Description
Technical field
The utility model relates to coffee machine, particularly relates to the desk-top coffee machine of a kind of indirect heating type.
Background technology
Very high (one glass of ESPRESSO coffee component 3,0 gram of standard of the production standard requirement of Italy's concentrated coffee (ESPRESSO), 22 seconds-28 seconds time, 86 ℃-88 ℃ of water temperatures), different seasons, environment, temperature, humidity are made all variant to Italian concentrated coffee, very high to density (thickness), the amount of tamping, the surface smoothness requirement of coffee powder when making coffee, amateur barista is to make the ESPRESSO coffee of one glass of standard.For adapting to the needs in market, the Espresso producer uses the equipment of specialty, and the special processing technology and the way of guaranteeing the quality are processed into the coffee cake with coffee powder, it is placed in the coffee cake machine, and barista that need not be professional also can punching out Italy concentrated coffee (ESPRESSO).It is convenient to make Italian concentrated coffee with coffee cake mechanism, quick, is suitable for business office, food and drink hotel, tourist attractions, leisure place and average family.Most important parts boiler is used the aluminum pot stove without exception in the desk-top coffee machine of Xiao Shouing in the market, its movement, adopts heating wire to cross water and heats and infuse coffee.Its weak point:
1. poor stability.In case the temperature controller of boiler formula heater is out of control or damage, boiler is easy to blast.
2. making the coffee quality of water can not get guaranteeing.The heating of boiler formula is that water is repeated heating, can cause water quality to change, unsuitable long-term drinking; Water in the boiler can't discharge, can the residual water that spends the night.
3. heating wire directly heats in water, can form incrustation scale on the electrothermal tube.
4. heating wire directly heats in water, and the oxygen molecule in the water is ionized son and destroys, as is used for punching out coffee, can directly influence healthy.
Summary of the invention
The purpose of this utility model is a kind of desk-top coffee machine of indirect heating type that can guarantee to make coffee water water quality of design.
In order to achieve the above object, the utility model adopts following technical solution: the desk-top coffee machine of a kind of indirect heating type, comprise heater, it is characterized in that heater is the indirect heating type heater, described indirect heating type heater comprises electrothermal tube, heat conduction copper body, spiral water flow grooves, spiral water pipe is located in the heat conduction copper body, electrothermal tube is located on the heat conduction copper body adjacent with spiral water flow grooves, and spiral water flow grooves import and export is connected with coffee machine water inlet, delivery port respectively.Because electrothermal tube heats water indirectly by the heat conduction of heat conduction copper body, thoroughly solved the hidden danger of boiler formula heating, avoid water in heating process, to produce electrolysis, guarantee the coffee quality of water, pure, the health requirement of the coffee mouthfeel that really reaches punching out.

The specific embodiment
As Fig. 1-shown in Figure 5, present embodiment comprises indirect heating type heater 1, described indirect heating type heater 1 comprises electrothermal tube 13, heat conduction copper body 14, spiral water pipe 7,12, spiral water flow grooves 7,12 is located in the heat conduction copper body 14, and electrothermal tube 13 is located on the heat conduction copper body 14 adjacent with spiral water flow grooves; Described spiral water flow grooves 7,12 by outer surface be provided with on the unidirectional installing hole that is contained in heat conduction copper body 14 of spiral fluted spiral copper rod 8 form, the outer end of spiral copper rod and installing hole are tightly connected 5.Be located at before helicla flute on the spiral copper rod outer surface comprises, the two sections helicla flutes 7 in back, 12, two helicla flutes 7,12 are separated by the water outlet cannelure 10 that is located on the spiral copper rod between adjacent, water outlet cannelure 10 is connected with rear screw groove 12, on the central axis of spiral copper rod end, be provided with axial passage 11, on the spiral copper rod at preceding helicla flute 7 tail end places, be provided with radial passage 9, axial passage 11 1 ends are connected with rear screw groove 12 ends, the other end is connected with radial passage 9, water outlet cannelure 10 is connected with coffee machine delivery port 15, be provided with the water inlet cannelure 6 that is connected with preceding helicla flute 7 at the neck place of spiral copper rod, water inlet cannelure 6 is connected with water inlet 16.
After the coffee water is come in from water inlet 16,, flow out, offer coffee brewing from coffee machine delivery port 15 through the spiral mobile heating of water inlet cannelure 6, preceding helicla flute 7, radial passage 9, axial passage 11, rear screw groove 12, water outlet cannelure 10.
Again as shown in Figure 2, coffee machine water inlet 16 is connected with return flow solenoid valve 4 (as shown in Figure 6), it can strengthen hydraulic pressure on the one hand, when calling it quits coffee,, keep the drying in the helical pipe on the other hand with surplus water backflow discharging in the helical pipe, a spot of coffee powder can be drawn in the helix tube simultaneously, be used for the space of bonding helix tube external diameter and heater hole inwall making coffee machine after making coffee, the external diameter of helix tube and heater inner hole wall just can fit like a glove.Naturally form complete spirality channel when therefore, current are by helical pipe in the heater.
In addition, for the temperature that makes heater remains at 95 ℃-98 ℃, on heat conduction copper body, be provided with temperature controller 2.When temperature was raised to 98 ℃, temperature controller 2 was cut off the electricity supply automatically, and when temperature dropped to 95 ℃, temperature controller 2 was connected power supply automatically, cut off the electricity supply so periodic duty when temperature is raised to 98 ℃ more automatically.Simultaneously, in order to prevent the temperature controller short circuit, be provided with temperature control short-circuit protector 3 on heat conduction copper body, after the temperature controller short circuit, the temperature of heater can rise always, and when temperature rose to 145 ℃, general supply was cut off in 3 work of temperature control short-circuit protector.Only after changing new temperature controller, hand-reset temperature-control protector, coffee machine recovers operate as normal again, plays the duplicate protection that is perfectly safe.
In sum, the utility model compared with prior art has the following advantages:
1, water temp. heating speed is fast, electric energy loss is low. Because the special construction of helical pipe is established Meter, the contact area of discharge and heater increases, and the water of normal temperature can be heated in moment 86 ℃-88 ℃, and take full advantage of heat energy, electric energy loss is dropped to least cost.
2, adopt duplicate protection, security is good.
