Description

[0001] HOT WATER APPARATUS [0002]

The present invention relates to an instantaneous hot water generating apparatus that does not need to store hot water heated in a water tank in advance, and more particularly, to a hot water generating apparatus capable of heating and supplying only a necessary amount of hot water for easy hygienic management.

1, the hot water supply device includes a hot water tank 100, a cold water inlet 101 connected to the lower half to supply water into the hot water tank, A heating valve 110 for warming water, an air valve for artificially discharging the air inside, a safety valve 120 for maintaining the internal pressure at an appropriate pressure, Lt; / RTI >

In view of the operating state of the hot water supply device, the water that has first entered the cold water inlet 101 fills the hot water tank 100, and the filled water is heated by the heating device 110.

The heated water is discharged through the hot water supply port 105 when the user opens the water supply valve (not shown), and the cold water flows in through the cold water inlet port 101 as hot water is discharged. The introduced cold water is further heated by the heating mechanism 110 and raised to an appropriate temperature.

However, if the user does not use the hot water stored in the hot water tank for a long time, the hot water can be gradually cooled by performing the heat exchange with the atmosphere through the housing of the hot water tank. In this case, if the hot water is lowered to a certain temperature or lower, the heating mechanism is repeatedly operated to reheat the hot water, so that a fuel cost is further generated.

In addition, since the water in the hot water tank must be kept warm even when not in use, pathogenic bacteria are easily formed and unnecessary power consumption is generated.

In order to solve the above problem, recently, an instantaneous hot water generation method has been adopted. In this method, a small amount of water in a pipeline is short-circuited by using an initial high power without a hot water tank at the time of using hot water A few seconds), and then, after a gentle heating step, the temperature is maintained at the appropriate temperature.

The instantaneous hot water generating device includes heating modules 210 and 220 and an electric heater 230 as shown in FIG. The heating modules 210 and 220 are provided with a water inlet 211 at one side and a water outlet 213 at the other side and a flow passage 215 through which the raw water flowing through the water inlet 211 flows can be formed inside do.

An air vent hole 217 is formed in the heating modules 210 and 220 to discharge bubbles generated by raw water flowing in the heating modules 210 and 220. The air vent hole 217 is formed in the first water tray 210 and adjacent to the water outlet 213 formed in the first water tray 210.

More specifically, the heating modules 210 and 220 include a first water tray 210 and a second water tray 220. The first water tray 210 and the second water tray 210 are formed in a rectangular shape, but have a predetermined depth to allow the raw water to flow.

However, such instantaneous hot water generating apparatus also has a structure in which residual water which is not heated usually remains in the instantaneous hot water apparatus at all times, and microorganisms and the like can easily reproduce while not being heated.

Therefore, there is a need to develop a technique for preventing residual water from remaining in the hot water generator after supplying hot water.
