Description

{Warm water supply heat exchanger}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water direct heating medium, and more particularly, to a new hot water direct heating medium which is designed to prevent the heater from being damaged by heat,

A hot water supply device which has a tendency to pursue miniaturization and weight reduction of a product which is frequently used in recent years and uses a water storage tank having a relatively low thermal capacity and a relatively small capacity and inserts a heater therein to instantaneously heat the hot water supply device is used . On the other hand, there has been developed a hot water heating device in which a heater used in a hot water supply device is submerged in a water storage tank and heated. At this time, the cylindrical metal or ceramic heater is used as a small-sized and thin type instantaneous hot water heater, and the heat exchange efficiency is excellent. However, since the manufacturing process is complicated and the manufacturing cost is high, the production cost is relatively increased. Further, there is a disadvantage in various manufacturing and use methods such as breakage of the ceramic base material or the like instantly when the heater is energized due to thermal impact or uneven application of the heat generating resistor and local heating phenomenon. In particular, since the heater is continuously turned on in order to continuously heat the water filled in the water tank, there is a problem that electric power is wasted. Even when hot water is not used, the heater will continue to operate, which is a waste of electricity. In addition, there is a problem that various noxious bacteria propagate in the water tank in the past and are harmful to the human body. There is a problem which is harmful to the human body of the hot water user because the hot water in which bacteria propagate is supplied as it is to a hot water heater or the like. The conventional hot water method is basically a water tank filled with water and a heater heated by iron in the middle of the water tank. The water is filled all the time, so there is a possibility that the bacteria can multiply when the water is continuously used. Because the water in the bucket must be kept warm with hot water, even when not in use, electricity is continuously being used and heating.

Referring to the drawings, the hot water direct heating medium according to the present invention includes a heat exchanging chamber HC formed between the heater 10 and the outer tube 20 by coupling the outer tube 20 to the outer peripheral surface of the heater 10, The outer tube (20) is provided with an inlet (24) and an outlet (26). The quartz tube 12 is formed as a double tube and the inner tube quartz tube 12 is formed with a heating medium of the heating means and the outer tube quartz tube 12 ) Is a method in which cold water is passed and hot water is directly discharged. The inner tube means the tube 12 of the heater 10 and the heating means means the heater 10 and the outer tube means the outer tube 20.

The heater (10) has a structure in which a heat generating coil (14) is embedded in a tube (12). In the present invention, the tube 12 is made of quartz. That is, the tube 12 of the heater 10 is formed of a quartz tube. The heat generating coil 14 provided inside the tube 12 of the heater 10 generates heat by power supply. The lead wire 16 is connected to the heat generating coil 14 through the conductive tube 17 and the power supply wire is connected to the lead wire 16 so that the heat generating coil 14 is heated by the power supply through the electric wire, . In the present invention, the heater 10 may be employed as a halogen heater in which a heating coil is embedded in a quartz tube. Further, in the present invention, the heater 10 may have a bar-shaped heater structure having a circular section.

The outer tube 20 is coupled to the outer circumferential surface of the heater 10. A heat exchange chamber HC is secured between the inner peripheral surface of the outer tube 20 and the outer peripheral surface of the tube 12 of the heater 10. [ The material of the outer tube 20 is quartz. That is, the outer body 20 is also made of a quartz tube. The outer tube 20 is bonded to the outer peripheral surface of the quartz tube of the heater 10 by the bonding portion BP. At this time, the joining portion BP for joining the outer body 20 to the quartz tube of the heater 10 is a contact portion between the outer body 20 and the heater 10, that is, the contact portion between the outer body 20 and the heater 10 Can be formed by heating with a heating device HD such as a heating torch or the like. That is, the joining part BP is formed by heating and melting a portion of the quartz outer body 20 contacting the quartz tube of the heater 10, and then hardening the melted part, The outer tube 20 and the quartz tube of the heater 10 are bonded to each other. Then, a heat exchange chamber HC having a constant width is secured between the outer circumferential surface of the quartz tube of the heater 10 and the inner circumferential surface of the outer tube 20. On the other hand, the bonding portion BP may be formed by melting and curing the quartz solvent WB at the contact portion between the outer body 20 and the quartz tube of the heater 10. 4, the bar-shaped quartz solvent WB is melted by a heating device HD such as a welding torch to melt the bonding portion BP between the outer body 20 and the quartz tube of the heater 10, The bonding portion BP is formed and the quartz tube of the heater 10 is bonded to the bonding portion BP through the bonding portion BP when the fused bonding portion BP is cured. As shown in FIG. The bonding of the outer body 20 with the quartz tube of the heater 10 by melting the solvent WB is one of bonding methods between the outer body 20 and the heater 10. At this time, the inward flange portion 22 extending to the central portion of the outer tube 20 is provided at both ends of the outer tube body 20 so that the inward flange portion 22 is connected to the outer peripheral surface of the quartz tube of the heater 10 As shown in Fig. It can be said that the width of the heat exchange chamber HC is secured by the width of the inward flange portion 22.

The inlet 24 is adjacent to the upper end of one side of the outer body 20 and the outlet 26 is adjacent to the lower side of the other side of the outer body 20. The inlet port 24 and the outlet port 26 are connected to each other by a cross port CP connected in the direction crossing the longitudinal direction of the outer body 20 and a cross port CP connected to the cross port CP, And a parallel port (NP) portion extending in a direction parallel to the first direction. When viewed from the front of the outer body 20, the inlet 24 is provided at the upper left and the outlet 26 is provided at the lower right. The parallel port NP of the inlet 24 extends toward the upper end of the outer tube 20 and the parallel port NP of the outlet 26 extends toward the lower end of the outer tube 20. The direct water flowing through the inlet 24 passes through the heat exchange chamber HC secured between the heater 10 and the outer body 20 without passing through the outlet 26 and then flows out to the outlet 26 have. The inlet 24 is connected to a direct water supply via a connection tube such as a hose and the outlet 26 is connected to a hot water application by a connection tube such as a hose. The term " straight " means water not heated by the heater 10. The inlet 24 is connected to a direct water supply, not to a water tank for storing direct water. That is, the direct water enters directly from the direct water supply source through the inlet 24.

According to the present invention having the above-described structure, after the direct water enters through the inlet 24 provided in the outer body 20, the water is directly passed through the heat exchange chamber HC secured between the outer body 20 and the heater 10. [ The hot water generated by the heat exchange with the heater 10 in the heat exchange chamber HC is discharged to the outside through the outlet 26 (For example, a hot water mat, a hot water heater, etc.). At this time, in the present invention, since the heater 10 uses the halogen heater 10 different from the general heater 10, the direct water is heated to a considerably high temperature, so that the direct water is heated very rapidly, do.

The effect of the hot water direct heating medium according to the present invention is as follows.

First, when the hot water is not used, the heater 10 is operated only when the operation of the heater 10 is stopped and the hot water is used, and the hot water can be rapidly heated to the hot water to quickly supply the hot water. . That is, when the hot water is not used, it is not necessary to operate the heater 10, and the heater 10 is operated whenever hot water is required, so that the heater 10 must be always turned on so that the water contained in the water reservoir is always heated Electricity waste can be reduced considerably. Assuming that a conventional water heater consumes 100% of electricity, the present invention uses only about 30% electricity compared to the conventional one, so that the energy saving effect is significant.

Secondly, when the direct water is used without using the hot water, the operation of the heater 10 is stopped, so that the direct water can be supplied in time. If hot water is needed, hot water can be supplied in a timely manner, and if direct water is needed, direct water can be supplied in time. You can use hot water only as much as you need, and you can use hot water as much as you need.

Third, it is not necessary to construct a storage tank for storing direct water or hot water. The structure of the hot water heater is simplified as the construction of the storage tank is not required, and the structure of the hot water heater or the like is simplified, which is advantageous in terms of cost.

Fourth, the far infrared rays generated in the quartz, that is, the far infrared rays generated in the quartz tube of the heater 10 and the quartz outer body 20 remove harmful substances such as bacteria and bacteria, so that fresh and clean hot water can be used . That is, when the quartz tube 12 is used as the material, the far-infrared ray wavelength is diverged when heat is dissipated, so that the generation of bacteria can be suppressed and the cleanliness can be maintained. It is hygienically very advantageous.

Fifthly, since the outer tube 20 and the tube 12 of the heater 10 are formed of quartz tubes, the outer tube body 12 and the outer tube body 20 of the heater 10 can be easily separated from each other 20 or the tube 12 of the heater 10 is reliably prevented from being broken. Product reliability is very high.

Sixth, since the inlet 24 and the outlet 26 provided in the outer tube 20 are not a straight path but a curved path in a roughly Ni-Cd shape, the time for the direct water to stay in the heat exchange chamber HC is further increased , The heat exchange efficiency becomes higher. The inlet port 24 and the outlet port 26 are connected to each other by a cross port CP connected in the direction crossing the longitudinal direction of the outer body 20 and a cross port CP connected to the cross port CP, And the hot water coming into the inlet 24 enters the heat exchange chamber HC through the longer path and the hot water exiting the outlet 26 also passes through the longer path < RTI ID = 0.0 > The residence time of the direct water for heat exchange becomes longer, and the heat exchange efficiency becomes higher.

According to another embodiment of the present invention, the heater 10 is constructed such that a heat generating coil 14 is embedded in the tube 12. The tube 12 has a projection 30 on the outer circumferential surface thereof , The projecting portion 30 is disposed in the heat exchange chamber HC between the tube 12 of the heater 10 and the outer body 20. At this time, the projecting portion 30 extends spirally along the outer circumferential surface of the tube 12 of the heater 10. The tube 12 of the heater 10 may be composed of a quartz tube in the same manner as in the above-described embodiment. The quartz tube tube 12 has a spiral protruding portion 30 on its outer circumferential surface. The protruding portion 30 can be thermally bonded to the outer circumferential surface of the tube 12 of the heater 10. A bar type solvent WB of quartz is placed along the outer circumferential surface of the tube 12 of the heater 10 and the bar type quartz solvent WB is melted by a heating apparatus HD such as a welding torch, The molten quartz solvent WB forms the spiral molten ridge portion 30 and the molten ridge portion 30 is hardened and the molten quartz melt WB hardens to form the helical ridge portion 30 on the outer peripheral surface of the tube 12 of the heater 10 30 may be provided. The spiral protrusion 30 may be formed by melting the quartz bar type solvent WB by thermally bonding the protrusion 30 to the outer circumferential surface of the tube 12 of the heater 10. [ The protrusion 30 may be a closed loop type or may have a cylindrical protrusion of a predetermined length and be thermally bonded to the outer circumferential surface of the tube 12 of the heater 10. Of course, the tubular protrusion 30 may be made of a quartz material.

A space is formed between the protrusion 30 and the inner circumferential surface of the outer tube 20 at a predetermined distance. The space D1 is larger than the width of the protrusion 30. That is, the space between the protruding portion 30 provided on the outer circumferential surface of the tube 12 of the heater 10 and the inner circumferential surface of the outer tube 20 is secured by a predetermined width. The space is secured to such an extent that the protruding portion 30 can be prevented from pushing out the outer tube 20 outward. That is, when the heat generating coil 14 of the heater 10 generates heat and heat is generated, the protruding portion 30 also expands due to heat. When the protruding portion 30 is not thermally expanded, (Hereinafter, referred to as the space width at the time of unexpanded convex portion 30), and the width at the time of thermal expansion of the convex portion 30 30) expansion width). The space width D1 at the time of non-expansion of the protrusion 30 is larger than the expansion width of the protrusion 30. [ Therefore, even if the protruding portion 30 is thermally expanded, the clearance D2 is always ensured between the protruding portion 30 and the outer member 20.

In the case of another embodiment of the present invention, when the direct water enters through the inlet 24 and passes through the heat exchange chamber HC, the time required for the water to flow into the heat exchange chamber HC becomes longer by the rotation of the projection 30 , The heat exchange efficiency between the heater 10 and the direct water becomes higher and the heat exchange efficiency becomes higher means that the efficiency of supplying hot water is further increased. As the heat exchange efficiency is further increased, the operating time of the heater 10 can be further shortened, so that the electricity consumption can be further reduced.

In addition, the time required for the direct water to pass through the outer body 20, which is the quartz tube, and the tube 12 of the heater 10 is increased so much, and the sterilizing ability of the harmful bacteria by the far-infrared rays can be further improved.

Even after the protrusion 30 is inflated by the heat of the heater 10, the clearance D2 is always ensured between the protrusion 30 and the outer tube 20, It is possible to surely prevent the outer body 20 from being pressurized and broken by the thermally expanded protruding portion 30 without pushing the outer body 20 outward from the center portion. That is, in another embodiment of the present invention, the protruding portion 30 is constructed to prevent the outer body 20 from being broken by the thermally expanded protruding portion 30, while enhancing the heat exchange efficiency between the direct water and the heater 10 .

Meanwhile, in the case of the other embodiments of the present invention, since the effects of the above-described embodiment of the present invention are intact, duplicate descriptions thereof will be omitted.

It is to be understood, however, that the scope and spirit of the present invention is not limited to these specific embodiments, and that various modifications and changes may be made without departing from the spirit of the present invention. If you have, you will understand.
