[0002] The air duct structure refers to the pipe and channel system used to transmit hot and cold air in the air conditioning system, which usually includes components such as air inlet, filter, fan, evaporator or condenser. The fan inhales external air from the air inlet, removes impurities through the filter, and then pushes it to the evaporator or condenser by the fan, and finally transports it to the outside through the air duct structure to mix with the air to achieve the air conditioning effect.

[0025] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4 As shown, a dual air duct structure includes an air duct housing 100, a wind wheel 200 and a driving fan 300 for driving the wind wheel 200, the interior of the air duct housing 100 is respectively provided with a first air duct 14 and a second air duct 15 connected to the outside, the first air duct 14 and the second air duct 15 face different air outlet directions, the driving fan 300 is installed between the first air duct 14 and the second air duct 15, the wind wheel 200 is respectively installed on both sides of the driving fan 300 facing the first air duct 14 and the second air duct 15, the driving fan 300 drives the wind wheel 200 to rotate and drives the wind flow to be discharged from the first air duct 14 and / or the second air duct 15 toward the outside.

[0027] Specifically, in some embodiments, the air duct housing 100 is a double air duct structure for forming an air cavity protection shell of the air duct. The air duct housing 100 can be manufactured by left and right side splicing or integrated molding. When the left and right side splicing process is adopted, the wind wheel 200 and the driving fan 300 can be first installed in the middle of the air duct housing 100 and then spliced ​​to form the first air duct 14 and the second air duct 15. When the integrated molding process is adopted, the air duct housing 100 directly forms the first air duct 14 and the second air duct 15, and then the wind wheel 200 and the driving fan 300 are extended from the air inlet and installed in coordination, thereby increasing the durability and stability of the overall air duct structure, reducing the number of components, reducing the assembly time of accessories, and improving the efficiency of production and manufacturing;

[0028] The first air duct 14 and the second air duct 15 are independently arranged in different chambers of the air duct housing 100, and the driving fan 300 is installed in the middle of the air duct housing 100 and is located between the first air duct 14 and the second air duct 15. The driving fan 300 is a double-air duct structure used to drive the wind wheel 200 to rotate so as to drive the air flow from the outside to enter the first air duct 14 and / or the second air duct 15. The driving fan 300 adopts a double-axis motor with two independent output shafts. The driving fan 300 can control different output shafts to rotate forward and reversely separately. The wind wheel 200 is respectively arranged It is installed on the side of the driving fan 300 facing the first air duct 14 and the side of the driving fan 300 facing the second air duct 15. When the driving fan 300 drives the wind wheel 200 to rotate through the output shaft, the wind can be driven to discharge from the first air duct 14 and the second air duct 15 toward the outside, respectively, so that different air ducts can independently take in and out air. When used in conjunction with the cooling module or heating module of the air conditioner, it can ensure a better air outlet effect and reduce the influence of the mutual interference of the traditional double air ducts. It is more effective when it is suitable for movable vertical air conditioners or mobile air conditioners.

[0029] More specifically, the wind wheel 200 is provided with a plurality of wind wheel blades 23 which are arranged at intervals around the central axis of the wind wheel 200. The wind wheel blades 23 are provided with a curved surface shape which is bent in the opposite direction to the rotation direction. The wind wheel blades 23 extend in a direction away from the driving fan 300 and parallel to the central axis of the wind wheel 200. When the wind wheel 200 rotates, the wind wheel blades 23 accelerate the wind flow into the air duct housing 100 through the curved surface shape which is bent in the opposite direction, so that the double air duct structure can quickly absorb and discharge air, thereby improving the efficiency and strength of air intake and exhaust.

[0030] like Figures 2 to 4 As shown, the air duct housing 100 includes a first air duct housing 11, a second air duct housing 12 and an air duct connecting housing 13. The first air duct housing 11 and the air duct connecting housing 13 are spliced ​​together to form the first air duct 14. The second air duct housing 12 and the air duct connecting housing 13 are spliced ​​together to form the second air duct 15. The first air duct 14 is respectively provided with a first air inlet 141 and a first air outlet 142 connected to the outside world. The second air duct 15 is respectively provided with a second air inlet 151 and a second air outlet 152 connected to the outside world. The first air duct 14 and the second air duct 15 are independent of each other and have opposite air outlet directions.

[0031] Specifically, in some embodiments, the air duct housing 100 is manufactured by a left-right side splicing process, and the air duct housing 100 includes three housing components: a first air duct housing 11, a second air duct housing 12, and an air duct connecting housing 13. The first air duct housing 11 and the air duct connecting housing 13 are spliced ​​on a side facing the first air duct 14 to form the first air duct 14, and the second air duct housing 12 and the air duct connecting housing 13 are spliced ​​on a side facing the second air duct 15 to form the second air duct 15. The first air duct housing 11 and the second air duct housing 12 can adopt different outer shapes and different locking positions to avoid errors in the installation position of the two in the air duct connecting housing 13;

[0032] The first air duct 14 is respectively provided with a first air inlet 141 and a first air outlet 142 connected to the outside, the first air inlet 141 is arranged at a position of the first air duct housing 11 close to the driving fan 300, the first air duct housing 11 and the air duct connecting housing 13 are assembled to form the outline of the first air outlet 142, the first wind wheel 200 is installed on a side of the driving fan 300 close to the first air duct housing 11 and is located in the first air duct 14 formed by the first air duct housing 11 and the air duct connecting housing 13. When the driving fan 300 drives the first wind wheel 200 to rotate, the external wind flow enters the first air duct 14 from the first air inlet 141 and is discharged from the first air outlet 142;

[0033] The second air duct 15 is respectively provided with a second air inlet 151 and a second air outlet 152 connected to the outside. The second air inlet 151 is arranged at a position of the second air duct casing 12 close to the driving fan 300. The second air duct casing 12 and the air duct connecting casing 13 are assembled to form the outline of the second air outlet 152. The second wind wheel 200 is installed on a side of the driving fan 300 close to the second air duct casing 12 and is located in the second air duct 15 formed by the second air duct casing 12 and the air duct connecting casing 13. When the driving fan 300 drives the second wind wheel 200 to rotate, the external wind flow enters the second air duct 15 from the second air inlet 151 and is discharged from the second air outlet 152.

[0034] More specifically, the first air inlet 141 and the second air inlet 151 are respectively arranged on both sides of the air duct housing 100 facing opposite directions, and the first air outlet 142 and the second air outlet 152 are respectively arranged on both sides of the air duct housing 100 facing opposite directions, and the first air inlet 141, the first air outlet 142, the second air inlet 151 and the second air outlet 152 are all staggered, so that the air duct housing 100 can take in air from different directions and discharge air from different directions, and each air inlet and air outlet will not interfere with each other to affect the effects of air intake and air outlet.

[0035] like Figure 2 and Figure 4As shown, the wind wheel 200 includes a first wind wheel 21 and a second wind wheel 22, and the two sides of the driving fan 300 are respectively provided with a first output shaft 31 and a second output shaft 32 that can rotate independently, the first wind wheel 21 is installed on the first output shaft 31 and is located near the first air inlet 141, and the second wind wheel 22 is installed on the second output shaft 32 and is located near the second air inlet 151.

[0036] Specifically, in some embodiments, the driving fan 300 is provided with a first output shaft 31 and a second output shaft 32 that can rotate independently on both sides facing in opposite directions, the first wind wheel 21 is limitedly installed on the first output shaft 31 and can rotate synchronously with the first output shaft 31, and the second wind wheel 22 is limitedly installed on the second output shaft 32 and can rotate synchronously with the second output shaft 32. When the user needs to exhaust air from the first air duct 14, the driving fan 300 is controlled to rotate the first output shaft 31 alone to drive the first wind wheel 21 to rotate. When the first wind wheel 21 rotates, the airflow is sucked into the first air duct 14 from the first air inlet 141. And the air flow is output from the first air outlet 142. When the user needs to exhaust air from the second air duct 15, the control driving fan 300 rotates the second output shaft 32 alone to drive the second wind wheel 22 to rotate. When the second wind wheel 22 rotates, the air flow is sucked into the second air duct 15 from the second air inlet 151 and output from the second air outlet 152, thereby achieving the effect that different air ducts can independently intake and exhaust air. When used in conjunction with the cooling module or heating module of the air conditioner, it can ensure a better air outlet effect and reduce the influence of mutual interference of the traditional double air ducts. It is more effective when it is suitable for movable vertical air conditioners or mobile air conditioners.

[0037] More specifically, the first wind wheel 21, the first air inlet 141 and the first output shaft 31 are all on the same axis, the second wind wheel 22, the second air inlet 151 and the second output shaft 32 are all on the same axis, the first wind wheel 21 and the first air inlet 141 are as close to each other as possible without touching each other, and the second wind wheel 22 and the second air inlet 151 are as close to each other as possible without touching each other, thereby reducing the size of the gap and ensuring the air duct sealing of the first air duct 14 and the second air duct 15. With such a design, the external wind flow can enter the first air duct 14 and the second air duct 15 more smoothly, and the air volume loss in the first air duct 14 and the second air duct 15 is reduced, thereby improving the air volume output efficiency after the wind flow is inhaled.

[0038] like Figure 2 and Figure 3 As shown, the first air outlet 142 and the second air outlet 152 adopt a trumpet-shaped structure 16 , the trumpet-shaped structure 16 of the first air outlet 142 opens from the first air duct 14 toward the outside, and the trumpet-shaped structure 16 of the second air outlet 152 opens from the second air duct 15 toward the outside.

[0039] Specifically, in some embodiments, the first air outlet 142 and the second air outlet 152 both adopt a trumpet-shaped structure 16 that gradually opens from the inside to the outside, the smaller side of the trumpet-shaped structure 16 is connected to the first air duct 14 or the second air duct 15, and the larger side of the trumpet-shaped structure 16 faces the outside. When the wind flows from the first air duct 14 through the gradually opening trumpet-shaped structure 16 at the first air outlet 142, it will gradually disperse to form an air flow with lower density. When the wind flows from the second air duct 15 through the gradually opening trumpet-shaped structure 16 at the second air outlet 152, it will gradually disperse to form an air flow with lower density. The air flow with lower density will feel more natural when it contacts the human body. The trumpet-shaped structure 16 can diffuse the wind flow to a wider range, further improve the air outlet effect, expand the air outlet range, and make the air outlet feel more natural.

[0040] More specifically, a portion of the trumpet-shaped structure 16 of the first air outlet 142 is arranged on the first air duct shell 11, and another portion of the structure is arranged on the air duct connecting shell 13, and the first air duct shell 11 and the air duct connecting shell 13 are assembled together to form a complete trumpet-shaped structure 16 of the first air outlet 142; a portion of the trumpet-shaped structure 16 of the second air outlet 152 is arranged on the second air duct shell 12, and another portion of the structure is arranged on the air duct connecting shell 13, and the second air duct shell 12 and the air duct connecting shell 13 are assembled together to form a complete trumpet-shaped structure 16 of the second air outlet 152. By adopting such a design, it is possible to integrate the structure to reduce components, simplify the production process, shorten the assembly time, and improve the efficiency of production and manufacturing.

[0041] like Figure 3 and Figure 4 As shown, the diameter of the first air inlet 141 is smaller than the outer diameter of the first wind wheel 21, the diameter of the second air inlet 151 is smaller than the outer diameter of the second wind wheel 22, the first air inlet 141 is coaxially arranged with the first output shaft 31, and the second air inlet 151 is coaxially arranged with the second output shaft 32.

[0042] Specifically, in some embodiments, in order to further improve the sealing performance of the first air duct 14, the diameter of the first air inlet 141 is designed to be smaller than the outer diameter of the first wind wheel 21. After installation, the side of the first wind wheel 21 close to the first air duct housing 11 is close to but does not contact the first air duct housing 11, so that the wind flow of the first air duct 14 is minimized from being lost and dispersed from the first air inlet 141. At the same time, in order to further improve the sealing performance of the second air duct 15, the diameter of the second air inlet 151 is designed to be smaller than the outer diameter of the second wind wheel 22. After installation, the second wind wheel 22 is close to the side of the second air duct shell 12 but does not touch the second air duct shell 12, so that the wind flow of the second air duct 15 is minimized from being lost and dispersed from the second air inlet 151, ensuring that the first air duct 14 or the second air duct 15 can improve the conversion rate of air intake and discharge when absorbing air volume, ensuring the normal output wind force of the dual air duct structure, and the wind wheel 200 will not easily fall out of the first air inlet 141 or the second air inlet 151, avoiding the safety hazard of the wind wheel falling out of the air duct.

[0043] like Figure 5 and Figure 6 As shown, an air conditioner includes an air conditioner main body and the dual air duct structure installed in the air conditioner main body, the air conditioner main body includes a whole machine casing 400, a temperature control module 500 and a control module, the whole machine casing 400 is respectively provided with a first air inlet net 41 corresponding to the position of the first air inlet 141, a second air inlet net 42 corresponding to the position of the second air inlet 151, a first air outlet net 43 corresponding to the position of the first air outlet 142 and a second air outlet net 44 corresponding to the position of the second air outlet 152, the temperature control module 500 is used to adjust the air temperature and is respectively arranged at the first air inlet 141 and the second air inlet 151, the control module is respectively electrically connected to the driving fan 300 and the temperature control module 500 to control the driving fan 300 to drive the wind wheel 200 to output airflows of different temperatures from the first air duct 14 and the second air duct 15 toward the outside.

[0044] Specifically, in some embodiments, the dual-duct structure can be used in an air conditioner as a fan device for airflow intake and output. The whole machine casing 400 is a shell installed on the outside of the air conditioner body for decoration and protection. The whole machine casing 400 includes side casings installed on different sides of the air conditioner body, and the tops of the side casings on the left and right sides of the air conditioner body are provided with grips that are recessed toward the inside of the air conditioner body. The grips are provided for users to hold and lift the air conditioner body and move it to an ideal placement position to adjust the air outlet direction and air outlet effect of the air conditioner. The first air inlet net 41, the second air inlet net 42, the first air outlet net 43 and the second air outlet net 44 are respectively arranged on the side casings corresponding to the air inlet or air outlet positions. More specifically, the first air inlet net 41 and the second air inlet net 42 are respectively arranged on the side casings corresponding to the air inlet or air outlet positions. The second air inlet net 42 adopts a honeycomb structure mesh with a hexagonal hole structure and is respectively arranged on the side shells on the left and right sides of the air conditioner body. The first air outlet net 43 adopts a horizontally spaced vertical straight strip structure mesh and is arranged on the side shell on the front side of the air conditioner body. The second air outlet net 44 adopts a hole-shaped structure mesh with circular holes staggered and is arranged on the side shell on the rear side of the air conditioner body. Such a design allows users to more intuitively distinguish the shapes of the air inlet and the air outlet, thereby distinguishing the positions of the air inlet and the air outlet. It also allows users to more intuitively distinguish the shapes of the cold air outlet and the hot air outlet, thereby distinguishing the positions of the cold air outlet and the hot air outlet. The function partition can be identified by the shape without turning on the machine, and the position of the air conditioner can be adjusted more conveniently.

[0045] The temperature control module 500 is a temperature control device installed on the air conditioner body and used to adjust the temperature of the output air flow in cooperation with the dual air duct structure. When the driving fan 300 drives the first wind wheel 21 so that the external air flow passes through the first air inlet 141, the temperature control module 500 can heat or cool the passing air flow, so that the first air duct 14 can output warm air or cold air. Similarly, when the driving fan 300 drives the second wind wheel 22 so that the external air flow passes through the second air inlet 151, the temperature control module 500 can heat or cool the passing air flow, so that the second air duct 15 can also output warm air or cold air, so that the first air duct 14 and / or the second air duct 15 can output warm air or cold air separately.

[0046] The control module is a central processing system installed on the air conditioner body for controlling the operation of functional modules including the driving fan 300 and the temperature control module 500. A plurality of control buttons connected to the control module are arranged on the top of the air conditioner body. When using the air conditioner, the user can operate the control module through the control buttons to control the output shaft of the driving fan 300 on one side or both sides to rotate forward and reverse, so as to realize the outlet of the air duct on one side or the outlet of the air duct on both sides at the same time. The user can also control the temperature control module 500 to adjust the temperature of the air passing through the air inlet by operating the control module, so that the air flow has the characteristics of lower or higher temperature, which can be used by the user to cool down and dissipate heat or heat up and keep warm, thereby realizing the temperature adjustment function of the air conditioner;

[0047] More specifically, the interior of the air conditioner body includes an upper fixing plate 46 and a lower fixing plate 47 for installing the dual duct structure, and the duct housing 100 is located between the upper fixing plate 46 and the lower fixing plate 47 to improve the structural stability of the dual duct structure and reduce the wind noise.

[0048] Specifically, in some embodiments, in order to further reduce the external volume of the air conditioner body, the dual air duct structure is used to provide temperature control mounting structures 17 for accommodating the temperature control module 500 on both sides of the air inlet, and the temperature control mounting structures 17 are respectively arranged at the positions of the first air inlet 141 and the second air inlet 151, and the temperature control mounting structure 17 is connected to the first air inlet 141 or the second air inlet 151. The temperature control module 500 is installed and fixed on the temperature control mounting structure 17 and can be used in conjunction with the dual air duct structure. The user can adjust the air volume of the air intake by adjusting the size of the temperature control mounting structure 17 to reduce the spacing distance between the temperature control module 500 and the air duct housing 100.

[0049] like Figure 6 As shown, the temperature control module 500 includes a cooling module 51 and a heating module 52 . The cooling module 51 is installed at one of the first air inlet 141 and the second air inlet 151 , and the heating module 52 is installed at the other of the first air inlet 141 and the second air inlet 151 .

[0050] Specifically, in some embodiments, the refrigeration module 51 is a refrigeration component used by the temperature control module 500 to produce cold air to achieve cooling and heat dissipation. The temperature control installation structure 17 includes a refrigeration installation structure 171 located at the first air inlet 141. The refrigeration module 51 is installed on the refrigeration installation structure 171. The refrigeration module 51 includes a compressor, a condenser and an evaporator. During refrigeration, the compressor inhales low-pressure, low-temperature refrigerant gas, and then increases the pressure and temperature of the gas by compression, and then transports the high-temperature and high-pressure gas to the condenser. After the gas contacts the condenser, it releases heat and cools to become a high-pressure liquid refrigerant. The high-pressure liquid refrigerant is decompressed by a throttle valve and becomes a low-pressure liquid refrigerant. The low-pressure liquid refrigerant enters the evaporator to absorb indoor heat and evaporates to become a low-temperature vapor. The low-temperature vapor enters the compressor again, and the above steps are cyclically performed. In this process, the phase change of the refrigerant and the heat absorption and release effect of heat achieve the refrigeration effect of the air conditioner.

[0051] The heating module 52 is a heating component used by the temperature control module 500 to produce warm air to achieve heating and warmth. The temperature control mounting structure 17 includes a heating mounting structure 172 located at the second air inlet 151. The heating module 52 is installed on the heating mounting structure 172. The heating module 52 includes a PTC heater. PTC heating refers to a heating method using a positive temperature coefficient (Positive Temperature Coefficient) material as a heating element. The working principle of PTC heating is based on the characteristics of the PTC material. When the PTC material is energized by current, its resistance will increase with the increase in temperature. This change is because when the temperature of the material rises, its internal lattice structure changes, resulting in the obstruction of electron movement, thereby increasing the resistance, so that when the PTC material reaches a certain temperature, the resistance increases sharply, thereby limiting the passage of current, reducing the heating power, and achieving the effect of automatic temperature control. Therefore, when the PTC heater reaches a certain temperature, it automatically limits the heating power, can operate more safely, and prevent the device from overheating.

[0052] Specifically, in some embodiments, when the cooling module 51 is installed at the first air inlet 141, the heating module 52 is installed at the second air inlet 151. When in use, the control module can control the driving fan 300 to rotate the first output shaft 31 alone to drive the first wind wheel 21 to rotate. When the first wind wheel 21 rotates, airflow is sucked in from the first air inlet 141. When the airflow passes through the cooling module 51, the temperature of the airflow is reduced by the above-mentioned refrigeration principle to form low-temperature cold air. The cold air is output from the first air outlet 142 in the first air duct 14 to the outside, thereby realizing the refrigeration function of the air conditioner.

[0053] The control module can also control the driving fan 300 to rotate the second output shaft 32 alone to drive the second wind wheel 22 to rotate. When the second wind wheel 22 rotates, air flow is sucked in from the second air inlet 151. When the air flow passes through the heating module 52, the temperature of the air flow is increased through the above-mentioned heating principle to form high-temperature warm air. The warm air is output to the outside from the second air outlet 152 in the second air duct 15, thereby realizing the heating function of the air conditioner.

[0054] Specifically, in some embodiments, when the cooling module 51 is installed at the second air inlet 151, the heating module 52 is installed at the first air inlet 141. When in use, the control module can control the driving fan 300 to rotate the second output shaft 32 alone to drive the second wind wheel 22 to rotate. When the second wind wheel 22 rotates, the wind flow is sucked in from the second air inlet 151. When the wind flow passes through the cooling module 51, the temperature of the wind flow is reduced by the above-mentioned refrigeration principle to form low-temperature cold air. The cold air is output from the second air outlet 152 to the outside in the second air duct 15, thereby realizing the refrigeration function of the air conditioner.

[0055] The control module can also control the driving fan 300 to rotate the first output shaft 31 alone to drive the first wind wheel 21 to rotate. When the first wind wheel 21 rotates, air flow is sucked in from the first air inlet 141. When the air flow passes through the heating module 52, the temperature of the air flow is increased through the above-mentioned heating principle to form high-temperature warm air. The warm air is output from the first air outlet 142 to the outside in the first air duct 14, thereby realizing the heating function of the air conditioner.

[0056] like Figure 6 As shown, the air conditioner main body includes an atomizing device 6 and a clean water tank. The atomizing device 6 is connected to the clean water tank and the first air duct 14 respectively through a connecting pipe. The control module is electrically connected to the atomizing device 6. The clean water tank supplies water to the atomizing device 6 to generate water mist, and then transports the water mist to the first air duct 14 to be discharged to the outside in coordination with the wind flow.

[0057] Specifically, in some embodiments, the atomizing device 6 is an atomizer of the air-conditioning body for generating water mist gas. The atomizing device 6 is installed on the upper fixing plate 46. The atomizing device 6 can generate steam or vibration by heating or ultrasonic means, and then convert the liquid into fine droplets or mist particles. The mist particles can flow to the outside with the air to achieve the effect of cooling and humidification. The water tank 8 is a water storage tank installed at the bottom of the air-conditioning body for supplying water to the atomizing device 6. The water tank 8 includes a clean water tank, which stores relatively clean domestic water. When in use, the control module controls the driving fan 300 to drive the first wind wheel 21 to The first air duct 14 rotates, and at the same time, the atomizing device 6 is started to extract the water in the clean water tank to generate water mist gas. The water mist gas is transported to the first air duct 14 through the connecting pipe and output to the outside from the first air inlet 141 together with the wind flow in the first air duct 14. The user can realize multiple different uses such as separate cooling, separate atomization humidification or simultaneous cooling and humidification through the control module. Compared with the cold air output by traditional refrigeration, the cold air humidified by the atomizing device 6 is cooler and cooler, can reduce the temperature of the surrounding environment more quickly, and improve the cooling efficiency. Moreover, the cold air after humidification is not as dry as the cold air of traditional refrigeration, which improves the user experience.

[0058] like Figure 6 As shown, the air conditioner main body includes a shower pipe 7, a temperature sensor and a waste water tank. The shower pipe 7 and the temperature sensor are installed above the heating module 52, and the waste water tank is connected to the bottom of the heating module 52. When the temperature sensor detects that the temperature of the heating module 52 is too high, the waste water tank supplies water to the shower pipe 7 through a connecting pipe, and the drainage of the shower pipe 7 flows through the heating module 52 and returns to the waste water tank.

[0059] Specifically, in some embodiments, in order to further adjust the temperature of the heating module 52 in real time and prevent the heating module 52 from overheating, the shower pipe 7 and the temperature sensor are installed on the upper fixed plate 46 above the heating module 52 in this embodiment. The water tank 8 includes a waste water tank, which is separated and independently arranged from the clean water tank. The waste water tank stores cooling water for recycling during cooling. The lower fixed plate 47 is provided with a reflux water inlet for cooling water to flow into the waste water tank. The lower part of the heating module 52 is connected to the waste water tank through the reflux water inlet so that the cooling water flowing through the heating module 52 can flow back to the waste water tank for reuse. The temperature sensor faces the heating module 52. The thermal module 52 is configured to detect the outside temperature of the heating module 52 in real time. When it is found that the temperature of the heating module 52 is overheated, the temperature sensor sends a corresponding signal to the control module to control the waste water tank to supply water to the shower pipe 7. The outside temperature of the heating module 52 is reduced by pumping water from the waste water tank to the shower pipe 7 and adopting rain cooling. Due to repeated contact with the cooling part, the cooling water cannot be used for other related purposes of contacting the human body or being inhaled by the human body. The cooling water needs to be cleaned and replaced regularly to ensure that harmful substances or dust are cleaned in time, and it is also convenient for users to replenish the running water evaporated by cooling.

[0060] like Figure 5 and Figure 6 As shown, a pulley block for facilitating movement is provided at the bottom of the air conditioner body, and the pulley block includes a universal pulley 9 arranged at a bottom corner of the air conditioner body.

[0061] Specifically, in some embodiments, a plurality of universal pulleys 9 are evenly spaced at the bottom corners of the air-conditioning body. The universal pulleys 9 can rotate freely and roll and slide on the ground. The universal pulleys 9 have the characteristics of flexible rotation and steering. When used on the air-conditioning body, the user can move the air-conditioning body to an ideal display position at will without the need to manually lift the air-conditioning body. More specifically, the universal pulley 9 is also provided with a brake portion that can be parked in place. The universal pulley 9 can be stopped at the display position by the brake portion after moving, so that the air-conditioning body will not shake or shift at will during operation, thereby avoiding affecting the air outlet direction and air outlet effect.

[0062] like Figures 1 to 4 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0063] When the dual air duct structure is used, the user turns on the power to drive the fan 300 and then rotates the first output shaft 31 to drive the first wind wheel 21 to rotate. When the first wind wheel 21 rotates, airflow is sucked into the first air duct 14 from the first air inlet 141 and airflow is output from the first air outlet 142, so that the first air duct 14 can be discharged normally.

[0064] After the user connects the power supply to the driving fan 300, the second output shaft 32 is rotated alone to drive the second wind wheel 22 to rotate. When the second wind wheel 22 rotates, the air flow is sucked into the second air duct 15 from the second air inlet 151 and the air flow is output from the second air outlet 152, thereby achieving normal air outlet of the second air duct 15. In this way, the effect of different air ducts being able to independently intake and exhaust air is achieved.

[0065] like Figures 1 to 6 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0066] Different from Example 1, the dual duct structure of this embodiment is applied to the air conditioner, and the user can operate the control module through the control button to control the operation of the air conditioner and the dual duct structure. The cooling module 51 is installed at the first air inlet 141, and the heating module 52 is installed at the second air inlet 151.

[0067] The air duct housing 100 is installed between the upper fixing plate 46 and the lower fixing plate 47. The first air inlet 141 is arranged in the direction of the first air inlet net 41, the second air inlet 151 is arranged in the direction of the second air inlet net 42, the first air outlet 142 is arranged in the direction of the first air outlet net 43, and the second air outlet 152 is arranged in the direction of the second air inlet net 44. The cooling module 51 is installed in the cooling installation structure 171 near the first air inlet 141, and the heating module 52 is installed in the heating installation structure 172 near the second air inlet 141. The user can also move the position of the air conditioner body through the universal pulley 9. The four universal pulleys 9 are respectively and dispersedly installed at the bottom of the air conditioner body, and the user pushes the air conditioner body to the ideal display position;

[0068] When the fan 300 drives the first wind wheel 21 to rotate, the external wind flow is sucked in from the first air inlet 141, and the wind flow passes through the refrigeration module 51 and is cooled by the above-mentioned refrigeration principle to form cold air. After the cold air enters the first air duct 14, it is agitated by the first wind wheel 21. The first wind wheel 21 rotates to guide the cold air to be blown out of the first air duct 14 and out of the first air outlet 142 to reduce the temperature of the outside world.

[0069] When the fan 300 drives the second wind wheel 22 to rotate, the external wind flow is sucked in from the second air inlet 151, and the wind flow passes through the heating module 52 and is cooled by the heating principle to form warm air. The warm air enters the second air duct 15 and is blown by the second wind wheel 22. The second wind wheel 22 rotates to guide the cold air to be blown out of the first air outlet 142 from the first air duct 14, so as to increase the temperature of the outside.

[0070] The temperature sensor is arranged toward the heating module 52 to detect the outer temperature of the heating module 52 in real time. When it is found that the temperature of the heating module 52 is overheated, the temperature sensor sends a corresponding signal to the control module to control the wastewater tank to supply water to the shower pipe 7. The outer temperature of the heating module 52 is reduced by pumping water from the wastewater tank to the shower pipe 7 and adopting shower cooling method. The lower fixed plate 47 is provided with a return water inlet for cooling water to flow into the wastewater tank. The bottom of the heating module 52 is connected to the wastewater tank through the return water inlet so that the cooling water flowing through the heating module 52 can flow back to the wastewater tank for reuse.

[0071] like Figures 1 to 6 As shown, the specific implementation of Example 3 of the utility model is as follows:

[0072] Different from Example 2, the air-conditioning body of this embodiment also includes an atomizing device 6 for improving the cooling effect. When in use, the control module controls the driving fan 300 to drive the first wind wheel 21 to rotate in the first air duct 14, and at the same time starts the atomizing device 6 to extract the water from the clean water tank to generate water mist gas. The water mist gas is transported to the first air duct 14 through the connecting pipe and is output to the outside through the first air inlet 141 together with the wind flow in the first air duct 14. The user can use the control module to achieve multiple different uses such as separate cooling, separate atomizing humidification or simultaneous cooling and humidification.

[0073] like Figure 5 As shown, the specific implementation of Example 4 of the utility model is as follows:

[0074] Different from Embodiment 2 and Embodiment 3, the cooling module 51 of this embodiment is installed at the second air inlet 151 , and the heating module 52 is installed at the first air inlet 141 .

[0075] When in use, the control module can control the driving fan 300 to rotate the second output shaft 32 alone to drive the second wind wheel 22 to rotate. When the second wind wheel 22 rotates, airflow is sucked in from the second air inlet 151. When the airflow passes through the refrigeration module 51, the temperature of the airflow is reduced through the above-mentioned refrigeration principle to form low-temperature cold air. The cold air is output to the outside from the second air outlet 152 in the second air duct 15, thereby realizing the refrigeration function of the air conditioner.

[0076] The control module can also control the driving fan 300 to rotate the first output shaft 31 alone to drive the first wind wheel 21 to rotate. When the first wind wheel 21 rotates, air flow is sucked in from the first air inlet 141. When the air flow passes through the heating module 52, the temperature of the air flow is increased through the above-mentioned heating principle to form high-temperature warm air. The warm air is output from the first air outlet 142 to the outside in the first air duct 14, thereby realizing the heating function of the air conditioner.

[0077] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
