With the increasing number of application scenarios, the types of air conditioners have also increased, such as bathroom air conditioners and kitchen air conditioners. In the bathroom setting, a large amount of fog can easily obstruct the user's view during showering. Related technologies often use defogging to directly expel the fogged air outdoors, causing a significant loss of indoor heat and resulting in a drop in indoor temperature. This lower temperature leads to a poor user experience and may even pose a risk of catching a cold. Summary of the Invention

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0043] An air conditioning device 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0044] like Figures 1-3As shown, the air conditioning device 100 according to an embodiment of the present invention includes: a housing 1, a fan module 2, a defogging module 3, a dehumidifying module 4, and a heating module 5. The housing 1 has an airflow channel 11 and an indoor air inlet 12 and an indoor air outlet 13 communicating with the airflow channel 11. The fan module 2 is disposed within the airflow channel 11 to drive airflow. That is, the fan module 2 can drive indoor air into the airflow channel 11 through the indoor air inlet 12, and can discharge the air conditioned by the air conditioning device 100 into the indoor space through the indoor air outlet 13, thereby achieving forced air circulation between the indoor space and the air conditioning device 100 to gradually condition the indoor air.

[0045] The defogging module 3, dehumidifying module 4, and heating module 5 are all located within the airflow channel 11. The defogging module 3 removes water mist from the air drawn in from the indoor air inlet 12. The dehumidifying module 4 is located downstream of the defogging module 3, and the heating module 5 is located downstream of the dehumidifying module 4. Here, "downstream" refers to the side downstream of the airflow channel 11. That is, as air enters the airflow channel 11 from the indoor air inlet 12 and exits through the indoor air outlet 13, the airflow sequentially passes through the defogging module 3, the dehumidifying module 4, and the heating module 5, and finally exits into the indoor space through the indoor air outlet 13.

[0046] In other words, when there is fog in the indoor space, such as when the air conditioning unit 100 is installed in a bathroom, and fog easily obstructs the user's view during bathing, the fan module 2 drives airflow, causing the fog in the bathroom to enter the airflow channel 11 through the indoor air inlet 12 and first come into contact with the defogging module 3. The defogging module 3 removes water mist from the air, that is, removes liquid water carried in the air, thereby reducing the water content in the air. The air continues to flow and comes into contact with the dehumidification module 4. The dehumidification module 4 can liquefy and intercept the gaseous water in the air through condensation and other methods, further reducing the water content in the air. Thus, the air can be dried through the defogging module 3 and the dehumidification module 4. The dried airflow can be heated by the heating module 5 and then discharged into the indoor space through the indoor air outlet 13. That is, the air conditioning unit 100 can draw in air carrying a large amount of fog from the indoor space, and after drying and heating the airflow, discharge dry and warm air into the indoor space.

[0047] Therefore, it can remove indoor fog while maintaining indoor temperature, thus avoiding user discomfort and the risk of catching a cold caused by a drop in indoor temperature. It also effectively prevents fog from obstructing the user's vision, making it easier to retrieve items while showering, and reduces the risk of slipping and falling. Furthermore, the air conditioning unit 100's drying process effectively reduces indoor humidity, keeping the indoor environment dry and preventing mold growth caused by dampness.

[0048] According to an embodiment of the present invention, the air conditioning device 100, by all disposed within the airflow channel 11, includes a defogging module 3, a dehumidifying module 4, and a heating module 5. The defogging module 3 removes water mist from the air drawn in from the indoor air inlet 12, thus maintaining the indoor temperature while removing fog. This avoids user discomfort and the risk of catching a cold due to a drop in indoor temperature, and also prevents fog from obstructing the user's view, making it easier for the user to retrieve items while showering. Furthermore, it prevents the user from slipping and falling. In addition, it keeps the indoor space dry, thus preventing mold growth caused by dampness.

[0049] According to some embodiments of the present invention, such as Figures 2-4 As shown, the airflow channel 11 includes a connected air conditioning duct 111 and an air outlet channel 112. The air outlet channel 112 includes a first air outlet channel 112a and a second air outlet channel 112b spaced apart. A first outdoor air outlet 14a is also formed on the housing 1. The first air outlet channel 112a connects the air conditioning duct 111 and the first outdoor air outlet 14a. The second air outlet channel 112b connects the air conditioning duct 111 and the indoor air outlet 13.

[0050] In other words, the first outdoor air outlet 14a is connected to the outdoor space, the two ends of the first air outlet duct 112a are connected to the air conditioning duct 111 and the first outdoor air outlet 14a respectively, and the two ends of the second air outlet duct 112b are connected to the air conditioning duct 111 and the indoor air outlet 13 respectively. Driven by the fan module 2, the air in the indoor space can enter the air conditioning duct 111 through the indoor air inlet 12, and some of the air in the air conditioning duct 111 can be directly discharged to the outside space through the first air outlet duct 112a and the first outdoor air outlet 14a. That is, the air conditioning device 100 has an exhaust mode. Therefore, when the air quality in the indoor space is substandard, such as when there are many harmful substances in the air, the harmful gases in the indoor space can be quickly discharged by opening the first outdoor air outlet 14a, which helps to create a healthy and safe breathing environment for users. In addition, the air can effectively improve the stuffy environment in the indoor space during the airflow process.

[0051] Secondly, when there is a lot of fog in the indoor space, the first outdoor air outlet 14a can be closed and the indoor air outlet 13 can be opened, so that the air in the indoor space can be dried and heated by the defogging module 3, the dehumidifying module 4 and the heating module 5 and then discharged back into the indoor space through the second air outlet 112b and the indoor air outlet 13, so as to maintain the indoor space temperature while removing the fog in the indoor space.

[0052] According to some optional embodiments of the present invention, the heating module 5 includes a condenser 51 disposed within the air conditioning duct 111. The condenser 51 can release heat to the outside, that is, it can release heat into the air conditioning duct 111, thereby heating the airflow within the air conditioning duct 111. The condenser 51 includes a first condensing section 51a disposed opposite to the first air outlet channel 112a and a second condensing section 51b disposed opposite to the second air outlet channel 112b.

[0053] In other words, the airflow heated by the second condenser 51b can be discharged back into the indoor space through the second air outlet 112b and the indoor air outlet 13, thus discharging dry and warm airflow into the indoor space. However, heat is generated when the fan module 2 and other components are operating, causing the temperature inside the airflow channel 11 to rise, which in turn affects the heating accuracy of the airflow by the heating module 5. Therefore, the heat generated during the operation of the air conditioning equipment 100 can be discharged through the first air outlet 112a and the first outdoor air outlet 14a, thereby reducing the interference of the heat generated by the operation of the air conditioning equipment 100 on the heating accuracy of the airflow. In addition, the airflow flowing towards the first air outlet 112a can effectively carry away the heat on the first condenser 51a by contacting it, and can be discharged to the outside space through the first outdoor air outlet 14a. Furthermore, heat can be transferred between the first condenser 51a and the second condenser 51b, thereby better controlling the heating amplitude of the airflow by the condenser 51.

[0054] Therefore, the temperature inside the air conditioning duct 111 can be better controlled, thereby controlling the heating effect of the condenser 51 on the airflow discharged into the indoor space. This allows for precise control of the airflow temperature discharged into the indoor space. For example, when a user is taking a bath in the summer, by controlling the airflow temperature discharged into the indoor space, the user can better avoid the dryness caused by excessively hot gas being discharged into the indoor space, thus improving the user's experience.

[0055] According to some optional embodiments of the present invention, the air conditioning device 100 further includes a partition 16, which is adapted to divide the air outlet duct 112 into a first air outlet duct 112a and a second air outlet duct 112b, with the first air outlet duct 112a located above the second air outlet duct 112b. Hot air has the characteristic of rising, that is, the hotter air gathers towards the upper part of the air conditioning duct 111, facilitating the airflow to carry away heat as it is discharged to the outside space through the first air outlet duct 112a and the first outdoor air outlet 14a, thereby controlling the temperature within the air conditioning duct 111.

[0056] Furthermore, one end of the partition 16 is connected to the inner wall of the housing 1, and the other end of the partition 16 abuts against the wall surface downstream of the condenser 51. In other words, the partition 16 can provide good support between the condenser 51 and the housing 1, thereby effectively preventing the condenser 51 from shaking after installation and facilitating the secure installation of the condenser 51.

[0057] Furthermore, the heating module 5 also includes an electric auxiliary heating element 52, which is located within the second air outlet channel 112b. That is, the electric auxiliary heating element 52 is positioned downstream of the condenser 51 in the airflow direction within the airflow channel 11, allowing the airflow to be heated twice, sequentially by the condenser 51 and the electric auxiliary heating element 52. Therefore, when the condenser 51 fails to heat the air to the set temperature, the electric auxiliary heating element 52 can reheat the airflow flowing into the second air outlet channel 112b to the set temperature, ensuring that the final airflow discharged into the indoor space meets the user's required temperature, thus improving the user experience. In a specific example, the electric auxiliary heating element 52 can be a PTC heater.

[0058] For example, when a user takes a bath in winter, the airflow in the second air outlet 112b is reheated by the electric auxiliary heating element 52, so that the temperature of the airflow that is finally discharged into the indoor space through the indoor air outlet 13 is higher, so that the user can feel the warm airflow, thereby avoiding the discomfort caused by the cold air and the risk of the user catching a cold.

[0059] Furthermore, the upper end of the electric auxiliary heating element 52 abuts against the wall of the partition 16 facing the second air outlet channel 112b, and the lower end of the electric auxiliary heating element 52 abuts against the bottom of the housing 1 facing the wall of the second air outlet channel 112b. In other words, the electric auxiliary heating element 52 can be well supported between the opposing side walls of the second air outlet channel 112b in the vertical direction, thus achieving a secure installation of the electric auxiliary heating element 52 and significantly increasing the contact area between the electric auxiliary heating element 52 and the airflow within the second air outlet channel 112b, thereby improving the heating effect of the electric auxiliary heating element 52 on the airflow within the second air outlet channel 112b. Furthermore, the electric auxiliary heating element 52 is inclined relative to the airflow direction within the second air outlet channel 112b, thereby further increasing the contact area between the airflow and the electric auxiliary heating element 52, further improving the heating effect of the electric auxiliary heating element 52 on the airflow within the second air outlet channel 112b. Under the premise of the same heating effect, the power consumption of the electric auxiliary heating element 52 can be significantly reduced, resulting in energy saving and environmental protection.

[0060] According to some optional embodiments of the present invention, the dehumidification module 4 includes an evaporator 41 disposed within the air conditioning duct 111. The evaporator 41 can absorb external heat. Specifically, the evaporator 41 is located upstream of the condenser 51. By absorbing heat from the air conditioning duct 111, when airflow passes through the evaporator 41, the gaseous water in the airflow liquefies upon cooling and condenses on the evaporator 41, thereby reducing the water content in the airflow passing through the evaporator 41 to ensure that dry air can be blown into the indoor space.

[0061] Furthermore, the upper end of the evaporator 41 is flush with or lower than the upper end of the second condenser section 51b. In other words, the upper end of the evaporator 41 is not higher than the upper end of the second condenser section 51b, while the first condenser section 51a is located above the second condenser section 51b. Therefore, the evaporator 41 can effectively prevent obstruction of the airflow entering the first air outlet duct 112a, thereby reducing the flow resistance when the airflow is discharged through the first air outlet duct 112a and the first outdoor air outlet 14a, allowing the airflow to be quickly discharged through the first air outlet duct 112a and the first outdoor air outlet 14a. This effectively improves the cooling effect on the air conditioning duct 111, allowing for precise temperature control within the air conditioning duct 111, and increases the exhaust speed in exhaust mode to quickly discharge polluted air from the indoor space, thus reducing the energy consumption of the fan module 2 and promoting energy conservation and environmental protection.

[0062] Furthermore, the evaporator 41 is inclined relative to the airflow direction of the air conditioning duct 111, and the extension direction of the condenser 51 is parallel to the extension direction of the evaporator 41. This allows the airflow within the air conditioning duct 111 to increase the contact area between the air and the evaporator 41 and condenser 51, thereby improving the heat exchange efficiency between the airflow and the evaporator 41 and condenser 51. In addition, the evaporator 41 and condenser 51 can fully utilize the space in the air conditioning duct 111 in the airflow direction, and can save installation space in the vertical direction, resulting in a smaller thickness of the air conditioning unit 100. In a specific example, the air conditioning unit 100 is installed on the ceiling. The thinner air conditioning unit 100 is easier to install and can also reduce the impact of the exposed air conditioning unit 100 on the overall interior decoration style.

[0063] According to some optional embodiments of the present invention, a second outdoor air outlet 14b communicating with the second air outlet duct 112b is also formed on the housing 1. The second outdoor air outlet 14b is connected to the external space. Therefore, in the exhaust mode, the air in the indoor space can be exhausted to the external space by closing the indoor air outlet 13 and opening at least one of the first outdoor air outlet 14a and the second outdoor air outlet 14b. For example, only the first outdoor air outlet 14a can be opened so that the air in the indoor space can be exhausted to the external space through the indoor air inlet 12, the air conditioning duct 111, the first air outlet duct 112a and the first outdoor air outlet 14a. Alternatively, only the second outdoor air outlet 14b can be opened so that the air in the indoor space can be exhausted to the external space through the indoor air inlet 12, the air conditioning duct 111, the second air outlet duct 112b and the second outdoor air outlet 14b. Of course, the first outdoor air outlet 14a and the second outdoor air outlet 14b can also be opened simultaneously to improve the air exhaust efficiency.

[0064] Furthermore, the second outdoor air outlet 14b and the first outdoor air outlet 14a are located on the side wall of the housing 1 along the first direction s1, and the second outdoor air outlet 14b and the indoor air inlet 12 are respectively located on two side walls of the housing 1. That is, the first outdoor air outlet 14a and the second outdoor air outlet 14b are located on different side walls of the housing 1 from the indoor air inlet 12. This can effectively reduce the difficulty of connecting the first outdoor air outlet 14a and the second outdoor air outlet 14b with the outdoor space, and can effectively avoid airflow interference between the first outdoor air outlet 14a and the second outdoor air outlet 14b and the indoor air outlet 13.

[0065] According to some embodiments of the present invention, such as Figures 4-6As shown, the airflow channel 11 also includes an air inlet channel 113, which is located upstream of the defogging module 3 to connect the indoor air inlet 12 and the air conditioning duct 111. A fresh air inlet 15, connected to the air inlet channel 113, is also formed on the housing 1. The air conditioning device 100 also includes a fresh air duct 6, and the fresh air inlet 15 is adapted to connect with the external space through the fresh air duct 6. In other words, the air conditioning device 100 has a fresh air mode. Driven by the fan module 2, fresh air from the external space can be sequentially discharged into the indoor space through the fresh air duct 6, the fresh air inlet 15, the air inlet channel 113, the airflow channel 11, and the indoor air outlet 13, thereby effectively increasing the oxygen content in the indoor space and creating a healthy and safe breathing environment for users. Furthermore, the injection of fresh air promotes airflow, effectively improving the stuffy environment of the indoor space.

[0066] Secondly, the fresh air duct 6 effectively reduces the difficulty of connecting the fresh air inlet 15 to the external space and facilitates later maintenance and replacement. Simultaneously, the installation location of the housing 1 can be flexibly selected according to user needs. After the housing 1 is completed, the fresh air inlet 15 of the housing 1 is connected to the external space by selecting the corresponding specification of the fresh air duct 6, thus meeting different user installation requirements and adapting well to different interior layouts, making it widely applicable. In a specific example, the fresh air duct 6 is equipped with an air filtration module, which can intercept dust, particles, and germs in the external air, helping to create a healthy and safe breathing environment for users.

[0067] According to some optional embodiments of the present invention, the air conditioning device 100 further includes an exhaust duct 7 and a merging duct 8. An outdoor air outlet 14 communicating with the airflow channel 11 is also formed on the housing 1. One end of the exhaust duct 7 is connected to the outdoor air outlet 14, and the other end of the exhaust duct 7 and the end of the fresh air duct 6 away from the fresh air inlet 15 are connected to one end of the merging duct 8. The other end of the merging duct 8 is adapted to extend through the building to the external space. That is, both the fresh air duct 6 and the exhaust duct 7 are connected to the external space through the merging duct 8. When installing the air conditioning device 100, it is only necessary to drill a mounting hole in the wall of the building for the other end of the merging duct 8 to extend out. Therefore, the difficulty of connecting the fresh air duct 6 and exhaust duct 7 to the external space and the installation difficulty of the air conditioning equipment 100 can be significantly reduced. Furthermore, the separate design of the fresh air duct 6, exhaust duct 7, and integrated air duct 8 reduces the manufacturing difficulty of these components and allows for separate installation and disassembly, thus significantly reducing the difficulty of later maintenance and cleaning. In a specific example, the connection between the fresh air duct 6 and the housing 1, the connection between the exhaust duct 7 and the housing 1, and the connection between the fresh air duct 5 and the exhaust duct 7 and the integrated air duct 8 can all be achieved using snap-fit ​​connections. This further reduces the difficulty of installation and disassembly of the fresh air duct 6, exhaust duct 7, and integrated air duct 8, facilitating later maintenance and cleaning.

[0068] In addition, the airflow channel 11 can be connected to the external space through the outdoor air outlet 14, the exhaust pipe 7, and the fusion air duct 8, so that the air conditioning equipment 100 can have both fresh air mode and exhaust mode at the same time. Specifically, in exhaust mode, the fresh air inlet 15 and the indoor air outlet 13 are closed, and the indoor air inlet 12 and the outdoor air outlet 14 are opened. Driven by the fan module 2, the air in the indoor space can enter the airflow channel 11 through the indoor air inlet 12 and be discharged to the outdoor space through the outdoor air outlet 14, the exhaust pipe 7, and the fusion pipe. In fresh air mode, the fresh air inlet 15 and the indoor air outlet 13 are opened, and the indoor air inlet 12 and the outdoor air outlet 14 are closed. Driven by the fan module 2, the fresh air in the external space can enter the airflow channel 11 through the fusion air duct 8, the fresh air duct 6, and the fresh air inlet 15 and be discharged into the indoor space through the indoor air outlet 13. In addition, the exhaust mode and fresh air module can be activated simultaneously, which means opening all the fresh air inlet 15, indoor air outlet 13, indoor air inlet 12 and outdoor air outlet 14.

[0069] Furthermore, a first sub-ventilation duct 81 and a second sub-ventilation duct 82 are formed within the integrated air duct 8, separated from each other. The first sub-ventilation duct 81 is connected to the exhaust duct 7, and the second sub-ventilation duct 82 is connected to the fresh air duct 6. That is, one end of the first sub-ventilation duct 81 is connected to the exhaust duct 7, and the other end of the first sub-ventilation duct 81 is connected to the external space, thereby forming an airflow passage between the outdoor air outlet 14, the exhaust duct 7, the first sub-ventilation duct 81, and the external space, so that the airflow in the airflow passage 11 can be discharged to the external space through the outdoor air outlet 14, the exhaust duct 7, and the first sub-ventilation duct 81; one end of the second sub-ventilation duct 82 is connected to the fresh air duct 6, and the other end of the second sub-ventilation duct 82 is connected to the external space, thereby forming an airflow passage between the fresh air inlet 15, the fresh air duct 6, the second sub-ventilation duct 82, and the external space, so that fresh air from the external space can enter the airflow passage 11 through the second sub-ventilation duct 82, the fresh air duct 6, and the fresh air inlet 15.

[0070] Therefore, the airflow discharged through the first sub-ventilation duct 81 and the fresh airflow in the second sub-ventilation duct 82 can be better avoided from interfering with each other, which is conducive to improving the exhaust efficiency and the fresh air intake efficiency.

[0071] Optionally, the side of the first sub-ventilation duct 81 furthest from the exhaust duct 7 forms an exhaust port 83, and the side of the second sub-ventilation duct 82 furthest from the fresh air duct 6 forms an air inlet 84. The exhaust port 83 faces the opposite direction to the air inlet 84. In other words, the direction in which the air conditioning device 100 exhausts air into the external space is opposite to the direction in which it draws in fresh air from the external space. For example, the exhaust port 83 can face upwards while the air inlet 84 can face downwards. This effectively prevents the stale indoor air discharged through the exhaust port 83 from being re-drawn into the air inlet 84, thereby reducing the interference of exhaust air on fresh air intake and rapidly increasing the oxygen content of the indoor space.

[0072] Optionally, the first sub-ventilation duct 81 includes a first transition section 811 and an exhaust section 812. The first transition section 811 is adapted to guide the airflow in the exhaust duct 7 into the exhaust section 812. The sidewall of the first transition section 811 opposite to the exhaust duct 7 forms an arc shape. That is, one end of the first transition section 811 is connected to the end of the exhaust duct 7 away from the outdoor air outlet 14, and the other end of the first transition section 811 is connected to the exhaust section 812. When the airflow in the exhaust duct 7 blows onto the sidewall of the first transition section 811 opposite to the exhaust duct 7, the arc-shaped sidewall can effectively guide the airflow into the exhaust section 812. Thus, the airflow direction of the exhaust duct 7 can be better adjusted, and the flow resistance of the airflow from the exhaust duct 7 to the exhaust section 812 can be better reduced to ensure exhaust efficiency.

[0073] Optionally, the second sub-ventilation duct 82 includes a second transition section 821 and a fresh air section 822. The second transition section 821 is adapted to guide the airflow in the fresh air section 822 into the fresh air duct 6. The sidewalls of the second transition section 821 and the fresh air section 822 opposite to each other form an arc shape. That is, one end of the second transition section 821 is connected to the end of the fresh air duct 6 away from the fresh air inlet 15, and the other end of the second transition section 821 is connected to the fresh air section 822. When the airflow in the fresh air section 822 blows onto the sidewalls of the second transition section 821 and the fresh air section 822 opposite to each other, the arc-shaped sidewalls can better guide the airflow into the fresh air duct 6. Thus, the airflow direction of the fresh air section 822 can be better adjusted, and the flow resistance of the airflow from the fresh air section 822 to the fresh air duct 6 can be better reduced, so as to ensure the fresh air intake efficiency.

[0074] Furthermore, the ventilation area of ​​the exhaust section 812 is larger than that of the fresh air section 822. This means that the exhaust section 812 is more efficient at removing indoor air than the fresh air section 822 is at introducing fresh air into the room. Therefore, the exhaust section 812 can quickly remove stale air from the indoor space while effectively controlling the amount of fresh air entering, resulting in a gentler fresh air intake for users and avoiding discomfort caused by large amounts of air blowing directly on them.

[0075] According to some embodiments of the present invention, the defogging module 3 includes a plurality of folded plates 31 that are wavy and bent along the airflow direction. The plurality of folded plates 31 are arranged at intervals in the second direction s2, and a defogging channel 32 is defined between any adjacent folded plates 31. That is, the defogging module 3 has a plurality of defogging channels 32 arranged in the second direction s2, so that the airflow entering the airflow channel 11 through the indoor air inlet 12 can be divided into multiple streams at the defogging module 3 and enter the plurality of defogging channels 32 respectively. When the airflow carrying mist flows through the defogging channel 32, it impacts the wavy protrusions on the folded plates 31, so that the folded plates 31 can intercept water droplets in the airflow, thereby removing liquid water from the airflow. This can significantly improve the defogging efficiency and quality of the defogging module.

[0076] According to some optional embodiments of the present invention, the dehumidification module 4 includes an evaporator 41, which is inclined relative to the airflow direction, and the plane of the downstream side of the plurality of baffles 31 is parallel to the extension direction of the evaporator 41. This allows the airflow to flow within the airflow channel 11, thereby increasing the contact area between the air and the evaporator 41 and improving the heat exchange efficiency between them. Furthermore, it allows the evaporator 41 to fully utilize the space of the airflow channel 11 in the airflow direction and saves space occupied by the evaporator 41 in the vertical direction, allowing the air conditioning device 100 to have a smaller thickness, thus saving installation space and reducing the impact on the cleanliness of the indoor space.

[0077] According to some embodiments of the present invention, the air conditioning device 100 further includes a compressor 9, the fan module 2 includes a fan wheel 21 and a volute 22, the fan wheel 21 is disposed inside the volute 22, the volute 22 cooperates with the housing 1 to define an airflow channel 11, the compressor 9 is disposed inside the housing 1 and is located outside the airflow channel 11, the compressor 9 is disposed on one side of the volute 22 along the first direction s1, the demisting module 3, the dehumidifying module 4 and the heating module 5 are disposed on the other side of the volute 22 along the first direction s1, and the compressor 9, the fan module 2, the demisting module 3, the dehumidifying module 4 and the heating module 5 are arranged along the first direction s1. This allows the compressor 9, fan module 2, demisting module 3, dehumidifying module 4, and heating module 5 to fully utilize the space inside the housing 1 in the first direction s1, thus saving space occupied by the compressor 9, fan module 2, demisting module 3, dehumidifying module 4, and heating module 5 in the vertical direction. This results in a smaller thickness for the air conditioning unit 100, further saving installation space and reducing its impact on the cleanliness of the indoor space. Furthermore, the fan module 2 includes a motor that drives the impeller 21 to rotate.

[0078] Furthermore, both the indoor air inlet 12 and the indoor air outlet 13 are located on the bottom wall of the housing 1. This means that air from the indoor space can flow upwards through the indoor air inlet 12 into the airflow channel 11, be processed by the defogging module 3, dehumidifying module 4, and heating module 5, and then be discharged downwards into the indoor space through the indoor air outlet 13. In a specific example, the air conditioning unit 100 can be installed on the ceiling. Therefore, when installing the air conditioning unit 100, only openings exposing the indoor air inlet 12 and indoor air outlet 13 need to be provided on the ceiling, thereby reducing the impact of the air conditioning unit 100 on the cleanliness of the interior decoration.

[0079] Furthermore, the housing 1 has a fresh air inlet 15 and an outdoor air outlet 14 that communicate with the external space and the airflow channel 11. The volute 22 has a first volute inlet 221 that communicates with the indoor air inlet 12, a second volute inlet that communicates with the fresh air inlet 15, and a volute outlet 222 that is opposite to the defogging module 3. That is, the indoor air inlet 12 is connected to the air duct inside the volute 22 through the first volute inlet 221, and the fresh air inlet 15 is connected to the air duct inside the volute 22 through the second volute inlet. Driven by the impeller 21, the air in the indoor space can enter the air duct inside the volute 22 through the indoor air inlet 12 and the first volute inlet 221, and the fresh air in the external space can enter the air duct inside the volute 22 through the fresh air inlet 15 and the second volute inlet. The airflow inside the volute 22 can be blown towards the defogging module 3 through the volute outlet 222 under the drive of the impeller 21. Therefore, the fan module 2 can be better guaranteed to smoothly introduce airflow from the fresh air inlet 15 and the indoor air inlet 12, while preventing the airflow in the fresh air inlet 15 and the airflow in the indoor air inlet 12 from interfering with each other.

[0080] Furthermore, the indoor air inlet 12, the fresh air inlet 15, and the outdoor air outlet 14 are respectively located on three different side walls of the housing 1. This effectively avoids interference between the indoor air inlet 12, the fresh air inlet 15, and the outdoor air outlet 14. In some alternative embodiments, one of the fresh air inlet 15 and the outdoor air outlet 14 is located on the side wall of the air conditioning unit 100 closest to the wall, while the other is located on another side wall of the air conditioning unit 100. This facilitates communication between the fresh air inlet 15 and the outdoor air outlet 14 and the external space, without interfering with the indoor air inlet 12 and the indoor air outlet 13 located on the bottom wall of the housing 1. The fresh air inlet 15 can communicate with the external space through the fresh air duct 6, and the outdoor air outlet 14 can communicate with the external space through the exhaust duct 7. Therefore, when the air conditioning unit 100 is installed on the ceiling, the exhaust duct 7 and the fresh air duct 6 can be effectively prevented from being exposed, ensuring the neatness of the interior decoration.

[0081] The following is for reference. Figures 1-6 An air conditioning device 100 according to a specific embodiment of the present invention is described.

The volute 22 and the inner wall of the housing 1 together define an airflow channel 11. The airflow channel 11 includes an air inlet channel 113, an air conditioning duct 111, and an air outlet channel 112 connected in sequence. The housing 1 is also provided with a partition 16, which extends along the first direction s1 to divide the air outlet channel 112 into a first air outlet channel 112a and a second air outlet channel 112b that are separated vertically. The volute 22 forms a first volute inlet 221, a second volute inlet, and a volute outlet 222. The housing 1 forms a structure located along the first direction s1. An outdoor air outlet 14 is located on one side wall, an indoor air inlet 12 and an indoor air outlet 13 are located on the bottom wall, and a fresh air inlet 15 is located on one side wall in the second direction s2. The second direction s2 is perpendicular to the first direction s1 and is also perpendicular to the vertical direction. The indoor air inlet 12 is connected to the first volute inlet 221, and the fresh air inlet 15 is connected to the second volute inlet. An air intake channel 113 is formed inside the volute 22.

[0084] Furthermore, the outdoor air outlet 14 includes a first outdoor air outlet 14a and a second outdoor air outlet 14b. The first outdoor air outlet 14a is connected to the first air outlet channel 112a, and the second outdoor air outlet 14b is connected to the second air outlet channel 112b. The first outdoor air outlet 14a is located above the second outdoor air outlet 14b. The exhaust pipe 7 is connected to the first outdoor air outlet 14a and the second outdoor air outlet 14b at one end near the housing 1. The fresh air pipe 6 is connected to the fresh air inlet 15 at one end near the housing 1. The fusion duct 8 is located on one side adjacent to the outdoor air outlet 14. The fusion duct 8 includes a first sub-ventilation pipe 81 and a second sub-ventilation pipe 82 spaced apart. The first sub-ventilation pipe 81 includes a connection to a first transition section 811 and a... The exhaust section 812 has an exhaust duct 7 whose end away from the outdoor air outlet 14 is connected to the end of the first transition section 811 whose end is away from the exhaust section 812. An exhaust outlet 83 is formed on the side of the exhaust section 812 away from the first transition section 811. The second sub-ventilation duct 82 includes a second transition section 821 and a fresh air section 822. The end of the fresh air duct 6 whose end is away from the fresh air inlet 15 is connected to the end of the second transition section 821 whose end is away from the fresh air section 822. An air inlet 84 is formed on the side of the fresh air section 822 whose end is away from the second transition section 821. The flow area of ​​the fresh air duct 6 and the exhaust section 812 is larger than the flow area of ​​the fresh air section 822. The flow area of ​​the exhaust section 812 is larger than the flow area of ​​the exhaust section 812. The exhaust outlet 83 and the air inlet 84 face opposite directions.

[0085] The defogging module 3 and the dehumidifying module 4 are both located in the air conditioning duct 111. The upstream side of the defogging module 3 is opposite to the volute outlet 222. The defogging module 3 includes multiple folding plates 31 arranged at intervals along the second direction s2. Each folding plate 31 is wavy in the first direction s1 (i.e., the airflow direction in the air conditioning duct 111). A defogging channel 32 is formed between two adjacent folding plates 31. The dehumidifying module 4 includes an evaporator 41, which is located on the downstream side of the defogging channel 32. The evaporator 41 extends upward at an angle in the direction away from the defogging module 3. The plane on the downstream side of the multiple folding plates 31 is parallel to the extension direction of the evaporator 41. In addition, the heating module 5 includes a condenser 51 and an electric auxiliary heating element 52. The condenser 51 is located in the air conditioning duct 111 and downstream of the evaporator 41 and is arranged parallel to the evaporator 41. The compressor 9 is connected to the evaporator 41 and the condenser 51. The compressor 9, the fan module 2, the evaporator 41 and the condenser 51 are arranged along the first direction s1. The compressor 9 is located in the housing 1 and on the side of the fan module 2 away from the evaporator 41 in the first direction s1.

[0086] Furthermore, the condenser 51 includes a first condensing section 51a opposite to the first air outlet channel 112a and a second condensing section 51b opposite to the second air outlet channel 112b. The side of the condenser 51 away from the evaporator 41 abuts against the end of the partition plate 16 away from the housing 1 in the first direction s1. The upper end of the evaporator 41 is flush with the upper end of the second condensing section 51b. The electric auxiliary heating element 52 is disposed in the second air outlet channel 112b and is inclined relative to the vertical direction.

[0087] The air conditioning unit 100 has a defogging heating mode, a dehumidification mode, an exhaust mode, and a fresh air mode.

[0088] Specifically, in the defogging and heating mode, the indoor air inlet 12 and indoor air outlet 13 are opened, while the fresh air inlet 15, the first outdoor air outlet 14a, and the second outdoor air outlet 14b are closed. The impeller 21 drives the air in the indoor space to enter the air conditioning duct 111 through the indoor air inlet 12, the first volute inlet 221, and the volute outlet 222. The air passes through the defogging module 3, the evaporator 41, and the second condenser 51b in sequence. The defogging module 3 removes the fog in the air, the evaporator 41 condenses and liquefies the gaseous water in the air, and the condenser 51 heats the air to obtain dry and warm air. The air continues to flow into the second air outlet duct 112b. When the heating temperature of the air is lower than the user-set value, the air is reheated to the set value by the electric auxiliary heating element 52 and discharged into the indoor space through the indoor air outlet 13.

[0089] In dehumidification mode, the indoor air inlet 12, indoor air outlet 13, and first outdoor air outlet 14a are opened, while the fresh air inlet 15 and second outdoor air outlet 14b are closed. The impeller 21 drives the air in the indoor space to enter the air conditioning duct 111 through the indoor air inlet 12, the first volute inlet 221, and the volute outlet 222. The air passes through the demisting module 3, the evaporator 41, and the condenser 51 in sequence. The demisting module 3 removes the mist in the air, and the evaporator 41 condenses and liquefies the gaseous water in the air. The airflow flowing into the first air outlet duct 112a carries away some of the heat in the air conditioning duct 111 and the first condenser 51a, and is discharged to the outdoor space through the first outdoor air outlet 14a, the exhaust pipe 7, and the first sub-ventilation pipe 81, thereby controlling the temperature of the airflow flowing into the second air outlet duct 112b. The airflow in the second air outlet duct 112b is discharged into the indoor space through the indoor air outlet 13, thereby achieving dehumidification of the indoor space and keeping the indoor temperature from rising.

[0090] In exhaust mode, the indoor air inlet 12, the first outdoor air outlet 14a, and the second outdoor air outlet 14b are opened, while the fresh air inlet 15 and the indoor air outlet 13 are closed. The impeller 21 drives the air in the indoor space to enter the air conditioning duct 111 through the indoor air inlet 12, the first volute inlet 221, and the volute outlet 222, and continues to flow into the air outlet duct 112. The airflow flowing towards the first air outlet duct 112a is discharged into the exhaust pipe 7 through the first outdoor air outlet 14a, and the airflow flowing towards the second air outlet duct 112b is discharged into the pipe through the second outdoor air outlet 14b. The airflow entering the exhaust pipe 7 is discharged to the outdoor space through the first sub-ventilation pipe 81 and the exhaust outlet 83.

[0091] In fresh air mode, the fresh air inlet 15 and indoor air outlet 13 are open, while the indoor air inlet 12, first outdoor air outlet 14a, and second outdoor air outlet 14b are closed. Driven by the impeller 21, fresh air from the outside space is exhausted into the indoor space through the air inlet 84, first sub-ventilation duct 81, fresh air duct 6, fresh air inlet 15, airflow channel 11, and indoor air outlet 13. The outside air can be dehumidified or heated by the dehumidification module 4 and heating module 5 according to user settings before being exhausted into the indoor space. Furthermore, both exhaust and fresh air modes can be activated simultaneously, meaning the fresh air inlet 15, indoor air outlet 13, indoor air inlet 12, first outdoor air outlet 14a, and second outdoor air outlet 14b are all open.
