[0033] Combined with reference Figures 1 to 3 , Figure 5, the heating assembly 1 may include a tank body 10 and a heating element 20. The tank body 10 may have a first body 110 and a second body 120. The first body 110 may be enclosed to form an installation cavity 130. A water storage cavity 140 may be formed between the second body 120 and the first body 110. A connecting hole 111 may be provided on the first body 110. The installation cavity 130 and the water storage cavity 140 may be connected through the connecting hole 111. A first water inlet 121 and a first water outlet 122 may be provided on the second body 120. The heating element 20 may be arranged in the installation cavity 130, and a second water inlet 210 and a second water outlet 220 may be provided on the heating element 20. Among them, the first water inlet 121 may be connected to the outside. The first water outlet 122 may be selectively connected to the second water inlet 210. The second water outlet 220 may be connected to the outside.

[0034] In the heating assembly 1 of the present invention, on the one hand, the heating element 20 is arranged in the installation cavity 130 and is integrated with the tank body 10, which not only occupies less space but also reduces costs; on the other hand, when the first water outlet 122 and the second water inlet 210 are connected, water can enter the heating element 20 from the first water outlet 122 through the second water inlet 210 to be heated, and then flow out from the second water outlet 220, and the heating efficiency is high; when the connection between the first water outlet 122 and the second water inlet 210 is disconnected, the heating element 20 increases the water temperature of the water storage cavity 140 based on heat conduction, thereby meeting the user's demand for a large amount of hot water.

[0035] In one embodiment of the present invention, refer to Figure 3 , the second body 120 may include a side body 123, a first connecting body 124, and a second connecting body 125. The side body 123 may be arranged around the outside of the first body 110 and concentrically with the first body 110, and the central axis of the side body 123 may be coaxial with the central axis of the first body 110. The first connecting body 124 and the second connecting body 125 may be opposite, and the first connecting body 124 and the second connecting body 125 may be connected between the side body 123 and the first body 110. That is, the first connecting body 124 may be connected to one end of the side body 123 and the first body 110, and the second connecting body 125 may be connected to the other end of the side body 123 and the first body 110. The side body 123, the first connecting body 124, the second connecting body 125 and the first body 110 may be enclosed to form the installation cavity 130. With such an arrangement, the tank body 10 has a simple structure and is conducive to forming the water storage cavity 140.

[0036] In one embodiment of the present utility model, in conjunction with reference to Figure 2 and Figure 3, the first water inlet 121 can be arranged on the first connecting body 124. The first water outlet 122 can be arranged on the second connecting body 125. In this way, the first water inlet 121 and the first water outlet 122 are respectively arranged on two opposite connecting bodies, which can facilitate the first water inlet 121 and the first water outlet 122 to connect their respective corresponding pipelines. The first connecting body 124 can be connected to a first water inlet pipe 127, and the first water inlet pipe 127 can pass through the first water inlet 121 and extend into the water storage chamber 140. The first water inlet pipe 127 can have a first water inlet end 1271 and a first water outlet end 1272. The first water inlet end 1271 can be located outside the water storage chamber 140, which is more convenient to connect with the pipeline. The first water outlet end 1272 can be located inside the water storage chamber 140, and the first water outlet end 1272 can be closer to the second connecting body 125 than the first connecting body 124. After the heating assembly 1 is installed, in the vertical direction, when the first connector 124 faces upward and the second connector 125 faces downward, low-temperature water can flow smoothly to prevent low-temperature water from splashing in the water storage chamber 140 and affecting the preheated water. The second connector 125 can be connected to a first water outlet pipe 128, and the first water outlet pipe 128 can pass through the first water outlet 122 and extend into the water storage chamber 140. The first water outlet pipe 128 can have a second water inlet end 1281 and a second water outlet end 1282. The second water inlet end 1281 can be located outside the water storage chamber 140, which is more convenient for connection with the pipeline. The second water outlet end 1282 can be located inside the water storage chamber 140, and the second water outlet end 1282 can be closer to the first connector 124 than the second connector 125. In this way, after the heating component 1 is installed, in the vertical direction, when the first connector 124 faces upward and the second connector 125 faces downward, the second water outlet 1282 and the second water inlet 210 are connected, which is beneficial for preheating the water in the water storage chamber 140 before flowing out.

[0037] In one embodiment of the present invention, again in conjunction with reference to Figure 2 and Figure 3 , the first connector 124 may be provided with an exhaust port 126. The exhaust port 126 may have an exhaust pipe 1261 extending outwardly, so as to be conveniently connected to the pipeline. After the heating assembly 1 is installed, in the vertical direction, when the first connector 124 faces upward and the second connector 125 faces downward, the exhaust port 126 may be located at the top of the water storage chamber 140. Such a configuration can avoid problems such as leakage caused by excessive air pressure in the water storage chamber 140 or bursting of the tank body 10.

[0038] In one embodiment of the present invention, refer to Figure 1, the second body 120 may be provided with an exhaust port 126. The exhaust port 126 may have an exhaust pipe 1261 extending outwardly, which is convenient for connection with the pipeline. After the heating assembly 1 is installed, in the vertical direction, in order to prevent water from entering the exhaust port 126 and affecting the exhaust effect, the exhaust port 126 may be higher than the first water outlet 122. Such a configuration can avoid problems such as leakage caused by excessive air pressure in the water storage chamber 140 or bursting of the tank body 10.

[0039] In one embodiment of the present utility model, in conjunction with reference to Figure 3 , Figure 5 and Figure 6 , the heating element 20 may include a tube body 230 and a heating body 240. The heating body 240 may be arranged in the tube body 230. The heating body 240 may be an infrared heating body or a resistance heating body, etc. The tube body 230 may be a glass tube or a metal tube, etc. When the heating body 240 is an infrared heating body, the heating effect of the tube body 230 using a glass tube is the best, and the light emitted by the infrared heating body can penetrate the glass tube, thereby heating the water outside the glass tube. There may be a gap between the tube body 230 and the first body 110. Water can enter the gap through the connecting hole 111. In this way, when in use, the gap can be filled with water. When the connection between the first water outlet 122 and the second water inlet 210 is disconnected, the water in the gap is first heated by the heating element 20, and then the water temperature of the water storage chamber 140 is increased based on the heat conduction effect, thereby improving the heating efficiency.

[0040] Combined with reference Figure 3 and Figure 4 , the connecting hole 111 may have one or more, and as the number of connecting holes 111 increases and the area increases, the amount of water exchanged between the installation chamber 130 and the water storage chamber 140 increases per unit time. The connecting holes 111 may have four, two connecting holes 111 may be arranged near the first connecting body 124, and the two connecting holes 111 are respectively facing the first water inlet pipe 127 and the first water outlet pipe 128; the two connecting holes 111 may be arranged near the second connecting body 125, and the two connecting holes 111 are also respectively facing the first water inlet pipe 127 and the first water outlet pipe 128. In this way, it is convenient for the low-temperature water flowing out of the first water inlet pipe 127 to enter the installation chamber 130, and it is convenient for the water preheated in the installation chamber 130 to flow out to the first water outlet pipe 128. The area of ​​the two connecting holes 111 near the first connecting body 124 may be larger than the area of ​​the two connecting holes 111 near the second connecting body 125. It is avoided that too much low-temperature water enters the installation chamber 130, which causes great interference to the preheated water.

[0041] In one embodiment of the present utility model, in conjunction with reference to Figure 3 , Figure 5 , Figure 6 and Figure 7, the first body 110 may have a first connection portion 112 disposed near the first connection body 124 and a second connection portion 113 disposed near the second connection body 125. The tube body 230 may have a first end 231 and a second end 232. The first end 231 and the first connection portion 112 may be connected via a first end cap 31, and the second end 232 and the second connection portion 113 may be connected via a second end cap 32. It is convenient to install and disassemble the heating element 20, and it is convenient to clean and repair the heating element 20. The first end cap 31 and the second end cap 32 may at least partially protrude from the outside of the installation cavity 130, the heating body 240 may be connected to the second end cap 32, and the heating body 240 may partially pass through the second end cap 32, so that the heating body 240 is conveniently connected to the external circuit, and the circuit is prevented from being damaged by contact with water. In this way, the first body 110, the tube body 230, the first end cap 31 and the second end cap 32 may enclose a water storage space 40.

[0042] In one embodiment of the present utility model, in conjunction with reference to Figure 6 and Figure 7 A first sealing member 51 may be sandwiched between the first end cap 31 and the first end 231. The first sealing member 51 may be made of rubber or silicone material. The shape of the first sealing member 51 may be similar to that of the first end cap 31, so that the first sealing member 51 and the first end cap 31 can fit more closely. This arrangement prevents hot water from flowing out of the gap between the tube body 230 and the first end cap 31, affecting the operation of other structural parts.

[0043] In one embodiment of the present utility model, in conjunction with reference to Figure 3 , Figure 6 and Figure 7 A second sealing member 52 may be sandwiched between the second end cover 32 and the second end 232. The second sealing member 52 may be made of rubber material or silicone material, etc. The shape of the second sealing member 52 may be similar to the shape of the second end cover 32, so that the second sealing member 52 and the second end cover 32 may fit more closely. The second sealing member 52 has an extension portion 521, and the extension portion 521 is sandwiched between the heating body 240 and the second end cover 32, so as to prevent the water in the water storage space 40 from damaging the part of the heating body 240 connected to the circuit. This arrangement prevents hot water from flowing out of the gap between the tube body 230 and the second end cover 32, thereby affecting the operation of other structural parts.

[0044] In one embodiment of the present utility model, in conjunction with reference to Figure 3 and Figure 6 A temperature sensor 60 may be provided on the first end cover 31. By providing the temperature sensor 60, the temperature of the water may be measured. When the temperature reaches the set temperature, the heating body 240 may stop heating to avoid safety hazards caused by excessively high water temperature.

[0045] In one embodiment of the present utility model, in conjunction with reference to Figure 3 and Figure 5 , the second water inlet 210 can be arranged on the second end cover 32. In this way, the distance between the first water outlet 122 and the second water inlet 210 is close, which is convenient for connection, and the distance between the first water inlet 121 and the second water inlet 210 is far, which is conducive to temperature control, and avoids the low-temperature water entering the first water inlet 121 directly entering the heating element 20 through the second water inlet 210, thereby interfering with the temperature of the water in the heating element 20.

[0046] In one embodiment of the present invention, refer to Figure 6 The second water outlet 220 can be arranged on the first end cover 31. Such arrangement can facilitate the second water outlet 220 to be connected to the outside.

[0047] Combined with reference Figures 1 to 7After the heating component 1 is installed, in the vertical direction, the first connecting body 124 faces upward, and the second connecting body 125 faces downward. The working process of the heating component 1 in this case is described in detail. When the second water outlet 1282 is connected to the second water inlet 210 (that is, the heating component 1 is in the starting state), low-temperature water enters the first water inlet end 1271 from the outside, flows from the first water inlet end 1271 through the first water inlet pipe 127 and enters the water storage chamber 140 through the first water outlet end 1272, and water enters the water storage chamber 140 from the connecting hole 111. The heat emitted by the heating body 240 is input into the installation cavity 130, and the water temperature in the installation cavity 130 can be increased based on the effect of heat conduction. The heated water in the installation cavity 130 is continuously exchanged with the low-temperature water in the water storage cavity 140, so that the water temperature in the water storage cavity 140 is increased. When the water temperature is increased, steam is generated, and the steam can be discharged from the exhaust port 126. However, the heat emitted by the heating body 240 is less after penetrating the tube body 230, and the amount of low-temperature water is continuously increasing. Therefore, it is difficult for the water temperature to reach the predetermined temperature, but the water can be preheated to a certain extent. The preheated water flows through the second water inlet end 1281 through the first water outlet pipe 128 and flows out from the second water outlet end 1282, then flows through the pipe connected between the second water outlet end 1282 and the second water inlet 210, and then flows into the pipe body 230 from the second water inlet 210. After being further heated by the heating body 240, the water temperature reaches a predetermined temperature. After the temperature sensor 60 measures that the water temperature has reached the predetermined temperature, the heating body 240 stops heating, and the water that has reached the predetermined temperature finally flows to the outside from the second water outlet 220. When the connection between the second water outlet 1282 and the second water inlet 210 is disconnected (i.e., the heating component 1 is in standby mode), the heating body 240 is heated at low power, and the water in the water storage chamber 140 enters the installation chamber 130 through the connecting hole 111. Based on the heat conduction effect, the water temperature in the installation chamber 130 can be increased. The heated water in the installation chamber 130 is continuously exchanged with the low-temperature water in the water storage chamber 140, so that the water temperature in the water storage chamber 140 is increased, thereby storing heat.

[0048] According to another aspect of the present invention, a water dispenser is provided, which may include a body and the heating assembly 1 as described above. The heating assembly 1 may be arranged on the body. The water dispenser of the present invention includes the heating assembly 1 as described above. Since the heating assembly 1 as described above has the beneficial effects as described above, the water dispenser including the heating assembly 1 as described above must also have the beneficial effects as described above.
