Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a main body structure of a steam humidifier with efficient heating. Background Art

[0002] With the continuous improvement of people's living quality, the requirements for the living environment are also getting higher and higher. Among them, the indoor air humidity is one of the important factors affecting the living comfort. When the indoor air is too dry, it will not only have an adverse impact on human health, but also may cause damage to furniture, electronic devices, etc. Therefore, it has become increasingly common to use humidifiers to adjust the indoor humidity. Existing humidifiers usually adopt two working principles: ultrasonic type or evaporation type. The evaporation type humidifier is favored by users because it has no ultrasonic oscillation components and thus produces less noise during operation.

[0003] Traditional steam humidifiers on the market usually use electric heating wires or die-cast heating elements for heating. However, heating by these methods often has high energy consumption, long heating-up time, and it is difficult to clean due to the gaps between the electric heating wires; for die-cast heating elements, the surface may not be smooth enough, especially after long-term use, there may be micro-cracks or depressions on the surface. These uneven surfaces are prone to accumulating impurities and are also difficult to clean thoroughly.

[0004] The present utility model is made based on the above situation. Content of the Utility Model

The steam pipe divides the inner cavity of the water tank body into a water storage cavity and a heating cavity. The water storage cavity is arranged outside the steam pipe, and the heating cavity is arranged inside the steam pipe.

[0016] An efficient heating steam humidifier main body structure as described above, the size of the graphene heating element is less than or equal to the bottom size of the steam pipe.

[0017] Compared with the prior art, the present utility model has the following advantages:

[0018] 1. In this case, heating is carried out by a graphene heating element. The graphene heating element has a very high electron mobility. It can pass an electric current with a very low resistance. Since the resistance is small, the energy dissipated in the form of heat is relatively small. Therefore, electrical energy can be converted into heat energy more efficiently; the graphene heating element can achieve uniform distribution of the surface temperature, avoiding the local overheating problem that may exist in traditional heating materials, which helps to improve the thermal efficiency and reduce energy waste; the graphene heating element has a very high thermal conductivity, and its heating and cooling speeds are very fast, and the temperature can be quickly adjusted according to needs, thus saving energy.

[0019] 2. The graphene heating element is arranged on the outer side of the bottom of the water tank and does not directly contact the water, so there will be no scale adhesion during heating; the surface of the graphene heating element is usually very smooth, which makes it not easy to adsorb dust or other impurities; graphene has good chemical stability and is not easy to react with other substances under normal use conditions, so it is not easy to form compounds that are difficult to remove. Therefore, the graphene heating element is easier to clean. Of course, a water flow channel can also be opened at the bottom of the water tank so that water can flow onto the graphene heating element, and the heat can directly act on the water without being blocked by the water tank, thereby having a better heat transfer rate and better energy utilization rate.

[0020] 3. A first heat insulation cavity is arranged inside the pipe wall of the straight pipe section, and a second heat insulation cavity is arranged inside the pipe wall of the arc-shaped cover section. The first heat insulation cavity and the second heat insulation cavity form a heat insulation cavity, which can reduce the heat transfer to the water in the water storage cavity, thereby reducing heat energy loss and improving energy utilization rate.

[0021] 4. The second heat insulation cavity gradually increases from top to bottom along the extension direction of the arc-shaped cover section, that is, the closer to the graphene heating element, the larger the second heat insulation cavity. Generally speaking, the temperature closer to the graphene heating element will be higher. The larger second heat insulation cavity can more effectively reduce the heat transfer from the steam conduit to the water storage cavity, can further improve the heat insulation effect, and better reduce heat loss.

[0028] The following further describes the present invention in conjunction with the drawings:

[0029] As Figures 1 to 5An efficient heating steam humidifier main body structure is shown, including a water tank body 1. A steam pipe 2 is penetrated in the water tank body 1. The steam pipe 2 divides the inner cavity of the water tank body 1 into a water storage cavity 11 and a heating cavity 12. The water storage cavity 11 is arranged outside the steam pipe 2, and the heating cavity 12 is arranged inside the steam pipe 2. The water in the water storage cavity 11 seeps into the heating cavity 12 from between the bottom of the steam pipe 2 and the bottom of the water tank body 1. A heat insulation board 8 is arranged at the bottom of the water tank body 1. A graphene heating element 3 and an installation structure for installing the graphene heating element 3 are arranged between the heat insulation board 8 and the bottom of the water tank body 1. The graphene heating element 3 is located below the heating cavity 12.

[0030] In this case, heating is carried out by the graphene heating element 3. The graphene heating element 3 has a very high electron mobility. It can pass an electric current with a very low resistance. Since the resistance is small, the energy dissipated in the form of heat is relatively less. Therefore, it can convert electrical energy into heat more efficiently; the graphene heating element 3 can achieve a uniform distribution of the surface temperature, avoiding the local overheating problem that may exist in traditional heating materials, which helps to improve the thermal efficiency and reduce energy waste; the graphene heating element 3 has a very high thermal conductivity, and its heating and cooling speeds are very fast, and the temperature can be quickly adjusted according to needs, thus saving energy.

[0031] The graphene heating element 3 is arranged on the outer side of the bottom of the water tank body 1 and does not directly contact the water, so there will be no attachment of water scale during heating; the surface of the graphene heating element 3 is usually very smooth, which makes it not easy to adsorb dust or other impurities; graphene has good chemical stability and is not easy to react with other substances under normal use conditions, so it is not easy to form compounds that are difficult to remove. Therefore, the graphene heating element 3 is more convenient to clean. Of course, a flowing water channel can also be opened at the bottom of the water tank body 1 so that the water can flow onto the graphene heating element 3, and the heat can directly act on the water without being blocked by the water tank body 1, so as to have a better heat transfer rate and higher energy utilization rate.

[0032] In some embodiments, a sunken platform is provided at the bottom of the water tank body 1. The lower part of the steam pipe 2 is inserted into the concave cavity of the sunken platform. The graphene heating element 3 is arranged below the sunken platform, which can further separate the water storage cavity 11 and the heating cavity 12 through the sunken platform, making the graphene heating element 3 farther away from the water storage cavity 11 and better restricting the heat transfer to the water storage cavity 11. Specifically, the concave cavity of the sunken platform matches the shape of the lower part of the steam pipe 2. The size of the graphene heating element 3 can be slightly larger than or equal to or slightly smaller than the lower surface of the sunken platform, and the optimal solution is that the size of the graphene heating element 3 is equal to the lower surface of the sunken platform. In one embodiment, the sunken platform can also be provided with a water flow channel so that water can flow onto the graphene heating element 3. Of course, the water can also be separated from the graphene heating element 3 through the bottom of the sunken platform. The sunken platform and the water tank body 1 are of an integral structure. Of course, it can also be connected to the water tank body 1 by welding or other connection methods.

[0033] In some embodiments, small water seepage holes or water seepage grooves can be provided at the bottom of the steam pipe 2 or the water tank body 1. Of course, it can also be a water seepage structure such as a water inlet gap.

[0034] In some embodiments, the main structure of the steam humidifier further includes an inner tank 4 that is open at the top and bottom, and the water tank body 1 passes through the inside of the inner tank 4. A gap 10 is provided between the inner wall of the inner tank 4 and the side wall of the water tank body 1, which can reduce the heat transfer through the gap 10.

[0035] Furthermore, the installation structure includes a heat insulation frame 5 connected to the lower part of the inner tank 4. A plurality of limiting blocks 6 are connected to the lower part of the heat insulation frame 5. An insertion groove 52 for inserting the graphene heating element 3 is formed between the plurality of limiting blocks 6 and the heat insulation frame 5. The heat insulation frame 5 and the heat insulation plate 8 reduce the heat transfer of the graphene heating element 3 to the outside, thereby reducing energy loss and preventing burns caused by touching. The inner tank 4 is connected to the heat insulation frame 5 by threaded fasteners or other connection methods. The heat insulation frame 5 is connected to the heat insulation plate 8 by threaded fasteners or other connection methods. The limiting blocks 6 are connected to the heat insulation frame 5 by threaded fasteners or other connection methods.

[0036] In some embodiments, a first sealing ring 71 is provided between the heat insulation frame 5 and the limiting block 6. This further reduces the heat dissipation and can also limit the penetration of external water onto the graphene heating element 3.

[0037] In some embodiments, a plurality of connecting feet 501 are circumferentially arranged on the heat insulation frame 5. The limiting block 6 is connected to the connecting feet 501 by threaded fasteners. A positioning groove 502 for inserting and positioning is further provided on the lower surface of the heat insulation frame 5 corresponding to the position of the limiting block 6. A plurality of supporting feet 503 are circumferentially arranged on the heat insulation frame 5. The heat insulation plate 8 is connected to the supporting feet 503 by threaded fasteners.

[0038] In some embodiments, the heat insulation frame 5 is provided with an insertion hole 51 into which the water tank body 1 can be inserted and abutted against the graphene heating element 3. The graphene heating element 3 abuts against the bottom of the water tank body 1 so as to better transfer heat energy to the heating cavity 12.

[0039] In some embodiments, a thermistor 20 and a thermostat 30 are further provided on the main body structure of the steam humidifier to assist in regulating the temperature of the graphene heating plate 3 on the circuit board.

[0040] In some embodiments, a limiting ring 53 is provided on the upper surface of the heat insulation frame 5. The lower part of the inner container 4 is sleeved outside the limiting ring 53. A second sealing ring 72 for sealing is provided between the limiting ring 53 and the inner wall of the inner container 4. The second sealing ring 72 further reduces heat dissipation and can also prevent external water from penetrating onto the graphene heating element 3. Among them, the limiting ring 53 and the heat insulation frame 5 are of an integral structure.

[0041] In some embodiments, a heat insulation layer 9 is further provided between the heat insulation plate 8 and the graphene heating element 3. The heat insulation layer 9 can be a heat insulation gap, or heat insulation cotton or other heat insulation fillers.

[0042] In some embodiments, the steam pipe 2 can be straight tubular, conical or trumpet-shaped, and of course, it can also be of other shapes.

[0043] Among them, when the steam pipe 2 is trumpet-shaped, the steam pipe 2 includes a straight pipe section 21 at the upper part and an arc-shaped cover section 22 communicated with the straight pipe section 21. A first heat insulation cavity 211 is provided in the pipe wall of the straight pipe section 21, and a second heat insulation cavity 221 is provided in the pipe wall of the arc-shaped cover section 22. The first heat insulation cavity 211 is communicated with the second heat insulation cavity 221. The first heat insulation cavity 211 and the second heat insulation cavity 221 form a heat insulation cavity, so as to reduce the heat transfer to the water in the water storage cavity 11, thereby reducing heat energy loss and improving energy utilization rate. The straight pipe section 21 and the arc-shaped cover section 22 are of an integral structure.

[0044] Furthermore, the second heat insulation cavity 221 gradually increases along the extending direction of the arc-shaped cover section 22 from top to bottom, that is, the closer to the graphene heating element 3, the larger the second heat insulation cavity 221. Generally speaking, the temperature closer to the heat source will be higher, and the larger second heat insulation cavity 221 can more effectively reduce the heat transfer from the steam conduit 2 to the water storage cavity 11, further improving the heat insulation effect and better reducing heat loss. The size of the graphene heating element 3 is less than or equal to the bottom size of the steam pipe 2.
