[0002] Currently, air conditioning products on the market include auxiliary functions in addition to heat exchange, such as humidification and purification. These auxiliary functions are usually integrated with the heat exchange function, which makes the air conditioner's position in the room relatively fixed. The auxiliary functions and heat exchange function of the air conditioner cannot be separated and used independently, resulting in users not being able to adjust and use the various functions of the air conditioner according to their own needs, thus reducing the applicability of the air conditioner.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

When the sub-unit is located inside the receiving cavity of the main unit, the main unit has a heat exchange function. The second air outlet of the sub-unit is connected to the first air outlet of the main unit. At this time, the air handling module of the sub-unit can work, enabling the sub-unit to process indoor air, such as humidifying and purifying indoor air. That is, when the sub-unit is inside the main unit, the sub-unit can work in coordination with the main unit. When the sub-unit is located outside the first outer casing of the main unit, the sub-unit is separated from the main unit and is not connected to the main unit.

For example, the sub-unit can humidify and purify air in different rooms. That is, after the sub-unit is separated from the main unit, both the sub-unit and the main unit can work independently. Therefore, it can be seen that the main unit and the slave unit of this application can work together when they are together, and when the slave unit is separated from the main unit, both the main unit and the slave unit can work independently, so that users can adjust and use various functions of the wall-mounted air conditioner indoor unit according to their own needs, thus improving the applicability of the wall-mounted air conditioner indoor unit.

[0053] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0055] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0057] This invention provides a wall-mounted air conditioner indoor unit and an air conditioner including the wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit can solve the problem that the multiple functions of existing air conditioners cannot be separated, which makes it impossible for users to adjust and use the multiple functions of the air conditioner according to their own needs, resulting in low applicability of the air conditioner.

[0058] Please see Figures 1 to 5 In one embodiment of the wall-mounted air conditioner indoor unit of the present invention, the wall-mounted air conditioner indoor unit includes a main unit 100 and a sub-unit 200. The main unit 100 includes a first outer shell 110 and an indoor heat exchange module disposed within the first outer shell 110. The first outer shell 110 has a receiving cavity 111 and a first air outlet 102 communicating with the receiving cavity 111. The sub-unit 200 includes a second outer shell 210 and an air handling module 220 disposed within the second outer shell 210. The second outer shell 210 is provided with a second air outlet 202 corresponding to the first air outlet 102. The sub-unit 200 has a retracted state and a detached state. The air handling module 220 can operate in both the retracted state and the detached state. In the retracted state, the sub-unit 200 is located within the receiving cavity 111, and the first air outlet 102 communicates with the second air outlet 202. In the detached state, the sub-unit 200 is located outside the first outer shell 110.

[0059] It is understood that the indoor unit of a wall-mounted air conditioner can be cylindrical, elliptical, square, or other shapes, depending on actual usage requirements; no specific limitations are imposed here. The main unit 100 can extend vertically, and both the main unit 100 and the daughter unit 200 can have equal or variable cross-sections in the vertical direction. The shapes of the main unit 100 and the daughter unit 200 can be the same or different.

[0060] The indoor heat exchange module has a heat exchange duct, and the air handling module 220 has an indoor air handling duct 221. When the sub-unit 200 is in the retracted state, the heat exchange duct and the indoor air handling duct 221 can be isolated from each other, or they can be connected to each other. Specifically, in this embodiment, when the sub-unit 200 is in the retracted state, the heat exchange duct and the indoor air handling duct 221 can be isolated from each other, so that the heat exchange duct and the indoor air handling duct 221 are independent and do not affect each other. Whether the sub-unit 200 is located inside the main unit 100 or separated from the main unit 100, it will not affect the heat exchange effect of the indoor heat exchange module, thus ensuring the heat exchange stability of the wall-mounted air conditioner indoor unit.

[0061] The indoor heat exchange module is used to exchange heat with the airflow passing through the heat exchange duct to achieve cooling or heating functions. The indoor heat exchange module may only have cooling functions, or it may have both cooling and heating functions simultaneously. The air handling module 220 is used to process the airflow passing through the indoor air handling duct 221, for example, by humidifying and / or purifying the airflow to achieve humidifying and / or purifying the indoor air. The first housing 110 is provided with an air inlet, which can be connected to the heat exchange duct, or to the indoor air handling duct 221, or simultaneously to both.

[0062] When the air inlet is connected to the heat exchange duct, the air inlet is a heat exchange air inlet 105. The first outer casing 110 is provided with a heat exchange air inlet 105 and a heat exchange air outlet 106 connected to the heat exchange duct. The heat exchange duct is provided with a heat exchange component, which includes a heat exchanger and a heat exchange fan 225. The heat exchange fan 225 drives the airflow from the heat exchange air inlet 105 into the heat exchange duct, and after heat exchange by the heat exchanger, it is blown out from the heat exchange air outlet 106, thereby realizing indoor cooling or heating. The indoor heat exchange module also includes refrigerant pipes, compressors, and other structures. The specific structure can refer to the existing technology of wall-mounted air conditioner indoor units, and will not be described in detail here. Specifically, in this embodiment, the first outer casing 110 includes multiple side plates, a first bottom plate 112, and a first top plate. The multiple side plates are installed on the first bottom plate 112, and the first top plate covers the multiple side plates. The multiple side plates, the first bottom plate 112, and the first top plate enclose to form a cavity structure. The heat exchange air inlet 105 is located on one side plate of the first outer shell 110, and the heat exchange air outlet 106 is located on the other side plate of the first outer shell 110. This arrangement allows the airflow to exit from the side of the first outer shell 110 after passing through the indoor heat exchange module of the mother unit 100. That is, in this embodiment, the hot or cold air of the mother unit 100 is exited from the side of the first outer shell 110.

[0063] When the air inlet is connected to the indoor air handling duct 221, the air inlet is the indoor air inlet 101. The first outer casing 110 is provided with an indoor air inlet 101 and a first air outlet 102 connected to the indoor air handling duct 221. Indoor air can enter from the indoor air inlet 101, pass through the indoor air handling duct 221 of the sub-unit 200, and then be discharged from the second air outlet 202, and then discharged from the first air outlet 102 on the first outer casing 110. In this way, when the sub-unit 200 is inside the main unit 100, the sub-unit 200 can process the indoor air to achieve functions such as air supply, humidification, and purification. It is understood that the heat exchange air inlet 105 and the indoor air inlet 101 mentioned above can be set independently, or they can be integrated together. The specific settings can be configured according to needs and are not limited here.

[0064] Furthermore, the first outer casing 110 has an internal receiving cavity 111. When the slave unit 200 is in the retracted state, it can be installed in the receiving cavity 111, which can be located at the upper, middle, or lower part of the first outer casing 110. When the slave unit 200 is in the detached state, it is not connected to the main unit 100 and can be moved to any location indoors to work independently. This includes the main unit 100 and the slave unit 200 working separately in the same room, and the slave unit 200 being moved to a different room from the main unit 100. For example, the main unit 100 can be installed in the first bedroom, and the slave unit 200 can be moved to the second bedroom to work independently. The main unit 100 has a heat exchange function, while the slave unit 200 has functions such as air supply, humidification, and purification. By moving the slave unit 200, the user's needs for different functions in different spaces can be met. Compared to existing air conditioners where multiple functions cannot be separated and moved, the main unit 100 and the sub-unit 200 of this application can work together, and the main unit 100 and the sub-unit 200 can be separated and work independently. The sub-unit 200 can deliver air, humidify and purify indoor air in the user's designated area, thereby meeting the different usage needs of users and improving the applicability of the wall-mounted air conditioner indoor unit.

[0065] Furthermore, the number of sub-units 200 can be one, two, or more. Multiple sub-units 200 can be arranged vertically or horizontally. In this case, the mother unit 100 can be equipped with only one heat exchange duct and heat exchange component, or it can be equipped with two or more sets of heat exchange ducts and heat exchange components.

[0066] The air handling module 220 includes at least one of the following: an air supply component 222, a purification component 223, a humidification component 224, a dehumidification component, a sterilization component, and an aromatherapy component. The air supply component 222 can specifically be a fan 225, which drives airflow through a fan wheel to achieve the air supply function of the sub-unit 200. The air supply component 222 may also include an electric heating element, which enables the sub-unit 200 to deliver hot air. The purification component 223 may include HEPA filters, filters for gaseous pollutants such as formaldehyde, TVOC, and toluene, a water-washing purification module, an electrostatic dust removal module, etc., which are not listed here. The purification component 223 enables the sub-unit 200 to purify the air, thereby meeting the user's needs for dust removal and air purification. The humidification component 224 can specifically be a wet film assembly, etc. The dehumidification component may specifically include a condenser and an evaporator; the condenser achieves dehumidification, and the evaporator provides heating to achieve overall constant temperature dehumidification. By incorporating humidification and dehumidification components 224, the sub-unit 200 possesses both humidification and dehumidification functions, thereby meeting users' requirements for air humidity. The sterilization component may specifically include an ultraviolet sterilization module, a negative ion sterilization module, etc., enabling the sub-unit 200 to perform sterilization, suitable for environments with high levels of bacteria and viruses, thus meeting users' needs for air sterilization and disinfection. The aromatherapy component may specifically include an ultrasonic oscillation device, which nano-atomizes water molecules and plant essential oils to add fragrance to the room and eliminate odors. The air handling module 220 can be configured with different functions and components depending on usage requirements; the specific combinations are not listed here. When the sub-units 200 are in a separate state, the main unit 100 can operate, and the air handling modules 220 can also operate independently, allowing the sub-units 200 to have different functions. When there are two or more sub-units 200, the functions of the air handling modules 220 in each sub-unit 200 can be the same or different.

[0067] The wall-mounted air conditioner indoor unit of this application includes a main unit 100 and a sub-unit 200. The first outer casing 110 of the main unit 100 has a receiving cavity 111 and a first air outlet 102 communicating with the receiving cavity 111. The sub-unit 200 includes a second outer casing 210 and an air handling module 220 disposed within the second outer casing 210. The second outer casing 210 is provided with a second air outlet 202 corresponding to the first air outlet 102. When the sub-unit 200 is located within the receiving cavity of the main unit 100, the main unit 100 has a heat exchange function, and the second air outlet 202 of the sub-unit 200 communicates with the first air outlet 102 of the main unit 100. At this time, the air handling module 220 of the sub-unit 200 can work, enabling the sub-unit 200 to circulate the indoor air. The air handling unit 220 can process air, such as humidifying and purifying indoor air. When the slave unit 200 is inside the mother unit 100, it can work in coordination with the mother unit 100. When the slave unit 200 is located outside the first outer casing 110 of the mother unit 100, the slave unit 200 is separated from the mother unit 100 and is not connected to the mother unit 100. At this time, the heat exchange function of the mother unit 100 can be used, and the air handling module 220 of the slave unit 200 can also work. The slave unit 200 can process air anywhere in the room, such as humidifying and purifying air in different rooms. That is, after the slave unit 200 is separated from the mother unit 100, both the slave unit 200 and the mother unit 100 can work independently. Therefore, it can be seen that the mother unit 100 and the daughter unit 200 of this application can work together when they are together. After the daughter unit 200 is separated from the mother unit 100, both the mother unit 100 and the daughter unit 200 can work independently, so that users can adjust and use various functions of the wall-mounted air conditioner indoor unit according to their own needs, thus improving the applicability of the wall-mounted air conditioner indoor unit.

[0068] Please see Figure 5 , Figure 6 and Figure 8 In one embodiment, the first outer casing 110 includes a first base plate 112, and the first air outlet 102 is disposed on the first base plate 112. The second outer casing 210 includes a second base plate 211, and the second air outlet 202 is disposed on the second base plate 211 and is correspondingly disposed to the first air outlet 102.

[0069] It is understandable that the air handling module 220 of the sub-unit 200 has an indoor air handling duct 221, and the second air outlet 202 is correspondingly set with the first air outlet 102. When the sub-unit 200 is in the storage state, the airflow passes through the indoor air handling duct 221 of the sub-unit 200 and is discharged from the second air outlet 202, and then passes through the first air outlet 102 to be discharged to the outside of the first outer casing 110. Since the first air outlet 102 is located on the first base plate 112 and the second air outlet 202 is located on the second base plate 211, when the sub-unit 200 is installed inside the mother unit 100, the airflow passing through the sub-unit 200 is discharged downwards from the first outer casing 110.

[0070] As mentioned above, after the airflow passes through the indoor heat exchange module of the main unit 100, it can be discharged from the side of the first outer casing 110. That is, the hot or cold air of the main unit 100 is discharged to the side of the first outer casing 110. Combined with the fact that the airflow passing through the daughter unit 200 in this embodiment is discharged downwards from the first outer casing 110, the airflow direction of the heat exchange air of the main unit 100 and the airflow direction of the daughter unit 200 do not affect each other. This is beneficial to improving the airflow stability of the heat exchange air of the main unit 100 and the airflow stability of the daughter unit 200, thereby improving the reliability of the wall-mounted air conditioner indoor unit.

[0071] Please see Figure 2 , Figure 4 and Figure 8 In one embodiment, the first outer shell 110 extends in the vertical direction, the receiving cavity 111 is located at the lower part of the first outer shell 110, the lower part of the side plate of the first outer shell 110 is provided with an indoor air inlet 101, and the air handling module 220 has an indoor air handling duct 221 that connects the indoor air inlet 101 and the second air outlet 202.

[0072] It is understood that the first outer shell 110 in this embodiment is columnar, and the receiving cavity 111 is located at the lower part of the first outer shell 110. This facilitates the installation and removal of the sub-machine 200, and avoids the situation where the user needs to climb to install it when the receiving cavity 111 is located in the middle or upper part of the first outer shell 110, thereby improving the convenience of installing the sub-machine 200.

[0073] The indoor air inlet 101 is located at the lower part of the first outer casing 110. When the sub-unit 200 is installed in the receiving cavity 111, the indoor air inlet 101 is close to the indoor air handling duct 221 of the sub-unit 200. The airflow entering from the indoor air inlet 101 can quickly enter the indoor air handling duct 221. The compact arrangement of the indoor air inlet 101 and the sub-unit 200 helps to reduce the loss caused by the gap between the first outer casing 110 and the sub-unit 200, thereby improving the smoothness of the airflow through the sub-unit 200 and reducing the volume of the first outer casing 110.

[0074] Please see Figures 2 to 4 as well as Figure 10 In one embodiment, the second outer casing 210 of the sub-unit 200 is provided with a sub-unit air inlet 201 communicating with the indoor air handling duct 221. A first damper 280 is provided between the sub-unit air inlet 201 and the indoor air inlet 101. The first damper 280 is closably disposed within the receiving cavity 111 and is used to open or close the indoor air inlet 101 to connect or disconnect the indoor air inlet 101 from the sub-unit air inlet 201. When the first damper 280 is open, the airflow entering from the indoor air inlet 101 of the first outer casing 110 can enter the indoor air handling duct 221 through the sub-unit air inlet 201 and be discharged from the second air outlet 202. When the first damper 280 is closed, the indoor air inlet 101 is closed, and the airflow outside the indoor air inlet 101 cannot enter the indoor air handling duct 221 through the indoor air inlet 101.

[0075] It is understood that the first damper 280 can open or close the sub-unit air inlet 201 in various ways, such as, but not limited to, opening the sub-unit air inlet 201 by rotation or sliding, and is not specifically limited here. The first damper 280 is driven by a driving component, which includes, but is not limited to, a rotary motor, a rotary cylinder, a motor and gear rack assembly, a push-pull rod, or a linkage mechanism, etc., and is not specifically limited here.

[0076] Please see Figure 3 , Figure 4 and Figure 6 In one embodiment, the first outer shell 110 is further provided with a fresh air inlet 103, and the second outer shell 210 and the mother unit enclose a fresh air cavity 212 that communicates with the fresh air inlet 103. The fresh air inlet 103 communicates with the outdoor air through a fresh air duct 120. The second outer shell 210 is provided with a slave unit air inlet 201 that communicates with the indoor air handling duct 221. The fresh air cavity 212 is provided with a fresh air outlet 213 that communicates with the fresh air inlet 103 and the slave unit air inlet 201. The fresh air outlet 213 is used to introduce outdoor fresh air into the indoor air handling duct 221.

[0077] It is understood that one end of the fresh air duct 120 is located at the fresh air inlet 103, and the other end is located outdoors, so that outdoor fresh air can enter the fresh air inlet 103 and the fresh air chamber 212 along the fresh air duct 120. The airflow entering the fresh air chamber 212 can be introduced through the fresh air outlet 213 and enter the indoor air handling duct 221 from the unit inlet 201, and then discharged from the second outlet 202 of the second casing 210. In this way, the wall-mounted air conditioner indoor unit has the function of introducing outdoor fresh air. It can be seen that the wall-mounted air conditioner indoor unit of this embodiment also has a fresh air function, thus improving the applicability of the wall-mounted air conditioner indoor unit.

[0078] Please see Figure 3 and Figure 4 In one embodiment, the sub-unit 200 further includes a second air damper 290, which is openably and closably disposed at the fresh air inlet 213. The second air damper 290 is used to open or close the fresh air inlet 213. When the second damper 290 opens the fresh air inlet 213, the first damper 280 closes. Outdoor fresh air can pass through the fresh air inlet 103, the fresh air inlet 213, and the sub-unit air inlet 201 in sequence before entering the indoor air handling duct 221. Then, it passes through the second air outlet 202 and the first air outlet 102 in sequence before being discharged to the outside of the first casing 110. When the second damper 290 closes the fresh air inlet 213, outdoor fresh air cannot enter the sub-unit 200. At this time, the first damper 280 can be opened so that the indoor airflow can pass through the indoor air inlet 101 and the sub-unit air inlet 201 in sequence before entering the indoor air handling duct 221, thereby realizing the function of the sub-unit 200 in handling indoor air. The process of the sub-unit 200 in handling indoor air is described above and will not be repeated here.

[0079] It is understood that the second damper 290 can open or close the fresh air inlet 213 in various ways, such as, but not limited to, opening the fresh air inlet 213 by rotation or sliding, and the specific method is not limited here. The second damper 290 is driven by a driving component, which includes, but is not limited to, a rotary motor, a rotary cylinder, a motor and gear rack assembly, a push-pull rod, or a linkage mechanism, etc., and the specific method is not limited here.

[0080] Please see Figure 10 , Figure 12 and Figure 13In one embodiment, the sub-unit 200 further includes a support foot 230, and the bottom of the second housing 210 is provided with a downward-opening receiving groove 214, in which the support foot 230 is movably disposed; in the stored state, the sub-unit 200 is disposed on the first base plate 112, and the support foot 230 is stored in the receiving groove 214; in the separated state, the support foot 230 can move out of the receiving groove 214 so that the support foot 230 can support the sub-unit 200, and the second air outlet 202 is higher than the bottom surface of the support foot 230 (e.g., Figure 15 (As shown).

[0081] It is understandable that the second outer casing 210 of the sub-unit 200 is provided with a second air outlet 202, which is located on the second base plate 211. The airflow passing through the sub-unit 200 is discharged downward from the second air outlet 202 on the second base plate 211, that is, the airflow passing through the sub-unit 200 is discharged downward towards the second outer casing 210.

[0082] When the slave unit 200 is in the retracted state, it is placed on the first floor. At this time, the second air outlet 202 is opposite to the first air outlet 102, allowing airflow from the slave unit 200 to smoothly exit from the second air outlet 202 along the first air outlet 102 to the outside of the first outer casing 110. Furthermore, the support foot 230 is retracted into the receiving groove 214, thus preventing the support foot 230 from occupying the height space of the receiving cavity, thereby reducing the height of the receiving cavity and consequently reducing the volume of the first outer casing 110 (e.g., ...). Figure 12 (As shown).

[0083] When the slave unit 200 is in the separated state, it is removed from the receiving cavity 111 and located outside the first outer casing 110. At this time, the support foot 230 can move to the outside of the receiving groove 214. The movement of the support foot 230 can be manually operated or automatically moved to the outside of the receiving groove 214. The support foot 230 can be moved through a rotating structure or a lifting structure, and the specific method is not limited here. The support foot 230 can be fully moved to the outside of the receiving groove 214, or only a portion of the support foot 230 can be moved to the outside of the receiving groove 214, as long as the support foot 230 moved to the outside of the receiving groove 214 can support the slave unit 200.

[0084] Furthermore, when the sub-unit 200 is in the separated state, the second air outlet 202 is higher than the bottom surface of the support foot 230, so that the second air outlet 202 and the plane containing the bottom surface of the support foot 230 are spaced apart, allowing the air blown out from the second air outlet 202 to blow downwards. This ensures that the airflow passing through the sub-unit 200 can be discharged downwards towards the second outer casing 210, thereby ensuring the performance of the sub-unit 200 (e.g., ...). Figure 15 (As shown).

[0085] Please see Figure 2 , Figure 12 and Figure 13 In one embodiment, the side plate of the first housing 110 is provided with an installation port 104 communicating with the receiving cavity 111, and the sub-machine 200 can be loaded or unloaded from the installation port 104; the support foot 230 is rotatably disposed in the receiving groove 214, and when the sub-machine 200 is loaded into the receiving cavity 111 from the installation port 104, the rotation direction of the support foot 230 is opposite to the loading direction of the sub-machine 200.

[0086] It is understood that the mounting opening 104 can be located on the front side of the first housing 110, and the mounting opening 104 is located at the lower part of the front side plate of the first housing 110. The first housing 110 also includes a switch door 113, which can be opened and closed to cover the mounting opening 104. In this embodiment, the switch door 113 can be a single door or a double door, which can be selected and designed according to actual needs. In one embodiment, the switch door 113 includes two sub-doors, which are arranged side by side along the width direction of the mounting opening 104. This makes the space occupied by the switch door 113 small when it is open, the single door movement distance small, and the control more precise. The switch door 113 is designed to open and close, covering the mounting opening 104. When the sub-unit 200 needs to be removed from the receiving cavity 111 for independent operation, simply open the switch door 113, remove the sub-unit 200 to the required room, and perform functions such as air supply, purification, humidification, dehumidification, and sterilization in the room. When the sub-unit 200 needs to be used in conjunction with the main unit 100, or when the sub-unit 200 is not in use, the sub-unit 200 can be hidden inside the main unit, and the switch door 113 can be closed, thus ensuring the consistency of the entire unit and effectively preventing dust from entering the receiving cavity 111. In other embodiments, the switch door 113 may be omitted, leaving the mounting opening 104 open, allowing the sub-unit 200 to be inserted into or removed from the receiving cavity 111 at any time.

[0087] Furthermore, the support foot 230 is provided with a rotating structure, allowing it to be rotatably disposed within the receiving groove 214. The rotating structure can be of various types, such as a gear structure, a motor structure, or a torsion spring 232 structure, etc., and is not specifically limited here. When the sub-machine 200 is inserted into the receiving cavity 111 through the mounting port 104, the sub-machine 200 is positioned on the first base plate 112. The rotation direction of the support foot 230 is opposite to the insertion direction of the sub-machine 200. The first base plate 112 provides support force to the support foot 230 and gives it a tendency to rotate. As the sub-machine 200 is inserted, the support foot 230 can automatically rotate and retract into the receiving groove 214, eliminating the need for manual operation by the user. This improves the ease of inserting the sub-machine 200, and thus enhances its applicability.

[0088] Please see Figures 12 to 14 ,as well as Figure 16 In one embodiment, the support foot 230 includes a support member 231 and a torsion spring 232. One of the support member 231 and the submachine 200 is provided with a rotating shaft 233, and the other is provided with a shaft hole 251. The torsion spring 232 is sleeved on the rotating shaft 233, and the rotating shaft 233 is rotatably disposed in the shaft hole 251. The torsion spring 232 is used to provide driving force for the rotation of the support member 231.

[0089] Specifically, in this embodiment, the support member 231 has a rotating shaft 233 at both ends. The submachine 200 also includes a base 240 and a fixing block 250. The fixing block 250 is detachably installed on the base 240. The base 240 and the fixing block 250 are spaced apart and form the receiving groove 214. The base 240 and the fixing block 250 are respectively provided with shaft holes 251 corresponding to the rotating shaft 233 of the support member 231, so that the rotating shaft 233 of the support member 231 can be rotatably installed in the corresponding shaft hole 251. Torsion spring 232 is sleeved on rotating shaft 233. Torsion spring 232 is used to provide driving force for the rotation of support member 231. That is, when support foot 230 is stored in receiving groove 214, torsion spring 232 is in a compressed state so that the torsion of torsion spring 232 can act on support member 231, so that support member 231 has a tendency to rotate. When the submachine 200 is taken out from the receiving cavity and the first base plate 112 no longer restricts support member 231, support member 231 can rotate out of receiving groove 214 along the taking out direction of submachine 200 and support submachine 200.

[0090] Understandably, the bottom of the submachine 200 is also provided with a stop 260 for limiting the support member 231 (e.g., Figure 13 and Figure 15As shown in the diagram, the stop 260 is used to block the rotation angle of the support member 231, ensuring that when the support member 231 rotates from inside the receiving groove 214 to outside the receiving groove 214, the support member 231 rotates to a position along the height direction, that is, the support member 231 is arranged vertically, so that the support member 231 can support the submachine 200. In this embodiment, the stop 260 is the groove wall of the receiving groove 214. When the submachine 200 is in the separated state, the support member 231 rotates to abut against the groove wall of the receiving groove 214 and is arranged along the height direction, so that the support member 231 can support the submachine 200 perpendicularly to the bottom surface.

[0091] Please see Figures 13 to 15 In one embodiment, the torsion spring 232 includes a first elastic arm 234 and a second elastic arm 235 disposed opposite to each other. The first elastic arm 234 is confined within the limiting groove 236 of the support member 231, and the second elastic arm 235 is stopped by the stop portion 215 of the submachine 200, so that the torsion spring 232 is in a constant compression state.

[0092] It is understood that the support member 231 is provided with a limiting groove 236 for accommodating the first elastic member, and the bottom of the accommodating groove 214 of the submachine 200 is the stop part 215. That is, the fixing block 250 of the submachine 200 can stop the second elastic arm 235. Whether the support member 231 is inside the accommodating groove 214 or outside the accommodating groove 214, the torsion spring 232 is in a compressed state. That is, the torsion spring 232 is in a normally compressed state inside the submachine 200. When the slave unit 200 is located inside the receiving cavity 111, the support member 231 is housed in the receiving groove 214. At this time, the torsion spring 232 provides the driving force for the rotation of the support member 231. When the slave unit 200 is located outside the receiving cavity 111, the support member 231 rotates to the outside of the receiving groove 214. At this time, the support member 231 supports the slave unit 200, and the stop block 260 of the slave unit 200 limits the support member 231. At this time, the torsion spring 232 provides the support member 231 with the driving force to abut against the stop block 260, so as to ensure that the support member 231 can be set along the height direction and is not easy to rotate towards the receiving groove 214. This ensures that the support member 231 can stably support the slave unit 200, thereby improving the reliability of the slave unit 200.

[0093] In one embodiment, when the torsion spring 232 is in its natural state, the angle between the first elastic arm 234 and the second elastic arm 235 is not less than 90 degrees and not greater than 180 degrees. It is understood that the receiving groove 214 in this embodiment has a square structure, which is easy to manufacture. The natural state of the torsion spring 232 is the state where the torsion spring 232 is not installed on the rotating shaft 233 of the support member 231. When the torsion spring 232 is not installed on the rotating shaft 233, the first elastic arm 234 and the second elastic arm 235 are not restricted by any structure and are in their natural state. At this time, the angle between the first elastic arm 234 and the second elastic arm 235 is not less than 90 degrees and not greater than 180 degrees. The torsion spring 232 is installed on the rotating shaft 233 of the support member 231 and disposed within the receiving groove 214. This allows the torsion spring 232 to provide driving force for the rotation of the support member 231. When the support member 231 rotates along the height direction under the drive of the torsion spring 232, the torsion spring 232, through the combined action of the first elastic arm 234 and the second elastic arm 235, provides a stable driving force to the support member 231, ensuring that the support member 231 remains aligned along the height direction and preventing fatigue of the torsion spring 232 that would result in insufficient driving force. When the driving force provided by the torsion spring 232 is insufficient, the support member 231 is prone to rotating into the receiving groove 214, thus preventing the support member 231 from stably supporting the sub-machine 200. This application avoids this situation. Therefore, the torsion spring 232 of this application can improve the stability of the support member 231 in supporting the sub-machine 200.

[0094] Please see Figure 5 , Figure 7 , Figure 8 and Figure 10 In one embodiment, the mother machine 100 further includes a locking member 130, which is movably disposed on the first base plate 112. The locking member 130 has a locking position for limiting and fixing the daughter machine 200 on the first base plate 112, and an unlocking position for separating the daughter machine 200 from the first base plate 112.

[0095] It is understandable that the locking member 130 can be movably mounted on the first base plate 112 in various ways, such as, but not limited to, rotation, sliding, lifting, etc., as long as the locking member 130 can have a locked position and an unlocked position. When the locking member 130 is in the locked position, the locking member 130 limits and fixes the sub-unit 200 so that the sub-unit 200 can be stably installed on the first base plate 112; when the locking member 130 is in the unlocked position, the locking member 130 releases the limiting and fixing of the sub-unit 200, so that the sub-unit 200 can be separated from the first base plate 112. By setting the locking member 130, the stability of the sub-unit 200 installed in the receiving cavity 111 of the mother unit 100 can be ensured, preventing the sub-unit 200 from falling out of the mother unit 100 when the sub-unit 200 is used in conjunction with the mother unit 100, thereby improving the reliability of the wall-mounted air conditioner indoor unit.

[0096] Please see Figure 7 , Figure 9 and Figure 11 In one embodiment, the locking member 130 includes a locking strip 131, which is disposed on the inner side of the first base plate 112 and rotatably disposed on the first base plate 112; the second base plate 211 is provided with a downwardly opening limiting groove 216 and a strip-shaped guide groove 217 communicating with the limiting groove 216; the locking strip 131 can slide along the strip-shaped guide groove 217 into the limiting groove 216; the locking strip 131 is rotatably disposed in the limiting groove 216 so that the locking member 130 can switch between the locked position and the unlocked position.

[0097] Understandably, the strip guide groove 217 is used to guide the locking bar 131 so that it can smoothly slide along the strip guide groove 217 into the limiting groove 216. This arrangement facilitates the insertion of the slave unit 200 into the receiving groove 214 of the mother unit 100. When the slave unit 200 is installed on the first base plate 112 and the locking bar 131 is located in the limiting groove 216, the locking bar 131 can rotate within the limiting groove 216. When the locking bar 131 rotates to be aligned with the extension direction of the strip guide groove 217, the locking bar 131 is in the unlocked position. In the unlocked position, the locking bar 131 can slide from the limiting groove 216 into the strip guide groove 217, so that the slave unit 200 can be removed from the receiving cavity 111.

[0098] When the locking bar 131 rotates to form an angle with the extending direction of the strip guide groove 217, the locking bar 131 is in the locked position. At this time, the limiting groove 216 limits the locking bar 131, so that the locking bar 131 cannot slide from the limiting groove 216 into the strip guide groove 217. The locking bar 131 is limited within the limiting groove 216, which is equivalent to the locking bar 131 limiting the slave machine 200, thereby fixing the slave machine 200 to the first base plate 112. It can be understood that the sliding of the locking bar 131 within the strip guide groove 217 can be a relative movement formed by the movement of the slave machine 200, that is, the locking bar 131 is stationary while the strip guide groove 217 moves.

[0099] Please see Figures 8 to 11 In one embodiment, the side plate of the first housing 110 is provided with an installation port 104 for the sub-machine 200 to be loaded or unloaded. The sub-machine 200 has an insertion end 204 that is loaded along the installation port 104. The strip guide groove 217 is provided on the side of the limiting groove 216 near the insertion end 204 of the sub-machine 200 and extends to the insertion end 204.

[0100] Understandably, when the sub-machine 200 is installed in the receiving cavity 111, the locking bar 131 is adjusted to the unlocked position, and the insertion end 204 of the sub-machine 200 is aligned with the installation port 104. Then, the insertion end 204 of the sub-machine 200 is pushed into the receiving cavity 111 from the installation port 104. The strip-shaped guide groove 217 at the bottom of the sub-machine 200 extends from the insertion end 204 to meet the limiting groove 216, so that the locking bar 131 can enter the strip-shaped guide groove 217 from the insertion end 204 and then slide along the strip-shaped guide groove 217 into the limiting groove 216. Conversely, when the sub-machine 200 is removed from the receiving cavity 111, the locking bar 131 is rotated to the unlocked position. The locking bar 131 can then enter the strip-shaped guide groove 217 through the limiting groove 216, slide along the strip-shaped guide groove 217, and slide out through the loading end 204 of the sub-machine 200, so that the sub-machine 200 can be smoothly removed from the receiving cavity 111. Therefore, this embodiment improves the smoothness of sub-machine 200 installation by extending the strip-shaped guide groove 217 from its intersection with the limiting groove 216 to the loading end 204 of the sub-machine 200, allowing for smooth loading and unloading of the sub-machine 200.

[0101] In one embodiment, the limiting groove 216 has a circular cross-section along the horizontal direction, and the diameter of the circular cross-section of the limiting groove 216 is greater than the width of the strip guide groove 217 at the intersection with the limiting groove 216. It can be understood that the outline formed by the locking bar 131 when rotating on the first base plate 112 is approximately cylindrical, and the limiting groove 216 has a circular cross-section along the horizontal direction, i.e., the limiting groove 216 is a cylindrical limiting groove 216, so that the shape of the limiting groove 216 matches the shape formed by the rotation of the locking bar 131. The strip guide groove 217 has an elongated structure, and the width of the strip guide groove 217 matches the width of the locking bar 131. By limiting the diameter of the circular cross-section of the limiting groove 216 to be greater than the width of the strip guide groove 217 at the intersection of the limiting groove 217 and the limiting groove 216, the locking bar 131 cannot slide from the limiting groove 216 into the strip guide groove 217 when in the locking position, thus ensuring the stability of the locking bar 131 in limiting and fixing the submachine 200.

[0102] Please see Figure 7 , Figure 9 and Figure 11 In one embodiment, the locking member 130 further includes an adjusting member 132, which is disposed on the outer side of the first base plate 112 and connected to the locking bar 131 through a connector 133. The locking bar 131 can rotate with the rotation of the adjusting member 132. The adjusting member 132 is provided with an adjusting part 134 for adjusting the rotation of the locking member 130.

[0103] Understandably, to facilitate the rotation of the locking bar 131, an adjusting member 132 is provided on the outer side of the first base plate 112. The adjusting member 132 is connected to the locking bar 131 via a connecting member 133. By driving the adjusting member 132 to rotate, the locking bar 131 can be rotated. The adjusting member 132 is located on the outer side of the first base plate 112, allowing the locking member 130 to rotate from the outer side of the first base plate 112, thus enabling the locking member 130 to switch between the locked and unlocked positions, thereby improving the portability of adjusting the locking member 130.

[0104] Furthermore, the adjusting member 132 is provided with an adjusting part 134 for adjusting the rotation of the locking member 130. The adjusting part 134 can be a protrusion or a concave part. When the adjusting part 134 is a protrusion, the locking member 130 can be rotated by holding the protrusion. When the adjusting part 134 is a concave part, the user can take the adjusting member 132 and insert it into the concave part, and rotate the adjusting member 132 to drive the locking member 130 to rotate. The adjusting member 132 here can be a conventional tool such as a card. The specific tool is not limited here, as long as the adjusting member 132 can be inserted into the concave part.

[0105] In one embodiment, the slave unit 200 further includes a power conversion module, which converts the input power and outputs it to the air handling module 220 to power the air handling module 220. It is understood that the power conversion module can be implemented using one or more combinations of voltage transformation circuits such as AC-DC circuits, DC-DC circuits, DC-AC circuits, BOOST circuits, or BUCK circuits. The power conversion module can perform power conversion such as boosting, bucking, rectifying, or inverting the input power to convert it into a power supply that meets the power supply requirements of the air handling module 220 before outputting it to the power supply terminal of the air handling module 220, thereby powering the air handling module 220.

[0106] Furthermore, the slave unit 200 may contain a battery, which is electrically connected to a power conversion module, enabling the power conversion module to supply power from the battery to the air handling module 220. In other words, the slave unit 200 can power the air handling module 220 via the battery. Alternatively, the slave unit 200 may not contain a battery. Instead, it can be electrically connected to an external power supply device via a plug assembly 270. Power from the external power supply device is supplied to the power conversion module via the plug assembly 270. The power conversion module then converts the external power and outputs it to the air handling module 220. Thus, the slave unit 200 can be powered by an external power supply device. Therefore, by incorporating a power conversion module, this application enables the slave unit 200 to power the air handling module 220 via a battery or an external power supply device, thereby improving the applicability of the slave unit 200.

[0107] Please see Figure 2 , Figure 10 , Figures 17 to 19 In one embodiment, the sub-unit 200 further includes a plug 270, the plug 270, the power conversion module, and the air handling module 220 being electrically connected in sequence; the main unit 100 further includes a socket 140, the socket 140 being electrically connected to the indoor heat exchange module; in the stored state, the plug 270 is inserted into the socket 140; in the separated state, the plug 270 is separated from the socket 140.

[0108] Understandably, when the sub-unit 200 is in the retracted state, the plug 270 is inserted into the socket 140, meaning the main unit 100 supplies power to the sub-unit 200, and the sub-unit 200 and main unit 100 can work together. When the sub-unit 200 is in the detached state, the plug 270 is disconnected from the socket 140, and the plug 270 of the sub-unit 200 can be inserted into an external socket 140, supplying power to the sub-unit 200 through an external power supply device, allowing the sub-unit 200 to work independently. By providing the plug 270 on the sub-unit 200 and the socket 140 on the main unit 100, the sub-unit 200 and main unit 100 can work together, and when the sub-unit 200 is disconnected from the main unit 100, both the main unit 100 and the sub-unit 200 can work independently, thus improving the applicability of the wall-mounted air conditioner indoor unit.

[0109] In one embodiment, the orientation of the plug of the socket 140 is the same as the opening direction of the mounting port 104 on the first housing 110. In this embodiment, the plug of the socket 140 is positioned facing forward, and the opening direction of the mounting port 104 of the first housing 110 is also facing forward. When the slave unit 200 is installed in the receiving cavity 111 of the mother unit 100, the plug 270 is inserted into the socket 140 from front to back at the mounting port 104. This arrangement improves the visibility of the plug 270 and the socket 140, thereby facilitating the electrical connection between the slave unit 200 and the mother unit 100.

[0110] Please see Figure 1 , Figure 2 and Figure 17 In one embodiment, the indoor heat exchange module has a heat exchange duct, and the upper part and / or middle part of the side plate of the first housing 110 are provided with a heat exchange air inlet 105 and a heat exchange air outlet 106 communicating with the heat exchange duct. The heat exchange duct is separated from the receiving cavity 111.

[0111] Specifically, the first outer casing 110 includes multiple side plates, a first bottom plate 112, and a first top plate. The multiple side plates are mounted on the first bottom plate 112, and the first top plate covers the multiple side plates. The multiple side plates, the first bottom plate 112, and the first top plate enclose and form a cavity structure. A heat exchange air inlet 105 is located on one of the side plates of the first outer casing 110, and a heat exchange air outlet 106 is located on the other side plate of the first outer casing 110. This arrangement allows the airflow to exit from the side of the first outer casing 110 after passing through the indoor heat exchange module of the mother unit 100. That is, in this embodiment, the hot or cold air of the mother unit 100 can exit from the side of the first outer casing 110.

[0112] Furthermore, a partition is provided between the heat exchange air duct and the receiving cavity 111 so that the heat exchange air duct and the receiving cavity 111 are independent of each other and do not affect each other. When the sub-unit 200 is located inside the mother unit 100 or separated from the mother unit 100, it will not affect the heat exchange effect of the indoor heat exchange module, thus ensuring the heat exchange stability of the wall-mounted air conditioner indoor unit.

[0113] The present invention also proposes an air conditioner, which includes an outdoor unit connected by a refrigerant pipe and a wall-mounted indoor unit as described above.
