Utility model content
The purpose of this utility model is to provide a kind of coffee machine boiler, has advantages of that heat hydraulic pressure is higher, it is little to take up room and heat efficiency is high.
To achieve these goals, the technical solution adopted in the utility model is as follows: coffee machine boiler, comprise the upper cover, pot body and the lower cover that are fixed together successively, also comprise the water inlet pipe and the outlet pipe that are connected with pot body, and be positioned at pot body electrothermal tube, it is characterized in that, described upper cover, pot body and lower cover are made by stainless steel material and pass through laser weld together; Power connection end of described water inlet pipe, outlet pipe and electrothermal tube is all fixedly installed on described and covers, and the water side of described water inlet pipe is positioned at the hot zone of described electrothermal tube.
Preferably, the terminal of described water inlet pipe, outlet pipe and electrothermal tube is all fixedly installed on described and is covered by laser weld.
Preferably, the hot zone of described electrothermal tube is helix tube, in the water side of described water inlet pipe is enclosed in by described helix tube.
Preferably, the helix tube center line of described electrothermal tube overlaps with the center line of described pot body.
Preferably, the water side of described water inlet pipe is positioned at the centerline of described helix tube.
Preferably, also comprise by laser weld in the upper NTC joint covering.
Preferably, also comprise the ground terminal on power connection end that is connected in electrothermal tube.
Coffee machine boiler of the present utility model, upper cover, pot body and lower cover all adopt stainless steel material to make, and adopt laser weld mode to make them form an overall structure simultaneously, can bear compared with large pressure and holding structure stability; Electrothermal tube heats in stainless steel pot body, make water be subject to thermosetting convection current, avoid water to be heated inhomogeneous, thermal efficiency uses the unfavorable factors such as insufficient, when water is heated to after uniform temperature, by the pressure in pot body, hot water is discharged from outlet pipe, can form the hot water with hydraulic pressure, meet the requirement of infusing coffee; In addition, by water inlet pipe and outlet pipe are all fixedly mounted on and are covered, make to complete by this one end of upper cover into water and water outlet, can save large quantity space in coffee machine, be easy to installation and the use of coffee machine.Therefore, coffee machine boiler of the present utility model, has advantages of that heat hydraulic pressure is higher, it is little to take up room and heat efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As depicted in figs. 1 and 2, the utility model is a kind of coffee machine boiler, comprise the upper cover 10, pot body 20 and the lower cover 30 that are fixed together successively, also comprise the water inlet pipe 11 and the outlet pipe 12 that are connected with pot body 20, and being positioned at the electrothermal tube 13 of pot body 20, described upper cover 10, pot body 20 and lower cover 30 are made by stainless steel material and pass through laser weld together; Power connection end of described water inlet pipe 11, outlet pipe 12 and electrothermal tube 13 is all fixedly installed on described upper cover 10, and the water side of described water inlet pipe 11 is positioned at the hot zone of described electrothermal tube 13.Coffee machine boiler of the present utility model, upper cover 10, pot body 20 and lower cover 30 all adopt stainless steel material to make, and adopt laser weld mode to make them form an overall structure simultaneously, can bear compared with large pressure and holding structure stability; Electrothermal tube 13 is in the interior heating of stainless steel pot body 20, make water be subject to thermosetting convection current, avoid water to be heated inhomogeneous, thermal efficiency uses the unfavorable factors such as insufficient, when water is heated to after uniform temperature, by the pressure in pot body 20, hot water is discharged from outlet pipe 12, can form the hot water with hydraulic pressure, meet the requirement of infusing coffee; In addition, by water inlet pipe 11 and outlet pipe 12 are all fixedly mounted on upper cover 10, make to complete by upper cover 10 these one end into water and water outlet, can save large quantity space in coffee machine, be easy to installation and the use of coffee machine.Therefore, coffee machine boiler of the present utility model, has advantages of that heat hydraulic pressure is higher, it is little to take up room and heat efficiency is high.
In order further to promote the sealing of boiler and the pressure that boiler can bear, the terminal of described water inlet pipe 11, outlet pipe 12 and electrothermal tube 13 is all fixedly installed on described upper cover 10 by laser weld.
In addition, in order to improve the heat efficiency of electrothermal tube 13, water is uniformly heated, the hot zone of described electrothermal tube 13 is helix tube 14, in the water side of described water inlet pipe 11 is enclosed in by described helix tube 14, further, helix tube 14 center lines of described electrothermal tube 13 overlap with the center line of described pot body 20, and the water side of described water inlet pipe 11 is positioned at the centerline of described helix tube 14 simultaneously.Add the water side of the water inlet pipe 11 of cold water to be positioned at helix tube 14 center, helix tube 14 is positioned at pot Shen20 center, makes the homogeneous heating of electrothermal tube 13 to cold water, and the utilization rate of heat efficiency greatly improves.
In order to improve the safety coefficient of use, boiler also comprises the NTC joint 15 on upper cover 10 by laser weld, is responded to the water temperature of pot in body 20 and controlled the state of electrothermal tube 13, water inlet pipe 11 or outlet pipe 12 by temperature-sensitive device.In addition, boiler can also comprise the ground terminal 16 on power connection end that is connected in electrothermal tube 13, to promote Electrical Safety.
