Description

HOT WATER SUPPLY DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply device, and more particularly, to a hot water supply device for heating a fluid returned from a hot water mat or the like,

Recently, electric mats and hot water mats have been used for heating in homes and outdoors. In particular, there is a problem that an electric heating wire is directly wired to a mat to generate a large amount of electromagnetic waves. However, the hot water mat is a preferred method because the hot water hose is circulated in the mat instead of the electric heating wire, and there is no need to worry about the electromagnetic wave threat. In addition, the hot water mat is composed of a compact hot water supply device for portable and convenient use instead of a large type of boiler, and various fluids are used as a heat transfer medium and water is generally preferred.

The structure of the hot water supply device includes a storage tank in which water is stored, a heater installed in the storage tank for heating water in the storage tank, water recovered from the hot water mat, hot water heated by the heater, And a motor pump.

The heat of the heater can form temperature contour lines according to the distance from the heater, and the temperature contour lines can be changed to the same one contour line having the desired water outlet temperature according to the heating time of the heater.

However, since the heater needs to heat all the water in the storage tank, energy consumption is high and water in the storage tank must be heated for a long time in order for the water in the storage tank to have the same one contour line. In addition, since the water in the storage tank is heated for a long time, the storage tank frequently requires supplementary water from the outside due to the evaporation of water according to the heating time of the heater.

In addition, since the hot water supply device is one of the important issues of small size and light weight, there is a problem that the increase in the size of the entire components including the storage tank is a factor of lowering the competitiveness. In addition, as the hot water supply device is manufactured in a small size, there is no space between the components, so a structural design that is easy to assemble, disassemble and repair is required.

In addition, since the connection distance between the hot water supply device and the mat is short, the noise and vibration generated by the hot water supply device are directly transmitted to the user of the mat. Therefore, to be.

These various requirements are not independent of each other but are organically related issues. Therefore, there is a desperate need to optimize the design of the hot water supply system.

A related prior art is Korean Patent Registration No. 100783597 entitled Hot Water Heating Device for Hot Water Circulation Mat, Date of Registration: December 03, 2007).

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for controlling the temperature of an automobile by means of quick and uniform temperature control, inconvenience due to frequent replenishing of replenishing water, small size and light weight, easy assembly and repair, And to provide a hot water supply device that can solve the problem efficiently.

According to an aspect of the present invention, there is provided a hot water supply apparatus including: a storage tank having an inlet space and an inner space formed with a bottom surface outlet, the damper coupling portion being protruded downward from an outer surface of the storage tank; A heater cover installed inside the storage tank and forming an isolated flow path space including an inlet and a discharge port of the storage tank between the storage tank and the bottom surface of the storage tank and including an inlet from a storage tank; A heater installed in the isolated flow path space; A motor pump installed at an upper portion of the storage tank and having an inlet port connected to an outlet port of the storage tank; And a damper sealing between the inlet port of the motor pump and the outlet port of the storage tank.

At least one of an inner bottom surface of the storage tank and an inner surface of the heater cover may support the heater cover and protrude from the column to form a flow path around the heater.

The hot water supply device may further include an outflow temperature sensor provided adjacent to the outflow port side of the storage tank to measure the outflow temperature.

The heater cover may have a discharge pipe for discharging the bubbles present in the flow path space to the outside of the storage tank.

The discharge pipe may have a tubular structure which is located at an inlet of the motor pump and an outlet of the storage tank and extends to an upper end of the storage tank.

Wherein the heater is formed in a U-shape, the inlet of the storage tank is located at the end of the heater, and the outlet of the storage tank is located in a central region surrounded by the U-shaped heater, So as to be guided out of the central region of the heater.

Wherein the damper coupling portion of the storage tank is formed as a water pipe surrounding the entire periphery of the outlet port of the storage tank, and the upper surface of the motor pump is connected to a water inlet pipe Can be formed to protrude upward.

The damper includes a pipe-type storage tank coupling portion having a ring-shaped groove having a predetermined depth to be inserted into the water-discharging pipe of the storage tank in the vertical direction, and a pipe- And an elastic body formed between the storage tank coupling portion and the motor pump coupling portion and having at least one corrugated connection portion.

The damper may include a first clamp ring for pressing the storage tank coupling portion of the elastic body to the water outlet pipe of the storage tank and a second clamp ring for pressing the motor pump coupling portion of the elastic body to the inlet pipe of the motor pump .

The second clamp ring may be a coil spring formed in a predetermined length in the vertical direction.

The connection portion of the elastic body may be connected to the upper end of the storage tank coupling portion and the upper end of the motor pump coupling portion, and a hooking protrusion may be formed on the lower portion of the motor pump coupling portion to prevent the downward separation of the second clamp ring. .

The elastic body may further include a flange portion that surrounds the upper end of the storage tank coupling portion and closely contacts the bottom surface of the storage tank.

The damper coupling portion of the storage tank is formed to be larger than the outlet port of the storage tank so as to form a space in which the connection portion of the damper is interposed between the damper coupling portion of the storage tank and the inlet pipe of the motor pump, May be formed to have a size corresponding to the outlet port and may be positioned adjacent to the outlet port of the storage tank.

Since only a small amount of water in the flow path space isolated by the heater cover can be circulated and heated, the load of the heater and the motor pump can be reduced to a minimum, and therefore, the overall size can be easily reduced. Since water can only be heated and circulated in a required amount of water, it is not necessary to frequently replenish water due to evaporation of water.

In addition, since the damper coupling portion of the storage tank is formed outside the storage tank and the layout of the entire components is dispersed, the present invention can be made compact, lightweight, and optimized without structural interference. It can be removed from the tank and easily repaired or replaced.

Further, according to the present invention, since the motor pump is designed to be installed on the lower side of the storage tank, the noise and vibration of the motor pump can be prevented from being directly transmitted to the side of the hot water mat. By the damper interposed between the storage tank and the motor pump Noise and vibration of the motor pump may be attenuated.

Further, since the damper and the outlet pipe of the storage tank are uniformly sealed between the damper and the storage tank and the inlet pipe of the damper and the motor pump are uniformly sealed over the entire circumference, Can be excellent.

Further, in the present invention, since the damper can be surrounded and protected by the water outlet pipe of the storage tank, damper damage by foreign matter or the like can be prevented.

In addition, since the damper is interposed between the inlet pipe of the motor pump and the outlet pipe of the storage tank, the damper damages due to the high temperature Can be prevented and the life of the damper can be increased, so that the problem of frequent replacement of the damper can be prevented.

Further, according to the present invention, when the damper is replaced, the damper can be easily separated from the storage tank and the motor pump and reassembled from the outside of the storage tank without disassembling the storage tank and its internal components.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in order to avoid unnecessarily obscuring the subject matter of the present invention.

1 to 7, a hot water supply apparatus according to an embodiment of the present invention includes a storage tank 10, a heater cover 20, a heater 30, a motor pump 50, , And a damper (100).

The storage tank 10 has a predetermined volume of internal space for storing a heat transfer fluid (for example, water, etc., hereinafter, the heat transfer fluid is limited to 'water' for convenience of explanation) And a tank cover (not shown).

The bottom surface or the bottom surface of the storage tank 10 is connected to a heat-dissipating member (for example, a hot-water mat or the like; hereinafter, the heat-dissipating member is limited to a hot- At least one inlet 10a may be formed to receive the water.

The bottom surface of the storage tank 10 is connected to the outlet 10b of the storage tank 10 through which hot water heated by the heater 30 flows to the motor pump 50, Can be formed.

The inlet (10a) and the outlet (10b) of the storage tank (10) may be formed at positions that do not overlap with the heater (30) in the vertical direction. For example, when the heater 30 is U-shaped, the inlet 10a and the outlet 10b of the storage tank 10 may be located in the inner region surrounded by the U-shaped heater 30, It is also possible to form the inlet port so that the circulating water flows into the side surface of the storage tank instead of the bottom surface. Water flowing from the inlet 10a of the storage tank 10 to the outlet 10b of the storage tank 10 can smoothly flow along the outer circumferential surface of the heater 30. [ That is, the flow resistance due to the heater 30 can be reduced, and therefore the load on the motor pump 50 can be reduced.

The inlet (10a) and the outlet (10b) of the storage tank (10) may be arranged in a line along the longitudinal direction of the heater (30). Therefore, the water can be sufficiently heated while flowing from the inlet 10a of the storage tank 10 to the outlet 10b.

At least one column portion 10c may be formed on the inner bottom surface of the storage tank 10 so as to support the heater cover 20 in a vertical direction. The column 10c of the storage tank 10 may be located in the inner region surrounded by the U-shaped heater 30 so that the flow resistance does not increase, and water may move along the outer peripheral surface of the U- It can be a guide channel to make it. Therefore, the bottom area of the storage tank 10 can be optimally designed so as not to be unnecessarily increased compared to the hot water load.

The heater 30 is suitable for forming and heating the flow path, but is not limited thereto. The heater 30 may include a simple linear heater, a U-shaped heater close to a circular shape, and the like.

The damper engaging portion 10d of the storage tank 10 is formed on the bottom of the storage tank 10 so that the damper engaging portion 10d of the storage tank 10 is connected to the damper 100, And may be formed to protrude downward on the side surface. Therefore, the inside of the bottom surface of the storage tank 10 is structurally complicated due to the formation of the heater cover and the flow passage. The damper engagement portion 10d of the storage tank 10 is formed outside the storage tank 10 It is easy to design the inside of the storage tank 10 and the outside of the storage tank 10, and it is easy to assemble and disassemble. Furthermore, there is no need to worry about the flow resistance due to the damper engagement portion 10d of the storage tank 10. [

Particularly, the damper coupling portion 10d of the storage tank 10 may be formed as a water pipe surrounding the entire circumference of the water outlet 10b of the storage tank 10. Therefore, the damper coupling portion 10d of the storage tank 10 can be formed in a simple tubular shape, so that it can be structurally simplified. The damper engaging portion 10d of the storage tank 10 is connected to the inlet pipe 52 of the motor pump 50 so as to form a space in which the connecting portion 116 of the damper 100 is interposed, The damper 100 may be formed to be larger than the outlet port 10b of the tank 10 to protect the damper 100. [

On the other hand, an outflow temperature sensor 40 may be installed on the bottom surface of the storage tank 10 to measure the outflow temperature at the outflow port 10b of the storage tank 10 in the up and down direction.

Since the outflow temperature sensor 40 is provided adjacent to the outlet 10b, it is possible to quickly measure the overheating of the outflow temperature when the circulation is stopped in the heat exhausting member, for example, Overheating and abnormalities can be detected and actions can be taken accordingly.

 Also, three water level sensors may be installed in the upper part of the storage tank 10 so that low, middle, and high water levels of the storage tank 10 can be measured, respectively.

The heater cover 20 is disposed between the bottom surface of the storage tank 10 and the bottom surface of the storage tank 10 so as to form an isolated flow path space including the inlet port 10a and the outlet port 10b of the storage tank 10. [ And is installed inside the storage tank (10). Therefore, not only the water in the storage tank 10 is circulated but the water can be circulated along the flow path only in the isolated space, so that the load of the motor pump 50 and the heater 30 is small, ) And the miniaturization thereof. A water hole is formed in the heater cover 20 so that water in an area other than the isolated space in the storage tank 10 can be replenished in the isolated space, And can be opened and closed by a solenoid valve or the like provided in the water supply hole of the water supply unit 20. The heater cover 20 may further include a column portion 22 protruding downward toward the column portion 10c of the storage tank 10.

On the other hand, the heater cover 20 may further include a discharge pipe 25 for discharging the bubbles present in the flow path space to the outside of the storage tank. Bubbles that can be generated in the circulation process of the hot water may cause another noise, and the heater cover 20 may be formed as a structure for discharging the generated bubbles in the circulation system.

The discharge pipe 25 is preferably located above the outlet port 10b of the storage tank 10 and is preferably located at an upper portion extending vertically to the inlet port of the motor pump and the outlet port of the storage tank So that bubbles generated in the circulation system can be discharged naturally along the discharge pipe 25. In addition, the discharge pipe (25) may have a pipe structure extending to the upper cover of the storage tank (10) so that it can be isolated from the water in the storage tank and discharged to the outside of the storage tank. Thus, the noise generated in the hot water supply device can be further reduced through the structure for smooth discharge of bubbles generated in the circulation system.

The heater (30) is installed in the isolated space and can heat water circulated through the isolated space. That is, the heater 30 does not need to heat all the water stored in the storage tank 10, but only a part of the water circulating in the isolated space needs to be heated and maintained at a temperature. . The heater (30) may be realized by an electric heating method, and may be formed in a U shape and horizontally installed with respect to the vertical direction.

The motor pump 50 drives a pump using a motor to extrude hot water heated by the heater 30 into a hot water mat and press water into the isolated space from the hot water mat to circulate water .

It is more effective to design the motor pump 50 such that it can be installed under the storage tank 10 in particular. That is, since the water inlet pipe 52 of the motor pump 50 is locked below the water depth of the water in the storage tank 10, the inflow of air is prevented to solve the air noise problem. In addition, since the motor pump 50 is disposed vertically with the storage tank 10, it can be optimally designed in a minimum space. And the transmission of the driving noise of the motor pump 50 can be reduced.

The motor pump 50 is formed with an inlet port connected to the outlet port 10b of the storage tank 10 on the upper side so that water discharged from the outlet port 10b of the storage tank 10 can be directly received, A water inlet pipe 52 surrounding the inlet port of the motor pump 50 and inserted into the water outlet pipe of the storage tank 10 may be protruded upward. The inlet pipe 52 of the motor pump 50 is formed to have a size corresponding to the outlet port 10b of the storage tank 10 and inserted into the outlet pipe of the storage tank 10, And is formed to have a predetermined length so as to be immediately adjacent to the outlet 10b. Therefore, it is possible to prevent hot water from being directly brought into direct contact with the damper 100, so that thermal deformation of the damper 100 can be prevented.

The motor pump 50 may be installed on the motor pump housing 60 and an elastic body 110 such as a sponge for noise and vibration reduction may be interposed between the motor pump housing 60 and the motor pump housing 60. have.

The damper 100 seals between the inlet pipe 52 of the motor pump 50 and the outlet pipe of the storage tank 10 and may be made of an elastic body 110 for reducing noise and vibration.

In particular, the damper 100 may have a multi-tube structure. That is, the damper 100 includes a pipe-type storage tank engaging portion 112 having a ring-shaped groove 112a having a predetermined depth in which the water-discharging pipe of the storage tank 10 is inserted in the vertical direction, A pipe type motor pump engaging portion 114 having a hollow formed therein to receive the uptake pipe 52 in the vertical direction and a connecting portion 116 connecting the motor pump engaging portion 114 and the storage tank engaging portion 112 Lt; / RTI > Therefore, the damper 100 can be easily coupled to and separated from the water outlet pipe of the storage tank 10 and the water inlet pipe 52 of the motor pump 50. Also, the damper 100 can be uniformly pressed over the entire circumference of the water outlet pipe of the storage tank 10 and the water inlet pipe 52 of the motor pump 50, so that the coupling property and air tightness are excellent. The connecting portion 116 of the elastic body 110 of the damper 100 is formed at least once in a corrugated shape for elastic deformation between the water outlet pipe of the storage tank 10 and the water inlet pipe 52 of the motor pump 50 . The connecting portion 116 of the elastic body 110 of the damper 100 is formed to have a substantially M-shaped cross-section with the portion of the storage tank coupling portion 112 and the motor pump coupling portion 114 of the elastic body 110 . The connection portion 116 of the elastic body 110 of the damper 100 is connected to the upper end of the storage tank coupling portion 112 of the elastic body 110 and the upper end of the motor pump coupling portion 114 of the elastic body 110 Or the like. The second clamp ring 130 to be described later can be coupled to the motor pump coupling portion 114 of the elastic body 110 from the outside of the elastic body 110 to facilitate assembly and disassembly of the damper 100 .

The elastic body 110 of the damper 100 may further include a flange portion 118 in the form of a ring which surrounds the upper end of the storage tank coupling portion 112 and is in close contact with the outer surface of the bottom of the storage tank 10 So that the coupling force between the damper 100 and the damper coupling portion 10d of the storage tank 10 can be further improved.

The elastic body 110 of the damper 100 is protrudingly formed on the lower portion of the motor pump engaging portion 114 of the elastic body 110 to prevent the second clamp ring 130 from moving downward ). The engaging step 119 of the elastic body 110 may be formed in a ring shape like a flange at the lower end of the motor pump engaging part 114.

Meanwhile, the damper 100 is connected to the water outlet pipe of the storage tank 10 by connecting the storage tank coupling portion 112 of the elastic body 110 to the storage tank 10 and the motor pump 50, And a second clamp ring 130 which compresses the first clamp ring 120 and the motor pump coupling portion 114 of the elastic body 110 to the water inlet pipe 52 of the motor pump 50 can do. Particularly, the second clamp ring 130 is formed of a coil spring having a predetermined length in the vertical direction, so that the damper 100 can be uniformly distributed over the entire upper and lower lengths of the intake pipe 52 of the motor pump 50, To the water inlet pipe 52 of the pump 50. The inlet pipe 52 of the motor pump 50 is connected to the elastic pipe 110 of the elastic body 110 while the second clamp ring 130 of the coil spring is inserted into the motor pump coupling part 114 of the elastic body 110, The damper 100, the storage tank 10, and the motor pump 50 can be easily and simply coupled to each other.

The water circulation process of the hot water supply apparatus according to an embodiment of the present invention will now be described.

When the motor pump 50 and the heater 30 are driven, water is taken from the hot water mat to the storage tank 10 through the inlet 10a of the storage tank 10, And is returned to the flow space. The water circulated in the isolated flow path space is heated to a predetermined temperature by the heater (30). The heated water in the isolated flow path space is discharged to the motor pump 50 through the outlet port 10b of the storage tank 10 and the inlet port 10a of the motor pump 50, 50 to the hot water mat.

At this time, since only the water circulating in the isolated flow path space among the water stored in the storage tank 10 can be heated, the heater 30 quickly heats the water in the isolated flow path space to the outflow temperature, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It should also be understood that many modifications and variations are possible without departing from the scope of the invention, as would be understood by one of ordinary skill in the art.
