Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an indoor air conditioning unit and an air conditioner having the indoor air conditioning unit. Background Technology

[0002] Air conditioners are common household appliances in people's daily lives. With the rapid development of technology, people's quality of life has been improved, and consumers' demand for air conditioners will become more diversified. The development trend of air conditioners is gradually moving towards diversification and efficiency. According to the installation method and application, air conditioners can be divided into: wall-mounted air conditioners, floor-standing air conditioners and window air conditioners.

[0003] To collect the condensate generated by the heat exchanger inside the air conditioner's indoor unit, a drip tray is installed, connected to a drain pipe to drain the condensate. Over time, dirt and scale build up in the drip tray, affecting the airflow quality and necessitating cleaning.

[0004] To facilitate cleaning of the drip tray, existing air conditioning indoor units use a detachable support module for the drip tray. However, because the drip tray needs to be stably and tightly fitted to the lower end of the heat exchanger, the existing support module supporting the drip tray often also supports the heat exchanger or heat exchange duct casing. This increases the difficulty of disassembling and assembling the support module, and the drip tray cannot be removed from the support module, further complicating the cleaning process and resulting in poor cleaning performance.

[0005] In addition, the existing support module with the drip tray is pulled out straight down from the bottom of the air conditioner indoor unit, which requires a relatively spacious operating space under the air conditioner indoor unit. However, the space under floor-standing air conditioners and window air conditioners is limited, which is not conducive to the disassembly and assembly of the support module and makes it impossible to clean the drip tray. Summary of the Invention

[0006] To achieve the first objective of this invention, this invention provides an indoor air conditioning unit that allows for the individual rotation and disassembly of the drip tray within a limited operating space.

[0022] A further design involves an air inlet on the front panel, positioned vertically between the upper air outlet and the lower air outlet grille.

[0029] To achieve the second objective of the present invention, the present invention provides an air conditioner, including an indoor unit, wherein the indoor unit is the aforementioned indoor unit.

[0030] The water receiving tray of the indoor unit of the air conditioner of the present invention is located below the heat exchanger and supported on the rear support. The lower end of the heat exchanger is inserted into the water receiving groove of the water receiving tray from the upper opening of the water receiving tray, so that the water receiving groove of the water receiving tray can hold the condensate generated by the heat exchanger and discharge it from the drain nozzle connected to the water receiving groove.

[0031] When the water tank needs cleaning, first remove the front panel from the rear support. Then, grasp the front end of the water tray to control its clockwise rotation relative to the rear support around the rotation axis, causing the rear end of the water tray to rotate downwards. Continue grasping the front end of the water tray to control its clockwise rotation relative to the rear support around the rotation axis, causing the upper opening of the rear end of the water tray to detach from the lower end of the heat exchanger. The water tray can then be easily removed from the rear support, thus easily removing the water tank. Because the water tank of this invention can be rotated and removed independently from the rear support in a limited operating space, and no other structural features hinder the cleaning of the water tank, the cleaning difficulty of the water tray is greatly reduced, allowing for thorough cleaning of the water tank and improving the cleaning effect of the water tray.

[0032] After the water tray is cleaned, grasp the front end of the water tray and rotate it so that the open end of the rear end faces down, pushing it into the rear support under the heat exchanger. Then, grasp the front end of the water tray and control it to rotate counterclockwise around the rotation axis relative to the rear support, so that the rear end of the water tray rotates upward, allowing the lower end of the heat exchanger to insert into the water tray's water groove through the open end. Continue grasping the front end of the water tray to control it to rotate counterclockwise around the rotation axis relative to the rear support, rotating the water tray upward to the preset target position, so that the water tray is properly supported on the rear support, thus easily installing the water tray. Then, close the front panel and install it on the front end of the rear support to restore the air conditioner indoor unit. Because the water tray has been thoroughly cleaned, the heat exchange performance of the air conditioner indoor unit can be improved.

[0033] Compared to existing linear extraction methods, this invention allows for the individual rotation and disassembly of the water tray relative to the rear support, requiring only a reduced operating space. This enables separate rotation and disassembly of the water tray within limited space, making it effectively applicable to wall-mounted, floor-standing, and window air conditioners, thus broadening its versatility. Furthermore, this design, where the water tray rotates relative to the rear support, does not affect the structural strength of any component of the indoor unit and does not add unnecessary parts, effectively ensuring the reliability of the indoor unit.

[0034] Therefore, the indoor unit of the air conditioner of the present invention can rotate and disassemble the water tray separately in a limited operating space, making the disassembly and assembly of the water tray simple and convenient, and greatly reducing the difficulty of cleaning the water tray, thereby improving the cleaning effect of the water tray, and thus improving the heat exchange performance, so as to enhance the user experience.

[0056] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0057] See Figures 1 to 18 In this embodiment, the indoor unit 10 of the air conditioner includes a casing and a heat exchanger 15, with the heat exchanger 15 located in the built-in cavity of the casing.

[0058] In this embodiment, the housing includes a front panel 11 and a rear support 18. The front panel 11 can be detachably fitted onto the front end of the rear support 18 and forms an internal cavity of the housing with the rear support 18. The heat exchanger 15 is installed on the rear support 18.

[0059] Furthermore, the indoor unit 10 of this embodiment also includes a water receiving tray 19. The water receiving tray 19 is rotatably and detachably supported on the rear support 18 and located below the heat exchanger 15, so that the lower end of the heat exchanger 15 is inserted into the water receiving groove 193 of the water receiving tray 19 through the upper opening of the water receiving tray 19. The water receiving tray 19 is provided with a drain nozzle 194 communicating with the water receiving groove 193. The rotating shaft extends in the left and right direction of the indoor unit 10.

[0060] like Figure 19 As shown, in this embodiment, the water receiving tray 19 of the indoor unit 10 of the air conditioner is located below the heat exchanger 15 and supported on the rear support 18. The lower end of the heat exchanger 15 is inserted into the water receiving groove 193 of the water receiving tray 19 from the upper opening of the water receiving tray 19. Thus, the water receiving groove 193 of the water receiving tray 19 can collect the condensate generated by the heat exchanger 15 and discharge it from the drain nozzle 194 that is connected to the water receiving groove 193.

[0061] When the water tank 193 needs to be cleaned, first remove the front panel 11 from the rear support 18, then grasp the front end of the water tray 19 to control the water tray 19 to rotate clockwise relative to the rear support 18 around the rotation axis, so that the rear end of the water tray 19 rotates downwards. Figure 20 As shown, the front end of the water receiving tray 19 is continuously grasped to control the water receiving tray 19 to rotate clockwise relative to the rear support 18 around the rotation axis, so that the upper opening of the rear end of the water receiving tray 19 disengages from the lower end of the heat exchanger 15, as shown. Figure 21 As shown, the water tray 19 can then be removed from the rear support 18, thereby easily removing the water trough 193. Since the water trough 193 in this embodiment can be rotated and removed independently from the rear support 18 within a limited operating space, and no other structural features hinder the cleaning of the water trough 193, the cleaning difficulty of the water tray 19 is greatly reduced, allowing for thorough cleaning of the water trough 193 and improving the cleaning effect of the water tray 19.

[0062] After the water receiving tank 193 has finished cleaning, grasp the front end of the water receiving tray 19 and rotate the rear end of the water receiving tank 193 with the open end facing down until it is pushed into the rear support 18 below the heat exchanger 15. Figure 21 As shown, the front end of the water receiving tray 19 is then grasped to control the water receiving tray 19 to rotate counterclockwise relative to the rear support 18 around the rotation axis, so that the rear end of the water receiving tray 19 rotates upward, thereby causing the lower end of the heat exchanger 15 to be inserted into the water receiving groove 193 of the water receiving tray 19 from the upper opening of the water receiving tray 19, as shown. Figure 20 As shown, the front end of the water receiving tray 19 is then continuously grasped to control the water receiving tray 19 to rotate counterclockwise relative to the rear support 18 around the rotation axis, so as to rotate the rear end of the water receiving tray 19 upward to the preset target position, as shown. Figure 19As shown, the water tray 19 is positioned upright on the rear support 18 to easily install the water trough 193. Then, the front panel 11 is installed on the front end of the rear support 18 to restore the air conditioner indoor unit 10. Since the water trough 193 has been thoroughly cleaned, the heat exchange performance of the air conditioner indoor unit 10 can be improved.

[0063] Compared to existing linear extraction methods, this embodiment allows for the independent rotation and disassembly of the water receiving tray 193 relative to the rear support 18 around a rotation axis. This reduces the operating space required for individual rotation and disassembly of the water receiving tray 193, enabling separate rotation and disassembly of the water tray 19 within a limited operating space. This makes it effectively applicable to wall-mounted, floor-standing, and window air conditioners, thus broadening its versatility. Furthermore, this design, where the water receiving tray 193 rotates and disassembles relative to the rear support 18 around a rotation axis, does not affect the structural strength of any component of the indoor unit 10, nor does it add unnecessary accessories, effectively ensuring the reliability of the indoor unit 10.

[0064] Therefore, in this embodiment, the indoor unit 10 of the air conditioner can be rotated and disassembled separately in a limited operating space, making the disassembly and assembly of the water tray 19 simple and convenient, and greatly reducing the cleaning difficulty of the water tray 19, thereby improving the cleaning effect of the water tray 19, and further improving the heat exchange performance, so as to improve the user experience.

[0065] Combination Figures 7 to 14 In this embodiment, the lower end face of the water receiving tray 19 is provided with a protruding first guide rib 195, and the lower inner side of the rear support 18 is provided with a recessed first guide groove 182. The first guide groove 182 extends circumferentially around the rotation axis, and the first guide rib 195 can be slidably inserted into the first guide groove 182. Alternatively, the lower end face of the water receiving tray 19 is provided with a recessed second guide groove, and the lower inner side of the rear support 18 is provided with a protruding second guide rib. The second guide rib extends circumferentially around the rotation axis, and the second guide groove can be slidably fitted onto the second guide rib. Thus, the matching arrangement of the guide rib and the guide groove guides and limits the rotation of the water receiving tray 19 relative to the rear support 18 around the rotation axis, making the assembly and disassembly of the water receiving tray 19 relative to the rear support 18 around the rotation axis stable and reliable. In a preferred embodiment, the first guide rib 195 or the second guide groove is located in the middle of the water receiving tray 19 in the left-right direction of the air conditioner indoor unit 10.

[0066] To further improve the stability and reliability of the water receiving tray 19 rotating and disassembling relative to the rear support 18 around the rotation axis, in this embodiment, the bottom end of the water receiving tray 19 is provided with a first sliding surface 196, and the inner side of the lower end of the rear support 18 is provided with a first arc surface 183. The first arc surface 183 extends circumferentially around the rotation axis, and the first sliding surface 196 can be adapted to slide and support on the first arc surface 183, thereby guiding the water receiving tray 19 to rotate smoothly and quickly around the rotation axis relative to the rear support 18.

[0067] To further improve the stability and reliability of the water receiving tray 19 rotating and disassembling relative to the rear support 18 around the rotation axis, in this embodiment, a second sliding surface 197 is provided at the bottom of the water receiving tray 19, and a second arc surface 184 is provided on the inner side of the lower end of the rear support 18. The second arc surface 184 extends circumferentially around the rotation axis and is located at the front or rear end of the first arc surface 183. The second distance radius between the second arc surface 184 and the rotation axis is different from the first distance radius between the first arc surface 183 and the rotation axis. The second sliding surface 197 can be adapted to slide and support on the second arc surface 184 to improve the stability and reliability of the front and rear ends of the water receiving tray 19 rotating relative to the rear support 18 around the rotation axis, so as to avoid the front or rear ends of the water receiving tray 19 shaking during the rotation and disassembly process. In a preferred embodiment, the second arc surface 184 is located at the rear end of the first arc surface 183, and the second distance radius between the second arc surface 184 and the rotation axis is smaller than the first distance radius between the first arc surface 183 and the rotation axis. This prevents the first arc surface 183 at the front end from being too high and blocking the rear end of the water receiving tray 19 from being pulled out during the clockwise rotation of the water receiving tray 19 relative to the rear support 18 around the rotation axis while guiding the rotation. This improves the convenience and speed of rotating and disassembling the water receiving tray 19 relative to the rear support 18 around the rotation axis.

[0068] To further improve the stability and reliability of the water tray 19 during rotation and disassembly relative to the rear support 18 around the rotation axis, in this embodiment, the first arc surface 183 is provided with first sliding grooves 185 at both ends in the left-right direction of the air conditioner indoor unit 10, and the first sliding surface 196 is provided with first slide rails 1961 at both ends in the left-right direction of the air conditioner indoor unit 10. The first sliding grooves 185 extend circumferentially around the rotation axis, and the first slide rails 1961 can be slidably inserted into the first sliding grooves 185; or, the first arc surface 183 is provided with second slide rails at both ends in the left-right direction of the air conditioner indoor unit 10, and the first sliding surface 196 is provided with second sliding grooves at both ends in the left-right direction of the air conditioner indoor unit 10. The second slide rails extend circumferentially around the rotation axis, and the second sliding grooves... The second slide plate 197 is provided with a third slide rail at both ends of the second arc surface 184 in the left-right direction of the air conditioner indoor unit 10, and the third slide rail is provided at both ends of the second slide surface 197 in the left-right direction of the air conditioner indoor unit 10. The third slide rail extends circumferentially around the rotation axis, and the third slide rail can be slidably inserted into the third slide rail. Alternatively, the second arc surface 184 is provided with a fourth slide rail at both ends of the second arc surface 184 in the left-right direction of the air conditioner indoor unit 10, and the second slide surface 197 is provided with a fourth slide rail at both ends of the second arc surface 197 in the left-right direction of the air conditioner indoor unit 10. The fourth slide rail extends circumferentially around the rotation axis, and the fourth slide rail can be slidably fitted onto the fourth slide rail, so that the water receiving tray 19 can be stably supported on the rear support 18.

[0069] To securely support the water tray 19 on the rear support 18, this embodiment provides a connecting plate 1912 for the water tray 19. The connecting plate 1912 has a through-hole 1913. A stud 186 is provided at the front end of the rear support 18. The screw of the fastener can be detachably passed through the connecting hole 1913 and connected to the stud 186, and the head of the fastener can press against the outer end face of the connecting plate 1912 away from the stud 186. Specifically, the fastener can be a screw, bolt, or other threaded fastener.

[0070] To facilitate the gripping of the water tray 19 and control its rotation relative to the rear support 18 for assembly and disassembly, the front end of the water tray 19 in this embodiment is provided with at least one gripping protrusion 191. Preferably, in this embodiment, there are two gripping protrusions 191, which are arranged side by side in the left-right direction of the indoor unit 10 of the air conditioner. This allows the user to grip the two gripping protrusions 191 on the water tray 19 with both hands, so as to conveniently and quickly control the rotation of the water tray 19 relative to the rear support 18 for assembly and disassembly.

[0071] Specifically, in this embodiment, the water receiving tank 193 includes a first guide channel 1931 and a second guide channel 1932 that are connected to each other. The first guide channel 1931 is located near the front end of the water receiving pan 19, and the second guide channel 1932 is located near the rear end of the water receiving pan 19. The bottom end of the second guide channel 1932 protrudes downward from the first guide channel 1931. The lower end of the heat exchanger 15 can be inserted into the first guide channel 1931. A drain nozzle 194 is provided on the bottom end face of the second guide channel 1932. Therefore, since the bottom of the second guide channel 1932 protrudes downward from the first guide channel 1931 in this embodiment, the second guide channel 1932 is deeper than the first guide channel 1931. This allows the first guide channel 1931, which is opposite to the heat exchanger 15, to collect the condensate generated by the heat exchanger 15 and quickly send it to the second guide channel 1932 for storage, so that it can be discharged from the drain nozzle 194. This avoids excessive condensate in the first guide channel 1931 from soaking the lower end of the heat exchanger 15, thereby improving the heat exchange performance of the heat exchanger 15.

[0072] Furthermore, in this embodiment, the bottom end face of the first guide channel 1931 is provided with a guide rib 19311.

The guide ring 162 is arranged in a closed loop around the ventilation hole 1611 and is connected to the air duct inlet of the fan 17. The circumferential wall of the flow ring 162 is curved and extended in an arc shape, so that the airflow entering the casing from the air inlet 113 can be accurately delivered to the heat exchanger 15. After heat exchange in the heat exchanger 15, the heat exchange airflow is evenly and smoothly gathered and pressurized in the flow ring 162 of the guide ring 16 and then sent into the air duct of the fan 17. The heat exchange airflow is then sent to the upper air outlet 112 and the lower air outlet 192 through the air duct of the fan 17 to be delivered into the room for heat exchange. The design of the flow ring 162 can reduce wind resistance and noise, thereby helping to reduce noise, and has a gathering and pressurizing effect, thereby improving heat exchange efficiency.

[0082] To further limit the positioning of the water tray 19 and improve its operational stability and reliability, in this embodiment, the water tray 19 is provided with a first slot 199, and the lower end of the mounting plate 161 is provided with a first protrusion 165.
