Description

Technical Field

[0001] The utility model belongs to the technical field of heating and ventilation equipment, and particularly relates to a heating and ventilation device for indoor buildings. Background Technique

[0002] With the continuous improvement of people's living standards, the requirements for the indoor environment of buildings are also getting higher and higher. In cold seasons, the indoor heating system can provide a comfortable temperature; while a good ventilation system can ensure the freshness of indoor air and create a healthy and comfortable living and working environment for people. Traditional indoor heating devices for buildings mainly use equipment such as boilers and radiators. The water is heated by burning fuel or electricity, and then the hot water is transported to the radiator through pipes. The radiator dissipates heat into the indoor air through convection and radiation, thereby increasing the indoor temperature. However, this traditional heating device has some problems, such as high energy consumption, low thermal efficiency, uneven temperature distribution, etc.

[0003] Patent No. CN212962043U proposes a heating and ventilation device in a heating building, including a wall and an air inlet pipe. The air inlet pipe is installed on the outer wall of the upper right side of the wall. A dust-proof cover is sleeved on the outer circumference of the right end of the air inlet pipe. When ventilating, the heating pipe can heat the air in the air inlet pipe, and then blow the heated air to the connecting pipe and the ventilation pipe, and finally enter the house through the ventilation holes. When the air enters from the air inlet pipe, most of the dust is blocked by the dust-proof net, and then the honeycomb activated carbon adsorbs the tiny particles in the air, and finally the air is filtered again by the filter cotton to ensure that the air has no impurities and peculiar smell. At the same time, the suction motor sucks the air in the house out of the house to ensure the smooth flow of air. In this way, it can effectively realize air circulation and effectively filter the outside air, effectively improving the indoor air quality and ensuring fresh and clean air indoors.

[0028] Such as Figure 3 、 Figure 4 and Figure 5As shown, there is a heating component 2. The heating component 2 includes a positioning groove 201, a pipe body 202, a preheating groove 203, a heater 204, a first heat conducting plate 205, a second heat conducting plate 206, and a third heat conducting plate 207.

[0031] The ceramic heating tube 209 is electrically connected to the heater 204. The ceramic heating tube 209 is a hollow positive temperature coefficient thermistor ceramic pipe, and a plurality of intake holes are opened on the surface of the pipe.

[0032] It should be further explained that when it is necessary to heat the outside air, the heater 204 is started to heat the ceramic heating tube 209. At this time, the heat generated by the ceramic heating tube 209 is conducted to the first heat conducting plate 205, the second heat conducting plate 206, and the third heat conducting plate 207 through the preheating groove 203. Then, the blower 4 is started to draw the outside air into the inside of the pipe body 202.

A small servo motor 305 is fixedly installed on one side of the positioning block 304. The output end of the small servo motor 305 is fixedly installed with a turntable 307. The turntable 307 is movably installed on one side of the conductive plate 306. A suction cup 308 is fixedly installed at the bottom of the turntable 307. A conductive contact 309 is fixedly installed on one side of the suction cup 308. The conductive contact 309 is movably connected to one side of the conductive plate 306.

[0034] The dust removal component 3 further includes a first suction pipe 310, a rotating ring 311, a hollow ring 312, a second suction pipe 313 and a vacuum pump 314. The first suction pipe 310 is fixedly installed on one side of the suction cup 308. A rotating ring 311 is fixedly installed on one side of the first suction pipe 310. The rotating ring 311 is movably installed inside the hollow ring 312. One side of the hollow ring 312 is communicated with a second suction pipe 313. One side of the second suction pipe 313 is communicated with a vacuum pump 314. The vacuum pump 314 is fixedly installed on one side of the second outer shell 303.

[0035] The dust-proof net 301 is made of an aluminum plate with a thickness of 1 cm, and a number of air intake holes are arranged on the surface of the aluminum plate. The electrostatic generator 302 is internally provided with a friction track and a micro servo motor, and static electricity is generated by the friction between the friction track and the dust-proof net 301. The conductive contact 309 is composed of a contact plate made of copper and an arc-shaped guide plate, wherein the contact plate is in contact with the dust-proof net 301, and the arc-shaped guide plate is in contact with the conductive plate 306.

[0036] It should be noted that when it is necessary to clean the dust on the surface of the dust-proof net 301, the small servo motor 305 is started to drive the turntable 307 to rotate. Then the vacuum pump 314 is started to pump vacuum. The dust on the surface of the dust-proof net 301 is sucked by the negative pressure generated at the connection between the suction cup 308 and the dust-proof net 301. At the same time, when the suction cup 308 is about to move to the uncleaned area, the conductive contact 309 will guide the static electricity near the dust-proof net 301 to the conductive plate 306 for release, which is convenient for dust cleaning.

[0037] The working principle of the above embodiment is as follows: First, start the heater 204 to heat the ceramic heating tube 209. At this time, the heat generated by the ceramic heating tube 209 is conducted to the first heat conduction plate 205, the second heat conduction plate 206, and the third heat conduction plate 207 through the preheating tank 203. Then, start the fan 4 to draw the outside air into the interior of the pipe body 202. In this process, after the outside air is preheated through the narrow pipe formed by the first heat conduction plate 205, the second heat conduction plate 206, and the third heat conduction plate 207, it is filtered through the dust-proof net 301, and finally, after being heated by the ceramic heating tube 209, warm air is formed, and the heating efficiency is high.

[0038] Next, start the small servo motor 305 to drive the turntable 307 to rotate. Then, start the vacuum pump 314 to pump out the air. Use the negative pressure generated at the connection between the suction cup 308 and the dust-proof net 301 to suck the dust on the surface of the dust-proof net 301. At the same time, when the suction cup 308 is about to move to the un-cleaned area, the conductive contact 309 will guide the static electricity near the dust-proof net 301 to the conductive plate 306 for release, which is convenient for dust cleaning.

[0039] Finally, the operator connects a hose to the vacuum pump 314 to guide the extracted dust to be centrally collected into the container, completing the cleaning of the dust.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
