Description

Technical Field

[0001] This utility model relates to a water heater. Background Technology

[0002] The internal water heater of the coffee machine includes a water pipe and a heating element. The heating element is wrapped around the outer circumference of the water pipe, and the two ends of the water pipe are the inlet and the outlet, respectively.

[0003] However, the heating power of existing water heaters is generally fixed. If water heaters with different power are needed, it is necessary to make a separate mold to manufacture the corresponding water heater, which undoubtedly increases the development cost.

[0004] For example, the patent with publication number CN213713537U discloses a flow-through water heater, which includes a spiral water pipe and a heating pipe. The heating pipe is welded into the inner hole formed by the spiral shape of the spiral water pipe, and the two ends of the spiral water pipe serve as the water inlet and the water outlet, respectively.

[0005] The heating power of the water heater in the above technology is fixed, and the heating power of the water heater cannot be increased on the original basis. If a water heater with greater power is needed, it is necessary to make a new mold and manufacture it, which increases the development cost. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a water heater whose heating power can be increased by assembly.

[0007] The technical solution adopted by this utility model to solve the problem is: a water heater, including a main body, the main body including a water pipe and a heating pipe, the heating pipe being wound around the outer periphery of the water pipe, the water pipe having a first end and a second end, characterized in that: it further includes a first end cap, the first end being provided with a first flange interface, the first flange interface being detachably connected to the first end cap, the first end cap being provided with a first water hole, the first water hole being used for water inlet or outlet, the first water hole being connected to the water pipe.

[0008] As a further improvement to the above technical solution, a second end cap is also included. The second end is provided with a second flange interface, which is detachably connected to the second end cap. A second water hole is provided on the second end cap, and the second water hole is connected to the water pipe.

[0009] As a further improvement to the above technical solution, the first flange interface is adapted to the second flange interface, and the first end of the water pipe can be connected to the first end or the second end of another water pipe.

[0010] As a further improvement to the above technical solution, a first flange gasket is crimped between the first flange interface and the first end cover; a second flange gasket is crimped between the second flange interface and the second end cover.

[0011] As a further improvement to the above technical solution, a first recess is provided on the inner side of the first flange interface, and a first recess corresponding to the first recess is provided on the first flange gasket, with the first recess being embedded in the first recess; a second recess is provided on the inner side of the second flange interface, and a second recess corresponding to the second recess is provided on the second flange gasket, with the second recess being embedded in the second recess.

[0012] As a further improvement to the above technical solution, an aluminum layer is provided between the water pipe and the heating pipe.

[0013] The beneficial effects of this utility model are as follows: This utility model sets a first flange interface at the first end of the water pipe. The first flange interface is detachably connected to the first end cover. The water inlet or outlet is set on the first end cover. When it is necessary to increase the heating power of the electric heating element, another main body can be added to the first flange interface. The water pipe between the two main bodies is fixedly connected together through the first flange interface, thereby increasing the heating power of the electric heating element. No additional mold is required, reducing development costs. Attached Figure Description

[0026] Reference Figures 1 to 6 A water heater includes a main body comprising a water pipe 1 and a heating pipe 2. The water pipe 1 is cylindrical, and the heating pipe 2 is wound around the outer circumference of the water pipe 1. The water pipe 1 has a first end and a second end, and also includes a first end cap 3. The first end is provided with a first flange interface 11, which is detachably connected to the first end cap 3. The first end cap 3 is provided with a first water hole 31 for water inlet or outlet, and the first water hole 31 communicates with the water pipe 1. When it is necessary to increase the heating power of the water heater, the first end cap 3 can be removed first, and another main body can be connected to the first end. The two main bodies are fixedly connected together through the first flange interface 11, thereby increasing the overall heating power.

[0027] Furthermore, the two main bodies can be controlled independently, and in actual heating, they can form a heating mode of upper cooling and lower heating or upper heating and lower cooling to adapt to different application scenarios and increase the application range of the water heater.

[0028] In a preferred embodiment, a second end cap 4 is further included. The second end cap 4 has a second flange interface 12, which is detachably connected to the second end cap 4. The second end cap 4 has a second water hole 41, which communicates with the water pipe 1. The first water hole 31 acts as an inlet, and the second water hole 41 acts as an outlet. Water flows sequentially through the first water hole 31, the water pipe 1, and the second water hole 41. Figure 6 As shown, by setting detachable end caps at both ends of the water pipe 1, the main body can be installed at both ends, further increasing the heating power.

[0029] In a preferred embodiment, such as Figures 3 to 5 As shown, the second end is provided with the first flange interface 11 and the second flange interface 12 adapted together. The first end of the water pipe 1 can be connected to the first end or the second end of another water pipe 1, so that the two main bodies can be connected end to end, head to head, or tail to tail. It should be noted that if both ends of the spliced ​​main body are the first water hole 31 or the second water hole 41, then one of them serves as the water inlet and the other as the water outlet.

[0030] In a preferred embodiment, a first flange gasket 5 is crimped between the first flange interface 11 and the first end cover 3; a second flange gasket 6 is crimped between the second flange interface 12 and the second end cover 4 to improve sealing.

[0031] In a preferred embodiment, a first recess 111 is provided on the inner side of the first flange interface 11, and a first recess 51 corresponding to the first recess 111 is provided on the first flange gasket 5, with the first recess 51 embedded in the first recess 111; a second recess (with the same form as the first recess 111) is provided on the inner side of the second flange interface 12, and a second recess 61 corresponding to the second recess is provided on the second flange gasket 6, with the second recess 61 embedded in the second recess, further improving the sealing performance.

[0032] In a preferred embodiment, a die-cast aluminum layer is provided between the water pipe 1 and the heating pipe 2 to increase the heat transfer efficiency. It should be noted that the relationship between the flange interface and the water pipe 1 should be understood as follows: the positions of the first flange interface 11 and the second flange interface 12 are located at the first end and the second end of the water pipe 1, and the setting position of the flange interface is relatively fixed with the positions of the first end and the second end. That is, the flange interface can be integrally set on the die-cast aluminum on the outer periphery of the water pipe 1 (the specific form shown in this utility model), or it can be integrally set on the body of the water pipe 1, or it can be other methods that can achieve the above functions.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
