[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] See also Figure 1 and Figure 2 The embodiment of the present application provides a heating component 100, which can be applied to electrical appliances that need heating, such as water heaters, water dispensers, smart toilets, and bathrooms. The heating component 100 provided in the embodiment of the present application can reduce the size of the heating component 100 and reduce the space occupied by the heating component 100.

[0048] In the embodiments of the present application, for the convenience of description, the heating component 100 heating water is used as an example for explanation. When the heating component 100 heats other liquids or heats gas, the same can be applied. 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 of 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.

[0049] In the embodiment of the present application, the heating component 100 includes: a plurality of heating tubes 120, a water inlet pipe 110 and a water outlet pipe 130, the plurality of heating tubes 120 are arranged along a first direction, the heating tube 120 has a first water inlet 121a and a first water outlet 121b; the water outlet pipe 130 is connected to the first water outlet 121b, and the water inlet pipe 110 is connected to the first water outlet 121b;

[0050] Among them, the water outlet pipe 130 includes a transition portion 132, a bending portion 134 and a water outlet portion 136 connected in sequence, and the end of the transition portion 132 away from the bending portion 134 is connected to the first water outlet 121b, and the plane where the bending portion 134 is located is perpendicular to the plane where the first direction and the second direction are located, and the second direction is the length direction of the heating tube 120.

[0051] In the embodiment of the present application, the heating pipe 120 is the main device for heating the entire heating component 100. After the cold water in the water inlet pipe 110 enters the heating pipe 120, it is heated by the heating pipe 120 and then flows out from the water outlet pipe 130. After entering the heating pipe 120, the cold water flows along the extension direction of the heating pipe 120, and finally flows out from the water outlet pipe 130 after being heated at different positions of the heating pipe 120.

[0052] The water inlet pipe 110 is a strip-shaped through pipe, and the second water inlet 112 of the water inlet pipe 110 is connected to an external water source. The second water outlet 114 of the water inlet pipe 110 is connected to the first water inlet 121a, and is used to drain external cold water into the entire heating component 100, so that the heating component 100 can heat cold water into hot water. The third water inlet 131a of the water outlet pipe 130 is connected to the first water outlet 121b, and the third water outlet 131b of the water outlet pipe 130 will be used to connect to an external use end, and is used to output the hot water heated by the heating component 100 to the outside of the heating component 100 for user use.

[0053] The heating tube 120 is roughly in the shape of a long strip, and the first water inlet 121a and the first water outlet 121b are two different ends of the heating tube 120. The temperature of the hot water flowing out of the first water outlet 121b is related to 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 is, the higher the temperature of the hot water entering the water outlet pipe 130 is. On the contrary, the shorter the heating tube 120 is, the lower the temperature of the hot water entering the water outlet pipe 130 is. Similarly, when the length of the heating tube 120 is the same, the higher the power is, the higher the temperature of the hot water entering the water outlet pipe 130 is. On the contrary, the lower the power is, the lower the temperature of the hot water entering the water outlet pipe 130 is. The length and power of the heating tube 120 can be set according to the working requirements of the entire heating component 100 to meet the demand for hot water.

[0054] In the embodiment of the present application, the water outlet pipe 130 is connected to 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 of the water outlet pipe 130.

[0055] Among them, multiple heating tubes 120 are arranged along the first direction, and since a single heating tube 120 is roughly in the shape of a long strip, the second direction is the length direction of the heating tube 120. If the heating tube 120 is cylindrical, the second direction is the axial direction of the heating tube 120. Multiple heating tubes 120 are arranged in the first direction, which can be considered as multiple heating tubes 120 being arranged in sequence in the first direction, that is, multiple heating tubes 120 are arranged side by side in sequence in the first direction, and the first direction can be the radial direction of the heating tube 120. Multiple heating tubes 120 are arranged radially. Since multiple heating tubes 120 are arranged in sequence in the first direction, the more the number of heating tubes 120 is, the longer the length in the first direction is. For the convenience of description, it can be defined that the first direction is the width direction of the heating component 100, and the second direction is the length direction of the heating component 100.

[0056] For the convenience of description, a third direction perpendicular to the first direction and the second direction is defined. It can be considered that the first direction, 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. The third direction is the thickness direction of the heat pipe 120 (such as Figure 1 As shown in , X represents the first direction, Y represents the second direction, and Z represents the third direction).

[0057] 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.

[0058] It should be noted that the third direction is perpendicular to the first direction and the second direction, not absolutely 90 degrees, but refers to 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 vertical mentioned in this application refers to the angle between the two being between 80 degrees and 100 degrees. In some embodiments, at least part of the bending portion 134 is located above the heating tube 120. It means that at least part of the bending portion 134 is higher than the heating tube. At least part of the bending portion 134 is higher than the heating tube 120, which can be all of the bending portion 134 higher than the heating tube 120, or part of the bending portion 134 is higher than the heating tube 120, and part of the bending portion 134 is lower than the heating tube 120. In either case, during the operation of the heating component 100, the hot water needs to pass through the bending portion 134 above the heating tube 120 before it is discharged outside the heating component 100. Furthermore, since the bent portion 134 is connected to the heating tube 120, when the hot water passes through the portion of the bent portion 134 located above the heating tube 120, it means that the heating tube 120 is completely filled with heat, 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 situation of the heating tube 120 being dry 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.

[0059] In the working state, the entire heating tube 120 is arranged along 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, the first water inlet 121a is located at the bottom of the heating tube 120, and at least part of the bending portion 134 is higher than the first water outlet 121b.

[0060] When the water flows into the heating tube 120, it flows from the bottom of the heating tube 120 to the top of the heating tube 120, so that the water can flow through the entire heating tube 120, and can exchange heat with the heating tube 120 for a long time, 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.

[0061] Since the first water outlet 121b is located at the top of the heating tube 120, that is, the first water outlet 121b is located at the top of the entire heating tube 120, and at least a portion 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 the situation of dry burning at a certain height in the heating tube 120 is basically avoided, thereby reducing the failure rate of the heating tube 120 and increasing the service life of the entire heating assembly 100.

[0062] In some embodiments, the bending portion 134 includes a first connecting segment 134a, a second connecting segment 134b and a third connecting segment 134c connected in sequence, the end of the first connecting segment 134a away from the second connecting segment 134b is connected to the transition portion 132, and the end of the third connecting segment 134c away from the second connecting segment 134b is connected to the water outlet portion 136; the first connecting segment 134a and the third connecting segment 134c extend along the first direction, and the second connecting segment 134b extends along the third direction.

[0063] The second connecting segment 134b mainly serves to connect the first connecting segment 134a and the third connecting segment 134c. The second connecting segment 134b extends along the third direction, so that the first connecting segment 134a and the third connecting segment 134c are spaced apart in the third direction, that is, the first connecting segment 134a and the third connecting segment 134c are arranged in the third direction. In other words, the first connecting segment 134a and the third connecting segment 134c are arranged in the thickness direction of the entire heating component 100. Compared with the situation in which the first connecting segment 134a, the second connecting segment 134b and the third connecting segment 134c are arranged along the width direction of the heating component 100, the occupied space in the width direction of the entire water outlet pipe 130 can be reduced, thereby reducing the width of the heating component 100 as much as possible, so that the entire heating component 100 can be miniaturized.

[0064] The second connecting section 134 b is located above the heating tube 120 , and the first connecting section 134 a and the third connecting section 134 c are both located below the second connecting section 134 b .

[0065] 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 passes through the transition portion 132 and enters the first connecting section 134a and flows upward. After flowing into the second connecting section 134b, it enters the third connecting section 134c and finally flows out of the water outlet pipe 130 through the water outlet portion 136.

[0066] 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, and the hot water flowing out of the water outlet section 136b first rises through the first connecting section 134a, enters the inflection point in the second connecting section 134b, flows downward, enters the third connecting section 134c, and is finally discharged from the water outlet portion 136 to the outside of the entire heating component 100.

[0067] When the hot water rises through the first connecting section 134a, if there is gas in the hot water, the gas will enter the second connecting section 134b through the first connecting section 134a along the upward path, which can reduce the gas gathering at the first water outlet 121b and minimize the high gas pressure in the heating tube 120, which may cause damage to the heating tube 120.

[0068] 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 space occupied by the water outlet pipe 130 in the width direction of the entire heating component 100, thereby reducing the width of the entire heating component 100.

[0069] The projections of the first connecting segment 134a and the third connecting segment 134c on the plane where the first direction and the second direction are located overlap. The projections of the first connecting segment 134a and the third connecting segment 134c on the plane where the first direction and the second direction are located overlap completely, or the projections of the first connecting segment 134a and the third connecting segment 134c on the plane where the first direction and the second direction are located overlap only partially.

[0070] The first direction is the width direction of the heating component 100, and the second direction is the length direction of the heating component 100. The projections of the first connecting segment 134a and the third connecting segment 134c on the plane where the first direction and the second direction are located overlap, so that the first connecting segment 134a and the third connecting segment 134c are overlapped and arranged at intervals in the third direction. In other words, the first connecting segment 134a and the third connecting segment 134c are arranged in sequence in the thickness direction of the entire heating component 100. Among them, the heating pipe 120 is roughly cylindrical, and the diameter of the heating pipe 120 is greater than the diameter of the water outlet pipe 130. The first connecting segment 134a and the third connecting segment 134c are arranged in sequence in the thickness direction of the heating pipe 120, so that the overall thickness of the first connecting segment 134a and the third connecting segment 134c is not much different from the thickness of the heating pipe 120. While reducing the width of the entire heating component 100, the thickness of the heating component 100 is almost not increased.

[0071] In some embodiments, the water outlet portion 136 includes a transition section 136a and a water outlet section 136b, the third connecting section 134c is connected to 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.

[0072] When in use, 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 arranged at an angle so that the water outlet section 136b can be arranged below the first connecting section 134a, thereby facilitating the installation and fixation of the water outlet section 136b.

[0073] 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, which means 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.

[0074] A connection between the transition section 136a and the bent portion 134 forms a first inflection point, and a connection between the transition section 136a and the water outlet section 136b forms a second inflection point.

[0075] 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 out of the heating tube 120. The connection section between the transition section 136a and the third connection section 134c forms a first inflection point, which allows the transition section 136a to be tilted inward, thereby facilitating the arrangement of the entire water outlet portion 136. In addition, an inflection point is formed at the connection between the transition section 136a and the third connecting section 134c, which means that the extension direction of the transition section 136a is different from the extension direction of the third connecting section 134c. When the water flows from the third connecting section 134c into the transition section 136a, the direction of the water flow can change, so that the water flow can collide with the tube wall of the third connecting section 134c and the tube wall of the transition section 136a, which can have a certain buffering effect on the flow rate of the water flow and slow down the flow rate, so that the water flow can be more fully mixed, providing uniformity of the water outlet temperature of the entire heating component 100.

[0076] Similarly, a second inflection point is formed at the connection between the transition section 136a and the water outlet section 136b, which means that the extension direction of the transition section 136a is different from the extension direction of the water outlet section 136b. When the water flows from the transition section 136a into the water outlet section 136b, the direction of the water flow can change, so that the water flow can collide with the pipe wall of the water outlet section 136b and the pipe wall of the transition section 136a, which can have a certain buffering effect on the flow rate of the water flow and slow down the flow rate, so that the water flow can be more fully mixed, providing uniformity of the water outlet temperature of the entire heating component 100.

[0077] In some embodiments, the projection of the water outlet section 136b in the plane where the second direction and the third direction are located coincides with the projection of the heating pipe 120 in the plane where the second direction and the third direction are located.

[0078] 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, and the common plane of the second direction and the third direction is the plane where the thickness of the heating tube 120 is located. The projection of the water outlet section 136b in the common plane of the second direction and the third direction coincides with the projection of the heating tube 120 in the common plane of the second direction and the third direction, which means that the water outlet section 136b is located within the thickness range of the heating tube 120, and the water outlet section 136b is not protruding outside the thickness direction of the heating tube 120. Since the water outlet section 136b is the hot water outlet of the entire heating component 100 and needs to be connected to the external user end, the water outlet section 136b is located within the thickness range of the heating tube 120, which can facilitate the connection of the water outlet section 136b with the external user end, thereby facilitating the installation of the entire heating component 100.

[0079] 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 .

[0080] Among them, the heating pipe 120 is the heating body 124b of the entire heating component 100, which is 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 component 100. The diameter of the water outlet pipe 130 is smaller than the radius of the heating pipe 120, so it 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, since the diameter of the water outlet pipe 130 is relatively small, the water flow speed in the water outlet pipe 130 is relatively small. When the external cold water enters the heating pipe 120 from the water inlet pipe 110, the water flow can stay in the heating pipe 120 for a longer time, increasing the heat exchange time with the heating pipe 120, so that the water can fully exchange heat with the heating pipe 120, thereby ensuring the water temperature flowing out of the water outlet pipe 130 and improving the user experience.

[0081] Specifically, the diameters of all parts of the water outlet pipe 130 are the same, that is, the diameters of the transition portion 132, the bending portion 134 and the water outlet portion 136 are all smaller than the radius of the heating pipe 120. In other words, 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.

[0082] In addition, since the first connecting segment 134a and the third connecting segment 134c are overlapped in the thickness direction of the heat pipe 120, that is, in the thickness direction of the heat pipe 120, the diameter of the first connecting segment 134a, the diameter of the third connecting segment 134c and the distance between the first connecting segment 134a and the third connecting segment 134c are the thickness of the entire bending portion 134. Since the diameters of the first connecting segment 134a and the third connecting segment 134c are both smaller than the radius of the heat pipe 120, that is, the sum of the diameters of the first connecting segment 134a and the third connecting segment 134c is smaller than the diameter of the heat pipe 120, and the distance between the first connecting segment 134a and the third connecting segment 134c is not too large, the thickness of the entire bending portion 134 is substantially equal to the thickness of the heat pipe 120 or the thickness of the bending portion 134 is slightly larger than the thickness of the heat pipe 120. This method can reduce the portion of the bending portion 134 protruding from the heat pipe 120 as much as possible, and can also avoid increasing the thickness of the entire heating component 100 as much as possible.

[0083] In some embodiments, the transition portion 132 is directly connected to the first water outlet 121 b of one of the heating pipes 120 , and the transition portion 132 extends along the first direction.

[0084] The transition portion 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 portion 132. The transition portion 132 extends along the first direction. That is, the transition portion 132 extends along the width direction of the heating component 100. Since the length of the transition portion 132 is very short, the size of the entire heating component 100 in the width direction is basically not increased.

[0085] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, there are multiple heating tubes 120, and the multiple heating tubes 120 are arranged side by side in sequence. 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.

[0086] 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, which means that the multiple heating tubes 120 are connected in parallel, that is, the heating of the multiple heating tubes 120 is independent of each other, and the water in the water inlet pipe 110 is heated by one of the heating tubes 120 and becomes hot water and enters the water outlet pipe 130. In other words, the multiple heating tubes 120 can heat different water at the same time, and the amount of hot water in the water outlet pipe 130 can be increased at the same time, and the amount of water discharged from the third water outlet 131b can be increased in a short time, so that the user can use enough hot water in a short time, thereby improving the user's comfort.

[0087] At the same time, multiple heating tubes 120 are connected in parallel, and each heating tube 120 only needs to bear a part of the water heating. 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.

[0088] The axis of the first connecting tube 140 is offset from the middle of the heating tube 120, indicating that the axis of the first connecting tube 140 does not pass through the middle of the heating tube 120, that is, it can be considered that the first connecting tube 140 is eccentrically arranged on the first connecting tube 140. The axis of the first connecting tube 140 can also indicate the flow direction of water entering the heating tube 120, that is, the water outlet direction of the first connecting tube 140. The axis of the first connecting tube 140 is offset from the middle of the heating tube 120, indicating that the water flow entering the heating tube 120 from the first connecting tube 140 will not When passing through the middle of the heating tube 120, it collides with the inner wall of the heating tube 120, thereby forming a spiral water path inside the heating tube 120, which can achieve full mixing of the liquid in the heating tube 120 and make the outlet water temperature uniform. In addition, the flow path of the water flow in the heating tube 120 is increased, and the heat exchange time between the water flow and the heating tube 120 is increased, which can effectively take away the heat on the surface of the heating tube 120, improve the heat exchange efficiency, reduce the heat density of the heating tube 120 when working, and can extend the service life of the heating tube 120 and reduce the failure rate of the heating tube 120.

[0089] At the same time, the water flow forms a spiral water path inside the heating tube 120, which can increase the flow path of the water flow in the heating tube 120, increase the heat exchange time between the water flow and the heating tube 120, and make full use of the heat of the heating tube 120, so that the water flow can reach the target temperature value when flowing out of the heating tube 120 from the first water outlet 121b, thereby improving the heating effect of the entire heating component 100.

[0090] The middle of the heat pipe 120 refers to the position of a cylinder formed with the center of the heat pipe 120 as the center and a radius of one-half or one-third of the smallest size. For example, when the heat pipe 120 is a cylinder, the middle of the heat pipe 120 refers to the area of ​​a cylinder formed with the center of the heat pipe 120 as the center and a radius of one-half or one-third of the radius. When the heat pipe 120 is a cylinder, the axis of the first connecting pipe 140 is offset from the middle of the heat pipe 120, which can also be considered as the axis of the first connecting pipe 140 being offset from the center of the heat pipe 120.

[0091] In some embodiments, the heat pipe 120 includes a shell 122 and a cover 128 connected to the shell 122 , the first water inlet 121 a is disposed on the cover 128 , the first water outlet 121 b is disposed on the shell 122 , and the first connecting pipe 140 is connected to the cover 128 .

[0092] Among them, the shell 122 and the cover body 128 are split structures, the cover body 128 is arranged at the end of the shell 122, the cover body 128 can be connected to the shell 122 by means of threads, and the heating components and other components are mainly installed in the shell 122. If the heating components in the shell 122 fail or the shell 122 is blocked, the cover body 128 can be removed from the shell 122 to facilitate the maintenance of the components in the shell 122.

[0093] 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.

[0094] 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 .

[0095] In addition, when the water flows from the first connecting pipe 140 into the cover 128, a vortex can be formed in the heating tube 120 during the process of the water flowing from bottom to top, so that the water in the heating tube 120 can be fully mixed and the temperature of the water can be relatively uniform. In some embodiments, along the flow path direction away from the second water inlet 112, the opening areas of the multiple water inlet pipes 110 decrease in sequence.

[0096] Among them, the flow direction refers to the direction of water flow in the water inlet pipe 110, the heating tube 120, the first connecting tube 140, and the second water outlet 114 are respectively multiple and one-to-one corresponding, and the water inlet pipe 110 is connected to different heating tubes 120 through different first connecting tubes 140, that is, multiple first connecting tubes 140 are arranged on the water inlet pipe 110 in sequence, and 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 tubes 120, and the water flow flowing through the first first connecting tube 140 needs to supply water to the first heating tube 120 and all subsequent heating tubes 120. In order to ensure that the amount of heated water for each heating tube 120 is the same as much 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 subsequent heating tubes 120 can be roughly the same.

[0097] For example, there are three heating tubes 120 in total, and there are also three first connecting tubes 140. The leftmost heating tube 120 is closest to the second water inlet 112. The order of the three heating tubes 120 from left to right is 1, 2, and 3 respectively. Similarly, the order of the first connecting tubes 140 connected to the three heating tubes 120 from left to right is also 1, 2, and 3 respectively. In the water inlet pipe 110, the amount of water flowing through the first first connecting tube 140 needs to supply the amount of water of the first heating tube 120 and the amount of water of the second and third heating tubes 120, while the amount of water flowing through the second connecting tube needs to supply the amount of water of the second and third heating tubes 120, and the amount of water flowing through the third connecting tube only needs to supply the amount of water of the third heating tube 120. In other words, the opening area of ​​the water inlet pipe 110 at the first connecting tube 140 is larger than the opening area at the second first connecting tube 140 and the opening area at the third first connecting tube 140.

[0098] This method can ensure as much as possible that under different water flows or pressures, the multiple heating tubes 120 can have approximately the same amount of water, and can make the heat exchange performance and water outlet temperature of the entire heating component 100 more balanced.

[0099] In some embodiments, multiple second water outlets 114 are located at the same height. This means that the multiple second water outlets 114 have the same height, and after the water in the water inlet pipe 110 flows from the second water inlet 112 to the second water outlet 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 to flow into different first connecting pipes 140 roughly the same, so that water can flow quickly into different heating tubes 120, and avoids as much as possible the uneven flow rate of different second water outlets 114 causing different water flow in the heating tube 120, and the situation of dry burning due to the small water flow in a certain heating tube 120.

[0100] In some embodiments, the plurality of first water inlets 121c are located at the same height.

[0101] The multiple first water inlets 121c being located at the same height means that the first water inlets 121c of the multiple heating tubes 120 are located at the same height. When the heating component 100 is installed and in use, the axial direction of the heating tube 120 is substantially vertical, and in the axial direction of the heating tube 120, that is, in the vertical direction, the first water inlets 121c of the multiple heating tubes 120 are located at the same height.

[0102] The first water inlets 121c of the multiple heating tubes 120 are located at the same height. When water flows into different heating tubes 120 from different first connecting tubes 140, since the multiple first water inlets 121c are located at the same height, the resistance of the combination of different first connecting tubes 140 and heating tubes 120 is roughly the same, so that the water flow can quickly enter the different heating tubes 120 and can be quickly distributed in each heating tube 120, avoiding the situation where the heating tube 120 that is far away from the second water inlet 112 has no water in the heating tube 120 and dry-burns when the heating component 100 is just started.

[0103] At the same time, since the multiple first water inlets 121c are located at the same height, that is, the multiple first water inlets 121c are located on the same horizontal line, the resistance entering the heating tube 120 in different combinations of the first connecting tube 140 and the heating tube 120 is roughly the same, so that the water flow can always maintain a stable flow rate to flow into each heating tube 120, thereby improving the working stability of the entire heating component 100.

[0104] See also Figure 6 In some embodiments, the first water outlets 121 b of the plurality of heating tubes 120 are connected and communicated in sequence, and the first water outlet 121 b of one of the heating tubes 120 is directly communicated with the water outlet pipe 130 .

[0105] The first water outlets 121b of the plurality of heating tubes 120 are connected in sequence, that is, the water inlet pipes 110 of the plurality of heating tubes 120 are interconnected. After the water in different heating tubes 120 flows to their own first water outlets 121b, it can flow between the first water outlets 121b of the plurality of heating tubes 120. If one of the heating tubes 120 is blocked or damaged and cannot work normally, the water can flow to the first water outlet 121b of the adjacent heating tube 120, and be discharged through the water outlet pipe 130 after being heated by the heating tube 120. This can alleviate the problem of excessive water pressure in the branch caused by a fault blockage of one of the heating tubes 120, and can avoid the problem of pipe burst due to blockage.

[0106] That is to say, in the embodiment of the present application, the plurality of heating tubes 120 are connected in parallel, but the first water outlets 121b of the plurality of heating tubes 120 are connected in series. Through this connection method, the first water outlets 121b of the plurality of heating tubes 120 are connected, which can reduce the problem of blockage of one of the heating tubes 120 causing the water pressure of the heating tube 120 to increase and cause the tube to burst. At the same time, the plurality of heating tubes 120 are connected in parallel, and the plurality of heating tubes 120 can heat different water at the same time, and the water output of the water outlet pipe 130 can be increased at the same time. The water output from the third water outlet 131b can be increased in a short time, so that the user can use enough hot water in a short time, thereby improving the user's comfort.

[0107] In some embodiments, there may be two first water outlets 121b, the two first water outlets 121d are located at the same end of the heating tube 120, the heating component 100 also includes a plurality of second connecting tubes 150, the first water outlets 121d of two adjacent heating tubes 120 are connected through the second connecting tubes 150, and the third water inlet 131a is connected to any one of the second connecting tubes 150 or to one of the first water outlets 121d.

[0108] Among them, a plurality of heating tubes 120 are arranged in sequence, and 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. Two adjacent heating tubes 120 are connected respectively through two first water outlets 121d. Specifically, the first water outlets 121d of two adjacent heating tubes 120 can be directly connected, or connected through a second connecting tube 150, and the second connecting tube 150 can connect two adjacent heating tubes 120, so that there is a certain gap between the two adjacent heating tubes 120, so as to avoid the two adjacent heating tubes 120 from affecting each other during the working process. At the same time, a certain gap between the two adjacent heating tubes 120 can facilitate the heat dissipation of each heating tube 120 and improve the service life of the heating tube 120.

[0109] In some embodiments, the plurality of second connecting tubes 150 are connected in series through the heating tubes 120. That is, the plurality of second connecting tubes 150 and the first water outlets 121b of the plurality of heating tubes 120 are alternately connected, and the plurality of second connecting tubes 150 and the first water outlets 121b of the plurality of heating tubes 120 are alternately connected in series, so that the first water outlets 121b of the plurality of heating tubes 120 are connected in series, and after water enters the first water outlet 121b of one of the heating tubes 120, it can flow among the plurality of heating tubes 120, and the second connecting tubes 150 play the role of connecting the first water outlets 121b of the heating tubes 120 in series, and can also make two adjacent heating tubes 120 spaced apart.

[0110] The third water inlet 131a may be connected to any one of the second connecting pipes 150, or may be connected to the first water outlet 121d not connected to the second connecting pipe 150, as long as it can be connected to multiple first water outlets 121b.

[0111] In some embodiments, in a direction approaching the third water inlet 131 a , the opening areas of the plurality of first water outlets 121 d increase sequentially.

[0112] Similarly, the water flow direction in the same heating tube 120 is also close to the third water inlet 131a. The first water outlet 121d close to the third water inlet 131a can be understood as the outlet, and the first water outlet 121d far away 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 first water outlets 121b of the heating tube 120 are to the third water inlet 131a, the greater the water flow rate collected by the first water outlets 121b. 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 time, so that each heating tube 120 can be reasonably utilized to improve the heating energy efficiency of the entire heating component 100.

[0113] See also Figure 7 and Figure 8 In some embodiments, the heat pipe 120 includes: a shell 122, a heating element 123, an upper cover 124 and a sealing element 125, the shell 122 has a accommodating cavity 122a and an opening 122b connected to the accommodating cavity 122a, and the shell 122 has a first connecting portion 126; the heating element 123 is installed in the accommodating 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 sealing element 125 is sleeved on the upper cover 124, is spaced apart from the second connecting portion 127, and contacts the inner wall of the shell 122.

[0114] Among them, the shell 122 is the main body 124b of the entire heating tube 120, which provides a foundation for installing components such as the heating element 123 and the sealing element 125, and can accommodate and protect the heating element 123 and other structures. The heating element 123 is arranged inside the shell 122 to heat the water entering the shell 122, and after being heated to the set temperature, it is discharged to the outside of the shell 122.

[0115] The accommodating chamber 122a is mainly used to accommodate water, so the accommodating chamber 122a needs to be a sealed chamber. The upper cover 124 covers the opening 122b, and needs to seal the gap between the upper cover 124 and the shell 122. The sealing member 125 is installed on the upper cover 124 to seal the gap between the upper cover 124 and the shell 122. The first connecting portion 126 cooperates with the second connecting portion 127, so that the upper cover 124 can be installed in the opening 122b of the shell 122. Since the first connecting portion 126 needs to cooperate with the second connecting portion 127, they will be subject to mutual force during the mutual cooperation process. If the sealing member 125 contacts the second connecting portion 127, during the cooperation process of the second connecting portion 127, the sealing member 125 may be deformed due to the force of the first connecting portion 126, resulting in a gap between the upper cover 124 and the shell 122, thereby causing water leakage.

[0116] 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.

[0117] 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.

[0118] See also Fig. 9 and Fig.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 .

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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 .

[0125] 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.

[0126] In some embodiments, the partition 124d is arranged in a ring around the main body 124b, and the cover 124c is arranged at one end of the main body 124b. The installation groove 124a formed by the partition 124d, the main body 124b and the cover 124c is also an annular structure. The installation groove 124a is arranged in a ring around the outer periphery of the main body 124b, so that the seal 125 is also arranged in a ring around the outer periphery of the main body 124b, which can contact and resist the inner wall of the shell 122, thereby sealing the gap between the main body 124b and the inner wall of the shell 122.

[0127] The cross sections of the cover plate 124c, the main body 124b and the partition plate 124d are all circular, the main body 124b has the smallest diameter, the cover plate 124c has the largest diameter, and the partition plate 124d has a diameter greater than the diameter of the main body 124b and smaller than the diameter of the cover plate 124c. The diameter of the cover plate 124c may be slightly larger than the size of the opening 122b of the accommodating cavity 122a, so as to completely cover the opening 122b.

[0128] In some embodiments, the projection of the second connection portion 127 on the partition 124d is located inside the partition 124d. The second connection portion 127 is disposed around the periphery of the partition 124d, and the partition 124d is also disposed around the periphery of the main body 124b. The projection of the second connection part 127 on the partition 124d is located inside the partition 124d, which means that the height of the second connection part 127 protruding from the main body 124b is less than the height of the partition 124d protruding from the main body 124b. During the cooperation between the first connection part 126 and the second connection part 127, the first connection part 126 will extend to the bottom of the partition 124d and cooperate with the second connection part 127. The partition 124d can isolate the first connection part 126 and the second connection part 127. During the cooperation between the first connection part 126 and the second connection part 127, the first connection part 126 basically does not contact the seal 125, and the seal 125 is basically not subjected to other forces except the shell 122, thereby improving the sealing effect of the seal 125.

[0129] In some embodiments, the mounting groove 124a is arranged in an annular manner on the upper cover 124, and at least a portion of the sealing member 125 protrudes out of the mounting groove 124a. The sealing member 125 is an annular structure, and the sealing member 125 is installed in the mounting groove 124a, that is, arranged in an annular manner in the mounting groove 124a. The portion of the sealing member 125 protruding out of the mounting groove 124a can facilitate the sealing member 125 to abut against the inner wall of the housing 122, and the portion of the sealing member 125 protruding out of the mounting groove abuts against the inner wall of the housing 122, so as to seal the gap between the upper cover 124 and the housing 122, thereby reducing the risk of water leakage of the entire heating pipe 120 and improving the sealing performance of the entire heating pipe 120.

[0130] In some embodiments, in the second connection portion 127 and the mounting groove 124a, the second connection 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 connection portion 127 is disposed below the mounting groove 124a, that is, the second connection portion 127 is disposed below the sealing member 125, the heating element 123 is installed in the accommodating cavity 122a, and the sealing member 125 can seal the upper part of the entire accommodating cavity 122a.

[0131] In some embodiments, the accommodating cavity 122a has a first mounting section 122c and a second mounting section 122d that are interconnected, the opening area of ​​the second mounting section 122d is larger than the opening area of ​​the first mounting section 122c, the heating element 123 is disposed in the second mounting section 122d, and the sealing element 125 is disposed in the first mounting section 122c.

[0132] The first installation section 122c and the second installation section 122d are stepped, the opening area of ​​the second installation section 122d is larger, and the opening area of ​​the first installation section 122c is smaller. The sealing member 125 and the upper cover 124 are arranged in the first installation section 122c, so that the upper cover 124 and the sealing member 125 can seal the opening 122b of the entire accommodating cavity 122a.

[0133] In some embodiments, the first connection portion 126 is disposed in the accommodating cavity 122a, and the second connection portion 127 is disposed on the outer periphery of the upper cover 124. The first connection portion 126 and the second connection portion 127 are both threads, the first connection portion 126 is an internal thread disposed in the accommodating cavity 122a, and the second connection portion 127 is an external thread disposed in the outer periphery of the upper cover 124. The internal thread can be formed together with the housing 122.

[0134] In some embodiments, the shell 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 a 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.

[0135] Among them, the first installation section 122c includes a first sub-segment 122g and a second sub-segment 122h which are interconnected. The first sub-segment 122g is arranged close to the second installation section 122d, and the second sub-segment 122h is arranged away from the first installation section 122c. The opening area of ​​the first sub-segment 122g is smaller than the opening area of ​​the second sub-segment 122h. The cover body is installed in the second sub-segment 122h. The first connecting part 126 is arranged on the inner wall of the first sub-segment 122g. The second connecting part 127 is installed in the first sub-segment 122g and assembled with the first connecting part 126.

[0136] In some embodiments, the diameter of the second sub-segment 122h is 20mm to 50mm, and the thickness of the second sub-segment 122h is 4mm to 8mm. The thickness of the shell 122 corresponding to the second sub-segment 122h is 1mm to 4mm. 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 force of the first connecting portion 126. Therefore, the width of the first sub-segment 122h does not need to be set too thick, and 4mm to 8mm is sufficient. Similarly, the corresponding shell 122 does not need to be set too thick, and 1mm to 4mm is sufficient. As for the diameter, it can be adapted to the seal 125.
