Problems solved by technology
The common feature of these two steam generators is that a water pump is required to supply water, that is, a certain water pressure must be provided; hot water and steam share the same heating channel, and then the channels for hot water and steam are separated by complex conversion devices. Separate, so its structure is more complicated, the processing and production procedures are more cumbersome, and the price is more expensive

Embodiment Construction
[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] see Figure 1-Figure 7 , the casing of the steam generator is composed of an upper cover 1, a middle cover 2 and a lower cover 3 in turn. The upper cover 1 is provided with a U-shaped opening groove 11, and the grooves 11 are respectively embedded with U-shaped water pipes 4 and 3. U-shaped heating element 5, the heating element 5 is attached to the middle cover 2, the part where the middle cover 2 and the heating element 5 are attached is a plane, and the other side of the middle cover 2 is provided with an elongated ring-shaped water tank 21. The shape of the groove 11 , the water pipe 4 and the heating body 5 can also be made into a V-shaped, ω-shaped or Ω-shaped.
[0027] A sealing ring 8 for preventing leakage of high-pressure steam is also provided between the lower cover 3 and the middle cover 2; the lower cover 3 is connected with the annu...

The invention relates to a steam generator and its manufacturing method, which includes a water pipe arranged in the shell, water groove and heating body, the shell is made up of an upper cover, middle cover and subjacent cover, there arranges with a water pipe and heater between the upper cover and the middle cover, the heater is connected to the back surface of the water groove, the subjacent cover is arranged with a temperature controller and drainage valve. The upper cover is arranged with an aperture concave slot, the slot is embedded with water pipe and heater, the heater is attached with the middle cover, another surface of the middle cover is arranged with a thin ring type water groove. There has a sealing ring between the upper cover and the middle cover. The three covers are connected with bolt. The invention is simple, needs no pump, and the channels of hot water and steam are independent, the branching system can be saved out, the process is simple, the cost is low, safe and convenient.
Description
technical field [0001] The invention relates to a steam generator used in a coffee machine, which can generate both hot water and steam, and a manufacturing method thereof. Background technique [0002] Existing steam generators can be roughly divided into two types: boiler-type steam generators and trickle-flow steam generators. The boiler-type steam generator includes a large heating vessel, a heating tube, a water outlet channel, and a steam channel. The water enters the heating vessel from the water inlet hole on the heating vessel. After the water is heated to boiling and vaporized into water vapor, the heating The water outlet channel or steam channel at the top of the container discharges. The trickle-flow steam generator mainly includes a heater, a heating tube, and a shunt system. The heating tube is installed in the heater, and a slender water tank is arranged inside the heater. The water enters the slender water tank from the water inlet, and when it flows throug...
