a coffee machine

Abstract

The invention relates to a coffee machine which comprises a coffee machine body (10) used for producing hot water or hot steam for brewing coffee. A water tank (20) and a heating device (30) are arranged in the coffee machine body (10). The water tank (20) is connected with the heating device (30) through a cold water pipe (40). Hot water or hot steam heated by the heating device (30) flows out through a hot water pipe (50) which is arranged by being separated from the water tank (20). By means of the separated design of the hot water pipe and the water tank, the water temperature is prevented from being lowered as heat of the hot water in the hot water pipe is prevented from being absorbed by cold water in the water tank and the water temperature in brewing the coffee is endured. A water outlet of the water tank is designed to be concaved to prevent water from remaining in the bottom of the water tank and prevent the water tank from being polluted; a fixed flange is arranged on the water tank to enable the water tank to be installed and detached conveniently.

Description

technical field [0001] The invention relates to a coffee brewing device, in particular to a coffee machine. Background technique [0002] The traditional coffee brewing process requires several processes such as roasting, grinding, brewing, and filtering. Although the traditional coffee making process is very ornamental and interesting, brewing coffee in leisure time is also interesting, but Compared with the modern and fast life, many people do not have time to make coffee, so coffee machines have emerged as the times require. The working principle of the coffee machine is: add cold water into the water tank of the coffee machine, the water flows from the water tank into the heating device for heating, the heated water generates steam and bubbles, and under the action of pressure, the hot water is sprayed out through the shower and passes quickly. In the filter basket containing coffee grounds, there is an even resistance between the pressurized hot water and the coffee gr...

Problems solved by technology

[0003] When a traditional coffee machine is brewing coffee, the hot water generated by the heating device flows out from the hot water pipe passing through the inside of the water tank. The hot water pipe runs through the inside of the water tank and will contact the cold water inside the water tank. When the hot water flows through the hot water When the pipe is connected, the cold water outside will absorb heat, thereby reducing the water temperature in the hot water pipe and affecting the temperature of the hot water required for brewing coffee. The temperature of the hot water for brewing coffee is only about 80°C, which seriously affects the taste of coffee.

[0004] In addition, the water tank in the traditional coffee machine is made of plastic material. Water stored in the plastic water tank will produce plastic taste and affect the taste of coffee. Moreover, the plastic water tank will produce scale after long-term use, which is not easy to clean. ; What's more, the water outlet of the existing water tank is flush with the bottom. When the water flows to the heating device, a small part will remain at the bottom of the water tank. The remaining water will deteriorate and breed bacteria. The water tank needs to be cleaned, which brings inconvenience to use, and the existing water tank is inconvenient to disassemble and install
