Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] Fresh air conditioners are widely used in daily life as a type of household appliance. They can both regulate indoor air temperature and replace indoor air.

[0003] In related technologies, a fresh air air conditioner mainly includes a casing, a first heat exchanger, a second heat exchanger, a first fan, and a second fan. A fresh air duct and a return air duct are formed inside the casing. The first heat exchanger and the first fan are located within the fresh air duct, while the second heat exchanger and the second fan are located within the return air duct. The first and second heat exchangers are used to regulate the indoor air temperature.

[0004] However, during refrigeration, because the temperature of the first and second heat exchangers is low, the cold energy on them will radiate to the surroundings. This will cause the temperature of the casing near the first and second heat exchangers to be low. As a result, when the warmer air outside the casing comes into contact with the casing, condensation will form on the outer surface of the casing. Summary of the Invention

[0005] This application provides an air conditioner to solve the problem of condensation occurring on the casing near the first and second heat exchangers due to low temperatures.

[0006] This application provides an air conditioner, including a casing, a first heat exchanger, a second heat exchanger, a first partition, a second partition, a first adjusting member, and a second adjusting member. A return air duct and a fresh air duct are formed inside the casing. The first heat exchanger is disposed within the return air duct; the second heat exchanger is disposed within the fresh air duct; the first partition is disposed within the return air duct and forms a first bypass branch with the duct wall of the return air duct. The vertical projection of the first heat exchanger on the first partition at least partially coincides with the first partition. The first air inlet of the first bypass branch is connected to a portion of the air inlet side of the first heat exchanger in the return air duct, and the first air outlet of the first bypass branch is connected to the return air duct. The first heat exchanger of the duct is connected to the air outlet side; the second baffle is set in the fresh air duct and forms a second bypass branch with the duct wall of the fresh air duct. The vertical projection of the second heat exchanger on the second baffle is at least partially overlapping with the second baffle. The second air inlet of the second bypass branch is connected to the air inlet side of the second heat exchanger of the fresh air duct. The second air outlet of the second bypass branch is connected to the air outlet side of the second heat exchanger of the fresh air duct. The first adjusting member is set on the first bypass branch for opening or closing the first bypass branch. The second adjusting member is set on the second bypass branch for opening or closing the second bypass branch.

[0007] In the normal mode, the air conditioner of this application allows indoor air to enter the return air duct, undergo heat exchange in the first heat exchanger, and then re-enter the room, thus regulating the indoor temperature. In the fresh air mode, outdoor air enters the fresh air duct, undergoes heat exchange in the second heat exchanger, and then enters the room, thus replacing the indoor air.

[0008] Since the vertical projection of the first heat exchanger on the first partition plate is at least partially aligned with the first partition plate, during cooling, when the cold energy on the first heat exchanger radiates to the surroundings, at least a portion of it will radiate onto the first partition plate, and then further radiate onto the casing through the first partition plate. At this time, the first adjusting element can be adjusted to open the first bypass branch. Since the first air inlet of the first bypass branch is partially connected to the air inlet side of the first heat exchanger in the return air duct, and the air in the return air duct on this side is hot air because it has not passed through the first heat exchanger, the hot air will enter the first bypass branch. This can heat the first partition plate and also form a heat insulation space between the first partition plate and the casing, which can prevent the cold energy on the first partition plate from radiating onto the casing, prevent the temperature of the casing near the first partition plate from dropping, and thus prevent condensation from appearing on the outer wall of the casing.

[0009] Similarly, since the vertical projection of the second heat exchanger on the second partition plate is at least partially aligned with the second partition plate, during cooling, when the cold energy on the second heat exchanger radiates to the surroundings, at least a portion of it will radiate onto the second partition plate, and then further radiate onto the casing through the second partition plate. At this time, the second adjustment element can be adjusted to open the second bypass branch. Since the second air inlet of the second bypass branch is partially connected to the air inlet side of the second heat exchanger in the fresh air duct, and the air in the fresh air duct on this side is hot air because it has not passed through the second heat exchanger, the hot air will enter the second bypass branch. This can heat the second partition plate and also form a heat insulation space between the second partition plate and the casing, which can prevent the cold energy on the second partition plate from radiating onto the casing, prevent the temperature of the casing near the second partition plate from dropping, and thus prevent condensation from appearing on the outer wall of the casing.

[0010] By cooperating with the first bypass branch and the first regulating component, the temperature on the casing near the first heat exchanger is prevented from being too low, thus avoiding condensation. By cooperating with the second bypass branch and the second regulating component, the temperature on the casing near the second heat exchanger is prevented from being too low, thus avoiding condensation.

[0011] In some embodiments of this application, the vertical projection of the first heat exchanger onto the first partition plate is within the range of the first partition plate.

[0012] By implementing the above configuration, more of the cooling energy from the first heat exchanger is radiated onto the first baffle, thus reducing the probability of the cooling energy from the first heat exchanger radiating to other parts of the air conditioner. This better solves the condensation problem caused by the cooling energy from the first heat exchanger.

[0013] In some embodiments of this application, the vertical projection of the second heat exchanger onto the second partition plate is within the range of the second partition plate.

[0014] By implementing the above configuration, more of the cooling energy from the second heat exchanger is radiated onto the second baffle, thus reducing the probability of the cooling energy from the second heat exchanger radiating to other parts of the air conditioner. This better solves the condensation problem caused by the cooling energy from the second heat exchanger.

[0015] In some embodiments of this application, both the first air inlet and the first air outlet are located on the first partition; the first adjusting member includes a first air valve and a second air valve, the first air valve being fixed at the first air inlet for opening or closing the first air inlet; and the second air valve being fixed at the first air outlet for opening or closing the first air outlet.

[0016] The first air inlet is opened or closed by using the first air valve, and the first air outlet is opened or closed by using the second air valve. The first and second air valves can dually regulate the on / off state of the first bypass branch, making it safer and more efficient.

[0017] In some embodiments of this application, both the second air inlet and the second air outlet are located on the second partition; the second adjusting member includes a third air valve and a fourth air valve, the third air valve being fixed at the second air inlet for opening or closing the second air inlet; and the fourth air valve being fixed at the second air outlet for opening or closing the second air outlet.

[0018] The second air inlet is opened or closed using the third air valve, and the second air outlet is opened or closed using the fourth air valve. The third and fourth air valves can dually regulate the on / off state of the second bypass branch, making it safer and more efficient.

[0019] In some embodiments of this application, the air conditioner further includes a first temperature sensor disposed in the first bypass branch and fixed to the first partition. The first temperature sensor is used to detect a first actual temperature value on the first partition. The first temperature sensor is electrically connected to the first regulating member. When the first actual temperature value is lower than the first preset temperature value, the first regulating member opens the first bypass branch. When the first actual temperature value is higher than the first preset temperature value, the first regulating member closes the first bypass branch.

[0020] A first temperature sensor is used to detect the temperature on the first partition, so as to control the first regulating element to open or close the first bypass branch at the appropriate time. In this way, when it is necessary to open the first bypass branch, it can be opened to increase the temperature on the first partition; when it is not necessary to open the first bypass branch, it can be closed, so that a portion of the air on the inlet side of the first heat exchanger in the return air duct is heat-exchanged by the first heat exchanger before entering the room, thereby improving energy efficiency.

[0021] In some embodiments of this application, the air conditioner further includes a second temperature sensor disposed in the second bypass branch and fixed to the second partition. The second temperature sensor is used to detect a second actual temperature value on the second partition. The second temperature sensor is electrically connected to the second regulating member. When the second actual temperature value is lower than the second preset temperature value, the second regulating member opens the second bypass branch. When the second actual temperature value is higher than the second preset temperature value, the second regulating member closes the second bypass branch.

[0022] A second temperature sensor is used to detect the temperature on the second partition, allowing the second regulating element to open or close the second bypass branch at appropriate times. Thus, when the second bypass branch needs to be opened, it can be opened to regulate the temperature on the second partition; when it does not need to be opened, it can be closed, ensuring that a portion of the air entering the room from the inlet side of the second heat exchanger in the fresh air duct is heated by the second heat exchanger, thereby improving energy efficiency.

[0023] In some embodiments of this application, the air conditioner further includes a first humidity sensor fixed to the outer wall of the casing, used to detect the first actual humidity value of condensation generated by the cooling energy radiated from the first partition on the casing to the casing. The first humidity sensor is electrically connected to the first regulating member. When the first actual humidity value is lower than the first preset humidity value, the first regulating member opens the first bypass branch. When the first actual humidity value is higher than the first preset humidity value, the first regulating member closes the first bypass branch.

[0024] With the above settings, when the humidity on the casing near the first partition is too high, the first bypass branch is opened to heat the first partition and the casing, thereby preventing the continued generation of condensation.

[0025] In some embodiments of this application, the air conditioner further includes a second humidity sensor fixed to the outer wall of the casing, used to detect the second actual humidity value of condensation generated by the cooling energy radiated from the second partition on the casing to the casing. The second humidity sensor is electrically connected to the second regulating member. When the second actual humidity value is lower than the second preset humidity value, the second regulating member opens the second bypass branch. When the second actual humidity value is higher than the second preset humidity value, the second regulating member closes the second bypass branch.

[0026] With the above settings, when the humidity on the casing near the second partition is too high, the second bypass branch is opened to heat the second partition and the casing, thereby preventing the continued generation of condensation.

[0027] In some embodiments of this application, the housing has an inner cavity; the air conditioner also includes a baffle that divides the inner cavity into a return air duct and a fresh air duct, a first bypass branch is formed between the first baffle and the inner wall of the inner cavity, and a second bypass branch is formed between the second baffle and the inner wall of the inner cavity.

[0028] The inner cavity is divided into a return air duct and a fresh air duct by a baffle, which facilitates the formation of the return air duct and the fresh air duct. In this case, a first bypass branch is formed between the first baffle and the inner wall of the inner cavity to ensure that the first bypass branch can heat the first baffle; a second bypass branch is formed between the second baffle and the inner wall of the inner cavity to ensure that the second bypass branch can heat the second baffle.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] In summer and winter, indoor temperatures often become too high or too low. If the indoor temperature is not adjusted in time, it is difficult for people to work or live comfortably in such an environment.

[0047] Based on this, such as Figure 1 As shown, this application provides an air conditioner 10, including a housing 100, a first heat exchanger 200 and a first fan 210. A return air duct 110 is formed inside the housing 100, and both ends of the return air duct 110 are connected to the indoor environment. The first heat exchanger 200 and the first fan 210 are both disposed inside the return air duct 110.

[0048] When indoor temperature needs to be adjusted, the first fan 210 is activated. Under the action of the first fan 210, indoor air is drawn into the return air duct 110. Within the return air duct 110, the air passes through the first heat exchanger 200, where energy exchange occurs, resulting in cooler or warmer air, which is then exhausted back into the room. By installing the first heat exchanger 200 within the return air duct 110, the indoor air temperature is regulated, ensuring a more comfortable environment for occupants.

[0049] For example, in summer, when the initial indoor air temperature is relatively high, the first fan 210 is started to draw the high-temperature indoor air into the return air duct 110. At the first heat exchanger 200, the first heat exchanger 200 absorbs the heat from the high-temperature air, turning the high-temperature air into low-temperature air. Then, under the action of the first fan 210, the low-temperature air is discharged into the room, thereby lowering the indoor temperature and making the room cool.

[0050] For example, in winter, the initial indoor air temperature is relatively low. At this time, the first fan 210 is started to draw the low-temperature indoor air into the return air duct 110. At the first heat exchanger 200, the first heat exchanger 200 releases heat into the low-temperature air, turning the low-temperature air into high-temperature air. Then, under the action of the first fan 210, the high-temperature air is discharged into the room, thereby raising the indoor temperature and making the room warm.

[0051] To prevent outdoor air from entering the room or indoor air from escaping to the outside and affecting the indoor temperature, doors and windows are usually kept closed when cooling or heating to ensure that the indoor temperature remains within a suitable range for a long time.

[0052] However, due to the activities of people indoors, the carbon dioxide content in the indoor air will increase over time, and the indoor air will become polluted. In order to improve the quality of indoor air as much as possible while ensuring the indoor air temperature, we need to address this issue.

[0053] like Figure 1 As shown, a fresh air duct 120 is also formed inside the casing 100. One end of the fresh air duct 120 is connected to the indoor unit, and the other end of the fresh air duct 120 is connected to the outdoor unit. The air conditioner 10 also includes a second heat exchanger 220 and a second fan 230, which are disposed inside the fresh air duct 120.

[0054] When it is necessary to improve indoor air quality, the second fan 230 is activated to introduce fresh outdoor air into the room, providing fresh air for the indoor environment. Since a second heat exchanger 220 is installed in the fresh air duct 120, when the air passes through the second heat exchanger 220, energy exchange occurs there, transforming the air into air that meets the indoor temperature requirements. This ensures that the temperature of the air entering the room through the fresh air duct 120 is not significantly different from the original indoor air temperature, thus guaranteeing that the introduction of fresh air will not affect the temperature of the existing indoor air.

[0055] When the first heat exchanger 200 and the second heat exchanger 220 are operating, water droplets will be generated. To prevent these water droplets from falling into the return air duct 110 and the fresh air duct 120, such as... Figure 1 As shown, the air conditioner 10 also includes a water collection tray 300, which is located below the first heat exchanger 200 and the second heat exchanger 220. The water collection tray 300 collects water droplets dripping from the first heat exchanger 200 and the second heat exchanger 220, preventing water from dripping directly into the return air duct 110 and the fresh air duct 120, thereby preventing water from accumulating and seeping out to the outside of the casing 100.

[0056] In this case, in order to ensure the stability of the water receiving tray 300, the first heat exchanger 200 and the second heat exchanger 220, the first heat exchanger 200 can be fixed to the water receiving tray 300 and the second heat exchanger 220 can be fixed to the water receiving tray 300. In this case, the water receiving tray 300 can be used to form part of the duct wall of the fresh air duct 120 and the return air duct 110, so as to facilitate the fixing of the first heat exchanger 200 to the water receiving tray 300 and the second heat exchanger 220 to the water receiving tray 300.

[0057] In some embodiments, in order to form a return air duct 110 and a fresh air duct 120 within the housing 100, such as Figure 1 As shown, the housing 100 has an inner cavity 130 inside. The air conditioner 10 also includes a baffle 140, which divides the inner cavity 130 into a return air duct 110 and a fresh air duct 120. That is, a return air duct 110 is formed between one side of the baffle 140 and the inner wall of the inner cavity 130 (the inner wall of the housing 100), and a fresh air duct 120 is formed between the other side of the baffle 140 and the inner wall of the inner cavity 130.

[0058] A baffle 140 directly divides the inner cavity 130 into a return air duct 110 and a fresh air duct 120, saving the material used to form the return air duct 110 and the fresh air duct 120. Moreover, when forming the return air duct 110 and the fresh air duct 120, the inner cavity 130 only needs to be divided once, which is more convenient.

[0059] The baffle 140 and the housing 100 can be integrally formed, which increases the overall structural strength. In the actual manufacturing process, the positions and shapes of the return air duct 110 and the fresh air duct 120 are first planned, and then cutting and other techniques are used to manufacture the baffle 140, the fresh air duct 120, and the return air duct 110.

[0060] Alternatively, the baffle 140 can be a separate structure from the housing 100. The baffle 140 and the housing 100 can be manufactured separately, and then the baffle 140 can be fixed inside the housing 100 using screws or other methods. Designing the baffle 140 and the housing 100 as separate structures simplifies the manufacturing process, as both can be manufactured separately.

[0061] Or, such as Figure 2As shown, the air conditioner 10 may also include two baffles 140, one of which forms a return air duct 110 with the inner wall of the cavity 130, and the other baffle forms a fresh air duct with the inner wall of the cavity 130. The two baffles 140 form the return air duct 110 and the fresh air duct 120 with the inner wall of the cavity 130, respectively. The arrangement of the fresh air duct 120 and the return air duct 110 does not affect each other and can be rationally arranged according to the space of the cavity 130.

[0062] Based on this, when cooling the room, the temperature of the first heat exchanger 200 and the second heat exchanger 220 is low, so the cold energy on them will radiate to the surroundings. This will cause the temperature of the casing 100 near the first heat exchanger 200 and the second heat exchanger 220 to be low. As a result, when the warmer air outside the casing 100 comes into contact with the casing 100, condensation will form on the outer surface of the casing 100.

[0063] Based on this, such as Figure 3 As shown, the air conditioner 10 provided in this application also includes a first partition 400, a second partition 410, a first adjusting member 500, and a second adjusting member 600.

[0064] The first partition 400 is disposed in the return air duct 110 and forms a first bypass branch 150 with the duct wall of the return air duct 110. The vertical projection of the first heat exchanger 200 on the first partition 400 is at least partially coincident with the first partition 400. The first air inlet of the first bypass branch 150 is connected to a portion of the air inlet side of the first heat exchanger 200 in the return air duct 110. The first air outlet of the first bypass branch 150 is connected to a portion of the air outlet side of the first heat exchanger 200 in the return air duct 110.

[0065] The second partition 410 is disposed inside the fresh air duct 120 and forms a second bypass branch 160 with the duct wall of the fresh air duct 120. The vertical projection of the second heat exchanger 220 on the second partition 410 is at least partially coincident with the second partition 410. The second air inlet of the second bypass branch 160 is connected to a portion of the air inlet side of the second heat exchanger 220 in the fresh air duct 120. The second air outlet of the second bypass branch 160 is connected to a portion of the air outlet side of the second heat exchanger 220 in the fresh air duct 120.

[0066] The first adjusting member 500 is disposed on the first bypass branch 150 and is used to open or close the first bypass branch 150; the second adjusting member 600 is disposed on the second bypass branch 160 and is used to open or close the second bypass branch 160.

[0067] With the above arrangement, since the vertical projection of the first heat exchanger 200 onto the first partition 400 at least partially coincides with the first partition 400, during cooling, when the cold energy on the first heat exchanger 200 radiates to the surroundings, at least a portion of it will radiate onto the first partition 400, and then further radiate onto the casing 100 through the first partition 400. Figure 4 As shown, the first adjusting component 500 can be adjusted at this time to open the first bypass branch 150. Since the first air inlet of the first bypass branch 150 is connected to the air inlet side of the first heat exchanger 200 of the return air duct 110, and the air in the return air duct 110 on this side is hot air because it has not passed through the first heat exchanger 200, the hot air will enter the first bypass branch 150. This can heat the first partition 400 and form a heat insulation space between the first partition 400 and the casing 100. This can prevent the cold air on the first partition 400 from radiating to the casing 100 and prevent the temperature of the casing 100 near the first partition 400 from dropping, thereby preventing condensation from appearing on the outer wall of the casing 100.

[0068] Similarly, since the vertical projection of the second heat exchanger 220 onto the second partition 410 at least partially coincides with the second partition 410, during cooling, when the cold energy on the second heat exchanger 220 radiates to the surroundings, at least a portion of it will radiate onto the second partition 410, and then further radiate onto the casing 100 through the second partition 410. Figure 4 As shown, the second adjusting element 600 can be adjusted at this time to open the second bypass branch 160. Since the second air inlet of the second bypass branch 160 is connected to the air inlet side of the second heat exchanger 220 of the fresh air duct 120, and the air in the fresh air duct 120 on this side is hot air because it has not passed through the second heat exchanger 220, the hot air will enter the second bypass branch 160. This can heat the second partition 410 and form a heat insulation space between the second partition 410 and the casing 100, which can prevent the cold air on the second partition 410 from radiating to the casing 100 and prevent the temperature of the casing 100 near the second partition 410 from dropping, thereby preventing condensation from appearing on the outer wall of the casing 100.

[0069] By cooperating with the first bypass branch 150 and the first regulating component 500, the temperature on the casing 100 near the first heat exchanger 200 is prevented from being too low, thus avoiding condensation. By cooperating with the second bypass branch 160 and the second regulating component 600, the temperature on the casing 100 near the second heat exchanger 220 is prevented from being too low, thus avoiding condensation.

[0070] In this case, when the return air duct 110 and the fresh air duct 120 are formed by a baffle 140 separating the inner cavity 130, in order to form the first bypass branch 150 and the second bypass branch 160, the first bypass branch 150 is formed between the first baffle 400 and the inner wall of the inner cavity 130, and the second bypass branch 160 is formed between the second baffle 410 and the inner wall of the inner cavity 130.

[0071] Since the baffle 140 serves as both the duct wall of the return air duct 110 and the duct wall of the fresh air duct 120, it is located between the return air duct 110 and the fresh air duct 120. Therefore, even if the cooling energy on the first heat exchanger 200 and the second heat exchanger 220 radiates to the baffle 140 at the same time, it is difficult to directly conduct it to the casing 100. In this case, it is only necessary to form a first bypass branch 150 between the first partition 400 and the inner wall of the inner cavity 130, and a second bypass branch 160 between the second partition 410 and the inner wall of the inner cavity 130, so as to prevent the cooling energy on the first partition 400 and the second partition 410 from being conducted to other sides.

[0072] Alternatively, the first partition 400 can be arranged around the extension direction of the return air duct 110, so that an annular first bypass branch 150 is formed between the first partition 400 and the inner wall of the inner cavity 130, which can prevent the cold energy on the first heat exchanger 200 from radiating to the casing 100 along the extension direction perpendicular to the return air duct 110.

[0073] Similarly, the second partition 410 can also be arranged around the extension direction of the fresh air duct 120, so that an annular second bypass branch 160 is formed between the second partition 410 and the inner wall of the inner cavity 130, which can prevent the cold energy on the second heat exchanger 220 from radiating to the casing 100 along the extension direction perpendicular to the fresh air duct 120.

[0074] Based on this, such as Figure 5 As shown, both the first air inlet and the first air outlet are located on the first partition 400; the first adjusting member 500 includes a first air valve 510 and a second air valve 520. The first air valve 510 is fixed at the first air inlet and is used to open or close the first air inlet; the second air valve 520 is fixed at the first air outlet and is used to open or close the first air outlet.

[0075] In this way, the first air inlet can be opened or closed using the first air valve 510, and the first air outlet can be opened or closed using the second air valve 520. The first air valve 510 and the second air valve 520 can dually regulate the on / off state of the first bypass branch 150, making it safer and more efficient.

[0076] The first air valve 510 and the second air valve 520 can be the same type of air valve, or they can be different types of air valves. This application does not make any specific limitations in this regard.

[0077] Alternatively, the first regulating element 500 may simply include a fifth air valve, which is installed on the first bypass branch 150. This fifth air valve allows for the opening or closing of the first bypass branch 150. This achieves control over the on / off state of the first bypass branch 150 while saving materials and reducing costs.

[0078] Alternatively, the first adjusting member 500 may further include a first adjusting plate and a first motor, with the first motor fixed inside the first bypass branch 150 and the first adjusting plate disposed inside the first bypass branch 150. The first adjusting plate is movably connected to the inner wall of the first bypass branch 150, and the first adjusting plate can move between a first position and a second position. In the first position, the first adjusting plate opens the first bypass branch 150; in the second position, the first adjusting plate closes the first bypass branch 150. The first motor is used to drive the first adjusting plate to move between the first position and the second position.

[0079] With the above settings, the first motor and the first adjusting plate are used in conjunction to drive the first adjusting plate to move between the first position and the second position, so as to open or close the first bypass branch 150.

[0080] Similarly, such as Figure 6 As shown, both the second air inlet and the second air outlet are located on the second partition 410; the second adjusting member 600 includes a third air valve 610 and a fourth air valve 620. The third air valve 610 is fixed at the second air inlet and is used to open or close the second air inlet; the fourth air valve 620 is fixed at the second air outlet and is used to open or close the second air outlet.

[0081] In this way, the second air inlet can be opened or closed using the third air valve 610, and the second air outlet can be opened or closed using the fourth air valve 620. The third air valve 610 and the fourth air valve 620 can dually regulate the on / off state of the second bypass branch 160, making it safer and more efficient.

[0082] The third air valve 610 and the fourth air valve 620 can be the same type of air valve, or they can be different types of air valves. This application does not make specific limitations in this regard.

[0083] Alternatively, the second regulating element 600 may simply include a sixth air valve, which is installed on the second bypass branch 160. This sixth air valve allows for the opening or closing of the second bypass branch 160. This achieves control over the on / off state of the second bypass branch 160 while saving materials and reducing costs.

[0084] Alternatively, the second adjusting member 600 may further include a second adjusting plate and a second motor, with the second motor fixed inside the second bypass branch 160 and the second adjusting plate disposed inside the second bypass branch 160. The second adjusting plate is movably connected to the inner wall of the second bypass branch 160, and the second adjusting plate can move between a third position and a fourth position. In the third position, the second adjusting plate opens the second bypass branch 160; in the fourth position, the second adjusting plate closes the second bypass branch 160. The second motor is used to drive the second adjusting plate to move between the third and fourth positions.

[0085] With the above configuration, the second motor and the second adjusting plate are used in conjunction to drive the second adjusting plate to move between the third and fourth positions, so as to open or close the second bypass branch 160.

[0086] To facilitate control of the first adjusting element 500, such as Figure 7 As shown, the air conditioner 10 also includes a first temperature sensor 700, which is disposed in the first bypass branch 150 and fixed on the first partition 400. The first temperature sensor 700 is used to detect the first actual temperature value on the first partition 400. The first temperature sensor 700 is electrically connected to the first regulating member 500.

[0087] When the first actual temperature value is lower than the first preset temperature value, the first adjusting member 500 opens the first bypass branch 150; when the first actual temperature value is higher than the first preset temperature value, the first adjusting member 500 closes the first bypass branch 150.

[0088] With the above configuration, the temperature on the first partition 400 is detected by the first temperature sensor 700, so as to control the first regulating element 500 to open or close the first bypass branch 150 at the appropriate time. Thus, when it is necessary to open the first bypass branch 150, it can be opened to increase the temperature on the first partition 400; when it is not necessary to open the first bypass branch 150, it can be closed, so that a portion of the air on the inlet side of the first heat exchanger 200 in the return air duct 110 is completely heated by the first heat exchanger 200 before entering the room, thereby improving energy efficiency.

[0089] It is understood that when the first regulating member 500 includes the first air valve 510 and the second air valve 520, the first temperature sensor 700 is simultaneously electrically connected to the first air valve 510 and the second air valve 520 to control the first air valve 510 and the second air valve 520 to move synchronously to open or close the first bypass branch 150.

[0090] The first preset temperature value can be obtained based on experience or based on multiple experiments.

[0091] In some embodiments, such as Figure 7 As shown, the air conditioner 10 also includes a first humidity sensor 800, which is fixed to the outer wall of the housing 100 and is used to detect the first actual humidity value of the condensation generated by the cooling energy radiated from the first partition 400 on the housing 100 to the housing 100. The first humidity sensor 800 is electrically connected to the first regulating member 500. When the first actual humidity value is lower than the first preset humidity value, the first regulating member 500 opens the first bypass branch 150. When the first actual humidity value is higher than the first preset humidity value, the first regulating member 500 closes the first bypass branch 150.

[0092] With the above settings, when the humidity on the casing 100 near the first partition 400 is too high, the first bypass branch 150 is opened to heat the first partition 400 and the casing 100, thereby preventing the continued generation of condensation.

[0093] It is understood that when the first regulating member 500 includes the first air valve 510 and the second air valve 520, the first humidity sensor 800 is simultaneously electrically connected to the first air valve 510 and the second air valve 520 to control the first air valve 510 and the second air valve 520 to move synchronously to open or close the first bypass branch 150.

[0094] The first preset humidity value can be obtained based on experience or based on multiple tests.

[0095] In some embodiments, the air conditioner 10 includes both a first temperature sensor 700 and a first humidity sensor 800. By utilizing the dual cooperation of the first temperature sensor 700 and the first humidity sensor 800, the movement of the first regulating member 500 is precisely controlled to open or close the first bypass branch 150, thereby better preventing the generation of condensation.

[0096] In some embodiments, for the convenience of controlling the second adjusting member 600, such as Figure 8 As shown, the air conditioner 10 also includes a second temperature sensor 710, which is disposed in the second bypass branch 160 and fixed on the second partition 410. The second temperature sensor 710 is used to detect the second actual temperature value on the second partition 410. The second temperature sensor 710 is electrically connected to the second regulating member 600.

[0097] When the second actual temperature value is lower than the second preset temperature value, the second regulating member 600 opens the second bypass branch 160; when the second actual temperature value is higher than the second preset temperature value, the second regulating member 600 closes the second bypass branch 160.

[0098] With the above configuration, the second temperature sensor 710 detects the temperature on the second partition 410, and controls the second regulating element 600 to open or close the second bypass branch 160 at appropriate times. Thus, when it is necessary to open the second bypass branch 160, it can be opened to increase the temperature on the second partition 410; when it is not necessary to open the second bypass branch 160, it can be closed, ensuring that a portion of the air on the intake side of the second heat exchanger 220 in the fresh air duct 120 is heated by the second heat exchanger 220 before entering the room, thereby improving energy efficiency.

[0099] It is understood that when the first regulating member 500 includes the third air valve 610 and the fourth air valve 620, the second temperature sensor 710 is electrically connected to both the third air valve 610 and the fourth air valve 620 simultaneously to control the third air valve 610 and the fourth air valve 620 to move synchronously to open or close the second bypass branch 160.

[0100] The second preset temperature value can be obtained based on experience or from multiple experiments.

[0101] In some embodiments, such as Figure 8 As shown, the air conditioner 10 also includes a second humidity sensor 810, which is fixed to the outer wall of the housing 100 and is used to detect the second actual humidity value of the condensation generated by the cooling energy radiated from the second partition 410 on the housing 100. The second humidity sensor 810 is electrically connected to the second regulating member 600. When the second actual humidity value is lower than the second preset humidity value, the second regulating member 600 opens the second bypass branch 160; when the second actual humidity value is higher than the second preset humidity value, the second regulating member 600 closes the second bypass branch 160.

[0102] With the above settings, when the humidity on the casing 100 near the second partition 410 is too high, the second bypass branch 160 is opened to heat the second partition 410 and the casing 100, thereby preventing the continued generation of condensation.

[0103] It is understood that when the second regulating member 600 includes the third air valve 610 and the fourth air valve 620, the second humidity sensor 810 is electrically connected to both the third air valve 610 and the fourth air valve 620 simultaneously to control the third air valve 610 and the fourth air valve 620 to move synchronously to open or close the second bypass branch 160.

[0104] The second preset humidity value can be obtained based on experience or from multiple tests.

[0105] In some embodiments, the air conditioner 10 includes a second temperature sensor 710 and a second humidity sensor 810. By utilizing the dual cooperation of the second temperature sensor 710 and the second humidity sensor 810, the movement of the second regulating member 600 is precisely controlled to open or close the second bypass branch 160, thereby better preventing the generation of condensation.

[0106] In some embodiments, the vertical projection of the first heat exchanger 200 onto the first partition 400 is within the range of the first partition 400.

[0107] By implementing the above configuration, more of the cooling energy from the first heat exchanger 200 is radiated onto the first partition 400, thus reducing the probability of the cooling energy from the first heat exchanger 200 radiating onto other parts of the air conditioner 10. This better solves the condensation problem caused by the cooling energy from the first heat exchanger 200.

[0108] In other embodiments, the vertical projection of the second heat exchanger 220 onto the second partition 410 is within the range of the second partition 410.

[0109] With the above configuration, more of the cooling energy from the second heat exchanger 220 is radiated onto the second partition 410, thus reducing the probability of the cooling energy from the second heat exchanger 220 radiating to other parts of the air conditioner 10. This better solves the condensation problem caused by the cooling energy from the second heat exchanger 220.

[0110] To ensure indoor atmospheric pressure balance, such as Figure 9 As shown, an exhaust duct 170 is also formed inside the housing 100. One end of the exhaust duct 170 is connected to the outside, and the other end of the exhaust duct 170 is connected to the inside. A third fan 180 is installed inside the exhaust duct 170. For example, the third fan 180 can be installed at the air outlet of the exhaust duct 170 (where the exhaust duct 170 is connected to the outside).

[0111] An exhaust duct 170 is installed inside the casing 100 to connect the indoor and outdoor environments. When enough fresh air enters the indoor environment, the third fan 180 can be activated to exhaust the indoor air to the outdoor environment, so as to balance the atmospheric pressure between the indoor and outdoor environments.

[0112] The exhaust duct 170 can be installed at one end that connects to the indoor space, such as a bathroom or kitchen, where polluted air is easily generated. When the third fan 180 is turned on, such polluted air can be exhausted to the outside through the exhaust duct 170, thus keeping the indoor air fresh.

[0113] Alternatively, the end of the exhaust duct 170 that connects to the indoor space can be located in a normal indoor location, such as the living room or bedroom. This application does not impose specific limitations on this, and the location can be determined according to actual needs.

[0114] Because the air temperature discharged from the exhaust duct 170 is relatively close to the indoor air temperature, therefore, Figure 10 As shown, the air conditioner 10 provided in this application also includes a total heat exchanger 900. The total heat exchanger 900 has a first heat exchange channel and a second heat exchange channel that are independent of each other. The first heat exchange channel is connected in series with the fresh air duct 120 and is located on the air inlet side of the second heat exchanger 220. The second heat exchange channel is connected in series with the exhaust air duct 170.

[0115] Since the first heat exchange channel is connected in series with the fresh air duct 120, fresh outdoor air enters the room through the first heat exchange channel. Similarly, since the second heat exchange channel is connected in series with the exhaust duct 170, indoor air passes through the second heat exchange channel as it passes through the exhaust duct 170. Furthermore, because heat exchange can occur between the first and second heat exchange channels, heat exchange can occur between the air flowing through the first and second heat exchange channels.

[0116] Through heat exchange, the temperature of the air exhausted to the outside is exchanged with the temperature of the fresh air entering the room, which can make full use of the energy in the air exhausted to the outside. After the air in the fresh air duct 120 passes through the first heat exchange channel, the temperature can be close to the indoor temperature. When the air with the reduced temperature passes through the second heat exchanger 220, the energy consumption of the second heat exchanger 220 can be reduced.

[0117] For example, in summer, the outdoor air temperature is high, while the indoor air temperature is low after cooling. When the outdoor air flows through the first heat exchange channel and the indoor air flows through the second heat exchange channel, heat exchange occurs between them. This results in the air temperature decreasing after passing through the first heat exchange channel, while the temperature of the air exhausted outdoors increases. Because the air temperature after passing through the first heat exchange channel is lower and closer to the indoor temperature, less energy is needed to lower the air temperature to the indoor air temperature when passing through the second heat exchanger 220, thus saving energy.

[0118] It is understandable that the first heat exchange channel is located on the air inlet side of the second heat exchanger 220, which means that the outdoor air flowing through the fresh air duct 120 will first pass through the first heat exchange channel and then through the second heat exchanger 220. That is, the air first undergoes heat exchange through the first heat exchange channel and then through the second heat exchanger 220.

[0119] The first heat exchange channel is connected in series with the fresh air duct 120, and the second heat exchange channel is connected in series with the exhaust air duct 170. The first heat exchange channel can be connected in series at one end of the air inlet of the fresh air duct 120, and the second heat exchange channel can be connected in series at one end of the air inlet or one end of the air outlet of the exhaust air duct 170.

[0120] Alternatively, the first heat exchange channel can be connected in series in the middle of the fresh air duct 120, and the second heat exchange channel can be connected in series in the middle of the exhaust air duct 170.

[0121] In some embodiments, in order to achieve air filtration, such as Figure 10 As shown, the air conditioner 10 also includes a plurality of air filters 910.

[0122] An air filter 910 is installed at the air inlet of the return air duct 110. The air filter 910 is used to filter and remove dust from the indoor air, thereby ensuring the cleanliness of the indoor air.

[0123] An air filter 910 is installed at the air inlet of the fresh air duct 120. The air filter 910 filters dust from the fresh air entering the room, so as to keep the fresh air entering the room from the outside clean.

[0124] An air filter 910 is installed in the exhaust duct 170. The air filter 910 filters out dust from the air exhausted to the outside, which can prevent the exhaust air from polluting the outdoor air.

[0125] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
