Description

Electric kettle capable of quickly cooling

Technical Field

The utility model relates to the field of electric heating kettle bodies, in particular to an electric heating kettle capable of quickly cooling.

Background

In the prior art, the traditional electric kettle only has the function of boiling water, the electric kettle is automatically powered off after the water is boiled, the boiled water is cooled in the nature, and the temperature suitable for drinking can be reached after long-time waiting. For example, the milk powder needs to be dissolved, boiled water with the temperature of about 55 ℃ needs to be taken, and the milk powder can be used after natural cooling or other physical cooling is adopted for a long time.

One of the existing products is a product which can be drunk after water is boiled by heating a heating pipe. Without a cooling device, the water is cooled to a temperature suitable for drinking by natural cooling. This product relies on natural cooling owing to do not have the heat sink, and the cooling time is too of a specified duration, can not in time drink the water of suitable temperature.

The second existing product is that the direct drinking cold water is heated to the temperature without reaching boiling. The product only heats direct drinking cold water to a proper temperature, and the water is not boiled and does not belong to boiled water. The direct drinking cold water has influence on human health under the condition that the water quality does not reach the standard.

Third, some rapid cooling electric kettle has appeared in the technique among the current product, including kettle base, main part, be equipped with the air supply passageway of fan and kettle bottom on the base, after the water boils in the main part, through driving the fan and rotate and blow to the kettle bottom air supply passageway in, realize the cooling purpose, for example the hot-water kettle that application number is 201310621280.3. This product is because this radiating mode inefficiency, and the unable quick absorption of heat and release, waiting time can not drink the water that is fit for the temperature fast for a long time.

In the fourth existing product, for example, the water-cooled electric kettle structure with application number 202010489471.9, when the kettle is connected to the heating base, the water supply joint and the water return joint are respectively communicated with the corresponding one-way water valve, so that the water tank, the water pump and the accommodating cavity can form a circulating water path; after the water supply kettle of the heating base is electrified to heat water, when the boiled water needs to be cooled by the boiled water; the water pump is started, the water pump pumps water in the water tank into the accommodating cavity through one-way water valve and returns to the water tank from the other one-way water valve, so that a circulating water path is formed, boiled water in the kettle is cooled through circulating water, and the cooling speed of the boiled water is accelerated. Because the holding cavity is integral, when water in the water tank is conveyed into the holding cavity through the water pump, the water is gradually raised and filled in the holding cavity, and in the process, the bottom of the water temperature in the kettle is obviously higher than the top of the water temperature. When the water in the containing cavity is full, the replacement rate of the water in the inner lower end part and the water in the water tank is obviously greater than that of the water in the upper end part and the water in the water tank. This can obviously result in a large temperature difference in the water in the kettle, thereby affecting the taste and efficacy of the particular product.
