Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more particularly to an air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, people typically install air conditioners on the ceiling of a room to regulate the temperature of the indoor air.

[0004] In the existing technology, the electric heater in the main unit of the air conditioner indoor unit is fixed to the end plates on both sides of the evaporator by screws. The installation of the electric heater by screws is cumbersome, and it is not convenient for operators to disassemble the electric heater during later maintenance and replacement, which reduces the assembly efficiency. Utility Model Content

[0005] This application discloses an air conditioner that can fix an electric heater by plugging it in, which simplifies the installation of the electric heater and improves assembly efficiency.

[0006] To achieve the above objectives, some embodiments of this application provide an air conditioner, including:

[0007] Indoor unit, the indoor unit includes:

[0008] The housing has a cavity inside;

[0009] A fan is disposed within the receiving cavity and is used to blow air into the room;

[0010] An evaporator is disposed within the receiving cavity and is used for heat exchange of air;

[0011] An electric heater is disposed within the receiving cavity, and the evaporator portion surrounds the electric heater, the electric heater having a first end and a second end opposite each other along the axial direction of the fan;

[0012] A first support member is fixed relative to the housing, the first support member is located on one side of the axial direction of the fan, and is connected to one end of the evaporator;

[0013] The second support member is fixed relative to the housing, and is arranged facing the first support member along the axial direction of the fan, and is connected to the other end of the evaporator.

[0014] The first support member is provided with a mounting hole, which passes through the first support member along the axial direction of the fan, and the first end is inserted into the mounting hole. The mounting hole is used to fix the electric heater along the radial direction of the fan.

[0015] The second support member is provided with a slot, the opening of which penetrates the first sidewall of the second support member along the radial direction of the fan, so that the second end of the electric heater can be inserted into the slot along the radial direction of the fan.

[0016] Thus, the electric heater can be quickly installed through the mounting holes of the first support and the slots of the second support. During installation, simply insert the first end of the electric heater into the mounting hole of the first support to limit the first end of the electric heater radially towards the fan, and then insert the second end of the electric heater radially into the slot of the second support to complete the installation. This replaces the method of fixing the electric heater to the first and second support with screws, making the installation of the electric heater more convenient and faster, improving assembly efficiency. At the same time, this plug-in installation method of the electric heater is easy to disassemble, making it convenient to repair and replace the electric heater when it needs to be repaired later, thus reducing maintenance costs and time.

[0017] In some embodiments of this application, the indoor unit further includes an elastic hook, which is disposed on the second support member and located at the opening of the slot. The elastic hook can elastically deform when the second end of the electric heater is engaged in the slot to avoid the second end, and the elastic hook can prevent the second end from coming out of the opening of the slot after the second end of the electric heater is engaged in the slot.

[0018] Thus, the elastic hook at the opening of the slot can elastically deform when the second end of the electric heater is inserted into the slot, thereby smoothly avoiding the second end of the electric heater and allowing it to enter the slot. When the second end of the electric heater is fully inserted, the elastic hook will return to its original shape and tightly lock the second end of the electric heater, effectively preventing it from coming out of the slot due to vibration or external force during operation, ensuring the stable installation of the electric heater.

[0019] In some embodiments of this application, the elastic hook includes a first hook and a second hook, the first hook and the second hook being arranged opposite each other along the radial direction of the fan, the second end of the electric heater being provided with a first engaging portion and a second engaging portion, the first engaging portion and the second engaging portion being arranged opposite each other along the radial direction of the fan, the first hook engaging with the first engaging portion, and the second hook engaging with the second engaging portion.

[0020] Thus, the double-clamping method, through the engagement of the first hook with the first clamping part and the engagement of the second hook with the second clamping part, ensures a more stable installation of the electric heater, enhances the stability of the electric heater during fan operation, and reduces the risk of loosening or falling off due to vibration or external force.

[0021] In some embodiments of this application, the first hook includes a first engaging surface, which is used to abut against the first engaging portion, and the first engaging surface is configured to restrict the first engaging portion from moving out of the opening of the slot. When the second end of the electric heater moves out of the opening of the slot, the first engaging surface can drive the first hook to move towards the first engaging portion under the pressure of the first engaging portion.

[0022] In this way, the first engaging surface can move the first hook away from the first engaging portion under pressure, achieving flexibility and release of the connection. When the electric heater needs to be disassembled or replaced, the user can release the connection with a simple operation (such as pushing or pulling). As the first engaging portion moves out of the slot opening, the first engaging surface can gradually release stress, rather than suddenly breaking like a rigid connection. This helps extend the service life of the first hook and reduce damage caused by stress concentration.

[0023] In some embodiments of this application, the second hook includes a second engaging surface for abutting against the second engaging portion, and the second engaging surface is configured to restrict the second engaging portion from moving out of the opening of the slot.

[0024] Thus, the second snap-fit ​​surface is configured to restrict the movement of the second snap-fit ​​portion outward from the opening of the slot. This ensures that the electric heater will not easily fall off due to external force or vibration after snapping, improving the stability and reliability of the snap-fit. Since the second snap-fit ​​surface can directly abut against and lock the second snap-fit ​​portion, this simplifies the installation process, reduces installation costs, and improves installation efficiency.

[0025] In some embodiments of this application, the first hook includes a first connecting arm and a first protrusion. The first connecting arm is connected to the second support member. The surface of the first connecting arm facing the first latching portion is a first abutting surface. The first protrusion is disposed at one end of the first abutting surface near the opening of the slot. The first latching surface is disposed on the side of the first protrusion away from the opening of the slot. The included angle between the first latching surface and the first abutting surface is an obtuse angle.

[0026] Thus, the obtuse angle design between the first contact surface and the first abutment surface helps to reduce stress concentration on the first hook. The obtuse angle structure can distribute stress more evenly when subjected to external force, thereby reducing the risk of the first hook being damaged due to stress concentration.

[0027] In some embodiments of this application, the second hook includes a second connecting arm and a second protrusion. The surface of the second connecting arm facing the second latching portion is a second abutting surface. The second protrusion is disposed at one end of the second abutting surface near the opening of the slot. The second latching surface is disposed on the side of the second protrusion away from the opening of the slot, and the second latching surface is perpendicular to the second abutting surface.

[0028] Thus, the right-angle design between the second engaging surface and the second abutting surface provides additional support. When the second hook abuts against the second engaging part, this right-angle structure prevents the second hook from rotating or sliding under force, further enhancing the stability of its engagement.

[0029] In some embodiments of this application, the second support member further includes a blocking portion located on the side of the slot away from the electric heater, the blocking portion abutting against the second end to limit the electric heater along the axial direction of the fan.

[0030] Thus, the blocking part effectively restricts the movement of the electric heater in the fan's axial direction. This allows the electric heater to maintain a more stable position during operation, reducing axial displacement caused by vibration or external forces, thereby improving the overall stability and reliability of the air conditioner. In extreme cases, such as encountering strong vibration or external impact, the electric heater may detach from the slot. Due to the presence of the blocking part, the electric heater is effectively blocked in the axial direction, greatly reducing the risk of detachment.

[0031] In some embodiments of this application, the blocking part is a baffle, and the extending direction of the baffle is perpendicular to the axial direction of the fan.

[0032] In this way, the baffle's extension direction is set perpendicular to the fan's axis, ensuring that the contact area between the baffle and the second end of the electric heater is maximized, thereby providing a stronger limiting effect on the electric heater in the fan's axis, and further ensuring the stable installation of the electric heater.

[0033] In some embodiments of this application, the second support member further includes a reinforcing rib disposed on the side of the blocking portion opposite to the electric heater.

[0034] Thus, the addition of reinforcing ribs significantly enhances the structural strength of the blocking part, enabling it to better withstand the pressure from the electric heater and the vibration and impact forces generated during the operation of the fan. Furthermore, the addition of reinforcing ribs can also enhance the stability of the blocking part during installation. When the electric heater is installed into the slot, the additional support provided by the reinforcing ribs can more firmly fix the electric heater in place, preventing it from shifting or falling off during operation.

[0035] In some embodiments of this application, the indoor unit further includes:

[0036] A motor protective component is located outside the opening of the slot and abuts against the first sidewall.

[0037] Thus, by placing the motor guard outside the slot opening and abutting against the first side wall of the second support member, the second end of the electric heater contacts the motor guard on the side facing the fan, allowing the motor guard to further limit the electric heater in the radial direction of the fan, preventing the second end of the electric heater from detaching from the slot.

[0038] In some embodiments of this application, the motor protective component includes a first outer contour surface for abutting against the first sidewall, the first sidewall being adapted to the first outer contour surface.

[0039] In this way, by matching the first outer contour surface of the motor guard with the first side wall, it is ensured that the motor guard can fit tightly against the first side wall during installation, thereby ensuring that the motor guard can fit tightly against the second end of the electric heater, and ensuring the stable installation of the second end of the electric heater in the radial direction of the fan.

[0040] In some embodiments of this application, a preset gap exists between the peripheral wall of the first end and the wall of the mounting hole.

[0041] Thus, the pre-set gap between the peripheral wall of the first end of the electric heater and the wall of the mounting hole allows for some adjustment space at the first end of the electric heater during installation, making it easy for installers to make fine adjustments during the installation process to ensure that the electric heater can be installed correctly and stably in the predetermined position.

[0042] In some embodiments of this application, the cross-sectional dimension of the first end gradually decreases in the direction away from the second end.

[0043] Thus, the fact that the cross-sectional dimension of the first end of the electric heater gradually decreases in the direction away from the second end means that the first end of the electric heater is inclined. When the first end of the electric heater is installed into the mounting hole, the inclination of the first end has a certain guiding effect, making it easier for the first end of the electric heater to be inserted into the mounting hole. In addition, the inclination of the first end also helps to prevent the first end from rubbing against the mounting hole and prevent damage to the first end of the electric heater.

[0044] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0045] An air conditioner provided in this application includes an indoor unit, which includes a casing, a fan, an evaporator, an electric heater, a first support member, and a second support member. A receiving cavity is formed within the casing. The evaporator is disposed within the receiving cavity for heat exchange with air. The electric heater is disposed within the receiving cavity, and the evaporator partially surrounds the electric heater. The electric heater has a first end and a second end opposite to each other along the axial direction of the fan. The first support member is disposed on one side along the axial direction of the fan and connected to one end of the evaporator. The second support member is disposed opposite to the first support member along the axial direction of the fan and connected to the other end of the evaporator. The first support member has a mounting hole that penetrates the first support member along the axial direction of the fan for fixing the electric heater radially along the fan. The second support member has a slot, the opening of which penetrates the first sidewall of the second support member radially along the fan, so that the second end of the electric heater can be inserted into the slot radially along the fan. In this way, by inserting the first end of the electric heater into the mounting hole of the first support member and inserting the second end of the electric heater into the slot of the second support member along the radial direction of the fan, the electric heater can be fixed at the same time, and the electric heater can be installed quickly, replacing the cumbersome screw fixing method. This makes it easier for operators to operate when maintaining or replacing the electric heater in the later stage, and improves the assembly efficiency. Attached Figure Description

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0076] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0077] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0078] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0079] Currently, the electric heaters in air conditioner indoor units are fixed to the mounting plate for the evaporator with screws. During installation, the operator needs to hold one end of the heater by hand, then fix the other end to the mounting plate with screws, and then use screws to fix the unfixed end of the heater to the mounting plate. This screw-based installation method makes it inconvenient for operators to install, repair, or replace the heater, reducing the assembly efficiency of the electric heater.

[0080] To address the aforementioned issues, this application provides an air conditioner that can fix an electric heater via a plug-in connection, simplifying the installation of the electric heater and improving assembly efficiency.

[0081] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0082] Please see Figure 1This application provides an embodiment of an air conditioner 100, which includes an indoor unit 101. The indoor unit 101 is an important component of the air conditioner 100, and it performs a refrigeration cycle using a compressor, condenser, expansion valve, etc. The refrigeration cycle includes a series of processes involving compression, condensation, throttling, and evaporation, supplying cooling or heating energy to the regulated and heat-exchanged air. The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it at a high temperature and high pressure. The discharged refrigerant gas flows into the condenser, where it condenses the compressed refrigerant into a liquid phase, releasing heat to the surrounding environment through the condensation process. The expansion valve throttles the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure gas-liquid two-phase refrigerant. After absorbing heat and evaporating in the expansion valve, the refrigerant is in a low-temperature, low-pressure state. The refrigerant gas then returns to the compressor, where it exchanges heat with the material to be cooled using the latent heat of vaporization of the refrigerant, achieving a cooling effect. This allows the indoor unit 101 to regulate the temperature of the indoor space. In this embodiment, the indoor unit 101 is mounted on the ceiling of the room.

[0083] like Figure 2 and Figure 3 As shown, the indoor unit 101 includes a housing 1, and a receiving cavity 1a is formed inside the housing 1. Components such as a compressor and a condenser are arranged inside the receiving cavity 1a.

[0084] like Figures 4 to 6 As shown, the indoor unit 101 also includes a fan 2, which is disposed in the receiving cavity 1a. The fan 2 can drive airflow when it rotates, and is used to supply cold air or hot air to the room.

[0085] The indoor unit 101 also includes an evaporator 3, which is disposed within the housing cavity 1a. The evaporator 3 is a heat exchanger that utilizes the characteristic that liquid low-temperature refrigerant easily evaporates under low pressure. By absorbing heat from the cooled medium, it lowers the temperature of the surrounding air, thereby achieving a cooling effect. With the assistance of the fan 2 of the indoor unit 101, the evaporator 3 returns the cooled air to the room, providing a comfortable indoor environment. Especially in the hot summer, the cooling effect of the evaporator can significantly reduce the indoor temperature and improve people's living comfort.

[0086] like Figure 7 and Figure 8 As shown, the indoor unit 101 also includes an electric heater 4, which is disposed within the receiving cavity 1a and partially surrounds the electric heater 4. The electric heater 4 has a first end 41 and a second end 42 that are opposite each other along the axial direction of the fan 2. The electric heater 4 is used to assist in heating when the air conditioner 100 is in heating mode, ensuring the heating capacity of the air conditioner 100 to reach the user's required temperature and improve user comfort.

[0087] like Figure 9 As shown, the indoor unit 101 also includes a first support member 5, which is disposed on one side along the axial direction of the fan 2 and connected to one end of the evaporator 3.

[0088] Combination Figure 6 and Figure 10 The indoor unit 101 also includes a second support member 6, which is arranged opposite to the first support member 5 along the axial direction of the fan 2, and the second support member 6 is connected to the other end of the evaporator 3.

[0089] Combination Figure 9 and Figure 11 The first support member 5 is provided with a mounting hole 5a, which penetrates the first support member 5 along the axial direction of the fan 2. The first end 41 of the electric heater 4 is inserted into the mounting hole 5a, which is used to fix the electric heater 4 radially along the fan 2. The second support member 6 is provided with a slot 61, the opening of which penetrates the first side wall 62 of the second support member 6 along the radial direction of the fan 2, so that the second end 42 of the electric heater 4 can be inserted into the slot 61 radially along the fan 2.

[0090] Thus, the electric heater 4 can be quickly installed through the mounting hole 5a of the first support member 5 and the slot 61 of the second support member 6. When installing the electric heater 4, first insert the first end 41 of the electric heater 4 into the mounting hole 5a, which limits the first end 41 of the electric heater 4 radially relative to the fan 2. Then, insert the second end 42 of the electric heater 4 radially into the slot 61 of the second support member 6, thus completing the installation of the electric heater 4. When disassembling the electric heater 4, first remove the second end 42 of the electric heater 4 from the slot 61 of the second support member 6. Then, the first end 41 of the electric heater 4 can be removed from the mounting hole 5a of the first support member 5 along the axial direction of the fan 2 to complete the disassembly of the electric heater 4. Compared with fixing the first end 41 and the second end 42 of the electric heater 4 to the first support member 5 and the second support member 6 by screws, this plug-in installation method makes the electric heater 4 more convenient and quick to install, which can improve assembly efficiency. At the same time, this plug-in installation method is easy to disassemble, which makes it easier to repair and replace the electric heater 4 when it needs to be repaired later, thus reducing the maintenance cost and time of the electric heater 4.

[0091] Optionally, the first support member 5 and the second support member 6 can be plate-shaped structures, that is, the first support member 5 and the second support member 6 can be mounting plates. When the first support member 5 and the second support member 6 are mounting plates, the mounting hole 5a and the slot 61 are set on the mounting plate. The plate-shaped support member can effectively save space in the cavity 1a inside the casing 1 due to its flat shape, making the layout of the indoor unit 101 more compact and reducing the axial dimension of the indoor unit 101 in the fan 101.

[0092] Of course, the first support member 5 and the second support member 6 can also be block structures, that is, the first support member 5 and the second support member 6 can be mounting blocks. When the first support member 5 and the second support member are mounting blocks, the block structure supports can provide a larger support area and stronger load-bearing capacity due to their volume and shape, which helps to ensure the stability of the evaporator 3 and the electric heater 4 during installation and operation, and prevent displacement or damage caused by vibration or external impact. Furthermore, the block structure can more effectively distribute the weight and stress from the evaporator 3 and the electric heater 4, reduce the possibility of single-point stress, and thus extend the service life of the entire unit.

[0093] Further, see Figures 10 to 12 The opening of the slot 61 has an elastic hook 611. The elastic hook 611 can undergo elastic deformation when the second end 42 of the electric heater 4 is engaged in the slot 61 to avoid the second end 42 of the electric heater 4. It can also prevent the second end 42 of the electric heater 4 from coming out of the opening of the slot 61 after the second end 42 of the electric heater 4 is engaged in the slot 61.

[0094] Among them, the elastic hook 611 refers to a hook that is elastic, that is, a hook that can undergo elastic deformation. After being deformed by force, it can return to its original state by its own elasticity.

[0095] Thus, the elastic hook 611 provided at the opening of the slot 61 can, on the one hand, undergo elastic deformation when the second end 42 of the electric heater 4 is engaged in the slot 61, thereby smoothly avoiding the second end 42 of the electric heater 4 and allowing it to enter the slot 61. Once the second end 42 of the electric heater 4 is fully engaged in the slot 61, the elastic hook 611 will return to its original shape and firmly hold the second end 42 of the electric heater 4, effectively preventing the second end 42 of the electric heater 4 from dislodging from the slot due to vibration or external force during operation, ensuring the stable installation of the electric heater 4. On the other hand, the design of the elastic hook 611 makes the installation of the electric heater 4 simpler and faster. Technicians do not need to use additional tools or fasteners; they only need to align the second end 42 of the electric heater 4 with the slot 61 and gently push it in to achieve a secure connection. This not only improves installation efficiency but also reduces installation costs. When the electric heater 4 needs maintenance or replacement, technicians can easily pull it out of the slot 61 by the elastic deformation of the elastic hook 611 without complicated disassembly work, which simplifies the maintenance process and reduces the risk of damage to the second support 6 due to improper disassembly.

[0096] It is understood that, in addition to providing an elastic hook 611 at the opening of the slot 61 as described in the above embodiments, a spring pin, an elastic baffle, an automatic rebound buckle, or other elastic components that can achieve fixation can also be provided at the opening of the slot 61. This embodiment does not specifically limit this.

[0097] Taking the automatic spring-loaded latch as an example, automatic spring-loaded latches typically have a more intuitive locking and unlocking mechanism, requiring no additional force or skill to operate. Furthermore, once locked, the automatic spring-loaded latch provides a stable hold, ensuring that the second end 42 of the electric heater 4 will not accidentally come loose due to vibration or external force, thus ensuring the normal operation of the electric heater. In addition, automatic spring-loaded latches are usually made of high-quality materials, such as metal or reinforced plastic, offering excellent durability and reliability. This means they can withstand more usage cycles and greater loads without damage or failure.

[0098] Optionally, combined Figure 6 and Figure 12 The elastic hook 611 includes a first hook 6112 and a second hook 6111, with the second hook 6111 and the first hook 6112 arranged opposite to each other along the radial direction of the fan 2.

[0099] The second end 42 of the electric heater 4 is provided with a first snap-fit ​​part 422 and a second snap-fit ​​part 421, and the second snap-fit ​​part 421 and the first snap-fit ​​part 422 are arranged opposite to each other along the radial direction of the fan 2. The second hook 6111 snaps into the second snap-fit ​​part 421, and the first hook 6112 snaps into the first snap-fit ​​part 422.

[0100] That is to say, one of the hooks of the elastic hook 611 is engaged with a corresponding engaging part of the second end 42 of the electric heater 4.

[0101] Thus, the double-clamping method, through the engagement of the second hook 6111 with the second clamping part 421 and the engagement of the first hook 6112 with the first clamping part 422, ensures a more secure installation of the electric heater 4, enhances the stability of the electric heater 4 during the operation of the fan 2, and reduces the risk of loosening or falling off due to vibration or external forces. Simultaneously, with the second hook 6111 and the first hook 6112 arranged radially opposite each other along the fan 2, the second end 42 of the electric heater 4 receives a more uniform force distribution during engagement. This helps reduce wear or damage to the second end 42 of the electric heater 4 due to uneven force distribution, thereby extending the service life of the electric heater.

[0102] It is understood that the second latching part 421 and the first latching part 422 can be a latch, a claw, or a latching protrusion, and this embodiment does not specifically limit them.

[0103] It should be noted that the elastic hook 611 does not only include two hooks, but may include multiple hooks. The multiple hooks can be engaged one-to-one with the multiple engaging parts of the second end 42 of the electric heater 4. This embodiment does not make specific limitations in this regard.

[0104] Furthermore, such as Figure 14 As shown, the first hook 6112 includes a first contact surface 6112a, which is used to abut against the first contact portion 422. The first contact surface 6112a is configured such that when the second end 42 of the electric heater 4 moves out of the opening of the slot 61, the first contact surface 6112a can drive the first hook 6112 to move away from the first contact portion 422 under the pressure of the first contact portion 422.

[0105] In this way, the first engaging surface 6112a can move the first hook 6112 away from the first engaging portion 422 under the pressure of the first engaging part 422. This achieves flexibility and releasability of the connection. When it is necessary to disassemble or replace the electric heater 4, the user can release the engagement through a simple operation (such as pushing or pulling). Furthermore, when the first engaging part 422 moves out of the opening of the slot 61, the first engaging surface 6111a can gradually release stress, rather than breaking suddenly like a rigid connection. This helps to extend the service life of the first hook 6112 and reduce damage caused by stress concentration.

[0106] The second hook 6111 includes a second contact surface 6111a, which is used to abut against the second contact portion 421. The second contact surface 6111a is configured to restrict the second contact portion 421 from moving out of the opening of the slot 61.

[0107] In this way, the second snap-fit ​​surface 6111a is configured to restrict the movement of the second snap-fit ​​portion 421 outward from the opening of the slot 61. This ensures that the electric heater 4 will not easily fall off due to external force or vibration after snapping, thus improving the stability and reliability of the snap-fit. Since the second snap-fit ​​surface 6111a can directly abut against and lock the second snap-fit ​​portion 421, this simplifies the installation process, reduces installation costs, and improves installation efficiency.

[0108] Optionally, such as Figure 14 and Figure 15 As shown, the second hook 6111 includes a second connecting arm 611b and a second protrusion 611a connected to each other. The second protrusion 611a includes a second engaging surface 6111a for abutting against the second engaging portion 421. The second connecting arm 611b includes a second abutting surface 6111b for abutting against the second engaging portion 421. The second engaging surface 6111a and the second abutting surface 6111b are perpendicular. That is to say, the included angle α between the second engaging surface 6111a and the second abutting surface 6111b is a right angle.

[0109] It is worth noting that the perpendicularity between the second contact surface 6111a and the second abutment surface 6111b does not simply mean that the included angle α is 90 degrees. In fact, there is an error of 3-4 degrees in the included angle α between the second contact surface 6111a and the second abutment surface 6111b, that is, the included angle α between the second contact surface 6111a and the second abutment surface 6111b is between 86 degrees and 94 degrees.

[0110] Optionally, combined Figure 14 and Figure 15 The first hook 6112 includes a first connecting arm 611d and a first protrusion 611c connected to each other. The first protrusion 611c includes a first engaging surface 6112a for abutting against the first engaging part 422. The first connecting arm 611d includes a first abutting surface 6112b for abutting against the first engaging part 422. The included angle β between the first engaging surface 6112a and the first abutting surface 6112b is an obtuse angle.

[0111] When the included angle α between the second abutting surface 6111b of the second connecting arm 611b and the second locking surface 6111a of the second protrusion 611a, and the included angle β between the first abutting surface 6112b of the first connecting arm 611d and the first locking surface 6112a of the first protrusion 611c are acute angles, that is, when the included angle α between the second abutting surface 6111b and the second locking surface 6111a is less than 86 degrees, and the included angle β between the first locking surface 6112a and the first abutting surface 6112b is less than 90 degrees, the stress on the hook will be concentrated at the connection between the abutting surface and the locking surface, which cannot guarantee that the hook can be used for a long time. When the angle α between the second abutting surface 6111b of the second connecting arm 611b and the second engaging surface 6111a of the second protrusion 611a is obtuse (i.e., the angle α is greater than 94 degrees), the second end 42 of the electric heater 4 may come off along the second engaging surface 6111a under gravity, which cannot guarantee the stable installation of the electric heater 4. When the angle β between the first abutting surface 6112b of the first connecting arm 611d and the first engaging surface 6112a of the first protrusion 611c is right-angled, the deformation space of the first hook 6112 under stress is reduced. This means that when the first hook 6112 is subjected to external force, its ability to absorb and disperse stress will be reduced, thereby reducing cushioning and elasticity. Meanwhile, when installing the second end 42 of the electric heater 4, the right-angle structure makes it difficult to insert the first snap-fit ​​part 422 into the first snap hook 6112 along the radial direction of the fan 2, which increases the assembly difficulty of the first snap hook 6112.

[0112] Thus, the perpendicularity between the second abutting surface 6111b of the second connecting arm 611b and the second engaging surface 6111a of the second protrusion 611a means that the included angle α between the second abutting surface 6111b and the second engaging surface 6111a is 90 degrees, i.e., the second hook 6111 is a right-angle structure. This ensures that the second engaging part 421 has the maximum contact area with the second hook 6111 when engaging, thereby providing a stronger engaging force. When the second hook 6111 abuts against the second engaging part 421, this right-angle structure can prevent the second hook 6111 from engaging. When subjected to force, 111 rotates or slides, further enhancing the stability of the connection. Moreover, such a right-angle structure is easy to install and disassemble. Simply align the second engaging surface 6111a and the second abutting surface 6111b of the second hook 6111 with the corresponding parts of the second engaging portion 421, and then apply appropriate force to achieve connection or separation. During installation, the right-angle structure provides a clear positioning point, which helps to ensure that the second hook 6111 can be accurately aligned with the second engaging portion 421 during installation, thereby improving the accuracy and reliability of the engagement.

[0113] The obtuse angle β between the first abutment surface 6112b of the first connecting arm 611d and the first engaging surface 6112a of the first protrusion 611c gives the first hook 6112 a certain degree of elasticity. When the first hook 6112 is subjected to external force, this obtuse angle structure allows the first hook 6112 to deform to a certain extent, thereby absorbing and dispersing the external force and playing a buffering role. Furthermore, the obtuse angle design helps to reduce stress concentration on the first hook 6112, allowing for a more even distribution of stress when subjected to external force, thus reducing the risk of damage to the first hook 6112 due to stress concentration. This enables the first hook 6112 to better resist fatigue and wear during long-term use, contributing to improved durability and service life of the connection. Furthermore, the obtuse angle design between the first contact surface 6112a and the first abutment surface 6112b of the first hook 6112 provides a certain guiding effect when the first contact part 422 is inserted into the first hook 6112, making the installation smoother. When it is necessary to disassemble the electric heater 4, the first contact surface is inclined along the opening direction of the slot 61, making it easier for the first contact part 422 of the electric heater 4 to come out in the opposite direction along the opening of the slot 61, which facilitates the disassembly of the electric heater 4.

[0114] It should be noted that, in addition to the configuration described in the above embodiments, the second snap-fit ​​part 421 may be inclined with the snap-fit ​​surface for snapping with the second snap hook 6111 relative to the extension direction of the second snap hook 6111, and the snap-fit ​​surface for snapping with the first snap-fit ​​part 422 may be perpendicular to the extension direction of the first snap hook 6112. This embodiment does not specifically limit this.

[0115] In some embodiments, such as Figure 14As shown, the second support member 6 also includes a blocking part 63, which is located on the side of the slot 61 away from the electric heater 4. The blocking part 63 abuts against the second end 42 of the electric heater 4 to limit the electric heater 4 along the axial direction of the fan 2.

[0116] That is to say, after the second end 42 of the electric heater 4 is inserted into the slot 61 of the second support member 6 along the radial direction of the fan 2, the blocking part 63 of the second support member 6 can limit the electric heater 4 in the axial direction of the fan 2.

[0117] In this way, the blocking part 63 effectively restricts the axial movement of the electric heater 4 in the fan 2, which allows the electric heater 4 to maintain a more stable position during operation, reducing axial displacement caused by vibration or external forces, thereby improving the stability and reliability of the entire air conditioner 100. In extreme cases, such as encountering strong vibration or external impact, the electric heater 4 may detach from the slot 61. Due to the presence of the blocking part 63, the electric heater 4 is effectively blocked in the axial direction, thus greatly reducing the risk of detachment.

[0118] Optionally, the blocking portion 63 of the second support member 6 is a baffle, and the extending direction of the baffle is perpendicular to the axis of the fan 2. That is to say, the end face of the second end 42 of the electric heater 4 abuts against the baffle.

[0119] In this way, the baffle's extension direction is perpendicular to the axis of the fan 2, which ensures that the contact area between the baffle and the second end 42 of the electric heater 4 is maximized, thereby providing a stronger limiting effect on the electric heater 4 in the axis of the fan 2, so as to further ensure the stable installation of the electric heater 4.

[0120] It is understood that the blocking part 63 can be a baffle, or it can be an elastic buckle, a limiting pin, or other components that can limit the electric heater 4 in the axial direction of the fan 2. This embodiment does not specifically limit it.

[0121] Optionally, such as Figure 17 As shown, the blocking part 63 has a reinforcing rib 631 on the side opposite to the electric heater 4. This reinforcement rib 631 significantly enhances the structural strength of the blocking part 63, enabling it to better withstand the pressure from the electric heater 4 and the vibration and impact forces generated during the operation of the fan 2. Furthermore, the reinforcement rib 631 also enhances the stability of the blocking part 63 during installation. When the electric heater 4 is installed into the slot 61, the additional support provided by the reinforcement rib 631 allows the blocking part 63 to more firmly fix the electric heater 4, preventing displacement or detachment during operation.

[0122] In some embodiments, combined with Figure 6 , Figure 16 and Figure 17 The indoor unit 101 also includes a motor protection component 7, which is located outside the opening of the slot 61 and abuts against the first side wall 62 of the second support component 6. By positioning the motor protection component 7 outside the opening of the slot 61 and abutting against the first side wall 62 of the second support component 6, the second end 42 of the electric heater 4, facing the fan 2, contacts the motor protection component 7. This allows the motor protection component 7 to further limit the electric heater 4 radially relative to the fan 2, preventing the second end 42 of the electric heater 4 from detaching from the slot.

[0123] It is understandable that the motor protection component 7 is located outside the opening of the slot 61 and is used to isolate the motor. That is, the motor is set on the side of the motor protection component 7 away from the slot 61. The motor protection component 7, together with the motor fixing structure, limits the motor from multiple directions under the joint action of the motor protection component 7 and the motor fixing structure, ensuring the positional stability of the motor after installation and reducing the displacement of the motor caused by vibration or other external forces during operation. At the same time, the motor protection component 7 separates the motor from the electric heater 4, avoiding direct contact and collision between the motor and the electric heater 4.

[0124] Furthermore, combined Figure 11 and Figure 17 The motor protection component 7 includes a first outer contour surface 7a for abutting against the first sidewall 62 of the second support component 6, and the first sidewall 62 of the second support component 6 is adapted to the first outer contour surface 7a.

[0125] The adaptation of the first sidewall 62 of the second support member 6 to the first outer contour surface 7a refers to the shape adaptation, size adaptation and structural adaptation between the first sidewall 62 and the first outer contour surface 7a.

[0126] Shape fit means that the first sidewall 62 and the first outer contour surface 7a can perfectly match in appearance without gaps or misalignment. The shape of the first outer contour surface 7a should match the shape of the first sidewall 62. If the first sidewall 62 is flat, then the first outer contour surface 7a should also be flat and of similar size. If the first sidewall 62 has a certain curve or angle, the first outer contour surface 7a should also have a corresponding curve or angle to ensure that the two can fit tightly together.

[0127] Size fit means that the first sidewall 62 and the first outer contour surface 7a can match each other in size, neither too tight nor too loose. If the size of the first outer contour surface 7a is too large, it may cause difficulty in installation or create excessive gaps; if the size is too small, it may result in an overly tight assembly, leading to component damage or assembly difficulties.

[0128] Structural adaptation refers to the structural coordination between the first sidewall 62 and the first outer contour surface 7a to jointly achieve a specific function. The structural relationship between the first outer contour surface 7a and the first sidewall 62 is also crucial in the assembly of the motor protection component 7 and the second support component 6. For example, if the first sidewall 62 has a specific connection structure (such as a threaded hole or locating pin), then the first outer contour surface 7a should also have a corresponding connection structure (such as threads or locating grooves) to ensure a secure connection between the two.

[0129] In this way, by adapting the first outer contour surface 7a of the motor guard 7 to the first side wall 62, it is ensured that the motor guard 7 can be tightly attached to the first side wall 62 during installation, thereby ensuring that the motor guard 7 can be tightly attached to the second end 42 of the electric heater 4, and further ensuring the stable installation of the second end 42 of the electric heater 4 in the radial direction of the fan 2.

[0130] In some embodiments, combined with Figure 5 and Figure 13 There is a preset gap between the peripheral wall of the first end 41 of the electric heater 4 and the wall of the mounting hole 5a of the first support member 5. In this way, the preset gap allows the first end 41 of the electric heater 4 to have a certain adjustment space during installation, which facilitates the installer to make fine adjustments during the installation process to ensure that the electric heater 4 can be installed correctly and stably in the predetermined position.

[0131] Optionally, such as Figure 8 As shown, the cross-sectional dimension of the first end 41 of the electric heater 4 gradually decreases along the direction away from the second end 42 of the electric heater 4. That is to say, the first end 41 of the electric heater 4 is inclined along the direction away from the second end 42. Therefore, when the first end 41 of the electric heater 4 is installed into the mounting hole 5a, the inclined first end 41 has a certain guiding effect, which makes it easier for the first end 41 of the electric heater 4 to be inserted into the mounting hole 5a. In addition, the inclined first end 41 also helps to prevent the first end 41 from rubbing against the mounting hole 5a during the insertion process, thus preventing damage to the structure of the first end 41 of the electric heater 4.

[0132] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
