Description

Keyed Water Server

The present invention relates to a water server with a key which makes it possible to very effectively prevent a burn accident of an infant.

Conventionally, water servers have been mainly used in offices, hospitals, and the like. However, in recent years, as interest in water safety and health has increased, water servers have been popularized in general households as well. A water server generally includes a housing, a cold water tank accommodated in the housing, a cold water pouring path for pouring low-temperature beverages in the cold water tank to the outside of the housing, and opening and closing the cold water pouring path It has a cold water pouring valve, and the cold water pouring operation part operated by a user in order to open the cold water pouring valve, It is comprised so that cold water can be used by operating this cold water pouring operation part.

In addition, the water server includes a hot water tank accommodated in the housing, a hot water dispensing path for dispensing hot beverages in the hot water tank to the outside of the housing, a hot water dispensing valve for opening and closing the hot water dispensing path, and the hot water dispensing In many cases, a hot water pouring operation unit operated by a user to open a valve is further provided, and hot water can be used by operating the hot water pouring operation unit.

By the way, in a water server of the type that can use hot water, a child lock function is provided in order to prevent an infant from inadvertently operating the water server to dispense hot water. In the child lock function, the operation for pouring out hot water from the water server is a combination of two or more operations, so that hot water is not easily dispensed even if an infant operates (for example, Patent Document 1 below).

However, even when the child lock function is provided, there is a possibility that the operation of dispensing hot water may happen occasionally while the infant is operating in various ways, or that the operation performed when an adult dispenses hot water may be seen and imitated by the infant. However, there was a problem that the risk of getting burned by pouring hot water could not be completely eliminated.

That is, the more complicated the operation for dispensing hot water, the more effective the child lock function can be and the more effective prevention of burn accidents for infants. It becomes one thing, and the convenience of the water server is sacrificed. Therefore, there is a limit in strengthening the child lock function, and it is difficult to completely eliminate the risk of the infant pouring out hot water only by the child lock function.

Although the example which employ|adopted the child proof means 41 comprised so that it may be possible is demonstrated, it is also possible to employ|adopt the child proof means 41 which replaced the child lock operation member 30 with the hot water pouring operation lever 31.

That is, in the state in which the key member 32 is inserted into the insertion port 42, the operating force for the user to operate the hot water dispensing operation lever 31 is transmitted from the hot water dispensing operation lever 31 to the valve body 33, On the other hand, in the state in which the key member 32 is pulled out from the insertion port 42, you may comprise the child proof means 41 so that transmission of the operating force from the hot water pouring operation lever 31 to the valve body 33 may be interrupted|blocked.

In this way, when the key member 32 is not present, the transmission of the operating force from the hot water pouring operation lever 31 to the valve body 33 is blocked. The valve body 33 of the pouring valve 8 does not move from the valve closed position to the valve open position. Therefore, by storing the key member 32 in a place out of reach of infants, it is possible to reliably prevent the hot water from being dispensed by infants.

Fig. 13 shows a water server with a key according to a third embodiment of the present invention. In the first embodiment and the second embodiment, the hot water pouring valve 8 adopts 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. In the third embodiment, an electromagnetic on/off valve opened by energization is employed as the hot water pouring valve 8 . Hereinafter, the same code|symbol is attached|subjected to the part corresponding to 1st Embodiment, and description is abbreviate|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 energized. A hot water dispensing operation switch 61 is provided in the housing 1 as a hot water dispensing operation unit 9 operated by a user to open the hot water dispensing valve 8 .

In addition, this water server includes a key member 32 configured to be able to be transported independently from the housing 1, and a hot water dispensing valve 8 by operation of the hot water dispensing operation switch 61 only when the key member 32 is present. ) is opened, and has a child proof means 41 that prevents the hot water dispensing valve 8 from being opened even when the hot water dispensing operation switch 61 is operated in the absence of the key member 32 .

The child proof means 41 includes a key sensor 62 for detecting the presence or absence of the key member 32, and a hot water dispensing valve 8 based on signals input from the key sensor 62 and the hot water dispensing operation switch 61. ) has an electronic control device 63 for controlling the The electronic control device 63 is electrically connected to the key sensor 62 , the hot water dispensing operation switch 61 , and the hot water dispensing valve 8 . The key member 32 is, for example, a card key in which a contactless IC chip is embedded, and 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 de-energizes the hot water dispensing valve 8 even if the hot water dispensing operation switch 61 is operated, while the key When the sensor 62 detects the key member 32, it is comprised so that electricity may be supplied to the hot water pouring valve 8 according to operation of the hot water pouring operation switch 61. FIG.

In the keyed water server of this third embodiment, when the key member 32 is not present, even if the hot water pouring operation switch 61 is operated, the hot water pouring valve 8 is not energized. That is, even if the infant operates the water server in various ways, hot water is not dispensed unless the key member 32 is not present. Therefore, by storing the key member 32 in a place out of reach of infants, it is possible to reliably prevent the hot water from being dispensed by infants, and it is possible to very effectively prevent an infant burn accident.

Moreover, like 3rd Embodiment, even when employ|adopting for the hot water pouring valve 8 the electromagnetic on-off valve opened by energization, like 1st and 2nd embodiment, the insertion port which inserts and removes the key member 32. In the state where 42 is formed and the key member 32 is inserted into the insertion port 42 , the user's operating force is transmitted to the hot water dispensing operation switch 61 , while the key member 32 is inserted into the insertion port 42 . ), it is also possible to configure the child proof means 41 so that the user's operating force is blocked from being transmitted to the hot water pouring operation switch 61 .

You may provide the child proof means 41 of each said embodiment not only on the warm water side but also on the cold water side. That is, the cold water dispensing valve 4 is opened by the operation of the cold water dispensing operation unit 5 only when the key member 32 is present, and cold water is poured out even when the cold water dispensing operation unit 5 is operated in the absence of the key member 32 . In order that the valve 4 may not be opened, you may add and provide the child proof means 41 of the same structure as the hot water side on the cold water side. In this way, it becomes possible to also reliably prevent the injection of cold water by an infant, and it becomes possible to prevent very effectively the accident of immersion into the floor by the mischief of an infant.
