In particular, it relates to an instantaneous hot water type electric boiler for heating by heating the hot water introduced from the outside.

In general, electric boilers are mainly used in homes, factories, or farms for concentrated livestock. In particular, electric boilers used in factories and farms are classified as industrial and manufactured in large capacity, and mainly heat the stored water by using low-cost late night electricity.

Since these electric boilers are manufactured in small capacity when used at home, they do not consume much power. However, since electric boilers used in buildings such as factories, farms, or buildings are manufactured at a large capacity, a large amount of power is required to heat a large amount of water. Accordingly, the applicant of the present invention has filed an electric boiler as shown in FIG. 1 to the Korean Intellectual Property Office and registered as of August 21, 2007 (Patent Registration No. 751485).

Then, the hot water supply pipe 70 guides the hot water heated in the lower chamber 62 to the upper portion U of the reservoir 50. At this time, the upper chamber 80 connected to the hot water supply pipe 70 collects the hot water supplied from the hot water supply pipe 70 and diffuses it to the upper portion U of the reservoir 50 through the discharge hole 80a. Accordingly, the reservoir 50 has hot water in the upper portion (U). Therefore, the reservoir 50 supplies the hot water of the upper portion U through the heating drain pipe 54 when the heating pump not shown connected to the heating drain pipe 54 is operated. Of course, the heating drain pipe 54 supplies the hot water to the heating pipe not shown so that the room is heated.

The electric boiler according to the related art does not heat exchange with the water of the water tank 50 in the hot water heater 60 at high temperature, but directly to the heating drain pipe 54 through the hot water supply pipe 70 and the upper chamber 80. Discharged. Therefore, there is an advantage that the hot water can be used directly for heating.

In addition, since the upper chamber 80 heats the low temperature water present in the upper portion of the water storage tank 50 using the high temperature water, there is an advantage in that the water of the water storage tank 50 can be heated in a short time.

However, the applicant of the present invention has applied for the present patent because the registered prior art electric boiler is improved more efficiently and conveniently.

On the other hand, reference numeral 52 in the drawing is a water supply pipe for supplying water to the reservoir 50, reference numeral 90 is a circulation member consisting of the bypass pipe 92 and the circulation pump 94.

The present invention is to provide an electric boiler that can quickly supply the hot water instantaneously rapid heating from the hot water heater to the heating pipe while ensuring a flow rate corresponding to the pumping pressure of the heating pump when the heating pump is operated for indoor heating. This is the purpose. In particular, the low temperature water at the bottom of the reservoir is processed into high temperature water and supplied to the upper side of the reservoir, and the flow rate of the discharge water corresponding to the pumping pressure of the heating pump can be secured by using the high temperature water at the upper side of the reservoir. The purpose is to provide an electric boiler of the present invention.

The present invention, while being in communication with the hot water heater is provided integrally with the hot water heater, allowing the water of the reservoir to flow into the inlet of the hot water heater, and the hot water heater as it is formed in a structure that prevents the flow back It is necessary to further comprise a; backflow inhibiting member for suppressing the water back to the inlet by the temperature difference is heated in isolation.

Here, the above-mentioned backflow inhibiting member is, for example, integrally installed in the hot water heater to shield the inlet, and a suction hole is formed in communication with the inlet to form a substantially orthogonal state on one side, the water stored in the reservoir It may be configured as a suction chamber for sucking into the suction hole and supply to the inlet.

On the contrary, the countercurrent suppression member is inserted into the hot water heater, for example, with both ends exposed, and suction holes are formed at the exposed both ends to suck water from the reservoir, and sucked into the suction holes while being substantially orthogonal to the suction holes.

In addition, since the backflow inhibiting member prevents backflow of the water isolated from the hot water heater, there is also an effect of preventing the heat loss during the backflow of the hot water rapidly heated in the hot water heater.

In addition, when the collection chamber is provided between the hot water supply pipe and the discharge pipe, there is an effect of heating the water stored in the upper portion of the reservoir using the hot water supplied from the hot water supply pipe.

In addition, when providing a hot water processing member in the bathroom there is an effect that can provide hot water for the bathroom separately from the heating water by using the heat of the hot water heater.

Hereinafter, an electric boiler according to the present invention will be described with reference to the accompanying drawings. FIG. 2 is a longitudinal sectional view of the electric boiler according to an embodiment of the present invention.

As shown, the electric boiler according to an embodiment of the present invention is a reservoir (110); Hot water heater 120; Hot water supply pipe 130; Discharge tube 140; And effluent replenishment means. The following describes these components in more detail.

First, the above-described reservoir 110 stores water supplied from the outside. The reservoir 110 is sealed in all directions as shown, the water supply pipe 112 is supplied with external water on one side. That is, the reservoir 110 stores water through the water supply pipe 112 on one side. At this time, the water supply pipe 112 is preferably provided in the lower portion of the reservoir 110 as shown.

Next, the above-mentioned hot water heater 120 isolates a part of the water stored in the reservoir 110 and rapidly heats it to a high temperature by using electricity supplied from the outside. The hot water heater 120 includes, for example, an isolation chamber 122 as shown; Electrothermal heater 124; can be configured to include.

Here, the above-described isolation chamber 122 is integrally embedded in the lower portion of the reservoir 110 as shown, through the inlet (122a) formed on one side of the water stored in the lower portion of the reservoir 110 Enter and isolate. Then, a part of the water isolated through the hot water supply pipe 130 which is integrally connected to the other side is supplied to the upper portion of the reservoir 110. That is, the isolation chamber 122 isolates the water flowing into the inlet 122a, and when the isolated water is heated by the heat transfer heater 124 which will be described later, the water tank 110 of the reservoir 110 will be described. Transfer it to the top. In this case, the inlet 122a described above is formed at any one of the lower side and the side of the isolation chamber 122 so that the low temperature water stored in the reservoir 110 is easily introduced. That is, the inlet 122a introduces the low temperature water present in the lower portion of the reservoir 110 into the isolation chamber 122 by the convection phenomenon according to the temperature difference. As the inlet 122a is formed in the lower portion or the side of the isolation chamber 122, the low temperature water, that is, the lower temperature, of the lower temperature is introduced into the isolation chamber 122. This inlet 122a is preferably formed in the lower portion of the isolation chamber 122, as shown in the lowest position in the isolation chamber 122.

The heat transfer heater 124 described above heats the water isolated in the isolation chamber 122 to a high temperature while being generated in the isolation chamber 122 and generating heat by electricity supplied from the outside. The heat transfer heater 124 may be configured as a plurality, as shown, alternatively may be configured in a singular.

Since the heat transfer heater 124 generates heat in a state of being embedded in the isolation chamber 122, it rapidly heats the water isolated in the isolation chamber 122. That is, the heat transfer heater 124 heats only the water isolated in the isolation chamber 122 to a high temperature. Of course, the water isolated in the isolation chamber 122 is rapidly heated by the heat transfer heater 124 as it is isolated from the water outside the isolation chamber 122.

Subsequently, the above-described hot water supply pipe 130 is a pipe directly connected to the hot water heater 120 as shown. Thus, the hot water supply pipe 130 guides the hot water rapidly heated in the hot water heater 120 to the upper portion of the reservoir 110, and supplies the hot water to the upper side of the reservoir 110. That is, the hot water heated to a high temperature in the isolation chamber 122 of the hot water heater 120 moves upward along the hot water supply pipe 130.

At this time, the hot water moves upward by the temperature difference. That is, since the high temperature hot water supplied to the hot water supply pipe 130 is lower than the temperature of the high temperature water of the rapid heating of the reservoir 110. In order to exchange heat due to the temperature difference, it naturally moves upward through the hot water supply pipe 130.

Here, the above-described hot water supply pipe 130 may be configured in plural as shown, alternatively may be configured in the singular. The hot water supply pipe 130 is preferably configured in plural as shown, so that a large amount of hot water moves to the top in a short time.

Subsequently, the discharge pipe 140 described above discharges the hot water supplied from the hot water supply pipe 130 to the outside of the reservoir 110. That is, the discharge pipe 140 immediately discharges the hot water of the hot water supply pipe 130 to the outside of the reservoir 110.

At this time, the discharge pipe 140 discharges the hot water to the outside by the pumping pressure of the heating pump connected to the heating pipe not shown. Of course, the hot water discharged to the outside of the reservoir 110 is introduced into the heating pipe not shown, and after heating, is introduced into the reservoir 110 again through the lower side water supply pipe 112 of the reservoir 110. That is, the hot water is heated through the heating pipe, flows back into the reservoir 110, is rapidly heated, and then circulates again supplied to the heating pipe.

Here, the discharge pipe 140 described above is preferably formed at the end of the hot water supply pipe 130 as shown. The discharge pipe 140 is manufactured separately from the hot water supply pipe 130 as shown, can be configured to be integrally connected to the hot water supply pipe 130 through welding or screwing. Alternatively, the discharge pipe 140 may be configured as shown by bending the upper end after extending the end of the hot water supply pipe 130 long.

Finally, the above-described discharge water replenishing means supplies a portion of the water stored in the upper side of the reservoir 110 to the discharge pipe 140. In this way, the discharge water replenishing means to supply water to the discharge pipe 140, so that the flow rate corresponding to the pumping pressure of the heating pump not shown acting on the discharge pipe 140 is provided to the discharge pipe 140.

In more detail about this, the discharge pipe 140 should discharge the hot water of the hot water supply pipe 130 to the heating pipe not shown by the pumping of the heating pump not shown. However, since the discharge pipe 140 is supplied to the hot water supply pipe 130 only water isolated from the isolation chamber 122 of the hot water heater 120, the water supply pipe 130 does not receive the amount of water corresponding to the pumping amount of the heating pump. can not do it. Accordingly, the discharge water replenishing means supplies a portion of the water stored in the reservoir 110 to the discharge pipe 140 so that the discharge pipe 140 receives the water corresponding to the pumping amount of the heating pump and discharges the water. Therefore, the discharge pipe 140 discharges water sufficiently corresponding to the pumping amount of the heating pump.

Such discharge water replenishing means, for example, so that the hot water stored in the upper side of the reservoir 110 as shown in the discharge pipe 140 so that the flow rate corresponding to the pumping pressure of the heating pump is secured in the discharge pipe 140 It is configured to communicate with the interior of the reservoir 110 and the discharge pipe 140, the flow supplement port 162 for supplying the water stored in the reservoir 110 to the discharge pipe 140. That is, the flow rate supplement 162 supplies the water stored in the reservoir 110 to the discharge pipe 140 to provide a flow rate (flow rate corresponding to the pumping pressure of the heating pump) required for the discharge pipe 140.
In particular, the discharge water replenishing means is to provide a flow supplement 162 in the upper portion of the reservoir 110, as shown to supply the hot water stored in the upper side of the reservoir 110 to the discharge pipe 140. desirable. As the flow supplement 162 is provided in the upper side of the reservoir 110, the hot water collected in the upper side of the reservoir 110 is sucked and immediately supplied to the discharge pipe 140. Of course, since the hot water is collected at the inner upper portion of the reservoir 110 by the convection phenomenon according to the temperature difference, the hot water is sucked into the flow supplement 162 by the pumping pressure during the operation of the heating pump.
Here, the above-described flow filler 162 may be configured as a pipe of the pipe form connected to the communication state on one side of the discharge pipe 140 as shown. Alternatively, the flow filler 162 may be configured as a hole 164 as shown enlarged.

The flow filler 162 as such supplements the amount of water discharged from the drain pipe 140. Therefore, the discharge pipe 140 supplies a sufficient amount of water to the heating pipe not shown.

On the other hand, the electric boiler according to an embodiment of the present invention needs to further include a; bathroom hot water processing member for processing hot water for the bathroom separately from the hot water for heating discharged from the discharge pipe (140).

Such a bathroom hot water processing member is preferably configured to process the hot water for the bathroom substantially by the heat of the hot water heater (120). The bathroom hot water processing member may be configured to include, for example, a hot water coil 180 wound on the hot water supply pipe 130 to process hot water for bathroom by the temperature of the hot water supply pipe 130. That is, the hot water coil 180 heats the water inside by the heat of the hot water supply pipe 130 through which the hot water of the hot water heater 120 flows. Accordingly, the hot water coil 180 provides hot water of high temperature to a bathroom or a kitchen not shown.

The hot water coil 180 may be manufactured separately from the above-described hot water supply pipe 130 as shown in the figure, and may be wound in the hot water supply pipe 130. Alternatively, the hot water coil 180 may flow through the hot water supply pipe 130 or the discharge pipe 140. In order to supply hot water directly to the bathroom or kitchen, it may be directly connected to the hot water supply pipe 130 or the discharge pipe 140 in a different state than shown. That is, when the hot water coil 180 is wound on the hot water supply pipe 130, the cold water supplied from the outside may be heated by the heat of the hot water supply pipe 130. Alternatively, the hot water coil 180 may communicate with the hot water supply pipe 130 or the discharge pipe 140. If the hot water supply pipe 130 or the discharge pipe 140 may be immediately discharged hot water. However, the hot water coil 180 is preferably wound in the hot water supply pipe 130 as shown, so that the heating hot water is prevented from being discharged to the hot water for bathroom.

On the other hand, reference numeral 190 in the drawing is a circulation member consisting of the bypass pipe 192 and the circulation pump (194). The circulation member 190 bypasses the upper side water of the reservoir 110 to the bypass pipe 192 and supplies it to the lower portion of the reservoir 110. At this time, the circulation pump 194 pumps water flowing through the bypass pipe 192. Therefore, the water in the reservoir 110 is forcedly circulated by the circulation member 190.

In the electric boiler according to the embodiment of the present invention configured as described above, as the inlet 122a is formed at the lower portion or the side of the isolation chamber 122 constituting the hot water heater 120, the low temperature water of the lowest temperature is effectively separated from the isolation chamber ( It can be isolated from the 122 and the rapid heating to a high temperature through the heat transfer heater (124). The hot water heater 120 supplies the water of the rapid heating reservoir 110 to the discharge pipe 140 through the hot water supply pipe 130. Therefore, the discharge pipe 140 supplies the hot water to the heating pipe not shown to heat the room. At this time, the discharge water replenishing means consisting of the flow refill port 162 is to supply a portion of the water stored in the reservoir 110 directly to the discharge pipe 140 so that the hot water smoothly discharged to the discharge pipe 140. Therefore, the discharge pipe 140 smoothly discharges the hot water into the heating pipe. In particular, the discharge water replenishing means supplies the hot water collected in the upper portion of the reservoir 110 to the discharge pipe 140 when the flow rate supplement 162 is provided in the upper portion of the reservoir 110. Of course, the discharge pipe 140 is supplied with high temperature water rather than low temperature water through the flow filler 162 to improve the heating efficiency while discharging the high temperature water.

On the other hand, the hot water supply pipe 130 and the discharge pipe 140 heats the water stored in the upper portion of the reservoir 110 by using the hot water flowing through the inside. That is, the hot water supply pipe 130 and the discharge pipe 140 not only discharges the hot water into a heating pipe not shown as needed, but also heats the water stored in the reservoir 110 using its own high temperature.

On the other hand, the hot water coil 180 wound on the hot water supply pipe 130 is heated due to the heat of the hot water flowing through the hot water supply pipe 130. Thus, the hot water coil 180 supplies hot water to a bathroom or kitchen not shown.

On the other hand, Figure 3 attached is a longitudinal cross-sectional view of the electric boiler according to another embodiment of the present invention, the electric boiler according to another embodiment is the same as all the configuration of the electric boiler shown in FIG. As described above, the collection chamber 170 is installed at the upper end of the hot water supply pipe 130, which is different from the electric boiler shown in FIG. Accordingly, only these differences will be described with reference to the accompanying drawings.

As shown, the electric boiler according to another embodiment of the present invention collects the hot water supplied from the hot water supply pipe 130, the collection chamber 170 installed on the top of the hot water supply pipe 130. As shown in the collection chamber 170, the discharge side end of the hot water supply pipe 130 is connected to one side, and the inlet side end of the discharge pipe 140 is connected to the other side, the hot water supply pipe 130 from the upper portion of the reservoir 110 At the same time, the hot water is guided to the discharge pipe 140 by collecting and diffusing the hot water.

Thus, the reason for providing the collecting chamber 170 in the upper portion of the reservoir 110, the collecting chamber 170 diffuses the hot water supplied from the hot water supply pipe 130 to the upper portion of the reservoir 110, the reservoir 110 This is to allow the water stored in the upper portion of the to be indirectly heated by the heat provided from the collection chamber 170. That is, the water stored in the upper portion of the reservoir 110 is heated by the heat generated by the collection chamber 170. Thus, the water stored in the reservoir 110 is heated faster.

On the other hand, it is preferable that the flow rate supplement 162 of the discharge water replenishing means is provided in communication with one side of the collecting chamber 170 as shown. Therefore, when the hot water is discharged to the discharge pipe 140 by the heating pump (not shown), the flow filler 162 discharges a portion of the water stored in the upper portion of the reservoir 110 through the collection chamber 170. To supply.

On the other hand, Figure 4 is a longitudinal cross-sectional view showing a backflow inhibiting member installed in the hot water heater shown in Figs. When described with reference to the accompanying drawings, such a backflow inhibiting member.

As shown, the hot water heater 120 is isolated after the water in the reservoir 110 is introduced through the inlet 122a. However, when the isolated water is heated, the hot water heater 120 is discharged while the water heated by the temperature difference flows back through the inlet 122a. Therefore, the electric boiler according to the embodiment of the present invention needs to include a backflow inhibiting member.

The countercurrent suppression member is in communication with the hot water heater 120 while being integrally provided in the hot water heater 120 to allow the water of the reservoir 110 to be introduced into the inlet 122a of the hot water heater 120. As water is formed in a structure that prevents backflow, it is preferable to configure the water heated in isolation from the hot water heater 120 to reflux back to the inlet 122a due to a temperature difference. That is, the backflow inhibiting member allows water to flow into the hot water heater 120 and suppresses backflow.

Such a reverse flow inhibiting member is integrally installed in the isolation chamber 122 of the hot water heater 120, for example, to shield the inlet 122a and substantially perpendicular to the inlet 122a on one side. It may be configured as a suction chamber 126 is formed in communication with the suction hole (126a). The suction chamber 126 sucks the water stored in the reservoir 110 into the suction hole 126a and supplies it to the inlet 122a. That is, the water sucked into the suction hole 126a of the suction chamber 126 enters the inlet 122a while bending at a right angle.

Therefore, even if the water introduced into the isolation chamber 122 is discharged through the suction hole 126a at a right angle at the inlet 122a even when heated, reverse flow is virtually impossible. That is, the suction chamber 126 has a suction hole 126a perpendicular to the inlet 122a, and thus provides a step for substantially preventing backflow to the outside of the isolation chamber 122.

Here, the above-described suction hole 126a is sucked as shown in the enlarged view "A" in the drawing so as to more reliably suppress the water flowing back from the isolation chamber 122 to the outside of the suction chamber 126. It is preferable to form in the upper side of the chamber 126. However, the suction hole 126a may be formed in the lower side of the suction chamber 126 as shown by the broken line in the enlarged view "A". Of course, the suction hole 126a may be formed at both the upper side and the lower side of the suction chamber 126.

Unlike the above, the countercurrent suppression member is inserted, for example, with both ends exposed to the isolation chamber 122 of the water heater 120 as shown in an enlarged view "B" in the drawing, and the reservoir 110 is exposed at both ends thereof. A suction hole 128a is formed to suck water from the suction hole 128a. The suction hole 128a is substantially orthogonal to the suction hole 128a and supplies the water sucked into the suction hole 128a to the isolation chamber 122. It may be configured as a suction pipe 128 is formed. That is, the suction pipe 128 is embedded in the isolation chamber 122, and suction holes 128a and supply holes 128b are formed at both ends and the upper portions, respectively. Thus, the suction pipe 128 absorbs water into the suction hole 128a and supplies water to the isolation chamber 122 through the supply hole 128b. At this time, the water sucked into the suction hole (128a) is bent at a right angle and then supplied to the isolation chamber 122 through the supply hole (128b). Of course, the water supplied to the supply hole (128b) is to be discharged to the suction hole (128a) after bending in the reverse flow, it is not discharged smoothly, in fact the backflow is suppressed.

Here, the above-described suction hole 128a may be formed at both upper ends of the suction pipe 128 as shown in enlargement. Alternatively, the suction hole 128a may be formed at both lower ends of the suction pipe 128 as shown in enlarged dashed lines. have. In addition, the suction hole 128a may be formed by completely opening both ends of the suction pipe 128.

In conclusion, the water introduced into the suction chamber 126 or the suction pipe 128 does not easily go out again. Therefore, the water sequestered in the isolation chamber 122 is not discharged by the reverse flow.

Since the above embodiments are merely illustrative of preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
