[0034] like Figures 1 to 3 As shown, in some embodiments of the air conditioner provided by the present invention, the air conditioner includes a shell 1, a heat exchanger 2, a filter device 3 and a deodorizing device 4. The shell 1 is provided with a return air port 101 and an air supply port 102. The heat exchanger 2 is arranged inside the shell 1. The heat exchanger 2 is configured to cool the return air entering the shell 1. The filter device 3 is arranged inside the shell 1. The filter device 3 is configured to filter the return air entering the shell 1. The deodorizing device 4 is arranged inside the shell 1. The deodorizing device 4 is configured to reduce the odor of the return air entering the shell 1.

[0035] In the above embodiment, by providing a filter device 3, the return air entering the shell can be filtered, the dust in the air-conditioning supply air can be reduced, and the cleanliness of the air-conditioning supply air can be improved; by providing a deodorization device 4, the return air in the shell can be deodorized, the odor of the air-conditioning supply air can be reduced, and the freshness of the air-conditioning supply air can be improved; moreover, the filter device 3 and the deodorization device 4 are both provided inside the shell 1, which is conducive to simplifying the overall structure of the air conditioner and optimizing the layout.

[0036] In some embodiments, the filtering device 3 is disposed upstream of the deodorizing device 4 , and the heat exchanger 2 is disposed downstream of the deodorizing device 4 .

[0037] By arranging the filtering device 3 upstream of the deodorizing device 4, deodorization can be performed after the return air is filtered, thereby reducing the influence of dust and the like in the return air on the deodorization effect.

[0038] By placing the heat exchanger 2 downstream of the filter device 3 and the deodorization device 4, the return air can be filtered and deodorized and then cooled by the heat exchanger 2 to avoid dust or odor molecules in the return air affecting the heat exchange effect of the heat exchanger 2.

[0039] In some embodiments, the filtering device 3 includes a first filter 31 and a second filter 32, the second filter 32 is arranged downstream of the first filter 31, and the first filter 31 and the second filter 32 are configured to make the maximum size of the mixture passing through the second filter 32 smaller than the maximum size of the mixture passing through the first filter 31.

[0040] By providing the first filter 31 and the second filter 32 , the return air can be filtered at least twice, thereby effectively improving the filtering effect.

[0041] By making the maximum size of the mixture passing through the second filter 32 smaller than the maximum size of the mixture passing through the first filter 31 , the return air can be further filtered by the second filter 32 to filter out fine particles that the first filter 31 fails to filter out.

[0042] There are many options for the structure of the first filter 31 and the second filter 32, which will not be described in detail here. The structures of the first filter 31 and the second filter 32 can be the same or different.

[0043] In some embodiments, the first filter 31 includes a filter mesh having a plurality of filter holes formed therein.

[0044] In some embodiments, the second filter 32 includes multiple bags arranged vertically. The bags can be of the same or different sizes. The bags are provided with adsorbent particles that filter and adsorb gases. The adsorption pores formed by the particles in the bags have a diameter smaller than the filtration pores in the first filter 31.

[0045] In some embodiments, the filter device 3 further includes a mounting plate 33 , and the first filter 31 and the second filter 32 are respectively mounted on both sides of the mounting plate 33 .

[0046] By setting up a mounting plate 33 and installing the first filter 31 and the second filter 32 on both sides of the mounting plate 33 respectively, the distance between the first filter 31 and the second filter 32 can be effectively shortened, the overall occupied space of the filter device 3 can be reduced, the compactness of the internal structure of the air conditioner can be improved, and the wind resistance can be reduced, thereby reducing the energy consumption of the air conditioner.

[0047] In some embodiments, the mounting plate 33 is made of metal material, and the first filter 31 and the second filter 32 are respectively mounted on both sides of the mounting plate 33 by magnetic attraction.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, the deodorizing device 4 includes a mounting frame 41, a rosette filler 42 and a nozzle 43, the rosette filler 42 is arranged inside the mounting frame 41, and the nozzle 43 is installed on the top of the mounting frame 41 and is located inside the mounting frame 41.

[0049] By providing the mounting frame 41, it can be used to place the garland filler 42. The mounting frame 41 adopts a frame structure, which can form a storage space for the garland filler 42 and increase the air permeability to facilitate the return air in and out.

[0050] By installing the nozzle 43 on the top of the mounting frame 41, the spray liquid sprayed by the nozzle 43 can fall from top to bottom and contact the return air during the falling process, thereby removing the odor in the return air.

[0051] By arranging the nozzle 43 inside the mounting frame 41, the spray liquid sprayed by the nozzle 43 can be prevented from being sprayed outside the mounting frame 41, causing waste of the spray liquid and wetting other components in the shell 1, causing damage to other components or affecting the functions of other components.

[0052] Rosette packing 42 features high porosity, resistance to clogging, high flux, and low resistance, with high liquid retention in the gaps between the packings. By providing rosette packing 42, liquid sprayed from nozzle 43 remains on the packing for a longer period of time, thereby increasing the contact time between gas and liquid and improving deodorization efficiency.

[0053] like Figure 5 As shown, the rosette filler 42 can be spherical. The rosette filler 42 includes a plurality of branches and a plurality of intersections, and a plurality of ridges or grooves can be provided on the branches to extend the residence time of the liquid.

[0054] The number of the rosette filler 42 and the number of the nozzle 43 can be one or more.

[0055] like Figure 5 As shown, a plurality of rosette fillers 42 are arranged in the mounting frame 41. The sizes of the plurality of rosette fillers 42 can be the same or different. A plurality of nozzles 43 are arranged at intervals on the top of the mounting frame 41.

[0056] In some embodiments, the deodorizing device 4 further includes a water tank 44 . The bottom of the mounting frame 41 is disposed in the water tank 44 . The water tank 44 is configured to receive the spraying liquid sprayed by the spray head 43 .

[0057] By setting up a water tank 44 and setting the bottom of the mounting frame 41 in the water tank 44, the spray liquid sprayed by the nozzle 43 can be received through the water tank 44, so that the spray liquid sprayed by the nozzle 43 can be collected and discharged uniformly, preventing the spray liquid from flowing to other parts of the shell 1 and affecting the normal operation of other components.

[0058] The air conditioner may include a first delivery pipe communicating with the spray head 43 to deliver the spray liquid, and the spray liquid is sprayed from the spray head 43 onto the rosette filler 42.

[0059] The air conditioner may further include a second delivery pipe in communication with the water tank 44 so as to discharge the liquid collected in the water tank 44 .

[0060] In some embodiments, the deodorizing device 4 further includes a switch valve disposed on the nozzle 43 , the switch valve is connected to a controller signal, and the controller opens or closes the deodorizing device 4 by controlling the opening and closing of the switch valve.

[0061] In some embodiments, the controller is connected to the air conditioner's power button signal, and the controller starts and stops the air conditioner via the power button. The controller is also configured to synchronize the start and stop of the air conditioner with the opening and closing of the deodorizing device 4, so that the deodorizing device 4 is activated when the air conditioner is turned on and is deactivated when the air conditioner is turned off. This not only allows for timely deodorization, but also saves energy.

[0062] In some embodiments, an exhaust chamber 11 connected to the return air port 101 is provided in the shell 1, and the exhaust chamber 11 is arranged upstream of the filter device 3. The air conditioner also includes a first regulating valve 12 and a second regulating valve 13 arranged in the exhaust chamber 11. The first regulating valve 12 is configured to adjust the return air flow discharged from the exhaust chamber 11 to the outdoor environment, and the second regulating valve 13 is configured to adjust the return air flow discharged from the exhaust chamber 11 into the space in the shell 1 downstream of the exhaust chamber 11.

[0063] By providing the exhaust chamber 11, the direction and flow rate of the exhaust air can be adjusted as needed. For example, the first regulating valve 12 can be used to adjust the flow rate of the return air discharged from the exhaust chamber 11 to the outdoor environment; and the second regulating valve 13 can be used to adjust the flow rate of the return air discharged from the exhaust chamber 11 into the space within the housing 1 located downstream of the exhaust chamber 11.

[0064] Through the first regulating valve 12 and the second regulating valve 13 , the return air in the exhaust chamber 11 can be discharged into the external environment or into the space in the housing 1 downstream of the exhaust chamber 11 as needed.

[0065] In some embodiments, the housing 1 is provided with a third regulating valve 14 , which is configured to regulate the flow rate of fresh air delivered into the housing 1 .

[0066] By providing the third regulating valve 14 , the flow rate of the fresh air sent into the casing 1 can be adjusted.

[0067] The air conditioner may further include a third delivery pipe for delivering fresh air so as to discharge outdoor fresh air into the interior of the housing 1 .

[0068] In an embodiment in which a first regulating valve 12, a second regulating valve 13 and a third regulating valve 14 are provided at the same time, the return air and the fresh air can be mixed in different proportions by controlling the first regulating valve 12, the second regulating valve 13 and the third regulating valve 14, so that the air-conditioning supply contains return air and fresh air in different proportions, and a part of the fresh air is used to replace the return air, thereby improving the quality of the air-conditioning supply.

[0069] In some embodiments, the air conditioner further includes a water retaining device 5 disposed downstream of the heat exchanger 2 , the water retaining device 5 being configured to block the flow of the airflow cooled by the heat exchanger 2 and to separate the airflow into gas and liquid on the retaining surface of the water retaining device 5 .

[0070] By setting up the water retaining device 5, the flow of the air flow after being cooled by the heat exchanger 2 can be blocked, and the air flow can be separated into gas and liquid on the blocking surface of the water retaining device 5, thereby reducing the water content in the air-conditioning supply and improving the comfort of the person using the air conditioner.

[0071] like Figure 6As shown, in some embodiments, the water retaining device 5 includes a first support plate 51 and a plurality of water retaining plates 52, and the plurality of water retaining plates 52 are installed on the first support plate 51 at intervals. The water retaining plates 52 include a first blocking surface 521 and a second blocking surface 522, and the first blocking surface 521 and the second blocking surface 522 are both arranged at an angle relative to the air outlet surface of the heat exchanger 2, and the first blocking surface 521 and the second blocking surface 522 are connected to form a V-shaped structure.

[0072] By providing the first blocking surface 521 , the flow of the cooled airflow can be blocked, and at the same time, the airflow can be separated into gas and liquid at the first blocking surface 521 , thereby reducing the water content in the airflow.

[0073] By connecting the first blocking surface 521 and the second blocking surface 522 to form a V-shaped structure, the airflow can be turned and flow out along the back of the second blocking surface 522 after being blocked and separated from the gas and liquid by the first blocking surface 521; at the same time, since multiple water baffles 52 are arranged at intervals on the first support plate 51, there is a gap between the two adjacent water baffles 52, and the airflow can flow out through the gap between the two adjacent water baffles 52, and after the first blocking surface 521 of one of the water baffles 52 blocks the airflow and separates the gas and liquid, the airflow can be blocked again and separated from the gas and liquid again by the second blocking surface 522 of the other water baffle 52 after continuing to flow, thereby greatly improving the blocking and gas-liquid separation effects.

[0074] The plurality of water retaining plates 52 are arranged at intervals on the first support plate 51 , and can also form a flow balancing and stabilizing effect on the airflow, so that the airflow after passing through the water retaining device 5 flows more evenly and smoothly.

[0075] The first blocking surface 521 and the second blocking surface 522 are arranged to be inclined relative to the air outlet surface of the heat exchanger 2, which can achieve the blocking and gas-liquid separation effects without affecting the continued flow of the airflow downstream.

[0076] The first blocking surface 521 and the second blocking surface 522 may be inclined at an acute angle or an obtuse angle relative to the air outlet surface of the heat exchanger 2 .

[0077] It should be understood that the first blocking surface 521 and the second blocking surface 522 are non-perpendicular to the air outlet surface of the heat exchanger 2. Because when the first blocking surface 521 is perpendicular to the air outlet surface of the heat exchanger 2 and the second blocking surface 522 is perpendicular to the air outlet surface of the heat exchanger 2, the first blocking surface 521 and the second blocking surface 522 are basically unable to block the flow of airflow, and the gas-liquid separation effect will also be reduced.

[0078] In some embodiments, the opening of the V-shaped structure on the water baffle 52 is parallel to the air outlet surface of the heat exchanger 2 , so that the first blocking surface 521 and the second blocking surface 522 are both inclined relative to the air outlet surface of the heat exchanger 2 .

[0079] In some embodiments, the air conditioner also includes a first motor 61, a first fan 62, a first support seat 63 and a first buffer member 64 arranged in the shell 1, the first motor 61 is configured to drive the first fan 62 to rotate, the first fan 62 is configured to drive return air into the shell 1, the first motor 61 and the first fan 62 are installed on the first support seat 63, and the first buffer member 64 is installed between the first support seat 63 and the inner wall of the shell 1.

[0080] By installing the first motor 61 and the first fan 62 on the same first support base 63, and installing the first support base 63 on the inner wall of the shell 1 through the first buffer member 64, the impact of the shaking of the first motor 61 and the first fan 62 during operation on the shell 1 can be effectively reduced, and the impact of the shaking of the first motor 61 and the first fan 62 on other components inside the shell 1 can be reduced, and noise can also be reduced.

[0081] The first buffer member 64 can be a damping member or an elastic member.

[0082] In some embodiments, the air conditioner also includes a second motor 71, a second fan 72, a second support seat 73 and a second buffer member 74 arranged in the shell 1, the second motor 71 is configured to drive the second fan 72 to rotate, and the second fan 72 is configured to drive the airflow in the shell 1 to discharge outside the shell 1, the second motor 71 and the second fan 72 are installed on the second support seat 73, and the second buffer member 74 is installed between the second support seat 73 and the inner wall of the shell 1.

[0083] By installing the second motor 71 and the second fan 72 on the same second support base 73 and installing the second support base 73 on the inner wall of the shell 1 through the second buffer member 74, the impact of the shaking of the second motor 71 and the second fan 72 during operation on the shell 1 can be effectively reduced, and the impact of the shaking of the second motor 71 and the second fan 72 on other components inside the shell 1 can be reduced, and the noise can also be reduced.

[0084] The second buffer member 74 can be a damping member or an elastic member.
