Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to an energy-saving fresh air system. Background Art

[0002] The fresh air system is a mechanical ventilation device that can continuously bring in fresh air from the outside and expel dirty air from the room without opening windows, so that the indoor air can be constantly renewed and the indoor environment can be improved. At the same time, the filter of the fresh air system can also filter out various pollutants contained in the outside air, such as haze, dust, allergens, car exhaust, etc.

[0003] Some people think that fresh air system can cool down the room, because it has heat exchange function, which can cool down the hot air outside before sending it into the room. Putting aside the issue of heat exchange efficiency, the function of the heat exchange core is not to cool down the hot air outside, but to recover some of the energy in the cold air discharged from the air-conditioned room, so that the incoming air becomes less hot. Conceptually speaking, fresh air system cannot cool down the room, and similarly, fresh air system cannot heat the room either.

[0004] The existing fresh air system sucks in the outside air and then sends the fresh air to each room through the air distribution box. However, when used in winter, although the existing fresh air system partially contains a heat exchange system, it cannot replace the air conditioner to achieve heating. The fresh air sucked in from the outside is still cold air, which will greatly reduce the indoor temperature when used and make the air conditioner bear a greater heating burden. Similarly, when used in summer, because it cannot be cooled, the cold air in the house is discharged to the outside during use, and the hot air outside is sucked into the house, resulting in excessive waste of resources.

[0005] For this reason, an energy-saving fresh air system is proposed. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0043] The embodiment of the present invention provides an energy-saving fresh air system, which solves the problem that the existing fresh air system sucks in the outside air and then sends the fresh air into each room through the air distribution box. However, when used in winter, although the existing fresh air system partially contains a heat exchange system, it cannot replace the air conditioner to achieve heating. The fresh air sucked in from the outside is still cold air, which will greatly reduce the indoor temperature when used and make the air conditioner bear a greater heating burden; similarly, when used in summer, because it cannot be cooled, the cold air in the room is discharged to the outside during use, and the hot air outside is sucked into the room, resulting in excessive waste of resources; and the technical problem that condensed water mixed with dust and impurities adheres to the inner wall of the heating box and cannot be removed during the operation of the machine;

[0044] The technical solution in the embodiment of the present invention is to solve the above technical problems, and the overall idea is as follows: the existing fresh air system inhales the outside air and then sends the fresh air into each room through the air distribution box. However, when used in winter, although the existing fresh air system partially contains a heat exchange system, it cannot replace the air conditioner to achieve heating. The fresh air inhaled from the outside is still cold air, which will greatly reduce the indoor temperature when used and make the air conditioner bear a greater heating burden; similarly, when used in summer, because it cannot be cooled, the cold air in the house is discharged to the outside during use, and the hot air outside is inhaled into the house, resulting in excessive waste of resources. Therefore, the present invention sets a heat changing mechanism at the air inlet, performs temperature change treatment on the inhaled fresh air in different working modes according to cold or hot weather, and then stores the treated gas in the air storage box, so that the air entering the room is fresh air of suitable temperature.

[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] See also Figures 1 to 5 , the present invention provides a technical solution:

[0047] An energy-saving fresh air system, such as Figure 1 As shown, including:

[0048] An air inlet 1, the air inlet 1 is used to inhale fresh air from the outside;

[0049] An exhaust pipe 2, wherein the exhaust pipe 2 is fixedly installed inside the air inlet 1;

[0050] A heat changing mechanism 3, the heat changing mechanism 3 is fixedly mounted on the upper end of the outer side of the air inlet 1; the heat changing mechanism 3 can perform temperature changing treatment on the air entering from the air inlet 1 in hot weather or cold weather;

[0051] During operation, the air inlet 1 draws in fresh air from the outside, and the exhaust duct 2 discharges the dirty air in the room. The exhaust duct 2 is installed inside the air inlet 1. Since the gas in the exhaust duct 2 is the air in the house, the fresh air exchanges heat with the dirty air in the house, so that the temperature of the inhaled fresh air is as close to the indoor temperature as possible, reducing the overall load of the device. The inhaled fresh air enters the heat changing mechanism 3 through the air inlet 1, and the heat changing mechanism 3 performs heating or cooling processing on the fresh air.

[0052] As an embodiment of the present invention, Figure 2 , Figure 3 and Figure 5 As shown, the heat changing mechanism 3 includes:

[0053] A heating box 31, the heating box 31 is fixedly mounted on the upper end of the air inlet 1, and a water outlet 32 ​​is provided on the upper side of the rear end of the heating box 31; a first through hole 311 is provided at the lower end of the heating box 31, and a second through hole 312 is provided at the upper end of the heating box 31;

[0054] A water storage tank 34, the water storage tank 34 is fixedly installed at the lower end of the heating box 31, a water inlet 341 is opened at the lower side of the front end of the water storage tank 34, and a drain outlet 342 is opened at the lower side of the rear end of the water storage tank 34;

[0055] The movable tube 35 is movably mounted inside the heating box 31; the air inlet 1 is fixedly mounted inside the first through hole 311, and a rubber pad 7 is fixedly mounted inside the second through hole 312; the outer side of the movable tube 35 coincides with the upper opening of the heating box 31, and a baffle 351 is fixedly mounted on the lower end of the movable tube 35, the outer side of the baffle 351 is lower than the inner side, and the distance between the outer side of the baffle 351 and the inner wall of the heating box 31 is smaller than the distance between the inner side of the scraper 42 and the inner wall of the heating box 31; the gas storage mechanism 5 is fixedly mounted on the upper end of the heating box 31, and the gas storage mechanism 5 includes:

[0056] An air storage box 51, the air storage box 51 is fixedly mounted on the upper end of the heating box body 31, a third through hole 52 is opened at the lower end of the air storage box 51, and a fourth through hole 53 is opened at the upper end of the air storage box 51;

[0057] An air intake pipe 54 is fixedly installed on the upper end of the fourth through hole 53; the second through hole 312 has the same diameter as the third through hole 52, and a heat preservation sleeve 33 is fixedly installed on the outer side of the air storage box 51 and the heating box body 31;

[0058] When the outside temperature is too high, the heating box 31 does not work and is only used as a container. The movable pipe 35 is located at the bottom at this time. The movable pipe 35 and the heating box 31 form a container. The condensate in the condensing device enters from the water inlet 341, fills the container, and is then discharged from the water outlet 32 ​​at the upper end.

[0059] When the outside temperature is too low, the heating box 31 is powered on for heating, and the movable pipe 35 is at the uppermost end. Fresh air from the outside enters the heating box 31, is heated by the heating box 31, and is then discharged through the movable pipe 35. When the device stops working, the heating box 31 cools down quickly, so the air forms condensed water on the inner wall, and the generated condensed water is finally collected in the water storage tank 34.

[0060] In this embodiment, the height of the outer side of the baffle 351 is lower than that of the inner side, so that when the movable tube 35 moves, it contacts the second through hole 312 and the condensed water on the outer wall of the movable tube 35 is scraped off and falls into the water collection tank 34 after passing through the baffle 351. The distance between the outer side of the baffle 351 and the inner wall of the heating box body 31 is smaller than the distance between the inner side of the scraper 42 and the inner wall of the heating box body 31, so that when the movable tube 35 moves, the baffle 351 will not contact the scraper 42 and affect the movement. The rubber pad 7 is installed in each through hole to improve the sealing performance. At the same time, due to the friction between the movable tube 35 and the through hole, the existence of the rubber pad 7 greatly reduces the wear.

[0061] As an embodiment of the present invention, Figure 5 As shown, the cleaning mechanism 4 is movably installed inside the heating box 31, and the cleaning mechanism 4 includes:

[0062] The electromagnet 41 is fixedly mounted on the upper end of the heating box 31;

[0063] The scraper 42 is movably installed inside the heating box 31; the scraper 42 is a permanent magnet, the cross section of the scraper 42 is an oblique line, and the side close to the center is lower than the side away from the center, and the side of the scraper 42 close to the heating box 31 is made of rubber;

[0064] During operation, the heat-changing mechanism 3 will generate condensed water on the inner wall, and impurities such as dust will be suspended in the air. After the condensed water adheres to the inner wall and dries, impurities such as dust will adhere to the inner wall over time, which will produce bacterial odor and greatly reduce the air quality. The scraper 42 is a permanent magnet. The direction of the current is changed by an external power supply, so that the magnetic pole of the electromagnet 41 changes, and finally the scraper 42 is driven to move up and down. The side close to the heating box 31 is chlorosulfonated polyethylene rubber, which reduces wear and greatly improves the water and impurity removal capabilities.

[0065] As an embodiment of the present invention, Figures 1 to 3 As shown, the control mechanism 6 is movably installed inside the heat changing mechanism 3, and the control mechanism 6 includes:

[0066] A control terminal, wherein the control terminal is integrated into a remote controller;

[0067] A first valve 61, which is movably embedded in the drain port 342;

[0068] A first solenoid valve 62, which is movably embedded in the water inlet 341;

[0069] A second solenoid valve 63, which is movably embedded in the water outlet 32;

[0070] A third solenoid valve 64, wherein the third solenoid valve 64 is movably embedded in the upper end of the movable tube 35;

[0071] A fourth solenoid valve 65, wherein the fourth solenoid valve 65 is movably embedded in the fourth through hole 53;

[0072] Rotating rollers 66, rotating rollers 66 are movably mounted on both sides of the movable tube 35, and a micro motor 67 is fixedly mounted on the rear end of the rotating rollers 66;

[0073] In this embodiment, the first valve 61 is a manual valve, which is opened manually when needed to discharge the internal condensed water for secondary use, which is more environmentally friendly; it should be noted that the condensed water is condensed water generated by air condensation;

[0074] In this embodiment, a driving gear 71 is fixedly installed at the front end of the micro motor 67, a first bearing seat 72 is fixedly installed on the left side of the driving gear 71, a driven gear 73 is movably installed on the upper end of the first bearing seat 72, the two gears are of the same size, a pinion is fixedly installed at the rear end of the two rotating rollers 66, a second bearing seat 74 is fixedly installed on the upper end of the electromagnet 41, the rotating roller 66 is movably installed on the second bearing seat 74, the left pinion 75 is meshed with the driven gear 73, and the right pinion 76 is meshed with the driving gear 71. When working, the micro motor 67 drives the driving gear 71 to rotate, the driving gear 71 drives the driven gear 73 and the right pinion 76 to rotate, and the driven gear 73 drives the left pinion 75 to rotate, so that the rotation directions of the left and right pinions are opposite, and the second bearing seat 74 provides pressure to the rotating roller 66 so that the rotating roller 66 can drive the movable tube 35 to move.

[0075] When the outside temperature is too high: at this time, the first solenoid valve 62 and the second solenoid valve 63 are opened, and the micro motor 67 drives the rotating roller 66 to move, so that the movable pipe 35 moves to the lowest position. At this time, the air inlet 1 sucks in the outside air. Since the movable pipe 35 is at the lowest position, the fresh air does not enter the heating box 31, but directly passes through the movable pipe 35. The first solenoid valve 62 and the second solenoid valve 63 are opened and connected to the condensing device. The movable pipe 35 and the heating box 31 are directly filled with condensate to cool the air inside the movable pipe 35. At the same time, since the exhaust pipe 2 is installed inside the air inlet 1, the gas in the exhaust pipe 2 is the gas in the house that has been cooled by air conditioning and other equipment. The gas in the exhaust pipe 2 exchanges heat with the gas in the movable pipe 35 through the exhaust pipe 2, and further cools the gas in the movable pipe 35. After the gas reaches the preset temperature, the third solenoid valve 64 is opened to discharge the gas into the gas storage box 51 for storage. When needed, the fourth solenoid valve 65 is opened to transport the gas in the gas storage box 51 to the house.

[0076] When the outside temperature is too low: at this time, the first solenoid valve 62 and the second solenoid valve 63 are closed, and the micro motor 67 drives the rotating roller 66 to move, so that the movable tube 35 moves to the highest position. At this time, the outside air is sucked in through the air inlet 1 and enters the interior of the heating box 31. The heating box 31 is powered on and heated, and then the fresh air inside is heated. After the gas reaches the preset temperature, the third solenoid valve 64 is opened to discharge the gas into the gas storage box 51 for storage. When needed, the fourth solenoid valve 65 is opened to transport the gas in the gas storage box 51 to the house.

[0077] How it works:

[0078] When the outside temperature is too high: at this time, the first solenoid valve 62 and the second solenoid valve 63 are opened, and the micro motor 67 drives the rotating roller 66 to move, so that the movable pipe 35 moves to the lowest position. At this time, the air inlet 1 sucks in the outside air. Since the movable pipe 35 is at the lowest position, the fresh air does not enter the heating box 31, but directly passes through the movable pipe 35. The first solenoid valve 62 and the second solenoid valve 63 are opened and connected to the condensing device. The movable pipe 35 and the heating box 31 are directly filled with condensate to cool the air inside the movable pipe 35. At the same time, since the exhaust pipe 2 is installed inside the air inlet 1, the gas in the exhaust pipe 2 is the gas in the house that has been cooled by air conditioning and other equipment. The gas in the exhaust pipe 2 is further cooled by heat exchange with the gas in the movable pipe 35 through the exhaust pipe 2. After the gas reaches the preset temperature, the third solenoid valve 64 is opened to discharge the gas into the gas storage box 51 for storage. When necessary, the fourth solenoid valve 65 is opened to transport the gas in the gas storage box 51 to the house. It should be noted that when the outside temperature is too high, the heating box 31 does not heat and is only used as a container. The movable pipe 35 is located at the bottom at this time. A container is formed between the movable pipe 35 and the heating box 31. The condensate in the condensing device enters from the water inlet 341, fills the container and is then discharged from the water outlet 32 ​​at the upper end.

[0079] When the outside temperature is too low: at this time, the first solenoid valve 62 and the second solenoid valve 63 are closed, and the micro motor 67 drives the rotating roller 66 to move, so that the movable tube 35 moves to the highest position. At this time, the outside air is sucked in through the air inlet 1 and enters the interior of the heating box 31. The heating box 31 is powered on for heating and then heats the fresh air inside. After the gas reaches the preset temperature, the third solenoid valve 64 is opened to discharge the gas into the gas storage box 51 for storage. When necessary, the fourth solenoid valve 65 is opened to transport the gas in the gas storage box 51 to the house; when the outside temperature is too low, the heating box 31 is powered on for heating, and the movable tube 35 is at the uppermost end at this time. The fresh air from the outside enters the heating box 31, is heated by the heating box 31, and then is discharged through the movable tube 35. When the device stops working, the heating box 31 cools down quickly, so the air will form condensed water on the inner wall, and the generated condensed water will finally be collected in the water storage tank 34;

[0080] During operation, the heat-changing mechanism 3 will generate condensed water on the inner wall, and impurities such as dust will be suspended in the air. After the condensed water adheres to the inner wall and dries, impurities such as dust will adhere to the inner wall over time, which will produce bacterial odor and greatly reduce the air quality. The scraper 42 is a permanent magnet. The direction of the current is changed by an external power supply, so that the magnetic pole of the electromagnet 41 changes, and finally the scraper 42 moves up and down. The side close to the heating box 31 is chlorosulfonated polyethylene rubber, which reduces wear and greatly improves the water and impurity removal capabilities.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
