Abstract

The utility model discloses a coffee machine, which comprises a water storage tank, a high-temperature heating element, a base, a coffee bottle, a handle, a filter, a water flow distribution plate, a heating box, and a vacuuming device. The vacuuming device includes a vacuuming machine, a first Solenoid valve, the second solenoid valve, the advantage, because the vacuum device is installed on the coffee machine, we can close the second solenoid valve when heating water, open the first solenoid valve, and pump the inside of the heating box into a vacuum environment. Pumping the heating box into a vacuum environment actually reduces the air pressure in the heating box. When the air pressure in the heating box becomes smaller, the boiling point of the water will also decrease, so that the temperature of the water for brewing coffee will not change when it boils. It will be too high. When the water boils, close the first electromagnetic valve and open the second electromagnetic valve to extract the water to brew coffee. The taste of the brewed coffee is particularly good, and the device is simple and convenient to operate.

Description

a coffee machine

technical field

The utility model belongs to the field of coffee machines, in particular to a coffee machine.

Background technique

With the improvement of living standards and the increasing number of people drinking coffee, coffee machines have entered thousands of households and are purchased and used by people as common household appliances. The brewing of powder is also one of the important factors affecting the taste of coffee. Existing coffee machine nozzles spray hot water on the coffee powder to fuse the hot water with the coffee powder, but the existing coffee machine usually heats the water too high, as people who drink coffee for a long time know, In fact, the temperature of the water for brewing coffee should not be too high. If the temperature is too high, it will affect the taste of the brewed coffee. If the temperature is not high, the water cannot boil, and a large amount of water vapor cannot be produced, which will also affect the taste of coffee.

Utility model content

Aiming at the above-mentioned problems in the prior art, the utility model provides a coffee machine.

Its technical solution is:

A coffee machine, comprising a water storage tank, a high-temperature heating element, a base, a coffee bottle, a handle, a filter, a water flow distribution plate and a heating box, the heating box is arranged under the water storage tank, the high-temperature heating element is installed inside the heating box, and the filter A water flow distribution plate is installed on the filter, a coffee bottle is arranged under the coffee bottle, a base is arranged under the coffee bottle, the water storage tank is connected to the heating box through a pipeline, and the heating box is connected to the water flow distribution plate through a pipeline. It is characterized in that the coffee machine also has A vacuum device is provided, and the vacuum device includes a vacuum machine, a first electromagnetic valve, a second electromagnetic valve, a vacuum tube, and a water suction tube. The vacuum tube is connected to the top of the heating box, and the water suction tube is connected to the bottom of the heating box. The first The solenoid valve is arranged on the vacuum pipe, and the second solenoid valve is arranged on the water pipe.

Because a vacuum device is installed on the coffee machine, the second electromagnetic valve can be closed when the water is heated, and the first electromagnetic valve can be opened to reduce the pressure in the heating box. When the air pressure in the heating box becomes smaller, the boiling point of the water also decreases. It is reduced, so that the temperature of the water for making coffee will not be too high when it boils. When the water boils, close the first solenoid valve and open the second solenoid valve to pump the water out to brew coffee. The taste of the coffee coming out is particularly good, and the device is easy and convenient to operate.
