Description

Technical Field

[0001] This invention relates to the field of control device technology, and more specifically to a heating energy-saving control device based on the Internet of Things and artificial intelligence. Background Technology

[0002] Based on the existing heating system, as people's living standards continue to improve, in the cold winter or on days when heating is needed, people are no longer limited to relying on their own heating to combat the harsh environment. They use heating devices to resist the cold winter, and in order to save energy, control devices are installed on the heating equipment, mainly to control the timely start-up and reduce unnecessary energy waste.

[0003] In summary, the inventors have found that existing heating energy-saving control devices mainly have the following defects: Based on the actual room temperature requirements, it takes a certain amount of time for the hot air output by the heating unit to reach the designated heating temperature. Because there are multiple air outlets on the air duct, the hot air discharged from the heating unit will gradually accumulate in the air duct, but it will be continuously discharged into the room from each air outlet. During this period, the temperature in the air duct will be higher in each section than the previous one, and the heat dissipation rate will be low. As a result, the temperature of the hot air discharged from each air outlet will be different, and sometimes it may even be higher than the designated heating temperature. Providing excessively hot air directly to the room is not good for human health and cannot provide a comfortable living environment for residents. Summary of the Invention

The heat-conducting seat is electrically connected to the control body and the motor, and the heat-conducting seat is installed on the inner wall of the air outlet duct.

[0010] As a further improvement of the present invention, the tube body is a rectangular hollow structure, and a heat-conducting seat is vertically fixed between it and the base plate. The tube body and the base plate are horizontally arranged on the inner wall of the control body, and the signal receiving board also contains a temperature sensor.

[0011] As a further improvement of the present invention, the assist body is also provided with guide members. There are two guide members, both of which are installed on the outside of the heat-conducting outer layer. The heat-conducting outer layer is sleeved on the outside of the column, and a telescopic rod is fixedly connected to the bottom of the heat-conducting outer layer. A bending plate is installed at the end of the telescopic rod.

[0012] As a further improvement of the present invention, a connecting rod is provided through the inside of the column, and is horizontally arranged inside the tube and rotates with the connecting rod, and the bending plate at the end of the telescopic rod is fitted with the inner wall of the tube.

[0013] As a further improvement of the present invention, the guide is further provided with a second mounting base, in which a curved plate and a filling soft plate are installed. The curved plate and the filling soft plate are two similar structures with upper and lower layers, and the cross-sections of the curved plate and the filling soft plate are both sharp-angled structures. Three embedding frames are provided at equal intervals at the edge of the filling soft plate, and an airbag is fixedly connected inside the embedding frame.

This hot air mixes with cold air within the air outlet, ensuring that the overall temperature of the mixed air within the air outlet reaches the designated heating temperature. The mixed air is then uniformly discharged to the air outlet using air pressure, ensuring that the air discharged from the air outlet is consistently at the designated heating temperature.

[0030] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: The present invention provides a heating energy-saving control device based on Internet of Things and artificial intelligence. Its structure includes: a solar panel 1, a cabinet door 2, a control body 3, a motor 4, and a heat conduction component 5. The solar panel 1 is installed on the top of the control body 3, and the heat conduction component 5 and the motor 4 are installed inside the control body 3. The cabinet door 2 is hinged to the surface of the control body 3.

[0031] The heat-conducting component 5 is provided with a heat-conducting seat 51, which is fixedly connected between the base plate 52 and the air outlet pipe 53. The outer side of the air outlet pipe 53 is provided with a first mounting seat 55, and the surface of the first mounting seat 55 is provided with two or more air outlets 54 at equal intervals, which can efficiently discharge the heating air that helps to discharge the air outlet pipe 53.

[0032] The air outlet duct 53 is also provided with a first fixing seat 531. The first fixing seat 531 is installed at the four corners of the inner wall of the duct body 533, and a signal receiving board 535 and a connecting rod 534 are provided between the first fixing seats 531. An auxiliary body 532 is horizontally installed in the middle of the two connecting rods 534. The auxiliary body 532 can evenly mix the hot and cold air inside the duct body 533.

[0033] Among them, the heat conduction seat 51 is horizontally fixed inside one side of the tube body 533, and the length of the heat conduction seat 51 is only slightly smaller than the length of the tube body 533, which can maximize and evenly dissipate heat within the cuboid structure of the tube body 533. Multiple heat conduction seats 51 are horizontally placed inside the control body 3 through the base plate 52, and the arrangement of multiple heat conduction seats 51 can better achieve the function of heating and energy saving.

[0034] The solar panel 1 is electrically connected to the motor 4 inside the control body 3, and the heat conduction component 5 and the solar panel 1 cooperate with each other through various components and sensors contained in the control body 3 by means of signal transmission, further promoting the development of the next process and achieving the effect of energy-saving control for indoor heating.

[0035] The base plate 52 is fixedly connected to the inner wall surface of the control body 3, and a heat-conducting seat 51 is installed inside the base plate 52. The heat-conducting seat 51 is electrically connected to the control body 3 and the motor 4. The heat-conducting seat 51 is installed on the inner wall of the air outlet duct 53, which is conducive to horizontal heating in the air outlet duct 53, so that the air outlet duct 53 is warmed at a uniform temperature from beginning to end.

[0036] The tube body 533 is a rectangular hollow structure, and a heat-conducting seat 51 is vertically fixed between it and the base plate 52. The tube body 533 and the base plate 52 are horizontally arranged on the inner wall of the control body 3. The signal receiving board 535 also contains a temperature sensor, which can sense the temperature of the heating air in real time at both ends of the tube body 533.

[0037] The assisting body 532 is also provided with guide members 5321. There are two guide members 5321, both of which are installed on the outside of the heat-conducting outer layer 5322. The heat-conducting outer layer 5322 is sleeved on the outside of the column 5323. The bottom of the heat-conducting outer layer 5322 is fixedly connected to a telescopic rod 5325. A bending plate 5324 is installed at the end of the telescopic rod 5325. The cross-section of the bending plate 5324 is a bendable structure, which allows the bending plate 5324 to open and close synchronously with the up and down movement of the telescopic rod 5325 inside the tube 533.

[0038] The column 5323 is internally connected to a connecting rod 534, which can evenly distribute the hot and cold air inside the tube 533. The connecting rod 534 is horizontally positioned inside the tube 533 and can rotate. The bending plate 5324 at the end of the telescopic rod 5325 is fitted with the inner wall of the tube 533, allowing the bending plate 5324 to extend inside the tube 533 by changing its bending degree, further mixing the heating air, so that it can be efficiently guided from the tube 533 to the air outlet 54.

[0039] The guide 5321 is further provided with a second mounting base 3211. The second mounting base 3211 is equipped with a curved plate 3212 and a filling soft plate 3213. The curved plate 3212 and the filling soft plate 3213 are similar structures with upper and lower layers. The cross-sections of the curved plate 3212 and the filling soft plate 3213 are both sharp-angled structures. Three embedding frames 3215 are equidistantly provided at the edge of the filling soft plate 3213. The airbag 3214 is a rugby ball structure with both ends fixed inside the embedding frames 3215. When the filling soft plate 3213 deforms, it will be squeezed and deformed one after another from the outside to the inside. This can provide the two filling soft plates 3213 with deformation space around the outside of the column 5323 and can also promote the reciprocating rotation of the column 5323 inside the tube 533.

[0040] The second mounting base 3211 is fixedly installed on the outside of the heat-conducting outer layer 5322, while the bent plate 3212 and the filling soft plate 3213 are deformable and will fit with the inner wall of the tube body 533 with a gap. The two oppositely arranged filling soft plates 3213 can deform around the outside of the column body 5323, so that the column body 5323 can rotate back and forth inside the tube body 533.

[0041] The specific functions and operation procedures of this embodiment are as follows: In this invention, the solar panel 1 converts absorbed solar energy into electricity to provide power support for the control unit 3 and the motor 4. After the specified heating temperature is input on the control panel of the control unit 3, the internal heat-conducting component 5 will be activated simultaneously, causing the heat-conducting seat 51 on the bottom plate 52 of the heat-conducting component 5 to heat up, heating the air in the pipe body 533 of the air outlet duct 53. During this process, the hot air in the pipe body 533 merges with the cold air in the pipe body 533 from top to bottom, and will come into contact with the horizontally arranged column 5323 and the heat-conducting outer layer 532 inside the pipe body 533. 2. Externally, this causes the heat-conducting outer layer 5322 to heat up simultaneously, and also causes the bent plate 3212 and the filling soft plate 3213 on the second mounting base 3211 outside the heat-conducting outer layer 5322 to bend in the same direction. The filling soft plate 3213 then presses the embedded frame 3215 one by one from the outside to the inside, causing the embedded frame 3215 to clamp and compress the airbags 3214 on its inner wall, further deforming them. This causes the airbags 3214 to expand and contract within the embedded frame 3215 as the filling soft plate 3213 deforms, thus providing a buffer for the deformation of the filling soft plate 3213. The reset provides elastic power, and the stored force supports the reset of the bending plate 3212 and the filling soft plate 3213. This causes the bending plate 3212 and the filling soft plate 3213 to drive the heat-conducting outer layer 5322 and the column 5323 to rotate back and forth inside the tube body 533, with the connecting rod 534 as the fulcrum. This causes the telescopic rod 5325 at the bottom of the heat-conducting outer layer 5322 to be thrown outward by centrifugal force, which can drive the bending plate 5324 to move back and forth in the same direction. In conjunction with the back and forth swaying of the heat-conducting outer layer 5322 and the column 5323 inside the tube body 533, the tube body 533 is driven with high quality. The mixing of hot and cold air inside the duct 53 helps to ensure that the air in each section of the duct 53 is mixed to a uniform temperature. In conjunction with the temperature sensor of the signal receiving board 535, the temperature data of the mixed gas inside the duct 533 is monitored for heating, and the temperature is detected in real time to see if the specified temperature is reached. When the specified heating temperature is reached inside the duct 533, the telescopic rod 5325 shakes the support bending plate 5324 to drive the heated air to the air outlet 54 outside the first mounting base 55, and the air pressure is used to input the mixed heated air into each air outlet 54.

[0042] Example 2: Figures 6 to 7 As shown: This invention provides a heating energy-saving control device based on the Internet of Things and artificial intelligence. Its structure includes an inclined plate 541 at the air outlet 54. The inclined plate 541 is inclined and equidistantly arranged inside the connecting pipe 542 to receive the heating air in a concentrated manner. An opening is opened at the bottom of the connecting pipe 542. An accelerator 543 and an outer pipe 544 are vertically fitted inside the opening. An auxiliary ball 545 is installed at the end of the outer pipe 544 through a second fixing seat 546. The accelerator 543 and the auxiliary ball 545 are vertically arranged inside the connecting pipe 542 and the outer pipe 544 and act on the same vertical line, so that the heating air driven by the accelerator 543 can be transferred in a straight line to the outer pipe 544 and discharged in equal amount by the plate-like structure of the auxiliary ball 545.

[0043] The connecting pipe 542 and the outer pipe 544 are vertically installed on the outside of the pipe body 533 through the first mounting base 55, and the connecting pipe 542 and the outer pipe 544 are interconnected with the pipe body 533. The surface of the auxiliary ball 545 at the end of the outer pipe 544 is a sheet-like structure, and the auxiliary ball 545 is rotatably fitted between the second fixed base 546, so that it can receive an equal amount of heating air and discharge it to the outside while rotating.

[0044] The accelerator 543 is further provided with striped plates 5431, which are installed between the slider 5432 and the rotating rod 5433. There are four striped plates 5431 and rotating rods 5433, and their ends are all fixedly connected to the disc 5434. The disc 5434 is fitted with a rotating shaft 5435 in the middle, so that the striped plates 5431 and rotating rods 5433 on the outside of the rotating shaft 5435 cooperate with each other to rotate like a fan, directionally carrying the heating air.

[0045] The striped plate 5431 and the slider 5432 are slidably fitted inside the connecting pipe 542, while the rotating shaft 5435 is centrally and vertically installed in the middle of the disc 5434 and suspended at the opening of the connecting pipe 542 and the outer pipe 544, providing a fulcrum for the rotation of the striped plate 5431 and the rotating rod 5433. The stripes on the surface of the striped plate 5431 can better wind and heat the air.

[0046] The specific functions and operation procedures of this embodiment are as follows: In this invention, when the connecting pipe 542 at the air outlet 54 receives heated air, it first uses the inclined plates 541 inside the connecting pipe 542 to gather at the bottom opening of the connecting pipe 542. This blows the outer edges of the striped plates 5431 and sliders 5432 outside the rotating shaft 5435. Supported by the rotating rod 5433, they slide on the inner wall of the bottom opening of the connecting pipe 542, causing each striped plate 5431 and slider 5432 to rotate like a fan outside the disc 5434. This circulates and guides the heated air, allowing it to continue penetrating the air. The air flowing inside the external pipe 544 blows the auxiliary ball 545 between the second fixed seats 546 to slowly roll, causing the sheet-like structure on its surface to carry the heating air outwards. This ensures that each external pipe 544 discharges heating air at the specified heating temperature, allowing the heating air to be directionally transferred from the air outlet 54 to the external pipe 544 at a uniform temperature. From there, the heating air evenly heats the room, maintaining human comfort and providing a better living environment for residents. This also ensures the heating energy-saving control effect of the device based on Internet of Things and artificial intelligence.

[0047] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
