Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a wall-mounted air conditioner indoor unit. Background Technology

[0002] A typical wall-mounted air conditioner indoor unit includes a casing and a heat exchange module and a fresh air module housed within the casing. The heat exchange module includes an indoor heat exchanger and a heat exchange fan. The indoor heat exchanger exchanges heat with the airflow inside the casing. The heat exchange fan drives indoor air into the casing through the air inlet at the top, where it exchanges heat with the indoor heat exchanger before exiting through the air outlet at the bottom front of the casing. The fresh air module introduces fresh outdoor air to improve indoor air quality.

[0003] Wall-mounted air conditioners cause a decrease in indoor humidity during cooling and heating. When cooling, water vapor in the air condenses into water and is expelled outdoors; when heating, the indoor temperature rises, lowering the relative humidity. Humans have certain comfort requirements regarding indoor humidity, and prolonged exposure to low humidity environments can cause discomfort. Therefore, to achieve humidification, some wall-mounted air conditioner indoor units include an internal steam humidification device. This device typically includes key components such as a water tank, heating element, and a stirring element. The water tank stores the humidification water, the heating element heats the water to form steam, and the stirring element agitates the water flow to accelerate steam generation.

[0004] Most common agitators currently use a motor to directly drive the agitator impeller. This structure has many drawbacks. On the one hand, the agitator impeller is located inside the water tank, and the motor passes through the water tank and connects to the agitator impeller. The mechanical transmission structure between the two is relatively complex, the installation process is cumbersome, and the space requirements are high, limiting the flexibility of the motor's layout within the air conditioner's indoor unit. On the other hand, the motor is directly exposed to the water environment, requiring additional sealing structures and posing certain safety hazards. For example, water vapor may seep into the motor, causing a short circuit and damage, affecting the agitator's lifespan and reliability. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,

[0006] This utility model provides a wall-mounted air conditioner indoor unit, which includes:

[0007] The casing has a first inner cavity and a second inner cavity arranged along its own length. An air conditioning air inlet is provided on the top of the casing, and an air conditioning air outlet is provided on the bottom front side of the casing.

[0071] The wall-mounted air conditioner indoor unit 100 provided in this embodiment of the utility model can have multiple implementation forms. Among them, Figures 1-15 This is an illustrative embodiment of the wall-mounted air conditioner of this utility model. Wherein, Figure 1 This is an external view of a wall-mounted air conditioner indoor unit 100, which is part of an air conditioner. The wall-mounted air conditioner indoor unit 100 is installed indoors and used for heat exchange with the indoor environment.

[0072] In addition, air conditioners also include outdoor units, which are usually located outdoors and are used to carry indoor heat to the outside.

[0073] refer to Figure 1 In one illustrative embodiment of the wall-mounted air conditioner indoor unit 100 provided by this utility model, the wall-mounted air conditioner indoor unit 100 may include a housing 1. The housing 1 is installed indoors, and the housing 1 forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0074] The housing 1 is roughly rectangular in shape, with the left and right ends of the housing 1 being opposite each other along its length.

[0075] The housing 1 has a top end and a bottom end, which are opposite ends of the housing 1 in the height direction. The front side and the rear side of the housing 1 are opposite sides in the thickness direction.

[0076] The housing 1 is located at the top of the room or in the upper space of the room. The front of the housing 1 faces the user and the rear of the housing 1 faces the wall, making it suitable for connection with the wall.

[0077] The casing 1 has an internal accommodating space. This space is used to house and fix various components in the wall-mounted air conditioner indoor unit 100, which can prevent external objects from colliding with the various components inside the casing 1, thereby improving the reliability of the wall-mounted air conditioner indoor unit 100 during transportation or installation.

[0078] In some embodiments of this application, reference is made to Figure 1 The housing 1 may include an air conditioning inlet 11.

[0079] The air conditioning inlet 11 is connected to the housing space. As the inlet for external air to flow into the casing 1, the air conditioning inlet 11 allows indoor air to enter the housing space through the air conditioning inlet 11.

[0080] In some embodiments of this application, reference is made to Figure 2 The housing 1 may include an air conditioning vent 12.

[0081] The air conditioner outlet 12 is connected to the housing space. The air conditioner outlet 12 serves as the outlet 103 for the heat exchange airflow to flow out of the housing 1, allowing the airflow in the housing space to flow out to the indoor environment through the air conditioner outlet 12.

[0082] The air inlet 11 can be located at the top of the housing 1. The air outlet 12 can be located on the front side of the housing 1 and near the bottom of the housing 1, that is, the air outlet 12 is located at the bottom front side of the housing 1. In this embodiment, when the indoor unit of the air conditioner is working, the indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0083] The air conditioner outlet 12 is elongated and can be extended along the length of the casing 1, which improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0084] In some embodiments of this application, reference is made to Figure 2 The indoor unit 100 of the wall-mounted air conditioner may include an indoor heat exchanger 2.

[0085] The indoor heat exchanger 2 extends along the length of the casing 1 and is located in the housing space inside the casing 1 for heat exchange with the airflow inside the casing 1.

[0086] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include a heat exchange fan 3.

[0087] The heat exchange fan 3 is installed in the housing 1 and is used to drive the indoor air outside the housing 1 into the housing 1 through the air inlet. The heat exchange fan 3 drives the air in the housing to flow along the air inlet 11 toward the air outlet 12.

[0088] The heat exchange fan 3 can be a cross-flow fan, located below the indoor heat exchanger 2. To improve heat exchange efficiency, the indoor heat exchanger 2 is partially enclosed by the heat exchange fan 3, effectively increasing the heat exchange area.

[0089] Continue to refer to Figure 2 The heat exchange fan 3 is positioned near the air conditioner outlet 12, while the indoor heat exchanger 2 is positioned near the air conditioner inlet 11 relative to the heat exchange fan 3. In other words, in the airflow direction within the casing 1, the heat exchange fan 3 is located downstream of the indoor heat exchanger 2.

[0090] When the indoor unit 100 of the wall-mounted air conditioner is running, driven by the heat exchange fan 3, indoor air enters the containment space through the air conditioner inlet 11. The indoor air in the containment space flows through the indoor heat exchanger 2 for heat exchange. The heat exchanged airflow is discharged to the outside through the air conditioner outlet 12, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0091] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include an air guide plate 13.

[0092] The air guide plate 13 is rotatably connected to the housing 1 and is located at the air conditioning outlet 12. The air guide plate 13 opens or closes the air conditioning outlet 12. When the air guide plate 13 opens the air conditioning outlet 12, it is used to guide the heat exchange airflow.

[0093] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include an air inlet grille 14.

[0094] The air intake grille 14 is located at the air conditioning intake 11 to prevent larger impurities from entering the containment space.

[0095] In some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include an air inlet filter, which is disposed between the air inlet grille 14 and the indoor heat exchanger 2 to filter indoor air and improve air quality.

[0096] refer to Figure 3 In some embodiments of this application, the housing 1 may include a base 11. The base 11 forms the rear side of the indoor air conditioning unit 100 and is adapted to be mounted on a wall.

[0097] refer to Figure 2The housing 1 may include a cover 192. The cover 192 is mounted on the base 11, and a heat exchange air duct is formed between the cover 192 and the base 11.

[0098] The cover 192 is roughly in the shape of a cuboid frame. The rear side of the cover 192 is open, and the cover 192 covers the front side of the base 11 and is connected to the base 11 to form the housing 1.

[0099] The air conditioning inlet 11 and air conditioning outlet 12 are both located on the cover 192. The indoor heat exchanger 2 and the heat exchange fan are both mounted on the base 11.

[0100] The housing may include a front panel 15. The front panel 15 is located on one side of the cover 192 and is detachably connected to the cover 192. By detachably connecting the front panel 15 to the cover 192, the front panel can be removed to inspect the interior of the housing 1 when the indoor unit of the air conditioner malfunctions.

[0101] An outdoor unit for an air conditioner may include an outdoor unit housing. The outdoor unit housing may contain an installation cavity.

[0102] The outdoor unit housing may include an outdoor air inlet. The outdoor air inlet may communicate with the mounting cavity. The outdoor air inlet can be used to introduce outdoor air into the mounting cavity.

[0103] The outdoor unit housing may include an outdoor air outlet. The outdoor air outlet may communicate with the mounting cavity. The outdoor air outlet can be used to exhaust air from inside the mounting cavity to the outside of the mounting cavity.

[0104] An outdoor unit for an air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be located inside an installation cavity.

[0105] An outdoor unit for an air conditioner may include an outdoor fan. The outdoor fan may be installed inside the mounting cavity.

[0106] The rotation of the outdoor fan causes outdoor air to enter the installation cavity through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the installation cavity through the outdoor air outlet.

[0107] An air conditioner may include a compressor. The compressor is located within the mounting cavity.

[0108] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device may be provided in the indoor unit 100 or the outdoor unit of a wall-mounted air conditioner.

[0109] An air conditioner performs a refrigeration cycle by using a compressor, condenser, throttling device, and indoor heat exchanger 2. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0110] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0111] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0112] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0113] The indoor heat exchanger 2 evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low temperature and low pressure state, to the compressor.

[0114] Indoor heat exchanger 2 achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner can regulate the temperature of the indoor space.

[0115] Of the two heat exchangers, indoor heat exchanger 2 and outdoor heat exchanger 2, one is a condenser and the other is indoor heat exchanger 2. When indoor heat exchanger 2 is used as a condenser, the air conditioner is used as a heater in heating mode. When indoor heat exchanger 2 is used as an indoor heat exchanger 2, the air conditioner is used as a cooler in cooling mode.

[0116] In some embodiments of this application, the interior of the housing 1 defines a first inner cavity 16. The heat exchange fan 3 and the indoor heat exchanger 2 are disposed in the first inner cavity 16.

[0117] The first inner cavity 16 provides installation space for the heat exchange fan 3 and the indoor heat exchanger 2, which helps to ensure good coordination between the heat exchange fan 3 and the indoor heat exchanger 2 and improve heat exchange efficiency.

[0118] In some embodiments of this application, to achieve the fresh air function, the wall-mounted air conditioner indoor unit 100 may include a fresh air module 4. The fresh air module 4 is used to introduce outdoor fresh air into the indoor environment.

[0119] refer to Figure 3 The housing 1 has a second inner cavity 17 inside, and the fresh air module 4 is located in the second inner cavity 17.

[0120] The second inner cavity 17 provides a relatively independent installation space for the fresh air module 4, ensuring the relative independence of the fresh air module 4 from other components, avoiding mutual interference, and contributing to the integration and functionality of the wall-mounted air conditioner indoor unit 100.

[0121] Continue to refer to Figure 3The first inner cavity 16 and the second inner cavity 17 are arranged along the length of the casing 1. This arrangement allows the heat exchange module formed by the fresh air module 4, the heat exchange fan 3, and the indoor heat exchanger 2 to be arranged in an orderly manner along the length of the casing 1, which facilitates the separate installation, maintenance, and management of each module, and also makes the internal structure of the casing 1 more compact and reasonable.

[0122] refer to Figure 4 , Figure 5 The fresh air module 4 may include a fresh air volute 41, which forms the appearance of the fresh air module 4.

[0123] The fresh air volute 41 may include a fresh air inlet, which is suitable for connecting with the external environment.

[0124] The fresh air inlet can be connected to the external environment through a fresh air duct.

[0125] The fresh air volute 41 may include a fresh air outlet 43, which is located on the fresh air volute 41 and is used to output outdoor fresh air to provide fresh air to the room, improve indoor air quality, and benefit the user's health and comfort.

[0126] The fresh air outlet 43 is connected to the fresh air inlet to form a fresh air duct. The fresh air duct can effectively guide the outdoor fresh air to enter from the fresh air inlet and flow along a predetermined path, ensuring the smoothness and continuity of the fresh air delivery process.

[0127] The housing 1 may include an air conditioning fresh air inlet 15. The air conditioning fresh air inlet 15 is connected to the fresh air outlet 43 so that the outdoor fresh air output from the fresh air outlet 43 can flow into the indoor environment through the air conditioning fresh air inlet 15.

[0128] The fresh air module 4 may include a fresh air fan 42, which is located in the fresh air duct inside the fresh air volute 41. Through the operation of the fresh air fan 42, outdoor fresh air is introduced into the fresh air duct through the fresh air inlet, and then output through the fresh air outlet 43, and finally flows into the room through the air conditioning fresh air outlet 15.

[0129] Among them, the fresh air fan 42 can be a centrifugal fan. Centrifugal fans have high wind pressure and stable airflow output characteristics, which can generate sufficient pressure in fresh air ducts and fresh air channels to overcome airflow resistance and ensure that fresh air can be smoothly delivered from the outside to the inside. At the same time, the structural characteristics of centrifugal fans enable them to provide uniform and stable airflow, improving the quality and effect of fresh air delivery.

[0130] In some embodiments of this application, the fresh air volute 41 is connected to the housing 1. The fresh air volute 41 can be connected to the housing 1 by fasteners such as screws or bolts. In order to prevent the vibration generated by the rotation of the fresh air fan 42 from being transmitted to the housing 1 and other components, shock-absorbing rubber is provided between the fastener and the housing 1 to buffer and absorb vibration.

[0131] In some embodiments of this application, reference is made to Figure 10 The indoor unit 100 of the wall-mounted air conditioner may include a drive unit.

[0132] The drive unit is installed inside the housing 1 and is connected to the end of the heat exchange fan 3 away from the fresh air fan 42, for driving the heat exchange fan 3 to operate. The drive unit may include a drive motor.

[0133] In some embodiments of this application, the fresh air fan 42 and the heat exchange fan 3 are arranged coaxially, and the fresh air fan 42 and the heat exchange fan 3 extend along the length direction of the housing 1.

[0134] like Figure 6 As shown, the fresh air fan 42 is connected to a connecting shaft, and the fresh air fan 42 is connected to the heat exchange fan 3 through the connecting shaft so that the fresh air fan 42 and the heat exchange fan 3 operate synchronously.

[0135] It should be noted that the connecting shaft extends along the length of the housing 1.

[0136] When an air conditioner cools or heats an indoor environment, it causes the humidity to drop. People indoors may feel uncomfortable due to the continuously decreasing humidity, which affects the user experience.

[0137] In order to solve the above-mentioned technical problems, in some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include a steam humidification device for providing hot and humid steam.

[0138] In this embodiment, by setting up a steam humidification device, the humidity of indoor air can be effectively increased, improving the comfort of the indoor environment. Especially in dry seasons or regions, it provides users with a more comfortable and healthy indoor air environment, enhancing the user experience.

[0139] The steam humidification device is located in the second inner cavity 17. Specifically, the steam humidification device is located on the side of the fresh air module 4 away from the heat exchange fan 3.

[0140] In this embodiment, the steam humidification device is integrated into the fresh air module 4 of the wall-mounted air conditioner indoor unit 100. This configuration allows the humidification function to be closely integrated with the fresh air function of the air conditioner, which not only optimizes the internal space layout of the air conditioner indoor unit and improves space utilization, but also enables wide-area humidification of the indoor space.

[0141] Specifically, such as Figure 6 As shown, the steam humidification device may include a water tank 6. The water tank 6 defines a water storage chamber 61 for storing water.

[0142] By setting up water tank 6, the water can be stored stably, which facilitates subsequent treatments such as heating the water. At the same time, it provides sufficient water reserves for the normal operation of the steam humidification device, ensuring the continuity and stability of the humidification effect.

[0143] The steam humidification device may include a heating plate 7, which is used to heat the water in the water storage tank 61 and generate water vapor.

[0144] The top of the water tank 6 is provided with an air outlet 62, which is used to output hot and humid steam.

[0145] The air outlet 62 is connected to the fresh air outlet 43, so that the water vapor generated in the water tank 6 can smoothly enter the fresh air outlet 43 through the air outlet 62, and then be transported to the indoor environment with the fresh air. This realizes the organic combination of humidification and fresh air functions, which can ensure that the water vapor is evenly distributed in the indoor air and improve the uniformity and effectiveness of humidification.

[0146] With the help of the fresh air fan 42, hot and humid steam can be quickly blown into the room, improving humidification efficiency. The combination of hot and humid steam and fresh air can, on the one hand, compensate for the temperature of the fresh air, and on the other hand, allow water vapor to travel a longer distance and cover a wider range, thus achieving wide-area humidification of the indoor space.

[0147] The steam humidification device may include a magnetic stirrer 8. The magnetic stirrer 8 can stir the water in the water storage tank 61, so that the water is heated more evenly during the heating process, avoiding problems such as poor humidification effect caused by local overheating or uneven heating.

[0148] At the same time, the stirring action helps to improve the evaporation efficiency of water, accelerate the generation of water vapor, further enhance the humidification efficiency and effect, and ensure that the indoor air humidity can quickly reach the expected level.

[0149] Specifically, the magnetic stirrer 8 may include a magnetic rotor 81, which is located inside the water storage tank 61.

[0150] The rotation of the magnetic rotor 81 agitates the water in the water storage tank 61. The rotational disturbance of the water flow causes the hot and humid steam in the water storage tank 61 to diffuse freely, so that the steam is continuously drawn away by the fresh air flow and sent into the indoor space.

[0151] The steam humidification device may include a mounting section 64, which is disposed within a water storage tank 61. A magnetic rotor 81 is housed within the mounting section 64.

[0152] The mounting section 64 provides mounting space for the magnetic rotor 81. For example... Figure 8 , Figure 9 As shown, the mounting part 64 is connected to the water storage tank 61, and the magnetic rotor 81 can rotate relative to the mounting part 64.

[0153] The mounting part 64 is connected to the water storage tank 61, ensuring that the mounting part 64 where the magnetic rotor 81 is located can fully contact the water in the water storage tank 61, so that the stirring effect can be effectively transferred to the water in the water storage tank 61, further improving the comprehensiveness and uniformity of the stirring effect, thereby better promoting the heating and evaporation process of water.

[0154] The magnetic stirrer 8 may include a rotor drive base 82, which is mounted on the housing 1.

[0155] The rotor drive base 82, as the drive part of the magnetic stirrer 8, is installed on the housing 1 to provide stable support and fixation, ensuring stable operation during the process. At the same time, it is easy to work in conjunction with other components inside the housing 1 to form a complete drive system, providing power support for the rotation of the magnetic rotor 81 and ensuring the normal realization of the stirring function.

[0156] The rotor drive base 82 is correspondingly arranged with the magnetic rotor 81. The rotor drive base 82 is used to generate a magnetic field after being energized. This magnetic field drives the magnetic rotor 81 to rotate in the mounting part 64 to stir the water in the water storage tank 61.

[0157] In this embodiment, a magnetic stirrer 8 is used to stir the water in the water storage tank 61. The magnetic stirrer 8 uses a magnetic field for long-distance non-contact transmission, which eliminates the need for a complex mechanical transmission structure, simplifies the overall structure, facilitates installation and maintenance, reduces production costs and maintenance difficulty, and makes the installation position flexible, without being strictly limited by the space and position of the mechanical transmission structure.

[0158] It should be noted that the rotor drive base 82 may include a permanent magnet and a motor that drives the permanent magnet to rotate. After the rotor drive base 82 is powered on, the permanent magnet rotates under the drive of the motor, thereby generating a rotating magnetic field. The rotating magnetic field will couple and drive the magnetic rotor 81 in the water storage tank 61 to rotate synchronously.

[0159] In this embodiment, the magnetic rotor 81 is driven to rotate by the long-distance non-contact transmission of the magnetic field, thereby agitating the water inside the water storage tank 61 and accelerating the convective heat transfer of the water. This not only shortens the time for generating hot and humid steam, but the rotational disturbance of the water flow also promotes the free diffusion of hot and humid steam in the water storage tank 61, so that the steam is continuously drawn away by the fresh air flow and sent into the indoor space.

[0160] In some embodiments of this application, such as Figure 7As shown, the heating plate 7 is mounted on the housing 1.

[0161] The heating plate 7 is located outside the water storage tank 61 and abuts against the bottom wall of the water tank 6.

[0162] In this embodiment, the heating plate 7 is installed on the housing 1 to heat the bottom wall of the water tank 6. This can effectively heat the water in the water storage tank 61 without affecting the overall structure of the water tank 6. At the same time, it is also convenient to install and maintain the heating plate 7, thereby improving the heating efficiency and the reliability of the device.

[0163] Furthermore, the heating plate 7 is located outside the water storage tank 61, which can effectively avoid potential safety hazards caused by the heating plate 7 coming into direct contact with water, extend the service life and heating efficiency of the heating plate 7, and ensure the stable operation of the steam humidification device.

[0164] In some embodiments of this application, the steam humidification device may include a housing 9, which is connected to the fresh air module 4.

[0165] The housing 9 is connected to the fresh air module 4, which improves the integration of the steam humidification device and the fresh air module 4 and optimizes the overall structural layout.

[0166] like Figure 14 As shown, the housing 9 has a receiving portion 95 defined inside, and the side of the housing 9 has a first opening 91 that communicates with the receiving portion 95. The water tank 6 is pulled out and disposed in the receiving portion 95 through the first opening 91.

[0167] The water tank 6 is removably installed in the receiving section 95, which greatly improves the ease of installation and disassembly of the water tank 6, making it convenient for users to clean and maintain the water tank 6, and also makes it easy to add water to the water tank 6, thus improving the user experience.

[0168] The first opening 91 is located on the front side of the housing 9, allowing the user to pull out and install the water tank 6 from the front side of the housing 9, which is convenient for the user.

[0169] Furthermore, a mounting port is provided on the front side of the cover 192, which corresponds to the first opening 91. The water tank 6 is installed in the receiving part 95 through the mounting port and the first opening 91 in sequence.

[0170] like Figure 5 As shown, in this embodiment, the housing 9 and the fresh air volute 41 are integrally set, making the overall structure more compact.

[0171] In some embodiments of this application, the top of the housing 9 is provided with a through portion 92, which is connected to the receiving portion 95.

[0172] like Figure 8As shown, the top of the water tank 6 is open to form the above-mentioned air outlet 62. The air outlet 62 abuts against the top wall of the housing 9 so that the air outlet 62 is connected to the through part 92.

[0173] In this embodiment, by providing a through-hole 92 at the top of the housing 9 and connecting the air outlet 62 of the water tank 6 to the through-hole 92, it is ensured that the hot and humid steam can be stably and smoothly discharged from the water tank 6 and the housing 9, avoiding steam leakage and improving the efficiency of steam humidification.

[0174] In some embodiments of this application, the through section 92 is connected to the fresh air outlet 43 via the guide member 10. The guide member 10 guides the hot and humid steam from the through section 92 to the fresh air outlet 43, allowing the steam to be quickly transported into the indoor space under the influence of fresh air, thereby improving the efficiency of water vapor transport and ensuring the humidification effect.

[0175] Specifically, reference Figure 11 The guide member 10 has a guide channel 101 defined inside.

[0176] refer to Figure 8 , Figure 11 and Figure 15 The guide component 10 is provided with an inlet 102 and an outlet 103 connected to the guide channel 101. The inlet 102 is connected to the through section 92, and the outlet 103 is connected to the fresh air outlet 43, so that the hot and humid steam flowing out of the outlet 62 flows sequentially through the through section 92 and the guide channel 101 to the fresh air outlet 43. Figure 11 In the diagram, the red lines with solid arrows represent the flow paths of the hot, moist steam.

[0177] In some embodiments, the height of the inlet 102 is lower than the height of the outlet 103. The central axis of the flow channel 101 forms an angle with a plane perpendicular to the height direction of the housing 1.

[0178] In this embodiment, the height of the inlet 102 is set lower than the height of the outlet 103, and the guide channel 101 is tilted. By utilizing gravity, some of the humid and hot steam condensed inside the guide channel 101 can flow back to the water storage tank 61, reducing water waste. At the same time, the guide channel 101 is kept unobstructed to prevent condensate from accumulating and affecting the normal flow of steam, thus ensuring the long-term stable operation of the steam humidification device.

[0179] In some embodiments, the inlet 102 is provided on the bottom wall of one end of the flow channel 101, and the outlet 103 is provided at the other end of the flow channel 101. This arrangement makes the height of the inlet 102 lower than the height of the outlet 103.

[0180] By taking advantage of the natural upward trend of steam, the height of the inlet 102 of the guide channel 101 is set to be lower than the height of the outlet 103, thereby improving the steam delivery efficiency and humidification effect.

[0181] In some embodiments of this application, a heat insulation layer 94 is provided on the opposite sidewall of the housing 9, the heat insulation layer 94 is located in the receiving part 95, and the heat insulation layer 94 is in contact with the water tank 6.

[0182] In this embodiment, by setting the heat insulation layer 94, the heat radiated outward when heating water in the water storage tank 61 can be effectively isolated. On the one hand, it can ensure that the shell 9 containing the water storage tank 61 will not deform or age due to long-term high-temperature heating. On the other hand, it can also reduce the heat loss from the side wall of the shell 9, improve the heat utilization efficiency, and make the water temperature rise rapidly, thereby improving the efficiency of steam generation.

[0183] In some embodiments, the insulation layer 94 may be a silica aerogel insulation felt.

[0184] Silica aerogel insulation felt has excellent thermal insulation properties, which can more effectively reduce heat exchange, further reduce heat loss of water in water tank 6, and improve the stability of humidification effect.

[0185] Meanwhile, silica aerogel insulation felt is lightweight, easy to install and use, and will not significantly affect the overall structure and weight of the steam humidification device.

[0186] In some embodiments of this application, the shell 9 is provided with multiple support ribs 96, which are used to support the water tank 6 and prevent excessive heat from being transferred to the bottom wall of the shell 9.

[0187] In some embodiments of this application, a water pipe interface 93 is provided on the top of the first sidewall of the housing 9. The water pipe interface 93 is connected to an external water supply device or a condensate drain outlet via a water supply pipe. A water pump is provided in the water supply pipe.

[0188] In this embodiment, by setting up a water pipe interface 93 and a water supply pipe, automatic water supply or condensate recycling can be achieved, eliminating the need for frequent manual water addition and reducing the user's maintenance burden. The configuration of the water pump ensures a stable water supply, meeting the water demand of the water storage tank 61, especially when the water level is low, it can replenish the water source in time and ensure the continuous operation of the steam humidification device.

[0189] It should be noted that when the water level in the water storage tank 61 drops to a certain level, the water pump is activated, allowing external water sources to automatically replenish the water storage tank 61 through the water pipe interface 93. This ensures the continuous and stable operation of the steam humidification device, greatly improving its ease of use and intelligence. When the water level in the water storage tank 61 exceeds the preset level, the water pump stops supplying water.

[0190] like Figure 12 , Figure 15 As shown, the water tank 6 is provided with a through hole 63 through which a water supply pipe interface 93 passes. The water outlet end of the water pipe interface 93 extends through the through hole 63 into the water storage tank 61.

[0191] In this embodiment, the first sidewall is positioned opposite to the first opening 91. That is, the through hole 63 is located on the rear side of the water tank 6.

[0192] The water outlet of the water pipe interface 93 connects to the water storage compartment 61 from the rear of the water tank 6, optimizing the use of internal space. It also helps to conceal the water supply pipe, reducing its impact on the appearance of the indoor unit 100 of the wall-mounted air conditioner and improving overall aesthetics. Furthermore, the through hole 63 at the rear facilitates the connection of the water supply pipe to the water pump and external water supply devices.

[0193] It should be noted that after the water tank 6 is installed in the shell 9, the water outlet of the water pipe interface 93 on the shell 9 is aligned with the insertion through hole 63 to extend into the water storage tank 61, so as to achieve precise connection between the water supply pipe and the water tank 6, so that the water supply can flow directly into the water storage tank 61 and improve the water supply efficiency.

[0194] In some embodiments of this application, the bottom of the housing 1 is provided with a protrusion 18, and the bottom of the water tank 6 is formed with a connecting part 65 that is adapted to the protrusion 18.

[0195] In this embodiment, the bottom of the housing 9 is adapted to the protrusion 18, and the protrusion 18 abuts against the bottom of the housing 9. At the same time, the connecting part 65 of the water tank 6 abuts against the bottom of the housing 9, which enhances the connection stability between the water tank 6 and the housing 1 and improves the overall stability of the steam humidification device.

[0196] The rotor drive base 82 and the heating plate 7 are mounted in the protrusion 18. The protrusion 18 provides a solid support for the heating plate 7 and the rotor drive base 82, ensuring stable heating and rotation of the magnetic rotor 81.

[0197] like Figure 10 As shown, the heating plate 7 is located above the rotor drive base 82, so that the rotor drive base 82 and the heating plate 7 are integrated and space can be utilized more compactly. The heating plate 7 abuts against the connecting part 65 and is used to heat the connecting part 65, thereby heating the water in the water storage tank 61 and forming water vapor.

[0198] refer to Figure 7 In some embodiments, a pressure sensor 5 is provided on the protrusion 18 to abut against the connecting portion 65, and the pressure sensor 5 is located on one side of the heating plate 7.

[0199] Pressure sensor 5 is electrically connected to heating plate 7, and the control board is configured to turn on or off the power supply to heating plate 7 according to the pressure signal detected by pressure sensor 5.

[0200] In this embodiment, by setting a pressure sensor 5 that is electrically connected to the control board, the pressure change in the water storage tank 61 can be detected in time and fed back to the control board, thereby automatically controlling the start and stop of the heating plate 7, avoiding the occurrence of dry burning and improving the safety and reliability of the steam humidification device.

[0201] When the pressure sensor 5 detects that the pressure in the water storage tank 61 has dropped to the set value, the electronic control board will cut off the power supply to the heating plate 7.

[0202] It should be noted that the electronic control board is the main control board of the wall-mounted air conditioner indoor unit 100. It is used to receive signals, analyze signals, and issue control commands to realize the electronic control functions of the wall-mounted air conditioner indoor unit 100.

[0203] It is understandable that the electronic control board contains the components required to control the operation of the indoor unit 100 of the wall-mounted air conditioner. This is existing technology in the field and will not be described in detail here.

[0204] When the water temperature in the water storage tank 61 is too high, the amount of steam generated in the water storage tank 61 is large. In order to avoid the excessive amount of steam generated in the water storage tank 61, it is necessary to prevent the water in the water storage tank 61 from boiling. Therefore, it is necessary to maintain the water temperature in the water storage tank 61 within the preset range.

[0205] It should be noted that the reference Figure 13 , Figure 14 The bottom of the housing 9 is provided with a through hole 97. The heating plate 7 and the pressure sensor 5 pass through the through hole 97 and abut against the connection part 65 of the water tank 6.

[0206] In some embodiments of this application, in order to ensure that the water temperature in the water storage tank 61 can be maintained within a preset range, a temperature sensor is provided at the heating plate 7 to detect the temperature of the heating plate 7.

[0207] The temperature sensor is electrically connected to the control board, which is configured to turn on or off the power supply to the heating plate 7 based on the temperature detected by the temperature sensor.

[0208] For example, when the temperature of the heating plate 7 exceeds the upper limit of the preset range, the control board controls the heating plate 7 to cut off the power, and when the temperature of the heating plate 7 drops to the lower limit of the preset range, the control board controls the heating plate 7 to restore the power supply.

[0209] In this embodiment, considering that the material heat deformation temperature of the casing 1 of the indoor unit 100 of the wall-mounted air conditioner is 93~118℃, and the heating plate 7 needs to ensure that the material of the casing 1 does not deform when heating, the preset range is set to 60~80℃.

[0210] By setting a temperature sensor, precise control of the temperature of the heating plate 7 is achieved, ensuring that the heating plate 7 operates within a suitable temperature range. This not only guarantees heating efficiency but also avoids problems such as deformation of the casing 1, material damage, and excessively rapid steam generation caused by excessively high heating plate 7 temperatures. At the same time, it also prevents situations where the heating plate 7 temperatures are too low to effectively generate steam, thus ensuring the normal operation and humidification effect of the steam humidification device.

[0211] In some embodiments of this application, the steam humidification device may include a thermostat connected in series in the power supply circuit of the heating plate 7.

[0212] The thermostat is configured to disconnect or connect the power supply circuit according to the temperature of the heating plate 7, that is, to control the power supply to the heating plate 7 or to stop the power supply to the heating plate 7.

[0213] By setting a thermostat, precise control of the temperature of the heating plate 7 is achieved, ensuring that the heating plate 7 operates within a suitable temperature range.

[0214] In some embodiments, the thermostat may be a bimetallic thermostat.

[0215] It should be noted that a bimetallic thermostat is formed by welding or bonding two metal strips with different coefficients of thermal expansion together to create a bimetallic strip.

[0216] When the temperature of the heating plate 7 rises, the metal strip with a larger coefficient of expansion expands more, causing the entire bimetallic strip to bend; conversely, when the temperature of the heating plate 7 decreases, the metal strip with a smaller coefficient of expansion contracts, causing the bimetallic strip to return to its original shape. The working principle of the bimetallic strip thermostat is well known to those skilled in the art, and therefore will not be described in detail.

[0217] In some embodiments, the magnetic rotor 81 is configured to correspond to the heating plate 7.

[0218] The magnetic rotor 81 is positioned to correspond to the heating plate 7, which enables the magnetic stirrer 8 to more effectively stir the water in the water storage tank 61, further improving the humidification effect and humidification range.

[0219] 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.

[0220] For ease of explanation, the above description has been provided in conjunction with specific embodiments. However, the above exemplary discussion is not intended to be exhaustive or to limit the embodiments to the specific forms disclosed above. Various modifications and variations can be obtained based on the above teachings.
