DETAILED DESCRIPTION

[0026] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0027] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0028] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The air conditioner in this application performs a refrigeration cycle of the air conditioner 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.

[0031] 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 the heat is released to the surrounding environment through the condensation process.

[0032] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid 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 utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0033] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0034] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0035] The air conditioner according to the embodiment of the present application may be an all-in-one unit in which an indoor unit and an outdoor unit are integrated in one housing, or may be a split unit in which the indoor unit and the outdoor unit are independently and separately installed.

[0036] The following describes this application by taking the indoor unit in a split unit and the indoor unit as a duct unit installed on the ceiling as an example:

[0037] Reference Figure 1 and Figure 2 The air conditioner according to the embodiment of the present application includes a housing 10 in which a plurality of components constituting a refrigeration cycle are installed.

[0038] The housing 10 is in a rectangular parallelepiped shape, and an air inlet 11 is provided on one of a set of opposite side surfaces of the housing 10, and an air outlet 12 is provided on the other side surface. Indoor air is introduced into the housing 10 through the air inlet 11, and is sent into the indoor space through the air outlet 12.

[0039] In an example of an installation scenario, the air inlet 11 can be connected to the air inlet grille of the ceiling decoration, so that indoor air can flow into the shell 10 through the air inlet grille and the air inlet 11. A flange can be set on the outside of the air outlet 12, and the flange can be connected to the air duct and extended from the air duct to the indoor space.

[0040] Reference Figure 3 A middle partition 13 may be provided in the shell 10 , and the space in the shell 10 is divided into an air inlet chamber and an air outlet chamber by the middle partition 13 , wherein the air inlet chamber is connected to the air inlet 11 , and the air outlet chamber is connected to the air outlet 12 .

[0041] The air conditioner includes a fan 20 disposed in the air inlet cavity. The fan 20 may be a centrifugal fan. The exhaust air flow of the fan 20 passes through the middle partition plate 13 and blows toward the air outlet cavity.

[0042] The air conditioner includes a heat exchanger 30 disposed in the air outlet cavity. The heat exchanger 30 is used to absorb heat from the air introduced into the housing 10 or transfer heat to the air.

[0043] The water receiving pan 40 may be disposed below the heat exchanger 30 to collect condensed water condensed in the heat exchanger 30. The water receiving pan 40 may be connected to a drain pipe connected to the outside of the housing 10 and drain the condensed condensed water to the outside of the housing 10.

[0044] Under the action of the fan 20 , the indoor air enters the air inlet cavity from the air inlet 11 , then flows into the air outlet cavity through the fan 20 , and flows to the air outlet 12 after heat exchange in the heat exchanger 30 .

[0045] In some embodiments, reference Figures 4 to 6 The water receiving tray 40 includes a water receiving shell 41. The upper end of the water receiving shell 41 is concave to form a water receiving groove 41a to accommodate condensed water.

[0046] The water receiving shell 41 can be made of plastic material and manufactured by integral injection molding.

[0047] The water receiving shell 41 includes a groove bottom wall 411. In the airflow direction, the air inlet end and the air outlet end of the groove bottom wall 411 are relatively high, and the middle section of the groove bottom wall 411 is relatively low.

[0048] The water receiving shell 41 includes a groove side wall 412, and the groove side wall 412 is connected to the opposite ends of the groove bottom wall 411. The groove side wall 412 and the groove bottom wall 411 surround the water receiving groove 41a.

[0049] In some embodiments, a cavity 41b is further provided on the water receiving shell 41, and the cavity 41b is located below the water receiving groove 41a. The groove bottom wall 411 separates the water receiving groove 41a and the cavity 41b.

[0050] The cavity 41b can be filled with a sound insulating member 42, which is a sound absorbing material. The sound absorbing material is a porous sound absorbing material, a two-component surface, polyacrylonitrile or other sound absorbing material.

[0051] In some embodiments, the water receiving shell 41 includes a cavity bottom wall 413 , and the cavity bottom wall 413 is located below the groove bottom wall 411 , and the cavity bottom wall 413 is spaced apart from the groove bottom wall 411 .

[0052] The water receiving shell 41 includes a cavity side wall 414, and the cavity side wall 414 is connected between the groove bottom wall 411 and the cavity bottom wall 413. The groove bottom wall 411, the cavity side wall 414 and the cavity bottom wall 413 form a cavity body 41b.

[0053] According to an embodiment of the present application, one side end of the cavity 41 b is open to facilitate filling the sound insulation member 42 into the cavity 41 b from the open end.

[0054] In other embodiments, different from the above embodiments, the water receiving shell 41 does not include the cavity bottom wall 413, and the cavity 41b is surrounded by the groove bottom wall 411 and the cavity side walls 414 connected around the groove bottom wall 411, that is, the lower end of the cavity 41b is open.

[0055] The sound insulation member 42 may be connected to the cavity 41b by bonding.

[0056] Reference Figure 7 By conducting a noise comparison experiment between the air conditioner of the present application and the air conditioner of the prior art, it was found that compared with the prior art, after the sound insulation member 42 was filled in the cavity 41b of the water receiving tray 40, the noise generated by the air conditioner of the present application was reduced, especially at a high windshield, the noise was reduced by about 1dB(A).

[0057] According to the embodiments of the present application, referring to Figure 8 The water receiving tray 40 may include a guide portion 401 , which is located below the heat exchanger 30 , and the condensation water flowing down from the heat exchanger 30 may drip onto the guide portion 401 .

[0058] The water collecting tray 40 may include a water collecting portion 402 connected to one side of the guide portion 401. For example, the direction of air flow through the heat exchanger is from back to front, and the arrangement direction of the water collecting portion 402 and the guide portion 401 may be left and right.

[0059] The inner groove bottom of the guide part 401 may be presented from high to low in the direction close to the water collecting part 402, so that the condensed water of the guide part 401 will flow to the water collecting part 402. A drainage component such as a water pump may be arranged above the water collecting part 402 to pump away the condensed water flowing to the water collecting part 402.

[0060] In some embodiments, reference Fig. 9 The bottom wall 411 of the water receiving tray 41a includes a water guiding section 4111, which slopes downward from an end away from the water collecting portion 402 to an end close to the water collecting portion 402, so that condensation water in the water guiding section 4111 can flow to the water collecting portion 402.

[0061] The bottom wall 411 of the water receiving tray 41a includes a connecting section 4112, which is connected to one end of the water guiding section 4111 close to the air inlet 11. The connecting section 4112 is inclined upward from one end close to the water guiding section 4111 to one end away from the water guiding section 4111, and the inclination angle of the connecting section 4112 relative to the horizontal direction is 25° to 50°.

[0062] Since the lowest end of the connecting section 4112 is connected to the water guiding section 4111 , the condensed water on the connecting section 4112 can flow to the water guiding section 4111 .

[0063] In some embodiments, the connecting section 4112 may include a first connecting section 4113, and the first connecting section 4113 is connected to the water guiding section 4111. The inclination angle b1 of the first connecting section 4113 is in the range of 40 to 50 degrees.

[0064] The connecting section 4112 may include a second connecting section 4114 connected to an end of the first connecting section 4113 away from the water guide section 4111. The inclination angle b2 of the second connecting section 4114 relative to the horizontal direction may be smaller than the inclination angle b1 of the first connecting section 4113, which is conducive to the flow of air flow at the connecting section 4112.

[0065] The height of the end of the water guiding section 4111 away from the first connecting section 4113 is h1; the height of the end of the water guiding section 4111 close to the first connecting section 4113 is h2, that is, the vertical distance from the bottom end of the first connecting section 4113 to the water guiding section 4111 is h2; the height of the first connecting section 4113 is h3.

[0066] h3 may be greater than h2. A smaller h2 may reduce the height of the water receiving tray 40, and a larger h3 may effectively support the heat exchanger 30. The ratio of h3 to h2 may be 2:1.

[0067] Reference Fig.10When the heat exchanger 30 is installed at an angle in the air outlet cavity, the bottom end of the heat exchanger 30 can abut against the connecting section 4112 , that is, the connecting section 4112 has the function of supporting the heat exchanger 30 .

[0068] The first connecting section 4113 and the second connecting section 4114 can form two different supporting angles for the heat exchanger 30 , thereby meeting the installation requirements of the heat exchanger 30 at different tilt angles.

[0069] In some embodiments, continue to refer to Fig. 9 The bottom wall 411 of the water receiving tray 41 may include a supporting section 4115 , and the supporting section 4115 is connected to one end of the water guiding section 4111 close to the air outlet 12 .

[0070] The support section 4115 is inclined downward from an end away from the water guiding section 4111 to an end close to the water guiding section 4111 , so that condensation water on the support section 4115 can flow into the water guiding section 4111 .

[0071] The inclination angle a1 of the support section 4115 relative to the horizontal direction is in the range of 3 to 10 degrees.

[0072] Combination Fig.11 When the heat exchanger 30 is installed vertically in the air outlet cavity, that is, the bottom end of the heat exchanger 30 is approximately horizontal, the bottom end of the heat exchanger 30 can abut against the support section 4115, that is, the support section 4115 has the function of supporting the heat exchanger 30. The support section 4115 is tilted at a small angle, which can support the heat exchanger 30 while allowing the condensed water to flow to the water guide section 4111.

[0073] In some embodiments, the bottom wall 411 of the water receiving tray 41 may include an arc segment 4116 , which facilitates the smooth flow of air.

[0074] According to an embodiment of the present application, the heat exchanger 30 may be bent multiple times in the up and down directions. Exemplarily, the heat exchanger 30 is generally in a W-shape rotated 90°.

[0075] The heat exchanger 30 includes a bottom air outlet surface 31 located at the air outlet side. The bottom air outlet surface 31 and the bottom surface of the heat exchanger 30 may be connected in an arc transition through an arc air outlet surface 32 .

[0076] The radius of the arc air outlet surface 32 may be consistent with the radius of the arc segment 4116 .

[0077] The bottom surface of the heat exchanger 30 abuts against one end of the support section 4115 close to the arc section 4116, and the arc air outlet surface 32 of the heat exchanger 30 contacts the arc section 4116. The arc section 4116 further strengthens the supporting effect of the water receiving tray 40 on the heat exchanger 30.

[0078] In some embodiments, the bottom wall 411 of the water receiving tray 41 may include a blocking section 4117 , and the blocking section 4117 is connected to an end of the arc section 4116 away from the supporting section 4115 .

[0079] The blocking section 4117 is inclined downward from an end away from the arc section 4116 to an end close to the arc section 4116 , so that condensation water on the blocking section 4117 can flow toward the arc section 4116 .

[0080] The inclination angle a1 of the blocking section 4117 relative to the horizontal direction is in the range of 50 to 60 degrees, which can prevent condensation water from flowing out of the water receiving tray 40 under the action of air flow.

[0081] In the present application, a cavity 41 b is provided on the water receiving tray 40 below the water receiving groove 41 a , and a sound insulating member 42 is filled in the cavity 41 b , thereby reducing the noise on one side of the heat exchanger 30 .

[0082] In the present application, a connecting section 4112 and a supporting section 4115 are respectively arranged on both sides of the water guiding section 4111. The connecting section 4112 has a larger inclination angle and can provide support for the inclined installed heat exchanger 30. The supporting section 4115 has a smaller inclination angle and is only used to guide water to the water guiding section 4111. The supporting section 4115 can provide support for the heat exchanger 30 installed horizontally at the bottom. Therefore, the water receiving tray 40 meets the requirements of various installation forms of the heat exchanger 30 and has the advantages of strong versatility and wide adaptability.
