Description

[0001] The present invention relates to a commercial use water dispenser having a preheating function,

In particular, the present invention relates to a water dispenser for supplying hot water of a certain temperature to a customer in a small-scale business. In particular, a heater is installed in a lower part of a hot water tank, The water is heated by the heater at the same time when the water is introduced into the discharge or hot water tank so that the amount of hot water continuously supplied is increased to continuously discharge a large amount of hot water even in a small volume, Dispenser.

Generally, a water dispenser is installed in a convenience store, a restaurant, a coffee shop, and the like to supply hot water of a certain temperature to a consumer. Such a water dispenser includes a hot water tank provided inside the case for heating water containing water, and a hot water valve provided outside the case for allowing water in the hot water tank to flow out through a discharge port.

For example, JP-A-10-0851825 (a drainage device for a water heater) has been proposed as a conventional water dispenser according to the above configuration. However, in such a conventional hot water valve cock, Water must be supplied through a hot water valve cock through a pulling or pushing valve. Since the amount of water to be supplied is not determined once, the hot water must be received while checking with the naked eye. It is susceptible to safety accidents Because of the nature of the shops such as restaurants, coffee shops, etc., guests are caught in a busy time zone.

Particularly, in the conventional water dispenser, water is supplied from the outside to the hot water tank only when the hot water stored in the hot water tank is discharged and the water level of the hot water tank is below a certain level, and then heated by the heater. Accordingly, while the water is heated by the heater, the supply of the hot water is interrupted, so that the amount of hot water that can be continuously supplied is reduced. Of course, the hot water tank can be enlarged to increase the amount of hot water that can be continuously supplied, but the water dispenser installed in a shop such as a coffee shop has a limitation in increasing the size. That is, in the case of a water dispenser for business use, since the size of the water dispenser is small due to the restriction of the installation space, the amount of hot water that can be continuously supplied is not large, and the amount of hot water continuously supplied from the water dispenser, It is only 2 liters, and consumers are complaining about it.

On the other hand, the conventional water dispenser described above is often constructed so as to supply only hot water. Therefore, when cold water is required, a separate water cooler or water purifier should be used. Accordingly, the installation cost is further increased by installing an additional water cooler in addition to the water dispenser.

Of course, a water dispenser capable of supplying cold water and hot water at the same time has been developed, but the size of the water dispenser is larger than that of hot water, and the price is high. Particularly, in the case of a water dispenser for business use, there is a limitation in the size of the water dispenser due to the limitation of installation space, and a limited amount of water dispenser for business use has a problem that the amount of hot water to be continuously supplied is not large.

And a hot water temperature display unit 52 for displaying the temperature of the hot water discharged through the hot water discharge port 12.

The heater 25 is controlled so as to preheat or heat the water in the hot water tank 20 at the same time when the hot water is discharged through the hot water discharge port 12 or water flows into the hot water tank 20 , And the heating unit is disposed at a lower side of the hot water tank 20, specifically, at a height of 20% or less with respect to the total height of the hot water tank 20.

Preheating in the present invention means that the water is heated without changing the temperature of the water stored in the hot water tank 20. In the conventional products, although the temperature inside the hot water tank must be changed, the water is heated. However, when the hot water is discharged from the hot water tank or the water is introduced into the hot water tank, the heater operates regardless of the change in the water temperature do.

The water supply unit 30 includes a cold water solenoid valve 31 for allowing water to flow out to the cold water discharge port 11, a hot water supply solenoid valve 32 for supplying water to the hot water tank 20, Water supplied from the outside of the case 10 through the water supply pipe 35 is supplied to the cold water solenoid valve 31 or the warm water solenoid valve 32 and the cold water discharge port 11 or the hot water discharge port A pressure reducing valve (33) configured to change a water quantity and a water pressure supplied by forward or reverse rotation such that the amount of water coming out through the water supply pipe (12) coincides with the amount of water supplied through the water supply pipe (35) And a check valve (34) disposed between the hot water tank (32) and the hot water tank (20) to prevent the hot water in the hot water tank (20) from flowing backward.

On the other hand, a cold water valve or a hot water valve operating in conjunction with the cold water solenoid valve 31 and the warm water solenoid valve 32 may be installed behind the cold water discharge port 11 and the hot water discharge port 12. In this case, the cold water valve and the hot water valve are preferably composed of a solenoid valve so as to be opened or closed in response to a signal from the control box 40.

The hot water temperature display unit 52 displays a temperature of 2 to 3 占 폚 lower than the actual temperature of the hot water sensed by the hot water sensor 23 installed in the middle part of the hot water tank 20, Is displayed. Considering that the hot water in the hot water tank 20 is cooled to some extent while being discharged through the hot water discharge port 12, a temperature approximately equal to the actual temperature of the hot water discharged through the hot water discharge port 12 is lower than the hot water temperature And displayed on the display unit 52, thereby improving the reliability of the consumer.

The water dispenser of the present invention configured as described above continuously supplies a larger amount of hot water so that the water level in the hot water tank is always kept constant and the hot water temperature in the hot water tank is not lowered.

The water dispenser of the present invention connects an external water pipe to a pressure reducing valve located at the back of the case to supply water from the outside to the inside of the water dispenser. In this state, when the water supply is started by pressing the operation button 51 of the front panel 50 provided in the case 10, the control box 40 sends an open signal to the water supply solenoid valve 32 to open the water supply pipe 35, Water is supplied to the hot water tank 20 through the pressure reducing valve 33 and the hot water solenoid valve 32. [ When the water level of the hot water tank 20 becomes approximately 80 to 90%, the control box 40 sends a shutoff signal to the hot water supply solenoid valve 32 to stop hot water supply. The control box 40 controls the heater 25 provided in the hot water tank 20 by pressing the operating button 51 to start water supply or to open the hot water solenoid valve 32 at an early point To start preheating the water. Thereafter, when the temperature of the hot water in the hot water tank 20 reaches the set temperature, the temperature sensor 23 provided in the hot water tank 20 sends a signal to the control box 40, Stops the hot water heating by sending an operation stop signal to the heater 25.

Thereafter, when the user presses the operation button 51 of the front panel 50 provided in the case 10 to obtain the hot water, the hot water supply solenoid valve 32 is opened so that water in the water supply pipe 33 flows into the hot water tank 20, and hot water from the hot water tank 20 is discharged through the hot water discharge port 12 by a predetermined amount. At this time, the pressure reducing valve 33 controls the water supply amount so that the amount of water discharged through the hot water discharge port 12 and the amount of water supplied to the hot water tank 20 through the hot water supply solenoid valve 32 become equal .

The hot water is discharged through the hot water discharge port 12 and the heater 25 in the hot water tank 20 is operated to preheat the water flowing into the hot water tank 20, Thereby moving to the upper side of the hot water tank 20. Accordingly, the water in the hot water tank 20 is divided into a high temperature section in the upper layer and a low temperature section in the lower layer, and water in the high temperature section is discharged to the hot water discharge port 12. As described above, since the heating by the heater 25 is performed simultaneously with the discharge of the hot water, hot water of 5 to 6 liters or more can be continuously supplied.

  When the user presses the operation button 51 of the front panel 50 to obtain the cold water, the cold water solenoid valve 31 is opened and the external water supplied through the water supply pipe 33 flows into the case 10, And is discharged through a cold water discharge opening 11 provided in the discharge opening 11.
