Description
Technical Field
The invention relates to the technical field of cooling of hot water kettles, in particular to a hot water cooling system of an electric kettle.
Background
Nowadays, electric kettles are indispensable daily necessities for every family. However, the water boiled in the electric kettle needs to be placed in the air for a long time to be cooled to a temperature suitable for human body to drink. With the innovation of technology, heat-preservation electric kettles capable of adjusting water temperature appear on the market, but the cost is high and the occupied space is large. For example, CN201384388Y prior art discloses an automatic electric kettle capable of rapidly reducing the temperature of boiled water, which comprises a kettle body, an inner container disposed in the kettle body, a base disposed at the bottom of the kettle body, and a heating element for heating the inner container, wherein a fan for blowing air to the inner container and a control circuit thereof are also disposed in the kettle body. The fan is arranged in a cavity between the inner container and the base and is fixed on the base through a bracket, and air holes are arranged on the side surface of the kettle body and the base. The invention has simple structure, high cooling efficiency and simple control. The automatic electric kettle capable of quickly reducing the temperature of the boiled water achieves the effect of reducing the temperature, but cannot accurately display the temperature of the water in the inner container and cannot reduce the temperature according to different requirements of users. Especially when tea or other drinks are brewed, the water temperature is often inaccurately controlled, so that the nutritional value of the tea or other drinks is lost. Another typical prior art water kettle assembly, such as that disclosed in WO2008010749a1, is an open cooling cycle system in which the expansion kettle does not participate in the cooling cycle and is not subjected to the cooling system pressure, and in which the radiator assembly has a fill port in the water chamber through which coolant is filled, with a pressure cap over the fill port of the radiator. When the cooling system works normally, when the temperature of the cooling system rises and the pressure reaches a preset value, the pressure cover is opened, so that gas in the system enters the expansion kettle and is discharged into the atmosphere; when the cooling system is under negative pressure, water in the expansion kettle is sucked into the cooling circulation system. Meanwhile, the problem that the heat dissipation efficiency of the closed cooling circulation system is poor exists. Turning to a cooling mechanism such as that disclosed in the prior art of DE10117846(C1), the power supply is cut off by an automatic trip switch. When a user drinks water by using the existing electric kettle, the water in the kettle is firstly required to be boiled, then the user waits for a long time until the boiled water is cooled to a temperature suitable for drinking, and the user is inconvenient to use.
The invention is made in order to solve the problems of low cooling efficiency, complex structure, low heat dissipation efficiency and the like commonly existing in the field.
