Description

A tea set with a water volume detection mechanism in a water tank

technical field

The present invention relates to a tea set for making tea, in particular to a tea set with a water volume detection mechanism in a water tank.

Background technique

The structure of the existing tea making set includes a tea tray body. The tea tray body is provided with a tea tray surface for holding (infusing) teapots and teacups. The tea tray surface is provided with a sewage collection tank. One side of the tea tray body is used as an electric heating device. The electric heating device is mostly composed of an induction cooker and an electromagnetically heated kettle body; when in use, people first pour tap water into the kettle body, then place the kettle body on the surface of the induction cooker to heat it to boiling, and finally pour the boiled water Put into a teapot (make tea) for drinking.

The tea set with the above-mentioned traditional structure has the following deficiencies: (1) Due to the small size of the teapot, all the boiling water in the kettle cannot be poured into the teapot. A slight drop in temperature will affect the brewing of tea, and it cannot even be used as tea for drinking. Therefore, the excess boiling water in the kettle is often dumped, which wastes electricity; (2) Every time you make tea, you need to pour tap water into the kettle. Then place it on the surface of the induction cooker for heating, and finally pour boiling water into the teapot before you can make tea for drinking. On the other hand, it limits people's different choices of water sources.

For this reason, there are also some tea sets that use an instant electric heating device, that is, an instant heating device communicated with tap water or a water storage tank is set on the tea set, and an instant heating device communicated with the instant heating device is installed on the tea tray. faucet; when people make tea, put the teapot into the boiling faucet (this time "instant heating device"

power-on work), and then turn on the boiling water faucet, and the boiling water will flow out immediately until the teapot is filled with boiling water and then turn off the boiling water faucet. Cause waste and save electricity.

However, the above-mentioned tea-making set with an instant electric heating device still has the following disadvantages: (1) In view of the water storage tank (or balance water tank) on the tea tray, it only serves to store water (or balance level), When the instant heater encounters water shortage in the water storage tank, if it fails to stop (heat) in time, the instant heater is easily damaged due to dry burning; (2) the existing instant heating device, Electric heating plate or electric heating tube heating method is mostly used. This heating method has the disadvantages of low thermal efficiency and energy consumption; (3) Some tea trays also use metal pipeline heaters, and the water flow through the inner tube cavity of the metal pipeline heater is Instant heating, however, because the metal glass coated electric heating tube is easy to produce scale, resulting in poor taste of boiling water, which cannot meet the drinking needs of tea; moreover, the thermal expansion coefficient of the metallic glass coated electric heating tube is large, which is easy to cause bursting, therefore, Metallic glass-coated electric heating tubes have great potential safety hazards.
