Problems solved by technology
The disadvantage is that the price is high, the heating is diffuse, and it takes up space, so it is not suitable for families with a large population.
The advantages of instant water heaters are convenient, time-saving, space-saving, safe, and minimize heat loss. The disadvantages are that they are expensive and have high requirements for electric meters and wires. Generally, at least 30 amp electric meters, 4 Copper wire with a square millimeter cross-section, so it is inconvenient for families living in old houses

Embodiment Construction
[0009] Below in conjunction with accompanying drawing, the present invention is further described: in controller, be provided with microcomputer controller 4, it is connected with temperature relay 7, by inputting parameters such as bathing time, bathing temperature and mixing water ratio, microcomputer controller 4 can calculate storage temperature. The amount of cold water to be fed into the water tank 2 and the temperature to be heated are controlled through the cold water inlet 1. When the water is heated to the required temperature, the temperature relay 7 disconnects the heating circuit 6, and the hot water flows out through the hot water outlet pipe 3 to the water mixing valve. 5 Mix the water according to the set ratio, the water mixing valve 5 is connected to the microcomputer controller 4, when changing the parameters or manually adjusting the water mixing ratio, the microcomputer controller 4 receives the signal and transmits the signal to the temperature relay 7 to m...

The invention provides an automatic water heater which mainly comprises a heater, a water storage tank and a controller which is provided with a microcomputer controller that is connected with a temperature relay. After parameters such as bathing time, bathing temperature, mixing water proportion and the like are input, the microcomputer controller can calculate the requested amount of cold water into the water storage tank and the requested heating-up temperature, when the water is heated to the requested temperature, the temperature relay cuts off a heating circuit, a water mixing valve is connected with the microcomputer controller, and when the parameters are changed or the mixing water proportion is regulated manually, the microcomputer controller receives a signal and transmits the signal to the temperature relay so as to close the heating circuit. The beneficial effects of the automatic water heater are as follows: the usage of the water heater is quantified, thus saving the electricity; and the temperature relay ensures the water heater to be controlled conveniently, thus avoiding unnecessary heat source waste.
Description
technical field [0001] The invention relates to a water heater, especially an automatic water heater. Background technique [0002] Water heaters can be divided into three types: electric water heaters, gas water heaters, and solar water heaters according to different principles. Electric water heaters are divided into storage type and instantaneous type, also known as fast electric water heaters. Electric water heaters are characterized by easy use, energy saving and environmental protection, and continuous supply of hot water. Classification of gas water heaters: according to the type of gas used: artificial gas water heaters, natural gas water heaters, liquefied petroleum gas water heaters; according to the control method can be divided into: front-standard water heaters and rear-standard water heaters. According to the way of supply and exhaust, it can be divided into: direct exhaust type, flue type, forced exhaust type, balanced type, forced supply and exhaust type; ac...
