Abstract
A heating device of a coffee machine comprises a heater, a heating water pipe and a temperature controller, wherein the cross section of the heating water pipe is polygonal. As the circular internal-diameter cross section of the heating water pipe of a traditional coffee machine is modified to be starlike polygonal, the contact area between water in the heating water pipe and the pipe wall is increased, and accordingly, the heating efficiency of the coffee machine is improved; and besides, a stainless-steel spring is arranged in the heating water pipe, so that the heating efficiency of the coffee machine is further improved. Under the premise of not increasing the heating power of the coffee machine, the water outlet temperature of the coffee machine is improved through increasing the contact area between water and the pipe wall and additionally arranging the spring in the heating water pipe.
Description
Technical field
The utility model relates to a kind of heater of coffee machine.
Background technology
Along with growth in the living standard, increasing people bring into use coffee machine to make coffee.Existing coffee machine generally has Feedwater Heater, especially for water clock formula coffee machine, and the Feedwater Heater device that more is absolutely necessary.But the heating pipe of the Feedwater Heater of common water clock formula coffee machine is formed by common aluminum profile extrusion, and the internal diameter of aluminium is circular; And internal diameter is that circular heating pipe is when heating, because the contact area of tube wall and water is little, so its heat-transfer effect is poor, leaving water temperature is low.Chinese patent literature CN202051550 comprises heat-generating pipe and water pipe in the hot-water heating system that on November 30th, 2011 disclosed a kind of coffee machine, and water pipe has two, a left side that is arranged on heat-generating pipe, and another root is arranged on the right of heat-generating pipe.It is said that the hot-water heating system of this coffee machine can be realized the post bake of cold water by two water pipes, thereby improve the leaving water temperature of coffee machine.But the cross section of this utility model heating pipe internal diameter remains traditional circle, and the contact area of water and tube wall is less.Therefore, said structure is necessary to do further improvement.
The utility model content
The purpose of this utility model aims to provide a kind of firing rate that can improve the coffee machine drinking water, improves the heat transfer effect of heater, and the heater of the coffee machine of energy savings is to overcome the deficiencies in the prior art part.
Press the heater of a kind of coffee machine of this purpose design, comprise heater, heating pipe and temperature controller, its architectural feature is that the cross section of heating pipe's internal diameter is starlike polygon.
Described heating pipe's a end is intake tunnel, and the other end is exhalant canal, and the internal diameter cross section of intake tunnel and exhalant canal all is starlike polygon, and intake tunnel all is connected with the diversion flexible pipe with exhalant canal.
Be provided with spring in the described heating pipe, spring contacts to projecting inward interior angle with the heating pipe.
Described heater is arranged in the heater tube of heating pipe below, and heater tube and heating pipe are formed in one.
Described temperature controller is fixed on heater tube and the heating pipe by geometrical clamp, and an end of temperature controller is connected with temperature fuse, and the other end is connected with the control power supply.
Described temperature fuse is more than one, and a plurality of temperature fuses are connected in series, and the one end is connected with the cold pin of heater.
Described heating pipe and heater tube are aluminum pipe, and spring is stainless steel spring.
The utility model is improved to starlike polygon with the heating pipe's of conventional coffee machine internal diameter cross section by circle, has increased the contact area of heating pipe's tube wall and water with this, thereby has improved the efficiency of heating surface of coffee machine; In addition, this coffee machine also is provided with a stainless steel spring in the heating pipe, with the efficiency of heating surface of further raising coffee machine.The utility model the contact area by increasing water and tube wall, is set up spring in the heating pipe under the prerequisite that does not increase the coffee machine heating power, improved the leaving water temperature of coffee machine.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Fig. 2 is that the broken section of an embodiment sends out figure big.
Among the figure: 1 heating pipe, 1.1 is cross section, and 1.2 is intake tunnel, and 1.3 is exhalant canal, and 2 is heater tube, and 2.1 is heater, and 3 is temperature controller, and 4 is geometrical clamp, and 5 is spring, and 6 is temperature fuse.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of heater of coffee machine comprises heater 2.1, heating pipe 1 and temperature controller 3.Heating pipe 1 is aluminum pipe, and the cross section 1.1 of aluminum pipe internal diameter is starlike polygon.End at aluminum pipe is intake tunnel 1.2, and the other end is exhalant canal 1.3, and the cross section 1.1 of intake tunnel and exhalant canal internal diameter all is starlike polygon, and all is connected with the diversion flexible pipe.Be provided with stainless steel spring 5 in intake tunnel 1.2 and exhalant canal 1.3, spring contacts to projecting inward interior angle with heating pipe 1.Heater 2.1 is arranged in the heater tube 2 of heating pipe 1 below, and heater tube is the aluminum pipe that is formed in one with heating pipe 1.Temperature controller 3 is fixed on heater tube 2 and the heating pipe 1 by geometrical clamp 4, and an end of temperature controller 3 is connected with the temperature fuse 6 of 2 series connection, and the other end is connected with the control power supply.One end of temperature fuse is connected with the cold pin of heater 2.1.
In use, because the cross section 1.1 of aluminum pipe internal diameter is starlike polygon, compare for circular heating tube with traditional internal diameter cross section, it has increased the contact area of tube wall and water, thereby has improved the efficiency of heating surface of coffee machine; And be arranged on stainless steel spring 5 in intake tunnel 1.2 and the exhalant canal 1.3, because its good heat-conducting has further improved the efficiency of heating surface of coffee machine to drinking water.Simultaneously, the current in 3 couples of heating pipes of temperature controller 1 carry out indirect temperature control, in case after the water in the heating pipe 1 was heated to preset temperature, temperature controller 3 automatic disconnections were connected with power supply, heater 2.1 stops heating.If temperature controller 3 lost efficacy, heater 2.1 still continues heating, and then when heating pipe 1 temperature had reached the specified fusing-off temperature of temperature fuse 6, temperature fuse 6 is fusing automatically, with the protection heater circuit.
The utility model the contact area by increasing water and tube wall, is set up spring 5 in heating pipe 1 under the prerequisite that does not increase the coffee machine heating power, improved the leaving water temperature of coffee machine.
