The water heating machine provided by the invention can provide boiling water within 3-5 seconds; has the advantages of simple structure, high stability and reliability, safety, hygiene, convenience for operation and zero idle power consumption; and is significant in market advantages.

Description

Technical field [0001] The invention provides a water boiling machine for rapidly dispensing boiled water, which belongs to small household appliances for boiling water. Background technique [0002] The water boiler is a commonly used electrical appliance. The usual structure is to use an electric heater to heat the water in the kettle container until the water is boiled. This kind of appliance is usually called a kettle. It is a very mature product. Simple, you need to wait for the water to boil, and usually you need to pour the water into a thermos for later use. [0003] In recent years, the new concept of instant boiling water has been proposed and widely recognized, and some practical technical solutions have been formed, which are mainly divided into two categories, one can be called the controlled water supply heating mode, and the other is the boiling overflow type. heating mode. [0004] The working principle of the controlled water supply heating mode is that th...

Problems solved by technology

[0004] The working principle of the controlled water supply heating mode is that the water flow is continuously heated through the electric heating body, and the water temperature reaches the required temperature when it flows out of the electric heating body, and the temperature is basically achieved by controlling the water flow, as disclosed on June 17, 2009 A scheme proposed by a patent whose notification number is CN101457977A, the water boiler is composed of a water tank, a water inlet pipe, a water pump, an electric heater, a water outlet pipe and a control circuit, and the flow of the water pump is controlled by the control circuit according to the temperature of the water outlet. The electric heating film on the substrate is used as the heating element. This technical solution has stable water output, but the disadvantage is that the pump is noisy, the output water temperature does not reach 100°C, and the manufacturing cost is high.

[0005] The working principle of the boiling overflow heating mode is that water rushes out of the heating chamber when the heating chamber is heated to boiling, and cold water is replenished from the cold water chamber through the bottom of the heating chamber. Balance, some schemes are realized by controlling the flow rate of the water pump on the water inlet pipe, such as the patent of CN201481086U published on May 26, 2010. This scheme needs to frequently start and stop the water pump or adjust the water pump, which is not perfect in practice; there are also schemes to control The solenoid valve on the water inlet pipe, such as the patent of CN2909090Y published on June 6, 2007, has the same advantages and disadvantages as the patent of CN201481086U; Boiling overflow heating mode, but the water inlet water level adopts a simple and reliable overflow control mode. In this mode, there is an overflow port in the water inlet chamber. When the water level exceeds the height of the overflow port, the water flows back from the overflow port. To the water tank, it limits the continuous rise of the water inlet level, ensures that the water inlet level does not exceed the height of the water outlet, and at the same time realizes the automatic balance of the water flow in the heating chamber of the water boiler
