Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an integrated plasma air disinfection and purification machine that adopts a multi-circulation method. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants, effectively improving air cleanliness. However, the most common air purifiers on the market currently draw in fresh outdoor air, process it through dust removal, dehumidification (or humidification), and cooling (or heating), and then deliver it indoors via a fan, replacing the existing indoor air. Fresh air systems can effectively improve indoor air quality, diluting indoor pollutants such as carbon dioxide, formaldehyde, and volatile organic compounds (VOCs), ensuring indoor air quality meets relevant standards.

[0003] However, existing air purifiers typically use simple ventilation methods when introducing fresh air, making little use of the heat from indoor and outdoor air, and the air source is relatively singular. Utility Model Content

[0004] Therefore, this utility model provides an integrated plasma air disinfection and purification machine that adopts a multi-circulation method to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-circulation plasma air disinfection and purification integrated machine includes a housing. Two air vents are provided at the bottom of one side wall of the housing: one is an outdoor fresh air vent and the other is an outdoor exhaust vent. Both the outdoor fresh air vent and the outdoor exhaust vent are connected to the inner sides of the housing and are connected to the outside. An air supply vent is provided at the top of the housing, and an indoor exhaust vent and an indoor return air vent are provided on one side wall of the housing.

[0007] The inner wall of the housing is provided with a partition, which divides the interior of the housing into upper and lower parts. A heat exchange module is provided on the lower side of the partition, and a filter module is provided on the upper side of the partition.

[0024] like Figures 1-3As shown, this utility model discloses a multi-cycle plasma air disinfection and purification integrated machine, including a housing 1. The housing 1 is characterized by having two air vents at the bottom of one side wall: an outdoor fresh air vent 2 and an outdoor exhaust vent 3. Both the outdoor fresh air vent 2 and the outdoor exhaust vent 3 are connected to the inner sides of the housing 1 and are connected to the outside. The housing 1 also has an air supply vent 4 at its top and an indoor exhaust vent 5 and an indoor return air vent 6 on one side wall.

[0025] The inner wall of the housing 1 is provided with a partition 7, which divides the interior of the housing 1 into upper and lower parts. A heat exchange module 8 is provided on the lower side of the partition 7, and a filter module 9 is provided on the upper side of the partition 7. The heat exchange module 8 divides the lower half of the housing 1 into four chambers, namely an air inlet chamber 10, an indoor exhaust chamber 11, an outdoor exhaust chamber 12, and an indoor fresh air chamber 13. The indoor exhaust chamber 11 and the outdoor exhaust chamber 12 are connected through the exhaust hole of the heat exchange module 8, and the outdoor exhaust chamber 12 is connected to the outdoor exhaust outlet 3, while the indoor exhaust chamber 11 is connected to the indoor exhaust outlet 5. The air inlet chamber 10 and the indoor fresh air chamber 13 are connected through the air inlet hole of the heat exchange module 8, and the air inlet chamber 10 is connected to the outdoor fresh air outlet 2 and the indoor return air outlet 6. The indoor fresh air chamber 13 is connected to the filter module 9 in the upper half of the housing 1 through the through hole on the partition 7.

[0026] The aforementioned housing 1 has three air ducts inside: a fresh air duct, an exhaust air duct, and an indoor recirculation air duct.

[0027] The fresh air duct includes an outdoor fresh air inlet 2, a fresh air filter, a fresh air fan 17, and an indoor air outlet 4. The outdoor fresh air inlet 2 is located on one side of the enclosure and is used to introduce fresh outdoor air. The fresh air filter is located behind the fresh air inlet and is used to filter dust, particulate matter, and other impurities from the outdoor air. The fresh air fan 17 is located behind the fresh air filter and is used to provide the power for the fresh air flow. The air outlet 4 is located on the other side of the enclosure and connects to the indoor environment, delivering filtered and disinfected fresh air into the room.

[0028] The exhaust duct includes an indoor exhaust vent 5, an exhaust filter, an exhaust fan 16, and an outdoor exhaust vent 3. The indoor exhaust vent 5 is located on one side of the enclosure and connects to the interior, used to exhaust stale indoor air. The exhaust filter is located behind the exhaust vent and is used to filter impurities in the exhaust air. The exhaust fan 16 is located behind the exhaust filter and provides the power for the exhaust airflow. The outdoor exhaust vent 3 is located on the other side of the enclosure and exhausts the filtered stale air outdoors.

[0029] The indoor recirculating air duct includes an indoor return air inlet 6, an indoor recirculating filter, an indoor recirculating fan, and an air supply outlet 4. The indoor return air inlet 6 is located on one side of the enclosure and connects to the interior, used to draw in indoor air. The indoor recirculating filter is located behind the indoor return air inlet 6 and is used to filter impurities from the indoor air. The indoor recirculating fan is located behind the indoor recirculating filter and provides the power for the indoor recirculating airflow. The air supply outlet 4 is located on the other side of the enclosure and connects to the interior, returning the filtered and disinfected indoor air to the room. It should be noted that the indoor return air inlet 6 and the outdoor fresh air inlet 2 share a filter and a fan, and are discharged into the room from the same air supply outlet 4. Their air sources are different; that is, the fresh air duct and the indoor recirculating air duct partially overlap.

[0030] The air passing through the fresh air duct and the indoor circulation duct is drawn to the filter module 9 by the fresh air fan 17, where it is purified and disinfected before being discharged into the room through the air outlet 4.

[0031] In a further embodiment, the heat exchange module 8 includes a heat exchange core, one channel of which connects the indoor exhaust cavity 11 and the outdoor exhaust cavity 12, and the other channel of which connects the air inlet cavity 10 and the indoor fresh air cavity 13. A primary filter 14 is provided at the air inlet of the heat exchange core located on one side of the indoor exhaust cavity 11.

[0032] The aforementioned heat exchange module 8 serves as a filtration device for the three air ducts, providing initial filtration of the air source. The heat exchange module 8 is a heat exchange core, which can utilize commercially available heat exchange core structures, which will not be elaborated upon here. It facilitates heat exchange between the exhaust duct and the fresh air duct / indoor circulation duct through channels in different directions, improving energy conversion efficiency. For the exhaust duct, to reduce pollutants discharged into the outdoor air, a primary filter 14 is installed at the exhaust duct outlet corresponding to the heat exchange core to filter dust and other pollutants from the air.

[0033] In a further embodiment, the filtration module 9 includes, from bottom to top, a particle module 91, a high-efficiency filter 92, and a plant antibacterial fragrance module 93. Fresh air enters the indoor fresh air chamber 13 through the heat exchange core from the air inlet chamber 10, and then enters the filtration module 9 from the indoor fresh air chamber 13. After being filtered by the particle module 91, the high-efficiency filter 92, and the plant antibacterial fragrance module 93 in sequence, the fresh air is discharged into the room through the fresh air outlet at the top of the housing 1.

[0034] By setting up a multi-stage filtration structure, the incoming air is disinfected and purified. The plasma disinfection and purification module includes a plasma generator and electrode plates. The plasma generator produces plasma, and the electrode plates accelerate the reaction between the plasma and pollutants such as bacteria, viruses, and harmful gases in the air, achieving the purpose of disinfection and purification. The plasma purification module causes some tiny particulate pollutants to agglomerate into larger particles, which are then easier to filter further by the subsequent high-efficiency filter 92.

[0035] In addition, the housing 1 has an opening on the side opposite to the fresh air valve and the exhaust air valve, and an inspection door 15 is provided at the opening. The inspection door 15 is detachably connected to the housing 1.

[0036] By setting a removable inspection door 15, the components inside the housing 1 can be inspected regularly, reducing the occurrence of malfunctions.

[0037] In some other embodiments, the filter module 9 may also include an ozone generator 18, which works in conjunction with the filter module 9 to perform ozone disinfection.

[0038] After the ozone disinfection function is turned on, the equipment enters the indoor circulation mode, the exhaust fan 16 is turned off, the outdoor fresh air inlet 2 is turned off, the indoor return air inlet 6 is turned on, and the fresh air fan 17 is turned on, so that the equipment can work in indoor circulation.

[0039] It should be noted that when the ozone function is activated, people and the machine cannot coexist; no one should be present on site. The default ozone activation time is 20 minutes, after which the ozone function will automatically turn off, the fresh air valve will open, the indoor air valve will close, and the fresh air fan and exhaust fan will run at high speed for 30 minutes to completely remove indoor ozone.

[0040] The beneficial effects of this utility model are as follows:

[0041] Multiple circulation modes: By setting up fresh air ducts, exhaust air ducts, and indoor recirculation air ducts, multiple air circulation modes are achieved. It can introduce fresh outdoor air, expel stale indoor air, and at the same time circulate and purify indoor air, effectively improving indoor air quality.

[0042] Highly efficient disinfection and purification: The plasma disinfection and purification module generates a large amount of plasma, which reacts chemically with pollutants in the air to quickly kill bacteria and viruses and decompose harmful gases, resulting in significant disinfection and purification effects.

[0043] Energy-saving design: Each air duct is set independently, and different circulation modes can be selected according to actual needs to avoid unnecessary energy consumption and achieve energy-saving operation.

[0044] Comprehensive filtration: Each air duct is equipped with a filtration device, which can effectively filter dust, particulate matter and other impurities in the air, further improving the air purification effect.

[0045] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0046] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0047] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
