[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0050] An air conditioner 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The air conditioner 1 can be used to adjust the indoor ambient temperature. Specifically, the air conditioner 1 can be an integrated air conditioner 1, for example, a mobile air conditioner 1 or a window air conditioner 1.

[0051] The air conditioner 1 according to the embodiment of the present invention may include a first heat exchanging unit and a second heat exchanging unit.

[0052] like Figure 1 and Figure 4As shown, specifically, the first heat exchange unit includes a first heat exchanger 30 and a first fan assembly 201 , and the first fan assembly 201 includes a first wind wheel 2011 .

[0053] The second heat exchange unit includes a second heat exchanger 40 and a second fan assembly 202 . The second fan assembly 202 includes a second wind wheel 2021 .

[0054] One of the first heat exchange unit and the second heat exchange unit is a condenser unit, and the other of the first heat exchange unit and the second heat exchange unit is an evaporator unit. Specifically, one of the first heat exchanger 30 and the second heat exchanger 40 is an evaporator, and the other of the first heat exchanger 30 and the second heat exchanger 40 is a condenser. That is, the first heat exchanger 30 can be an evaporator and the first heat exchange unit is an evaporator unit, then the second heat exchanger 40 can be a condenser and the second heat exchange unit is a condenser unit; or the first heat exchanger 30 can be a condenser and the first heat exchange unit is a condenser unit, then the second heat exchanger 40 can be an evaporator and the second heat exchange unit is an evaporator unit.

[0055] Specifically, the air conditioner 1 can be a cooling-only type air conditioner 1 or a heating-and-cooling type air conditioner 1; when the air conditioner 1 is a cooling-only type air conditioner 1, the first heat exchanger 30 is an evaporator, the second heat exchanger 40 is a condenser, and the first heat exchanger 30 is used to provide cooling to the room to achieve cooling; when the air conditioner 1 is a heating-and-cooling type air conditioner 1, in cooling mode and dehumidification mode, the first heat exchanger 30 is an evaporator, the second heat exchanger 40 is a condenser, and in cooling mode, the first heat exchanger 30 is used to provide cooling to the room to achieve cooling, and in heating mode, the first heat exchanger 30 is a condenser, the second heat exchanger 40 is an evaporator, and in heating mode, the first heat exchanger 30 is used to provide heat to the room to achieve heating.

[0056] In cooling mode, the first fan assembly 201 drives the airflow to exchange heat with the first heat exchanger 30 to adjust the indoor ambient temperature, and the second fan assembly 202 drives the airflow to exchange heat with the second heat exchanger 40.

[0057] In the dehumidification mode, the first fan assembly 201 and / or the second fan assembly 202 drives at least part of the airflow after heat exchange with the first heat exchanger 30 to flow toward the second heat exchanger 40. That is, in the dehumidification mode, the first fan assembly 201 is in operation and the second fan assembly 202 is inoperable, thereby utilizing the first fan assembly 201 to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow toward the second heat exchanger 40; in the dehumidification mode, the first fan assembly 201 is inoperable and the second fan assembly 202 is in operation, thereby utilizing the second fan assembly 202 to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow toward the second heat exchanger 40; or, in the dehumidification mode, the first fan assembly 201 is in operation and the second fan assembly 202 is in operation, thereby utilizing the first fan assembly 201 and the second fan assembly 202 to jointly drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow toward the second heat exchanger 40.

[0058] Specifically, in dehumidification mode, because the first heat exchanger 30 functions as an evaporator, the airflow is cooled and dehumidified after exchanging heat with the first heat exchanger 30, producing condensed water to form a cold airflow. Because the second heat exchanger 40 functions as a condenser, at least a portion of the cold airflow flowing to the second heat exchanger 40 can be heated by the second heat exchanger 40. Heating the cold airflow by the second heat exchanger 40 increases its temperature. Thus, in dehumidification mode, the change in the indoor ambient temperature is minimal, or even nonexistent, ensuring a dehumidification effect in which the airflow that once again exchanges heat with the first heat exchanger 30 is cooled and dehumidified by the first heat exchanger 30. This can at least achieve the goal of dehumidification without cooling, further improving the dehumidification effect and making the dehumidification and cooling functions independent of each other.

[0059] It can be understood that when the air conditioner 1 is a heating and cooling type air conditioner, in the heating mode, the first fan assembly 201 drives the airflow to exchange heat with the first heat exchanger 30 to adjust the indoor ambient temperature, and the second fan assembly 202 drives the airflow to exchange heat with the second heat exchanger 40.

[0060] According to the air conditioner 1 of the embodiment of the present invention, by utilizing the first fan assembly 201 and / or the second fan assembly 202 to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40, the purpose of dehumidification without cooling can be achieved at least to a certain extent, which is beneficial to improving the dehumidification effect. The air conditioner 1 can independently realize the cooling function and the dehumidification function, and can better meet the user's usage needs.

[0061] In some embodiments of the present invention, Figure 2 and Figure 5As shown, the air conditioner 1 includes a housing 10, and the first heat exchange unit and the second heat exchange unit are located in the housing 10. Therefore, on the one hand, the first heat exchange unit and the second heat exchange unit are integrated into one housing 10, which makes the structure simpler and the appearance more beautiful.

[0062] According to some specific embodiments of the present invention, the housing 10 is made of plastic, which is helpful in reducing costs.

[0063] According to some embodiments of the present invention, at least one of the first fan assembly 201 and the second fan assembly 202 is rotatably disposed in the housing 10 to adjust the flow direction of the airflow. That is to say, only the first fan assembly 201 is rotatably arranged in the shell 10 as a whole, while the second fan assembly 202 is not rotatable as a whole; only the second fan assembly 202 is rotatably arranged in the shell 10 as a whole, while the first fan assembly 201 is not rotatable as a whole; or, the first fan assembly 201 and the second fan assembly 202 are respectively rotatably arranged in the shell 10, thereby, by at least one of the first fan assembly 201 and the second fan assembly 202 being rotatable in the shell 10, the direction of the airflow driven by the fan assembly can be adjusted, so that in the cooling mode, the first fan assembly 201 drives the airflow to exchange heat with the first heat exchanger 30, and the second fan assembly 202 drives the airflow to exchange heat with the second heat exchanger 40, while in the dehumidification mode, the first fan assembly 201 and / or the second fan assembly 202 drives at least part of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40.

[0064] Specifically, if Figure 1 and Figure 5 As shown, the first fan assembly 201 includes a first fan rotor 2011 and a first motor 2012. The first motor 2012 is used to drive the first fan rotor 2011 to rotate. When the first fan assembly 201 is rotatable relative to the housing 10, the extension direction of the central axis of the first fan rotor 2011 can be adjusted. The rotation of the first fan assembly 201 can thereby change the direction of the airflow driven by the first fan assembly 201. For example, if the first fan rotor 2011 is an axial flow fan, the first fan assembly 201 can be rotated until the central axis of the first fan rotor 2011 extends horizontally, thereby driving the airflow horizontally. The second fan assembly 202 includes a second fan rotor 2021 and a second motor 2022. The second motor 2022 is used to drive the second fan rotor 2021 to rotate. When the second fan assembly 202 is rotatable relative to the housing 10, the extension direction of the central axis of the second fan rotor 2021 can be adjusted. The rotation of the second fan assembly 202 can thereby change the direction of the airflow driven by the second fan assembly 202. For example, when the second wind wheel 2021 is an axial flow wind wheel, the second fan assembly 202 rotates until the central axis of the second wind wheel 2021 extends horizontally, and then the second wind wheel 2021 can drive the airflow to move horizontally.

[0065] In some embodiments of the present invention, the first fan assembly 201 includes a first rotor bracket, a first rotor 2011 rotatably mounted on the first rotor bracket, a first motor 2012 mounted on the first rotor bracket and connected to the first rotor 2011 for driving the first rotor 2011 to rotate, and the first rotor bracket rotatably mounted within the housing 10. The first fan assembly 201 can be rotated relative to the housing 10 by rotating the first rotor bracket relative to the housing 10. This results in a simple structure and improved reliability.

[0066] In some embodiments of the present invention, the second fan assembly 202 includes a second rotor bracket, a second rotor 2021 rotatably mounted on the second rotor bracket, a second motor 2022 mounted on the second rotor bracket and connected to the second rotor 2021 for driving the second rotor 2021 to rotate, and the second rotor bracket rotatably mounted within the housing 10. The second fan assembly 202 can be rotated relative to the housing 10 by rotating the second rotor bracket relative to the housing 10. This results in a simple structure and improved reliability.

[0067] According to some embodiments of the present invention, Figure 1-Figure 2 As shown, the housing 10 has an air duct a, and the first heat exchange unit and the second heat exchange unit are disposed in the air duct a. Thus, the first heat exchange unit and the second heat exchange unit share the air duct a, and the first heat exchanger 30, the second heat exchanger 40, the first fan assembly 201, and the second fan assembly 202 are all located in the air duct a. Consequently, the evaporator and the condenser are both located in the same air duct a, resulting in a simpler and more compact structure. There is no need to provide separate air ducts a corresponding to the evaporator and the condenser, respectively. This is beneficial for improving production efficiency and reducing costs. Furthermore, the fan assembly, the first heat exchanger 30, and the second heat exchanger 40 share the air duct a, further simplifying the structure and making it more compact. This is beneficial for improving production efficiency and reducing costs, and can simplify the structure of the air conditioner 1.

[0068] According to some embodiments of the present invention, the housing 10 is provided with an air inlet d, which is connected to the air duct a; the housing 10 is provided with a first air outlet e, which is connected to the air duct a; the housing 10 is provided with a second air outlet f, which is connected to the air duct a. In other words, the housing 10 is provided with an air inlet d, a first air outlet e, and a second air outlet f, and the first air outlet e, the air inlet d, and the second air outlet f are all connected to the air duct a. This facilitates the circulation of air between the housing 10 and the indoor environment where the air conditioner 1 is located.

[0069] The first heat exchanger 30 and the second heat exchanger 40 are arranged opposite to each other, the first air outlet e is located on the side of the first heat exchanger 30 away from the second heat exchanger 40, the second air outlet f is located on the side of the second heat exchanger 40 away from the first heat exchanger 30, the first fan assembly 201 and the second fan assembly 202 are located between the first heat exchanger 30 and the second heat exchanger 40, and the first fan assembly 201 is located between the second fan assembly 202 and the first heat exchanger 30. Thus, in the first direction (for example Figure 1-Figure 2 In the left and right directions in the figure, the first air outlet e, the first heat exchanger 30, the first fan assembly 201, the second fan assembly 202, the second heat exchanger 40 and the second air outlet f are arranged in sequence, and in the first direction, the air inlet d is located between the first heat exchanger 30 and the second heat exchanger 40, so that the air inlet d and the first fan assembly 201 and the second fan assembly 202 in the second direction (for example Figure 1-Figure 2 Relative to the up and down directions).

[0070] An opening and closing member 101 is provided at the air inlet d, and the opening and closing member 101 can be used to open or close the air inlet d. For example, when the air conditioner 1 is a cooling-only type air conditioner 1, the opening and closing member 101 opens the air inlet d when the air conditioner 1 is in cooling mode, and closes the air inlet d when the air conditioner 1 is in dehumidification mode. For another example, when the air conditioner 1 is a cooling and heating type air conditioner 1, the opening and closing member 101 opens the air inlet d when the air conditioner 1 is in cooling mode and heating mode, and closes the air inlet d when the air conditioner 1 is in dehumidification mode.

[0071] Specifically, in the cooling mode, the opening and closing member 101 opens the air inlet d, and the first wind wheel 2011 and the second wind wheel 2021 rotate forward to drive the air flow from the air inlet d into the air duct a. Driven by the first wind wheel 2011, a part of the air flow entering the air duct a exchanges heat with the first heat exchanger 30 and is discharged from the first air outlet e. The remaining air flow entering the air duct a exchanges heat with the second heat exchanger 40 under the drive of the second wind wheel 2021 and is discharged from the second air outlet f.

[0072] In the dehumidification mode, the opening and closing member 101 closes the air inlet d, and the first wind wheel 2011 rotates in the reverse direction and / or the second wind wheel 2021 rotates in the forward direction, driving the airflow from the first air outlet e into the air duct a and out of the second air outlet f. Specifically, in the dehumidification mode, the airflow entering the air duct a from the first air outlet e first exchanges heat with the first heat exchanger 30. Since the first heat exchanger 30 is an evaporator, the airflow is cooled and dehumidified after passing through the first heat exchanger 30, generating condensed water to form a cold airflow. The cold airflow flows to the second heat exchanger 40 and is heated by the second heat exchanger 40, thereby preventing the temperature of the airflow discharged from the second air outlet f from decreasing, thereby achieving the purpose of dehumidification without cooling. In particular, when the second air outlet f is connected to the outside, the airflow discharged from the second air outlet f is discharged to the outside, which will not affect the indoor ambient temperature.

[0073] In some embodiments of the present invention, the first wind wheel 2011 and the second wind wheel 2021 are both axial flow wind wheels, which not only has a simple structure but also has low cost.

[0074] According to some embodiments of the present invention, the first fan assembly 201 and the second fan assembly 202 are each rotatably disposed within the air duct a. Specifically, in dehumidification mode, the first fan assembly 201 and the second fan assembly 202 are in a first operating position. In the first operating position, the rotation centerline of the first fan wheel 2011 is parallel to or collinear with the rotation centerline of the second fan wheel 2021. The rotation centerline of the first fan wheel 2011 extends in the direction of the gap between the first heat exchanger 30 and the second heat exchanger 40, i.e., in the aforementioned one direction. Therefore, when the first fan wheel 2011 rotates in the reverse direction and / or the second fan wheel 2021 rotates in the forward direction, more airflow can be driven into the air duct a from the first air outlet e and flow along the axial direction of the first fan wheel 2011, thereby increasing air volume and improving dehumidification efficiency.

[0075] In the cooling mode, the first fan assembly 201 and the second fan assembly 202 are in the second working position. In the second working position, the rotation center line of the first wind wheel 2011 and the rotation center line of the second wind wheel 2021 are both inclined toward the air inlet d in the direction toward the center of the shell 10, so as to facilitate the first wind wheel 2011 and the second wind wheel 2021 to drive the airflow from the air inlet d into the air duct a, and respectively drive the airflow in the air duct a to flow to their respective corresponding heat exchangers, which helps to increase the driving effect of the two fan assemblies on the airflow, increase the air volume, and avoid airflow interference.

[0076] In some embodiments of the present invention, Figure 1As shown, the angle β between the rotation centerline of the first wind wheel 2011 and the rotation centerline of the second wind wheel 2021 ranges from 200° to 250°. For example, β is 205°, 206°, 207°, 208°, 209°, 210°, 212°, 215°, 217°, 220°, 222°, 224°, 225°, 228°, 230°, 232°, 235°, 236°, 238°, 240°, 242°, 245°, 248°, or 250°. Thus, in cooling mode, the first wind wheel 2011 and the second wind wheel 2021 drive airflow from the air inlet d into the air duct a, and respectively drive the airflow in the air duct a to flow to their respective heat exchangers, thereby increasing the driving effect of the two fan assemblies on the airflow and improving the air volume.

[0077] According to some embodiments of the present invention, housing 10 defines a compressor mounting cavity, which is separated from air duct a. Air conditioner 1 includes a compressor, which is disposed within the compressor mounting cavity. Specifically, the compressor includes an exhaust port and a return port. The exhaust port is connected to one of the first heat exchanger 30 and the second heat exchanger 40, and the return port is connected to the other of the first heat exchanger 30 and the second heat exchanger 40. The first heat exchanger 30 and the second heat exchanger 40 are connected via a throttling element. The specific connection relationship between the compressor, evaporator, condenser, and throttling element, as well as the refrigerant circulation direction, are well known to those skilled in the art and will not be described in detail here.

[0078] Specifically, a mounting groove is provided on the bottom wall of the compressor mounting cavity, the shock-absorbing sleeve is disposed within the mounting groove, and the top wall of the shock-absorbing sleeve has a shock-absorbing groove, with the bottom of the compressor located within the shock-absorbing groove. Thus, on the one hand, by disposing the shock-absorbing sleeve at the bottom of the compressor, the compressor can be directly placed within the shock-absorbing groove, resulting in a simple structure and convenient installation. On the other hand, by disposing the shock-absorbing sleeve within the mounting groove, the mounting groove can be used not only to locate the mounting position of the shock-absorbing sleeve, but also to limit the position of the shock-absorbing sleeve, thereby preventing the shock-absorbing sleeve from shifting or deviating due to vibration during the vibration of the compressor, thereby affecting the shock-absorbing effect.

[0079] According to some embodiments of the present invention, the remaining space of the compressor mounting cavity, excluding the space occupied by the compressor, is filled with a flexible filler. This not only secures the compressor securely, but also reduces compressor vibration, thereby reducing compressor noise.

[0080] Optionally, the flexible filler includes at least one of rubber particles, silicone particles, and a foaming agent. That is, the flexible filler may be comprised solely of rubber particles, solely of silicone particles, or solely of a foaming agent; the flexible filler may include both rubber particles and silicone particles; the flexible filler may include both rubber particles and a foaming agent; the flexible filler may include both silicone particles and a foaming agent; or the flexible filler may include all three of these agents simultaneously. Foaming agents have a good filling effect, are low in density, lightweight, and contain a large number of voids, thereby absorbing compressor noise. Rubber and silicone particles have excellent elasticity, converting compressor vibration into elastic potential energy, thereby reducing compressor vibration and noise. Furthermore, they are low in cost, thereby lowering production costs.

[0081] According to some embodiments of the present invention, an annular stopper plate is provided on the bottom wall of the compressor mounting cavity. The stopper plate and the bottom wall of the compressor mounting cavity define a mounting groove. This provides a simple structure and facilitates processing. Of course, the present invention is not limited to this embodiment. In other embodiments, the bottom wall of the compressor mounting cavity may be recessed downward to form the mounting groove.

[0082] According to some embodiments of the present invention, Figure 4-Figure 5 As shown, the housing 10 has a first air duct a1 and a second air duct a2 that are independent of each other. That is, the first air duct a1 and the second air duct a2 are provided in the housing 10, and the first air duct a1 and the second air duct a2 are independent of each other and not connected. For example, the first air duct a1 and the second air duct a2 are spaced apart in the second direction (e.g., the vertical direction).

[0083] The housing 10 is provided with a first air inlet d1 and a first air outlet e. Both the first air inlet d1 and the first air outlet e are connected to the first air duct a1, and the first heat exchange unit is located within the first air duct a1. Thus, the first fan assembly 201 can drive air from the first air inlet d1 into the first air duct a1 for heat exchange with the first heat exchanger 30, and then be discharged from the first air outlet e, thereby regulating the indoor ambient temperature.

[0084] The housing 10 is provided with a second air inlet d2 and a second air outlet f. Both the second air inlet d2 and the second air outlet f are connected to the second air duct a2, and the second heat exchange unit is located within the second air duct a2. Thus, the second fan assembly 202 can drive air from the second air inlet d2 into the second air duct a2 for heat exchange with the second heat exchanger 40, and then be discharged through the second air outlet f.

[0085] In dehumidification mode, Figure 5As shown, the first fan assembly 201 and the second fan assembly 202 drive part of the airflow discharged from the first air outlet e to flow to the second heat exchanger 40 through the second air inlet d2. Specifically, in the dehumidification mode, since the first heat exchanger 30 is an evaporator and the second heat exchanger 40 is a condenser, the first fan assembly 201 drives the air flow from the first air inlet d1 into the first air duct a1 to exchange heat with the first heat exchanger 30 to achieve cooling and dehumidification and form a cold air flow, and then discharged from the first air outlet e. Since the first air outlet e and the second air inlet d2 are located on the same side wall of the shell 10 and the two are adjacent, part of the cold air flow discharged from the first air outlet e, under the further drive of the second fan assembly 202, passes through the second air inlet d2 into the second air duct a2 and is heated by the second heat exchanger 40, and then discharged from the second air outlet f. Therefore, in the dehumidification mode, the air conditioner 1 has a smaller regulating effect on the indoor ambient temperature, which is conducive to achieving the purpose of dehumidification without cooling at least to a certain extent, thereby improving the dehumidification effect. In particular, when the second air outlet f is connected to the outdoors, the air flow discharged from the second air outlet f is discharged to the outdoors, and has less impact on the indoor ambient temperature.

[0086] According to some embodiments of the present invention, the first wind wheel 2011 is an axial flow wind wheel, the first fan assembly 201 is arranged adjacent to the first air outlet e, and the first fan assembly 201 is rotatable in the spacing direction between the first air outlet e and the second air inlet d2 to switch between the first working state and the second working state. For example, the first air outlet e and the second air inlet d2 are spaced apart in the second direction (the up and down direction in the figure), and the first fan assembly 201 is rotatable in the up and down direction to switch between the first working state and the second working state. In the dehumidification mode, the first fan assembly 201 is in the first working state. In the first working state, in the flow direction of the airflow, the rotation centerline of the first wind wheel 2011 is inclined toward the direction close to the second air inlet d2 (such as Figure 5 ), so as to supply air toward the second air inlet d2. That is, in the dehumidification mode, the first fan assembly 201 can be controlled to rotate toward the direction close to the second air inlet d2, so that the rotation center line of the first wind wheel is tilted toward the direction close to the second air inlet d2 in the flow direction of the air flow (as shown in FIG. Figure 5 ), so as to supply air toward the second air inlet d2, so that the angle α between the rotation center line of the first wind wheel 2011 and the plane where the second air inlet d2 is located is an acute angle, which is conducive to the wind discharged from the first air outlet e being more sucked into the second air inlet d2.

[0087] Optionally, in cooling mode, to improve the cooling effect, the first fan assembly 201 is in a second operating state, in which the angle α between the rotation centerline of the first impeller 2011 and the plane where the second air inlet d2 is located is not less than 90°. For example, in cooling mode, the value of α is between 90° and 170°, for example, α is 90°, 95°, 99°, 100°, 102°, 108°, 110°, 115°, 121°, 120°, 130°, 128°, 125°, 132°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, or 162°.

[0088] In some embodiments of the present invention, an air outlet frame 106 surrounding the first air outlet e is provided on the outer side of the shell 10, and the end of the air outlet frame 106 opposite to the first air outlet e defines a first sub-air outlet e1, and a second sub-air outlet e2 is provided on the side of the peripheral wall of the air outlet frame 106 adjacent to the second air inlet d2. An air guide 107 is rotatably provided at the first sub-air outlet e1, and the air guide 107 is used to open or close the first sub-air outlet e1. In the dehumidification mode, the air guide 107 closes the first sub-air outlet e1, so that the air flow blown out from the first air outlet e is discharged from the second sub-air outlet e2, which is conducive to the air flow blown out from the first air outlet e passing through the second sub-air outlet e2 and entering the second air inlet d2 as much as possible, thereby achieving the purpose of dehumidification without cooling to a certain extent, thereby improving the dehumidification effect; in the cooling mode, the air guide 107 opens the first sub-air outlet e1, thereby facilitating cooling of the room.

[0089] In some embodiments of the present invention, the second heat exchanger 40 is disposed adjacent to the second air inlet d2 , thereby improving the heating effect of the second heat exchanger 40 on the airflow discharged from the first air outlet e, achieving the purpose of dehumidification without cooling, at least to a certain extent, thereby improving the dehumidification effect.

[0090] According to some embodiments of the present invention, first heat exchanger 30 is an evaporator, and second heat exchanger 40 is a condenser, i.e., air conditioner 1 is a cooling-only air conditioner 1. Air conditioner 1 includes a water tray disposed within housing 10 for collecting condensed water from the evaporator. Thus, the provision of a water tray prevents condensed water from the evaporator from dripping freely, thereby preventing damage to electronic control components and preventing it from dripping onto the ground outside housing 10, thereby improving the user experience.

[0091] Specifically, the air conditioner 1 includes a water pump assembly for pumping condensed water from the water pan to the condenser. Thus, condensed water from the evaporator can be collected in the water pan and then pumped to the condenser by the water pump assembly. The condenser heats the condensed water, causing it to absorb heat and evaporate, thereby increasing the humidity of the environment and the heat exchange efficiency of the condenser. This also allows for the reuse of the condensed water, eliminating the need for a separate drainage line and preventing the discharge of condensed water, which could negatively impact the user experience.

[0092] Optionally, an air outlet grille is provided at the second air outlet f, thereby improving safety and preventing hands or the like from reaching into the housing 10 through the second air outlet f.

[0093] Specifically, the air outlet grille includes a plurality of first grille bars and a plurality of second grille bars, and the plurality of first grille bars and the plurality of second grille bars are arranged in a staggered manner, thereby simplifying the structure.

[0094] Furthermore, a plurality of first grid bars are arranged in parallel, and a plurality of second grid bars are arranged in parallel, thereby simplifying the structure and facilitating processing and manufacturing.

[0095] Optionally, the air outlet grille is an integrally formed piece. This integral structure not only ensures the structural and performance stability of the air outlet grille, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, greatly improving the assembly efficiency of the air outlet grille and ensuring the reliability of the air outlet grille connection. Furthermore, the integrally formed structure has higher overall strength and stability, making assembly easier and extending its service life.

[0096] According to some further embodiments of the present invention, the air outlet grille is detachably mounted at the second air outlet f via a snap-fit ​​structure, thereby facilitating cleaning, maintenance, and replacement of the air outlet grille.

[0097] In some embodiments of the present invention, Figure 6 As shown, at least one of the first heat exchanger 30 and the second heat exchanger 40 is formed in a U-shape extending along the circumference of the housing 10. In other words, the first heat exchanger 30 is formed in a U-shape extending along the circumference of the housing 10, the second heat exchanger 40 is formed in a U-shape extending along the circumference of the housing 10, or both the first heat exchanger 30 and the second heat exchanger 40 are formed in a U-shape extending along the circumference of the housing 10. This helps increase the heat exchange area, facilitates more airflow through the corresponding heat exchanger, and improves heat exchange efficiency.

[0098] According to some embodiments of the present invention, Figure 1-Figure 2As shown, the first heat exchanger 30 is located at the inner end of the first air outlet e, and the second heat exchanger 40 is located at the inner end of the second air outlet f. Therefore, in the cooling mode, the airflow after heat exchange with the first heat exchanger 30 is discharged from the first air outlet e, and the airflow after heat exchange with the second heat exchanger 40 is discharged from the second air outlet f. The structure is simple and avoids interference between the airflows. Of course, the present invention is not limited to this. In some embodiments of the present invention, such as Figure 4-Figure 5 As shown, the first heat exchanger 30 is located at the inner end of the first air inlet d1 , and the second heat exchanger 40 is located at the inner end of the second air inlet d2 .

[0099] According to some embodiments of the present invention, at least one of the first heat exchanger 30 and the second heat exchanger 40 is detachably connected to the housing 10. That is, the first heat exchanger 30 is detachably connected to the housing 10, the second heat exchanger 40 is detachably connected to the housing 10, or both the first heat exchanger 30 and the second heat exchanger 40 are detachably connected to the housing 10. This facilitates maintenance and replacement of the heat exchangers.

[0100] Specifically, at least one of the first heat exchanger 30 and the second heat exchanger 40 is detachably connected to the housing 10 via fasteners. That is, the first heat exchanger 30 is detachably connected to the housing 10 via fasteners, the second heat exchanger 40 is detachably connected to the housing 10 via fasteners, or both the first heat exchanger 30 and the second heat exchanger 40 are detachably connected to the housing 10 via fasteners. This facilitates disassembly and enhances connection reliability.

[0101] The following describes a control method of the air conditioner 1 according to an embodiment of the present invention. The air conditioner 1 includes at least a cooling mode and a dehumidification mode.

[0102] Reference Figure 7 and Figure 9 As shown, the control method of the air conditioner 1 according to the embodiment of the present invention includes the following steps:

[0103] Receive user instructions.

[0104] Specifically, the user can input the corresponding command information on the remote control, or the user can input the corresponding command information on the display panel of the air conditioner 1, or the user can input the corresponding command information on a mobile terminal such as an APP on a mobile phone. There is a signal interaction between the mobile terminal and the air conditioner 1 so that the air conditioner 1 receives the corresponding command information.

[0105] If the instruction is to turn on the dehumidification mode, the first wind wheel 2011 and / or the second wind wheel 2021 are controlled to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect.

[0106] If the instruction is to start the cooling mode, the first wind wheel 2011 and the second wind wheel 2021 are controlled to rotate forward.

[0107] According to the air conditioner 11 of the embodiment of the present invention, in the dehumidification mode, the first wind wheel 2011 and / or the second wind wheel 2021 are controlled to drive at least part of the air flow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect.

[0108] According to some embodiments of the present invention, if the instruction is to start the dehumidification mode, the step of controlling the first wind wheel 2011 and / or the second wind wheel 2021 to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40 specifically includes:

[0109] The indoor humidity Φ1 of the environment where the air conditioner 1 is located is obtained.

[0110] Specifically, the indoor ambient humidity can be obtained using a humidity sensor. It should be understood that the humidity sensor can be integrated into the air conditioner 1 or placed indoors, that is, separate from the air conditioner. If the humidity sensor is set separately from the air conditioner 1, the humidity sensor can communicate with the controller in the air conditioner 1 via wired or wireless communication.

[0111] The indoor environment humidity Φ1 is compared with a set value Φ, wherein the set value Φ can be a value set when the air conditioner 1 leaves the factory, or can be a value set by the user according to actual needs.

[0112] If Φ1 is greater than Φ, it indicates that the indoor humidity is high and dehumidification is required. In this case, the compressor can be controlled to operate at the first target frequency P1 and the first wind wheel 2011 and / or the second wind wheel 2021 can be controlled to drive at least a portion of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40. Specifically, in the dehumidification mode, since the first heat exchanger 30 is an evaporator, the airflow is cooled and dehumidified after heat exchange with the first heat exchanger 30, generating condensed water to form a cold airflow. Since the second heat exchanger 40 is a condenser, at least a portion of the cold airflow flowing to the second heat exchanger 40 can be heated by the second heat exchanger 40. The temperature of the cold airflow is increased after being heated by the second heat exchanger 40. In this way, in the dehumidification mode, the change to the indoor ambient temperature is small or even non-existent, ensuring the dehumidification effect of the airflow that once again participates in heat exchange with the first heat exchanger 30 being cooled and dehumidified by the first heat exchanger 30. In this way, the purpose of dehumidification without cooling can be achieved at least to a certain extent, which is more conducive to improving the dehumidification effect and making the dehumidification function and the refrigeration function independent of each other.

[0113] Specifically, when the air conditioner 1 includes the above-mentioned opening and closing component 101, if Φ1 is greater than Φ, the opening and closing component 101 is controlled to close the air inlet d, the first wind wheel 2011 is controlled to rotate in the reverse direction at the first speed n1, and the second wind wheel 2021 is controlled to rotate in the forward direction at the second speed n2, thereby facilitating the circulation of airflow.

[0114] When the shell 10 of the air conditioner 1 includes the above-mentioned first air duct a1 and second air duct a2, the control method of the air conditioner 1 includes: if Φ1 is greater than Φ, controlling the compressor to operate at the first target frequency P1, and controlling the first wind wheel 2011 to rotate at the first speed n1, and controlling the second wind wheel 2021 to rotate at the second speed n2 to drive part of the airflow discharged from the first air outlet e to flow to the second heat exchanger 40 through the second air inlet d2, thereby facilitating the circulation of the airflow.

[0115] According to the air conditioner 11 of an embodiment of the present invention, by comparing the obtained indoor ambient humidity Φ1 of the environment where the air conditioner 11 is located with the set value Φ, when Φ1 is greater than Φ, the compressor is controlled to operate at the first target frequency P1 and the first wind wheel 2011 and / or the second wind wheel 2021 are controlled to drive at least part of the airflow after heat exchange with the first heat exchanger 30 to flow to the second heat exchanger 40, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect.

[0116] Optionally, the first target frequency may be the rated frequency of the compressor, thereby further improving the dehumidification effect.

[0117] In some embodiments of the present invention, after controlling the compressor to operate at the first target frequency P1, controlling the opening and closing member 101 to close the air inlet d, controlling the first wind wheel 2011 to rotate in the reverse direction at the first speed n1, and controlling the second wind wheel 2021 to rotate in the forward direction at the second speed n2, the air inlet temperature T3 at the first air outlet e, the air outlet temperature T1 of the evaporator, and the air outlet temperature T2 of the condenser are detected. Specifically, the air inlet temperature T3 at the first air outlet e, the air outlet temperature T1 of the evaporator, and the air outlet temperature T2 of the condenser can be obtained using temperature sensors. For example, Figure 1-Figure 2 As shown, a first temperature sensor 102 is provided at the first air outlet e, a second temperature sensor 103 is provided on the surface of the first heat exchanger 30 facing the second heat exchanger 40, and a third temperature sensor 104 is provided on the surface of the second heat exchanger 40 facing away from the first heat exchanger 30. The first temperature sensor 102 is used to obtain the inlet air temperature at the first air outlet e in the dehumidification mode, the second temperature sensor 103 is used to obtain the outlet air temperature T1 of the evaporator in the dehumidification mode, and the third temperature sensor 104 is used to obtain the outlet air temperature T2 of the condenser in the dehumidification mode.

[0118] The cold air volume q1 of the evaporator is generated according to the first rotational speed n1 of the first wind wheel 2011, and the hot air volume q2 of the condenser is generated according to the second rotational speed n2 of the second wind wheel 2021; the actual cooling capacity Q1 of the evaporator is generated according to the air inlet temperature T3 at the first air outlet e, the air outlet temperature T1 of the evaporator and the cold air volume q1 of the evaporator, and the actual heating capacity Q2 of the condenser is generated according to the air outlet temperature T1 of the evaporator, the air outlet temperature T2 of the condenser and the hot air volume q2 of the condenser; the air dew point temperature Td is generated according to the actual cooling capacity Q1 of the evaporator, the actual cooling capacity Q2 of the condenser, the cold air volume q1 of the evaporator and the hot air volume q2 of the condenser.

[0119] Comparing the air dew point temperature Td with the evaporator outlet temperature T1, if T1 is greater than Td, indicating that the indoor humidity is still high, the speed of the first impeller 2011 is controlled to decrease; or the speed of the second impeller 2021 is controlled to decrease; and / or the frequency of the compressor is controlled to increase. This increases the difference between the evaporator outlet temperature and the condenser outlet temperature, further improving the dehumidification effect.

[0120] In some embodiments of the present invention, if T1 is less than or equal to Td, the current operation may be maintained until a user instruction to exit dehumidification mode or enter cooling mode is received, and then the dehumidification mode is exited. Alternatively, if T1 is less than or equal to Td, the dehumidification mode is directly exited or the cooling mode is directly entered.

[0121] According to some embodiments of the present invention, when the first fan assembly 201 and the second fan assembly 202 are respectively rotatably arranged in the air duct a, the control method of the air conditioner 1 includes: if Φ1 is greater than Φ, controlling the first fan assembly 201 and the second fan assembly 202 to be in the first working position, so as to drive more airflow from the first air outlet e into the air duct a and flow along the axial direction of the first wind wheel 2011, thereby increasing the air volume and improving the dehumidification efficiency.

[0122] According to some embodiments of the present invention, when first fan assembly 201 is rotatable in the direction of the interval between first air outlet e and second air inlet d2, a control method for air conditioner 1 includes: if Φ1 is greater than Φ, controlling first fan assembly 201 to rotate toward second air inlet d2 so that the angle α between the rotation centerline of first fan wheel 2011 and the plane containing second air inlet d2 is α1. This facilitates drawing more cold air into second air duct a2 for heating by second heat exchanger 40, further improving the dehumidification effect.

[0123] According to some embodiments of the present invention, after controlling the compressor to operate at a first target frequency P1, controlling the first impeller 2011 to rotate at a first speed n1, and controlling the second impeller 2021 to rotate at a second speed n2 to drive a portion of the airflow exhausted from the first air outlet e to flow to the second heat exchanger 40 via the second air inlet d2, the inlet air temperature T3 at the first air inlet d1, the outlet air temperature T1 of the evaporator, the outlet air temperature T2 of the condenser, and the inlet air temperature T4 at the second air inlet d2 are detected. Specifically, the inlet air temperature T3 at the first air inlet d1, the outlet air temperature T1 of the evaporator, the outlet air temperature T2 of the condenser, and the inlet air temperature T4 at the second air inlet d2 can be obtained using a temperature sensor. For example, a first temperature detection sensor is provided at the first air inlet d1, a second temperature detection sensor 108 is provided on the air outlet surface of the first heat exchanger 30, a third temperature detection sensor is provided at the second air inlet d2, and a fourth temperature detection sensor 109 is provided at the air outlet surface of the second heat exchanger 40. The first temperature detection sensor can obtain the inlet air temperature at the first air inlet d1, the second temperature detection sensor 108 can detect the outlet air temperature of the first heat exchanger 30, the third temperature detection sensor can be used to obtain the inlet air temperature at the second air inlet d2, and the fourth temperature detection sensor 109 can be used to obtain the temperature of the air outlet surface of the second heat exchanger 40.

[0124] The cold air volume q1 of the evaporator is generated according to the first rotation speed n1 of the first wind wheel 211, and the hot air volume q2 of the condenser is generated according to the second rotation speed n2 of the second wind wheel 221; the actual cooling capacity Q1 of the evaporator is generated according to the air inlet temperature T3 at the first air inlet d1, the air outlet temperature T1 of the evaporator, and the cold air volume q1 of the evaporator, and the actual heating capacity Q2 of the condenser is generated according to the air inlet temperature T4 at the second air inlet d2, the air outlet temperature T2 of the condenser, and the hot air volume q2 of the condenser; the actual cooling capacity Q1 of the evaporator and the actual The cooling capacity Q2, the cold air volume q1 of the evaporator, and the hot air volume q2 of the condenser generate the air dew point temperature Td; the air dew point temperature Td is compared with the air outlet temperature T1 of the evaporator; if T1 is greater than Td, the first fan assembly 201 is controlled to rotate further toward the second air inlet so that the angle α between the rotation centerline of the first fan wheel 2011 and the plane where the second air inlet d2 is located is reduced; and / or the speed of the first fan wheel 2011 is controlled to decrease; and / or the speed of the second fan wheel 2021 is controlled to decrease; and / or the frequency of the compressor is controlled to increase. In other words, if T1 is greater than Td, at least one of the rotation angle of the first fan assembly 201, the speed of the first fan wheel 2011, the speed of the second fan wheel 2021, and the frequency of the compressor can be adjusted, that is, one, two, three, or all of them can be adjusted.

[0125] In some embodiments of the present invention, when T1 is greater than Td, and after adjusting at least one of the rotation angle of the first fan assembly 201, the speed of the first wind wheel 2011, the speed of the second wind wheel 2021 and the frequency of the compressor, the process returns to the step of repeatedly detecting the inlet air temperature T3 at the first air inlet d1, the outlet air temperature T1 of the evaporator, the outlet air temperature T2 of the condenser, and the inlet air temperature T4 at the second air inlet d2 and executes them in sequence. If it is detected again that T1 is greater than Td, the first fan assembly 201 is further controlled to rotate further toward the second air inlet so that the angle between the rotation center line of the first wind wheel 2011 and the second air inlet d2 increases; and / or the speed of the first wind wheel 2011 is controlled to decrease; and / or the speed of the second wind wheel 2021 is controlled to decrease; and / or the frequency of the compressor is controlled to increase, until it is detected that T1 is less than or equal to Td, and the dehumidification mode is exited.

[0126] It is understood that during the repeated execution, if T1 is greater than Td, different parameters can be adjusted each time. For example, after detecting that T1 is greater than Td for the first time, the first fan assembly 201 is controlled to rotate further toward the second air inlet so that the angle between the rotation center line of the first wind wheel 2011 and the plane where the second air inlet d2 is located is reduced, and then the process returns to the step of repeatedly detecting the inlet air temperature T3 at the first air inlet d1, the outlet air temperature T1 of the evaporator, the outlet air temperature T2 of the condenser, and the inlet air temperature T4 at the second air inlet d2 and executes them in sequence. If it is detected again that T1 is greater than Td, the speed of the first wind wheel 2011 is controlled to decrease, the speed of the second wind wheel 2021 is controlled to decrease, and the frequency of the compressor is controlled to increase.

[0127] In some embodiments of the present invention, when an air guide 107 is provided at the first sub-outlet e1, if Φ1 is greater than Φ, the air guide 107 is controlled to close the first sub-outlet e1. This facilitates more cold air to be drawn into the second air duct a2 for heating by the second heat exchanger 40, further improving the dehumidification effect.

[0128] According to some embodiments of the present invention, Figure 8As shown, when the air conditioner 1 includes the above-mentioned opening and closing member 101, if the instruction is to turn on the cooling mode, the step of controlling the first wind wheel 2011 and the second wind wheel 2021 to rotate forward specifically includes: obtaining the indoor ambient temperature T0 of the environment in which the air conditioner 1 is located. Specifically, the indoor ambient temperature can be obtained based on the temperature sensor. It should be understood that the temperature sensor can be integrated on the air conditioner 1 or placed indoors, that is, separated from the air conditioner. If the temperature sensor is set separately from the air conditioner 1, the temperature sensor can communicate with the controller in the air conditioner 1 through wired communication or wireless communication. For example, a fourth temperature sensor 105 is provided at the air inlet d, and the fourth temperature sensor 105 is used to obtain the indoor ambient temperature T0 in the cooling mode.

[0129] The indoor ambient temperature T0 is compared with a preset value T; wherein the preset value T may be a value set when the air conditioner 1 leaves the factory, or a value set by the user according to actual needs.

[0130] If T0 is greater than T, the opening and closing member 101 is controlled to open the air inlet d, controlling the compressor to operate at the second target frequency and the first and second wind wheels 2011, 2021 to rotate forward. Consequently, the first and second wind wheels 2011, 2021 drive airflow from the air inlet d into the air duct a. A portion of the airflow entering the air duct a, driven further by the first wind wheel 2011, exchanges heat with the first heat exchanger 30 and is discharged through the first air outlet e. Another portion of the airflow entering the air duct a, driven further by the second wind wheel 2021, exchanges heat with the second heat exchanger 40 and is discharged through the second air outlet f, thereby achieving cooling.

[0131] Optionally, the second target frequency is the same as the first target frequency, thereby simplifying the control method. Of course, it is understandable that the second target frequency may also be different from the first target frequency.

[0132] Optionally, the second target frequency is a rated frequency, thereby improving the cooling effect.

[0133] In some embodiments of the present invention, when the first fan assembly 201 and the second fan assembly 202 are rotatably disposed in the air duct a, the control method of the air conditioner 1 includes controlling the first fan assembly 201 and the second fan assembly 202 to be in the second working position if T0 is greater than T. Thus, in the cooling mode, the first fan assembly 201 and the second fan assembly 202 are in the second working position. In the second working position, the rotation centerline of the first wind wheel 2011 and the rotation centerline of the second wind wheel 2021 are both inclined toward the direction close to the center of the housing 10, thereby facilitating the first wind wheel 2011 and the second wind wheel 2021 to drive the airflow from the air inlet d into the air duct a, and respectively drive the airflow in the air duct a to flow to their respective corresponding heat exchangers, which helps to increase the driving effect of the two fan assemblies on the airflow and increase the air volume.

[0134] According to some embodiments of the present invention, Figure 10 As shown, when the housing 10 includes the above-mentioned first air duct a1 and second air duct a2, if the instruction is to turn on the cooling mode, the step of controlling the first wind wheel 2011 and the second wind wheel 2021 to rotate forward specifically includes: obtaining the indoor ambient temperature T0 of the environment in which the air conditioner 1 is located. Specifically, the indoor ambient temperature can be obtained using a temperature sensor. It should be understood that the temperature sensor can be integrated on the air conditioner 1 or placed indoors, that is, separated from the air conditioner. If the temperature sensor is set separately from the air conditioner 1, the temperature sensor can communicate with the controller in the air conditioner 1 via wired communication or wireless communication.

[0135] The indoor ambient temperature T0 is compared with a preset value T; wherein the preset value T may be a value set when the air conditioner 1 leaves the factory, or a value set by the user according to actual needs.

[0136] If T0 is greater than T, the compressor is controlled to operate at the second target frequency and the first wind wheel 2011 and the second wind wheel 2021 are rotated, and the first fan assembly 201 is controlled to rotate so that the angle between the rotation center line of the first wind wheel 2011 and the plane where the second air inlet d2 is located is not less than 90° (for example, 90°), so as to avoid the first fan assembly 201 supplying air toward the second air inlet d2, affecting the cooling effect.

[0137] According to some embodiments of the present invention, a wind guide 107 is rotatably provided at the first sub-air outlet e1. If T0 is greater than T, the wind guide 107 is controlled to open the first sub-air outlet e1. Specifically, in this step, the wind guide 107 can be controlled to rotate in a direction away from the second air inlet d2 to supply air in a direction away from the second air inlet d2 (for example, Figure 4 The air is supplied obliquely upwards to improve the cooling effect.
