Description

[Technical field]

[0001] The present invention relates to a water server. [Background technology]

[0002] Conventionally, water servers have been used mainly in offices and hospitals, but in recent years, water servers are becoming more common in ordinary homes due to growing interest in water safety and health. For example, the water server described in Patent Document 1 is known.

[0003] The water server in Patent Document 1 has a housing, a cold water tank and a hot water tank arranged inside the housing, a cold water outlet conduit for discharging cold water from the cold water tank to the outside of the housing, a cold water lever that the user swings to discharge cold water, a hot water outlet conduit for discharging hot water from the hot water tank to the outside of the housing, and a hot water lever that the user swings to discharge hot water. A cold water on-off valve that is opened and closed by the cold water lever is provided midway through the cold water outlet conduit, and a hot water on-off valve that is opened and closed by the hot water lever is provided midway through the hot water outlet conduit.

[0004] The hot water on-off valve has a hot water valve body that is movable up and down between a closed position where the hot water outlet is closed by sitting on a valve seat provided in the hot water outlet passage and an open position where the hot water outlet passage is opened by moving upward from the valve seat, a hot water valve rod that moves up and down integrally with the hot water valve body, and a valve spring that presses the hot water valve rod downward. The hot water valve rod has a part that protrudes upward from the upper plate of the valve housing that contains the hot water valve body, and a hot water lever is connected to this part via a lever pin. When the hot water lever is swung, the lever pin moves upward in conjunction with the swing of the hot water lever, and the hot water valve rod moves upward integrally with the lever pin, causing the hot water valve body to move upward from the valve seat, opening the hot water outlet passage and allowing hot water to flow out.

[0005] Furthermore, the water server in Patent Document 1 is provided with a child lock mechanism to prevent a small child from accidentally operating the hot water lever to cause hot water to flow and resulting in a burn accident.

[0006] This child lock mechanism has a child lock member that is movable between a child lock position that prohibits the discharge of hot water and a child lock release position that allows the discharge of hot water, and a lock spring that urges the child lock member from the child lock release position toward the child lock position.

[0007] When the child lock member is in the child lock position, the child lock member engages with a horizontal groove formed in a portion of the hot water valve stem that protrudes upward from the top plate of the valve housing, thereby preventing the hot water valve stem from moving up and down. At this time, because the hot water valve stem is prevented from moving up and down, the lever pin fixed to the hot water valve stem is also prevented from moving up and down, preventing the hot water lever from swinging (i.e., the hot water lever does not swing even if the user presses the hot water lever). On the other hand, when the child lock member is in the child lock release position, the child lock member releases its engagement with the horizontal groove of the hot water valve stem, thereby allowing the hot water valve stem to move up and down. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2014-166862 A Summary of the Invention [Problem to be solved by the invention]

[0009] In the child lock mechanism of Patent Document 1, when the child lock member is in the child lock position, even if the user presses the hot water lever, the hot water lever should not swing and hot water should not come out.

[0010] However, it has been found that in rare cases, when a user presses the hot water lever, the hot water lever may swing and cause hot water to come out, even when the child lock member is in the child lock position.

[0011] That is, in the child lock mechanism of Patent Document 1, when the child lock member is in the child lock position (i.e., when hot water is prohibited from being discharged), if the user presses the hot water lever, the force pressing the hot water lever is transmitted to the hot water valve rod via the lever pin, but since the child lock member is engaged with the horizontal groove of the hot water valve rod, this engagement prevents the hot water valve rod from moving upward, and the hot water valve rod should not move upward. However, due to wear of the child lock member or wear of the horizontal groove of the hot water valve rod, the engagement of the child lock member with the horizontal groove of the hot water valve rod may become shallow, and in this case, if the user forcibly presses the hot water lever, the force transmitted from the hot water lever to the hot water valve rod via the lever pin may disengage the child lock member from the horizontal groove of the hot water valve rod, resulting in the hot water lever swinging and the hot water valve rod moving upward, which may cause hot water to be discharged.

[0012] The problem to be solved by the present invention is to provide a water server capable of effectively preventing burns to small children. [Means for solving the problem]

[0013] In order to solve the above problems, the present invention provides a water server having the following configuration. [Configuration 1] A housing and A hot water tank disposed inside the housing; a hot water outlet channel for discharging hot water from the hot water tank to the outside of the housing; a hot water valve body that is movable up and down between a valve closing position where the hot water outlet passage is closed by being seated on a valve seat provided in the hot water outlet passage and a valve opening position where the hot water outlet passage is opened by being moved upward away from the valve seat; A hot water valve rod that moves up and down integrally with the hot water valve body; A hot water lever that is swung by a user to dispense hot water; A water server having a child lock member movable between a child lock position that prohibits hot water from being dispensed and a child lock release position that allows hot water to be dispensed, A vertically movable member that is provided so as to be vertically movable independently of the hot water valve rod and that moves vertically in conjunction with the swinging of the hot water lever when the hot water lever is swung; A water server characterized in having a connecting member that connects the up and down moving member and the hot water valve rod so that the up and down movement of the up and down moving member is transmitted to the hot water valve rod when the child lock member is in the child lock release position, and a connecting member that disconnects the up and down moving member and the hot water valve rod so that the up and down movement of the up and down moving member is not transmitted to the hot water valve rod when the child lock member is in the child lock position.

[0014] With this configuration, when the child lock member is in the child lock position, when the user presses the hot water lever, the hot water lever swings, and the vertically movable member moves upward in conjunction with the swinging of the hot water lever, but because the connection between the vertically movable member and the hot water valve rod by the connecting member is released, the hot water valve rod does not move upward and hot water does not come out. In other words, the force pressing the hot water lever is not transmitted to the hot water valve rod, resulting in an idling state, which prohibits the discharge of hot water. On the other hand, when the child lock member is in the child lock release position, the hot water valve rod and the vertically movable member are connected by the connecting member, so when the user swings the hot water lever and the vertically movable member moves upward in conjunction with the swinging of the hot water lever, the hot water valve rod moves upward together with the vertically movable member, and hot water comes out.

[0015] In this way, when the child lock member is in the child lock position (i.e., when the discharge of hot water is prohibited), the discharge of hot water is not prohibited by preventing the swing of the hot water lever, but rather, the swing of the hot water lever is allowed, while the force of the user pressing the hot water lever is not transmitted to the hot water valve rod, thereby prohibiting the discharge of hot water. Therefore, the child lock function that prohibits the discharge of hot water is reliable and it is possible to effectively prevent scalding accidents involving small children.

[0016] [Configuration 2] the connecting member is held by the child lock member so as to move integrally with the child lock member when the child lock member is moved between the child lock position and the child lock release position; The connecting member has a first engagement portion that engages with the vertical moving member and a second engagement portion that engages with the hot water valve rod, The water server described in configuration 1, wherein when the child lock member is in the child lock release position, the first engagement portion engages with the up-down moving member and the second engagement portion engages with the hot water valve rod, and when the child lock member is in the child lock position, at least one of the engagement of the first engagement portion and the engagement of the second engagement portion is released.

[0017] With this configuration, when the child lock member is in the child lock release position (i.e. when hot water is allowed to flow), the first engagement portion and the second engagement portion of the connecting member engage with the vertically movable member and the hot water valve rod, respectively, and this engagement connects the vertically movable member and the hot water valve rod. In this state, when the user presses the hot water lever to swing it, the force with which the user presses the hot water lever is transmitted to the hot water valve rod via the vertically movable member and the connecting member, causing the hot water valve rod to move upward.

[0018] [Configuration 3] The vertically movable member is formed with a first horizontal groove in a horizontal direction with which the first engagement portion is engaged, The water server according to configuration 2, wherein the hot water valve rod has a second horizontal groove formed in a horizontal direction with which the second engagement portion engages.

[0019] When this configuration is adopted, when the child lock member is in the child lock release position (i.e., when hot water is allowed to flow out), the first engagement portion of the connecting member engages with the first horizontal groove of the up-down moving member, and the second engagement portion of the connecting member engages with the second horizontal groove of the hot water valve rod, thereby connecting the up-down moving member and the hot water valve rod.

[0020] [Configuration 4] The water server according to any one of configurations 1 to 3, wherein the connecting member is provided so as to be movable up and down relative to the child lock member.

[0021] With this configuration, since the connecting member can move up and down relative to the child lock member, when the connecting member moves up and down together with the vertically movable member and the hot water valve rod, the child lock member does not need to move up and down. Therefore, it is possible to move the child lock member between the child lock position and the child lock release position by only a simple linear movement.

[0022] [Configuration 5] A return spring that presses the vertical moving member downward and a valve spring that presses the hot water valve rod downward, The water server according to any one of configurations 1 to 4, wherein the force with which the return spring presses the vertically movable member downward is set to be smaller than the force with which the valve spring presses the hot water valve stem downward.

[0023] With this configuration, when the user swings the hot water lever to release hot water, the hot water lever swings against the forces of both the return spring that presses the vertically moving member downward, and the valve spring that presses the hot water valve rod downward, but because the force of the return spring is set small, it is possible to set the force of the valve spring to be larger accordingly. This allows the hot water valve body to seat on the valve seat with a large force, reliably preventing hot water dripping when the hot water lever is not being operated.

[0024] [Configuration 6] The hot water lever has a lever body extending vertically through the rear side of a valve housing that accommodates the hot water valve body, a forward extension portion extending forward from an upper end of the lever body through the upper side of the valve housing, a swing fulcrum portion formed at a lower front end of the forward extension portion, and a lever pin horizontally fixed to a portion of the forward extension portion rearward of the swing fulcrum portion, The hot water valve rod has a portion protruding upward from the upper plate of the valve housing, and a hollow cylindrical portion that accommodates the vertically movable member so as to be vertically movable is formed in the portion of the hot water valve rod that protrudes upward from the upper plate of the valve housing, The hollow cylindrical portion of the hot water valve rod has a vertical long hole through which the lever pin passes horizontally, 6. The water server according to any one of configurations 1 to 5, wherein the vertically movable member is supported by the lever pin so as to move vertically integrally with the lever pin when the hot water lever is swung. Effect of the Invention

[0025] The water server of this invention, when the child lock member is in the child lock position (i.e., when the discharge of hot water is prohibited), does not prohibit the discharge of hot water by preventing the swing of the hot water lever, but rather prohibits the discharge of hot water by allowing the hot water lever to swing, but by creating an idle state in which the force of the user pressing the hot water lever is not transmitted to the hot water valve rod, thereby ensuring a reliable child lock function that prohibits the discharge of hot water and effectively preventing scalding accidents among small children.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] A water server according to an embodiment of the present invention is shown in Figure 1. This water server has a housing 1, a cold water outlet 2 and a hot water outlet 3 located on the front side of the housing 1, a cold water lever 4 that the user swings to dispense cold water, and a hot water lever 5 that the user swings to dispense hot water.

[0028] As shown in Fig. 2, a cold water tank 6 and a hot water tank 7 are arranged inside the housing 1. The cold water tank 6 is connected to a replaceable water bottle 9 (see Fig. 1) via a water supply pipe 8, so that when the amount of cold water in the cold water tank 6 decreases, drinking water is supplied from the water bottle 9 to the cold water tank 6 via the water supply pipe 8. A water supply pump (not shown) is provided midway along the water supply pipe 8.

[0029] A cooling device 10 that cools the drinking water contained in the cold water tank 6 is attached to the cold water tank 6. The drinking water in the cold water tank 6 is kept at a predetermined low temperature (for example, below 10°C) by the cooling device 10. A cold water outlet conduit 11 that communicates between the cold water tank 6 and the cold water outlet 2 is connected to the bottom of the cold water tank 6. A cold water on-off valve 12 is provided midway along the cold water outlet conduit 11, and by swinging the cold water lever 4 backward (to the right in the figure), the cold water on-off valve 12 opens, making it possible to discharge cold water (low-temperature drinking water) from the cold water tank 6 to the outside of the housing 1.

[0030] The hot water tank 7 is disposed below the cold water tank 6. The hot water tank 7 and the cold water tank 6 are connected via a tank connecting pipe 13, and drinking water is introduced from the cold water tank 6 to the hot water tank 7 through the tank connecting pipe 13. A heating device 14 that heats the drinking water contained in the hot water tank 7 is attached to the hot water tank 7. The drinking water in the hot water tank 7 is kept at a predetermined high temperature (for example, 80°C or higher) by the heating device 14.

[0031] A hot water outlet conduit 15 that communicates between the hot water tank 7 and the hot water outlet 3 (see FIG. 1) is connected to the top surface of the hot water tank 7. A hot water on-off valve 16 (see FIG. 3 and FIG. 4) is provided midway along the hot water outlet conduit 15, and by opening this hot water on-off valve 16, it is possible to discharge hot water (high-temperature drinking water) from the hot water tank 7 to the outside of the housing 1.

[0032] As shown in Figure 4, the hot water on-off valve 16 has an annular valve seat 17 provided midway through the hot water outlet passage 15, a hot water valve body 18 provided so as to be movable up and down between a closed position (position shown in Figure 4) in which it seats on the valve seat 17 to close the hot water outlet passage 15 and an open position (position shown in Figure 14) in which it moves upward from the valve seat 17 to open the hot water outlet passage 15, a hot water valve rod 19 that moves up and down integrally with the hot water valve body 18, a valve housing 20 that accommodates the hot water valve body 18 so as to be movable up and down, and a valve spring 21 that urges the hot water valve body 18 toward the closed position.

[0033] The valve spring 21 is a compression coil spring. The upper end of the valve spring 21 is supported by the upper plate 22 of the valve housing 20, and the lower end of the valve spring 21 presses the hot water valve rod 19 downward, and the pressing force presses the hot water valve body 18 against the valve seat 17. The valve seat 17 is formed in an annular shape so as to surround the hot water outlet passage 15. The hot water valve rod 19 is inserted into a through hole 23 in the vertical direction formed in the upper plate 22 of the valve housing 20. The hot water valve body 18 is fixed to the lower end of the hot water valve rod 19. A stem holder 24 is attached to the upper side of the valve housing 20 to support the outer periphery of the part of the hot water valve rod 19 that protrudes upward from the upper plate 22 of the valve housing 20 so as to be movable up and down.

[0034] The hot water lever 5 has a lever body 25 that extends vertically through the rear side of the valve housing 20 (to the right in the figure), a forward extension 26 that extends forward (to the left in the figure) from the upper end of the lever body 25 through the upper side of the valve housing 20, a swing fulcrum part 27 formed at the lower front end of the forward extension part 26, and a lever pin 28 fixed horizontally to a part of the forward extension part 26 behind the swing fulcrum part 27. The swing fulcrum part 27 is a part that comes into contact with the upper surface of the upper plate 22 of the valve housing 20 and serves as the swing fulcrum of the hot water lever 5 when the hot water lever 5 is pressed backward (to the right in the figure) to swing it, as shown in Figure 14.

[0035] As shown in Fig. 5, the hot water on-off valve 16 is provided with a child lock mechanism 30. The child lock mechanism 30 has a child lock member 31 supported so as to be movable in the front-rear direction (left-right direction in the drawing) between a child lock position (position shown in Fig. 5) that prohibits hot water from being discharged and a child lock release position (position shown in Fig. 12) that allows hot water to be discharged, a vertically moving member 32 that moves up and down in conjunction with the swinging of the hot water lever 5 when the hot water lever 5 is swung, and a connecting member 33 that can connect the vertically moving member 32 and the hot water valve rod 19.

[0036] The child lock member 31 is supported in an accommodating recess 34 formed in the stem holder 24 so as to be movable in the front-rear direction. The child lock member 31 is biased by a lock spring 35 from a child lock release position (position shown in FIG. 12) to a child lock position (position shown in FIG. 5). The child lock member 31 has an unlock button 36 that can be pressed from the front side of the housing 1. When the user presses the unlock button 36, the child lock member 31 retreats from the child lock position (position shown in FIG. 5) to the child lock release position (position shown in FIG. 12). On the other hand, when the user releases the pressure on the unlock button 36, the biasing force of the lock spring 35 causes the child lock member 31 to elastically return from the child lock release position (position shown in FIG. 12) to the child lock position (position shown in FIG. 5).

[0037] The vertically moving member 32 is a rod-shaped member extending in the vertical direction, and is arranged side by side on the same axis as the hot water valve rod 19. The vertically moving member 32 is housed in a hollow cylinder portion 37 formed in a portion of the hot water valve rod 19 that protrudes upward from the upper plate 22 of the valve housing 20 so as to be vertically movable, and this allows the vertically moving member 32 to move vertically independently of the hot water valve rod 19 (i.e., when the hot water valve rod 19 is stopped without moving vertically, only the vertically moving member 32 can move vertically).

[0038] The vertically movable member 32 is pressed downward by a return spring 38. The return spring 38 is assembled in a vertically compressed state between the vertically movable member 32 and a stem holder cover 39 attached to the stem holder 24. The force with which the return spring 38 presses the vertically movable member 32 downward is set to be smaller than the force with which the valve spring 21 presses the hot water valve rod 19 downward. As shown in FIG. 9, a rotation prevention protrusion 41 is formed on the outer periphery of the vertically movable member 32 to engage with a rotation prevention groove 40 formed in the hollow cylinder portion 37 of the hot water valve rod 19 and extending in the vertical direction.

[0039] As shown in FIG. 8, the forward extension 26 of the hot water lever 5 has a pair of opposing walls 42 that face each other in the left-right direction with the hollow cylinder 37 of the hot water valve rod 19 therebetween, and the left and right ends of the lever pin 28 are inserted and fixed into pin holes 43 formed in each of the pair of opposing walls 42. The hollow cylinder 37 of the hot water valve rod 19 has a vertical long hole 44 through which the lever pin 28 passes horizontally. The vertical length of the long hole 44 is equal to or longer than the vertical movement distance of the lever pin 28 when the hot water lever 5 is swung. The vertical movement member 32 is supported by the lever pin 28 so as to move vertically together with the lever pin 28 when the hot water lever 5 is swung.

[0040] 6, the connecting member 33 is housed in a vertically extending accommodating tube portion 45 formed in the child lock member 31 so as to be movable up and down. As a result, when the child lock member 31 is moved forward and backward between the child lock position and the child lock release position, the connecting member 33 is held by the child lock member 31 so as to move integrally with the child lock member 31, and is movable up and down relative to the child lock member 31. In the figure, an example in which the unlock button 36 of the child lock member 31 and the accommodating tube portion 45 are formed integrally with each other is shown, but they may be formed separately.

[0041] As shown in Figs. 8 and 10, the connecting member 33 has a first engagement portion 46 that engages with the vertically movable member 32 and a second engagement portion 47 that engages with the hot water valve rod 19. A first horizontal groove 48 that engages with the first engagement portion 46 is formed on the outer periphery of the part of the vertically movable member 32 that protrudes upward from the hollow cylinder portion 37 of the hot water valve rod 19. A second horizontal groove 49 that engages with the second engagement portion 47 is formed on the upper outer periphery of the hollow cylinder portion 37 of the hot water valve rod 19. The first engagement portion 46 is a pair of protrusions formed on both sides that sandwich the vertically movable member 32 therebetween, and the second engagement portion 47 is a pair of protrusions formed on both sides that sandwich the hollow cylinder portion 37 of the hot water valve rod 19 therebetween.

[0042] Here, as shown in Figs. 12 and 13, when the child lock member 31 is in the child lock release position, the first engagement portion 46 shown in Fig. 8 engages with the first horizontal groove 48 of the vertically moving member 32, and the second engagement portion 47 engages with the hot water valve rod 19, and the vertically moving member 32 and the hot water valve rod 19 are connected by the connecting member 33 so that the vertical movement of the vertically moving member 32 is transmitted to the hot water valve rod 19 by the engagement of the two. On the other hand, as shown in Fig. 6, when the child lock member 31 is in the child lock position, the engagement between the first engagement portion 46 and the first horizontal groove 48 is released, and this release of engagement releases the connection between the vertically moving member 32 and the hot water valve rod 19 so that the vertical movement of the vertically moving member 32 is not transmitted to the hot water valve rod 19. Note that, as shown in Fig. 7, the second engagement portion 47 maintains a state of being engaged with the second horizontal groove 49 even when the child lock member 31 is in the child lock position.

[0043] Examples of how to use this water server will be explained.

[0044] As shown in Figure 11, when the user presses the hot water lever 5 without pressing the unlock button 36 (i.e., when the child lock member 31 is in the child lock position), the hot water lever 5 swings backward, and the vertically movable member 32 moves upward in conjunction with the swing of the hot water lever 5, but because the connection between the vertically movable member 32 and the hot water valve rod 19 by the connecting member 33 has been released, the hot water valve rod 19 does not move upward and hot water does not come out. In other words, the force pressing the hot water lever 5 is not transmitted to the hot water valve rod 19, creating an idling state, and hot water is prohibited from coming out.

[0045] On the other hand, as shown in Figure 14, when the user presses the hot water lever 5 with the unlock button 36 pressed in (i.e., the child lock member 31 is in the child lock release position), the hot water lever 5 swings backward, and the vertically moving member 32 moves upward in conjunction with the swinging of the hot water lever 5. At this time, because the hot water valve rod 19 and the vertically moving member 32 are connected by the connecting member 33, the hot water valve rod 19 moves upward together with the vertically moving member 32, and hot water comes out.

[0046] As shown in Figure 11, when the child lock member 31 is in the child lock position (i.e., when the discharge of hot water is prohibited), this water server does not prohibit the discharge of hot water by preventing the swing of the hot water lever 5, but rather prohibits the discharge of hot water by allowing the hot water lever 5 to swing, but by creating an idle state in which the force exerted by the user pressing the hot water lever 5 is not transmitted to the hot water valve rod 19. Therefore, the child lock function that prohibits the discharge of hot water is reliable and it is possible to effectively prevent burns to small children.

[0047] In addition, in this water server, when the child lock member 31 is in the child lock release position as shown in FIG. 12 (i.e., when hot water is allowed to flow), the first engagement portion 46 and the second engagement portion 47 of the connecting member 33 shown in FIG. 8 engage with the vertically movable member 32 and the hot water valve rod 19, respectively, and the vertically movable member 32 and the hot water valve rod 19 are connected by this engagement. In this state, when the user presses the hot water lever 5 to swing the hot water lever 5 as shown in FIG. 14, the force with which the user presses the hot water lever 5 is transmitted to the hot water valve rod 19 via the vertically movable member 32 and the connecting member 33, and the hot water valve rod 19 moves upward. At this time, the hot water lever 5 swings against the forces of both the return spring 38 that presses the vertically movable member 32 downward and the valve spring 21 that presses the hot water valve rod 19 downward, but since the force of the return spring 38 is set to be small, the force of the valve spring 21 can be set to be large accordingly. Therefore, as shown in FIG. 4, when hot water is not being discharged, the hot water valve body 18 can be seated on the valve seat 17 with a large force, reliably preventing hot water from dripping when the hot water lever 5 is not being operated.

[0048] In addition, in this water server, as shown in Fig. 8, the connecting member 33 is provided so as to be vertically movable relative to the child lock member 31, so that the child lock member 31 does not need to move vertically when the connecting member 33 moves vertically together with the vertically movable member 32 and the hot water valve rod 19. Therefore, as shown in Fig. 14, the child lock member 31 can be moved between the child lock position and the child lock release position simply by linearly moving it forward and backward.

[0049] In each of the above embodiments, as shown in FIG. 1 , an exchangeable bottle type water server has been described as an example in which water from an exchangeable water bottle 9 filled with drinking water is introduced into the cold water tank 6 and hot water tank 7 for use. However, the present invention can be similarly applied to a purified water type water server in which raw water such as tap water is filtered with a water purification filter cartridge to produce purified water, and the purified water is introduced into the cold water tank 6 and hot water tank 7 for use.
