[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] like Figure 1 、 Figure 4-Figure 6 as well as Figure 9 As shown, the air conditioner 1 according to the embodiment of the present invention may include a housing 10 , a first heat exchanger 30 , a second heat exchanger 40 and an axial flow fan assembly 20 .

[0052] like Figure 2-Figure 3 as well as Figure 10 As shown, the housing 10 has an air duct a, an air inlet d provided on the housing 10, the air inlet d communicating with the air duct a, a first air outlet e provided on the housing 10, the first air outlet e communicating with the air duct a, and a second air outlet f provided on the housing 10, the second air outlet f communicating with the air duct a. In other words, the housing 10 is provided with the air inlet d, the first air outlet e, and the 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.

[0053] Specifically, the first heat exchanger 30 and the second heat exchanger 40 are both located in the air duct a, with the first heat exchanger 30 located between the air inlet d and the first air outlet e, and the second heat exchanger 40 located between the air inlet d and the second air outlet f. In other words, the first heat exchanger 30 is installed in the air duct a, and the second heat exchanger 40 is installed in the air duct a, with the first heat exchanger 30 located between the air inlet d and the first air outlet e, and the second heat exchanger 40 located between the air inlet d and the second air outlet f, thereby facilitating heat exchange between the airflow in the air duct a and the first heat exchanger 30 and the second heat exchanger 40.

[0054] Among them, 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 second heat exchanger 40 can be a condenser, or the first heat exchanger 30 can be a condenser, and the second heat exchanger 40 can be an evaporator.

[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, and the second heat exchanger 40 is a condenser. 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, and the second heat exchanger 40 is a condenser. In heating mode, the first heat exchanger 30 is a condenser, and the second heat exchanger 40 is an evaporator. Thus, on the one hand, the evaporator and condenser are both integrated into a single housing 10, making the air conditioner 1 an all-in-one air conditioner 1. Compared to a split-type air conditioner 1, when the user uses the air conditioner, there is no need to install the indoor and outdoor units on-site, saving labor costs and reducing costs. On the other hand, the evaporator and condenser are both located in the same air duct a, making the structure simpler and more compact. There is no need to set up separate air ducts a corresponding to the evaporator and condenser, respectively, which is beneficial to improving production efficiency and further reducing costs.

[0056] When the air conditioner 1 is in the off state, the axial flow fan assembly 20 is located in the air duct a. Figures 9-11 As shown, the axial flow fan assembly 20 is always located in the air duct a. Figure 2-Figure 4 As shown, the axial flow fan assembly 20 is in an open state, with a portion of the axial flow fan assembly 20 located outside the housing and another portion located in the air duct a.

[0057] Therefore, the axial fan assembly 20, the first heat exchanger 30 and the second heat exchanger 40 share the air duct a, and the evaporator and the condenser share the air duct a and the axial fan assembly 20, which makes the structure simpler and more compact, is conducive to improving production efficiency, reducing costs, and simplifying the structure of the air conditioner 1.

[0058] like Figure 5-Figure 8 as well as Figure 11 As shown, the first heat exchanger 30 and the second heat exchanger 40 are arranged opposite to each other in the first direction, the first air outlet e is located on the side of the first heat exchanger 30 away from the second heat exchanger 40, and the second air outlet f is located on the side of the second heat exchanger 40 away from the first heat exchanger 30. Thus, in the first direction, the first air outlet e, the first heat exchanger 30, the second heat exchanger 40, and the second air outlet f are arranged in sequence.

[0059] Further, in the first direction, the axial fan assembly 20 is located between the first heat exchanger 30 and the second heat exchanger 40, and the air inlet d is located between the first heat exchanger 30 and the second heat exchanger 40. For example, the first heat exchanger 30 and the second heat exchanger 40 can be arranged relative to each other in the horizontal direction, referring to Figure 2 and Figure 4 As shown, the first heat exchanger 30 and the second heat exchanger 40 are both arranged vertically, the first heat exchanger 30 is located in front of the second heat exchanger 40, a first air outlet e is provided on the front side wall of the shell 10, a second air outlet f is provided on the rear side wall of the shell 10, and an air inlet d is provided on the top wall or bottom wall of the shell 10.

[0060] The axial flow fan assembly 20 has a first operating mode and a second operating mode. In the first operating mode and the second operating mode, the axial flow fan assembly 20 drives the airflow in opposite directions. Specifically, in the cooling mode, the axial flow fan assembly 20 operates in the first operating mode, and in the dehumidification mode, the axial flow fan assembly 20 operates in the second operating mode.

[0061] Specifically, refer to Figure 5-Figure 6 as well as Figure 10 As shown, in the cooling mode, the axial flow fan assembly 20 operates in the first working mode. The axial flow fan assembly 20 drives the air flow from the air inlet d into the air duct a, and drives a part of the air flow into the air duct a to exchange heat with the first heat exchanger 30 and then be discharged from the first air outlet e, and drives the remaining air flow into the air duct a to exchange heat with the second heat exchanger 40 and then be discharged from the second air outlet f.

[0062] Reference Figure 7-Figure 8 as well as Figure 11As shown, in the dehumidification mode, the axial flow fan assembly 20 operates in the second working mode, and the axial flow fan assembly 20 drives a part of the air flow from the first air outlet e into the air duct a and exchanges heat with the first heat exchanger 30, and drives another part of the air flow from the second air outlet f into the air duct a and exchanges heat with the second heat exchanger 40, and further drives the air flow after heat exchange with the first heat exchanger 30 and the air flow after heat exchange with the second heat exchanger 40 to mix to form a mixed air flow and discharge from the air inlet d. Specifically, in the dehumidification mode, since the first heat exchanger 30 is an evaporator, a part of the air flow entering the air duct a flows through the first heat exchanger 30 and is cooled and dehumidified for the first time to produce condensed water to form a cold air flow, while the remaining air flow entering the air duct a flows to the second heat exchanger 40 and is heated to form a hot air flow. The cold air flow and the hot air flow mix to produce condensed water, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect. At the same time, the hot air flow can also play a certain heating role on the cold air flow, ensuring that the temperature of the discharged air flow is not too low, which is beneficial to achieving the purpose of dehumidification without cooling, and realizing the independence of dehumidification and refrigeration.

[0063] It can be understood that when the air conditioner 1 is a heating and cooling type air conditioner 1, in the heating mode, the axial fan assembly 20 operates in the first working mode, and the axial fan assembly 20 can drive the airflow from the air inlet d into the air duct a. A part of the airflow entering the air duct a is heat-exchanged with the first heat exchanger 30 to form a first heat-exchanged airflow and is discharged from the first air outlet e. The remaining airflow entering the air duct a is heat-exchanged with the second heat exchanger 40 to form a second heat-exchanged airflow and is discharged from the second air outlet f.

[0064] According to the air conditioner 1 of the embodiment of the present invention, by sharing the axial flow fan assembly 20 and the air duct a for the first heat exchanger 30 and the second heat exchanger 40, not only the structure is simpler and more compact, which is beneficial to improving production efficiency, reducing costs, and simplifying the structure of the air conditioner 1, but also the working mode of the axial flow fan assembly 20 can be switched to change the flow direction of the airflow, and the purpose of dehumidification can be achieved by using a mixture of cold and hot air, with a good dehumidification effect. The air conditioner 1 can independently realize the cooling function, and can also independently realize the dehumidification function, that is, dehumidification without cooling, which better meets the user's usage needs.

[0065] In some embodiments of the present invention, reference Figure 1 As shown, air conditioner 1 includes a switch member 50 movably mounted on housing 10 to open or close first air outlet e. Specifically, when air conditioner 1 is turned on, switch member 50 opens first air outlet e. Thus, by providing switch member 50, when air conditioner 1 is in use, switch member 50 opens air inlet d, thereby facilitating airflow between air duct a and the indoor environment. When air conditioner 1 is not in use, switch member 50 closes air inlet d, thereby preventing dust from entering.

[0066] For example, when the air conditioner 1 is a cooling-only type air conditioner 1, the switch 50 opens the first air outlet e when the air conditioner 1 is in cooling mode and dehumidification mode. For another example, when the air conditioner 1 is a cooling-heating type air conditioner 1, the switch 50 opens the first air outlet e when the air conditioner 1 is in cooling mode, dehumidification mode, and heating mode.

[0067] In some embodiments of the present invention, reference Figure 1 As shown, the switch member 50 is a wind deflector, which is rotatably arranged at the first air outlet e. Therefore, by configuring the switch member 50 as a wind deflector, it can not only open and close the first air outlet e, but also guide the air, which better meets the user's usage needs.

[0068] Of course, the present invention is not limited to this. In other embodiments, the switch member 50 can also be a switch door, which is movably provided on the housing 10 and is used to open or close the first air outlet e, which is simpler.

[0069] In some embodiments, the switch element 50 is an integrally molded component. For example, the switch element 50 is an integrally injection-molded component. This integral structure not only ensures the structural and performance stability of the switch element 50, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, significantly improving assembly efficiency and ensuring reliable connection of the switch element 50. Furthermore, the integral structure offers greater overall strength and stability, making assembly easier and extending its lifespan.

[0070] In other embodiments, in order to ensure the structural strength of the switch member 50 , the switch member 50 may also be a metal member.

[0071] According to some embodiments of the present invention, referring to Figure 2-Figure 3 As shown, the air conditioner 1 includes an opening and closing member 60 movably mounted on the housing 10 to open or close the air inlet d. When the air conditioner 1 is turned on, the opening and closing member 60 opens the air inlet d, and when the air conditioner 1 is turned off, the opening and closing member 60 closes the air inlet d. For example, when the air conditioner 1 is in dehumidification mode or cooling mode, the opening and closing member 60 opens the air inlet d. Thus, by providing the opening and closing member 60, when the air conditioner 1 is in use, the opening and closing member 60 opens the air inlet d, thereby facilitating airflow between the air duct a and the indoor environment. When the air conditioner 1 is not in use, the opening and closing member 60 closes the air inlet d, thereby preventing dust from entering.

[0072] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, the air inlet d is located on a side wall of the housing 10 along a second direction, and the opening and closing member 60 is movably provided on the housing 10 along the second direction to open or close the air intake, wherein the second direction is perpendicular to the first direction.

[0073] Specifically, refer to Figure 2-Figure 3 As shown, the opening and closing member 60 includes: a shielding plate 601 and a connecting member 602. One end of the connecting member 602 is slidably arranged in the housing 10, and the other end of the connecting member 602 is connected to the shielding plate 601. The shielding plate 601 is used to open or close the air inlet d. Specifically, for example, referring to Figure 2 As shown, the air inlet d is provided on the bottom wall of the housing 10. The upper end of the connector 602 is connected to the interior of the housing 10 and is slidable in the vertical direction relative to the housing 10. The lower end of the connector 602 is connected to the outer peripheral wall of the shielding plate 601. When the connector 602 moves up and down relative to the housing 10, the movement of the connector 602 causes the shielding plate 601 to move up and down. The up and down movement of the shielding plate 601 thereby opens or closes the air inlet d. Thus, when the air conditioner 1 is in the on state, the opening and closing member 60 can move downward, leaving space for the air inlet d, thereby opening the air inlet d; when the air conditioner 1 is turned off, the opening and closing member 60 can move upward again, returning to its initial state, and closing the air inlet d. This reduces the height of the entire unit, thereby reducing the space occupied. At the same time, closing the unit when not in use can prevent dust from entering, resulting in a simple structure.

[0074] According to some embodiments of the present invention, the axial fan assembly 20 is installed on the opening and closing member 60. For example, the axial fan assembly 20 is installed at the end of the above-mentioned connecting member 602 away from the baffle 601, so that when the opening and closing member 60 moves in the second direction relative to the shell 10, the axial fan assembly 20 moves accordingly, so that when the opening and closing member 60 closes the air inlet d, the axial fan assembly 20 can be located in the shell 10, and when the opening and closing member 60 opens the air inlet d, the axial fan assembly 20 is located at the air inlet d, wherein the rotation centerline of the axial fan assembly 20 extends along the second direction.

[0075] Specifically, if Figure 6 and Figure 8As shown, when the opening and closing member 60 opens the air inlet d, the axial flow fan assembly 20 is positioned at the air inlet d, thereby defining an airflow chamber m between the axial flow fan assembly 20, the first heat exchanger 30, and the second heat exchanger 40. In cooling mode, the axial flow fan assembly 20 rotates forward, thereby driving the airflow from the air inlet d into the airflow chamber m, while at the same time branching off at the airflow chamber m, with a portion of the airflow flowing to the first heat exchanger 30, exchanging heat with the first heat exchanger 30, and then being discharged from the first air outlet e, while the other portion of the airflow flows to the second heat exchanger 40, exchanging heat with the second heat exchanger 40, and then being discharged from the second air outlet f; in dehumidification mode, the axial flow fan assembly 20 reverses, thereby driving the airflow from the first air outlet e and the second air outlet f into the air duct a, respectively, and the airflow entering the air duct a from the first air outlet e is separated from the airflow from the first air outlet e. After heat exchange in the heat exchanger 30, it flows to the air flow chamber m. The air flow entering the air duct a from the second air outlet f exchanges heat with the second heat exchanger 40 and flows to the air flow chamber m. Since the first heat exchanger 30 is an evaporator, a part of the air flow entering the air duct a flows through the first heat exchanger 30, is cooled and dehumidified for the first time to produce condensed water, and then forms a cold air flow which further flows to the air flow chamber m. The remaining air flow entering the air duct a flows to the second heat exchanger 40, is heated, and forms a hot air flow. The cold air flow and the hot air flow can be mixed in the air flow chamber m to produce condensed water, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect.

[0076] Therefore, by arranging the axial fan assembly 20 on the opening and closing member 60, when the opening and closing member 60 opens the air inlet d, an air flow cavity m is defined between the axial fan assembly 20, the first heat exchanger 30 and the second heat exchanger 40. This is conducive to the full mixing of the cold air flow and the hot air flow in the dehumidification mode, thereby achieving the purpose of dehumidification.

[0077] Specifically, if Figure 2-Figure 3 As shown, when the opening and closing member 60 opens the air inlet d, one axial end of the axial flow fan assembly 20 is located outside the housing 10, and the other axial end of the axial flow fan assembly 20 is located in the air duct a.

[0078] In some embodiments of the present invention, in order to simplify the structure and reduce the cost, the axial flow fan assembly 20 is an axial flow fan.

[0079] In some embodiments, the opening and closing member 60 is an integrally molded part. For example, the opening and closing member 60 is an integrally injection-molded part. This integral structure not only ensures the structural and performance stability of the opening and closing member 60, but also facilitates molding and simplifies manufacturing. It also eliminates redundant assembly parts and connection steps, significantly improving assembly efficiency and ensuring reliable connection of the opening and closing member 60. Furthermore, the integral structure offers greater overall strength and stability, making assembly easier and extending its lifespan.

[0080] In other embodiments, in order to ensure the structural strength of the opening and closing member 60, the opening and closing member 60 may also be a metal member.

[0081] Optionally, a guide groove is provided on the housing 1010, and the connecting member 602 can be slidably provided in the guide groove. Therefore, by providing the guide groove, it is beneficial to guide the movement of the opening and closing member 60, thereby improving the reliability of the opening and closing member 60.

[0082] In some embodiments of the present invention, Figure 2 As shown, a hanging component 80 is provided on the outer surface of the housing 10, whereby the air conditioner 11 can be hung up using the hanging component 80 for easy installation.

[0083] Specifically, the suspension component 80 is provided on a side of the housing 10 opposite to the air inlet d. Thus, the structural layout of the air conditioner 11 can be reasonably optimized.

[0084] In some embodiments of the present invention, reference Figures 9-11 As shown, the axial flow fan assembly 20 is located in the housing 10, and the axial flow fan assembly 20 includes a first axial flow fan 201 and a second axial flow fan 202 that are opposite to each other and spaced apart in a first direction. The first axial flow fan 201 drives the airflow to exchange heat with the first heat exchanger 30 and then is discharged from the first air outlet e, and the second axial flow fan 202 drives the airflow to exchange heat with the second heat exchanger 40 and then is discharged from the second air outlet f. Specifically, in the cooling mode, the first axial fan 201 rotates forward to drive a part of the air flow in the air duct a to exchange heat with the first heat exchanger 30 and then be discharged through the first air outlet e, and the second axial fan 202 rotates forward to drive the remaining air flow in the air duct a to exchange heat with the second heat exchanger 40 and then be discharged through the second air outlet f; in the dehumidification mode, the first axial fan 201 reverses to drive a part of the air flow into the air duct a from the first air outlet e and exchange heat with the first heat exchanger 30, and the second axial fan 202 reverses to drive another part of the air flow into the air duct a from the second air outlet f and exchange heat with the second heat exchanger 40. The first axial fan 201 and the second axial fan 202 further drive the air flow after heat exchange with the first heat exchanger 30 and the air flow after heat exchange with the second heat exchanger 40 to mix to form a mixed air flow and discharge it from the air inlet d.

[0085] In some embodiments of the present invention, reference Figures 9-11As shown, the rotation centerlines of the first axial fan 201 and the second axial fan 202 are both tilted toward the center of the housing 10, near the air inlet d. This allows the first and second axial fans 201, 202 to drive airflow from the air inlet d into the air duct a and, in turn, to drive the airflow within the air duct a toward their respective heat exchangers in the cooling mode. This helps increase the airflow driving effect of the axial fan assembly 20 and improves air volume. Furthermore, in the dehumidification mode, the cold and hot air flows mix and are then discharged from the air inlet d, increasing air volume and further enhancing the dehumidification effect.

[0086] In some embodiments of the present invention, reference Figure 9 As shown, the angle α between the rotation centerline of the first axial flow fan 201 and the rotation centerline of the second axial flow fan 202 ranges from 200° to 250°. For example, α 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 axial flow fan 201 and the second axial flow fan 202 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, thereby increasing the driving effect of the axial flow fan assembly 20 on the airflow and improving the air volume. And in the dehumidification mode, the cold airflow and the hot airflow are mixed and discharged from the air inlet d to increase the air volume.

[0087] In some embodiments of the present invention, Figure 9 As shown, a rotatable air guide grille 90 is provided at the air inlet d, with the rotation centerline of the air guide grille 90 being perpendicular to the air inlet d. Thus, in the dehumidification mode, the rotation of the air guide grille 90 not only serves to guide the air, but also further disturbs the mixed airflow as it passes through the air guide grille 90, thereby further mixing the airflow and improving the dehumidification effect.

[0088] In some embodiments of the present invention, the air guide grille 90 includes a circular outer ring and an inner ring. The outer ring surrounds the inner ring, and a plurality of first sub-grill bars are disposed between the inner circumferential wall of the outer ring and the outer circumferential wall of the inner ring. The plurality of first sub-grill bars are spaced apart along the circumference of the outer ring. The inner circumferential wall of the inner ring is provided with a plurality of second sub-grill bars, and the plurality of second sub-grill bars are connected to the inner ring at both ends. This results in a simple structure.

[0089] Furthermore, in the radially outward direction, the first sub-grid bars are inclined clockwise or counterclockwise, thereby improving the turbulence effect on the airflow.

[0090] According to some optional embodiments of the present invention, the air guide grille 90 is a single-piece component. For example, the air guide grille 90 is a one-piece injection-molded component. This one-piece structure not only ensures the structural and performance stability of the air guide grille 90, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, significantly improving the assembly efficiency of the air guide grille 90 and ensuring the reliability of the air guide grille 90 connection. Furthermore, the one-piece structure offers greater overall strength and stability, making assembly easier and extending its lifespan.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Alternatively, as Figure 3 As shown, an air outlet grille 101 is provided at the second air outlet f, thereby improving safety and preventing hands and the like from extending into the air duct a through the second air outlet f.

[0099] Specifically, the air outlet grille 101 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.

[0100] 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.

[0101] Optionally, the air outlet grille 101 is an integrally formed part. Thus, the integral structure not only ensures the structural and performance stability of the air outlet grille 101, 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 101 and ensuring the reliability of the connection of the air outlet grille 101. Furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0102] According to some further embodiments of the present invention, the air outlet grille 101 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 101 .

[0103] In some embodiments of the present invention, at least one of the first heat exchanger 30 and the second heat exchanger 40 is formed in an arc shape extending along the circumference of the housing 10. That is, the first heat exchanger 30 is formed in an arc shape extending along the circumference of the housing 10, the second heat exchanger 40 is formed in an arc 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 an arc 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.

[0104] According to some embodiments of the present invention, 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. Thus, 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.

[0105] 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.

[0106] 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.

[0107] The following describes a control method of the air conditioner 1 according to an embodiment of the present invention. The air conditioner 1 includes a dehumidification mode and a cooling mode.

[0108] Reference Figure 12 and Figure 14 As shown, the control method of the air conditioner 1 according to the embodiment of the present invention includes the following steps:

[0109] Receive user instructions;

[0110] 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.

[0111] If the instruction is to start the cooling mode, the axial flow fan assembly 20 is controlled to rotate forward and operate in the first working mode;

[0112] If the instruction is to start the dehumidification mode, the axial flow fan assembly 20 is controlled to reverse and operate in the second working mode.

[0113] According to the air conditioner 1 of the embodiment of the present invention, when the dehumidification mode is turned on, the axial flow fan assembly 20 is controlled to operate in the second operating mode, thereby achieving the purpose of dehumidification, which is conducive to improving the dehumidification effect.

[0114] According to some embodiments of the present invention, referring to Figure 12 and Figure 14 As shown, if the instruction is to turn on the dehumidification mode, the steps of controlling the axial flow fan assembly 20 to reverse and operate in the second working mode specifically include:

[0115] The indoor humidity Φ1 of the environment where the air conditioner 1 is located is obtained.

[0116] 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.

[0117] 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.

[0118] 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 axial fan assembly 20 can be controlled to operate in the second operating mode. The axial fan assembly 20 drives a portion of the airflow from the first air outlet e into the air duct a and exchanges heat with the first heat exchanger 30, and drives another portion of the airflow from the second air outlet f into the air duct a and exchanges heat with the second heat exchanger 40. The airflow after heat exchange with the first heat exchanger 30 and the airflow after heat exchange with the second heat exchanger 40 are further driven to mix to form a mixed airflow, which is discharged from the air inlet d. Specifically, in the dehumidification mode, since the first heat exchanger 30 is an evaporator, a portion of the airflow entering the air duct a flows through the first heat exchanger 30, is first cooled and dehumidified, and condensed water is generated to form a cold airflow. The cold airflow further flows to the air inlet d, while the remaining airflow entering the air duct a flows to the second heat exchanger 40, is heated, and forms a hot airflow. The cold airflow and the hot airflow mix to produce condensed water, thereby achieving the purpose of dehumidification and improving the dehumidification effect.

[0119] According to the air conditioner 1 of an embodiment of the present invention, by comparing the obtained indoor ambient humidity Φ1 of the environment where the air conditioner 1 is located with the set value Φ, when Φ1 is greater than Φ, the axial fan assembly 20 operates in the second working mode and controls the compressor to operate at the first target frequency, thereby achieving the purpose of dehumidification, which is beneficial to improving the dehumidification effect.

[0120] Optionally, the first target frequency may be the rated frequency of the compressor, thereby further improving the dehumidification effect.

[0121] In some embodiments of the present invention, when the air conditioner 1 includes the above-mentioned opening and closing member 60, if Φ1 is greater than Φ, the opening and closing member 60 is controlled to open the air inlet d, thereby facilitating the circulation of airflow.

[0122] In some embodiments of the present invention, after the compressor is controlled to operate at the first target frequency and the axial fan assembly 20 is controlled to operate in the second operating mode, the air inlet temperature T3 of the housing 10, 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 of the housing 10, 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 5 、 Figure 7 and Figure 9As shown, a first temperature sensor 102 is provided at the first air outlet e and / or at the second air outlet f, 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 the first heat exchanger 30. The first temperature sensor 102 is used to obtain the air inlet temperature of the shell 10 in the dehumidification mode, the second temperature sensor 103 is used to obtain the air outlet temperature T1 of the evaporator in the dehumidification mode, and the third temperature sensor 104 is used to obtain the air outlet temperature T2 of the condenser in the dehumidification mode.

[0123] The cold air volume q1 of the evaporator and the hot air volume q2 of the condenser are generated according to the rotational speed of the axial fan assembly 20; the actual cooling capacity Q1 of the evaporator is generated according to the air inlet temperature T3 of the shell 10, 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 T3 of the shell 10, 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.

[0124] 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 axial fan assembly 20 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.

[0125] In some specific examples, if T1 is greater than Td, the speed of the axial fan assembly 20 is controlled to be reduced to the minimum speed and / or the frequency of the compressor is controlled to be increased to the maximum frequency. This can increase the difference between the outlet air temperature of the evaporator and the outlet air temperature of the condenser, further improving the dehumidification effect.

[0126] 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.

[0127] According to some embodiments of the present invention, an air conditioner 1 includes the aforementioned air guide grille 90. A control method for air conditioner 1 includes: if Φ1 is greater than Φ, indicating that the indoor humidity is high and dehumidification is required, while controlling the compressor to operate at a first target frequency P1 and the axial flow fan assembly 20 to operate in a second operating mode, controlling the air guide grille 90 to rotate at a first speed m1, wherein the speed of the first axial flow fan 201 is n1 and the speed of the second axial flow fan is n2. This facilitates utilizing the turbulent effect of the air guide grille 90 to further achieve mixing of the cold and hot air flows, thereby achieving the purpose of dehumidification.

[0128] According to some embodiments of the present invention, after controlling the air guide grille 90 to rotate at the first speed m1, controlling the compressor to operate at the first target frequency, and controlling the axial flow fan assembly 20 to operate in the second working mode,

[0129] Detect the air inlet temperature T3 of the housing 10, detect the air outlet temperature T1 of the evaporator, and detect the air outlet temperature T2 of the condenser. Specifically, the air inlet temperature T3 of the housing 10, 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 5 、 Figure 7 and Figure 9 As shown, a first temperature sensor 102 is provided at the first air outlet e and / or at the second air outlet f, 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 the first heat exchanger 30. The first temperature sensor 102 is used to obtain the air inlet temperature of the shell 10 in the dehumidification mode, the second temperature sensor 103 is used to obtain the air outlet temperature T1 of the evaporator in the dehumidification mode, and the third temperature sensor 104 is used to obtain the air outlet temperature T2 of the condenser in the dehumidification mode.

[0130] The cold air volume q1 of the evaporator is generated according to the rotational speed n1 of the first axial fan 201, the hot air volume q2 of the condenser is generated according to the rotational speed n2 of the second axial fan 202, the actual cooling capacity Q1 of the evaporator is generated according to the air inlet temperature T3 of the shell 10, 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 T3 of the shell 10, the air outlet temperature T2 of the condenser and the hot air volume q2 of the condenser; the relative humidity Φ3 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.

[0131] Detect the actual outlet humidity Φ3' at the air inlet d, and compare the relative humidity Φ3 with the actual outlet humidity Φ3'.

[0132] If Φ3' is greater than Φ3, the speed of the air guide grille 90 is increased; and / or the speed of the first axial fan 201 is decreased; and / or the speed of the second axial fan 202 is decreased; and / or the frequency of the compressor is increased. In other words, if Φ3' is greater than Φ3, at least one of the speeds of the air guide grille 90, the speeds of the first axial fan 201, the speeds of the second axial fan 202, or the frequency of the compressor can be adjusted. For example, one, two, three, or all of the speeds of the air guide grille 90, the speeds of the first axial fan 201, the speeds of the second axial fan 202, or the frequency of the compressor can be adjusted, thereby further improving the dehumidification effect.

[0133] In some embodiments of the present invention, Figure 14 As shown, after detecting that the actual air outlet humidity Φ3' is greater than Φ3, and adjusting at least one of the rotation speed of the air guide grille 90, the rotation speed of the first axial fan 201, the rotation speed of the second axial fan 202, and the frequency of the compressor, it returns to the steps of repeatedly detecting the air inlet temperature T3 of the detection shell 10, detecting the air outlet temperature T1 of the evaporator, and detecting the air outlet temperature T2 of the condenser and executes them in sequence. If it is detected again that Φ3' is greater than Φ3, the rotation speed of the air guide grille 90 is further controlled to increase; and / or the rotation speed of the first axial fan 201 is controlled to decrease; and / or the rotation speed of the second axial fan 202 is controlled to decrease; and / or the frequency of the compressor is controlled to increase, until it is detected that Φ3' is less than or equal to Φ3, and the dehumidification mode is exited.

[0134] It is understood that during the repeated execution, if Φ3' is greater than Φ3, different parameters can be adjusted each time. For example, after the first detection that Φ3' is greater than Φ3, the speed of the air guide grille 90 is increased, and the process returns to the steps of repeatedly detecting the air inlet temperature T3 of the detection housing 10, detecting the air outlet temperature T1 of the evaporator, and detecting the air outlet temperature T2 of the condenser, and the steps are performed in sequence. If Φ3' is again detected to be greater than Φ3, the speed of the first axial flow fan 201 is controlled to decrease, the speed of the second axial flow fan 202 is controlled to decrease, and the frequency of the compressor is controlled to increase.

[0135] According to some embodiments of the present invention, Figure 13 As shown, if the instruction is to turn on the cooling mode, the steps of controlling the axial flow fan assembly 20 to rotate forward and operate in the first working mode specifically include:

[0136] The indoor ambient temperature T0 of the environment in which the air conditioner 1 is located is obtained. Specifically, the indoor ambient temperature can be obtained using a temperature sensor. It should be understood that the temperature sensor can be integrated into the air conditioner 1 or placed indoors, that is, separated from the air conditioner. If the temperature sensor is provided separately from the air conditioner 1, the temperature sensor can communicate with the controller in the air conditioner 1 via a wired connection or wirelessly. 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.

[0137] 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.

[0138] If T0 is greater than T, the compressor is controlled to operate at the second target frequency, and the axial fan assembly 20 is controlled to operate in the first operating mode. Consequently, the axial fan assembly 20 drives air from the air inlet d into the air duct a. Further driven by the axial fan assembly 20, a portion of the airflow in duct a exchanges heat with the first heat exchanger 30 before being discharged through the first air outlet e. The remaining airflow exchanges heat with the second heat exchanger 40 before being discharged through the second air outlet f, thereby achieving cooling.

[0139] 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.

[0140] Optionally, the second target frequency is a rated frequency, thereby improving the cooling effect.

[0141] In some embodiments of the present invention, when the air conditioner 1 includes the above-mentioned opening and closing member 60, if T0 is greater than T, the opening and closing member 60 is controlled to open the air inlet d, thereby facilitating the circulation of air.
