Description

  The present invention relates to a water server with a key that can prevent a burn accident of an infant extremely effectively.

  Conventionally, water servers have been used mainly in offices and hospitals, but in recent years, water servers are becoming widespread in ordinary households due to increasing interest in water safety and health. A water server usually has a housing, a cold water tank accommodated in the housing, a cold water pouring path for pouring low-temperature drinking water in the cold water tank to the outside of the housing, and the cold water pouring path. A chilled water pouring valve that opens and closes the chilled water, and a chilled water pouring operation section that is operated by a user to open the chilled water pouring valve. Can be done.

  The water server also includes a hot water tank housed in 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 warming water pouring operation part operated by a user to open the valve and the warm water pouring valve so that hot water can be used by operating this warm water pouring operation part There are many things.

  By the way, in the type of water server that can use hot water, a child lock function is provided 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 hot water is not easily poured even if operated by an infant. (For example, patent document 1).

  However, even when the child lock function is provided, the operation to pour out hot water happens to happen accidentally while the infant performs various operations, or the operation to be performed when an adult pours out hot water. There was a problem that the risk of scalding hot water from being poured out by the infant could not be completely eliminated because there was a possibility that the infant would look and imitate it.

  In other words, the more complicated the operation for pouring hot water is, the more the child lock function can be strengthened, and it becomes possible to prevent infant burn accidents more effectively. The operation when an adult is pouring hot water becomes complicated and the convenience of the water server is sacrificed. For this reason, there is a limit to strengthening the child lock function, and it has been difficult to completely eliminate the risk of the infant pouring hot water with the child lock function alone.

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

In order to solve the above problems, the present invention provides a water server having the following configuration.
A housing,
A hot water tank disposed inside the housing;
A hot water pouring path for pouring hot drinking water in the hot water tank to the outside of the housing;
A hot water pouring valve for opening and closing the hot water pouring path;
A hot water dispensing operation unit operated by a user to open the hot water dispensing valve;
A key member configured to be carried independently from the housing;
Only when the key member is present, the hot water pouring valve is opened by the operation of the hot water pouring operation unit, and when there is no key member, the hot water pouring operation unit is operated even when the hot water pouring operation unit is operated. Child proof means for preventing the valve from opening; and
With keyed water server.

  In this way, the key member can be carried independently from the housing, and therefore the key member can be stored in a place that is out of the reach of infants. And if there is no key member, even if it operates a warm water extraction operation part, it will be in the state where a warm water extraction valve does not open. That is, even if the infant operates the water server in various ways, the hot water is not poured out unless there is a key member. Thus, by storing the key member in a place out of the reach of the infant, it is possible to extremely effectively prevent an infant burn accident.

In the case where a manual open / close valve having a valve body that moves from a valve closing position to a valve opening position by a user's operating force is adopted as the hot water pouring valve, the following configuration can be added.
The warm water pouring operation section is
An open valve blocking position that prevents the valve body of the hot water discharge valve from moving from the closed position to the open position, and the valve body of the hot water discharge valve is allowed to move from the closed position to the open position. A child lock operation member that is operated by a user to move a valve opening prevention member that is movable between the valve opening prevention position and the valve opening prevention position from the valve opening prevention position;
A hot water dispensing operation lever operated by a user to move the valve body of the hot water dispensing valve from the valve closing position to the valve opening position in a state where the child lock operation member is operated;
The child proof means includes:
An insertion port for inserting and removing the key member;
An operating force for a user to operate the child lock operating member to move the valve opening blocking member from the valve opening blocking position to the valve opening allowable position is transmitted from the child lock operating member to the valve opening blocking member. An operating force transmission path,
The operation force transmission path is configured to block transmission of the operation force from the child lock operation member to the valve opening prevention member in a state where the key member is extracted from the insertion port.

  In this way, when there is no key member, the transmission of the operation force from the child lock operation member to the valve opening prevention member is cut off, so even if the child lock operation member is operated, the valve opening prevention member Does not move from the valve opening prevention position to the valve opening allowable position. Therefore, by storing the key member in a place out of the reach of the infant, the child lock can be prevented from being released by the infant's operation, and the hot water can be reliably prevented from being poured out by the infant. In addition, even when there is a key member, it is possible to prevent the infant from pouring hot water by the child lock function.

Further, in the case where a manual opening / closing valve having a valve body that moves from the valve closing position to the valve opening position by a user's operating force is adopted as the hot water pouring valve, the following configuration can be added.
The warm water pouring operation section is
A hot water dispensing operation lever operated by a user to move the valve body of the hot water dispensing valve from the closed position to the open position;
The child proof means includes:
An insertion port for inserting and removing the key member;
In order to move the valve body of the hot water pouring valve from the closed position to the open position, a user operates the hot water pouring operation lever from the hot water pouring operation lever to the valve of the hot water pouring valve. An operating force transmission path that transmits to the body,
The operation force transmission path is configured to block transmission of operation force from the hot water extraction operation lever to the valve body of the hot water extraction valve in a state where the key member is extracted from the insertion port. Has been.

  In this way, when there is no key member, the transmission of the operating force from the hot water pouring operation lever to the valve body of the hot water pouring valve is cut off, so even if the hot water pouring operation lever is operated The valve element of the hot water discharge valve does not move from the closed position to the open position. Therefore, by storing the key member in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water.

Moreover, when employ | adopting the electromagnetic opening-and-closing valve opened by electricity supply as the said hot water extraction valve, the following structures can be added.
The warm water pouring operation section is
A hot water pouring operation switch operated by a user to open the hot water pouring valve;
The child proof means includes:
A key sensor for detecting the presence or absence of the key member;
An electronic control unit that controls the hot water dispensing valve based on signals input from the key sensor and the hot water dispensing operation switch;
When the key sensor does not detect the key member, the electronic control device deenergizes the hot water extraction valve even when the hot water extraction operation switch is operated, and the key sensor detects the key member. When the hot water dispensing operation switch is operated, the hot water dispensing valve is energized.

  If it does in this way, when there is no key member, even if it operates a warm water extraction operation switch, it will be in the state where electricity supply to a warm water extraction valve is not performed. Therefore, by storing the key member in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water.

  The water server with a key according to the present invention is configured so that the key member can be carried independently from the casing, so that the key member can be stored in a place out of the reach of infants. And if there is no key member, even if it operates a warm water extraction operation part, it will be in the state where a warm water extraction valve does not open. That is, even if the infant operates the water server in various ways, the hot water is not poured out unless there is a key member. Thus, by storing the key member in a place out of the reach of the infant, it is possible to prevent an infant's burn accident very effectively.

  The housing 1 has a cylindrical portion 10 extending in the vertical direction, a top plate 11 provided so as to close the upper end of the cylindrical portion 10, and a bottom plate 12 provided so as to close the lower end of the cylindrical portion 10. The cylindrical 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 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 water is full. The raw water container 16 is formed with flexibility so as to contract 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 to 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 cold water tank 2 is provided at the end of the raw water introduction pipe 18 on the cold water tank 2 side. 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, the float valve 19 is unnecessary. In this case, the water level in the cold water tank 2 becomes the same height as the end of the raw water introduction pipe 18 on the cold water tank 2 side. A decorative cover 20 that covers the raw water container 16 is attached to the top of the housing 1.

  The cold water tank 2 contains air and drinking water in upper and lower layers. The cold water tank 2 is provided with a cooling device 21 for cooling the drinking water stored in the cold water tank 2. In the cold water tank 2, a baffle plate 22 that partitions 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 cold water pouring channel 3 communicates between the cold water tank 2 and a cold water outlet 23 (see FIG. 2) that opens to the front side of the housing 1. A cold water extraction valve 4 is provided at the end of the cold water extraction path 3 on the cold water outlet 23 side. When the cold water pouring valve 4 is opened, the low-temperature drinking water in the cold water tank 2 passes through the cold water pouring channel 3 and is poured out from the cold water outlet 23.

  The hot water tank 6 is disposed below the cold water tank 2. A heating device 24 that heats the drinking water stored in the hot water tank 6 is attached to the hot water tank 6.

  The cold water tank 2 and the hot water tank 6 communicate with each other via a tank connection pipe 26. When drinking water is poured out from the hot water tank 6, the same amount of drinking water as that drinking water flows into the hot water tank 6 from the cold water tank 2 through the tank connection pipe 26, and the hot water tank 6 is always kept in a full state. It is supposed to be.

  This water server is provided with a child lock function in order to prevent an infant from inadvertently operating the water server to dispense hot water. The child lock function is a combination of two or more operations for opening the hot water pouring valve 8 (in this embodiment, an operation of a child lock operating member 30 described later and an operation of the hot water pouring operation lever 31). In combination with the operation), the hot water discharge valve 8 is not easily opened even when an infant operates.

  Furthermore, this water server uses a portable key member in addition to the child lock function to ensure that hot water can be prevented from being poured out even if an infant operates the water server in various ways. A child proof function is provided. In this child proof function, only when the key member 32 shown in FIG. 3 is provided, the hot water pouring valve 8 is opened according to the operation of the hot water pouring operation portion 9 (the child lock operation member 30 and the hot water pouring operation lever 31). The function is to prevent the warm water dispensing valve 8 from opening even when the warm water dispensing operation unit 9 is operated in a state where the key member 32 is not provided. A specific example will be described below.

  As shown in FIGS. 4 to 6, the hot water pouring valve 8 is between a valve closing position (see FIG. 4) for closing the hot water pouring path 7 and an opening position (see FIG. 6) for opening the hot water pouring path 7. A valve body 33 provided so as to be movable, a valve spring 34 for urging the valve body 33 from the valve opening position to the valve closing position, and a valve rod fixed to the valve body 33 so as to move integrally with the valve body 33 35 and a hot water pouring operation lever 31 operated by the user for pouring hot water. The hot water pouring operation lever 31 is connected to the valve rod 35 via the connecting pin 36, and the valve element 33 can be moved from the valve closing position to the valve opening position by operating the hot water pouring operation lever 31. It has become. Thus, the hot water pouring valve 8 is a manual on-off valve having the valve element 33 that moves from the valve closing position to the valve opening position by the user's operating force.

  Further, the hot water dispensing valve 8 includes a valve opening preventing position (see FIG. 4) that prevents the valve element 33 from moving from the valve closing position to the valve opening position, and the valve element 33 of the hot water dispensing valve 8 is in the valve closing position. A valve opening blocking member 37 movably provided between a valve opening permission position (see FIG. 6) that permits movement from the valve opening position to the valve opening position, and opening the valve opening blocking member 37 from the valve opening permission position. It has a lock spring 38 that biases to the blocking position, and a child lock operating member 30 that is operated by the user to move the valve opening blocking member 37 from the valve opening blocking position to the valve opening permission position.

  The valve stem 35 is disposed so as to extend in the vertical direction, and is supported so as to be movable up and down. When the valve element 33 moves from the valve closing position to the valve opening position, the valve rod 35 moves upward. When the valve element 33 moves from the valve opening position to the valve closing position, the valve rod 35 moves downward. On the outer periphery of the valve stem 35, a step portion 39 having a large diameter on the lower side is formed. The valve opening blocking member 37 is formed with a vertical through hole 40 through which the valve rod 35 is inserted. When the valve-opening blocking member 37 is in the valve-opening blocking position (see FIG. 4), the edge of the through hole 40 of the valve-opening blocking member 37 engages with the step 39 on the outer periphery of the valve rod 35 and When the valve-opening blocking member 37 is in the valve-opening allowed position (see FIG. 6), the through-hole 40 of the valve-opening blocking member 37 allows the step 39 on the outer periphery of the valve rod 35 to pass. Thus, upward movement of the valve stem 35 is allowed.

  Further, the water server includes a key member 32 configured to be carried independently from the housing 1 as shown in FIG. 3, and hot water only when the key member 32 is present as shown in FIG. The hot water pouring valve 8 is opened by the operation of the pouring operation section 9, and as shown in FIG. 7, even if the hot water pouring operation section 9 is operated without the key member 32, the hot water pouring valve 8 is operated. Has child proof means 41 for preventing the valve from opening.

  As shown in FIG. 6, the child proof means 41 includes an insertion port 42 through which the key member 32 is inserted and removed, and an operation force for the user to operate the child lock operation member 30 from the child lock operation member 30 to the valve opening prevention member 37. And an operating force transmission path 43 for transmission. The insertion port 42 is formed in the front plate 14 of the housing 1. When the key member 32 is inserted into the insertion port 42 from the outside of the housing 1, the tip of the key member 32 is guided by a guide portion (not shown) and introduced between the child lock operation member 30 and the valve opening prevention member 37. It is like that.

  The operation force transmission path 43 includes a child lock operation member 30, a key member 32 inserted into the insertion port 42, and a valve opening prevention member 37. The child lock operation member 30 is a push button supported so as to be slidable between a push-in position (see FIG. 7) and a return position (see FIG. 4). As shown in FIG. 4, a return spring 44 that urges the child lock operation member 30 from the push-in position to the return position is incorporated in the child lock operation member 30.

  As shown in FIG. 4, a space 45 is provided between the child lock operating member 30 and the valve-opening blocking member 37 in a state where the key member 32 is not present. The space 45 is set to be larger than the movable stroke of the child lock operating member 30 minus the moving stroke when the valve opening blocking member 37 moves from the valve opening blocking position to the valve opening allowable position. As shown in FIG. 5, the key member 32 is a plate-like member having a thickness corresponding to the space 45 between the child lock operating member 30 and the valve opening prevention member 37. The key member 32 is a stick-shaped plate member in the figure, but may be a card-shaped plate member.

  As shown in FIGS. 5 and 6, in the state where the key member 32 is inserted into the insertion port 42, the operation force that pushes the child lock operation member 30 is opened from the child lock operation member 30 via the key member 32. On the other hand, as shown in FIG. 7, in the state where the key member 32 is pulled out from the insertion port 42 as shown in FIG. 7, even if the child lock operating member 30 is pushed and moved, the child lock operating member 30 and the valve opening blocking are prevented. In the space 45 between the members 37, transmission of the operating force is cut off.

  That is, as shown in FIG. 5, the key member 32 is inserted into the insertion port 42, and the key member 32 is inserted into the space 45 between the child lock operating member 30 and the valve opening prevention member 37. When the user pushes and moves the child lock operating member 30 in this state, the operating force is transmitted in sequence through the child lock operating member 30, the key member 32, and the valve opening preventing member 37, and as shown in FIG. The blocking member 37 moves from the valve opening blocking position to the valve opening allowable position. That is, in a state where the key member 32 is inserted into the insertion port 42, the valve-opening blocking member 37 can be moved from the valve-opening blocking position to the valve-opening allowable position by operating the child lock operating member 30. By operating the hot water pouring operation lever 31, the hot water pouring valve 8 is opened.

  On the other hand, as shown in FIG. 4, when the key member 32 is extracted from the insertion port 42, a space 45 is formed between the child lock operating member 30 and the valve opening prevention member 37. Even if the user pushes and moves the child lock operating member 30 in this state, the operating force is not transmitted from the child lock operating member 30 to the valve opening blocking member 37, and the valve opening blocking member 37 is opened as shown in FIG. Does not move from the valve blocking position. That is, in the state where the key member 32 is pulled out from the insertion port 42, even if the child lock operation member 30 is operated, the valve opening prevention member 37 does not move, and even if the hot water dispensing operation lever 31 is operated in this state. The hot water discharge valve 8 does not open.

  In the water server with a lock according to the first embodiment, when the key member 32 is not provided, the transmission of the operation force from the child lock operation member 30 to the valve opening prevention member 37 is cut off. Even if 30 is operated, the valve-opening blocking member 37 does not move from the valve-opening blocking position. That is, even if the infant operates the water server in various ways, the child lock is not released unless the key member 32 is provided, and the hot water is not poured out. Therefore, by storing the key member 32 in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water, and to prevent the infant from being burned extremely effectively. . Even when the key member 32 is provided, it is possible to prevent the infant from pouring hot water by the child lock function.

  FIG. 8 shows a keyed water server according to the second embodiment of the present invention. The lockable water server of the first embodiment has the child proof means 41 incorporated in advance, whereas the lockable water server of the second embodiment has the child proof means 41 retrofitted to an existing water server. It is different in that it is a thing. Hereinafter, parts corresponding to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  A cover panel 51 facing the outside of the front plate 14 provided with a child lock button 50 is attached to the housing 1 in order to add a child proof means 41 to an existing water server. The cover panel 51 is fixed to the housing 1 in such a manner that it cannot be removed by an infant.

  As shown in FIGS. 9 to 11, the cover panel 51 has an insertion port 42 for inserting and removing the key member 32, and a child lock operation member 30 for operating the valve opening prevention member 37 via the child lock button 50. Is provided.

  As shown in FIG. 10, the child proof means 41 has an insertion port 42 and an operation force transmission path for transmitting an operation force for the user to operate the child lock operation member 30 from the child lock operation member 30 to the valve opening prevention member 37. 43. The insertion port 42 is formed in the cover panel 51. When the key member 32 is inserted into the insertion port 42 from the outside of the cover panel 51, the tip of the key member 32 is guided by a guide portion (not shown) so as to be introduced between the child lock operation member 30 and the child lock button 50. It has become.

  The operating force transmission path 43 includes a child lock operation member 30, a key member 32 inserted into the insertion port 42, a child lock button 50, and a valve opening prevention member 37. The child lock operating member 30 is a push button that is slidably supported between a push-in position (see FIG. 12) and a return position (see FIG. 9). Inside the child lock operation member 30, a return spring 44 (see FIG. 9) for urging the child lock operation member 30 from the pushed-in position to the return position is incorporated.

  As shown in FIG. 9, there is a space 45 between the child lock operating member 30 and the child lock button 50 in the state where the key member 32 is not present. The space 45 is set to be larger than the movable stroke of the child lock operating member 30 minus the moving stroke when the valve opening blocking member 37 moves from the valve opening blocking position to the valve opening allowable position. As shown in FIG. 10, the key member 32 is a plate-like member having a thickness corresponding to the space 45 between the child lock operating member 30 and the child lock button 50.

  As shown in FIGS. 10 and 11, in the state where the key member 32 is inserted into the insertion port 42, the operation force that pushes the child lock operation member 30 is changed from the child lock operation member 30 to the key member 32 and the child lock button 50. On the other hand, as shown in FIG. 12, in the state where the key member 32 is pulled out from the insertion port 42 as shown in FIG. 12, even if the child lock operating member 30 is pushed and moved, the child lock operation is performed. In the space 45 between the member 30 and the child lock button 50, the transmission of the operating force is cut off.

  That is, as shown in FIG. 10, the key member 32 is inserted into the insertion port 42, and the key member 32 is inserted into the space 45 between the child lock operation member 30 and the child lock button 50. When the user pushes and moves the child lock operating member 30 in this state, the operating force is transmitted in sequence to the child lock operating member 30, the key member 32, the child lock button 50, and the valve-opening blocking member 37, as shown in FIG. As described above, the valve opening blocking member 37 moves from the valve opening blocking position to the valve opening allowable position. That is, in a state where the key member 32 is inserted into the insertion port 42, the valve-opening blocking member 37 can be moved from the valve-opening blocking position to the valve-opening allowable position by operating the child lock operating member 30. By operating the hot water pouring operation lever 31, the hot water pouring valve 8 is opened.

  On the other hand, as shown in FIG. 9, when the key member 32 is extracted from the insertion port 42, a space 45 is formed between the child lock operation member 30 and the child lock button 50. Even if the user pushes and moves the child lock operating member 30 in this state, the operating force is not transmitted from the child lock operating member 30 to the valve opening blocking member 37, and the valve opening blocking member 37 is opened as shown in FIG.

That is, in the state where the key member 32 is pulled out from the insertion port 42, even if the child lock operation member 30 is operated, the valve opening prevention member 37 does not move, and even if the hot water dispensing operation lever 31 is operated in this state. The hot water discharge valve 8 does not open.

  Similarly to the first embodiment, the water server with a lock according to the second embodiment is in a state where the transmission of the operation force from the child lock operation member 30 to the valve opening prevention member 37 is cut off when the key member 32 is not provided. Therefore, even if the child lock operating member 30 is operated, the valve opening blocking member 37 does not move from the valve opening blocking position. That is, even if the infant operates the water server in various ways, the child lock is not released unless the key member 32 is provided, and the hot water is not poured out. Therefore, by storing the key member 32 in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water, and to prevent the infant from being burned extremely effectively. . Even when the key member 32 is provided, it is possible to prevent the infant from pouring hot water by the child lock function.

  In the said 1st Embodiment and 2nd Embodiment, in the state which inserted the key member 32 in the insertion port 42, the operation force in which a user operates the child lock operation member 30 is the valve opening prevention member from the child lock operation member 30. On the other hand, in a state where the key member 32 is pulled out from the insertion port 42, the child proof means 41 configured so that the transmission of the operation force from the child lock operation member 30 to the valve opening prevention member 37 is cut off. Although the example which employ | adopted was demonstrated, it is also possible to employ | adopt the child proof means 41 which replaced the child lock operation member 30 with the warm water extraction operation lever 31. FIG.

  That is, in a state where the key member 32 is inserted into the insertion port 42, an operating force for the user to operate the hot water pouring operation lever 31 is transmitted from the hot water pouring operation lever 31 to the valve body 33, while the key member 32 is operated. The child proof means 41 may be configured so that the transmission of the operation force from the hot water pouring operation lever 31 to the valve body 33 is cut off in the state where the water is extracted from the insertion port 42.

  In this way, when there is no key member 32, the transmission of the operating force from the hot water pouring operation lever 31 to the valve body 33 is interrupted, so even if the hot water pouring operation lever 31 is operated, The valve element 33 of the hot water pouring valve 8 does not move from the valve closing position to the valve opening position. Therefore, by storing the key member 32 in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water.

  FIG. 13 shows a keyed water server according to the third embodiment of the present invention. In the first embodiment and the second embodiment, a manual on-off valve having a valve body 33 that moves from the valve-closing position to the valve-opening position by the user's operating force is adopted as the hot water discharge valve 8, whereas In the third embodiment, an electromagnetic on-off valve that opens when energized is used for the hot water pouring valve 8. Hereinafter, parts corresponding to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The hot water pouring valve 8 is an electromagnetic on-off valve that opens when the electromagnetic coil 60 is energized, and closes when the electromagnetic coil 60 is de-energized. A hot water pouring operation switch 61 is provided in the housing 1 as the hot water pouring operation unit 9 operated by the user to open the hot water pouring valve 8.

  In addition, the water server includes a key member 32 configured to be carried independently from the housing 1, and the hot water discharge valve 8 is operated by operating the hot water discharge operation switch 61 only when the key member 32 is provided. A child proof means 41 is provided so that the warm water dispensing valve 8 is not opened even if the warm water dispensing operation switch 61 is operated in a state where the key member 32 is not provided.

  The child proof means 41 includes a key sensor 62 that detects the presence or absence of the key member 32, and an electronic control device 63 that controls the hot water dispensing valve 8 based on signals input from the key sensor 62 and the hot water dispensing operation switch 61. Have The electronic control device 63 is electrically connected to the key sensor 62, the hot water extraction operation switch 61, and the hot water extraction valve 8. The key member 32 is, for example, a card key in which a non-contact IC chip is embedded. In this case, the key sensor 62 is an IC card reader.

  When the key sensor 62 does not detect the key member 32, the electronic control device 63 deenergizes the hot water extraction valve 8 even if the hot water extraction operation switch 61 is operated, while the key sensor 62 causes the key member 32 to be disconnected. When detected, the hot water dispensing valve 8 is energized in accordance with the operation of the hot water dispensing operation switch 61.

  In the water server with a lock according to the third embodiment, when the key member 32 is not provided, even if the warm water dispensing operation switch 61 is operated, the warm water dispensing valve 8 is not energized. That is, even if the infant operates the water server in various ways, the hot water is not poured out unless the key member 32 is provided. Therefore, by storing the key member 32 in a place out of the reach of the infant, it is possible to reliably prevent the infant from pouring hot water, and to prevent the infant from being burned extremely effectively. .

  In addition, even when an electromagnetic on-off valve that is opened by energization is employed in the hot water discharge valve 8 as in the third embodiment, the insertion and removal of the key member 32 as in the first and second embodiments. In the state where the port 42 is provided and the key member 32 is inserted into the insertion port 42, the user's operation force is transmitted to the hot water dispensing operation switch 61, while in the state where the key member 32 is extracted from the insertion port 42. The child proof means 41 can be configured so that the user's operating force is blocked from being transmitted to the hot water dispensing operation switch 61.

  The child proof means 41 of each of the above embodiments may be provided not only on the hot water side but also on the cold water side. That is, only when the key member 32 is present, the chilled water dispensing valve 4 is opened by operating the chilled water dispensing operation unit 5, and even when the chilled water dispensing operation unit 5 is operated without the key member 32, A child proof means 41 having the same structure as the hot water side may be additionally provided on the cold water side so that the outlet valve 4 does not open. In this way, it is possible to reliably prevent the cold water from being poured out by the infant, and it is possible to extremely effectively prevent a flooding accident under the floor due to the mischief of the infant.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
