Description

[0001] The present invention relates to a water supply device having a water intake part,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drinking water supply device such as a water purifier or a water heater, and more particularly to a water intake structure of a drinking water supply device.

A typical drinking water supply device is a water purifier or a water heater. In such a drinking water supply device, it is general that the water intake including the water intake cock is always exposed so that the water can be taken by the user. The exposed water intake part is vulnerable to contamination, which causes hygiene problems.

Patent Document 1 discloses a water treatment apparatus (water purifier) having a moving portion capable of moving forward and backward in the fore and aft direction on the upper portion of the apparatus main body, and having a water discharge port (water intake cock) in the moving portion. In this moving part, a sterilizing space is formed in which a water outlet is accommodated. According to the water treatment apparatus according to Patent Document 1, when the user intends to take water, the moving unit including the water outlet is slid forward (forward) to the front of the apparatus body to expose the water discharge port, ), The moving part is retracted (retracted) to the upper part of the apparatus main body to prevent the water outlet from being exposed at all times. Also, at the time of waiting, sterilized water is supplied to the sterilizing space periodically or non-periodically to sterilize the inside and the outside of the water outlet accommodated in the sterilizing space.

However, the water treatment apparatus of Patent Document 1 has a structure in which a moving portion is formed over the entire upper portion of the apparatus body and, if necessary, the moving portion is moved by sliding, the moving portion is enlarged more than necessary and the sliding driving mechanism is also enlarged. Also, while the moving part is moving forward, the rear upper surface of the device body is exposed, through which contaminants can penetrate into the water outlet or sterilizing space disposed inside the moving part.

When the moving part is in the home position, a complete sealing between the main body and the moving part is required so that the sterile water supplied to the sterilizing space does not leak out of the apparatus. However, it is difficult to achieve perfect sealing and smooth sliding of the moving part. In other words, perfect sealing will make sliding of the moving part difficult, and sacrifice perfect sealing to smoothly move the moving part with a small force (low capacity, low power motor). In addition, due to frequent movement of the moving part, the seal is worn out, shortening the life span and causing leakage of sterilized water.

Further, when a user who is unfamiliar with the water treatment apparatus of Patent Document 1 places an object on the upper part of the apparatus (the upper part of the moving part), when the moving part comes off in front or rear, or when heavy objects interfere with sliding of the moving part, . ≪ / RTI >

The terms and words used in the specification and claims should not be construed to be limited to ordinary or dictionary meanings, and the inventor should properly define the concept of the term to describe its invention in the best way possible. It should be construed as meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

In the drawings, the size of each element or a specific part constituting the element is exaggerated, omitted or schematically shown for convenience and clarity of description. Therefore, the size of each component does not entirely reflect the actual size. In the following description, it is to be understood that the detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In the following description, a water purifier is described as an example of a drinking water supplying device, but it goes without saying that the present invention is also applicable to other drinking water supplying devices such as a water heater.

In addition, the water purifier according to the following embodiments is a so-called water purifier, which receives raw water from a raw water supply source such as a water supply, filters it through a filter to generate purified water, and supplies it to the user without storing it in a separate storage tank It is a water purifier. That is, when the user presses the water intake button, the user generates an integer and immediately supplies it. However, the present invention is not limited to a direct water purifier, but may be applied to a non-woven water purifier having a storage tank.

FIG. 1 is a perspective view showing an appearance of a water purifier according to an embodiment of the present invention when the water purifier is in a waiting state (non-condensing state), and FIG. 2 is a block diagram schematically showing an internal configuration and a flow path.

First, referring to FIG. 1, a water purifier 100 according to the present embodiment includes a front cover 11, side and top covers 12, and a rear cover (not shown). However, the appearance of the entire water purifier including the cover shown in Fig. 1 is merely an example, and the division and the form of the cover can be variously changed according to the embodiment.

A water intake portion 50 (see Fig. 3, etc.) including a water intake cock 51 (see Figs. 2 and 4, etc.) is provided at an upper portion of the front cover 11. In the state Only the water intake cover 52 constituting the water intake portion 50 is exposed on the front face of the water purifier without the waterproof cover 51 exposed. The water intake button 15 is exposed under the water intake portion 50 in the front cover 11. Generally, while the user presses the water intake button 15 with a container such as a cup, do. Further, a water receiver 13 is disposed in front of and below the front cover 11.

Although not shown in FIG. 1, the front cover 11 is provided with a selection button for selecting water having different properties such as water, cold water, and hot water, and a lamp for indicating the condition of the water purifier, Panel is installed. In this embodiment, the operation panel is disposed on the surface of the intake cover 52. To this end, a circuit board 60 (see Fig. 3, etc.) corresponding to the operation panel is mounted on the back surface of the front cover 11, that is, inside thereof.

2, the water purifier 100 of the present embodiment may include a filter unit 20, a cold water generating module 30, a hot water generating module 32, and a sterilizing water generating module 34.

The filter unit 20 is a filter for receiving raw water from a raw water supply source S to generate purified water. The filter unit 20 may typically include a pretreatment filter 11, a present treatment filter 12 and a post-treatment filter 13. As the pretreatment filter 11, a precipitate filter and / or a line carbon filter or a filter in which a precipitate filter and a line carbon filter are integrally integrated can be used. The UF hollow fiber membrane filter or the reverse osmosis filter may be used as the treatment filter 12, but in the case of the reverse osmosis filter, the filtration speed and the capacity are small, so that it may not be suitable for the small direct water type purifier. As the post-treatment filter 13, a post-carbon filter or a sterilizing filter can be used.

The number, type, and arrangement of the filters constituting the filter unit 20 can be variously modified and combined according to the embodiments, and the detailed configuration of the filters is not directly related to the characteristics of the present invention, , And a detailed description thereof will be omitted.

The cold water generating module 30 is a module for cooling and supplying the purified water generated by the filter unit 20, and can be a double tube type cooler, an ice cooling heat type cooler, a cooler using a heating element, or the like.

The hot water generating module 32 is a module for heating and supplying the purified water generated by the filter unit 20, and a heater in the form of a small tank containing a heater suitable for instantaneous heating can be used.

Meanwhile, the cold water generating module 30 and the hot water generating module 32 may not be provided according to the embodiments, and various known types of coolers or heaters may be used and are not directly related to the features of the present invention. The description is omitted.

The sterilizing water generating module 34 is a module for generating a sterilizing water for sterilizing and disinfecting the water intake cock 51 to be described later, and is a component different from the sterilizing filter described above. That is, the sterilizing filter is typically used to sterilize the purified water by using an ultraviolet lamp and sterilize the purified water as drinking water while the sterilizing water generated by the sterilizing water generating module 34 is used as the sterilizing filter, It is used for sterilization and disinfection, and the sterilized water itself is drained without drinking.

To this end, an electrolyzer typically used to electrolyze water to produce an aqueous hypochlorous acid solution as sterilized water may be used as the sterilization water generating module 34. The electrolyzer for generating the sterilizing water is not directly related to the characteristics of the present invention, and the detailed configuration of the electrolyzer used in the water purifier is well known, and a detailed description thereof will be omitted. However, since the electrolytic solution does not flow smoothly due to a small amount of solid component or ion component in the purified water passing through all the filters of the filter unit 20, only a part of the filter 11 passes through the sterilization water generating module 34 employing the electrolyzer It is preferable to supply one water.

2, the sterilizing water produced by passing through the filter 11 and the sterilizing water generating module 34 is supplied to the water intake coke 51 through the flow path 41, 20 and the cold water or hot water generated by passing through the cold water generating module 30 or the hot water generating module 32 are ultimately supplied to the intake cock 51 ). Accordingly, the water purifier 100 has the valves 47 for arranging the required flow pipe according to the flow of water and opening and closing the flow pipe according to need, and if necessary, A valve (not shown), and a pump (not shown). However, it is needless to say that the flow path arrangement and valve 47 shown in Fig. 2 are merely examples and various modifications can be made in accordance with the embodiments.

Next, the water intake portion 50 having the characteristic construction of the present invention will be described in detail with reference to Figs. 3 to 8. Fig.

1, only the front surface of the intake cover 52 is exposed to the outside of the front cover 11. However, referring to FIGS. 3, 4, 6 and 7, the rear cover, that is, the front cover 11 (See FIG. 7) and a substantially triangular cross-sectional shape when viewed from the side (see FIG. 7). An opening portion through which the intake cover 52 penetrates is formed in the front cover 11 corresponding to the extended portion 52a extending to the rear of the intake cover 52. [

The upper end 52b of the intake portion cover 52 is rotatably mounted around the pivot shaft 54 provided in the upper portion inside the front cover 11. [ The upper end 52b is fixed to the upper portion of the water purifier 100 and the lower end 52c is fixed to the front of the water purifier 100, So that it can be retracted rearward.

On the other hand, a water intake cock 51 is mounted and fixed to the lower end 52c of the water intake cover 52. Therefore, the water intake cock 51 can be exposed to the outside of the water purifier 100 (refer to FIGS. 6 and 7) according to the lower end position of the water intake cover 52, or can be placed in a concealed position inside the water purifier 100 .

The intake portion 50 includes a drive mechanism for rotating the intake portion cover 52 about the rotation shaft 54 and consequently projecting and withdrawing the water intake cock 51. In this embodiment, the driving mechanism is composed of a motor 55 and a link 56. The motor 55 is preferably a step motor or a servomotor capable of precise rotation control. One end of the link 56 is connected to the rotation shaft 55a of the motor 55 and the other end is connected to one end of the intake portion cover 52. Particularly, in this embodiment, the link 56 has the same structure as the crankshaft, and one end of the intake portion cover 52 serves as the connecting rod, so that the rotational motion of the motor 55 is transmitted to the intake portion cover 52, As shown in FIG. However, one end of the intake cover 52 serving as a connecting rod in the crank mechanism takes the form of a long hole 53 in which the link 56, which is a crank shaft, can flow in a certain range, unlike a typical crank pin, It is possible to convert smooth motion in a narrow space.

The operation of the driving mechanism of this embodiment will be described in more detail with reference to Fig.

8A shows a state in which the intake cover 52 is closed, that is, the state shown in Figs. 1 and 4, the other end of the link 56, that is, The link portion located in the long hole 53 formed at one end of the elongated hole 52 is located on the right side in the drawing and also located in the lower end inside the elongated hole 53. [

8 (b), when the rotary shaft 55a of the motor 55 is rotated in the counterclockwise direction in the figure to open the intake cover 52 in this state, the other end of the link 56 The water intake cover 52 is pushed to the left while simultaneously moving toward the upper end of the slot 53 in the long hole 53. [

When the rotation shaft 55a of the motor 55 is further rotated in the counterclockwise direction in this state, as shown in Fig. 8 (c), the other end of the link 56 moves to the left And moves to the lower end of the slot 53 from the inside of the slot 53. When reaching the lower end of the slot 53, the outlet cover 52 is opened.

In order to close the open intake cover 52, the rotating shaft 55a of the motor 55 may be rotated clockwise, as opposed to the above.

On the other hand, such a drive mechanism is not limited to the crank mechanism as in this embodiment. 9 (a), the drive mechanism includes a motor 55, a gear 61a provided on the rotation shaft 55a of the motor, and a gear (not shown) provided on one end of the intake portion cover 52 61b, respectively. 9 (b), the drive mechanism may be implemented by a method of rotating the rotary shaft 54 directly or via a gear by a motor (not shown). Further, the driving mechanism may be realized by a pneumatic or hydraulic cylinder 62 which pushes or pulls the intake cover 52, as shown in Fig. 9 (c).

The lower end of the water intake cover 52 is projected forward of the water purifier 100 to expose the water intake cock 51 when the water intake part 50 is structured and driven by such a structure of the water intake part 50 and the drive mechanism, The lower end of the take-out cock 52 can be retracted to the rear of the water purifier 100 to conceal the take-out cock 51. Particularly, when the user presses the water intake button 15 (see Fig. 1) for water intake, the water intake cover 52 is rotated to the position where the water intake cock 51 is exposed, and when the water intake is completed and the predetermined time has elapsed, It is possible to minimize the exposure of the water intake cock 51 by rotating the water intake cover 52 to the position where the water intake cock 51 is concealed again.

As described above, according to the present invention, it is possible to make the water intake cock 51 appear and disappear with a relatively simple structure and a simple operation (low force and energy). Further, according to the present invention, no special sealing is required between the intake cover 52 and the opening of the front cover 11. Therefore, there is no problem that the sealing is worn with respect to the protruding and retreating operation of the water intake cock 51.

On the other hand, when waiting (when the water intake cock is in the concealed position), the water intake cock 51 can be cleaned by supplying the cleansing water through the channel connected to the water intake cock 51. As the washing water, the drinking water may be used as it is, or sterilized water produced by the sterilization water generating module 34 may be used. However, when the water intake cock 51 is cleaned and sterilized by the sterilizing water generated by the sterilizing water generating module 34, it is necessary to supply the drinking water to the water intake cock 51 and rinse the sterilized water.

In either case, it is necessary to drain the washing water (sterilized water, rinse water). To this end, a drainage tank 57 capable of draining washing water is provided below the water intake cock 51 at the concealed position, It is necessary that the drain passage 57b is provided in alignment with the concealed position of the intake cock 51.

3 to 5, the water purifier 100 may further include a receiving cylinder 58 for receiving the water intake cock 51 when the water intake cock 51 is in the concealed position . The receiving cylinder 58 is provided not only to the inside of the intake coke 51 but also to the outside portion around the leading end of the intake coke 51. That is, when the washing water discharged through the water taking-in coke 51 in the state in which the water taking-in coke 51 is stored in the receiving cylinder 58 fills the receiving cylinder 58, the leading end of the water taking coke 51 is immersed in the washing water , And as a result, it is possible to clean the outer portion around the front end of the water intake cock 51 that is submerged in the washing water.

For this purpose, the receiving cylinder 58 has a cylindrical shape with its upper opening, and its side wall has to be formed higher than the lowermost end of the intake cock 51 when the intake cock 51 is in the concealed position. In this case, when the water intake cock 51 rotates in accordance with the rotation of the water intake cover 52, the front side wall 58a located on the side of the front cover 11 among the side walls of the receiving cylinder 58 The bottom end is caught, and rotation of the water intake cock 51 and the water intake cover 52 may be impossible.

Therefore, in this embodiment, at least the front side wall 58a of the side wall of the receiving cylinder 58 is made of soft rubber or resin and the lower end of the water intake cock 51, which rotates in accordance with the rotation of the intake side cover 52, So that the front side wall 58a is allowed to pass while being elastically deformed. That is, the lower end of the water intake cock 51 is configured to push and move the front side wall 58a.

5). Further, the thickness of the front side wall 58a is made thinner than that of the other side walls 58a (see Fig. 5) by cutting at least one side or both sides of the front side wall 58a through the lower end of the intake coke 51 The elastic deformation of the front side wall 58a can be made easier.

On the other hand, a drain port 58b for draining washing water, in particular sterilized water and rinse water, is formed on the lower side of the receiving cylinder 58 to discharge the washing water having been taken out of the water intake cock 51 to the drain cylinder 57 can do.

However, in this case, if the diameter of the drain port 58b is too large, the receiving cylinder 58 may not be filled with the washing water. Therefore, it is necessary to set the size of the drain port 58b such that the supply flow rate of the washing water supplied to the water intake cock 51 is equal to or larger than the flow rate at which the washing water is drained through the drain port 58b. Alternatively, even if the diameter of the drain port 58b is increased, the lower end of the water intake cock 51 may be immersed in the washing water in the following manner.

A water level sensor 59 is provided in the drain tank 57 to provide a water level of the drain tank 57 (eventually, the drainage port 58b And the opening and closing of the drain passage 57b may be controlled in accordance with the measured level. In this case, the receiving cylinder 58 may be omitted and the drain cylinder 57 may serve as the receiving cylinder.

On the other hand, the pivot shaft 54 can also serve as a pipe for supplying drinking water to the water intake cock 51. 3, the rotating shaft 54 to which the upper end of the water intake cover 52 is rotatably mounted is formed of a T-shaped pipe, and the lower end of the T-shaped pipe is connected to the water intake cock 51, And both sides of the upper end of the T-shaped pipe may be connected to drinking water having different properties such as hot water, purified water or cold water, or the flow paths 44 and 45 for supplying sterilizing water, respectively. As a result, the number of components can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. And various modifications and variations are possible within the scope of the appended claims.
