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 for reducing energy consumption. Background Art

[0002] With the increasing demand for environmental humidity control in industrial production and daily life, steam humidifiers are widely used because they can quickly and effectively increase air humidity. However, in existing steam humidifiers, there are problems such as high energy consumption and low humidification efficiency. Especially, there is a large amount of heat loss during the heating process, which not only increases the operating cost but also does not conform to the current development trend of energy conservation and emission reduction.

[0003] Currently, steam humidifiers on the market can be roughly divided into two categories: one is to directly heat the water mist in the air through electric heating elements, and the other is to use a steam pipeline to convert water into steam and then release it into the air. Although the latter improves the humidification efficiency to a certain extent, heat energy is easily transferred to the water tank through the steam pipeline, resulting in serious heat loss.

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

[0005] The utility model overcomes the deficiencies of the prior art and provides a main body structure of a steam humidifier that can reduce energy consumption.

[0006] The present utility model is achieved through the following technical solutions:

[0007] A main body structure of a steam humidifier for reducing energy consumption, including a water tank body. A steam pipeline is provided inside the water tank body. The steam pipeline 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 pipeline, and the heating cavity is arranged inside the steam pipeline. Water in the water storage cavity seeps into the heating cavity from between the bottom of the steam pipeline and the bottom of the water tank body. A heating device for heating the heating cavity to generate steam is provided below the water tank body at a position corresponding to the steam pipeline. A heat insulation cavity for heat insulation is provided on the pipe wall of the steam pipeline.

[0008] The main body structure of a steam humidifier for reducing energy consumption as described above, wherein the steam pipeline is in a straight tube shape, a conical shape or a trumpet shape.

[0009] The main body structure of a steam humidifier for reducing energy consumption as described above, when the steam pipeline is in an inverted trumpet shape, the steam pipeline includes a straight tube section at the upper part and an arc-shaped cover section communicated with the straight tube section. The heat insulation cavity includes a first heat insulation cavity arranged in the pipe wall of the straight tube section and a second heat insulation cavity arranged in the pipe wall of the arc-shaped cover section. The first heat insulation cavity is communicated with the second heat insulation cavity, and the second heat insulation cavity gradually increases from top to bottom along the extending direction of the arc-shaped cover section.

[0010] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein a bottom plate capable of separating a heating chamber from a heating device is provided at the bottom of the water tank body.

[0011] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein the size of the heating device is less than or equal to the bottom size of the steam pipe.

[0012] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein a sunken platform is provided at the bottom of the water tank body, the lower part of the steam pipe is inserted into the concave cavity of the sunken platform, and the heating device is arranged below the sunken platform.

[0013] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein the main body structure of the steam humidifier further includes an inner container that is open at both the top and the bottom, and the inner container is sleeved outside the water tank body.

[0014] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein a heat insulation plate for heat insulation is provided below the water tank body.

[0015] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein a heat insulation bracket for connecting the two is provided between the inner container and the heat insulation plate, and the heating device is connected to the heat insulation bracket.

[0016] A main body structure of a steam humidifier for reducing energy consumption as described above, wherein a heat insulation layer is provided between the heating device and the heat insulation plate.

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

[0018] 1. In this case, a heat insulation cavity for heat insulation is provided on the pipe wall of the steam pipe, so as to reduce the heat transfer to the water in the water storage cavity, thereby reducing the heat energy loss, improving the energy utilization rate, reducing the operation cost of the steam humidifier, and conforming to the current development trend of energy conservation and emission reduction.

[0019] 2. The steam pipe can be straight, conical or trumpet-shaped. When the steam pipe is trumpet-shaped, it includes a straight pipe section at the upper part and an arc-shaped cover section at the lower part. Water is heated in the arc-shaped cover section to form steam and water mist, and is discharged concentratedly through the straight pipe section, so that the steam and water mist have a faster flow rate, which helps to break the water droplets into smaller particles, thereby generating a finer water mist, and the water mist can spread into the air faster, which helps to increase the action range of the humidifier.

[0020] 3. The second heat insulation cavity gradually increases from top to bottom along the extending direction of the arc-shaped cover section, that is, the closer to the heating device, the larger the second heat insulation cavity. Generally speaking, the temperature is higher closer to the heating device. A larger second heat insulation cavity can more effectively reduce the heat transfer from the steam conduit to the water storage cavity, further improving the heat insulation effect and better reducing heat loss.

[0021] 4. The bottom of the water tank body is provided with a sunken platform. The lower part of the steam pipe is inserted into the concave cavity of the sunken platform. The heating device is arranged below the sunken platform, which can further separate the water storage cavity and the heating cavity through the sunken platform, making the heating device farther away from the water storage cavity and better restricting the heat transfer to the water storage cavity.

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

[0029] As Figures 1 to 5 shown, a main body structure of a steam humidifier for reducing energy consumption includes a water tank body 1. A steam pipe 2 is arranged 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 heating device 3 for heating the heating cavity 12 to generate steam is arranged below the water tank body 1 corresponding to the position of the steam pipe 2. The pipe wall of the steam pipe 2 is provided with a heat insulation cavity 21.

[0030] The pipe wall of the steam pipe 2 is provided with a heat insulation cavity 21 for heat insulation, so as to reduce the heat transfer to the water in the water storage cavity 12, thereby reducing heat energy loss, improving energy utilization efficiency, reducing the operating cost of the steam humidifier, and conforming to the current development trend of energy conservation and emission reduction.

[0031] In some embodiments, small water seepage holes or water seepage grooves may be provided at the bottom of the steam pipe 2 or the water tank body 1. Of course, it may also be a water seepage gap or other water seepage structures.

[0032] In some embodiments, the steam pipe 2 may be straight tubular, conical or trumpet-shaped. Of course, it may also be other shapes.

[0033] When the steam pipe 2 is in an inverted trumpet shape, the steam pipe 2 includes a straight pipe section 22 at the upper part and an arc-shaped cover section 23 communicated with the straight pipe section 22 to form an inverted funnel shape. Water is heated in the arc-shaped cover section 23 to form steam and water mist, and is centrally discharged through the straight pipe section 22, so that the steam and water mist have a faster flow rate, which helps to break the water droplets into smaller particles, thereby generating a more delicate water mist. The water mist can be diffused into the air faster, which helps to increase the action range of the humidifier. Among them, the straight pipe section 22 and the arc-shaped cover section 23 are integrally formed. The steam pipe 2 can be fixed in the water tank body 1 through a cover body or other structures.

[0034] Furthermore, the heat insulation cavity 21 includes a first heat insulation cavity 211 provided in the pipe wall of the straight pipe section 22 and a second heat insulation cavity 212 provided in the pipe wall of the arc-shaped cover section 23. The first heat insulation cavity 211 is communicated with the second heat insulation cavity 212. The second heat insulation cavity 212 gradually increases along the extending direction of the arc-shaped cover section 23 from top to bottom, that is, the closer to the heating device, the larger the second heat insulation cavity 212. Generally speaking, the temperature is higher closer to the heating device 3. The larger second heat insulation cavity 212 can more effectively reduce the heat transfer from the steam conduit 2 to the water storage cavity 11, can further improve the heat insulation effect, and better reduce the heat loss.

[0035] In some embodiments, the bottom of the water tank body 1 is provided with a bottom plate 14 that can separate the heating cavity 12 from the heating device 3. Of course, a water flow channel may also be provided on the bottom plate 14 so that water can flow to the heating device 3.

[0037] In some embodiments, a sunken platform 13 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 13. The heating device 3 is arranged below the sunken platform 13, which can further separate the water storage cavity 11 and the heating cavity 12 through the sunken platform 13, so that the heating device 3 is farther away from the water storage cavity 11, better restricting the heat transfer to the water storage cavity 11. Specifically, the concave cavity of the sunken platform 13 matches the shape of the lower part of the steam pipe 2. The size of the heating device 3 can be slightly larger than or equal to or slightly smaller than the lower surface of the sunken platform 13, and the optimal solution is that the size of the heating device 3 is equal to the lower surface of the sunken platform 13. In one embodiment, the sunken platform 13 can also be provided with a water flow channel to allow water to flow onto the heating device 3. Of course, the water can also be separated from the heating device 3 through the bottom of the sunken platform 13. The sunken platform 13 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.

[0038] In some embodiments, the heating device 3 can be a heating plate or a heating disc or a heating wire or a heating sheet. Of course, it can also be other heating structures. Specifically, it can be a PTC heating sheet or a graphene heating element.

[0039] In some embodiments, the main structure of the steam humidifier further includes an inner tank 4 that is open at both the top and bottom. The inner tank 4 is sleeved outside the water tank body 1. A heat insulation plate 5 for heat insulation is provided below the water tank body 1. A heat insulation frame 6 for connecting the two is provided between the inner tank 4 and the heat insulation plate 5. The heating device 3 can be connected to the heat insulation frame 6 through a threaded fastener or other connection structures, or the heating device 3 can also be clamped on the heat insulation frame 6. Among them, installation feet are provided on the outer side of the bottom of the inner tank 4, and installation holes are provided on the installation feet. The inner tank 4 is connected to the heat insulation frame 6 through a threaded fastener or other connection methods, and the heat insulation frame 6 is connected to the heat insulation plate 5 through a threaded fastener or other connection methods.
