Technical Field

[0001] This application belongs to the technical field of electrical equipment, and particularly relates to a heating component and a water heater. Background Art

[0002] Heating components are widely used in different electrical appliances and can play a heating role. When a heating component heats a liquid, it can heat the normal-temperature liquid to the temperature required by the user. However, during the heating process, phenomena such as uneven temperature inside the pipe may occur. Utility Model Content

[0003] This application aims to at least solve the technical problem that the heating component is easily damaged to a certain extent. For this reason, this application provides a heating component and a water heater.

[0007] A water outlet pipe communicated with the first water outlet.

[0008] The axis of the first connecting pipe being arranged offset from the axis of the heating pipe means that the axis of the first connecting pipe does not pass through the axis of the heating pipe. That is, it can be considered that the first connecting pipe is eccentrically arranged on the heating pipe. The axis of the first connecting pipe can also represent the flow direction of the water flow into the heating pipe, that is, the water outlet direction of the first connecting pipe. When the axis of the first connecting pipe is arranged offset from the axis of the heating pipe, it means that the water flow entering the heating pipe from the first connecting pipe will not pass through the axis of the heating pipe and will collide with the inner wall of the heating pipe, thereby forming a spiral water path inside the heating pipe, which can realize the full mixing of the liquid in the heating pipe, make the outlet water temperature uniform. In addition, it increases the flow path of the water flow in the heating pipe, increases the heat exchange time between the water flow and the heating pipe, can effectively take away the heat on the surface of the heating pipe, improves the heat exchange efficiency, reduces the heat density when the heating pipe works, and can extend the service life of the heating pipe and reduce the failure rate of the heating pipe.

[0009] In some embodiments of this application, the heating pipe includes a shell and a cover body connected to the shell. The first water inlet is arranged on the cover body, the first water outlet is arranged on the shell, and the first connecting pipe is connected to the cover body.

[0010] In some embodiments of the present application, the cover body and the first connecting pipe are integrally formed.

[0011] In some embodiments of the present application, the first connecting pipe is a straight pipe, and the extending direction of the straight pipe is tangent to the inner wall surface of the cover body.

[0012] In some embodiments of the present application, the heating pipes, the first connecting pipes, and the second water outlets are respectively multiple and correspond one by one. The multiple second water outlets are arranged in sequence in the direction away from the second water inlet. One first connecting pipe communicates with one second water outlet and one heating pipe respectively.

[0013] In some embodiments of the present application, along the flow path direction away from the second water inlet, the opening areas of the multiple first connecting pipes decrease in sequence.

[0014] In some embodiments of the present application, the multiple second water outlets are at the same height.

[0015] In some embodiments of the present application, the multiple first connecting pipes are at the same height.

[0016] In some embodiments of the present application, the first water outlets of the multiple heating pipes are connected and communicated in sequence, and the first water outlet of one of the heating pipes is directly communicated with the water outlet pipe.

[0017] In some embodiments of the present application, the first water inlet is located at the bottom of the heating pipe, and the first water outlet is located at the top of the heating pipe.

[0018] In some embodiments of the present application, the heating assembly includes a fixing member, and the fixing member fixedly connects the multiple heating pipes; or the fixing member fixedly connects the multiple heating pipes and the water inlet pipe; or the fixing member fixedly connects the multiple heating pipes and the water outlet pipe.

[0019] In some embodiments of the present application, the first connecting pipe is perpendicular to the water inlet pipe.

[0020] In a second aspect, an embodiment of the present application provides a water heater, including the above-mentioned heating assembly.

[0021] The beneficial effects of the water heater provided in the second aspect are the same as those of the heating assembly provided in the first aspect, and will not be elaborated here. Description of the Drawings

[0041] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0042] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, a heating component 100 is provided. The heating component 100 provided in the embodiment of the present application can be applied to heating devices such as water heaters and water dispensers. The heating component 100 provided in the embodiment of the present application can heat more water in the same time and improve the water output.

[0043] In the embodiment of the present application, for the convenience of description, the heating of water by the heating component 100 is taken as an example for elaboration. When the heating component 100 heats other liquids or gases, it can be deduced by analogy. Among them, the temperature of the water in the water outlet pipe 130 is greater than or equal to the temperature of the water in the water inlet pipe 110. In order to distinguish water at different temperatures, the water in the water inlet pipe 110 is defined as cold water, and the water in the water outlet pipe 130 is defined as hot water.

[0044] In the embodiment of the present application, the heating component 100 includes: a water inlet pipe 110, a water outlet pipe 130, and a plurality of heating pipes 120. The water inlet pipe 110 has a second water inlet 112 and a second water outlet 114; the heating pipe 120 has a first water inlet 121a and a first water outlet 121b which are oppositely arranged. The first water inlets 121a of the plurality of heating pipes 120 are connected and communicated in sequence, and one of the first water inlets 121a is communicated with the second water inlet 112; the water outlet pipe 130 and the water inlet pipe 110 are respectively arranged at both ends of the plurality of heating pipes 120. The water outlet pipe 130 has a third water outlet 132 and a third water inlet 134, and the third water inlet 134 is communicated with the first water outlet 121b.

[0045] The second water inlet 112 of the water inlet pipe 110 is used to connect to a water source to divert external cold water into the entire heating component 100, so that the heating component 100 can heat the cold water into hot water. The third water outlet 132 of the water outlet pipe 130 is used to connect to an external usage end to output the hot water heated by the heating component 100 outside the heating component 100 for users to use.

[0046] In the embodiment of the present application, the heating tube 120 is the main device for heating the entire heating assembly 100. After the cold water in the water inlet pipe 110 enters the heating tube 120, it flows out from the water outlet pipe 130 after being heated by the heating tube 120. The cold water flows along the extension direction of the heating tube 120 after entering the heating tube 120, and finally flows out from the water outlet pipe 130 after being heated at different positions of the heating tube 120.

[0047] The water inlet pipe 110 is a strip-shaped through pipe. The second water inlet 112 of the water inlet pipe 110 is communicated with an external water source, and the second water outlet 114 of the water inlet pipe 110 is communicated with the first water inlet 121a, so as to divert the external cold water into the entire heating assembly 100, enabling the heating assembly 100 to heat the cold water into hot water. The third water inlet 131a of the water outlet pipe 130 is communicated with the first water outlet 121b, and the third water outlet 131b of the water outlet pipe 130 is used to connect with an external usage end, so as to output the hot water heated by the heating assembly 100 outside the heating assembly 100 for users to use.

[0048] Among them, the heating tube 120 is generally in a long strip shape. The first water inlet 121a and the first water outlet 121b are respectively two different ends of the heating tube 120. The temperature of the hot water flowing out from the first water outlet 121b is related to both the length and power of the heating tube 120. When the power of the heating tube 120 is the same, the longer the heating tube 120, the higher the temperature of the hot water entering the water outlet pipe 130. On the contrary, the shorter the heating tube 120, the lower the temperature of the hot water entering the water outlet pipe 130. Similarly, when the length of the heating tube 120 is the same, the higher the power, the higher the temperature of the hot water entering the water outlet pipe 130. On the contrary, the lower the power, the lower the temperature of the hot water entering the water outlet pipe 130. The length and power of the heating tube 120 can be set according to the working requirements of the entire heating assembly 100 to meet the hot water demand.

[0049] In the embodiment of the present application, the water outlet pipe 130 is communicated with the heating tube 120. It can be considered that the water outlet pipe 130 and the heating tube 120 form a communicating vessel. After the hot water in the heating tube 120 enters the water outlet pipe 130, it needs to pass through the highest point in the water outlet pipe 130 before flowing out from the water outlet pipe 130.

[0050] The axis of the first connecting pipe 140 is arranged offset from the axis of the heating pipe 120, which means that the axis of the first connecting pipe 140 does not pass through the axis of the heating pipe 120. That is, it can be considered that the first connecting pipe 140 is eccentrically arranged on the heating pipe 120. The axis of the first connecting pipe 140 can also represent the flow direction of the water flow into the heating pipe 120, that is, the water outlet direction of the first connecting pipe 140. The axis of the first connecting pipe 140 is arranged offset from the axis of the heating pipe 120, which means that the water flow entering the heating pipe 120 from the first connecting pipe 140 will not pass through the axis of the heating pipe 120 and will collide with the inner wall of the heating pipe 120, thereby forming a spiral water path inside the heating pipe 120. This can achieve the full mixing of the liquid in the heating pipe 120, make the outlet water temperature uniform. In addition, it increases the flow path of the water flow in the heating pipe 120 and the heat exchange time between the water flow and the heating pipe 120, can effectively take away the heat on the surface of the heating pipe 120, improve the heat exchange efficiency, reduce the heat density when the heating pipe 120 works, and can extend the service life of the heating pipe 120 and reduce the failure rate of the heating pipe 120.

[0051] At the same time, the water flow forms a spiral water path inside the heating pipe 120, which can increase the flow path of the water flow in the heating pipe 120, increase the heat exchange time between the water flow and the heating pipe 120, make full use of the heat of the heating pipe 120, and enable the water flow to reach the target temperature value when flowing out of the heating pipe 120 from the first water outlet 121b, improving the heating effect of the entire heating assembly 100.

[0052] In some embodiments, the heating pipe 120 includes a housing 122 and a cover 128 connected to the housing 122. The first water inlet 121a is arranged on the cover 128, the first water outlet 121b is arranged on the housing 122, and the first connecting pipe 140 is connected to the cover 128.

[0053] Among them, the housing 122 and the cover 128 are of a split structure. The cover 128 is arranged at the end of the housing 122. The cover 128 can be connected to the housing 122 by means of threads. Components such as the heating member are mainly installed inside the housing 122. If a failure occurs in the heating member inside the housing 122 or if there is a blockage inside the housing 122, the cover 128 can be detached from the housing 122 to facilitate the repair of the components inside the housing 122.

[0054] In some embodiments, the cover 128 and the first connecting tube 140 are integrally formed. They can be integrally formed by welding or the like. The first connecting tube 140 is mainly used to connect the water inlet pipe 110 and the heating tube 120. The first connecting tube 140 and the cover 128 are integrally formed, which means that the first connecting tube 140 and the cover 128 are an integrated structure, which can reduce the assembly process between the first connecting tube 140 and the cover 128 and facilitate assembly. At the same time, the risk of leakage between the first connecting tube 140 and the cover 128 can also be avoided.

[0055] In some embodiments, the first connecting tube 140 is a straight tube, and the extension direction of the straight tube is tangent to the inner wall surface of the cover body 128. The interior of the cover body 128 is a hollow structure, and the extension direction of the first connecting tube 140 is not tangent to the interior of the cover body 128, which means that the water inlet direction in the first connecting tube 140 is tangent to the inner wall surface of the cover body 128, which means that the flow direction of the first connecting tube 140 entering the heating tube 120 is farthest from the axis of the heating tube 120. When the water flows from the first connecting tube 140 into the cover body 128, the path of the spiral waterway formed in the entire heating tube 120 is large, and the water flows in the heating tube 120 for a long time, which can increase the heat exchange time between the water flow and the heating tube 120 as much as possible, can effectively take away the heat on the surface of the heating tube 120, reduce the heat density of the heating tube 120 when working, can extend the service life of the heating tube 120 and reduce the failure rate of the heating tube 120. The heat of the heating pipe 120 is fully utilized so that the water can reach the target temperature when flowing out of the heating pipe 120 from the first water outlet 121 b, thereby improving the heating effect of the entire heating component 100 .

[0056] In addition, when water flows from the first connecting pipe 140 into the cover body 128, a vortex can be formed in the heating pipe 120 during the upward flow of the water, which can fully mix the water in the heating pipe 120 and make the temperature of the water relatively uniform. In some embodiments, along the flow path direction away from the second water inlet 112, the opening area of the water inlet pipe 110 decreases in sequence. Herein, the flow path direction refers to the water flow direction in the water inlet pipe 110. There are multiple heating pipes 120, first connecting pipes 140, and second water outlets 114, and they are in one-to-one correspondence. The water inlet pipe 110 is respectively connected to different heating pipes 120 through different first connecting pipes 140. That is, multiple first connecting pipes 140 are sequentially arranged on the water inlet pipe 110. In the direction of the water inlet pipe 110 from the second water inlet 112 to the second water outlet 114, the water inlet pipe 110 needs to supply water to different heating pipes 120. The water flow through the first first connecting pipe 140 needs to supply water to the first heating pipe 120 and all the subsequent heating pipes 120. In order to ensure that the heating water volume of each heating pipe 120 is as the same as possible, the opening area of the water inlet pipe 110 closer to the second water inlet 112 should be larger to ensure that the water volume of the subsequent heating pipes 120 can be approximately the same.

[0057] For example: there are three heating pipes 120 in total and also three first connecting pipes 140. The rightmost heating pipe 120 is the closest to the second water inlet 112. The three heating pipes 120 from right to left are numbered 1, 2, and 3 in sequence. Similarly, the first connecting pipes 140 connected to the three heating pipes 120 from right to left are also numbered 1, 2, and 3 in sequence. In the water inlet pipe 110, the water volume flowing through the first first connecting pipe 140 needs to supply the water volume of the first heating pipe 120 and the water volumes of the second and third heating pipes 120, while the water volume flowing through the second connecting pipe needs to supply the water volumes of the second and third heating pipes 120, and the water flow through the third connecting pipe only needs to supply the water volume of the third heating pipe 120. That is to say, the opening area of the water inlet pipe 110 at the first first connecting pipe 140 is larger than that at the second first connecting pipe 140, and the opening area at the second first connecting pipe 140 is larger than that at the third first connecting pipe 140.

[0058] This way can ensure that under different water flows or pressures, multiple heating pipes 120 can have approximately the same water volume, and can make the heat exchange performance and the outlet water temperature of the entire heating assembly 100 more balanced.

[0059] In some embodiments, the first connecting pipe 140 is perpendicular to the water inlet pipe 110, that is, multiple first connecting pipes 140 are all perpendicular to the water inlet pipe 110, such that the included angles between all the first connecting pipes 140 and the water inlet pipe 110 are the same, so that the resistance of the water flowing from the water inlet pipe 110 into different first connecting pipes 140 is substantially the same, enabling the water to flow quickly into different heating pipes 120, and as much as possible avoiding the situation where the water flow rate in different second water outlets 114 is uneven, resulting in different water flow rates in the heating pipes 120, and the occurrence of dry burning due to a relatively small water flow in a certain heating pipe 120.

[0060] In some embodiments, multiple second water outlets 114 are located at the same height. This means that the heights of multiple second water outlets 114 are the same. After the water in the water inlet pipe 110 flows from the second water inlet 112 to the second water outlets 114, it enters different first connecting pipes 140 through different second water outlets 114. The same height of multiple second water outlets 114 makes the resistance of the water flowing into different first connecting pipes 140 substantially the same, enabling the water to flow quickly into different heating pipes 120, and as much as possible avoiding the situation where the water flow rate in different second water outlets 114 is uneven, resulting in different water flow rates in the heating pipes 120, and the occurrence of dry burning due to a relatively small water flow in a certain heating pipe 120.

[0061] In some embodiments, multiple first water inlets 121c are located at the same height.

[0062] Among them, multiple first water inlets 121c being located at the same height means that the first water inlets 121c of multiple heating pipes 120 are located at the same height. When the heating component 100 is installed and in use, the axial direction of the heating pipe 120 is approximately the vertical direction. In the axial direction of the heating pipe 120, that is, in the vertical direction, the first water inlets 121c of multiple heating pipes 120 are located at the same height.

[0063] The first water inlets 121c of multiple heating pipes 120 are located at the same height. When water flows from different first connecting pipes 140 into different heating pipes 120, since the multiple first water inlets 121c are located at the same height, the resistance of different combinations of first connecting pipes 140 and heating pipes 120 is substantially the same, enabling the water flow to quickly enter different heating pipes 120 and be quickly distributed in each heating pipe 120, avoiding the situation where there is no water in the heating pipe 120 and dry burning occurs in the heating pipe 120 that is relatively far from the second water inlet 112 during the initial startup of the heating component 100.

[0064] Meanwhile, since multiple first water inlets 121c are at the same height, that is, multiple first water inlets 121c are on the same horizontal line, in different combinations of the first connecting pipes 140 and the heating pipes 120, the resistance of the water flowing into the heating pipes 120 is substantially the same, enabling the water flow to always maintain a stable flow rate and flow into each heating pipe 120, thereby improving the working stability of the entire heating assembly 100.

[0065] Please refer to Figure 3 and Figure 4 In some embodiments, the first water outlets 121b of multiple heating pipes 120 are connected and communicated in sequence, and the first water outlet 121b of one of the heating pipes 120 is directly communicated with the water outlet pipe 130.

[0066] The first water outlets 121b of multiple heating pipes 120 are connected in sequence, that is, the water inlet pipes 110 of multiple heating pipes 120 are communicated with each other. When the water in different heating pipes 120 flows to their respective first water outlets 121b, it can flow between the first water outlets 121b of multiple heating pipes 120. If one of the heating pipes 120 is blocked or damaged and cannot work properly, the water can flow into the first water outlet 121b of the adjacent heating pipe 120, and after being heated by this heating pipe 120, it is discharged through the water outlet pipe 130. This can alleviate the problem of excessive water pressure in the branch due to the blockage of one of the heating pipes 120 and avoid the problem of pipe explosion caused by blockage.

[0067] That is to say, in the embodiments of the present application, multiple heating pipes 120 are connected in parallel, but the first water outlets 121b of multiple heating pipes 120 are connected in series. Through this connection method, the first water outlets 121b of multiple heating pipes 120 are communicated, which can reduce the problem of pipe explosion caused by the increase in water pressure in one of the heating pipes 120 due to blockage. At the same time, multiple heating pipes 120 are connected in parallel, and multiple heating pipes 120 can heat different water simultaneously, increasing the water output of the water outlet pipe 130 within the same time, and increasing the water output from the third water outlet 131b in a short time, enabling users to use enough hot water in a short time and improving the comfort of users.

[0068] In some embodiments, the first water outlet 121b can be two, and the two first water outlets 121d are located at the same end of the heating pipe 120. The heating assembly 100 further includes multiple second connecting pipes 150, and the first water outlets 121d of adjacent two heating pipes 120 are communicated through the second connecting pipes 150. The third water inlet 131a is connected to any one of the second connecting pipes 150 or to one of the first water outlets 121d.

[0069] Among them, multiple heating tubes 120 are arranged in sequence. The first water outlet 121b of the heating tube 120 in the middle can be set to two. Among the two heating tubes 120 at both ends, the first water outlet 121b of the heating tube 120 connected to the water outlet pipe 130 can be set to two, and the first water outlet 121b of the other heating tube 120 can be set to only one. The two first water outlets 121d are respectively connected to two adjacent heating tubes 120. Specifically, the first water outlets 121d of two adjacent heating tubes 120 can be directly connected or connected through a second connecting pipe 150. The second connecting pipe 150 can connect two adjacent heating tubes 120, so that there is a certain gap between two adjacent heating tubes 120, avoiding mutual influence between two adjacent heating tubes 120 during operation. At the same time, having a certain gap between two adjacent heating tubes 120 facilitates the heat dissipation of each heating tube 120 and improves the service life of the heating tube 120.

[0070] In some embodiments, multiple second connecting pipes 150 are connected in series through the heating tubes 120. That is, multiple second connecting pipes 150 and the first water outlets 121b of multiple heating tubes 120 are alternately connected, and multiple second connecting pipes 150 and the first water outlets 121b of multiple heating tubes 120 are alternately connected in series, so that the first water outlets 121b of multiple heating tubes 120 are connected in series. After water enters the first water outlet 121b of one of the heating tubes 120, it can flow between multiple heating tubes 120. The second connecting pipe 150 plays the role of connecting the first water outlets 121b of the heating tubes 120 and can also arrange two adjacent heating tubes 120 at intervals.

[0071] Among them, the third water inlet 131a can communicate with any one of the second connecting pipes 150 or with the first water outlet 121d that is not connected to the second connecting pipe 150, as long as it can be ensured that it communicates with multiple first water outlets 121b.

[0072] In some embodiments, in the direction close to the third water inlet 131a, the opening areas of multiple first water outlets 121d increase in sequence.

[0073] Similarly, within the same heating tube 120, the water flow direction is also towards the direction near the third water inlet 131a. The first water outlet 121d near the third water inlet 131a can be understood as the outlet, and the first water outlet 121d far from the third water inlet 131a can be understood as the inlet. The first water outlets 121b of multiple heating tubes 120 are connected in series. The closer the heating tube 120 is to the third water inlet 131a, the greater the water flow rate collected at the first water outlet 121b of the heating tube 120, and the opening area of the first water outlet 121d needs to be increased so that the hot water heated by the heating tube 120 can be discharged to the water outlet pipe 130 in a timely manner, enabling each heating tube 120 to be reasonably utilized and improving the heating energy efficiency of the entire heating assembly 100.

[0074] In some embodiments, the first water inlet 121a of each heating tube 120 is connected to the water inlet pipe 110, and the first water outlet 121b of each heating tube 120 is connected to the water outlet pipe 130.

[0075] The first water inlet 121a of each heating tube 120 being connected to the water inlet pipe 110 and the first water outlet 121b of each heating tube 120 being connected to the water outlet pipe 130 indicates that multiple heating tubes 120 are connected in parallel, that is, the heating of multiple heating tubes 120 is independent of each other. The water in the water inlet pipe 110 becomes hot water after being heated by one of the heating tubes 120 and enters the water outlet pipe 130. That is to say, multiple heating tubes 120 can heat different water simultaneously, increasing the amount of hot water in the water outlet pipe 130 at the same time and increasing the water output from the third water outlet 131b in a short time, enabling the user to use enough hot water in a short time and improving the user's comfort.

[0076] At the same time, multiple heating tubes 120 are connected in parallel with each other. Each heating tube 120 only needs to bear the heating of a part of the water, and the working load of the heating tube 120 is low, thereby reducing the failure rate of the heating tube 120 and increasing the service life of the heating tube 120.

[0077] Please refer to Figure 5 and Figure 6 , in some embodiments, the water outlet pipe 130 includes a transition portion 132, a bending portion 134, and a water outlet portion 136 connected in sequence. One end of the transition portion 132 far from the bending portion 134 is connected to the first water outlet 121b. The plane where the bending portion 134 is located is perpendicular to the plane where the first direction and the second direction are located together. The second direction is the length direction of the heating tube 120.

[0078] The second direction and the third direction form a coordinate system. Specifically, the first direction, the second direction, and the third direction can be perpendicular to each other pairwise. The third direction is the thickness direction of the heating tube 120 (as shown in Figure 1 , where X represents the first direction, Y represents the second direction, and Z represents the third direction).

[0079] The plane where the bending portion 134 is located is perpendicular to the plane where the first direction and the second direction are located. The first direction is the width direction of the entire heating component 100, and the second direction is the length direction of the entire heating component 100. The plane where the bending portion 134 is located is perpendicular to the plane where the first direction and the second direction are located, which means that the bending portion 134 is not arranged in the first direction and the second direction. The plane where the bending portion 134 is located can be a plane where the second direction and the third direction are located, or it can be a plane where the first direction and the third direction are located. Regardless of whether the plane where the bending portion 134 is located is a plane where the second direction and the third direction are located or a plane where the first direction and the third direction are located, at least part of the bending portion 134 is arranged in the third direction, that is, the bending portion 134 is arranged along the thickness direction of the heating tube 120, so that the bending portion 134 can not occupy the size of the entire heating component 100 in the width direction, thereby reducing the width of the entire heating component 100, making the heating component 100 more miniaturized.

[0080] It should be noted that the third direction is perpendicular to the first direction and the second direction, which is not absolutely 90 degrees, but means that the angle between the third direction and the first direction is between 80 degrees and 100 degrees, and the angle between the third direction and the second direction is between 80 degrees and 100 degrees. Similarly, the perpendicularity mentioned in this application refers to the angle between the two being between 80 degrees and 100 degrees.

[0081] In some embodiments, at least part of the bend 134 is located above the heating tube 120. This means that at least part of the bend 134 is higher than the heating tube. At least part of the bend 134 is higher than the heating tube 120, and the entire bend 134 may be higher than the heating tube 120, or part of the bend 134 may be higher than the heating tube 120, and part of the bend 134 may be lower than the heating tube 120. Regardless of the above situation, during the operation of the heating component 100, hot water needs to pass through the bend 134 above the heating tube 120 before it is discharged outside the heating component 100. Since the bend 134 is connected to the heating tube 120, when the hot water passes through the part of the bend 134 located above the heating tube 120, it means that there is heat in all of the heating tube 120, that is, the hot water fills the entire heating tube 120, and there is basically no situation where part of the heating tube 120 is dry. The dry burning of the heating tube 120 can be avoided as much as possible, the failure rate of the heating tube 120 is reduced, and the service life of the heating tube 120 is increased.

[0082] In the working state, the entire heating tube 120 is arranged in the vertical direction, that is, the second direction is the vertical direction, and the first water outlet 121b is located at the top of the heating tube 120, and the first water inlet 121a is located at the bottom of the heating tube 120. At least part of the bending portion 134 is higher than the first water outlet 121b.

[0083] When water flows into the heating tube 120 and then flows from the bottom of the heating tube 120 to the top of the heating tube 120, the water can flow through the entire heating tube 120, enabling the heat exchange time with the heating tube 120, effectively taking away the heat on the surface of the heating tube 120, reducing the heat density during the operation of the heating tube 120, and prolonging the service life of the heating tube 120 and reducing the failure rate of the heating tube 120.

[0084] Since the first water outlet 121b is located at the top of the heating tube 120, that is to say, the first water outlet 121b is located at the uppermost part of the entire heating tube 120, at least part of the water outlet pipe 130 is arranged higher than the first water outlet 121b. When the hot water in the heating tube 120 flows out from the first water outlet 121b through the upper water outlet pipe 130, the entire heating tube 120 is filled with water, and basically there will be no situation where part of the height in the heating tube 120 will have dry burning, thereby reducing the failure rate of the heating tube 120 and increasing the service life of the entire heating assembly 100.

[0085] In some embodiments, the bending portion 134 includes a first connecting section 134a, a second connecting section 134b, and a third connecting section 134c connected in sequence. One end of the first connecting section 134a away from the second connecting section 134b is communicated with the transition portion 132, and one end of the third connecting section 134c away from the second connecting section 134b is communicated with the water outlet portion 136; the first connecting section 134a and the third connecting section 134c extend along the first direction, and the second connecting section 134b extends along the third direction.

[0086] The second connecting section 134b mainly serves to connect the first connecting section 134a and the third connecting section 134c. The second connecting section 134b extends along the third direction, so that the first connecting section 134a and the third connecting section 134c are spaced apart in the third direction, that is, the first connecting section 134a and the third connecting section 134c are arranged in the third direction. In other words, the first connecting section 134a and the third connecting section 134c are arranged in the thickness direction of the entire heating assembly 100. Compared with the situation where the first connecting section 134a, the second connecting section 134b, and the third connecting section 134c are arranged along the width direction of the heating assembly 100, the occupied space in the width direction of the entire water outlet pipe 130 can be reduced, thereby minimizing the width of the entire heating assembly 100 as much as possible and making the entire heating assembly 100 miniaturized.

[0087] The second connecting section 134b is located above the heating pipe 120, and both the first connecting section 134a and the third connecting section 134c are located below the second connecting section 134b.

[0088] The second connecting section 134b is the highest point of the entire water outlet pipe 130. The water flowing out from the first water outlet 121b enters the first connecting section 134a through the transition part 132 and flows upward. After flowing into the second connecting section 134b, it then enters the third connecting section 134c and finally flows out of the water outlet pipe 130 through the water outlet part 136.

[0089] That is to say, in the entire connecting pipe, the second connecting section 134b is the highest point of the entire water outlet pipe 130. The hot water flowing out from the water outlet section 136b first rises through the first connecting section 134a, then enters the inflection point in the second connecting section 134b, flows downward, enters the third connecting section 134c, and finally is discharged from the water outlet part 136 to the outside of the entire heating assembly 100.

[0090] During the process of the hot water rising through the first connecting section 134a, if there is gas in the hot water, the gas will enter the second connecting section 134b along the upward path through the first connecting section 134a, which can reduce the accumulation of gas at the first water outlet 121b and minimize the situation where the pressure in the heating pipe 120 is too high, resulting in damage to the heating pipe 120.

[0091] In some embodiments, the projections of the first connecting section 134a and the third connecting section 134c on the plane where the first direction and the second direction are located overlap. This arrangement can reduce the occupied space of the water outlet pipe 130 in the width direction of the entire heating assembly 100, thereby reducing the width of the entire heating assembly 100.

[0092] Among them, the projections of the first connecting section 134a and the third connecting section 134c on the plane where the first direction and the second direction are located overlap, which can be that the projections of the first connecting section 134a and the third connecting section 134c on the plane where the first direction and the second direction are located completely overlap, or that only part of the projections of the first connecting section 134a and the third connecting section 134c on the plane where the first direction and the second direction are located overlap.

[0093] The first direction is the width direction of the heating assembly 100, and the second direction is the length direction of the heating assembly 100. The projections of the first connecting section 134a and the third connecting section 134c on the plane where the first direction and the second direction are located overlap, so that the first connecting section 134a and the third connecting section 134c overlap and are spaced apart in the third direction.

[0094] The first connecting section 134a and the third connecting section 134c are sequentially arranged in the thickness direction of the entire heating component 100. Among them, the heating tube 120 is substantially cylindrical, the diameter of the heating tube 120 is larger than the diameter of the water outlet pipe 130, and the first connecting section 134a and the third connecting section 134c are sequentially arranged in the thickness direction of the heating tube 120, so that the overall thickness of the first connecting section 134a and the third connecting section 134c is not much different from the thickness of the heating tube 120. While reducing the width of the entire heating component 100, the thickness of the heating component 100 is hardly increased.

[0095] In some embodiments, the water outlet part 136 includes a transition section 136a and a water outlet section 136b. The third connecting section 134c is communicated with the water outlet section 136b through the transition section 136a. The transition section 136a is inclined, and the water outlet section 136b is located below the first connecting section 134a.

[0096] In the use state, the first connecting section 134a is arranged behind the third connecting section 134c, the water outlet section 136b is arranged below the first connecting section 134a, and the transition section 136a is inclined, so that the water outlet section 136b can be arranged below the first connecting section 134a, facilitating the installation and fixation of the water outlet section 136b.

[0097] In some embodiments, the water outlet section 136b is arranged side by side with the heating tube 120. That is, the water outlet section 136b and the plurality of heating tubes 120 are arranged side by side, indicating that the water outlet section 136b is arranged in the width direction of the heating tube 120, which can facilitate the installation and fixation of the water outlet section 136b.

[0098] A first inflection point is formed at the connection between the transition section 136a and the bending part 134, and a second inflection point is formed at the connection between the transition section 136a and the water outlet section 136b.

[0099] Specifically, the transition section 136a is connected to the third connection section 134c. Since the second connection section 134b of the bending portion 134 extends in the third direction, the third connection section 134c may protrude outside the heating tube 120. The connection section between the transition section 136a and the third connection section 134c forms a first inflection point, which can make the transition section 136a inclined inwardly, thus facilitating the arrangement of the entire water outlet section 136. In addition, the connection between the transition section 136a and the third connection section 134c forms an inflection point, indicating that the extending direction of the transition section 136a is different from that of the third connection section 134c. When the water flow flows from the third connection section 134c into the transition section 136a, the water flow direction can change, causing the water flow to collide between the pipe wall of the third connection section 134c and the pipe wall of the transition section 136a, which can play a certain buffering role in the water flow velocity, slow down the flow velocity, and enable the water flow to mix more fully, improving the uniformity of the water outlet temperature of the entire heating assembly 100.

[0100] Similarly, the connection between the transition section 136a and the water outlet section 136b forms a second inflection point, indicating that the extending direction of the transition section 136a is different from that of the water outlet section 136b. When the water flow flows from the transition section 136a into the water outlet section 136b, the water flow direction can change, causing the water flow to collide between the pipe wall of the water outlet section 136b and the pipe wall of the transition section 136a, which can play a certain buffering role in the water flow velocity, slow down the flow velocity, and enable the water flow to mix more fully, improving the uniformity of the water outlet temperature of the entire heating assembly 100.

[0101] In some embodiments, the projection of the water outlet section 136b in the plane where the second direction and the third direction are located together coincides with the projection of the heating tube 120 in the plane where the second direction and the third direction are located together.

[0102] Wherein, the second direction is the length direction of the heating tube 120, and the third direction is the thickness direction of the heating tube 120. Then the plane where the second direction and the third direction are located together is the plane where the thickness of the heating tube 120 is located. The projection of the water outlet section 136b in the plane where the second direction and the third direction are located together coincides with the projection of the heating tube 120 in the projection plane, indicating that the water outlet section 136b is located within the thickness range of the heating tube 120 and does not protrude outside the thickness direction of the heating tube 120. Since the water outlet section 136b is the hot water outlet of the entire heating assembly 100 and needs to be connected to the external use end, the water outlet section 136b being located within the thickness range of the heating tube 120 can facilitate the connection between the water outlet section 136b and the external use end, thus facilitating the installation of the entire heating assembly 100.

[0103] In some embodiments, the cross-sections of the water outlet pipe 130 and the heating pipe 120 are both circular, and the diameter of the water outlet pipe 130 is smaller than the radius of the heating pipe 120.

[0104] Among them, the heating pipe 120 is the heating main body 124b of the entire heating assembly 100, mainly used for heating water. The water outlet pipe 130 is mainly used for allowing the water heated by the heating pipe 120 to flow out of the heating assembly 100. The fact that the diameter of the water outlet pipe 130 is smaller than the radius of the heating pipe 120 can be considered that the diameter of the water outlet pipe 130 is relatively small, while the diameter of the heating pipe 120 is relatively large. During the heating process, due to the relatively small diameter of the water outlet pipe 130, the water flow rate in the water outlet pipe 130 is small. When the external cold water enters the heating pipe 120 from the water inlet pipe 110, it can make the water flow stay in the heating pipe 120 for a longer time, increasing the heat exchange time with the heating pipe 120, enabling the water to fully exchange heat with the heating pipe 120, and thus ensuring the water temperature flowing out of the water outlet pipe 130 and improving the user experience.

[0105] Specifically, the diameters of all parts of the water outlet pipe 130 are the same, that is, the diameters of the transition part 132, the bending part 134, and the water outlet part 136 are all smaller than the radius of the heating pipe 120. That is to say, the diameters of the first connecting section 134a, the second connecting section 134b, and the third connecting section 134c are all smaller than the radius of the heating pipe 120.

[0106] In addition, since the first connecting section 134a and the third connecting section 134c are overlapped in the thickness direction of the heating pipe 120, that is, in the thickness direction of the heating pipe 120, the diameter of the first connecting section 134a, the diameter of the third connecting section 134c, and the distance between the first connecting section 134a and the third connecting section 134c are the thickness of the entire bending part 134. Since the diameters of the first connecting section 134a and the third connecting section 134c are both smaller than the radius of the heating pipe 120, that is, the sum of the diameters of the first connecting section 134a and the third connecting section 134c is smaller than the diameter of the heating pipe 120, and the distance between the first connecting section 134a and the third connecting section 134c is not too large, making the thickness of the entire bending part 134 approximately equal to the thickness of the heating pipe 120 or the thickness of the bending part 134 is slightly larger than the thickness of the heating pipe 120. This way can minimize the part where the bending part 134 protrudes from the heating pipe 120 and can also minimize the increase in the thickness of the entire heating assembly 100.

[0107] In some embodiments, the transition part 132 is directly communicated with the first water outlet 121b of one of the heating pipes 120, and the transition part 132 extends along the first direction.

[0108] The transition part 132 is the water inlet end of the entire water outlet pipe 130. The water flowing out from the first water outlet 121b of the heating pipe 120 directly enters the transition part 132, and the transition part 132 extends along the first direction. That is, the transition part 132 extends along the width direction of the heating assembly 100. Since the length of the transition part 132 is very short, it basically does not increase the size of the entire heating assembly 100 in the width direction.

[0109] Please refer to Figure 7 and Figure 8 , in some embodiments, the heating pipe 120 includes: a housing 122, a heating element 123, an upper cover 124, and a seal 125. The housing 122 has a receiving cavity 122a and an opening 122b communicating with the receiving cavity 122a. The housing 122 has a first connecting portion 126 inside; the heating element 123 is installed in the receiving cavity 122a; the upper cover 124 is provided with a second connecting portion 127, and the second connecting portion 127 cooperates with the first connecting portion 126; the seal 125 is sleeved on the upper cover 124, is spaced from the second connecting portion 127, and abuts against the inner wall of the housing 122.

[0110] Among them, the housing 122 is the main body 124b of the entire heating pipe 120, providing a mounting basis for components such as the heating element 123 and the seal 125, and capable of accommodating and protecting structures such as the heating element 123. The heating element 123 is arranged inside the housing 122 and is used to heat the water entering the housing 122. After being heated to the set temperature, it is discharged outside the housing 122.

[0111] The receiving cavity 122a is mainly used to hold water. Therefore, the receiving cavity 122a needs to be a sealed cavity. The upper cover 124 covers the opening 122b, and the gap between the upper cover 124 and the housing 122 needs to be sealed. The seal 125 is installed on the upper cover 124 and is used to seal the gap between the upper cover 124 and the housing 122. The first connecting portion 126 cooperates with the second connecting portion 127, so that the upper cover 124 can be installed on the opening 122b of the housing 122. Since the first connecting portion 126 needs to cooperate with the second connecting portion 127, mutual acting forces will be received during the cooperation process. If the seal 125 contacts the second connecting portion 127, during the cooperation process of the second connecting portion 127, the seal 125 may be deformed due to the acting force of the first connecting portion 126, resulting in a gap between the upper cover 124 and the housing 122, thus causing water leakage.

[0112] In the embodiment of the present application, the seal 125 and the second connection part 127 are spaced apart so that there is a certain distance between the seal 125 and the second connection part 127. During the cooperation between the first connection part 126 and the second connection part 127, since there is a certain distance between the second connection part 127 and the seal 125, the force of the first connection part 126 is basically not used for the seal 125, thereby reducing the deformation of the seal 125 due to other forces, thereby avoiding the gap between the upper cover 124 and the shell 122 as much as possible, and improving the sealing performance between the upper cover 124 and the shell 122.

[0113] In some embodiments, the heating element 123 is fixedly connected to the upper cover 124. When assembling the heat pipe 120, it is only necessary to assemble the heating element 123 and the upper cover 124 as a whole onto the housing 122. The assembly method is simple, and when the heating element 123 needs to be inspected, the upper cover 124 and the housing 122 are first separated, and then the entire upper cover 124 and the heating element 123 are taken out from the housing 122.

[0114] See also Figure 9 and Figure 10 In some embodiments, the upper cover 124 is provided with a mounting groove 124 a , the mounting groove 124 a is spaced apart from the second connecting portion 127 , and the sealing member 125 is installed in the mounting groove 124 a .

[0115] The mounting groove 124a is arranged in a ring around the outer circumference of the upper cover 124. It can be considered that the sealing member 125 is sleeved on the upper cover 124 and abuts against the inner wall of the shell 122 to seal the gap between the upper cover 124 and the shell 122, so that the accommodating cavity 122a is a sealed cavity. The sealing member 125 is installed in the sealing groove. The sealing groove can seal and play a fixing role, which can reduce the risk of the sealing member 125 falling off the upper cover 124.

[0116] At the same time, the installation groove 124a and the second connecting part 127 are spaced apart so that there is a certain distance between the installation groove 124a and the second connecting part 127. The groove wall of the installation groove 124a can also play a certain blocking role on the seal 125, and can separate the seal 125 from the first connecting part 126, thereby reducing the risk of the force of the first connecting part 126 being applied to the seal 125 during the mating process between the first connecting part 126 and the second connecting part 127.

[0117] In some embodiments, the width of the mounting groove 124a is 2 mm to 5 mm, the mounting groove 124a is annular, and the diameter of the bottom of the mounting groove 124a is 20 mm to 50 mm.

[0118] The width of the installation groove 124a refers to the width in the direction close to the accommodating cavity 122a, and is also the width in the extending direction of the heating tube 120. The installation groove 124a is arranged in a ring on the outer peripheral surface of the upper cover 124, and the bottom of the installation groove 124a is also annular. Similarly, the sealing member 125 is also annular and is clamped in the installation groove 124a. The sealing member is annular and has an outer diameter of 20 mm to 50 mm. This indicates that the size of the entire upper cover 124a is very small, and it is necessary to make the installation groove 124a fit the sealing member 125 to avoid water leakage.

[0119] In some embodiments, the upper cover 124 includes a main body 124b, a cover plate 124c and a partition plate 124d, the cover plate 124c is arranged at one end of the main body 124b, the partition plate 124d is arranged on the main body 124b and forms a mounting groove 124a with the cover plate 124c, and the second connecting portion 127 is arranged around the main body 124b and is located on the side of the partition plate 124d away from the cover plate 124c.

[0120] The cover plate 124c covers the opening 122b, the partition plate 124d is installed in the accommodating cavity 122a, and the sealing member 125 is located in the installation groove 124a formed by the cover plate 124c and the partition plate 124d, that is, the sealing member 125 and the second connecting portion 127 are respectively located on both sides of the partition plate 124d, and the partition plate 124d separates the sealing member 125 from the second connecting portion 127. In the process of the first connecting portion 126 and the second connecting portion 127 being matched, the partition plate 124d can isolate the sealing member 125 from the second connecting portion 127, and can reduce the force of the first connecting portion 126 acting on the sealing member 125, so that the sealing member 125 is deformed by the force, resulting in a gap between the upper cover 124 and the shell 122. The partition 124d separates the sealing member 125 from the second connecting portion 127 , which can minimize the risk of deformation of the sealing member 125 due to other external forces, thereby improving the sealing effect of the sealing member 125 on the shell 122 and the upper cover 124 .

[0121] Among them, the second connection part 127 can extend to the partition 124d. For example, when the first connection part 126 and the second connection part 127 are threaded, the second connection part 127 can extend to the partition 124d, and the thread can extend along to the partition 124d. Even if the first connection part 126 and the second connection part 127 are threadedly engaged to the partition 124d, due to the obstruction of the partition 124d, the second connection part 127 will not move into the accommodating chamber 122a, that is, the first connection part 126 will not move to the seal 125 and will not squeeze the seal 125, thereby avoiding the seal 125 from being deformed by other forces as much as possible.

[0122] In some embodiments, the partition 124d is disposed around the main body 124b in a ring shape. The cover plate 124c is disposed at one end of the main body 124b. The installation groove 124a formed by the partition 124d, the main body 124b, and the cover plate 124c is also a ring structure. The installation groove 124a is disposed around the outer periphery of the main body 124b, such that the seal 125 is also disposed around the outer periphery of the main body 124b, can contact the inner wall of the housing 122, and abut against the inner wall of the housing 122, thereby sealing the gap between the main body 124b and the inner wall of the housing 122.

[0123] Among them, the cross-sections of the cover plate 124c, the main body 124b, and the partition 124d are all circular. The diameter of the main body 124b is the smallest, the diameter of the cover plate 124c is the largest, and the diameter of the partition 124d is greater than the diameter of the main body 124b and less than the diameter of the cover plate 124c. The diameter of the cover plate 124c can be slightly larger than the size of the opening 122b of the accommodation cavity 122a, so as to be able to completely cover the opening 122b.

[0124] In some embodiments, the projection of the second connection portion 127 on the partition 124d is located within the partition 124d. The second connection portion 127 is disposed around the outer periphery of the partition 124d, and the partition 124d is also disposed around the outer periphery of the main body 124b. If the projection of the second connection portion 127 on the partition 124d is located within the partition 124d, it indicates that the height by which the second connection portion 127 protrudes from the main body 124b is less than the height by which the partition 124d protrudes from the main body 124b. During the cooperation process of the first connection portion 126 and the second connection portion 127, the first connection portion 126 will extend below the partition 124d to cooperate with the second connection portion 127. The partition 124d can isolate the first connection portion 126 and the second connection portion 127. During the cooperation process of the first connection portion 126 and the second connection portion 127, the first connection portion 126 hardly contacts the seal 125, and basically no other force except the housing 122 acts on the seal 125, thereby being able to improve the sealing effect of the seal 125.

[0125] In some embodiments, the installation groove 124a is disposed around the upper cover 124, and at least a part of the seal 125 protrudes outside the installation groove 124a. The seal 125 is a ring structure and is installed in the installation groove 124a, that is, disposed around the installation groove 124a in a ring shape. The part of the seal 125 protruding outside the installation groove 124a can facilitate the abutment of the seal 125 against the inner wall of the housing 122. The part of the seal 125 protruding outside the installation abuts against the inner wall of the housing 122, can seal the gap between the upper cover 124 and the housing 122, reduces the risk of water leakage in the entire heating tube 120, and improves the sealing performance of the entire heating tube 120.

[0126] In some embodiments, in the second connecting portion 127 and the mounting groove 124a, the second connecting portion 127 is disposed close to the accommodating cavity 122a, and the mounting groove 124a is disposed away from the accommodating cavity 122a. In the use state, the second connecting portion 127 is disposed below the mounting groove 124a, that is, the second connecting portion 127 is disposed below the seal 125, the heating member 123 is installed in the accommodating cavity 122a, and the seal 125 can seal the upper portion of the entire accommodating cavity 122a.

[0127] In some embodiments, the accommodating cavity 122a has a first mounting section 122c and a second mounting section 122d that communicate with each other. The opening area of the second mounting section 122d is larger than the opening area of the first mounting section 122c. The heating member 123 is disposed in the second mounting section 122d, and the seal 125 is disposed in the first mounting section 122c.

[0128] The first mounting section 122c and the second mounting section 122d are in a stepped shape. The opening area of the second mounting section 122d is larger, and the opening area of the first mounting section 122c is smaller. The seal 125 and the upper cover 124 are disposed in the first mounting section 122c, which can facilitate the upper cover 124 and the seal 125 to seal the opening 122b of the entire accommodating cavity 122a.

[0129] In some embodiments, the first connecting portion 126 is disposed around the accommodating cavity 122a, and the second connecting portion 127 is disposed around the outer periphery of the upper cover 124. Both the first connecting portion 126 and the second connecting portion 127 are threads. The first connecting portion 126 is an internal thread disposed around the accommodating cavity 122a, and the second connecting portion 127 is an external thread disposed around the outer periphery of the upper cover 124. The internal thread can be formed together with the housing 122.

[0130] In some embodiments, the housing 122 includes a heating chamber 122e and a sealing joint 122f. The sealing joint 122f is connected to one end of the heating chamber 122e. The heating chamber 122e and the sealing joint 122f together form the accommodating cavity 122a. The first mounting section 122c is disposed in the sealing joint 122f, the second mounting section 122d is disposed in the heating chamber 122e, and the first connecting portion 126 is also disposed in the sealing joint 122f.

[0131] Wherein, the first mounting section 122c includes a first sub-section 122g and a second sub-section 122h that communicate with each other. The first sub-section 122g is disposed close to the second mounting section 122d, and the second sub-section 122h is disposed away from the first mounting section 122c. The opening area of the first sub-section 122g is smaller than the opening area of the second sub-section 122h. The cover body is installed in the second sub-section 122h, the first connecting portion 126 is disposed on the inner wall of the first sub-section 122g, and the second connecting portion 127 is installed in the first sub-section 122g and assembled with the first connecting portion 126.

[0132] In some embodiments, the diameter of the second sub-segment 122h is 20 mm to 50 mm, and the thickness of the second sub-segment 122h is 4 mm to 8 mm. The thickness of the housing 122 corresponding to the second sub-segment 122h is 1 mm to 4 mm. The second sub-segment 122h is mainly used to accommodate the cover plate 124c. Since the second sub-segment 122h is not connected to the first connecting portion 126, it will not receive the acting force of the first connecting portion 126. Therefore, the width of the first sub-segment 122h does not need to be set too thick, 4 mm to 8 mm is sufficient. Similarly, the corresponding housing 122 does not need to be set too thick, 1 mm to 4 mm is sufficient. As for the diameter, it just needs to be adapted to the seal 125.
