Description

Heating tap

Technical Field

The utility model relates to the technical field of faucets, in particular to a heating faucet.

Background

There is a heating faucet in the prior art that includes a return tube. Because the return pipe always stores water in the return pipe when the heating faucet is stopped, the heating faucet can not be dry-burned even if the water is stopped.

The return pipe generally comprises two straight pipe sections (a first pipe body and a second pipe body) and an inverted U-shaped bent pipe section connecting the two straight pipe sections. Two straight pipe sections of the return pipe are arranged on two sides of a hot water inlet pipe of the heating faucet. The water inlet of the return pipe is connected to the water inlet of the heating faucet, and the water outlet of the return pipe is connected to the water inlet of the hot water inlet pipe. The heating body is arranged around the hot water inlet pipe and is used for heating water in the hot water inlet pipe.

In the conventional heating faucet, a normal temperature water inlet pipe is usually arranged, so that the heating faucet also has the function of providing normal temperature water. The hot water inlet pipe and the normal temperature water inlet pipe are disposed on both sides of the central axis of the tap body housing in a first direction, and the first pipe body and the second pipe body of the return pipe may be disposed on both sides of the central axis of the tap body housing in a second direction perpendicular to the first direction. In this way, although the heating faucet can be made compact, the remaining space within the faucet body housing is scattered and dispersed and therefore is essentially unusable. Under the trend of miniaturization, the arrangement mode can not set other parts in the main faucet body shell, so that the function of the heating faucet is lost, and the requirements of modern people on multifunctional products can not be met.

At the same time, the normal temperature water inlet pipe can absorb the heat emitted by the hot water inlet pipe and the heat emitted by the second pipe body. In addition, the first pipe body, the second pipe body and the normal-temperature water inlet pipe can be guaranteed to be surrounded on the periphery of the hot water inlet pipe by the aid of the arrangement mode, heat emitted by the hot water inlet pipe is fully absorbed, and the heating effect of the main faucet body shell is better. The first pipe body is arranged close to the main faucet body shell, and the second pipe body is arranged far away from the main faucet body shell, so that the temperature rise of the main faucet body shell can be further controlled.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

According to one aspect of the present utility model, there is provided a heating faucet 10, as shown in fig. 1, the heating faucet 10 may include a faucet body 11 and a swivel arm 12. The bottom of the tap body 11 may be provided with a mounting seat 13, and the tap body 11 may be mounted to a desired location, such as a cabinet counter top, by the mounting seat 13. One end of the swivel arm 12 is rotatably connected to the tap body 11, for example, about a vertical axis. A hot water inlet pipe 120 is arranged in the tap body 11, a hot water outlet pipe 140 is arranged in the rotating arm 12, and the hot water outlet pipe 140 is connected between the hot water inlet pipe 120 and the water outlet nozzle 12 a. A heating assembly may be provided in or around the hot water inlet pipe 120 for heating the water therein. When the rotary arm 12 rotates relative to the tap main body 11, the position of the water outlet 12a can be adjusted, so that a user can conveniently receive water at different positions. Of course, the rotation axis of the swivel arm 12 may also be at an angle to the vertical. FIG. 2 is an exploded view of a heating faucet 10 according to an exemplary embodiment of the present utility model; fig. 3 is a schematic view assembled together, but with the tap body housing 110 of the tap body 11 and the housing of the swivel arm 12 removed to show the internal structure of the heating tap 10. Referring to fig. 1-3 in combination, a warm water inlet pipe 130 may also be provided in the faucet body 11, and a normal temperature water outlet pipe 150 may also be provided in the swivel arm 12. The heating faucet 10 thus has a function of supplying not only hot water but also warm water. In order to match the rotation of the rotating arm 12, the hot water inlet pipe 120 and the normal temperature water inlet pipe 130, the hot water outlet pipe 140 and the normal temperature water outlet pipe 150 may be connected through the waterway joint assembly 300, so that the hot water outlet pipe 140 and the normal temperature water outlet pipe 150 may rotate together with the rotating arm 12 when the rotating arm 12 rotates. Waterway adapter assembly 300 is described in greater detail below. Alternatively, the swivel arm 12 of the heating faucet 10 may be fixedly coupled to the faucet body 11, in which case the waterway adapter assembly 300 may be eliminated. In addition, the heating faucet 10 may not be provided with the normal temperature water inlet pipe 130 and the normal temperature water outlet pipe 150, and may be made inoperative when it is necessary to supply normal temperature water, whereby the same pipe may be used to supply hot water and normal temperature water.

As shown in fig. 1-2, the faucet body housing 110 has a central axis P-P extending in a longitudinal direction. In the illustrated embodiment, the faucet body housing 110 is generally cylindrical. Alternatively, the tap body housing 110 may have other shapes such as a prismatic shape, a horn shape with a thin upper portion and a thick lower portion, or a wavy shape in cross section through its central axis P-P, etc. The center axis P-P is a virtual axis, and serves as an auxiliary illustration, and is located at the center of the faucet body housing 110. The hot water inlet pipe 120 is provided in the tap body housing 110 and extends in a longitudinal direction. Typically, the hot water inlet pipe 120 is straight. However, in order to increase the heating area, the hot water inlet pipe 120 may also be in a spiral shape, in which case the hot water inlet pipe 120 extends in a longitudinal direction around its spiral center line, which direction is understood as the extending direction of the hot water inlet pipe 120. Furthermore, in the illustrated embodiment, the longitudinal direction is a vertical direction, but in other embodiments not shown, the longitudinal direction may be at an angle to the vertical direction.

A return tube 200 may be provided within the faucet body housing 110. The return pipe 200 includes a first pipe body 200a and a second pipe body 200b extending in a longitudinal direction. The first pipe body 200a and the second pipe body 200b are respectively arranged at two sides of the hot water inlet pipe 120, and the first pipe body 200a, the second pipe body 200b and the hot water inlet pipe 120 are connected end to end in sequence. Referring to fig. 3, the arrows therein illustrate the complete process of water heated via the hot water inlet tube 120 flowing within the heated faucet 10. As shown in fig. 4, the heating faucet 10 may include a heating body 410. The heating body 410 is located around the hot water inlet pipe 120 for heating the hot water inlet pipe 120. The hot water inlet pipe 120 is covered by the heating body 410 at the angle of fig. 3 and is not shown, but is marked with arrows at corresponding positions to facilitate understanding of the water flow direction. Specifically, water enters from the water inlet end a at the lower end of the heating faucet 10, enters the first tube 200a first, and then enters the second tube 200b from the upper end back to the bottom of the heating faucet 10. A diverter tab 440 may be provided at the bottom of the heating faucet 10 to redirect the flow of water therethrough. The steering joint 440 may connect the water outlet end of the second pipe body 200b with the water inlet end of the hot water inlet pipe 120. Water flowing out of the second pipe body 200b enters the hot water inlet pipe 120 through the steering joint 440. The water from the hot water inlet pipe 120 may enter the hot water outlet pipe 140 of the heating faucet 10 and flow out of the spout 12a of the heating faucet 10, see in combination figures 2-3. The hot water outlet pipe 140 is shielded by the normal temperature water outlet pipe 150 at the angle of fig. 3, so an arrow indicating the direction of water flow in the hot water outlet pipe 140 is placed above the normal temperature water outlet pipe 150.

Because the water needs to flow through the return pipe 200 before entering the hot water inlet pipe 120, the water in the return pipe 200 can absorb the heat emitted by the hot water inlet pipe 120, so that the temperature rise of the tap main body shell 110 can be controlled, and the safety of the tap during use is improved; but also preheats the water in the return pipe 200 to improve the energy utilization. Further, the return pipe 200 always stores water therein when the heating faucet 10 is stopped, and the heating faucet 10 is not dry-burned even if the water is stopped.

Fig. 4 shows the relative positions of the first pipe body 200a, the second pipe body 200b, and the hot water inlet pipe 120 with respect to the tap body housing 110. As shown in fig. 4, with respect to the above-mentioned central axis P-P, the hot water inlet pipe 120, the first pipe body 200a and the second pipe body 200b are all offset toward the same side S1 of the tap body housing 110. In order to distinguish this side from other sides, this side is referred to as a predetermined side S1. That is, the predetermined side S1 may be any side of the faucet body housing 110, particularly for axisymmetric geometries. By offsetting the hot water inlet pipe 120, the first pipe body 200a and the second pipe body 200b toward the same side S1, a large amount of surplus space can be left at the opposite side S2 to the side. In the illustrated embodiment, the predetermined side S1 is distinguished from the opposite side S2 by a line S-S. The hot water inlet pipe 120, the first pipe 200a and the second pipe 200b are entirely located in the predetermined side S1, but in the case that the pipes of the hot water inlet pipe 120, the first pipe 200a and the second pipe 200b themselves are thick or in the case that the inner diameter of the tap body housing 110 is small, one or more of the hot water inlet pipe 120, the first pipe 200a and the second pipe 200b may be disposed such that only the center thereof is located in the predetermined side S1 and a small portion thereof is located in the opposite side S2.

In the heating faucet 10 provided by the present application, the hot water inlet pipe 120, the first pipe body 200a and the second pipe body 200b are all offset toward a predetermined side of the faucet body housing 110, so that the space remaining in the other side of the faucet body housing 110 opposite to the predetermined side is relatively concentrated, so that there can be more choices in the utilization of the remaining space. For example, various electrical components may be installed in the remaining space of the faucet body housing 110, allowing for more functionality of the heating faucet 10. Not only meets the requirements of modern people on multifunctional products, but also does not cause the tap main body 11 to be too thick, and accords with the pursuit of people on miniaturized products. Illustratively, the outer diameter of the faucet body housing 110 is less than or equal to 50mm to conform to the trend of modern people for miniaturized products.

Illustratively, as shown in fig. 4, in the case where the heating faucet 10 includes the normal temperature water inlet pipe 130, one of the first and second pipe bodies 200a and 200b and the normal temperature water inlet pipe 130 are disposed at both sides of the central axis P-P, respectively. In the illustrated embodiment, the normal temperature water inlet pipe 130 is disposed opposite to the first pipe body 200a with respect to the central axis P-P. In an embodiment not shown, the normal temperature water inlet pipe 130 may be disposed opposite to the second pipe body 200b with respect to the central axis P-P. The principles of these two cases are similar and therefore the following description merely exemplifies illustrative embodiments to illustrate the principles of the application. The arrangement of the low temperature water inlet pipe 130 and the first pipe body 200a at both sides of the central axis P-P, respectively, includes one of the following cases: 1) In the cross section shown in fig. 4, the center P1 of the normal temperature water inlet pipe 130, the center P2 of the first pipe body 200a may be collinear with the point P representing the central axis P-P; 2) The line between P1 and P and the line between P2 and P may be at an angle other than 180 degrees, but for space saving, the angle is preferably greater than 160 degrees. In the second case, the included angle, whether toward the hot water inlet 120 or away from the hot water inlet 120, allows for a relatively concentrated arrangement of these lines on one side of the faucet body housing 110 and a sufficiently large remaining space on the other side. The choice of facing or facing away from the hot water inlet pipe 120 is also related to the structure and size of these components and can be chosen by one skilled in the art as desired. The first pipe body 200a, the second pipe body 200b, the hot water inlet pipe 120 and the normal temperature water inlet pipe 130 occupy substantially half of the space within the tap body housing 110 relatively intensively. Thus, the problem of space waste caused by the fact that the residual space in the tap main body housing 110 is not available due to the narrow space is solved. In the other half space remaining in the faucet body housing 110, elements that enrich the function of the heating faucet 10 can be added as needed, and because of the larger space there, the freedom of choice is greater, and there can be more free-standing when arranging elements.

Illustratively, as shown in fig. 2 and 3, the return pipe 200 may further include a U-shaped pipe body 200c connected between the water outlet end of the first pipe body 200a and the water inlet end of the second pipe body 200 b. As shown in fig. 4, the first and second pipe bodies 200a and 200b are respectively disposed at both sides of the hot water inlet pipe 120. By such arrangement, the first and second pipe bodies 200a and 200b can be ensured to absorb more heat emitted from the hot water inlet pipe 120, and the effect of controlling the temperature rise of the faucet body housing 110 is better. Fig. 3 generally shows the structure within faucet body housing 110 from a predetermined side. As shown in fig. 3, the U-shaped pipe body 200c may be inclined or bent toward a predetermined side with respect to the first and second pipe bodies 200a and 200 b. Referring to fig. 4 in combination, when the U-shaped tube 200c is bent toward the predetermined side S1, the space on the opposite side S2 is not occupied, so that the use of the remaining space in the faucet body housing 110 can be more selected, for example, corresponding elements can be provided according to different needs, and the elements can be electric elements, so that the heating faucet 10 can have more functions. It should be noted that the first tube 200a, the U-shaped tube 200c, and the second tube 200b are only names of different portions of the return tube 200. The first pipe body 200a, the U-shaped pipe body 200c and the second pipe body 200b are one pipeline, and are not required to be assembled when in use, so that the structure is not easy to leak water and is simple to install, and the time for heating the tap 10 in the production process is saved.

Illustratively, the space within the faucet body housing 110 may be divided into a first space and a second space by a virtual plane. The virtual plane may be defined by the longitudinal axis of the one of the first and second pipe bodies 200a and 200b (i.e., the one of the first and second pipe bodies 200a and 200b that is disposed on both sides of the central axis P-P with the normal-temperature water inlet pipe 130, respectively, and the longitudinal axis of the normal-temperature water inlet pipe 130 in the illustrated embodiment, the first pipe body 200 a). The virtual plane is the plane through line T-T and perpendicular to the paper surface in fig. 4. The spaces on both sides of the line T-T are a first space T1 and a second space T2, respectively. The other of the first and second pipes 200a and 200b (the second pipe 200b in the illustrated embodiment) and the hot water inlet pipe 120 are located in the first space T1.

As shown in connection with fig. 2-3, the heating faucet 10 may include a heating assembly 400 and electrical components. The heating assembly 400 is disposed around the hot water inlet pipe 120 for heating the hot water inlet pipe 120. The heating assembly 400 and the hot water inlet pipe 120 are located in the first space T1. The electrical element is located in the second space T2. Because the heating assembly 400 does not occupy the second space T2, the second space T2 is relatively large, and desired elements can be provided as needed, with greater freedom of choice. The electric element is arranged in the second space T2, so that the electric element can be selected more freely, and the heating faucet 10 can have more functions without increasing the outer diameter of the faucet main body shell 110 or the production cost, and simultaneously meets the requirements of modern people on multifunctional and miniaturized products. Moreover, when the electric element comprises an element which does not resist high temperature, the electric element can be further away from the heating assembly 400 and the hot water inlet pipe 120, and the electric element can be protected.

2-3, The electrical components may include one or more of a thermostat 160 and a wiring harness. The temperature controller 160 can monitor the operation condition of the heating assembly 400, and timely power off when the heating assembly 400 works abnormally, thereby protecting the heating faucet 10 and prolonging the service life of the heating faucet 10. Compared with the prior art, the heating faucet 10 provided by the application has the advantages that the residual space in the faucet main body shell 110 can be fully utilized, and the functions of the heating faucet 10 can be more diversified by selecting different electric elements. The concentrated placement of the electrical components in the second space T2 may be remote from the heating assembly 400 and the hot water inlet pipe 120, and may be avoided from being entangled with the pipeline for such electrical components as the wire harness, in addition to avoiding high temperatures affecting the life of the electrical components.

As previously described, where swivel arm 12 is rotatable relative to faucet body 11, heating faucet 10 may include waterway adapter assembly 300. As shown in fig. 2-3, waterway adapter assembly 300 may include waterway adapter 310. For a clearer understanding of the waterway adapter 310, the structure and assembly relationship of the waterway adapter 310 and the outlet rotator 320 coupled to the waterway adapter 310 will be further described. Referring to fig. 6 to 8, the waterway adapter 310 is provided with a hot water port 311 and a normal temperature water port 312. Waterway adapter 310 may include a first inner peripheral wall 313 and a first outer peripheral wall 314. The first inner peripheral wall 313 is inside the first outer peripheral wall 314, both being coaxial. The space formed by the first inner circumferential wall 313 communicates with the hot water port 311, thereby forming a first hot water passage 310A. The space surrounded by the first inner peripheral wall 313 and the first outer peripheral wall 314 communicates with the normal-temperature water joint 312, thereby forming a first normal-temperature water passage 310B. As shown in fig. 9 to 11, the water outlet rotator 320 may include a second inner circumferential wall 321 and a second outer circumferential wall 322. The second inner peripheral wall 321 is inside the second outer peripheral wall 322, and both are coaxial. The second inner circumferential wall 321 forms a water inlet of the second hot water passage 320A. The space surrounded by the second inner circumferential wall 321 and the second outer circumferential wall 322 forms a water inlet of the second normal-temperature water passage 320B. As shown in fig. 6 to 11, when the waterway adapter 310 is connected to the water outlet rotator 320, the first inner circumferential wall 313 and the second inner circumferential wall 321 may be sleeved and connected, so that the first hot water channel 310A is communicated with the second hot water channel 320A; the first outer circumferential wall 314 and the second outer circumferential wall 322 may be coupled so that the first ambient water channel 310B communicates with the second ambient water channel 320B. As shown in fig. 2 and 11, the water outlets of the second hot water channel 320A and the second normal temperature water channel 320B may be connected to the hot water outlet pipe 140 and the normal temperature water outlet pipe 150 of the heating faucet 10, respectively, to form a complete water flow channel. Optionally, a sealing ring may be disposed between the first inner circumferential wall 313 and the second inner circumferential wall 321, and a sealing ring may be disposed between the first outer circumferential wall 314 and the second outer circumferential wall 322, so as to further reduce the risk of water leakage. A quick connect fitting 330 may be provided on the water interface 312 as shown in fig. 2 and 5. The normal temperature water inlet pipe 130 may be connected to the quick connect fitting 330 to reduce the risk of water leakage and facilitate assembly. As shown in fig. 4, the minimum distance D1 between the normal temperature water inlet pipe 130 and the tap main body housing 110 may be greater than the minimum distance D2 between the one of the first pipe body 200a and the second pipe body 200b opposite to the normal temperature water inlet pipe 130 about the central axis P-P (the first pipe body 200a in the illustrated embodiment) and the tap main body housing 110.

In the heating faucet 10 provided in this embodiment of the present utility model, a large distance is provided between the normal temperature water inlet pipe 130 and the faucet body housing 110, and a small distance is provided between the body 200a or 200b opposite to the normal temperature water inlet pipe 130 with respect to the central axis P-P and the faucet body housing 110, whereby it is possible to secure a sufficient space for installing the quick connector 330 on the waterway adapter 310. The quick connector 330 has better water leakage prevention effect, thus protecting the electric elements in the heating faucet 10 and ensuring the safety of the heating faucet 10 in use.

Illustratively, as shown in FIG. 4, the minimum distance between the second tube 200b and the tap body housing 110 is greater than the minimum distance between the first tube 200a and the tap body housing 110. It is known that the water in the second pipe 200b is hotter than the water in the first pipe 200 a. Accordingly, the first tube 200a is disposed close to the main faucet body housing 110, and the second tube 200b is disposed away from the main faucet body housing 110, further controlling the temperature rise of the main faucet body housing 110.

Further, the normal temperature water inlet pipe 130 and the first pipe body 200a are disposed at both sides of the central axis P-P, respectively. The second pipe body 200b and the first pipe body 200a are respectively positioned at both sides of the hot water inlet pipe 120. The minimum distance D1 between the second tube 200b and the main faucet body housing 110 is greater than the minimum distance D2 between the first tube 200a and the main faucet body housing 110. As described above, the water in the first pipe 200a is lower in temperature than the water in the second pipe 200 b. To further control the temperature rise of the tap body housing 110, the first pipe body 200a having a low temperature may be disposed close to the tap body housing 110, and thus, the hot water inlet pipe 120 may be drawn toward the side where the first pipe body 200a is located, so that the distance between the second pipe body 200b and the tap body housing 110 may be greater than the distance between the first pipe body 200a and the tap body housing 110. Moreover, the above arrangement can ensure that the first pipe body 200a, the second pipe body 200b, the hot water inlet pipe 120 and the normal temperature water inlet pipe 130 are relatively compact, so that the remaining space in the faucet main body housing 110 is relatively concentrated, and more utilization possibilities can be provided. Meanwhile, the normal temperature water inlet pipe 130 may absorb heat emitted from the second pipe body 200b while absorbing heat emitted from the hot water inlet pipe 120. In addition, the above arrangement can ensure that the first pipe body 200a, the second pipe body 200b and the normal temperature water inlet pipe 130 are surrounded around the hot water inlet pipe 120, so that the heat emitted from the hot water inlet pipe 120 is fully absorbed, and the effect of controlling the temperature rise of the faucet main body housing 110 is better.

Illustratively, as shown in connection with fig. 2 and 12, the heating faucet 10 may further include a heating assembly 400 and a heating body upper end cap 430. The heating assembly 400 is disposed around the hot water inlet pipe 120 for heating water in the hot water inlet pipe 120. The hot water inlet pipe 120 is located within the heat transfer range of the heating element in the heating assembly 400. The heating body upper end cap 430 is connected to the top of the heating assembly 400. The heating body upper end cover 430 is provided with an adapter 431 and a first through hole 432. The transit connection 431 is connected between the hot water connection 311 (see fig. 5 and 7) and the hot water inlet pipe 120, and the normal temperature water inlet pipe 130 is connected to the quick connect coupling 330 through the first through hole 432. The first through hole 432 may be a relief for the normal temperature water inlet pipe 130. The adapter 431 increases the space between the heating body upper end cap 430 and the waterway adapter 310 while connecting the hot water interface 311 and the hot water inlet pipe 120, and provides a placement space for the quick connector 330.

Illustratively, as shown in connection with fig. 2 and 12-13, the water inlet end of the second tube body 200b extends between the heating body upper end cap 430 and the waterway adapter 310 through the first through hole 432. The first through hole 432 functions to fix the return pipe 200 by fixing the second pipe body 200 b.

Illustratively, the edge of the heating body upper end cover 430 is provided with a first relief notch 433, and the water outlet end of the first pipe body 200a extends between the heating body upper end cover 430 and the waterway adapter 310 through the first relief notch 433. The first abdication notch 433 can abdy the first tube 200a, so that the U-shaped tube 200c is located on the upper end cover 430 of the heating body, and the length of the return tube 200 can be increased, so that the U-shaped tube 200c can absorb the heat emitted from the adapter 431, and the temperature rise of the faucet main body housing 110 is avoided.

For example, as shown in connection with fig. 2 to 4 and 12, the second pipe body 200b may be adjacent to the normal temperature water inlet pipe 130. The return pipe 200 further includes a U-shaped pipe body 200c connected between the water outlet end of the first pipe body 200a and the water inlet end of the second pipe body 200 b. The U-shaped tube 200c is bent toward the predetermined side S1 to be positioned at the quick connector 330. Thereby, it is ensured that the quick coupler 330 can be mounted to the waterway adapter 310. The low temperature water inlet pipe 130 is closely adjacent to the second pipe body 200b, so that the space available in the tap body housing 110 becomes large. Meanwhile, the normal temperature water inlet pipe 130 can absorb heat emitted from the heating assembly 400 and the second pipe 200b at the same time, and has a better cooling effect on the tap main body housing 110.

Illustratively, as shown in connection with fig. 12-14, the heating assembly 400 may further include a heating body 410 and a heating body holder 420. The heating body 410 as the heating element of the heating assembly 400 may include various types of heating bodies such as thick film heating bodies, electromagnetic heating bodies, and the like. The heating body holder 420 has a cavity Q extending in the longitudinal direction. The heating body 410 is placed in the cavity Q, and a safety distance is designed between the heating body 410 and the heating body bracket 420, and the safety distance can be 2-5mm. This distance prevents electrification of the housing of the tap body 11 caused by current breakdown. Nor is the stand 220 too thick due to too great a distance. Solves the problems of inconsistent products and limited installation. The first tube body 200a, the second tube body 200b, and the normal temperature water inlet tube 130 are fixed on the outer side surface of the heating body bracket 420. The first pipe body 200a, the second pipe body 200b and the normal temperature water inlet pipe 130 can absorb heat released from the heating assembly 400 at the same time, and the effect of controlling the temperature rise of the tap body housing 110 is better.

In embodiments where the heating body 410 is a plurality of, the heating body 410 may continuously or discretely surround the hot water inlet tube 120. Alternatively, one or more heating bodies 410 may also semi-surround the hot water inlet pipe 120. "semi-surrounding" includes surrounding one-half, more than one-half, or less than one-half of the circumference of the hot water inlet pipe 120. That is, the heating body 410 may be provided at a side of the hot water inlet pipe 120 to locally heat the hot water inlet pipe 120. Alternatively, the heating body 410 may be closely attached to the hot water inlet pipe 120 or may not be in direct contact with the hot water inlet pipe 120, and may be spaced apart from each other by a certain distance. In general, the hot water inlet pipe 120 is only required to be within the heat transfer range of the heating body 410.
