Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to an electric water heater. Background Art

[0002] An electric water heater is a water heater that uses electricity as an energy source for heating. It includes an outer shell and an inner tank assembly. The inner tank assembly is installed in the outer shell. The inner tank assembly includes an inner tank and an inlet and outlet water pipe. The inlet and outlet water pipes pass through the inner tank and through the outer shell to connect to an external cold water pipe and a hot water pipe. At present, in order to keep the hot water in the electric water heater warm, the gap between the outer shell and the inner tank is filled with a foaming material to form an insulation layer through a foaming process to keep the hot water in the inner tank warm.

[0003] However, the inlet and outlet pipes of the existing electric water heater pass through the inner tank and are fixed on the outer wall of the inner tank, and then pass through the through hole of the outer shell to connect the external cold water pipe and hot water pipe. That is, the inlet and outlet pipes are fixedly connected to the inner tank, and during the foaming process, the expansion of the foaming material causes the inner tank to shift, thereby driving the inlet and outlet pipes to shift, so that the pipe openings of the inlet and outlet pipes do not correspond to the positions of the through holes of the outer shell, and the external cold water pipe and hot water pipe cannot be accurately connected.

[0004] Although the prior art allows the tooling to pass through from the outside to locate the pipe openings of the inlet and outlet pipes, there is a gap when the tooling is installed. Therefore, the tooling cannot firmly fix the pipe openings of the inlet and outlet pipes during the foaming process, making it difficult to overcome the problem of displacement of the pipe openings of the inlet and outlet pipes. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention.

[0034] See also Figure 1 and Figure 2 The utility model provides an electric water heater, which includes a shell 1 and an inner tank assembly 2. The shell 1 is provided with an installation cavity 11, and the side wall of the shell 1 is provided with a first installation hole and a second installation hole. The inner tank assembly 2 is installed in the installation cavity 11, and the inner tank assembly 2 includes an inner tank 21, a water inlet pipe 22 and a water outlet pipe 23. A gap is set between the inner tank 21 and the cavity wall of the installation cavity 11. The water inlet pipe 22 and the water outlet pipe 23 are both arranged outside the inner tank 21, and the water outlet end of the water inlet pipe 22 and the water inlet end of the water outlet pipe 23 both extend into the inner tank 21.

[0035] Specifically, the shell 1 is hollow inside to form a mounting cavity 11 , and an opening 12 is provided at one end of the shell 1 in the length direction. The opening 12 is connected to the mounting cavity 11 , so that the liner assembly 2 can be placed in the mounting cavity 11 through the opening 12 .

[0036] The inner tank assembly 2 includes an inner tank 21, an inlet pipe 22 and an outlet pipe 23. The inner tank 21 has an inner tank cavity. An installation opening is provided at one end of the inner tank 21 in the longitudinal direction, and the installation opening is communicated with the inner tank cavity. A flange 24 is sealed and installed at the installation opening. The inlet pipe 22 and the outlet pipe 23 are both located in the installation cavity 11 outside the inner tank 21, and the outlet end of the inlet pipe 22 and the inlet end of the outlet pipe 23 are both sealed and pass through the flange 24 and extend to the inner tank cavity.

[0037] In the present invention, there may be only one inner liner 21, or there may be two or more inner liner 21. Figure 2Taking two inner tanks 21 as an example, the two inner tanks 21 are arranged side by side and closely, and are arranged along the length direction, and the corresponding ends of the two inner tanks 21 in the length direction are arranged flush to ensure that the two inner tanks 21 are stably assembled in the installation cavity 11. The water inlet pipe 22 and the water outlet pipe 23 can be connected in parallel with the two inner tanks 21, that is, the water inlet pipe 22 and the water outlet pipe 23 are split into two branches at the two inner tanks 21, wherein the water inlet end of the first branch water inlet pipe extends to the first inner tank cavity, the water outlet end of the first branch water outlet pipe extends to the first inner tank cavity, the water inlet end of the second branch water inlet pipe extends to the second inner tank cavity, and the water outlet end of the second branch water outlet pipe extends to the second inner tank cavity. In this way, hot water can be provided to the outside through the two inner tanks 21 at the same time, and the amount of hot water is sufficient. Alternatively, the water inlet pipe 22 and the water outlet pipe 23 can also be connected in series with the two inner tanks 21, that is, the water inlet end of the water inlet pipe 22 extends into the first inner tank cavity, and the water outlet end of the water outlet pipe 23 extends into the second inner tank cavity, and the first inner tank cavity and the second inner tank cavity are connected by a connecting pipe. In this way, the cold water is first preliminarily heated in the first inner tank cavity, and then enters the second inner tank cavity through the connecting pipe for heating, and then hot water is provided from the second inner tank cavity to the outside, so as to ensure the output temperature of the hot water and improve the hot water output rate.

[0038] Regardless of whether the number of the inner tank 21 is one or two or more, the water inlet end of the water inlet pipe 22 needs to be connected to the external cold water pipe to input cold water into the inner tank cavity, and the water outlet end of the water outlet pipe 23 needs to be connected to the external hot water pipe to output hot water to the outside. In the electric water heater of the prior art, the water inlet pipe is fixed to the outer wall of the inner tank, and its water inlet end directly passes through the first mounting hole to connect to the external cold water pipe, and the water outlet pipe is fixed to the outer wall of the inner tank, and its water outlet end directly passes through the second mounting hole to connect to the external hot water pipe. However, since the gap between the outer shell and the inner tank is filled with foaming material, the hot water in the inner tank is insulated by forming an insulation layer through a foaming process. When the foaming process is performed, the expansion of the foaming material causes the inner tank to shift, thereby driving the water inlet pipe and the water outlet pipe to shift, so that the water inlet end of the water inlet pipe is displaced compared to the first mounting hole, and the water outlet end of the water outlet pipe is displaced compared to the second mounting hole. Although the water inlet end of the water inlet pipe can be fixed from the outside through the first mounting hole by means of a tool, and the water outlet end of the water outlet pipe can be fixed through the second mounting hole, however, since there is a gap between the tool and the first mounting hole and the second mounting hole, the water inlet end of the water inlet pipe and the water outlet end of the water outlet pipe are not firmly fixed, and it is difficult to avoid the displacement of the water inlet end of the water inlet pipe and the water outlet end of the water outlet pipe, resulting in positional offset when the water inlet end of the water inlet pipe and the water outlet end of the water outlet pipe are fixed.

[0039] To resolve this issue, see Figure 2 and Figure 3The electric water heater of the utility model further comprises a connection assembly 3, which is an integrated structure, is arranged in the mounting cavity 11, and is fixedly connected to both the inner tank 21 and the outer shell 1. The connection assembly 3 comprises a water inlet connection portion 31 adapted to the first mounting hole and a water outlet connection portion 32 adapted to the second mounting hole, the water inlet connection portion 31 is connected to the water inlet end of the water inlet pipe 22 and seals through the first mounting hole, and the water outlet connection portion 32 is connected to the water outlet end of the water outlet pipe 23 and seals through the second mounting hole.

[0040] The connection component 3 is fixedly mounted on the outer wall of the inner tank 21, and the connection component 3 is fixedly mounted with the outer shell 1. The connection component 3 is an integrated structure with good firmness. The inner tank 21 and the outer shell 1 are fixedly connected by the connection component 3, thereby avoiding displacement of the inner tank relative to the outer shell during the foaming process, so that the water inlet pipe 22 and the water outlet pipe 23 will not be relatively displaced compared with the inner tank 21 and the outer shell 1, thereby ensuring the relative fixation between the inner tank component 2 and the outer shell 1. In addition, the connection component 3 is provided with a water inlet connection portion 31 and a water outlet connection portion 32, and the water inlet connection portion 31 and the water outlet connection portion 32 can quickly and stably connect the water inlet pipe 22 and the water outlet pipe 23 in the installation cavity 11, without the need to use a limit fixture, thereby improving the assembly efficiency of the electric water heater.

[0041] In the present invention, the water inlet pipe 22 and the water outlet pipe 23 are both bent in an arc shape and arranged outside the inner tank 21. When the water inlet end of the water inlet pipe 22 does not match the position of the water inlet connection portion 31 due to production tolerance, and / or the water outlet end of the water outlet pipe 23 does not match the position of the water outlet connection portion 32, the position of the water inlet end of the water inlet pipe 22 and / or the water outlet end of the water outlet pipe 23 can be adjusted by pulling the arc-shaped bent portion to match and install.

[0042] See also Figure 2 The inner liner assembly 2 further includes a fixing member 4, which is fixed to the outer wall of the inner liner 21, and the connecting assembly 3 is fixedly connected to the fixing member 4. Compared with the connecting assembly 3 being directly fixed to the outer wall of the inner liner 21, by setting the fixing member 4, the installation process of fixing the connecting assembly 3 to the fixing member 4 is simpler and more convenient to install. Moreover, when there are two or more inner liners 21, the setting of the fixing member 4 can fix the two or more inner liners 21 to prevent relative displacement.

[0043] The fixing member 4 includes a first fixing ring 41, a second fixing ring 42 and a connecting member 43. The first fixing ring 41 and the second fixing ring 42 are sleeved on the outer wall of the inner liner 21, and the first fixing ring 41 and the second fixing ring 42 are spaced apart along the length direction of the inner liner 21. The first fixing ring 41 and the second fixing ring 42 are connected by the connecting member 43, and the connecting assembly 3 is fixedly mounted on the connecting member 43. When there are two or more inner liners 21, the first fixing ring 41 and the second fixing ring 42 can fix the two or more inner liners 21 together to prevent relative displacement. It should be noted that the first fixing ring 41 and the second fixing ring 42 are sleeved outside the two or more inner liners 21, and the first fixing ring 41 and the second fixing ring 42 should be adapted to the size of the outer wall of the two or more inner liners 21 assembly at the corresponding position to ensure that the first fixing ring 41 and the second fixing ring 42 firmly fix the two or more inner liners 21.

[0044] On the basis that the first fixing ring 41 and the second fixing ring 42 cooperate to fix two or more inner liner 21, the connecting member 43 connects the first fixing ring 41 and the second fixing ring 42 to ensure that there is no relative displacement between the first fixing ring 41 and the second fixing ring 42. In addition, the connecting assembly 3 is fixedly mounted on the connecting member 3, and the inner liner 21 and the connecting assembly 3 can be relatively fixed by the fixing member 4.

[0045] In the present invention, the distance between the first fixing ring 41 and the corresponding end of the inner liner 21 is equal to the distance between the second fixing ring 42 and the corresponding end of the inner liner 21. Thus, the fixing member 4 can be evenly fixed on the outer wall of the inner liner 21, so that the fixing member 4 can be more stably connected to the inner liner 21.

[0046] Furthermore, the first fixing ring 41, the second fixing ring 42 and the connecting member 43 of the present invention are connected as an integral structure, which improves the firmness of the fixing member 4 and makes the connection between the fixing member 4 and the inner liner 21 and the connecting assembly 3 more stable.

[0047] On the basis of the above structure, the connection assembly 3 further includes a connection plate 33, the water inlet connection portion 31 and the water outlet connection portion 32 are arranged on the connection plate 33, and the connection plate 33 is fixedly connected to the housing 1 and the connection member 43. The cross-sectional area of ​​the connection plate 33 is large, thereby increasing the contact area between the connection assembly 3, the connection member 43 and the housing 1, making the connection between the connection assembly 3, the connection member 43 and the housing 1 more firmly.

[0048] When the connecting plate 33 is fixed to the connecting member 43, the distance between the first fixing ring 41 and the corresponding end of the connecting plate 33 is equal to the distance between the second fixing ring 42 and the corresponding end of the connecting plate 33. Figure 2For example, the distance between the right end of the first fixing ring 41 and the left end of the connecting plate 33 is equal to the distance between the left end of the second fixing ring 42 and the right end of the connecting plate 33, that is, the connecting plate 33 is installed in the middle area of ​​the connecting member 43, so that the connecting member 43 is evenly stressed, thereby improving the stability of the installation.

[0049] The water inlet connection part 31 and the water outlet connection part 32 are arranged on the connection plate 33. Specifically, the water inlet connection part 31 includes a water inlet interface 311 and a first rib 312. The water inlet interface 311 is connected to the water inlet end of the water inlet pipe 22 and passes through the first mounting hole. The first rib 312 is an annular structure and surrounds the water inlet interface 311. The first rib 312 is adapted to the first mounting hole so that the first rib 312 passes through the first mounting hole in a sealed manner. The water inlet interface 311 is installed on the connection plate 33. One end of the water inlet interface 311 faces the outer shell 1 to pass through the first mounting hole, and the other end of the water inlet interface 311 faces the inner liner 21 to connect the water inlet end of the water inlet pipe 22. The first rib 312 is installed on the end surface of the connection plate 33 facing the outer shell 1. The first rib 312 protrudes from the connection plate 33 so that the first rib 312 can pass through the first mounting hole, and the first rib 312 is sealed and connected to the hole wall of the first mounting hole to prevent water leakage. The first rib 312 has a positioning function so that the housing 1 and the connecting component 3 can be accurately installed.

[0050] The water outlet connection part 32 includes a water outlet interface 321 and a second rib 322. The water outlet interface 321 is connected to the water outlet end of the water outlet pipe 23 and passes through the second mounting hole. The second rib 322 is a ring structure and surrounds the water outlet interface 321. The second rib 322 is adapted to the second mounting hole so that the second rib 322 passes through the second mounting hole in a sealed manner. The water outlet interface 321 is installed on the connecting plate 33. One end of the water outlet interface 321 faces the outer shell 1 to pass through the second mounting hole, and the other end of the water outlet interface 321 faces the inner tank 21 to connect the water outlet end of the water outlet pipe 23. The second rib 322 is installed on the end surface of the connecting plate 33 facing the outer shell 1. The second rib 322 protrudes from the connecting plate 33 so that the second rib 322 can pass through the second mounting hole, and the second rib 322 is sealed and connected to the hole wall of the second mounting hole to avoid water leakage. The second rib 322 has a positioning function so that the outer shell 1 and the connecting component 3 can be accurately installed.

[0051] The water inlet connection part 31, the water outlet connection part 32 and the connecting plate 33 are connected as an integral structure, which ensures the stability of the connection between the components in the connecting component 3. When the connecting component 3 is fixedly connected to the outer shell 1 and the inner tank 21, the relative fixation between the three can be ensured.

[0052] Furthermore, the water inlet interface 311 passes through the connecting plate 33, and one end of the water inlet interface 311 facing away from the first rib 312 bends and extends toward the width edge of the connecting plate 33 and is connected to the water inlet end of the water inlet pipe 22. The water outlet interface 321 passes through the connecting plate 33, and one end of the water outlet interface 321 facing away from the second rib 322 bends and extends toward the width edge of the connecting plate 33 and is connected to the water outlet end of the water outlet pipe 23. Thus, the connection between the water inlet end of the water inlet pipe 22 and the water inlet interface 311 is located at the side of the connecting plate 33, and the connection between the water outlet end of the water outlet pipe 23 and the water outlet interface 321 is located at the side of the connecting plate 33. Compared with connecting on the side of the connecting plate 33 facing away from the housing 1, the structural design of the utility model is more convenient for assembly and connection.

[0053] On this basis, the connector 43 includes a mounting portion and an avoidance portion, the mounting portion is respectively located at both ends of the avoidance portion in the length direction, and the distance between the mounting portion and the outer wall of the inner liner 21 is greater than the distance between the avoidance portion and the outer wall of the inner liner 21, so that the connector 43 is a "concave"-shaped structure, the avoidance portion is arranged corresponding to the water inlet interface 311 and the water outlet interface 312, and the connecting plate 33 is fixedly connected to the mounting portion. The arrangement of the avoidance portion facilitates the installation of the water inlet interface 311 and the water outlet interface 321, so that the water inlet interface 311 is connected to the water inlet end of the water inlet pipe 22 at the side of the connecting plate 33, and the water outlet interface 321 is connected to the water outlet end of the water outlet pipe 23 at the side of the connecting plate 33.

[0054] For the fixed connection of the present invention, the inner liner 21 and the fixing member 4, the fixing member 4 and the connecting component 3, and the connecting component 3 and the outer shell 1 are all fixedly connected by screws.

[0055] Specifically, the first fixing ring 41 and the second fixing ring 42 are both fixedly connected to the outer wall of the inner liner 21 by screws. The two ends of the connecting plate 33 in the length direction are provided with first screw holes 34, so that the connecting plate 33 is fixedly connected to the mounting portion of the connecting member 43 by screws passing through the first screw holes 34. A plurality of second screw holes 35 are distributed around the first convex rib 312 and the second convex rib 322 of the connecting plate 33, so that the connecting plate 33 is fixedly connected to the outer shell 1 by screws passing through the second screw holes 35. In this way, the connecting component 3 of the utility model can be made of metal material or plastic material, and the material requirements of the connecting component 3 are relatively low.

[0056] Of course, in practical applications, the fixed connection method can also be welding, riveting, gluing and other connection methods. Different connection methods have different requirements on the material of the components, which will not be elaborated here.

[0057] It should be noted that the “length direction” mentioned in the present invention is based on the longer side of the component, and similarly, the “width direction” is defined based on the wide side of the component.

[0058] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
