Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to a corner connection structure for a water heater casing. Background Technology

[0002] An air source heat pump water heater is a device that uses an air source heat pump to heat water, primarily for domestic hot water supply. Its working principle is based on the reverse Carnot cycle; the compressor absorbs heat energy from the air, which is then transferred to the water tank via a refrigerant to heat the cold water. It can achieve a constant temperature water supply around the clock without direct sunlight.

[0003] As users' aesthetic standards improve, they have higher and higher requirements for the appearance of water heater casings, hoping to reduce the exposure of screws within the visible range and make the overall appearance of the panel surface more aesthetically pleasing.

[0004] Existing water heaters typically have a partition inside the cavity, dividing it into upper and lower chambers. The upper chamber houses the compressor, heat exchanger, and fan, with the partition serving as a load-bearing element. The lower chamber houses the water tank. Furthermore, user preferences vary; some prefer right angles on the front panel corners, while others prefer curved corners. To accommodate these preferences and reduce mold costs for the partition, the corresponding corners are designed to be curved, allowing the partition to be used in both right-angle and curved-corner water heaters. However, as mentioned above, when the partition is used in a right-angle water heater with a curved corner, a gap is created between the curved corner of the partition and the right-angle corner of the water heater. This results in insufficient load-bearing capacity of the partition at the corner, indicating a design flaw. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a corner connection structure for the casing of a water heater, which solves the problem of insufficient load-bearing capacity of the partition of the water heater at the corner in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a corner connection structure for a water heater casing, including a casing, a partition, and a panel. The front of the casing has an opening, and the left and right sides of the opening are bent towards the inner cavity of the casing to form first folded edges. The partition is installed in the inner cavity of the casing, and the edge of the partition is bent upward to form a second folded edge. The corner connection structure also includes two corner brackets, which are fixed at two corners of the partition near the opening. One end of each corner bracket is connected and fixed to the first folded edges on both sides, and the other end of each corner bracket is connected and fixed to the second folded edge at the front end of the partition. The panel is installed at the opening.

[0007] As a further embodiment, the corner bracket includes a connecting part and fixing parts located at both ends of the connecting part. The connecting part and the fixing parts at both ends are integrally formed. The connecting part is fixed to the second folded edge of the partition near the corner by a first fastener. The fixing parts at both ends of the connecting part are fixed to the first folded edge and the second folded edge at the front end of the partition by second fasteners, respectively.

[0008] As a further embodiment, the connecting part is in the form of a sheet, and reinforcing ribs are bent on both the upper and lower sides of the connecting part. The reinforcing ribs can be welded to the fixing part at one end of the connecting part.

[0009] As a further embodiment, the fixing parts at both ends of the connecting part are both plate-shaped, and the fixing parts at both ends of the connecting part are parallel to each other.

[0010] As a further embodiment, the partition divides the opening into an upper opening and a lower opening, with a support member at the bottom of the lower opening and several insertion holes on the support member. The panel includes an upper panel and a lower panel. Several plugs are fixed on the reverse side of the lower panel near the bottom. The plugs can be inserted into the sockets. The top of the lower panel is bent toward the lower opening to form a third folded edge. The third folded edge is fixed to the second folded edge at the front end of the partition by a third fastener. The top of the upper panel is bent toward the upper opening to form a fourth folded edge, and the two sides of the upper panel are bent toward the upper opening to form a fifth folded edge. The fourth folded edge is fixed to the top cover of the housing by a fourth fastener. The two fifth folded edges are respectively fixed to the first folded edges on both sides of the opening by a snap-fit ​​structure to cover the corner bracket, the second folded edge, and the third folded edge.

[0011] As a further solution, the two sides of the lower panel are bent toward the lower opening to form a sixth fold, and the sixth folds on both sides are fixed to the first folds on both sides of the opening by a snap-fit ​​structure.

[0012] The beneficial effects of this utility model are as follows: by fixing two corner brackets at the two corners of the partition near the opening, one end of each corner bracket is connected and fixed to the first folded edge on both sides, and the other end of each corner bracket is connected and fixed to the second folded edge at the front of the partition. By connecting and fixing the corner of the partition to the second folded edge at the front of the partition and the first folded edge on the opening side through the corner brackets, the load at the corner is transferred to the second folded edge at the front of the partition and the first folded edge on the opening side, thereby enhancing the load-bearing capacity at the corner of the partition.

Furthermore, in the description of this application, the terms "first," "second," "third," "fourth," "fifth," "sixth," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0017] As attached Figure 1-2As shown, this utility model provides a corner connection structure for a water heater casing, including a casing 1, a partition 2, and a panel 3. The casing 1 has an opening 11 on its front, allowing the user to easily inspect and repair the interior of the casing 1. The left and right sides of the opening 11 are bent towards the interior of the casing 1 to form first folded edges 12. The partition 2 is installed and fixed within the interior of the casing 1, and its edges are bent upwards to form second folded edges 21. The corner connection structure also includes two corner brackets 4, which are fixed at two corners of the partition 2 near the opening 11. One end of each corner bracket 4 is connected and fixed to the first folded edges 12 on both sides, and the other end is connected and fixed to the second folded edge 21 at the front end of the partition 2. The panel 3 is installed at the opening 11. Specifically, the two corner brackets 4 are fixed to the two corners of the partition 2 near the opening 11 by screws. One end of the two corner brackets 4 is connected and fixed to the first folded edge 12 on both sides by screws, while the other end of the two corner brackets 4 is connected and fixed to the second folded edge 21 at the front end of the partition 2 by screws.

[0018] In this embodiment, by fixing two corner brackets 4 at the two corners of the partition 2 near the opening 11, one end of each corner bracket 4 is connected and fixed to the first folded edge 12 on both sides, and the other end of each corner bracket 4 is connected and fixed to the second folded edge 21 at the front end of the partition 2. By connecting and fixing the corner of the partition 2 to the second folded edge 21 at the front end of the partition 2 and the first folded edge 12 on the side of the opening 11 through the corner brackets 4, the load at the corner is transferred to the second folded edge 21 at the front end of the partition 2 and the first folded edge 12 on the side of the opening 11, thereby enhancing the load-bearing capacity at the corner of the partition 2.

[0019] It is worth noting that, as shown in the attached document Figure 3 , 6 As shown, the corner bracket 4 includes a connecting part 41 and fixing parts 42 located at both ends of the connecting part 41. The connecting part 41 and the fixing parts 42 at both ends are integrally formed. The connecting part 41 is fixed to the second folded edge 21 near the corner of the partition plate 2 by a first fastener. The fixing parts 42 at both ends of the connecting part 41 are fixed to the first folded edge 12 and the second folded edge 21 at the front end of the partition plate 2 by second fasteners, respectively. Specifically, both the first fastener and the second fixing part can be screws. The fixing parts 42 at both ends of the connecting part 41 are both plate-shaped and parallel to each other. The corner bracket 4 is Z-shaped, so it can be adapted to the shape of the corner of the partition plate 2, making it easy to connect with the first folded edge 12 and the second folded edge 21 at the front end of the partition plate 2.

[0020] It should be noted that, as shown in the attached document... Figure 6As shown, the connecting part 41 is plate-shaped, and reinforcing ribs 43 are bent on both the upper and lower sides of the connecting part 41. The reinforcing ribs 43 can be welded to the fixing part 42 at one end of the connecting part 41. The reinforcing ribs 43 can enhance the load-bearing capacity of the connecting part 41 and prevent the connecting part 41 from deforming under stress.

[0021] In some embodiments, as shown in the appendix Figure 2 , 4 As shown in Figure 5, the partition 2 divides the opening 11 into an upper opening 111 and a lower opening 112. A support member 5 is provided at the bottom of the lower opening 112, and the support member 5 has several insertion holes 51. Specifically, the support member 5 is fixed to the bottom of the lower opening 112 by screws. The panel 3 includes an upper panel 31 and a lower panel 32. Several plugs 321 are fixed to the reverse side of the lower panel 32 near the bottom. The plugs 321 can be inserted into the insertion holes 51, thereby fixing the bottom of the lower panel 32. Since the plugs 321 are located on the reverse side of the lower panel 32, the lower panel 32 can conceal the plugs 321 inserted into the insertion holes 51, which is more aesthetically pleasing. The top of the lower panel 32 is bent downwards from the opening 112 to form a third folded edge 322. The third folded edge 322 is fixed to the second folded edge 21 at the front end of the partition 2 by a third fastener, thereby fixing the top of the lower panel 32. Furthermore, the lower panel 32 can bear the weight of the front end of the partition 2. The top opening 111 of the upper panel 31 is bent upwards to form a fourth folded edge 311, and the two sides of the upper panel 31 are bent upwards to form a fifth folded edge 312. The fourth folded edge 311 is fixed to the top cover 13 of the housing 1 by a fourth fastener, thereby installing the upper panel 31 at the upper opening 111. The upper panel 31 also covers the corner bracket 4, the second folded edge 21, and the third folded edge 322, thus avoiding exposed screws and making the overall appearance more aesthetically pleasing. Screws can be used for the third and fourth fasteners.

[0022] Furthermore, the fifth folded edges 312 on both sides are fixed to the first folded edges 12 on both sides of the opening 11 by a snap-fit ​​structure. The two sides of the lower panel 32 are bent downwards through the opening 112 to form sixth folded edges 323, and the sixth folded edges 323 on both sides are fixed to the first folded edges 12 on both sides of the opening 11 by a snap-fit ​​structure. It should be noted that the above-mentioned snap-fit ​​structure is a combination of snap-fit ​​and snap-hole fixing. By setting snap-fit ​​on the upper panel 31 and the lower panel 32, and setting snap-hole on the first folded edges 12 on both sides of the opening 11, the snap-fit ​​and snap-hole cooperate to fix the upper panel 31 and the lower panel 32 to the upper opening 111 and the lower opening 112, respectively.
