[0042] like Figure 1-Figure 5 As shown, this embodiment provides a water tank assembly, which includes a water tank assembly 100, a heat insulating member 200, a connecting assembly 300 and a top cover 400. The water tank assembly 100 includes an outer shell 110 and an inner tank 120 disposed in the outer shell 110; the heat insulating member 200 is disposed in the outer shell 110; the connecting assembly 300 is used to connect the inner tank 120 and the heat insulating member 200; the top cover 400 is covered on the outer shell 110, and a connecting member 111 is disposed on the inner wall of the outer shell 110, and an avoidance groove 210 is disposed circumferentially of the heat insulating member 200, and the connecting member 111 can be placed in the avoidance groove 210 and connected to the top cover 400.

[0043] The inner tank 120 of the water tank assembly is arranged in the outer shell 110, and the heat insulation member 200 is arranged between the outer shell 110 and the top cover 400. By setting the heat insulation member 200, it is beneficial to reduce the heat exchange between the inner tank 120 and the top cover 400, thereby effectively reducing the heat loss of the inner tank 120 and improving the thermal insulation performance of the water tank assembly. The top cover 400 is covered on the outside of the outer shell 110 and is connected to the connecting piece 111 on the inner wall of the outer shell 110, thereby realizing the connection between the top cover 400 and the outer shell 110; the thermal insulation member 200 is connected to the inner tank 120 through the connecting assembly 300, and has no connection relationship with the top cover 400, thereby reducing the damage to the thermal insulation member 200 caused by the connection; at the same time, the thermal insulation member 200 is circumferentially provided with an avoidance groove 210. When connecting the top cover 400 and the outer shell 110, the connecting piece 111 can be placed in the avoidance groove 210, so that the connection process will not cause any damage to the thermal insulation member 200, thereby ensuring the thermal insulation effect of the thermal insulation member 200 and effectively improving the thermal insulation performance of the water tank assembly.

[0044] Specifically, both ends of the connecting piece 111 are penetrated and have internal threads, and the side wall of the outer shell 110 is provided with a connecting hole connected to the inner cavity of the connecting piece 111, wherein the setting of the internal thread and the connecting hole enables the connection between the outer shell 110 and the top cover 400 to be achieved by bolts, and the connecting hole is used to avoid the bolts, and the threaded connection is more reliable and easy to disassemble.

[0045] In this embodiment, the connector 111 is riveted to the housing 110 and protrudes from the inner wall of the housing 110. The connection between the riveted connector 111 and the housing 110 is more reliable. Since the connector 111 protrudes from the inner wall of the housing 110, the top cover 400 can be sleeved on the housing 110 without interfering with the connector 111.

[0046] Preferably, the avoidance groove 210 is arranged through the heat insulating member 200, so that when the heat insulating member 200 is installed in the housing 110, it does not interfere with the connecting member 111. It is worth noting that the arrangement of the avoidance groove 210 allows the connecting member 111 to be riveted first in the housing 110, and then the heat insulating member 200 is installed, without causing damage to the heat insulating member 200, and the installation process is more reasonable.

[0047] Optionally, more than two connectors 111 are evenly spaced along the circumference of the housing 110. By providing multiple connectors 111, the connection between the top cover 400 and the housing 110 is more reliable; and multiple connectors 111 are evenly spaced along the circumference of the housing 110, so that the forces on the multiple connectors 111 are more uniform.

[0048] In one embodiment, a guide section 220 is provided at one end of the heat insulating member 200 close to the inner liner 120, and the guide section 220 is narrowed in the direction close to the inner liner 120. The guide section 220 is provided to guide the heat insulating member 200 when it is installed in the outer shell 110, which is beneficial to improve the alignment between the heat insulating member 200 and the outer shell 110 after installation. It can be understood that the avoidance groove 210 runs through the side wall of the guide section 220 to ensure that when the heat insulating member 200 is placed in the outer shell 110, the connecting member 111 will not damage the guide section 220 of the heat insulating member 200.

[0049] Specifically, the connection assembly 300 includes a connection plate 310 and a pressure plate 320. The connection plate 310 is arranged between the heat insulating member 200 and the inner tank 120. The pressure plate 320 is arranged between the connection plate 310 and the heat insulating member 200, and is used to connect the connection plate 310 and the water tank assembly 100. Exemplarily, a flange 121 and a connecting column 122 are arranged on the inner tank 120. During installation, the connection plate 310 and the pressure plate 320 are placed on the inner tank 120 in sequence, and then the pressure plate 320 is connected to the flange 121 by a nut 321, and then the pressure plate 320 and the connection plate 310 are further connected by a self-tapping screw 322, so that the connection between the inner tank 120, the connection plate 310 and the pressure plate 320 is more reliable.

[0050] Furthermore, a mounting groove 230 is provided on one side of the heat insulating member 200 close to the connecting plate 310, and at least a portion of the connecting plate 310 can be placed in the mounting groove 230. Figure 2 and Figure 4 As shown, the shape of the mounting groove 230 is adapted to the connecting plate 310. After the liner 120, the connecting plate 310 and the pressing plate 320 are installed, the connecting plate 310 is at least partially placed in the mounting groove 230. It is worth noting that the thermal insulation member 200 and the connecting plate 310 are connected by foaming. Therefore, the setting of the mounting groove 230 can not only be used to position the thermal insulation member 200, but also facilitate the subsequent foaming connection, which is convenient for improving production efficiency and saving production costs. Preferably, the connecting plate 310 and the pressing plate 320 are both placed in the mounting groove 230.

[0051] In this embodiment, the connection assembly 300 further includes a mounting tray 330, which is disposed at one end of the heat insulating member 200 away from the inner tank 120, and the mounting tray 330 is connected to both the heat insulating member 200 and the connection plate 310. The provision of the mounting tray 330 is not only conducive to protecting the heat insulating member 200, but is also used for the installation of the water tank assembly and other components of the heat pump water heater. Optionally, a connecting bolt 331 is provided on the mounting tray 330, and a through hole is provided on the heat insulating member 200. The connecting bolt 331 can pass through the through hole and be threadedly connected to the connection plate 310, so as to improve the reliability of the connection between the mounting tray 330, the heat insulating member 200 and the connection assembly 300.

[0052] Preferably, a weight-reducing groove 240 is provided on the thermal insulation member 200, which is beneficial to reducing the weight of the water tank assembly; and / or, an avoidance hole 250 is provided on the thermal insulation member 200 for avoiding other components on the installation tray 330, which is also beneficial to reducing the weight of the water tank assembly.

[0053] This embodiment also discloses a heat pump water heater, comprising a main unit and a water tank assembly as described in any of the above schemes, wherein the main unit is at least partially disposed on the top cover 400. In the heat pump water heater provided with the above water tank assembly, an avoidance groove 210 is disposed on the heat insulation member 200, so that the heat insulation member 200 will not be damaged during the installation of the top cover 400 and the housing 110 of the water tank assembly, thereby ensuring a good heat preservation effect of the water tank assembly, and further facilitating the improvement of the heating efficiency of the heat pump water heater.

[0054] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
