Description

Instant heating device and tea drinking machine

Technical Field

The utility model relates to the technical field of household appliances, in particular to an instant heating device and a tea drinking machine.

Background

The instant heating device is popular in the market because the temperature rise speed is high, and drinking water can be heated to the target temperature within 3 seconds or even within 1 second, so that the instant heating device is widely applied to electric heating drinking water machines, such as water dispensers, coffee machines and the like. The instant heating device mainly comprises a heating pipe, a sealing structure, a temperature measuring component and the like, wherein a part for realizing rapid heating is the heating pipe, and the heating pipe can be made of conductive materials such as stainless steel or a nano-coated quartz tube. The heating principle is as follows: the heating pipe is electrified and heated to enable the temperature of the heating pipe to be higher than the target temperature of the water flow, and the heated heating pipe conducts heat to the water flow flowing through the pipeline, so that the water flow is rapidly heated.

Compared with the traditional boiler type heating device, the instant heating device has higher heating speed and reduces the waiting time of a user when heating water. However, the disadvantages are that high temperature cannot be achieved and temperature control is unstable, and the reasons are two main reasons: 1. the heating principle is that the water flow passing through the water heater is subjected to instantaneous heat transfer, the time is short, the heat storage process is avoided, and heat accumulation cannot be formed; 2. because the water flows through the water flow bundle rapidly, the center of the water flow bundle can not be heated sufficiently, and the temperature of the water flow bundle is lower than the peripheral temperature, so that the water outlet temperature of the whole water flow bundle is low after heating, and the water outlet temperature is not uniform.

As is known, the temperature is particularly important for extracting tea, and particularly for tea needing baking such as clovershrub, strong-fragrance Tieguanyin tea and the like, the brewing temperature is required to be more than 95 ℃ so as to extract the tea fragrance which is high in popularity. For the tea drinking machine, the outlet water temperature of the instant heating device is required to be higher than 98 ℃ in consideration of the heat loss of 2-3 ℃ in the delivery process of making tea by leading water to reach tea capsules through a water channel pipeline. The highest actual measurement temperature of the existing instant heating device is below 97 ℃, the highest water temperature is only 95 ℃ when the water reaches the interior of the capsule through the water pipeline for brewing, and the brewed tea soup is not fragrant. Therefore, although the instant heating device is widely applied to a water dispenser and a coffee machine, the instant heating device is rarely applied to a tea dispenser, particularly a capsule tea dispenser.
