Description
Technical Field
The present invention relates to a water dispenser that allows cold water to be drunk or warm water to be discharged based on the cold water or the warm water, in response to a request from a user.
Background
A water dispenser is known which produces cold water from water filled in a container such as a water supply tank or the like, or produces warm water in addition to the cold water, not from tap water, and supplies the cold water to a user, and as an example of such a water dispenser, a water dispenser described in patent document 1 is given. The water dispenser of patent document 1 includes a cold water tank, a warm water tank, and a replaceable water supply tub for supplying water to the cold water tank. Since the water supply tub is not cooled, the water therein is at a normal temperature. In addition, the water in the water supply tub gradually decreases as it flows out of the water dispenser for drinking. Also, the water supply tub is usually carried to a water dispenser installation site by a specialized practitioner and replaced there. At the time of replacement, the joint portion of the cold water tank connected to the water supply tank is also cleaned.
In such a water dispenser, it is necessary to periodically sterilize a cold water path including a cold water tank. This is because, for example, if the cleaning of the joint portion between the water supply tank and the cold water tank is insufficient, microorganisms adhering thereto invade the water supply tank and proliferate in the water supply tank at normal temperature, and as a result, there is a possibility that water containing microorganisms is also supplied from the water supply tank to the cold water tank. In order to sterilize microorganisms flowing into the cold water tank from the water supply tank at normal temperature, it is necessary to reliably sterilize the cold water tank and the like at a predetermined frequency. In addition, including the case of patent document 1, the sterilization is often performed by sterilizing high-temperature water obtained from a high-temperature water tank by feeding the high-temperature water into a cold-water tank.

Problems to be solved by the invention
On the other hand, since the operation of the water dispenser is restricted during the high-temperature water sterilization and several hours after the high-temperature water sterilization, and a large amount of electric power is consumed during the high-temperature water sterilization and the subsequent re-cooling of the cold water tank, it is also desired to reduce the frequency of the high-temperature water sterilization.
Means for solving the problems
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water dispenser and a method of supplying water to the water dispenser, which can maintain a good sanitary state for a long time.
In order to achieve the above object, according to the present invention, there is provided a water dispenser comprising: a cold water tank for storing cold water; a water supply container connected to the cold water tank and enclosing water to be supplied to the cold water tank; and a tank capacity detection means for detecting whether the volume of the space formed in the cold water tank is greater than or less than the internal volume of the water supply container, the volume of the cold water tank being greater than the internal volume of the water supply container, and when the tank capacity detection means detects that the volume of the space formed in the cold water tank is greater than the internal volume of the water supply container, all water in the water supply container connected to the cold water tank is supplied to the cold water tank.
Further, in order to achieve the above object, there is provided a method of supplying water to a water dispenser according to the present invention, comprising: preparing a water supply container for sealing water to be supplied to a cold water tank of the water dispenser; confirming that the space capacity formed in the cold water tank is greater than the water quantity in the water supply container; and connecting the water supply container to the inlet of the cold water tank, and supplying all water in the water supply container to the cold water tank through the inlet.
ADVANTAGEOUS EFFECTS OF INVENTION
Accordingly, since all the water in the tub is supplied to the cold water tank when the water supply container is replaced, the possibility that water containing microorganisms growing at normal temperature is supplied from the water supply container to the cold water tank is completely eliminated. As a result, the cold water tank can be maintained in a good sanitary state for a long period of time, and the frequency of sterilization of the hot water in the cold water tank can be reduced.

Fig. 1 is a schematic diagram showing a configuration of a water dispenser according to an embodiment of the present invention.
Detailed Description
A water dispenser 10 according to embodiment 1 of the present invention will be described below with reference to fig. 1.
The drinking fountain 10 according to embodiment 1 is configured such that the cold water and the warm water for drinking are caused to flow out from the tank located inside in accordance with the user's request. Therefore, the water dispenser 10 includes: a cold water tank 11; a warm water tank 12 communicated with the cold water tank 11; a water supply tank 14 connected to an inlet portion at the top end of an inlet pipe line 11a of the cold water tank 11 through a joint 13; a tank capacity detection mechanism 15 that detects whether a capacity of a space formed in the cold water tank 11 is larger or smaller than an inner capacity of the water supply tank 14; a plurality of solenoid valves 16 to 19; a control unit (20); and a frame body not shown in the figure. The control unit 20 is electrically connected to the plurality of solenoid valves 16 to 19 and the tank capacity detection mechanism 15 through a not-shown electric wire. Although not shown, the water dispenser 10 further includes: a cooling device for cooling the cold water tank 11; and a heating device for heating the warm water tank 12.
The water supply tank 14, the cold water tank 11, and the hot water tank 12 are arranged in the vertical direction as shown in fig. 1, and water is supplied to the water dispenser 10 due to a difference in water level. In the water dispenser 10 of the present embodiment, the entire amount of water in the water supply tank 14 is supplied to the cold water tank 11 at the stage when the water supply tank 14 is connected to the cold water tank 11, and the empty water supply tank 14 is connected to the cold water tank 11.
The water dispenser 10 is provided with a cold water outlet 21 and a hot water outlet 22, which are outlets for cold water and hot water, and a tray (not shown) for placing a cup or the like is provided below these outlets. Further, a cold water button (not shown) and a hot water button (not shown) are disposed on the outer surface of the housing in the vicinity of the cold water outlet 21 and the hot water outlet 22. A cold water injection solenoid valve 16 and a hot water injection solenoid valve 17 are disposed upstream of the cold water outlet 21 and the hot water outlet 22, respectively. When the user presses the cold water button, the cold water injection solenoid valve 16 is opened to discharge cold water from the cold water outflow port 21. Similarly, when the user presses the hot water button, the hot water injection solenoid valve 17 is opened to allow hot water to flow out from the hot water outlet 22.
The water supply tub 14 in the present embodiment is made of synthetic resin, and water in a good hygienic state sealed in a factory of a beverage manufacturing company is contained therein. When the water supply tub 14 is connected to the cold water tank 11, all water contained therein is supplied to the cold water tank 11. One member 13a of the joint 13 is fixed to a top end of a neck of the water supply tub 14, and a water injection port of the top end of the neck is sealed by the one member 13 a.
The water supply tub 14 encloses a smaller amount of water than the capacity of the cold water tank 11. In other words, the cold water tank 11 has a capacity capable of containing a larger amount of water than the amount of water filled in the water supply tub 14.
The cold water tank 11 includes an inlet pipe 11a extending upward so as to be connectable to the water supply tank 14. The other member 13b of the joint 13 is fixed to the tip of the inlet pipe line 11 a. The joint 13 is a well-known type of joint and therefore will not be described in detail, but is configured such that while the one member 13a and the other member 13b of the joint 13 are mechanically connected by being screwed together, a portion (not shown) of the one member 13a provided in the water supply tub 14, which is easily broken, is pierced by a sharp distal end of a tubular piercing member (not shown) provided in the other member 13b, thereby achieving fluid connection.
A water supply solenoid valve 18 for opening and closing the inlet line 11a is also provided in the inlet line 11a of the cold water tank 11. The water supply solenoid valve 18 is electrically connected to the controller 20, and the operation thereof is controlled by the controller 20.
The cold water tank 11 includes an outlet 11b at the bottom thereof, and a cold water outlet line 23 is connected to the outlet 11 b. A cold water outflow port 21 is provided at the top end of the cold water outflow pipe 23, and a cold water injection solenoid valve 16 for opening and closing the pipe is disposed in the cold water outflow pipe 23 upstream of the cold water outflow port 21. The cold water injection solenoid valve 16 is electrically connected to the control unit 20, and its operation is restricted according to the water storage amount of the cold water tank 11. That is, when the amount of cold water stored in the cold water tank 11 is small, the control unit 20 does not allow the cold water injection solenoid valve 16 to be opened even if the cold water button is pressed, and the cold water injection solenoid valve 16 continues to be closed, so that cold water does not flow out.
The cold water tank 11 is provided with a vent 24 for opening the inside of the cold water tank 11 to the atmosphere so that water from the water supply tank 14 can easily flow in. A filter unit 25 for preventing dust and microorganisms from entering the cold water tank 11 is attached to the air vent 24. The filter element of the filter unit 25 uses a HEPA filter.
The tank capacity detection means 15 includes a 1 st water level sensor 15a attached to the cold water tank 11. The 1 st water level sensor 15a is configured to detect whether the water level of the water stored in the cold water tank 11 is above or below the 1 st water level set in advance. Therefore, the 1 st water level sensor 15a is electrically connected to the control unit 20 and a water level indicator lamp (not shown) provided on the front surface of the housing of the water dispenser 10. Fig. 1 shows a state in which the water level of the cold water tank 11 is lower than the 1 st water level.
The 1 st water level is a water level set such that a volume of a space formed inside the cold water tank 11 becomes more than an amount of water enclosed in the water supply tub 14 when a water level of water stored in the cold water tank 11 is lower than the 1 st water level. Accordingly, when the 1 st water level sensor 15a detects that the water level of the cold water tank 11 is lower than the 1 st water level, all water enclosed in the water supply tub 14 can be supplied to the cold water tank 11, so that the control part 20 opens the water supply solenoid valve 18.
On the other hand, when the water level of the cold water tank 11 is detected to be the 1 st water level or more, the volume of the space formed in the cold water tank 11 at this time is smaller than the inner volume of the water supply tub 14, and the control part 20 closes the water supply solenoid valve 18 so that water is not supplied from the water supply tub 14 to the cold water tank 11. If the water level of the cold water tank 11 is not lower than the 1 st water level, if water is supplied from the water supply tank 14 to the cold water tank 11, water overflows from the vent 24 of the cold water tank 11, and if not, water at normal temperature remains in the water supply tank 14 as in the conventional case, and the possibility of proliferation of microorganisms cannot be eliminated. In the present embodiment, in order to prevent such a situation, the 1 st water level sensor 15a detects the volume of the space formed in the cold water tank 11, and the control unit 20 opens the water supply solenoid valve 18 only when the cold water tank 11 can receive the entire water in the water supply tub 14.
The tank capacity detection mechanism 15 of the present embodiment further includes a 2 nd water level sensor 15 b. The 2 nd water level sensor 15b is configured to detect whether the water level of the water stored in the cold water tank 11 is above or below a preset 2 nd water level lower than the 1 st water level. The 2 nd water level is set for detecting a water shortage state of the cold water tank 11. When the 2 nd water level sensor 15b detects that the water level of the water stored in the cold water tank 11 is lower than the 2 nd water level, the controller 20 turns on a water shortage lamp (not shown) provided on the front surface of the housing to indicate a water shortage state. At this time, even if the cold water button is pressed, the control unit 20 does not allow the cold water injection solenoid valve 16 to be opened. In the present embodiment, when a predetermined time has elapsed since the water shortage lamp was turned on, the control unit 20 sounds an alarm sound for notifying the water shortage state.
Although not shown, a cooling pipe to which a cooling device is attached is wound around the outside of the cold water tank 11. The cooling device is of a known type utilizing compression and expansion of a cooling medium, and functions as an evaporator by winding a cooling pipe attached to the cold water tank 11.
The cold water tank 11 and the warm water tank 12 disposed therebelow are communicated with each other through a 1 st connecting pipe 26 having a flange-like portion at an upper end portion thereof. Water is supplied from the cold water tank 11 to the warm water tank 12 through the 1 st connection line 26. The cold water tank 11 and the warm water tank 12 are also connected by the 2 nd connecting line 27. However, a thermal valve 19 for opening and closing the 2 nd connection line 27 is disposed in the 2 nd connection line 27, and the 2 nd connection line 27 is normally closed by the thermal valve 19. When the hot valve 19 is opened, the 1 st connection line 26 and the 2 nd connection line 27 form a circulation path between the cold water tank 11 and the hot water tank 12. In the present embodiment, a downward flow of water flows through the 1 st connecting line 26, and an upward flow of water flows through the 2 nd connecting line 27.
An outlet 12b is provided at an upper portion of the hot water tank 12, and a hot water outlet line 28 is connected to the outlet 12 b. A hot water outlet 22 is provided at the top end of the hot water outlet pipe 28. The hot water injection solenoid valve 17 is disposed in a hot water outflow pipe 28 on the upstream side of the hot water outlet 22 to open and close the pipe.
An electric heater, not shown, is attached to the outer surface of the bottom surface of the hot water tank 12. The electric heater is intermittently operated by the control unit 20 so that the temperature of the hot water supplied to the drinker becomes a desired temperature. In the present embodiment, the high-temperature water on the cold water tank 11 side is sterilized using the high-temperature water in the hot water tank 12, but the electric heater is also operated at this time.
The high-temperature water on the cold water tank 11 side is sterilized by replacing the cold water in the cold water tank 11 with high-temperature water. Therefore, the hot valve 19 is opened by a command from the control unit 20, and the 2 nd connecting line 27 is opened, so that the electric heater is continuously operated to continuously heat the hot water in the hot water tank 12. In this way, the hot water in the hot water tank 12 circulates between itself and the cold water tank 11 by natural convection through the 2 nd connection line 27 and the 1 st connection line 26. By continuously operating the electric heater for a certain time or more, the temperature of the water in the cold water tank 11 can be raised to 90 ℃ or more, for example, which is suitable for sterilization. By sterilizing the high-temperature water in the cold water tank 11, not only the water in the cold water tank 11 is sterilized, but also the inner surface of the cold water tank 11 that is in contact with the high-temperature water and the inner surface of the pipe extending from the cold water tank 11 are sterilized, and the portion of the cold water tank 11 that becomes high in temperature by heat conduction of the high-temperature water and the portion around the high-temperature water are sterilized.
According to the water dispenser 10 of embodiment 1, when the water supply tub 14 is replaced, all the water in the tub is supplied to the cold water tank 11. Therefore, the possibility that water containing microorganisms that proliferate in a normal temperature environment is supplied from the water supply tub 14 to the cold water tank 11 is completely eliminated. As a result, the good sanitary state of the cold water tank 11 is maintained for a long period of time, and the frequency of sterilization of the high-temperature water in the cold water tank 11 can be reduced. Although the frequency of high-temperature water washing has been often set once a day in the past, according to the water dispenser 10 of the present embodiment, even if the frequency of high-temperature water sterilization is once a week, it has been confirmed that the sanitary state of the cold water flowing out is maintained well.
Next, a method of supplying water to the water dispenser 10 according to embodiment 2 of the present invention will be described. Here, description will be given by taking the water dispenser 10 according to embodiment 1 as an example.
Initially, a water supply tub 14 filled with water to be supplied to the cold water tank 11 is prepared.
Next, it is confirmed that the volume of the space formed in the cold water tank 11 is larger than the amount of water in the water supply tub 14. In the present embodiment, this is performed by the control unit 20 based on a signal from the 1 st water level sensor 15a of the tank capacity confirmation mechanism of the water dispenser 10. Thereafter, the control unit 20 opens the water supply solenoid valve 18 disposed in the inlet line 11a extending from the cold water tank 11.
Next, the empty water supply tub 14 connected to the cold water tank 11 is removed from the inlet port at the tip end of the inlet pipe line 11a of the cold water tank 11. In this case, it is preferable to clean the joint 13 of the inlet.
Next, the prepared new water supply tub 14 is inverted, and the top end of the neck of the water supply tub 14 is connected to the inflow portion of the top end of the inlet pipe 11a of the cold water tank 11. This connection is made by screwing one member 13a of the joint 13 fixed to the top end of the neck of the water supply tub 14 into the other member 13b of the joint 13 fixed to the inlet port of the cold water tank 11. In addition, in the present embodiment, the water supply tub 14 is opened by connection using the structure of the joint 13 described above. The water in the water supply tub 14 is supplied to the cold water tank 11 when opened. In addition, since it is confirmed that the volume of the space formed in the cold water tank 11 is larger than the inner volume of the water supply tub 14, the entire water in the water supply tub 14 is supplied to the cold water tank 11 within about 60 minutes in the present embodiment. In this way, the water supply to the cold water tank 11 is terminated.
It will be appreciated that the time required for the entire water of the water supply tub 14 to be supplied to the cold water tank 11 varies depending on the capacity of the water supply tub 14, the bore of the tubular piercing member of the joint 13, and the like. For example, it is also possible to reduce the time required for water supply to several minutes or less by increasing the diameter of the piercing member of the adapter 13 or providing an air hole in the adapter 13.
As in embodiment 1, it is understood that the method of supplying water to the water dispenser according to embodiment 2 can maintain the good hygienic state of the cold water tank 11 for a long period of time, and can reduce the frequency of sterilization of the hot water in the cold water tank 11.
Other embodiments
Although the water dispenser 10 according to embodiment 1 is configured such that the opening and closing of the water supply solenoid valve 18 is controlled by the control unit 20 based on a signal from the 1 st water level sensor 15a of the tank capacity confirmation mechanism, an embodiment may be adopted in which the water supply solenoid valve 18 is not provided and a signal from the 1 st water level sensor 15a is displayed only on a water level display lamp. At this time, the replacer of the water supply tub 14 can determine whether to replace the water supply tub 14 according to the information of the water level display lamp.
Further, instead of the 1 st water level sensor 15a, a simple visual water level gauge may be provided in the cold water tank 11.
Although the water dispenser 10 including the control unit 20 and the water supply solenoid valve 18 is used in the method for supplying water to a water dispenser according to embodiment 2, the method for supplying water to a water dispenser may be an embodiment which does not include the control unit 20 and the water supply solenoid valve 18. At this time, the confirmation of the volume of the space formed in the cold water tank 11 is performed by the confirmation of the display of the water level display lamp or the like by the water supply tank changer, and as a result of the confirmation, when it is determined that the water supply tank is replaceable, the changer may connect the water supply tank to the cold water tank.
Although the empty water supply tub 14 after the water supply of the water dispenser 10 according to embodiment 1 is completed is continuously connected to the cold water tank 11, an embodiment may be adopted in which a lid for closing an inlet of the cold water tank 11 is provided so that the empty water supply tub 14 at the stage of completion of the water supply is isolated from the cold water tank 11.
Similarly, in the method for supplying water to a water dispenser according to embodiment 2, if all the water is supplied, the water supply tub 14 may be isolated from the cold water tank 11, and the inlet of the cold water tank 11 may be closed by a cover or the like.
Although the water supply tub 14 is opened while being inverted and connected to the inlet port of the inlet pipe line 11a of the cold water tank 11 in embodiment 2, the water supply tub 14 may be opened in an upright state. At this time, a joint having a flexible hose for communicating the outlet of the water supply tub 14 and the inlet of the cold water tank 11 is prepared, the water supply tub 14 opened in the upright state and the inlet of the cold water tank 11 are connected by the joint, and then the water supply tub 14 is lifted above the cold water tank 11 and inverted.
Although the water dispenser according to embodiment 1 is configured to selectively discharge cold water and warm water as required, it may be configured to discharge only cold water. The water dispenser at this time does not have a warm water tank and a pipeline and an electromagnetic valve related to the warm water tank. In addition, an electric heater for sterilizing high-temperature water is also installed on the cold water tank besides the cooling pipeline.
