Description

Instantaneous water heater {INSTANTANEOUS WATER HEATER}

The present invention relates to an instantaneous water heater that instantly heats an incoming water to make hot water and then flows it out. More particularly, the present invention relates to an instantaneous water heater that minimizes water stagnation during heating and stagnation of water.

The instantaneous water heater is a device that instantaneously heats the incoming water to make it into hot water and then drains it.

In this instantaneous water heater, a flow path through which water flows is formed in a zigzag. The outside of the instantaneous water heater is provided with a heater for heating the water. In addition, the instantaneous water heater is provided with an inlet port and an outlet port connected to the flow path.

With this configuration, the water flowing into the flow path through the inlet provided in the instantaneous water heater flows in a zigzag manner along the flow path. In addition, when heat is transferred to the zig-zag moving water by the operation of the heater, the water is heated and becomes hot water. Thus, hot water produced flows out through the outlet.

Since the flow path through which water flows as described above is formed in a zigzag shape, the instantaneous water heater conventionally has a relatively large stagnation region where water stagnates. In addition, since the water does not flow and stagnates in the stagnation region, more heat than necessary is transferred to the stagnant water in the stagnation region. As a result, the water is locally heated to the steam generating temperature, and water is generated when the water flows out through the flow path or through the outlet and is supplied to the user. As a result, a safety accident such as a user wearing an image occurs.

The inlet /

The inflow / outflow unit 200 may include an inflow port 211 and an outflow port 221. Water may be introduced through the inlet 211 as shown in FIG. In addition, as shown in FIGS. 5 and 6, water may flow out through the outlet 221.

The inflow / outflow unit 200 may include an inflow member 210 and an outflow member 220.

The inlet member 210 may be provided with the inlet 211 described above. The inflow member 210 may be connected to an open side of the body member 310, which will be described later, included in the body portion 300. Accordingly, the inflow member 210 can be connected to the second flow path R2 formed in the main body 300. [ The first flow path R1 formed in the main body 300 may be connected to the inlet 211.

The inflow member 210 may have a first connection part 212, a first member insertion part 213, and a second connection part 214.

The first connection part 212 may be inserted into an open side of a heating member 320, which will be described later, included in the main body 300, as shown in FIGS. The first connection part 212 may be provided with a sealing member SR. Accordingly, when the first connection portion 212 is inserted into one opened side of the heating member 320, the first connection portion 212 can be sealed between the open side of the heating member 320.

As shown in FIGS. 3 and 4, a first through hole 212a may be formed in the first connection portion 212 as shown in FIG.

The first member insertion portion 213 may be provided inside the first through hole 212a formed in the first connection portion 212. [ One end of the fluid member 330, which will be described later, included in the main body 300 may be inserted into the first member insertion portion 213.

One end of the flow member 330 may have a small cross-section at the center of the flow member 330. In addition, a sealing member SR may be provided at one end of the flow member 330. Therefore, when one end of the flow member 330 is inserted into the first member insertion portion 213, the first member insertion portion 213 can be sealed between one end of the flow member 330 and the first member insertion portion 213. [

The first member insertion portion 213 may be formed with a first flow path R1 to be described later formed through the flow member 330 and a first connection flow path RC1 to be connected to the inlet 211. [ Accordingly, the water introduced into the inlet 211 flows into the first flow path R1 of the flow member 330 through the first connection flow path RC1 and flows as shown in FIG.

As shown in FIGS. 3 and 4, the second connection portion 214 may have a second through hole 214a connected to the first through hole 212a. The outflow member 220 may be inserted into and connected to the second through hole 214a. The outflow member 220 may be provided with a sealing member SR. Therefore, when the outflow member 220 is inserted into the second through hole 214a, the second through hole 214a can be sealed between the outflow member 220 and the second through hole 214a.

The second passage R2 may be formed between the first through hole 212a and the first member insertion portion 213 and the second connection passage RC2 may be formed to be connected to the second through hole 214a. 6, water flowing through the second flow path R2 formed in the main body 300 can flow into the second through hole 214a through the second connection flow path RC2. The water flowing into the second through hole 214a may flow through the second through hole 214a and may flow out through the outlet 221 of the outflow member 220. [

The outflow member 220 may be provided with an outlet 221. Further, the second flow path R2 may be connected to the inflow member 210 so as to be connected to the outflow port 221. [ The outflow member 220 may be inserted into the second through hole 214a of the inflow member 210 and connected to the inflow member 210 as described above. The outlet 221 is connected to the second connection passage RC2 connected to the second flow passage R2 through the second through hole 214a so that the second flow passage R2 is communicated with the outlet port 221).

Meanwhile, the first sensor mounting portion 215 may be formed at a portion of the inflow member 210 adjacent to the inlet 211. The first sensor mounting part 215 may be provided with a temperature sensing part TS. Thus, the temperature of the water flowing into the inlet 211 can be sensed.

The temperature sensing unit TS may include a temperature sensor S and a coupling member B. [ A sensor hole 215a and a coupling hole 215b may be formed in the first sensor mounting portion 215. [

The sensor hole 215a may be connected to the inlet 211. Then, the temperature sensor S can be inserted into the sensor hole 215a. The temperature sensor S can sense the temperature of the water flowing into the inlet 211 by the temperature sensor S. [

The temperature sensor S may be provided with a sealing member SR. Accordingly, when the temperature sensor S is inserted into the sensor hole 215a, the space between the sensor hole 215a and the temperature sensor S can be sealed.

And the engaging member B can be engaged with the engaging hole 215b. Accordingly, the temperature sensing part TS can be securely mounted on the first sensor mounting part 215.

The second sensor mounting portion 216 may be formed at a portion of the inflow member 210 adjacent to the first through hole 212a or the second connection channel RC2 or the second through hole 214a. The second sensor mounting portion 216 may be provided with a temperature sensing portion TS including a temperature sensor S and a coupling member B. [ Accordingly, the temperature of the water flowing out through the outlet 221 can be sensed.

The sensor hole 216a into which the temperature sensor S is inserted and the coupling hole (not shown) in which the coupling member B is coupled may be formed in the second sensor mounting portion 216 as well.

The body portion

The inflow / outflow unit 200 may be connected to one side of the main body unit 300. In the main body 300, the water introduced through the inlet 211 may be heated and may flow out through the outlet 221. In addition, water can be minimized when the water stagnates and water is heated.

For this purpose, the main body 300 may include a first flow path R1 and a second flow path R2. The congestion of water may occur only in the third connection channel RC3, which will be described later, which connects the first flow path R1 and the second flow path R2. Thus, the section where the water stagnates can be minimized.

The first flow path R1 may be connected to the inlet 211. 5, the water introduced into the inlet 211 may flow in the direction of the closing part 400 along the first flow path R1.

The second flow path R 2 may be connected to the first flow path R 1 and the outlet port 221. Accordingly, as shown in FIGS. 5 and 6, the water flowing in the direction of the closing part 400 along the first flow path R1 can flow into the second flow path R2. The water flowing into the second flow path R2 flows along the second flow path R2 in the direction of the flow-in part 200 and can be heated and flowed out through the outlet 211 as shown in FIG.

As shown in FIGS. 3 and 4, the thickness T2 of the second flow path R2 may be thinner than the thickness T1 of the first flow path R1. The cross section of the first flow path R1 may be circular, elliptical or polygonal, and the cross section of the second flow path R2 may be ring-shaped. However, the shape of the cross section of the first flow path R1 is not particularly limited, and any shape can be used.

Accordingly, it is possible to heat the same amount of water at a desired temperature more quickly by heating the water flowing through the second flow path R2 than by heating the water flowing through the first flow path R1.

In addition, since the flow velocity of the water flowing through the second flow path R2 is relatively larger than the flow velocity of the water flowing through the first flow path R1, it is possible to prevent water from being locally heated up to the steam generation temperature to generate water droplets. Then, a safety accident such as a user wearing an image may not occur.

On the other hand, the second flow path R2 may become narrower toward the outlet 221. Thereby, as the water flows from the second flow path R2 to the outlet 221, the same amount of water can be heated to a desired desired temperature more quickly.

As the flow rate of the water from the second flow path R2 to the outlet 221 increases, the water can be locally heated to the steam generation temperature to prevent water from being generated. Therefore, as described above, a safety accident such as a user wearing an image may not occur.

To this end, the body portion 300 may include a body member 310, a heating member 320, and a flow member 330, as shown in FIG.

The body member 310 can be opened on one side and the other side. The inflow / outflow unit 200 may be connected to the open side of the body member 310. For example, the aforementioned inflow member 210 of the inflow / outflow unit 200 may be connected to one opened side of the body member 310. In addition, the closing part 400 may be connected to the other open side of the body member 310.

The body member 310 may include an upper member 311 and a lower member 312 connected to the upper member 311. The main body 300 can be easily completed by connecting the upper member 311 and the lower member 312 while the flow member 330 is inserted into the heating member 320. [ In addition, the inflow / outflow unit 200 and the closing unit 400 can be easily connected to one side and the other side of the main body 300.

However, the structure of the body member 310 is not particularly limited, and any structure can be used as far as the body member 300 can be formed.

The body member 310, for example, the upper member 311 of the body member 310, may be formed with a bimetal hole 311a. A bimetal (BM) may be provided in the bimetal hole 311a to contact the outside of the heating member 320.

The operation of the heater 321 provided in the heating member 321 can be stopped by the bimetal BM so as to heat the heating member 320 when the heating member 320 is overheated to a predetermined temperature or more. It is also possible to prevent the heating member 321 from being overheated.

For example, the bimetal (BM) may be connected to a power source (not shown) and a heater 321. When the heating member 320 is heated, the power source and the heater 321 are not connected to each other so that the heating member 320 is not operated.

The bimetal BM can be indirectly brought into contact with the outer circumference of the heating member 320 by the contact assistant member 313 as shown in Fig. 2 contacting the outer periphery of the heating member 320. [ To this end, the portion of the contact assistant member 313 that contacts the outer periphery of the heating member 320 may have a shape corresponding to the outer periphery of the heating member 320. [ For example, when the heating member 320 is cylindrical as shown in Fig. 2, the portion of the contact assist member 313 that contacts the outer periphery of the heating member 320 may be curved in shape corresponding to the outer periphery of the cylindrical shape.

As a result, the heat transfer between the heating member 320 and the bimetal (BM) is performed relatively quickly, so that the bimetal (BM) may not be damaged by instantaneous excessive heat transfer.

The heating member 320 may be provided inside the body member 310. One side and the other side can be opened. The heating member 320 may be cylindrical, for example. However, the shape of the heating member 320 is not particularly limited, and any shape can be used as long as one side and the other side are open.

A part of the inflow / outflow unit 200 may be inserted into the open side of the heating member 320. For example, as shown in FIGS. 3 and 4, the first connecting portion 212 formed on the inflow member 210 of the inflow / outflow unit 200 may be inserted into the opened side of the heating member 320.

In addition, a part of the closing part 400 may be inserted into the other open side of the heating member 320. [ For example, the third connecting portion 410 of the closing portion 400 may be inserted into the open other side of the heating member 320, as shown in FIGS. 3 and 4 and described later.

A heater 321 may be provided on the outer circumference of the heating member 320 as shown in FIG. By driving the heater 321, the heating member 320 can be heated. The water flowing through the second flow path (R2) formed between the heating member (320) and the flow member (330) can be heated.

The heater 321 may be a planar heating element. However, the heater 321 is not particularly limited, and any known one can be used as long as it can heat the heating member 320.

The first flow path (R1) may be formed through the flow member (330). Thereby, one side and the other side of the flow member 330 can be opened. The cross section of the first flow path R1 formed in the flow member 330 may be circular, elliptical or polygonal, for example, as described above.

The flow member 330 may be provided inside the heating member 320. Thereby, the second flow path R2 can be formed between the heating member 320 and the flow member 330. [ For example, the ring-shaped second flow path R2 may be formed between the heating member 320 and the flow member 330 as described above.

Closing part

The closure part 400 may be connected to the other side of the body part 300. The third connection part 410 may be formed in the closing part 400. The third connection part 410 may be inserted into the open side of the above-described heating member 320 included in the main body part 300.

The third connection part 410 may be provided with a sealing member SR. Accordingly, when the third connection part 410 is inserted into the other open side of the heating member 320, the other side of the heating member 320 can be sealed between the third connection part 410 and the open side.

The second member insertion portion 411 may be formed in the third connection portion 410. The open end of the flow member 330 may be inserted into the second member insertion portion 411. Accordingly, a third connection channel RC3 for connecting the first flow path R1 and the second flow path R2 can be formed. 3 and 4, the water flowing through the first flow path R1 formed in the flow member 330 flows through the third connection flow path RC3 to the heating member 320 and the flow member 330, And flows into the second flow path R2 formed between the first flow path R2 and the second flow path R2.

The third sensor mounting portion 420 may be formed in the closing portion 300. The third sensor mounting portion 420 may be provided with a temperature sensing portion TS including a temperature sensor T and a coupling member B. [ Thus, the temperature of the water flowing through the third connection passage RC3 can be sensed.

A sensor hole 421 into which the temperature sensor T is inserted and connected to the third connection passage RC3 and a coupling hole 422 through which the coupling member B is inserted may be formed in the third sensor mounting portion 420 . Accordingly, the temperature sensing part TS can be firmly mounted on the third sensor mounting part 420 in a state where the temperature sensor T is inserted into the sensor hole 421.

As described above, by using the instantaneous water heater according to the present invention, it is possible to minimize the stagnation zone in which the water stagnates, minimize the occurrence of water stalls during heating of water, and cause a safety accident And the bimetal may not be destroyed by instantaneous excessive heat transfer, and the instantaneous water heater may not be overheated.

The instant water heater described above is not limited to the configuration of the embodiment described above, but all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments.
