Abstract

The coffee machine of family expenses Optical wave electric heating tube heating, on the boiler (14) of coffee machine, welding or mechanical connection manner install 1 metal or nonmetallic hollow pipe (17), and ensure that container is sealed；Metal or nonmetallic hollow pipe (17) are the straight pipes that two ends are externally opened wide, or open at one end, the blind hole pipe that one end is closed in boiler；The heater block filled in it is used after Optical wave electric heating tube, i.e. energization work, and electrothermal tube had both produced heat energy or produced infrared light.

Description

The coffee machine of family expenses Optical wave electric heating tube heating

Technical field

The present invention relates to domestic coffee maker.

Background technology

Be currently used for the electrothermal tube in coffee machine, be by shell of metal tube, heating alloy make heater, Closely knit magnesium oxide powder dielectric is loaded in metal tube, to fix the element of heater；This metal shell Electric heating element, is completely sunk in the water, after long-time use, meeting scaling, particularly 60 DEG C high in production ＞ When warm water and steam, more can scaling reduction heating efficiency, and corrosion puncture, make water powered.

The content of the invention

The purpose of the present invention is that existing domestic coffee maker is improved.

The technical measures of the present invention are that on the boiler 14 of domestic coffee maker, welding or mechanical connection manner are installed 1 nonmetallic hollow pipe 17, and ensure that container is sealed；Metal or nonmetallic hollow pipe 17 are that two ends are externally opened The straight pipe opened, or open at one end, the blind hole pipe that one end is closed in boiler；The heater block filled in it After Optical wave electric heating tube, i.e. energization work, electrothermal tube had both produced heat energy or had produced infrared light, and realization adds to water Heat, to produce hot water and steam；Electrothermal tube 16 has several forms：

1. electrothermal tube such as Fig. 1 that dress heating wire is constituted in the air in straight-through or blind hole non-metallic pipe extremely schemes Shown in 2；

2. the electrothermal tube of heating wire and metal tube insulation is such as schemed in metal tube built-in heating wire magnesium oxide powder 3rd, shown in Fig. 4；

3. general non-metal electric heating pipe, including carbon fiber pipe are directly filled in metal or nonmetallic hollow pipe 17 Or halogen electrothermal tube is as shown in Figure 5, Figure 6；

Heated the beneficial effects of the invention are as follows coffee machine using Optical wave electric heating tube, not scaling, the thermal efficiency is high.

Brief description of the drawings

Fig. 1 is existing domestic coffee maker outline drawing；

Fig. 2 is the structure principle chart of domestic coffee maker；

Fig. 3, Fig. 4, Fig. 5 are the sectional views of coffee machine boiler after improving；

Fig. 6 to Figure 12 is with the non-metal shell electrothermal tube schematic diagram used in domestic coffee maker boiler；

Embodiment

In accompanying drawing, steam/heat water valve 1, operational and controlled key button 2, brew handle 3, tank lid 4, water tank 5, steam Steam pipe 6, pump 8, brewing shower nozzle 10, coffee cup 11, water accumulating disc 12, filter 13, boiler 14, electric heating Pipe 16 (eduction rod 16-1, heating wire 16-3, magnesia powder or air 16-4, metal tube 16-5, non-gold Belong to plug or mounting seat 16-6, straight-through non-metallic pipe 16-7 blind hole non-metallic pipes 16-8, insulant 16-9, Carbon fiber pipe or halide torch or dry combustion method electrothermal tube 16-10), metal or nonmetallic hollow pipe 17 (including straight pipe Or blind hole pipe).

Fig. 1 is the outline drawing of domestic coffee maker, and Fig. 2 is boiler 14 in domestic coffee maker structure principle chart, figure It is the sealing container for producing hot water and steam, 1 metal hollow pipe of welding in boiler 14, or in boiler Straight-through metal or nonmetallic hollow pipe are mechanically installed.

Fig. 6 to Figure 12 is can be with optional electrothermal tube in 2, and wherein Figure 10 to Figure 12 is in straight-through or blind hole The electrothermal tube that heating wire is constituted is filled in air in non-metallic pipe；Fig. 6, Fig. 7 are in metal tube 16-5 Heating wire 16-3 is filled, the electrothermal tube for heating wire and metal tube isolated insulation being constituted with magnesia powder, Fig. 8 It is that carbon fiber pipe or halogen electrothermal tube are directly included using non-metal electric heating pipe with Fig. 9.

Above-mentioned electrothermal tube is arranged in metal or nonmetallic hollow pipe 17, and the water in boiler need not be vented during replacing And steam.
