Description

Technical Field

[0001] The utility model relates to the field of water heaters, in particular to an under-sink water heater. Background Art

[0002] A water heater is a very popular household appliance. Its working principle is that it is connected to the cold water supply pipe of the household. The cold water is heated to the set temperature after passing through the water heater tank, and then sent to various water use points in the household connected to the hot water pipe through the hot water pipe connected to it, such as the kitchen, bathroom, balcony, etc. These water use points can be installed with mixing faucets for switching between cold and hot water, which is very convenient to use.

[0003] At present, depending on the type of water heater, there are great differences in its installation location. For example, there are wall-mounted water heaters installed on indoor walls, and under-the-counter water heaters placed in cabinets. Among them, under-the-counter water heaters have the advantages of being small and light and taking up less space, and are becoming more and more popular among the public.

[0004] However, existing under-sink water heaters still have some problems. For example, in order to meet the needs of cabinet placement, it is usually necessary to reduce the volume as much as possible while maintaining the capacity. As the volume decreases, the quality will generally decrease. Moreover, the water heater is placed directly inside the cabinet, which may cause it to shake, collide, or even tip over, which may easily cause damage. There are certain shortcomings. At the same time, the environment inside the cabinet is also relatively complex. Combined with the fact that it is easy to be damaged, there are certain risks when using it. Utility Model Content
