Abstract
The utility model discloses a coffee machine, including beverage box and water tank, beverage box and water tank are linked together through water pipeline, water pipeline stretches into the bottom of water tank, characteristics are that the top of water tank is provided with the pressure release hole, relief valve and take sealing device's filler, the bottom downwardly extending of water tank is provided with the U-shaped heating pipe, vertically be provided with the water pipe in the water tank, the end of intaking of U-shaped heating pipe is linked together and its delivery end and water pipe are linked together with the water tank, the end of intaking of U-shaped heating pipe is provided with the check valve that control flow got into U type heating pipe by the water tank, the diameter in pressure release hole is less than 1mm, the pressure release pressure of relief valve is less than 0.5bar, the advantage is with low costs, effective control goes.
Description
Technical Field
The utility model relates to a beverage equipment field especially relates to a coffee machine.
Background
Many low-pressure coffee machines on the market basically use an electromagnetic pump and a straight-flow pump to provide pressure, which results in high cost.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a coffee machine with low cost and effectively controlled water outlet pressure.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a coffee machine, includes beverage box and water tank, the beverage box with the water tank be linked together through water pipeline, water pipeline stretch into the bottom of water tank, the top of water tank be provided with pressure release hole, relief valve and take sealing device's filler, the bottom downwardly extending of water tank be provided with the U-shaped heating pipe, the water tank in vertically be provided with the water pipe, the water inlet end of U-shaped heating pipe with the water tank be linked together and its water outlet end with the water pipe be linked together, the water inlet end of U-shaped heating pipe be provided with control rivers by the water tank get into the check valve of U-shaped heating pipe.
The diameter of the pressure relief hole is smaller than 1 mm.
The pressure relief pressure of the pressure relief valve is less than 0.5 bar.
The sealing device is a rubber sealing plug or a sealing cover.
The pressure relief hole is positioned on the sealing cover.
The water outlet of the upper water pipe is higher than the liquid level in the water tank.
Compared with the prior art, the utility model has the advantages of: the utility model relates to a coffee machine, after adding water into the water tank from the position of adding water, seal the position of adding water, when the heating tube is working, the water in the water tank enters U-shaped heating tube through the check valve, after the heating tube is heated, the hot water returns to the water tank through the water supply pipe under the action of steam pressure, the water is heated circularly until the pressure in the water tank is greater than the pressure of relief valve and water path + beverage box, then the water begins to flow out to the beverage box from the water path; the arranged pressure relief hole not only plays a role in pressure relief, but also keeps the water tank in an incomplete sealing state, so that the problem that water is difficult to add from a water adding position to enter the water tank because vacuum is formed in the water tank is avoided; when the pressure of the water tank is greater than the pressure of the pressure release valve, the pressure release valve opens to release the pressure, the pressure of the water tank is ensured not to be too large to cause the beverage box to break, and the coffee machine has the advantages of low cost and effective control of water outlet pressure.
