That is, the water inlet start end of the inlet pipe 30 is connected to the water supply unit (cold water supply unit) not shown, and the water inlet end of the inlet pipe 30 is divided into the lower reservoir 14 by the diaphragm 20. ) Is placed. The water inflow end of the inflow pipe 30 is disposed at a position substantially adjacent to the bottom portion of the hot water pipe 50 constituting the lower reservoir 14. Since the lower end of the linear pipe part 34 constituting the inlet pipe 30 becomes the water inlet end, the lower reservoir 14 of the hot water tank 10 in which the lower end of the inlet pipe 30 is partitioned by the diaphragm 20. Take a built-in structure.

Thus, the raw water (ie, cold water to be made into hot water) entering the inlet pipe 30 passes through the upper reservoir 12 of the hot water tank 10 to the lower reservoir 14 below the diaphragm 20. Supplied. At this time, since the lower end portion (ie, the water inlet end) of the inflow pipe 30 is disposed close to the bottom portion of the hot water tank 10, the raw water is lower from the lower reservoir portion 14 to the lower reservoir portion 14. Is supplied.

On the other hand, the periphery of the diaphragm 20 which divides the internal reservoir of the hot water tank 10 into the lower reservoir 14 and the upper reservoir 12 is spaced apart from the inner circumferential surface of the hot tub 10 by a predetermined distance. A distribution hole 22 in which hot water rises from the lower reservoir 14 to the upper reservoir 12 is secured.

Of course, if the hot water tank 10 has a shape other than a circular bucket, and the plate 20 also has a corresponding shape, the outer circulation hole 24 between the periphery of the plate 20 and the inner circumferential surface of the hot water tank 10 is provided. Of course, the shape of) may also be a hole other than the annular hole.

In addition, a circumferential portion of the diaphragm 20 is further provided with a linear diaphragm 21 extending in the direction of at least the lower reservoir 14 among the lower reservoir 14 and the upper reservoir 12. Between the linear diaphragm 20 and the inner peripheral surface of the hot water tank 10, a distribution hole 22 (that is, the outer distribution hole 24) at a predetermined interval is secured.

By the linear diaphragm 21 of the periphery of the diaphragm 20, a distribution hole 22 between the diaphragm 20 and the inner circumferential surface of the hot water tank 10 may be formed as a band distribution hole having a wider upper and lower width. In the present invention, the linear diaphragm 21 may have a configuration in which the lower reservoir 14 and the upper reservoir 12 extend in two directions. In this case, the linear diaphragm 21 may be extended to twice the width of the top and bottom.

In the present invention includes a heater 40 provided in the hot water tank (10). The heater 40 is a heating source for heating the water entering the lower reservoir 14 of the hot water tank 10 to make hot water. The heater 40 is embedded in the lower reservoir 14 of the hot water tank 10 partitioned by the diaphragm 20. At this time, the heater 40 is composed of a coil-type heater, it is configured to increase the heat exchange surface area with the water (raw water) entering the lower reservoir 14 of the hot water tank (10). Of course, the heater 40 may be provided on the outer circumferential surface of the hot water tank 10 so as not to be embedded in the lower water storage portion 14 of the hot water tank 10 and disposed on the circumference of the lower water storage portion 14. In addition, the heater 40 may have a structure built in the bottom reservoir 14 of the hot water tank 10 and at the same time provided on the outer circumferential surface of the hot water tank 10. That is, the outer heater 40 is further provided on the outer circumferential surface of the hot water tank 10 to be provided at the circumference of the lower reservoir 14. At this time, the outer heater 40 is composed of a bend-type heater. The outer heater 40 may be configured as a bend-type heater formed in a predetermined width along the vertical direction of the hot water tank 10.

The upper reservoir 12 of the hot water tank 10 is provided with a hot water pipe (50). One end of the hot water pipe 50 is connected to the hot water pipe connection hole provided in the upper surface of the hot water tank 10, and the other end of the hot water pipe 50 is connected to a hot water cock (valve) not shown. One end of the hot water pipe 50 may be referred to as a hot water discharge start end and the other end of the hot water pipe 50 may be referred to as a hot water discharge end. The hot water discharge start of the hot water pipe 50 may be a lower end of the hot water tank 10. The hot water discharge terminal communicating with the water part 12 may have a structure connected to the hot water coke, not shown. In this case, the outer heater 40 may be fixed to the outer circumferential surface of the hot water tank 10 by fixing means such as a bracket and a bolt (not shown).

According to the present invention having the above-described configuration, the raw water (cold water for warming up with hot water) coming from the inlet pipe 30 is partitioned by the lower reservoir 14 of the lower portion partitioned by the diaphragm 20 inside the hot water tank 10. ) Is made into hot water (hot water) by the heat of the heater 40, the hot water made in the lower reservoir 14 is the upper side through the distribution hole 22 communicated to both sides of the diaphragm (20) The hot water is raised from the lower reservoir 14 through the outer circulation hole 24, which rises to the reservoir 12 and is secured between the circumference of the diaphragm 20 and the inner circumferential surface of the hot water tank 10. As it rises to (12), the upper reservoir portion 12 above the diaphragm 20 of the hot water tank 10 is filled with hot hot water.

On the other hand, hot water is filled in the upper reservoir 12 of the hot water tank 10 and at the same time, the lower reservoir 14 under the diaphragm 20 is also filled with hot hot water heated by the heater 40.

In this state, when the hot water coke of the cold and hot water heater is opened, the hot water is discharged through the hot water coke from the hot water filled in the upper reservoir 12 to use hot hot water, and at the same time, hot hot water is discharged from the lower reservoir 14. Continue to climb up and fill the upper reservoir 12 with the amount of hot water discharged from the upper reservoir 12, the hot reservoir from the lower reservoir 14 to the upper reservoir 12, the lower reservoir The amount of raw water (that is, cold water) that is raised from the upper reservoir portion 12 to the upper reservoir portion 12 at 14 is introduced from the bottom of the lower reservoir portion 14 through the inflow pipe 30, and the specific gravity of the hot water is higher than the specific gravity of the cold water. It is lower so that hot water rises in the relatively higher layer in the lower reservoir 14 and is supplied to the upper reservoir 12 above the diaphragm 20 and enters the lower layer in the lower reservoir 14. Cold water heater (4 Since the hot water circulation supply structure, which is warmed up by 0) and rises to the upper layer, is implemented, lukewarm water may be prevented even when hot water is continuously used by opening the hot water cock in the cold / hot water machine.

In other words, in the present invention, the internal reservoir portion of the hot water tank 10 is partitioned into the upper reservoir portion 12 and the lower reservoir portion 14 by the diaphragm 20, and the hot water continues in the upper reservoir portion 12 accordingly. Even if it is used, the hot water warmed up from the lower reservoir 14 continues to implement the structure in which the amount of hot water rises to the upper reservoir 12 as much as the user uses, so that the cold water is mixed with the hot water so rapidly Since it prevents the discharge, even if you continue to use hot water in the cold and hot water heater is not enough satisfactory temperature does not come out to prevent the lukewarm water coming out too low temperature. Without the diaphragm 20, the cold water entering the inlet pipe 30 is mixed with hot water heated to a hot temperature too quickly, so that warm water of a sufficient temperature is not properly supplied and lukewarm water is supplied. The internal reservoir of 10 is partitioned into an upper reservoir 12 and a lower reservoir 14 by a diaphragm 20 so that the lower reservoir 14 continues to quickly cool cold water with hot hot water and Since the hot water discharged from the reservoir 12 is filled with the upper reservoir 12, the cold water is continuously supplied, thereby preventing the lukewarm water from being supplied.

In other words, since the raw water (cold water) from the inlet pipe 30 quickly enters the lower reservoir 14 and is subsequently heated by the heater 40 to make hot water (hot water), the hot and cold water for hot water The continuous use of hot water through the cork prevents lukewarm water from being supplied and ensures that the hot water is hot enough.

After all, even if you continue to use hot water in the hot and cold water heaters by implementing a special structure that can be filled with the hot water in the inside to prevent the case that the hot water does not come out properly, it may cause inconvenience to the user In addition, it is effective to solve various problems such as claims coming in due to the lack of hot water from consumers.

In addition, according to the present invention, the lower reservoir 14 may be provided not only through the distribution hole 22 of the diaphragm 20 but also through the outer distribution hole 24 secured between the circumferential portion of the diaphragm 20 and the inner circumferential surface of the hot water tank 10. Since hot water rises from the upper reservoir 12 to the upper reservoir 12, it is possible to prevent a somewhat inconvenient case, such as hot water rises too late from the lower reservoir 14 during the use of hot water in the cold water heater. That is, the outer distribution hole 24 between the periphery of the diaphragm 20 and the inner circumferential surface of the hot water tank 10 has a meaning in that the supply amount of hot water can be adjusted so as not to decrease even when hot water is continuously used in the cold / hot water heater. I will be big.

In addition, a linear diaphragm 21 is provided at the circumference of the diaphragm 20, and the outer diaphragm hole between the circumferential portion of the diaphragm 20 and the inner circumferential surface of the hot water tank 10 is provided by the linear diaphragm 21. Since the band (hole) of (24) is formed to further increase the band distribution hole, and the hot water passes through the band distribution hole, the heat of the heater 40 is added, so that the lukewarm water when the hot water is continuously used It is possible to more reliably prevent the supply.

In addition, since the heater 40 is configured as a coil-type heater to further increase the contact area with the raw water, since the raw water entering the lower reservoir 14 of the hot water tank 10 more quickly to make hot water, the lower side In the reservoir 14, it is even more reliably prevented that cold water will go to the upper reservoir 12 to produce water that does not have a sufficiently satisfactory temperature (ie, lukewarm water).

In addition, when the outer heater 40 is further provided on the outer circumferential surface of the hot water tank 10, the hot water tank 10 by applying heat to the heater 40 and the outer heater 40 inside the hot water tank 10 in duplicate. Since the raw water is made of hot water as hot water in the lower reservoir 14 of), the speed of making cold raw water into hot hot water is at least doubled.

At this time, the outer heater 40 has a band heater structure that occupies a predetermined width up and down of the hot water tank 10, so that the heat is applied from the entire surface without a section where the heat is missing in place compared to the coil type heater Therefore, the efficiency of making hot hot water in the hot water tank 10 becomes higher, and furthermore, since the outer heater 40 is a band heater, the work of installing the outer heater 40 in close contact with the outer circumferential surface of the hot water tank 10 is also installed. It also has a more convenient effect.

On the other hand, in another embodiment of the present invention, a portion of the inlet pipe 30 is composed of a coiled pipe portion 36, the coiled pipe portion 36 is built in the bottom reservoir 14 of the hot water tank 10 Can be taken. In another embodiment of the present invention, the inlet pipe 30 includes a water supply connection pipe part, a linear pipe part 34 having an upper end connected to the water supply connection pipe part, and a coiled pipe part 36 having an upper end connected to the linear pipe part 34. It includes, the coil-shaped pipe 36 is embedded in the lower reservoir 14 of the hot water tank (10).

In another embodiment of the present invention, the raw water coming in from the inlet pipe 30 passes through the coil-shaped pipe part 36 and goes out for a long time, and in this process for the long time the raw water turns out and with the heat generated from the heater 40 Since the heat exchange efficiency is further increased between, the raw water is lowered from the lower reservoir 14 of the hot water tank 10 further increases the efficiency of forming hot water, the hot water heated by this high heat exchange efficiency is the upper reservoir ( 12), so that lukewarm water is discharged from the cold and hot water heater is reliably blocked. By continually using hot water in the hot and cold water heater, it is possible to reliably block the case of lukewarm water coming out on the way, thereby making it possible to reliably prevent a case of causing inconvenience to the hot or cold water user or a claim from the user. That is, when the raw water is returned to the coiled pipe portion 36 of the inlet pipe 30, the time for the raw water to be warmed for a sufficient time is generated, and the hot water for this sufficient time to ensure that the hot water is supplied to ensure You can do that.

At this time, the lower reservoir 14 has a heater 40 is built in the inner region of the coiled pipe portion 36 of the inlet pipe 30, the heater 40 is configured as a coil heater. In this case, the raw water stays for a sufficiently long time through the coiled pipe part 36 and then turns out, and in this process, the coiled heater heats the raw water one after another, thereby further accelerating the speed of making cold raw water into hot hot water.

In addition, in another embodiment of the present invention, the diaphragm 20 is embedded in the water reservoir inside the hot water tank 10 so as to be able to move up and down. The diaphragm 20 is provided with a pipe coupling hole 24 communicates with both sides, the inlet pipe 30 is a linear pipe portion 34 that extends up and down to enter the internal reservoir of the hot water tank 10, and And a coiled pipe part 36 connected to the linear pipe part 34, and the pipe coupling hole 24 is slidably coupled to the linear pipe part 34, so that the lower reservoir part partitioned by the diaphragm 20 ( The coiled pipe part 36 is disposed at 14, and the diaphragm 20 is moved up and down along the linear pipe part 34 so that the volume of the upper reservoir 12 and the lower reservoir 14 is variable. .

In other words, when the raw water (cold water) enters the lower reservoir below the diaphragm 20 and hot water falls out of the upper reservoir 12, the diaphragm 20 rises and water stops entering the lower reservoir. When the hot water is passed through the lower reservoir through the distribution hole 22 communicating the lower reservoir and the upper reservoir, the diaphragm 20 is lowered toward the bottom of the hot tub 10 by its own weight. As the diaphragm 20 moves up and down in the internal reservoir of the hot water tank 10, the volume of the upper reservoir 12 and the lower reservoir 14 is changed based on the diaphragm 20.

According to another embodiment of the present invention, as hot water is used in the cold / hot water machine, hot water is drained from the upper reservoir 12, and the lower reservoir 14 is filled with raw water, and the diaphragm 20 is in this process. As it rises, the volume of the lower reservoir 14 becomes larger than the volume of the upper reservoir 12. The cold water coming from the lower portion of the lower reservoir 14 is heated by the heater 40 to be hot hot water. And hot water is lower than the specific gravity of the cold water so that the hot water rises to the upper reservoir in the lower reservoir 14, and the cold water is circulated downward in the lower reservoir 14. Hot water is produced by.

At this time, since the hot hot water further upward from the lower reservoir 14 is supplied to the upper reservoir 12, and the hot hot water is further filled up from the lower reservoir 14, the hot water is turned on without the hitch. It can be supplied through the receiving coke, and when hot water is no longer used in the cold and hot water heater, the outer distribution hole between the distribution hole 22 of the diaphragm 20 itself and the periphery of the diaphragm 20 and the inner circumferential surface of the hot water tank 10. Through 24, hot water from the lower reservoir 14 rises to the upper reservoir 12, and the diaphragm 20 is lowered again at the position raised by its own weight.

In another embodiment of the present invention, as the hot water continues to be used, hot water is supplied from the upper reservoir 12 of the hot water tank 10 and at the same time the diaphragm 20 is raised while the lower reservoir under the diaphragm 20 is raised. Since the volume of the water portion 14 is further increased so that the lower reservoir 14 is filled with more hot water, it is most reliably prevented when lukewarm water is supplied on the way while continuously using hot water in the cold / hot water heater. As the diaphragm 20 rises, the volume of the lower reservoir 14 of the hot water tank 10 increases by that much. The hot hot water produced in the lower reservoir 14 is lower in the lower reservoir 14 due to the difference in specific gravity. In the upper part of the reservoir, the cold water goes up to the lower part of the reservoir, which makes the hot water faster than when the diaphragm 20 is fixed. The most efficient in the function to supply hot water stably without interruption. In other words, when the diaphragm 20 rises due to continued use of hot hot water, the diaphragm 20 more clearly distinguishes the hot hot water layer and the cold raw water layer, and stops using the hot hot water when the diaphragm 20 stops using the hot water. This is going down, another embodiment of the present invention is best in the function to use the hot water as much as possible.

In this case, the upper linear diaphragm 21 and the lower linear diaphragm 21 extending up and down from the circumference of the diaphragm 20 are provided when the pipe coupling hole 24 of the diaphragm 20 is biased to one side from the center. Since the diaphragm 20 is prevented from tilting while being raised and lowered, it is more stable in the elevating operation of the diaphragm 20, and the upper linear diaphragm 21 and the lower linear diaphragm 21 have ends of the hot water tank 10, respectively. Since the upper portion and the bottom portion of the contact portion can act as a stopper, the volume of the upper reservoir portion 12 and the lower reservoir portion 14 relative to the diaphragm 20 can be maintained at an appropriate level at all times.

On the other hand, the diaphragm 20 is more preferably made of a convex downward plate shape. The inner reservoir of the hot water tank 10 is partitioned into a lower reservoir 14 where water is heated by the diaphragm 20 and an upper reservoir 12 where hot hot water comes up. If convex can increase the space of the upper reservoir portion 12 that can hold the hot water as much, it is more helpful to prevent the case that hot hot water does not come out properly during the use of cold and hot water.

In addition, the linear pipe part 34 of the inlet pipe 30 is provided with an upper stopper 34US and a lower stopper LS, and the upper stopper (when the diaphragm 20 rises up from the inside of the hot water tank 10). The upper surface of the diaphragm 20 is caught by 34US), thereby preventing the diaphragm 20 from excessively rising upward, and the lower stopper 34LS when the diaphragm 20 descends from the inside of the hot water tank 10. Since the bottom of the diaphragm 20 is caught, it can prevent that the diaphragm 20 falls down excessively.

Industrial Applicability The present invention has industrial applicability as a complex hot water tank structure for a drinking water machine which can prevent a case where hot water does not come out properly on the way even if hot water continues to be used in a cold and hot water machine.
