[0065] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0066] In the present application, the air conditioner 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 to cool or heat the indoor space.

[0067] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas 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.

[0068] 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 low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling 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.

[0069] 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.

[0070] 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.

[0071] refer to Figure 1 , Figure 2 Specifically, the air conditioner indoor unit involved in the present application includes an outer shell 100, and the outer shell 100 is formed with an air inlet 101 for introducing external airflow and an air outlet 102 for outputting the airflow into the room.

[0072] An air inlet channel is formed between the air inlet 101 and the air outlet 102 . A heat exchanger 200 , a filter device 310 , and a wet film humidifier 320 are sequentially arranged in the air inlet channel along the flow direction of the airflow.

[0073] That is, the wet film humidifier 320 is located downstream of the heat exchanger 200 , and the filter device 310 is disposed between the heat exchanger 200 and the wet film humidifier 320 .

[0074] The filter device 310 is fixed in the air inlet passage through the support assembly 330. Specifically, a mounting position is formed on the support assembly 330, and the filter device 310 can be detached in the mounting position.

[0075] A filter device 310 is provided between the wet film humidifier 320 and the heat exchanger 200. The filter device 310 can filter the airflow input into the wet film humidifier 320, reduce the dust content in the airflow, increase the service life of the wet film humidifier 320, and ensure the air quality.

[0076] The filter device 310 can also play a certain role in blocking the condensed water formed on the surface of the heat exchanger 200. The condensed water adheres to the filter device 310 and flows downward into the water receiving tray 500 along with the filter device 310, which is convenient for discharge, thus avoiding the problem of water accumulation inside the air conditioner. In addition, the filter device 310 is easy and quick to disassemble, and the cleaning cost is low.

[0077] refer to Figure 5-Figure 9 The support assembly 330 includes an upper support member 331 , a lower support member 332 and a side support member 333 . There are two side support members 333 , which are respectively disposed between the upper support member 331 and the lower support member 332 .

[0078] The upper support member 331 , the lower support member 332 and the side support member 333 are arranged to form a frame structure, and the filter device 310 is installed in the support assembly 330 .

[0079] In order to facilitate the positioning of the filter device 310 , an upper guide rail portion 3312 is provided at the bottom of the upper support member 331 , and a lower guide rail portion 3321 is formed on the lower support member 332 .

[0080] The installation position is formed between the upper rail portion 3312 and the lower rail portion 3321 , that is, the filter device 310 is installed between the upper rail portion 3312 and the lower rail portion 3321 .

[0081] The upper guide rail portion 3312 and the lower guide rail portion 3321 extend in a direction perpendicular to the side support member 333. In other words, the upper guide rail portion 3312 and the lower guide rail portion 3321 are arranged along the width direction of the filter device 310 to make the filter surface of the filter device 310 perpendicular to the air inlet channel to improve the filtering effect.

[0082] The upper guide rail portion 3312 and the lower guide rail portion 3321 are respectively formed with guide grooves arranged opposite to each other. Specifically, the upper guide rail portion 3312 and the lower guide rail portion 3321 are both channel steel structures.

[0083] The upper part and the lower part of the filter device 310 extend into the guide groove respectively, and the filter device 310 is limited in the front and rear directions through the guide grooves on the upper guide rail part 3312 and the lower guide rail part 3321 .

[0084] In addition to limiting the installation of the filter device 310, the upper guide rail portion 3312 and the lower guide rail portion 3321 also play a guiding role in the loading and unloading process.

[0085] The filter device 310 specifically includes a filter bracket and a filter screen fixed on the filter bracket. The filter bracket is a frame structure, and the upper and lower ends of the filter bracket move along the upper guide rail portion 3312 and the lower guide rail portion 3321 respectively.

[0086] An installation opening 3331 is formed on the side support member 333. The installation opening 3331 is a cut formed along the height direction of the side support member 333. The position of the installation opening 3331 is adapted to the position of the installation position. The filter device 310 is installed into the support assembly 330 from the installation opening 3331 or removed from the installation opening 3331.

[0087] The size of the installation opening 3331 is not less than the projection size of the filter device 310 on the side support member 333 to ensure that the filter device 310 can be smoothly installed and removed from the installation opening 3331 .

[0088] The installation opening 3331 is detachably connected to a cover portion 333. After the filter device 310 is installed into the support assembly 330, the cover portion 333 is fixed to the installation opening 3331 to block the installation opening 3331. At the same time, the filter device 310 is also fixed in the installation position to prevent it from escaping from the installation opening 3331.

[0089] In some embodiments of the present application, the wet film humidifier 320 is also fixed in the support assembly 330 to save installation costs and improve installation efficiency.

[0090] A water tank 340 is disposed on the upper support member 331 for storing and conveying humidification water into the wet film humidifier 320 .

[0091] The water tank member 340 is fixed on the upper surface of the upper support member 331 , and a water outlet hole 3311 communicating with the water tank member 340 is formed on the upper support member 331 .

[0092] The water outlet hole 3311 is located directly above the wet film humidifier 320 , so that the water output from the water tank 340 is transported to the wet film humidifier 320 through the water outlet hole 3311 .

[0093] In order to improve the uniformity of water delivery from the water tank 340 to the wet film humidifier 320 , a plurality of water outlet holes 3311 are designed.

[0094] The water outlet holes 3311 are arranged in an array on the upper support member 331 , and the water outlet holes 3311 are evenly distributed directly above the wet film humidifier 320 . The water in the water tank member 340 is evenly transported to the wet film humidifier 320 through each water outlet hole 3311 to increase the water content of the airflow passing through the wet film humidifier 320 .

[0095] Furthermore, the water tank member 340 is also configured to be flat, and the size of the water tank member 340 is also adapted to the maximum size of the matrix formed by the water outlet holes 3311 to ensure that the water output of each water outlet hole 3311 is consistent.

[0096] Water inlet branches 341 are respectively connected to both sides of the water tank component 340, and the two water inlet branches 341 are both connected to the water supply pipe 342. Water is input from the water supply pipe 342 and transported from both ends of the water tank component 340 to the water storage cavity of the water tank component 340 through the water inlet branches 341 at both ends, thereby improving the uniformity of water inflow into the water tank component 340.

[0097] In addition, the number of water inlet branch pipes 341 can be set to more than two, and the water inlet branch pipes 341 are symmetrically arranged on both sides of the water tank 340 as much as possible to avoid the problem of too large difference in the amount of water delivered to the wet film humidifier 320, such as more water on one side and less water on the other side.

[0098] The water inlet branch pipe 341 and the water supply pipe 342 are both connected to the upper support member 331. Specifically, an upper connecting outer edge extending upward is formed on the peripheral side of the upper support member 331, and support holes are formed at both ends of the upper connecting outer edge. The water inlet branch pipe 341 passes through the support hole. A support hole is also formed on one side of the upper support member 331, and the water supply pipe 342 passes through the support hole to provide support for the water supply pipe 342 and the water inlet branch pipe 341.

[0099] The upper support member 331 , the lower support member 332 and the side support member 333 are connected and fixed by welding or mechanical connection.

[0100] In some embodiments of the present application, a lower connecting outer edge is formed on the peripheral side of the lower support member 332, and the upper and lower ends of the side support member 333 are respectively fixed on the upper connecting outer edge and the lower connecting outer edge.

[0101] Specifically, refer to Figure 8 At least two lower fixing holes 3322 are provided at the position where the lower connecting outer edge is connected to the side support member 333, and upper fixing holes 3313 are formed at intervals at the position where the upper connecting outer edge is connected to the side support member 333. Connecting holes 3332 are respectively formed at the upper and lower ends of the side support member 333, and the connecting holes 3332 are respectively connected and fixed to the corresponding upper fixing holes 3313 or lower fixing holes 3322.

[0102] In order to prevent the side support member 333 from interfering with the water inlet branch pipe 341 , an avoidance portion 3333 is formed on the side support member 333 in advance. The avoidance portion 3333 is specifically a through hole structure, or the avoidance portion 3333 is a notch formed at the upper end of the side support member 333 .

[0103] Combination Fig.10 An inspection port 140 is provided on the side wall of the outer shell 100 , and an inspection cover plate is detachably connected to the inspection port 140 . The height of the inspection port 140 is not less than the height of the filter device 310 .

[0104] A fan component 400 is further provided downstream of the wet film humidifier 320 . The fan component 400 is located on a side close to the air outlet 102 . When the fan component 400 is turned on, it drives the airflow to be transported in a direction from the air inlet 101 to the air outlet 102 .

[0105] The heat exchanger 200 and the support assembly 330 are fixed above the water receiving tray 500 through the base 120. The water receiving tray 500 is connected to a drain pipe for draining the accumulated water in the water receiving tray 500.

[0106] The water receiving tray 500 is fixed on the bottom plate 110 of the outer shell 100. A water collecting tank is formed in the water receiving tray 500 for temporarily storing water dripping from the heat exchanger 200, the filter device 310 or the wet film humidifier 320. The drain pipe is connected to the lowest position of the water collecting tank so as to completely drain the accumulated water in the water receiving tray 500.

[0107] Specifically, there are at least two bases 120 , and the bases 120 are spaced apart from each other, and each base 120 extends in a direction from the water inlet to the water outlet.

[0108] The heat exchanger 200 and the support assembly 330 are arranged perpendicular to the base 120 , and the bottoms are supported on different bases 120 respectively.

[0109] refer to Figure 3 , Figure 4 The fan base 410 at the bottom of the fan member 400 is fixed to the bottom of the air inlet channel through the support 130 , and a buffer portion 131 is further provided between the support 130 and the fan member 400 .

[0110] The buffer part 131 is made of rubber material and is used to reduce the transmission of vibration generated during the operation of the fan component 400 to the outside and reduce noise.

[0111] After the fan component 400 is started, the airflow enters the air inlet channel from the air inlet 101, passes through the heat exchanger 200, and filters the dust inside through the filter device 310 before entering the wet film humidifier 320 for humidification. The water in the water tank component 340 is evenly transported to the wet film humidifier 320 through the water outlet hole 3311. By controlling the water supply speed in the water tank component 340, the water content of the airflow after passing through the wet film humidifier 320 can be controlled.

[0112] The filter device 310 has low installation cost and is easy to clean. Pressure detection components are respectively set at the air inlet and outlet ends of the filter device 310, which can detect the wind pressure value before and after the filter device 310 in real time, and then obtain the wind pressure difference before and after the filter device 310 to determine whether the filter device 310 is blocked and needs to be cleaned.

[0113] The blocking state of the filter device 310 can be displayed through a display panel or the like to facilitate user observation.

[0114] When the front-rear wind pressure difference of the filter device 310 is less than the preset value, it indicates that the filter device 310 works normally.

[0115] When the front and rear wind pressure difference of the filter device 310 is not less than the preset value, it means that the filter device 310 is clogged by dust or the like, and the user needs to be prompted to clean it.

[0116] When cleaning, the inspection cover corresponding to the position of the filter device 310 is opened, the side support member 333 of the support assembly 330 is exposed, and the operator or user removes the cover part 333 and can directly pull the filter device 310 out from the installation port 3331.

[0117] After cleaning is completed, the filter device 310 is inserted into the installation position from the installation opening 3331 , and the sealing portion 333 and the inspection cover are fixed in sequence.

[0118] The present application also proposes a combined air conditioning unit, which includes an outer shell 100, a heat exchanger 200 and a wet film humidifier 320. An air inlet 101 and an air outlet 102 are formed on the outer shell 100, and an air inlet channel is arranged between the air inlet 101 and the air outlet 102.

[0119] The heat exchanger 200 and the wet film humidifier 320 are sequentially arranged in the air inlet passage along the flow direction of the air flow.

[0120] A filter device 310 is further provided between the heat exchanger 200 and the wet film humidifier 320 . The filter device 310 is configured such that after the airflow passes through the heat exchanger 200 for heat exchange, it is filtered by the filter device 310 and then transported to the wet film humidifier 320 .

[0121] The specific configuration of the filter device 310 can be achieved in the following ways:
