In one example, the resistance means 230 may include a material such as rubber having a friction force, or may include a material such as oil having a viscosity. In addition, the resistance means 230 may occur in various embodiments in a range that can reduce the lifting force applied to the moving case 220.

A detailed description of an example of the resistance means 230 will be described later.

In addition, in the present invention, the operation unit 410 is provided on the upper surface of the water extraction module 200, and the water extraction button 420 may be provided on the front surface of the water extraction module 200.

As described above, in order for the operation unit 410 to be provided on the upper surface of the water extraction module 200, an upper surface of the fixed case 210 may form a storage space in which the operation unit 410 is accommodated.

According to the present invention, the operation unit 410 is provided on the upper surface of the water extraction module 200, a tall adult user can easily adjust the overall operation of the water purifier 10. On the other hand, in the case of a child user with a short key, the operation unit 410 provided on the upper surface of the water extraction module 200 cannot be recognized and can not be easily operated even if it is recognized, by pressing the operation unit 410 at random, hot water is discharged. This can help prevent accidents such as burning your hands.

In addition, the water extraction module 200 may further include a front case 290 that covers the front surface of the fixed case 210.

When the front case 290 covers the front surface of the water extraction module 200 as described above, the configuration of the resistance member 230 and the guide portion 240, which will be described later, is not exposed to the outside, thereby fascinating the appearance of the water extraction module 200. I can keep it.

In addition, the front case 290 is detachably coupled to the fixed case 210, by separating the front case 290 from the fixed case 210, if necessary, to check the resistance member 230 and the guide portion 240 You may. For example, the front case 290 and the fixed case 210 may be coupled in a removable manner by a hook.

In addition, the front case 290 may include an upper edge 291 coupled to the upper end of the fixing case 210. The manipulation unit 410 may be accommodated in the edge 291. With the configuration of the edge 291, the coupling force of the front case 290 and the fixed case 210 may be higher.

In this embodiment, the front case 290 is formed with a water exit button exposure port, so that the water exit button 420 is exposed to the outside of the front case 290.

In addition, the water extraction nozzle 280 may be formed of a stainless steel (stainless steel) material.

When the water extraction nozzle 280 is formed of a stainless material as described above, it is hygienic because it is not rusted, and it is possible to prevent breakage and deformation occurring during frequent use. In addition, it is beautiful in appearance and can add a luxurious image to the water purifier 10.

In addition, the water extraction nozzle 280 may be formed integrally by the moving case 220, or the connection member 281 and the insert injection method for connecting the moving case 220 and the water extraction nozzle 280. have.

Here, the connection member 281 is a part connecting the water extraction nozzle 280 and the supply hose 190, it can be detachably coupled to the moving case (220).

6 is a front view showing the moving case of the water extraction module is raised, Figure 7 is a longitudinal cross-sectional view showing a moving case of the water extraction module is raised. And, Figure 8 is a front view showing the moving case of the water extraction module is lowered, Figure 9 is a longitudinal cross-sectional view showing the movement case of the water extraction module is lowered.

6 to 9, the fixing case 210 or the moving case 220 may be formed with a guide portion 240 for guiding the moving case 220 to rise and fall in a straight line.

Since the moving case 220 moves up and down in the state accommodated in the fixed case 210, the lifting operation of the moving case 220 may be linearly guided by the fixed case 210. However, when the moving case 220 is exposed to the outside of the fixed case 210, if the moving case 220 is slightly shaken to both sides, the lifting operation of the moving case 220 is unstable, such a phenomenon If repeated, it causes deformation and damage of the fixed case 210 or the moving case 220.

In the case of the present invention, to prevent this, it is provided with a separate guide portion 240.

The guide unit 240 may support various embodiments in a range in which the moving case 220 is supported by the fixed case 210 and can be guided up and down in a straight line.

For example, the guide part 240 may include a straight rail formed in the fixed case 210 in a vertical direction, and a roller formed in the moving case 220 to travel the straight rail.

On the contrary, the guide part 240 may include a straight rail formed on the moving case 220 in the vertical direction and a roller formed on the fixed case 210 to travel the straight rail.

As another example, the guide portion 240 is provided in the guide groove 241 formed along the lifting direction in the fixed case 210 and the moving case 220, the guide is fitted to the guide groove 241 Piece 242.

On the contrary, the guide part 240 may include a guide groove formed in the moving case 220 along a lifting direction, and a guide piece provided in the fixed case 220 and fitted into the guide groove.

At this time, the guide piece 242 is inserted into the guide groove 241 formed in the straight line, and moves in a straight line along the guide groove 241. Accordingly, the lifting operation of the moving case 220 may be made in a straight line.

In addition, the guide piece 242 may be rotatably mounted to the moving case 220.

When the guide piece 242 is rotatably mounted to the moving case 220 as described above, the guide piece 242 is along the guide groove 241 in a state of reducing the friction force with the guide groove 241 to a minimum. You can go up and down in a straight line. Therefore, the lifting operation of the moving case 220 may be performed more smoothly, and the operation feeling felt by the user may be improved.

In addition, the guide groove 241 has a first gear 241a is formed on the inner side, and the second gear 242a meshing with the first gear 241a is formed on the outer circumferential surface of the guide piece 242. Can be formed.

That is, the guide groove 241 and the guide piece 242 are engaged in the same manner as the rack and pinion, the guide piece 242 is rotated, ascending and descending in a straight line along the guide groove 241. Can be.

For example, when the user pulls down the moving case 220, the guide piece 242 rotates in the counterclockwise direction on the drawing, and descends along the guide groove 241 while the gear teeth 241a and 242a are engaged with each other. do.

On the contrary, when the user pushes the moving case 220 upward, the guide piece 242 rotates clockwise in the drawing and ascends along the guide groove 241 in a state where gear teeth 241a and 242a are engaged with each other.

When the gear teeth 241a and 242a are formed as described above, since the gear teeth 241a and 242a are engaged with each other, the guide piece 242 can rotate up and down more accurately along the guide groove 241 while rotating. As a result, the lifting and lowering of the moving case 220 may proceed in a straight line more accurately. In addition, the guide piece 242 prevents the guide groove 241 from being lost, so that the lifting of the moving case 220 can be performed precisely to the height desired by the user.

In addition, the first gear 241a or the second gear 242a may include a straight section or a curved section formed perpendicularly or inclined to the lifting direction of the moving case 220. In particular, the first gear 241a or the second gear 242a may be partially or entirely curved.

As described above, when the first gear 241a or the second gear 242a is formed in a curved shape, the first gear 241a and the second gear 242a may be smoothly engaged, and the user may feel The operation feeling can also be improved. In addition, in the process of the user holding the moving case 220, and lifting the moving case 220, the first gear by the force applied to the first gear (241a) or the second gear (242a) ( It is possible to prevent the 241a or the second gear 242a from being damaged.

If the first gear 241a or the second gear 242a is formed in a straight line, and sharp edges are formed, the force may be concentrated on the sharp portions, causing damage.

For example, the uneven portion of the first gear 241a or the second gear 242a may protrude or be concave in a semicircular shape.

In addition, the shapes of the first gear 241a and the second gear 242a are reliably transmitted while the second gear 242a rotates in engagement with the first gear 241a. Various embodiments may occur in a range in which the guide piece 242 may move in a straight line along the guide groove 241.

In addition, the resistance means 230 may be formed as an oil damper.

An oil damper means a device having oil in a housing and absorbing energy by the viscosity resistance of the oil.

As described above, the oil damper includes, for example, a cylindrical housing, an oil filled in the housing and having a predetermined viscosity, and a plurality of through holes received in the housing and through which the oil passes, and are parallel to the radial direction of the housing. It may include a rotary blade and a rotating shaft connected to the rotary blade.

Therefore, when the rotational force is supplied to the rotating shaft, it is possible to reduce the rotational force supplied by the viscous resistance of the oil.

10 is a perspective view showing a state in which a resistance member and a guide piece which are some components of the present invention are connected.

As shown, the resistance means 230 is formed of an oil damper, the guide piece 242 may be connected to the rotating shaft 231 of the resistance means 230.

That is, when a lifting force is applied to the moving case 220 to raise or lower the moving case 220, the guide piece 242 rotatably connected to the moving case 220 rotates.

At this time, the rotational force of the guide piece 242 is reduced by the resistance means 230, that is, the oil damper.

Therefore, in the state where the moving case 220 is completely accommodated in the fixed case 210, the moving case 220 may not be arbitrarily lowered by the viscous resistance of the resistance means 230, and thus the stored case 220 may be maintained. In addition, even if the user releases the hand from the moving case 220 in a state where the user grasps the moving case 220 and descends to a desired position, the moving case 220 is moved to a desired position by the viscous resistance of the resistance means 230. Can be fixed.

At this time, the oil viscosity of the oil damper may vary in the range that the resistance means 230 does not take excessive force for the user to operate the lifting case 220 while preventing the movement case 220 is lowered by its own weight. Can be adjusted. In addition, the oil viscosity of the oil damper can be adjusted in a variety of ranges to improve the operating sensitivity that the user feels.

11 is a cross-sectional view of a water extraction module which is a component of the present invention. 12 is an enlarged view illustrating an area A of FIG. 11.

11 to 12, the fixed case 210 and the moving case 220 may be in line contact.

Here, 'line contact' means that the fixed case 210 and the moving case 220 are in point contact, as in the cross sections of FIGS. 11 to 12, and the point contact is the lifting direction of the moving case 220. Continued along, it means that the fixed case 210 and the moving case 220 contacted in a linear form along the lifting direction of the moving case 220.

To this end, at least one or more contact protrusions 216 and 226 may be formed in the fixed case 210 or the moving case 220 along the lifting direction of the moving case 220.

For example, when the contact protrusion 216 is formed in the fixed case 210, the contact protrusion 216 is in line contact with the moving case 220. As another example, when the contact protrusion 226 is formed in the moving case 220, the contact protrusion 226 is in line contact with the fixed case 210.

In addition, the fixed case 210 and the moving case 220 are in contact with each other, the lifting operation of the moving case 220 can be made stable. In addition, deformation of the fixing case 210 and the moving case 220 due to mutual contact support may be prevented as much as possible.

For example, the contact protrusions 216 and 226 may have convex semicircular cross sections. When the contact protrusions 216 and 226 are formed in a curved surface as described above, the lifting operation of the moving case 220 may be performed more smoothly while the fixed case 210 and the moving case 220 are in line contact.

In addition, the fixed case 210 forms a wing portion 215 extending outwardly on both sides of the rear, the moving case 220, the wing portion 215 on both rear sides of the moving case 220. ) And an extension part 255a extending in parallel with each other, and a bent part 255b extending in a shape bent forward from the extension part 255a and having a hook 225c inward at an end thereof. The wing 215 may be accommodated in the receiving groove 227 between the extension 255a and the hook 225c.

In addition, at least one of the fixed case 210 or the moving case 220 may be formed of an engineering plastic material having excellent fatigue resistance, toughness, abrasion resistance, and the like and having lubricity.

For example, at least one of the fixed case 210 or the moving case 220 may be formed of polyoxymethylene (POM) material.

Therefore, when the mobile case 220 is moved up and down inside the fixed case 210, wear and noise due to friction between the fixed case 210 and the mobile case 220 may be reduced.

In addition, when the user pulls down the moving case 220 or raises the lowered moving case 220, the lifting operation of the moving case 220 proceeds smoothly, thereby increasing the operation sensitivity.
