Description

Instant heating water heater {INSTANTANEOUS WATER HEATING APPARATUS}

The disclosed subject matter relates to an instantaneous water heater installed in various places, such as coffee shops, convenience stores, restaurants, offices, and the like, to supply high-temperature hot water by heating purified raw water when necessary.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and it is not admitted that the material described in this section is prior art.

In general, water heaters for supplying hot water are installed in places such as coffee shops, convenience stores, restaurants, and offices. Such a water heater includes a hot water tank, an inlet line for storing raw water supplied from the water supply through a water filter and stored in the hot water tank, a heater installed in the hot water tank to heat the water in the hot water tank to a set temperature, and a temperature of hot water in the hot water tank. It includes a temperature sensor for measuring and a water outlet line for dispensing hot water heated by a heater in the hot water tank.

Conventional water heaters measure the temperature of the hot water in the hot water tank and always maintain the temperature of the hot water in the hot water tank at the set temperature, so there is a problem of high power consumption and a problem that the temperature of the hot water discharged is not constant.

As a solution to this problem, a high-temperature water heater equipped with an instantaneous heating function has been developed by installing an instantaneous heating device in the water outlet line of the hot water tank to immediately supply hot water at a desired temperature to the user.

As an example of such a water heater, Korean Patent Registration No. 10-0775599 (published on November 9, 2007) discloses a room temperature water tank for storing room temperature water, a warm water tank for storing room temperature water at a higher temperature than room temperature water through heating by a heating means, A control unit for setting the temperature of water desired by the user, an instantaneous heating device for receiving and heating the water supplied from the room temperature water tank or the lukewarm water tank, and then supplying the water to the outside; A water heater having an instantaneous heating function including a control unit controlling a flow path so that water having a temperature lower than the temperature set by the operation unit and closest to the temperature set by the operation unit is provided to the instantaneous heating device.

In addition, Korean Patent Publication No. 10-2012-0011924 (published on February 9, 2012) discloses a filter unit for filtering raw water obtained from the outside, and hot water supplied with purified water from the filter unit. ), an instantaneous hot water module including a heating unit for instantaneously heating, a cold water container connected to the instantaneous hot water module, and to which the heated hot water is delivered when the heated hot water is lower than a set temperature, and a cold water container connected to the cold purified water container An instantaneous heating type water purifier includes a water outlet for dispensing cold water and purified water to the outside and discharging the heated hot water to the outside when the hot water connected to the instantaneous hot water module is above a set temperature.

However, in the case of the conventional instantaneous heating type water heater as described above, it takes a certain amount of time to heat purified raw water to a set temperature, and it is applicable only to a relatively small water output capacity, and an instantaneous heating device must be installed separately in addition to the hot water tank. There was a problem that it was difficult to configure more compactly.
