Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a window air conditioner. Background Technology

[0002] Most window air conditioners on the market are square in shape and are integrated units, consisting of a chassis, casing, panel, air duct, indoor fan, outdoor fan, motor, compressor, condenser, evaporator, etc. After installation, the height of the sun blockage is approximately the total height of the window air conditioner, preventing customers from enjoying sufficient sunlight. Because the outdoor and indoor parts of a window air conditioner are a single unit, noise generated by the outdoor part will also be transmitted into the room, resulting in very loud noise and affecting customer comfort, making it unsuitable for customers who are sensitive to noise.

[0003] To address this issue, the saddle-type air conditioner was developed. It mainly consists of an indoor unit and an outdoor unit, separating the indoor and outdoor environments to effectively reduce indoor noise. The indoor and outdoor units are connected by a saddle-type structure. The indoor unit mainly includes a panel, casing, chassis, indoor heat exchanger, cross-flow fan, motor, air duct, and electrical control components. The outdoor unit mainly includes a casing, chassis, compressor, outdoor heat exchanger, piping, motor, motor bracket, and axial fan.

[0004] For indoor units, simplifying structural components to facilitate installation and reduce size is a key challenge that needs continuous optimization and improvement for saddle-type air conditioners, which will help enhance the product's market competitiveness.

[0131] This embodiment discloses a saddle-shaped air conditioner, referring to... Figure 1 It includes an indoor unit 100 located on the indoor side, an outdoor unit 200 located on the outdoor side, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200.

[0132] The saddle-type air conditioner has an N-type structure, with the indoor unit 100 and the outdoor unit 200 located at both ends of the saddle structure 300 and on the same side of the saddle structure 300.

[0133] When the saddle-type air conditioner is installed on the window, the saddle structure 300 sits directly on the window, the indoor unit 100 is located on the indoor side, and the outdoor unit 200 is located on the outdoor side.

[0134] Since both the indoor unit 100 and the outdoor unit 200 are located below the window, this saddle-shaped air conditioner solves the problem of existing integrated window units blocking sunlight after installation.

[0135] By separating the indoor unit 100 from the outdoor unit 200 through the saddle bridge structure 300, it is helpful to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side, thereby improving user comfort.

[0136] The indoor unit 100 mainly includes components such as the casing, indoor heat exchanger 120, water tray 400, cross-flow fan 130, and air duct.

[0137] The outdoor unit 200 mainly includes components such as the casing, outdoor heat exchanger 230, axial fan 250, and compressor 220.

[0138] [Indoor unit - Indoor side air intake and exhaust]

[0139] In some embodiments of this application, there is a certain gap between the back panel of the indoor unit 100 and the indoor side wall.

[0140] In some embodiments of this application, the air intake and exhaust method of the indoor unit 100 is as follows: (Refer to...) Figure 2 The indoor unit 100 has air intake on the front and back sides and air outlet at the top.

[0141] Specifically, the indoor unit 100 has an indoor front air inlet 112 on the front panel, an indoor rear air inlet 113 on the rear panel, and an indoor top air outlet 111 on the top.

[0142] Indoor air flows into the inner cavity of the indoor unit 100 from the indoor front air inlet 112 and the indoor rear air inlet 113. After heat exchange by the indoor heat exchanger 120, it flows out from the indoor top air outlet 111.

[0143] The gap between the rear panel of the indoor unit 100 and the indoor side wall makes it possible for the indoor unit 100 to have rear-side air intake.

[0144] The indoor unit 100 draws air from both the front and rear sides simultaneously, significantly increasing the air intake compared to existing window units. This helps improve the heat exchange efficiency of the indoor heat exchanger, thereby enhancing the overall heat exchange efficiency of the unit.

[0145] The simultaneous air intake from the front and rear sides ensures sufficient airflow while eliminating bottom air intake, thus solving the problems of increased air resistance in the drip tray and condensate overflow and dripping caused by bottom air intake of the indoor unit in existing technologies.

[0146] Since there is no need to open an air inlet at the bottom of the indoor unit, there is no need to leave too much space between the bottom plate of the indoor unit and the water tray, which helps to reduce the overall height of the indoor unit and reduce the space occupied indoors.

[0147] The indoor unit has a hollowed-out air inlet on the back panel, which, combined with a corresponding concave design, helps to reduce the weight of the indoor unit and also helps to improve the structural strength of the back panel.

[0148] In some embodiments of this application, removable filters are provided at the indoor front air inlet 112 and the indoor rear air inlet 113 to filter dust and impurities.

[0149] In some embodiments of this application, the indoor ceiling air outlet 111 is tilted towards the indoor side, which facilitates the flow of heat-exchanged gas towards the indoor side.

[0150] In some embodiments of this application, a pad or adjustable bolt (not shown) is provided between the back panel of the indoor unit 100 and the indoor side wall to improve the installation stability of the indoor unit 100.

[0151] [Indoor Unit - Indoor Heat Exchanger]

[0152] In some embodiments of this application, reference is made to Figure 15 and Figure 16 The indoor heat exchanger 120 has a three-section structure, including heat exchanger section 121, heat exchanger section 122 and heat exchanger section 123 connected in sequence.

[0153] Heat exchanger section 121 extends vertically, heat exchanger section 122 extends diagonally downward from the bottom of heat exchanger section 121, and heat exchanger section 123 extends diagonally upward from the bottom of heat exchanger section 122.

[0154] The first heat exchanger 121 and the second heat exchanger 122 are located near the front panel of the indoor unit 100, and the second heat exchanger 122 extends obliquely downward from the bottom of the first heat exchanger 121 in a direction away from the front panel.

[0155] The heat exchanger section 123 is located near the rear panel of the indoor unit 100, and extends obliquely upward from the bottom of the heat exchanger section 122 towards the rear panel.

[0156] The front air inlet flows through heat exchanger section 121 and heat exchanger section 122, while the rear air inlet flows through heat exchanger section 123.

[0157] The cross-flow fan 130 is located within the area enclosed by the three-section indoor heat exchanger, making full use of the internal space of the indoor unit 100, resulting in a compact structure.

[0158] After being heated by heat exchangers 121, 122 and 123, the air is collected and flows out from the top air outlet 111.

[0159] The air intakes on the front and rear sides of the indoor unit are perfectly matched with the three-section indoor heat exchanger, allowing each air intake to fully exchange heat with the indoor heat exchanger, greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0160] In some embodiments of this application, the indoor rear air inlet 113 is arranged directly opposite the heat exchanger section 123, so that the gas flowing in from the indoor rear air inlet can directly exchange heat with the heat exchanger section 123, thereby improving the heat exchange efficiency.

[0161] In some embodiments of this application, the angles between the first section 121, the second section 122, and the third section 123 of the heat exchanger and the vertical direction are all less than 40°, ensuring that the indoor heat exchanger 120 drains smoothly after installation, and that the condensate can flow down the fins, preventing the condensate from dripping from the middle of the fins.

[0162] In some embodiments of this application, the top of the three-section heat exchanger 123 is not higher than the connection position between the first-section heat exchanger 121 and the second-section heat exchanger 122. While meeting the heat exchange requirements and the installation requirements of the cross-flow fan, this makes the overall structure of the indoor heat exchanger 120 more compact and helps to reduce the size of the indoor unit 100.

[0163] In some embodiments of this application, the length of the second section 122 of the heat exchanger is greater than the lengths of the first section 121 and the third section 123 of the heat exchanger, respectively. In the limited internal cavity of the indoor unit 100, the effective area of ​​the air intake and the indoor heat exchanger 120 is maximized to improve the heat exchange efficiency.

[0165] In some embodiments disclosed in this application, reference is made to Figure 15 , Figures 21 to 24 The indoor unit has an air duct frame 900 inside its cavity, which includes a main frame 910 and a volute assembly 920.

[0166] The main frame 910 is located near the rear panel of the indoor unit 100, specifically near the vertical part 3112 of the L-shaped base plate of the indoor saddle housing. The volute assembly 920 is located on the top front side of the main frame 910, forming an air outlet between the main frame 910 and the main frame 910.

[0167] The indoor heat exchanger 120 is located on the front side of the main frame 910 and below the volute tongue assembly 920. A cross-flow fan 130 is installed in the area enclosed by the indoor heat exchanger 120 and the main frame 910.

[0168] Under the action of the cross-flow fan 130, the indoor air enters the room and flows into the area enclosed by the main frame 910 and the indoor heat exchanger 120 after heat exchange, and then flows out through the top air outlet 111.

[0169] The duct frame 900 in this application is a detachable structure, which facilitates production and installation and enables the realization of a small indoor unit size.

[0170] The duct frame 900 not only ensures convenient installation and provides support, but also serves as the duct housing to guarantee airflow. The duct frame 900 is designed with ventilation openings 913 to allow air intake, which can be combined with the rear-side air intake of the indoor unit. The frame has multiple uses and can replace the functions of various structural components, saving space and reducing costs.

[0171] In some embodiments of this application, reference is made to Figure 26 The main frame 910 includes a vertical part 912 and an arc-shaped part 911 with an integral structure. The vertical part 912 is located at the lower part of the arc-shaped part 911, and an air outlet is formed between the volute assembly 920 and the arc-shaped part 911.

[0172] Refer to Figure 22 A cross-flow fan 130 is installed in the area enclosed by the arc-shaped portion 911 and the indoor heat exchanger 120, and the arc-shaped portion 911 provides space for the installation of the cross-flow fan 130.

[0173] The vertical part 912 is provided with a vent 913, which is directly connected to the rear air inlet 113 of the indoor unit to allow air to flow in from the back of the indoor unit.

[0174] The back side of the arc-shaped section 911 is equipped with an insulation component (not shown) to improve the insulation performance of the air duct.

[0175] In some embodiments of this application, reference is made to Figure 22 , Figures 27 to 29 The volute assembly 920 includes a volute strip 921 and a volute strip support 922, both of which are detachable structures, facilitating production and assembly.

[0176] The worm tongue support 922 includes a worm tongue support body 9221 and connecting parts 9222 located at both ends of the worm tongue support body 9221. The connecting parts 9222 are connected to the main frame 910. The worm tongue 921 is located on the side of the worm tongue support body 9221 facing the main frame 910.

[0177] In some embodiments of this application, the volute tongue support body 9221 includes a base plate 92211 located on the top side and a first flap 92212 disposed on the base plate 92211. The first flap 92212 extends downward from the base plate 92211 and extends obliquely downward from the base plate 92211 in a direction away from the main frame 910.

[0178] The volute tongue 921 includes a volute tongue part 9211 and a volute tongue part 9212 with an integral structure. The two are V-shaped and the included angle between them is acute. The volute tongue part 9211 is connected to the substrate 92211 and the volute tongue part 9212 is connected to the first flap 92212, thereby mounting the volute tongue 921 onto the volute tongue bracket 922.

[0179] During assembly, first install the volute tongue 921 onto the volute tongue bracket 922, and then install the volute tongue bracket 922 onto the main frame 910, thus completing the assembly of the air duct frame 900.

[0180] In some embodiments of this application, a first abutment plate 92121 and a second abutment plate 9212 are provided on the side of the volute tongue strip 2 portion 9212 facing the volute tongue strip support 922. The first abutment plate 92121 extends along the length direction of the volute tongue strip 2 portion 9212, and the second abutment plate 92122 extends along the height direction of the volute tongue strip 2 portion 9212. Multiple second abutment plates 92122 are spaced apart along the length direction of the volute tongue strip 2 portion 9212.

[0181] The first abutment plate 92121 has a plurality of limiting portions 92124 spaced apart along its length direction on its side, and the limiting portions 92124 and the second abutment plate 92122 define a limiting groove 92123 between them along the length direction of the first abutment plate 92121.

[0182] The lower end of the first flap 92212 is inserted into the limiting groove 92123 and abuts against the first abutting plate 92121. The side of the first flap 92212 abuts against the second abutting plate 92122, thus realizing the assembly between the bottom of the worm tongue 921 and the worm tongue bracket 922.

[0183] The assembly between the worm tongue strip part 9211 and the worm tongue strip bracket 922, and the assembly between the first flange 92212 and the limiting groove 92123, can limit the displacement of the worm tongue strip 921 in the vertical and horizontal directions. Furthermore, the abutment between the second abutment plate 92122 and the first flange 92212 further improves the assembly stability of the worm tongue strip 921 and prevents the worm tongue strip 921 from shaking and making noise when the air is vented.

[0184] In some embodiments of this application, the substrate 92211 is further provided with a second flap 92213 and a third flap 92214. The second flap 92213 and the third flap 92214 extend obliquely downward from the substrate 92211 and in a direction away from the main frame 910. The third flap 92214 is located outside the second flap 92213, and the second flap 92213 is located outside the first flap 92212. The bottom end of the third flap 92214 is lower than the bottom end of the second flap 92213.

[0185] The top of the indoor heat exchanger 120 (specifically the top of the heat exchanger section 121) is close to the second flap 92213 and located inside the third flap 92214, so as to avoid gaps between the top of the indoor heat exchanger 120 and the volute assembly 920, so that all the air intake at the front of the indoor unit can pass through the indoor heat exchanger 120 for heat exchange.

[0186] In some embodiments of this application, the substrate 92211 is provided with a plurality of snap-fit ​​protrusions 92215 along its length direction, and correspondingly, a portion of the volute tongue 9211 is provided with a plurality of snap-fit ​​slots 92111 along its length direction. The snap-fit ​​slots 92111 engage with the corresponding snap-fit ​​protrusions 92215 to realize the installation between the top of the volute tongue 921 and the volute tongue bracket 922.

[0187] During installation, first insert the first flap 92212 into the limiting groove 92123 at the bottom of the worm tongue 921, and then snap the top of the worm tongue 921 into the worm tongue bracket 922 to complete the installation.

[0188] [Installation of Indoor Unit - Air Duct Frame]

[0189] In some embodiments of this application, reference is made to Figure 32 The air duct frame 900 is connected to the saddle housing 330. In this case, the vertical part of the indoor saddle housing 310 constitutes the rear panel of the indoor unit. The saddle housing 330 has an L-shaped structure, with its horizontal part connected to the outdoor saddle housing 320 and its vertical part connected to the indoor unit. Figure 15 It can be seen that the vertical part of the saddle cover 330 constitutes part of the side wall of the indoor unit's casing, and the air duct frame 900 is connected to the saddle cover 330.

[0190] The top of the duct frame 900 (specifically the top of the main frame 910) is connected to one end of the horizontal part of the saddle cover 330; a water receiving tray 400 is provided in the inner cavity of the indoor unit, and the bottom of the duct frame 900 (specifically the bottom of the main frame 910) sits on the water receiving tray 400, thus improving the installation stability of the duct frame 900.

[0191] In some embodiments of this application, the water receiving tray 400 is provided with a support structure for installing the indoor heat exchanger 120, and the air duct frame 900 is also connected to the support structure to further improve the installation stability of the air duct frame 900.

[0192] The installation of the air duct frame 900 in this application makes full use of the existing structure in the indoor unit, achieving the effect of easy installation and a compact and stable structure.

[0193] [Indoor unit - rear side filter]

[0194] In some embodiments of this application, reference is made to Figure 33 and Figure 35 A filter screen 930 is provided between the rear air inlet 113 and the ventilation opening 913 on the air duct frame 900 to filter the air intake from the back side of the indoor unit 100.

[0195] The filter 930 can be inserted through the side of the indoor unit 100 casing into the gap between the back panel of the indoor unit and the air duct frame 900 (specifically the vertical part 912 of the main frame), or pulled out from the gap between the back panel of the indoor unit 100 and the air duct frame 900, making it easy to remove and maintain the filter 930.

[0196] In some embodiments of this application, see also Figure 35 The filter 930 is slidably mounted on the main frame 910. Specifically, the vertical part 912 of the main frame is provided with a slide rail structure. The side of the casing of the indoor unit 100 is provided with an opening 334. The filter 930 is slidably mounted on the slide rail structure. The filter 930 can enter and exit through the opening 334, realizing the sliding installation of the filter 930 and making it easy to pull out.

[0197] In some embodiments of this application, a limiting structure 915 is provided on the vertical part 912 of the main frame to limit the horizontal sliding displacement of the filter screen 930. The limiting structure 915 is a limiting frame structure.

[0198] The slide structure is located on the side closer to the opening 334, and the limiting structure 915 is located on the side farther away from the opening 334. When the filter screen 930 is inserted through the opening 334, it is first guided by the slide structure, and the insertion movement is relatively smooth and reliable. When the end of the filter screen 930 abuts against the limiting structure 915, it is inserted into place.

[0199] In some embodiments of this application, the slide structure includes an upper slide 9141 and a lower slide 9142. The upper part of the filter screen 930 is disposed in the upper slide 9141 and the lower part is disposed in the lower slide 9142, with sliding on both the upper and lower sides, thereby improving the reliability of sliding.

[0200] In some embodiments of this application, reference is made to Figures 36 to 38 The filter screen 930 has a stop plate 931 at one end. The stop plate 931 has a first insertion part 932 and a first snap-fit ​​part 933. The stop plate 931 abuts against the side of the casing of the indoor unit 100 to limit the insertion displacement of the filter screen 930.

[0201] The indoor unit 100 has a second plug-in part 335 and a second snap-fit ​​part 336 on the side of the casing near the opening 334.

[0202] The first insertion part 932 is inserted into the second insertion part 335, and the first snap-fit ​​part 933 is snap-fitted into the second snap-fit ​​part 336 to achieve the fixed installation of the filter screen 930.

[0203] In one specific embodiment, the first insertion part 932 is an insert, and the second insertion part 335 is a socket; the first snap-fit ​​part 933 and the second snap-fit ​​part 336 are both snap-fit ​​structures, and the two snap-fit ​​with each other.

[0204] In some embodiments of this application, the vertical portion of the saddle cover 330 forms part of the casing sidewall of the indoor unit, and the vertical portion of the saddle cover 330 is provided with an opening 334 for the filter screen 930 to enter and exit.

[0205] In some embodiments of this application, the heat exchanger three sections 122 are directly opposite the vent 913, which can cover the vent 913 so that the air intake on the back side can be heat exchanged.

[0206] [Indoor Unit - Indoor Heat Exchanger Installation]

[0207] In some embodiments of this application, reference is made to Figures 39 to 41 The support structure for fixing the indoor heat exchanger 120 includes a first support part 171 and a second support part 172. The first support part 171 is used to install one end of the indoor heat exchanger 120, which sits on the water receiving pan 400 and is fixedly connected to the water receiving pan 400 and the main frame 910. The second support part 172 is used to install the other end of the indoor heat exchanger 120, which sits on the water receiving pan 400 and is fixedly connected to the water receiving pan 400, thus realizing the fixed installation of the indoor heat exchanger 120.

[0208] The indoor heat exchanger 120 is fixedly installed in the indoor unit through the air duct frame 900, water receiving tray 400, first support part 171 and second support part 172. The components are compact and easy to disassemble and assemble.

[0209] In some embodiments of this application, reference is made to Figure 26 The main frame 910 has a first mounting part 9161 on one side and a second mounting part 9162 on the other side.

[0210] Reference Figures 30 to 32 The first support part 171 is fixedly connected to the first mounting part 9161, and the two are joined to form a mounting hole. The mounting hole is provided with a bearing seat 131 for mounting the cross-flow fan 130. The second mounting part 9162 is provided with a motor cover 132, and a mounting cavity is formed between the second mounting part 9162 and the motor cover 132. The mounting cavity is provided with a motor 133 for driving the cross-flow fan 130. The second support part 172 is also fixedly connected to the motor cover 132, thus realizing the fixed installation of the cross-flow fan 130.

[0211] The first support part 171 and the second support part 172 not only fix the indoor heat exchanger 120, but also serve to install the cross-flow fan 130. The fixation between the support structure and the water receiving tray 400 helps to further improve the stability of the air duct frame 900 and the indoor heat exchanger 120.

[0212] In some embodiments of this application, reference is made to Figure 30 The front part of the first support part 171 is fixedly connected to the water receiving tray 400 at a1 by screws, and the upper part of the first support part 171 is fixedly connected to the first mounting part 9161 at a2 and a3 by screws; see reference Figure 31 and Figure 41 The second support part 172 includes a support base 1722 and a tube sheet 1721. The front part of the support base 1722 is fixedly connected to the water receiving pan 400 at b1 by screws. The tube sheet 1721 is fixedly installed at the end of the indoor heat exchanger 120. The tube sheet 1721 is fixedly connected to the support base 1722 at b2 and b3, and fixedly connected to the motor cover 132 at b4.

[0213] By setting fixed connection points for each component in appropriate locations, the number of connection points is not large, which simplifies installation and ensures good structural stability.

[0214] [Indoor unit - drip tray]

[0215] In some embodiments of this application, the indoor unit 100 is provided with a drip tray 400 for holding condensate in its inner cavity.

[0216] Reference Figure 17 The water receiving tray 400 is provided with a water receiving area 410 and a water holding area 420. The water holding area 420 is provided with an inner water tank 422 and an outer water tank 421 arranged inside and outside. A filter part 500 is provided at the position where the inner water tank 422 and the outer water tank 421 are connected. The water receiving area 410 is connected to the outer water tank 421. The inner water tank 422 is connected to the drain pump 700 through the drain pipe 710.

[0217] The condensate produced by the indoor heat exchanger 120 first drips into the water receiving area 410, and then flows into the inner water tank 422 through the outer water tank 421 and the filter section 500.

[0218] The external water tank 421 mainly serves to settle larger dust particles and dirt in the condensate.

[0219] Because the outer water tank 421 has a large water storage area, the water level rises slowly during the condensate storage process. Therefore, the dust particles and dirt in the condensate have enough time to settle to the bottom of the outer water tank on their own.

[0220] After initial sedimentation treatment in the outer water tank 421, the condensate passes through the filter section 500 for secondary treatment of the fine dust particles contained in the condensate, thus isolating the fine dust within the outer water tank 421.

[0221] After secondary treatment, the condensate enters the inner water tank 422. At this point, the condensate has reached a high level of cleanliness, which can effectively prevent impurities from clogging the drainage pipes and the drainage pump when it is pumped by the drainage pump 700.

[0222] The inner water tank 422 is equipped with a float switch (not shown). When the water level in the inner water tank 422 reaches a certain height, the float switch is activated, and the drain pump 700 starts to pump water.

[0223] In this embodiment, the water receiving tray 400 adopts the method of "outer water tank sedimentation and inner water tank filtration", which effectively improves the removal effect of dust and dirt in condensate water, reduces the blockage of drainage pipes and drainage pumps, and reduces drainage pump maintenance costs.

[0224] After the machine has been used for a period of time, the user can remove the water plug structure on the outer water tank 421. The water in the outer water tank 421, driven by gravity, carries the previously deposited mud, sand, dust particles and other debris out from the water plug location, thus achieving a self-cleaning effect.

[0225] In some embodiments of this application, the total area of ​​the water-holding area 420 (outer water tank 421 + inner water tank 422) accounts for about 1 / 6 of the total area of ​​the water receiving tray 400, and the water-holding volume is larger, which can hold more condensate.

[0226] The inner water tank 422 has an area of ​​approximately half that of the entire water-holding area 420, allowing it to hold more clean condensate.

[0227] In some embodiments of this application, a water tank cover (not shown) is provided on the top of the water-holding area 420 to prevent condensate containing dust particles and dirt dripping from the indoor heat exchanger 120 from falling into the water-holding area 420.

[0228] In some embodiments of this application, reference continues to be made to... Figure 17 The inner water tank 422 is located on one side of the outer water tank 421 near the corner. A water flow channel for the condensate in the outer water tank is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421. The filter part 500 is located at one end of the water flow channel.

[0229] Water in the outer water tank 421 flows along the water flow channel to the filter section 500, and after filtration, it flows into the inner water tank 422.

[0230] The water flow channel increases the flow distance and time of condensate in the outer water tank 421, which helps to improve the settling effect of dust particles and dirt.

[0231] In some embodiments of this application, combined with Figure 18 and Figure 19 The water-holding area 420 is located on one side of the water receiving tray 400 near the corner, and one end of the water flow channel extends to the side wall of the water receiving tray 400.

[0232] The water receiving tray 400 has a first water inlet 423 on its side wall and a second water inlet 424 on its side wall. The first water inlet 423 and the second water inlet 424 are directly opposite each other. A detachable sealing part 430 is provided at the first water inlet 423.

[0233] The condensate in the outer water tank 421 is filtered by the filter section 500 and then flows into the inner water tank 422 through the second water inlet 424.

[0234] After the machine has been running for a period of time, the user can remove the sealing part 430 himself, and the condensate in the outer water tank 421 can be discharged through the first water inlet 423 to completely remove the dust particles and dirt that have settled in the outer water tank 421.

[0235] Remove the filter section 500, and the condensate in the inner water tank 422 can be discharged through the second water inlet 424 and the first water inlet 423.

[0236] In other words, after the machine has been running for a period of time, the sealing part 430 and the filter part 500 can be removed, and all the water in the outer water tank 421 and the inner water tank 422 can be drained.

[0237] The first water inlet 423 is located at one end of the outer water tank 421, and the second water inlet 424 is located at one end of the inner water tank 422. When draining, the condensate in the water tank flows from one end to the other, which also plays a certain role in rinsing the inner wall of the water tank.

[0238] In some embodiments of this application, one end of the filter section 500 is disposed in the first water inlet 423, thereby sealing the first water inlet 423; the other end of the filter section 500 is disposed in the second water inlet 424, thereby connecting the outer water tank 421 and the inner water tank 422 through the inner cavity of the filter section 500.

[0239] As the condensate in the outer water tank 421 flows from the inner cavity of the filter section 500 to the inner water tank 422, it automatically completes the secondary filtration of dust particles.

[0240] The filter unit 500 can be removed from the outside of the water receiving tray 400, making it easy to clean and replace the filter unit 500.

[0241] In some embodiments of this application, the side wall of the water receiving tray 400 is provided with a mounting post 440, and the mounting post 400 is provided with a through hole communicating with the outer water tank 421. One end of the filter part 500 (i.e. the extension part 518) extends into the through hole through the first water inlet 423.

[0242] The mounting post 440 is detachably provided with a sealing part 430 on its outer side to seal the through hole. Specifically, the outer periphery of the mounting post 440 is provided with external threads, and the sealing part 430 is a plug structure with internal threads on its inner periphery. The sealing part 430 is screwed onto the mounting post 440.

[0243] When the filter section 500 needs to be disassembled, first remove the sealing part 430, then pull the extension part 518 by hand to pull out the filter section 500.

[0244] In some embodiments of this application, the sidewall of the outer water tank 421 includes a first outer sidewall 4211, a second outer sidewall 4212, a third outer sidewall 4213, and a fourth outer sidewall 4214 connected in sequence.

[0245] The sidewalls in the inner water tank 422 that form the water flow channel include a first inner sidewall 4221, a second inner sidewall 4222, a third inner sidewall 4223 and a fourth inner sidewall 4224 connected in sequence, and each pair of adjacent sidewalls has an L-shaped structure.

[0246] The first inner wall 4221 is connected to the fourth outer wall 4211, the fourth inner wall 4224 is connected to the third outer wall 4213, and there is a gap between the third inner wall 4223 and the third outer wall 4213 for accommodating the filter section 500.

[0247] The first water inlet 423 is located on the third outer side wall 4213, and the second water inlet 424 is located on the third inner side wall 4223.

[0248] The structure of the water-holding area 420 is designed in this way, so that the water flow channel formed between the outer water tank 421 and the inner water tank 421 is L-shaped. The long and narrow water flow channel is more conducive to the settling of dust particles and dirt.

[0249] The filter unit 500 is located at the corner where the outer water tank 421 and the inner water tank 422 connect. The water flow is buffered at this corner, which helps to improve the secondary filtration effect of dust particles.

[0250] In some embodiments of this application, multiple water-guiding ribs are provided in the water receiving area 410 to guide the flow of condensate.

[0251] In some embodiments of this application, the side of the outer water tank 421 is provided with a plurality of spaced water-dividing ribs at a position communicating with the water receiving area 410. A water flow gap is formed between two adjacent water-dividing ribs to supply water into the outer water tank 421, which plays a role in equalizing the flow of condensate.

[0252] Since the indoor unit in this case eliminates the bottom air intake, the chassis 160 of the indoor unit is a closed structure. In some embodiments of this application, refer to... Figures 42 to 44 The water receiving tray 400 is connected to the chassis 160, forming a sealed space between the water receiving tray 400 and the chassis 160. The air in the sealed space has a low thermal conductivity, which can reduce the heat transfer between the water receiving tray 400 and the chassis 160. The temperature of the water receiving tray 400 will not affect the temperature of the chassis 160, effectively preventing condensation from forming on the chassis 160.

[0253] In some embodiments of this application, heat insulation material may be filled between the water receiving tray 400 and the chassis 160 to further reduce heat transfer between the water receiving tray 400 and the chassis 160.

[0254] In some embodiments of this application, reference continues to be made to... Figures 42 to 44 The chassis 160 includes a chassis body 161. The chassis body 161 has upwardly extending flanges 162 around its perimeter. The flanges 162 are fixedly connected to the circumferential sidewall of the water receiving tray 400 by screws. The flanges 162 wrap around and fix the water receiving tray 400, forming a sealed space between the water receiving tray 400 and the chassis body 161.

[0255] In some embodiments of this application, a support structure is provided between the water receiving tray 400 and the chassis body 161 to improve the installation stability of the water receiving tray 400.

[0256] The bottom of the water receiving tray 400 is provided with multiple spaced support parts 461. The support parts 461 are cross-shaped column structures. The support parts 461 abut against the chassis body 161. While improving the installation stability between the water receiving tray 400 and the chassis 160, it also helps to improve the structural strength of the water receiving tray 400.

[0257] A connecting rib 462 is provided between two adjacent support parts 461 to further improve the structural strength of the water receiving tray 400.

[0258] [Indoor unit - Drain tray surface structure]

[0259] To improve the water-conducting performance of the water-receiving area 410, in some embodiments of this application, reference is made to... Figure 44 and45 , combined Figure 17 The indicated directions Figure 44 This is a schematic diagram showing a section cut at x1 along the width direction of the water receiving tray 400. Figure 45 The diagram shows a section cut at x2 along the length of the water receiving tray 400. The upper surface of the water receiving area 410 is composed of a first inclined surface 412 and a second inclined surface 413. The first inclined surface 412 and the second inclined surface 413 guide the condensate on the upper surface of the water receiving area 410 to the water holding area 420 from different directions, so that the water on the water receiving area 410 can flow smoothly into the water holding area 420 and avoid water accumulation on the water receiving area 410.

[0260] Two inclined surfaces guide the water in the water-receiving area 410 from different directions. This can improve the guiding efficiency and avoid the water accumulation problem that is common in the single inclined surface guiding method in the prior art.

[0261] The first inclined surface 412 and the second inclined surface 413 guide the condensate on the upper surface of the water receiving area 410 to the outer water tank 421. The water in the outer water tank 421 flows into the inner water tank 422 through the filter section 500. The condensate in the inner water tank 422 is discharged to the outdoor unit side through the drain pipe 710.

[0262] In some embodiments of this application, the water-holding area 420 is located on one side of the water receiving tray 400, specifically at the rear corner of the water receiving tray 400, so as to facilitate connection with the drainage pipe 710 led from the outdoor unit side.

[0263] The first inclined surface 412 slopes downward from the side of the water receiving tray 400 toward the intersection of the first inclined surface 412 and the second inclined surface 413, and also slopes downward toward the water-holding area 420; the second inclined surface 413 slopes downward from the side of the water receiving tray 400 toward the intersection of the first inclined surface 412 and the second inclined surface 413, and also slopes downward toward the water-holding area 420.

[0264] For ease of understanding, Figure 17 The dashed line 'r' represents the intersection of the first inclined surface 412 and the second inclined surface 413, combined with... Figure 44 and Figure 45 The first inclined surface 412 is connected to the front and right sides of the water receiving tray 400, and the second inclined surface 413 is connected to the rear and left sides of the water receiving tray 400. Both the first inclined surface 412 and the second inclined surface 413 are inclined downwards towards the water-holding area 420, and they are also inclined downwards relative to each other. That is, there is a certain angle between the first inclined surface 412 and the second inclined surface 413, so that there are no dead corners for water accumulation in the water receiving area 410.

[0265] In some embodiments of this application, reference is made to Figure 17 The intersection line r of the first inclined surface 412 and the second inclined surface 413 extends from the end angle r1 of the water receiving tray 400 that is diagonally opposite to the water holding area 420 to the end angle r2 of the water holding area 420. This connects the front of the water holding area 420 with the first inclined surface 412 and the left side of the water holding area 420 with the second inclined surface 413, which helps to further improve the water conduction performance.

[0266] In some embodiments of this application, multiple water distribution holes are provided at the locations where the first inclined surface 412 and the second inclined surface 413 communicate with the water-holding area 420, so as to play a role in equalizing the flow of the converging water.
