[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] The utility model provides a heater and a water heater.

[0033] See also Figures 4 to 6 In one embodiment of the utility model, the water heater comprises an inner tank 10 and a water pipe 20, an anode member 30 and a heater installed on the inner tank 10. At least one of the water pipe 20 and the anode member 30 is connected to the bottom of the inner tank 10 and extends into the inner tank 10. The central axis of the installation part 100 of the heater is parallel to and close to the central axis of the inner tank 10. The inner tank 10 is provided with an installation opening 11, and the installation opening 11 is used for installing the installation part 100 of the heater.

[0034] Specifically, the water pipe 20 includes an inlet pipe 21 and an outlet pipe 22. To ensure the water inlet and outlet effects, the end of the outlet pipe 22 will be close to the top of the inner tank 10, that is, the outlet pipe 22 will generally pass through the central axis of the inner tank 10, and the end of the inlet pipe 21 will be close to the central axis of the inner tank 10. In this way, the inlet of the outlet pipe 22 is higher than the outlet of the inlet pipe 21 to protect the heater and ensure that the water level of the inner tank 10 can be maintained above the heating pipe of the heater even when the water is cut off.

[0035] The anode component 30 can be installed inside the inner liner 10 or outside the inner liner 10. In this embodiment, the anode component 30 is installed inside the inner liner 10 as an example. To ensure the protection of the anode component 30 on the inner liner 10, the anode component 30 is generally higher than the central axis of the inner liner 10. The anode component 30 can be configured as a magnesium rod or an aluminum rod or a zinc rod or a zinc-magnesium alloy rod, etc., so that the metal activity of the anode component 30 is higher than the material used for the water heater tank 10 or the heating element. The anode component 30 will preferentially undergo an oxidation reaction in the water, and by "sacrificing" itself, it attracts corrosive ions in the water to form a protective film, thereby effectively preventing the water heater tank 10 and the heating element from being corroded, thereby extending the overall service life of the water heater. In addition, the ions released during the reaction of the anode component 30 can help soften the water quality, reduce the tendency of minerals such as calcium and magnesium in the water to form hard scale, maintain heating efficiency, and reduce energy waste and equipment damage caused by scale accumulation. In addition, the anode component 30 can also react with impurities in the water to maintain the relative balance of water quality inside the water heater and reduce erosion of the tank 10 and pipes.

[0036] Due to the above-mentioned installation positions of the water pipe 20 and the anode member 30, the heating tube structure of the existing heater is easy to interfere with the water pipe 20 or the anode member 30, which makes it inconvenient to disassemble and assemble the heater.

[0037] See also Figures 1 to 3 In one embodiment of the present utility model, the heater comprises:

[0038] The mounting portion 100; and

[0039] The first heating tube 200 includes a first extension section 210 and a second extension section 220 connected in sequence, wherein the first extension section 210 is connected to the mounting portion 100, and at least a portion of the first extension section 210 extends obliquely relative to the central axis of the mounting portion 100, and the second extension section 220 is bent relative to the first extension section 210, and the projections of the first extension section 210 and the second extension section 220 along the central axis of the mounting portion 100 are arranged at a first angle A.

[0040] In the technical solution of the utility model, at least part of the first extension section 210 extends obliquely relative to the central axis of the mounting portion 100, so that the bending position of the second extension section 220 deviates from the central axis of the mounting portion 100, and the second extension section 220 is bent and then extends obliquely relative to the first extension section 210, so that the above projection is at a first angle A, thereby making the second extension section 220 not pass through the central axis of the mounting portion 100, so that the second extension section 220 as a whole can deviate from the central axis of the mounting portion 100. It can be understood that after the heater is installed on the water heater, the central axis of the mounting portion 100 will be parallel to and close to the central axis of the inner tank 10. In this way, after the heater is installed on the inner tank 10 of the water heater through the mounting portion 100, the second extension section 220 can have a sufficient extension in the radial direction of the inner tank 10, and the second extension section 220 can be set away from the central axis of the inner tank 10, so that the second extension section 220 will not interfere with the anode member 30 or the water pipe 20 and other components. In addition, the first extension section 210 and the second extension section 220 are set at an angle, so that the heater can be installed at a certain angle, so that the first extension section 210 and the second extension section 220 are located on the same side of the anode member 30 and the water pipe 20, and the heater as a whole will not interfere with related components. When assembling the water heater, there is no need to pay attention to the installation order of the heater and the water pipe 20, the anode member 30 and other components. When the heater is maintained later, it can also be easily disassembled and assembled without being interfered with by the water pipe 20, the anode member 30 and other components.

[0041] In one embodiment, see Figure 3 , the first angle A is an acute angle. That is, the first extension section 210 is inclined away from the central axis of the mounting portion 100, and a portion of the second extension section 220 close to the first extension section 210 extends in a direction close to the central axis of the mounting portion 100, and the second extension section 220 continues to extend away from the central axis of the mounting portion 100. In this way, the extension length of the second extension section 220 can be increased, which is conducive to increasing the heating range of the second extension section 220, and the second extension section 220 can span from one side of the central axis of the inner pot 10 to the other side, which is conducive to ensuring the uniformity of the heater heating the water in the inner pot 10.

[0042] Specifically, please combine Figures 1 to 3 and Figure 6 After the heater is installed on the inner pot 10, the inclined extension portion of the first extension section 210 is configured to extend downwardly, and the second extension section 220 is bent upward relative to the first extension section 210. In this way, the second extension section 220 is partially located above the central axis of the inner pot 10 and partially located above the central axis of the inner pot 10, which can take into account the heating of water in the upper and lower positions of the inner pot 10, which is conducive to improving the uniformity of the heater heating the water.

[0043] Of course, in other embodiments, the first angle A can also be configured as an obtuse angle, that is, the second extension portion continues to bend in the direction of the first extension portion deviating from the central axis of the mounting portion 100. After the heater is installed on the water heater, it is manifested as: the inclined extending portion of the first extension section 210 is inclined upward, and the second extension section 220 is bent upward relative to the first extension section 210; or, the inclined extending portion of the first extension section 210 is inclined downward, and the second extension section 220 is bent downward relative to the first extension section 210.

[0044] In one embodiment, the first angle A is 20 to 45 degrees. When the first angle A is within this range, the processing of the first heating tube 200 can be facilitated while ensuring the structural strength of the first heating tube 200. In particular, the first angle A within this range combined with the inclination of the first extension section 210 can facilitate controlling the distance between the second extension section 220 and the anode member 30 within a suitable range to ensure that the first heating tube 200 and the anode member 30 can function independently. The first angle A is preferably 25 to 30 degrees.

[0045] In one embodiment, see Figure 1 and Figure 3 , the minimum distance D1 between the central axis of the mounting portion 100 and the second extension section 220 is 16 mm to 59 mm. In this way, after the heater is installed in the inner tank 10 of the water heater, the distance between the second extension section 220 of the first heating tube 200 and the central axis of the inner tank 10 will also be maintained within the above range, and the components such as the water pipe 20 and the anode member 30 are arranged corresponding to the central axis of the inner tank 10, that is, the distance between the second extension section 220 and the anode member can be within a suitable range. In particular, if Figure 6 As shown, when the second extension section 220 and the water pipe 20 and the anode member 30 are arranged in parallel, the minimum distance D2 between the second extension section 220 and the anode member 30 will be between 4 mm and 47 mm. Within the above range, the second extension section 220 and the water pipe 20 or the anode member 30, as well as the second extension section 220 and the inner wall of the inner pot 10 can maintain a sufficient distance to ensure that the first heating tube 200 and the anode member 30 can function independently. At the same time, the appropriate spacing helps the water to form a more reasonable flow path inside the inner pot 10, ensuring that the water flow can fully contact the anode member 30 and the first heating tube 200, making the heating more uniform, and also conducive to the uniform distribution of the metal ions released by the anode member 30 in the water, improving the protection effect and water quality treatment effect. Among them, the above minimum distance D1 is preferably 25 mm to 44 mm, and the minimum distance D2 between the second extension section 220 and the anode member 30 will be correspondingly between 13 mm and 22 mm.

[0046] In one embodiment, see Figure 1 and Figure 2The second extension section 220 includes at least two folded tube sections. Specifically, the two connected tube sections are connected in a U-shape, so that the effective heating length of the second extension section 220 can be increased without occupying too much space, thereby improving the heating capacity of the second extension section 220, which is conducive to improving the heating efficiency of the heater.

[0047] In one embodiment, see Figure 2 , the first extension section 210 includes a first connection section 211, an inclined section 213 and a second connection section 212 connected in sequence, the extension directions of the first connection section 211 and the second connection section 212 are parallel to the central axis of the mounting portion 100, and the inclined section 213 extends obliquely relative to the central axis of the mounting portion 100. In this way, the extension direction of the first connection section 211 allows the first connection section 211 to be conveniently installed on the mounting portion 100, and at the same time, the connection strength between the first connection section 211 and the mounting portion 100 can be guaranteed; the extension direction of the second connection section 212 allows the bending amount of the second extension section 220 to be small, which is convenient for the bending process of the second extension section 220, and at the same time, the bending angle formed by the two is not too small, and the structural strength of the connection between the second connection section 212 and the second extension section 220 can be guaranteed, and the connection is not easy to break. Of course, in other embodiments, it is also possible that, under the premise of ensuring the structural strength, the first extension section 210 extends obliquely as a whole, or the inclined section 213 is directly connected to the mounting portion 100 or the second extension section 220.

[0048] In one embodiment, see Figures 1 to 3 , the heater further comprises a second heating tube 300, the second heating tube 300 and the first extension section 210 extend in parallel, and the second extension section 220 bends in a direction away from the second heating tube 300. Specifically, the sections of the second heating tube 300 extend in the direction of the first connecting section 211, the inclined section 213 and the second connecting section 212 in sequence, so that the second heating tube 300 and the first extension section 210 are parallel, and the second heating tube 300 and the first extension section 210 can heat water at different positions on the opposite sides of the first extension section 210, which is conducive to improving the heating capacity of the heater. After the heater is installed on the inner tank 10, the second heating tube 300 will be located below the first extension section 210. In this way, when the water in the inner tank 10 is heated by the first heating tube 200, the upper half of the water in the inner tank 10 can be quickly heated, shortening the heating time so that the user can quickly use the hot water, and when the water in the inner tank 10 is heated by the second heating tube 300, the whole tank water can be heated, which is convenient for providing more hot water to the user.

[0049] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
