Specifically, the temperature sensor 37 is set to about 45℃, which is suitable for most people's taste temperature requirement.

[0038] Further, due to the principle of heat rising, the water temperature at the upper part of the water tank is higher than that at the lower part, the heating device 31 in the second water collecting tank 3 is located at the lower part of the second water collecting tank 3, specifically, at a position lower than one fourth of the height of the second water collecting tank 3, and the temperature sensor 37 is located at the same height as the heating device 31, for detecting the water temperature at the bottom of the second water collecting tank 3, to ensure that the water temperature at the upper part and the lower part of the whole water tank can reach the set value, to meet the demand of multiple users using water at the same time.

[0039] Further, in order to avoid breeding bacteria and improve the quality of drinking water, the ultraviolet sterilizer 121 is arranged on the water outlet pipe 12 of the machine box, for sterilizing and disinfecting the passing water.

[0040] Further, the warm water machine is provided with a water supplement system 6, when the water level in the second water collecting tank 3 is lower than a certain height, water is supplemented from the first water collecting tank 2 to the second water collecting tank 3.

The warm water supplement electromagnetic valve 151 is arranged on the warm water input pipe 15, the first sensor 62 and the second sensor 63 are both arranged in the inner container 35, and the installation height of the first sensor 62 is higher than that of the second sensor 63, and the water pump start-stop sensor 52 is located between them. Specifically, the first sensor 62 is located at the height close to the top of the inner wall of the second water collecting tank 3, the second sensor 63 is located at the height close to the temperature sensor 37, and the water pump start-stop sensor 52 is adjacent to the second sensor 63 and located above it, when the water level in the second water collecting tank 3 is lower than the water pump start-stop water level 52, the controller controls the variable frequency water pump 5 to stop outputting warm water to the user end, and when the water level in the second water collecting tank 3 is lower than the second sensor 63, the controller controls the warm water supplement electromagnetic valve 151 to open, so that warm water is supplemented to the second water collecting tank 3, until the water level reaches the position of the first sensor 62, and the water inlet is stopped.

[0041] As Figure 3As shown, the second water collecting tank 3 is a warm water storage tank, which has the function of storing the cooled drinking water, and is provided with an outer shell 34 and an inner container 35. The heat preservation layer 32 and the heat insulation layer 33 between the outer shell 34 and the inner container 35 are used for heat preservation of the water inside. Specifically, the inner container 35 is installed on the inner wall bottom of the outer shell 34 through a load bearing pad 36, the load bearing pad 36 completely overlaps the bottom of the inner container 35, and the material of the load bearing pad 36 is polytetrafluoroethylene. The heat insulation layer 33 is tightly attached to and surrounds the four sides and the top of the inner container 35. The heat preservation layer 32 surrounds the outside of the heat insulation layer 33. Specifically, the outer shell 34 and the inner container 35 are made of stainless steel to meet the food material standard. The heat insulation layer 33 is polyurethane foam. The heat preservation layer 32 is composed of a plurality of air bags. The air bags are tightly attached to each other between adjacent air bags in the heat preservation layer 32, and the shape of the air bags changes with the space. When the air bags are placed in the heat preservation layer 32, the air bags are tightly attached to the outer shell 34 on one side and the heat preservation layer 32 on the other side due to the inward pressure of the outer shell 34 and the heat insulation layer 33, that is, a layer of air bag layer is formed between the outer shell 34 and the heat insulation layer 33 to further heat preserve the inner container 35, thereby reducing the number of repeated heating and boiling of the heating device 31 in the second water collecting tank 3, ensuring the taste of the drinking water and improving the energy saving effect.

[0042] Further, in order to improve the heat preservation of the inner container 35 and improve the drinking water hygiene standard in the inner container 35, a heat preservation coating is sprayed on the inner wall of the inner container 35, and the heat preservation coating is a silver coating.
