Referring to fig. 1 to 8, an embodiment of the present disclosure provides a water heater, which includes a heating device and a water pipe 200; the heating device comprises a heating source 400 and a heating pipeline 100, and the heating device is connected with the heating source 400; the water pipeline 200 comprises a water inlet end 211 and a water outlet end 231; the water passage 200 exchanges heat with the heating passage 100 to heat water flowing through the water passage 200.

By adopting the water heater provided by the embodiment of the present disclosure, the heat exchange medium flowing through the heating pipeline 100 can be heated by the heating source 400, and heat exchange is performed between the water pipeline 200 and the heating pipeline 100, so that heating of water flowing through the water pipeline 200 is realized. Thus, tap water enters the water pipe 200 through the water inlet end 211, is heated in the water pipe 200, and is discharged from the water outlet end 231; in the process, the tap water flowing through the water passage 200 can be heated without direct contact between the heating source 400 and the tap water; even if the water heater is used for a long time, no scale deposit is generated on the heating source 400, thereby ensuring the heating effect of the water heater.

Herein, the water passage 200 and the heating passage 100 are not communicated with each other. That is, the heat exchange medium in the heating line 100 cannot enter the water flow line 200, and the water in the water flow line 200 cannot enter the heating line 100. Here, the water passage line 200 and the heating line 100 may exchange heat in various manners, for example, the water passage line 200 and the heating line 100 exchange heat by contact, or the water passage line 200 and the heating line 100 exchange heat through the phase change material 300.

Alternatively, the water passage line 200 exchanges heat with the heating line 100 through contact. Thus, the water pipe 200 and the heating pipe 100 do not need to be filled with other heat exchange media, and the two exchange heat through contact, so that the direct contact between the heating source 400 and tap water is not needed, and the heating effect on water flowing through the water pipe 200 can be realized; in addition, since the water in the water pipe 200 enters the heating pipe 100, even if the water heater is used for a long time, no scale is deposited on the heating source 400, and the heating effect of the water heater is not affected.

Alternatively, the water passage pipe 200 is wound around the heating pipe 100. When the heating pipes 100 are equal in length, the water pipe 200 is wound around the heating pipe 100, so that the contact area between the water pipe 200 and the heating pipe 100 can be increased, the heat exchange between the water pipe 200 and the heating pipe 100 can be more sufficient, and the heating effect of the water heater can be improved.

Optionally, the water passage pipe 200 is inserted into the heating pipe 100. The water pipeline 200 may be completely inserted into the heating pipeline 100, or partially inserted into the heating pipeline 100, so that the heat exchange medium in the heating pipeline 100 wraps the water pipeline 200, and the heat exchange between the water pipeline 200 and the heating pipeline 100 is more sufficient, thereby improving the heating effect of the water heater.

Alternatively, the water passage line 200 exchanges heat with the heating line 100 through the phase change material 300. In this way, the heating line 100 absorbs heat from the heating source 400 and transfers the heat to the phase change material 300 in such a manner that the water passage line 200 and the heating line 100 exchange heat through the phase change material 300, and the water passage line 200 absorbs heat of the phase change material 300 to heat water flowing through the water passage line 200 while the water passage line 200 is flowing water. In this way, the heat source 400 does not directly contact the heated tap water, but the heat from the heat source 400 is absorbed and stored by the phase change material 300, and when the water passage 200 passes water having a low temperature, the water passage 200 absorbs the heat stored in the phase change material 300, thereby heating the water in the water passage 200. The phase change material 300 has a characteristic of storing heat, so that loss of heat in a heat exchange process can be reduced, thereby improving heat exchange efficiency.

Optionally, the heating line 100 is disposed through the phase change material 300. The heating pipes 100 include one or more groups, and each group of heating pipes 100 penetrates through the phase change material 300 and exchanges heat with the phase change material 300.

The first heating branch and the second heating branch are two adjacent heating branches 110.

Optionally, the water pipeline 200 is disposed through the phase change material 300 and spaced apart from the heating pipeline 100. The water passage line 200 may be spaced apart from the heating line 100, which means that the water passage line 200 is not in contact with the heating line 100. The water pipeline 200 and the heating pipeline 100 are both arranged through the phase change material 300, and the phase change material 300 is arranged between the water pipeline 200 and the heating pipeline 100 as a heat exchange medium.

Optionally, the water pipeline 200 includes a water inlet main line 210, a water passage branch line 220, and a water outlet main line 230, and the water inlet main line 210, the water passage branch line 220, and the water outlet main line 230 are all disposed through the phase change material 300. Wherein, the water branch 220 comprises a plurality of water branches, each water branch 220 comprises a water inlet 221 and a water outlet 222; each water inlet 221 is communicated with the water inlet main path 210; each water outlet 222 is communicated with a water outlet main 230. In this way, the water flowing branches 220 are connected in parallel, so that the water in the water inlet main line 210 can flow into different water flowing branches 220 for heat exchange, and then the water after heat exchange is collected in the water outlet main line 230, and the water in the water outlet main line 230 can flow to the water outlet end 231 of the water flowing pipeline 200.

Optionally, a plurality of water passing branches 220 are uniformly distributed along the axial direction, so that the heat exchange between the water passing branches 220 and the phase change material 300 is sufficient, and the energy utilization rate of the water heater is improved.

Optionally, the water passage branch 220 comprises a first coil 223 and a second coil 224, the first coil 223 and the second coil 224 are coaxially arranged, and the first coil 223 is parallel to the second coil 224. Wherein, one end of the first coil 223 near the axial center is communicated with one end of the second coil 224 near the axial center. One end of the first coil 223 far away from the axis can be used as a first end of the water branch 220, and one end of the second coil 224 far away from the axis can be used as a second end of the water branch 220; similarly, the end of the second coil 224 away from the axial center may be the first end of the water passage branch 220, and the end of the first coil 223 away from the axial center may be the second end of the water passage branch 220. The water in the water inlet main 210 enters the water passage branch 220 through the first end, and then flows out of the water passage branch 220 through the second end, and then flows to the water outlet main 230.

Optionally, the water heater further comprises a shell 310, and the phase change material 300 is filled in the shell 310.

Alternatively, the phase change material 300 includes an organic phase change material and an inorganic phase change material, and the phase change material 300 has the ability to change its physical state within a certain temperature range. For example, a phase change material 300 that transitions between a solid state and a liquid state, upon heating the phase change material 300 to a melting temperature, produces a phase change from the solid state to the liquid state, during which the phase change material 300 absorbs and stores heat; when the temperature of the phase-change material 300 is lowered, the stored heat can be transferred to the water pipe 200 or the air within a certain temperature range, and the phase-change material 300 changes from a liquid state to a solid state to realize the heat transfer.

Therefore, the phase change material 300 can be sealed in the shell 310, heat exchange between the phase change material 300 and the surrounding environment can be reduced, and the energy storage effect of the phase change material 300 is improved.
