[0057] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the window air conditioner includes a housing 100 and an indoor centrifugal fan 200. A water inlet 110 is provided on the indoor side of the housing 100; the indoor centrifugal fan 200 is provided in the housing 100, and the indoor centrifugal fan 200 includes a volute 210, the volute 210 has an axial air inlet 211 and a radial air outlet 212, and a wind cavity 213 connected to the air inlet 211 and the air outlet 212 is provided in the volute 210, and the air outlet 212 is located above the air inlet 211 and below the air cavity 213. A water storage space 300 is provided, and the water storage space 300 is used to store water to be atomized, and a flow hole 2131 connecting the air cavity 213 and the water storage space 300 is opened at the bottom of the wind cavity 213, and the water inlet 110 is connected to the wind cavity 213, and the water inlet 110 is located above the flow hole 2131 to promote the water located at the water inlet 110 to flow into the bottom of the wind cavity 213 and flow through the flow hole 2131 to the water storage space 300.

[0058] Since the window air conditioner of this embodiment uses the volute 210 of the original indoor centrifugal fan 200 of the window air conditioner as the delivery pipeline of the water adding system, the water required for the humidification function is delivered to the water storage space 300 located below the volute 210. Furthermore, on the basis of the original window air conditioner, no additional components (such as water delivery pipelines, etc.) are added, and there is no need to improve the various components of the original window air conditioner (for example, reduce the air duct / air cavity 213), and the configuration of the water adding system is realized. Therefore, the window air conditioner of this embodiment can ensure the original small size advantage while configuring the water adding system, and effectively avoid the increase of production / renovation costs.

[0059] In addition, in this embodiment, if it is to be ensured that the window air conditioner as a whole can have the original volume while adding a water adding pipeline, the volume of each component inside the housing 100 can be reduced to make room for the installation of the water adding pipeline. Moreover, on the indoor side of the window air conditioner, most of the space inside the housing 100 is occupied by air supply channels such as the air duct and the air cavity 213. If the air duct and the air cavity 213 and other components are reduced, the air supply, cooling and heating performance of the window air conditioner will be reduced. Furthermore, the window air conditioner of this embodiment can effectively ensure the air supply, cooling and heating performance of the original window air conditioner while configuring the water adding system.

[0060] Reference Figure 4 and Figure 5 In this embodiment, in order to ensure the flow performance of the centrifugal fan and to ensure that the water in the air cavity 213 can flow smoothly into the water storage space 300, the flow hole 2131 can be set as small as possible. For example, the range of the passing area of ​​the flow hole 2131 can be set to 1 square centimeter to 4 square centimeters.

[0061] Furthermore, the shape of the flow hole 2131 can be set to be a long strip extending along the connection between the front side plate of the volute 210 and the volute tongue 218 plate, so as to further ensure the flow performance of the centrifugal fan and the smoothness of the water passing through the flow hole 2131.

[0062] In a modified embodiment, a through switch may be provided at the circulation hole 2131, and the through switch may be configured to be in an open state when water is added to the water storage space 300, and in a closed state when the window air conditioner is in a heating mode, a cooling mode, or a wind supply mode, so as to ensure the flow performance of the centrifugal fan and ensure that the water in the air cavity 213 can flow smoothly into the water storage space 300. Of course, the through area and shape of the circulation hole 2131 may not be limited at this time.

[0063] Reference Figure 3 The wind cavity 213 includes a water temporary storage cavity 2132 , which is located below the air inlet 211 , and is used to temporarily store water flowing into the wind cavity 213 from the water inlet 110 .

[0064] It is understandable that if the amount of water entering the air cavity 213 is too large and cannot enter the water storage space 300 through the flow hole 2131, the portion of the air cavity 213 located below the air inlet 211, that is, the water temporary storage cavity 2132, can provide a temporary storage space for the water, so that the water in the air cavity 213 / water temporary storage cavity 2132 gradually flows into the water storage space 300. Furthermore, the window air conditioner of this embodiment can complete the water addition normally, and realize the water addition process of the water storage space 300.

[0065] Reference Figure 3 In this embodiment, a water retaining ring 214 is arranged around the air inlet 211 and extends into the air cavity 213 .

[0066] It is understandable that, by setting the water retaining ring 214, it is possible to well prevent the water from flowing out / splashing out of the volute 210 from the air inlet 211 in the wind cavity 213 during the process of adding water from the water inlet 110 to the water storage space 300, thereby preventing the water from dirtying the floor of the indoor space and ensuring the user experience. Moreover, in the following embodiments, since the indoor heat exchanger 400 covers the front of the air inlet 211, it is further possible to prevent the water from flowing out / splashing out of the volute 210 from the air inlet 211 in the wind cavity 213 during the process of adding water from the water inlet 110 to the water storage space 300, thereby ensuring the user experience.

[0067] Further, the distance between the water retaining ring 214 and the fan 220 of the indoor centrifugal fan 200 can be set as small as possible to ensure that the centrifugal fan can operate normally and further ensure user experience. For example, the distance between the water retaining ring 214 and the fan 220 of the indoor centrifugal fan 200 can be set to 1.5 cm to 3 cm. Specifically, the distance between the water retaining ring 214 and the fan 220 of the indoor centrifugal fan 200 can be 1.5 cm, 2 cm, 2.5 cm, or 3 cm.

[0068] Reference Figure 2 and Figure 3 In this embodiment, the volute 210 can be composed of an upper half shell 215 and a lower half shell 216 that are buckled and connected to each other, so as to facilitate the installation of the fan 220.

[0069] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 In this embodiment, an air outlet portion 120 is disposed on the front side surface of the indoor side of the shell 100 , and an air outlet duct 130 is disposed in the shell 100 , and the air outlet duct 130 is connected between the air outlet portion 120 and the air outlet 212 .

[0070] It is understandable that by providing the air outlet duct 130 extending in the front-to-rear direction, the air outlet 212 and the air outlet portion 120 can be connected, so that the window air conditioner can complete normal operation of air supply, cooling, heating and other modes.

[0071] In addition, the air outlet portion 120 may be an air outlet grille, or may be a knock-out opening without a grille and without the function of filtering / splitting the airflow.

[0072] In this embodiment, a portion of the bottom of the air outlet duct 130 close to the water inlet 110 is higher than a portion close to the air cavity 213 to ensure that water at the water inlet 110 flows into the air cavity 213 .

[0073] In one implementation of the location of the water inlet 110 in this embodiment, the water inlet 110 can be opened upward at the top of the shell 100 (the inner wall of the top of the shell 100 can be the top wall of the air outlet duct 130), and the water inlet 110 is set corresponding to the air outlet 212.

[0074] It is understandable that the water inlet 110 can be directly opened above the air outlet 212. When water is to be added to the water storage space 300, the water can be directly poured into the water inlet 110. In addition, since the water inlet 110 is located at the top of the housing 100 of the window air conditioner, the user can easily add water thereto without bending over, and there will be no other components of the window air conditioner that hinder the user's pouring action, thereby ensuring the user's experience.

[0075] In this embodiment, a water adding cap can be provided on the water adding port 110, and the water adding cap is opened when water needs to be added to the water storage space 300, and in other cases, the water adding cap is covered on the water adding port 110. This ensures the performance of the window air conditioner in the air supply, cooling, and heating modes while adding water to the water storage space 300.

[0076] In another embodiment of the water inlet 110 of the present embodiment, the water inlet 110 can be provided on the left side or right side of the housing 100. Specifically, a water inlet connected to the air cavity 213 can be provided at any position of the volute 210 higher than the air inlet 211, and the water inlet 110 and the water inlet are connected through a pipe. For another example, the water inlet can be provided on the wall of the air outlet duct 130, and the water inlet 110 and the water inlet are connected.

[0077] In this embodiment, a water adding cap can be provided on the water adding port 110, and the water adding cap is opened when water needs to be added to the water storage space 300, and in other cases, the water adding cap is covered on the water adding port 110. This ensures the performance of the window air conditioner in the air supply, cooling, and heating modes while adding water to the water storage space 300.

[0078] Reference Figure 1 In this embodiment, a water adding tray 217 extending from the water adding tray 110 to the outside of the shell 100 is provided at the water adding tray 110 , and a water adding tank 2171 in the water adding tray 217 is connected to the water adding tray 110 .

[0079] It is understandable that, since the surface where the water inlet 110 is located is a vertical surface, it is relatively difficult for the user to pour water into the water inlet 110 so that the water flows into the wind cavity 213. Therefore, the water adding tray 217 can be provided to facilitate the user to add water to the water storage space 300, and in this process, the user can directly pour water into the water adding tank 2171, and the water can flow toward the water inlet 110 and into the wind cavity 213, so as to effectively avoid the user from pouring water onto the ground when adding water to the water storage space 300, thereby ensuring the user's use experience.

[0080] In this embodiment, a portion of the bottom of the water adding tank 2171 close to the water adding port 110 is lower than a portion away from the water adding port 110 , so as to ensure that the water in the water adding tank 2171 flows toward the water adding port 110 .

[0081] Reference Figure 1 and Figure 6 In another implementation of the location of the water inlet 110 in the present embodiment, the water inlet 110 is opened forward on the front side of the shell 100, and the water inlet 110 is connected to the air outlet 212 through the air outlet duct 130 to promote the water at the water inlet 110 to flow into the air cavity 213 through the air outlet duct 130.

[0082] It is understandable that by opening the water inlet 110 on the front side of the housing 100 facing forward, and the water inlet 110 is connected to the air outlet 212 through the air outlet duct 130, such a setting can not only realize the configuration of the air cavity 213 and the air outlet duct 130 as a water supply pipeline for adding water to the water storage space 300, but also realize the addition of water to the water storage space 300. At the same time, the water inlet 110 can also be used as a part of the air outlet 120 to supply air to the indoor space. In addition, the performance of the air supply, cooling and heating modes of the window air conditioner can be guaranteed without setting up a water inlet cover.

[0083] Furthermore, the water inlet 110 is located in the area where the air outlet 120 belongs, so there is no need to open an additional through hole, which simplifies the production process of the window air conditioner of this embodiment.

[0084] Reference Figure 1 and Figure 6 In this embodiment, a water adding tray 217 extending from the water adding tray 110 to the outside of the shell 100 is provided at the water adding tray 110 , and a water adding tank 2171 in the water adding tray 217 is connected to the water adding tray 110 .

[0085] It is understandable that, since the surface where the water inlet 110 is located is a vertical surface, it is relatively difficult for the user to pour water into the water inlet 110 so that the water flows into the wind cavity 213. Therefore, the water adding tray 217 can be provided to facilitate the user to add water to the water storage space 300, and in this process, the user can directly pour water into the water adding tank 2171, and the water can flow toward the water inlet 110 and into the wind cavity 213, so as to effectively avoid the user from pouring water onto the ground when adding water to the water storage space 300, thereby ensuring the user's use experience.

[0086] In this embodiment, a portion of the bottom of the water adding tank 2171 close to the water adding port 110 is lower than a portion away from the water adding port 110 , so as to ensure that the water in the water adding tank 2171 flows toward the water adding port 110 .

[0087] Reference Figure 1In this embodiment, an air inlet 140 is further provided on the indoor side of the housing 100. The air inlet 140 is connected to the air inlet 211. This realizes the construction of the entire air duct in the window air conditioner.

[0088] In addition, the air inlet portion 140 may be an air inlet grille, or may be a knock-out opening without a grille and without the function of filtering / splitting the airflow.

[0089] Reference Figure 1 , Figure 2 and Figure 6 In one implementation of the position of the air inlet 140 in the present embodiment, the air inlet 140 is further provided on the front side surface of the indoor side of the shell 100, that is, the air inlet 140 is provided on the front side surface of the indoor side of the shell 100; and the air inlet 211 is arranged forward corresponding to the air inlet 140, the volute tongue 218 of the volute 210 is located at the upper left of the air inlet 211, and the air outlet 212 and the water inlet 110 are located at the upper right of the air inlet 211.

[0090] It is understandable that, by arranging the air inlet 140 on the front side of the housing 100, arranging the air inlet 211 forwardly corresponding to the air inlet 140, and arranging the volute tongue 218 and the water inlet 110 respectively at the upper left and upper right of the air inlet 211, such an arrangement, when the user adds water to the water storage space 300, the water entering the water inlet 110 and the air outlet duct 130 may flow into the bottom of the air cavity 213 along the part of the side plate of the volute 210 located on the right side of the air inlet 211. This can further prevent the water from flowing out of the volute 210 from the air inlet 211 in the air cavity 213 during the process of adding water from the water inlet 110 to the water storage space 300, thereby ensuring the user experience.

[0091] In another implementation manner of the location of the air inlet 140 in the present embodiment, the air inlet 140 is disposed on the right side surface / right side surface of the indoor side of the housing 100 .

[0092] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the window air conditioner further includes an indoor heat exchanger 400 and a water receiving pan 500. The indoor heat exchanger 400 is disposed in the housing 100, and the indoor heat exchanger 400 is disposed between the air inlet 140 and the air inlet 211. The indoor heat exchanger 400 is used to perform heat exchange on the airflow flowing from the air inlet 140 to the air inlet 211; the water receiving pan 500 is connected to the bottom of the volute 210, and the water receiving pan 500 is located below the indoor heat exchanger 400. The water storage space 300 includes a water receiving tank 510 located on the water receiving pan 500, and the water receiving tank 510 is used to receive condensed water generated on the indoor heat exchanger 400.

[0093] It is understandable that the water storage space 300 may be a water receiving tank 510 in the water receiving tray 500. Furthermore, the window air conditioner of this embodiment may not be provided with an additional water storage space 300 to ensure the advantage of the small volume of the original window air conditioner. The condensed water generated by the indoor heat exchanger 400 is used to realize the humidification function of the indoor space, which has good water-saving performance.

[0094] In addition, the depth of the water receiving tank 510 can be greater than or equal to 9 mm, and the volume of the water receiving tank 510 can be 1 liter to 1.5 liters, and can be preferably set to 1.18 liters. To ensure that the water receiving tank 510 can receive / store more water. For example, the depth of the water receiving tank 510 is set to 9 mm, 10 mm, 15 mm, 20 mm, etc. Further, the water storage box 600 in the following embodiments can be set smaller to ensure the aesthetics and compactness of the window air conditioner.

[0095] The effective water storage volume of the water storage box 600 is 0.066L, and the effective water storage volume of the chassis is 1.18L. The total water storage volume for one filling is about 1.26L.

[0096] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the water receiving tray 500 and the volute 210 can be an integrated structure.

[0097] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10In this embodiment, the window air conditioner includes a water storage box 600. The top of the water storage box 600 is connected to the bottom of the water receiving tray 500 and the volute 210, and the water storage space 300 includes a water storage chamber 610 arranged in the water storage box 600, and the water storage chamber 610 has an inlet 611 at the top of the water storage box 600; and, a connecting port 520 is opened at the bottom of the water receiving tray 500 and the bottom of the volute 210, and the connecting port 520 is connected to the water receiving groove 510 and the flow hole 2131, and the inlet 611 is correspondingly connected to the inlet 611, so as to promote the connection between the water storage chamber 610 and the wind cavity 213 and the connection between the water storage chamber 610 and the water receiving groove 510.

[0098] It can be understood that the provision of the water storage box 600 increases the capacity of the water storage space 300, thereby ensuring the operation of the humidification function of the window air conditioner.

[0099] In one implementation of the water storage box 600 of this embodiment, the water storage box 600 can be set inside the housing 100. However, in this case, the internal space of the housing 100 has to be provided for the water storage box 600 again, which will increase the volume of the housing 100, or reduce the volume of the internal components of the original window air conditioner (for example, the air cavity 213 or the air duct, etc.). This will greatly reduce the basic performance of the window air conditioner and increase the production cost of the window air conditioner.

[0100] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig.10 In another implementation of the water storage box 600 of the present embodiment, a disassembly opening 150 is provided at the bottom of the shell 100 at a position corresponding to the communication opening 520 , and the top of the water storage box 600 is connected to the communication opening 520 through the disassembly opening 150 .

[0101] It should be understood that, since the water storage box 600 is disposed at the bottom and the water storage box 600 is installed on the communication port 520 through the disassembly port 150, the water storage box 600 is externally disposed outside the housing 100, so that the overall volume of the original window air conditioner remains unchanged, and the window air conditioner can have the advantage of a small volume. The water storage space 300 is also expanded, so that the humidification performance of the window air conditioner is guaranteed. At the same time, the increase in the production cost of the window air conditioner is effectively avoided.

[0102] In addition, the volume of the water storage chamber 610 can be 0.01 liter to 0.1 liter. To ensure that the water storage box 600 can also have a smaller volume, to ensure the aesthetics and compactness of the window air conditioner. Preferably, the volume of the water storage chamber 610 can be set to 0.08 liters. Furthermore, the volume of the water storage space 300 can be preferably set to 1.26 liters, to greatly ensure the humidification performance of the window air conditioner.

[0103] In some other embodiments, the water storage box 600, the water receiving tray 500 and the volute 210 may be an integrated structure.

[0104] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig.10 In this embodiment, the top of the water storage box 600 is detachably connected to the communication port 520 through the disassembly port 150. Then the user can conveniently disassemble the water storage box 600 to add water. At the same time, when the indoor environmental humidity is within a suitable value for a period of time, the water storage box 600 can be disassembled to ensure the overall aesthetics of the original window air conditioner. The above greatly ensures the user experience.

[0105] Furthermore, when the water storage box 600 is removed, a disassembly cover can be detachably provided on the connecting port 520 to ensure the normal use of the water receiving tray 500 and prevent condensed water from flowing onto the indoor floor during the operation of the air conditioner, thereby ensuring the user experience.

[0106] In addition, the detachable connection between the top of the water storage box 600 and the communication port 520 can be realized by setting a thread at their connection. For example, an external thread is set on the outer periphery of the top of the water storage box 600, and an internal thread is set on the inner wall of the communication port 520. The detachable connection between the top of the water storage box 600 and the communication port 520 can also be realized by setting a thread at the connection between the water storage box 600 and the housing 100; it can also be realized by setting a buckle or other structure at the connection between the water storage box 600 and the housing 100. For example, an external thread is set on the outer periphery of the water storage box 600, and an internal thread is set on the inner wall of the disassembly port 150. For another example, a plurality of hooks are evenly set on the outer periphery of the water storage box 600, and buckles are set at positions corresponding to the hooks around the disassembly port 150, and the hooks are engaged with / disengaged from the buckles to realize the detachable connection of the water storage box 600.

[0107] Reference Figure 7 In this embodiment, the window air conditioner includes an atomizer 700. The atomizer 700 is disposed in the water storage space 300 and is used to atomize the water in the water storage space 300.

[0108] In addition, the atomizer 700 can be a water-free and power-off single-head ultrasonic atomizer; it can also be an electric heating element, which atomizes the water in the water storage space 300 by heating to achieve humidification; it can also be an evaporative filter or filter element, which achieves humidification by cold evaporation.

[0109] In some embodiments, the atomizer 700 may be disposed in the water receiving tank 510 to directly atomize the water in the water receiving tank 510 .

[0110] Reference Figure 7 In this embodiment, the atomizer 700 can also be disposed in the water storage chamber 610, and the atomizer 700 can be used to atomize the water in the water storage chamber 610. The indoor centrifugal fan 200 is used to cause the airflow to carry the water mist generated in the water storage chamber 610 at the indoor heat exchanger 400 and / or the water receiving tank 510 to flow out of the housing 100 through the air outlet 120.

[0111] It is understandable that when the atomizer 700 is working, the indoor centrifugal fan 200 will cause the indoor air flow to enter the housing 100 from the air inlet 140, and cause it to flow through the indoor heat exchanger 400, the air inlet 211, the air cavity 213, the air outlet 212, the air outlet duct 130, the air outlet 120 in sequence, and finally flow out of the housing 100 (such as Figure 7 In addition, when the airflow flows through the indoor heat exchanger 400, negative pressure is generated in the water receiving tank 510 and / or the water storage chamber 610, and then the atomized water mist in the water storage chamber 610 flows through the inlet 611 and the connecting port 520 to the water receiving tank 510 and the indoor heat exchanger 400, and enters the indoor space along with the airflow to increase the humidity of the indoor space.

[0112] Reference Figure 6 , Figure 7 and Figure 8 In this embodiment, when the user adds water to the water storage space 300, the water flows from the water adding tank 2171, through the air outlet duct 130, the air cavity 213, the flow hole 2131, the inlet 611, and into the water storage cavity 610. Before the water storage cavity 610 is full of water, the condensed water in the water receiving tray 500 will flow into the water storage cavity 610 first. When the water in the water storage cavity 610 is full, if there is still water in the water adding tank 2171 flowing into the air cavity 213, the water will continue to be stored in the water receiving tray 500.

[0113] In this embodiment, the window air conditioner includes an indoor humidity sensor and a liquid level sensor. The indoor humidity sensor is disposed at the air inlet 140, and the indoor humidity sensor is connected to the atomizer 700, and the indoor humidity sensor is used to detect the relative humidity value of the environment in the indoor space where the window air conditioner works; the liquid level sensor is disposed in the water storage chamber 610, and the liquid level sensor is used to detect the water height value in the water storage chamber 610; and the atomizer 700 is started when the relative humidity value of the environment is less than a first preset value and the water height value is greater than or equal to the first preset value; the atomizer 700 stops working when the relative humidity value of the environment is greater than or equal to a second preset value or the water height value is less than the first preset value, wherein the second preset value is greater than the first preset value.

[0114] It should be noted that the first preset value ranges from 40% to 50%, and may be preferably 45%; the first preset value may be from 60% to 70%, and may be preferably 65%; the first predetermined value may be from 2.5 cm to 3.5 cm, and may be preferably 3 cm. This ensures the normal operation of the humidification function of the window air conditioner.

[0115] In this embodiment, the window air conditioner includes a buzzer connected to the liquid level sensor, and the buzzer is used to remind the user of the window air conditioner that the water level is too low; and the buzzer emits a warning sound when the water height value is less than a first predetermined value.

[0116] And, the intelligent humidification process of the window air conditioner can be:

[0117] The humidity sensor detects the relative humidity at the indoor air inlet 140. If the relative humidity value is less than 45%, the reed switch of the liquid level sensor detects whether there is water shortage in the water storage box 600. When the water volume in the water storage box 600 reaches the set liquid level (3 cm from the bottom of the water storage box 600), the magnetic ring of the liquid level sensor floats to close the reed switch, and the atomizer 700 starts to work. Through the high-frequency resonance of the atomizer sheet of the atomizer 700, the nearby water is broken into small particles of about 5 microns. The indoor centrifugal fan 200 starts to run. The fan 220 of the indoor centrifugal fan 200 rotates to generate negative pressure inside the volute 210, and the small particles are continuously blown into the room through the volute 210, which plays the role of moistening the air; with the operation of the humidification function of the window air conditioner, the humidity sensor detects that the relative humidity at the indoor air inlet 140 reaches 65%, and the atomizer 700 stops working. When the water level in the water storage box 600 is lower than the set water level (3 cm from the bottom of the water storage box 600), the magnetic ring falls away from the reed switch, the reed switch is disconnected, the atomizer 700 stops, and the buzzer alarms for water shortage. It is necessary to manually add water to the water storage space 300 at the water inlet 110. When the liquid level sensor detects that the water level is within the normal range, the atomizer 700 starts, and the indoor fan runs to blow the atomized water vapor to the indoor side to adjust the air humidity.

[0118] Reference Figure 1 In this embodiment, the window air conditioner includes an indoor display screen 800. The indoor display screen 800 is arranged on the indoor side of the housing 100, and the indoor display screen 800 is used to display the ambient temperature value and the ambient relative humidity value of the indoor space.

[0119] In addition, a set temperature viewing button 910 and a wind speed viewing button 920 may also be provided on the shell 100, and the indoor display screen 800 may be configured to display the current set temperature of the indoor space and the current wind speed of the window air conditioner when the set temperature viewing button 910 and the wind speed viewing button 920 are pressed; and the indoor display screen 800 may also be configured to redisplay the ambient temperature value and the ambient relative humidity value after the set temperature viewing button 910 and the wind speed viewing button 920 are pressed for a preset time period / after the indoor display screen 800 displays the current set temperature and the current wind speed of the window air conditioner for a preset time period, that is, on the display screen, the ambient temperature value and the ambient relative humidity value cover the current set temperature and the current wind speed of the window air conditioner.

[0120] It should be understood that the preset time can range from 5 seconds to 15 seconds, and can be preferably 10 seconds, so that the user can see the current set temperature and the current wind speed of the window air conditioner. In addition, the indoor display screen 800 can display the ambient temperature value and the ambient relative humidity value of the indoor space for a long time, so that the user can quickly and timely understand the ambient temperature value and the ambient relative humidity value of the indoor space.

[0121] In addition, the indoor display screen 800 can be detachably mounted on the housing 100, that is, the indoor display screen 800 and the window air conditioner can be connected via a wireless communication module. Furthermore, the user can carry / place the indoor display screen 800 at any location (e.g., on a desk or coffee table) so that the user can timely learn about the ambient temperature and relative humidity of the indoor space.
