DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-Figure 3 As shown, this embodiment discloses a pollutant separation type kitchen and bathroom air conditioner return air structure, including a housing 1;

[0028] The shell 1 has an exhaust chamber 2, an indoor return air chamber 3 and an indoor supply air chamber 4;

[0029] The exhaust cavity 2 is provided with an outdoor exhaust port 21 connected to the outdoor environment, and an exhaust fan 5 is provided in the exhaust cavity 2;

[0030] The indoor air supply cavity 4 is provided with an indoor air supply port 41 connected to the indoor environment, and a supply fan 6 is provided in the indoor air supply cavity;

[0031] The indoor return air chamber 3 is provided with an indoor return air outlet 31 connected to the indoor environment. A filter screen 7 is provided between the indoor return air chamber 3 and the indoor supply air chamber 4. The indoor return air chamber 3 is connected to the indoor supply air chamber 4 through the filter screen 7. The indoor return air chamber 3 is also connected to the exhaust chamber 2.

[0032] When the above structure is in use, the indoor return air flows into the indoor return air chamber 3 through the indoor return air port 31. Due to the wind resistance generated by the filtering of the filter 7, the large molecular particle pollutants with larger mass in the air flow are relatively difficult to pass through the filter 7, but will be sucked into the exhaust chamber 2 by the exhaust fan 5 with smoother ventilation and greater suction force and discharged through the outdoor exhaust port 21, while the clean air molecules with relatively smaller mass in the air flow will pass through the filter 7 and be sucked into the indoor air supply chamber 4 by the supply fan 6 on the other side, and delivered to the indoor environment through the indoor air supply port 41, thereby realizing the air supply function of cold air or warm air.

[0033] The above structure can filter out large molecular particle pollutants by adding an indoor return air chamber 3 and setting a filter 7 between the indoor return air chamber 3 and the indoor supply air chamber 4, so that the large molecular particle pollutants are sucked into the exhaust chamber 2 and finally discharged into the building flue or exhaust gas exhaust channel through the external exhaust pipe 25, so that only relatively clean air can enter the indoor supply air chamber 4, thereby ensuring the cleanliness of the indoor supply air; the above structure can separate the exhaust smoke and water vapor to the maximum extent and discharge them outdoors, optimize and reduce the filtering load of the indoor supply air filter 7, and alleviate the cleaning frequency of the kitchen and bathroom space filter 7 to the greatest extent, thereby effectively reducing the cleaning difficulty.

[0034] It should be noted that compared with lighter small molecules, heavier macromolecular particles will produce stronger acceleration under the suction of strong winds, thus achieving the separation of macromolecular particle pollutants; for example, when winnowing wheat, the wheat will be thrown far away and the husks will float to the other side, thus achieving the separation of wheat and husks.

[0035] In one embodiment, a windshield 8 is provided between the indoor return air chamber 3 and the exhaust air chamber 2, an exhaust air inlet 9 is formed between the windshield 8 and the filter screen 7, and the exhaust air inlet 9 is connected to the exhaust air chamber 2. The windshield 8 can guide the airflow of the indoor return air chamber 3 and condense and adsorb it, so that part of the airflow (containing large molecular particle pollutants) in the indoor return air chamber 3 either flows upward through the windshield 8 into the exhaust air inlet 9 and enters the exhaust air chamber 2 through the exhaust air inlet 9, or condenses and flows down into the sewage tank 11 under the action of gravity.

[0036] In one embodiment, the wind shield 8 and the filter screen 7 form an eight-shaped structure so that large molecular particle pollutants can be more easily sucked and circulated.

[0037] In one embodiment, a sewage trough 11 is provided between the wind shield 8 and the indoor return air outlet 31 to store residual pollutants.

[0038] The drain chute 11 is detachably connected between the wind shield 8 and the indoor return air outlet 31 for easy disassembly and cleaning.

[0039] For easy observation, the sewage trough 11 may be made of a transparent material.

[0040] In one of the embodiments, an air guide grille 10 is further provided on one side of the filter screen 7 close to the indoor return air chamber 3 to better guide the macromolecular drift flow toward the exhaust chamber 2 .

[0041] Furthermore, the air guide grille 10 includes a plurality of corrugated portions 101 in a corrugated shape.

[0042] Specifically, the above-mentioned corrugated portion 101 can be in an inverted S shape, that is: the inner arc surface of the upper arc surface in the inverted S-shaped structure faces the outdoor sewage discharge side, and the outer arc surface of the lower arc surface of the inverted S-shaped structure faces the outdoor sewage discharge side. Large molecular drifting objects hit the outer arc surface and are accelerated and lifted up. When passing through the inner arc surface, they are thrown out along the open inner arc surface to better guide the large molecular drifting flow to the exhaust side.

[0043] In one embodiment, the rotating shaft of the supply fan 6 and the rotating shaft of the exhaust fan 5 are connected through a gear transmission mechanism, and the rotating shaft of the supply fan 6 is driven to rotate by the driving motor 12. The rotation of the rotating shaft of the supply fan 6 will drive the supply fan 6 to rotate, and the rotation of the rotating shaft of the exhaust fan 5 will drive the exhaust fan 5 to rotate.

[0044] The gear transmission mechanism can be used to change the speed, thereby increasing the rotation speed and suction of the exhaust fan 5, so that a suction difference is generated between the indoor air supply side and the outdoor air exhaust side, thereby better achieving the effect of separating drifting pollutants.

[0045] Furthermore, the gear transmission structure includes a driving gear 14 and a driven gear 15, the driving gear 14 is connected to the rotating shaft of the supply fan 6, the driven gear 15 is connected to the main shaft of the exhaust fan 5, and the driving gear 14 and the driven gear teeth are meshed through an intermediate gear 16; wherein the rotation speed of the driven gear 15 is greater than the rotation speed of the driving gear 14.

[0046] The above mechanism can better control the transmission ratio, thereby better controlling the speed difference between the supply fan 6 and the exhaust fan 5 .

[0047] It can be understood that the gear transmission mechanism further includes a speed change gear box 13 , in which the driving gear 14 , the driven gear 15 and the intermediate gear 16 are all arranged.

[0048] In one embodiment, if Figure 1-Figure 3 As shown, an upper foam member 17 and a lower foam member 18 are arranged in the housing 1, and an exhaust cavity 2 is formed between the upper foam member 17 and the lower foam member 18. The upper foam member 17 and the lower foam member 18 are both products made of foam material.

[0049] The foam element has good thermal insulation effect, and can effectively reduce the heat exchange between the exhaust cavity 2 and the outside, so that the dirty air can pass through better, and the pollutants will not be retained and condensed here due to temperature changes.

[0050] In one embodiment, a condenser 20 is connected to the lower foam member 18 so that the macromolecular particle pollutants can be more easily adsorbed and condensed on the side of the drain tank 11, thereby better separating the macromolecular particle pollutants.

[0051] Furthermore, the condenser 20 can be integrally formed with the lower foam member 18, that is, when the lower foam member 18 is formed, the condenser 20 is put into the mold together and foamed integrally, and after forming, the condenser 20 is integrated with the foam member.

[0052] In one embodiment, an air inlet grille 19 is provided at the indoor return air outlet 31 .

[0053] In one embodiment, if Figure 3 As shown, the housing 1 is mainly assembled from a lower cover plate 21 , an upper cover plate 22 , a left cover plate 23 and a right cover plate 24 .

[0054] The kitchen and bathroom air conditioner return air structure of the above-mentioned embodiment can separate the pollutants in the special space as much as possible and directly discharge them outdoors, thereby effectively reducing the difficulty of cleaning the air conditioner in this special space.

[0055] The return air structure of the kitchen and bathroom air conditioner in the above-mentioned embodiment can separate the oil smoke and water vapor to the maximum extent and discharge them outdoors, thereby optimizing and reducing the filtering load of the indoor air supply filter, effectively reducing the cleaning frequency of the kitchen and bathroom air conditioner filter, and is particularly suitable for use in spaces with serious pollutants such as kitchens / bathrooms. It can effectively improve the service life of the air conditioner, better expand the use places of the air conditioner, and improve people's physical comfort in different places.

[0056] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
