Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] An air conditioner, or air conditioner, is a device used to regulate and control indoor environmental parameters (such as temperature, humidity, cleanliness, and airflow) to meet people's needs for a comfortable indoor environment or the requirements of specific processes.

[0003] During air conditioning operation, whether in cooling or heating mode, indoor air humidity may decrease, causing people to feel dry and uncomfortable, and potentially leading to problems such as dry skin and respiratory illnesses. Therefore, air conditioners are equipped with a steam humidification module, which delivers water vapor into the room to increase indoor air humidity and improve indoor comfort.

[0004] In related technologies, to allow users to more intuitively understand the air humidification process, some air conditioners incorporate a visual enclosure within the unit casing, through which the steam pipe of the steam humidification module passes. This allows users to clearly see whether the humidification function is activated. However, this design also has drawbacks; impurities or backflow liquid from the humidification outlet can pass through the visual enclosure, resulting in a poor user experience. Summary of the Invention

[0005] This application discloses an indoor air conditioning unit that avoids the problem of impurities or backflow liquid from the humidification outlet passing through the visualization housing, ensuring the cleanliness and aesthetics of the interior of the visualization housing, providing users with a better observation experience, and also reducing the impact of impurities or backflow liquid on the visualization effect.

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

[0007] The housing has an air outlet and a humidification outlet, and the housing includes:

[0008] Front panel, the front panel including a transparent area;

[0009] A heat exchanger, wherein the heat exchanger is disposed within the housing;

[0010] The first fan is located inside the casing. The first fan is used to introduce gas into the casing and exchange the gas through the heat exchanger before sending it out through the air outlet.

[0011] An air humidification module, disposed within the housing, comprising:

[0012] A steam generating device for converting water into steam;

[0013] A visualization housing, at least a portion of which is a transparent structure corresponding to a transparent area, so that water vapor located within the visualization housing can be observed;

[0014] A humidifying tube is configured to direct a portion of the water vapor to the visual housing and another portion of the water vapor to the humidifying outlet.

[0015] In this way, the water vapor generated by the steam generator is divided into two parts, which are guided to the receiving cavity of the visualization housing and the humidification outlet, respectively, achieving a reasonable distribution of water vapor. On the one hand, this meets the user's need to observe the humidification process, and on the other hand, it ensures that enough water vapor can be discharged into the room, effectively increasing the humidity of the indoor air, improving indoor comfort, and avoiding the problem of impurities or backflow liquid from the humidification outlet passing through the visualization housing, thus ensuring the cleanliness and aesthetics of the interior of the visualization housing and providing users with a better observation experience.

[0016] This application also provides an indoor unit for an air conditioner, comprising:

[0017] The housing has an air outlet and a humidification outlet, and the housing includes:

[0018] Front panel, the front panel including a transparent area;

[0019] A heat exchanger located within the housing;

[0020] The first fan is located inside the casing. The first fan is used to introduce gas into the casing and exchange the gas through the heat exchanger before sending it out through the air outlet.

[0021] An air humidification module, disposed within the housing, comprising:

[0022] A steam generating device for converting water into steam;

[0023] A humidifying pipe is connected to the water vapor generating device to guide the water vapor to the air outlet;

[0024] A visualization housing, which is connected to the humidification pipe, wherein at least a portion of the visualization housing is a transparent structure so that water vapor located inside the visualization housing can be observed;

[0025] The humidification tube includes:

[0026] A first humidifying tube, one end of which is connected to the water vapor generating device, and the other end of which is connected to the visual housing;

[0027] The second humidification tube has one end connected to the water vapor generating device and the other end connected to the humidification outlet.

[0028] Thus, by setting up a first humidification pipe and a second humidification pipe, water vapor is guided to the visualization housing and the humidification outlet respectively, achieving a reasonable distribution of water vapor. This satisfies the user's need to observe the humidification process while ensuring sufficient water vapor is discharged into the room, effectively increasing indoor air humidity and improving indoor comfort. Therefore, compared to existing technologies, this structure avoids the problem of impurities or backflow liquid from the humidification outlet passing through the visualization housing, ensuring the cleanliness and aesthetics of the interior of the visualization housing, providing users with a better observation experience, and reducing the impact of impurities or backflow liquid on the visualization effect.

[0029] This application also provides an air conditioning indoor unit, wherein the humidification pipe further includes:

[0030] The humidification main pipe has its inlet end connected to the water vapor generating device, and its outlet end connected to the inlet end of the first humidification pipe and the inlet end of the second humidification pipe, respectively.

[0031] In this way, the humidification main pipe can synchronously distribute the water vapor generated by the water vapor generator to the first humidification pipe and the second humidification pipe, ensuring that the water vapor leading to the visualization shell and the humidification outlet is relatively stable and synchronous. The humidification main pipe can also serve as a buffer zone to mitigate the impact of pressure fluctuations of the water vapor generator on the first and second humidification pipes. It will not occupy too much unnecessary space, allowing for a more compact arrangement of the pipeline, reducing the space occupied by other components, and improving space utilization.

[0032] This application also provides an air conditioning indoor unit, wherein the humidification pipe further includes a three-way pipe, the three-way pipe comprising:

[0033] The first pipe connector is connected to the outlet end of the humidification main pipe;

[0034] The second pipe connector is connected to the inlet end of the first humidifying pipe;

[0035] The third pipe connector is connected to the inlet end of the second humidification pipe.

[0036] In this way, the three-way pipe acts as a stable flow distribution structure, stably distributing water vapor in the main humidification pipe to the first and second humidification pipes, providing two clear and fixed flow channels for water vapor. No additional switching devices or complex control logic are required. The three pipe joints of the three-way pipe are tightly connected to the corresponding pipes, forming a relatively closed and stable connection structure, which can better ensure the sealing of the connection, effectively reduce the possibility of water vapor leakage, and improve the reliability and stability of the humidification system.

[0037] This application also provides an air conditioning indoor unit, wherein the diameter of the first humidifying pipe is smaller than the diameter of the second humidifying pipe.

[0038] Thus, the diameter of the first humidifying tube is smaller than that of the second humidifying tube. The smaller diameter of the first humidifying tube results in a narrower internal channel, limiting the amount of water vapor passing through. This allows for guiding a suitable amount of water vapor to the visible housing, facilitating user observation of the water vapor's state and preventing large amounts of water vapor from accumulating there. The larger diameter of the second humidifying tube provides a wider channel, enabling the delivery of a larger amount of water vapor to the humidification outlet, thus meeting the need for effective humidification of indoor air.

[0039] This application also provides an indoor air conditioning unit, wherein the diameter of the first humidifying pipe and the diameter of the second humidifying pipe are 10-30 mm.

[0040] Thus, the diameters of the first and second humidifying pipes are both within the range of 10-30mm, neither too large nor too small, ensuring sufficient water vapor delivery while adapting to the spatial layout of the air conditioner's indoor unit. Within this 10-30mm diameter range, the humidifying pipes guarantee a stable output of water vapor. The pipe diameter will not be too small, leading to water vapor blockage or unstable flow, nor too large, causing excessive fluctuations in water vapor pressure. This helps maintain the stability of the humidification function of the air conditioner's indoor unit, keeping indoor humidity at a relatively stable level and providing users with a comfortable indoor environment.

[0041] This application also provides an air conditioner indoor unit, wherein a decorative cavity is formed in the portion of the housing corresponding to the transparent area, the decorative cavity comprising:

[0042] The front side is transparent;

[0043] The rear side panel corresponds to the transparent area along the front-rear direction of the indoor air conditioner unit. The rear side panel is provided with a through hole, and the transparent part of the visualization housing is disposed in the through hole so that water vapor located in the visualization housing can be observed through the transparent area and the decorative cavity.

[0044] In this way, a decorative cavity is set inside the casing. The front side of the decorative cavity is transparent, forming a continuous transparent observation area together with the transparent part of the visual housing. The rear panel is located at the rear of the decorative cavity, corresponding to the transparent area of ​​the indoor unit in the front-back direction. The transparent part of the visual housing is located in the through hole of the rear panel, realizing the connection between the visual housing and the decorative cavity. This combines the function of observing water vapor with the decorative function, achieving multiple functions within the limited casing space. It does not occupy too much space and provides users with a unique visual experience. At the same time, the transparent part of the visual housing is located in the through hole, which is equivalent to adding a support point to the rear panel of the decorative cavity, which helps to enhance the connection strength between the decorative cavity and the visual housing. This makes the entire structure more stable when subjected to external forces, less prone to deformation or damage, and improves the durability of the product.

[0045] This application also provides an air conditioner indoor unit, wherein the air humidification module further includes:

[0046] A light-emitting element is disposed on the side of the visualization housing opposite to the decorative cavity.

[0047] In this way, the light-emitting element is set on the side of the visualization shell away from the decorative cavity. The light emitted by the element can directly act on the visualization shell and the water vapor inside. The light emitted by the element can pass through the visualization shell and illuminate the water vapor inside, making the water vapor more clearly visible under the light. In addition, the light may also pass through the transparent part of the visualization shell and the connection between it and the decorative cavity, creating a certain light and shadow effect inside the decorative cavity, which together with the overall structure creates a unique visual atmosphere.

[0048] This application also provides an air conditioner indoor unit, wherein the rear panel includes a light-transmitting area that extends along the length of the air conditioner indoor unit;

[0049] The light-emitting element includes a light strip body that extends along the length of the indoor unit of the air conditioner and along the front-back direction of the indoor unit of the air conditioner, and the light strip body corresponds to the light-transmitting area.

[0050] In this way, the light strip extends along the length direction and corresponds to the light-transmitting area, which can provide relatively uniform basic lighting for the interior of the decorative cavity, thereby showcasing the decorative environment inside the cavity. The light strip is arranged along the length direction and works in conjunction with the light-transmitting area of ​​the rear panel to achieve large-area lighting without taking up too much extra space.

[0051] This application also provides an air conditioner indoor unit, wherein the light-emitting element further includes a light strip extension, the light strip extension is connected to the light strip body, the light strip extension extends along the height direction of the air conditioner indoor unit and along the front-rear direction of the air conditioner indoor unit, the light strip extension corresponds to the visual housing.

[0052] In this way, the light strip extension illuminates the visual housing, allowing the water vapor inside the housing to be clearly illuminated. Since the light strip extends in both length and height, it makes full use of the space inside the air conditioner indoor unit. The combination of the light strip body and the light strip extension ensures that the decorative cavity has a certain brightness while highlighting the observation area of ​​the visual housing, allowing users to observe the generation and flow of water vapor more clearly, enhancing the visualization effect, and making the layout of each component more compact and reasonable, thus improving space utilization.

[0053] This application also provides an indoor air conditioning unit, wherein the water vapor generating device includes an evaporative humidifier or an ultrasonic humidifier.

[0054] Evaporative humidifiers convert water into water vapor through natural evaporation, releasing the vapor slowly and evenly into the air. This results in a more natural humidification effect, stabilizing air humidity and preventing sudden spikes in localized humidity levels. It helps maintain indoor humidity levels closer to those in the natural environment, reducing indoor environmental problems caused by over-humidification or uneven humidification. Ultrasonic humidifiers, on the other hand, convert electrical energy into high-frequency mechanical vibrations using an ultrasonic transducer. These vibrations break water into tiny droplets, forming a mist. They can convert large amounts of water into mist in a short time, rapidly increasing air humidity. This method is highly efficient, and the resulting mist particles are extremely fine, dispersing more evenly in the air and mixing thoroughly for a more significant humidification effect.

[0055] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0056] This application provides an indoor air conditioning unit, including a casing, a heat exchanger, a first fan, and an air humidification module. The front panel of the casing has a transparent area, and the casing has an air outlet and a humidification outlet. Specifically, the air humidification module includes a water vapor generating device, a viewing housing, and a humidification pipe. The water vapor generating device converts water into water vapor. The humidification pipe is connected to the water vapor generating device. A receiving cavity is formed inside the viewing housing, and the receiving cavity is connected to the humidification pipe. At least a portion of the viewing housing is a transparent structure, corresponding to a transparent area. The humidification pipe guides a portion of the water vapor generated by the steam generating device into the receiving cavity so that the water vapor in the receiving cavity can be observed. The humidification pipe guides another portion of the water vapor generated by the steam generating device to the humidification outlet and releases it into the room, thereby increasing the humidity of the indoor air. In this way, the water vapor generated by the steam generating device is divided into two parts and guided to the receiving cavity of the viewing housing and the humidification outlet, respectively, achieving a reasonable distribution of water vapor. On the one hand, it meets the user's need to observe the humidification process; on the other hand, it ensures that sufficient water vapor can be discharged into the room, effectively increasing the humidity of the indoor air and improving indoor comfort. Therefore, compared with existing technologies, this structure avoids the problem of impurities or backflow liquid from the humidification outlet passing through the visualization housing, ensuring the cleanliness and aesthetics of the interior of the visualization housing, providing users with a better observation experience, and also reducing the impact of impurities or backflow liquid on the visualization effect.

Detailed Implementation

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0081] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0084] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0085] In modern life, air conditioning has long been an indispensable part of people's living and working environments. An air conditioner, also known as an air conditioner, is a device used to regulate and control indoor environmental parameters (such as temperature, humidity, cleanliness, airflow, etc.) to meet people's needs for a comfortable indoor environment or the requirements of specific processes.

[0086] During air conditioning operation, especially in cooling or heating mode, indoor air humidity may decrease, causing people to feel dry and uncomfortable, and may even lead to problems such as dry skin and respiratory illnesses. Therefore, air conditioner indoor units are equipped with steam humidification modules. The function of the steam humidification module is to deliver water vapor into the room, increase indoor air humidity, and improve indoor comfort.

[0087] An air conditioner indoor unit includes a casing, heat exchanger, fan, drainage system, and control system. The casing is typically made of plastic or metal, serving to protect internal components and for aesthetic purposes. The casing has air inlets and outlets; the inlet is usually located on the top or side to draw in indoor air, while the outlet is located on the front or bottom to expel the treated air. The heat exchanger, consisting of an evaporator (for cooling) and a condenser (for heating), is the core component for heat exchange. The fan drives airflow, allowing indoor air to pass through the heat exchanger for heat exchange. The drainage system removes condensate that forms on the evaporator surface during cooling. The control system includes control circuit boards, sensors, and a remote control, used to control the air conditioner's operating mode, temperature adjustment, fan speed adjustment, and other functions.

[0088] In related technologies, to allow users to more intuitively understand the air humidification process, some air conditioners incorporate a visual enclosure within the unit casing, through which the steam pipe of the steam humidification module passes. This allows users to clearly see whether the humidification function is activated. However, this design also has drawbacks; impurities or backflow liquid from the humidification outlet can pass through the visual enclosure, resulting in a poor user experience.

[0089] Based on this, this application provides an indoor air conditioning unit that can avoid the problem of impurities or backflow liquid from the humidification outlet passing through the visualization housing, ensuring the cleanliness and aesthetics of the interior of the visualization housing, providing users with a better observation experience, and also reducing the impact of impurities or backflow liquid on the visualization effect.

[0090] The following will describe specific embodiments and appendices. Figure 1 To be continued Figure 18 The technical solution of the air conditioner indoor unit 100 of this application will be further explained.

[0091] Please see Figure 1 One embodiment of this application provides an air conditioner indoor unit 100, which includes a housing 10. The housing 10 serves as the outer shell of the entire indoor unit, providing installation space and protection for other components, while also possessing a certain degree of decorativeness to integrate into different interior decoration styles.

[0092] Please see Figure 2 The housing 10 is equipped with an air outlet 11 and a humidification outlet 12. The air outlet 11 delivers the air processed by the heat exchanger to the indoor space. The design of the air outlet 11 typically considers factors such as the air outlet angle, wind speed, and uniformity of airflow to ensure effective circulation and regulation of indoor air. The humidification outlet 12 is used to release water vapor generated by the air humidification module 20 into the room, thereby increasing the humidity of the indoor air.

[0093] Please see Figure 3 The housing 10 includes a front panel 13, which includes a transparent area 131. The transparent area 131 is typically made of a high-strength, high-transparency material, such as glass or plastic, providing a viewing window for the user.

[0094] The indoor unit 100 of the air conditioner includes a heat exchanger (not shown in the figure), which is located inside the casing 10. The heat exchanger is the core component for temperature regulation in the indoor unit 100. The heat exchanger mainly consists of copper tubes and aluminum foil fins. In cooling mode, liquid refrigerant flows through the copper tubes of the heat exchanger, absorbing heat from the indoor air and evaporating into a gaseous state, thereby lowering the indoor air temperature. In heating mode, the flow direction of the refrigerant is changed by a four-way valve, and the function of the heat exchanger changes. The gaseous refrigerant condenses into a liquid state in the copper tubes, releasing heat and heating the indoor air.

[0095] The indoor unit 100 of the air conditioner also includes a first fan (not shown in the figure). The first fan is located inside the casing 10. The first fan is used to introduce gas into the casing 10 and, after the gas is exchanged through a heat exchanger, to be sent out through the air outlet 11. The first fan is driven by a motor to rotate an impeller, generating a strong suction force to introduce indoor gas into the casing 10. Then, it pushes the gas through the heat exchanger, allowing the gas to fully exchange heat with the heat exchanger. Finally, the treated air is sent out into the room through the air outlet 11, realizing indoor air circulation and temperature regulation.

[0096] Please see Figure 3The indoor unit 100 of the air conditioner also includes an air humidification module 20, which is located inside the casing 10. The air humidification module 20 includes a water vapor generating device 24, which is used to convert water into water vapor. It generally includes components such as a water tank, a heating element (or an ultrasonic generator), and a water level sensor. The water tank stores water and provides a water source for water vapor generation. The heating element or ultrasonic generator is responsible for converting water into water vapor, and the water level sensor monitors the water level in the tank. When the water level is too low, it sends a signal to remind the user to add water.

[0097] The air humidification module 20 also includes a visualization housing 21, within which a receiving cavity 211 is formed. At least a portion of the visualization housing 21 is transparent, corresponding to the transparent area 131, allowing the water vapor within the receiving cavity 211 to be observed. The visualization housing 21, used to contain water vapor supplied from the water vapor generating device 24, has at least a transparent portion, ensuring that the user can clearly observe the situation within the receiving cavity 211. Through the transparent area 131 of the front panel 13 of the housing 10 and the transparent structure of the visualization housing 21, the user can intuitively see the generation, flow, and state changes of water vapor within the receiving cavity 211, thereby understanding whether the air conditioner's humidification function is operating normally.

[0098] Please see Figure 4 The air humidification module 20 also includes a humidification pipe 23, which is connected to the water vapor generating device 24. The humidification pipe 23 can guide a portion of the water vapor to the receiving cavity 211 and guide another portion of the water vapor to the humidification outlet 12.

[0099] In some embodiments, please refer to Figure 4 The humidifying pipe 23 includes a first humidifying pipe 231, one end of which is connected to the water vapor generating device 24, and the other end is connected to the receiving cavity 211 of the visualization housing 21. By guiding a portion of the water vapor to the visualization housing 21, the user's need to observe the humidification process is met, allowing the user to observe the state of the water vapor through the transparent area 131 of the front panel 13, and intuitively understand whether the air conditioner's humidification function is operating normally.

[0100] In some embodiments, please refer to Figure 4 The humidifying pipe 23 also includes a second humidifying pipe 232, one end of which is connected to the water vapor generating device 24, and the other end is connected to the humidifying outlet 12. The second humidifying pipe 232 guides another portion of the water vapor generated by the water vapor generating device 24 to the humidifying outlet 12, and finally discharges the water vapor into the room, thereby humidifying the indoor air.

[0101] Thus, by setting up the first humidification pipe 231 and the second humidification pipe 232, water vapor is guided to the visualization housing 21 and the humidification outlet 12 respectively, achieving a reasonable distribution of water vapor. This satisfies the user's need to observe the humidification process while ensuring sufficient water vapor is discharged into the room, effectively increasing indoor air humidity and improving indoor comfort. Therefore, compared to existing technologies, this structure avoids the problem of impurities or backflow liquid from the humidification outlet 12 passing through the visualization housing 21, ensuring the cleanliness and aesthetics of the interior of the visualization housing 21, providing users with a better observation experience, and also reducing the impact of impurities or backflow liquid on the visualization effect.

[0102] It should be explained that the visible housing 21 is provided with a connection port that passes through the receiving cavity 211. The connection port is used to communicate with the first humidification pipe 231, and the rest of the receiving cavity 211 is a sealed structure.

[0103] The humidification tube 23 is usually made of materials such as plastic or rubber, and has good flexibility and sealing properties.

[0104] In the diagram, the X direction is the front-to-back direction of the air conditioner indoor unit 100, the Y direction is the length direction of the air conditioner indoor unit 100, and the Z direction is the height direction of the air conditioner indoor unit 100.

[0105] In some embodiments, please refer to Figures 4 to 5 The humidifying pipe 23 also includes a humidifying main pipe 233, the inlet end of which is connected to the water vapor generating device 24, and the outlet end of which is connected to the inlet end of the first humidifying pipe 231 and the inlet end of the second humidifying pipe 232 respectively.

[0106] Thus, the inlet end of the humidification main pipe 233 is connected to the water vapor generating device 24, and the outlet end of the humidification main pipe 233 is connected to the inlet ends of the first humidification pipe 231 and the second humidification pipe 232 respectively. As a key hub for water vapor transportation, the humidification main pipe 233 collects the water vapor generated by the water vapor generating device 24 and then distributes it stably to the first humidification pipe 231 and the second humidification pipe 232, realizing the unified allocation and distribution of water vapor, making the structure of the entire humidification system clearer and more reasonable, and the connection between the components more orderly.

[0107] Thus, one end of the first humidifying pipe 231 is connected to the main humidifying pipe 233, and the other end is connected to the visual housing 21. It is responsible for guiding some water vapor to the visual housing 21 so that the user can easily observe the humidification status. One end of the second humidifying pipe 232 is connected to the main humidifying pipe 233, and the other end is connected to the humidification outlet 12. It delivers another part of the water vapor to the humidification outlet 12 and releases it into the room to humidify the air.

[0108] Meanwhile, the humidification main pipe 233 can synchronously distribute the water vapor generated by the water vapor generator 24 to the first humidification pipe 231 and the second humidification pipe 232, ensuring that the water vapor leading to the visualization housing 21 and the humidification outlet 12 is relatively stable and synchronized, thus improving the stability and reliability of the entire humidification system. During operation, the internal pressure of the water vapor generator 24 may fluctuate. The humidification main pipe 233 can also act as a buffer zone, temporarily storing a certain amount of water vapor during the water vapor generation process, mitigating the impact of pressure fluctuations in the water vapor generator 24 on the first humidification pipe 231 and the second humidification pipe 232.

[0109] Furthermore, only one connection port is needed between the humidification main pipe 233 and the water vapor generating device 24. The humidification main pipe 233 is then connected to the first humidification pipe 231 and the second humidification pipe 232. This layout is simpler and clearer, facilitating installation and subsequent maintenance. Centralized distribution of water vapor through the humidification main pipe 233 does not occupy much unnecessary space, allowing for a more compact piping arrangement, reducing the space occupied by other components, and improving space utilization.

[0110] In other embodiments, the water vapor generating device 24 may also have two outlets, with the first humidifying pipe 231 and the second humidifying pipe 232 respectively connected to the two outlets.

[0111] In some embodiments, please refer to Figures 6 to 7 The humidifying pipe 23 also includes a three-way pipe 234, which includes a first pipe connector 2341 connected to the outlet end of the humidifying main pipe 233.

[0112] In some embodiments, please refer to Figures 6 to 7 The second pipe connector 2342 is connected to the inlet end of the first humidification pipe 231.

[0113] In some embodiments, please refer to Figures 6 to 7 The third pipe connector 2343 is connected to the inlet end of the second humidification pipe 232.

[0114] Thus, the three-way pipe 234 is connected to the outlet end of the humidification main pipe 233 through the first pipe connector 2341, serving to receive the water vapor delivered by the humidification main pipe 233. Then, it is connected to the inlet end of the first humidification pipe 231 through the second pipe connector 2342, guiding the water vapor towards the direction of the visible housing 21. Finally, it is connected to the inlet end of the second humidification pipe 232 through the third pipe connector 2343, delivering the water vapor towards the direction of the humidification outlet 12.

[0115] In this way, the connection method of the entire humidification pipe 23 makes the water flow path of the entire humidification pipe 23 system clear and obvious, and the function and flow direction of each part are clear at a glance. The three-way pipe 234, as a stable flow distribution structure, stably distributes the water vapor in the main humidification pipe 233 to the first humidification pipe 231 and the second humidification pipe 232, providing two clear and fixed flow distribution channels for water vapor. No additional switching device or complex control logic is required, which greatly improves the water vapor delivery efficiency, ensures the stability of water vapor delivery on different paths, and avoids problems such as water vapor leakage or uneven flow distribution caused by unstable connection or unreasonable structure.

[0116] Meanwhile, the three-way pipe 234 can accurately distribute the water vapor from the humidification main pipe 233 to the first humidification pipe 231 and the second humidification pipe 232 according to the design requirements, ensuring that the amount of water vapor leading to the visualization housing 21 and the humidification outlet 12 meets the predetermined ratio, thereby meeting the different needs of users for observing water vapor and humidifying the air, and improving the functionality and practicality of the humidification system.

[0117] Furthermore, the three pipe fittings of the T-connector 234 are tightly connected to the corresponding pipes, forming a relatively closed and stable connection structure. This better ensures the sealing of the connection points, effectively reducing the possibility of water vapor leakage and improving the reliability and stability of the humidification system. While distributing the flow, the T-connector 234 also plays a role in equalizing pressure. The standardized structure of the T-connector 234 makes the installation of the humidification pipe 23 more convenient and quick during the assembly of the indoor air conditioning unit 100. During maintenance and repair, the T-connector 234, as an independent component, is easy for maintenance personnel to inspect and replace.

[0118] In other embodiments, the entire humidification pipe 23 can also be integrally formed, and the angle between the humidification main pipe 233 and the first humidification pipe 231 and the second humidification pipe 232 can be reasonably set according to the internal space and structure of the air conditioner indoor unit 100.

[0119] In some embodiments, please refer to Figure 6 The diameter D1 of the first humidifying pipe 231 is smaller than the diameter D2 of the second humidifying pipe 232.

[0120] Thus, the diameter D1 of the first humidifying pipe 231 is smaller than the diameter D2 of the second humidifying pipe 232. The smaller diameter of the first humidifying pipe 231 results in a relatively narrow internal channel, which limits the amount of water vapor passing through. This is suitable for guiding a suitable amount of water vapor to the visual housing 21, allowing the user to easily observe the water vapor state without the need for a large amount of water vapor to accumulate there. The larger diameter of the second humidifying pipe 232 provides a wider channel, meeting the requirement of delivering a large amount of water vapor to the humidification outlet 12 to effectively humidify the indoor air.

[0121] In this way, the smaller diameter of the first humidifying pipe 231 ensures a moderate amount of water vapor entering the visualization housing 21, preventing excessive water vapor from blurring the view or forming large amounts of condensation that would affect observation. Users can clearly see the shape and flow of water vapor within the visualization housing 21, gaining a better understanding of the humidification system's operating status. The larger diameter of the second humidifying pipe 232 allows water vapor to pass through more smoothly and quickly, and a large amount of water vapor can be discharged from the humidification outlet 12 in a timely manner, improving humidification efficiency and enabling the indoor air to reach a suitable humidity level in a shorter time, meeting the user's needs for indoor humidification.

[0122] Furthermore, by limiting the diameter of the first humidification pipe 231, unnecessary large amounts of water vapor are prevented from entering the visualization housing 21, reducing water vapor waste. This allows the water vapor generating device 24 to more efficiently concentrate energy on generating water vapor that is delivered to the humidification outlet 12, improving energy utilization efficiency and reducing energy consumption. The first humidification pipe 231 has a small diameter, resulting in a relatively fast flow velocity and relatively low pressure when water vapor passes through it. The second humidification pipe 232 has a large diameter, resulting in a relatively slow flow velocity and relatively high pressure when water vapor passes through it. This pressure difference helps maintain the pressure balance within the entire humidification pipe system 23, ensuring that water vapor flows stably along the designed path and avoiding problems such as water vapor backflow or leakage caused by abnormal pressure.

[0123] In some embodiments, please refer to Figure 6 The diameter D1 of the first humidifying pipe 231 and the diameter D2 of the second humidifying pipe 232 are 10-30 mm.

[0124] Thus, the diameter D1 of the first humidifying pipe 231 and the diameter D2 of the second humidifying pipe 232 are both within the range of 10-30 mm, neither too large nor too small, ensuring the water vapor delivery function while adapting to the spatial layout of the indoor unit 100. For the first humidifying pipe 231, when the space of the viewing housing 21 is small, a smaller pipe diameter, such as around 10 mm, can be used to precisely control the amount of water vapor entering the viewing housing 21, facilitating observation. When the space of the viewing housing 21 is large, a maximum pipe diameter of 30 mm or 20 mm can also be used, ensuring a certain amount of water vapor is available for observation, preventing water vapor from being unable to reach the viewing housing or resulting in poor observation effects due to an excessively small pipe diameter. For the second humidifying pipe 232, a pipe diameter of 10-30 mm can provide a suitable water vapor flow rate under different humidification needs, meeting the basic requirements for indoor humidification.

[0125] Meanwhile, within this pipe diameter range, selecting suitable pipe materials is relatively easy, ensuring the strength and sealing of the pipeline. Generally, common plastic or metal pipes at this diameter have good pressure resistance and corrosion resistance, can withstand the pressure and humidity of water vapor, and are not prone to deformation, cracking, or leakage, ensuring the normal operation of the humidification system. It also has good compatibility with other components of the air conditioner indoor unit 100, such as the water vapor generating device 24 in the air humidification module 20 and the humidification outlet 12 on the casing 10, allowing for easy connection and assembly. The pipe diameter will not cause difficulties in connecting with other components or affect the overall structural compactness due to being too large or too small.

[0126] Furthermore, within a pipe diameter range of 10–30 mm, the humidifying pipe 23 ensures a stable output of water vapor. The pipe diameter is neither too small, which could lead to water vapor blockage or unstable flow, nor too large, which could cause excessive fluctuations in water vapor pressure. This helps maintain the stability of the humidification function of the indoor unit 100, ensuring that indoor humidity remains at a relatively stable level and providing users with a comfortable indoor environment.

[0127] In some embodiments, please refer to Figures 8 to 13 A decorative cavity 14 is formed in the part of the housing 10 corresponding to the transparent area 131. The decorative cavity 14 includes a front side and the front side of the decorative cavity 14 is transparent.

[0128] In some embodiments, please refer to Figure 11 The decorative cavity 14 includes a rear side panel 141, which corresponds to the transparent area 131 along the front-rear direction of the air conditioner indoor unit 100. The rear side panel 141 is provided with a through hole 142, and the transparent part of the visualization housing 21 is disposed in the through hole 142 so that the water vapor located in the visualization housing 21 can be observed through the transparent area 131 and the decorative cavity 14.

[0129] In some embodiments, please refer to Figures 10-12 The visualization housing 21 includes a front sidewall 212, which constitutes the transparent part of the visualization housing 21. The front sidewall 212 of the visualization housing 21 is disposed in the through hole 142 of the rear side plate 141.

[0130] Thus, a decorative cavity 14 is provided inside the housing 10. The front side of the decorative cavity 14 is transparent, forming a continuous transparent observation area together with the transparent part of the visualization housing 21. The rear side panel 141 is located at the rear of the decorative cavity 14, corresponding to the transparent area 131 of the air conditioner indoor unit 100 in the front-back direction. The front side wall 212 of the visualization housing 21 is located in the through hole 142 of the rear side panel 141, realizing the connection between the visualization housing 21 and the decorative cavity 14. The function of observing water vapor is combined with the decorative function, realizing multiple functions within the limited space of the housing 10, without occupying too much space, and providing users with a unique visual experience.

[0131] Furthermore, the decorative cavity 14 serves not only for observing water vapor but also, through its internal decorative design—such as the arrangement of soft lighting, exquisite patterns, or shapes—to create a unique visual effect for the air conditioner indoor unit 100. When water vapor flows within the visual housing 21, it interacts with the decorative elements of the decorative cavity 14 to form a unique visual effect. This design, combining visualization and decorative functions, allows the product to stand out, thereby increasing its market competitiveness.

[0132] It should be explained that the front side of the decorative cavity 14 can be semi-transparent or fully transparent, as long as it does not affect the observation effect of water vapor on the visible housing 21. The front side of the decorative cavity 14 can be provided with a transparent glass or other front panel, or the front side of the decorative cavity 14 can be formed directly by enclosing it with the housing 10 without any structure.

[0133] At the same time, the combination of the transparent front side of the decorative cavity 14 and the transparent part of the visualization shell 21 forms a transparent observation channel from front to back. The situation inside the visualization shell 21 and the decorative cavity 14 can be directly observed from the transparent area 131 in front. The flow of water vapor and other states can be clearly seen. The various parts work together to achieve a unique visualization function.

[0134] Moreover, the through hole 142 provides a precise mounting position for the front sidewall 212 of the visualization housing 21. The through hole 142 on the rear side plate 141 allows the front sidewall 212 of the visualization housing 21 to be more tightly integrated with the decorative cavity 14. During the installation process, the visualization housing 21 and the decorative cavity 14 can be assembled quickly and accurately, ensuring that the relative positions of the two are accurate, reducing the adjustment and calibration time during the installation process, and improving the efficiency of production assembly.

[0135] Meanwhile, the front sidewall 212 of the visualization housing 21 is located within the through hole 142, which is equivalent to adding a support point to the rear side plate 141 of the decorative cavity 14. This helps to enhance the connection strength between the decorative cavity 14 and the visualization housing 21, making the entire structure more stable under external forces and less prone to deformation or damage, thus improving the product's durability. When maintenance is required on the visualization housing 21 or the decorative cavity 14, this structure facilitates disassembly and reinstallation. Since the front sidewall 212 is located within the through hole 142, the visualization housing 21 can be easily separated from the decorative cavity 14 during disassembly, making it easier for maintenance personnel to inspect, repair, or replace various components, reducing the difficulty and cost of maintenance.

[0136] In some embodiments, please refer to Figures 14 to 18 The air humidification module 20 also includes a light-emitting element 22, which is located on the side of the visualization housing 21 away from the decorative cavity 14.

[0137] Thus, the light-emitting element 22 is positioned on the side of the visualization housing 21 away from the decorative cavity 14. The light emitted by it can directly act on the visualization housing 21 and the water vapor inside it. The light emitted by the light-emitting element 22 can pass through the visualization housing 21 and illuminate the water vapor inside, making the water vapor more clearly visible under the light. Furthermore, the light may also pass through the transparent part of the visualization housing 21 and the connection point between it and the decorative cavity 14, creating a certain light and shadow effect inside the decorative cavity 14, and together with the overall structure, creating a unique visual atmosphere.

[0138] In this way, the light emitted by the light-emitting element 22 can illuminate the water vapor inside the visualization shell 21 from the side or back. Through the scattering and refraction of light, the shape of the water vapor is more clearly displayed. For example, the flow direction and concentration distribution of the water vapor can be seen more clearly, allowing users to observe the humidification process more intuitively, which increases the fun and technological feel of the product.

[0139] In addition, the light-emitting element 22 is positioned on the side of the visualization housing 21 away from the decorative cavity 14, so that it is kept at a certain distance from the decorative cavity 14 and the interior of the visualization housing 21, which may contain a lot of moisture. This reduces the direct impact of moisture on the light-emitting element 22, lowers the risk of damage to the light-emitting element 22 due to moisture or water accumulation, extends the service life of the light-emitting element 22, and improves the stability and reliability of the entire air humidification module 20.

[0140] Specifically, in some embodiments, please refer to Figure 9 The rear panel 141 includes a light-transmitting area 1411, which extends along the length of the indoor air conditioning unit 100.

[0141] In some embodiments, please refer to Figures 17 to 18The light-emitting element 22 includes a light strip body 221, which extends along the length of the air conditioner indoor unit 100 and corresponds to the light-transmitting area 1411 along the front-back direction of the air conditioner indoor unit 100.

[0142] In some embodiments, please refer to Figure 18 The light-emitting element 22 also includes a light strip extension 222, which is connected to the light strip body 221. The light strip extension 222 extends along the height direction of the air conditioner indoor unit 100 and corresponds to the visual housing 21 along the front-back direction of the air conditioner indoor unit 100.

[0143] Thus, the light strip body 221 extends along its length and corresponds to the light-transmitting area 1411, providing relatively uniform basic lighting for the interior of the decorative cavity 14, thereby showcasing the decorative environment inside the cavity. Meanwhile, the light strip extension 222 illuminates the visualization housing 21, allowing the water vapor inside to be clearly illuminated. The combination of these two elements ensures that the decorative cavity 14 has sufficient brightness while highlighting the observation area of ​​the visualization housing 21, enabling users to more clearly observe the generation and flow of water vapor, thus enhancing the visualization effect.

[0144] Because the light strip extends in both length and height, it makes full use of the internal space of the air conditioner indoor unit 100. The light strip body 221 is arranged along the length direction and cooperates with the light-transmitting area 1411 of the rear panel 141 to achieve large-area illumination without occupying too much extra space. The light strip extension 222 extends along the height direction to illuminate the visible housing 21, making the layout of various components more compact and reasonable, and improving space utilization. It provides convenience for users to observe the inside of the housing 10 from different angles, improving the comprehensiveness and flexibility of observation.

[0145] In some embodiments, please refer to Figure 4 The water vapor generating device 24 can be an evaporative humidifier or an ultrasonic humidifier.

[0146] Evaporative humidifiers convert water into water vapor through natural evaporation, releasing the vapor slowly and evenly into the air. This results in a more natural humidification effect, stabilizing air humidity and preventing sudden spikes in localized humidity levels. It helps maintain indoor humidity levels closer to those found in the natural environment, reducing indoor environmental problems caused by over-humidification or uneven humidification. Generally, they operate with low noise levels; the fan noise is usually within an acceptable range and will not significantly disturb users' lives or rest, making them suitable for bedrooms, studies, and other places where noise levels are high. They do not release minerals or other impurities from the water into the air with the vapor, and they do not form white powdery substances on furniture, floors, or other surfaces, keeping the indoor environment clean.

[0147] Ultrasonic humidifiers convert electrical energy into high-frequency mechanical vibrations using ultrasonic transducers. These vibrations break water into tiny droplets, forming a mist. They can rapidly convert large amounts of water into mist, quickly increasing air humidity. They are highly efficient, producing extremely fine mist particles, typically at the micrometer level, which disperse more evenly in the air and mix thoroughly, resulting in a more significant humidification effect. The atomization rate can be easily adjusted via a control circuit, allowing users to flexibly adjust the humidification intensity according to their needs and indoor environment.

[0148] In other embodiments, the water vapor generating device 24 may also be a hot evaporation humidifier, a cold mist humidifier electrode type, a humidifier, or a wet film humidifier.

[0149] In some embodiments, the air conditioner indoor unit 100 further includes a second fan (not shown in the figure), which is disposed inside the housing 10, and the airflow of the second fan can send water vapor out through the humidification outlet 12.

[0150] Thus, the second fan drives the impeller to rotate via a motor. During rotation, the impeller generates centrifugal force or axial thrust, causing airflow. The second fan in this application operates at the fresh air outlet and humidification outlet 12. On one hand, it continuously introduces fresh outdoor air into the room, diluting indoor polluted air, such as harmful gases like carbon dioxide, formaldehyde, and benzene, as well as exhaled waste gases, keeping the indoor air fresh and providing a healthier breathing environment. On the other hand, it works in conjunction with the ventilation ducts and exhaust vents of the air conditioning system to expel polluted indoor air outdoors, achieving indoor air circulation and maintaining indoor air cleanliness and quality.

[0151] Meanwhile, the fresh air outlet duct of the second fan introduces airflow into the humidification outlet 12, which evenly distributes the water vapor from the humidification outlet 12 into the room. The humidification vapor airflow utilizes the airflow channels and power unit of the fresh air system, eliminating the need for a separate, complex air supply system for the humidification function, thus reducing energy consumption and operating costs. Furthermore, proper humidity control helps improve the energy efficiency of the air conditioning system, because at suitable humidity levels, the human body perceives temperature more comfortably. The air conditioning system can achieve the same level of comfort with relatively low energy consumption, thus realizing energy savings.

[0152] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
