Detailed Embodiments

[0047] To make the purpose and implementation manner of this application clearer, the following will clearly and completely describe the exemplary implementation manner of this application in combination with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0048] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0049] The terms "first" and "second" are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "plural" is two or more.

[0050] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0051] In the present application, the air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0052] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0053] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0054] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0055] The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0056] The air conditioner of the present application has a ceiling-mounted structure and is mainly applied in places such as kitchens and bathrooms, but can also be applied in other places.

[0057] Refer to Figure 1 and Figure 2 , the air conditioner includes a housing assembly; the housing assembly can form the overall appearance of the air conditioner.

[0058] The housing assembly includes a panel assembly 10 and a housing 20. The panel assembly 10 is connected to the bottom end of the housing 20. In the application scenario, usually the bottom of the panel assembly 10 is exposed outside the ceiling, and the housing 10 is installed inside the ceiling.

[0059] Refer to Figure 3 and Figure 4 , the panel assembly 10 includes a bottom plate 11, and an air inlet frame 12 is connected to the bottom plate 11. The middle of the air inlet frame 12 is penetrated to form an air inlet part 101, and the air inlet part 101 is used for allowing indoor air to flow in, that is, the indoor air can enter the housing assembly from the air inlet part.

[0060] An air outlet frame 13 is connected to the bottom plate 11. The middle of the air outlet frame 13 is penetrated to form an air supply part 102, and the indoor air is sent into the room by the air supply part 102 after being processed in the air conditioner.

[0061] As an example, the air inlet frame 12, the air outlet frame 13 and the bottom plate 11 are integrally formed, and the air inlet frame 12 and the air outlet frame 13 are respectively formed by extending upward from the bottom plate 11.

[0062] The bottom end of the air inlet part 101 is an air inlet, and the bottom end of the air supply part 102 is an air supply outlet 112.

[0063] Alternatively, the air inlet frame 12, the air outlet frame 12, and the bottom plate 11 are of a split connection structure, and the bottom plate 11 is provided with an air inlet corresponding to the air inlet part 101 of the air supply part and an air supply outlet corresponding to the air supply part 102.

[0064] The panel assembly 10 may include an air inlet grille 14, and the air inlet grille 14 is connected at the air inlet and can play a certain guiding and filtering role for the incoming air.

[0065] The panel assembly 10 may include a filtering unit 15, which is arranged inside the air inlet grille 14 and is used for filtering and purifying the air.

[0066] Taking the example where the air supply outlet 112 is on the left and the air inlet is on the right, the left and right inner sides of the air outlet frame 13 gradually extend to the left from top to bottom, so that the air supply part 102 supplies air to the lower left.

[0067] For convenience of description, the right inner side of the air outlet frame 13 is called the first air supply guiding surface 13a, and the left inner side of the air outlet frame 13 is called the second air supply guiding surface 13b. That is, among the sides enclosing the air supply part 102, the side close to the air inlet part 101 is the first air supply guiding surface 13a, and the side far from the air inlet part 101 is the second air supply guiding surface 13b.

[0068] The panel assembly 10 includes a wind deflector 16 that can open or close the air supply outlet 112, and the wind deflector 16 is rotatably arranged at the air supply outlet 112.

[0069] The rotating shaft of the wind deflector 16 is close to the right side of the wind deflector 16. When the wind deflector 16 opens the air supply outlet 112, the left end of the wind deflector 16 rotates downward, and the right end of the wind deflector 16 rotates upward into the air supply part 102; when the wind deflector 16 closes the air supply outlet 112, the left end of the wind deflector 16 rotates upward, and the right end of the wind deflector 16 rotates downward.

[0070] When the wind deflector 16 is in the open state, since there is a gap between the wind deflector 16 and the first air supply guiding surface 13a, therefore, air flows out on both the left and right sides of the wind deflector 16, and the temperature is relatively uniform, which can avoid condensation on the wind deflector 16.

[0071] In some embodiments, the right end of the wind deflector 16 is upturned, so that even when the wind deflector 16 is opened at a small angle, a gap can be formed between the right end of the wind deflector 16 and the first air supply guiding surface 13a.

[0072] The bottom surface of the wind deflector 16 is covered with a heat insulation layer, which can avoid condensation on the wind deflector 16.

[0073] The panel assembly 10 may include a plurality of swing blades 17, and the swing blades 17 are connected to the left end of the air supply part 102. Taking the length direction of the air supply part 102 as the front-back direction as an example for description. The plurality of swing blades 17 are arranged in the front-back direction in the air supply part 102 and are located inside the wind deflector 16. The swinging of the swing blades 17 can adjust the air supply range in the front-back direction.

[0074] Refer to Figure 2 and Figure 5 , the housing 20 may include a cuboid shape with an open lower end, and the lower end of the housing 20 is correspondingly connected to the panel assembly 10.

[0075] Inside the housing 20, there is a middle partition 21, which is connected to the left side wall of the air inlet frame 12. For the convenience of description, in the following text, the left side wall of the air inlet frame 12 is referred to as the first extension wall 121, and the middle partition 21 abuts against the first extension wall 121.

[0076] The middle partition 21 divides the space inside the housing 20 into an air inlet chamber 201 and an air outlet chamber 202. The air inlet chamber 201 is located on the right side and is connected to the air inlet part 101; the air outlet chamber 202 is located on the left side and is connected to the air supply part 102.

[0077] The air conditioner may include a fan 30, which is arranged in the air inlet chamber 201 and is used to blow air towards the air outlet chamber 202.

[0078] The fan 30 is connected to the top wall of the housing 20 and includes a fan 31 and a motor 32. The fan 31 can adopt a centrifugal fan, and the motor 32 is connected to one side of the fan 31 and is used to drive the fan 31 to rotate.

[0079] The fan 31 includes a volute 311 and an impeller. The volute 311 covers the impeller. Air suction ports are arranged on the front and rear sides of the volute 311, and an air discharge port is arranged at the left end of the volute 311. The air discharge end of the volute 311 penetrates through the middle partition 21.

[0080] Under the forced action of the fan 31, indoor air enters the air inlet chamber 201 from the air supply part 102, passes through the fan 31, flows into the air outlet chamber 202, and finally circulates back to the room from the air supply part 102.

[0081] In some embodiments, a sound insulation cotton 80 is connected to the middle partition 21. The sound insulation cotton 80 is located on the side of the air inlet chamber 201 and below the air discharge end of the volute 311, which can reduce the noise at this position.

[0082] The air conditioner further includes a heat exchanger 40, which is arranged in the air outlet chamber 202 and is located between the air discharge port of the fan 31 and the air supply part 102. The heat exchanger 40 is used to absorb heat from the air flowing into the air outlet chamber 202 or transfer heat to the air.

[0083] In some embodiments, the heat exchanger 40 is inclined, which can increase the size of the heat exchanger 40, thereby increasing the heat exchange area and improving the heat exchange efficiency.

[0084] Specifically, from top to bottom, the heat exchanger 40 is inclined towards the air inlet chamber 201 side, that is, the top end of the heat exchanger 40 is close to the left wall of the air outlet chamber 202, and the bottom end of the heat exchanger 40 is close to the right wall of the air outlet chamber 202.

[0085] In the front-rear direction, the heat exchanger 40 is close to the rear side of the air outlet chamber 202, and accessories such as pipelines and drainage pumps are close to the front side of the air outlet chamber 202.

[0086] According to an embodiment of the present application, the heat exchanger 40 may be a finned heat exchanger, which includes a refrigerant pipe having an "S" shape from top to bottom, and fins sleeved on the refrigerant pipe. End plates 41 are provided at the left and right ends of the heat exchanger 40 for fixing the fins.

[0087] An outdoor connection pipe is provided at one lateral end of the heat exchanger 40. The outdoor connection pipe is connected to the refrigerant pipe for connecting the heat exchanger 40 to the heat exchanger of the outdoor unit.

[0088] Exemplarily, the outdoor connection pipe is provided at the front side of the heat exchanger 40. That is to say, there is a space between the front side of the heat exchanger 40 and the front wall of the housing 20, and this space is used to accommodate the outdoor connection pipe and the like.

[0089] Refer to Figure 6 and Figure 7 The air conditioner further includes a water receiving tray 50. The water receiving tray 50 is arranged below the heat exchanger 40 for collecting the condensed water on the heat exchanger 40. The water receiving tray 50 can be connected to a drain pipe externally connected to the housing 20 and discharge the condensed water to the outside of the housing 20.

[0090] The water receiving tray 50 can be connected to the housing 20. An extending portion 51 extending outward is provided on the outer side wall of the water receiving tray 50, and the bottom of the housing 20 has an inward flanging. The extending portion 51 and the flanging are fixedly connected by screws.

[0091] According to an embodiment of the present application, the water receiving tray 50 includes a diversion area 52 and a collection area 53. The diversion area 52 and the collection area 53 are arranged front and back. The diversion area 52 supports the bottom end of the heat exchanger 40 and is mainly used for collecting condensed dew and diverting the condensed dew to the collection area 53; above the collection area 53 is a accommodation space for pipelines such as the outdoor connection pipe, and a drainage pump or the like can be provided corresponding to the upper part of the collection area 53.

[0092] The water receiving tray 50 may further include an auxiliary collection area 54. The auxiliary collection area 54 is connected to the air outlet side (left side) of the collection area 53. Viewed from top to bottom, the water receiving tray 50 is in an "L" shape. The auxiliary collection area 54 is used for collecting the condensed dew on the front side of the end plate 41 and on the exposed refrigerant pipe.

[0093] Through the design of the height difference, the condensed dew in the diversion area 52 and the auxiliary collection area 54 will flow towards the collection area 54, and then the condensed dew in the collection area 54 is discharged through natural drainage or a drainage pump.

[0094] The bottom surface height of the auxiliary collection area 54 is higher than the height of the collection area 54. In this way, a space is formed below the auxiliary collection area 54, and a driving device such as a wind deflector 16 and a swing blade 17 can be arranged in the space.

[0095] In the related art, the bottom end of the water receiving tray 50 usually does not extend beyond the housing 20. That is to say, the water receiving tray 50 is completely located inside the housing 20.

[0096] In an embodiment of the present application, there is also a space between the air inlet frame 12 and the air outlet frame 13. For convenience of description, in combination with Figure 4 ... This part of the space is called the concave cavity 18. That is, a concave cavity 18 located between the air inlet frame 12 and the air outlet frame 13 is provided on the panel assembly 10.

[0097] The water receiving tray 50 is exactly located above the concave cavity 18. In the present application, the bottom wall of the water receiving tray 50 protrudes into the concave cavity 18. At this time, since the bottom wall of the water receiving tray 50 protrudes downward, the bottom end of the heat exchanger 40 can extend downward following the bottom wall of the water receiving tray 50, thereby increasing the size of the heat exchanger 40, increasing the heat exchange area of the heat exchanger 40, and improving the heat exchange efficiency.

[0098] The present application utilizes the concave cavity 18 on the panel assembly 10 to make the size of the heat exchanger 40 larger without increasing the volume of the entire air conditioner. Therefore, on the premise of ensuring that the volume of the air conditioner remains unchanged, the present application increases the heat exchange area of the heat exchanger 40 and improves the heat exchange effect.

[0099] According to an embodiment of the present application, the diversion area 52 includes a support section 521. From top to bottom, the support section 521 is inclined towards the air supply part 102 and is used to support the heat exchanger 40.

[0100] The support section 521 can be located at the inner corner of the right side wall and the bottom wall of the water receiving tray 50, which can make the size of the heat exchanger 40 in the inclined direction as large as possible.

[0101] The inclined design of the support section 521 can, on the one hand, support the heat exchanger 40, and on the other hand, guide the condensed water at the bottom end of the heat exchanger 40 to flow downward along the support section 521.

[0102] In some embodiments, a convex portion 5211 is provided on the support section 521, and the bottom end of the heat exchanger 40 abuts against the convex portion 5211.

[0103] The width of the convex portion 5211 can be smaller than the thickness of the heat exchanger 40, so that a part of the bottom end of the heat exchanger 40 is supported by the convex portion 5211, reducing the blockage of the support section 521 to the bottom end of the heat exchanger 40 and increasing the heat exchange area that the bottom end of the heat exchanger 40 can act on.

[0104] According to an embodiment of the present application, the diversion area 52 further includes a diversion section 522, and the diversion section 522 is connected to the support section 521. In the lateral direction (from right to left) from the air inlet part 101 to the air supply part 102, the height of the diversion section 522 gradually increases. In this way, the position at the connection of the diversion section 522 and the support section 521 is lower.

[0105] Reference Figure 8 In the prior art, there is no diversion section 522 in the water receiving tray 50, and the side wall M of the water receiving tray 50 near the air outlet side is vertical. Then, the air at the bottom of the air outlet side of the heat exchanger 40 will be blocked by the side wall M when flowing in the water receiving tray 50 and flow upward, forming an impact with the air flow blown out from the middle of the heat exchanger 40, resulting in air volume loss.

[0106] In the application, the height of the diversion section 522 gradually increases along the air flow direction, guiding the air flow, so that the air flow at the lower part of the air outlet side of the heat exchanger 40 can smoothly flow to the air supply part 102, avoiding air volume loss.

[0107] In addition, the gradual change in the height of the diversion section 522 is also beneficial to the flow of condensate to the lower part, and also plays a guiding role in the condensate.

[0108] In some embodiments, the diversion section 522 is arc-shaped. After the air flow passes through the heat exchanger 40, the air flow at the bottom needs to flow out from the surface of the water receiving tray 50. The arc-shaped design of the diversion section 522 enables the air flow to smoothly flow out, increasing the air flow area and eliminating vortices and noise.

[0109] In some embodiments, the curvature C of the diversion section 522 satisfies: C≥0.002. For example, the curvature C is 0.04, 0.006, 0.008. If the curvature C of the diversion section 522 is too small, for example Figure 9 midline X, the diversion section 522 is relatively high. On the one hand, after the air flow passes through the heat exchanger 40, it is blocked by the diversion section 522, and less air flow is blown out. The air flow passing through the bottom of the heat exchanger is relatively small, which will reduce the heat exchange performance of the heat exchanger. On the other hand, it will greatly reduce the water capacity of the water receiving tray 50.

[0110] The curvature C of the diversion section 522 satisfies: C≤0.014. For example, the curvature C is 0.006, 0.01, 0.012. If the curvature C of the diversion section 500 is too large, for example Figure 9 midline Y, in the second half of the line Y of the air flow, the upward flow angle becomes steeper, forming an impact with the air flowing out from the middle of the heat exchanger 40, resulting in air volume loss.

[0111] According to the embodiments of the present application, the water receiving tray 50 further includes an air outlet transition section 55. The air outlet transition section 55 is connected to the air outlet end of the diversion section 522, and the air outlet transition section 55 is also the air outlet end of the water receiving tray 50.

[0112] The air outlet transition section 55 is connected to the top of the air outlet frame 13. Specifically, the side wall of the air outlet frame 13 close to the air inlet part 101 is defined as the second extension wall 131, and the air outlet transition section 55 can abut against the top of the second extension wall 131.

[0113] The inner wall surface of the air outlet transition section 55 is connected between the diversion section 522 and the second extension wall 131 to form the inner wall of the air duct. The inner wall surface of the air outlet transition section 55 is arc-shaped, enabling the air flow to smoothly flow from the diversion section 522 to the first air supply guiding surface 131a of the second extension wall 131, reducing the air flow noise.

[0114] In some embodiments, along the air flow direction, the distance from at least the part of the first air supply guiding surface 13a close to the air outlet 112 to the middle partition 21 gradually increases; and / or, along the air flow direction, the distance from at least the part of the second air supply guiding surface 13b close to the air outlet 112 to the middle partition 21 gradually increases, causing the air supply part 102 to gradually tilt away from the air inlet part 101.

[0115] Since the heat exchanger 40 is inclined in the air outlet cavity 202, the air flow tilts downward to the left after flowing out of the heat exchanger 40. In this application, the air supply part 102 is also set in an inclined form. From the perspective of the air flow path, the inclination angle of the air supply part 102 is generally consistent with the air flow direction on the air outlet side of the heat exchanger 40, which can reduce the turning of the air flow, reduce the wind resistance, and is more conducive to the delivery of the air flow, thereby reducing the noise.

[0116] In addition, the inclined setting of the air supply part 102 away from the air inlet part 101 also increases the distance between the air inlet and the air supply, preventing the air flows of the air inlet and the air supply from flowing through each other under the panel assembly 10.

[0117] In some embodiments, referring to Figure 10 , in the longitudinal section passing through the fan 30 and the heat exchanger 40, the ratio of the distance L1 from any point at the windward end of the heat exchanger 40 to one end (upper end or lower end) of the heat exchanger 40 to the length L of the heat exchanger 40 is defined as the area ratio, and the area where the extension line of the air outlet of the fan 30 intersects the windward end of the heat exchanger 40 is the fan facing area.

[0118] The area ratio of the fan facing area is 1 / 4 - 2 / 3. In this way, the air outlet of the fan 30 can face the middle area of the heat exchanger 40, ensuring the smoothness of the air flow. If the air outlet area of the fan 30 corresponds to the end of the heat exchanger 40, then the air flow will blow more to the corners of the air duct, which is not conducive to the air flow.

[0119] In some embodiments, the inclination angle of the heat exchanger 40 relative to the horizontal direction is α; the inclination angle of the air supply part 102 relative to the vertical direction is β; α and β satisfy: |α - β| ≤ 20°C. In this way, the air flow direction on the air outlet side of the heat exchanger 40 can be generally consistent with the flow direction of the air supply part, ensuring the smoothness of the air flow.

[0120] Referring to Figure 11, this figure shows the wind speed distribution inside the air conditioner. It can be seen from this figure that in the air duct of the present application, there is basically no vortex generation in the wind speed flow field, and the air flow is relatively smooth.

[0121] According to an embodiment of the present application, at least a part of the first air supply guiding surface 13a and / or the second air supply guiding surface 13b near the air supply outlet 112 can be arc-shaped, which is beneficial to smooth and unobstructed air supply. For example, the lower part of the first air supply guiding surface 13a in the figure is arc-shaped.

[0122] In other embodiments, the second air supply guiding surface 13b can be an inclined plane.

[0123] According to an embodiment of the present application, refer to Figure 12 and Figure 13 , the water receiving tray 50 is generally located below the right part of the heat exchanger 40, and directly below the left part of the heat exchanger 40 is the air supply part 102. The condensed water generated in the upper part of the heat exchanger 40 will flow down along the fins into the water receiving tray 50.

[0124] However, when condensed water is generated on the refrigerant pipes exposed outside the end plate 41 of the heat exchanger 40, since there is no guidance for this part of the condensed water, it may directly drip down.

[0125] For the convenience of description, the part of the refrigerant pipe exposed outside the end plate 41 is called the exposed pipe, and the exposed pipe located at the top is called the top exposed pipe 42.

[0126] For the front top exposed pipe 42, the condensed water generated by it will flow down into the auxiliary collection area 54 of the water receiving tray 50.

[0127] However, since there will be a connection gap S at the connection between the water receiving tray 50 and the side wall of the housing 20, when the condensed water near the top directly drips down, it is very likely to spread out from this connection gap S, bringing a bad user experience to the user.

[0128] Therefore, in some embodiments of the present application, refer to Figures 13 to 16 , the air conditioner further includes a water guiding plate 62. The water guiding plate 62 is arranged below the top exposed pipe 42 and is used to guide the condensed water generated by the top exposed pipe 42 into the water receiving tray 50.

[0129] The water guiding plate 62 is inclined. In the projection on the inner bottom surface of the water receiving groove in the water receiving tray 50, the top edge of the top exposed pipe 42 is located within the contour of the water guiding plate 62, and the lower end of the water guiding plate 62 is located within the water receiving groove.

[0130] Among them, the top edge of the top exposed pipe 42 being located within the contour of the water guiding plate 62 can ensure that the condensed water generated by the top exposed pipe 42 will drip onto the water guiding plate 62; and the lower end of the water guiding plate 62 being located within the water receiving groove can enable the water guiding plate 62 to divert the condensed water to the water receiving tray 50.

[0131] In the present application, by providing a water guide plate 62 below the top-exposed pipe 42, the condensed water dripping from the top-exposed pipe 42 can be guided into the water receiving tray 50, preventing the condensed water from spreading out from the connection gap S between the water receiving tray 50 and the housing 20.

[0132] The inclination direction of the water guide plate 62 can be parallel to the inclination direction of the heat exchanger, that is, inclined from top to bottom towards the air inlet side.

[0133] According to an embodiment of the present application, specifically referring to Figure 14 and Figure 15 , in the projection on the inner bottom surface of the water receiving groove of the water receiving tray 50, there is a gap d1 between the top edge of the top-exposed pipe 42 and the top of the water guide plate 62, which can prevent the condensed water dripping from the top-exposed pipe 42 from splashing out from the top of the water guide plate 62.

[0134] Referring to Figure 16 , there is a gap d2 between the lower end of the water guide plate 62 and the edge of the water receiving groove, which can prevent the condensed water from splashing from the lower end of the water guide plate 62 to the connection gap S.

[0135] d2 can be less than half of the width of the diversion area 52 of the water receiving tray 50, so as to reduce the length of the water guide plate 62, save materials and reduce costs.

[0136] In some embodiments, the water guide plate 62 is connected to the end plate 41.

[0137] As an example, the end plate 41 is a sheet metal plate, and the edge of the end plate 41 can be bent outwards to form the water guide plate 62.

[0138] As an example, the lower end edge of the end plate 41 has a second flanging, and the water guide plate 62 is connected to the second flanging.

[0139] According to an embodiment of the present application, the air conditioner further includes a support plate 60, and the support plate 60 is connected between the water receiving tray 50 and the end plate 41 of the heat exchanger 40, and the support plate 60 plays a role in supporting and fixing the end plate 41.

[0140] The water guide plate 62 is connected to the support plate 60. The water guide plate 62 can be connected to the top of the support plate 60.

[0141] In some other embodiments, the upper end of the support plate 60 has a first flanging 61, the first flanging 61 abuts against the second flanging, and then is fixedly connected by fasteners such as screws. A part of the first flanging 61 forms the water guide plate 62.

[0142] In addition, the support plate 60 and the end plate 41 can also be connected by a combination of hooks and screws: a hook is provided on the first flange 61, and a through groove is provided on the second flange, and the hook is adapted to be in the hook groove. The cooperation between the hook and the hook groove can play a positioning and limiting role, which facilitates the connection operation of the support plate 60 and the end plate 41, and can also save the number of screws and improve the disassembly and assembly efficiency.

[0143] The bottom end of the support plate 60 has a bottom flange, which abuts against the water receiving tray 50. The arrangement of the bottom flange can increase the abutment area between the support plate 60 and the water receiving tray 50, thereby improving the reliability and stability of the connection.

[0144] The left end of the support plate 60 has a side flange, and the side flange can be connected to the side wall of the shell 20 by screws to ensure the stability of the support plate 60 in the shell 20.

[0145] According to an embodiment of the present application, the edges of the water guide plate 62 are rounded to avoid scratching or cutting the pipeline.

[0146] Condensation generated by the exposed top tube 42 at the rear end will drip onto the air supply unit 102. A water guide plate 62 is also provided at the rear end of the heat exchanger 40 to guide the condensation to the water receiving tray 50, thereby preventing the condensation generated by the exposed top tube 42 from dripping onto the air supply unit 102.

[0147] In some embodiments, the air conditioner is also suitable for bathroom environments that require an exhaust function. Therefore, the air conditioner may include an exhaust fan and an exhaust channel for exhausting indoor air.

[0148] Reference Figure 17 In the figure, solid arrows indicate the direction of heat exchange airflow, and dashed arrows indicate the direction of exhaust airflow. In related art, an exhaust port 712 is provided on the sidewall of the air outlet chamber 202, and the exhaust port 712 is connected to the outside through a pipe. When the exhaust port 712 is open, the fan 30 drives the air out of the exhaust port 712 to achieve the exhaust function. However, in this structure, the exhaust duct and the heat exchange duct share the same air channel.

[0149] When the temperature control function and the exhaust function of the air conditioner are turned on at the same time, after the airflow passes through the heat exchanger 40, part of it is discharged from the exhaust port, and the other part is sent to the room. The exhaust airflow also passes through the heat exchanger 40 for heat exchange, which will cause energy waste and reduce the heat exchange efficiency of the air conditioner.

[0150] When the air conditioning temperature control function is turned off and only the exhaust function is in operation, or when the air conditioning temperature control function and the exhaust function are turned on at the same time, the wind resistance will increase when the airflow passes through the heat exchanger 40, resulting in a decrease in exhaust efficiency.

[0151] In order to avoid the above problems, in some embodiments of the present application,Figure 18 In the figure, the solid arrows indicate the flow direction of the heat exchange air flow, and the dashed arrows indicate the flow direction of the exhaust air flow. The housing assembly further includes an exhaust chamber 711, which is communicated with the outside, and the exhaust chamber 711 is directly communicated with the air inlet chamber 201 without passing through the air outlet chamber 202.

[0152] An exhaust fan 72 is provided in the exhaust chamber 711, and the exhaust fan 72 is used to urge the indoor air to be discharged from the exhaust chamber 711 to the outside.

[0153] When the exhaust fan 72 is operating and the fan 30 is not operating, the indoor air enters from the air inlet grille 14, then flows along the air inlet part 101 into the air inlet chamber 201, continues to flow into the exhaust chamber 711, and finally is discharged to the outside.

[0154] When the exhaust fan 72 and the fan 30 are operating, the indoor air enters from the air inlet grille 14, then flows along the air inlet part 101 into the air inlet chamber 201. A part of the air flows into the air outlet chamber 202 and then is circulated back into the room through the air supply outlet 112, and a part of the air flows into the exhaust chamber 711 and is finally discharged to the outside.

[0155] In this application, by providing an exhaust chamber 711 directly communicated with the air inlet chamber 201, when exhausting, the exhaust air flow does not pass through the heat exchanger 40 of the air outlet chamber 202, but is directly discharged from the exhaust chamber 711, improving the exhaust efficiency.

[0156] In some embodiments, the housing assembly may include an exhaust housing 71, the exhaust housing 71 forms the exhaust chamber 711, and the exhaust housing 71 and the outer side wall of the housing 20 may be integrally formed.

[0157] In the related art, referring to Figure 19 , for some air conditioners, the heat exchange air flow and the exhaust air flow are completely independent. The part of the air inlet chamber 201 corresponding to the air inlet grille 14 and the part of the exhaust chamber 711 corresponding to the air inlet grille 14 are different. In this way, the two air flows are completely independent.

[0158] However, the housing assembly with this structure needs to be redesigned and processed, which will increase the cost and cannot meet the requirement of directly adding an exhaust structure to an existing air conditioner (without an exhaust function).

[0159] In the embodiments of this application, the exhaust air flow and the heat exchange air flow share the air supply part 102 and the air inlet chamber 201, and an exhaust component 70 can be directly added to an existing air conditioner to meet the exhaust function of the air conditioner.

[0160] Referring to Figures 20 to 22, the exhaust assembly 70 includes an exhaust housing 71. The exhaust housing 71 is connected to the side wall of the housing 20 that forms the air inlet chamber 201. The space inside the exhaust housing 71 forms an exhaust chamber 711. An exhaust fan 72 can be arranged inside the exhaust housing 71, and an exhaust port 712 is provided on the side wall of the exhaust housing 71.

[0161] In occasions where there is no need for an exhaust function, the exhaust assembly 70 can be not installed, and the air conditioner without the exhaust assembly 70 can be installed in the usage scenario; in occasions where an exhaust function is required, the exhaust assembly 70 can be directly assembled onto the housing 20, which meets the requirements of various scenarios and can reduce costs.

[0162] In this application, the housing 20 and the exhaust housing 71 are of a two-piece connection structure, which can achieve the on-demand installation of the exhaust assembly 70, expand the universality of the product, and reduce costs.

[0163] According to an embodiment of the present application, the exhaust chamber 711 and the air inlet chamber 201 are connected through an exhaust connection part 203.

[0164] The exhaust connection part 203 can be arranged on the side wall of the housing 20 opposite to the middle partition 21. In this way, the separation paths of the heat exchange air flow and the exhaust air flow are exactly opposite, ensuring that the two air flows do not interfere with each other.

[0165] Specifically, the housing 20 and the exhaust housing 71 are arranged horizontally. For example, the housing 20 and the exhaust housing 71 are arranged left and right, and the exhaust housing 71 is connected to the right end of the housing 20.

[0166] The air outlet chamber 202 and the exhaust chamber 711 are respectively located on the left and right sides of the air inlet chamber 201. The heat exchange air flow flows from the air inlet chamber 201 to the left into the air outlet chamber 202, and the exhaust air flow flows from the air inlet chamber 201 to the right into the exhaust chamber 711.

[0167] In some embodiments, the exhaust housing 71 is in the shape of a rectangular parallelepiped box. One end of the exhaust housing 71 facing the housing 20 is open, and the exhaust housing 71 can be connected to the housing 20 through fasteners such as screws.

[0168] The exhaust connection part 203 is a through hole provided on the right side wall of the housing 20.

[0169] When projected on the right side wall of the housing 20, the outer contour of the exhaust housing 71 does not exceed the outer contour of the housing 20. In this way, it can be ensured that the dimensions of the air conditioner in the front-back direction and the up-down direction remain unchanged, and only the dimension in the left-right direction is increased.

[0170] In some embodiments, the exhaust port 712 may be provided on the side wall of the exhaust housing 71 opposite to the exhaust connection portion 203. Exemplarily, the exhaust connection portion 203 is located on the right side wall of the housing 20, and the exhaust port 712 is provided on the right side wall of the exhaust housing 71. Conforming to the overall trend of the exhaust air flow flowing to the right can make the exhaust smoother, thereby reducing the air flow noise at the air conditioner.

[0171] It should be noted that the exhaust port 712 may also be provided on the front side wall or the rear side wall of the exhaust housing 71.

[0172] In some embodiments, the fan 31 is a centrifugal fan. Exemplarily, the air intake of the fan 31 is located on the front and rear sides, and the exhaust port of the fan 31 faces the left side. That is to say, the heat exchange air flow will enter from the front and rear sides of the fan 31.

[0173] The exhaust connection portion 203 includes a first exhaust connection portion 204; in the projection on the side wall where the exhaust connection portion 204 is located, the first exhaust connection portion 204 is located within the contour of the fan 31. That is to say, the first exhaust connection portion 204 is located directly to the right of the fan 31. In this way, the exhaust air flow flows into the first exhaust connection portion 204 from the right side of the fan 31, and the heat exchange air flow flows into the fan 31 from the front and rear sides of the fan 31, so that the paths of the heat exchange air flow and the exhaust air flow in the air intake chamber 201 are separated as much as possible, avoiding the mutual influence of the two air flows in the air intake chamber 201 when the fan 31 and the exhaust fan 72 work simultaneously.

[0174] According to an embodiment of the present application, the exhaust fan 72 includes an exhaust fan 731 and an exhaust motor 722. The exhaust motor 722 is connected to the exhaust fan 731 and is used to drive the exhaust fan 731 to rotate.

[0175] The exhaust fan 731 may be a centrifugal fan. Exemplarily, the air intake of the exhaust fan 731 is located on the front and rear sides of the exhaust fan 731, and the air outlet of the exhaust fan 731 faces the right side, opposite to the exhaust port 712.

[0176] The axis of the exhaust fan 731 is generally parallel to the axis of the fan 31, and the air outlet directions of the two are opposite.

[0177] In some embodiments, in the projection on the side wall where the exhaust connection portion 204 is located, the air intake end of the exhaust fan 731 does not coincide with the first exhaust connection portion 204. The exhaust fan 731 and the first exhaust connection portion 204 are arranged horizontally in the front and rear directions.

[0178] In this way, the exhaust air flow blown into the exhaust chamber 711 by the first exhaust connection 204 is located upstream of the air intake of the exhaust fan 731, ensuring that the exhaust air flow enters the exhaust fan 731 more smoothly.

[0179] In some embodiments, on the projection of the side wall where the exhaust connection portion 204 is located, at least part of the exhaust fan 731 and the fan 31 do not overlap, so that the exhaust fan 731 and the fan 31 are staggered as much as possible in the front-back direction. This can make the suction openings of the exhaust fan 731 and the fan 31 on the same side be as far apart as possible, so as to separate the exhaust air flow and the heat exchange air flow in the air inlet cavity 201.

[0180] In one example, the exhaust fan 731 and the fan 31 are completely staggered. For example, if the exhaust fan 731 is closer to the front side than the fan 31, then the front suction opening of the exhaust fan 731 and the front suction opening of the fan 31 are relatively far apart. However, this completely staggered arrangement will make the size of the air conditioner in the front-back direction relatively large.

[0181] Therefore, in another example, the exhaust fan 731 and the fan 31 are partially staggered, and at least half of the exhaust fan 731 is staggered from the fan 31 in the front-back direction, so that the distance between the two can be made as large as possible without increasing the size of the air conditioner.

[0182] The exhaust connection portion 203 may include a second exhaust connection portion 205, and the second exhaust connection portion 205 is located on the side of the exhaust fan 731 away from the fan 31. For example, if the exhaust fan 731 is closer to the front side than the fan 31, the first exhaust connection portion 204 is located on the rear side of the exhaust fan 731, and the second exhaust connection portion 205 is located on the front side of the exhaust fan 731.

[0183] The exhaust air flow flows from the first exhaust connection 203 to the rear suction opening of the exhaust fan 731, and the exhaust air flow flows from the second exhaust connection portion 205 to the front suction opening of the exhaust fan 731.

[0184] According to an embodiment of the present application, on the projection of the side wall where the exhaust connection portion 203 is located, the second exhaust connection portion 205 does not overlap with the suction end of the exhaust fan 731. In this way, the air flow can directly blow to the front of the front suction opening of the exhaust fan 731 from the second exhaust connection portion 205, ensuring that the exhaust air flow flows more smoothly.

[0185] However, if the second exhaust connection portion 205 and the exhaust fan 731 are completely staggered in the front-back direction, in one case, in order to achieve a completely staggered arrangement, the size of the air conditioner in the front-back direction needs to be increased; in another case, in order not to increase the size of the air conditioner in the front-back direction, the front-back size of the second exhaust connection portion 205 will be relatively small, resulting in a reduction in the exhaust air volume.

[0186] Therefore, in another embodiment, the second exhaust connection portion 205 partially overlaps with the exhaust fan 731, and the overlapping area of the second exhaust connection portion 205 and the exhaust fan 731 is less than half of the area of the second exhaust connection portion 205. In this embodiment, although part of the exhaust air flow will be blocked by the exhaust fan 731, the air volume is ensured and the size of the air conditioner does not need to be increased.

[0187] In some embodiments, the relative positions of the fan 31 and the motor 32 are opposite to the relative positions of the exhaust fan 731 and the exhaust motor 722. For example, the motor 32 is located on the front side of the fan 31, and the exhaust motor 722 is located on the rear side of the exhaust fan 731.

[0188] The first exhaust connection portion 204 corresponds to the fan 31, and the second exhaust connection portion 204 corresponds to the motor 32. On the projection of the side wall where the exhaust connection portion 203 is located, the first exhaust connection portion 204 and the second exhaust connection portion 204 are respectively located on both sides of the exhaust fan 731.

[0189] In this way, on the premise of ensuring a compact structure, the exhaust air flow and the heat exchange air flow are separated as much as possible in the air inlet chamber 201.

[0190] In some embodiments, a wind valve is provided at the exhaust port 712, which can open or close the exhaust port 712. When the exhaust fan 731 is working, the wind valve is in the open state, and when the exhaust fan 731 is not working, the wind valve is in the closed state.

[0191] If the seal at the wind valve is not good, it is very easy for dirty air to backflow into the air conditioner. Therefore, referring to Figure 21 and Figure 23 , in the present application, the wind valve adopts a check valve 73. The check valve 73 automatically opens under the blowing of the exhaust air flow and automatically closes when there is no exhaust air flow in the exhaust passage, which can prevent the backflow of dirty air.

[0192] In some embodiments, the check valve 73 includes a valve body 731 and a blade 732. The blade 732 is movably arranged in the valve body 731. The blade 732 has a closed position and an open position. When in the closed position, the blade 732 closes the valve body 731, and when in the open position, the blade 732 opens the valve body 731.

[0193] When the exhaust fan 731 is working, the exhaust air flow can blow the blade 732 to the open position; the blade 732 is inclined vertically, and when there is no exhaust air flow, the blade 732 can automatically be in the closed position under the action of gravity.

[0194] In some embodiments, the check valve 73 may include a spring 733. The spring 733 is connected to the blade 732 and applies an elastic force towards the closed position to the blade 732. The elastic force of the spring 733 keeps the blade 732 in the closed position, which can enhance the sealing performance of the blade 732 in the closed position.

[0195] According to an embodiment of the present application, the check valve 73 is connected to the outside of the exhaust housing 71 corresponding to the exhaust port 712.

[0196] The valve body 731 includes a cylindrical portion 7311 and a square plate portion 7312 connected to the outer circumference of the cylindrical portion 7311. The square plate portion 7312 is connected to the exhaust housing 71 through fasteners such as screws.

[0197] In some embodiments, a stop portion 7313 is provided inside the cylindrical portion 7311. The stop portion 7313 includes an annular plate 7314 and a partition rib 7315. The annular plate 7314 is annular and connected to the inner wall of the cylindrical portion 7311. The partition rib 7315 is vertically connected inside the annular plate 7314. The annular plate 7314 and the partition rib 7315 enclose two communication ports.

[0198] The blade 732 is semicircular. Two blades 732 are respectively arranged corresponding to the two communication ports for opening or closing the communication ports.

[0199] The chord length end of the blade 732 is rotatably connected relative to the partition rib 7315, and the blade 732 is connected to the air outlet side of the stop portion 7313.

[0200] The stop portion 7313 is inclined towards the air outlet side from top to bottom. When there is no exhaust air flow, the blade 732 is in the closed position under the action of gravity. In the closed position, the blade 732 abuts against the stop portion 7313 to close the communication port. When there is exhaust air flow, impacted by the exhaust air flow, the blade 732 rotates in a direction away from the stop portion 7313 to open the communication port.

[0201] In some embodiments, the spring 733 is a torsion spring. Both ends of the spring 733 have acting portions 7331 extending outward along the tangent, and the two acting portions are at 180°.

[0202] A connecting rod 734 is connected to the partition rib 7315. The spring 733 is sleeved on the connecting rod 734. The two acting portions 7331 respectively abut against the two blades 732. Under the action of the elastic force of the spring 733, the blade 732 can be pressed against the stop portion 7313.

[0203] The inventive concept of the present application:

[0204] In this application, by making the bottom wall of the water receiving tray 50 protrude downward into the concave cavity 18 of the panel assembly 10, the bottom end of the heat exchanger 40 can extend downward following the bottom wall of the water receiving tray 50, thereby increasing the size of the heat exchanger 40. On the premise of ensuring that the volume of the air conditioner remains unchanged, the heat exchange area of the heat exchanger 40 is increased, and the heat exchange effect is improved.

[0205] In this application, by setting the guiding section 522 on the inner bottom wall of the water receiving tray 50 on the air outlet side of the heat exchanger 40 to be arc-shaped, the air flow at the bottom can smoothly transition and blow out along the guiding section 522, increasing the air flow area and eliminating vortices and noise.

[0206] In this application, by setting the curvature C range of the guiding section 522 on the water receiving tray 50: C≥0.002, it can be ensured that the air at the bottom on the air outlet side of the heat exchanger 40 is not blocked by the structure of the water receiving tray, which is beneficial to air outlet and ensures the heat exchange performance of the heat exchanger.

[0207] In this application, by setting the curvature C range of the guiding section 522 on the water receiving tray 50: C≤0.014, the impact of the air flow on the water receiving tray 50 can be avoided.

[0208] In this application, by setting the air outlet of the fan 30 to face the position of 1 / 4 to 2 / 3 of the heat exchanger 40, the air outlet of the fan 30 can face the middle area of the heat exchanger 40, ensuring the smoothness of the air flow and improving the heat exchange efficiency.

[0209] In this application, by setting the inclination angle of the heat exchanger 40 relative to the horizontal direction to be α, and the inclination angle of the air supply part 102 relative to the vertical direction to be β satisfying: |α - β|≤20°C. In this way, the air flow direction on the air outlet side of the heat exchanger 40 can be made substantially consistent with the flow direction of the air supply part, ensuring the smoothness of the air flow.

[0210] In this application, by arranging a water guide plate 62 below the top exposed pipe 42, the condensed water dripping from the top exposed pipe 42 can be guided into the water receiving tray 50, avoiding the spread of the condensed water from the connection gap S between the water receiving tray 50 and the housing 20.

[0211] In this application, by arranging an exhaust cavity 711 directly connected to the air inlet cavity 201, when exhausting, the exhaust air flow does not need to pass through the heat exchanger in the air outlet cavity 202, but is directly discharged from the exhaust cavity 711, improving the exhaust efficiency.

[0212] In this application, on the projection of the side wall where the exhaust connection part 204 is located, the first exhaust connection part 204 is located within the contour of the fan 31, making the paths of the heat exchange air flow and the exhaust air flow in the air inlet cavity 201 as separated as possible, avoiding the mutual influence of the two air flows in the air inlet cavity 201 when the fan 31 and the exhaust fan 72 work simultaneously.

[0213] In this application, on the projection of the side wall where the exhaust connection part 204 is located, at least part of the exhaust fan 731 and the fan 31 do not overlap, so that the exhaust fan 731 and the fan 31 are staggered as much as possible in the front-back direction, which can make the air inlets of the exhaust fan 731 and the fan 31 on the same side be separated as much as possible, and make the exhaust air flow and the heat exchange air flow be separated as much as possible in the air inlet chamber 201.

[0214] In this application, by providing a check valve 73 at the exhaust port 712, the check valve 73 is automatically opened by the blowing of the exhaust air flow and automatically closed when there is no exhaust air flow in the exhaust passage, which can prevent the backflow of dirty air.
