Drinking water dispensers (referred to as drinking water dispensers or water servers) are known (eg patent documents) Reference 1).

  However, in a conventional drinking water dispenser, when a container containing drinking water is newly replaced, cold water or hot water drinking water is extracted after a certain period of time (for example, 30 to 60 minutes). Even then, there was a case where the target temperature was not cold water or hot water.

Further, the drinking water extracted from the container containing the drinking water once enters the cold water tank and is supplied from here to the hot water tank through the water supply pipe. If the amount of drinking water supplied to the hot water tank is not accurately controlled according to the amount supplied and the amount of drinking water in the cold water tank, the amount of drinking water in the cold water tank and the amount of hot water in the hot water tank will always be There was a problem that the optimum state was not achieved, and the hot water flowed back and returned to the cold water tank.

A hot water tank installation section 7 for installing the tank 6 is disposed, and on the side surface of the dispenser main body 1, extraction sections 8a and 8b (safety valves) configured by an extraction valve or the like that can extract cold water Wa or hot water Wb are provided. Also, a cup supply unit 9 containing a disposable paper cup K or the like is provided between the extraction units 8a and 8b.

  The cup supply unit 9 includes a cylindrical part 9a disposed between the extraction units 8a and 8b, and an elastic member 9b such as a spring that sequentially pushes up the stacked paper cups K. The paper cup K is taken out one by one from the opening 9c formed between 8b, and the cold water Wa or the hot water Wb is extracted from the extraction part 8a or 8b so that it can be used.

  The cold water tank 4 is integrally formed of a sanitary material such as stainless steel or a resin material (for example, a material in which an antibacterial agent is blended with polypropylene or the like is preferable). A cooling mechanism 10 for cooling the drinking water Wx is installed, and a water supply pipe 11 to the hot water tank 6 is provided.

  The hot water tank 6 is formed in a predetermined size by one metal material selected from iron, stainless steel, and aluminum alloy having a large electric resistance, and the hot water tank installation section 7 for installing the hot water tank 6 includes: An electromagnetic induction heating device 12 for induction heating the drinking water Wx in the hot water tank 6 is installed.

  The electromagnetic induction heating device 12 knows the temperature of the drinking water Wx in the hot water tank 6 and turns on / off a temperature control device (not shown) to keep the hot water Wb in the hot water tank 6 at a constant temperature ( For example, it can be held at around 95 ° C.

  In the cold water tank 4, a material having a small buoyancy that opens and closes the extraction port of the drinking water supply container 2 and opens and closes the supply port of the water supply pipe 11 to the hot water tank 6 (for example, a foam material such as urethane foam). Alternatively, a float valve 13 formed of a hollow material is provided, and the water supply pipe 11 connecting the cold water tank 4 and the hot water tank 6 is reversely connected to prevent the heated hot water from flowing back into the cold water tank 4. A stop valve 14 is provided.

  The cold water tank 4 installed in the cold water tank installation unit 5 and the hot water tank 6 installed in the hot water tank installation unit 7 are covered with a heat insulating material 15 formed of a foam material or the like.

  In addition, the cooling mechanism 10 is configured to cool the cold water Wa in the cold water tank 3 by disposing an evaporator 16 constituted by a cooling pipe filled with a refrigerant gas such as freon gas on the side surface of the cold water tank 3. The evaporator 16 is connected to the compressor 17 and the condenser 18.

  Further, the cold water tank 4 and the hot water tank 6 are provided with temperature sensors (not shown), and the temperature of the cold water Wa or the hot water Wb in the cold water tank 4 and the hot water tank 6 is set to one surface of the dispenser body 1.

  The installation unit 8c for installing the paper cup K or the like below the extraction units 8a and 8b is provided with a recess that can accommodate the overflowing cold water Wa or hot water Wb. A drain pipe connected to a drain container (not shown) provided on the bottom side is connected, so that cold water Wa or hot water Wb overflowing the installation part 8c can be recovered and discharged. Reference numeral 20 denotes a sealing metal fitting of the hot water tank 6, 21a denotes a high-pressure refrigerant pipe, and 21b denotes a constant-pressure refrigerant pipe.

  Next, the operation method of the drinking water dispenser which consists of the above structures is demonstrated. When the dispenser body 1 is used, when the drinking water supply container 2 containing a predetermined volume of drinking water (mineral water or the like) Wx is placed on the container placement portion 3 of the dispenser body 1, the drinking water Wx is first The liquid flows into the cold water tank 4, the amount of liquid is adjusted by the float valve 13, and then flows into the hot water tank 6 through the water supply pipe 11.

  The drinking water Wx that has flowed into the cold water tank 4 and the hot water tank 6 is cooled to a predetermined temperature (for example, around 5 ° C. by 10 ° C. or less) and heated (for example, 70 ° C.) by the cooling mechanism 10 and the electromagnetic induction heating device 12. ° C to 95 ° C) and ready for use. In this embodiment, when normal temperature drinking water Wx is used, the cold water Wa can be used in about 30 to 45 minutes, and the hot water Wb can be used in about 20 minutes. In the case of the hot water Wb, the hot water tank is used. Since the temperature of the hot water in 6 is constantly detected by a temperature sensor and the output of the electromagnetic induction heating device 12 is adjusted by the temperature control device and the power is turned on and off, it is effective for energy saving measures and also consumes power. Less. Moreover, the temperature display of the cold water Wa and the hot water Wb is displayed on the display means 19 attached to a part of the surface of the dispenser body 1 as described above.

  In this embodiment, in particular, the warm water Wb is heated by the electromagnetic induction heating device 12, so that it can be heated to a set temperature in a shorter time than a conventional heating device such as a temperature heater, and is always at a constant temperature. Wb can be held.

  When extracting the cold water Wa or the hot water Wb, the paper cup K or the like is extracted from the cup supply unit 9 one by one and held on the installation unit 8c, and the cold water Wa or the hot water Wb is extracted from the extraction units 8a and 8b. It is intended to be used.

  As described above, the cooling mechanism 10 for cooling the drinking water Wx in the cold water tank 4 is installed in the cold water tank installation section 5 and the water supply pipe 11 to the hot water tank 6 is disposed, and the hot water tank 6 is electromagnetically induced. Drinking water supplied from the drinking water supply container 2 into the hot water tank 6 because the electromagnetic water heating device 12 for heating the hot water tank 6 is installed in the hot water tank installation section 7 while being formed of a metal material corresponding to heating. Wx can be heated to a set temperature in a short time and kept warm, and cold water and hot water can be extracted and used in a stable state at all times.

  In addition, since the electromagnetic induction heating device 12 is used as a heating means, it can be used with peace of mind even when used in ordinary homes or offices, can be easily maintained, and is a drinking water dispenser excellent in workability and economy. It can be.

It is a whole perspective view of the drinking water dispenser which implemented this invention. It is XX arrow sectional drawing of FIG. It is a principal part expanded sectional view.
