Description

Electric instant water heater

The present invention relates to an instantaneous water heater, and more particularly, to an electric instantaneous water heater which saves water consumed by cold water by inserting an electric heating element into a hot water supply pipe and shortens the heating time of the incoming water. .

In general, the instant water heater is installed in a place equipped with a drainage system is configured to be used as hot water by instantaneous heating of the water flowing from the water supply or water pipes as needed.

The instant water heater is composed of various energy sources such as oil, gas, and electricity to heat the water. In the past, the main water heater uses a gas having a high ignition rate and a high exothermic temperature to minimize the heating time of the water. .

However, since the instantaneous water heater using the gas has a risk of explosion of the gas cylinder, it is necessary to secure a separate space for storing the gas cylinder in a safe place, and the inconvenience of replacement when the gas is exhausted, and the gas in a closed space such as a bathroom. Its use is decreasing due to the risk of human injury due to lack of oxygen due to leakage and gas combustion.

Therefore, in recent years, as a countermeasure for overcoming the problems of the conventional instantaneous water heater using the gas, the situation is increasing the use of the instantaneous water heater using electricity.

In general, the instantaneous water heater using electricity is composed of an outer case, a reservoir and a heat transfer part, and the water introduced into the reservoir is heated by contact with the heat transfer part that is heated through an applied power source, and the heated water is heated inside the reservoir due to convection of heat. It is configured to flow into hot water while circulating.

However, the existing electric instant water heater is composed of a tank storage type, and after the use of hot water, a considerable amount of heated water remains inside the reservoir, and as the time passes, the heat quantity of the water is insignificantly consumed. There is a problem in that energy efficiency is reduced because the newly introduced cold water must be reheated.

In addition, since the water is first heated from the water adjacent to the heat transfer unit located on one side inside the reservoir, and the heated water is circulated into the reservoir as a whole, heat is transferred, so that a relatively long time is heated to the hot water of the set temperature. There is a limitation in the configuration that a large amount of water discharged through the outlet pipe is unnecessarily wasted before the hot water is discharged.

Accordingly, the present invention has been made to solve the above problems, by heating the water flowing through the water pipe at the same time as a whole to shorten the heat discharging time of hot water, to minimize the unnecessary waste of waste water to save water and high The purpose is to provide an electric instant water heater to have energy efficiency.

In order to achieve the above object, the present invention provides an electric instant in which a cold water pipe for discharging water into the cold water is discharged into the cold water without being heated, and the hot water pipe for discharging the incoming water into the hot water is discharged into hot water. In the water heater, the heating element is provided in the same form along the longitudinal direction of the hot water pipe in the inside of the hot water pipe, and generates heat of high temperature due to the applied electricity to heat the water flowing into the hot water pipe; A temperature sensor provided at an inlet side of the hot water pipe into which the water flows, and measuring a temperature of the water flowing therein to determine whether the electric heating element is operated; It is characterized in that it comprises a pressure sensor is provided at the inlet side of the hot water pipe to which the water is introduced to measure the weight of the water introduced into the hot water pipe to determine whether the electric heating element is operated.

The water introduced into the water heater by the present invention configured as described above is heated at the same time as a whole through a hot water pipe containing the electric heating element is shortened the discharge time of hot water. Therefore, it saves water that is consumed unnecessarily before the hot water is discharged, and the maintenance cost is inexpensive as the power supply time of the electric heating element is shortened, and by controlling the operation of the electric heating element by measuring the temperature and weight of the water flowing into the hot water pipe. There is an effect of obtaining a safe and high energy efficiency.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic front view showing an internal configuration of an electric instant water heater installed in accordance with a preferred embodiment of the present invention in a water supply device provided in a typical bathroom, Figure 2 shows a side view thereof.

The water supply device of the illustrated bathroom is a shower (not shown) connected to the flexible pipe 200 upward and the water discharged downward 300 and the faucet valves 400 and 500 of cold and hot water. In the general form configured, it is shown in a state in which the electric instant water heater is installed with some modification to show the configuration and operation of the electric instant water heater according to the present invention.

As shown, the electric instant water heater according to the present invention functions as a movement path for accommodating water introduced from the water pipe into the housing 100 forming the exterior and discharging the introduced water to the shower or the water supply 300. The cold water pipe 10 and the hot water pipe 20 to perform the configuration is configured to be provided separately.

The cold water pipe 10 and the hot water pipe 20 are respectively connected to the cold water and hot water moving pipes associated with a boiler or a water supply facility to allow water to flow therein.

The water flowing into the cold water pipe 10 through the cold water moving pipe is discharged to the upper shower or downward water 300 according to the opening of the cold water faucet valve 400, and the hot water pipe 20 through the hot water moving pipe. The water flowing into is heated by the heating means as necessary to be discharged to hot water.

Therefore, the present invention is characterized by the configuration of the hot water pipe 20 to effectively heat the incoming water to shorten the discharge time of hot water and increase the energy efficiency.

According to the present invention, the hot water pipe 20 is located inside the housing 100 after securing a maximum internal space by positioning the cold water pipe 10 to the side without forming a separate reservoir inside the housing 100. It is configured to form a way to reciprocate in the left and right zigzag from the lower side of the housing 100 connected to the hot water moving tube to have a maximum path exited to the upper portion of the housing 100, the housing (as shown in the side view of FIG. The curved portion of the hot water pipe 20 toward the top of the 100 is formed to be bent in the form of a slope having a predetermined slope is configured to extend as possible inside the limited housing 100 space.

At this time, the inside of the hot water pipe 20 is provided to have the maximum path in the inner space of the housing 100 as described above to include an electric heating element 30 for generating high temperature heat by the application of power.

The electric heating element 30 is formed inside the hot water pipe 20 to be bent in the same shape, spaced apart so as not to contact the inner surface of the hot water pipe 20, and located at the center, both ends of the electrical connection terminal ( 31) is provided to allow electricity to flow into the electric heating element (30).

Therefore, the water flowing into the hot water pipe 20 is not limited to the movement through the inner circumference of the electric heating element 30 and the hot water pipe 20, the electric heating element 30 is heated to a high temperature by the application of electricity The hot water is generated by heating the introduced water.

As shown in the present invention, a reservoir is provided, and a heating element located at one side of the reservoir is heated into the housing 100 in comparison with the conventional instantaneous water heater to heat the entire water by convection of heat by heating the adjacent water. By inserting the electric heating element 30 having the same shape and length into the hot water pipe 20, which is the storage and movement path of the water, it is characterized in that it is configured to heat the introduced water as a whole.

In addition, the contact heat transfer area between the water and the electric heating element 30 introduced through the above configuration is distributed as wide as possible to significantly shorten the heating time for discharging hot water.

At this time, the electric heating element 30 is preferably configured to be able to supply clean hot water with a material that does not have the risk of oxidation and cracking because it is configured to transfer heat in direct contact with the water.

In addition, the control box 60 for controlling the power and components of the electric water heater is installed on one side of the housing 100, the temperature sensor 40 for measuring the temperature of the water flowing into the inlet side of the hot water pipe (20). ), And a pressure sensor 50 for measuring the weight of the water introduced into the hot water pipe 20 and a shutoff valve 70 for preventing the water introduced into the hot water pipe 20 from moving in the opposite direction of the outlet port. It is provided.

Typically, the water supply device installed in the bathroom is provided with a separate hot water pipe associated with the boiler, in the embodiment of the present invention so that the hot water pipe through the hot water pipe and the hot water pipe 20 of the instantaneous water heater is connected, the hot water On the outlet side of the pipe 20, the hot water is discharged to the outside through the shower and the tap water 300 by the opening of the hot water faucet valve 500, or the circulation outlet 21 to allow the hot water to flow back into the hot water pipe circulating (21) ) Is provided.

In the state where the boiler is already operating for the purpose of heating or hot water, the water flowing into the hot water pipe 20 inside the housing 100 through the hot water pipe is sufficiently heated so that the instantaneous water heater is operated to the electric heating element 30. There is no need to apply power.

Therefore, the temperature sensor 40 provided at the inlet side of the hot water pipe 20 measures the temperature of the incoming water so as to determine whether the electric heating element 30 is operating, and the control box 60 sets a predetermined reference value. By comparing the temperature and the temperature value measured by the temperature sensor 40 it is possible to determine and control the operation of the electric heating element (30).

In an embodiment of the present invention, the electric heating element 30 flows only when the temperature of the inflow water measured by the temperature sensor 40 is 30 ° C. or lower, so that the hot water pipe (even if the power of the instantaneous water heater) is in the ON state. If the temperature of the water flowing into the 20) exceeds 30 ℃ can cut off the electricity to the electric heating element 30 can prevent unnecessary power consumption.

In addition, the pressure sensor 50 is a device for determining the operation of the electric heating element 30, like the temperature sensor 40, the control by measuring the amount of water flowing into the hot water pipe 20 by weight In the box 60, the electric heating element 30 may be controlled in comparison with a predetermined reference value.

That is, when power is applied to the electric heating element 30 in a state in which there is no water introduced into the hot water pipe 20, the electric heating element 30 generates heat at a high temperature. Since there is no water to be heated, unnecessary power is not only wasted, but there is a problem that causes risks such as damage and explosion of the electric heating element 30.

Therefore, the pressure sensor 50 is to receive the pressure from the water introduced into the hot water pipe 20 in the inlet side of the hot water pipe 20 located in the lower portion of the housing 100 to measure the weight, the present invention In the embodiment, only when the measured data value becomes more than 0.5kg, electricity flows through the electric heating element 30 to generate heat and heat the introduced water.

The shutoff valve 70 located at the rear of the temperature sensor 40 does not interfere with the movement of water introduced into the water from the inlet side of the hot water pipe 20, but the inflow of the water is again inlet of the hot water pipe 20. It is configured to prevent the reverse movement to the side.

That is, when the use of hot water is stopped while water is introduced into the hot water pipe 20, the water left inside the hot water pipe 20 flows back to the inlet side of the hot water pipe 20 due to the action of gravity. The force to be generated is generated so that the shutoff valve 70 blocks the flow of water.

The control box 60 allows to arbitrarily manipulate the reference temperature and inflow amount of the inflow water for controlling the electric heating element 30, and receives the data measured by the temperature sensor 40 and the pressure sensor 50 It is configured to automatically control the operation and operating time, etc. of the electric heating element 30, and the electric coupling relationship and principle thereof is omitted because it can be sufficiently implemented by known techniques.
