A tool 211 is formed.

In detail, the cover unit 200 may be configured to include a closure part 210, a rotating cover part 220, and a shield support part 230.

It is formed in a semicircle shape so that the angle is 180 degrees. However, this is one embodiment, and of course, the length can be set in accordance with the set rotation angle of the rotating cover part 220.

Meanwhile, although not shown, a stopper protrusion is seated in the guide groove 215 so that the user can intuitively detect the above-described use mode and storage mode positions as the user rotates the rotating cover unit 630 in each mode. It can include possible configurations.

In one embodiment of this configuration, the guide groove 215 can be configured to have a wider width for each mode point than other parts so that the stopper protrusion is seated at each mode point.

Alternatively, as a different embodiment, various embodiments are possible, such as forming the guide groove 215 deeper than other parts so that the stopper protrusion can be seated at each mode point.

As described above, the guide groove 215 and the stopper protrusion prevent excessive rotation of the rotating cover 220, preventing damage to the shield support 233 as well as unintentional damage to the cover unit 200. It prevents disassembly and guides the rotating cover 220 so that it can rotate stably within the operating section.

Meanwhile, at least one of the side surface of the stopper protrusion and the inner surface of the guide groove 215 facing each other in the use mode will be formed with an inclined surface to reduce the external force of the stopper protrusion deviating from the guide groove 215. You can.

The above-described inclined surface allows the stopper protrusion to move beyond the guide groove 215 when a certain external force is applied.

That is, when the rotating cover 220 moves in the use mode, the shield support 230 moves downward, and when the rotating cover 220 moves further in the corresponding direction, as will be described later. If the movement of the support body 231 is not restricted by the cover 239, the shield support part 230 moves further downward.

Thereafter, when the rotating cover 220 is further rotated in the same direction, the shield support part 230 is separated from the rotation axis 223, and the shield support part 230, the rotating cover part 220, and the closure part 210 are separated from each other.

Hereinafter, the configuration of the pumping unit that pumps the additive of the present invention from the additive tray 300 and provides it to the drinking water tray 100 will be described in detail.

The pumping unit 400 is installed in the drinking water tray 100 and the cover unit 200, and serves to pump the additives of the additive tray 300 and supply them to the internal space of the drinking water tray 100.

The pumping unit 400 is configured to move the additive by a fixed amount by the user's pumping, so that the amount of additive added can be adjusted according to the number of pumping times. The pumping unit 400 is configured to adjust the amount of additive added according to the number of pumping times. As shown, it is installed along the longitudinal direction of the cover unit 200 and the drinking water tray 100, and may be installed at a location adjacent to the inner surface of the drinking water tray 100.

In detail, the pumping unit 400 may be configured to include a pumping button unit 410 and a pumping unit 420.

The pumping button unit 410 is installed on the cover unit 200 to enable sliding and reciprocating movement, and is configured to move according to pressure from the user.

The pumping button unit 410 may be configured to include a stem unit 411, a guide bushing 413, and an airtight means 415.

The stem portion 411 is installed to be slidingly movable at the insertion hole of the drinking water tray 100, and the upper part is exposed to the outside of the drinking water tray 100 so that the user presses the upper part, and the lower part is applied to the pumping unit 420 by external force. It is configured to deliver.

The guide bushing 413 is shaped like a tube and guides the reciprocating stem part 411, which is inserted inside. The guide bushing 413 is inserted into the upper inner part of the airtight means 415. The guide bushing 413 may be configured to securely support the insertion hole by contacting the lower side of the flange portion formed at the upper end with the upper surface of the insertion hole.

The guide bushing 413 fixes the upper end of the airtight means 415 to the inner peripheral surface of the insertion hole through the flange part and reduces friction with the airtight means 415 when the stem part 411 moves in the vertical direction, thereby forming the airtight means 415. ) can provide the effect of preventing damage.

At this time, the pumping button unit 410 and the pumping unit 420 are divided into the outside and inside of the drinking water storage space by an airtight means 415 made of an elastically deformable soft membrane.

The airtight means 415 is formed in the shape of a cylindrical tube with the upper part open and the lower part closed, and the pumping button part 410 is inserted into the inner surface so that the lower surface of the pumping button part 410 is in contact with the bottom surface, The bottom surface is configured to contact the pumping unit 420.

The airtight means 415 may be composed of a bellows having a plurality of wrinkles formed along the circumferential direction on the outer peripheral surface so as to expand and contract in the vertical direction.

Accordingly, while the physical force can be transmitted, the drinking water in the drinking water storage space is prevented from leaking toward the pumping button unit 410.

Meanwhile, the pumping unit 420 is located in the drinking water storage space of the drinking water tray 100, rises and falls by the reciprocating movement of the pumping button unit 410, and connects the drinking water storage space and the additive storage space in communication, respectively. It serves to inhale the additive by rising and falling and discharge it into the drinking water storage space.

To this end, the pumping unit 420 may be configured to include a piston unit 430 and a discharge pipe 440.

The piston part 430 is located in the drinking water storage space, communicates with the additive tray 300, sucks the additive from the additive storage tray 300 by the reciprocating movement of the pumping button part 410, and It serves to discharge additives into the discharge pipe (440).

The piston unit 430 may include a piston rod 431, a piston housing 433, and an elastic member 435.

The piston rod 431 is linked with the pumping button part 410 and is raised and lowered by the reciprocating movement of the pumping button part 410, and is inserted into the inner space of the piston housing 433 to press the piston housing 433 during pumping. ) A flow path is formed inside so that the additives within can move.

The piston housing 433 is installed in an internal space so that the piston rod 831 goes up and down, a through hole is formed at the bottom to communicate with the additive tray 300, and the piston rod is coupled to the top.

Accordingly, the additive of the additive tray 300 flows into the piston housing 433 into the internal space due to a change in internal pressure as the piston rod 431 rises and falls.

And the discharge pipe 440 is a hollow pipe that extends in a 'U' shape from the end of the piston part 430, and discharges the pumped additive into the drinking water storage space.

In addition, the upper end ('U' shaped curved part) of the discharge pipe 440 is linked with the pumping button part 410, and is raised and lowered by the reciprocating movement of the pumping button part 410 to lift the piston part 430. Pressurize.

Meanwhile, the pumping unit 420 moves as additives flow into the pumping unit 420, so it needs to be cleaned after a certain period of use or when the additives are changed.

For this purpose, as shown in FIG. 6, an opening and closing plate 441 that can be opened and closed is provided on the upper surface ('U' shaped curved surface) of the discharge pipe 440, so that the opening and closing plate 441 is opened and closed when the pumping unit 420 is cleaned. By opening the plate 441, cleaning of the piston unit 430 and the discharge pipe 440 is facilitated.

In addition, it is desirable to separate the piston rod 431 and the elastic member 435 from the piston housing 433 when cleaning. For this purpose, the piston rod 431 is detachably coupled to the piston housing 433.

Specifically, the piston rod 431 is coupled with a fastening ring 451 that can be raised and lowered along the piston rod 431, and a fastening groove 460 is formed on the inner peripheral side of the upper end of the piston housing 433. This is formed.

And the piston rod 431 and the piston housing 433 are coupled by inserting the fastening protrusion 453 protruding on the side of the fastening ring 451 into the fastening groove 460 formed on the piston housing 433. do.

At this time, as shown in FIG. 6, the fastening groove 460 has an upper cut portion 461 formed by cutting to a size corresponding to the width of the fastening protrusion so that the fastening protrusion 453 can be inserted from the upper and outer side. ) and a horizontal slit 463 that extends in the horizontal direction from the lower end of the upper cut part 461 and allows the fastening protrusion 453 inserted into the upper cut part 461 to move by rotation, and the horizontal slit (463) The fastening protrusion 453, which extends upward from the end and moves along the horizontal slit 463, moves upward and is seated by the elastic force of the elastic member 435, so that rotational movement is limited. It is configured to include a seating portion 465.

When repeated pumping is performed with the piston rod 431 fastened to the piston housing 433, the vertical seating portion 465 is connected to the piston housing 433 and the piston rod 431. Maintains stability.

Specifically, when the piston rod 431 reciprocates by pumping, when the force pressing the discharge pipe 440 deviates from the center of the piston rod, eccentricity is generated, and such eccentricity is caused by the fastening ring 451. By generating a rotating force, there is a risk that the piston housing 433 and the piston rod 431 may be separated without the user's intention.

However, when the fastening protrusion 453 is seated on the vertical seating portion 465, the fastening ring 451 does not rotate even if a simple rotational force is generated in the fastening ring 451, so the piston housing 433 and the piston The rod 431 can be prevented from being separated.

Meanwhile, the elastic member 435 is located inside the piston housing 433 and is coupled to the piston rod 431, and serves to provide a restoring force so that the piston rod 431 can be pressed and moved downward and then moved upward. Do it.

Meanwhile, in the present invention, the through hole 437 penetrating the lower part of the piston housing 433 and the lower part of the drinking water tray 100 and the additive tray 300 are connected by the suction pipe module 500.

Hereinafter, the configuration of the suction pipe module that communicates the additive tray 300 and the drinking water tray 100 of the present invention will be described in detail.

As shown in FIG. 7, the suction pipe module 500 includes a coupling plate 510, an extension plate 520, a suction pipe 530, and an elastic cover 540.

The coupling plate 510 is formed in a disk shape so that the drinking water tray 100 is detachably coupled to the lower end, and an elastic cover 540 is coupled to the outer upper portion of the coupling plate 510. The elastic cover 540 is made of an elastic material to improve adhesion to the lower part of the drinking water tray 100.

At this time, the elastic cover 540 and the coupling plate 510 are coupled so that a predetermined space is formed between them.

And a disk-shaped extension plate 520 that is detachable by screwing is coupled to the lower center of the coupling plate 510.

In addition, the expansion plate 510 is configured to include a suction pipe 530 in the form of a circular tube. Accordingly, the suction pipe 530 penetrates the additive capsule 700 or the shielding cover 600, which will be described later, and the expansion plate ( 520) adheres closely to the penetration area and prevents additives from leaking to the outside.

To this end, the lower end of the extension plate 520 is formed with a protruding curved surface 521 whose lower surface protrudes in a curved shape around the central part to improve adhesion.

At this time, the coupling plate 510, the expansion plate 520, and the suction pipe 530 are formed with an inlet flow path through which the additive moves by communicating with the coupling plate 510, the expansion plate 520, and the suction pipe 530, and a through hole ( The additive is allowed to flow into the pumping unit 420 through 437).

Meanwhile, the suction pipe 530 may be formed as a tapered circular pipe whose width becomes slightly narrower downward.

In this case, when the suction pipe 530 penetrates the additive capsule 700 or the shielding cover 600, the deeper the penetration depth, the stronger the adhesion of the pipe area, thereby reducing the risk of additive leakage.

Additionally, an opening/closing ball valve 550 may be provided inside the coupling portion of the expansion plate 520 coupled to the coupling plate 510 to selectively open and close the additive inflow passage.

The open/close ball valve 550 selectively opens and closes the inlet flow path within the suction pipe 530 according to the rise and fall of the piston rod 431. When positive pressure is generated within the suction pipe 530, the open/close ball valve 550 ) rises and falls to open the inflow passage, and when negative pressure is generated, the opening/closing ball valve 550 descends to shield the inflow passage.

Accordingly, the inlet flow path creates a flow path only in the direction in which the additive flows toward the drinking water tray 100.

Hereinafter, the configuration of the additive tray that is coupled to the lower portion of the drinking water tray of the present invention and provides additives to the drinking water tray will be described in detail.

As shown in Figures 8 and 9, the additive tray 300 is open at the top and shielded at the bottom to form the additive storage space on the inside, and is screwed to the lower part of the drinking water tray 100. It is detachably coupled.

Meanwhile, in the present invention, the additive tray 300 can be divided into two embodiments depending on the operation type.

First, the first embodiment is an embodiment in which the additive tray 300 is used by directly filling the interior with additives.

In this case, there is a risk that the additive may leak out of the additive tray 300, so the present invention further includes a shielding cover 600.

The shielding cover 600 is intended to prevent the additives contained within the additive tray 300 from leaking out, and is formed as a disc made of an elastic material to be press-fitted onto the upper part of the additive tray 300.

At this time, a central through hole 610 through which the suction pipe 530 can pass is formed in the center of the shielding cover 600.

In addition, the central portion of the upper surface of the shielding cover 600 is formed with a concave surface 620 in a shape corresponding to the protruding curved surface 521 at the bottom of the expansion plate 520, which improves adhesion with the expansion plate 520. You can.

Meanwhile, it is preferable that the upper surface of the shielding cover 600 is provided with a grip part 630 that can be gripped when the shielding cover 600 is pulled out, to facilitate pulling out the shielding cover 600.

In addition, the shielding cover 600 may be configured to include a flow path cutout 650 that moves air in only one direction from the top to the bottom.

As shown in FIG. 8, the channel cut portion 650 may be formed as a pair of wings that are elastically stretched downward and face down the shielding cover 600. Accordingly, when negative pressure is generated in the lower part of the shielding cover 600, the air in the upper part of the shielding cover 600 moves downward through the flow path cut part 650, but the additive under the shielding cover 600 cuts the flow path. The portion 650 is prevented from moving upward.

When the flow path cut portion 650 is formed, even if a cutting surface is not formed in the suction pipe 530, a flow path is formed from the upper part of the shield cover 600 to the bottom, forming a part (F4) of the normal pressure flow path to be described later. can be configured.

Next, in the second embodiment of the additive tray, the additive tray 300 is used by inserting an additive capsule 700, which consists of a disposable container in which the additive is stored.

In this case, the additive tray 300 allows the user to conveniently use additives by inserting the additive capsule 720 containing the additive solution purchased from the manufacturer into the additive tray 300 without inserting the additive solution into the additive tray.

At this time, as shown in FIG. 9, the additive capsule 700 includes a container portion 710 in contact with the inner and bottom surfaces of the additive tray 300 and a cover film (710) that shields the upper surface of the container portion 710. 720).

The cover film 720 is a part punched by the pressure of the suction pipe 530 and is attached to the upper end of the container portion 710 by fusion with a soft synthetic resin film.

At this time, the side wall of the container unit 710 may include a protrusion on the upper portion of the outer peripheral surface that protrudes outward, and a step portion that is seated on the inner surface of the additive tray 300 may be formed at the boundary of the protrusion.

And, as shown enlarged in FIG. 9, a seating portion 730 is formed on the upper edge of the side wall of the container portion 710 for seating on the upper edge of the additive tray 300.

At this time, the seating portion 730 has a horizontal plate 731 extending in parallel outward from the top of the side wall to a distance corresponding to the thickness of the upper edge of the additive tray 300 and an end of the horizontal plate 731. It is configured to include a vertical plate 733 extending downward a predetermined distance, and the seating portion 730 surrounds the top of the additive tray 300 so that the additive capsule 700 is placed on the additive tray 300. It can be combined.

Meanwhile, looking at the state in which the additive tray 300 and the drinking water tray 100 are separated, in this case, the additive capsule 700 inserted into the additive tray 300 generates friction with the additive tray 300. At the same time, frictional force is generated with the suction pipe 530.

In this case, if the friction force between the additive capsule 700 and the suction pipe 530 is greater, the additive capsule 700 is attached to the suction pipe 530 and the additive tray 300 and the drinking water tray 100. is separated, and as a result, the risk of the additive capsule 700 falling to the floor or the additive leaking to the outside increases.

In order to prevent this, in the present invention, in order to improve the bonding force between the additive tray 300 and the additive tabule 700, a locking protrusion 750 and a locking protrusion are installed on the container portion 710 and the additive tray 300. 740) can be formed.

That is, as shown in FIG. 10, a locking protrusion 750 and a locking protrusion 740 are formed on the outer surface of the container unit 710 and the inner surface of the additive tray 300 at positions corresponding to each other when combined. When the additive tray 300 is separated from the drinking water tray 100, the locking protrusion 740 is supported on the locking protrusion 750 so that the additive capsule 300 is stably positioned within the additive tray 300. can do.

On the other hand, when the locking protrusion 750 is formed on the inner surface of the additive tray 300, the locking protrusion is seated on the outer peripheral surface of the shielding cover 600 inserted into the additive tray 300, and the shielding cover 600 It can also play a role in supporting the insertion position.

And when the additive tray 300 and the drinking water tray 100 are screwed together, the outer side of the elastic cover 540 is located between the upper surface of the additive tray 300 and the outer lower surface of the drinking water tray 100.

Accordingly, the outside of the elastic cover 540 made of the elastic material is pressed by the screw coupling force of the additive tray 300 and the drinking water tray 100, thereby improving the sealing force of the inner space of the additive tray 300.

Meanwhile, regardless of the embodiment of the additive tray 300, the additive tray 300 shields the upper part of the additive tray 300 in a state in which the additive tray 300 is separated from the drinking water tray 100. Therefore, it may be configured to further include an additive tray cover portion 800 to ensure independent portability of the additive tray.

The additive tray cover 800 is a cover of the additive tray 300, is screwed to the additive tray 300, and has a hole or shielding cover 600 on the upper part of the additive capsule 700 at the center of the inner side. In order to shield the through hole, a pressing protruding surface 810 may be formed that protrudes downward in a hemispherical shape with a curved surface.

Accordingly, the additive tray 300 can be safely carried and stored separately from the drinking water tray 100.

In the present invention, as the additives in the additive tray 300 are pumped through the pumping unit 400 and supplied to the drinking water storage space, a negative pressure is formed inside the additive tray 300, so the additives are not pumped smoothly, and this causes As a result, the amount of additives flowing out per one pumping decreases, making it difficult to produce a fixed amount of mixed drinks as the discharge amount becomes non-uniform. Furthermore, when replacing the additive tray 300, it is opened by the internal pressure of the additive storage space. This can be difficult.

Accordingly, it is preferable that the additive tray according to the present invention configures an atmospheric pressure passage through which, when negative pressure is generated, external air flows in to maintain the pressure inside the additive tray at normal pressure.

Hereinafter, when additives are pumped from the additive tray 300 of the present invention, the normal pressure flow path structure that maintains the normal pressure inside the additive tray will be described in detail.

In the present invention, for convenience of explanation, the atmospheric pressure passage will be divided into four stages, from the first to the fourth normal pressure passage.

First, the first normal pressure passage (F1) refers to a passage through which external air can flow from the outside into the joint space between the lower portion of the drinking water tray and the additive tray.

And, the second normal pressure passage (F2) refers to a passage that communicates with the first normal pressure passage (F1) and allows the inflow of external air to flow into the space between the elastic cover and the coupling plate.

In addition, the third normal pressure passage (F3) refers to a passage that communicates with the second normal pressure passage and allows the inflowed external air to move into the inner space of the additive tray below the coupling plate.

Lastly, the fourth normal pressure passage (F4) is in communication with the third normal pressure passage (F3) and refers to a passage that allows the air in the inner space of the additive tray to move into the additive capsule.

That is, in the present invention, the atmospheric pressure oil channel is composed of a combination of the first to fourth atmospheric pressure oil channels. Depending on the implementation configuration of each detailed atmospheric pressure oil channel, the normal pressure oil channel of the present invention is largely divided into three types.

Below, we will look at each embodiment of the normal pressure oil path in detail.

First, in the first embodiment of the normal pressure flow path, as shown in FIG. 12, external air flows into the space between the elastic cover 540 and the drinking water tray 100 through the inlet hole 110 on the side of the drinking water tray 100. flows in (F1), and the introduced air moves (F2) between the elastic cover 540 and the coupling plate 510 through the vertical communication hole 545 of the elastic cover 540, and the moved air moves through the elastic cover 540. After moving (F3) to the lower part of the coupling plate 510 through the button 560, the lower part of the shielding cover 600 or the additive capsule ( 700) This is a flow path that moves inward (F).

For this purpose, as shown in FIG. 13, an inlet hole 110 for introducing external air is formed at the space between the elastic cover 540 and the lower end of the drinking water tray 100 on the side of the drinking water tray 100. do.

In addition, the elastic cover 540 of the suction pipe module 500 is located on the upper surface of the elastic cover 540 or the outer lower surface of the drinking water tray 100 in order to form a separation space on the outside between the lower ends of the drinking water tray 100. One partial surface is formed as a stepped surface or an inclined surface (see FIG. 16).

And in order to form the second normal pressure passage (F2), the elastic cover 540 includes a space between the elastic cover 540 and the lower part of the drinking water tray 100 and the lower part of the elastic cover 540 and the coupling. A vertical communication hole 545 is formed to communicate the space between the plates 510 (see FIG. 16).

Meanwhile, the coupling plate 510 is provided with an elastic button 560 to form the third normal pressure passage F3. It is a type of pressure valve that is elastically deformed and opens and closes selectively.

In the present invention, in order to form a fourth normal pressure passage, a passage groove 523 is formed in the coupling plate 510, and a cutting surface 531 is formed at the upper end of the suction pipe 530.

The flow groove 523 is formed from the outer end of the protruding curved surface 521 of the expansion plate 520 to the center, forming a flow path for air to move on the close contact surface of the expansion plate 520, and the cutting surface ( 531) is formed by cutting the outer peripheral surface of the circular suction pipe 530, and is formed to a predetermined length downward from the end of the flow groove 523, thereby forming a space in the through surface of the suction pipe 530.

Next, in the second embodiment of the normal pressure flow path, as shown in FIG. 14, external air flows in through the joint between the drinking water tray 100 and the participation tray 300, and forms a spaced groove ( 541) and flows into the space between the elastic cover 540 and the drinking water tray 100 (F1), and the introduced air flows into the elastic cover 540 through the vertical communication hole 545 of the elastic cover 540. and the coupling plate 510 (F2), and the moved air moves (F3) to the lower part of the coupling plate 510 through the elastic button 560, and then flows through the flow groove 525 of the expansion plate 520 and the suction pipe. It is a flow path that moves (F4) along the cutting surface of (530) below the shielding cover (600) or inside the additive capsule (700).

For this purpose, a separation space is formed between the coupling surface and the coupling end of the drinking water tray 100 and the additive tray 300, and external air flows in through the separation space.

At this time, the introduced air must pass through the lower inner surface of the drinking water tray and the outer surface of the elastic cover and flow into the space between the elastic cover 540 and the drinking water tray 100 (F1). For this purpose, Figure 16 As shown, a separation groove 541 through which external inflow air can move is formed on some of the joint surfaces of the lower inner surface of the drinking water tray 100 and the outer surface of the elastic cover 540.

Hereinafter, since the second normal pressure oil passage (F2), the third normal pressure oil passage (F3), and the fourth normal pressure oil passage are the same as the first embodiment of the above-mentioned normal pressure oil passage, detailed description will be omitted.

Meanwhile, looking at the separation space formed between the coupling surface and the coupling end of the drinking water tray 100 and the additive tray 300, the separation space formed between the coupling end of the drinking water tray 100 and the additive tray 300 is , It may be formed by a step at a coupled end of the drinking water tray 100 and the additive tray 300.

That is, the length of the coupling part of the additive tray 300 is longer than the length of the coupling part of the drinking water tray 100 to form a spaced apart space.

At this time, since the additive tray 300 is provided with an elastic cover 540 on the upper coupling surface, the coupling step is determined by the height of the screw connection on the upper outer side of the additive tray 300 and the height of the outer surface of the elastic cover 540. It is formed by the difference value obtained by subtracting (-) the length of the screw connection height inside the lower portion of the drinking water tray 100 from the total length.

In this case, when the additive tray 300 and the drinking water tray 100 are joined together with a relatively large force, the coupling gap is reduced.

Meanwhile, the coupling step must allow air to flow while maintaining a stable coupling force between the additive tray 300 and the drinking water tray 100. It also varies depending on screw coupling, so it is preferably approximately 1 to 10 mmm. do.

And the separation space formed between the coupling surface of the drinking water tray 100 and the additive tray 300 is formed by the gap between the coupling threads of the drinking water tray 100 and the additive tray 300.

At this time, the gap between the engaging screw threads may be formed by the space between the screw threads, or as shown in FIG. 15, a part of the screw thread may be removed to form an upward gap.

That is, as shown in Figure 15, the coupling end of the drinking water tray 100 and the additive tray 300 is finely cut into the separation space formed between the coupling end of the drinking water tray 100 and the additive tray 300. It may be formed by one or more inlet incisions 120 that are formed.

mind

Finally, in the third embodiment of the normal pressure flow path, as shown in FIG. 17, external air flows in through the joint between the drinking water tray 100 and the participation tray 300, and is connected to the side of the elastic cover 540 and the drinking water tray. (100) flows into the space between the inner sides (F1), and the introduced air moves between the elastic cover 540 and the coupling plate 510 through the horizontal communication hole 545 of the elastic cover 540 (F2) ), and after the moved air moves to the lower part of the coupling plate 510 through the elastic button 560 (F3), the shielding cover is applied along the flow groove 525 of the expansion plate 520 and the cut surface of the suction pipe 530. (600) It is a flow path that moves (F) to the lower part or inside the additive capsule (700).

Since the separation space formed between the coupling surface and coupling end of the drinking water tray 100 and the additive tray 300 is the same as the second embodiment of the above-described normal pressure flow path, detailed description will be omitted.

Meanwhile, the air flowing into the space between the side of the elastic cover 540 and the inside of the side of the drinking water tray 100 is connected to the elastic cover 540 and the coupling plate through the horizontal communication hole 545 of the elastic cover 540.
