Description

Technical Field

[0001] The present application relates to the technical field of water heaters, and in particular to a reinforcement component, a water tank and a water heater. Background Art

[0002] As a water storage device, water tanks can be seen everywhere in daily life. According to the pressure-bearing mode, they can be divided into closed and open types. Because closed water tanks need to work under pressure, they are generally ball-end cylindrical structures, which require thicker materials and higher manufacturing process requirements. Open water tanks are connected to the atmosphere and work under normal pressure, so the requirements for the production of their inner tanks are lower, and the structure is relatively simple, and they can be made into different shapes. However, as the capacity of the water tank increases, the pressure of the internal liquid on the water tank wall will also increase. At this time, if the strength of the water tank is not enough, it will bulge and deform. At present, the most common way to avoid the bulging of the side wall of the water tank is to increase the thickness of the water tank material or add reinforcing ribs to the water tank to increase the strength. However, increasing the thickness of the material not only causes unnecessary waste of materials, but also increases production costs. Although the use of reinforcing ribs has a certain effect, when the length of the water tank is long, the center of the water tank is still prone to bulging and deformation. Utility Model Content

[0005] In a possible implementation, the slide rail is provided with a slide groove along its extension direction, and both ends of the pull plate are respectively provided with sliding parts that slide with the slide groove. When the sliding part of the pull plate is located in the slide groove, the two slide rails can be constrained along the width direction of the box.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] In order to solve the problems in the prior art, the present application provides a reinforcement component, a water tank and a water heater. The reinforcement component can effectively improve the strength of the water tank and prevent the water tank from swelling and deforming due to high internal pressure.

[0034] like Figure 1-6 As shown, an embodiment of the present application provides a reinforcement component, which is arranged in a box body 3 of a water tank; the reinforcement component includes two slide rails 1 and a pull plate 2.

[0035] The two slide rails 1 are respectively arranged on the inner sides of the side walls of the box body 3 extending along the length direction, and the two slide rails 1 are arranged opposite to each other.

[0036] The two ends of the pull plate 2 are respectively slidably matched with the two slide rails 1 , and the two side walls of the box body 3 extending along the length direction are connected through the two slide rails 1 and the pull plate 2 .

[0037] In the present application, the two ends of the pull plate 2 are slidably inserted into the two opposite slide rails 1, so that the two side walls extending in the extension direction of the box body 3 are connected, which can effectively improve the strength of the water tank and avoid the water tank from swelling and deforming due to the high internal pressure. By arranging the reinforcement component in the box body 3, the material thickness of the box body 3 can be made thinner while ensuring the strength, thereby saving costs. The thinning of the material is also conducive to the processing and forming of the plate.

[0038] In the related art, the open water tank of the existing water heater is generally processed into a cuboid to reduce the occupied space because the inside is not under pressure. However, as the capacity of the water tank increases, the water pressure inside the water tank increases, which makes the side wall of the water tank along the length direction prone to bulging and deformation. The current solution is to set reinforcing ribs on the side wall of the water tank. Although it can increase the strength of the water tank to a certain extent, when the length of the water tank along the length direction is long, bulging will still occur in the middle of the water tank. There are also some connecting plates welded inside the water tank, which connect the two side walls of the water tank extending along the length direction through the connecting plates, but it is not applicable to the water tank of the water heater, because the water tank of the water heater also has heat exchange tubes 4, heaters 5, thermocouples, water supply pipes, etc. when assembling, and the heat exchange tubes 4 and heaters 5 are generally arranged horizontally, so welding the connecting plates inside the water tank will affect the assembly of the water tank of the water heater.

[0039] In the present application, the slide rail 1 is pre-welded on the inner wall of the box body 3, and after the heat exchange tube 4, the heater 5 and other components are assembled, the two ends of the pull plate 2 are slid into the slide rail 1, and the pull plate 2 connects the two side walls of the box body 3, thereby constraining the two side walls extending in the length direction of the box body 3 to be away from each other, thereby preventing the middle part of the box body 3 from bulging and deforming. Moreover, it will not affect the assembly of the internal components of the box body 3.

[0040] Specifically, in order to reduce the occupied space, the open water tank generally adopts a thin rectangular parallelepiped structure. The length of the box body 3 is generally much greater than the width. When the internal capacity of the box body 3 is large, the side wall with a larger surface area, that is, the side wall extending along the length direction of the box body 3, will first swell. Therefore, the reinforcement component is arranged between the two side walls extending along the length direction. Of course, if the length and width of the box body 3 are equal, the four inner side walls of the box body 3 can also be provided with slide rails 1, and then the four side walls of the box body 3 can be restrained by the cross-shaped pull plate 2.

[0041] like Figure 3-6 As shown, in some embodiments, the slide rail 1 is provided with a slide groove 11 along its own extension direction, and the two ends of the pull plate 2 are respectively provided with sliding parts 21 that slide with the slide groove 11. When the sliding part 21 of the pull plate 2 is located in the slide groove 11, the two slide rails 1 can be constrained along the width direction of the box body 3.

[0042] Specifically, the slide groove 11 on the slide rail 1 has an opening at the end, and the sliding portion 21 of the pull plate 2 slides into the slide groove 11 through the opening, thereby realizing the sliding fit between the pull plate 2 and the slide rail 1. When the pull plate 2 and the slide rail 1 are slidably matched, the two slide rails 1 can be constrained in the width direction, and the two slide rails 1 are fixedly arranged on the inner wall of the box body 3, thereby constraining the two side walls of the box body 3 extending in the length direction, and preventing the two side walls of the box body 3 extending in the length direction from bulging and deformation.

[0043] In some embodiments, the length of the sliding portion 21 is equal to the length of the pulling plate 2 .

[0044] In the present application, the sliding portion 21 is arranged at the end of the pull plate 2 and along the entire edge of the pull plate 2, so that when the sliding portion 21 fully slides into the slide groove 11, the entire sliding portion 21 and the slide groove 11 can both play the role of connecting the two side walls, thereby further ensuring the connection effect of the two side walls extending along the length direction of the box body 3, so that the two side walls are constrained within the entire range of the slide rail 1.

[0045] In some embodiments, the box body 3 includes a bottom cover 31 and a barrel body 32 disposed on the bottom cover 31 , and the slide rail 1 extends along the height direction of the barrel body 32 .

[0046] In the present application, the barrel body 32 is a cylindrical structure with openings at the top and bottom. The cross-sectional area of ​​the barrel body 32 is rectangular. The barrel body 32 is welded to the bottom cover 31 at the bottom. By extending the slide rail 1 along the height direction of the barrel body 32, it is convenient to slide and insert the pull plate 2 and the slide rail 1 during assembly, thereby improving the convenience of assembly. Moreover, the sliding cooperation between the pull plate 2 and the slide rail 1 can also play a positioning effect when assembling the barrel body 32 and the bottom cover 31, thereby ensuring the assembly accuracy between the barrel body 32 and the bottom cover 31.

[0047] In some embodiments, the bottom of the pulling plate 2 is connected to the bottom cover 31 .

[0048] Specifically, the bottom of the pull plate 2 and the bottom cover 31 can be fixed by welding or by screws. Preferably, the pull plate 2 and the bottom cover 31 are fixed by welding, so that it is possible to avoid setting a through hole on the bottom cover 31, so that the pull plate 2 is located in the box body 3, and the sealing of the bottom of the box body 3 can be ensured.

[0049] In the present application, by fixing the bottom of the pull plate 2 to the bottom cover 31 instead of separately arranging the pull plate 2 and the bottom cover 31, it is possible to prevent the pull plate 2 from shaking in the slide groove 11 and generating noise; and when components extending along the length direction are installed on the bottom cover 31, such as the heat exchange tube 4, the heater 5, etc., they need to pass through the pull plate 2. If the position of the pull plate 2 and the bottom cover 31 is not fixed, swinging will occur, which is not convenient for the installation and fixation of components such as the heat exchange tube 4 and the heater 5.

[0050] In the actual assembly process, the pull plate 2 is first welded to the bottom cover 31, and then the heat exchange tube 4, heater 5 and other components that need to pass through the pull plate 2 are installed on the bottom cover 31. After the entire bottom cover 31 is assembled, the barrel body 32 is aligned with the bottom cover 31 and the barrel body 32 is moved from top to bottom so that the slide rail 1 in the barrel body 32 can be slidably connected with the sliding part 21 of the pull plate 2, and finally the barrel body 32 and the bottom cover 31 are welded and fixed.

[0051] Specifically, the box body 3 further includes a top cover 33 disposed on the top of the barrel body 32. The top cover 33 and the barrel body 32 are also welded and fixed. After all the assemblies inside the box body 3 are completed, the top cover 33 is installed.

[0052] In some embodiments, a connecting portion 22 parallel to the bottom cover 31 is disposed at the bottom of the pull plate 2 , and the connecting portion 22 is connected to the bottom cover 31 .

[0053] like Figure 2-3 As shown, in the present application, a connecting portion 22 is provided at the bottom of the pull plate 2, and the connecting portion 22 is parallel to the bottom cover 31, thereby increasing the connection area between the pull plate 2 and the bottom cover 31, and can ensure the fixing effect of the pull plate 2 and the bottom cover 31, thereby ensuring the accuracy of the position of the pull plate 2, that is, the pull plate 2 and the bottom cover 31 can be kept vertical, and the slide rail 1 also keeps vertical to the bottom cover 31, thereby facilitating the plug-in matching of the pull plate 2 and the slide rail 1.

[0054] In some embodiments, the height a of the pull plate 2 satisfies the following relationship: 0.5*b≤a≤b, where b is the height of the barrel body 32 .

[0055] In the present application, since the part of the box body 3 that is most prone to bulging is the middle part of the side wall extending along the length direction of the box body 3, the bottom of the pull plate 2 is connected to the bottom cover 31. By setting the length of the pull plate 2 to be greater than half the height of the barrel body 32, bulging of the middle part of the box body 3 can be effectively avoided.

[0056] Preferably, the height of the pull plate 2 is equal to two-thirds of the height of the barrel body 32 , which can not only ensure that the central part of the box body 3 will not bulge, but also effectively reduce the height of the pull plate 2 and reduce the consumables of the pull plate 2 .

[0057] like Figure 2-3 As shown, in some embodiments, the pull plate 2 is provided with an avoidance hole 23 for avoiding components in the box body 3 .

[0058] In the present application, a variety of components are arranged in the water tank of the water heater, such as a heat exchange tube 4, a heater 5, etc. These components are arranged horizontally and need to pass through the pull plate 2. Therefore, an avoidance hole 23 is arranged on the pull plate 2 to avoid these components in the box body 3. Moreover, the avoidance hole 23 will not occupy the edge position of the pull plate 2, and can also ensure the strength of the pull plate 2 structure and the restraint force on the two side walls.

[0059] The reinforcing component is inserted into two opposite slide rails 1 by sliding at both ends of the pull plate 2, so that the two side walls extending in the extension direction of the box body 3 are connected, which can effectively improve the strength of the water tank and prevent the water tank from swelling and deformation due to high internal pressure.

[0060] An embodiment of the present application provides a water tank, comprising: a tank body 3; and the above-mentioned reinforcement assembly.

[0061] Specifically, the number of reinforcement components can be multiple groups, and the number of reinforcement components is selected according to the length of the box body 3. The longer the box body 3 is, the more reinforcement components are needed. The water heater tank generally adopts a thin structure, which is not easy to swell in the width direction, so there is no need to constrain the width direction of the box body 3.

[0062] An embodiment of the present application provides a water heater, comprising the above-mentioned water tank.

[0063] like Figure 1 and 7 As shown, in the present application, the water heater further includes a heat exchange tube 4, a heater 5, etc. disposed in the water tank, the heat exchange tube 4 and the heater 5 are integrated on the bottom cover 31, the bottom cover 31, the heat exchange tube 4, the heater 5 and the pull plate 2 together constitute the bottom cover 31 component, and then the barrel body 32 is sleeved on the outside of the bottom cover 31 component, so that the pull plate 2 and the slide rail 1 are slidably matched. The two side walls of the barrel body 32 with larger areas are tightened by the pull plate 2, so as to prevent the side walls of the box body 3 from bulging and deforming.
