[0026] This invention proposes an air conditioner.

[0027] Please see Figures 11 to 16This invention proposes an air conditioner 100 for outdoor installation. The air conditioner 100 has a first air vent 100a and a second air vent 100b, both of which are connected to the indoor environment. The air intake and exhaust device 160 includes a housing 161 and a guide slider 165. The housing 161 has a first ventilation opening 162 communicating with the first air outlet 100a, a second ventilation opening 163 communicating with the second air outlet 100b, and a third ventilation opening 164 communicating with the outside. The guide slider 165 has a guide channel 166. The guide slider 165 is movably installed in the housing 161 and has a first position and a second position. When the guide slider 165 is in the first position, the guide channel 166 connects the first ventilation opening 162 and the second ventilation opening 163. When the guide slider 165 is in the second position, the guide channel 166 connects the first ventilation opening 162 or the second ventilation opening 163 and the third ventilation opening 164.

[0028] Specifically, the air conditioner 100 has a first air vent 100a and a second air vent 100b communicating with the indoor environment. One of the first air vent 100a and the second air vent 100b is an air intake vent, and the other is an air exhaust vent. The number and shape of the first air vent 100a and the second air vent 100b are not specifically limited. For example, the number of the first air vent 100a and the second air vent 100b can be one, two, or more, and can be selected and designed according to actual usage. The shape of the first air vent 100a and the second air vent 100b can be circular, elliptical, square, or other irregular shapes. Furthermore, the first air vent 100a can be located above or below the second air vent 100b. Of course, the first air vent 100a can also be at the same height as the second air vent 100b, which is also not specifically limited. For ease of description, the following description will take the example of the first air vent 100a being located above the second air vent 100b.

[0029] In this embodiment of the invention, by providing an air intake and exhaust device 160 in the flow path between the first air outlet 100a and the second air outlet 100b, it is possible to draw in fresh outdoor air or exhaust stale indoor air, thereby improving indoor air quality and enhancing user comfort. Specifically, the air intake and exhaust device 160 includes a housing 161 and a guide slider 165. An air cavity is formed inside the housing 161, and the guide slider 165 is movably installed within the air cavity. The guide slider 165 can be slidably installed within the air cavity, or it can be rotatably installed within the air cavity, depending on actual needs. The guide slider 165 has an air guide channel 166, which can include two sub-channels, or it can be a single large channel; no specific limitation is made. When the air guide slider 165 moves to the first position, the air guide channel 166 connects the first vent 162 and the second vent 163. At this time, indoor air is drawn in from one of the first vent 100a and the second vent 100b, and flows out of the room from the other vent, thus achieving indoor air circulation. When the air guide slider 165 moves to the second position, the air guide channel 166 connects the first vent 162 or the second vent 163 and the third vent 164. At this time, indoor air can flow into the room from the first vent 100a or the second vent 100b, and flow out of the room from the third vent 164, thus achieving the removal of stale indoor air; or outdoor air can flow in from the third vent 164, and flow out of the room from the first vent 100a or the second vent 100b, thus achieving the intake of fresh outdoor air. Therefore, by moving the air guide slider 165, fresh outdoor air can be drawn in or stale indoor air can be expelled, thereby improving indoor air quality and enhancing user comfort.

[0030] In addition, in this embodiment of the invention, the air conditioner 100 further includes a fan 120 and a heat exchanger 150. The fan 120 and the heat exchanger 150 are installed in the flow path between the first air outlet 100a and the second air outlet 100b. This minimizes the indoor space occupied by the air conditioner 100 and avoids the need for drainage pipes to discharge condensate. Of course, it is understood that in other embodiments, the fan 120 or the heat exchanger 150 may also be installed indoors, without specific limitation.

[0031] The air conditioner 100 of the present invention is designed for outdoor installation, thereby reducing its impact on indoor space. The air conditioner 100 has a first air vent 100a and a second air vent 100b, both of which communicate with the indoor environment. The air conditioner 100 includes an air intake / exhaust device 160 installed in the flow path between the first air vent 100a and the second air vent 100b. The air intake / exhaust device 160 includes a housing 161 and a guide slider 165. The housing 161 has a first ventilation opening 162 communicating with the first air vent 100a, a second ventilation opening 163 communicating with the second air vent 100b, and a third ventilation opening 164 communicating with the outdoors. The guide slider 165 has an air guide channel 166. The guide slider 165 is movably installed within the housing 161 and has a first position and a second position. When the guide slider 165 is in the first position, the air guide channel 166 communicates with the first ventilation opening 100a. When the first vent 100a and the second vent 163 are connected, indoor air is drawn in from one of the first vent 100a and the second vent 100b and flows out of the room from the other vent, thus achieving indoor circulation. When the air guide slider 165 is in the second position, the air guide channel 166 connects the second vent 163 and the third vent 164. At this time, indoor air can flow into the room from the first vent 100a or the second vent 100b and flow out of the room from the third vent 164, thus achieving the exhaust of indoor stale air; or outdoor air can flow into the room from the third vent 164 and flow out of the room from the first vent 100a or the second vent 100b, thus achieving the intake of outdoor fresh air. In this way, by setting the air intake and exhaust device 160, outdoor fresh air can be drawn in and indoor stale air can be exhausted, thereby effectively improving indoor air quality and improving user comfort.

[0032] Please see Figure 11 and Figure 12 In one embodiment, the second vent 163 is disposed opposite to the first vent 162, and the third vent 164 is disposed offset from the first vent 162. The air guide channel 166 includes a first channel 167 and a second channel 168. When the air guide slider 165 is in a first position, the first channel 167 connects the first vent 162 and the second vent 163; when the air guide slider 165 is in a second position, the second channel 168 connects the first vent 162 or the second vent 163 and the third vent 164. Specifically, the first channel 167 and the second channel 168 are disposed adjacent to each other, the first channel 167 is a straight channel, and the second channel 168 is an arc-shaped channel.

[0033] Furthermore, the air conditioner 100 also includes a first driving device 170, which is used to drive the air guide slider 165 to move between the first position and the second position.

[0034] There are various structures and driving methods for the first driving device 170. For example, the first driving device 170 includes a driving component and a gear and rack transmission assembly, wherein the driving component drives the air guide slider 165 to move through the gear and rack transmission assembly. Another example is that the first driving device 170 includes a driving component and a crank-connecting rod assembly, wherein the driving component drives the air guide slider 165 to move through the crank-connecting rod assembly. Yet another example is that the first driving device 170 further includes a driving component and a transmission belt assembly, wherein the driving component drives the air guide slider 165 to move through the transmission belt assembly.

[0035] In addition, in order to ensure that the air guide slider 165 moves along a predetermined trajectory, a groove 169 can be provided on the housing 161, and a slide rail adapted to the groove 169 can be provided on the air guide slider 165, with the slide rail slidingly engaging with the groove 169.

[0036] Please see Figures 14 to 16 In one embodiment, the air conditioner 100 includes a housing 110, which is installed in the flow path between the first air vent 100a and the second air vent 100b. The housing 110 is provided with a first connecting port 111 connecting the first air vent 100a and a second connecting port 112 connecting the second air vent 100b. The fan 120 is installed inside the housing 110.

[0037] In this embodiment, the outer casing 110 is generally cuboid in shape, but is not limited thereto. The upper side of the outer casing 110 has a first connecting port 111 that communicates with the first air vent 100a, and the lower side of the outer casing 110 has a second connecting port 112 that communicates with the second air vent 100b. The first connecting port 111 is connected to the first air vent 100a via a ventilation duct, and the second connecting port 112 is connected to the second air vent 100b via a ventilation duct.

[0038] It should be noted that the air intake and exhaust device 160 can be located on the upper and / or lower side of the outer casing 110. If the air intake and exhaust device 160 is located on the upper side of the outer casing 110, then the first vent 162 is connected to the first air outlet 100a, the second vent 163 is connected to the first connecting port 111, and the third vent 164 is connected to the outside. Thus, when the air guide slider 165 is in the first position, the air guide channel 166 connects the first vent 162 and the second vent 163; when the air guide slider 165 is in the second position, the air guide channel 166 connects the second vent 163 and the third vent 164.

[0039] If the air intake and exhaust device 160 is located on the lower side of the housing 110, then the first vent 162 is connected to the second vent 100b, the second vent 163 is connected to the second connecting port 112, and the third vent 164 is connected to the outside. Thus, when the air guide slider 165 is in the first position, the air guide channel 166 connects the first vent 162 and the second vent 163; when the air guide slider 165 is in the second position, the air guide channel 166 connects the first vent 162 and the third vent.

[0040] The number of the suction and exhaust devices 160 can be one or two. If there is only one suction and exhaust device 160, it can be located on the upper or lower side of the outer casing 110; if there are two suction and exhaust devices 160, they are respectively located on the upper and lower sides of the outer casing 110 (e.g., ...). Figure 18 and Figure 19 (As shown). The following description will take the case where the air intake and exhaust device 160 is located on the upper side of the outer casing 110 as an example.

[0041] Please see Figures 1 to 8 In one embodiment, the air conditioner 100 further includes a reversing assembly 130, which is installed in the flow path between the first air vent 100a and the second air vent 100b. The air conditioner 100 has a first operating mode and a second operating mode. In the first operating mode, the reversing assembly 130 allows indoor air to enter through the first air vent 100a and exit through the second air vent 100b; in the second operating mode, the reversing assembly 130 allows indoor air to enter through the second air vent 100b and exit through the first air vent 100a.

[0042] In this embodiment, the reversing component 130 can control one of the first air vent 100a and the second air vent 100b to be an air intake and the other to be an air exhaust vent. That is, the reversing component 130 mainly functions to change the direction of airflow. Here, the air conditioner 100 includes a first operating mode and a second operating mode, where the airflow direction differs between the first and second operating modes. No specific limitations are made regarding the first and second operating modes. For example, but not limited to, in this embodiment, the first operating mode is a heating mode. In this mode, the reversing component 130 causes indoor air to enter through the upper first air vent 100a and exit through the lower second air vent 100b, thereby blowing hot air downwards into the room, achieving a warming effect on the feet and improving user comfort. The second operating mode is the cooling mode. In this mode, the reversing component 130 causes indoor air to enter through the second air vent 100b below and be blown out through the first air vent 100a above, thereby blowing cold air into the upper part of the room, achieving the effect of avoiding cold air blowing on people and improving the user's comfort.

[0043] In this embodiment, by installing the reversing component 130 in the flow path between the first air vent 100a and the second air vent 100b, in the first operating mode, the reversing component 130 allows indoor air to enter through the first air vent 100a and exit through the second air vent 100b; in the second operating mode, the reversing component 130 allows indoor air to enter through the second air vent 100b and exit through the first air vent 100a. Thus, when the user selects the first or second operating mode according to actual usage needs, the reversing component 130 can switch the positions of the air inlet 121 and the air outlet 122, thereby achieving the effect of preventing cold air from blowing on people and ensuring warm air reaches the ground, effectively improving the user comfort of the air conditioner 100.

[0044] Specifically, in the first operating mode, the reversing component 130 connects the first connecting port 111 to the air inlet 121 of the fan 120, and connects the second connecting port 112 to the air outlet 122 of the fan 120; thus, indoor air enters through the first air outlet 100a and exits through the second air outlet 100b. In the second operating mode, the reversing component 130 connects the second connecting port 112 to the air inlet 121 of the fan 120, and connects the first connecting port 111 to the air outlet 122 of the fan 120; thus, indoor air enters through the second air outlet 100b and exits through the first air outlet 100a.

[0045] Please see Figures 4 to 7In one embodiment, the reversing assembly 130 includes a first reversing device 131 and a second reversing device 135. Both the first reversing device 131 and the second reversing device 135 are disposed within the housing 110, with the first reversing device 131 positioned near the first connecting port 111 and the second reversing device 135 positioned near the second connecting port 112. The first reversing device 131 serves to connect the first connecting port 111 to the air outlet 122 of the fan 120, and also serves to close the air outlet 122 of the fan 120 and open the first connecting port 111, thus connecting the first connecting port 111 to the air inlet 121 of the fan 120. The second reversing device 135 can connect the second connecting port 112 with the air outlet 122 of the fan 120, and can also close the air outlet 122 of the fan 120 and open the second connecting port 112, so that the second connecting port 112 can be connected with the air inlet 121 of the fan 120.

[0046] In this embodiment, in the first operating mode, the first reversing device 131 connects the first connecting port 111 to the air inlet 121 of the fan 120, and the second reversing device 135 connects the second connecting port 112 to the air outlet 122 of the fan 120. Thus, indoor air enters through the first air vent 100a, flows into the outer casing 110 through the first connecting port 111, enters the air inlet 121 of the fan 120, and finally flows from the air outlet 122 of the fan 120 to the second connecting port 112, and is finally blown into the room through the second air vent 100b. In the second operating mode, the first reversing device 131 connects the first connecting port 111 to the air outlet 122 of the fan 120, and the second reversing device 135 connects the second connecting port 112 to the air inlet 121 of the fan 120. In this way, indoor air enters through the second air vent 100b, flows into the outer casing 110 through the second connecting port 112 and enters the air inlet 121 of the fan 120, and finally flows from the air outlet 122 of the fan 120 to the first connecting port 111, and is finally blown into the room through the first air vent 100a.

[0047] Please see Figures 4 to 7The fan 120 is a centrifugal fan 120. The centrifugal fan 120 can be a single-inlet centrifugal fan 120 or a double-inlet centrifugal fan 120. If the fan 120 is a single-inlet centrifugal fan 120, it has one air inlet 121; if the fan 120 is a double-inlet centrifugal fan 120, it has two opposing air inlets 121. Additionally, the fan 120 has two air outlets 122, namely a first air outlet 1221 and a second air outlet 1222. The first air outlet 1221 is opposite to the first connecting port 111, and the second air outlet 1222 is opposite to the second connecting port 112. Specifically, the first air outlet 1221 and the second air outlet 1222 are arranged radially along the fan 120.

[0048] The structure of the first commutator 131 and the second commutator 135 will be described below.

[0049] Please see Figures 4 to 7 In one embodiment, the first reversing device 131 has a first switching state and a second switching state. In the first switching state, the first reversing device 131 connects the first connecting port 111 with the first air outlet 1221 of the fan 120. In the second switching state, the first reversing device 131 connects the first connecting port 111 with the air inlet 121 of the fan 120.

[0050] By switching the first reversing device 131 between the first switching state and the second switching state, the first connecting port 111 can be connected to the air inlet 121 of the fan 120, or the first connecting port 111 can be connected to the first air outlet 1221 of the fan 120, thereby changing the direction of airflow.

[0051] Specifically, such as Figure 7 As shown, the first reversing device 131 includes a first air guide section 132 and a first baffle section 134. The first air guide section 132 and the first baffle section 134 are arranged along the axial direction of the fan 120. The first air guide section 132 has a first air guide channel 133. In the first switching state, the first air guide channel 133 connects the first connecting port 111 and the first air outlet 1221 of the fan 120. In the second switching state, the first baffle section 134 closes the first air outlet 1221 of the fan 120 and opens the first connecting port 111. At this time, the first connecting port 111 connects to the air inlet 121 of the fan 120.

[0052] To facilitate switching between the first switching state and the second switching state, the first switching device 131 can move along the axial direction of the fan 120. Thus, when the first switching device 131 moves to the point where the first air guide channel 133 connects the first air outlet 1221 of the fan 120 with the first connecting port 111, the first switching device 131 switches to the first switching state; when the first switching device 131 moves to the point where the first baffle 134 closes the first air outlet 1221 of the fan 120 and opens the first connecting port 111, the first connecting port 111 connects with the air inlet 121 of the fan 120, and at this time, the first switching device 131 switches to the second switching state.

[0053] The second reversing device 135 has a third switching state and a fourth switching state. In the third switching state, the second reversing device 135 connects the second connecting port 112 with the second air outlet 1222 of the fan 120. In the fourth switching state, the second reversing device 135 connects the first connecting port 111 with the air inlet 121 of the fan 120.

[0054] By cooperating with the first reversing device 131, the second reversing device 135 switches between the third switching state and the fourth switching state, controlling the second connecting port 112 to connect with the air inlet 121 of the fan 120, or controlling the second connecting port 112 to connect with the second air outlet 1222 of the fan 120, thereby achieving the effect of changing the direction of airflow.

[0055] Specifically, such as Figure 7 As shown, the second reversing device 135 includes a second air guide section 136 and a second baffle section 138. The second air guide section 136 and the second baffle section 138 are arranged along the axial direction of the fan 120. The second air guide section 136 has a second air guide channel 137. In the third switching state, the second air guide channel 137 connects the second connecting port 112 and the second air outlet 1222 of the fan 120. In the fourth switching state, the second baffle section 138 closes the second air outlet 1222 of the fan 120 and opens the second connecting port 112.

[0056] In the first operating mode, the first reversing device 131 is in the second switching state, and the second reversing device 135 is in the third reversing state. That is, the first baffle 134 closes the first air outlet 1221 and opens the first connecting port 111. The second air guide channel 137 connects the second connecting port 111 and the second air outlet 1222. In this way, indoor air enters through the second air vent 100b, further flows into the air inlet 121 of the fan 120, and then flows from the first air outlet 1221 to the second air vent 100b, and is blown out through the second air vent 100b.

[0057] In the second operating mode, the first reversing device 131 is in the first switching state, and the second reversing device 135 is in the fourth reversing state. That is, the first air guide channel 133 connects the first connecting port 111 and the first air outlet 1221; the second baffle 138 closes the second air outlet 1222 and opens the second connecting port 112, so that indoor air enters from the second air vent 100b, further flows into the air inlet 121 of the fan 120, and then flows from the first air outlet 1221 to the first air outlet 100a, and is blown out from the first air outlet 100a.

[0058] To facilitate switching between the third and fourth switching states, the second reversing device 135 is movable along the axial direction of the fan 120. Thus, when the second reversing device 135 moves to the point where the second air guide channel 137 connects the second air outlet 1222 of the fan 120 with the second connecting port 112, the second reversing device 135 switches to the third switching state; when the second reversing device 135 moves to the point where the second stop 138 closes the second air outlet 1222 of the fan 120 and opens the second connecting port 112, the second connecting port 112 connects with the air inlet 121 of the fan 120, and at this time, the second reversing device 135 switches to the fourth switching state.

[0059] Furthermore, to better drive the first commutator 131 and the second commutator 135, the air conditioner 100 may also include a second drive device 140, which drives the first commutator 131 and / or the second commutator 135 to move. It should be noted that the second drive device 140 can drive the first commutator 131 and the second commutator 135 to move separately, or it can drive both the first commutator 131 and the second commutator 135 to move simultaneously. That is, the number of second drive devices 140 can be one or two, without specific limitation.

[0060] The structure and driving method of the second driving device 140 can be varied. For example, please refer to... Figure 9 and Figure 10 In one embodiment, the second drive device 140 includes a drive motor 141, a first pulley 144, a second pulley 145, and a transmission belt 146. The transmission belt 146 drives the first pulley 144 to rotate and the second pulley 145 to rotate. The drive motor 141 drives the first pulley 144 to rotate and the second pulley 145 is connected to the first reversing device 131 or the second reversing device 135 through a crank mechanism 147.

[0061] In this embodiment, the drive motor 141 drives the first rotating wheel 144 to rotate, and the first rotating wheel 144 drives the second rotating wheel 145 to rotate via the transmission belt 146. The second rotating wheel 145 can drive the first reversing device 131 or the second reversing device 135 to move via the crank mechanism 147, thereby enabling the first reversing device 131 to switch between the first switching state and the second switching state, or the second reversing device 135 to switch between the third switching state and the fourth switching state.

[0062] Furthermore, in this embodiment, there are two second rollers 145 and two crank mechanisms 147. The two second rollers 145 are located on opposite sides of the first roller 144. One second roller 145 is connected to the first reversing device 131 via the crank mechanism 147, and the other second roller 145 is connected to the second reversing device 135 via the crank mechanism 147. Thus, one second roller 145 can drive the first reversing device 131 to switch between a first switching state and a second switching state, and the other second roller 145 can drive the second reversing device 135 to switch between a third switching state and a fourth switching state, thereby achieving the effect of simultaneously driving both the first reversing device 131 and the second reversing device 135.

[0063] Specifically, the crank mechanism 147 includes a crank 1471 and a connecting rod 1473. The crank 1471 has a connecting portion 1472 protruding to one side. One end of the connecting rod 1473 is connected to the connecting portion 1472, and the other end is connected to the first reversing device 131 or the second reversing device 135. Thus, when the second wheel 145 rotates, it can drive the crank 1471 to rotate, thereby causing the connecting rod 1473 to swing, thereby achieving the effect of driving the first reversing device 131 or the second reversing device 135 to move. It should be noted that the first reversing device 131 and the second reversing device 135 move in opposite directions.

[0064] Please see Figure 6 In another embodiment, the second drive device 140 includes a drive motor 141, a gear 142 and a rack 143. The rack 143 extends along the axial direction of the fan 120 and is mounted on the first reversing device 131 or the second reversing device 135. The gear 142 is connected to the drive shaft of the drive motor 141 and meshes with the rack 143.

[0065] In this embodiment, the drive motor 141 drives the gear 142 to rotate, and the gear 142 meshes with the rack 143, thereby driving the first reversing device 131 to switch between the first switching state and the second switching state, or the second reversing device 135 to switch between the third switching state and the fourth switching state.

[0066] Referring to the figure, in one embodiment, the air conditioner 100 further includes a heat exchange assembly, which includes a heat exchanger 150. The heat exchanger 150 is disposed within the outer casing 110 and located on the air inlet side of the fan 120, for exchanging heat with the air flowing through the heat exchanger 150. Of course, in other embodiments, the heat exchanger 150 may also be disposed outside the outer casing 110, without specific limitation. As for the structure of the heat exchanger 150, there are various possibilities. For example, the heat exchanger 150 may be a flat plate structure, or it may be a V-shaped structure or a U-shaped structure, without specific limitation.

[0067] Please see Figure 20 and Figure 21 In order to allow air to be heated by the heat exchanger 150 before flowing into the air inlet 121 of the fan 120, the heat exchange assembly may also include a surrounding plate 154. The surrounding plate 154 and the heat exchanger 150 together form an air cavity. The fan 120 is installed in the air cavity, and at least a portion of the heat exchanger 150 is opposite to the air inlet 121 of the fan 120. In this way, the air entering the outer casing 110 will first be heated by the heat exchanger 150 before flowing into the air cavity, and then from the air cavity into the air inlet 121 of the fan 120.

[0068] Specifically, the heat exchanger 150 has a U-shaped structure and includes a first heat exchange section 151, a second heat exchange section 152, and a third heat exchange section 153. The third heat exchange section 153 connects the first heat exchange section 151 and the second heat exchange section 152. The first heat exchange section 151 is opposite to the air inlet 121 of the fan 120. To jointly construct an air cavity with the heat exchanger 150, the surrounding plate 154 includes a bottom plate 156, a side plate 157, and a top plate 155. The top plate 155 and the bottom plate 156 are respectively disposed on the upper and lower sides of the heat exchanger 150. The side plate 157 is disposed opposite to the third heat exchange section 153 and connects the first heat exchange section 151 and the second heat exchange section 152. Thus, the top plate 155, the bottom plate 156, the side plate 157, and the heat exchanger 150 jointly construct the air cavity.

[0069] Furthermore, to prevent condensate from flowing into the outer casing 110 from the heat exchanger 150, a water receiving tank 1561 can be provided on the base plate 156 to collect the condensate from the heat exchanger 150. In addition, a drain outlet is provided on the base plate 156 to drain the water in the water receiving tank 1561.

[0070] Please see Figure 20 and Figure 21 Considering that the fan 120 is mounted on the base plate 156, in order to prevent water in the water collection tank 1561 from flowing to the fan 120, the water collection tank 1561 can be made into an annular groove formed around the fan 120. In this way, by mounting the fan 120 inside the annular groove and the heat exchanger 150 inside the annular groove, condensate on the heat exchanger 150 can be collected, and condensate in the water collection tank 1561 can be prevented from flowing to the fan 120 and affecting its normal operation.

[0071] Based on the above embodiments, the air conditioner 100 has a fresh air mode and a waste air mode.

[0072] Please see Figure 15When the air conditioner 100 is in fresh air mode, the air guide slider 165 is in the second position, and the second channel 168 connects the second vent 163 and the third vent 164. At the same time, the first reversing device 131 is in the second switching state, and the first reversing device 131 connects the first connecting port 111 and the air inlet 121 of the fan 120. The second reversing device 135 is in the third switching state, and the second reversing device 135 connects the second connecting port 112 and the air outlet 122 of the fan 120. In this way, outdoor fresh air can enter the suction and exhaust device 160 from the third vent 164, and flow from the second channel 168 to the air inlet 121 of the fan 120, and finally flow from the second air outlet 1222 of the fan 120 to the second connecting port 112, and finally flow to the second air outlet 100b and be blown into the room from the second air outlet 100b, thereby introducing fresh air into the room.

[0073] Please see Figure 16 When the air conditioner 100 is in the exhaust mode, the air guide slider 165 is in the second position, and the second channel 168 connects the second vent 163 and the third vent 164. At the same time, the first reversing device 131 is in the first switching state, which connects the first connecting port 111 and the air outlet 122 of the fan 120. When the second reversing device 135 is in the fourth switching state, it connects the second connecting port 112 and the air inlet 121 of the fan 120. In this way, indoor air can enter from the second vent 100b, flow through the second connecting port 112 to the air inlet 121 of the fan 120, then flow from the first air outlet 1221 of the fan 120 to the first connecting port 111, and further flow into the suction and exhaust device 160, flow through the second channel 168 to the third vent 164, and finally be discharged outdoors through the third vent 164, thus achieving the effect of exhaust.

[0074] Based on the above embodiments, please refer to Figure 1 The air conditioner 100 also includes an air guide device 180, which is installed at the first air outlet 100a and / or the second air outlet 100b.

[0075] The air guiding device 180 primarily functions to guide airflow, directing indoor air towards the first air vent 100a or the second air vent 100b, and simultaneously guiding air from the first air vent 100a or the second air vent 100b into the room. The structure of the air guiding device 180 can vary considerably; for example, in one embodiment... Figure 22 and Figure 23As shown, the air guiding device 180 is an air guiding shroud 181, which can be cylindrical or square, without specific limitation. The air guiding shroud 181 is flared, resembling a horn structure. In another embodiment, as... Figure 24 and Figure 25 As shown, the air guiding device 180 includes an air guiding shell 182 and an air guiding plate 183. The air guiding shell 182 has an air guiding cavity and an inlet and an outlet communicating with the air guiding cavity. The inlet communicates with the first air outlet 100a or the second air outlet 100b. The air guiding plate 183 is rotatably mounted at the outlet to adjust the air outlet direction. The structure of the air guiding shell 182 can be various, such as cylindrical or cuboid, and is not specifically limited. In addition, there can be multiple outlets, which are arranged around the periphery of the air guiding shell 182, thus enabling air to be discharged in different directions, further increasing the air outlet range and air volume.

[0076] Based on the above embodiments, the second air vent 100b is located below the first air vent 100a, and the air conditioner 100 also includes a humidifying device 190, which is installed at the second air vent 100b, so as to facilitate the replenishment of water to the humidifying device 190.

[0077] Please see Figure 18 and Figure 19 In one embodiment, the humidification device 190 includes a humidification chamber 191, a water tank 192, and a wet film assembly 193. The water tank 192 is disposed inside the humidification chamber 191, and the wet film assembly 193 is movably installed inside the water tank 192, and has a humidification position for airflow to pass through and a retraction position for avoiding the airflow.

[0078] Specifically, when the wet film assembly 193 moves to the humidification position, air drawn in from or flowing towards the second air vent 100b can pass through the wet film assembly 193, thereby carrying away the water on the wet film assembly 193 and humidifying the air. When the wet film assembly 193 moves to the avoidance position, air drawn in from or flowing towards the second air vent 100b does not pass through the wet film assembly 193, thus eliminating the need for air humidification.

[0079] Please see Figure 17In one embodiment, an opening 1562 is formed in the base plate 156, and a valve 1563 is provided at the opening 1562 to open or close the opening 1562. Thus, when the valve 1563 is open, the air humidified by the humidification component can directly enter the air chamber through the opening 1562 and then flow directly into the air inlet 121 of the fan 120, thereby effectively preventing the air humidified by the wet film component 193 from being dried by the heat exchanger 150. When humidification of the air is not required, the valve 1563 can be closed.

[0080] There are several ways to connect the valve 1563 to the base plate 156. For example, the valve 1563 is rotatably connected to the base plate 156 to open or close the opening 1562; or the valve 1563 is slidably connected to the base plate 156 to open or close the opening 1562.

[0081] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
