[0026] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1:

[0028] This embodiment provides a U-shaped water heater, such as Figure 1-Figure 8 As shown, it includes a heat-conducting frame 1, a water pipe 2 and a heating pipe 3. The heating pipe 3 is U-shaped. The heat-conducting frame 1 has a first end 14 and a second end 15. Preferably, the heat-conducting frame 1 is a U-shaped structure, and the first end 14 and the second end 15 are respectively arranged on both sides of the U-shaped opening of the heat-conducting frame 1.

[0029] The heat-conducting frame 1 is provided with a first through hole 11 adapted to the heat-conducting tube 3, and a second through hole 12 and a third through hole 13 are respectively provided on the upper and lower sides of the first through hole 11. The second through hole 12 and the third through hole 13 are arranged parallel to the first through hole 11, and the first through hole 11, the second through hole 12 and the third through hole 13 extend from the first end 14 to the second end 15 of the heat-conducting frame 1. The lengths of the first through hole 11, the second through hole 12 and the third through hole 13 may be equal. Preferably, as Figure 3 As shown, the vertical distances between the first through hole 11 and the third through hole 13 and the second through hole 12 are equal.

[0030] The heating tube 3 is disposed through the first through hole 11, and the water tube 2 is disposed through the second through hole 12 and the third through hole 13. The heat emitted by the heating tube 3 can be evenly transferred to the water tubes 2 located at the upper and lower sides.

[0031] The U-shaped water heater in this embodiment is heated by the heating tube 3, and the heat is transferred to the entire heat-conducting frame 1. The heat-conducting frame 1 transfers the heat to the water pipe 2. Since the water pipe 2 is distributed on the upper and lower sides of the heating tube 3, the heating tube 3 is easier to transfer heat to the water pipe 2, and the heat transfer is more uniform, thereby improving the heating efficiency of the water pipe 2.

[0032] As a preferred embodiment, the water pipe 2 is provided with a water inlet 24 and a water outlet 25 at the first end 14 of the heat conducting frame 1, and the water inlet 24 and the water outlet 25 are respectively provided corresponding to the second through hole 12 and the third through hole 13. After the water pipe 2 penetrates the second through hole 12, it penetrates the third through hole 13 from the second end 15, and then penetrates to the first end 14 and then passes out of the heat conducting frame 1.

[0033] As a preferred embodiment, the water pipe 2 includes a first tube body 21 and a second tube body 22, and the first tube body 21 and the second tube body 22 are respectively arranged through the second through hole 12 and the third through hole 13. The first tube body 21 and the second tube body 22 are respectively provided with a water inlet 24 and a water outlet 25 at the first end 14 of the heat conducting frame 1, and the first tube body 21 and the second tube body 22 are connected at the second end 15 of the heat conducting frame 1 through an arc-shaped curved tube 23. The arc-shaped curved tube 23 has a U-shaped structure.

[0034] Cold water enters the first tube body 21 from the water inlet 24 and flows to the arc-shaped curved tube 23, then flows from the second end 15 to the second tube body 22, and then flows out from the water outlet 25. The cold water flows from the water inlet 24 through the gradual heating of the first tube body 21 and the second tube body 22, flows to the water outlet 25, and the temperature when flowing out is heated to the target temperature.

[0035] As a preferred implementation, the first tube body 21, the second tube body 22 and the arc-shaped curved tube are an integrated structure, which reduces the number of components, reduces costs, and improves the sealing reliability of the waterway.

[0036] Among them, the water pipe is made of heat-resistant and corrosion-resistant metal materials such as stainless steel. This overcomes the problem that the common aluminum heaters on the market directly use aluminum as water channels, which will cause aluminum to hydrolyze and corrode and fall into powder in water. The aluminum heaters on the market can only be used in some application scenarios that do not require high water quality, and cannot be used in application scenarios with drinking water and heated liquids that have a certain degree of corrosiveness, which greatly reduces its scope of application. The water pipe in this embodiment is made of stainless steel, which can completely overcome the above problems.

[0037] It should be noted that the water pipe can also be provided with a multi-layer U-shaped pipe body, such as Figure 3 The plurality of U-shaped tube bodies can be evenly distributed on the upper and lower sides of the heating tube 3.

[0038] The heat-conducting frame 1 is made of aluminum and has good thermal conductivity, and can transfer the heat of the heating pipe 3 to the water pipe 2 evenly and efficiently.

[0039] The U-shaped water heater of this embodiment is manufactured as follows. Figure 8 As shown, before manufacturing, the first tube body 21 and the second tube body 22 of the water pipe 2 are both straight strips, the heating tube 3 is also straight strips, and the heat-conducting frame 1 is a straight plate. First, the water pipe 2 and the heating tube 3 are inserted into the heat-conducting frame 1, so that the water inlet 24 and the water outlet 25 of the water pipe 2 pass through the first end 14 of the heat-conducting frame 1, and the arc-shaped curved tube 23 is located at the second end 15 of the heat-conducting frame 1, and the two ends of the heating tube 3 pass through the first end 14 and the second end 15 of the heat-conducting frame 1 respectively; then the heat-conducting frame 1 after the water pipe 2 and the heating tube 3 are installed is bent as a whole to form a U-shaped structure.

[0040] Compared with common cast aluminum heaters, the U-shaped water heater of this embodiment does not require expensive aluminum alloy die-casting molds, but only requires simple aluminum extrusion molds, thereby saving mold development costs, and the manufacturing process is simple, reducing costs.

[0041] As a preferred embodiment, the U-shaped water heater of this embodiment also includes a fixing frame 4 and a thermostat 5. The fixing frame 4 is connected to the heat-conducting frame 1 and extends to the inner side of the heat-conducting frame 1. Specifically, the fixing frame 4 includes a first connecting portion 41 and a second connecting portion 42, the first connecting portion is clamped on the heat-conducting frame 1 and fixed by bolts, and the second connecting portion 42 extends to the inner side of the heat-conducting frame 1. The thermostat 5 is fixed on the fixing frame 4 to make full use of the inner space of the heat-conducting frame 1 and reduce the occupied area. The thermostat obtains the actual heating temperature through the detection sensor and feeds it back to the controller to achieve temperature control. The fixing frame 4 is detachably connected to the heat-conducting frame 1, and defective products can be recycled and repaired, which can reduce costs.

[0042] As a preferred embodiment, the U-shaped water heater of this embodiment further includes a control board 7 and a heater body 6, the heat conducting frame 1 is installed in the heater body 6, the control board 7 is installed on one side of the heater body 6, and the thermostat 5 and the heating tube 3 are connected to the control board 7. The heater body 6 is provided with mounting holes for easy installation and fixing. The control board collects the outlet water temperature through a water temperature sensor provided at the water outlet, and compares it with the set target outlet water temperature; according to different outlet water temperatures, the output power of the heating tube is adjusted, so as to achieve the purpose of quickly reaching the target temperature and stabilizing the water temperature.

[0043] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
