[0057] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0058] In the description of the present application, it should be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element. The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, it may be internal connectivity between two elements or an interactive relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0059] In the description of the present application, it should be understood that the terms "height", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. used in the present application to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0060] In the description of this application, it should be understood that the terms "first" and "second" are used in this application for descriptive purposes only, and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0061] In the present application, the air conditioner performs a refrigeration cycle or a heating cycle of the air conditioner through a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle and the heating cycle include a series of processes such as compression, condensation, expansion and evaporation, and provide cooling or heat to the indoor space through the heat absorption or heat release of the refrigerant to adjust the temperature of the indoor space.

[0062] The compressor compresses the refrigerant gas in a high temperature and high pressure state 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.

[0063] 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 refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration 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.

[0064] The air conditioner of the present application includes an air conditioner indoor unit and an air conditioner outdoor unit, the air conditioner outdoor unit refers to a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve can be provided in the indoor unit or the outdoor unit.

[0065] 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.

[0066] Reference below Figure 1-Figure 13 The air conditioner indoor unit of an embodiment of the present application is described, including a shell 1A and an air guide assembly 2A, wherein the shell 1A serves as the outer shell of the air conditioner indoor unit, constituting a protective structure and an installation structure of the air conditioner indoor unit, and the air guide assembly 2A is arranged in the shell 1A, and is used to guide the direction of airflow blown into the room.

[0067] It should be noted that the air guide assembly 2A generally controls the airflow through the air guide plate 3A, and the direction of the airflow blowing into the room changes periodically by rotating the air guide plate 3A. According to the design requirements of the air conditioner, the arrangement direction of the air guide plate 3A can be horizontal or vertical.

[0068] like Figure 2-5As shown, the air guide assembly 2A of the present application includes a motor 1 and a motor shield 2, which serve as a power source for driving the air guide plate 3A to rotate, and drive the air guide plate 3A to rotate relative to the housing 1A. Specifically, the motor 1 includes a motor body 1a and a fixed arm 1b extending toward the outside of the motor body 1a, wherein the number of the fixed arms 1b is at least two, preferably two in this embodiment, and the two fixed arms 1b are symmetrically arranged on both sides of the motor body 1a, and each fixed arm 1b has a fixed hole 1c penetrating the fixed arm 1b, and the fixed hole 1c penetrates the fixed arm 1b along the thickness direction of the fixed arm 1b to form a through-hole structure.

[0069] It can be understood that the motor 1 is connected to the air guide plate 3A through a linkage structure and a transmission structure, and the periodic rotation of the motor shaft of the motor 1 can drive the air guide plate 3A to rotate periodically, thereby causing the direction of the airflow blowing into the room to change periodically.

[0070] The motor shield 2 is disposed in the housing 1A, and is used to install and fix the position of the motor 1. Generally speaking, the position of the motor shield 2 in the housing 1A is related to the arrangement direction of the air guide plate 3A. The motor 1 is installed and fixed in the motor shield 2, and the transmission with the air guide plate 3A is realized through the linkage structure and the transmission structure. A motor cavity 3 is formed in the motor shield 2 to accommodate the motor 1. According to the shape of the outer contour of the motor 1 itself, the shape and contour of the motor cavity 3 can be diverse, so that the motors 1 with different outer contours can be adapted and installed in the corresponding motor cavity 3, and each motor cavity 3 will have an opening 2c for the power supply 1 to enter and exit the motor cavity 3, and the opening 2c is arranged at the top of the motor cavity 3, so that the assembler can install the motor 1 into the motor cavity 3.

[0071] like Figure 6-9 As shown, in some embodiments, the motor shield 2 includes a bottom plate 2a and a side plate 2b, wherein:

[0072] The bottom plate 2a constitutes the bottom of the motor cavity 3, and the bottom plate 2a has an output hole 20a extending from the output end of the power supply machine 1; the side plate 2b is connected to the bottom plate 2a and is arranged around the output hole 20a, and the side plate 2b and the bottom plate 2a are connected to each other to form a motor cavity 3 with an opening 2c at the top; and the side plate 2b includes a bending portion 20b, the position of the bending portion 20b corresponds to the position of the fixed arm 1b, and the contour of the bending portion 20b is adapted to the outer contour of the fixed arm 1b, so that after the motor 1 is attached to the motor cavity 3, the bending portion 20b can limit the movement of the fixed arm 1b of the motor 1 in all directions.

[0073] It can be understood that the contour shape of the side plate 2b surrounding the output hole is adapted to the outer contour shape of the motor body 1a, so that when the motor 1 is attached to the bottom of the motor cavity 3, the side plate 2b surrounds the side wall of the motor body 1a, limiting the freedom of movement of the motor body 1a in the motor cavity 3. In addition to enclosing the motor cavity 3, the side plate 2b can also extend to the outside of the motor cavity 3 to form a connection structure and a protective structure of the motor shield 2, so that the motor shield 2 can be assembled into the housing 1A.

[0074] like Figure 6-9 As shown, the motor shield 2 of the present application includes a limit block 4, a first limit buckle 5 and an avoidance position 6, wherein:

[0075] The stopper 4 is a columnar structure, which is disposed at the bottom of the motor cavity 3 and has a guide direction toward the opening 2c of the motor cavity 3. In addition, the stopper 4 is configured to be able to penetrate into the fixing hole 1c to guide the motor 1 to enter the motor cavity 3 along the guide direction of the stopper 4.

[0076] It can be understood that, according to the number of fixed arms 1b of the motor 1, the number of limit blocks 4 is also set to two, and the two limit blocks 4 are arranged corresponding to the fixing holes 1c of the fixed arms 1b. When the motor 1 enters the motor cavity 3, the fixing holes 1c and the limit blocks 4 calibrate the position of the motor 1, and after the limit blocks 4 penetrate the fixing holes 1c, the limit blocks 4 limit the freedom of movement of the fixed arms 1b, so that the fixed arms 1b have and only have a single degree of freedom to move along the guide direction of the limit blocks 4, and the motor 1 moves into the motor cavity 3 along the guide direction of the limit blocks 4 and fits the bottom of the motor cavity 3.

[0077] It can be understood that the outer diameter of the limit block 4 is compatible with the inner diameter of the fixing hole 1c, so that when the limit block 4 is inserted into the fixing hole 1c, the limit block 4 and the fixing hole 1c can form a positioning fit, so that the limit block 4 can limit the circumferential movement of the fixed arm 1b toward the limit block 4, thereby realizing the limiting and positioning of the motor 1.

[0078] like Figure 6-13 As shown, the first limit buckle 5 is arranged beside the limit block 4 and arranged on the side plate 2b of the motor shield 2. The number of the first limit buckle 5 is also two, corresponding to the number of the limit blocks 4, and the first limit buckle 5 is configured to be elastically deformed by being squeezed by the fixed arm 1b of the motor 1 when the motor 1 enters the motor cavity 3; and after the motor 1 fits the motor cavity 3, it presses against the top of the fixed arm 1b to fix the motor 1 in the motor cavity 3; the avoidance position 6 is used to accommodate the first limit buckle 5, and is used to allow the first limit buckle 5 to be elastically deformed to the side of the limit block 4 when the motor 1 enters the motor cavity 3.

[0079] It is understandable that when the motor 1 enters the motor shield 2 through the opening 2c of the motor cavity 3, the fixed arm 1b of the motor 1 will enter between the first limit buckle 5 and the side plate 2b of the motor shield 2, and the fixed arm 1b squeezes the first limit buckle 5, so that the first limit buckle 5 elastically deforms and retreats into the avoidance position 6, so that the fixed arm 1b is inserted into the limit block 4 until the motor body 1a and the fixed arm 1b fit the bottom of the motor cavity 3. Generally speaking, the first limit buckle 5 can be made of a material with certain elasticity and hardness such as plastic, so that the first limit buckle 5 can be elastically deformed based on the squeezing of the fixed arm 1b, and can have sufficient structural strength, so that the fixed arm 1b can be pressed by the first limit buckle 5. When the first limit buckle 5 is no longer squeezed by external force, the first limit buckle 5 rebounds to the initial position based on its own elasticity, so that the first limit buckle 5 presses against the top of the fixed arm 1b, and the motor 1 is limited in the guide direction of the limit block 4.

[0080] Since the first limit buckle 5 has an elastic deformation direction perpendicular to the guide direction of the limit block 4, that is, the guide direction of the limit block 4 is vertical, and the elastic deformation direction of the first limit buckle 5 is horizontal. Therefore, when the motor 1 enters the motor cavity 3 along the vertical direction, that is, the guide direction of the limit block 4, the first limit buckle 5 will deform in the horizontal direction, thereby making the elastic deformation direction of the first limit buckle 5 and the guide direction of the limit block 4 mutually perpendicular, and when the motor 1 is assembled in place, the freedom of the motor 1 to move around the motor cavity 3 is limited by the limit block 4, so that the limit block 4 bears the lateral load brought by the motor 1, and the first limit buckle 5 only bears the vertical load, and when the first limit buckle 5 is pressed against the top of the fixed arm 1b, the first limit buckle 5 will not produce longitudinal deformation or will only produce extremely slight longitudinal deformation based on the pressure generated by the vertical load it carries, thereby making the first limit buckle 5 have good stability in the vertical direction. In this way, even if the air conditioner vibrates or the motor shield 2 encounters external force, it will not affect the vertical limiting stability of the first limiting buckle 5. The first limiting buckle 5 can always be pressed against the top of the fixed arm 1b to achieve vertical limiting fixation of the motor 1.

[0081] The motor 1 is limited in other directions by the limit block 4. The limit block 4 is fixed on the motor shield 2 without elasticity, and also has good limit stability. In this way, when the fixed arm 1b is passed through the limit block 4, the first limit buckle 5 realizes the limit fixation of the motor 1 in the vertical direction, and the limit block 4 realizes the limit fixation of the motor 1 in the horizontal direction, so that the motor 1 can be limited and fixed in a screwless assembly mode, thereby improving the assembly efficiency of the motor 1. Moreover, based on the non-deformation design of the first limit buckle 5 in the vertical direction and the non-deformation design of the limit block 4, the motor 1 can have good structural stability when it is passed through the limit block 4.

[0082] In some embodiments, Figure 6-12As shown, the first limit buckle 5 is arranged beside the limit block 4 and is located on the side wall of the motor shield 2. The first limit buckle 5 includes a first connecting portion 5a and a first limit portion 5b, wherein:

[0083] The first connection portion 5a is connected to the side wall of the motor shield 2 and is suspended at the bottom of the motor cavity 3, so that an avoidance position 6 is formed between the first connection portion 5a and the bottom of the motor cavity 3;

[0084] The first limiting portion 5b is arranged in the avoidance position 6, and one end of the first limiting portion 5b is connected to the first connecting portion 5a, and the other end of the first limiting portion 5b is suspended at the bottom of the motor cavity 3, so that when the first limiting portion 5b is squeezed by the motor 1, it moves relative to the first connecting portion 5a, generating elastic deformation perpendicular to the guide direction of the limiting block 4, and the first limiting portion 5b extends toward the bottom of the motor cavity 3, and a gap is reserved between the first limiting portion 5b and the bottom of the motor cavity 3, and the size of the gap is adapted to the thickness of the fixed arm 1b, and,

[0085] At least a portion of the first limiting portion 5b extends into the motor cavity 3, so that when the motor 1 enters the motor cavity 3, the fixed arm 1b can squeeze the first limiting portion 5b, so that the first limiting buckle 5 can be squeezed by the motor 1 and elastically deformed when the motor 1 enters the motor cavity 3; and, after the motor 1 fits the motor cavity 3, it presses against the top of the fixed arm 1b to fix the motor 1 in the motor cavity 3.

[0086] It should be noted that the first connecting portion 5a is fixedly connected to the side wall of the motor shield 2, and the first connecting portion 5a does not have the function of elastic deformation, so that the first connecting portion 5a can serve as a vertical positioning reference for the first limit buckle 5, so that the first limit buckle 5 does not produce elastic deformation in the vertical direction.

[0087] The avoidance position 6 is formed between the first connection part 5a and the bottom of the motor cavity 3. The first limiting part 5b is connected to the lower end of the first connection part 5a and is located in the avoidance position 6, so that the first limiting part 5b is squeezed by the fixed arm 1b, and will rotate relative to the first connection part 5a with the first connection part 5a as the deformation base point, and retreat into the avoidance position 6. In this way, during the elastic deformation of the first limiting part 5b, the size of the gap reserved between the first limiting part 5b and the bottom of the motor cavity 3 will not change significantly. When the fixed arm 1b is attached to the bottom of the motor cavity 3, the first limiting part 5b can return to its initial position and press against the top of the fixed arm 1b.

[0088] It can be understood that the first limiting portion 5b partially extends into the motor cavity 3, which will cause the distance between the side panel 2b of the motor cavity 3 and the first limiting buckle 5 to gradually decrease when vertically approaching the limiting block 4, so that when the fixed arm 1b vertically enters the distance between the side panel 2b and the first limiting buckle 5, the side edge of the fixed arm 1b can squeeze the end face of the first limiting portion 5b, causing the first limiting portion 5b to deform and retreat into the avoidance position 6.

[0089] Specifically, the first limiting portion 5b includes a first extrusion section 50b and a first limiting section 51b, wherein one end of the first extrusion section 50b is elastically connected to the first connecting portion 5a, and the other end is connected to the first limiting section 51b, the first extrusion section 50b is formed on the side of the first limiting portion 5b toward the limiting block 4, and extends into the motor cavity 3 to be squeezed by the fixed arm 1b and guide the fixed arm 1b to slide into the limiting block 4; the first limiting section 51b is formed on the side of the first limiting portion 5b toward the bottom of the motor cavity 3 to press against the top of the fixed arm 1b after the first limiting portion 5b elastically recovers.

[0090] It should be noted that the first extrusion section 50b and the first limiting section 51b are two interconnected structures with the first limiting buckle 5 facing the motor cavity 3. A chamfered structure can be set between the first extrusion section 50b and the first limiting section 51b to ensure that the first limiting section 51b can retreat to the initial position and press against the top of the fixed arm 1b.

[0091] In some embodiments, the motor shield 2 includes a second limit buckle 7, which is configured to be elastically deformed by being squeezed by the motor 1 when the motor 1 enters the motor cavity 3; and, after the motor 1 fits the motor cavity 3, the second limit buckle 7 is pressed against the top of the motor body 1a to fix the motor 1 in the motor cavity 3.

[0092] Specifically, the second limiting buckle 7 includes a second connecting portion 7a and a second limiting portion 7b, one end of the second connecting portion 7a is elastically connected to the motor shield 2, and the other end of the second connecting portion 7a extends toward the opening 2c of the motor cavity 3 and is suspended on the motor shield 2. At the same time, the other end of the second connecting portion 7a is connected to the second limiting portion 7b, so that the second limiting portion 7b is located at the end of the second connecting portion 7a away from the bottom of the motor cavity 3, so that when the motor 1 enters the motor cavity 3, the second limiting portion 7b can be squeezed by the motor body 1a, and then the second limiting portion 7b and the second connecting portion 7a are elastically deformed toward the outside of the motor cavity 3, and after the motor 1 is attached to the motor cavity 3, the second limiting portion 7b returns to its initial position because it is no longer squeezed by the motor 1, and then presses against the top of the motor body 1a, so that the motor 1 is fixed in the motor cavity 3.

[0093] It is understandable that when the motor 1 enters the motor cavity 3, the motor body 1a will squeeze the second limiting portion 7b, so that the second limiting portion 7b and the second connecting portion 7a are deformed toward the outside of the motor cavity 3, so that the motor body 1a passes through the second limiting portion 7b. Similar to the first limiting buckle 5, the second limiting buckle 7 can be made of a material with certain elasticity and hardness, such as plastic, so that the second limiting buckle 7 can be elastically deformed based on the squeezing of the motor body 1a, and can have sufficient structural strength, so that the motor body 1a can be pressed against by the second limiting buckle 7. A guide structure can be provided on the second limiting portion 7b, so that the motor body 1a can squeeze the second limiting portion 7b along the guidance of the guide structure, so that the second limiting portion 7b is deformed.

[0094] It should be noted that the second limit buckle 7 and the first limit buckle 5 are respectively arranged on the peripheral side of the motor cavity 3, or the second limit buckle 7 and the first limit buckle 5 can be arranged on the peripheral side of the output hole, so that the first limit buckle 5 and the second limit buckle 7 cooperate with each other to form a multi-point limit and fixation layout for the motor body 1a and the fixed arm 1b of the motor 1.

[0095] It can be understood that when the motor 1 enters the motor cavity 3, the second limiting portion 7b can be squeezed by the motor body 1a, so that the second limiting portion 7b and the second connecting portion 7a are stretched toward the outside of the motor cavity 3. At this time, the second connecting portion 7a and the second limiting portion 7b are bent and deformed, and the second connecting portion 7a and the second limiting portion 7b are bent toward the outside of the motor cavity 3, generating an elastic deformation that is perpendicular to the guiding direction of the limiting block 4. In this way, when the motor 1 enters the motor cavity 3 vertically, that is, in the guiding direction of the limiting block 4, the second limiting buckle 7 will change in lateral deformation. When the motor 1 is assembled in place, the freedom of the motor 1 to move around the motor cavity 3 is limited by the limit block 4, so that the limit block 4 bears the lateral load brought by the motor 1, and the second limit buckle 7 only bears the vertical load. When the second limit buckle 7 is pressed against the top of the motor body 1a, the second limit buckle 7 will not produce longitudinal deformation or only produce extremely slight longitudinal deformation based on the pressure generated by the vertical load it carries, thereby making the second limit buckle 7 also have good stability in the vertical direction.

[0096] Based on the aforementioned structure of the indoor unit of the air conditioner, the assembly process of the driving motor 1 of the air guide plate 3A of the indoor unit of the air conditioner provided in the preferred embodiment of the present application is as follows:

[0097] When the motor 1 is installed into the motor cavity 3, the motor body 1a touches the second limit buckle 7 and squeezes the second limit buckle 7, so that the second limit buckle 7 retreats to the outside of the motor cavity 3. After the motor body 1a passes through the second limit buckle 7, the second limit part 7b returns to its initial position under the elastic recovery of the second connecting part 7a and presses against the top of the motor body 1a, thereby realizing the vertical limit fixation of the motor body 1a.

[0098] Furthermore, during the process of installing the motor 1 into the motor cavity 3, the fixed arm 1b penetrates the limit block 4 based on the fixing hole 1c, and squeezes the first limit portion 5b of the first limit buckle 5, so that the first limit portion 5b is laterally retreated into the avoidance position 6, and the fixed arm 1b moves to the bottom of the motor cavity 3 along the guide direction of the limit block 4. After the fixed arm 1b passes through the first limit buckle 5, the first limit portion 5b is restored to the initial position under the elastic recovery of the first connecting portion 5a, and is pressed against the top of the fixed arm 1b, so that the fixed arm 1b is fixed in the vertical direction. At the same time, based on the cooperation between the fixing hole 1c and the limit block 4, the fixed arm 1b is fixed in the horizontal direction, so that the motor 1 is installed and fixed in the motor cavity 3 in a screwless assembly manner.

[0099] Based on the aforementioned air conditioner indoor unit, some embodiments of the present application also provide an air conditioner, which includes the aforementioned air conditioner indoor unit and air conditioner outdoor unit, wherein the air conditioner outdoor unit has an outdoor heat exchanger, and the air conditioner indoor unit has an indoor heat exchanger, and the outdoor heat exchanger and the indoor heat exchanger are interconnected to realize a heat exchange cycle.

[0100] Since the air conditioner has the structure of the aforementioned air conditioner indoor unit, when the air guide assembly 2A of the air conditioner is assembled, the motor 1 driving the air guide plate 3A can also be installed and fixed in the motor cavity 3 in a screwless assembly manner, and has the advantages of the aforementioned air conditioner indoor unit.

[0101] In summary, the air conditioner indoor unit and air conditioner provided in the embodiment of the present application adopt an air guide assembly 2A with a motor shield 2, and a limit block 4 is set in the motor shield 2, so that the motor 1 with a fixed arm 1b can enter the motor cavity 3 of the motor shield 2 along the guide direction of the limit block 4, and by setting the first limit buckle 5 and the avoidance position 6, the first limit buckle 5 can be elastically deformed to the side of the limit block 4 based on the extrusion of the motor 1, so that when the fixed arm 1b is sleeved on the limit block 4, the first limit buckle 5 can press against the top of the fixed arm 1b, thereby realizing the movement limit of the motor 1 in and out of the motor cavity 3. The limit block 4 cooperates with the fixed arm 1b to realize the movement limit of the motor 1 in the circumferential direction of the limit block 4, and the motor 1 is assembled without screws, which effectively improves the assembly efficiency of the motor 1. Moreover, the elastic deformation direction of the first limit buckle 5 is perpendicular to the guide direction of the limit block 4, and the first limit buckle 5 has no elastic deformation in the guide direction of the limit block 4. In this way, even if the air conditioner vibrates or the motor shield 2 encounters external force, it will not affect the vertical limiting stability of the first limiting buckle 5. The first limiting buckle 5 can always be pressed against the top of the fixed arm 1b to achieve vertical limiting fixation of the motor 1.

[0102] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
