Description

Technical Field

[0001] The utility model relates to the technical field of heating components, and in particular to a heating pipe for internal and external heating. Background Art

[0002] At present, electric water heating devices are used more and more widely, such as kettles, electric water heaters, water dispensers and other household appliances. However, most of the electric water heating devices currently used adopt a single glass tube with a heating wire arranged inside the glass tube, and directly heat the water through the heating wire. This heating method makes the resistance heating wire directly contact with the water, which is easy to contaminate the water; and further, these heating wires have slow heating speed, low safety and uneven heat distribution.

[0003] In the existing technical solutions, such as the application number: 201520771564.5, a heating tube for internal and external heating includes a glass tube and end caps located at both ends of the glass tube, the two end caps are fixed by rubber rings and nuts, the end caps are provided with grooves adapted to the glass tube, the glass tube includes an inner tube and an outer tube, the inner tube and the outer tube are spaced apart to form a water flow channel, the two end caps are provided with water holes connected to the water flow channel, the outer surface of the outer tube is provided with a heating plate, the heating plate is arc-shaped and fits the outer wall of the outer tube, and the inner surface of the inner tube is provided with a nano-resistance heating film.

[0004] In the above scheme, the heating effect of the inside and outside of the tube is basically achieved through the cooperation of the heating plate and the water flow channel, as well as the setting of the nano-resistance heating film. However, the heat of the heating film comes from the high impedance generated when the resistor is energized. The resistor is an electrical component that is frequently energized and is easily damaged. Once the component is damaged, it may cause unstable heating of the inner tube. In addition, the heat conduction method of water flow has a low heat conduction efficiency. The inner tube will crack due to the problem of uniform heat, affecting its use. For this reason, it is necessary to improve the heat conduction component of the inner tube so that the heat of the inner and outer walls of the inner tube is more uniform. Utility Model Content

[0005] The utility model provides a heating tube for internal and external heating, which solves the problem of low heat conduction efficiency in a heating tube for internal and external heating in the related art.

[0012] There are multiple heating tubes, and the multiple heating tubes are distributed in an annular shape at the bottom of the disc rack. The outer wall surfaces of the multiple heating tubes are in gap contact with the inner wall surface of the inner tube.

[0013] A clamping groove is provided on the side wall surface of the heating component, and a temperature measuring component is movably clamped in the clamping groove.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 and 2 As shown, this embodiment lists relevant components for solving the problem of uneven heat conduction between the inner and outer walls of the inner tube.

[0027] In this embodiment, the inner tube 100 is provided, and a heat conducting member 400 is fixedly connected to the outer wall of the inner tube 100;

[0028] The heat conduction component 400 includes a boron nitride diaphragm 401, and aluminum oxide particles 402 are embedded and connected to the surface of the boron nitride diaphragm 401. A plurality of aluminum oxide particles 402 are provided, and the plurality of aluminum oxide particles 402 are annularly distributed on the surface of the boron nitride diaphragm 401. The outer wall surface of the boron nitride diaphragm 401 is in contact with the insulating outer tube 500.

[0029] Among them, the interlocking connection between the boron nitride diaphragm 410 and the aluminum oxide particles 402 makes the two become a composite thermal conductive material, which solves the problem of low heat conduction efficiency of water flow. The heat distribution on the inner and outer walls of the inner tube 100 is more uniform, and the damage and cracks caused by uneven heat are significantly improved. The boron nitride diaphragm 410 and the aluminum oxide particles 402 have the characteristics of isotropic heat dissipation, which avoids the heat absorption of the material itself. The hybrid interlocking structure of ball and sheet has faster thermal response performance and significantly improves the heat conduction efficiency.

[0030] The top of the inner tube 100 is provided with a supporting member 300 , which includes a disc frame 301 fixed to the top of the inner tube 100 , a pillar 302 is fixedly connected to the inner upper surface of the disc frame 301 , and a top cover 204 is plugged into the top of the pillar 302 .

[0031] The inner tube 100 is provided with a supporting member 300 so that the top of the inner tube 100 is well supported. The plug-in connection between the disc frame 301 and the pillar 302 and the top cover 204 can provide a supporting platform for the subsequent temperature measuring component 205.

[0032] Example 2

[0033] like Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes relevant components for heating the inner tube.

[0034] In this embodiment, the heating component 200 where the top cover 204 is located also includes a three-way plug 203, the bottom of the three-way plug 203 is fixedly connected to the top of the top cover 204, and the bottom of the three-way plug 203 is electrically connected to the heating tube 201 through a cable, the top of the heating tube 201 is fixedly connected to the rubber ring 202, and the disc frame 301 is provided with a through hole, the inner wall surface of the through hole is connected to the outer wall surface of the heating tube 201, a straight shaft 304 is inserted into the bottom of the heating tube 210, and a sealing cover 303 is fixed to the bottom of the straight shaft 304, and the inner wall groove of the sealing cover 303 is movably connected to the bottom of the insulating outer tube 500.

[0035] Among them, the three-way plug 203 is connected to the heating tube 201 through a cable, so that the three-way plug 203 can supply power to the heating tube 201 in time after being connected to the mains power. The fixed connection between the rubber ring 202 and the heating tube 201 makes it more convenient to replace and repair the heating tube 201 when it needs to be replaced, effectively reducing the risk of burns. The through connection between the disc frame 301 and the heating tube 201 can provide support and protection for the heating tube 201, and the clamping connection between the cover 303 and the insulating outer tube 500 is conducive to the stable support of the insulating outer tube 500.

[0036] There are multiple heating tubes 201 , and the multiple heating tubes 201 are distributed in an annular manner at the bottom of the disc rack 301 . The outer walls of the multiple heating tubes 201 are in gap contact with the inner wall of the inner tube 100 .

[0037] The annular arrangement of the heating tube 201 enables the inner tube 100 to obtain more sufficient heat, thereby ensuring the supply of heat source during the heat conduction process.

[0038] Example 3

[0039] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes relevant components for supporting and protecting the outer wall of the inner tube.

[0040] A slot is formed on the side wall of the heating component 200 , and the temperature measuring element 205 is movably engaged in the slot.

[0041] The temperature measuring element 205 is connected to the heating component 200 through the card slot, so that the heating component 200 can monitor the temperature of the inner tube 100 in time after heating, and further cut off the power or continue to supply power for heating in time according to the temperature situation.

[0042] A through hole is provided at the center of the top cover 204 , and the center of the through hole coincides with the center of the inner tube 100 . The insulating outer tube 500 is made of ceramic, and the outer wall of the insulating outer tube 500 is provided with anti-slip stripes.

[0043] The flow hole of the top cover 204 coincides with the center of the inner tube 100, so that some heat can escape and dissipate, avoiding excessive air pressure inside the inner tube 100, and improving the safe use of the inner tube 100. The anti-slip stripes set on the insulating outer tube 500 are conducive to the grip of the entire component, allowing the component to be used in more occasions.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
