[0033] Aiming at the problems of complicated processing technology and high production cost of double-tank water heaters in related technologies, the utility model provides a water heater tank.

[0034] The following combination Figures 2 to 8 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, on the one hand, Figure 2 and Figure 4 As shown, a water heater inner tank is provided, comprising: a first inner tank 1 and a second inner tank 2.

[0036] Specifically, the first inner liner 1 is provided with an incision 101 extending along its length direction, and the second inner liner 2 is partially inserted into the incision 101 and welded to the incision 101; wherein, the part of the second inner liner 2 inserted into the incision 101 is also provided with a connecting port 201, and the second inner liner 2 is connected with the first inner liner 1 through the connecting port 201.

[0037] Compared to using an inner liner with a "D"-shaped cross-section, this embodiment forms a notch 101 by cutting the first inner liner 1 after molding, which can retain the original stamping process of the first inner liner 1 and the second inner liner 2, avoid complicated adjustments to the stamping process, and thus effectively reduce the initial cost investment of the water heater inner liner. Secondly, during the assembly process, using the notch 101, the operator can complete the installation and positioning of the first inner liner 1 and the second inner liner 2 in a short time, which helps to simplify the assembly difficulty and ensure the reliability of the welding at the subsequent connection.

[0038] It is understandable that if Figure 2 and Figure 4 As shown, the length of the cutout 101 coincides with the length of the first inner liner 1. This solution significantly increases the contact area between the first and second inner liner 1, 2, expands the weld area between the first and second inner liner 1, 2, and improves the connection strength between the first and second inner liner 1, 2. Furthermore, because this solution increases the weld area between the first and second inner liner 1, 2, when external forces are applied to the weld between the first and second inner liner 1, 2, the forces are evenly distributed across the weld area, avoiding localized stress concentration at the weld between the first and second inner liner 1, 2.

[0039] It should be noted that the length direction of the incision 101 is Figure 2 and Figure 3 The direction shown in is consistent.

[0040] It should be noted that to ensure the sealing of the joint between the first inner liner 1 and the second inner liner 2, a circumferential welding process can be performed on the joint to enhance the sealing effect of the water heater inner liner and prevent water leakage. After welding is completed, a continuous weld seam will be formed at the joint, and the connection strength of the first inner liner 1 and the second inner liner 2 can be enhanced, thereby effectively reducing the possibility of deformation due to heat at this location and improving the reliability and safety of the water heater inner liner.

[0041] In one embodiment, Figure 2 and Figure 3 As shown, the orthographic projection of the communication port 201 toward the incision 101 is located within the range of the incision 101. This arrangement can prevent the communication port 201 from being misaligned during assembly and avoid leakage problems at the connection between the first inner liner 1 and the second inner liner 2.

[0042] In one embodiment, Figures 4 to 7 As shown, the first inner liner 1 and the second inner liner 2 are arranged side by side, wherein the first inner liner 1 and the second inner liner 2 can be arranged side by side up and down, or side by side left and right, and the specific selection can be made according to actual needs, as long as it is convenient to weld the first inner liner 1 and the second inner liner 2. For example, the first inner liner 1 is located above the second inner liner 2 and is arranged side by side with the second inner liner 2. The axial direction of the communication port 201 is consistent with the gravity direction of the water in the water heater inner liner. When the water in the water heater inner liner is heated, the water in the first inner liner 1 and the second inner liner 2 can fully undergo convective heat exchange, thereby effectively shortening the heating time and improving the heating efficiency.

[0043] In a specific embodiment, Figure 2 and Figure 3 As shown, the first inner liner 1 and the second inner liner 2 both include a cylindrical section 102 and an arcuate section 103 located at both ends of the cylindrical section 102, and the incision 101 is located in the cylindrical section 102 and extends to the arcuate section 103 at both ends. Among them, the first inner liner 1 is provided with an incision 101, and a portion of the second inner liner 2 is inserted into the incision 101 and a connecting port 201 is provided on the portion. It can be understood that compared to the inner liner with a "D"-shaped cross-sectional shape. The arcuate surfaces of the first inner liner 1 and the second inner liner 2 in this embodiment can better disperse the stress acting on their surfaces and extend the service life of the water heater inner liner. In addition, since the side walls of the first inner liner 1 and the second inner liner 2 are both arcuate surfaces, a relatively sufficient operating space can be reserved at the connection between the two, thereby ensuring the welding quality of the connection between the first inner liner 1 and the second inner liner 2.

[0044] Furthermore, to ensure sufficient contact area between the first inner liner 1 and the second inner liner 2 while preventing the second inner liner 2 from excessively occupying the water storage space of the first inner liner 1, the size of the cutout 101 needs to be set within an appropriate range. Specifically, the cutout 101 forms a fan-shaped angle with the axis of the first inner liner 1, and the angle of the fan-shaped angle is 30 degrees to 120 degrees. Preferably, the angle between the cutout 101 and the axis of the first inner liner 1 is 45 degrees.

[0045] In addition, if Figure 2 and Figure 3 As shown, to facilitate installation of necessary equipment, such as heating pipes, into the first and second inner containers 1, 2, mounting openings 1031 communicating with the interiors of the first and second inner containers 1, 2 can be provided on the curved surface segments 103, respectively. Furthermore, to reduce the difficulty of assembling the first and second inner containers 1, 2 with other components of the water heater and improve assembly convenience, flanges 7 can be provided on the first and second inner containers 1, 2, and fitted over the corresponding mounting openings 1031.

[0046] In one embodiment, Figure 3 As shown, there are multiple connecting ports 201, and the multiple connecting ports 201 are spaced apart along the length direction of the second inner liner 2. A drain port 203 is also provided on the side of the second inner liner 2 away from the first inner liner 1. The drain port 203 is coaxially arranged with one of the connecting ports 201 and is connected through a water supply pipeline. By providing multiple connecting ports 201, on the one hand, the internal pressure distribution of the first inner liner 1 and the second inner liner 2 can be made more uniform; on the other hand, when heating, the multiple connecting ports 201 can increase the heat exchange area of the water flow inside the first inner liner 1 and the second inner liner 2, thereby improving the heat exchange effect. Secondly, the drain port 203 is provided on the inner liner provided with the connecting port 201, and the axial direction of the drain port 203 is consistent with the axial direction of one of the connecting ports 201, which helps to ensure the coaxiality of the two during the production process, reduce manufacturing errors, and improve the convenience and accuracy when assembling the water supply pipeline.

[0047] In order to improve the convenience of drainage, Figure 2 and Figure 3 As shown, in a specific embodiment, the drain outlet 203 is formed with a water outlet pipe 2031 .

[0048] It is understandable that as the user uses the water, the water level in the water heater tank will gradually decrease. Figure 2 and Figure 3 As shown, to ensure that the water heater tank can continuously provide hot water to the user, a water inlet pipe 204 can be provided on one of the first inner tank 1 and the second inner tank 2 to maintain the water level within a reasonable range. In addition, as the water heater tank is used, some impurities will gradually accumulate inside it. To facilitate the timely removal of impurities in the water heater tank, a sewage pipe 202 can also be provided on one of the first inner tank 1 and the second inner tank 2 to communicate with it.

[0049] In one embodiment, Figure 6 and Figure 8 As shown, the container further includes a panel 3, which is disposed around the welded portion between the first inner liner 1 and the second inner liner 2 and is welded to the sidewalls of the first inner liner 1 and the second inner liner 2. The addition of the panel 3 can provide additional support for the connection between the first inner liner 1 and the second inner liner 2 and significantly enhance the structural strength of the welded portion.

[0050] In one embodiment, Figure 7As shown, the enclosure 3 and the side walls of the first inner liner 1 and the second inner liner 2 together form a closed space for accommodating the phase change energy storage material. It can be understood that the phase change energy storage material is a material that can store or release heat. Therefore, after the phase change energy storage material is filled in the closed space formed by the enclosure 3 and the side walls of the first inner liner 1 and the second inner liner 2, the phase change energy storage material can automatically release or store heat according to the changes in the water temperature of the first inner liner 1 and the second inner liner 2. In this way, the heat preservation time of the water heater inner liner can be effectively extended and the energy efficiency coefficient of the water heater can be reduced.

[0051] In one embodiment, Figure 8 As shown, the enclosure 3 is provided with a connecting pipe 301 connected to the enclosed space, and a sealing cover 5 is provided at the end of the connecting pipe 301 away from the enclosure 3, and a sealing ring 4 is also provided between the sealing cover 5 and the connecting pipe 301. By providing the connecting pipe 301, it is convenient to perform subsequent maintenance and replacement of the phase change energy storage material in the enclosed space. Secondly, by providing the sealing ring 4 and the sealing cover 5 on the connecting pipe 301, the sealing of the enclosed space can be ensured, and the phase change energy storage material can be protected from the influence of the external environment. Furthermore, in order to improve the convenience of installing and removing the sealing cover 5, a threaded structure that cooperates with each other can be provided on the sealing cover 5 and the connecting pipe 301.

[0052] In one embodiment, Figure 4 and Figure 6 As shown, the structure further includes a hanger 6, the ends of which are welded to the outer walls of the first inner liner 1 and the second inner liner 2, respectively. The hanger 6 is also provided with mounting holes. This arrangement not only enhances the overall structural stability of the first inner liner 1 and the second inner liner 2, but also makes it easier to assemble the water heater inner liner with other components, thereby improving the convenience of overall assembly.

[0053] According to another embodiment of the present invention, a water heater is provided, comprising: a housing and the aforementioned water heater inner tank, the water heater inner tank being mounted within the housing. Compared to a water heater mounted with an inner tank having a D-shaped cross-section, a water heater mounted with the aforementioned inner tank has a lower processing complexity and lower initial production costs. Furthermore, the water heater of the present invention has other advantages of the aforementioned inner tank, which will not be elaborated upon here.

[0054] It should be noted that the water heater in this embodiment can be an electric water heater or a gas water heater.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
