The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0037] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0038] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, X and / or Y can represent the following three situations: X exists alone, X and Y exist simultaneously, and Y exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0040] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0041] See also Figure 1-Figure 3 The present application provides an air conditioner 100, which includes a housing 10, an electronic control component 20, a refrigerant pipe 31, a partition 40 and a shielding member 50; the electronic control component 20 is arranged in the housing 10; the refrigerant pipe 31 is arranged in the housing 10, and the refrigerant pipe 31 is spaced apart from the electronic control component 20; the partition 40 is arranged between the electronic control component 20 and the refrigerant pipe 31, and the partition 40 is provided with a through hole 41, which passes through the partition 40 from the electronic control component 20 to the refrigerant pipe 31; the shielding member 50 is arranged between the through hole 41 and part of the refrigerant pipe 31, and shields the through hole 41 along the depth direction of the through hole 41.

[0042] Specifically, the electronic control assembly 20 is composed of interconnected electronic components within the air conditioner 100 and is used to control the operating status of the air conditioner 100. The electronic control assembly 20 includes, for example, circuit boards, capacitors, relays, sensors, etc., and is connected via wires to receive commands from the user interface and send control signals to other parts of the air conditioner 100. The control signals can include, for example, start, stop, temperature adjustment, and fan speed control.

[0043] Air conditioner 100 also includes a heat exchanger 30, which is composed of a series of coiled or tightly arranged refrigerant tubes 31, with refrigerant flowing within them. Refrigerant, also known as refrigerant, is a working fluid used in air conditioning and refrigeration systems to transfer heat energy and produce a cooling effect. The refrigerant achieves heat transfer through evaporation and condensation. For example, the refrigerant may be R454B, a mildly flammable hydrofluoroolefin-based refrigerant. The refrigerant in the refrigerant tubes 31 of the heat exchanger 30 absorbs heat from the ambient environment outside the air conditioner 100 and evaporates into a gaseous state, thereby reducing the ambient temperature outside the air conditioner 100.

[0044] The refrigerant pipe 31 is spaced apart from the electronic control assembly 20 to prevent electromagnetic interference between the wires of the refrigerant pipe 31 and the electronic control assembly 20 from being too close. The spacing is set to be greater than 5 cm, for example, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, or 19 cm.

[0045] The partition 40 is arranged between the electronic control component 20 and the refrigerant pipe 31 to separate the electronic control component 20 and the refrigerant pipe 31. It is used to prevent the refrigerant in the refrigerant pipe 31 from leaking and splashing onto the electronic control component 20 to damage the electronic control component 20, and when the refrigerant is a flammable substance such as R454B, it prevents the refrigerant concentration near the electronic control component 20 from being too high and causing an explosion due to the electric spark of the electronic control component 20.

[0046] Partition 40 is provided with a through hole 41 extending from electronic control assembly 20 toward refrigerant pipe 31. Through hole 41 is designed to ensure a more standardized and orderly routing of the electronic control assembly 20 within air conditioner 100. The clear routing path and fixed position of through hole 41 prevent the random insertion and disorganization of wires, and ensure that the wires will not be worn or broken due to external forces or internal movement.

[0047] Even if a partition 40 is provided between the electronic control component 20 and the refrigerant pipe 31 , there is still a risk that when refrigerant leaks, a large amount of refrigerant may enter the vicinity of the electronic control component 20 through the through hole 41 , resulting in excessive refrigerant concentration and explosion caused by electric sparks from the electronic control component 20 .

[0048] To address this issue, the present embodiment incorporates a shielding member 50. This shielding member 50 shields the through-hole 41 of the partition 40, preventing refrigerant from directly entering the area around the electronic control assembly 20. By reducing the diffusion rate and range of refrigerant leakage, the shielding member 50 helps reduce the refrigerant concentration near the electronic control assembly 20. The shielding member 50 is a plate-shaped structure with multiple screw holes, allowing it to be attached to the housing 10 of the air conditioner 100 using stainless steel screws. The shielding member 50 is constructed from a corrosion-resistant and refrigerant-resistant material, such as stainless steel, aluminum alloy, or a specific plastic material, to withstand refrigerant erosion and the pressure generated by leakage. The shielding member 50 is secured between the electronic control assembly 20 and the refrigerant pipe 31. The refrigerant pipe 31 is divided into a first refrigerant pipe 311 and a second refrigerant pipe 312 based on its position relative to the through-hole 41. The portion of the refrigerant pipe 31 facing the through-hole 41 is the first refrigerant pipe 311, while the remaining portion is the second refrigerant pipe 312. Shielding member 50 is disposed between via 41 and first refrigerant pipe 311 and blocks via 41 along its depth. This prevents refrigerant from directly entering via 41 in the event of a refrigerant pipe 31 leak, thereby preventing a large amount of refrigerant from entering the vicinity of electronic control assembly 20 in a short period of time. Shielding member 50 effectively reduces the concentration of refrigerant near electronic control assembly 20 in the event of a refrigerant leak, preventing it from causing an explosion.

[0049] In the air conditioner 100 of the embodiment of the present application, a shielding member 50 is provided between the through-hole 41 and part of the refrigerant pipe 31 to prevent the refrigerant pipe 31 from leaking and directly spraying into the through-hole 41, thereby preventing a large amount of refrigerant from entering the vicinity of the electronic control component 20 from the through-hole in a short period of time, resulting in excessive concentration and causing an explosion caused by the electric spark of the electronic control component 20.

[0050] See also Figure 3 In some embodiments, the shielding member 50 includes a baffle 51 and a shielding edge 52 connected to the edge of the baffle 51. The baffle 51 is located between the through hole 41 and the refrigerant pipe 31, and shields the through hole 41 along the depth direction of the through hole 41. The shielding edge 52 and the baffle 51 form an accommodating space, and part of the refrigerant pipe 31 is partially accommodated in the accommodating space.

[0051] Specifically, the baffle 51 is used to block the through-hole 41, reducing the horizontal leakage range and leakage rate of the refrigerant. When the leaked refrigerant reaches the baffle 51, it will adhere to the baffle 51 or turn to spread in the vertical direction. The shielding edge 52 is the portion of the shielding member 50 that is connected to the edge of the baffle 51 and continues to extend toward the refrigerant pipe 31. When the leaked refrigerant reaches the baffle 51, the shielding edge 52 blocks the shielding member 50 from spreading upward, preventing the refrigerant from bypassing the baffle 51 from above and entering the through-hole 41. The shielding edge 52 can only spread downward, further enhancing the shielding effect of the baffle 51. In addition, the shielding edge 52 and the baffle 51 together enclose a storage space. The storage space is a semi-enclosed area for accommodating the first refrigerant pipe 311, which can play a certain role in protecting the refrigerant pipe 31 and minimize the space required for installing the shielding member 50.

[0052] See also Figure 2 and Figure 3 In some embodiments, the housing 10 includes a side panel 11 and a mounting plate 12 connected to the side panel 11, the partition 40 is mounted on the mounting plate 12, and the shielding member 50 also includes a flange 53 connected to the baffle 51. The shielding member 50 is mounted on the mounting plate 12 through the flange 53, and the flange 53 is connected to a different edge of the baffle 51 from the shielding edge 52.

[0053] Specifically, side panels 11 are a key component of the air conditioner's outer casing 10. Side panels 11, which may be formed from multiple metal plates, possess a certain degree of strength and durability. They surround the air conditioner 100, forming a closed or semi-enclosed space to protect the electronic control unit 20 and refrigerant system within the air conditioner 100 from external interference. Mounting plate 12 is a flat plate-shaped member connected to side panels 11. Located within outer casing 10, it secures and supports key components such as the partition 40, electronic control unit 20, and heat exchanger 30.

[0054] The flange 53 is the portion of the shielding member 50 that is connected to the other edge of the baffle 51 and continues to extend toward the electronic control component 20 . It is designed with multiple screw holes, and the shielding member 50 can be fixed to the mounting plate 12 by screws.

[0055] See also Figure 3 and Figure 5 In some embodiments, the air conditioner 100 includes a wire passing element 60 passing through the through hole 41 , and the wire passing element 60 is used for allowing the wire to pass through the partition 40 .

[0056] The wire-passing element 60 is a hollow tubular structure with a diameter slightly smaller than the diameter of the through-hole 41. For example, if the diameter of the through-hole 41 is 20 mm, the diameter of the wire-passing element 60 can be 18 mm or 19 mm. The wire-passing element 60 is disposed in the through-hole 41 to allow the wires of the power control assembly 20 to pass through. It is used to manage the wiring of the internal circuits of the air conditioner 100, ensuring that the wires pass neatly and orderly through the partition 40. It also provides additional protection and sealing to prevent the wires from loosening, wearing, or being interfered with by the external environment.

[0057] See also Figure 3 and Figure 5 In some embodiments, the wire-passing element 60 includes a wire-passing barrel 61 and a sealing ring 62 sleeved on the wire-passing barrel 61 . The wire-passing barrel 61 is passed through the through hole 41 , and the sealing ring 62 seals the gap between the wire-passing barrel 61 and the hole wall of the through hole 41 .

[0058] The wire barrel 61 is the main body of the wire passing element 60, which is a hollow tubular structure. The wire barrel 61 is passed through the through hole 41. The material of the wire barrel 61 is selected to have a certain strength and toughness, such as metal or plastic, to ensure that it can withstand the weight and tension of the wire for a long time and maintain the stability of the structure. The sealing ring 62 is sleeved on the wire barrel 61 and is located between the wire barrel 61 and the hole wall of the through hole 41. Its main function is to seal the gap between the two. The sealing ring 62 can be made of an elastic material, such as rubber or silicone, to ensure that it can fit tightly on the wire barrel 61 and the hole wall, to prevent gaps between the wire barrel and the hole wall during the wire passing process, and to prevent refrigerant, dust, moisture or other external contaminants from entering the through hole 41.

[0059] See also Figure 5 In some embodiments, the wire passing barrel 61 has an opening, and the wire passing element 60 includes a wire passing sleeve 63 arranged at the opening. The wire passing sleeve 63 includes a ring 631 and a plurality of closing pieces 632. The ring 631 is sleeved on the wire passing barrel 61, and one side edge of the closing piece 632 is connected to the ring 631. The closing piece 632 can be folded and deformed under the action of external force. The plurality of closing pieces 632 are arranged along the circumference of the opening and jointly close the opening.

[0060] The wire sleeve 63 is an additional component provided at the opening of the wire barrel 61, and is mainly used to further protect and fix the wires passed through the wire barrel 61. The design of the wire sleeve 63 needs to take into account the number and size of the wires to ensure that it can accommodate all the wires that need to be passed through and keep them neat and stable. The ring 631 is the main part of the wire sleeve 63 and is an annular structure. The diameter of the ring 631 matches the diameter of the wire barrel 61 to ensure that it can be firmly sleeved on the opening of the wire barrel 61. For example, if the opening diameter of the wire barrel 61 is 20 mm, the diameter of the ring 631 can be 20.5 mm. The closing piece 632 can be a rubber sheet or a plastic sheet. One side edge of the closing piece 632 is connected to the ring 631 and can be folded and deformed under the action of external force to facilitate the passage of the wire. The design of the closing piece 632 takes into account the wire passing requirements and sealing effect to ensure that the wire can be passed through smoothly and kept in the required position while preventing foreign objects from entering. The sealing pieces 632 may be shaped like a sector, and there may be multiple of them, arranged along the circumference of the opening of the wire barrel 61, and together close the opening of the wire barrel 61. For example, the sealing pieces 632 may be shaped like a sector with a 90-degree angle, with an arc edge connected to the collar 631. The number of sealing pieces 632 may be four, ensuring that the opening of the wire barrel 61 is fully sealed.

[0061] See also Figure 6 In some embodiments, the wire-passing element 60 can also be another structure, and a flexible tube 64 is provided at at least one axial end of the wire-passing barrel 61, and the flexible tube 64 can be tightened under the action of a tightening belt. A flexible tube 64 can be provided at one end of the wire-passing barrel 61 in the axial direction, or at both ends. The flexible tube 64 has a certain elasticity and can be tightened by a tightening belt. A tightening belt is an elastic or rigid strip material commonly used to fix, protect and organize cables. In the optimized design of the internal circuit routing of the air conditioner 100, a tightening belt is used to tighten the flexible tube 64 to ensure that the wire can be firmly maintained in the wire-passing barrel 61 to prevent it from loosening or shifting.

[0062] See also Figure 2 and Figure 7 In some embodiments, the via 41 is disposed on the top of the partition 40 .

[0063] The placement of the via 41 at the top of the partition 40 is based on the fact that the density of the refrigerant is greater than that of air. If the refrigerant leaks, it will sink due to gravity. Placing the via 41 at the top of the partition 40 reduces the amount of refrigerant entering the electronic control assembly 20 area through the via 41.

[0064] See also Figure 2 and Figure 8In some embodiments, the air conditioner 100 further includes a fan 70. The side panel 11 and the mounting plate 12 together form a first chamber 13 and a second chamber 14. The mounting plate 12 separates the first chamber 13 from the second chamber 14. The mounting plate 12 is provided with a vent 80 connecting the first chamber 13 and the second chamber 14. The electronic control component 20 is disposed in the first chamber 13; the fan 70 is disposed in the second chamber 14 and is configured to create airflow between the first chamber 13 and the second chamber 14 through the vent 80.

[0065] In the air conditioner 100 of the embodiment of the present application, vents 80 are provided on the mounting plate 12, connecting the first chamber 13 and the second chamber 14, thereby forming an effective heat dissipation channel. When heat accumulates from the operation of the electronic control component 20 in the first chamber 13, this heat is transferred to the second chamber 14 through this heat dissipation channel. The heat is then dissipated to the external environment by the fan 70 in the second chamber 14, thereby ensuring the normal operation of the electronic control component 20 and extending its service life.

[0066] Specifically, the mounting plate 12 divides the interior of the housing 10 into a first chamber 13 and a second chamber 14. The first chamber 13 is primarily used to house electronic control components 20, such as circuit boards, capacitors, and relays. These components generate a certain amount of heat during operation of the air conditioner 100, requiring effective heat dissipation. The second chamber 14 is primarily used to house ventilation equipment such as the fan 70.

[0067] The first chamber 13 and the second chamber 14 are interconnected through the vents 80 provided on the mounting plate 12. The fan 70 generates airflow by rotating, which can form air flow between the two chambers, thereby achieving heat dissipation of the electronic control component 20. The vents 80 are one or more openings provided on the mounting plate 12. The vents 80 allow airflow to flow freely between the two chambers. The size and position of the vents 80 need to be reasonably designed according to the heat dissipation requirements of the electronic control component 20 and the performance of the fan 70 to ensure that the heat dissipation effect is optimal. The fan 70 is provided in the second chamber 14 and generates airflow by rotating, which drives the air to circulate between the two chambers. The performance parameters of the fan 70, such as the rotation speed and air volume, need to be selected and adjusted according to the heat dissipation requirements of the electronic control component 20 and the overall design of the air conditioner 100.

[0068] The airflow generated by fan 70 forms a circulating flow between the two chambers, effectively removing heat generated by electronic control assembly 20 and dissipating it to the external environment, thereby ensuring the normal operation and extending the service life of electronic control assembly 20. In addition, if refrigerant accidentally leaks and enters first chamber 13, the airflow generated by fan 70 can transport the refrigerant into second chamber 14, reducing the refrigerant concentration in first chamber 13 and thereby reducing safety hazards such as fire or explosion caused by refrigerant leakage.

[0069] In some embodiments, ventilation openings 80 are provided on the bottom and / or top of the mounting plate 12 .

[0070] The ventilation holes can be located, for example, at the bottom or top of the mounting plate 12, or at both the bottom and top. All of these arrangements effectively remove heat generated by the electronic control assembly 20, lowering its operating temperature and thereby improving the operating efficiency and stability of the air conditioner 100. Placing the ventilation holes at the bottom of the mounting plate 12 facilitates the airflow generated by the fan 70 to blow dust deposited at the bottom of the first chamber 13 into the second chamber 14, where it is then discharged outside the air conditioner 100 through the fan 70 in the second chamber 14. Furthermore, because the refrigerant has a higher density than air, it will sink to the bottom of the first chamber 13 upon entering, thus effectively reducing its concentration. Placing the ventilation holes at the top of the mounting plate 12 facilitates the immediate discharge of refrigerant leaking from the top via 41, preventing the refrigerant from contacting and interfering with the electronic control assembly 20. The ventilation holes are arranged at the top and bottom of the mounting plate 12 at the same time, which is more conducive to the air circulation inside the air conditioner 100, making the inside of the air conditioner 100 cleaner and preventing local overheating inside the air conditioner 100. The air can enter from the bottom and be discharged from the top, or it can enter from the top and be discharged from the bottom, which is related to the flow direction of the airflow of the fan 70.

[0071] In some embodiments, there are multiple vents 80 located at the bottom and / or top of the mounting plate 12 , and the multiple vents 80 are spaced apart along the width direction of the mounting plate 12 .

[0072] The number of ventilation openings 80 at the bottom and / or top of the mounting plate 12 is multiple. For example, two ventilation openings 80 may be provided at the bottom of the mounting plate 12, two ventilation openings 80 may be provided at the top of the mounting plate 12, or four ventilation openings 80 may be provided at both the bottom and the top of the mounting plate 12, and the multiple ventilation openings 80 are arranged at intervals along the width direction of the mounting plate 12. The multiple ventilation openings 80 are arranged at intervals along the width direction, which can more effectively utilize the space of the mounting plate 12 and increase the area for air circulation, which helps to accelerate the circulation of air inside the air conditioner 100, improve the heat dissipation efficiency, and ensure that heat-generating components such as the electronic control assembly 20 are fully cooled. In addition, the ventilation openings 80 can be evenly distributed along the width direction of the mounting plate 12 to ensure that air can evenly enter and exit the interior of the air conditioner 100.

[0073] By rationally designing the number and layout of the vents 80 , the airflow distribution inside the air conditioner 100 can be optimized, which helps to avoid local overheating or overcooling, ensures a more uniform temperature distribution inside the air conditioner 100, and thus improves the overall operating efficiency and stability of the air conditioner 100.

[0074] Furthermore, in actual design, the size and number of the vents 80 at the bottom and / or top of the mounting plate 12 need to be comprehensively considered based on factors such as the specific model, power, and operating environment of the air conditioner 100. Excessively large vents 80 may result in increased noise and reduced energy efficiency, while excessively small vents 80 may not meet heat dissipation requirements. The design of the vents 80 must also take safety performance into consideration. For example, in the event of a refrigerant leak, the vents 80 can serve as channels for the discharge of refrigerant gas. Therefore, it is necessary to ensure that the size and location of the vents 80 meet the requirements for safe discharge.

[0075] See also Figure 2 and Figure 9 In some embodiments, a folding piece 81 is provided at the edge of the vent 80 , and the folding piece 81 covers part of the vent 80 along the projection on the mounting plate 12 .

[0076] By providing a folding piece 81 at the edge of the vent 80, the risk of dust and other foreign matter entering the first chamber 13 can be effectively reduced. This design not only enhances the sealing of the first chamber 13, but also improves its overall protective capabilities. The folding piece 81 partially covers the vent 80 along the projection on the mounting plate 12. This means that when outside air enters the first chamber 13 through the vent 80, the folding piece 81 acts as a barrier, blocking most dust and foreign matter. At the same time, the folding piece 81 also has a certain degree of elasticity, which can adapt to particles of different sizes, further improving the protective effect.

[0077] Furthermore, the provision of the flap 81 does not affect the normal ventilation function of the vent 80. Because the flap 81 only partially covers the vent 80, air can still flow freely into and out of the electrical control room. This ensures that the first chamber 13 remains ventilated while preventing the intrusion of dust and foreign matter.

[0078] In practice, the flap 81 can be manufactured using a variety of materials and processes. For example, it can be made of metal, plastic, or rubber to suit different usage environments and requirements. Furthermore, the shape and size of the flap 81 can be customized based on the size and shape of the vent 80 to ensure optimal protection.

[0079] See also Figure 1-Figure 3 In certain embodiments, an air conditioner 100 includes a housing 10, an electronic control assembly 20, and a sensor 90. The housing 10 includes a base plate 15 and a panel 16 connected to the base plate 15, and the panel 16 is detachably connected to the base plate 15. The electronic control assembly 20 is disposed within the housing 10. The sensor 90 is configured to detect the refrigerant concentration. The sensor 90 is disposed within the housing 10 and adjacent to the base plate 15, and is positioned opposite the panel 16.

[0080] In the air conditioner 100 of the embodiment of the present application, by arranging the sensor 90 at a position near the bottom plate 15 in the casing 10, the sensor 90 can more easily detect the refrigerant gas accumulated at the bottom due to its density being greater than that of air, thereby improving the accuracy and sensitivity of refrigerant detection, and preventing the refrigerant gas from accumulating at too high a concentration near the electronic control component 20, thereby reducing the risk of explosion. In addition, the sensor 90 and the panel 16 are arranged relative to each other, and the panel 16 is detachable, which is beneficial to the maintenance of the sensor 90.

[0081] Specifically, the housing 10 includes a base plate 15 and a panel 16 connected to the base plate. The base plate 15 is a support platform for the internal components of the air conditioner 100 and is made of a strong and durable material, such as metal or reinforced plastic, to ensure that it can withstand various mechanical stresses and thermal stresses during the operation of the air conditioner. The panel 16 is the outer protective shell of the air conditioner 100, which is used to protect the components inside the air conditioner 100 from dust, moisture and other potential contaminants. The base plate 15 is also equipped with mounting holes, such as screw holes or clips, through which the panel 16 is detachably connected to the base plate 15. When the air conditioner 100 fails or requires maintenance or replacement of internal equipment, the panel 16 can be removed to facilitate direct inspection, repair or replacement of the electronic control components 20 or other equipment inside the air conditioner 100.

[0082] The sensor 90 collects gas samples from the air conditioner through its internal collection system or sensor chip. The sensor 90 is divided into various types according to the different working principles of refrigerant gas detection. For example, the sensor based on the principle of micro-electro-mechanical systems (MEMS) has a semiconductor silicon-based resistive sensor chip inside that changes its resistance value according to the concentration of the refrigerant gas, such as R454B gas, thereby detecting the gas concentration. The sensor 90 can also be a sensor based on non-dispersive infrared technology (NDIR, Non-Dispersive InfraRed) technology. They use the principle of infrared light absorption to calculate the gas concentration by measuring the change in the intensity of infrared light before and after passing through a sample containing refrigerant gas. The sensor 90 is set in the housing 10 and is set close to the bottom plate 15. This is because the density of refrigerant is greater than that of air. When the refrigerant leaks, it is more likely to sink and accumulate near the bottom plate 15. Placing the sensor 90 close to the bottom 15 can improve the sensitivity and accuracy of the refrigerant detection of the sensor 90. The sensor 90 is arranged opposite to the panel 16. When the panel 16 is removed, the exposed sensor 90 can be directly seen, which is convenient for maintenance.

[0083] In some embodiments, the distance between the sensor 90 and the base plate 15 is less than or equal to 110 mm.

[0084] The distance between sensor 90 and base plate 15 can be, for example, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, or 110 mm. After a refrigerant, such as R454B, leaks, it tends to accumulate in low areas or near base plate 15 due to its greater density than air. Mounting sensor 90 no more than 110 mm from base plate 15 ensures that sensor 90 is in direct contact with any refrigerant gas that may have accumulated, thereby improving the accuracy and sensitivity of leak detection. Furthermore, the space inside air conditioner 100 is limited, with many electronic components located in electronic control assembly 20 and few near base plate 15. Mounting sensor 90 closer to base plate 15 makes full use of the limited space and avoids interference with other components. Furthermore, when sensor 90 needs to be maintained or replaced, technicians can access and operate it relatively easily without the need for complex disassembly.

[0085] In some embodiments, the mounting plate 12 abuts against the bottom plate 15 and is connected to the side plate 11 , and the electronic control component 20 and the sensor 90 are both mounted on the mounting plate 12 ; the sensor 90 is located on the side of the mounting plate 12 away from the heat exchanger 30 .

[0086] The mounting plate 12 abuts against the bottom plate 15 and is connected to the side plate 11. This layout not only enhances the stability of the mounting plate 12, but also allows the electronic control components 20 and sensors 90 on the mounting plate 12 to be more conveniently connected to power lines and signal lines.

[0087] Sensor 90 is located on the side of mounting plate 12 away from heat exchanger 30. If sensor 90 is located on the side close to heat exchanger 30, it may be affected by the normal operation of the refrigerant flow in refrigerant pipe 31 in heat exchanger 30, resulting in false alarms. For example, there may be a certain refrigerant concentration at the inlet and outlet of refrigerant pipe 31, which may be detected by sensor 90 as a leak. Placing sensor 90 away from heat exchanger 30 can reduce this interference, allowing sensor 90 to more accurately detect true leaks, such as a rupture in refrigerant pipe 31. Furthermore, when a refrigerant leak occurs, the leaked refrigerant gradually diffuses to other areas within air conditioner 100. Placing sensor 90 away from refrigerant pipe 31 can capture this diffusion process from low to high concentration and determine that the refrigerant has diffused to the bottom, indicating a leak has indeed occurred, thereby improving the sensitivity and accuracy of refrigerant leak detection.

[0088] See also Figure 1 、 Figure 10 and Figure 11 In some embodiments, the side panel 11 is detachably connected to the bottom panel 15 , the side panel 11 is provided with a mounting portion 110 and a handle 120 provided on the mounting portion 110 , and the heat exchanger 30 is provided in the housing 10 .

[0089] In this way, a mounting portion 110 and a handle 120 provided on the mounting portion 110 are provided on the side panel 11, so that the side panel 11 can be removed from the base plate 15 through the handle 120. There is no need to provide a through hole for disassembly and assembly on the side panel 11, thereby reducing the risk of water seepage and heat leakage in the air conditioner 100.

[0090] Specifically, after the side panel 11 is removed, the internal components of the air conditioner 100 can be maintained, for example, the fan of the air conditioner 100 can be maintained.

[0091] See also Figure 10 and Figure 11 In some embodiments, the mounting portion 110 includes two mounting pieces 111 arranged in parallel on the side panel 11, a plug hole 112 is formed between the mounting piece 111 and the side panel 11, and the handle 120 has two opposite free ends 121, which are inserted into the corresponding plug holes 112.

[0092] Thus, the mounting plate 111 facilitates installation of the handle 120. The free end 121 of the handle 120 is inserted into the insertion hole 112, allowing the handle 120 to lift the side panel 11 via the mounting portion 110, thereby facilitating removal of the side panel 11. Specifically, the mounting plate 111 can be secured to the side panel 11 by welding, riveting, or other methods. This allows for greater flexibility in positioning and manufacturing processes for the handle 120, while minimizing the impact on the painting of the side panel 11.

[0093] The middle portion of the mounting plate 111 is arched, thereby forming an insertion hole 112 between the mounting plate 111 and the side panel 11. The ends of the two free ends 121 can be tapered, which can play a guiding role and facilitate the insertion of the handle 120 into the insertion hole 112.

[0094] In some embodiments, the free ends 121 are oriented in the same direction, so that the handle 120 can be inserted into the insertion hole 112 from a single direction, making installation easy.

[0095] See also Figure 11 In some embodiments, a limiting member 130 is provided on at least one free end portion 121 , and the limiting member 130 abuts against the mounting piece 111 to prevent the handle 120 from falling off from the plug hole 112 .

[0096] In this way, the stopper 130 prevents the handle 120 from falling out of the insertion hole 112, thereby stabilizing the position of the handle 120 and reducing vibration and collision problems during transportation of the air conditioner 100. Specifically, the stopper 130 can be a detachable part such as a screw, and the stopper 130 can be tightened onto the handle 120.

[0097] See also Figure 11 In some embodiments, the handle 120 includes a mounting section 122, a connecting section 123 and a holding section 124. The connecting section 123 connects the mounting section 122 and the holding section 124. The holding section 124 and the mounting section 122 are both bent relative to the connecting section 123. The mounting section 122 forms a free end 121, and the mounting section 122 is rotatably provided in the plug-in hole 112.

[0098] In this way, the gripping section 124 and the mounting section 122 are both bent relative to the connecting section 123, creating a gripping space between the gripping section 124 and the side panel 11. This also facilitates gripping the gripping section 124 to remove the side panel 11 from the bottom panel 15. Specifically, when the handle 120 is needed, the handle 120 can be unfolded to create a gripping space between the gripping section 124 and the side panel 11. When the handle 120 is no longer needed, the handle 120 can be folded to fold the gripping section 124 onto the side panel 11.

[0099] See also Figure 11 In some embodiments, an elastic sleeve 140 is provided over the grip section 124. This provides cushioning for the operator's palm, making it easier to grip the handle 120. Furthermore, the elastic sleeve 140 can reduce the noise generated by the handle 120 colliding with the side panel 11. Specifically, the elastic sleeve 140 can be made of a rubber material, which imparts elasticity to the sleeve 140.

[0100] See also Figure 12-14 In some embodiments, the mounting portion 110 includes a bent edge 113 connected to the edge of the side panel 11. The bent edge 113 is provided with a perforation 114, and the handle 120 is an annular belt inserted through the perforation 114. Thus, the use of an annular belt to form the handle 120 provides a simple structure and low cost. Specifically, the number of perforations 114 can be multiple, with the multiple perforations 114 spaced apart along the length of the edge of the side panel 11, and each perforation 114 is inserted through an annular belt. The annular belt may be, for example, a tightening belt.

[0101] See also Figure 15 In some embodiments, a heat-insulating layer 150 is provided on the inner side of the side panel 11. In this way, the heat-insulating layer 150 can reduce the heat or cold leakage of the air conditioner 100.

[0102] In summary, in one embodiment, the air conditioner 100 includes a shell 10 and a heat exchanger 30, the shell 10 includes a base plate 15 and a side plate 11 detachably connected to the base plate 15, the side plate 11 is provided with a mounting portion 110 and a handle 120 arranged on the mounting portion 110; the heat exchanger 30 is arranged in the shell 10.

[0103] In the air conditioner 100 of the embodiment of the present application, a mounting portion 110 and a handle 120 provided on the mounting portion 110 are provided on the side panel 11, so that the side panel 11 can be removed from the base plate 15 through the handle 120. There is no need to provide a through hole on the side panel 11 for disassembly and assembly, thereby reducing the risk of water seepage and heat leakage in the air conditioner 100.
