Description

Technical Field

[0001] The present invention relates to the technical field of water heater processing, and particularly to a water heater, a water heater assembly method, and an auxiliary assembly tooling. Background Art

[0002] A water heater refers to a device that can heat cold water to hot water within a certain period of time through various physical principles. According to different heating principles, water heaters can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc.

[0003] As Figures 1-3 shown, the main body of a water heater in the prior art includes a housing 100', an inner tank 200', and a heat insulation layer located between the inner tank 200' and the housing 100'. The heat insulation layer is filled with polyurethane foam material. When assembling the water heater, first, a cushion layer is placed at the inner bottom of the housing 100', and then the inner tank 200' is placed inside the housing 100'. The function of the cushion layer is to adjust the relative position of the inner tank 200' and the housing 100' in the height direction so that the two water pipes 201' on the inner tank 200' are aligned with the water pipe openings 101' on the housing 100'. Then, a plastic sleeve 300' is installed. The plastic sleeve 300' includes a mating collar 301' and a limiting edge 302'. The mating collar 301' is inserted into the water pipe opening 101', and the outer wall of the mating collar 301' is in contact with the water pipe opening 101', and the inner wall of the mating collar 301' is in contact with the water pipe 201'. The limiting edge 302' abuts against the outer wall of the housing 100'. Then, the foam material is filled between the inner tank 200' and the housing 100'. After the filling process is completed, the plastic sleeve 300' can be removed. However, when using the plastic sleeve 300' for positioning, during the filling of the foam material, although the inner tank 200' does not rotate relative to the housing 100', it will move radially along the housing 100', resulting in different lengths of the parts of the water pipe 201' exposed outside the housing 100' in the finished water heater, making the appearance structure of the finished water heater inconsistent.

[0004] Therefore, it is urgent to propose a water heater to solve the above problems. Summary of the Invention

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0053] Figure 4 The structural schematic diagram of the water heater provided in this embodiment in cooperation with the auxiliary assembly tooling is shown. Figure 5 The cross - sectional schematic diagram of the water heater provided in this embodiment in cooperation with the auxiliary assembly tooling is shown. Figure 6 Shown is Figure 5Partial enlarged view at B. As Figures 4-6 shown, this embodiment provides a water heater, which includes a housing 100, an inner tank 200, and elastic cushion blocks 300. The inner tank 200 is accommodated in the housing 100. At least two water pipes 201 are provided on the inner tank 200, and through holes 101 corresponding to the water pipes 201 one by one are provided on the housing 100; the elastic cushion blocks 300 are located between the housing 100 and the inner tank 200 and sleeved on the water pipes 201. By providing the elastic cushion blocks 300 between the housing 100 and the inner tank 200, the length of the water pipes 201 extending out of the through holes 101 can be judged by the compression degree of the elastic cushion blocks 300. In the foaming material filling process of assembling the water heater, only by ensuring that the elastic cushion blocks 300 in each water heater have the same compression amount can the unity of the appearance structure of the finished water heater be ensured.

[0054] Optionally, the elastic cushion blocks 300 are made of foam material, which is convenient to obtain materials and has a low manufacturing cost. Of course, in other embodiments, the elastic cushion blocks 300 can also be made of rubber material.

[0055] In this embodiment, the elastic cushion blocks 300 are in a ring structure, and the number thereof can be one. One ring-shaped elastic cushion block 300 is simultaneously sleeved on a plurality of water pipes 201; or the number of the elastic cushion blocks 300 can be multiple, and one elastic cushion block 300 is sleeved on each water pipe 201.

[0056] In this embodiment, the number of the water pipes 201 on the inner tank 200 is two. During use, the two water pipes 201 can respectively pass through the corresponding through holes 101 on the housing 100 and then be respectively connected to an external water source and a spray assembly. That is to say, one of the two water pipes 201 on the inner tank 200 is a water inlet pipe, and the other is a water outlet pipe. Of course, in other embodiments, the number of the water pipes 201 on the inner tank 200 is not limited to two, and can also be set to three. Two of the three water pipes 201 are water outlet pipes to connect different water-using devices, and the other water pipe 201 is a water inlet pipe to connect to an external water source; the number of the water pipes 201 on the inner tank 200 can also be any number of four or more, which can be specifically adjusted according to actual needs.

[0057] This embodiment also provides a water heater assembly method for assembling the above-mentioned water heater. The water heater assembly method includes the following steps:

[0058] Sleeve the elastic cushion blocks 300 on the water pipes 201 of the inner tank 200;

[0059] Install the inner tank 200 assembled with the elastic cushion blocks 300 into the housing 100, and make the water pipes 201 on the inner tank 200 pass through the through holes 101 on the housing 100 one by one;

[0060] Pull the water pipe 201 passing through the via hole 101. When the preset pulling force is reached, fill the foaming material between the inner liner 200 and the outer shell 100.

[0061] The water heater assembly method provided in this embodiment for assembling the above water heater can determine the length of the water pipe 201 extending out of the via hole 101 according to the compression degree of the elastic cushion block 300. In the foaming material filling process of the water heater assembly, only by ensuring that the elastic cushion blocks 300 in each water heater have the same compression amount can the unity of the appearance structure of the finished water heater be ensured.

[0062] It should be noted that when pulling the water pipe 201 passing through the via hole 101, an auxiliary tool can be used in cooperation with a sensor. When the sensor detects that the pulling force reaches the preset pulling force, stop pulling, and then fill the foaming material between the inner liner 200 and the outer shell 100. During the entire process of filling the foaming material, the auxiliary tool still maintains a preset pulling force on the water pipe 201 to prevent the water pipe 201 from shifting under the action of the elastic restoring force of the elastic cushion block 300 during the foaming process.

[0063] To implement the above water heater assembly method, this embodiment also provides an auxiliary assembly tooling. The auxiliary assembly tooling includes a tooling bracket 1 and a fixing member 3. The tooling bracket 1 abuts against the outer wall of the outer shell 100 of the water heater; the fixing member 3 is rotatably arranged on the tooling bracket 1 and can correspond to and be threadedly connected with at least one water pipe 201. By rotating the fixing member 3, the corresponding water pipe 201 can be pulled. When assembling the water heater, first sleeved the elastic cushion block 300 on the water pipe 201, and then place the inner liner 200 assembled with the elastic cushion block 300 into the outer shell 100; under the action of the cushion layer in the outer shell 100, the water pipe 201 on the inner liner 200 is aligned with the corresponding via hole 101, and then the fixing member 3 is screwed onto the corresponding water pipe 201. Since the fixing member 3 is in threaded cooperation with the corresponding water pipe 201, the operator needs to screw the fixing member 3 to make the fixing member 3 fit tightly with the water pipe 201. During the process of the operator screwing the fixing member 3, it can be felt that the outer shell 100 and the inner liner 200 jointly squeeze the elastic cushion block 300. When the elastic cushion block 300 is squeezed to the preset deformation amount, the operator can stop screwing the fixing member 3. At this time, the inner liner 200 and the outer shell 100 are in place and relatively fixed. The auxiliary assembly tooling can limit the circumferential movement and radial movement of the water pipe 201 at the same time, thereby ensuring the positioning accuracy between the inner liner 200 and the outer shell 100, avoiding the movement of the water pipe 201 during the foaming process, and ensuring the unity of the appearance structure of the finished water heater. Among them, the preset deformation amount of the elastic cushion block 300 can be measured by the pulling force detected by the sensor.

[0064] It should be explained that the circumferential movement of the water pipe 201 refers to the rotation of the water pipe 201 with the axis of the inner tank 200 as the axis, and the radial movement of the water pipe 201 refers to the linear movement of the water pipe 201 along the axis direction of the through hole 101.

[0065] In one embodiment, the number of the fixing members 3 is the same as that of the water pipes 201 and they are in one-to-one correspondence, so as to further improve the positioning effect of the auxiliary assembly tool on the inner tank 200. In another embodiment, the number of the fixing members 3 can also be less than that of the water pipes 201, and the fixing members 3 are screwed on some of the water pipes 201, and this design can also achieve the above effects.

[0066] Figure 7 The structural schematic diagram of the fixing member 3 provided in this embodiment is shown. As Figure 7 and in combination with Figure 6 shown, the fixing member 3 includes a threaded sleeve 31, a connecting portion 32 and a handle portion 33. The threaded sleeve 31 is threadedly connected to the corresponding water pipe 201; a through hole 11 is provided on the tooling bracket 1, one end of the connecting portion 32 is connected to the end of the threaded sleeve 31 away from the inner tank 200, and the other end of the connecting portion 32 passes through the through hole 11 and is connected to the handle portion 33. During operation, the operator can hold the handle portion 33 to screw the threaded sleeve 31 so that it is tightened on the corresponding water pipe 201.

[0067] Of course, in other embodiments, the handle portion 33 may not be provided, and the operator can directly rotate the connecting portion 32 to screw the threaded sleeve 31.

[0068] Optionally, a limiting member 34 is provided on the connecting portion 32, and the limiting member 34 can abut against the side wall of the tooling bracket 1 away from the threaded sleeve 31. By providing the limiting member 34, the limiting member 34 and the threaded sleeve 31 can respectively abut against both sides of the tooling bracket 1, so as to ensure that the axis direction of the threaded sleeve 31 is always parallel to the thickness direction of the tooling bracket 1, so as to ensure that the operator can quickly align the threaded sleeve 31 with the water pipe 201 when installing the auxiliary assembly tool and improve the installation efficiency.

[0069] Optionally, the limiting member 34 is a limiting ring provided on the connecting portion 32, and the fitting area between the limiting ring and the tooling bracket 1 is relatively large, which can improve the limiting effect. Continuing as Figures 5-6As shown, in this embodiment, the number of water pipes 201 is two, and the number of fixing members 3 is one. The fixing member 3 is threadedly connected to one of the water pipes 201. Optionally, the auxiliary assembly tooling further includes a positioning portion 2 provided on the tooling bracket 1. The positioning portion 2 is a columnar structure and can pass through the other water pipe 201. By providing the positioning portion 2, on the one hand, the positioning portion 2 can pass through the corresponding water pipe 201 to limit the circumferential movement of the water pipe 201; on the other hand, it can also achieve rapid positioning when the auxiliary assembly tooling is assembled with the inner tank 200.

[0070] In other embodiments, positioning holes may also be provided on the positioning portion 2, and the other water pipe 201 passes through the positioning holes of the positioning portion 2, and the above effects can also be achieved.

[0071] Optionally, the positioning portion 2 and the tooling bracket 1 are of an integral structure, which can save the assembly link between the positioning portion 2 and the tooling bracket 1, improve the processing efficiency, and can also save the use of connecting parts and reduce the processing cost. Of course, in other embodiments, the positioning portion 2 and the tooling bracket 1 can also be connected by means of screws, snap connections, plug connections, welding, and gluing.

[0072] To ensure the appearance quality of the finished water heater, an anti-abrasion member 4 is also provided between the tooling bracket 1 and the outer shell 100 to prevent the tooling bracket 1 from being frequently abraded by friction with the outer wall of the outer shell 100 when the operator screws the fixing member 3. Optionally, the anti-abrasion member 4 is made of rubber material, which has a good anti-abrasion effect, is convenient for obtaining materials, and can also reduce the manufacturing cost.

[0073] Note that the above is only the preferred embodiment of the present invention and the applied technical principle. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, it can also include more other equivalent embodiments, and the scope of the present invention is determined by the scope of the appended claims.
