Description

High Efficiency Gas Water Heater

The present invention relates to a high-efficiency gas water heater having a more efficient heat exchange rate and a compact structure and volume. More particularly, the heat of the flame flowing into the heat exchange housing is discharged through the water storage side wall. When the heat exchange efficiency is higher than the water heater and the fresh water level of the low water housing is low, the upper surface of the heat exchange housing can be positioned at the lower side of the rotation path of the floating valve. When the fresh water level is low, a separate vertical support member for the floating valve is provided. Highly efficient heat exchange is possible because the configuration of the burner's mixed fuel gas injection path is formed in a straight way, which eliminates the need for a burner, thereby greatly reducing the installation space of the burner and reducing the overall water heater volume space as well as the installation configuration of the floating valve. At the same time A high efficiency gas water heater with compact volume and configuration.

Generally, various types of gas water heaters that can obtain hot water by heating cold water have been proposed, but the conventional ones are not only complicated in structure but also lose heat energy of the gas burner for heat exchange. There was a problem of this deterioration.

1 is a view showing the internal structure of a conventional water heater.

Referring to the drawings, a conventional gas water heater has a housing 1 in which a water inlet pipe 4 for intermittent inflow of water by a floating valve 5 and a discharge pipe 6 for discharging hot water raised above a predetermined temperature are installed on one side. And, it is installed in the housing 1, the inner flow pipe (2a) is composed of a communication (2) connected to the inside of the housing, and the burner (3) installed on the lower side of the communication to generate a flame.

Accordingly, the water stored in the housing 1 is moved through the flow path tube 2a in the communication, and when the water moves by the flame of the burner 3, the temperature is increased by heat exchange.

However, in the case of such a water heater, since the floating valve 5 should be installed to control the inflow of water, the appearance of the water heater may be increased to secure the receiving space for accommodating the communication 2 and the floating valve 5 in the housing 1. In addition, there is a problem that the heat exchange is exhausted without heat exchange being performed on the upper wall of the communication unit 2, which inevitably lowers the heat exchange efficiency.

The present invention has been made to solve the above problems by configuring the heat of the flame flowing into the heat exchange housing to discharge through the water storage side wall to increase the heat exchange efficiency than the conventional water heater and float when the fresh water level of the low water housing is low Since the upper surface of the heat exchange housing is located at the lower side of the rotation path of the valve, when the freshwater level is low, a separate vertical support member for the floating valve is not required, so the configuration is simple and the mixed fuel gas injection path of the burner is Formed in a straight way, the installation space of the burner can be greatly reduced, thereby reducing the installation space of the floating valve and the overall volume of the water heater, thereby providing high efficiency heat exchange and at the same time providing a high efficiency gas water heater with compact volume and configuration. There is a purpose.

The present invention has the following features to achieve the above object.

The present invention is a water heater for raising the temperature of the fresh water to a high temperature, the water heater is formed on one side of the inlet pipe is intermittent to the inflow and outflow of the inlet water through the floating valve, the discharge pipe is discharged is formed in each receiving space A water storage housing in which the formed inflow water may be temporarily stored; It is located in the water storage housing but the airtightness is maintained so that the fresh water in the water storage housing does not flow into the inside, and a certain accommodation space is formed to accommodate one or more flow pipes, and the upper one side passes through the side wall of the water storage housing and the outside. A heat exchange housing in communication with the lower side and communicating with the outside through the water storage bottom wall; And a burner configured to supply firearms generated by being spaced apart from the lower side of the heat exchange housing by a predetermined interval into the heat exchange housing, wherein the flow pipe of the heat exchange housing is formed such that one side and the other side communicate with the water storage housing and are inclined. And the fresh water in the low water housing is transferred along the oil pipe and heat exchanged by the fire supplied from the burner to increase the temperature of the fresh water.

Here, the floating valve is a floating body floating on the fresh water in the water storage housing, one end is fixedly coupled to the floating body and the other end is coupled to one side of the inlet pipe formed on one side wall of the storage housing floating of the floating body It consists of a link unit for blocking or intermitting the flow of water in the inflow pipe according to the height, the floating body rotated at an angle according to the fresh water in the water storage housing is formed so that the upper surface wall of the heat exchange housing is located on the lower side of the rotation path.

In addition, below the inlet of the flowing water flowing into the storage housing through the inlet pipe, the upper and lower portions are opened in the storage housing wall so that the flowing water flowing into a position formed at a predetermined distance apart is introduced into the storage housing wall at a predetermined depth. The rectangular guide tube having a certain length in the direction is formed.

In addition, on both sides of the inlet pipe coupled to the link portion of the floating valve in the horizontal direction, one side is fixedly coupled to the wall of the water storage housing and the other side is provided with a '┙' shaped support member for supporting both sides of the inlet pipe. Support both sides of the inlet pipe so that the inlet pipe does not swing horizontally by repeated rotation.

In addition, the horizontal tube has an opening side formed at a point spaced apart from the point in communication with the supply pipe of the fuel supply unit is formed a space for mixing the fuel and air supplied from the fuel supply by a predetermined interval.

According to the present invention, the heat of the flame flowing into the heat exchange housing is discharged through the water storage side wall, thereby increasing the heat exchange efficiency than the conventional water heater.

In addition, this allows the floating valve to be supported on the lower side in the rotational direction on the upper surface of the heat exchange housing so that a separate supporting member can be removed and the space where the floating valve was previously installed can be reduced so that the volume of the overall water heater is increased. There is an effect that can be reduced.

In addition, since the mixed fuel gas injection path of the burner is formed in a straight manner, the installation space of the burner is drastically reduced compared to the previous 'c' or 'ㄹ' type injection paths, thereby reducing the overall water heater volume space together with the floating valve configuration. As a result, a water heater having a compact volume and configuration can be constructed.

Referring to the drawings, the high-efficiency gas water heater 1000 according to the present invention includes a water storage housing 100 in which flowing water is temporarily stored, a heat exchange housing 200 located in the water storage housing 100 to perform heat exchange, and the heat exchange housing. It is composed of a burner 300 disposed on the lower side to generate a flame.

Here, the water storage housing 100 has a predetermined accommodation space is formed so that the flowing water can be temporarily stored, the water storage housing 100 is an inlet pipe intermittent entry and exit of the inlet water through the floating valve 400 on one side 110 and a discharge pipe 120 through which water flowing into and rising above a predetermined temperature is controlled by an intermittent means (not shown) such as a valve and discharged, respectively.

Of course, the inlet pipe 110 is formed on the upper side of the water storage housing 100 is introduced at a point higher than the water level of the fresh water flowing, cold water having a low temperature will also be common.

In addition, the flowing water according to the present invention is water used in most homes, offices or factories, and in some cases, may be a fluid rather than water.

In addition, the discharge pipe 120 is a discharge pipe 120 to a height close to the center of the flow pipe 210 is formed in a plurality so that the discharged water is exchanged by the flow pipe 210 of the heat exchange housing 200 to be described later The height of the formation is preferably determined, and the temperature sensor may be provided on the wall surface of the water storage housing 100 in which the discharge pipe 120 is formed in order to control the proper discharge water temperature during discharge.

The sensing data of the temperature sensor is read by a controller (not shown) separately installed to control the operation of the burner 300, which will be described later, when the temperature of the flowing water flowing at the height of the discharge pipe 120 is the desired temperature. The operation of the burner 300 may be stopped to control the heat exchange to be stopped, and when it is low, the operation of the burner 300 may be continuously maintained or the operation of the burner 300 which is stopped may be controlled again.

On the other hand, the heat exchange housing 200 is located in the water storage housing 100 and is configured to maintain the airtight so that the fresh water in the water storage housing 100 does not flow into the inside, such a heat exchange housing 200 in a predetermined accommodation space It is formed so that one or more flow pipes are received.

Here, the flow pipe 210 is configured to be directly exposed to the flame of the burner 300 provided at the lower side of the heat exchange housing 200 so that the flowing water passing through the heat exchange heat is increased.

The oil and water pipe 210 is formed so that both ends and the inclined in one direction and the storage housing 100 is inclined in one direction freely configured to flow in the water storage housing 100 and airtight with the inside of the heat exchange housing 200 In this state, only a flow path through which the flowing water flows is formed so that flames are transferred through the wall of the flowing water pipe 210.

In addition, the water pipe 210 according to the present invention can be configured to increase the heat exchange rate of the flow of water flowing through the water pipe 210 is formed by a plurality of heat radiation fins extending on the outer edge.

In addition, one of the greatest features of the present invention is the installation configuration of such a heat exchange housing 200, which is a conventional heat exchange housing 200 through the bottom wall of the water storage housing 100 and communicate with the outside side The flame of the burner 300 provided in the flow is introduced, the flame is introduced through the upper side of the heat exchange housing 200 communicates with the outside through the upper side wall of the water storage housing 100, thereby Accordingly, the floating valve 400 to intercept the flow of water flowing into the water storage housing is arranged on the side of the heat exchange housing 200.

As the heat exchange housing 200 and the floating valve 400 are arranged in parallel as described above, the volume of the entire water storage housing 100 is inevitably increased, thereby constraining the installation space of the water heater and the amount of fresh water flowed rapidly. On the contrary, the arrangement structure of the heat exchange housing 200 and the floating valve 400 according to the present invention is formed in a series structure of upper and lower as shown in FIGS. 2 and 3 to decrease the volume relatively. It will be.

In addition, since the heat exchange housing 200 according to the present invention is configured to discharge heat through the side wall of the water storage housing 100, heat exchange with fresh water is possible until just before the heat is discharged to the outside, whereby the heat exchange rate is increased. It has an augmented feature.

In addition, when the water level is very low because the upper wall of the heat exchange housing 200 is disposed on the lower side on the path where the floating valve 400 floats in accordance with the water level and rotates up and down, the floating valve 400 is connected to the heat exchange housing 200. As it is supported on the upper wall of the) has the advantage that a separate floating valve 400 supporting member is unnecessary.

On the other hand, the burner 300 is provided to supply fire into the heat exchange housing 200 generated by being spaced apart at a predetermined interval from the opened lower side of the heat exchange housing 200, the burner 300 is the heat exchange housing ( The gas outlet unit 310 spaced apart from a predetermined point on the lower side of the 200 to discharge the mixed fuel gas, and connected to one side of the gas outlet unit 310 to supply fuel and air to the gas outlet unit 310. It is composed of a fuel supply unit 320 and the ignition device 330 is disposed on one side of the gas discharge unit 310 to generate a spark so as to ignite when the mixed fuel gas discharged.

In addition, one of the biggest features of the present invention is the configuration of the gas discharge unit 310, which is a conventional gas inlet flows from the fuel supply unit 320 by forming a mixed gas inlet flow path in the '' 'or' r 'shape Provided time and physical space for the fuel and air to be sufficiently mixed.

However, the gas-outlet part has a large volume of the gas-outlet part due to the inflow structure to increase the volume of the burner 300 and the water heater 1000 as a whole, and the bottleneck of the mixed fuel gas is generated in the curved flow path, so that it is smooth and uniform. The problem that the fuel supply is lowered, the gas discharge unit 310 according to the present invention is a fuel and air is introduced and mixed in a straight manner, but the fuel is uniformly mixed to some extent by putting a certain mixing section is discharged to ignite. .

That is, the gas discharge unit 310 according to the present invention includes a plurality of horizontal pipes 311 having one side communicating with the supply pipe 321 of the fuel supply unit and having a predetermined upper portion open so that the mixed fuel gas to be supplied can be discharged. And a pair of guide plates 312 for guiding the mixed fuel gas discharged as it is vertically installed to correspond to both points in the longitudinal direction of the opening side of the horizontal tube 311 to the upper side, and the pair of guides. The discharge area formed by the pair of guide plates 312 in the longitudinal direction between the plates 312 is partitioned in the longitudinal direction of the horizontal tube 311 so that uniform discharge of the fuel gas and flame are generated. It consists of a partition plate 313.

Here, the horizontal pipe 311 is installed to have a plurality of horizontal linear structure as shown in Figure 6 and the opening at a point spaced apart from the point communicating with the supply pipe of the fuel supply portion to give a mixture space of fuel and air Allow sides to be formed.

'형태로 마주하며 형상적으로 대응되는 웨이브 형상으로 이루어짐이 바람직하다. In addition, the guide plate 312 is composed of a plurality of flames that are separated in a uniform form without forming a flame generated by the ignition of the mixed fuel gas discharged integrally '

It is preferable that the wave shape is opposite to each other in shape and corresponding in shape.

In addition, the partition plate 313 is interposed between the guide plate 312 to be more uniform and the height is formed to be optimal, which can be selectively adopted according to the separation distance with the lower side of the heat exchange housing 200. .

On the other hand, the floating valve 400 is provided to control the flow of water flowing from the inlet pipe 110 according to the fresh water of the storage housing 100, as described above, such a floating valve 400 is in the storage housing (100) Floating body 410 floating on the fresh water and one end is fixedly coupled to the floating body 410 and the other end is hinged and coupled to one side of the inlet pipe 110 formed on one side wall of the water storage housing ( According to the floating height of 410 is made of a link unit for blocking or blocking the inflow of water in the inflow pipe.

Since the configuration of such a floating valve 400 is a known technique, more detailed description thereof will be omitted.

Meanwhile, below the inlet 111 of the flowing water flowing into the storage housing 110 through the inflow pipe 110, the storage water flows into a lower portion of the storage housing so that the flowing water flows into a location formed at a predetermined distance apart. The upper and lower openings are formed in the wall, and the guide tube 312 of the rectangular body having a predetermined length in the vertical direction is coupled to each other. The inflow flow formed at a relatively low temperature by the configuration of the guide tube 312 is a heat exchange. By discharging to the water level formed in the water pipe 210 is formed can be smooth and uniform distribution structure of hot water of high temperature, when the drop directly from the upper inlet pipe 110, the upper side of the water storage housing 100 is continuously vortex It is possible to remove the element is inhibited convection caused by the temperature difference between the smooth running water.

Therefore, the lower opening point of the guide tube 312 is preferably composed of the water level of the water pipe 210 formed of a plurality as described above, the size of the upper opening side of the guide tube 312 is the inlet ( Of course, it should be formed larger than the size of 111).

On the other hand, both sides of the wall of the water storage housing 100 are fixedly coupled to both sides of the inlet pipe 110 coupled to the link part 420 of the floating valve 400, and the other side of both sides of the inlet pipe 110. A support member 600 having a '┙' cross-sectional shape is installed to support both sides of the inflow pipe 110 so that the inflow pipe is not swinged in the horizontal direction by repeated rotation of the link part 420.

Of course, the support member 600 is formed to be spaced apart from the inlet pipe 110 by a predetermined distance from the outer edge of the inlet pipe 110 so as to minimize the fluctuation and in some cases to be in contact with the inlet pipe 110 to support It can also be configured.

As described above, the present invention has been described with reference to one embodiment shown in the drawings, but this is merely an example, and those skilled in the art may realize various modifications and other equivalent embodiments therefrom. I will understand.
