Description

Instantaneous heating device

Technical Field

The present disclosure relates to an instantaneous heating apparatus that heats introduced water to a predetermined temperature in a relatively short period of time and supplies the heated water to a user, and more particularly, to an instantaneous heating apparatus capable of significantly reducing deformation of a heating passage that heats water while the water flows therein.

Background

The hot water tank is a device that heats stored water to a predetermined temperature and then supplies the heated water to a user. For this purpose, the hot water tank needs to constantly maintain the stored water at a predetermined temperature. For example, when the temperature of water heated to a predetermined temperature becomes lower than the predetermined temperature, the hot water tank repeats reheating of water to the predetermined temperature or higher, so that the stored water is constantly maintained at the predetermined temperature.

In this way, since the hot water tank needs to constantly maintain the stored water at a predetermined temperature, a relatively large amount of energy is required to heat the water, and since the water is stored in the hot water tank for a long time, there has been a sanitary problem due to corrosion of the inner surface of the hot water tank or scale thereon.

in order to solve such problems of such a hot water tank, an instantaneous heating device, which heats water to a predetermined temperature in a relatively short period of time and supplies the heated water to a user, has been developed.

Accordingly, since the instantaneous heating apparatus heats only a required amount of water to a predetermined temperature and supplies the heated water to a user, a relatively small amount of energy is required to heat the water, and since the instantaneous heating apparatus does not store the water, it becomes sanitary.

Generally, such instantaneous heating devices are configured to directly heat flowing water. For this purpose, the instantaneous heating device comprises a heating channel that heats the water as it flows therein.

The heating channel directly heats the flowing water and has the longest possible length in order to increase the time for heating the water. For this purpose, the heating passage is formed by combining various types of members, not only one member. For example, the heating passage is formed by inserting one member inside the other member in a fitted manner.

Meanwhile, the heating passage has a predetermined volume so as not to locally overheat the water when the water flows.

However, when the heating passage is formed in such a manner as a combination of the above-described members, the heating passage is relatively frequently deformed in the formation of the heating passage or in the use of the instantaneous heating device, so that the heating passage cannot have a predetermined volume.

Accordingly, the water flowing in the heating passage is locally overheated relatively frequently in the deformed portion of the heating passage, and water splash may occur when the water is discharged through a discharge member such as a cock or a faucet.

As described above, when water is splashed, a user accident such as a burn caused by the splashing of water may occur.

further, fig. 4 and 5 are views of a heating passage formed between a heating member and a passage forming member by allowing the passage forming member to come into close contact with the heating member by means of a pressing member according to an embodiment of the instantaneous heating apparatus of the present disclosure. Fig. 6 is a sectional view illustrating the operation of an embodiment of an instantaneous heating device according to the present disclosure as illustrated in fig. 3.

An embodiment of the instantaneous heating device according to the present disclosure may include a water inlet part 200, a flow part 300, a heating part 400, and a water outlet part 500.

Water may flow into the water inlet part 200 from the outside, as illustrated in fig. 6. For this purpose, a water inlet passage 210 may be formed in the water inlet part 200.

The water inlet channel 210 may have, for example, an 'L' shape, as illustrated in fig. 3. However, the shape of the water inlet passage 210 is not particularly limited. Any shape may be used as long as water can be introduced to flow.

The water inlet component 200 may include a water inlet nipple 220. A portion of the aforementioned water inlet passage 210 may be formed within the water inlet nipple 220. The water inlet nipple 220 may be connected to a water source (not shown), such as a storage tank or a water filter, by, for example, a fitting member (not shown) or the like.

Accordingly, as illustrated in fig. 6, water from a water source may be introduced into the water inlet passage 210 of the water inlet nipple 220 to flow in the water inlet passage 210.

a sealing member insertion groove 230 may be formed on the water inlet part 200. As illustrated in fig. 2 and 3, a sealing member O, such as an O-ring, may be inserted in the sealing member insertion groove 230. This may allow a space between the water inlet part 200 and a water inlet side housing member 610, the water inlet side housing member 610 being included in a housing part 600 to be described later, the water inlet side housing member 610 covering the water inlet part 200.

The water inlet component 200 may include a temperature sensor (not shown). A temperature sensor may be provided in the water inlet part 200 to measure the temperature of the water flowing in the water inlet passage 210 of the water inlet part 200.

For example, a temperature sensor may be provided in the water inlet nipple 220 of the water inlet component 200. However, the position of the temperature sensor in the water inlet part 200 is not particularly limited, but the temperature sensor may be provided in any position of the water inlet part 200.

Further, the temperature of the water flowing in the water inlet passage 210 measured by the temperature sensor may be used to adjust a heating value of the heating member 400, for example, when the water flowing in the heating passage R is heated by the heating member 400 to be described later.

As illustrated in fig. 6, water introduced into the water inlet part 200, i.e., the water inlet channel 210 of the water inlet part 200, may flow in the flow part 300.

To this end, the flow part 300 may include a passage forming member 310. As illustrated in fig. 3, the passage forming member 310 may be disposed inside the heating member 400. In addition, a channel forming groove 312 may be formed on the outer circumference of the channel forming member 310.

Accordingly, the heating passage R may be formed between the heating member 400 and the passage forming member 310, as illustrated in fig. 3. The water introduced into the water inlet passage 210 of the water inlet part 200 may flow in the heating passage R, as illustrated in fig. 6.

The channel forming groove 312 formed in the channel forming member 310 may be, for example, spiral-shaped, as illustrated in fig. 2. Correspondingly, the heating channel R may also be spiral-shaped.

However, the shape of the passage forming groove 312 is not particularly limited, and any shape such as a zigzag shape or the like may be used as long as the heating passage R may be formed between the heating member 400 and the passage forming member 310.

A first connection hole 313 connecting the water inlet passage 210 to the heating passage R may be formed in one side, e.g., a lower portion, of the passage forming member 310, as illustrated in fig. 2 and 3. Further, as illustrated in fig. 3, a portion of the water inlet part 200 may be inserted in one side, e.g., a lower portion, of the insertion part 311 formed inside the passage forming member 310, so that the water inlet passage 210 may be connected to the heating passage R through the first connection hole 313.

Accordingly, as illustrated in fig. 6, water introduced into the water inlet passage 210 of the water inlet part 200 may move to the heating passage R through the first connection hole 313 to flow in the heating passage R.

As illustrated in fig. 2 and 3, a second connection hole 314 connecting a water outlet passage 510 to be described later to the heating passage R may be formed in the other side of the passage forming member 310, for example, in the upper portion, the water outlet passage 510 being formed in the water outlet part 500. Further, a portion of the water outlet part 500 may be inserted in the other side of the insertion part 311 of the passage forming member 310, for example, in the upper portion, so that the water outlet passage 510 may be connected to the heating passage R through the second connection hole 314.

Accordingly, the water flowing in the heating passage R may move to the water outlet passage 510 of the water outlet part 500 through the second connection hole 314 and flow in the water outlet part 500, and then be discharged to the outside.

As illustrated in fig. 3, a fitting hole 311a may be formed in the aforementioned insertion part 311 of the passage forming member 310. As illustrated in fig. 3 and 5, a fitting protrusion 322a may be inserted in a fitting hole 311a of such an insertion part 311, the fitting protrusion 322a being formed on a pressure acting member 322, the pressure acting member 322 being included in a pressing part 320 to be described later, the pressing part 320 being included in the flow part 300. This may allow the pressure-applying member 322 to be stably fixed within the insertion part 311 of the passage forming member 310.

The passage forming member 310 may be formed of silicone. The silicone resin may have a relatively low thermal deformation point and does not have a bad influence on water when in contact with water, such as emission of harmful substances such as carcinogens.

In addition, since the silicone has a relatively high elasticity, the silicone may allow the portion of the passage forming member 310 other than the passage forming groove 312 to be easily brought into close contact with the heating member 400 by the pressing member 320 as described below to form the heating passage R.

therefore, when the passage forming member 310 is formed of silicone to form the heating passage R between the passage forming member 310 and the heating member 400, the heating passage R is not deformed or closed due to thermal deformation, and water flowing in the heating passage R is not contaminated.

In addition, the pressing part 320 may allow the portion of the passage forming member 310 other than the passage forming groove 312 to be easily brought into close contact with the heating member 400 to easily form the heating passage R.

However, the material forming the passage forming member 310 is not limited to the aforementioned silicone resin, and any well-known material may be used as long as it can have a relatively low thermal deformation point, does not contaminate water when in contact with water, and can have a relatively high elasticity.

as illustrated in fig. 2 and 3, the flow unit 300 may further include a compression member 320. The pressing part 320 may allow the passage forming member 310 to be in close contact with the heating member 400 so as to form a heating passage R between the heating member 400 and the passage forming member 310, as illustrated in fig. 4 and 5.

Accordingly, compared to the heating passage R formed between the passage forming member 310 and the heating member 400 by fittingly inserting the passage forming member 310 in the heating member 400, the deformation of the heating passage R may be significantly reduced.

Accordingly, when the water flowing in the heating passage is locally overheated and discharged to the outside, the occurrence of water splash can be significantly reduced, and user accidents such as scalding caused by the splashed water when the water is locally overheated and discharged can be prevented.

For this purpose, the pressing part 320 may include a pressing member 321. As illustrated in fig. 3 and 4, the pressing member 321 may be inserted in the insertion part 311 of the passage forming member 310. Further, the pressing member 321 may press the passage forming member 310 toward the heating member 400.

Accordingly, as illustrated in fig. 5, the passage forming member 310 may be expanded by its elasticity such that portions of the passage forming member 310 other than the passage forming groove 312 may be in close contact with the heating member 400.

Such pressing members 321 may be provided in plural. For example, as illustrated in fig. 2, the number of the pressing members 321 may be two. However, the number of the pressing members 321 is not particularly limited, but any number of the pressing members 321 may be provided.

Further, the pressing members 321 may be coupled to each other to form a hollow elliptical or polygonal cylinder corresponding to the shape of the insertion part 311 of the passage forming member 310. For example, as illustrated in fig. 2, since the two pressing members 321 may have a shape in which a hollow cylinder is vertically cut in half, the pressing members 321 may be coupled to each other to form the hollow cylinder.

However, as described above, the number of the pressing members 321 may be three or more, and the pressing members 321 may be coupled to each other to form an elliptical or polygonal cylinder.

As illustrated in fig. 4 and 5, the pressing members 321 of the aforementioned configuration may press the passage forming member 310 radially, i.e., in an outer radial direction of the pressing members 321, wherein all the pressing members 321 are inserted in the insertion part 311 of the passage forming member 310. Further, as described above, this may allow the portion of the passage forming member 310 except for the passage forming groove 312 to be expanded by elasticity to be in close contact with the heating member 400.

The pressing part 320 may further include a pressure acting member 322. The pressure application member 322 may apply pressure to the pressing member 321.

For this purpose, the pressure acting member 322 may have a shape corresponding to a cylindrical, elliptical, or polygonal cylinder of a hollow elliptical or polygonal body formed by coupling the pressing members 321, as illustrated in fig. 2.

Further, the outer diameter D1 of the pressure acting member 322 may be larger than the inner diameter D2 of the hollow elliptical or polygonal body formed by coupling the pressing member 321.

Accordingly, when the pressure application member 322 is inserted into the hollow oval or polygonal body formed by the pressing members 321, the pressing members 321 are inserted into the insertion parts 311 of the passage forming member 310, and when the pressing members 321 are extended, pressure may be applied to the pressing members 321 to press the passage forming member 310 in the outer radial direction.

The heating member 400 may heat the water flowing in the flow member 300. That is, as illustrated in fig. 6, the heating member 400 may heat water flowing in the heating passage R formed together with the passage forming groove 312 of the passage forming member 310.

As described above, since the water flowing in the heating passage R is directly heated by the heating member 400, the water can be heated to a desired temperature in a relatively short period of time.

The heating part 400 may include a heating member 410 and a heater 420.

The passage forming member 310 may be disposed inside the heating member 410. Accordingly, the portion of the passage forming member 310 other than the passage forming groove 312 may be in close contact with the inner surface of the passage forming member 310 to form the heating passage R.

As illustrated in fig. 2, the heating member 410 may be, for example, in the shape of a hollow cylinder. However, the shape of the heating member 410 is not particularly limited, and any shape such as a hollow elliptical or polygonal cylinder may be used as long as the passage forming member 310 may be disposed inside the heating member 410.

The heating member 410 may be formed of stainless steel. Accordingly, since the heating member 410 is relatively rapidly heated by the heater 420 to be described below due to its high thermal conductivity, the heating member 410 can more rapidly heat the water flowing in the heating passage R. In addition, the heating member 410 may not be corroded by water.

However, the material forming the heating member 410 is not particularly limited, but any material may be used as long as it may have high thermal conductivity and corrosion resistance to water.

As illustrated in fig. 2, a heater 420 may be attached to the heating member 410. In addition, the heater 420 may heat the heating member 410. Such a heater 420 may be a surface type heater. However, the heater 420 is not particularly limited, but any well-known element that can heat the heating member 410, such as an electric heating wire, may be used.

As illustrated in fig. 6, water heated by the heating member 400, that is, hot water, may be discharged to the outside through the water outlet member 500.

For this purpose, a water outlet passage 510 may be formed in the water inlet part 500.

The water outlet channel 510 may have, for example, an 'L' shape, as illustrated in fig. 3. However, the shape of the water outlet passage 510 is not particularly limited, and any shape may be used as long as water heated by the heating member 400 can be discharged to the outside.

The water outlet member 500 may include a water outlet nipple 520. A portion of the aforementioned water outlet passage 510 may be formed in the water outlet nipple 520. Further, the water outlet nipple 520 may be connected to a discharge member (not shown) such as a cock or a faucet by, for example, a fitting member (not shown) or the like.

Accordingly, as illustrated in fig. 6, water, i.e., hot water, heated by the heating member 400 while flowing in the heating passage R may move to the water outlet passage 510 and then may be discharged to the outside through the water outlet passage 510 of the water outlet nipple 520.

The sealing member insertion groove 530 may be formed on the water outlet part 500. As illustrated in fig. 2 and 3, a sealing member O, such as an O-ring, may be inserted in the sealing member insertion groove 530. This may allow a space between the water outlet part 500 and a water outlet side case member 620, the water outlet side case member 620 being included in a case part 600 to be described later, the water outlet side case member 620 covering the water outlet part 500.

The water outlet member 500 may also include a temperature sensor (not shown). A temperature sensor may be provided in the water outlet part 500 in order to measure the temperature of the water flowing in the water outlet channel 510 of the water outlet part 500.

For example, a temperature sensor may be provided in the water outlet nipple 220 of the water outlet member 500. However, the position of the temperature sensor in the water outlet part 500 is not particularly limited, but the temperature sensor may be provided in any position of the water outlet part 500.

further, the temperature of the water flowing in the water outlet passage 510 measured by the temperature sensor may be used to adjust the heating value of the heating member 400 so that the water flowing in the heating passage R is not overheated when the water flowing in the heating passage R is heated by, for example, the aforementioned heating member 400.

As illustrated in fig. 1 and 2, the instantaneous water heater 100 according to an embodiment of the present disclosure may further include a housing part 600.

As illustrated in fig. 1 and 3, the housing part 600 may cover the water inlet part 200, the heating part 400, and the water outlet part 500. Such a cover member 600 may allow the water inlet part 200, the flow part 300, the heating part 400, and the water outlet part 500 to stably maintain the connection therebetween even when the pressure of water drawn into the water inlet part 200 is relatively high.

As illustrated in fig. 1, the case part 600 may include a water inlet side case member 610 and a water outlet side case member 620.

As illustrated in fig. 3, the water inlet side cover member 610 may cover a portion of the water inlet part 200 and the heating part 400. For this purpose, the water inlet side cover member 610 may have a cylindrical shape of which an upper portion is opened. However, the shape of the water inlet side housing member 610 is not particularly limited, and any shape may be used as long as the water inlet side housing member 610 can cover a part of the heating member 400.

As illustrated in fig. 3, the first exposure hole 611 may be formed in the water inlet side cover member 610, for example, in a lower surface of the water inlet side cover member 610. Accordingly, the water inlet nipple 220 of the water inlet part 200 may pass through the first exposing hole 611 to be exposed to the outside. This may allow a drain member, such as a faucet or a faucet, to be easily connected to the water inlet nipple 220.

The coupling groove 612 may be formed on the water inlet side housing member 610, for example, on the inner side of the open upper portion of the water inlet side housing member 610. The coupling groove 612 may have an 'L' shape, as illustrated in fig. 2.

A coupling protrusion 622 to be described later may be inserted into the coupling groove 612, the coupling protrusion 622 being formed on the water outlet side housing member 620. Accordingly, the water outlet side housing member 620 may be coupled to the water inlet side housing member 610.

the shape of the coupling groove 612 is not particularly restricted, but any well-known shape may be used as long as the coupling protrusion 622 of the water outlet side housing member 620 may be inserted in the coupling groove 612 so that the water outlet side housing member 620 may be coupled to the water inlet side housing member 610.

The water outlet side housing member 620 may be coupled to the water inlet side housing member 610. In addition, the water outlet side cover member 620 may cover the remaining portion of the heating part 400 and the water outlet part 500.

For this purpose, the water outlet side housing member 620 may have a cylindrical shape of which a lower portion is opened. However, the shape of the water outlet side housing member 620 is not particularly limited, and any shape may be used as long as the water outlet side housing member 620 can cover the remaining portion of the heating part 400 and the water outlet part 500.

As illustrated in fig. 3, the second exposing holes 621 may be formed in the water outlet side case member 620, for example, in an upper surface of the water outlet side case member 620. Accordingly, the water outlet nipple 520 of the water outlet part 500 may pass through the second exposing hole 621 to be exposed to the outside. This may allow the water outlet nipple 520 to be easily connected to a water source.

For example, the coupling protrusion 622 may be formed on the outside of the open lower portion of the water outlet side housing member 620.

Further, a lower portion of the water outlet side housing member 620 may be inserted in an upper portion of the water inlet side housing member 610. The coupling protrusion 622 of the water outlet side housing member 620 may be inserted into the above-mentioned coupling groove 612 of the water inlet side housing member 610, so that the water outlet side housing member 620 may be coupled to the water inlet side housing member 610.

The shape of the coupling protrusion 622 is not particularly limited, and any shape may be used as long as the coupling protrusion 622 can be inserted into the coupling groove 612 of the water inlet side housing member 610.

The mounting hole 623 may be formed in the water outlet side housing member 620. A bimetal (not shown) may be installed in the installation hole 623, or a wire or the like connected to the heater 420 may pass through the installation hole 623.

As described above, the use of the instantaneous heating apparatus according to an embodiment of the present disclosure may allow the passage forming member to be brought into close contact with the heating member by the pressing member so as to form the heating passage formed between the heating member and the passage forming member, which heats water while the water flows therein, may significantly reduce deformation of the heating passage, may significantly reduce the occurrence of water splash when the water flowing in the heating passage is locally overheated and discharged to the outside, and may prevent user accidents caused by overheating, such as burns caused by splashed water.

The instantaneous water heater as described above is not limited to the application of the configuration of the foregoing embodiments thereof, but all or a part of the embodiments may be selectively combined to be configured with various modifications.
