Description

Instant Heater {INSTANTANEOUS WATER HEATER}

The present invention relates to an instantaneous heating device that heats the introduced water to a predetermined temperature in a relatively short time and flows it out to the outside. More specifically, the instantaneous heating device includes a flow section in which a flow path is formed to allow the introduced water to flow for a predetermined time.

In addition, as shown in FIG. 5, the first body forming member 210 and the second body member 220 and the flow unit 400 to be described below are manufactured in the same size, and the flow unit 400 is the first body. In a state located between the forming member 210 and the second body forming member 220, they may be combined with each other by welding or the like. Accordingly, a flow path R by the flow part 400 may be formed between the first body forming member 210 and the second body forming member 220 constituting the apparatus body 200 as described below.

With this configuration, as described later, the water flowing through the inlet 200a flows through the flow path P, which will be described later, formed in the inside of the apparatus main body 200, that is, the flow unit 400, for a predetermined time. Heated by the heating unit 300 provided in the 200 may be outflowed through the outlet 200b. Accordingly, it is not necessary to connect a member for forming a flow path to the first body forming member 210 or the second body forming member 220 separately, or to process the flow path to be formed. Therefore, the manufacturing of the instantaneous heating device 100 can be facilitated, and the manufacturing cost and time of the instantaneous heating device 100 can be reduced.

In this case, both the first heating unit 310 and the second heating unit 320 may be operated, and only one of the first heating unit 310 or the second heating unit 320 is operated to operate the flow path ( Hot water can be produced by heating the water flowing R).

In addition, the heating capacity of the first heating unit 310 and the second heating unit 320 may be different. Therefore, the first heating unit 310 or the second heating unit 320 or both the first heating unit 310 and the second heating unit 320 may be operated to supply the amount of heat required to make hot water.

On the other hand, as shown in Figures 1, 2, 5 and 6, the heating unit 300 may include a surface heater. Accordingly, the water introduced into the apparatus main body 200 through the inlet 200a may be continuously heated while flowing the flow path (P) formed in the flow unit 400 to be described later. As a result, the heating efficiency of the instantaneous heating device 100 can be improved, and the size of the instantaneous heating device 100 can be reduced. The planar heater included in the heating part 300 may be a ruthenox heater as shown in the illustrated embodiment. However, the planar heater included in the heating unit 300 is not limited to the Luthenox heater as in the illustrated embodiment, and any planar heater may be known as long as the planar heater is used.

The flow unit 400 may be provided in the apparatus main body 200 as shown in FIGS. 1, 2, 5, and 6. 1, 2 and 6 in the first insertion space 210a of the first body forming member 210 and the second insertion space 220a of the second body forming member 220 as shown in the embodiment shown in FIG. After the flow unit 400 is inserted, the flow unit 400 may be provided inside the apparatus body 200 by connecting the first body forming member 210 and the second body forming member 220.

In addition, as shown in FIG. 5 and described above, the first body forming member 210, the second body member 220, and the flow unit 400 are manufactured to have the same size, and the flow unit 400 is the first body. In a state located between the forming member 210 and the second body forming member 220, they may be combined with each other by welding or the like.

In addition, the flow unit 400 is heated while the water flowing into the apparatus main body 200 through the inlet (200a) as shown in the embodiment shown in Figures 1 to 3 flows within the apparatus main body 200 for a predetermined time. A flow path P connected to the inlet 200a and the outlet 200b may be formed to be heated by the unit 300.

To this end, the flow unit 400 may include an edge member 410 and a flow path forming member 420, as shown in the embodiment shown in Figs.

1 to 3, the edge member 410 may form an edge of the flow path (P). As shown in the illustrated embodiment, the frame member 410 may have a rectangular shape. However, the shape of the edge member 410 is not limited to a rectangle, and any shape such as a circle or a triangle may be used as long as the edge of the flow path P is formed.

One or more flow path forming members 420 may be connected to the edge member 410 as shown in FIGS. 1 to 3. In addition, the flow path P may be formed by the flow path forming member 420. For example, as shown in the illustrated embodiment, a plurality of flow path forming members 420 are formed in the edge member 410 so as to form a flow path P through which water introduced into the apparatus main body 200 flows in a zigzag fashion. Can be staggered with each other. That is, the plurality of flow path forming members 420 may be alternately connected to the edge member 410 as shown in the illustrated embodiment. Accordingly, as shown in the illustrated embodiment, a zigzag-shaped flow path P may be formed in the flow part 400.

Therefore, as shown in FIG. 4, the water flowing into the apparatus main body 200 through the inlet 200a may pass through the flow path P formed by the edge member 410 and the flow path forming member 420 as described above. It may be heated by the heating unit 300 while flowing along. Then, the water heated to a predetermined temperature may be discharged to the outside through the outlet 200b as shown.

1, 2, 5, and 6, the flow path P includes at least one horizontal portion P1 through which water flows horizontally, and at least one vertical portion through which water flows vertically. (P2) may be included.

In addition, the width of the horizontal portion (P1) can be reduced toward the outlet 200b from the inlet (200a), as shown in the embodiment shown in Figs. Accordingly, the flow rate may be increased toward the outlet 200b. Therefore, the water flowing through the flow path R on the outlet 200b side can be prevented from being locally overheated to generate steam.

5 and 6, the length of the horizontal portion P1 may be longer from the inlet 200a to the outlet 200b. Accordingly, as described above, even if the flow velocity increases toward the outlet 200b, a sufficient amount of heat is supplied to the water flowing through the flow path P, so that the temperature distribution of the water along the cross section of the flow path R may be uniform. . Therefore, it is possible to prevent the water flowing in the flow path P from locally overheating and generating steam.

In addition, the length of the vertical portion (P2) may be changed from the inlet (200a) toward the outlet (200b). As shown in FIGS. 5 and 6, the length of the vertical portion P2 may be shortened from the inlet 200a to the outlet 200b. And, although not shown, the length of the vertical portion (P2) may be longer from the inlet (200a) toward the outlet (200b).

Accordingly, the temperature distribution of the water along the cross section of the flow path R may be uniform. Therefore, it is possible to prevent the water flowing in the flow path P from locally overheating and generating steam.

Meanwhile, in the illustrated embodiment, the flow path P formed by the flow path forming member 420 is formed so that water flows in a zigzag, but the flow path P formed by the flow path forming member 420 is not limited thereto. It can be formed to flow in a spiral. That is, one side of the spirally formed flow path forming member 420 may be connected to the edge member 410. As a result, a spiral flow path P is formed in the flow part 400. In addition, the inlet port 200a or the outlet port 200b may be connected to the center and the outside of the helical flow path P, respectively. As a result, the water introduced into the apparatus main body 200 through the inlet port 200a is heated to a predetermined temperature by the heating unit 300 while flowing in the spiral flow path P of the flow unit 400 and then the outlet port ( 200b) may be discharged to the outside. In addition, the spiral flow path P formed in the flow part 400 may have any shape such as a circular spiral, a triangle, or a square spiral.

On the other hand, the flow unit 400 may also be made of stainless steel like the device body 200 described above. That is, as described above, both the rim member 410 and the flow path forming member 420 included in the flow part 400 may be made of stainless steel. As a result, water may not be contaminated by the flow unit 400. However, the material constituting the flow part 400 is not limited to stainless steel, and any material well known as long as it is a material that prevents water flowing through the flow path P formed in the flow part 400 from being contaminated by the flow part 400. The material is also possible.

That is, the temperature of the water flowing into the inlet 200a is measured by a temperature sensor (not shown), and then a difference from the predetermined temperature required is calculated.

In addition, in the heating unit 300 and the illustrated embodiment, when the amount of heat generated by the first heating unit 310 or the second heating unit 320 is fixed, the flow path P is used to heat the water to a required temperature. You can find the flow rate of water flowing.
