DETAILED DESCRIPTION

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The following describes this application using the indoor unit in a split unit and the duct unit with the indoor unit installed on the ceiling as an example:

[0039] 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.

[0040] 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.

[0041] In the present application, the side panel of the shell 10 having the air outlet 12 is the second side panel 15 , a side panel adjacent to the second side panel 15 can be connected to the drain pipe joint 60 , and the side panel connected to the drain pipe joint 60 is the first side panel 14 .

[0042] 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.

[0043] 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 .

[0044] The air conditioner includes a fan 20 disposed in the air inlet cavity. The fan 20 may be a centrifugal fan. The air flow at the exhaust end of the fan 20 is blown toward the air outlet cavity through the middle partition plate 13.

[0045] 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.

[0046] 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.

[0047] 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 .

[0048] In some embodiments, reference Figure 4 The water receiving tray 40 may include a guide portion 41 , which is located below the heat exchanger 30 , and the condensation water flowing toward the heat exchanger 30 may drip onto the guide portion 41 .

[0049] The water collecting tray 40 may include a water collecting portion 42 connected to one side of the guide portion 41. 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 42 and the guide portion 41 may be left-right.

[0050] The inner groove bottom of the guide portion 41 may be arranged from high to low in a direction close to the water collecting portion 42 , so that the condensed water of the guide portion 41 flows toward the water collecting portion 42 .

[0051] The air conditioner may include a drainage assembly 50 , which may be disposed above the water collecting portion 42 to drain condensed water in the water collecting portion 42 .

[0052] Reference Figures 4 to 6 The drainage assembly 50 may include a water pump 51, the water suction end of the water pump 51 may correspond to the drainage groove of the water collecting part 42, and the drainage end of the water pump 51 may be connected to the drainage pipe joint 60 on the first side plate 14. The drainage pipe joint may be connected to an external drainage pipe. When the water pump 51 is working, the condensed water flowing to the water collecting part 42 can be discharged from the housing 10 through the drainage pipe.

[0053] The drainage assembly 50 may include a float switch 52 for sending a water level signal. When the water level of the water receiving tray 40 reaches a preset water level of the float switch 52, the float switch 52 will change state, for example, from connected to disconnected.

[0054] When the float switch 52 changes from connected to disconnected, the water pump 51 starts to work, thereby draining the water in the water receiving tray 40 in time, and also avoiding energy waste and working noise caused by the water pump 51 being turned on all the time or frequently turned on.

[0055] The drain assembly 50 may include a bracket 53, and the bracket 53 is used to fix the water pump 51 in the housing 10. The bracket 53 is connected to the housing 10, and the water pump 51 is fixed on the bracket 53.

[0056] In some embodiments, reference Figure 7 The bracket 53 includes a first fixing plate 531, which is connected to the first side plate 14 of the shell 10. The first fixing plate 531 and the first side plate 14 can be connected by fasteners such as screws, or the first fixing plate 531 and the first side plate 14 can be connected by welding.

[0057] The first fixing plate 531 is disposed in a transverse direction. A vertically extending mounting plate 532 is connected to one end of the first fixing plate 531 close to the first side plate 14 . The mounting plate 532 abuts against the first side plate 14 .

[0058] The bracket 53 may be a sheet metal part, and the first fixing plate 531 and the mounting plate 532 are made by bending 90 degrees.

[0059] The edge of the mounting plate 532 may be provided with a flange, which extends inwardly of the housing 10 and away from the first side plate 14. The height of the flange may be 5 to 10 mm, and its main function is to facilitate installation and positioning when installing the bracket 53. In addition, the provision of the flange can increase the strength of the mounting plate 532 and ensure the structural strength of the mounting plate 532.

[0060] In some embodiments, a connecting plate 511 is provided on the water pump 51 for connecting to the first fixing plate 531 of the bracket 53 .

[0061] The connecting plate 511 may be located at the top of the water pump 51. At least three first mounting holes 512 are provided on the connecting plate 511, and the connection lines of the three first mounting holes 512 are distributed in a triangle, which can ensure the stability and reliability of the connection.

[0062] At the two opposite ends of the connecting plate 511, one mounting hole 512 can be set close to one end of the connecting plate 511, and the other two first mounting holes 512 can be set close to the other end of the connecting plate 511, which is easier to position during processing, facilitates processing and manufacturing, and reduces processing costs.

[0063] The first fixing plate 531 may be provided with second mounting holes 5311 corresponding to the first mounting holes 512 in a one-to-one manner.

[0064] The vibration-absorbing foot pad 54 is inserted into the first mounting hole 512 and the second mounting hole 5311. Fasteners such as bolts 55 can be inserted into the vibration-absorbing foot pad 54 to connect the mounting plate 532 and the first fixing plate 531.

[0065] When the bracket 53, the first side plate 14 and the like adopt a thin plate structure similar to sheet metal, the low-frequency vibration generated by the operation of the water pump 51 is transmitted to the sheet metal, radiating a low-frequency humming sound. The vibration-damping foot pad 54 can play a role in isolation and vibration reduction, reducing the vibration rate between the water pump 51 and the bracket 53, thereby reducing the low-frequency noise caused by the vibration of the water pump 51.

[0066] In some embodiments, the connecting plate 511 is provided with a notch 413 communicating with the first mounting hole 512. The second mounting hole 5311 has the same structure as the first mounting hole 512.

[0067] Reference Figure 6 and Figure 8 The vibration-damping foot pad 54 is cylindrical and has at least two constricted limiting portions 541 on its outer circumference. The two limiting portions 541 are respectively a first limiting portion 5411 and a second limiting portion 5412. The first limiting portion 5411 is correspondingly installed in the second mounting hole 5311. The second limiting portion 5412 is correspondingly installed in the first mounting hole 512.

[0068] The diameter of the limiting portion 541 may be 1-3 mm smaller than the diameter of the first mounting hole 512 (or the second mounting hole 5311 ).

[0069] The limiting portion 541 of the vibration-damping foot pad 54 is installed into the first installation hole 512 and the second installation hole 5311 through the notch 413 .

[0070] The bolt 55 is inserted into the inner through hole of the vibration-damping foot pad 54 , and the end of the bolt 55 is connected with a nut, so that the bolt 55 connects the connecting plate 511 and the first fixing plate 531 .

[0071] In some embodiments, the width of the notch 413 may be smaller than the diameter of the bolt 55, thereby preventing the bolt 55 and the shock-absorbing foot pad 54 from slipping out of the first mounting hole 512 or the second mounting hole 5311 from the notch 412. The width of the notch 413 may be set to half the diameter of the first mounting hole 512 or the second mounting hole 5311.

[0072] In some embodiments, reference Figure 8 and Fig. 9 The vibration-damping foot pad 54 includes a first vibration-damping section 542 , a first limiting portion 5411 , a second vibration-damping section 543 , a second limiting portion 5412 and a third vibration-damping section 544 which are sequentially arranged along the axial direction.

[0073] The first vibration-damping section 542 is located on the upper side of the first fixing plate 531 , the second vibration-damping section 543 is located between the first fixing plate 531 and the connecting plate 511 , and the third vibration-damping section 544 is located on the lower side of the connecting plate 511 .

[0074] When the bolt 55 is passed through the vibration-damping foot pad 54 from bottom to top, the first vibration-damping section 542 vibration-damping isolates the nut from the first fixing plate 531 , the second vibration-damping section 543 vibration-damping isolates the first fixing plate 531 and the connecting plate 511 , and the third vibration-damping section 544 vibration-damping isolates the connecting plate 511 from the bolt head of the bolt 55 .

[0075] In some embodiments, the length of the first vibration-damping section 542 is L1, the length of the second vibration-damping section 543 is L2, and the length of the third vibration-damping section 544 is L3.

[0076] When the connecting plate 511 shakes due to the vibration of the water pump 51, since the lateral area of ​​the first fixing plate 531 is relatively large, the probability of the connecting plate 511 touching the first fixing plate 531 is much greater than the probability of touching the bolt head with a smaller lateral area. Therefore, the distance between the first fixing plate 531 and the connecting plate 511 needs to be relatively large, that is, L2 needs to be greater than L3.

[0077] Similarly, since the nut has a relatively small transverse area and is located at an end far away from the vibration source (ie, the water pump 51 ), L2 is greater than L1 .

[0078] When the bolt 55 is installed from top to bottom, the bolt head is located at the upper end of the first vibration reduction section 542, and the nut is located at the lower end of the third vibration reduction section 544. At this time, the nut is located at the end away from the vibration source. Considering the bidirectional installation of the bolt 55, L2=L3 can be set.

[0079] L1 / L2≥the first parameter value. For example, the first parameter value is 1 / 4 or 1 / 3. If the ratio of L1 / L2 is too small and L1 is relatively short, the vibration isolation effect of the first vibration damping section 542 on the nut (or bolt head) and the first fixing plate 531 will be greatly weakened. L1 / L2≥the first parameter value, thereby ensuring the vibration isolation effect of the first vibration damping section 542.

[0080] Similarly, L3 / L2≥the first parameter value. For example, the first parameter value is 1 / 4 or 1 / 3. If the ratio of L3 / L2 is too small and L3 is relatively short, the vibration isolation effect of the third vibration damping section 544 on the bolt head (or nut) and the connecting plate 511 will be greatly weakened. L3 / L2≥the first parameter value, thereby ensuring the vibration isolation effect of the third vibration damping section 544.

[0081] L1 / L2≤the second parameter value, for example, the second parameter value is 1 / 3, 1 / 2, if the ratio of L1 / L2 is too large, L1 is relatively long, and the bolt 55 is relatively long and will occupy space. Similarly, L3 / L2≤the second parameter value.

[0082] In some embodiments, a through hole 5312 may be provided in the middle of the first fixing plate 531 , and the through hole 5312 may reduce the low-frequency radiation noise generated by the vibration of the water pump 51 transmitted to the first fixing plate 531 . The area of ​​the through hole 5312 may be 1 / 3 of the area of ​​the first fixing plate 531 .

[0083] In some embodiments, reference Figure 6 and Fig.10 , the float switch 53 is mounted on the bracket 53. The float switch 53 is fixed in the housing 10 through the bracket 53.

[0084] The bracket 53 may include a second fixing plate 533 connected to the first fixing plate 533 , and the float switch 53 is connected to the second fixing plate 533 .

[0085] The end of the first fixing plate 533 connected to the first side plate 14 is defined as the first end of the first fixing plate 533 , and the other end opposite to the first end is defined as the second end of the first fixing plate 533 . The second fixing plate 533 is connected to the second end of the first fixing plate 533 .

[0086] In some embodiments, the second fixing plate 533 includes a plate body 5331 extending vertically. The plate body 5331 may be formed by bending the second end of the first fixing plate 533 downward.

[0087] The second fixing plate 533 may include a transversely extending mounting portion 5332, which is connected to the bottom end of the plate body 5331 and is away from one side of the first fixing plate 533. The mounting portion 5332 may be formed by bending the bottom end of the plate body 5331 transversely.

[0088] A through U-shaped groove may be provided on the mounting portion 5332, and the float switch 52 is mounted on the U-shaped groove by a nut.

[0089] Since the float switch 52 and the water pump 51 are mounted on the same bracket 53 , the vibration generated during the operation of the water pump 51 will be transmitted to the float switch 52 through the bracket 53 , thereby affecting the detection accuracy of the float switch.

[0090] In some embodiments, the second fixing plate 533 can be connected to the second side plate 15 , which can further enhance the connection strength of the bracket 53 , reduce the impact of the vibration of the water pump 51 on the bracket 53 , and avoid the impact of the vibration of the water pump 51 on the float switch 52 .

[0091] If the bracket 53 is connected to the housing 10 only by one end of the bracket 53, the second fixing plate 533 of the bracket 53 is similar to a cantilever structure and is more susceptible to vibration. If the second fixing plate 533 of the bracket 53 is also connected to the housing 10, the relative connection position of the second fixing plate 533 and the housing 10 can be strengthened to prevent the float switch 52 on the second fixing plate 533 from being affected by vibration.

[0092] In some embodiments, a support portion 5333 is provided on the second fixing plate 533 , and the support portion 5333 is connected to the plate body 5331 , and can be formed by bending the plate body 5331 .

[0093] The plate body 5331 may abut against the second side plate 15 of the housing 10 and then be connected to the second side plate 15 via fasteners such as screws.

[0094] The mounting portion 5332 and the support portion 5333 may be located on both sides of the plate body 5331. The mounting portion 5332 is located on a side of the plate body 5331 away from the support portion 5333, which can ensure that the float switch 52 is close to the water pump 51 and located in the water receiving tray 40.

[0095] In some embodiments, reference Fig.11 On the projection of the first fixing plate 531, part of the water pump 51 is exposed from the second end of the first fixing plate 531, and the extension line of the plate body 5331 of the second fixing plate 533 passes through the exposed part of the water pump 51. In this way, the size of the first fixing plate 531 in the direction perpendicular to the first side plate 14 can be reduced, making the structure of the drainage assembly more compact.

[0096] The air conditioner of the present application is subjected to a noise comparison experiment with the air conditioner of the prior art.
