Description

Technical Field

[0001] This utility model relates to the field of heat pump water tank protection technology, specifically to a heat pump water tank explosion-proof device and a heat pump water tank. Background Technology

[0002] During operation, as the water temperature gradually heats from a low to a high temperature, the water vapor pressure increases significantly. This pressure change creates significant internal pressure inside the tank, making it particularly susceptible to expansion and deformation, especially for larger diameter tanks. There is even a potential risk of bursting due to excessive expansion.

[0003] In the explosion-proof design of traditional heat pump water tanks, safety valves are typically used as pressure control devices. When the system pressure exceeds a preset threshold, the safety valve will automatically open to release the pressure, thereby effectively preventing explosions. However, for water tanks with larger diameters, due to their large size and uneven stress distribution, the tank structure may still experience localized deformation even before the system pressure reaches the safety valve's opening threshold, posing a certain safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof device for a heat pump water tank and a heat pump water tank, which has a buffering and fixing function, and can prevent deformation caused by excessive pressure during the expansion of the water tank body, thereby improving the safety of use.

The explosion-proof clamp is arranged around the outer peripheral wall of the water tank body, and the locking assembly is used to lock and fix the first end and the second end so that the buffer member is tightly attached to the outer peripheral wall of the water tank body.

[0019] In an optional embodiment, the number of the heat pump water tank explosion-proof devices is multiple, and the multiple heat pump water tank explosion-proof devices are spaced apart along the length direction of the water tank body.

[0020] The beneficial effects of this utility model embodiment include:

[0021] The explosion-proof device for a heat pump water tank includes an explosion-proof clamp, a buffer, and a locking assembly. The explosion-proof clamp has a first end and a second end that are disposed opposite to each other. The buffer is disposed on the inner side wall of the explosion-proof clamp and is used to fit against the outer peripheral wall of the water tank body. The locking assembly is disposed on the first end or the second end and is used to lock and fix the first end and the second end.

[0022] During assembly, the explosion-proof clamp is wrapped around the outer perimeter of the water tank body, ensuring the buffer component fits snugly against the outer perimeter.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] As described in the background section, in the explosion-proof design of traditional heat pump water tanks, a safety valve is typically used as a pressure control device. When the system pressure exceeds a preset threshold, the safety valve will automatically open to release the pressure, thereby effectively preventing explosions. However, for water tanks with larger diameters, due to their large size and uneven stress distribution, the tank structure may still experience localized deformation even before the system pressure reaches the safety valve's opening threshold, posing a certain safety hazard.

[0038] Based on this, please refer to Figures 1-5 This utility model provides an explosion-proof device 100 for a heat pump water tank and a heat pump water tank 1000, which can effectively improve the aforementioned technical problems. Specifically, it has a buffering and fixing function, preventing deformation caused by excessive pressure during the expansion of the water tank body 200, thus improving safety. The explosion-proof device 100 and the heat pump water tank 1000 will be described in detail below.

[0039] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the heat pump water tank 1000 provided in this embodiment, combined with... Figure 1 The heat pump water tank 1000 includes a heat pump water tank explosion-proof device 100 and a water tank body 200. The heat pump water tank explosion-proof device 100 is installed on the outer peripheral wall of the water tank body 200 and can play a role in preventing the water tank body 200 from deformation and bursting.

[0040] Please refer to Figure 2 , Figure 2 This is an exploded view of the heat pump water tank explosion-proof device 100 provided in this embodiment, combined with... Figure 1 and Figure 2 The heat pump water tank explosion-proof device 100 includes an explosion-proof clamp 10, a buffer 20, and a locking assembly 30. The explosion-proof clamp 10 is used to surround the outer peripheral wall of the water tank body 200. The buffer 20 is disposed on the inner side wall of the explosion-proof clamp 10 and is located between the explosion-proof clamp 10 and the water tank body 200. The buffer 20 is used to fit against the outer peripheral wall of the water tank body 200.

[0041] For details, please refer to Figure 3 and Figure 4 , Figure 3 This is a first-view structural schematic diagram of the explosion-proof clamp 10 provided in this embodiment. Figure 4 This is a second-view structural schematic diagram of the explosion-proof clamp 10 provided in this embodiment. (Combined with...) Figures 1-4 The explosion-proof clamp 10 has a first end 11 and a second end 12 disposed opposite to each other, and a locking component 30 is disposed on the first end 11 or the second end 12 and is used to lock and fix the first end 11 and the second end 12.

[0042] In other words, during assembly, the explosion-proof clamp 10 is wrapped around the outer peripheral wall of the water tank body 200, so that the buffer 20 fits snugly against the outer peripheral wall of the water tank body 200. Then, the locking assembly 30 locks and fixes the first end 11 and the second end 12, so that the explosion-proof clamp 10 is locked and fixed to the outer peripheral wall of the water tank body 200, thereby pressing the buffer 20 tightly against the outer peripheral wall of the water tank body 200. It is easy to understand that through the combined action of the explosion-proof clamp 10 and the buffer 20, the outer periphery of the water tank body 200 is wrapped, simultaneously providing cushioning and fixation for the water tank body 200. This prevents deformation caused by excessive pressure during the instantaneous expansion of the water tank body 200, thus improving safety during use.

[0043] Please continue to combine Figure 1 In order to achieve explosion-proof and deformation-proof functions at different positions of the water tank body 200 and further improve the safety of the heat pump water tank 1000, the number of heat pump water tank explosion-proof devices 100 can be set to multiple, and multiple heat pump water tank explosion-proof devices 100 are spaced apart along the length of the water tank body 200.

[0044] It should be noted that the length of the water tank body 200 mentioned above refers to... Figure 1 The X direction is shown in the figure; of course, if the water tank body 200 is cylindrical in shape, then this length direction can be understood as the axial direction of the water tank body 200.

[0045] In addition, it should be noted that in this embodiment, the number of explosion-proof devices 100 for the heat pump water tank is four. Of course, in other embodiments, the number can be one, two, three or five, etc. The specific number needs to be determined according to the length of the water tank body 200, the actual use, or the design requirements.

[0046] Please continue to combine Figure 2 In this embodiment, the buffer 20 is bonded to the inner wall of the explosion-proof clamp 10, which improves the fixing effect of the buffer 20 and ensures that it can better buffer when the water tank body 200 expands, making it less likely to shake and detach. Specifically, glue or double-sided tape can be applied to the inner wall of the explosion-proof clamp 10 before bonding the buffer 20; of course, double-sided tape or glue can also be applied directly to the buffer 20 before pasting it to the inner wall of the explosion-proof clamp 10.

[0047] It should be noted that in some other embodiments, the buffer 20 and the explosion-proof clamp 10 can also be connected and fixed in other ways. For example, in other embodiments, the inner sidewall of the explosion-proof clamp 10 and one of the buffer 20 are provided with a slot (not shown in the figure), and the inner sidewall of the explosion-proof clamp 10 and one of the buffer 20 are provided with a snap-fit ​​protrusion (not shown in the figure), which engages with the slot.

[0048] In addition, it should be noted that the buffer 20 in this embodiment is specifically polyethylene foam, which has good impact absorption capacity and can effectively absorb and disperse impact energy; it also has the characteristics of heat insulation, sound insulation and noise reduction, and waterproof and moisture-proof properties. Of course, in some other embodiments, the buffer 20 may also be a structure of other buffer materials such as polystyrene foam or pearl cotton.

[0049] Further, please refer to Figure 5 , Figure 5 for Figure 2 A magnified view of a section at point A, combined with Figures 2-5 The locking assembly 30 includes a screw 31 and a nut 32. One of the first end 11 and the second end 12 has a mounting hole 13, and the other of the first end 11 and the second end 12 has a screw 31. The screw 31 is used to pass through the mounting hole 13 and is threadedly connected to the nut 32.

[0050] Specifically, in this embodiment, the screw 31 is disposed at the first end 11, and the second end 12 has an assembly hole 13. Of course, in other embodiments, the screw 31 can also be disposed at the second end 12, with the corresponding assembly hole 13 at the first end 11.

[0051] In order to adapt to water tank bodies 200 of different sizes and specifications and improve the versatility and adaptability of heat pump water tank explosion-proof device 100, in this embodiment, there are multiple mounting holes 13, which are spaced apart along the extension direction of the first end 11 or the second end 12.

[0052] Furthermore, the locking assembly 30 also includes a spring washer 33, which is fitted onto the screw 31 and located on the side of the nut 32 near the first end 11 or the second end 12. By providing the spring washer 33, a spring force can be provided to the nut 32 and it can be pressed against the nut 32, making it less likely to fall off, thereby further improving the fastening effect on the water tank body 200; at the same time, the spring force of the spring washer 33 can also play a role in buffering and shock absorption, so that it can cooperate with the explosion-proof clamp 10 and the buffer 20 to a certain extent to prevent the water tank body 200 from deforming.

[0053] Furthermore, the locking assembly 30 also includes a flat washer 34, which is fitted onto the screw 31 and located on the side of the nut 32 near the first end 11 or the second end 12. Specifically, in this embodiment, the flat washer 34 is located between the second end 12 and the spring washer 33. By providing the flat washer 34, the contact area between the nut 32 or the spring washer 33 and the second end 12 can be increased to distribute pressure, thereby protecting the second end 12. It can also adjust the connection gap of the nut 32 or the spring washer 33, improving connection stability.

[0054] In summary, the embodiments of this utility model provide a heat pump water tank explosion-proof device 100 and a heat pump water tank 1000. The heat pump water tank explosion-proof device 100 includes an explosion-proof clamp 10, a buffer member 20, and a locking assembly 30. The explosion-proof clamp 10 has a first end 11 and a second end 12 disposed opposite to each other. The buffer member 20 is disposed on the inner side wall of the explosion-proof clamp 10 and is used to fit against the outer peripheral wall of the water tank body 200. The locking assembly 30 is disposed on the first end 11 or the second end 12 and is used to lock and fix the first end 11 and the second end 12. During assembly, the explosion-proof clamp 10 is placed around the outer peripheral wall of the water tank body 200, so that the buffer 20 fits against the outer peripheral wall of the water tank body 200. Then, the first end 11 and the second end 12 are locked and fixed by the locking assembly 30, so that the explosion-proof clamp 10 is locked and fixed on the outer peripheral wall of the water tank body 200, thereby making the buffer 20 fit tightly against the outer peripheral wall of the water tank body 200.

[0055] As is easily understood, the combination of the explosion-proof clamp 10 and the buffer 20 can wrap around the outer periphery of the water tank body 200, which can simultaneously buffer and fix the water tank body 200, thereby preventing deformation caused by excessive pressure during the expansion of the water tank body 200 and improving the safety of use.

[0056] The heat pump water tank 1000 includes a heat pump water tank explosion-proof device 100, which has all the functions and beneficial effects of the heat pump water tank explosion-proof device 100.
