As shown in fig. 10, the buffering member 50 may further include a fixing portion 52, a lower end of the fixing portion 52 may be connected to a lower cavity wall surface of the tank cavity 101, and an upper end of the fixing portion 52 may be connected to an edge of the buffer plate, so that the buffering member 50 has a simple and stable structure and is easy to machine and mold. Alternatively, the fixing part 52 may include a first fixing plate extending in a vertical direction and a second fixing plate extending in a horizontal direction. The first fixing plate may be connected to the buffer plate, so that the buffer plate is spaced apart from the outlet 302 of the water inlet pipe by a predetermined distance, thereby preventing the buffer plate from being too close to the outlet 302 of the water inlet pipe to affect the water inlet efficiency. The second fixing plate can be in surface-to-surface contact with and welded to the wall surface of the lower cavity of the tank cavity 101, and the connection is firmer and more reliable. In addition, the fixing plate and the buffer plate can be formed by bending one plate body, so that the structure is simpler and firmer, and the processing is easier.

For example, in some embodiments, the distances L1 between the lowest point of the hot can drain opening 403 and the lower cavity wall of the can cavity 101 may be 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, and the like. Within the above size range, the lowest point of the hot tank drain opening 403 is closer to the wall surface of the lower cavity of the tank cavity 101, so that the liquid in the tank cavity 101 can be more sufficiently drained through the hot tank drain opening 403 during the cleaning process of the hot tank assembly 100, the liquid residue is less, and the tank cavity 101 is cleaned more cleanly. For example, in the example shown in fig. 3, the lowest point of the hot water tank drain 403 is flush with the lower cavity wall surface of the tank cavity 101, i.e. L1 is 0mm, so that the liquid in the tank cavity 101 can be completely drained from the hot water tank drain 403 during the cleaning process without residue, and the cleaned sewage is prevented from remaining and mixing with the drinking water during the water production of the hot water tank assembly 100.

In the present invention, the flow area of the outlet pipe 40 is S1, the flow area of the inlet 401 of the outlet pipe is S2, the flow area of the hot water outlet 403 of the hot water tank is S3, and S2 is S1, S3 is not more than 0.2 × S1. So that the inlet 401 of the water outlet pipe is large enough to ensure the water outlet efficiency and the exhaust efficiency, and the hot pot drain 403 can discharge sewage and has a small flow area S3, thereby reducing the amount of water flowing out of the hot pot drain 403 from the low-temperature water in the lower part of the pot cavity 101 and ensuring the effect of hot water output from the hot pot assembly 100.

In some embodiments of the present invention, as shown in fig. 2, the upper end of outlet pipe 40 is opened to form an outlet pipe inlet 401, the distance between the upper end of outlet pipe 40 and the upper cavity wall of tank cavity 101 is L2, and the distance between the upper cavity wall and the lower cavity wall of tank cavity 101 is L3, wherein L2 is not more than 0.1 × L3. Because the higher the water level in the tank cavity 101, the higher the water temperature, the closer the distance between the outlet pipe inlet 401 and the upper cavity wall surface of the tank cavity 101, the higher the relative temperature of the water output from the outlet pipe 40 can be, which is beneficial to ensuring the stability of the outlet water temperature of the hot tank assembly 100 and reducing the energy consumption.
