water taking button, when a user presses the water taking button for taking water, the lower end of the water taking part cover protrudes to the front side of the drinking water supply device, so that the water taking faucet is exposed to the front of the drinking water supply device; when a predetermined time has elapsed after the water intake is completed, the lower end of the water intake lid is retracted to the rear of the drinking water supply device so that the water intake tap is hidden inside the front lid of the drinking water supply device.
The water purifier of the present invention has the following effects.
First, the water tap is prevented from being exposed to the outside at all times, thereby preventing the water tap from being contaminated and improving the sanitation of the drinking water supply apparatus.
In addition, since the water intake unit of the water intake faucet is driven to rotate, the water intake faucet can be exposed and hidden by a simple and small driving mechanism.
In addition, no special sealing is needed between the rotatable water taking part and the front cover of the drinking water supply device, so that the problem of abrasion of a sealing piece caused by the hidden appearance of the water taking part is solved.

Detailed Description
The present invention will be described in detail below with reference to specific examples. However, the terms or words used in the present specification and claims should not be construed as being construed in a general or most basic meaning, and the inventor should interpret their meanings and concepts according to the technical idea of the present invention, appropriately define the concept of the term in order to explain his own invention in the best way. Therefore, the configurations described in the embodiments and shown in the drawings in the present specification are merely preferred embodiments of the present invention, and do not represent the technical ideas of the present invention, and it should be understood that various equivalents and modifications may be substituted in the present application.
For convenience of explanation and clarity, the sizes of components and specific portions constituting the components in the drawings are enlarged, omitted, or briefly shown. Therefore, the size of each component does not completely reflect the actual size. A detailed description of known techniques or configurations will be omitted when it is considered that the detailed description of known techniques or configurations may unnecessarily obscure the subject matter of the present invention.
In the following description, a water purifier is described as a drinking water supply device, but the present invention is also applicable to other drinking water supply devices such as a water dispenser.
In addition, the water purifier according to the following embodiment is a so-called direct drinking water purifier, which is a water purifier that receives raw water from a raw water supply source such as a water supply channel, and generates purified water by filtering through a filter, and supplies the purified water directly to a user without being stored in a storage tank. That is, the purified water is generated and directly supplied to the user when the user presses the water intake button. However, the present invention is applicable not only to a direct-drinking water purifier but also to a non-direct-drinking water purifier having a storage tank.
Fig. 1 is a perspective view showing an appearance of a water purifier in a standby state (non-water intake state) according to an embodiment of the present invention, and fig. 2 is a block diagram schematically showing an internal configuration and a flow path thereof.
First, referring to fig. 1, the water purifier 100 of the present embodiment includes a front cover 11, side covers and a top cover 12, and a rear cover (not shown) for incorporating the respective members. However, the overall appearance of the water purifier including the front cover shown in fig. 1 is merely an example, and the division and shape of the cover may be variously changed according to the embodiment.
The front cover is provided at an upper portion thereof with a water intake unit 50 (see fig. 3 and the like) having a water intake tap 51 (see fig. 2, fig. 4 and the like), and in the state shown in fig. 1 (standby state), the water intake tap 51 is not exposed, and only a water intake unit cover 52 constituting the water intake unit 50 is exposed on the front surface of the water purifier. A water intake button 15 is exposed below the water intake unit 50 in the front cover 11, and the generation of purified water and water intake are started and continued while the user presses the water intake button 15 with a container such as a cup. Further, a water receiving tank 13 is disposed on the lower front side of the front cover 11.
On the other hand, although not shown in fig. 1, the front cover 11 is provided with an operation panel on which members such as selection buttons for selecting water having different properties such as purified water, cold water, and warm water, and a display lamp for displaying the state of the water purifier are arranged or displayed. In the present embodiment, the operation panel is disposed on the surface of the water intake portion cover 52. For this reason, a circuit board 60 (see fig. 3 and the like) corresponding to the operation panel is mounted on the back surface, i.e., inside, of the front cover 11.
Referring to fig. 2, the water purifier 100 according to the present embodiment may include a filter member 20, a cold water generating unit 30, a hot water generating unit 32, and a sterilized water generating unit 34.
The filtering part 20 receives raw water from the raw water supply source S to filter and generate purified water, and typically may include a pre-treatment filter 21, a main treatment filter 22, and a post-treatment filter 23. The pretreatment filter 21 may be a sediment filter and/or a pre-activated carbon filter, or a filter in which a sediment filter and a pre-activated carbon filter are integrated. The main treatment filter 22 may be a hollow fiber ultrafilter, a reverse osmosis filter, or the like, and the reverse osmosis filter has a low filtration rate and a small capacity and is not suitable for a small-sized direct-drinking water purifier. The post-treatment filter 23 may use a post-activated carbon filter or a sterilizing filter.
On the other hand, the number, type and arrangement of the filters constituting the filter member 20 may be variously changed or combined according to the embodiment, and the configuration of the filters is widely known without direct relation to the features of the present invention, and a detailed description thereof will be omitted.
The cold water generating unit 30 is a unit for cooling and supplying the purified water generated by the filter member 20, and may use a double-tube cooler, an ice storage cooler, a cooler using an electric heating element, or the like.
The hot water generation unit 32 is a unit for heating and supplying the purified water generated by the filter member 20, and a heater having a small box shape incorporating a heat generating device suitable for instantaneous heating may be used.
On the other hand, according to the embodiment, the cold water generating unit 30 and the hot water generating unit 32 may not be provided, and various known types of coolers or heaters may be used, which are not directly related to the features of the present invention, and thus, detailed description thereof will be omitted.
The sterilizing water generating unit 34 is a unit for generating sterilizing water for sterilizing and disinfecting the water intake faucet 51 described later, and is a member different from the sterilizing filter described above. That is, the sterilizing filter is typically a device that sterilizes purified water by an ultraviolet lamp and the sterilized purified water is drunk as drinking water, but the sterilizing water generated by the sterilizing water generating unit 34 is used for sterilizing and disinfecting a flow passage pipe, a water tap, and the like of the water purifier, and the sterilizing water itself is discharged and is not drunk.
For this reason, as the sterilized water producing unit 34, typically, an electrolytic cell is used which produces a hypochlorous acid aqueous solution as the sterilized water by electrolyzing the water. The electrolytic cell for generating sterilizing water is not directly related to the features of the present invention, and the detailed configuration of the electrolytic cell for a water purifier is widely known, and thus, a detailed description thereof is omitted. However, since pure water passing through all the filters of the filter member 20 contains a small amount of solid components and ionic components and the electrolysis is not smooth, it is preferable to supply water passing through only a part of the filters 11 to the sterilized water producing unit 34 using an electrolytic cell.
As shown in fig. 2, the sterilizing water generated by the partial filter 11 and the sterilizing water generating module 34 is finally supplied to the water tap 51 through the flow path 41, and the purified water generated by the filter member 20 and the cold water or hot water generated by the cold water generating module 30 or the hot water generating module 32 are also finally supplied to the water tap 51 through the respective flow paths 42, 43, and 44. Therefore, the water purifier 100 is provided with a necessary flow path pipe depending on the flow direction of water, a valve 47 for opening and closing the flow path pipe as necessary, and a check valve (not shown) or a pump (not shown) for preventing the water from flowing backward as necessary. However, the flow path arrangement and the valve 47 shown in fig. 2 are merely an example, and various changes may be made according to the embodiment.
Next, the water intake section 50, which is a characteristic structure of the present invention, will be described in detail with reference to fig. 3 to 8A, 8B, and 8C.
First, although only the surface of the water intake portion cover 52 is exposed to the outside of the front cover in fig. 1, the water intake portion cover extends rearward, that is, inside the front cover 11 (see fig. 52a) as seen in fig. 3, 4, 6, and 7, and has a substantially triangular cross-sectional shape as seen from the side (see fig. 7). In addition, an opening through which the water intake part cover 52 penetrates is formed in the front cover 11 so as to correspond to the extending portion 52a of the water intake part cover 52 extending rearward.
The upper end 52b of the water intake cover 52 is rotatably attached around a rotation shaft 54 provided at the inner upper portion of the front cover 11. Accordingly, the water intake cover 52 is rotated about the rotation shaft 54, the upper end 52b of the water intake cover 52 is fixed to the upper portion of the water purifier 100, and the lower end 52c can be protruded toward the front of the water purifier 100 or retracted rearward.
On the other hand, a water intake tap 51 is fixed to a lower end 52c of the water intake cover 52. Therefore, the water intake tap 51 is exposed to the outside of the water purifier 100 (see fig. 6 or 7) or is located at a position hidden inside the water purifier 100 as the position of the lower end of the water intake cover 52 changes.
The water intake unit 50 includes a drive mechanism that drives the water intake unit cover 52 to be rotatable about a rotation shaft 54, and finally, the water intake tap 51 is concealed (i.e., exposed and concealed). In the present embodiment, the drive mechanism has a motor 55 and a connecting rod (link) 56. The motor 55 is preferably a stepping motor or a servo motor that can achieve precise rotation control. One end of the connecting rod 56 is connected to the rotating shaft 55a of the motor 55, and the other end is connected to one end of the water intake cover 52. In particular, in the present embodiment, the connecting rod 56 has the same structure as the crankshaft, and one end of the water intake portion cover 52 functions as a connecting rod (connecting rod) to convert the rotational movement of the motor 55 into the reciprocating movement of the water intake portion cover 52. However, in the crank mechanism, one end of the water intake portion cover 52 functioning as a connecting rod (connecting rod) is formed in the shape of an elongated hole 53, unlike a normal crank pin, and the elongated hole 53 allows the connecting rod 56, which is a crank shaft, to freely move within a certain range, thereby smoothly realizing motion conversion in a narrow space.
The operation of the drive mechanism of the present embodiment will be described in further detail with reference to fig. 8A, 8B, and 8C.
Fig. 8A shows a state in which the water intake portion cover 52 is closed, that is, the state of fig. 1 and 4, in which the other end of the connecting rod 56, that is, the connecting rod portion located at the long hole 53 formed at one end of the water intake portion cover 52 is located on the right side of the rotating shaft 55a of the motor 55 and at the lower end inside the long hole 53.
At this time, when the rotation shaft 55a of the motor 55 is rotated counterclockwise in the figure to open the water intake portion cover 52, as shown in fig. 8B, the other end of the link lever 56 moves toward the upper end of the elongated hole 53 inside the elongated hole 53, and pushes the water intake portion cover 52 leftward.
At this time, when the rotation shaft 55a of the motor 55 is further rotated counterclockwise, as shown in fig. 8C, the other end of the link 56 further pushes the water intake portion cover 52 leftward, moves toward the lower end of the elongated hole 53 inside the elongated hole 53, and reaches the lower end of the elongated hole 53, the water intake portion cover 52 is opened.
To close the water intake cover 52 that is opened, the rotating shaft 55a of the motor 55 is rotated clockwise in the opposite direction to the above.
On the one hand, such a drive mechanism is not limited to the crank mechanism shown in the present embodiment. That is, as shown in fig. 9A, the drive mechanism may be embodied as a gear mechanism having a motor 55, a gear 61a provided on a rotating shaft 55a of the motor, and a gear 61b provided on one end of the water intake section cover 52. As shown in fig. 9B, the driving mechanism may be embodied such that the rotating shaft 54 is rotated by a motor (not shown) directly or via a gear. Further, as shown in fig. 9C, the driving mechanism may be embodied as a pneumatic or hydraulic cylinder 62 for pushing and pulling the water segment cover 52.
With the configuration and the driving mechanism of the water intake unit 50, the lower end of the water intake unit cover 52 can be projected forward of the water purifier 100 to expose the water intake faucet 51 when taking water, and the lower end of the water intake unit cover 52 can be retracted rearward of the water purifier 100 to hide the water intake faucet 51 when waiting. In particular, when the user presses the water intake button 15 (see fig. 1) to take water, the water intake portion cover 52 is rotated to a position where the water intake faucet 51 can be exposed, and if a predetermined time elapses after water intake is completed, the water intake portion cover 52 is automatically rotated to a position where the water intake faucet 51 can be concealed again, thereby minimizing exposure of the water intake faucet 51.
As described above, the present invention can realize the concealment of the water intake tap 51 by a relatively simple structure and a simple action (less power and energy). In addition, no special sealing member is required between the water intake part cover 52 and the opening of the front cover 11. Therefore, there is no problem of seal wear due to the hidden (exposing and hiding) action of the water tap 51.
On the other hand, the water tap 51 is cleaned by supplying wash water through a flow path connected to the water tap 51 during standby (when the water tap is in a hidden position). Here, drinking water may be used as it is, or the sterilized water generated by the sterilized water generating unit 34 may be used. However, when the water is washed and sterilized by the sterilizing water generated by the sterilizing water generating unit 34, it is necessary to supply the drinking water to the water tap 51 for flushing after the sterilizing water is used.
In any case, it is necessary to drain the washing water (sterilizing water, rinsing water), and for this purpose, a drain tub 57 capable of draining the washing water is provided below the water intake tap 51 located at the hidden position, or at least a drain flow path 57b communicating with the water intake tap 51 located at the hidden position is provided.
Further, as shown in fig. 3 to 5, the water purifier 100 may further have a receiving tub 58, the receiving tub 58 receiving the water taking tap 51 when the water taking tap 51 is located at the hidden position. The containing tub 58 is used not only for washing the inside of the water tap 51 but also for washing the outer surface portion around the front end portion of the water tap 51. That is, in the case where the water tap 51 is accommodated in the accommodating tub 58, the accommodating tub 58 is filled with the wash water discharged through the water tap 51, and at this time, the front end of the water tap 51 is also immersed in the wash water, and as a result, the outer surface portion around the front end portion of the water tap 51 immersed in the wash water can also be washed.
For this purpose, the receiving tub 58 has a tub shape with an upper opening, and a side wall thereof is higher than the lowermost end of the water tap 51 when the water tap 51 is in the hidden position. In this case, when the water intake tap 51 rotates with the rotation of the water intake portion cover 52, the lower end of the water intake tap 51 is caught by the front side wall 58a of the side wall of the storage tub 58 on the front cover 11 side, and the water intake tap 51 and the water intake portion cover 52 cannot rotate any more.
Therefore, in the present embodiment, at least the front wall 58a of the side walls of the storage tub 58 is formed of soft rubber or resin, so that the lower end of the water intake tap 51 that rotates in response to the rotation of the water intake lid 52 can pass through the front wall 58a while elastically deforming the front wall 58 a. That is, the lower end of the water intake tap 51 can ride over the front sidewall 58 a.
Further, by cutting one or both sides of the front wall 58a to a height at least allowing the lower end of the water faucet 51 to pass (see arrow a in fig. 5), the thickness of the front wall can be made thinner than the other side walls, and elastic deformation of the front wall can be facilitated.
On the other hand, a drain port 58b through which washing water, particularly, sterilizing water and rinsing water, can be discharged is formed at a lower portion of the storage tub 58, so that the washing water after washing the water faucet 51 can be discharged to the drain tub 57.
However, at this time, if the diameter of the drain port 58b is excessively large, the receiving tub 58 may not be filled with the washing water. Therefore, the size of the drain port 58b should be set such that the supply amount of the washing water supplied to the water tap 51 is larger than the amount of the washing water discharged through the drain port 58 b. Alternatively, even if the diameter of the drain hole is set large, the lower end of the water intake tap 51 can be immersed in the wash water in the following manner.
That is, a valve is provided to open and close the drain passage 57b of the drain tub 57, a water level sensor 59 is provided in the drain tub 57 to measure the water level in the drain tub 57 (that is, the water level of the storage tub 58 communicating with the drain tub through the drain port 58 b), and the opening and closing of the drain passage 57b is controlled based on the measured water level. At this time, the storage tub 58 is omitted and the drain tub 57 functions as a storage tub.
On the other hand, the rotary shaft 54 can also serve as a pipe for supplying drinking water to the water intake faucet 51. Specifically, as shown in fig. 3, the turning shaft 54 is formed as a T-shaped pipe, the upper end of the water intake portion cover 52 is rotatably attached to the turning shaft 54, the lower end of the T-shaped pipe is connected to the water intake tap 51, and both sides of the upper end of the T-shaped pipe are connected to the flow paths 44 and 45 for supplying drinking water or sterilizing water having different properties such as warm water, purified water, and cold water, respectively. This can reduce the number of components.
The present invention has been described above with reference to the specific embodiments and the accompanying drawings, but the present invention is not limited thereto, and it is needless to say that those skilled in the art to which the present invention pertains can modify and change the present invention within the scope equivalent to the technical idea of the present invention and the claims.
