[0027] Embodiment 1

[0028] An air conditioner 900 is proposed in an embodiment of the present invention, as Figures 1 to 12 shown, which includes a housing 100, a first blower assembly 200, a second blower assembly 400, and a heat exchange system having a first heat exchanger 610 and a second heat exchanger 620.

[0029] Inside the housing 100, a first chamber 170, a third chamber 150, and a second chamber 160 are sequentially arranged from left to right. On the left side wall of the first chamber 170, there is a first air inlet 110; on the front side wall, there is a first indoor air outlet 131; and on the rear side wall, there is a first outdoor air outlet 141. On the right side wall of the second chamber 160, there is a second air inlet 120; on the front side wall, there is a second indoor air outlet 132; and on the rear side wall, there is a second outdoor air outlet 142. The first fan assembly 200 is installed in the first chamber 170. The first fan assembly 200 has a first fan air inlet 210, a first fan sub-air outlet 220, and a second fan sub-air outlet 230. The second fan assembly 400 is installed in the second chamber 160. The second fan assembly 400 has a second fan air inlet 410, a third fan sub-air outlet 420, and a fourth fan sub-air outlet 430. The compressor 630 of the heat exchange system is installed in the third chamber 150, and the control device 180 is installed in the third chamber 150 and is located behind the compressor 630.

[0030] Among them, the first fan assembly 200 is fixed in the first chamber 170 of the housing 100. There is a first air inlet passage 310 between the first fan air inlet 210 and the first air inlet 110. There is a first indoor air outlet passage 320 between the first fan sub-air outlet 220 and the first indoor air outlet 131, and the first indoor air outlet passage 320 can be conducted and shut off. There is a first outdoor air outlet passage 330 between the second fan sub-air outlet 230 and the first outdoor air outlet 141, and the first outdoor air outlet passage 330 can be conducted and shut off. The first indoor air outlet passage 320 and the first outdoor air outlet passage 330 can be selectively conducted and selectively shut off.

[0031] The second fan assembly 400 is fixed in the second chamber 160 of the housing 100. There is a second air inlet passage 510 between the second fan air inlet 410 and the second air inlet 120. There is a second indoor air outlet passage 520 between the third fan sub-air outlet 420 and the second indoor air outlet 132, and the second indoor air outlet passage 520 can be conducted and shut off. There is a second outdoor air outlet passage 530 between the fourth fan sub-air outlet 430 and the second outdoor air outlet 142, and the second outdoor air outlet passage 530 can be conducted and shut off. Moreover, the second indoor air outlet passage 520 and the second outdoor air outlet passage 530 can be selectively conducted and selectively shut off.

[0032] The first heat exchanger 610 is fixed within the first air inlet passage 310, and the second heat exchanger 620 is fixed within the second air inlet passage 510. In some embodiments, the first heat exchanger 610 is fixed within the first indoor air outlet passage 320 and the first outdoor air outlet passage 330. At this time, the first heat exchanger 610 can be an integral unit or can be composed of two connected parts; the second heat exchanger 620 is fixed within the second indoor air outlet passage 520 and the second outdoor air outlet passage. At this time, the second heat exchanger 620 can be an integral unit or can be composed of two connected parts.

[0033] The first heat exchanger 610 is arranged as an evaporator, and the second heat exchanger 620 is arranged as a condenser.

[0034] For this air conditioner 900, by reasonably controlling the opening and closing states of the heat exchange system, the first fan assembly 200, and the second fan assembly 400, and reasonably controlling the on-off states of the first indoor air outlet passage 320, the first outdoor air outlet passage 330, the second indoor air outlet passage 520, and the second outdoor air outlet passage 530, the functions of heating, cooling, dehumidifying, and exhausting can be respectively achieved, and it can be better applied to application scenarios such as bathrooms.

[0035] As Figure 1 , Figure 5 and Figure 8 shown, the heat exchange system includes components such as a compressor 630, a first heat exchanger 610, and a second heat exchanger 620, without a reversing valve (i.e., a four-way reversing valve).

[0036] The first heat exchanger 610 is arranged as an evaporator, and the second heat exchanger 620 is arranged as a condenser.

[0037] This air conditioner 900 is applied to a bathroom, and both the first air inlet 110 and the second air inlet 120 communicate with the interior of the room (inside the bathroom).

[0038] Dehumidifying mode: As Figures 8 to 10 shown, start (i.e., turn on) the compressor 630, the first fan assembly 200, and the second fan assembly 400, conduct the first indoor air outlet passage 320 and the second indoor air outlet passage 520, and cut off the first outdoor air outlet passage 330 and the second outdoor air outlet passage 530. In this way, the air in the bathroom enters the first air inlet passage 310 from the first air inlet 110, is cooled and condensed by the evaporator, and then is blown into the bathroom through the first indoor air outlet passage 320. The formed condensed water can be discharged outside the bathroom through the water receiving tray and the water guide pipe, realizing dehumidification of the bathroom; during this process, the air in the bathroom also enters the second air inlet passage 510 from the second air inlet 120, is heated by the condenser, and takes away the heat on the condenser to ensure the continuous operation of the heat exchange system.

[0039] Exhaust mode (not shown in the figure): Turn off the compressor 630, start (i.e., turn on) the first blower assembly 200 and the second blower assembly 400, shut off the first indoor air outlet passage 320 and the second indoor air outlet passage 520, and conduct the first outdoor air outlet passage 330 and the second outdoor air outlet passage 530. In this way, the air in the bathroom enters the first air inlet passage 310 and the second air inlet passage 510 from the first air inlet 110 and the second air inlet 120 respectively, and is discharged to the outside of the bathroom along the first outdoor air outlet passage 330 and the second outdoor air outlet passage 530 respectively, realizing the exhaust of the bathroom.

[0040] Cooling mode: As Figures 1 to 4 shown, start (i.e., turn on) the compressor 630, the first blower assembly 200 and the second blower assembly 400, conduct the first indoor air outlet passage 320 and the second outdoor air outlet passage 530, and shut off the first outdoor air outlet passage 330 and the second indoor air outlet passage 520. In this way, the air in the bathroom enters the first air inlet passage 310 from the first air inlet 110, is cooled by the evaporator, and then is blown into the bathroom through the first indoor air outlet passage 320. During this process, the air in the bathroom also enters the second air inlet passage 510 from the second air inlet 120, is heated by the condenser to take away the heat on the condenser, and then is blown to the outside of the bathroom through the second outdoor air outlet passage 530, realizing the cooling of the bathroom and solving the problem of sultriness in the bathroom in summer.

[0041] Heating mode: As Figures 5 to 7 shown, start (i.e., turn on) the compressor 630, the first blower assembly 200 and the second blower assembly 400, shut off the first indoor air outlet passage 320 and the second outdoor air outlet passage 530, and conduct the first outdoor air outlet passage 330 and the second indoor air outlet passage 520. In this way, the air in the bathroom enters the second air inlet passage 510 from the second air inlet 120, is heated by the condenser, and then is blown into the bathroom through the second indoor air outlet passage 520. During this process, the air in the bathroom also enters the first air inlet passage 310 from the first air inlet 110, is cooled by the evaporator, and then is blown to the outside of the bathroom through the first outdoor air outlet passage 330, realizing the heating of the bathroom.

[0042] Of course, it can also be that an installation cover 190 is further fixed on the housing 100, a mixed air outlet 191 is provided on the installation cover 190, and the open end of the installation cover 190 covers the first indoor air outlet 131 and the second indoor air outlet 132, so that both the first indoor air outlet 131 and the second indoor air outlet 132 are communicated with the mixed air outlet 191. When dehumidifying, the cold air and the hot air converge at the mixed air outlet 191 and are blown into the bathroom, which can achieve the effect of constant temperature dehumidification and can also achieve the purpose of this application. Its gist does not deviate from the design idea of the present invention, so it will not be elaborated here and should also fall within the protection scope of this application.

[0043] In an exemplary embodiment, as Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figures 9 to 12 shown, the air conditioner 900 is further provided with a first door 710, the first door 710 is movably installed, and the first door 710 selectively shuts off (i.e., selectively conducts) the first indoor air outlet passage 320 and the first outdoor air outlet passage 330; in addition, the air conditioner 900 is further provided with a second door, the second door is movably installed, and the second door selectively shuts off (i.e., selectively conducts) the second indoor air outlet passage 520 and the second outdoor air outlet passage 530.

[0044] It may be that, as Figure 11 and Figure 12 shown, the first fan assembly 200 is provided to include a first impeller 240 and a first volute 250, the first impeller 240 is rotatably installed in the first volute 250, the first fan air inlet 210 is provided on the side wall of the first volute 250, and the first fan sub-air outlet 220 and the second fan sub-air outlet 230 are provided on the peripheral wall of the first volute 250.

[0045] As Figure 2 , Figure 6 , Figure 9 , Figure 11 and Figure 12 shown, there is a first indoor air outlet passage 320 between the first fan sub-air outlet 220 and the first indoor air outlet 131, and the first indoor air outlet passage 320 can be conducted and shut off. There is a first outdoor air outlet passage 330 between the second fan sub-air outlet 230 and the first outdoor air outlet 141, and the first outdoor air outlet passage 330 can be conducted and shut off. The first fan sub-air outlet 220 and the second fan sub-air outlet 230 are provided on the peripheral wall of the first volute 250 with an interval of 180 degrees. The air conditioner 900 is further provided with a first driving mechanism 720, the first door 710 is fixed on the first driving mechanism 720, and the first driving mechanism 720 drives the first door 710 to rotate along the peripheral wall of the first volute 250, so as to selectively shut off the first fan sub-air outlet 220 and the second fan sub-air outlet 230, so as to realize that the first door 710 selectively conducts (i.e., selectively shuts off) the first indoor air outlet passage 320 and the first outdoor air outlet passage 330. By driving the first door 710 to act through the first driving mechanism 720, compared with manually driving the first door 710 to act, the degree of automation is higher.

[0046] Among them, as Figure 11 and Figure 12As shown, the first driving mechanism 720 is configured to include a driving motor 721 and a transmission gear set 722 mounted on the driving motor 721. The transmission gear set 722 is configured to include a first gear mounted on the driving motor 721 and a second gear meshing with the first gear. The first door body 710 is configured to include two arc-shaped door bodies. The air outlet 220 of the first blower and the air outlet 230 of the second blower protrude outward from the peripheral wall of the first volute 250. The two arc-shaped door bodies are located outside the first volute 250, and sockets 260 are provided on the wall of the air outlet 220 of the first blower and the wall of the air outlet 230 of the second blower. The two arc-shaped door bodies are configured to be mounted on the second gear and rotate with the second gear, and are respectively used to extend into the sockets 260 to block the air outlet 220 of the first blower and the air outlet 230 of the second blower; that is, when an arc-shaped door body is inserted into a socket to block the air outlet 220 of the first blower, the other arc-shaped door body is located outside the other socket and keeps the air outlet 230 of the second blower open; when the other arc-shaped door body is inserted into the other socket to block the air outlet 230 of the second blower, an arc-shaped door body is located outside a socket and keeps the air outlet 220 of the first blower open. Of course, the first door body 710 can also be configured as an arc-shaped door body. By mounting an arc-shaped door body on the second gear to respectively block the air outlet 220 of the first blower and the air outlet 230 of the second blower, the purpose of the present application can also be achieved. Its gist does not deviate from the design concept of the present invention, and will not be elaborated here, and should also fall within the protection scope of the present application.

[0047] It may be, such as Figure 3 , Figure 4 , Figure 7 and Figure 10As shown, the second fan assembly 400 is configured to include a second impeller 440 and a second volute 450. The second impeller 440 is arranged to be installed inside the second volute 450. The second fan air inlet 410 is arranged on the side wall of the second volute 450. The third fan sub-air outlet 420 and the fourth fan sub-air outlet 430 are arranged on the peripheral wall of the second volute 450. The third fan sub-air outlet 420 and the fourth fan sub-air outlet 430 are arranged at an interval of 180 degrees on the peripheral wall of the second volute 450. There is a second indoor air outlet passage 520 between the third fan sub-air outlet 420 and the second indoor air outlet 132, and the second indoor air outlet passage 520 can be conducted and shut off. There is a second outdoor air outlet passage 530 between the fourth fan sub-air outlet 430 and the second outdoor air outlet 142, and the second outdoor air outlet passage 530 can be conducted and shut off. The air conditioner 900 is further configured to include a second driving mechanism. The second door body is fixed on the second driving mechanism. The second driving mechanism is used to drive the second door body to rotate along the peripheral wall of the second volute 450, and selectively block the third fan sub-air outlet 420 and the fourth fan sub-air outlet 430, so as to realize that the second door body selectively conducts (i.e., selectively shuts off) the second indoor air outlet passage 520 and the second outdoor air outlet passage 530. By driving the second door body to act through the second driving mechanism, compared with manually driving the second door body to act, the degree of automation is higher.

[0048] Among them, the structure of the second driving mechanism and the first driving mechanism 720 is set to be the same, and the structure of the second door body and the first door body 710 is also set to be the same (see Figure 11 and Figure 12 ), so as to realize the common use of the first fan assembly 200 and the second fan assembly 400.

[0049] In an exemplary embodiment, the air conditioner 900 further includes: a heating device, which is arranged in the second air inlet passage or the second indoor air outlet passage (not shown in this schematic diagram).

[0050] The heating device can be set as a PCT heater or a heating wire, etc., all of which can achieve the purpose of the present application. Its gist does not deviate from the design concept of the present invention, and will not be elaborated here, and all should fall within the protection scope of the present application.

[0051] The heating device can be started simultaneously in the aforementioned heating mode. Or, only the heating device is used for heating, and the compressor 630 and the first fan assembly 200 are turned off. At this time, the heating mode is:

[0052] Start (i.e., turn on) the second blower assembly 200 and the heating device, turn off the second outdoor air outlet passage 530, and turn on the second indoor air outlet passage 520. In this way, the air in the bathroom enters the second air inlet passage 510 from the second air inlet 120, is heated by the heating device, and then blown into the bathroom through the second indoor air outlet passage 520 to achieve heating of the bathroom. The heating efficiency can be changed by changing the number of heating devices turned on.

[0053] Of course, it can also be that, as Figure 1 , Figure 5 and Figure 8 shown, the heating device 800 is arranged in the first air inlet passage 310 or the first indoor air outlet passage 320. In the heating mode, the compressor 630 is turned off, and only the heating device 800 is relied on for heating. That is, in the heating mode: start (i.e., turn on) the first blower assembly 200 and the heating device, turn off the compressor 630 and the second blower assembly 400, turn off the first outdoor air outlet passage 330, and turn on the first indoor air outlet passage 320. The air in the bathroom enters the first air inlet passage 310 from the first air inlet 110, is heated by the heating device, and then blown into the bathroom through the first indoor air outlet passage 320 to achieve heating of the bathroom. The heating efficiency can be changed by changing the number of heating devices 800 turned on. The above solution can also achieve the purpose of this application, and its gist does not deviate from the design concept of the present invention, so it will not be elaborated here and should also fall within the protection scope of this application.

[0054] Of course, a four-way reversing valve can also be added to the heat exchange system, and the bathroom interior can be heated by jointly heating through the evaporator and the heating device, which can also achieve the purpose of this application. Its gist does not deviate from the design concept of the present invention, so it will not be elaborated here and should also fall within the protection scope of this application.

[0055] The air conditioner 900 provided in the above embodiment can respectively achieve the functions of heating, cooling, dehumidifying, and exhausting, and can be better applicable to application scenarios such as bathrooms.

[0056] Embodiment 2

[0057] The difference between this embodiment and the first embodiment is that on the first indoor air outlet channel, a first switching valve is installed, which conducts and shuts off the first indoor air outlet channel; on the first outdoor air outlet channel, a second switching valve is installed, which conducts and shuts off the first outdoor air outlet channel; on the second indoor air outlet channel, a third switching valve is installed, which conducts and shuts off the second indoor air outlet channel; on the second outdoor air outlet channel, a fourth switching valve is installed, which conducts and shuts off the second outdoor air outlet channel (not shown in the figure of this solution). The first switching valve, the second switching valve, the third switching valve, and the fourth switching valve are all set as solenoid valves. To ensure the air volume, the inner diameter of the solenoid valve needs to be relatively large, so the volume of this kind of solenoid valve is relatively large. Although this structural design is simpler, the cost of the air conditioner 900 will increase significantly, and the size will also increase significantly.

[0058] Of course, the first switching valve, the second switching valve, the third switching valve, and the fourth switching valve can also be all set as other electronically controlled flow valves, which can also achieve the object of the present application. Without departing from the design concept of the present invention, it will not be elaborated here and should also fall within the protection scope of the present application.

[0059] Embodiment Three

[0060] The difference between this embodiment and the first embodiment is that the air conditioner 900 further includes: a first indoor air inlet sub-channel, which can be conducted and shut off.
