AI Technical Summary

Technical Problem

Traditional coffee machine water tanks lack a constant temperature design, resulting in large temperature fluctuations and slow heating, which cannot meet the needs of quick coffee making and also causes uneven heating, affecting coffee quality.

Method used

A constant temperature water tank for a coffee machine was designed, which adopts a split-chamber structure, a spiral electric heating rod and heat-conducting fins, combined with a temperature sensor and an electronic relay to achieve automatic adjustment and uniform heating of water temperature, and an external heat insulation coating to maintain stable water temperature.

Benefits of technology

It achieves stable water temperature and uniform heating, ensuring a constant water temperature, improving the taste and quality of coffee, and meeting the need for quick coffee making.

Abstract

This utility model discloses a constant temperature water tank for a coffee machine, including a tank body and a cover. The tank body is divided into a water inlet section and a heating section. The water inlet section includes an outer casing and an inner casing, with a water filling chamber between the outer casing and the inner casing. A first drain hole is opened on the bottom surface of the water filling chamber, and a second drain hole is opened on the wall of the inner casing. An electric heating rod is installed on the inner bottom surface of the heating section, and an electric heating element is installed on the inner side wall of the heating section. A water inlet pipe is connected to the casing of the water inlet section, and a water outlet pipe is connected to the bottom casing of the heating section. A liquid level sensor is installed on the inner bottom surface of the tank body. In this utility model, cold water slowly flows into the water tank through the drain hole in the water filling chamber. Due to the slow flow rate, heat exchange with the hot water in the tank can be completed slowly and fully, thereby keeping the overall water temperature in the tank basically balanced and avoiding excessive fluctuations in the water temperature, thus ensuring a constant water temperature.
