Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an exhaust structure, a mobile air conditioner and a control method for the mobile air conditioner. Background Art

[0002] Mobile air conditioners are popular in the market because of their easy installation, no need for copper pipes to connect the internal and external units, and easy mobility. However, as an integrated air conditioner, the high-temperature gas generated by the condenser of the mobile air conditioner needs to be discharged to the outside through the heat exhaust duct. The existing heat exhaust duct of the mobile air conditioner is generally within 20 cm in diameter and about 2 meters in length. It is used to connect the condenser duct outlet to discharge the hot air generated by the condenser to the outside.

[0003] In actual use, since the heat exhaust duct is mostly a telescopic hose, and the heat exhaust duct often needs to be bent when the hot air from the condenser is discharged to the outside, this greatly increases the wind resistance of the air outlet of the duct. In order to transmit the hot air generated by the condenser to a farther place, some consumers will choose to lengthen the heat exhaust duct or connect the exhaust duct, which further aggravates the wind resistance problem. The increase in wind resistance leads to a significant reduction in the exhaust volume on the condenser side, which in turn causes the temperature in the condenser air duct to rise sharply. This not only affects the cooling effect of the mobile air conditioner, but also easily causes plastic materials such as the fan blades in the air duct to deform when running at high speed in a high temperature environment. The gap between the fan blade and the volute tongue of the air duct is already narrow. After high-temperature deformation, the fan blade may expand and touch the volute tongue of the air duct, which may cause noise or abnormal noise, and even cause the fan blade to break, causing the mobile air conditioner to lose its cooling capacity.

[0004] Therefore, it is necessary to improve the existing fan to overcome the defects of the prior art. Summary of the invention

[0005] In order to overcome the problems existing in the related art, one of the objects of the present invention is to provide an exhaust structure, which has two exhaust modes and can be used in the exhaust process of a mobile air conditioner; when the exhaust temperature of the condenser is too high, the first through hole and the second through hole overlap to perform bypass exhaust and heat dissipation, thereby improving the exhaust efficiency, avoiding excessive temperature in the condenser air duct, and preventing damage to components such as fan blades.

[0006] An exhaust structure, comprising a joint, wherein the joint is provided with an air inlet and an air outlet that are interconnected, wherein the joint comprises a first cylinder and a second cylinder that are coaxially arranged, wherein the second cylinder is arranged at the periphery of the first cylinder, and the second cylinder is rotatably matched with the first cylinder; a side wall of the first cylinder is provided with a plurality of first through holes, and a side wall of the second cylinder is provided with a plurality of second through holes;

[0007] It also includes a driving mechanism, which is used to drive the first cylinder or the second cylinder to rotate so that the first through hole and the second through hole are staggered or overlapped.

[0008] The exhaust structure can be used in the exhaust process of the air conditioner, and has two exhaust modes. One is that when the first through hole and the second through hole are staggered, the hot air of the condenser flows in from the air inlet and directly flows out from the air outlet; the other is that when the first through hole and the second through hole coincide, after the hot air of the condenser flows in from the air inlet, part of it flows out from the air outlet, and the other part flows out from the first through hole and the second through hole.

[0009] By adjusting the relative position of the first cylinder and the second cylinder through the driving mechanism, different exhaust modes can be easily switched to meet diverse exhaust needs. When the first through hole overlaps with the second through hole, hot air can be discharged through multiple channels at the same time, which significantly improves the heat dissipation efficiency, helps maintain the normal operating temperature of the air conditioner condenser, and prevents damage due to overheating. An effective heat dissipation system can prevent the temperature in the condenser air duct from being too high, thereby protecting key components such as the fan blades from damage and extending the service life of the equipment.

[0010] In a preferred technical solution of the present invention, it also includes an air duct, which is detachably connected to the first cylinder or the second cylinder, and is communicated with the air outlet.

[0011] The detachable connection design between the air duct and the second cylinder makes the installation and maintenance process simpler and faster, reducing the operating difficulty and cost.

[0012] By adding air ducts, the exhaust system of the present application can exhaust hot air to where it is needed while maintaining the original flexible exhaust mode, thereby meeting different usage requirements.

[0013] In a preferred technical solution of the present invention, the second cylinder is rotatably matched with the first cylinder, the driving mechanism drives the first cylinder to rotate around its own axis, and the air duct is detachably connected to the second cylinder.

[0014] In one embodiment, the driving mechanism drives the first cylinder to rotate to change the relative position of the first through hole and the second through hole.

[0015] In a preferred technical solution of the present invention, the second cylinder is rotationally matched with the first cylinder, the driving mechanism drives the second cylinder to rotate around its own axis, and the air duct is detachably connected to the first cylinder.

[0016] In another embodiment, the driving mechanism drives the second cylinder to rotate to change the relative position of the first through hole and the second through hole. This method is different from the method in which the driving mechanism drives the first cylinder to rotate, but both can achieve the purpose of changing the relative position of the first through hole and the second through hole.

[0017] In a preferred technical solution of the present invention, an annular convex strip is provided on the outer wall of the first cylinder, and an annular groove is provided on the inner wall of the second cylinder. When the second cylinder is arranged on the periphery of the first cylinder, the annular convex strip is embedded in the annular groove.

[0018] An external rack is arranged at one end of the first cylinder, and the external rack is arranged in a ring shape on the first cylinder; the driving mechanism includes a driving motor and a gear, the gear is meshed with the external rack, and the output end of the driving motor is fixedly connected to the gear.

[0019] The interlocking design of the annular convex strip and the annular groove enhances the structural stability between the first cylinder and the second cylinder, ensuring the reliability and durability of the exhaust structure during long-term use. The meshing mechanism of the external rack and the gear is used to achieve precise control of the rotation of the first cylinder, making the overlap or stagger of the first through hole and the second through hole more accurate, thereby improving the flexibility and reliability of exhaust mode switching.

[0020] In a preferred technical solution of the present invention, a plurality of limit plates are provided on the outer wall of the second cylinder, and the plurality of limit plates are arranged on the outer wall of the second cylinder along the circumference of the second cylinder.

[0021] The setting of the limiting plate enables the structure to be more conveniently installed at the required position to meet the use requirements.

[0022] In a preferred technical solution of the present invention, it also includes a temperature sensor, which is arranged on the inner wall of the first cylinder and is electrically connected to the driving mechanism.

[0023] The temperature sensor and the drive mechanism are electrically connected to form an intelligent feedback system. When the temperature sensor detects that the hot air temperature exceeds the preset safety threshold, it will immediately send a signal to the drive mechanism. After receiving the signal, the drive mechanism will automatically adjust the position of the first cylinder so that the first through hole coincides with the second through hole, thereby increasing the heat dissipation area, accelerating the discharge of hot air, and reducing the temperature.

[0024] A second object of the present invention is to provide a mobile air conditioner, which includes a main body and the exhaust structure as described above.

[0025] In a preferred technical solution of the present invention, the main body includes a first shell and a second shell, the second shell is arranged on one side of the first shell, and an installation position is formed between the first shell and the second shell, a refrigeration system is arranged in the installation position, the refrigeration system includes a compressor, a condenser, a throttling component and an evaporator connected through a refrigeration pipe, the condenser is arranged below the evaporator, and the condenser and the evaporator are separated from each other by a partition; a condensation air duct is arranged on one side of the condenser, and an air inlet of the exhaust structure is connected to the condensation air duct.

[0026] By optimizing the layout of the refrigeration system and introducing an efficient exhaust structure, the mobile air conditioner can achieve more efficient heat dissipation and ensure the stable operation of the refrigeration system. The two exhaust modes provided by the exhaust structure enable the mobile air conditioner to adapt to different heat dissipation requirements and maintain a good working condition whether in normal cooling or high temperature environment.

[0027] A third object of the present invention is to provide a control method for a mobile air conditioner, wherein the control method is implemented based on the mobile air conditioner as described above;

[0028] The control method comprises the following steps:

[0029] Get the outlet air temperature T of the condenser;

[0030] When the air outlet temperature T is greater than a first temperature preset value and the duration exceeds a first duration preset value, the driving mechanism is started so that the first through hole overlaps with the second through hole;

[0031] Continue to monitor the condenser's outlet air temperature T;

[0032] When the air outlet temperature T is less than the second temperature preset value and the duration exceeds the second time preset value, the driving mechanism is started so that the first through hole is staggered with the second through hole.

[0033] This method realizes the automation and intelligent control of mobile air conditioners by real-time monitoring of the condenser air outlet temperature and intelligently adjusting the exhaust mode. When the condenser temperature is too high, the exhaust area is increased to accelerate heat dissipation; after the temperature drops, the exhaust area is reduced to save energy and reduce noise. This dynamic adjustment strategy not only ensures heat dissipation efficiency, but also takes into account energy consumption and cooling efficiency, which helps to improve user experience.

[0034] The beneficial effects of the present invention are:

[0035] The present invention provides an exhaust structure, which includes a joint and a driving mechanism. The joint is provided with an air inlet and an air outlet that are interconnected. The joint includes a first cylinder and a second cylinder that are coaxially arranged. The second cylinder is arranged on the periphery of the first cylinder, and the second cylinder and the first cylinder can be rotatably matched; the side wall of the first cylinder is provided with a plurality of first through holes, and the side wall of the second cylinder is provided with a plurality of second through holes. The driving mechanism is used to drive the first cylinder or the second cylinder to rotate so that the first through hole and the second through hole are staggered or overlapped. The exhaust structure can be applied in the exhaust process of the air conditioner and has two exhaust modes. One of them is that when the first through hole and the second through hole are staggered, the hot air of the condenser flows in from the air inlet and flows out directly from the air outlet; the other is that when the first through hole and the second through hole overlap, the hot air of the condenser flows in from the air inlet, and a part flows out from the air outlet, and the other part flows out from the first through hole and the second through hole. Different exhaust modes make the exhaust structure flexible to use and can be applied in different occasions. Moreover, when the first through hole and the second through hole overlap to perform bypass exhaust and heat dissipation, the exhaust efficiency can be effectively improved, so that the hot air at the condenser can be quickly discharged, thereby avoiding excessive temperature in the condenser air duct to prevent damage to components such as fan blades, and ensuring the cooling effect of the air conditioner.

[0036] The present application also provides a mobile air conditioner including the above-mentioned exhaust structure and a control method for the mobile air conditioner. The control method can select different exhaust modes according to the exhaust temperature of the condenser of the mobile air conditioner, which can effectively avoid the temperature of the condenser from being too high, and prevent the blades of the exhaust fan of the condenser from being deformed due to excessive temperature, which helps to extend the service life of the equipment and ensure the cooling effect of the mobile air conditioner.

[0048] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0049] In the fields of animal husbandry, breeding, ventilation, etc., the stability and protection level of the fan are crucial to the performance and service life of the equipment. However, in existing fans, the fan blades are usually connected to the motor through a rotating shaft, and their protection design mainly relies on the fan end cover and the related structure matching the end cover. This protection method results in the fan's protection level being usually low, such as IP55, IP56, IP66, etc. Although these levels of protection provide dust and water protection for the fan to a certain extent, in increasingly complex application environments, these protection levels have gradually become difficult to meet actual needs. Especially under extreme working conditions such as humidity, water spraying, on-site disinfection, and cleaning, the limitations of the existing fan protection structure have become increasingly prominent.

[0050] With the rapid development of animal husbandry and breeding industries, the market has put forward higher requirements for the durability, reliability and environmental protection of equipment. Fan motors with high protection levels can operate stably in harsh environments, thereby reducing maintenance costs and downtime and improving production efficiency.

[0051] Based on this, the present application provides an exhaust structure.

[0052] Example 1

[0053] like Figure 1-Figure 5As shown, an exhaust structure provided in this embodiment includes a joint, on which an air inlet and an air outlet that are interconnected are provided, and the joint includes a first cylinder 1 and a second cylinder 2 that are coaxially arranged, the second cylinder 2 is arranged on the periphery of the first cylinder 1, and the second cylinder 2 and the first cylinder 1 are rotatably matched; the side wall of the first cylinder 1 is provided with a plurality of first through holes 12, and the side wall of the second cylinder 2 is provided with a plurality of second through holes 22;

[0054] The device further comprises a driving mechanism 3 for driving the first cylinder 1 or the second cylinder 2 to rotate so that the first through hole 12 and the second through hole 22 are staggered or overlapped.

[0055] Specifically, the air inlet and the air outlet are arranged at two opposite ends of the first cylinder.

[0056] The exhaust structure can be used in the exhaust process of the air conditioner and has two exhaust modes. One of them is that when the first through hole 12 and the second through hole 22 are staggered, the hot air of the condenser 400 flows in from the air inlet and then flows out from the air outlet directly; this mode is suitable for situations where directional exhaust is required.

[0057] Another mode is that when the first through hole 12 and the second through hole 22 overlap, after the hot air of the condenser 400 flows in from the air inlet, a part of it flows out from the air outlet, and the other part flows out from the first through hole 12 and the second through hole 22. This mode increases the discharge channel of the hot air, can significantly improve the heat dissipation efficiency, and avoid equipment damage caused by overheating of the condenser 400.

[0058] By adjusting the relative position of the first barrel 1 and the second barrel 2 through the driving mechanism 3, different exhaust modes can be easily switched to meet diverse exhaust needs. When the first through hole 12 coincides with the second through hole 22, hot air can be discharged through multiple channels at the same time, which significantly improves the heat dissipation efficiency, helps to maintain the normal operating temperature of the air conditioner condenser 400, and prevents damage due to overheating. An effective heat dissipation system can prevent the temperature in the air duct of the condenser 400 from being too high, thereby protecting key components such as the fan blades from damage and extending the service life of the equipment. The coaxial and rotatable ingenious design of the first barrel 1 and the second barrel 2 makes it easier to adjust the exhaust structure. The exhaust mode can be switched by simply driving the barrel to rotate through the driving mechanism 3. It is easy to operate and has strong practicality.

[0059] In the present embodiment, the driving mechanism 3 may include a driving motor 31 and a transmission device. The driving motor 31 is the core component of the driving mechanism 3, and it provides rotational power. This motor may be a stepper motor, a servo motor or a DC motor, and the specific selection depends on the accuracy requirements, cost considerations and the power requirements of the system. The output shaft of the motor is connected to the transmission device through a coupling or a transmission belt to ensure smooth and efficient power transmission. The transmission device may include gears, belts, chains, etc., for transmitting the rotational power of the motor to the first barrel 1 or the second barrel 2.

[0060] The driving mechanism 3 also includes a controller, which can accurately control the rotation speed, direction and angle of the motor according to a preset program or an external input signal, thereby achieving accurate alignment or staggering of the first cylinder 1 and the second cylinder 2.

[0061] Example 2

[0062] This embodiment is improved on the basis of embodiment 1.

[0063] like Figure 1-Figure 5 As shown, in this embodiment, an air duct 4 is also included. The air duct 4 is detachably connected to the first cylinder 1 or the second cylinder 2, and the air duct 4 is communicated with the air outlet.

[0064] The detachable connection design between the air duct 4 and the second cylinder 2 makes the installation and maintenance process simpler and faster, and reduces the operation difficulty and cost.

[0065] By adding the air duct 4, the exhaust system of the present application can exhaust the hot air to where it is needed while maintaining the original flexible exhaust mode, thereby meeting different usage requirements.

[0066] Specifically, the detachable connection modes of the air duct 4 and the first cylinder 1 or the second cylinder 2 are:

[0067] (1) Clamping connection: This connection method uses a special clamp or clamp to clamp the air duct 4 and the cylinder together. This connection method does not require additional fasteners.

[0068] (2) Plug-in connection: In this connection method, a socket is designed on the cylinder, and the end of the air duct 4 is designed into a corresponding plug shape, which is connected by plugging. This connection method is simple and fast, and is suitable for occasions where frequent disassembly is required.

[0069] (3) Magnetic connection: This connection method embeds strong magnets at the connection parts of the air duct 4 and the cylinder. This connection method is very convenient to connect and disassemble, and has good sealing performance.

[0070] Example 3

[0071] This embodiment is improved on the basis of embodiment 1.

[0072] like Figure 1-Figure 5 As shown, in this embodiment, the second cylinder 2 is rotationally matched with the first cylinder 1, the driving mechanism 3 drives the first cylinder 1 to rotate around its own axis, and the air duct 4 is detachably connected to the second cylinder 2.

[0073] In one embodiment, the driving mechanism 3 drives the first cylinder 1 to rotate to change the relative position of the first through hole 12 and the second through hole 22 .

[0074] In a more preferred implementation of this embodiment, an annular convex strip is provided on the outer wall of the first cylinder 1, and an annular groove is provided on the inner wall of the second cylinder 2. When the second cylinder 2 is arranged on the periphery of the first cylinder 1, the annular convex strip is embedded in the annular groove;

[0075] In practical applications, 1-2 annular convex strips may be provided. The annular convex strips are closely attached to the outer wall of the first cylinder 1. The cross-sectional shape thereof may be rectangular, semicircular or other suitable geometric shapes to ensure a good fit and stable fit with the annular groove. In order to provide better structural stability and smooth rotation, the surface of the annular convex strips is usually finely processed to ensure that it is smooth and free of burrs.

[0076] An external rack 11 is provided at one end of the first cylinder 1, and the external rack 11 is annularly arranged on the first cylinder 1; the driving mechanism 3 includes a driving motor 31 and a gear 32, the gear 32 is meshed with the external rack 11, and the output end of the driving motor 31 is fixedly connected to the gear 32.

[0077] The interlocking design of the annular convex strip and the annular groove enhances the structural stability between the first cylinder 1 and the second cylinder 2, ensuring the reliability and durability of the exhaust structure during long-term use. The meshing mechanism of the outer rack 11 and the gear 32 is used to achieve precise control of the rotation of the first cylinder 1, making the overlap or stagger of the first through hole 12 and the second through hole 22 more accurate, thereby improving the flexibility and reliability of exhaust mode switching.

[0078] Example 4

[0079] This embodiment is improved on the basis of embodiment 1.

[0080] like Figure 1-Figure 5 As shown, what is different from Embodiment 3 is that in this embodiment, the driving mechanism 3 drives the second cylinder 2 to rotate instead of the first cylinder 1.

[0081] In this embodiment, the second cylinder 2 is rotatably matched with the first cylinder 1, the driving mechanism 3 drives the second cylinder 2 to rotate around its own axis, and the air duct 4 is detachably connected to the first cylinder 1. The air duct 4 is detachably connected to the first cylinder 1, which is convenient for installation, disassembly and maintenance.

[0082] In this embodiment, although the driving mechanism 3 drives the first cylinder 1 to rotate in a different manner, both can achieve the purpose of changing the relative position of the first through hole 12 and the second through hole 22. This design increases the flexibility of the exhaust structure and enables it to adapt to more diverse application scenarios and needs.

[0083] Example 5

[0084] This embodiment is improved on the basis of embodiment 4.

[0085] like Figure 1-Figure 5 As shown, in this embodiment, the outer wall of the second cylinder 2 is provided with a plurality of limit plates 21 , and the plurality of limit plates 21 are arranged on the outer wall of the second cylinder 2 along the circumference of the second cylinder 2 .

[0086] The design of the limiting plates 21 not only enhances the structural stability of the second cylinder 2, but more importantly, provides a convenient limiting function for the installation process. When the exhaust structure is installed in the housing of a mobile air conditioner or other similar equipment, these limiting plates 21 can ensure the accurate position of the second cylinder 2 during the installation process, thereby significantly improving the installation efficiency.

[0087] In a more preferred embodiment, the limit plate 21 is not only used for installation limiting, but also increases the structural strength of the second cylinder 2, making it more stable during operation and reducing the risk of displacement or damage caused by vibration or external force.

[0088] Example 6

[0089] This embodiment is improved on the basis of embodiment 1.

[0090] like Figure 1-Figure 5 As shown, in this embodiment, a temperature sensor 5 is further included. The temperature sensor 5 is arranged on the inner wall of the first cylinder 1 , and the temperature sensor 5 is electrically connected to the driving mechanism 3 .

[0091] The temperature sensor 5 is introduced as a key component in the embodiment to realize the intelligent temperature control function of the exhaust structure.

[0092] Specifically, the temperature sensor 5 is arranged on the inner wall of the first cylinder 1. Such a position selection can ensure that it accurately monitors the temperature of the hot air passing through the cylinder. The temperature sensor 5 and the driving mechanism 3 are electrically connected to realize data transmission and control instruction transmission.

[0093] This improvement constitutes an intelligent feedback system, and its working principle is as follows: the temperature sensor 5 continuously monitors the temperature of the hot air passing through the first cylinder 1 and transmits the real-time data to the drive mechanism 3. When the detected temperature exceeds the preset safety threshold, the temperature sensor 5 will immediately trigger a signal to the drive mechanism 3. The drive mechanism 3 that receives the signal will automatically respond and adjust the position of the first cylinder 1 to ensure that the first through hole 12 is aligned with the second through hole 22. This alignment increases the heat dissipation area, thereby effectively accelerating the discharge of hot air, thereby reducing the system temperature.

[0094] This intelligent temperature control not only improves the safety performance of the equipment, but also optimizes the heat dissipation efficiency, ensuring the stable operation of the system in high temperature environments. In addition, the design reduces the need for manual intervention, realizes automated management, and further improves the ease of use and reliability of the equipment.

[0095] In this embodiment, the temperature sensor 5 includes, but is not limited to, a thermocouple, a thermistor (such as an NTC or PTC thermistor), an integrated circuit temperature sensor (such as a digital temperature sensor such as LM35, DS18B20), or other applicable temperature sensors. It should be noted that the size and installation method of the temperature sensor 5 should be suitable for installation on the inner wall of the first cylinder 1, and should not affect the normal operation of the exhaust structure.

[0096] Example 7

[0097] This embodiment provides a mobile air conditioner, which includes a main body and the exhaust structure as described above.

[0098] like Figure 6-Figure 8 As shown, in this embodiment, the main body includes a first shell 100 and a second shell 200, the second shell 200 is arranged on one side of the first shell 100, and an installation position is formed between the first shell 100 and the second shell 200, and a refrigeration system is arranged in the installation position, and the refrigeration system includes a compressor, a condenser 400, a throttling component and an evaporator 300 connected through a refrigeration pipeline, the condenser 400 is arranged below the evaporator 300, and the condenser 400 and the evaporator 300 are separated from each other by a partition 500; a condensation air duct 410 is arranged on one side of the condenser 400, and the air inlet of the exhaust structure is connected to the condensation air duct 410. It should be noted that the location of the evaporator 300 is the evaporation chamber of the mobile air conditioner, and the location of the condenser 400 is the condensation chamber of the mobile air conditioner. There is no heat exchange between the evaporation chamber and the condensation chamber to ensure the heat exchange efficiency of the air conditioner. Fans are provided in both the evaporation chamber and the condensation chamber to achieve air supply.

[0099] By optimizing the layout of the refrigeration system and introducing an efficient exhaust structure, the mobile air conditioner can achieve more efficient heat dissipation and ensure the stable operation of the refrigeration system. The two exhaust modes provided by the exhaust structure enable the mobile air conditioner to adapt to different heat dissipation requirements and maintain a good working condition whether in normal cooling or high temperature environment.

[0100] The refrigeration process of the air conditioner's refrigeration system is as follows:

[0101] The compressor sucks in low-temperature, low-pressure refrigerant gas and compresses it through the piston or rotor inside it. The compressed refrigerant gas becomes a high-temperature, high-pressure state, ready to enter the next stage. The high-temperature, high-pressure refrigerant gas is discharged from the compressor and enters the condenser 400. In the condenser 400, the refrigerant gas dissipates heat through the condensation air duct 410 and the exhaust structure, releasing the heat to the external environment. As the heat is released, the refrigerant gas gradually condenses into liquid and becomes a high-temperature, high-pressure liquid refrigerant. The liquid refrigerant then flows through a throttling component, such as a capillary tube or an expansion valve. The function of the throttling component is to reduce the pressure and temperature of the refrigerant, turning it into a low-temperature, low-pressure liquid refrigerant. This process is to prepare the refrigerant to enter the evaporator 300 to absorb the heat in the room. The low-temperature, low-pressure liquid refrigerant enters the evaporator 300. In the evaporator 300, the refrigerant absorbs the heat in the room, thereby achieving a cooling effect. After absorbing the heat, the liquid refrigerant gradually vaporizes and becomes a low-temperature, low-pressure refrigerant gas. The vaporized refrigerant gas is sucked into the compressor again, starting a new refrigeration cycle.

[0102] During the entire refrigeration cycle, at the condensing air duct 410, the exhaust structure ensures that the heat in the condenser 400 can be dissipated to the external environment in a timely manner through efficient exhaust, thereby maintaining the efficient operation of the refrigeration system.

[0103] Example 8

[0104] See also Fig. 9 , this embodiment provides a control method for a mobile air conditioner, and the control method is implemented based on the mobile air conditioner as described above;

[0105] The control method comprises the following steps:

[0106] S100, obtaining the outlet air temperature T of the condenser 400; this step is implemented by a temperature sensor, ensuring real-time monitoring of the working state of the condenser 400.

[0107] S200, when the air outlet temperature T is greater than the first temperature preset value and the duration exceeds the first duration preset value, the drive mechanism 3 is started so that the first through hole 12 overlaps with the second through hole 22; this adjustment can increase the heat dissipation area and accelerate the discharge of hot air, thereby effectively reducing the temperature of the condenser 400. The first temperature preset value can be 80℃-90℃; the first duration preset value is 30 seconds-40 seconds. When T is greater than the first temperature preset value and the duration exceeds the first duration preset value, the temperature in the condenser 400 is too high, so it is necessary to enhance heat dissipation to prevent the fan blades from deforming due to excessive temperature.

[0108] S300, continue to monitor the outlet air temperature T of the condenser 400; after adjusting the exhaust structure, the system continues to monitor the outlet air temperature T of the condenser 400 to keep continuous tracking of the working status of the air conditioner.

[0109] S400. When the air outlet temperature T is less than the second temperature preset value and the duration exceeds the second duration preset value, start the driving mechanism 3 so that the first through hole 12 and the second through hole 22 are staggered. This step is intended to reduce the heat dissipation area, thereby reducing energy consumption and noise levels while meeting the cooling needs. The second temperature preset value can be 60℃-65℃; the first duration preset value is 60 seconds-70 seconds. When the air outlet temperature T is less than the second temperature preset value and the duration exceeds the second duration preset value, it indicates that the temperature in the condenser 400 is not enough to cause deformation of components such as the fan blades. Therefore, the first through hole 12 and the second through hole 22 can be staggered to achieve the optimal cooling effect of the mobile air conditioner while ensuring that the fan blades are not deformed.

[0110] The method realizes the automation and intelligent control of the mobile air conditioner by real-time monitoring of the air outlet temperature of the condenser 400 and intelligently adjusting the exhaust mode. When the temperature of the condenser 400 is too high, the heat dissipation is accelerated by increasing the exhaust area; after the temperature drops, the exhaust area is reduced to save energy and reduce noise. This dynamic adjustment strategy not only ensures the heat dissipation efficiency, but also takes into account energy consumption and cooling efficiency, which helps to improve the user experience.

[0111] The control method of the mobile air conditioner of the present application is described in detail below:

[0112] When the exhaust duct 4 of the mobile air conditioner is severely bent or the exhaust duct 4 is flattened by external force, or the user lengthens the exhaust duct 4, the resistance of the exhaust duct 4 increases, making the heat exchange of the condenser 400 worse. The exhaust temperature of the compressor of the mobile air conditioner will increase significantly, and the outlet temperature of the condenser 400 will also increase accordingly.

[0113] The deformation temperature of the fan blade material is about 90°C. If the temperature sensor 5 detects that the air outlet temperature of the condenser 400 reaches 80°C and exceeds 30 seconds, the controller of the mobile air conditioner will turn on the driving mechanism 3, and the driving mechanism 3 drives the first cylinder 1 or the second cylinder 2 to rotate, so that the first through hole 12 coincides with the second through hole 22. At this time, due to the relatively large static pressure in the heat exhaust duct 4, part of the hot air from the condenser 400 will be discharged through the first through hole 12 and the second through hole 22, which is equivalent to increasing the air volume of the condenser 400, accelerating the heat exchange of the condenser 400, thereby reducing the temperature of the condenser 400, avoiding the problem of poor heat exchange of the condenser 400 due to the obstruction of the heat exhaust duct 4, which leads to the deformation of the fan blade.

[0114] After a period of bypass exhaust, when the temperature sensor 5 detects that the air outlet temperature of the condenser 400 is lower than 65°C and the time exceeds 60 seconds, the air outlet temperature of the condenser 400 is normal and there is no risk of deformation of the fan blades. In order to improve the cooling effect of the mobile air conditioner, the controller of the mobile air conditioner will turn on the driving mechanism 3 to drive the first cylinder 1 or the second cylinder 2 to rotate, so that the first through hole 12 and the second through hole 22 are completely staggered, and all the hot air is discharged to the outdoor side by the exhaust air duct 4. Finally, the optimal cooling effect of the mobile air conditioner is achieved while ensuring that the fan blades are not deformed.

[0115] In actual applications, the mobile air conditioner can be remotely controlled through a mobile phone APP or a smart speaker. The user can remotely set the ideal temperature for the air conditioner to improve the convenience and flexibility of use. In addition, the first temperature preset value, the first time preset value, the second temperature preset value, and the second time preset value can be flexibly adjusted on the mobile phone APP.
