Description

The present invention relates to a keyed water server that makes it possible to prevent infant burns extremely effectively.

Conventionally, water servers have been used mainly in offices and hospitals, but in recent years, due to growing interest in water safety and health, water servers are becoming widespread in ordinary households. A water server usually includes a housing, a chilled water tank housed inside the housing, a chilled water pouring path for pouring cold drinking water in the chilled water tank to the outside of the housing, and a chilled water pouring path. It has a cold water pouring valve that opens and closes the water, and a cold water pouring operation unit that the user operates to open the cold water pouring valve, and cold water is used by operating this cold water pouring operation unit. Can be done.

The water server includes a hot water tank housed inside the housing, a hot water pouring path for pouring hot drinking water in the hot water tank to the outside of the housing, and hot water pouring that opens and closes the hot water pouring path. It further has a valve and a hot water pouring operation unit operated by the user to open the hot water pouring valve, and hot water can be used by operating this hot water pouring operation unit. There are many things that have become.

By the way, in the type of water server where hot water can be used, a child lock function is provided in order to prevent an infant from inadvertently operating the water server to pour out hot water. The child lock function is a combination of two or more operations for pouring hot water from the water server so that the hot water is not easily poured even if the infant operates it. (For example, Patent Document 1).

However, even if the child lock function is provided, the operation of pouring hot water happens to be established while the infant operates various operations, or the operation performed when an adult pours hot water is performed. There was a problem that the risk of the infant pouring hot water and getting burned could not be completely eliminated because the infant could see and imitate it.

In other words, the more complicated the operation for pouring hot water, the stronger the child lock function can be, and the more effectively the child's burn accident can be prevented, but on the other hand, the user. The operation when an adult is pouring hot water becomes complicated, and the convenience of the water server is sacrificed. Therefore, there is a limit to strengthening the child lock function, and it is difficult to completely eliminate the risk of the infant pouring hot water only by the child lock function.

Japanese Unexamined Patent Publication No. 2014-166682

The problem to be solved by the present invention is to provide a water server capable of extremely effectively preventing a burn accident of an infant.

In order to solve the above problems, the inventor of the present application provides a water server having the following configuration.
With the housing
A hot water tank arranged inside the housing and
A hot water injection path for pouring hot drinking water in the hot water tank to the outside of the housing,
A hot water injection valve that opens and closes the hot water injection path,
The valve opening allowable position that allows the valve body of the hot water injection valve to move from the valve closing position to the valve opening position, and the valve body of the hot water injection valve moving from the valve closing position to the valve opening position. A valve opening blocking member provided so as to be movable between the valve opening blocking position and the valve opening blocking position.
A child lock release button operated by the user to move the valve opening blocking member from the valve opening blocking position to the valve opening allowable position.
A key member configured to be portable independently of the housing,
The valve opening blocking member moves from the valve opening blocking position to the valve opening allowable position by having an insertion port into which the key member is inserted and operating the key member inserted into the insertion port. A switch member that moves between a normal child lock position that allows the valve opening and a complete child lock position that prevents the valve opening blocking member from moving from the valve opening blocking position to the valve opening allowable position.
A water server with a key.

In this way, since the key member is configured to be portable independently of the housing, the key member can be stored in a place out of the reach of children. As long as there is no key member, even if the infant operates the water server in various ways, the valve opening blocking member cannot be moved from the valve opening blocking position to the valve opening allowable position by operating the child lock release button, and the hot water Not dispensed. By storing the key member in a place that is out of the reach of the infant in this way, it is possible to extremely effectively prevent the infant from being burned.

A key passage that allows the key member to move in the direction of exiting the insertion port while the switch member is in the complete child lock position.
A guide wall that prevents the key member from moving in the direction of exiting the insertion port while the switch member is in the normal child lock position.
It is preferable to further provide.

In this way, when the switch member is normally in the child lock position, the movement of the key member in the direction of exiting from the insertion port is restricted by the guide wall. That is, the key member cannot be pulled out from the insertion port when the switch member is normally in the child lock position, and can be pulled out from the insertion port only when the switch member is in the complete child lock position. Therefore, when the key member is pulled out, the switch member always comes to the complete child lock position, and when the key member is pulled out, it is surely prevented from being in the normal child lock state, and high safety is ensured. be able to.

It is preferable to add the following configuration to the water server.
The switch member is a cylindrical member having the insertion port on the outer circumference.
The guide wall is a wall provided so as to face the insertion port portion on the outer periphery of the switch member in the radial direction while the switch member is in the normal child lock position.
The key member has a straight portion extending radially inward from the insertion port when inserted into the insertion port, and a bend extending axially along the guide wall from the radial outer end of the straight portion. Has a part.

In this way, even if the infant inserts a straight rod (a rod that is not a key member) into the insertion slot, the rod that does not have a bent part interferes with the guide wall, so the switch member is completely child-locked. Cannot be moved from position to normal child lock position. Therefore, it is possible to prevent the infant from releasing the complete child lock state by using a straight stick (such as a toothpick), and high safety can be ensured. On the other hand, since the key member has a bent portion, it does not interfere with the guide wall.

It is preferable that the switch member can be further moved to a child lock release holding position that holds the valve opening blocking member at the valve opening allowable position.

In this way, in a usage environment where infants do not enter (for example, a conference room in a company), by moving the switch member to the child lock release holding position, the operation of the child lock release button when pouring hot water is performed. Can be omitted, and the convenience of the water server becomes even higher.

At this time, the switch member is in a state where an operating force is applied to the child lock release button, and by operating the key member inserted into the insertion port, the child lock release holding position is changed from the normal child lock position. It is preferable that the child lock release button is prevented from moving from the normal child lock position to the child lock release holding position when no operating force is applied to the child lock release button.

In this way, the switch member cannot be moved from the normal child lock position to the child lock release holding position unless an operating force is applied to the child lock release button. Therefore, it is possible to prevent the infant from moving the switch member from the normal child lock position to the child lock release holding position, which is highly safe.

Since the keyed water server of the present invention is configured so that the key member can be carried independently of the housing, the key member can be stored out of the reach of children. As long as there is no key member, even if the infant operates the water server in various ways, the valve opening blocking member cannot be moved from the valve opening blocking position to the valve opening allowable position by operating the child lock release button, and the hot water Not dispensed. By storing the key member in a place that is out of the reach of the infant in this way, it is possible to extremely effectively prevent the infant from being burned.

FIG. 1 shows a keyed water server according to an embodiment of the present invention. This water server dispenses the housing 1 placed on the floor surface F, the cold water tank 2 housed inside the housing 1, and the low-temperature drinking water in the cold water tank 2 to the outside of the housing 1. Cold water injection path 3 to be used, a cold water injection valve 4 to open and close the cold water injection path 3, a hot water tank 5 housed inside the housing 1, and high-temperature drinking water in the hot water tank 5 outside the housing 1. It has a hot water pouring path 6 for pouring into and a hot water pouring valve 7 for opening and closing the hot water pouring path 6.

The housing 1 has a tubular portion 10 extending in the vertical direction, a top plate 11 provided so as to close the upper end of the tubular portion 10, and a bottom plate 12 provided so as to close the lower end of the tubular portion 10. The tubular portion 10 is composed of a pair of left and right side plates 13, a front plate 14 that connects the front edges of the side plates 13, and a rear surface plate 15 that connects the rear edges of the side plates 13.

A replaceable raw water container 16 is detachably set on the top plate 11 of the housing 1. The raw water container 16 is placed on the top plate 11 with the water outlet 17 facing downward. The capacity of the raw water container 16 is about 10 to 20 liters when the container is full. The raw water container 16 is formed with flexibility so as to shrink as the amount of residual water inside decreases. The top plate 11 is provided with a raw water introduction pipe 18 for introducing drinking water from the raw water container 16 into the cold water tank 2.

One end of the raw water introduction pipe 18 is detachably connected to the raw water container 16, and the other end of the raw water introduction pipe 18 is fixedly connected to the cold water tank 2. A float valve 19 that opens and closes according to the water level in the chilled water tank 2 is provided at the end of the raw water introduction pipe 18 on the chilled water tank 2 side. The float valve 19 is not required when the raw water container 16 is of a type formed with rigidity so as not to be deformed even if the amount of residual water inside is reduced. In this case, the water level in the chilled water tank 2 is the same as the end of the raw water introduction pipe 18 on the chilled water tank 2 side. A decorative cover 20 that covers the raw water container 16 is attached to the upper portion of the housing 1.

The cold water tank 2 accommodates air and drinking water in two upper and lower layers. The chilled water tank 2 is provided with a cooling device 21 for cooling the drinking water contained in the chilled water tank 2. Further, in the cold water tank 2, a baffle plate 22 for partitioning the inside of the cold water tank 2 up and down is provided. The cooling device 21 keeps the drinking water below the baffle plate 22 in the cold water tank 2 at a low temperature (about 5 ° C.). The capacity of drinking water in the cold water tank 2 is smaller than the capacity of the raw water container 16 and is about 2 to 4 liters.

The chilled water injection path 3 communicates between the chilled water tank 2 and the chilled water outlet 23 (see FIG. 2) that opens on the front side of the housing 1. A cold water injection valve 4 is provided at the end of the cold water injection path 3 on the side of the cold water outlet 23. When the cold water injection valve 4 is opened, the low-temperature drinking water in the cold water tank 2 passes through the cold water injection path 3 and is discharged from the cold water outlet 23.

The hot water tank 5 is arranged below the cold water tank 2. A heating device 24 for heating the drinking water contained in the hot water tank 5 is attached to the hot water tank 5. The heating device 24 keeps the drinking water in the hot water tank 5 at a high temperature (about 90 ° C.). The capacity of the hot water tank 5 is about 1 to 2 liters.

The hot water injection path 6 communicates between the hot water tank 5 and the hot water outlet 25 that opens on the front side of the housing 1. A hot water injection valve 7 is provided at the end of the hot water injection path 6 on the side of the hot water outlet 25. When the hot water pouring valve 7 is opened, the hot drinking water in the hot water tank 5 passes through the hot water pouring passage 6 and is poured out from the hot water outlet 25.

The cold water tank 2 and the hot water tank 5 communicate with each other via a tank connecting pipe 26. When drinking water is poured out from the hot water tank 5, the same amount of drinking water as the drinking water flows into the hot water tank 5 from the cold water tank 2 through the tank connecting pipe 26, and the hot water tank 5 is always kept full. It is designed to be used.

This water server is usually provided with a child lock function to prevent infants from inadvertently operating and pouring hot water. In the normal child lock function, the operation for opening the hot water injection valve 7 is a combination of two or more operations (specifically, the operation of the child lock release button 47 described later and the hot water injection operation lever 43). By combining this with the operation of (1), the hot water injection valve 7 is prevented from opening easily even if the infant operates it.

Further, this water server has a portable key member 30 in addition to the above-mentioned normal child lock function to ensure that hot water is prevented from being poured out even if the infant operates the water server in various ways. A complete child lock function using is provided. This complete child lock function allows the hot water injection valve 7 to be opened by an external operation (operation of the child lock release button 47 and the hot water injection operation lever 43) only when the key member 30 shown in FIG. 3 is present. This is a function that prevents the hot water injection valve 7 from being opened by an external operation without the key member 30.

As shown in FIG. 3, the key member 30 has a grip portion 31, a grip side straight portion 32, a bent portion 33, and a tip side straight portion 34 in this order from the grip portion 31 toward the tip end. The picking portion 31 is a portion to be picked by a finger when the user operates the key member 30. The picking side straight portion 32 and the tip side straight portion 34 are both formed so as to extend straight, and the end portion of the picking side straight portion 32 and the end portion of the tip side straight portion 34 are connected via a bent portion 33. ..

As shown in FIG. 4, the hot water injection valve 7 can be moved between a valve closing position (see FIG. 4) that closes the hot water injection path 6 and a valve opening position (see FIG. 10) that opens the hot water injection path 6. A valve body 40 provided in the valve body 40, a valve spring 41 for urging the valve body 40 from a valve opening position to a valve closing position, and a valve rod 42 fixed to the valve body 40 so as to move integrally with the valve body 40. It has a hot water pouring operation lever 43 operated by a user to pour hot water. The hot water pouring operation lever 43 is connected to the valve rod 42 via the connecting pin 44, and the valve body 40 can be moved from the valve closing position to the valve opening position by operating the hot water pouring operation lever 43. It has become.

Further, in the hot water injection valve 7, the valve opening blocking position (see FIG. 4) that prevents the valve body 40 from moving from the valve closing position to the valve opening position and the valve body 40 of the hot water injection valve 7 are in the valve closing position. The valve opening blocking member 45 provided so as to be movable between the valve opening permitting position (see FIG. 10) that allows the valve to move from the valve opening blocking position and the valve opening blocking member 45 are opened from the valve opening permitting position. The lock spring 46 urging the blocking position, the child lock release button 47 operated by the user to move the valve opening blocking member 45 from the valve opening blocking position to the valve opening allowable position, and the child lock release button 47 can be operated. It has a switch member 48 for switching between a normal state and an inoperable state.

The valve stem 42 is arranged so as to extend in the vertical direction, and is supported so as to be movable up and down. When the valve body 40 moves from the valve closing position to the valve opening position, the valve rod 42 moves upward, and when the valve body 40 moves from the valve opening position to the valve closing position, the valve rod 42 moves downward. A step portion 49 having a large diameter on the lower side is formed on the outer periphery of the valve stem 42. The valve opening blocking member 45 is formed with a through hole 50 in the vertical direction through which the valve rod 42 is inserted. When the valve opening blocking member 45 is in the valve opening blocking position (see FIG. 4), the edge of the through hole 50 of the valve opening blocking member 45 engages with the step portion 49 on the outer periphery of the valve rod 42 to engage the valve rod 42. When the valve opening blocking member 45 is in the valve opening allowable position (see FIG. 10) by blocking the upward movement, the through hole 50 of the valve opening blocking member 45 is allowed to pass through the step portion 49 on the outer circumference of the valve rod 42. The valve rod 42 is allowed to move upward.

As shown in FIG. 5, the child lock release button 47 includes a button body 53 slidably housed in a button housing hole 52 opened on the front side of the faucet case 51, and a button extending rearward from the button body 53. It has a plunger 54 integrally formed with the main body 53. The plunger 54 inserts an axial through hole 55 formed in the switch member 48 and protrudes rearward in the axial direction from the switch member 48. The rear end of the plunger 54 is in contact with the valve opening blocking member 45. When the child lock release button 47 is pressed and moved rearward in the axial direction, the valve opening blocking member 45 is pressed by the plunger 54 and moves rearward together with the child lock release button 47.

As shown in FIG. 6, the switch member 48 is a cylindrical member having an insertion port 60 into which the key member 30 is inserted on the outer periphery, and is rotatably supported by the holder member 61. The switch member 48 is normally movable in the circumferential direction between the child lock position (see FIG. 6), the complete child lock position (see FIG. 13), and the child lock release holding position (see FIG. 17). A protrusion 62 is provided on the outer circumference of the plunger 54 of the child lock release button 47, and an axial groove 63 is formed on the inner circumference of the through hole 55 of the switch member 48 to engage the protrusion 62 so as to be slidable in the axial direction. Has been done. By engaging the protrusion 62 with the groove 63, the child lock release button 47 rotates integrally with the switch member 48.

The holder member 61 is provided with a guide wall 64 that prevents the key member 30 from moving in the direction of exiting the insertion port 60 while the switch member 48 is normally in the child lock position. The guide wall 64 is a wall provided so as to face the portion of the outer peripheral insertion port 60 of the switch member 48 in the radial direction in a state where the switch member 48 is normally in the child lock position. A passage 65 extending in an arc shape is formed between the guide wall 64 and the outer periphery of the switch member 48, and the bent portion 33 of the key member 30 can move in the circumferential direction through the passage 65.

Further, as shown in FIG. 13, a key that allows the key member 30 to move in the direction of exiting the insertion port 60 while the switch member 48 is in the complete child lock position on the faucet case 51 and the holder member 61. A passage 66 is formed. The key passage 66 extends radially outward from the circumferential end of the arcuate passage 65.

As shown in FIG. 5, the straight portion 34 on the tip end side of the key member 30 extends inward in the radial direction from the insertion port 60 in a state where the key member 30 is inserted into the insertion port 60. The bent portion 33 extends axially along the guide wall 64 from the radial outer end of the tip-side straight portion 34. Further, the faucet case 51 and the holder member 61 are formed with slits 67 for accommodating the picking side straight portion 32 so as to be movable in the circumferential direction between the opposing surfaces in the axial direction.

As shown in FIG. 7, a plurality of radial protrusions 68 are provided on the outer periphery of the button body 53 of the child lock release button 47 at intervals in the circumferential direction. The holder member 61 is provided with a plurality of stopper protrusions 69 corresponding to the plurality of radial protrusions 68 of the button body 53 at intervals in the circumferential direction. When the switch member 48 is in the normal child lock position (see FIG. 6), the stopper protrusion 69 has a positional relationship deviated from the radial protrusion 68 of the button body 53 when viewed in the axial direction, as shown in FIG. The child lock release button 47 is allowed to move backward in the axial direction, but when the switch member 48 is in the complete child lock position (see FIG. 13), the button body 53 is viewed in the axial direction as shown in FIG. The radial protrusion 68 of the button body 53 is received from the rear side in the axial direction, so that the child lock release button 47 is prevented from moving backward in the axial direction.

As shown in FIG. 5, a plurality of columnar protrusions 70 are formed on the surface of the switch member 48 that faces the valve opening blocking member 45 in the axial direction at intervals in the circumferential direction. Further, a plurality of columnar protrusions 71 are also formed on the surface of the valve opening blocking member 45 facing the switch member 48 in the axial direction at intervals in the circumferential direction.

As shown in FIG. 8, the side surface of the columnar protrusion 70 of the switch member 48 faces the side surface of the columnar protrusion 71 of the valve opening blocking member 45 in the circumferential direction, and the side surface of the columnar protrusion 70 is on the side surface of the columnar protrusion 71. By contacting the switch member 48, the movement of the switch member 48 from the normal child lock position to the child lock release holding position is restricted. The valve opening blocking member 45 is supported on the inner surface of the support hole 72 (see FIG. 5) formed in the holder member 61 so as to be slidable in the axial direction and prevented from rotating.

An example of using this keyed water server will be described.

<Complete child lock state>
As shown in FIGS. 11, 12, and 13, in a state where the key member 30 is operated and the switch member 48 is moved to the complete child lock position, even if the child lock release button 47 is pressed, the child lock release button is pressed. 47 cannot be pushed and moved, and the child lock cannot be released.

That is, when the switch member 48 is in the complete child lock position, as shown in FIG. 14, the radial protrusion 68 of the button body 53 of the child lock release button 47 is arranged to overlap the stopper protrusion 69, so that the child lock release button Even if the 47 was pressed, the child lock release button 47 could not be moved, and as shown in FIG. 12, the valve opening blocking member 45 was prevented from moving from the valve opening blocking position to the valve opening allowable position. It becomes a state. That is, hot water cannot be dispensed by operating the child lock release button 47 and the hot water pouring operation lever 43.

At this time, as shown in FIG. 13, since the position of the insertion port 60 and the position of the key passage 66 are aligned in a straight line, the key member 30 can be pulled out from the insertion port 60. By storing the pulled out key member 30 in a place out of the reach of the infant, it is possible to extremely effectively prevent the infant from being burned. That is, unless the key member 30 is present, even if the infant operates the water server in various ways, the valve opening blocking member 45 cannot be moved from the valve opening blocking position to the valve opening allowable position by operating the child lock release button 47. , It is possible to surely prevent the pouring of hot water by infants.

Here, even if the infant inserts a straight rod (a rod other than the key member 30) into the insertion port 60 in a state where the key member 30 shown in FIG. 13 is pulled out from the insertion port 60, the bent portion 33 is inserted. Since the stickless rod interferes with the guide wall 64, the switch member 48 cannot be moved from the complete child lock position to the normal child lock position. Therefore, it is possible to prevent the infant from releasing the completely child-locked state by using a straight stick (such as a toothpick), and it is possible to ensure high safety. On the other hand, since the key member 30 has the bent portion 33, it does not interfere with the guide wall 64 even if it is moved in the circumferential direction while being inserted into the insertion port 60.

<Normal child lock state>
By operating the key member 30 inserted into the insertion port 60, the switch member 48 is moved from the complete child lock position (see FIG. 13) to the normal child lock position (see FIG. 6). In this state, the child lock release button 47 can be pushed and moved.

That is, as shown in FIG. 6, when the switch member 48 is in the normal child lock position, as shown in FIG. 7, the radial protrusion 68 of the button body 53 of the child lock release button 47 is from the position of the stopper protrusion 69. Since the child lock release button 47 is released from the movement restriction by the stopper protrusion 69 in the displaced state, the valve opening prevention member 45 is moved from the valve opening prevention position to the valve opening allowable position by operating the child lock release button 47. It will be in an allowed state. In this state, hot water can be dispensed by operating the hot water pouring operation lever 43 while pressing the child lock release button 47.

<Child lock release holding state>
In a usage environment where infants do not enter (for example, a conference room in a company), the child lock release button 47 is pushed in as shown in FIG. 16, and the key member 30 is operated in that state as shown in FIG. The switch member 48 is moved from the normal child lock position (see FIG. 6) to the child lock release holding position (FIG. 17). As a result, as shown in FIG. 18, the tip surface of the columnar protrusion 70 of the switch member 48 and the tip surface of the columnar protrusion 71 of the valve opening prevention member 45 are in a state of being butted in the axial direction, and are shown in FIG. As described above, the valve opening blocking member 45 is held in the valve opening allowable position. In this state, it is possible to omit the operation of the child lock release button 47 when pouring hot water, and the hot water can be dispensed simply by operating the hot water pouring operation lever 43 without operating the child lock release button 47. Can be dispensed.

Here, when the switch member 48 is moved from the normal child lock position (see FIG. 6) to the child lock release holding position (FIG. 17), unless an operating force is applied to the child lock release button 47, FIG. As shown, the switch member 48 cannot be moved from the normal child lock position to the child lock release holding position because the columnar protrusions 70 and the columnar protrusions 71 interfere with each other in the circumferential direction. Therefore, it is possible to prevent the infant from moving the switch member 48 from the normal child lock position to the child lock release holding position, which is highly safe.

Since the key member 30 can be carried independently from the housing 1, the keyed water server can be stored in a place out of the reach of children. Then, unless the key member 30 is present, even if the infant operates the water server in various ways, the valve opening blocking member 45 cannot be moved from the valve opening blocking position to the valve opening allowable position by operating the child lock release button 47. , Hot water is not poured out. In this way, by storing the key member 30 in a place out of the reach of the infant, it is possible to extremely effectively prevent the infant from being burned.

Further, in this water server with a key, as shown in FIG. 6, when the switch member 48 is in the normal child lock position, the movement of the key member 30 in the direction of exiting from the insertion port 60 is restricted by the guide wall 64. To. That is, the key member 30 cannot be pulled out from the insertion port 60 when the switch member 48 is normally in the child lock position, and as shown in FIG. 13, only when the switch member 48 is in the complete child lock position. , Can be pulled out from the insertion port 60. Therefore, when the key member 30 is pulled out, the switch member 48 always comes to the complete child lock position, and when the key member 30 is pulled out, it is surely prevented from being in the normal child lock state, and high safety is achieved. Can be secured.

The above-mentioned normal child lock function and complete child lock function can be provided not only in the hot water injection valve 7 but also in the cold water injection valve 4. Here, when the same configuration as that of the hot water injection valve 7 is adopted for the cold water injection valve 4, there is a risk that the infant uses the key member 30c of the cold water injection valve 4 as the key member 30 of the hot water injection valve 7. There is. In order to eliminate such a risk, it is preferable that the key member 30c of the cold water injection valve 4 is configured so that it cannot be used for the hot water injection valve 7. As the key member 30c having such a configuration, for example, as shown in FIG. 19, a key member 30c having a bent portion 33c having a diameter set larger than that of the bent portion 33 of the key member 30 of the hot water discharge valve 7 is adopted. be able to. At this time, the inner width in the radial direction of the passage 65c through which the bent portion 33c of the key member 30c of the cold water injection valve 4 passes is within the radial direction of the passage 65 through which the bent portion 33 of the key member 30 of the hot water injection valve 7 passes. Set larger than the width.
